ObjectiveTo discuss the role of imatinib preoperative chemotherapy in treatment of advanced gastrointestinal stromal tumor(GIST). MethodThe related literatures about imatinib preoperative chemotherapy for GIST were reviewed. ResultsImatinib preoperative chemotherapy is an effective treatment for advanced GIST, which significantly improve the resection rate and prolong the overall survival time for patients with advanced GIST. ConclusionsPreoperative imatinib treatment has good effect for metastatic or locally advanced GIST. It should be individualized by gene type of the GIST, which is deserved to be further studied.
ObjectiveTo analyze the significance of application of pulse indicated continuous cardiac output (PICCO) as hemodynamic monitoring for low cardiac output patients after coronary artery bypass grafting (CABG) operation. Method We retrospectively analyzed the clinical data of 110 patients conducted non-extracorporeal circulation CABG operation in Beijing Anzhen Hospital between June 2013 and October 2014. The patient were divided into two groups including a PICCO applied group and a non-PICCO applied group. There were 49 patients including 29 males and 20 females at average age of 60.80±9.34 years in the PICCO group. There were 61 patients with 37 males and 24 females at age of 62.22±10.41 years in the non-PICCO group. We compared the treatment effects between the two groups. ResultsComparing to the non-PICCO group, the PICCO group had shorter average days of postoperative intra-aortic balloon pump (IABP) usage (t=2.155, P=0.039), less usage rate of endotracheal reintubation (χ2=5.098, P=0.039), shorter average postoperative mechanical ventilation time (t=2.087, P=0.044), less occurrence rate of cardiac arrhythmia (χ2=4.011, P=0.045), less occurrence rate of multiple organ dysfunction syndrome (MODS) (χ2=5.075, P=0.035), shorter days in ICU (t=2.141, P=0.040) and in-hospital time (t=2.061 P=0.048). During monitoring, the PICCO group had slower average heart rate, higher average arterial pressure, lower blood lactate, greater oxygenation and greater left ventricular ejection fraction (LVEF) than those in the non-PICCO group. ConclusionThe application of PICCO reduces occurrence of postoperative complications for low cardiac output patients with post coronary artery bypass grafting operation, increases cure rate.
ObjectiveTo determine the benefits and harms of mechanical bowel preparation(MBP) in elective colorectal surgery. MethodsCochrane systematic evaluation was used to search through Cochrane libraries of clinical comparative trials, PubMed, Embase, Cancer Lit, and the Chinese BioMedical Literature on disc. The quality of literatures was independently evaluated and cross-checked by two evaluators, indicator for assessment including anastomotic leak, overall surgical site infection(SSI), extra-abdominal septic complications, wound infections, reoperation or second intervention rate, and death. The results were analysed with RevMan 5.1 software. ResultsFourteen RCTs were included in this analysis with a total number of 5 373 patients. Comparing with no MBP for elective colorectal surgery, the study results showed that MBP had not reduce any postoperative complications when concerning anastomotic leak[OR(95% CI), 1.08(0.82-1.43);P=0.56];overall SSI[OR(95% CI), 1.26(0.94-1.68);P=0.12];extra-abdominal septic complications[OR(95% CI), 0.98(0.81-1.18);P=0.81];wound infections[OR(95% CI), 1.21(1.00-1.46);P=0.05];reoperation or second intervention rate[OR(95% CI), 1.11(0.86-1.45);P=0.42], and death[OR(95% CI), 0.97(0.63-1.48);P=0.88]. ConclusionNo evidence supporting the use of MBP in patients undergoing elective colorectal surgery. MBP should be omitted in routine clinical practice.
ObjectiveTo systematically evaluate the effects of vitamin D supplementation on fasting blood glucose, insulin resistance, β cell function in type 2 diabetes mellitus. MethodsDatabases including PubMed, The Cochrane Library (Issue 12, 2015), Web of Science, ScienceDirect Online, VIP, CNKI, WanFang Data, and CBM were searched to collect randomized controlled trials (RCTs) about vitamin D supplementation for type 2 diabetes mellitus from inception to December 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was conducted by RevMan 5.3 and Stata12.0 softwares. ResultsA total of 22 RCTs involving 1 756 patients were included. The results of meta-analysis showed that, compared with the control group, the vitamin D supplementation group had a significant improvement in insulin resistance (SMD=–0.68, 95%CI –1.23 to –0.12, P=0.02), but there were no significant differences in levels of FPG, HbA1c and HOMA-β between the two groups (all P value > 0.05). Subgroup analysis showed that, the levels of FPG and HOMA-IR were significantly decreased in the vitamin D supplementation group in Middle Easterners and patients whose follow-up duration was less than three months. ConclusionVitamin D supplementation could improve HOMA-IR but could not improve the levels of FPG, HbA1c and HOMA-β. However, the evidence is weak to recommend vitamin D as a means of improving glycemic control, insulin resistance and β cell function in type 2 diabetes mellitus. Further larger, high quality trials are warranted.
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neuro-developmental disorders occurring in childhood, characterized by symptoms of age-inappropriate inattention, hyperactivity/impulsivity, and the prevalence is higher in boys. Although gray matter volume deficits have been frequently reported for ADHD children via structural magnetic resonance imaging, few of them had specifically focused on male patients. The present study aimed to explore the alterations of gray matter volumes in medicated-naive boys with ADHD via a relatively new voxel-based morphometry technique. According to the criteria of DSM-IV-TR, 43 medicated-naive ADHD boys and 44 age-matched healthy boys were recruited. The magnetic resonance image (MRI) scan was performed via a 3T MRI system with three-dimensional (3D) spoiled gradient recalled echo (SPGR) sequence. Voxel-based morphometry with diffeomorphic anatomical registration through exponentiated lie algebra in SPM8 was used to preprocess the 3D T1-weighted images. To identify gray matter volume differences between the ADHD and the controls, voxel-based analysis of whole brain gray matter volumes between two groups were done via two sample t-test in SPM8 with age as covariate, threshold at P＜0.001. Finally, compared to the controls, significantly reduced gray matter volumes were identified in the right orbitofrontal cortex (peak coordinates [-2,52,-25], t=4.01), and bilateral hippocampus (Left: peak coordinates [14,0,-18], t=3.61; Right: peak coordinates [-14,15,-28], t=3.64) of ADHD boys. Our results demonstrated obvious reduction of whole brain gray matter volumes in right orbitofrontal cortex and bilateral hippocampus in boys with ADHD. This suggests that the abnormalities of prefrontal-hippocam-pus circuit may be the underlying cause of the cognitive dysfunction and abnormal behavioral inhibition in medicated-naive boys with ADHD.
ObjectiveTo systematically review the efficacy of early physical rehabilitation for patients with stroke-induced hemiplegia. MethodsDatabases including PubMed, Web of Knowledge, The Cochrane Library (Issue 7, 2014), EMbase, CNKI, VIP and WanFang Data were searched to collect randomized controlled trials (RCTs) about early physical rehabilitation for patients with stroke-induced hemiplegia from inception to 1st August 2014. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, metaanalysis was performed using RevMan 5.2 software. ResultsA total of 6 RCTs were included. The results of metaanalysis showed that, after 1 month of treatment, the Fugl-Meyer scores (MD=18.02, 95%CI 6.24 to 29.80, P=0.003) and BI scores (MD=32.32, 95%CI 24.28 to 40.36, P<0.000 01) in the early physical rehabilitation group were higher than that in the conventional rehabilitation group. But after 3 months of treatment, there were no statistical differences between two groups in the proportion of patients with 0-2 MRS scores, mortality and the incidence of complications. ConclusionCurrent evidence shows that early physical rehabilitation can effectively improve the limb motor function and daily living ability in patients with stroke-induced hemiplegia. However, due to the limited quantity and quality of the include studies, more large-scale, high quality RCTs are needed to verify the above conclusion.
