Objective:This study aimed to observe the synergistic effect of a new tumor vaccine combined with metronomic che-motherapy in vivo on breast cancer. This study was also conducted to investigate the mechanism of this combination. Methods:Balb/c mice inoculated with 4T1 mouse breast cancer cell were used as tumor models. High-mobility group nucleosome-binding protein 1 (HMGN1) gene was used to transfect 4T1 cell lines as cancer vaccines. After 4T1 cell was inoculated, the mice were randomized into four groups:normal saline (NS);metronomic gemcitabine (GEM) alone;cancer vaccine alone;and combination therapy group. Tumor growth and potential toxicities of these regimens were observed. The Foxp3 expression of regulatory T cells (Tregs) was detected by western blot and immunohistochemical staining. The microvessel density (MVD) of the tumor was also detected by immunohistochemi-cal staining. Results:The tumor volume of the mice was significantly lower in the combination group than in the MET group or cancer vaccine group (P<0.05). This result exhibited a higher significant difference than the tumor volume of the mice in the NS group (P<0.01). Foxp3 expression was significantly lower in the mice treated with GEM (combination or MET group). MVD was significantly lower in these two groups than in the cancer vaccine group or NS group (P<0.05). Furthermore, adverse reactions slightly occurred in each group. Conclusion: The combination of cancer vaccines and metronomic GEM is a very active and well-tolerated regimen for breast cancer in mice.

To analyze the composition regularity of prescriptions containing Scutellaria baicalensis in Drug Standard of Ministry of Public Health of the Peoples Republic of China--Chinese Patent Medicines and Preparations on the basis of the traditional Chinese medicine inheritance support system (TCMISS), in order to provide reference for new drug R&D. the platform's software V2.0 was applied to establish a database of prescriptions containing S. baicalensis. The software's statistical statement module, association rules and improved mutual information method and other data mining technologies were adopted to analyze commonly used drugs, combination rules and core combination of S. baicalensis prescriptions. Having analyzed 477 prescriptions containing S. baicalensis, the researchers summarized 45 most commonly used drug combinations, whose ingredients mostly had functions of heat-clearing and damp-drying, purging fire for removing toxin and hemostasis. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. There were 23 diseases that S. baicalensis were most frequently applied in the treatment. Having compared three highly frequent diseases--cold, cough and dizziness, the researchers concluded that S. baicalensis could show different therapeutic effects through different combination ratios. Therefore, TCMISS (V2.0) is an important tool in analyzing the composition regularity of traditional Chinese medicines. The longitudinal and parallel comparison method is an effective method for studying the clinical composition regularity of S. baicalensis, while providing reference for new drug R&D.

OBJECTIVETo investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis.

METHODSThree EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot.

RESULTSTotally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P < 0.05).

CONCLUSIONProstatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.
