Nonalcoholic fatty liver disease (NAFLD)and gallstone disease (GD)are considered the manifestations of metabolic syndrome in the liver and gallbladder.NAFLD and GD are closely related to insulin resistance (IR),obesity,dyslipidemia,abnormal glucose metabo-lism,and so on.Worldwide studies,which have been reviewed,show that both NAFLD and GD have the common risk factors,such as IR, obesity,dyslipidemia,abnormal glucose metabolism,and middle-aged and elderly women.NAFLD is the risk factor for GD.GD,closely related to nonalcoholic steatohepatitis and liver fibrosis,accelerates the progression of NAFLD.Thus,it is considered that the prevention and treatment of NAFLD can reduce the incidence of GD,and the progression of NAFLD can be delayed by the prevention and treatment of GD.

Objective To find the characteristics of stress distribution on condyle during different vertical distances of edentulous jaw.Methods Three dimensional finite element models of the mandible and temporomandibular joint were established with the complete dentures in different heights by helix-CT scanned transverse sections.The stress distribution of the condyle was analyzed under load.Results The compressive stress and tensile stress coexisted on the whole condyle with the different vertical distances.The trend of distribution was consistent practically,but the stress presented a large difference on different locum.With the decrease of the vertical distance(from H-2 to H-6),the stress presented a decreasing trend but an increasing trend at H-8.Conclusion Changes in the vertical distance produce different effects of stress on edentulous jaw under the same load.

METHODS: Measuring the contents of endothelin-1(ET-1),atrial natriuretic factor(ANF),cGMP in plasma and bronchoalveolar lavage fluid (BALF) of guinea pigs. RESULTS: The contents of ET-1, ANF and cGMP in asthma group were higher than that of the control group; There was a significant negative correlation between ET-1 and ANF( r=-0.638,P

Objective To study inflammatory cytokines changes in brain tissue of neonatal rats with periventricular leukomalacia (PVL).Method A total of 80 neonatal SD rats (P3) were randomly assigned into 2 equal groups,sham-operated group and PVL group.Rats in each group were further assigned into four subgroups (12,24,48,72 h),with 10 rats in each subgroup.The hypoxic-ischemic PVL modal were established following the procedure:first,isolation and ligation of left common carotid artery,and then exposed to 8％ O2 and 92％ N2 for 2.5 h.The sham-operated rats were processed with isolation of left common carotid artery only.Rats of the four subgroups were sacrificed at 12,24,48 h and 72 h respectively,then the brains were rapidly removed in corresponding time.Pathological changes of brain tissues were observed using HE stain.The mRNA expression levels of tumor necrosis factor α(TNF-α)and inter leukin-1β (IL-1β) were assessed using real-time quantitative PCR assays,the protein levels of TNF-α and IL-1β were detected using enzyme linked immunosorbent assay method.Result The brains tissues of rats in PVL group showed remarkably hyperemia and edema,with left ventricle enlargement.Periventricular white matter structure was disintegrated comparing with sham-operated group.The expression of TNF-α and IL-1 β mRNA in PVL group increased significantly,reaching peak by 24 h and then gradually decreased 72 h after the procedure.The mRNA levels of TNF-c and IL-1 β were significantly different between each two time points of 12,24 h and 48 h in PVL group (P ＜0.05).However,there was no differences between 72 h and 48 h within PVL and sham-operated group group(P ＞0.05).In PVL group,the protein expression trends of TNF-α and IL-1 β were similar to mRNA expression trends.Moreover,the protein levels were significantly different between each two time points of TNF-α and IL-1 β,respectively (P ＜ 0.01).The protein expression levels of TNF-α were different at each time point between PVL group and sham-operated group[(189.2 ± 20.4) pg/ml vs.(131.4 ±5.2) pg/ml at 12 h,(213.8 ± 16.7) pg/ml vs.(127.7 ±7.4) pg/ml at 24 h,(181.7 ± 15.0) pg/ml vs.(126.3 ± 6.0) pg/ml at 48 h,(159.6 ± 25.3) pg/ml vs.(131.4 ± 6.0) pg/ml at 72 h;P ＜0.01].The protein levels of IL-1β were different between the two groups only at 24 h and 48 h.[(121.8 ±30.0) pg/ml vs.(67.4 ± 13.7) pg/ml,(83.3 ± 15.7) pg/ml vs.(65.3 ± 14.9) pg/ml;P ＜0.05].In sham-operated group,no differences of TNF-α and IL-1 β protein levels were found between any different time points (P ＞ 0.05).Conclusion Inflammatory cytokines such as TNF-α and IL-1β are involved in ischemic-hypoxia induced PVL.Dynamic detection of inflammatory factors is expected to be an important method of early diagnosis,assessment of treatment efficacy and prognosis of PVL.

Objective To study the relationship between helicobacter pylori(Hp) infection and iron deficiency anemia(IDA) in children. Methods The observation group contained 26 cases and control group 22 cases.Seroferroprotein(SF) and blood routine were detected.Results There was statistically significant difference in both groups on the SF,hemoglobin,red blood cellcount,mean corpuscular volume and mean corpuscular hemoglobin concentration (P0.05). Conclusion Hp infection may be related to IDA in children.

Objective To explore the property and diagnostic significancec of transnasal gastroscope(EG-470N5)in children with upper gastrointestinal tract disorders.Methods Sixty children with upper gastrointestinal tract disorders were examined by using EG-470N5.The scope was inserted either through nose(n=28)or via mouth(n=32).Beside the routine preparations,nasal spray of lidocaine or nasal drib of ephedrine was added to those who received nasal intubation.Results Examination of upper gastrointestinal tract subjects in all succed with no obvious side response in 28 cases(46.7%)who received the examination via nose,27 cases(45%)had mild nausea and 5 cases(8.3%)had serious nausea and dysphoria.Children with esophagostenosis and pyloristenosis and 2-day-old neonate were examined without adverse effect.Conclusions Transnasal gastroscope is preponderant to children due to its slim diameter and supple body,especially to those having swallow difficulty and confined tract.It is more favorable practical prospect than routine gastroscope.

Objective To investigate clinical feature,diagnosis and prognosis of eosinophilic gastroenteritis(EG),and to analyze the causes of misdiagnosis.Methods Eleven children diagnosed as EG were studied.Their history,clinical manifestations,laboratory tests and endoscopies and treatment,follow-up data were analyzed.The data were analyzed by SPSS 10.0 software.Results 1.The children with EG usually had abdominal pain(5 cases),diarrhea(7 cases),hemafecia(5 cases) and sometimes with fever(2 cases).2.EG and allergy in children was closely related with disease(54.55%).3.Peripheral blood eosinophil(EOS) count increased significantly,and declined when symptoms eased(18.18%).4.Endoscopic manifestations were not specific,the mucosa could see sheet erosion,shallow ulcers,congestive spots or bleeding spots,mainly in antrum,duodenum,terminal ileum,ileocecal junction.The biopsy showed that a large number of EOS infiltration.5.Imaging were not specific,CT or gastrointestinal barium meal examination did not show special often(90.91%).When muscular wall was affected(9.09%),imaging presentations of EG could be partly obstructive.6.Glucocorticoid therapy could relieve symptoms and EOS.Symptoms probably recured by good prognosis.7.EG was a self-limiting allergic diseases,although the attack may be repeated.After long-term follow-up,most had good prognosis and without malignant.Conclusions Clinical and endoscopic presentations of EG are not specific,therefore the presence of EOS in gastrointestinal mucosa strongly indicate the diagnosis.It was easy to misdiagnosis.Biopsy pathology and cli-nical characteristics are the key to diagnosis.
