Non-steroidal anti-inflammatory drugs(NSAIDs),commonly utilized analgesics,are extensively employed for managing pain associated with musculoskeletal disorders or injuries.Recent clinical studies have demonstrated a heightened risk of bone stress injuries(BSI)in soldiers and athletes,particularly during high-intensity training,due to NSAID usage.Furthermore,the impact of NSAIDs on fracture healing is well-documented;however,the precise mechanism by which their use during training contributes to an increased incidence of stress bone injuries remains unclear.This article aims to summarize potential mechanisms through an extensive review of domestic and international literature in order to standardize the utilization and clinical management of NSAIDs,optimize pain management strategies,and prevent stress bone injuries or fractures in specific populations such as soldiers and elite athletes.

Objective:To study the predictive value of serum fatty acid binding protein 4 (FABP4), serum 25 hydroxyvitamin D [25 (OH) D] and serum visfatin in judging the occurrence of osteoporosis (OP) in elderly pregnant women with diabetes mellitus (GDM) .Methods:120 elderly pregnant women with GDM admitted in Qingdao Municipal Hospital East Branch from May. 2021 to May. 2024 were selected, 16 cases of OP occurred during pregnancy, which were as the observation group, and 104 cases did not occur, which were as the control group. The serum levels of FABP4, 25 (OH) D and Visfatin between the two groups of patients were compared, a Logistic multiple factor model was used to analyze the related factors of OP in elderly GDM pregnant women, a risk prediction regression model was established, and the judgment value of each factor and model were analyzed.Results:There were 16 cases who developed OP among the 120 elderly pregnant women with GDM, the incidence rate was 13.33%. The Logistic multivariate analysis showed that the serum FABP4 ( β=1.074, 95% CI=1.675-5.111, P< 0.001) and serum Visfatin ( β=1.306, 95% CI=2.156-6.322, P<0.001) were independent risk factors for OP in elderly GDM pregnant women, while serum 25 (OH) D ( β=-0.192, 95% CI=0.715-0.952, P=0.008) was independent protective factor for OP in elderly GDM pregnant women. A regression model Logit (P) =1.425+1.074× (X3) -0.192× (X4) +1.306× (X5) was established, which based on the results of logistic multivariate analysis. The ROC analysis results showed that the regression model had a higher accuracy in determining the occurrence of OP in elderly GDM pregnant women ( AUC=0.821, P<0.001) .

The regression model established, which based on the detection of these three factors has high accuracy in determining OP.

Objective:To explore a new surgical approach [anteromedial approach of the hip (AMA)] for Pipkin Ⅰ and Ⅱ femoral head fractures through an imaging and anatomical study.Methods:The hip imaging data were collected of the 38 patients who had undergone lower limb CT angiography for open tibiofibular fractures at Department of Orthopaedics, The Sixth People’s Hospital, School of Medicine, Shanghai Jiao Tong University from June 2023 to January 2024. There were 20 males aged (40.9±3.5) years and 18 females aged (41.5±3.3) years. The origins and shapes of the femoral artery and its main branches were observed. The distances between the femoral head and the femoral artery, the medial femoral circumflex artery, and the lateral femoral circumflex artery were measured. Four fresh adult cadavers were collected, including 2 males and 2 females. Their ages of death were 56, 65, 72 and 78 years old, respectively. An incision was made along the axis of the limb at the midpoint of the inguinal ligament at the 4 fresh cadavers. After the femoral head was exposed through the gap between the femoral artery and the femoral nerve, the range of the femoral head exposed was marked.Results:The femoral artery ran along the anteromedial side of the femoral head. The shortest distance between the medial femoral circumflex artery and the femoral head was (13.1±5.7) mm, and the shortest distance between the origin of the lateral femoral circumflex artery and the femoral head (21.6±8.6) mm. On the lateral view of CT angiography, the distance between the femoral artery and the femoral head was (20.6±4.9) mm at the level of the apex of greater trochanter. Gross observation on the cadavers found only small branches of vessels between the femoral artery and the femoral nerve. After the femoral artery and femoral nerve were respectively pulled medially and laterally, the anterior-inferior part of the femoral head was exposed directly by pulling the muscles to open the joint capsule. The exposure range of the femoral head was further expanded through internal and external rotation of the hip joint under traction. The anatomical gap between the femoral artery and the femoral nerve was named the AMA.Conclusion:AMA utilizes the potential gap between the femoral artery and the femoral nerve, providing a new surgical approach for exposure and fixation of Pipkin type Ⅰ and Ⅱ femoral head fractures.

Objective:The relationship between benign prostatic hyperplasia(BPH)and the oxidative balance score(OBS)will be discussed in this study.Methods:The clinical data on 16 dimensions of diet and 4 dimensions of lifestyle from the National Health and Nutrition Examination Survey(NHANES)from 2001 to 2008 were used to calculate OBS.We considered BPH as the out-come and investigated the linear and nonlinear relationships between the two.Additionally,subgroup analyses and interaction tests were conducted as well.Furthermore,the methods of machine learning including XGBoost,support vector machine(SVM)and naive Bayes(NB)were used to establish a predictive model for BPH.Results:Higher OBS was consistently associated with an increased preva-lence of BPH,with Restricted Cubic Splines highlighting a significant positive nonlinear association(P=0.015).Subgroup analyses revealed differences and interactive relationships based on alcohol consumption.Among the seven machine learning models that we in-cluded the OBS score in,the XGBoost model emerged as the best,with an AUC value of 0.769.Conclusion:There is a significant association between OBS and the prevalence of BPH in the American population,which provides a valuable insight for further diagnosis and research of the disease.

Objective： To investigate the relationship between the lipid metabolism-related gene sterol carrier protein 2(SCP2) and prostate cancer (PCa) from a multi-omics perspective using single-cell transcriptomes combined with Mendelian randomization. Methods： Single-cell transcriptome data of benign and malignant prostate tissues were obtained from GSE120716, GSE157703 and GSE141445 datasets, respectively. Integration, quality control and annotation were performed on the data to categorize the epithelial cells into high and low SCP2 expression groups, followed by further differential and trajectory analyses. Single nucleotide polymorphism (SNP) data for SCP2 expression quantitative trait loci (eQTL) were subsequently downloaded from Genotype-Tissue Expression (GTEx) and investigated from the PCa Society Cancer-Related Genomic Alteration Panel for the Investigation of Cancer-Related Alterations (PRACTICAL) to obtain PCa outcome data for Mendelian randomization analysis to validate the causal relationship between SCP2 and PCa. Results： High SCP2-expressing epithelial cells had higher energy metabolism and proliferation capacity with low immunotherapy response and metastatic tendency. Trajectory analysis showed that epithelial cells with high SCP2 expression may have a higher degree of malignancy, and SCP2 may be a key marker gene for differentiation of malignant epithelial cells in the prostate. Further Mendelian randomization results showed a significant causal relationship between SCP2 and PCa development (OR=1.045, 95% CI: 1.010 －1.083, P=0.011). Conclusion： By combining single-cell transcriptome and Mendelian randomization, the role of the lipid metabolism-related gene SCP2 in PCa development has been confirmed, and new targets and therapeutic directions for PCa treatment have been provided.

Objective To explore the changes of durability properties of reusable surgical gowns when used in dry and wet conditions.Methods Reusable surgical gowns made of single-layer polyester fiber or 3-layer composite material were selected as test samples,and a Martindale abrasion and pilling tester was used as the basic test platform and modified to form fixtures suitable for the wet state environment.The reusable surgical gowns underwent abrasion experiments in wet and dry conditions to observe the changes in their fiber structure,and were subjected to water penetration resistance and swelling strength tests.Results Visually the reusable surgical gowns had few changes of the microscopic textile fiber structure in dry and wet conditions,and the gowns made of single-layer polyster fiber gained advantages over the outer layers of those of 3-layer composite material in abrasion resistance with the same friction cycles.In dry and wet conditions,the hydrostatic pressure values of the gowns of single-layer polyster fiber gradually decreased with the increase of the degree of abrasion,which were always lower than those of the gowns of 3-layer composite material;the swelling strength of the gowns of single-layer polyster fiber was always greater than that of the gowns of 3-layer composite material,which decreased with the deterioration of the wear more significantly than that of the gowns of 3-layer composite material.Conclusion The reusable surgical gowns made of single-layer polyester fiber or 3-layer composite material have few differences in durability and protective properties at the early stages of ablation in dry and wet conditions.The durability of the gowns decreases as the degree of wear increases,while the trend of the decrease is slowing down until the fabric breaks down and completely loses its barrier effect.[Chinese Medical Equipment Journal,2025,46(6):28-33]

Based on the pharmacokinetics theory, this study investigated the pharmacokinetic characteristics of albiflorin, paeoniflorin, wogonoside, and wogonin in normal and febrile rats and summarized absorption and elimination rules of Dayuanyin in them to provide reference for further development and clinical application of Dayuanyin. Blood samples were taken from the fundus venous plexus of normal and model rats after intragastric administration of Dayuanyin at different time points. The concentration of each substance in blood was determined by ultra performance liquid chromatography-triple quadrupole mass spectrometry(UPLC-MS/MS) technique at different time points. DAS 2.0, a piece of pharmacokinetics software, was used to calculate the pharmacokinetic parameters of each component. The results show that the 4 components had good linear relationship in their respective ranges, and the results of methodological investigation met the requirements. The pharmacokinetic parameters of C_(max), T_(max), t_(1/2), AUC_(0-t), AUC_(0-∞), and MRT_(0-t) were calculated by the DAS 2.0 non-compartmental model. Compared with those in the normal group, C_(max) and AUC_(0-t) of the 4 components in the model group were significantly increased. There were significant differences in the pharmacokinetic characteristics between the normal and model groups, suggesting that the absorption and elimination of Dayuanyin may be affected by the changes of internal environment of the body in different physiological states.

Lung cancer is one of the most common and deadliest cancers globally, with its incidence and mortality rates rising each year. Therefore, finding new, safe, and effective alternative therapies poses a significant research challenge in this field. Programmed cell death refers to the process by which cells actively self-destruct in response to specific stimuli, regulated by genetic mechanisms. Modern research indicates that dysregulation of programmed cell death is widespread in the occurrence and progression of lung cancer, allowing cancer cells to evade death while continuing to proliferate and metastasize. Thus, inducing the death of lung cancer cells can be considered a novel therapeutic strategy for treating the disease. In recent years, research on traditional Chinese medicine(TCM) in the field of oncology has gained widespread attention, becoming a focal point. An increasing number of studies have demonstrated that TCM can inhibit the progression of lung cancer and exert anti-cancer effects by inducing apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis. This paper provided a comprehensive review of the molecular mechanisms of programmed cell death in lung cancer, along with the potential mechanisms and research advancements related to the regulation of these processes by TCM, so as to establish a theoretical foundation and direction for future basic and clinical research on lung cancer.
