BACKGROUND: As the first long-acting atypical antipsychotics, the therapeutic effect and safety of risperidone microsphere have been proved. However, it may lead to serious pain due to the deep intramuscular injection.OBJECTIVE: To evaluate the pain levels by 12-week injection of rispeddone microsphere and to explore the relationship among dose and times of injection of risperidone microsphere and pain levels.METHODS: A total of 57 patients diagnosed as schizoprenia by DSM-Ⅳ, aged 18-65 years, were selected and injected risperidone microsphere once every 2 weeks with doses of 25, 37.5 and 50 mg. The pain levels were evaluated using 100 mm visual analogue scale during injection and at the injected sites. The effects of injected dose, injected frequency and injected sites on the pain were analyzed by the nurse questionnaire.RESULTS AND CONCLUSION: The pain levels among the different doses groups had no notable differences (F=1.35,P> 0.05), which demonstrated that the pain had no relationship with injected dose. However, the pain level of injected sites had correlation to injected doses. The pain level of the 50 mg group was greater than that of the 37.5 and 25 mg groups. Accordingly,patients who treated by high dose of risperidone microsphere should be intervened by nurses.

Objective To compare treatment and efficacy of thoracolumbar fractures by using three different screw fixations:traditional approach,the vertebral side clearance into the road and percutaneous pedicle. Methods A total of 82 single segmental thoracic lumbar fractures cases hospitalized from March 2011 to March 2014 ,with male 67 cases ,female 15 cases ,and average age(33.7+/-12.5)years old. Patients were randomly divided into three groups:traditional approach group (n = 23),operation through paraspinal muscle gap group (n = 30),percutaneous group(n = 29). These following indicators will be compared in three groups:duration of operation ,intraoperative blood loss ,intraoperative fluoroscopy time ,postoperative flow ,VAS scores before and after operation and Oswestry disability index , difference of spinal sagittal position Cobb′s Angle. Results Compared with the traditional approach group ,operation through paraspinal muscle gap group and percu-taneous group have obvious advantages in duration of operation,intraoperative blood loss,postoperative flow,VAS scores before and after operation ,the Oswestry disability index. Additionally ,above mentioned three surgical methods could recover kyphosis deformity ,and there was no statistically significant difference among three groups (P > 0.05). Conclusion In the treatment of monosegmental thoracolumbar fractures ,compared with traditional approach ,operation through paraspinal muscle gap and percutaneous pedicle screw internal fixation have more advantages which includes fewer trauma,less bleeding,faster recovery and lower incidence of postoperative low back pain.

Objective:To investigate the effect of EPO on humoral and cellular immunity and the monocyte antigen presenting function in patients with chronic renal failure(CRF).Methods:60 patients with CRF were divided into three groups.Group A patients accepted hemodialysis and treated with EPO.Group B patients treated with EPO and didn't accept hemodialysis.Group C patients didn't accept EPO treatment and hemodialysis.After 8 weeks treatment,the subpopulations of T lymphocyte were analyzed with detected by flow cytometry analysis method;Immunoglobulins were measured with radioactive immuntzation method.In addition,the infection rate of patients with CRF in every group was compared.Results:The parameters of immune functions of patients with CRF were comparable between groups before treatment.After treated with EPO for 8 weeks,RBC numbers and Hb were significantly increased in patients of group A and group B,but not in patients of group C.IgG and IgA were increased in patients of groups A and groups B and have statistic differences as compared with that in patients of group C(P

Objective To assess the safety and efficacy of patients with acute myelogenous leukemia treated with mitoxantrone/arabinosylcytosin versus daunorubicin/arabinosylcytosin.Methods We searched Pubmed,Embase,the Cochrane Library,Chinese biomedicine literature database,Chinese Scientific Journals full-text database,and Chinese Journal full-text database for randomized controlled trials comparing MA regimen with DA regimen.We manually searched key Chinese magazines of related fields.The quality of included studies was evaluated and graded according to Cochrane Reviewer's Handbook.Results Nine randomized controlled trials totaling 608 patients were included.Meta-analysis results were as follows:There was significant difference between MA regimen and DA regimen in total complete remission rate [RR=1.24,95%CI(1.10,1.40)]and effective rate[RR =1.22,95%CI(1.09,1.36)] after the second course of treatment.There was significant difference between MA regimen and DA regimen in heart toxicity incidence [RR=0.54,95%CI(0.29,0.99)],infection incidence [RR=1.56,95%CI(1.29,1.94)],agranulocytosis time [RR=2.70,95%CI(2.09,3.31)].There was no significant difference in nausea and vomitting [RR=0.96,95%CI(0.87,1.07)].Conclusion Current clinical studies might confirm that MA regimen is superior to DA regimen in complete remission rate and effective rate in treating the patient with initial treatment acute myelogenous leukemia.Fewer patients receiving MA regimen experienced heart toxicity incidence compared with patients receiving DA regimen,but more experienced infection and agranulocytosis.They still need to be confirmed by large sample,high quality randomized controlled trials.

Regional saturation technique has been applied in MR scaning widely. It is possible to obtain MRA or MRV by putting the REST slab on one side of slice or another. REST eliminates artifacts caused by motion or blood flow and minimizers wrap artifacts along the phase encoding and high quality of images can be provided.

Objective To investigate influence of hyperlipidemia in parents on plasma lipid level,blood pressure,body mass index(BMI) and waist circumference(WC)of their children.Methods Eighty children whose parents had been with hyperlipidemia(Group A) and 893 children whose parents had been normal plasma lipid levels(Group B) were studied.BMI,systolic pressure(SP),diastolic pressure(DP),WC,plasma triglyceride(TG),cholesterol(CH),high density lipoprotein-cholesterol(HDL-c),low density lipoprotein-cholesterol(LDL-c)of two groups were measured and compared.Results The levels of BMI,TG,TCH,LDL-c,SP,and DP had a increasing trend in group A compared to those of group B.HDL-c in group A had a decreasing trend compared to that of group B.But only the increase of BMI is significant(P

20 was lower than those whose BMI≤20(P

Objective To study the inhibitory effects of GANT61, as an inhibitor of Gli, on the growth of human esophageal adenocarcinoma cell lines OE19 and OE33, and their mechanisms thereof. Methods After treating with different concentrations of GANT61(30,20,13.333 3,8.888 8,5.925 9,3.950 6,2.633 7,1.755 8,1.170 5μmol/L),the cell viabilities of OE19 and OE33 were detected by MTS method, which expressed by IC50. The Gli1and Gli2 mRNA expressions treated with GANT61(10 μmol/L GANT61) or DMSO for 24 h were detected in OE19 and OE33 cell lines by real time fluorescence quantitative PCR. The protein expressions of Gli1, Gli2 and CyclinD1 treated with GANT61 or DMSO for 24 h were detected in OE19 and OE33 cell lines by Western blot assay. Transwell invasion assay was performed to evaluate the inhibiting effect on OE19 and OE33 cell invasion by the treatment of GANT61 or DMSO. Results The IC50 of GANT61 was 8.08μmol/L in OE19 and 9.65μmol/L in OE33 cells. Compared with DMSO group, Gli1 and Gli2 mRNA expressions and Gli1,Gli2 and CyclinD1 protein expressions were significantly decreased in OE19 and OE33 cells of GANT61 group (P<0.05). The number of penetrating cells was significantly reduced in OE19 and OE33 cells of GANT61 group compared with that of DMSO group (P<0.01). Conclusion GANT61 can inhibit the growth and invasion of esophageal neoplasms cells by down-regulating Gli1 and Gli2 mRNA expression,which indicates that Hedgehog signaling pathway may play an important role in carcinogenesis and progression of esophageal adenocarcinoma.

The understanding of nocturia has been much changed in last decade. Recently, nocturia has been recognized as a separate clinical entity within the lower urinary tract symptom complex. The pathophysiology of nocturia is multifactorial and can be complex and its cause remains unclear in a significant number of patients. Although the successful introduction of DDAVP to decrease nocturnal urine output in severe nocturia resistant to conventional treatment demonstrated new perspectives in management of nocturia, the primary treatment modality must be based on the disease. We reviewed the definition and etiologies of nocturia, offering the current diagnostic procedures and standards of care and we suggest practical tip for the management of nocturia.
