The effects of minimally invasive surgery on the blood-brain barrier (BBB) of 30 patients with cerebral hemorrhage were investigated. Difference of the BBB index and serum MBP concentration were assessed in 15 cases of conservative treatment group and 15 cases of minimally invasive surgery group. The BBB index in minimally invasive surgery group was significantly lower than in conservative treatment group (P<0.05), and the BBB index in the two treatment groups was significantly higher than in control group (P<0.01). Serum MBP concentration in minimally invasive surgery group was significantly lower than in conservative treatment group (P<0.05), and that in the two treatment groups was significantly higher than in control group (P<0.01). It was suggested the permeability of BBB in patients with cerebral hemorrhage was increased, and BBB index and serum MBP concentration in patients with cerebral hemorrhage were increased. Minimally invasive surgery can reduce the lesion of cytotoxicity to BBB and cerebral edema.

Objective To investigate the risk factors of aneurysmal subarachnoid hemorrhage (aneuryismal sub?arachnoid hemorrhage, aSAH) vasospasm (cerebral vasospasm, CVS) and provide the basis for the clinical prevention and treatment of CVS. Methods A retrospective analysis of clinical data was conducted on 255 cases aSAH patients receiving treatment between March 2012 and March 2014 in First Affiliated Hospital of Xinjiang Medical University Department of Neurosurgery, s treated. The clinical data included admission age, gender, ethnicity, history of hypertension, smoking his?tory, arterial tumor site, improved Fisher grading, admission Hunt-Hess grade, the dosage of Nimodipine, dehydrating agent, white blood cell count, blood glucose, blood lipids, blood calcium levels, platelet count. Univariate analysis and multivariate Logistic retrospective analysis were used to analyze the association between above-mentioned factors and the occurrence of CVS. Results A total of 73 cases developed CVS after aSAH and incidence rate of CVS was 28.6%. Uni?variate analysis showed that there were significant differences between patients with and without CVS in history of hyper? tension, smoking history, improved Fisher grade, admission Hunt-Hess grade, small doses of nimodipine, white blood cell count and blood glucose (P<0.05). The Logistic regression analysis showed that the history of hypertension, smoking history, improved Fisher grade, admission Hunt-Hess grade, a small dose of Nimodipine and white blood cell count were risk factors of CVS after aSAH (P<0.05). Conclusions the History of hypertension, smoking history, improved high Fish?er grade, high admission Hunt-Hess grade are independent risk factors of CVS after aSAH. A small dose of Nimodipine is a protective factor while increase in white blood cell count is a risk predictor, which should be controlled by enhancing clinical prevention.

Objective:To determine the effect of apatinib combined with Xiaoyan decoction for the treatment of non-squamous non-small cell lung cancer. Methods:Thirty-eight patients with non-squamous non-small cell lung cancer were randomly categorized into apatinib group (group A, 18 cases) and apatinib combined with Xiaoyan decoction group (group B, 20 cases). All patients did not under-go surgical treatment, radiotherapy, or chemotherapy during the study. Results:The median progression free survival (mPFS) of ad-vanced non-squamous non-small cell lung cancer patients reached up to 3 months. The mPFS, objective response rate, and disease control rate of the apatinib combined with Xiaoyan decoction group showed no significant difference and statistical significance (P>0.05). The apatinib combined with Xiaoyan decoction group was superior to the apatinib group with regard to alleviating clinical symp-toms and adverse reactions (P<0.05). Conclusion:Xiaoyan decoction combined with apatinib can improve the clinical symptoms of pa-tients and reduce the incidence of adverse reactions in the treatment of advanced non-squamous non-small cell lung cancer.

Objective To study the effects of tetramethylpyrazine(TMP) on the expression of nuclear factor-kappa B(NF-?B) induced by advanced glycation end products(AGEs) in retinal pigment epithelial(RPE).Methods The expressions of NF-?B were detected by immunohistochemical method when the RPE cells were cultured with different concentrations of AGEs in different time points.Results With the increasing of concentrations of AGEs,the expression of NF-?B in RPE was increased gradually.The expression of NF-?B in RPE was higher when the cells were cultured with AGEs for 24 h than that of other time points.With the increasing of the concentration of TMP,the expression of NF-?B in RPE was decreased gradually.Conclusion The AGEs can induce the expression of NF-?B in RPE,and the TMP can prevent the effects of AGEs in a concentration dependent manner.

Objective To evaluate the safety of anesthesia endoscopic retrograde cholangio pancreatography (ERCP) under general anesthesia.Methods From January 1st,2008 to June 30th,2016,patients underwent ERCP under general anesthesia were enrolled as anesthesia group and from January 1st,2005 to December 31st,2007,patients accepted ERCP without anesthesia were enrolled as control group.Chi-square test was performed to analyze disease composition,conditions during operation,success rate of operation and complications in these two groups.Results A total of 14 724 patients with ERCP under general anesthesia and 2 102 patients received ERCP without anesthesia were enrolled.In 14 724 patients with ERCP under general anesthesia,1 799 cases had malignant biliary and pancreatic diseases and 12 925 cases with biliary and pancreatic diseases.During the operation,transient hypoxemia occurred in 441 cases (3.00％) and relieved by increasing oxygen flow,lower anesthetic dose or lifting lower jaw.The success rate of ERCP in the anesthesia group (98.41 ％,14 490/14 724) was higher than that in the control group (97.34％,2 046/2 102),and the difference was statistically significant (x2 =11.500,P=0.001).The incidence rate of post-ERCP pancreatitis in the anesthesia group was 2.35％ (346/14 724),which was lower than that in the control group (3.85％,81/2 102),and the difference was statistically significant (x2 =16.813,P＜0.01).Conclusion ERCP under general anesthesia is safe,which could increase the success rate of operation and reduce the incidence rate of post-ERCP pancreatitis.
