Objective To understand and raise the level of osteopomsis-relied knowledge, attitudes and behaviors for prevention and treatment of osteoperosis(OP)in residents of a community. Methods A survey was performed with a questionnaires method targeting at the elderly residents in Changfeng community.The survey was conducted with a specifically designed questionnaire,followed by a second survey.during which health edueafion was stressed.Data were analyzed with SPSS 11.0 software. Results In 3524 residents.3367 responded positively.The ratio of male to female was 1:2.10.The average age of the respondents was 61.34 years.They demonstrated a low level of OP KAP.76.72% of them heard the term of OP,60.11% had a correct judgment of their own bone heahh,42.26% knew the cause of OP.and 37.75% understood the diagnostic method of OP.The level of OP KAP varied in different groups of targeted residents.Of all the questions.the understanding of the diagnosis ranked the lowest.2281 people participated in the second survey,which showed improvement in their OP KAP.The difference was statistically significant.1439 people auended the consultation.99.86% of them considered the activities necessary,96.92% expressed their satisfaction,and 98.54% planed tO take measures to improve their bone health.Conclusion The poor understanding of bone heaith status and the knowledge about prevention and treatment of OP is why it is widely spread in the modem society,which however Call be improved by education.

Objective To investigate the regulatory effect of adrenomedullin (AM) on the cell-cell contact formation of podocytes and the possible mechanism.Methods Podocytes were treated with AM (10-7 mol/L),AM combined with a PKA inhibitor H89 (10-4 mol/L),and forskolin (10-5 mol/L) as positive control respectively for 12 hours.Immunofluorescent staining was applied to observe the distribution of cell adhesion molecules and actin-associated proteins.Western blotting assay was used to assess their protein levels.Rho GTPases activity was analyzed by GST-pull down assay and their protein levels were tested by Western blotting.Results AM induced the redistribution of adhesion molecules,actin-associated proteins as well as the F-actin at cell-cell contacts between podocytes.This effect was similar to that of forskolin and could be blocked by H89.The levels of those proteins did not change significantly (P ＞ 0.05).AM up-regulated the activities of RhoA,Rac1 and Cdc42 (P ＜ 0.05),which were partially blocked by H89.The protein levels of Rho GTPases showed no difference compared with the control (P ＞ 0.05).Conclusions AM may promote cell-cell contact formation of podocytes,probably through enhancing the activity of Rho GTPases and then resulting in the redistribution of adhesion molecules,actin-associated proteins and F-actin,which is partially mediated through cAMP-PKA signaling pathway.

Objective To investigate the effects of tanshinol on the proliferation,apoptosis and NF-?B activation in rat hepatic stellate cells(HSCs) after IL-1? inducement,and to elucidate the anti-fibrotic molecular mechanisms of tanshinol.Methods The rat HSCs was isolated with collagenase in situ liver recirculation perfusion and cultured in vitro.The cells were divided into 5 groups: normal control,IL-1? treatment group(10 ng/ml),and tanshinol group 1,2 and 3.The later 3 groups were pretreated with tanshinol at the concentrations of 0.062 5,0.125 and 0.25 mmol/L respectively followed by 10 ng/ml IL-1? treatment 1 h later.MTT colorimetric assay was used to detect the proliferation of HSCs.AO/EB immunoflurorescence microscopy and combination Annexin-V-FITC/PI double-labelimmunofluorescence with flow cytometer were employed to examine the apoptosis of HSCs.Synthesis and secretion of collagen Ⅲ were detected by the quantitative immunocytochemical assay and ELISA respectively.The amounts of cytoplasm p-I?B? and NF-?B p65,and nuclear NF-?B p65 in HSCs were determined by Western blotting.Immunocytochemical staining and Western blotting were used to observe nuclear translocation of NF-?B p65.Results IL-1? increased the proliferation of HSCs(P

Objective To observe the intervention with electroacupuncture(EA) through regulating protein kinase(MAPK/ERK) pathway for cerebral ischemia rats.Methods SD rats were randomized into pseudo-operation group,model group and EA group.And the three groups were divided into 2-hour,one-day and 3-day subgroups according to the observation time.Focal cerebral ischemia(FCI) rat models were established by middle cerebral artery occlusion(MCAO) with heat-coagulation method.EA group received EA on Baihui(GV20) and Dazhui(GV14),qd,for 2 hours,one day and 3 days respectively.The learning and memory abilities of the rats in Y maze test and their neuroethological score were observed.Immunohistochemical method was used to observe the expression of phosphorylated extracellular signal-regulated kinase(p-ERK) after ischemia in CA1 area and CA3 area.Results In the model group,the neuroethological score was markedly increased,time for arriving the safe area in Y maze was prolonged(P

Objective To observe the curative effect of Rougan Granules on rats hepatocirrhosis induced by carbon tetra- chloride(CCl_4)with 10 % alcohol and high fat feed.Method The rat model was established by gastric garage of CCh (CCl_4:salad oil=1:1)1 mL/kg twice a week for two weeks,and with 10 % alcohol as drinking water,high fat feed as food.After administration of CCl_4,the rats were divided into 5 groups:the model group,high-,medium-and low-dosage of Rougan Granules groups,the eolchicine group.And normal control group was also set up.After adminis- tration for 6 weeks,hyaluronic acid,typeⅣcollagen and typeⅢprecollagen in serum were measured and liver histopathol- ogy examination was done.Result The contents of hyaluronic acid,typeⅣcollagen and typeⅢprecollagen in model rats were increased significantly,while Rougan Granules could decrease those increase significantly.Liver histopathology exami- nation showed medium or high fatty degeneration of hepatic cell,obvious hyperplasia of fibrous tissue with fibrous distance broaden and pseudolobuli formed in model group,but in Rougan Granules group the general pathological changes of liver were less.Conclusion Rougan Granules have an effect of experimental anti-hepatocirrhosis in rats.

Objective To study the mechanism of pulmonary injury and protective effect of modified ultrafiltration on lung function in infant open heart surgery.Methods According to the wishes of parents,40 cases of congenital heart disease were divided into without modified ultrafiltration control group (C) and modified ultrafiltration group (M),and parents signed informed consent.The cardiopulmonary bypass (CPB) was used without ultrafiltration in Group C,while with modified ultrafiltration in group M.The pneumodynamic parameters and C3a,C5a,TXA2,LT were measured at specific time points.Results The static pulmonary compliance (Cstat) and oxygen index (OI) were lower,and alveolar-arteria oxygen difference (AaDO2) was higher after CPB in the two groups(P ＜ 0.05).At T3,T4 and T5 time points,the Cstat and OI in Group M was higher than that in Group C; AaDO2 in Group M was lower than that in Group C (P ＜0.05).The levels of C3a and C5a were lower after CPB in the two groups; levels of TXA2,LT were higher after CPB in the C groups.At T2,T3,T4 and T5 time points,the TXA2 and LT in Group M were lower than that in Group C(P ＜0.05).Conclusions The pulmonary injury in pediatric open heart surgery may be concerned with the the alexin(C3a,C5a) activation and I/R.The level of C3a and C5a was considered earlier index of inflammatory reaction and pulmonary injury.Modified ultrafiltration improves pulmonary function due to elevating coloid osmotic pressure and degrading the plasma level of TXA2,LT.

OBJECTIVE: To investigate the effects of Erxian Decoction (EXD), a traditional Chinese compound herbal medicine and its separate prescriptions such as Wenshen Yijing Recipe (WSYJR, a recipe for warming kidney and replenishing essence), Ziyin Xiehuo Recipe (ZYXHR, a recipe for nourishing yin and dispersing fire) and Tiaoli Chongren Recipe (TLCRR, a recipe for regulating thoroughfare and conception vessels) and some extracts from EXD on the levels of LH and FSH in the primary cultured anterior pituitary cells from female rats. METHODS: EXD, its separate prescriptions and traditional Chinese herbal extracts from EXD were added directly to the incubators. The levels of LH and FSH were tested by radioimmunoassay. RESULTS: The levels of LH and FSH in the supernatant of anterior pituitary cells treated by EXD or its separate prescriptions including ZYXHR and TLCRR were increased significantly as compared with those in the blank control. There was a tendency for stimulating the secretions of LH and FSH in the WSYJR-treated group too. Dimethyl sulfoxide as the solvent of icariin and curculigoside could interfere with the results. CONCLUSION: EXD and its separate prescriptions such as ZYXHR and TLCRR can increase the levels of LH and FSH significantly.

Objective The use of targeting therapy for the treatment of gastric glandular cancer has been a hot topic in recent years. This study aims to clarify that through what ways the histone deacetylase inhibitor MS-275 completes its selectively killing effect on gastric glandular cancer cell line SGC-7901. Methods SGC-7901 cells and GES-1 cells were respectively cultured for 24h, with(10-100) μmol/L concentrations of MS-275. (1) The survival rate of SGC-7901 cells, GES-1 cells and the normal cells were analyzed by WST-1; (2) The change of the mitochondrial membrane potential in SGC-7901 was estimated by flow cytometry;(3) The expression levels of p21, p27, p57, cyclinB1, cyclinD1 were determined by Western blot and PCR methods. Results (1) MS-275 could decrease the survival rate of SGC-7901 cells, the effect was significantly enhanced with the increasing of the concentration (P<0.05), but MS-275 showed no obvious effect on normal gastric mucosa epithelial cells GES-1; (2) MS-275 treatment could decreased the mitochondrial membrane potential of SGC-7901 cells (P<0.05); (3) MS-275 treatment could increase the relative contents of p21, p27, p57 genes and their protein and, at the same time, decrease the relative contents of CyclinB1 and CyclinD1 (P<0.05). Conclusion MS-275 treatment can selectively kill gastric glandular cancer cells SGC-7901 through several possible ways, such as inducing mitochondrial apoptosis and regulating the expression levels of cell cycle-related genes and proteins.

Objective To assess the treatment outcomes of anterior segment optical coherence tomography(OCT) assisted excimer laser phototherapeutic keratectomy (PTK) for fungal corneal ulcer.Methods Twenty-four patients (24 eyes) suffered from fungal corneal keratitis were collected by a retrospecive chart review with at least 6 months of follow-up data available.All corneal ulcer depth did not exceed 1/3 corneal thickness and were resistant to local and systemic medication therapy for at least 1 week.Patients were divided into 2 groups.14 patients with 14 eyes were taken PTK and 10 patients with 10 eyes were treated with lamellar keratectomy.Follow-up time was at least 6 months.Visual acuities,corneal thickness,confocal microscope,healing of the epithelial defect and inflammation and complications were recorded.Results The postoperative visual acuity in two groups were significantly improved,visual acuity of PTK treatment group improved significantly better than the control group (P ＜ 0.05).Healing time of PTK treatment group (19.43 ± 5.68) days was shorter than that of the control group (34.40 ± 5.38) days,the difference was statistically significant (P ＜0.05).There was no significant difference in the residual central corneal thickness between the PTK treatment group and the control group (P ＞ 0.05).Residual mycelium after operation in the treatment group was significantly decreased than that of control group.Healing time of epithelial in PTK treatment group (4.0 ± 1.1) days was shorter than that of the control group (6.20 ± 1.39) days,the difference was statistically significant (P ＜ 0.05).There was no corneal dilation in two groups.No recurrence in PTK treatment group was occurred.3 cases in control group had recurrence after 6 months,drug control was effective in 1 case,and other 2 cases undertook corneal transplantation.Conclusion Anterior segment OCT assisted PTK for corneal ulcer can effectively clear the lesion,accelerate epithelial healing,provide a new choice for the treatment of early superficial fungal corneal ulcer.
