1.Regulation mechanism of unfolded protein response: progress and clinical prospect
Academic Journal of Second Military Medical University 1981;0(03):-
Unfolded protein response(UPR) is a protective response in cell endoplasmic reticulum(ER) under stress condition.Three ER transmembrane proteins,IRE1,PERK,and ATF6,coordinately regulate the UPR function in mammalian cells through their signaling pathways.In addition,some proteins and transcription factors during the UPR can provide negative and positive feedback loops to maintain the normal function of ER.UPR can trigger cell death or apoptosis and eventually cause related diseases if the ER stress persists.Several key mediators of UPR are candidates for therapeutic targets in many studies.Up to now progress has been made in the area,which provides new ideas for clinical practice and holds a great potential for future application.

AIM: In order to observe the curative effect of Fugan Tablet on chronic hepatitis B and hepatic fibrosis,we held clinical observation of 120 cases of chronic hepatitis B and hepatic fibrosis. METHODS: 120 cases of chronic hepatitis B and hepatic fibrosis were divided into curative group with Fugan Tablet and control group with Hepatic Ling Injection,and the change of symptom,hepatic function,iconography index,hepatic fibrosis in serum and the hepatic histology were observed before and after the treatment,then the curative result of the two groups was compared. RESULTS: The total effective percentage of curative group was 88.33%,and the total effective percentage of control group was 68.33%.Comparing the two groups,the difference was obvious(P
3.Significance of the detection of spontaneous apoptosis and the expression of p27kip1 in transitional cell carcinoma of bladder
Cancer Research and Clinic 2000;0(06):-
Objective To investigate the clinical significance of the rate of spontaneous apoptosis and the expression of p27kip1 in transitional cell carcinoma of bladder (BTCC). Methods Immunohistochemical analysis of p27kip1 was performed on paraffin embedded tissue sections in 50 cases of BTCC, by immunohistochemical method S-P. The terminal deoxynucleotidyl transferase- mediated dUTP- biotin nick end labeling (TUNEL) was used to examine the level of apoptotic cells in 50 cases of BTCC. Results In BTCC, the spontaneous apoptosis index AI was (3.0?1.5)%, the positive rate of p27kip1 was 58.0 %(29/50). Both of them decreased with the escalation of the clinicopathologic grade and stage. The positive expression of p27kip1 protein were significantly associated with higher spontaneous apoptosis (P

Medical integration is an inevitable trend of medical development and medical educa-tion reform nowadays. Under the guidance of integration,medical colleges at home and abroad develop a series of exploration and practice of medical education reform. According to difficulties and problems of medical education reform,this article put forward:changing ideas to adapt to the transformation of medi-cal model,combining medical education reform and new medical reform,playing the main role of educa-tion administration department in the reform of medical course system,strengthening multi-dimensional integration of medical science.

Many genetic events have been described to be involved in the development of tumor,but a lot of recent researches proved that epigenic events also played an important role in it.DNA methylation is one of the common modification of epigenic events,the binding of methyl-CpG binding domain proteins has been shown to lead to transcriptional repression of many tumor repressor genes.

Objective: To develop and optimize a self-microemulsifying drug delivery system (SMEDDS) formula for improving the dissolution of atorvastatin calcium.Methods: Solubility and pseudo-ternary phase diagram were used to select the suitable type and amount range of oil phase, surfactant and co-surfactant.D-optimal mixture design was used to optimize the formula of atorvastatin calcium SMEDDS.The morphology, particle size distribution and zeta potential of the microemulsion were determined by a dilution method.The in vitro drug release profiles of the marketed atorvastatin calcium tablets and the self-made SMEDDS were compared.Results: The formula of atorvastatin calcium SMEDDS was as follows: Capmul MCM as the oil phase, Labrasol as the surfactant and Transcutol P as the co-surfactant with the optimal weight ratio of 13.0∶43.5∶43.5.The self-made SMEDDS was a clear and transparent microemulsion solution with homogeneous small spheres as seen under a transmission electron microscope.The particle size, PdI and zeta potential of the self-made SMEDDS was (34.2±13.6) nm, (0.169±0.04) and (-21.1±1.3) mV, respectively.The in vitro release profile indicated that the accumulated release of the self-made SNEDDS reached up to nearly 100% in 45 min.Conclusion: The optimal formula of atorvastatin calcium SMEDDS optimized by D-optimal mixture design can improve the drug dissolution rate effectively.
