Retinitis pigmentosa (RP) is the most common hereditary blinding eye disease in clinical practice, with the pathogenesis remaining unclear. Patients experience progressive apoptosis of retinal photoreceptor cells, accompanied by degeneration of retinal pigment epithelium (RPE) cells. Current Western medical treatments mainly focus on gene therapy and stem cell transplantation, showing limited efficacy. In contrast, clinical observations have confirmed the therapeutic effects of traditional Chinese medicine (TCM) treatments. Establishing an RP animal model that aligns with the diagnostic features of both TCM and Western medicine could help combine the strengths of both approaches, thereby broadening the treatment options for RP. This study categorizes and summarizes the existing RP animal models in terms of classification, types, inheritance patterns, and alignment with clinical manifestations. It is found that current RP models are primarily derived from natural animal models such as RD mice and RCS rats, transgenic animal models like RPE-65 knockout mice and rhodopsin gene knockout mice, and chemically induced models such as those created by monochromatic light exposure or N-ethyl-N-nitrosourea (ENU) administration. These three categories of models focus more on detecting RP-related histopathological, molecular biological, and cellular immunological indicators, but offer limited observation of the overall characteristics of the disease and lack insight into syndrome differentiation. Although RP is a congenital genetic disease, its progression is influenced by acquired factors such as environment, constitution, emotions, and care. Current models do not fully capture the characteristics of this disease. Therefore, establishing an RP animal model based on the diagnostic features of both TCM and Western medicine will have significant implications for future experimental and clinical research.

Objective:
To investigate the efficacy of magnesium-strontium co-doped hydroxyapatite mineralized collagen (MSHA/Col) in improving the bone repair microenvironment and enhancing bone regeneration capacity, providing a strategy to address the insufficient biomimetic composition and limited bioactivity of traditional hydroxyapatite mineralized collagen (HA/Col) scaffolds.
Methods:
A high-molecular-weight polyacrylic acid-stabilized amorphous calcium magnesium strontium phosphate precursor (HPAA/ACMSP) was prepared. Its morphology and elemental distribution were characterized by high-resolution transmission electron microscopy (TEM) and energy-dispersive spectroscopy. Recombinant collagen sponge blocks were immersed in the HPAA/ACMSP mineralization solution. Magnesium-strontium co-doped hydroxyapatite was induced to deposit within collagen fibers (experimental group: MSHA/Col; control group: HA/Col). The morphological characteristics of MSHA/Col were observed using scanning electron microscopy (SEM). Its crystal structure and chemical composition were analyzed by X-ray diffraction and Fourier transform infrared spectroscopy, respectively. The mineral phase content was evaluated by thermogravimetric analysis. The scaffold's porosity, ion release, and in vitro degradation performance were also determined. For cytological experiments, CCK-8 assay, live/dead cell staining, alkaline phosphatase staining, alizarin red S staining, RT-qPCR, and western blotting were used to evaluate the effects of the MSHA/Col scaffold on the proliferation, viability, early osteogenic differentiation activity, late mineralization capacity, and gene and protein expression levels of key osteogenic markers [runt-related transcription factor 2 (Runx2), collagen type Ⅰ (Col-Ⅰ), osteopontin (Opn), and osteocalcin (Ocn)] in mouse embryonic osteoblast precursor cells (MC3T3-E1).
Results:
HPAA/ACMSP appeared as amorphous spherical nanoparticles under TEM, with energy spectrum analysis showing uniform distribution of carbon, oxygen, calcium, phosphorus, magnesium, and strontium elements. SEM results of MSHA/Col indicated successful complete intrafibrillar mineralization. Elemental analysis showed the mass fractions of magnesium and strontium were 0.72% (matching the magnesium content in natural bone) and 2.89%, respectively. X-ray diffraction revealed characteristic peaks of hydroxyapatite crystals (25.86°, 31°-34°). Infrared spectroscopy results showed characteristic absorption peaks for both collagen and hydroxyapatite. Thermogravimetric analysis indicated a mineral phase content of 78.29% in the material. The scaffold porosity was 91.6% ± 1.1%, close to the level of natural bone tissue. Ion release curves demonstrated sustained release behavior for both magnesium and strontium ions. The in vitro degradation rate matched the ingrowth rate of new bone tissue. Cytological experiments showed that MSHA/Col significantly promoted MC3T3-E1 cell proliferation (130% increase in activity at 72 h, P < 0.001). MSHA/Col exhibited excellent efficacy in promoting osteogenic differentiation, significantly upregulating the expression of osteogenesis-related genes and proteins (Runx2, Col-Ⅰ, Opn, Ocn) (P < 0.01).
Conclusion
The MSHA/Col scaffold achieves dual biomimicry of natural bone in both composition and structure, and effectively promotes osteogenic differentiation at the genetic and protein levels, breaking through the functional limitations of pure hydroxyapatite mineralized collagen. This provides a new strategy for the development of functional bone repair materials

Objective To analyze the influence of Helicobacter pylori (Hp) infection on the risk of colorectal adenomatous polyps in patients with type 2 diabetes mellitus (T2DM). Methods A total of 306 patients with T2DM who were treated in the hospital from April 2021 to April 2024 were enrolled as the study subjects. According to whether colorectal adenomatous polyps occurred, the enrolled patients were divided into adenomatous polyp group and non-adenomatous polyp group. The risk factors of colorectal adenomatous polyps in T2DM patients were discussed by univariate and Logistic multivariate regression analyses. The predictive value of Hp on the occurrence of colorectal adenomatous polyps was explored by receiver operating characteristic (ROC) curve. Results Among 306 T2DM patients, there were 142 cases of colorectal adenomatous polyps, with an incidence rate of 46.41%. After logistic analysis, it was found that Hp infection, concurrent gallbladder disease, fatty liver, alcohol drinking history and insulin use were independent influencing factors for colorectal adenomatous polyps (OR: 5.518, 95%CI: 2.806-10.850; OR: 2.782, 95%CI: 1.406-5.502; OR: 3.702, 95%CI: 1.684-8.141; OR: 2.125, 95%CI: 1.140-3.964; OR: 5.398, 95%CI: 2.528-11.525, P<0.05). ROR curve analysis indicated that the area under the curve (AUC), sensitivity and specificity of Hp infection in predicting colorectal adenomatous polyps were 0.611, 38.73% and 83.54%. Conclusion The occurrence of colorectal adenomatous polyps in patients with T2DM is affected by many factors among which Hp infection has obvious predictive value on its risk.

Abnormal synaptic plasticity is an early pathological feature of Alzheimer disease (AD). Synaptic damage and dysfunction initiate neuronal degeneration and death, ultimately leading to cognitive impairment. Traditional Chinese medicine (TCM) can effectively ameliorate cognitive dysfunction through multitarget regulation of synaptic plasticity. This review summarizes the mechanisms by which TCM, including active components, single herbs, and classical formulas, modulates synaptic plasticity, offering new insights for future research and clinical applications. Relevant experimental studies published between 2020 and 2024 were retrieved from major databases, including China National Knowledge Infrastructure, the National Science and Technology Library, Wanfang Data, Elsevier, ScienceDirect, PubMed, SpringerLink, and Web of Science. Network pharmacology and bioinformatics approaches were used to predict the therapeutic effects and mechanisms of TCM on AD-related synaptic plasticity. In total, 15 TCM single herbs and 11 TCM formulas were identified as enhancing AD-related synaptic plasticity. Additionally, 15 active ingredients targeting synaptic plasticity in AD were retrieved from TCM databases over the past decade. This review provides novel perspectives and strategic directions for future AD research and therapeutic development.

Background:
Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA).
Methods:
Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound.
Results:
In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation.
Conclusions
Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.

Objective:To explore the dynamic change trajectory and influencing factors of postoperative fatigue (POF) in patients with early digestive tract cancer undergoing endoscopic submucosal dissection (ESD), so as to provide theoretical basis for individualized management of such patients.Methods:Using cross-sectional survey and convenient sampling method, the patients who underwent ESD for early cancer of digestive tract in the endoscopic center of the Second Affiliated Hospital of Zhejiang University School of Medicine from January to June 2024 were selected as the research objects. The questionnaires were conducted at 30 min, 24 h, 3 days, 5 days, 7 days after ESD with Christensen's postoperative fatigue score. Spearman test was used to analyze the correlation between pain, insomnia and POF. The latent variable growth model was used to identify the potential categories of POF trajectory, and the influencing factors were analyzed by Logistic regression.Results:A total of 232 patients were finally induded, with ages of 19-94(59.53 ± 13.29) years, including 120 males and 112 femalss. The POF level of patients with early cancer of digestive tract showed a downward trend one week after operation. Three postoperative fatigue trajectories were fitted, 9.05% in moderate or severe fatigue low-speed smooth descent group (C1 group); 32.76% in moderate fatigue first decreased quickly and then slowly group (C2 group) and 58.19% in mild fatigue continuous decline group (C3 group). The result of Logistic regression analysis showed that, compared with C1 group, people without religious beliefs were morelikely to enter C2 group [ β = 1.572, OR = 4.818(1.033 - 22.465), P<0.05]; compared with C3 group, patients with high pain level and severe insomnia degree were likely to enter C1 [ β = 2.621, 0.663, OR were 13.754(2.692 - 70.283) and 1.942(1.429 - 2.638), both P<0.05] and C2 [ β = 2.010, 0.491, OR were 7.464(1.890 - 29.482) and 1.634(1.348 - 1.982), both P<0.05] group. Conclusions:There were three potential types of POF in patients with early digestive tract cancer ESD. Medical staff should pay attention to patients with severe insomnia, intense pain and religious beliefs, and give staged fatigue assessment and individualized intervention, so as to reduce the level of POF and promote rapid recovery.
