OBJECTIVE To comprehensively evaluate the efficacy， safety and cost-effectiveness of insulin icodec in treating type 2 diabetes mellitus （T2DM）， providing evidence-based guidance for new drug selection in hospital and clinical medication decision-making. METHODS PubMed， Cochrane Library， Embase， CNKI， Wanfang， VIP and foreign health technology assessment （HTA） websites were searched by using rapid health technology assessment from inception to 15 July 2025 for systematic reviews/meta-analyses， pharmacoeconomic studies， and HTA reports on insulin icodec in the treatment of T2DM. After data extraction and quality assessment， the findings of the included studies were analyzed descriptively. RESULTS Ten systematic reviews/meta-analyses and three pharmacoeconomic studies were included. Among them， 4 systematic reviews/meta-analyses were of high quality； the overall quality of the 3 pharmacoeconomic studies was relatively good. Regarding efficacy， insulin icodec was superior to once-daily basal insulin in reducing glycated hemoglobin （HbA1c） and in achieving the target of HbA1c＜7% （P＜0.05）. No significant differences were observed between icodec insulin and comparators in lowering fasting plasma glucose （P＞0.05）. For safety， insulin icodec did not increase the incidence of any adverse events （AEs）， serious AEs， clinically significant hypoglycemia （random glucose＜3 mmol/L）， injection-site reactions， or allergic reactions， compared with once-daily basal insulin overall （P＞ 0.05）； however， insulin icodec was associated with a significant increase in body weight （P＜0.05）. Domestic economic evaluations indicated that insulin icodec was more cost-effective than insulin glargine and insulin degludec when its annual costs were in the range of 784.90-1 145.96 and 597.66-736.34 US dollars， respectively. CONCLUSIONS Insulin icodec demonstrates favorable efficacy and safety profiles in the treatment of T2DM； however， attention should be paid to the risk of weight gain. Under China’s healthcare system， insulin icodec demonstrates greater economic value only when the patient’s weekly required basal insulin dose falls within a specific range，and clinical practice requires individualization.

Disrupted bone morphogenetic protein type 2 receptor (BMPR2) signaling in endothelial cells drives pulmonary arterial hypertension (PAH). However, targeted recovery of this signaling pathway by lipid nanoparticles (LNPs) has not been explored as a therapy. Here, we employed Design of Experiments to optimize the delivery efficiency of LNPs targeting pulmonary endothelial cells developed by our laboratory, resulting in a remarkable 35-fold increase in a simplified three-component formulation without helper lipids. Administration of BMPR2 mRNA LNPs effectively reversed established PAH in two experimental rat models (monocrotaline or SU5416-hypoxia) by reversing pulmonary vascular remodeling. Specifically, BMPR2 mRNA LNPs replenished the expression of BMPR2 protein and subsequently activated downstream pathways, as confirmed by elevated levels of p-SMAD1/5/9 and ID1 proteins. The relief of pulmonary arterial occlusion was demonstrated by thinned pulmonary arterial media and decreased proportion of full muscularized vessels. Alleviation of right ventricular hypertrophy was indicated by declined Fulton index, the cross-sectional area of right ventricular cardiomyocytes as well as collagen deposition. Effective recovery of right ventricular function was evidenced by increased pulmonary artery flow acceleration time/pulmonary artery flow ejection time ratio. These findings underscore the potential of restoring BMPR2 signaling through pulmonary endothelial cell-specific LNPs for treating PAH.

Objective:To explore the feasibility and application value of indocyanine green(ICG)lymph node tracer in clinical early stage cervical cancer staging surgery.Methods:A retrospective analysis was performed on 31 patients with early clinical stage(ⅠA1-ⅡA1)cervical cancer who underwent laparoscopic radical hysterectomy,pelvic lymph node resection and para-aortic lymph node sampling were selected as the study subjects in Sichuan Provincial Maternal and Child Health Care Hospital from April 1,2022 to July 31,2023.They were divided into the ICG fluorescence tracer group(ICG group,17 cases)and the conventional surgery group(control group,14 ca-ses)based on whether ICG was injected or not.The resected lymph nodes were classified and submitted for ex-amination according to location and whether they presented visualization.The method of contingency coefficient was used to analyze the correlations between lymph node visualization patterns and lymph node metastasis and clinicopathological characteristics,and the perioperative data of the two groups were compared.Results:①The postoperative stage of 8 patients(25.8％)(4 in each group)were improved compared with the preoperative clini-cal stage.The number of resected lymph nodes in the ICG group was less than that in the control group(18±9 nodes/person vs.26±11 nodes/person,P＜0.05).There were no statistically significant differences in operation time,intraoperative blood loss,postoperative FIGO(2018)staging,lymph node metastasis rate,and positive rate of resected lymph nodes between the two groups(P＞0.05).②The visualization rate in the ICG group was 64.71％(11/17).There was no statistically significant difference in the positive rate between the visualized and non-visualized lymph nodes(P＞0.05).There was a significant correlation between lymph node visualization and lymph node metastasis(C=0.707,P＜0.05),and a significant correlation was found between lymph node visual-ization and lymph node metastasis in the same patient(C=0.557,P＜0.05).Conclusions:The rate of lymph node metastasis in clinical early stage cervical cancer is low.ICG fluorescence visualization can trace lymph nodes and predict the risk of metastasis.By only resecting the visualized lymph nodes under the guidance of ICG tracer,the lymph node metastasis status of early-stage cervical cancer can be fully evaluated,which is worthy of further research.

Objective:To investigate associations between cardiac biomarkers with stroke severity and short-term outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Qingdao University from June 2018 to February 2024 whose etiological classification was large artery atherosclerosis (LAA), small vessel occlusion (SVO) or cardioembolism (CE) were included retrospectively. According to the National Institutes of Health Stroke Scale score at admission, patients were divided into mild stroke group (≤8) and moderate to severe stroke group (>8). According to the modified Rankin Scale score at discharge, patients were divided into good outcome group (≤2) and poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent correlation between cardiac biomarkers and short-term outcome. The predictive value of cardiac biomarkers for poor outcome in patients with AIS and different stroke etiology subtypes were evaluated using receiver operating characteristic (ROC) curves. Results:A total of 2 151 patients with AIS were enrolled, including 1 256 males (58.4%), aged 67.40±11.34 years. 1 079 patents were LAA type (50.2%), 679 were SVO type (31.6%), and 393 were CE type (18.3%); 1 223 were mild stroke (56.86%) and 928 (43.14%) were moderate to severe stroke; 1 357 patients (63.09%) had good short-term outcome, and 794 (36.91%) had poor short-term outcome. Multivariate logistic regression analysis showed that N-terminal pro-B type natriuretic peptide (NT-proBNP), NT-proBNP/creatine kinase (CK) isoenzyme MB (CK-MB) ratio, and CK-MB/CK ratio were independent risk factors for poor short-term outcome. ROC curve analysis shows that the CK-MB/CK ratio had a higher predictive value for short-term poor outcome in patients with AIS (the area under the curve, 0.859, 95% confidence interval 0.839-0.879). Various cardiac biomarkers had a higher predictive value for short-term outcome of CE type and LAA type, but the predictive value for short-term outcome of SVO type was lower. Conclusions:Cardiac biomarkers are associated with the severity and poor outcome of AIS. NT-proBNP/CK-MB and CK-MB/CK ratios have higher predictive value for short-term poor outcome of AIS, especially in patients with CE type.

BACKGROUND:Acupotomy is an effective method for the clinical treatment of osteoarthritis,with affirmed clinical outcomes,but the specific mechanisms remain unclear OBJECTIVE:To investigate the role of acupotomy in modulating chondrocyte autophagy to promote chondrocyte homeostasis in osteoarthritis. METHODS:Twenty-eight New Zealand rabbits were randomly divided into control group,osteoarthritis group,acupotomy group,and hyaluronic acid group,with seven rabbits in each group.The knee osteoarthritis rabbit model was prepared using the Videman method in the latter three groups.After modeling,the control group and osteoarthritis group received no interventions.The acupotomy group received acupotomy treatment 15 minutes per time,once a week,while the hyaluronic acid group received intra-articular injection of hyaluronic acid once a week,with a continuous treatment duration of 5 weeks.The day after the final intervention,knee joint macrostructure was observed using DR imaging,chondrocyte ultrastructure was examined through transmission electron microscopy,apoptosis of chondrocytes was assessed using Tunel staining,and western blot analysis was used to detect the expression of proteins related to the PI3K/Akt/mTOR pathway. RESULTS AND CONCLUSION:The DR imaging results revealed that the osteoarthritis group exhibited narrowed knee joint spaces and the formation of periarticular osteophytes,while the hyaluronic acid group and acupotomy group showed widened knee joint spaces with a reduction in periarticular osteophytes.Transmission electron microscopy results demonstrated a decreased number of autophagosomes in chondrocytes in the osteoarthritis group,along with nuclear shrinkage,nuclear membrane rupture,incomplete organelle morphology,and a clear tendency towards cell death.In contrast,both the hyaluronic acid group and acupotomy group exhibited a significant increase in autophagosomes,intact nuclear membranes,and a well-preserved cellular state.Tunel staining results indicated a considerable decrease in the number of apoptotic cells in the hyaluronic acid group and acupotomy group compared with the osteoarthritis group.Western blot results revealed that,compared with the control group,the expression levels of Beclin1,Cath D,and LC3II/LC3I were significantly decreased in the osteoarthritis group(P<0.05),while the expression levels of p-Akt/Akt and p-mTOR/mTOR were significantly increased(P<0.05);compared with the osteoarthritis group,the expression levels of Beclin1,Cath D,and LC3II/LC3I were significantly increased in both the hyaluronic acid group and acupotomy group(P<0.05),while the expression levels of p-Akt/Akt and p-mTOR/mTOR were significantly decreased(P<0.05).To conclude,acupotomy intervention can modulate the PI3K/Akt/mTOR signaling pathway to enhance the autophagic level in chondrocytes,thereby maintaining chondrocyte homeostasis.This ultimately leads to a slowdown in cartilage degeneration.

Objective:To explore the clinical characteristics and outcomes of type 2 autoimmune pancreatitis (AIP) and compare with type 1 AIP.Methods:Clinical data of the patients diagnosed with type 2 AIP by the International Consensus on diagnostic criteria of AIP at Peking Union Medical College Hospital from January 2001 to December 2022 were retrospectively analyzed, and type 1 AIP patients diagnosed in Peking Union Medical College Hospital from January 1985 to December 2016 were collected as controls. The clinical symptoms, treatments and follow-ups were analyzed.Results:A total of 25 patients with type 2 AIP were included, of which 16 cases (64.0%) were pathologically confirmed cases (13 cases by endoscopic ultrasound puncture, 2 cases by surgery, and 1 case by interventional puncture), and 9 cases (36.0%) were suspected. The average age of onset was 40 years old. Most patients ( n=23, 92.0%) had abdominal pain along with emaciation to a various degree. Among them, 3 cases primarily presented as acute pancreatitis. Two cases were diagnosed after surgery for pancreatic masses. Eighteen cases were complicated with inflammatory bowel disease, including 16 cases with ulcerative colitis, one case with Crohn's disease, and one case with indeterminate colitis. All patients had typical imaging manifestations, including 13 cases (52.0%) with diffuse pancreatic enlargement, 12 cases (48.0%) with focal or multifocal pancreatic lesions, and 5 cases (20.0%) with simultaneous focal pancreatic masses and diffuse enlargement. All patients had normal serum IgG4 levels, anti-neutropil cytoplasmic antibodies (ANCA) positivity rate was 35.3% (6/17), and anti-nuclear antibody (ANA) positivity rate was 29.2% (7/24). Two surgical patients recovered well after surgery, and the other patients all achieved clinical and imaging relief after hormone therapy, and no recurrence was seen during follow-up. Compared with type 1 AIP, type 2 AIP had younger onset age, main manifestation as abdominal pain without jaundice, rare involvement with extra-pancreatic organs, the lesions mainly located in the intestine and normal IgG4 level with statistically significant differences. The recurrence rate of type 2 AIP was lower than that of type 1 AIP (0 vs 16%). Conclusions:Type 2 AIP has different clinical characteristics from type 1 AIP. Due to the lack of specific serum markers, the diagnosis is more difficult. It responds well to glucocorticoids and has a low recurrence rate.

Objective To investigate the current situation and health effects of indoor microbial pollution in Xi'an, to analyze the purification effect of air purifiers on indoor microbial pollution, and to provide reference for improving the indoor environment. Methods Through stratified random sampling, 20 families from rural areas and 20 families from upwind and downwind urban areas respectively were selected from Xi'an. Data was collected by questionnaire surveys and on-site environmental sampling. Non-parametric analysis and correlation analysis were used for statistical analysis. Results Overall, the standard-exceeding rate of total count of bacteria was 5.00%. The medians of the total count of bacteria and fungi were 312.50 cfu/m3 and 260.00 cfu/m³, respectively. In terms of health effects, the correlation between rhinitis and cold with total bacterial count was statistically significant (P<0.05), with the correlation coefficients of 0.182 and 0.223, respectively. Purification effect of air purifiers on microbial pollution was statistically significant (P<0.05). After opening for 2 hours, the total numbers of bacteria and fungi decreased significantly. Conclusion The occurrence risk of colds and rhinitis is increased by indoor microbial pollution. Air purifiers have a certain effect on decreasing the total number of bacteria and fungi. It is recommended to use air purifiers with high CADR of particulate matter, double-layer filter and sterilization and dehumidification function, and replace the filters regularly to reduce indoor microbiological contamination.
