Objective::To understand the resources distribution and varieties of crude drug Coptis chinensis Franch. on Chinese market to provide scientific basis for the resource conservation and variety collection and studies of the Chinese medicine. Methods:On the basis of literature survey, field investigation, mandatory survey and interview survey were conducted. Results:Due to the chan-ges in environment for many years and the predatory development in Coptis resources at the end of 20th century, the ecological environ-ment of wild Coptis resources changed significantly with destructed resources and decreased reserves, especially wild Yalian and Yun-lian were on the verge of extinction. The mainstream product on Chinese market was Weilian followed by Yunlian mainly used in small-scale medical clinic and medicine market in the distribution area, while Yalian commodity medicine could not found. Conclusion::The supply and demand on Coptis market should be stabilized to ensure herbalist interests. The production technology of Coptis need further improvement, cultivated area and suitable variety should be confirmed to guarantee the quality of Coptis medicinal materials. State should pay attention to the changes in Coptis resources and strengthen protection for wild Coptis resources to ensure the sustainable development of Coptis resources. Relevant government departments should guide the production of Coptis reasonably.

【Objective】 To study the incidence, possible etiology, diagnosis and prognosis of endometrial carcinoma with multiple primary carcinom a. 【Method】 45 cases of EC with other primary tumors were eligible for the ret rospective study. 【Results】 Of 1389 cases with EC, the rate of EC accompanied wit h other primary carcinoma was 3.2% (45/1389); the interval between two tumors d iagnosed was ranged from 8 months to 19 years. The percentage of interval more t han 5 years accounted for 62% (16/26). Among these 45 patients, the percentage o f EC complicated by other reproductive tract tumor was 53%(24/45), of them, 19 were synchronous carcinoma. The rate of EC with breast cancer and colo-rectal carcinoma were 169%(7/45), and 11%(5/45) respectively. Clinical staging for pati ents with EC plus multiple primary malignancy were 30 with stage Ⅰ, 9 stage Ⅱ, 3 stage Ⅲ and 2 stage Ⅳ. All patients with first primary tumors were treated by radical treatment. While 8 cases were also treated by radiation and 6 cases t reated by chemotherapy. In this group, all multiple primary tumors were treated by radical therapy. The overall 5-year survival rate was 63%. 【Conclusions】 ①The possibility of second primary tumor, such as female reproductive tract tu mor , breast cancer, and colo-rectal carcinoma should be considered in the patients with EC. ②The etiology of EC with multiple primary tumor may be relevant to th e same embryonic histogenesis, estrogen receptor, radiotherapy and chemotherapy.

Background The vitreoretinal traction plays a critical role in the formation of macular hole and cystoid macular edema.Enzymatic vitreolysis has potential in relieving vitreoretinal traction as a simple and less invasive method in comparison with pars plane vitrectomy.ObjectiveThis study is to investigate the effects of plasmin mutant with kringle domains deficiency(Plm△K)on vitreoretinal interface in new Zealand white rabbits.Methods Plm△K was prepared through activating plasminogen mutant with Kringle domains deficiency (Plg△K) by tissue plasminogen activator (tPA).100μL of Plm△K at the dose of 0.5,1.0 and 1.5μmol/min was injected respectively into the vitreous of 48 New Zealand white rabbits and 16 eyes for each dose.B-scan and optical coherence tomography (OCT) were performed to detect the structure variety at the vitreoretinal interface in 1 day and 7 days after injection.The gross anatomy analysis with triamcinolone acetonide fine particle suspension,as well as histopathological examinations by scanning electron microscopy,was performed in the different time points mentioned above.Results Two peptide chains were determined with the relative molecular weight about 26000 and 5000 by the gel imaging analysis of reduced SDS-PAGE.Separation of the posterior vitreous cortex from retina was found after intravitreous injection under the B-scan and OCT.The ultrastructure change of vitreoretinal interface as well as the examination of fine particle suspension by triamcinolone acetonide demonstrated the same outcome.The degree of remnants of vitreous cortex showed the negative correlation with the dosage of Plm△K (r=-0.9516,P=0.048).No significant correlation was found between the degree of remnants of vitreous cortex and the action time(r=-0.720,P=0.470).There was no obvious morphological difference in outer layer of retina between control eyes and Plm△K-treated eyes.No drug-related adverse event was found after intravitreous injection of Plm△K.Conclusion Intravitreous injection of Plm△K alone can induce complete separation of vitreous from retina.This procedure is safe and effective.
