Objective: To explore the determinants for health-seeking behavior of the residents after cough for more than 3 weeks in Yiwu, Zhejiang Province, in order to provide reference for prevention and control of respiratory diseases. Methods: A multi-stage cluster random sampling method was used to recruit the community residents aged 5 years and above in Yiwu. A face-to-face questionnaire survey was conducted to collect demographic information, features of cough and health-seeking behaviors in the past month. The multivariate logistic regression model was employed to analyze the associated factors for health-seeking behavior after a cough for more than 3 weeks. Results: Among 6 374 residents investigated, 152 cases had a cough for more than 3 weeks in the past month, accounting for 2.48%. They were( 45.00±21.15 ) years old, including 70 ( 46.05% ) males and 82 ( 53.95% ) females. About 58.55% ( 89 ) of them sought medical treatment. The results of multivariate logistic regression analysis showed that females ( OR=2.100, 95%CI: 1.005-4.391 ), middle school education level ( OR=0.406, 95%CI: 0.168-0.983 ), family annual income of 100 000 to 199 999 yuan ( OR=2.993, 95%CI: 1.215-7.373 ) were associated factors for health-seeking behavior after a cough for more than 3 weeks. Conclusion The rate of health-seeking behavior after a cough for more than 3 weeks among the residents in Yiwu is 58.55%, which is associated with gender, education level and income.

Objective To compare and explore the impact of radical prostatectomy,external beam radiation therapy,and prostate brachytherapy on sexual function of patients with prostate cancer.Methods A total of 80 prostate cancer patients admitted to the Urology Department of Ji'an Central People's Hospital from January 2020 to December 2022 were retrospectively analyzed.According to the treatment plan,they were divided into a surgical resection group(n=26,underwent radical prostatectomy),an external beam irradiation group(n=28,treated with high-energy X-rays or particle beams directed at irradiate tumor cells from outside the body),and a brachytherapy group(n=26,radioactive material placed directly into the prostate to act on cancer cells).General data such as age,body mass index(BMI)and Gleason score were collected for all patients.Patients were assessed for erectile dysfunction using international index of erectile function(IIEF)scale,for sexual desire using sexual dysfunction index(SDI)scale,and for sexual function using male sexual health questionnaire(MSHQ)scale.Six months after the end of treatment,the patients'anxiety and depression were assessed using self-rating anxiety scale(SAS)and self-rating depression scale(SDS).Results There were no statistically significant differences in age,BMI and Gleason score among patients in each group(P>0.05).The brachytherapy group demonstrated a higher rate of no erectile dysfunction compared to surgical resection group and external beam radiation group(P<0.05),and lower rates of mild and moderate to severe erectile dysfunction compared to surgical resection group(P<0.05).The external beam irradiation group showed a higher rate of no erectile dysfunction and lower rates of moderate to severe erectile dysfunction compared to surgical resection group(P<0.05).The brachytherapy group showed higher scores in sexual fantasy,sexual desire,sexual frequency and total SDI score than those in surgical resection group and external beam radiation group(P<0.05).The external beam radiation group also had higher scores in these areas compared to surgical resection group(P<0.05).The total sexual function score was higher in brachytherapy group compared to the other two groups(P<0.05),and the external beam irradiation group had a higher sexual function score than surgical resection group(P<0.05).The SAS and SDS scores in brachytherapy group were lower than those in surgical resection group and external beam radiation group(P<0.05).Conclusion Among the treatment methods for prostate cancer,prostate brachytherapy is relatively more effective in maintaining sexual function,especially in terms of erectile function and sexual desire,outperforming radical prostatectomy and external beam therapy.

Objective The aim of our study was to investigate the influence of hexavalent chromium exposure on mRNA expression of cell cycle related genes in electroplating workers, and to provide population data for investigating the toxic mechanisms of hexavalent chromium. Methods A total of 155 cases of workers occupationally exposed to hexavalent chromium were selected, including 89 males and 66 females, and the average age of workers was 39.65±8.856 years old. Questionnaire was used to collect essential information of workers. Peripheral blood was collected from electroplating workers. The inductively couple plasma mass spectrometry (ICP-MAS) was used to measure total blood chromium content. The workers were divided into four groups according to the blood chromium content. After extracting total RNA from whole blood and reverse transcription, the mRNA expression levels of p16 and CDK6 genes were detected by real-time quantitative PCR. Meanwhile, the levels of blood chromium (BCr) and the mRNA expression of p16 and CDK6 genes were compared among four groups. The impact of BCr, smoking habits, drinking habits, gender on the mRNA expression of CDK6 gene was analyzed. Results The levels of BCr in group 1 to 4 were 0.04ppb, 0.47±0.29 ppb, 2.76±1.16 ppb, 9.36 ±4.38 ppb, respectively, and the difference between every two groups was significant (P<0.05) . The median of p16 gene expression in four groups was 4.22, 7.19, 7.47, and 14.60, respectively, and the difference between every two groups was not significant (P>0.05) . The mRNA expression levels of CDK6 gene in groups 2 to 4 were 15.05, 8.03 and 24.81, respectively, which were significantly higher than that in group 1 (P<0.05) . The results of logistic regression showed that the level of Bcr was the main influence factor, while smoking habits, drinking habits and gender had no obvious impact on the mRNA expression of CDK6 gene. Conclusions Long-term exposure of hexavalent chromium led to higher mRNA expression of CDK6 gene, and it may serve as a biomarker for workers occupationally exposed to hexavalent chromium.

BACKGROUNDAlthough three-dimensional MRI (3D-MRI) of short T1 inversion recovery turbo spin-echo (STIR TSE) has showed superior to two-dimensional MRI (2D-MRI) in showing the spinal cord and lumbar nerve roots, it remains difficult in demonstrating radicular vein at present. We have found that short T1 inversion recovery long time echo (STIR LONG TE) was better in showing radicular vein. To further study the methods and character of the 3D-MRI of lumbar nerve root, ganglions and radicular vein in normal and lumbar disc herniation (LDH) adults, in the present study, we evaluated two 3D-MRI techniques, STIR TSE and STIR LONG TE for demonstrating lumbar nerve roots and especial radicular vein in normal and LDH adults.

METHODSTwelve normal adult persons and 19 LDH patients were included in this study; special oblique coronal location was adopted. STIR TSE and STIR LONG TE were performed in all participants, and the detection rates of radicular vein and nerve root of L3, L4, L5, S1 were calculated. The grading system was used in grading compromise of the intraspinal extradural lumbar nerve root, ganglion and radicular vein in LDH patients, and all the grading injury of nerve root, ganglion and radicular vein had been evaluated.

RESULTSThe definite rate of radicular vein (DRRV) of 3D-MRI of STIR LONG TE was significantly different from that of STIR TSE. DRRV of STIR LONG TE was L3, 91.7%, L4, 100%, L5, 100%, S1, 100% and that of STIR TSE was L3, 33.3%, L4, 37.5%, L5, 58.3%, S1, 45.8% in normal adults. It showed no difference between STIR LONG TE and STIR TSE in the detection rate of nerve root. The different patho-injuries of nerve root, ganglion and radicular vein could be seen in all LDH patients by the 3D-MRI of STIR LONG TE. The mean score of Japanese Orthopaedic Association (JOA) was 16.16, and 29 nerve roots were calculated in all the study. The mean grading injury of nerve root was 2.17, that of nerve root ganglion was 1.28, that of radicular vein was 1.83, and the mean co-grading injury of nerve root, ganglion and radicular vein was 5.31. The correlation coefficient was 0.478 (P = 0.010) between the score of JOA and that of radicular vein.

CONCLUSIONThe 3D-MRI of STIR LONG TE is superior to STIR TSE for not only detecting the lumbar nerve root, ganglion and especial radicular vein in normal adults, but also displaying their patho-injuries degree in LDH patients.

OBJECTIVETo study whether 1.8 GHz microwaves (MW) (SAR, 3 W/kg) exposure can influence DNA damage induced by ultraviolet ray (UV).

METHODSThe lymphocytes were obtained from three young healthy donors. The cells were exposed to 254 nm UV at the doses of 0.25, 0.50, 0.75, 1.00, 1.50 and 2.00 J/m(2). The lymphocytes were also exposed to 1.8 GHz MW (SAR, 3 W/kg) for 0, 1.5 and 4.0 h. The combination exposure of UV plus MW was conducted. The treated cells were incubated for 0, 1.5 and 4.0 h. Finally, comet assay was used to detect DNA damage of above treated lymphocytes.

RESULTSThe difference of DNA damage induced between MW group and control group was not significant (P>0.05). the MTLs induced by UV were (1.71+/-0.09), (2.02+/-0.08), (2.27+/-0.17), (2.27+/-0.06), (2.25+/-0.12), (2.24+/-0.11)microm, respectively, which were significantly higher than that of control [(0.96+/-0.05) microm], (P<0.01). MTLs of some sub-groups in combination exposure groups at 1.5 h incubation were significantly lower than those of corresponding UV sub-groups (P<0.01 or P<0.05. However, MTLs of some sub-groups in combination exposure groups at 4.0 h incubation were significantly higher than those of corresponding UV sub-groups (P<0.01 or P<0.05).

CONCLUSIONThe exposure to 1.8 GHz (SAR, 3 W/kg) MW for 1.5 and 4.0 h can not enhance significantly human lymphocyte DNA damage. But MW can reduce or enhance DNA damage of lymphocytes induced by UV at 1.5 h and 4.0 h incubation in comet assay in vitro, respectively.

Background: Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of Chinese patients with esophageal cancer and the associated trends. Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 37 hospitals in 13 provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. For each esophageal cancer patient diagnosed between 2002 and 2011, clinical information and expense data were extracted by using structured questionnaires. All expense data were reported in Chinese Yuan (CNY; 1 CNY= 0.155 USD) based on the 2011 value and inflated using the year-specific health care consumer price index for China. Results: A total of 14,967 esophageal cancer patients were included in the analysis. It was estimated that the overall average expenditure per patient was 38,666 CNY, and an average annual increase of 6.27％ was observed from 2002 (25,111 CNY) to 2011 (46,124 CNY). The average expenditures were 34,460 CNY for stage Ⅰ, 39,302 CNY for stage Ⅱ, 40,353 CNY for stage Ⅲ, and 37,432 CNY for stage IV diseases (P < 0.01). The expenditure also differed by the therapy type, which was 38,492 CNY for surgery, 27,933 CNY for radiotherapy, and 27,805 CNY for chemotherapy (P < 0.05). Drugs contributed to 45.02％ of the overall expenditure. Conclusions: These conservative estimates suggested that medical expenditures for esophageal cancer in China substantially increased in the last 10 years, treatment for early-stage esophageal cancer costs less than that for advanced cases, and spending on drugs continued to account for a considerable proportion of the overall expenditure.

Objective To investigate the effects of asbestos exposure on plasma miRNA expression.Methods Plasma samples were collected from control group and asbestos -exposed group (time of exposure >10 years)and three samples from each group were selected to detect differentially expressed miRNA using LC Sciences miRNA Microarray -Single.The target genes of differential miRNA were predicted by three kinds of online software,Target Scan,miRanda and PicTar.GO term enrichment and KEGG pathways were analyzed.Results The results of microarray indicated that there were 40 differential miRNA expression between exposed and control groups(P <0.05),and the signal value of 9 differential miRNA exceeded 500.After analyzing signal pathways of target genes of 5 miRNA,of which the signal values were over 500,these target genes were found mainly involved in pathways associated with cancer and metabolism,including potential function targets of FAS,TP53 and FGFR3.Conclusion Asbestos exposure can result in differentially expressed miRNA in the plasma from workers occupationally exposed to asbestos and the target genes of these miRNA may play important roles in the pathways of cancer.However,the mechanism of these miRNA in asbestos -related diseases needs to be further studied in the future.
