Patent documentation is a kind of high-value scientific literature. In this paper, the World Traditional Medicine Patent Database (WTMPD) was used to retrieve patents of the traditional medicines used in the treatment and prevention of alcoholic worldwide in the past 30 years. A total of 3 238 patents were further screened by a se-ries of processes. Finally, multi-angle analysis was carried on the dataset to form a patent analysis report on tradi-tional medicines used in alcoholism, including the distribution of the patents, the application trend, the domestic and foreign geographical layout, the major applicant and so on. From the analysis, we found that China had a rapid in-crease in the number of patent applications, which was in the leading role in the world, though the technology and the number of PCT applicant from China is relatively low. Puerariae Lobate radix and flos are frequently used in al-coholism patents.

AIM: To apply UASLG for Rana temporatia chensinensis David's identification. METHODS: Rana temporatia chensinensis David was made ultrasonic extraction. These solvents in turn were petroleum ether、chlorofo mn、ethyl acetate、n-butanol and 95%WTBZ# ethanol,then their absorbance in UV and one-order derivative spectrums were determined. RESULTS: Rana temporatia chensinensis David's UASLG was reproducible. CONCLUSION: UASLG's action spectrums for Rana temporatia chensinensis David can be identified for quality control.

OBJECTIVETo discuss the problem about the origin of Oviduetus Ranae in the Chinese Pharmacopoeia according to historical documents, the researches reported recently and the author research.

METHODThrough comprehensive analysis of the documents and materials reported, the original animal sources of Oviduetus Ranae was discussed in terms of historical records, morphology, karyotype, Ag-Belt and isoenzyme electrophoresis, gene levels and so on.

RESULT AND CONCLUSIONThe original animal sources of Oviduetus Ranae is Rana dybowskii,its order element is an effective species in China. In order to avoid the problem of species confusion about the origin of Oviduetus Ranae, author suggests that R. dybowskii should be the original animal of Oviduetus Ranae.

The discovery of high performance leading antidiabetic compounds containing sulfonamide and 4-aminophenylacetic acid moieties is reported. This was achieved by the synthesis of 6 intermediates and subsequently 20 target molecules using 4-aminophenylacetic acid as the starting materials, and through a few synthetic routes aided by multi-step reactions including sulfonylation of amino group, deacylation of amides and esterification of carboxyl group, as well as acylation of amino group. The chemical structures of the twenty-four new compounds were determined using 1H NMR, 13C NMR and HR-MS techniques. Screening in vitro of their peroxisome proliferator-activated receptor (PPAR) activation activities showed weak relative PPAR activation activities to most of the target molecules. However, 4 target molecules exhibit PPAR over 58%, and as high as 81.79% for TM2-i, presenting itself as potent leading compound for antidiabetic drugs. This research also confirms that it is probable to achieve esterification of carboxyl group and deacylation of fatty acid N-phenyl amides concurrently in SOCl2/alcohol solvent system. This provides new synthetic method for the selective reaction within molecules containing both carboxyl and N-aryl amido groups of fatty acids.

Objective To evaluate the significance of AFP-IgM, this is one of new tumor markers, in the diagnosis of primary hepatocellular carcinoma (PHC). Methods The contents of AFP-IgM and AFP in serum of 103 healthy subjects, 74 patients suffered primary hepatic carcinoma, 27 patients affected by liver cirrhosis and 63 patients affected by chronic hepatitis were detected by means of enzyme linked immunosorbent assay and electrochemiluminescence. No-PHC is comprised of liver cirrhosis,chronic hepatitis and health subjects as control group. Results The area under ROC curve of AFP was larger than that of AFP-IgM (0.85 vs 0.72, Z=3.21) and the best cut-off value of AFP-IgM and AFP was 3×105-AU/L and 10 ug/L respectively, which was determined by ROC curve. Under the cut-off value, the sensitivity of AFP- lgM and AFP for PHC were 64.9% and 79.7%, and the specificity were 75.6% and 80.3%, yet their efficacies were similar. However, for early diagnosis of liver cancer (stage Ⅰ and Ⅱ), the area under ROC curve of AFP-IgM was larger than that of AFP (0.91 vs 0.82,Z=1.73). The sensitivity of AFP-IgM andAFP were 94.4% and 72. 2%, and the specificity were 81.9% and 79.9%. The differences of AFP-IgMand AFP for early diagnosis of liver cancer were statistically significant. When both of the test results combined AFP-IgM with AFP are positive, it can be diagnosed as liver cancer. The specificity of combineddetermination of the two forms was 89.1%, and the efficacy was 79. 0%. Conclusions Both of thesensitivity and specificity of the AFP-IgM test were higher than that of the AFP for early diagnosis of livercancer. We also found that combined determination of the two forms significantly increased the specificityand the positive predictive value for the diagnosis of PHC, thus AFP-IgM was of especially significance forearly diagnosis of liver cancer.
