Objective:To analyze the efficacy of laparoscopic partial splenectomy and devascularization (LPSPD), open partial splenectomy and devascularization (OPSPD), laparoscopic total splenectomy and devascularization (LTSPD), and open total splenectomy and devascularization (OTSPD) in the treatment of portal hypertension.Methods:Clinical data of 128 patients with portal hypertension admitted to the Department of Hepatobiliary and Pancreatic Surgery of the Affiliated Hospital of Qinghai University and the General Surgery Department of the Fifth Medical Center of the Chinese PLA General Hospital from May 2018 to May 2022 were retrospectively analyzed, including 69 males and 59 females, aged 51.0±10.9 years. According to different surgical methods, patients were divided into four groups, namely the LPSPD group ( n=30), the OPSPD group ( n=32), the LTSPD group ( n=31), and the OTSPD group ( n=35). Operation time, postoperative hospitalization time, postoperative complications such as newly occurred PVT, etc of the four groups of patients were compared. Results:The operation times of the LPSPD, OPSPD, LTSPD and OTSPD group were 240.0 (180.0, 399.0), 209.5 (169.0, 259.0), 207.0 (175.3, 297.5) and 200.0 (162.0, 264.0) minutes, respectively. The postoperative hospital stays were 8.0 (7.0, 12.0), 10.0 (8.3, 11.8), 11.0 (9.0, 13.0) and 13.0 (11.0, 15.0) days, respectively. The incidences of newly occurred PVT after surgery were 3.3% (1/30), 3.1% (1/32), 19.4% (6/31), and 20.0% (7/35), respectively. The above indicators were compared among the four groups respectively, and the differences were statistically significant (all P<0.05). The postoperative hospital stay of the LPSPD group was shorter than that of the LTSPD group [8.0 (7.0, 12.0) vs 11.0 (9.0, 13.0), d, Z=-3.93], and the postoperative hospital stay of the OPSPD group was also shorter than that of the OTSPD group [10.0 (8.3, 11.8) vs 13.0 (11.0, 15.0), d, Z=-3.56; all P<0.001]. The incidence of newly occurred PVT after surgery in the partial splenectomy group (LPSPD and OPSPD) was 3.2% (2/62), which was lower than that in the total splenectomy group [LTSPD and OTSPD, 19.7% (13/66), χ2=8.38, P=0.004]. Conclusion:Compared to total splenectomy, partial splenectomy might be favorable for the shortened postoperative hospital stay and lower incidence of newly occurred portal vein thrombosis.

Objective:To investigate the use of apolipoprotein B (ApoB) diagnostic algorithm for hyperlipidemia typing combined with whole exome sequencing in the precise diagnosis of familial hyperlipidemia.Methods:A retrospective observational study was conducted by collecting clinical information on all patients who attended our hospital, and had their lipid levels tested from January 2023 to May 2024, including 440 patients with low-density lipoprotein cholesterol (LDL-C)>4.10 mmol/L. Family history, current lipid levels, medication use, and comorbidities were collected by telephone follow-ups. Among them, 10 patients had a family history of hyperlipidemia. Peripheral venous blood samples were collected from patients with a family history of hyperlipidemia, and whole exome sequencing was performed.Results:According to the Fredrickson typing of WHO, 10 patients (P1 to P10) could be categorized into two groups, of which only type Ⅱa could be excluded in 6 cases, and the typing could not be determined in 4 cases. The ApoB diagnostic algorithm of hyperlipidemia typing could classify patients P1 and P2 as type Ⅱa, patients P3 to P7, P9 and P10 as type Ⅱb, and patient P8 as type Ⅴ, respectively. Whole exome sequencing detected mutations in LDLR, PCSK9, C5AR2, KIF12, ALMS1, ABCG5, COL4A3, and MTTP genes.Conclusion:The ApoB diagnostic algorithm for hyperlipidemia can be used for accurate typing of hyperlipidemia, and ApoB could be recommended as a routine lipid testing parameter. The ApoB diagnostic algorithm for hyperlipidemia combined with whole exome sequencing could be used for the accurate typing of patients with familial hyperlipidemia and defining the underlying gene mutations.

Objectives:To investigate the predictive value of Murray's law-based quantitative flow ratio(μQFR)in side branches for long-term clinical prognosis in patients with non-left main bifurcation lesions who underwent simple main branch stenting,and to provide a potential functional assessment standard for intervention decision-making on coronary bifurcation lesions.Methods:A retrospective analysis was conducted in 408 patients with non-left main bifurcation lesions who underwent simple main branch stenting at Lianyungang First People's Hospital and Nanjing First Hospital between July 2018 and January 2021.The study utilized third-generation QFR software to analyze pre-and post-procedure anatomical and functional parameters of the target lesion's main branch and key branches.The primary endpoint was target vessel failure(TVF)events during the 3-year follow-up.Patients were stratified into TVF and non-TVF groups.Baseline characteristics,procedural data,and pre-/post-procedural parameters of target vessels were compared between groups.Multivariable Cox regression was performed to identify predictors of TVF.Diagnostic efficacy of predictors was evaluated using area under the receiver operating characteristic(ROC)curve(AUC)with DeLong's method for comparison.Patients were dichotomized based on the optimal cutoffof post-procedural side branch μQFR,with TVF incidence rates compared via Cox regression and Kaplan-Meier analysis.Results:During 3-year follow-up,54 patients(13.2%)experienced TVF(TVF group),data were compared with 354 patients(86.76%)without TVF(non-TVF group).The TVF group showed higher post-procedural side branch diameter stenosis([32.93±17.80]%vs.[22.62±11.96]%,P<0.001)and lower μQFR(0.80±0.10 vs.0.89±0.07,P<0.001).Multivariate Cox regression identified higher post-procedural side branch μQFR as an independent protective factor against 3-year TVF(per 0.01 increase:HR=0.903,95%CI:0.850-0.959,P<0.001).ROC curves indicated that post-procedural side branch μQFR had moderate diagnostic efficacy for predicting 3-year TVF(AUC=0.769,95%CI:0.678-0.861,P<0.001),with a significantly higher AUC value than post-operative side branch area stenosis and minimal lumen diameter(both P<0.001),the optimal cutoffvalue was 0.84.Multivariate Cox regression and Kaplan-Meier survival analysis revealed markedly higher 3-year TVF rates in patients with μQFR≤0.84 compared to patients with μQFR>0.84(HR=4.007,95%CI:2.342-6.855,P<0.001;28.3%vs.7.9%,log-rank P<0.001).Conclusions:For patients with bifurcation lesions not involving the left main,the immediate post-procedural side branch μQFR could better predict 3-year TVF than anatomical indices.Maintaining post-stenting side branch μQFR>0.84 may optimize clinical outcomes when using a single-stent strategy.

Objective To screen and analyze key genes in rabbit corneal alkali burns based on transcriptomics se-quencing technology and bioinformatics techniques.Methods Thirty healthy male New Zealand rabbits were randomly di-vided into 2 groups(n=15 per group):The control group received no intervention,while the alkali burn group underwent corneal alkali burn modeling.Histological evaluation of corneal tissues was performed via hematoxylin-eosin(HE)stai-ning.Transcriptome sequencing was conducted for library construction and sequencing.Differentially expressed genes(DEGs)were identified using DESeq2,followed by Gene Ontology(GO)functional enrichment analysis and Kyoto Ency-clopedia of Genes and Genomes(KEGG)pathway analysis.A protein-protein interaction(PPI)network was constructed to screen hub genes,and RT-PCR was employed to validate mRNA expression levels of key genes.Results HE staining revealed orderly arranged corneal stromal layers and scattered stromal cells in the control group,whereas the alkali burn group exhibited stromal edema,thickened collagen fibers with loose/disorganized alignment,and increased fibroblast and inflammatory cell infiltration.Compared to the control group,1 827 significant DEGs were identified in the alkali burn group,including 1 495 upregulated and 332 downregulated genes.GO analysis showed biological processes such as immune response,plasma membrane,and identical protein binding.KEGG analysis indicated that DEGs were enriched in pathways related to cancer,lipid and atherosclerosis,and neuroactive ligand-receptor interaction.The PPI network screened 11 key genes:neutrophil cytosolic factor 1(NCF1),neutrophil cytosolic factor 2(NCF2),matrix metallopeptidase 2(MMP2),ma-trix metallopeptidase 9(MMP9),interleukin-1α(IL-1α),interleukin-1β(IL-1β),interleukin-6(IL-6),interleukin-8(CXCL8),cluster of differentiation 4(CD4),C-C motif ligand 2(CCL2)and tumor necrosis factor(TNF).RT-PCR valida-tion revealed that the mRNA expression levels of key genes in the corneal tissues of the alkali burn group were significantly higher than those in the control group(all P＜0.05),consistent with the transcriptomic sequencing results.Conclusion Based on the rabbit corneal alkali burn model,this study identified 11 key genes(NCF1,NCF2,MMP2,MMP9,IL-1α,IL-1β,IL-6,CXCL8,CD4,CCL2 and TNF)through transcriptomics and bioinformatics analysis.

Objective This study aimed to investigate the effects of sleep interruption(SI)cycles on emotional behavior in ICR mice,and to establish a mouse model of comorbid anxiety and depression induced by SI.Methods Seventy-two male ICR mice(4～5 weeks old)were divided randomly into a blank group and a model group.Mice in the model group were subjected to SI stress modeling for 1,2,and 3 weeks,respectively.After modeling,emotional behaviors were evaluated using open-field,elevated plus maze,light-dark box,marble-burying,and forced-swimming tests.Serum corticosterone levels were detected by enzyme-linked immunosorbent assay.Results Mice in the model group buried significantly more marbles after 1 week of SI stress,compared with the blank group(P＜0.05).After 2 weeks of stress,mice in the model group also showed a significant decrease in the number of crossings in the light-dark box(P＜0.05)and a significant increase in the number of marbles buried(P＜0.01)compared with the control group.After 3 weeks of stress,mice in the model group showed a significant increase in the number of marbles buried(P＜0.05),a significant decrease in the number of crossings in the light-dark box(P＜0.05),and a significant increase in immobility time in the forced-swim test(P＜0.01).Conclusions ICR mice exhibited significant anxiety-related behaviors after 2 weeks of SI modeling and significant anxiety-and depressive-related behavioral changes after 3 weeks.Three weeks of SI stress can be used to establish a model of comorbid anxiety and depression.

ObjectiveTo explore the dose-effect relationship and safety of high， medium， and low doses of raw Astragali Radix in the modified Huangqi Chifengtang （MHCD） for treating proteinuria in immunoglobulin A （IgA） nephropathy， and to provide scientific evidence for the clinical use of high-dose Astragali Radix in the treatment of proteinuria in IgA nephropathy. MethodsA total of 120 patients with IgA nephropathy， diagnosed with Qi deficiency and blood stasis combined with wind pathogen and heat toxicity， were randomly divided into a control group and three treatment groups. The control group received telmisartan combined with a Chinese medicine placebo， while the treatment groups were given telmisartan combined with MHCD containing different doses of raw Astragali Radix （60， 30， 15 g）. Each group contained 30 patients， and the treatment period was 12 weeks. Changes in 24-hour urinary protein （24 hUTP）， traditional Chinese medicine （TCM） syndrome scores， effective rate， and renal function were observed before and after treatment. Safety was assessed by monitoring liver function and blood routine. ResultsAfter 12 weeks of treatment， 24 hUTP significantly decreased in the high， medium， and low-dose groups， as well as the control group （P<0.05， P<0.01）. The TCM syndrome scores in the high， medium， and low-dose groups also significantly decreased （P<0.01）. Comparisons between groups showed that the 24 hUTP in the high-dose group was significantly lower than in the medium， low-dose， and control groups （P<0.05， P<0.01）， and the 24 hUTP in the medium-dose group was significantly lower than in the control group （P<0.05）. The TCM syndrome scores in the high and medium-dose groups were significantly lower than in the low-dose and control groups （P<0.05， P<0.01）. The total effective rates for proteinuria in the high， medium， low-dose， and control groups were 92.59% （25/27）， 85.19% （23/27）， 60.71% （17/28）， and 57.14% （16/28）， respectively. The effective rates in the high and medium-dose groups were significantly higher than in the low-dose and control groups （χ²=13.185， P<0.05， P<0.01）. The effective rates for TCM syndrome scores in the high， medium， low-dose， and control groups were 88.89% （24/27）， 81.48% （22/27）， 71.43% （20/28）， and 46.43% （13/28）， respectively. The efficacy of TCM syndrome scores in the high and medium-dose groups was significantly higher than in the control group （χ²=14.053， P<0.01）. Compared with pre-treatment values， there was no statistically significant difference in eGFR and serum creatinine in the high and medium-dose groups. However， eGFR significantly decreased in the low-dose and control groups after treatment （P<0.05）， and serum creatinine levels increased significantly in the control group （P<0.05）. No statistically significant differences were observed in urea nitrogen， uric acid， albumin， total cholesterol， triglycerides， liver function， and blood routine before and after treatment in any group. ConclusionThere is a dose-effect relationship in the treatment of IgA nephropathy with high， medium， and low doses of raw Astragali Radix in MHCD. The high-dose group exhibited the best therapeutic effect and good safety profile.

Objective To evaluate the predictive value of dose-surface histogram(DSH)for radiation proctitis(RP)in prostate cancer(PCa)patients undergoing radiotherapy.Methods This prospective randomized controlled clinical trial included 380 PCa patients who underwent image-guided radiotherapy in the First Affiliated Hospital of Hebei Northern University from January 2018 to January 2023.Patients were randomly divided into observation group(n=200)and control group(n=180).The rectal dose distribution of patients in the two groups was evaluated by using DSH and dose-volume histogram(DVH),respectively.The receiver operating characteristic(ROC)curve was utilized to evaluate the predictive value of DSH for acute RP,with DVH serving as a reference.Results The difference was not statistically significant in clinical information such as age,KPS score,and body mass index(BMI)between the observation and control groups(P＞0.05),as well as in acute RP incidence(P＞0.05).There were significant differences in S40 and V40,S50 and V50,S60 and V60,S70 and V70,and S78 and V78 between the two groups(P＜0.05).S40,S50,V40,and V50 showed low efficacy(P＜0.001)in predicting acute RP at each level,with AUC≤0.700.S60 and V60 showed moderate efficacy(P＜0.001)in predicting acute RP at each level,with AUC 0.700-0.900.S70,S78,V70 and V78 showed high efficacy(P＜0.001)in predicting acute RP at each level,with AUC＞0.900.Conclusions The predictive value of DSH for rectal toxicity in patients with PCa is basically consistent with that of DVH.It is expected to become a novel and valuable tool for evaluating radiotherapy plans in the future.
