Objective To explore the clinical value of double contrast-enhanced ultrasonography (DCUS) on evaluation of the chemotherapy effect in advanced gastric carcinoma. Methods A total of 21 patients with unresectable and received chemotherapy of advanced gastric carcinoma were examined using ultrasound after taking oral contrast agent and bolus injection of Sono Vue, and findings of DCUS of each patient before and after chemotherapy were compared. Results The thickness of lesions was slightly thinner than that after chemotherapy,but there was no significant difference ( P >0. 05). In addition, there was no significant difference in the basal intensity (BI), peak intensity (PI), arrive time (AT) and time to peak (TTP) of gastric carcinoma tissues after chemotherapy (P >0.05). While the enhanced intensity (EI) value of gastric carcinoma tissues after chemotherapy was significantly less than that before chemotherapy (P <0.05). Conclusions The EI value in gastric carcinoma tissues may be considered as a sensitive and effective index in assessing the therapeutic effect of the chemotherapy in patients with advanced gastric carcinoma.

To compare the curative effects of two surgical treatment methods for open angle glaucoma and cataract patients.
●METHODS: Totally 69 patients with primary open angle glaucoma and cataract were divided into two groups:group A and group B. Thirty- four patients (34 eyes) in group A underwent small incision non -phacoemulsification cataract surgery combined with trabeculectomy, just combined operations, 35 patients (35 eyes) in group B underwent small incision non -phacoemulsification cataract surgery beyond 6mo after trabeculectomy, just two stage operations. Postoperative intraocular pressure at 1wk and 3mo, postoperative corrected visual acuity and filtering bleb at 3mo were observed, and intraoperative and postoperative complications were compared. All the patients were followed up for 3-6mo.
● RESULTS: All the visual acuity were increased compared with that before surgery in two groups, the difference was not statistically significant. All the intraocular pressure was controlled in two groups, the difference was not statistically significant, and the difference about the filtering bleb was neither statistically significant ( P > 0. 05 ). There were no serious intraoperative and postoperative complications in two groups.
● CONCLUSlON: The two stage operations and the combined operations both can control theintraocular pressure and improved visual acuity of open angle glaucoma and cataract. The two stage operations may prevent a second operation for post trabeculectomy cataract, allowing earlier visual rehabilitation.

OBJECTIVETo observe the killing effect of Herceptin and adriamycin sequentially applied on breast cancer cell line in vitro.
METHODSBT-474 human breast cancer cells in exponential growth phase were treated with Herceptin alone, adriamycin alone and their sequential administration (Herceptin before adriamycin and vice versa), respectively. Under optical microscope, the morphological changes of the cells were observed before and after drug administration. The expression rate and mean fluorescence intensity (MFI) of HER-2/neu and cell death rate were detected by flow cytometry.
RESULTSMicroscopically, the cells treated with different protocols all exhibited such changes as darkening and increase of cellular debris with irregular cell morphology. Flow cytometry revealed no significant difference in the expression rate of HER-2/neu in each group before and after treatment, but the MFI of HER-2/neu and death rate of the treated cells were significant different from those of the control group (P<0.05). The cell death rate of Herceptin-pretreated cells was significantly higher than that of adriamycin-pretreated ones (P<0.05).
CONCLUSIONHerceptin pretreatment enhances the killing effect of adriamycin on breast cancer cell line BT-474, which provides experimental evidence for designing clinical sequential biochemotherapy of breast cancer.

The osmotic pressure of ammonium sulfate solutions has been measured by the well-established freezing point osmometry in dilute solutions and we recently reported air humidity osmometry in a much wider range of concentration. Air humidity osmometry cross-validated the theoretical calculations of osmotic pressure based on the Pitzer model at high concentrations by two one-sided test (TOST) of equivalence with multiple testing corrections, where no other experimental method could serve as a reference for comparison. Although more strict equivalence criteria were established between the measurements of freezing point osmometry and the calculations based on the Pitzer model at low concentration, air humidity osmometry is the only currently available osmometry applicable to high concentration, serves as an economic addition to standard osmometry.

OBJECTIVETo find out potential molecular targets for gallbladder carcinoma diagnosis and treatment by analyzing and comparing the proteins expressed in human gallbladder carcinoma tissue and benign gallbladder tissue.
METHODSProteomic analysis of 6 human gallbladder carcinoma tissues and 6 benign gallbladder tissues was carried out. Total proteins of the carcinoma tissue and benign gallbladder tissue were separated by two-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were analyzed and identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). Immunohistochemistry was used to examine the expression of PEBP1 protein in an independent series of samples.
RESULTSProtein extracts of individual samples in each type of tissues were separated on two-dimensional gels. There were forty six differentially expressed proteins in the gallbladder carcinom tissues. Seventeen proteins were successfully identified by MS, in which nine proteins were overexpressed in tumors while the other eight proteins were underexpressed. The increased level of PEBP1 protein in gallbladder carcinoma was further confirmed by immunohistochemical analysis.
CONCLUSIONSeventeen differentially expressed proteins were successfully characterized by comparative proteomic analysis. Those results may provide scientific foundation for screening the molecular biomarkers which can be used in diagnosis and treatment of gallbladder carcinoma, as well as to improve its prognosis and provide a new clue for carcinogenesis research of gallbladder carcinoma.
