ObjectiveTo observe the clinical efficacy and safety of Yuyin Lidan granules （YYLD） in preventing the recurrence of common bile duct stones （CBDS） in patients with liver and gallbladder dampness-heat syndrome following endoscopic retrograde cholangiopancreatography （ERCP）. MethodsThis randomized， parallel， controlled trial enrolled postoperative CBDS-ERCP patients who met the inclusion and exclusion criteria. Sixty-four patients were randomly assigned to an observation group or a control group， with 32 cases in each. Both groups received conventional Western medical treatment after ERCP， while the observation group additionally received YYLD for 8 weeks. The follow-up period lasted for 1 year. The efficacy indicators included bile bilirubin levels， traditional Chinese medicine （TCM） syndrome scores， clinical efficacy rate， pancreatitis and inflammation markers， postoperative liver function， and CBDS recurrence rate at 1-year follow-up， which were used to jointly evaluate the clinical efficacy and safety of both groups. ResultsA total of 56 patients completed the study and were included in the final analysis， i.e.， 29 in the observation group and 27 in the control group. Baseline characteristics were comparable between the two groups. Compared with pre-treatment and with the control group after treatment， the bile bilirubin level in the observation group significantly decreased （P<0.05）. After treatment， the clinical cure and marked improvement rates were higher in the observation group than in the control group， showing a statistically significant difference in overall clinical efficacy （P<0.05）. Compared with pre-treatment， the primary and secondary symptoms in the observation group， as well as the primary symptom and the secondary symptom of nausea and vomiting in the control group （weeks 4 and 8）， were significantly reduced （P<0.05）. Compared with the control group after treatment， the observation group showed significant reductions in the primary symptom of loose stools/constipation （day 5 and week 4） and in three secondary symptoms， i.e.， bitter taste and sticky dry mouth， abdominal distension and poor appetite （throughout the treatment period）， and general heaviness and fatigue （day 5 and week 4）， with statistical differences （P<0.05）. Compared with pre-treatment， both groups showed decreased lipase and urinary amylase levels （P<0.05）. However， no significant between-group differences were observed in pancreatitis or inflammation-related indices after treatment. Compared with pre-treatment， all liver function indicators in the observation group and alanine aminotransferase （ ALT ）， γ-glutamyl transferase （ γ-GT ）， alkaline phosphatase （ALP）， and conjugated bilirubin in the control group significantly decreased at weeks 4 and 8 （P<0.05）. Compared with the control group after treatment， only serum total bilirubin and unconjugated bilirubin were significantly reduced in the observation group during the treatment period （P<0.05）. ConclusionYYLD combined with conventional Western medical treatment can effectively regulate bilirubin metabolism （in bile and serum）， improve TCM clinical symptoms， and prevent CBDS recurrence after ERCP in patients with liver and gallbladder dampness-heat syndrome. This regimen is safe and effective and is worthy of further clinical research and promotion.

ObjectiveThis paper aims to assess the effects of Wenfei Guyuan umbilical moxibustion on the quality of life and immune function in patients with chronic obstructive pulmonary disease （COPD） in stable phase. MethodsA multi-center randomized controlled trial design was employed，and the 220 cases of patients with COPD in stable phase from three grade A class-Ⅲ hospitals were included as research objects. The patients were randomly divided into the test group and control group，with each group consisting of 110 cases. Both groups received standardized treatment of western medicine，and the test group received Wenfei Guyuan umbilical moxibustion twice weekly for 13 weeks，followed by a 26-week follow-up period. Quality of life was evaluated by using the COPD assessment test （CAT），the modified COPD patient-reported outcomes （mCOPD-PRO） measure，and the modified effectiveness satisfaction questionnaire for COPD （mESQ-COPD） before treatment，four weeks， eight weeks， and 13 weeks of the treatment period，as well as 13 weeks and 26 weeks of the follow-up period. The number of acute exacerbation cases of patients in both groups was recorded during study period to evaluate the effect of Wenfei Guyuan umbilical moxibustion on acute exacerbations. 30 cases were randomly selected in both observation group and control group. Peripheral blood samples were collected before treatment and at 13 weeks of treatment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of immunoglobulin A （IgA），immunoglobulin G （IgG），immunoglobulin M （IgM），interleukin 10 （IL-10），interleukin 17A （IL-17A），transforming growth factor β1 （TGF-β1），and tumor necrosis factor α （TNF-α）. Flow cytometry was used to detect cluster of differentiation 4 positive （CD4⁺），cluster of differentiation 8 positive （CD8⁺），T helper 17 （Th17），and Treg levels， thereby preliminarily exploring the effect of Wenfei Guyuan umbilical moxibustion on immune function. ResultsA total of 220 patients were included，with five cases dropping out. 215 cases were finally included in the per-protocol set，including 107 in the treatment group and 108 in the control group. Baseline characteristics of the first two groups before treatment were compared between the two groups. In terms of life quality evaluation， the main effect of group differences on the CAT scores was significant （F=15.108，P<0.01）. The main effects of group differences on the physical domain （F=38.807，P<0.01），psychological domain （F=38.996，P<0.01），environmental domain （F=17.436，P<0.01），and total score of mCOPD-PRO （F=41.972，P<0.01） were significant. The main effects of group difference on clinical symptoms domain of mESQ-COPD （F=81.516，P<0.01），work-life ability domain （F=36.549，P<0.001），environmental adaptation ability domain （F=22.677，P<0.01），therapeutic effect domain （F=74.055，P<0.01），and total score of mESQ-COPD （F=73.251，P<0.01） were significant. Regarding acute exacerbations，during the entire study period，as well as the treatment period and follow-up period，the observation group showed fewer patients experiencing acute exacerbations compared to the control group，but the difference between the two groups was not statistically significant. In terms of immune indicators，after 13 weeks of treatment，the levels of IgA，IgG，and IgM in the observation group were significantly better than those in the control group （P<0.05）. The level of IL-10 was significantly higher than that in the control group （P<0.05），and the levels of IL-17A，TGF-β1，and TNF-α were significantly lower than those in the control group （P<0.05）. Compared with those in the control group，the level of CD4⁺/CD8⁺ in the observation group was significantly increased （P<0.05），while the levels of CD4⁺ and Treg were slightly increased，but the difference was not statistically significant. The levels of CD8⁺，Th17，and Th17/Treg were significantly decreased （P<0.05）. ConclusionWenfei Guyuan umbilical moxibustion can improve the quality of life， and immune function in patients with COPD in stable phase. It is worth promoting in clinical practice.

IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and a major cause of chronic kidney disease and kidney failure. IgAN exhibits marked heterogeneity in clinical presentation, histopathology, and pathogenic mechanisms, contributing to variable treatment responses and prognosisamong patients. Precise risk assessment and individualized intervention are therefore of critical importance. This review systematically traces the evolution of IgAN management from traditional risk stratification toward biomarker-driven precision medicine. We first review the clinical utility and limitations of established risk stratification tools, including the KDIGO guidelines, the Oxford MEST-C classification, and the International IgAN Prediction Tool. We then discuss emerging biomarkers closely linked to disease pathogenesis, including galactose-deficient IgA1 (Gd-IgA1), anti-Gd-IgA1 autoantibodies, B cell activating factor (BAFF), a proliferation-inducing ligand (APRIL), and complement components, as well as the targeted therapies they have informed. In addition, urinary biomarkers and multi-omics approaches show promise for dynamic disease monitoring and individualized risk stratification.

ObjectiveThe malaria parasites remodel the host erythrocyte structure by exporting parasite proteins that interact with the membrane skeleton proteins of red blood cells (RBCs), facilitating their intracellular survival and pathogenicity. Skeleton-binding protein 1 (SBP1) is a conserved exported protein across Plasmodium species. In Plasmodium falciparum, SBP1 has been reported to interact with erythrocyte membrane skeleton proteins 4.1R and spectrin, while its contribution to erythrocyte remodeling and parasite virulence in Plasmodium berghei (Pb) remains unclear. This study aims to determine whether PbSBP1 associates with the host cytoskeletal protein 4.1R and to investigate its role in the remodeling of host RBCs and the pathogenicity of Plasmodium berghei. MethodsIn Plasmodium berghei, the relationship between PbSBP1 and the erythrocyte cytoskeletal protein 4.1R was examined using co-immunoprecipitation. A Pbsbp1 gene knockout mutant of Plasmodium berghei (Pbsbp1∆) was generated based on the principle of double crossover homologous recombination. The deformability of erythrocytes infected with Pbsbp1∆ parasites was assessed using microfluidic methods. Microchannels with an array of cylindrical pillars were used to detect modifications in infected RBC deformability. The infected RBCs were squashed between the rows and recovered between the columns and the transit velocity (μm/s) of infected RBCs travelling through the microchannel was recorded. The component of the erythrocyte membrane skeleton junctional complex, tropomodulin (TMOD), was fluorescently labeled, and the cytoskeletal network of infected erythrocytes was imaged using super-resolution stochastic optical reconstruction microscopy (STORM) to analyze ultrastructural changes in the cytoskeleton of wild-type (WT) and Pbsbp1∆-infected erythrocytes. Actin-based junctional complexes were displayed as individual clusters by the labeled TMOD in the STORM images, and the cluster densities and distances between adjacent clusters of infected RBCs were calculated. Additionally, rodent malaria models (BALB/c mice) and experimental cerebral malaria models (C57BL/6 mice) were employed to monitor the growth of Pbsbp1∆ and WT parasites during the intraerythrocytic stage and their capacity to induce cerebral malaria in mice. ResultsPbSBP1 may participate in the remodeling of infected erythrocytes through direct or indirect interaction with the erythrocyte cytoskeletal protein 4.1R. Microfluidic assays revealed that the deformability of erythrocytes infected with Pbsbp1∆ parasites was significantly enhanced compared to those infected with WT parasites. STORM imaging further demonstrated that the ultrastructure of the erythrocyte cytoskeleton in Pbsbp1∆-infected cells was altered relative to that in WT-infected erythrocytes. The distances between nearest neighbors of clusters had a tendency to increase while the cluster densities were decreased in Pbsbp1∆-infected RBCs compared to WT-infected RBCs. Subsequent phenotypic analysis indicated that the growth rate of Pbsbp1∆ parasites during the intraerythrocytic stage was significantly slower than that of WT parasites, and their ability to induce cerebral malaria in mice was also attenuated. These findings suggest that PbSBP1 is involved in the remodeling of the erythrocyte membrane skeleton, likely through its direct or indirect interaction with protein 4.1R, thereby regulating the deformability of infected erythrocytes and influencing the pathogenicity of the blood-stage parasites. ConclusionThis study establishes a role for PbSBP1 in host erythrocyte remodeling and parasite virulence, providing new research strategies for the prevention and treatment of malaria.

Objective:To investigate the efficacy and safety of transurethral incision for the treatment of ureterocele in infants.Methods:A retrospective analysis of 28 cases of ureterocele admitted from March 2012 to May 2023 were reviewed, all of which were less than 1 year old, 16 male and 12 female, with an average age of(5.7±3.5)months. The ureterocele was located on the left side in 8 cases, on the right side in 15 cases, and bilaterally in 5 cases. There were 12 cases of single system ureterocele, of which 7 cases were unilateral and 5 cases were bilateral. Duplex system ureterocele was observed in 16 cases, all of which were unilateral. Clinical manifestations: urinary tract infection in 13 cases, 11 cases of ureterocele or hydronephrosis and ureteral dilation were found during antenatal examination, and 4 cases of ureterocele were found after birth. Urological ultrasound, intravenous pyelography(IVP) and voiding cystourethrography(VCUG) were performed in all children, and 17 cases underwent magnetic resonance urolography (MRU), and confirm the diagnosis of ureterocele preoperatively. All of the cases were performed the transurethral incision.The ureterocele was punctured and incised 1-2 mm at the base of the bulge, and 2-4 points were punctured according to the bulge atrophy. Bilateral ureteroceles were punctured and incised simultaneously. Postoperative urine routine test, urinary tract color ultrasound and VCUG were performed to determine if there is urinary tract infection, hydronephrosis, ureteral dilation and bulging, and whether a second surgery is needed.Results:All operations were conducted successfully. The intraoperative bleeding was less than 3 ml and no intraoperative complications. The operative time was (28.4±10.3) min. The median postoperative follow-up was 34 (32, 36) months. Six cases underwent postoperative VCUG examination. Eleven children were recovered well with single systemic ureterocele. One child developed grade Ⅳ vesicoureteral reflux(VUR)and combined with bladder diverticulum, and ureterocele underwent open diverticulotomy and ureteral reimplantation six months after surgery. Nine children were recovered well with duplex systemic ureterocele. Six cases of children developed infection, of which 2 cases had an infection once within one month after TUI, and the other four cases still had intermittent infections after six months and VCUG was performed, and one case showed grade Ⅲ VUR of the lower ureter, which was observed conservatively, while the other three cases had enlarged cysts but no VUR, and upper heminephrectomy was performed, and the patients recovered well after surgery. Except for these 6 exceptions, in another case, after ten years of follow-up, the ureterocele became larger but no VUR, and the results were good after a second transurethral incision. There was no significant difference in the postoperative infections, new VUR cases, and secondary surgeries between the two groups.Conclusions:Transurethral incision has good surgical effect on children with single system ureterocele and duplex system ureterocele, and has advantages of easy operation, less trauma, safety and effectiveness, and few complications. It deserves to be recommended as the treatment of choice, especially for infants and young children.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Readiness for Hospital Discharge(RHD)refers to a multidimensional assessment of a patient's ability to transition safely from hospital to home,encompassing physiological stability,psychological preparedness,and social support adequacy.For patients requiring Home Nutrition Support(HNS),discharge readiness is particularly critical due to their heightened need for post-discharge specialized care,which significantly influences long-term recovery and quality of life.This paper reviews the concept,influencing factors,and unmet needs of RHD in patients with HNS and proposes targeted strategies to enhance discharge preparedness.By addressing gaps in current practices,we aim to optimize RHD in this vulnerable population and provide clinicians with evidence-based guidance for developing effective discharge plans.

Iodine speciations in aquatic environments are affected by dissolved oxygen,redox potential,microbial activity,organic matter decomposition,light reaction,etc.Accurate quantification of iodine speciation can not only help to understand the geochemical cycle of iodine,but also help to trace and study environmental processes.Based on the combination of ion chromatography(IC)and inductively coupled plasma mass spectrometry(ICP-MS),a rapid and sensitive method was established for determining the speciations of iodine in environmental water samples including seawater,river water,lake water,rainwater,groundwater,etc.The results presented here showed that IO3?and I?in seawater were quickly separated and measured within 120 s when using guard column AG22 and 8 mmol/L(NH4)2CO3 as the mobile phase.While for lake water,river water and precipitation samples with high soluble organically bond iodine(SOI),an AS22 separation column(250 mm×4 mm)connected with a guard column and using 50 mmol/L(NH4)2CO3 as mobile phase could effectively separate unknown SOI from IO3? to achieve accurate quantification of IO3?.For accurate correction of iodine measurement signal fluctuations,133Cs was directly added to the(NH4)2CO3 mobile phase as an internal standard.The SOI content was calculated by the total iodine concentrations minus the sum of IO3?and I?.The precision of the established iodine speciation analytical method was better than 3.5%,and the standard addition experiment showed that the analytical method was accurate.When the injection volume was 25 μL,the detection limits were 0.011?0.025 μg/L for IO3? and 0.023?0.031 μg/L for I?,respectively.The method was successfully used to analyze IO3?,SOI and I? in environmental water samples,such as seawater,river water,rainwater and groundwater.
