Objective To observe the therapeutic effects and toxicities of bone marrow-sparing intensity-modulated radiation therapy (BMS-IMRT) for postoperative cervical cancer.Methods From January 2011 to June 2012,totally 70 postoperative patients with cervical cancer were divided into BMS-IMRT group with 34 cases and IMRT group with 36 cases randomly.External whole pelvic intensitymodulated irradiation combined with chemotherapy was carried out for all patients.The planning target volume received a dose of 45 Gy/25 fractions in all patients.Delineation of the pelvis and limitation dose were carried out in BMS-IMRT group:the pelvis V30 ≤ 50％.All cases received chemotherapy with cisplatin (40 mg/m2) once a week concurrently with radiotherapy.Results Treatment was completed in 67 patients,as the other 3 patients stopped chemotherapy because of myelosuppression.There was no statistically significant differences between two groups for the 2-year local control survival(LCS)and overall survival(OS),alimentary tract toxicity and urinary toxicity.IMRT group had more serious hematologic toxicity than BMS-IMRT group,with statistically significant difference (x2 =14.355,P ＜ 0.05).Conclusions The postoperative cervical cancer patients with poor prognostic factors who undergo concurrent chemoradiotherapy,IMRT group has more serious hematologic toxicity than BMS-IMRT group.The short-term effect and other toxicities reaction are similar between two groups.

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.

Objective To evaluate the efficacy and safety of COOK cervical dilatation balloon for induced labor in full -term pregnancy . Methods There were 98 cases of cervical ripening and induced labor by using COOK balloon from January 2014 to April 2015 ( experimental group ) and 130 cases of cervical ripening and induced labor by using oxytocin from January 2010 to September 2013 ( control group ) .The cervical scores , childbirth way , and adverse reactions were compared between the two groups . Results After the removal of the balloon, the cervical scores in the experimental group increased from (2.38 ±0.70) points to (6.15 ±0.96) points (t=31.412, P =0.000).The rate of vaginal delivery in the experimental group (79.6%, 78/98) was significantly higher than that in the control group [62.3%(81/130),χ2 =7.910, P=0.005].The incidence of chorioamnionitis in the control group was 5.4% (7/130), which was significantly lower than that in the experimental group [18.4% (18/98), χ2 =9.647,P=0.002).The other adverse reactions in two groups had no statistical difference (P >0.05). Conclusions Use of COOK cervical dilation balloon is a safe and effective method to promote cervical ripening .In combination with artificial rupturing membrane or intravenous infusion of oxytocin can improve the success rate of full -term pregnancy induced labor .

The preparation method, serum stability, efficiency of cellular uptake and apoptosis induction of the cell penetrating peptide TAT and cleavable PEG co-modified liposomes loaded with paclitaxel (C-TAT-Lipo) were investigated. The best preparation procedure was performed by orthogonal test based on single factor screening method. First, the paclitaxel (PTX)-loaded liposomes were prepared by filming-rehydration method, evaluated with entrapment efficiency and polydispersity index. The morphology of C-TAT-Lipo was characterized by transmission electron microscopy. Turbidity variations were monitored in the presence of fetal bovine serum (FBS) to evaluate the serum stability of the liposomes developed here. Next, the efficiency of cellular uptake of different Rho-PE-labeled liposomes on B16F1 cells in vitro was evaluated by confocal laser scanning microscopy (CLSM) and flow cytometry. The quantitative analysis of apoptosis induced by different PTX-loaded liposomes was performed by Annexin V-FITC/PI double staining. The optimal formulation was as follows: Chol : lipid: 1 : 8 (molar ratio); drug : lipid: 1 : 40 (mass ratio); lipid concentration: 3 mmol x L(-1); temperature of hydration: 25 degrees C. The mean size and polydispersity index of C-TAT-Lipo were about (97.97 +/- 3.68) nm and 0.196 +/- 0.037, the zeta potential was (-0.89 +/- 0.45) mV, the entrapment efficiency of paclitaxel was (90.16 +/- 1.53)%. The particle sizes did not exhibit significant variations in 50% FBS over 24 h at 37 degrees C. The efficiency of cellular uptake of the C-TAT-Lipo increased 1.40 fold following the cleavage of PEG. Apoptosis analysis showed 59.3% increase of the apoptosis and necrosis profile of C-TAT-Lipo after the detachment of PEG shells, which was markedly higher than that of N-TAT-LP with or without glutathione and SL, respectively. The results indicate that the C-TAT-Lipo is successfully prepared by filming-rehydration method and shows significant antitumor activities.

Epilepsy is one of the most common diseases in children.The diagnosis,classification and treatment of epilepsy are improving gradually and meet with the international standards.However,the understanding of the clinical significance of epilepsy combined with the mental and behavioral problems is not sufficient,which leads to the backlogging of the diagnosis and intervention of the co-morbidity,and further affects the long-term prognosis.The prevalence of epilepsy co-morbid with attention deficit hyperactivity disorder (ADHD) is high,which seriously affects the quality of the lives in children and their families.Timely diagnosis and standardized treatment is very important for the clinical workers to improve the long-term prognosis of these children.In this paper,the possible mechanism,the disease characteristics,the standardized diagnosis and treatment of epilepsy combined with ADHD,are briefly introduced.

Methods Bottom clearance in Fuling section of Three Gorges Reservoir was carried out in Fuling district during the period from May to December in 2002. All the data related to clearance were collected before and after the bottom clearance. Based on the collected data, the effect of clearance was assessed. Results 5 882 general pollution sources, 68 contagion pollution sources were cleaned in Fuling district, the clearance rates of both were 100%. The rat densities in agriculture areas and the dismantling cities were 3.97% and 2.97% respectively before rat extinguishment, then became 0.65% and 0.33% after rat extinguishment. Conclusion Through the bottom clearance of Three Gorges Reservoir, contagion and general pollution sources in the emigrant areas have been cleaned up, so water pollution in Three Gorges Reservoir and the rats mediated diseases have been prevented and controlled.

Objective To evaluate the effect of catheterization on the serum prostate specific antigen (PSA) in acute urinary retention (AUR) patients due to benign prostate hyperplasia (BPH). Methods The data of 35 patients with AUR due to BPH were analyzed, and the changes in serum PSA values were compared before and after catheterization. The effect of AUR on serum PSA in BPH patients was discussed. Results It has been found that serum PSA declined from 9.93?8.85ng/ml to 6.46?5.75ng/ml after catheterization for the patients of AUR with BPH, and the values showed a significant difference (P0.05) in the patients in whom the serum PSA ≤4ng/ml, while a significant difference existed in both the group of patients in whom the serum PSA was 4~10ng/ml (from 5.95?1.43ng/ml to 4.09?2.00ng/ml, P10ng/ml (from 18.93?8.49ng/ml to 11.49?6.37ng/ml, P4ng/ml.

Objective To establish a model of homogenous bladder transplantation without blood vessel anastomosis in rat,and to investigate the outcome of the transplanted grafts.Methods 20 newborn SD rats were used as donors,and a total of 20 Wistar rats of 5-week-old were used as the reeipiemts for transplantation of homogenous bladder.The grafts were harvested from the SD rats,and they were wrapped with the greater omentum of the recipients without blood vessel anastomosis.Immunosuppressive agent was given postoperatively.10 rats were sacrificed on the 7th day and the remainings rats were sacrificed on the 14th day after bladder transplantation.The transplanted bladder grafts were observed grossly and microscupicully.Results Of 20 rats undergone homogenous bladder transplantation,19 rats were alive and the grafts were in good condition microscopically.There was no obvious rejection reaction in the transplanted bladders.The bladder mucosa,blood vessels and muscle layers of the grafts appeared to be normal microscopically.Conclusions The homogenous bladder transplantation into the omentum without blood vessel anastomosis in rats is considered to be a kind of stable animal model,with a higher survival rate of the tramsplanted bladder.
