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 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 provide evidence of the role of helicobacter pylori eradication in the treatment of functional dyspepsia. Methods We searched VIP, CBMdisc, MEDLINE and The Cochrane Library for systematic reviews, meta-analysis, randomized controlled trials and clinical guidelines involving helicobacter pylori and functional dyspepsia, so as to provide the best evidence for clinical practice. Results We included two systematic reviews, one meta-analysis and eleven randomized controlled trials. The evidence identified showed that helicobacter pylori infection was more prevalent in functional dyspepsia than in asymptomatic patients, but the effect of H pylori infection in the pathogenesis of functional dyspepsia remained controversial. H pylori eradication therapy had a relatively weak effect in H pylori positive functional dyspepsia. An economic model suggested that this modest benefit may still be cost-effective, but more studies are needed to assess this. Conclusion According to the current evidence, it can be concluded that helicobacter pylori eradication for the treatment of functional dyspepsia should be individualized.
Objective To assess the efficacy and safety of Chinese herbal medicine for the treatment of functional dyspepsia (FD) and compare the difference of efficacy between Chinese herbal medicine and western medicine. Methods Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Central Register of Controlled Trials, MEDLINE, CBMdisc and CNKI from inception to Dec. 2008. And we also handsearched relevant journals and conference proceedings. We evaluated the risk of bias in the included randomized controlled trials(RCTs) according to the Cochrane Handbook for Systematic Reviews. The Cochrane Collaboration’s software RevMan 4.2.8 was used for meta-analysis. Results Seven studies involving 981 patients were identified. The results of meta-analysis showed that: (1) There was no significant difference between Dalitong granule and cisaprid in effective rates (RR=1.03, 95%CI 0.97 to 1.09, P=0.36), piman syndrome (RR=1.06, 95%CI 0.96 to 1.18, P=0.23), gastric emptying function (RR=1.05, 95%CI 0.76 to 1.45, P=0.78), syndromes of TCM (WMD=0.41, 95%CI –1.05 to 1.87, P=0.58), pulse and tongue picture (RR=1.00, 95%CI 0.69 to 1.45, P=0.98), and adverse reaction (RR=1.00, 95%CI 0.69 to 1.45, P=0.46). (2) There was no significant difference between Weishuan pellet and cisaprid on effective rates (RR=1.02, 95%CI 0.96 to 1.07, P=0.53), piman syndrome (RR=1.06, 95%CI 0.97 to 1.15, P=0.19), gastric emptying function (RR=1.05, 95%CI 0.86 to 1.28, P=0.63), syndromes of TCM (WMD=0.70, 95%CI 0.11 to 1.29, P=0.02) and adverse reaction (RR=0.33, 95%CI 0.02 to 5.28, P=0.44). (3) There was no significant difference among Jianpiyiqi prescription (RR=1.16, 95%CI 1.00 to 1.34, P=0.05), Liqifuwei oral liquid (RR=1.00, 95%CI 0.91 to 1.11, P=0.94) and Jianpixiaozhang granules (RR=0.88, 95%CI 0.76 to 1.00, P=0.06) compared with cisaprid in effective rates (Pgt;0.05). (4) There was no significant difference between Hewei Xiaopi Capsule and domperidone on effective rates (RR=1.11, 95%CI 0.87 to 1.41, P=0.42) and piman syndrome (RR=1.07, 95%CI 0.93 to 1.24, P=0.35). Conclusion Chinese herbal medicine has a better clinical cure rate and marks of TCM syndrome on FD than western medicine. But we have no adequate evidence to confirm whether western medicine can be substituted by Chinese herbal medicine for the treatment of FD. Therefore, we need more high quality RCTs to confirm this conclusion.
Objective To evaluate the effectiveness of exercise and rehabilitation program in improving shoulder function and quality of life for breast cancer patients after mastectomy. Method We searched the Cochrane Database of Systematic Reviews, JBI Database of Systematic Reviews, MEDLINE (1966 to 2008), EMbase (1989 to 2007), CINAHL (Cumulative Index to Nursing and Allied Health literature), CBMdisc (1978 to 2008), and CNKI (1994 to 2008) to collect randomized controlled trials (RCTs). The quality of RCTs was critically appraised and data were extracted by 3 reviewers independently. Meta-analyses were conducted for the eligible RCTs. Result Nineteen RCTs were included. Stepwise upper extremity exercise and body exercise were reported in the rehabilitation program. Nine studies indicated that the rehabilitation program significantly improved the shoulder function of breast cancer patients after mastectomy. Four studies demonstrated its effect on cardiopulmonary function and body endurance. Six RCTs proved the effect of rehabilitation program on health-related quality of life and fatigue alleviation. Conclusion Rehabilitation program consisting of stepwise upper extremity exercise and full-body exercise is effective in improving the shoulder function and enhancing the quality of life of breast cancer patients after mastectomy. It also has a positive effect in reducing fatigue for those undergoing chemotherapy or radiotherapy.
ObjectiveTo investigate the feasibility of proton magnetic resonance spectroscopy (1H-MRS) imaging, by which to quantitatively analyze liver fat content for therapeutic evaluation of fatty liver at 3.0 T MRI. MethodsTwenty-six patients who diagnosed with fatty liver were examined with proton MRS at Siemens Trio Tim 3.0 T MRI before treatment and 3, 6 months after treatment, respectively. The water peak, fat peak, water peak area, and fat peak area were detected, and the relative lipid content 1 (RLC1) and relative lipid content 2 (RLC2)were calculated. Fatty liver index (FLI) was referred to the standard which was calculated from triglycerides (TG), gammaglutamyl-transferase (GGT), waist circumference, and body mass index. ResultsThere were significantly different differences of RLC1 and RLC2 among before treatment and 3, 6 months after treatment (Plt;0.05). Compared with before treatment, the RLC1 and RLC2 values significantly decreased on month 3 or 6 after treatment (Plt;0.05). There were positive correlation between RLC1 or RLC2 and FLI (r=0.476, Plt;0.00; r=0.475, Plt;0.001). The intraclass correlation coefficient was more than 0.75 before treatment, the repeatability was better. ConclusionsProton MRS can quantitatively measure liver fat content. It can be reliably used for dynamic monitoring the therapeutic effects for fatty liver. Proton MRS is accurate, and has a good clinical application in dynamically monitoring the progression of fatty liver and evaluating the therapeutic effects of various treatments.
Objective To describe a new technique for digestive tract reconst ruction of total gast rectomy.Methods The modified functional jejunal interposition ( FJ I) was performed in 38 patient s who underwent total gastrectomy between June 2004 and March 2006. At digestive tract reconst ruction, the jejunum with suitable suture ligated at 2 cm distal to side-to-end jejunoduodenostomy was changed to sew up 2－3 needles and to narrow it . End-to-side esophagojejunostomy to Treitz ligament was shortened to 20－25 cm befittingly. Side2to2side jejunojejunostomy to Treitz ligament was 10 cm. Both esophagojejunostomy and jejunojejunostomy must not be tensioned. Results No patients died or had anastomotic leakage in perioperative period. Roux-en-Y stasis syndrome (RSS) was in 2 patients. The Visick grade: 35 patient s were grade Ⅰ, 3 patient s were grade Ⅱ. Serum nut ritional parameters in 2 patients hemoglobin was only lower than normal. At 6 months after operation , food intake per meal and body weight were recovered to the preoperative level in 36 patients, and only 2 patients appeared weight worse. One patient had reflux esophagitis and no dumping syndrome occurred. Through the upper gast rointestinal radiograph , the bariums entered into duodenal channels mostly , and a little into the narrow channels. Conclusion The modified FJ I not only reserved all advantages of the primary procedure , but also could further lower the complications and improve of the quantity life of the patients who were underwent total gast rectomy. It would be necessary for further prospective randomized controlled trial in tlhe largescale cases.
Objective To evaluate the clinical appliance and significance of the technique of anorectal manometry. Methdos Different ways of anorectal manometry, domain of its appliance and its clinical appliance was summarized and reviewed. Results The technique of anorectal manometry not only has important value on the study of analrectal pathology and physiology, but also can be associated with other examinations to manage biofeedback therapy, diagnose all kinds of anorectal diseases and evaluate anorectal function. Conclusion Anorectal manometry is a safe, simple, harmless and impersonal examination technique. It is necessary in the examination of analrectal function, in the diagnosis and treatment of anolrectal diseases.
Objective To evaluate clinical outcomes of mild-to-moderate or moderate functional mitral regurgitation（FMR）after aortic valve replacement （AVR） in patients with severe aortic stenosis （AS），and analyze prognostic factors of these patients with mild-to-moderate or moderate FMR （2＋to 3＋）. Methods From September 2008 to December 2011，a total of 156 patients with severe AS （peak aortic gradient （PAG）≥50 mm Hg） as well as FMR （2＋to 3＋） underwent surgical treatment in Zhongshan Hospital. There were 95 male and 61 female patients with their average age of 59.2±10.5 years. Detailed perioperative clinical data were collected，and postoperative patients were followed up. The ratio of FMRpreoperative/FMR postoperative was calculated. Patient age，gender，body weight，history of hypertension，ventricular arrhythmia，atrial fibrillation （AF），left ventricular ejection fraction （LVEF），left ventricular end-diastolic diameter （LVEDD），left atrial diameter （LAD），pulmonary artery hypertension （PAH），PAG were assessed by logistic multivariate regression analysis. Results Six patients died postoperatively，including 4 patients with low cardiac output syndrome and 2 patients with refractory ventricular arrhythmia. Perioperative mortality was 3.8%. The average follow-up time was 20.3±8.5 months and follow-up rate was 85.3% （133/156）. Eight patients died during follow-up，including 3 patients with heart failure，2 patients with ventricular arrhythmia，and 3 patients with anticoagulation-related cerebrovascular accident. Multivariate regression analysis showed that FMR preoperative/FMR postoperative ratio was not correlated with age≥55 years，male gender，body weight≥80 kg，LVEDD≥55 mm，LVEF≤50%，history of hypertension or ventricular arrhythmia. However，LAD≥50 mm，PAH≥50 mm Hg，PAG≤75 mm Hg and preoperative AF were negatively correlated with postoperative FMR improvement. Conclusions Risk factors including LAD≥50 mm，PAH≥50 mm Hg，PAG≤75 mm Hg and preoperative AF are negatively correlated with postoperative improvement of FMR （2＋to 3＋）. Patients with severe AS and above risk factors should receive concomitant surgical treatment for their FMR during AVR，since preoperative FMR（2＋to 3＋）usually does not improve or even aggravate after AVR.
