Objective:
To fabricate a hydrogel loaded with inositol hexaphosphate-zinc and preliminarily evaluate its performance in self-mineralization and osteoinduction, thereby providing a theoretical basis for the development of bone regeneration materials.
Methods:
The hydrogel framework (designated DF0) was formed by copolymerizing methacryloyloxyethyltrimethylammonium chloride and four-armed poly(ethylene glycol) acrylate, followed by sequentially loading inositol hexaphosphate anions via electrostatic interaction and zinc ions via chelation. The hydrogel loaded only with inositol hexaphosphate anions was named DF1, while the co-loaded hydrogel was named DF2. The self-mineralization efficacy of the DF0 , DF1 and DF2 hydrogels was characterized using scanning electron microscopy, transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and selected area electron diffraction (SAED). The biocompatibility was assessed via live/dead cell staining and a CCK-8 assay. The osteoinductive capacity of the DF0 , DF1 and DF2 hydrogels on MC3T3-E1 cells was assessed via alkaline phosphatase (ALP) and Alizarin Red S (ARS) staining. In the aforementioned cell experiments, cells cultured in standard medium served as the control group
Results:
The DF0, DF1, and DF2 hydrogels were successfully synthesized. Notably, DF1 and DF2 exhibited distinct self-mineralization within 6 days. Results from TEM, EDS, and SAED confirmed that the mineralization products were amorphous calcium phosphate in group DF1, and amorphous calciumzinc phosphate in group DF2. Biocompatibility tests revealed that none of the hydrogels (DF0, DF1, and DF2) adversely affected cell viability or proliferation. In osteogenic induction experiments, both ALP and ARS staining were intensified in the DF1 and DF2 groups, with the most profound staining observed in the DF2 group.
Conclusion
The developed inositol hexaphosphate-zinc hydrogel (DF2) demonstrates the dual capacity to generate calcium-phosphate compounds through self-mineralization while exhibiting excellent osteoinductive properties. This biocompatible, dual-promoting osteogenic hydrogel presents a novel strategy for bone regeneration.
2.New advances in the study of the etiology and treatment of floaters
International Eye Science 2025;25(3):446-450
As a common ophthalmic disease, floaters have a complex etiology. It involves changes in the structure and function of the vitreous body and is closely associated with factors like age and myopia. Vitreous liquefaction and posterior detachment play a crucial role in this regard. Clinically, patients usually experience the floating of dotted or linear black shadows in front of their eyes, and generally, floaters do not cause visual impairment. In the past, due to the limitations of traditional concepts and treatment methods, a conservative observation strategy was often adopted. However, an increasing number of patients have complained that floaters lead to difficulties in driving and reading, which seriously affects their visual quality and mental health. Consequently, the demand for treatment has been growing day by day. The existing treatment options each have their own advantages and disadvantages. The efficacy of drug treatment is limited and remains controversial. Vitrectomy has a definite curative effect, yet it comes with a high risk of complications. YAG laser vitreolysis is relatively safe, but its curative effect is restricted by factors such as the size and location of the opacities. Nanobubble-mediated vitreolysis is still in the research stage and is expected to offer patients safer and more effective treatment in the future. This article reviews the etiology of floaters and the latest progress in its treatment, aiming to deepen clinicians' understanding of floaters, provide a more comprehensive scientific basis for clinical diagnosis and treatment, and promote personalized and precise treatment.

It is believed that patients with cirrhotic ascites exhibit a pathological mechanism characterized by the decline of healthy qi and the accumulation of pathogenic factors. Clinically, treatment should be based on the theory of tonification and purging, with a staged approach distinguishing between the active phase and the remission phase. The balance between tonification and purging should be adjusted according to the progression of pathogenic and healthy actors. In the acute phase, purging should take precedence over tonification, using purging as a means of tonification to facilitate the flow of water and qi through the triple energizer. The severity of water retention, dampness, blood stasis, and heat should be carefully assessed to ensure thorough elimination of pathogenic factors while avoiding harm to healthy qi. Medication adjustments should be made once the pathogenic factors are significantly weakened. In the remission phase, an integrated approach combining both tonification and purging should be adopted, incorporating purging within tonification to clear residual pathogens and prevent recurrence. Concurrently, proactive treatment of the underlying disease is essential to achieve complete recovery and prevent the recurrence of ascites.

[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

From the perspective of "kidney-heart-meridians", this paper explores the pathogenesis and treatment strategies for sick sinus syndrome (SSS). The author proposes that the root cause lies in kidney essence deficiency and failure of source qi generation. The key pathogenic mechanisms include qi sinking with cold generation and constrained heart yang. The chronic progression is attributed to impaired transformation of body fluids and blood, leading to stagnation and obstruction of the meridians. Phlegm retention and blood stasis obstructing the heart meridians are considered major factors in disease aggravation. Accordingly, the core treatment principles are to nourish the kidneys and restore source qi, tonify the heart and regulate the meridians. Supplementing qi, lifting sinking, soothing constraint, and promoting yang are employed to halt disease progression, while warming and enriching body fluids and blood aim to harmonize and unblock the meridians to improve prognosis. Strategies such as resolving phlegm, relieving obstruction, activating blood, and dispersing nodules are applied to prevent deterioration. This provides a reference framework for the clinical management of SSS.

Under the background of the Healthy China strategy, the integration of traditional Chinese medicine (TCM) into the public health emergency response system has become an important measure to enhance the capacity for coping with public health emergencies. In recent years, the role of TCM in responding to such emergencies has become increasingly prominent. Taking major emerging epidemics as an example, TCM has developed a rich theoretical system and practical experience in epidemic prevention and treatment over thousands of years, and has played a significant role in successive outbreaks with its unique advantages. Based on the concept of ''preventing disease before its onset'' and the theoretical framework of treatment based on syndrome differentiation, TCM has achieved remarkable results through early intervention and full participation in the integrated model of TCM and Western medicine, from severe acute respiratory syndrome (SARS) to corona virus disease-2019 (COVID-19), in improving clinical symptoms and outcomes, reducing adverse reactions, and promoting recovery. From the perspective of the Healthy China strategy, this paper systematically reviews the historical development of TCM in epidemic prevention and treatment, with particular attention to recent epidemics such as SARS, influenza A (H1N1), and COVID-19. It further examines the similarities and differences between TCM and Western medicine in responding to major emerging epidemics, as well as relevant policies related to TCM in epidemic prevention and control. In addition, it summarizes the existing problems in TCM's role in the prevention and treatment of major emerging epidemics, and explores measures to improve its rapid response capacity under the Healthy China strategy. This study not only provides a ''Chinese solution'' for the prevention and control of newly emerging infectious diseases worldwide, but also offers theoretical and practical references for strengthening the public health emergency response system, carrying strategic significance for promoting the modernization and internationalization of TCM.

Ulcerative colitis (UC), a chronic, non-specific inflammatory bowel disease with typical symptoms such as abdominal pain, diarrhea, and bloody stools, demonstrates a high relapse rate and difficulty in curing. Sishenwan, first recorded in Internal Medicine Abstract (Nei Ke Zhai Yao), are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney, and astringing the intestine and stopping diarrhea. In recent years, Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors, including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term, its side effects, high relapse rate, and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan, used alone or in combination with Western medicine or other Chinese medicine compound prescriptions, significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus, pus, and blood in stools, and persistent abdominal pain, reduce Mayo scores and the relapse rate, and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen, isopsoralen, and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level, Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future, a full-chain system covering syndrome differentiation, targeting, and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics, providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

Tuberculosis (TB) is a chronic infectious disease caused by Mycobacterium tuberculosis, which is primarily transmitted through the respiratory tract, and remains one of the diseases with the highest mortality rate of single-pathogen infections globally. The cell wall polysaccharides of M. tuberculosis are critical for maintaining bacterial structure, mediating pathogenesis, and enabling immune evasion. Lipoarabinomannan (LAM), a key polysaccharide component, has revolutionized non-invasive diagnostic technologies as a TB biomarker, while polysaccharide-based vaccines have emerged as innovative strategies for TB prevention. This review systematically examines the composition, subcellular distribution, and functional roles of M. tuberculosis cell wall polysaccharides in bacterial metabolism, drug resistance, and immune regulation. A particular emphasis is placed on recent advancements in LAM-based diagnostics and vaccine development. Future studies should utilize advanced technologies to precisely characterize the structural features of TB polysaccharides and explore their biological functions, providing a foundation for targeted diagnostic and therapeutic innovations. This article aims to provide reference for advancing both basic research and clinical applications related to M. tuberculosis.
