In 2022， Hainan provincial government launched the project for the prevention and control of viral hepatitis with the goals of a hepatitis B screening rate of 90%， a diagnostic rate of 90%， and a treatment rate of 80% among people aged 18 years and above by the year 2025， and the main intervention measures include population-based prevention， case screening， antiviral therapy， and health management. As of December 31， 2024， a total of 6.875 million individuals in the general population had been screened for hepatitis B， with a screening rate of 95.6%. A total of 184 710 individuals with positive HBsAg were identified， among whom 156 772 were diagnosed through serological reexamination， resulting in a diagnostic rate of 84.9%. A total of 50 742 patients with chronic hepatitis B were identified， among whom 42 921 had hepatitis B-specific health records established for health management， with a file establishment rate of 84.6%. A total of 31 553 individuals received antiviral therapy， with a treatment rate of 62.2%. A total of 2.503 million individuals at a high risk of hepatitis C were screened， among whom 4 870 tested positive for HCV antibody and 3 858 underwent HCV RNA testing， resulting in a diagnostic rate of 79.2%， and 1 824 individuals with positive HCV RNA were identified， among whom 1 194 received antiviral therapy， with a treatment rate of 65.5%. In addition， 159 301 individuals with negative HBsAg and anti-HBs and an age of 20 — 40 years were inoculated with hepatitis B vaccine free of charge. Through the implementation of the project for the prevention and control of viral hepatitis， a large number of hepatitis patients have been identified， treated， and managed in the province within a short period of time， which significantly accelerates the efforts to eliminate the crisis of viral hepatitis.

Objective: To analyze the disease burden of acute gastrointestinal illness (AGI) caused by non-typhoidal Salmonella and Vibrio Parahaemolyticus in Zhejiang Province, so as to provide the reference for the prevention and control of foodborne diseases. Methods: The detection rates of non-typhoidal Salmonella and Vibrio parahaemolyticus in 2022 were collected through the Zhejiang Foodborne Disease Outbreak Surveillance System. The number of cases, incidence and hospitalizations of AGI caused by non-typhoidal Salmonella and Vibrio parahaemolyticus were calculated. Disability-adjusted life years (DALY) were used to analyze the disease burden of AGI caused by non-typhoidal Salmonella and Vibrio parahaemolyticus among different age groups. Results: The number of AGI cases caused by non-typhoidal Salmonella in Zhejiang Province in 2022 was 889 500 person-times, the incidence rate was 1 352.42/105, the number of hospital visits was 328 900 person-times, the DALY was 972.69 (95%CI: 771.68-1 164.16) person-years, and the DALY rate was 1.48 (95%CI: 1.17-1.77) /105. The incidence rate and DALY rate were highest in the children aged under 5 years, reaching 3 989.51/105 and 13.93 (95%CI: 8.67-18.42) /105, respectively. The number of AGI cases caused by Vibrio parahaemolyticus in Zhejiang Province was 639 400 person-times, the incidence rate of 972.16/105,the number of hospital visits was 166 800 person-times, the DALY was 509.30 (95%CI: 411.75-699.62) person-years, and the DALY rate was 0.78 (95%CI: 0.63-1.06)/105. The incidence rate and DALY rate were highest in the residents aged 45 to <65 years, reaching 1 383.55/105 and 1.27 (95%CI: 1.14-1.96)/105, respectively. Conclusions The incidence and DALY of AGI caused by non-typhoidal Salmonella were relatively high in Zhejiang Province. The AGI caused by non-typhoidal Salmonella in the children under 5 years and the AGI caused by Vibrio parahaemolyticus in the residents aged 45 to <65 years need to be monitored with priority.

Objective To investigate the safety and efficacy of novel bioabsorbable vascular scaffold(BVS)in the treatment of patients with complex coronary artery disease.Methods This was a retrospective,matched,single-center observational study.45 patients with coronary atherosclerotic cardiopathy received BVS treatment in the cardiovascular medicine department Department of the Affiliated Hospital of Guangdong Medical University from June 2020 to June 2021(BVS),and 45 patients treated with drug-eluting stents(DES)group were selected according to matching study requirements during the same period.Baseline,surgical,and follow-up data were compared between the two groups to evaluate safety and efficacy.The main measures of safety were:surgical time,intraoperative adverse events,etc.,and the end point of efficacy was target lesion failure(TLF),including cardiac death,target vessel myocardial infarction,and ischa-driven target lesion revascularization.Results A total of 90 patients were enrolled in this study,all of whom were followed up for at least 3 years.There were 20 cases of bifurcation lesions and 25 cases of diffuse long lesions in the two groups,and 50 cases of imaging were reviewed among the 90 patients.The proportion of stable coronary heart disease,history of diabetes,history of hypertension,history of smoking,pre-dilated balloon pressure and postoperative diastolic blood pressure in BVS group was higher than that in DES group,and the proportion of family history was lower than that in DES group(all P＜0.05).There were no statistically significant differences in the rates of cardiac death,target vessel myocardial infarction,and ischemia-driven revascularization of target lesions between the two groups(all P＞0.05).Binary Logistic regression model analysis showed that the diameter stenosis ratio of target lesions was an independent risk factor for intrastent restenosis(OR 2.786,95％CI 1.096-7.081,P=0.031).Conclusions Compared with traditional DES,BVS implantation has consistent safety and efficacy in the treatment of complex coronary artery disease within 3 years.The diameter stenosis ratio of target lesions was an independent risk factor for intrastent restenosis.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

OBJECTIVE: To explore clinical features, treatment methods and clinical effects of cervical spondylosis with proximal muscular atrophy. METHODS: Eleven patients with proximal-type cervical spondylotic amyotrophy were retrospectively studied from September 2016 to November 2020, including 7 males and 4 females, aged 38 to 68 years old. Clinical symptoms, MRI and neuroelectrophysiological manifestations were analyzed, and patients were treated with conservative treatment or anterior cervical decompression fusion surgery, respectively. The efficacy was evaluated by manual muscle test (MMT) before and after treatment, and patients' satisfaction was followed up at the same time. RESULTS: All patients were followed up for 6 to 19 months. All 11 patients were unilateral, mainly manifested by atrophy of deltoid muscle, supraspinatus muscle and infraspinatus muscle, and may be accompanied by ipsilateral neck and shoulder pain at early stage. MRI showed lesions at C_4,5, C_5,6 segments were more common. Electrophysiological examination showed the affected muscle was denervated, and amplitude of compound muscle action potential (CMAP) of innervated nerve on the affected side was lower than that on the healthy side. All patients were obtained bone fusion. One patient who were underwent anterior cervical corpectomy and fusion (ACCF) occurred developed contralateral C5 nerve root paralysis after operation, which recovered completely after 10 weeks of symptomatic treatment. At 12 months after operation, the efficacy was evaluated according to MMT, 3 patients were treated conservatively, 2 patients excellent and 1 good;in 8 patients treated by operation, 3 patients were excellent, 4 good, and 1 moderate. CONCLUSION The incidence of cervical spondylosis with proximal muscular atrophy is low, which is manifested as unilateral proximal muscle atrophy and may be accompanied by ipsilateral neck and shoulder pain in the early stage. Combined with MRI and neuroelectrophysiological examination, misdiagnosis could be reduced. In the early stage of disease, especially in the case of nucleus pulposus protrusion leading to nerve compression, conservative treatment could be taken. When the conservative treatment is ineffective or the pain cannot be tolerated, anterior decompression surgery is recommended, and the overall effect is satisfactory.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Objective: To investigate the clinicopathological, immunophenotypic and molecular features of colorectal amphicrine carcinoma (AC). Methods: Eight cases of colorectal AC were collected at the Nanjing Drum Tower Hospital and Nanjing First Hospital, Nanjing, China from 2013 to 2020. The histopathological, immunohistochemical and molecular features were analyzed. The relevant literature was reviewed. Results: There were 6 males and 2 females, with an average age of 56 years (range 28-80 years). The tumor sites were as follows: 4 cases in sigmoid colon, 3 cases in rectum, and 1 case in transverse colon. Microscopically, there were three different patterns in the tumors, including nests with collagen hyperplasia, sheets of cells with scant stroma, and glandular or cribriform growth of goblet- or signet ring-like cells. The tumor cells generally had abundant cytoplasm with abundant mucin or eosinophilic granules. The nuclei were oval or irregular with fine chromatin and inconspicuous nucleoli. Mitotic figures were common. Neuroendocrine granules and mucin granules could be identified clearly under electron microscope. All cases showed frequent perineural and lymphovascular invasions, lymphatic metastasis, and advanced stage. Regarding immunohistochemical and specific stains, the tumor cells expressed more than two neuroendocrine markers, particularly CD56 and synaptophysin which were diffusely positive in 7 of the 8 cases. They also showed intracellular mucin in the amphicrine components which was positive for D-PAS. KRAS G12C or NRAS Q61 gene mutations were found in 2 patients. Among the six cases with complete follow-up, four of them died of the disease within three years of the diagnoses, while two were alive without known disease progression. Conclusions: Colorectal AC is a rare, distinct entity with both epithelial and neuroendocrine differentiation. It mainly occurs in the sigmoid colon and rectum. It typically has aggressive clinical courses, dismal prognosis and characteristic histological features and immunophenotype, which highlight the importance of recognizing this entity for clinicians and pathologists.

Objective:To analyze the role of patient support system in multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) treatment adherence and outcome, and provide evidence for deepening the patient-centered support system.Methods:Based on the stakeholder analysis, definite stakeholders (administrators from the Department of Medical Insurance, and those from the provincial CDC), expectant stakeholders (administrators from regional CDC, health workers from primary CDCs, medical workers from designated MDR/RR-TB hospitals and MDR/RR-TB patients), and latent stakeholders (MDR/RR-TB patient families and their neighbors or colleagues) were selected using a purposive sampling. These stakeholders were subject to a semi-structured interview on patient support. The inclusion of participants ceased after reaching code or thematic saturation and meaning saturation, while thematic framework analysis was applied in interview data.Results:The 25 interviewees included could be categorized into three groups of stakeholders, i. e., 4 definite stakeholders, 19 expectant stakeholders and 2 latent stakeholders. Three themes summarized in this regard were definite stakeholders providing policy support to advance these patients′ access to standardized diagnosis and treatment services; diagnosis and treatment and management support of expectant stakeholders of these patients to encourage their compliance to treatment and enable their access to high quality medical care; and support from latent stakeholders as a critical guarantee for the patients to welcome a desirable treatment outcome. Psychological support provided under MDR/RR-TB basic care program in some provinces contributed positively to raising patients′ compliance. Economic support, treatment support from family menmbers ccould help the patients to welcome desirable outcomes.Conclusions:MDR/RR-TB patient-centered support system operating in the Yangtze River delta provide the patients with MDR/RR-TB diagnostic and treatment services of some accessibility. Given the progress, there are still shortcomings for the respective stakeholders to enhance their attention and collaboration to improve the access and equity to medical service.
