BACKGROUND:In recent years, there are many animal studies and osteoblast studies on the anti-osteoporotic effects of puerarin, a kind of phytoestrogen. But few of them are reported on the effects of puerarin on osteoblasts in older patients with osteoporosis. OBJECTIVE: To observe the influence of puerarin on the proliferation ofin vitro cultured osteoblasts from older female patients with osteoporosis. METHODS:The older female patients with osteoporotic femoral neck fractures who underwent artificial femoral head replacement were included in this study. The femoral neck cancelous bone removed during the operation was colected. Primary cancelous bone osteoblasts were cultured using explant culture method. The cels were sub-cultured to the required amounts. Osteoblasts from the control group were cultured with culture medium without puerarin. Osteoblasts from the 0.01, 0.1, and 1 μmol/L puerarin groups were cultured with culture medium containing the corresponding concentrations of puerarin. After in vitro co-culture with different concentrations of puerarin for 1, 3, 5 days, the proliferation of osteoblasts was observed. RESULTS AND CONCLUSION:With the increase in the concentration of puerarin, the proliferative activity of
osteoblasts constantly increased at different time points (P < 0.05). At 3 days of culture, cel absorbance value in each group reached the peak level. These results suggest that 0.01, 0.1, 1μmol/L puerarin promotes the proliferation of osteoblasts in older patients with osteoporosis in a concentration-dependent manner.

OBJECTIVE:To investigate the effects of puerarin on bone mineral density around the femoral prosthesis of el-derly women after osteoporotic fracture artificial hip joint replacement. METHODS:99 elderly women after osteoporotic fracture artificial hip joint replacement were divided into control group(49 cases)and test group(50 cases)according to random number table. Control group received conventional treatment:calcium carbonate and vitamin D3+alendronate sodium+salmon calcitonin;test group was additionally given Puerarin injection 200-400 mg dissolved in Glucose injection 500 ml intravenously,qd,on the basis of control group. A treatment course lasted for 20 d,and both groups received 2 courses of treatment. The hip joint function score and bone mineral density around the femoral prosthesis of 2 groups were observed and compared after surgery,and the oc-currence of ADR was also observed. RESULTS:3 and 2 patients withdrew from control group and test group,respectively. 18 months after surgery,the patients with hip joint function score ranged 70-79 in test group was significantly less than in control group;the rate of excellent hip joint function score in test group was significantly higher than in control group,with statistical significance (P<0.05). 15 and 18 months after surgery,bone mineral density in R1-R5 range of Gruen range in test group was slightly higher than in control group,without statistical significance(P>0.05);bone mineral density in R6-R7 range was signifi-cantly higher than control group(89.58% vs. 69.57%),with statistical significance(P<0.05). The prosthesis loosening was not found in both groups,and ADR was also not found as fever,erythra,nausea,vomiting,headache,dizziness,etc. CONCLU-SIONS:For the use of puerarin in elderly women after osteoporotic fracture artificial hip joint replacement,puerarin can increase the periprosthetic femur bone mineral density with good safety.

AIM:To explore the effects of atorvastatin (Atorv) on atherosclerosis in streptozotocin (STZ)-in-duced diabetic apolipoprotein E knockout ( ApoE-/-) mice with fat-rich diet and the possible mechanism .METHODS:C57 mice served as control.ApoE-/-mice (n=34) fed with high-fat diet were randomly divided into ApoE-/-group, STZ-ApoE-/-group and STZ-ApoE-/-+Atorv group.Intraperitoneal injection of streptozotocin was performed to create di-abetic animal model .Blood glucose was determined by glucose oxidase method .Blood lipid levels were detected by enzymic method or selective homogeneous method .The plaque area in the thoracic aorta was measured by HE staining .The protein level of nicotinamide-adenine dinucleotide phosphate ( NADPH) oxidase subunit gp91phox in the thoracic aorta was deter-mined by Western blotting .The levels of reactive oxygen species ( ROS) in blood and thoracic aorta homogenates were de-tected by Fenton reaction and Griess reagent .Human umbilical vein endothelial cells ( HUVECs ) were isolated from healthy umbilical cords by collagenase I and cultured .ROS production was detected by flow cytometry .NADPH oxidase ac-tivity was measured using lucigenin assay .Effects of retinoid X receptor α( RXRα) on inhibition of oxidative stress by ator-vastatin were evaluated by RNA interference and plasmid transfection .RESULTS: (1) Compared with C57 group, the plaque areas of the thoracic aorta in ApoE-/-group were increased .No difference of the fasting glucose between the 2 groups was observed.The levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), thoracic aorta gp91phox protein and ROS in blood and thoracic aorta homogenates were higher in ApoE-/-group than those in C57 group.(2) Compared with ApoE-/-group, the plaque areas of the thoracic aorta in STZ-ApoE-/-group were further enlarged [(314.13 ±35.72) μm2 vs (215.88 ±34.19) μm2, P<0.05].The levels of blood glucose, TG, TC and LDL-C, thoracic aorta gp91phox protein and ROS in blood and thoracic aorta homogenates were higher in STZ-ApoE-/-group than those in ApoE-/-group (P<0.05).(3) Compared with STZ-ApoE-/-group, the plaque areas of the thoracic aorta in STZ-ApoE-/-+Atorv group were reduced [(217.47 ±24.56) μm2 vs (314.13 ±35.72) μm2, P<0.05].The levels of blood glucose , LDL-C, TC, HDL-C and TG showed no significant difference between the 2 groups.Thoracic aorta gp91phox protein level and ROS production in blood and thoracic aorta homogenates were lower in STZ -ApoE-/-+Atorv group than those in STZ-ApoE-/-group (P<0.05).(4) High glucose-induced increases in NADPH oxidase activity and gp91phox expression were significantly inhibited by atorvastatin (10-6 mol/L) in HUVECs.The inhibitory effects of atorvasta-tin on high glucose-induced ROS production and NADPH oxidase activation were largely impaired when the cells were trans -fected with RXRαsiRNA.However , the effect of atorvastatin was significantly strengthened when RXRαwas over-expressed in the HUVECs transfected with RXRαplasmid.CONCLUSION: Atorvastatin inhibits atherogenesis by depressing high glucose-induced oxidative stress in diabetic ApoE-/-mice with fat-rich diet.The anti-oxidative stress effect of atorvastatin is mediated by RXRα.

Objective To compare the importance of heart murmurs and transcutaneous oxygen saturation (SpO2)in screening neonatal congenital heart diseases(CHD),and to explore a reliable and easy-to-use method for the screening of CHD. Methods All infants (16 070 cases) born in Changzhou Maternal and Child Health Hospital from May 1 st 2011 to April 30 th 2013 were screened of CHD for heart murmurs and SpO2 . The screen-positive infants were divided into 3 groups:heart murmurs group,abnormal SpO2 group and mixed group. All screen-positive infants re-ceived cardiac color ultrasound to make a definite diagnosis of CHD,so as to compare the values of heart murmurs and SpO2 . Results Eight thousand seven hundred and ninety-nine boys and 7 271 girls were screened,in which the ratio was 1. 21:1. 00. One hundred and eighteen infants were screened positive,including 76 murmurs of which 45 were confirmed as CHD,28 with abnormal SpO2 of which 18 were confirmed and 14 mixed of which 13 were confirmed,so the confirmation rates were 59. 21%,64. 29% and 92. 86%,respectively. The diagnostic rate of CHD in mixed group was higher than other 2 groups,which had statistical significance(P=0. 045). The top three formation types of CHD were ventricular septal defect (VSD) (29/76 cases,38. 16%),patent ductus arteriosus (PDA) (13/76 cases, 17. 11%) and atrial septal defect (ASD) (11/76 cases,14. 48%). Conclusions The combination of heart murmurs and SpO2 was useful in increasing detection and decreasing misdiagnosis of CHD.

Objective To investigate the prevalence and the distribution of congenital heart disease(CHD) in Changzhou city.The clinical data of 106 CHD infants were reviewed,so as to provide some evidence for making CHD screening-evaluating-intervention system.Methods All infants(16 070 cases) born in Changzhou Maternal and Child Health Hospital from May 1st 2011 to Apr.30th 2013 were screened for CHD.The infants with CHD were followed up for one year periodically after discharge.Results One hundred and seventeen infants were screened positive,and 106 cases of them were diagnosed as CHD,and the detectable rate was 6.60‰.The top three incidence was VSD (2.18‰,35/16 070 cases),PDA(1.74‰,28/16 070 cases) and ASD(1.06‰,17/16 070 cases).Among them,81 cases were detected as cardiac souffle,and 48 cases as abnormal pulse oximetry.In 106 cases,97 cases were followed up and 9 cases did not receive follow-up.The close ratio were higher in ASD,PDA,VSD,which was 76.47％,64.29％,62.86％.The size of gap had an effect on close ratio,small gap of VSD,ASD and premature PDA were higher and medium and large gap and full-term infants were lower.Some serious type of CHD infants received operations,and others were still followed up.Conclusion The detectable rate of CHD among infants was identical to the average level of whole country.The follow-up study may improve the quality of the survival of CHD infants,and it is feasible to construct a system of screening-evaluating-intervention systcm of CHD.
