Objective: To analyze the expression of CMTM1-v17 in normal prostate tissue and prostate carcinoma originated cell lines, and study its impact on the transactivation of androgen receptor and the possible mechanism. Methods: The expression of CMTM1-v17 in normal prostate tissue was analyzed with immunohistochemistry method. In immounocytochemistry was used to analyze the expression of CMTM1-v17 in prostate carcinoma originated cell lines. Luciferase assay was used to study the impact of CMTM1-v17 on the transactivation of AR and its mechanism. Results: The results of immunohistochemistry showed that CMTM1-v17 was highly expressed in prostate. In prostate cancer originated cell lines, CMTM1-v17 could also be detected in prostate cancer originated cell lines PC3, Du145 and LNCaP. And the results of luciferase implied that the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids separately were 70.8 and 34.7, compared with the control set as 100. When trichostatin A, the inhibitor for histone deacetylase, was used, the repression of androgen receptor could be recovered with trichostatin A treatment,for the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids and treated with 100 nmol/L trichostatin A rebound to 90.9 and 86.4. Conclusion: CMTM1-v17 is highly expressed in both normal prostate and prostate carcinoma originated cell lines. It may recruit histone deacetylas to inhibit the function of androgen receptor.

Objective To investigate the expressions of serum cystatin C CysC),retinolbinding protein (RBP),serum and urinary β2-microglobulin (β2-MG) and their effects on predicting renal damage in primary hypertension in elderly patients.Methods A total of 149 patients were divided into 3 groups of hypertension grade 1 (n =50),hypertension grade 2 (n =50) and hypertension grade 3 group (n=49).92 healthy controls who took physical examination were selected as control group.The levels of serum CysC,RBP,serum and uric β2-MG,blood urea nitrogen,creatinine and other biochemical indexes were detected.The complications of hypertension were observed.The differences in renal function indexes between groups and their correlations were analyzed.Results There were 86 cases with hyperlipidemia (57.7％),71 cases with atherosclerosis (47.7％),59 cases with type 2 diabetes mellitus (39.6％),56 cases with coronary heart disease (37.6％),and 49 cases with cerebral vascular disease (32.9％) in 149 hypertensive patients.The levels of serum CysC,RBP,serum and uric β2-microglobulin were increased in hypertensive patients as compared with healthy controls (P＜0.05 or 0.01),and the extents of increments in the above indexes were positively correlated with blood pressure level [CysC:(1.2± 0.5) mg/L,(1.7±0.6) mg/L,(2.2±0.9) mg/L;RBP:(53.1±10.2) mg/L,(65.2±16.3)mg/L,(75.8±17.5) mg/L;serum β2-MG:(2.7±1.5) mg/L,(4.0±2.1) mg/L,(4.9±2.0) mg/L;uric β2-MG:(178.3±73.9) ng/L,(237.9±78.6) ng/L,(277.5±87.5) ng/L;respectively,P＜0.05or 0.01].Conclusions Elderly hypertensive patients are complicated with a variety of diseases.The levels of serum CysC,retinol-binding protein,serum and uric β2 microglobulin have significant diagnostic values on renal impairment caused by hypertension,and can be considered as sensitive factors for early renal impairment in essential hypertension.

BACKGROUND: About one fourth of diabetic patients suffer from diabetic retinopathy(DR) and has greatly impacted their quality of life due to the decreased vision. Social support plays important role on rehabilitation of patients.OBJECTIVE: To analyze the relationship between social support and quality of life(QOL) in patients with diabetic retinopathy in order to direct clinical practice and improve the patients' QOL.DESIGN: Cross-sectional study based on patients with diabetic retinopathy.SETTING: Department of Ophthalmology, General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: Totally 81 patients admitted into Department of Ophthalmology, General Hospital of Nanjing Military Area Command of Chinese PLA with diabetic retinopathy during January 2002 to May 2003 were selected. Inclusion criteria: suffer from diabetic retinopathy and willing to attend this study. Exclusion criteria: people with other complications (hypertension, kidney disease) . The patients were divided into two groups according to vision: 28 cases in the group with binocular vision between 0.06 -0. 1; 53 cases in the group with vision less than 0. 05.METHODS: Investigation was conducted to the two groups from three dimensions including objective support, subjective support and usage in order to assess the social support to patients with diabetic retinopathy of different vision. And modified quality of life index (MQLI) was used to assess the QOL in patients with diabetic retinopathy that covered 5 dimensions: somatic health, mental health, social function, self-image and material base.MAIN OUTCOME MEASURES: The total score of social support and QOL of patients with diabetic retinopathy, score of somatic health, mental health,social functions and material base as well as the correlations among them.RESULTS: The total score of social support, score of objective support factor, subjective support factor and usage factor in roup with vision between 0.06 and 0. 1 were much higher than those in group with vision less than 0.05 ( P < 0.01 ). For patients with diabetic retinopathy, the social support had strong correlation with total score of QOL and factor score of other dimensions except of self-image( P < 0.05 or P < 0.01).CONCLUSION: Social support is an important factor that impacts QOL to patients with diabetic retinopathy. It will improve their QOL by reinforcing the social support.

The response of glueagon to the change of glucose and its relation to blood pressure in 71 eidely patients with type 2 diabetes was investigated. The results showed that the postprandial increment of glucagon in the group of patients with postprandial 2h plasma glucose increment<2.5 mmol/L was significantly higher than that in the group with plasma glucose inerement≥ 2.5 mmoi/L (P<0. 05). The postprandial increment of glucagon in patients with normal blood pressure was significantly higher than that in patients with hypertension (P<0.05). The results suggest that the decreased response of glucagon to the change in plasma glucose in elderly patients with type 2 diabetes is related to increased blood glucose and high blood pressure.

OBJECTIVETo investigate the inhibitory effects of tetramethoxystilbene, a selective CYP1B1 inhibitor, on adipogenic differentiation of C3H10T1/2 multi-potent mesenchymal cells.

METHODSIn vitro cultured C3H10T1/2 cells at full confluence were induced by adipogenic agents (10 µg/ml insulin, 2 µmol/L dexamethasone and 0.5 mmol/L 3-isobutyl-1-methylxanthine) and exposed simultaneously to TMS at the final concentrations of 1.0, 2.0 or 4.0 µg/ml. Oil Red-O staining was used to observe the cell differentiation. The expression of peroxisome proliferator-activated receptor gamma (PPARγ) and its target genes cluster of differentiation 36 (CD36) and fatty acid binding protein 4 (FABP4) were quantified by real-time RT-PCR and Western blotting.

RESULTSOil Red-O staining and TG contents revealed that TMS suppressed induced differentiation of C3H10T1/2 cells. TMS exposure of the cells dose-dependently decreased both mRNA and protein expressions of PPARγ, a key nuclear transcription factor during adipogenesis, and also lowered the mRNA expressions of PPARγ target genes CD36 and FABP4.

CONCLUSIONTMS can suppress adipogenic differentiation of C3H10T1/2 cells by inhibiting PPARγ
