Reduced Firing of Nucleus Accumbens Parvalbumin Interneurons Impairs Risk Avoidance in DISC1 Transgenic Mice / 神经科学通报·英文版

A strong animal survival instinct is to approach objects and situations that are of benefit and to avoid risk. In humans, a large proportion of mental disorders are accompanied by impairments in risk avoidance. One of the most important genes involved in mental disorders is disrupted-in-schizophrenia-1 (DISC1), and animal models in which this gene has some level of dysfunction show emotion-related impairments. However, it is not known whether DISC1 mouse models have an impairment in avoiding potential risks. In the present study, we used DISC1-N terminal truncation (DISC1-N

A systematic review of intervention effects of mindfulness-based stress reduction on irritable bowel syndrome / 中国心理卫生杂志

Objective:To investigate the effects of mindfulness based stress reduction on irritable bowel syndrome.Methods:PubMed,EMBASE,Cochrane Library,Web of Science,CNKI,Wanfang Data was searched and randomized clinical trials of MBSR treatment in irritable bowel disease were involved.At last two reviewers extracted the data independently.According to Cochrane Handbook5.1.0 handbook,a quality assessment was made.All the data would be analyzed with meta-analysis by the software of Stata.Results:Totally 5 randomized controlled trials were eligible,including 461 participants.Meta-analysis showed that MBSR would be better therapy method to improve the symptom severity of irritable bowel syndrome in 3 months,[SMD =-0.60,95％ CI:-0.86 ～-0.34,P ＜0.01],and the pain index at the 3 months and 6 months was relieved compared to the baseline [SMD =-1.11,95％ CI:-1.45 ～-0.76,P ＜ 0.01,SMD =-0.14,95％ CI:-0.43 ～ 0.14,P ＜ 0.05].Conclusion:Mindfulness based stress reduction therapy could be a adjunctive therapy method in treatment of irritable bowel syndrome.

High-flow nasal cannulae oxygen in patients with respiratory failure: a Meta-analysis / 中华危重病急救医学

Objective To systematically evaluate the efficacy of high-flow nasal cannulae oxygen (HFNC) in patients with respiratory failure.Methods Computerized PubMed, Embase, Web of Science, the Cochrane Library, CNKI, CBM, VIP, Wanfang Database up to March 31st, 2017, all published available randomized controlled trials (RCTs) or cohort studies about HFNC therapy for patients with respiratory failure were searched. The control group was treated with face mask oxygen therapy (FM) or non-invasive positive pressure ventilation (NIPPV), while the experimental group was treated with HFNC. The main outcomemeasurements included endotracheal intubation rate, patient comfort, and the secondary outcome was in-hospital mortality. The quality of the literature was completed by two professionally trained evidence-based medical students, and meta-analysis was performed on quality-compliant literature. Funnel plot was used to analyze the publication bias.Results A total of 17 articles were enrolled including 15 RCTs and 2 cohort studies. There were 3909 patients enrolled, 1907 patients in HFNC group, and 2002 in control group (1068 patients with FM, and 934 with NIPPV). Meta-analysis showed that HFNC had a significant advantage over FM in reducing the tracheal intubation rate of patients with respiratory failure [odds ratio (OR) = 0.51, 95% confidence interval (95%CI) = 0.29-0.89,P = 0.02], but there was no significant difference as compared with that of NIPPV (OR = 0.80, 95%CI = 0.54-1.17,P = 0.25). It was shown by pooled analysis of two subgroups that compared with FM/NIPPV, HFNC had a significant advantage in reducing tracheal intubation rate in patients with respiratory failure (pooledOR = 0.66, 95%CI = 0.47-0.94, P = 0.02). Compared with FM, patients with respiratory failure were more likely to receive HFNC for comfort [standardized mean difference (SMD) = -0.41, 95%CI = -0.56 to -0.26,P < 0.00001]. There was no significant difference in hospital mortality between HFNC and FM (OR = 0.82, 95%CI = 0.55-1.24,P = 0.35) or NIPPV (OR = 0.66, 95%CI = 0.37-1.17, P = 0.16). The results of pooled analysis of two subgroups were still unchanged (pooledOR = 0.75, 95%CI = 0.54-1.05, P = 0.09). It was shown by the funnel analysis that there was a bias in the study of tracheal intubation rate in the literature, while the bias of patient comfort and hospital mortality was low.Conclusions Compared with FM, HFNC could reduce the rate of tracheal intubation in patients with respiratory failure, but no difference was found as compared with NIPPV. Compared with FM, HFNC made patients more comfortable, and it was easier to be accepted and tolerated. However, there was no difference in hospital mortality among FM, NIPPV, and HFNC.

Application of uterine incision suture in multiple segment shrinkage in cesarean section / 中国基层医药

Objective To explore the application value of uterine incision suture in multiple segment shrinkage in cesarean section.Methods 85 pregnants with uterine scar who taken cesarean section were selected.In the single month,the pregnants were included in the observation group(43 cases):after pruning scars,uterine lower segment weak muscle tissue by wrinkling suture to reinforce the thickness of the lower segment again from both sides of the suture,intermediate knotted suture the uterine incision.In the bimonth,the pregnants were included in the control group(42 cases):after pruning scars by conventional suture incision of lower uterine segment.The duration of vaginal bleeding time after operation ,postoperative 42 days ,3 months ultrasonography of uterine incision healing were observed.Results The postoperative vaginal bleeding volume of the observation group was less than that of the control group[(480.55 ±53.75)mL vs.(550.14 ±50.45)mL],the bleeding time was less than that of the control group[(21.31 ±6.78)d vs.(30.45 ±5.16)d],the differences were statistically significant(t =3.65,2.28,all P <0.05).March B -ultrasonography uterine incision after surgery,the good healing rate of the observation group was 95.35%,which of the control group was 78.57%,the difference was statistically significant(χ2 =4.35,P <0.05). Conclusion Incision under section shrinkage joint is conducive to the incision structure and muscle layer mechanical recovery and can reduce the amount of vaginal bleeding and time and defect healing of incision morphology.

Development of a diagnosis model for active pulmonary tuberculosis using mass spectrometry and pro-tein chip / 中华微生物学和免疫学杂志

Objective To develop a diagnosis model for active pulmonary tuberculosis. Methods The proteomic fingerprinting of 264 sera from active tuberculosis patients and controls were analyzed using the surface-enhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF-MS) and protein-chip technology. The peaks were detected and filtrated by Ciphergen PrnteinChip(R) Software (version 3.1.1). Using the Biomarker Pattern 5.0 software, a diagnostic model was developed for diagnosis of active tuberculosis. Re-sults Fifty protein peaks were significantly different between the patients with active pulmonary tuberculosis and the controls with overlapping clinical features (P<0.01). Five protein peaks at 4360, 3311, 8160, 5723, 15173 m/z were chosen for the system classifier and the development of diagnosis model 1. The model differenti-ated the patients with active pulmonary tuberculosis from the controls with a sensitivity of 83.0%, and a speci-ficity of 89.6%. The diagnostic accuracy was up to 86.4%. Three protein peaks at 5643, 4486, 4360 m/z were chosen for the system classifier and the development of diagnosis model 2. The model differentiated the pa-tients with active pulmonary tuberculosis from the controls with a sensitivity of 96.9%, and a specificity of 97.8%. The diagnostic accuracy was up to 97.3%. Conclusion It might be a new diagnostic test for the de-tection of sera from the patients with active pulmonary tuberculosis using SELDI-TOF-MS and protein chip.
