Objective: To analyze the distribution and drug resistance characteristics of clinical separation germ in a hospital from 2013 to 2015 to provide reference and basis for the prevention and control of nosocomial infection and rational use of antibiotics.Methods: The microbial susceptibility of isolated strains was detected using the conventional methods, and the drug sensitivity was analyzed by BioMerieux ATB 1.22.The drug sensitivity was determined according to CLSI 2014 criteria.Results: A total of 18 421 specimens were isolated during 2013 and 2015, and a total of 3 744 strains were isolated with the total positive rate of 20.32%.The separation and identification of pathogenic bacteria at the top 5 were Escherichia coli (967 strains, 44.34%), Bauman Acinetobacter (323 strains, 14.81%), Klebsiella pneumoniae (312 strains, 14.31%), Staphylococcus aureus (297 strains 13.62%) and Pseudomonas aeruginosa (282 strains, 12.92%).Besides the natural resistance of Klebsiella pneumoniae to amoxicillin, the resistance rate of Escherichia coli to piperacillin was over 75%, while the sensitivity rate of Klebsiella pneumoniae to piperacillin and tazobactam was more than 90%.The sensitivity of Acinetobacter baumannii and Pseudomonas aeruginosa to clinical antibiotics was basically below 40%, and the overall resistance level was higher than that of Bauman.MRSA was sensitive to nitrofurantoin, minocycline, quinupristin-Dafoe and leptin glycopeptide antibiotics (such as teicoplanin and vancomycin).Conclusion: The hospital should strengthen the monitoring of bacterial resistance and track the results in a timely manner so as to provide reference for the rational drug use in clinical practice.

HBeAg seroconversion is an important process during antiviral therapy for patients with HBeAg-positive chronic hepatitis B (CHB), while the first-line antiviral drugs, such as entecavir and tenofovir disoproxil fumarate, tend to have low HBeAg clearance rate and/or seroconversion rate, and at present, there is still a lack of effective radical treatment regimens. Latest studies have shown that fecal microbial transplantation (FMT) can induce HBeAg clearance in HBeAg-positive CHB patients receiving long-term antiviral therapy. This article reviews the research advances in the role of FMT in inducing HBeAg clearance in HBeAg-positive CHB patients and points out that FMT may become a new treatment regimen for HBeAg-positive CHB patients.

Objective: To observe the long-term efficacy and safety of autologous hematopoietic stem cell transplantation (AHSCT) for systemic sclerosis (SSc) patients. Methods: Between May 2007 and June 2009,4 patients with SSc were enrolled in the study. Peripheral blood stem cells were mobilized with cyclopho-sphamide (CTX) followed by granulocyte colony stimulating factor (G-CSF). Conditioning was performed with i.v. cyclophosphamide 50 mg·kg^-1·d^-1 for 4 days. The results of the modified Rodnan skin score (mRSS), thoracic high-resolution computer tomography and pulmonary function were collected after transplantation. Results: There was an improvement in mRSS, lung function and HRCT in the six months after AHSCT. Within six month to one year after transplantation, one patient had sustained and two patients recurred. After active treatments two patients were improved again. During the follow-up of 8.7 (4.1-9.8) years, three patients were stable and one patient died. Infection and hepatic function injury were the major complications. There was not transplant-related mortality. Conclusion AHSCT with CTX as a pre-conditioning regimen is safe and effective for SSc. The efficacy for patients with short course, rapid progress and edema is significant. However, long-term efficacy is poor, and long-term maintenance treatment is needed.
