Objective To investigate the relationship between hemoglobin glycation index(HGI)and metabolic syndrome(MS)and its components.Methods A cross-sectional study was conducted to randomly select 823 patients from the First People's Hospital of Huzhou from September 2022 to September 2023.HGI is calculated based on fasting blood glucose(FPG)and glycosylated hemoglobin(HbA1c)values.The patients were divided into low HGI group(HGI<-0.250%,274 cases),medium HGI group(-0.250%≤HGI≤0.214%,275 cases)and high HGI group(HGI>0.214%,274 cases)by HGI quantile method.The general data and metabolic indexes of each group were compared,and the correlation between HGI and MS and its components was analyzed by multiple Logistic regression.Results With the increase of HGI level,the prevalence rate of MS showed an upward trend(P<0.05).The prevalence rate of MS in low,medium and high HGI groups was 24.8%,42.5%and 55.5%,respectively.Multiple Logistic regression analysis showed that elevated HGI level was risk factor for MS,central obesity,hypertension,hyperglycemia,hypertriglyceridemia and low high-density lipoprotein hyperlipidemia(P<0.05).The risk of MS,central obesity,hypertension,hyperglycemia,hypertriglyceridemia and low high-density lipoprotein hyperlipidemia in high HGI group was 4.005 times(95%CI:2.763-5.808),3.765 times(95%CI:2.604-5.443),1.596 times(95%CI:1.089-2.337),2.655 times(95%CI:1.809-3.895),2.024 times(95%CI:1.404-2.918)and 2.247 times(95%CI:1.537-3.284)of that in low HGI group,respectively.Conclusion HGI is related to MS and its components,and HGI may be a new indicator to prevent and monitor MS.

Objective:To examine the burden and trends of acute viral hepatitis in Guangdong Province from 1990 to 2019, and provide reference evidences for hepatitis prevention and control in the province.Methods:Data on acute viral hepatitis (hepatitis A, B, C, and E) in Guangdong from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The incidence, prevalence, mortality, and disability-adjusted life years (DALY) data were analyzed by age and gender, and the estimated annual percentage change (EAPC) was calculated to describe the changing trends in disease burden.Results:From 1999 to 2019, the standardized incidence, prevalence, mortality, and DALY of acute viral hepatitis in Guangdong were higher than the national averages. In 2019, 51.43% (2 245 087/4 365 221) of acute viral hepatitis cases in Guangdong Province were mainly attributed to hepatitis B, and 77.18% (106/138) of deaths were due to acute hepatitis B. In different age groups, except for acute hepatitis B, which was more common in adults, the incidence rates of other types of viral hepatitis such as hepatitis A, B, and E showed an overall decreasing trend with age. The mortality rates of different types of acute viral hepatitis, except for the <5 age group, increased with age. The overall incidence and mortality rates of acute viral hepatitis were higher in men than in women.Conclusions:The overall burden of acute viral hepatitis in Guangdong declined in 2019, but remained higher than the national level. Further efforts are needed to strengthen hepatitis prevention and screening in different population in Guangdong Province, especially in children and the elderly.

Objective:To observe the clinical characteristics and guideline compliance of chronic obstructive pulmonary disease (COPD) patients with initial triple therapy in real-life world.Methods:This study is a cross-sectional study. The subjects of the study were COPD patients admitted to 13 hospitals in Hunan Province and Guangxi Zhuang Autonomous Region from December 2016 to December 2021. The initial treatment was triple inhaled drugs. The data collected included gender, age, diagnosis, body mass index (BMI), history of acute exacerbation (AE) in the past year, pulmonary function, COPD Assessment Test (CAT) score, modified British Medical Research Council Dyspnea Questionnaire (mMRC), inhaled drugs and other indicators. The characteristics and differences of COPD patients before and after 2020 were analyzed.Results:7 184 patients with COPD were enrolled in this study, including 2 409 COPD patients treated with initial triple therapy, accounting for 33.5%(2 409/7 184). Taking January 1st, 2020 as the cut-off point, 1 825 COPD patients (75.8%) received initial treatment with triple inhaled drugs before 2020 and 584 patients (24.2%) after 2020 were included in this study. Compared with COPD patients before 2020, the COPD patients after 2020 had higher FEV 1% [(40.9±15.5 )% vs (39.3±15.5)%, P=0.040], lower CAT [(15.8±6.5)point vs (17.5±6.2)point, P<0.001], less AE in the past year [1(0, 2)times vs 1(0, 2)times, P=0.001] and higher rate of non-AE [255(43.7%) vs 581(37.1%), P=0.006]. In addition, before 2020, patients with COPD were mainly treated with open triple drugs (1 825/1 825, 100%); after 2020, 306 patients (52.4%) received open triple inhaled drugs, and 278 patients (47.6%) received closed triple inhaled drugs. Conclusions:In real-life world, most of patients with COPD treated with triple therapy have severe lung function, obvious symptoms and high risk of acute exacerbation. The real-world prescribing of triple therapy in patients with COPD does not always reflect recommendations in guidelines and strategies, and overtreatment is common. After 2020, prescribing triple therapy for COPD patients is more positive and worse consistency with guideline.

Objective:To compare and analyze the value of X-ray examination and MRI in the diagnosis of subacromial impingement syndrome.Methods:Sixty patients with shoulder pain and weakness in Beijing Tiantan Hospital, Capital Medical University from January 2019 to May 2021 were selected. All patients underwent X-ray and MRI. Taking clinical diagnosis as the gold standard, the diagnostic efficacy of X-ray and MRI in subacromial impact syndrome was compared and analyzed.Results:The consistency between MRI and gold standard was good ( Kappa = 0.769, P<0.01), and the consistency between X-ray and gold standard was general ( Kappa = 0.464, P<0.01); there was no significant difference between X-ray examination and MRI examination of acromion morphological classification, subacromial space classification ( P>0.05); The sensitivity of MRI was higher than that of X-ray, and the difference was statistically significant ( χ2 = 4.00, P<0.05). There was no difference between MRI and X-ray, and the difference was not statistically significant ( χ2 = 0.25, P>0.05). Conclusions:X-ray and MRI are complementary to each other in the diagnosis of subacromial impingement syndrome. X-ray examination should be carried out first, and MRI should be carried out when necessary.

Objective:To describe the baseline characteristics of the subjects enrolled in the China Quantitative CT (QCT) big data program in 2018—2019.Methods:Based on baseline data from the Chinese health big data project from January 2018 to December 2019 from the eligible enrolled population, measurements of bone mineral density (BMD) and visceral adipose tissue (VAT) were performed using Mindways′ QCT Pro Model 4 system. The baseline data of age, gender, regional distribution, height, weight, abdominal circumference, blood pressure, blood routine and blood biochemical tests were analyzed. And the single factor analysis of variance (ANOVA) was used to check the age related trend of BMD and VAT in both genders.Results:After screening the inclusion exclusion criteria and outliers of the main indicators, 86 113 people were enrolled in the project. The enrollment rate was 92.47%, including 35 431 (41.1%) women and 50 682 (58.9%) men, and the ratio of men to women was 1.43. The mean age was (50.3±12.7) years in all the subjects, and it was (50.2±12.8) years and (50.4±12.5) years in men and women, respectively, and there was no statistical difference between the two genders ( P>0.05). Total of 43 833 people were enrolled in east China, it was the largest group by region (50.90%), it was followed by central China (16 434 people, 19.08%), and the number of people enrolled in Northeast China was the lowest (2 914 people, 3.38%). The rate of completing of health information indicators related to the main outcome of the study were all above 70%, and there were significant differences between men and women (all P<0.05). The mean BMD was (139.33±46.76) mg/cm 3 in women, (135.90±36.48) mg/cm 3 in men, which showed a decreasing trend with age in both gender (both P<0.001); the mean intra-abdominal fat area was (116.39±56.23) cm 2 in women, (191.67±77.07) cm 2 in men, and there was an increasing trend with age in both men and women (both P<0.001). Conclusions:There are gender differences in BMD and VAT measured by QCT with different age tendency, and there are gender differences in health information index. Regional factors should also be taken into account for regional differences in the inclusion of data.

Although different types of drugs are available for postmenopausal osteoporosis, the limitations of the current therapies including drug resistances and adverse effects require identification of novel anti-osteoporosis agents. Here, we defined that norlichexanthone (NOR), a natural product, is a ligand of estrogen receptor-alpha (ER

Objective:To investigate the prognosis after salvage radiotherapy with or without hormone therapy for prostate cancer.Methods:From May 2014 to December 2020, 248 patients undergoing salvage radiotherapy due to prostate-specific antigen (PSA)persistence or biochemical progression after radical prostatectomy at Sun Yat-sen University Cancer Center (n=157) and West China Hospital, Sichuan University (n=91) were analyzed. Median age was 66 (45-78) years old. Median PSA was 23.50 (0.18-845.00) ng/ml. The number of PSA persistence and biochemical progression were 143 (59%) and 105 (42%). The number of pT 2, pT 3a, pT 3b, pT 4, and unknown T stage was 99, 49, 78, 15 and 7 cases.The number of N 0, N 1 and unknown N stage was 153, 44 and 51 cases. 165 cases had positive surgical margin. Gleason score of 6, 7, 8, >8 score and unknown was in 12, 104, 34, 90 and 8 patients. Early and late salvage radiotherapy was performed in 117 and 131 patients, and 70 patients (28%) were CRPC. Hormone therapy was used combined with radiotherapy in 182 patients (73%). PSA decline after radiotherapy was compared with Chi-squre test. Kaplan-Meier method and log-rank test were used to compare progression free-survival (PFS)after radiotherapy. Univariate and multivariate analyses of PFS were performed using Cox proportional hazards model. Early salvage radiotherapy was defined as PSA≤0.5 ng/ml before radiotherapy, and late salvage radiotherapy was defined as PSA>0.5ng/ml. Results:PSA response (PSA decline ≥50%) rate was 94% (233/248), and 82% (203/248) patients had PSA decline ≥ 90%. Twelve (5%) patients had rising PSA after completing radiotherapy, but only 4 (2%) had real progression. The median PFS was 69 months (95% CI 68-70), and 3-year and 5-year PFS rate were 80% and 67%. PFS of PSA persistence and biochemical progression were similar ( HR =0.71, 95% CI 0.37-1.37, P=0.311). Compared with late salvage radiotherapy, early salvage radiotherapy had better PFS [69 (95% CI 68-70) vs. 59 (95% CI 44-74) months, P<0.001]. Compared with hormone sensitive, castration-resistant was associated with worse PFS (5-year PFS rate 74% vs. 51%, P<0.001). In multivariate analysis, Gleason score>8, castration-resistant and late salvage radiotherapy were unfavorable prognostic factors. Conclusions:In patients receiving salvage radiotherapy with or without hormone therapy for PSA persistence and biochemical progression after radical prostatectomy, high PSA level before radiotherapy and castration resistant is associated with poor prognosis.

Objective: To predict the efficacy of endoscopic tissue adhesives in the treatment of gastric varices in patients with liver cirrhosis by Nomogram model. Methods: From August 2014 to September 2017, 158 patients with liver cirrhosis caused esophagogastric variceal bleeding and received endoscopic tissue adhesives treatment at Zhongshan Hospital, Fudan University were collected. All patients were followed for 12 months. The primary outcome was rebleeding. The factors of rebleeding after endoscopic treatment of esophagogastric varices were analyzed. Nomogram prognostic model was developed and compared with Child-Pugh grading, computed tomography angiography (CTA) and hepatic venous pressure gradient (HVPG) in prognostic accuracy in rebleeding after endoscopic treatment in liver cirrhosis caused esophagogastric varices. Univariate and multivaricate Cox regression analysis, Kaplan-Meier curve and log-rank test were performed for statistical analysis. Results: During the follow-up, rebleading occurred in 18 cases (11.4%), 37 cases (23.4%) and 49 cases (31.0%) at 2, 6, and 12 months after endoscopic treatment. The results of univariate Cox regression analysis showed the risk factors of rebleeding after endoscopic treatment of gastric varices included gender, alcoholic liver cirrhosis, diabetes mellitus, Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence vs. absence) HVPG (<16 mmHg vs. ≥16 mmHg, 1 mmHg = 0.133 kPa), extensive portal embolism, esophageal varices, type 2 gastric varices, injection points of tissue adhesive (≤3 points vs. > 3 points), injection volume of tissue adhesive (≤ 3 mL vs. > 3 mL) (hazard ratio (HR)=0.575, 2.018, 1.562, 3.433, 2.945, 1.859, 2.743, 0.324, 1.840, 1.477, and 1.716; 95% confidence interval (CI) 0.305 to 1.084, 0.902 to 4.514, 1.753 to 6.724, 1.663 to 5.217, 1.012 to 3.415, 0.852 to 8.830, 0.079 to 1.335, 1.012 to 3.317, 0.839 to 2.602, and 0.935 to 3.152; all P<0.2). The results of multivariate Cox regression analysis indicated that Child-Pugh grade, extraluminal vessels by CTA, and HVPG (HR = 2.095, 95% CI 1.099 to 3.995, P = 0.025) were all independent risk factors of rebleeding after endoscopic treatment of gastric varices (HR=2.665, 2.886, and 2.095; 95% CI 1.339 to 5.300, 1.580 to 5.271, and 1.099 to 3.995; all P<0.05). Kaplan-Meier curves showed that Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence or absent) and HVPG (<16 mmHg vs. ≥16 mmHg) could effectively predict cumulative non-rebleeding rate in one year after endoscopic treatment of gastric varices, and the differences were statistically significant (all P<0.05). Receiver operataring characteristic curve analysis demonstrated that the predictive value of the model combined with Child-Pugh grade, extraluminal vessels on CTA and HVPG was higher than that of Child-Pugh grade and HVPG (AUC=0.746, 0.673 and 0.585; 95% CI 0.662 to 0.829, 0.583 to 0.762, and 0.486 to 0.683; P<0.01, P=0.001 and P=0.089, respectively). Patients were divided into low, medium, and high-risk groups according to the 25th and 75th percentiles of the Nomogram score. The results showed that Nomogram model could effectively distinguish high-risk groups of rebleeding after endoscopic treatment of gastric varices, and the difference was statistically significant (P <0.01). Conclusions Extraluminal vessels on CTA, HVPG and Child-Pugh grade are independent prognostic evaluation indexes of rebleeding after endoscopic treatment of gastric varices. The predictive accuracy of Nomogram model based on these three prognostic factors may be better than Child-Pugh grade and HVPG.

Objective:To investigate the work engagement among nurses in stomatology hospital and to analyze its influencing factors.Methods:From September 2018 to October 2018, we selected 229 medical and nursing personnel from a Class Ⅲ Grade A public stomatology hospital as the research object by convenience sampling. All medical and nursing personnel were investigated with the self-designed Work Engagement Scale for Dental Specialist Outpatient Nurses to analyze the current status and influencing factors of work engagement among outpatient nurses in stomatology hospital.Results:134 doctor questionnaires were distributed and 126 valid questionnaires were returned; 113 nurse questionnaires were distributed and 103 valid questionnaires were collected.Totals of 50.8% (64/126) of doctors and nurses were reasonably staffed; 45.6% (47/103) of nurses were satisfied with the professional status and development. The three items with the highest engagement evaluated by doctors included mixing materials, use of instruments and disinfection of products after use; the three items with the lowest engagement evaluated by doctors were medical record data management, assisting doctor-patient communication and return visits. Univariate analysis showed that there was a statistical difference in the engagement among nurses with different departments ( P<0.05) . Correlation analysis indicated that the staffing status of nurses is positively correlated with the clinical cooperation of nurses and the degree of participation in hospital prevention and control ( P<0.05) ; the professional status and development of nurses are positively correlated with the degree of patient participation management ( P<0.05) ; the degree of salary satisfaction is positively correlated with the degree of patient participation and clinic management. Conclusions:Nurses of public stomatology hospital have low overall work engagement during diagnosis and treatment for patients. We need to strengthen dental nursing training. Nurse staffing in place and perfecting performance evaluation methods can promote nurses to fully perform their duties and promote the improvement of patient safety.

Objective: To evaluate the post-marketing safety profiles of the inactivated enterovirus type 71 (EV-A71) vaccine (Vero cell) after routine inoculation. Methods: Eleven cities of Zhejiang Province, Fengtai district of Beijing, Qinnan district, two counties as Pingle and Pingguo of Guangxi Zhuang Autonomous Region, and Dongtai city of Jiangsu Province were selected as the field sites. A total of 45 239 subjects were enrolled in this study from children who seeked the vaccination of EV-A71 vaccine during the period from July, 2016 to June, 2018. Different sampling method were adopted in different sites. All vaccinated children were invited to participate in the study in Fengtai and Dongtai, however, systematic sampling method were adopted in other sites. Active surveillance was conducted and information about adverse reactions (ARs) occurred in 30 min, 3 d and 30 d following each dose of EV-A71 immunization was collected by field observation, phone-call or face-to-face interview. The incidence of ARs in different types, symptoms and grades were described. Results: In total, there were 45 239 children who received 71 243 doses EV-A71 vaccine. The overall incidence of ARs was 1.079% (769 doses), with the highest incidence of 1.182% (177/14 973) in 5-11 month group and the lowest incidence of 0.849% (18/2 119) in ≥ 36 month group among different age groups. There was a higher incidence in solicited ARs, which was 1.047% (746 doses). The incidences of grade 1 and grade 2 ARs were also higher, which were 0.404% (288 doses) and 0.554% (395 doses), respectively. No grade 4 ARs occurred. The doses of the first and the second vaccination was 40 736 and 30 507, respectively, and the incidences of ARs were 1.281% (522 doses) and 0.810% (247 doses). Also, the incidences of ARs were 0.091% (37 doses) and 0.043% (13 doses) in local, and 1.168% (476 doses) and 0.760% (232 doses) in system. The symptoms of ARs after the two doses of vaccination were basically the same. Redness at the injection site was the most common local ARs after each dose vaccination, with doses of 24 and 11, while fever was the most common systemic ARs, with doses of 362 and 190. Moreover, ARs mainly occurred in 30 min to 3 d after each dose vaccination, with incidence of 1.016% (414 doses) and 0.698% (213 doses) in the first and second dose, respectively. Conclusion The ARs had a low incidence after vaccination in children and most were mild or moderate. EV-A71 vaccine with good safety is suitable for inoculation in a large scale.
