Objective To study effects of high dosage of atorvastatin in acute coronary syndrome(ACS)patients on high sensitive creactive protein(hsCRP)and atherosclerosis.Methods 126 cases with ACS were divided into A,B and C group.30 patients in A group were given atorvastatin 20mg per night,41 cases in B group were given atorvastatin 40mg per night,while the other 55 patients in C group were taken atorvastatin 40mg per night and tirofiban in the first 24 to 48 hours.The patients were followed 6 months by evaluating serum hsCRP concentration,measuring the intimal thickness in the carotid artery with color Doppler.Results After treatment for 6 months,the patients in the three groups showed significant decrease in hsCRP,however,the therapeutic group showed significant difference amony the three groups.Additionally,the B and C groups further showed significant decrease in intimal thickness.Conclusion Using high-dose atorvastatin and tirofiban not only lowers hsCRP significantly,but also benefit stability of atherosclerotic plaque in carotid artery,and to reduce cardiovascular events.

Objective To study the relationship between the expression of peroxisome proliferator-activated receptor? (PPAR?) mRNA and the severity of coronary lesions in coronary heart disease(CHD) patients. Methods 153 patients with CHD who had undergone coronary angiography were admitted, the expression of PPAR? mRNA in peripheral lymphocytes was assessed using RT-PCR. The severity of coronary artery lesions was analyzed, and the lesions of coronary artery were delineated. Results Compared with control, in CHD patients IRI BMI TC LDL-C were elevated and HDL-C decreased. Significant decrease in PPAR? mRNA was observed in CHD patients (0.40?0.12 vs 0.62?0.13, P

The anaerobic granular sludge from an Internal Circulation (IC) reactor of a paper mill wastewater treatment plant were seeded in an Anammox upflow anaerobic sludge blanket reactor. After 185 days operation, the reactor was finally started up by increasing the influent ammonium and nitrite concentrations to 224 mg/L and 255 mg/L, respectively, with volumetric nitrogen removal rate increasing to 3.76 kg/(m3·d). The physicochemical characteristics of the cultivated Anammox granules were observed by scanning electron microscope, transmission electron microscope and Fourier Transform infrared spectroscopy (FTIR). Results suggested that during the start-up course, the granular sludge initially disintegrated and then re-aggregated. FTIR spectra results revealed that the Anammox granular sludge contained abundant functional groups, indicating that it may also possess good adsorption properties. The ecological structure of the granular sludge, analyzed by the metagenomic sequencing methods, suggested that the relative abundance of the dominant bacterial community in the seeding sludge, i.e., Proteobacteria, Firmicutes, Bacteroidetes, significantly reduced, while Planctomycetes which contains anaerobic ammonium oxidation bacteria remarkably increased from 1.59% to 23.24% in the Anammox granules.

AIM:To observe the effect of B-HT933, a selective α2-adrenoceptor agonist, on lipopolysaccha-ride ( LPS )-induced TNF-αproduction in neonatal rat cardiomyocytes and to explore the underlying mechanisms . METHODS:The neonatal rat cardiomyocytes were cultured .The localization of α2A-adrenoceptor in the cardiomyocytes was examined by immunofluorescence staining .The cardiomyocytes were exposed to LPS or/and B-HT933 for different time.The level of TNF-αin the supernatants and the mRNA expression of TNF-αwere detected by ELISA and real-time PCR, respectively.In addition, LPS-associated signal molecules in the cardiomyocytes were also examined by Western blotting.RESULTS: Immunofluorescence staining showed that α2A-adrenoceptors were localized in the cardiomyocytes . LPS stimulated TNF-αproduction in the cardiomyocytes in a dose and time-dependent manner .B-HT933 pretreatment sig-nificantly inhibited the expression of TNF-αat mRNA and protein levels in LPS-treated cardiomyocytes .Furthermore, LPS exposure induced IκBαand p38 phosphorylation in cardiomyocytes and only IκBαphosphorylation was prevented by B-HT933 treatment.CONCLUSION:α2A-adrenoceptors are present in neonatal rat cardiomyocytes and its agonist B -HT933 inhibits LPS-induced TNF-αproduction in cardiomyocytes via suppressing IκBαphosphorylation .

Objective:To study the correlation between fatigue symptoms and living condition of liver transplant recipients after discharge from hospital, so as to provide reference basis for preventing postoperative fatigue symptoms in recipients.Methods:From September 2018 to December 2018, 280 liver transplant recipients were selected from the liver transplantation clinic of a grade-three hospital in Shanghai by convenience sampling method, and clinical data of the patients were obtained by questionnaire survey to analyze factors of the symptom of postoperative fatigue.Results:A total of 280 patients were included, among which 130 patients showed fatigue symptoms, accounting for 46.4%. The results of single-factor analysis showed that the postoperative survival days, gender, total time of exercise, body mass index, working status, mode of payment of medical expenses, Sleep quality, negative emotions, and nutritional risk all exert an influence on fatigue symptoms ( P<0.05). The results of multi-factor analysis showed that the total time of exercise during a week ( OR=0.674, 95% CI:0.512-0.887), postoperative survival days ( OR=0.993, 95% CI:0.989-0.997) and the score of negative emotion scale ( OR=1.484, 95% CI:1.157-1.902) had significant influence on fatigue symptoms in patients ( P<0.01). Conclusions:Postoperative survival days, exercise time and negative emotions are the main factors affecting fatigue symptoms. Medical staff should evaluate and manage patients' psychological and activity exercise to improve fatigue symptoms.

OBJECTIVE: To detect potential variant in an ethical Han Chinese pedigree affected with breast cancer. METHODS: The proband and her relatives were subjected to next-generation sequencing using a target capture sequencing kit containing 121 cancer-related genes. Candidate variants were selected by analysis of their type, frequency in population, and segregation with the phenotype. Candidate variant was verified by Sanger sequencing and TA cloning. RESULTS: A c.2013_2014ins GT variant was detected in the BRCA1 gene among all breast cancer patients from this pedigree but not among healthy females. The variant was not recorded in the 1000 Genome Project database or the Exome Aggregation Consortium (ExAC) database. The frameshifting insertion was predicted to form an premature stop codon in gene transcript and can give rise to a truncated protein. CONCLUSION The BRCA1 c.2013_2014ins GT variant probably underlies the pathogenesis of breast cancer in this Chinese pedigree.
