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.

Objective To study the effect of IFN-αcombined with ATRA in liver cancer therapy in perioperative phase of inter-vention .Methods An animal model of liver cancer CBRH7919 was established by implanting 28 Wistar rats with tumor tissue .The hepatic artery was tied off in one month after formation of tumor .All the rats were randomly divided into the experimental group (14 cases) and the control group(14 cases) .The control group accepted peritoneal injection with normal saline while the experimen-tal group accepted IFN-αcombined with ATRA .10 days later ,all the rats were sacrificed .And the level of expression of VEGF ,bF-GF ,mirovessel density ,and apoptotic index of tumor cells were measured .Results Serum VEGF level ,MVD and apoptotic index of tumor cells of the experimental group were statistically lower than that of the control group [(91 .8 ± 12 .7) pg/mL ,(115 .7 ± 11 .8)/HP ,(12 .29 ± 4 .53)% vs .(67 .4 ± 18 .3)pg/mL ,(65 .3 ± 7 .2)/HP ,(3 .81 ± 1 .52)% ,t=4 .099、13 .642、6 .640 ,P<0 .05)] , results of RT-PCR and immunohistochemistry detection both showed that the levels of expression of VEGF and bFGF of the exper-imental group was lower than that of the control group .Conclusion IFN-αcombined with ATRA in liver cancer therapy in periop-erative phase of intervention could suppress the generation of neoplastic vascular and improve the effect of the intervention .So it is worth promoting .

With the development of modem technology,more and more plastic products are widely used in various fields,while bringing significant convenience to the society,it also leads to more and more environmental estrogen.The influence of plasticizer is increasing,especially on the development of children.Extensive contacting with plasticizer is considered to be closely related with gonadal digenesis,obesity and other problems in children.This review focuses on the latest research results about the basic and clinical experiments of Di (2-ethylhexyl) phthalate (DEHP),which illuminate the effects of DEHP on children's growth and metabolism,and lay foundations for rational clinical intervention and scientific plasticizer's application.

Because of the relationship between the quality and the processing technology of Chinese herbal pieces was very close, we proposed concerning the problems of Chinese herbal pieces characters and processing experi-ence. Then, we made use of intelligent sensory technique to objectively express the characters of Chinese Herbal pieces, and explored to set the methods and models about evaluating the quality of Chinese herbal pieces of appear-ance characters and internal quality. To realize the expression of experience terms such as huoli and huohou in the process of Chinese herbal pieces objectively, we adopted on-line infrared temperature measurement and biologi-cal evaluation technologies, and established new technologies and methods of Chinese herbal pieces process quality control in the process.We established a workable monitoring technology, which could not only achieve the controlla-bility and stability of processing quality, also ensured the safety and effectiveness of Chinese herbal pieces.

Clinicians should assume the responsibility of nutritional therapy for satisfactory outcomes. They should master knowledge on nutritional metabolism, and participate in the administration of nutritional support. Clinicians should be acquainted with new concepts and standardized techniques in this field, such as different requirement of energy, understanding of early nutritional support, and optimal regimens of enteral or parenteral nutrition.

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.

Objective To study the effects of combined telmisartan and ramiprll on heart function and renin - angiotensin - aldoste-tone system and ventricle remodeling and brain natriuretie peptide in patients with chronic heart failure (CHF). Methods 100 patientswith chronic heart failure were randomly divided into three groups: telmisartan group (A group, treated with telmisartan 80mg once daily, n =33), ramipril group (B group treated with ramipril 5mg once daily, n =33) and telmisartan plus ramipril group (treated with telmis-artan 40mg plus ramipril 2.5mg once daily, n = 34). Left ventricular end - diastolic dimensions (LVEDD) and left ventricular ejection fraction (LVEF) were assessed, and plasma renin activity (Ren) , angiotensinIl (Angll), aldosterone (Aid) and brain natriuretic pep-tide (BNP) were measured before and after therphy. Results After 6 months of treatment, LVEDD and LVEF were improved in all groups(P < 0.01). All changs were significant in C group than those in A group or B group(P < 0.01). The concentration of Ren were in-creased in all groups(P <0.01). The concentration of Angll was increased in A group and decreased in B group(P <0.01)while there was no difference at pre or post treatment in C group (P > 0.01). The concentration of Ald and BNP was decreased in all groups (P < 0.01). Ald and BNP were decreased more significantly in C group than those in A group or B group. Conclusion Combination of low dose of telmisartan and ramipril therapy has more benificial clinical features than telmisartan or ramipril alone in patients with CHF.
