Patients with panvascular disease （PVD） often experience bleeding events while receiving standard antithrombotic therapy. Based on the theory of "guarding the channel passages"， the retention of blood stasis is considered as a crucial pathological basis for PVD. The combination of the retention of blood stasis and the failure of the channel passages to contain blood constitutes the core pathogenesis of bleeding events in this condition. According to their pathogenesis and clinical characteristics， bleeding events in PVD are categorized into a bleeding stage and a stable stage. During the bleeding stage， treatment should focus on stanching bleeding and dispersing stasis to restore normal circulation in the channel passages. During the stable stage， treatment should aim to dispel stasis and generate new blood to harmonize the channel passages. In clinical practice， physicians should dynamically weigh the risks of bleeding and ischemia against the intensity of antithrombotic therapy. The ultimate goal is to harmonize qi and blood and ensure that blood remains properly contained within the channel passages， thereby reducing the risk of bleeding events and enhancing overall patient benefit.

This article explores the pathogenesis ， evolution and the prevention-treatment strategies of hypertension-related coronary microvascular dysfunction （H-CMD） from the collateral disease theory. Long-term hypertension may lead to coronary microvascular vasomotor imbalance， endothelial injury， vascular remodeling， microthrombosis， reduced perfusion reserve， and microvascular rarefaction， suggesting a progressive pathological process from functional disturbance to structural injury， collateral obstruction， and insufficient repair. Collateral disease theory emphasizes the network-like distribution， gradual branching， and permeating and nourishing functions of collaterals， as well as the concept that prolonged disease enters the collaterals， providing a reference for understanding coronary microcirculatory dysfunction and malnourishment of heart collaterals. Accordingly， the traditional Chinese medicine （TCM） pathogenesis of H-CMD can be summarized into four interconnected stages： Collateral Qi stagnation， scorching injury of collateral vessels， phlegm-stasis obstruction of collaterals， and collateral deficiency with malnourishment. Collateral Qi stagnation is the initiating stage， mainly corresponding to abnormal coronary microvascular vasomotor regulation and endothelial dysfunction. Scorching injury of collateral vessels represents the developmental stage and is closely associated with inflammation， oxidative stress， and endothelial barrier injury after Qi stagnation transforms into fire. Phlegm-stasis obstruction of collaterals represents the prolonged stage and may aggravate vascular wall thickening， luminal stenosis， microthrombosis， and insufficient microcirculatory perfusion. Collateral deficiency with malnourishment is the late-stage outcome， reflecting deficiency of healthy Qi， collateral damage， Qi-blood malnourishment， and weakened repair capacity， mainly manifested as microvascular rarefaction， occlusion， and microcirculatory homeostatic imbalance. Therapeutically， stage-based syndrome differentiation and the combined strategy of dredging and nourishing collaterals should be emphasized. Specifically， promoting Qi movement， resolving stagnation， soothing the liver， and harmonizing collaterals should be adopted in the early stage. Clearing heat， pacifying the liver， calming and protecting collaterals should be adopted in the developmental stage. Resolving phlegm， activating blood， and dredging collaterals should be implemented in the prolonged stage. Supplementing Qi， nourishing blood， tonifying the kidney， regulating balance， strengthening healthy Qi， and nourishing collaterals should be carried out in the late stage. Related formulas and medicinals may act by regulating the nitric oxide/endothelin-1（NO/ET-1） balance， inhibiting inflammation and oxidative stress， improving microcirculatory perfusion， and promoting angiogenesis and endothelial repair. Collateral disease theory may provide a theoretical basis for understanding the dynamic pathogenesis of H-CMD and for stage-based TCM intervention.

Objective:To evaluate the impact of donor characteristics on the prognosis of myelodysplastic syndrome (MDS) patients undergoing haplo-identical transplantation (HIDT) .Methods:A retrospective analysis of 203 MDS patients who received HIDT was conducted to evaluate how donor factors influenced transplant outcomes.Results:In MDS patients undergoing haploidentical transplantation, donors over 50 years were associated with higher EBV reactivation (2-year cumulative incidence 42.9% vs 22.0% for <50 years old; P=0.010). Female donors were linked to increased severe chronic GVHD compared with male donors (2-year incidence 11.9% vs 4.0% ; P=0.017). Additionally, 2-year overall survival (OS) was slightly lower with female donors than male donors (56.6% vs 69.7% ), but the difference was not statistically significant ( P=0.073). Donor-recipient blood type did not affect post-transplant OS or cumulative relapse rates. Donor-recipient kinship analysis revealed that child donors, compared to haploidentical sibling or parent donors, had lower rates of grade Ⅱ–Ⅳ acute GVHD (27.2% vs 45.7% vs 53.5%, P=0.007) and 2-year EBV reactivation (13.9% vs 29.3% vs 38.9%, P=0.001). For donors under 20 years, donor gender did not significantly affect 2-year OS ( P=0.913), relapse-free survival ( P=0.716), or 100-day incidence of grade Ⅱ–Ⅳ acute GVHD ( P=0.359) . Conclusion:For MDS patients undergoing HIDT, donors over 50 should be avoided. Male and child donors are preferred, while donor gender does not significantly affect outcomes if the donor is under 20 years old.

BACKGROUND:Ankle fracture complicated with deltoid ligament injury is clinically common,and one stage repair of deltoid ligament with internal fracture fixation has gradually become a main therapeutic method,which can significantly reduce the long-term complications of ankle joint.In recent years,new progress has been made in anatomical structure characteristics and dynamic biomechanical research of deltoid ligament,thus greatly improving repairing techniques for injury in the deep layer of deltoid ligament,but there are still some controversies.OBJECTIVE:To explore the clinical efficacy of suture anchor and medial malleolus repair in the treatment of ankle joint fractures with the deep layer of deltoid ligament.METHODS:A total of 56 patients with ankle joint fractures and complete fracture of the deep and superficial layer of deltoid ligament treated in Affiliated Haikou Hospital,Xiangya School of Medicine,Central South University from January 2017 to January 2022 were selected,and they were divided into two groups according to different treatment methods in repairing the deep layer of deltoid ligament with suture anchor:suture anchor repair group(n=32)and medial malleolus repair group(n=24).The medial clear space of ankle joint and American Orthopedic Foot and Ankle Society Score of patients in the two groups were evaluated before and after operative treatment.RESULTS AND CONCLUSION:(1)All the 56 patients finished the surgery smoothly and were followed up for more than 12 months after operation.Their ankle fracture healed,and the time for fracture healing was 8-12 weeks,with a mean of 10.5 weeks.(2)The medial clear space of ankle joint in the two groups 12 months after operation was remarkably narrower than that before operation,and the difference was statistically significant(P＜0.001).The medial clear space of ankle joint in the two groups maintained a normal range 12 months after operation,and there was no statistically significant difference between the two groups(P＞0.05).(3)The AOFAS scale of patients in the two groups 6 and 12 months after operation was obviously bigger than that before operation(P＜0.001),but there was no statistically significant difference in the American Orthopedic Foot and Ankle Society Score of patients between the two groups at corresponding time points(P＞0.05).(4)It is concluded that both suture anchor and medial malleolus repair in the treatment of injury in the deep layer of deltoid ligament can recover the medial clear space of ankle joint,effectively keep the stability of ankle,and thus achieve good clinical efficacy.

ObjectiveTo evaluate the efficacy of Shexiang Baoxinwan in treating stable angina pectoris with Qi stagnation and blood stasis syndrome in patients with coronary artery disease （CAD） complicated with anxiety and depression and explore its underlying mechanisms. MethodsThis study employed a randomized， double-blind， and placebo-controlled clinical trial design. Patients admitted to the hospital were randomly assigned to the observation group and the control group， with 52 patients in each group. Patients in the observation and control groups received Shexiang Baoxinwan and placebo， respectively， both in combination with conventional Western medication. The dose was 45.0 mg， three times daily， for a total duration of eight weeks. The primary outcome was the Seattle Angina Questionnaire （SAQ） scores before and after treatment. Secondary outcomes included changes in traditional Chinese medicine （TCM） syndrome score， the patient health questionnaire-9 （PHQ-9）， generalized anxiety disorder-7 （GAD-7）， inflammatory markers ［interleukin-18 （IL-18）， interleukin-10 （IL-10）， tumor necrosis factor-alpha （TNF-α）， CD40， etc.］， monoamine neurotransmitters ［e.g.， dopamine （DA）］， vascular endothelial function markers ［e.g.， endothelin-1（ET-1）］， adipokines， and ischemia-modified albumin （IMA）. Adverse reactions were also recorded. ResultsA total of 92 patients completed the study， with 44 in the observation group and 48 in the control group. Compared with baseline， both groups showed significant decreases in PHQ-9， GAD-7， and TCM syndrome scores following treatment （P<0.05）， along with a significant increase in SAQ scores （P<0.05）. In the observation group， DA levels were significantly increased （P<0.05）， while levels of IL-18， TNF-α， CD40， ET-1， and IMA were decreased （P<0.05）. In contrast， the control group exhibited significantly increased CD40 levels （P<0.05）. Compared with the control group after treatment， the observation group showed significant improvements in the SAQ dimensions of physical limitation， angina stability， treatment satisfaction， and disease perception， as well as in TCM syndrome score， PHQ-9 score， IL-18， CD40， ET-1， and IMA （P<0.05）. No adverse reactions were observed in either group during treatment. ConclusionShexiang Baoxinwan can improve anxiety and depression， alleviate angina symptoms， and reduce TCM symptoms of Qi stagnation and blood stasis in CAD patients. The mechanism may involve anti-inflammation， improvement of vascular endothelial function， reduction of IMA， and increase of monoamine neurotransmitter levels.
