Objective:To establish a method for the determination of nimesulide granules by HPLC. Methods:An Inertsil ODS-SP C18 column(250 mm × 4. 6 mm,5 μm) was used, and the mobile phase was 0. 01 mol·L-1 potassium hydrogen phosphate anhy-drous-acetonitrile(55∶45)[adjusting pH to (7. 2 ± 0. 05) with phosphoric acid]. The detection wavelength was set at 399nm and the flow rate was 1.0 ml·min-1. The injection volume was 20 μl. Results: The linear range of nimesulide was 0.044-0.222 μg(r=0. 999 9), the average recovery was 99. 22% and RSD was 0. 46%(n=6). Conclusion:The method is simple, accurate with promis-ing sensitivity and reproducibility, and can be used in the determination of nimesulide granules .

Primary liver cancer is one of the most commonly seen tumors in clinical practice. Due to the stealthiness and fast progress of liver cancer, only 20% of the patients may have chance to receive operation for radical therapy. Patients seldom get benefit from systematic chemotherapy and as a result, local chemotherapy methods such as transarterial chemoembolization (TACE) have become the mainstay in the treatment of liver cancer. Compared with systematic chemotherapy, TACE produces fewer side effects and most of such side effects are caused by postembolization syndrome manifested as nausea and vomiting, abdominal pain, fever, loss of appetite, etc.

To improve the preparation speed and quality of moxa cone, a mould for preparation of moxa cone was designed and applied in moxibustion. It consists three parts: a foundation (a flat-bottomed circular cylinder hollow in center), a moxa cone forming tube (a hollow column encircled by two semi-cylinders with symmetrical shape and size, and was inserted in the internal cavity of the foundation); and a compression rod (a solid cylinder used for compressing moxa placed in moxa cone forming tube). The mould is practical, simple, and convenient and can effectively speed up the preparation of moxa cone, and it is safe in application. Moreover, the obtained moxa cones are regular in shape, uniform in dosage and size, dense in texture, and convenient to pack, store and carry.

Objective To extract the color feature of tongue image.Methods The tongue image was divided into 8?8 dynamic rectangular grids. Then the color histogram of each grid was calculated. All of them composed a high-dimensional vector (we call it the original feature vector).Finally, the dimensionality of the original feature vector was reduced by using Landmark Isomap. Results Experiments on 3 594 tongue images showed that several color features of tongue image, such as the color of tongue substance, the color of tongue coat, the shades of tongue color, and so on could be extracted. Conclusion This proposed method can be used to extract the color feature of tongue image effectively.

Guidelines of Prevention and treatment of Children's Influenza A (H1N1) with TCM includes four parts of prevention, diagnosis, clinic treatment and nursing. The drug prophylaxis stresses on administration by identified body without diseases, which includes normal constitution, qi-deficiency constitution, inner-heat constitution and phlegm-damp constitution, children of different constitution are given different appropriate drugs. The treatment bases on syndrome differentiation, such as mild syndrome, severe syndrome, crises and convalescence. The syndrome-classification includes wind-heat invading the exterior, dampness obstructing defensive qi, the heat-toxin blocking the lung, exuberant toxin in both qi and ying, deficiency of heart-yang, the evil sinking into jueyin, residual evil remaining in the body and the deficiency of both qi and yin. The nursing emphasizes the isolation, keeping body warm, bland diet and nursing during convalescence.

To explore the characteristic genomics of syndrome of liver-kidney yin deficiency in peripheral blood mononuclear cells of hepatocellular carcinoma (HCC) patients.

AIM: To study the technological parameters of the purification process of total flavonoids of Crataegus leaves with HPD-600 macroreticular resin. METHODS: Using orthogonal experiments,the adsorptive characteristics and elutive parameters of the process were studied by taking the elutive effects and purification ratio of total flavonoids of Crataegus leaves. RESULTS: Two significant factors which were the concentration of crude flavonoids solvent and elutant component were observed. CONCLUSION: The microwave-assisted extraction and purification process with macroreticular resin is employed,the content of total flavonoids is 80.75%, the rutin content is (1.38)%, The macroreticular resin can be used in the purification of flavonoids of Crataegus leaves.

Object To study the effect of melittin on growth and proliferation of hepatocarcinoma cells. Methods Hepatocarcinoma cell line SMMC7721 was treated by melittin. The growth and proliferation was observed by cell counting and MTT assay; necrosis was estimated by Trypan blue staining. The expression of proliferating cell nuclear antigen (PCNA) and cycle phase were detected by flow cytometer. Results Melittin could significantly inhibit the growth of SMMC7721 and block up cells progress through G 2/M. The percentage of PCNA positive cell was decreased gradually when concentration of melittin was increased. Conclusion Melittin could inhibit the proliferative activity of hepatocarcinoma cell line SMMC7721 and reduce of PCNA positive cell expression and arrest cells in S phase.
