Objective To examine the effect of Pu-Erh tea extract(PTE) on genes expression of lipogenesis in white adipose tissue of rats fed high fat diet.Method Thirty male SD rats were randomly divided into three groups(n=10):the control group(basal diet);the high fat group(high fat diet);the PTE group(high fat diet + Pu-Erh tea extract).Body weight and adipose tissue were measured.Expression of genes regulating lipid metabolism was assessed in adipose tissue.Results PTE supplementation prevented diet-induced increases in body weight and adipose tissue.Diacylglycerol acyltransferase-1(DGAT1),stearoyl-CoA desalurase-1(SCD1) and sterol regulatory element binding protein-1c(SREBP-1c) mRNA levels were markedly decreased in adipose tissue of rats fed PTE.Conclusion This study shows for the first time that Pu-Erh tea extract prevents diet-induced obesity,and this effect is partly mediated via a direct influence on adipose tissue.

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.

METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.

RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.

CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.

AIM: To observe the changes in subfoveal choroidal thickness ( SFCT ) after intravitreal injections of ranibizumab ( IVR ) for macular edema secondary to retinal vein occlusion ( RVO) .
METHODS:Thirty-six eyes of 36 patients with macular edema secondary to RVO) were treated with 0. 5mg IVR monthly for 3mo and received additional IVR as needed over the following 1a period. SFCT of the all eyes ( the affected eyes with RVO and unaffected fellow eyes ) was measured by enhanced depth imaging optical coherence tomography images before and after the IVR.
RESULTS: The mean SFCT of the affected eyes with RVO decreased from 246. 7±115. 0μm at baseline to 220. 5±102.0μm at 1mo (P<0.05), 198.3± 114.0μm at 6mo (P<0.01), 212. 6± 96. 0μm at 12mo (P<0. 01). Whereas the fellow eyes changed from 229. 4±108. 0μm at baseline to 226. 3±107. 0μm at 1mo (P>0. 05), 228. 6±127. 0μm at 6mo (P>0.05), 223.6±101.0μm at 12mo(P>0.05). There were statistically significant difference between affected eyes with RVO and unaffected fellow eyes.
CONCLUSION: The SFCT is decreased after IVR for macular edema secondary to RVO. IVR seems to affect the hemorheology of the choroid.

Objective To study the effects of iodine deficiency and hypothyroidism on protein expression of extracellular signal-regulate kinase(ERK1/2) in the cerebellum of rots. Methods Twenty-eight healthy Wistar rots, female, 60 days old, were randomly divided according to their body weight into control group, iodine deficient group and hypothyroidism groups. Hypothyroidism groups in accordance with drinking water containing propylthiouracil(PTU) were divided into doses of 5 mg/L and 15 mg/L groups, 7 rats in each group. Rats after pregnancy, iodine deficient rats were administered with iodine-deficient diet and hypothyroid rats were administered with PTU in drinking water. Pup's cerebellum in each group were weighed on day 14,21,28 and 42. Cerebellum tissue was observed for cerebellar morphology using silver staining and detected for ERK1/2 protein using immunohistochemistry on day 7,14,21,28 and 42. Results On day 14,21,28 and 42, cerebellum weight of pups from iodine-deficient[(0.0945±0.0233), (0.1347±0.0046), (0.1542±0.0094), (0.1949±0.0048)g]were significantly lighter than control[(0.1856±0.0123), (0.2049±0.0098), (0.2268±0.0065), (0.2606±0.0086)g, all P < 0.05]and hypothyroidism groups [for 5 mg/L group: (0.1741±0.0172), (0.1927±0.0103), (0.2181±0.0064), (0.2583±0.0054)g, all P<0.05; for 15 mg/L group: (0.1604±0.0083), (0.1682±0.0103), (0.1996±0.0073) and (0.2579±0.0067)g, all P< 0.05]the difference had statistical significance(F=6.325,8.870, 16.191 and 21.574, all P<0.05). Compared to the controls on day 7, iodine-deficient group didn't have clear layers; on day 21, disappearance of external granule cells from iodine-deficient and 15 mg/L groups was delayed, still two or three layer external granule cells remained; on day 28 and 42, molecular layer from 5, 15 mg/L and iodine-deficient groups and became thinner. Immunohistochemistry showed that on day 7, there was no statistical difference of integrated optical density average of ERK1/2, in all the groups(F=1.102, P>0.05); on day 14,21,28 and 42, integrated optical density average of ERK1/2 in iodine-deficient group[(7.3245±0.5070), (8.3606±1.0683), (9.1217±1.0402), (12.1587±0.7581), all P<0.01]and hypothyroidism groups [for 5 mg/L group: (11.4307±1.5200), (14.919±0.8497), (16.0082±1.1130), (15.7721±0.8293), all P< 0.01; for 15 mg/L group: (7.8538±0.9775), (11.2461±0.8138),(12.78±1.3783), (13.0871±1.1450), all P < 0.01]was significantly lower than those of controls [(16.2831±0.5143), (20.2653±0.9551), (22.7485±1.0267), (22.1725±0.9939), all P < 0.01], the difference having a statistical signifieance(F=16.131,13.543,26.953,41.583, all P<0.01). Conclusions Iodine deficiency and hypothyroidism during critical periods of brain development may change eerebellar morphology and down regulate the protein expression of ERK1/2, which may result in damage of cerebellum development.

Objective To explore the clinicopathological characteristics of non-muscle-invasive bladder cancer patients association with chronic kidney disease (CKD).Methods Between Jan 2009 and Dec 2010,536 patients (390 males and 146 females with mean age of 63 years) underwent surgical treatment at our institute for pathologically proven non-muscle-invasive bladder cancer.The clinical and pathological data of these patients were reviewed,and the relationships of these factors and CKD were analyzed.Presence of CKD was confirmed in patients with estimated glomerular filtration rate (eGFR)＜ 60ml/(min · 1.73 m2)calculated using the Modification of Diet in Renal Disease Study equation.Results Of the 536 consecutive cases,57 patients (10.6％) had CKD.Compared to the patients without CKD,there were more females and older patients in the patients with CKD (52.6％ vs 24.2％ and 69 years vs 62 years,both P ＜ 0.05).The patients with CKD proned to have multiple bladder tumor (71.9％ vs 50.9％,P ＜ 0.05) and synchronous upper urinary tract urothelial carcinoma (7.0％ vs 2.3％,P ＜0.05).The history of bladder cancer and upper urinary tract urothelial carcinoma were also predominated in these patients (43.9％ vs 29.0％ and 40.4％ vs 6.5％,both P ＜ 0.05).ConclusionConcurrent CKD in non-muscle-invasive bladder cancer patients is associated with greater risk of multiple tumors in urinary tract,particularly in female patients.

Objective To investigate the relationship between the tube voltage and radiation dose as well as image quality in adult upper airway digital radiography (DR).Methods We used CDRAD2.0 contrast details phantom and PMMA to simulate adult upper airway. With different tube voltages,the phantom was exposed using automatic exposure control system (AEC).The entrance surface dose( ESD),dose area product(DAP) and mAs in every exposures were recorded.The image quality factors(IQF) of all images were calculated. Results With tube voltage increasing,ESD,DAP,mAs decreased and IQF value enhanced.There were statistically significance ( F =45.15,26.41,29.26,56.53,P ＜ 0.05 ).ESD,DAP,mAs significantly increased with tube voltage less than 75 kV,began to decrease when tube voltage more than 75 kV,tended to be on the balance in 75 -80 kV.At the same time,the fluctuation of IQF value was no statistical difference in 50 - 75 kV of tube voltage,but was statistical significance in 75 -90 kV( F =11.35,P ＜0.05 ).So,the image quality of adult upper airway with different tube voltage had no significant difference.Conclusions The appropriate tube voltage was 75 kV to 80 kV in the upper airway DR.The IQF value can be provided as the clinical evaluation index of image quality.

Objective To explore the association of genetic polymorphism of fucosyltransferase (FUT) 2 and FUT3 and expression of Lewis antigen with ulcerative colitis (UC) in Chinese Zhejiang Han population.Methods We genotyped FUT2 (rs281377, rs1047781 and rs601338) and FUT3 (rs28362459, rs3745635 and rs3894326) in 485 UC patients and 580 healthy controls using SNaPshot. By immunohistochemistry method, we also evaluated expression of Lewis a and b antigens in the sigmoid colon of 10 UC patients and 10 patients with benign colonic polyps.Results The frequencies of mutant allele (A) and genotype (GA+AA) in FUT3 rs3745635 were higher in UC patients than in controls (P=0.016, 95%CI 1.339-1.699;P=0.038, 95%CI 1.330-1.742, respectively). Stratified analyses revealed that the frequencies of mutant allele (G) and genotype (TG+GG) of FUT3 rs28362459 were significantly lower in patients with extensive colitis than in those with distal colitis (P=0.001, 95%CI 0.567-0.786;P<0.001, 95%CI 0.503-0.742, respectively). Similar conclusions were drawn for the mutant allele (A) and genotype (GA+AA) of FUT3 rs3745635 in patients with extensive colitis compared to those with distal colitis (P=0.011, 95%CI 0.621-0.900;P=0.006, 95%CI 0.553-0.845, respectively). Although expression of Lewis b antigen in the sigmoid colon did not differ between UC patients and controls, Lewis a antigen expression was higher in the crypt epithelium of both inflammatory and non-inflammatory sigmoid colon of UC patients than in controls (P=0.028).Conclusion Polymorphisms of FUT3 and expression level of Lewis a antigen might be associated with UC.
