With the rising incidence of diabetes， diabetic kidney disease （DKD） has become a significant global health burden. Although current prevention and treatment strategies can partially delay the progression of DKD， the risk of patients advancing to end-stage renal disease remains high. Since the concept of the "gut-kidney axis" was first introduced at the International Congress on Dialysis in 2011， research on the role of gut microbiota in the pathogenesis of DKD has received increasing attention. This review summarizes the current research on gut microbiota， explores the mechanisms through which it contributes to DKD development， and outlines clinical approaches for DKD prevention and treatment based on the "gut-kidney axis" theory. Evidence indicates that dietary interventions， intake of probiotics or prebiotics， use of metformin and novel antidiabetic drugs， and application of traditional Chinese medicine （TCM） compound formulas can effectively improve gut microbiota composition， influence metabolite production， and restore the intestinal mucosal barrier. These interventions can further regulate intestinal innate immunity and inflammatory responses， thereby modulating the progression of DKD. Despite challenges posed by the traditional oral administration of water-decocted TCM compound formulas and the complexity of their ingredients， increasing evidence suggests that TCM may indirectly affect the occurrence and development of DKD by modulating gut microbiota. This finding provides a new perspective on the potential mechanisms of TCM in DKD treatment and may offer novel strategies for DKD prevention and therapy.

ObjectiveTo investigate the clinical efficacy and mechanisms of Qigui Didang decoction in the treatment of kidney collateral stasis syndrome in patients with stage Ⅲ-Ⅳ diabetic kidney disease （DKD） in a real-world setting. MethodsPatients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome admitted to Beijing Aerospace General Hospital from January 2022 to December 2024 were selected for clinical study. According to treatment methods， patients were divided into the Qigui Didang decoction group （Qigui Didang decoction + conventional treatment） and the control group （conventional treatment alone）. A 1∶1 propensity score matching （PSM） method was used to reduce bias caused by confounding factors. Clinical efficacy， traditional Chinese medicine （TCM） symptom scores， renal function indicators， mRNA expression related to pathway mechanisms， glycolipid metabolism indices， and adverse reactions were compared between the two groups. ResultsA total of 120 patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome were included， including 62 cases in the Qigui Didang Decoction group and 58 cases in the control group. Before matching， there were statistically significant differences between the two groups in DKD stage， baseline urinary albumin-to-creatinine ratio （UACR）， 24-hour urine total protein （24 h-UTP）， and estimated glomerular filtration rate （eGFR） （P<0.05）. After matching， 47 cases were included in each group， and there was no statistically significant difference in baseline data between the two groups. After matching， the total clinical effective rate of the Qigui Didang decoction group was significantly higher than that of the control group （χ²=4.681， P<0.05）. Compared with data before treatment， the scores of primary and secondary TCM symptoms in the Qigui Didang decoction group were significantly decreased （P<0.05）. Compared with data before treatment， serum creatinine （SCr）， 24 h-UTP， and UACR levels were significantly decreased， while eGFR was significantly increased in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， the mRNA expression of silent information regulator 1 （Sirt1） was significantly upregulated， while the mRNA expression of nuclear factor-kappa B （NF-κB） and tumor suppressor protein p53 （p53） was significantly downregulated in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， fasting plasma glucose （FPG）， 2-hour postprandial plasma glucose （2 hPG）， glycated hemoglobin A1c （HbA1c）， total cholesterol （TC）， triglycerides （TG）， and low-density lipoprotein cholesterol （LDL-C） levels were decreased， while high-density lipoprotein cholesterol （HDL-C） levels were increased （P<0.05）. There was no statistically significant difference in adverse reactions between the two groups. ConclusionQigui Didang decoction combined with conventional treatment can significantly improve renal function， glycolipid metabolism， and TCM syndromes in patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome， with good safety. The mechanism may be related to the regulation of the Sirt1/NF-κB/p53 signaling pathway.

Based on the theory of "three regions and sanjiao" in traditional Chinese medicine (TCM), the acupuncture-moxibustion differentiation and treatment system is explored and constructed for spasm syndrome, so as to provide a clearer guiding framework for TCM treatment of spasm syndrome. This disorder is caused essentially by the invasion of pathogenic wind, and located in brain marrow. The key regions of illness cover five zang organs and five tissues, and the core pathogenesis is associated with wind disturbance in brain marrow. In differentiation, spasm syndrome refers to overall transmission (from the upper to the lower) and local transmission (from exterior to interior). This disorder can be classified into sanjiao spasm (heart-lung spasm of the upper jiao, liver-spleen spasm of the middle jiao, and liver-kidney spasm of the lower jiao) and three-region spasm (skin-vessel spasm of the upper region, tendon-muscle spasm of the middle region, and tendon-bone spasm of the lower region). Based on "three regions and sanjiao" theory of acupuncture and moxibustion, 7 "expelling-wind" points can be selected in terms of the etiology of this disease. Baihui (GV20)-toward-Taiyang (EX-HN5) needling is applied to regulate the brain marrow, focusing on the core location of illness; and regarding the key location of illness, the combination of back-shu and front-mu points and that of jing-well and xing-spring points are adopted to regulate five zang organs. The five needling techniques (half needling, leopard-spot needling, joint needling, Hegu needling and shu needling) are used to regulate five tissues.

Objective:To evaluate the relationship between sevoflurane preconditioning-induced reduction of cognitive impairment and hippocampal necroptosis after cardiopulmonary bypass (CPB) in rats.Methods:Sixty SPF healthy male Sprague-Dawley rats, aged 6 months, weighing 400-450 g, were divided into 4 groups ( n=15 each) using the random number table method: control group (group C), sevoflurane group (Sev group), CPB group and CPB+ sevoflurane preconditioning group (CPB+ Sev group). The rats were exposed to 0.4% sevoflurane for 2 h in CPB+ Sev group and Sev group. The CPB model was established at 30 min after the end of sevoflurane preconditioning in CPB+ Sev group. The open field test was performed to assess the autonomic movement ability on the 2nd day after CPB. The Morris water maze test was used to assess the cognitive function on the 3rd day after CPB. The hippocampal tissues were removed after the end of the Morris water maze test for determination of the necroptosis rate and cytosolic calcium concentration of hippocampal neuron ([Ca 2+ ] i) (by flow cytometry) and the expression of phosphorylated receptor-interacting protein kinase 1 (p-RIPK1), phosphorylated RIPK3 and phosphorylated mixed-lineage kinase-like domain (p-MLKL) (by Western blot) and for microscopic examination of the ultrastructure of hippocampal neurons (by transmission electron microscopy). Results:There was no statistically significant difference in the parameters of the open field test among the four groups ( P>0.05). Compared with group C, the escape latency was significantly prolonged, the number of crossing the original platform was decreased, the time of staying at the original platform quadrant was shortened, the hippocampal necroptosis rate and [Ca 2+ ] i were increased, the expression of p-RIPK1, p-RIPK3 and p-MLKL was up-regulated ( P<0.05), the organelles of hippocampal neurons swelled, lysosomes broke, and some chromatin in nuclei dissoluted in CPB group. Compared with CPB group, the escape latency was significantly shortened, the number of crossing the original platform was increased, the time of staying at the original platform quadrant was prolonged, the hippocampal necroptosis rate and [Ca 2+ ] i were decreased, the expression of p-RIPK1, p-RIPK3 and p-MLKL was down-regulated ( P<0.05), and the damage to the ultrastructure of hippocampal neurons was sinificantly reduced in CPB+ Sev group ( P<0.05). Conclusions:The mechanism by which sevoflurane preconditioning attenuates cognitive impairment may be related to the inhibition of calcium overload-mediated hippocampal necroptosis in a rat model of CPB.

Case 1 A 68-year-old male patient presented with poor appetite persisting for over 2 months and had been diagnosed with liver cancer 7 days prior. He was admitted to Liaocheng Second People′s Hospital on October 17, 2017. On October 18, 2017, at 8:00, the patient underwent transcatheter arterial chemoembolization under local anesthesia. At 17:30, the patient developed a fever. At 20:00, "port wine-colored" urine was noted during catheterization, prompting transfer to the intensive care unit (ICU) for enhanced treatment. Case 2 A 67-year-old male patient with a previous diagnosis of hilar cholangiocarcinoma presented to the Emergency Department of Liaocheng Second People′s Hospital at 17:40 on March 25, 2025, due to "unconsciousness for one hour". Routine blood testing revealed significantly decreased white blood cells, red blood cells, and platelets. Considering the critical condition, the patient was transferred to the ICU. At 19:30, "port wine-colored" urine was observed in the urinary catheter. Both cases showed evident signs of hemolysis in blood samples, rapid disease progression, with fatal outcomes occurring within a short period. Blood cultures from both patients signaled positive in anaerobic bottles. Identification using the bioMérieux VITEK 2 COMPACT ANC card confirmed Clostridium perfringens. Bloodstream infections caused by Clostridium perfringens leading to such severe intravascular hemolysis are rare. The disease course is notoriously aggressive. In clinical practice, early recognition of this infection is paramount.
