[Epidemiological investigation and risk factors of diabetic retinopathy in Yunnan Province].

To investigate the prevalence and epidemiological characteristics of diabetic retinopathy (DR) in Yunnan Province, explore its risk factors, and provide a basis for the prevention and treatment of chronic complications of diabetes mellitus (DM). This is a large cross-sectional study, in all, 1 524 DM patients in 16 communities and villages of Yunnan Province who were registered in health service centers were included in this study from August to November 2019. All patients completed a uniform questionnaire, anthropometric measurements, biochemical measurements, and auxiliary examinations. Logistic regression analysis was used to screen the risk factors of DR. The prevalence rates of DR, mild non-proliferative DR (mild-NPDR), and referable DR (RDR) were 16.0% (244/1 524), 4.5% (69/1 524), and 11.5% (175/1 524), respectively. Glycated hemoglobin A1c (HbA1c)≥7.0% was the risk factor of mild-NPDR (OR=1.872, 95%CI 1.055-3.323) and RDR (OR=4.821, 95%CI 2.917-7.969). Blood pressure≥130/80 mmHg (1 mmHg=0.133 kPa) was the risk factor of mild-NPDR (OR=1.933, 95%CI 1.112-3.358) and RDR (OR=1.505, 95%CI 1.063-2.130). In Yunnan Province, 16.0% DM patients had accompanying DR, wherein about 71.7% of them required an ophthalmology referral, and the high incidence of RDR in DM patients was associated with poor control of blood glucose and blood pressure.

[Association between remnant cholesterol levels and incident diabetic retinopathy in middle-aged and older patients with diabetes].

Objective: To investigate the association between remnant cholesterol (RC) and the risk of diabetic retinopathy (DR) in middle-aged and older individuals with diabetes. Methods: Based on the Shanghai Nicheng Cohort Study database, the data of 1 255 individuals with diabetes aged 55-70 years at baseline (2013-2014) with complete fundus photographs and serum cholesterol data in Nicheng, Shanghai, were analyzed. Multinomial logistic regression models were used to evaluate risk ratios (RRs) and their 95% confidence intervals (CIs) between baseline RC level and incident DR. Results: The median age of the subjects was 61.9 years, and 60.4% were women. After a 4.6-year follow-up, 79 (6.3%) patients developed DR, including 50 (4.0%) mild non-proliferative DR and 29 (2.3%) referable DR (RDR). Multivariable logistic regression showed that each mmol/L increase of RC was associated with a 40% higher risk of RDR (RR=1.40, 95%CI 1.03-1.90). Compared with the lowest tertile of RC (<0.63 mmol/L), the risk of RDR in the highest tertile (≥0.85 mmol/L) increased by 4.59 times (RR=5.59, 95%CI 1.51-20.73). Conclusion: The RC level may help identify individuals at high risk of incident RDR in middle-aged and older Chinese adults with diabetes.

Better view by detachable string magnetically controlled capsule endoscopy for esophageal observation: a retrospective comparative study.

Magnetically controlled capsule endoscopy (MCE) system has been used to screen gastric lesions. However, the visualization performance of MCE in the esophagus has not been investigated systematically. String method improved the ability of capsule endoscopy (CE) for esophageal observing; however, the string attachment is complicated and cannot be detached with the CE inside the esophagus. We used a modified string, called detachable string attached to MCE. The aim of the study was to compare the observation performance of MCE with and without the detachable string. A total of 238 participants with upper gastrointestinal symptoms and a healthy check who refused esophagogastroduodenoscopy examination were retrospectively divided into the detachable string MCE group and the MCE alone group from June 2016 to May 2018. A suction cap with a thin, hollow string was attached to the MCE system in the detachable string group. Circumferential visualization of the esophagus including the upper, middle, and lower esophagus and Z-line, and esophageal focal lesion, as well as the recording time, safety and tolerability of the procedure, were assessed. The circumferential visualization of the upper, middle, and lower esophagus and Z-line was more efficient in the detachable string MCE group than in the MCE alone group (P < 0.001). In all, 31 esophageal lesions were detected in the detachable string MCE group, which was more than that in the MCE alone group (10, P < 0.001). The mean recording time was 305 seconds in the string MCE group, which was longer than that in the MCE alone group (48.5 seconds, P < 0.001). In seven participants (6.1%) in the detachable string MCE group, the capsule could not be separated from the string. Detachable string MCE showed better performance in terms of observation of the esophagus. Detachable string MCE can be used to screen for esophageal diseases as an alternative method in the future.

[Prevalence of diabetes and its associated factors in Blang ethnic adults].

Objective: To investigate the prevalence and associated risk factors of diabetes and prediabetes in Blang ethnic adults in Menghai county. Methods: A cross-sectional survey including 3 365 Blang ethnic adults (aged 18 and above from 5 administrative villages) was conducted from February 2017 to March 2017 in Menghai county. A questionnaire, physical examination, and blood assays were included in the survey. Finally, a total of 3 237 adults with complete data were selected into this analysis. Results: The standardized prevalence of diabetes and prediabetes in Blang ethnic adults were estimated based on the sixth national census in 2010. According to the 1999 WHO criteria, the overall standardized prevalence of diabetes and prediabetes were 8.5% (men: 10.2%, women: 6.8%) and 16.1% (men: 18.0%, women: 14.1%), in which the standardized prevalence of newly diagnosed diabetes among the total population was 7.3% (men: 8.7%, women: 5.8%). Multivariable multinominal logistic regression analyses showed that age, hypertension, hypertriglyceridemia, and central obesity were significantly positively associated with both diabetes and prediabetes, with the corresponding odds ratios of 1.74 and 1.37, 2.39 and 2.02, 2.30 and 1.34, 2.55 and 1.73, respectively. Conclusion: The prevalence of diabetes is relatively high in Blang ethnic adults in Menghai county. Improving knowledge of diabetes among the local population is one of key steps in the prevention of diabetes.

[Prevalence and risk factors of diabetes and prediabetes in adults in Jingyuan Ningxia].

Objective: To investigate the prevalence and risk factors of diabetes and prediabetes in Jingyuan County in Ningxia. Methods: A cross-sectional survey including 10 639 participants (18-88 years of age) with a multistage sampling was conducted in Jingyuan County between January, 2014 and April, 2015. Questionnaires, physical examinations, and laboratory tests were included in the survey. Results: Among all the subjects, 10 491 participants (men: 4 826, women: 5 665) with complete data were included in the analysis. The standardized prevalence of diabetes and prediabetes was 4.2% (men: 3.9%, women: 4.5%) and 8.8% (men: 7.6%, women 10.3%), respectively, in which the standardized prevalence of diabetes was higher in Hui (4.5%) than that in Han (3.5%) (P< 0.05). Logistic regression analyses showed that age, family history of diabetes, overweight/obesity, hypertriglyceridemia and hypertension were positively associated with prediabetes and diabetes with the odds ratios being 1.60 and 2.14 (age, P< 0.001), 1.40 and 3.32 (family history, P< 0.05), 1.47 and 1.57 (overweight/obesity, P< 0.001), 1.88 and 2.55 (hypertriglyceridemia, P< 0.001), 1.44 and 1.89 (hypertension, P< 0.001), respectively. Conclusions: The prevalence of diabetes was relatively low in the rural area in Ningxia. However, it is still essential to take active interventions in people at high risk of diabetes in order to prevent the incident diabetes.

[The prevalence of metabolic syndrome among adults in rural areas of Ningxia Hui autonomous region].

Objective: To investigate the prevalence of metabolic syndrome (MS) among adults in rural areas of Ningxia Hui autonomous region. Methods: A cross-sectional study was conducted in 10 639 adults enrolled with a multistage method from Jingyuan County. The MS was identified according to Chinese type 2 diabetes prevention guide (2013). Results: Among all the subjects, 17.4% of them met the MS definition with the standardized prevalence of 14.7% after adjustment of sex and age. The prevalence and standardized rate of MS in men were 19.9% and 17.3%, and in women were 15.3% and 13.5%.The prevalence of MS in men was higher than that in women(P<0.001) and increased with aging in both genders. The prevalence and standardized rate of abdominal obesity, hyperglycemia, hypertension, high triglycerides, and low HDL-C were 19.5% and 16.7%, 15.0% and 12.9%, 42.0% and 37.1%, 25.8% and 23.1%, 28.5% and 27.7%, respectively. The rate of abdominal obesity was higher in women than in men (20.5% vs 18.2%, P=0.004), whereas the rate of hypertension, high triglycerides, and low HDL-C were higher in men than in women (all P<0.01). The prevalence of having one parameter of the MS was 68.4%. Conclusion: The prevalence of MS is higher in rural areas of Ningxia Hui autonomous region, suggesting that a series of comprehensive prevention measures should be carried out to prevent and control the MS so as to improve the public health conditions in rural areas.

[A comparison of clinical characteristics between non-erosive reflux disease and reflux esophagitis].

OBJECTIVE: To summarize the clinical symptoms of patients with non-erosive reflux disease(NERD) and reflux esophagitis(RE), which is helpful to the differential diagnosis. METHODS: Out-patients who met the criteria of NERD or RE according to the Montreal definition in Gastroenterology Department Wuhan Union Hospital from 2010-2014 were enrolled in our study. Clinical data were comprehensively collected. Incidence of disease, severity, frequency of esophageal and extraesophageal symptoms, and the rates of overlapping with functional dyspepsia (FD) or irritable bowel syndrome (IBS) were all studied. RESULTS: Totally 446 subjects were recruited, including 225 patients with NERD and 221 patients with RE. The occurrence rates of esophageal symptoms including heartburn [76.0%(171/225) vs 52.0%(115/221), P<0.01] and acid regurgitation [74.7%(168/225) vs 54.3%(120/221), P<0.05] in NERD group were significantly higher than those in RE patients, with more severe and frequent (P<0.05). Despite the rates of food regurgitation were similar, NERD patients behaved more severely and frequently (P<0.05). Extraesophageal symptoms including throat burning and foreign body sensation in NERD group [40.9%(92/225) vs 27.6%(61/221), 42.2%(95/225) vs 31.7%(70/221), all P<0.05] were also higher than those in RE group, the degree of which was more severe too (P<0.05). RE patients claimed a higher proportion of chronic cough. The incidences of overlapping with IBS in two groups were similar. But there were more patients with FD in NERD group [72.0%(162/225) vs 62.9%(139/221), P<0.05] than in RE group. CONCLUSIONS: The menifestations and degree of esophageal and extraesophageal symptoms in patients with NERD or RE are different, as well as comorbidities such as FD and IBS. These results suggest that NERD and RE are independent diseases.

[Budd-Chiari syndrome with hepatopulmonary syndrome: a case report and literature review].

Objective: To summarize the clinical features and prognosis of Budd-Chiari syndrome with hepatopulmonary syndrome (HPS) in children. Methods: The clinical data of a child who had Budd-Chiari syndrome with HPS treated at the Department of Pediatrics of the First Affiliated Hospital of Zhengzhou University in December 2016 was analyzed retrospectively. Taking "Budd-Chiari syndrome" and "hepatopulmonary syndrome" in Chinese or English as the keywords, literature was searched at CNKI, Wanfang, China Biomedical Literature Database and PubMed up to July 2023. Combined with this case, the clinical characteristics, diagnosis, treatment and prognosis of Budd-Chiari syndrome with HPS in children under the age of 18 were summarized. Results: A 13-year-old boy, presented with cyanosis and chest tightness after activities for 6 months, and yellow staining of the skin for 1 week. Physical examination at admission not only found mild yellow staining of the skin and sclera, but also found cyanosis of the lips, periocular skin, and extremities. Laboratory examination showed abnormal liver function with total bilirubin 53 µmol/L, direct bilirubin 14 µmol/L, and indirect bilirubin 39 µmol/L, and abnormal blood gas analysis with the partial pressure of oxygen of 54 mmHg (1 mmHg=0.133 kPa), the partial pressure of carbon dioxide of 31 mmHg, and the alveolar-arterial oxygen gradient of 57 mmHg. Hepatic vein-type Budd-Chiari syndrome, cirrhosis, and portal hypertension were indicated by abdominal CT venography. Contrast-enhanced transthoracic echocardiography (CE-TTE) was positive. After symptomatic and supportive treatment, this patient was discharged and received oxygen therapy outside the hospital. At follow-up until March 2023, there was no significant improvement in hypoxemia, accompanied by limited daily activities. Based on the literature, there were 3 reports in English while none in Chinese, 3 cases were reported. Among a total of 4 children, the chief complaints were dyspnea, cyanosis, or hypoxemia in 3 cases, and unknown in 1 case. There were 2 cases diagnosed with Budd-Chiari syndrome with HPS at the same time due to respiratory symptoms, and 2 cases developed HPS 1.5 years and 8.0 years after the diagnosis of Budd-Chiari syndrome respectively. CE-TTE was positive in 2 cases and pulmonary perfusion imaging was positive in 2 cases. Liver transplantation was performed in 2 cases and their respiratory function recovered well; 1 case received oxygen therapy, with no improvement in hypoxemia; 1 case was waiting for liver transplantation. Conclusions: The onset of Budd-Chiari syndrome with HPS is insidious. The most common clinical manifestations are dyspnea and cyanosis. It can reduce misdiagnosis to confirm intrapulmonary vascular dilatations with CE-TTE at an early stage. Liver transplantation is helpful in improving the prognosis.

[Study of development of public health safety literacy scale in China].

Objective: To develop a suitable scale for assessing the public health safety literacy in residents in China. Methods: The initial scale of Chinese public health safety literacy was developed through theoretical conceptualization, item pooling, field verifying and item inclusion and exclusion. Then the initial scale was converted into an electronic questionnaire. A total of 2 809 residents from 4 provinces were randomly selected for field testing. Classical test theory (CTT) and item response theory (IRT) were used for item reduction. SPSS 23.0 was used for exploratory factor analysis (EFA) and unidimensional testing. Package R 4.1.1 ltm and mirt were used for the analysis of the psychometric properties of items and generate the ICC, IIC and TIF. Results: The initial scale had 30 items (B1-B30), and the test took 9.8 s to complete one item averagely. According to the CTT, B2 was deleted due to coefficient of total correlation (CITC) <0.3 and the item-dimension correlation coefficient (IDCC) <0.4. B23 was deleted due to CITC<0.3, IDCC<0.4 and difficulty index (W) <0.2. B30 was deleted due to CITC<0.3 and W<0.2. The total Cronbach's α of the scale was 0.923 after deletion. EFA indicated that 14 items should be deleted due to lower factor loadings <0.7. EFA was conducted for remaining 13 items and 2 common factors were extracted, the factor loadings of all items were >0.7, the accumulated variance contribution of the 2 common factors was 63.361%, and the total Cronbach's α was 0.891, showing unidimensionality, IRT was used to test the remaining items. B14 and B20 were deleted due to discrimination coefficient (a) <0.3, difficulty threshold coefficient (b) ∉[-3,3], the small amount of information and the flat, crowded, non-monotonic ICC, and IIC. Finally, the Cronbach's α of the 11-itemed scale was 0.936 with TLI=0.97, CFI=0.99, and RMSEA=0.03. Conclusion: The final scale has good reliability, validity, discrimination, difficulty level and feasibility, and can be applied for the rapid assessment of public health safety literacy in China.
