ObjectiveTo observe the effect of Huayu Mingmu prescription on retinal angiogenesis and phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）-hypoxia inducible factor-1α/vascular endothelial growth factor A （HIF-1α/VEGFA） signaling pathway in diabetic retinopathy （DR） rats. MethodsSixty-four SPF-grade male SD rats were used in the study. Eleven rats were randomly selected as the normal group， while the remaining 53 rats were fed a high-sugar， high-fat diet combined with low-dose streptozotocin （STZ） intraperitoneal injection to establish a type 2 diabetes mellitus （T2DM） rat model. DR model evaluation was performed after 12 weeks of diabetes. The rats were then divided into model， low-dose， medium-dose， and high-dose groups of Huayu Mingmu prescription （9.29， 18.57， 37.14 g·kg^-1）， and a calcium dobesilate group （0.16 g·kg^-1）， with 10 rats in each group. The rats were orally administered the corresponding doses of Huayu Mingmu prescription and calcium dobesilate. The normal and model groups received equal volumes of physiological saline via gavage for 8 consecutive weeks. Retinal vascular changes were observed through fundus photography， and pathological changes in retinal tissue were evaluated using hematoxylin-eosin （HE） staining. Retinal microvascular pathological changes were examined through retinal vascular network preparation and periodic acid-Schiff （PAS） staining. Immunofluorescence （IF） was used to detect the expression of VEGFA and angiopoietin-2 （Ang-2） in retinal tissue. Western blot was employed to detect the protein expression of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to assess the mRNA expression of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue. ResultsCompared with the normal group， the model group exhibited significant pathological changes in retinal tissue， including the appearance of acellular capillaries， as well as significant endothelial cell （E） proliferation and pericyte （P） loss （P<0.01）. The E/P was significantly elevated （P<0.01）. Protein and mRNA expression levels of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue were significantly increased （P<0.01）， and the expression of Ang-2 protein was significantly elevated （P<0.01）. In contrast， retinal tissue in the treatment groups showed alleviated pathological changes， with reduced endothelial cell proliferation and pericyte loss （P<0.05， P<0.01）. Among the treatment groups， the high-dose Huayu Mingmu prescription and the calcium dobesilate group exhibited a decreased E/P （P<0.01）. Protein and mRNA expression levels of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue were significantly reduced （P<0.05， P<0.01）， and the expression of Ang-2 protein was significantly decreased （P<0.01）. ConclusionHuayu Mingmu prescription can intervene in retinal neovascularization in DR rats， delay the progression of DR， and its mechanism may be related to antagonizing the PI3K/Akt/mTOR-HIF-1α/VEGFA signaling pathway.

Background::Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.Methods::This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied.Results::At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs. placebo, 95% CI 31%–69%) and 45% (low vs. placebo, 95% CI 26%–64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator’s Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310. Conclusion::CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.Trial Registration::ClinicalTrials.gov, NCT04805411.

Objective To explore the predictive value of novel anthropometric indicators for the long-term prognosis in patients with acute myocardial infarction(AMI).Methods A total of 712 patients diagnosed with AMI in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2019 were selected as research subjects,and divided into an event group and a non-event group according to whether major cardiovascular adverse events(MACEs)occurred during the period of follow-up.Gensini score was used to quanti-tatively assess the degree of coronary artery stenosis.Spearman correlation analysis was used to explore the correla-tion between the new anthropometric indicators and Gensini score.Receiver operating characteristic(ROC)curve was used to evaluate the ability of new anthropometric indicators to predict MACEs,and the patients were grouped according to the optimal cut-off value.Kaplan-Meier curve was used to analyze the survival difference between the groups.Multivariate Cox regression was used to analyze the independent risk factors of MACEs.Results During a median follow-up of 27(20,39)months,a total of 125 patients developed MACEs.As compared with those in the non-event group,the patients in the event group had a higher proportion of hypertension,diabetes and abdominal obesity,higher HbA1c and FBG levels,and longer body weight and waist circumference.The LAP index,CMI index,BRI index and Gensini score were significantly increased,and the differences were statistically significant(P＜0.05).Spearman correlation analysis showed that LAP index,CMI index and BRI index were positively corre-lated with Gensini score(r=0.233,0.126,0.272,P<0.001).ROC curve analysis showed that the AUC of LAP index,CMI index,VAI index,BRI index and ABSI index were 0.745,0.640,0.490,0.874 and 0.506 respec-tively;Kaplan-Meier curve analysis showed that the cumulative incidence of MACEs in LAP index,CMI index and BRI index was significantly increased in the high-value group(Log-rank test,P＜0.05).The results of multivariate Cox regression analysis after adjusting confounding showed that CMI index(HR=1.430,95%CI:1.049～1.952,P=0.024)and BRI index(HR=1.332,95%CI:1.234～1.439,P＜0.001)were independent risk factors for MACEs.Conclusions CMI index and BRI index of new anthropometric indicators are independent risk factors for long-term prognosis in patients with AMI.

Clinical practice guideline adaptation (hereinafter referred to as "guideline adaptation") is the consolidation and revision of existing high-quality guidelines so that the recommendations are better suited to the specific needs of different regions, thereby guiding optimal clinical practice. Currently, the guideline adaptations is increasing in number internationally, but their reporting quality still needs to be improved. In 2022, the RIGHT-Ad@pt guideline adaptation reporting checklist was released. It provides a detailed description of the guideline adaptation process and reporting content, which will significantly enhance the rigor, transparency, and standardization of guideline adaptations. This paper interprets and analyzes the 34 items on the checklist, with the aim of providing reference for guideline adapters to standardize the reporting process.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the correlation between cardiometabolic index(CMI) and the severity of coronary artery stenosis and long-term prognosis in patients with acute myocardial infarction(AMI).Methods:A total of 712 patients with AMI who were admitted to the Xinjiang Uygur Autonomous Region People′s Hospital from January 2018 to December 2019 were included as the subjects. According to the tertile of CMI, the subjects were divided into high, medium, and low value groups. Gensini score was used to quantitatively assess the degree of coronary artery stenosis. The endpoint event was defined as the occurrence of major cardiovascular adverse events(MACEs). Spearman correlation analysis was conduceted to explore the correlation between CMI and Gensini score. Multivariate Cox regression was utilized to analyze the independent influencing factors of MACEs. A restricted cubic spline plot was employed to analyze the nonlinear relationship between CMI and the risk of MACEs. Kaplan- Meier curve was used to analyze survival differences between groups. Subgroup analysis was performed to evaluate the consistency of the predictive value of CMI for MACEs. Results:Spearman correlation analysis showed that CMI was positively correlated with Gensini score( r=0.13, P<0.001). After adjusting for confounding, multivariate Cox regression analysis showed that CMI was an independent risk factor for MACEs( HR=1.709, 95% CI 1.052-2.778, P=0.031). The restricted cubic spline analysis revealed an L-shaped nonlinear effect relationship between CMI and MACEs risk( P=0.024). Kaplan- Meier survival curve analysis demonstrated that the cumulative incidence of MACEs in AMI patients increased significantly with the increase of CMI( P<0.05). Subgroup analysis indicated that CMI independently predicted the occurrence of MACEs across different subgroups, and had higher predictive value in patients with normal lipids and normal body weight. Conclusion:CMI is closely associated with the severity of coronary stenosis in AMI patients, and is an independent predictor of the risk of long-term MACEs.

ObjectiveTo analyze the characteristics of plantar pressure of diabetic patients during gait cycle, and to design a offloading insole with variable stiffness. MethodsThe plantar pressure experiment was carried out and a database including 157 subjects was established. The differences of plantar pressure distribution were analyzed among diabetic patients with and without peripheral neuropathy, and healthy people. The insole pressure area was divided, and porous units were filled in different insole areas according to the pressure gradient. The fed-calf-insole finite element model of diabetic patients was constructed. The simulation analysis of different insole schemes was carried out under the conditions of push-off, footheel-strike and dynamic neutrality posture, and to explore the most reasonable insole stiffness design. ResultsCompared with the healthy group, the percentage of peak pressure and high pressure in the left and right heel areas of diabetic neuropathy patients showed a decreasing trend, in which the left peak pressure was significantly reduced by 11% (P = 0.026) and the percentage of high pressure was significantly reduced by 9.8% (P = 0.02). When the porous elements of 2.5 MPa and 1.9 MPa were used in the high pressure area of the insole metatarsal and high pressure area of the heel, the peak plantar pressure of footheel-strike, dynamic neutral and push-off was reduced by 42.4%, 27.4% and 26.4%, and the peak stress of the soft tissue was reduced by 49.8%, 43.6% and 25.1%, respectively. ConclusionThere is a higher risk of ulcer in the metatarsal region than in the heel region for diabetic patients. The variable stiffness insoles based on the optimization of plantar pressure and internal stress under multi-posture can effectively reduce the peak pressure of plantar and peak stress of soft tissue during walking, which provides a reference for the design of variable stiffness insoles.

With the gradual maturity of sequencing technology, many microbiome studies have published, driving the emergence and advance of related analysis tools. R language is the widely used platform for microbiome data analysis for powerful functions. However, tens of thousands of R packages and numerous similar analysis tools have brought major challenges for many researchers to explore microbiome data. How to choose suitable, efficient, convenient, and easy-to-learn tools from the numerous R packages has become a problem for many microbiome researchers. We have organized 324 common R packages for microbiome analysis and classified them according to application categories (diversity, difference, biomarker, correlation and network, functional prediction, and others), which could help researchers quickly find relevant R packages for microbiome analysis. Furthermore, we systematically sorted the integrated R packages (phyloseq, microbiome, MicrobiomeAnalystR, Animalcules, microeco, and amplicon) for microbiome analysis, and summarized the advantages and limitations, which will help researchers choose the appropriate tools. Finally, we thoroughly reviewed the R packages for microbiome analysis, summarized most of the common analysis content in the microbiome, and formed the most suitable pipeline for microbiome analysis. This paper is accompanied by hundreds of examples with 10,000 lines codes in GitHub, which can help beginners to learn, also help analysts compare and test different tools. This paper systematically sorts the application of R in microbiome, providing an important theoretical basis and practical reference for the development of better microbiome tools in the future. All the code is available at GitHub github.com/taowenmicro/EasyMicrobiomeR.

Objective An X-shaped cushioning insole with variable stiffness was designed to explore its effects on plantar pressure and internal stress of diabetic patients with toe amputation. Methods Based on CT images, the feet-calf finite element model of diabetic patients with toe amputation was established, and the insole was divided into different areas according to distribution characteristics of the planter pressure. The three-dimensional (3D) printed cushioning insole with an X-shaped sandwich structure was designed. The modulus of the sandwichstructure was changed by changing thickness of the sandwich structure panel. For simulation analysis, the divided area was filled with the X-shaped sandwich structure with different modulus. Results The peak plantar pressure of diabetic patients with toe amputation was in calcaneal region, and the combined insoles with 1. 2 mpanel thickness in toe area, 1. 4 mm panel thickness in metatarsal area, 2. 0 mm panel thickness in middle area and 1. 6 mm panel thickness in heel area had the best decompression effect. Compared with bare feet, the peak pressure in heel area of the insole, the peak pressure in phalangeal head area and the stress in plantar softissues were reduced by 40. 18% , 31. 7% , and 50. 44% , respectively. Conclusions The 3D printed insoles with variable stiffness can effectively reduce surface pressure and internal stress of the sole and reduce probability of the 2nd toe amputation

Surgical resection in patients with advanced primary carcinoma of liver has high risks of early recurrence and incidence of portal vein tumor thrombus, caused by insufficient resi-dual liver volume after two-steps hepatotomy. At present, the treatment for patients with advanced primary carcinoma of liver is limited, thus can't satisfy the requirement of patient for treatment. The authors introduce the clinical experience of a patient with hepatocellular carcinoma and insufficient residual liver volume who underwent preventive immunotherapy plus target therapy after associa-ting liver partition and portal vein ligation for staged hepatectomy, in order to provide reference for relevant treatment.
