Objective To summarize the ruptured types and surgical treatment experience for rupture of aortic sinus aneurysm. Methods Nineteen cases with aneurysm of aortic sinus were retrospectively analyzed. There were 10 cases with ventricular septal defect,6 cases with aortic valvular incompetence,6cases with other diseases,2 cases complicated by infective endocarditis. All cases underwent operational treatment. Results There were 15 cases of right aneurysm of aortic sinus,including 12 cases among them ruptured into right ventricle,3 cases rupture was penetrated into right atrium.There were 3 cases of null aneurysm of aortic sinus,including 1 case among them ruptured into right ventricle,2 cases ruptured into right atrium. There was 1 case of left aneurysm of aortic sinus, which ruptured into left ventricle. No operative death occurred in all, 1 case with aortic regurgitation light to moderate,and all cases were recovered.Conclusions The right aneurysm of aortic sinus is the most common types,and always rupture into right ventricle. It is important that aneurysm of aortic sinus should be operated as early as possible in order to avoid losing the chance of operation, particular in the patients complicated by infective endocarditis.

Objective To study the effects of PM2.5 and PM10 of dust storm on the secretion of nitrogen oxide(NO), interleukin-8 (IL-8) and tumor necrosis factor-?(TNF-?)in the alveolar macrophages(AM)of rat in vitro. Methods PM2.5 and PM10 were collected during dust storm period in the urban area of Beijing. The tested cells were primary cultured alveolar macrophages. Cytotoxicity of the particles was measured by MTT assay. The content of NO was determined using Griess reagent. The levels of cytokines IL-8 and TNF-? were determined using radioimmunity assay. Results After treatment for 24 h, PM2.5 and PM10 caused cytotoxicity to AM and the survival rate of the cells was decreased with the increasing exposure dose of the dust to the rats and the survival rate of the cells in the high dosage group was 80% of the control group. At concentrations of 20～150 ?g/ml, PM2.5 and PM10 increased the secretion of NO, TNF-? and IL-8 in AM in a dose-dependent manner. The cytotoxicity of PM2.5 was stronger than that of the PM10 at the same concentration, while the effects on the increasing secretion of NO, IL-8 and TNF-? induced by PM2.5 was smaller than that of the PM10. Conclusion PM2.5 and PM10 of dust storm could induce the secretion of inflammatory factors NO, IL-8 and TNF-? in rat AM.

In recent years, the cases of prenatal paternity testing gradually increased in forensic practice. The traditional prenatal paternity analysis can be performed only after invasive sampling of chorionic villi or amniotic fluid, which can result in a risk of miscarriage. The existence of circulating cell-free fetal nucleic acid in maternal plasma has brought new opportunities for the noninvasive prenatal paternity testing. In this paper, the research situation and application prospect of circulating cell-free fetal nucleic acid in maternal plasma in prenatal paternity testing are reviewed.

In this paper, the herbal textual research, historical evolutions in Pharmacopoeia, chemical composition, pharmacology and toxicology, processing and quality control of Typhonii Rhizoma were summarized in detail, so as to provide the references for the rational development and utilization of Typhonii Rhizoma.

Aim To explore the inhibition of Sinica Maxim′s extract( CSME) on resistant infections of burn wounds,such as the methicillin-resistant staphylococcus aureus ( MRSA ) , resistant pseudomonas aeruginosa (RPA) and resistant escherichia coli(RECO). Meth-ods The resistant strains were cultured by MH agar plates. After resistance genes of quality control strains were extracted and appraised, such as mecA, mexB, merA, qacE△1-sull, tnpU/A and mexB, etc, and then,some projects of CSME were detected,such as the antibacterial spectrum, the minimum inhibitory con-centration(MIC), different concentrations of sensitive rate and inhibition curves, etc. Finally, these results were compared with the inhibitory effects of some anti-biotics to determine the sensitivity rates of CSME. Re-sults The MIC of CSME was 62. 5 ,125 ,250 g · L-1 respectively on the MESA, RPA and RECO. The inhi-bition rates of CSME appeared concentration-dependent on these three kinds of resistant bacteria,and the inhi-bition rates of the multi-concentration CSME on RECO were significantly lower than on MRSA and RPA ( P<0. 05). While in MIC,the resistance rates of MRSA on carbenicillin, cefazolin, erythromycin were significant-ly higher than those of CSME(P<0. 05); The inhibi-tion zones of CSME were significantly smaller than those of ceftriaxone, cefepime, imipenem, but greater than those of other antibiotics( P<0. 05 ); The inhibi-tion zones of CSME on RPA were significantly smaller than those of carbenicillin, and greater than those of other antibiotics ( P <0. 05 ) . The inhibition zones of CSME on RECO were significantly smaller than those of ceftriaxone,cefepime,imipenem,ciprofloxacin,nitro-furazone,and greater than those of other antibiotics ( P<0. 05 ) . Conclusions CSME has a significant inhi-bition on burn wound infection with these three kinds of resistant bacteria,such as MRSA,RPA and RECO. It is prompted that CSME could become one of the effective drugs to control burn wound infections with multi-re-sistant strains.

OBJECTIVE:To provide reference for drug production,parchase and use in local governments,health care depart-ment,hospitals,manufacturers and sales enterprises,etc. METHODS:By consumption sum sorting method,the information of 14 categories and key types in 34 hospitals from Chongqing area during 2012-2014 were analyzed statistically such as sales,produc-tion manufacturers. RESULTS:The consumption sum of 34 hospitals from Chongqing area increased by 15%-17% during 2012-2014. The consumption sum and proportion of anti-infective drugs showed a downward trend,decreasing by 3.28%. Those of respi-ratory system drugs and anti-tumor drugs had the largest increase,with increasing rate of 79.01% and 69.39%,respectively. Do-mestic drugs accounted for about 73% market share,and sales of imported drugs increased more than domestic and joint-stock drugs,increasing by 40.17%. Among 6 Chongqing pharmaceutical manufacturers on the top 100 consumption sum shortlist,total consumption sum of 3 manufacturers had increased;the consumption sum of top 10 foreign pharmaceutical manufactures increased year by year. CONCLUSIONS:The consumption sum of drugs is increasing in Chongqing area. Anti-infective drugs accounted for less than 16%,which is the achievements of clinical application of antibiotics special rectification activities for 3 years. Both respi-ratory system disease and malignant tumor have high incidence in Chongqing area. Domestic drugs still are main types in hospital. Foreign manufacturers develop well in China,but Chongqing pharmaceutical manufacturers show unsatisfactory development pros-pect.
