Objective To evaluate the clinical effectiveness of helicobacter pylori (HP) eradication in treating functional dyspepsia (FD) patients with HP infection. Methods The randomized controlled trials (RCTs) about HP eradication vs. general treatment for FD patients published by April, 2012 were searched in the following databases: CBM, CNKI, WanFang Data, PubMed, Ovid, EMbase and The Cochrane Library (Issue 1, 2012). According to the inclusion and exclusion criteria, two reviewers independently screened studies, extracted data, and evaluated the methodological quality. Then the meta-analysis was conducted using RevMan 5.1 software. Results The total 14 RCTs were included. Among all 2 665 patients involved in, 1 339 were in the treatment group, while the other 1 326 were in the control group. The results of meta-analysis showed that HP eradication was superior to general treatment for FD patients in clinical effects (RR=3.90, 95%CI 3.08 to 4.94, Plt;0.000 01), symptomatic score (WMD=−1.68, 95%CI −1.88 to −1.47, Plt;0.000 01), and improvement of upper abdominal pain (RR=2.84, 95%CI 2.02 to 3.99, Plt;0.000 01). Conclusion With obviously clinical effects, HP eradication can decrease the symptomatic score of dyspepsia, and especially improve upper abdominal pain. For the quality and quantity limitations of the included studies, more well-designed and double blind RCTs are required to further prove this conclusion.
Objective To evaluate the effects of saxagliptin on β cell function of type 2 diabetic patients. Methods The Cochrane Library, PubMed, EMbase, CBM, VIP, and CNKI were searched from their establishment to November, 2011, for relevant randomized controlled trials on the effects of saxagliptin on β cell function in type 2 diabetic patients. Language was limited to Chinese and English only. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and evaluated and cross-checked the methodological quality. Then meta-analysis was conducted using RevMan 5.0 software. Results Five RCTs were included. The results of meta-analysis showed that: HOMA-B was significantly increased in the saxagliptin (or saxagliptin plus routine treatment) 2.5 mg, 5 mg, and 10 mg groups (MD=8.03, 95%CI 4.57 to 11.48, Plt;0.000 01; MD=7.50, 95%CI 4.27 to 10.73, Plt;0.000 01; MD=17.45, 95%CI 13.93 to 20.97, Plt;0.000 01); HOMA-IR was similar between saxagliptin 2.5 or 10 mg group, and control group (MD= –0.05, 95%CI –0.18 to 0.08, P=0.47; MD= –0.18, 95%CI –0.60 to 0.24, P=0.4). Conclusion Current evidence shows that saxagliptin is effective in improving β cell function and insulin resistance. Due to short follow-up and small sample size, this conclusion has to be further proved by more high-quality RCTs.
Objective To investigate the injury types, dysfunction situation and rehabilitation deamnd of the Lushan earthquake victims. Methods The rehabilitation demand of 208 Lushan earthquake victims in the West China Hospital of Sichuan University were investigated using a questionnaire. Results Bone fractures accounted for the largest proportion of injury types, followed by combined injuries, soft tissue injuries, pulmonary contusion, and amputation. Most victims suffered from the motor dysfunction, balance disorder and restrictions in activities of daily living. More than 80% of victims had pain. A few victims had paresthesia and respiratory disorder. Most victims needed rehabilitation assistant devices and hospitalization treatment. Conclusion The injury types and dysfunction situation of Lushan earthquake victims are associated with the demand of rehabilitation assistant device. The tailored rehabilitation regimen can be made in combination with victim’s rehabilitation demand. The early intervention of rehabilitation medicine is extremely beneficial to the recovery of earthquake victims.
Objective To collect the clinical data of victims with traumatic brain injury (TBI) admitted in the West China Hospital of Sichuan University within 2 weeks after 4.20 Lushan earthquake, and to analyze their clinical characteristics and effects of early rehabilitation, so as to provide baseline data for rescue TBI victims with the early rehabilitation treatment during emergency medical rescue. Methods A total of 392 victims admitted in the hospital from April 20th, 2013 to May 3rd, 2013 were screened, of which the TBI victims were clinically assessed and treated with early rehabilitation. Then both the activities of daily living (ADL) and the Rancho Los Amigos Cognitive Recovery Scale (RLA) before and after the treatment were analyzed. The data were input by Excel software, and the statistical analysis was performed by SPSS softwar. Results A total of 51 TBI victims at age from 3 to 84 years old were included finally. The categories of TBI included subarachnoid hemorrhage (41.2%), intracranial hematoma (33.3%) and mixed type (33.3%), and the severity were associated with the type of TBI. The GCS score of cerebral concussion was higher (13.25 ± 0.62) while that of the diffuse axonal injury was lower (4.50 ± 0.71). All victims (100%) had limited ADL, 74.51% had cognitive dysfunction, 9.80% had speech disorder, and 7.84% had dysphagia. After the early rehabilitation treatment, both ADL (before treatment: 34.82 ± 58.29, after treatment: 69.63 ± 22.29) and RLA (pre-treatment: 4.16 ± 1.24, treatment: 7.20 ± 1.69) were obviously higher than those before treatment, with statistical differences (both P lt;0.05). Conclusion The TBI categories of Lushan earthquake victims are various and mixed, and the severity associated with the type of TBI. All TBI victims are accompanied with more clinical problems and functional limitation. Early rehabilitation treatment is safe and effective to improve ADL and RLA as well.
Objective To investigate the patient’s psychological anticipation and occurrence of chemotherapy-induced nausea and vomiting (CINV), and to assess the influence of CINV on quality of life, so as to provide evidence for clinical doctors to recognize and pay attention to CINV. Methods The patients in the Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology who took either moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC) were randomly sampled with a questionnaire for two circles. Patients were asked to record the following indexes before chemotherapy, on the second day and the sixth day of chemotherapy: acute and delayed nausea and vomiting, independently taking antiemetics, and functional living index-emesis (FLIE). Then, descriptive analysis and multiple linear regression analysis were adopted for the outcomes of investigation. Results A total of 344 patients were investigated, of which 303 fulfilled the questionnaire finally. For the single-day chemotherapy, the acute nausea and vomiting, delayed nausea vomiting and overall complete remission in the MEC group were 86.1%, 76.6%, and 71.5%, respectively; while those of the HEC group were 84.1%, 71.0%, and 66.7%, respectively. For the multi-day chemotherapy, the acute nausea and vomiting, delayed nausea vomiting and overall complete remission were 93.8%, 64.9%, and 64.9%, respectively. Patients’ expectation of nausea and anticipatory anxiety was closely related to the delayed nausea in their prior circle of chemotherapy. Based on the FLIE assessment, about 30% of all patients reported reduced daily living function. Conclusion CINV remains a significant problem among patients in China, especially in controlling the reaction during delayed phase and nausea as well. It requires that more attention should be paid to CINV and more effective prophylaxis should be adopted in clinical practice.
Objective To systematically evaluate the orthotic effect of functional electrical stimulation (FES) on the improvement of walking in stroke patients with foot drop. Methods The randomized controlled trials (RCTs) that investigated the orthotic effect of FES on walking in stroke patients with foot drop were electronically searched in the databases such as PubMed, Web of Science, The Cochrane Library (Issue 1, 2013), EMbase, CBM, CNKI, VIP and WanFang Data from January 2000 to January 2013, and the relevant references of included papers were also manually searched. Two reviewers independently screened the trials according to the inclusion and exclusion criteria, extracted the data, and assessed the methodology quality. The meta-analyses were performed using RevMan 5.1 software. Results A total of 8 RCTs involving 255 patients were included. The results of meta-analyses on 4 RCTs showed that, compared with the conventional rehabilitation intervention, the functional electrical stimulation could significantly improve the walking speed, with significant difference (MD=0.09, 95%CI 0.00 to 0.18, P=0.04). The other indicators were only descriptively analyzed due to the incomplete data. Conclusions Functional electrical stimulation is effective in improving walking speed, but it is uncertain of other therapeutic indicators. So it should be further proved by conducting more high quality, large sample and multi-center RCTs.
Objective To objectively evaluate the effectiveness of Tai Chi in fall prevention and balance function in the elderly. Methods Databases such as PubMed, Web of Science, The Cochrane Library (Issue 8, 2012), EMbase, CBM, CNKI, VIP and WanFang Data were electronically searched to collect the randomized controlled trials (RCTs) published from 2000 to 2012, and the relevant references of the included articles were also manually searched. According to the inclusion and exclusion criteria, the literature was screened, the data were extracted and the methodological quality of the included studies was assessed. Then meta-analyses were performed by using RevMan 5.1 software. Results A total of 6 RCTs involving 2 796 participants were included. The results of meta-analyses showed that the Tai Chi group was superior to the control group in decrease of the incidence rate of fall (RR=0.82, 95%CI 0.73 to 0.92, P=0.000 6), Timed Up and Go Test (MD=0.71, 95%CI 0.29 to 1.12, P=0.000 9), Functional Reach Test (MD=0.78, 95%CI 0.33 to 1.23, P=0.000 7) and Berger Balance Scale (MD=2.45, 95%CI 1.47 to 3.43, Plt;0.000 01), and there were statistical differences. Conclusion Tai Chi can effectively reduce the risk of fall for the elderly and improve their balance function.
Objective To explore the status of women’s quality of life and analyze risk factors related diminished ovarian reserve (DOR). Methods We applied the method of convenient sampling to investigate 61 patients with DOR (DOR group) and 60 women with normal ovarian reserve function (control group) who visited a reproductive centre of a Triple-A hospital from February to May 2013, using a questionnaire which included basic information table, Menopausal Quality of Life Scale (MENQOL) and SF-36 Health Survey for quality of life, and Kupperman Index Scale (KI) for the degree of clinical symptoms. Then, statistical analysis was performed using SPSS 17.0 software. Results Compared with the control group (43.60±16.82), the level of women’s quality of life in the DOR group (73.42±24.15) was significantly lower (Plt;0.01), while the degree of clinical symptoms was significantly higher (Plt;0.01). There were positive associations between quality of life and degree of clinical symptoms. The risk factors related to DOR were various such as age, weight, quality of sleep, menstrual disorders, number of abortion, age of the first pregnancy, gynecologic surgery, economic income, education, family relationship, unsatisfactory sexual life, and psychological factors. Conclusion In order to improve women’s quality of life, effective treatment should be conducted to relieve clinical symptoms of women with DOR. Good life style, harmonious family relationship, healthy mind and avoiding the risk factors, which could effectively help the prevention and treatment of the disease.
Objective To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in treating stroke patients with motor dysfunction. Methods The Cochrane Library, MEDLINE, EMbase, CBM, CNKI and WanFang Data were searched from inception to January 2012, and the references of the included studies were also retrieved to collect the randomized controlled trials (RCTs) on rTMS in treating stroke patients with motor dysfunction. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Then meta-analysis was performed using RevMan 5.0.2 software, and evidence quality and recommendation level were assessed using the GRADE system. Results A total of 11 RCTs involving 376 patients were included. The results of meta-analysis (including 3 RCTs, low quality) showed that, compared with the routine rehabilitation treatment, 2 to 4 weeks of rTMS was much beneficial to stroke patients with motor dysfunction, with significant differences (WMD=11.02, 95%CI 2.56 to 19.47). The other 8 studies only adopted descriptive analysis accordingly. Conclusion It is still uncertain of the effectiveness of rTMS in improving motor dysfunction of stroke patients, so rTMS should be applied with caution in clinic.
Objective To conduct Meta-analyses on published literatures about the Jianpi Bushen Decoction combined with western medicine for dysfunctional uterine bleeding (DUB), so as to evaluate its efficacy and safety compared with the western medicine treatment. Methods The following databases such as PubMed (1995 to 2011), EMCC (1995 to 2011), CBM (1995 to 2011), CNKI (1995 to 2011), Wanfang (1989 to 2011) and VIP (1989 to 2011) were searched to collect the randomized controlled trials (RCTs) on Jianpi Bushen Decoction combined with western medicine for DUB. The selection of studies, assessment of methodological quality and data extraction were performed independently by two reviewers according to the Cochrane systematic review methods, and Meta-analyses were performed by using RevMan5.0 software. Results A total of 12 RCTs involving 925 cases were included, of which 471 ones were in the experimental group while the other 454 ones were in the control group. Each study was comparable in baseline data, all with reporting of using random methods, but no mention of detailed random methods, blind methods and allocation concealment. The results of Meta-analyses indicated that compared with single therapy of western medicine, Jianpi Bushen Decoction combined with western medicine for DUB was superior in the total effective rate (OR=5.60, 95%CI 3.25 to 9.67, Plt;0.000 01), bleeding recovery rate (OR=3.79, 95%CI 2.70 to 5.32, Plt;0.000 01), and bleeding recurrence rate (OR=0.14, 95%CI 0.05 to 0.42, P=0.000 5), with significant differences. Conclusions The integrated treatment of Jianpi Bushen Decoction and western medicine has certain effects on dysfunctional uterine bleeding, and it may be a promising treatment option. Due to the poor quality and high possibility of bias of the included studies, more well-designed multi-centered RCTs should be performed.
