Objective To investigate the correlation between serum long non-coding RNA FGD5-AS1(ln-cRNA FGD5-AS1),microRNA-103a-3p(miR-103a-3p)and puerperal infection(PI)in patients with gesta-tional diabetes mellitus(GDM)in late pregnancy.Methods A total of 168 late pregnancy GDM patients who were hospitalized and delivered in the hospital from January 2022 to June 2023 were retrospectively selected as the experimental group,and the patients were separated into an infected group(96 cases)and an uninfected group(72 cases)based on whether they had PI.At the same time,120 late pregnant women who underwent prenatal examination in the hospital and had normal gestational blood glucose were selected as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)was applied to detect the expression levels of ln-cRNA FGD5-AS1 and miR-103a-3p.Multivariate Logistic regression was applied to analyze the influencing factors of PI in late pregnancy GDM patients.StarBase website was applied to analyze the relationship between lncRNA FGD5-AS1 and miR-103a-3p.Pearson was applied to analyze the correlation between lncRNA FGD5-AS1 and miR-103a-3p.Receiver operating characteristic(ROC)curve was applied to evaluate the value of ln-cRNA FGD5-AS1 and miR-103a-3p in predicting the occurrence of PI.Results There was a statistically sig-nificant difference in the expression levels of serum lncRNA FGD5-AS1 and miR-103a-3p between the experi-mental group and the control group(P＜0.05),the expression level of serum lncRNA FGD5-AS1 in the infec-ted group was obviously higher than that in the uninfected group(P＜0.05),but the expression level of ser-um miR-103a-3p in the infected group was obviously lower than that in the uninfected group(P＜0.05).The expression level of lncRNA FGD5-AS1 was an independent risk factor for PI in late-pregnancy GDM patients(P＜0.05),and the expression level of miR-103a-3p was an independent protective factor for PI in late-preg-nancy GDM patients(P＜0.05).There was a negative correlation between lncRNA FGD5-AS1 and miR-103a-3p expression level(r=-0.409,P＜0.001).The efficacy of the combined detection of lncRNA FGD5-AS1 and miR-103a-3p for predicting PI in late pregnancy GDM patients was superior to that of serum lncRNA FGD5-AS1 and miR-103a-3p alone(P＜0.05).Conclusion LncRNA FGD5-AS1 is an independent risk factor for PI in late pregnancy GDM patients,while miR-103a-3p is an independent protective factor for PI in late pregnancy GDM patients.The combined detection has higher value for predicting PI in late pregnancy GDM patients.

Objective:To analyze the monitoring data of Kashin-Beck disease (KBD) in Gansu Province and learn about the long-term trend of KBD incidence.Methods:The X-ray detection rate of children with KBD in Gansu Province from 1990 to 2021 was collected through Gansu Provincial Center for Disease Control and Prevention. Joinpoint regression model was used to analyze the trend of X-ray detection rate of KBD in children. The annual percent change (APC) and average annual percent change (AAPC) were used to analyze the trend of the observed indicators. In addition, a polynomial regression model was constructed to fit the change of X-ray detection rate of children with KBD over time.Results:From 1990 to 2021, a total of 126 726 children were examined for KBD by X-ray in Gansu Province, with 3 011 positive cases, X-ray detection rate of KBD in children was 0 in 2019 - 2021. Joinpoint regression model analysis showed that the X-ray detection rate of children with KBD in Gansu Province from 1990 to 2018 showed a decreasing trend (AAPC = - 14.40%, P = 0.001). The APC of 1990 - 1998, 2002 - 2008 and 2008 - 2012 was - 17.75%, - 21.89% and - 49.89%, respectively, showing a decreasing trend ( P < 0.05). The APC of 2012 - 2018 was 6.15%, but the trend change was not statistically significant ( P = 0.475). The curve fitting of X-ray detection rate of KBD in children in Gansu Province over time was carried out, and the quadric polynomial equation was y = 0.000 314 5 x4 - 0.021 37 x3 + 0.487 1 x2 - 4.635 x + 22.08. Conclusions:The condition of KBD in children of Gansu Province has been effectively controlled. The X-ray detection rate has remained at a relatively low level since 2012, and it has reached a state of elimination since 2019.

Gastroesophageal reflux disease （GERD） is a frequently and commonly occurring disease in clinic. In recent decades， with the development in pathophysiology and drug researches， modern medicine has achieved remarkable progress and results in diagnosis and treatment. However， the treatments for non-erosive reflux disease， refractory gastroesophageal reflux disease， proton pump inhibitor resistance， overlap of disease symptoms， and extraesophageal symptoms are limited and ineffective. Traditional Chinese medicine （TCM） was widely used in clinical practice， which has been proved effective in relieving symptoms and improving the quality of life. Sponsored by China Association of Chinese Medicine （CACM） and undertaken by the Spleen and Stomach Disease Branch of CACM， "the 12^th Youth Salon of Clinical Predominance Disease Series （GERD）" invited 18 authoritative digestive experts of TCM and western medicine to discuss "the difficulties of clinical diagnosis and treatment of GERD and TCM advantages". The focus issues such as modern medical diagnosis and treatment achievements and contributions， improvement and maintenance of symptoms， response to overlapping disease symptoms， reduction and withdrawal of acid suppressors， and treatment of extra-esophageal symptoms were discussed in depth. TCM and western medicine exchanged and complemented each other's strengths， combing the difficulties of modern medical diagnosis and treatment， which clarified the positioning and advantages of TCM and provided guidance for clinical and scientific research.

Objective:To observe the diagnostic value of six classification intelligent auxiliary diagnosis lightweight model for common fundus diseases based on fundus color photography.Methods:A applied research. A dataset of 2 400 color fundus images from Nanjing Medical University Eye Hospital and Zhejiang Mathematical Medical Society Smart Eye Database was collected, which was desensitized and labeled by a fundus specialist. Of these, 400 each were for diabetic retinopathy, glaucoma, retinal vein occlusion, high myopia, age-related macular degeneration, and normal fundus. The parameters obtained from the classical classification models VGGNet16, ResNet50, DenseNet121 and lightweight classification models MobileNet3, ShuffleNet2, GhostNet trained on the ImageNet dataset were migrated to the six-classified common fundus disease intelligent aid diagnostic model using a migration learning approach during training as initialization parameters for training to obtain the latest model. 1 315 color fundus images of clinical patients were used as the test set. Evaluation metrics included sensitivity, specificity, accuracy, F1-Score and agreement of diagnostic tests (Kappa value); comparison of subject working characteristic curves as well as area under the curve values for different models.Result:Compared with the classical classification model, the storage size and number of parameters of the three lightweight classification models were significantly reduced, with ShuffleNetV2 having an average recognition time per sheet 438.08 ms faster than the classical classification model VGGNet16. All 3 lightweight classification models had Accuracy > 80.0%; Kappa values > 70.0% with significant agreement; sensitivity, specificity, and F1-Score for the diagnosis of normal fundus images were ≥ 98.0%; Macro-F1 was 78.2%, 79.4%, and 81.5%, respectively.Conclusion:The intelligent assisted diagnosis of common fundus diseases based on fundus color photography is a lightweight model with high recognition accuracy and speed; the storage size and number of parameters are significantly reduced compared with the classical classification model.

Objective:To analyze the clinical manifestations and esophageal motility characteristics of patients with gastroesophageal reflux disease (GERD) and extra-esophageal symptoms.Methods:From January 1 to October 30, 2018, at PLA Rocket Force Characteristic Medical Center, 180 hospitalized patients diagnosed with GERD and extra-esophageal symptoms were retrospectively analyzed. The patients were divided into laryngopharyngeal symptom group (65 cases), airway symptom group (58 cases) and mixed symptom group (57 cases). General data, clinical symptoms, gastroscopic manitestations, the results of high-resolution esophageal manometry and 24-hour multichannel intraluminal impedance and pH monitoring of each group were analyzed and compared. Chi-square test and one-way analysis of variance were used for statistical analysis.Results:The patients aged <40, 40 to 60 and >60 years accounted for 12.8% (23/180), 53.3% (96/180) and 33.9% (61/180), respectively, and the difference was statistically significant ( χ2=12.030, P=0.017). There were 18.9%(34/180) of patients without typical reflux symptoms. There were statistically significant differences in the incidence of ectopic esophagogastric mucosa or Barrett esophagus under gastroscopy between laryngopharyngeal symptom group, airway symptom group and mixed symptom group (21.5%, 14/65; 5.2%, 3/58 and 8.8%, 5/57, respectively) ( χ2=8.578, P=0.014). There were no statistically significant differences in the lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure or distal contractile integral between laryngopharyngeal symptom group, airway symptom group and mixed symptom group ((8.57±0.76), (8.87±0.79), and (10.51±0.97) mmHg (1 mmHg=0.133 kPa); (44.75±2.86), (42.81±4.06), and (39.14±3.20) mmHg; (506.13±64.30), (432.59±78.10), and (682.99±82.28) mmHg·s·cm)(all P>0.05). The DeMeester score of laryngopharyngeal symptom group , mixed symptom group and airway symptom group was (14.33±2.09), (21.94±5.30) and (30.47±5.85) points, respectively, and the difference was statistically significant ( F=3.226, P=0.043). The results of multi-channel impedance monitoring showed that acid reflux and weak acid reflux were the main reflux in the patients, which accounted for 55.5% (76/137) and 34.3% (47/137), respectively. Among 87.6% (120/137) of the patients, reflux mainly occurred in the upright position while 12.4% (17/137) of the patients had reflux in the supine position. Conclusions:The extra-esophageal symptoms of GERD is associated with age. Ectopic esophagogastric mucosa or Barrett esophagus are more common in GERD patients with laryngopharyngeal symptoms. There are more acid exposure and pathologic acid reflux in GERD mainly with airway symptoms. Weak acid reflux at upright position plays an important role in the reflux mechanism of GERD with extra-esophageal symptoms.
