Objective To observe the symptoms,short and long term effects of body gama-knife in treatment of obstructive jaundice caused by cholangiocarcinoma.Methods 76 patients with obstructive jaundice caused by cholangiocarcinoma were treated with OUR-QGD body gamma-knife.The single therapeutic dose was 3.0-4.0 Gy,isodose curves was 50.0 ％-65.0 ％,the total treatment time was 10-12 times.The liver function,blood routine and adverse effects were monitored.Results Among 76 patients,the jaundice symptoms of 69 cases were significantly reduced,the TBIL and ALT levels were significantly lower than that before treatment (P ＜ 0.05),the ORR was 88.16 ％ (67/76),DCR was 90.79 ％ (69/76).The median TTP was 8.8 months and the median OS was 13.4 months.Conclusions Body gamma-knife treatment for obstructive jaundice caused by cholangiocarcinoma can significantly improve symptoms of patients,and improve their life quality.This treatment has less adverse effects and satisfaction short-time and long-term effects.

Objective: To establish a white noise-induced stress ulcer model in rats and to assess the changes of gastric parietal cell configuration and acid secretion under noise stress. Methods: Rats were randomly divided into 3 groups: NS 4 h,8 h and control groups. The rat NS model was induced by white noise. The pH values of gastric juice were measured by the pH/mV pH meter and the gastric ulcer index (UI) was evaluated. The stomach tissue was processed for immunofluorescence detection and the β subunit of H+, K+-ATPase was immunostained. The gastric parietal cell configuration was observed with conventional microscopy and confocal laser scanning microscope. Results: (1)The pH value of NS 4 h group (2.22±0.05) was significantly lower than that of control group (2.59±0.21, P<0.05), but higher than that of NS 8 h group (1.31±0.06, P<0.01). (2) The UI of NS 4 h group (10.5±1.29) was significantly higher than that of the control group (P<0.05), but significantly lower than that of NS 8 h group (34.36 ± 2.22, P < 0.01). (3) The reticular pattern parietal cells in NS 4 h group (55.5±3.42)/100 was significantly higher than that in control group (42.5±3.70/100, P<0.01), but lower than that in NS 8 h groups (62.0±3.46/100, P<0.05). (4) The pH was negatively related with both UI (r=-0.85, P<0.05) and the number of reticular parietal cells (r=-0.89, P<0.05). Conclusion: A white noise-induced stress ulcer model has been successfully established in rats. NS rats develop gastric mucosal lesions with increased acid secretion, which is closely related with the oxyntic function of parietal cells.

Objective - （ ） To explore the influence on the diagnosis of occupational noise induced deafness ONID using three ， Methods versions of diagnostic criteria in 2002 2007 and 2014. A total of 1 766 workers who asked for ONID diagnosis were selected as the research subjects using judgment sampling method. The results of pure tone audiometry were collected. GBZ 49-2002Diagnostic Criteria of Occupational Noise-inducedHearing Loss（ The ONID was diagnosed using hereinafter referred to as GBZ 49-2002），GBZ 49-2007Diagnostic Criteria of Occupational Noise-induced Deafness（ GBZ 49-2007） hereinafter referred to as GBZ 49-2014 Diagnostic of Occupational Noise-induced Deafness（ GBZ 49-2014）， and hereinafter referred to as and the Results - - ， - diagnostic results were compared. Compared with GBZ 49 2002 and GBZ 49 2007 diagnosis with GBZ 49 2014 had （ vs ， vs ， P ）， （ vs ， a higher rate of ONID 57.9% 66.0% 44.8% 66.0% both <0.01 and had a higher rate of mild ONID 47.3% 54.6% vs ， P ） - - 36.0% 54.6% both <0.01 . The diagnostic rate for ONID using GBZ 492014 was higher than those using GBZ 49 2002 and - （ P ）Conclusion - GBZ 49 2007 in each age groups all <0.01 . GBZ 49 2014 improved the diagnostic rate of ONID compared - - with GBZ 49 2002 and GBZ 49 2007. The reason is related to the inclusion of 4 000 Hz hearing threshold with a weight of 0.1 - as the diagnostic hearing threshold and the use of a new age and gender correction method in GBZ 49 2014.

Objective To explore the dignostic value of the candidate molecular markers in Urothelium carcinoma based on Illumina Transcriptome Sequencing. Methods Candidate genes which were screened with transcriptome sequencing were validated by using real-time fluorescent quantitative PCR in 31 pairs of tumor and normal tissues of Urothelium carcinoma patients from Affliated Hai kou Hospital Xiangya School of Medicine Central South University. Results The four candidate genes (CDH1,VEGFA,PTPRF and CLDN7) in tumor tissues were up-regulated compared with normal groups in samples of sequencing. The relative expression of VEGFA mRNA were higher than that in normal tissues. There were significant difference in two groups (P<0.05). PTPRF and CLDN7 were also up-regulated, but no significant difference was found (P > 0.05). PTPRF was closely related with the recurrence of tumor (P=0.002), and the predict sensitivity and speciality rate were 90.0%and 83.3%respectively. Conclusions CDH1 and VEGFA play important roles in the occurrence and development of bladder urothelial carcinoma, and they may be the possible biomarkers. PTPRF is expected to be a molecular reference recurrent predictor of bladder tumor.

Objective To have knowledge of the exact cause of massive osteolysis. Methods Hair of patients from Xinjiang province was collected and 14 trace elements were determined by inductively coupled plasma mass spectrometryICP-MS. Results Trace elements imbalance in the body of patients was disturbed. Chromium and zinc which are benefit to the growth of the bones were only 0.5 ?g/g and 40 ?g/g respectively that were much lower compared with the healthy persons cadmium was much higher than the limit level in healthy person. Moreover the quantity and ratio of potassium and sodium in the patients were obvious abnormal. Conclusion According to the result of the present paper may be the environmental and dietary factors play an important role in pathogenesis of this disease.

Objective:To calculate the health efficiency of government health expenditures in 1990 , 2000 and 2010 and analyze its determinants. Methods:To calculate the health efficiency of government health expenditures and analyze its determinants by using the DEA-Tobit model. Results:Health efficiency of government health expenditures has been increasing gradually;the same provinces are found to be on the productive frontier, but the provinces off the frontier are different;eastern provinces have a higher efficiency than those in the middle and western regions. Fiscal decentralization has a significant negative impact on health efficiency. Conclusion:The current Chinese fiscal decen-tralization system reform is important to improve the health efficiency of government health expenditures.
