Objective To study the health status of radiological workers who explore to long-term low-dose radiation.Methods A cross-sectional study had been investigated according to the National Ministry of Health monitoring standards of radiological workers. Results The white blood cell and platelet counts of radiological worker were less than the control group. There was a significant difference with the rate of chromosome abnormalities and the rate of micronucleus in the radiological workers(P<0.05). With the growth of length of service time, the micronucleus rate rose up. Conclusion We need to strengthen awareness of radiation protection, shorten the time of radiation exposure, increase equipment support level to protect the health of radiological workers.
目的 对从淡水养殖鱼类、青蛙样品以及腹泻病人大便样品分离的菌株作临床常用抗生素的耐药性分析,为相关疾病的治疗提供实验依据。方法 获取临床腹泻病人的新鲜大便标本和在水产品市场采集淡水鱼和青蛙样品取肠道内含物分别涂布选择性培养基,选取疑似菌落进行生化鉴定和16S rRNA基因分子鉴定,确证为香港海鸥型菌的菌株采用纸片扩散法测定分离株对几类临床常见抗菌药物的敏感性。结果 本次检测的24株香港海鸥型菌分离株对八种常用的抗生素药物表现不同程度的耐药性。蛙源株对环丙沙星、阿米卡星、头孢他啶的耐药率高于鱼源株。其中分离的11株分离株(45.8%)对3个种类及以上抗生素表现耐药,为多重耐药株。结论 抗生素作为促生长剂和动物疾病防治被广泛加于动物饲料中,可能导致食源性细菌耐药性增加。人们有可能通过摄入含有香港海鸥型多重耐药株污染的食物而获得抗生素耐药性的潜在危险。

Objective To investigate the molecular characteristic of Community-acquired Methicillin-resistant Staphylococcus aureus(CA-MRSA) isolates from pediatric patients in Guangzhou. Methods 65 non-duplicate strains of Community-acquired Methicillin-susceptible Staphylococcus aureus(CA-MSSA) isolated from our hospital in 2009-2014 were investigated. Panton-valentine leukocidin(PVL) gene was detected by polymerase chain reaction(PCR). The sequence type (ST) of each strain was determined by muhilocus sequence typing (MLST). The genotypes of staphylococcal cassette chromosome mec(SCCmec) of the CA-MRSA isolates were confirmed by multiplex PCR. Results Among 65 isolates of CA-MRSA, the positive rate of PVL genes was 47.69%(31／65). The most common MLST type was ST59 (n=22, 33.84%), followed by ST88 (n=15, 23.07%). Three SCCmec types were found. The most common type was SCCmecIV (49.23%, 32/65), followed by SCCmecⅡ (32.30%, 21/65) and SCCmecV (8.46%, 12/65). Conclusion The PVL gene-positive rate of CA-MRSA isolates in our hospitals is at a relatively high level. SCCmec type IV and SCCmec type V could spread among hospitals and cause a small scale epidemic. Their phenotypes have a variety of ST types.

Objective To inverstigate the types and characteristics of allergen in children in different age with allergic diseases. Methods The food and inhalant allergen-specifi IgE(SIgE) were detected by the domestic specific IgE Screening ELISA kit in 174 children with allergic diseases,and were compared among children aged ≤3 and ＞3 years. Results 72.99%(127/174) of children with allergic diseases were positive for SIgE,the common allergen were dermatophagoides pteronyssinus/dermatophagoides farina and dust. In the group of ≤3 years old,the positives rate of food allergens was 33.93%(19/56),and the positives rate of aeroallergens was 44.65%(25/56).In the group of >3 years old, the positives rate of food allergens was 41.53%(49/118), the positives rate of aeroallergens was 61.02%(72/118).96 of 127(75.59%) positive cases yielded positive result to more than 2 allergens.69 patients's SIgE levels greater were ≥ 3,the mixed allergic rate and highly allergic rate of the children aged ＞3 years were higher than the children aged ≤3 years. Conclusion The children with allergic diseases in Guangzhou area were allergic mainly to inhalant allergens,especially to dermatophagoides pteronyssinus/dermatophagoides farina and dust.Aeroallergens are becoming the allergens as children grow with ages, and probability of mixture allergy is increasing.

Objective To analyze the influence of respiratory rehabilitation treatment on BODE coring system of patients with chronic obstructive pulmonary disease (COPD) in stable phase in rural areas. Methods 60 patients with COPD in stable phase admitted into the hospital were selected as the research object and were randomly divided into control group and observation group with 30 cases in each. The control group received conventional treatment while the observation group received respiratory rehabilitation treatment. The changes of BOBE coring system in the two groups before and after the treatment were compared. Results After the treatment, BMI, FEV1% MMRC classification and 6MWD of the observation group were (22.4±1.1) kg/m2, (68.6±3.6)%, (1.3±0.2) and (256.3±36.3) m respectively. The BODE index score decreased to (3.4±1.0), ADL (78.2±6.4), and QOL (67.8 + 2.6).compared with those of the control group, the difference was statistically significant (P< 0.05). And the decline level of inflammatory factors in the observation group was significantly higher than that of the control group (P<0.05). Conclusion In the clinical treatment of patients with COPD in stable phase in rural areas, respiratory rehabilitation treatment were adopted, the improvement of BOBE coring system indexes is significant. It is worthy to be popularized.
