Objective To summarize our experience on laparoscopic appendectomy combined with high ligation of the vaginal process in children.Methods From January 2004 to May 2007,totally 326 patients with appendicitis underwent laparoscopic appendectomy in our hospital.During the operation,by inguinal exploration,83 cases of vaginal process deformity (17 bilateral and 69 unilateral lesions) were confirmed.High ligation of the vaginal process was performed on these patients.Results The operation was successfully done in all of the 83 cases,none of them showed postoperative complications.The cases were followed up for 6 to 12 months,during which only one patient had recurrent inguinal hernia.Three patients developed latent hernia but receined no treatment. Conclusions Laparoscopic appendectomy combined with high ligation of the vaginal process is an safe,effective,and low-cost procedure,leading to quick recovery and less pain for children with appendicitis complicated with vaginal process deformity.

Objective To investigate the role of interleukin-17 (IL-17) in glomerulosclerosis secondary to adriamycin-induced nephropathy in rats. Methods Male Sprague-Dawley rats were divided into normal control group and adriarnycin-induced nephropathy group(model group). Eight rats were sacrificed at 2nd week, 4th week, 8th week, 12th week respectively. Histopathological changes of renal tissue were observed under light microscope and glomerulosclerosis index was evaluated. The expression of IL-17 was measured by RT-PCR, ELISA and immunohistochemistry. The expression of IL-1β was detected by ELISA. Results Compared with control group, the expressions of IL-17 mRNA, IL-17 and IL-1β protein were higher in model group of the 8th week (P=0.041, P=0.000 and P=0.007 respectively), even they were further higher in model group of the 12th week than that in the control group (all P=0.000). In model group of the 12th week, the level of IL-17 protein had positive correlation with IL-1β and glomerulosclerosis index (P=0.037, P=0.021 respectively). Conclusion IL-17 expression is elevated and may contribute to glomerulosclerosis in adriamycin-induced nephropathy.

Objective To explore the characteristics and laws of burned children,and to find the coping strategies on preventing and reducing the incidence of pediatric burns.Methods The age distribution,burn causes, degree of burn,easy -happening months and on -site treatment of 978 children under 12 years old were retrospective-ly analyzed.Results 978 pediatric burns patients made up 55.4% of all burned patients among which there were 601 male patients and 377 female patients.Most of them were 1 -3 years old.The main reason of burn was hot liquid. Most of them were minor and moderate burned.The easy -happing months were from May to September.Only 11.0%of these children were correctly treated.Most burn children were from countryside.Conclusion The main reasons of children being burned are poor management of hot liquid,carelessness and the indifference of safety consciousness. The cases of burned children are regular.It is important to strengthen the publicity and education of precaution and the consciousness of safety protection of custodian.The publicity of knowledge about burning safety and correct on -site treatment are important for prevention and cure of burned children.

BACKGROUND:Regional myocardial diastolic dysfunction has been recognized as a sensitive and characteristic sign of myocardial ischemia and infarction,train rate imaging(SRI)is a novel ultrasonic technique with good spatial and high temporal resolution,nd it can be used to quantitatively analyze regional myocardial function.OBJECTIVE:To investigate the characteristics of the longitudinal diastolic strain rate(SR)in ischemic and infarct myocardium by SRI,n order to explore the clinical value of SRI in evaluating regional left ventricular diastolic dysfunction in patients with coronary artery disease.DESIGN:A case-control study.SETTING:Department of Cardiology.Second Affiliated Hospital of Sun Yat-Sen University.PARTICIPANTS:All the participants were selected from outpatients and/or inpatients of the Second Affiliated Hospital of Sun Yat-sen University between October 2005 and April 2006.Twenty-one patients with myocardial infarction(MI group)and 11 patients with angina pectoris(AP group)were enrolled in the study.Twenty age-matched healthy subjects served as controls.METHODS:After performing conventional echocardiographic examination,olor tissue Doppler images from apical four-,three- and two-chamber views (posterior septum and lateral wall,nterior septum and posterior wall,nterior and inferior wall)were recorded on magneto-optical disk.Then SR curves were derived from the stored images off-line using QLAB 4.2software.MAIN OUTCOME MEASURES:Ischemic segments in the AP group,nfarct segments in the MI group and normal segments in the control group were analyzed.The parameters measured included peak early diastolic SR (SRe)and peak late diastolic SR(SRa).RESULTS:Compared with the normal myocardium,oth SRe and SRa decreased significantly in the infarct and ischemic myocardium(all P＜0.05).No significant differences were observed with respect to SRe and SRa between the infarct and ischemic myocardium(both P＞0.05).CONCLUSION:SRI can be used to quantitatively analyze regional myocardial diastolic dysfunction in patients with coronary artery disease,ut its value is limited in differentiating infarct from ischemic myocardium.

Objective: To develop Attributional Style Questionnaire for Adolescents (ASQA) and explore the correlation between attributional style and mental health in adolescents. Method: ASQA was drawn up through referring to Peterson's method. 534 students were measured by ASQA, SSDA, SAS and MMOCI. Results: The goodness of fit indices of three-factor model in ASQA as follows: x2/df = 511.69/188, GFI = 0.91, AGFI = 0.89, NNFI = 0.91, CFI = 0.92, IFI = 0.92. Cronbach's α coefficient was 0.82. Spearman - Brown split - half reliability was 0.84. Stable and global variables entered the equations of depression, anxiety, obaession and compulsion in multiple linear regression analysis. Conclusion:ASQA had good reliability and construct validity. Adolescents were in low level of mental health when they attributed negative events to stable and global causes.

AIM: To study the effect of changing left ventricular afterload and isolated perfused rabbit heart on ventricular refractory period measured by subhthreshold conditioning train stimulation (St).METHODS:Ventricu- lar refractory pened strength- interval relation was measured by St method under the condition of changine left ven- tricular afterload and elimination action of nervous and body fluid.RESULTS: Reducing left ventricular afterload pro -longed ventricular refractory period measured by St method (P

Objective To summarize the achievement and experience in leprosy control in Jiangxi Province and provide scientific basis for formulation of leprosy strategies. Methods Based on the National Leprosy Recording and Reporting System, epidemiological data of leprosy in Jiangxi Province were analyzed using computer. Results Jiangxi Province was a leprosy medium endemic area with a higher distribution of leprosy in the south than the north. The prevalence, incidence and detection rates were highest in the 1959s or 1960s and had decreased annually since then. Average incidence rate for the recent 5 years (0.1604 per 100 000) and prevalence rate (0.049 per 10 000) in 1998 reached the criteria of basic elimination of leprosy at provincial level, however, still 15 counties or cities not reaching the criteria. Conclusion The comprehensive measures including early detection of cases, immediate treatment with multidrug therapy and effective health education are helpful and important for leprosy control.
