Objective To investigate on out the deformity in the elderly of longevous area and the characteristics of the regions in Yunnan Province. Methods According to the forth census information, using multistage sample typical survey to the 18 counties (cities) with centenarians over 1/100 000. The deformity types of people aged 60 and over and the deformity rate of various age groups and its distribution were investigated. Results Among the 6 477 people aged 60 and over investigated, a total of 1 928 people were in deformity, the deformity rate was 29 8%. The elder the people, the higher the deformity rate was. The highest deformity rate was in Kunming and Chuxiong prefectures. The audition deformity was highest among all types of deformity in elder people. The occurrence of fracture was highest in Miao Nation in Honghe prefecture, reaching 18.1%. About 14 % of the centenarian people sufferred from dementia. Conclusions Effective control in blood pressure and osteoporosis are important method to protect the elder people and to promote the level of quality of life of the elderly.

Purpose To study the clinic-pathologic features, differential diagnosis and prognosis of lymphoepithelioma-like carcinoma of cervix. Methods Eight cases of lymphoepithelioma-like carcinoma of cervix were retrieved from our institution. HE staining, im-munohistochemistry and in situ hybridization were perform on those cases. Results Of the 8 cases of lymphoepithelioma-like carcino-ma,the median age was 44 years old ( ranged from 29-67 years) and all of the clinical stage belonged toⅠB. Grossly, 5 cases presen-ted a cauliflower-like appearance, 1 case grew as a polyp protrusion, and the other 2 cases showed a non-specified thicken change of cervix. Histologically, the tumors were composed of undifferentiated large cells, either loosely or closely-packed, with the nested and trabecular growth pattern. The tumor cells were generally oval or polygonal in shape, while the demarcation between the cells was indis-tinct and form the syncytial appearance. The nuclei were vesicular and had one or more prominent nucleoli. There were abundant infil-trates of lymphocyte and plasma cells among the tumor nests. The tumor cells showed positive expression of CK in 100% of cases, p63 in 37. 5% of cases, p16 in 62. 5% of cases, CK5/6 in 75% of cases, Ki-67 in 10% ~30% of cases. The stromal lymphocytes mainly expressed CD3 and CD8. EBER was negative in the entire tumor cells while was weakly positive in the stromal lymphocytes in one case. The follow-up data, which terminated at June 2013, demonstrate 7 cases were alive and 1 case died of the disease. Conclusions Lymphoepithelioma-like carcinoma occurred of cervix is rare. They have distinctive morphologic features and overall favorable prog-nosis. The accurate diagnosis is dependant on the combination of the histologic and immunohistochemical examination.

Objective To understand the blood pressure level of the aged in longevous area of Yunnan Province. Methods According to the forth census information,typical multistaged sample-survey was used for 15 counties (cities) with centenarians over 1/100 000 and the 3 counties (cities) with centenarians under 1/100 000. The blood pressure of people aged 60 and over were measured and the investigation questionnaire was filled in. Results The overall level of the blood pressure was systolic pressure (130.8?24.6) mm Hg and diastolic pressure (81.7?14.6) mm Hg. The systolic pressure increased in slow slope with the age growing, ranged 126.2-137.6 mm Hg, and higher in male than in female. The diastolic pressure was not affected by age growing. The difference of blood pressure in nationality was mainly affected by the latitude and the elevation. Conclusions With the age increasing, the blood pressure level of the aged people gradually increases.

ObjectiveThe efficacy and safety of nitrous oxide-sedated transnasal gastroscopy for high-risk patients of intravenous anesthesia were evaluated. MethodsA total of 157 patients were randomly assigned to the nitrous oxide group ( n =80) and the oxygen group ( n =77). Heart rate, blood oxygen saturation, blood pressure and electrocardiogram were monitored. Complications in both groups were recorded.Satisfaction degrees of patients and endoscopy physicians were evaluated with a questionnaire and visual analog scale (VAS) score. The questionnaire questions for physicians included the procedure evaluation ( steady, ok, unsteady). Patients' questionnaire questions included discomfort (light, moderate, severe), the patients' tolerance ( fine, moderate, weak) and the patients' willingness to undergo a second procedure. Statistical analysis was performed between the two groups. ResultsSix of the toal 157 patients were removed because of the operation failure (difficulty in access to nasal cavity in 5 patients and nose bleeding in one patient), 151 patients underwent the transnasal gastroscopy successfully and completed the questionnaires. In experimental group, there were 37 males and 41 females (mean age was 67.7 years, ranging 16-88 years, 7 patients were grade 1 of ASA, 61 were grade 2, and 11 were grade 3). In the control group, there were 36 males and 37 females (mean age was 67.9 years, ranging 17-86 years, 6 patients were grade 1 of ASA, 57 were grade 2, and 9 were grade 3). There was no differences in sex, average age and ASA grade between the two groups (P ＞ 0. 05 ). There was no difference in the mean operation time between the two groups, either (200. 1 s vs 200. 3 s) ( P ＞ 0. 05 ). There were no significant differences between the two groups in changes of blood oxygen saturation, blood pressure, electrocardiogram and complication rates ( P ＞ 0. 05 ).Both physicians' and patients' positive evaluations of the experimental group were more than that of the control (P ＜ 0. 05 ), while physicians' and patients' negative evaluations of the experimental group were less than the control (P ＜0. 05). VAS of physicians' satisfaction in the experimental group was higher than that of the control group (84 vs 70, t =14. 67, P ＜ 0. 05), and VAS of patients' satisfaction in the experimental group was superior to the control group (82 vs 71, t =11.56, P ＜ 0. 05). The number of patients wiring to undergo a second procedure in the experimental group was higher than that of the control (89. 7％ vs 69. 9％, P ＜ 0. 05). ConclusionNitrous oxide-sedated transnasal endoscopy is an effective and safe procedure for high risk patients of intravenous anesthesia.
