BACKGROUND:The incidence rate of cervical abnormalities of the patients with skeletal class Ⅱ and normal occlusion has been studied abroad, but the researches on the incidence of cervical abnormalities in different malocclusion patients is rare at home. OBJECTIVE:To observe the imaging of patients with cervical abnormalities and to statistics the incidence of cervical abnormalities in different malocclusion patients through analyzing the lateral cephalogram of different malocclusion patients. METHODS:Skeletal class Ⅱ group was consisted of 93 patients, 41 male (aged 18-40 years) and 52 female (aged 22-35 years), with the A point-nasion-B point angle>5°. Class Ⅰ group was consisted of 45 patients, 31 female (aged 20-36 years) and 14 male (aged 17-38 years), with the 1°

Objective:To investigate the relationship between changes of the concentration of IL -12,IL-4,IFN-γwithin cervical local immune microenvironment and cervix infected with HPV 16,58,to understand the prevalence of physical status of HPV 16/58 DNA into the host genome in cervical lesions of different grades and to detect the relation between the integrated state of virus and the progress of cervical lesions.Methods: Detecting 89 cases of cervicovaginal lavage fluid and 140 cytological specimens of the cervix which from patients having had HPV-DNA genotyping assays and coming from the Affiliated Tumor Hospital of Guangxi Medical University from 2012.8 to 2013.5.89 cases of cervicovaginal lavage fluid were divided into 58 cases of HPV16 (+) and 31 cases of HPV58(+).Cytokines IL-12, IL-4, IFN-γin the cervical microenvironment were detected by ELISA assay.140 cases of cervical exfoliated cells were divided into 106 cases of HPV16(+) and 34 cases of HPV58(+).Using qRT-PCR to quantify the copy number of E2 and E6 genes and analyze the physical status of HPV 16/58 DNA according to E2/E6.Results:①The level of IL-4 in HPV16(+) was significantly higher than that in HPV58(+)(P<0.05).The levels of IL-12 and IFN-γwere lower than that in HPV58(+)(P<0.05).②Significant differences of DNA state were found between the groups of HPV 16(+) and HPV58(+)(P<0.05)and the rate of HPV16 DNA integration was significantly larger than that of HPV 58 DNA.Conclusion:The infection of HPV16 and HPV58 not only can lead to reduction of IL-12,IFN-γand increasing of IL-4 in cervical local immune microenvironment but also lead to viral integration in cervical cells,resulting in cervical lesions and cervical cancer through the internal and external changes in cervical cells .HPV16 is more likely to cause cervical cancer tissue than 58.

Objective　To study the corelation between patient with inflammatory polyp of large intestine and the changes of immunologic function. Methods　Polyps of large intestine were extirpated from 120 patients with fiberoptic colonoscope and the pathological changes were studies. IgG subclass and T cell subsets in the peripheral blood were determined by ELISA and IFA methods. Similar parameters were determined in 30 cases of chronic colitis as control. Results　CD8 in patients were lower than that of the control and CD4/CD8 were increased compared with those in control. Conclusion　Disorder of humoral and cellular immunity might play an important role on the pathogenesis of polyp of large intestine.

Objective　To investigate the relationship between allergic reaction and fungus sensitinogen in patients with chronic colitis. Methods　Skin test with 3 groups of fungus allergen (6 types), eosinophil detection in serum and intestinal secretion and serum specific IgE (SIgE) test were tested in 246 patients with chronic colitis. The other 61 patients with chronic diarrhea were served as control. Results　Fungus positive was found in 110 patients (43.09%) in dermal fungus allergen test, but only 8.20% in control (P<0.01). In patients with chronic colitis, the positive rates of eosinophil in intestinal secretion and specific IgE induced by fungus allergen were 29.35% and 41.60% respectively. Conclusion　It is indicated that some patients with chronic colitis have correlation with allergic reaction of digestive system induced by food with fungus allergen.
