OBJECTIVE:To investigate the hemostatic effect and safety of hemocoagulase in radical gastrectomy.METHODS:60 cases with gastric cancer were divided on average into 2 groups.Therapy group received hemocoagulase 2 KU during and after operation,and control group received dicynone 0.5 g and aminomethylbenzoic acid 0.2 g during and after operation.Intraoperative blood loss and amount of blood drainage at 6 h and 24 h after operation were observed.The value of D-dimer was monitored after operation.RESULTS:Intraoperative blood loss and amount of blood drainage at 6 h and 24 h after operation in therapy group were less than in control group (P

Objective To explore the nursing strategies for preoperative ventilator-dependent patients undergoing discontinuing mechanical ventilation after lung transplantation.Methods The clinical data and nursing experiences of 10 preoperative ventilator-dependent patients undergoing discontinuing mechanical ventilation after lung transplantation from September 2002 to December 2008 were retrospectively analyzed.Results The time of discontinuing mechanical ventilation ranged from 7 to 30 days and the average time was 16.5 days.Conclusion The key points to ensure the success of discontinuing mechanical ventilation were careful observation of ventilation modes,preparations before discontinuing,airway management,nutritional support and psychological nursing.

Objective To observe the changes of synaptosome membrane fluidity and intrasynaptosome free calcium in ovariectomized rats' brain and the therapeutical effects of genistein. Methods Thirty-six 3 month-old female Sprague-Dawley rats were randomly assigned to 4 groups:sham-operated,ovariectomized control,genistein and estradiol benzoate groups.Normal saline(50??l),normal saline(50??l),genistein(250??g)and estradiol benzoate (50??g)were subcutaneously injected respectively once every other day for 8 weeks,and then synaptosome membrane fluidity and intrasynaptosome free calcium in frontal and parietal lobe and hippocampus were detected. Results The intrasynaptosome free calcium of cerebral cortex and hippocampus synaptosomes of ovariectomized control group (?s)are (243.31?31.21)nmol/L and (305.10?54.31)nmol/L respectively.There are significantly statistical differences as compared ovariectomized control group with sham-operated,genistein and estradiol benzoate groups(P0.05).The synaptosome membrane viscosity(?)of hippocampal synaptosomes of ovariectomized control group(?s)is 3.03?0.39,which has significantly statistical differences compared with sham-operated and estradiol benzoate groups(P0.05).Conclusion The synaptosome membrane fluidity decreased while intrasynaptosome free calcium increased in ovariectomized rats' synaptosomes.Genistein can enhance the membrane fluidity and maintain intrasynaptosome free calcium in ovariectomized rats' synaptosomes.

Objective To study the effect of myocardial ischemic preconditioning on activity of ATPase and creatine kinase(CK) in high blood fat rat. Methods High blood fat rat mode was established from SD rats.The rats were randomly divided into three groups: ischemic preconditioning(IPC), ischemic/reperfusion(I/R) and control group.The activity of CK in coronary outflow,the activity of malonyldialdehyde(MDA),superoxide dismutase(SOD),glutathione perodxidase(GSH-Px) and ATPase in myocardium were dectected. Results CK and MDA were significantly less in IPC group than those in I/R group.In IPC group,the activity of SOD,GSH-Px,Na~(+)-K~(+)-ATPase,Ca~(2+)-ATPase and Ca~(2+)-Mg~(2+)-ATPase were much higher than those in I/R group. Conclusion Myocardial ischemic preconditioning can protect high blood fat rat from ischemic/reperfusion injury.

Objective To assess the efficacy and safety of tolterodine on late-onset overactive bladder symptoms after prostate brachytherapy due to prostate carcinoma.Methods Twenty-six prostate cancer patients diagnosed by biopsy,who underwent prostate brachytherapy using iodine-125,were recrui(t)ed in this trial.All cascs complained of overactive bladder symptoms 6 months postoperatively.The 26 patients were divided into 2 groups:14 men in tolterodine group (TR group) who were given tolterodine 2 mg twice a day; 12 men in tamsulosin group (TS group) who were given tamsulosin 0.2 mg once a day.Efficacy was assessed by changes in IPSS,OABSS and nighttime voiding at 2 weeks and 4 weeks after medical treatment respectively.Safety was assessed by postvoid residual (PVR) and acute urinary retention (AUR),dry mouth,constipation and tachycardia at the fourth week after medical treatment.Results The age,tumor staging,GS,PSA,initial prostate volume,IPSS,OABSS,nighttime voiding,iodine-125 seeds implanted and needles punctured of both groups were comparable.IPSS,OABSS and nighttime voiding were significantly improved in TR group after 2 weeks of medical treatment and the above parameters were significantly improved than TS group (14.4 vs 18.3,5.9 vs8.4,1.4 vs2.5).OAB symptoms of TR group were also significantly improved than TS group after 4 weeks of therapy.There were no significant differences of PVR and AUR,dry mouth,constipation and tachycardia between both groups.Conclusions Tolterodine is effective and safe in treating late-onset OAB symptoms after prostate brachytherapy,although the occurence of dry mouth and tachycardia might be increased.

Objective To study the influence of different dialysis frequence on infection and prognosis of maintenance hemedialysis patients. Methods Fifty-three maintenance hemodialysis patients with chronic kidney disease were divided into 3 groups. Groups A, B, C dialysed thrice per week (19 cases),twice per week (15 cases) and thrice per two weeks (19 cases), respectively. All the patients were dialysed for 1 year. The rate of infection, death number and death reason were recorded. Results All the cases were infected 62 times (17 times in group A, 18 times in group B and 27 times in group C). Pulmonary infection,blood vessels infection, urinary tract infection and digestive tract infection happened 35 times(56.45% ), 14 times (22.58%), 8 times (12.90%) and 5 times (8.06%) respectively. Eight cases died in three groups,and the total death rate was 15.09%, with 1 case in group A,1 case in group B and 6 cases in group C.There was significant difference in prognosis among three groups (χ2 =6.293,P <0.05). Conclusions Patients who dialysis less than twice per week have higher rate of infection and death. Dialysis program should be adjusted and dialysis frequence should be increased.

Objective To comprehend the status of Helicobacter pylori (Hp) infection in type 2 diabetes mellitus (T2DM) patients, and study the relationship between Hp and T2DM. Methods Seven hundred and sixty-eight in-hospital T2DM patients (T2DM group, including new diagnosed 194 patients and re-diagnosed 574 patients) and 172 sex, age matched health individuals(control group ) were involved in this study. 14C-urea breath test (14C-UBT) was proceeded in both groups to determine Hp infection, and infection rates were calculated. Results Total Hp infection rate in T2DM group was significantly higher than that in control group [56.0%(430/768) vs 37.8%(65/172) ,P< 0.01], delamination analysis according to sex also showed significant differences between T2DM group and control group(P < 0.01). The rate of Hp infection in new diagnosed patients and re-diagnosed patients, female patients and male patients had no significant difference (P > 0.05 ). The rate of Hp infection in different age and sex had no significant difference (P >0.05 ). Conclusions The rate of Hp infection in T2DM patients is higher than that in non-T2DM patients.Hp infection has relationship with T2DM, and has no relationship with age, sex and course of disease.

Objective: To detect estrogen receptor α and β(ER-α, ER-β)protein expression in different age of mouse thymus.Methods:Protein expression of ER-α and ER-β in thymus was analyzed via immunohistochemistry.Moreover,the relationship between ER-α and cytokeratin 18(epithelial cell marker)was further tested through fluorescence double-staining.Results: Immunohistochemical analysis revealed that both ER-α and β protein was found in nuclei of some thymocytes of 3 month mice.However,expression of ER-β was absence while ER-α was still positive in aged mice, such as 12 months and 16 months old.Double staining further confirmed that lots of ER-α/β positive cells were Foxp3 negative cells.Conclusion: Expression of ER-β is absent while ER-α is still positive in thymus of aged mice, which indicates ER-α is the critical estrogen receptor that involves in thymic involution.Moreover, ER-α/β do not participate in Treg development within thymus.
