Objective To evaluate the selenium nutrition level of Huaibei inhabitants and to supply valid data to Chinese Microelement Nutrition Database. Methods 513 healthy people living in Huaibei for more than 10 years were selected randomly from September 2003 to June 2004. The selenium content in hair was measured by catalytic polarographic method to delimit selenium richness region. According to the selenium content in hair,the intake of selenium from food was estimated. The investigation results were evaluated by the standard of Chinese Dietary Reference Intakes. Results The selenium content in hair was (0.390 3?0.104 5) ?g/g in Huaibei inhabitants,only 51.9% of the people reached the proper level. The average intake of selenium of Huaibei inhabitants was (31.92?9.93) ?g/d,which showed that the selenium nutrition level of Huaibei inhabitants was lower than the standard of Chinese Dietary Reference Intakes except children between 0 to 6 years old. The percent which satisfied RNI and EAR standard occupied 19.9% (102/513) and 32.9% (169/513) respectively,which were also much lower than the 50% of physiological necessary level. Conclusion The selenium intake from food in Huaibei inhabitants was scarce obviously. To increase the selenium intake properly will be a wise selection.

Objective To observe the clinical effect of tigecycline combined with cefoperazone sulbactam for the treatment of pneumonia caused by muitidrug-resistant acinetobacter baumannii pneumonia. Methods 68 patients with muitidrug-resistant acinetobacter baumannii pneumonia were randomly divided into two groups, control group and observation group, with 34 patients in each group. The control group was treated with cefoperazone sulbactam, and the observation group was treated with tigecycline combined with cefoperazone sulbactam. The level of PCT, CRP, WBC and clinical cure rates, as well as microbiological eradication and side effect, before and after treatment were collected and compared. Results After treatment, the level of PCT, WBC and CRP in two groups was decreased, and the observation group was more significant than the control group(P < 0.05). The side effect rate in two groups were 14.7% and 17.6% respectively (P > 0.05), while the clinical cure rates and microbiological eradication in observation group were significantly higher than the control group (P<0.05). Conclusion With a higher rate of clinical efficacy and a lower rate of side effect, the combination treatment with tigecycline and cefoperazone sulbactam would be a promising alternative for the treatment of muitidrug-resistant acinetobacter baumannii pneumonia infection.

Objective To evaluate the treatment effect of Lobaplatin combined with Aidi Injection on patients with advanced NSCLC, and observe the influence on the level of serum VEGF by the treatment. Methods 60 patients, with advanced NSCLC and malignant pleural effusion, were divided into two groups (observation group and control group) randomly, with 30 cases in each group. All patients were treated with thoracentesis and inserted central venous catheter for the drainage of pleural effusion. After exhaustion of pleural effusion, the control group was treated with Lobaplatin by pleural perfusion, and the observation group was treated with Aidi Injection in addition to the treatment on control group. The treatment, side effects and quality of life and the level of serum VEGF were compared. Results After treatment, it is significant that clinical effects, side effect and KPS score of living quality of the observation group was better than that of the control group (P<0.05). The level of serum VEGF was significant lower than that before treatment in both groups (P<0.05). The decrease of VEGF serum level in the observation group was significantly lower than the decrease in the control group (P <0.05). Conclusion Lobaplatin combined with Aidi Injection was one of the effective method for the treatment of NSCLS with malignant pleural effusion, and was worthy of clinical application.

Objective To investigate the diagnostic value of improved pleural biopsy combined with biomarker and cytology detection in pleural effusion of unknown origin.Methods The clinical data in 216 cases of pleural effusion were respectively analyzed including 106 cases of tuberculous pleural effusion(tuberculosis group) and 110 cases of malignant pleural effusion(malignant group).All cases were performed the improved pleural biopsy,cytology examination and detection of pleural effusion ADA,CEA and LDH,and serum CEA.The pleural biopsy diagnosis rate was performed the statistics,and pleural effusion ADA,CEA and LDH,serum CEA,and pleural effusion CEA/serum CEA were compared between the two groups.Results Among 216 cases,241 times of pleural biopsy puncture were conducted,the first time puncture success rate was 94.9 ％ (205/216).Having the diagnostic value among pathological results of pleural biopsy materials in first puncture success accounted for 58.8％ (127/216),and the overall diagnosis rate was 65.3 ％ (141/216).The incidence rate of adverse reactions was 5.8 ％ (14/241).In the tuberculosis group,no case showed cytology tumor cell positive,while the cytology tumor cell positive rate in the malignant group was 54.5％ (60/110);pleural effusion CEA and LDH,serum CEA and pleural effusion CEA / serum CEA levels and positive rates in the malignant group were significantly higher than those in the tuberculosis group,while the pleural effusion ADA level and positive rate were significantly lower than those in the tuberculosis group the difference was statistically significant(P＜0.01).Conclusion Improved pleural biopsy,pleural effusion cytology,pleural effusion biomarkers have a certain limitation in alone auxiliary diagnosis of pleural effusion.The various indicators can be combined to determine the etiology of pleural effusion in clinic for guiding treatment.

Objective To investigate the diagnosis and treatment of traumatic pancreatic injury.Method The clinical data of 35 patients with traumatic pancreatic injury treated between January 1998and July 2010 at the General Hospital of Chinese PLA were retrospectively analyzed.Results There were 9 patients with Grade Ⅰ injury,7 with Grade Ⅱ injury,7 with Grade Ⅲ,7 with Grade Ⅳ,and 5 with Grade V injury,respectively.The diagnostic rate using CT before operation was 75.8％.8 patients with mild traumatic pancreatic injury received nonoperative treatment. 27 patients underwent open operation which included 15 simple external drainage of the pancreas area,2 distal pancreatectomy,5 Roux-en-Y pancraticojejunostomy,3 duodenal diverticulisation procedure,and 2 pancreaticoduodenectomy.After operation,there were 14 patients with pancreatic leakage,9 with intraabdominal infection,and 6 with intrabdominal bleeding.There were 3 patients with Grade Ⅳ and Grade V injuries who died of multiple organ failure or uncontrolled massive intraabdominal bleeding.Conclusions It was difficult to diagnose pancreatic injury before operation.CT was a suitable method to accurately diagnose severe traumatic pancreatic injury.Most minor pancreatic injury could be treated nonoperatively or by external drainage.The appropriate operation should be selected according to the extent and degree of the injuries basing on the principle of damage control in patients with major injuries.Pancreatic fistula,intraabdominal infection and bleeding were conrmon complications after operation.Multiple organ failure and massive bleeding were the main causes for mortality.

Objective　To establish the animal model of denervation of sympathetic nerve and to explore the effects of denervation of the sympathetic nerve on liver regeneration after partial resection. Methods　The animal model of denervation of sympathetic nerve was made with 6-OHDA. A total of thirty male Wistar rats were divided equally into experimental and control group. The left and middle lobe of liver were resected with improved Higgins and Anderson's method. Meanwhile, denervation was made in the experimental group. All the rats were killed by haemospasia on the 7 th day after operation. HMI, RLR and MI were measured. The rates of DNA synthesis were detected by 3H-TdR method. Results　The concentration of NE decreased extremely on day 3 to day 14 after administration of 6-ONDA. No death happened in all the rats 7 days after liver resection. HMI, RLR, MI and 3H-TdR incorporation significantly decreased in experimental group compared with that in control (P<0.01). Conclusion　The chemical denervation of sympathetic nerve can be aroused by administration of 6-OHDA. Regeneration of the liver is inhibited by the denervation of sympathetic nerves.

Objective To investigate the feasibility, effect and mechanism of chemical bile duct embolization for chemical hepatectomy. Methods Phenol or absolute ethanol plus cyanonacrylate were employed as embolization agents. Histology, Fas and TGF-? 1 measurement were used to evaluate the result. Results Phenol plus cyanonacrylate effectively destroyed and embolized intrahepatic biliary duct, leading to complete disappearance of hepatocytes in the periphery of embolization lobe and thereby achieving the effect of chemical hepatectomy. Expression of Fas and TGF-? 1 in phenol embolism group (88.90?38.10, 185.22?70.39) and ethanol embolism group (72.39?29.51, 163.56?51.75) were higher than those in biliary duct ligated group (26.31?12.07, 74.84?40.73) ( P
