BACKGROUND:Acute exercise tends to cause skeletal muscle tissue damage and lipid metabolism disorders in vivo,but the mechanism by which acute exercise combined with electroacupuncture modulates metabolic and autophagic pathways in vivo is unclear. OBJECTIVE:To observe the changes in metabolic enzymes and autophagy levels in skeletal muscle of rats subjected to acute exercise by electroacupuncture at the acupoints of"Zusanli"and"Huantiao." METHODS:Fifty male Sprague-Dawley rats were randomly divided into three groups:quiet control group(n=10),model group(n=20),and reverse electroacupuncture group(n=20).The latter two groups were set up with two time points,i.e.immediate and 3 hours after exercise groups(n=10 per time point).The model group and the reverse electroacupuncture group underwent acute exercise training after adaptive treadmill training.The rats in the reverse electroacupuncture group underwent electroacupuncture treatment(parameters:electroacupuncture on both sides of the rats at the acupoints of"Zusanli"and"Huantiao,"continuous wave,frequency of 2 Hz,intensity of 2 mA,leaving the needle in the body for 30 minutes,once a day for 7 consecutive days)before treadmill training.Bilateral gastrocnemius muscle tissues were taken under anesthesia immediately after exercise and 3 hours after exercise,and hematoxylin-eosin staining was used to observe the histopathological changes of rat skeletal muscle.ELISA kit was used to detect the activities of hepatic lipase,fatty acid synthase,hormone-sensitive lipase,and carnitine palmitoyltransferase 1 in rat skeletal muscle tissues.Immunohistochemistry and western blot were used to detect the changes in the expression of autophagy genes. RESULTS AND CONCLUSION:After hematoxylin-eosin staining,the arrangement of gastrocnemius muscle fibers in the model group was disturbed,swollen and ruptured immediately after exercise and 3 hours after exercise.In the reverse electroacupuncture group,gastrocnemius muscle fibers were tightly arranged and the number of swollen and ruptured cells was greatly reduced immediately after exercise and 3 hours after exercise,and there was no significant difference when compared with the quiet control group.Compared with the quiet control group,the activities of hepatic lipase and fatty acid synthase were lower while the activities of lipoprotein lipase,hormone-sensitive lipase,and carnitine palmitoyltransferase 1 were higher in the model group and the reverse electroacupuncture group 3 hours after exercise(P<0.05 or P<0.01).Compared with the model group,the activities of lipoprotein lipase and carnitine palmitoyltransferase 1 were higher in the reverse electroacupuncture group immediately after exercise(P<0.05),while the activity of lipoprotein lipase was higher and the activity of hormone-sensitive lipase was lower in the reverse electroacupuncture group 3 hours after exercise(P<0.01).Immunohistochemical results showed that compared with the quiet control group,the expression of P62,autophagy-related gene 5 and autophagy-related gene 7 was higher in the model group immediately and 3 hours after exercise,as well as in the reverse electroacupuncture group immediately after exercise(P<0.05 or P<0.01);compared with the model group,the expression of P62 and autophagy-related gene 7 was lower in the reverse electroacupuncture group immediately and 3 hours after exercise(P<0.05).Western blot results showed that the protein expression of P62 and autophagy-related gene 7 in the reverse electroacupuncture group was lower than that in the model group immediately after exercise(P<0.05);the protein expression of Parkin in the model group was higher than that in the quiet control group immediately and 3 hours after exercise(P<0.05);and the protein expression of Parkin in the reverse electroacupuncture group was lower than that in the model group immediately and 3 hours after exercise(P<0.05).To conclude,acute exercise induces disorders,swelling and rupture of gastrocnemius muscle fibers in rats and electroacupuncture on both sides of the acupoints of"Zusanli"and"Huantiao"can improve the level of lipid metabolism and regulate autophagy cells in rat skeletal muscle,preventing the disorders of lipid metabolism and damage of gastrocnemius muscle tissues caused by acute exercise.The mechanism may be closely related to the regulation of autophagy-related factor P62,autophagy-related gene 5,autophagy-related gene 7,and Parkin protein expression to promote the occurrence of autophagy or regulate the autophagy pathway in rat skeletal muscle cells.

GBA1 gene mutation is an important genetic risk factor for Parkinson’s disease (PD). This paper reports a case of a 43-year-old male PD patient carrying a rare heterozygous Thr408Met mutation in the GBA1 gene identified through whole-exome sequencing, leading to a diagnosis of GBA1-associated PD. The patient’s motor symptoms were primarily characterized by bradykinesia and rigidity, without significant cognitive decline. Treatment with low-dose levodopa combined with a dopamine agonist resulted in significant symptomatic improvement.

Fusion variations of neurotrophic receptor tyrosine kinase (NTRK) are oncogenic drivers in various solid tumors such as breast cancer, salivary gland carcinoma, infant fibrosarcoma, etc. Gene rearrangements involving NTRK1/2/3 lead to constitutive activation of the tropomyosin receptor kinase (TRK) domain, and the expressed fusion proteins drive tumor growth and survival. NTRK fusions are estimated to occur at a frequency of approximately 0.1% to 1% in non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) mutations are prevalent in NSCLC, but the frequency of EGFR G719A mutation is relatively low (about 2%), and EGFR mutations are typically mutually exclusive with NTRK fusion variants. The study presented the first documented case of lung adenocarcinoma harboring both EGFR G719A mutation and LMNA-NTRK1 fusion. A review of the literature was conducted to elucidate the role of NTRK fusion mutations in NSCLC and their relationship with EGFR mutations, aiming to enhance the understanding of NTRK fusion mutations in NSCLC.

OBJECTIVES:
To establish a prognostic model for primary liver cancer (PLC) using bioinformatics methods.
METHODS:
Based on the data from 404 patients in the Cancer Genome Atlas (TCGA) database, we constructed a prognostic model integrating the differentially expressed genes, anoikis, and immune-related genes (DAIs) using univariate Cox regression and the LASSO-Cox approach. The predictive ability of the model was evaluated using Kaplan-Meier method and receiver-operating characteristic curves, and a nomogram was developed to facilitate its clinical applications. Gene set enrichment analysis (GSEA) was performed to explore the associated pathways and relationship between the DAIs and the tumor immune microenvironment, and the half-maximal inhibitory concentration (IC50) of liver cancer drugs was calculated using the "pRRophetic" R package. We also detected the expression of SEMA7A in paired tumor and adjacent tissues from liver cancer patients.
RESULTS:
We constructed and validated a prognostic model based on 7 DAIs (NR4A3, SEMA7A, IL11, AR, BIRC5, EGF, and SPP1), and obtained consistent results in both the TCGA training cohort and GEO validation cohort (GSE14520), where the patients in the low-risk group were characterized by more favorable clinical outcomes and immune status. By integrating this prognostic signature with clinical information, a composite nomogram was generated. Somatic mutation analysis showed that TTN, TP53, and CTNNB1 mutations accounted for the largest proportion of total mutations, and the patients in the low-risk-low-TMB group had higher survival rate. Drug sensitivity analysis revealed differences in sensitivity to chemotherapeutic agents between high- and low-risk groups and between TP53 mutations and non-mutations. In clinical tissue specimens, SEMA7A expression was significantly higher in liver cancer tissues than in the adjacent tissues.
CONCLUSIONS
We established a new prognostic model based on DAIs for predicting clinical outcomes and therapeutic response of patients with primary liver cancer.

Journal of Practical Radiology 2024;40(9):1453-1458
Objective To investigate the predictive value of energy spectral CT radiomics on the prognosis of patients with color-ectal adenocarcinoma.Methods The clinical data and preoperative CT enhancement images of 140 patients with pathology confirmed colorectal adenocarcinoma were analyzed retrospectively.The patients were divided into a good prognosis group(n=60)and a poor prognosis group(n=80)based on the whether they had no tumor recurrence or metastasis and died from tumors within 2 years after operation.The region of interest(ROI)was drawn on the 70 keV enhancement images in CT venous phase,and all radiomics features were further extracted.All patients were randomly divided into a training set and a test set at a ratio of 6∶4,and the least absolute shrinkage and selection operator(LASSO)method was used to screen the radiomics features.The prognosis prediction models of colorectal adenocarcinoma patients were constructed by support vector machine(SVM)and extreme gradient boosting(XGBoost),respectively.The area under the curve(AUC)of receiver operating characteristic(ROC)curve was performed to analyze the predictive effective-ness of various models comprehensively.The AUC of models were verified by DeLong test.Results The differences in the energy spectral parameters including water concentration(WC),iodine concentration(IC),and Effective-Z(Eff-Z)in the venous phase were statistically significant between the two groups(P<0.05).The AUC of the SVM model constructed from the radiomics features and the combination features were 0.82 and 0.93,with the accuracy of 0.77 and 0.88.Meanwhile,the AUC of the XGBoost model constructed from the radiomics features and the combination features were 0.90 and 0.98,with the accuracy of 0.86 and 0.93.The AUC,accuracy,sensitivity and specificity of the XGBoost model constructed from the combination of energy spectral CT parameters and radiomics features reached the optimal level,and the differences in AUC were statistically significant by DeLong test(P<0.05).Conclusion Both the SVM and XGBoost models show higher value in preoperative prediction of prognosis of colorectal adenocarcinoma patients,and the combination model of radiomics features and energy spectral parameters(venous phase)has superior predictive effectiveness.

To investigate the differences in postoperative short-term complications and long-term prognosis of pancreatic cancer(PC) patients after total pancreatectomy(TP) and pancreaticoduodenectomy(PD). Clinical data of PC patients who underwent TP from January 2016 to December 2021(TP group) and PD from January 2019 to December 2021(PD group) at Peking Union Medical College Hospital were retrospectively collected. Patients in the PD group were divided into the pancreatic fistula(PF) high-risk PD group and the recurrence high-risk PD group according to risk factors. After propensity score matching, the differences in postoperative short-term surgical efficacy indicators(postoperative complication rate, 30 d mortality rate, length of hospital stay, etc.), long-term surgical efficacy indicators(overall survival), and quality of life were compared between the TP group and the PF high-risk PD group or the recurrence high-risk PD group. A total of 32 patients in the TP group and 114 patients in the PD group(99 patients in the PF high-risk PD group and 15 patients in the recurrence high-risk PD group) meeting the inclusion and exclusion criteria were enrolled.(1)TP group and PF high-risk PD group: after propensity score matching, 29 patients in the TP group and 56 patients in the PF high-risk PD group were finally included. There was no PF in the TP group, and the rate of PF in the PF high-risk PD group was 19.64%( For PC patients at high risk of PF, TP can achieve short-term surgical outcomes and long-term quality of life comparable to PD with no burden of postoperative pancreatic fistula. For patients with high-risk recurrence, TP can significantly prolong the survival of PC patients while ensuring surgical safety.
