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 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.

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 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.

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 investigate the influence of chemotherapy on the phenotype of secreted protein, acidic and rich in cysteine (SPARC) in gastric cancer (GC). Methods:Immunohistochemistry was used to analyze SPARC expression in 132 GC patients. Among these patients, 54 with preoperative chemotherapy and 78 without preoperative chemotherapy were selected to analyze the effect of chemotherapy on SPARC phenotype by comparing the postoperative specimens of the two cohorts. Results:SPARC expression was higher in GC lesions than in the desmoplastic stroma surrounding the tumor cells and noncancerous tissues. High SPARC expression was related to invasion depth, lymph node metastasis, and TNM staging. SPARC expression was lower in patients with preoperative chemotherapy than in controls ( P<0.05). Gross type, histology, depth of invasion, lymph node metastasis, TNM staging, and SPARC phenotype correlated with the overall survival of the patients with preoperative chemotherapy. Further multivariate analysis suggested that lymph node metastasis, histology, and SPARC phenotype after chemotherapy were independent prognostic indicators of GC. Conclusion:SPARC expression was associated with invasion depth, lymph node metastasis, TNM staging and GC prognosis. Preoperative chemotherapy may change the phenotype of SPARC in GC patients.

AIM:To compare the reliability and plaque area between using high-cholesterol diet and high-cho-lesterol diet with corn oil to establish a rabbit atherosclerotic model .METHODS:Eighteen New Zealand rabbits were ran-domly divided into 3 groups (6 rabbits each):normal diet group (group C), high-cholesterol diet group (group H1) and high-cholesterol diet containing 6%corn oil group (group H2).All rabbits were fed for 12 weeks, and their body mea-sured was weighed at the end of every weeks .The serum levels of high-density lipoprotein cholesterol ( HDL-C) , low-den-sity lipoprotein cholesterol ( LDL-C) , total cholesterol ( TC) and triglyceride ( TG) were measured by automatic chemistry analyzer at 0 week and 12 weeks.At the end of 12 weeks, the thoracic aorta of 8-cm length since aortic root was isolated from the rabbit after anesthesia , and stained with Sudan IV or oil red O to verify the existence of plaque .The percentage of plaque area (PA/IA) in the intima area was further calculated by ImageJ 2x software.RESULTS:At the end of 12-week feeding, the serum levels of HDL-C, LDL-C and TC in both group H1 and group H2 were significantly higher than those in group C, and serum TG in group H2 was significantly higher than that in group C .Serum HDL-C in group H2 was signifi-cantly higher than that in group H1, but no significant difference of serum LDL-C, TC and TG between group H1 and group H2 was found .There was no plaque in the intima in group C , and plaques were observed in the intima of all rabbits in group H1 and group H2.Rabbit atherosclerotic models in both group H 1 and group H2 were established with a success rate of 100%.The values of PA/IA in group H1 [(49.74 ±18.78)%] and group H2 [(56.95 ±26.74)%] were both sig-nificantly higher than that in group C (0%), and no significant difference of PA/IA between group H1 and group H2 was observed.CONCLUSION:High-cholesterol diet with or without corn oil can establish a rabbit atherosclerotic model with a success rate of 100%after 12-week feeding , and the percentage of plaque area in the total aortic intimal area is not differ-ent in the 2 feeding methods .
