Objective:To investigate the effects of electroacupuncture (EA) at Neiguan (PC 6) and Baihui (GV 20) by observing the changes of CCAAT/enhancer-binding protein(C/EBP) homologous protein (CHOP) and caspase-12 gene expressions in rats after cerebral ischemia-reperfusion injury (IRI), and explore whether the apoptosis pathway of endoplasmic reticulum stress (ERS) is involved in the protective mechanisms of EA.
Methods:Sixty rats were randomly assigned to five groups (12 in each group): a normal control group (group A), a sham-operation group (group B), an operation group (group C), an Edaravone group (group D) and an EA group (group E). The cerebral IRI rat model was induced by middle cerebral artery occlusion (MCAO) using intraluminal monofilament. 2,3,5-triphenyl tetrazolium chloride (TTC) staining was adopted in the measurement of cerebral infarction volume. Real-time polymerase chain reaction (RT-PCR) was used to determine the mRNA expressions of CHOP and caspase-12.
Results: Compared with group A and group B, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group C, group D and group E were increased, with statistical significances (P<0.05 orP<0.01); compared with group C, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group D and group E were decreased significantly (P<0.05 orP<0.01); there were no significant differences between group D and group E in comparing the above items (P>0.05).
Conclusion:EA at Neiguan (PC 6) and Baihui (GV 20) can effectively suppress the volume of cerebral infarction. Furthermore, the underlying mechanism of EA at Neiguan (PC 6) and Baihui (GV 20) is possibly related to the down-regulation of CHOP and caspase-12 mRNA expressions, so as to decrease cell apoptosis.

Objective To investigate the distribution and antibiotic resistance of clinical isolates in People’s Hospital of Qingyang during 2014 to provide evidence for rational antimicrobial therapy.Methods Bacterial strains were isolated and identified by routine methods and tested by disk diffusion method and E-test for antimicrobial susceptibility. The data were analyzed according to CLSI breakpoints using WHONET 5.6 software.Results Of the 2 121 nonduplicate strains isolated from January through December 2014, 1 565 (73.8%) were gram-negative and 556 (26.2%) were gram-positive strains. The top ifve pathogens wereE. coli, K. pneumoniae, A. baumannii, S. aureusand P. aeruginosa. The prevalence of methicillin-resistantStaphylococcus aureus (MRSA) and methicillin-resistant coagulase negativeStaphylococcus (MRCNS) was 44.6% and 15.4%, respectively.E. coli was the most common gram-negative bacterial species, whileS. aureus was the most common gram-positive bacteria species. Gram-positive bacteria were still highly susceptible to vancomycin, and gram-negative bacteria (such as Enterobacteriaceae) were still highly susceptible to carbapenems.ConclusionsE. coli is the most prevalent pathogen isolated from inpatients in this hospital during 2014. The prevalence of ESBLs-producing strains is the highest inE. coli isolates. The pathogenic bacteria in this hospital showed increasing resistance to a variety of antibacterial agents. Surveillance of antibiotic resistance and effective control measures are necessary to control the growing antimicrobial resistance.

Objective To study the association of carotid atherosclerosis with high-sensitivity creative protein(hs-CRP),lipoprotein-a(Lp-a) and superoxide dismutase(SOD) in patients with chronic renal failure (CRF).Methods Seventy-one CRF patients were divided into Group A of 45 patients under maintenance hemodialysis and Group B of 26 patients without hemodialysis,and 20 healthy donor was Group C in this study.And 71 CRF patients were divided into carotid atherosclerosis group (43 cases) and non carotid atherpsclerosis group(28 cases) according to whether the carotid atherosclerosis plaque was detected out.Fortythree CRF patients presented carotid atherosclerosis including 17 patients with soft plaque,10 patients with hard plaque and the other 16 with mixed plaque.Color ultra-sound was used to measure the carotid intimal medial thickness(IMT) and define the type of plaque.Levels of hs-CRP,Lp (a) and SOD were detected and analyzed in this study.Results (1) Levels of hs-CRP,Lp-a,SOD and IMT were significantly different in group A ((7.39±2.25) ag/L,(428.43±102.25) mmol/L,(71.35±21.52) KU/L and (1.23±0.31) mm,respectively),group B((7.41±1.67) mg/L,(432.12±96.43) mmol/L,(68.14±15.25) KU/L and (1.18±0.26) mm,respectively),and group C ((2.11 ± 0.86) mg/L,(193.32 ± 62.31) mmol/L,(94.23 ± 21.13)KU/L and (0.61 ±0.22) mm,respectively),the differences were significant (F =2.998,2.783,2.032,2.802;P＜0.05).Plaque incidence was increased in group A(68.9％) and group B(69.2％) compared with group C (12.5％) with statistical significance (x2=17.863,17.989;P＜0.001).(2) Furthermore,for CRF patients,hsCRP and Lp-a were positively related to IMT in group A (r =O.436,0.279;P＜0.05) and group B (r =0.652,0322;P ＜ 0.05),SOD presenting negative relationship with IMT (r =-0.283,P ＜ 0.01 for group A,and r =-0.164,P＜0.05 for group B).(3) Level of hs-CRP and Lp-a in carotid atherosclerosis group were higher than those in non carotid atherosclerosis group((7.58±2.47) mg/L vs.(3.41±1.26) mg/L,(437.31±115.38) mmol/L vs.(256.24± 101.22) mmol/L),the differences were significant (t =2.917,2.583;P ＜0.05).Level of SOD in carotid atherosclerosis group was lower than that in non carotid atherosclerosis group ((68.43±13.36) KU/L vs.(76.22±17.12) KU/L),the difference was signifiant(t=2.156,P＜0.05).(4)Level of hs-CRP and SOD in patients with soft plaque and mixed plaque were statistically different from those in patients with hard plaque(F=4.210,2.056;P＜0.05).Conclusion The micro-inflammatory status,oxidative stress and disturbance of Lp-a metabolism are extensively existed in CRF patients and closely connect to each other.Therefore,they might correlate with the formation of plaques in carotidartery.
