Expression of KIF18A in gastric cancer and its association with prognosis / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the expression of KIF18A gene protein in gastric cancer tissues and its association with the prognosis of patients.</p><p><b>METHODS</b>Twenty fresh paired gastric cancer specimens and adjacent normal mucosa(at least 5 cm from the edge of tumor) from 20 gastric cancer patients undergoing operation in Department of General Surgery at the First Affiliated Hosptial of Anhui Medical University between March 2015 and July 2015 were collected. Real-time PCR was used to examine KIF18A mRNA expression in above specimens. Meanwhile, paraffin embedded cancer tissue samples from 129 gastric cancer patients undergoing operation and 23 samples of randomly selected normal gastric tissue(adjacent non-cancer tissue) were collected to establish the microarray. Immunohistochemistry method was applied to detect the KIF18A protein expression in the microarray after confirmation by pathologists. Association of KIF18A expression with clinicopathological features in gastric cancer patients was evaluated. Cox proportional hazard model was used to identify prognostic risk factors.</p><p><b>RESULTS</b>Among 20 fresh paired gastric cancer specimens, mRNA expression of KIF18A in 16 specimens was obviously lower than that in adjacent normal tissues. The positive rate of KIF18A protein expression in gastric cancer tissues was significantly lower than that in normal gastric tissues in microarray[45.0%(58/129) vs. 69.6%(16/23), P=0.041]. KIF18A protein expression was significantly associated with invasion depth (P=0.008) and TNM staging (P=0.032). The median overall survival of all the 129 patients was 44.0(95% CI: 39.78-49.24) months. The three-year survival rates of patients with high and low KIF18A expression were 67.2% and 36.6% respectively(P=0.020). Cox regression analysis showed that KIF18A expression was an independent protective factor of the prognosis of gastric cancer patients (HR=0.570, 95% CI:0.335 to 0.970).</p><p><b>CONCLUSIONS</b>KIF18A expression is down-regulated in gastric cancer tissue, which may play a critical role in gastric cancer carcinogenesis. Lower expression of KIF18A is associated with poor prognosis of gastric cancer patients. KIF18A may be a potential prognostic marker of gastric cancer.</p>

Male sexual function after laparosco-pic and laparotomye section in patients with lower rectal cancer / 实用医学杂志

Objective To investigate the effects of laparoscopic and open resection with pelvic autonomic nerve preservation (PANP) on sexual function of male patients with lower rectal cancer. Methods Total 177 male patients with lower rectal cancer received surgery from September 2008 to December 2013 were enrolled into two groups: the laparoscopic PANP group (n = 105) and the open PANP group (n = 72). The classifications of erectile and ejaculatory functions were used to evaluate the sexual functions of patients at 6 months and 12 months post-operation, respectively. The effect of different operation on the sexual function of the male patients was compared between the two groups. Results The incidence rates of erectile dysfunction at 6 months and 12 months post-operation in the laparoscopic group were lower than those in the laparotomy group (P < 0.05). The incidence rates of ejaculatory dysfunction at 6 months and 12 months post-operation in the laparoscopic group were also lower than those in the laparotomy group (P < 0.05). Conclusion The laparoscopic resection with PANP in patients with lower rectal cancer can not only clearly reveal pelvic autonomic nerve and effectively protect them, but also reduce the incidence of postoperative sexual dysfunction.

Clinical study of anti-Mullerian hormone in prediction of ovarian aging / 中华妇产科杂志

Objective To explore the serum anti-Mullerian hormone (AMH) level in women of childbearing age with normal menstrual cycles. Methods A total of 1 423 women with regular menstrual cycles were selected and divided into 5 groups according to their ages, i.e.≤25, 26-30, 31-35, 36-40,≥41 years. Their serum levels of AMH were measured, and the relationship between AMH and age was analyzed. Results The serum AMH levels of 5 groups according to ages (≤25, 26-30, 31-35, 36-40, ≥41 years) were 3.62, 3.10, 2.27, 1.07, 0.45μg/L, respectively. The comparison of serum AMH levels in different age groups had significant difference (P<0.01). Serum AMH level declined with increasing age,and dropped significantly after 36. The serum AMH level and age showed a negative correlation with significant difference (r=-0.374, P<0.01). Quadratic regression of logAMH proximally reflected the relationship between AMH and age. Conclusion AMH determination for women of childbearing age could provide reference for the evaluation of ovarian function.

The expression of THBS2 and its correlation with prognosis in gastric cancer / 安徽医科大学学报

Objective To explore the expression of THBS 2 and its clinical significance in gastric cancer . Methods The mRNA and protein expression levels of THBS2 were assessed in 14 paired of gastric cancer specimen and corre-sponding normal mucosa using quantitative real-time PCR and Western blot analysis. Immunohistochemistry of TH-BS2 on a population-based tissue microarray consisting of 129 gastric cancer cases was used for evaluating the TH-BS2 prognostic significance. Kaplan-Meier method and Cox′s proportional hazards model were used in survival anal-ysis. Results Both mRNA and protein expression of THBS2 in 12 gastric cancer tissues were remarkably lower than the corresponding normal tissues among total 14 pair tissues. Consistent with the results of our Western blot, THBS2 expression was significantly inhibited in gastric cancer tissues as that in the normal controls in TMA ( P=0. 031) . Overexpression of THBS2 had a significant correlation with favorable prognosis of gastric cancer patients ( P=0. 002 ) and decreasing THBS2 expression was associated with the poor histological grade of gastric cancer his-tological grade ( P=0. 005 ) . Conclusion This study suggests THBS2 is down-regulation in gastric cancer tissue versus normal gastric tissue, and it may play a critical role in gastric cancer carcinogenesis and may be a potential prognosis predictor of gastric cancer.
