[Professor MA Kun treats infertility caused by uterine dysplasia with kidney deficiency and blood stasis].

Uterine dysplasia is a common cause of infertility. Traditional Chinese medicine has unique advantages in the treatment of this disease. This paper introduces a case of infertility caused by uterine dysplasia treated by Professor MA Kun who adopted the therapy of tonifying kidney and activating blood, aiming to summarize the theoretical foundation and formula principles of Professor MA Kun in the clinical treatment of this disease. The kidney stores essence and governs reproduction. Kidney deficiency is the root cause of infertility. The deficiencies in kidney Qi, Yin, and Yang can result in blood stasis to obstruct the uterus, leading to insufficient source for essence and aggravating kidney deficiency. Kidney deficiency and blood stasis affect each other and form a vicious cycle, resulting in uterine dysplasia due to insufficient nutrition and difficult pregnancy. Therefore, Professor MA Kun believes that kidney deficiency and blood stasis is the key pathogenesis of infertility caused by uterine dysplasia and proposes the treatment principle of tonifying kidney and activating blood. Sufficient essence and Qi in the kidney can resolve stasis and generate blood, thus harmonizing Yin and Yang, which can reach thoroughfare and conception vessels to nourish the uterus and recover the normal physiological function of the uterus. In that case, normal pregnancy is possible. Professor MA Kun attaches importance to the therapeutic principle of supplementing Qi and nourishing blood. In addition, she advocates conforming to changes in the menstrual cycle to promote the development of the uterus and the implantation of fertilized eggs. She also integrates traditional Chinese medicine and western medicine to treat both symptoms and root causes. Professor MA Kun's experience has demonstrated definite clinical effect on this disease and can be taken as a reference.

[Examples of Professor MA Kun's treatment of infertility caused by uterine fibroids using method of tonifying kidney and activating blood].

Uterine fibroids are a prevalent factor that impacts fertility in women of reproductive age. This study discusses the theoretical foundation and formula principles of Professor MA Kun's clinical treatment for infertility caused by uterine fibroids. The kidney stores essence and is responsible for reproduction, while blood serves as a vital material basis for women's physiological functions. Kidney deficiency is the fundamental pathogenesis of infertility, and imbalances in kidney Qi and essence or deficiencies in kidney Yin and Yang can result in blood stasis. Blood stasis plays a significant role throughout this condition by impeding the flow of blood, which is crucial for nourishing Qi. Therefore, both kidney deficiency and blood stasis are key factors contributing to infertility caused by uterine fibroids. Professor MA Kun treats infertility caused by uterine fibroids using an approach that involves tonifying the kidneys and activating blood circulation based on changes in Qi and blood during the menstrual cycle as well as follicular growth processes. By identifying stage-specific evidence, appropriate treatments can be applied accordingly. During menstruation when the uterus opens and menstrual blood flows out, promoting follicular development through nourishing kidney Yin and activating blood circulation becomes essential. In later stages of menstruation, additional measures are taken to remove blood stasis, alleviate symptoms, disperse knots, attack pathogens while simultaneously replenishing vital energy. During intermenstrual periods when Yin holds greater importance than Yang, tonifying the kidneys and activating blood circulation helps facilitate smooth discharge of eggs by promoting transformation between Yin and Yang energies. Premenstrual period to warm kidney Yang to promote pregnant egg implantation, and at the same time to dredge the liver and regulate Qi, Qi elimination stagnation, complementary in the line, with the symptoms of additional subtractions. Clinical effect is remarkable, for the reference of colleagues.

Treatment of diabetic retinopathy with herbs for tonifying kidney and activating blood circulation: A review of pharmacological studies.

ETHNOPHARMACOLOGICAL RELEVANCE: Diabetic retinopathy (DR) is a prevalent microvascular complication of diabetes. Chinese medicine believes that kidney deficiency and blood stasis are significant pathogenesis of DR. A characteristic therapeutic approach for this pathogenesis is the kidney-tonifying and blood-activating method. By literature retrieval from several databases, we methodically summarized the commonly used kidney-tonifying and blood-activating herbs for treating DR, including Lycii Fructus, Rehmanniane Radix Praeparata, and Corni Fructus with the function of nourishing kidney; Salvia Miltiorrhizae Radix et Rhizoma with the function of enhancing blood circulation; Rehmanniae Radix with the function of nourishing kidney yin; and Astragali Radix with the function of tonifying qi. It has been demonstrated that these Chinese herbs described above, by tonifying the kidney and activating blood circulation, significantly improve the course of DR. AIM OF THE STUDY: Through literature research, to gain a thorough comprehension of the pathogenesis of DR. Simultaneously, through the traditional application analysis, modern pharmacology research and network pharmacology analysis of kidney-tonifying and blood-activating herbs, to review the effectiveness and advantages of kidney-tonifying and blood-activating herbs in treating DR comprehensively. MATERIALS AND METHODS: PubMed, the China National Knowledge Infrastructure (CNKI), and Wanfang Data were used to filter the most popular herbs for tonifying kidney and activating blood in the treatment of DR. The search terms were "diabetic retinopathy" and "tonifying kidney and activating blood". Mostly from 2000 to 2023. Network pharmacology was applied to examine the key active components and forecast the mechanisms of kidney-tonifying and blood-activating herbs in the treatment of DR. RESULTS: Kidney deficiency and blood stasis are the pathogenesis of DR, and the pathogenesis is linked to oxidative stress, inflammation, hypoxia, and hyperglycemia. Scientific data and network pharmacology analysis have demonstrated the benefit of tonifying kidney and activating blood herbs in treating DR through several channels, multiple components, and multiple targets. CONCLUSIONS: This review first presents useful information for subsequent research into the material foundation and pharmacodynamics of herbs for tonifying kidney and activating blood, and offers fresh insights into the treatment of DR.

Effect of vessel number on computational fluid dynamics in vascular networks / 中国组织工程研究

BACKGROUND:Mechanical factors can affect the angiogenic ability of vascular endothelial cells.How the vessel number affects the hydrodynamic properties of microvessels remains to be clarified. OBJECTIVE:To investigate the influence of vessel number on the hydrodynamics of vascular networks based on computational fluid dynamics. METHODS:Three three-dimensional models of vascular network with different vessel numbers were constructed using the Geometry module of ANSYS 19.0 software,and then the vascular network was meshed to tetrahedral elements in Mesh module.The vascular network was assumed to rigid wall without slip,and the blood was assumed to laminar,viscous,and incompressible Newtonian fluid.Blood density,velocity,and a series of blood viscosity coefficients were also established.The Navier-Stokes equation was used for calculation.Hydrodynamic properties of different parts of vascular network with different vessel numbers were analyzed and compared. RESULTS AND CONCLUSION:The streamline,velocity,and mass flow all had the same trend in the vascular network,that is,the outlet and inlet were higher and the middle junction of vascular network was lower.The more the number of vessels,the thinner the blood flow lines in each part of the vascular network.Also,the velocity,mass flow,and wall shear decreased with the increase of the number of blood vessels.Therefore,the changes in vessel number could influence the hydrodynamic environment in the vascular network.Computational fluid dynamics indicates that the changes in vessel numbers can influence the hydrodynamic properties of blood,and provides a new idea for treating bone hypoperfusion-induced diseases(fracture nonunion,bone defect,osteoporosis,etc.)through tonifying kidney and activating blood circulation based on the coupling between angiogenesis and osteogenesis.

[Mechanism of tonifying kidney and activating blood therapy for premature ovarian failure:a review].

Healthy birth and child development are the prerequisite for improving the overall quality of the population. However, premature ovarian failure(POF) threatens the reproductive health of women. The incidence of this disease has been on the rise, and it tends to occur in the young. The causes are complex, involving genetics, autoimmune, infectious and iatrogenic factors, but most of the causes remain unclear. At the moment, hormone replacement therapy and assisted reproductive technology are the main clinical approaches. According to traditional Chinese medicine(TCM), kidney deficiency and blood stasis are one of the major causes of POF, and TCM with the effects of tonifying kidney and activating blood has a definite effect. Through clinical trials, TCM prescriptions for POF have excellent therapeutic effect as a result of multi-target regulation and slight toxicity. In particular, they have no obvious side effects. A large number of studies have shown that the kidney-tonifying and blood-activating TCM can regulate the neuroendocrine function of hypothalamic-pituitary-ovarian axis, improve ovarian hemodynamics and microcirculation, reduce the apoptosis of granulosa cells, alleviate oxidative stress injury, and modulate immunologic balance. The mechanism is that it regulates the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), vascular endothelial growth factor(VEGF), transforming growth factor(TGF)-ß/Smads, nuclear factor E2-related factor 2(Nrf2)/antioxidant response element(ARE), and nuclear factor-kappa B(NF-κB) signaling pathways. This article summarized the pathological mechanisms of tonifying kidney and activating blood TCM in the prevention and treatment of POF and explored the biological basis of its multi-pathway and multi-target characteristics in the treatment of this disease. As a result, this study is expected to serve as a reference for the treatment of POF with the tonifying kidney and activating blood therapy.

Comparison of Therapeutic Effect of Kidney-tonifying Blood-activating Recipe and Aescuven Forte Tablets in Treating Varicocele-induced Sperm Abnormality / 广州中医药大学学报

Objective To compare the effect of kidney-tonifying blood-activating recipe (KBR) and Aescuven Forte Tablets ( AFT) in improving the sperm quality of varicocele-induced male sterility, thus to optimize the therapeutic therapy for varicocele-induced male sterility. Methods A total of 102 varicocele-induced male sterility with abnormal sperm parameters after conservative treatment were randomized into KBR group (N=53) and AFT group ( N=49) . KBR group was given KBR plus natural vitamin E and AFT group was given AFT plus natural vitamin E, and the treatment lasted for 8 continuous weeks. Before and after treatment, the quality of seminal fluid was analyzed, sperm quantization parameters such as total number of sperm (TNS) , total number of progressive motility sperm ( TNPS) , total number of normal form sperm ( TNNS) and total number of nor mal form and progressive motility sperm ( TNNPS) were observed, and the improvement rate of sperm quantization parameter was compared. Results (1) Before treatment, the differences of TNS, TNPS, TNNS and TNNPS were insignificant between the two groups ( P>0.05) . After treatment, TNNS was not improved in AFT group ( P>0.05) , but TNS, TNPS, TNNPS were much improved in both groups ( P<0.01 compared with those before treatment) . The improvement of KBR group was superior to that of AFT group ( P<0.05) . ( 2) The improvement rate for TNS, TNPS, TNNS, TNNPS was 90.57%, 79.25%, 67.92%, 77.36%in KBR group, and was 75.51%, 73.47%, 28.57%, 61.22% in AFT group respectively. The improvement rate for TNS and TNNS in KBR group was superior to that in AFT group ( P<0.05 or P<0.01) . Conclusion Varicocele-induced male sterility patients usually have the syndrome of kidney deficiency and blood stasis, so KBR, which has the function of tonifying kidney and activating blood, has synergistic action on the effect of AFT in improving sperm quality of varicocele-induced male sterility patients.
