An interpretability model for syndrome differentiation of HBV-ACLF in traditional Chinese medicine using small-sample imbalanced data

Objective Clinical medical record data associated with hepatitis B-related acute-on-chronic liver failure(HBV-ACLF)generally have small sample sizes and a class imbalance.However,most machine learning models are designed based on balanced data and lack interpretability.This study aimed to propose a traditional Chinese medicine(TCM)diagnostic model for HBV-ACLF based on the TCM syndrome differentiation and treatment theory,which is clinically interpretable and highly accurate.Methods We collected medical records from 261 patients diagnosed with HBV-ACLF,including three syndromes:Yang jaundice(214 cases),Yang-Yin jaundice(41 cases),and Yin jaundice(6 cases).To avoid overfitting of the machine learning model,we excluded the cases of Yin jaundice.After data standardization and cleaning,we obtained 255 relevant medical records of Yang jaundice and Yang-Yin jaundice.To address the class imbalance issue,we employed the oversampling method and five machine learning methods,including logistic regression(LR),support vector machine(SVM),decision tree(DT),random forest(RF),and extreme gradient boosting(XGBoost)to construct the syndrome diagnosis models.This study used precision,F1 score,the area under the receiver operating characteristic(ROC)curve(AUC),and accuracy as model evaluation metrics.The model with the best classification performance was selected to extract the diagnostic rule,and its clinical significance was thoroughly analyzed.Furthermore,we proposed a novel multiple-round stable rule extraction(MRSRE)method to obtain a stable rule set of features that can exhibit the model’s clinical interpretability.Results The precision of the five machine learning models built using oversampled balanced data exceeded 0.90.Among these models,the accuracy of RF classification of syndrome types was 0.92,and the mean F1 scores of the two categories of Yang jaundice and Yang-Yin jaundice were 0.93 and 0.94,respectively.Additionally,the AUC was 0.98.The extraction rules of the RF syndrome differentiation model based on the MRSRE method revealed that the common features of Yang jaundice and Yang-Yin jaundice were wiry pulse,yellowing of the urine,skin,and eyes,normal tongue body,healthy sublingual vessel,nausea,oil loathing,and poor appetite.The main features of Yang jaundice were a red tongue body and thickened sublingual vessels,whereas those of Yang-Yin jaundice were a dark tongue body,pale white tongue body,white tongue coating,lack of strength,slippery pulse,light red tongue body,slimy tongue coating,and abdominal distension.This is aligned with the classifications made by TCM experts based on TCM syndrome differentiation and treatment theory.Conclusion Our model can be utilized for differentiating HBV-ACLF syndromes,which has the potential to be applied to generate other clinically interpretable models with high accuracy on clinical data characterized by small sample sizes and a class imbalance.

Prognostic significance of identification of traditional Chinese medicine syndromes in colorectal cancer

Background:Traditional Chinese medicine(TCM)syndrome is the basic unit of TCM treatment,which help clinicians assess the disease progression and treatment preoperative of tumor patients.However,the prognostic significance of TCM syndrome is still unclear.This study aims to detect the differences in overall survival between different TCM syndrome and further develop a new nomogram with TCM syndrome for predicting overall survival in colorectal cancer.Methods:A total of 324 patients with colorectal cancer were enrolled and categorized into three groups based on TCM syndrome:deficiency,excess,and deficiency-excess.The prognosis of colorectal cancer patients with different TCM syndromes was evaluated using Kaplan-Meier analysis and Cox regression analysis.Results:The proportion of advanced stage and lymph metastasis in the patients with deficiency syndrome was higher,and the overall survival was shorter than other syndromes.Meanwhile,the TCM syndrome(P<0.001),tumor invasion depth(P<0.001),lymph metastasis(P=0.018),organic metastasis(P=0.005)and tumor node metastasis(TNM)stage(P=0.029)were the independent prognostic factor.Then,a new nomogram with TCM syndrome was established and assessed.324 colorectal cancer patients were randomly divided into training(n=215)and validation cohorts(n=109).A nomogram incorporating preoperative TCM syndrome,gender,age,T,N,and M status was developed,which had good discrimination and calibration.Conclusion:Taken together,our results indicated that TCM syndrome could assess the prognosis of colorectal cancer.The nomogram incorporating TCM syndromes and tumor information is helpful for risk stratification and prognostic predictions in colorectal cancer preoperatively.

Traditional Chinese medicine for foot pain in a patient with complex regional pain syndrome: A case report

BACKGROUND Complex regional pain syndrome(CRPS)is characterized by pain as well as sensory,motor,and sudomotor disorders.Generally,it is classified into two types CRPS-I and CRPS-II.There is no single diagnostic test or treatment approach for CRPS,and a multidisciplinary approach is gaining attention to improve patients’symptoms and their quality of life.CASE SUMMARY A 35-year-old woman with an unremarkable medical history sought treatment for CRPS at a hospital of Korean medicine.During her first visit,she was wheelchairbound due to severe pain in her left lower extremity.She had edema and discoloration of the left foot.She was treated with a combination of traditional Chinese medicine(TCM)approaches,including acupuncture,moxibustion,pharmacopuncture,and herbal decoction,for approximately 20 sessions.The foot and ankle outcome score(FAOS)and visual analog scale(VAS)score for pain were evaluated,along with general signs and functions.Her symptoms,signs,FAOS,and VAS scores improved after treatment,with a significant 7-degree decrease in the VAS score and a 62-point increase in the FAOS score.Additionally,the foot swelling and discoloration gradually resolved.During the phone follow-up,5 mo after the last visit,additional improvements in outcomes were observed.CONCLUSION Combined TCM treatment may be a reasonable and safe option for alleviating symptoms and improving function in patients with CRPS.

Nursing outcomes of traditional Chinese medicine adjunctive therapy on osteofascial compartment syndrome:a review

The rate of disability due to acute osteofascial compartment syndrome(OCS)is high,and the therapeutic effect of decompressive fasciotomy is not ideal.This paper retrospectively reviews the modern treatment of OCS,including Western medicine and Traditional Chinese medicine(TCM),mainly in the context of the advantages of TCM in the treatment process of decompressive fasciotomy or conservative treatment to the patients who are suffering from OCS.It was found that TCM treatment reduced the levels of serum creatine kinase(CK),lactate dehydrogenase(LDH),and aspartate aminotransferase(AST);it is beneficial to the elimination of swelling and pain.TCM adjunctive therapy promotes patients’postoperative functional recovery and decreases the occurrence of fasciotomy in patients;TCM can relieve tissue hypoxia of compartments and prevent necrosis of muscle and nerve tissue.TCM treatment improves the quality of medical service and ensures the safety of OCS patients.This paper aims to summarize the function of TCM in the treatment of OCS,provide reference for the clinical treatment of OCS,and improve the nursing/medical outcomes of OCS.

Research Survey of Animal Model of Hepatic Fibro-sis Integrated with Western Medicine Diseases and Traditional Chinese Medicine^TCM~)Syndrome

Although the animal models of hepatic fibrosis developed by former researchers have pathological changes of hepatic fibrosis, they do not include charac- teristics of important TCM syndromes such as stagnation of qi, deficiency of qi, liver depression, phlegm-dampness and blood stasis because of single-factor model- ing. Animal models of hepatic fibrosis and animal models integrated disease and syndrome were reviewed, and several new types of integrated disease and syndrome animal models constructed by multiple-factor modeling method were evaluated, under the guidance of etiological theory of TCM. This kind of hepatic fibrosis model animals has dual characteristics of disease and syndrome. It is consistent with pathological characteristics of hepatic fibrosis in western medicine when replicating the basic characteristics accorded with TCM syndrome. Thus, the pathogenesis and pathogenic process of clinical disease and syndrome formation is simulated more ac- curately, providing a new platform and pathway for studying hepatic fibrosis disease with integrated traditional Chinese and western medicine.

Investigation on the cognitive status and the infiltration path of Traditional Chinese Medicine among residents in Liaoning Province

To understand citizens’awareness,trust and attitude towards Tradition Chinese medicine(TCM),to seek the best penetration path of TCM products and culture,to analyze their influencing factors,and to provide suggestions and countermeasures,a non-probabilistic judgment sampling method was used to conduct a survey among 459 people online with the help of Questionnaire Star and 434 valid questionnaires were collected.The survey shows that residents have a high degree of recognition and identification of Chinese medicine;citizens are rational when choosing TCM products,and the recognition of the emerging TCM culture infiltration path is low.Different social and demographic factors affect citizens’awareness,trust and attitude towards TCM,as well as the choice of infiltration path(P<0.05).

Gut microbiota contributes to the distinction between two traditional Chinese medicine syndromes of ulcerative colitis

BACKGROUND Ulcerative colitis(UC)is considered to be closely associated with alteration of intestinal microorganisms.According to the traditional Chinese medicine(TCM)theory,UC can be divided into two disease syndromes called Pi-Xu-Shi-Yun(PXSY)and Da-Chang-Shi-Re(DCSR).The relationships among gut microbiota,TCM syndromes,and UC pathogenesis have not been well investigated.AIM To investigate the role of gut microbiota in UC and the distinction of microbiota dysbiosis between PXSY and DCSR syndromes.METHODS From May 2015 to February 2016,UC patients presenting to LongHua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study.Fresh stool specimens of UC patients with PXSY or DCSR were collected.The feces of the control group came from the health examination population of Longhua Hospital.The composition of gut bacterial communities in stool samples was determined by the pyrosequencing of 16S ribosomal RNA.The high-throughput sequencing reads were processed with QIIME,and biological functions were predicted using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States.RESULTS The composition of gut bacterial communities in 93 stool samples(30 healthy controls,32 patients with PXSY syndrome,and 31 patients with DCSR syndrome)was determined by the pyrosequencing of 16S ribosomal RNA.Beta diversity showed that the composition of the microbiota was different among the three groups.At the family level,Porphyromonadaceae,Rikeneliaceae,and Lachnospiraceae significantly decreased while Enterococcus,Streptococcus,and other potential pathogens significantly increased in UC patients compared to healthy subjects.At the genus level,Parabacteroides,Dorea,and Ruminococcus decreased while Faeca-libacterium showed increased abundance in UC compared to healthy controls.Five differential taxa were identified between PXSY and DCSR syndromes.At the genus level,a significantly increased abundance of Streptococcus was observed in DCSR patients,while Lachnoclostridium increased in PXSY patients.The differential functional pathways of the gut microbiome between the PXSY and DCSR groups mainly included lipid metabolism,immunity,and the metabolism of polypeptides.CONCLUSION Our study suggests that the gut microbiota contributes to the distinction between the two TCM syndromes of UC.

Treatment of abdominal compartment syndrome in severe acute pancreatitis patients with traditional Chinese medicine

AIM: To investigate the therapeutic effect of traditional Chinese traditional medicines Da Cheng Qi Decoction (Timely-Purging and Yin-Preserving Decoction) and Glauber's salt combined with conservative measures on abdominal compartment syndrome (ACS) in severe acute pancreatitis (SAP) patients. METHODS: Eighty consecutive SAP patients, admitted for routine non-operative conservative treatment, were randomly divided into study group and control group (40 patients in each group). Patients in the study group received Da Cheng Qi Decoction enema for 2 h and external use of Glauber's salt, once a day for 7 d. Patients in the control group received normal saline (NS) enema. Routine non-operative conservative treatments included non-per os nutrition (NPON), gastrointestinal decompression, life support, total parenteral nutrition (TPN), continuous peripancreatic vascular pharmaceutical infusion and drug therapy. Intra-cystic pressure (ICP) of the two groups was measured during treatment. The effectiveness and outcomes of treatment were observed and APACHE Ⅱ scores were applied in analysis. RESULTS: On days 4 and 5 of treatment, the ICP was lower in the study group than in the control group(P < 0.05). On days 3-5 of treatment, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores for the study and control groups were significantly different (P < 0.05). Both the effectiveness and outcome of the treatment with Da Cheng Qi Decoction on abdominalgia, burbulence relief time, ascites quantity, cyst formation rate and hospitalization time were quite different between the two groups (P < 0.05). The mortality rate for the two groups had no significant difference. CONCLUSION: Da Cheng Qi Decoction enema and external use of Glauber's salt combined with routine non-operative conservative treatment can decrease the intra-abdominal pressure (IAP) of SAP patients and have preventive and therapeutic effects on abdominal compartment syndrome of SAP.

Epigastric pain syndrome: What can traditional Chinese medicine do? A randomized controlled trial of Biling Weitong Granules

BACKGROUND Recent research suggests that although prokinetic agents,acid suppressors,and radical treatment for Helicobacter pylori infection may be effective in patients with functional dyspepsia(FD),a large proportion of patients still fail to respond to these treatments or may suffer from severe adverse reactions.Many traditional Chinese medicinal herbs can regulate the status of the entire body and have special advantages in the treatment of functional diseases.The present study was designed to verify the efficacy of Biling Weitong Granules(BLWTG),a traditional Chinese medicinal herbal compound formula,in alleviating epigastric pain syndrome(EPS)in FD patients,in an attempt to provide an effective prescription for the clinical treatment of this disease.AIM To evaluate the clinical efficacy and safety of BLWTG in treating EPS in patients with FD.METHODS In this multicenter,stratified,randomized,double-blind,placebo-controlled,parallel group clinical trial,eligible patients were randomized into the BLWTG and placebo groups who were treated for 6 wk.Efficacy indicators including the severity and frequency of EPS and the time to pain resolution and safety indicators including adverse events were observed and compared.RESULTS The baseline demographic data and clinical characteristics,such as epigastric pain symptoms,pain intensity,and frequency of attacks,were matched between the two groups before randomization.After 6 wk of treatment and after the center effect was eliminated,the epigastric pain was significantly improved in 28.33%and 85.59%of the patients in the placebo and BLWTG groups,respectively(P<0.05).At 6 wk,the resolution rate of epigastric pain was 15%and 69.49%in the placebo and BLWTG groups,respectively(P<0.05).The differences of total FD clinical score between these two groups were significant(P<0.05)at 2,4,and 6 wk(P<0.05).The scores of each item and the total score in the Functional Digestive Disorders Quality of Life Questionnaire showed significant differences between the two groups at 6 wk after both the center and interaction effects were eliminated(P<0.05).There was no significant difference in the incidence of adverse events between the two groups,and no serious adverse event was noted during the observation.CONCLUSION Compared with placebo,BLWTG markedly improved EPS in FD patients without causing serious adverse reactions.

Syndrome differentiation in traditional Chinese medicine and E-cadherin/ICAM-1 gene protein expression in gastric carcinoma

AIM： To explore the syndrome differentiation in traditional Chinese medicine （TCM） and gene protein expression in gastric carcinoma METHODS： Preoperative data of gastric cancer cases were collected from the General Surgery Department and classified according to the criteria for syndrome differentiation in TCM. E-cadherin （E-cad） and ICAM-1 gene protein expressions were detected in postoperative specimens from these cases by the immunohistochemical EnVision two-step method. RESULTS： The E-cad positive expression rate was 90% in 100 cases of gastric carcinoma. The difference in E-cad expression was significant between the different syndrome differentiation types in TCM （P 〈 0.01）. Further group-group comparison showed that there was a significant difference in E-cad expression between the stagnation of phlegm-damp type and the deficiency in both qi and blood and the deficiency-cold of stomach and spleen types, where E-cad expression was high. There was no significant difference between the internal obstruction of stagnant toxin type and the in-coordination between liver and stomach type, where E-cad expression was relatively low. The ICAM-1 positive expression rate was 58%, and there was no statistically significant difference between the two groups （x^2= 8.999, P 〉 0.05）. CONCLUSION： E-cad expression is relatively low in the internal obstruction of stagnant toxin type and the incoordination between liver and stomach type, where tumor development and metastasis may be associated with low E-cad expression, or with low homogeneous adhesiveness between tumor cells.

Traditional Chinese medicine syndromes of chronic hepatitis B with precore mutant

ABM: This study aims at exploring the distribution of TCM syndromes in CHB patients with HBV pre-core mutation (1896) and the relationship between pre-core mutation and T lymphocytes subgroup, through which to provide objective data on clinical syndrome differentiation of TCM, and further to suggest the therapeutic principle and guide clinical treatment. METHODS: One hundred and forty CHB patients were evenly divided into two study groups, HBV pre-core mutant group and HBV pre-core wild-type group. Besides, 30 healthy blood donors were selected as a healthy control group. HBV-labeled compound, T lymphocytes subgroup, and HBV-DNA pre-core mutant were tested in the study groups. T lymphocytes subgroup were also tested in the control group. All the patients were both diagnosed by syndrome differentiation of TCM and western medicine. RESULTS: The most common syndrome in mutant group was damp-heat combined with blood stasis, and the most common syndrome in the wild-type group was damp-heat stasis in the middle-jiao. There were more cases of medium and severe hepatitis in mutant group than that in wild-type group. The content of CD4+ lymphocytes and CD4+/CD8+ ratio were decreased gradually (healthy control group>wild-type group>mutant group). In the wild-type group, severe and medium CHB patients had considerably lower level of them than mild CHB patients. However, in the mutant group, the opposite result appeared. Meanwhile, the content of HBV-DNA in mutant group was higher than that in wild-type group. CONCLUSION: Damp, heat, toxin and blood stasis were the basic pathogens of CHB, whether pre-core mutant or not. CHB with precore mutant may lead to more severe hepatitis. The decreased content of CD4+ lymphocytes and ratio of CD4+/CD8+ may be taken as one of the indices in confirming the deficiency syndrome of CHB patients with pre-core mutation.

Association between metabolic syndrome and body constitution of traditional Chinese medicine:A systematic review and meta-analysis

Background:The constitution theory of traditional Chinese medicine(TCM)states that body constitution and disease are associated;therefore,the identification of body constitution can provide reference for disease prevention and treatment.A series of clinical studies evaluating the association between TCM constitution and metabolic syndrome(MetS)have been conducted in recent years.The aim of this systematic review is to summarize and evaluate the clinical evidence of the relationship between constitution and MetS.Methods:The PubMed,Embase,China National Knowledge Infrastructure(CNKI),Chongqing VIP,and Wanfang Data electronic databases were searched from April 2009 to July 2020.The search terms included“metabolic syndrome,”“constitution,”and“Chinese medicine.”Observational studies evaluating the relationship between body constitution of TCM and MetS were included.The primary outcome included the distribution of constitutional types in the MetS population,and odds ratio(OR)or relative risk(RR)between constitution and MetS.Effect size was expressed as proportion or OR with 95%confidence interval(CI).Methodological quality of included studies was evaluated by the NewcastleeOttawa Scale(NOS)or the American Agency for Healthcare Research and Quality(AHRQ)criteria.Results:Three caseecontrol and 26 cross-sectional studies involving 30435 cases were included.Phlegm-dampness,qi-deficiency,and damp-heat were the main constitution types in patients with MetS,accounting for 29%(22%e39%),18%(13%e24%),and 12%(9%e17%)of the population,respectively;the risk of MetS in people with phlegm-dampness and qi-deficiency constitution was 1.74[1.27,2.38]and 1.29[1.01,1.65]times higher than that in those with other constitutions.There were sex-and age-related differences in the distribution of TCM constitution in patients with MetS.Conclusion:Phlegm-dampness and qi-deficiency were associated with the occurrence of MetS.Welldesigned cohort and caseecontrol studies are needed to provide evidence for the use of TCM to prevent and treat MetS.

Relationship between traditional Chinese medicine syndrome differentiation and imaging characterization to the radiosensitivity of nasopharyngeal carcinoma

Background and Objective: Traditional Chinese medicine (TCM) is a well established and time-honored practice in China, employing syndrome differentiation as a basis for the treatment of disease. According to different TCM syndrome typing findings, combining modern medical methods with TCM approaches can improve the quality of life and comprehensive effect on patients with nasopharyngeal carcinoma (NPC). This study investigated the relationship between TCM syndrome typing and imaging characterization to radiosensitivity as to provide objective evidence for the integration of Chinese and modern medical approaches in the treatment of NPC. Methods: Prior to treatment, TCM syndrome typing, computed tomography (CT) and magnetic resonance imaging (MRI) were performed on 147 patients pathologically classified with NPC. The status of tumor remission was radiologically evaluated at accumulated doses of 20 Gy, 40 Gy and 60 Gy, and at 3 months after completion of radiotherapy. Statistical results were analyzed by the Friedman and K-W test procedures. Results: Prior to treatment, TCM syndrome typing of NPC included Lung Heat, Blood Stasis, Phlegm Congealment and Blood Stasis-Phlegm Congealment. Lung Heat typing accounted for the highest proportion at 34.7% (51/147), followed by Phlegm Congealment at 32.7% (48/147), Blood Stasis at 17.0% (25/147) and Blood Stasis-Phlegm Congealment at 15.7% (23/147). Radiological imaging demonstrated a higher incidence of cervical lymph node metastases in Phlegm Congealment and Blood Stasis-Phlegm Congealment types (P < 0.05), while Blood Stasis and Blood Stasis-Phlegm Congealment types were more prone to skull base invasion (P < 0.05). Residual tumor size was larger in Blood Stasis and Blood Stasis-Phlegm Congealment types than in Lung Heat and Phlegm Congealment types after 3 months of treatment (P < 0.05). Conclusions: Different radiological manifestations were observed in TCM syndrome typed NPC patients, with lesser radiosensitivity demonstrated in the Blood Stasis and the Blood Stasis-Phlegm Congealment types relative to the Lung Heat and Phlegm Congealment types.
