Retinal microcirculatory disorder is a key factor in the occurrence and development of diabetic retinopathy （DR）， and also an important link in the prevention and treatment of DR. The theory of "Gaozhuo" holds that the microcirculatory disorder in DR is based on the deficiency of spleen Qi and is characterized by the obstruction caused by "Gaozhuo" and blood stasis. The deficiency of spleen Qi is an essential precondition for the endogenous formation and accumulation of Gaozhuo， while Gaozhuo invasion is the direct cause of microcirculatory disorders in DR. The deficiency of spleen Qi and the endogenous formation of Gaozhuo mean the process in which glucose metabolism dysfunction induces an excessive production of inflammatory factors and lipid metabolites. The obstruction caused by "Gaozhuo" and blood stasis is the direct pathogenesis of microcirculatory disorders in DR， encompassing two stages： Gaozhuo obstruction and turbidity and stasis stagnation. Gaozhuo obstruction and turbidity and stasis stagnation represent the process in which inflammatory factors and lipid metabolites damage the retinal microcirculation and induce thrombosis， thus mediating microcirculatory disorders. Turbidity and stasis stagnation and blood extravasation outside the vessels reveal the progression to microvascular rupture and hemorrhage resulting from the microcirculatory disorders. According to the pathogenesis evolution of the theory of "Gaozhuo"， microcirculatory disorders in DR can be divided into deficiency of spleen Qi with Gaozhuo obstruction， deficiency of spleen Qi with turbidity and stasis stagnation， and turbidity and stasis stagnation with blood extravasation outside the vessels. Clinically， treatment principles should focus on strengthening the spleen and benefiting Qi， resolving turbidity， and dispersing stasis. Different syndrome patterns should be addressed with tailored therapies， such as enhancing the spleen and benefiting Qi while regulating Qi and reducing turbidity， strengthening the spleen and benefiting Qi while resolving turbidity and dispelling stasis， and strengthening the spleen and resolving turbidity while removing stasis and stopping bleeding.

ObjectiveTo investigate the differential expression of integrin alpha-6（ITGA6） in abdominal wall endometriosis （AWE） tissues and its molecular mechanisms in regulating AWE. Methods36 AWE lesions were designated as the experimental group， while 36 cases of normal endometrial tissues served as the controls. Differential expression of ITGA6 between the two groups was assessed through immunohistochemical （IHC） staining. Human ITGA6 gene-specific interference sequences were designed， synthesized， and packaged into lentiviral vectors to establish the Ishikawa cell line with ITGA6-knockdown. Similarly， the ITGA6-overexpression cell line was constructed using the coding sequence （CDS） of the gene. Real-time PCR and Western blot were performed to detect changes in epithelial-mesenchymal transition（EMT）-related markers and angiogenesis-related indicators. Cell invasion and migration capabilities were assessed by Cell Scratch and Transwell assays. Furthermore， Western blot was conducted to profile PI3K/AKT pathway dynamics. ResultsEctopic endometrial tissues exhibited a marked increase in the number of ITGA6-positive cells and their expression intensity compared to eutopic endometrium （each P < 0.001）. Compared with the NC group， the ITGA6-knockdown group showed significantly reduced expression of N-cadherin， VEGF， and TGF-β1 （all P < 0.01）， while E-cadherin expression was markedly increased （P < 0.01）. Concomitantly， the invasion and migration capacities of ITGA6-low expression were significantly impaired （P < 0.001 for both）， accompanied by a marked reduction in AKT and phosphorylated AKT（p-AKT） levels （P < 0.001）. Conversely， overexpressing ITGA6 resulted in opposite effects. ConclusionITGA6 modulates EMT and angiogenesis in Ishikawa cells via the PI3K/AKT signaling pathway， thereby enhancing cell invasion and migration capabilities， which contributes to the pathogenesis of AWE.

Dry eye disease(DED)is a common ocular surface disorder worldwide, primarily characterized by a loss of homeostasis of the tear film, and frequently associated with meibomian gland dysfunction(MGD), decreased tear film stability, ocular discomfort, and visual impairment. In recent years, factors such as the widespread use of digital devices,the aging population, and environmental changes have contributed to a significant increase in its global prevalence, making it a major public health concern. Red light therapy(RLT), also known as low-level laser therapy(LLLT)or photobiomodulation(PBM), is a non-invasive treatment that utilizes low-energy red or near-infrared light to irradiate tissues. It exerts photobiomodulatory effects to promote cellular repair and functional recovery. This therapy has demonstrated considerable potential in treating various ocular conditions. Its broader clinical application could improve therapeutic outcomes, alleviate patient discomfort and financial burden, and reduce the consumption of healthcare resources, thereby yielding significant socio-economic benefits. This paper systematically reviews the multifaceted mechanisms and application prospects of RLT in managing DED, including its anti-inflammatory effects, improvement of meibomian gland function, promotion of conjunctival goblet cell repair, and alleviation of visual fatigue, aiming to provide a theoretical foundation and practical reference for its clinical adoption.

OBJECTIVE To study the improvement effects and potential mechanisms of water extract from Chrysanthemum morifolium on skeletal muscle atrophy in rats after ischemic stroke. METHODS Sprague-Dawley rats were randomly divided into sham operation group， model group， ATP group （10 mg/kg）， C. morifolium water extract high-dose and low-dose groups （1.08， 0.54 g/kg）. Except for sham operation group， ischemic stroke models were induced in rats from the other groups using middle cerebral artery occlusion. Starting from the first day after surgery， rats in each group were given corresponding drug/normal saline intragastrically， once a day， for consecutive 7 days. On the 7th day post-surgery， the rats’ body weights were measured， and their motor functions were evaluated， including Longa scores， exercise distance， grip strength； the electrophysiological signals of the skeletal muscles in rats were measured； the pathological morphology of the soleus muscle in rats was observed； the levels of tumor necrosis factor-α （TNF-α） in serum and soleus muscle were measured； the expressions of proteins related to TNF-α/c-Jun N- terminal kinase （JNK）/mitogen-activated protein kinase （MAPK） signaling pathway in the soleus muscle were determined. RESULTS Compared with sham operation group， the body weight， grip strength and exercise distance of rats were decreased/ shortened significantly （P＜0.01）； additionally， there was a notable reduction in the interpeak value of skeletal muscle electrophysiology （P＜0.05 or P＜0.01）. Longa score， as well as the levels of TNF-α in serum and soleus muscle， and the expression levels of TNF-α， phosphorylated JNK， phosphorylated MAPK， muscle ring-finger protein-1， and muscle atrophy Fbox- 1 protein in the soleus muscle， were all significantly elevated （P＜0.01）. The skeletal muscle cells of the soleus muscle in the model group showed significant atrophy， with a markedly decreased cross-sectional area （P＜0.01）. Compared with the model group， the levels of the aforementioned indicators were significantly reversed in C. morifolium water extract groups （P＜0.05 or P＜ 0.01）， and the skeletal muscle cells of the soleus muscle were markedly enlarged. CONCLUSIONS C. morifolium water extract can improve skeletal muscle atrophy in rats after ischemic stroke， the mechanism of which may be associated with suppressing the activation of the TNF- α/JNK/MAPK E-mail：19932015@cdutcm.edu.cn signaling pathway.

The concept of holism is the core idea of traditional Chinese medicine （TCM）. Various organs and tissues coordinate with each other to maintain the body's life activities， with a close and mutual influence between the spleen， stomach， and the central nervous system （brain）. The gut-brain axis plays an important bridging role between the digestive system and the central nervous system， achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence， coordination， and integration between different organs and systems； multimodality， on the other hand， utilizes multiple sensory modalities， such as vision， hearing， and touch， to convey information. By combining TCM theory with the gut-brain axis theory， a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders， precancerous gastrointestinal diseases， Alzheimer's disease， Parkinson's syndrome， type 2 diabetes， and depression.

BACKGROUND:Stand-alone oblique lateral interbody fusion has a high rate of complications of fusion segment sink.Oblique lateral interbody fusion with posterior fixation can provide stable support,but intraoperative position changes and double incisions weaken the advantages of this technique.Oblique lateral interbody fusion combined with lateral plate fixation can achieve one-stage decompression in the same incision,while the lateral internal fixation provides stable support. OBJECTIVE:To analyze the short-term efficacy of oblique lateral interbody fusion combined with lateral plate fixation in the treatment of single-level lumbar degenerative disease. METHODS:The clinical data of 34 patients with single-level lumbar degenerative disease treated with oblique lateral interbody fusion combined with lateral plate fixation were collected from May 2020 to October 2022.Among them,14 were males and 20 were females aged from 41 to 72 years at the mean age of(58.6±9.9)years.There were 11 cases of lumbar spondylolisthesis(Ⅰ°),7 cases of lumbar disc herniation with segmental instability,and 16 cases of lumbar spinal stenosis.Operation time,blood loss,and complications were recorded.Visual analog scale scores of lumbago,radiative pain of both lower limbs,and Oswestry disability index scores were evaluated before surgery,3 months after surgery,and the last follow-up.Dural sac cross-sectional area,intervertebral height,and intervertebral fusion were measured and observed. RESULTS AND CONCLUSION:(1)The 34 patients were followed up for 14-36 months,with an average of(21.3±5.2)months.(2)The operation time ranged from 50 to 92 minutes,with an average of(68.5±11.1)minutes.Intraoperative blood loss was 50-170 mL,with an average of(71.6±25.3)mL.(3)Compared with the preoperative results,the visual analog scale scores and Oswestry disability index scores were significantly decreased at 3 months after surgery and at the last follow-up(P<0.001),and the maximum Oswestry disability index scores were improved by nearly 50％.(4)Bone fusion was achieved in all patients during half-year follow-up.The overall complication rate was 21％(7/34),including 1 case of plate displacement,3 cases of cage subsidence,1 case of psoas weakness,and 2 cases of anterior thigh pain.(5)It is concluded that oblique lateral interbody fusion combined with lateral plate fixation for the treatment of lumbar degenerative diseases has the characteristics of less blood loss,short operation time,rapid postoperative recovery,and significant short-term clinical efficacy with the stable support to a certain extent.The long-term curative effect needs further follow-up observation.

Blue light inactivation technology, particularly at the 405 nm wavelength, has demonstrated distinct and multifaceted mechanisms of action against both Gram-positive and Gram-negative bacteria, offering a promising alternative to conventional antibiotic therapies. For Gram-positive pathogens such as Bacillus cereus, Listeria monocytogenes, and methicillin-resistant Staphylococcus aureus (MRSA), the bactericidal effects are primarily mediated by endogenous porphyrins (e.g., protoporphyrin III, coproporphyrin III, and uroporphyrin III), which exhibit strong absorption peaks between 400-430 nm. Upon irradiation, these porphyrins are photoexcited to generate cytotoxic reactive oxygen species (ROS), including singlet oxygen, hydroxyl radicals, and superoxide anions, which collectively induce oxidative damage to cellular components. Early studies by Endarko et al. revealed that (405±5) nm blue light at 185 J/cm² effectively inactivated L. monocytogenes without exogenous photosensitizers, supporting the hypothesis of intrinsic photosensitizer involvement. Subsequent work by Masson-Meyers et al. demonstrated that 405 nm light at 121 J/cm² suppressed MRSA growth by activating endogenous porphyrins, leading to ROS accumulation. Kim et al. further elucidated that ROS generated under 405 nm irradiation directly interact with unsaturated fatty acids in bacterial membranes, initiating lipid peroxidation. This process disrupts membrane fluidity, compromises structural integrity, and impairs membrane-bound proteins, ultimately causing cell death. In contrast, Gram-negative bacteria such as Salmonella, Escherichia coli, Helicobacter pylori, Pseudomonas aeruginosa, and Acinetobacter baumannii exhibit more complex inactivation pathways. While endogenous porphyrins remain central to ROS generation, studies reveal additional photodynamic contributors, including flavins (e.g., riboflavin) and bacterial pigments. For instance, H. pylori naturally accumulates protoporphyrin and coproporphyrin mixtures, enabling efficient 405 nm light-mediated inactivation without antibiotic resistance concerns. Kim et al. demonstrated that 405 nm light at 288 J/cm² inactivates Salmonella by inducing genomic DNA oxidation (e.g., 8-hydroxy-deoxyguanosine formation) and disrupting membrane functions, particularly efflux pumps and glucose uptake systems. Huang et al. highlighted the enhanced efficacy of pulsed 405 nm light over continuous irradiation for E. coli, attributing this to increased membrane damage and optimized ROS generation through frequency-dependent photodynamic effects. Environmental factors such as temperature, pH, and osmotic stress further modulate susceptibility, sublethal stress conditions (e.g., high salinity or acidic environments) weaken bacterial membranes, rendering cells more vulnerable to subsequent ROS-mediated damage. The 405 nm blue light inactivates drug-resistant Pseudomonas aeruginosa through endogenous porphyrins, pyocyanin, and pyoverdine, with the inactivation efficacy influenced by bacterial growth phase and culture medium composition. Intriguingly, repeated 405 nm exposure (20 cycles) failed to induce resistance in A. baumannii, with transient tolerance linked to transient overexpression of antioxidant enzymes (e.g., superoxide dismutase) or stress-response genes (e.g., oxyR). For Gram-positive bacteria, porphyrin abundance dictates sensitivity, whereas in Gram-negative species, membrane architecture and accessory pigments modulate outcomes. Critically, ROS-mediated damage is nonspecific, targeting DNA, proteins, and lipids simultaneously, thereby minimizing resistance evolution. The 405 nm blue light technology, as a non-chemical sterilization method, shows promise in medical and food industries. It enhances infection control through photodynamic therapy and disinfection, synergizing with red light for anti-inflammatory treatments (e.g., acne). In food processing, it effectively inactivates pathogens (e.g., E. coli, S. aureus) without altering food quality. Despite efficacy against multidrug-resistant A. baumannii, challenges include device standardization, limited penetration in complex materials, and optimization of photosensitizers/light parameters. Interdisciplinary research is needed to address these limitations and scale applications in healthcare, food safety, and environmental decontamination.

BACKGROUND:Growth factor is the key effect molecule that plays a role in platelet-rich plasma in clinical treatment.There are differences in the concentration of growth factor after different activators activate platelet-rich plasma,which is an important factor affecting clinical efficacy. OBJECTIVE:To analyze the influence of different activators on the mass concentration of growth factors in platelet-rich plasma. METHODS:Totally 12 healthy volunteers were recruited to collect EDTA-K2 anticoagulant venous blood.Secondary centrifugation was used to prepare platelet-rich plasma.The difference in mass concentrations of growth factors was compared between venous blood and platelet-rich plasma.The platelet-rich plasma was mixed with four activators(normal saline,thrombin,calcium gluconate,calcium gluconate+thrombin)according to the volume ratio of 10:1,and incubated in a constant temperature water bath at 37 °C for 30 minutes.After centrifugation,the supernatant was extracted and the mass concentration of growth factor was detected.The bacterial growth in supernatant was measured by blood agar plate.Pearson correlation was used to analyze the correlation between different activators and the mass concentration of growth factor in platelet-rich plasma,and the correlation between the value of thrombocytometer and the mass concentration of growth factors in platelet-rich plasma. RESULTS AND CONCLUSION:(1)The mass concentrations of platelet-derived growth factor-BB,platelet-derived growth factor-AB,vascular endothelial growth factor,and epidermal growth factor in platelet-rich plasma were 8.7,22.2,2.3,and 2.8 times of those in venous blood,respectively(P<0.05).(2)Compared with normal saline group,the mass concentrations of platelet-derived growth factor BB,platelet-derived growth factor AB,vascular endothelial growth factor,and epidermal growth factor were increased in the thrombin group,calcium gluconate group,and calcium gluconate+thrombin group(P<0.05).The mass concentration of platelet-derived growth factor BB in the thrombin group and calcium gluconate group was higher than that in the calcium gluconate+thrombin group(P<0.05),and the mass concentration of platelet-derived growth factor AB in the thrombin group was higher than that in the calcium gluconate group and calcium gluconate+thrombin group(P<0.05).Epidermal growth factor mass concentration in the thrombin group was lower than that in the calcium gluconate group and calcium gluconate+thrombin group(P<0.05).(3)The results of blood agar plate test showed no bacterial growth in the supernatant of the four groups.(4)Pearson correlation analysis showed that the mass concentration of platelet-derived growth factor BB in platelet-rich plasma was strongly positively correlated with thrombin(r=0.683,P<0.05),and the mass concentration of vascular endothelial growth factor was strongly positively correlated with thrombin,calcium gluconate,calcium gluconate+thrombin stimulant(r=0.730,0.789,0.686,P<0.05).There was no correlation between the value of thrombocytometer and the mass concentration of four kinds of growth factors(P>0.05).(5)The results suggest that different activators have an impact on the concentration of growth factors in platelet-rich plasma.It is suggested to choose different activators to improve clinical efficacy according to different growth factor mass concentrations and treatment needs.
