Patients diagnosed to have acute coronary syndromes( ACS) were included in the study. All ACS patients were divided into non-diabetes group(40 cases) and diabetes group(80 cases) . Blood coagulation function was de-termined for all patients. In the diabetes group eighty patients were randomly divided into ticagrelor group (48 ca-ses) and clopidogrel group (32 cases) . After 5 days′treatment, platelet function was detected. Our study aimed to examine the effects of ticagrelor and clopidogrel on the platelet function.

Objective To explore the telomere length (TL) in buccal cells and its possible implications for long-lived families of Zhuang nationality in Bama area of Guangxi.Methods Relative TL in buccal cells from Bama long-lived families (BLF,n=1250) was determined by real time PCR and compared between Bama non-long-lived families (BNLF,n=556) and Pingguo longlived families (PLF,n=630).All participants were Zhuang ethnic.Results The TL in buccal cells was negatively correlated with age (R=-0.215,P=0.000) and was independent of sex in all subjects (n=2436).There were no significant differences in TL between males and females in different of ages in BLF (all P>0.05).Similar tendency was observed in most but not all age groups in the two other families.The TL was significantly longer in BLF aged over 65 years (the first offspring of the longlived individual) than in BNLF aged over 65 years (1.969 vs.1.622,P=0.004) and the TL of BLF aged over 90 years was comparable to that of BNLF aged over 65 years (1.662 vs.1.622,P=0.955),which indicating that the offspring of long-lived individuals inherited longer TL from their parental generation.Conclusions Telomere length is shorten with aging in long-lived families in Bama area.The TL of BLF has a tendency of inheritance,which may be one of the mechanisms of longevity in Bama area.

Objective To investigate the bacterial resistance of clinical isolates collected in Tongling area. Methods Antimicrobial susceptibility test was conducted by Kirby-Bauer method.All the data were analyzed with WHONET 5.5 software.Results A total of 3 092 clinical isolates were collected during 2012,of which gram negative organisms and gram positive organisms accounted for 76.3% (2 359/3 092)and 23.7% (773/3 092),respectively.MRSA and MRCNS accounted for 50.9% of S.aureus and 73.0% of coagulase negative Staphylococcus,respectively.MRSA and MRCNS showed higher resistance to gentamicin,ciprofloxacin and erythromycin.No vancomycin-or teicoplanin-resistant strains of Staphylococcus spp.were found.No vancomycin-or teicoplanin-resistant strains of E.faecalis were found.Some E.faecium strains were resistant to vancomycin and teicoplanin.About 52.1% of E.coli isolates and 42.1% of Klebsiella isolates produced extended-spectrumβ-lactamases (ESBLs).Imipenem-or meropenem-resistant strains of K. pneumoniae were found. The percentage of P.aeruginosa strains resistant to amikacin, cefoperazone-sulbactam and cefepime was 3.4%,14.0% and 17.7%,respectively.More than 70% of Acinetobacter spp. strains were resistant to all the antibiotics tested except minocycline and cefoperazone-sulbactam,to which 42.1%and 4.4% of the strains were resistant.Conclusions The antibiotic resistance of clinical bacterial isolates is growing. The spread of multi-drug or pan-drug resistant strains in a specific region poses a serious threat to clinical practice.We should pay more attention to resistance surveillance and the rational use of antibiotics.

ObjectiveTo investigate clinical features, correlative factors and prognosis of senile coronary heart disease accompanied with depression.MethodsFifty two senile patients of coronary hart disease with depression were selected for the observation group, sixty cases without depression as control group. Clinical features, family conditions, society factors and Holter report (supervision) of two groups were analyzed.ResultsClinical features such as severe dyssomnia, anxiety agitation, emotion depressing, loss of interest, feeling waste and sense of guilty in patients of observation group were significant different with those in control group. The rate of family harmoniousness and society supporting between patients of two groups were significantly different. The incidence of ventricular arrhythmias, atrial arrhythmia and myocardial ischemia changes on ST-T in the Holter reports of patients in observation group were higher than those in control group (P<0.05 or P<0.01). The incidence of cardiac sudden death of patients in observation group was also higher than patients in control group (P<0.05).ConclusionClinical symptoms such as severs dyssomnia, anxiety agitation, emotion depressing are easily occurred in senile coronary heart disease patients with depression. Patients with depression have higher incidence of cardiac sudden death, having better relationship and society support are advantageous to prevent and reduce the depression in senile coronary heart disease patients.

OBJECTIVE: To study improvement effects of ethanol extract from Taxillus sutchuenensis on blood glucose level, liver and renal complications in type 2 diabetes mellitus (T2DM) model mice and its mechanism. METHODS: T2DM model was established by high-glucose and high-fat feed combined with intraperitoneal injection of streptozotocin. Totally 60 T2DM model mice were randomly divided into model control group (normal saline), positive control group [metformin, 150 mg/(kg·d)] and T. sutchuenensis ethanol extract high-dose, medium-dose and low-dose groups [30, 15, 7.5 g/(kg·d), by crude drug], with 12 mice in each group. Other 12 normal mice were included in blank control group (normal saline). After given drug solution or normal saline for consecutive 28 d, the serum levels of FBG, FINS, IL-2, IL-4, IL-12, IFN-γ, Scr, BUN, ALT and AST were detected; 24 h urine was collected to detect the Ucr levels. The insulin sensitivity index (ISI) and insulin resistance index (HOMA-IR) were calculated. HE staining was used to observe the pathological change of hepatocytes. The levels of Bcl-2 and Bax in liver tissue as well as the levels of TLR4 and NF-κB p65 in renal tissue were detected. RESULTS: Compared with blank control group, the serum levels of FBG, FINS, IL-4, ALT, AST, BUN, Scr and HOMA-IR value were increased significantly in model control group, while the levels of Ucr, IL-2, IL-12, IFN-γ and ISI value were decreased significantly (P<0.01). The hepatocytes showed obvious pathological changes. Bcl-2 level and Bcl-2/Bax of liver tissue were decreased significantly, while Bax level was increased significantly (P<0.01). The levels of TLR4 and NF-κB p65 in renal tissue were increased significantly (P<0.01). Compared with model control group, histopathological changes of liver were relieved significantly in T. sutchuenensis ethanol extract groups. Except that there was no significant difference in serum level of IFN-γ and level of NF-κB p65 in renal tissue in T. sutchuenensis ethanol extract low-dose group, other indexes were improved significantly (P<0.01 or P<0.05). CONCLUSIONS: T. sutchuenensis ethanol extract can improve high blood glucose, liver and renal complications, and protect liver and renal function in T2DM model mice. The mechanism may be associated with improving immunofunction, up-regulating anti-apoptosis factors, down-regulating the expression of apoptosis-promoting and inflammation- promoting factors so as to maintain the functional status of hepatocytes and reduce the degree of renal cell damage.

The correct differentiation of oligodendrocyte precursor cells (OPCs) is essential for the myelination and remyelination processes in the central nervous system. Determining the regulatory mechanism is fundamental to the treatment of demyelinating diseases. By analyzing the RNA sequencing data of different neural cells, we found that cyclin-dependent kinase 18 (CDK18) is exclusively expressed in oligodendrocytes. In vivo studies showed that the expression level of CDK18 gradually increased along with myelin formation during development and in the remyelination phase in a lysophosphatidylcholine-induced demyelination model, and was distinctively highly expressed in oligodendrocytes. In vitro overexpression and interference experiments revealed that CDK18 directly promotes the differentiation of OPCs, without affecting their proliferation or apoptosis. Mechanistically, CDK18 activated the RAS/mitogen-activated protein kinase kinase 1/extracellular signal-regulated kinase pathway, thus promoting OPC differentiation. The results of the present study suggest that CDK18 is a promising cell-type specific target to treat demyelinating disease.
