Objective:To identify the vision care access in rural primary health institutions and the utilization of vision inspections among rural residents. Methods:Survey data was collected from primary health institutions ( town-ship health centers and village clinics) and households. The descriptive statistics and multivariate regression analysis were applied to analyze data. Results:The household survey data shows that 33. 2% of rural residents self-reported having poor vision, and 22. 1% of rural residents stated that they had ever used vision care (vision screening or vison examinations) . The health facilities survey data shows that 84% of township health centers and 44% of village clinics can provide vision care. The multivariate analysis shows that the vision care access in township health centers is sig-nificantly correlated with the probability of residents’ utilization of vision care, but there is no significant correlation between the provision of vision care in village clinics and its utilization. Conclusions:The vision care access is low in rural China though there is a huge demand therefore. Inadequate supply of primary vision care services in primary health institutions may result in low utilization among rural residents. It is suggested that the government further pro-mote the National Public Health Service Program and strengthen the capacity of primary health facilities to provide primary vision care. To do so, an increase in the utilization of vision care among rural residents can be expected, which would thereby reduce potential losses caused by further vision impairment.

Objective To describe the real experience of nurses from different grade hospitals during further study in the three-level hospital.And to provide the basis to make plans,improve the effect of fustther study and ensure the realization of further study aim.Methods In-depth interviews were canied out with 28 nurses by using Hidegerian phenomenological method.The acquired data were reorganized,analyzed and extracted themes.Results Different grade hospital nurses had different psychological experience such as aims,willingness,effects,obtainment and stress.Condusions Further study should be based on subjective willingness and definite goals.Hospitals should strictly select nursing teachers,give differential treatment in education,fully understand the pressure source and provide corresponding measures to reduce stress of nurses.

Objective:To explore the effect of Naoshuning on the protein expression of Matrix metalloproteinases(MMPs) in experimental injuried brain tissue of rats. Methods:Immunohistochemistry was used to determine the changes of protein expression of MMPs. Brain tissue water content,permeability and ultramicrostructure of blood-brain barrier(BBB) were also observed. Results:Compared with the sham group,the brain tissue water and EB content of injured side and the level of MMP-2 and MMP-9 protein expression in brain tissue around contusion in model group increased obviously(all P

Objective To understand the infection status and the main risk factors of soil-transmitted nematodes in children in the poverty-stricken areas of Guizhou Province and Sichuan Province,so as to provide the evidences for making suitable control strategies in these areas. Methods A total of 95 villages and 6 primary schools in 6 poor counties in the two provinces were select-ed as investigation sites according to the stratified random sampling method. Eleven preschool children aged 3-5 years in each sam-ple village and 11 school children aged 8-10 years in each sample school were chose as investigation objectives,their feces were collected and examined by Kato-Katz technique. In addition,the village doctor and cadres in each village were investigated by a standardized questionnaire to understand the deworming condition of children and the social economy and sanitary status in 2009. Then the correlation between average soil-transmitted nematode infection rate and its influencing factors was analyzed by the Tobit model. Results A total of 1 707 children from 95 villages in the two provinces were examined. In Guizhou Province,the total in-fection rate of soil-transmitted nematodes in children was 46.1%,and the infection rates of Ascaris lumbricoides,Hookworm,and Trichuris trichiura were 31.1%,4.1% and 10.8% respectively,and the corresponding rates in Sichuan Provinces were 9.8%, 3.6%,3.5%,2.7%,respectively. In the dimension of school,a total of 890 school-aged kids from 46 schools in the two provinces were examined,the infection rates of soil-transmitted nematodes,Ascaris lumbricoides,Hookworm,and Trichuris trichiura in Guizhou Province were 53.8%,32.7%,6.6% and 14.4%,respectively,and the corresponding rates in Sichuan Province were 7.3%,2.2%,2.9% and 2.2%,respectively. The results from Tobit analysis indicated that the proportion of children accepted deworming treatment and the paddy field in the cultivated area were statistically correlated to the infections of soil-transmitted nematodes and Ascaris lumbricoides(all P < 0.05). Conclusions The soil-transmitted nematode infection rates of children are still at a high level in poor areas of southwest China. In order to decrease the infection rates,besides the long-term deworming, water supply and sanitary improvement,and the health education should be strengthened,and the treatment of soil-transmitted nematodes should be covered by the New Rural Cooperative Medical System.

OBJECTIVETo evaluate the role of polymorphism in the neurogenic differentiation factor 1(Neuro D) gene in Chinese patients with type 2 diabetes mellitus.

METHODSThe genotypes of codon 45 variant (GCC-->ACC) in the Neuro D gene were determined by mismatch PCR-restriction fragment length polymorphism assay in 448 Chinese, including 124 subjects with normal glucose tolerance and 324 patients with type 2 diabetes mellitus. The diabetic patients were divided into two groups cutting off with the age of 40 at onset.

RESULTSNo homozygote of the Ala45Thr variant was found in these subjects. The frequencies of AT heterozygous type were significantly higher in early-onset type 2 diabetic group than those in the control group and in the late-onset type 2 diabetic group (chi(2)=7.85, P=0.005; chi(2)=8.81, P=0.003). The frequencies of Thr45 allele in the early-onset type 2 diabetic group were significantly different from those of the control group (13.4% vs 5.2%, chi(2)=7.15, P=0.008) and the late-onset type 2 diabetic group (13.4% vs 5.8%, chi(2)=8.13, P=0.004). The presence of Thr45 allele was shown to have an association with early-onset type 2 diabetes (OR=2.52, 95% CI: 1.42-4.49). Furthermore, the subjects carrying the variant appeared to have lower serum concentration of C-peptide in diabetic group. However, the frequencies of polymorphism genotypes of Neuro D gene showed no difference between the late-onset type 2 diabetic group and the control group.

CONCLUSIONThe genetic polymorphism in the Neuro D is associated with the development of early-onset type 2 diabetes. The presence of Thr45 allele may represent a risk factor for early-onset type 2 diabetes among Chinese.
