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 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 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.
Objective To explore the effect of different nutrition on the immune function of patients with colorectal cancer. Methods A total of 640 colorectal cancer patients were randomized into the enteral nutrition and peripheral nutrition groups. The peripheral venous blood was sampled before operation and on the postoperative days 1 and 7 to determine the serum levels of IgG, IgA, IgM, the percentage of T lymph cell subgroups CD3, CD4, CD4/CD8 and CRP, PGE, α- antitrypsin etc. The patient’s general condition, side-effects, and complications were observed intimately after surgery. Results Compared with the control group, the IgG, IgA, IgM, CD3, CD4,CD4/CD8 levels of the trial group on postoperative day 7 were higher. But the levels of CRP, PGE, α- antitrypsin were decreased. Hospitalization time and anal exsufflation time were shorter as well. There was no significant difference in either the general conditions or complications between the two groups. Conclusion Application of enteral nutrition after colorectal cancer surgery is safe, ,effective, and can improve the patient’s immune function and prognosis.
ObjectiveTo explore the clinical features of atypical bronchial asthma with chief complaint of palpitations. MethodsTwelve cases with unexplained palpitations diagnosed by asthma were analyzed retrospectively. ResultsThe patients were diagnosed with asthma through bronchodilation test,skin prick tests,fractional exhaled nitric oxide (FeNO) and diagnostic treatment.The ratio of male to female cases was 1:5. The ventilation lung function of all patients was in normal range. The median time of misdiagnosis was 13.5(3-120) months. 41.6% of cases had dust mite positive skin prick test. The median value of FeNO was 32.75(18-54) ppb. The symptoms of all patients were relieved completely after standard treatment. ConclusionPalpatation may be a specific presentation of asthma characterized with eosinophilic airway inflammation which may be misdiagnosed as other diseases for a long time,especially in elder women. To improve the knowledge of this kind of atypical asthma,detailed medical history, experimental examinations and diagnostic treatment response are important to confirm the diagnosis in time.
ObjectiveTo explore the predictive value of fractional exhaled nitric oxide (FeNO) in the treatment response of adult asthmatic patients. Methods64 adult outpatients with asthma from Peking Union Hospital between March and September 2013 were recruited in the study. All patients completed asthma control test (ACT) together with exhaled nitric oxide (FeNO) and pulmonary function test. Then the patients were classified into a higher FeNO group (n=33) and a normal FeNO group (n=31) according to FeNO level. All patients accepted regular inhaled ICS/LABA treatment (salmeterol and fluticasone 50/250). Three months later all patients reaccepted ACT,FeNO and pulmonary function test. ResultsThe ACT score increased in all patients,and was significantly higher in the higher FeNO group than that in the normal FeNO group[22.07±5.49 vs. 19.23±5.48,t=2.893,P<0.05]. The complete control rate of the higher FeNO group was higher than that in the normal FeNO group (42.42% vs. 19.35%,χ2=3.960,P<0.05). The FEV1 and FEV1%pred of two groups both increased significantly (P<0.05),but there was no significant difference between two groups (P>0.05). Correlation analysis showed that FeNO and the declined rate of FeNO was negatively correlated with the ACT score(r=-0.302,P<0.05;r=0.674,P<0.01) and positively correlated with the improvement of ACT score (r=0.514,P<0.01;r=0.674,P<0.01). No significant correlation was found between FeNO and FEV1 or FEV1%pred. ConclusionThe effect of ICS/LABA therapy is better for asthma patients with higher FeNO. FeNO can be used for predicting the response to ICS/LABA therapy in patients with asthma and guiding the treatment.
