Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

OBJECTIVETo investigate the relationship between serum sex hormone levels, liver function, and pathogenic mechanisms related to cutaneous lesions involving the facial skin in male patients with liver cirrhosis.
METHODSFifty male cirrhotic patients with facial skin lesions, including spider angiomas, angiotelectasis and special type rash, (mean age: 48.1 +/- 12.2 years) were randomly selected for study and enrolled as the case group. Thirty cirrhotic male patients without facial skin lesions (mean age: 44.5 +/- 11.7 years) were enrolled as the control group. Serum levels of luteinizing hormone (LH), follicular stimulating hormone (FSH), prolactin (PRL), estradiol (E2), progesterone (PRGE), and testosterone (T) were detected and compared between cases and controls by the t-test. All patients were sub-categorized according to severity of cirrhosis (Child-Pugh classification) and comparisons between cases and controls were carried out by single factor analysis of variance. Logistic regression modeling was used to evaluate whether the presence of skin lesions is related to changes in markers of liver impairment, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), serum albumin (Alb), prothrombin time (PT-SEC), creatinine (CREA), platelet count (PLT), and alcoholism.
RESULTSIn the cases with spider veins, LH level was significantly elevated (t = 2.01) and T level was significantly decreased (t = -2.20) (both, P less than 0.05 vs. controls). In the cases with telangiectasia, the LH level (t = 3.76, E2 (t = 2.08) and E2/T ratio (t = 2.98) were significantly elevated and T level was significantly decreased (t = -3.77) (all, P less than 0.05 vs. controls). In the cases with special type rash, FSH level was significantly elevated (t = 2.03) and T level was significantly decreased (t = -2.01) (both, P less than 0.05 vs. controls). In the case group, E2 levels decreased as severity of liver damage increased, while in the control group, E2 levels increased as severity of liver damage increased; however, the difference in average E2 values of the two groups did not reach statistical significance (P more than 0.05). In both cases and controls, the T levels were decreased as the severity of liver damage increased (F = 3.70, P less than 0.05). Multivariate logistic regression analysis showed that increased incidence of facial skin lesions is associated with alcoholism (odds ratio (OR) = 4.46, 95% confidence interval (CI) = 1.45-13.7, P less than 0.05) and elevated serum levels of AST (OR = 11.87, 95% CI = 1.24-113.1, P less than 0.05).
CONCLUSIONAlcoholism, impaired liver function, and perturbed levels of circulating sex hormones are associated with cirrhosis-related facial lesions and may play important roles in the pathogenesis of cutaneous lesions in patients with cirrhosis.
