Objective To explore the value of the combination of serum hemoglobin A1c(HbA1c),Alarin and Ficolin-3 in predicting adverse pregnancy outcomes in patients with gestational diabetes mellitus(GDM).Methods From March 2021 to March 2023,129 GDM patients who underwent prenatal examination and hospital delivery in Yantai Yeda Hospital were collected as the GDM group,while 133 pregnant women with normal glucose tolerance test results were regarded as the control group.Fully automated glycated hemoglobin analyzer was applied to detect serum HbA1c level.Enzyme linked immunosorbent assay(ELISA)was applied to detect serum Alarin and Ficolin-3 levels.Pearson method was used to analyze the correlation between serum HbA1c,Alarin,Ficolin-3 levels and 2 hour postprandial glucose(2 h PG),fasting blood glucose(FBG)and homeostasis model assessment method for insulin resistance(HOMA-IR)in GDM patients.Logistic regression was applied to analyze the relationship between HbA1c,Alarin,Ficolin-3 levels and adverse pregnancy outcomes in GDM patients.Receiver operating characteristic(ROC)curve was plotted to analyze the value of serum HbA1c,Alarin and Ficolin-3 levels in predicting adverse pregnancy outcomes in GDM patients.Results The 2 h PG,FBG,HOMA-IR,and serum HbA1c,Alarin,and Ficolin-3 levels were significantly higher in the GDM group than those in the control group(P＜0.05).The serum levels of HbA1c,Alarin and Ficolin-3 were positively correlated with 2 h PG,FBG and HOMA-IR in GDM patients(P＜0.05).The serum HbA1c,Alarin and Ficolin-3 levels were greatly higher in GDM patients with poor blood glucose control than those in GDM patients with good blood glucose control(P＜0.05).The above levels of three indicators in GDM patients with adverse pregnancy outcomes were significantly higher than those in GDM patients without adverse pregnancy outcomes(P＜0.05).Elevated levels of HbA1c,Alarin and Ficolin-3 were independent risk factors for adverse pregnancy outcomes in GDM patients(P＜0.05).The area under the curves of HbA1c,Alarin and Ficolin-3 alone and in combination were 0.840,0.865,0.815 and 0.979,respectively in predicting adverse pregnancy outcomes in GDM patients.Conclusion The serum HbA1c,Alarin and Ficolin-3 levels are abnormally elevated in GDM patients,and the combined detection of the three can improve the value in predicting adverse pregnancy outcomes.

Objective:To study the treatment outcomes of transjugular intrahepatic portal shunt (TIPS) on refractory hepatic sinus obstruction syndrome (HSOS) caused by Gynura segetum.Methods:The clinical data of 15 patients with refractory HSOS caused by Gynura segetum treated at the Department of Vascular Surgery, Henan Provincial People's Hospital from January 2017 to April 2021 were retrospectively analyzed. There were 7 males and 8 females, with ages ranging from 30 to 85 years, mean ± s. d. (61.2±14.1) years. Albumin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, glutamyl transferase, and portal vein pressure were compared before and after TIPS. The liver function and renal function of these patients were followed up.Results:When compared with pre-operation, the albumin, alanine aminotransferase, aspartate aminotransferase and other indexes were significantly improved after TIPS (all P<0.05). The portal vein pressure of 15 patients significantly decreased from the preoperative volume of (41.7±3.5) cmH 2O (1 cmH 2O=0.098 kPa) to (28.3±4.4) cmH 2O ( t=10.41, P<0.001). The preoperative liver function was Child-Pugh grade A in 1 patient, grade B in 8 patients, grade C in 6 patients. The postoperative Child-Pugh grading was grade A in 14 patients and grade B in 1 patient. Ascites, gastrointestinal bleeding, abdominal pain, abdominal distention and spontaneous peritonitis all disappeared in these 15 patients. Postoperative hepatic encephalopathy developed in 2 patients and hepatic myelopathy in 1 patient. Conclusion:TIPS for treatment of HSOS caused by Gynura segetum resulted in a rapid recovery of liver function, rapid symptomatic relief, with a low incidence of hepatic encephalopathy/hepatic myelopathy.

Objective:To evaluate multi-channel transcatheter embolotherapy for type Ⅱ endoleak originating from lumbar arteries after endovascular abdominal aortic aneurysm repair (EVAR).Methods:Data of 8 cases of type Ⅱ endoleak after EVAR from Oct 2017 to Nov 2020 at the Department of Vascular and Endovascular Surgery, Henan Provincial People's Hospital were retrospectively analyzed.Results:All patients who suffered from type Ⅱ endoleak that originated from lumbar arteries after EVAR were successfully treated with coils and mixture of Compant medical glue and iodipin through multi-channel. The technical success rate was 100%, the operative time was 80-150 min. Right lower limb dyskinesia occurred in 1 patient after operation, the symptom disappeared by anticoagulation and trophic neurotherapy for 2 months. Type Ⅱ endoleak didn't recur in all patients, and no mortality during the 4-38(14.1) months follow-up period.Conclusion:Multi-channel transcatheter embolotherapy has definite effects for the treatment of type Ⅱ endoleak from lumbar arteries after EVAR, with high technical feasibility, few perioperative complications, low mortality among other advantages. The results of short and medium term are satisfactory.

Objective:To explore the effect of tumor deposit (TD) on the prognosis of patients with stage Ⅲ colon cancer after radical resection.Methods:The clinicopathological data of patients with stage Ⅲ colon cancer after radical surgery at the Department of Gastrointestinal Surgery, Peking University People's Hospital from Jan to Dec 2015 were analyzed collected. Clinicopathological characteristics such as tumor location, degree of differentiation, mismatch repair status, lymphatic and venous invasion, and preoperative CEA and CA19-9 levels were used to study the effect of TD on the postoperative survival of patients.Results:Among the 155 patients with stage Ⅲ colon cancer, 37 (23.9%) had tumor deposits. The incidence of tumor deposits was higher in patients with intravascular tumor thrombus and preoperative serum CA19-9 elevation ( χ2=9.567, P=0.002; χ2=11.561, P=0.003); Patients with tumor deposits had worse overall survival and disease-free survival than those without cancer nodules (OS: P=0.029, DFS: P=0.025). Multivariate COX analysis found that tumor deposit was an independent risk factor for postoperative overall survival and disease-free survival ( HR=1.990, 95% CI: 1.032-3.835, P=0.040; HR=2.416, 95% CI : 1.205-3.820, P=0.009). Conclusions:Tumor deposit is an independent risk factor affecting postoperative overall survival and disease-free survival in patients with stage Ⅲ colon cancer. For patients with lymph node metastasis, incorporating TD into TNM staging can more accurately predict the postoperative prognosis.

Objective:To observe the clinical characteristics of esophageal reflux after total gastrectomy (ERATG), and to explore the mechanism of occurrence.Methods:Fourteen gastric cancer patients who underwent total gastrectomy were prospectively enrolled in this study. The postoperative symptoms were observed and recorded and 24 h MII-pH with pH monitoring was performed to investigate the characteristics of postoperative reflux.Results:After total gastrectomy patients were with different degrees of ERATG as heartburn, appetite loss, chest tightness and belching. The overall nature of ERATG is mainly weak acid, with a pH between 4 and 7. ERATG involved esophageal-jejunal anastomosis and a length of esophagus 7 cm above the anastomosis. Patients with typical reflux symptoms had a lower pH minimum in the upright position than those without typical symptoms[(4.76±0.71) vs.(5.68±0.37), t=2.866, P<0.05]. Patients with typical reflux symptoms had a higher frequency of reflux of mixed liquid and liquid-air reflux than those without typical symptoms[liquid(31.25±29.76) vs.(4.50±9.14), t=0.011, P<0.05; liquid-air(19.50±12.99) vs.(2.00±2.61), t=0.004, P<0.05]. Conclusion:ERATG is mainly a upward reflux of weakly acidic gas, with typical symptoms of heartburn, appetite loss, chest tightness and belching. Patients with typical symptoms usually have lower pH in the upright position.

Objective To investigate the feasibility of absorbable magnesium alloy screws in atlantoaxial dislocation fixation. Methods Four kinds of screws with triangular, rectangular, trapezoidal and zigzag thread were designed with WE43 magnesium alloy. The finite element simulation analyses were performed on the screw- polyurethane model and atlantoaxial fixation system model. The stress and displacement distributions on the models were obtained. Results The pull-out force simulations were carried out on four kinds of magnesium alloy screws according to ASTM F543 standard specification. The stresses of screws with triangular, rectangular, trapezoidal and zigzag thread were 146.20, 185.22,194.98, 264.55 MPa, respectively. The pull-out strength of the screw with triangular thread was the largest, and the peak stress was the smallest. The magnesium alloy screw with triangular thread used for atlantoaxial fixation could meet the strength requirements of flexion/extension, rotation and bending of the neck. The peak stress of the screw was reduced by 17.16 MPa after adding hydroxyapatite (HA) coating on the surface, and the stress on the screw was within the range of bonding strength between coating and magnesium alloy substrate. Conclusions Under the same loading condition, the screw with triangular thread has good stability and the best pull-out force performance. After heat treatment, the strength of magnesium alloy screw with triangular thread meets the load-bearing requirements for atlantoaxial dislocation fixation. HA coating on screw surface can optimize mechanical properties of the screw, and there exits good bonding strength between the coating and the screw.

Objective:To evaluate the short- and medium-term clinical efficacy of TIPS approach combined with AngioJet thrombus aspiration technology treatment in acute portal vein thrombosis.Methods:63 cases with acute portal vein thrombosis treated in our center from May 2017 to July 2019 were studied retrospectively, including 49 males and 14 females, aged 35-61 (46 ± 5) years. TIPS approach (with/without) combined with Angiojet thrombus aspiration and gastroesophageal varices embolization was performed simultaneously according to the patient's condition. Regular follow-up for 3-33 (22 ± 3) months after surgery was used to observe the curative effect.Results:The technical success rate was 100%. Portal vein and superior mesenteric vein blood flow were returned to normal after the operation. Two cases of biliary tract injury were untreated. Simultaneously, two cases of intrahepatic arteriovenous fistula were treated with superselective arterial embolization. During the follow-up period, 47 cases (74.61%) had complete portal vein recanalization, 13 cases (20.63%) had partial recanalization, 3 cases (4.76%) had complete portal cavernoma, 7 cases (11.11%) had symptomatic hepatic encephalopathy, 1 case had received artificial liver treatment (1.59%), 1 case had peptic ulcer (11.11%), 6 cases (9.52%) had lost to follow-up, and there was no portal hypertension-related bleeding or death.Conclusion:TIPS approach combined with AngioJet thrombus aspiration technology is safe, effective and feasible in the treatment of acute portal vein thrombosis, and the short- and medium-term clinical effects are satisfactory.

Objective:To investigate the safety and efficacy of AngioJet rheolytic thrombectomy (ART) treatment in patients with acute pulmonary embolism (APE).Methods:The clinical data of 21 consecutive APE patients with failed fibrinolytic therapy or fibrinolytic therapy contraindications were reviewed retrospectively, from January 2017 to October 2018 in Henan Provincial people's Hospital. Patients were classified into massive pulmonary embolism (MPE, 10 cases) and sub-massive pulmonary embolism (sMPE, 11 cases) according to the clinical presentation and CT angiography (CTA) results. All the patients were treated with emergency ART. The technical success rate and procedural success rate were calculated based on the angiography results and the occurrence of serious adverse events. The pre- and postoperative parameters including shock index (SI), Miller index (MI), mean pulmonary artery pressure (MPAP) and partial pressure of arterial oxygen (PaO 2) were compared using independent sample t test or Wilcoxon signed ranks test. Results:The technical success rate was 100% (21/21), and the procedural success rate was 71.4%(15/21) with 4 patients presenting severe arrhythmia, 1 patient with intraoperative severe dyspnea and 1 patient with intracranial hemorrhage. Both MPE and sMPE patients showed improvement of clinical symptoms after operation. It showed that the postoperative SI, MI and MPAP values decreased and PaO 2 increased compared with the preoperative values, with significant differences found (all P<0.05). All patients were discharged from hospital, except 1 patients left hospital due to serious illness. The mean follow-up period was (5.3±1.2) months, and 2 MPE patients expired due to cancer and acute myocardial infarction. All survivors didn't show recurrent APE symptoms and follow-up CTA showed no signs of embolism in pulmonary artery. Conclusion:ART can be used safely and effectively in APE patients, and can be prosposed as a new strategy in treatment of APE.
