Chinese Journal of Medical Education Research 2003;0(03):-
Medical education has its own peculiarities, so does the management of medical students. To establish a management pattern which is appropriate to medical students' all-round development, needs to find out a management pattern appropriate to the medical department of comprehensive university, to summarize the present management pattern of medical students in different medicine colleges, and to put forward the principles and problems which ought to be followed and paid attention to during the reformation, on the principle of being based on students, setting up standard system and improving the quality of managers.

Medicine has the close relationship with human beings.The conception of human body in medical science is quite different from that in the other fields.Therefore,the aesthetic sense of medical students has its own characteristics.And the medical science itself also asks the medical students to have the superior aesthetic culture than any other students.Thus,they can perform perfectly in the medical work that needs to contact people directly,and become the qualified doctor to maintain the human's health and rehabilitate the human's aesthetics.

Objective To provide the applied anatomy of the posterior intercostal artery perforator flap and the clinical results of repairing the soft tissue defects with lateral perforator flap. Methods Six fresh adult cadavers were injected with a lead oxide-gelatin mixture for three-dimensional visualization reconstruction using a 64-slice spiral computed tomography scanner and specialized software (Materiaise's interactive medical image control system,MIMICS).The origin,course,diameter,and distribution of the the 6-10th posterior intercostal artery perforators in the thoroax region were observed and measured.Clinically,nine cases were treated with the lateral perforator flap supplied by 7-10th posterior intercostal artery transplantation for repairing wounds in upper limbs.The flap size was 9 cm × 7 cm-16 cm × 12 cm. Results The 6-10th posterior intercostal artery perforator (outer diameter 1.70 ± 0.14 mm) were from the artery in the chest region, which pierce in deep fascia near midaxillary line. The average pedicle length from the deep fascia was (87.56 ± 6.48) mm.All of 9 cases were repaired successfully,the clinical results were satisfactory.Conclusion The posterior intercostal artery perforator flap can be used to form many kinds of axial skin flaps,it is a good option for repairing soft-tissue defect.

OBJECTIVE:
To evaluate the expression of eosinophil major basic protein (MBP) in chronic rhinosinusitis (CRS) and discuss the role of MBP in the pathogenesis in CRS.
METHOD:
Thirty-eight nasal mucus obtained from CRS patients were used to detect the expression of MBP by Elisa assay. Thirty nasal mucus samples from health people were used as control.
RESULT:
The expression of MBP of nasal mucus obtained from CRS patients was obviously higher than that of nasal mucus obtained from control. There was significant statistical difference (P < 0.01).
CONCLUSION
MBP was involved in the formation of CRS.

To examine the association between dietary zinc intake and phalangeal osteoporosis.
Methods: The subjects of this study were members aged over 40 years or above of the general population who had undergone routine health examinations at Xiangya Hospital, Central South University in Changsha, Hunan, China, between October 2013 and December 2015. Dietary zinc intake was measured using the semi-quantitative food frequency questionnaire. Phalangeal osteoporosis was diagnosed according to the WHO criteria based on the assessment of bone mineral density. According to the quartile distribution, serum zinc concentrations were classified into categories: Q1≤15.40 mg/d, Q2 15.41-18.67 mg/d, Q3 18.68-22.76 mg/d, and Q4≥22.77 mg/d. The association between dietary zinc intake with phalangeal osteoporosis was evaluated by conducting multivariable adjusted logistic regression. The dose-response relationship between them was assessed by restricted cubic spline regression.
Results: A total of 6 267 subjects were included, 602 (9.6%) among them were suffered from phalangeal osteoporosis. The multivariable-adjusted models (i.e. Model 2 and 3) showed that, compared with the lowest quartile, the odds ratios (ORs) for phalangeal osteoporosis were lower in the second, third and fourth quartiles of dietary zinc intake (Model 2: P for trend = 0.045; Model 3: P for trend = 0.031) in the total population; the ORs for phalangeal osteoporosis were lower in the third and fourth quartiles of dietary zinc intake (Model 2 and 3: P for trend = 0.018) in the male population; and the ORs for phalangeal osteoporosis were lower in the second, third and fourth dietary zinc intake quartiles (Model 2: P for trend = 0.227; Model 3: P for trend = 0.217) in the female population. There also existed dose-response relationship between dietary zinc intake and the prevalence of phalangeal osteoporosis (P<0.001).
Conclusion: Dietary zinc intake is negatively associated with phalangeal osteoporosis in the total population and male subgroup, but not female subgroup.
