Beijing University of Traditional Chinese Medicine, Shanghai University of Traditional Chinese Medi-cine, Guangzhou University of Traditional Chinese Medicine, Tianjin University of Traditional Chinese Medicine, Nanjing University of Traditional Chinese Medicine, and Chengdu University of Traditional Chinese Medicine served as the study object in this study.Their published patent data were recorded and analyzed in terms of the number and types of patent applications, the number of validated patents, and the distribution of patent technologies using the patent information service platform on China Intellectual Property Right Net in order to understand their scientific research level, innovative ability, and scientific research trends.Certain suggestions were put forward for the solu-tion of existing problems and for working out strategies for the protection of intellectual property right.

After the status quo of ESI-covered pharmacology, toxicology and clinical medicine in domestic universities of traditional Chinese medicine was described, the papers and highly-cited papers published by these universities, total citations, citations of each paper were ranked and compared.The related problems and development tendency of different subjects were analyzed with suggestions put forward for the construction of first class subjects in domestic colleges and universities of traditional Chinese medicine.

Objective To investigate the resistance mechanisms and epidemiology of Enterobacteriaceae isolated from clinical with reduced susceptibility to imipenem or meropenem.Methods 18 strains of Enterobacteriaceae with reduced carbapenem susceptibility were collected during January to August in 2010.The MICs of these strains were determined using automated microbial identification system.ESBLs,AmpC and KPC were tested using the agar dilution method.PCR amplification and DNA sequence were performed to analyze the KPC genes,PFGE was used to examine the molecular epidemiology.Results All 18 strains were detected ESBLs and AmpC,14 strains were detected KPC-2.3 strains with EDTA paper method positive may produce other metal carbapenem,in which 2 strains harbor KPC-2.PFGE types indicate that there were six genotypes among 15 strains of Klebsiella pneumoniae.Conclusion Plasmid-mediated KPC-2 was the main reason which makes Enterobacteriaceae reducing carbapenem susceptibility and causes short-term epidemic in hospital.Clinical strains harboring KPC-2 gene may carry multiple resistance genes meanwhile.

AIM: To investigate the immunologic mechanism of CXC chemokine ligand 10(CXCL10) and its receptor CXC chemokine receptor 3 (CXCR3 ) involved in the process of endometriosis (EM). METHODS: Serum samples were collected from 3 groups; EM patients without operation (n = 76) , EM patients with operation (n = 10) and the normal control persons (n =76). CXCL10 and CA12S concentrations were detected by means of ELISA and chemilumino-metry. Cell surface antigens on the activated PBMC - CD3 and CXCR3, as well as CXCR3 subgene - CXCR3A and CX-CR3B were tested by flow cytometry (FC) and RT - PCR when PBMC was separated from women with EM ( n = 10) and without EM (n = 10), and then activated. RESULTS: Serum CXCL10 concentrations between three groups were signifi-canly different (P < 0.05). Compared to normal control group, although the supernatant CXCL10 concentration and CD3~+ /CXCR3~+ PBMC number in EM group has no significant difference (P >0.05) , highly expressed CXCR3B in EM group rather than CXCR3A was observed. CONCLUSION: CXCL10 in women with EM is low, indicating that it plays a vital role in the process of EM and immune system of the women with EM is defected and impaired. The immunoreactivity of PBMC from both EM patients and normal person is same to activated signal, but the productions are different: PBMC in EM group mainly express CXCR3B but PBMC in normal person mainly express CXCR3A after activation, which may be one of the immune mechanisms that EM escapes from immunological lethal effect of the infected host.

Objective To retrospectively analyze the clinical distribution and changes in antimicrobial resistance profiles of Staphylococcus aureus (S. aureus). Methods We collected clinical specimens of S. aureus from The First Hospital of China Medical University. The Vitek-2 and BD Phoenix 100 were performed for bacterial identification and drug sensitivity tests,and WHONET 5.6 was used to analyze the data. Results From 2007 to 2016,there were 3 377 unrepeatable strains of S. aureus,including 1 705 that were methicillin resistant S. aureus (MRSA). The isolation rate of S. aureus was 9.4 ％ and of these,50.5 ％ were MRSA. There were 776 S. aureus specimens from outpatients or the emergency department,including 16.8 ％ MRSA,and 2 011 S. aureus from inpatient departments,including 60.2 ％ MRSA. The main sources of specimens were sputum (41.8 ％),pus (17.9 ％),and body secretions (17.5 ％). The average resistance rates of MRSA for erythromycin,ofloxacin,ciprofloxacin,gentamycin,and tetracycline were higher than 75.0 ％. The average resistance rate of methicillin sensitive S. aureus (MSSA) for erythromycin was up to 76.8 ％,and for tetracycline,gentamycin,ciprofloxacin,and ofloxacin,were less than 25.0 ％. In 10 years,the average resistance rates of MRSA and MSSA for 11 kinds of common antibiotics had no obvious change. Conclusion The constituent rate of MRSA was high in The First Hospital of China Medical University,especially from the areas that were not sterile,suggesting that clinicians should pay attention to the identification of infection and sources for MRSA,which were from such areas. Hospital infection control should be focused on at the same time,in order to reduce the incidence of MRSA.
