Objective To explore the mechanism of Taohong Siwu Decoction in recovering joint muscle strength and bone mineral density(BMD)in patients after hip preservation surgery for osteonecrosis of the femoral head(ONFH).Methods A total of 110 ONFH patients admitted to Guang'anmen Hospital Baoding Branch,China Academy of Chinese Medical Sciences from April 2022 to April 2024 were enrolled.The patients were equally randomized into a control group and a study group using a random number table,with 55 cases in each group.All patients underwent core decompression surgery and then were given postoperative conventional western medical treatment,and the study group received additional modified Taohong Siwu Decoction.The course of treatment lasted for 8 weeks.Before and after treatment,the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome scores,Visual Analogue Scale(VAS)score for pain,Harris hip score,joint muscle strength,bone mineral density(BMD),hemorheological parameters(including plasma viscosity,whole blood high-shear viscosity,and whole blood low-shear viscosity),and bone metabolism markers[including alkaline phosphatase(ALP),osteocalcin(BGP),and bone morphogenetic protein 2(BMP-2)].After treatment,the clinical efficacy was evaluated between groups.Results(1)After 8 weeks of treatment,the total effective rate in the study group was 92.73%(51/55),which was significantly higher than that in the control group(72.73%,40/55).The intergroup comparison showed a statistically significant difference(χ2=7.698,P＜0.01).(2)After treatment,scores for hip pain,soreness and weakness of the lower back and knees,mental fatigue,and deep-thin-choppy pulse decreased in both groups compared with those before treatment(P＜0.05).Moreover,the magnitude of reduction in all these scores was significantly greater in the study group than that in the control group(P＜0.01).(3)After treatment,the VAS scores for pain severity decreased in both groups compared with baseline(P＜0.05),while the Harris scores for joint function increased in both groups(P＜0.05).Furthermore,the magnitude of reduction in VAS scores and the magnitude of improvement in Harris scores were both significantly greater in the study group than those in the control group(P＜0.01).(4)After treatment,plasma viscosity,high-shear whole blood viscosity,and low-shear whole blood viscosity decreased in both groups compared with those before treatment(P＜0.05).Additionally,the reductions in all these parameters were significantly more pronounced in the study group than in the control group(P＜0.01).(5)After treatment,serum alkaline phosphatase(ALP)levels decreased in both groups(P＜0.05),while serum osteocalcin(BGP)and bone morphogenetic protein-2(BMP-2)levels increased in both groups(P＜0.05).Crucially,the magnitude of reduction in serum ALP levels and the magnitude of elevation in serum BGP and BMP-2 levels were all significantly greater in the study group than those in the control group(P＜0.01).(6)After treatment,in the study group,the number of patients with Grade 3 muscle strength significantly decreased while the number with Grade 4 muscle strength significantly increased compared with those before treatment(P＜0.05).In contrast,although the control group showed some improvement in joint muscle strength,the changes were not statistically significant(P＞0.05).After treatment,the intergroup comparisons showed that the study group had a significantly smaller number of patients with Grade 3 muscle strength and a significantly larger number with Grade 4 muscle strength than the control group(P＜0.01).(7)After treatment,both local femoral head BMD and average BMD increased in both groups compared with those before treatment(P＜0.05).The magnitude of increase in both local and average BMD was significantly greater in the study group than that in the control group(P＜0.01).Conclusion The application of Taohong Siwu Decoction in the treatment of in patients after hip preservation surgery for ONFH is effective on reducing TCM syndrome scores,alleviating pain,improving joint function and hemorheology,and restoring BMD and bone metabolism indicators,which enhances the overall clinical efficacy for the patients.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription （JPHGP） in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head （SONFH） by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal， model， low-， medium-， and high-dose （2.5， 5， 10 g·kg^-1， respectively） JPHGP， and Jiangushengwan （1.53 g·kg^-1） groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg^-1 on days 1 and 2， and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg^-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection， and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head， and the number of adipocytes， the rate of empty bone lacunae， and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride （TG）， total cholesterol （TC）， low-density lipoprotein （LDL）， high-density lipoprotein （HDL）， apolipoprotein A1 （ApoA1）， and apolipoprotein B （ApoB）. At the same time， the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed， and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking， immunohistochemistry， and Western blot. ResultsCompared with the normal group， the model group showcased thinning of the femoral head， trabecular fracture， karyopyknosis， subchondral cystic degeneration， increases in the number of adipocytes and the rate of empty bone lacunae （P<0.01）， a reduction in the trabecular area （P<0.01）， decreases in BMD， Tb.Th， Tb.N， and BV/TV， and increases in Tb.Sp and BS/BV （P<0.01）. Compared with the model group， the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae， an increase in the trabecular area （P<0.05， P<0.01）， rises in BMD， Tb.Th， Tb.N， and BV/TV， and decreases in Tb.Sp and BS/BV （P<0.05， P<0.01）. Compared with the normal group， the model group showcased raised serum levels of TG， TC， LDL， and ApoB and lowered serum levels of HDL and ApoA1 （P<0.01）. Compared with the model group， the JPHGP groups had lowered serum levels of TG， TC， LDL， and ApoB （P<0.05， P<0.01） and a risen serum level of ApoA1 （P<0.05， P<0.01）. Moreover， the serum level of HDL in the high-dose JPHGP group increased （P<0.01）. A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head， and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation， lipids， apoptosis， and osteoclast differentiation. Molecular docking， immunohistochemistry， and Western blot results showed that compared with the normal group， the model group displayed increased content of 5-lipoxygenase （5-LO） and peroxisome proliferator-activated receptor γ （PPARγ） in the femoral head （P<0.01）. Compared with the model group， medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ （P<0.05， P<0.01）. ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.

Objective:To study the distribution characteristics of current patients with Kashin-Beck disease (KBD) in Molidawa Daur Autonomous Banner (referred to as Morin Banner), and provide suggestions for service management.Methods:Information of KBD current patients in Morin Banner was collected from January 1, 2018 to June 30, 2024 using the "KBD Current Patient Survey System" provided by the Center for Endemic Disease Control, Chinese Center for Disease Control and Prevention. A descriptive study method was used to analyze the basic information and clinical data of current patients.Results:As of June 30, 2024, a total of 6 223 KBD current patients were reported in Morin Banner, and the patients were distributed in 15 townships (towns). There was a statistically significant difference in the prevalence rate of KBD among different townships (towns, χ 2 = 3 069.01, P < 0.001). The minimum age of the KBD current patients was 27 years old, and the maximum was 98 years old, mainly concentrated in the age range of 45 - 74 years old, accounting for 95.7% (5 954/6 223). There was a significant difference in the prevalence rate of KBD among different age groups (χ 2 = 5 912.76, P < 0.001). The male to female ratio was 1.00∶1.14 (2 910 ∶ 3 313), and there was a statistically significant difference in prevalence rate of KBD between genders(χ 2 = 44.38, P < 0.001). The KBD current patients mainly had a primary school education, married, and farmers, accounting for 59.2% (3 685/6 223), 89.8% (5 590/6 223), 93.2% (5 802/6 223), respectively; and the clinical grading of patients is mainly degree Ⅰ. There was a statistically significant difference in the rate of limb disability among patients with different clinical grades (χ 2 = 64.26, P < 0.001). The rate of limb disability in males was higher than that in females (χ 2 = 10.36, P = 0.001). Conclusions:The KBD current patients in Morin Banner are distributed in various township (town), with middle-aged and elderly famers being the main ones. It is necessary to strengthen monitoring of KBD, and pay attention to personalized treatment and management of KBD current patients.

Viral myocarditis(VMC)is a type of myocarditis caused by Coxsackievirus B3(CVB3)infection.Its pathogenesis is complex that includes direct viral action,host immune and inflammatory response,myocardial structure and function remodeling.The therapeutic effect of single target drugs is limited,while traditional Chinese medicine not only has antiviral effects,but also demon-strates systematic advantages in intervening in VMC due to its"multi-component,multi-target,and multi-pathway"characteristics.This article reviews the pathogenic mechanisms of CVB3-induced VMC,clarifies the interaction between CVB3 and host cells,and ex-plores the intervention mechanisms and developments of traditional Chinese medicine interventions for CVB3-induced VMC.At the same time,the prospects of traditional Chinese medicine treatment for CVB3-induced VMC in this study suggest that future research should strengthen the analysis of multi-target synergistic mechanisms based on traditional Chinese medicine formulas,combine artifi-cial intelligence,genomics,and gene editing technologies to predict drug-target interaction networks,establish standardized and per-sonalized system for integrated traditional Chinese and Western medicine treatment plans,and provide more effective strategies for the prevention and treatment of VMC.

Objective:To investigate the relationship between terminal soft tissue infection of the diabetic foot and glucose and lipid metabolism as well as inflammatory factors.Methods:A total of 126 patients with diabetes mellitus combined with foot-soft tissue infections, who hospitalized in our hospital from March 2018 to February 2023 were divided into mild group (46 cases), moderate group (43 cases) and severe infections group (37 cases) according to the degree of foot-soft tissue infection before treatment. The glucose and lipid metabolism and inflammatory factors of patients among the different groups were compared, and the effects of glycolysis and lipid metabolism and inflammatory factors on the soft tissue infection at the end of diabetic foot were analyzed by logistic regression analysis. Patients were treated with antimicrobial therapy and other treatments. After 2 weeks of anti-infective treatment, if three consecutive cultures of secretions were negative for bacteria, antibiotic therapy was discontinued and glucose-lipid metabolism and inflammatory factors after treatment were compared. Patients were followed up for 1 year, and the changes in glucose-lipid metabolism and inflammatory factors were observed in toe or limb amputations group ( n=38) and non-toe or limb amputations group ( n=88). Results:Before treatment, the levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), free fatty acids (FFA), fasting plasma glucose (FPG), fasting insulin (FINS), glycosylated hemoglobin typeA1c (HbA 1c), vascular cell adhesion molecule-1 (VCAM-1), C reactive protein (CRP,) tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) in the mild group were significantly lower than those in the moderate and severe group, and the adiponectin (APN) level was significantly higher than that in the moderate and severe group (all P<0.05). Logistic regression analysis showed that FFA, FPG, FINS, APN, VCAM-1, CRP, TNF-α and IL-6 were risk factors of terminal soft tissue infection ( P<0.05). After treatment, the levels of TC, LDL-C, FFA, FPG, FINS, HbA1c, VCAM-1, CRP, TNF-α and IL-6 were significantly decreased, and the APN was significantly increased (all P<0.05). The levels of TC, LDL-C, FFA, FPG, FINS, HbA1c, VCAM-1, CRP, TNF-α, and IL-6 were significantly higher in the toe/limb amputation group than in the non-toe/limb amputation group, and the APN levels were significantly lower in the toe/limb amputation group than in the non-toe/limb amputation group (all P<0.05). Conclusion:There is a close relationship between glucose and lipid metabolism, inflammatory factors and terminal soft tissue infection of the diabetic foot.

Objective:To explore the effect of specific inhibitor of Smad3 (SIS3) on glucocorticoid-induced ocular hypertension in mice and its possible mechanism.Methods:Fifty-one eight-week-old female C57BL/6J mice were randomly divided into control group, dexamethasone group and SIS3 group by the random number table method, with 17 mice in each group.Mice in the control group were injected with 20 μl 2 % polyvinyl alcohol into the conjunctival fornix every week for 4 weeks.Mice in the dexamethasone group and SIS3 group were injected with 20 μl 10 mg/ml dexamethasone acetate every week and SIS3 group was treated with additional 100 μg/ml SIS3 nanomicelle eye drops 3 times daily for up to 4 weeks.Intraocular pressure (IOP) was measured weekly using Icare rebound tonometer.Mice were sacrificed 4 weeks after treatment, and the eyeballs were removed.Morphology of trabecular meshwork (TM) tissues were detected by hematoxylin-eosin (HE) staining.The collagen deposition area in TM tissues were examined by Masson staining.Fibronectin (FN) and collagen type Ⅰ (Col-1) in the extracellular matrix of TM tissue were detected by immunofluorescence staining.TM tissues were obtained from donated patients, and primary human trabecular meshwork cells (HTMCs) were obtained by culture.The expression level of myocilin in dexamethasone-induced HTMCs was detected by immunofluorescence and Western blot for cell identification.Primary HTMCs were divided into normal control group, dexamethasone group and SIS3 group cultured with normal culture medium, medium containing 400 nmol/L dexamethasone, medium containing 400 nmol/L dexamethasone+ 10 μmol/L SIS3 for 48 hours, respectively.The expression levels of FN, Col-1 and p-Smad3/Smad3 proteins were measured by Western blot.The use and care of animals complied with the ARVO statement.This study protocol was approved by the Animal Ethics Committee of Zhengzhou University (No.ZZU-LA20220729).The collection of TM tissue specimens complied with the Declaration of Helsinki and was approved by the Medical Ethics Committee of Henan Provincial Eye Hospital (No.HNEECKY-2022[18]).The patients knew the purpose of the experiment and signed the informed consent forms.Results:There was a significant overall difference in IOP among the three groups at different time points after administration ( Fgroup=72.94, P<0.001; Ftime=33.19, P<0.001).Compared with baseline, IOP was increased in the dexamethasone group at each time point after administration, and the differences were statistically significant (all P<0.001).The IOP of the control and SIS3 groups at weeks 1, 2, 3, 4 were significantly lower than that of the dexamethasone group (all P<0.001).HE staining showed that the iridocorneal angles of all groups were open with similar morphology of the TM structure.Masson staining showed that the positive expression area of collagen in the control group, dexamethasone group and SIS3 group was (9.57±2.91)%, (27.75±5.88)% and (11.67±3.78)%, respectively, with a statistically significant difference among the three groups ( F=25.91, P<0.001), and the positive expression area of collagen was significantly lower in the control group and SIS3 group than in the dexamethasone group (all P<0.001).The fluorescence expression level of FN in the control group, dexamethasone group and SIS3 group was 8.00±1.92, 14.01±2.74 and 7.85±0.64, respectively, and the fluorescence expression level of Col-1 was 6.90±1.16, 14.36±3.19 and 4.90±0.88, respectively, with statistically significant differences among the three groups ( F=15.93, 30.29; both P<0.001), and the fluorescence expression levels of FN and Col-1 were significantly lower in the control group and SIS3 group than in the dexamethasone group (all P<0.01).Immunofluorescence staining and Western blot showed that the cultured primary cells expressed myocilin and the expression level of myocilin was significantly increased after dexamethasone induction, which was identified as HTMCs.There were statistically significant differences in the relative expression levels of FN, Col-1, and p-Smad3/Smad3 proteins among different groups of cells ( F=8.22, 23.08, 8.78; all P<0.05), and the relative expression levels of FN, Col-1, and p-Smad3/Smad3 proteins were significantly lower in the control group and SIS3 group than in the dexamethasone group (all P<0.05). Conclusions:SIS3 reduces IOP by inhibiting p-Smad3, reducing extracellular matrix deposition in TM, and reducing fibrosis in the TM tissue.
