Objective To study children′s social adaptive capability and their relative factors.Methods Five hundred and twenty-seven children in 4 different kindergartens were surveyed by using the social adaptive capability-measuring list from infant to junior school student which revised by ZUO Qi-hua and questionnaire of family situation which compiled by TAO Gong-min and Zhu Xiao-qin.Results Twenty-five point three percent of the surveyed children′s social adaptive capabilities were higher than normal level.Sixty-eight point nine percent of them were at normal level.Four point seven percent of them were at edge level.The rest were at a slightly lower level.The influencing factors included the educational level of parents,the educational manner of the parents and their marriage relationship.Conclusions It is necessary to do some investigation to find problem eariler on children′s social adaptive capability.Suitable educational methods and good family environment are important to improve children′s social adaptive capability.

On the basis of the investigation of the pathogenesis of cervical spondylotic radiculopathy, this paper studies the mechanisms of spinal micro-adjustment manipulations in recovering and improving cervical dynamic and stationary balance from the perspective of biomechanics.

Objective To report a case of subcutaneous phaeohyphomycosis caused by Curvularia clavata in China. Methods The skin specimen was collected, and examined by KOH preparation, fungus culture and histopathology. Results A 17-year-old male farmer had dull red, warty and well-defined plaques with some ulceration on his face and his left upper arm for nine years and a history of trauma of his face before the appearance of the lesions. General examination did not reveal abnormal findings except the skin lesions. KOH direct examination showed septate hyphae with irregular branches. On the culture medium the colonies were black in color. Under microscope the conidia were borne singly or in groups at the tip or at the sides of the conidiophores, they were light brown to brown, smooth, straight or slightly curved and clavate, measuring 15 ~ 30 ?m long and 6 ~ 12 ?m thick, with 3 ~ 4 septates. Histopathology showed a granulomatous response. PAS staining showed irregularly swollen or toruloid conidia with branched hyphae. The isolated strain was identified as Curvularia clavata Jain. Conclusion It is the first case report of subcutaneous phaeohyphomycosis caused by Curvularia clavata in China.

The computerized imitating system constructed by the Second Affiliated Hospital of Guangzhou Medical University contains four blocks:administration of student infomation,administration of question bank,on-line tests and administration of score inquiry.It's designed to imitate typical pediatric cases,so that the medical students may put themselves into the practical clinical scenario and solve the challenges step by step in one-direction procedure.Teaching with computerized clinical scenario imitating patients can improve students' test resuhs and activate students' learning enthusiasm significantly.It not only helps to solve the contradiction between increasing number of medical students and clinical typical teaching case shortage but also improves the clinical thinking ability of the medical students.This system can also be used as a test bank for pediatric technical skills examination.

Arachidonic acid is an essential fatty acid in human nutrition and a biogenetic precursor of the biologically active prostaglandins and leukotrienes. ?~5 desaturase catalyzes the ?~5 dehydrogenation of di-homo-?-linolenic acid to form arachidonic acid in biosynthetic pathway of arachidonic acid. Using real time PCR technology,the transcriptional expression levels of gene encoding ?5 desaturase in three Mortierella alpina strains M10,M6 and M23,and in different growth phase of high arachidonic acid yielding strain M6,were determined. Results showed that there was a distinct corelationship between mRNA transcript level of ?~5 desaturase gene and biosynthesis of arachidonic acid. Results indicated that ?~5 desaturase plays an important role in arachidonic acid biosynthesis.

Objective To investigate the relapse risk assessment for patients with acute promyelocytic leukemia(APL)through testing PML-RAR? fusion gene by real-time quantitative polymerase chain reaction(RQ-PCR).Methods Relative copies of PML-RAR? fusion gene were measured in 25 patients with APL in phases of first diagnosis,complete remission(CR)and relapse.The minimal residual disease(MRD)situations were also monitored in 6 of the 25 patients.Results Different PML-RAR? fusion gene expression levels were observed in patient groups of different phases of the disease.(P

To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.
