Objective: To validate the performance of the Procleix UltrioPlex E assay (Grifols, Spain) on the Procleix Panther automated nucleic acid detection platform, which employs the TMA method to simultaneously detect HIV-1/HIV-2/HCV/HBV/HEV viruses, and to evaluate its value for screening transfusion-associated infectious diseases. Methods: In accordance with the requirements of ISO15189"Application of the Guidelines for the Accreditation of Quality and Capabilities of Medical Laboratories in the Field of Molecular Diagnostics (CNAS-CL02-A009: 2018)", "Guidelines for Performance Validation of Molecular Diagnostic Testing Procedures (CNAS-GL039: 2019)", and the "Technical Operating Procedures for Blood Banks (2019 Edition)", this study validated the reagent's performance in terms of analytical sensitivity validation, performance consistency validation, interference resistance, and cross-contamination resistance. Results: Probit analysis revealed that the 95% detection limits (95% confidence interval) for HBV, HCV, HIV, and HEV were 2.0 IU/mL, 1.5 IU/mL, 18.0 IU/mL and 3.7 IU/mL, respectively, which were consistent with the minimum detection limits stated in the kit's package insert and were comparable to the Procleix Ultrio Elite kit. Both kits were used to test the performance validation serum plate simultaneously, yielding results consistent with the serum plate (Kappa=1), indicating stable performance. Detection of medium-and low-concentration lipemia and weakly positive hemolysis samples demonstrated good interference resistance. Cross-contamination performance validation showed that the kit exhibited excellent cross-contamination resistance. Conclusion: The Procleix UltrioPlex E nucleic acid detection kit enables combined detection of HIV-1, HIV-2, HCV, HBV, and HEV, allowing single-test screening for multiple viruses in donor blood. The kit's analytical performance is stable and meets basic laboratory requirements, making it suitable for screening transfusion-associated infectious diseases in blood banks.

ObjectiveTo observe the effect of functional pelvic floor muscle training on pelvic floor muscle function, incontinence symptoms and quality of life in female patients with stress urinary incontinence (SUI). MethodsFrom February, 2024 to July, 2025, 40 female patients with SUI were recruited from Beijing Bo'ai Hospital and advertisements. They were randomly divided into control group (n = 20) and experimental group (n = 20). The control group received conventional pelvic floor muscle contraction and relaxation training, and the experimental group received functional pelvic floor muscle contraction and relaxation training, for eight weeks. The data of pelvic floor muscle strength, pelvic floor muscle surface electromyography (sEMG), 1-hour urine pad test and Incontinence Quality of Life questionnaire (I-QOL) were collected before and after training. The compliance rate was counted after training. ResultsOne case dropped down in the control group and three cases dropped down in the experimental group. After treatment, the pelvic floor muscle strength increased in both groups (|Z| > 3.317, P < 0.01), the pre-resting average value, sustained contraction average value and durable contraction average value of sEMG improved in the control group (|t| > 2.731, P < 0.05), the mass of 1-hour urine pad significantly reduced (t > 9.215, P < 0.001) and the I-QOL score significantly increased (|t| > 13.229, P < 0.001) in both groups; compared with the control group, the pelvic floor muscle strength significantly increased (Z = -2.281, P = 0.023), the mass of 1-hour urine pad significantly reduced (t = 4.215, P < 0.001), the I-QOL score significantly increased (t = -4.501, P < 0.001), and the compliance rate significantly increased (Z = -2.798, P < 0.01) in the experimental group . ConclusionFunctional pelvic floor muscle training can significantly improve pelvic floor muscle strength, incontinence symptoms and quality of life in female patients with SUI.

Objective To evaluate the feasibility of intravesical instillation of urokinase and heparin sodium in the treatment of bladder clot irrigation.Methods This report discusses the diagnosis and treatment of three patients with bladder blood clot tamponade confirmed by abdominal and pelvic computed tomography(CT)scans enrolled from our hospital during Jun. to Sep. 2024, and discuss the relevant literature.Results A solution containing urokinase(20 000 IU)and heparin sodium(125 000 U)was instilled through a three-way catheter and retained for 30 minutes before drainage. Complete clot dissolution was achieved in all cases, with immediate relief of hypogastric distension and pain. Post-procedural CT showed restored bladder lumen patency. Hemoglobin levels decreased by 2-5 g/L without complications.Conclusion This preliminary trial demonstrated that intravesical instillation of urokinase-heparin provides a safe and effective minimally invasive alternative for bladder clot in irrigation cases.

OBJECTIVE To clarify the current development status of clinical pharmacist training bases and the pharmacist workforce in China， and to provide evidence for standardizing base construction and promoting the high-quality development of hospital pharmacy. METHODS Questionnaires were distributed to all clinical pharmacist training bases for urgently-needed health professionals and clinical pharmacist training bases under the Chinese Hospital Association that had been approved by the end of 2023 to collect data including base profiles and pharmacist staffing conditions. Expert teams carried out field investigations to verify the collected data. Descriptive statistical analyses were conducted on the quantity， type and regional distribution of training bases， and the influencing factors of pharmacist staffing in the bases were analyzed. RESULTS Field surveys were completed covering 297 training bases across 31 provincial-level administrative regions. Among the base hospitals， 87.88% were Grade A tertiary general hospitals， and 65.32% were located in provincial capitals. The eastern region had the largest number of bases （136， accounting for 45.79%）， followed by the western region （79， 26.60%）. Great disparities existed among provinces in terms of base quantity and hospital scale. The median proportion of pharmaceutical technical personnel in base hospitals was 4.05%， and the median number of clinical pharmacists per 100 hospital beds was 0.53. Both indicators reached the highest in the eastern region （0.57， 4.43%） and the lowest in the northeastern region （0.45， 3.01%）. A total of 3 627 full-time clinical pharmacists were employed in all surveyed bases， among whom 83.68% held clinical pharmacist training certificates， 35.43% possessed senior professional titles， and 78.19% had postgraduate or higher educational background. The total annual training capacity of the surveyed bases was 4 291 trainees， with obvious differences in annual training capacity across regions and provinces. Training specialties covered 19 specialized disciplines plus one general discipline， and no province could deliver training for all 20 specialties simultaneously. Multivariate Logistic regression analysis showed that geographic region exerte d a significant impact on the proportion of pharmaceutical technical personnel （≥4%） （ P ＜0.05）， while the approval time of training bases and hospital scale had significant effects on the number of clinical pharmacists per 100 beds （≥0.6） （ P ＜0.05）. CONCLUSIONS China’s clinical pharmacist training system has basically matured and taken initial shape. The distribution of clinical pharmacist training resources is generally consistent with regional population and economic development levels. However， the allocation of pharmaceutical staff and clinical pharmacists has not yet met national standards and clinical service demands.

OBJECTIVE To investigate the current status of quality management in clinical pharmacist training bases in China， and to provide references for the standardized development and improvement of these bases. METHODS A combined approach of questionnaire survey and on-site investigation was adopted， targeting the healthcare highly sought-after talent （clinical pharmacist） training bases in 31 provinces of China as well as the clinical pharmacist training bases affiliated with the Chinese Hospital Association. A training quality management evaluation index system consisting of 25 tertiary indicators was established. Investigations were conducted from two dimensions： structural quality of training and quality management of training processes. Data were statistically analyzed using descriptive statistical methods. RESULTS On-site investigations were completed for 297 clinical pharmacist training bases across the 31 provinces， among which 284 were affiliated with the Chinese Hospital Association and 271 were healthcare highly sought-after talent （clinical pharmacist） training bases. In terms of structural quality， the core indicator compliance rate for hospital-level training systems exceeded 80%， the rate of special fund utilization for designated purposes reached 80.13%， and the overall compliance rate for software and hardware facilities surpassed 88%. A total of 1 348 preceptors were employed across the training bases， among whom those with senior professional titles and full-time specialist clinical pharmacists as lead preceptors accounted for 62.91% and 94.36%， respectively. Regarding process quality， the compliance rate for “establishment of clinical practice teaching groups in accordance with regulations during clinical department rotations” was 85.19%， and 79.80% and 76.09% of the bases were found to implement strict confidentiality in theoretical examinations and meet the required scale of assessment cases， respectively. However， formal documents of corresponding training management regulations were formulated in only 57.91% of the bases， and the completeness and standardization rate of training manual completion was merely 47.47%. In addition， considerable disparities in quality management levels were observed among provinces， with issues in training process quality being particularly prominent. CONCLUSIONS The management system， hardware facilities， and preceptor staffing of clinical pharmacist training bases in China are relatively well-established， yet notable variations in quality management exist among training bases across different provinces.

ObjectiveTo investigate the antiviral efficacy of pegylated interferon α-2b （PEG-IFN-α-2b） in patients with HBV-related liver cirrhosis， to assess the safety and tolerability of this regimen， and to provide evidence-based medical evidence for optimizing the treatment strategies for patients with HBV-related compensated liver cirrhosis. MethodsA prospective study was conducted among 115 patients with HBV-related compensated liver cirrhosis and 114 patients with CHB who attended Third People’s Hospital of Taiyuan from January 2023 to March 2024. Treatment-naïve patients received PEG-IFN-α-2b monotherapy， while the patients once treated with nucleos（t）ide analogues （NAs） received PEG-IFN-α-2b add-on therapy. The patients with HBV-related compensated liver cirrhosis were followed up at baseline and at 12， 24， 36， and 48 weeks of treatment. Samples were collected from CHB patients at baseline and at the end of follow-up to assess virological indicators， routine blood test results， and liver function. The chi-square test was used for comparison of categorical data between groups； the independent samples t-test was used for comparison of normally distributed continuous data between two groups， and the one-way repeated measures analysis of variance was used for comparison among different time ponts within the same group，and the Bonferroni was applied for post-hoc pairwise comparisons； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the Friedman test was used for comparison across different time points within the same group， and the Nemenyi test was utilized for subsequent pairwise comparisons. The multivariate stepwise Logistic regression analysis was used to investigate the influencing factors for clinical cure. ResultsCompared with the CHB group， the HBV-related compensated liver cirrhosis group had a significantly higher mean age （43.50±9.97 years vs 40.90±8.16 years， t=2.160， P=0.032）， a significantly higher proportion of patients with hepatitis B e antigen at baseline （28.70% vs 15.79%， χ²=4.788， P=0.029）， and a significantly lower platelet level ［（178.67±55.07）×10⁹/L vs （194.93±55.79）×10⁹/L， t=2.217， P=0.028］. Compared with the CHB group at the end of follow-up， the HBV-related compensated liver cirrhosis group had significantly lower HBV surface antigen （HBsAg） clearance rate （10.38% vs 33.04%， χ²=14.988， P<0.001） and HBV surface antibody positive rate （0.00% vs 19.64%， χ²=21.041， P<0.001）. Compared with the CHB group at the end of follow-up，the HBV-related compensated liver cirrhosis group had significantly lower aminotransferase levels ［ALT： 31.00（19.00～47.50） U/L vs 40.00（27.00～57.00） U/L， Z=2.433， P<0.05； AST： 31.00（23.00～45.50） U/L vs 37.00（25.00～52.00） U/L， Z=1.963， P<0.05］， but significantly higher level of white blood cells （WBC） ［（4.02±1.56）×10⁹/L vs （3.59±1.24）×10⁹/L， t=2.272， P<0.05］， neutrophils ［（2.39±1.17）×10⁹/L vs （1.87±0.94）×10⁹/L， t=3.284， P<0.05］， and platelets ［（143.93±68.10）×10⁹/L vs （121.88±49.72）×10⁹/L， t=2.588， P<0.05］. A lower level of HBsAg （OR=0.997， 95%CI： 0.996　—　0.999， P<0.001） and previous treatment with NAs （OR=5.889， 95%CI： 2.195　—　17.330， P<0.001） were positive predictive factors for clinical cure， while liver cirrhosis （OR=0.177， 95%CI： 0.063　—　0.470， P<0.001） was a negative predictive factor for clinical cure. During follow-up， no patients experienced acute decompensation or progression to hepatocellular carcinoma， and the main adverse events included fever， fatigue， reductions in WBC and platelets， weight loss， alopecia， and thyroid dysfunction. In the subgroup analysis of HBV-related compensated liver cirrhosis， in both the treatment-naïve patients and the patients previously treated with NAs， there was a significant reduction in HBsAg level from baseline to week 36 of treatment ［treatment-naïve： 99.25 （5.87　—　1 212.35） IU/mL vs 403.47 （36.94　—　2 569.02） IU/mL， P<0.05； previously treated with NAs： 205.94 （14.00　—　737.80） IU/mL vs 427.03 （65.64　—　1 552.65） IU/mL， P<0.05］ and week 48 of treatment ［treatment-naïve： 85.45 （0.58　—　827.56） IU/mL vs 403.47 （36.94　—　2 569.02） IU/mL， P<0.05； previously treated with NAs： 45.28 （0.16　—　267.27） IU/mL vs 427.03 （65.64　—　1 552.65） IU/mL， P<0.05］. There were significant increases in the levels of aminotransferases during treatment， as well as significant reductions in the levels of WBC， neutrophils， platelets， and hemoglobin （all P<0.05）. ConclusionAlthough a finite course of PEG-IFN-α-2b therapy has achieved a relatively low rate of clinical cure in the treatment of HBV-related compensated liver cirrhosis， it can still significantly reduce the level of HBsAg， and this treatment regimen has good safety and tolerability， without accelerating disease progression.

POEMS syndrome is a rare condition associated with plasma cell disorders， and it often involves multiple systems and has diverse clinical manifestations. This article reports two cases of POEMS syndrome with hepatosplenomegaly as the initial manifestation. During the course of the disease， the patients presented with lower limb weakness， hepatosplenomegaly， lymph node enlargement， ascites， hypothyroidism， positive M protein， and skin hyperpigmentation， and ¹⁸F-FDG PET-CT imaging revealed bone lesions mainly characterized by osteolytic changes and plasma cell tumors. There was an increase in the serum level of vascular endothelial growth factor. The patients were finally diagnosed with POEMS syndrome， and the symptoms were relieved after immunomodulatory treatment.

Through network pharmacology and molecular docking technology, combined with in vitro experiment verification, we explored the mechanism of action of Porana racemosa Roxb. (PRA) in the treatment of rheumatoid arthritis (RA), and provided a modern pharmacological basis for the treatment of RA by PRA. The potential target of chemical components in the analyzed moth rattan was predicted by Swiss Target Prediction database; OMIM, GeneCards, TTD and Disgenet databases were used to search the disease targets of RA; the protein interaction (PPI) network and medicine-composition-target network were constructed using STRING database and Cytoscape software; GO (gene ontology) functional enrichment and KEGG (kyoto encyclopedia of genes and genomes) pathway analysis were carried out using DAVID database, and molecular docking software was used to dock the potentially active ingredients of PRA and core targets; finally, MH7A cells were selected for cell viability, scratch healing and mRNA expression level analysis of key genes to explore the effects of PRA and their potentially active ingredients on the proliferation, migration and apoptosis of MH7A cells. In this study, a total of 628 potentially active ingredient targets, 1 890 RA targets and 235 intersection targets were identified. It was screened that the potentially active ingredients of RA treatment by PRA were ethylcaffeate, N-p-coumaroyltyramine, 9,12,15-octadecatrienoic acid, methyl ester and so on, and the core targets involved tumor necrosis factor (TNF), matrix metalloproteinase 9 (MMP9), prostaglandin-endoperoxide synthase 2 (PTGS2) and so on. 1 200 GO entries and 166 KEGG pathway entries were obtained from the enrichment analysis; molecular docking results showed that N-p-coumaroyltyramine and ethylcaffeate had good binding activity with TNF, MMP9, cysteine-aspartate protease 3 (CASP3), PTGS2, B-cell lymphoma 2 (BCL2) proteins. In vitro experiments showed that PRA, ethylcaffeate and N-p-coumaroyltyramine could inhibit the proliferation, migration and invasion of MH7A cells, up-regulate the expression of apoptosis-related gene CASP3 mRNA, and down-regulate the expression of MMP9, PTGS2 and BCL2 mRNA, and it can also down-regulate the expression of phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT) mRNA and PI3K and p-AKT proteins. This study preliminarily revealed that the treatment of RA by PRA may be related to proliferation, migration, invasion, apoptosis and regulation of PI3K/AKT signaling pathway.

Background During pregnancy, negative emotions such as anxiety and depression may induce cortisol disruption. Cortisol can be transmitted to the fetus through the placental barrier, thereby affecting the neurodevelopment of the offspring. Objective To investigate the relationship between placental cortisol, maternal depression during pregnancy, and neurodevelopment of 3-month-old infants. Methods From September 2022 to September 2023, 171 pregnant women ordered routine prenatal checks at the obstetrics outpatient department of a tertiary hospital in Ningxia were selected using a prospective cohort design. After providing informed consent, these women participated in a questionnaire survey that covered general individual characteristics, prenatal depression, and sleep quality. At birth, placental samples were collected to measure cortisol levels using ELISA kits. Follow-up assessments on the neurodevelopmental of 3-month-old infants were conducted using the Warning Sign for Children Mental and Behavioral Development. LASSO regression analysis was conducted to screen the influencing factors of depression during pregnancy. Huber regression analysis was then applied to assess potential linear relationship between depression during pregnancy and placental cortisol levels. Log-binomial regression was used to analyze the linear relationships between cortisol levels and neurodevelopmental delay in 3-month-old infants. Additionally, a mediation effect model was fitted using R 4.3.3 to assess possible mediating role of cortisol in the association between prenatal depression and neurodevelopmental delay in 3-month-old infants. Results The positive rate of prenatal depression was 33.33%. Nine factors affecting prenatal depression were identified by LASSO regression, including rural residence, high school education or above, extroverted personality characteristics, moderate early pregnancy reactions, baby sex expectation, prenatal anxiety, family dysfunction, exposure to stressful life events during pregnancy, and moderate prenatal sleep quality. The Huber regression model showed a positive linear correlation between prenatal depression and placental cortisol (P<0.05). With or without controlling confounding factors, the results of log-binomial regression modeling showed that cortisol levels were associated with a reduced risk of neurodevelopmental delay in 3-month-old infants (crude model: RR=0.988, 95%CI: 0.9768, 0.9996, P＜0.05; adjusted model: RR=0.988, 95%CI: 0.9764, 0.9993, P＜0.05). A mediating effect of placental cortisol between prenatal depression and the risk of neurodevelopmental delay in 3-month-old offspring was found statistically significant (P=0.045), accounting for 67.0% of the total effect. Conclusion Prenatal depression is associated with elevated placental cortisol levels, and higher cortisol levels are found to be related to a lower risk of neurodevelopmental delay in infants. Placental cortisol mediates the relationship between prenatal depression and infant neurodevelopment.
