Objective To investigate the relationship between non muscle-invasive bladder can-cer and polymorphisms of DNA repair genes among Han nationality in Shanghai. Methods From January 2006 to June 2008, 94 patients with non muscle-invasive bladder cancer and 304 controls were enrolled. Known single nucleotide polymorphism(SNP) in the XPC, XPG, XRCC1 genes were detec-ted by TaqMan real-time PCR. After adjusted for age, sex, and smoking, interaction effects of the genotypes and non muscle-invasive bladder cancer risk, genotypes and clinical and pathological features of bladder cancer were analyzed using unconditional Logistic regression. Results After adjusted for age, sex, and smoking, the XPC 939 Lys/Gln, XPC 939Gin/Gin genotype and XPG 1104 Asp/His, XPG 1104 His/His genotype were more frequent in patients with non muscle-invasive bladder cancer, adjusted OR=1.89, 95%CI 1.14-3. 23 and OR=1.07,95%CI 0.86-1.87, respectively. The XRCC1 Arg399Gln polymorphisms were not significantly associated with non muscle-invasive bladder cancer, adjusted OR= 1.15, 95% CI 0.55-2.40. There were no significant associations between tumor clinical and pathological features in patients who possessed either the XPC or XPG polymor-phisms (P>0.05). Conclusion XPC Lys939Gln and XPG Asp1104His may modulate non muscle-invasive bladder cancer risk among Han nationality in Shanghai.

OBJECTIVETo explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation.

METHODSThirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared.

RESULTS(1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05).

CONCLUSIONThe electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

AIM: To investigate the cell cycle arrest ind uced by hypoxia, hypoxia inducible factor-1 and their possible mechanism in huma n ovarian cancer cell line SW626. METHODS: CoCl 2, a chemical inducer of hypoxia and hypoxic cell culture chamber were used to induce chemical and physical hypoxia in human ovar ian cancer cell line SW626. The method of ‘decoy’ was used to block the functi on of HIF-1? because it acts as the core sequence of the target gene as a compe titor combined to the HIF-1?. The cells were divided into group A1 (normal oxyg en), A2 (normal oxygen plus HIF-1? decoy), B1 (CoCl 2), B2 (CoCl 2 plus HIF-1 ? decoy), C1 (hypoxia) and C2 (hypoxia plus HIF-1?). The expression of the HIF -1? protein, mRNA and cell cycle analysis were detected by Western blotting, RT -PCR and flow cytometry (FCM). RESULTS: The expression level of HIF-1? protein in group B1 (3 .75?1.31) and group C1 (3.48?1.01) was significantly higher than that in g roup A1 (0.97?0.31) (P0.05). FCM showed that the G 0/ G 1 phase was markedly increased in group B1 (81.78?24.33) and group C1 (77 .62?22.76) and was significantly higher than that in group A1 (49.49?18.54 ) (P0.05). CONCLUSION: Both CoCl 2 and physical hypoxia could distinctly i nduce cell cycle arrest in G 0/G 1 phase and the expression of HIF-1? in huma n ovarian cancer cell line SW626. HIF-1? plays an important role in cell cycle arrest induced by hypoxia in human ovarian cancer cell line SW626.

Objective To test the hypothesis of autophagy that silencing PHD2 gene could increase hypoxia inducible factor (HIF)-1α levels in the renal medulla and attenuate hypoxia injury in cultured human renal proximal tubular epithelial cell (HK-2) under cobalt dichloride (CoCl2) exposure.Methods HK-2 cells were harvested at hour 0,6,12,24,36 and 48 after exposure to CoC12 (200 μmol/L).The role of HIF/PHD pathway in CoCl2-induced cell apoptosis/autophagy was studied by employing small-interfering RNA (siRNA).Dynamic profiles of apoptosis markers (Bax,Bcl-xl) and autophagy marker (LC3) of HK-2 cells within 48 h after exposing to CoCl2 were recorded.Alamar Blue assay was used for quantitative analysis of cellular growth and viability.Electron microscopy analysis was employed to evaluate the changes in autophagic structures.Results The protein expressions of PHD2 were gradually increased after exposing to CoCl2 (200 μmol/L),with statistics significance at 24 h and reached the peak at 48 h (both P ＜ 0.01).PHD2 siRNA reduced PHD2 levels by ＞ 60％ and significantly increased HIF-1α protein levels (P ＜ 0.01),but had little effect on HIF-2α.The protein expression of Bcl-xl was significantly up-regulated,while the level of Bax and LC3-Ⅱ/LC3-Ⅰ were down-regulated in PHD2 siRNA group (all P ＜ 0.01),compared with the negative control group.Meanwhile,either 3-Methyladenine (an autophagy inhibitor) treatment or PHD2 knockdown rescued cell death and increased cell viability through autophagy inactivation.The ratio of LC3-Ⅱ/LC3-Ⅰ and the quantity of autophagosomes were decreased,and the cell ultrastructure was also relatively intacter than the negative control group.Of interest,co-administration of HIF-1α siRNA with PHD2 siRNA abrogated renoprotective effect conveyed by PHD2 siRNA alone,suggesting that activation of endogenous HIF-1α-dependent pathways mediated the autophagy inactivation effects of PHD2 silencing.Conclusions Direct inhibition of PHD2 promotes renal epithelia cell survival against CoCl2-induced cell apoptosis/autophagy.Activation of the HIF-1α signaling pathway is required to reduce apoptosis and autophagy via up-regulating the expression of Bcl-xl protein.

The influence of inner cell mass (ICM) and trophectoderm (TE) score on pregnancy outcomes in frozen-thawed blastocyst transfer cycles was analyzed. A retrospective analysis of 741 cycles of frozen-thawed blastosysts transfer was performed. All cycles were divided into four groups based on the number and morphological score of blastocysts: S-ICM B/TE B group (n=91), the single blastocyst transfer of ICM B and TE B; D-ICM B/TE B group (n=579), double blastocysts transfer of ICM B/TE B; D-ICM B/TE C group (n=35), double blastocysts transfer of ICM B/TE C; and D-ICM C/TE B group (n=36), double blastocysts transfer of TE B/ICM C. The pregnancy outcomes were compared among the four groups. As compared with D-ICM B/TE C group, the clinical pregnancy rate, implantation rate and multiple pregnancy rate were increased in D-ICM B/TE B group (74.96% vs. 57.14%, 57.43% vs. 37.14%, and 48.62% vs. 25%, respectively, P<0.05 for all). Clinical pregnancy rate and implantation rate in D-ICM B/TE B group were also higher than in D-ICM C/TE B group (74.96% vs. 50%, and 57.43% vs. 33.33%, both P<0.05). Multivariable Logistic regression analysis indicated that ICM score was a better predictive parameter for clinical pregnancy (OR=3.05, CI 1.70-5.46, P<0.001), while the trophectoderm score was a better one for early abortion (OR=0.074, CI 0.03-0.19, P<0.001). Clinical pregnancy rate and multiple pregnancy rate in S-ICM B/TE B group were significantly lower than those in D-ICM B/TE B group (46.15% vs. 74.96%, and 2.38% vs. 48.62%, both P<0.05), but there was no significant difference in the implantation rate between the two groups. It was suggested that the higher score of ICM and TE may be indicative of the better pregnancy outcomes. The ICM score is a better predictor of clinical pregnancy than TE, while TE score is a better one in predicting early abortion. Single ICM B/TE B blastocyst transfer in frozen-thawed cycles can also get satisfactory pregnancy outcomes.
