Oxidative stress is a pivotal factor in the onset and progression of diabetic kidney disease (DKD), and it plays an essential role in the prevention and treatment of DKD. The "Gaozhuo" pathogenesis posits that DKD is characterized by the invasion of Gaozhuo and damage to the kidney collaterals, with the underlying cause being the insufficiency of spleen Qi and the internal formation of Gaozhuo, which provides valuable guidance on oxidative stress. The insufficiency of spleen Qi and the internal formation of Gaozhuo represent a dynamic, evolving process. Gaozhuo invades the kidney collaterals, impairs kidney Qi, and progressively leads to the congealing and stagnation of Gaozhuo and blood, ultimately resulting in the failure of both the spleen and kidneys. The damage caused by Gaozhuo to the kidney collaterals and kidney Qi is analogous to the organ and functional damage of the kidneys induced by excessive reactive oxygen species and oxidative stress. Damage to the kidney collaterals means organic injuries to the glomeruli, renal tubules, and renal interstitium, and the depletion of kidney Qi refers to damage to glomerular filtration and renal tubular reabsorption. The congealing and stagnation of Gaozhuo and blood in the kidney collaterals is similar to oxidative stress-induced thickening of the glomerular basement membrane and fibrosis. The interaction between spleen and kidney Qi deficiency and the congealing and stagnation of Gaozhuo and blood creates a vicious cycle that exacerbates the condition, ultimately evolving into the failure of both the spleen and kidneys. The failure of the spleen and kidneys is analogous to renal failure, and its extreme manifestation is end-stage renal disease and uremia. The treatment of oxidative stress in DKD with traditional Chinese medicine (TCM) is based on the principles of strengthening the spleen and tonifying the kidneys, and dispelling turbidity and removing blood stasis. According to the syndrome type, it is recommended to use methods such as strengthening the spleen and tonifying Qi while dispelling dampness and removing turbidity, strengthening the spleen and tonifying the kidneys while dispelling dampness and removing turbidity, strengthening the spleen and tonifying the kidneys while dispelling turbidity and removing blood stasis, or consolidating the spleen and kidneys while clearing away turbidity and blood stasis.

Diabetic cardiomyopathy (DCM) is one of the most common complications of diabetes mellitus and is a major threat to global health. As a key mechanism in the occurrence and progression of DCM, the inflammatory response persists throughout the entire course of the DCM. The Gaozhuo theory suggests that the basic pathogenesis of inflammatory injury in DCM is the Qi deficiency of spleen and kidney and Gaozhuo invasion, and divides the pathological process into three phases: Gaozhuo invasion, turbid heat damage to the channels, and turbid blood stasis and heat junction. Among them, the Qi deficiency of spleen and kidney and the endogenous formation of Gaozhuo represent the process of inflammatory factor formation induced by glucose metabolism disorders. Turbid heat damage to the channels refers to the process of myocardial inflammatory injury mediated by inflammatory factors, and turbid blood stasis and heat junction are the process of myocardial injury developing toward myocardial fibrosis and ventricular remodeling. As the disease continues to progress, it eventually develops into a depletion of the heart Yang, leading to the ultimate regression of heart failure. According to the theory of Gaozhuo, traditional Chinese medicine (TCM) should regulate inflammatory injury in DCM by strengthening the spleen and tonifying the kidney to address the root cause, and resolving dampness and lowering turbidity to treat the symptoms. If the turbidity has been stored for a long time and turns into heat, strengthening the spleen and tonifying the kidney, and clearing heat and resolving turbidity should be the therapy. If the turbidity, stasis, and heat are knotted in the heart and collaterals, strengthening the spleen and tonifying the kidney, and resolving stasis and lowering turbidity should be the therapy. TCM compounds and monomers can regulate the inflammatory response in DCM. TCM compounds can be divided into the categories for benefiting Qi to resolve turbidity, benefiting Qi and clearing heat to resolve turbidity, and benefiting Qi and activating blood to reduce turbidity. The compounds can inhibit upstream signals of inflammation and expression of inflammatory factors, improve the inflammatory damage to myocardium and blood vessels, myocardial fibrosis, and cardiac systole and diastole, and thus slow down the onset and progression of DCM.

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.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common complications of type 2 diabetes mellitus (T2DM), and hepatic stellate cell (HSC) activation is the key link in the progression of NAFLD to liver fibrosis. According to the theory of "Gaozhuo", spleen deficiency and Qi stagnation, along with Gaozhuo invasion, are the causes of NAFLD progression to liver fibrosis, which reveals the pathogenesis essence of HSC activation in traditional Chinese medicine (TCM). Among them, spleen deficiency and Qi stagnation are the root causes of the endogenous formation of Gaozhuo. Spleen deficiency indicates the insulin sensitivity decrease and glucose metabolism disorders, and Qi stagnation means the dysregulation of hepatic glucose and lipid metabolism, which creates the preconditions for HSC activation. Gaozhuo invasion is the direct cause of HSC activation, including three stages: Internal retention of Gaozhuo, turbidity and stasis stagnation, and toxic stasis and consolidation. Internal retention of Gaozhuo refers to the abnormal metabolism and deposition of hepatic lipids, as well as the microcirculatory disorders. Turbidity and stasis stagnation is the process by which lipotoxicity stimulates the transformation of HSC into myofibroblast (MFB), and toxic stasis and consolidation represent the secretion of a large amount of extracellular matrix (ECM) by MFB to promote the fibrosis. According to the theory of Gaozhuo and the activation process of HSC, syndromes for T2DM combined with NAFLD can be classified into spleen deficiency and Qi stagnation with internal retention of Gaozhuo, spleen Qi deficiency with turbidity and stasis stagnation, and spleen Qi deficiency with toxic stasis and consolidation. Clinically, the treatment principle is to strengthen the spleen and promote Qi, resolve turbidity, and eliminate blood stasis. Both TCM compounds and monomers can effectively inhibit the HSC activation. TCM compounds can be classified into categories for regulating spleen and harmonizing liver, resolving turbidity and removing stasis, and detoxifying and removing stasis. They mainly work by improving lipid metabolism, reducing lipid accumulation in the liver, alleviating inflammatory and oxidative stress responses, inhibiting the activation and proliferation of HSC, and reducing ECM deposition, thereby delaying the progression of liver fibrosis.

Diabetic macular edema(DME), a serious complication of diabetic retinopathy(DR), is a chronic condition caused by multiple factors. Throughout its progression, inflammatory factors and vascular endothelial growth factor(VEGF)play a critical role. Anti-VEGF drugs have shown significant effectiveness in the treatment of DME; however, some patients may experience persistent DME after injection or require frequent injections. Dexamethasone intravitreal implants(DEX implants)serve as a sustained-release implant characterized by a reasonable release profile and high bioavailability. They offer safe, effective, and prolonged anti-inflammatory effects, aiding in the repair of retinal barrier and reduction of exudation. To further enhance patients' visual quality, exploring the efficacy of DEX implants in combination with existing treatment regimens has great clinical significance. This review primarily discusses the research advancements in DEX implants, focusing on their pharmacological properties, indications for use, and their combination with existing drugs and treatment methods. It also evaluates the advantages and disadvantages of combination therapy or switching to DEX implants compared to current standard treatments, aiming to provide guidance for personalized treatment options for patients with DME.

Acute Gelsemium poisoning is a systemic disease primarily affecting the central nervous system and respiratory symptoms caused by the ingestion of a substantial amount of Gelsemium within a short period. It manifests as sudden onset and rapid progression, primarily caused by accidental ingestion due to misidentification, and posing significant health risks. The compilation of the Technical Plan for Emergency Health Response to Acute Gelsemium Poisoning describes in detail the specialized practice and technical requirements in the process of handling acute Gelsemium poisoning, including accident investigation and management, laboratory testing and identification, in-hospital treatment, and health monitoring. The guidelines clarify key procedures and requirements such as personal protection, investigation elements, etiology determination, medical rescue, and health education. The key to acute Gelsemium poisoning investigation lies in promptly identifying the toxin through exposure history, clinical manifestations, and sample testing. Because there is no specific antidote for Gelsemium poisoning, immediate removal from exposure, rapid elimination of the toxin, and respiratory monitoring are critical on-site rescue measures. Visual identification of food or herbal materials, followed by laboratory testing to determine Gelsemium alkaloids in samples is a rapid effective screening method. These guidelines offer a scientific, objective, and practical framework to support effective emergency responses to acute Gelsemium poisoning incidences.
9.Analysis of current situation and countermeasures of sex education in special education schools in Luzhou
Chinese Journal of School Health 2025;46(6):802-805
Objective:
To analyze the implementation status and challenges of sex education in special education schools, so as to provide a scientific basis for formulating effective promotion strategies.
Methods:
From November 2023 to January 2024, a census survey was conducted among 120 in service teachers from 7 special education schools in Luzhou. The questionnaire covered the current status of sex education in schools, teachers attitudes and knowledge toward sex education, and their coping methods for students inappropriate sexual behaviors.
Results:
About 77.5% of teachers reported having provided sex education to students, but 93.2% indicated a lack of specialized sex education textbooks for special children, 90.4% reported no full time teachers for sex education, and the methods of sex education were relatively limited (50.0% mainly based on lecture method). Nearly 95.8% of teachers held a positive attitude toward sex education, with 98.3% supporting its implementation. Only 26.7% of teachers demonstrated a good grasp of sex education knowledge, with the best understood topic being "recognition and protection of private parts" (21.6%). When dealing with students inappropriate sexual behaviors, the active response rate of teachers was 23.9%, with the highest active response rate observed for "intentionally hugging or kissing the opposite sex" (39.7%).
Conclusions
The special education schools in Luzhou lack comprehensive sex education curricula, teaching materials and full time teachers, sufficient knowledge among teachers, and adequate proactive responses to students inappropriate sexual behaviors. Greater emphasis should be placed on sex education for special children, including the training of dedicated teachers, to provide comprehensive and high quality sex education services for special children.
