Objective Use high-frequency ultrasound to determine the frequency of visualization and image feature of the appendix in children with acute appendicitis (acute appendicitis, AA) and with acute infectious enteritis (acute infectious enteritis, AIE). Methods The ultrasonic features of 120 children with AA, 160 children with AIE, and 120 randomly selected asymptomatic children were analyzed retrospectively. And their visualization rate, outer appendiceal diameter, presence or absence of inflamed periphery appendiceal mesenterium, and location of the appendix were recorded. Results The visualization rates of the appendix were 96.7%, 80.6%, and 68.3% for AA groups, AIE groups, and the control, respectively(P<0.05). The outer appendiceal diameters for the 3 groups were (8.5±2.2)mm, (4.3±0.8)mm, and (3.5±0.7)mm. Difference among the 3 groups was statistically significant also. Periphery appendiceal inflamed mesenterium was detected in all AA cases, but in none of the AIE cases. Conclusion High ultrasound imaging sensitivity of puerile acute appendicitis provided relatively accurate comprehensive imaging basis for clinical early diagnosis and early treatment.

目的 调查广州市在校大学生AIDS相关知识及对HIV感染者态度现状,为学校更有效地开展大学生AIDS健康教育提供依据。方法 采用目的抽样方法,对广州市某高校 1200名在校大学生进行关于AIDS相关知识、态度的问卷调查。结果 不同年级、生源地,AIDS相关知识差异均有统计学意义(P值均＜0.01);多数学生对HIV感染者持积极态度,但仅5.73%的学生愿意与HIV感染者共餐;2.70%愿意与感染HIV的同学同住一个寝室。网络是大学生获取AIDS相关知识的最主要途径。结论 大学生AIDS相关知识知晓率水平较高,但缺乏系统性和全面性;多数学生对HIV感染者持积极态度,但是一旦与自我卷入较深,即表现出对HIV感染者的回避甚至歧视。高校应加强对大学生AIDS健康教育的系统性、全面性和深刻性,以消除对AIDS的心理恐惧,达到对HIV感染者的零歧视。

Objective To investigate the AIDS related knowledge of the Guangzhou undergraduates and the attitudes on HIV infection status, for the school to provide basis for AIDS health education and to carry out AIDS health education during college students more effectively. Methods 1200 college students in a university in Guangzhou were surveyed by a questionnaire on HIV/AIDS related knowledge and attitudes, using the way of purposive of sampling. Results There was statistical significant difference on the AIDS-related knowledge in the different grades and origin of students (P<0.01). The majority of students has a positive attitude to the HIV-infected, but only 5.73% of them wer willing to share a meal with HIV-infected persons, and 2.70% of them were willing to live with HIV-infected. The network is the most important way to access to HIV/AIDS related knowledge for college students. Conclusion The level awareness during college student on AIDS-related knowledge is high, but lack of systematic and comprehensive. The majority of students had a positive attitude towards the HIV-infetected, however once self-involved, they may avoid even discriminate the HIV-infected individuals. Therefore, the universities should strengthen AIDS health education of college students comprehensively and profoundly, in order to eliminate fear of AIDS, and reached zero discrimination HIV-infected persons in the future.

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.
