Gorham-Stout disease(GSD) is a rare osteolytic disorder characterized by spontaneous and progressive osteolysis, along with abnormal angiogenesis and lymphangiogenesis, with no new bone formation. We present a case of a 15-year-old female admitted due to " recurrent right leg pain for 5 years, 11 months after undergoing right femoral fracture surgery". Through comprehensive integration of the patient's clinical phenotype, laboratory tests, imaging findings, pathological examinations, and molecular biological test results, GSD was considered highly likely. A multidisciplinary treatment approach was conducted, including a combination of zoledronic acid and sirolimus to inhibit osteolysis, along with rehabilitation training and orthopedic intervention, providing a personalized and comprehensive treatment strategy.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective To compare the 12-month efficacy and safety of N-butyl cyanoacrylate (NBCA) versus radiofrequency ablation (RFA) in treating great saphenous vein (GSV) insufficiency. Methods A total of 155 patients with GSV insufficiency from five centers were randomly allocated to the NBCA group or RFA group. Postoperative efficacy and safety outcomes were evaluated. Results Immediate postoperative closure rates of the GSV trunk were 100% in both groups. The closure rates of NBCA and RFA group were 98.6% and 98.5% at 3 months, 97.1% and 98.5% at 6 months, 98.1% and 95.9% at 12 months, with no statistically significant differences (P>0.05). After treatment, CEAP classification improved significantly from baseline in both groups. In terms of safety, 1 case of phlebitis, 1 case of ablation-related thrombus extension (ARTE) and 2 cases of calf muscle venous thrombosis(CMVT) occurred in the NBCA group, while 2 cases of limb numbness, 1 case of persistent thigh pain and 2 cases of CMVT in the RFA group. All reported serious adverse events in both groups were assessed as unrelated to the medical device or the trial procedure. Conclusions NBCA demonstrates non-inferior efficacy and safety compared to RFA for treating GSV insufficiency over 12 months.

Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as ¹³¹I,¹⁷⁷Lu, or ¹⁸F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, ¹⁸F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

OBJECTIVES: To fabricate an injectable composite microsphere hydrogel reinforced with silk fibroin/hyaluronic acid microspheres, achieving synergistic enhance-ment of mechanical robustness and biofunctionality. METHODS: Methacrylated hyaluronic acid (HAMA) and thiolated silk fibroin (TSF) were synthesized. Monodisperse microspheres generated via microfluidics were UV-cured (420 nm) through thiol-ene click reaction. These microspheres were embedded in a TSF/HAMA matrix to form photo-cured composites. The grafting rate of TSF and HAMA was characterized by H1-NMR; particle size distribution of microsphere hydrogels in soybean oil was observed by optical microscopy; gel point of composite microsphere hydrogels was determined by advanced extensional rheometer; microscopic morphology of microsphere hydrogels was observed by scanning electron microscopy; elemental distribution of microsphere hydrogels was detected by X-ray energy dispersive spectroscopy; tunability of composite microsphere hydrogels was observed by inverted confocal microscopy; mechanical properties of composite microsphere hydrogels were tested by compression testing; swelling ratio, degradation rate and water retention rate of composite microsphere hydrogels were measured by gravimetric method. Cytotoxicity of the composite microsphere hydrogels was determined by Calcein-AM/propidium iodide dual staining and CCK-8 assay; cell migration capability was observed by scratch assay. RESULTS: The grafting rates of HAMA and TSF was 48.03% and 17.99%, respectively. Microsphere hydrogels with particle sizes of (43.3±1.2), (78.1±3.0), and (130.8±1.9) μm were prepared. The gel time of the composite microsphere hydrogels was 48-115s. The laser confocal imaging confirmed dynamic regulation characteristics of the composite microsphere hydrogels. The compressive strength of the composite microsphere hydrogels reached 22.7 kPa and maintained structural integrity at 40% strain after 20 compression cycles. The composite microsphere hydrogels exhibited differential deswelling behaviors in simulated physiological environments, and reducing microsphere particle size could significantly enhance its stability under moist conditions. The degradation rate of the composite microsphere hydrogels was (49.1±0.9)% after 200 h, and water retention rate was maintained at 40%-60% after 96 h. Biocompatibility assays confirmed >95% cell viability and unimpaired cell migration abilities. CONCLUSIONS The TSF/HAMA composite microsphere hydrogel developed in this study has characteristics of rapid fabrication, adjustable mechanical properties, enhanced environmental stability and excellent biocom-patibility, thus providing a new material solution for tissue repair and regenerative medicine.

This paper summarizes Professor SHI Zaixiang's clinical experience in treating high fever caused by sepsis using Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）. He holds that the key pathogenesis of sepsis involves constrained heat in the shaoyang and internal accumulation of water and fluids. The clinical manifestations such as high fever， chills， and alternating sensations of cold and heat are attributed to pathogenic heat constrained in the shaoyang. Meanwhile， soft tissue edema and serous cavity effusions are due to shaoyang dysfunction and internal water retention. In clinical practice， treating sepsis-related high fever requires addressing both the shaoyang-constrained heat and the associated edema and effusions. The therapeutic approach focuses on harmonizing the shaoyang and resolving internal fluids， using Chaihu Guizhi Ganjiang Decoction as the base formula with flexible modifications. Professor SHI emphasizes that this formula shows a rapid antipyretic effect， particularly in cases where multiple anti-infective treatments have failed.

The pathogenesis of painful diabetic peripheral neuropathy(PDPN)is very complicated and tricky treat,which seriously affects the physical and mental health of patients.TCM has certain advantages in treating PDPN,but lacks theoretical guidance centered on pathogenesis.The dynamic evolution of the pathogenesis of PDPN fits the theory of"deficient-qi induced stagnation".PDPN is mainly characterized by pain,with prolonged pain entering the collaterals.This article discussed the pathogenesis of PDPN from the theory of"deficient-qi induced stagnation"based on collateral disease.Among them,the"deficient qi"is mainly responsible for the deficiency of qi,blood,yin and yang,and the collaterals are not be nourished;"stagnation"includes the pathological state of qi stagnation,phlegm and stasis caused by the abnormal movement of qi,blood and body fluid,and the obstruction of collaterals."Deficient qi"and"stagnation"interact with each other to promote the progress of PDPN.The article concluded that the key point of treatment is to regulate the deficiency qi(tonify deficiency)and remove stagnation and clear collaterals(smooth the stagnation),which could provide a new diagnosis and treatment idea and theoretical basis for the clinical differentiation and treatment of PDPN.

Objective:To investigate the effects of Xuebijing injection on gut microbiota and intestinal mechanical barrier in mice with lipopolysaccharide (LPS)-induced sepsis, and analyze the potential mechanism by which Xuebijing injection protects gastrointestinal tract.Methods:Twenty-four healthy and clean grade male C57BL/6N mice were divided into four groups, control group, LPS group, LPS+ 5 μl/g Xuebijing injection group (5 μl/g Xuebijing injection group), and LPS+ 10 μl/g Xuebijing injection group (10 μl/g Xuebijing injection group), with six mice in each group. A mouse model of sepsis was established by intraperitoneal injection of mice with 10 μg/g LPS. At 0 and 12 h after successful modeling, the mice were intraperitoneally injected with 5 or 10 μl/g Xuebijing injection. Blood, ileum, and colon fecal samples were collected 12 h after the second administration. ELISA was used to detect the levels of diamine oxidase (DAO), D-blood lactic acid (D-Lac), TNF-α, and IL-6. HE staining was used to observe the local ileum damage, and Chiu′s score was used to evaluate the degree of intestinal tissue damage. Immunohistochemical staining and Western blot were used to detect the expression of Claudin-1, Occludin, and zona occludins-1(ZO-1) in ileum tissues, followed by semi quantitative analysis. One-way analysis of variance was used for intergroup comparisons, and LSD or Tamhane′s T2 test was used for pairwise comparisons based on the homogeneity of variance. The diversity and species composition of mouse fecal microbiota, and the differences among groups were analyzed using 16S rRNA sequencing.Results:The levels of DAO, D-Lac, TNF-α, and IL-6 in the LPS group were higher than those in the control group (all P<0.000 1). After the intervention with Xuebijing injection, the levels of DAO, D-Lac, TNF-α, and IL-6 decreased (all P<0.05) and showed no significant differences with those in the control group (all P>0.05). Besides, 10 μl/g Xuebijing injection was more effective than 5 μl/g Xuebijing injection in reducing the concentrations (all P<0.05). Chiu′s score was higher in the LPS group than in the control group and the 10 μl/g Xuebijing injection group (both P<0.05). Western blot showed that the expression levels of Occludin, Claudin-1, and ZO-1 in the LPS group were lower than those in the control group (all P<0.01), and Xuebijing injection intervention significantly increased the expression levels of these proteins in a dose-dependent manner as compared with the LPS group (all P<0.000 1). Apart from the expression level of ZO-1, which showed no significant difference between the two Xuebijing injection groups ( P>0.05), the results of immunohistochemical staining were consistent with those of Western blot. The 16S rRNA sequencing results showed that there were differences in the Alpha and Beta diversity indices, and the composition and structure of gut microbiota among the four groups. The structure of gut microbiota in the mice treated with Xuebijing injection was similar to that in the mice of the control group and it was in a dose-dependent manner. Wilcoxon rank sum test showed that there were statistically significant differences in six gut microbiota groups at the phylum level, and 32 gut microbiota groups at the genus level among the mice of four groups (all P<0.05). Conclusions:Xuebijing injection can provide protective effects on the gastrointestinal tract by protecting the structure of gut microbiota and intestinal barrier function, and the protective effect is somewhat correlated with the drug dosage.
