Cardiovascular risk assessment is a basic tenet of the prevention of cardiovascular disease. Conventional risk assessment models require measurements of blood pressure, blood lipids, and other health-related information prior to assessment of risk via regression models. Compared with traditional approaches, fundus photograph-based cardiovascular risk assessment using artificial intelligence (AI) technology is novel, and has the advantages of immediacy, non-invasiveness, easy performance, and low cost. The Health Risk Assessment and Control Committee of the Chinese Preventive Medicine Association, in collaboration with the Chinese Society of Cardiology and the Society of Health Examination, invited multi-disciplinary experts to form a panel to develop the present consensus, which includes relevant theories, progress in research, and requirements for AI model development, as well as applicable scenarios, applicable subjects, assessment processes, and other issues associated with applying AI technology to assess cardiovascular risk based on fundus photographs. A consensus was reached after multiple careful discussions on the relevant research, and the needs of the health management industry in China and abroad, in order to guide the development and promotion of this new technology.

Objective:To investigate the prevalence of Helicobacter pylori infection among family members, and analyze associated risk factors. Methods:The current investigation was a cross-sectional study. The Qinghai region was stratified into urban areas, agricultural areas, and pastoral areas. The urban areas of Xining City, the agricultural areas of Haidong City, and the pastoral areas of Haibei Tibetan Autonomous Prefecture were selected. A total of 396 resident families (1 131 people) who underwent health checkups from 2021 to 2022 in the above areas were included in the survey study. Questionnaires were administered and H. pylori infection was detected using the 13C-urea breath test. Numerical data were expressed as cases and percentages, and the Chi-square test was used to compare differences in H. pylori infection rates in the populations and families in each group. Multifactorial logistic regression was used to analyze risk factors for H. pylori infection, and P<0.05 was considered statistically significant. Results:The prevalence of H. pylori infection in Qinghai province was 52.8% (597/1 131) and the prevalence of H. pylori infection in households was 80.6% (319/396). In H. pylori-positive households with at least 1 infected spouse, 40.4% (36/89) had only 1 infected spouse, and in 59.6% (53/89) both spouses were infected. In analysis of children infected by parents with H. pylori, 20.0% (9/45) of households had fathers and children infected, 48.9% (22/45) had mothers and children infected, and 31.1% (14/45) had both parents and children infected. In univariate analysis there was a statistically significant difference in the overall comparison of H. pylori infection rates among families with different numbers of people living together ( χ2=11.12, P=0.004), and between-group comparisons suggested that H. pylori infection rates were higher in families with 4 or 5 people and more than 5 people living together than in families with 2 or 3 people living together. The H. pylori infection rate was higher in families that did not use serving chopsticks and spoons during family meals than in families that did use serving chopsticks and spoons ( χ2=6.12, P=0.013). In multifactorial logistic regression analyses the number of people living together in a family and whether or not serving chopsticks and spoons were used at family meals were associated with H. pylori infection ( P<0.05). Conclusion:The H. pylori infection rate in families in Qinghai Province is high, and there is a clear association with family aggregation. It is more common for both members of a couple to be infected, and H. pylori infection of a mother has a greater effect on the children′s infection status than H. pylori infection of a father. The infection rate of H. pylori was lower in families that used serving chopsticks and spoons during dinner gatherings, and the fewer the number of people living together in the family, the lower the H. pylori infection rate.

Objective:To compare the clinical benefits of classic endoscopic submucosal dissection (ESD) and hybrid ESD for the treatment of colorectal epithelium-derived tumors.Methods:The current investigation was a retrospective multicenter study of 418 patients who underwent ESD between January 2015 and April 2021 at Beijing Jishuitan Hospital. The patients were assigned to one of two groups based on the surgical procedure they underwent; a classic ESD group or a hybrid ESD group. The primary outcome was the rate of en bloc resection and complete resection. SPSS 26.0 was used for statistical analysis. Homogeneity of variance was assessed via Cochran′s test. Normally distributed data with homogeneity of variance were analyzed via the t-test for independent samples. Non-normally distributed data and data with unequal variance were analyzed via the Kruskal-Wallis non-parametric test. Categorical data were analyzed via the Chi-square test or Fisher′s exact test. Multivariable assessment was performed via logistic regression analysis. Results:The en bloc resection rates [89.4% (84/94) vs. 87.0% (194/223), χ2=0.34, P=0.558] and complete resection rates [85.1% (80/94) vs. 82.1% (183/223), χ2=0.33, P=0.510] were similar. Compared with classic ESD, procedures were shorter in the hybrid ESD group [22(7, 213) vs. 47(12, 680) min, Z=0.23, P<0.001], dissection was completed more rapidly [0.14(0.02, 0.32) vs. 0.10(0.02, 0.41) cm 2/min, Z=0.08, P<0.001], and there was a higher rate of perforation (9.6% vs. 2.2%, χ2=2.67, P=0.006). Laterally spreading tumor granular type nodular mixed, non-granular type pseudo-depressed, flat-elevated type (odds ratio 2.826, P=0.012), and tumor location (odds ratio 6.970, P=0.005) were independently associated with complete resection in the hybrid ESD group. Conclusion:Classic ESD and hybrid ESD had similar en bloc and complete resection rates for colorectal epithelium-derived tumors, but hybrid ESD had shorter operation times. With respect to hybrid ESD, factors associated with failure of complete resection included lesion type and crossing tissue boundaries.

Objective:To investigate the clinical and pathological characteristics of chronic hepatitis B (CHB) with metabolic dysfunction-associated fatty liver disease (MAFLD), as well as associations with advanced fibrosis.Methods:CHB patients who underwent liver biopsy at Tianjin Second People′s Hospital from June 2016 to September 2019 were included in the study. The patients were divided into two groups based on whether they had concomitant MAFLD; a CHB group and a MAFLD-CHB group. t-tests and Chi-square tests were used to compare pathological characteristics and basic features in the two groups. Logistic regression analysis was used to analyze factors associated with advanced fibrosis. Results:The CHB group included 110 patients, and the MAFLD-CHB group included 272 patients. There were significant differences in smoking, alcohol consumption, hypertension incidence, body metabolic index, alanine aminotransferase, gamma-glutamyl transferase (GGT), high-density lipoprotein, low-density lipoprotein, fasting plasma glucose, and platelets (PLT) between the two groups (all P<0.05). The MAFLD-CHB group had a higher incidence of advanced fibrosis than the CHB group ( P<0.05). In logistic regression analysis MAFLD [odds ratio ( OR)=2.204, 95% confidence interval ( CI) 1.018-4.774, P=0.045], GGT ( OR=1.008, 95% CI 1.002-1.013, P=0.005), and PLT ( OR=0.995, 95% CI 0.991-0.999, P=0.019) were associated with advanced fibrosis (all P<0.05). In the MAFLD-CHB group type 2 diabetes ( OR=3.281, 95% CI 1.375-7.832, P=0.007), GGT ( OR=1.011, 95% CI 1.003-1.018, P=0.005), and PLT ( OR=0.993, 95% CI 0.988-0.998, P=0.004) were associated with advanced fibrosis ( P<0.05). Conclusion:Patients with MAFLD-CHB are more likely to develop advanced fibrosis than patients with CHB alone. In the MAFLD-CHB group type 2 diabetes mellitus was associated with advanced fibrosis. It is important to strictly control relevant risk factors in MAFLD-CHB patients, especially in patients with type 2 diabetes.

Objective:Gastric adenocarcinoma of the fundic gland type (GA-FG) is rare and often occurs in patients who are not infected with Helicobacter pylori. The current study analyzed and summarized the clinical, endoscopic, and pathological features of GA-FG, in an effort to improve its diagnosis. Methods:Patients who were diagnosed with GA-FG and treated with endoscopic submucosal dissection (ESD) resection at the Department of Gastroenterology, First Affiliated Hospital of Zhejiang Chinese Medical University from January 1st 2020 to October 1st 2022 were included in the study. Their clinical manifestations, endoscopic features, pathological immunohistochemistry, and other characteristics were analyzed.Results:A total of 14 patients with GA-FG were included in the study, 5 males and 9 females, with a mean age of 59 years. Most had no substantial clinical manifestations. Twelve patients were H. pylori-negative, all patients underwent ESD resection, and all patients survived during the follow-up period of 13±9 months. Eleven patients had postoperative endoscopic follow-up records, and no recurrence was detected. Fifteen lesions were detected (2 were present in 1 patient). Twelve were located in the upper 1/3 of the stomach, 10 were ≤ 1 cm in diameter, 12 had a morphology of type 0-Ⅱa, 8 had visible discoloration changes, and 12 had visible vasodilation on the surface. Magnified endoscopy and narrow-band imaging indicated that 12 of the lesions had enlarged marginal crypt epithelium, without any obvious microvascular pattern abnormalities and no obvious borderline. After resection the pathological specimens were all without vascular infiltration, and there was no atrophy of the mucosa at the edge of the lesion. In immunohistochemistry analyses MUC-2 was negative in all cases. MUC5AC was negative in 11 cases, MUC-6 was positive in all cases, and Ki-67 was ≤ 5% in 12 cases. Conclusions:GA-FG is a newly identified type of gastric cancer with low malignancy and a good prognosis. Characteristic discoloration and surface dilated vessels are often evident endoscopically. Enlarged marginal crypt epithelium and no visible boundary lines are often apparent in magnification endoscopy and narrow band imaging.

Objective:To investigate the appropriate cut-off for diagnosis of primary aldosteronism (PA) by seated saline suppression test (SSST) based on liquid chromatography with tandem mass spectrometry (LC-MS/MS).Methods:In this cross-sectional study, patients who underwent SSST for suspected PA in the First Affiliated Hospital of Chongqing Medical University from January 2018 to March 2022 were evaluated. Briefly, 300 patients with PA and 119 with essential hypertension (EH) were included. Plasma aldosterone concentration (PAC) after SSST was determined by LC-MS/MS. Primary aldosteronism confirmatory testing (PACT) score was used as the reference standard for diagnosis of PA, and receiver operating characteristic (ROC) curve was used to explore the cut-off value.Results:The average age of the PA group was (50.8±10.5) years, and males accounted for 53.00% ( n=159); the average age of the EH group was (49.4±11.2) years, and males accounted for 26.89% ( n=32). The area under the ROC curve of PAC post-SSST was 0.819 (95% CI 0.775-0.862). When 40 pg/ml (110.8 pmol/L) was selected as the appropriate cut-off for diagnosis of PA, the sensitivity was 83.67% (95% CI 78.88%-87.56%) and specificity was 60.50% (95% CI 51.10%-69.21%). Thus, 95.09% (155/163) of patients with unilateral PA could be identified. Conclusion:PAC after SSST determined by LC-MS/MS has high efficacy for diagnosis of PA, and 40 pg/ml is recommended as the appropriate cut-off value.

Objective:To compare the short-term efficacy and the safety of microwave ablation (MWA) and radiofrequency ablation (RFA) in the treatment of benign thyroid nodules (BTNs).Methods:This prospective randomized controlled trial, performed from December 2019 to September 2021, included 36 patients with solid or predominantly solid BTNs who met the eligibility criteria and provided written informed consent at the Nanjing sub-center (Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine). Patients were assigned to either the MWA group or the RFA group (18 patients in each group) at a ratio of 1∶1 using a block randomization design and allocation concealment using sealed envelope randomization. The independent-sample t-test and χ2 test were used to compare the volume reduction rates (VRRs), effective rates (VRRs≥50%), cosmetic scores, and complication rates at 1, 3, and 6 months after treatment between the two groups. Results:The clinical characteristics of the two groups of patients were comparable. After ablation, the nodule volume was significantly reduced in both groups. At 1, 3, and 6 months, there was no significant difference in the volume between the two groups (all P>0.05). At 3 months, the RFA group had a larger VRRs than that in the MWA group (62.08%±12.46% vs. 46.90%±23.16%, t=-2.45, P=0.021). However, at 1 and 6 months, no statistical significance was observed (both P>0.05). No significant difference was observed in the effective rates at the last follow-up (14/18 vs. 18/18, P=0.104). However, the RFA group had a lower cosmetic score than that in the MWA group (1.78±0.43 vs. 2.17±0.51, t=-2.47, P=0.019). There was no statistically significant difference in the complication rates between the two groups (all P>0.05). Conclusions:Both MWA and RFA were effective and safe treatments for BTNs, with no significant differences in short-term efficacy and safety. In addition, the RFA group showed slightly more favorable outcomes than the MWA group in terms of cosmetic improvement.

Objective:To verify the predictive value of the Second Revision of the International Staging System (R2-ISS) in newly diagnosed patients with multiple myeloma (MM) who underwent first-line autologous hematopoietic stem cell transplantation (ASCT) in a new drug era in China.Methods:This multicenter retrospective cohort study enrolled patients with newly diagnosed MM from three centers in China (Beijing Chao-Yang Hospital, Capital Medical University; the First Affiliated Hospital, Sun Yat-Sen University, and the Second Affiliated Hospital of Naval Medical University) from June 2008 to June 2018. A total of 401 newly diagnosed patients with MM who were candidates for ASCT were enrolled in this cohort, all received proteasome inhibitor and/or immunomodulator-based induction chemotherapy followed by ASCT. Baseline and follow-up data were collected. The patients were regrouped using R2-ISS. Progression-free survival (PFS) and overall survival (OS) were analyzed. The Kaplan-Meier method was used to analyze the survival curve and two survival curves were compared using the log-rank test. Cox regression analysis were performed to analyze the relationship between risk factors and survival.Results:The median age of the patients was 53 years (range 25-69 years) and 59.5% (240 cases) were men. Newly diagnosed patients with renal impairment accounted for 11.5% (46 cases). According to Revised-International Staging System (R-ISS), 74 patients (18.5 %) were diagnosed with stage Ⅰ, 259 patients (64.6%) with stage Ⅱ, and 68 patients (17.0%) with stage Ⅲ. According to the R2-ISS, the distribution of patients in each group was as follows: 50 patients (12.5%) in stage Ⅰ, 95 patients (23.7%) in stage Ⅱ, 206 patients (51.4%) in stage Ⅲ, and 50 patients (12.5%) in stage Ⅳ. The median follow-up time was 35.9 months (range, 6-119 months). According to the R2-ISS stage, the median PFS in each group was: 75.3 months for stage Ⅰ; 62.0 months for stage Ⅱ, 39.2 months for stage Ⅲ, and 30.3 months for stage Ⅳ; and the median OS was not reached, 86.6 months, 71.6 months, and 38.5 months, respectively. There were statistically significant differences in PFS and OS between different groups (both P<0.001). Multivariate Cox regression analysis showed that stages Ⅲ and Ⅳ of the R2-ISS were independent prognostic factors for PFS ( HR=2.37, 95% CI 1.30-4.30; HR=4.50, 95% CI 2.35-9.01) and OS ( HR=4.20, 95% CI 1.50-11.80; HR=9.53, 95% CI 3.21-28.29). Conclusions:The R2-ISS has significant predictive value for PFS and OS for transplant-eligible patients with MM in the new drug era. However, the universality of the R2-ISS still needs to be further verified in different populations.

We aimed to analyze the clinical data of 10 patients (6 male and 4 female) with Fabry disease (FD). The mean age of the patients was (28.80±9.27) years. Seven patients had classical FD and three had delayed onset FD. Among the 10 patients, six had skin involvement and cutaneous angiokeratoma; five had hypohidrosis or anhidrosis; nine had intermittent neuralgia; and three had supraorbital ridge protrusion, forehead bulge, and lip thickening. Five patients had proteinuria, including one with chronic kidney disease stage 3 and one with chronic kidney disease stage 5. Cardiac involvement occurred in three patients, two had myocardial hypertrophy and one had valvular insufficiency. The activity of galactosidase decreased in seven patients (2.80-1.55 μmol·L -1·h -1). Plasma deacetyl-GL-3 was elevated in all 10 patients(3.12-120.00 ng/ml). Three patients underwent renal biopsy, wherein two cases of focal segmental glomerulosclerosis and one of mesangial proliferative glomerulonephritis was found. A large number of myeloid and zebra bodies were found in the podocytes in three patients, including a small number of myeloid and zebra bodies in the renal tubular epithelial cells in one patient with occasional zebra bodies in the renal interstitium. Nine patients had GLA gene mutations. One patient was c.102T>A, a de novo mutation. Four patients were treated with agalsidase α injection (0.2 mg/kg, intravenous infusion every 2 weeks), and their prognosis was good. FD has various clinical manifestations and multi-system involvement, which requires multidisciplinary cooperation. Detection of galactosidase activity, plasma globotriaosylsphingosine, and GLA gene mutation can help for accurate diagnosis.
