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.

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 explore the possible effects of nutritional supplements on brain function as reflected by Water Maze test performance in mice after +Gz exposure.Method Mice were arranged into control group (group A),+Gz group without nutritional supplementation (group B) and +Gz plus nutritional supplementation group (group C).Each group contains 12 mice.Mice in group A were not exposed to +Gz while mice in both group B and group C were exposed to 8 min +10 Gz.Distilled water was gavaged to group B mice 3 h before +Gz exposure.On the day before +Gz exposure pyridoxol fortified water was given and 3 h before exposure mixed amino acids solution were gavaged to group C mice.Water Maze test was done and scores were recorded in all groups.After the Water Maze test was completed,blood was collected through the eyes for serum amino acid determinations and brain tissue was collected by decollation for monoamine determination and γ-glutamyl transferase (GGT) activity evaluation. Result After +Gz exposure,longer completion time and more mistakes were observed in Water Maze test in group B as compared with group A and a trend of improvement in group C was noticed. The ratio of brain 5-HT to dopamine(DA) was significantly reduced in group C as compared with group B.Gamma glutamyl transferase (GGT) activity in brain tissue in group C and group B increased significantly. Conclusion High sustained +Gz exposure significantly reduces Water Maze test performance in mice (longer completion time and more mistakes).It seems that there is a trend of improvement in Water Maze performance in mice in dietary nutritional supplementation group,which might be due to significant reduction in ratio of brain 5-HT to DA in mice with nutritional supplementation.

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.

Objective To analyze the association of Crohn's disease(CD)with vitamin D receptor(VDR) gene polymorphisms. Methods After collecting 326 CD patients and 464 healthy controls,the four single nucleotide polymorphisms of VDR (FokI, BsmI, ApaI and TaqI) were examined by a SNaPshot technique. Results Compared with those in controls,the frequencies of mutant allele(A)and genotype(GA+AA)of BsmI were significantly decreased in CD patients(both P=0.001). The similar conclusions were also drawn for the mutant allele(C)and genotype(TC+CC)of TaqI(both P<0.05). In further stratified analysis,compared with those in controls,the mutant alleles and genotypes of BsmI and TaqI were significantly reduced in stenotic type CD patients (all P<0.0083). The analyses of linkage disequilibrium(LD)and haplotype showed that BsmI,ApaI and TaqI were in a strong LD,and the formed haplotype AAC was significantly lower in CD patients than that in controls (P <0.05). Conclusions VDR(BsmI and TaqI)polymorphisms are significantly related with the reduced susceptibility to CD,especially for patients with stenotic CD. Moreover,the haplotype AAC might engender a reduced risk of CD.

Objective:To explore the central neurobiological mechanisms of pleasure effect on rats with neuralgia treated by tuina manipulations of An-pressing and Rou-kneading Huantiao (GB 30).Methods:A total of 64 male Sprague-Dawley (SD) rats were used in this study.Eighteen rats were randomly selected as a normal group,and the other 46 rats were used to duplicate the chronic constriction injury (CCI) model.Ten rats failed in modeling and 36 rats succeeded.These 36 rats were then randomly divided into a model group and a tuina group,with 18 rats in each group.The rats in the normal group and the model group did not receive any interventions,while those in the tuina group received An-pressing and Rou-kneading Huantiao (GB 30),1 min for each time,once a day,3 weeks in total.Heating tests were evaluated to observe the change of pain-sensitivity score before intervention,1 week after intervention,2 weeks after intervention,and 3 weeks after intervention.After 1 week of intervention,2 weeks of intervention,and 3 weeks of intervention,6 rats were randomly selected from each group respectively for brain extraction.The change of Nissl's body and β-endorphin in the accumbens nucleus as well as amygdaloid nucleus of pleasure circuits,and pro-opiomelanocortin (POMC) in the arcuate nucleus were analyzed by methods of histochemistry and molecular biology.Results:After modeling,the pain-sensitivity scores of the tuina group and the model group were statistically different from the score of the normal group (both P＜0.05).After An-pressing and Rou-kneading Huantiao (GB 30) for one week,the pain-sensitivity score of the tuina group had statistical difference compared with that of the model group (P＜0.05).At each different time point:the amounts of Nissl's body in accumbens nucleus and amygdaloid nucleus of the tuina group were significantly more than those of the model group (all P＜0.01).Besides,the numbers of β-endorphin immunoreactive cells in the accumbens nucleus and amygdaloid nucleus of the rats in the tuina group were significantly higher than those in the model group (all P＜0.01),and so was the expression of POMC in arcuate nucleus (all P＜0.01).Conclusion:An-pressing and Rou-kneading Huantiao (GB 30),where the sciatic nerve is ligated,can reduce pain-sensitivity score and increase pain tolerance value of rats with chronic neuralgia.It can increase the activity of neurons in accumbens nucleus and amygdaloid nucleus of pleasure circuits,which indicates that the analgesia effect of tuina therapy may correlate with pleasure effect,and also reveals a part of neurobiological mechanisms of neuralgia.

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.
