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.

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 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.

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.

Objective: To observe the relationship between homocysteine(Hcy)and spatial cognitive ability and to evaluate whether vitamin B12 supplementation could protect spatial cognitive ability in rats. Methods: The rats were randomized into three groups. The experimental group was given methionine subcutaneously. The intervention group was given methionine and vitamin B12 subcutaneously. The control group received isometric normal saline. After being raised for 8 weeks, all rats were examined for plasma Hcy and serum vitamin B12 and scores of Y-maze test. The brain tissues of hippocampus were checked immunohistochemically for acetylcholinesterase (AChE). Results: The experimental group developed hyperhomocysteinemia and descreased spatial cognitive ability significantly (P0.05). Conclusion: Homocysteine can impair the spatial cognitive ability in rats and vitamin B12 is effective in lowering Hcy level and protect the spatial cognitive ability of rats.

Objective To observe the effect of indwelling transanal tube on prevention of anastomotic leakage after congenital megacolon radical correction. Methods One hundred and three children who had underwent congenital megacolon radical correction were divided into indwelling group (53 cases) and no indwelling group (50 cases) according to the operation method, and the operation condition and incidence of complications was compared between 2 groups. Results There were no statistical differences in operation time, amount of bleeding during operation and incidence of other complications (pelvic infection and disruption of wound) (P>0.05). The incidence of anastomotic leakage in indwelling group was significantly lower than that in no indwelling group: 0 vs. 12.0% (6/50), and there was statistical difference (P<0.05). Conclusions Indwelling transanal tube for drainage and decompression is effective in preventing the anastomotic leakage after congenital megacolon radical correction, and it has high effectivity and safety.

The pathogenesis of allergic rhinitis(AR)is extremely complex.In recent years,a variety of allergens and other complexes have been developed to induce a series of signal transduction mechanisms by activating mast cells.Intracellular media release(mast cells,MCs)play an important role in the pathogenesis of AR.In this paper,we reviewed the progress of mast cells in the pathogenesis of allergic rhinitis in recent years in order to further understand its role in the pathogenesis of allergic rhinitis and provide new ideas on the therapeutic target for allergic rhinitis.
