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.

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 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 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 control the quality of Shujin Jiegu tablets by determining the content of dracorhodin in the preparation by HPLC.Method With dracorhodin as index,the content of dracorhodin in the preparation was determined by HPLC.Results Dracorhodin showed a good linear relationship in the range of 1.53～7.66 ?g,r =0.999 9.The average recovery was 98.64%,RSD=1.12%.Conclusion This method is simple,rapid,repeatable,and applicable to the quality control of the preparation.

Objectives To evaluate mini/VITAL and BacT/Alert, two fully automated blood culture systems. Methods Standard mini/VITAL AER and ANA bottles (bioM′erieux, Marcy 1′Etoile, France) and BacT/Alert FAN aerobic and FAN anerobic bottles (organon Netherlands) were used. The bottles were analysed over a period of 7 days. A total of 600 samples of blood, 108 samples of body fluid, and 100 strains of imitation were detected by mini/VITAL and BacT/Alert parallelly. The bottles of flagged positive were smeared and Gram stained before being examined under a microscope. Subcultures were performed in parallel on fresh blood agar and chocolate agar incubated in microaerophilic Conditions with 5% CO 2. All the bottles flagged negative were examined in the same conditions as the positive bottles. Results mini/VITAL: The positive rate for aerobic and anaerobic blood cultures was 10% and 5% respectively, for aerobic body fluid culture was 26 9%. No contaminants were detected. 0.5% false positive and 0.8% false negative were detected. 90% of positive sample were detected in 48 h. The shortest time of report of positive bottles was 1.5 h for blood culture. BacT/Alert: The rate of positive of aerobic and anaerobic blood culture was 9.8% and 5% respectively. The positive rate of body fluid culturs was 26.9%. There were used 3 bottles contaminated. The false positive and false negative rate were 0.5% and 0 98% respective. 95.5% of positive bottles were detected in 48 h. The shortest time of flagged positive was 2.5 h. Conclusion mini/VITAL and BacT/Alert were accurate automated blood culture systems for the detection of bacteremia. There was no significant difference on the speed of detection between BacT/Alert FAN bottles and mini/VITAL standard bottles.

Objective To establish a novel method for rapid identification and drug resistance of Moraxella catarrhalis, Different sourses of blood and the formula of chocklate agars were detected the Growth Index(GI). Methods Moraxella catarrhalis from specimens contaminated by microbial flora were isolated with a choclate agar with 50 mg/L vancomycin (CHOC-V) method. Nine media were inoculated,on which GI were calculated and compared. beta-Lactamase were determined by nitrocefin slip method. Results 228 strains of Moraxella catarrhalis and 203 strains of recent limbus bacteria were examined. The sensitivity of this method was 100%,and the specificity was 100%. The GI of Moraxella catarrhalis on chocklate agars and blood agars was higher than that of the BCA, NUA, MHA ( P

Objective To explore the efficiency of establishing regional critical neonate cure branch centers in decreasing the mortality of neonates and improving the neonatal emergency technology in the hospitals in primary level.Methods According to the admittance standards,critical neonate cure branch centers were founded in the qualified level II maternal and child health hospitals,meanwhile,a series of measures of quality supervision were adopted.We compared the situation of one year before the foundation of centers with that of after the foundation about the quality index of medical care,scientific research and teaching as well as economic indicator.Results During one year after the establishment of regional critical neonate cure branch centers,the annual amount of the inpatients and critical patients as well as the rescue achievement ratio increased,the annual mortality rate reduced,the rate of passing the new teaching test of asphyxia rescue increased and was above 90% in all centers except one,the incidence of neonatal asphyxia decreased in majority of the centers,both financial income and the capability of scientific research and teaching enhanced.Conclusion The establishment of regional critical neonate cure branch centers is beneficial to improve the provincial central hospital as well as the hospitals in primary level.It utilizes medical resource efficiently,promotes the maternal and child health hospitals in primary level to develop diagnosis and treatment as well as scientific research.The establishment is beneficial to raise the survival rate of the pathological neonate,degrade disability rate of the pathological neonate.The medical cost was expended appropriately,so it is worth to be spread generally according to Chinese situation.
