ABSTRACT
By integration of traditional and Western medicine under particular historical conditions in China, some doctors of Western medicine are learning traditional Chinese medicine (TCM)and try to interconnect the two theories.To promote medical progress, they provide TCM services in clinic, such as acupuncture, herbal medicine, etc.But as we know that the laws are lacking for the doctors of Western medicine who want to carry out traditional Chinese medicine service.For the reason, the paper holds that at present there are three fundamental problems that should be solved.First of all, it must be clear that doctors should have qualifications and conditions to provide TCM service.Secondly, it must be clear that the doctors should have practicing scope to guarantee medical security and medical quality.Thirdly, it is imperative to strengthen TCM education and training for doctors.Now it is necessary to further strengthen the standardization of health supervision and law enforcement.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the feasibility of in vitro proliferation of rat Leydig cells by modifying the cell culture system.</p><p><b>METHODS</b>Leydig cells were isolated from three-week-old rats by a procedure combining collagenase dispersion, stainless steel mesh infiltration and differential adhesion. The isolated cells were cultured in DMEM/F12 and modified media for stem cell proliferation, and the proliferation of the cultured cells was evaluated by cell counting and MTP test. The expression of 3beta-HSD in the cultured cells was detected by immunohistochemistry and flow cytometry, and testosterone productivity in the isolated Leydig cells with or without hCG stimulation was determined at 2 hours and 4 days after cell isolation.</p><p><b>RESULTS</b>The Leydig cells cultured in the modified media proliferated actively, with a doubling time of (2.26 +/- .31) days, as compared with (16.32 +/- 2.14) days for those cultured in the traditional media (P <0.05). The 3beta-HSD positive rate in the cultured cells was (554.3 +/- 7.1)% after 2 hours and (93.6 +/- 4.6)% after 4 days of culture. All the proliferated cells exhibited testosterone productivity, and their testosterone secretion was significantly upregulated by hCG stimulation (P <0.05).</p><p><b>CONCLUSION</b>Leydig cells isolated by differential adhesion proliferate actively in the modified culture media.</p>

<p><b>OBJECTIVE</b>To explore the effective methods for the correction of lower eyelid retraction at different degree.</p><p><b>METHODS</b>258 patients with lower eyelid retraction were treated in our department since 1999. The lower eyelid retraction could be divided into mild, moderate and severe degree. The lateral canthal anchoring (n = 150), Hamra's lower eyelid blepharoplasty (n = 80) and translid cheek lifting (n = 28) were adopted according to the severity. The therapeutic effect for different degree of lower eyelid retraction was compared.</p><p><b>RESULTS</b>98 patients were followed up for 3-12 months, including 51 patients of mild degree, 29 patients of moderate degree, and 18 patients of severe degree. The retraction were corrected completely in 91 patients. The lower eyelid was repositioned to the level of inferior limbus without inferior scleral show when eyes opened. The palpebral fissure could close completely. The blunt lateral canthus turned to be acute and the scar was inconspicious. The retraction was improved, but not corrected completely in 3 patients of moderate degree and 4 patients of severe degree. The complications included petechiae, chemosis, and so on.</p><p><b>CONCLUSIONS</b>The lower eyelid retraction can be corrected effectively if the appropriate techniques are performed according to the degree of retraction.</p>
