Objective: To research the activity of antibacterial proteins isolated from Musca domestica during larvae-pupae metamorphosis. Methods: The 5-day-old larvae of Musca domestica were injured with a needle. 24h later, the larvae which had changed into pupae were selected. The antibacterial protein was isolated by a four-step protocol including grinding, heating, CM-sepharose F. F. cationexchange chromatography and another CM-sepharose F. F. chromatography. Antibacterial activities of samples were tested by an ultrasensitive radial diffusion assay using Staphylococcus aureus as the indicator organism. The molecular weight of the isolated protein was determined by SDS-PAGE.Results: The molecular weight of this isolated protein was 43kDa, and its antibacterial activity was strong. Conclusions: A kind of protein with strong antibacterial activity can be produced in the Musca domestica during larvae-pupae metamorphosis.

Objective:This study aims to investigate the protein expression of coxsackie-virus and adenovirus receptor (CAR) in partial subtypes of pulmonary adeno-carcinoma, as well as its expression with clinico-pathological factors and prognosis. Methods:CAR expression was immunohistochemically assessed in 137 cases of lung cancer with bronchiole-alveolar carcinoma (PWBF) fea-tures, and analyzed in relation to various clinico-pathological parameters. All data were analyzed using SPSS statistics software, and Ka-plan-Meier survival curves were constructed. A Log-rank test was also conducted. Results: The CAR positive rates in PWBF, other types of lung cancer, and normal lung tissue were 71.5%, 50.0%, and 13.3%, respectively. The difference was statistically significant (P<0.05). In addition, a statistically significant difference was observed between the positive expression of CAR and other clini-co-pathologic parameters, such as pathological type and histological differentiation. No statistical significance was observed in other pa-rameters, such as gender, age, smoking, and tumor diameter. Patients with CAR positivity were characterized by longer survival times than the others;however, this difference did not reach statistical significance. Conclusion:CAR is related to the occurrence and devel-opment of lung cancer, especially PWBF. The higher expression of CAR in PWBF for gene therapy with adenovirus vectors opened a broader space. The conspicuous regulation of CAR may be reliable evidence and may bright future for the gene therapy of other types of lung cancer.

AIM: To investigate the effects of proteasome inhibitor Z-LLL-CHO(MG132) on human osteosarcoma cell line MG-63 and its possibly mechanism.METHODS: After treated with different concentration of MG132,the morphological change,ultrastructral morphology,cell viability,cell apoptosis,gene transcription and protein expression in MG-63 cells were accessed by fluorescence microscope,electron microscope,MTT assay,agrose gel electrophoresis,FCM,RT-PCR and Western blotting.RESULTS: Proteasome inhibitor MG132 was an effective inducer of apoptosis in human osteosarcoma MG-63 cells.Not only apoptotic changes,but also cell arrest at G2-M-phase,the accumulation of p27kip1,the accumulation of activated caspase-8 and increased ratio of Bax∶Bcl-2 were observed.However,to normal human diploid fibroblast cells,MG132 did not show apoptosis-inducing effect.CONCLUSION: Apoptosis induced by MG132 may be caspase-8,p27kip1and bcl-2-related.

Objective:To find the reasons for the low dissolution of clarithromycin tablets and study the interference from filter film adsorption at various time points to explore the appropriate processing approach for dissolution solution of clarithromycin tablets. Meth-ods:Clarithromycin tablets from two different manufacturers were used. The dissolution solution was prepared according to Japanese Orange Book. The dissolution was determined after different processing and the adsorption rate of the filter film was calculated. Re-sults:Totally 14 kinds of filter films were tested with different adsorption for clarithromycin, and the adsorption rate of some kinds of filter films exceeded the prescribed limit. Conclusion:The absorption rate of filter films for clarithromycin can be decreased by boiling the films and using American membranes. The interference from filter film adsorption can be reduced and inhibited by rejecting the first filtrate above 5ml or centrifuging dissolution solution.
