1.The role of cyclooxygenase-2 in the growth and development of the endometrial lesions
Chinese Journal of Primary Medicine and Pharmacy 2008;15(10):1658-1659
Objective To study the role of cyclcoxygenase-2 in the growth and development of the endome-trial lesions. Methods The expression of cycloogxygenase-2 (COX-2) were tested by immunohistocbemistry. Compar-ison of endometrial cancer COX-2 expression was made within each group at different stages,for different pathological classification. Another groups comparison of COX-2 expression was made. Results ( 1 ) COX-2 in endometrial cancer in the different expression of other differences and differences were significant ( P<0.05 ). Ⅲ mainly for the period between the stage and the other had a significant difference( P<0.05 ). (2) COX-2 in endometrial cancer,hyperplasia and normal expression of the differences between endometriosis, the difference was significant ( P<0.05 ). (3)COX-2 in endometrium cancer different pathology graduation difference:G1(high idiophase) < G2(idiophase) < G3(low id-iophase), but does not have the difference after the comparison in statistics ( P>0.05 ). (4) The expression of COX-2 in simple hyperplasia and complex hyperplasia was statistically significant different ( P<0.05 ). Conclusion That COX-2 in the development of endometrial lesions play an important role, it could be inferred of COX-2 inhibitors for endometrial cancer treatment or treatment of postoperative the timing of the loss surgery patients is feasible.

Journal of Medical Research 2006;0(04):-
Objective To study the relationship between survival rate and pathogen,subtype,stage,delivered methods of 55 patients with severe hepatitis during late period of pregnancy.Methods Clinical data of 55 cases with severe hepatitis during late period of pregnancy was analyzed retrospectively.Results The incidence of hepatitis B was highest in patients with severe hepatitis during late period of pregnancy (84.5%).In subtypes,the incidence rates of chronic severe hepatitis,acute severe hepatitis and subacute severe hepatitis were 83.6%,5.5%,10.9% respectively(P
3.Clinical analysis of Infections Complication Patients with Severe Hepatitis
Journal of Medical Research 2006;0(06):-
Objective To investigate the infection type,clinical features and prognosis in the infections complication patients with severe hepatitis.Methods 72 severe hepatitis patients with infections complication were analyzed retrospectively.Results The infection occurrence rate was 62.5% in the 72 severe hepatitis patients.Mortality rate was 75.56% in the patients with infections complication,and it was significantly higher than those without infections complication(29.63%).The mortality rate was 72.5% in the patients with multiple organ infections.The different bacterium infection could lead to different mortality rate,K.peneumoniae(69.89%),E.coli(58.12%),Staphylococcus aureaus(55.56%),Staphylococcus epidermidis(59.90%).The mortality rate was higher in the patients with lower sera albumin and higher serum bilirubin level.Conclusions The patients with severe hepatitis have bad outcome with infections complication.The prognosis is correlated with the dysfunction severity of liver and pathogenic bacteria.
4.On the Traditional Medical Treasures of Zhou Yi(also known as "the book of changes") and Qian Jin(Precious Essential Formulary,PEF)
Chinese Medical Ethics 1995;0(02):-
The traditional medical treasures of zhouyi and qianjin have much in common in the aspects of logic approach,recognition characteristics,values conception,theory construction,and category system,which demonstrate that the two doctrines are closely related both geographically and historically. Bearing the same cultural genes and value orientation,sharing similar constructions of logic approaches and recognition characteristics,the two doctrines contain a great deal of wisdom in recognition and practice.
5.Role of TRAF2 in AP-1 signaling pathway of human B cells
Basic & Clinical Medicine 2006;0(05):-
Objective To investigate the role of TRAF2 in AP-1 signaling pathway of human B cells.Methods Human Ramos B cells were transfected with plasmids expressing YFP fusion wild type TRAF2(YFP-WT-TRAF2) or YFP fusion dominant-negative TRAF2(DN-TRAF2),or transfected with shRNA-TRAF2 and control shRNA plasmid.After incubation overnight,cells were either sorted with flowcytometry or screened by antibiotics G418.Activation of AP-1 pathway,including phosphorylation of ERK,JNK and P38,as well as nuclear translocation of AP-1 subunits were detected by western blot and ELISA.Results Overexpression of WT-TRAF2 selectively induced activition of MAPK by phosphorylation of ERK and P38,and further induced nuclear translocation of C-FOS.Moreover,both overexpression of DN-TRAF2 and transfection of shRNA-TRAF2 inhibited phosphorylation of ERK and P38,and nuclear translocation of C-FOS.Conclusion TRAF2 selectively activates some kinases in CD40 mediated AP-1 signaling pathway,and plays an important role in AP-1 activation.
6.Effects of isoflurane on neuronal apoptosis In aged rats
Chinese Journal of Anesthesiology 2009;29(7):610-612
Objective To investigate the effects of different concentrations of isoflurane on neuronal apoptosis in hippocampus and cerebral cortex in the aged rats. Methods Ninety female pathogen-free SD rats 22-24 months old weighing 497-593 g were randomly divided into 3 groups: group Ⅰ oxygen group inhaled air enriched with 40% O2,groupⅡ and Ⅲ were anesthetized with 1.2% and 1.8% isoflurane for 3 h respectively. Morris water maze was used to assess the cognitive function. The animals were killed at 24 and 72 h and on the 7th day after emergence from anesthesia and their brains were removed. Neuronal apoptosis in hippocampus and cerebral cortex was detected by TUNEL. Results The average escape latency was significantly longer on the 2nd and 3rd day after isoflurane anesthesia in isoflurane group than in oxygen group (P < 0.05 ). The neuronal apoptesis rate was significantly higher in the 2 isoflurane group than in oxygen group (P < 0.05 or 0.01 ). Conclusion Isoflurane anesthesia can result in transient cognitive dysfunction, and the mechanism may be involved in apoptosis in cerebral cortex in the aged rats.

China Journal of Chinese Materia Medica 2015;40(2):264-268
Ten compounds, including five steroidal saponins and five flavonol glycosides, were isolated from the whole plant of Solanum coagulans by means of column chromatographies over silica gel, ODS, Sephadex LH-20, and preparative HPLC. Based on analysis of MS and NMR spectroscopic data, their structures were established as anguiviosides XV (1), smilaxchinoside A (2), methylprotodioscin (3), protodioscin (4), solamargine (5), 3', 4', 5-trihydroxy-7-methoxy-6-C-β-D-glucopyranoside (6), brainoside B (7), camsibriside A (8), kampferol 3-O-(2"-β-D-galactopyranosyl)-β-D-glucopyranoside (9), and quercetin-3-O-(2"-β-D-galactopyranosyl)-β-D-glucopyranoside (10). All the compounds were first isolated from this plant. In the in vitro assays, compounds 4 and 5 showed cytotoxic activity against SMCC-7721 and NCI-H460.

10.Classification and clinical significance of retinal hemorrhage
Ophthalmology in China 2009;18(4):221-224
Retinal hemorrhage can be divided into intravitreal, subhyaloid, subinner limiting membrane, superficial retinal, deep retinal, subretinal and subpigment epithelial hemorrhage. Each of these hemorrhages has a characteristic and recognizable appearance. Comprehending the classification and characteristic of retinal hemorrhage has important value in diagnosis, differential diagnosis and guideline for treatment.(Ophthalmol CHN, 2009, 18: 221-224)
