ObjectiveExploring the formula rules of commonly used traditional Chinese medicines（TCMs） for epidemic treatment from the Qin and Han dynasties to the Qing dynasty through data mining， providing reference for the prevention and control of contemporary epidemics. MethodsThe articles on epidemic treatment in the electronic database of Chinese Medical Code V5.0 were systematically searched， and the contents such as source， dynasty， author， diagnosis， formula name， therapeutic method and efficacy， and composition of medicines from each article that met the inclusion criteria were extracted. Then， an Excel standardized database was established， and Python programs were used for data mining to summarize the frequency of commonly used medicines and perform hierarchical cluster analysis， Pearson correlation analysis， and association rule analysis. ResultsA total of 1 595 formulas were included， involving 558 TCMs. The efficacy of these medicines could be classified into two categories， namely， expeling pathogenic factors and reinforcing healthy Qi. According to the frequency deconstruction analysis， high-frequency medicines were mainly detoxification， Fu-organ dredging， aromatization and promoting blood circulation， followed by the medicines with the effect of treating the lungs， such as clearing the lungs and resolving phlegm， clearing heat and purging the lungs， relieving cough and asthma， and purging the lungs and relieving asthma. And the proportions of acrid-warm herbs and acrid-cold herbs varied in different periods. Hierarchical clustering and correlation analysis both suggested TCMs for expeling pathogenic factors and reinforcing healthy Qi often formed stable combinations with high association degrees. Association rule analysis showed that the core acrid-warm herb was mainly Ephedrae Herba， and the core acrid-cold herb was mainly Forsythiae Fructus， resulting in the core formulas of Maxing Shigantang and Yinqiaosan. ConclusionThroughout history， the prevention and control of epidemics have been based on the principle of "preserving healthy Qi and avoiding toxic Qi"， focusing on the treatment of the causes and characteristics of epidemics through detoxification， Fu-organ dredging， and aromatization， emphasizing the use of Rhei Radix et Rhizoma and other herbs to dredge Fu-organ， eliminate toxins and pathogens， and playing the role of actively intervene with symptomatic medication. And based on the external manifestations of the body's struggle between evil and righteousness， diagnose and treatment according to syndrome differentiation was performed.

Objective To investigate the difference of the disease progression in patients with chronic obstructive pulmonary disease (COPD) with different muscle mass levels and the influence of related factors on the disease progression. Methods A total of 308 newly diagnosed patients with COPD from February 2021 to February 2022 were selected for this study. All patients were below moderate COPD. The patients were divided into two groups according to their muscle mass levels: sarcopenia group (98 cases) and control group (210 cases). The diagnostic criteria for sarcopenia were based on sarcopenia diagnostic thresholds: RSMI <7.0kg/m² in men and <5.4kg/m² for women. All subjects were followed up for 4 months to observe the progress of the patient's condition. The correlation between the muscle mass level and pulmonary function level, as well as the results of 6-minute walking test and CAT score was evaluated, and the influence of muscle mass level on the patient's disease progress was analyzed. At the same time, the potential influence of related factors (body fat rate, vitamin D level, etc.) on the condition of patients with different muscle mass levels was discussed. SPSS 19.0 software was used to perform statistical analysis. Results Under the same treatment intervention, the baseline and follow-up lung function improvement levels of patients in the sarcopenia group were lower than those in the control group, and the difference was statistically significant (P<0.05). At the same time, the baseline and follow-up 6-minute walk test results of the patients in the sarcopenia group were also worse than those of the control group, and the difference was statistically significant (P<0.05). Further correlation analysis was carried out between the patient's muscle mass level and the post-treatment pulmonary function indicators and 6MWD test level. The results showed that the muscle mass level was positively correlated with several pulmonary function indicators (FEV1, FEV1% predict) and 6MWD (both P<0.05). Considering the possible influence of other factors on the control and progress of the patient's condition, the present study used follow-up CAT score results to distinguish the prognosis of the patient's condition improvement, and used improvement and non-improvement as dependent variables to analyze the influence of various potential influencing factors. The results of regression model analysis showed that lower baseline muscle mass, women, lower body fat percentage, and lower vitamin D level were the main risk factors. Conclusion Under the same treatment condition, COPD patients with different muscle mass levels improve more slowly when complicated with sarcopenia and have poor prognosis. Women, lower body fat percentage and lower vitamin D level are potential risk factors for poor prognosis.

OBJECTIVE To explore the effect mechanism of Eucommia ulmoides on improving postpartum depression in rats. METHODS Pregnant rats were randomly divided into normal group， postpartum depression group， and low-dose and high-dose groups of E. ulmoides （1.34， 2.68 g/kg， calculated by crude drug）， with 10 rats in each group. Except for the normal group， the rats in other groups suffered from fear stress to induce postpartum depression model during pregnancy； at the same time of modeling， the administration groups were given relevant medicine intragastrically， while the normal group and postpartum depression group were given physiological saline intragastrically for 21 days. Postpartum behaviors of rats during the experiment were assessed using the open field test， Morris water maze test and sucrose preference test. Additionally， the levels of corticosterone （CORT） in serum， corticotropin releasing factor （CRF） and urocortin （UCN） in hypothalamus， and adrenocorticotropic hormone （ACTH） in hypophysis were detected； meanwhile， the protein expressions of CRF receptor 1 （CRFR1）， CRFR2， and voltage-dependent anion channel 1 （VDAC1） in hippocampal tissue were measured； the proportions of apoptotic cells and JC-1 high potential cells in hippocampal tissue were determined， and the morphology of hippocampal tissue was observed. RESULTS Compared with postpartum depression group， the high-dose group of E. ulmoides showed improvements in appetite， mental state， and hair color in rats； their body weight had increased； the scores of vertical movement， horizontal movement and self-sorting significantly increased； from the 2ed to 4th day avoidance latency significantly shortened， and the times of crossing the platform and the time of crossing the platform Δ 基金项目国家自然科学基金青年基金项目（No.82204789） significantly increased/prolonged （P＜0.05）； the ratio of glucose and water consumption significantly increased at 20 days of pregnancy and 30 days postpartum （P＜0.05）； the levels of CRF， UCN， ACTH and CORT， phagocytic rate， protein expressions of CRFR2 and VDAC1， and the proportion of apoptosis cells in hippocampal tissue were decreased significantly （P＜0.05）； the proportion of JC-1 high potential cells significantly increased （P＜0.05）， and the phenomenon of edema around neuronal cells was significantly improved. CONCLUSIONS E. ulmoides can improve postpartum depression by inhibiting excessive activation of hypothalamic-pituitary-adrenal axis， decreasing the expression of CRFR2， thereby inhibiting the expression of VDAC1， and decreasing the apoptosis of neuronal cells.

Objective:To understand the current status of personal protection in occupational population at high risk for brucellosis in China and provide evidence for the evaluation of implementation of National Brucellosis Prevention and Control Plan (2016-2020).Methods:Four counties in Shanxi Province and Xinjiang Uygur Autonomous Region were selected to conduct a questionnaire survey in occupational population at high risk for brucellosis from December 2019 to July 2020 by using cross-sectional survey methods.Results:A total of 2 384 persons at high risk for brucellosis were surveyed, and the standardized utilization rate of personal protective equipment (PPE) was 20.13% (480/2 384). The utilization rate of glove, mask, rubber shoe, and work cloth were 38.26% (912/2 384), 31.80% (758/2 384), 32.01% (763/2 384) and 30.87% (736/2 384),respectively. There were significant differences in the utilization rate and standardized utilization rate of the four types of PPE among populations in different age, occupation, educational level and area groups (all P<0.001). The utilization rate and standardized utilization rate of PPE were lower in people over 60 years old, women, farmers, and those with lower educational level. The results of multivariate analysis showed that occupation and area were the influencing factors for the standardized utilization of PPE, the standardized utilization rates of PPE were higher in herdsmen and veterinarians. The standardized utilization rate of PPE in Yanggao County and Huocheng County was significantly higher than that in Zuoyun County and Hunyuan County. Conclusions:The utilization rate of the four types of PPE in occupational population at high risk for brucellosis was not high in China, and the standardized utilization rate was low, lower than the requirement in National Brucellosis Prevention and Control Plan, and there were significant differences among different areas. It is urgent to distribute PPE to occupational population at high risk for brucellosis and carry out health education about PPE utilization. Meanwhile, it is necessary to strengthen information exchange or sharing among different areas.

Objective To evaluate the efficacy of preoperative electroacupuncture intervention in promoting postoperative gastrointestinal functional recovery by meta-analysis.Methods The databases of PubMed,Cochrane Library,Web of Science,Embase,CBM,CNKI,VIP,and WanFang were searched systematically.The search period ranged from the inception of the databases to March 2024.Two researchers screened the literature independently,extracted the data,used Cochrane Risk of Bias tools to evaluate the quality of the inclusion study,and used RevMan 5.3 software for meta-analysis.Results Twelve RCTs were included,with 773 patients.There were 421 patients in the preoperative electroacupuncture group and 352 patients in the control group.The results of the meta-analysis showed that,time to first flatus(SMD=-0.56,95%CI-0.84 to-0.28,P＜0.001),time to first defecation(MD=-6.40 hours,95%CI-9.27 to-3.53,P＜0.001),time to bowel sound recovery(MD=-8.45 hours,95%CI-10.37 to-6.52,P＜0.001),time to first oral feeding(MD=-16.88 hours,95%CI-23.92 to-9.83,P＜0.001),the incidence of PONV(RR=0.75,95%CI 0.57 to 0.98,P=0.04)and length of hospital stay(MD=-0.78 d,95%CI-1.38 to-0.19,P=0.010)were significantly lower than the control group.Conclusion Electroacupuncture intervention before operation can effectively promote the recovery of post-operative exhaust,defecation,and bowel sound,shorten the time of fasting and drinking,reduce the inci-dence of PONV,shorten the length of hospital stay,and has good clinical value in promoting the recovery of postoperative gastrointestinal function.

Objective:To investigate the clinicopathological features and genetic characteristics of congenital cystic adenomatoid malformation (CCAM) of lung and CCAM associated lung cancer in adults.Methods:A total of 13 cases of CCAM of lung in adults, diagnosed from June 2015 to May 2023, were collected from the Department of Pathology, Shanghai Pulmonary Hospital, Tongji University School of Medicine, China. Their histopathological features were correlated with probable development into lung cancer. Next-generation sequencing was performed on the benign and malignant areas of all cases.Results:The pathological classification of all cases were of CCAM of lung type 1. There were 4 male and 9 female cases, age ranged from 18 to 65 years, with a mean age of 41 years. Six cases were accompanied by lung cancer, all of them were mucinous adenocarcinoma. Next-generation sequencing showed no gene mutation in 2 of the 13 cases; KRAS mutations in exon 2 were detected in 7 cases, in which there were 6 cases complicated with lung mucinous adenocarcinoma and no matter in the malignant or benign regions, the same case exhibited the same mutation sites in KRAS gene.Conclusions:CCAM of the lung is a congenital disease, and in adults, type 1 is most commonly found in the pathological classification, and it is often accompanied by cancer. Gene mutations are frequently detected in CCAM of the lung, KRAS being the most recurrent mutation which may play an important role in the carcinogenesis.

Objective To investigate the correlation between lipid-related index and diabetic kidney disease(DKD)by observing the expression levels of lipid-related index in different stages of DKD.Methods A total of 265 patients with type 2 diabetes mellitus(T2DM)were divided into the T2DM group(n=106)and the DKD group(n=159).According to estimated glomerular filtration rate(eGFR)level,the DKD group was sub-divided into the DKD-G2 group(n=59),the DKD-G3 group(n=59)and the DKD-G4 group(n=41).Data of triglycerides(TG),total cholesterol(TC),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),apolipoprotein A(Apo A),Apo B and urinary albumin/urinary creatinine ratio(UACR)were collected.Gomerular filtration rate(eGFR),triglyceride-glucose index(TyG),visceral adiposity index(VAI)and atherogenic index of plasma(AIP)were calculated.The differences of TyG,VAI and AIP between different groups and their correlation with eGFR and UACR were analyzed.Multiple linear regression analysis of DKD renal injury factors was conducted.Receiver operating characteristic(ROC)curves were drawn to evaluate the predictive efficiency of TyG,VAI,and AIP.Results The levels of TyG,VAI and AIP were significantly higher in the DKD group compared to the T2DM group,and these indices exhibited an increasing trend with disease progression(P＜0.05).Furthermore,there was a negative correlation between TyG,VAI,AIP and eGFR(r=-0.396,-0.425,-0.519,P＜0.01),and a positive correlation between UACR and eGFR(r=0.482,0.479 and 0.583,P＜0.01)in DKD patients.Multiple linear regression results showed that VAI and AIP were independent risk factors for eGFR,and TG,HDL-C,LDL-C,Apo B and VAI were influencing factors of UACR(P＜0.05).The ROC curve analysis revealed that the areas under the curves for TyG,VAI and AIP were 0.902(0.866-0.937),0.969(0.953-0.986)and 0.958(0.937-0.979)respectively.Conclusion The levels of TyG,VAI and AIP are correlated with the progression of DKD,and have predictive value for the occurrence and development of DKD.These biomarkers can be used as a biological indicator to evaluate the occurrence and development of DKD.
