OBJECTIVETo improve the diagnostic ability of routine laboratory items in liver diseases associated with viral hepatitis through constructing assessment models consisting of these items.

METHODS(1) Assessment of routine items and formulation of models. Data of 447 patients seen between May 1997 and August 2003 were collected as the training set and serum specimens of 213 patients taken between June 2004 and March 2005 were examined and used as the validation set. Eleven items (TP, ALB, TBIL, DBIL, ALT, AST, ALP, GGT, TBA, LDH, CHE) were examined with an automated biochemical analyzer. Logistic regression was applied to construct the model for discriminating between chronic hepatitis and liver cirrhosis. The diagnostic value of items and models was assessed by the area under the receiver-operating characteristic (ROC) curve.

RESULTSThe model to discrimination between chronic hepatitis and liver cirrhosis consists of five items (CHE, DBIL, ALB, ALT, GLO). The AUCs of model were 0.87 in the training set and 0.83 in validation set, respectively.

CONCLUSION(1) The model consisting of CHE, DBIL, ALB, ALT, GLO improves the diagnostic value of routine laboratory items in discriminating chronic hepatitis from liver cirrhosis.

Objective To study the clinical and imaging features of patients with bone metastases from breast cancer and identify the factors related to the incidence of bone metastases. Methods Three hundred and thirty-four patients with breast cancer were recruited into this study. Whole-body 99Tcm-methylene disphosphonate (MDP) bone scan, clinical staging, pathological, immunohistochemical and serological test results were analyzed retrospectively. χ2 test was used for statistical analysis. Results The incidence rate of bone metastases for patients with and without lymph node metastases was 71% (152/214) and 22. 5% (27/120), respectively (χ2 =72.80, P =0.000). The incidence rate of bone metastases from infiltrated non-specified and specified breast cancer was 69% (203/294) and 41.7% (5/12), respectively (χ2 =3. 97, P=0.046). Alkaline phosphatase (ALP) was elevated in 28.5% (51/179) and 14.9%(11/74) of patients with and without bone metastases, respectively (χ2 = 5. 25, P = 0.022 ). Carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 15-3, CA125, CA19-9 increased in 68.7% ( 123/179) and 27.0% (20/74) of patients with and without bone metastases, respectively (χ2 = 37. 03, P =0. 000). Conclusions The incidence of bone metastases from breast cancer is correlated to pathological types of primary tumor and lymph node metastases. Bone metastases occurs more frequently in patients with infiltrated, non-specified, primary cancer and with lymph node metastases. Serum ALP, CEA, CA15-3,CA125, CA19-9 might be the tumor makers for early diagnosis of bone metastases from breast cancer.

OBJECTIVETo compare the efficiency of three different estrogen receptor (ER) immunostaining scoring systems by analyzing the correlation between ER status and clinicopathologic features for prediction of prognosis of patients with endometrial carcinoma (EC).

METHODSER immunostaining (EnVision method) was performed in 160 type I EC and 39 type II EC paraffin samples and was scored by ASCO/CAP criterion, H-Score and Allred scoring system. Correlation between ER status and clinicopathologic features was statistically analyzed.

RESULTSASCO/CAP criterion, H-Score and Allred (cutoff point: 4-8) scoring system showed high concordance in the following aspects. In EC patients, ER status was significantly associated with presurgical CA125 levels (P = 0.015, P = 0.007, P = 0.023), histologic grades (all P < 0.01) and PR status (all P < 0.01). In type I EC cohort, ER status was significantly correlated with PR status (P = 0.008, P < 0.01, P < 0.01) and p53 status (P = 0.042, P = 0.001, P < 0.01). As of the predictive value of ER status for type I EC patient age, ASCO/CAP (P = 0.027) and H-Score criteria (P = 0.035) were both superior to Allred score system (P = 0.064). Among well-known predictive clinicopathologic parameters, including FIGO stage, lympho-vascular involvement, lymph node metastasis, depth of myometrial invasion and omental involvement, ASCO/CAP scoring offered a better correlation (P = 0.005, P = 0.002, P = 0.021, P = 0.067, and P = 0.067, respectively) than H-Score (P > 0.05) and Allred scoring system (P > 0.05).

CONCLUSIONSCompared with H-Score and Allred scoring system, ASCO/CAP criterion is more closely correlated with predictive clinicopathologic parameters. Therefore it may be used as a simple, highly efficient prognostic indicator for EC patients in routine practice.

"Dida" is one of the most representative commonly used Tibetan medicines in treatment of hepatobilaiary diseases. To analyze and compare the content of 7 effective constituents in 11 species which are used as Dida. Integrated evaluation of them, which supply a basis for the resources exploitation for them. In this paper, most appropriate absorption wavelengths of different natural iridoid compounds, xanthones and oleanolic acid have been performed by using 3D spectrum technique. According to the results, the wavelength 210, 240 and 265 nm were used for detection of 7 effective constituents. By means of calculation, determination of 7 effective constituents indicated good linearity over the linear range with coefficients (r) of 0.999 9 respectively. The recoveries were found in the average range of 99% to 101% with RSD being less than 3%. Normalize and integrate by three-dimension the data. Get their integrated chemical quality index(ICQI). Results suggested that these plants used as Dida in Tibet medicine mostly contain these 7 effective constituents, but the different is notable. The integrated evaluation by the integrated chemical quality index (ICQI) has reference value for quality control.

Paris is a commonly used traditional Chinese medicine (TCM), and has antitumor, antibacterial, sedative, analgesic and hemostatic effects. It has been used as an ingredient of 81 Chinese patent medicines, with a wide application and large market demand. Based on the data retrieved from state Intellectual Property Office patent database, a comprehensive analysis was made on Paris patents, so as to explore the current features of Paris patents in the aspects of domestic patent output, development trend, technology field distribution, time dimension, technology growth rate and patent applicant, and reveal the development trend of China's Paris industry. In addition, based on the current Paris resource application and development, a sustainable, multi-channel and multi-level industrial development approach was built. According to the results, studies of Paris in China are at the rapid development period, with a good development trend. However, because wild Paris resources tend to be exhausted, the studies for artificial cultivation technology should be strengthened to promote the industrial development.

Objective:To established an approach of chemical fingerprinting and study the differences of the polysaccharides from three species of Polygonati Rhizoma in Chinese Pharmacopoeia,so as to provide reference for quality evaluation and clinical application of Polygonati Rhizoma. Method:The polysaccharides were extracted by water extraction and alcohol precipitation from Polygonati Rhizoma. After hydrolysis by trifluoroacetic acid (TFA) and pre-column derivation by PMP,the chromatographic fingerprints of three kinds of Polygonati Rhizoma were established by high performance liquid chromatography. The fingerprinting model and chemometrics method,include similarity analysis (SA),cluster analysis (HCA) and principal component analysis (PCA) were used for compare the differences among three species. Result:There were some differences in the PMP-HPLC fingerprints and monosaccharide composition from the three species. The D-mannose,L-rhamnose and L-fucose were not detected,but they all contained D-galacturonic acid,D-glucosamine hydrochloride,D-galactose,D-glucose and D-xylose among three species. The PCA and HCA analysis showed that chromatographic fingerprints of P. cyrtonema and P. sibiricum were similar,while P. kingianum and other two species were significantly different. Conclusion:There are differences in fingerprints of polysaccharides among three species of Polygonati Rhizoma. The possible effects of species should be considered in clinical application. The established PMP-HPLC is a simple,accurate and reproducible method,which can be used for the quality evaluation of Polygonati Rhizoma.
