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 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.

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 We investigated if the proliferative capacity of endothelial progenitor cells was affected by hypoxia and exercise. Methods Twenty four male Sprague-Dawley rats were randomly and averagely divided into 4 groups: (1) living at low altitude (LL), (2) living and training at low altitude (LLTL), (3) living at high altitude (LH), and (4) living at high altitude and training at low altitude (LHTL). Eight-week incremental treadmill exercise and hypoxic simulation were used to establish LHTL animal model. Mononuclear cells from peripheral blood were obtained by density gradient centrifugation 12 hours by the end of 8-week experiment. The cells were suspended in conditioned medium 199 for culturing in vitro. Their phenotypes were confirmed by uptake of acetylated LDL and binding of fluoresce in isothiocyanate (FITC)-labeled Ulex europaeus agglutinin 1 (UEA-1) lectin. Inverted microscopic observation was used to identify the morphological changes in endothelial progenitor cells and measure the cell count. Results Adherent cells and early CFUs in groups LLTL, LH and LHTL increased more obviously than in group LL(P<0.01), whereas the number of attached cells between group LH and LHTL was not different (P>0.05). Conclusion Proliferative capacity of endothelial progenitor cells can be promoted by both hypoxic stimulation and exercise, and the promotion is more significant if combination of hypoxia and exercise was employed simultaneously.

Objective To search for the metabolites that associated with articular cartilage damage in the urine of rat model with articular cartilage destruction induced by T-2 toxin.Methods Thirty healthy male Wistar rats aged 4-5 weeks were numbered by weight,randomly divided into two groups (n =15 per group),namely the control group and the model group.The rats in the control group were fed with standard rat diets,and those in the model group were given diets contaminated by T-2-toxin (300 μg/kg).Throughout the experiment,all animals were given free access to distilled water and diets.After continuous treatment for 3 months,all the rats were sacrificed.The changes of articular cartilage in rat knee joints were observed by histopathological method,the metabolic profile of rats' urine was determined by ultra performance liquid chromatography/quadrupole time of flight-mass spectrometry (UPLC/QTOF-MS) technique.Combined with multivariate statistical analysis,database searching was applied to explore and confirm the different metabolites associated with cartilage damage.Results Light microscope showed that rats' articular chondrocytes in the control group presented cells in neat rows and eumorphism,rats' articular chondrocytes in the model group presented extensive areas of chondrocyte degeneration,necrosis and loss.In rats' urine metabolic profiles,5 different metabolites associated with cartilage destruction were detected,such as 4-hydroxynonenal (HNE),trans-4,5-epoxy-2(E)-decenal (EDE),5-methyldeoxycytidine,and 5-L-glutamyl-glycine and prolyl-valine.Compared with the control group (mass spectrum peak area:65820 ± 5200,22080 ± 3538,4292 ± 3520,3277 ± 2025,1104 ± 990),all of them increased in the model group (mass speetrum peak area:90240 ± 18863,25610 ± 5071,9702 ± 6562,6029 ± 3905,4144 ± 5322,t =-3.903,-2.209,-2.814,-2.424,-2.174,all P ＜ 0.05).Conclusions The articular cartilage destruction induced by T-2 toxin could cause the changes of related metabolites in the urine;the 5 kinds of changed metabolites in urine are related to articular cartilage destruction.
