Objective To provide evidence for decision-making on bladder cancer prevention through investigating the main risk factors related to the incidence of bladder cancer in Chinese population.Methods Using the search terms "bladder neoplasm" and "smoking", the literature from January 1979 to June 2005 on the relationship between risk factors and bladder carcinoma was searched from MEDLINE database and PubMed database,and was studied by Meta-analysis.At the same time,ORs of randomized model and fixed model were calculated to evaluate the sensitivity.Results Totally,23 epidemiological studies on risk factors of bladder cancer were analyzed synthetically by Meta-analysis.The cumulative cases and controls were 7 600 and 5 002,respectively.The pooled odds ratio(OR) values and 95% CIs were as follows:smoking,1.38(1.22-1.57);contacting chemicals,1.95(1.74-2.19);drinking alcohol,2.53(1.60-4.00);drinking coffee,1.31(1.04-1.64);family history of bladder cancer,4.43(3.54-5.53);and gender,4.12(3.71-8.14);respectively(P

Objective To investigate the risk factors of complications induced by intraperitoneal chemotherapy after radical resection for colorectal cancer,and to summarize the prevention and treatment methods.Methods The clinical data of 234 colorectal cancer patients who received intraperitoneal chemotherapy after radical resection at the Union Hospital of Fujian Medical University from January 1997 to March 2007 were retrospectively analyzed.Risk factors influencing the incidence of complications were determined by analyzing 12 relevant factors with one-way analysis of variance(ANOVA)and Logistic multivariate regression analysis.Results The incidence of complications after intraperitoneal chemotherapy for colorectal cancer was 37.2%(87/234),incidence of catheter-associated complications was 20.5%(48/234),incidence of adhesive ileus was 12.4%(29/234),and the incidence of chemical peritonitis was 19.2%(45/234).The results of one-way ANOVA and Logistic multivariate regression analysis showed that abdominal surgery history,surgical modality,postoperative complications,courses and frequencies of chemotherapy and chemotherapeutics were the risk factors influencing the incidence of complications after intraperitoneal chemotherapy.Conclusions One or two courses of intraperitoneal chemotherapy after radical resection for colorectal cancer is safe with few complications.Chemical peritonitis is the main cause for adhesive ileus after intraperitoneal chemotherapy,maintaining intestinal tract unobstracted during intraperitoneal chemotherapy is effective in preventing adhesive ileus.

To meet the requirements of military medical readiness and to win in informatized war, striding development of Chinese medical equipment has to be performed. This paper presents related guiding ideology, principle, mission, objective and countermeasures.

Objective To investigate the effect of different instillation methods on recurrence of superficial bladder carcinoma after surgical operation by meta-analysis.Methods Literatures in the relationship between different instillation methods and recurrence of superficial bladder carcinoma issued from January 1989 to February 2005 were retrieved and the effects were quantitatively estimated with fixed-effect model and random-effect model by meta-analysis.Results Forty-three copies of related literatures were included in the analysis.Combined OR of the instillation methods excluding BCG,only BCG instillation and combined instillation of BCG and other drugs for the recurrence of bladder carcinoma after surgical operation was 0.55(95%CI:0.40~0.74),0.32(95%CI:0.06~1.64) and 0.43(95%CI:0.33~0.57),respectively.Funnel plot showed symmetrically distributed studies,indicating little publication bias and reliable conclusions.Conclusions Only BCG instillation and combined instillation of BCG and other drugs could effectively lower recurrence of superficial bladder carcinoma after surgical operation.

Objective To explore the effective treatment in children of abdominal allergicpurpura.Methods To retrospectively analyze the clinical data of 54 children with abdominal allergicpurpura.54 cases were divided into three groups.Each 18 cases in group Ⅰ,groupⅡ,and group Ⅲ.It was used large doses of methylprednisolone in the group Ⅰ,ranitidine in the groupⅡ,and cimetidine in the groupⅢ,based on conventional treatment.To analyze the effect and adverse effect after the treatment.Results The effect of groupⅠ,and groupⅡ,was significantly higher than group Ⅲ(t=11.775,8.901,7.613,5.786,10.105,12.347,all P＜0.05).There was no significant difference between groupⅠ,and group Ⅱ(P＞0.05).The adverse effect of groupⅠ,was significantly higher than the other groups(x2=4.500,5.017,all P＜0.05).Conclusion The treatment of hormone had obvious effect in children with abdominal allergicpurpura,but it had some risks in the gastrointestinal,so we should close observe the gastrointestinal tract in children.Ranitidine and cimetidine are the drugs of inhibiting gastric acid secretion,but the ranitidine much better than cimetidine.

Asthenospermia accounts for about 30% of the causes of male infertility. Currently, most drugs for asthenospermia lack specificity and desirable therapeutic efficiency. An insight into the pathogenesis of asthenospermia is important for the development of specific therapies for this disease. The protein Na+/K(+)- ATPase α4 isoform (NKA4) presents in both mature testis tissue and the sperm tail, the absence or reduced activity of which may significantly decrease sperm motility. Ouabain is a natural inhibitor of NKA4, suppressing its activity by specifically binding the ouabain site in it. The hypothalamus and adrenal cortex excrete an ouabain-like steroid hormone called endogenous ouabain (EO), which may be associated with the pathogenesis of asthenospermia by inhibiting the activity of NKA4, affecting Na+/H+ exchange, Na+/Ca2+ exchange and sperm cell membrane potential, and eventually reducing sperm motility.

Severe burns and trauma can lead to insulin resistance (IR), which is associated with the metabolic disorder and hyperglycemia, and routine insulin treatment yield no noticeable outcome. However, long time big-dose insulin treatment can sometimes cause hypoglycemia, threatening the life of patients and making the condition more complicated to treat. By now, the mechanism of IR is not yet clearly understood. This article reviews the recent researches about the post-receptor signal transduction mechanism of IR after severe burns and its influencing factors.

Objective To investigate the applicative value of transvaginal color doppler sonography com-bined with CA125 which is tumor detection maker in the the diagnosis of ovarian of benign and malignant tumor . Methods We analyzed sonographic features ,blood flow of transvaginal color doppler sonography and serum CA 125 level in 102 ovarian tumor cases and compared with pathological findings and study the sensitivity ,specificity and accuracy of diagnosis.Results The sensitivity,specificity and accuracy of the diagnosis of ovarian of benign and malignant tumor detected by transvaginal color doppler sonography were respectively 80.6%,95.8%and 91.2%. The sensitivity ,specificity and accuracy of the diagnosis of ovarian of benign and malignant tumor detected by tumor makers CA125 were 87.1%,87.3%and 87.3%respectively.The sensitivity,specificity and accuracy of the diag-nosis of ovarian of benign and malignant detected by transvaginal color doppler sonography combined with tumor makers CA125 were 93.5%,97.2%and 96.1%respectively.The sensitivity,specificity and accuracy of results de-tected by the combination of both methods were higher than the single one .Conclusion The combination among the sonographic features ,blood flow of transvaginal color doppler sonography and serum tumor markers CA 125 im-proves the efficiency of ovarian benign and malignant tumor diagnosis ,and therefore shows the great clinical value .
