Citrus aurantium is one of the most common traditional Chinese medicines. In this paper, the chemical components, content determination and pharmacological actions of C. aurantium were summarized for the comprehensive utilization of its resources. Because of the complicated resources of C. aurantium, only one single component as index couldn't reflect the quality and effects and comprehensive evaluation which concluding multiple components should be established in the future quality control. In recent years, the pharmacological effects research of C. aurantium has made tremendous progress, and it is important to explore new drugs from the development and utilization of the active ingredient of C. aurantium.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

The aim of this research is to investigate the influence of microencapsulation on the expression of the oxidative stress genes and exogenous regulation of HepG2 cells. We compared the expression of hemeoxygenase-1 (HO-1) and glutathione S-transferases-A1 (GST-A1) in HepG2 cells under different culture conditions through real-time PCR. The effects of exogenous antioxidants on cell viability and albumin levels were also evaluated through MTT assay and ELISA assay. The results showed that after culturing for 6 and 16 days, the expression levels of HO-1 in encapsulated cells were approximately 4.9 and 3.1 times higher than that of monolayer cells at the same culture period; As for the expression levels of GST-A1, they were elevated to 11.2 and 33 times of monolayer cells (P < 0.05). Accordingly, we found that NAC at 5-10 mmol/L significantly increased the viability by 40%-70% and the biosynthetic function by 20%-30% in microencapsulated HepG2 cells (P < 0.05). GSH increased the viability of the encapsulated cells by 20%-55% and the biosynthetic function by 15% (P < 0.05). In conclusion, oxidative stress exists in the microcapsules and affects genes expression. Exogenous antioxidants can prevent the inhibition effects of oxidative stress on cellular growth.

Objective To report the clinical features a nd pathologic findings of 1 case of mixed epithelial and stromal tumor of the ki dney. Methods The patient who had a 20-year history of taking oral contraceptive was a 50-year-old woman with pain in left flank asso ciated with hematuria for half a year.CT and MRI revealed an 8 cm?6 cm cystic a nd solid mass located in the upper pole of the left kidney.A diagnosis of cystic renal carcinoma was made before operation.Radical left nephrectomy was performe d in July 2004. Results The upper pole of the left kidne y was found severely adhesive with peripheral tissues du- ring operation.Gro ssly,the tumor exhibited a 7.9 cm?8.9 cm?9.0 cm multilocular cyst full of coff ee- colored mucoid fluid with varying size ranging from 0.5 to 2.0 cm.Focall y thick-walled cysts with solid areas were seen.Microscopic findings showed the tumor was composed of a mixture of stromal elements formed by spindle cells and epithelial elements that were variable in cell types including cuboidal,columna r and hobnail cells.Differentiation of gastrointestinal tract was found in epith elial elements.Thick-walled blood vessels and distinctive bands of smooth muscl e cells were present in the stromal elements.Immunohistochemical staining reveal ed that the epithelial component was positive for AE1/AE3,and stromal component was positive for ER,PR,and SMA.No specific treatment was given and the patient w as free of signs of recurrence 8 months after operation. Conclusions Mixed epithelial and stromal tumor of the kidney is recognized to b e a kind of benign neoplasm.Differentiation of gastrointestinal tract in epithel ial elements is rare.It should be distinguished from any other benign and malign ant tumors in the kidney.
