Objective To investigate the effect and safety of patients with diclofenac sodium lidocaine analgesia after endoscopic opera-tion. Methods One hundred patients with the implementation of nasal endoscopic treatment in our hospital from August 2012 to June 2014 were randomly divided into observation group and control group with 50 cases in each group. The observation group were injected the diclofe-nac sodium lidocaine,which compared with the control group given fentanyl through a vein for postoperative analgesia with analgesia effect and safety. Results The differences of HR,SBP,DBP,MAP indicators were not significant between and within groups (P>0. 05) with immedi-ately after operation, postoperative 24 h,48 h after surgery. There was no significant difference on the VAS score between the inmmediately after the operation process and compared to the control group (P>0. 05). The observation group with the immediate postoperative VAS score decreased significantly compared with that of the control group after 1 h,4 h,8 h,16 h,24 h,48 h of the surgery,while the observation group VAS scores were significantly lower than that of the control group (P<0. 05). The observation group in analgesia occurred in 6 cases of ad-verse reactions ( 12%) was significantly lower than that of 16 cases of the control group ( 32%) , and the difference was significant (P<0. 05). Conclusion Better effect and low incidence rate of adverse reaction is showed that diclofenac sodium lidocaine analgesia of patients with nasal endoscopic operation.

Objective To investigate the etiology and treatment of severe infection after ureteroscopic holmium laser lithotripsy. Methods Seven cases (2 men and 5 women) of severe infection after holmium laser lithotripsy under ureteroscope were treated.Their mean age was 44 years (range,37-56 years). The patients were characterized by a temperature over 39 ℃,a heart rate over 110 BPM,and a blood pressure below 80/50 mm Hg (1 mm Hg=0.133 kPa) within 1-12 hours after the operation.The diagnosis of septic shock caused by gram negative bacteria was suggested by the clinical manifestation and the urine culture. Anti-shock therapy was conducted with rapid supplement of colloidal and crystalloid solution of 3000-4000 ml.The vasoactive drugs,dopamine (2-5 ?g/kg per minute) or norepinephrine (4-8 ?g/kg per minute) were used for the establishment of stable circulation,and the third generation cephalosporins for the control of infection empirically.Low dose corticosteroids (dexamethasone,10-20 mg) were administered if the patients had adrenocortical insufficiency or significant intoxication. Results All patients were treated successfully within 8 to 48 hours,then the hypertensors were gradually stopped.Their temperature and blood routine tests returned to normal 3 days later.. Conclusions The causes of severe infection after holmium laser lithotripsy under ureteroscope are preoperative urinary tract infection,high perfusion pressure or postoperative urinary tract obstruction.Peri operative anti infection and appropriate operation skill can effectively prevent the infection.

Objective To explore the personality characters of patients with mental disorders and to determine the differences of dimension,trait level and model of personality between patients and normal subjects.Methods The patients with mental disorders(n=376) and normal subjects(n=368) were assessed with revised NEO personality inventory(NEO-PI-R).Results The mean scores of extroversion(E) and conscientiousness(C) of five-factor personality model of NEO-PI-R in patients were significant lower than those in normal group((P

Objective To breed homozygous mice of Treg-Th17 fluorescence double labeling and to investigate the role of Treg-Th17 balance in endotoxemia. Methods Mice of Treg and Th17 fluorescence single labeling were brought from Harvard Medical School,USA and were mated and bred based on the genetic rules.The genomic DNA was extracted from the tails of second generation weaning mice for genotyping by polymerase chain reaction (PCR).Thereafter,the homozygous mice of fluorescence double labeling were selected to have successive inbreeding for three generations and their genotypes and growth status were measured.The endotoxemia model in vivo was duplicated and changes of Treg-Th17 balance were detected by flow cytometry analysis at 24 h and 48 h after endotoxemia. Results Among the seven second generation mice in the first batch,only three (two males and one female) were the wanted homozygotes.Meanwhile,the genotypes of their offsprings for the next three generations were all Foxp3 RFPKI-homo IL-17A GFPKI with normal growing status.As important component of endotoxin,lipopolysaccharide (LPS)could induce significant signal expressions of red fluorescence protein (RFP) and green fluorescence protein (GFP).The ratio of CD8a + Foxp3 +,CD8a + IL-17A +,CD4 + Foxp3 + and CD4 + IL-17A + in the lymphocytes went up significantly in the group of 24 hours of LPS treatment,as compared with the control group (P ＜ 0.01 or P ＜ 0.05 ),while the difference between the control group and the group of 48hours of LPS treatment had no statistical significance (P ＞ 0.05). Conclusion Foxp3 RFPKI-homoIL-17A GFPKI mice have identical genotypes and stable genetic characteristics and is a model animal and novel research platform that can provide real-time monitoring of the changes of Treg-Th17 balance in vivo.The role of T reg-Th17 balance works significantly at 48 hous after the subject is exposed to LPS stimulation,and the roles of CD8a + Foxp3 and CD8a + IL-17A + in Treg-Th17 balance require further investigation.

Objective To explore the effect and mechanism of Kuntai Capsule (KC) on premature ovarian failure in rats.Methods Totally 40 SD female rats were randomly divided into four groups:control group,model group,Kuntai Capsule (KC) group and conjugated estrogens tablets (CET) group.The premature ovarian failure model in rats was made by ig administration of 75 mg/kg tripterygium.After the model was established,rats were continually treated with 0.6 and 0.625 g/kg of KC and CET respectively by ig administration for 36 d.HE staining was used to observe the morphology of ovary and count the number of follicle.The enzyme-linked immunosorbent assay (Elisa) method was used for the detection of follicle stimulating hormone (FSH),luteinizing hormone (LH),serum estradiol (E2),and anti-Mueller tube hormone (AMH) level.The real-time fluorescence quantitative PCR (qRT-PCR) method was used to detect the mRNA expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF).Results Compared with control group,the number of primordial follicles,preantral follicles and antral follicles were significantly reduced,the number of atretic follicles was increased (P ＜ 0.05),E2 and AMH significantly decreased (P ＜ 0.05),FSH and LH levels increased significantly (P ＜ 0.05),and the levels of VEGF and bFGF mRNA in model group were significantly decreased (P ＜ 0.05).Compared with model group,the number of primordial follicles,preantral follicles,and antral follicles were significantly increased,the number of atretic follicles was significantly reduced (P ＜ 0.05),E2 and AMH significantly increased (P ＜ 0.05),FSH and LH levels significantly decreased (P ＜ 0.05),and the levels of VEGF and bFGF mRNA in KC group were significantly increased (P ＜ 0.05).Conclusion By regulating the level of hormone and up-regulating the expression of VEGF and bFGF,KC can repair the damaged ovarian tissue and promote the growth and development of the follicle,so as to inhibit the premature exhaustion of mRNA.

AIMTo observe the differences of hemodynamics and nitric oxide synthase(NOS) activity of ventricular cardiac muscle in two septic shock models and explore the possible mechanism.

METHODSTwo rat models of septic shock[lipopolysaccharide(LPS)-induced and cecal ligation and puncture (CLP)-induced septic shock] were used. The hemodynamic parameters and nitric oxide synthase activity of ventricular cardiac muscle were measured.

RESULTSThe hemodynamic parameters in CLP-induced model were increased in the early stage and decreased in the late stage while in LPS-induced model the parameters showed the same change of the CLP late stage. Both LPS model and CLP model (late stage) showed significant increase in NOS activity, but there was no difference between the two models. After treatment of the NOS inhibitor N-nitro-L-arginine methyl ester (L-NAME), the parameters of CLP-late stage and LPS model increased significantly. The NOS activity reached the highest level in the CLP-middle stage. The production of nitrite/nitrate decreased significantly in LPS model and CLP model(late stage) after treatment of L-NAME, but the nitrite/nitrate produced by constitutive NOS in LPS model was higher than CLP model(late stage).

CONCLUSIONThe increase of the NOS activity may be the main reason to lead to the depression of the hemodynamic parameters. Inducible NOS may play the leading role in the LPS model while cNOS and iNOS have the same effect in the CLP model.

Glioma is one of the most common primary tumors in the human brain with poor prognosis. The local and systemic immunosuppressive environment created by glioma cells enables them to evade immunosurveillance. Myeloid-derived suppressor cells (MDSCs) are a critical component of the immunosuppression system. They are a heterogeneous cell population composed of early myeloid progenitor cells and precursor cells. Although the cells are diverse in phenotypes and functions, they all have strong immunosuppressive functions. MDSCs are extensively infiltrated into tumor tissues and play an important role in the glioma immunosuppressive microenvironment, which also hinders the immunotherapeutic effects of glioma. This article will review the phenotypic characteristics of MDSCs in the glioma microenvironment and their role in the progression of glioma. It is of positive significance to better understand the pathogenesis of glioma and explore effective comprehensive treatments.
