BACKGROUND:Some studies have found that ferroptosis of osteoblasts can be an important mechanism to induce the occurrence and development of hormone-induced femoral head necrosis.With the development of Chinese medicine,some scholars have found that some Chinese medicine monomer,Chinese medicine compound and Chinese patent medicine can regulate the ferroptosis of osteoblasts through various pathway mechanisms,and finally play a role in the treatment of steroid-induced avascular necrosis of femoral head. OBJECTIVE:To investigate the relationship between ferroptosis and steroid-induced avascular necrosis of femoral head and the mechanism of Chinese medicine regulating ferroptosis of osteoblasts in the treatment of steroid-induced avascular necrosis of femoral head,so as to provide new ideas for the diagnosis and treatment of steroid-induced avascular necrosis of femoral head. METHODS:With"ferroptosis,steroid-induced avascular necrosis of femoral head,osteoblast,Chinese herbal medicine,glucocorticoid,iron metabolism,reactive oxygen species,glutathione peroxidase"as Chinese search terms,and"ferroptosis,hormonal necrosis of the femoral head,osteoblast,Chinese herbal medicine,glucocorticoid,iron metabolism,ROS,GPX4"as English search terms,the search was conducted on CNKI,PubMed,WanFang,VIP and other databases.The relevant articles on osteoblast ferroptosis and steroid-induced avascular necrosis of femoral head and the regulation of Chinese herbal medicine intervention from the establishment of each database to 2023 were screened.Finally,76 articles were systematically analyzed. RESULTS AND CONCLUSION:(1)Ferroptosis of osteoblasts plays an important role in the pathogenesis of steroid-induced avascular necrosis of femoral head.(2)The occurrence of ferroptosis in osteoblasts is regulated by a variety of mechanisms,such as intracellular iron overload causing ferroptosis.Lipid peroxidation damages cell membrane and causes ferroptosis.Cystine/glutamate reverse transporter induced ferroptosis by influencing glutathione level and glutathione peroxidase 4 activity.Fenton reaction in the cell produces a large number of reactive oxygen species and causes ferroptosis.(3)Chinese medicine monomer icariin,Chinese medicine compound Qinge pills and Chinese patent medicine Bushen Huoxue granules can regulate the occurrence of osteoblast ferroptosis,and help to prevent and treat steroid-induced avascular necrosis of femoral head.(4)The mechanism of ferroptosis in osteoblasts is still unclear.Further investigation on the mechanism of action of both is expected to provide a new choice for clinical treatment of steroid-induced avascular necrosis of femoral head.

Objective:
To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures.
Methods:
From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children.
Results:
The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05).
Conclusion
Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

This study aims to investigate the effect of salvianolic acid B (Sal B), the active ingredient of Salvia miltiorrhiza, on H9C2 cardiomyocytes injured by oxygen and glucose deprivation/reperfusion (OGD/R) through regulating mitochondrial fission and fusion. The process of myocardial ischemia-reperfusion injury was simulated by establishing OGD/R model. The cell proliferation and cytotoxicity detection kit (cell counting kit-8, CCK-8) was used to detect cell viability; the kit method was used to detect intracellular reactive oxygen species (ROS), total glutathione (t-GSH), nitric oxide (NO) content, protein expression levels of mitochondrial fission and fusion, apoptosis-related detection by Western blot. Mitochondrial permeability transition pore (MPTP) detection kit and Hoechst 33342 fluorescence was used to observe the opening level of MPTP, and molecular docking technology was used to determine the molecular target of Sal B. The results showed that relative to control group, OGD/R injury reduced cell viability, increased the content of ROS, decreased the content of t-GSH and NO. Furthermore, OGD/R injury increased the protein expression levels of dynamin-related protein 1 (Drp1), mitofusions 2 (Mfn2), Bcl-2 associated X protein (Bax) and cysteinyl aspartate specific proteinase 3 (caspase 3), and decreased the protein expression levels of Mfn1, increased MPTP opening level. Compared with the OGD/R group, it was observed that Sal B had a protective effect at concentrations ranging from 6.25 to 100 μmol·L-1. Sal B decreased the content of ROS, increased the content of t-GSH and NO, and Western blot showed that Sal B decreased the protein expression levels of Drp1, Mfn2, Bax and caspase 3, increased the protein expression level of Mfn1, and decreased the opening level of MPTP. In summary, Sal B may inhibit the opening of MPTP, reduce cell apoptosis and reduce OGD/R damage in H9C2 cells by regulating the balance of oxidation and anti-oxidation, mitochondrial fission and fusion, thereby providing a scientific basis for the use of Sal B in the treatment of myocardial ischemia reperfusion injury.

This study explored the ideas and methods of acupuncture for Guillain-Barré Syndrome (GBS) with the core principle of “to treat flaccidity, select the yangming (阳明) channel only”. The main pathological mechanism of GBS is deficiency of qi and blood in the yangming channel, malnutrition of all sinews, diminished spleen and stomach function leading to the production of pathogenic damp-heat qi, which obstructs the meridians, and gradually affects the liver and kidneys, consuming essence and damaging blood. Concurrently, dysfunction of the dumai (督脉) pivotal mechanism and lack of moisture in sinews and vessels result in symptoms such as skin numbness, paralysis, and muscle wastage. In clinical diagnosis and treatment, a combination of syndrome and channel differentiation is taken. Treatment primarily focuses on acupoints of yangming channel, aiming to supplement qi and blood, and acupoints of du mai are combined to open the vessel and fill the marrow. Specific acupoints are selected based on syndrome differentiation, providing comprehensive regulation to promote harmonization of qi and blood, relieve meridians, and the smooth generation and circulation of whole body fluids. This, in turn, enhances the strength of muscles and bones, and fosters a robust and freely moving body.

Objective:To analyze the feasibility and advantages of gastric triangle suspension technique in laparoscopic radical anterograde modular pancreatiplenectomy (L-RAMPS) for patients of pancreatic body and tail malignant tumor.Methods:The clinical data of 29 patients with L-RAMPS in Li Huili Hospital of Ningbo Medical Center from January 2019 to October 2023 were retrospectively analyzed, including 14 males and 15 females, aged (67.6±7.5) years. According to whether gastric triangle suspension was used during operation, 29 patients were divided into suspension group ( n=14) and control group ( n=15). The two groups were compared with several indexes of body mass index, tumor length, postoperative pathological type, operation time, intraoperative blood loss, intraoperative incision margin, intraoperative blood transfusion, pancreatic fistula, postoperative massive bleeding, postoperative gastroparesis, length of hospital stay and so on. Results:There were no significant differences in age, sex, body mass index, tumor length and pathological type between the two groups (all P>0.05). Postoperative pathologic findings of the 29 patients included 21 cases of pancreatic adenocarcinoma (72.4%), 2 cases of intraductal papillary mucinous tumors (6.9%), 2 cases of pancreatic neuroendocrine tumors (6.9%), 1 case of pancreatic adenosquamous carcinoma (3.4%), and 3 cases of mucinous cystadenocarcinoma (10.3%). There was no significant difference in the proportion of positive first incision margin, intraoperative blood transfusion, postoperative B/C pancreatic fistula, postoperative massive hemorrhage and postoperative gastroparesis between the two groups (all P>0.05). The operative time and intraoperative blood loss in the suspension group were (200.3±13.5) min and (148.6±42.2) ml respectively, less than that in the control group (223.5±36.3) min and (205.3±63.3) ml, and the hospital stay in the suspension group was 14 (12, 17) d, shorter than that in the control group 26 (17, 32) d. The differences were statistically significant (all P<0.05). Conclusion:Gastric triangle suspension in L-RAMPS for patients of pancreatic body and tail malignant tumor can reduce the amount of intraoperative bleeding, shorten the operation time and hospital stay, is a reliable and simple suspension method.
