Objective:To analyze the external quality control assessment results of fluoride testing laboratories in endemic disease prevention and control institutions nationwide from 2006 to 2023, investigate the quality control capabilities of these laboratories in various provinces, prefectures, cities, and counties nationwide, and ensure the accuracy and reliability of surveillance data on endemic fluorosis nationwide.Methods:Using retrospective analysis, the external quality control assessment results of all participating fluoride testing laboratories of national endemic disease prevention and control institutions from 2006 to 2023 were summarized and analyzed. The assessment results from 2006 to 2008 were tested for outliers using Grubbs method, homogeneity of variance using Cochran method, excluding the assessment data of unqualified laboratories, calculating the total mean and total standard deviation, Z-score method was used to test the assessment of laboratories, and statistical analysis and judgment were done when the result of │Z│ < 3. The assessment results from 2009 - 2023 were obtained from all laboratories. In 2010, two tests were conducted in the first and second half of the year, and the Z-ratio scores of each laboratory were calculated using robust statistics. When │Z│≤2, the assessment was qualified; when 2 < │Z│ < 3, the assessment was basically qualified; when│Z│≥3, the assessment was unqualified, and the consensus value came from all participating laboratories in the assessment.Results:From the beginning of quality control operation in 2006 to 2023, the number of laboratories participated in external quality control assessments had significantly increased. The number of laboratories participated in water fluoride assessment increased from 30 in 2006 to 1 277 in 2023, and the number of laboratories participated in urine fluoride assessment increased from 29 to 497. The number of laboratories participated in the brick tea fluorine assessment had increased from 43 in 2014 to 193 in 2023. The assessment results showed that when │Z│ < 3, the total qualified rate of fluoride external quality control in fluoride testing laboratories of national endemic disease control institutions was 95.2%, with the lowest being 87.1% (27/31) in 2008 and the highest being 100.0% (394/394) in 2014. When │Z│≤2, the total feedback pass rate was 88.4%, with the lowest being 79.3% (288/363) in the first half of 2010 and the highest being 99.5% (392/394) in 2014. The assessment results showed that when │Z│ < 3, the total pass rate of urine fluoride external quality control in fluoride testing laboratories of national endemic disease control institutions was 98.0%, with the lowest being 86.2% (25/29) in 2006 and 2007, respectively, and the highest being 100.0% (68/68) in 2014. When │Z│≤2, the total qualification rate was 93.7%, with the lowest being 86.5% (64/74) in the second half of 2010 and the highest being 100.0% (68/68) in 2014. The assessment results showed that when│Z│ < 3, the total pass rate of extra-fluoride quality control of brick tea in fluoride testing laboratories of national endemic disease control institutions was 95.4%, with the lowest being 85.0% (164/193) in 2023, and the highest being 100.0% (43/43, 51/51, 79/79) in 2014, 2015 and 2016, respectively. When │Z│≤2, the total pass rate was 89.2%, with the lowest being 72.7% (32/44) in 2017 and the highest being 100.0% (43/43) in 2014. From 2009 to 2023, there were a total of 21 provincial-level laboratories that passed the water fluoride detection assessment, including 3 provinces where all prefecture level and county-level laboratories were qualified. The assessment results of urinary fluorine showed that there were 11 qualified provincial-level laboratories and 1 prefecture-level laboratory. From 2014 to 2023, the assessment results of brick-tea fluorine showed that there were 5 provincial-level laboratories that passed the tea fluorine testing assessment and no prefecture-level laboratory.Conclusions:Conclusion: From 2006 to 2023, the number of fluoride testing laboratories participating in external quality control assessment has increased year by year, and most provincial, municipal and county-level laboratories have good fluoride testing capabilities, which can meet the testing needs of endemic disease prevention and monitoring. For some laboratories with problems, targeted rectification should be carried out to improve the quality of detection, in order to provide better technical support for the monitoring of endemic fluorosis areas.

Updates to the modern diagnosis of GERD: Lyon consensus 2.0 was published online in September 2023. It presents 23 consensus statements that update the modern definition of gastro-esophageal reflux disease (GERD) and optimize the diagnosis and management of GERD, providing an up-to-date basis for the diagnosis and treatment of GERD. The international consensus is based on the evaluation of studies conducted since the original consensus was published. However, due to the limitations of evidence-based evidence and the differences in national conditions, populations, and economic levels of different countries, it is necessary to interpret its applicability in China, so as to better promote the dissemination of its content and its implementation, and provide patients with the most appropriate guidance for clinical practice.

Objective:To investigate the impacts of hierarchical management based on medical alliance on the patency of arteriovenous graft (AVG),and provide a basis for further exploration of optimal AVG management.Methods:In this retrospective cohort study, clinical and follow-up data of patients with AVG established in the First Affiliated Hospital of Zhengzhou University from January 1, 2018 to December 31, 2021 were analyzed. Patients were divided into medical alliance group and non-medical alliance group according to whether they were under hierarchical management model, and the patency rate of AVGs and the incidence of clinical events were compared between the two groups.Results:A total of 328 AVGs were included in this study, which were from 151 hemodialysis centers, including 189 AVGs (57.6%) from 72 centers in medical alliance group, and 139 AVGs (42.4%) from 79 centers in non-medical alliance group. The age of the patients was (55.57±11.80) years, among whom 130 (39.6%) were males and 126 (38.4%) were diabetic. The follow-up time of AVGs in this cohort was 15.5 (9.5, 26.2) months, with 15.4 (9.8, 25.2) months in medical alliance group and 15.5 (9.2, 27.3) months in non-medical alliance group. The incidence of thrombosis or occlusion (0.328 times/patient-year), graft dissection (0.007 times/patient-year), graft infection (0.030 times/patient-year), and catheter utilization (0.043 times/patient-year) in the medical alliance group were lower than those in the non-medical alliance group (0.589 times/patient-year, 0.040 times/patient-year, 0.054 times/patient-year and 0.147 times/patient-year, respectively), and there was no significant difference in clinic follow-up rates between the two group (1.91 times/patient-year vs. 1.94 times/patient-year). The median primary patency time was 17.4 (95% CI 11.3-23.5) months, the median primary assisted patency time was 32.6 (95% CI 25.0-40.2) months, and the median secondary patency time was 47.9 (95% CI 40.0-55.8) months in the medical alliance group, compared with 12.3 (95% CI 9.4-15.2) months, 19.4 (95% CI 14.3-24.5) months, and 34.6 (95% CI 29.3-39.9) months in the non-medical alliance group, respectively. Primary patency were significantly higher in the medical alliance group (77.4%, 62.2%, 39.9%, and 26.6%) than those in the non-medical alliance group (71.1%, 50.1%, 30.6%, and 13.4%) at 6, 12, 24, and 36 months (Log-rank test, χ2=4.504, P=0.034). Primary assisted patency were significantly higher in the medical alliance group (90.9%, 84.3%, 67.1%, and 46.1%) than those in the non-medical alliance group (89.2%, 75.7%, 42.0%, and 16.6%) at 6, 12, 24, and 36 months (Log-rank test, χ2=10.655, P=0.001). Secondary patency were significantly higher in the medical alliance group (96.8%, 91.8%, 84.2%, and 74.0%) than those in the non-medical alliance group (89.9%, 85.8%, 69.3%, and 47.5%) at 6, 12, 24, and 36 months (Log-rank test, χ2=11.634, P=0.001). Multivariate Cox regression analysis showed that it was a protective factor for primary patency ( HR=0.708, 95% CI 0.512-0.980, P=0.037), primary assisted patency ( HR=0.506, 95% CI 0.342-0.749, P=0.001) and secondary patency ( HR=0.432, 95% CI 0.261-0.716, P=0.001) under the medical alliance model. Conclusion:The hierarchical management based on medical alliances can improve the patency of AVGs and reduce the incidence of clinical events.

Objective:To investigate the efficacy and related influencing factors of autologous hematopoietic stem cell transplantation(auto-HSCT)as first-line consolidation therapy for newly diagnosed elderly patients with diffuse large B cell lymphoma(DLBCL).Methods:Retrospective study of clinical characteristics, therapeutic effect, and prognostic factors of newly diagnosed DLBCL elderly patients with an International Prognostic Index(IPI)score≥3 who underwent auto-HSCT in the Affiliated People's Hospital of Ningbo University from January 2015 to August 2020.Results:Among the 31 patients, 18 were males and 13 were females, with a median age of 65(60-75)years.The 13 cases(41.9%)were involved in 2 sites outside lymph nodes, and 13 cases(41.9%)were involved in bone marrow.IPI medium and high risk(IPI=3 points)was found in 21 cases(67.7%), high risk(≥4 points)in 10 cases(32.2%). Before transplantation, 21(67.7%)patients achieved complete remission(CR), and the other 10(32.3%)patients were in the partial remission(PR). All patients after transplantation achieved hematopoietic reconstitution.The median time for neutrophil and platelet engraftment were 10(9-16)days and 12(8-58)days respectively.During a median follow-up of 20.9(3.1 to 73.0)months after transplantation, transplant-related mortality within 100 days was 3.2%(1/31). The 2-year overall survival(OS)and progression-free survival(PFS)were(77.2±8.4)% and(72.7±8.3)%, respectively.Multivariate Cox analysis showed that the achieved partial remission status before auto-hematopoietic stem cell transplantation[OS( HR=30.064, 95% CI: 2.231-405.209, P=0.010), PFS( HR=9.165, 95% CI: 1.926-43.606, P=0.005)], and CD34 + cell count in graft <3×10 6/kg[OS( HR=12.004, 95% CI: 1.234-116.807, P=0.032), PFS( HR=6.115, 95% CI: 1.325-28.221, P=0.020)]were the independent poor prognostic factor affecting both OS and PFS in elderly lymphoma patients. Conclusions:Auto-HSCT may improve the survival rate of carefully selected elderly patients with DLBCL.Pretransplant disease status and the number of CD34 + cells in the graft are important factors to predict the efficiency of auto-HSCT of the patients.

Objective To analyze the characteristics of chronic hepatitis B (CHB) complicated with non-alcoholic fatty liver disease (NAFLD), and to provide countermeasures for the prevention of NAFLD. Methods A total of 348 patients with CHB admitted to our hospital from June 2018 to June 2021 were randomly selected and divided into experimental group (CHB combined with NAFLD, n=195) and control group (CHB, n=153) according to whether they had NAFLD or not. Basic data such as age, sex, BMI (kg/m²), history of diabetes, history of hypertension, and history of alcohol consumption were collected. Serum indexes such as liver function (AST, ALT, GGT, ALP, ALB), blood lipid (TG, ldl-c), fasting blood glucose (FBG) and virological indexes such as hepatitis B virus (HBV DNA) were collected. Results A total of 348 CHB patients were included in the study, including 195 (56.03%) patients with NAFLD. The high NAFLD incidence age was between 30 and 45 years old (163 cases, 46.84%). The incidence of NAFLD in male (131 cases, 70.81%) was significantly higher than that in female (64 cases, 39.26%) (χ²=35.005, P<0.05). The incidence of NAFLD in male patients was significantly higher than that in female patients at age <30 and 30~45 (χ²=10.625, χ²=20.238, P<0.05). There was no significant difference in the incidence rate of NAFLD between men and women at age >45 years (χ²=2.005, P>0.05). There were no significant differences in the history of hypertension, ALT and ALP between the two groups (P>0.05). The differences in age, sex, BMI, history of diabetes, history of alcohol consumption, AST, TG, TG, FBG and FBG between the two groups were statistically different (P<0.05). Logistic regression analysis showed that increased BMI, AST, FBG and LDL were independent risk factors for NAFLD in CHB patients (P<0.05). Conclusions CHB with NAFLD often has glucolipid metabolic disorder, which is related to increased body mass index and AST. It is suggested that we should strengthen the health management of patients with high blood pressure, diabetes, overweight, and obesity, guide patient to balance their diet, adjust their diet structure, control their body weight and glycolipid abnormalities, adjust body fat, reduce blood pressure by drugs, and control blood sugar in a timely manner, and maintain a healthy lifestyle.

Objective:To investigate the patency rates and risk factors of arteriovenous graft (AVG), and provide a clinical guidance for further optimization of vascular access selection and improvement of dialysis quality.Methods:This was a retrospective study. The clinical and follow-up data of patients who received AVG in the Blood Purification Center, First Affiliated Hospital of Zhengzhou University from January 1, 2017 to December 31, 2021 were selected. Kaplan-Meier curve and Cox regression model were used to analyze the patency rates and risk factors of AVG.Results:A total of 381 cases with AVG were included, with 154 cases (40.4%) of males, age of (55.5±11.8) years old, and 140 cases (36.7%) of diabetes. The median time of primary patency was 377.00(95% CI 314.26-439.74) days, and the primary patency rates at 1, 2, and 3 years were 51.0%, 30.7%, and 15.4%, respectively. The median time of primary assisted patency was 839.00(95% CI 668.89-1 009.11) days, and the primary assisted patency rates at 1, 2, and 3 years were 78.3%, 56.4%, and 39.1%, respectively. The secondary patency rates at 1, 2, and 3 years were 96.7%, 90.1%, and 78.5%, respectively. Multivariate Cox regression analysis results showed that anastomotic vein types of basilic vein and cephalic vein (median cubital vein as a reference, HR=1.869, 95% CI 1.124-3.107, P=0.016; HR=2.110, 95% CI 1.176-3.786, P=0.012) and the diameter of anastomotic vein<3.5 mm ( HR=1.411, 95% CI 1.020-1.952, P=0.037) were the independent influencing factors for abnormal primary patency of AVG. Males ( HR=1.680, 95% CI 1.127-2.503, P=0.011), mean arterial pressure<70 mmHg ( HR=3.228, 95% CI 1.109-9.394, P=0.032), Acuseal graft type (Intering as a reference, HR=1.884, 95% CI 1.185-2.994, P=0.007), anastomotic vein type of cephalic vein (median cubital vein as a reference, HR=2.817, 95% CI 1.328-5.977, P=0.007), the diameter of anastomotic vein<3.5 mm ( HR=1.555, 95% CI 1.048-2.306, P=0.028), serum phosphorus ≤1.78 mmol/L (1.13-1.78 mmol/L />1.78 mmol/L, HR=1.737, 95% CI 1.111-2.716, P=0.015;<1.13 mmol/L />1.78 mmol/L, HR=2.162, 95% CI 1.072- 4.362, P=0.031), and ferritin<200 μg/L ( HR=1.850, 95% CI 1.231-2.780, P=0.003) were the independent influencing factors for abnormal primary assisted patency of AVG. Serum albumin<40 g/L ( HR=2.165, 95% CI 1.096-4.275, P=0.026) was an independent influencing factor for abnormal secondary patency of AVG. Conclusions:The primary patency rates of AVG at 1, 2, and 3 years were 51.0%, 30.7%, and 15.4%, respectively. The secondary patency rates of AVG at 1, 2, and 3 years were 96.7%, 90.1%, and 78.5%, respectively. Anastomotic vein types of cephalic vein and basilic vein, and internal diameter<3.5 mm are the independent risk factors for abnormal primary patency of AVG. Anastomotic vein type of cephalic vein and internal diameter<3.5 mm are the independent risk factors for abnormal assisted primary patency of AVG. Serum albumin<40 g/L is an independent risk factor for abnormal secondary patency of AVG. It is suggested that systematic preoperative evaluation and good nutritional status of patients are important to maintain long-term patency of the AVG.

Objective : To investigate the relationship between the 24 h ambulatory blood pressure c ircadian rhythm abnormalities and kidney damage in the patients of lupus nephritis (LN) . Methods : A total of 103 patients with LN patients were enrolled retrospectively. All patients were accepted 24 h ambulatory blood pressure monitoring (ABPM) . The patients were divided into 2 groups according to the 24 h ambulatory blood pressure c ircadian rhythm, including nocturnal blood pressure meaning average declining during the day ( > 10% ) and non⁃dipper type blood pressure group ( < 10% ) . The kidney damage index of LN patients with or without hypertension or nocturnal blood pressure and non⁃dipper type blood pressure was analyzed. The influencing factors of the circadian rhythm of LN blood pressure were analyzed by binary Logistic regression. Results : Among the 103 LN patients, 66 patients were hypertension, 37 patients were none hypertension. Fifty⁃nine patients were non⁃dipper type blood pressure in LN with hypertension group, and 30 patients were non⁃dipper type blood pressure in LN without hypertension. There was no significant difference in the frequency of non⁃dipper type blood pressure between the two groups (81. 1% vs 89. 4% , χ2 = 1. 395, P = 0. 238) . Compared with hypertension group, the levels of serum creatinine (Z = 2. 911, P = 0. 004), urea ( Z = 3. 348, P = 0. 001) and uric acid levels ( t = 2. 017, P = 0. 047 ) were significantly higher than those of LN without hypertension patients, whereas the levels of glomerular filtration rate (eGFR) (Z = 4. 846, P < 0. 001) were significantly lower than those of LN without hypertension patients. In the group of LN with hypertension, the levels of uric acid (Z = 2. 893, P = 0. 004) were significantly higher than those of nocturnal blood pressure subgroup patients compared with no dipper type blood pressure subgroup patients, and the levels of eGFR (Z = 2. 017, P = 0. 0440) were significantly lower. Nevertheless, in the group of LN without hypertension, the kidney damage index had no significant difference between the two subgroups. Univariate and multivariate analysis showed that uric acid was associated with an abnormal rhythm of LN combined with hypertension. Conclusion Abnormal blood pressure rhythms are common in LN patients with or without hypertension. Renal damage significantly increases in the non⁃dipper group of LN compared with hypertension patients.

Objective:To explore the optimal local treatment pattern of supraclavicular lymph node in breast cancer patients with synchronous ipsilateral supraclavicular lymph node metastasis (sISLM).Methods:Clinical data of 128 breast cancer patients with sISLM admitted to the Fourth Hospital of Hebei Medical University from 2010 to 2015 were retrospectively analyzed. Among them, 68 cases were treated with supraclavicular lymph node dissection combined with radiotherapy, and 60 cases received radiotherapy alone. The locoregional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), progression-free survival (PFS) and overall survival (OS) were statistically compared between two groups.Results:Univariate analysis demonstrated that the 5-year LRFS, DMFS, PFS and OS did not significantly differ between two groups (all P>0.05). Multivariate analysis revealed that the local treatment pattern of supraclavicular lymph node was an independent prognostic factor for the 5-year DMFS, PFS and OS (all P<0.05). Subgroup analysis showed that when radiotherapy alone was performed, the 5-year OS of patients in the supraclavicular region radiation dose of>50 Gy group were significantly better than that in the 50 Gy group ( P=0.047). When supraclavicular lymph node dissection combined with radiotherapy was delivered, if the number of dissection was less than 10, the 5-year LRFS, DMFS, PFS, OS of patients in the>50 Gy group were all better than those in the 50 Gy group numerically without statistical significance (all P>0.05). If the number of dissection was ≥10, the 5-year LRFS, DMFS, PFS, OS in the 50 Gy group were better than those in the>50 Gy group numerically, whereas significant difference was only found in the 5-year DMFS ( P=0.028). Conclusions:Supraclavicular lymph node dissection combined with radiotherapy may be the optimal local treatment pattern for supraclavicular lymph node. When radiotherapy alone is performed, a radiation boost to the supraclavicular region may improve OS. When supraclavicular lymph node dissection combined with radiotherapy is performed, if the degree of dissection is low, a radiation boost to the supraclavicular region may bring clinical benefits. However, if the degree of dissection is high, a radiation boost to the supraclavicular region may not bring significant clinical benefits.

Objective: To analyze the molecular characteristics of Listeria monocytogenes strains from ready-to eat food in China. Methods: A total of 239 Listeria monocytogenes strains isolated from ready-to-eat food in 2017, all strains underwent whole-genome sequencing (WGS) , and comparisons uncovered population structure derived from lineages, clonal complex, serogroups, antimicrobial susceptibility and virulence, which were inferred in silico from the WGS data. Core genome multilocus sequence typing was used to subtype isolates. Results: All strains were categorized into three different lineages, lineage Ⅱ was the predominant types in food, and IIa was the main serogroups. CC8, CC101 and CC87 were the first three prevalent CCs among 23 detected CCs, accounting for 49.4%. Only 4.6% (11 isolates) of tested strains harbored antibiotic resistance genes, which were mostly trimethoprim genes (7 isolates, 2.9%). All strains were positive for LIPI-1, and only a part of strains harbored LIPI-3 and LIPI-4, accounting for 13.8% (33 isolates) and 14.2% (34 isolates), respectively. ST619 carried both LIPI-3 and LIPI-4. 51.5% (123 isolates) of strains carried SSI-1, and all CC121 strains harbored SSI-2. Different lineages, serogroups and CCs can be separated obviously through cgMLST analysis, and 24 sublineages were highly concordant with CCs. Conclusion Ⅱa was the main serogroups in ready-to-eat food isolates in China; CC8, CC101 and CC87 were the prevalent CCs, and CC87 isolates was hypervirulent isolates, cgMLST method can be adopted for prospective foodborne disease surveillance and outbreaks detection.
