In order to study the susceptibility of murine vaginal mucosa to Candida albicans under different conditions, vaginal lavage fluid and vaginal tissue of mice were observed and compared between murine models with normal immune system (estrogen-treated mice) and immunosuppressed murine model, and between primary infection model of vaginal candidiasis and secondary infection one. The average level of colony forming unit (CFU) from the immuosuppressed group was higher than that from estrogen-treated group at each time point and the peak time was delayed. The differences between the two groups were statistically significant (P < 0.05) from the fourth day after inoculation. A significant difference existed in the average level of CFU between the control group and the estrogen-treated group (P < 0.05), and between the control group and the immuosuppressed group (P < 0.01). It was concluded that the vaginal mucosa from the immunosuppressed mice is more susceptible to Candida albicans and no difference is found in susceptibility between mice with primary infection and secondary infection.

Objective At present,there is still a lack of effective means for the treatment of diabetic cystopathy,and to find natural antioxidants for this purpose has become a hot spot in research. This study is to investigate the protective effect of inosine on the bladder of diabetic rats and its antioxidative stress mechanisms. Methods A total of 60 adult male Sprague-Dawley rats were ran-domly divided into three groups of equal number:normal control,diabetes mellitus(DM) model control,and inosine intervention. The DM model was made by intraperitoneal injection of streptozotocin at 60 mg/kg. The DM model controls were injected with saline while the model rats in the intervention group with inosine, all at 75 mg/kg, ip,bid. After 4 and 8 weeks of treatment, the bladder tissues were collected from the rats for examination of the structural changes by HE staining,determination of the expressions of c-kit and nerve growth factor (NGF) by immunofluorescence assay, and observation of the ultrastructure of the bladder tissue under the electron microscope,de-tection of the cell apoptosis by TUNEL,and measurement of the con-tents of malondialdehyde (MDA),superoxide dismutase (SOD),and glutathione (GSH). Results HE staining indicated signifi-cant mucosal hyperplasia, disordered arrangement, loose structure, fracture, expanded intervals and collagen fiber filling of muscle bundles,muscular atrophy,lymphocytes infiltration,vascular hyperplasia and congestion,and few muscle bundles,while electron mi-croscopy manifested disordered arrangement, interrupted connection, mitochondrial vacuolation in muscular and interstitial cells, shrinkage of nuclear membrane,disappearance of nucleoli,and irregular chromatin margination and condensation in the bladder tissues of the DM rat models. Immunofluorescence assay showed that the signals of c-kit and NGF were reduced in the DM models as compared with those in the normal controls. After 4 and 8 weeks of intervention,the cell apoptosis rate was significantly higher in the DM model control ([1.68±3.04]% and [10.51±0.90]%) and inosine-treated rats ([7.00±1.72]% and [7.24±1.66]%) than in the normal controls ([4.65±3.04]% and[5.48±2.00]%),but remarkably lower in the inosine-treated than in the DM model controls(P<0.01). The contents of SOD and GSH were increased(P<0.05) while that of MDA decreased markedly in the DM models(P<0.05),but the former decreased (P<0.05) while the latter increased significantly in the inosine intervention group as compared with the DM model control group (P<0.05). At 8 weeks,the contents of SOD and GSH were remarkably lower in the DM model than in the normal con-trols (P<0.01),while that of MDA markedly higher than in both the normal control and inosine intervention groups (P<0.01). The wet weight of the bladder was significantly increased in the DM model and inosine intervention groups in comparison with that of the nor-mal controls(P<0.01). Conclusion Oxidative stress plays an important role in the development and progression of diabetic cystopa-thy. Inosine can protect the bladder structure and function of the DM rat by reducing oxidative stress and injury to the bladder tissue.

OBJECTIVETo investigate the effects of sleep deprivation on intelligence development in primary school students.

METHODSBetween June 2009 and April 2010, 316 grade 5 students aged 10-11 years were selected from four primary schools in four administrative districts of Changsha, China by stratified random sampling. The intelligence characteristics of children with varying degrees of sleep deprivation were investigated using the Chinese Wechsler Intelligence Scale for Children.

RESULTSA total of 286 valid questionnaires were received, with a response rate of 90.5%. The survey was comprised of a sleep deprivation group (sleep time <8 hours per night; n=180) and a control group (sleep time ≥8 hours per night; n=106). The sleep deprivation group had significantly lower subtest scores, verbal intelligence quotient (IQ) (VIQ), performance IQ (PIQ) and full scale IQ (P<0.05) and significantly lower verbal comprehension factor score and memory/attention factor score compared with the control group (P<0.05). Compared with the control group, the moderate sleep deprivation subgroup had significantly decreased VIQ and full scale IQ as well as verbal comprehension factor score and memory/attention factor score (P<0.05), and the severe sleep deprivation subgroup showed decreases in all scores (P<0.05). The sleep deprivation group and moderate and severe sleep deprivation subgroups had significantly higher proportions of children with VIQ-PIQ imbalance than the control group.

CONCLUSIONSSleep deprivation adversely affects intelligence development, especially VIQ, in primary school students, and the adverse effects of sleep deprivation are mainly seen in students with moderate and severe sleep deprivation.

OBJECTIVETo study the adverse effects of sleep problems and sleep insufficiency on attention in class and pupils' acadamic achievements.

METHODSA total of 1138 students from four primary schools at ages of 6-12 years were randomly sampled from four districts of Changsha city, Hunan Province June 2009 to April 2010. The inquired items included sleep problems, sleep time, sleep quality, attention in class and academic achievements. Teachers and parents observed the pupils according to the unified requirements for 3 months and then filled out the questionnaires.

RESULTSThe total valid inquiry tables were 1091 with the answering rate of 95.87%, including 549 boys and 542 girls. The sleep quality was more poor in children with sleep problems or sleep insufficiency than in children with normal sleep. The sleep quality was reduced and aggravated along with the increasing sleep problems and the reducing sleep time. The attention in class and academic achievements in children with sleep problems or sleep insufficiency were more poor than in children with normal sleep. The sleep quality index was negatively correlated with attention in class and academic achievements. The attention in class was positively correlated with academic achievements.

CONCLUSIONSThe decline in sleep quality directly affects the attention in class and reduce the academic achievements in primary school children.
