Gene expressions of interleukin-6 receptor subunit gp130 and gp80 were investigated by competitive RT-PCR in the rat model of osteoporosis. A significant increase in expressions of gp130 and gp80 was found in bone marrow of osteoporotic rat, this change may be a possible mechanism in osteoporosis due to loss of estrogen.

Objective To investigate the effect of total flavonoids of Herba Epimedii (HEF) on the apoptosis of osteoblasts in the ovariectomized (OVX) rats. Methods Fifty-four female rats were allocated into 6 groups (9 rats in each group) ; OVX group, sham-operated group, 3 groups with OVX followed by three different dosages of HEF(40,80 and 160 mg· kg-1·d-1) and another group by nilestriol (0.1 mg· kg-1·d-1) for 12 weeks respectively. Bone mineral density (BMD) of whole body of rats was determined by DEXA. The serum level of estradiol was measured by radioimmunologic assay. Apoptotic ceils were examined using terminal dexynudeotidyl transferase-mediated dUTP nick end labeling (TUNEL) and observed by electron microscope. The protein expressions of transforming growth factor (TGF)-β1 ,fibroblast growth factor (FGF)-2 and Fas were tested withimmunohistochemical methods. Results Compared with the OVX group,BMD in the HEF treated (80 and 160 mg ·kg-1·d-1) groups were increased (P < 0.01), but the serum level of estradiol was not increased (P >0.05). Positive expression rate of apoptotie osteoblasts and osteocytes in the OVX group was significantly higher than that in sham-operated group after 12 weeks (P < 0. 01), and were decreased after HEF treatment (P < 0.01).Compared with the OVX group, Fas expression in the HEF treated groups was significantly decreased (P < 0.01), and expressions of TGF-β1 and FGF-2 were significantly increased, especially in 80 and 160 mg·kg-1·d-1 HEF groups (P < 0.01). Conclusion HEF has antiosteoporotic effect in ovariectomized rats. HEF can inhibit apoptosis of osteoblasts and osteocytes, which may thus contribute to its antiosteoporotic effect.

Objective To investigate the effects of icariin on the expressions of osteoprotegerin(OPG)and receptor activator of nuclear factor-kB ligand(RANKL)mRNA in rat osteoblasts cultured in vitro.Methods Calvarial osteoblasts were obtained from newborn SD rats aged＜24 h by trypsin-collagenase digestion method. After treatment with different concentrations of icariin(10~(-10)-10~(-4) mol/L)for 48 h,total RNA was isolated from osteoblasts.Expressions of OPG and RANKL mRNA were detected by semiquantitative RT-PCR.Results Icariin remarkably increased OPG mRNA levels and decreased RANKL mRNA levels in calvarial osteoblasts in a dose- dependent fasion with a maximum effect at a concentration of 10~(-7)mol/L(P＜0.05).Osteoblasts pre-treated with icariin prevented the inhibitory effect of dexamethasone on OPG mRNA(0.570?0.093 vs 1.083?0.081)and the stimulative effect on RANKL mRNA(1.079?0.050 vs 0.718?0.082)(both P＜0.05).Conclusion Icariin upregulates OPG expression and downregulates RANKL expression in osteoblasts,which may explain the beneficial role of icariin in preventing and treating osteoporosis.

Objective To explore the efficacy and safety of sequential telbivudine ( LDT) therapy following interferon-α( IFN-α) in hepatitis B e antigen (HBeAg) positive chronic hepatitis B patients.Methods 94 chronic hepatitis B patients in our hospital hepatitis clinic archives from August 2008 to September 2013 were divided into two groups, 45 patients treated with LDT following IFN-αdue to unsatisfactory response to peginterferon-α-2a (peg-IFN-α-2a)treatment in the sequential group and 49 patients treated with LDT initially in the controlled group.In the sequential group, 22 patients failed to respond to IFN-αtreatment, 4 patients obtained IFN-resistance, 6 patients developed severe side effects, 1 patients had pre-C mutation and 12 patients switched to LDT due to economic factors or fertility requirement.The biochemical response and virological response, virological breakthrough and serological response were observed.Chi-square test was adapted for data analysis.Results After 32.35 months of LDT therapy, 88.9%(40/45) patients had with HBV-DNA <100 IU/mL in the experiment group compared with 44.9%(22/49) patients in the control group (P<0.05).The rates of HBeAg loss and HBeAg seroconversion in the experiment group were 53.3%(24/45) and 51.1%(23/45) respectively, which were significantly higher than that of the control group, 24.5%(12/49) and 24.5% (12/49) (P<0.05).6.7% (3/45) patients developed virological breakthrough in the sequential group compared with 34.7%(17/49) in the control group (P<0.05).Above results suggested the synergistic antiviral activity between peg-IFN-α-2a and LDT.Conclusion Sequential LDT therapy following peg-IFN-α-2a is better efficacy and safety compared with treating patients with LDT alone initially.

OBJECTIVE To investigate the variation of in vitro activity,the ?-lactamases,type diversity and the homology of multiple resistances in Acinetobacter isolated.METHODS The multiple resistant Acinetobacter were selected to detect susceptibility test by K-B antimicrobial agents.The resistant rates were analyzed by WHONET 5.4,the isolates ?-lactamases phenotype was detected by three-dimensional test,genomic types were measured by PFGE.The ?-lactamases genotype was determined by PCR assay with specific-primer,and DNA sequencing was also used to analyze resistance-related gene.RESULTS Twenty-eight of 45 strains were OXA producing strains(68.3%),10 strains were IMP producing strains(24.4%),13 strains were TEM producing strains(31.7%),18 strains were CTX-M producing strains(43.9%),6 strains were PER producing strains(14.6%),and 7 strains were AmpC producing strains(17.1%).None produced SHV ?-lactamases.Twenty-four strains were produced 2 or more than 2 kinds of ?-lactamases.CONCLUSIONS The multiple resistance of Acinetobacter can produce kinds of ?-lactamases,but producing ?-lactamases are not the only one mechanism.

This paper was aimed to investigate the effects of icariin on the expression of p38 mitogen activated protein kinase(MAPK)protein in rat osteoblasts cultured in vitro, to elucidate the signal transduction of icariin in preventing and treating osteoporosis. The results showed that p38MAPK could be activated by icariin within 5min, and Cbfal could also be upregulated, and SB203580, an inhibitor of p38MAPK pathway, could partly inhibit Cbfal upregulation by icariin.

Objective To investigate the protective and therapeutic effect of large doses of vitamin C on the acute lung injury in the model of rabbits induced by oleic acid. Methods A total of 18 rabbits were divided into four group randomly: control group(CG); oleic acid group(OG); preventive group(PG) and treatment group(TG). Oxygen pressure in arterial blood (PaO_(2)), superoxide dismutase (SOD) and malondialdehyde(MDA) in blood were measured in 0, 30, 90 and 150min, respectively. All the animals were killed in 150min later. Total protein in broncho-alveolar lavage fluid (BALF) and wet dry weight ratio of the right lung were measured, and the left lung sample was treated by formaldehyde for pathological test. Results PaO_(2), SOD in PG group and TG group were significantly higher than that in OG group(P

Objective: To assess the effect of taurine supplementation on behavior of young rats exposed to low-level lead. Methods: Wistar dam rats were randomly divided into three lead+Tau(0.5%, 1.0% ,1.5%)groups, lead group and control group.Dams of three lead+Tau groups were fed with food containing 0.5%,1.0%,1.5% taurine respectively from d 9 of gestation. Lead+Tau groups and lead group dams were given water containing 0.14% PbAc 2 ad lib. from d 16 of gestation to weaning of the off spring on d 25 post partum. The pups continued taking same food and water. The neurobehavioral function of pups was tested. Results: (1) Taurine supplementation could significantly decrease accumulation of lead in the brain of young rats. (2)Taurine supplementation was able to prevent Pb-induced retardation on behavioral development, and also learning and memory damage in young rats.(3) In all selected six brain regions, the content of NA and DA was decreased in lead group compared with control group. The content of NA in all six brain regions and DA in pituitarium, cerebellum and cortex in 1.0% taurine supplementation group could be restored to normal. The content of ACh in hippocampus and cortex was decreased in Lead compared to Cont group, and which could be corrected by Tau supplementation. Conclusion: The results suggest that taurine has protective function against Pb-induced toxicity and can protect the nervous system against Pb-induced damage in the development of young rats.
