Objective To evaluate the necessity of indwelling gastrointestinal decompression after gastrectomy. Methods Eight publications on the necessity of gastrointestinal decompression after gastrecomy were colleted, data on recovery time of gastrointestinal function and hospital stay, complications,and motality were Meta-analyzed using fixed effect model and random effect model. Results Eight randomized trails including 975 patients were qualified and included in this study. The differences in time to oral intake ( WMD =0. 61, 95% CI: 0. 17 - 1.05, P ＜ 0. 05 ) and hospital stay ( WMD = 1.20, 95% CI:0. 05 -2. 36, P ＜ 0. 05 ) between the decompression group and non-decompression group were statistically significant, but the difference in time to flatus (WMD = 0. 31,95% CI: -0. 07- 0. 69, P ＞ 0. 05 ) was not significant. There were no significant differences in complications such as nausea and vomiting ( OR = 1.43,95% CI: 0. 61 - 3.31, P ＞ 0. 05 ), pulmonary infection and atelectasis ( OR = 1.43, 95 % CI: 0. 82 - 2. 49,P＞0.05), anastomotic leakage (OR = 1.17, 95%CI: 0.54-2.49, P ＞0.05), abdominal abscess ( OR = 1.08, 95% CI: 0. 50 - 2. 34, P ＞ 0. 05 ), wound dehiscence ( OR = 1.47, 95% CI: 0. 43 - 4. 95,P ＞ 0. 05 ) between the two groups, except for fever ( OR = 1.76, 95% CI: 1.11 - 2. 78, P ＜ 0. 05 ), which was found more frequent in decompression group than in non-decompression group. Conclusions Routine gastrointestinal decompression after gastrectomy was not conductive to the recovery of gastrointestinal function, and could not reduce the incidence of postoperative complications. Postoperative GI decompression increased fever incidence rate and prolonged hospital stay.

Objective To investigate the role of oxidative stress in the epithelial-to-mesenchymal transdifferentiation (EMT) of peritoneal mesothelial cells in rat model of peritoneal fibrosis and the effect of probucol on peritoneal fibrosis. Methods The rat model of peritoneal fibrosis was induced by 4.25% high glucose peritoneal dialysis fluid (PDF). The rats were randomly divided into 4 groups:the control group, the saline group, the peritoneal fibrosis group, and the probucol group. A 4 hour peritoneal equilibration test (PET) was performed 4 weeks later. The peritoneal function and net ultrafiltration (UF) volume were determined. The level of malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) in peritoneal tissue were examined. The histology of peritoneal membrane was evaluated by light microscopy. E-cadherin and α-smooth muscle actin (α-SMA) protein expression was evaluated by immunohistochemical method and Western blot.Results The mesothelial cells were detached from peritoneal membrane in peritoneal firbosis rats. Comparing with the control rats, the thickness of visceral peritoneum, the level of MDA, and the-SMA protein expression were increased while the net ultrafiltration volume, the level of GSH-Px and E-cadherin protein expression were decreased in peritoneal firbosis rats. All these changes were reversed in the rats treated with probucol.Conclusion Oxidative stress plays an important role in transdifferentiation of peritoneal mesothelial cell in the peritoneal fibrosis rats. Probucol can improve structure and function of peritoneum, and partially reverse the EMT by reducing the oxidative stress.

Objective To screen for microRNA (miRNA) involved in fetal rat lung development.Methods Fetal lungs were collected at their 16 d,19 d and 21 d of gestational age,and were observed after HE staining.Differentially expressed miRNA (fold change＞ 1.0) were screened by miRCURYTM locked nucleic acids chip.Some differentially expressed miRNA were selected for further analysis to investigate their change trends in 16 d,19 d and 21 d of gestational age.Results (1) Under the observation after HE staining,in gestational age 16 d group,original bronchus was dendritic distributed,with thick interstitial,rare capillary and no alveolar structure existed; in gestational age 19 d group,primary alveolar was seen,interstitial became thinner,and more capillaries were found; in gestational age 21 d group,more alveolar septa were identified and pulmonary acinus cavity was extremely expanded.(2) Two hundred and two differentially expressed miRNA were found.Among them,many miRNA were firstly reported in rat fetal lung development,suchas miRNA-3560 (8.4211415,4.8889050),miRNA-126 * (7.5239524,1.5118160),miRNA-186* (0.980 325 0,0.688 447 5),miRNA-466c* (0.977 220 0,0.877 227 0),miRNA-195 (13.549 629 0,0.985 488 8),miRNA-34a (12.426 133 0,0.604 066 2) and miRNA-466b-1 *(0.993 153 1,1.732 802 3).(3)The expression of miRNA-466c * and miRNA 186 * decreased as the gestational age increased from 16 d to 21 d,while expression of miRNA-195,miRNA-3560,miRNA-466b-1 *,miRNA-126 * and miRNA-let-7b increased; miRNA-34a expression increased during 16 d to 19 d.miRNA 17-92 family expression decreased,while expression of most let-7 family members (except let-7i and let-7e) increased from 16 d to 21 d of gestational age.Conclusions These miRNA might play an important role in the physiological mechanisms of fetal lungs development.

Objective To study the effect of single chain variable fragment (ScFv) antibody to EC3-4 fragment of desmoglein (Dsg) 3 in a mouse model of pemphigus vulgaris.Methods The ScFv an- tibody to EC3-4 fragment of Dsg-3 was injected subcutaneously into neonatal BALB/c mice at different time points;the mice were then evaluated clinically,histopathologically and by direct immunoflorescence exami- nation for the development of lesions.Results When injected alone,the ScFv antibody did not induce the appearance of key clinical features of pemphigus vulgaris.The antibody also did not prevent the develop- ment of pemphigus vulgaris features induced by sera of patients with pemphigus vulgaris,regardless of the time point of injection of ScFv antibody.Conclusion The ScFv antibody to EC3-4 fragment of Dsg-3 lacks pathogenicity in neonatal BALB/c mice,and also could not inhibit the development of lesions induced by sera from patients with pemphigus vulgaris.

OBJECTIVETo summarize the clinical experience from treatment of patients with severe acute respiratory syndrome (SARS).

METHODSRetrospective analysis of seven patients with SARS in Ditan hospital treated since April 22 in 2004 was performed.

RESULTSIn the 7 patients, 2 were male, 5 were female, and the average age was (35.3 plus/minus 11.3) years. The main clinical manifestations were fever, cough, minor or serious dyspnea, nausea, signs of injury to other organs, and so on. The treatment regiments included oxygen, small dosage and short period of methylprednisolone (1 to 2 mg/kg), use of ventilator, psychological intervention, and treatment of underlying diseases, after which, all the 7 patients recovered.

CONCLUSIONRational use of methylprednisolone and timely use of ventilator were the key steps of treatment.

OBJECTIVETo investigate the expression and role of miRNA-126/miRNA-126(*) in the fetal lung development of rats.

METHODSTwelve pregnant Sprague-Dawley rats were randomly divided into 3 groups and the fetal rats were removed at 16, 19 and 21 days of gestation respectively. Hematoxylin and eosin staining was performed to observe lung morphology of fetal rats. Then microRNA (miRNA) microarray was used to study the expression patterns of miRNA-126/miRNA-126(*) in fetal lungs at the three time points. And miRNA-126(*) was selected for further study by real-time PCR.

RESULTSThere was no evident difference in the expression of miRNA-126 among the three groups, however the expression level of miRNA-126(*) increased gradually as the fetal lung developed. The real-time PCR result further showed that expression of miRNA-126(*) increased gradually with lung development, displaying significant differences among the three groups (P<0.05).

CONCLUSIONSmiRNA-126(*) may play an important role in development of the fetal lung in rats.

OBJECTIVETo explore the effects of brain-derived neurotrophic factor (BDNF) pretreatment on beta amyloid protein (Abeta) induced impairment of in vivo hippocampal long-term potentiation (LTP) in the CA1 region of rats.

METHODSThirty-six adult male SD rats were randomly divided into six groups (n = 6): control, Abeta25-35, BDNF, (0.02 microg, 0.1 microg, 0.5 microg) BDNF + Abeta25-35. A self-made hippocampal local drug delivery catheter and a parallel bound stimulating/recording electrode were used to deliver drugs/stimulation and record field excitatory post-synaptic potentials (fEPSPs) in the hippocampal CA1 region of rats. High-frequency stimulation (HFS) was used to induce in vivo LTP.

RESULTS(1) Abeta25-35 (2 nmol) injection into CA1 region of rats did not affect the baseline fEPSPs, but inhibited the HFS-induced LTP significantly (P < 0.01). (2) Hippocampal CA1 injection of BDNF (0.1 microg) alone did not affect the baseline fEPSPs and HFS-induced LTP. (3) Compared with Abeta25-35 alone group, the averaged amplitude of LTP in BDNF (0.1 microg and 0.5 microg) plus Abeta25-35 groups significantly increased at 0 min, 30 min, and 60 min after HFS (P < 0.01), indicating that pretreatment with BDNF effectively protected against the Abeta,25-35 induced depression of LTP in a dose-dependent manner.

CONCLUSIONIntrahippocampal injection of BDNF can protect against the Abeta25-35-induced LTP impairment, suggesting that the up-regulation of BDNF in the brain could maintain the normal hippocampal synaptic plasticity and may contribute to the improvement of learning and memory in Alzheimer's (AD) disease patients.

ObjectiveTo investigate the relationship between gastrointestinal dysfunction and both severity and prognosis in patients with heatstroke (HS).Methods A retrospective analysis was conducted. Clinical data from 39 patients with HS seeking for treatment in Department of Critical Care Medicine of Chinese PLA General Hospital from January 2013 to September 2014 were enrolled. The patients were divided into two groups: gastrointestinal dysfunction group and non-gastrointestinal dysfunction group. The acute physiology and chronic health evaluationⅡ(APACHEⅡ) score within 24 hours of admission and 28-day mortality were compared between two groups. In gastrointestinal dysfunction group, the gastrointestinal dysfunction score, the duration days of gastrointestinal dysfunction, the length of intensive care unit (ICU) stay, and the duration of mechanical ventilation were collected. Pearson correlation analysis was used to analyze the relationship between gastrointestinal function and the severity of the ailment as well as the prognosis.Results Among 39 patients with HS, 32 of them showed gastrointestinal dysfunction with an incidence of 82.05%. In gastrointestinal dysfunction group, the gastrointestinal dysfunction score was 2.3±0.8, the duration of gastrointestinal dysfunction was (17.3±15.2) days, the length of ICU stay was (37.8±25.0) days, and the duration of mechanical ventilation was (27.8±14.0) days. APACHEⅡ score in gastrointestinal dysfunction group was significantly higher than that of the non-gastrointestinal dysfunction group (26.30±6.00 vs. 17.40±6.00, t = 3.555,P = 0.001). The 28-day mortality in gastrointestinal dysfunction group was slightly higher than that of the non-gastrointestinal dysfunction group without statistically significant difference [43.75% (14/32) vs. 14.29% (1/7),P = 0.216]. It was shown by Pearson analysis that gastrointestinal dysfunction score was positively correlated with APACHEⅡ score (r = 0.727,P = 0.000), and the duration of gastrointestinal dysfunction was positively correlated with the length of ICU stay (r = 0.797,P = 0.000) and the duration of mechanical ventilation (r = 0.634,P = 0.000). Conclusion The results suggest that gastrointestinal function in patients with HS reflects the severity and prognosis of the ailment.
