OBJECTIVE:To observe the clinical efficacy and complications of TCM in the adjuvant treatment of asthma and allergic rhinitis. METHODS:160 patients with asthma and allergic rhinitis were divided into control group and observation group according to the visiting order of odd or even,80 cases in each group. Control group received basic western medicine,such as lo-ratadine and budesonide used for allergic rhinitis,salmeterol/fluticasone and leukotriene for asthma;observation group additionally received TCM(inline treatment + external treatment),the treatment course was 3 months. Clinical efficacy and complications in 2 groups were compared. RESULTS:The observation group had 2 cases of fall-off patients,and the control group had 3 cases. The total effective rate in observation group was 97.43%,which was higher than control group(74.03%),the difference was statistical-ly significant (P<0.05). The incidence of complications in observation group was 8.97%,which was lower than control group (19.48%),the difference was statistically significant(P<0.05). CONCLUSIONS:TCM can obviously relieve clinical symptoms, improve efficacy and reduce the incidence of complications in the adjuvant treatment of patients with asthma and allergic rhinitis.

Objective To observe the clinical efficacy of plasma exchange(PE),PE combined with plasma bilirubin absorp-tion(PE+PBA),and PE combined with double plasma molecule absorption system(PE+DPMAS),to investigate the best treat-ment options for the patients of hepatitis B-associated subacute severe.Methods Totally 140 patients who had hepatitis B-associat-ed were randomly divided into a PE group,a PE+PBA group,and a PE+DPMAS group.The dinical symptoms and blood rontine, electrolytc and the main biochemical indexes were recorded both before and after treatment and compared among the three groups. Results The total effective rate was higher in the PE +DPMAS group than in the PE group and PE+PBA group,which were 70.8%,60.9%,67.4% respectively,but there was no significant difference(P >0.05).compared with before treatment,serum total bilirubin (TBIL),alanine aminotransferase (ALT),aspartic acid amino shift enzyme (AST),valley aminoacyl transfer peptidase (GGT),alkaline phosphatase (ALP),globulin (GLB)and other biochemical indexes decreased significantly after treatment in 3 groups (P <0.001).PA was increased in the PE group and decreased in the PE+PBA and PE+DPMAS group after treatment,the differences were significant(P <0.05).After treatment,PT was shortened in the PE group,the differences were significant(P <0.05),but there were no significant difference between the PE+PBA and PE+DPMAS groups(P >0.05).Serum K+ and Cl- was obviously declined after treatment in the PE group,there was significant difference(P <0.001).Serum Na+ was obviously declined after treatment between the PE + PBA and PE + DPMAS groups (P < 0.001 ),but the difference was no significant in the PE groups.Serum Ca2+ was significantly decreased in the three groups of patients after treatment(P <0.001).WBC,Hb and PLT were significantly statistical difference after treatment(P <0.05).Conclusion The three groups also can improve liver function and the treatment rate for the patients of subacute hepatitis B-associated severe hepatitis.PE+PBA and PE+DPMAS groups can effective-ly reduce two thirds of the overall usage of the plasma.PE+DPMAS groups that the quantity of Cl- ,Ca2+ ,Hb decline much least in the three groups show larger value in the clinical application.

Objective To investigate the clinical effect of IFNα combined with mannan peptide in treatment of patients with HBeAg-positive chronic hepatitis B ( CHB ). Methods Eighty HBeAg-positive CHB patients with HBV DNA quantity ranging from 10 to 10 eopies/mL were enrolled and randomized into the treatment group and the control group ( n = 40 for each ). Patients in treatment group were given daily subcutaneous injection of IFNα-2b 5,000,000 U for 52 weeks, and received mannan peptide 10 mg per intravenous injection or 2. 5 mg per intramuscular injection for a total of 2 to 3 treatment courses (12 weeks for each). The control group received only IFNα-2b treatment. Liver function, serum markers of hepatitis B, HBV DNA quantity and blood tests were performed before the treatment and at 2, 4, 8, 16, 26 and 52-week during the treatment; and the adverse effects were recorded. Results The rates for ALT normalization, negative HBsAg, negative HBeAg, HBeAg seroconversion and negative HBV DNA were 91. 8% , 17. 5% , 52. 5% , 27. 5 % and 47. 5% at 52nd week in the treatment group, while those in the control group were 80. 0% , 12. 5% , 30. 0% , 10. 0 % and 25. 0% , respectively. There were significant differences in HBeAg-negative, HBeAg-seroeonversion and HBV DNA-negative rates between two groups (χ2 = 4. 178, 4.021 and 4.381, P < 0. 05 ) , and these indexes in the treatment group were increased to 57. 5% , 30. 0% and 50. 0 respectively at 52nd week after drug withdraw. White blood cells began to be elevated at 4th week and were restored to the normal levels at 8th week in the treatment group, while the count in the control was lower than the normal value even at 52nd week of the treatment with the average of (3.45±1. 18)×109/L. Conclusion Alpha-interferon combined with mannan peptide therapy is effective for patients with HBeAg-positive CHB, which may restore the declined peripheral WBC counts induced by interferon and improve the compliance.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

OBJECTIVETo evaluate the influence of extreme ambient temperature on mortality and years of life lost (YLL) in Chongqing.

METHODSThe daily mortality, meteorology and air pollution index data in Chongqing from the 1(st) January 2010 to the 31(st) December 2013 were collected. Distributed lag non-linear model (DLNM) was used to assess the influence of daily ambient temperature on daily number of deaths and daily YLL respectively. The delayed and cumulative effects of extreme temperature on sex, age, and cause-specific mortality were also assessed.

RESULTSThe relationships between ambient temperature and non-accidental, cardiovascular disease and respiratory disease mortalities and YLL were U-shaped or W-shaped. The effect of heat was obvious on that day, peaked on day 7, and lasted for two weeks, whereas the effect of cold was obvious a week later and lasted for a month. As 1 ℃ increase of ambient temperature, the cumulative relative risks (CRR) of high temperature across lag 0-7 days on non-accidental, respiratory disease and cardiovascular disease mortalities were 1.05 (95%CI: 1.03-1.07), 1.08 (95%CI: 1.05-1.11) and 1.05 (95%CI: 1.01-1.09) respectively. The effects of heat on YLL for each cause were 23.81 (95%CI: 12.31-35.31), 14.34 (95%CI: 8.98-19.70) and 4.43 (95%CI: 1.64-7.21), respectively. On cold days, 1 ℃ decrease of ambient temperature was correlated with an increase in CRR of 1.06 (95%CI: 1.04-1.08), 1.09 (95%CI:1.06-1.12) and 1.06 (95%CI: 1.02-1.11) from lag 0 to 14 for non-accidental, respiratory disease and cardiovascular disease mortalities, respectively. The estimated YLL were 23.34 (95%CI: 10.04-36.64), 16.39 (95%CI: 10.19-22.59) and 2.61 (95%CI: -0.61-5.82). People aged ≥65 years tend to have higher CRR and YLL than those aged <65 years. On high temperature days, the CRR in women was higher than that in men, while the YLL in women was lower than that in men. On low temperature days, both the CRR and YLL in women were higher than those in men.

CONCLUSIONSBoth high and low ambient temperature have adverse health effects. People aged ≥65 years are more sensitive to both high and low ambient temperature. Younger men are more sensitive to high ambient temperature and women and elder men are sensitive to low ambient temperature. It is necessary to take targeted measures to protect the population in Chongqing from the adverse influence of extreme ambient temperature.

Glycosite-specific antibody‒drug conjugatess (gsADCs), harnessing Asn297 N-glycan of IgG Fc as the conjugation site for drug payloads, usually require multi-step glycoengineering with two or more enzymes, which limits the substrate diversification and complicates the preparation process. Herein, we report a series of novel disaccharide-based substrates, which reprogram the IgG glycoengineering to one-step synthesis of gsADCs, catalyzed by an endo-N-acetylglucosaminidase (ENGase) of Endo-S2. IgG glycoengineering via ENGases usually has two steps: deglycosylation by wild-type (WT) ENGases and transglycosylation by mutated ENGases. But in the current method, we have found that disaccharide LacNAc oxazoline can be efficiently assembled onto IgG by WT Endo-S2 without hydrolysis of the product, which enables the one-step glycoengineering directly from native antibodies. Further studies on substrate specificity revealed that this approach has excellent tolerance on various modification of 6-Gal motif of LacNAc. Within 1 h, one-step synthesis of gsADC was achieved using the LacNAc-toxin substrates including structures free of bioorthogonal groups. These gsADCs demonstrated good homogeneity, buffer stability, in vitro and in vivo anti-tumor activity. This work presents a novel strategy using LacNAc-based substrates to reprogram the multi-step IgG glycoengineering to a one-step manner for highly efficient synthesis of gsADCs.
