OBJECTIVE: To explore the feasibility of using biomechanical indicators as supplementary evaluation to the Musculoskeletal Tumor Society Scoring System (MSTS) for amputee patients. METHODS: Twenty-four patients who underwent hemipelvectomy between September 2018 and January 2025 were enrolled. There were 15 males and 9 females with an average age of 61.4 years (range, 45-76 years). Participants performed gait tests at self-selected speeds using three assistive devices (prosthesis, single crutch, and double crutches). Motion data were analyzed using a customized OpenSim model. Biomechanical indicators of the intact limb exhibiting common characteristics were screened through correlation and sensitivity analyses. Test-retest reliability [interclass correlation coefficient (ICC)] of selected parameters was assessed to evaluate their potential as MSTS score supplements. RESULTS: All biomechanical indicators showed significant positive correlations with MSTS scores across assistive devices ( P<0.05). Seven indicators demonstrated |Pearson correlation coefficients|>0.8, including walking speed, maximum hip angle, maximum hip moment, peak hip flexion moment, peak hip extension moment, hip flexion impulse, and hip extension impulse. Among these, maximum hip moment, hip flexion impulse, and hip extension impulse exhibited significant between-group differences in adjacent MSTS levels ( P<0.05), indicating high sensitivity, along with excellent test-retest reliability (ICC>0.74, P<0.01). CONCLUSION Biomechanical indicators statistically qualify as potential supplements to MSTS scoring. Maximum hip moment, hip flexion impulse, and hip extension impulse demonstrate particularly high sensitivity to MSTS score variations.

Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Objective:To investigate the effect of type 2 taste receptor(T2R)38 activation on ferroptosis of human airway epithelium NuLi-1 cells induced by cigarette smoke exposure,and to clarify its possible mechanism.Methods:The human airway epithelial NuLi-1 cells were divided into control group(without any treatment),cigarette smoke extract(CSE)group(treated with 5％CSE for 24 h)and CSE+T2R38 specific agonist phenylthiocarbamide(PTC)group(CSE+PTC group)(treated with 5％CSE and 1 mmol·L-1 PTC for 24 h).The expression levels of T2R38 mRNA and protein in NuLi-1 cells in various groups were determined by real-time fluorescence quantitative PCR(RT-qPCR)and Western blotting methods.The cell viabilities in various groups were determined by cell counting kit-8(CCK-8)assay.The activities of inducible nitric oxide synthase(iNOS),endothelial nitric oxide synthase(eNOS),and superoxide dismutase(SOD)in the cells in various groups were measured by kits.DAX-J2 red fluorescence probe was used to determine the levels of nitric oxide(NO)in the cells in various groups.The reactive oxygen species(ROS)levels in the cells in various groups were detected by fluorescent probe kit.The levels of malondialdehyde(MDA),Fe2+,and reduced glutathione(GSH)in the cells in various groups were determined by enzyme-linked immunosorbent assay(ELISA)method.Western blotting method was used to determine the expression levels of nuclear factor erythroid 2-related factor 2(Nrf2)and glutathione peroxidases 4(GPx4)proteins in the cells in various groups.Results:Compared with control group,the expression levels of T2R38 mRNA and protein in NuLi-1 cells in CSE group were increased(P＜0.05).Compared with control group,the viability of NuLi-1 cells in CSE group was decreased(P＜0.05),the activities of iNOS and SOD in cells in CSE group were increased(P＜0.05),the levels of NO and ROS were increased(P＜0.05),the levels of MDA and Fe2+were increased(P＜0.05),and the GSH level and the expression levels of Nrf2 and GPx4 proteins were decreased.Compared with CSE group,the viability of NuLi-1 cells in CSE+PTC group was increased(P＜0.05),the activity of SOD and the GSH level in the cells were increased(P＜0.05),the activity of iNOS in cells was decreased(P＜0.05),the levels of NO and ROS in cells were decreased(P＜0.05),the levels of MDA and Fe2+were decreased(P＜0.05),and the expression levels of Nrf2 and GPx4 proteins were increased(P＜0.05).There was no significant difference in eNOS activity among control group,CSE group,and CSE+PTC group(P＞0.05).Conclusion:Activation of bitter taste receptor T2R38 can inhibit ferroptosis in human airway epithelium NuLi-1 cells induced by cigarette smoke exposure,and its mechanism may be related to the reduction of iNOS activity in the cells.

ConclusionModified Dahuang Huanglian Xiexintang may inhibit mitochondrial autophagy and promote the browning of visceral adipose tissue through the HIF-1α/BNIP3/LC3B pathway， thereby improving glucose and lipid metabolism in obese T2DM rats.

Type 2 diabetes mellitus （T2DM） is based on insulin resistance （IR） and insulin secretion deficiency， with the specific mechanisms still unclear. Current research involves mechanisms such as glycolipid toxicity， inflammatory response， oxidative stress damage， and mitochondrial dysfunction. Modern traditional Chinese medicine （TCM） scholars have named it "blood glucose collateral disease" based on the clinical characteristics and natural progression of T2DM. This condition is primarily manifested as abnormal blood sugar levels in the early stages， and as the disease progresses， it gradually causes widespread damage to the body's veins and collaterals， ultimately leading to lesions in vessels and collaterals. Among these， "spleen heat" （obesity type） is the most common clinical type of T2DM. The concept of "internal heat-induced elimination" runs through both the onset and complications of T2DM， with internal heat being a key factor in its pathogenesis. The clinical application of Dahuang Huanglian Xiexintang and its modifications has achieved significant therapeutic effects. This paper reviews the origins and treatment characteristics of Dahuang Huanglian Xiexintang， along with clinical application research and experimental studies related to T2DM treatment， involving mechanisms for regulating glucose and lipid metabolism disorders， improving IR， modulating inflammatory responses， combating oxidative stress damage， regulating autophagy-related signaling pathways， modulating intestinal flora， inhibiting pyroptosis， and alleviating endoplasmic reticulum stress， with the purpose to provide direction for further research on the prevention and treatment of T2DM and its related complications， to offer reference for developing Dahuang Huanglian Xiexintang as a rapid hypoglycemic Chinese patent medicine for obese T2DM， and to better guide the clinical promotion of this drug.

BACKGROUND:Clinical skin wound healing continues to be a significant concern,and tissue repair research has moved to the forefront with the development of biomaterials with immunomodulatory properties.Therefore,it is crucial to research wound dressings that have immunomodulatory properties. OBJECTIVE:To prepare chitosan hydrogels that have been modified by arginine with different configurations and assess their capacity to speed up wound healing in a rat animal model. METHODS:(1)In vitro trial:Chitosan modified by pure L-arginine,pure D-arginine,and L-arginine and D-arginine was synthesized by EDC/NHS system,which was then crosslinked with aldehyde-modified four-arm polyethylene glycol.Different chitosan-based hydrogels(CS-L,CS-D,and CS-DL)were finally formed via the Schiff base reaction.Three kinds of hydrogel extracts were co-cultured with fibroblasts respectively.Hydrogel cytocompatibility was assessed using the CCK-8 assay and live/dead staining.The effect of hydrogel on the migration capacity of fibroblasts was assessed by using a scratch test.Three kinds of hydrogels were incubated with rat erythrocyte suspension respectively to evaluate the hemocompatibility of the hydrogels.The hydrogel extract was co-cultured with RAW264.7 macrophages to test the hydrogels'capacity to enhance macrophage NO generation and polarize macrophage phenotype.(2)In vivo experiment:A total of 36 adult SD rats were divided into 4 groups with 9 rats in each group by the random number table method.Two full-layer skin defect wounds of 2 cm×2 cm were made on the back of each rat.Normal saline was added to the wounds of the control group,and corresponding hydrogel was added to the wounds of the CS-L,CS-D,and CS-DL groups,respectively,and then bandaged and fixed.The wound healing was observed regularly after operation.Hematoxylin-eosin staining was performed at 3,10,and 21 days after operation.The samples were collected 10 days after operation and M2 macrophage immunofluorescence staining was performed. RESULTS AND CONCLUSION:(1)In vitro experiments:Under scanning electron microscopy,the three kinds of hydrogels exhibited obvious interpenetrating network structures with pore sizes ranging from 70-200 μm.The three kinds of hydrogels have good swelling performance,degradation performance,self-healing performance,and suitable mechanical strength.The three kinds of hydrogels had good cytocompatibility and hemocompatibility and could promote the migration of fibroblasts.All three kinds of hydrogels had the ability to promote the polarization of macrophages,and CS-D hydrogels had the strongest ability to promote the polarization of macrophages.CS-L hydrogel could significantly promote the production of NO in macrophages.(2)In vivo experiment:3 and 10 days after operation,the wound healing rate in the CS-L and CS-D groups was higher than that in the control group(P<0.05).After 21 days,the wound healing rate of the three hydrogel groups was higher than that of the control group.Hematoxylin-eosin staining displayed that a large number of inflammatory cells were infiltrated in the wound tissue of rats in all groups,accompanied by neovessels and fibroblasts 3 days after operation.10 days after operation,there was still more inflammatory cell infiltration in the wound of the control group,and the inflammation of the other three groups was improved,especially the decrease of inflammatory cells in the CS-D group was more obvious.21 days after operation,the wound epithelium of each group was well repaired,and there was basically no inflammatory cell infiltration in the CS-L and CS-D groups,while there was still a small amount of inflammatory cell infiltration in the control group.Immunofluorescence staining revealed that the number of M2-type macrophages in the CS-D group was higher than that in the other three groups(P<0.05).(3)The results conclude that chitosan hydrogels modified by different configurations of arginine can promote wound healing through different mechanisms.

BACKGROUND:Distal tibial tuberosity-high tibial osteotomy is a surgical treatment for knee osteoarthritis,but there is still a lack of clinical studies on its effect on ankle joints. OBJECTIVE:To observe the effects of distal tibial tuberosity-high tibial osteotomy on ankle angle on coronal plane of the radiography of the full length of lower limb in weight loading. METHODS:Data of 40 patients(41 knees)with distal tibial tuberosity-high tibial osteotomy from March 2021 to March 2022 were retrospectively analyzed,including 31 females and 9 males,20 left knees and 21 right knees,aged 49-75 years,mean(63.44±6.57)years.The radiographic data of the full length of the lower limb in weight loading were collected before,week 2 and week 48 postoperatively.Hip-knee-ankle angle,talar tilt angle,tilt angle of the ankle,tibiocrural angle,and tibial articular surface angle were measured before and after surgery. RESULTS AND CONCLUSION:(1)Hip-knee-ankle angle improved from(-6.24±3.69)° before operation to(2.59±3.49)° week 2 postoperatively and(2.15±3.49)° week 48 postoperatively.The tilt angle of the ankle changed from(-7.90±3.11)° before operation to(-2.51±2.59)° week 2 postoperatively and(-2.46±2.42)° week 48 postoperatively,with statistically significant difference(P<0.001).(2)There was no significant difference in talar tilt angle,tibiocrural angle,and tibial articular surface angle before and week 2 postoperatively.(3)No significant difference in the angle changes was detected between week 2 and week 48 postoperatively.(4)It is indicated that distal tibial tuberosity-high tibial osteotomy can not only correct genu varus but also improve ankle angle.This result remains stable after 48 weeks of weight-bearing activities.

ObjectiveTo investigate the effect of Tangzhi pills on the improvement of insulin resistance （IR） in the liver with type 2 diabetes （T2DM） by regulating phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway based on differential genes and its possible molecular mechanism. MethodT2DM rat models were prepared by high fat （HFD） diet combined with streptozotocin （STZ） intraperitoneal injection. The experiment was divided into blank group， model group， metformin hydrochloride group （0.18 g·kg^-1）， Tangzhi pills high （1.08 g·kg^-1）， medium （0.54 g·kg^-1） and low （0.27 g·kg^-1） dose groups. Rat serum， liver， and pancreatic tissue were collected， and the pathological tissue of the liver and pancreas was observed using hematoxylin-eosin （HE） staining. The fasting blood glucose level （FBG） was detected， and oral glucose tolerance （OGTT） tests were conducted. Enzyme-linked immunosorbent assay （ELISA） was used to detect fasting serum insulin （FINS） and glycated hemoglobin （GHb） levels in rats. IR homeostasis model index （HOMA-IR）， β cellular homeostasis index （HOMA-β）， and insulin sensitivity index （ISI） were calculated. Biochemical methods were used to determine the levels of triglyceride （TG）， total cholesterol （TC）， low-density lipoprotein （LDL-C）， and high-density lipoprotein （HDL-C） in rat serum. Transcriptomics obtained differentially expressed mRNA from liver tissue and enriched differentially expressed pathways. Real-time reverse transcriptase polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of cyclic adenylate responsive element binding protein 3-like protein 2 antibody （CREB3l2）， B-lymphocyte tumor 2 （Bcl-2）， Toll-like receptor 2 （TLR2）， cyclin-dependent kinase inhibitor 1A （CDNK1A）， and DNA damage induced transcription factor 4-like protein （DDIT4） in liver tissue. Western blot was used to detect the protein expression of phosphorylated phosphatidylinositol 3-kinase （p-PI3K）， phosphorylated protein kinase B （p-Akt）， glucose transporter 4 （GLUT4）， insulin receptor （INSR）， and insulin receptor substrate 2 （IRS2）. ResultThe pharmacodynamic experiment results showed that compared with model group， Tangzhi pills groups repaired liver and pancreatic tissue to varying degrees， reduced blood sugar （P<0.01）， and promoted a decrease in serum FINS， GHb， and HOMA-IR （P<0.05， P<0.01）. In addition， HOMA-β and ISI increased （P<0.05， P<0.01）. The levels of TC， TG， and LDL-C decreased （P<0.05， P<0.01）， while the levels of HDL-C increased （P<0.05， P<0.01）. The transcriptomics experimental results confirmed that the PI3K/Akt signaling pathway was significantly expressed in both the blank group and model group， as well as in the high-dose Tangzhi pills group and model group. CDNK1A， DDIT4， CREB3l2， Bcl-2， and TLR2 were significantly differentially expressed mRNA during TG intervention in T2DM. Compared with the model group， the protein expression of p-PI3K， p-Akt， GLUT4， INSR， and IRS2 increased in all Tangzhi pills groups （P<0.01）. The mRNA expression of CREB3l2， Bcl-2， and TLR2 increased （P<0.01）， while that of CDNK1A and DDIT4 decreased （P<0.01）. ConclusionTangzhi pills may regulate the PI3K/Akt signaling pathway based on the differential mRNA expression of CREB3l2， Bcl-2， TLR2， CDNK1A， and DDIT4， thereby improving IR in the liver with T2DM.
