Diabetic kidney disease （DKD） is one of the most common microvascular complications of diabetes. Traditional Chinese medicine （TCM） plays a unique role in improving clinical symptoms， reducing proteinuria， and delaying the initiation of dialysis. Over time， scholars have held diverse views on the etiology， pathogenesis， and treatment strategies of DKD. This paper systematically reviews the etiology and pathogenesis， syndrome differentiation and treatment， and medication rules of DKD， aiming to provide a reference for clinical practice. Regarding etiology， DKD is closely related to insufficient innate endowment， improper diet， emotional disorders， overexertion， and prolonged diabetes. Its pathogenesis evolves dynamically. Specifically， early stage is characterized by Yin deficiency with dryness-heat and subtle discharge. Middle stage involves both Qi and Yin deficiency with dampness and blood stasis. Late stage presents Yin and Yang deficiency with intrinsic turbidity toxins. Blood stasis and sugar toxicity are the core pathological factors， persisting throughout the disease course and accelerating renal collateral damage and fibrosis. In terms of diagnosis and treatment， contemporary scholars advocate stage-specific treatment， emphasize the integration of prevention and therapy， recommend whole-course management， and support comprehensive TCM and Western medicine approaches. Analysis of medication rules shows that treatment consistently addresses the core principle of deficiency at the root and excess at the surface， strengthens the body while dispelling pathogenic factors， emphasizes promoting blood circulation and removing blood stasis， consolidates the kidney and astringes essence， clears Fu-organs and eliminates turbidity and toxins， invigorates the spleen， replenishes Qi， protects the stomach， and advocates treatment based on pathogenic wind. Further refinement of the academic thoughts of classical TCM masters and research into innovative pathogenesis theories and clinically effective prescriptions are needed to enhance TCM's ability to prevent and treat major clinical diseases， including DKD.

OBJECTIVE: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pain in patients undergoing modified radical mastectomy for breast cancer. METHODS: A total of 140 female patients scheduled for unilateral modified radical mastectomy for breast cancer undergoing general anesthesia were randomized into a TEAS group (70 cases) and a sham TEAS group (70 cases, 2 cases dropped out). Patients in both groups received TEAS or sham TEAS at bilateral Neiguan (PC6), Zusanli (ST36), and Danzhong (CV17), respectively, from 30 min before anesthesia induction until the end of surgery, and on 1st, 2nd, and 3rd days after surgery for 30 min a time, once a day. On 1st, 2nd, and 3rd days after surgery, the pain visual analogue scale (VAS) score was observed; on 3, 6, 12 months after surgery, the incidence rate of chronic pain was observed; before surgery, and on 1st, 3rd, and 7th days after surgery, the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 were detected; the number of analgesia pump press, rescue analgesia, and the occurrence of adverse reaction after surgery were recorded in the two groups. RESULTS: In the TEAS group, the VAS scores on 1st and 2nd days after surgery, and the incidence rates of chronic pain on 3 and 6 months after surgery were lower than those in the sham TEAS group (P<0.05). On 1st, 3rd, and 7th days after surgery, the serum levels of TNF-α, IL-6, and IL-10 were increased compared with those before surgery in both groups (P<0.05, P<0.01); the above indexes in the TEAS group were lower than those in the sham TEAS group (P<0.05). The number of analgesia pump press and the incidence rate of rescue analgesia after surgery in the TEAS group were lower than those in the sham TEAS group (P<0.05). There was no statistically significant difference in the incidence of adverse reactions after surgery between the two groups (P>0.05). CONCLUSION TEAS can effectively improve both the postoperative acute pain and chronic pain in patients undergoing modified radical mastectomy for breast cancer, the mechanism may relate to inhibiting the inflammatory reaction.

OBJECTIVES: To investigate the changes in blood levels of calcium and bone metabolism biochemical markers in patients with primary osteoporosis receiving treatment with denosumab. METHODS: Seventy-three patients with primary osteoporosis treated in our Department between December, 2021 and December 2023 were enrolled. All the patients were treated with calcium supplements, vitamin D and calcitriol in addition to regular denosumab treatment every 6 months. Blood calcium, parathyroid hormone (PTH), osteocalcin (OC), type I procollagen amino-terminal propeptide (PINP), and type I collagen carboxy-terminal telopeptide β special sequence (β‑CTX) data before and at 3, 6, 9, and 12 months after the first treatment were collected from each patient. RESULTS: Three months after the first denosumab treatment, the bone turnover markers (BTMs) OC, PINP, and β-CTX were significantly decreased compared to their baseline levels by 39.5% (P<0.001), 56.2% (P<0.001), and 81.8% (P<0.001), respectively. At 6, 9, and 12 months of treatment, OC, PINP, and β-CTX remained significantly lower than their baseline levels (P<0.001). Blood calcium level was decreased (P<0.05) and PTH level increased (P<0.05) significantly in these patients at months of denosumab treatment, but their levels were comparable to the baseline levels at 6, 9, and 12 months of the treatment (P>0.05). CONCLUSIONS Denosumab can suppress BTMs and has a good therapeutic effect in patients with primary osteoporosis, but reduction of blood calcium and elevation of PTH levels can occur during the first 3 months in spite of calcium supplementation. Blood calcium and PTH levels can recover the baseline levels as the treatment extended, suggesting the importance of monitoring blood calcium and PTH levels during denosumab treatment.

Glucose transporters (GLUTs) are pivotal membrane proteins that facilitate the passive transport of glucose into cells. However, their aberrant overexpression is closely linked to the Warburg effect and chemotherapy resistance of tumors. GLUTs are complex multi-pass transmembrane proteins that require detergents for extraction from the cell membrane during preparation. The persistent presence of detergents in the sample can disrupt lipid-protein interactions, potentially leading to conformational distortion and functional losses of GLUTs, severely hindering the research into their structures and transport mechanisms. To eliminate detergent interference and preserve its authentic conformation, this study employs nanodisc technology and utilizes the self-assembly of the membrane scaffold protein MSP1E3D1 and phospholipids to produce a biomimetic membrane environment, thereby overcoming the limitations of conventional methods. The C-terminal His10-tagged GLUT1 was heterologously expressed in the insect cell Sf9/Bac-to-Bac system, and the GLUT1-nanodisc complex was obtained after detergent solubilization, affinity chromatography purification via anti-His antibody resin, and self-assembly. The successfully reconstituted nanodisc complex was further purified by Ni-NTA affinity chromatography. Nanodisc reconstitution produced monodisperse GLUT1 particles that retained native secondary structure, as confirmed by far-UV circular dichroism (CD) spectroscopy and dynamic light scattering (DLS). Unlike conventional detergent micelles, which lack a true lipid bilayer, distort transmembrane-helix topology, and occlude ligand-binding sites, the nanodisc platform embeds GLUT1 in a phospholipid bilayer that preserves its authentic conformation while eliminating detergent interference. The resulting GLUT1-nanodisc complex is therefore a superior scaffold for high-resolution cryo-EM structural analysis, permitting detailed interrogation of the transporter's conformational cycle, its interactions with partner proteins, and downstream structure-guided, high-throughput drug screening.

Polycystic ovary syndrome（PCOS） is a common reproductive endocrine and metabolic disorder， affecting about 6%-10% of women of childbearing age worldwide， and has always been a major challenge in clinical treatment. Guizhi Fulingwan， derived from the Synopsis of the Golden Chamber（《金匮要略》）， has the effect of promoting blood circulation， removing blood stasis， and alleviating blockages. In recent years， many studies have found that it has a good therapeutic effect on PCOS. By sorting out the research literature on the mechanism of Guizhi Fulingwan treating PCOS， it is found that this formula can decrease the autophagy and apoptosis of ovarian granulosa cells， correct endocrine hormone disorder， improve the inflammatory environment， alleviate oxidative stress. Moreover， it regulates phosphatidylinositide 3-kinase（PI3K）/protein kinase B（Akt）/mammalian target of rapamycin（mTOR）， lncRNA H19/miR-29b-3p， nuclear factor E₂-related factor 2（Nrf2）/heme oxygenase-1（HO-1）， PI3K/Akt/nuclear factor-κB（NF-κB）， and other signaling pathways. And also effects the regulator expression of matrix metallopeptidase-9（MMP-9）， matrix metalloproteinase inhibitor-1（TIMP-1）， cytochrome P45019A1 enzyme（CYP19A1）， glucose transporter protein 4（GLUT4）， regulated on activation normal T cell expressed and secreted（RANTES）， monocyte chemoattractant protein-1（MCP-1）. Thus， Guizhi Fulingwan is confirmed to treat PCOS based on these molecular mechanisms. Besides， the main active ingredients of the formula such as cinnamic aldehyde， （+）-catechin， stigmasterol， also have the effect of anti-oxidant， anti-inflammatory， regulating mitochondrial function， regulating endocrine， and regulating metabolism. According to the summary of clinical literature on Guizhi Fulingwan， it is found that the use of the formula alone or in combination with other drugs can significantly alleviate the clinical symptoms and complications of PCOS. Thus， it is safe with no adverse reactions in long-term use， which is worthily further promoted in clinical application. This paper comprehensively analyzed the current research status of Guizhi Fulingwan for the treatment of PCOS through the mechanism and clinical studies， summarized the limitations in current research， and put forward suggestions， aiming to provide the strong literature support for the future in-depth research on and clinical application of the formula.

Objective:To investigate the predictive value of preoperative D-dimer level for futile recanalization (FR) after mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS).Methods:It was a nested case-control study. A total of 116 patients with large vessel occlusion (LVO) stroke, who underwent successful recanalization (modified Thrombolysis in Cerebral Infarction, mTICI≥2b) after MT at the Stroke Unit of Beijing Hospital from August 2018 to January 2022,were consecutively enrolled, including 72 males (62.1%) with the age of (72.8±13.1) years. According to the 3-month modified Rankin Scale (mRS) score after MT, patients were divided into the meaningful recanalization group (mRS 0-2, n=41) and the futile recanalization group (mRS 3-6, n=75). The baseline clinical data of enrolled patients was collected. Logistic regression analysis was used to identify the independent risk factors for FR after MT in patients with AIS. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of D-dimer for FR. Results:Multivariate logistic regression analysis showed that high baseline systolic blood pressure (SBP) ( OR=1.038, 95% CI: 1.012-1.065, P=0.004), baseline National Institutes of Health Stroke Scale (NIHSS) score≥12 ( OR=10.157, 95% CI: 3.624-28.470, P<0.001) and high preoperative D-dimer level ( OR=4.536, 95% CI: 1.379-14.922, P=0.013) were independent predictors of FR after MT in AIS patients with LVO. ROC curve analysis indicated a good predictive value of preoperative D-dimer for the occurrence of FR ( AUC=0.733, 95% CI: 0.638-0.829, P<0.05), the optimal cut-off value of D-dimer was 2.65 μg/L(Lg), with the Youden index, sensitivity, specificity and accuracy of 0.435, 53.3%, 90.2% and 66.4%, respectively. Conclusion:High preoperative D-dimer level is an independent predictor of futile recanalization after MT in AIS patients with LVO, which shows good predictive ability for futile recanalization.
