Research progress of acquired reactive perforating collagenosis / 中国医师杂志

Reactive perforating collagenosis is a rare skin disease characterized by the expulsion of denatured collagen fibers through the epidermis. The specific pathogenesis of the disease is not clear, and according to the etiology it can be divided into hereditary and acquired. Hereditary is relatively rare, usually seen in infants, and acquired is usually seen in adults, often associated with other systemic diseases, such as diabetes, chronic renal failure, cirrhosis, pulmonary fibrosis, tuberculosis, pulmonary aspergillosis, thyroid disease, scabies, hepatitis, acquired immunodeficiency syndrome (AIDS), malignant tumors and so on. There is no standard treatment for the disease.

Occupational health status about radiation workers from township hospitals in Gansu, China / 中华劳动卫生职业病杂志

Objective@#To investigate occupational health status about radiation workers from township hospitals in Gansu, China, and to explore the dose-effect relationship of exposure dose of radiation workers.@*Methods@#A total of 390 X-ray workers from township hospitals in Gansu Province and 450 X-ray workers from the county/district-level hospitals in the county/district where the township hospitals were located were divided into research group and control group. Their workload, radiation protection condition, and occupational health monitoring data were used for impact assessment and risk estimation.@*Results@#The annual workload of radiation workers from township hospitals was 845.33±361.622 people, and that of radiation workers from county/district-level hospitals was 1967.74±762.055 people; there was a significant difference in annual workload between the two groups of subjects (P<0.05) . Indices such as detection rate of lens opacity, detection rate of abnormal platelet count, red blood cell count, and hemoglobin count, micronucleated lymphocyte rate, and chromosome aberration rate were significantly different between the two groups (P<0.05) .@*Conclusion@#Radiation workers from township hospitals suffer from certain radiation damage.

Isolation, identification and antimicrobial resistance of Campylobacter jejuni isolates from poultry in Jiangsu Province / 中国人兽共患病学报

The aim of the research is to study the prevalence and antimicrobial resistance of Campylabocter jejuni isolated from poultry in Jiangsu Province.A total of 753 samples from poultry meat and cloacal swabs were investigated,after the pure culture and the polymerase chain reaction of the mapA gene,207 isolates were examined for antimicrobial resistance by using K-B method according to World Health Organization.Results showed that all isolates performed different degree of antimicrobial resistance except meropenem,gentamycin,kanamycin,florfenicol and fosfomycin,the resistance rates of 194 strains to trimethoprim,norfloxacin,ceftriaxone and tetracycline were 100％,84.02％,80.9％ and 79.4％ respectively,1 strain isolated from Xuzhou was resistant to 92.6 ％ antibiotics.The multi-drug resistance appeared and the advantage of drug-resistant spectrum was LIN/CTX/CRO/NOR/CIP/T/TE,the resistant type focused on 40％-60％.The research provided evidence for surveillance of the antimicrobial resistance of C.jejuni and highlighted the need to employ more prudent use of critically important antimicrobial.

Association of serum level of apolipoprotein M with disease activity in systemic lupus erythematosus / 中南大学学报(医学版)

OBJECTIVE@#To explore the association of serum level of apolipoprotein M with disease activity in systemic lupus erythematosus (SLE).@*METHODS@#A total of 65 patients with SLE, who came to Second Xiangya Hospital for treatment from April to November in 2013 (SLE group) and 120 age-and sex-matched controls (control group) were studied. The SLE group was further divided into three groups according to systemic lupus erythematosus disease activity index (SLEDAI): a mild activity group, a moderate activity group and a severe activity group (n=16, 16, 33, respectively). The control group was also divided into a disease control group (n=60) and a healthy control group (n=60). The serum levels of apo M were measured by enzyme-linked immunosorbent assay (ELISA). Other indicators including TC, TG, HDL, LDL, apo A1, apo B, and anti-dsDNA antibody were detected. The correlation between SLEDAI or anti-dsDNA antibody and apo M was assessed.@*RESULTS@#Compared with the healthy control group, the expression levels of apo M and HDL were decreased significantly (both P0.05). The serum concentration of apo M was significant negatively correlated with SLEDAI and anti-dsDNA antibody (r=-0.551, -0.562, both P<0.01).@*CONCLUSION@#Compared with the healthy control group, the serum levels of apo M in patients with SLE are significantly decreased. The apo M is closely correlated with disease activity of SLE and it might be used as an indicator to monitor the disease activity of SLE.
