The systemic anaphylaxis murine model was induced by the injection of oval albumin (OVA)in aluminum hydroxide gel adjuvant. The death rate varied with the mouse species: 40-90% in Swiss and 69% in average,no death in C57BL/6 and 615 but some symptoms. developed. Swiss mice was adopted in this experiment.90% of mice pretreated with Lx remained living after allergen challenge,but only 20% in normal control. For elucidation the possible mechanism of Lx action,the study was carried out on detection of anti-OVA IgE specific antibody and histamin concentration in lung tissues. Passive cutaneous anaphylaxis(PCA)titers for anti-OVA IgE antibody in serum ranged from undilution to 160 in control group and not detectable in group pretreated with Lx. In addition, after absorption of PCA positive sera with anti-IgG antibody.the PCA activity was not affected. Histamin content was 1.54?0.24?g/ml in Lx treated mice caopared to 2.69?0.67?g/ml in control group(p

The main difficulties and disputable problems on develping the national standard Standardized Manipulation of Acupuncture and Moribustion, Part 3: Auricular Acupuncture are debated in this paper from the three aspects of its meaning, scientific basis and key point. The difficult points mainly include manipulation standandization of auricular acupuncture, basis and science of the standards stipulated, selection of technical terms and definition, and why only the four kinds of manipulations are used for auricular acupuncture. Finally, the authors suggest that the Standardized Manipulation of Acupuncture and Moxibustion, Part 3: Auricular Acupuncture needs further to be studied and improved.

Objective To learn the current status of job burnout and influencing factors for nurses from infectious disease hospital.Methods The Chinese version MBI -HSS was used to survey 218 nurses from infectious disease hospital,and linear regression was used to analyze the influencing facters of job burnout.Results A total of 210 questionairs were cocleted.The incidence of severe occupational job burnout was 22.38%,and the score of emotional exhaustion (EE), depersonalization (DP),personal accomplishment (PA)was(22.82 ±9.98),(6.48 ±5.20),and (35.20 ±8.82), respectively.Regression analysis demonstrated that the main influencing factors were entering the isolation ward, opportunity for infectious diseases ,disinfection damage,fear of occupational exposure and concern on family infection(P <0.05).Conclusion The status of job burnout of nurses in infectious disease hospital is not optimistic.There is a positive relationship with the working environment,occupational exposure.Managers need to explore an effective way to ease the job burnout of nurses,and to stabilize the nursing team.

This article mainly summarise the results of the chemical compositions and their pharmacological activities of Arnebiae Radix since 1966. The chemistry components isolated from Arnebiae Radix are mainly naphthoquinone, monoterpene phenol and quinone, phenolic acids and their salts, alkaloids, aliphatic and esters. Pharmacological results showed that the chemical compositions and the extracts of Arnebiae Radix have antibacterial, anti-inflammatory, anti-viral, hepatoprotection, antioxidant, anti-tumor and immune function and other activities. This article hopefully to provide a reference for further research, development and utilization of Arnebiae Radix.

Objective　To compare the Immunoreactivity of various HEV Antigen with Anti-HEV IgM. Methods Solid-phase enzyme immunoassay( EIA ) was developed for detecting anti-HEV IgM by using synthetic peptides E30, E42, E33, and recombinant antigen from HEV ORF-2. Results Of 60 anti-HEV positive sera by using E30, E42, E33 and recombinant antigen as coating antigen, Anti-HEV IgM positive rates were 76.7%, 26.6%, 18.3% and 66.7% respectively. In Acute-phase and convalescence-phase sera of the patients with Hepatitis E, Anti-HEV IgM positive rate was 90% and 3.3% respectively. Conclusions The HEV E30-based EIA will be very useful in the early diagnosis of Hepatitis E.

The optimized cultural medium of fermentation for Candida sp.mutant strain YQ5 to produce S-adenosylmethionine was studied.The results of single factor experiment showed that the most favorable pH value,carbon source,nitrogen source organic nutrient is 6.0,8% sucrose,1.5% tryptone and 2% yeast extract,respectively.As to inorganic salts,MgSO4?7H2O,CaCl2,FeSO4?7H2O,CoCl2,CuSO4?5H2O,H3BO3 could improve accumulation of the intercellular SAM.The ingredients of the culture medium are also opti-mized by the orthogonal experiment.Fermentation for 48 h under the optimal condition resulted in AdoMet production at 1740.0 mg/L.

Objective To explore the application of B-mode intra- and post-operative ultrasound in patients with traumatic brain injuries. Methods B-mode intra- and post-operative ultrasound were performed 35 times in 24 patients, including 7 times of intra-operation in 7 patients and 28 times of post-operation in 17 patients. Results During operation epidural hematomas in 3 cases as well as intracranial hematomas in 2 cases, subdural hematomas in 1 case, diffused brain swelling in 1 case were found. After operation epidural hematomas were examined in 4 cases as well as subdural hematomas in 1 case, delayed intracranial hematomas in 6 cases, scattered contusion and laceration of the brain in 12 cases, acute obstructive hydrocephalus in 1 case, and subdural hydroma in 4 cases. Six cases underwent operations again because of delayed hematomas, contusion and laceration of the brain. B-mode ultrasound was compared with CT scan and the total coincidence rate was 85.4%.Conclusions B-mode ultrasound is helpful to examine delayed hematomas and other emergent complications. It may save time and may improve rescue rate and has a good coincidence with CT scan. B-mode ultrasound may be widely used as a routine way in neurotrauma ICU.

Objective To explore the effect and compare the relapse rates of 1-desamino-8-D-Arginine Vasopressin(DDAVP) different withdrawal ways after initial 3 months in primary monosymptomatic nocturnal enuresis(PMNE) patients,in order to provide some evidences and references to use DDAVP to cure PMNE preferably.Methods Two hundred and fifty-six cases PMNE patients who were treated in Hubei Maternal and Child Health Hospital from November 2014 to June 2016 were selected and randomly divided into group A (DDAVP immediate withdrawal group,65 cases),group B(DDAVP day reduction group,58 cases) and group C (DDAVP step reduction group,60 cases).All patients were given DDAVP tables for 3 months.After 3 months for DDAVP,patients who were effective (full respond and partial respond) to DDAVP continued to undergo a withdrawal stage,those in group A underwent immediate cessation,those in group B continued to receive the effective dose every other day for 2 months and those in group C were step by step tapered by 0.05-0.10 mg every 2-4 weeks until completely stopped,the period was not more than 3 months.All patients had a follow-up visit for 3 months after cessation of DDAVP.Results A total of 183 patients completed the study finally,there were 65 patients in group A,58 patients in group B and 60 patients in group C.Initial 3 months the effective rates of group A,B and C were respectively 89.23％ (58/65),89.66％ (52/58) and 86.67％ (52/60),there were not statistically significant difference(x2 =0.309,P =0.857).There were 58 patients in group A,52 patients in group B and 52 patients in group C continued to undergo the withdrawal stage.One month after cessation of DDAVP,the effective rates of group B (88.46％,46/52) and group C (92.31％,48/52) were significantly higher than group A(67.24％,39/58) (x2 =7.030,P=0.008;x2 =10.417,P=0.001),while the relapse rates of group B(19.23％,10/52) and group C(17.31％,9/52) were significantly less than group A(36.21％,21/58) (x2=3.904,P=0.048;x2=4.937,P =0.026).Three months after cessation of DDAVP,the effective rates of group C (78.85％,41/52) were significantly higher than group A (50.00％,29/58) and group B (57.69％,30/52) (x2 =9.859,P=0.002;x2 =5.371,P=0.020),and the relapse rates of group C(32.69％,17/52) were significantly less than group A (55.17％,32/58) and group B (51.92％,27/52) (x2 =5.609,P =0.018;x2 =3.939,P =0.047),while the effective rates and relapse rates were not statistically significant difference between group A and group B(x2 =0.652,P =0.419;x2 =0.116,P =0.733).Severe adverse events related to DDAVP were not observed in any patients.Conclusion Gradual withdrawal after initial 3 months of DDAVP may improve the effect and reduce the relapse rates,the short-term and long-term curative effects of step-by-step withdrawal treatment are both well,while long-term curative effects of every other day withdrawal treatment is not obviously well.
