This study was performed to prepare immobilized β-glucosidase and snailase, then optimize and compare the process conditions for conversion of icariin. Immobilized β-glucosidase and snailase were prepared using crosslink-embedding method. The best conditions of the preparation process were optimized by single factor analysis and the properties of immobilized β-glucosidase and snailase were investigated. The reaction conditions including temperature, pH, substrate ratio, substrate concentration, reaction time and reusing times of the conversion of icariin using immobilized β-glucosidase or snailase were optimized. Immobilized β-glucosidase and snailase exhibited better heat stabilities and could remain about 60% activity after storage at 4 degrees C for 4 weeks. The optimized conditions for the conversion of icariin were as follows, the temperature of 50 degrees C, pH of 5.0, enzyme and substrate ratio of 1 : 1, substrate concentration of 0.1 mg x mL(-1), reaction time of 6 h for β-glucosidase and 2 h for snailase, respectively. In 5 experiments, the average conversion ratio of immobilized β-glucosidase and snailase was 70.76% and 74.97%. The results suggest an effect of promoted stabilities, prolonged lifetimes in both β-glucosidase and snailase after immobilization. The immobilized β-glucosidase and snailase exhibited a higher conversion rate and reusability compared to the free β-glucosidase and snailase. Moreover, the conversion rate of immobilized snailase was higher than that of immobilized β-glucosidase. The process of icariin conversion using immobilized β-glucosidase and snailase was moderate and feasible, which suggests that immobilized enzymes may hold a promise for industrial usage.

OBJECTIVETo observe the effect of Shen warming Pi strengthening method on expressions of serum T cell subsets (C045+%, C03+%, and C04 +/COB+) in diarrhea-predominant irritable bowel syndrome (IBS-0) rats. Methods An IBS-0 rat model was established referring to AL-Chaer's modeling method combined with tail clamp and intragastric administration of sanna leaf. After modeling 30 SO rats were randomly divided into 6 groups according to random digit table, i.e., the model group, the high, middle, low dose Wenshen Jianpi Recipe (WJR) groups, and the Sishen Pill control group, 6 in each group. A normal control group consisting of 6 SO rats were also set up. Rats in high, middle, low dose WJ R groups were administered by gastrogavage with boil-free WJ R at the daily dose of 3. 100, 1. 550, 0. 775 g/kg, respectively. Rats in the Sis hen Pill control group were administered by gastrogavage with boil-free Sis hen Pill at the daily dose of 0. 736 g/kg. Equal volume of normal saline was given by gastrogavage to rats in the model group and the normal control group. All medication lasted for 2 successive weeks. Rats' general state, expressions of T cell subsets (CD45+%, CD3+%, and CD4+ /CDB+) changes were observed.

RESULTSCompared with the normal control group, expressions of CD45+% and CD3+% increased, but CD4+ /CDB+ decreased with statistical difference (P < 0. 05). Compared with the model group, expressions of CD45+% and CD3+% decreased, but CD4+ ICDB+ increased with statistical difference in high, middle, low dose WJR groups, and the Sis hen Pill control group (P <0. 05). Compared with the Sis hen Pill control group, there was statistical difference in all indices except CD45+ value in the low dose SWPSM group (P <0. 05). Compared with the low dose WJ R group, the expression of CD3+% decreased in high and middle dose WJR groups, and the Sis hen Pill control group; CD4+ /CD8+ increased in the Sishen Pill control group and the high dose SWPSM group (all P < 0. 05).

CONCLUSIONSWJR showed better treatment effect. The mechanism of Shen warming Pi strengthening method might be achieved by regulating expressions of CD45+% and CD3+%, and CD4+ /CD8+ ratios.

Objective To investigate the understanding level of asthma related knowledge and the treatment compliance in parents of children with asthma in Tianjin. Methods Questionnaire survey was given to 93 randomly selected parents of children with asthma at our asthmatic clinic ,whose children began to receive regularly asthmatic administration for at least 6 months from June to July in 2009. Results 72.04% of the parents included into the survey knew that asthma was a chronic airway inflammatory disease; 100% of them adhered to use prescription inhaled corticosteroid (55.91%) or inhaled corticosteroid combined with an inhaled long-acting β2-agonist (44. 09% ) ;74. 68% of them believed that if the child is in a well control state, he/she could participate in exercise as healthy children. There were 93.55% and 97.85% children patients aged ＞ 5 had never used PEF meter or CACT respectively to monitor the ill conditions. 25.81% of the parents chose rapid-acting β2-agonist to deal with asthma at acute attack stage, while 19.35% chose to add antibiotics and 11.83% were unable to do anything. 43.01% of the parents worried that the long-term use of inhaled corticosteroid would have side effects on the growth and development of their children, although they chose to obey to the doctor's prescription. Conclusions The general understanding of asthma is good in the parents, whose children had received asthmatic administration regularly in Tianjin area,but there are still some weak links exist. The related education may help asthmatic children's parents to master the knowledge of asthma, give them correct recognition of the treatment and prevention of asthma,increase the treatment compliance. This work should be insisted continuously.

Protamine (PRM) is one of the most abundant arginine-rich nucleoproteins in sperm and plays an important role in spermatogenesis. In the late stage of spermatogenesis, the replacement of PRM by histone prompts the closer combination between the nuclear matrix of sperm and nucleoprotein in order for high enrichment and condensation of nuclear chromatin in addition to preventing the sperm genome from mutation induced by internal and external factors. With the development of DNA sequencing techniques, researches on the association between PRM polymorphisms and male fertility are surfacing as a hot field. Many studies show that rs2301365 polymorphism is a risk factor for male infertility and increases the risk of male infertility by 27 - 66%, that rs737008 polymorphism of PRM1 and rs1646022 polymorphism of PRM2 are protective factors against Asian infertility, and that the ratio of PRM1 to PRM2 is intensively associated with male infertility. This review presents an update on the association between PRM gene polymorphisms and male infertility.
