【Objective】 To investigate the effects of formononetin (FMN) on cardiomyocyte apoptosis and HSP90/AKT in rats with dilated cardiomyopathy-mediated heart failure. 【Methods】 Echocardiography, ELISA, histological staining, and TUNEL staining were used to observe the protective effect of different doses of FMN on dilated cardiomyopathy-mediated heart failure in rats and the apoptosis of cardiomyocytes. The potential targets of formononetin on dilated cardiomyopathy-mediated heart failure were obtained from TCMSP, DisGeNet, GeneCards, and other databases, the key targets were obtained according to the protein-protein interaction (PPI) network, and the key targets were verified by molecular docking. Western blotting was used to further verify the regulatory role of key targets in the treatment of dilated cardiomyopathy-mediated heart failure with formononetin. 【Results】 Formononetin could reduce the levels of LVIDS, LVIDD, NT-pro BNP, cTn-T, CK, CK-MB, and LDH in rats with dilated cardiomyopathy-mediated heart failure, increase the levels of EF and FS, and reduce the apoptosis of cardiomyocytes. FMN had a strong binding effect on 10 key targets (AKT1, HSP90AA1, CASP3, MAPK1, MMP9, SRC, ALB, HRAS, IGF1, and EGFR) screened by network pharmacology, with HSP90AA1 and AKT1 having the strongest binding effect. Formononetin decreased the expression of HSP90, AKT and downstream CASP3 protein, but increased the expression of p-AKT in myocardial tissue. 【Conclusion】 Formononetin may inhibit the expression of HSP90, promote phosphorylation of AKT to p-AKT, and inhibit the expression of CASP3, thereby reducing the apoptosis of cardiomyocytes and improving myocardial tissue damage, so as to achieve the purpose of treating dilated cardiomyopathy-mediated heart failure.

OBJECTIVE: To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding. METHODS: A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle. RESULTS: A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P>0.05). CONCLUSION The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients.

Aim To study the electrophysiological mechanism of dopamine inhibiting insulin secretion hv voltage-dependent potassium ( Kv) channels.Methods Islets and (3 cells were isolated from male SD rats.D,-like receptor agonist ( SKP38393), D2-like receptor agonist (Quinpirole) and antagonist (Epiclopride) were used according to the experiment.Insulin secretion was detected by insulin radioimmunoassay.Whole-cell j J patch-clamp technique was applied to detect Kv channel currents and action potential duration of p cells.Di- BAC4(3) staining was used to observe membrane potential.Results SKF38393 did not affect insulin secretion and the Kv channel currents.Quinpirole signifi cantly inhibited insulin secretion and increased Kv channel currents.Dopamine significantly inhibited insulin secretion, increased Kv channel currents and shortened action potential duration of p cells, which could be reversed by epiclopride.In addition, dopamine de-creased membrane potential of INS-1 cells.Conclusions Dopamine inhibits insulin secretion by acting on D2-like receptors, resulting in actived Kv channels, shortened action potential duration and decreased cell membrane potential.

OBJECTIVE: To observe the clinical effect of platelet rich plasma (PRP) combined with β tricalcium phosphate bioceramic bone in the treatment of non traumatic necrosis of the femoral head in ARCO stageⅡ. METHODS: From January 2017 to December 2018, 100 patients (160 hips) with ARCO stageⅡnon traumatic necrosis of the femoral head were divided into PRP group and control group. In PRP group, 50 patients (80 hips), 22 males and 28 females, aged from 18 to 65 (43.47± 7.23) years, with a course of 4 to 18 (15.8±2.9) months, underwent core decompression and bone grafting combined with PRP implantation. There were 50 cases (80 hips) in the control group, including 27 males and 23 females, aged 20 to 63 (45.72± 7.43) years, and the course of disease was 6 to 19 (14.9±3.8) months. Hip X-ay film was followed up after operation. Harris score and VAS score were used to evaluate the curative effect, and the survival rate of hip joint was recorded. RESULTS: All patients had good wound healing, no infection, thrombosis and other complications. All patients were followed up for 12 to 14 (12.0±0.4) months. Twelve months after operation, the image expression of PRP group was better than that of control group( CONCLUSION Platelet-rich plasma(PRP) combined with artificialbone for core decompression and bone grafting can change the situation of simple artificial bone implantation and uncertain curative effect, improve the success rate of this operation, effectively reduce the collapse rate of femoral head necrosis in the early and middle stage, delay or even avoid hip replacement.

BACKGROUND: Knee osteoarthritis (OA) is a major cause of disability among the older adults. Few treatments are safe and effective. Moxibustion is commonly used in treating knee OA in Chinese medicine (CM). CO Laser moxibustion device is a substitute for traditional moxibustion, which mimics the effects of traditional moxibustion. More data are needed to support its application in knee OA. OBJECTIVE: ObjectiveThe trial aims to assess the effect and safety of CO laser moxibustion in patients with knee osteoarthritis compared with a sham control. METHODS: This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial. A total of 392 participants were recruited and assigned to the CO laser moxibustion group and sham laser moxibustion group with a 1:1 ratio at 6 outpatient clinics in Shanghai, China. Participants in both groups received treatment at the affected knee(s) at the acupuncture point Dubi (ST 35) and an Ashi point. There were 3 sessions per week for 4 weeks, and an additional 20-week follow-up. Primary outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores at week 4. Secondary outcomes were WOMAC function score, stiffness score and overall score, VAS pain, Short-Form heath survey (SF-36), and patients' global assessment. The serum levels of cytokines involved in progress of knee OA were explored. Safety was assessed during the whole trial. Masking effectiveness was assessed by both participants and treatment providers.This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial.

OBJECTIVETo investigate expression features and correlation of genes expression on MyD88-dependent signaling pathway in synovial membrane (SM) of progression of knee osteoarthritis (OA).

METHODSSixty Wistar rats were randomly divided into 6 groups, including blank group (N), false surgical group, model groups[2 weeks (2W), 4 weeks (4W), 8 weeks (8W) and 12 weeks (12W)], with 10 rats in each group. The models were established by using Hulth method. Control group was experienced no surgery, while false surgical group was only opened joint cavity and sutured. The SM samples was collected according to the time designed above. The relative expression quantity of MyD88, TLR4 and NF-κB was detected by Real-time PCR after the extraction of the total RNA and reverse transcription. The correlation analysis was obtained by SPSS.

RESULTSThere was no significant difference in each gene mRNA expression between false surgical and blank group(> 0.05), while enhanced expression was found in the model groups(<0.05). The correlation index among MyD88, TLR4 and NF-κB was 0.91 and 0.86 respectively, and had significant difference among them.

CONCLUSIONSPositively relative among MyD88, TLR4 and NF-κB played main role in TLR4/NF-κB signal passway, and could predicate the expression of other genes in the passway. It also could further provide the basis for clarify the pathologic mechanism of knee OA.
