Meta-analysis of clinical efficacy and safety of Compound Danshen Dripping Pills combined with conventional antihypertensive drugs in treatment of hypertensive left ventricular hypertrophy / 中国中药杂志

To systematically evaluate the clinical efficacy and safety of Compound Danshen Dripping Pills combined with conventional antihypertensive drugs in the treatment of hypertensive left ventricular hypertrophy. China National Knowledge Infrastructure(CNKI), Wanfang, VIP, PubMed, EMbase, Cochrane Library, Ovid and Web of Science databases were searched by computer to retrieve the randomized controlled trials(RCTs) of Compound Danshen Dripping Pills combined with conventional antihypertensive drugs in the treatment of hypertensive left ventricular hypertrophy from the establishment of databases to July 2020. After two researchers performed data retrieval, data extraction, and risk assessment of bias, they used RevMan 5.3 software for Meta-analysis. A total of 10 RCTs were included, with a total of 979 patients. Meta-analysis results showed that in terms of interventricular septal thickness(MD=-0.70, 95%CI[-1.15,-0.24], P=0.003), left ventricular posterior wall thickness(MD=-0.81, 95%CI[-1.41,-0.21], P=0.008), left ventricular mass index(MD=-8.75, 95%CI[-17.40,-0.10], P=0.05), systolic blood pressure(MD=-8.97, 95%CI[-13.46,-4.48], P<0.000 1), diastolic blood pressure(MD=-5.87, 95%CI[-8.39,-3.34], P<0.000 01) and left ventricular end-diastolic diameter(MD=-1.73, 95%CI[-2.38,-1.08], P<0.000 01), Compound Danshen Dripping Pills combined with conventional antihypertensive drugs was superior to conventional antihypertensive drugs. In terms of left ventricular ejection fraction(MD=0.41, 95%CI[-0.74, 1.55], P=0.49), there was no statistical difference in treatment between the two groups. Because of the small amount of literatures included in the safety aspect, it is impossible to give an accurate conclusion. The GRADE score showed that the level of evidence was low and extremely low. The results show that the Compound Danshen Dripping Pills combined with conventional antihypertensive drugs may effectively improve the clinical efficacy for hypertensive ventricular hypertrophy, and the safety needs to be further explored. Due to the low quality of the included literatures, more high-quality RCTs are needed for verification.

The successfully modeled rats were then randomly divided into model group （equal volume of normal saline）， modified Shengjiangsan group （27.3 g·kg^-1） and benazepril group （10 mg·kg^-1）， with corresponding drug dosage once a day for 4 weeks of continuous intervention. After drug administration， the 24-hour urine protein （UTP） was detected. Real time fluorescent quantitative polymerase chain reaction （Real-time PCR） and immunohistochemical （IHC） methods were used to detect Podocalyxin， Nephrin， Podocin， Synaptopodin mRNA and protein expression levels in rat kidney tissue. terninal-deoxynucleoitidyl transferase medsated nick and labeling （TUNEL） method was used to detect cell apoptosis rate in rat kidney tissue， and Western blot was used to detect Notch1， Hes1， B lymphoblastoma-2 （Bcl-2） associated X protein （Bax）， and Bcl-2 protein expression levels in rat kidney tissue. Result:Compared with the normal group， UTP in the model group increased significantly， renal tissue cell apoptosis increased significantly， podocyte marker proteins podocalyxin， Nephrin， Podocin， Synaptopodin mRNA and protein expression levels decreased significantly， and Notch1， Hes1， Bax protein expression increased significantly， and Bcl-2 protein expression was significantly reduced（<italic>P</italic><0.05）. Compared with the model group， UTP levels in MN rats were significantly reduced in modified Shengjiangsan and benazepril groups， with reduced rate of renal cell apoptosis， increased mRNA and protein expression levels of podocalyxin， Nephrin， Podocin， and Synaptopodin in renal tissue， decreased Notch1， Hes1， Bax protein expression， and increased Bcl-2 protein expression（<italic>P</italic><0.05）. Conclusion:Modified Shengjiangsan can inhibit the Notch signaling pathway， reduce the apoptosis of rat kidney tissue podocytes， and reduce the kidney injury of MN rats.

Analysis of traditional Chinese medicine from patent information sharing platform of coronavirus disease 2019 (COVID-19) / 中国中药杂志

Coronavirus disease 2019(COVID-19) is a newly emerged and highly contagious respiratory disease. Traditional Chinese medicine(TCM) has both systematism theory knowledge and clinical practical value in the prevention and treatment of COVID-19. Therefore, it was particularly important to examine the effect of TCM in the prevention and treatment of COVID-19. The patents of TCM might reflect the latest progression of scientific research. We aimed to provide reference for the prevention and treatment of COVID-19 by extracting and analyzing the TCM patents from the Patent Information Sharing Platform of COVID-19. The antiviral TCM patents were screened and exported from the Patent Information Sharing Platform. VOSviewer 1.6.14 was used to visualize and analyze the network of TCM in these patents. There were total 292 TCM patents, including 52 patents for etiological treatment and 240 patents for symptomatic treatment. Thirty-two provinces and 1 076 inventors were involved, mainly from Beijing, Guangdong and Jiangsu. Overall, there were 356 TCMs, 71 single prescriptions, and 221 compound prescriptions. The patents for treatment of coronavirus mainly focused on the treatment of coronavirus, while the patents for symptomatic treatment mainly focuses on the improvement of respiratory symptoms, such as fever and cough. There were 14 highly frequently used TCMs, including Glycyrrhizae Radix et Rhizoma, Scutellariae Radix, Lonicerae Japonicae Flos, Forsythiae Fructus, Isatidis Radix, Astragali Radix, Menthae Haplocalycis Herba, Gypsum Fibrosum, Houttuyniae Herba, Isatidis Folium, Rhei Radix et Rhizoma, Gardeniae Fructus, Platycodonis Radix, Armeniacae Semen Amarum. The analyzed results of the TCM patents from the patent information sharing platform of COVID-19 were consistent with the Guideline of Diagnosis and Treatment of COVID-19(7th edition), and the combination of TCM in each cluster may also provide future directions for drug compatibility.

Tongmai Yangxin Pills in treatment for angina pectoris of coronary heart disease: a systematic review of randomized clinical trails / 中国中药杂志

To systematically review the efficacy and safety of Tongmai Yangxin Pills in treatment for angina pectoris of coronary heart disease. CNKI, WanFang, VIP, SinoMed, PubMed, EMbase and the Cochrane Library databases were retrieved online to collect randomized controlled trials(RCTs) of Tongmai Yangxin Pills for angina pectoris of coronary heart disease since the establishment to November 2018. Two investigators screened out literatures independently, extracted data and assessed the risk of bias of included studies. The risk assessment of included references was made according to criteria recommended by Cochrane Handbook 5.3. Meta-analysis was then performed by RevMan 5.3 software. A total of 9 RCTs were included. The results of Meta-analysis showed that compared with the single application of chemotherapy, the combined administration with Tongmai Yangxin Pills and Western medicine could significantly improve the clinical efficacy of angina(RR=1.22, 95%CI[1.13, 1.31]), the improvement rate of electrocardiogram(RR=1.31, 95%CI[1.21, 1.42]), and the clinical efficacy of traditional Chinese medicine(TCM) syndrome(RR=1.17, 95%CI[1.02, 1.35]). Only one study reported adverse events, while 5 studies reported no adverse event. According to current evidences, in the treatment of angina pectoris of coronary heart disease, Tongmai Yangxin Pills has a better clinical efficacy in the treatment of angina pectoris of coronary heart disease in terms of the improvement rate of electrocardiogram and the clinical efficacy of TCM syndrome. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.

We searched CNKI, WanFang, SinoMed, PubMed, EMbase, and The Cochrane Library from the inception to January 3 2018, to collect the randomized controlled trials（RCTs）on Chinese patent medicines with resolving hard lump function in treating cyclomastopathy. Two reviewers independently screened literature, extracted data and assessed the methodological quality of included studies. Then, statistical analysis was performed by using Stata 12.0 and WinBUGS 1.4.3 software. A total of 52 RCTs involving 9 605 patients were finally included. The inventions included 11 commercial Chinese patent medicines with functions of resolving hard lump, such as Rupi Sanjie Capsules, Xiaoru Sanjie Capsules, Ruhe Sanjie Pills, and Hongjin Xiaojie Capsules. The result of direct Meta-analysis showed that: as compared with the simple western medicine group, the Chinese patent medicines such as Hongjin Xiaojie Capsules, Ruhe Sanjie Pills, Rupi Sanjie Capsules, Xiaoru Sanjie Capsules and Xiakucao Oral Liquid could significantly improve the clinical efficacy. In addition, the incidence of adverse reactions of Chinese patent medicines with resolving hard lump function was lower than that in Western medicine group in gastrointestinal reactions, menstrual disorders, leucorrhea abnormalities, liver dysfunction and estrogen-like effect. The network Meta-analysis showed that: Xiaoru Sanjie Capsules, Ruhe Sanjie Pills, Yanlu Rukang Capsules, Quyu Sanjie Capsules, and Hongjin Xiaojie Capsules were the top five in terms of treatment effect. Chinese patent medicines with resolving hard lump function had better clinical efficacy. Due to the low quality of included studies， more high quality RCTs are needed to verify the above conclusion.

Network Meta-analysis of Chinese medical injections for heart failure / 中国中药杂志

To assess the clinical efficacy of Chinese medical injection (CMI) for heart failure by using network Meta-analysis method. The relative randomized controlled trials (RCTs) of CMI for heart failure were retrieved from China National Knowledge Infrastructure (CNKI), WanFang Database, Chinese Biomedical Literature Database (SinoMed), PubMed, Cochrane Library and EMbase in July 2017. RCTs on the comparison of two kinds of CMIs for heart failure were included. Two researchers independently completed the literature screening, data extraction and quality evaluation according to the pre-determined inclusion and exclusion criteria, and the results were crossed checked. The data were analyzed by Win Bugs, and STATA software was used for plotting. Finally, 13 RCTs were included, involving 5 kinds of CMIs and 1 538 patients. According to the quality evaluation, the appropriate random dividing methods were reported in only two RCTs, double-blindness was used in only one RCT, and even none of the RCTs mentioned allocation concealment. Network Meta-analysis showed that Shenmai injection had the greatest effect in the clinical efficacy for patients with heart failure, which was followed by Shenfu Injection. However, Shenfu Injection was most effective in improving the patients' left ventricular ejection fraction (LVEF), which was followed by Shenmai Injection. Therefore, Shenfu Injection and Shenmai Injection had certain advantages in treating heart failure. However, due to the limited sample size and the poor literature quality, more studies were required to verify the strength of evidence. We suggest that further studies shall pay more attention to the improvement of the methodological quality, increase the follow-up period, and strengthen the observation of cardiovascular end points.
