Substantial evidence supports the relationship between chronic inflammation and cancer development. Numerous studies suggest that chronic inflammatory disease, such as periodontitis, contributes to head and neck squamous cell carcinoma development. Oral squamous cell carcinoma (OSCC) is the most common malignant tumor in the oral and maxillofacial regions. Porphyromonas gingivalis, one of the most important pathogens in association with periodontal disease, might have a potential correlation with OSCC. Along with the development of molecular biological techniques, the association between Porphyromonas gingivalis and OSCC has been greatly emphasized in recent years. This review summarizes the association between these variables and the potential mechanisms involved in such relationship.

5.Analysis of Anion Gap in Premature Suffered from Hyperbilirubinemia
Chinese Journal of Primary Medicine and Pharmacy 2012;(22):3379-3380
Objective To investigate the changes of the anion gap(AG)in the premature suffered from hyperbilirubinemia,to provide the basis for treatment.Methods The serum electrolyte,the renal function and the liver function in 94 premature babies suffered from hyperbilirubinemia were tested,and then calculated the value of AG,while the arterial blood gas analyses were done in 36 cases.Results 44 cases had high AG(46.81%),44 cases had normal AG(46.81%)and 6 cases had low AG(6.38%).The increase of AG was directly proportional to the concentration of Na+in blood,while was inversely proportion to the concentration of HCO3-.There was no close relationship between the AG and BUN,Scr in the serum.Conclusion The incidence rate of metabolic acidosis poisoning was high in premature suffered from hyperbilirubinemia with high AG,so the routine test of blood electrolyte,renal function and arterial blood gas should be done.Calculate the value of AG to guide the treatment,and to avoid correcting the acid by the alkali blindly.
6.Progress of signal transduction pathway of gastrin stimulating proliferation of colorectal carcinoma cells
Chinese Journal of Clinical Pharmacology and Therapeutics 2004;0(11):-
Recent studies indicate that there are expressions of gastrin and its receptors in the tissue and cell line of colorectal cancer .Gastrin stimulates the proliferation of colorectal carcinoma as well as inhibits the apoptosis of colorectal carcinoma so as to promote the growth and invasion of colorectal carcinoma via a series of signal transduction pathways induced by its specific receptors. To inhibit the abnormally active signal transduction pathways that stimulate the proliferation of colorectal carcinoma will provide a new effective measure for the prevention and management of colorectal carcinoma.But the accurate signal transductions are not clear and need further research.
7.Association between apoptosis induced in hepatoblastoma HepG2 cells by Cdk7 silencing and decreased pRb and Cdk2 phosphorylation
Chinese Pharmacological Bulletin 1987;0(01):-
Aim To evaluate the effect of Cdk7 silencing on the c ell cycle control, the phosphorylation level changes of Cdk2 and pRb in human he patoblastoma HepG2 cell culture in vitro, and to validate Cdk7 as a novel ta rget for anticancer therapeutics.Method Levels of Cdk7 and the phosphorylation levels of Cdk2 and pRb were measured by Western-blotting. DNA c ontents, cell cycle and apoptosis induced by Cdk7 silencing were analyzed by flo w cytometry and ultrastructural changes of cells were observed with transmission electron microscopy.Result The phosphorylation levels of pRb a nd Cdk2 and the levels of Cdk7 decreased in a concentration-dependent manner wh en the concentration was above 100 nmol?L -1. Indice of cells arrested in G 0/G 1 phases and apoptotic cells increased in a dosage-and time-dependent manner, the difference was significant between Cdk7 ASODN and the sense control (P
8.The influences of fenofibrate on levels of tumor necrosis factor-alpha in serum and adipocytes secretion of hypercholesterolemia rabbits
Chinese Pharmacological Bulletin 1987;0(02):-
Aim Background tumor necrosis factor-alpha (TNF-?) is produced by monocyte-macrophages and adipocytes. It may provide the link between inflammation and atherosclerosis. The aim of this study was to evaluate the effect of fenofibrate on serum TNF-? concentration and TNF-? secretion by adipocytes from hypercholesterolemia rabbits.Methods Ten male New Zealand white rabbits were fed with high-cholesterol diet for 8 weeks, and were randomly divided into two groups: ①high cholesterol group: maintained cholesterol diet for 4 wks; ② fenofibrate group: the same cholesterol diet supplemented with fenofibrate (30 mg?kg?d -1) for 4 weeks. And control group was fed with normal diet for 12 weeks. Subcutaneous adipose was collected for adipocytes culture. TNF-? concentrations in serum and adipocytes culture supernatant were measured by ELISA. Adipocytes were harvested for semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) studies. Results :Rabbits fed with high-cholesterol diet showed higher serum levels of total cholesterol, low density lipoprotein cholesterol than those fed with normal diet (P
9.The Comparison of Detecting RNFL using GDX and OCT
Journal of Medical Research 2006;0(12):-
Objective To estimate the general power of OCT and GDX in the detection of glaucoma on the item of retinal nerve fiber layer thickness.Methods 42 patients(80eyes)underwent OCT and GDX.To compare the results.Results There was significant difference between the two methods.but they had significant plus correlation.Conclusions The sensitivity and agreement of GDX in the examination of RNFL is quite good compared with OCT for the detection of glaucoma.
10.Clinical Study on Left Ventricular Diastolic Dysfunction Treated by Shuxuening Injection
Chinese Journal of Information on Traditional Chinese Medicine 2006;0(05):-
Objective To study the effect of Shuxuening injection on treatment of left ventricular diastolic dysfunction.Methods Ninety cases of left ventricular diastolic dysfunction were divided into control group and test group randomly,45 cases for each group.Both groups were treated with standard management and the treatment group was given Shuxuening injection(20 mL) additionally for 2 weeks.E/A ratio,peak E,peak A,LVEF were observed before and after treatment.Result The clinical symptoms of the two groups were all improved after treatment.The test group had a higher overall effective rate than the control group.The ventricular diastolic function paramenters(E/A ratio,peak E,peak A,LVEF) in the test group were much better than that in the control group.Conclusion Shuxuening injection can improve the clinical symptoms and signs of left ventricular diastolic dysfunction.
