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.

Objective:
To observed the effect of a curcumin-based vaginal gel combined with electroporation for the treatment of vulvovaginal candidiasis (VVC) caused by Candida albicans.
Methods:
Temperature-sensitive in situ gels (ISG) were prepared using poloxamers 407 and 188 as matrices. The mass ratio of poloxamer 407 and poloxamer 188 was 7:1 with a gelation temperature of approximately 29°C and gelation time of 2.5 min.
Results:
Electroporation increased the transmucosal permeability of the model drug, doxorubicin and improved the antifungal effects of curcumin. In vitro antifungal experiments showed that the number of fungal colonies in curcumin ISG combined with electroporation was lower than that in pure curcumin ISG. In vivo pharmacodynamic experiments showed that, compared to the model group, curcumin ISG with electroporation inhibited the growth of C. albicans, alleviated vaginal mucosal edema, and reduced the inflammatory response.
Conclusion
Curcumin ISG combined with electroporation has substantial potential for the efficient clinical treatment of VVC.

Objective:To analyze the incidence and mortality of pancreatic cancer in China from 1992 to 2021, and to explore the effects of age, period, and cohort on pancreatic cancer incidence and mortality.Methods:Data from the Global Burden of Disease Study (GBD) 2021 database were used to analyze the incidence and mortality of pancreatic cancer in China from 1992 to 2021. The Joinpoint software was applied to analyze the time trends of standardized incidence and mortality rates, and to calculate the average annual percentage change. An age-period-cohort model was constructed to analyze the effects of age, period, and birth cohort on the trends of pancreatic cancer incidence and mortality. The disease burden of pancreatic cancer deaths attributed to risk factors such as hyperglycemia and smoking was analyzed.Results:In 2021, the incidence of pancreatic cancer in China was 8.34/100 000, and the mortality rate was 8.41/100 000, representing increases of 150.45% and 145.19%, respectively, compared to 1992 (3.33/100 000 and 3.43/100 000) . By sex, the incidence (9.93/100 000) and mortality (9.91/100 000) rates in males in 2021 were higher than those in females (6.68/100 000 and 6.83/100 000) . From 1992 to 2021, the standardized incidence and mortality rates of pancreatic cancer in China showed upward trends, with average annual increases of 0.80% and 0.62%, respectively, both of which were statistically significant (both P<0.001) . Age effect results indicated a general increasing trend in pancreatic cancer incidence, with a steady rise in the 15-49 age group, a sharp increase after the age of 50, and a peak in the over 85 age group at 68.64/100 000. The mortality rate showed a slow increase in the 15-79 age group, with a marked rise and peak in the 80-84 age group at 196.51/100 000. Period effect results showed an overall upward trend in the period relative risk ( RR) for pancreatic cancer incidence, with the highest risk in 2017-2021 ( RR=1.09, 95% CI: 1.05-1.13, P=0.012) , compared to the reference period 2002-2006 ( RR=1) . The RR for pancreatic cancer mortality showed a fluctuating trend, with the highest risk in 2012-2016 ( RR=1.60, 95% CI: 1.07-2.38, P=0.021) , compared to the reference period 2002-2006 ( RR=1) . The results of cohort effect showed that the incidence and mortality risk of pancreatic cancer in China generally increased with the increase of years. With the 1952-1956 birth cohort as the reference cohort ( RR=1) , the incidence ( RR=1.18, 95% CI: 0.99-1.40, P=0.032) and mortality ( RR=1.63, 95% CI: 0.12-11.53, P=0.042) risk of pancreatic cancer were the highest in the 1987-1991 birth cohort, and showed decreasing trends after the 1992-1996 birth cohort. The proportion of pancreatic cancer deaths attributable to high blood glucose showed an increasing trend, while those attributable to smoking showed a decreasing trend. Conclusions:From 1992 to 2021, the standardized incidence and mortality rates of pancreatic cancer in China have continued to rise, with males having higher incidence and mortality rates than females. Age, period, and cohort all significantly influence the trends in pancreatic cancer incidence and mortality. The trend in pancreatic cancer deaths attributable to high blood glucose is increasing.
