Hapten-carrier protein conjugates were made using ciprofloxacin (CPFX) and two carrier proteins by 1-ethyl-3-(3- dimethylaminopropyl)-carbodiimide hydrochloride (EDC) method. Ultraviolet spectrophotometry were used to demonstrated that the molecule conjugate ratio of CPFX to ovalbumin (OVA) and bovine serum albumin (BSA) are 6:1 and 13:1 respectively. Nondenaturing gel electrophoresis results revealed that the conjugate band migrates differently from that of the carrier protein alone and of the EDC-treated protein when as few as 6 molecules of CPFX are attached to the carrier protein. The results indicate that nondenaturing gel electrophoresis and ultraviolet spectrophotometry can be employed to analyze the molecule coupling ratio of CPFX to carrier proteins qualitatively and quantitatively.

Objective As a classical approach for hyperthermic ablation,microwave ablation (MWA) has been widely used in the treatment of tumors that cannot be removed by traditional surgery.MWA devitalizes the neighboring tissue and kills tumor cells by thermal diffusion.In the last two decades,this technique has been improved for treating malignant bone tumor in our institute.In situ ablation has already replaced en bloc resection and achieved satisfactory treatment outcomes.This study explores whether tumor cell death induced by MWA would cause the release of immunogenic tumor antigens and tumor-specific immune responses.Methods Three models of MWA were established using osteosarcoma cell lines from the mouse,rat,and human,respectively.The expression of immunogenic molecules was measured during in vitro and in situ ablation with different ablation time and group design.Results The injection of tumor vaccines made from tumor cells or supernatant treated with in vitro ablation resulted in substantial inhibition of tumor cell growth in tumor-bearing animal models.The CDs + T cells induced by vaccines played a key role in the process.The effector cells released cytokines,IFN-γand TNF-α,to inhibit tumor cell growth and also trigger Fas/FasL-mediated apoptosis.Conclusions MWA-treated osteosarcoma cells can be used to induce specific antitumor immunogenic effects.Therefore,in situ MWA combined with immunotherapy provides an alternative treatment method for patients who have trouble due to their insensitivity to chemotherapy.

Objective To study the mechanism of serum thyroxin and insulin change after hemihepatectomy. Methods The hemihepatectomy was performed in rabbits, the fasting peripheral blood samples were drawn on the day prior to surgery, and 24 hour, 48 hour, the first week, one month after operation respectively for monitoring the serum thyroxin and insulin.Results The level of TT 3 was (1.93?0.47) nmol/L, TT 4 (53.56?8.4) nmol/L preoperatively. The levels of TT 3 and TT 4 significantly decreased at 24 hour postoperatively, and gradually rose at 48 hour and up to normal levels in the first month postoperatively. The level of insulin rapidly rose immediately after operation, and began to decrease in the first week, and returned to the preoperative level in one month after operation. Conclusions The syndrome of normal thyroid disease and the syndrome of non thyroid disease can occur after hemihepatectomy; and hyperinsulinemia also can occur after hemihepatectomy.

To screen the illegal substances in fishery inputs,we established the database including the precursor and the daughter ions for these possible components by the quadrupole/orbit-trap mass spectrometer,and the retention time of each drug on the same chromatographic column.And then,the extracted and diluted samples were analyzed and the components in the real samples were identified under the same conditions.Chromatographic analysis was performed on an Accucore RP-MS column (100 mm × 2.1 mm,2.6 μm) using gradient elution with 0.1% formic acid in water and 0.1% formic acid in acetonitrile as mobile phase.Elutes were ionized through heatable electrospray ionization (HESI) in both positive and negative mode simultaneously.Data acquisition was conducted by Full-scan ddMS2 (TopN) mode,in which the full mass profile for a continuous precursor ion injection and the fragments of each high abundant precursor of targeted were acquired with excellent time and mass resolution.Screening was carried out through comparison of the information of real samples with that of standards in the database,which were processed by software (Tracefinder).The Quantification of each component was analyzed based on the precursor ion chromatography acquired by orbit-trap mass spectroscopy,which showed a good linearity between 0.01-1 μg/mL,with R>0.98.The method was validated by checking its minimum screening concentration (0.5 mg/L for drugs and 5 mg/L for feedstuffs) and evaluating the recovery after addition of the standard mixture in real samples (>50%,under the addition of 10 and 100 mg/kg).The results for 68 practical samples demonstrated the effective performance of this method for screening with high-throughput,rapidness and acceptable minimum screening concentration and accuracy,in which 15 of 29 fishery drug samples were screened out for positive components that were not indicated in their labels.

Background Light-induced retinal damage results in the damage of retinl pigment epithelial (RPE) cells and therefore affects the pathogenesis and development of age-related macular degeneration (AMD).Studies showed that tissue factor (TF) is overexpressed in oxidative damaged RPE cells and the choroidal neovascularization (CNV) of AMD,speculating that the suppression of TF can prevent the damage of RPE cells and inhibit CNV.Objective This study was conducted to observe the protective effects of TF targeting peptide (TFTP),a new drug of autologous synthesis,on human RPE-cells induced by blue light.Methods Human RPE cells were isolated from donor eye and cultured.Cultured cells were divided into blank control group,model group and TFTP treated group.Light-induced RPE cell damage model was established by exposuring the cells in the blue light of (4.0±-0.5) mW/cm2 for 12 hours in the model group,and different concentrations (10,100,150,200,300 μmol/L) of TF-TP were added into the medium to pretreat the cells for 24 hours and then exposed the cells to the blue light for 12 hours in the TF-TP groups.The cell viability was determined by CCK-8 assay.The morphology and ultrastructure in the cells were observed under the inverted microscope and transmission electron microscope.The apoptosis of the cells was assayed by Hoechst staining.The expressions of TF and apoptosis-related protein bax,bcl-2 in the cells were determined by Western blot.Results CCK-8 assay showed that there was no significant difference in the cell viability among blank control group and different concentrations TF-TP groups (F=2.15,P =0.11).The cell survival rate of blank control group,model group and 150 μmol/L TF-TP group was (100.0±0.00) %,(43.79±6.55) % and (63.45±3.57) %,and the survial rate was increased in the 150 μmol/L TF-TP group compared with the model group (P =0.00),and 150 μmol/L was detemined as a optimal concentration of TF-TP.A lot of shrinkage,deformation,suspension cells were exhibited under the optical microscope,and decrease of microvilli structure,rupture of mitochondrial cristae and vacuolar degeneration of the cells were found in the model group,and the damage of the cells were evidently lightened in the 150 μ mol/L TF-TP group.The apoptosis rate of the cells were (0.98 ±0.19)%,(9.98 ±0.82) % and (5.73 ±0.88) % in the blank group,model group and 150 μmol/L TF-TP group,respectively,with a significant difference among the groups (F =206.18,P =0.00),and the apoptosis rate of the cells in the 150 μmol/L TF-TP group was significantly lower than that in the model group (P<0.05).Compared with the blank control group,the relative expression of bax and TF was obviously increased and that of bcl-2 was decreased in the model group;while the expression of bax and TF was lower,and that of bcl-2 was higher in the 150 μmol/L TF-TP group compared with the model group (all at P < 0.05).Conclusions Pretreation of TF-TP can lessen cell apoptosis and increase cell survival rate and therefore plays a protective role to blue light-induced human RPE cells possibly by inhibiting bax/bcl-2 apoptotic pathways mediated by TF.

OBJECTIVETo establish the quantitative diagnostic criteria for cranio-orbito-zygomatic deformity (COZD).
METHODSComputer-assisted three-dimensional (3-D) CT measurement was performed in 30 cases with unilateral COZD. The differences of the measurement data between the affected and unaffected sides were analyzed. Then the patients were diagnosed and classified according to the affected bone, soft tissue and conjunctival sac. Based on the quantitative diagnosis, 8 patients underwent surgery to test the clinical practicability of the diagnostic criteria.
RESULTSThe quantitative diagnostic criteria for COZD could reflect the affected area and the corresponding severity of deformity. It helped to preoperative design and to predict movement of osteotomy segment and. the soft tissue volume needed for augmentation. Good postoperative results were achieved.
CONCLUSIONSThe quantitative diagnostic criteria for COZD can describe the affect area and severity of deformity in detail. It is very practical in the guidance of clinical treatment.
