Objective To investigate the prevalence of excessive daytime sleepiness and explore the associated factors in university teachers and staffs in Kunming.Methods Epworth sleepiness scale was used as the tool of diagnosis. We consecutively collected the data of teachers and staffs on duty in Yunnan Nationalities University,Yunnan Agricultural University,Yunnan Normal University,Kunming Medical University and Yunnan University of Finance and Economics within 8 months.Results The prevalence of excessive daytime sleepiness in university teachers and staffs was 12.45%, the prevalence of male was 16.82% and female was 7.70%, respectively. The results of Logistic regression showed that the main associated factors of excessive daytime sleepiness were male (OR=1.898),age (30 years and less was as control group,the ORs of 31-40 year group, 41-50 years group and more than 51 years group were 1.480, 2.366 and 2.719, respectively), family history of snoring (OR=3.371), consumption sedative (OR=1.815), memory failing (OR=2.044), dizzy and feeble (OR=2. 076),choking (OR=2.143),report apnea (OR=2.684),etc. Conclusions The prevalence of excessive daytime sleepiness is high in the university teachers and staffs that can partially represent the residents of Kunming city. The associated factors of excessive daytime sleepiness hint that excessive daytime sleepiness may be caused by sleep apnea/hyperpnoea syndrome in the sample population,hence the people with excessive sleepiness need further sleep monitoring .

AIM: To observe the comparison of vitrectomy combined drug therapy ( Ranibizumab injection ) and single vitrectomy for proliferatived diabetic retinopathy ( PDR ) and the influence of the curative effect and prognosis of patients.
METHODS:In this study, 112 cases (125 eyes) with PDR were selected and randomly divided into experimental group and control group ( n= 56 ) . Fifty-six cases ( 61 eyes ) in experimental group were injected by drug therapy of 0. 5mg ranibizumab and received vitrectomy;In control group, 56 cases ( 64 eyes ) were received single vitrectomy. The intraoperative and postoperative differences of clinical indicators were analyzed in two groups.
RESULTS: The average operation time, intraoperative electric coagulation hemostasis rate and iatrogenic hiatal incidence of the experimental group were lower than that of the control group:(95. 00±13. 00) min vs (133. 00±14.5) min, 11% vs 34%, 5% vs 20%, respectively (P<0. 05). The anterior chamber and vitreous body cavity hemorrhage rate within postoperative 1mo in the experimental group were lower than that of the control group:7% vs 23%, 5% vs 12%, respectively (P<0. 05). The postoperative visual acuity of experimental group was better than that of the control group:0. 375±0. 210 vs 0. 261±0. 170, respectively (P<0. 05).
CONCLUSION: Patients with PDR injected with ranibizumab in vitreous cavity before vitrectomy can effectively reduce the operation time, less intraoperative blood loss, the incidence of iatrogenic hiatus, and intraoperative and postoperative complications. The postoperative visual acuity was better than before.

Objective To evaluate the cost-effectiveness of the comprehensive control measures carrying out in schistosomia-sis endemic inner embankment of marshland and lake regions from 2006 to 2010,so as to provide the reference for further rational allocation of limited health resources and ultimately speeding up the procedure of schistosomiasis elimination. Methods With ref-erence to the requirements of the national schistosomiasis transmission control and phase goals for schistosomiasis control in Hubei Province,Jiangling County,one schistosomiasis control pilot of Hubei Province combined with the National Health and Family Planning Commission and Ministry of Agriculture,was selected for the study. A definition of the infection rates of human and do- mestic animals was used for endemic villages stratified by different layers(i.e.,the village with the infection rates of human and domestic animals ≥3% belonged to the first layer,≥ 1% belonged to the second layer;<1% belonged to the third layer). By us- ing the stratification method and cost-effectiveness analysis,the endemic villages stratified with the different layers were investi- gated and all the data of schistosomiasis endemic situation,cost and effectiveness of schistosomiasis control were collected and comprehensively analyzed from 2006 to 2010. Results In the effectiveness of schistosomiasis control,by the end of 2010, there were no first layer villages,there were 114 second layer villages,and there were 18 third layer villages in Jiangling Coun- ty. In the former first layer villages,the schistosomiasis patients decreased year by year ultimately to 0;but in the second and third layer villages,the schistosomiasis patients increased. In the fecal treatment and management,the coverage rates of harm- less sanitary latrines were 27.45% in 2009 and 48.74% in 2010 respectively in the second layer villages,whereas there were no harmless sanitary latrines in the first and third layer villages. In the 5 years,the input of comprehensive control measures was 10 266 3900 Yuan,much higher than the human and buffalo examinations and treatments,Oncomelania hupensis snail investi- gation and elimination(4 183 000 Yuan)and other labor inputs(2 239 500Yuan). In the ratio of cost-effectiveness,the annual ratio of unit cost(1% reduction of human and buffalo infection and 1 hm2 reduction of snail areas)increased yearly. In addition, the semi-logarithmic stability trend analysis of health inputs and cost showed that there was a stable balance between inputs and cost in the different layers(logarithmic values of any two layers of pair-wise comparison were <1,and in the third layer villages, the annual average logarithmic values of 5 years were <1). Whereas,in the first and second layer villages,the annual average cost was fluctuated(the costs was higher than the inputs). Conclusion The schistosomiasis situation is reduced year by year in Jiangling County from 2006 to 2010. Whereas,the main infection source(buffaloes)still exists and the present control mea- sures including fecal management should be further strengthened. In the resource allocation,in the field of health,the annual distribution of key inputs and unit-cost control also has a further space of adjustment.
