Objective To establish an effective qualitative discrimination method for Selaginella medicinal materials.Meth- ods Thin layer chromatography(TLC)method was used.Results The TLC method has a good specialization for identifying Selaginella medicinal materials and can distinguish Selaginella rnoellendorfii from other 10 familiar species in northern areas of Guangdong province.Conclusion The method can help to control the quality of Selaginella moellendorfii Tablet.

Objective To report initial experience and the indications of retroperitoneal laparoscop- ic partial nephrectomy.Methods From December 2001 to October 2005,23 patients (including 14 cases of renal cell carcinoma,5 of hamartoma and 4 of duplex kidney) underwent retroperitoneal laparoscopic par- tial nephrectomy.One of the patients had solitary kidney.Results All the operations were successful ex- cept for only 1 requiring conversion to laparoscopic nephrectomy because of bleeding resulting from blocking anterior branch of renal artery.The mean operative time was 121 min (60-240 min),and mean ischemic time was 32 min (20-55 min).The estimated bleeding volume ranged from 100 ml to 300 ml,and no pa- tient needed blood transfusion.Pathology showed negative surgical margins in 14 cases of renal cell carcinoma and confirmed the diagnosis of hamartoma in 5 cases.One patient with duplex kidney required open partial nephrectomy because of renal cystic mass resulting from incomplete resection.Conclusions Retroperito- neal laparoscopic partial nephrectomy offers a new effective and minimally invasive treatment for selected pa- tients with renal mass.The long-term effects of the procedure need further investigation.

OBJECTIVETo probe into and improve the diagnosis and treatment of tuberculosis (TB) in the male genital system.
METHODSFifteen patients with the male genital system TB established by microbiological and pathological examinations were retrospectively reviewed.
RESULTSThe male genital system TB was diagnosed by history, physical examination, semen analysis, TB culture and biopsy. Treatment consisted of antituberculous chemotherapy for all the patients before and/or after operation, including 5 cases of epididymectomy and 6 cases of orchi-epididymectomy.
CONCLUSIONThe male genital system TB tends to be atypical and semen polymerase chain reaction of TB (TB-PCR) may provide a new specific means for diagnosis in case of clinical suspicion. Surgical approaches should be cautiously adopted, especially for young patients.

【Objective】 To explore the status quo and influencing factors of knowledge, attitude and practice of voluntary blood donation among undergraduates in Beijing. 【Methods】 A questionnaire was designed on the basis of literature, using the method of convenience sampling to survey the undergraduates from 39 universities in Beijing. The t-test, analysis of variance and χ2 test were used to compare the differences in knowledge, attitude and practice of voluntary blood donation among different groups, and logistic regression model was performed to analyze the influencing factors. 【Results】 A total of 1 075 valid questionnaires were collected from undergraduates of 39 universities in Beijing. The results showed that the proportion of the participants who had good knowledge about voluntary blood donation was 69.21% (744/1 075). No statistically significant difference was noticed on the scores of voluntary blood donation knowledge between males and females (P>0.05). The scores of voluntary blood donation knowledge of medical students were higher than those of other subjects (P<0.05). The scores of voluntary blood donation knowledge of juniors and above were higher than those of lower grades (P<0.05). The rate of undergraduates participating voluntary blood donation in Beijing was 30.98% (333/1 075). A total of 67.26% (723/1 075) of students had donation intention, 9.49% (102/1 075) didn’t and 23.25% (250/1 075) were not sure. No statistically significant differences in blood donation intention were observed among undergraduates by genders and grades (P>0.05). The rate of medical students’ intention to donate blood was higher than that of other subjects (P<0.05). 【Conclusion】 The rate of voluntary blood donation among undergraduates in Beijing was above the middle level compared with other regions in China, but the practice of voluntary blood donation is far away from the intention. Therefore, it’s necessary to improve the level of knowledge, attitude and practice of undergraduates, especially non-medical college students, so as to improve the rate of voluntary blood donation among the undergraduates in Beijing.
