The theory of "Yang transforming Qi while Yin constituting form" in the Huangdi's Internal Classic is derived from the application， transformation， movement， and balance of Tao. It is highly condensed， revealing the true meaning of Tao and guiding the changes and progress of all natural things， including diseases. Therefore， the appearance of various physical diseases is the manifestation of Yin-Yang Qi transformation. Sweat pore， formed by the Qi transformation of Yin and Yang， is the nourishing and regulating system. It serves as the hub and channel， assisting in the flow and transformation of Qi， facilitating the exchange of material， energy， and information with the outside world. With sweat pore as the hub and based on the macro-control and holistic thinking of "Yang transforming Qi while Yin constituting form"， this paper explores the microscopic mechanisms underlying chronic liver disease. In combination with the roles of mitochondria， exosomes， and the ultraliver sieve structure in the formation and progression of chronic liver disease， this paper elucidates the close internal relationship between the disease's initial quality， symptom signs， and its physiological and pathological functions under the guidance of this theory. Modern studies have shown that autophagy， intestinal flora disorders， glucose and lipid metabolism disturbances， activation of inflammatory factors， ferroptosis， and other microscopic pathological mechanisms are involved in the occurrence and development of chronic liver disease. The common connotation of the Yin-Yang concept in traditional Chinese medicine （TCM） and the pathological mechanisms in modern medicine is deeply analyzed. The corresponding relevant microscopic mechanisms and the guiding role of the theory of "Yang transforming Qi while Yin constituting form-sweat pore" in the management of chronic liver disease are summarized. Wind medicine promotes growth and transformation through sweat pore. The combination of pungent and sweet medicines facilitates Yang and disperse Yin. The formulas， combining the characteristics of wind medicine and pungent and sweet medicines， fit the principle of "Yang transforming Qi while Yin constituting form-sweat pore". This paper combines both macro and micro perspectives to explain the scientific connotation and microscopic mechanisms of chronic liver disease based on the theory of "Yang transforming Qi while Yin constituting form-sweat pore"， and explore the prevention and treatment of chronic liver disease through the principles， methods， prescriptions， and medicines featured by combination of pungent and sweet medicines， facilitating Yang， activating sweat pore， and dispersing Yin， providing new ideas and reference for the clinical treatment of chronic liver disease.

Objective To analyze the efficacy of modified transvaginal rectal repair(MTVRR)in patients with moderate to severe rectocele(RC).Methods A retrospective analysis was conducted on the clinical data of 21 female patients with RC who underwent MTVRR.The Constipation Scoring System(CSS)scale was used to assess patients'constipation symptoms before surgery and at 3,6,12 and 24 months after surgery,and the efficiency of symptom improvement was recorded.The occurrence of postoperative complications in RC patients was observed.Results All 21 patients successfully un-derwent the surgery,with surgical duration ranging from 25 to 135 minutes,with average of(83.14±30.39)minutes,and hospital stay ranging from 10 to 21 days,with average of(14.10±2.34)days.Postoperatively,one patient was lost during follow-up among 21 patients.The CSS scores of the remai-ning 20 patients were lower than those before surgery,with a statistically significant difference(P＜0.05).The overall effective rates of constipation symptom improvement at 3,6 and 12 months postop-eratively were 100.00％,90.00％and 80.00％,respectively.Among 20 patients,15 patients com-pleted 24-month follow-up after surgery,and the CSS score after surgery was lower than that before sur-gery,the difference was statistically significant(P＜0.05).The CSS scores of the remaining 15 pa-tients were lower than those before surgery,with a statistically significant difference(P＜0.05).The overall effective rate of constipation symptom improvement at 24 months postoperatively was 80.00％among 15 patients.During postoperative follow-up,it revealed that no complications occurred in any patient.Conclusion MTVRR can improve constipation symptoms in patients with RC,demonstra-ting good therapeutic efficacy.

ObjectiveTo observe the effects of Tongmai Kaiqiao pills on the hypoxia-inducible factor-1α （HIF-1α）/adenovirus E1B 19 kD-interacting protein 3 （BNIP3） signaling pathway and mitochondrial autophagy in the hippocampus of the rat model of vascular dementia （VD）. MethodNinety male SD rats underwent adaptive feeding for one week before the study. Ten rats were randomly assigned to the sham group， where the common carotid artery was isolated without ligation. The remaining rats were subjected to sequential ligation of the common carotid artery for the modeling of VD. The successfully modeled rats were randomly assigned into the following groups： model， high-， medium-， and low-dose （27.6， 13.8， 6.9 g·kg^-1， respectively） Tongmai Kaiqiao pills， donepezil hydrochloride （0.45 mg·kg^-1）， and combination （27.6 g·kg^-1 Tongmai Kaiqiao pills + 2.5 mg·kg^-1 HIF-1α inhibitor YC-1） groups. After 4 weeks of treatment， samples were collected. Nissl staining and hematoxylin-eosin staining were performed to observe the loss of neurons and pathological changes， respectively， in the hippocampal region. Western blot was employed to determine the protein levels of HIF-1α， BNIP3， Beclin-1， and microtubule-associated protein 1 light chain 3B （LC3B） in the hippocampal tissue. Transmission electron microscopy was used to observe the mitochondrial ultrastructure and the number of autophagosomes in the hippocampal tissue. Immunofluorescence was employed to observe the fluorescence intensity of HIF-1α， BNIP3， and LC3B in the hippocampal tissue. ResultCompared with the sham group， the model group showed prolonged escape latency （P<0.01）， decreased number of platform crossings （P<0.01）， reduced and disarranged neuronal layers in the hippocampal region， decreased number of Nissl bodies， disrupted mitochondrial cristae， damaged mitochondrial double-membrane structures， increased number of autophagosomes， upregulated expression of HIF-1α， BNIP3， beclin1， and LC3B （P<0.05， P<0.01）， and enhanced fluorescence intensity of HIF-1α， BNIP3， and LC3B （P<0.05， P<0.01）. Compared with the model group， Tongmai Kaiqiao pills and donepezil hydrochloride shortened the searching time for the platform （P<0.01） and increased the number of platform crossings （P<0.01）. Moreover， the drugs increased the number of neurons with normal morphology and orderly arrangement and the number of Nissl bodies， alleviated the damage， increased the number of autophagosomes， upregulated the expression of HIF-1α， BNIP3， Beclin1， and LC3B （P<0.05， P<0.01）， and enhanced the fluorescence intensity of HIF-1α， BNIP3， and LC3B （P<0.05， P<0.01）. Compared with high-dose Tongmai Kaiqiao pills， the combination group prolonged the escape latency （P<0.01）， reduced the number of crossing platforms （P<0.01）， decreased the number of hippocampal neurons， aggravated the damage， decreased the number of Nissl bodies and autophagosomes， downregulated the expression of HIF-1α， BNIP3， beclin1， and LC3B （P<0.01）， and decreased the fluorescence intensity of HIF-1α， BNIP3， and LC3B （P<0.01）. ConclusionTongmai Kaiqiao pills may activate the HIF-1α/BNIP3 signaling pathway to promote the occurrence of mitochondrial autophagy， clear damaged mitochondria， provide energy for healthy cells， reduce neuronal cell death， and restore the brain function， thereby reducing ischemic damage to the hippocampal tissue， improving learning and memory abilities， and exerting therapeutic effects on VD in rats.

High glucose level, bacterial infection, and persistent inflammation within the microenvironment are key factors contributing to the delay of diabetic ulcers healing, while traditional therapeutic methods generally fail to address these issues simultaneously. Here, we present a spatiotemporally responsive cascade bilayer microneedle (MN) patch for accelerating diabetic wound healing via local glucose depletion and sustained nitric oxide (NO) release for long-term antibacterial and anti-inflammatory effects. The MN patch (G/AZ-MNs) possesses a degradable tip layer loading glucose oxidase (GOx), as well as a dissolvable base layer encapsulating l-arginine (Arg)-loaded nanoparticles (NPs). After wound administration, the base part rapidly dissolved, resulting in prompt separation of the MN tip within the wound tissue, which subsequently responded to the overexpressed matrix metalloproteinase-9 (MMP-9) in diabetic lesions, leading to the responsive release of GOx. The released enzyme catalyzed glucose into gluconic acid and hydrogen peroxide (H₂O₂), which not only reduced glucose level within the diabetic wound, but also initiated the cascade reaction between H₂O₂ with the Arg that was released from NPs, thereby achieving continuous production of NO for 7 days. Our findings demonstrate that a single administration of the MN patch could effectively heal non-infected or biofilm-infected diabetic wounds with the multifunctional properties.

Hepatic fibrosis is a common complication of chronic liver disease， seriously affecting patients' quality of life and leading to severe consequences such as cirrhosis and liver cancer. Modern medicine has made progress in the treatment of hepatic fibrosis， while it still faces certain challenges and limitations. Therefore， seeking new therapeutic strategies is of great clinical significance. The nuclear factor-κB （NF-κB） signaling pathway plays a role in regulating inflammation and immune responses. Recent studies have shown that the NF-κB signaling pathway plays a key role in the occurrence and development of hepatic fibrosis. The abnormal activation of the NF-κB signaling pathway leads to the overexpression of genes related to liver inflammation and fibrosis， thereby promoting the development of hepatic fibrosis. Traditional Chinese medicine （TCM） is a traditional treatment method with unique advantages and potential. In recent years， increasing studies have proved that TCM can treat hepatic fibrosis by regulating the NF-κB signaling pathway. The active ingredients in Chinese herbal medicines can intervene in the activation of the NF-κB signaling pathway to inhibit inflammatory responses， thereby reducing the severity of hepatic fibrosis. This article reviews the mechanisms of TCM in treating hepatic fibrosis via the NF-κB signaling pathway and evaluates the efficacy and discusses the clinical application prospects of relevant Chinese herbs and formulae， aiming to provide references for further research and clinical practice.
