ObjectiveTo systematically review the efficacy and safety of Heluo Shugan capsule in the treatment of hepatitis B fibrosis.
MethodWe searched PubMed, The Cochrane Library (Issue 8, 2015), CBM, CNKI, VIP and WanFang Data from their inception to August 2015, to collect randomized controlled trials (RCTs) on Heluo Shugan capsule for hepatitis B fibrosis. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software.
ResultsA total of 15 RCTs involving 1 840 patients were included. The results of meta-analysis showed that: (1) As for reduced level of serum hyaluronic acid (HA), Heluo Shugan capsule was superior to placebo (MD=82.31, 95%CI 37.44 to 127.19, P=0.000 3), but worse than Fuzheng Huayu capsule (MD=-137.45, 95% CI-196.29 to-78.62, P < 0.000 01), Fufang Biejia Ruangan tablet (MD=-51.19, 95% CI-67.58 to-34.81, P < 0.000 01) and Anti-fibrosis decoction (MD=-82.13, 95% CI-102.37 to-61.88, P < 0.000 01). (2) As for reduced level of serum laminin (LN), Heluo Shugan capsule was superior to placebo (MD=36.83, 95% CI 11.84 to 61.82, P=0.004), but worse than Fufang Biejia Ruangan tablet (MD=-36.00, 95% CI-64.29 to-7.71, P=0.01), Ganfujian capsule (MD=-22.14, 95% CI-37.28 to-7.00, P=0.004) and Anti-fibrosis decoction (MD=-38.64, 95% CI-75.00 to-2.29, P=0.04). (3) As for reduced level of serum procollagen type III peptide (PCIII), Heluo Shugan capsule was superior to placebo (MD=47.17, 95% CI 32.68 to 61.66, P < 0.000 01), but worse than Fuzheng Huayu capsule (MD=-4.80, 95% CI-9.08 to-0.51, P=0.03), Dahuang Zhechong pills (MD=-53.77, 95% CI-105.01 to-2.53, P=0.04), Ganfujian capsule (MD=-46.82, 95% CI-66.30 to-27.34, P < 0.000 01) and Anti-fibrosis decoction (MD=-28.68, 95% CI-55.59 to-1.77, P=0.04). (4) As for reduced level of serum type-IV-collagen (IV-C), Heluo Shugan capsule was superior to placebo (MD=72.77, 95% CI 47.65 to 97.89, P < 0.000 01), but worse than Fuzheng Huayu capsule (MD=-34.69, 95% CI-56.65 to-12.73, P=0.002), Dahuang Zhechong pills (MD=-21.26, 95%CI-38.79 to-3.73, P=0.02), Fufang Biejia Ruangan tablet (MD=-69.04, 95%CI-124.38 to-13.69, P=0.01), Ganfujian capsule (MD=-19.84, 95% CI-37.41 to-2.27, P=0.03) and Anti-fibrosis decoction (MD=-37.98, 95% CI-72.99 to-2.96, P=0.03).
ConclusionCurrent evidence shows that, Heluo Shugan capsule was superior to placebo, but worse than Fufang Biejia Ruangan tablet, Fuzheng Huayu capsule, Dahuang Zhechong pills, Ganfujian capsule and Anti-fibrosis decoction in reducing the level of serum hepatic fibrosis. Due to the limited quantity and quality of included studies, more high-quality, large-scale RCTs are need to verify the above conclusion.
Objective To systematically review the effect of different nutrient interventions on the physical function of elderly people with frailty through network meta-analysis. Methods The PubMed, Cochrane Library, EMbase and Web of Science were electronically searched to collect randomized controlled trials of different nutrient interventions on physical function of the elderly with frailty, from database inception to June 30, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network meta-analysis was then performed using ADDIS 1.16.8, GeMTC 14.3, and Stata 15.0 software. Results A total of 13 studies involving 1 144 patients were included. There was no statistically significant difference in handgrip strength, time up to go test, gait speed, and short physical performance battery (SPPB) among different nutrient interventions. Significant differences were not found in vitamin D+ whey protein (VDWP) vs. placebo and Leu vs. placebo in handgrip strength, or VDWP vs. placebo in SPPB. The probability ranking diagram showed that the most effective of handgrip strength, time up to go test, gait speed, and SPPB were milk protein concentrate (MPC80), L-carnitime (L-Car), leucine (Leu), and MPC80, respectively. Conclusion The current evidence suggests that nutritional intervention did not significantly improve physical function in the frail elderly. MPC80, Leu, L-Car, and VDVEWP may play a role in improving the physical function of frail elderly people. Nutritional support programs that increase the above nutrients, combined with exercise training may become a better way to improve the physical function of frail elderly.
ObjectiveTo systematically review the association between 5α-reductase inhibitors (5ARIs) and risk of sexual dysfunction in subjects with benign prostatic hyperplasia (BPH).MethodsPubMed, Web of Science, The Cochrane Library, EMbase, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect studies on the association between 5ARIs and risk of sexual dysfunction in subjects with BPH from inception to October 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed by using Stata 12.0 software.ResultsA total of 15 studies involving 17 774 subjects were included. The results of the meta-analysis showed that compared with the placebo group, 5ARIs could significantly increase risk of erectile dysfunction (RR=1.52, 95%CI 1.36 to 1.69, P<0.000 1), while decrease libido (RR=1.79, 95%CI 1.37 to 2.32, P<0.000 1) and ejaculation disorder (RR=2.97, 95%CI 1.82 to 4.83, P<0.000 1) in subjects with BPH. Subgroup analysis of the type of 5ARIs, intervention period, publication year and sample size showed that the 5ARIs had a higher risk of sexual dysfunction than the placebo group.ConclusionsCurrent evidence shows that 5ARIs can increase risk of erectile dysfunction, decrease libido and ejaculation disorder in subjects with BPH. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
Objective To determine the efficacy and complication rate of intramedullary nailing versus compression plate in the treatment of adult humeral shaft fracture. Methods We searched the specialized trials register of The Cochrane Collaboration’s Bone, Joint and Muscle Trauma Group, The Cochrane Library (including CENTRAL), MEDLINE (1966 to 2006), EMbase (1980 to 2006), PubMed (1966 to 2006), NRR , CCT and CBMdisc (1979 to July 2006). We also handsearched some Chinese orthopedic journals. Data were extracted and evaluated by two reviewers independently. Randomize controlled trials comparing intramedullary nailing versus compression plate for humeral shaft fracture in adults were included and the quality of these trials was critically assessed. Data analyses were done using The Cochrane Collaboration’s RevMan 4.2.8. Results Three randomize controlled trials involving 215 patients were included. The meta-analysis showed that intramedullary nailing may increase the re-operation rate (OR=2.68, 95%CI 1.19 to 6.04, P=0.02), pain in the shoulder (OR=13.02, 95%CI 2.23 to 75.95, P=0.004), and the rate of decreased range of motion of the shoulder (OR=18.60, 95%CI 1.01 to 341.83, P=0.05). The rates of no union, infection and iatrogenic radial nerve injury were comparable between intramedullary nailing and compression plate. Meta-analysis was not conducted for the time of union, because the relevant data were not available for the included trials. Conclusions Further well-designed and large-scale randomize controlled trials are required to determine the effects of intramedullary nailing and compression plate on these outcomes, because the trials available for this systematic review are too few and too small.
Objective To assess the effect of atraumatic restorative treatment (ART) on decayed deciduous and permanent teeth in children. Methods Such databases as CENTRAL of The Cochrane Library, MEDLINE, EMbase, CBM, CNKI, and VIP were searched, and the China clinical trial register center were also searched. The search was conducted by the end of April, 2009 to collect the randomized controlled trials (RCTs) of ART vs. conventional restorative treatment (CRT) for childhood caries. The data extraction was performed by two reviewers independently. The quality of the included studies was critically assessed and the data analyses were performed by the Cochrane Collaboration’s RevMan 5.0.2 software. Results A total of seven randomized controlled trials were included. Only was the descriptive analysis conducted because of the difference of restorative materials used in each study, the types of target teeth, the measure indexes, and the year limit of follow up, which showed that, most of the included studies suggested that the survival rate of restorative materials in all types of caries hole was similar between the ART group and the CRT group; only a few studies suggested that the CRT group was superior to the ART group; the children in the ART group felt more comfortable than those in the CRT group during the treatment procedure; two studies compared the working time and got an opposite results. Conclusion Because of the higher clinical heterogeneity of the include studies, the merger analysis fails to be conducted, so it is impossible to get a precise conclusion about the effect of treating childhood caries with ART vs. CRT, and more RCTs with high quality are needed for confirmation.
ObjectiveTo evaluate the efficacy and safety of piolitazone combined with metformin for type 2 diabetes mellitus.
MethodsThe Cochrane Library (Issue 9, 2015), PubMed, EMbase, CNKI, WanFang Data and VIP databases were searched up to September 2015 for randomized controlled trials (RCTs) about pioglitazone combined with metformin versus sulfonylurea combined with metformin for type 2 diabetes mellitus. Two reviewers independently screened literature, extracted date, and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.
ResultsA total of 7 RCTs involving 3 005 patients were included. The results of metaanalysis showed that when the course of treatment was ≤24 weeks, no significant difference was found in the level of HbA1c between the piolitazone plus metformin group and the sulphonylurea plus metformin group (MD=-0.04, 95%CI -0.26 to 0.19, P=0.74), but the piolitazone plus metformin group had lower risk of hypoglycemia (RR=0.39, 95%CI 0.15 to 1.01, P=0.05); when the course of treatment >24 weeks, only one RCT was included, we didn't conduct pool analysis.
ConclusionPiolitazone combined with metformin has similar effect to sulphonylurea combined with metformin in controlling blood sugar, but piolitazone combined with metformin has lower incidence of hypoglycemia. Due to limited quality and quantity of the included studies, the above conclusion need to be verified by more high quality studies.
ObjectivesTo systematically review the efficacy of repetitive transcranial magnetic stimulation (rTMS) on rehabilitation of unilateral neglect in stroke patients.MethodsPubMed, The Cochrane Library, PEDro, EMbase, CNKI, WanFang Data and VIP databases were searched online for randomized controlled trials (RCTs) of rTMS on rehabilitation of unilateral neglect in stroke patients from inception to March 2017. Two reviewers independently screened literature, extracted data and assessed the quality of included studies. Meta-analysis was then performed by using RevMan 5.3 software.ResultsA total of 12 RCTs involving 303 patients were included. The results of meta-analysis showed that: the stimulate group was superior to the control group in line bisection test (MD=–5.54, 95%CI –6.79 to –4.29, P<0.000 01), line cancellation test (MD=–3.75, 95%CI –4.60 to –2.90,P<0.000 1) and star cancellation test (MD=–22.94, 95%CI –26.52 to –19.35,P<0.000 01). However, there was no significant difference in the score of the modified Barthel index between two groups (MD=3.91, 95%CI–9.52 to 17.34,P=0.57).ConclusionsrTMS appears to improve the symptoms of unilateral neglect in stroke patients. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusions.
ObjectiveTo systematically review the efficacy of convalescent plasma (CP) in the treatment of coronavirus disease 2019 (COVID-19). MethodsPubMed, EMbase, The Cochrane Library, VIP, WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of CP in the treatment of COVID-19 from inception to September 15th, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, meta-analysis was performed using RevMan 5.4.1 software. ResultsA total of 16 RCTs involving 15 301 patients were included. The results of meta-analysis showed that CP treatment did not reduce mortality compared with no-placebo (RR=0.99, 95%CI 0.93 to 1.05, P=0.63) or normal saline (RR=1.06, 95%CI 0.60 to 1.86, P=0.84). However, compared with standard plasma, the mortality of CP group was lower (RR=0.59, 95%CI 0.37 to 0.95, P=0.03). In addition, compared with no-placebo or normal saline, CP treatment could not improve the clinical condition at 28-30 days, reduce mortality at early treatment and in patients without invasive mechanical ventilation when randomized. ConclusionCurrent evidence shows that compared with no-placebo or normal saline, CP does not reduce mortality in patients with COVID-19. However, when the disease progresses to the point where standard plasma is required, CP may reduce mortality. In addition, use of CP in patients with early or non-critical COVID-19 failed to reduce mortality. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
ObjectiveTo systematically review the efficacy of non-pharmacological interventions to reduce fear of childbirth. MethodsThe Cochrane Library, PubMed, EMbase, Web of Science, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to collect randomized controlled trials (RCTs) of the efficacy of non-pharmacological interventions to reduce fear of childbirth from inception to December 2021. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies; then, a network meta-analysis was performed using Stata 15.0 software. ResultsA total of 19 RCTs involving 3 409 patients were included. Ten non-pharmacological interventions (prenatal education, scenario-based health education, psychological guidance, yoga training, hypnosis, mobile learning education, cognitive behavioral therapy, physical relaxation guidance, breathing guidance, and usual care) were included. The results of the reticulated meta-analysis of the Wijma Delivery Expectancy Questionnaire (W-DEQ-A) showed that the rankings of the interventions were as follows: prenatal education > yoga training > cognitive behavioral therapy > situational simulation health education > psychological guidance > physical relaxation guidance > conventional care. The results of the Wijma Experience of Childbirth Questionnaire (W-DEQ-B) mesh meta-analysis showed that the rankings of the interventions were as follows: mobile learning education > prenatal education > scenario-based health education > cognitive behavioral therapy > breathing instruction > hypnosis > psychological instruction > physical relaxation instruction > usual care. ConclusionThe current evidence suggests that prenatal education, mobile learning education, situational simulation health education, and yoga training may be effective interventions in improving maternal fear of childbirth. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the effect of intermittent fasting on type 2 diabetes mellitus. MethodsThe CNKI, WanFang Data, VIP, CBM, PubMed, Web of Science, The Cochrane Library and EMbase databases were electronically searched to collect randomized controlled trials (RCTs) on intermittent fasting intervention in the treatment of type 2 diabetes mellitus from inception to April 2022. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. The RevMan 5.4 software and Stata 17.0 software were used for meta-analysis. ResultsA total of 17 RCTs comprising 1 428 patients with type 2 diabetes mellitus were included. The results of meta-analysis showed that intermittent fasting improved body weight (WMD=?2.84, 95%CI ?3.79 to ?1.88, P<0.05), body mass index (BMI) (WMD=?1.07, 95%CI ?1.52 to ?0.61, P<0.05), glycosylated hemoglobin levels (SMD=?0.78, 95%CI ?1.19 to ?0.38, P<0.05), and fasting glucose levels (SMD=?0.65, 95%CI ?1.01 to ?0.3, P<0.05). ConclusionThe current evidence suggests that intermittent fasting improves body weight, BMI, glycated hemoglobin, and fasting blood glucose levels in patients with type 2 diabetes. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
