Cocaine is usually used in clinical local anesthesia. However, because of its excitatory effect, it is also abused by some people, and thus results in the onset of disease. Since the first cocaine-related stroke was reported in 1977, many researchers have gradually realized that cocaine abuse causes many cerebrovascular diseases; its exact pathophysiological mechanism remains unknown and it may be involved in a variety of mechanisms.

There is a close relationship between high trans fatty acids intake and occurrence of metabolic syndrome. Trans fatty acids intake may lead to metabolic disorders. It affects lipid level, induces visceral obesity and insulin resistance, triggers systemic inflammation, and significantly increases cardiometabolic risks. If the chain of trans fatty acids-metabolic syndrome-cardiovascular disease is understood, a new effective way to prevent metabolic syndrome and cardiovascular events may be provided.

Objective:To retrospectively evaluate the prognostic risk factors of patients with gallbladder carcinoma and the effect of normal prognostic nutrition index (PNI) on the survival. Methods:We retrospectively analyzed 63 patients with gallbladder carcino-ma treated in our hospital between January 2008 and December 2012. The independent prognostic factors of the patients were calculat-ed by the Cox proportional hazards model. The benefit of normal PNI status on the prognosis was further explored in the patients using survival analysis. Results:Lymph node metastasis, PNI≤50, squamous carcinoma, liver invasion and choledoch invasion were the risk factors of overall survival (OS) in the univariate analysis, while only lymph node metastasis (HR=4.495, 95%CI 2.380~8.488, P<0.001) and PNI(HR=0.195, 95%CI 0.098~0.389, P<0.001) were the dependent influential factors of the prognosis and OS in the multi-variate analysis. The effect of PNI on OS was even more statistically significant different in the younger patients (≤65y) than in the el-der (>65y) (younger group:P=0.011;elder group:P=0.078). Conclusion:The gallbladder carcinoma patients with normal PNI status (>50) have better OS compared to the patients with PNI≤50, with statistical differences between the two. And it is more significant in the patients of the younger group (≤65y), comparing with the elder group. PNI could be taken as a potential prognostic evaluation factor for the gallbladder carcinoma patients and can provide a more comprehensive evaluation of patients' conditions to clinician.

OBJECTIVE: To investigate the role of TREM-1 in tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) secretion from lipopolysaccharide-induced mice macrophage cell lines RAW264.7. METHODS: Designing and synthesizing small interfering RNA (siRNA) with high intangerference ratio, then constructing pLKO1.1-puro-TREM-1 The mice macrophage cell lines RAW264.7 were divided into four groups: control group (control); lipopolysaccharide group (LPS); empty plasmid group (pLKO1.1) - just transfected with pLKO1.1; interference group (siRNA) - transfected with pLKO1.1-puro-TREM1.24 h after stimulation with LPS, real-time PCR was used to detect the mRNA levels of TREM-1, TNF-α and IL-1β respectively. The concentrations of TNF-α and IL-1β were assayed by ELISA. RESULTS: In siRNA group, the mRNA levels of TREM-1, TNF-α and IL-1β were decreased significantly (P<0.01): moreover, the concentrations of TNF-α and IL-1β were lower than other groups significantly (P<0.01). CONCLUSION: Small interfering RNA may reduce TNF-α, IL-1β secretion in LPS-induced macrophage 264.7 through inhibiting the expression of TREM-1 gene.

Bdellovibrio bacteria BDF-H16 was isolated from the gut of Carassius auratus gibelio with Aeromonas sobria.Its shape was ob- served by light microscopy,phase-contrast microscopy,electron microscopy and some of its biological characteristics were also studied.It was demonstrated that BDF-H16 was an gram-negative bacterium and had a bacilliform or arc bacilliform shape with a flagellum at one end.Its size was mostly 0.2?m～0.5?m?0.8?m～1.2?m.It had a wide prey area and could lyse all tested gram-negative bacteria and some gram-positive bacteria.The best lysis conditions to Escherichia coli were 6.75?10~9 cfu/mL of prey bacteria concentration,pH7.0～7.5,28℃.It could grow in the solid culture added 0.85%～5.00% NaCl and was inhibited by enrofloxacin and norfloxacin.

Objective To investigate the protective effect of pinacidil on the intestinal mucosa of scalded rats and the mechanism. Methods A total of 24 healthy SD rats were randomly divided into normal control group, burn group, and pinacidil treated group. Rats in burn group and pinacidil treated group were inflicted with 30% TBSA Ⅲ degree burn and resuscitated intraperitoneally with Ringer's solution immediately after burn. Pinacidil was injected intraperitoneally into rats in pinacidil treated group at the dose of 2 mg/kg. Mitochondrial respiratory function intestinal mucosa and levels of reactive oxygen species (ROS), maleic dialdehyde (MDA), and superoxide dismutase (SOD) in plasma were determined at 6 h after burn. Results Mitochondrial respiratory function control rate (RCR), ST3, and SOD levels in pinacidil treated group were evidently higher than those in the burn group. However, ST4, MDA, and ROS levels in pinacidil treated group were significantly lower than those in the burn group, but ST4 was not significantly different from that in the normal control. Conclusion Pinacidil can attenuate the damage of intestinal mucosa in scalded rats.

Objective To investigate effects of ginkgo biloba extract(GBE) and tanshinoneⅡ A preventative administration against cerebral ischemia and reperfusion injury in gerbils.Methods Cerebral iscthemia and reperfu- sion injury were made by 10 minutes'occlusion of bilateral carotid arteries followed by 24 hours' reperfusion in ger- bils.GBE,tanshinone Ⅱ A,nimodipine or GBE plus tanshinone Ⅱ A were administrated intragastrically 3 days prior to and at the day of ischemia and reperfusion.Effects of experimental agents on mortality,stroke index,brain body index,water content in brain hemisphere,level of SOD activity and MDA in cerebral tissue were measured,and pathological changes of cortex and hippoearnpal CA1 sector were observed.Results GBE 48 mg/kg and tanshinone Ⅱ A 25mg/kg preventive administration could significantly reduce the stroke index,brain body index,and water in brain hemisphere,together with a reduced mortality of cerebral ischemia and reperfusion injuried gerbils.The two a- gents could also significantly improve the activity of SOD,reduce the level of MDA in cerebral tissue and the injury in cortex and hippocampal CA1 sector.Moreover,combined treatment of these two agents demonstrated more signifi- cant effects.Conclusion GBE,tanshinone Ⅱ A and combined therapy of these two agents may protect cerebral func- tion from ischemia and reperfusion injury through reducing the cerebral edema and attenuating the injury of oxygen free radicals.

To study the clinical characteristics and surgical treatment of congenital scoliosis with diastematomyelia, four patients were found to have scoliosis with diastematomyelia by CT and MRI.The first step of surgery was to excise the osteal compartion in spinal cord, the second step was the posterior scoliosis correction and fusion after two weeks. All the patients had successful surgery. The body height of the patients increased 4 75cm and the Cobb angle deceased 43? in average. No complication was found in the nervous system. This method is very effective, and is worth popularizing its application.
