Objective To identify the sex-related DNA copy number alterations (CNA) in hepatocellular carcinoma (HCC). Methods High-resolution array comparative genomic hybridization Carray- CGH) was used to examine 17 female and 46 male HCCs. Two-tailed Fisher's exact test or χ2 test was used to compare the differences in CNA between females and males. Results The overall frequencies and patterns of CNA in female and male cases were similar. However, female HCC tumors presented more copy number gains compared to male on lq21. 3-q22(76. 5% vs 37. 0%, P = 0. 009), llqll(35. 3% vs 0. 0%, P = 0. 000 2) and 19ql3. 31-ql3. 32(23. 5% vs 0. 0%, P = 0. 004), and more loss on 16pll. 2(35. 3% vs 6. 5%, P = 0. 009). Relative to females, male cases had more copy number loss on llqll(63. 0% vs 17. 6%, P = 0. 002). Further analyses showed that llqll gain was correlated with 19ql3. 31-ql3. 32 gain(P = 0. 042) and 16pll. 2 loss(P = 0. 033), while lq21. 3-q22 gain was correlated with 19ql3. 31-ql3. 32 gain(P = 0. 046). Conclusion Our findings suggest that CNA may play an important role in sex-related difference in HCC development.

OBJECTIVETo detect the expressions of receptor tyrosine kinases (RTKs) mRNA and protein and to explore potentially promising tumor markers and conceivable drug target in bladder cancer.

METHODSThe expressions of RTKs mRNA and protein in tissue from invasive urothelial carcinoma of the bladder were examined by real-time quantitative PCR array and cytokine antibody array, with normal bladder tissue as control. The Results were analyzed using bioinformatic approaches.

RESULTSThe expressions of TGFA, STAB1, SERPINE1, ANGPT2, SPINK5, ANGPTL1, PROK1, MDK, CXCL9, GRN, RUNX1, VEGFA, and TGFB1 were obviously upregulated in bladder cancer tissue, while those of EDIL3, PTN, CCL2, PDGFD, FGF13, KITLG, FGF2, SERPINF1, and TNF were downregulated. ALK, Btk, EphB2, ErbB4, PDGFR-α, ROS, Tie-2, Tyk2, and VEGFR3 were over-expressed in bladder cancer, while FRK, Fyn, IGF-IR, Insulin R, Itk, JAK1, JAK3, and LCK were low-expressed.

CONCLUSIONVascular endothelial growth factor/platelet-derived growth factor-targeted therapies may play an active role in treating carcinoma of bladder.

OBJECTIVETo investigate the effects of small interfering RNA (siRNA) targeting YAP on the proliferation and apoptosis of human periodontal ligament stem cells (hPDLSCs).

METHODSSynthesized sequences of siRNA were transfected into hPDLSCs by Lipofectamine™ 2000. The expression of YAP was identified by using real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. Proliferation activity was detected by using cell counting kit-8 (CCK-8). Changes in the cell cycle and apoptosis rate were detected by using flow cytometry. Results were analyzed by using SPSS 19.0, and P < 0.05 was considered statistically significant.

RESULTSExpression of YAP mRNA and protein were significantly downregulated after 48 h of transfection (P < 0.001). No obvious difference was found in the expression levels of YAP protein between 48 and 72 h, thus indicating that siRNA could inhibit the expression of YAP persistently and effectively. Proliferation activity was inhibited, and apoptosis rate was increased. Cell cycle was changed as the proportion of G₁and S phases increased (P < 0.01) and G₂ phase decreased (P < 0.05).

CONCLUSIONKnocking down YAP gene by siRNA could inhibit proliferation activity, induce apoptosis, and change the cell cycle of hPDLSCs. Thus, YAP could regulate the proliferation and apoptosis of hPDLSCs.

Objective: To observe the effects of acupoint thread-embedding therapy and low-carbohydrate diet therapy on obese patients with food addiction. Methods: Sixty-five eligible patients were randomized into a thread-embedding group of 33 cases and a diet group of 32 cases to respectively receive 12-week treatment. Before treatment, after treatment and at 6-month follow-up, the two groups were observed and compared in terms of body mass (BM), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), body mass index (BMI), body fat rate (BFR), basal metabolic rate (BMR) and Yale food addiction scale version 2.0 (YFAS 2.0). Results: At the end of treatment, there were no significant differences in the general efficacy, and the improvements in BM, BMI, WC, HC, WHR and BFR between the thread-embedding group and diet group (all P>0.05). At follow-up, the thread-embedding group showed more significant improvements in all the aforementioned indicators compared with the diet group except HC (all P<0.05). At the end of treatment and follow-up, BMR and YFSA 2.0 had more significant improvements in the thread-embedding group than in the diet group (all P<0.05). Conclusion: Acupoint thread-embedding therapy can produce significant efficacy in treating obese patients with food addiction; it can improve the food addiction state and work better in maintaining the efficacy compared with low-carbohydrate diet therapy.
