ABSTRACT

ObjectiveTo explore the elements, distribution and characteristics of traditional Chinese medicine (TCM) syndromes in depressive episodes of bipolar disorder (BD). MethodsBasic information, along with the four examination information, the Hamilton Depression Scale and Young Mania Rating Scale scores, were collected from 293 outpatients with BD at Beijing Anding Hospital, Capital Medical University. The four examination information with an occurrence rate greater than 12% were retained. The R language “dist” function was used to calculate the distances between samples using the Euclidean distance method. The hierarchical clustering of the four examination information was performed using the “hclust” function and the squared Euclidean distance method. A team of five researchers was formed to determine the nature and location of the essential elements of TCM syndrome in BD based on the clustering results. The PC algorithm was used to construct a Bayesian network model of the essential elements. The working group combined the essential elements of TCM syndromes in the Bayesian network according to the reference model results, and then extracted common TCM syndromes. The score of each patient based on the essential elements was matched with the common TCM syndromes to determine the syndrome type of each patient. The working group then performs conformity and revision based on this, obtaining the final distribution of TCM syndromes for the patients. ResultsThere were 77 common TCM symptoms in BD with a frequency greater than 12%. The top 15 symptoms with higher frequencies were slippery pulse, mental fatigue and lack of strength, wiry pulse, excessive rumination, preference for solitude, vexation, agitation and irritability, dry mouth, palpitations, profuse dreaming, unwarranted worries, chest oppression, thin white coating, amnesia, frequent sighing, and poor appetite. TCM syndrome elements of BD can be grouped into 11 categories. The nature of disease-related essential elements included fire, qi deficiency, blood deficiency, qi counterflow, yin deficiency, dampness, heat, fire from constraint, and phlegm. The location of disease-related essential elements included heart, liver, spleen, stomach, kidney, bladder channel, and gallbladder. By constructing a Bayesian network model and considering the opinions from the experts, six common syndromes of BD were identified, among which the highest proportion was heart-stomach heat accumulation, accounting for 27.99% (82 cases), followed by heart-spleen deficiency (55 cases, 18.77%), non-interaction between the heart and the kidney (49 cases, 16.72%), liver constraint and blood deficiency (42 cases, 14.33%), heart qi deficiency (37 cases, 12.63%), and damp-heat in the liver and gallbladder (28 cases, 9.56%). ConclusionsThe nature of disease-related elements of BD are predominantly fire and heat, while the location of disease-related essential elements are primarily associated with the heart, liver, and spleen. The most common TCM syndromes are heart-stomach heat accumulation and heart-spleen deficiency.

ABSTRACT

ObjectiveTo compare the therapeutic effects of oral Chinese medicines (including Chinese patent medicines) on coronary artery disease (CAD) by the Bayesian network Meta-analysis. MethodThe randomized controlled trials of treating CAD with oral Chinese medicines were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, PubMed, Web of Science, Embase, and Cochrane Library from the inception to December 1, 2022. The Cochrane risk of bias assessment tool was used to evaluate the quality of the included articles. The direct meta-analysis was performed to compare the performance of oral Chinese medicines alone and in combination with Western medicine in the treatment of CAD in terms of intima-media thickness (IMT), vascular endothelial function, plaque score, hypersensitive C-reactive protein (hs-CRP), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and total response rate. Furthermore, the Bayesian network Meta-analysis was performed to compare the therapeutic effects of different Chinese medicines. ResultA total of 41 articles were included. The direct meta-analysis results showed that Chinese medicines combined with Western medicine outperformed Western medicine alone in recovering all the indicators of CAD. The Bayesian network meta-analysis yielded the following results. In terms of the total response rate, modified Huangqi Guizhi Wuwutang and Sanqi Huayu pills had obvious advantages over other Chinese medicines. In terms of IMT and plaque score, Xiaoban Huazhuo decoction, Yiqi Tongluo formula, Ruangan Jiangzhi capsules, and Guanxin Shutong capsules had obvious advantages over other Chinese medicines. In terms of blood lipid indicators, Shenqi Roumai mixture, Ruangan Jiangzhi capsules, Xiaoban Huazhuo decoction, Qiwei Sanxiong decoction, and Sanqi Huayu pills were superior to other Chinese medicines. The Chinese medicines above mainly had the functions of activating blood, resolving stasis, resolving phlegm, and dredging vessels. ConclusionThe combination of oral Chinese medicines and Western medicine is effective in treating CAD. Clinicians can use the drugs targeting abnormal indicators according to the results of this Bayesian network meta-analysis combined with the actual situation of patients to achieve better therapeutic effects.

ABSTRACT

In the digital transformation of Chinese pharmaceutical industry, how to efficiently govern and analyze industrial data and excavate the valuable information contained therein to guide the production of drug products has always been a research hotspot and application difficulty. Generally, the Chinese pharmaceutical technique is relatively extensive, and the consistency of drug quality needs to be improved. To address this problem, we proposed an optimization method combining advanced calculation tools(e.g., Bayesian network, convolutional neural network, and Pareto multi-objective optimization algorithm) with lean six sigma tools(e.g., Shewhart control chart and process performance index) to dig deeply into historical industrial data and guide the continuous improvement of pharmaceutical processes. Further, we employed this strategy to optimize the manufacturing process of sporoderm-removal Ganoderma lucidum spore powder. After optimization, we preliminarily obtained the possible interval combination of critical parameters to ensure the P_(pk) values of the critical quality properties including moisture, fineness, crude polysaccharide, and total triterpenes of the sporoderm-removal G. lucidum spore powder to be no less than 1.33. The results indicate that the proposed strategy has an industrial application value.

ABSTRACT

Background Falls are one of the most important types of occupational injuries. The incidence of falls is high in manufacturing workers. However, most of the studies on falls in China focus on primary and secondary school students and the elderly, and there are few studies on falls in the occupational population. Objective To evaluate efficiency of Bayesian network model in predicting fall injury risks in manufacturing enterprise staff, and impacts from work content, work environment, enterprise status, and health management on falls and their mutual relationships, and provide a scientific basis for enterprises to carry out fall-associated injury intervention. Methods Data from the European Survey of Enterprises on New and Emerging Risks (ESENER) were used. The survey provided data on work content, working environment, enterprise status, and health management of enterprises in European countries. The outcome indicator, was fall injury risks reported in enterprises. A total of 23 potential impact factors covering work content, working environment, enterprise status, and health management were screened by least absolute shrinkage and selection operator (LASSO) regression, followed by Bayesian network model for structure learning and parameter learning and area under the curve (AUC) for model fitness evaluation, using R and Netica 5.18. Diagnostic inference analysis was also conducted to identify key influencing factors and key influencing chains of fall injury risks based on the change rate of fall injury risks. Results In 5997 enterprises surveyed, 2573 (42.9%) enterprises reported fall injury risks. Ordered by their coefficient estimates from high to low, the 14 variables (mean-squared error=0.20) selected by LASSO regression were: manual handling, repetitive arm movement, poor posture, using desktop computers, and using robots in the category of work content; abnormal temperature and noise in the category of working environment; company size and employee quality in the category of enterprise status; mental health training, regular risk assessment, availability of psychologists, health and safety procedures, and provision of psychological counseling in the category of health management. The fitting result of Bayesian network model for fall injury risks was good (AUC=0.779). The Bayesian network diagnostic inference identified five key influencing factors, including abnormal temperature (change rate=35.9%), poor posture (change rate=27.3%), noise (change rate=23.4%), manual handling (change rate=18.2%), and repetitive arm movement (change rate=5.1%). The key influencing chain was "manual handling - poor posture - repetitive arm movement - fall injury risks" (combined change rate=16.9%). Conclusion The Bayesian network model has a good predictive performance in predicting the risk of falls in manufacturing enterprises. Manufacturing enterprises need to focus on jobs involving manual handling and repetitive arm movement, identify and improve workers' poor posture and mental health problems, and avoid workers working in harsh temperature or noise environment.

ABSTRACT

Abstract Improving the accuracy of protein secondary structure prediction has been an important task in bioinformatics since it is not only the starting point in obtaining tertiary structure in hierarchical modeling but also enhances sequence analysis and sequence-structure threading to help determine structure and function. Herein we present a model based on DSPRED classifier, a hybrid method composed of dynamic Bayesian networks and a support vector machine to predict 3-state secondary structure information of proteins. We used the SCOPe (Structural Classification of Proteins-extended) database to train and test the model. The results show that DSPRED reached a Q3 accuracy rate of 82.36% when trained and tested using proteins from all SCOPe classes. We compared our method with the popular PSIPRED on the SCOPe test datasets and found that our method outperformed PSIPRED.

ABSTRACT

To systematically evaluate the efficacy and safety of traditional Chinese medicine injections combined with antiviral wes-tern medicine in the treatment of influenza by Bayesian network Meta-analysis. Four Chinese databases(CNKI, Wanfang, VIP, CBM) and three English databases(PubMed, EMbase, Cochrane Library) were retrieved by computer for randomized controlled trials(RCT) about the comparison between the combined administration of traditional Chinese medicine injections with antiviral western medicine(or with placebo) and the single administration of antiviral western medicine in the treatment of influenza, or the comparison between two different traditional Chinese medicine injections combined with antiviral western medicine in the treatment of influenza. The retrieval time was from the establishment of the databases to July 2020. Two researchers independently screen out the literatures and extracted the data according to the inclusion criteria and exclusion criteria. The included studies were evaluated by the Cochrane 5.1 bias risk assessment tool, and data analysis was conducted by ADDIS 1.16.8 and Stata 14.0. A total of 49 literatures about 5 061 cases were included finally, involving six traditional Chinese medicine injections, namely Reduning Injection, Xiyanping Injection, Tanreqing Injection, Yanhuning Injection, Qingkailing Injection and Shuanghuanglian Injection. The results of network Meta-analysis,(1)in terms of total effective rate, 6 traditional Chinese medicine injections combined with antiviral western medicine was better than antiviral western medicine alone. In terms of probability sorting, Shuanghuanglian Injection combined with antiviral western medicine ranked first.(2)There was no significant statistical difference in adverse reaction rate among all groups, but Reduning Injection ranked first in the probability sorting, due to the least side effects.(3)In terms of antipyretic time, Yanhuning Injection, Xiyanping Injection and Tanreqing Injection combined with antiviral western medicine was better than antiviral western medicine alone and Xiyanping Injection ranked first in the probability sorting.(4)In terms of cough relief time, Qingkailing Injection and Tanreqing Injection combined with antiviral western medicine was better than antiviral western medicine alone and Qingkailing Injection was superior to Yanhuning Injection. Qingkailing Injection combined with antiviral western medicine ranked first in the probability sorting.(5)In terms of the length of hospital stay, Xiyanping Injection, Tanreqing Injection and Reduning Injection combined with antiviral western medicine was superior to antiviral western medicine alone, and Reduning Injection ranked first in the probability sorting due to the shortest hospital stay. Because of the small quantity and low quality of included studies, the results of this study shall be regarded cautiously and comprehensively. In the future, multi-center, large-sample and clinical randomized controlled trials shall be conducted to verify the results.

ABSTRACT

In this study, Honghua Injection, Danshen Injection, Shenkang Injection, Shuxuetong Injection, Lulutong Injection, Shenxiong Glucose Injection and Chuanxiong Injection were compared for their clinical efficacy on chronic renal insufficiency by using the method of network Meta-analysis, with Western medicine as the common reference. The randomized controlled trial(RCT) of Hong-hua Injection, Danshen Injection, Shenkang Injection, Shuxuetong Injection, Lulutong Injection, Shenxiong Glucose Injection and Chuanxiong Injection for the treatment of chronic renal insufficiency were obtained by computer-based retrieval. The literature quality was evaluated by using the method in Cochrane Reviewer's Handbook 5.1 after independent screening of the included literature by two reviewers. The RJAGS package and GEMTC package of RevMan 5.3, GEMTC software, R software were used for statistical analysis to compare and sort the different injections in terms of efficacy. A total of 6 197 patients with chronic renal failure were included in 79 RCTs, involving 8 treatment measures. The effective rates of conventional treatment combined with Shenxiong Injection(OR=3.55, 95%CI[1.98, 6.37], P<0.000 1), Honghua Injection(OR=3.77, 95%CI[2.45, 5.81], P<0.000 01), Shuxuetong Injection(OR=6.71, 95%CI[3.30, 13.65], P<0.000 01) and Shenkang Injection(OR=4.14, 95%CI[3.42, 5.03], P<0.000 01) were all better than that in control group, and the effective rate of Honghua Injection combined with conventional treatment(OR=3.89, 95%CI[1.73, 8.74], P=0.001) was better than that in Danshen Injection combined with conventional treatment, all with statistically significant differences. By comprehensive comparison, Shuxuetong Injection, Honghua Injection and Shenkang Injection combined with Western medicine had good clinical effect on the effective rate, serum creatinine reduction and urea nitrogen reduction in patients with chronic renal insufficiency. However, due to the relatively low quality of the included literature, the conclusion has yet to be verified clinically.

ABSTRACT

OBJECTIVE: To analyze the effect of gene-gene and gene-occupational stress interaction on hypertension in oil workers by Bayesian network(BN) analysis. METHODS: A total of 1 233 oil workers from Xinjiang Karamay Oilfield Company were selected as research subjects by the typical sampling method. The blood pressure was measured. The polymerase chain reaction-restriction fragment length polymorphism was used to evaluate the single nucleotide polymorphism(SNP) in α-adductin(ADD1) and β_2-adrenal receptor(β_2-AR) genes. The Effort-Reward Imbalance(ERI) Questionnaire was used to evaluate the ERI model occupational stress of oil workers. BN was used to analyze gene-gene and gene-occupational stress interactions. RESULTS: The detection rate of hypertension and ERI model occupational stress of these oil workers were 25.5%(315/1 233) and 47.4%(585/1 233) respectively. The AA, AG, and GG genotype and the frequency distribution of allele A and G at ADD1 rs17833172 were statistically different in these two groups(all P<0.05). There was no statistical significance in genotypes of GG, GT and TT at Gly460Trp rs4961(P>0.05); but the difference of the frequency of G and T alleles was statistically significant(P<0.05). There was no statistical significance in genotype distribution of AA, AG and GG, and frequency distribution of A and G in β_2-AR-1023 G/A rs2053044 and+252 G/A rs1042717(all P>0.05). After controlling the confounding factors including gender, education level, marital status, smoking, alcohol drinking and body mass index, the occupational stress group had a higher risk of hypertension than the no-occupational stress group(P<0.05, the odds ratio was 1.33, the 95% confidence interval was 1.01-1.74). The directed acyclic graph constructed by BN showed that the rs17833172 and Gly460Trp rs4961 sites of the ADD1 gene was directly associated with hypertension, and the β_2-AR+252 G/A rs1042717 site was indirectly associated with hypertension because of the ADD1 rs17833172 and Gly460Trp rs4961 sites. The interaction between occupational stress and ADD1 and β_2-AR was not associated with hypertension. CONCLUSION: The incidence of hypertension in oil field workers is correlated to occupational stress, and ADD1 gene rs17833172 and Gly460Trp rs4961 polymorphism. The gene-gene interaction between β_2-AR+252 G/A rs1042717 locus and ADD1 Gly460Trp rs4961 and rs17833172 locus is associated with hypertension, while the interaction between the four loci of ADD1 and β_2-AR and occupational stress has no effect on hypertension in the oil workers.

ABSTRACT

This paper aims to construct a Bayesian(BN) fault diagnosis model of traditional Chinese medicine dry granulation based on the failure model and effect analysis(FMEA), effectively control risk factors and ensure the quality of granules.Firstly, the risk ana-lysis of dry granulation process was carried out with FMEA, and the selected medium and high risk factors were taken as node variables to establish corresponding BN network with causality.According to the mathematical reasoning method of probability theory, the model was accurately inferred and verified by Netica, and the granule nonconformance was used as the evidence for reversed reasoning to determine the most likely cause of the failure that affected the granule quality.The BN fault diagnosis model of traditional Chinese medicine dry gra-nulation was established based on the medium and high risk factors of process, prescription and equipment screened out by FMEA, such as roller pressure, raw material viscosity, clearance between rollers in the paper.The fault diagnosis of traditional Chinese medicine dry granulation process was then carried out according to the model, and the posterior probability of each node under the premise of nonconforming granule quality was obtained.This method could provide strong support for operators to quickly eliminate faults and make decisions, so as to improve the efficiency and accuracy for fault diagnosis and prediction, with innovation in its application.

ABSTRACT

Objective:To carry out the risk assessment on the factors in the process of granulation fluidized bed of traditional Chinese medicine(TCM) by using failure model and effect analysis(FMEA) and Bayesian network(BN), in order to effectively control risk factors and improve product quality. Method:The risk analysis of the fluidized bed granulation process was carried out by FMEA and the selected medium risk and high risk factors were taken as the main control points, the corresponding BN was established. The sensitivity analysis was used to screen out the main risk factors affecting particle fluidity, particle size uniformity, solubility and product cleanliness, the occurrence probability of each risk factor was determined by the evidence of unqualified particle quality, finally, taking fluidized bed granulation process of Sanye tablets as an example, the FMEA and BN were combined into the risk assessment process to verify the effectiveness and reliability of the method. Result:Based on the middle and high risk points of fluidized bed process, particle size of raw materials, moisture content and hygroscopicity of raw materials, dosage, concentration and addition amount of binder, cleaning degree and integrity of collection bag, and nozzle position, which were selected by FMEA, a fluidized bed granulation risk network with causality was constructed. Among them, hygroscopicity of raw materials, concentration and addition amount of binder, inlet temperature and atomization pressure were high probability risk factors, and the probability of occurrence were 55%, 63%, 59%and 58%, respectively. According to the Bayesian risk relationship network which controlled Sanye tablets fluidized bed granulation analysis results showed that the P values of inlet temperature, atomization pressure and concentration of binder were 0.003 4, 0.032 6 and 0.041 8, respectively in the regression model of influencing factors and particle size uniformity, indicating that there was a significant correlation between the three factors and the particle quality, which was basically consistent with the conclusion obtained by FMEA-BN method. Conclusion:The combination of FMEA and BN for visualized risk assessment of fluidized bed granulation helps to effectively control the risk factors in the granulation process, reduce product quality risks and provide strong support for the improvement of granulation process of TCM.

ABSTRACT

@#Dengue is an increasing threat in Malaysia, particularly in the more densely populated regions of the country. We present an Artificial Intelligence driven model in predicting Aedes outbreak, using predictors of weather variables and vector indices sourced from the Ministry of Health. Analysis and predictions to estimate Aedes populations were conducted, with its results being used to infer the possibility of dengue outbreaks at pre-determined localities around the Klang Valley, Malaysia. A Bayesian Network machine learning technique was employed, with the model being trained using predictor variables such as temperature, rainfall, date of onset and notification, and vector indices such as the Ae. albopictus count, Ae. aegypti count and larval count. The interfaces of the system were developed using the C# language for Server-side configuration and programming, and HTML, CSS and JavaScript for the Client Side programming. The model was then used to predict the population of Aedes at periods of 7, 14, and 30 days. Using the Bayesian Network technique utilising the above predictor variables we proposed a finalised model with predictive accuracy ranging from 79%-84%. This model was developed into a Graphical User Interface, which was purposed to assist and educate the general public of regions at risk of developing dengue outbreak. This remains a valuable case-study on the importance of public data in the context of combating a public health risk via the development of models for predicting outbreaks of dengue which will hopefully spur further sharing of data by all parties in combating public health threats.

ABSTRACT

Objective@#To investigate the clinical value of Bayesian network in predicting survival of patients with advanced gallbladder cancer(GBC)who underwent curative intent surgery.@*Methods@#The clinical data of patients with advanced GBC who underwent curative intent surgery in 9 institutions from January 2010 to December 2015 were analyzed retrospectively.A median survival time model based on a tree augmented naïve Bayes algorithm was established by Bayesia Lab software.The survival time, number of metastatic lymph nodes(NMLN), T stage, pathological grade, margin, jaundice, liver invasion, age, sex and tumor morphology were included in this model.Confusion matrix, the receiver operating characteristic curve and area under the curve were used to evaluate the accuracy of the model.A priori statistical analysis of these 10 variables and a posterior analysis(survival time as the target variable, the remaining factors as the attribute variables)was performed.The importance rankings of each variable was calculated with the polymorphic Birnbaum importance calculation based on the posterior analysis results.The survival probability forecast table was constructed based on the top 4 prognosis factors. The survival curve was drawn by the Kaplan-Meier method, and differences in survival curves were compared using the Log-rank test.@*Results@#A total of 316 patients were enrolled, including 109 males and 207 females.The ratio of male to female was 1.0∶1.9, the age was (62.0±10.8)years.There was 298 cases(94.3%) R0 resection and 18 cases(5.7%) R1 resection.T staging: 287 cases(90.8%) T3 and 29 cases(9.2%) T4.The median survival time(MST) was 23.77 months, and the 1, 3, 5-year survival rates were 67.4%, 40.8%, 32.0%, respectively.For the Bayesian model, the number of correctly predicted cases was 121(≤23.77 months) and 115(>23.77 months) respectively, leading to a 74.86% accuracy of this model.The prior probability of survival time was 0.503 2(≤23.77 months) and 0.496 8(>23.77 months), the importance ranking showed that NMLN(0.366 6), margin(0.350 1), T stage(0.319 2) and pathological grade(0.258 9) were the top 4 prognosis factors influencing the postoperative MST.These four factors were taken as observation variables to get the probability of patients in different survival periods.Basing on these results, a survival prediction score system including NMLN, margin, T stage and pathological grade was designed, the median survival time(month) of 4-9 points were 66.8, 42.4, 26.0, 9.0, 7.5 and 2.3, respectively, there was a statistically significant difference in the different points(P<0.01).@*Conclusions@#The survival prediction model of GBC based on Bayesian network has high accuracy.NMLN, margin, T staging and pathological grade are the top 4 risk factors affecting the survival of patients with advanced GBC who underwent curative resection.The survival prediction score system based on these four factors could be used to predict the survival and to guide the decision making of patients with advanced GBC.

ABSTRACT

OBJECTIVE:To evaluate the clinical efficacy of somatostatin and protease inhibitors in the prevention of post-ERCP pancreatitis(PEP)and hyperamylasemia(PEHA). METHODS:Retrieved from databases as Cochrane Library, PubMed,Embase,RCTs about therapeutic efficacy of somatostatin and protease inhibitors in the prevention of PEP were included. EndNote X8 software was used to eliminate duplicate documents,and the quality of included studies was evaluated according to Cochrane System Evaluator Manual version 5.3.3. Bayesian network Meta-analysis was conducted by MCMC method with R 3.4.3 software Gemtc 0.8 program package. Risk of bias was evaluated by using Rev Man 5.3 software,and risk of publication was evaluated by using Stata 14.0 software draws funnel map. RESULTS:A total of 33 RCTs were included,involving 10 576 patients,somatostatin,gabexate,ulinastatin,nafamostat. Network Meta-analysis showed that in the prevention of PEP,the order of curative effect was as follows:somatostatin(intravenous bolus)>nafamostat>ulinastatin>somatostatin(high-dose intravenous drip)>gabexate,somatostatin(low-dose intravenous drip)was ineffective. In the prevention of PEHA,the order of probability being somatostatin(high-dose intravenous drip)>somatostatin(intravenous bolus)>ulinastatin. Only nafamostat was effective in preventing PEP in high-risk patients. CONCLUSIONS:Compared with somatostatin(low-dose intravenous drip)and gabexate,somatostatin(intravenous bolus)and somatostatin(high-dose intravenous drip),ulinastatin,nafamostat can more effectively prevent PEP. Nafamostat cannot prevent PEHA,but can prevent PEP in high risk patients.

ABSTRACT

Under the available data gathered from a coronary study questionnaires with 10 792 cases,this article constructs a Bayesian network model based on the tabu search algorithm and calculates the conditional probability of each node,using the Maximum-likelihood.Pros and cons of the Bayesian network model are evaluated to compare against the logistic regression model in the analysis of coronary factors.Applicability of this network model in clinical study is also investigated.Results show that Bayesian network model can reveal the complex correlations among influencing factors on the coronary and the relationship with coronary heart diseases.Bayesian network model seems promising and more practical than the logistic regression model in analyzing the influencing factors of coronary heart disease.
