METHODS： Forty eight male BALB/c athymic mice models were built by Bel-7402 with an indirect method. After 24 h of postoperation, the 48 athymic mice were distributed randomly into 4 groups： A, B, C, D, each group had 12 athymic mice. Group A were were treated by intragastric administration with FT207 （Tegafur） for 4 wk. Group B, C and D were treated by intragastric administration with FJD （complex prescription of Chinese crude drug） that had been delegated into 3 kinds of density as the low, middle, and high for 4 wk. At last, athymic mice were put to death, live time, volume of tumors, exponent of tumors and the tumor metastasis in livers were observed; and PTEN was detected in hepatic tissue, latero-cancer tissue and cancer tissue by immunohistochemistry. RESULTS： Four weeks later, the total survival rate in treatment group （A ＋ B ＋ C） was 50% and higher than the control group （0%） treated by FT207, （P 〈 0.01）. The survival rate in group A, B, C was higher than in group D, and except group A with D, there was significant differentces （Fisher＇s Exact Test P = 0.05 or 0.01）. And no differences were observed between the treatment groups and the control group in volume of tumors and exponent of tumors （P 〉 0.05）. Tumor metastasis in livers of the treatment group was less than the controls （Fisher＇s Exact Test, P = 0.021）. The result of immunohistochemistry showed that the intensity of PTEN in latero-cancer tissue was the highest, and then the hepatic tissue, the lowest was cancer tissue （Kruskal- Wallis test, X^2 = 60.67, P = 0.000）. It also showed that the intensity of PTEN in treatment groups （A, B, C） was higher than the control group （D） （F = 5.90, P = 0.002 in hepatic tissue and F = 15.99, P = 0.000 in latero-cancer tissue and X^2 = 26.08, P = 0.000 in cancer tissue）, and group B is the highest in the treatment groups （P 〈 0.05, r = 0.01. respectively）. However, there was no significant statistic difference between group A and group C （P 〉 0.05）. CONCLUSION： FJD can prolong the survival time and decrease tumor metastasis in livers of these experimental mice. Mechanisms of FJD healing HCC may partially be explained by enhancing the expression of PTEN in liver.展开更多

At the same time, the world is increasingly concerned about TCM, and many studies have been conducted to investigate different aspects of TCM. Among these studies, metabolomic approach has been implemented to facilitate TCM development. The current methods for TCM research are diverse, including nuclear magnetic resonance, gas chromatography-mass spectrometry, and liquid chromatographymass spectrometry. Using these techniques, some advantageous results have been obtained in the studies of TCM, such as diagnosis and treatment, quality control, and mechanisms of action. It is believed that the further development of metabo-lomic analytical techniques is benefcial to the modernization of TCM. This review summarizes potential applications of metabolomics in the area of TCM. Guidelines for good practice for the application of metabolomics in TCM research are also proposed, and the special role of metabolomics in TCM is highlighted.展开更多

Most of researches on Wuxing theory are based on the paradigm of TCM or Traditional Chinese Culture. It is an evitable challenge to interpret Wuxing theory in the term of biomolecular, biochemistry, stem cell and so on. The oxidation of glucose is the important pathway in cell and there are five basic factors which will be responsible for the undergoing of this reaction. The relationships among these factors are similar to Wuxing theory just like inter-promotion and inter-restraint. So, this understanding on Wuxing theory maybe take some advancement for the modernization of TCM.展开更多

METHODS: Medical records of the diagnosis, surgery, and follow-up of 56 patients with anorectal melanoma who underwent surgery between 1975 and 2008 were retrospectively reviewed. The factors predictive for the survival rate of these patients were identified using multivariate analysis. RESULTS: The 5-year survival rate of the 56 patients with anorectal melanoma was 20%, 36 patients underwent abdominoperineal resection (APR) and 20 patients underwent wide local excision (WLE). The rates of local recurrence of the APR and WLE groups were 16.13% (5/36) and 68.75% (13/20), (P = 0.001), and the median survival time was 22 mo and 21 mo, respectively (P = 0.481). Univariate survival analysis demonstrated that the number of tumor and the depth of invasion had significant effects on the survival (P < 0.05). Multivariate analysis showed that the number of tumor [P = 0.017, 95% confidence interval (CI) = 1.273-11.075] and the depth of invasion (P = 0.015, 95% CI = 1.249-7.591) were independent prognostic factors influencing the survival rate. CONCLUSION: Complete or R0 resection is the first choice of treatment for anorectal melanoma, prognosis is poor regardless of surgical approach, and early diagnosis is the key to improved survival rate for patients with anorectal melanoma.展开更多
