PurposeIt is well known hypobaric hypoxia occurs with acute exposure to high altitude, with commonly associated change of cerebral blood flow (CBF). In this work, three-dimensional arterial spin-labeling (3D ASL) was used to monitor the change of CBF to further extend our understanding of hypobaric hypoxia.Materials and Methods Six healthy subjects were recruited for this study, they were asked to stay at high altitude areas for 5 days, and then returned to the plain. All subjects received MRI examination in both plain and high altitude areas using exactly the same 3.0T MR scanner. A total of 8 MR scans were performed, and all the parameters were kept the same, the changes of cerebral blood flow were observed.ResultsCBF increased obviously and reached its peak after acute exposure to high altitude, at the first day at high altitude, CBF measurements in global brain, grey matter and white matter increased signiifcantly compared to the plain, the difference was statistically significant (P<0.05); after that, the CBF measurements started to gradually decrease in the second day and a small climb on the third day at high altitude, then the CBF continued to drop after returning to sea level, even below that at sea level prior to departure. After 1 week back to the plain area, CBF measurements in global brain, grey matter and white matter were still lower than those before departure for high altitude areas, with a statistically signiifcant difference (P<0.05).ConclusionCBF measurements had obvious increase upon initial arrival at high altitude, and then the CBF continued to drop even below that at sea level prior to departure.

Objective To compare the effects of different intervention methods on relieving the xerostomia and to explore the best method to relieve xerostomia in patients during anesthesia recovery period.Methods A total of 108 patients in post anesthesia care unit after general anesthesia were recruited from March 2015 to June 2016 in Chinese PLA General Hospital.They were randomly divided into the experimental group 1 (27 cases),experimental group 2 (26 cases),condition conditional group (28 cases),blank control group (27 cases) with different methods of moistening oral cavity after extubation with 2 ml at a time for every 10 minutes including lemon water sprayer,vitamin C sprayer,warm water sprayer and non-intervention.And then,the visual analogue scale (VAS) for the intensity of xerostomia and the prevalence of adverse reactions including nausea,vomiting,abdominal pain,abdominal distension and so on were compared before intervention,20 minutes and 50 minutes after intervention.Results The results showed that the scores of VAS in the experimental group 1 were lower than those in the experimental group 2,the conditional control group and the blank control group 20 minutes and 50 minutes after intervention with significant differences [(Dunnett-t =-1.200,-1.733,-1.733;P＜ 0.01;20 minutes after intervention),(Dunnett-t =-2.150,-2.500,-5.567;P＜0.01;50minutes after intervention)].Conclusions The application of the lemon water sprayer for moistening oral cavity can effectively relieve the xerostomia in patients during anesthesia recovery period.Besides,the effects of the lemon water sprayer are better than those of vitamin C sprayer and warm water sprayer.

Objective To assess the effectiveness of a novel mobile health patient management system involving doctors, nurses, and patients ( TRIO mode) on glycemic control and self-monitoring of blood glucose (SMBG) compliance among the type 2 diabetes mellitus ( T2DM) patients using basal insulin standardization treatment in China. Methods From April 2014 to April 2015, 416 hospitals in 110 cities of 30 provinces, municipalities, and autonomous regions across China were selected to participate in the program. A Online-to-Offline ( O2O) integrated mobile health patients management system with mobile terminals for the doctors, nurses, and patients was applied in the program for patient education, follow-up, and data collection. For all the newly recruited patients, the baseline information was collected and a first-day patient education program were provided by a designated nurse. In the 12-week follow-up period, data of basal insulin doses and fasting plasma glucose ( FPG) values were collected from the patients by text messages or tracking phone call by the nurse. The patients also received timely standardized patients health education and glycemic control guidance by participating in thepatient education forum anddoctors' hotline in order to help them achieve the glycemic control goals. Results A total of 102 524 patients using basal insulin treatment were eligible and enrolled in the program. 64 420 patients completed the 12 weeks follow-up and provided at least one FPG value at all five follow-ups. In total, 62. 6% (40 334 / 64 420) of the patients reached the FPG control target(FPG≤7. 0 mmol/ L) at the end of follow-up period. The weekly average FPG for patients with complete SMBG data decreased from 10. 58 mmol/ L to 6. 91 mmol/ L while the FPG control rates increased from 13. 4% to 69. 2% . The weekly average FPG for the patients provided incomplete SMBG data decreased from 10. 54 mmol/ L to 7. 13 mmol/ L while the FPG control rates increased from 13. 6% to 62. 2% . The FPG control rates for the patients provided complete SMBG were 1. 74 times higher than those patients provided incomplete SMBG. Based on a GEE model, the average decline of the FPG and the increase of the FPG control rates were significantly better for patients who provided complete SMBG as compared to the patients with incomplete SMBG data. The results of the multivariate logistic regression analysis showed that factors such as receiving the first-day education, participating in the follow-up patient education forum, and the doctors' hotline were significantly associated with the improvement of the SMBG compliance, the treatment adherence, and the FPG control rates. The SMBG compliance and the treatment adherence for patients who completed first-day education were 1. 68 times and 1. 22 times higher, respectively. For the patients who participated in follow-up education activities, their SMBG compliance and treatment adherence were 3. 17 times and 3. 36 times higher, respectively. Conclusion The innovativeTRIOmobile health patient management mode was feasible and effective for better managing the type 2 diabetes patients initiated on basal insulin treatment in China. Active participation in the first-day education program and the follow-up patient education activities can effectively improve the SMBG compliance and the treatment adherence, and therefore play an important role in helping patient achieving FPG control in a faster manner.

Objective:To conduct Meta-analysis of the effectiveness of improved activity mode in prevention of peripherally inserted central catheter (PICC) related thrombosis in tumor patients.Methods:PubMed, The Cochrane Library, CNKI, Wanfang Database and VIP database were conducted computer retrieval of studies on improved activity mode and PICC related thrombosis in tumor patients from January 1, 2010 to December 31, 2019. A total of two researchers independently screened literature, extracted data and evaluated the quality of literature. The RevMan 5.3 software was used for Meta-analysis of the included studies.Results:A total of 7 randomized controlled trials (RCT) were included in this study. Meta-analysis results showed that compared with the conventional catheterization side upper limb exercise group, the incidence of catheter-related venous thrombosis in tumor patients in the improved activity mode group was reduced ( OR=0.22, 95% CI=0.13-0.38, P<0.01) , and the maximum blood flow velocity of the axillary vein was increased ( MD=1.03, 95% CI=0.64-1.42, P<0.01) . Conclusions:Improved activities on the limb of catheterization can effectively accelerate the blood flow velocity of the axillary vein after PICC catheterization in tumor patients and reduce the occurrence of catheter-related venous thrombosis.

Purpose To establish a non-invasive model for predicting axillary lymph node metastasis(ALNM)based on breast cancer related metabolic parameters.Materials and Methods A total of 158 patients diagnosed as breast cancer in Meizhou People's Hospital from January 1,2016 to March 30,2023 were selected,and all of them underwent whole-body PET/CT examination in our department before operation.Metabolic parameters of primary breast cancer[maximum standard uptake value(SUVmax),metabolic volume,total glycolysis(TLG)],highest axillary lymph node uptake SUVmax(SUVmaxALN),axillary lymph node short diameter and clinical related indexes[age,maximum tumor diameter,pathological type and tumor location]were obtained.According to the surgical and pathological results,the patients were divided into ALNM positive[ALNM(+)]group and ALNM negative[ALNM(-)]group.The relationship between the parameters of the two groups was analyzed,the best influencing factors were screened out,and binary Logistic regression was used to establish a prediction model to obtain the primary metabolic parameters of breast cancer.Results There were significant differences in TLG,metabolic volume,axillary lymph node short diameter and SUVmaxALN between ALNM(+)group and ALNM(-)group(Z=-3.924--1.812,all P<0.05),but there were no significant differences in age,tumor maximum diameter,pathological type,tumor location,primary focus SUVmax and SUVavg(all P>0.05).Multivariate Logistic regression analysis showed that TLG of breast cancer primary focus and SUVmaxALN could be used as independent risk factors of ALNM of breast cancer,and the regression model established by using these two factors was Logit(P)=0.142+0.443×SUVmaxALN-0.013×TLG.The area under the curve of ALNM prediction model based on TLG and SUVmaxALN was 0.769(95%CI 0.691-0.841,P<0.001).Conclusion TLG of breast cancer primary focus and SUVmaxALN can be used as independent predictors of ALNM of breast cancer,and the prediction model based on these two factors can predict ALNM well.This non-invasive method may have a certain application prospect in clinic.

Shengmai Yin (SMY) is a Chinese herbal decoction that effectively alleviates the side effects of radio-therapy in various cancers and helps achieve radiotherapy's clinical efficacy.In this study,we explored the interaction mechanism among SMY,DNA methylation,and nasopharyngeal carcinoma (NPC).We identified differences in DNA methylation levels in NPC CNE-2 cells and its radioresistant cells (CNE-2R)using the methylated DNA immunoprecipitation array and found that CNE-2R cells showed genome-wide changes in methylation status towards a state of hypomethylation.SMY may restore its original DNA methylation status,and thus,enhance radiosensitivity.Furthermore,we confirmed that the dif-ferential gene Tenascin-C (TNC) was overexpressed in CNE-2R cells and that SMY downregulated TNC expression.This downregulation of TNC inhibited NPC cell radiation resistance,migration,and invasion.Furthermore,we found that TNC was hypomethylated in CNE-2R cells and partially restored to a hypermethylated state after SMY intervention.DNA methyltransferases 3a may be the key protein in DNA methylation of TNC.

Objective To observe the effect of arsenic exposure to drinking water on thelevel of histone 3 lysine 4 trimethylation (H3K4me3) and histone 3 lysine 79 trimethylation (H3K79me3) in peripheral blood leukocytes of human,and to analyze the relationship between arsenic exposure and H3K4me3,H3K79me3 modification levels.Methods A cluster sampling survey was carried out in typical endemic arsenicosis areas of Shanxi and Jilin provinces.Two hundred eighty-one local residents with a drinking water age of ≥ 10 years were selected as the survey subjects.According to the arsenic content of drinking water,the tested population was divided into control group (water arsenic content ≤0.01 mg/L,60 cases),low water arsenic exposure group (＞ 0.01-0.05 mg/L,61 cases),medium water arsenic exposure group (＞ 0.05-0.10 mg/L,50 cases),and 110 cases of high water arsenic exposure group (＞ 0.10 mg/L).Drinking water samples,immediate urine samples and peripheral blood samples were collected from the subjects.Arsenic content in drinking water and urinary arsenic content were determined via the atomic fluorescence method;histone H3K4me3 and H3K79me3 in peripheral blood leukocytes were determined by dot blot hybridization (Dot Blotting).Results There were no statistically significant differences in age (61.50,60.00,59.50,59.50 years old),different gender (male:20,27,17,40 cases,female:40,34,33,70 cases),body mass index (BMI),smoking and drinking status between the control group,low,medium and high water arsenic exposure groups.Water arsenic content in the control group,low,medium and high water arsenic exposure groups (median:0.005,0.024,0.076,0.150 mg/L),urinary arsenic content (0.011,0.018,0.061,0.134 mg/L),and water arsenic cumulative exposure levels (0.342,1.641,5.273,7.716 mg) were compared between groups,the differences were statistically significant (H =256.041,88.615,218.610,P ＜ 0.01).In the control group,low,medium and high water arsenic exposure groups,the modification levels of H3K4me3 (0.100,0.059,0.083,0.083)and H3K79me3 (0.049,0.036,0.055,0.052) in peripheral blood leukocytes were not significantly different (H =1.488,2.097,P ＞ 0.05).The levels of H3K4me3 and H3K79me3 in peripheral blood leukocytes were positively correlated with water arsenic content,urinary arsenic content,water arsenic cumulative exposure levels (r =0.245,0.221;0.299,0.318;0.149,0.149;P ＜ 0.01 or ＜ 0.05);there was a positive correlation between H3K4me3 and H3K79me3 modification levels (r =0.811,P ＜ 0.01).Conclusion There is a positive correlation between arsenic exposure through drinking water and the levels of H3K4me3 and H3K79me3 in the peripheral blood leukocytes of the population,but it is necessary to expand the sample size for further study.

Objective:To explore the occupational stress status and influencing factors of workers in a textile factory in Zhejiang Provice.Methods:In October 2018, 505 workers from a textile factory in Zhejiang Province were selected as research objects by convenient sampling method. A total of 505 questionnaires were distributed, 495 of which were effective and the effective recovery rate was 98.0%. Job Content Questionnaire (JCQ) and Effort Reward Imbalance Questionnaire (REI) were used to investigate textile workers' occupational stress and analyze its influencing factors. The differences of the composition ratio of different groups were tested by χ 2 test. The influencing factors such as age, gender and occupation on occupational stress were analyzed by multivariate logistic regression. Results:ERI analysis results showed that the high and low occupational stress accounted for 30.1% and 69.9%, respectively. The differences of occupational stress among workers of different job types and working ages were statistically significant ( P<0.05) . The detection rates of high occupational stress of paper workers and spinners were 47.8% (11/23) and 44.8% (30/67) , respectively, higher than other jobs. The detection rate of high occupational stress for workers with more than 5 years of service was 46.4% (13/28) . The results of JCQ analysis showed that there was no statistical significance in the differences of daily working hours and length of service between different gender, education levels, types of work patterns, and occupational stress ( P>0.05) . Job types had significant effects on the occupational stress defined by ERI ( P<0.05) , the risk of occupational stress was 2.151 times than that of the coiler. Conclusion:There are significant differences in occupational stress risk among workers of different types of work in textile industry, so different measures should be taken to prevent and control occupational stress in different jobs.
