Objective:To analyze the human immunodeficiency virus (HIV) screening status and the resulting residual risk (RR) among blood donors across 17 provincial blood centers in China.Methods:This study used a cross-sectional study. Data on HIV infection markers per 100 000 first-time donors (FD) and repeat donors (RD) from January 2015 to December 2024 were extracted from the National Blood Establishment Performance Comparison Information Management System. Questionnaires were used to collect each center′s HIV screening strategy, algorithm, serological test (ST) kit manufacturers, gray-zone setting for ST, and nucleic acid test (NAT) modality, method, and platform. The incidence-window-period model was used to calculate the residual risk for first-time donors (RR FD), repeat donors (RR RD), and total donors (RR TD) at each center. Horizontal and vertical analysis of RR FD, RR RD, and RR TD across centers and years were performed. Results:All 17 centers applied the same HIV screening strategy which was two rounds of ST followed by one round of NAT. Eight of them operated a single screening algorithm, six employed two algorithms and three used three. Eleven centers used both imported and domestic ST kits, five relied on domestic ST kits only, and one used imported ST kits only, while four centers never set a grey zone for ST throughout the decade. For NAT modalities, eight centers adopted both individual nucleic acid test (ID-NAT) and minipool nucleic acid test (MP-NAT), eight used MP-NAT only and one used ID-NAT only. Seven centers combined transcription mediated amplification (TMA) and polymerase chain reaction (PCR), nine used PCR only and one used TMA only, and fourteen centers ran both imported and domestic NAT systems, two used imported systems only and one used a domestic system only. Over the ten-year period, the mean RR FD across the centers ranged from 2.22 to 12.33 per 10 6 person-years, RR RD from 0.83 to 3.29 per 10 6 person-years and RR TD from 1.59 to 9.29 per 10 6 person-years, with center Z4 consistently showing the lowest values for all three metrics and center U4 recording the highest RR FD and RR TD, while center D2 had the highest RR RD. In 2024 compared with 2015, eleven centers achieved a lower RR FD and ten centers achieved lower RR RD and RR TD. The RR FD and RR TD of centers W2 and U4 displayed pronounced fluctuations and an upward trend in recent years. Conclusions:The 17 provincial blood centers maintain consistent HIV screening strategies, while demonstrating variations in screening algorithm, ST kit manufacturers, NAT modalities, methods, and platform. And the RR FD, RR RD, and RR TD differ across centers. Although most centers show declining trend in RR over the ten-year period, some centers exhibite data fluctuations with a rising trend, suggesting potential for further optimization of HIV screening protocols.

Early screening, diagnosis, and intervention for congenital muscular torticollis (CMT) in infants are crucial for improving clinical outcomes. However, in China, limited awareness of CMT among child healthcare institutions and caregivers, as well as inconsistent professional standards among rehabilitation personnel, pose significant challenges to the effective diagnosis and management of CMT. The "Physical therapy management of congenital muscular torticollis: a 2024 evidence-based clinical practice guideline from the American Physical Therapy Association Academy of Pediatric Physical Therapy" includes 17 action statements, primarily addressing the prevention, identification, assessment, and intervention of CMT. This guideline is expected to facilitate early detection of CMT in infants, enhance the treatment capabilities of physical therapists, and improve clinical outcomes. This article provides an interpretation of the guideline in the context of the current status of CMT diagnosis and management in China, aiming to offer a reference for improving the ability of primary child healthcare providers and physical therapists to recognize and manage CMTropriately.

Objective: To investigate the effect of the AML1-ETO (AE) fusion gene on the biological function of U937 leukemia cells by establishing a leukemia cell model that induces AE fusion gene expression. Methods: The doxycycline (Dox) -dependent expression of the AE fusion gene in the U937 cell line (U937-AE) were established using a lentivirus vector system. The Cell Counting Kit 8 methods, including the PI and sidanilide induction, were used to detect cell proliferation, cell cycle-induced differentiation assays, respectively. The effect of the AE fusion gene on the biological function of U937-AE cells was preliminarily explored using transcriptome sequencing and metabonomic sequencing. Results: ①The Dox-dependent Tet-on regulatory system was successfully constructed to regulate the stable AE fusion gene expression in U937-AE cells. ②Cell proliferation slowed down and the cell proliferation rate with AE expression (3.47±0.07) was lower than AE non-expression (3.86 ± 0.05) after inducing the AE fusion gene expression for 24 h (P<0.05). The proportion of cells in the G(0)/G(1) phase in the cell cycle increased, with AE expression [ (63.45±3.10) %) ] was higher than AE non-expression [ (41.36± 9.56) %] (P<0.05). The proportion of cells expressing CD13 and CD14 decreased with the expression of AE. The AE negative group is significantly higher than the AE positive group (P<0.05). ③The enrichment analysis of the transcriptome sequencing gene set revealed significantly enriched quiescence, nuclear factor kappa-light-chain-enhancer of activated B cells, interferon-α/γ, and other inflammatory response and immune regulation signals after AE expression. ④Disorder of fatty acid metabolism of U937-AE cells occurred under the influence of AE. The concentration of the medium and short-chain fatty acid acylcarnitine metabolites decreased in cells with AE expressing, propionyl L-carnitine, wherein those with AE expression (0.46±0.13) were lower than those with AE non-expression (1.00±0.27) (P<0.05). The metabolite concentration of some long-chain fatty acid acylcarnitine increased in cells with AE expressing tetradecanoyl carnitine, wherein those with AE expression (1.26±0.01) were higher than those with AE non-expression (1.00±0.05) (P<0.05) . Conclusion: This study successfully established a leukemia cell model that can induce AE expression. The AE expression blocked the cell cycle and inhibited cell differentiation. The gene sets related to the inflammatory reactions was significantly enriched in U937-AE cells that express AE, and fatty acid metabolism was disordered.

Objective:To evaluate the effect of esketamine combined with ultrasound-guided dorsal penile nerve block (DPNB) on negative postoperative behavioral changes (NPOBCs) in pediatric patients undergoing circumcision under general anesthesia.Methods:One-hundred and ninety-five pediatric patients, aged 4-8 yr, with body mass index of 10-35 kg, of American Society of Anesthesiologists Physical Status classificationⅠ or Ⅱ, undergoing elective circumcision under general anesthesia, were selected and divided into 3 groups ( n=65 each) using a random number table method: esketamine group (group E), DPNB group (group D) and esketamine combined with DPNB group (group ED). Propofol 1.5 mg/kg was intravenously injected, and the patients were admitted to the operating room after consciousness disappeared in the 3 groups. Esketamine 0.5 mg/kg was intravenously injected in E and ED groups, and the equal volume of normal saline was given in group D. D and ED groups underwent bilateral DPNB with 0.25 % ropivacaine 0.15 ml/kg under ultrasound guidance, with the maximum total amount of the drug not exceeding 10 ml. Fentanyl 1.0 μg/kg and propofol 2.0 mg/kg were intravenously injected prior to the skin incision in the three groups. If intraoperative body movement occurred, propofol 10 mg was added, which could be repeated. The occurrence of intraoperative body movement, respiratory depression and amount of propofol added was recorded. When postoperative pain (FLACC score >4) occurred, flurbiprofen 1 mg/kg was intravenously injected for analgesia, and the usage of flurbiprofen was recorded. When emergence agitation(PEAD score>10) occurred, propofol 1 mg/kg was intravenously injected for sedation, and the occurrence of emergence agitation was recorded. Parents were followed up by telephone at 1, 7 and 30 days postoperatively to assess the occurrence of NPOBCs using the PHBQ scale. Results:Fifty-six patients in group E and 59 patients in D and ED groups finally completed the study.Compared with group E, the incidence of intraoperative body movement was significantly decreased, the amount of additional propofol was reduced, the emergence agitation score, incidence of emergence agitation and severe agitation and usage rate of postoperative flurbiprofen were decreased, and the incidence of separation anxiety at 7 and 30 days postoperatively was decreased in D and ED groups, and the incidence of intraoperative respiratory depression was significantly decreased, and the incidence of NPOBCs at 7 and 30 days postoperatively was decreased in group ED ( P<0.05). Compared with group D, the incidence of intraoperative respiratory depression was significantly decreased, the amount of additional propofol was decreased, the usage rate of postoperative flurbiprofen and incidence of sleep anxiety at 1 day postoperatively were decreased ( P<0.05), and no significant change was found in the incidence of NPOBCs at each time point after operation in group ED ( P>0.05). Conclusions:Esketamine combined with ultrasound-guided DPNB can reduce the occurrence of NPOBCs in pediatric patients undergoing circumcision under general anesthesia.

Objective: To evaluate the safety of simultaneous administration of quadrivalent influenza split virion vaccine and 23-valent pneumococcal polysaccharide vaccine in adults aged 60 years and older. Methods: From November 2021 to May 2022, eligible participants aged 60 years and older were recruited in Taizhou City, Jiangsu Province, China, and a total of 2 461 participants were ultimately enrolled in this study. Each participant simultaneously received one dose of quadrivalent influenza split virion vaccine and one dose of 23-valent pneumococcal polysaccharide vaccine. The safety was observed within 28 days after vaccination. Safety information was collected through voluntary reporting and regular follow-ups. Results: All 2 461 participants completed the simultaneous administration of both vaccines and the safety follow-ups for 28 days after vaccination. The mean age of the participants was (70.66±6.18) years, with 54.61% (1 344) being male, and all participants were Han Chinese residents. About 22.51% (554) of the participants had underlying medical conditions. The overall incidence of adverse reactions within 0-28 days after simultaneous vaccination was 2.07% (51/2 461), mainly consisting of Grade 1 adverse reactions [1.83% (45/2 461)], with no reports of Grade 4 or higher adverse reactions or vaccine-related serious adverse events. The incidence of local adverse reactions was 0.98% (24/2 461), primarily presenting as pain at the injection site [0.93% (23/2 461)]. The incidence of systemic adverse reactions was 1.42% (35/2 461), with fever [0.85% (21/2 461)] being the main symptom. In the group with underlying medical conditions and the healthy group, their overall incidence of adverse reactions was 2.53% (14/554) and 1.94% (37/1 907), respectively. The incidence of local adverse reactions in the two groups was 1.62% (9/554) and 0.79% (15/1 907), respectively, and the incidence of systemic adverse reactions was 1.44% (8/554) and 1.42% (27/1 907), respectively, with no statistically significant differences between them (all P>0.05). Conclusion: It is safe for adults aged 60 years and older to receive quadrivalent influenza split virion vaccine and 23-valent pneumococcal polysaccharide vaccine at the same time.

OBJECTIVE To establish HPLC characteristic chro matogram of Jianpi yifei biyan prescription standard decoction ， to select the quality control index components and determine their contents. METHODS HPLC method combined with Similarity Evaluation System of TCM Chromatographic Fingerprint （2004 edition）were used to establish the characteristic chromatogram of 10 batches of Jianpi yifei biyan prescription standard decoction ；the similarity evaluation and common peaks identification were also carried out. Using common peak area of characteristic chromatogram as variables ，SPSS 26.0 software and SIMCA 14.1 software were used to perfor m cluster analysis （CA），principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA）；differential components with variable important i n pro jection（VIP）value greater than 1.5 were screened；the contents of cimifugin and differential components were determined by the same method. RESULTS A total of 24 common characteristic peaks were identified ， and the similarities of 10 batches of samples were higher than 0.960；eight characteristic peaks were identified by comparison with reference substance. CA and PCA results revealed that the samples were classified into 3 categories.OPLS-DA analysis showed that 3 components with VIP value greater than 1.5， which were prim-O-glucosylcimifugin （peak 2），calycosin 7-O-β-D-glucopyranoside （peak 4） and 5-O-methylvisammioside （peak 6） in descending order. The linear ranges of prim- O- glucosylcimifugin，calycosin 7-O-β-D-glucopyranoside，cimifugin and 5-O-methylvisammioside were 0.010 7-0.213 0，0.007 8- 0.156 0，0.008 0-0.160 0，0.009 8-0.195 0 μg（r＞0.999），respectively. RSD values of precision ，repeatability and stability tests （24 h） were all less than 2％. Average recoveries were 105.98％（RSD＝1.75％，n＝6），98.06％（RSD＝3.87％，n＝6），96.38％（RSD＝ 4.03％ ，n＝6） and 104.17％（RSD＝1.27％ ，n＝6）. The contents of the above 4 components in 10 batches of samples were 12.12-18.87，3.86-6.40，3.10-4.27 and 11.17-15.79 μ g/mL，respectively. CONCLUSIONS The established HPLC characteristic chromatographic method is stable and feasible ，it can be used for the quality control of Jianpi yifei biyan prescription standard decoction. Prim- O-glucosylcimifugin，calycosin 7-O-β-D-glucopyranoside，cimifugin and 5-O-methylvisammioside can be used as the index components for quality control of the standard decoction.
