Objective To investigate the infection rates of toxin-producing Clostridium difficile and Candida albicans in patients with antibiotic-associated diarrhea (AAD) in West China Hospital of Sichuan University, analyze their clinical characteristics and make a survey of the therapy. Methods Fecal specimens of AAD patients were collected in West China Hospital of Sichuan University from September 2014 to January 2015. Toxin-producing Clostridium difficile and Candida albicans were identified by polymerase chain reaction and then clinical data of cases was collected and analyzed. Results Twenty-eight patients with Clostridium difficile infection were detected from the 126 AAD patients, 20 patients (15.9%) in whom were infected with toxin-producing Clostridium difficile. Type A+B+, type A-B+, and type A+B- accounted for 35.7% (10/28), 35.7% (10/28) and 28.6% (8/28), respectively. Fifty-four patients (42.9%) with yeast infection were detected. The predominant isolate was Candida albicans, accounting for 20.6% (26/126), and the others were Candida glabrata (n=11), Candida tropical (n=10), Candida parapsilosis (n=3), Saccharomyces cerevisiae (n=2), Pichia pastoris (n=1), and Kodamaea ohmeri (n=1). Toxin-producing Clostridium difficile strains and Candida albicans strains were both isolated from 3 patients (2.4%). The main antibiotics used in AAD ppatients were penicillins, carbapenems, third generation cephalosporins, and fluoroquinolones. AAD patients were all with underlying diseases at different degrees. The main treatments were probiotics and montmorillonite powder. Conclusion The relatively high infection rates and complicated factors of AAD indicate that much more attention needs to be paid to the diagnosis and therapy of AAD by the clinical doctors.
目的：探讨毒蕈中毒所致中毒性肝炎的临床表现、治疗与预后关系。方法：对3例急性毒蕈中毒患者进行回顾性临床分析。结果：3例患者均出现中毒性肝炎，2例经治疗后好转，1例因多器官功能衰竭死亡。结论：中毒性肝炎如导致多脏器损害，预后差；及早洗胃，彻底清除毒物是救治关键；血浆置换治疗有一定疗效，肝移植是最有效的治疗手段。
目的:探讨激素及免疫抑制剂导致乙肝病毒再激活所致的肝损害的危害性及治疗效果，指导临床治疗。方法：总结本院近2年收治的7例慢性乙肝病毒感染者在使用激素及免疫抑制剂致肝炎再激活并加重患者的临床资料进行分析。结果：慢性乙肝病毒感染者因各种原因使用激素及免疫抑制剂所导致的慢性乙肝的复发加重，病情发展迅速，病死率高。结论：抗乙肝病毒治疗是预防肝病复发并恶化的关键，在激素或免疫抑制剂治疗前和治疗中都应使乙肝病毒降至尽可能低的水平。
目的：对鲍曼不动杆菌感染的临床特征和耐药性进行分析，为临床诊治提供参考。方法：对2005年1月～2006年6月我院临床分离的共107株鲍曼不动杆菌通过琼脂对倍稀释法进行MIC测定；同时对相应的临床病例进行回顾性分析。结果：107株鲍曼不动杆菌大多分离自痰液，主要来自于ICU病房；且91.59%的患者同时存在2种以上基础疾病。鲍曼不动杆菌对氨曲南耐药率最高，为89.72%，依次是头孢西丁(87.85%)，头孢哌酮(76.64%)、哌拉西林(69.16%)、头孢噻肟(65.42%)、环丙沙星(65.42%)、阿米卡星(56.07%)、头孢他定(5514%)等。结论：我院鲍曼不动杆菌耐药情况严重，治疗首选碳青霉烯类抗生素，其次可选用头孢吡肟、头孢哌酮/舒巴坦。
Clinical practice is very important in clinical pharmacology education. However, there are some deficiencies in this field in China. Clinical trial institutions in China are medical institutions that are qualified to undertake drug clinical trials. There are hardware and software for clinical pharmacology practice, and high-quality teaching personnel with medical, teaching, and scientific research backgrounds in the clinical trial institutions, which can be used as clinical pharmacology teaching practice bases. Therefore, this article discusses the practice of clinical pharmacology teaching reform using clinical trial institutions as a practical platform, and aims to put forward teaching reform ideas that combining students’ clinical pharmacology research practice on the basis of theoretical teaching.
【摘要】 目的 评价高效抗逆转录病毒疗法（highly active antiretroviral therapy，HAART）对艾滋病患者的疗效，并观察其耐药情况。 方法 2008年11月，对23例接受免费HAART治疗1~3年的艾滋病患者的HIV-RNA病毒载量、HIV-1耐药、CD4+T淋巴细胞绝对计数、常规生化检测结果进行分析。 结果 23例艾滋病患者在HAART治疗1~3年后有6例（26.1%）患者HIV-RNA载量在水平线以下，17例（73.9%）HIV-RNA载量未达到检测线以下。5例患者（21.7%）的HIV-1发生了耐药，服药依从性良好的患者仅9例（39.1%）。 结论 HAART对艾滋病患者的疗效较差、耐药率高、服药依从性差。【Abstract】 Objective To evaluate the efficacy of highly active antiretroviral therapy (HAART) in treating HIV, and observe the resistance of HAART in AIDS patients. Methods Twenty-three HIV patients receiving free HAART for one to three years were investigated. The plasma viral load, drug resistance to HIV-1, CD4+ T cell count were tested and routine laboratory examinations were performed in our study. Results After one to fhnee-year HAART treatment, HIV viral load of six patients (26.1%) declined to the undetectable level, while the viral load of 17 patients (73.9%) kept at a high level. Resistance to HIV-1 occurred in five cases (21.7%). Only nine patients (39.1%) had good treatment compliance. Conclusion HAART has a poor therapeutic effect on patients with HIV/AIDS with a high rate of drug resistance and poor treatment compliance.
Objective To explore the expression differences of procalcitonin (PCT) in different infection sites and bacterial strains, and to provide the evidence for early differential diagnosis of infectious diseases with PCT as a biomarker. Methods The patients with various kinds of infections diagnosed in West China Hospital of Sichuan University between January 2012 and June 2016 were retrospectively included. The expression differences of PCT in various infection sites and bacterial strains were analyzed. Results A total of 1 005 patients were include in this study, including 259 with systemic infection and 746 with local infection. The median PCT level in the systemic infection group was higher than that in the local infection group (8.57 vs. 0.10 ng/mL, P<0.05). In the 779 patients with pulmonary infection, the median PCT level of the patients with sepsis caused by pulmonary infection was higher than that of the ones without sepsis (4.61vs. 0.10 ng/mL, P<0.05), and the median PCT level of the patients with positive sputum culture was higher than that of the ones with negative sputum culture (0.28vs. 0.08 ng/mL, P<0.05). In the 48 patients with urinary tract infection, the median PCT level of the patients with sepsis caused by urinary tract infection was higher than that of the ones without sepsis (12.00vs. 0.42 ng/mL, P<0.05), and the median PCT level of the patients with complicated urinary tract infection was higher than that of the patients with simplex urinary tract infection (19.15vs. 5.02 ng/mL, P<0.05). In the 259 patients with systemic infection, the median PCT level of the patients with infective shock was higher than that of the ones without infective shock (40.26vs. 3.83 ng/mL, P<0.05); the mean PCT level of patients with infection of Gram-negative bacteria, Gram-positive bacteria and fungi was 13.66, 0.99, and 3.30 ng/mL with a significant difference (P<0.05). Conclusion The PCT level has unique advantages in identifying different sites of the infection, early diagnosing complicated urinary tract infection, and evaluating the severity of infection, which could provide evidence in early identification for sepsis caused by various kinds of infectious pathogens.
