ObjectiveINF2 is a member of the formins family. Abnormal expression and regulation of INF2 have been associated with the progression of various tumors, but the expression and role of INF2 in hepatocellular carcinoma (HCC) remain unclear. HCC is a highly lethal malignant tumor. Given the limitations of traditional treatments, this study explored the expression level, clinical value and potential mechanism of INF2 in HCC in order to seek new therapeutic targets. MethodsIn this study, we used public databases to analyze the expression of INF2 in pan-cancer and HCC, as well as the impact of INF2 expression levels on HCC prognosis. Quantitative real time polymerase chain reaction (RT-qPCR), Western blot, and immunohistochemistry were used to detect the expression level of INF2 in liver cancer cells and human HCC tissues. The correlation between INF2 expression and clinical pathological features was analyzed using public databases and clinical data of human HCC samples. Subsequently, the effects of INF2 expression on the biological function and Drp1 phosphorylation of liver cancer cells were elucidated through in vitro and in vivo experiments. Finally, the predictive value and potential mechanism of INF2 in HCC were further analyzed through database and immunohistochemical experiments. ResultsINF2 is aberrantly high expression in HCC samples and the high expression of INF2 is correlated with overall survival, liver cirrhosis and pathological differentiation of HCC patients. The expression level of INF2 has certain diagnostic value in predicting the prognosis and pathological differentiation of HCC. In vivo and in vitro HCC models, upregulated expression of INF2 triggers the proliferation and migration of the HCC cell, while knockdown of INF2 could counteract this effect. INF2 in liver cancer cells may affect mitochondrial division by inducing Drp1 phosphorylation and mediate immune escape by up-regulating PD-L1 expression, thus promoting tumor progression. ConclusionINF2 is highly expressed in HCC and is associated with poor prognosis. High expression of INF2 may promote HCC progression by inducing Drp1 phosphorylation and up-regulation of PD-L1 expression, and targeting INF2 may be beneficial for HCC patients with high expression of INF2.

Objective: To identify an optimal back-flush solution for leukocyte-depleted filters that maximizes peripheral blood mononuclear cell (PBMC) recovery with high viability, long-term storage stability, and sterility of the harvested residues, thereby providing a clinically translatable strategy. Methods: Three sterile bag-packaged solutions—Saline, Solvent, and Hanks' balanced salt solution (HBSS)—were used to back-flush randomly assigned leukocyte-depleted filters. Nucleated cell recovery rate and viability of the harvested residues were compared. The optimal solution identified was applied to an expanded sample set. PBMC viability and yield were evaluated after 1h vs 48h storage of the residues. PBMCs isolated from the residues were cryopreserved in liquid nitrogen for 1 month, followed by post-thaw comparisons of viability and T-cell expansion capacity. Results: The Solvent group achieved the highest and most consistent nucleated cell recovery rate. Post-flush recovery rate from filters after 400 mL whole blood processing was (21.3±1.6)% for the Solvent group, significantly higher than Saline group (19.2±6.3)% and HBSS group (11.2±5.0)%, with residues from all groups maintaining viability >90%. No biologically significant difference in residue viability was observed between 48h vs 1h storage groups (93.3±2.3)% vs (95.7±1.8)%). PBMC recovery rates from residues showed no statistical difference between 48h vs 1h storage groups [(48.2%±9.5%)vs (40.41%±8.35%), P>0.05], with (17.7±2.6)×10 cells. After 1-month cryopreservation and 10-day expansion, PBMCs isolated from 48-hour-stored residues retained (91.2±3.2)% viability and achieved a (61.9±15.9)-fold expansion. Conclusion: The bag-packaged Solvent, as a back-flush solution, enables sterile acquisition of leukocyte-depleted filter residues through closed-system tubing connections. These residues maintained PBMC viability and recovery rates after 48h storage at 2℃-8℃, with post-cryopreservation (1-month liquid nitrogen) viability and expansion capacity remaining stable. This protocol complies with blood bank regulatory criteria, addresses the concerns about the infectious window period in cell therapy raw materials, and provides a clinically translatable strategy for PBMC-based applications.

Objective To evaluate the intraoperative identification of ectopic parathyroid tissue in the central neck region using autofluorescence point-spectral analysis(AFPSA)combined with immune colloidal gold technique(ICGT),for guiding total parathyroidectomy(TPTX)or clean parathyroidectomy(CPTX)in the management of secondary hyperparathyroidism(SHPT).Methods Retrospectively collected and compared the clinical data of 64 patients with SHPT from October 2019 to June 2023.In the observation group,TPTX was performed as the initial procedure in 36 cases,followed by sampling of suspicious targets using AFPSA in the central neck area and subsequent detection through ICGT.CPTX was then conducted if a positive result was obtained.On the other hand,the control group consisted of 28 cases where only TPTX was performed without any additional tests during surgery.The surgical data,parathyroid hormone(PTH)levels,blood calcium levels,blood phosphorus levels,alkaline phosphatase(ALP)levels,regression of clinical symptoms,changes in parathyroid function and occurrence of hypocalcemia were compared between these two groups.Results In the observation group,there were 9 cases of AFPSA-ICGT positivity,including 2 left-sided cases,4 right-sided cases,and 3 thymic cases;among these posi-tive cases,there were a total of 10 locations with mildly hyperplastic or nonhyperplastic microscopic parathyroid tissue.The difference in the number of total parathyroid glands removed(including ectopic)between the two groups was statistically significant(P<0.05).At both 3 and 6 months postoperatively,ALP levels in the observation group were significantly lower than those in the control group(P<0.01 and P<0.001 respectively);at 6 months postoperatively,differences in PTH and blood phosphorus levels between the two groups were also statistically significant(P<0.05 and P<0.001 respectively).Joint bone pain and skin itching recurred in some patients within the control group at six months after surgery(P<0.05),whereas recurrence of SHPT was less frequent within the observation group compared to controls(P<0.05);however,no statistically significant differences were observed regarding postoperative hypoparathyroidism or hyperparathyroidism as well as hypocalcemia between either groups.Conclusion The AFPSA-ICGT intraoperative test can be utilized to guide surgery for SHPT,enabling accurate and efficient identification as well as safe targeting of parathyroid tissues that may not exhibit obvious hyperplasia in the central cervical region.

Objective:To explore the clinical efficacy and cardiovascular protective effect of sodium-glucose co-transporter 2 inhibitor(SGLT-2i)on patients with type 2 diabetic nephropathy(T2DN).Methods:A total of 376 T2DN patients admitted in our Department of Endocrinology and Department of Cardiology from January 2018 to December 2021 were selected.According to therapeutic program,they were divided into control group(n=177,re-ceived routine treatment program)and SGLT-2i group(n=199,received SGLT-2i based on routine treatment program),both groups were continuously treated for 1 year.Blood glucose,blood pressure,blood lipids,uric acid,body mass index,renal function-related indexes and the occurrence of major adverse cardiovascular events were compared between the two groups after 12 months,as well as the adverse drug reactions.Results:After 12-month treatment,compared with control group,there were significant reductions in levels of blood pressure,fasting blood glucose(FBG),glycosylated hemoglobin A1e(HbA1c),urinary albumin/creatinine ratio(UACR),creatinine(Cr),blood urea nitrogen(BUN),total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C)and uric acid(UA),and significant rise in estimated glomerular filtration rate(eGFR),levels of high density lipoprotein cholesterol(HDL-C),albumin(Alb)and alanine aminotransferase(ALT)in SGLT-2i group(P＜0.05 or＜0.01).Incidence rates of acute myocardial infarction(1.51％vs.6.21％)and heart failure caused-readmission(2.51％vs.6.78％)in SGLT-2i group were significantly lower than those of control group,and inci-dence rate of urinary system infection(8.54％vs.1.69％)was significantly higher than that of control group(P＜0.05 all).Conclusion:SGLT-2i can not only effectively control blood glucose,but also reduce body weight and blood pressure,improve blood lipids,reduce uric acid,improve renal hyperfiltration,reduce urinary protein and possess unique cardiovascular benefits,but risk of urinary system infection calls for attention.

Objective To explore the application of drones in blood emergency support during the 19th Asian Games Hangzhou in Shaoxing venue,so as to provide reference for future major events.Methods A retrospective analysis of drone delivery of emergency blood to two designated rescue hospitals in Shaoxing for the Asian Games was conducted.Ten emer-gency and 30 routine land blood delivery records from two designated hospitals in 2023 were randomly selected to compare with the blood delivery using drones.The blood temperature during the drone flight were monitored,the cold chain control during drone flight was evaluated,and the application of drone flight was reviewed.Results During the Hangzhou Asian Games,a total of 14 drones were used for blood delivery.The delivery time(min)by drone from the blood station to one of the designated hospitals was 11.83±0.09,and 20.80±3.29 by emergency land delivery and 23.23±3.54 by routine land de-livery(P＜0.05),meanwhile was 17.50±0.08,24.50±3.27 and 26.57±3.23 respectively to the other hospital(P＜0.05).Compared with land emergency blood delivery and routine blood delivery,blood delivery time by drone was much shorter,demonstrating better timeliness and stability.The temperature monitoring during the drone delivering showed that the suspen-ded red blood cells and platelets were in a range of 3.8-6.8℃ and 21.8-22.8℃,with a temperature difference of 0.5-0.9℃ and 0.2-1.0℃ between takeoff and landing respectively,demonstrating that the blood cold chain was under control,and the delivery ran safely and smoothly.Conclusion During major events,the use of drones for emergency blood delivery ensures the quality of the blood,with good timeliness,feasibility and operability,and is worthy of promotion and applica-tion.

Objective To observe the alteration of thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis(AIS)and the difference of physiological curvature between different types of scoliosis.Methods A retrospective analysis was conducted on 305 adolescent patients taken full spine X-ray in our hospital from January 2017 to December 2021.The patients were divided into normal group and scoliosis group.The normal group was composed of 179 patients,79 males and 100 females,aged 10 to 18 years old with an average of(12.84±2.10)years old,with cobb agle less than 10 degrees.The scol-iosis group was composed of 126 patients,33 males and 93 females,aged 10 to 18 years old with an average of(13.92±2.20)years old.The gender,age,Risser sign,thoracic kyphosis(TK)and lumbar lordosis(LL)in 2 groups were compared,and the TK and LL were also compared between different genders,different degrees of scoliosis and different segments of scoliosis.Re-sults The female ratio(P=0.001)and age(P＜0.001)in scoliosis group were higher than them in normal group;the ratio of low-grade ossification was higher in normal group than in scoliosis group(P=0.038).TK was significantly smaller in scoliosis group than in normal group(P＜0.001),but there was no significant difference in LL between the 2 groups(P=0.147).There were no significant difference in TK and LL between male and female.The TK was significantly bigger in mild AIS patients than in moderate AIS patients(P＜0.05),but there was no significant difference in LL between mild and moderate patients(P＞0.05).The TK and LL in different segments scoliosis were not found significant difference.Conclusion The physiological curvature of thoracic and lumbar spine is independent of gender.The thoracic physiological curvature becomes smaller in AIS patients,but lumbar curvature remains unchanged.The thoracic physiological curvature in mild AIS patients is greater than that in moderate AIS patients,but the lumbar curvature is almost unchanged between mild and moderate scoliosis and is similar with that in normal adolescent.The alteration of thoracic and lumbar physiological curvature in AIS patients may be related to relative an-terior spinal overgrowth,and the specific detailed mechanism needs to be further studied.

Background::Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.Methods::Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.Results::A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43–0.68; P <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04–13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65–3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38–1.53; P <0.001). Conclusions::In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration::ClinicalTrials.gov, NCT02309398.
