Objective The prevalence rate of type 2 diabetes mellitus in schizophrenia patients were significantly higher than normal people.The study examined the glucose metabolism in first-episode, drug-naive patients with schizophrenia. Methods Case-control study was employed.According to the 4th edition of American Diagnostic and Statistical Manual of Mental Disorders, 58 first-episode, drug-naive patients with schizophrenia hospitalized in our hospital were collected for the study.Brief psychiatric rating scale, Hamilton depressive scale and assessment of abnormal involuntary movement were used to assess the mental state and the degree of illness.Meanwhile, 60 hospitalized Han patients in the Second Hospital of Lanzhou University were selected as the control group. Fast plasma glucose (FPG) were detected in the morning on each patient along with oral glucose tolerance test (OGTT).Measure-ments were also made on height, body weight, waist circumference, hip circumference, as well as WHR and body mass index (BMI). Results No significant difference was found in gender, age, diet habit, activity, BMI and the number of education years between the groups(P>0.05).The average FPG of the patient group was higher than that of the control group(5.29 ±0.83 mmol/L vs 4.37 ±0.54 mmol/L);postprandial 2 hour glucose of the patient group was significantly higher than that of the control group ( 6.89 ±0.98 ) mmol/L vs 5.97 ±0.82 mmol/L, P<0.05).Statistical difference in the incidence of impaired glucose tolerance( IGT) was found between the two groups, 8 paitents in patient group(13.8%), 2 in control group(3.3%) (χ2 =4.25,P<0.05).Patients with normal and ab-normal glucose tolerance showed no difference in mental state and illness degree(P>0.05). Conclusions First-episode, drug-na-ive patients with schizophrenia have more impaired fasting glucose tolerance than normal people.In order to identify and intervene the abnormal glucose metabolism of schizophrenia patients, it is of great importance to measure relation index to glucose metabolism, espe-cially the oral glucose tolerance test.

Objective To investigate the relationship between the pattern of infarct distribution on diffusion-weight imaging (DWI) and progressive movement deficits (PMD) in patients with infarct in the perforator territory of the middle cerebral artery (MCA). Methods The patients with new infarction in the perforator territory of MCA were analyzed retrospectively. PMD was defined as an increase of at least 2 points on the motor item of the National Institutes of Health Stroke Scale (NIHSS) score persisting for at least 24 hours within 5 days of stroke onset. The demographic characteristics, risk factors, clinical presentation, and distribution characteristics of the infarcts in the PMD and non-PMD groups were compared. Results A total of 64 patients were enrol ed in the study, including 38 females and 26 males, aged 67. 5 ± 10. 8 years. There were 28 patients in the PMD group and 36 in the non-PMD group. The proportion of the infarcts located in the posterior paraventricular region (67. 8% vs. 25. 0%; χ2 =11. 5, P<0. 05) of the PMD group and the mean baseline NIHSS score (6. 9 ± 1. 8 vs. 4. 3 ± 1. 2; t=2. 42, P<0. 05) were significantly higher than those of the non-PMD group. Multiple logistic regression analysis showed that the posterior paraventricular type infarcts had significantly independently correlation with PMD (odds ratio 6. 31, 95% confidence interval 2. 20-18. 0; P<0. 001). Conclusions The posterior paraventricular type infarcts on DWI can be used as a neuroimaging marker for predicting PMD in patients with infarction in the perforator artery territory of MCA.

ObjectiveTo probe into the maternal care utilization by minority women, for the purpose of policy recommendations on better maternal care in minority areas. MethodsA combination of stratified random sampling and typical sampling was made on 445 married women of reproductive age in six counties in Yunnan, Guizhou, Qinghai and Tibet provinces, a field survey on their utilization of maternal care services. ResultsTheir average prenatal detection rate is 78.24％, a level lower than the national rural average of 93.7％ and grade-4 rural average of 81.2％ in 2008; their post partook rate is 30.7％, lower than the national rural average of 54.3％ and grade-4 rural average of 58.9％ in the same period; their average coverage rate is 52.18％, a level lower than the national rural average of 87.1％and grade-4 rural average of 64.3％ in 2008. ConclusionThe maternal care utilization is found to be low for women in minority areas. Effective solutions are expected for payment of indirect expenditure of hospital delivery; better health education for enhancing health knowledge and health awareness of minority women; effective incentive mechanism for village doctors, consolidating the base of the three-level healthcare network.

Objective To obtain recombinant human granulysin using prokaryotic expression system. Methods Total RNA was extracted from cultured PBMC. Granulysin gene segments were obtained with granulysin-specific primers by RT-PCR and then inserted into pET32a(+) plasmid. After identification by DNA sequence, pET-GN-LY9K and pET-GNLY15K were transferred to E. Coli Rosetta (DE3). The fusion protein was identified by SDS-PAGE and Western blot. The bioactivity of granulysin fusion protein was measured by MTT assay. Results The prokaryotic expression vectors pET-GNLY9K and pET-GNLY15K were successfully constructed. The corresponding protein was highly expressed in E. Coli. Recombinant protein was specifically bound by anti-granulysin antibody. GNLY9K fusion protein significantly inhibited the growth of A549 cells in a dose-dependent manner, while GN-LY15K had little effect on the growth of A549. Conclusion Granulysins with different mw were successfully expressed using prokaryotic expression system, which might be helpful for the further study of granulysin.

Objective: In order to validate the effectiveness of methods of defining poverty caused by illness which are based on catastrophic health expenditure and impoverishment health expenditure, originated from relative costs theory.Results: This paper uses empirical approach to explore the definition methods by comparing the original methods with modified methods and defined population with the actual situation of poverty alleviation.Results: Study results show that the catastrophic health expenditures incurred ratio is about 20% and shows the aggregation of both low-income and high-income groups.The impoverishment health expenditure incurred ratio is about 12% and they mainly are families at the edge of poverty line.This study found that 70% of the families defined based on our method did not receive medical assistance in reality.Conclusion: Therefore, the definition methods based on relative costs theory are of great value in Chinese medical assistance systems for defining poverty caused by illness.Grouping based on household ability to pay could improve the methods' operability and effectiveness.

OBJECTIVE:To prepare the vinorelbine-tetrandrine liposomes modified with RGD,and study the inhibitory effect on glioma C6 cells. METHODS:Film dispersion method and ammonium sulfate gradient method were used to prepare the vinorel-bine-tetrandrine liposomes modified with RGD,and the morphology and particle size distribution were observed. The vinorelbine content was determined,and sulforhodamine B method was used to respectively determine the inhibitory effects of blank targeting liposomes,normal vinorelbine liposomes and vinorelbine-tetrandrine liposomes modified with RGD on C6 cells. RESULTS:The prepared vinorelbine-tetrandrine liposomes modified with RGD were spherical or almost spherical with smooth surface,and particle size was about 120 nm. The average content of vinorelbine was 28.27 μg/mL(RSD=0.38％,n=3). Blank targeting liposomes had no significant effect on the growth of C6 cells;vinorelbine-tetrandrine liposomes modified with RGD can obviously inhibit the growth of C6 cells,and cell viability after its effect was significantly lower than normal vinorelbine liposomes (P<0.05). CON-CLUSIONS:Vinorelbine-tetrandrine liposomes modified with RGD are successfully prepared,and they show obvious inhibitory ef-fects on the growth of C6 cells.

Objective To explore the clinical characteristics and treatment of infants with cytomegalovirus(CMV)pneumonia.Methods The clinical and auxiliary examination data of 24 patients with CMV pneumonia,which were diagnosed by detection of serum CMV-IgM used enzyme immunodot technique.All patients were treated with ganciclovir (GCV).Results The most common clinical manifestations of CMV pneumonia were cough,breathlessness,fever,crackles and wheezing rale.Chest X-ray findings predominately revealed increased and thickened bilateral lung markings and patchy areas of increased opacity in both lungs.Sixteen cases were cured,8 cases improved.Conclusions Clinical manifestations of infant CMV pneumonia lack specificity.The presence of serum CMV-IgM antibody is a laboratory diagnostic evidence.GCV is the best choice of drug in treatment of infants with CMV pneumonia.
