Individual stature estim ation is one of the m ost im portant contents of forensic anthropology. C urrently, it has been used that the regression equations established by the data collected by direct m ea-surem ent or radiological techniques in a certain group of lim bs, irregular bones, and anatom ic landm arks. D ue to the im pact of population m obility, hum an physical im provem ent, racial and geographic differ-ences, estim ation of individual stature should be a regular study. T his paper review s the different m ethods of stature estim ation, briefly describes the advantages and disadvantages of each m ethod, and prospects a new research direction.

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.

Objective To discuss the clinical features diagnosis and treatment of cerebral schistosomiasis. Methods A to?tal of 166 patients with cerebral schistosomiasis were treated and their clinical data were collected and analyzed retrospectively. Results In 166 cases of cerebral schistosomiasis the confirmative diagnoses of 156 cases were diagnosed according to the clin?ical manifestation etiology immunology and auxiliary examination CT MRI .In among 74 cases were confirmed by pathologi?cal examination 10 cases were diagnosed through to the diagnostic treatment. Totally 102 patients received the oral medication of praziquantel and they all improved and discharged 14?16 days later 64 patients received the craniotomy and praziquantel medication after the operation and 48 patients significantly improved others did not improve or aggravated. There was no opera?tive mortality. Conclusions Neuroimaging and laboratory tests are valuable in the diagnosis of cerebral schistosomiasis. The praziquantel treatment is selected firstly when the diagnosis was established. However in the case of serious intracranial hyper?tension intractable epilepsy and praziquantel treatment fails the surgical treatment is required.

Objective To investigate the expressions of PTEN and MDM2 in bladder transitional cell carcinoma (BTCC) and their clinical significance.Methods The expressions of PTEN and MDM2 were detected by tissue immunohistochemistry test (SP method) in BTCC (n =80) and normal bladder tissues (n =20).The relationship between PTEN and MDM2 as well as their correlations with clinical pathological features were analyzed.Results The positive rate of PTEN in different pathological grading (G1,G2,G3)and clinical staging [superficial (Tis ～ T1),infiltration (T2 ～ T4)] was (86.20％,74.07％,37.50％ ;80.00％,46.67％),respectively,with a significant difference (x2 =15.004,P ＜ 0.01 ; x2 =9.497,P ＜0.01).The positive rate of MDM2 in different pathological grading(G1,G2,G3) and clinical staging [superficial (Tis ～ T1),infiltration (T2 ～ T4)] was (82.75％,55.55％,37.50％ ; 70.00％,43.35％),respectively,with a significant differcnce(x2 =11.543,P ＜ 0.01 ; x2 =5.556,P ＜ 0.05).The expression of PTEN was negatively correlated with that of MDM2 in BTCC (r =-0.611,P ＜ 0.05).Conclusions Expressions of PTEN and MDM2 might be involved in the BTCC pathogenesis.The combined detection of PTEN and MDM2 might be of great value in the prediction of tumor behavior and prognosis.

Objective To investigate factors affecting the metastasis of lymph nodes around the root of inferior mesenteric artery(IMA) in rectal cancer,and the significance of root lymph nodes dissection of IMA in radical surgery for rectal cancer.Methods Clinicopathological data of 105 rectal cancer patients undergoing root lymph node dissection of IMA during radical resection in Peking University First Hospital from January 2005 to December 2008 were analyzed retrospectively.Rectal cancer patients without root lymph node dissection of IMA during the same period served as control.Results were compared between these two groups for survival and local recurrence rates.Results The rate of lymph node metastasis around the origin of IMA was 9.5％ (10/105).The five-year survival rate in patients with IMA root nodal dissection was 71.3％,and that without was 70.6％ (P =0.995),while the local recurrence was respectively 1.9％ and 7.4％ (P ＜ 0.05).In multivariate analyses,IMA root nodal metastasis occurred more frequently in patients with pT3 and pT4 tumor(Wald =5.764,P ＜ 0.05) and poorly differentiated tumor(Wald =7.818,P ＜ 0.05).Conclusions Root lymph nodes dissection of IMA could not increase five-year survival rate,but it could reduce local recurrence rate in patients with rectal cancer.In radical surgery of rectal cancer,lymphadenectomy of IMA root should be performed in patients with T3 and T4 tumor with poorly differentiated tumor,so as to reduce local recurrence rate.
