Microglia lactylation in relation to central nervous system diseases

The development of neurodegenerative diseases is closely related to the disruption of central nervous system homeostasis.Microglia,as innate immune cells,play important roles in the maintenance of central nervous system homeostasis,injury response,and neurodegenerative diseases.Lactate has been considered a metabolic waste product,but recent studies are revealing ever more of the physiological functions of lactate.Lactylation is an important pathway in lactate function and is involved in glycolysis-related functions,macrophage polarization,neuromodulation,and angiogenesis and has also been implicated in the development of various diseases.This review provides an overview of the lactate metabolic and homeostatic regulatory processes involved in microglia lactylation,histone versus non-histone lactylation,and therapeutic approaches targeting lactate.Finally,we summarize the current research on microglia lactylation in central nervous system diseases.A deeper understanding of the metabolic regulatory mechanisms of microglia lactylation will provide more options for the treatment of central nervous system diseases.

Pachymic acid exerts antitumor activities by modulating the Wnt/β-catenin signaling pathway via targeting PTP1B

Objective:To determine the inhibitory effects of pachymic acid on lung adenocarcinoma(LUAD)cells and elucidate its underlying mechanism.Methods:CCK-8,wound healing,Transwell,Western blot,tube formation,and immunofluorescence assays were carried out to measure the effects of various concentrations of pachymic acid on LUAD cell proliferation,metastasis,angiogenesis as well as autophagy.Subsequently,molecular docking technology was used to detect the potential targeted binding association between pachymic acid and protein tyrosine phosphatase 1B(PTP1B).Moreover,PTP1B was overexpressed in A549 cells to detect the specific mechanisms of pachymic acid.Results:Pachymic acid suppressed LUAD cell viability,metastasis as well as angiogenesis while inducing cell autophagy.It also targeted PTP1B and lowered PTP1B expression.However,PTP1B overexpression reversed the effects of pachymic acid on metastasis,angiogenesis,and autophagy as well as the expression of Wnt3a andβ-catenin in LUAD cells.Conclusions:Pachymic acid inhibits metastasis and angiogenesis,and promotes autophagy in LUAD cells by modulating the Wnt/β-catenin signaling pathway via targeting PTP1B.

Efficacy of ginseng-based Renshenguben oral solution for cancer-related fatigue among patients with advanced-stage hepatocellular carcinoma:A prospective multicenter cohort study

Background:Cancer-related fatigue(CRF)is a common and debilitating symptom experienced by patients with advanced-stage cancer,especially those undergoing antitumor therapy.This study aimed to evaluate the efficacy and safety of Renshenguben(RSGB)oral solution,a ginseng-based traditional Chinese medicine,in alleviating CRF in patients with advanced hepatocellular carcinoma(HCC)receiving antitumor treatment.Methods:In this prospective,open-label,controlled,multicenter study,patients with advanced HCC at BCLC stage C and a brief fatigue inventory(BFI)score of≥4 were enrolled.Participants were assigned to the RSGB group(RSGB,10 mL twice daily)or the control group(with supportive care).Primary and secondary endpoints were the change in multidimensional fatigue inventory(MFI)score,and BFI and functional assessment of cancer therapy-hepatobiliary(FACT-Hep)scores at weeks 4 and 8 after enrollment.Adverse events(AEs)and toxicities were assessed.Results:A total of 409 participants were enrolled,with 206 assigned to the RSGB group.At week 4,there was a trend towards improvement,but the differences were not statistically significant.At week 8,the RSGB group exhibited a significantly lower MFI score(P<0.05)compared to the control group,indicating improved fatigue levels.Additionally,the RSGB group showed significantly greater decrease in BFI and FACT-Hep scores at week 8(P<0.05).Subgroup analyses among patients receiving various antitumor treatments showed similar results.Multivariate linear regression analyses revealed that the RSGB group experienced a significantly substantial decrease in MFI,BFI,and FACT-Hep scores at week 8.No serious drug-related AEs or toxicities were observed.Conclusions:RSGB oral solution effectively reduced CRF in patients with advanced HCC undergoing antitumor therapy over an eight-week period,with no discernible toxicities.These findings support the potential of RSGB oral solution as an adjunctive treatment for managing CRF in this patient population.

General anesthetic agents induce neurotoxicity through oligodendrocytes in the developing brain

General anesthetic agents can impact brain function through interactions with neurons and their effects on glial cells.Oligodendrocytes perform essential roles in the central nervous system,including myelin sheath formation,axonal metabolism,and neuroplasticity regulation.They are particularly vulnerable to the effects of general anesthetic agents resulting in impaired proliferation,differentiation,and apoptosis.Neurologists are increasingly interested in the effects of general anesthetic agents on oligodendrocytes.These agents not only act on the surface receptors of oligodendrocytes to elicit neuroinflammation through modulation of signaling pathways,but also disrupt metabolic processes and alter the expression of genes involved in oligodendrocyte development and function.In this review,we summarize the effects of general anesthetic agents on oligodendrocytes.We anticipate that future research will continue to explore these effects and develop strategies to decrease the incidence of adverse reactions associated with the use of general anesthetic agents.

Imaging, pathology, and diagnosis of solitary fibrous tumor of the pancreas: A case report and review of literature

BACKGROUND A solitary fibrous tumor(SFT)is often located in the pleura,while SFT of the pancreas is extremely rare.Here,we report a case of SFT of the pancreas and discuss imaging,histopathology,and immunohistochemistry for accurate diagnosis and treatment.CASE SUMMARY A 54-year-old man presented to our hospital with pancreatic occupancy for over a month.There were no previous complaints of discomfort.His blood pressure was normal.Blood glucose,tumor markers,and enhanced computed tomography(CT)suggested a malignant tumor.Because the CT appearance of pancreatic cancer varies,we could not confirm the diagnosis;therefore,we performed endoscopic ultrasound-guided fine-needle biopsy(EUS-FNB).Pathology and immunohistochemistry were consistent with SFT of the pancreas.The posto-perative pathology and immunohistochemistry were consistent with the puncture results.The patient presented for a follow-up examination one month after discharge with no adverse effects.CONCLUSION Other diseases must be excluded in patients with a pancreatic mass that cannot be diagnosed.CT and pathological histology have diagnostic value for pancreatic tumors.Endoscopic puncture biopsy under ultrasound can help diagnose pancreatic masses that cannot be diagnosed preoperatively.Surgery is an effective treatment for SFT of the pancreas;however,long-term follow-up is strongly recommended because of the possibility of malignant transformation of the tumor.

A mixed blessing for liver transplantation patients—Rapamycin

Background:Liver transplantation(LT)is an effective treatment option for end-stage liver disease.Mammalian target of rapamycin(m TOR)inhibitors,such as rapamycin,are widely used post LT.Data sources:In this review,we focused on the anti-cancer activities and metabolic side effects of rapamycin after LT.The literature available on Pub Med for the period of January 1999-September 2022 was reviewed.The key words were rapamycin,sirolimus,liver transplantation,hepatocellular carcinoma,diabetes,and lipid metabolism disorder.Results:Rapamycin has shown excellent effects and is safer than other immunosuppressive regimens.It has exhibited excellent anti-cancer activity and has the potential in preventing hepatocellular carcinoma(HCC)recurrence post LT.Rapamycin is closely related to two long-term complications after LT,diabetes and lipid metabolism disorders.Conclusions:Rapamycin prevents HCC recurrence post LT in some patients,but it also induces metabolic disorders.Reasonable use of rapamycin benefits the liver recipients.

Sirolimus improves the prognosis of liver recipients with hepatocellular carcinoma:A single-center experience

Background:Tumor recurrence after liver transplantation(LT)for selective patients diagnosed with hepatocellular carcinoma(HCC)in the setting of cirrhosis is the greatest challenge effecting the prognosis of these patients.The aim of this study was to evaluate the efficacy of sirolimus on the prognosis for these recipients.Methods:The data from 193 consecutive HCC patients who had undergone LT from January 2015 to December 2019 were retrospectively analyzed.These patients were divided into the sirolimus group[patients took sirolimus combined with calcineurin inhibitors(CNIs)(n=125)]and non-sirolimus group[patients took CNI-based therapy without sirolimus(n=68)].Recurrence-free survival(RFS)and overall survival(OS)were compared between the two groups.The prognostic factors and independent risk factors for RFS and OS were further evaluated.Results:Non-sirolimus was an independent risk factor for RFS(HR=2.990;95%CI:1.050-8.470;P=0.040)and OS(HR=3.100;95%CI:1.190-8.000;P=0.020).A higher proportion of patients beyond Hangzhou criteria was divided into the sirolimus group(69.6%vs.80.9%,P=0.030).Compared with the non-sirolimus group,the sirolimus group had significantly better RFS(P<0.001)and OS(P<0.001).Further subgroup analysis showed similar results.Conclusions:This study demonstrated that sirolimus significantly decreased HCC recurrence and prolonged RFS and OS in LT patients with different stage of HCC.

Pregnancy complicated by juxtaglomerular cell tumor of the kidney:A case report

BACKGROUND Juxtaglomerular cell tumor(JGCT)of the kidney,also known as reninoma,is a rare renal tumor that typically clinically manifests as hypertension,hypokalemia,high renin,and high aldosterone.It is a cause of secondary hypertension.Pregnancy with JGCT is rarer and easily misdiagnosed as pregnancy-induced hypertension,thus affecting treatment.CASE SUMMARY A 28-year-old woman presented in early pregnancy with hypertension(blood pressure of 229/159 mmHg),nausea,and occasional dizziness and headache.The patient was diagnosed with pregnancy-induced hypertension,and no relief was found after symptomatic treatment;hence,the pregnancy was terminated by artificial abortion.Her blood pressure remained high following termination of pregnancy.Blood tests suggested hypokalemia(2.997 mmol/L),blood aldo-sterone measured 613 ng/L,and computed tomography urography showed a tumor in the right kidney.Therefore,laparoscopic partial nephrectomy was performed.After surgery,the patient’s blood pressure returned to normal,and blood potassium,aldosterone,and renin normalized.Postoperative pathological examination revealed JGCT.After long-term follow-up,the patient became pregnant again 6 mo after surgery.No hypertension occurred during pregnancy,and the patient delivered a healthy female neonate.CONCLUSION Patients with pregnancy complicated by JGCT are difficult to diagnose.Herein,we advise surgeons on proper handling of such situations.

Gut Microbiota Modulation:A Viable Strategy to Address Medical Needs in Hepatocellular Carcinoma and Liver Transplantation

Hepatocellular carcinoma(HCC)is the most common malignancy of the liver,posing a significant threat to public health.Although liver transplantation(LT)is an effective treatment for HCC,ischemia–reperfusion(I/R)injury,transplant rejection,and complications after LT can greatly reduce its effectiveness.In recent years,transplant oncology has come into being,a comprehensive discipline formed by the intersection and integration of surgery,oncology,immunology,and other related disciplines.Gut microbiota,an emerging field of research,also plays a crucial role.Through the microbiome–gut–liver axis,the gut microbiota has an impact on the onset and progression of HCC as well as LT.This review summarizes the mechanisms by which the gut microbiota affects HCC and its bidirectional interactions with chronic liver disease that can develop into HCC as well as the diagnostic and prognostic value of the gut microbiota in HCC.In addition,gut microbiota alterations after LT were reviewed,and the relationship between the gut microbiota and liver I/R injury,the efficacy of immunosuppressive drugs used,and complications after LT were discussed.In the era of LT oncology,the role of the gut microbiota in HCC and LT should be emphasized,which can provide new insights into the management of HCC and LT via gut microbiota modulation.

Older liver grafts from donation after circulatory death are associated with impaired survival and higher incidence of biliary non-anastomotic structure

Background:Grafts from older donors after circulatory death were associated with inferior outcome in liver transplants in the past.But it has seemed to remain controversial in the last decade,as a result of modified clinical protocols,selected recipients,and advanced technology of organ perfusion and preservation.The present study aimed to examine the impact of older donor age on complications and survival of liver transplant using grafts from donation after circulatory death(DCD).Methods:A total of 944 patients who received DCD liver transplantation from 2015 to 2020 were included and divided into two groups:using graft from older donor(aged≥65 years,n=87)and younger donor(age<65 years,n=857).Propensity score matching(PSM)was applied to eliminate selection bias.Results:A progressively increased proportion of liver transplants with grafts from older donors was observed from 1.68%to 15.44%during the study period.The well-balanced older donor(n=79)and younger donor(n=79)were 1:1 matched.There were significantly more episodes of biliary nonanastomotic stricture(NAS)in the older donor group than the younger donor group[15/79(19.0%)vs.6/79(7.6%);P=0.017].The difference did not reach statistical significance regarding early allograft dysfunction(EAD)and primary non-function(PNF).Older livers had a trend toward inferior 1-,2-,3-year graft and overall survival compared with younger livers,but these differences were not statistically significant(63.1%,57.6%,57.6%vs.76.9%,70.2%,67.7%,P=0.112;64.4%,58.6%,58.6%vs.76.9%,72.2%,72.2%,P=0.064).The only risk factor for poor survival was ABO incompatible transplant(P=0.008)in the older donor group.In the subgroup of ABO incompatible cases,it demonstrated a significant difference in the rate of NAS between the older donor group and the younger donor group[6/8(75.0%)vs.3/14(21.4%);P=0.014].Conclusions:Transplants with grafts from older donors(aged≥65 years)after circulatory death are more frequently associated with inferior outcome compared to those from younger donors.Older grafts from DCD are more likely to develop NAS,especially in ABO incompatible cases.

Whole-brain CT Perfusion at Admission and During Delayed Time-window Detects the Delayed Cerebral Ischemia in Patients with Aneurysmal Subarachnoid Hemorrhage

Objective To evaluate the utility of computed tomography perfusion(CTP)both at admission and during delayed cerebral ischemia time-window(DCITW)in the detection of delayed cerebral ischemia(DCI)and the change in CTP parameters from admission to DCITW following aneurysmal subarachnoid hemorrhage.Methods Eighty patients underwent CTP at admission and during DCITW.The mean and extreme values of all CTP parameters at admission and during DCITW were compared between the DCI group and non-DCI group,and comparisons were also made between admission and DCITW within each group.The qualitative color-coded perfusion maps were recorded.Finally,the relationship between CTP parameters and DCI was assessed by receiver operating characteristic(ROC)analyses.Results With the exception of cerebral blood volume(P=0.295,admission;P=0.682,DCITW),there were significant differences in the mean quantitative CTP parameters between DCI and non-DCI patients both at admission and during DCITW.In the DCI group,the extreme parameters were significantly different between admission and DCITW.The DCI group also showed a deteriorative trend in the qualitative color-coded perfusion maps.For the detection of DCI,mean transit time to the center of the impulse response function(Tmax)at admission and mean time to start(TTS)during DCITW had the largest area under curve(AUC),0.698 and 0.789,respectively.Conclusion Whole-brain CTP can predict the occurrence of DCI at admission and diagnose DCI during DCITW.The extreme quantitative parameters and qualitative color-coded perfusion maps can better reflect the perfusion changes of patients with DCI from admission to DCITW.

Prognostic implication of early posttransplant hypercholesterolemia in liver transplantation for patients with hepatocellular carcinoma

Background: Hyperlipidemia is a common complication after liver transplantation(LT) and develops mostly in the early posttransplant period. Recently, some studies have reported a positive correlation between hyperlipidemia and favorable prognosis in patients with hepatocellular carcinoma(HCC) undergoing hepatectomy. This study aimed to evaluate the possibility of predicting prognosis in HCC patients receiving LT by early posttransplant dyslipidemia. Methods: From January 2015 to December 2017, a total of 806 HCC patients from China Liver Transplant Registry database were retrospectively enrolled. The prognostic relevance of early posttransplant hypertriglyceridemia or hypercholesterolemia was examined using survival analysis, and subgroup analysis was implemented based on LT criteria. Results: Early posttransplant hypercholesterolemia(EPHC) was independently inversely associated with the risk of recurrence [hazard ratio(HR) = 0.630;P = 0.022], but was not significantly correlated with the mortality. However, early posttransplant hypertriglyceridemia was not related to prognosis. Intriguingly, with further classification, we found that borderline EPHC(B-EPHC), instead of significant EPHC, was a predictor of lower risk for both recurrence(HR = 0.504;P = 0.006) and mortality(HR = 0.511;P = 0.023). Compared with non-EPHC patients, B-EPHC patients achieved significantly superior 1-year and 3-year tumor-free survival(89.6% and 83.7% vs. 83.8% and 72.7% respectively;P = 0.023), and 1-year and 3-year overall survival(95.8% and 84.8% vs. 94.6% and 77.6% respectively;P = 0.039). In the subgroup analysis, BEPHC remained an independent predictor of better prognosis in patients beyond Milan criteria and those within Hangzhou criteria;whereas there was no significant relationship between B-EPHC and prognosis in patients within Milan criteria and those beyond Hangzhou criteria. More interestingly, patients beyond Milan criteria but within Hangzhou criteria were identified as the crucial subpopulation who benefited from B-EPHC(recurrence HR = 0.306, P = 0.011;mortality HR = 0.325, P = 0.031).Conclusions: B-EPHC could assist transplant teams in dynamically evaluating prognosis after LT for HCC as a postoperative non-oncological biomarker, especially in patients beyond Milan criteria but within Hangzhou criteria.

Pyogenic spondylitis caused by Escherichia coli: A case report and literature review

BACKGROUND Pyogenic spondylitis is often manifested as atypical low back pain and fever,which makes it easy to be confused with other diseases.Here we report a case of pyogenic spondylitis and describe the diagnosis and treatment based on the related literature.CASE SUMMARY The reported case suffered from pyogenic spondylitis caused by Escherichia coli and complicated with bacteremia and psoas abscess.Acute pyelonephritis was initially diagnosed due to atypical symptoms.Symptoms were improved from antibiotic treatment while developing progressive lower limb dysfunction.One month post the admission,the patient underwent anterior lumbar debridement+autogenous iliac bone graft fusion+posterior percutaneous screw-rod internal fixation,and received 6 wk of antibiotic treatment after the operation.Reexamination 4 mo post the operation showed that the patient had no evident pain in the waist,and walked well with no evident dysfunction of lower limbs.CONCLUSION Here we describe the application value of several imaging examinations,such as X-ray,computed tomography and magnetic resonance imaging,and certain tests like erythrocyte sedimentation rate and C-reactive protein in the clinical treatment of pyogenic spondylitis.This disease requires early diagnosis and treatment.Sensitive antibiotics should be used in early stages and surgical intervention should be taken if necessary,which may help for a speedy recovery and prevent the occurrence of severe complications.

Efficacy and safety of anlotinib as an adjuvant therapy in hepatocellular carcinoma patients with a high risk of postoperative recurrence

Objective:Hepatocellular carcinoma(HCC)has a high rate of postoperative recurrence and lacks an effective treatment to prevent recurrence.This study aims to investigate the efficacy and safety of anlotinib in postoperative adjuvant therapy for HCC patients with high-risk recurrence factors.Methods:For this multicenter,retrospective study,we recruited 63 HCC patients who received either anlotinib(n=27)or transcatheter arterial chemoembolization(TACE)(n=36)from six research centers in China between March 2019 and October 2020.The primary endpoint was disease-free survival(DFS)and the secondary endpoints were overall survival(OS)and safety.Results:In this study,the median follow-up time was 25.9 and 26.8 months in the anlotinib and TACE groups,respectively.There was no significant difference in the median DFS between the anlotinib[26.8 months,95%confidence interval(95%CI):6.8-NE]and TACE groups(20.6 months,95%CI:8.4-NE).The 12-month OS rates in the anlotinib and TACE groups were 96.3%and 97.2%,respectively.In the anlotinib group,19 of 27patients(70.4%)experienced treatment-emergent adverse events,with the most common events(≥10%)being hypertension(22.2%)and decreased platelet count(22.2%).Conclusions:The results indicate that anlotinib,as a new,orally administered tyrosine kinase inhibitor,has the same efficacy as TACE,and side effects can be well controlled.

Total removal of a large esophageal schwannoma by submucosal tunneling endoscopic resection:A case report and review of literature

BACKGROUND Primary schwannoma is a rare submucosal tumor of the esophagus,which is most often benign,and surgery is the only effective treatment.So far,only a few cases have been reported.Herein,we reported a single case diagnosed with primary esophageal schwannoma that was totally removed by submucosal tunneling endoscopic resection(STER).CASE SUMMARY A 62-year-old man presented to the hospital with a history of resection of a malignant gastric tumor and mild dysphagia.Endoscopic examination revealed a large submucosal elevated lesion in the esophagus 25-30 cm from the incisors.Endoscopic ultrasonography detected a 45 mm×35 mm×31 mm hypoechoic lesion;chest computed tomography showed a mass of approximately 55 mm×35 mm×29 mm.A preliminary examination showed features suggestive of a stromal tumor.Pathological findings indicated esophageal schwannoma.Next,STER alone was performed to completely resect the mass,and the patient recovered well post-surgery.Afterward,the patient was discharged and showed no tumor recurrence at 33 mo of follow-up.CONCLUSION Endoscopic resection is still an effective treatment for large esophageal schwannomas(>30 mm)under meticulous morphological evaluation.

Imaging features of retinal hemangioblastoma:A case report

BACKGROUND Hemangioblastoma typically occurs in the cerebellum,spinal cord,and central nervous system.However,in rare cases,it could occur in the retina or optic nerve.The prevalence of retinal hemangioblastoma is 1 in 73080,and it occurs either alone or as the manifestation of von Hippel Lindau(VHL)disease.Here,we reported a rare case with the imaging features of retinal hemangioblastoma without VHL syndrome,along with the relevant literature review.CASE SUMMARY A 53-year-old man had progressive swelling,pain and blurred vision in the left eye without obvious inducement for 15 d.Ultrasonography revealed a possible optic nerve head melanoma.Computed tomography(CT)showed punctate calcification on the posterior wall of the left eye ring and small patchy soft tissue density in the posterior part of the eyeball.Magnetic resonance imaging showed slightly hyperintense signal on T1-weighted images and slightly hypointense-toisointense signal on T2-weighted images at the medial and posterior edges of the left eyeball,a significant enhancement was observed in the contrast-enhanced scans.Positron emission tomography/CT fusion images showed that the glucose metabolism of the lesion was normal.Pathology was consistent with hemangioblastoma.CONCLUSION Early identification of retinal hemangioblastoma based on imaging features is of great value for its personalized treatment.

Effects of health concept model-based detailed behavioral care on mood and quality of life in elderly patients with chronic heart failure

BACKGROUND With the intensification of social aging,the susceptibility of the elderly population to diseases has attracted increasing attention,especially chronic heart failure(CHF)that accounts for a large proportion of the elderly.AIM To evaluate the application value of health concept model-based detailed behavioral care in elderly patients with CHF.METHODS This study recruited 116 elderly CHF patients admitted from October 2018 to October 2020 and grouped them according to the nursing care that they received.The elderly patients who underwent health concept model-based detailed behavioral care were included in a study group(SG;n=62),and those who underwent routine detailed behavioral nursing intervention were included as a control group(CG;n=54).Patients’negative emotions(NEs),quality of life(QoL),and nutritional status were assessed using the self-rating anxiety/depression scale(SAS/SDS),the Minnesota Living with Heart Failure Questionnaire(MLHFQ),and the Modified Quantitative Subjective Global Assessment(MQSGA)of nutrition,respectively.Differences in rehabilitation efficiency,NEs,cardiac function(CF)indexes,nutritional status,QoL,and nursing satisfaction were comparatively analyzed.RESULTS A higher response rate was recorded in the SG vs the CG after intervention(P<0.05).After care,the left ventricular ejection fraction was higher while the left ventricular end-diastolic dimension and left ventricular end systolic diameter were lower in the SG compared with the CG(P<0.05).The post-intervention SAS and SDS scores,as well as MQSGA and MLHFQ scores,were also lower in the SG(P<0.05).The SG was also superior to the CG in the overall nursing satisfaction rate(P<0.05).CONCLUSION Health concept model-based detailed behavioral care has high application value in the nursing care of elderly CHF patients,and it can not only effectively enhance rehabilitation efficiency,but also mitigate patients’NEs and improve their CF and QoL.

Tripartite intensive intervention for prevention of rebleeding in elderly patients with hypertensive cerebral hemorrhage

BACKGROUND Hypertensive cerebral hemorrhage(HICH)is the rupture and bleeding of vessels of the cerebral parenchyma caused by continuously elevated or violently fluctuating blood pressure.The condition is characterized by high disability and high mortality.Hematoma formation and resulting space-occupying effects following intracerebral hemorrhage are among the key causes of impaired neurological function and disability.Consequently,minimally invasive clearance of the hematoma is undertaken for the treatment of HICH because it can effectively relieve intracranial hypertension.Therefore,special attention should be given to the quality of medical and nursing interventions in the convalescent period after minimally invasive hematoma clearance.AIM The study aim was to determine the value of intensive intervention,including doctors,nurses,and patient families,for the prevention of rebleeding in elderly patients with HICH during the first hospitalization for rehabilitation after the ictal event METHODS A total of 150 elderly HICH patients with minimally invasive hematoma evacuation in our hospital between May 2018 and May 2020 were selected and equally divided into two groups of 75 each by their planned intervention.The control group was given conventional nursing intervention and the observation group was given tripartite intensive intervention.The length of hospital stay,cost,complication rate,satisfaction rate,and rebleeding rate during hospitalization were recorded.Changes in cerebral blood flow indicators were recorded in both groups.Changes in the National Institutes of Health Stroke Scale(NIHSS)score,quality of life index(QLI)score,and health behavior score were evaluated at the National Institutes of Health.RESULTS Duration of hospitalization was shorter in the in the observation group than in the control group,the hospitalization cost was less than in the control group,and the rate of rebleeding during hospitalization was lower than in the control group(all P<0.05).There were no significant differences between the two groups before treatment(all P>0.05).The mean flow rate(Qmean)and mean velocity(Vmean)of the two groups increased(P<0.05),and the dynamic resistance and peripheral resistance decreased(P<0.05).The Qmean and Vmean in the intervention group were higher than those in the control group(P<0.05).Moreover,the dynamic resistance and peripheral resistance of the blood vessels were also lower in the intervention group than in the control group(P<0.05).The difference in health behavior scores between the two groups before treatment was not significant(P>0.05).In both groups,the scores for healthy behaviors such as emotion control,medication adherence,dietary management,exercise management,and selfmonitoring were higher after than before treatment(P<0.05),and the scores of healthy behaviors in the intervention group were higher than those in the control group(P<0.05).There was no significant difference in the NIHSS and QLI scores between the two groups before treatment(P>0.05).The QLI scores of the two groups increased(P<0.05),and the NIHSS scores decreased(P<0.05).The QLI scores of the intervention group were higher than those of the control group(P<0.05),and the NIHSS score was correspondingly lower than that of the control group(P<0.05).The incidence of respiratory infections,pressure sores,central hyperpyrexia,and deep venous thrombosis was lower in the intervention group than in the control group.Accordingly,the satisfaction rate was higher in the treatment group than that in the control group(P<0.05).CONCLUSION Intensive intervention by doctors,nurses,and families of elderly patients with HICH reduced the rate of rebleeding during hospitalization.It also reduced the incidence of complications,promoted rehabilitation,improved the quality of life,and enhanced nerve function.Additionally,it improved satisfaction and promoted healthy behaviors.

Rare variant of pancreaticobiliary maljunction associated with pancreas divisum in a child diagnosed and treated by endoscopic retrograde cholangiopancreatography: A case report

BACKGROUND Pancreaticobiliary maljunction(PBM) is an uncommon congenital anomaly of the pancreatic and biliary ductal system, defined as a union of the pancreatic and biliary ducts located outside the duodenal wall. According to the Komi classification of PBM, the common bile duct(CBD) directly fuses with the ventral pancreatic duct in all types. Pancreas divisum(PD) occurs when the ventral and dorsal ducts of the embryonic pancreas fail to fuse during the second month of fetal development. The coexistence of PBM and PD is an infrequent condition.Here, we report an unusual variant of PBM associated with PD in a pediatric patient, in whom an anomalous communication existed between the CBD and dorsal pancreatic duct.CASE SUMMARY A boy aged 4 years and 2 mo was hospitalized for abdominal pain with nausea and jaundice for 5 d. Abdominal ultrasound showed cholecystitis with cholestasis in the gallbladder, dilated middle-upper CBD, and a strong echo in the lower CBD, indicating biliary stones. The diagnosis was extrahepatic biliary obstruction caused by biliary stones, which is an indication for endoscopic retrograde cholangiopancreatography(ERCP). ERCP was performed to remove biliary stones. During the ERCP, we found a rare communication between the CBD and dorsal pancreatic duct. After clearing the CBD with a balloon, an 8.5 Fr 4-cm pigtail plastic pancreatic stent was placed in the biliary duct through the major papilla. Six months later, his biliary stent was removed after he had no symptoms and normal laboratory tests. In the following 4-year period, the child grew up normally with no more attacks of abdominal pain.CONCLUSION We consider that ERCP is effective and safe in pediatric patients with PBM combined with PD, and can be the initial therapy to manage such cases,especially when it is combined with aberrant communication between the CBD and dorsal pancreatic duct.

Biomaterials reinforced MSCs transplantation for spinal cord injury repair

Due to the complex pathophysiological mechanism, spinal cord injury (SCI) has become one of the most intractable central nervous system (CNS) diseases to therapy. Stem cell transplantation, mesenchymal stem cells (MSCs) particularly, appeals to more and more attention along with the encouraging therapeutic results for the functional regeneration of SCI. However, traditional cell transplantation strategies have some limitations, including the unsatisfying survival rate of MSCs and their random diffusion from the injection site to ambient tissues. The application of biomaterials in tissue engineering provides a new horizon. Biomaterials can not only confine MSCs in the injured lesions with higher cell viability, but also promote their therapeutic efficacy. This review summarizes the strategies and advantages of biomaterials reinforced MSCs transplantation to treat SCI in recent years,which are clarified in the light of various therapeutic effects in pathophysiological aspects of SCI.
