The changes of interstitial cells of Cajal(ICC)distribution and connexin 43(Cx43)expression in gastric muscle layers were assayed in gastroparesis models of streptozotocin-induced diabetic rats.The results showed that gastric emptying was significantly delayed,the contraction frequency and amplitude of gastric muscle segments were greatly decreased,Cx43 gray values were significantly increased and Cx43 distributed homogeneously with ICC immunopositivity in the model rats.These changes appear to be related to the pathogenesis of diabetic gastroparesis.

Objective To evaluate the value of 64-slice spiral CT angiography based on pre- contrasted raw data in diagnosing pulmonary arteriovenous fistula.Methods 64-slice spiral CT plain scan and enhanced scan was performed in 16 patients with pulmonary arteriovenous fistula,pulmonary angiography based on pre-contrast and post-contrast raw data was performed respectively,including maximum intensity projection(MIP),shaded-surface display(SSD),and volume rendering(VR).According to the results of angiocardiography and surgical findings,comparson of the three methods was made in the display of PAVF in pre-contrast and post-contrast phase images.Results 8 of the 16 PAVF cases were single lesion,8 cases were multi-lesions.30 PAVF lesions were found in all the patients.MIP,SSD and VR based on pre-contrast raw data displayed PAVF lesions in 20,14,and 22,respectively.The combination of the 3 methods based on pre-contrast raw data could show 26 PAVF lesions.MIP,SSD,and VR based on post-contrast raw data displayed PAVF lesions in 24,18,and 30,respectively.The combination of the 3 methods based on post- contrast raw data could show 30 PAVF lesions.Conclusion 64-slice spiral CT angiography based on pre- contrasted raw data can clearly show the position,number,and shape of PAVF lesions,which is of great value in diagnosing PAVF.

Objective To improve objectivity and accuracy of the diagnosis,prognosis,treatment efficiency and observe the levels of cognitive and intelligent deficits of children with attention deficit hyperactive disorder(ADHD).Methods Event related potentials(ERP)P3 wave test provocated by audition and Wechsler intelligence scale for children(C-WISC) test were detected and compared in 60 children with ADHD(ADHD group) and 60 cases of healthy children(healthy control group).The ERP P3 wave test results between 2 groups of children which had different intelligent balance ability were also compared.Results Compared with the healthy control group,there was a significantly longer latency of P3 wave(P

Objective To explore the correlation between myeloperoxidase (MPO) genetic variation and coal-burning endemic fluorosis, and to understand the influence of integrated intervention including stove changes and health education on people’s health in the area. Methods In 2007, coal-burning endemic fluorosis disease areas were selected in Bijie City, Guizhou Province. No stove changes in Yachi Town, 150 patients with dental fluorosis were selected as fluorosis non-intervention group, and the intervention group was 150 patients in Changchun Town where the stoves were changed 2 years ago. The population in control group was selected in an area with non-endemic fluorosis in Changshun County. The mRNA expressions of MPO in leukoxytes were detected by real-time PCR. HepG2 cells were cultured in vitro and divided into four groups: pGL3-A group, pGL3-G group, pGL3-Control group and pGL3-Basic group. pGL3-A and pGL3-G were recombinant plasmid, while pGL3-Basic as a blank control and pGL3-Control as a positive one. The internal reference plasmid pRL-TK co-transfected the HepG2 cells with pGL3-G, pGL3-A, pGL3-Basic and pGL3-Control, respectively. The influence of sudden change of MPO gene promoter on the gene transfection activity was evaluated by a dual luciferasereporter gene system. Results The expression level of MPO mRNA in peripheral blood leukocytes in non-intervention group(0.054 ± 0 . 003 ) were higher than control and intervention groups (0.019 ± 0.004,0.019 ± 0.003, all P<0.05), and no significant change was found between intervention group and control group(P>0.05). After the MPO-463G/A locus genetic variation occured, the luciferase reporter gene expression level of the recombinant plasmid pGL3-G(0.753 4 ± 0.086 6) was higher than that of the pGL3-A(0.490 0 ± 0.022 3, P < 0.05). Conclusions The study on MPO gene promoter-463G/A locus has prompted that MPO gene allele may be a protective factor to coal-burning fluorosis. The integrated interventions have a role in the prevention and treatment of endemic fluorosis.

Marginal bone loss during bone healing exists around non-submerged dental implants. The aim of this study was to identify the relationship between different degrees of marginal bone loss during bone healing and the salivary microbiome. One hundred patients were recruited, and marginal bone loss around their implants was measured using cone beam computed tomography during a 3-month healing period. The patients were divided into three groups according to the severity of marginal bone loss. Saliva samples were collected from all subjected and were analysed using 16S MiSeq sequencing. Although the overall structure of the microbial community was not dramatically altered, the relative abundance of several taxonomic groups noticeably changed. The abundance of species in the phyla Spirochaeta and Synergistetes increased significantly as the bone loss became more severe. Species within the genus Treponema also exhibited increased abundance, whereas Veillonella, Haemophilus and Leptotrichia exhibited reduced abundances, in groups with more bone loss. Porphyromonasgingivalis, Treponemadenticola and Streptococcus intermedius were significantly more abundant in the moderate group and/or severe group. The severity of marginal bone loss around the non-submerged implant was associated with dissimilar taxonomic compositions. An increased severity of marginal bone loss was related to increased proportions of periodontal pathogenic species. These data suggest a potential role of microbes in the progression of marginal bone loss during bone healing.

Objective To explore the relationship between -262C/T and -21A/T polymorphisms of catalase(CAT) gene and coal-burning borne fluorosis. Methods In 2007, 150 villagers were taken as a nonintervention group in Bijie city from the village of coal-burning borne fluorosis areas with unchanged cooking stoves;150 villagers were taken as the intervention group from the town of Changchun county where cooking stoves changed; 150 villagers were taken as control from non-endemic fluorosis areas in Baiyun town of Changshun county.PCR-restriction fragment length polymorphism were employed to detect genotypes of CAT-262C/T and CAT-21A/T polymorphism of CAT gene. Results The genotypic frequencies of CAT-262C/T and CAT-21A/T in nonintervention group,intervention group and control group were in line with Hardy-Weinberg equilibrium law (P＞ 0.05 ).The genotypes of CC and CT were detected while no TT were detected for CAT-262C/T polymorphism; the genotypes of AA, AT and TT were detected for CAT-21A/T. The genotype frequencies of CAT-262 CC, CT in control group, intervention group and non-intervention group were (89.33%(134/150), 10.67%(16/150); 88.67%(133/150), 11.33% (17/150),93.33% (140/150),6.67% (10/150), respectively. The gene frequency of C in control group, intervention group and non-intervention group were (94.67% (284/300), 94.33% (283/300),96.67%(290/300), respectively. The gene frequency of T in control group, intervention group and non-intervention group were 5.33%(16/300), 5.67%(17/300), 3.33%(10/300), respectively. The genotype frequencies of CAT-21 AA,AT and TT in control group, intervention group and non-intervention group were 48.67%(73/150),46.00%(69/150),5.33%(8/150) ,52.67%(79/150) ,38.00%(57/150) ,9.33% (14/150) ,51.33%(77/150) ,38.00%(57/150), 10.67%(16/150), respectively. The gene frequency of A in control group, intervention group and non-intervention group were 71.67%(215/300),71.67%(215/300),70.33%(211/300), respectively. The gene frequency of T in control group, intervention group and non-intervention group were 28.33% (85/300),28.33% (85/300),29.67% (89/300),respectively. CAT-262C/T and CAT-21A/T genotype and allele frequencies in the control group, the intervention group and non-intervention group showed no significant differences in the distribution(x2= 0.331,0.336, all P ＞0.05 ). Conclusion CAT-262C/T and CAT-21A/T polymorphism is not associated with coal-burning borne fluorosis.

Background Infective keratopathy is a key cause of corneal blindness in China,and fungal keratitis is proved to have a higher incidence and bigger threats in infective keratitis.Researches showed that topical immunology plays an important effect during the development of fungal keratitis,but its mechanism is still studying.Objective This experiment was to explore the critical immunocyte during the process of fungal keratitis.Methods Forty-eight SPF 12-week-old male C57BL/6J mice were included and randomized into the control group and model group.The fungal keratitis model closely mimicking human cornea infections was established in the mouse using scratch followed by incubation of fusarium solani on the cornea,and the mice in the control group scratched on the cornea only.Cornea was examined under the slit lamp at 0,6,9,12,24,72 and 120 hours after operation.The severity of keratomycosis was clinically scored based on the literature criteria.The inflammatory cells were identified using immnofluorescence label,and the number of the inflammatory cells was calculated and compared among different groups and time points.This study complied with the Statement of ARVO in the use of experimental animal.Both Experimental Animal Ethic Commission in Zhengzhou University and Life Science Management Commission approved this study proposal.Results After inoculation of fusarium solani,typical fungul keratitis signs were seen on the cornea.Severe corneal opacifieation occurred within 24 hours and peaked at 72 hours.However,only mild edema of cornea was exhibited and gradually recovered normal in the control group within 24 hours.The clinical score of inflammation was higher in the model group in various time points than that in the control group,and it was seen that 24-72 hours after operation,the score attached peak in the model group with a significant difference in comparison with the control group(P＜0.01).In 9,12,24,72 and 120 hours after operation,the number of neutrophil cells was significantly increased in the model group compared with control group (P＜0.05),and that in 12,24,72 hours after operation was significantly higher than the 6 hours(P=0.004,0.000,0.001).However,no significant differences were seen in the number of neutrophil cells between 9 or 120 hours and 6 hours after operation(P=0.772,0.323).The number of T lymphocytes in cornea was significantly increased in 72 and 120 hours in comparison with 6 hours in the model group(P=0.000,0.000),and from 72 to 120 hours after operation,the number of T lymphocytes was significantly higher than that of the contral group (P＜0.01).The neutrophil cell number was positive correlated with the inflammatory score in the early phase (r =0.593,P =0.000).T limphocyte emerged in late phase but no significant correlation with the clinical score (r＝0.315,P=0.062).Conclusions Neutrophil cells play a critical role in the development of fungal keratitis in early stage.
