This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

Objective: To investigate the effect of neurite outgrowth inhibitor extracellular peptide residues 1-40 (NEP1-40) combined with poly (lactic-co-glycolic acid) (PLGA) and gelatin electrospun fiber membrane on facial nerve repair in rats. Methods: According to the principle of random grouping, 108 male SD rats were divided into four groups (n = 27 in each group, approved by the ethics committee), namely, the sham group, control group, PLGA group, and NEP1-40 + PLGA group. A facial nerve fracture model was established for all of the groups except for the sham group. The control group received no further treatment, the PLGA group and the NEP1-40+PLGA group were supported by PLGA membrane, and the NEP1-40+PLGA group received one immediate local injection of NEP1-40 (5 μg/μL) at a dose of 10 μL. Facial nerve function analysis, electrophysiological examination, transmission electron microscope observation, HE staining, and immunohistochemical staining of myelin marker S100β and axonal marker β3-tubulin were used to evaluate the recovery of injured facial nerves of rats at 2, 4 and 8 weeks. Results : At 8 weeks, the facial nerve function score of the NEP1-40+PLGA group was better than that of the control group and PLGA group (P < 0.001), and facial nerve function was significantly restored. Electrophysiological examination of nerve action potentials at the injured facial nerve showed that the amplitude in the NEP1-40+PLGA group was higher than that of the control group and PLGA group (P < 0.001), but there was no significant difference in latency and conduction velocity results between the groups (P > 0.05). At 2, 4, and 8 weeks, transmission electron microscopy showed that the number of myelinated nerve fibers and myelin sheath thickness in the cross-section of the injured facial nerve in the NEP1-40+PLGA group were greater than those in the other groups (P < 0.05). At 8 weeks, HE staining showed that the facial nerves in the control group had partially recovered, but the overall cell distribution was uneven and the boundary with surrounding tissues was slightly blurred. In contrast, the NEP1-40+PLGA group had a relatively uniform cell distribution and a clearer boundary with surrounding tissues. At 2, 4, and 8 weeks, the immunohistochemical results showed that in the cross-section of the injuried facial nerve, NEP1-40 increased the expression of neural markers S100 β and β3-tubulin, especially β3-tubulin, which was close to normal levels (P > 0.05) Conclusion NEP1-40 is beneficial for the generation of new myelin sheaths and axons at the site of injury, and it can promote the repair and regeneration of injured facial nerves to a certain extent, thus accelerating the recovery of injured nerve function.

Objective Jiedu Tongluo Tiaogan Formula(JTTF)is an effective formula for the clinical treatment of type 2 diabetes mellitus(T2DM).We used integrated pharmacology and in vitro experiments to explore the molecular mechanism of JTTF to improve insulin resistance(IR)in T2DM.Methods The drug targets of JTTF were obtained by identifying the key active ingredients of JTTF through UPLC-Q-TOF-MS.Multiple databases such as GeneCards,OMIM,and DrugBank were used to screen T2DM-IR related targets.Cytoscape software and String 11.0 database were used to construct the PPI network diagram of JTTF for T2DM-IR.GO and KEGG analyses were performed according to the Metascape platform to find the biological pathways related to the target proteins.AutoDock Tools software was used to simulate molecular docking.In vitro experiments were performed using palmitic acid(PA)-induced HepG2-IR cell model to detect the effect of JTTF on HepG2-IR.Results 28 effective active components of JTTF were screened.There were 857 gene targets of T2DM-IR,and 168 targets of drug-disease intersection.387 GO entries and 145 KEGG pathways were enriched.The molecular docking results showed that the main components of JTTF had good binding activities with PI3K and AKT-related proteins.The in vitro results showed that JTTF significantly alleviated PA-induced HepG2 cell injury,increased HepG2 glucose consumption,increased PI3K and AKT mRNA and protein expression,regulated the expression of GLUT2,GLUT4 and GSK3β,and improved cellular IR.Conclusion JTTF increases insulin sensitivity of HepG2-IR cells,promotes glucose uptake and intracellular glucose metabolism process,and its mechanism of action may be related to the up-regulation of PI3K/AKT signalling pathway.

Objective To investigate the factors influencing poor prognosis in patients with persistent atrial fibrillation combined with heart failure undergoing catheter ablation.Methods The clinical data of 166 patients with persistent atrial fibrillation who underwent elective radiofrequency ablation in the Department of Cardiology of our hospital from January 2023 to June 2024 were retrospectively analyzed.Patients who under-went radiofrequency ablation and developed persistent atrial fibrillation were placed in the poor prognosis group(n=89),and those who did not develop heart failure were placed in the control group(n=77).Logistic regression analysis was used to identify factors influencing poor prognosis in patients with persistent atrial fi-brillation after catheter ablation;latent class analysis(LCA)was used to compare differences in the distribu-tion characteristics of influencing factors between the high-risk group for poor prognosis[B-type natriuretic peptide(BNP)>200 pg/mL]and the low-risk group(BNP≤200 pg/mL).Results There were statistically significant differences between the two groups of patients in terms of age,use of ACEI/ARB medications,dis-ease course,postoperative NYHA cardiac function classification,use of ivabradine,preoperative TG,preopera-tive TC,preoperative HDL-C,preoperative serum cholinesterase,preoperative galectin-3,preoperative LVEF,preoperative NT-proBNP,preoperative cTnI,and preoperative BNP(P<0.05).A disease course≥3.2 years,postoperative NYHA cardiac function classification score≥2 points,preoperative HDL-C<1.05 mmol/L,preoperative NT-proBNP≥12.5 μg/L,and preoperative BNP≥200.00 pg/mL were independent factors in-fluencing adverse outcomes in patients with persistent atrial fibrillation(P<0.05).LCA results showed that the"high-risk type distribution"accounted for a higher proportion in the high-risk group,while the"low-risk type distribution"accounted for a higher proportion in the low-risk group.The incidence of clinical endpoint e-vents in the poor prognosis group was 38.20%,higher than 9.09%in the control group(P<0.05).Conclu-sion Heart failure has an adverse effect on the prognosis of patients with persistent atrial fibrillation after catheter ablation,and there are differences in the incidence of adverse outcomes as well as the distribution characteristics of influencing factors between high-and low-risk groups.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
