This paper collected the traditional Chinese medicine (TCM) prescriptions of osteoporosis and osteoarthritis from CNKI to set up database and used TCM inheritance system to analyze the composing principles in prescriptions. We collected 103 and 106 prescriptions for osteoporosis and osteoarthritis respectively, then analyzed inherent principles between herbs in prescriptions by using the TCM inheritance system, and obtained the frequency of each herb, and drug combinations of two diseases' prescriptions. The result showed that the principles in TCM prescriptions of osteoporosis and osteoarthritis are similarities, buch as tonifying kidney and invigorating the circulation of blood, but differences of the specific drugs. That is to say, tonifying kidney is the main method of osteoporosis treatment, however, invigorating the circulation of blood is the main method of osteoarthritis treatment.

Objective To investigate the mechanism of repression of testosterone biosynthesis in rats exposed to dibutyl phthalate (DBP). Methods Immature male rats were randomly divided into 5 groups involving 4 experimental groups and one control group. Animals were administered orally either corn oil only (vehicle control) or DBP (0.25, 0.50, 1.00, 2.00 g/kg) for 30 days. After 30 days exposure, the half of animals were sacrificed with testis, epididymis and adrenal selected and weighed. The ratio of organ to body weight were calculated and histopathological examination were examined. Testosterone (T), luteinizing hormone (LH), 17?-estradiol (17?-E2) and corticosterone (CORT) were detected by radioimmunoassay. After 15 days, the rest of animals were sacrificed and above-mentioned indexes were measured. Results The ratio of testis and epididymis to body weight reduced significantly at doses of 0.50 g/kg DBP and above. The testicle atrophy was observed, germinal epithelium became thin and the amount of reproductive cells obviously decreased. All of those were not repaired in convalescence stage. In above 1.00 g/kg DBP groups, the level of T, LH and 17?-E2 decreased (P

Recombinant plasmids pHY-PA, pBBR-PA were constructed in which genes pdc and adhB were placed under the control of tac promoter, respectively, and had successfully expressed in Escherichia coli. Then these recombinant plasmids were electroporated into Lactobacillus strains for ethanol production. Preliminary ethanol fermentation using these Lactobacillus strains and their recombinants was carried out using 42℃ as fermentation temperature. The results indicated that introducing pdc and adhB, ethanologenic pathway was successfully constructed in L.plantanum CICIM B0080. 0.4% (V/V) ethanol was detected at the end of fermentation with 6.7% glucose, and that is 67-fold as the wild-type B0080. Two-fold of ethanol production was detected in L.amylovorus B0112 (pHY-PA) and L.acidophilus B0068 (pBBR-PA). Introducing both pdc and adhB, and meanwhile knock-outing the lactate dehydrogrnase gene may better convert carbon flux to ethanologenic direction.

Objective To establish the preparation techniques for preparing the reference substance of platycodin-D.Methods Raw material of platycodi radix was extracted with 70 %MeOH.The concentrated extract passed through D101 macroporous resin column,then the 40 %alcohol eluate was separated by silica gel column chromatography with chloroform-methanol gradient elution.The fractions contained platycodin-D were collected and purified by HPLC.Results HPLC analysis and normalization of peak areas showed the purity of the platycodin-D was 98.8 %.Conclusions The preparation techniques are simple and high yield,can be used for preparing the reference substance of platycodin-D.

Objective To explore the relationship between TLR3 mRNA expression on peripheral blood mononuclear cells(PBMCs)and acute rotavirus(RV)diarrhea.Methods Sixty-one children with acute RV diarrhea served as study subject,the expression of TLR3 mRNA on PBMCs was detected by real-time fluorescence quantitative RT-PCR.the concentrations of IFN-γand TNF-α in serum were measured by the method of Enzyrme-linked immunosorbent assay(EUSA).Results The expression of TLR3 on PBMCs and the serum levels of IFN-γ and TNF-α in the serious diarrhea group were 0. 820±0.051,(33.67±12.88)Pg/ml, (62.21±14.65)pg/ml,respectively,while it were 0.717±0.040,(24.01±10.06)pg/ml,(50.99± 12.18)pg/ml in the slight diarrhea group,and 0.525±0.029,(12.52±5.19)pg/ml,(28.65±7.44)pg/ml in the control group.Compared with the control group.the expression of TLR3 on PBMCs and the serum levels of IFN-γ,TNF-α in the serious and slight diarrhea group were significantly higher(P<0.01).There were significant differences between the serious and slight diarrhea group(P<0.01).There were positive relationship between the expression of TLR3 on PBMCs and tHe serum IFN-γ,TNF-α levels(r=0.431,P< 0.05,r=0.372,P<0.05).Conclusion The expression of TLR3 on PBMCs in children with acute rotavirus dialThea iS up-regulated,TLR3 and its mediated immune response are associated with the development of acute rotavirus diarrhea.

ObjectiveTo explore the effect and mechanism of Toll-like receptor 4(TLR4) ligand LPS-mediated inhibition hepatitis B virus (HBV) replication in Bewo cells.MethodsFirst of all,2 μg 1.3-fold HBV recombinant vector pcDNA3.1 ( + )-HBV1.3 were transfected into Bewo cells,after 12 h,the cells were treated with LPS for 3 d.To observe the kinetics of IFN-β and TNF-α expression in Bewo cells,the Bewo cells were exposed to TLR4 ligand LPS.And the effect of pyrrolidine dithiocarbamate ( PDTC),an inhibitor of NF-κB,on LPS-induced cytokines was also observed.The HBsAg,HBeAg and HBV DNA level in the culture supernatant were detected by Microparticle Enzyme Immunoassay (MEIA) and fluorescence quantitative PCR,respectively,and the expression of IFN-β,TNF-α,TRIF and MyD88 was detected by ELISA and RT-PCR,respectively.ResultsCompared with control group,LPS could significantly suppress HBV replication in Bewo cells ( P ＜0.01 ),and it could induce the production of TNFα in Bewo cells ( P ＜ 0.05 ),in time-and dose-dependent manners.PDTC strongly inhibited LPS and induced TNF-α production,but had no much effect on IFN-β in Bewo cells ( P ＜ 0.001 ).Compared with control group,the mRNA levels of MyD88 were significantly induced by LPS in the Bewo cells transfected with this recombinant vector( P ＜ 0.001 ).ConclusionsTLR4 ligand LPS could significantly suppress HBV replication by inducing TNF-α production in Bewo cells mainly via the MyD88/ NF-κB signal pathway.

Objective To explore the value of temporary cardiac pacemaker therapy on children with Adam-Stoke syndrome(ASS).Methods Nine children with ASS was implanted the emporary cardiac pacemaker under X-ray or blinding inserted beside bed.Results Seven children was successfully implanted the temporary cardiac pacemaker within 1-2 d of ASS attack,and two children was successfully implanted at 10 d and 20 d after ASS attack, respectively. Five patients was cured, two children was died, and two children was implanted the permanent cardiac pacemaker. During pacing, two patients had the electrode shifted,and one patient had the cardiac murmur,and one patient had the local skin infected.Conclusion Temporary cardiac pacemaker can successfully treat children with ASS attack;the earlier the implantation,the better the prognosis.

Objective To study the value of application of histamine provocation test and airway resistance measurement in diagnosis and therapeutic efficacy in preschool children with asthma.Methods Histamine provocation test and airway resistance measurement by the Italian MEFAR MB3 provocating instrument and Germen Microloop lung function instrument for 42 cases who were diagnosed as asthmatic(27 patients with bronchial asthma and 15 cases of cough variant asthma)and 21 healthy cases was compared,and the differences between the 2 groups and the value of therapeutic efficacy were analyzed.Results The resistance ratio of respiratory tract of control group was(97.11?9.09)%,which in asthma and cough variant asthma group was(229.37?57.48)% and(248.80?76.80)%.There was significant difference between the 3 groups(F=48.466 P
