Objective To analyze the antimicrobial resistance profile of clinical isolates in Shanghai Xinhua Hospital Chongming Branch affiliated to Shanghai Jiaotong University School of Medicine , a member of China Antimicrobial Resistance Surveillance System, during 2015, for the purpose to facilitate rational antimicrobial therapy. Methods Strain identification?and?susceptibility?testing?were?carried?out?for?the?clinical?isolates?using?MicroScan?WalkAway?96?Automated?Systems and Kirby-Bauer method. Results In 2015, a total of 1815 isolates were collected, including gram-negative bacteria (73.2 %) and gram-positive bacteria (26.8 %). The top three frequently isolated species were Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. ESBL-producing strains were found in 36.3 % of the Escherichia coli isolates, 12.6 % of the Klebsiella (K. pneumoniae and K. oxytoca) isolates, and 28.0 % of the Proteus mirabilis isolates. The prevalence of carbapenem-resistant strains was 0.69 % in Enterobacteriaceae isolates. The prevalence of methicillin-resistant strain was 29.1 % in S. aureus, and 61.4 % in coagulase-negative Staphylococcus isolates. No more than 15 % of the Enterobacteriaceae isolates and no more than 20 % of the P. aeruginosa and Acinetobacter isolates were resistant to carbapenems. No vancomycin-or linezolid-resistant strains were found in Enterococcus or Staphylococcus. Conclusions Antibiotic-resistant clinical isolates are a serious threat for clinical antimicrobial treatment. We should pay more attention to such urgent situation and rational use of antibiotics.

OBJECTIVE: To assess the diagnosis and therapeutic effects for fungal otitis externa by clinical symptoms, endoscopic findings, and fungus culture of the ear discharge. METHOD: Sixty outpatients diagnosed with otitis externa were enrolled in the study. All patients were treated with a thorough debridement of the ear and one antifungal medication regimens (compound resorcinol solution) in case of a positive fungus culture. One subgroup of patients treated with daub glycerol during 2 weeks of follow-up. RESULT: Positive cultures were found in 42 cases. The efficacy was observed in all patients even in those who received only ear endoscopy. CONCLUSION Fungal otitis externa could be easily diagnosed by ear endoscopy. A thorough debridement of the ear and utility of compound resorcinol solution is an easy and effective approach for treatment of fungal otitis externa.

ObjectiveTo evaluate the fourth-generation ultrasonic lithotripsy system for treating the urinary tract stones.Methods243 cases of urinary tract stones who received treatment of fourth-generation EMS ultrasonic lithotripsy system were analyzed retrospectively.ResultsImmediate phase I lithotrotrisy was performed successfully in 227 cases and the successful rate of phase I was 93.3％ (227/243).Delayed phase Ⅱ lithotripsy was performed for 16 patients.Complications happened in 2 cases,one case occurred hydropneumothorax during operation,required indwelling thoracic drainage tube processing,the other had severe bleeding which conservative treatment was ineffective,cured by the intervention of super-selective renal artery embolization.Conclusion Fourth generation of ultrasonic lithotripsy for treating stones on different anatomical locations of urinary system was safe,practical and efficient,worthy of clinical application.

BACKGROUND: Human leukocyte antigen (HLA)-B27 is closely connected to the occurrence of some rheumatic diseases such as ankylosing spondylitis and can be used as an important factor for evaluating the diagnosis of ankylosing spondylitis. Immunomagnetic separation and enzymelinked immunosorbent assay (IMS-ELISA) has been applied to the detection of HLA-B27.OBJECTIVE: To explore the accuracy, sensitivity and specificity of IMSELISA for detecting HLA-B27 and its value in the auxiliary diagnosis of ankylosing spondylitis.DESIGN: A clinical trial in comparison with the gold standard.SETTING: Departments of Rheumatology and Clinical Laboratory, Third Affiliated Hospital of Sun Yat-sen University.PARTICIPANTS: Eighty-six patients suffering from low back pain and/or arthritis who were treated for the first time in Department of Rheumatology from December 2002 to April 2003. Inclusion criteria: ① Presence of manifestations of low back pain and/or arthritis; ② Thorough documentation of clinical and other examinations; ③ Informed consent to HLA-B27 examination; ④ Treatment for the first time in the Third Affiliated Hospital of Sun Yet-sen University. Those with other serious diseases or with incomplete record of clinical and/or accessory examinations were excluded. The 86 patients included 56 male and 30 female patients aged from 12 to 65 years.METHODS: Blood sample was detected for HLA-B27 by both IMS-ELISA and microlymphocytotoxicity test, and the latter was selected as the gold standard. The coincidence rate of the results detected by the two methods as well as the sensitivity, specificity, positive and negative predictive values of IMS-ELISA were calculated.MAIN OUTCOME MEASURES: ① The coincidence rate of the results of the two methods. ② The sensitivity and specificity of IMS-ELISA for detecting HLA-B27.RESULTS: None of the patients was lost. For the 33 patients with ankylosing spondylitis, the positivity rate of IMS-ELISA (90.9％) was higher than that of microlymphocytotoxicity test (87.9％), but the difference was not statistically significant (P＞0.05). The total coincidence rate of the two methods was 93.0％ in all the 86 patients. The sensitivity, specificity, positive and negative predictive values of IMS-ELISA were 90.0％, 95.7％,94.7％ and 91.7％ respectively.CONCLUSION: Both IMS-ELISA and microlymphocytotoxicity test are capable of reliable examination of HLA-B27 with high sensitivity and specificity.

Objective To study the animal toxicity test on skin of the Chinese herbal drugs liquid paste (CHDLP).Methods Acute and multiple times skin stimulation test and skin allergy test were performed on healthy guinea pig by using CHDLP.Results The acute skin stimulation score and intensity score were all zero.Multiple skin stimulation score and pathological examination score were all zero.So were the skin allergy score and the sensiti- zation rate.Conclusion CHDLP is a weak sensitizer and arose no skin stimulation on guinea pig.It's safe when ex- ternal use.

Objective:To determine the effects of pentoxifylline-tocopherol-clodronate combination (PENTOCLO) protocol in the treatment of localized temporal bone osteoradionecrosis (TBORN).Methods:A retrospective analysis was conducted on the clinical data of 21 patients, who suffered localized TBORN (23 ears) and were treated with the PENTOCLO protocol in Sun Yat-sen Memorial Hospital, Sun Yat-sen University from November 2020 to April 2021. The curative effects of the PENTOCLO protocol were evaluated based on the changes in ear symptoms and the extent of exposed bone before and after treatment.Results:The PENTOCLO protocol was applied for (506 ± 48) d on average. As a result, 19 ears (82.6%) became free of earache and purulent ear discharge, and two ears (8.7%) showed alleviation of symptoms. Moreover, nine ears (39.1%) exhibited re-epithelialization in the ear canal, 11 ears (47.6%) showed a decrease in exposed ear canal bone, and the osteonecrosis of three ears (13.0%) was stable.Conclusions:PENTOCLO has encouraging treatment effects on TBORN, and thus can be used as an effective nonsurgical option for localized TBORN.
