The therapeutic effects and mechanisms of traditional Chinese kidney-tonifying drugs in treating osteoporosis have become the focus under study. Pharmacological studies have shown that traditional Chinese kidney-tonifying drugs are promoters for the proliferation of osteoblasts, inhibitors for the activity of osteoclasts, regulators for the estrogen level and its receptor, plays important roles in promoting osteogenesis and suppressing adipogenesis of marrow mesenchymal stem cells (MSCs), modulating the function of OPG/RANK/RANKL system and the metabolism of calcium and phosphorus, as well as antioxidation. The anti-osteoporotic active ingredients and pharmacological action mechanism of traditional Chinese kidney-tonifying drugs are summarized from the perspective of molecular and cell biology in this paper, so as to provide references for the study of their mechanism of anti-osteoporosis and for the development of traditional Chinese kidney-tonifying and bone-strengthening drugs.

Objective To construct a recombinant human adenovirus type 3 ( HAd3 ) vector ex-pressing one major epitope of dengue virus type 1.Methods The gene encoding the envelope protein (304-314 aa) of dengue virus type 1 was inserted into the hypervariable region 1 ( HVR1 ) of HAd3 hexon by using overlap PCR.The recombinant gene was cloned into the shuttle plasmid, then linearized with AsisⅠrestriction enzyme and co-transformed into Escherichia coli BJ5183 strains with the digested backbone plas-mid for homologous recombination.The recombinant plasmid pBRAdΔE3GFP-DENV1 was transfected into AD293 cells to rescue recombinant adenovirus strains (rAdΔE3GFP-DENV1).ELISA and Western blot as-say were performed to evaluate the humoral responses induced in BALB/c mice after the immunization with rAdΔE3GFP-DENV1 strains.Results The recombinant adenovirus strains were successfully rescued. ELISA and Western blot assay showed that the antibodies in serum sample could recognize dengue virus type 1 strains.Conclusion The recombinant adenovirus strains expressing the epitope of dengue virus type 1 were successfully constructed.This study provided evidence for the development of multivalent vaccines against dengue virus.

OBJECTIVE To investigate the risk factors and treatment of nosocomial pulmonary fungal infection after open heart surgery.METHODS A total of 11040 consecutive patients who underwent open heart surgery were retrospectively studied from Jan 2004 to Dec 2006.And the clinical data of 324 patients with microbiologically documented nosocomial infection were analyzed.RESULTS There were 61 infected cases caused by fungi,accounted for 18.8% of all infections during the same period.Sixteen patients died.All infected patients had serious original heart diseases,and received previously glucocorticoids and broad-spectrum antibiotic therapy.The number of senile and pediatric patients was 28.Forty three patients developed postcardiotomy cardiorespiratory and renal function failures,and circulatory assist was established in 22 patients.Thirty six patients prolonged mechanical ventilation time for over one weeks.Thirty four patients developed hyperglycosemia.Candida albicans was the predominant pathogen(39 strains,63.9%),followed by C.glabrata(15 strains,24.6%).Results of susceptibility test showed that fluconazole,itraconazole and flucytosine presented highly antimicrobial activity.CONCLUSIONS Developments of nosocomial pulmonary fungal infection is closely associated with the severity of preoperative underlying heart diseases,prolonged mechanical ventilation and longer period of broad-spectrum antibiotic therapy.

Objetctive To summarize the associated complications with circulatory support device,and provide reference for chnical practice.Method A total of 8306 consecutive patients who underwent open heart surgery,in Department of Post-operation Intensive Care Unit of the Cardiac Surgery,Anzhen Hospital,Capital Medical University,was retrospectively studied from January 2005 to February 2007.And the clinical data of 246 patients including 63 female and 183 male patients with mean age 56.7±14.2 years supported with various circulatory support devices for perioperative cardiorespiratory function failure in ICU were analyzed.Left ventricular assist device (LVAD) was used in 3 patients by the cannulation of the left alritan and ascending aorta.The extracorporeal membrane oxygenation(ECMO) was established in 48 patients for postoperative cardiorespiratory function failure.The vencarterial bypass was established by cannulation of the right atrium in 41 patients and femoral artery and of venovenons in 2 patients,and of the right atrium and ascending aorta in 5 cases,lntra-aortic balloon pumping(I-ABP)was performed via the femoral artery either percutaneonsly by the Seldinger technique in 195 patients.The cardiac operations included coronary artery bypass grafting (n=170),coronary artery bypass grafting with romoldingof left ventricle (n = 22),coronary artery bypass grafting with valvular operation (n=10),valvular operation (n=27),heart transplantation(n=8),correction of congenital heart defects(n=6),aortic operations(n=2).The duration of circulatory support ranged from 4 to 451 hours.Correlative complications of 3 kinds of circulatory support device were compared and repair of ventricular septal perforation in the wake of acute myocardial infarction (n=1).Results Seventy-eight (31.7%) patients died.Seventy-one(28.9% ) patients devdoped various complications including infection(n=27),renal failure required renal rephcement therapy (n=27),re-exploration for bleeding(n=24),haemolysis(n=6),limb ischemia(n=15),neurological complications(n=6),oxygenator failure(n=7) Conchusions The improvement of management to reduce complications may result in improved outcomes of patients supported with circulatory support devices.

Objective To investigate the effect of the nuclear factor (NF)-κBp65 antisense oligonucleotide (ASODN) on NF-κB activity and expression of interleukin(IL)-6 in hepatic stellate cells (HSC). Methods The HSC were separated from rats and cultured. The toxicity of NF-κBp65 ASODN on HSC were detected by Trypan blue exclusion staining and the NF-κB activity was determined by EMSA. The expressions of IL-6 mRNA and protein were meaured by RT-PCR and ELISA, respectively. Results In vitro, no toxicity of ASODN on HSC was observed at the concentrations of 0. 001 to 1.0 μmol/L. NF-κB activity was increased after stimulating HSC with tumor necrosis factor (TNF)α, whereas it was weakened in a dose dependent manner when HSC were cultured with ASODN (concentration from 0. 001 to 1.0 μmol/L). At the same time, the expressions of IL-6 mRNA and protein induced by TNFα were decreased after transfected with ASODN at concentrations of 0.001- 1. 0 μmol/L in a dose dependent manner. Conclusion ASODN may specifically inhibit either the activiy of NF-κB or expression of IL-6, which provides the theoretical basis that ASODN may use to treat fibrosis of the liver.

Objective To explore the attitudes towards the Smoking Ban policy and the bias in different levels of related society sanctions so as to provide evidence for implementing anti-smoking measures in the public places.Methods A multi-univariate-multilevel logistic model was developed to find the relation between penalty attitudes and the covariates' effects.Results 74.6％ (3647/4892) and 61.2％ (2994/4892) of the residents agreed to punish either the managers of public places or to the smokers.The two kinds of attitude were associated (x2 =1253.45,P＜0.0001 ).Residents being female,aged between thirty and fifty-nine years old,having had higher than college education,being non-current smokers,with high scores on knowledge of tobacco control,tended to have the attitude of punishing the public place managers and smokers.However,those persons exposed to everyday secondhand smoke or being non-current smokers,tended to punish the smokers in the generalized Wald test.Conclusion There was strong evidence noticed that most of the residents in Guangzhou had supported the ‘tobacco control penalty'.Factors as age,sex,level of education received,knowledge on hazards of smoking,being current smokers and under secondhand smoke exposure were the influencing factors.Non-current smokers and those who exposed to secondhand smoke everyday,would prefer to take different penalties policies.

Objective To establish the bedside screening scale for cognition examination in systemic lupus erythematosus patients.Methods The modified mini-mental status examination(MMMSE)(revised by the Neurology Department of Hua Shan Hospital)was applied to examine the recognition function of SLE pa- tients.The results were compared with those of the traditional mini-mental status examination(MMSE).Results MMSE examination results showed that NPSLE score was lower than that of normal control group(P＜0.01),no significant difference was found between NPSLE patients and SLE control group(P＞0,05),and the completion time was longer than SLE control group and normal control group(P＜0.01);but no significant difference was found between SLE control group and normal control group.The result of MMMSE examination showed that the score of NPSLE group was lower than that of SLE control group and normal control group(P＜0.01),and the completion time was longer than SLE control group and normal control group(P＜0.01);but the score of SLE control group was lower than the normal control group,and its completion time was longer than normal control group,the difference was statistically significant(P＜0.01).Conclusion MMSE is the most widely used dementia scale,but it is not sensitive in demonstrating the impairment of recognition function.The several items we added to the MMMSE can detect recognition impairment more sensitively,and ean be very easily applied,costs less time(within 10 minutes).Therefore,it can be used for SLE bedside screening.
