Objective To explore more effective methods in vaginal tightening surgery for vaginal relaxation treatment. Methods 132 cases of patients who suffered the decline in quality of sex life owing to vaginal relaxation, requiring improved vaginal tightening surgery. The vaginal surgery was performed to repair the muscles and fascia of the anterior and posterior walls effectively, meanwhile the perineal laceration was also repaired. According to the hammock theory of the treatment of urethral disruption, patients with urinary incontinence with tension was treated to strengthen one suture needle on muscle fascia in the middle of urethra, when repairing anterior of vagina. For patients with constipation, the posterior of vagina was repaired to strengthen 3 suture needles on levator ani during repairing the anterior and posterior wall, so that the vaginal mucosa could get maximum protection. Results 118 patients had been followed up for 2-7 years. A questionnaire survey was conducted about four elements targeted on improving sexual satisfaction, tension incontinence, constipation and vaginal discharge. The clinical results were satisfactory. Conclusions The surgical design is professional and highly effective, and the patients are satisfied with the results. It is suitable for experienced specialists to perform the procedures.

The outcome of diffuse.Large B-cell lymphoma (DLBCL) has been improved in the last decades and will be raised further with the development of novel agents in the future.Personalized treatment for DLBCL is based on its molecular heterogeneity.Except for concurrent translocation of myc and bcl-2,neither clinical nor biological factor is sufficiently available to be used to guide the deviation of R-CHOP therapy in DLBCL.Gene expression profiling and whole genomic analytic techniques are expected to be important approaches at present to determine personalized treatment for DLBCL.The advance in the field being reported by Laurie H.Sehn from University of British Columbia in the 54 ASH meeting was summarized in the paper.

Objective To determine the relationship between normal weight obesity (NOW) and cardiovascular risk factors.MethodsA total of 940 adults who received a health examination in out hospital were recruited in a cross-sectional study,and 407 with a body mass index (BMI) of18.5 to 25 kg/m2were enrolled for further analysis.Body fat percentage ( BF％ ) was measured by bioelectrical impedance analysis (BIA),and the subjects were assigned to the NOW group ( BF％ ≥25％ for male or BF％ ≥35％for female) or the control group ( BF％ ＜ 25％ for male or BF％ ＜ 35％ for female).Cardiovascular risk factors and their detection rates were compared between the two groups by using independent sample t test and x2 test.The correlationbetweenNOW and cardiovascular risk factors was assessedbylogistic regression.Results The prevalence of NOW in men and women were13.1％ and14.9％,respectively.The prevalence of NOW was increased with age ( x2 =6.90,P ＜0.05 ).Systolic blood pressure (SBP),diastolic blood pressure ( DBP ),total cholesterol ( TC ),triglycerides ( TG ),low-density lipoprotein cholesterol ( LDL-C) and serum uric acid (SUA) were significantly increased in the NOW group (t values were 2.97,2.44,2.54,5.09,2.71and 3.91,respectively; all P ＜ 0.05 ) ; whereas high-density lipoprotein cholesterol ( HDL-C) was significantly decreased in the NOW group (t =-3.90,P ＜ 0.05 ).The prevalence of hypertension,hyperglycemia,high triglyceride,low HDL-C,dyslipidmia and hyperuricemia was increased in the NOW group in comparison with the control group ( x2 values were 6.76,5.58,14.50,11.97,10.97 and 8.76,respectively;allP＜ 0.05 ).LogisticregressionshowedNOWincreasedtheriskof hypertension,hyperglycemia,dyslipidmia or hyperuricemia by 2.186,2.120,2.088 or 4.175 times.After adjustment for age and gender,the risk for hyperuricemia was decreased to 3.491,but remained statistically significant higher.Conclusions NOW may be correlated with cardiovascular risk factors,and those with NOW could be at higher risk for cardiovascular diseases.

Objective To discuss the relationship between hepatitis B virus (HBV) genotype and HBV DNA ,liver fibrosis ,liver function and HBeAg .Methods HBV genotypes ,HBV DNA ,liver fibrosis indicators and alanine aminotransferase(ALT ) ,aspartate aminotransferase(AST ) ,total bilirubin(TBIL) ,albumin(ALB) and HBV e antigen(HBeAg) were detected in patients with serum hepatitis .All data were statistically analyzed .Results There was no significant difference of HBV DNA ,ALT ,AST ,TBIL ,ALB , procollagen- Ⅲ -peptide ,type Ⅳ collagen ,hyaluronic acid and laminin between patients with B and C genotype infection (P> 0 .05) . However ,HBeAg level in patients with C genotype infection was higher than that in patients with B genotype infection (P< 0 .05) . Conclusion There might be no significant difference of HBV DNA ,liver function and liver fibrosis between patients with B and C genotype infection ,but HBeAg level in patients with C genotype infection could be higher than patients with B genotype infection .

Objective To investigate the effects of desflurane on the delayed rectifier potassium current (Ik ) in acutely dissociated rat parietal cortical neurons. Methods Wistar rats between 10- and 14-day old of both sexes were used. The parietal cortical neurons were acutely dissociated enzymatically. The extracellular fluid saturated with 0.3,0.6 and 0.9 mmol/L desflurane was added to the culture dish, then the effects of different concentrations of desflurane on Ik were investigated by using the whole-cell patch-clamp technique in acutely dissociated rat parietal cortical neurons. Results IK was inhibited by desflurane in a concentration-dependent manner ( P ＜0.01). The V1/2 of the activation and inactivation curves and the slop factor had no change after giving 0.6 mmol/L desflurane (P ＞ 0.05). Conclusion Desflurane inhibits delayed rectifier potassium channels of parietal cortical neurons of rats in a concentration-dependent manner, and has no effect on the activation and inactivation of delayed rectifier potassium channels, indicating that the change in the excitability of the channel is not involved in the mechanism of inhibitory effect of desflurane, and the other reasons may be involved in the mechanism.

Objective To explore the effects of different dose rates of X-ray under the same dose on cell clonogenic formation in non-small-cell lung cancer cell line A549 in order to provide experimental basis for clinical radiotherapy plan. Methods The A549 cells were cultured at low density and irradiated with X-rays at dose of 4 Gy and selected dose rates of 1, 2, 4 and 6 Gy/min, respectively, from a linear accelerator. The 8th day after irradiation, the cells were fixed and stained with Giemsa solution, and colonies containing at least 50 cells were counted. The plating efficiency and surviving fraction were calculated. Results The clonogenic number in non-irradiated cells was 88.6±4.6. The numbers were significantly reduced in irradiated cells at dose rate 1, 2, 4 and 6 Gy/min (12.3±3.4, 9.0±0.8, 5.6±1.0, 11.5±1.7, respectively) than that in non-irradiated control cells (F=678.799, P<0.05). The plating efficiencies were decreased in irradiated cells, especially in 4 Gy/min irradiated cells, which was lower than that in any of the other three dose rate groups (P< 0.05). Conclusions Though at same radiation dose, cancer cells have different clonogenic formation efficiency when irradiation with X-ray at different dose rates. Thus, treatment with optimal dose rate may improve the radiotherapy efficacy.

Objective To analyze the changes of serum levels ofαII-spectrin breakdown products (SBDPs)in traumatic brain inj ury (TBI)patients,and further to investigate the clinical diagnosis value of SBDPs for patients with TBI,especially with mTBI.Methods The serum levels of SBDPs were examined in 43 severe TBI (sTBI)patients,43 mild TBI (mTBI)patients and 43 healthy controls using enzyme linked immunosorbent assay (ELISA).The diagnostic usefulness of SBDPs for TBI patients were assessed by Receiver Operating Characteristic (ROC)curves analysis.Results There was no significant difference of SBDP145 among the three groups (F=1.340,P>0.05).Serum levels of SBDP120 in controls,mTBI and con-trols were 7.06±2.23,11.67±9.14 and 12.64±11.44 ng/ml,respectively.Compared with controls,serum levels of SB-DP120 were significantly higher in patients with sTBI (F=9.873,P=0.001)and mTBI (F=9.873,P=0.008),while there was no significant difference of SBDP120 between sTBI patients and mTBI patients (F=9.873,P=0.515>0.05). The area under ROC curve (AUC)of SBDP120 for TBI patients was 0.781 (95% CI:0.690~0.872,P<0.001).For mTBI patients,the area under ROC curve was 0.736 (95% CI:0.624~0.848,P<0.001).And for discriminating TBI patients with CT negative or positive,the area under ROC curve was 0.709 (95% CI:0.582~0.837,P=0.007<0.01).Conclusion The serum levels of SBDP120 were significantly increased in TBI patients,especially mTBI patients.And the serum levels of SBDP120 can be used as potential non-invasive biomarker for mTBI patients.

Objective To detect altered levels and clinical significance of serum miR-216a and prognosis monitoring in acute pancreatitis (AP) patients.Methods Serum miR-216a levels were determined by quantitative reverse-transcription PCR (qRT-PCR) assay among 80 mild acute pancreatitis (MAP) patients,80 severe acute pancreatitis (SAP) patients and 74 healthy controls.And amylase (AMY),lipase (LPS),Ca2+,glucose (Glu),hematocrit (HCT),triglyceride (TG),total cholesterol (TC) and C reactive protein (CRP) were measured by biochemical analyzer.The clinical usefulness of miR-216a for AP patients was assessed by ROC curve analysis and correlation analysis.Results Compared with healthy controls (11.12 × 10-5 [5.83 × 10-5,19.12 × 10-5],the serum miR216a levels were significantly increased in AP patients(38.49 × 10-5 [24.05 × 10-5,62.02 × 10-5],(U =-9.10,P ＜ 0.01) . The serum miR-216a levels in MAP and SAP patients were (36.46 × 10-5 [22.29 × 10-5,55.80 × 10-5] vs 40.44 × 10-5 [25.84 × 10-5,65.48 × 10-5]),there was no significant difference between MAP and SAP patients (U =-0.96,P ＞ 0.05).The areas under ROC curve (AUCROC) of miR-216a for differential healthy controls and AP patients was 0.870 (95％ CI:0.825-0.915),cut-off value is 0.61.AUCROC of miR-216a for differential healthy controls and MAP patients was 0.865 (95％ CI:0.808-0.921),cut-off value is 0.59.And AUCROC of miR-216a for differential healthy controls and SAP patients was 0.876 (95％ CI:0.822-0.930),cut-off value is 0.66.Moreover,after the clinical improvement of the patients,the levels of serum miR-216a were significantly lowered from (41.88 × 10-5 [24.24 × 10-s,64.44 × 10-5]) to (20.58 × 10-5 [11.01 × 10-5,41.91 × 10-5]),the differences was significant(U =5.24,P ＜ 0.0l).Correlation analysis showed that miR-216a was positively correlated with CRP (r =0.215,P =0.006) in AP patients.Conclusion The levels of miR-216a in serum of AP patients were increased,which is a potential biomarker for the diagnosis and prognosis monitoring of AP.
