Objective:To study the clinical effect of corticosteroids (C S) with small dosage in the recurrence control of pemphigus. Methods: 25 cases of pemphigus were diagnosed by clinical and pathological examinati on.They were treated with CS at 60-80 mg/d in acute stage for symptom control.Th en,the dosage of CS was decreased by 5 mg in each following 2 weeks untill it re ached 2.5 mg/2 d. The treatment of 2.5 mg/2 d was continued for 1 year and was a ssisted with tripterygium polyglycoside, compound thalidomide, compound cyclopho sphamide (compounded with total saponins of ginseng), dapsone, and/or some kidne y-supplementing herbs. The patients were followed-up for 9~16 years.Re sults:No recurrence was observed in 16 cases(64%).Recurrence was found i n 9 cases(36%),among them 7(28%) were with light symptom and 2(8%) severe. Sever e side-effect was not found in all cases. Conclusion:The recurr ence of pemphigus may be controlled without severe side-effect by long-term us e of small dosage of CS assisted with proper immuno-inhibitors, immuno-regulat ors and/or some kidney-supplementing herbs.

Objective To construct and implement theSTARnurse training model, and discuss its application effect and the problems that should be paid attention to, and to provide operational cases and practical basis for nursing clinical education. Methods Through literature review and expert consultation, the framework and content of STAR nurse training model were set up and implemented. The questionnaire survey and semi structured in-depth interviews were conducted among the nurses in the hospital to evaluate the effect of improving the nurses′self-directed learning ability. Results After the implementation of the project, the scores of the three dimensions of self-management, desire for study and self-control were (3.67±0.57), (4.05±0.54), (3.99±0.50) points, which were higher than (3.55±0.49), (3.71± 0.52), (3.53±0.42) points before implementation. The difference was statistically significant (P<0.05 or 0.01). The semi structured in-depth interviews showed that all the nurses believed that STAR nurse training model could promote independent learning and stimulate interest in learning. 14 nurses thought it was beneficial for the nurses to find the problems. Conclusions STAR nurse training model can create a favorable learning environment for nurses, and stimulate the learning motivation. It plays a positive role in improving nurses′ability of self-directed learning.

Medical microbiology is basic course of medicine.In order to improve teaching quality,we employ discussing-mode education in microbiology.This education style can not only enlighten and train poly-directional thought ability,capacity of bringing forth new ideas and pioneering spirit,but draw close the distance between students and modern life science,which make microbiological course become beginning of exploring microbiology.The employment of education style of discussing microbiology new advance is effective pathway of exploring most suitable high-quality person of talent training.

Objective To understand the distribution of the genotypes of ?-lactamases in Chryseobacterium/Flavobacterium spp.Methods Minimum inhibitory concentrations (MICs) of 43 Chryseobacterium meningosepticum strains,22 Chryseobacterium indologenes strains and 10 Chryseobacterium gleum strains against 15 antibiotics were determined by agar dilution method.3-D test and modified 3-D test were used to identify carbapenamase.2-mercaptopropionic acid inhibitory test was used to confirm metallo-?-lactamases (MBL).Genes of ?-lactamases were amplified with 6 pairs of primers special for Chryseobacterium/Flavobacterium spp.and the amplified genes were sequenced.Results MIC_(50) and MIC_(90) of quinolones were lower comparing to other antibiotics.MICs of C.gleum against 15 antibiotics were lower than other Chryseobacterium/Flavobacterium spp.Among 43 C.meningosepticum strains,26 strains (60.5%) produce MBL,but all strains (100%) produced extended-spectrum ?-lactamases (ESBLs);12 C.indologenes strains (68.8%) produced MBL;6 (60%) C.gleum strains had MBL.Genotypes of MBL in C.meningosepticum strains were Bla-B 1,2,3,5 and 11,and Bla-GOB 2,4,6 and 8,respectively.Only one genotype,namely CME-1,was identified for ESBL in C.meningosepticum.The genotype of MBL in 3 C.indolgenes strains was IND-1,and the 6 C.gleum strains contained CGB genotype.Meanwhile,there were 8 C.indolgenes strains and 3 C.gleum strains were confirmed to produce ?-lactamase,but their genotypes were unable to be detected using the current primers,implying that there were possible novel genotypes.Conclusions Investigation of genotypes distribution of ?-lactamase in Chryseobacterium/ Flavobacterium spp.can provide theoretical evidences and rational in the selection of antibiotics,control of noscomical infection and development of novel antibiotics.

BACKGROUND:None of the current treatment strategies has been focused on relieving or reversing the disk degeneration process after degenerative disc diseases. In recent years, more and more scientists try to treat degenerative disc diseases using stem cel therapy. OBJECTIVE:To explore the research status and prospects of stem cel therapy for degenerative disc diseases. METHODS: A computer-based online search of PubMed database between January 2004 and December 2014was performed to search related articles with the key words of “stem cel, intervertebral disk” in English. Literatures related to stem cel therapy for degenerative disc diseases were selected; in the same field, the articles published lately in authoritative journals were preferred. RESULTS AND CONCLUSION: A total of 342 articles were primarily selected, and 43 articles were involved in result analysis according to inclusion criteria. Stem cel therapy is a newly treatment for degenerative disc diseases. Cels appropriate for stem cel therapy include embryonic stem cels, induced pluripotent stem cels, mesenchymal stem cels, human umbilical cord mesenchymal stem cels and chondrocytes or nucleus pulposus cels. Although cel leakage, intervertebral disc infection and tumorigenesis are the main chalenges, stem cel therapy for degenerative disc diseases is promising in the future.

Objective To investigate the differences of clinical features,pulmonary function tests,chest imaging and prognosis between patients with idiopathic pulmonary fibrosis (IPF) combined with emphysema and without emphysema.Methods A total of 43 patients with IPF and with pulmonary fibrosis and emphysema (CPFE) were selected as observation group,and 40 patients with IPF and without emphysema were selected as control group.The clinical data of two groups of patients,including pulmonary function,partial pressure of oxygen,cellular components of bronchoalveolar lavage fluid (BALF),survival time were retrospectively analyzed and compared between two groups.Results The smoking index was (29 ± 17) pack years in observation group,much higher than that in control group (17 ± 15) pack years,the difference was statistically significant (P ＜ 0.05).The percentage of forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) was (70 ± 6)％ in observation group,significantly lower than that in control group (84 ± 9)％,the difference was statistically significant (P ＜ 0.05).The percentage of diffusion capacity of carbon monoxide (DLCO) in observation group was (43 ± 11)％,significantly lower than that in control group (55 ± 17)％,the difference was statistically significant (P ＜ 0.05).The percentage of lung volume in observation group was (78 ± 12)％,significantly higher than that in control group (63 ± 11)％,the difference was statistically significant (P ＜0.05).The vital capacity was expected to account for partial pressure had no significant difference in percentage and resting arterial oxygen value between two groups (P ＞ 0.05).The total number of BALF cells,macrophages,neutrophils,lymphoeytes and eosinophils ratio had no significant difference between two groups (P ＞ 0.05).Conclusion Smoking is an important risk factor of IPF with emphysema,emphysema does not affect the prognosis of patients with IPF.
