ObjectivesTo systematically review the perinatal outcomes after laparoscopic myomectomy versus transabdominal myomectomy.MethodsPubMed, Web of Science, Elsevier, The Cochrane Library, CNKI, VIP and WanFang Data databases were searched from inception to July 2017, to collect randomized controlled trials or cohort studies comparing the perinatal outcomes after laparoscopic myomectomy and transabdominal myomectomy. Two reviewers independently screened literature, extracted data and assessed the risk of bias of include studies. Meta-analysis was then performed by RevMan 5.3 software.ResultsEight randomized controlled trials, twenty-one cohort studies involving 4357 patients were included. The results of meta-analysis showed that: the premature birth rate (OR=0.60, 95%CI 0.38 to 0.95, P=0.03) in the laparoscopic myomectomy was lower than that in the laparotomy group. However, the rate of uterine rupture during pregnancy (OR=3.19, 95%CI 1.29 to 7.89, P=0.01) in the laparoscopic myomectomy was higher than that in the laparotomy group. There were no significant differences between two groups in the myoma residual (OR=1.00, 95%CI 0.37 to 2.65, P=0.99), recurrence (OR=0.92, 95%CI 0.68 to 1.25, P=0.60), abortion (OR=0.90, 95%CI 0.63 to 1.28, P=0.56), ectopic pregnancy (OR=1.11, 95%CI 0.54 to 2.26, P=0.78), pregnancy rate (OR=1.06, 95%CI 0.89 to 1.27, P=0.52), cesarean (OR=0.82, 95%CI 0.57 to 1.19, P=0.31), and pregnancy complications (OR=0.84, 95%CI 0.45 to 1.59, P=0.60).ConclusionsCurrent evidence shows that there are no significant differences between two groups in the myoma residual, myoma recurrence, abortion, ectopic pregnancy, pregnancy rate, cesarean and pregnancy complications. While the rate of uterine rupture during pregnancy in the laparoscopic myomectomy is higher than that in the laparotomy group, the premature birth rate after operation in the laparoscopic myomectomy is lower and shorter than that in the laparotomy group. Due to the limited quantity and quality of the included studies, more high quality studies are required to verify the above conclusion.
ObjectivesTo systematically review the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure in vitro fertilization.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect clinical controlled studies on the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure from inception to March 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.ResultsA total of 10 studies, including 8 randomized controlled trials and 2 case-control studies, and involving 1 274 patients were included. The results of meta-analysis showed that: the clinical pregnancy rate of endometrial mechanical stimulation group was higher than that of control group (RR=1.40, 95%CI 1.04 to 1.89, P=0.03). However, no significant differences were found in implantation rate (RR=0.75, 95%CI 0.50 to 1.13, P=0.17), live births rate (RR=1.38, 95%CI 0.99 to 1.93, P=0.06), miscarriage rate (RR=0.83, 95%CI 0.55 to 1.24, P=0.36) and rate of multiple pregnancy (RR=0.90, 95%CI 0.61 to 1.35, P=0.63).ConclusionCurrent evidence shows that, for patients with repeated implantation failure, mechanical endometrial stimulation before re-transplantation may help to improve the clinical pregnancy rate of test-tube infants, however, it has no significant effects on implantation rate, live birth rate, abortion rate, multiple pregnancy rate and ectopic pregnancy rate. Due to limited quality and quantity of the included studies, more high quality studies are needed required to verify above conclusions.
Objective To evaluate the efficacy and safety of trimetazidine (TMZ) in the treatment of Stable Angina Pectoris (SAP). Methods Randomized controlled trials (RCTs) on the efficacy and safety of Trimetazidine in treating patients with SAP were retrieved in the following databases as CNKI (1997 to June 2011), WanFang Data (1989 to June 2011), MEDLINE (1966 to June 2011), EMbase (1974 to June 2011), CBM (1989 to June 2011) and Cochrane Central Database (1989 to June 2011). The literature which met the inclusion and exclusion criteria were selected, data were extracted, the quality was evaluated, and meta-analysis was performed by using RevMan 5.0 software. Results A total of 15 RCTs involving 1 500 patients were included. The meta-analysis showed that, compared with the control group, TMZ was significantly superior in the following 5 aspects: the time to 1 mm drop of ST segment (WMD=0.84, 95%CI 0.74 to 0.93, P=0.000 01), duration of doing exercise (WMD=0.82, 95%CI 0.73 to 0.91, P=0.000 01), and time to onset of angina (WMD=1.18, 95%CI 0.87 to 1.50, Plt;0.000 01) in the treadmill test, weekly mean number of angina attacks (WMD= –1.79, 95%CI –1.93 to –1.66, Plt;0.000 01), and weekly side effects between TMZ and the control group (RR=0.83, 95%CI 0.52 to 1.32, P=0.42). Conclusion Based on current studies, TMZ is superior to other medicines in the control group for SAP at present, and it has no significant difference in side effects compared with the control group, so it is regarded as an effective and safe drug. For the quality restrictions and possible publication bias of the included studies, this conclusion needs to be confirmed by more high quality, large sample, multi-center, double blind RCTs.
ObjectivesTo systematically review the safety of harmonic scalpel and conventional resection in superficial parotidectomy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) or cohort studies of harmonic scalpel and conventional resection in superficial parotidectomy from the inception of the database to December, 2018. Two reviewers independently screened literatures, extracted data and assessed risk of bias of the included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 studies involving 671 post-cesarean section patients (361 patients in harmonic scalpel group and 310 patients in conventional resection group) were included. The results of meta-analysis showed that: compared with conventional resection, harmonic scalpel had shorter operative time (MD=?23.82, 95%CI ?31.20 to ?16.44, P<0.000 01), less postoperative drain output (MD=?26.25, 95%CI ?38.95 to ?13.55, P<0.000 1), less intraoperative blood loss (MD=?23.78, 95%CI ?28.64 to ?18.91, P<0.000 01), shorter duration of hospital stay (MD=?1.19, 95%CI ?2.14 to ?0.23, P=0.02), and lower temporary facial nerve palsy rate (OR=0.27, 95%CI 0.14 to 0.50, P<0.000 1). However, there was no significant difference in the incidence of parotid gland leakage between two groups (OR=0.42, 95%CI 0.16 to 1.06, P=0.07).ConclusionsThe current evidence demonstrates that, compared to conventional resection, harmonic scalpel resection is safer. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
ObjectiveTo systematically review the clinical efficacy of low molecular weight heparin (LMWH) in treating patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).
MethodsDatabases including PubMed, The Cochrane Library (Issue 10, 2013), EMbase, CBM, CNKI, VIP and WanFang Data were searched for the randomized controlled trials (RCTs) about LMWH in treating acute exacerbation of COPD from the establishment to October 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality of the included studies. Meta-analysis was then performed using RevMan 5.2 software.
ResultsA total of 6 RCTs involving 501 patients were finally included. The results of meta-analysis showed that:compared with the control group, LMWH significantly improved levels of D-dimmer (MD=-0.28, 95%CI-0.50 to-0.05, P=0.02), reduced carbon dioxide partial pressure (PaCO2) (MD=-3.42, 95%CI-6.66 to-0.18, P=0.04), improved coagulation (PT) (MD=1.85, 95%CI 1.29 to 2.42, P < 0.000 01), and improved clinical symptoms and signs (RR=1.33, 95%CI 1.12 to 1.58, P=0.001), but it did not improve oxygen partial pressure (PaO2) (MD=0.28, 95%CI-3.04 to 3.61, P=0.87). During treatment, no severe adverse reaction occurred in both groups.
ConclusionLMWH could significantly improve symptoms caused by acute exacerbation of COPD. Due to limited quantity and quality of the included studies, the above conclusion needs to be confirmed by conducting more high quality RCTs with larger sample size.
ObjectiveTo systematically review the influence on ovarian reserve function by different hemostatic methods during laparoscopic cystectomy in treatment of ovarian endometrioma (OE).
MethodsDatabases including The Cochrane Library, PubMed, EMbase, CNKI, CBM and WanFang Data were electronically searched, to collect relevant randomized controlled trials (RCTs) about laparoscopic electro coagulation vs. microscopically suture for OE from 1990 to Mar, 2014. Meanwhile, references of included studies were also retrieved manually. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the risk of bias of included studies. Then RevMan 5.2 software was used for meta-analysis.
ResultsA total of 16 RCTs involving 1 236 patients were finally included. The results of meta-analysis showed that the luteinizing hormone (LH) levels after 1 month, 2 months, 6 months and 12 months and estradiol (E2) levels after 2 months, 6 months had no significant differences between the two groups and the E2 level after 12 month of the suture group was significantly lower than that of the electro coagulation group. The levels of follicle stimulating hormone (FSH), LH, E2, antral follicle count (AFC), mean ovarian stromal peak systolic blood flow velocity (PSV) and anti-Mullerian hormone (AMH) in the suture group were significantly superior to those in the electro coagulation group at other follow-up time.
ConclusionCurrent evidence suggests that in treatment of ovarian endometriotic cyst by laparoscopic cystectomy, compared with electro coagulation hemostasis, suture hemostasis has less influence on ovarian reserve function. Due to limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
Objective To investigate the quality of the randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) integrated with western medicine for severe acute respiratory syndrome (SARS). Method All the randomized controlled trials of traditional Chinese medicine integrated with western medicine for SARS worldwide were gained by electronic searching and hand searching. The quality of the RCTs was analyzed by the quality grade evaluation used in Cochrane handbook.The sample size, the baseline data, the results indexes were also analyzed. Results Seven RCTs included 501 SARS cases were identified. The quality grade of one RCT is B, the other six RCTs were graded C. None pre-specified sample size. One RCT tested the differences of the baseline data by statistic method. One RCT reported quality of life as result index. None reported the adverse events.Conclusions Current RCTs of TCM integrated with western medicine can’t provide b evidence for clinical practice because of the poor quality.
Objective
To investigate the efficacy and safety of ultrasound-guided TAP block for the anesthesia in peritoneal dialysis (PD) catheter implantation.
Methods
Patients with end-stage renal disease who intended to receive PD catheter implantation in the West China Hospital of Sichuan University were enrolled from April 2015 to February 2016. Those who met the inclusion criteria were randomly divided into two groups: the local filtration anesthesia (LF) group and the TAP group. The two groups got the ultrasound guided TAP block (The LF group got a shame TAP block by making the skin wheal and just inserting the needle into the TAP with the guidance of ultrasound), then the LF group received local filtration anesthesia twenty minutes later, with the TAP group had sham LF anesthesia by injection of saline at the incision subcutaneously. The anesthetist generated the random allocation sequence and performed all TAP/sham blocks according to the allocation of each patient. The patients, investigators were all blind to the allocation. The follow-up time was 3 months. The primary outcomes were the rate of alteration to general anesthesia and the VAS score during and after the surgery. The dosages of sufentanil for analgesia during and after were recorded. The satisfaction to the effect anesthesia by the operation doctors, PD catheter related complications and adverse events related to TAP block or anesthetic agent were also recorded. Statistic analysis was conducted using SPSS 19.0 software.
Results
A total of 36 patients were included, 12 cases in the LF group and 24 cases in the TAP group. The rate of alteration to general anesthesia in the TAP group was 4.12% and was significantly lower than that in the LF group (33.3%) (P=0.034). The VAS scores at the time points of incision of skin, division of subcutaneous tissue and anterior rectus sheath, opening the peritoneum, insertion of PDC, suture of skin, 2 hours and 24 hours after operation were significantly lower in the TAP group compared to the LF group (P values=0.001, 0.037, 0.000, 0.001, 0.029, 0.035, and 0.000, respectively). The TAP group consumed less sufentanil during the operation and showed a higher satisfaction of the operation doctors. There were no significant differences in the PD catheter related complications and adverse events between the two groups.
Conclusion
The ultrasound-guided TAP block can be an effective and safe anesthesia method for PD catheter implantation. Because of the limitation of small sample size of this study, a multiple center study with larger sample size is suggested.
Objective To evaluate the effectiveness of GnRH antagonist on vitro fertilization-embryo transfer (IVF-ET). Methods We searched CBMdisc (1979 to 2010), Wanfang (1994 to 2010), CNKI (1994 to 2010), VIP (1989 to 2010), PubMed (1997 to 2010), PML (1997 to 2010), FMJS (2000-2010), and 9 related journals to identify randomized controlled trials (RCTs) on the comparison between GnRH antagonist (GnRHA) and GnRH agonist (GnRHa). The quality of included trials was critically appraised. RevMan 4.2.7 software was used for statistical analysis. Results Six published RCTs involving 1 208 participants were included. Compared with the GnRHa group, stimulation duration in the GnRHA group was lower (WMD= –1.07, 95%CI –1.38 to –0.76), dose of gonadotrophins (Gns) in the GnRHA group was slightly lower (WMD= –0.49, 95%CI –1.63 to 0.66), endometrial thickness at the time of HCG administration was no significant difference in the two groups (WMD= –0.09, 95%CI –0.42 to 0.24), number of oocytes retrieved in the GnRHA group was lower (WMD= –1.80, 95%CI –2.48 to –1.12), OHSS rate in the GnRHA group was slightly lower (Peto OR= 0.77, 95%CI 0.35 to 1.72), pregnancy rate in the GnRHA group was slightly lower (Peto OR= 0.83, 95%CI 0.65 to 1.05), miscarraige rate as no significant difference in the two groups (Peto OR= 1.49, 95%CI 0.79 to 2.82). Conclusions Compared with GnRHa, GnRHA requires shorter stimulation duration and less Gn, less affected the pregnancy rate, and reduces the incidence of OHSS. The use of GnRHA in clinical practice is relatively flexible with good acceptability. GnRHA for the superovulation IVF-ET offers an alternative treatment. The above conclusion still needs more well-designed, multi-center, and large-scale RCTs to confirm and update.
Objective To evaluate the effectiveness of intravenous patient-controlled analgesia versus epidural patient-controlled analgesia for postoperative analgesia, sedation, and the incidence of side effects. Methods We searched the specialized trials registered in the Cochrane anesthesia group, The Cochrane Library (CCTR), MEDLINE (1966 to Sept. 2008), EMbase (1966 to Sept. 2008), PubMed (1966 to Sept. 2008), and handsearched some Chinese anesthesia Journals and Clinical anesthesia journals. Randomized controlled trials (RCTs) and quasi-RCTs of intravenous versus epidural analgesia for post-operation were included. The quality of the trials was critically assessed. RevMan 4.2.8 software was used for meta-analyses. Results Thirteen RCTs involving 580 patients of intravenous versus epidural analgesia for post-operation were included. The results of meta-analyses showed that there were no significant differences in postoperative analgesia and sedation at the hour-points of 2nd, 4th, 8th, 12th, and 24th hours after operation. There were no significant differences in plasma fentanyl concentration in the two groups on the same analgesia effects. There were also no significant differences in side effects. Conclusion Both intravenous patient-controlled analgesia and epidural patient-controlled analgesia have the same clinical effects. Compared with epidural patient-controlled analgesia, intravenous patient-controlled analgesia has fewer side effects and is more convenient. At the same time, it can reduce more costs of hospitalization. But because of the low quality and small sample size of the included studies, more well-designed, large scale, randomized controlled trials are needed.
