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.

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 summary clinical experience of laparoscopic treatment of cholecystitis with cholecystolithiasis complicated,in order to provide reference for clinical difficult laparosco-pic resection of gallbladder.Methods Reviewing the operation treatment of laparoscopic cholecystectomy on 94 complex cases of resection during January 2008 to December 2014.Results The 94 patients included 17 cases with severe adhesion around gallbladder,9 cases with gallbladder atrophy,39 cases with gallbladder ampulla and cystic duct stone incarceration,11 cases with acute gangrenous cholecystitis with gallbladder stones,14 cases with gallbladder triangle anatomy is not clearing and 19 cases with gallbladder stones with schistosomial cirrhosis or liver volume variation.Some cases were with the two or more kinds gallbladder stone.There were 91 cases with successful implementation of the laparoscopic cholecystectomy,4 of 91 cases were treated with subtotal cholecystectomy,and 3 cases were converted to open cholecystectomy.There were no cases with serious complications or even deaths.Conclusion Regarding of the complex gallbladder stones appear different situation in operation,we can complete the operation by using different operation method and treatment method in laparoscopic.

Objective To determine the role of SCN1A gene variation in the development of familial febrile seizures (FS).Methods Clinical data were collected from 8 familial FS pedigrees, and peripheral venous blood samples were collected from the probands and other available family members. All 26 coding exons and exon-intron boundaries at least 50 bases of the human SCN1A gene were amplifled by polymerase chain reaction, the products were subsequently sequenced. To novo variation, other family members were screened for the corresponding exons. Two hundred age-matched healthy children were served as normal controls. ResultsA total of 33 variations in the SCN1A gene were identifled in these families. Of these variations, one was a missense mutation; the remaining 32 variations were previously submitted as single nucleotide polymorphisms (SNPs). A c.2650G>A heterozygous missense mutation in exon 15 of the SCN1A gene found in the proband of family 4 was inherited from his father who had seizures with fever in early childhood. The c.2650G>A mutation was absent in the 400 alleles of normal controls. To the best of our knowledge, the SCN1A c.2650G>A mutation has neither been reported in the NCBI SNP database nor in the literature to date. The c.2650G>A mutation changes a glycine at amino acid 884 in the SCN1A protein to a serine (p.Gly884Ser). Protein sequence analysis showed that the p.Gly884Ser is located at a highly conserved region between the 4th and 5th transmembrane segment of the homologous domain Ⅱ of voltage-gated sodium channel 1 subunit (DIIS4-S5). ConclusionsThe pathogenesis of familial febrile seizures was related to the SCN1A variation, the mutation outside the region of the voltage sensor (S4) and ion channel pore (S5-S6) of the voltage gated sodium channelα-subunit may be an important factor to cause mild phenotype epilepsy syndrome.

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 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.

Objective To evaluate endothelium dysfunction of arteries for early preventing atherosis. Methods A new portable device for detection of endothelium dysfunction by photoplethysmographic method was designed, which depended on the principle of reactive hyperaemia. Results Experiments between hypertensive and normotensive showed that different degree endothelium dysfunction had emerged among hypertensive. Conclusion The proposed device has potential benefit to research, diagnosis and therapy evaluation for subclinic arterial disease.
