BACKGROUND: Myelination following axonal regeneration is a key factor affecting the recovery of spinal cord injury. Oligodendrocyte survival directly affects the myelination following axonal regeneration. OBJECTIVE: To investigate the feasibility of differentiation of rat bone marrow mesenchymal stem cells (BMSCs) into oligodendrocytes induced by neurotrophic factors. DESIGN, TIME AND SETTING: The cell molecular biology in vitro study was performed at the Laboratory of Department of Orthopaedics, Tongji Hospital from September 2006 to June 2007. MATERIALS: A total of 5 Sprague Dawley rats aged 2-4 weeks, of both gender were selected. Bilateral femur and tibia bone marrow was obtained to harvest BMSCs. METHODS: At passage 4, BMSCs were incubated in serum-free medium, supplemented with N2, 20 ng/mL basic fibroblast growth factor, 20 ng/mL epidermal growth factor for 48 hours, and incubated in medium containing 500 ng/mL insulin-like growth factor I and N2 for 3 days. MAIN OUTCOME MEASURES: Morphological changes were observed using an phase contrast microscope. Semiquantitative RT-PCR was utilized to detect specific marker mRNA expression of oligodendrocytes. Using neuron marker anti-microtubule-associated protein, astrocyte marker anti-glial fibrillary acidic protein, oligodendrocyte marker anti-galactocerebroside, anti-myelin basic protein antibody, immunocytochemical staining was performed to detect the positive rate of the differentiation of BMSCs into oligodendrocytes. RESULTS: Morphological changes in BMSCs during the differentiation into oligodendrocytes: After the induction, a majority of BMSCs presented the morphological characteristics of oligodendrocytes. Cytoplasm retraction towards nucleus, cell process extension towards outwards, and strong refraction were found. With the prolongation of time, several cell processes connected and formed a typical net-shape structure. Specific marker mRNA expression of oligodendrocytes: Following induction, specific strap of myelin basic protein mRNA and galactocerebroside mRNA could be detected. Positive rate of oligodendrocytes: During induction, the positive rates of galactocarebroside, myelin basic protein and microtubule-associated protein were 65%, 45% and 10%, respectively. CONCLUSION: The combination of epidermal growth factor, basic fibroblast growth factor and insulin-like growth factor can effectively promote the directional differentiation of BMSCs into oligodendrocytes.

Objective To compare the application of Goldman , CARPREG and ZAHARA in predicting cardiac outcomes in pregnant women with congenital heart disease. Methods A retrospective analysis of 144 pregnant women with CHD , enrolled in The Third Affiliated Hospital of Guangzhou Medical University between Jan 1992 and June 2015 was conducted. The mortality and the incidence of cardiac events were counted by three risk estimation methods. The sensitivity and calibration of three systems were compared by using Hosmer-Lemeshow goodness of-fit analysis and Aera Under Curve (AUC). Results In terms of mortality rates, the sensitivity of CARPREG was higher than that of Goldman (AUC:0.874 and 0.889 respectively;P = 0.568 >0.05);. In terms of the incidence of cardiac events, the sensitivity of ZAHARA was higher than that of Goldman (AUC:0.912 and 0.773 respectively;P = 0.063 > 0.05); Conclusions All 3 risk estimation methods have good performance in sensitivity of predicting the incidence of cardiac events and mortality in pregnant women with CHD. The ZAHARA has a better calibration in predicting the incidence of cardiac events , and we recommend ZAHARA as the first choice of evaluation system for this kind of patients.

Objective To explore the association between psychiatric disorders and socioeconomic status such as education,income,employment and area of community settings in Zhejiang province.Methods Data were from the epidemiological survey of mental illnesses aged 15 and older in 2001(n=14 632).Psychiatric disorders were measured by GHQ-12 with a cut-point 4.Logistic multilevel analysis was the main statistical method being used.Results The overall prevalence of psychiatric disorders was 18.5%(95% confidence intervals,17.9% to 19.1%),higher than the data from Hebei province(u=4.39,P＜0.001).Annual household income and employment were strongly associated with psychiatric disorders especially for those with low income(odds ratio 3.45,95%CI:1.72-6.67)and unemployment(odds ratio 2.03,95%CI:1.73-2.40).Factors as regional effect and education level showed weak or inconsistent association with psychiatric disorders after controlling on other indicators.Conclusion Inverse gradient relation between psychiatric disorders and SES seemed as the main result of low SES individual characteristics and some minor effects at the county level.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

In this study, hydrophilic matrix sustained release tablets of total lactones from Andrographis paniculata were prepared and the in vitro release behavior were also evaluated. The optimal prescription was achieved by studying the main factor of the type and amount of hydroxypropyl methylcellulose (HPMC) using single factor test and evaluating through cumulative release of three lactones. No burst drug release from the obtained matrix tablets was observed. Drug release sustained to 14 h. The release mechanism of three lactones from A. paniculata was accessed by zero-order, first-order, Higuchi and Peppas equation. The release behavior of total lactones from A. paniculata was better agreed with Higuchi model and the drug release from the tablets was controlled by degradation of the matrix. The preparation of hydrophilic matrix sustained release tablets of total lactones from A. paniculata with good performance of drug release was simple.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.
