Objective To determine how genetic polymorphisms in norepinephrine transporter (NET) gene influence the response of antidepressant treatment and how they interact with childhood trauma and recent life stress in a Chinese depressive patients.Methods 281 Chinese Han depressive patients received single antidepressant drugs for 6 weeks.Hamilton Depression Scale-17 (HAMD-17),the Childhood Trauma Questionnaire short term (CTQ-SF) and the Life Events Scale (LES) were used to evaluate severity of depressive symptoms and the occurrence of stressful life events respectively.Three single nucleotide polymorphisms (SNPs) in norepinephrine transporter were genotyped.Associations of single locus and haplotypes with antidepressant treatment response were analyzed using UNPHASED 3.0.13.The interaction of gene and life stress was analyzed by SPSS13.0 software.Results One NET SNP rs2242446 was significantly associated with antidepressant response in this Chinese male sample(0.4118vs0.2375,x2=7.046,P=0.0079,OR=0.445,95％ CI (0.243-0.815)),as was the haplotype CG(rs2242446 and rs5569;x2 =5.886,P=0.0153,OR=0.457,95％ CI (0.198-1.054)) and another haplotype CG-G(rs2242446,rs1532701 and rs5569;x2=5.360,P=0.0206,OR=0.530,95％ CI (0.202-1.386)) of NET in male samples.The NET SNPs rs5569 demonstrated interaction with childhood trauma to influence antidepressant response(β=-2.727,SE =1.195,P=0.023,OR=0.065,95％ CI (0.006-0.681)).Conclusion Antidepressant drug response was influenced by not only NET genetic polymorphisms in norepinephrine transporter gene but also interaction between the NET genetic polymorphisms and early life stress.

10mm in diameter) which were mostly non-functional ones(63.3%), and 12 microadenomas(≤10mm in diameter) which were mostly functional ones(91.7%). Only macroadenonas had abnormal imaging in DR, DSA, while microadenomas had no change in above radiological examinations. Microadenomas appeared in low density on CT or hypointensity in MRI as the direct signs, and CT, MRI contrast enhancement raised its display rate greatly. Macroadenomas showed various contrast in the post enhancement CT or MRI. Contrast enhancement of CT or MRI were capable of delineating size, location, extent of the tumor and the remaining intact pituitary tissue. Conclusion MRI Gd-DTPA contrast enhancement scaning is the first-selecting method to diagnose the pituitary adenomas especially the clinical suspected cases.

Objective To investigate the percentage of CD5-positive B cells in peripheral blood mononuclear cells(PBMC) of patients with chronic HCV infection and its clinical significance.Methods The expression of CD5 molecule on B cell surface was detected by flow cytometry and HCV RNA copies were detected by real-time PCR.Results The percentage of CD5+-B cells significantly increased in the patients with chronic HCV infection(58.4%?9.8%) compared with healthy controls(22.5%?5.9%)(P

Objective: To establish a method to determine 5 hazardous elements in animal traditional Chinese medicines (TCM) by microwave digestion-inductively coupled plasma mass spectrometry (ICP-MS).Methods: HNO 3-H 2 O 2 was used to decompose animal TCM, the working parameters of ICP-MS were optimized, and the matrix effect and the mass spectrum interferences were corrected by the in-line addition of Ge, In and Bi internal standard solution and the collided reaction cell technology (KED mode), respectively.Results: The detection limits of 5 hazardous elements were within the range of 0.04-0.52 μg·L-1 , the relative standard deviations (RSD) were within the range of 1.1%-4.8% , and the recoveries were within the range of 92.4%-110.0%.The method was applied to determine the 5 hazardous elements in 40 batches of animal TCM.The results indicated that some kinds of hazardous elements in animal TCM were high, and more attention should be paid to the problems in the production and use of animal TCM.Conclusion: The analysis method is simple, rapid and accurate, and suitable for the determination of hazardous elements in animal TCM.

Objective To evaluate the safety and efficacy of mesohepatectomy for large and centrally located hepatocellular carcinoma.Methods A retrospective study was carried out on 136 pa tients who underwent mesohepatectomy for large and centrally located hepatocellular carcinoma at Xiangya Hospital,Central South University,from 2001 to 2007.Intraoperative/post operative data and long-term survivals were analyzed.Results Vascular occlusion time,operative time,intraoperative blood loss,intraoperative blood transfusion and hospital stay were (13.3 ± 9.1) min,(173.1 ±41.1)min,(548.7±320.5)ml,(511.4±231.7)ml and (18.6±8.8)d,respectively.Four patients developed major complications.There was no in-hospital death.The 1-,3-,and 5-year overall survival rates and disease-free survival rates were 71％,46％,29％ and 65％,40％,24％,respectively.Conclusions Mesohepatectomy for large and centrally located hepatocellular carcinoma preserved the maximum amount of functional liver parenchyma.It is safe and reliable and may be used as the treatment of choice.

OBJECTIVE: To study the assistant effect of Scutellaria barbata extract (ESB) in 5-fluorouracil (5-FU) chemotherapy. METHODS: A mouse model of transplanted hepatoma H22 was used in this study to evaluate the synergic and attenuating effects of ESB in chemotherapy. Tumor inhibition rate, life span of mice and the toxicity of chemotherapy were observed. The body weight, tumor weight, thymus index and spleen index in H22-bearing mice were also measured. The phagocytotic function of macrophages was studied by observing phagocytization of peritoneal macrophages. RESULTS: The increase of body weight in 5-FU plus ESB groups was higher than that in 5-FU group, and the side effects such as anorexia, abdominal distention and athrepsy were relieved. Compared with untreated group, prolonged lifetime in 5-FU plus high-dose ESB group and 5-FU plus low-dose ESB group was improved. Life prolongation rates in 5-FU plus high-dose ESB group and 5-FU plus low-dose ESB group were 61.46% and 23.59% respectively. High-dose ESB, 5-FU, 5-FU plus low-dose ESB and 5-FU plus high-dose ESB could inhibit the tumor growth, and the tumor inhibition rates were 36.98%, 42.26%, 52.45% and 65.28%, respectively. Thymus index and spleen index were increased significantly in 5-FU plus low-dose ESB group and 5-FU plus high-dose ESB group. White blood cell (WBC) count was decreased obviously in 5-FU group, while the count of WBC was increased in 5-FU plus low-dose ESB group and 5-FU plus high-dose ESB group. The phagocytotic function of macrophages was also increased in 5-FU plus low-dose ESB group and 5-FU plus high-dose ESB group. CONCLUSION: ESB can enhance the effect of chemotherapy, relieve the side effects and improve immune function of mice in chemotherapy. These results suggest that ESB, as a biochemical modulator to enhance the therapeutic effects, is useful in cancer chemotherapy.

Objective To sequence and analyze the envelope (E) gene of type Ⅰ dengue virus isolated from Guangzhou in 2009 for tracing the infection source. Methods The serum samples were collected from patients diagnosed with dengue fever in Guangzhou area during 2009. Dengue virus was isolated and cultured in C6/36 cells.The whole length of E gene was amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) and then sequenced. The phylogenetic tree was drawn by neighbor-joining method. The bioinformatics analysis was performed by combining the phylogenetic information and the epidemiology data. Results Four strains of type Ⅰ dengue virus were isolated from 19 samples. E gene of these strains was amplified and sequenced. The phylogenetic analysis showed that 09/GZ/9104 strain and 09/GZ/9236 strain had identical nucleotide sequence and fell within the American/African group, 09/GZ/11534 stain and 09/GZ/11562 strain had similar sequence homology and fell within the Asian group. Conclusion The typeⅠdengue viruses in Guangzhou area in 2009 are imported, which belong to two genotypes and may come from two independent origins respectively.
