Background Hebei Province is located in the North China Plain. In view of the influence of geological background and the acute and chronic hazards caused by excessive drinking water toxicological indicators, coupled with the large coverage of water supply in urban areas and the existence of self-built water supply facilities, it is necessary to understand the drinking water sanitation status in urban areas and conduct health risk assessment. Objective To investigate main indicators affecting the compliance rate of drinking water quality in urban areas of Hebei and evaluate the chronic non-carcinogenic risks of 11 chemicals. Methods The collection, preservation, and testing of 14299 samples of finished water, tap water, and secondary water supply in urban areas of Hebei Province from 2017 to 2021 were conducted following the Standard examination methods for drinking water (GB/T 5750—2006). A total of 11 chemicals were evaluated according to the Hygienic standards for drinking water (GB 5749—2006). The chronic non-carcinogenic risks of the 11 chemicals in drinking water by oral exposure were assessed using the four-step health risk assessment model developed by the United States Environmental Protection Agency and the Technical guide for environmental health risk assessment of chemical substances (WS/T 777—2021). Results From 2017 to 2021, the compliance rates of arsenic, cadmium, hexavalent chromium, lead, mercury, selenium, cyanide, chloroform, and carbon tetrachloride in drinking water in urban areas of Hebei Province were all 100.00%, and fluoride and nitrate (N) were the main indicators affecting water quality compliance, with compliance rates of 97.68% and 99.53% respectively. The compliance rate of fluoride increased year by year (χ²=178.06, P<0.05), and the concentration showed a downward trend (χ²=563.49, P<0.05). The compliance rate of fluoride in water samples during the wet season was higher than that during the dry season (χ²=5.06, P<0.05). The median concentrations of fluoride and nitrate in drinking water in urban areas of Hebei Province from 2017 to 2021 were 0.36 mg·L⁻¹ and 3.32 mg·L⁻¹, with hazard quotients of 0.15 and 0.05, respectively, both less than 1, suggesting no chronic non-carcinogenic risks, and no significant gender difference was found. The hazard quotient of maximum fluoride concentration was 1.65, which was greater than 1, suggesting chronic non-carcinogenic risks. The chronic non-carcinogenic risks associated with the maximum concentrations of the remaining 10 chemical indicators were all within an acceptable range. Conclusions Nine toxicological indicators in drinking water in urban areas of Hebei Province from 2017 to 2021, except for fluoride and nitrate, are within the national standards. Fluoride and nitrate are the main toxicological indicators that affect the overall compliance rate of water quality, and the chronic non-carcinogenic risks associated with maximum concertration of nitrate and 95% concentration of fluoride are at an acceptable level.

Objective To explore the effect of sling exercise with Tuina therapy on kinesiophobia in old patients with lumbar disc herniation,and analyze the mechanism based on brain-bone axis. Methods A total of 56 old patients with chronic lumbar disc herniation and kinesiophobia were selected from the Reha-bilitation Hospital of the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September,2022 to December,2023;and randomly divided into control group(n=28)and experimental group(n=28).The control group accepted conventional exercise therapy,while the experimental group accepted sling exercise with Tuina therapy,for four weeks.They were assessed with simplified Chinese version of Tampa Scale of Kinesiophobia(TSK),Japanese Orthopaedic Association score(JOA)and Visual Analogue Scale for pain(VAS)before and after treatment,while the bone mineral density(BMD)was tested,the levels of osteoprote-gerin(OPG),norepinephrine(NE)and corticosteroids(Cor)in serum were measured,and the median frequency(MF)of weak-link erector spinae was detected with surface electromyography. Results Two cases dropped off in the control group,and one in the experimental group.The scores of all the assessment improved in both groups after treatment(|t|>14.168,P<0.001),as well as the serum levels of OPG,NE and Cor(|t|>2.103,P<0.05),BMD(|t|>2.726,P<0.05),and MF of erector spinae(|t|>14.736,P<0.001);all of them were better in the experimental group than in the control group(|t|>2.154,P<0.05). Conclusion Sling exercise with Tuina therapy can improve the pain and kinesiophobia of lumbar disc herniation in the old adults,which may promote the recovery of physical and mental function through regulating the levels of hor-mones and neurotransmitters related to the brain-bone axis.

Objective To investigate the MRI features of primary retroperitoneal leiomyosarcoma(PRLS).Methods Thirty-three cases of pathologically confirmed PRLS were analyzed retrospectively,and their multi-parameter MRI features were analyzed qualitatively and quantitatively.Results Of the 33 PRLS,24 cases were located in the renal hilum,inferior vena cava,or the area around the bifurcation of the iliac vessels.Twenty-four cases had relatively intact capsule,25 cases had necrosis,and 15 cases had coagulated geographic necrosis.The mean diameter of the tumors was(9.9±5.1)cm,ranging from 3.0 to 20.7 cm,among which 27 cases with a diameter larger than 5 cm.The tumor parenchyma of the 33 PRLS all showed significantly high signal intensity on diffusion weighted imaging(DWI),and significantly low signal intensity on apparent diffusion coefficient(ADC)map.The tumor parenchyma showed moderate to obvious degree of progressive enhancement,and the signal intensity value of the tumor in each phase after contrast injection was higher than that of the psoas major muscle(P＜0.001).Conclusion PRLS are usually large but have a relatively intact capsule and are closely related to the major retroperitoneal veins.The coagulated geographic necrosis,significantly limited diffusion of water molecules,and progressive enhancement pattern all show certain MRI characteristics.
