To compare the effects of laparoscopic total or subtotal hysterectomy and myomectomy on ovarian reserve by measuring the serum level of anti-Mullerian hormone (AMH).A total of 96 patients with uterine fibroids underwent total laparoscopic hysterectomy (TLH group,n =32),laparoscopic subtotal hysterectomy (LSH group,n =31) and laparoscopic myomectomy (LM group,n =33).Changes in ovarian reserve were examined by measuring the level of AMH pre-operation and at 1 and 4 months post-operation.No significant differences existed in AMH in LM group[(1.42 ±0.65),(1.31 ±0.53) & (1.33 ±0.61) μg/L,P ＞ 0.05].The levels of AMH in both groups were significantly lower than those at pre-operation [(1.17 ± 0.11),(1.01 ±0.10),(0.48±0.54) & (1.18±0.93),(0.45 ±0.39),(0.14±0.0) μg/L,P＜0.001].The mean percentage decrease in AMH was lower in TLH group than that in LSH group at 4-month follow-up [(-37.4 ± 37.6) ％ vs.(-27.0 ± 23.0) ％,P =0.017].The results showed that LM had no effect on ovarian reserve.Both LSH and TLH had adverse effects on ovarian reserve and TLH was more marked.

Purpose To investigate the expression level and the role of TUSC7 in human cutaneous malignant melanoma (CMM).Methods Quantitative real time-PCR (qRT-PCR) assay was performed to detect the expression of TUSC7 in 60 cases of CMM tissues,20 cases of benign nevus,4 CMM cell lines,and one normal human epidermal melanocytes.Then overexpression of TUSC7 was performed and its role in tumor progression was explored.Results TUSC7 expression was significantly downregulated in primary CMM tissues (n =60) compared to benign nevi (n =20),which were significantly downregulated in all the four melanoma cell lines,especially in A375 cells,compared with the normal melanocytes cells (all P ＜ 0.05).In comparison with the A375 cells transfected with the empty plasmid,those transfected with pcDNA-TUSC7 showed an obvious decrease in the proliferation and colony formation activity,while increase in the apoptosis rate (all P ＜ 0.05).Conclusion Our results suggested that the dysregulation of TUSC7 may play an important role in the CMM progression.

Objective To investigate the role of inflammatory cytokines in the pathogenesis of chronic non-bacterial prostatitis/chronic pelvic pain syndrome (CAP/CPPS) patients. Methods The 38 cases with CAP/CPPS patients (18 cases of CAP and 20 cases of CPPS) and 20 cases of healthy controls were selected. The differential expressions of 40 kinds of inflammatory cytokines were detec-ted by antibody arrays in prostate fluid. Results The inflammatory cytokines which increased more than 1.5 times expression have been found. There were seven kinds in CAP including monocyte che-moattractant protein (MCP)-1, solution tumor necrosis factor receptor Ⅱ(s TNF R Ⅱ), platelet-de-rived growth faetor-BB (PDGF-BB), interleukin (IL)-β, IL-11、IL-6、MCP-2 and five kinds in CPPS groups including MCP-1、PDGF-BB、MCP-2、s TNF R Ⅱ、It-11 respectively, compared with healthy control group. The cluster analysis results showed that protein expression of Monocyte chemoattrac-tant protein 1 (MCP-1)and platelet-derived growth factor BB (PDGF-BB) were significantly increased in CAP (3.47 and 2.07 times) and CPPS (2.25 and 2.19 times) compared with healthy control group and were the final polymerization of inflammatory cytokines. The protein expression of interleukin 1 β (IL-1 β), MCP-1 and soluble tumor necrosis factor Ⅱ (s TNF R Ⅱ) in CAP group was increased more than 1.85,1.55,1.67 times compared with CPPS group. Conclusions Elevated expression of inflammatory cytokines may play an important role in the course of CAP/CPPS disease. The extent of the inflammatory response of CAP was higher than CPPS. The inflammatory factors of MCP-1 and PDGF-BB could serve as a novel diagnostic marker.

Objective To explore the distribution characteristics of TCM syndrome and clinical relevant factors of benign prostatic hyperplasia (BPH).Methods Totally 781 cases of BPH patients were collected. Chi-square test, analysis of rank and inspection were used to detect the distribution characteristics of TCM syndrome. The multiple classification logistic regression was used to analyze related factors.Results BPH 14 kinds of distribution of syndromes were statistically significant (P<0.01). One of the highest incidence is qi deficiency and blood stasis syndrome (24.97%), and lung heat obstruction is the lowest (1.15%). Composite syndromes (529 cases) were more common than single syndrome (252 cases); syndromes of intermingled deficiency and excess (453 cases) were more common than simple excess (169 cases) or deficiency syndromes (159 cases). BPH single syndrome distribution was different in prostate volume, residual urine volume, maximum urine flow rate, and showed no difference in the serum PSA level. 3 logit model was established successfully. It was found that the patients with the features of 50 to 60 years old, the course < 3 years, I-PSS score for 8 to 19 points showed higher positive incidence of excess syndrome than intermingled deficiency and excess syndromes and deficiency syndrome.Conclusion This study reveals the BPH distribution characteristics and clinical related factors, which has guiding significance to improve TCM clinical level.

Objective To evaluate the efficacy and safety of tacrolimus 0.03％ ointment for the treatment of 2-year-old patients with moderate to severe AD.Methods An open-labeled,non-comparative,multi-center study was carried out,which included 59 2-year-old children with moderate to severe AD.All the patients were given topical tacrolimus 0.03％ ointment twice daily for 3 weeks.The evaluation of patients was scheduled at the baseline,1,2,and 3 weeks after the start of treatment.Clinical outcome parameters included the total response rate,eczema area and severity index score (EASI score),the percentage of body surface area (BSA％) affected,physician's global evaluation (PGE),children's dermatology life quality index (CDLQI),visual analog scale (VAS) pruritus score.Safety was assessed based on adverse events reported by patients or observed by the physicians.Results At the end of the treatment,the total response rate was 65.85％ with an EASI score of 4.18,and BSA％ of 16.41％.Of these patients,85.10％ achieved a satisfactory outcome,2.13％ achieved a complete cure,and all achieved an improvement,with no exacerbation observed.The 3-week treatment also resulted in a significant decrease in VAS pruritus score (from 6.80 to 3.21) and CDLQI (frown 7.06 to 2.91).Side effects mainly manifested as temporary burning sensation at the application site,and no severe adverse events associated with tacrolimus were observed.Conclusion Tacrolimus 0.03％ ointment seems safe and effective for the treatment of 2-year-old patients with moderate to severe AD.

Objective To explore the feasibility and safety of early ambulation in patients with acute deep ve-nous thrombosis. Methods The literatures about early ambulation for acute venous thrombosis were collected and the quality of the literature was evaluated by two investigators independently. Results Thirteen published studies were recruited for systematic review,including 10 RCTs and 3 CCTs. The meta-analysis showed that compared with bed rest,early ambulation did not increase the incidence of secondary pulmonary embolism in patients with acute DVT[early activity:22/1408;bed rest:34/1417;RR=0.62,95%CI(0.37,1.03),and the incidence of DVT progression [early activity:48/1523;bed rest:45/1525;RR=0.85,95%CI(0.58,1.24)]. There were no statistically significant differ-ences in mortality,swelling,and pain relief in acute DVT patients. Conclusion Early ambulation did not increase the incidence of thrombus progression and secondary pulmonary embolism in patients with acute DVT compared with bed rest. Besides,early ambulation cannot relieve symptoms of swelling and pain in DVT patients. However,it can relieve the acute pain of DVT patients with moderate to severe pain.

Objective To evaluate the feasibility and safety of endoscopic intraluminal closure of small colon perforation with metal clips in porcine model.Methods A 2 cm full-thickness colon perforation was made in 4 bama mini-pigs.One did not receive local closure as a control, while 3 others underwent closure with bi-and tri-arm clips, one of which received additional fibrin glue injection after closure.Necropsy was done on day 14 after the procedure, and dye leak test, peritoneal fluid bacteria culture and histological examination were performed.During the 2 week observation period, the body temperature and blood leukocytes count were recorded and compared.Results Endoscopic closure of the colon perforation was technically successful in all 3 pigs.The body temperature and blood leukocyte count of these pigs were both lower than those of the control.Necropsy showed that the perforation in control pig was not completely closed and with multiple adhesions around.Perforation complete closure and pathological healing without adhesion were observed in 2 pigs with clip closure only, while adhesion and incomplete pathological healing was detected in the other one with clip closure plus fibrinogen injection (P＜0.05).Conclusion Endoscopic intraluminal closure of a 2 cm colon perforation with metal clips is feasible and safe, while further study is needed to evaluate the effect of combined local fibrinogen injection.

In this research, we compared the visual neuron responses for LGN, A18 and PMLS of old and young cats with extracellular single-neuron recording techniques. We used firing rate vector to characterize information, and response irregularity of cells to evaluate the degeneration of visual characters. Response irregularity is characterized by means of the two coefficients of variation of firing rate vectors: Cv and Cv2. We found that there was no significant change of the response irregularity in LGN areas during the aging process from young to old cats. But in the other two areas, neurons of old cats exhibited significantly larger response irregularity than those of young cats. The result indicated that the information processing function of advanced visual cortex was impaired by aging. This result also provids a reference for the research of the other neuronal system changes during aging process.

Objective To explore the immune mechanism of negative results of immune tests of schistosomiasis japonica pa?tients. Methods Totally 142 schistosomiasis patients(positive stool examinations)of Poyang Lake region were tested by ELI?SA method,and the ROC curve was applied to determine the high and low response of the patients. The levels of cellular immu?nity and cytokines of high and low responders were compared. Results Totally eight schistosomiasis patients were found as low responders. Besides SWAP?IgA(t= -1.588,P > 0.1),the levels of isotype antibodies were significantly lower in the low re?sponders compared with those in the high responders(t = -14.517 to -2.866,all P < 0.05). In the low responders,the propor?tion of CD3+T was increased;and the proportions of CD4+T,CD8+T,CD4+CD25+Treg,and the ratio of CD4+/CD8+ were all de?creased,but all of them were not significant(t = -1.72 to 0.974,all P > 0.05)compared with those in the high responders. The differences of IFN?γ and IL?10 between the high and low responders were both not significant(t= -2.426 to 0.216,all P >0.05). Conclusions There is a significant difference between the high and low responders only in the levels of isotype antibod?ies. One of the reasons of low response in the immune tests is the much lower antibody level after the antigen?antibody compound is completely formulated.

Objective To explore the cut?off value of the indirect haemagglutination test(IHA)method for schistosomiasis japonica diagnosis in different endemic areas. Methods Totally 55 nature villages of the lake?type endemic counties,Yugan and Xinzi,in Poyang Lake Region of Jiangxi Province were chosen as the study fields,and all the villagers over 5 years old were parallelly examined by Kato?Katz method+miracidial hatching test and IHA method. The detection data were analyzed by the correlation analysis,and the threshold values of the IHA method in different endemic areas were decided by the receiver operat?ing characteristic(ROC)curve. Results The positive rate of stool examinations of the villagers was correlated with the distribu?tion trend of the antibody level of whole population(r=0.588,P<0.05),but no correlation with the antibody level of the posi?tive population(r=0.221,P>0.05). The antibody level of stool?negative population during the period of 2008 to 2011 detect?ed by IHA method dropped year by year,and the annual difference was statistically significant(F=3.650,P<0.05). While the antibody level of stool?positive population found during the period of 2008 to 2011 maintained a certain high level in the 4 years,and there was no statistically significant difference among them(F=2.461,P>0.05). When the positive rates were<1%,1%-5%or>5%,the specificity of diagnosis could be improved when 1∶80,1∶20 and 1∶10 were used as the cut?off val? ues of IHA correspondingly. Conclusion The different threshold values for diagnosis of schistosomiasis japonica should be con?sidered while using IHA method to screen out patients in different endemic areas.
