Systematic review and Meta-analysis of efficacy and safety of Kushen Gelatum combined with antibiotics in treatment of bacterial vaginosis / 中国中药杂志

This study aims to systematically evaluate the clinical efficacy and safety of Kushen Gelatum combined with antibiotics for treating bacterial vaginosis. The randomized controlled trial(RCT) of Kushen Gelatum for treating bacterial vaginosis were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, and Cochrane Library with the time interval from inception to January 2023. Data were extracted from the included RCT by 2 investigators, including the sample size, characteristics of patients, interventions and controls, outcome indicators, and adverse effects. The Cochrane collaboration network's bias risk assessment tool was used for methodolo-gical quality evaluation of the included trials. RevMan 5.4 was employed to perform the Meta-analysis. A total of 19 RCTs were inclu-ded, involving 1 980 patients with bacterial vaginosis. Meta-analysis showed that, compared with nitroimidazoles alone, Kushen Gelatum + nitroimidazoles improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.24, 95%CI[1.13, 1.36], P<0.000 01), laboratory tests(RR=1.16, 95%CI[1.06, 1.26], P=0.000 9), and clinical symptoms(RR=1.26, 95%CI[1.08, 1.46], P=0.003), and reduced the leukocyte esterase positive rate(RR=0.29, 95%CI[0.17, 0.48], P<0.000 01) and the recurrence rate(RR=0.37, 95%CI[0.23, 0.58], P<0.000 1). Compared with lincomycin antibiotics(clindamycin) alone, Kushen Gelatum + lincomycin antibiotics(clindamycin) improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.06, 1.31], P=0.003) and laboratory tests(RR=1.27, 95%CI[1.04, 1.54], P=0.02), reduced the recurrence rate(RR=0.20, 95%CI[0.05, 0.75], P=0.02), and shortened the time to relief of burning sensation(MD=-1.70, 95%CI[-2.15,-1.26], P<0.000 01), vaginal itching(MD=-0.82, 95%CI[-1.30,-0.34], P=0.000 8), and abnormal leucorrhea(MD=-1.52, 95%CI[-1.98,-1.06], P<0.000 01). Compared with nitroimidazoles + probiotics, Kushen Gelatum + nitroimidazoles + probiotics improved the total response rate in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.02, 1.36], P=0.03) and reduced the recurrence rate(RR=0.27, 95%CI[0.09, 0.76], P=0.01). Kushen Gelatum combined with antibiotics demonstrates a potential therapeutic effect on bacterial vaginosis, whereas the number and quality of the relevant clinical studies remain to be improved. The process of clinical trial should be standardized to improve the quality of evidence, so as to provide strong evidence to guide the application of Kushen Gelatum in clinical practice.

Investigation on skills of using dust mask in dust-exposed workers of civil metal ship manufacturing enterprises / 中国职业医学

OBJECTIVE: To analyze the skills of using dust mask in the dust-exposed workers in civil metal ship manufacturing enterprises. METHODS: A total of 123 dust-exposed workers in a civil metal ship manufacturing enterprise were selected as the research subjects using convenience sampling method. Dust Mask Using Situation and Maintenance Questionnaire was used to investigate the use of dust masks, and the tightness of using dust mask was measured by the tightness tester. RESULTS: The median, and the 0 th-100 th percentiles[M(P_0-P_(100))] of the dust mask use time in the workers was 3.0(1.0-3.0) months, and the M(P_0-P_(100)) of filter element use time was 1.0(0.5-2.0) workdays. The subjects did not disinfect the masks after use. Only 36.6%(45/123) of workers regularly cleaned dust masks during use. There was 62.6%(77/123) of workers who failed to correctly perform negative pressure air tightness check by themselves. A total of 112 workers carried out tightness test, and the pass rate of those who passed the tightness test for the first time was 62.5%(70/112). The median, and the 25 th and 75 th percentiles [M(P_(25), P_(75))] of fit factor(FF) in the 70 qualified workers was 835.0(503.0, 1 635.0). After retests, the overall tightness test pass rate was 66.1%(74/112), and the M(P_(25), P_(75)) of FF in the 74 qualified workers was 786.0(477.7, 1 532.2). The reasons for failure of tightness test were the mismatch of the mask and face size, wrong wearing methods and long beard. CONCLUSION: Some of the dust-exposed workers in the civil metal ship manufacturing enterprises did not use the dust mask correctly. The dust mask configuration and the use and maintenance training should be strengthened, and the tightness test should be carried out regularly to improve workers′ skills in using dust masks.

OBJECTIVE: To explore the distribution characteristics of single nucleotide polymorphism(SNP) rs7072793 and rs3118470 in the 5′ flanking region of(cluster of differentiation 25, CD25) gene in Han males in the naturally high radiation background area(HBRA). METHODS: A random sampling method was used to select 48 and 51 healthy Han males from Tangkou town(HBRA group) in Yangjiang City and Hengpo town(control group) in Enping City, respectively, as the study subjects. The molecular mass array method was used to classify the genotype of the SNP sites rs7072793 and rs3118470 of CD25 gene in these subjects. The distribution difference of the alleles and genotypes was analyzed in individuals of these two groups. The allele frequency of HBRA population was compared with the distribution data of different populations in the Human Genome Project.RESULTS: The distribution of allele frequencies of rs7072793 and rs3118470 in both groups were consistent with the H-W equilibrium law of genetics(all P>0.05). In the HBRA group, variant allele C(58.3%) and genotype TC(50.0%) were dominant at rs7072793, wild-type allele T(55.2%) and genotype TC(56.2%) were dominant at rs3118470. There was no significant difference in the allele and genotype distributions between these two groups(all P>0.05). There was a difference of rs7072793 in the HBRA group compared to that of African and European populations, and rs3118470 in the HBRA group compared with the allele distribution frequencies in Africa, Europe and America populations(all P<0.05). CONCLUSION: In the male population of Han nationality in Yangjiang HBRA area, the alleles of rs7072793 and rs3118470 in the 5′ flanking region of CD25 gene were mainly C and T, respectively, and the genotypes were mainly TC. These two loci may have high genetic variability.

Role of Laparoscopy in Management of Ectopic Pregnancy.

Ectopic pregnancy means implantation of fertilized ovum outside the endometrial lining of the uterus. It remains the leading cause of early pregnancy-related death. Delay in diagnosis and treatment puts the life of women at risk. Laparoscopic surgery is increasingly becoming the preferred approach for ectopic pregnancy management. Laparoscopic treatment in ectopic pregnancy raises question of safety and feasibility when compared to laparotomy. In this review article our objective is to summarize the role of laparoscopy in management of ectopic pregnancy in comparison to laparotomy. For this, a literature search was done by using Google and PubMed. The selected articles were analyzed on laparoscopic treatment outcomes such as surgery success rate, operating time, intraoperative and postoperative complications, hospital stay, future fertility, postoperative recurrent ectopic pregnancy, cost-effectiveness in comparison to laparotomy. After analyzing all selected articles, it can be concluded that the laparoscopic management of ectopic pregnancy is safe, effective, and economical in comparision to laparotomy. So, for the patients’􀀀 benefit, laparoscopy should be considered as the gold standard method in management of ectopic pregnancy and is worthy to be popularized in clinical practice
