Communicable diseases are the major threats to the health and security of all the people living in Liberia, including UN peacekeepers from China. The most prevalent communicable diseases in Liberia include malaria, HIV/AIDS, acute respiratory infection, sexual transmitted disease, schistosomiasis, onchocerciasis, tuberculosis, cholera, pertussis, hepatitis, meningococcal disease, typhoid fever, Lassa fever and yellow fever. An insight into the profiles and epidemiology of the above epidemics in Liberia would greatly help peacekeepers with disease diagnosis and epidemic prevention. According to the profiles of epidemics in Liberia and the authors' experience in epidemic prevention in Liberia, the authors recommend that peacekeepers strengthen their epidemic prevention as follows. Firstly, a combined vector control strategy is suggested for the prevention and control of vector-borne diseases. Secondly, water safety should be highlighted by water disinfection and regular water quality testing. Thirdly, vaccines, diagnostic reagents and medications should be accordingly outfitted. Then, the awareness of epidemic prevention and individual hygiene should be improved by education and strict management. Finally, the daily life management for peacekeepers is also very important. The epidemic overviews and strategies for epidemic prevention described in this paper are also useful for all the other peacekeepers deployed in Africa.

Objective To explore the changes of pathogens and antibiotic susceptibility in a respiratory ward.Methods All pathogens isolated from patients in a respiratory ward from 2001 to 2005 and the drug susceptibility results were retrospectively analyzed.For patients with more than 1 isolates of the same species, only the first strain of pathogen was included for analysis. The isolation and identification procedure was based on guidelines for national clinical laboratories.The susceptibility test was performed by disk diffusion method.WHONET 5.3 software was used for statistical analysis.Results A total of 876 strains were analyzed.The majority was gram negative bacteria.MRSA prevalence was 72.4% and showed a trend of increase.No vancomycin resistant Staphylococcus aureus or Enterococcus was detected.Streptococcus pneumoniae was highly resistant to macrolides.The non-sensitivity rate to penicillin was 25.5%-66.7% over years.The resistance rate to levofloxacin was 22.2%-27.3%.Enterobacter and Acinetobacter baumannii showed stable susceptibility to imipenem.ESBLs-producing Esche- richia coli and Klebsiella pneumoniae accounted for 33.3%-38.9% and 14.3%-19.2% respectively.P.aeruginosa strains were relatively susceptible to ceftazidime, amikaein, cefoperazone-sulbactam, imipenem, piperacillin-tazobactam and cefepime. The sensitivity rate was 87%, 82.6%, 78.3%, 73.9%, 73.9% and 71.4% respectively in 2005.Conclusions The changes of pathogens and antibiotic resistance in the respiratory ward were consistent with the surveillance data in this country, which were influenced by underlying diseases, severity of illness and antibiotic use.Our data are useful for the guidance of rational use of antibiotics.

Forty type 2 diabetic patients with diabetic peripheral neuropathy (DPN) were assigned to two groups and treated respectively with?-lipoic acid or mecobalamin for 2 weeks.The results suggested that?-lipoic acid could accelerate the nerve conduction velocity and decrease the plasma level of endothelin and C reactive protein as well as microalbuminceria with a effect similar to mecobalamin therapy on DPN.

Objective To find out the iodine nutritional status of children in Xiamen island, and to provide the scientific basis for iodine supplimentation. Methods On March 2010, thyroids of all children aged 6to 12, from primary school on the Xiaodeng island of Xiamen were examined by palpation, urinary iodine, iodine content of salt athome and IQ level were tested, and were collected 20 households, iodine content of drinking water was tested randomly. Results IQ testing and thyroid palpation were carried out among a total of 156 children, the goiter rate of children was 1.28% (2/156), the mean IQ was 110; 154 urine samples were taken, the median urinary iodine was 219.1 μg/L; a total of 153 salt samples were tested, and the qualified rate of iodized salt was 87.58%(134/153), and the mean iodine content in the tap water was 4.52 μg/L Conclusions Iodine nutritional status of the island residents is better, and there are no such problems as excessive iodine.

Enhancing medical students' humane quality education is an urgent requirement for modem medical mode transformation for medical education.The pharmacology teachers of Chongqing Medical University follow the modem education concepts and fully search the human spirit materials hidden in pharmacology,then actively explore how to integrate the humanity spirit education into the pharmacology teaching to achieve the changes of from exam-oriented education to quality education.

Objective To study adrenomedullin (AM) mRNA and protein expression level in myocardium of autoimmune myocarditis animal models induced by immunization of mice with lactobacillus casei cell wall element(LCWE). Methods Forty-five Balb/c male mice were randomly divided into experimental group (n = 30) and control group (n = 15), which were intraperitoneally injected with LCWE and phosphate buffered solution(PBS) at day 0,3,5 and 10,respectively. Sera and myocardium samples were gained 14,21 and 28 days after the first immunization. AM expression levels were determined by semiquantitative reverse transcriptase-polymerase chain reaction(RT- PCR) and immunchistochemistry,and mycardial histopathological lesions were observed. The anti- myosin antibodies in different stages were examined by an ELISA. Results There were myocardial necrosis or inflammatory infiltration in the experimental group, but myocardial lesions were not found in the control group. Anti - myosin antibodies were detected in sera of experimental mice,but not in control group. Immunchistochemistry findings demonstrated that AM expression level was higher in the experimental group than in the control group( P
