Objective:The objective of this research is to study the serum level of the high-mobility group protein B1 (HMGB1) in human ovarian tumor (OvCa) and in a healthy control. This study also aims to identify different HMGB1 levels before and after sur-gery and to explore the inhibitory effect of HMGB1 gene silencing in the proliferation and invasion ability of OvCa. Methods: En-zyme-linked immunosorbent assay was used to measure the serum level of HMGB1 in OvCa patients and healthy subjects. Lentivirus vector with HMGB1 shRNA was constructed and used to infect OvCa cells. The expressions of HMGB1 mRNA and protein were test-ed by real-time PCR and Western blot. Cell proliferation was detected using the Cell Counting Kit-8 assay, whereas cell invasion and migration were detected by Transwell assay. Results:The serum level of HMGB1 was more elevated in patients with malignant diseas-es compared with individuals with benign diseases and the control groups. In the malignant group, the serum level of HMGB1 de-creased noticeably after therapy. Down-regulation of HMGB1 expression resulted in the inhibition of the biological behavior and metas-tasis of ovarian cancer cells. Conclusion: HMGB1 is closely associated with clinicopathologic features of OvCa. Knockdown of HMGB1 expression can significantly inhibit cell proliferation, cell migration, and cell invasion of OvCa. These findings indicate that HMGB1 can function as a therapeutic target for ovarian neoplasm in the future.

Objective: This research explores the relationship between the immuno-suppression function of regulatory T cells (Treg) in the ascites of ovarian cancer (OC) patients, the clinico-pathologic features of these patients, and the correlation of the function of Treg with initial treatment and relapse status of the patients to further investigate the specific mechanism of immuno-regulatory func-tion of CD4+ CD25+ Treg in the ascites of OC. Methods: Immuno-magnetic activated cell sorting (MACS) was conducted to sort CD4+CD25+Treg and autologous CD4+CD25-Treg from the ascites of 28 OC patients. Carboxyfluorescein-diacetate succinimidyl ester (CFSE) was used to label the autologous CD4+CD25-Treg. These labeled cells were then used as controls and co-cultured with autologous CD4+CD25+Treg at the ratio of 1∶1 or 1∶2. The mean inhibition ratio of Treg in specimens to the proliferation of autolo-gous CD4+ CD25-Treg was calculated after the flow cytometry of the CFSE expression and Modfit software analysis of the CD4+CD25-Treg proliferation index (PI) were performed. Anti-IL-10 and/or anti-TGF-β1 antibodies were neutralized to investigate whether the CD4+CD25+Treg-mediated immuno-suppression escaped through the ascites can produce a marked effect by the inhibitory cyto-kine IL-10 or TGF-β1. Results: The mean inhibition ratio of CD4+ CD25- Treg in the ascites of stage Ⅲ to Ⅳ OC patients was (75.72±17.04)%, which is significantly higher than that of stageⅠtoⅡOC patients (59.61±16.97)%;P<0.05. In addition, Treg in the as-cites of OC patients with recurrent disease showed a significantly higher inhibition ratio than that of patients with primary disease;P<0.001. Moreover, Treg in groups added into neutralizing anti-IL-10 and/or anti-TGF-β1 antibodies displayed significantly lower depres-sant effect than the control group;P<0.05. Conclusion:The immuno-suppression of CD4+CD25+Treg in the ascites of OC patients is correlated with the tumor staging and status of the primary or recurrent diseases. Moreover, Treg may indicate a suppressor function by secreting cytokine IL-10 and TGF-β1.

Objectives:To observe the effect of metabolic intervention of anti TNF antibody on the hypermetabolism occurred in intra abdominal infection(IAI) complicated by multiple organ dysfunction syndrome(MODS). Methods:Twenty rabbits were operated on with cecal ligation plus puncture(CLP) inducing IAI and MODS and were randomly divided into two groups, one receiving the anti TNF serum raised against TNF ?(anti TNF group) at 0.5?h after CLP and another receiving the non specific serum (control group). All animals were placed in metabolic cages and maintained with intravenous infusion for the observation period of one week. Serum levels of cytokines(TNF, IL 6), hormones (cortisol, insulin, glucagon), biochemical indexes (glucose, cholesterol, triglyceride, albumin) and daily excretions of urea nitrogen (UN),creatinine (Cr) and 3 methylhistidine (3 MH) were dynamically determined for 7 days. The death of animals was also recorded. Results:Compared with the control group, the levels of serum TNF, IL 6 and cortisol were significantly decreased and the levels of insulin and glucagon were kept normal after the injection of immune serum in anti TNF group, with significant improvements of biochemical indexes and decreased excretions of UN, Cr and 3 MH in urine. The survival rate was significantly increased in the anti TNF group. Conclusions:The anti TNF antibody can attenuate the metabolic abnormalities of IAI and MODS, being of the metabolic intervention on the hypermetabolism.

Objective To evaluate the activation of premotor area (PMA) in verb generation task, and to discuss the possible function of PMA in language expression. Methods Block-designed fMRI with verb generation task was performed on 23 subjects with GE 1.5T MR Scanner. During the test, the subjects were asked to generate a verb based on a given noun word. The white + appeared on the center of the black screen was used as control. The fMRI data were processed with SPM 2. Group analysis was performed with single sample t-test. Average mapping was obtained and overlapped onto standard MNI template. Activation of the PMA was analyzed. Results The fMRI data of eleven subjects were selected for group analysis after head motion effect was ruled out. Average mapping showed activation in the Broca's area, posterior part of the right inferior frontal gyrus, bilateral PMA and supplemental areas (SMA), left posterior parietal cortex, right thalamus, left basal ganglions, right cerebellum, and posterior part of the right temporal lobe. The area with the greatest activated intensity in the brain was the left PMA. Conclusion PMC is important in verb generation and may be responsible for voice processing, motor imagery, word extracting as well as advanced regulation of information.

Objective To investigate the change of indications of emergency obstetric hysterectomy and the clinical application of intraoperative interventions. And to provide evidence for prevention of hysterectomy and improvement of obstetric quality. Methods Clinical data were collected from 97 patients who received emergency obstetric hysterectomy at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. The patients were divided into two groups by the time point of January 1st, 2009: the first group was cases treated between January 1st, 2004 and December 31st, 2008, while the second group was cases treated between January 1st, 2009 and December 31st, 2013. The clinical indicators, surgical indications, intraoperative interventions, and blood loss between the two groups were analyzed retrospectively. Results (1) Incidence:54 857 women delivered at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. Of them, 97 patients received emergency obstetric hysterectomy, with an incidence of 0.177% (97/54 857). (2) The 17 patients delivered vaginally (18%,17/97) and 80 by caesarean section (83%,80/97). Forty-nine patients experienced repregnancy with scar uterus (51%, 49/97). About 41 patients underwent abdominal total hysterectomy (42%,41/97) and 56 received subtotal hysterectomy (58%,56/97). (3) The number of patients were comparable between the two groups (50 vs 47;P>0.05). (4) The main surgical indication was uterine inertia (45%, 44/97). The main causes of uterine inertia were excessive uterine tension (45%, 20/44) and placental abruption due to gestational hypertension (32%, 14/44). Of all the indications, 29 patients in the first group (58%, 29/50) and 15 patients in the second group (32%, 15/47) suffered from postpartum hemorrhage. Pathological placenta embedment occurred in 15 patients in the first group (30%, 15/50) and 25 patients in the second group (53%, 25/47). The incidences of postpartum hemorrhage due to uterine inertia or pathological placenta embedment were significantly different between the two groups (both P<0.05), respectively. (5) In the first group, the average preoperative blood loss was (2 900±1 900) ml, and the average intraoperative amount of infused white&red blood cells was (5.9±3.5) U, with the average operation time of (2.2 ± 1.8) hours and the average in-hospital duration of (7.8 ± 2.3) days. In the second group, the average preoperative blood loss was (3 100± 2 200) ml, and the intraoperative amount of infused white&red blood cells was (6.2± 5.2) U, with the average operation time of (2.5± 2.1) hours and the average in-hospital duration of (7.9 ± 2.9) days. There was no significant difference between the two groups in any of these indicators (P>0.05). Postpartum hemorrhage was usually treated with uterine packing in the first group, but was preferentially treated with potent uterine contraction agents, arterial ligation, uterine balloon compression or B-Lynch suture in the second group. The therapeutic effects of these new treatments were significantly better than uterine packing (P<0.05). Conclusions The incidence of emergency obstetric hysterectomy did not change significantly in the past decade. However, the indications and intraoperative interventions have changed significantly in the second five years compared with the first five years. The main surgical indications were uterine inertia and postpartum hemorrhage due to pathological placenta embedment. Therefore, strict control of caesarean section indications was important to reduce emergency obstetric hysterectomy.

Objective:CD4+CD25+regulatory T cells (Treg) may contribute to tumor progression by suppressing antitumor im-munity. The function of Treg in antitumor immunity regulation in the peritoneal microenvironment of ovarian cancer (OC) was investi-gated and compared with the circulating Treg to elucidate OC immune escape. Methods: Flow cytometry was used to determine the proportion of CD4+CD25+T cells in CD4+T cells in ascites of 27 patients with OC and in peripheral blood lymphocytes of 28 patients with OC. The samples were analyzed and classified in three stages:primary disease (PD), after chemotherapy (AC), and recurrence dis-ease (RD), according to the clinical conditions of the OC patients upon donating the samples. The percentage of Treg in the three groups was determined in ascites and blood. CD4+CD25+T cells were isolated from ascites and peripheral blood of patients with OC us-ing magnetic sorting (MACS) system. The cells were then tested for regulatory function through coculture with carboxyfluorescein diac-etate succinimidyl ester-labeled autologous CD4+ CD25- responder cells. Results:The proportion of CD4+ CD25+T cells in CD4+T cells significantly increased in ascites (28.25%± 14.06%) compared with that in blood (14.6%± 4.74%;P<0.0001). The Treg in ascites and blood in AC showed higher proportion (P<0.0001) than those in the PD and RD;the proportion in RD was higher than that in PD (P<0.0001). Moreover, the Treg in ascites mediated a significantly higher suppression compared with the Treg in peripheral blood (P<0.001). Conclusion:The frequency and suppressor function of Treg were significantly higher in ascites than in peripheral blood. This finding suggests more possibility for escape immune surveillance in the peritoneal microenvironment. Moreover, the proportion of Treg in AC was higher than that in PD or RD;the proportion in RD was higher than that in the PD. Chemotherapy may favor the expansion of Treg, which may promote the recurrence of cancer.
