Objective To explore the anti-infection mechanism of carboxyamidotriazole (CAI) through studying the effects of CAI on the proliferation, apoptosis and degranulation of RBL-2H3 mass cells.Methods Compound 48/80 (C48/80) was used to induce the model of activation and degranulation in RBL-2H3 cells.The morphological change of cell degranulation was observed by neutral red staining.The release levels of histamine and β-hexosaminidase were measured by ELISA method and chromogenic assay, respectively.The cell activity was determined by CCK-8 method.And cell apoptosis was detected by Hoechst 33342 fluorescent staining.Results Compared with the control group, 10, 20, 40 μmol/L CAI inhibited C48/80-induced degranulation of RBL-2H3 cells in different degrees.CAI (20, 40 μmol/L) reduced the histamine release (P<0.01), and CAI (40 μmol/L) decreased the β-hexosaminidase release (P<0.01).In addition, the viability and apoptosis of RBL-2H3 cells were not affected at the concentrations of CAI used.Conclusions CAI can effectively inhibit the activation and degranulation of RBL-2H3 mast cells, and this effect is not through cytotoxicity.The anti-infection effect of CAI may partially due to the down-regulation of mast cell activity.

Objecitve To conclude the clinical manifestation of Fournier's gangrene (FG) and its emergency treatment.Methods From 2006 to 201 1,12 patient were involved in the study,all had received debridement,wide spectrum antibiotics and support therapy,the clinical manifestation,treatment choice and prognosis were analyzed retrospectively.Results All patients were male with 67.7 year-old mean age.Initial lesions were all in scrotal skin,an average procedures of each patient was 3.5,mean hospitalization days was 29.7 days.Surgical wound was healed by left scrotal skin in all cases,2 cases with huge urethra defect were received perineostomy.Ten cases were survived with 57-months follow-up and mortality was 16.7％.Conclusions Fournier is one of emergency disease of Urology.Its mortality is still high.Intensive care and appropriate anti-biotic therapy combined with surgical treatment is the key of FG's management.

Objective To explore the different operation modes for treating native renal pelvic and ureteral neoplasms occurring at the same side of transplanted kidney.Method A retrospective analysis was performed on 48 cases of native renal pelvic and ureteral neoplasms occurring at the same side of transplanted kidney,including 14 cases receiving open surgery (open surgery),22 cases receiving laparoscopic radical nephroureterectomy with bladder cuff resection through a lower abdomen oblique incision (oblique incision group) and 12 cases receiving modified endoscope assisted Plunk technique (Plunk group).The operating time,amount of bleeding and blood transfusion during operation,recovery of intestinal function,time of indwelling drainage tube and wound suture,the total cost of hospitalization,the hospital stay and the incidence of complications were comparatively analyzed.Result The operating time in open group was shortest.Group of Pluck is better than other groups in the aspects of Time of wound suture and intestinal function time in shorter in Plunk group than the rest two group (P＜0.05),and amount of bleeding and incidence of complication in Plunk group were higher than oblique incision group (P＜0.05).The incidence of complications and amount of bleeding were decreased significantly as compared with the rest groups (P＜0.05).Conclusion The mode of the laparoscopic radical nephroureterectomy with bladder cuff resection through a lower abdomen oblique incision has the advantages of high security,minimal invasion and satisfactory treatment effect.It is especially suitable for treating native renal pelvic and ureteral neoplasms occurring at the same side of transplanted kidney.

Objective To analyze the mutations of FMS-like tyrosine kinase 3 internal tandem duplication (FLT3/ITD) in bone marrow cells of patients with newly-diagnosed acute myeloid leukemia (AML).Methods The mutations of FLT3/ITD in 96 AML cases were detected by polymerase chain reaction (PCR)and the clinical features of FLT3/ITD positive patients were analyzed.Results FLT3/ITD mutations were identified in 18 patients (18.8 ％),2 cases were M2,11 cases were M3,2 cases were M4,3 cases were Ms.Patients with FLT3/ITD mutations presented higher initial white blood cell count than that of patients without FLT3/ITD mutations [18.0×109/L (3.6×109-137.6×109/L) vs 6.3×109/L (4.5×109-113.0×109/L),t =3.04,P ＜ 0.05].Out of FLT3/ITD positive patients,13/16 (81.3 ％) obtained complete remission and 13 patients remained in first remission in a median follow-up of 10 months(6-15 months).Conclusion The mutations of FLT3/ITD are frequently identified in newly-diagnosed AML patients,patients with FLT3/ITD mutations present high white blood cell count.

Objective: To observe the influence of electroacupuncture with different frequencies on rats swimming endurance and sift out the optimal frequency parameter.Methods: Wistar rats were randomly allocated to control group, non-acupoint group and electroacupuncture with low frequency group (EA with 2 Hz group), electroacupuncture with medium frequency group (EA with 15 Hz group), and electroacupuncture with high frequency group (EA with 100 Hz group), acupoints Zusanli (ST 36) and Taichong (LR 3) were punctured and rats load swimming time was used as an index, and the change of swimming endurance time before and after acupuncture was observed. Results: After electro-acupuncture, swimming time was increased in 15 Hz and 100 Hz groups respectively, with the significant differences between before and after acupuncture (P＜0.05). There was also a significant difference in the percentage of increase in swimming time between 15 Hz group and other groups (P＜0.05).Conclusion: It is suggested that electroacupuncture at acupoints Zusanli (ST 36) and Taichong (LR 3) with a frequency of 15 Hz could enhance rats's swimming endurance, and 15 Hz might be an optimal frequency parameter during the electrical stimulation.

Objective To study on the changes of the DNT cells and T lymphocyte subtype in children with infectious mononucleosis (IM) and its clinical significance.Methods The flow cytometry (FCM) was used to detected the DNT cells and other T lymphocyte subtype in 48 cases of IM.Results The study showed that DNT cells( 9.39 ± 4.89 )% were greatly increased in comparison with normal controls (NC) (4.26 ± 1.68)% ( P ＜0.01 ).CD4 cells(21.45 ±9.87)% were decreased ( P ＜0.01 ) and CD8 cells increased in comparison with NC (32.43 ± 5.07) % ( P ＜ 0.01 ).Conclusion DNT cells and T lymphocyte subtype can be used to evaluate the immune function of children with infectious mononucleosis (IM) and provide guidance for adoptive immunotherapy.

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.
