Objective To investigate the activity concentrations of natural radionuclides in drinking water (tap water and well water) in urban and rural areas of Hohhot, assess the safety of drinking water, and to provide data support for local drinking water radioactivity monitoring and management. Methods Representative samples of well water and tap water were collected from nine banners/counties/districts in Hohhot. Activity concentrations were measured using a low-background gross α/β counter, an α spectrometer, inductively coupled plasma mass spectrometry, and a radium/radon analyzer. Results A total of nine tap water samples and nine well water samples were analyzed. For the tap water samples, gross α activity concentrations ranged from 0.093 to 0.193 Bq/L, gross β from 0.091 to 0.225 Bq/L, uranium mass concentrations from 2.32 to 10.36 μg/L, thorium mass concentrations from 0.09 to 0.20 μg/L,²¹⁰Po activity concentrations from below the minimum detectable limit to 0.41 mBq/L, and ²²⁶Ra activity concentrations from 8.70 to 13.35 mBq/L. For the well water samples, gross α activity concentrations ranged from 0.111 to 0.203 Bq/L, gross β from 0.111 to 0.270 Bq/L, uranium mass concentrations from 2.31 to 13.28 μg/L, thorium mass concentrations from 0.17 to 0.26 μg/L,²¹⁰Po activity concentrations from 1.03 to 2.12 mBq/L, and ²²⁶Ra activity concentrations from 15.38 to 23.63 mBq/L. Conclusion The activity concentrations of natural radionuclides in both well water and tap water in the Hohhot region were at environmental background levels and met national drinking water hygiene standards.

Objective A joint Poisson-logistic model in a Bayesian framework is proposed to constructed using tuberculosis(TB)reporting data from 14 prefectures in Xinjiang from 2014 to 2020 in combination with relevant social,economic,and environmental factors affecting the reported incidence rate of TB to explore potential underreporting areas of the TB reporting data,and to provide a strong evidence－based support for the subsequent decision－making on the precision prevention and control of TB.Methods Relevant factors affecting the reporting process and disease process of TB were collected,and important covariates were screened for inclusion in the model using the factor detector in the Geo-detector method,and the reported incidence model of TB and the expected incidence model of TB in Xinjiang were constructed separately,which together constituted a hybrid model of underreporting of TB(Poisson-logistic joint model).The mixed model was used to estimate the risk of TB underreporting in each prefecture of Xinjiang,and to explore the regional distribution of the potential risk of TB underreporting.Results Factor detector result pairs showed that GDP per capita was associated with the largest contribution to the risk of TB underreporting(0.5481);goodness－of－fit test showed that the data were well fitted(Bayesian P－value<0.001),and the Bayesian Poisson-logistic joint model could be applied to the study of the risk of underreporting of TB reporting data in Xinjiang from 2014 to 2020.The results showed that the risk of underreporting of TB The risk of underreporting of reported data was concentrated in the four southern Xinjiang prefectures,with the greatest risk of underreporting of TB reported data in Kashgar 0.1426(0.1403,0.1445).The lower risk of underreporting was concentrated in the eastern and central parts of Xinjiang,with the lowest risk of underreporting in the city of Karamay[0.1017(0.9983,0.1034)].In a joint Bayesian Poisson-logistic model,it was found that population density(IRR＝1.0060,95%CI:1.0059~1.0061)and average annual temperature(IRR＝1.0087,95%CI:1.0086~1.0088)were risk factors for underreporting of TB,and GDP per capita(IRR＝0.9385,95%CI:0.9365~0.9394)and an increase in the number of registered nurses(IRR＝0.9916,95%CI:0.9913 to 0.9920)reduced the risk of TB underreporting.Conclusion The Bayesian Poisson-logistic joint model estimated the potential incidence of TB in Xinjiang Uygur Autonomous Region and revealed significant discrepancies between reported and true TB incidence rates.It identified underreporting trends and localized potential underreporting risk areas,providing a theoretical basis for tailored and precise TB prevention and control strategies in Xinjiang.

Objective:To investigate the effect of preoperative continuous fascia iliaca compartment block (FICB) on perioperative opioids dosage and quality of postoperative recovery in elderly patients with frail.Methods:A prospective study method was used. Sixty elderly frail patients underwent selective unilateral femoral head replacement surgery from November 2022 to October 2024 in Sihui People′s Hospital were selected. The patients were divided into control group and FICB group by random digits table method with 30 cases each. The patients in control group did not receive continuous FICB before surgery, and the patients in FICB group received continuous FICB 1 d before surgery. The perioperative use of opioids and analgesic effect, operative time, intraoperative blood loss, postoperative hospital stay, quality of recovery-40 (QoR-40) score at discharge and postoperative complications were compared between the two groups.Results:A total of 57 patients completed the study, with 29 cases in the FICB group and 28 cases in the control group. There were no statistical differences in operative time, intraoperative blood loss and postoperative hospital stay between the two groups ( P>0.05). The sufentanil dosage of patient-controlled analgesia (PCA), perioperative nalbuphine dosage, frequency of perioperative visual analog score (VAS)>4 scores, rate of preoperative rescue analgesia, rate of postoperative rescue analgesia and pressing frequency of PCA in FICB group were significantly lower than those in control group: (94.1 ± 5.4) μg vs. (102.1 ± 6.1) μg, 0 (0, 0) mg vs. 10.0 (0, 20.0) mg, 3.0 (2.0, 5.0) times vs. 5.0 (4.0, 6.0) times, 3.4% (1/29) vs. 32.1% (9/28), 13.8% (4/29) vs. 39.3% (11/28) and 2.0 (1.0, 3.0) times vs. 4.0 (3.0, 5.0) times, and there were statistical differences ( P<0.01 or <0.05). The total QoR-40 score and physical comfort, pain scores in FICB group were significantly higher than those in control group: 156(153, 161) scores vs. 153 (148, 159) scores, 47 (45, 50) scores vs. 45 (43, 47) scores and 30 (29, 31) scores vs. 28 (25, 30) scores, and there were statistical differences ( P<0.05 or <0.01); there were no statistical differences in emotional state, physical independence and psychological support scores between the two groups ( P>0.05). The incidences of dizziness and nausea vomiting in FICB group were significantly lower than those in control group: 13.8% (4/29) vs. 42.9% (12/28) and 10.3% (3/29) vs. 35.7% (10/28), and there were statistical differences ( P<0.05); there were no statistical difference in the incidences of delirium, pulmonary infection and deep vein thrombosis in the lower extremities between the two groups ( P>0.05). Conclusions:Preoperative continuous FICB can reduce perioperative opioids dosage in elderly patients with frail, and improve early stage postoperative recovery quality.

AIM:To investigate the effect of dyes,Remazol BrOrange yellow(RBY)and erythrosine(ERY),on the outcomes of immunoblotting analysis when used for staining the concentrate gel in sodium dodecyl sulfate-polyacryl-amide gel electrophoresis(SDS-PAGE).METHODS:Polyacrylamide gels were divided into five groups:the control group(prepared according to the conventional kit protocol),the RBY-stained group with a final concentration of 0.08 g/L,the RBY-stained group with a final concentration of 0.16 g/L,the ERY-stained group with a final concentration of 0.08 g/L,and the ERY-stained group with a final concentration of 0.8 g/L.Gels were prepared and subjected to electro-phoresis,followed by coomassie brilliant blue staining to visualize protein bands.Subsequently,proteins were transferred to PVDF membranes,which were then blocked,incubated with primary and secondary antibodies,washed,and finally ex-posed for imaging to observe the target protein vinculin bands.RESULTS:Compared with the unstained concentrate gel,the loading wells of the RBY or ERY pre-stained concentrate gel were more clearly visible.Analysis of the gels stained with coomassie brilliant blue after electrophoresis and marker visualization showed no significant different in protein elec-trophoretic mobility between prestained and unstained gels.Comparative analysis of the immunoblotting also indicated that the detection of protein samples transferred to PVDF membranes was unaffected.CONCLUSION:Prestaining concen-trate gels with RBY or ERY can enhance the efficiency of gel-based electrophoresis and immunoblotting analysis.

Objective To investigate the prevalence and influencing factors of polypoid lesion of gallbladder(PLG)of soldiers stationed on an island.Methods A total of 687 soldiers stationed on an island who underwent annual physical examination from October to December 2020 were selected.They took transabdominal ultrasound and blood biochemical examination,and filled out the questionnaire.There were 62 cases with PLG(PLG group)and 625 cases without PLG(non-PLG group).Age,body mass index(BMI),blood pressure,smoking,eating habits,blood biochemical indexes,and self-rating depression scale(SDS)scores were compared between the two groups.Logistic regression analysis was performed to obtain the independent risk factors for the prevalence of PLG of the soldiers.Results There were significant differences in age,BMI,blood pressure,smoking,irregular diet,total cholesterol(TC),triacylglycerol(TG),low-density lipoprotein cholesterol(LDL-C)and SDS scores between the two groups(all P<0.05).Multivariate Logistic regression analysis showed that age,high BMI,smoking,irregular diet,high TC,high TG,high LDL-C,and high SDS scores were independent risk factors for PLG(all P<0.05).Conclusion There is a high overall prevalence of PLG in the soldiers of this island,which is related to age,high BMI,smoking,irregular diet,high TC,high TG,high LDL-C,and high SDS scores.

Objective:To establish a method for detecting serum non-ceruloplasmin-bound copper (NCC) by immunoprecipitation-inductively coupled plasma mass spectrometry (IP-ICP-MS) and evaluate its clinical application.Methods:Methodological evaluation research. Immunoprecipitation was first used to separate serum ceruloplasmin, followed by detection of serum NCC levels using ICP-MS. Two levels of quality control serum were reconstituted to determine the limit of detection (LOD), limit of quantitation (LOQ), accuracy, and precision of the self-developed method. The serum samples of 131 healthy individuals (healthy group) and 69 first-time diagnosed Wilson′s disease (WD) patients(WD group) from November 2023 to June 2024 in the Affiliated Hospital of Institute of Neurology, Anhui University of Traditional Chinese Medicine were collected. Using self-developed method detected the serum NCC levels, established the healthy reference intervals, and NCC levels between the two groups were compared using the Mann-Whitney U test. Results:The calibration curve exhibited excellent lineary across the concentration range of 1.562 to 300.000 μg/L, as demonstrated by coefficient of determination ( R2) of 0.999. The self-developed NCC method exhibited that the LOD was 0.99 μg/L, the LOQ was 3.29 μg/L, the accuracy (spike and recovery experience) was 87.67%?106.27%, and the intra-batch and inter-batch imprecision expressed as coefficient of variation ( CV) was 2.8%?7.3%, and the healthy reference range was 34.31-71.79 μg/L. The serum NCC levels in the WD group were 102.39 (74.38, 144.04) μg/L, which was significantly higher than those in healthy group (51.45±10.34) μg/L ( Z=?7.967, P<0.01). Conclusions:The established IP-ICP-MS method for detecting serum NCC meets the required analytical performance criteria. It is simply operative, highly sensitive, and provides accurate and reliable results, which could be used for clinical detection.
