Objective To explore the mediating role of self-confidence in the parental rearing style and facing-audience com munication apprehension(FACA).Methods The Chinese College Students' Facing-audience Communication Apprehension Scale (revised version of 2011),the Short-form Egna Minnen av Barndoms Uppfostran for Chinese(s-EMBU-C) and the Overall Self-confidence Questionnaire Version of College Students were adopted to survey on 1 072 college freshmen from Guizhou Province.Results FACA in the freshmen of non-one-child was significantly higher than that in the freshmen of one-child,FACA in the freshmen of good performance was significantly lower than that in the freshmen of middle and poor performance;FACA of college freshmen,parental rearing style and self-confidence were significantly correlated with each other;self-confidence played a complete mediated role between the parental care and FACA,and a partial mediated role between the parental control and FACA.Conclusion Self-confidence has significant mediate effect between the parental rearing style and FACA of college freshmen.

Objective To investigate the correlation between helicobacter pylori infection and pathological characteristics of gastric mucosal in the elderly.Methods Retrospective analysis was conducted in 278 patients with benign upper gastrointestinal disease from January 2014 to June 2014.The patients were examined by endoscopy and 13C-UBT,and divided into elderly group (aged 60 years and over,n=111) and non-elderly group (aged＜60 years,n=167).The relationships between Hp infection and pathological changes in gastric mucosal tissue (severe chronic inflammation,neutrophil infiltration,lymph follicles,gastric gland atrophy,intestinal metaplasia) were analyzed.Results There was no significant difference in helicobacter pylori infection rate between the elderly group and non-elderly group [27.0％ (30/111) vs.36.5％ (61/167),P＞0.05].The rate of gastric gland atrophy was higher in elderly group than in non-elderly group [13.5％ (15/111) vs.6.0％ (10/167),P=0.028].The rates of severe chronic inflammation,neutrophil infiltration,lymph follicles,gland atrophy and intestinal metaplasia were 73.6％,70.3％,14.3％,18.7％,29.7％ in patients with helicobacter pylori infection,which were higher than those in patients without helicobacter pylori infection (19.8％,3.2％,0.5％,4.3％,8.6％,respectively,all P=0.000).Removing the factor of Hp infection,the rates of glands atrophy and intestinal metaplasia were higher in elderly group than in non-elderly group (8.6％ vs.0.9％,43.3％ vs.23.0％,P=0.013 and 0.045).Conclusions Helicobacter pylori infection correlates with severe chronic gastric mucosal inflammation,neutrophil infiltration,lymph follicles formation.Gland atrophy and intestinal metaplasia are related to the Hp infection,and age is also their influencing factor.

ObjectiveTo observe the effects of salmeterol fluticasone on the glucose metabolism and bone density of the elderly patients with chronic obstructive pulmonary disease (COPD) combined with type 2 diabetes mellitus (T2DM).MethodsThirty-one patients with COPD combined with T2DM were divided into 2 groups by random digits table,14 cases in control group were given conventional therapy,17 cases in experimental group were given conventional therapy and fluticasone propionate 50/500 μg,twice a day,for 3 months.The fasting blood glucose,postprandial 2 hours glucose,glycosylated hemoglobin,plasma cortisol and bone density respectively before and after treatment were detected.ResultsIn experimental group,the fasting blood glucose,postprandial 2 hours glucose,glycosylated hemoglobin and bone density before treatment was (5.25 ± 0.21 ) mmol/L,(7.14 ± 0.33 ) mmol/L,(5.58 ± 0.26 )％,( 1.96 ± 0.11 ) g/cm2,and after treatment was(5.31 ± 0.27 ) mmol/L,(7.22 ± 0.29 ) mmol/L,(5.67 ± 0.23 )％,(2.03 ± 0.15 ) g/cm2,there was no significant difference (P ＞ 0.05).In control groups,the fasting blood glucose,postprandial 2 hours glucose,glycosylated hemoglobin and bone density before treatment was (5.33 ± 0.35) mmol/L,( 7.26 ± 0.29 ) mmol/L,( 5.62 ± 0.19 )％,( 1.88 ± 0.20 ) g/cm2,and after treatment was ( 5.36 ± 0.31 ) mmol/L,(7.30 ± 0.35 ) mmol/L,( 5.69 ± 0.26 )％,( 1.98 ± 0.17 ) g/cm2,there was no significant difference (P ＞ 0.05 ).There was no significant difference in plasma cortisol before and after treatment in two groups (P ＞0.05).ConclusionInhaling salmeterol fluticasone for elderly patients with COPD combined with T2DM is safe.

Objective To analyse the normal helical CT appearances of the bronchial stump or anastomosis after pulmonectomy for central bronchial carcinoma.Methods The available 110 contrast-enhanced spiral CT images in 55 patients undergone different surgical procedures for central bronchial carcinoma were evaluated retrospectively.Results The CT findings of bronchial anastomosis in shape appeared as smooth,concave and convex,sharp angle,obtuse angle,spininess,irregulated or short tube.The thickness of anastomosis was (3.26?1.46) mm.Conclusion Spiral CT can display the bronchial anastomosis clearly after pulmonectomy for central bronchial carcinoma.

Objective To assess the usefulness of spiral CT examination in detecting the local recurrence and the metastatic lymph nodes of chest in the patients with post-pulmonectomy for central lung cancer.Methods The data of 110 contrast spiral CT of chest in 55 patientswith central bronchial carcinoma post-operation were retrospectively analysed.Results 12 person-time in 9 cases recurred in thebronchial stump or anastomose.The short diameter of lymph nodes in the thorax ≥1 cm was showed in 33 person-time of 26 cases,of them,14 cases was considered as metastasis in combination with the clinical data.Conclusion Spiral CT is the one of the best examination indetecting the post-operation recurrence in the patients with central bronchial carcinoma,but it is still of limitation in evaluating the nature of lymph nodes.

Objective To investigate the accumulation and maturation status of pulmonary conventional dendritic cells (cDCs) in the early phase of acute lung injury (ALI),and to explore the way of the inflammatory responses and lung injury modulated by cDCs in vivo.MethodsMale C57BL/6 mice were randomly ( random number) divided into the normal control group,6 h-ALI group and 24 h-ALI group.Murine model of ALI was made by intra-tracheal administration of lipopolysaccharide (LPS) and lung specimens were taken 6 h or 24 h later.The accumulation and maturation status of pulmonary cDCs were assessed by flow cytometry.IL-6 and TNF-α were quantified to evaluate the lung inflammation.Transcription factors T-bet/GATA-3 mRNA ratio was determined to estimate the balance between Th1/Th2 responses.IFN-γand IL-4 were quantified to evaluate Thl-specific and Th2-specific cytokine production respectively.Lung injury was estimated by lung wet weight/body weight ratio (LWW/BW) and histopathological assessment.Comparison between groups was performed using one -way ANOVA.ResultsCompared with normal control group,LPS challenge resulted in higher level of IL-6 and TNF-α,increased LWW/BW ratio and significant histopathological changes (P ＜0.01 ).The accumulation and maturation of pulmonary cDCs in 6 h-ALI group were significantly increased after LPS challenge (P ＜0.01 ),while the accumulation and maturation of pulmonary cDCs in 24 h-ALI group were significantly lower than that in 6 h-ALI group ( P ＜0.01 ).Compared with normal control group,the expression of T-bet mRNA in 24 h-ALI group was markedly enhanced ( P ＜ 0.01 ) and the production of IFN-γ was increased as well ( P ＜ 0.01 ).ConclusionsThe accumulation and maturation of pulmonary cDCs peaked within 24 h after LPS challenge,pulmonary cDCs may initiate and amplify acute lung inflammation of ALI by enhancing the Th1 immune response and ensuing cytokine production.

Objective: To analyze the association of thrombocytosis with the prognosis of patients with gastric cancer.Methods: The clinical materials of 782 patients with gastric cancer who underwent initial surgery in our hospital between January 1995 and December 1999 were retrospectively analyzed.Kaplan- Meier and Log-Rank test were used to analyze the data.Prognostic factors were analyzed by multivariate Cox proportional hazards model.Results: Thrombocytosis oc-curred in 11.4% (87/782) patients.The platelet level was not significantly different among patients of different gender, tumor stage, and histological differentiation (P>0.05).However, a significant difference was observed in the platelet level among patients with different age and surgical approach (P<0.05).The 1-, 3-, and 5-year survival rates were 75.0%, 40.1% and 28.9% in patients without thrombocytosis and 52.8%, 16.9%, and 13.5% in patients with thrombocytosis (P=0.002).Univari-ate analysis showed that histological differentiation, pathological stage, surgical approach and thrombocytosis significantly affected the survival of patients.While age and gender had no significant impact on patient survival.Multivariate analysis showed that pathological stage, surgical approach, and thrombocytosis were independent prognostic factors for gastric can-cer.The relative risk of death of patients with thrombocytosis was elevated by 1.454 times (RR=1.454, 95% CI: 1.135～1.861, P=0.005).Conclusion: Thrombocytosis is an independent prognostic indicator for the survival of initially treated pa-tients with gastric cancer.

Background:Small intestinal bleeding is difficult to diagnose and treat because of its complex etiology and limit to examination method. Aims:To analyze the etiology,diagnosis,treatment and prognosis of small intestinal bleeding. Methods:The clinical data of 118 consecutive patients with small intestinal bleeding admitted from Oct. 2006 to Oct. 2016 at Daping Hospital,the Third Military Medical University were retrospectively analyzed. Results:Melena was the most common manifestation of small intestinal bleeding (41. 5％),followed by dark bloody stool,positive fecal occult blood test,hematochezia,and anemia with unknown cause. The major causes of bleeding were benign or malignant tumors (43. 2％),vascular lesions (28. 0％)and inflammatory lesions (15. 3％). Diagnosis was made by means of capsule endoscopy,colonoscopy,digital subtraction angiography (DSA),barium meal examination,multi-slice CT (MSCT)and CT enterography (CTE). Forty-one patients were treated by surgical operation,7 by selective arterial embolization,2 by endoscopic therapy,56 by conservative therapy,and all these patients achieved hemostasis. One patient died of massive hemorrhage and 11 were discharged with giving up of treatment. Conclusions:The leading cause of small intestinal bleeding is tumor,followed by vascular and inflammatory lesions. Capsule endoscopy is able to make definite diagnosis with high accuracy,and MSCT is the most widely used diagnostic approach. In addition to conventional treatment,surgical operation,interventional and endoscopic therapies also play important roles in treating small intestinal bleeding.

Objective To clarify the role of FLT3 signaling-dependent pulmonary conventional dendritic cells (cDCs) in the pathogenesis of lipopolysaccharide (LPS)-induced acute lung injury (ALI),and as well as the modulation effects of cDCs in vivo on the inflammatory responses to acute lung injury.Methods Thirty C57BL/6 male mice were divided into normal control group,LPS group,FLT3L pretreatment group,lestaurtinib,(a high efficient and specific blocker in FLT3 signal pathway) pretreatment group and vehicle (DMSD) control group.FLT3L and lestaurtinib were administrated subcutaneously for 5 days.Murine model of ALI was subsequently established by intra-tracheal application of LPS and lung specimens were harvested 6 h or 24 h later.The accumulation and maturation of pulmonary cDCs were assessed by flow cytometry.IL-6 and TNF-α were quantified to evaluate lung inflammation.Lung injury was estimated by lung wet weight/body weight ratio (LWW/BW) and histopathological assessment.Lung myeloperoxidase (MPO) activity was measured to evaluate neutrophil infiltration.Transcription factors Tbet/GATA-3 mRNA ratio was determined to estimate balance of Th1/Th2 response.IFN-γ and IL-4 were quantified to evaluate Th1-specific and Th2-specific cytokine production respectively.Results The accumulation and maturation of pulmonary cDCs peaked at 6h after LPS challenge.FLT3L pretreatment significantly stimulated the accumulation and maturation of pulmonary cDCs (P ＜ 0.05),leading to markedly deterioration of LWW/BW and lung histopathological changes.Meanwhile lung MPO activity and T-bet/GATA-3 mRNA ratio were elevated (P ＜ 0.05).Furthermore,the production of IL-6,TNF-α and IFN-γwas markedly increased by FLT3L pretreatment (P ＜ 0.05).In contrast,lestaurtinib pretreatment markedly inhibited the accumulation and maturation of pulmonary cDCs (P ＜ 0.05),leading to significant improvement of LWW/BW and lung histopathological changes.Meanwhile lung MPO activity and T-bet/ GATA-3 mRNA ratio were decreased (P ＜ 0.05).Furthermore lestaurtinib efficiently suppressed the production of IL-6,TNF-α and IFN-γ (P ＜ 0.05).Conclusion This study thus demonstrated that FLT3 signaling-dependent pulmonary cDCs could control the initiation of acute lung inflammation response to LPS-induced ALI through the regulation of neutrophil infiltration and balance of Thl/Th2 response.
