ABSTRACT
Objective To study the relationship between executive function and glial cell line-de-rived neurotrophic factor(GDNF) in patients with obsessive-compulsive disorder(OCD). Methods Totally 64 patients with OCD and 61 healthy controls were enrolled. The levels of serum GDNF were measured by en-zyme linked immunosorbent assay (ELISA). Wisconsin card sorting test (WCST) was used to assess the ex-ecutive function of the subjects. Yale-Brown obsessive compulsive scale ( Y-BOCS) was used to assess ob-sessive-compulsive symptoms. Results The patients with OCD(62. 67±8. 48)showed significantly poorer performance than healthy controls on the correct score of WCST(71. 16±7. 24)(P<0. 05),but the errors and non-persistent errors scores(52. 81±8. 39,31. 05±8. 46)were significantly higher than that in healthy con-trols (44. 79±7. 69,26. 57±7. 76)(P<0. 05). The level of serum GDNF in OCD group ((5. 64±1. 01) pg/ml)was significantly lower than that in control group ((6. 99±0. 94) pg/ml). There was a negative cor-relation between the number of non-persistent errors and the level of GDNF in OCD group( r=-0. 304,P=0. 015). The correct number and classification of WCST were negatively correlated with the scores of Y-BOCS(t=-0. 546,-0. 758,P<0. 05),the error of WCST were positively correlated to the scores of Y-BOCS(t=0. 616,P<0. 05). Conclusion These findings suggest that patients with OCD have executive dysfunction. The level of GDNF may be involved in the pathogenesis of OCD,which may be associated with the executive dysfunction in OCD patients.
ABSTRACT
Objective To describe the effects of surgical intervention on the prognosis in non-small-cell lung cancer patients with pleural carcinomatosis detected at thoracotomy.Methods Retrospectively analyzed clinical data from 54 patients who have unexpected malignant pleural nodules and/or malignant pleural effusions first detected at thoracotomy from January 2009 and December 2013.The effects of surgical intervention on the prognosis were also discussed.Results Sixteen cases had only biopsy,whereas 38 (70.4％) cases had primary tumor resection.The median survival time of 54 patients with pleural carcinomatosis were 23 months.The overall 1 and 5-year survival rates were 64％ and 18％,respectively.Primary tumor resection had significantly better outcome compared with biopsy(MST:respectively,24 vs 15 months,5-year survival rate 39％ vs 6％,P ＜0.05).Univariate analysis showed that primary tumor resection,no smoking history,lower T and N stage has favorable survival(P ＜ 0.05).Multivariate analysis showed that the best N stage(P =0.002) and adenocarcinoma(P =0.035) were favorable prognostic factors in these patients.Conclusion For patients with pleural careinomatosis first detected at thoracotomy,limited primary tumor resection may have survival benefits,lower T and N stage for them was associated with better survival.
ABSTRACT
Background:Oryz-Aspergillus Enzyme and Pancreatin Tablet is a double-deck digestive enzyme pellet containing Oryz-Aspergillus enzyme and pancreatin that has been widely used for treatment of functional dyspepsia (FD)in clinical practice. However,there is no randomized controlled trial focusing on the efficacy of this agent versus other drugs used for treatment of FD such as prokinetics and proton pump inhibitors (PPI). Aims:To compare the efficacy and safety among Oryz-Aspergillus Enzyme and Pancreatin Tablet,Domperidone Tablet and Esomeprazole Magnesium Enteric-coated Tablet, three drugs with different mechanisms of action on FD,in Chinese population. Methods:A total of 82 Helicobacter pylori-negative outpatients fulfilling the diagnostic criteria of FD in Rome Ⅲ were recruited from Nov. 2015 to Jun. 2016 at the First Affiliated Hospital of Zhejiang Chinese Medical University. These patients were randomly allocated into 3 groups,and received Oryz-Aspergillus Enzyme and Pancreatin Tablet (group A),Domperidone Tablet (group B)and Esomeprazole Magnesium Enteric-coated Tablet (group C)orally for 4 weeks,respectively. The improvement of dyspeptic symptoms and adverse events were observed and recorded. Results:After 4 weeks treatment,the overall efficacies for global symptoms in group A,group B and group C were 93. 1%,88. 9% and 69. 2%,respectively,statistically significant difference was existed among the three groups (P < 0. 05). Domperidone Tablet was effective for postprandial fullness and early satiety;Esomeprazole Magnesium Enteric-coated Tablet was sensitive for epigastric pain,epigastric burning,and belching and regurgitation;the efficacies of Oryz-Aspergillus Enzyme and Pancreatin Tablet for all five dyspeptic symptoms were in between. No adverse events were observed during treatment course. Conclusions:Digestive enzymes,prokinetics and PPI have different sensitive symptoms and optimal indications for treatment of FD. The overall efficacy of Oryz-Aspergillus Enzyme and Pancreatin Tablet is superior to that of prokinetics and PPI.

ABSTRACT
Objective To assess the diagnostic value of human epididymis secretory protein (HE4) versus CA125 for endometrial cancer.Methods Serum HE4 and CA125 levels were measured by enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immunoassay (ECLI) in 35 patients with endometrial cancer,48 patients with benign endometrial disorders and 40 healthy controls.The best cutoff value,sensitivity and specificity were calculated with pathological results as golden standard.Receiver operating characteristic curves were plotted,and areaunderthecurve (ROC-AUC) was used to compare diagnostic value of HE4 and CA125.Results The median value in HE4 in endometrial cancer were 51.46 pmol/L,which was significantly higher than in the healthy and benign disorder controls (25.65 pmol/L and 27.92 pmol/L).However,CA125 levels did not show statistically significant difference among the 3 groups.The ROC-AUC of HE4 for discriminating endometrial cancer between healthy controls and benign disorder controls were 0.922 and 0.759,respectively,which showed higher diagnostic value than CA125 (ROC-AUC of 0.590 and 0.457,respectively).HE4 had a specificity/sensitivity of 87.5％ /86.1％ for distinguishing healthy controls from endometrial cancer,and 95.5％ /50％ for differential diagnosis with benign disorders.Conclusions Measurement of HE4 can be used as a tumor marker for diagnosis of endometrial cancer.
ABSTRACT
Objective To compare the safety,feasibility,and long-term outcomes between combined thoracoscopic and laparoscopic esophagectomy (TLE) and open three-field esophagectomy (OE) for esophageal cancer.Methods The data of 183 patients with esophageal cancer who accepted TLE (n =94) or OE (n =89) from February 2009 to December 2011 were retrospectively collected and compared.Results Demographics,pathologic data in each cohort were almost identical.No significant differences were observed in operative time,the number of lymph node harvested,rates of anastomotic leak,thoracic abscess,chyle chest,re-operation,vocal cord paralysis,gastric emptying dysfunction and morbidity.A significant difference was observed in blood loss (86.6 ±38.3 ml in TLE group vs.217.4 ±87.2 ml in OE group,P=0.000),rate of transfusion (1.1％ vs.6.7％,P =0.045),hospital stay (13.9 ±7.5 d vs.17.1 ±10.2 d,P =0.017),rate of overall surgical complications (23.4％ vs.38.2％,P =0.030),rate of pulmonary complications (9.6％ vs.27.0％,P =0.002) and rate of arythmia (4.1％ vs.12.4％,P =0.046).Median follow-up time was 28.0 ±2.0 months (95％ CI:24.2-31.8).No difference between the two groups concerning survival was observed (P =0.954).Conclusion The TLE for esophageal cancer is safe and feasible.Although it cannot improve the survival of long-term,it is worth spreading in intraoperative and postoperative advantages compared with OE group.
ABSTRACT
Objective To investigate the relation of serum leptin level in senile depressive patients with type 2 diabetes and polymorphisms of leptin receptor gene 3057 G/A.Methods 10 senile depressive patients with type 2 diabetes and 47 senile depressive patients without type 2 diabetes were selected for the study.Leptin levels were determined by radioimmunoassay.Genomitic DNA were obtained by phenol/chloroform method.Leptin receptor gene 3057 G/A polymorphisms and allele frequencies were determined with the polymerase chain reaction and restricted fragment length polymorphism assay.Results (1) The differences of leptin receptor genotypes and allele distribution in the 3 groups were not found (all P ＞ 0.05).(2) Serum leptin level in senile depressive patients with type 2 diabetes and without type 2 diabetic patients ((41.65 ± 28.19) ng/ml,(25.56 ± 21.04) ng/ml) were significantly higher than the normal people ((10.84 ± 9.16) ng/ml) (all P ＜ 0.05).Serum leptin level in senile depressive patients with type 2 diabetes were significantly higher than without type 2 diabetic patients(P＜ 0.05).(3) The serum leptin level in genotype AA senile depressive patients with type 2 diabetes were significantly higher than genotype AA patients without type 2 diabetes.The differences of the serum leptin levels in genotype AA senile depressive patients without type 2 diabetes and genotype AG/GG patients without type 2 diabetes were not found(P ＞ 0.05).The differences of the serum leptin level in genotype AA and genotype AG/GG in normal groups were not found (P＞ 0.05).Conclusion Senile depressive patients have higher serum leptin level.The serum leptin level is higher,especially with type 2 diabetes.Serum leptin level is related to type 2 diabetes.Serum leptin level is not related to the polymorphisms of leptin receptor gene 3057 G/A.Type 2 diabetes are not related to polymorphisms of leptin receptor gene 3057 G/A.
ABSTRACT
Objective To detect eight kinds of clinical common pathogenic bacteria by DNA microarray.Methods Eight kinds of common pathogenic bacteria,including Staphylococcus aureus,Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli,Proteus mirabilis,Enterobacter aerogenes,Pseudomonas fluorescens,Shigella sonnei were collected.Universal primers were designed to amplify 16S rRNA gene fragment from the genomic DNA of the eight bacteria,and probes were designed in the highly variable regions.DNA microarray detection system was established and used for detection of colleted bacteria.A total of 50 samples were collected from the Zhongnan Hospital of Wuhan University,including 6 blood samples,32 sputum samples,9 feces samples and 3 bronchoscope lavage samples.DNA were extracted and detected by the established DNA microarray system.Results The desired fragments were well amplified by the self-designed universal primers.The selected probes had good detection results according to repeated detection.Of the 50 samples detected,pathgenic bacteria were accurately detected in 47 samples.Other three samples were not detected as those bacteria were not included in the chip.By optimizing the detection process,the results could be reported within 8 hours.Observation of probe signal attenuation indicated that even attenuated after 60 days,but the attenuation did not affect the results.Conclusion A microarray system was established for detection of clinical common bacteria accurately and quickly,which provided foundation for its clinical application.
