Construction of a predictive model for acute liver failure after hepatectomy based on neutrophil-to-lymphocyte ratio and albuminbilirubin score

BACKGROUND Acute liver failure(ALF)is a common cause of postoperative death in patients with hepatocellular carcinoma(HCC)and is a serious threat to patient safety.The neutrophil-to-lymphocyte ratio(NLR)is a common inflammatory indicator that is associated with the prognosis of various diseases,and the albumin-bilirubin score(ALBI)is used to evaluate liver function in liver cancer patients.Therefore,this study aimed to construct a predictive model for postoperative ALF in HCC tumor integrity resection(R0)based on the NLR and ALBI,providing a basis for clinicians to choose appropriate treatment plans.AIM To construct an ALF prediction model after R0 surgery for HCC based on NLR and ALBI.METHODS In total,194 patients with HCC who visited The First People’s Hospital of Lianyungang to receive R0 between May 2018 and May 2023 were enrolled and divided into the ALF and non-ALF groups.We compared differences in the NLR and ALBI between the two groups.The risk factors of ALF after R0 surgery for HCC were screened in the univariate analysis.Independent risk factors were analyzed by multifactorial logistic regression.We then constructed a prediction model of ALF after R0 surgery for HCC.A receiver operating characteristic curve,calibration curve,and decision curve analysis(DCA)were used to evaluate the value of the prediction model.RESULTS Among 194 patients with HCC who met the standard inclusion criteria,46 cases of ALF occurred after R0(23.71%).There were significant differences in the NLR and ALBI between the two groups(P<0.05).The univariate analysis showed that alpha-fetoprotein(AFP)and blood loss volume(BLV)were significantly higher in the ALF group compared with the non-ALF group(P<0.05).The multifactorial analysis showed that NLR,ALBI,AFP,and BLV were independent risk factors for ALF after R0 surgery in HCC.The predictive efficacy of NLR,ALBI,AFP,and BLV in predicting the occurrence of ALT after R0 surgery for HCC was average[area under the curve(AUC)NLR=0.767,AUCALBI=0.755,AUCAFP=0.599,AUCBLV=0.718].The prediction model for ALF after R0 surgery for HCC based on NLR and ALBI had a better predictive efficacy(AUC=0.916).The calibration curve and actual curve were in good agreement.DCA showed a high net gain and that the model was safer compared to the curve in the extreme case over a wide range of thresholds.CONCLUSION The prediction model based on NLR and ALBI can effectively predict the risk of developing ALF after HCC R0 surgery,providing a basis for clinical prevention of developing ALF after HCC R0 surgery.

Nomogram based on liver stiffness and spleen area with ultrasound for posthepatectomy liver failure:A multicenter study

BACKGROUND Liver stiffness(LS)measurement with two-dimensional shear wave elastography(2D-SWE)correlates with the degree of liver fibrosis and thus indirectly reflects liver function reserve.The size of the spleen increases due to tissue proliferation,fibrosis,and portal vein congestion,which can indirectly reflect the situation of liver fibrosis/cirrhosis.It was reported that the size of the spleen was related to posthepatectomy liver failure(PHLF).So far,there has been no study combining 2D-SWE measurements of LS with spleen size to predict PHLF.This prospective study aimed to investigate the utility of 2D-SWE assessing LS and spleen area(SPA)for the prediction of PHLF in hepatocellular carcinoma(HCC)patients and to develop a risk prediction model.AIM To investigate the utility of 2D-SWE assessing LS and SPA for the prediction of PHLF in HCC patients and to develop a risk prediction model.METHODS This was a multicenter observational study prospectively analyzing patients who underwent hepatectomy from October 2020 to March 2022.Within 1 wk before partial hepatectomy,ultrasound examination was performed to measure LS and SPA,and blood was drawn to evaluate the patient’s liver function and other conditions.Least absolute shrinkage and selection operator logistic regression and multivariate logistic regression analysis was applied to identify independent predictors of PHLF and develop a nomogram.Nomogram performance was validated further.The diagnostic performance of the nomogram was evaluated with receiver operating charac-teristic curve compared with the conventional models,including the model for end-stage liver disease(MELD)score and the albumin-bilirubin(ALBI)score.RESULTS A total of 562 HCC patients undergoing hepatectomy(500 in the training cohort and 62 in the validation cohort)were enrolled in this study.The independent predictors of PHLF were LS,SPA,range of resection,blood loss,international normalized ratio,and total bilirubin.Better diagnostic performance of the nomogram was obtained in the training[area under receiver operating characteristic curve(AUC):0.833;95%confidence interval(95%CI):0.792-0.873;sensitivity:83.1%;specificity:73.5%]and validation(AUC:0.802;95%CI:0.684-0.920;sensitivity:95.5%;specificity:52.5%)cohorts compared with the MELD score and the ALBI score.CONCLUSION This PHLF nomogram,mainly based on LS by 2D-SWE and SPA,was useful in predicting PHLF in HCC patients and presented better than MELD score and ALBI score.

Red cell distribution width/platelet ratio estimates the 3-year risk of decompensation in Metabolic Dysfunction-Associated Steatotic Liver Disease-induced cirrhosis

BACKGROUND For compensated advanced chronic liver disease(cACLD)patients,the first decompensation represents a dramatically worsening prognostic event.Based on the first decompensation event(DE),the transition to decompensated advanced chronic liver disease(dACLD)can occur through two modalities referred to as acute decompensation(AD)and non-AD(NAD),respectively.Clinically Significant Portal Hypertension(CSPH)is considered the strongest predictor of decompensation in these patients.However,due to its invasiveness and costs,CSPH is almost never evaluated in clinical practice.Therefore,recognizing noninvasively predicting tools still have more appeal across healthcare systems.The red cell distribution width to platelet ratio(RPR)has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease(MASLD).However,its predictive role for the decompensation has never been explored.AIM In this observational study,we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients.METHODS Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up(FUP)semiannually for 3 years.At baseline,biochemical,clinical,and Liver Stiffness Measurement(LSM),Child-Pugh(CP),Model for End-Stage Liver Disease(MELD),aspartate aminotransferase/platelet count ratio index(APRI),Fibrosis-4(FIB-4),Albumin-Bilirubin(ALBI),ALBI-FIB-4,and RPR were collected.During FUP,DEs(timing and modaities)were recorded.CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines.RESULTS Of 150 MASLD-related cACLD patients,43(28.6%)progressed to dACLD at a median time of 28.9 months(29 NAD and 14 AD).Baseline RPR values were significantly higher in cACLD in comparison to controls,as well as MELD,CP,APRI,FIB-4,ALBI,ALBI-FIB-4,and LSM in dACLD-progressing compared to cACLD individuals[all P<0.0001,except for FIB-4(P:0.007)and ALBI(P:0.011)].Receiving operator curve analysis revealed RPR>0.472 and>0.894 as the best cut-offs in the prediction respectively of 3-year first DE,as well as its superiority compared to the other non-invasive tools examined.RPR(P:0.02)and the presence of baseline-CSPH(P:0.04)were significantly and independently associated with the DE.Patients presenting baseline-CSPH and RPR>0.472 showed higher risk of decompensation(P:0.0023).CONCLUSION Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.

Monocyte to High-density Lipoprotein Cholesterol Ratio as a Predictor of Nonalcoholic Fatty Liver Disease in Childhood Obesity

Objective Inflammation is involved in the development and progression of nonalcoholic fatty liver disease(NAFLD).The monocyte to high-density lipoprotein cholesterol ratio(MHR)has emerged as a marker for various inflammation-related diseases.The aim of the present study was to investigate the association between the MHR and NAFLD in a population with childhood obesity.Methods Based on hepatic ultrasound,a total of 504 children with obesity(357 with NAFLD and 147 without NAFLD)were included in the study.The correlation between the MHR and NAFLD risk factors was assessed by Pearson’s and Spearman’s analyses.Multivariate stepwise logistic regression analyses were conducted to explore the association between the MHR and the risk of NAFLD.Results The MHR in patients with NAFLD was significantly greater than that in patients without NAFLD[0.52(0.44-0.67)versus 0.44(0.34-0.57),P<0.001].Multivariate stepwise logistic regression analysis demonstrated that the MHR[odds ratio(OR):1.033,95%confidence interval(CI):1.015-1.051;P<0.001]was an independent predictor of NAFLD in childhood obesity patients,as were age(OR:1.205,95%CI:1.059-1.371;P=0.005],waist circumference[OR:1.037,95%CI:1.008-1.067;P=0.012],and alanine transaminase[OR:1.067,95%CI:1.045-1.089;P<0.001].Additionally,MHR quartiles showed a significant positive association with the incidence of NAFLD after adjusting for potential confounding factors.Conclusion The present study showed that the MHR may serve as an available and useful indicator of NAFLD in individuals with childhood obesity.

Prognostic value of neutrophil-to-lymphocyte ratio in end-stage liver disease:A meta-analysis

BACKGROUND The neutrophil-to-lymphocyte ratio(NLR)is commonly utilized as a prognostic indicator in end-stage liver disease(ESLD),encompassing conditions like liver failure and decompensated cirrhosis.Nevertheless,some studies have contested the prognostic value of NLR in ESLD.AIM To investigate the ability of NLR to predict ESLD.METHODS Databases,such as Embase,PubMed,Web of Science,Cochrane Library,China National Knowledge Infrastructure,Weipu,and Wanfang,were comprehensively searched to identify studies published before October 2022 assessing the prognostic ability of NLR to predict mortality in patients with ESLD.Effect sizes were calculated using comprehensive meta-analysis software and SATAT 15.1.RESULTS A total of thirty studies involving patients with end-stage liver disease(ESLD)were included in the evaluation.Among the pooled results of eight studies,it was observed that the Neutrophil-to-Lymphocyte Ratio(NLR)was significantly higher in non-survivors compared to survivors(random-effects model:standardized mean difference=1.02,95%confidence interval=0.67-1.37).Additionally,twenty-seven studies examined the associations between NLR and mortality in ESLD patients,reporting either hazard ratios(HR)or odds ratios(OR).The combined findings indicated a link between NLR and ESLD mortality(randomeffects model;univariate HR=1.07,95%CI=1.05-1.09;multivariate HR=1.07,95%CI=1.07-1.09;univariate OR=1.29,95%CI=1.18-1.39;multivariate OR=1.29,95%CI=1.09-1.49).Furthermore,subgroup and meta-regression analyses revealed regional variations in the impact of NLR on ESLD mortality,with Asian studies demonstrating a more pronounced effect.CONCLUSION Increased NLR in patients with ESLD is associated with a higher risk of mortality,particularly in Asian patients.NLR is a useful prognostic biomarker in patients with ESLD.

Liver and spleen volume variations in patients with hepatic fibrosis

AIM： To study the liver and spleen volume variations in hepatic fibrosis patients at different histopathological stages. METHODS： Multidetector computed tomography （MDCT） scan was performed in 85 hepatic fibrosis patients. Liver volume （LV） and spleen volume （SV） were measured. Fifteen healthy individuals served as a control group （SO）. The patients were divided into stage 1 （S1） group （n = 34）, stage 2 （S2） group （n = 25）, stage 3 （S3） group （n = 16）, and stage 4 （S4） group （n = 10） according to their histopathological stage of liver fibrosis. RESULTS： The LV and standard LV （SLV） had a tendency to increase with the severity of fibrosis, but no statistical difference was observed in the 5 groups （LV： F = 0.245, P = 0.912; SLV： F = 1.902, P = 0.116）. The SV was gradually increased with the severity of fibrosis, and a statistically significant difference in SV was observed among the 5 groups （P 〈 0.01）. The LV/SV ratio and SLV/SV ratio were gradually decreased with the aggravation of hepatic fibrosis, and statistically significant differences in both LV/SV and SLV/SV were found among the 5 groups （P 〈 0.01）.CONCLUSION： The absence of obvious LV reduction in patients with chronic liver disease may be a morphological index of patients without liver cirrhosis. The SV is related to the severity of fibrosis, and the spleen of patients with advanced fibrosis is enlarged evidently. The LV/SV ratio and SLV/SV ratio are of a significant clinical value in the diagnosis of advanced liver fibrosis.

Platelet-to-lymphocyte ratio in the setting of liver transplantation for hepatocellular cancer: A systematic review and meta-analysis

AIM To perform a systematic review and meta-analysis on platelet-to-lymphocyte ratio(PLR) as a risk factor for post-transplant hepatocellular cancer(HCC) recurrence. METHODS A systematic literature search was performed using PubM ed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria:(1) studies comparing pre-transplant low vs high PLR values;(2) studies reporting post-transplant recurrence rates; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measure was set for HCC recurrence after transplantation. RESULTS A total of 5 articles, published between 2014 and 2017, fulfilled the selection criteria. As for the quality of the reported studies, all the investigated articles presented an overall high quality. A total of 899 cases were investigated: 718 cases(80.0%) were males. Three studies coming from European countries and one from Japan presented HCV as the main cause of cirrhosis. On the opposite, one Chinese study presented a greater incidence of HBV-related cirrhotic cases. In all the studies apart one, the PLR cut-off value of 150 was reported. At meta-analysis, high PLR value was associated with a significant increase in recurrence after transplantation(OR = 3.33; 95%CI: 1.78-6.25; P < 0.001). A moderate heterogeneity was observed among the identified studies according to the Higgins I^2 statistic value.CONCLUSION Pre-transplant high PLR values are connected with an increased risk of post-operative recurrence of hepatocellular cancer. More studies are needed for better clarify the biological mechanisms of this results.

Inflammatory pseudotumor of the liver and spleen diagnosed by percutaneous needle biopsy

An inflammatory pseudotumor (IPT) is a relatively rare lesion characterized by chronic inf iltration of inflammatory cells and areas of f ibrosis. IPTs are diff icult to diagnose because of the absence of specif ic symptoms or of characteristic hematological or radiological f indings. In this study, a case of a woman aged over 70 years was reported, who presented with a general malaise lasting more than two months. A computed tomography scan demonstrated a diffusely spread lesion of the liver with a portal vein occlusion and a splenic lesion surrounded by a soft density layer. Since the percutaneous liver biopsy showed f indings that suggested an IPT, although the radiological f indings did not exclude the possibility of a malignancy, we performed a percutaneous spleen biopsy to enable a more defi nitive diagnosis. The microscopic f indings from the spleen specimen lead us to a diagnosis of IPT involving the liver and spleen. Sub-sequent steroid pulse therapy was effective, and rapid resolution of the disease was observed.

Diagnostic value of FIB-4, aspartate aminotransferaseto-platelet ratio index and liver stiffness measurement in hepatitis B virus-infected patients with persistently normal alanine aminotransferase

AIM To assess the diagnostic value of FIB-4, aspartate aminotransferase-to-platelet ratio index(APRI), and liver stiffness measurement(LSM) in patients with hepatitis B virus infection who have persistently normal alanine transaminase(PNALT).METHODS We enrolled 245 patients with chronic hepatitis B: 95 in PNALT group, 86 in intermittently elevated alanine transaminase(PIALT1) group [alanine transaminase(ALT) within 1-2 × upper limit of normal value(ULN)], and 64 in PIALT2 group(ALT > 2 × ULN). All the patients received a percutaneous liver biopsy guided by ultrasonography. LSM, biochemical tests, and complete blood cell counts were performed.RESULTS The pathological examination revealed moderate inflammatory necrosis ratios of 16.81%(16/95), 32.56%(28/86), and 45.31%(28/64), and moderate liverfibrosis of 24.2%(23/95), 33.72%(29/86), and 43.75%(28/64) in the PNALT, PIALT1, and PIALT2 groups, respectively. The degrees of inflammation and liver fibrosis were significantly higher in the PIALT groups than in the PNALT group(P < 0.05). No significant difference was found in the areas under the curve(AUCs) between APRI and FIB-4 in the PNALT group; however, significant differences were found between APRI and LSM, and between FIB-4 and LSM in the PNALT group(P < 0.05 for both). In the PIALT1 and PIALT2 groups, no significant difference(P > 0.05) was found in AUCs for all comparisons(P > 0.05 for all). In the overall patients, a significant difference in the AUCs was found only between LSM and APRI(P < 0.05).CONCLUSION APRI and FIB-4 are not the ideal noninvasive hepatic fibrosis markers for PNALT patients. LSM is superior to APRI and FIB-4 in PNALT patients because of the influence of liver inflammation and necrosis.

Nonalcoholic fatty liver disease, spleen and psoriasis:New aspects of low-grade chronic inflammation

AIM: To investigate spleen status in psoriasis and itsrelationship with hepatic steatosis, Psoriasis Area and Severity Index, and insulin resistance.METHODS: Seventy-nine psoriatic patients who were not suffering from any chronic inflammatory disease were retrospectively selected for inclusion in this study,and their complete medical records were accessed.An age- and sex-matched group of 80 non-psoriatic,obese patients was included as a control. The following relevant data were collected: age, sex, weight, height,body mass index, waist circumference, blood pressure,insulin resistance status, age at psoriasis onset, and severity of psoriasis. Abdominal ultrasonography was performed to determine spleen longitudinal diameter(SLD), and hepatic steatosis grade.RESULTS: The SLD of control obese patients was greater than that of psoriatic subjects(P = 0.013),but body mass index predicted the size of the spleen in psoriatic patients(P < 0.001). The SLD of psoriatic patients with normal weight was significantly reduced with respect to the overweight/obese psoriatic patients(P = 0.002). A multiple regression analysis revealed that body mass index was a unique predictor of the spleen size(P < 0.001). Finally, the disease duration predicted the spleen size in psoriatic subjects(P =0.038).CONCLUSION: This study shows a correlation between the SLD and the duration of psoriasis.

Functional distinction of rat liver natural killer cells from spleen natural killer cells under normal and acidic conditions in vitro

BACKGROUND: The microenvironment within solid tumors has often been shown to exhibit an acidic extracellular pH. Although the morphologic and functional differences in natural killer (NK) cells of the liver and spleen have been reported previously under physiological conditions, the difference under acidic conditions is still unclear. This study was to investigate the differences in the morphological and functional characteristics between rat liver and spleen NK cells under normal and acidic conditions in vitro. METHODS: Liver and spleen NK cells were isolated and purified from Sprague-Dawley rats by density gradient centrifugation and the Dynabeads FlowComp TM Flexi system, and stimulated for 4 days with or without IL-2 or treated with low pH or control for different times. Morphology was examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), cell death and proliferation assays were performed by flow cytometry, IFN-γ production was tested by ELISA, and cytotoxic activity was evaluated by lactate dehydrogenase (LDH) release assay. RESULTS: Liver NK cells had significantly higher levels of cytotoxic activity than spleen NK cells under normal and acidic conditions, and the maximum difference was observed at pH 5.6. Further analysis revealed that the cytotoxic activity of NK cells was correlated with morphology, cell death, proliferative activity and IFN-γ production. By TEM, liver NK cells contained a greater number of electron-dense granules per cell at pH 5.6.Moreover, a modest elevation of cell death and reduction of proliferation of liver NK cells occurred within a range of 5.6-7.2. Interestingly, an acidic extracellular pH only marginally, and not significantly, suppressed IFN-γ production by liver NK cells. CONCLUSION: The sharp morphological and functional differences shown by the two types of NK cells in vitro indicate that liver NK cells are unexpectedly resistant to pH shock.

Beh et's disease complicated by multiple aseptic abscesses of the liver and spleen

Aseptic abscesses are an emergent entity and have been described in inflammatory bowel disease,especially in Crohn's disease,and in other diseases.However,aseptic abscesses associated with Beh et's disease are extremely rare.We report a Japanese male diagnosed with an incomplete type of Beh et's disease who developed multiple aseptic abscesses of the spleen and liver.In 2002,the spleen abscesses were accompanied by paroxysmal oral aphthous ulcers and erythema nodosum.As the patient's response to antibiotic treatment was inadequate,a splenectomy was performed.Severe inflammatory cell infiltration,largely of polymorphonuclear neutrophils,was observed without evidence of bacterial or fungal growth.Although the patient had no history of ocular symptoms or genital ulcers,a diagnosis of incomplete Beh et's disease was made according to the Japanese diagnostic criteria because of the presence of paroxysmal arthritis and epididymitis since 2002.In 2005,multiple liver abscesses developed with right hypochondrial pain and seemed to be attributed to Beh et's disease because the abscesses yielded negative results during a microbiologic investigation and failed to go into remission under antibiotic therapy.Oral prednisone(15 mg/d) was started in May 2006,and the abscesses dramatically disappeared 4 wk after treatment.Although the patient had a relapse of the liver abscesses in association with the tapering of prednisone,the augmentation of prednisone dosage yielded a response.The abscesses of the liver and spleen were strongly suggested to be attributed to Beh et's disease.Clinician should be aware of the existence of aseptic abscesses as uncommon manifestations of Beh et's disease.

Noninvasive assessment of liver fibrosis with combined serum aminotransferase/platelet ratio index and hyaluronic acid in patients with chronic hepatitis B

AIM： To construct a noninvasive assessment model consisting of routine laboratory data to predict significant fibrosis and cirrhosis in patients with chronic hepatitis B （CHB）. METHODS： A total of 137 consecutive patients with CriB who underwent percutaneous liver biopsy were retrospectively analyzed. These patients were divided into two groups according to their aminotransferase （ALT） level. The sensitivity, specificity, positive predictive value （PPV）, negative predictive value （NPV）, the likelihood ratio （LR） of aminotransferase/platelet ratio index （APRI） ≥ 1.5 or 〈 1.5 in combination with different hyaluronic acid （HA） cut-off points were calculated for the presence of moderate to severe fibrosis/cirrhosis （fibrosis stages 2 and 4） and no to mild fibrosis/cirrhosis （fibrosis stages 0 and 1）. RESULTS： The APRI correlated with fibrosis stage in CriB patients. The APRI ≥1.5 in combination with a cut-off HA cut-off point 〉 300 ng/mL could detect moderate to severe fibrosis （stages 2-4） in Crib patients. The PPV was 93.7%, the specificity was 98.9%. The APRI 〈 1.5 in combination with different HA cut-off points could not detect no to mild fibrosis in CHB patients. CONCLUSION： The APRI ≥ 1.5 in combination with a HA cut-off point 〉 300 ng/mL can detect moderate to severe fibrosis （stages 2-4） in Crib patients.

Clinical value of liver and spleen shear wave velocity in predicting the prognosis of patients with portal hypertension

AIM To explore the relationship of liver and spleen shear wave velocity in patients with liver cirrhosis combined with portal hypertension,and assess the value of liver and spleen shear wave velocity in predicting the prognosis of patients with portal hypertension.METHODS All 67 patients with liver cirrhosis diagnosed as portal hypertension by hepatic venous pressure gradient in our hospital from June 2014 to December 2014 were enrolled into this study. The baseline information of these patients was recorded. Furthermore,67 patients were followed-up at 20 mo after treatment,and liver and spleen shear wave velocity were measured by acoustic radiation force impulse at the 1^(st) week,3^(rd) month and 9^(th) month after treatment. Patients with favorable prognosis were assigned into the favorable prognosis group,while patients with unfavorable prognosis were assigned into the unfavorable prognosis group. The variation and difference in liver and spleen shear wave velocity in these two groups were analyzed by repeated measurement analysis of variance. Meanwhile,in order to evaluate the effect of liver and spleen shear wave velocity on the prognosis of patients with portal hypertension,Cox's proportional hazard regression model analysis was applied. The ability of those factors in predicting the prognosis of patients with portal hypertension was calculated through receiver operating characteristic(ROC) curves.RESULTS The liver and spleen shear wave velocity in the favorable prognosis group revealed a clear decline,while those in the unfavorable prognosis group revealed an increasing tendency at different time points. Furthermore,liver and spleen shear wave velocity was higher in the unfavorable prognosis group,compared with the favorable prognosis group; the differences were statistically significant(P < 0.05). The prognosis of patients with portal hypertension was significantly affected by spleen hardness at the 3^(rd) month after treatment [relative risk(RR) = 3.481]. At the 9^(th) month after treatment,the prognosis was affected by liver hardness(RR = 5.241) and spleen hardness(RR = 7.829). The differences between these two groups were statistically significant(P < 0.05). The ROC analysis revealed that the area under the curve(AUC) of spleen hardness at the 3^(rd) month after treatment was 0.644,while the AUCs of liver and spleen hardness at the 9^(th) month were 0.579 and 0.776,respectively. These might predict the prognosis of patients with portal hypertension.CONCLUSION Spleen hardness at the 3^(rd) month and liver and spleen shear wave velocity at the 9^(th) month may be used to assess the prognosis of patients with portal hypertension. This is hoped to be used as an indicator of predicting the prognosis of patients with portal hypertension.

Non-invasive model for predicting esophageal varices based on liver and spleen volume

BACKGROUND Upper endoscopy is the gold standard for predicting esophageal varices in China.Guidelines and consensus suggest that patients with liver cirrhosis should undergo periodic upper endoscopy,most patients undergo their first upper endoscopy when esophageal variceal bleeds.Therefore,it is important to develop a non-invasive model to early diagnose esophageal varices.AIM To develop a non-invasive predictive model for esophageal varices based on liver and spleen volume in viral cirrhosis patients.METHODS We conducted a cross-sectional study based on viral cirrhosis crowd in the Second Affiliated Hospital of Xi'an Jiaotong University.By collecting the basic information and clinical data of the participants,we derived the independent risk factors and established the prediction model of esophageal varices.The established model was compared with other models.Area under the receiver operating characteristic curve,calibration plot and decision curve analysis were used to test the discriminating ability,calibration ability and clinical practicability in both the internal and external validation.RESULTS The portal vein diameter,the liver and spleen volume,and volume change rate were the independent risk factors of esophageal varices.We successfully used the factors to establish the predictive model[area under the curve(AUC)0.87,95%CI:0.80-0.95],which showed better predictive value than other models.The model showed good discriminating ability,calibration ability and the clinical practicability in both modelling group and external validation group.CONCLUSION The developed non-invasive predictive model can be used as an effective tool for predicting esophageal varices in viral cirrhosis patients.

Biological basis of “depression with liver-qi stagnation and spleen deficiency syndrome”: A digital gene expression profiling study

Objective:To investigate the biological basis of“depression with liver-qi stagnation and spleen deficiency syndrome”.Methods:A digital gene expression profiling method was conducted to explore global changes in the mRNA transcriptome in a rat model of depression with liver-qi stagnation and spleen deficiency syndrome.Real-time quantitative polymerase chain reaction(q-PCR)was performed to verify the five genes most interest based on the Kyoto Encyclopedia of Genes and Genome(KEGG)analysis.Sini San,which disperses stagnated liver qi and strengthens the spleen,was administered to the model rats to observe whether it could reverse these genetic changes in the liver.Results:Forty-six differentially expressed genes were identified.Three of the five genes of most interestdHnf4a,Hnf4g and Cyp1a1dbased on KEGG analysis,were confirmed by realtime q-PCR.Sini San reduced the gene expression changes of Hnf4a,Hnf4g and Cyp1a1 in the rat model.Conclusions:Hnf4a,Hnf4g and Cyp1a1 are involved in“depression with liver-qi stagnation and spleen deficiency syndrome”.These findings indicate that depressed rats with liver-qi stagnation and spleen deficiency syndrome are at risk of liver diseases.Furthermore,our results will inform exploration of the etiology of depression and help in the development of effective therapeutic strategies.

Rat Models of Fatty Liver due to Liver Depression and Spleen Deficiency

[Objectives] To establish animal models of fatty liver due to liver depression and spleen deficiency that were suitable for activity discovery of traditional Chinese medicine( TCM) compounds,efficacy evaluation,new drug research and development and correspondence between prescription and syndrome of TCM. [Methods] A syndrome score scale that was suitable for evaluating the rat models was established according to the evolvement rules of etiology and pathogenesis of TCM and the modern clinical pathological mechanism. At the same time,bifendate pills and Sanqi Zhigan pills were selected as drug counterevidence for the models. Rats in model groups were given different proportions of high-fat and low-protein fodder and different concentrations of alcohol every day,and intraperitoneally injected with porcine serum twice a week. Drug groups were given with bifendate pills and Sanqi Zhigan pills( 8. 1 mg/kg,and 2. 7 g/kg) respectively for 14 consecutive days.During the experiment,general status,weight,daily fodder intake and daily water intake of the animals were observed,and TCM syndromes were scored. After the experiment,the levels of alanine aminotransferase( ALT),aspartate aminotransferase( AST),γ-glutamine transpeptidase( γ-GT),total cholesterol( TC),triglycerides( TG),low density lipoprotein-cholesterol( LDL-C),and high density lipoprotein-cholesterol( HDL-C) in serum were detected,and the pathological changes in liver tissue were observed. [Results] Compared with the control group,body weight,daily fodder and water intake of rats increased slowly in the model group,and the levels of ALT,AST,γ-GT,TC,TG and LDL-C increased significantly,while the level of HDL-C dropped. Pathological examination showed that steatosis and fat granule were observed in hepatocytes of rats in the model group. Behavioral observation found that main symptoms and minor symptoms of rats in the model group conformed to the syndrome manifestation of liver depression and spleen deficiency,which suggested that the three model groups were established successfully. Among them,three rats died in model group 1,and one rat died in model group 2. The manifestation of all the above lesions can be alleviated by drug counterevidence. [Conclusions]The animal model of fatty liver due to liver depression and spleen deficiency shows an obviously lower mortality and shorter duration and can be used for research of correlation between prescription and syndrome and its mechanism.

Experience of Treating Hypertension from Liver and Spleen Among Middle-Aged and Young Patients:A Summary

Qi deficiency of the spleen and stomach,transportation,phlegm and dampness generate endogenous and turbid phlegm that violates the position of yang clearance.As a result,dizziness cis resulted.The author believes that the incidence of middle-aged and young patients with hypertension is mostly related to the dysfunction of liver and spleen.Liver depression and qi stagnation is the beginning of the onset;spleen deficiency and dyskinesia is the norm of the onset;and liver and spleen imbalance is the origin of the onset.It is advocated that regulating the liver and spleen to restore the rise and fall,harmonizing qi and blood and preventing lesions are the main treatment methods for the treatment of middle-aged and young people’s hypertension,which is conducive to the development of more clinical diagnosis and treatment ideas for hypertension amomg middle-aged and young people.

Theoretical Discussion on Treatment of Cubital Tunnel Syndrome Based on Theory of Liver,Spleen and Kidney

Cubital tunnel syndrome is a disease in which ulnar nerve is compressed by its surrounding tissues,and its main clinical manifestations are pain,sensory disturbance and dyskinesia.Its incidence rate is the second highest among peripheral nerve entrapment diseases,and it is one of the common clinical diseases.The theory of liver,spleen and kidney can guide the treatment of cubital tunnel syndrome with traditional Chinese medicine and acupuncture.By discussing the traditional Chinese medicine(TCM)pathogenesis and treatment principles of cubital tunnel syndrome,it provides modern medical theoretical support for TCM treatment of cubital tunnel syndrome.

Study on the Characteristics of Gut Microbiota in Chronic Hepatitis B(CHB)Patients with Damp Heat Syndrome and Liver Depression and Spleen Deficiency Syndrome

Objective:This study was designed to explore the characteristics of gut microbiota in CHB patients with two most common traditional Chinese medicine(TCM)Syndromes—damp heat syndrome and liver depression and spleen deficiency syndrome.Methods:According to the diagnostic criteria of Western medicine,TCM and screening exclusion criteria,65 cases of CHB with damp heat syndrome and 28 cases of CHB with liver depression and spleen deficiency syndrome were finally included in the study.All the basic information was gathered and the fresh fecal samples were collected for 16S rDNA sequencing.16S rDNA of gut microbiota was sequenced using Illumina hiseq 2,500 high-throughput sequencing platform.Based on the optimized sequence,Operational Taxonomic Units(OTU)clustering analysis and taxonomic annotation were carried out.Results:The difference in relative abundance of gut microbiota was significant between damp heat syndrome and liver depression and spleen deficiency syndrome in CHB patients.Cyanobacteria was only found in damp heat syndrome.The relative abundance of Erysipelotrichia and Subdoligranulum were higher in liver depression and spleen deficiency syndrome,while the relative abundance of Rhodospirillales,Alphaproteobacteria and Lachnospira were higher in the damp heat syndrome.LDA Effect Size(LEfSe)analysis showed that Lachnospira,Olsenella and Subdoligranulum had significant difference in species among the two TCM syndromes.Conclusion:The different characteristics of gut microbiota in the two TCM syndromes of CHB patients may play an important role in syndrome formation of TCM,which provides a new field of vision for the accurate diagnosis and treatment of TCM.
