Objective To understand the dietary intake and nutritional status of pregnant women, and try to give a reasonable suggestion to promote the development of fetus. Methods 227 pregnant women in Changsha city were enrolled in this study. Their serum levels of vitamins were detected and their dietary intake were investigated. Results The ratio of the energy which was provided by dietary protein, carbohydrate and fat was appropriate. But the intake of dietary calcium, vitamin B1 and vitamin B2 was very low. With the development of gestation there were a remarkable rise in serum vitamin E level and decrease in serum folacin level, which was extremely obvious in the third trimester. It was about 40% of the pregnant women that the serum vitamin C level was lower than normal level. Conclusions Pregnant women tend to be lack of folacin, vitamin C and vitamin B 2.

Objective To understand the needs for and supply of clinical research consultation at the clinical epidemiological unit (CEU) in a general hospital. Methods Data were collected from work records of 2008 of CEU and were analysed. Results There were three faculties and three graduate students in the CEU, who altogether provided 272 consultations in 2008. 147 of the consultants were doctors (54.0%), and 90 were graduate students (33.1%). With regard to the content of consultation, 106 (39. 0%) were for bio-statistical methods, 96 (35. 3%) for project design, 36(13.2%) for paper writing and 24 (8.8%) for others. The professor of the CEU provided more consultation on project design (71/139, 51.1%) than assistant professors (22/151, 19.1%) and graduate students (3/18, 16.7%) (P＜0.01). The assistant professors (66/151, 57.4%) and graduate students (10/18, 55.6%) provided consultation on bio-statistical methods more than the professor (30/139, 21.6%) (P＜0. 01). Conclusion Doctors and graduate students in the general hospital need clinical research consultation service from the CEU. It is necessary and possible to establish a CEU in general hospital to meet the needs of clinical epidemiological consultation. The free consulting policy is effective in improving the accessibility and satisfaction of the consulting service.

Objective To explore the difference of DNA methylation levels between normal Schwann cells (NSCs) and activated Schwann cells (ASCs) in rats. Methods The adult Wistar rats were received sciatic nerve ligation and fed for 7 days. The ASCs and NSCs were separated from ligated sciatic nerves and brachial plexus respectively. Immunocytochemical staining of S-100 antibody was used to identify the cells. The growth condition of cells was detected by CCK-8 method. Methylated DNA immunoprecipitation sequencing (MeDIP-Seq) was applied to filter the differentially methylated regions in ASCs and NSCs. The distribution of differentially methylated genes related with axonal regeneration in chromosome was analyzed, and Gene ontology(GO)and PATHWAY analysis were also conducted. Results High purity of ASCs and NSCs were obtained successfully, which were both positive for S-100 antibody. In the same culture condition, ASCs showed a faster proliferation than that of NSCs. A total of 177 176 differentially methylated regions were found by MeDIP-Seq. Among them, 1 097 were located in the promoter (≤1 kb), 1 136 in the promoter (1-2 kb) and 567 on the CpG. After functional annotation of differentially methylated genes, 214 differentially methylated genes related with axonal regeneration were found in ASCs and NSCs. Compared with NSCs, 191 genes were up-regulated and 23 genes were down-regulated in ASCs. These genes were located on different chromosomes, most of which on chromosome 12 (22 genes) and the least on chromosomes M (2 genes). GO analysis indicated that the differential methylated genes were involved in axon growth, axon formation, axon elongation and axon guidance. The MAPK, cell adhesion molecules, Ras signaling pathway may be related with the differential methylated genes. Conclusion The methylation levels between ASCs and NSCs are significantly different, which are probably related with axon regeneration.

AIM To observe the effects of ZMS and ZMR(isomer of ZMS),two active components of Zhimu on learning and memory ability and muscarinic subtype M 1 receptor density in aged rats. METHODS 24 month-old SD rats were randomly divided into aged control group, ZMS and ZMR treatment group. Young rats were used as normal control group. The learning and memory ability was detected by Y-maze method. The muscarinic subtype M 1 receptor density in the brain was detected by 3H-QNB binding tests. RESULTS It was found that daily oral administration of ZMS and ZMR for 40 d significantly enhanced the learning and memory ability and the muscarinic subtype M 1 receptor density in the brain of the aged rats. CONCLUSION These results suggested that ZMS and ZMR probably have potential preventive and curative action for the progressive deterioration of the cholinergic system in Alzheimers disease (AD).

Aim To study antiangiogenesis and antitumor of thalidomide.Methods In HUVECs, cell viability was determined by MTT assay;death type was observed by electron microscope; ratio of apoptosis was quantitated by flow cytometry.Angiogenesis was tested in chicken embryo chorioallantoic membrane.Effect of thalidomide on S_(180) was examined in homograft mice and microvascular counts were detected through immunochemical staining method.Results Thalidomide might inhibite the growth of HUVECs with a IC_(50) value of(22.91?1.74) ?mol?L~(-1),cells treated by thalidomide for 48 h displayed morphological characteristics of different stages associated with apoptosis,which were irregular nucleus, condensed chromatin, ballooning endoplasmic reticulum, apoptotic bodies,under electron microscope.Thalidomide might be able to cause apoptosis or necrosis of HUVECs in flow cytometry and raised positive of antiangiogenesis with increasing of dosage in chicken embryo chorioallantoic membrane. Thalidomide as a single agent might not significantly prevent tumor growth but decrease microvascular counts in tumors, however, in combination with cyclophosphamide, thalidomide could decrease dosage of cyclophosphamide and enhance antitumor of cyclophosphamide.Conclusion Thalidomide might hold back angiogenesis,as a single agent, could not significantly prevent S_(180) tumor from growing,but acted synergistically with cyclophosphamide.

[ ABSTRACT] AIM:To explore the role of SHARPIN in regulation of Rip1 in castration-resistant prostate cancer LNCaP-AI cells.METHODS:The LNCaP-AI cells were treated with TNF-α+Z-VAD ( an inhibitor of pan-caspase) to activate necroptosis, which were compared to the cells treated with TNF-α+Z-VAD+Nec-1 ( an inhibitor of Rip1 ) .A blank group and a TNF-α-treated group were set up as controls.The cell viability in each group was measured by MTS as-say.In addition, SHARPIN was knocked down by siRNA, and the inhibitory efficiency was evaluated by RT-qPCR.The expression of Rip1 at mRNA and protein levels after knocking down SHARPIN was determined by RT-qPCR and Western blot to explore the underlying mechanism of regulatory network of necroptosis in prostate cancer.RESULTS: Compared with blank control group and TNF-α-treated group, the viability of LNCaP-AI cells treated with TNF-α+Z-VAD decreased by 28%(P<0.05).After treated with TNF-α+Z-VAD+Nec-1, the LNCaP-AI cells showed no significant difference in the viability compared with blank control and TNF-α-treated groups.Taken together, necroptosis may be an important way of cell death in LNCaP-AI cells.Besides, the expression of Rip1 at protein level was up-regulated following the inhibition of SHARPIN using siRNA, indicating that down-regulation of SHARPIN enhanced necroptosis via activating Rip1 in
LNCaP-AI cells.CONCLUSION:Necroptosis is an important way of cell death .Inhibition of oncogenic factor SHARPIN enhances necroptosis via activating Rip1 in LNCaP-AI cells.
