Spastic lower limb paralysis is a common complication following central nervous system injury, including stroke, cerebral palsy, and brain or spinal cord trauma, with high incidence and complex conditions. In recent years, minimally invasive treatment techniques have rapidly advanced, offering new avenues to improve motor function and quality of life for these patients. However, clinical decision-making involves multidisciplinary input, such as rehabilitation, neurosurgery, orthopedics, and standardized treatment guidelines are lacking. This review systematically summarizes commonly used minimally invasive treatments for spastic lower limb paralysis, including their mechanisms, indications, efficacy, and limitations, and compares findings from domestic and international studies. The aim is to provide guidance for clinical decision-making, optimize treatment strategies, and promote development of individualized therapies.

Objective To investigate the protective effect and underlying mechanisms of HydroMg, a novel sustained-release hydrogen donor, in a model of doxorubicin (DOX)-induced chronic cardiotoxicity. Methods H9C2 cells were treated with 1 μmol/L DOX and/or 1 μg/mL HydroMg, and mitochondrial membrane potential, reactive oxygen species (ROS) levels, and apoptosis were measured. In the animal experiment, mice were divided into control, HydroMg, DOX, and DOX＋HydroMg groups. The HydroMg group received intraperitoneal injection of HydroMg (100 mg/kg). Chronic cardiotoxicity was established by intraperitoneal injection of DOX (5 mg/kg every week) for four consecutive weeks; In the DOX＋HydroMg group, HydroMg (100 mg/kg) was administered intraperitoneally 4–5 h prior to each DOX injection. Cardiac function and remodeling were evaluated by echocardiography and heart weight index (HWI). The long-term survival of mice were analyzed. Subsequently, transcriptome sequencing was performed on myocardial tissues from the DOX group to identify key molecular alterations compared with controls. Results At the cellular level, HydroMg treatment effectively reversed DOX-induced mitochondrial dysfunction and oxidative stress, as evidenced by restored membrane potential, reductions in total ROS and mitochondrial superoxide levels by approximately 30% and 9%, respectively, and a decrease in the apoptosis rate from 34.13% to 18.27%. In the animal model, compared with the DOX group, HydroMg intervention increased left ventricular ejection fraction (LVEF) and fractional shortening (LVFS) by 9.62% and 5.82%, respectively, attenuated the reduction in HWI (4.41 mg/mm vs 3.53 mg/mm), and improved the 4-week survival rate (80% vs 60%). Transcriptomic analysis revealed that the core molecular features of DOX-induced cardiotoxicity, including widespread suppression of oxidative phosphorylation and antioxidant pathways. Conclusions HydroMg protects against DOX-induced chronic cardiotoxicity by alleviating oxidative stress and improving mitochondrial function, and provides a potential therapeutic strategy against DOX-related cardiotoxicity.

Objective: To analyze the health literacy possession rate and its trend among residents in Lishui City, Zhejiang Province from 2016 to 2024, so as to provide the evidence for improving health promotion strategies and intervention measures. Methods: Multi-stage stratified random sampling combined with probability proportionate to size sampling method was adopted to select permanent residents aged 15-69 years in Lishui City as survey subjects. Demographic information and health literacy possession status were collected through questionnaire survey. The health literacy possession rate was calculated. The data from 2016 to 2019 and from 2020 to 2024 were standardized using the population data of Lishui City from the Sixth National Population Census in 2010 and the Seventh National Population Census in 2020, respectively. The trend of health literacy possession rate from 2016 to 2024 was analyzed. Results: A total of 42 691 people were surveyed, including 20 509 males (48.04%) and 22 182 females (51.96%), with an average age of (51.63±12.13) years. From 2016 to 2024, the health literacy possession rates were 20.40%, 25.83%, 26.96%, 28.82%, 32.30%, 34.02%, 37.53%, 39.21% and 43.17%, respectively, showing an upward trend (P<0.05). Among the three aspects, the possession rates of basic knowledge and concepts, healthy lifestyle and behaviors, and basic skills all showed upward trends (all P<0.05), with basic knowledge and concepts showing the largest increase and basic skills showing the smallest increase. Among the six health issues, the possession rates of scientific health view, chronic disease prevention and control, safety and first aid, basic medical care, and health information showed upward trends, while the infectious disease prevention and control literacy possession rate showed a downward trend (all P<0.05). The possession rates in the 65-69 age group, illiterate/semi-literate residents, and farmers showed upward trends (all P<0.05), but with small increases and remaining at low levels. Conclusions From 2016 to 2024, the health literacy possession rate of residents in Lishui City showed an overall upward trend, but the increase in basic skills literacy possession rate was relatively slow, and the infectious disease prevention and control literacy possession rate showed a downward trend. It is necessary to strengthen health education for weak links and knowledge among elderly people, residents with low educational level, and farmers to improve health literacy level.

Objective:To understand spatial aggregation of lung cancer mortality and its changing trends over the past fifty years in different counties and districts of Shandong Province from 1970 to 2021.Methods:The mortality data of lung cancer were obtained from the death registration system of Shandong province and three retrospective surveys of death cause. The mortality rate and age-standardized mortality rate were used to describe the changing trend of lung cancer in different years, and the contribution value of population factors and non-population factors in lung cancer mortality change was calculated by the mortality differential decomposition method. GeoDa 1.20 and ArcGIS 10.8 software were used for spatial autocorrelation analysis and visualization map display.Results:The crude mortality rate of lung cancer in Shandong Province showed a significant upward trend from 1970 to 2021, rising from 7.22 per 100 000 in 1970-1974 to 62.73 per 100 000 in 2020-2021, with an increase of 7.69 times. Meanwhile, the standardized mortality rate of lung cancer exhibited a trend of increasing first and then decreasing. The differential analysis of lung cancer mortality in different years revealed that changes in crude mortality rates were the result of the combined effects of demographic and non-demographic factors. The proportion of population factors (aging population) leading to an increase in lung cancer mortality rate rose from 2.12% in 1990-1992 to 40.20% in 2020-2021. From a spatial distribution perspective, there were significant regional differences in lung cancer mortality rates among counties (cities, districts) in Shandong Province across different eras. Compared to the period of 1970-1974, the lung cancer mortality rates in all counties and districts in 2020-2021 showed a considerable increase, and there were noticeable changes in the areas of high-high and low-low clustering of lung cancer mortality rates across different eras.Conclusion:There have been significant temporal and spatial changes in the mortality rate of lung cancer in Shandong Province from 1970 to 2021. The crude mortality rate has shown an upward trend, while the standardized mortality rate increases first and then decreases. The concentration of lung cancer mortality rates in counties and districts has also undergone significant changes.

Objective:To explore the predictive value of triglyceride-glucose (TyG) index combined with low-density lipoprotein cholesterol (LDL-C) for major adverse cardiovascular events (MACE) in patients with coronary heart disease (CHD) complicated by type 2 diabetes mellitus (T2DM).Methods:A total of 248 patients with CHD and T2DM admitted to the First Affiliated Hospital of Xinjiang Medical University from July 2022 to January 2024 were retrospectively enrolled. All patients were followed up for 2 years and divided into MACE group (43 cases) and non-MACE group (205 cases) according to the occurrence of MACE. Indicators such as TyG index and LDL-C were compared between the two groups, and their correlations with MACE were analyzed. Multivariate logistic regression was used to screen the risk factors for MACE in patients with CHD and T2DM. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of TyG index, LDL-C, and their combination for MACE in these patients.Results:Compared with the non-MACE group, the MACE group had significantly higher LDL-C [2.63(2.23, 2.95)mmol/L vs 1.99(1.60, 2.66)mmol/L, P<0.001] and TyG index [9.30(8.80, 9.87) vs 8.60(8.09, 9.15), P<0.001]. Multivariate logistic regression showed that TyG index was an independent risk factor for MACE in patients with CHD and T2DM ( OR=10.49, P<0.001). ROC curve results indicated that the area under the curve (AUC) of TyG index and LDL-C for predicting MACE were 0.731 and 0.686, respectively. The combined AUC of the two indicators for predicting MACE was 0.769(95% CI: 0.698-0.840), showing better predictive performance. Conclusions:TyG index combined with LDL-C has high predictive value for the risk of MACE in patients with CHD complicated by T2DM.

Objective:To explore the spatial clustering of the mortality rate of cervical cancer in different counties (cities, districts) in Shandong Province from 1970 to 2021 and its 50-year changing trend, so as to provide basis for the implementation and evaluation of prevention and control strategies and programs such as cervical cancer screening, early diagnosis and treatment, human papilloma virus (HPV) vaccination, etc.Methods:The mortality data of cervical cancer were obtained from the death registration system of Shandong Province and the data of three retrospective surveys of death causes. The mortality rate and age-standardized mortality rate (using the population composition of China in 1964) are used to describe the changing trend of cervical cancer in different years. The contribution values of population factors and non-population factors in cervical cancer mortality change are calculated by mortality differential decomposition method. ArcGIS 10.8 software is used for spatial distribution and spatial autocorrelation analysis.Results:From 1970 to 2021, the crude mortality rate and age standardized mortality rate of cervical cancer in Shandong Province showed a trend of first rapid decline and then slow increase. The crude mortality rate and standardized mortality rate of female cervical cancer in Shandong Province in 1970-1974 were the highest, reaching 17.22/10 5 and 13.17/10 5, respectively. In 2004-2005, it dropped to the lowest levels of 1.50/10 5 and 0.83/10 5. Subsequently, it slowly rose to 4.12/10 5 and 1.56/10 5 in 2020-2021. The differential analysis of cervical cancer mortality in different years found that the change of cervical cancer mortality was caused by the combined action of population factors and non-population factors. Among them, demographic factors (aging population) led to the increase of cervical cancer mortality, but non-demographic factors (early diagnosis and treatment, HPV infection level, medical technology level, etc) lead to the decrease of cervical cancer mortality. Compared with 1970-1974, with the passage of time, the absolute values of the contribution values of population factors and non-population factors showed an increasing trend, while the contribution of non-population factors was greater than that of population factors, which led to the decline of cervical cancer mortality. From the perspective of spatial distribution, there were great regional differences in the mortality rate of cervical cancer in different counties of Shandong Province. In 2020-2021, the mortality rate of cervical cancer in all counties decreased to a great extent compared with that in 1970-1974, and the high-high and low-low concentration areas of cervical cancer mortality in different years changed obviously. The high-aggregation areas of the cervical cancer mortality rate in Shandong Province from 2020 to 2021 were mainly distributed in some counties and districts of Linyi City, Zaozhuang City, and Heze City in the southwest. Conclusions:There are significant temporal and spatial changes in the mortality rate of cervical cancer in Shandong Province from 1970 to 2021. According to these trends and their geographical and spatial clustering, prevention and control strategies of cervical cancer in different regions should be further formulated and evaluated.

OBJECTIVE To investigate the improvement effects and its mechanism of Bazheng powder on chronic urinary tract infection （CUTI） induced by Escherichia coli in rats. METHODS The rats were divided into normal control group， model group， levofloxacin group （45 mg/kg） and Bazheng powder group （4.95 g/kg）， with 10 rats in each group. Except for the normal control group， other groups were administered an intravesical injection of Escherichia coli suspension （1×10⁸ cfu/mL） via the urethra to establish CUTI model； at the same time， rats in each group were administered the corresponding medicinal solution or water by gavage once a day for 4 consecutive weeks. After the last medication， blood routine tests （white blood cell count and lymphocyte percentage）， the levels of serum inflammatory factors [interleukin-1β （IL-1β）， IL-6， IL-8， tumor necrosis factor-α （TNF-α）]， and immune indicators [CD4， CD8， secretory immunoglobulin A （SIgA）]， renal function indicators [cystatin C （Cys-C）， α1- microglobulin （α1-MG）， urea and creatinine] were all determined； the pathological changes in renal and bladder tissues in rats were observed. The protein expressions of Toll-like receptor 4 （TLR4）， nuclear factor-κB （NF-κB）， and nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3） in rat bladder tissues were detected. RESULTS Compared with the normal control group， the levels of IL-1β， IL-6， IL-8， TNF-α， CD8， Cys-C， α1-MG， urea and creatinine in serum， as well as the protein expressions of TLR4， NF-κB and NLRP3 in bladder tissues， were significantly elevated in the model group （P＜0.05）. Conversely， the levels of CD4 and SIgA were significantly decreased （P＜0.05）. Pathological changes， such as extensive infiltration of inflammatory cells， were observed in both renal and bladder tissues. Compared with the model group， the above quantitative indicators in the Bazheng powder group were significantly improved （P＜0.05）， with no obvious inflammatory lesions observed in either renal or bladder tissues. CONCLUSIONS Bazheng powder can alleviate inflammatory reaction and improve the immune function of CUTI rats， and its mechanism may be related to the inhibition of TLR4/NF-κB/ NLRP3 signaling pathway.
