Public health awareness existed in the practice of traditional Chinese medicine (TCM) long ago. In the process of Shanghai's modernization and in competition with Western medicine, TCM in Shanghai has gradually accepted the modern public health awareness, fostering its strengths, circumventing its weaknesses and playing an important role in the local public health service. To study the vicissitude of TCM public health awareness at this time will be helpful to further understand the modern history of TCM and also provide useful reference for further participation of TCM in modern public health enterprise. In this paper, the authors used literature analysis and historical research to analyze the medical practice and writings of representative TCM practitioners, medical groups and journals. The results showed that the public health awareness of TCM in Shanghai has evolved from its traditional pattern to the modern pattern seen today; the traditional pattern was characterized by individual health care and some degree of medical collaboration, whereas the modern pattern is characterized by public health education. This process was propelled forward throughout by intense national spirit. TCM has made significant contributions to the local public health service in Shanghai in the late Qing Dynasty, which promoted the modernization of public health awareness of TCM in the People's Republic of China. The authors also found that one of the ways of modernizing TCM is to diversify the ways of publicizing TCM and make it easily understood, which can shed a new light on promoting the development of TCM.

The pharmacological characteristics of recipes are multi-components, multi-ways, multi-links, and multi-targets, on which the efficacy substances in recipes are worth of studying. To explore the essential substances of Chinese herbs in recipe is one of the key points for modernization of Chinese materia medica. The pharmacological effects and bioactivities inside the target tissue of lesion body are still not clear, even though there are some progress in herb serum pharmacology, recipe pharmacokinetics, and pharmacodynamics. The main effective components of recipe to pancreas in acute pancreatitis models by ig or enema were investigated by HPLC-MS method so as to establish a new hypothesis (tissue pharmacology of recipe): i.e. guided hy fundamental theory of traditional Chinese medicine to study the effect and the mechanism of recipe's essential substances on target tissues with pharmacological methods; to establish the experimental method for searching the foundation, the principle, and the direct substances of recipes which act on target tissues; to form more effective formula if possible, and to explore in a new researching field for the recipes of Chinese materia medica.

Objective: To explore the effects of ranitidine on pharmacokinetics of rhein in rats after oral administration of Dachengqi Decoction (DCQD), a compound traditional Chinese herbal medicine. Methods: Twelve male Sprague-Dawley rats were divided into DCQD group and DCQD plus ranitidine group, and were orally administered with DCQD at a dose of 10 g/kg or DCQD (10 g/kg) combined with ranitidine (150 mg/kg), respectively. Blood samples were gathered after a series of time intervals. Metabolism of rhein was determined with a reversed-phase high-performance liquid chromatography with internal standard of 1, 8-dihydroxyanthraquinone and the data were analyzed with DAS 2.1 program. The pharmacokinetic parameters were compared between the two groups. Results: The pharmacokinetic parameters of rhein in the DCQD group, including peak concentration (C(max)), area under the plasma concentration-time curve (AUC), distribution phase half-life (t(1/2alpha)), elimination rate constant (K(10)) and central to peripheral transfer rate constant (K(12)), were significantly different to those in the DCQD plus ranitidine group (P<0.05, P<0.01). There were no significant differences in the other parameters between the two groups. Conclusion: Ranitidine can influence the pharmacokinetics of rhein in rats after oral administration of DCQD.

OBJECTIVE: To evaluate the immuno-modulatory effect of short course administration of somatostatin (stilamin) continuously at early stage in patients with severe acute pancreatitis (SAP). METHODS: Thirty-nine patients with SAP (22 men, 17 women; the middle age was 49 years)were randomly allocated into control group (20 patients treated with non-surgical integrated traditional Chinese and Western medicine) and treatment group (19 patients treated with somatostatin administered intravenously at a dosage of 250 mug/h for consecutive 72 hours as well as the treatment for the control group). Laboratory parameters, including the expressions of CD(3), CD(4) and CD(8) in lymphocytes (tested by flow cytometry) and C reactive protein (CRP), and indexes of therapeutic effect, including the occurrence of organic dysfunction, local complication and mortality between the two groups were compared. Another group of 30 healthy volunteers (19 men, 11 women; the middle age was 47 years) were recruited for testing the normal levels of CD(3), CD(4) and CD(8). RESULTS: (1) The levels of CD(3), CD(4) and CD(4)/CD(8) in lymphocytes before treatment in both groups were significantly lower than those in the healthy subjects (P<0.05), but there were no statistical differences between the two groups. At the 4th day, CD(3), CD(4) and CD(4)/CD(8) increased significantly in the treatment group (P<0.05) while no changes in the control group; the levels of CD(4) and CD(4)/CD(8) in the treatment group were also higher than those in the control group (P<0.05). (2) The CRP levels of the 2 groups showed no statistical difference before and 4 days after the treatment, but the CRP level in the treatment group was significantly lower than that in the control group at the 7th day (P<0.05). WBC count, serum levels of amylase, lipase, lactate dehydrogenase, aspartate aminotransferase, as well as the score of APACHE II in the treatment group recovered more quickly than those in the control group (P<0.05). (3) The occurrences of organic dysfunctions, local complications and mortality in both groups were not statistically different. CONCLUSION: The short course administration of somatostatin continuously at early stage can reduce the inflammatory response, up-regulate the cell immune function and improve the conditions of the patients with SAP, but its effect on mortality and morbidity needs further study.
