Objective To investigate the relationship between vascular remodeling patterns of atherosclerotic middle cerebral artery (MCA) stenosis and plaque enhancement.Methods From August 2015 to June 2016,patients with unilateral symptomatic atherosclerotic MCA stenosis underwent routine MRI and black blood magnetic resonance inaging examinations.The vessel area and lumen area of MCA at the site of atherosclerotic MCA stenosis were measured,and the degree of MCA stenosis and the remodeling index were calculated.Results A total of 33 patients were included.Eleven had obvious plaque enhancement,including 9 positive remodeling and 2 negative remodeling;22 did not have plaque enhancement,including 5 positive remodeling,5 no remodeling,and 12 negative remodeling.The obvious plaque enhancement group was mainly positive remodeling (81.8% vs.22.7%),and the no obvious enhancement group was mainly negative remodeling (54.5% vs.18.2%).The difference was statistically significant (P=0.018).Conclusion Plaque enhancement at the site of atherosclerotic MCA stenosis is mainly positive remodeling,which reflects plaque instability.

Objective To analyze the correlation between the resistance of Acinetobacter baumannii and the utilization of antimicrobial agents in the hospitalized patients of Beijng Chuiyangliu Hospital,and provide the basis for clinical rational use antimicrobial agents.Methods A retrospective analysis was conducted for the drug resistance rate and specimen source of the 2 194 strains of Acinetobacter baumannii from 2010 to 2014 in the hospital and DDDs/DUI of antimicrobial agents was analyzed by Pearson correlation.Results The resistance rate of Acinetobacter baumannii was positively correlated with the DDDs and DUI of imipenem/cilastatin(r=0.991,0.994,all P<0.01), and was positively correlated with the DDDs of cefepime(r=0.934,P=0.020).The resistance rate of Acinetobacter baumannii to amikacin was positively correlated with the DDDs of etimicin(r=0.931,P=0.022).The resistance rate of Acinetobacter baumannii was negatively correlated with the DUI of levofloxacin(r =-0.986,P =0.002). Conclusion The resistance rate of Acinetobacter baumannii was high and there was correlation between the drug resistance and the utilization of some antimicrobial agents.

Objective To analyze whether routine prophyrlactic antibiotic administration is necessary for the patients undergoing coronary stent implantation. Methods The clinical data of 156 patients from January 2010 to December 2010 (prophylactic antibiotic therapy),and 466 patients from January 2014 to December 2014(no-prophylactic antibiotic therapy), who underwent coronary stent implantation, were retrospectively analyzed. The prophylactic antibiotics and the infection rates in two groups were compared. Results The rate of infections related to coronary stent implantation in no-prophylactic antibiotic therapy group and prophylactic antibiotic therapy group, such as surgical site infection (0.2% vs 1.3%,P>0.05) and catheter-related infection(0.6% vs 1.9%,P>0.05), was not significant different(P>0.05). Similarly, the unrelated to coronary stent implantation was not significant different, too ( P > 0. 05). Conclusion Routine prophylactic antibiotic administration is unnecessary for the patients undergoing coronary stent implantation.

Objective To observe the effects of telmisartan and valsartan on insulin resistance in obese hypertensive patients. Methods Sixty-eight patients with essential hypertension and body mass index ( BMI) ≥25 kg · ( m2 ) -1 were randomly divided into the telmisartan group (33 cases) and valsartan group (35 cases). Blood pressure, fasting serum glucose, fasting insulin (Fins) and insulin resistance (HOMA-IR) were measured before and after 16 weeks treatment. Results Compared with basal levels, SBP and DBP were significantly decreased in both group ( P 0. 05);( 3. 0 ± 0. 7) vs. (3. 0 ± 0. 7) ( P > 0. 05), respectively]. Conclusion In obese hypertensive patients, telmisartan and valsartan exert similar antihypertensive effect, but telmisartan may have a benefit in insulin resistance in comparison to valsartan.

Objective To study the relationship between infection and hypokalemic paralysis and its clinical features.Methods A systemic analysis was made on the infection courses,clinical manifestations, serum levels of potassium and creatine phosphokinase,the results of electrophysiological and virological examinations in present 34 patients and 115 cases reported in literature with hypokalemic paralysis.Results There were differences in the clinical manifestations and denominations among the present and reported cases. No definite evidences for virus infections were found among patients who were characterized by acute flaccid paralysis accompanied with hypokalemia in the infection curses. The prognosis of the disorder was better after the patients were given potassium, and most of them didn't recur.Conclusion No enough evidences showed that this disorder was an independent disease.It should be named as "concomitant infectious hypokalemic paralysis" appropriately. It was probably a syndrome accompanied by infection on the base of hereditary susceptibility.
