Objective To explore the correlation of rhinovirus infection and the morbidity of asthma in children.Methods The RV gene in nasopharyngeal secretion of 30 children with asthma acute exacerbation(asthma group),30 children in asthma clinical remission(remission group) and 30 healthy children (control group) were detected by reverse transcription-polymerase chain reaction(RT-PCR).The total serum IgE(T-IgE) was determined by chemiluminescence.The eosinophil(EOS) count (EOS%) of peripheral blood and lung function were also measured.Results The rhinovirus infection rate was 36.67% in asthma group and 3.33% in remission group.No rhinovirus was detected in control group.The rate of rhinovirus infections in asthma group was significantly highter than that in remission group and control group(?2=7.50,13.47 Pa0.05). FEV1% was (62.73?13.54)% in asthma rhinovirus infection and (86.42?17.78)% masthma with no rhinovirus infection.There was remarkable difference between 2 groups(F=14.553 P﹤0.05). The T-IgE was (836.32?44.801) kU/L and EOS% was 10.63?4.09 in asthma group with rhinovirus infection.The total IgE was (439.10?231.28) kU/L and EOS% was 5.04?2.64 in asthma group with no rhinovirus infection.There was significant difference between 2 groups(U=2.475,F=20.806 Pa0.05).Conclusions There is a close correlation between rhinovirus infection and acute attack of asthma(or worsening asthma) in children. Asthma exacerbations would be likely to happened easier because of rhinovirus infection in asthmatic children with high T-IgE.

OBJECTIVETo reveal the relation between endogenous hormones and the flower bud differentiation in Schisandga chinensis.
METHODTop buds of extremely short branch and axillary buds of long branch in the same plant of S. chinensis were used as material and the contents of endogenous hormones were measured during different periods of the flower bud differentiation with HPLC.
RESULTThe result showed that flower bud differentiation and the formation of female flower were inhibited by high concentration of GA3 and were promoted by high concentration of ABA or ZT. Low ratio of GA3/ABA has the same result.
CONCLUSIONThere was a correlation between endogenous hormones and the flower bud differentiation of S. chinensis.

OBJECTIVETo explore the association of 8-hydroxyguanine glycosidase OGG1 Ser326Cys polymorphism with semen quality and the risk of male infertility.
METHODSThis case-control study included 620 idiopathic infertile patients and 385 normal fertile controls. We determined their genotypes by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and analyzed their semen quality by computer-aided semen analysis (CASA).
RESULTSThe individuals with OGG1 326 Cys/Cys showed significantly lower sperm motility and concentration ([52.1 +/- 26.7]% and (3.75 +/- 0.91) x 10(6)/ml, ln transformed value) than the Ser/Ser carriers ([59.0 +/- 21.8] % and (4.12 +/- 0.88) x 10(6)/ml, ln transformed value) (P < 0.05). The risk of male infertility increased 69% in the OGG1 326Cys allele carriers as compared with the Ser carriers (OR = 1.69, 95% CI: 1.24 -2.31).
CONCLUSIONOGG1 326 Ser/Cys polymorphism might contribute to the risk of male infertility in the southern Chinese population.

Objective To understand the status quo and demanding of resident pension service in Chongqing urban communities to provide the reference for constructing the community pension service system.Methods The questionnaire survey was conducted on 1 080 residents aged 50 years old or older in the nine districts of Chongqing City.Results 89.1% of the respondents didn't have any pension service,but the currently facing maximal difficulty Was the low proportion of medicare reimbursement,the main service that the elderly wanted to get was life care,security safeguards services and ordinary medical help;73.4% of the respondents were willing to try the integrated pension service model.Conclusion The government or related departments should optimize new pension resources,increase the funding sources,make reasonable overall planning and construct the pension service model.

Aim To study the mechanism of the anti-aging effect of total extract of astragalus(TEA) in mice. Methods MDA content, the activities of Mn-SOD and GSHpx and the reduced to oxidized glutathione (GSH/GSSG) ratio in mitochondria of D-galactose(D-gal) treated mice and 17-month-old mice were measured. Results Treatment with TEA(40 mg?kg-1?d-1 ig) for 10 wk would lower the content of MDA and restore activities of Mn-SOD,GSHpx and GSH/GSSG ratio in mitochondria of D-gal treated mice.Treatment with TEA (40 mg?kg-1 ?d-1 ig) for 3 mon had the same effect on 17-month-old mice.Conclusion TEA has anti-aging effect on D-gal treated mice and 17-month-old mice significantly, probably being related to its anti-oxidative effect.

OBJECTIVETo investigate the effects of Shenqi Fuzheng injection (SQFZI) combined with docetaxcl, flurouracil and calcium folinate in treating advanced gastric carcinoma, and to evaluate the action of SQFZI for enhancing therapeutic effect and alleviating adverse reaction of chemotherapy.
METHODSSixty advanced gastric cancer patients were assigned to two groups randomly, the control group treated with chemotherapy alone and the treated group treated with SQFZI combined chemotherapy. Chemotherapy regimens (TFC) was given to all patients consisting of docetaxel 75 mg/m2 intravenous dripping on the 1st day, flurouracil (5-FU) 350 mg/m2 and calcium folinate (CF) 120 mg/m2 intravenous dripping with micro-pump continuously from day 1 to 5, for 21-28 days as a cycle. To patients in the treated group, starting from 3 days before chemotherapy, SQFZI 250 mL was dripped every day for 14 successive days. The clinic effects were evaluated after two-cycle treatment.
RESULTSThe short-term effective rate was 40.0% in the treated group and 33.3% in the control group. As compared with those in the control group, patients in the treated group after treatment had a higher Karnofsky score (chi2 = 7.21, P < 0.05) and body weight (chi2 = 11.47, P < 0.05), lesser adverse reactions in decreasing of peripheral blood leucocyte, damage of peripheral nerve, adverse reaction of gastrointestinal tract, as well as better immune function.
CONCLUSIONSQFZI could effectively improve the clinical symptoms induced by chemotherapy regimen TFC, alleviate the adverse reaction, raise patients' quality of life and their immune function.

OBJECTIVETo investigate the pathogenic factors of human cytomegalovirus (HCMV) infections.
METHODSTotally 36 serum samples were obtained from early pregnant woman and examined with ELISA for anti-HCMV antibody IgG and IgM. After artificial abortion,chorionic villus and decidua were also examined with polymerase chain reaction (PCR) for HCMV-DNA. When the results of PCR were positive, pathological changes of these chorionic villus and decidua were analyzed.
RESULTSThe results showed that only 10 samples were PCR positive while IgG and/or IgM antibody to HCMV was positive. After infection with HCMV, different changes occurred in chorionic villus and decidual trophoblastic cells placental villus were hyperplasic and decidua cells degenerated and necrotized followed by lymphocytes infiltration.
CONCLUSIONThese pathological changes may be one of pathogenic factors of HCMV.
