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.

Objective To investigate the surgical indicatin and outcome of recurrent gastric carcinoma.Methods Review the clinical data of 56 cases with recurrent gastric carcinoma underwent reoperation from 1990 to 2000.The operative indication, surgical method and complications were analized.Results In 25 cases the recurrent tumor were resected (44.6%),in 10 cases adjacent organs were resected.NO operative motality was observed.Conclusions More aggressive radical resection of the gastric cancer is the key to prevent recurrence.Laparotomy should be performed without delay once there is a suspicion of recurrence.

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 explore the curative effect of percutaneous cavity injection for the treatment of drug resistant pulmonary tuberculosis guided by color Doppler ultrasound.Methods Ninety-six bacterial culture positive patients with drug resistant pulmonary tuberculosis were randomly divided into treatment group(n =48) and control group (n =48).Patients in both groupswere given systemic anti tuberculosis therapy,and those who in the treatment group were given extra percutaneous cavity injection guided by color Doppler ultrasound.Results After 3 months of treatment,the sputum negative conversation rate,X-ray absorption rate,cavity closure rate,and cavity efficiency rate of the treatment group were 56.3％ (27/48),81.3％ (39/48),58.3％ (28/48) and 75.0％ (36/48) respectively,higher than those of the control group 35.4％ (17/48),62.5％ (30/48),37.5％ (18/48) and 50.0％ (24/48) respectively),and the differences were statistically significant(x2 =4.20,P =0.02 4 ; x2 =4.17,P =0.041; x2 =9.58,P =0.004 ; x2 =6.40,P=0.020).After 12 months of treatment,the sputum negative conversation rate,cavity closure rate,cavity efficiency rate of the treatment group were 93.8％ (45/48),83.3％ (40/48),95.8％ (46/48) respectively,higher than those of control group(77.1％ (37/48),62.5％ (30/48) and 81.3％ (39/48)),and there were significant differences between two groups (x2 =5.35,5.27,5.03 ; P =0.040,0.038,0.025) ; the X-ray absorption rate of the treatment group was 93.8％ (45/48),higher than that of ciontrol group (83.3％ (40/48)),but there was no significant difference between two groups(x2 =2.56,P =0.199).Conclusion It is very effective to treat drug resistant pulmonary tuberculosis using percutaneous cavity injection guided by Color Doppler Ultrasound.No obvious complications or adverse reactions have been observed so far.

Objective:To investigate the role of macrophage migration inhibitory factor (MIF) in severe acute pancreatitis (SAP) associated lung injury in mice.Methods:Totally 32 mice were randomly divided into 4 groups ( n=8/per group): wild type control group (WT+CON group), wild type SAP group (WT+SAP group), MIF gene knockout control group (KO+CON group), and MIF gene knockout SAP group (KO+SAP group). SAP model was established by intraperitoneal injection of L-arginine (4 mg/g). The expression of serum amylase, IL-6, TNF-α and MIF were detected by ELISA. The pathological changes of pancreatic and lung tissues were observed by HE staining. The expression of IL-6 and TNF-α in lung tissue was detected by immunohistochemistry. The expression of NF-κB in lung tissue was detected by Western blot. For measurement data, t test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. Results:Compared with the WT+CON group, pathological score of pancreatic and lung injury, serum amylase, TNF-α and IL-6 expression in serum and lung tissues were significantly increased in the WT+SAP group ( P<0.05), while the above indexes were significantly decreased in the KO+SAP group ( P<0.05). In addition, the expression of NF-κB protein in KO+SAP group was significantly lower than that in the WT+SAP group ( P<0.05). Conclusions:MIF gene knockout can alleviate severe acute pancreatitis associated acute lung injury in mice, and its mechanism may be related to NF-κB.

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.
