Objective: Therapeutic plasma exchange (TPE) rapidly removes harmful substances from the blood by physical means, while replacing with exogenous fluids such as fresh frozen plasma and/or albumin, thus alleviating clinical symptoms and mitigating organ injury. It is widely used in the treatment of renal, hematological, digestive, and immune-mediated diseases. This review summarizes the application of plasma exchange in hematological diseases based on the latest research evidence, focusing on its current clinical status in autoimmune hemolytic anemia, thrombotic microangiopathy, hyperviscosity syndrome secondary to hypergammaglobulinemia, and cryoglobulinemia. Based on recent evidence, we analyze its efficacy, safety management, and optimized therapeutic strategies. We also discuss the limitations and future directions of TPE in hematological diseases, aiming to provide a reference for clinical practice and research.

Objective:To summarize the early clinical outcomes of aortic valve replacement(AVR) using the Perceval sutureless aortic valve.Methods:This retrospective study included 50 patients who underwent AVR with the Perceval sutureless prostheses at Beijing Anzhen Hospital between June 2023 and January 2025. Surgical parameters, early clinical outcomes, valve function, and hemodynamic performance were evaluated to summarize clinical effectiveness.Results:The mean age of patients was(63.5±9.1) years, predominantly female(36/50). Severe aortic stenosis was present in 43 cases(86.0%). A preoperative aortic annulus dimension of 20.0(19.0, 21.0) mm measured in both anteroposterior and transverse diameters. Preoperative peak transvalvular gradient was(92.7±31.0)mmHg(1 mmHg=0.133 kPa), with a mean gradient of (58.0±21.2) mmHg. All procedures were successfully completed using the Perceval sutureless prostheses. Isolated AVR was performed in 20 patients(40.0%), with cardiopulmonary bypass and aortic cross-clamp times of 75.0(50.5, 99.5) min and 50.5(29.5, 71.5) min, respectively. Postoperative transesophageal echocardiography revealed an immediate reduction in the peak transvalvular gradient to 11.0(8.0, 18.0) mmHg, significantly lower compared to preoperative measurements( P<0.001). Two cases of paravalvular leakage and one case requiring permanent pacemaker implantation were reported postoperatively. All patients completed the 3-month follow-up, with one death during the follow-up period; the remaining patients exhibited normal prosthetic valve function without major adverse cardiovascular events. Significant postoperative reductions were observed in left ventricular end-diastolic diameter(45.8 mm vs. 43.2 mm, P=0.003) and left atrial diameter(53.9 mm vs. 44.6 mm, P<0.001) compared with baseline. Conclusion:AVR using the Perceval sutureless prostheses demonstrated safe and effective early clinical outcomes with excellent hemodynamic performance and low incidence of postoperative paravalvular leakage and permanent pacemaker implantation. The sutureless technique represents a viable alternative strategy, particularly advantageous for patients with small aortic annuli or complex surgical conditions, warranting broader clinical adoption.

Objective:To analyze the prenatal ultrasonographic features and prognosis of fetal perirenal urinoma.Methods:This retrospective study included eight fetuses with perirenal urinoma diagnosed by prenatal ultrasound in the Women and Children's Hospital of Chongqing Medical University from January 2017 to August 2023. Descriptive analysis was performed on their prenatal ultrasonographic features, intrauterine intervention measures, postnatal treatment, and prognosis.Results:Among the eight cases, the prenatal ultrasonographic diagnosis was consistent with the postnatal clinical diagnosis in seven cases, with one misdiagnosis (postnatally confirmed as giant renal cyst with multicystic dysplastic kidney). Prenatal ultrasonographic features of fetal perirenal urinoma included cystic mass adjacent to the renal capsule; obvious compression of the surrounding organs and the affected kidney; increased craniocaudal diameter of the affected kidney with thin parenchyma, increased echogenicity, indistinct corticomedullary differentiation, and pyeletasis; poorly visualized partial renal arteries; normal or mildly enlarged contralateral kidney; adequate bladder filling; normal amniotic fluid volume. Two cases underwent intrauterine cyst aspiration with subsequent cyst size reduction (slight re-enlargement during follow-up). Among the remaining six untreated cases, one case showed stable cyst size, while five cases exhibited initial significant cyst enlargement followed by stabilization or regression trend. All eight cases were born at full term (three delivered vaginally and five by cesarean section). The affected kidney was significantly atrophied within one week after birth by ultrasound observation. Impaired function of the affected kidney was shown in four patients by follow-up after discharge (including two cases of intrauterine treatment),one case abandoned treatment due to other illnesses, two cases were lost to follow-up after discharge.Conclusions:Prenatal ultrasound images of perirenal urinary cysts infetuses exhibit typical features. Intrauterine treatment can reduce the compression of large cysts and hydronephrosis on fetal organs, but there is no significant improvement in the recovery of renal function.

Objective:To investigate the clinical characteristics of patients with hepatitis B virus(HBV)-related primary hepatocellular carcinoma(HCC)who were treated in a multidisciplinary team(MDT)for liver cancer,so as to provide a basis for clinical optimization of the diagnosis and treatment of patients with chronic hepatitis B(CHB).Methods:A retrospective analysis was performed for 482 HBV-related HCC patients who were treated with HCC-MDT every Thursday afternoon in The First Affiliated Hospital of the Army Medical University from January 2022 to May 2024,aged 18-87(55.54±10.84)years,86.93%(419/482)males and 13.07%(63/482)females. According to the different underlying liver diseases at the time of initial medical treatment and the different prognostic outcomes at the later follow-up,the differences in clinical characteristics between groups under different conditions were compared and analyzed,and the influencing factors of HCC prognosis were understood by Logistic regression analysis. Results:At the time of MDT presentation,the differences in HBeAg status( χ2=6.311 ,P=0.043),γ-glutamyl traspeptidase(GGT)( Z=6.277, P=0.043),alkaline phosphatase(ALP)( Z=7.236 ,P=0.027),and model for end-stage liver disease(MELD)scores( Z=6.111, P=0.047)among patients with different underlying liver diseases were statistically significant. At follow-up,6.75%(11/163)of HBV-related HCC patients who presented to MDT had a family history of HCC,and their cumulative mortality rate was as high as 60.8%(205/337)at least for 1 year. Mulitivariate Logistic regression analysis showed that different underlying liver disease at the time of initial medical treatment,HBV DNA replication level,MELD score and choice of anti-cancer treatment regimen were the influencing factors for the prognosis of HCC(all P<0.05). The worse the degree of cirrhosis at the initial presentation,the higher the level of HBV DNA replication,and the higher the MELD score,the worse the prognosis for HCC. Conclusion:Advancing the diagnosis and treatment of CHB,maximizing the inhibition of HBV DNA replication,reducing the MELD score,and optimizing the anti-cancer treatment regimen can reduce the mortality rate of HBV-related HCC.

Aim To verify the therapeutic effect of the Qushi Huoxue decoction(QSHXF)on a mouse model of non-alcoholic fatty liver disease(NAFLD)using network pharmacology and experimental approaches,to examine the changes in the PI3K-AKT-lipid metabo-lism signaling pathway,and to elucidate its molecular mechanisms.Methods The potential active ingredi-ents and targets of the QSHXF were identified using the TCMSP platform.NAFLD-related genes were sourced from the GeneCards,PharmGkb,TTD,and OMIM data-bases.The intersection of drug targets and NAFLD treatment targets was analyzed to identify the key tar-gets of the QSHXF in treating NAFLD.The STRING database and Cytoscape 3.9.1 software were utilized to construct networks linking traditional Chinese medicine active ingredients to disease targets and PPI networks,allowing for the screening of key active ingredients and core targets.GO and KEGG enrichment analyses of the intersecting targets were conducted using R version 4.2.2.The NAFLD model was established by feeding mice a methionine-choline deficient diet for a duration of five weeks.Following successful modeling,low,me-dium,and high doses of the QSHXF were administered for intervention over a period of six weeks.The efficacy was verified and the underlying mechanisms were ex-plored using methods such as HE staining,Oil Red O staining,and Western blot analysis.Results The net-work pharmacology prediction indicated that QSHXF might effectively treat NAFLD through key components such as quercetin and kaempferol,as well as core tar-gets including STAT3,AKT1,and HIF1A.KEGG en-richment analysis further suggested that QSHXF might exert its therapeutic effects on NAFLD via signaling pathways such as AGE-RAGE and PI3K-AKT.Verifi-cation through animal experiments demonstrated that QSHXF could significantly reduce hepatic steatosis and lipid droplet accumulation in NAFLD mice.Specifical-ly,it markedly decreased serum levels of TC,TG,ALT,AST,and LDL,while increasing HDL levels.Addition-ally,the treatment significantly reduced the protein ex-pression levels of p-PI3K,p-AKT,SREBP-1c,FASN,and ACC1 in the liver.Conclusions QSHXF can sig-nificantly enhance liver function,improve blood lipid levels,and alleviate hepatic steatosis in NAFLD mice,with its mechanism potentially linked to the inhibition of the PI3K-AKT-lipid metabolism signaling pathway.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a common chronic liver disease with the pathological feature of lipid accumulation in the liver, and it is closely associated with liver metabolic disorders. The latest research has shown that the pathogenesis of MAFLD is associated with the abnormal expression of specific genes, especially the fat mass and obesity-associated (FTO) gene. The abnormal activity of the FTO gene may lead to an imbalance in liver lipid metabolism, which manifests as the increase in fatty acid synthesis and the reduction in fatty acid oxidation, thereby promoting liver fat deposition and inflammatory response. Therefore, regulating the expression or activity of the FTO gene is considered one of the potential strategies for the treatment of MAFLD. At present, drug research targeting the function of the FTO gene has achieved preliminary results, and inhibition of the activity of the FTO gene can help to regulate liver lipid metabolism and alleviate liver inflammatory injury. This article reviews the mechanism of action of the FTO gene in the development and progression of MAFLD, summarizes the advances in drug research on the FTO gene and related metabolic pathways in recent years, and analyzes their application prospect in research and treatment.

OBJECTIVES:
To explore the status and risk factors of neuropsychological development in small for gestational age (SGA) infants at corrected 12-24 months of age.
METHODS:
Clinical data were retrospectively collected for 754 SGA infants at corrected ages 12-24 months in Shenzhen Bao'an Women and Children's Hospital between April 2018 and December 2023. Developmental quotient (DQ) levels were analyzed. According to the presence of global developmental delay (GDD), participants were divided into a GDD group (71 cases) and a control group (683 cases), and the incidence and influencing factors of GDD were investigated.
RESULTS:
In the high-risk preterm SGA group, the total DQ and DQ in all domains were lower than in the full-term SGA group (P<0.017). The overall incidence of GDD was 9.4% (71/754) and increased with decreasing gestational age (P<0.017). Compared with the control group, the GDD group had higher proportions of males; low-risk and high-risk preterm birth; mothers with less than a bachelor's degree; multiple birth; neonatal hypoglycemia; neonatal pneumonia; neonatal respiratory distress syndrome; bronchopulmonary dysplasia; and, at corrected 12-24 months, low body weight, growth retardation, and microcephaly. The length of neonatal hospital stay was longer in the GDD group than in the control group (P<0.05). The weight-for-age Z score, length-for-age Z score, and head circumference-for-age Z score at birth and at corrected 12-24 months were lower in the GDD group than in the control group (P<0.05). Multivariable logistic regression showed that male sex and maternal education below a bachelor's degree were independent risk factors for GDD in SGA infants (P<0.05).
CONCLUSIONS
Neuropsychological development in preterm SGA infants is comparatively delayed; male SGA infants born to mothers with less than a bachelor's degree should receive priority attention.
