Objective To study the drug resistance of multiple‐drug‐resistant Acinetobacter baumannii(MDR‐Ab) and its rela‐tive carbapenemases genes ,in order to provide references for rational use of antibacterial agents .Methods A total of 98 strains of Acinetobacter baumannii(Ab) were identified by using the MicroScan WalkAway96 automated microbial identification susceptibility testing system ,and the resistance genes ,including OXA‐23 ,OXA‐24 ,IMP ,VIM ,TEM and SHV ,were detected by using the poly‐merase chain reaction .DNA sequences of positive amplification products of the resistance gene were analysed .Results The drug re‐sistance rates of 98 strains of MDR‐Ab to penicillin class and cephalosporin class both were 100 .0% ,to imipenem and meropenem were 55 .1% and 54 .1% respectively ,to gentamicin ,amikacin and tobramycin were 100 .0% ,100 .0% and 87 .8% respectively ,to ciprofloxacin ,levofloxacin and gatifloxacin were 89 .8% ,91 .8% and 77 .6% respectively ,to sulfamethoxazole and rifampicin were 91 .8% and 100 .0% respectively ,to polymyxin B and polymyxin were 14 .3% and 11 .2% respectively ,to tetracycline ,minocycline and tigecycline were 100 .0% ,6 .1% and 4 .1% respectively .The results of resistance genes detection in 98 strains of MDR‐Ab showed that 70 strains carried TEM and OXA‐23 gene ,53 strains carried VIM gene ,41 strains carried IMP gene ,while OXA‐24 and SHV genes were not detected .DNA sequence analysis showed that the homology of OXA‐23 ,TEM ,IMP and VIM genes were 98% ,98% ,99% and 99% .Conclusion The condition of antibacterial resistance of MDR‐Ab in this area is very serious ,and TEM and OXA‐23 are the main drug resistance genes .Carrying multiple resistance genes is an important cause of MDR‐Ab resistance . The treatment of patients with Ab infection should be based on the results of drug sensitivity test for rational use of antibacterial a‐gents .

Objective The sirolimus-eluting stent (SES) has dramatically reduced the rate ofrestenosis in comparison to that with the bare-metal stent (BMS).This study aimed to evaluate the short-term efficacy and safety of Firebird stent implantation for patients with coronary heart disease (CHD). Methods From Apri12006 through July 2007, 155 patients (mean age 58.93～10.27 years) with CHD were implanted with Firebird stent or Cypher select stent at Daxing Hospital. Patients were followed up for one year. All-cause mortality, major adverse cardiac events (MACE, including cardiac death, myocardial infarction, recurrence of angina pectoris, heart failure, revascularization, and adverse arrhythmia) and stent thrombosis were compared between the 2 groups. Results Of the 155 consecutive patients, 147 patients were revascularized completely. Of these patients, 48 (with 59 lesions) were treated with Firebird stent, 59 patients (with 75 lesions) with Cypher select stent. The demographic characteristics were similar in the 2 groups. All the angiographic and procedural results were not significantly different between the 2 groups. All-cause mortality, myocardial infarction, recurrence of angina pectoris, MACE and stent thrombosis were almost identical between the 2 groups before discharge, at 6 months and at one year .Conclusion The short-term efficacy and safety of Firebird stent are similar to that of the cypher select stent for the treatment of patients with CHD.

Mitochondrial fission regulator 2 (MTFR2) is associated with mitochondrial fission, while few studies have assessed the associations between MTFR2 expression and clinical characteristics or prognosis of esophageal squamous cell carcinoma (ESCC). In this study, we compared the expression of MTFR2 in 6 ESCC tumors and relative normal tissues by immunohistochemistry (IHC). To assess the effect of MTFR2 expression on clinicopathologic characteristics and survival, 115 paraffin embedded ESCC tissue samples were assessed by IHC staining. Furthermore, the association between clinicopathological properties and MTFR2 expression in patients with ESCC was examined. The survival analysis was performed using the Cox regression models. We found that MTFR2 expression was significantly increased in ESCC tumors compared with normal esophageal epithelial cells. IHC analysis of 115 paraffin embedded ESCC tumor specimens of the patients showed that the expression of MTFR2 was significantly associated with clinical stage (P < 0.001), tumor classification (P < 0.001), histological grade (P < 0.001), and other clinicopathological characteristics. Both univariate and multivariate analyses showed that MTFR2 expression was inversely correlated with the survival of ESCC patients. In conclusion, the expression of MTFR2 is significantly associated with clinicopathologic characteristics and prognosis of ESCC. Thus, MTFR2 expression could serve as a potentially important prognostic biomarker and clinical target for patients with ESCC.

Paraneoplastic neurological syndromes (PNS) are a rare group of immune-mediated disorders that affect the central and peripheral neuromuscular system in association with cancer.If the limbal lobe system of the brain is involved,it will show paraneoplastic limbal encephalitis(PLE).The discern of patients with PNS is challenging since tumors causing paraneoplastic neurologic disorders are often asymptomatic and sometimes occult.We report a case of PLE with double positive anti-Hu and Yo antibodies,and further analyze and discuss it in conmbination with relevant literature to improve the understanding of the disease.

Objective:To evaluate the clinical efficacy of microneedle radiofrequency in the treatment of moderate acne vulgaris.Methods:From August 2018 to August 2020, 393 patients (192 males and 201 females, aged 15-38 years) with moderate acne were enrolled in the Department of Dermatology, the First Affiliated Hospital of Shantou University Medical College and Shantou Chaonan Minsheng Hospital, including 201 patients in experimental group and 192 patients in control group. In the experimental group, microneedle radiofrequency therapy was used once every 2 weeks for 3 times in total. The control group adopted the fire needle, once every 2 weeks, a total of 3 times. The efficacy of both groups was evaluated at week 8.Results:A total of 378 patients were actually completed: 196 patients in the experimental group, and 182 patients in the control group. At the eighth week of follow-up, the total effective rate was 81.12% in the experimental group and 70.43% in the control group. The efficacy of the two groups was statistically different (χ 2=4.42, P<0.05). Conclusions:The efficacy of microneedle radiofrequency therapy in the treatment of moderate acne vulgaris is better than that of fire needle, with good tolerance, short recovery period, few adverse reactions and high compliance, which has clinical promotion value.
