ObjectiveTo evaluate rational use of antibiotics for hernioplasty in perioperative period by intervention-control study in order to provide a foundation for the clinical antibiotic use and management. MethodsThe data of the preventive use of antibiotics for hernia patients from January to October, 2010 in perioperative period were collected and compared. Interventions on patients from January to October, 2011 were carried out. ResultsIn the intervention group, the first three antibiotics used were changed from azlocillin, mezlocillin and aztreonam before intervention to cefazolin, clindamycin and azlocillin after intervention. Before intervention, antibiotics were first used after surgery for surgical prophylaxis, while after intervention, antibiotics were first used within 30 minutes before surgery or at the start of induction of anesthesia. The preventive medication time decreased from (3.50±2.07) days to (0.88±1.07) days (t'=14.601, P=0.000), the hospitalization days of post-surgery decreased from (5.17±1.90) days to (3.77±1.61) days (t'=7.313, P=0.000), the cost of antibiotics decreased from (342.39±415.50) yuan to (54.08±80.83) yuan (t'=8.831, P=0.000), the percentage of the cost of antibiotics in expenses for medicine declined from (47.53±25.51)% to (12.49±13.46)% (t'=15.776, P=0.000), and the percentage of the cost of antibiotics in hospitalization expenses declined from (6.59±5.49)% to (1.07±1.35)% (t'=12.662, P=0.000). The difference in inappropriate use of antibiotic drugs before and after prevention, such as choice of preventive drugs, preoperative medication occasion, course of postoperative medication and no indication of drug combination, had statistical significances (P<0.05). ConclusionThe intervention-control study shows that the rational use of antibiotics for hernioplasty in perioperative period can be improved, and the average hospitalization days and the cost of antibiotics can be reduced by intervention.
Peptidoglycan is an important component of bacterial cell wall, which plays an important role in maintaining the integrity of bacterial cell structure, stimulating immune response, and anti-infection. Peptidoglycan recycling is an indispensable process for bacterial cell growth and reproduction. In recent years, it has been reported that the peptidoglycan recycling is closely related to the occurrence and development of bacterial resistance, especially with the antibacterial activity of β-lactam antibiotics. In this paper, the relationship between peptidoglycan recycling and resistance is described by combining relevant reports and taking Mycobacterium tuberculosis and Pseudomonas aeruginosa as examples, so as to promote the understanding of bacterial resistance mechanisms and provide potential targets for the development of new antimicrobial drugs.

Methods A total of 763 patients who discharged from our hospital between January 2008 and October 2009 were sampled randomly for statistical analysis regarding the utilization. Results Of the 763 cases reviewed, all cases (100%) received antibiotics. In terms of the application of antibiotics, penicillins were predominantly used in 518 patients (48.05%), followed by cephalosporins in 336 patients (31.17%) and other antibiotics such as lincomycins nitroimidazoles and macrolides in 224 patients (20.78%). 574 patients (75.00%) received one antibiotic, 147 (19.00%) received two antibiotics and 42(6.00%) received at least three antibiotics concomitantly. Only 99 patients (12.98%) received etiological test and 39 patients (5.11%) received susceptibility test during antibiotic ues, most of them are G+ staphylococcus infected. Conclusion The perioperative use of antibiotics in our hospital is somewhat unreasonable, thus monitoring closely on which should be performed to promote their reasonable and normal use.

目的 了解国内妊娠期抗菌药物的应用现状。 方法 通过检索1994年－2012年国内医学文献，筛选出妊娠期间使用抗菌药物的原始病例报道，对收集的病例按照用药原因、抗菌药物品种、妊娠安全性分级进行统计分析。其中妊娠安全性分级是根据美国药物和食品管理局（FDA）颁布的药物危害等级标准，分为A、B、C、D、X级。 结果 妊娠期使用抗菌药物的常见原因为泌尿系统感染，选用的抗菌药物以头孢菌素和青霉素类为主（B类），但仍有部分病例选用C类、D类药物及超说明书用药。 结论 存在妊娠期抗菌药物不合理应用现象，妊娠合并感染性疾病需用抗菌药物时，医生应权衡抗菌药物对胎儿的可能危害及对母体的治疗作用，最大限度地避免用药对胎儿造成不良影响。
ObjectiveTo investigate the clinical settings, antibiotic susceptibilities, management and outcomes of streptococcal endophthalmitis. MethodsA retrospective observational case series study. Fifty six eyes of 56 patients diagnosed with streptococcal endophthalmitis in Eye & ENT Hospital, Fudan University from 2012 to 2022 were collected. The treatment followed the general principles of relevant guidelines, including pars plana vitrectomy (PPV), vitreous injection of antibiotics (IVI), vitreous injection of glucocorticoids and systemic application of antibiotics. The follow-up time was (11.9±17.0) months. Patients' clinical characteristics, pathogenic distribution and antibiotic susceptibilities, treatment and outcomes in their medical records were retrospectively collected and analyzed. ResultsAll 56 patients had monocular onset, including 39 (69.6%, 39/56) males and 17 (30.4%, 17/56) females, 26 (46.4%, 26/56) with left eyes involved and 30 (53.6%, 30/56) with right eyes involved. Their average age was (25.0±24.4) years. Ocular trauma was the leading cause of streptococcal endophthalmitis (73.2%, 41/56), followed by ophthalmic surgery (23.2%, 13/56) and endogenous infection (3.6%, 2/56). The streptococcal species included Streptococcus viridans (50.0%, 28/56), Streptococcus pneumoniae (18/56, 32.1%) and β-hemolytic Streptococcus (17.9%, 10/56). The susceptibility rates of Streptococcus to penicillin, cefatriaxone, vancomycin and levofloxacin were 66.0%, 57.1%, 94.1% and 92.4%, respectively. Patients received PPV+IVI and IVI as initial treatment were 49 eyes (87.5%, 49/56) and 7 eyes (12.5%, 7/56), respectively. Vitreous injection of glucocorticoids were performed in 17 eyes (30.4%, 17/56); and systemic antibiotics were applied in 52 cases (92.9%, 52/56). At the final follow-up, 47 eyes were recorded with visual acuity. Twenty (35.7%, 20/56) had best corrected visual acuity (BCVA)≥0.05 and 27 (48.2%, 27/56) had BCVA ＜0.05, of which 1 (1.8%, 1/56) had an eyeball enucleation. The etiology of endophthalmitis, streptococcal species, initial treatment with PPV, vitreous injection of glucocorticoids, and systemic antibiotics did not significantly affect patients' visual outcomes (P＞0.05). Timely visit to the hospital after the onset of symptoms (≤3 days) was significantly associated with achieving a final BCVA above 0.05 (P=0.025). ConclusionsOcular trauma was the primary cause of streptococcal endophthalmitis. Streptococcus viridans is the most common pathogenic bacterium. Streptococci had high susceptibility to vancomycin, but patients' visual outcomes were poor.
Antimicrobial stewardship (AMS) is an important means to control bacterial resistance. The unique situation of intensive care unit (ICU) poses a challenge to AMS. This article reviews the literature on AMS in the ICU at home and abroad in recent years, and summarizes the related measures of AMS. Effective AMS measures in the ICU include setting up a multidisciplinary AMS team, using rapid microbial diagnosis technology to shorten the time of diagnosis, using non-culture methods to assess the necessity of antimicrobial therapy for patients with suspected sepsis, and evaluating the effectiveness of antimicrobial therapy as early as possible and optimizing it. These initiatives aim to increase the rational use of antimicrobials in ICU, reduce the risk of multidrug-resistant infections, and improve patients’ condition.
ObjectiveTo study the clinical distribution and the change of drug resistance of Acinetobacter baumannii from different inpatient specimens sources during 2008 to 2012, and to provide guidance for rational use of antibiotics. MethodsThe identification of Acinetobacter baumannii was conducted by VITEK-2 based on clinical and laboratory standards institute (CLSI) guideline between January 2008 and December 2012. The susceptibility of antibiotics was determined by K-B test, and data analysis was conducted by Excel and SAS. ResultsA total of 3 139 stains of Acinetobacter baumannii were isolated from 2013 patients during this period. The Acinetobacter baumannii was mainly obtained from the Burn ward, Intensive Care Unit ward and Thoracic ward. Sputum was the most specimens of Acinetobacter baumannii, accounting for 48.4%. The drug resistance rates of Acinetobacter baumannii to most of the antimicrobial agents were more than 55%. Compound antibacterial is more effective than the single drug ingredient. Compared with other antimicrobial agents, β-lactams/β-lactamase inhibitor compound and carbapenems antimicrobial agents were more sensitive. ConclusionThe drug resistance of Acinetobacter baumannii is serious and has differences among hospitals. Clinicians should monitor the drug resistance of Acinetobacter baumannii timely and choose proper antibiotics according to the results of drug sensitivity.
