Necroptosis, a form of programmed cell death, initiates a series of biological responses and further culminates in necroinflammatory processes, consequently limiting the efficacy of cytokine antagonists in treating inflammatory diseases. To address this issue, DNAzyme R3-Dz specifically targeting receptor-interacting protein kinase 3 (RIP3) mRNA, a necrosome component, has been successfully developed and studied to elucidate the mechanism in cleaving its target mRNA. Then a polyamidoamine (PAMAM) derivative was constructed through the modification of nucleobase analog (termed AP) to achieve the R3-Dz delivery to macrophages. The AP/R3-Dz nanoparticles effectively downregulated the RIP3 expression, leading to subsequent decrease in the levels of reactive oxygen species (ROS) and damage-associated molecular patterns (DAMPs), ultimately inhibiting the necroinflammatory processes mediated by the NOD-like receptor family pyrin domain-containing 3 (NLRP3). Finally, AP/R3-Dz nanoparticles and their combination with the NLRP3 inhibitor MCC950 suppressed the necrotic phenotype and ameliorated the disease progression in diverse models, including gouty arthritis, autoimmune hepatitis and rheumatoid arthritis. In summary, the AP/R3-Dz nanoparticles in combination with MCC950 have been demonstrated to achieve the intervention in necroptosis and inflammation by dual disruption of the intricate feedback loop of necroinflammation and thus have promising potential in the treatment of inflammatory diseases.

Objective:To explore the effect of exercise on glycemic control and physical indicators among community-dwelling persons with type 2 diabetes mellitus (T2DM).Methods:A total of 42 T2DM patients undergoing regular follow-up at a community health center were divided into a control group and an exercise group. To minimize confounding factors, 1∶1 propensity score matching was performed, resulting in 21 patients in each group. Both groups received standardized diabetes management, including medication, dietary guidance and diabetes health education. The exercise group additionally performed exercises which integrated sports and medical care models. The experiment lasted 8 weeks. Before and after the intervention, glycosylated hemoglobin A1c (HbA1c) levels, body weight, body mass index (BMI), fat mass, visceral fat area (VFA), fat mass index (FMI) and appendicular skeletal muscle mass index (ASMI) were recorded and compared between the two groups. Moreover, the actual exercise compliance of the exercise group was observed, along with any adverse events such as hypoglycemia or exercise-related injuries, as well as changes in antidiabetic medication dosage.Results:After the intervention, significant improvement was observed in both groups in all of the measurements, but with the average HbA1c, BMI, fat mass, VFA and FMI values of the exercise group then significantly better than the control group′s averages. The average compliance rate in the exercise group was 60%. No cases of hypoglycemia or exercise-related injuries were reported during the intervention, and there were no changes in the use of anti-diabetes medications.Conclusions:Exercise effectively improves glycemic control and physical indicators among community-dwelling T2DM patients. However, exercise compliance needs improving.

Insufficient future liver remnant volume remains a critical limitation for single-stage resection in patients with hepatic malignancies. The techniques for promoting future liver remnant hypertrophy to realize two-stage hepatectomy include portal vein embolization, associating liver partition and portal vein ligation for staged hepatectomy, and portal vein ligation. In recent years, the application of auxiliary liver transplantation has further facilitated two-stage total hepatectomy. This article systematically reviews the clinical applications of these techniques and analyzes their advantages and limitations, so as to provide a reference for optimizing clinical decision-making.

Objective To conduct the reductive reservation for torsional ovary in different states(.un-necrotic ovary,suspected necrotic torsional ovary and torsional necrotic ovary)after the ovarian torsion in pre-maturity SD rat,and to investigate its effect on the ovarian reproductive function in maturity stage.Methods A total of 32 SD rats with 3 weeks old were selected and randomly divided into 4 groups,8 cases in each group.The animal model of ovarian torsion was made by using the Turner method,which was similar to the animal model of testicular torsion,and either group was selected to undergo the sham operation as the con-trol group(CG group).The non-necrotic torsional ovary detorsion group(NNTOD group),suspected necrotic torsional ovary detorsion group(SNTOD group)and necrotic torsional ovary detorsion group(NTOD group)were established respectively.When the animals were fed to sexual maturity at 8 weeks of age,the experimen-tal animals were sacrificed by vertebral dislocation method,and the ovary tissues on the torsional side were cut for HE staining and transmission electron microscopy to examine the changes of ovarian histomorphology and mitochondrial structure.Ovarian cell apoptosis was detected by Tunel assay.ELISA method was used to de-tect the follicle-stimulating hormone(FSH),luteinizing hormone(LH)and anti-mullerian duct hormone(AMH)levels in centrifugal blood.Results The ovarian structure in the CG group and NNTOD group was clear,the ovarian follicles at different levels were developed well;the electron microscopy showed normal mi-tochondria.The ovarian partial structure in the SNTOD group was disorganized,the number of follicles at all levels of growth was decreased;electron microscopic examination showed a little damage of mitochondria.In the NTOD group,the arrangement of ovarian structure was obviously disordered,the number of growing folli-cles at all levels was significantly reduced;the electron microscopy showed that most of the mitochondria were obviously swollen and severely damaged.Compared with the CG group,the apoptosis rate in the SNTOD group and NTOD group was significantly increased(P<0.05).There was no statistically significant differ-ence between CG group and NNTOD group(P>0.05).Compared with the NTOD group,the apoptosis rate in the SNTOD group was decreased(P<0.05).Compared with the CG group,the levels of LH and FSH in the SNTOD and NTOD groups were increased,and the AMH level was decreased(P<0.05).The LH and FSH levels in the SNTOD group were lower than those in the NTOD group,the AMH level was higher than that in the NTOD group(P<0.05).Conclusion After reduction of the torsional suspected necrotic ovary in the prematurity rat,the ovarian reproductive function in the torsional side during sexual maturity period is slightly injured;while after reduction of torsional necrotic ovary restoration,its reproductive function is appar-ently damaged.

Objective:To explore the effect of exercise on glycemic control and physical indicators among community-dwelling persons with type 2 diabetes mellitus (T2DM).Methods:A total of 42 T2DM patients undergoing regular follow-up at a community health center were divided into a control group and an exercise group. To minimize confounding factors, 1∶1 propensity score matching was performed, resulting in 21 patients in each group. Both groups received standardized diabetes management, including medication, dietary guidance and diabetes health education. The exercise group additionally performed exercises which integrated sports and medical care models. The experiment lasted 8 weeks. Before and after the intervention, glycosylated hemoglobin A1c (HbA1c) levels, body weight, body mass index (BMI), fat mass, visceral fat area (VFA), fat mass index (FMI) and appendicular skeletal muscle mass index (ASMI) were recorded and compared between the two groups. Moreover, the actual exercise compliance of the exercise group was observed, along with any adverse events such as hypoglycemia or exercise-related injuries, as well as changes in antidiabetic medication dosage.Results:After the intervention, significant improvement was observed in both groups in all of the measurements, but with the average HbA1c, BMI, fat mass, VFA and FMI values of the exercise group then significantly better than the control group′s averages. The average compliance rate in the exercise group was 60%. No cases of hypoglycemia or exercise-related injuries were reported during the intervention, and there were no changes in the use of anti-diabetes medications.Conclusions:Exercise effectively improves glycemic control and physical indicators among community-dwelling T2DM patients. However, exercise compliance needs improving.
