Objective To improve short-and mid-term surgical outcomes ofter the tricuspid ring annuloplasty,and to provide theoretic basis for strategy making among patients with tricuspid regurgitation secondary to left-sided heart diseases.Methods Tricuspid regurgitation secondary to left-sided heart diseases ( including mitral valve diseases and aortic valve diseases) were treated by using tricuspid ring annuloplasty techniques.Patients'age averaged (47.3 ± 12.0) years old,there were a total of 84 female patients(53.2％ ).The average systolic pulmonary pressure was (53.4 ± 19.8) mm Hg.From August 2002 to December 2007,a total of 158 consecutive patients underwent tricuspid ring annuloplasty in Fuwai Cardiovascular disease Hospital.Among this group of patients,there were 66 mild tricuspid regurgitation(41.8％ ),54 moderate(34.2％ ),and 38 severe tricuspid regurgitation(24.0％ ).The average age was (47.3 ± 12.0) years old and female accounted for 53.2％ of the whole cohort.The indications for the tricuspid ring annuloplasty included:moderate to severe tricuspid regurgitation or moderate to severe pulmonary hypertension ( systolic pulmonary hypertension ＞40 mm Hg).In the current study,the ring annuloplasty techniques were modified in the following aspects:selection of undersized ring and partial fixation of tricuspid septal segment.In all the patients,we chose Cosgrove-Edwards ring for tricuspid annuloplasty.The surgical outcomes were evaluated through multivariate regression and Cox analysis.Results Compared with moderate and severe tricuspid regurgitation groups,mild regurgitation group had the smallest ring diameter,mild group ( 38.2 ± 4.9 ) mm,moderate group(47.0 ± 11.6 ) mm,severe group(44.5 ± 8.9) mm,P ＜0.001.No significant differences were noted in terms of ejection fraction among three groups (0.59 ± 0.08,0.59 ± 0.06 and 0.58 ± 0.09,P =0.73 ).Compared with mild and moderate tricuspid regurgitation groups,severe regurgitation group had the highest systolic pulmonary pressure.The diameter reduction was most significant in severe regurgitation group,diameter reduction in mild,moderate and severe regurgitation groups were ( 12.4 ±5.6) mm,(20.8 ± 11.5 ) mm,( 18.6 ± 8.3 ) mm,respectively,P ＜ 0.00 1.An in-hospital death occurred in moderate regurgitation group.157 patients discharged alive.The median follow-up time was 49.1 months.During follow up,three moderate to severe regurgitation occurred,among which one was in moderate regurgitation group,two in severe regurgitation group ( P =0.06).There were three deaths in mild regurgitation group,two in moderate regurgitation group,and four in severe regurgitation group.No significant differences were found in terms of mid-term morality,P =0.10.Conclusion For patients with tricuspid regurgitation secondary to left-sided heart diseases,the mid-term outcomes of modified Cosgrove-Edwards ring annuloplasty were satisfactory.The taking home messages include:positive recommendation for patients with pulmonary hypertension to accept tricuspid annuloplasty,use of undersized ring,and partial fixation of septal segment.

Objective:To compare the osteogenic differentiation of dental pulp stem cells(DPSCs)induced by osteopontin(OPN)and mineralizing culture medium(MCM).Methods:DPSCs were cultured with OPN(OPN group)and MCM(MCM group)respectively. The morphology of the DPSCs were observed under inverted microscope.The mineralize nodules were observed by alizarin red staining. RT-RCR was used to detect the mRNA expression of bone sialoprotein (BSP),Runt-related transcription factor 2(Runx-2),osteocal-cin(OCN)and collagen-1(Col-1).Results:Similar number of mineralized nodules was found in the 2 groups(P >0.05)after 28 day culture.The mRNA expression level of BSP gene in OPN group was higher than that in MCMgroup(0.864 ±0.112 and 0.514 ±0.068, P <0.05),while the expression level of Runx-2 gene in OPN group is lower than that in MCMgroup(0.186 ±0.017 and 0.324 ±0. 058,P <0.05).The expression level of Col-1 and OCN genes in both groups were similar(P >0.05).Conclusion:The capabilities of OPN and MCMin inducing osteogenic differentiation of DPSCs are similar.

Objective: To explore the effect of low-level laser irradiation (LLLI) preconditioning on milieu of infarcted myocardium in experimental rats.
Methods: The myocardial infarction (MI) model was established by left anterior descending (LAD) artery ligation in female rats. 3 weeks later, the qualified MI rats were randomly divided for 3 groups: ① LLLI preconditioning group, the rats received thoracotomy for LLLI by a 635nm, 5mW diode laser with the energy density of 0.96 J/cm2 for 150 seconds, n=26. ② Control group, the rats received thoracotomy for daylight irradiation, n=27. ③ Sham operation group, the rats received thoracotomy without LAD ligation, n=24. The Expressions of myocardial vascular endothelial growth factor (VEGF), glucose-regulated protein 78 (GRP78), superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluate by real time-PCR, Western blot analysis and other relevant laboratory test at 1 hour, 1 day and 1 week after treatment. The myocardial cell apoptosis was examined by TUNEL staining, and left ventricular function was detected by echocardiography.
Results: LLLI preconditioning obviously increased the myocardial VEGF, GRP78 expression and SOD activity, decreased MDA production; while it could not really improve the myocardial cell apoptosis at peri-infarcted area and left ventricular function in experimental rats.
Conclusion: LLLI preconditioning may improve the milieu of infarcted myocardium via decreasing the oxidative stress in experimental rats.

Objective To evaluate the influence of grape seed proanthocyanidin extract (GSPE) on sunburn cell formation and p53 protein expression induced by acute ultraviolet injury. Methods Ten volunteers were enrolled in this study. The buttock region served as the exposed region. Four areas were randomized and delineated on the buttock: one area (control area) received no exposure or product, the other 3 areas were exposed to two minimal erythema doses (MED) of simulated solar radiation (SSR) for 3 days. Of the 3 exposed areas, one area (SSR) received no product before exposure, one area (SSR + Veh) was pretreated with vehicle, the third area (SSR + GSPE) with the samples of GSPE. GSPE or vehicle was applied 30 minutes before each exposure at 2 μL/cm2. Skin biopsy was performed 24 hours after the last exposure, and skin specimens were subjected to hematoxylin eosin (HE) staining and histochemical analysis for p53 protein. Results There was a statistical difference in the number of sunburn cells per high power field (×200) between SSR sites and SSR + GSPE sites (29.8±11.1 cells vs 2.2±0.2 cells, P<0.01). A significant decrease was noticed in the account of p53 protein-positive cells per high power field (×200) in SSR + GSPE sites com-pared with the SSR sites (4.6±0.7 cells vs 19.3±3.4 cells, P<0.05). Conclusion GSPE exerts a poten-tial protective effect against acute ultraviolet injury and can serve as a natural sunscreen.

It's been confirmed that acupuncture-moxibustion is effective in treating primary dysmenorrhea, and the efficacy is closely related to the intervention time. By summarizing the latest research progress on real-time intervention and pre-intervention of acupuncture-moxibustion in treating primary dysmenorrhea, this articlewas to discuss about the effect of intervention time on the efficacy in treating primary dysmenorrhea and thus to provide evidence to choose the optimal intervention time. It brought up that real-time intervention of acupuncture-moxibustion can produce a significant analgesic effect in treating primary dysmenorrhea, while pre-intervention of acupuncture-moxibustion presents its advantages in generally regulating the body function. Therefore, the treatment of primary dysmenorrhea should combine real-time intervention and pre-intervention of acupuncture-moxibustion to enhance the clinical efficacy.

Objective: To assess the trend of statin application for in-hospital acute myocardial infarction (AMI) patients with its impact factors in eastern urban China from 2001 to 2011. Methods: A 2-stage random sampling design was performed to extract representative AMI sample patients. In the ifrst stage, a simple random-sampling was used to identify participating hospitals. In the second stage, a systematic sampling was conducted in 2001, 2006 and 2011 to select the cases from participating hospitals, to take medical records and clinical information for calculating the in-hospital statin application rate. The impact factors for statin application was assessed by multi Logistic regression model with generalized estimating equations. Results: A total of 5940 AMI records from 32 hospitals were enrolled. From 2001 to 2011, the in-hospital statin use rate increased from 46.0% in 2001 to 82.2% in 2006 and to 93.7% in 2011,P<0.001 for trend. Multi Logistic regression analysis indicated that the patients with LDL-C>3.37 mmol/L were more likely to receive statin therapy than those with LDL-C<1.81 mmol/L (OR=1.59, 95% CI 1.10-2.30,P=0.013); the patients with chest pain at admission (OR=1.82, 95% CI 1.14-2.91, P=0.012), combining hypertension (OR=1.44, 95% CI 1.02-2.03,P=0.038), with in-hospital PCI (OR=2.99, 95% CI 1.71-5.23, P<0.001) were also more likely to receive statin therapy. The application rate of statin was reduced by reduced LDL-C level accordingly and the patients without LDL-C examination, accounting for 21.3%, had the lowest statin application rate. Conclusion: Statin therapy for in-hospital AMI patients was dramatically increased from 2001 to 2011 in eastern urban China and the guideline was rapidly popularized in clinical practice. However, the improvement has been needed especially in patients without LDL-C examination or with low LDL-C levels; we emphasize that AMI patients should receive statin therapy regardless their LDL-C levels.

Objective: Based on nationwide cardiovascular surgery registry database, to analyze the current status and future development of minimally invasive cardiovascular surgery (MICS) in China.
Methods: There were 45 institutions from 19 provinces nationwide involved in Chinese cardiovascular surgery technique registry study. A total of 16480 adult patients with cardiovascular surgery from 2010-09 to 2012-03 were divided into 2 groups, Conventional surgery group, n=14503 and MICS group, n=1977. The basic clinical conditions were analyzed and compared between 2 groups in order to explore the current status and future development of MICS in China.
Results: Compared with Conventional surgery group, the patients in MICS group had the younger age, better and stable pre-operative condition. In MICS group, compared with 4 other common procedures, the patients who received hybrid procedure had obviously shorter cardiopulmonary bypass (CPB) time, aortic occlusion time, ventilator using time, ICU and in-hospital stay time, meanwhile decreased post-operative drainage volume;except for Robotic surgery, it required less red blood cells and plasma at during and post-operative time, all P<0.01. There were 12 (0.6%) in-hospital death in MICS group, the total complication rate was at 4%.
Conclusion: MICS are widely used in China, its short-term safety and efifcacy are conifrmed. Upon cardiovascular disease spectrum changing, the MICS procedures will be adjusted accordingly.
