Objective: To summarize strategies for improving childhood hypertension, so as to provide evidencebased recommendations for poliymaking and practice childhood hypertension management in China. Methods: From March to April 2024, child health stakeholders from five districts in Hangzhou were selected using a combination of stratified and convenience sampling methods. Data were analyzed using a groundedtheory approach. During the indepth interview phase, six policymakers were interviewed. Focus group discussions were conducted with school administrators, healthcare providers, and parents, comprising a total of 62 participants. Results: Through threelevel coding, 116 initial categories were identified(e.g., "trend of younger age" "difficulty in behavior change"), 35 main categories (e.g., "higher incidence compared to the past" "caused by comprehensive influencing factors"), and 12 core categories (e.g., "epidemic status" "influencing factors"). Finally, the cognitive status, problem analysis, and management strategies of children hypertension were constructed. Conclusion Effective prevention and control of childhood hypertension requires coordinated efforts among governments, schools, families, and society to establish a comprehensive management system, with dynamic monitoring and evaluation to optimize policy implementation.

Objective: To analyze the regulatory effect of Atractylodes macrocephala Koidz. extract on the immune function of mice, so as to provide a reference for the study of the mechanism of Atractylodes macrocephala Koidz. regulating immune function. Methods: Forty-eight SPF healthy male ICR mice were randomly divided into control group and low (0.5 g/kg), medium (2.0 g/kg), and high (4.0 g/kg) dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day. The delayed allergy test was performed for 28 consecutive days. Sixty SPF healthy male ICR mice were randomly divided into a control group, polyinosinic acid injection group (model group), and low, medium, and high dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day for 14 consecutive days. On days 13 and 14 of administration, the mice in the model group and each dose group were intraperitoneally injected with sterile polyinosinic acid solution to perform the immunosuppressive experiment induced by polyinosinic acid. The mouse ear pieces were weighed, and the thymus and spleen of the mice were weighed and stained with HE to calculate the pathological scores. Peripheral blood was collected for blood cell detection and T cell classification. Results: Mice in each group had normal feeding, activity, and growth status, and no abnormality was observed. In the delayed allergy test, compared with the control group, the degree and rate of ear swelling in the low, medium and high dose groups were higher, the white blood cell count in the medium dose group was higher, and the absolute values of lymphocytes in the low and medium dose groups were higher (all P<0.05). Compared with the control group, the pathological scores of the thymus and spleen in the model group were higher (both P<0.05). In the immunosuppressive experiments in mice induced by polyinosinic acid, compared with the model group, the pathological score of the thymus in the high dose group was lower (P<0.05), and the boundary between the thymus cortex and medulla was improved. Conclusions Atractylodes macrocephala Koidz. extract can increase the degree of ear swelling and peripheral blood white blood cell count in mice. High dose of Atractylodes macrocephala Koidz. extract can improve the thymus injury induced by polyinosinic acid, and has an immunomodulatory effect.

Objective: To analyze the results of national external quality assessment (EQA) for transfusion compatibility test from 2018 to 2023, with the aim of providing references for improving laboratory testing quality and ensuring the safety of clinical blood transfusion. Methods: Three EQA programs were conducted annually, each distributing 22 quality assessment samples. Participating transfusion laboratories were required to complete testing within specified deadlines and to submit results along with documentation of testing methodologies, reagents, and equipment used. National Center for Clinical Laboratories (NCCL) conducted statistical analysis of laboratory results, evaluated testing outcomes and related circumstances, and provided feedback to participating laboratories. EQA data from transfusion laboratories across China from 2018 to 2023 were collected and systematically analyzed. Results: From 2018 to 2023, the qualification rates for all five items (ABO forward typing, ABO reverse typing, Rh blood group typing, antibody screening, and cross-matching) were 67.59%, 77.11%, 77.38%, 72.78%, 79.96%, and 85.16%, respectively. The mean qualification rates for ABO forward typing, ABO reverse typing, RhD blood group typing, antibody screening, and cross-matching over the past six years were 96.25%±0.59%, 90.45%±4.52%, 96.05%±0.71%, 90.88%±2.86%, and 88.34%±3.48%, respectively. The qualification rates in 2019, 2020, 2022, and 2023 all showed a stable trend of "blood stations>tertiary hospitals>secondary hospitals". The mean qualification rate of laboratories in secondary hospitals from 2018 to 2023 was significantly lower than those of laboratories in tertiary hospitals and blood stations (P<0.05), while no significant difference was observed between laboratories in tertiary hospitals and blood stations (P>0.05). The micro column agglutination method was the most widely used in all five tests. In the four test items, namely ABO forward typing, ABO reverse typing, antibody screening, and cross-matching, there was a statistically significant difference in the qualification rate of micro column agglutination method compared to other methods (P<0.05). There was a statistical difference in the qualification rate between manual and automated detection using micro column agglutination method in the cross-matching tests (P<0.05), whereas no significant difference was noted for the other test items (P>0.05). Conclusion: From 2018 to 2023, the number of laboratories participating in EQA activities has been increasing year by year, and the qualification rate has shown an overall upward trend. The type of laboratory is a key factor affecting the qualification rate, and the testing capabilities of some laboratories still need to be improved. The micro column agglutination method is widely used in transfusion compatibility tests. The established EQA program effectively monitors quality issues in laboratories, drives continuous improvement, and ensures sustained enhancement of testing standards to safeguard clinical blood safety.

Objective: To explore the association between waist circumference and beverage consumption behaviors among junior high school students, so as to provide a theoretical basis for improving their nutritional status. Methods: Using a multi stage cluster random sampling method, 1 611 junior high school students aged 13-15 years from Yushan, Yanshan, Yiyang, and Wannian counties in Shangrao City, Jiangxi Province, were selected for a survey in September 2021 through questionnaires and waist circumference measurements. Stratified analyses were conducted by sex, t-test and analysis of variance (ANOVA) were used to compare waist circumference across groups, and analysis of covariance (ANCOVA) was applied to examine the associations between different types of beverage consumption and waist circumference. Results: Boarding students had significantly greater average waist circumference than day students[boys:(71.86±9.24, 69.69±12.19)cm；girls:(66.53±13.30, 64.63±11.90)cm； t =2.69, 2.08, both P < 0.05 ]. Among boys, waist circumference differed significantly by vigorous physical[vigorous physical:(69.71±9.53)cm; non vigorous exercise:(71.53±12.99)cm]( t=-2.31, P <0.05). Boys waist circumference also differed significantly by consumption frequency (high and medium,low,none) of milk containing beverages[(71.83±7.40, 69.92±9.98, 72.29±13.90)cm], functional beverages[( 73.36± 11.87, 65.97±10.46, 70.71±10.55)cm] and purified water beverages[(69.36±10.87, 71.93±12.15, 71.50±10.09)cm]( F =4.06, 5.93, 4.85, all P <0.05). Girls waist circumference also differed significantly by consumption frequency (high and medium,low,none) of milk containing beverages[(68.81±5.55, 66.59±13.02, 65.36±11.69)cm, F=9.67, P <0.01]. After controlling for the confounding variables, ANCOVA results indicated that the consumption of milk containing beverages, functional beverages and Purified water beverages were significantly associated with waist circumference of boys ( F =3.79, 5.26, 5.08, all P < 0.05 ). Milk containing beverages were significantly associated with waist circumference of girls ( F=4.17, P <0.05). Conclusion The consumption frequency of milk containing beverages and functional beverages by junior high school students is positively correlated with their waist circumference.

【Objective】 To perform pre-transfusion examination and major crossmatch test using CD47 anti-idiotypic antibody (CD47 AID) (method 1) and reagent lack of anti-IgG4 anti-human globulin(method 2) in patients treated with CD47 monoclonal antibodies, and evaluate the feasibility of method 1 by comparing the transfusion efficacy of patients after cross matching with two methods. 【Methods】 Post-drug samples were collected from 18 clinical subjects treated with CD47 monoclonal antibody in our hospital. Antibody screening and major crossmatch test were performed using method 1 and method 2, and the difference of ΔHb (post-transfusion Hb minus pre-transfusion Hb) was compared after transfusion. The differences in ΔHb after transfusion were analyzed between the test group using method 1 and the control group without CD47 monoclonal antibody using ordinary microcolumn gel method. 【Results】 There was no significant difference in ΔHb between the test group using method 1 and test group using method 2 (8.40±0.71 vs 7.36±0.94, P>0.05). No significant difference was noticed in ΔHb between the test group using method 1 and the control group without CD47 monoclonal antibody (8.40±0.71 vs 6.59±0.77, P>0.05). 【Conclusion】 In the test group, major crossmatch test with method 1 has the same transfusion efficacy as the test with method 2. Method 1 is simple and easy to operate, and the results are objective and accurate. It is recommended to use method 1 for pre-transfusion antibody screening and major crossmatch tests for patients using CD47 monoclonal antibody.

【Objective】 To explore the feasibility of blood transfusion compatibility testing for multiple myeloma(MM) patients treated with anti-CD38 monoclonal antibody daratumumab (DARA) after DARA-Fab fragment blocking, and to evaluate the transfusion efficacy by comparing with dithiothreitol(DTT) method. 【Methods】 After DARA was prepared into DARA-Fab fragments using PierceFab preparation kit, the neutralization effects of different volumes (5, 10, 15, 30 μL) on screening cells and panel cells were confirmed. DARA-Fab fragments and screening cells with specific antigens and corresponding monoclonal antibody reagents were used as the experimental group and the control group with the same volume of saline for incubating and centrifugin.Twenty MM patients treated with DARA were selected for cross-matching with DARA-Fab and DTT respectively, and the laboratory indexes before and after transfusion were statistically analyzed, and the two blood matching methods were compared. 【Results】 After incubating and centrifuging, the results of DARA-Fab fragments(15, 30 μL) with screening cells and serum mixed with DARA were negative, while those of DARA-Fab(5, 10 μL) were positive. 15μL DARA-Fab treated antibody identification cells (2, 3, 4, 5, 7, 9, 11) were negative, antibody identification cells (1, 6, 8, 10, 12) were negative after 30 μL DARA-Fab fragments treatment; the results of MNS, Duffy, Kidd, Kell, Lewis, Rh blood group system of the experimental group were consistent with those of the control group; the hemoglobin (Hb) (g/L) of 20 patients after infusion of RBC (73.90±1.90) was significantly higher than that before transfusion (63.60±1.58), P<0.01. There was no significant difference in total bilirubin(TBil)(μmol/L)(16.25±3.54 vs 17.87±3.57), direct bilirubin(DBIL)(μmol/L)(6.31±2.32 vs 7.10±2.80)and indirect bilirubin(I-Bil)(9.94±1.38 vs 10.77±1.22) before and after infusion(P>0.05).And no statistical difference was noticed in Hb (10.75±1.04 vs 10.30±0.98), TBil (3.31±1.47 vs 3.31±0.55), DBIL(2.76±1.24 vs 2.60±0.83), and I-Bil(1.97±0.40 vs 2.82±0.53) between the DTT treatment method and the DARA Fab fragment treatment before and after transfusion(P>0.05). 【Conclusion】 DARA-Fab can remove the interference of RBC on cross matching by blocking CD38 antigen. This method has no effect on the antigens of common RBC blood group systems, and shows significant blood transfusion efficacy as that of DTT method.

OBJECTIVE To investigate the effect of polymorphisms of solute carrier organic anion transporter family, member 1B3(SLCO1B3) gene on the pharmacodynamics of mycophenolate mofetil(MMF) in patients with lupus nephritis. METHODS Patients with lupus nephritis who were treated in Jieyang People’s Hospital from September 2019 to April 2021 were selected. All subjects were treated with MMF for at least 12 months, or discontinued due to poor efficacy. The efficacy of MMF was evaluated. The SLCO1B3 334T>G/699G>A(rs4149117/rs7311358) genotype was detected using Agena MassARRAY®, and the correlation between gene polymorphisms and MMF pharmacodynamics was analyzed using SPSS 25.0 software. RESULTS The genotype frequencies of SLCO1B3 334T>G/699G>A were in Hardy-Weinberg equilibrium. The probability of poor MMF treatment effect of 334GG/699AA carriers was significantly higher than that of 334TT/699AA and 334TG/699GA carriers(P<0.001); Logistic regression showed that both 334GG/699AA and urine protein>2.5 g·(24 h)−1 were the risk factors for poor MMF treatment[OR=4.038(1.731, 9.420), P<0.001; OR=4.157(1.705, 10.137), P=0.002]. Combined analysis showed that patients with both 334GG/699AA genotype and urine protein>2.5 g·(24 h)−1 were at higher risk for poor efficacy[OR=8.563(3.301, 22.216), P<0.001]. CONCLUSION SLCO1B3 334T>G/699G>A is related to the efficacy of MMF treating lupus nephritis, and 334GG/699AA carriers are more likely to result in poor efficacy.

Objective:To systematically evaluate the effect of cognitive behavioral therapy (CBT) in elderly patients with depression.Methods:The randomized controlled trials on the effect of CBT in elderly patients with depression, published until December 15, 2022, were searched in PubMed, CINHAL, Cochrane Library, China Biology Medicine, China National Knowledge Infrastructure, WanFang Data, and VIP. Two researchers independently screened the literature, extracted data, and used the revised Cochrane risk of bias tool for randomized trials (ROB 2.0) to evaluate the quality of the included studies. Statistical analysis was conducted using Stata 16.0, and the quality of evidence was rated using Appraisal of Guidelines for Research and Evaluation (GRADE) predictor software.Results:A total of 11 randomized controlled trials were included, with a total of 833 elderly patients with depression. Randomized effect models were used to analyze outcome indicators such as depression, anxiety, and quality of life by combining effect quantities. Meta-analysis and GRADE evidence quality showed that compared to the control group, medium quality evidence showed that CBT could relieve depression in elderly depression patients with a statistical difference [ SMD=-1.58, 95% CI (-2.16, -0.99), P<0.05]. Low quality evidence suggested that CBT could alleviate anxiety in elderly depression patients also with a statistical difference [ SMD=-2.25, 95% CI (-4.04, -0.47), P<0.05]. Very low quality evidence indicated that CBT did not significantly improve the quality of life in elderly depression patients compared to conventional or pharmacological treatment [ SMD=-0.09, 95% CI (-2.07, 1.88), P>0.05] . Conclusions:Existing evidence suggests that CBT can alleviate depression and anxiety in elderly depression patients, but its improvement in quality of life is not yet significant. Treatment feedback and forms of CBT may become a research focus in recent years on intervention for elderly depression patients.

The aim of this study is to evaluate the in vitro and in vivo antibacterial potential of Ly-sZHSHW,a phage lysin against Acinetobacter baumannii infections,and to study its characteris-tics.The pET28a-Lys recombinant plasmid containing LysZHSHW coding gene was constructed by PCR,enzyme digestion and ligation using the expression plasmid pET28a as the backbone and ex-pressed in E.coli BL21(DE3).After confirming the expression of the LysZHSHW through West-ern blot analysis,its characterization and potential applications were assessed both in vitro and in vivo.The results showed that the pET28a-Lys recombinant plasmid was successfully constructed and the LysZHSHW protein was expressed correctly.The mass concentration of the purified en-zyme was 4 086 mg/L,which could be used for subsequent experiments.The enzymatic activity of LysZHSHW was determined to be 630 U/μg,with maximum activity observed at 25 ℃ and pH9.0.In vitro experiments demonstrated that 1 000 or 750 mg/L of LysZHSHW,in the presence of EDTA,resulted in a four-log reduction in bacterial counts without any cytotoxicity.In vivo,2.5 μg of LysZHSHW combined with EDTA could increase the survival rate of Galleria mellonel-la larvae infection model to 92.86％after 24 hours,and 0.15 mg of LysZHSHW reduced the bacte-rial load in the thighs of mice by 2.8 logs and alleviated the inflammatory response in muscle fi-bers.In conclusion,LysZHSHW derived from Acinetobacter baumannii bacteriophage exhibited characteristics such as stability at room temperature,alkaline pH,and safety,making it a promis-ing candidate as a novel antimicrobial agent.
