Cardiovascular disease is a severe threat to human health and life. Among many risk factors of cardiovascular disease, genetic or gene-based ones are drawing more and more attention in recent years. Accumulated evidence has demonstrated that the loss or mutation of ataxia telangiectasia mutated (ATM) gene can result in DNA damage repair dysfunctions, telomere shortening, decreased antioxidant capacity, insulin resistance, increased lipid levels, etc., and thus can promote the occurrence of cardiovascular risk factors, such as aging, atherosclerosis and metabolic syndrome. In this review, we discusses the possible mechanisms between ATM gene and cardiovascular risk factors, which could be helpful to the related research and clinical application.

OBJECTIVETo sum up the experience in diagnosis and treatment of Fournier's gangrene and find an optimal evaluation tool for its prognosis by comparing currently used prognostic scoring systems.
METHODSWe retrospectively analyzed 16 cases of Fournier's gangrene diagnosed and surgically treated in our hospital between 2004 and 2012. Using Fournier's Gangrene Severity Index (FGSI), Uludag Fournier's Gangrene Severity Index (UFGSI), Age-Adjusted Charlson Comorbidity Index (ACCI), and Surgical Apgar Score (sAPGAR) , we obtained the prognostic scores of the patients and made comparisons among different scoring systems.
RESULTSFGSI, UFGSI, ACCI, and sAPGAR were all clinically used scoring systems. Statistically significant differences were found in the scores of ACCI and UFGSI but not in those of FGSI and sAPGAR between the death and survival groups, with the maximum area under the ROC curve and minimum standard error for the ACCI score.
CONCLUSIONBoth ACCI and UFGSI are useful for evaluating the prognosis of Fournier's gangrene. However, ACCI is even better for its higher sensitivity and specificity and easier clinical collection.

Background Proliferative vitreoretinopathy(PVR) is a tissue repair prevention and treatment of PVR in clinic.Natural delayed release microballoons are therefore becoming a hot spot for its easy manipulation,large lading dose and long acting duration.Objective This study was to evaluate the effect of 5-fluorouracil natural delayed release microballoons on the prevention of PVR.Methods The lymphocytes were collected from clean pigment rabbit to prepare the 8×107/ml cell suspension with complete culture fluid.PVR models were established in 45 healthy pigment rabbits by intravitreal injection of lymphocyte suspension.The animals were randomly divided into 3 groups and 15 rabbits for each.0.1ml normal saline,10g/L or 20g/L 5-fluorouracil natural delayed release microballoons were injected into vitreous cavity respectively.PVR was graded on Fastenberg's method under the slit lamp in 1,2,4,8 weeks.The animals were sacrificed and retinas were obtained for the histopathological and ultrastructural examination in the eighth week after administration of drug.Results The numbers of eyes with different grades of PVR were significantly different among 3 groups in 1 week,2,4,8 weeks(P<0.05).The eye numbers with PVR was significant less in 20g/L Fu group than those of 10g/L Fu group and normal saline group(P<0.05).There was statistical difference in PVR ranking among these 3 groups in 8 weeks after injection of drug(H=46.795,P<0.05).The morphology and ultrastructure of retinas under the light microscope and transmission electron microscope were near normal in all of the three groups.Conclusion Implantation of 5-fluorouracil natural delayed release microballoons into vitreous cavity is effective and safe in preventing PVR in experimental model,and the therapeutic effect of microballoons with 20g/L 5-Fu is better.

Radical retropubic prostatectomy (RRP) has been one of the most effective treatments for prostate cancer.This study is designed to identify the related predictive risk factors for complications in patients following RRP.Between 2000 and 2012 in Department of Urology,Fudan University Shanghai Cancer Center,421 cases undergoing RRP for localized prostate cancer by one surgeon were included in this retrospective analysis.We reviewed various risk factors that were correlated with perioperative complications,including patient characteristics [age,body mass index (BMI),co-morbidities],clinical findings (preoperative PSA level,Gleason score,clinical stage,pathological grade),and surgeon's own clinical practice.Charlson comorbidity index (CCI) was used to explain comorbidities.The total rate of perioperative complications was 23.2% (98/421).There were 45/421 (10.7%),28/421 (6.6%),24/421 (5.7%) and 1/421 (0.2%) in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ respectively,and 323/421 (76.8%) cases had none of these complications.Statistical analysis of multiple potential risk factors revealed that BMI >30 (P=0.014),Charlson score ≥1 (P<0.001) and surgical experience (P=0.0252) were predictors of perioperative complications.Age,PSA level,Gleason score,TNM stage,operation time,blood loss,and blood transfusion were not correlated with perioperative complications (P>0.05).It was concluded that patients' own factors and surgeons' technical factors are related with an increased risk of development of perioperative complications following radical prostatectomy.Knowing these predictors can both favor risk stratification of patients undergoing RRP and help surgeons make treatment decisions.

Most Chinese medicine has good clinical efficacy and application. However, the material basis is vague for the lack of basic research, the value of Chinese medicine is hard to reflect for the low technology level and product quality is difficult to maintain for the quality control indicator selection is incorrect. Chinese medicine Jinfukang oral liquid is a typical product of Chinese medicines. Jinfukang oral liquid was selected as a model drug in this article. Based on the overall concept and systems theory of traditional Chinese medicine, the research idea and technology system for modern Chinese medicine secondary exploitation was formed. The system includes three parts, for the first, basic research to make clear the components structure and their action mechanism, for the second, technology upgraded to optimize process and improve the product quality, for the last, exploring the associated industry to form the industrial chain. The research ideas and technology system based on the material basis research and development of modern Chinese medicine, guided with component structure in Chinese medicine and aimed clinical needs. This research ideas and technology system provides strategies and methods for the development of modern Chinese medicine secondary exploitation.

OBJECTIVETo compare the dissolution characteristics of colloidal silica and porous silica as the solid dispersion carrier, with baicalin as the model drug.
METHODThe baicalin solid dispersion was prepared by the solvent method, with colloidal silica and porous silica as the carriers. In the in vitro dissolution experiment, the solid dispersion was identified by scanning electron microscopy, differential scanning and X-ray diffraction.
RESULTThe solid dispersion carriers prepared with both colloidal silica and porous silica could achieve the purpose of rapid release. Along with the increase in the proportion of the carriers, the dissolution rate is accelerated to more than 80% within 60 min. Baicalin existed in the solid dispersion carriers in the non-crystalline form.
CONCLUSIONThe release behaviors of the baicalin solid dispersion prepared with two types of carrier were different. Among the two solid dispersion carriers, porous silica dissolved slowly than colloidal silica within 60 min, and they showed similar dissolutions after 60 min.

Baicalin extremely fine powder was made by using ball-mill and the effect of micronization on the micromeritics properties of baicalin was studied and analyzed. The microstructures of baicalin ordinary and extremely fine powder were compared by scanning electron microscope, differential scanning calorimeter and X-ray diffraction and the powder characteristic of them was investigated. The hygroscopicity was studied. The effect of micronization on the dissolution of baicalin was investigated. The results showed that the chemical constituents of baicalin were not changed after micronization with better compressibility. It was confirmed that micronization technology had a certain application value in promoting the insoluble component of baicalin absorption with higher dissolution.
