Objective:To construct the Helicobacter pylori infected C57BL/6 mice model to observe the activation of NOD1/NF-κB signaling pathways in the gastric tissues,and study its roles in inflammatory response during Hp infection.Methods:6-8 week-old C57BL/6 mice were randomly divided into two groups,the Hp infection group and the control group,and mice were given by gavage every 48 h for five times with Hp or PBS,respectively.All the animals were sacrificed at different time point and the gastric tissue were stained with hematoxylin-eosin( HE);The mRNA expression of NOD1 and RIP2 in gastric tissues were examined by RT-PCR;Levels of IFN-βand IP-10 in mice serum were assessed by ELISA;Nuclear translocation of p65 in gastric tissue was detected by Western blot.Results:Hp infection elicits an inflammatory cell response,glands in gastric tissue were reduced or atrophic,as compared with that in the control group.The levels of IP-10 and IFN-βincreased in the model group, and peaked at 16 weeks after Hp infection.Hp infection increased the mRNA expression of NOD1 and the p65 content in nuclear between 24-120 h(P<0.05),and the highest level at 48 h,subsequently the expression levels were began to decrease.The mRNA expression level of RIP2 was up-regulated after Hp was administrated, peaked at 48 h and declined after 72 h.However, the expression levels would rise again at 120 h.Conclusion: Hp infection can activate the NOD1/NF-κB signaling pathways and induce the production of IFN-βand IP-10 in gastrics of mice.

To explore the relationship and possible mechanism of reproductive function of bisphenol A (BPA) with polycystic ovary syndrome (PCOS).Serum specimens were collected from 43 PCOS patients and 37 healthy women.And the level of BPA was detected by enzyme-linked immunosorbent assay (ELISA).The serum level of BPA in PCOS were significantly higher than that in the control group.And the inter-group difference was significant (P ＜ 0.05).The patient level of BPA was positively related with obesity and basic luteinizing hormone (LH) (P ＜ 0.05).In the PCOS group,no significant correlation existed between hyperandrogenemia and non-hyperandrogenemia (P ＞ 0.05).Although no difference existed between insulin and non-insulin resistance,the level of BPA in insulin resistance group was lower than in non-insulin resistance group.A higher level of BPA may be associated with obesity and basic LH in PCOS.

Objective To explore the feature of functional connectivity of default mode network (DMN) and salience network (SN) in unmedicated schizophrenia patients during a resting state by functional magnetic resonance imaging (fM-RI). Methods The SPM8 and DPARSFA softwares combined with independent component analysis (ICA) were used to in-vestigate functional connectivity (FC) of the DMN and SN in 27 unmedicated patients with schizophrenia and 27 age-and gender-matched healthy controls. Results Concerning the DMN, patients with schizophrenia showed decreased FC in right inferior frontal gyrus , right precuneus(unadjusted P<0.05)and increased FC in right middle cingulate gyrus, left middle frontal gyrus(unadjusted P<0.05). With regard to the SN, patients showed reduced connectivity in left inferior frontal gyrus, right inferior frontal gyrus, left anterior cingulate, left postcentral gyrus(unadjusted P<0.05)and increased connectivity in left superior temporal gyrus(unadjusted P<0.05). Correlation analyses showed that the increased FC of left superior temporal gyrus significantly correlated with PANSS-positive symptoms(r=0.568,P=0.002)and decreased FC of right precuneus significantly negatively correlated with delusion symptom(r=-0.458,P=0.016). Conclusion This study provides evidence for resting state functional abnormalities of DMN and SN in unmedicated schizophrenia patients. These aberrant function connectivities in some brain regions of the two networks could be a source of abnormal introspectively-oriented mental actives.

Objective To investigate the clinical characteristics,the diagnosis and therapy of synchronous multiple primary esophageal carcinoma.Methods Thirty-two cases of synchronous multiple primary esophageal carcinoma were collected from January 1980 to December 2010 and their clinic data were retrospectively analysised.Results In the whole group,there were totally 66 lesions in 30 cases of double primary lesion and 2 cases of three primary lesion.The length of the lesions were 1 cm to 6.5 cm,and there were 22 lesions in cervical esophagus,10 in upper thoracic esophagus,19 in midthoracic esophagus and 15 in lower thoracic esophagus.Within the 66 lesions,65 lesions were squamous cell carcinoma and 1 was adenocarcinoma.The mucosa between the lesions were normal,with a distance of 4 cm to 9.5 cm,average 7.1 cm.Thirty-two patients with synchronous multiple primary esophageal carcinoma received surgery.Among 32 cases,26 of them were given definite diagnosis before operation.Four of them had exploratory operation,one patient underwent palliative resection,27 patients underwent radical resection.Two cases of the pathologic results of esophageal stump showed carcinoma after operation.The complications occurred in 8 patients.Twenty-eight cases were followed up after operation,the 1,3 and 5-survival rate were 76.9％,43.3 and 14.8％,respectively.Conclusion General pre-operation examination can significant helpful for the definite diagnosis of synchronous multiple primary esophageal carcinoma and surgical treatment is better choice for this disease.

Objective To investigate the effect of preoperative angiography and intraoperative Doppler blood flow detection in the surgery of colonic interposition for esophageal.Methods Thirty-seven patients who underwent the surgery of colonic interposition for esophageal were chosen,17 cases received colonic interposition for esophageal routine operation (routine group),and 20 cases received preoperative angiography of superior and inferior mesenteric arteries and intraoperative Doppler blood flow detection (improved group),the clinical efficacy was observed.Results Routine group occurred anastomotic leak in 4 cases on postoperative 6-15 d,operation time was (367.0 ± 53.3) min,and improved group occurred anastomotic leak in 1 case on postoperative 7 d,operation time was (302.0 ± 67.1) min,the operation time between two groups had significant difference (P ＜ 0.05).Conclusions The adoption of preoperative angiography and intraoperative Doppler blood flow detection can real-time directly display the vascular morphology of transplanted colon segment,observe the traveling direction and distribution of mesenteric arteries,provide accurate and rehable evaluation of blood vessel of transplanted colon,which can conduct to the optimum selection of transplanted colon and reduce the incidence of postoperative complications.
