Perineal care is a classic topic for obstetrics. After thousands of years of practice, we have accumulated some experience and meanwhile, we are also taking some attempts. The effectiveness and reliability of these methods need evaluation. Nowadays, the best evidence comes from randomized controlled trials (RCT) and systematic reviews (SR). We searched The Cochrane Library (Issue 3, 2007), MEDLINE (Jan. 1980 to May 2007) databases and CBM-disc (Jan. 1980 to May 2007) to obtain current best evidence for perineal care.
Objective To compare the efficacy and incidence of complications between laparoscopic surgery and laparotomy on women with polycystic ovarian syndrome (PCOS). Methods We did a systematic literature search for studies from Ovid Database, MEDLINE, EMbase, Cochrane Library (Issue 2, 2008), Chinese Biological Medicine Database, CNKI, Chinese VIP Database, and WANFANG Database on internet. The search time was from establishment of each database to December, 2008. Randomized controlled trials and non-randomized controlled trials were collected. The search was no limitation in language. We manually searched current and conference abstracts, and searched relevant reviews and their reference. RevMan 5.0 software was used for meta-analysis. Results Five non-randomized trials involving 417 patients were included. The results of meta-analyse showed that the short-term pregnancy rate in patients underwent laparoscopic surgery was significantly higher than that in patients underwent laparotomy (RR=1.42, 95% CI 1.13 to 1.80, P=0.003). The long-term pregnancy rate in patients underwent laparoscopic surgery and laparotomy was comparable (RR=0.85, 95%CI 0.68 to 1.07, P=0.17). The regular menstruation in patients underwent laparoscopic surgery and laparotomy was comparable (RR=0.91, 95%CI 0.79 to 1.05, P=0.18). The uterine adhesions in patients underwent laparoscopic surgery was significantly lower than that in patients underwent laparotomy (RR=0.02, 95%CI 0.00 to 0.18, P=0.000 2). The intra-abdominal adhesions of patients underwent laparoscopic surgery was significantly lower than that in patients underwent laparotomy (RR=0.02, 95%CI 0.00 to 0.13, Plt;0.000 1).Conclusions The limited evidence at present shows that the incidence and degree of pelvic adhesions occurred in patients with PCOS after laparoscopic surgery is much lower than those after laparotomy. It is not quite sure at this point about whether the pregnancy rate and regular menstruation of laparoscopic surgery are better than those of lararotomy or not. More evidence from high qualified multi-center studies is needed.
With clinical medicine science transforming from traditional medicine to evidence-based medicine, how to practice evidence-based medicine has become a new challenge to clinical doctors. Therapy studies play an important part in clinical studies and how to practice evidence-based medicine in the therapy of diseases is an important question that doctors are concerned. This paper will introduce as on how to practice evidence-based medicine in the therapy of diseases.
Researches in evidence-based medicine have provided important evidence for family planning doctors to guide their clinical practice. With examples of clinical researches, the practical methods of evidence-based medicine in family planning service are discussed in this paper.
Objective To assess the effectiveness and safety of traditional Chinese medicinal herbs for subfertility. Method Databases used including MEDLINE, EMBASE, CBM and the Cochrane Controlled Trial Register (CCTR). Potentially related trials in reference lists of studies were hand searched. Published RCTs in any languages and length whether they were blind or unblind, were included. Treatments were Chinese medicinal herbs (single or compound), and controls were placebo, standard medical intervention, or no intervention. Data were extracted independently by two reviewers and analyzed with Revman 4.2 softeware. Results 7 randomized trials, including 1 042 patients met inclusion criteria. Methodological quality of all trials was poor. Chinese medicinal herbs were effective compared with routine antibiotics [RR 1.49, 95％CI (1.37 to1.62), Plt;0.000 01] and resulted in higher pregnancy rate [RR 1.46, 95%CI (1.09 to,1.96), P=0.01]. There were no adverse events reported in treatment group. Conclusions Some Chinese medicinal herbs may be effective for subfertility. However, the evidence is too weak to draw a conclusion. More strictly designed, randomized, double-blind, placebo-controlled trials are required.
Objective To assess the effectiveness and safety of Chinese medicinal herbs for female immune-caused subfertility. Methods Databases included: MEDLINE (1966-2002.2), EMBASE (1984-2002.2), CBM (1978-2002.2) and Cochrane Controlled Trial Register, CCTR (Issue 1, 2002). Reference lists of trials were handsearched. Published randomized controlled trials (RCTs) whether blind or unblind, any languages and length of follow up were included. Treatments included Chinese medicinal herbs (single or compound). Controls were placebo and western medicine, or no intervention. Data were extracted independently by two reviewers and analyzed with Revman 4.2. Results Six RCTs were included, all of which were poor in methodological quality. Because of different therapies in the treatment and control groups, we did not perform meta-analysis. The No.1 anti-immune tablet was more effective than corticosteroid plus condom during intercourse both in the pregnancy rate (RR 3.75, 95%CI 1.61 to 8.75, P=0.002) and AsAb negative rate (RR 1.66, 95%CI 1.23 to 2.22, P=0.000 8). Bushen Xiezhuo Soup was more effective than antibiotic in the pregnancy rate (RR 2.97, 95%CI 1.60 to 5.50, P=0.000 6) and antisperm antibody (AsAb) negative rate (RR 2.33, 95%CI 1.54 to 3.54, Plt;0.000 1)。Zhenqi Zhuanyin Soup was as effective as IUI in pregnancy rate (RR 1.80, 95%CI 0.58 to 5.60, P＝0.31) but more effective than IUI in AsAb negative conversion rate (RR 9.61, 95%CI 3.22 to 28.67, Plt;0.000 1), Zhenqi Zhuanyin Soup combined with IUI was more effective than IUI in pregnancy rate (RR 3.60, 95%CI 1.32 to 9.85,P=0.01) and AsAb negative rate (RR 8.92, 95%CI 2.98 to 26.75, Plt;0.000 1). Conclusions Some Chinese medicinal herbs may work well in subfertility treatment. However, the evidence is too weak to draw a conclusion for there are deficiencies in strict randomization, blinding and follow-up.More strictly designed, randomized, double-blind, placebo-controlled trials are required.
ObjectivesTo systematically review the efficacy and safety of traditional Chinese herbal medicine Kuntai in the treatment of premature ovarian insufficiency (POI).MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on Kuntai for treating premature ovarian insufficiency from inception to August, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsTwenty-one RCTs involving 1 777 patients were included, which were categorized as Kuntai vs. western medicine and Kuntai combined with western medicine vs. western medicine. The results of meta-analysis showed that: the efficacy of Kuntai was equivalent to western medicine; effective rate (RR=2.78, 95%CI 1.73 to 4.45, P<0.000 01), the change of Kupperman’s score (MD=−3.25, 95%CI −3.75 to −2.76, P<0.000 01), the change of serum FSH (MD=−6.99, 95%CI −8.07 to −5.90, P<0.000 01), E2 (MD=7.01, 95%CI 3.01 to 11.01, P=0.000 6) and LH (MD=−4.66, 95%CI −6.45 to −2.86, P<0.000 01) in Kuntai combined with hormone replacement therapy (HRT) group were higher than that in the HRT group.ConclusionsKuntai combined with HRT is superior to HRT alone in the effective rate, the change of Kupperman’s score, the change of serum FSH, E2 and LH for patients with premature ovarian insufficiency. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusion.
Objective To provide evidence for establ ishing a health care system for pregnant women after disasters by evidence-based evaluation on the comparison of programs in different countries of the world. Methods We electronically searched The Cochrane Library (Issue 2, 2008), MEDLINE (1966 to June 2008), EMbase (1984 to June 2008), VIP ( 1989 to June 2008), CBM ( 1978 to June 2008), Wangfang database (1997 to June 2008), CNKI (1994 to June 2008) and handsearched Journals such as Chinese Journal of Obstetrics and Gynecology to identify l iteratures and guidel ines on pregnant women healthy care system after calamity. The qual ity of l iteratures and guidel ines was assessed. Results A total of 293 studies were searched, of which 25 studies were identified with the focuses on the consequence of pregnancy, development of fetus and first-aid of injuries of pregnant women. We found the studies on pregnant women’s health care were l imited, and most of them were retrospective and cohort studies, which was related to the paroxysmal ity, rarity and complexity of the disaster.? Conclusions The high proportion of pregnant women among displaced persons underscores the importance of examining how behavioral changes and difficulties in access to health care influencing the maternal and infant health, which needs comprehensive planning and arrangement.
Objective To compare and evaluate the sensitivity, specificity, accuracy, negative and positive predictive values, negative and positive likelihood ratios of colposcopically directed biopsy and diagnostic cone biopsy in patients with cervical intraepithelial neoplasia. Methods We searched PubMed, CBMdisc, CMCC, CNKI, and VIP to March 2004, and Cochrane Library (Issue 4, 2003). Related journals published from 1970 to 2003 and unpublished papers were hansearched. Diagnostic studies which employed colposcopically directed biopsy or diagnostic cone biopsy and compared with golden standard (pathological diagnosis of specimens obtained through therapeutic conization or hysterectomy) were included and meta-analysis was performed. Participants were clinically suspected of pre-cancerous cervical lesions. Quality of studies was assessed, and SROC curve by Diagnostic and Screening Group of the Cochrane Collaboration was used to perform meta-analysis. Parameters were sensitivity, specificity, accuracy, predictive values, and likelihood ratio. Results Twenty six studies (3 376 patients ranging from 2 to 604 patients/per study) met the inclusion criteria. The quality of studies was generally poor.Before sensitivity analysis, superiority of diagnostic cone biopsy (sensitivity and specificity: 0.83) was shown over colposcopically directed biopsy (sensitivity and specificity: 0.76) (P＜0.001); while after sensitivity analysis the results reversed (sensitivity of diagnostic cone biopsy was 0.58 and its specificity was 0.61; sensitivity and specificity of colposcopically directed biopsy increased to 0.84) (Plt;0.001). Conclusions No definite conclusioncan be drawn as to which method is superior. To make further analysis, more studies with high quality are needed.
Abnormal uterine bleeding with ovulatory dysfunction (AUB-O) is a common reproductive endocrine disease with complex and variable clinical manifestations. This disease has a long course and large individual differences. Difficulties in diagnosis and treatment and nonstandardized management are common in primary hospitals. In order to improve the diagnosis and treatment efficiency of AUB-O in primary hospitals, the gynecological endocrinologists in western China proposed this primary diagnosis and treatment norms and referral recommendations for gynecological outpatient clinics in primary hospitals, including the key points of diagnosis, hemostasis and cycle adjustment strategies, adjuvant treatment, and the principle of two-way referral. In particular, individualized treatment recommendations were proposed for young adolescents and menopausal transition patients. This recommendations are expected to serve as an important reference for AUB-O diagnosis, treatment and two-way referral of primary hospitals in western China.
