Aim To explore the signaling pathway of matrine derivative ZS10 in inhibiting proliferation and inducing apoptosis of BEL-7402 cells. Methods ZS10 was synthesized by organic synthesis. The inhibitory effect of ZS10 on the proliferation of BEL-7402 cells was analyzed by MTT method at the time of 24 h, 48 h and 72 h, respectively, and IC50 was calculated. DAPI staining was used to observe the state of BEL-7402 cells. Clone formation method was used to observe the colony formation of BEL-7402 cells, flow cytometry was used to observe the cell cycle arrest and apoptosis of BEL7402 cells, and Western blot was used to detect the expression level of PI3K/AKT pathway and related proteins. Results MTT results showed that the IC50 was(6.62±1.11)μmol·L-1; DAPI staining showed that the cell state changed significantly with the increase of drug concentration, and the results of colony formation showed that ZS10 significantly inhibited the colony formation of BEL-7402 cells. The results of flow cytometry showed that ZS10 induced S phase arrest and cycle apoptosis of BEL-7402 cells. Western blot showed that ZS10 at the concentration of 08 μ mol·L-1 could regulate the PI3K/AKT pathway and its related proteins in a dose-dependent manner. Compared with the control group, the expression of PI3K, AKT, P-AKT and anti-apoptotic protein Bcl-2 significantly decreased, the expression of pro-apoptotic protein Bax significantly increased, the expression of Cyclin D1 and CDK2 significantly decreased, and the expression of EGFR and N-cadherin, Vimentin significantly decreased in the treatment group. The expression of E-cadherin increased. Conclusions Matrine derivative ZS10 can inhibit the growth and proliferation of hepatocellular carcinoma cell line BEL-7402.

Shouhui Tongbian Capsules was used to explore the therapeutic effect and potential mechanism on slow transit constipation model mice induced by loperamide hydrochloride. In the experiment, loperamide hydrochloride-induced ICR mice were used as the model of slow transit constipation. Fifty ICR mice were divided into the blank group, model group and high, medium and low dose groups of Shouhui Tongbian Capsules extract(100, 200 and 400 mg·kg~(-1)). The model group and the administration groups were then modeled using loperamide hydrochloride intragastrically to obtain slow transit constipation. After successful modeling, high, medium and low doses of drugs were given to each drug group by intragastric administration. After 14 days of administration, the first defecation time, 6 h defecation grain number, 6 h defecation wet weight and dry weight, black feces discharged within 6 h and the fecal water content were measured. Intestinal tissues were taken for c-Kit and SCF immunohistochemical sections to detect the expression of c-Kit and SCF in the blank group, model group and high, medium and low dose groups of the medicinal extract of Shouhui Tongbian Capsules. The tissue changes in the intestinal wall of mice were detected by HE staining. At the same time, partial intestinal tissues were taken to test the activity of ATP synthase and isocitrate dehydrogenase in intestinal tissues of mice. RESULTS:: showed that Shouhui Tongbian Capsules effectively improved the symptoms of slow transit constipation in ICR mice and promoted intestinal movement. Shouhui Tongbian Capsules obviously shortened the time of discharging black stool for the first time, improved the intestinal propulsion rate, increased the water content and amount of feces, and improved the constipation symptoms. Mechanism study revealed that Shouhui Tongbian Capsules increased ATP synthase activity and mitochondrial isocitrate dehydrogenase activity in intestinal tissue, and up-regulated c-Kit/SCF signaling pathway to promote interstitial Cajal cells proliferation, intestinal nerve transmission, intestinal motility and transport capacity.

To evaluate the efficacy and safety of Chinese patent medicine in the treatment of knee osteoarthritis(KOA) with network Meta-analysis, and provide evidence-based medicine evidences for clinical practice. PubMed, Cochrane Library, EMbase, CNKI, Wanfang, VIP and CBM were used to search for clinical randomized controlled trials(RCTs) on Chinese patent medicines for treatment of knee osteoarthritis, with a time limit from the establishment of each database to March 2020. The bias risk assessment tool recommended by Cochrane was used to evaluate the quality of the included RCTs. The network Meta-analysis was performed by Stata 14.0 software. A total of 5 788 patients in 58 RCTs were included, involving 9 kinds of Chinese patent medicines. The results of the network Meta-analysis indicated that in terms of total effective rate, the top three optimal medication regimens were Jinwu Gutong Capsules + Amino Acid Glucose(AAG), Xianling Gubao + AAG and Biqi Capsules; the top three interventions to reduce the VAS score were Panlongqi Tablets > Xianling Gubao + AAG > Xianling Gubao + non steroidal anti-inflammatory drugs(NSAIDs); the top three interventions to reduce the total score of WOMAC were Jintiange Capsules+NSAIDs> Jinwu Gutong Capsules + AAG > Biqi Capsules + NSAIDs; the top three medication schemes with better curative effect to reduce Lequesnse index were Xianling Gubao + NSAIDs > Biqi Capsules + NSAIDs > Jintiange Capsules + NSAIDs; the top three interventions to reduce TNF-α level Xianling Gubao + AAG > Jintiange Capsules > Jintiange Capsules + AAG=Jinwu Gutong Capsules + AAG. In terms of safety, the top five interventions with the least adverse reactions were Biqi Capsules > Jinwu Gutong Capsules > Biqi Capsules + NSAIDs > Xianling Gubao + NSAIDs > Jintiange Capsules. The combined application of Chinese patent medicine and NSADIs or AAG can improve the clinical treatment effect and reduce adverse reactions in KOA patients.

Objective:To investigate the clinical efficacy of Shashen Maidongtang plus total glucosides of paeony capsule on primary Sjogren's syndrome (pSS) based on the theory of fluid metabolism. Method:In this study, 84 patients of Qi-Yin deficiency type pSS admitted in Zhengzhou Chinese Medicine Hospital from January 2018 to January 2019 were divided into observation group (42 cases) and control group (42 cases) on the basis of random number table. The control group was orally given total glucosides of paeony capsule and iguratimod tablet, while the observation group was orally given Shashen Maidongtang combined with glucosides of paeony capsule. After 3 months of continuous treatment to all subjects, the clinical efficacy was evaluated, and side effects were recorded. Before and after the treatment, the saliva flow rate and basal tear secretion Schirmer I test (SIt) value were measured, European League Against Rheumatism Sjogren's syndrome patient reported index and Sjogren's syndrome disease activity index (ESSPRI and ESSDAI) were scored, the erythrocyte sedimentation rate (ESR) was determined by Westergren, and the levels of serum rheumatoid factor (RF) and immunoglobulin (Ig) G were tested by immunoturbidimetry and rate scattering turbidimetry, respectively. Result:The overall effective rate of the observation group was 90.48% (38/42), which was much higher than 69.05% (29/42) of the control group (χ²=5.974，P<0.05). After treatment, the saliva flow rates and SIt values of both groups got significantly increased compared with those before the treatment (P<0.05), but the saliva flow and SIt of the observation group were significantly better than those of the control group over the same period after treatment (P<0.05). After treatment, both groups had a great decrease in ESSPRI and ESSDAI scores compared with those before the treatment (P<0.05), and the above scores of the observation group were dramatically lower than those of the control group over the same period (P<0.05). After treatment, ESR, serum RF, and IgG levels of both groups were significantly lower than those before the treatment (P<0.05), and the observation group showed higher levels of ESR, serum RF and IgG than the control group over the same period after treatment (P<0.05). Side effects were few and mild in both groups. Conclusion:In treating patients of Qi-Yin deficiency type pSS, Shashen Maidongtang plus total glucosides of paeony capsule was proven to be effective generally. It could significantly inhibit excessive inflammation and hyperhumoral immunity in patients, and control their disease activity. This may be related to the effect of Shashen Maidong decoction and its decomposed recipes in correcting body fluid infusion and metabolic disorder in patients of Qi-Yin deficiency type pSS.
