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.

O'Donnell-Luria-Rodan(ODLURO)syndrome is an autosomal dominant genetic disorder caused by mutations in the KMT2E(lysine methyltransferase 2E)gene.The Third Xiangya Hospital of Central South University admitted a 12-year and 9-month-old male patient who presented with growth retardation,intellectual disability,and distinctive facial features.Peripheral blood was collected from the patient,and DNA was extracted for genetic testing.Chromosome karyotyping showed 46XY.Whole-exome sequencing and low-coverage massively parallel copy number variation sequencing(CNV-seq)revealed a 506 kb heterozygous deletion in the 7q22.3 region,which includes 6 genes,including KMT2E.The patient was diagnosed with ODLURO syndrome.Both the patient's parents and younger brother had normal clinical phenotypes and genetic test results,indicating that this deletion was a de novo mutation.The clinical and genetic characteristics of this case can help increase clinicians'awareness of ODLURO syndrome.

Tumor-induced osteomalacia(TIO)is a rare paraneoplastic syndrome in which tumor-induced osteochondrosis is a metabolic bone disease caused by increased renal excretion of phosphorus due to excessive secretion of fibroblast growth factor 23(FGF23)by tumor tissue.We report here a rare case of TIO in which the tumor was found in the hyoid body and the patient had tertiary hyperparathyroidism.The patient's symptoms did not improve after removal of the tumor from the hyoid body,and the patient's hypophosphatemia was gradually improved after subsequent removal of the left parathyroid gland.TIO derived from the tongue tumor is very rare,and also subsequent tertiary hyperparathyroidism is even rarer.This report helps to improve the understanding of TIO and provides reference in the diagnosis and treatment of TIO.

Building a strong public health system has become an urgent task in the new era. Based on more than eight years of systematic research， we believe that five aspects need to be prioritized for a strong system. First， we should change the perspective on public health， using the word “gonggong jiankang” to replace “gonggong weisheng” and the word “gonggong jiankang tixi” to replace “gonggong weisheng tixi”， to lead the public health system development. Second， we should develop a suitable public health system and continuously improve the health capacity for governance. Third， we should make it clear that the goal of building a strong system is not far-fetched， and we need to consolidate the existing institutional advantages of China’s public health system： when encountering major problems， we can maintain a unified goal and mobilize the whole society to cooperate effectively to accomplish the goal. However， we need to make up for shortcomings one by one， especially to solve the key problem of lacking a strong coordination mechanism in daily work. Fourth， we should pursue excellence and consolidate the“suitable” mechanism proven in the process of coping with the COVID-19， so that efficient mechanisms to deal with major issues can be used in routine work， and efforts should be made to consolidate the advantages of prevention and control of infectious diseases and emergency response，so as to achieve the balanced development of regions categories and units.Finally， it is necessary to strengthen the coordination of government and research institutions， in the aspects of technological innovation， talent team building and accurate consulting services， and work together to pursue a suitable and strong system to realize the modernization of the health system and capacity for governance.

Objective:To advance the understanding of X-linked adrenal hypoplasia congenita(XL-AHC)through genetic analysis.Methods:Genomic DNA was extracted from peripheral blood of three patients with XL-AHC and their family members as well. Pathogenic genes were screened with whole exome sequencing followed by Sanger sequencing and pedigree verification.Results:All three probands were diagnosed as primary adrenal insufficiency at early age and developed hypogonadotropic hypogonadism in adolescence. The proband 1 was hemizygous for c. 420delG(p.R141Gfs*123)mutation in exon 1 of NR0B1 gene. His mother was a heterozygous mutation carrier while his brother did not carry the mutation, which was consistent with the X-linked recessive inheritance. A hemizygous mutation c. 212_213delAA(p.K71Rfs*41)of NR0B1 gene was detected in both proband 2 and proband 3. These two novel mutations were not reported in HGMD database.Conclusions:In this study, two novel NR0B1 mutations, c. 420delG and c. 212_213delAA were identified in 3 patients with XL-AHC. For men with early onset of adrenocortical hypofunction, XL-AHC should be considered. Early genetic screening of NR0B1 gene is helpful for early diagnosis.

Objective:To explore the underlying genetic cause in two patients with mucopolysaccharidosis(MPS)using the whole-exome sequencing.Methods:Genomic DNA was extracted from the peripheral blood of two patients with MPS and their family members. Sanger sequencing and pedigree verification were performed on the pathogenic variants filtered by whole-exome sequencing. The function of the mutation sites was analyzed by bioinformatics software. The effect of the splice mutation on mRNA was further determined by reverse transcription-PCR(RT-PCR).Results:The proband 1 was a 25-year-old male, who carried compound heterozygous mutations of α-L-iduronidas(IDUA) gene: p. T179R and p. S633L, and was diagnosed as MPSⅠ. His mother and sister carried heterozygous p. T179R, while his father carried heterozygous p. S633L, consistent with the autosomal recessive inheritance pattern. The proband 2 was a 3-year-old male, who was hemizygous for IVS 6-8A>G of iduronate-2-sulfatase(IDS) gene. His mother and grandmother were heterozygous for this mutation, consistent with the X-linked recessive inheritance. The proband 2 was diagnosed as MPSⅡ. Sequencing of RT-PCR products showed that the IVS 6-8A>G mutation activated an upstream cryptic splice-site in intron 6, leading to 7 nucleotide insertion in exon 7, frameshift, and shorter peptide chain.Conclusion:In this study, IDUA p. T179R and p. S633L, and IDS IVS 6-8A>G mutations were found in two patients with MPS by whole exome sequencing, which further expanded the genotypic and phenotype spectrum of MPS.

Objective:Kallmann syndrome(KS) is a complex genetic disease characterized by congenital hypogonadotropic hypogonadism and anosmia. More than 20 genes have been reported to be associated with KS. Herein, we explore potential genetic aberration in 3 KS patients using the whole-exome sequencing. The potentially pathogenic variants filtered were validated by Sanger sequencing.Methods:Genomic DNA was extracted from the peripheral blood of 3 patients with KS and their family members. Sanger sequencing and pedigree verification were performed on the pathogenic variants identified using whole-exome sequencing. The function of the mutation sites were analyzed with bioinformatics software.Results:The proband 1 was a 25 years old male, characterized by lower gonadotropin gonad hypofunction, early grey hair and bilateral sensorineural hearing loss. A heterozygous mutation c. 475C>T(p.R159W) of SOX10 gene was detected in the proband 1. His mother, sister and cousin who had KS phenotype were also found carrying this mutation, showing an autosomal dominant inheritance. The proband 2 was a 15-year-old male with hypogonadotropic hypogonadism and unilateral renal agenesis. The proband was hemizygous for c. 844delC(p.R282Vfs*28) of ANOS1 gene, his mother was heterozygous for the mutation, which was consistent with the X-linked recessive inheritance. The proband 3 was a 21 years old female, characterized by hypogonadotropic hypogonadism and anosmia. A heterozygous missense mutation c. 149G>A(p.R50Q) was detected in FGF17 gene. The mutation p. R50Q was predicted to be pathogenic by the SIFT and PolyPhen2 programs, and has not been reported in HGDM database yet, which considered to be a novel mutation.Conclusion:KS is a clinically and genetically heterogeneous disease. In this study, ANOS1 c. 844delC, SOX10 c. 475C>T and FGF17 c. 149G>A mutations were found in 3 patients with KS by whole exome sequencing, which would expand the genotypic and phenotype spectrum of KS.

Objective:To investigate the serum hepcidin level and risk factors associated with peripheral arterial disease (PAD) and foot ulcer in type 2 diabetic patients.Methods:From January 2019 to June 2019, 70 patients with type 2 diabetes in Department of Endocrinology of Xiangya Third Hospital were selected, including 21 newly diagnosed patients with type 2 diabetes (DM group), 23 patients with lower extremity vascular disease (PAD group) and 26 patients with foot ulcer (DF group). Serum hepcidin was determined by enzyme linked immunosorbent assay (ELISA). The serum levels of hepcidin in different groups were compared, and the correlation between diabetic lower extremity vascular disease and foot ulcer was analyzed.Results:⑴ The hemoglobin, albumin, triglycerides and total cholesterol were significantly lower in DF group compared with PAD and DM groups ( P<0.05), while the DF group patients were with higher white blood cell (WBC) count and high sensitivity C reactive protein (hs-CRP) than patients in PAD and DM groups ( P<0.05). DF group also showed significantly higher WBC, hs-CRP and neutrophil ratio level (NEUT%) than DM group ( P<0.05). The inflammatory indicators of WBC, hs-CRP and NEUT% showed no significant difference between DM group and PAD group ( P>0.05). ⑵ The levels of hepcidin in DF and PAD groups were higher than those in DM group, while that in DF group were higher than those in PAD group ( P<0.05); Hepcidin was positively correlated with systolic blood pressure, WBC count, NEUT% and ferritin ( P<0.05), and negatively correlated with hemoglobin, glycosylated hemoglobin, albumin and 25-hydroxyvitamin D ( P<0.05). ⑶ Binary multivariate logistic regression analysis showed that elevated hepcidin level was an independent risk factor for diabetic foot ulcer [ OR=1.755, 95% CI: 1.063-2.897, P=0.028]. Conclusions:The fluctuation of serum hepcidin level in diabetic patients is related to the stimulation of inflammation, the degree of anemia and the nutritional status, which means it might be an early indicator of inflammation in diabetic patients with peripheral arterial disease. Moreover, the increase of hepcidin is an independent risk factor for diabetic foot ulcers in our study.

Type 1 diabetes mellitus and autoimmune thyroid disorders are the most common combination of autoimmune polyendocrine syndrome type Ⅲ(APS Ⅲ). However, APS Ⅲ combined with myasthenia gravis is rare. We described a male patient with myasthenia gravis, type 1 diabetes mellitus, and Hashimoto thyroiditis, who was diagnosed as APS Ⅲ. The human leukocyte antigen (HLA)type was analyzed in this patient. We subsequently reviewed 11 cases of APS Ⅲ combined with myasthenia gravis. This review revealed that HLA-DR9/DQ9 might be a specific HLA subtype associated with APS Ⅲ and complicated with myasthenia gravis .

Objective: To explore the clinical phenotypes and the genetic causes for a 5 years old boy with unexplained growth retardation, developmental delay, special face, and hypothyroidism. Methods: Routine G-banding was performed to analyze the karyotype of the patient and his parents. In addition, whole exome sequencing and low-coverage massively parallel CNV sequencing (CNV-seq) were used to determine the potentially pathogenic variants as well as the copy number variations (CNVs). Results: The child′s karyotype was 46, XY, and his parents′ karyotypes were normal.However, CNV-seq identified a heterozygous deletion of 1.56 Mb on chromosome region 7q11.23 in the patient, including 24 protein-coding genes, which were associated with Williams-Beuren syndrome. His parents′ results of CNV-seq were normal, indicating a de novo CNVs. Conclusion A Williams-Beuren syndrome child presenting with hypothyroidism was diagnosed by CNV-seq, which would contribute to further understanding the clinical phenotypes and pathogenesis of this disease.
