Purpose To investigate the prenatal ultrasound features and prognosis of fetal patent urachal.Materials and Methods The prenatal ultrasound characteristics of six cases with patent urachal diagnosed in Women and Children's Hospital of Chongqing Medical University from September 2018 to March 2023 were retrospectively analyzed,their pregnancy and postnatal conditions were followed up.Results In the first and second trimester of pregnancy,the prenatal ultrasonography of six fetuses showed that the epurachus was occluded.Among them,two cases were diagnosed as bladder diverticulum.The ultrasonography showed that the bladder was malformed,the top of the bladder was changed like a beak,and was connected to the umbilical cord entrance of the abdominal wall through an abnormal tube.Four cases were diagnosed as urachal fistula with allantoic cyst.Ultrasound showed that the cyst was at the root of the umbilical cord,and the cyst communicated with the bladder through an abnormal duct.The size of the cyst changed with the filling and emptying of the bladder.Color Doppler showed that the cysts were surrounded by the umbilical artery.None of the six fetuses were abnormal by chromosome examination.Among them,two fetuses with simple urachal fistula and allantoic cyst were born with good prognosis,and the remaining four fetuses were induced by other malformations.One of the six fetuses was female,and five fetuses were male.Conclusion Prenatal ultrasound of patent urachus has typical features and low correlation with chromosomal abnormalities.It is more common in males clinically and has a good prognosis without other structural abnormalities.

Objective:To investigate the correlation between insulin resistance surrogate indicators and early-stage kidney injury in type 2 diabetes mellitus(T2DM).Methods:A total of 918 T2DM patients hospitalized in the Endocrinology Department of Xinhua Hospital from January 2018 to December 2020 were selected, including 313 patients with early-stage kidney injury and 605 without. Differences in insulin resistance surrogate indicators, including triglyceride to high-density lipoprotein cholesterol ratio(TG/HDL-C), triglyceride glucose(TyG) index, and triglyceride glucose-body mass index(TyG-BMI), were compared between the two groups. Factors associated with early-stage kidney injury in T2DM were analyzed, and the impact of TG/HDL-C, TyG index, and TyG-BMI on early-stage kidney injury in T2DM were explored.Results:Compared with T2DM patients without early-stage kidney injury, those with early-stage kidney injury exhibited significantly elevated levels of TG/HDL-C, TyG index, and TyG-BMI( P< 0.001). TG/HDL-C, TyG index, TyG-BMI, age, duration of diabetes, systolic blood pressure, fasting insulin, and HbA 1C were identified as independent risk factors for early-stage kidney injury in T2DM. Compared to the Q1 quartile, the risk in the Q4 quartile was 3.168 times(95% CI 1.993-5.036) for TG/HDL-C, 2.714 times(95% CI 1.710-4.306) for TyG index, and 2.893 times(95% CI 1.820-5.598) for TyG-BMI. Conclusion:Insulin resistance surrogate indicators TG/HDL-C, TyG index, and TyG-BMI are significantly elevated in T2DM patients with early-stage kidney injury, serving as independent risk factors for early-stage renal impairment in T2DM.

Objective:To investigate the predictive value of myocardial perfusion-related parameters measured by echocardiography on the prognosis of patients with coronary artery disease at 90 d after percutaneous coronary intervention (PCI).Methods:Eighty-five patients with coronary artery disease who underwent PCI in Linping Branch of the Second Affiliated Hospital of Zhejiang University from October 2020 to October 2022 were selected retrospectively. Patients were divided into the occurrence myocardial perfusion injury group (40 cases) and the non-occurrence myocardial perfusion injury group (45 cases). The quantitative echocardiographic parameters of left ventricular end-diastolic internal diameter (LVEDD) and left ventricular end-systolic internal diameter (LVESD) were compared between the two groups, and the effects of LVEDD and LVESD on the risk of myocardial perfusion injury after PCI in patients with coronary artery disease were analyzed. Logistic regression was used to analyze the factors influencing the major adverse cardiovascular events (MACE) of patients with coronary artery disease at 90 d after PCI. A line graph model was constructed, the receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were constructed to verify the predictive efficiency of the line graph model.Results:Compared with the day of admission, the levels of LVEDD and LVESD were increased at 2 and 6 h after PCI, and showed an increasing trend at each time point ( P<0.05). The levels of LVEDD and LVESD at 2 and 6 h after PCI in the occurrence myocardial perfusion injury group were higher than those in the non-occurrence myocardial perfusion injury group: (45.56 ± 2.35) mm vs. (43.27 ± 2.12 ) mm, (47.87 ± 3.56) mm vs. (45.73 ± 2.98) mm; (33.49 ± 2.32) mm vs. (31.29 ± 2.29) mm, (35.62 ± 3.03) mm vs. (33.74 ± 2.12) mm, there were statistical differences ( P<0.05). The risk of myocardial perfusion injury was 4.469 and 6.081 times higher in patients with high levels of LVEDD and LVESD than in patients with low levels. The results of Logistic regression analysis showed that coronary multiple lesions, time from onset to balloon dilation, coronary Gensini score and LVEDD, LVESD were independent influencing factors of MACE at 90 d after PCI in patients with coronary artery disease ( P<0.05). Based on the above five independent influencing factors, a column line graph model was established to predict the risk of poor prognosis at 90 d after PCI. According to the column line graph model, the coronary multiple lesions were scored as 5; the corresponding prognostic adverse risk increased with the increase of time from onset to balloon dilation, coronary Gensini score and quantitative echocardiographic parameters LVEDD and LVESD; the internal validation of the column line graph prediction model was performed, and the C-index of the model was 0.978; the calibration curve showed that the model had good differentiation and accuracy in predicting the risk of MACE at 90 d after PCI. The results of ROC curve showed, the area under the curve (AUC) was 0.955 (95% CI 0.952 - 1.000). The DCA showed that when the line graph model was in the high risk threshold range (0 - 0.9), the prediction of the model had clinical practical value and the net benefit of patients was high. Conclusions:The abnormal increase of LVEDD and LVESD determined by echocardiography is associated with myocardial perfusion injury in patients with coronary heart disease after PCI, and a line graph model based on LVEDD and LVESD can predict the occurrence of MACE at 90 d after PCI, so as to guide early risk assessment and prevention.

Objective·To explore the correlation between serum small ubiquitin-like modifier 1(SUMO1)levels and hypertriglyceridemia in patients with type 2 diabetes mellitus(T2DM).Methods·A total of 239 newly diagnosed T2DM patients were recruited from the endocrinology clinic of Xinhua Hospital,Shanghai Jiao Tong University School of Medicine,between September 2020 and March 2021.Among them,92 patients had hypertriglyceridemia,and 147 patients did not.Basic information and laboratory parameters were collected.The differences in serum SUMO1 levels between the two groups were analyzed.Factors influencing hypertriglyceridemia in patients with T2DM were analyzed,and the impact of serum SUMO1 levels on the risk of hypertriglyceridemia in T2DM patients was investigated.Results·Patients with T2DM and hypertriglyceridemia had significantly higher serum SUMO1 levels compared to those without hypertriglyceridemia(1 114.99 pg/mL vs 902.43 pg/mL,P＜0.001).Binary Logistic regression analysis suggested that serum SUMO1 levels(OR=1.527,95%CI 1.200?1.943),glycated hemoglobin(OR=1.202,95%CI 1.038 ? 1.391),and blood uric acid(OR=1.006,95%CI 1.003 ? 1.010)were independent risk factors for hypertriglyceridemia in patients with T2DM.After adjusting for various confounding factors and stratifying serum SUMO1 levels into quartiles,the risk of hypertriglyceridemia in T2DM patients with the highest quartile(Q4)of serum SUMO1 levels was 2.707 times higher compared to those in the lowest quartile(Q1)(95%CI 1.231?5.951).Multiple linear stepwise regression analysis revealed that female gender,waist-to-hip ratio,triglycerides and serum creatinine were independent risk factors for elevated serum SUMO1 levels.Conclusion·Serum SUMO1 level in patients with T2DM complicated with HTG is significantly higher than that in patients without HTG,and the serum SUMO1 level is an independent risk factor for T2DM complicated with HTG.

Objective:To summarize the prenatal ultrasonographic features and prognosis of fetal umbilical-portal-systemic venous shunt (UPSVS).Methods:This retrospective study retrieved the records of 14 fetuses with UPSVS from Chongqing Health Center for Women and Children from January 2018 to September 2020, to describe their ultrasonographic features, concomitant malformations, chromosomal examination results, and follow-up.Results:All the 14 cases were classified into three types: Type Ⅰ ( n=2), the umbilical vein directly connected to the systemic venous detouring around the liver; Type Ⅱ ( n=2), the umbilical vein connected to the distal inferior vena cava instead of the left atrium after entering the liver through the ductus venosus; and Type Ⅲa ( n=10), those with an intrahepatic shunt, between the intrahepatic portal venous system and the hepatic vein. Of the 14 fetuses, 11 had normal chromosome test results, including four had serum screening of Down syndrome in the first trimester, four had non-invasive prenatal testing, and three had prenatal genetic diagnosis. Six cases were complicated by other system malformations. Fetal growth restriction and heart failure were found in four cases each. Four pregnancies were terminated due to other anomalies and the other 10 ended in live births with good prognosis for the fetuses. Conclusions:Special attention should be paid to the fetal umbilical- portal-venous system when there are unexplained fetal growth restriction, fetal heart failure, or abnormal blood vessels in the abdominal section of the fetus. UPSVS has typically ultrasonographic features, which can prenatally determine the shunt type and the integrity of the intrahepatic portal venous system. A full assessment of the intrauterine fetal condition and other malformations are of great value in prognostic counseling.

This paper reported a male newborn with Ebstein's anomaly complicated by type B Wolff-Parkinson-White syndrome. The baby was delivered at 39 weeks of gestation and diagnosed as Ebstein's anomaly complicated by type B Wolff-Parkinson-White syndrome 2 d after birth. He was improved and discharged after conservative management in the Department of Internal Medicine. No abnormality was found by fetal echocardiography at 20 weeks of gestation, while supraventricular tachycardia was diagnosed by M-mode ultrasonography at 38 weeks of gestation due to rapid fetal heart rate. In addition to hemodynamic changes,the abnormal cardiac structure in patients with Ebstein's anomaly may also lead to tachyarrhythmia. Therefore, in fetuses diagnosed with supraventricular tachycardia by prenatal ultrasound or children with type B Wolff-Parkinson-White syndrome detected by electrocardiogram after birth, tricuspid valve should be carefully scanned under echocardiography to avoid the missed diagnosis of Ebstein's anomaly.

Objective: To observe the effect of transforming growth factor-β1 (TGF-β1) on the migration of oral carcinoma associated fibroblasts (CAFs) with two-dimensional culture model and three-dimensional model. Methods : Under two-dimensional culture conditions, CAFs stimulated by TGF-β1 with the addition of 10 ng/mL medium were used as the experimental group, and untreated CAFs were used as the control group. The migration of CAFs with the stimulation of TGF-β1 was measured by cell scratch assay and transwell assay. CAFs positive for green fluorescent protein (GFP) were cultured by retrovirus transfection. Human tongue squamous cell carcinoma cells SCC25, GFP(+) CAFs and CAFs with three-dimensional cell co-culture models were established. The three-dimensional model cultured under the stimulation of TGF-β1 with 10 ng/mL medium was used as the experimental group, and the three-dimensional model without TGF-β1 was used as the control group. The migration of CAFs with the stimulation of TGF-β1 was also measured by the three-dimensional models. Results: It was verified that 10 ng/mL TGF-β1 promoted the migration of CAFs in the two-dimensional culture model. The three-dimensional co-culture models of SCC25, GFP(+) CAFs and CAFs were successfully established. The migration of SCC25 and CAFs was detected in the three-dimensional model. However, 10 ng/mL TGF-β1 had little effect on their migration. Conclusion The effect of TGF-β1 in vitro on the migration of oral CAFs was associated with different culture models in two and three dimensions.
