Objective To compare the efficacy and safety of aspirin and rivaroxaban in the prevention of venous thromboembolism (VTE) after total knee arthroplasty (TKA). Methods Eight databases were searched, including Cochrane Library, Embase, Web of Science, PubMed, SinoMed, Wanfang, Chongqing VIP, and China National Knowledge Infrastructure. The search period was from the establishment of databases to June 2023. All randomized controlled trials of aspirin and rivaroxaban for the prevention of VTE after TKA were collected, and meta-analysis was conducted using RevMan 5.3 software. Results A total of 7 articles were included, with a publication period from 2014 to 2022, including a total of 714 patients, including 356 in the aspirin group and 358 in the rivaroxaban group. The meta-analysis results showed that the incidence of deep venous thrombosis in the lower limbs of the aspirin group was higher than that of the rivasarb group [relative risk (RR)=1.53, 95% confidence interval (CI) (1.09, 2.16), P=0.01], and the incidence of bleeding complications was lower than that of the rivaroxaban group [RR=0.66, 95%CI (0.52, 0.82), P=0.0003]. There was no statistically significant difference in the incidence of wound complications between the two groups (P>0.05). Conclusion The efficacy of rivaroxaban in preventing VTE after TKA is better than that of aspirin, but there is an increased risk of bleeding complications.
Objective To evaluate the current situation of randomized controlled trials/ clinical controlled trials (RCT/CCT) on chronic gastritis and whether it could offer reliable evidence for clinical practice in China. Method RCT/CCT on chronic gastritis from eight Chinese clinical journals were searched manually and assessed according to international standard. Results 823 issues containing 213 therapeutic articles were searched and 81 RCT/CCT were identified and assessed. Conclusions The quantity and quality of RCT/CCT on Chronic gastritis in China could not meet the need of clinical practice. RCT/CCT of western medical therapy are much better than those of traditional Chinese therapy and integrated traditional Chinese and western medical therapy ones.
ObjectiveTo investigate the socioeconomic benefits of enhanced recovery after surgery (ERAS) in perioperative period of selective laparoscopic cholecystectomy (LC) by prospective, randomized, controlled clinical study.MethodsA total of 90 patients were recruited in the Hetian Regional People’s Hospital from November 1, 2019 to December 25, 2019. PASS 11 software was used to calculate the sample size. They were grouped into an ERAS group and a tradition group by 1∶1 by random digital table. The patients in the ERAS and the tradition groups were treated with ERAS conception and traditional method respectively during the perioperative period. The postoperative hospitalization time, the first feeding time, the first getting out of bed time, and the first anal exhaust time after operation; the total hospitalization costs, intraoperative infusion, and postoperative total infusion; the intraoperative anesthesia intubation method, trocar layout, and operation time; the pain points of 6 h,12 h and 24 h after operation; the nausea and vomiting after operation; complications and re-hospitalization rate within 30 d after operation were compared between two groups.ResultsA total of 86 patients finally were included in the study, including 44 cases in the ERAS group and 42 cases in the tradition group. The basic data such as the gender, age, body mass index, etiology, blood routine, liver and kidney functions, etc. between the two groups were not statistically significant (P>0.05). Between the two groups, there were no significant differences in the intraoperative anesthesia intubation method, trocar layout, and operation time (P>0.05). Compared with the tradition group, the hospitalization time, the first feeding time, the first getting out of bed time, and the first anal exhaust time after operation were shorter (P<0.05); the total hospitalization costs, intraoperative infusion, and postoperative total infusion were less (P<0.05); the pain points of 6 h,12 h and 24 h after operation were lower (P<0.05); and the times of nausea and vomiting after operation were less (P<0.05) in the ERAS group. There were no complications such as the intraperitoneal bleeding, biliary leakage, and infection after operation, and no re-hospitalized patients within 30 d in both groups.ConclusionApplication of ERAS conception in selective LC perioperative period in Hetian Regional People’s Hospital of Xinjiang Uygur Autonomous Region cannot only shorten postoperative hospitalization time, reduce costs of hospitalization, help to overcome poverty, but also reduce occurrence of complications such as pain, nausea and vomiting, etc.
Although the evidence from randomized controlled trials (RCTs) is regarded as a golden standard, it often fails to be applied in clinical practice for lack of generalizability. Evidence from either RCTs or non-RCTs is mutually complementary and referred. Different designs are suitable for different stages and can resolve different issues. During evaluation of an intervention, the proper research design should be selected in accordance with the objective, feasibility, and merits and limitations of different design modes.
Objective To assess the effect and safety of Dalitong Granule in the treatment of the Piman syndrome (functional dyspepsia). Method The double-blind, double-dummy and randomized controlled method was adopted. 120 patients were randomized to the treatment group (n=90, Dalitong Granule 6 g, tid) and the control group (n=30, treated with cisapride 5 mg, tid). The therapeutic course for both groups was 2 weeks. Results All the results were analyzed on the basis of intention-to-treat and per-protocol population. In the treatment group, the markedly effective rates were 62.37% and 64.45% respectively. The effective rates were 99.55% and 96-67% respectively. In the control group, the markedly effective rates were 58-08% and 60.00% respectively. The effective rates were 90.33% and 93.33% respectively. There was no significant difference between two groups (Pgt;0.05). For effects on Piman syndrome, in the treatment group, the markedly effective rates were 53.76% and 55.56% respectively. The effective rates were 86.02% and 88.89% respectively. In the control group, the markedly effective rates were 48.38% and 50.00% respectively. The effective rates were 80.64% and 83.33% respectively. The results showed no statistical significance difference between two groups (Pgt;0.05). For effects on gastric emptying function (PP population), in the treatment group, the markedly effective rate and effective rate were 72.42% and 79.32%. In the control group those were 64.28% and 64.28%. There was no significant difference between the two groups (Pgt;0.05). ITT and PP analysis revealed similar results. No adverse effect was found in the observation. Conclusions Dalitong granule has the same clinical effect as cisapride with no obvious toxic-adverse effects.
Objective To systematically evaluate the effectiveness and safety of Puerarin on diabetic peripheral neuropathy. Methods A systematic review and evaluation of all available relevant randomized or quasi-randomized controlled trials of Puerarin for diabetic peripheral neuropathy from Cochrane Controlled Trials Register (150 issue of 2003), Medline (1966-2003. 2), EMbase (1984-2001. 12. 4), and the Chinese Biological Medicine Database (1978-2003. 2) were performed. The selection of studies, data extraction, and assessment of methodological quality were performed independently by two reviewers. The following outcomes were assessed: effectiveness of clinical symptoms, sensory nerve and motor nerve conduction velocities, and severe adverse events of Puerarin. Results Ten randomized controlled clinical trials including 726 patients met the inclusion criteria. At the end of the treatment, compared to general treatment or vitamin B, Puerarin showed significant positive effects on the total effect rate of therapy and increased peripheral nerve conduction velocity. No severe adverse events were observed during the treatment period. However, most included trials show some degree of study design or analysis defect. Conclusions Our analysis suggests that Puerarin appears to be an effective and safe treatment for diabetic peripheral neuropathy. However, due to the low quality trials included in this review, more rigorously designed, randomized, double-blind, placebo-controlled trials of Puerarin for diabetic peripheral neuropathy are needed to further assess its usefulness in diabetes peripheral neuropathy patients.
Objective To systematically evaluate the effect of psychological intervention on the survival outcome of breast cancer patients. Methods PubMed, Web of Science, China National Knowledge Infrastructure, Wanfang, Chongqing VIP were searched by computer. The search time ranged from the establishment of the databases to December 31, 2024. Randomized controlled trials of psychological intervention related to breast cancer were searched, and the studies that met the criteria were qualitatively described and meta-analyzed. Results A total of 11 randomized controlled trials were included. Meta-analysis included five studies, and the results showed that the survival rate of breast cancer patients receiving psychological intervention had no significant difference compared with breast cancer patients receiving only conventional treatment (P＞0.05). Meta-analysis of 3 studies involving early and middle stage breast cancer patients showed that there was no significant difference in survival rate between breast cancer patients receiving psychological intervention and breast cancer patients receiving only conventional treatment (P＞0.05). The qualitative analysis of the impact of psychological intervention on the survival of breast cancer patients showed that 3 studies found that psychological intervention could improve the survival of breast cancer patients, and the main outcome was to prolong the median survival or average survival. ConclusionsQualitative analysis shows that psychological intervention may improve the survival period of breast cancer patients. Due to the limited number of included studies and small sample size, the meta-analysis results failed to provide sufficient evidence that psychological intervention can improve the survival outcome of breast cancer, and this result needs further verification.
Objective To appraise the current situation of randomized controlled trials (RCTs) on information of common-used digestive-related medicines afforded by medicine-salesmen. Methods RCTs on digestive-related medicines were assessed according to clinical epidemiologic standard. Results 60 medicines containing 252 therapeutic articles were searched and 75 RCTs were identified and assessed. Conclusion The qualities and quantities of RCTs of information on digestive-related medicines were of large difference, the RCTs afforded by the joint pharmaceutical enterprises are much better than those of foreign ones and domestic ones.
Objective To evaluate the clinical efficacy of dexmedetomidine in perioperative management of on-pump cardiac surgery. Methods Randomized controlled trials (RCTs) were identified through a systematic literature search of PubMed, EBSCO, Web of Science, Cochrane Library, CBM, CNKI, Wanfang Database (up to December 2016). RevMan 5.3 software was used for meta-analysis. Results Sixteen studies with 1 432 patients were included. Dexmedetomidine significantly decreased the risk of postoperative delirium (RR=0.28, 95% CI 0.18 to 0.44, P<0.000 01) and postoperative atrial fibrillation (RR=0.65, 95% CI 0.44 to 0.98, P=0.04) compared with the controls. The duration of intubation (RR=–1.96, 95% CI –2.07 to –1.86, P<0.000 01), length of ICU stay (RR=–0.49, 95% CI –0.74, –0.24, P=0.000 1) and hospital stay (RR=–1.24, 95% CI –2.26 to –0.22, P=0.02) in the dexmedetomidine group were significantly shorter than those of the control group. In addition, dexmedetomidine was shown to improve the score of the the Montreal Cognitive Assessment (RR=0.88, 95% CI 0.42 to 1.35, P=0.000 2) compared to the control group. Conclusion Dexmedetomidine can reduce the complications after cardiac surgery, which is safe and effective. However, more studies with good methodologic quality and large samples are still needed to make further assessment.
ObjectivesTo systematically review the efficacy and safety of mechanical thrombectomy for patients with acute ischemic stroke in different ages.MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) on the efficacy and safety of mechanical thrombectomy for patients with acute ischemic stroke in different ages from inception to August, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 13 studies involving 2 995 patients were included. The results of meta-analysis showed that compared with the control group, patients aged 80 and above had no statistically significant difference in reperfusion success rates (OR=0.90, 95%CI 0.71 to 1.14, P=0.378), and incidence of symptomatic intracranial hemorrhage (OR=1.30, 95%CI 0.86 to 1.94, P=0.212), however, with higher incidence of arbitrary intracranial bleeding events (OR=1.61, 95%CI 1.28 to 2.04, P<0.001), 3-month mortality (OR=2.14, 95%CI 1.73 to 2.64, P<0.001) and lower good functional prognosis rate at 3 months (OR=0.46, 95%CI 0.30 to 0.71, P<0.001).ConclusionsCurrent evidence suggests that people aged 80 and above can obtain effective perfusion through mechanical thrombectomy, however, the incidence of postoperative adverse outcome events is higher and the prognosis is relatively poor. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
