Objective To investigate the adjuvant therapeutic efficacy of three-dimensional conformal radiotherapy (3D-CRT) in treating patients who underwent surgical operation for biliary drainage.Methods Clinical data on 88 clinically diagnosed advanced pancreatic head carcinoma patients who received palliative biliary drainage surgery in Tanshan Gongren Hospital from Jan 2006 to Jan 2010 were retrospectively reviewed. The cases were categorized according to the treatment into control group ( n=34 ) , chemotherapy group ( n=23 ) and radiotherapy group ( n=31 ) . The patients in control group received no chemotherapy or radiotherapy after biliary drainage surgery.The patients in chemotherapy group received chemotherapy of 1 000 mg/m2 gemcitabine intravenous infusion on day 1 and day 8, 80 mg/m2 cisplatin intravenous infusion on day 1 for each treatment cycle.Each cycle lasted for 21 days and was repeated for 3 cycles at an interval of 7 days in a treatment course.Patients in radiotherapy group received 3D-CRT for 6 successive days followed by an interval on the 7th day.The treatment course was completed within 10~15 days with the total dosage of 3 000~4 800 cGy.The therapeutic effects and survival time were analyzed.Results The incidence of cancer associated pain was 52.9%, 39.1%and 9.7%in control group, chemotherapy group and radiotherapy group, respectively, which was significantly lower in radiotherapy than that in the other two groups (both P<0.05). The incidence of mild gastrointestinal symptoms was 8.8%, 73.9% and 16.1%, respectively, and that of bone marrow suppression was 0%, 82.6% and 9.7%, respectively, which were both significantly lower in radiotherapy group than in chemotherapy group (both P<0.05).The 1-year, 2-year and 3-year survival rate was 30.1%, 8.3%, 0% in control group, 35.3%, 14.8%, 0% in chemotherapy group and 46.4%, 21.1%, 3.6%in radiotherapy group, which in radiotherapy group was significantly higher than that in control group and chemotherapy group (all P<0.05).Conclusions 3D-CRT was a palliative strategy for advanced pancreatic head cancer, which could prolong the survival of patients.

Objective: To explore the influence of awareness on the behaviors of Chinese adults with diabetes mellitus, so as to provide scientific evidence for developing relevant policies and strategies in the prevention and control of diabetes.Methods: Data from the 2013 China Chronic Disease Risk Factor Surveillance were used, covering 297 surveillance counties (districts).The variables involved in this cross-sectional study included: the prevalence of diabetes, the awareness situation, demographic characteristics, behaviors, and other information.The study used descriptive analysis to analyze diabetes status and chi-square test to determine the difference in the distribution of behaviors between patients who were aware of their disease and those who were not.Logistic analysis was performed to examine the influence of diabetes awareness on patients' behaviors with adjustment for potential confounders.Results: A total of 175 670 subjects were involved.The prevalence of self-reported diabetes in China in 2013 was 3.9%, while the awareness rate was 38.6%.The percentage of current smokers or current drinkers among the patients who were aware of their disease (20.2%, 25.0%) was less than that among the patients who were not aware (25.8%, 35.0%).The proportion of those who often exercised among the patients who were aware of their disease (83.4%) was higher than that among the patients who were not aware (79.0%).There was slightly higher proportion of the subjects who had insufficient intake of vegetables and fruits or over intake of red meat among the patients who were aware of their disease (49.4%, 28.0%) than that among the patients who were not aware (48.4%, 26.1%).After controlling urban and rural areas, regions, age, gender, nationality, marital status, educational level, occupation, and income factors, the possibility of current smoking (OR=0.79) or drinking (OR=0.58) among the patients who were aware of their disease was lower than among those who were not;the possibility of more than 150-minute physical activity per week (OR=1.30) among the patients who were aware of their disease was higher than among those who were not.Conclusion: The awareness rate of diabetes in China still remains low.Kno-wing whether they have diabetes or not has an effect on individual choice of behaviors, including smoking, drinking and physical activities.Therefore, health education and health examination for diabetes should be further expanded with wide cooperation from all relevant departments, thus forming an integrated environment involving individuals, health systems and socioeconomic policies to prevent and control diabetes.

Objective To observe the protective effect of asiatic acid on hyperlipidemia golden hamsters induced by high fat diet and explore its mechanism.Methods Hyperlipidemic golden hamsters fed with high-fat diet were administered orally with asiatic acid (8,16,32 mg/kg)for 4 weeks.Levels of serum lipid content,liver histology,hepatic GSH-PX and SOD levels,serum ALT and AST activities were evaluated in golden hamsters,fluorescence quantitative polymerase chain reaction(RT-PCR)is using to examine the liver lecithin cholesterol fatty acyl transferase(LCAT) and class B typeⅠscavenger receptor(SR-BⅠ)mRNA expression. Results Compared with model group,the levels of TC,TG,LDL-C,TC/HDL,ALT and AST in low and mediate asiatic acid groups were all significantly decreased but the levels of SOD and GSH-PX were significantly increased(P<0.01).HE staining results showed that fat deposition in the liver were improved by administration of asiatic acid,and the expression of LCAT and SR-BⅠmRNA were increased.Conclusion Asiatic acid can effectively reduce blood lipid levels,and alleviate liver damage of the hyperlipidemia golden hamsters by lipid regulation and antioxidative ability augmentation.The increased levels of LCAT and SR-BⅠmRNA expression maybe involved in the mechanism of hypolipidaemic effect of asiatic acid.

Neuron axonal signals play an important role in myelination of central nervous system. Myelination depends on a balance between the positive and negative neuron axonal signals. The positive signals, such as neuregulins (NRG), neuron cell adhesion molecule (NCAM), electrical activity and neurotrophins, have a function of promoting the proliferation and the myelination thickness of ensheathing glial cells, while the negative factors like the L1 protein, poly-sialic acid-neuron cell adhesion molecule (PSA-NCAM), will lead a marked decrease in myelination. Here，we mainly present some well-researched neuron axonal factors and their mechanism.

Objective:To investigate the effects of bezafibrate (BF) on the activation,proliferation and differentiation of CD4+T cells from primary biliary cirrhosis ( PBC) patients and to elucidate the mechanisms for the immunosuppressive effects of BF and to further provide experience basis for BF target therapy PBC.Methods:PBMCs were isolated from PBC patients then CD 4+T cells were selected by MACS, and stimulated with anti-CD3, anti-CD28, in the presence of different concentration of BF.The cytokines were measured by ELISA,and the activation,proliferation and differentiation of CD4+T cells were analyzed by flow cytometry.Results:(1) BF could inhibit the activation of CD 4+T cells in PBC patients.(2) BF could inhibit the proliferation of CD 4+T cells in PBC patients in a dose-dependent manner (P<0.05).(3)BF could down-regulation IFN-γand IL-17 production of CD4+T cells in a dose-dependent manner ( P<0.05 ).Conclusion: BF could inhibit immune responses of PBC patients by suppressing CD 4+T cells activation;proliferation and cytokine production.

Objective To determine whether intravenously transplanted bone marrow stromal cells (BMSCs) could promote recovery of lower urinary tract function in rats with spinal cord transaction.Method The BMSCs were harvested from rats and labeled with 5-bromo-2'-deoxyuridine (BrdU) (30 g/mL) in vitro for 3 days for intravenous transplantation.The BMSCs of 5th passage were characterized by flow cytometry of CD45 and CD90.Twenty-four male Sprague-Dawley rats were divided randomly into three goups.Sixteen rats received a spinal cord transection and a transplantation of cell culture medium (OP-controls,n =8) or BMSCs (n =8).Eight rats were justly given T8-T9 laminectomy (CNS-intact group,n =8).Urodynamic tests,HE staining and immunohistochemistry of the spinal cord with anti-BrdU at 28th day after transplantation were performed.Result The cultured BMSCs of 5th passage expressed 5.94％ of CD45 and 99.4％ of CD90 on flow cytometry.BMSC rats showed significant decrease in residual urine volume (0.85 ± 0.16 mL vs.1.54 ± 0.66 mL,P＜ 0.05),leak point pressure (33.85 ± 3.73 mmHg vs.40.83 ± 3.85 mmHg,P＜0.01),episodes of non-inhibitory contraction (NVC) (2.17 ± 1.12 vs.9.71 ± 3.84,P＜0.01) and increase in voiding efficiency (26.37 ± 6.97％ vs.2.68 ± 1.47,P＜0.01) compared to OP-control rats.In OP-control rats,only tonic EUS activity was remained and busting EUS activity was abolished during bladder filling.While,the tonic EUS activity and busting EUS activity were remained in BMSCs rats.Otherwise,the silent period between EUS bursts was shorter in BMSCs rats (68.86 ± 13.78 ms,P＜ 0.05) and OP-control rats (33.4 ms) than CNS-intact rats (132.79 ± 17.11 ms).Cells derived from BMSCs,identified by 5-BrdU immunoreactivity,survived and were distributed at the damaged tissue (T10),lumbar and sacral spinal cord.Conclusion Intravenously transplanted BMSCs survived in the injured spinal cord,lumbar and sacral cord for rebuilding new voiding reflex and inhibiting afferent sprouting leading to baldder dysfunction.So they had beneficial effects on the recovery of lower urinary tract function in rats with spinal cord transection.
