Objective To investigate the level of perceived health competence in patients with hepatolenticular degeneration, also known as Wilson disease (WD), as well as related influencing factors. Methods From January to December 2023, the convenience sampling method was used to select 60 patients with WD as the subjects for this study among the patients who were hospitalized in The Affiliated Hospital of the Neurology Institute of Anhui University of Chinese Medicine, and General Information Questionnaire, Perceived Health Competence Scale, Health Literacy Scale, Perceived Social Support Scale, and Perceived Control Scale were used to investigate the influencing factors for perceived health competence in patients with WD. Results The total score of perceived health competence was （25.85±5.03） in the patients with WD, with an outcome expectancy score of （12.12±3.55） and a behavioral expectancy score of （13.73±3.33）, and the multivariate analysis showed that degree of education and health literacy assessment were influencing factors for perceived health competence in the patients with WD. Conclusions There is a moderate level of perceived health competence in patients with WD, which is influenced by the factors such as degree of education and health literacy assessment.

OBJECTIVE: To compare the short-term effectiveness between Gamma 3 intramedullary nails and Gamma 3 U-Blade system in the treatment of osteoporotic intertrochanteric fractures in the elderly. METHODS: A retrospective analysis was conducted on the clinical data of 124 elderly patients with osteoporotic intertrochanteric fractures, who were admitted between February 2020 and February 2023 and met the selection criteria. The fractures were fixed with Gamma 3 intramedullary nails in 65 patients (control group) and Gamma 3 U-Blade systems in 59 patients (UB group). The differences between the two groups were not significant in age, gender, body mass index, American Society of Anesthesiologists (ASA) classification, bone mineral density, time from injury to operation, fracture classification, and affected side ( P>0.05). The operation time, intraoperative blood loss, hospital stay, and fracture healing time were recorded; the tip-apex distance, fracture reduction quality, and lag screw position were evaluated on X-ray films at immediate after operation; the lag screw sliding distance and change value of neck-shaft angle were measured on X-ray films at last follow-up. Harris hip score at 1 year after operation and the occurrence of internal fixation-related complications were compared between the two groups. RESULTS: The operation time, intraoperative blood loss, and hospital stay in the UB group increased compared to the control group, but the differences were not significant ( P>0.05). All patients in both groups were followed up 12-24 months (mean, 17.1 months). At 12 months after operation, there was no significant difference in the Harris hip score between the two groups ( P<0.05). Radiological examination showed that there was no significant difference between the two groups ( P>0.05) in terms of tip-apex distance, fracture reduction quality, and lag screw position. Fractures healed in both groups, and there was no significant difference in healing time ( P>0.05). At last follow-up, the change value of neck-shaft angle and lag screw sliding distance in the UB group were significantly lower than those in the control group ( P<0.05). During follow-up, no related complications occurred in the UB group, while 6 cases (9.2%) in the control group experienced complications, and the difference in the incidence was significant ( P<0.05). CONCLUSION For the osteoporotic intertrochanteric fractures in the elderly, the Gamma 3 U-Blade system fixation can achieve good short-term effectiveness, with better imaging results compared to Gamma 3 intramedullary nails fixation.

Long-term burden of illness and associated medication usage make osteoporosis(OP) a common complication of respiratory diseases. The pathogenic risk factors and treatment strategies for respiratory diseases related OP are similar to primary OP. However, due to differences in the pathogenesis of each disease, there are distinctions in the characteristics of bone loss and treatment approaches. Therefore, targeted diagnostic and therapeutic plans need to be formulated. This article provides a comprehensive review of secondary OP caused by common respiratory diseases in terms of epidemiological characteristics, related risk factors or possible mechanisms, changes in bone metabolic indexes or characteristics of bone damage, and progress in diagnosis and treatment. The aim of this review is to offer insights into the prevention and treatment of secondary OP related to respiratory diseases and promote the development of a multidisciplinary collaborative approach.

Gliomas are the most common primary intracranial tumors in adults, among which high-grade glioma patients are characterized by short survival and poor prognosis. The diagnosis, treatment, evaluation of effective treatments, and prognosis prediction of high-grade gliomas are of great significance for improving patient survival. Conventional enhanced magnetic resonance imaging has deficiencies in delineating tumor extent, identifying tumor progression and treatment-related changes. Therefore, there is a broad consensus to incorporate amino acid PET, and ¹⁸F-FET PET inparticular, into the diagnostic and therapeutic process of high-grade gliomas. In this article, we review the new research progress of ¹⁸F-FET PET in the diagnosis and treatment of adult high-grade glioma in recent years.

Cognitive impairment is a kind of senile disease that leads to the decline of personality and behavior ability of the elderly,which seriously affects the quality of daily life of patients.The prevalence rate of the disease increases year by year with the acceleration of the aging process of the society,and its incidence is affected by many risk factors.At this stage,the curative effect for middle and advanced patients is poor.So early identification and intervention to delay the progression of cognitive impairment have become the focus of relevant research.Blood pressure variability can lead to damage of target organs such as heart,brain tissue and kidney,which is closely related to cognitive impairment.In order to expand a new perspective of early intervention in cognitive impairment,this paper reviews the effects of blood pressure variability on different cognitive impairment and its possible pathogenic mechanism.

Alzheimer disease(AD),commonly known as senile dementia,is the most common type of dementia,resulting in progressive impairment of cognitive function,and is often accompanied by a variety of psychiatric symptoms,such as agitation.Agitated symptoms in AD patients often cause an increasing burden on caregivers,and current psychiatric medications may exacerbate adverse effects such as cognitive impairment and motor retardation in patients.Therefore,non-drug intervention is a very important adjuvant treatment option.This article reviews the clinical manifestations,possible mechanisms,drug therapy and non-drug intervention measures of agitation in order to provide reference for more effective treatment of AD.

Objective To investigate the correlations of serum cyclic adenosine monophosphate-responsive element binding protein regulator of transcription coactivator 3 (CRTC3) and oxidative stress indicators with carotid atherosclerosis in patients with coronary heart disease (CHD). Methods A total of 154 CHD patients in the hospital from June 2021 to June 2023 were selected as study group and divided into mild, moderate, and severe atherosclerosis groups based on the degree of carotid atherosclerosis; another 154 healthy individuals with physical examinations in the same period were selected as control group. Pearson method was used to analyze the correlations of serum CRTC3 and oxidative stress indicators with carotid atherosclerosis indicators. Results Serum CRTC3 and malondialdehyde (MDA), carotid plaque area and intima-media thickness (IMT) in the study group were significantly higher than those in the control group, while the levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were significantly lower than those in the control group (P < 0.05). In the mild, moderate and severe atherosclerosis groups, serum CRTC3 and MDA levels, carotid plaque area, and IMT significantly gradually increased, while SOD and GSH-Px levels significantly gradually decreased (P < 0.05). Pearson correlation analysis showed that serum CRTC3 and MDA levels were positively correlated with carotid plaque area and IMT (P < 0.05), while SOD and GSH-Px were negatively correlated with carotid plaque area and IMT (P < 0.05). The receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) for the combined diagnosis of severe carotid atherosclerosis by CRTC3, SOD, MDA and GSH-Px was 0.990 (95%CI, 0.982 to 0.998), with a sensitivity of 96.27% and a specificity of 76.28%. The diagnostic value of the combined application of these four indicators was significantly higher than that of each indicator alone (Z_{combined-CRTC3}=2.723, Z_combined-SOD=2.698, Z_combined-MDA=2.673, Z_{combined-GSH-Px}=2.803, P < 0.05). Conclusion The serum levels of CRTC3 and MDA are significantly increased while SOD and GSH-Px levels are significantly decreased in CHD patients. Both serum CRTC3 and oxidative stress levels are closely related to carotid atherosclerosis.

Objective:Heme chloride(Hemin)is an in vitro purified form of natural heme and an important raw material for anti-anemia and antitumor drugs.This study aims to analyze the protective effect of Hemin on tissue damage in low-pressure oxygen chamber simulated plateau hypoxic mice,and explore its role in anti-plateau hypoxia. Methods:Thirty male BALB/c mice were randomly divided into a blank group,a positive drug group(acetazolomide,200 mg/kg),a Hemin low-dose group(15 mg/kg),a Hemin medium-dose group(30 mg/kg),and a Hemin high-dose group(60 mg/kg)with intraperitoneal injection.The anti-hypoxic activity of Hemin was explored by atmospheric closed hypoxia experiment and the optimal dose was screened.Thirty-six male BALB/c mice were randomly divided into a blank group,a hypoxia group,a positive drug group,and a Hemin high-dose group.The plasma inflammatory factor levels and oxidative stress indicators malondialdehyde(MDA),glutataione(GSH),and superoxide dismutase(SOD)levels of myocardium,brain,lung,and liver tissues were measured in different groups with hypoxia for 24 h.The degree of histopathological damage of mice was observed with HE staining.The degree of protection of Hemin against tissue hypoxia injury was detected with the hypoxia probe piperidazole. Results:Compared with the blank group,the survival time of mice in the positive drug group,the Hemin medium-dose group,and high-dose group was significantly extended(all P<0.05),with the highest prolongation rate in the Hemin high-dose group.Compared with the hypoxia group,mice in the Hemin high-dose group showed a significant increase in SOD level and GSH content of brain tissue,and a significant decrease in MDA content of lung tissue(all P<0.05).The results of HE staining and hypoxia probe showed that Hemin had a significant protective effect on the damage of liver,heart,brain and lung tissues of mice with hypoxia,and the most obvious effect on that of the brain tissue. Conclusion:Hemin has an effect of improvement on oxidative stress and inflammatory response caused by hypoxia,and has obvious protective effect on tissue damage caused by hypoxia.

Due to factors such as low pressure, low oxygen and cold in the plateau environment, people who enter the plateau rapidly are susceptible to digestive system diseases, such as upper abdominal pain, loss of appetite, nausea and vomiting and other gastrointestinal dysfunction, which seriously affect the health and work ability of people who enter the plateau rapidly. The gastrointestinal dysfunction caused by the rapid advance to the plateau is mainly reflected in three aspects: gastrointestinal motility dysfunction, impaired mucosal barrier function, and intestinal flora imbalance. At present, the pathogenesis of gastrointestinal dysfunction is still not very clear, and there are fewer drugs for targeted prevention and treatment. Gastrointestinal hormones, oxygen free radicals, inflammatory factors, intestinal flora and other factors, as well as the protective effects of related drugs were reviewed in this paper to provide treatment options and theoretical basis for the prevention and treatment of the gastrointestinal emergency response caused by entering the plateau.

Objective:To establish a hyperuricemia rat model through the high temperature-humidity treatment, and monitor its vital signs and biochemical indicator characteristics, as well as observe the changes of renal histomorphology and ultrastructure.Methods:Male SD rats were randomly divided into control(CON) group, potassium oxonate(PO) group and high temperature-humidity(HTH) group, 6 rats each. The experiment lasted for 6 consecutive weeks. Rats from PO group was given 250 mg/kg PO by gavage every day. The rats from HTH group were treated with a special thermostatic incubator for one hour each day after gavaging 250 mg/kg PO. Serum uric acid, creatinine and other indicators were detected every 2 weeks. After 6 weeks, the kidney tissues were collected. The morphological changes and urate crystal deposition of kidney tissues were observed by hematoxylin-eosin staining, Masson′s trichrome staining and gomori staining, while the ultramicrostructural changes of kidney were observed by transmission electron microscope.Results:Two weeks after the experiment, the average serum uric acid values of PO group and HTH group increased significantly, HTH group was higher than PO and CON groups[(133.9±17.8), (107.6±12.4), and (85.7±4.1) μmol/L, P=0.001]. And after 6 weeks, the HTH group was still higher than the other two groups[(115.1±27.8), (82.7±13.9), and (72.9±17.8) μmol/L, P=0.008). The average serum creatinine in HTH group was slightly higher than that in PO group and CON group at 6 weeks[(46.2±4.7), (38.1±6.0), and (28.3±6.3) μmol/L, P=0.001]. Light microscope showed partial renal tubular dilatation in PO group, but renal tubular epithelial cells swelling and inflammatory cells infiltration were more significant in HTH group. The ultrastructural changes such as glomerular podocyte swelling were found in HTH group by transmission electron microscope. Conclusion:In this study, we had successfully established a hyperuricemia rat model by simulating the high temperature-humidity environment combined with potassium oxyzinate after 2 weeks of experiment. After 6 weeks of modeling, it was found that the high temperature-humidity induced rat models possessed a relatively higher and stabler serum uric acid level than that of the traditional chemical medicine induced rats. The method can be applied to the research of pathogenesis and pharmacotherapy of hyperuricemia caused by high temperature-humidity environment.
