Objective To clarify the role of hypothalamic IL-6 in gastric mucosal blood flow, gastric juice pH value and gastric mucosal injury. Method Model of gastric stress ulcer was established by fluid percussion to make craniocerebral trauma. Twenty male SD rats fed for one week in the experiment room were randomly(random number) divided into control group, one hour group, six hours group and 12 hours group after injury. The levels and distribution of IL-6 in hypothalamus were detected by using immunohistochemistry and Western blot. Simultaneously, gastric pH value, gastric mucosal blood flow and gastric mucosal injury index of rats in each group were measured, and the histology of gastric mucosa was observed. Results IL-6 immunoreactive cells were widely distributed in neuronal cells of hypothalamus of the stressed rats especially in the para-ventricular nucleus (PVN).One hour after injury, the pH value rapidly declined, and the lowest point appeared 6 hours later. One hour after injury, the injury of gastric mucosa was found, and the injury became worse and worse as time got longer and longer. The ulcer index (UI) was increased. One hour after injury, there was a brief increase in blood flow to the peak in gastric mucosa, and then the blood flow declined until 6 hours elapsed and got stable. The experiment prompted the gastric stress ulcer appeared. Conclusions In the SD rats with gastric stress ulcer induced by craniocerebral injury incurred by hydraulic percussion, the hypothalamic IL-6 may activate neuronendocrine metabolism mediated through the activation of PVN, inducing gastric mucosal injury.

Objective To compare the impact on the results tested with arterial blood gas analysis and peripheral blood with glucose meter for critical patients in ICU in different temperature states. Methods The samples of venous biochemical test, blood arterial blood gas analysis and peripheral blood of 196 cases of critical patients in ICU were collected synchronously, and measure the D-value, correlation and bias adjustment factor of glucose blood tested with a synchronous fasting blood glucose test and venous/biochemical analyzer in different temperature states and different blood glucose groups, and the results of blood glucose test were analyzed. Results In normal temperature state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 3.31%(5/151), while the pairwise comparison showed there was both statistical signifcance between hypoglycemia group and target group (χ2=38.469), hyperglycemia group and target group (χ2=15.504) when choosing a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). In high temperatures state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 0. There was both statistical significance between hypoglycemia group and target group (χ2=18.187), hypoglycemia group and hyperglycemia group (χ2=12.857) when choose a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). Conclusions In high temperatures state, a synchronous fasting blood glucose test can not reflect the true value of blood glucose for critical patients.

Objective To investigate the antibiotic resistance of extended-spectrum-β-1actamases (ESBLs)-producing Escherichia coli (E.coli) and Klebsiella pneumoniae (K.pneumoniae) isolates and the risk factors of bloodstream infections caused by these strains.Methods Clinical data of 131 patients with E.coli or K.pneumoniae-induced bloodstream infections admitted in the Second Affiliated Hospital of Zhejiang Chinese Medical University during September 2009 and June 2014 were retrospectively analyzed.Species identification and antimicrobial susceptibility test were performed by Vitek 2 system,and ESBLs production was tested by standard disk diffusion method.Logistic regression analysis was performed to identify the risk factors of bloodstream infections induced by ESBLs-producing strains.Results Among 131 patients,65 were infected with ESBLs-producing strains,and 66 were infected with non-ESBLs-producing strains.The resistance rates of ESBLs-producing strains were above 50％ for penicillin,aztreonam and third/fourth generation cephalosporins,which were significantly higher than those of non-ESBLs producing strains.The resistance rates of ESBLs-producing E.coli and K.pneumoniae to carbapenems and piperacillin/tazobactam were 0-2.0％,2.3％ and 0-14.3％,26.7％,respectively.The univariate analysis revealed that patients with exposure to cephalosporins in recent 3 months (x2 =18.322,P ＜ 0.01),prior infection with ESBLs-producing strains (x2=14.610,P＜0.01),indwelling catheter in recent 3 months (x2 =13.016,P ＜ 0.01),history of hospitalization in recent 3 months (x2 =11.269,P ＜ 0.01),exposure to quinolones in recent 3 months (x2 =10.638,P ＜ 0.01),nosocomial infection (x2 =8.205,P ＜ 0.01),history of indwelling deep venous catheter or percutaneous central catheter in recent 3 months (x2 =4.817,P ＜ 0.05) and exposure to glucocorticoid hormone in recent 3 months (x2 =4.265,P ＜ 0.05) were associated with infection of ESBLs-producing strains.Multivariate Logistic regression analysis revealed that exposure to quinolones in recent 3 months (OR =6.851,P ＜ 0.01),prior infection with ESBLs-producing strains (OR =6.344,P ＜ 0.01),exposure to cephalosporins in recent 3 months (OR =3.719,P ＜ 0.01),and indwelling catheter in recent 3 months (OR =3.180,P ＜ 0.05) were independent risk factors for ESBLs-producing E.coli or K.pneumoniae infection.Conclusions ESBLs-producing E.coli or K.pneumoniae isolates are highly resistant to most antibiotics,and multidrug-resistance is common.Carbapenems were still the most effective antibiotics against ESBLs-producing E.coli or K.pneumoniae infection.Rational use of cephalosporins and quinolones,strictly following aseptic technique in operation,strict use of indications for indwelling catheterization,and completely eradicating ESBLs-producing strains in previous infections may be helpful in reducing bloodstream infections by ESBLs-producing E.coli or K.pneumoniae.

Background and purpose:Gestational trophoblastic neoplasm (GTN) is a spectrum of disease arising from trophoblastic cells, and the majority of patients with GTN have favorable outcome because of the sensi-tivity to chemotherapy. While the cure rate for high-risk patients is still 70% to 80% as a result of drug resistance and disease recurrence. This study aimed to evaluate the clinical characteristics and outcome of patients with high-risk GTN.Methods:The clinical records of patients with high-risk GTN treated in Obstetrics and Gynecology Hospital of Fudan University from Jan. 2003 to Jan. 2013 were analyzed and reviewed retrospectively from the aspect of different treatment.Results:Fifty-one patients with high-risk GTN were admitted to this hospital. Among 51 high-risk GTN patients, 46 patients were evaluated retrospectively and 5 patients were excluded for incomplete treatments. Of the 46 patients with high-risk GTN, 27 patients were treated by chemotherapy alone, 19 patients received chemotherapy and adjuvant surgical therapy. Forty-four patients received EMA-CO (VP-16+Act-D+MTX/VCR+CTX) as a ifrst-line chemotherapy, 81.82% (36/44) had complete remission and 8 patients developed resistance to EMA-CO. EMA-EP (VP-16+Act-D+MTX/VP-16+cisplatin) was used as second-line chemotherapy for the 8 patients resistant to EMA-CO, 6 patients (2 underwent adjuvant surgical therapy) achieved remission and 2 patients died as a result of drug-resistance and disease progression. For the remaining 2 patients, one was treated by 5-FU+KSM and pulmonary resection, and the other was treated by MTX for misdiagnosis as ectopic pregnancy and then converted to EMA-CO for the pathological diagnosis of choriocarcinoma after surgery. Both of them achieved complete remission. Ultimately, 95.65% (44/46)patients achieved complete remission. Among the 19 patients who underwent adjuvant surgical therapy, 94.70% (18/19) patients achieved complete remission after chemotherapy and adjuvant surgery, and the remaining one patient died of disease progression.Conclusion:Standard combination chemotherapy is crucial in the treatment of high-risk GTN. The role of adjuvant surgery in the management of high-risk GTN should not be underestimated.
