Objective: To study the relationship between the whole blood zinc concentration and prostate carcinoma and to explore the diagnostic value of the whole blood zinc concentration combined with blood serum prostate specific antigen (PSA) for prostate cancer. Methods: A total of 95 patients with prostate carcinoma and 91 patients with benign prostate hyperplasia were selected between July 2005 and October 2008 in Zhongda Hospital of Southeast University and The Affiliated Drum Tower Hospital of Nanjing University Medical School. The whole blood zinc concentration was analyzed by atomic absorption spectometry. The serum PSA was analyzed by radioimmunoassay. Results: The volumes of the whole blood zinc concentration were 4.73±1.51 μg/mL in the prostate carcinoma group and 6.82±1.63 μg/mL in the benign prostate hyperplasia group, with a significant difference between the two groups (P＜0.001). The serum PSA general distribution was significantly different between the two groups (P＜0.01). There was no significant difference in the serum PSA of 4.0 to 10.0 ng/mL between the two groups (P=0.14). Compared with that in the benign prostate hyperplasia group, the area under ROC curve for the whole blood zinc concentration in the prostate carcinoma group was 0.82. The diagnostic accuracy was optimal with 5.24μg/mL set as the cut-off value of the whole blood zinc concentration and the Youden's index was 0.46 when it was combined with serum PSA 4.0 ng/mL (connection in series). The specificity was 75%, up to 2.34 times of serum PSA applied alone. Meanwhile, the Youden's index was 0.51, achieving 2.22 times. It was not helpful for the diagnosis of prostate carcinoma that the two diagnostic tools were in parallel by which the Youden's index was only 0.14. Conclusion: Detection of the whole blood zinc concentration is beneficial for differentiation of prostate carcinoma from benign prostate hyperplasia. Combined with serum PSA (connection in series), it can significantly impove diagnostic efficiency when PSA was 4.0～10.0ng/mL. Detection of the whole blood zinc concentration can provide valuable information for the diagnosis of prostate cancer and worths clincal application.

Objective To explore the influence of epithelial mesenchymal transition(EMT)in radiosensi-tivity of EGFR-mutant NSCLC cell with acquired resistance to EGFR-TKI. Methods In this study,EGFR-mutant human lung adenocarcinoma cell line PC-9 and Gefitinib acquired resistance cell line PC-9/AB were used. Western blot was used to assess EMT. Wound healing migration assay was tested. CCK8,colony formation and flow cytome-try were used to evaluate survival fraction ,as the sensitivity to irradiation. Results PC-9/AB displayed radioresis-tance(P<0.05). When EMT was reversed with CDH1,its radiosensitivity was significantly higher than PC-9/AB (P < 0.05). PC-9/TGF also displayed radioresistance (P < 0.05),as well as EMT phenotype presented. Conclusion EMT enhanced the radioresistance of EGFR-mutant NSCLC cell with acquired resistance to EGFR-TKI, possibly through TGF-βpathway.

Objective To investigate the clinical efficacy of enhanced recovery after surgery (ERAS) in the radical gastrectomy for gastric cancer.Methods The clinical data of 140 patients undergoing radical gastrectomy for gastric cancer at the Affiliated Hospital of Qingdao University from April 2011 to June 2013 were prospectively analyzed.A double-blind,randomized,controlled study was performed in the 140 patients,and all of them were divided into the ERAS group (patients undergoing perioperative management according to enhanced recovery rehabilitation program) and the control group (patients undergoing perioperative management) based on a random numble table.The inflammatory markers,nutritional index and postoperative recovery of patients were observed.Patients of the ERAS group were followed up by telephone interview within the first 24 hours after discharge,and by outpatient examination since the second week after discharge.The follow-up was ended at postoperative day 30.Patients of the control group were reexamined at the third week after discharge.The measurement data with normal distribution was presented as x ± s.The comparison between groups was evaluated with an independent sample t test.The trend analyses for variables were done using repeated measures ANOVA.The count data were analyzed using the chi-square test or Fisher exact probability.Results Eighty patients were screened for eligibility,and were allocated into the ERAS group (40 patients) and the control group (40 patients).The total protein in serum (TP),albumin (Alb),prealbumin,TNF-α,IL-6,c-reactive protein,resting energy expenditure (REE),glycemic index,insulin index and Insulin resistance index in the 2 groups showed a range of variations at postoperative day 1,3,and 5,and these were (61 ±5)g/L,(34 ±3)g/L,(160 ± 18)g/L,(12.3 ±2.3)mmol/L,(101 ±34)ng/L,(43 ± 11)g/L,(1 336 ± 105)kal/d,(7.6 ±0.8)mmol/L,(16.8 ±3.5)mU/L and 5.7 ±1.3 in the ERAS group at postoperative day 1,and (58 ± 4) g/L,(31 ± 4) g/L,(147 ± 18) g/L,(15.3 ± 2.2) mmol/L,(122 ±37)ng/L,(56 ±27) g/L,(1 450 ± 164)kal/d,(9.3 ± 1.4) mmol/L,(30.5 ±6.8) mU/L and 12.5 ±3.2 in the control group,respectively,showing a significant difference between the 2 groups (F =31.63,8.03,67.36,147.04,9.63,6.84,16.10,54.85,104.51,139.47,P ＜0.05).The duration of fever,time to flatus,duration of hospital stay,hospital expenses,numeric rating scale and quality of life (QOL) were (2.9 ±0.9) days,(2.9 ± 0.6) days,(7.6 ± 2.1) days,(28 495 ± 4 722) yuan,1.4 ± 1.0 and 15.4 ± 0.9 in the ERAS group after operation,and (3.8 ±0.6)days,(3.5 ±0.7)days,(8.9 ±2.6)days,(35 318 ±7 610)yuan,2.4 ± 1.1 and 14.4 ± 1.2 in the control group,respectively,with a significant difference between the 2 groups (t =-0.91,-3.66,-2.85,-4.82,-4.20,3.92,P ＜0.05).Two patients were complicated with respiratory diseases,1 patient received reoperation and 1 was readmitted to the hospital at postoperative day 30 in the ERAS group.Three patients had respiratory diseases,1 received reoperation and 2 were readmitted to the hospital at postoperative day 30 in the control group,with no significant difference between the 2 groups (P ＞ 0.05).Conclusions ERAS is safe and feasible for the perioperative treatment of patients with gastric cancer,meanwhile it could reduce the surgical stress,shorten the duration of hospital stay and improve QOL and postoperative complications,ERAS might take effects by reducing insulin resistance and decreasing REE.Registry This study was registered with the Chinese Clinical Trial Registry with the registry number of ChiCTR-TRC-10001611.

Objective To analyze the epidemiology and clinical features of the critical congenital heart diseases in neonates,and to summarize the main points on pre-operative treatments.Methods We retrospectively analyzed all critical congenital heart disease in newborns admitted to CICU from June 2014to June 2015.Depict entity distribution,the main symptoms,and the key points on their treatments,also the indi-cation of intubation and their operation time were summarized.Results In totally 96cases,transposition of the great artery,with and without the intact ventricle septum,was the biggest category and counts for 49%in our group.Severe cyanosis was the main symptom for 62.5% of all cases.Another key symptom was the heart failure(33.3%).Eight-seven cases were intubated during their treatments,in which 41were intubated as soon as they were admitted and 40cases were done in the first 24hours after their admission.One case died before treatment due to interrupted aortic arch.All the rest received operations during their hospital stay. Conclusion Transposition of great artery is the dominating entity in critical congenital heart diseases in new-borns;severe cyanosis is the main symptom.Treatment should be based on each characteristic anatomy and hemodynamics features.Rigorous and dynamic monitoring on the homeostasis and metabolic index determines the indication of intubation and surgery time.

Objective : To investigate the current status of hearing loss in a fastener manufacturing enterprise, and to analyze its influencing factors, so as to provide insights into occupational disease prevention and control. Methods: The occupational health examination data of noise exposed workers and the workplace occupational disease hazard factors detection data in a fastener manufacturing enterprise in Jiaxing City in 2022 were collected through the Occupational Disease and Occupational Health Hazard Factors Detection System of China Disease Prevention and Control Information System, and factors affecting the development of high-frequency noise-induced hearing loss (HFNIHL) and speech-frequency noise-induced hearing loss (SFNIHL) were analyzed. Results: Totally 625 workers were investigated, with a median age of 44.00 (interquartile range, 13.00) years and a median length of service of 8.00 (interquartile range, 9.00) years, and including 519 men (83.04%) and 106 women (16.96%). There were 309 workers with single noise exposure (49.44%) and 316 workers with joint noise exposure (50.56%), and 518 workers exposed to noise with the normalized continuous A-weighted sound pressure level equivalent to a 40 h working week (LEX,40 h) that exceeded the national standard (82.88%). The detection rates of HFNIHL and SFNIHL were 49.12% and 35.04%, respectively. Multivariable logistic regression analysis indicated that males (OR=10.528, 95%CI: 5.271-21.025), length of service of 10 years and longer (OR=2.451, 95%CI: 1.599-3.759), LEX,40 h of >85 dB (A) (OR=2.227, 95%CI: 1.318-3.764) and joint noise exposure (OR=3.002, 95%CI: 2.080-4.334) were associated with an increased risk of HFNIHL, and male (OR=9.400, 95%CI: 4.211-20.985), LEX,40 h of >85 dB (A) (OR=2.305, 95%CI: 1.345-3.951), and joint noise exposure (OR=3.880, 95%CI: 2.677-5.623) were associated with an increased risk of SFNIHL. Conclusion Gender, length of service, noise intensity and exposure mode are factors affecting the risk of HFNIHL, while gender, noise intensity and exposure mode are factors affecting the risk of SFNIHL.

Objective To screen the active tuberculosis patients among HIV infected patients,and investigate the diagnostic methods for active tuberculosis among TB/HIV co-infected patients.Methods From August 2006 to March 2007,660 HIV/AIDS patients were enrolled.The study was conducted at 4 authorized hospitals for AIDS in Nanning and Liuzhou.Chest X-ray(CXR),acid-fast stain test of sputum smear and fast culture were applied if CD+4 T cell counts were below 350 cells/mm3 or the patients at least have one suspected symptom.Result The CD<;+>4 T cell count in 76.1% (502/660) of the patients was less than 200 cells/mm3.TB/HIV coinfection was found in 22.9% (151/660) of the HIV patients.Among them,74.8% (113/151) of them were pulmonary TB patients.One third of them were extra-pulmonary TB patients,and 68.1% of them involved lymph node.In 264 patients with negative sputum smear test and CXR,20.1% (53/264) of them showed positive results in fast culture tests.In addition,the non-tuberculosis mycobacterium (NTM) infection accounted for 38.5% culture positive cases.Conclusions The TB/HIV coinfection rate is 22.8%.Liquid rapid culture of sputum plays an import role in diagnosing of active tuberculosis among HIV patients.There are considerable proportions of NTM or extra-pulmonary TB coinfection in HIV patients.
