Objective To investigate the prevalence features of helicobacter pylori (Hp) infection,anemia and iron deficiency in a po-pulation of Wuhan children with 2 to 6 years old,and the relationship between Hp infection and anemia,iron deficiency in the children.Methods Randomly taking 95 children who had taken tests in our hospital's check-up centre in 2008 as the study objects,2 kinds of exa-mination were employed to detect Hp infection.Serum levels of Hp-IgG were measured by enzyme linked immunosorbent assay (ELISA) methods to evaluate past infection.The 14C urea breath test (14C-UBT) was conducted to obtain information of the presence of current/active Hp infection.In the morning 3 mL fasting venous blood was collected to determine the serum levels of Hp-IgG antibodies and ferritin.Hemoglobin values were determined with a hemoglobinometer.Serum levels of C-reactive protein (CRP) were tested in order to determine whether the children had evidence of current inflammation or infection.In addition,demographic information such as age and gender of the children and information about their use of antibiotics within the prior month were recorded.All cases were divided into 2 groups including the Hp infection group and non-Hp infection group according to laboratory examinations,then the Logistic regression was applied to analyze the relationship between Hp infection and anemia,iron deficiency.The Kappa identity test was taked to compare the 2 measures.Results Of the 95 children,18.9% were anemic and 36.8% were iron deficient.Forty percent of the cohort had Hp-IgG antibodies,74.4% tested positive by the UBT.Presence of Hp-IgG emerged as a significant risk factor for anemia,iron deficiency in adjusted analysis controlling for demographic factors,current inflammation,and antibiotic use.Conclusions Findings from different measure of Hp may reflect different stages of infection,with UBT results reflecting an earlier stage of infection,and presence of Hp-IgG reflecting established Hp infection associated with anemia,iron deficiency.

Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

ObjectiveTo discuss the effect of neonatal behavioral neurological assessment (NBNA) and developmental screening test (DST) on newborns with hypoxic ischemic encephalopathy (HIE). MethodsNBNA was performed for 60 newborns with HIE within 12-14 days and DST was also performed at 6th month after birth.ResultsMild and severe degree HIE newborns with low NBNA scores had unfavorable prognosis. Conclusions NBNA and DST can provide evidence for early interference for newborn's HIE.

OBJECTIVETo explore the scavenging action of tenuigenin (TEN) on intracerebral amyloid β protein (Aβ) aggregation and the abnormal phosphorylated tau protein and its mechanism in Alzheimer's disease (AD) rats' brain.

METHODSAβ1-40 was injected into the right CA1 region hippocampus to establish the AD model. Successfully modeled rats were divided into the model group, the low, middle, high TEN group. Rats were administered with TEN (18.5, 37.0, 74.0 mg/kg) by gastrogavage. Besides, a sham-operation group was set up. Expression levels of Aβ1-40 and Tau p-Ser262 were detected by immunohistochemistry. Expression levels of ubiquitin (Ub) and Ub-protein ligase E3 were measured by Western blotting.The content of 26S proteasome was detected by ELISA.

RESULTSImmunohistochemical results showed that the number of Aβ and Tau p-Ser262 positively reacted neurons significantly increased in model group, when compared with the sham-operation group (P < 0.01). Results of Western blot showed expression levels of ubiquitinated protein were up-regulated and those of Ub-protein ligase E3 were down-regulated in the model group (P < 0.01). ELISA results showed that the content of 26S proteasome significantly decreased in AD rats' brain (P < 0.01). Compared with the model group, expression levels of Aβ1-40, Tau p-Ser262, and Ub significantly decreased; expression levels of Ub-protein ligase E3 apparently increased; the content of 26S proteasome significantly increased in each TEN treatment group (P < 0.05, P < 0.01). Best effect was shown in 37.0 mg/kg and 74.0 mg/kg TEN groups.

CONCLUSIONSUb proteasome pathway (UPP) participated in the occurrence of AD. TEN could obviously reduce intracere- bral Aβ1-40 accumulation and abnormal tau phosphorylation.

Objective To evaluate the clinical value of contrast-enhanced ultrasound (CEUS) in preoperative diagnosis of anal fistula. Methods Forty-five patients with fistula in ano were evaluated by physical examination, then CEUS were peformed by injecting SonoVue through the external opening to enhance the detection of the fistulous track and the internal opening. The results of CEUS were matched with surgical features to establish their accuracy in preoperative assessment of anal fistula. Results Simple typing fistula was found in 19 of 45 patients and 26 patients had complex fistulas. The accurate diagnostic rates by conventional ultrasound of simple typing fistula and complex fistulas were 89. 5% and 61.5%,respectively,the accurate diagnostic rates by CEUS of simple typing fistula and complex fistulas were 94. 7% and 92.3%, respectively, there was no significant difference between conventional ultrasound and CEUS about simple typing fistula( P ＞0.05), and there was significant difference about complex fistulas ( P ＜0. 05). Conclusions CEUS has a good visibility and accurate rate for diagnosis of anal fistula,It plays an important role for operation.

Objective To study the gait of children with spastic cerebral palsy (SCP) using plantar pressure measurement (PPM).Methods Twenty SCP children and 84 healthy children were recruited,and PPM was used to compare their gait cycle time,cadence,and standardized gait cycle parameters.Results Compared with the control group,gait cycle times in the SCP group were obviously prolonged,and their cadence was significantly slower.The side support phase and swing time in the SCP group were shorter,while the double support phase was longer than that of children in the control group.Conclusion PPM can be used to assess the gait of SCP children efficiently.

Objective To investigate the effect of telmisartan on the oxidative stress induced by high glucose in human umbilical vein endothelial cell (HUVEC) in vitro.Methods HUVEC were cocultured with telmisartan (1?10~(-6) mol/L) and various concentration of glucose(5,30 mmol/L) for 0,12,24,36,48 h respectively. The level of MDA in the supernatants of cultured endothelial cells was measured by thiobarbituric acid test,SOD was determined by xanthine oxidase test.The protein expression of peroxisome proliferator activated receptors ? (PPAR-?) in HUVEC 24 h was assessed by Western blot after treatments.Results High glucose significantly increase the levels of MDA (before:1.2?0.06 vs after:1.6?0.1 mmol/mL,P

Objective To explore the clinical characteristics, surgical treatment and related factors of traumatic implantation cyst of the iris. Design Retrospective cases series. Participants Thirty-six cases of traumatic implantation cyst of the iris. Methods Thir- ty-six cases of traumatic implantation cyst of the iris were reviewed. Main Outcome Measures Age, surgical history, history of disease, surgical method of patients. Results All cases of traumatic implantation cyst of the iris were secondary to perforating injury. 10 cases had been undertaken cataract surgery. The histories of disease in 6 months～1 year and 1 year～10 years were 30.56% respectively. Sur- gical exicision was taken in all cases. There were 2 recurrence cases. Conclusion Traumatic implantation cyst of the iris is almost see- ondary to perforating injury. Surgical excision is an effective strategy to treat this disease.
