Objective To detect serum level of long noncoding RNA ( lncRNA) BC200 in gastric cancer(GC) patients, and investigate its relationship with clinical features , and evaluate its diagnostic value for GC.Methods A case-control study was performed.From November 2014 to July 2015, serum levels of lncRNA BC200 were detected by real-time quantitative polymerase chain reaction in 124 patients with GC , 41 patients with atrophic gastritis and 59 normal controls who were hospitalized in Qilu Hospital of Shandong University.Meanwhile , serum carcinoembryonic antigen ( CEA ) and carbohydrate antigen 72-4 ( CA72-4 ) were detected by electrochemical luminescence immunoassay .Serum levels of lncRNA BC200, before and 3, 7, 10, 30, 100 days after radical operation in another 31 patients with GC were determined.The sensitivity and specificity of serum lncRNA BC200, CEA and CA72-4 were analyzed by using of the receiver operating characteristic ( ROC) curve.The comparison between two groups was performed with Mann-Whitney U test and the comparison among many groups was conducted with Kruskal-Wallis H test.Results Serum levels of lncRNA BC200 in GC patients with stage Ⅰ and Ⅱ[1.041(0.794,1.462)] and stage Ⅲ and Ⅳ[1.290 (0.978,1.794)]were significantly higher than those in patients with precancerous lesion [0.969(0.699, 1.219)]and normal controls[0.801(0.556,1.599)](H =54.68,P<0.000 1).Compared with pre-operation[1.120 (0.859,1.663)], the serum BC200 levels decreased significantly in 10 days [0.903 (0.724,1.182)](U=55.0,P<0.000 1), 30 days[0.759(0.671,1.037)](U=299.0,P=0.026 1), and 100 days[0.478(0.378,0.635)](U=41.0,P<0.000 1) after surgery.The area under the receiver operating characteristics curve ( AUC) of serum lncRNA BC200 was 0.865 for GC diagnosis, which was significantly higher than that of serum CA 72-4 ( AUC =0.699 ) or CEA ( AUC =0.807 ) .The AUC of combined detection of three tests was 0.934.Conclusion Serum lncRNA BC200 levels are significantly increased in GC patients , which may be used as a potential biomarker in GC diagnosis and monitoring .

OBJECTIVETo analyze the clinical characteristics and diagnosis of 2 cases with chylothorax due to primary lymphatic dysplasia and to elevate pediatrician's recognition level for this disease.

METHODClinical manifestations of the children were retrospectively analyzed. Primary lymphatic dysplasia was diagnosed by lymphoscintigraphy.

RESULTThe first patient was a male aged 2-year-7-month who presented with a history of tachypnea for 43 days, fever and sore throat for 5 days at the early stage of the illness. He had a history of external injury before his illness. Physical examination showed his left chest bulging and left side diminished breath sound. His pleural effusion showed dark red (It was divided into two layers after standing, the upper layer turned into milky white, and the lower turned into hemorrhagic liquid) . White blood cell (WBC) count was 9 000×10(6)/L, mononuclear cell was 0.9, polykaryocytes was 0.1, triglyceride was 12.37 mmol/L in the pleural effusion. Contrast-enhanced lung CT (revascularization) showed pericardial effusion and a massive left sided pleural effusion. The second patient was a male aged 9 years and 6 months, who presented with a history of cough for 24 days, intermittent fever, vomiting, abdominal pain for 19 days, and edema of lower limbs for 4 days. Physical examination showed edema in both eyelids, lower extremities and scrotum. The level of albumin was 14 g/L and the titer of Mycoplasma pneumoniae IgM was 1: 320 in the serum. His hydrothorax pleural effusion showed milk white. White blood cell (WBC) count was 74×10(6)/L, mononuclear cell was 0.78, polykaryocytes was 0.22, triglyceride was 1.01 mmol/L in the pleural effusion. Chyle test showed positive in his pleural effusion and seroperitoneum. High-resolution CT of the lung revealed bilateral interstitial and parenchymal infiltration and both sided pleural effusion. Abdominal ultrasound showed giant hypertrophy of the gastric mucosa and massive ascites. Gastroscopy showed giant hypertrophy of the gastric mucosa. Lymphoscintigraphy revealed primary lymphatic dysplasia in both children.

CONCLUSIONPrimary lymphatic dysplasia might occur in children and result in dropsy of serous cavity (chylothorax, chylopericardium, chylous ascites). Dropsy of serous cavity showed bloody or milk white. WBC count might elevate with lymphocyte increasing mostly, triglyceride was often higher than 1.0 mmol/L in dropsy of serous cavity. Primary lymphatic dysplasia can be diagnosed by lymphoscintigraphy.

Objective:To evaluate the morphological characteristics of the fetal heart and the contractile function of the left and right ventricles in fetuses with pulmonary stenosis (PS) and pulmonary atresia (PA) using fetal heart quantitative analysis technology (fetal HQ), and to assess the impact of different degrees of right ventricular outflow tract obstruction (RVOTO) on the contractile function of the fetal left and right ventricles. To accumulate early data and explore parameters for constructing a predictive model and clinical decision-making tool for the progression of fetal PS and PA.Methods:A retrospective analysis was conducted on 42 cases of mild to moderate PS and 23 cases of severe PS or PA detected through fetal echocardiography in the Department of Ultrasound, Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, from July 2020 to December 2021. A control group of 195 normal fetal cases matching gestational weeks was selected. The fetal HQ technique was employed to measure the global sphericity index (GSI), left ventricular ejection fraction (EF), left/right ventricular area change percentage (LVFAC, RVFAC), and left/right ventricular longitudinal strain (LVGLS, RVGLS). Additionally, 24-segment sphericity index (SI) and fractional shortening (FS) for both left and right ventricles were measured. Comparative analyses were performed between the case and control groups, as well as within the case group.Results:In comparison with the control group, the case group exhibited significantly decreased GSI, LVGLS, LVEF, LVFAC, RVGLS, and RVFAC.The differences were statistically significant in the mild to moderate PS group (all P<0.05) and highly significant in the severe PS/PA group (all P<0.01). In the mild to moderate PS group, the left ventricle′s 2nd segment, right ventricle′s 24th segment SI, and the left ventricle′s 1st-13th segments, right ventricle′s 1st-16th and 20th-24th segments FS showed statistically significant differences compared to the control group (all P<0.05). In the severe PS/PA group, the right ventricle′s 1st-22nd segment SI, and the left ventricle′s 6th-13th, 21st-24th segments, and the right ventricle′s 1st-14th segments FS were reduced, showing statistically significant differences compared to the control group (all P<0.05). The severe PS/PA group showed lower RVGLS, RVFAC, and SI for the right ventricle′s 1st to 17th segments when compared to the mild to moderate PS group, with statistically significant differences (all P<0.05). Conclusions:Quantitative indices derived by fetal HQ is capable of evaluating the cardiac morphology and function of fetuses with PS/PA, which may provide for reference information for comprehensive understanding of cardiac morphological and functional changes in such fetuses.

Objective To investigate the association between lifestyle and risk of heart disease and diabetes in the elderly population in Xi'an City. Methods From January 2021 to January 2024, a staged cluster sampling method was used to investigate the lifestyle and the occurrence of heart disease and diabetes in elderly population aged 60 years and above in the communities of Xi'an. Multivariate logistic regression was used to analyze the relationship between lifestyle and the risk of heart disease and diabetes. Results A total of 413 elderly people were investigated, of which 31.96% had heart disease, 27.12% had diabetes, and 10.90% had diabetes with heart disease. Multivariate logistic regression analysis revealed that age, BMI, family history, sweet food preference, smoking, and sitting and lying for a long time were risk factors for diabetes in the elderly population (P<0.05). Age, BMI, family history, history of diabetes, preference for salted products, smoking, drinking, and sitting and lying for a long time were risk factors for heart disease in the elderly population (P<0.05). Conclusion The incidence rates of heart disease and diabetes are high in the elderly population in Xi'an City. The risk of diabetes is related to unhealthy lifestyles such as sweet food preference, smoking, and sitting and lying for a long time, while heart disease is related to unhealthy lifestyles such as preference for salted products, smoking, drinking, and sitting and lying for a long time.
