BACKGROUND:Chronic rotator cuff injury is often companied by tendon degeneration and impaired function of tendon-derived stem cells.As am important cytokine,platelet-derived growth factor-DD has a regulatory effect on the proliferation and differentiation of tendon-derived stem cells.OBJECTIVE:To investigate the effect of platelet-derived growth factor-DD on the proliferation and multilineage differentiation of tendon-derived stem cells in human chronic rotator cuff injury.METHODS:Tendon-derived stem cells were isolated from human chronic rotator cuff injury tissue and cultured in vitro.Immunofluorescence staining was used to observe the cytoskeletal morphology of tendon-derived stem cells.Flow cytometry was used to identify the phenotype of tendon-derived stem cells.Tendon-derived stem cells were divided into two groups.The control group did not receive any intervention.The platelet-derived growth factor-DD group was treated with 5 μg/mL platelet-derived growth factor-DD.The effect of platelet-derived growth factor-DD on the proliferation and multilineage differentiation of tendon-derived stem cells was evaluated by cell proliferation assay and three-lineage differentiation assay.RESULTS AND CONCLUSION:(1)The number of EdU-positive cells in the platelet-derived growth factor-DD group was significantly increased compared with the control group(P＜0.05).Tendon-derived stem cells entered the rapid proliferation phase earlier,and the cell growth was logarithmic.(2)The positive areas of Oil Red O staining,Alcian Blue staining,and Alizarin Red staining in the platelet-derived growth factor-DD group were significantly larger than those in the control group(P＜0.05).(3)The above results show that platelet-derived growth factor-DD significantly promotes the proliferation and adipogenic,osteogenic,and chondrogenic differentiation of tendon-derived stem cells.

ObjectiveTo investigate the effects of Shenxiong Huanglian Jiedu decoction on the clearance of amyloid β-protein （Aβ） and neuronal damage in the mouse model of Alzheimer's disease （AD）. MethodsA total of 36 SPF-grade 2-month-old C57BL/6J mice were used in this study， and the modeling was performed by bilateral hippocampal injection of Aβ oligomers in C57BL/6J mice. The experiment was conducted with a blank group， a sham operation group， a model group， low- and high-dose （3.27，6.54 g·kg^-1， respectively） Shenxiong Huanglian Jiedu decoction groups， and a positive control （donepezil hydrochloride， 0.65 mg·kg^-1） group. At the end of the drug intervention， the learning and memory abilities and the activities of mice were evaluated by the Morris water maze and open field tests. Brain histopathology was examined by hematoxylin-eosin and Nissl staining. Additionally， in vivo imaging was employed to measure the metabolism of fluorescent Aβ in the cerebrospinal fluid， and staining of ionized calcium-binding adapter molecule-1 （Iba-1） was employed to assess microglial activation in the hippocampal tissue. Additionally， neurotrophin-3 （NT-3） and brain-derived neurotrophic factor （BDNF） levels in the brain tissue and serum were determined by the immunofluorescence assay and enzyme-linked immunosorbent assay. Western blot was conducted to determine the expression of inflammation and pathway-related proteins in the hippocampal tissue. ResultsCompared with the blank group and the sham operation group， the escape latency of the mice in the model group was prolonged， the platform residence time was shortened， the hippocampal tissue showed pathological manifestations such as neuronal pyknosis， Nissl body dissolution， and microglia activation. The metabolic rate of fluorescent Aβ through cerebrospinal fluid was slowed down， and the expression levels of BDNF， NT-3， and interleukin-10 （IL-10） in the hippocampus were significantly decreased （P<0.01）. The expression levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， Toll-like receptor 4 （TLR4）， myeloid differentiation factor 88 （MyD88） and phosphorylated nuclear transcription factor-κB （p-NF-κB p65） in hippocampus were significantly increased （P<0.05， P<0.01）. Compared with the model group， the escape latency of mice in the low and high dose groups of Chinese medicine and donepezil group was shortened， and the platform residence time was prolonged. Neuronal karyopyknosis， Nissl body dissolution and microglia activation in hippocampus were improved. Fluorescence Aβ was metabolized faster by cerebrospinal fluid. The expression of BDNF and NT-3 in hippocampus was increased （P<0.01）， and the expression of TLR4， MyD88 and p-NF-κB p65 was significantly decreased （P<0.05， P<0.01）. The expression of TNF-α in the hippocampus of the high-dose group was significantly decreased （P<0.05）， and the expression of IL-10 was significantly increased （P<0.05）. The expression of TNF-α， IL-6 and IL-1β in the hippocampus of the donepezil group was significantly decreased （P<0.05， P<0.01）. ConclusionShenxiong Huanglian Jiedu decoction may mitigate neuronal damage and enhance cerebrospinal fluid flow in the mouse model of AD， thereby promoting the clearance of Aβ and improving the learning and memory abilities. These beneficial effects are likely mediated through the inhibition of microglial activation， reduction of inflammation， and modulation of the TLR4/MyD88/NF-κB signaling pathway.

Objective:To investigate the clinical effectiveness of autologous hamstring tendon reconstruction with preserved synovial sheath combined with remnant suture in the treatment of anterior cruciate ligament (ACL) tears.Methods:A retrospective study was conducted to analyze the clinical data of 38 patients with ACL tear who had been admitted to Department of Sports Medicine, The Fourth Hospital of Wuhan from January 2016 to July 2020. There were 30 males and 8 females, with an age of (25.4±7.2) years. By the typing of MRI Sherman tear locations (MSTL) for anterior cruciate ligament, 7 cases were Type I and 31 cases type II. A total of 18 patients underwent single bundle reconstruction of autologous hamstring tendon combined with remnant suture (group A), and the other 20 patients underwent conventional reconstruction to clean the synovial sheath of ACL (group B). The operation time,Tenger scores, Lysholm scores, International Knee Documentation Committee (IKDC) subjective score and side-to-side differences in relaxation at pre- operation, 1 year and 2 years after operation, as well as ACL healing of the affected knee at 2 years after operation, were observed and compared between the 2 groups. The graft synovial coverage was evaluated by secondary arthroscopy in some cases.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (38.5±8.4) months. No surgical site infection or knee stiffness occurred in the 2 groups after operation, and 2 patients in each group developed intermuscular venous thrombosis at a lower limb. There was no significant difference in operation time between the 2 groups ( P>0.05). There were significant differences in Tenger score [(6.3±1.6) points versus (4.7±1.7) points], Lysholm score [(93.4±4.2) points versus (85.9±4.3) points] and IKDC subjective score [(89.1±2.9) points versus (81.2±2.9) points] between group A and group B at 1 year after operation ( P<0.05), but there was no significant difference in Tenger score, Lysholm score or IKDC subjective score between the 2 groups at 2 years after operation ( P>0.05). There was no significant difference in side-to-side difference in relaxation between the 2 groups at 1 year or 2 years after operation ( P>0.05). MRI evaluation at 2 years after operation showed no recurrent rupture or no sign of impingement between the graft and the intercondylar fossa in either group. Conventional secondary arthroscopy for 2 patients in group A and 3 patients in group B revealed better synovial coverage in group A. Conclusion:In the treatment of ACL tears of MSTL types I and II, compared with conventional reconstruction to clean the synovial sheath of ACL, autologous hamstring tendon reconstruction with preserved synovial sheath combined with remnant suture can lead to better functional recovery at 1 year after operation, though there is no significant difference in function at 2 years after operation.

OBJECTIVE: To summarize the methods of ankle hinge position design in the correction of clubfoot deformity by Ilizarov method, and to explore its application value in the prevention of ankle dislocation. METHODS: A retrospective study was conducted including 28 patients with rigid clubfoot deformity (34 feet) who met the selection criteria and admitted between September 2021 and December 2024. There were 19 males and 9 females with an average age of 31.8 years (range, 19-47 years). According to Dimeglio classification, there were 21 feet of degree Ⅲ and 13 feet of degree Ⅳ. The causes were traumatic sequelae in 9 cases, congenital foot deformity in 15 cases, spina bifida sequelae in 1 case, peripheral neuropathy in 1 case, and cerebral palsy sequelae in 2 cases. The malformation lasted from 6 to 46 years, with an average of 29.3 years. All patients were treated with Ilizarov circular external fixator, and the hinge position of ankle joint was planned according to the standard lateral X-ray film of foot and ankle and the principle of Ilizarov limb deformity correction center of rotation angulation (CORA) before operation. The 2008 International Clubfoot Study Group (ICFSG) scoring system was used to evaluate the efficacy. RESULTS: The deformity of rigid clubfoot was completely corrected in all patients, and the patients could walk with plantar weight-bearing, and the ankle weight-bearing walking significantly improved when compared with that before operation. There was no complication such as ankle dislocation, talus impact or extrusion, local skin necrosis, needle tract infection, or numbness of extremities during the correction process. All patients were followed up 5-39 months, with an average of 18.1 months. At last follow-up, according to the ICFSG scoring system, 23 feet were excellent, 10 feet were good, and 1 foot was fair, and the excellent and good rate was 97%. CONCLUSION Designing the position of the ankle hinge according to the principle of CORA can effectively avoid ankle dislocation, talus impingement, tibiotalar joint extrusion, and other ankle adverse events in the process of correcting clubfoot deformity, which has good application value in clinical practice.

Objective:To investigate the efficacy of robot-assisted femoral tunnel localization in reconstruction of the medial patellofemoral ligament (MPFL).Methods:A retrospective study was conducted to analyze the 36 patients who had been admitted to Department of Sports Medicine, The Fourth Hospital of Wuhan between January 2019 and January 2022 due to recurrent patellar dislocation. There were 15 males and 21 females; age: 23.5 (18.3, 29.0) years; number of dislocations: 2.5 (2.0, 3.0). They were stratified into 2 cohorts based on utilization of robot-assistance. In the observation group (17 cases), the femoral tunnel localization was robot-assisted in MPFL reconstruction; in the control group (19 cases), the femoral tunnel localization was guided by C-arm fluoroscopy in MPFL reconstruction. The 2 groups were compared in terms of operation time, frequency of guide wire placement, visual analogue scale (VAS) at postoperative 1 d, patellar tilt angle (PTA) and the disparity between actual femoral tunnel insertion and ideal tunnel insertion point (Sch?ttle point) at postoperative 1 to 3 d, and Lysholm knee score and International Knee Documentation Committee (IKDC) score at the last follow-up.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). All patients were followed up for 12.0 (10.3, 13.0) months. In the observation group, the operation time [(64.1±16.7) min], frequency of guide wire placement [1.0 (1.0, 2.0) times], VAS [2.5 (2.0, 3.0) points], and disparity between actual femoral tunnel insertion and ideal tunnel insertion point [(4.7±1.2) mm] were significantly better than those in the control group [(84.2±19.7) min, 3.0 (2.0, 4.0) times, 3.5 (3.0, 4.0) points, and (6.1±1.2) mm] ( P<0.05). There was no statistical difference between the 2 groups in PTA, Lysholm knee score or IKDC score ( P>0.05). Conclusions:The short-term clinical efficacy of robot-assisted femoral tunnel localization is satisfactory in MPFL reconstruction. Compared with the intraoperative C-arm fluoroscopy, robot-assisted localization can decrease the frequency of guide wire placement, enhance femoral tunnel accuracy and efficiency, and alleviate more postoperative pain for the patients.

OBJECTIVE: To explore the effect of chitosan (CS) hydrogel loaded with tendon-derived stem cells (TDSCs; hereinafter referred to as TDSCs/CS hydrogel) on tendon-to-bone healing after rotator cuff repair in rabbits. METHODS: TDSCs were isolated from the rotator cuff tissue of 3 adult New Zealand white rabbits by Henderson step-by-step enzymatic digestion method and identified by multidirectional differentiation and flow cytometry. The 3rd generation TDSCs were encapsulated in CS to construct TDSCs/CS hydrogel. The cell counting kit 8 (CCK-8) assay was used to detect the proliferation of TDSCs in the hydrogel after 1-5 days of culture in vitro, and cell compatibility of TDSCs/CS hydrogel was evaluated by using TDSCs alone as control. Another 36 adult New Zealand white rabbits were randomly divided into 3 groups ( n=12): rotator cuff repair group (control group), rotator cuff repair+CS hydrogel injection group (CS group), and rotator cuff repair+TDSCs/CS hydrogel injection group (TDSCs/CS group). After establishing the rotator cuff repair models, the corresponding hydrogel was injected into the tendon-to-bone interface in the CS group and TDSCs/CS group, and no other treatment was performed in the control group. The general condition of the animals was observed after operation. At 4 and 8 weeks, real-time quantitative PCR (qPCR) was used to detect the relative expressions of tendon forming related genes (tenomodulin, scleraxis), chondrogenesis related genes (aggrecan, sex determining region Y-related high mobility group-box gene 9), and osteogenesis related genes (alkaline phosphatase, Runt-related transcription factor 2) at the tendon-to-bone interface. At 8 weeks, HE and Masson staining were used to observe the histological changes, and the biomechanical test was used to evaluate the ultimate load and the failure site of the repaired rotator cuff to evaluate the tendon-to-bone healing and biomechanical properties. RESULTS: CCK-8 assay showed that the CS hydrogel could promote the proliferation of TDSCs ( P<0.05). qPCR results showed that the expressions of tendon-to-bone interface related genes were significantly higher in the TDSCs/CS group than in the CS group and control group at 4 and 8 weeks after operation ( P<0.05). Moreover, the expressions of tendon-to-bone interface related genes at 8 weeks after operation were significantly higher than those at 4 weeks after operation in the TDSCs/CS group ( P<0.05). Histological staining showed the clear cartilage tissue and dense and orderly collagen formation at the tendon-to-bone interface in the TDSCs/CS group. The results of semi-quantitative analysis showed that compared with the control group, the number of cells, the proportion of collagen fiber orientation, and the histological score in the TDSCs/CS group increased, the vascularity decreased, showing significant differences ( P<0.05); compared with the CS group, the proportion of collagen fiber orientation and the histological score in the TDSCs/CS group significantly increased ( P<0.05), while there was no significant difference in the number of cells and vascularity ( P>0.05). All samples in biomechanical testing failed at the repair site during the testing process. The ultimate load of the TDSCs/CS group was significantly higher than that of the control group ( P<0.05), but there was no significant difference compared to the CS group ( P>0.05). CONCLUSION TDSCs/CS hydrogel can induce cartilage regeneration to promote rotator cuff tendon-to-bone healing.

Objective:To observe the effect of the Yushen Yangluan decoction on ovarian reserve function in mice with diminished ovarian reserve (DOR) and to explore its mechanism of action based on the hypoxia-inducible factor (HIF)-1α/vascular endothelial growth factor A (VEGFA) signaling pathway.Methods:Mechanism analysis was conducted using artificial intelligence-based network pharmacology. Fifty 6-week-old female C57BL/6 mice were randomly divided into five groups according to body weight, with 10 mice in each group. The groups were as follows: control group, model group, low-dose Traditional Chinese Medicine (TCM) group, medium-dose TCM group, and high-dose TCM group. Hematoxylin-eosin staining was used to observe the number of antral follicles in the ovaries, enzyme-linked immunosorbent assay was employed to detect serum hormone levels, and TdT-mediated dUTP nick end labeling (TUNEL) was used to assess apoptosis in ovarian granulosa cells. Immunohistochemistry (IHC) was performed to detect ovarian expression of HIF-1α, and Western blotting was used to measure the protein expressional levels of HIF-1α, VEGFA, and B-cell lymphoma-2 (BCL2) in the ovaries.Results:After treating DOR model mice with the Yushen Yangluan decoction at low, medium, and high dosages, the ovarian antral follicle count of the mice in the TCM groups was all higher than that in the model group ( P=0.024, P<0.001, P<0.001), the follicle-simulating hormone level was lower than that in the model group ( P=0.003, P<0.001, P<0.001), and the serum anti-Müllerian hormone level in the medium-and high-dose TCM groups was higher than that in the model group ( P=0.001, P<0.001). Network pharmacology and molecular docking suggested that the formula may influence the HIF signaling pathway through core targets such as HIF-1α, BCL2 and VEGFA. TUNEL assays indicated that the apoptosis rate of ovarian granulosa cells in the low-, medium-, and high-dose TCM groups was significantly lower than that in the model group ( P=0.017, P=0.003, P<0.001). Immunohistochemistry results showed that the expression level of HIF-1α in the granulosa cells of the follicles in the low-, medium- and high-dose TCM groups was significantly higher than that in the model group ( P=0.008, P<0.001, P<0.001). Western blotting analysis indicated that the protein expression level of HIF-1α in medium-, and high-dose TCM groups was significantly higher than that in the model group ( P=0.004, P<0.001), and the protein expression levels of VEGFA and BCL2 in low-, medium-, and high-dose TCM groups were significantly higher than those in the model group ( P=0.003, P=0.002, P=0.001; P=0.029, P=0.007, P=0.001). Conclusion:The Yushen Yangluan decoction may exert its therapeutic effect by inhibiting apoptosis of ovarian granulosa cells through the HIF-1α/VEGFA signaling pathway.
