Objective To clarify the distribution of traditional Chinese medicine(TCM)pattern and its associated risk factors after percutaneous coronary intervention(PCI),and evaluate the re-porting quality of existing studies to guide future research standardization. Methods English databases including PubMed,Cochrane Library,and Web of Science,as well as Chinese databases including China National Knowledge Infrastructure(CNKI),China Scientific Journal Database(VIP),and Wanfang Database were searched to retrieve papers about PCI.The time span for the paper retrieval was set from the foundation of the databases to October 1,2023.Statistical analyses were performed using Stata 12 and Python(V 3.9).The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)statement was used to assess the reporting quality of included studies. Results Overall,1 356 articles were selected,and 40 cross-sectional studies were included with 10 270 participants.The most common TCM patterns before,one to two weeks after,and six months to one year after PCI was Qi stagnation and blood stasis(n=261,36.45%),inter-twined phlegm and blood stasis(n=109,27.18%),and Qi deficiency and blood stasis(n=645,37.03%),respectively.Smoking[odds ratio(OR)=1.15,95%confidence interval(CI)(0.83-1.47),I2=24.7%,P=0.257],pattern of congealing cold and Qi stagnation[OR=4.62,95%CI(1.37-7.86),I2=61.6%,P=0.074],and low-density lipoprotein(LDL)[OR=1.38,95%CI(0.92-1.85),I2=12.2%,P=0.286]were risk factors for restenosis.Hypertension[OR=7.26,95%CI(3.54-14.88),I2=91.6%,P=0.001],and overweight[i.e.,body mass index(BMI)>23][OR=1.20,95%CI(1.07-1.35),I2=85.3%,P=0.009]were significant risk factors of concomi-tant anxiety. Conclusion This systematic review and meta-analysis revealed that patients with different TCM pattern types have distinct characteristics and risk factors after PCI.More high-quality studies are warranted to provide supportive evidence for future research and clinical practice.

Objective:To analyze TCM tongue diagnosis related research on coronary heart disease (CHD) at home and abroad using the method of bibliometrics; To provide reference for further research on clinical diagnosis and treatment of CHD.Methods:Research literature about TCM tongue diagnosis for CHD was retrieved from CNKI, VIP, CBM, Wanfang Data, PubMed, Embase, Cochrane Library and Web of Science from the establishment of the databases to December 31st, 2022. The key features of literature related to tongue diagnosis from CHD, including publication volume, region, institution, authors, and research hotspots, were analyzed using BICOMBS2.0, CiteSpace 6.1.R6, and Excel 2019 software.Results:Totally 364 Chinese articles and 5 English articles were included. Liaoning University of Traditional Chinese Medicine was the institution that published the most relevant research in Chinese, and Shanghai University of Traditional Chinese Medicine was the institution that published the most relevant research in English. Professor Wang Yiqin of Shanghai University of Traditional Chinese Medicine was the author with the largest number of publications in both Chinese and English, and the authors with the largest number of publications on Chinese research worked closely cooperate with each other. Chinese research focused on syndrome characteristics of CHD, objectification of tongue diagnosis and data mining based on the clinical experience of renowned TCM practitioners; the English research topic included modern data collection and analysis and expert consensus.Conclusions:The research team of tongue diagnosis for CHD in China has begun to take shape. There are few English articles on tongue diagnosis for CHD, and the development level is relatively lagging behind. In the future, different institutions and researchers need to strengthen international cooperation to enhance the international influence of TCM diagnostics.

Objective To study Chinese medicine consultation strategies to achieve rapid capture of key information about patients'conditions and to advance the development of objectification in Chinese medicine consultation.Methods A symptom questioning model based on frequent pattern mining algorithm in correlation analysis was used,and a cross-merging method was used to establish a TCM symptom questioning strategy between single-system symptom questioning and multi-system integrated symptom questioning in TCM,to achieve the shortest time and highest efficiency in capturing key information about the patient's condition.Results A breakthrough from single-system questioning to five-system integrated questioning was achieved,and the process of efficiently obtaining information about the patient's condition was achieved through both single-system and five-system symptom questioning modes,and the system was able to obtain 92%of the patient's symptom information with at most 65%fewer questions than the traditional scale questioning method,greatly improving the efficiency of obtaining information about the patient's symptoms.Conclusion With the two different symptom questioning modes,the traditional TCM questioning mode of asking patients based on scales is broken,the time to obtain symptoms from patients is shortened,the questioning process is simplified,and discrepancies due to inexperience or human subjectivity are reduced,which can be used in clinical aids to diagnosis in TCM.

Objective To explore the characteristics of TCM syndromes in patients with coronary heart disease complicated with hypertension and diabetes based on latent structure model.Methods A multi-center cross-sectional study was used to collect the four diagnostic information of patients with coronary heart disease by using the Four Diagnostic Collection Scales of TCM developed by our research group,and a clinical database was established.Combined with frequency analysis and expert opinions,the four diagnostic information was screened to construct a latent structure model.Results Totally 702 patients with coronary heart disease complicated with hypertension and diabetes were collected.A total of 40 high-frequency four-diagnosis symptoms were screened,and 18 latent variables were obtained by latent structure model analysis.The model BIC score was-17 604.38.The latent variables in the model were comprehensively clustered,and it was found that the syndrome elements of disease location in patients with coronary heart disease complicated with hypertension and diabetes were mainly heart,liver,kidney,etc.,and the syndrome elements of disease nature were mainly qi deficiency,yin deficiency,qi stagnation,phlegm turbidity,blood stasis,etc.The syndrome types were mainly phlegm and blood stasis syndrome,spleen and kidney yang deficiency syndrome,liver depression and qi stagnation syndrome,liver and kidney yin deficiency syndrome,damp-heat intrinsic syndrome,and the mutual information and information coverage between each syndrome type and the four diagnostic information were suggested.Conclusion Latent structure model analysis can provide a qualitative and quantitative basis for the syndrome classification of patients with coronary heart disease complicated with hypertension and diabetes.

Background: and Purpose The eye-movement examination can be applied as a noninvasive method to identify multiple-system atrophy (MSA). Few studies have investigated eye movements during the early stage of MSA with predominant parkinsonism (MSA-P). We aimed to determine the characteristic oculomotor changes in the early stage of MSA-P. Methods: We retrospectively selected 17 patients with MSA-P and 40 with Parkinson’s disease (PD) with disease durations of less than 2 years, and 40 age-matched healthy controls (HCs).Oculomotor performance in the horizontal direction was measured in detail using videonystagmography. Results: We found that the proportions of patients with MSA-P and PD exhibiting abnormal eye movements were 82.4% and 77.5%, respectively, which were significantly higher than that in the HCs (47.5%, p<0.05). Compared with HCs, patients with MSA-P presented significantly higher abnormal proportions of fixation and gaze-holding (17.6% vs. 0%), without-fixation (47.1% vs. 0%), prolonged latency in reflexive saccades (29.4% vs. 5.0%), memory-guided saccades (93.3% vs. 10.0%), and catch-up saccades in smooth-pursuit movement (SPM, 41.2% vs. 0) (all p<0.05). Compared with those with PD, patients with MSA-P presented a significantly higher proportion of catch-up saccades in SPM (41.2% vs. 2.5%, p<0.001). Conclusions MSA-P presented the characteristic of catch-up saccades in SPM in the early stage, which may provide some value in differentiating MSA-P from PD.

Objective To collect information from the traditional Chinese medicine(TCM)four diagnostic information of patients with coronary heart disease(CHD)and to observe the characteristics of their Chinese medicine syndrome factor at different ages,to provide an objective basis for the Chinese medicine treatment of patients with CHD at different ages.Methods The TCM Four Diagnostic Information Collection Scale for CHD developed by the group was used to collect the four diagnostic information of patients with coronary heart disease,and the syndrome elements were extracted according to the syndrome differentiation standard to observe the distribution of syndrome elements at different ages.Results CHD is located in the heart and accompanied by liver,kidney,stomach,lung and other organs.Qi deficiency is the most common syndrome factor,followed by phlegm turbidity,yin deficiency,blood stasis and qi stagnation.Among the syndrome elements of disease location,the heart and liver were the most common in the young group,and the heart and kidney were more common in the middle-aged group and the elderly group.Among the syndrome elements of disease nature,qi deficiency was more common in the young group,phlegm turbidity and qi stagnation were more common in the empirical group,and qi deficiency and phlegm turbidity were the most frequent.In the middle-aged group,qi deficiency was more common in deficiency syndrome,phlegm turbidity and blood stasis were more common in excess syndrome,and the frequency of qi deficiency and phlegm turbidity and blood stasis was the highest.In the elderly group,qi deficiency and yin deficiency were more common in deficiency syndrome,phlegm turbidity and blood stasis were more common in excess syndrome,and qi and yin deficiency combined with phlegm turbidity and blood stasis had the highest frequency.Conclusion The combination of syndrome elements in patients with CHD in different age groups has its own characteristics.The young,middle and elderly groups are all visible in the mixture of deficiency and excess,while the young group is the most common with qi deficiency and phlegm turbidity,the middle-aged group is the most common with qi deficiency and phlegm turbidity and blood stasis,and the elderly group is the most common with qi and yin deficiency and phlegm turbidity and blood stasis.With the increase of age,the complexity of the combination of syndrome elements is higher.

BackgroundSleep disorder can adversely affect human physical and mental health， with important implications for socioeconomic development. And higher vocational college students are subject to various pressures and stimuli exerted by academic studies， job seeking and family socioeconomic status， which may contribute to the onset insomnia symptom or sleep disorder. ObjectiveTo discuss the sleep status and influencing factors among higher vocational college students， and to provide references for improving their sleep status. MethodsIn January and February， 2022， a stratified random sampling method was utilized to enroll 3 300 students from five higher vocational colleges in Wenjiang district of Chengdu city. All the participants were assessed using Insomnia Severity Index （ISI）， Patient Health Questionnaire Depression Scale-9 item （PHQ-9） and Generalized Anxiety Disorder Scale-7 （GAD-7）. Pearson correlation analysis was conducted to test the correlation of ISI with PHQ-9 and GAD-7 scores， and the Logistic regression analysis was performed to identify the influencing factors of insomnia symptom in higher vocational college students. ResultInsomnia symptom was detected in 81.90% （2 497 / 3 300） of higher vocational college students. The detection rate of insomnia symptom among vocational college students yielded statistical difference in terms of gender， family socioeconomic status， being an only child or having siblings， degree of psychological pressure exerted by academic studies or job seeking， amount of hours spent on Internet per day， frequency of physical exercise， and the presence or absence of anxiety symptom and depression symptom （χ²=21.032， 22.172， 8.983， 75.939， 36.781， 32.350， 54.512， 86.561， P<0.01 or 0.05）. Among higher vocational college students， ISI score was positively correlated with GAD-7 and PHQ-9 scores （r=0.620， 0.714， P<0.01）， and GAD-7 score was positively correlated with PHQ-9 score （r=0.824， P<0.01）. Gender， family socioeconomic status， degree of psychological pressure exerted by academic studies or job seeking， amount of hours spent on Internet per day， frequency of physical exercise， and the presence or absence of anxiety symptom and depression symptom were effective factors in predicting the insomnia symptom in higher vocational college students （P<0.01 or 0.05）. ConclusionFemale gender， average and below average family socioeconomic status， moderate-to-severe degree of psychological pressure exerted by academic studies or job seeking， spending 2~5 h， 5~7 h or >7 h on Internet per day， inadequate physical exercise and presence of depressive symptom are the risk factors for insomnia symptom in higher vocational college students.［Funded by Sichuan Provincial Primary Health Development Research Center in 2022， North Sichuan Medical College （number， SWFZ22-C-89）］

Objective:To explore the effect of knockdown of the homeobox gene paired-box 6 ( Pax6) on the biological behavior and epithelial-mesenchymal transition (EMT) of human lens epithelial cells (LECs). Methods:The SRA01/04 human LECs were divided into small interfering RNA-Pax6 (siRNA-Pax6) group transfected with siRNA-Pax6 and siRNA negative control (siRNA-NC) group transfected with disordered siRNA.Cell survival rate was detected by cell counting kit-8 method at 24, 48 and 72 hours after transfection.Cell cycle distribution and apoptosis were analyzed by flow cytometry at 48 hours after transfection.Migratory capability of cells was examined by cell scratch test at 24 hours after transfection.The mRNA relative expression levels of Pax6, α-crystallin A (CRYAA), α-crystallin B (CRYAB), Sox2, α-smooth muscle actin (α-SMA) and E-cadherin were detected by quantitative real-time PCR at 48 hours after transfection.The relative expression of Pax6 protein was detected by Western blot at 48 hours after transfection.Results:There was a significant difference in cell survival rates at different time points between the two groups ( Fgroup=4.776, P<0.05; Ftime=13.535, P<0.05). The cell survival rate of siRNA-Pax6 group was obviously lower than that of siRNA-NC group at 48 and 72 hours after transfection, and the differences were statistically significant (both at P<0.05). Compared with siRNA-NC group, the proportion of cells in G 0/G 1 phase was significantly increased and the proportion of cells in S phase was significantly reduced in siRNA-Pax6 group ( t=9.971, -5.063; both at P<0.05). The cell migration rate of siRNA-Pax6 group was (19.73±6.07)%, which was lower than (70.56±2.97)% of siRNA-NC group, showing a statistically significant difference ( t=-7.245, P<0.05). The relative expressions of Sox2 mRNA and α-SMA mRNA were lower, and the relative expression of E-cadherin mRNA was higher in siRNA-Pax6 group than siRNA-NC group, with statistically significant differences between them ( t=-23.254, -5.294, 6.062; all at P<0.01). The relative expression of CRYAA mRNA and CRYAB mRNA was significantly higher in siRNA-Pax6 group than siRNA-NC group, and the differences were statistically significant ( t=5.521, 8.270; both at P<0.01). The relative expressions of Pax6 mRNA and protein in siRNA-Pax6 group were 0.27±0.01 and 0.24±0.05, respectively, which were both lower than 1.00±0.05 and 1.14±0.10 in siRNA-NC group, showing statistically significant differences ( t=-14.456, -4.458; both at P<0.001). Conclusions:Silence of Pax6 can suppress the proliferation and EMT of human LECs and enhance the expression of crystallin.

Objective:To study the prevalence and clinical characteristics of hepatitis D patients.Methods:A total of 832 144 HBsAg positive persons who were from infectious department of Southwest Hospital Affiliated to Army Military Medical University were screened from January 1, 2010 to December 31, 2020. A total of 13 585 subjects completed relevant Hepatitis Delta virus (HDV) biomarker tests, 157 HDV patients were evaluated. The mean age was 53 ± 13 years, with a range of 22-85 years. The majority of these subjects were male. The prevalence, clinical characteristics, the outcome of 28 days follow-up and the influencing factors of the outcome were analyzed.Results:In recent 10 years, the screening rate related to hepatitis D was only 1.6% (13 585/832 144), and the screening rate was the highest in 2011, up to 4.13% (962/23 289); The positive rate of screening was only 1.17% (157/13 346). In 2012, the positive rate of screening was the highest, up to 3.56% (58/1627). In Southwest Hospital, the source of disease was 66.24% (104/157) in Chongqing, 22.93% (36/157) in Sichuan, 8.28% (13/157) in Guizhou, 1.27% (2/157) in Yunnan, and 0.64% (1/157) in each of Jiangxi and Tibet. Of 157 patients, 29 (18.47%) had non-cirrhotic with chronic low bilirubin hepatitis, 23.57% (37/157) was non-cirrhotic with chronic high bilirubin hepatitis, 28.66% (45/157) had acute-on-chronic liver failure (ACLF), 27.39% (42/157) had compensated cirrhosis or decompensated cirrhosis, and 1.91% (3/157) had primary hepatocellular carcinoma. The incidence of disease progression was 48.89% (22/48) of chronic-on-acute liver failure>33.33%(1/3) of primary hepatocellular carcinoma>25.58%(11/43) of compensated or decompensated cirrhosis>18.92%(7/37) of non-cirrhotic with chronic high bilirubin hepatitis>6.90%(2/29) of non-cirrhotic with chronic low bilirubin hepatitis ( P<0.05). Among them, 7.64%(12/157) had hepatic encephalopathy, and the rate of disease progression was 83.33%(10/12) ( P<0.05); 3.82% (6/157) of them had combined with other hepatophilic viruses including hepatitis C virus (HCV), Epstein-barr virus, (EBV), Cytomegalovirus (CMV) infections. Logistic regression analysis showed that old age, complication with hepatic encephalopathy, hyperbilirubinemia and prolonged coagulation time were independent risk factors affecting the outcome of hepatitis D. Conclusions:In recent 10 years, the screening rate of hepatitis D is low and the positive rate is not high. It should be noted that HDV infection can accelerate the progress of hepatitis and increase the risk of adverse liver outcomes.
