Objective: To study the effect of ?- carotene(?-C) on lipid peroxidation and RBC-membrane fluidity of rats inflicted with alloxan. Methods: Forty-four 2mo-old Wistar rats were randomly divided into 4 groups and fed with basal diet (group A and B), basal diet + vitamin E (200 mg/kg) (C) and basal diet+? carotene (200 mg/kg) (D) for 4 w respectively. Then, alloxon (3%) was injected intraperitoneally except group A, which was injected with normal saline. After 48 h the rats were killed and a series of indices were examined. Results: After injected with alloxan, Na +,K +-ATPase and GSH-Px activity, RBC-membrane fluidity in rats fed with diets C,D were markedly increased while MDA levels were decreased. Conclusion: ?-C and V E can decrease lipid peroxidation and increase the stability of RBC-membrane in rats inflicted with alloxan.

Objective To evaluate the clinical characteristics,pathology,treatment and prognosis of gastrointestinal stromal tumors.Methods A retrospective analysis was made on clinical data of 469 patients with gastrointestinal stromal tumors (GIST) admitted between January 2010 and August 2016.Results There were 231 males and 238 females,the median age was 57 years old.The tumor was located in the esophagus in 6 cases (1.3％),in the stomach in 295 cases (62.9％),in the duodenum in 23 cases (4.9％),in the small intestine in 69 cases(14.7％),in the colorectum in 26 cases (5.5％).There were altogether 50 cases (10.6％) in this group with a final diagnosis of extra-gastrointestinal stromal tumors.Tumor invasion depth,risk of ulcer caused bleeding and NIH classification varied with its locations (all P ＜ 0.05).Conclusions The clinical characteristics of gastrointestinal stromal tumors can be used to preliminarily predict its malignant degree.Surgical resection is the treatment of choice,and postoperative recurrence or metastases of gastrointestinal stromal tumors can be treated by imatinib.

Objective To investigate the expression and possible function of tumor susceptibility gene 101 (TSG101) in multidrug-resistant cell lines of gastric cancer.Methods The expression of TSG101 was examined in gastric cancer cell line SGC7901 and its vincristine(VCR)-resistant subline SGC7901/VCR with semi -quantitative RT-PCR and Western blot. TSG101 eukaryotic expression vector was transfected into SGC7901 cells by lipofectamine TM 2000. The expression levels of TSG101 in SGC7901 and the transfectants were detected with Western blot. Fluorescence-activated cell sorting was applied to examine the cell cycle alteration and the intracellular mean fluorescence intensity of adriamycin (ADR). Growth curve and drug sensitivity of cells to VCR and ADR were analyzed by MTT assay.Results TSG101 was highly expressed in VCR resistant gastric cancer cells. The expression of TSG101 in TSG101 transfectants was up-regulated compared with that in SGC7901 transfected with empty vector or in SGC7901 cells. TSG101 transfectants were accumulated in S phase, with a concomitant decrease of cell population in G 1 phase. MTT assay showed that TSG101 transfectants proliferated rapidly and were more resistant to VCR and ADR than control cells. Conclusions The over-expression of TSG101 could promote the multidrug resistance phenotype of sGC7901 cells. TSG101 may play a certain role in multidrug resistance of gastric cancer.

Objective To research the best plant treatment formulation of flos carthami,aloe vera and potato on mannitol-induced phlebitis in rabbits. Methods Using mannitol-induced phlebitis model in rabbits,the experimental groups contained simple dosage and mixture of three plants,the control groups were blank control group and 95％ ethanol group.The curative effects of phlebitis treatment were observed between groups. Results The curative effect of aloe vera and potato mixture group was the best compared with other groups. Conclusions All of the three plants have good curative effects on mannitol-induced phlebitis,and the best plant treatment formulation was aloevera and potato mix-using.

Aim To evaluate the reversal effect of 2-deoxy-D-glucose ( 2-DG ) on multidrug resistance ( MDR) by observing the uptake change of 99m Tc-MIBI in HNE-1/DDP cells, and to explore its mechanism. Methods The uptake of 99m Tc-MIBI in HNE-1/DDP cells under different concentrations of 2-DG was detec-ted by γ-counter, and the clearance rates of 99m Tc-MI-BI in HNE-1 cells and HNE-1/DDP cells after treated with 2-DG (10 mmol·L-1 ) were compared. The con-tent of ATP in HNE-1/DDP cells was detected after treated with 2-DG. P-glycoprotein ( P-gp ) and multi-drug resistance-associated proteins ( MRP ) expression were measured by Western blot. Apoptotic HNE-1/DDP cells treated with DDP alone or combined with 2-DG (10 mmol·L-1 ) were detected by propidium io-dide ( PI ) staining. Results The clearance rate of 99m Tc-MIBI in HNE-1/DDP cells was 54. 8%, which was significantly higher than that ( - 41. 3%) in HNE-1 cells (P<0. 01). The clearance rate of 99mTc-MIBI in HNE-1/DDP cells was -203. 7% after treat-ment with 2-DG ( 10 mmol · L-1 ) , which could be significantly reduced compared with the control group ( P<0. 01 ) . The level of ATP was 55 . 69% compared with the negative control group and the expression of P-gp and MRP protein decreased dramatically in HNE-1/DDP. With the combination of 2-DG and DDP, the ap-optotic rate of HNE-1/DDP cells reached 49 . 4%which was significantly higher than DDP treated group (22. 5%) . Conclusion Multidrug resistance and the reversal effect of 2-DG on multidrug resistance could be evaluated effectively by detecting the uptake change of 99m Tc-MIBI in HNE-1/DDP cells. The mechanism may be related with the inhibition of ATP level and the re-duced expression of P-gp and MRP protein in cancer cells.

Aim To investigate the influence of iridosides of cornus officinalis(ICO) on morphology, cell cycle and oxidative stress of glomerular mesangial cells(GMC) cultured with advanced glycation end products(AGEs). Methods GMC were incubated in culture medium containing AGEs in the presence of ICO and aminoguanidin for 48 hours. At the same time, the control and model groups were added. Then the cultured GMC were stained by mixed fluorescence liquid and observed under fluorescence microscope. Cell cycle of GMC were analyzed using flowcytometry. The content of MDA, activity of SOD and GSH-Px in GMC supernatant were measured. The level of ROS was detected using flowcytometry. Result Morphology analysis showed that the morphology and structure of normal GMC were normal. The structure of most cells in AGEs were unclear, cell counts increased largely and they grow intensively. Cell cycle analysis showed that cell percentage of S phase increased and G_0/G_1 reduced. The level of ROS, MDA remarkably increased, and SOD, GSH-Px activity reduced. When the ICO were added, cell morphology tended to be basically normal and cell counts decreased, the percentale of S phase also decreased. The level of ROS, MDA and the SOD, GSH-Px activity restored in comparison with the model groups. Conclusion ICO can prevent the cultured GMC from lesion caused by AGEs. ICO may protect GMC from AGES to retard the progression of diabetic nepropathy by partially inhibiting the occurrence of oxidative stress.

Ulcerative colitis( UC)is a disease difficult to cure and easy to relapse. Although the pathogenic and recurrent factors for UC are not clear,dietary factors are thought to be associated with both of them and becoming the hot topic of UC-related studies. Traditionally,dietary fiber is considered beneficial to UC,however,some of the latest overseas studies raised doubts about it. In this article,the dietary fiber and its role in UC were reviewed.

Objective To study the antithrombotic effect of polysaccharide extracted from Thallus Laminariae(PTP) on rats with endothelial injury.Methods Two kinds of endothelial injured rat models were established by injecting adrenaline and endotoxin.The wet weight of thrombus was evaluated by artery-vein loop method,the starting time of thrombus formation and the speed of blood flow were observed by mesentery microcirculation.Results In adrenaline-induced injury rats,the wet weight of thrombus was obviously decreased in high-dose PTP group and aspirin group compared with the model group.In endotoxin-induced injury rats,the starting time of thrombus formation was longer and the one-hour blood flow speed was faster in all TP groups and aspirin group than those in the model group.Conclusion PTP exerts the antithrombotic effect on rats with endothelial injury.
