Objective To observe the effect of JWSNS serum on proliferation and apoptosis hepatic stellate cells.Methods After being added different concentrations of JWSNS (the low concentrations of JWSNS:0.78 g/ml of crude drug; the medium concentration group of JWSNS:1.56 g/ml of crude drug; the high concentration group of JWSNS:3.12 g/ml of crude drug) drug-containing serum in vitro HSC-T6 cells for 12h,24 h and 48 h respectively,detected serum HSC-T6 proliferation with MTT colorimetry method and measured HSC-T6 apoptosis with flow cytometry and TUNEL method.Results (①) After applied JWSNS on rats HSC-T6,the Cell proliferation was inhibited which showed a time-concentration dependence.The differences were significant when comparing each JWSNS group with the control group (P＜0.01).High concentration of JWSNS group showed significant difference when compared with Biejiaruangan tablets group (P＜0.05) with high concentration of JWSNS (0.399± 0.041) ％ after 48h,and Biejia-Ruangan tablets (0.429± 0.037) ％ after 48 h.② Flow cytometry analysis showed each JWSNS group and Biejiaruangan tablets group had significant increased cell apoptosis when compared with the control group (P＜0.05) after 12 h,24 h,and 48 h.JWSNS medium concentration group [12 h was (17.83±0.25)％,24 h was (26.06±0.26)％,48 h was (39.30±2.25) ％] and JWSNS high concentration group [12 h was (27.15±0.29)％,24 h was (38.96±0.51)％,48 h was (49.34± 0.77) ％] had a significant increased cell apoptosis compared to the Biejia-Ruangan tablets group [ 12 h was (8.31 ± 0.30) ％,24 h was (16.25 ± 0.25) ％,48 h was (27.12± 0.39) ％].③ TUNEL detection showed that each concentration of JWSNS group [the low concentration of JWSNS:was (25.1 ± 1.48)％,medium concentration group of JWSNS was(39.30±2.25)％,high concentration group of JWSNS was(39.30±2.25)％] had a significant increased cell apoptosis rate than Biejiaruangan tablets group (30.0± 3.92) after 48 h (P＜0.01).Conclusion JWSNS containing serum can inhibit the proliferation of HSC-T6 in vitro,promote the apoptosis

Objective To investigate the role of Jiawei-sini Dection on expression of rat transforming growth factor-β1 receptor Ⅰ,Ⅱ(TβRⅠ,TβR Ⅱ), and study its treatment of anti-HF and the possible mechanisms. Methods The model of rat hepatic fibrosis was setup by subcutaneous injection of carbon tetrachloride and drinking alcohol freely;According to random block method, the successful model rats were divided into three groups:pathological model group (group B),Fufangbiejiarangan tablet group (group C), and Jiawei Sini Decoction group (group D), each group containing ten rats. Group A and group B were given two milliliters saline, group C was given Fufangbiejiarangan tablets 0.625 grams per kilogram of body weight, group D was given Jiawei Sini liquid 15.625 grams per kilogram of body weight.Each rat was fed once a day for 8 weeks.In order to avoid the natural repair of the hepatic affecting the experimental results, the rats,except group A, were still injected 40% CCl4 three milliliters per kilogram of body weight after feeding drug once a week. Fufang-Biejia-Ruangan Ttablet group was set as a positive control;The effects on expression of TβRⅠ,TβR Ⅱ were determined by immunohistochemical method. Changes of alanine aminotransferase (ALT), aspartate aminotransferase(AST),alkaline phosphatase(ALP) and TβRⅠ,TβR Ⅱ were observed in rats. Results The expression of TβRⅠ、Ⅱ, compared with the pathological model(16.63±2.69)%, (14.57±1.09)%, were significantly reduced in Jiawei-Sini Dection group[they are(8.09±0.71)%,(6.51±0.48)%, the difference was statistically significant(P＜0.05).The effects of Jiawei-Sini Dection was equal to the effect of Fufang-Biejia-Ruangan Tablets on expression of TβRⅠ,TβR Ⅱ(P＞0.05). Conclusion Jiawei-Sini Dection was able to inhibit the expression of TβRⅠ and TβR Ⅱ, thus affected the combination of TGFβ1, and their receptors.

Objective:To explore the causal relationship between gut microbiota and lung function (FEV1/FVC) using two-sample Mendelian randomization method; To explore its application in the TCM field.Methods:This was a Mendelian randomization study. The GWAS data of gut microbiota from the MiBioGen consortium study and the GWAS data of lung function (FEV1/FVC) published by IEU OpenGWAS in the public database were used, and instrumental variables were extracted according to prespecified thresholds. The inverse variance weighted method (IVW) was mainly used for analysis. The results were evaluated according to the effect indicator β value and 95% CI. When the IVW method was statistically significant, further sensitivity analysis was performed. Leave-one-out test, heterogeneity test, horizontal gene pleiotropy test and MR-Egger regression intercept analysis were used to verify the stability and reliability of the results. Results:A total of 10 causal relationships between gut microbiota and lung function (FEV1/FVC) were determined using the IVW method: family. BacteroidalesS24.7group ( β=-0.029, P=0.015), family. ClostridialesvadinBB60group ( β=-0.028, P=0.040), family. Streptococcaceae ( β=-0.056, P=0.042), genus. LachnospiraceaeFCS020group ( β=0.025, P=0.029), genus. Lactococcus ( β=-0.024, P=0.038), genus. Peptococcus ( β=0.025, P=0.049), genus. RuminococcaceaeUCG011 ( β=-0.030, P=0.038), genus. Ruminococcus2 ( β=0.028, P=0.033), genus. Terrisporobacter ( β=-0.030, P=0.018), phylum. Cyanobacteria ( β=0.027, P=0.039). Leave-one-out analysis showed that the results were stable, and the effects of heterogeneity and horizontal gene pleiotropy on causal effect estimation could be removed. Conclusion:The gut microbiota may play a role in the changes of lung function, which to a certain extent confirms the TCM theory of "exterior-interior relationship between the lung and large intestine", and can provide certain reference for the research direction of TCM.

ObjectiveTo analyze the distribution of traditional Chinese medicine （TCM） patterns as well as factors related to acute exacerbation in group E of chronic obstructive pulmonary disease （COPD）. MethodsThe general data of 161 COPD patients， including gender， age， body mass index （BMI）， disease course， smoking history， and past history， were collected. In terms of the four examinations of TCM， the differentiated patterns included phlegm-heat obstructing the lung， turbid phlegm obstructing the lung， phlegm stasis obstructing the lung， lung-spleen qi deficiency， and lung-kidney deficiency. The modified British Medical Research Council （mMRC） scale and COPD assessment test （CAT）， the pulmonary function indicators including forced expiratory volume in the first second （FEV1） and ratio of forced expiratory volume to forced vital capacity at second 1 （FEV1/FVC）， GOLD grade， and the patient's acute exacerbations in the previous year were recorded. Multivariate regression analysis was performed using logistic regression model to determine the relevant factors of patients in COPD group E. The distribution of acute exacerbations in different TCM symptom patients in group E was analyzed. ResultsThere were 80 patients （49.69%） in group E and 81 patients （50.31%） in non-group E. In group E， 23 （28.75%） patients had a history of two acute exacerbations， while 35 （43.75%） had three acute exacerbations， and 22 （27.5%） had more than three acute exacerbations. There were 13 （16.25%） cases of phlegm-heat obstructing the lung pattern， 6 （7.5%） cases of turbid phlegm obstructing the lung pattern， 8 （10%） cases of phlegm stasis obstructing the lung pattern， 22 cases （27.5%） of lung-spleen qi deficiency pattern， and 31 （38.75%） cases of lung-kidney deficiency pattern. There were significant differences in smoking history， disease course， TCM pattern， TCM syndrome score， mMRC score， and CAT score between groups （P＜0.05）. A total of 107 of the 161 patients completed pulmonary function tests， and the differences in FEV1， FEV1/FVC and GOLD grades between groups were statistically significant （P＜0.05）. Multivariate regression analysis showed that TCM pattern， TCM syndrome score and CAT score were statistically significant factors for COPD patients in group E （P＜0.05）. There were statistically significant differences in the number of acute exacerbations in different TCM patterns in group E （P＜0.05）. The patients with two acute exacerbations in the past year were mainly phlegm-heat obstructing the lung and lung-spleen qi deficiency patterns， while the three acute exacerbations were mainly seen in lung-spleen qi deficiency and lung-kidney deficiency patterns， and more than three exacerbations were more common with lung -kidney deficiency pattern. ConclusionsPatients in COPD group E were mainly the lung-spleen qi deficiency and lung-kidney deficiency patterns. Deficiency of healthy qi is the main reason for the increase in the number of acute exacerbations， and TCM patterns and CAT score were the main related factors.
