Objective To evaluate the efficacy and safety of desloratadine citrate disodium versus epinastine for the treatment of chronic urticaria (CU).Methods A randomized,double-blind,double-dummy controlled clinical trial was conducted.Patients with CU were divided into test group and control group to be treated by oral desloratadine citrate disodium (8.8 mg/d) and epinastine (10 mg/d) respectively once a day for 28 days.All the patients were followed up after starting treatment.Therapeutic effect was evaluated,and adverse reactions were observed.Results One hundred and fifty-seven patients were enrolled in this study,and 142 patients were valid for evaluation of efficacy and safety at the end of study.After treatment for 28 days,there was no significant difference between the test group and control group in response rate (81.16 ％ vs.78.08 ％,P ＞ 0.05) or incidence rate of adverse reactions (13.89 ％ vs.12.16 ％,P＞ 0.05).Conclusion Desloratadine citrate disodium is effective and safe for the treatment of CU.

Objective To investigate the effects of treatment of syphilis in pregnancy on perinatal prognosis. Methods Patients of syphilis in pregnancy from Hainan Provincial People′s Hospital and Haikou Municipal Maternal and Child Health Center during 1995.1 to 2001.1 were collected for retrospective analysis. Pregnant women with syphilis were divided into treated group and untreated group according to whether they received penicillin anti syphilis treatment or not during pregnancy. Results The total number of deliveries in the 2 hospitals during that period was 18 701, and 61 out of 9 805 women screened for syphilis were positive, giving an incidence of 6 2/1000. The perinatal mortality rates were 11 2% in treated group and 83 3% in untreated group, and incidences of congenital syphilis were 17 6% and 72 7% respectively. Conclusion Syphilis in pregnancy is a serious complication to harm the fetus. Screening of syphilis during pregnancy is necessary, and penicillin treatment is effective which may reduce the perinatal mortality rate and the birth of congenital syphilis baby.

[Objective]To study the best time for infusing antibiotics as prophylaxis against infection in hip arthroplasty.[Method]Ninty cases of hip arthroplasty were divided into 6 groups randomly with 15 cases each.Ampicillin(UNASYN,1.5g) and cefuroxime axetil(Zinacef, 2.0g) was administered by intravenous infusion respectively one day or one hour before operation or 30 minutes after the operation began.Blood samples from peripheral vein,cancellous bone of acetabulum when reaming,medullary canal of femur when rasping and catheter right after the operation were harvested.Serum Bactericidal Activities(SBAs) were determined by minim dilution technique and were compared between the groups.[Result]SBAs of UNASYN and Zinacef are similar to the bacteria most commonly causing infection after prosthesis implantation such as staphylococcus.Percentage at SBA≥1:8 of UNASYN and Zinacef is significantly more at the beginning of operation and when reaming acetabulum than the other groups(P

Then it argues on the basis of analyses from such perspectives as methodology, disciplinary system development and macro policy environment that only through appropriate training in hospital management can the current status of the management personnel in domestic hospitals be changed, the professional advancement of the management personnel in the third-tier hospitals be genuinely realized, and the support and impetus for maintaining the competitiveness of domestic third-tier hospitals in the medical market be provided.

Objective To observe the dynamic changes of interferon gamma(IFN-?) and transforming growth factor bata1(TGF-?_1) in animal model of hyperoxia-induced lung injury,and to explore the mechanism of fibrosis.Methods Thirty-two juvenile Wistar rats were randomly divided into room-air group and hyperoxia group,the hyperoxia group were further divided into 3 subgroups of hyperoxia-exposure for 3,7 and 14 days.The mRNA levels of IFN-? and TGF-?_1 in the lung were measured by reverse-transcription polymerase chain reaction(RT-PCR).The expressions of IFN-? and TGF-?_1 protein were measured by immunohistochemical(stai)-ning.Results The level of IFN-? mRNA of groups under hyperxia-exposure for 3,7 and 14 days were higher than that of control group.The expression of IFN-? mRNA notably elevated and was up to its peak(P

Objective: To investigate the effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

Objective To evaluate the effects of dexmedetomidine on the activity of nuclear factor kappa B (NF-κB) in neutrophil granulocytes during one-lung ventilation in the patients undergoing pulmonary lobectomy.Methods Thirty-eight ASA physical status Ⅰ or Ⅱ patients,aged 40-64 yr,weighing 50-75 kg,scheduled for elective pulmonary lobectomy,were randomized into 2 groups (n =19 each) using a random number table:control group (group C) and dexmedetomidine group (group D).In group D,dexmedetomidine 1.0 μg/kg was infused intravenously over 15 min before induction of anesthesia,followed by infusion at a rate of 0.5 μg· kg-1 · h-1 until 30 min before the end of operation.The equal volume of normal saline was given in group C.At 5 min after intubation,0,30 and 60 min of one-lung ventilation,0 and 30 min of two-lung ventilation,and 30 min after operation,blood samples were taken from the radial artery for blood gas analysis and for measurement of plasma concentrations of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).The oxygenation index and respiratory index were calculated.The nuclear protein of neutrophil granulocytes was extracted for measurement of NF-κB DNA-binding activity.Results Compared with group C,the respiratory index,plasma concentrations of TNF-α and IL-6 and NF-κB DNA-binding activity were significantly decreased,and no significant difference was found in the oxygenation index in group D.Conclusion Dexmedetomidine can inhibit the activation of NF-κB in neutrophil granulocytes and is helpful in reducing the systemic inflammatory responses during one-lung ventilation in the patients undergoing pulmonary lobectomy.

Objective To explore the effect of pre-hospital nursing intervention in the new regional cooperative rescue model on treatment delay and the therapeutic effect in patients with myocardial infarction.Methods From January 2012 to May 2014,158 patients with acute myocardial infraction (AMI) were selected.Patients were divided into two groups,intervention group and control group,The first medical contact to balloon(FMC-to-B) time,referral time,cardiac function were analysed.Results Mean FMC-to-B time [(94±21)min vs.(102±23) min],referral time in nursing intervention [(5±3) min vs.(9±4) min)] were significantly shorter than those in control group (t=2.14,6.67,P＜0.05).After a month compared with control group,LVEF was increased [(54.8±6.9)％ vs.(48.8±6.9)％],and LVED was deceased [(50.1±8.2) mm vs.(50.5±5.6)mm] in intervention group.Conclusions Pre-hospital nursing intervention can decrease the FMC-to-B time,which could improve the cardiac function.
