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 analyze the alternative splicing (AS) events of patients with thyroid carcinoma (THYC) and explore the correlation between AS events and the prognosis of THYC.Methods:The clinical data and the Percent Splice In (PSI) value of AS events of THYC were downloaded from The Cancer Gene Atlas (TCGA) database and the TCGA SpliceSeq database respectively. The occurrence of seven kinds of AS events including AA, AD, AF, AP, ME, ES and RI in THYC was investigated and the matrix of AS events and survival data was constructed. Univariate Cox regression analysis was used to screen AS events related to prognosis of THYC. To avoid over-fitting, the least absolute shrinkage and selection operator (LASSO) regression analysis was performed. Then Multivariate Cox regression analysis was used to construct prognosis model. Kaplan-Meier curve and receiver operating characteristic (ROC) curve were performed to evaluate the prognosis ability of the risk model. We also used Pearson correlation analysis to select splicing factors (SF) which were correlated with survival associated AS events. Above SF genes were enrolled to gene ontology (GO) enrichment and KEGG pathway analysis.Results:A total of 10 447 genes and 45 150 AS events in 507 THYC patients were found in the present study. Among them, ES was the main type (38.84%) and ME was the type with the least frequency (0.51%). Totally 1 842 AS events associated with prognosis of THYC patients were identified. Three AS events including USHBP1-48249-AA、CACNB1-40626-AT and BEX5-89679-AP were selected to construct the prognosis model. The risk score of 0.807 was indicated as the best cut-off value of prognosis model. The patients were divided into high-risk group (240 cases) and low-risk group (241 cases) based on the risk score. The results demonstrated that the risk model could be used as a valuable prognostic factor for THYC ( P<0.001, AUC=0.929). The SF-AS network was constructed and several SF genes, including CDK12, RBM25, DDX39B, SRRM2 and DDX46 were identified as hub genes. Conclusions:The risk model based on 3-AS events was valuable prognosis predictor of THYC. The SF-AS network provided new insight for the exploration of tumorigenesis and development of THYC.

Objective:To examine the effects of heart rate control during hospitalization on short-term prognosis of heart failure in elderly patients.Methods:As a prospective study, 150 elderly patients with heart failure were selected from the Department of Geriatrics, Qilu Hospital of Shandong University.The subjects were divided into an experimental group and a control group by digitally generated random numbers, with 75 individuals in each group.Both groups received conventional anti-heart failure therapy during hospitalization, but patients from the control group had doses of heart rate control drugs adjusted every 2-4 weeks, with no special requirement for the heart rate before hospital discharge.In contrast, patients from the experimental group were given heart rate control drugs with timely dose adjustment to achieve more proactive heart rate control, aiming for a rate <70 beat/min, as long as heart failure symptom improvement and good volume management could be maintained.Values of cardiac function indexes were compared between the two groups at discharge and 6 months after discharge.Heart failure readmission rates within 6 months, cardiovascular disease mortality rates and the incidences of composite endpoint events after readmission due to heart failure aggravation were compared between the two groups.Treatment safety was also evaluated.Results:There was no statistical difference in blood pressure, heart rate, N-terminal pro-B-type natriuretic peptide(NT-pro-BNP), left ventricular ejection fraction(LVEF), left ventricular end systolic diameter(LVESD), or left ventricular end diastolic diameter(LVEDD)between the two groups at admission( P>0.05), and there was no statistical difference in the average length of hospitalization between the two groups( P>0.05). The experimental group had a lower average heart rate and diastolic pressure than the control group at discharge and 6 months latter[at discharge: (61.6±4.2)beat/min(1 mmHg=0.133 kPa) vs.(78.0±7.1)beat/min, (62.1±10.4)mmHg vs.(66.1±10.2)mmHg; at 6 months: (64.7±12.1)beat/min vs.(71.8±11.2)beat/min, (62.8±11.2)mmHg vs.(68.6±10.2)mmHg; P<0.05 or P<0.01]. NT-pro-BNP in the experimental group was significantly lower than that in the control group at discharge[(1 706±1 408)ng/L vs.(2 806±3 812)ng/L, P<0.05]. The absolute values of changes in LVEF(ΔLVEF), LVESD(ΔLVESD)and LVEDD(ΔLVEDD)after 6 months in the experimental group were significantly higher than those in the control group[ΔLVEF: (0.08±0.09) vs.(0.02±0.09), P<0.05; ΔLVESD: (-5.82±7.44)mm vs.(-1.63±6.07)mm, P<0.01; ΔLVEDD: (-2.76±5.52)mm vs.(-0.86±4.44)mm, P<0.05]. The rate of readmission and the incidence of composite endpoint events within 6 months in the experimental group were significantly lower than those in the control group[21.3%(16 cases) vs.36.0%(27 cases), P<0.05]; 25.3%(19 cases) vs.44.0%(33 cases), P<0.05.There was no significant difference in all-cause mortality between the two groups( P>0.05). Conclusions:For elderly patients with heart failure, proactive active heart rate control during hospitalization and a rate <70 beat/min before discharge will improve cardiac function indexes and lower the rate of readmission with exacerbation of heart failure, cardiovascular disease mortality and the incidence of composite end-point events after readmission.This strategy has good safety and is beneficial for short-term prognosis.
