BACKGROUND:The pathogenesis of nontraumatic necrosis of the femoral head is still unclear.Among them,the lipid metabolism disorder is an important hypothesis of the cause of nontraumatic necrosis of the femoral head.Regulating blood lipid metabolism to inhibit the progression of femoral head necrosis has become an important method for the treatment of nontraumatic femoral head necrosis.OBJECTIVE:To review the research progress in the relationship between nontraumatic necrosis of the femoral head and lipid metabolism disorder and the treatment of nontraumatic necrosis of the femoral head.METHODS:Using"osteonecrosis of femoral head,nontraumatic osteonecrosis of femoral head,femoral head necrosis,osteonecrosis and lipid,lipid metabolism osteonecrosis,polymorphisms osteonecrosis of femoral head,pathway osteonecrosis of femoral head,steroid-induced osteonecrosis of the femoral head,alcohol-induced osteonecrosis of femoral head"as Chinese and English search terms,relevant articles were searched on CNKI,WanFang databases,Yiigle,and PubMed databases.Finally,104 articles were included for summarization.RESULTS AND CONCLUSION:(1)Patients with femoral head necrosis are often accompanied by dyslipidemia.It was found that high total cholesterol,high triglyceride,high low-density lipoprotein cholesterol,high apolipoprotein B,low low-density lipoprotein cholesterol and low apolipoprotein were the risk factors causing necrosis of the femoral head.In patients with different triggers of femoral head necrosis,blood lipid levels are usually different.(2)Hormone and alcohol,as the two major causes of nontraumatic necrosis of the femoral head,can induce adipogenic differentiation of bone marrow mesenchymal stem cells,increase the number of fat cells in the bone marrow cavity,and accumulate fat droplets,ultimately leading to necrosis of the femoral head.(3)Many adipokines and molecules related to lipid metabolism,such as adiponectin,leptin,lipid carrier protein 2,etc.have been confirmed to be related to femoral head necrosis.(4)Some signaling pathways,such as peroxisome proliferator-activated receptor γ,wnt/β-catenin and adenosine activated protein kinase,can change the osteogenic and adipogenic differentiation potential of bone marrow mesenchymal stem cells,and thus participate in the occurrence and development of necrosis of the femoral head.Lipid metabolism signaling pathways,such as phosphatidylinositol 3 kinase/protein kinase Band bone morphogenetic protein 2,are also related to necrosis of the femoral head,which may affect the progression of femoral head necrosis through the regulation of lipid metabolism.(5)Studies have found that cordycepin,Panax notoginseng saponins,gushiling capsule and other Chinese medicines,as well as statins can achieve the therapeutic effect on nontraumatic necrosis of the femoral head by improving lipid metabolism disorder.

To summarize the perioperative nursing experience of a patient with thoracic and abdominal aortic dissection aneurysm after Stanford type A aortic dissection surgery,who underwent intra-abdominal aortic aneurysm endovascular isolation,in situ fenestration branch covered stent placement,and artificial blood vessel bypass.The nursing points include regular evaluation of the intra-abdominal pressure of the patient,being on guard against the rupture of the dissection;specialist nurses participated in the preoperative multidisciplinary discussion;establishing an emergency plan for the rescue of ruptured aortic dissection;monitoring the vital signs of patients closely to prevent critical complications during surgery.After multidisciplinary treatment and meticulous care,the patient's surgery went smoothly and the postoperative recovery was good.The patient was discharged 8 days later.

This article reports a rare case of a 24-year-old male with congenital insensitivity to pain with anhidrosis (CIPA) complicated by joint injuries. The patient has presented with an absence of pain sensation, anhidrosis, and recurrent lower extremity fractures since childhood, and has gradually developed severe bone and joint injuries in the lower extremities in adulthood. Combined with the medical history, physical examination, and imaging features, whole exome sequencing identified compound heterozygous pathogenic mutations in the NTRK1 gene: c.851-33T>A (maternal) and c.963del (paternal), consistent with an autosomal recessive inheritance pattern. Literature analysis indicates that NTRK1 mutations lead to abnormal nerve growth factor signaling, causing loss of pain sensation, autonomic nerve dysfunction, and recurrent self-harm behaviors, which in turn induce skeletal system complications such as fractures, hip dislocation, osteomyelitis, and infections. The imaging features are mainly characterized by bone resorption, joint deformities, and Charcot joints. The patient's synovial chondroma of the right knee joint is a rare CIPA. Currently, there is no cure for CIPA, and treatment focuses on injury prevention, anti-infection, and supportive care. Stem cell therapy and gene editing technology may be potential directions. Due to the lack of a pain protection mechanism, CIPA patients are prone to psychological problems and require multidisciplinary collaborative intervention.

Objective:To investigate the iodine nutritional status of pregnant women in Jilin Province and its correlation with the distribution characteristics of water iodine in external environment, providing a basis for scientific iodine supplementation and prevention of iodine deficiency disorders.Methods:A retrospective analysis was conducted on the iodine survey data of drinking water for residents in Jilin Province in 2017 and the monitoring data of iodine deficiency disorders in 2021. The water iodine, salt iodine, and urinary iodine level of pregnant women were analyzed.Results:In 8 866 water samples from 873 townships (streets, hereinafter referred to as townships) of 60 counties (cities, districts) in 9 cities (autonomous prefectures) throughout the province, the median of water iodine was 4.60 μg/L, ranging from 0.00 to 81.30 μg/L. Among them, there were 758 townships with a median water iodine < 10 μg/L, accounting for 86.83% (758/873); 107 townships with a water iodine of 10 - < 40 μg/L, accounting for 12.26% (107/873). The median salt iodine was 23.50 mg/kg in 6 000 household consumption salt samples. The iodized salt coverage rate, iodized salt qualified rate, and qualified iodized salt consumption rate were 99.50% (5 970/6 000), 97.30% (5 809/5 970), and 96.82% (5 809/6 000), respectively. The iodized salt coverage rate in 9 cities (autonomous prefectures) were > 95%, the iodized salt qualified rate and qualified iodized salt consumption rate were > 90%. The median urinary iodine in 6 000 pregnant women's urine samples was 169.05 μg/L. Except for Bayshan City, which was iodine-deficient, the other 8 cities (autonomous prefectures) were iodine-suitable. The results of correlation analysis showed that there was no correlation between the urinary iodine level of pregnant women and the distribution of water iodine in the external environmental at the municipal (autonomous prefecture) level ( r = 0.60, P = 0.089). Conclusions:Most townships in Jilin Province are iodine-deficient in the external environment, and there are no water-borne high iodine area. The iodized salt coverage rate, iodized salt qualified rate, and qualified iodized salt consumption rate all meet the national standards. The iodine nutrition of pregnant women is generally at a suitable level, but there are still some areas where pregnant women are iodine-deficient, and there is no correlation with the distribution of water iodine.

Objective:To learn about the cognition of iodine deficiency disorders (IDD) prevention knowledge among key population in the IDD area of Jilin Province, and to evaluate the effect of health education.Methods:From 2015 to 2019, 10 counties (cities, districts, hereinafter referred to as counties) in Jilin Province were selected as project counties every year. Public health education covered the entire project county. In each project county, 3 project townships were selected, and students of grades 4-6 were selected from the central primary schools of each project township for school health education. In each project township, 3 project villages were selected to carry out community health education. Before and after health education, 30 fifth-grade students were selected from the central primary school of each project township, and 15 housewives were selected from the vicinity of each primary school to conduct a questionnaire survey on IDD prevention knowledge.Results:After health education, the overall awareness rate of IDD prevention knowledge among primary school students and housewives in Jilin Province was 96.26% (13 324/13 842) and 96.40% (6 819/7 074), which was significantly higher than that before the intervention [65.36% (9 032/13 818) and 71.26% (5 039/7 071)], and the differences were statistically significant (χ 2 = 4 258.34, 1 647.92, P < 0.001), and the awareness rates of primary school students and housewives increased by 30.90% and 25.14%, respectively. Conclusion:Health education has significantly increased the awareness rate of IDD prevention knowledge among key populations in Jilin Province, and is an important measure to ensure the continuous elimination of IDD.

Objective:To investigate the clinical efficacy of high-frequency repetitive transcranial magnetic stimulation combined with electrical stimulation in patients with dysphagia after stroke.Methods:Seventy-two stroke patients with dysphagia who received treatment in The First Hospital of Jiaxing from February 2019 to February 2020 were included in this study. They were randomly assigned to receive either electrical stimulation (control group, n = 36) or high-frequency repetitive transcranial magnetic stimulation combined with electrical stimulation (observation group, n = 36) for 2 weeks. Changes in serum brain-derived neurotrophic factor, neuron-specific enolase, and vascular endothelial growth factor levels after treatment relative to before treatment were observed in each group. Scores of the swallowing function assessment scale, neurological deficit, and quality of life were compared between the control and observation groups. Results:After treatment, serum levels of brain-derived neurotrophic factor and vascular endothelial growth factor in the observation group were (7.98 ± 1.14) μg/L, (168.78 ± 10.28) ng/L, respectively, which were significantly higher than those in the control group [(5.80 ± 1.10) μg/L, (110.34 ± 10.47) ng/L, t = 8.26, 23.90, both P < 0.01]. Serum neuron-specific enolase level was significantly lower in the observation group than in the control group [(7.57 ± 1.17) μg/L vs. (10.66 ± 1.30) μg/L, t = 10.60, P < 0.001). The scores of swallowing function assessment scale and neurological deficits in the observation group were (2.47 ± 1.16) points and (7.03 ± 1.14) points, respectively, which were significantly lower than those in the control group [(5.75 ± 1.10) points, (9.66 ± 1.20) points, t = 12.31, 9.53, both P < 0.001]. Total effective rate [97.22% (35/36) vs. 77.78% (28/36)] and the score of swallowing quality of life questionnaire [(160.40 ± 8.32) points vs. (146.74 ± 8.10) points] were significantly higher in the observation group than in the control group ( χ2 = 4.57, P = 0.03, t = 7.25, P < 0.001). Conclusion:High-frequency repetitive transcranial magnetic stimulation combined with electrical stimulation can greatly improve neurological function and swallowing function of stroke patients with dysphagia. The combined therapy is of certain clinical value and innovation.
