Objective To investigate the effect of electrovaporization on prostatic tissue structure in vivo. Methods 26 cases of benign prostatic hyperplasia underwent electrovaporization of prostatic tissue,the surface area of the vaporized prostatic tissue and the depth at the central area being observed with light microscope and electron microscope. Results The vaporizing effect on tissue with pure cut current were stronger than that with pure coagulative current, the greater the output power the stronger the vaporizing effect.6 millimeter under the vaporized surface caused by pure coagulative current still revealed some histological alterations of injury,while these histological alterations in pure cut current electrovaporization was less. Conclusions These findings may have implications that in transurethral electrovaporization of prostate,injury to the adjacent or deep tissues should be avoided as much as possible.

Objective To study the level of serum high-sensitive C-reactive protein and HbA1c in diabetes patients with blood stasis syndrome,and to investigate the relationship among them.Methods 58 cases of diabetes patients with blood stasis syndrome and 65 cases without blood stasis syndrome were observed.The level of FPG,hsCRP,HbA1c,24 h UAER,TC,TG,HDL-C and LDL-C were estimated.Results The level of FPG,LDL-C,TG,HbA1c,hsCRP of diabetes with blood stasis syndrome were higher than the control group(P 0.05).In patients with blood stasis syndrome,the hsCRP was positively correlated to HbA1c,24 h UAER,BMI,LDL-C,TC,TG,but the multifactor regression analysis indicated that hsCRP was only correlated to the HbA1c independently.Conclusions The long-term hyperglycemia and inflammatory may be one of the reasons for the formation of blood stasis syndrome of diabetes patients,hsCRP and HbA1c may be new evidences for diagnosis of diabetes patients with blood stasis syndrome.

Objective To explore the expression and clinical significance of EphA2 and E-eadherin in colorectal carcinoma.Methods The expression of EphA2 and E-eadherin in 67 cases of eoloreetal carcinoma and 28 cases of normal large intestine tissues were determined by immunohistochemieal method(S-P method),and their relationship to elinicopathological characteristics were analyzed.Results The positive expression of EphA2 and negative expression of E-cadherin in colorectul carcinoma tissues were significantly higher than those in normal intestine tissues(P<0.01).F111e positive expression of EphA2 and negative expression of E-eadherin were positively correlated with tumor histological grade,invasive depth and lymph node metastasis(P<0.01 orP<0.05),but not correlated with tumor～ross type(P> O.05).The expression of EphA2 was negatively related with E-cadherin.Conclusions The abnormal expression of EphA2 and E-cadherin may be together involved in the development and progression of eolorectal carcinoma,It may be a good marker for monitoring the malignant degree and the prognosis of colorectal carcinoma by combining E-eadherin and EphA2.

Objective To discuss the influence of parturition balloon on the labor course of primi-paras. Methods We divided 160 primiparas into the observation group and the control group with 80 cases in each group.We gave the observation group parturition balloon intervention with the help of midwife. Nursing measures in the control group were the same as those of the observation group except for the appli-cation of parturition balloon. We observed and compared the psychological status,pain;labor course,dehvery manner and postpartum hemorrhage between the two groups. Results The patients in the observation group got alleviation of psychological condition and pain.The rate of caesarean operation rate,postpartum hemorrhage and time cost of labor course were shortened,which were statistically different from those of the control group(P < 0.01 ). Conclusions Nursing intervention with parturition balloon for primiparas could alleviate pain of the patients, shorten time cost of labor course,improve rate of natural parturition and de-crease caesarean operation rate.It is a service model for delivery worthy of application.

Objective:To explore the influence of disease severity and effectiveness of antituberculosis treatment on helper T-cells in peripheral blood from patients with pulmonary tuberculosis.Methods:Th1 cells and Th2 cells of peripheral blood of 62 pulmonary TB patients and 30 controls were marked by intracellular cytokine(INF-? and IL-4 representative of Th1 and Th2 subsets respectively) and counted by Flow Cytometry.The levels of Th1 and Th2 cell count from patients with different disease severities radiologically before antituberculosis therapy were compared and their correlation with effectiveness of different antituberculosis treatment radiologically was analyzed either.Results:The baseline levels of Th1 cell count and Th2 cell count in pulmonary tuberculosis group before antituberculosis therapy were significantly lower than those in the control group(P0.05,t test).The levels of Th1 cell count in the stable group were still significantly lower than those in the control group(P

Gut microbiota(GM)consists of a complex community of microorganism species that live in the digestive tracts of animals including humans. Dysbiosis is believed to involve in the development of some diseases. Recently dysbiosis in the patients with Alzheimer′s disease(AD)and AD rat models was reported. GM may influence the pathogenesis and development of AD in several ways. Some neurotoxic substances produced by GM can invade into the brain via circulation and impair the neural functions. These sub?stances include ammonia,cyanobacteria-producedβ-N-methylamino-L-alanine,saxitoxin,anatoxin-αand amyloid. The decrease in brain-derived neurotrophic factor(BDNF)in hippocampus and cerebral cortex induced by dysbiosis contributes to the cognitive dys?function. Dysbiosis related endotoxin can induce inflammation,which is one important risk factor for obesity,insulin resistance(IR) and type 2 diabetes mellitus(TIDM). AD and diabetes have good correlation and similarity. Probiotics,prebiotics and Chinese herbal medicines can rebuild GM and have been reported to ameliorate the memory loss of AD patients or model rats. However ,whether and how their preventative and therapeutic effects on AD mediated by GM are worthy of further investigation.

BACKGROUNDTo investigate the efficacy and toxicity of ifosfamide, etoposide, and carboplatin (IEC) regimen in the treatment of patients with advanced non-small cell lung cancer.

METHODSThirty-three patients with advanced non-small cell lung cancer were treated with IEC regimen, which consisted of ifosfamide 2.0g/m²(patients with age > 70 years: 1.3g/m²), IV D1-3; etoposide 130mg/m², IV D1-3; carboplatin 300mg/m², IV D1, repeated every four weeks.

RESULTSOf the 33 patients, 7 cases got partial response, 24 had stable diseases, and 2 had progressive diseases, and the overall response rate was 21.2% (7/33,95% CI: 7.3% to 35.1%). The median survival and 1-year survival rate were 7.8 months (95% CI: 6.2 to 9.4 months) and 20.0%(95% CI: 6.0% to 34.0%) respectively. Main adverse effects were severe hematologic toxicities. The frequency of leukopenia,thrombocytopenia and anemia with grade III and grade IV was 51.5% (17/33), 18.2%(6/33) and 30.3%(10/33) respectively. There was significantly higher frequency of leukopenia (P=0.024) and thrombocytopenia (P=0.037) with grade III and grade IV in patients with age≥60 years than those with age < 60 years.

CONCLUSIONSIEC is an effective regimen in the treatment of patients with advanced non-small cell lung cancer. Main adverse effects are severe hematologic toxicities, which are more significant in elderly patients. It is necessary to apply G-CSF or GM-CSF protection to avoid severe myelosuppression for elderly patients.
