Résumé
This study was conducted to evaluate the efficacy and safety of Simotang Oral Liquid in the treatment of functional dyspepsia in adults. "Simotang Oral Liquid" "Simotang" "Si Mo Tang" "Si Mo Tang Oral Liquid" were used for retrieval of the relevant papers from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, Springer Link, and Web of Science from database inception to June 2021. Randomized controlled trial(RCT) of Simotang Oral Liquid in the treatment of functional dyspepsia in adults was screened out for Meta-analysis which was conducted in RevMan 5.3. A total of 16 RCTs were included. Meta-analysis showed that compared with the control group, Simotang Oral Liquid increased the total response rate and lowered the traditional Chinese medicine syndrome scores, serum cholecystokinin(CCK), serum nitric oxide(NO), and incidence of adverse reactions. However, the serum substance P(SP) had no statistical difference between the two groups. Simotang Oral Liquid is effective and safe in the treatment of functional dyspepsia in adults. However, this study has evidence and limitations, so the conclusions need to be further verified by large sample and multicenter clinical studies.

This research was to evaluate the economics of Shexiang Tongxin Dropping Pills combined with conventional therapy for patients with coronary heart disease(CHD) in Chinese medical environment. From the perspective of medical insurance, a Markov model was established in this study based on the results of Meta-analysis comparing the effectiveness and safety of Shexiang Tongxin Dripping Pills combined with conventional treatment and conventional treatment alone. The experimental group was treated with She-xiang Tongxin Dropping Pills combined with conventional Western medicine treatment, while the control group was treated with conventional Western medicine treatment alone. The cost-utility analysis and sensitivity analysis were performed for the two regimens using Treeage pro. After 30 cycles of model simulation, according to the results of Markov model, the total cost and health output were CNY 237 795.73 and 16.36 QALYs(the quality adjusted life years, QALYs), respectively for Shexiang Tongxin Dropping Pills combined with conventional Western medicine treatment, CNY 247 396.55 and 16.36 QALYs respectively for the conventional Western medicine treatment alone. Compared with the conventional treatment alone, the Shexiang Tongxin Dropping Pills combined with conventional treatment had lower long-term cost and higher health output, with advantages of cost-utility and pharmacoeconomic advantages. The sensitivity analysis results showed that the conclusion was relatively stable. Based on the above results, it is considered that compared with the conventional Western medicine alone, Shexiang Tongxin Dropping Pill combined with conventional Western medicine is a treatment regimen with pharmacoeconomic advantages for the treatment of CHD.

The aim of the research was to evaluate the efficacy and safety associated with Shexiang Tongxin Dropping Pills combined with conventional therapy for patients with coronary heart disease(CHD). We searched 8 electronic databases up to November 2020, including PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, VIP and SinoMed. Eligible studies were clinical trials of Shexiang Tongxin Dropping Pills combined with conventional therapy used in the treatment of coronary heart disease(CHD). The Meta-analysis was performed using STATA 15 software. A total of 21 RCTs(n=2 186) were shortlisted for the Meta-analysis. The results of efficacy evaluation showed that the total effective rate of Shexiang Tongxin Dropping Pills combined with conventional therapy was higher than that of conventional therapy of coronary heart disease(RR=1.20, 95%CI[1.15, 1.26], Z=8.63, P<0.001). Furthermore, Shexiang Tongxin Dripping Pills combined with conventional therapy had better effect on electrocardiogram efficacy(RR=1.24, 95%CI[1.16, 1.34], Z=5.98, P<0.001) and the number of angina attacks(SMD=-2.30, 95%CI[-3.47,-1.14], Z=3.88, P<0.001), the duration of angina attack(SMD=-2.31, 95%CI[-3.07,-1.55], Z=5.97, P<0.001), with lower levels of LDL-C(SMD=-0.73, 95%CI[-1.32,-0.14], Z=2.42, P=0.016), TC(SMD=-1.16, 95%CI[-1.35,-0.96], Z=11.56, P<0.001) and TG(SMD=-0.87, 95%CI[-1.06,-0.68], Z=8.97, P<0.001), and higher levels of HDL-C(SMD=0.87, 95%CI[0.02, 1.71], Z=2.00, P=0.045). The results of safety evaluation showed that the incidence of adverse reactions of Shexiang Tongxin Dropping Pills combined with conventional therapy was lower than that of conventional therapy of coronary heart disease(RR=0.45, 95%CI[0.22, 0.91], Z=2.23, P=0.026). There were significant differences in the above outcome indexes between the two groups. After the Harbord method test, the total effective rate outcome index has publication bias, but the sensitivity analysis of the cut-and-fill method suggested that the result was stable. In general, limited by the quantity and quality of included literature, more high-quality studies are needed to further verify the conclusions of this study.

<p><b>OBJECTIVE</b>To analyze the genetic characteristics of two rabies virus isolates from Henan province and to compare their relations hip with known rabies virus isolates and vaccine strains.</p><p><b>METHODS</b>Rabies viral antigens were detected in 100 canine brains by immunofluorescence assay method. Rabies virus was isolated through inoculating the suspensions of positive brains into suckling mice. N gene and G were amplified by RT-PCR and sequenced. Phylogenetic trees were constructed for the analysis on genetic characteristics of rabies virus.</p><p><b>RESULTS</b>Two rabies virus strains were isolated (Henan Hb1 and Henan Sq1). Data from sequential comparison revealed that the nucleotide and amino acid identities of N and G gene between the two isolates were 99.3% and 98.9%, and 98.7% and 98.4% respectively. The two isolates were more closely related to CTN, with the homogeny of N gene and G gene as 89.1% and 85.6%-85.7% at the nucleotide level, but 97.6%-98.0% and 92.3% at the amino acid level respectively, than to other vaccine strains. When comparing with other known viruses including Chinese isolates, the two stains shared closer identity with the isolates from Indonesia, and the rates of homogeny of N and G gene were 92.1%-93.2% and 91.9%-92.1% at the nucleotide level, 97.5%-98.6% and 96.0%-96.2% at the amino acid level, respectively. Data from the deduced amino acid sequences revealed that some amino acid residues including the residues in the N and G antigenic sites were substituted in the two isolates. Furthermore, phylogenetic analysis showed that the two isolates were also more closely related to the strains from Indonesia and vaccine strain CTN than to any other known street viruses and vaccine strains.</p><p><b>CONCLUSION</b>Both Henan Hbl and Henan Sql belonged to genotype 1. However, the N and G gene diverged from known street viruses and vaccine strains at either nucleotide level or amino acid level.</p>

<p><b>OBJECTIVE</b>To establish genetic method in detecting Cryptosporidium parvum and Giardia lamblia which often coinfected with AIDS patients.</p><p><b>METHODS</b>Cryptosporidium oocysts and Giardia cysts were isolated and purified from fecal samples of the individuals infected with C. parvum and G. lamblia, respectively. Genomic DNAs were extracted. Two pairs of specific primers were designed or synthesized according to the 18S rRNA gene from C. parvum or the triose phosphate isomerase (tim ) gene from G. lamblia. Polymerase chain reaction(PCR) technique was used to amplify the DNA samples from the oocysts and the cysts, and those from the 6 control samples, including Schitosoma japonicum, Toxoplasma gondii , Entamoeba histolytica, Trichinella spiralis, Trichomonas vaginalis and human blood cells. DNA samples from 30 fecal samples of AIDS patients were detected with the same method.</p><p><b>RESULTS</b>One fragment of 500 bp was amplified with the primer of C. parvum, and the other one of 683 bp was amplified with the primer of G. lamblia. Twenty pg and 0.4 pg DNA of C. parvum and G. lamblia could be detected separately. The specificity of these two pairs of PCR primers was confirmed by the failure in the amplification of the control DNA samples. Out of 30 cases of AIDS patients, 7 showed C. parvum positive, while non Giardia was detected.</p><p><b>CONCLUSION</b>Genetic detection method for C. parvum and G. lamblia detection was established which was more sensitive and specific.</p>
