ObjectiveTo analyze the changes in the degree of coordination of China's major epidemic prevention and control efforts before and after the outbreak of the Corona Virus Disease 2019 (COVID-19), so as to explore the impact of epidemic prevention and control measures on coordination dynamics. MethodsA total of 3 864 policy documents related to epidemic prevention and control from January 2000 to December 2020 across 31 provinces (autonomous regions, and municipalities) in China were systematically collected. Contents specific to collaborative and cooperative efforts were extracted, and the extent of interdepartmental coordination were quantified to assess the effectiveness of epidemic prevention and control efforts. Wilcoxon signed-rank test was adopted to statistically analyze the differences between the indicators before and after the epidemic. ResultsThe average overall coordination level for major epidemic prevention and control in 31 provinces (autonomous regions, and municipalities) increased from 43.06% to 97.62%, and the average coordination levels in the eastern, central, and western China soared from 42.29%, 37.50%, and 47.46%, to 98.81%, 96.20%, and 97.46%, respectively, with statistically significant differences (all P<0.05). In terms of department categorization, coordination levels in the professional departments and the key support departments peaked at 100.00%, while other support departments rose to 95.43%, with an increase of 77.15%, 181.85%, and 139.89%, respectively, exhibiting noteworthy statistically significant differences (all P<0.001). ConclusionThe scope of coordination departments of China’s major epidemic prevention and control exists a remarkable surge following the COVID-19 outbreak, notable heightened coordination is particularly observed among the key support departments. Future endeavors should prioritize the roles played by diverse departments in epidemic prevention and control, enhancing both the clarity of departmental responsibilities and the effectiveness of interdepartmental coordination.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

Objective To compare the efficacy of renal proximal renal artery denervation(pRDN)and full-length renal artery denervation(fRDN)for treatment of hypertension.Methods Fifty-six hypertensive patients were enrolled and randomly assigned to full-length renal artery denervation group(n=25)and proximal renal artery denervation group(n=31).After the procedure,24-hour ambulatory blood pressure monitoring(24 h-ABPM)at 6 months and office blood pressure at 12 months was recorded for statistical analysis.Results The blood pressure at follow-up reduced significantly in both groups,while there was no significant difference between groups.The baseline office blood pressure in fRDN group and pRDN group was(180±15)/(104±10)mmHg and(180±12)/(103±8)mmHg,respectively,which decreased to(142±9)/(82±7)mmHg and(143±10)/(83±6)mmHg at 12 months postoperatively(P＜0.001 within groups and P＞0.05 between groups).The baseline 24 h-ABPM in the two groups was(162±13)/(95±8)mmHg and(160±12)/(94±8)mmHg,respectively,which decreased to(142±11)/(83±7)mmHg and(141±8)/(81±7)mmHg at 6 months postoperatively(P＜0.001 within groups and P＞0.05 between groups).However,there was no significant difference in the reduction of office blood pressure and ambulatory blood pressure between the two groups.No treatment-related adverse events were observed.Conclusions pRDN has similar antihypertensive effect to fRDN.

Objective:To evaluate the efficacy of acute T-cell lymphoblastic leukemia(T-ALL)in children and explore the prognostic risk factors.Methods:The clinical data of 127 newly diagnosed children with T-ALL admitted to five hospitals in Fujian province from April 2011 to December 2020 were retrospectively analyzed,and compared with children with newly diagnosed acute precursor B-cell lymphoblastic leukemia(B-ALL)in the same period.Kaplan-Meier analysis was used to evaluate the overall survival(OS)and event-free survival(EFS),and COX proportional hazard regression model was used to evaluate the prognostic factors.Among 116 children with T-ALL who received standard treatment,78 cases received the Chinese Childhood Leukemia Collaborative Group(CCLG)-ALL 2008 protocol(CCLG-ALL 2008 group),and 38 cases received the China Childhood Cancer Collaborative Group(CCCG)-ALL 2015 protocol(CCCG-ALL 2015 group).The efficacy and serious adverse event(SAE)incidence of the two groups were compared.Results:Proportion of male,age ≥ 10 years old,white blood cell count(WBC)≥ 50 × 109/L,central nervous system leukemia,minimal residual disease(MRD)≥ 1％during induction therapy,and MRD ≥ 0.01％at the end of induction in T-ALL children were significantly higher than those in B-ALL children(P＜0.05).The expected 10-year EFS and OS of T-ALL were 59.7％and 66.0％,respectively,which were significantly lower than those of B-ALL(P＜0.001).COX analysis showed that WBC ≥ 100 x 109/L at initial diagnosis and failure to achieve complete remission(CR)after induction were independent risk factors for poor prognosis.Compared with CCLG-ALL 2008 group,CCCG-ALL 2015 group had lower incidence of infection-related SAE(15.8％vs 34.6％,P=0.042),but higher EFS and OS(73.9％vs 57.2％,PEFS=0.090;86.5％vs 62.3％,PoS=0.023).Conclusions:The prognosis of children with T-ALL is worse than children with B-ALL.WBC ≥ 100 × 109/L at initial diagnosis and non-CR after induction(especially mediastinal mass has not disappeared)are the risk factors for poor prognosis.CCCG-ALL 2015 regimen may reduce infection-related SAE and improve efficacy.

Objective:To investigate the safety and efficacy of mitoxantrone liposome in the treatment of children with high-risk acute myeloid leukemia(AML).Methods:The children with high-risk AML who received the mitoxantrone liposome regimen at Wuhan Children's Hospital from January 2022 to February 2023 were collected as the observation group,and the children with high-risk AML who received idarubicin regimen were enrolled as controls,and their clinical data were analyzed.Time to bone marrow recovery,the complete remission rate of bone marrow cytology,the clearance rate of minimal residual disease,and treatment-related adverse reactions were compared between the two groups.Results:The patients treated with mitoxantrone liposome showed shorter time to recovery of leukocytes(17 vs 21 day),granulocytes(18 vs 24 day),platelets(17 vs 24 day),and hemoglobin(20 vs 26 day)compared with those treated with idarubicin,there were statistical differences(P＜0.05).The effective rate and MRD turning negative rate in the observation group were 90.9％and 72.7％,respectively,while those in the control group were 94.1％and 76.4％,with no statistical difference(P＞0.05).The overall response rate of the two groups of patients was similar.Conclusion:The efficacy of mitoxantrone liposome is not inferior to that of idarubicin in children with high-risk AML,but mitoxantrone liposome allows a significantly shorter duration of bone marrow suppression and the safety is better.

Objective:To investigate the accuracy of next-generation sequencing technology(NGS)in detecting the polymorphisms of HLA-DRB1,DQB1,DQA1,DRB3,DRB4,DRB5,DPA1 and DPB1 alleles in randomly-selected unrelated healthy individuals from Shenzhen Han population,investigate the potential reason for HLA-DRB1 allele dropout in routine NGS,and establish an internal quality control system.Methods:NGS-based HLA class Ⅱ genotyping was performed on 1 012 samples using the MiSeqDxTM platform.The suspected missed alleles indicated by the quality control software and HLA-DRB1 homozygotes were confirmed by PCR-SSOP or PCR-SBT methods.Results:A total of 139 alleles were detected,including HLA-DRB1(45),DRB3(7),DRB4(5),DRB5(7),DQA1(17),DQB1(21),DPA1(10)and DPB1(27).HLA-DRB 1*09:01(17.09％),15:01(10.72％);DRB3*02:02(25.99％),03:01(10.18％);DRB4*01:03(36.46％);DRB5*01:01(15.42％);DQA1*01:02(20.01％),03:02(17.19％);DQB1*03:01(19.47％),03:03(17.98％),05:02(11.66％),06:01(10.67％);DPA1*02:02(54.45％),01:03(31.18％)and DPB1*05:01(39.13％),02:01(16.90％)alleles were the most common alleles in Shenzhen Han population(frequencies＞10％).There was no statistical difference between the gene frequencies of HLA-DRB1 and DQB1 loci in our study.The HLA Common and Well-Documented Alleles in China(CWD2.4)(x2=12.68,P＞0.05).94 cases of HLA-DRB1 homozygous samples detected by NGS were retested by PCR-SSOP or SBT method,and one case of allele dropout at HLA-DRB1 locus was found.SBT method confirmed that the allele of DRB1*04:03 was missed.The laboratory internal quality control system was established.Two cases of new alleles were detected and named by WHO Nomenclature Committee for Factors of the HLA System.Conclusion:The HLA genotyping results based on NGS showed a significantly lower ambiguity rate.The HLA class Ⅱ alleles exhibit genetic polymorphism in the Han population of unrelated healthy individuals in Shenzhen.The independent method based on NGS in clinical histocompatibility testing has limitations and requires internal quality control strategies to avoid allele-dropout events.

Objective:To investigate the prognostic value of minimal residual disease(MRD)detected by multi-parameter flow cytometry(MFC)in pediatric patients with acute myeloid leukemia(AML)after induction chemotherapy.Methods:A retrospective study was conducted on 97 pediatric patients initially diagnosed with AML at Wuhan Children's Hospital from August 2015 to December 2022.The study analyzed the results of MRD detection using MFC after the first and second cycles of induction chemotherapy,and its association with prognosis were analyzed.Results:Following the first cycle of induction treatment,57 of the 97 patients tested positive for MRD(MRD1+,58.8％).Subsequently,19 patients remained MRD positive(MRD2+,19.6％)after the second cycle of induction treatment.Kaplan-Meier survival analysis showed that the estimated 3-year overall survival(OS)rate of the 37(64.9％)MRD1+patients who underwent transplantation was significantly higher than that of the 20(35.1％)MRD1+patients who did not undergo transplantation(84.6％vs 40.0％,P=0.0001).Among the 35 MRD1+MRD2-patients,the 3-year OS rate of the 25 children who underwent transplantation was higher than that of the 10 children who did not undergo transplantation(87.2％vs 70.0％,P=0.3229).The 3-year OS rate of the 19 MRD1+MRD2+patients was lower than that of the 35 MRD1+MRD2-patients(57.4％vs 81.8％,P=0.059).In the 19 MRD2+patients,the 3-year OS rate of the 12 children who underwent transplantation was significantly higher than that of the 7 children who did not undergo transplantation(80.8％vs 14.3％,P=0.0007).There was no significant difference in 3-year OS between the 12 MRD1+MRD2+patients and 25 MRD1+MRD2-patients,both treated with transplantation(80.8％vs 87.2％,P=0.8868).In those not treated with transplantation,the 7 MRD1+MRD2+patients had a significantly lower 3-year OS compared with the 10 MRD1+MRD2-patients(14.3％vs 70.7％,P=0.0114).Further multivariate analysis indicated that MRD2 positivity and transplantation were both independent prognostic factors(P=0.031,0.000),while MRD1 positivity was not significantly associated with the overall prognosis of 97 patients(P=0.902).Conclusion:MRD positivity following the second cycle of induction chemotherapy is an independent risk factor for unfavorable outcomes in children with AML.MRD2 positivity indicates a poorer prognosis and can help to identify the candidates requiring transplantation.MRD2 positivity is not a contraindication for transplantation in pediatric patients,and early transplantation significantly improves the prognosis of high-risk patients.

Objective:To summarize the clinical features of reversible posterior encephalopathy syndrome(PRES)after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in children.Methods:The clinical data of six children who developed PRES after undergoing allo-HSCT in the Department of Hematology of Wuhan Children's Hospital from June 2016 to December 2022 were retrospectively analyzed,and their clinical characteristics,imaging examination,laboratory examination,and treatment regression were summarized.Results:Among 281 children underwent allo-HSCT,6 cases(2.14％)developed PRES,with a median age of 5.1(1.5-9.7)years old.4 cases underwent related haploidentical donor transplantation,and 2 cases underwent sibling allografting and unrelated donor allografting donor transplantation,respectively.All six children had an acute onset of illness,with clinical manifestations of nausea and vomiting,seizures,psychiatric disorders,visual disturbances.The five cases elevated blood pressure.All children with PRES were treated with oral immunosuppressive drugs during seizures,and 3 cases were combined with different degrees of graft-versus-host disease.Most of the children showed effective improvement in clinical symptoms and imaging after adjusting/discontinuing suspected medications(cyclosporine,etc.)and symptomatic supportive treatments(oral antihypertensive,diazepam for antispasmodic,mannitol to lower cranial blood pressure),and one of them relapsed more than 8 months after the first seizure.Conclusion:PRES is rare after hematopoietic stem cell transplantation in children,and its onset may be related to hypertension,cytotoxic drugs,graft-versus-host disease,etc.Most of them can be recovered after active treatment,but not completely reversible,and the prognosis of those who combined with TMA is poor.

Objective:To evaluate the difference in efficacy between liposuction combined with single-port endoscopic subcutaneous adenomectomy and traditional open surgery in treating adolescent male breast development disorder,and to compare their effects on patients'anxiety levels and quality of life.Methods:A total of sixty-four patients with adolescent male mammary gland dysplasia who underwent surgery at our hospital between March 2022 and June 2023 were included in this retrospective analysis,with 28 cases in the open surgery group and 36 cases in the single-hole endoscopic group.The study compared various parameters including surgery duration,intraoperative bleeding,incision length,hospitalization duration,treatment cost,and postoperative complications,alongside collecting GAD-7,SF-36,and SCAR questionnaire scores from the pa-tients.Results:The single-port endoscopy group,in comparison to the open surgery group,showed a slightly longer operation time and higher treatment cost but had a shorter hospitalization duration and smaller incision.There was no significant difference observed between the two groups concerning intraoperative bleeding.Notably,the single-port endoscopy group exhibited more significant improvements in SCAR,SF-36,and GAD-7 scores(P＜0.05).Conclusion:Com-pared with traditional open surgery,liposuction combined with single-port endoscopic subcutane-ous adenomectomy is more effective in treating adolescent gynecomastia.This approach not only offers better aesthetic outcomes but also proves effective in reducing patient anxiety and signifi-cantly enhancing their quality of life.

Objective:To compare thulium laser enucleation of the prostate(ThuLEP)with plasma kinetic resection of the prostate(PKRP)in the treatment of BPH.Methods:We retrospectively analyzed the medical records of 160 cases of BPH treated by ThuLEP(the observation group,n=80)or PKRP(the control group,n=80)in our hospital from January 2021 to December 2023.We recorded the operation time,bladder irrigation time,catheter retention time,hospitalization time,postoperative complica-tions,and pre-and postoperative maximum urinary flow rate(Qmax),residual urine volume(PVR),prostate-specific antigen(PSA)and prostate volume,followed by comparison of the data obtained between the two groups of patients.Results:Compared with the controls,the patients of the observation group showed significantly shorter operation time([67.25±7.24]vs[60.10±5.15]min,P<0.05),bladder irrigation time([46.90±10.77]vs[43.24±6.65]h,P<0.05),catheterization time([5.60±1.31]vs[5.03±1.24]d,P<0.05)and hospitalization time([7.31±2.00]vs[6.55±1.67]d,P<0.05),higher Qmax([18.50±1.24]vs[20.68±1.45]ml/s,P<0.05),lower PVR([12.10±3.53]vs[10.82±3.10]ml,P<0.05),PSA([4.60±0.78]vs[3.38±0.40]μg/L,P<0.05)and prostate volume([25.35±6.46]vs[20.12±5.13]ml,P<0.05)at 3 months after surgery,but no statistically significant difference in the total incidence of postoperative complications(7.50%[6/80]vs 5.00%[4/80],P>0.05).Conclusion:ThuLEP,with its advantages of notable effect,short operation and hospitaliza-tion time,significant improvement of urinary flow dynamics and prostate function,deserves clinical promotion for the treatment of BPH.
