Chinese Pharmacological Bulletin 2003;0(11):-
Aim To explore the mechanisms of Curcumin which plays a role of protecting cells through regulating the activity of GSK-3?.Methods Plasmid APPswe and BACE1-mychis were transiently co-transfected into SHSY5Y cells.The cells were treated with Curcumin and then were collected to determine the mRNA and protein levels of GSK-3?,?-catenin and CyclinD1 by RT-PCR and Western blot. Immuno-fluoresecnt staining was used to detect the location and expression of ?-catenin and GSK-3?, and ELISA was for the generation of A?.Results RT-PCR and Western blot results showed that in the cells, Curcumin inhibited the expression of GSK-3? mRNA and protein, and promoted the expression of GSK-3?-Ser9 protein (P

China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(03):-
On the basis of the origin,development and modern research of xuanfu theory,a new view of nose xuanfu theory is put forward,in wich,the mechanism of chronic sinusitis is blodkade of two orrifices and interties of two toxins.Additionally,on the basis of inducing resuscitation and opening xuanfu,a new treatment principle of dredging sinus orrifi ces,opening xuanfu,removing two toxins and strengthening vital qi are put forward,too.From modern medical point,nose xuanfu is corresponding to intercellular space of nasal mucous membrane,all kinds of ion channels and nasal tissue microcirculation.Nose xuanfu is qi-fluid circulation channel in internal and external environmental material information communication of nasal tissue.Nose xuanfu normal opening-and-closing function keeps normal physiological function of nasal cavity.Nose xuanfu theory provides one new way in rhinology with TCM.
4.Preparation and evaluation of self-microemulsifying drug delivery systems containing tanshinone Ⅱ_A
Chinese Traditional and Herbal Drugs 1994;0(04):-
Objective To optimize the formulation of self-microemulsifying drug delivery systems containing tanshinone ⅡA(tanshinone ⅡA-SMEDDS) and assess the quality of tanshinone ⅡA-SMEDDS. Methods Pseudoternary phase diagrams were used to choose the oil,emulsifier,co-emulsifier,and their proportion in the formulation on the basis of the ability to form emulsions and regions. Then the self-emulsifying time,droplet and morphology,size distribution,?-potential,stability,and other aspects of the quality were evaluated. Results The formulation of tanshinone ⅡA-SMEDDS was as follows:ethyl oleate-Labrasol-PEG 400=10%:45%:45%,drug loading ratio was 2.25 mg/g. The self-microemulsifying time of tanshinone ⅡA-SMEDDS in 0.1 mol/L hydrochloric acid solution was less than 1 min,the emulsion drops were spherical shape with average particle size of (84.9?2.1) nm and the average ?-potential (-24.0?1.15) mV (n=3). So tanshinone ⅡA-SMEDDS was stable. Conclusion In this paper,the tanshinone ⅡA-SMEDDS has a good self-emulsifying performance. It is expected to further stabilize the preparation of tanshinone ⅡA self-microemulsifying agents.
5.Advances of the Relationship Between Tumor Suppressor Gene DPC4 and Pancreatic Carcinoma
Chinese Journal of Bases and Clinics in General Surgery 2003;0(04):-
Objective To investigate the relationship between tumor suppressor gene DPC4 and the development and prognosis of pancreatic carcinoma. Methods Relevant literatures of recent years were reviewed. Results DPC4 was located on chromosome 18. Its product was Smad 4 protein. Smad 4 protein was the central component of the transforming growth factor-beta signaling pathway, and all the biological effect was the results of interaction of Smad 4 and different Smads. The gene was deleted or inactive in about 50% of pancreatic carcinomas. The deletion of DPC4 had a great relation to the development and prognosis of pancreatic carcinoma. Conclusion The alteration of tumor suppressor gene DPC4 is connected with the development and prognosis of pancreatic carcinoma. However, this research should be further studied.
6.Determination of Amphotericin B in Vaginal Effervescent Tablets by RP-HPLC
China Pharmacy 2001;0(07):-
OBJECTIVE: To establish a RP-HPLC method for the content determination of amphotericin B in amphotericin B vaginal effervescent tablets.METHODS: HPLC was performed on Kromasil C18 column with the mobile phase consisted of 0.01 mol ?L-1 potassium dihydrogen-acetonitrile(66∶34) at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 408 nm;the sample size was 10 ?L,and the column temperature was set at room temperature.RESULTS: The linearity of amphotericin B was good in the range of 0.404~3.636 ?g(r=0.999 4) and the average recovery rate was 99.39%(RSD=0.22%,n=6).CONCLUSIONS: The method is simple,accurate,feasible,and it can be used for the determination of this tablets.
7.Role of gap junction in cognitive function
Chinese Journal of Pathophysiology 2000;0(07):-
Gap junction is one kind of synapse coexisting with chemical synapse in the nervous system. Nowadays with the development of electrophysiological technique,more research began to focus on the role of gap junction in the neural network,especially in the cognitive function. Gap junction collaborates with chemical synapses to induce the neural network activities related to memory and perception,such as gamma and ripple oscillation,which is regarded as the mechanism of the role of gap junction in cognitive function. This review introduces the structure of gap junction,distribution and expression of different kinds of connexins in central nervous system,which are the basic element of gap junction. Furthermore,this review discusses the role of gap junction in cognition related network oscillations and activity-dependent plasticity of gap junction.
