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 study the role of nuclear factor (NF)-kappaB pathway with p38MAPK in Curcuma wenyujin diterpenoid compound C (CDCC) fighting against inflammation and inducing gastric cancer cell apoptosis by stimulating gastric cell SGC7901 with tumor necrosis factor-alpha (TNF-alpha).

METHODSHuman umbilical vein endothelial cells (HUVECs) and human gastric cancer SGC-7901 cells were in vitro acted by CDCC in different concentrations at different time points. Their growth inhibition ratios were measured by MTT assay. The apoptosis rate of gastric cancer cells was detected by Annexin V-FITC/PI double staining. Nuclear translocation of p65 was detected by cell immunofluorescence. Expression levels of p38MAPK/P-p38MAPK, p65/P-p65, and Caspase 3/P-Caspase 3 were measured by Western blot.

RESULTSCDCC had significant inhibitory effect on the proliferation of SGC-7901. It also could effectively induce the apoptosis of gastric cancer cell SGC-7901. It also could reduce nuclear translocation of p65 in gastric cancer cell SGC-7901. Results of Western blot indicated that expression levels of p38MAPK and p65 were reduced and the expression level of Caspase-3 was elevated along with increased concentrations of CDCC (P<0.05).

CONCLUSIONApoptosis executive protein Caspase 3 activated by regulating p65 via p38MAPK might be one of possible mechanisms for CDCC fighting against inflammation and gastric cancer.

The present study was carried out to determine the role of 5-HT(1A) receptors in the generation and modulation of basic respiratory rhythm. Neonatal (aged 0-3 d) Sprague-Dawley rats of either sex were used. The medulla oblongata slice was prepared and the surgical procedure was performed in the modified Kreb's solution (MKS) with continuous carbogen (95% O2 and 5% CO2), and ended in 3 min. In cold MKS, a 600-700 microm single transverse slice was cut, which was rostral to the edge of area postrema and retained the hypoglossal nerve roots and some parts of the ventral respiratory group. The preparation was quickly transferred to a recording chamber and continuously perfused with carbogen-saturated MKS at a rate of 4-6 mL/min at 27-29 degrees C. Glass adsorb-electrodes containing Ag-AgCl needle were attached to the ventral roots of the hypoglossal nerve. Respiratory rhythmical discharge activity (RRDA) of the rootlets of hypoglossal nerve was recorded. Ten medulla oblongata slice preparations were divided into two groups. In group I, 5-HT(1A) receptor specific agonist (+/-)-8-hydroxy-2-(di-N-propylamino)tetralin hydrobromide (8-OHDPAT, 20 micromol/L) was added into the perfusion solution for 10 min first, after washing out, the 5-HT(1A) antagonist [4-iodo-N-[2-[4-methoxyphenyl]-1-piperazinyl]ethyl]-N-2-pyridynyl-benzamide hydrochloride] (PMPPI, 10 micromol/L) was applied to the perfusion solution for 10 min. In group II, after application of 8-OHDPAT for 10 min, additional PMPPI was added into the perfusion solution for 10 min. The discharges of the rootlets of hypoglossal nerve were recorded. Signals were amplified and band-pass filtered (100-3.3 kHz). Data were sampled (1-10 kHz) and stored in the computer via BL-420 biological signal processing system. Our results showed that 8-OHDPAT increased the respiratory cycle (RC) and expiratory time (TE) as well as reduced the integral amplitude (IA), but the changes of the inspiratory time (TI) were not statistically significant. PMPPI induced a significant decrease in RC, TE and TI, but the changes of IA were not statistically significant. The effect of 8-OHDPAT on the respiratory rhythm was partially reversed by additional application of PMPPI. Taken together with previous results, 5-HT(1A) receptors may play an important role in the modulation of RRDA in the medulla oblongata slice preparation of neonatal rats.

OBJECTIVETo compare postoperative blood loss under different negative pressures of drainage after total hip arthroplasty for the treatment of femoral neck fractures.

METHODSFrom January 1st to December 30th 2013, 74 patients with femoral neck fractures treated with total hip arthroplasty were randomly divided into two groups: high negative pressure drainage group and low negative pressure drainage group. In high negative pressure drainage group, there were 34 cases including 10 males and 24 females, with a mean age of (75.94 ± 9.02) years old, and the patients were treated with 60 kPa negative pressure of drainage. In the low negative pressure drainage group, there were 40 cases including 13 males and 27 females, with an average age of (74.93 ± 8.90) years old, and the patients were treated with 30 kPa negative pressure of drainage. The amount of total drainage, total blood loss, and hemoglobin change were compared between these two groups.

RESULTSAll the patients got primary healing without infections. In high negative pressure drainage group,the change of hemoglobin was (41.74 ± 15.69) g/L, total blood loss was (1,217.73 ± 459.50) ml and the drainage volume was (312.94 ± 103.44) ml; while in low negative pressure drainage group,the results were (34.90 ± 12.90) g/L, (904.01 ± 381.58) ml and (129.25 ± 44.25) ml separately. All the results in high negative pressure drainage group were higher than those in the other group. Three days after operation, the change of hemoglobin was (46.00 ± 13.29) g/L and total blood loss was (1,304.72 ± 421.75) ml; while in low negative pressure drainage group, the changes of hemoglobin was (43.87 ± 11.39) g/L and total blood loss was (1,196.78 ± 344.20) ml; there were no statistically significant differences between two groups.

CONCLUSIONWhen placing drainage devices after total hip arthroplasty for the treatment of femoral neck fractures, the level of negative pressure should be chosen according to preoperative level of hemoglobin and HCT in patients. For old patients with femoral neck fracture, low negative pressure is more suitable.

AIM: To observe the curative effect of excision combined with concavity-convex amniotic membrane transplantation in the treatment of intraepithelial epithelioma.

METHODS:Totally 24 cases of intraepithelial neoplasia(24 eye)diagnosed in our department were studied. The tumors of 12 cases were removed and the wound were covered by the concavity-convex amniotic membrane in the conjunctiva and part of the resection, and other 12 were covered by the amniotic membrane. The effect of these two surgeries were assessed via observing the epithelial healing, degradation of biological amnion, tear break-up time, tumor recurrence and other complications. The resection of the tumor were analyzed histopathologically.

RESULTS: The pathological results of all the patients were epithelial carcinoma. There were 24 patients that diagnosed -intraepithelial epithelioma pathologically. The conjunctival epithelium healed rapidly and were completed in 5d after operation in both groups. The amniotic membrane was completely degraded in about 14d. Postoperative visual acuity improvement was not statistically significant in two groups. All patients were followed up for more than 1y. The recurrence rates were significantly lower in concavity-convex amniotic membrane group than that in amniotic membrane group.

CONCLUSION: Tumor resection combined with concavity-convex amniotic membrane transplantation is an effective operation method for the treatment of intraepithelial epithelioma.
