Research progress on the influence of iodine nutritional status on biomarkers of thyroid cancer / 中华地方病学杂志

Thyroid cancer is one of the common malignant tumors in the endocrine system, and its incidence is increasing year by year. At present, the main diagnostic methods for thyroid cancer are ultrasound and thyroid puncture cytology. However, due to low sensitivity and/or specificity, it is increasingly difficult to meet the current clinical diagnostic needs. The discovery of biomarkers in thyroid cancer provides important clues for the diagnosis, pathogenesis and prognosis of the disease. As one of the essential trace elements in human body, iodine is closely related to the thyroid gland. Clarifying the relationship between iodine nutritional status and biomarkers of thyroid cancer has important practical significance for the diagnosis, pathogenesis and prognosis of thyroid cancer. Based on the research of systems biology, this article analyzes the influence of iodine nutritional status on biomarkers of thyroid cancer from four aspects of gene, transcription, protein and metabolism,

Clinical features of hypopituitarism with nonalcoholic fatty liver disease after sellar tumor surgery in children / 临床肝胆病杂志

Objective To investigate the clinical features of hypopituitarism with nonalcoholic fatty liver disease (NAFLD) in children after sellar tumor surgery and the association between hypopitarism and NAFLD in children. Methods A retrospective analysis was performed for the clinical data of children with hypopituitarism and NAFLD after sellar tumor surgery who were followed up regularly in Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2017 to December 2021, and their clinical features were analyzed. Results There were 32 children with regular follow-up and complete clinical data after sellar tumor surgery, and 10 children (31.25%) developed NAFLD, among whom there were 5 boys and 5 girls. Among these 10 children, 9 had craniopharyngioma and underwent surgical treatment, and 1 had germinoma and underwent local radiotherapy. The 10 children had a median age of 8.4(6.29.8) years at the diagnosis of hypopituitarism and a median age of 11.9(8.7-12.6) years at the diagnosis of NAFLD. The median number of years from the diagnosis of hypopituitarism to the diagnosis of NAFLD was 2.0(1.4-4.0) years. At the diagnosis of NAFLD, all 10 children had obesity, and body mass index (BMI) was increased by 7.26±4.25 kg/m 2 on average since the diagnosis of hypopituitarism; the 10 children had a mean fasting blood glucose level of 4.67±0.55 mmol/L, a mean fasting insulin level of 25.40±5.93 μIU/ml, and a mean HOMA-IR index of 5.26±1.29. Among these 10 children, 9 had hypertriglyceridemia, and 1 had elevated triglyceride, with a mean level of 3.08±1.09 mmol/L; 6 children had hypercholesterolemia, with a mean level of 5.67±1.25 mmol/L; 8 children had high-density lipoprotein cholesterolemia, with a mean level of 3.97±1.27 mmol/L. After the diagnosis of NAFLD, 2 children were treated with recombinant human growth hormone and metformin and achieved reductions in BMI, HOMA-IR, and triglyceride after treatment, and total cholesterol and low-density lipoprotein cholesterol were reduced to the normal range. Conclusion Children may experience weight gain, hypopituitarism, insulin resistance, and dyslipidemia after sellar tumor surgery, which may lead to the onset of NAFLD. Weight management and active pituitary hormone replacement therapy are recommended for such children, as well as routine screening and management of fatty liver disease.

Natural Medicinal Components Mediating Pyroptosis by GSDMs in Anti-tumor Therapy： A Review / 中国实验方剂学杂志

Pyroptosis， an atypical new cell death mode other than apoptosis and necrosis， has been discovered in recent years. Pyroptosis depends on the cleavage of gasdermins （GSDMs） by Caspases. The activated GSDMs act on the plasma membrane to form a perforation， which results in cell lysis and triggers inflammation and immune response. Pyroptosis can be induced by four distinct signaling pathways， including canonical and non-canonical inflammasome pathways， apoptosis-associated Caspases-mediated pathway， and granzyme pathway. In these signaling pathways， GSDMs are the executors of pyroptosis. Pyroptosis is associated with the death of tumor cells and the inflammatory damage of normal tissues. Recent studies have demonstrated that moderate pyroptosis can lead to tumor cell death to exert an anti-tumor effect， and meanwhile stimulate the tumor immune microenvironment， while it can promote tumor development. Despite the good performance， drug-based anti-tumor therapies such as tumor immunotherapy， chemotherapy， and targeted therapy have some shortcomings such as drug resistance， recurrence， and damage to normal tissues. The latest research shows that a variety of natural compounds have anti-tumor effects in the auxiliary treatment of tumors by mediating the pyroptosis pathways in a multi-target and multi-pathway manner， which provide new ideas for the study of anti-tumor therapy. We reviewed the molecular mechanism of pyroptosis and the regulatory role of pyroptosis in tumors and tumor immune microenvironment， and summarized the recent research progress in the natural medicinal components regulating pyroptosis in anti-tumor therapy， with a view to providing ideas for the research on the anti-tumor therapy based on pyroptosis.

OBJECTIVE@#To evaluate the clinical efficacy and adverse reactions of peginterferon-α2b for treatment of chronic myeloproliferative neoplasms (MPN).@*METHODS@#We retrospectively analyzed the data of 107 patients with MPN, including 95 with essential thrombocythemia (ET) and 12 with polycythemia vera (PV), who all received peginterferon-α2b treatment for at least 12 months. The clnical and follow-up data of the patients were analyzed to evaluate the efficacy and adverse reactions of the treatment.@*RESULTS@#After receiving peginterferon- α2b treatment, both ET and PV patients achieved high hematological remission rates, and the total remission rates did not differ significantly between the two groups (86% vs 78%, P>0.05). In the overall patients, the spleen index decreased by 13.5% (95%CI: 8.5%-18.5%) after the treatment. The patients with hematological remission showed a significantly greater reduction of the total symptom score than those without hematological remission (P < 0.01). The median percentage of JAK2V617F allele load of PV patients decreased from 67.23% (49.6%-84.86%) at baseline to 19.7% (0.57%-74.6%) after the treatment, and that of JAK2V617F-positive ET patients decreased from 48.97% (0.45%-74.24%) at baseline to 22.1% (0.33%-65.42%) after the treatment. Mild adverse reactions (grade 1-2) were observed in both ET and PV groups without significant differences between them. The overall incidence of thrombotic events during the treatment was 2.8% in these patients, and no serious adverse reactions were observed.@*CONCLUSION@#For patients with chronic myelodysplasia, peginterferon-α2b treatment can achieve a high peripheral blood cell remission rate and maintain a long-term stable state with good effect in relieving symptoms such as splenomegaly. Peginterferon- α2b treatment caused only mild adverse reactions, which can be tolerated by most of the patients.

Objective: We aimed to explore the feasibility of a single-port thoracoscopy- assisted five-step laparoscopic procedure via transabdominal diaphragmatic(TD) approach(abbreviated as five-step maneuver) for No.111 lymphadenectomy in patients with Siewert type II esophageal gastric junction adenocarcinoma (AEG). Methods: This was a descriptive case series study. The inclusion criteria were as follows: (1) age 18-80 years; (2) diagnosis of Siewert type II AEG; (3) clinical tumor stage cT2-4aNanyM0; (4) meeting indications of the transthoracic single-port assisted laparoscopic five-step procedure incorporating lower mediastinal lymph node dissection via a TD approach; (5) Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1; and (6) American Society of Anesthesiologists classification I, II, or III. The exclusion criteria included previous esophageal or gastric surgery, other cancers within the previous 5 years, pregnancy or lactation, and serious medical conditions. We retrospectively collected and analyzed the clinical data of 17 patients (age [mean ± SD], [63.6±11.9] years; and 12 men) who met the inclusion criteria in the Guangdong Provincial Hospital of Chinese Medicine from January 2022 to September 2022. No.111 lymphadenectomy was performed using five-step maneuver as follows: superior to the diaphragm, starting caudad to the pericardium, along the direction of the cardio-phrenic angle and ending at the upper part of the cardio-phrenic angle, right to the right pleura and left to the fibrous pericardium , completely exposing the cardio-phrenic angle. The primary outcome includes the numbers of harvested and of positive No.111 lymph nodes. Results: Seventeen patients (3 proximal gastrectomy and 14 total gastrectomy) had undergone the five-step maneuver including lower mediastinal lymphadenectomy without conversion to laparotomy or thoracotomy and all had achieved R0 resection with no perioperative deaths. The total operative time was (268.2±32.9) minutes, and the lower mediastinal lymph node dissection time was (34.0±6.0) minutes. The median estimated blood loss was 50 (20-350) ml. A median of 7 (2-17) mediastinal lymph nodes and 2(0-6) No. 111 lymph nodes were harvested. No. 111 lymph node metastasis was identified in 1 patient. The time to first flatus occurred 3 (2-4) days postoperatively and thoracic drainage was used for 7 (4-15) days. The median postoperative hospital stay was 9 (6-16) days. One patient had a chylous fistula that resolved with conservative treatment. No serious complications occurred in any patient. Conclusion: The single-port thoracoscopy-assisted five-step laparoscopic procedure via a TD approach can facilitate No. 111 lymphadenectomy with few complications.

Development and Validation of a Nomogram Prediction Model for Endometrial Malignancy in Patients with Abnormal Uterine Bleeding

Purpose@#This study aimed to identify the risk factors and sonographic variables that could be integrated into a predictive model for endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) in women with abnormal uterine bleeding (AUB). @*Materials and Methods@#This retrospective study included 1837 patients who presented with AUB and underwent endometrial sampling. Multivariable logistic regression was developed based on clinical and sonographic covariates [endometrial thickness (ET), resistance index (RI) of the endometrial vasculature] assessed for their association with EC/AEH in the development group (n=1369), and a predictive nomogram was proposed. The model was validated in 468 patients. @*Results@#Histological examination revealed 167 patients (12.2%) with EC or AEH in the development group. Using multivariable logistic regression, the following variables were incorporated in the prediction of endometrial malignancy: metabolic diseases [odds ratio (OR)=7.764, 95% confidence intervals (CI) 5.042–11.955], family history (OR=3.555, 95% CI 1.055–11.971), age ≥40 years (OR=3.195, 95% CI 1.878–5.435), RI ≤0.5 (OR=8.733, 95% CI 4.311–17.692), and ET ≥10 mm (OR=8.479, 95% CI 5.440–13.216). :A nomogram was created using these five variables with an area under the curve of 0.837 (95% CI 0.800–0.874). The calibration curve showed good agreement between the observed and predicted occurrences. For the validation group, the model provided acceptable discrimination and calibration. @*Conclusion@#The proposed nomogram model showed moderate prediction accuracy in the differentiation between benign and malignant endometrial lesions among women with AUB.

It is a kind of operation method that can be popularized.

Anti-glioma mechanism of pterostilbene by regulating apoptosis and GSDME-mediated pyroptosis pathways: a study based on network pharmacology and experimental research / 中国中药杂志

This study aimed to explore the anti-glioma effect of natural compound pterostilbene(PTE) through regulating pyroptosis and apoptosis pathways, and to analyze the possible anti-glioma pathways and targets of PTE by network pharmacology and molecular docking. In this study, the action targets of PTE and the glioma targets were obtained by network pharmacology to construct a target network and a protein-protein interaction(PPI) network to predict the possible action targets of PTE against glioma. Molecular docking was performed on the core targets by AutoDock and the action pathways of PTE against glioma were predicted by enrichment analysis. In addition, the effect of PTE on the viability of U87MG and GL261 glioma cells was detected by CCK-8 assay. Clone formation assay and cell scratching assay were used to explore the effect of different concentrations of PTE on the proliferation and migration, respectively of glioma cells. Hoechst staining was used to observe PTE-induced apoptosis in glioma cells. The changes in mitochondrial membrane potential were detected by JC-1 staining. The pyroptosis-inducing effect of PTE on glioma cells was observed by inverted microscopy and lactate dehydrogenase(LDH) assay. Hoechst 33342/PI dual staining assay was performed to detect the integrity of glioma cell membranes. The expressions of pyroptosis and apoptosis-related proteins in glioma cells after PTE induction were determined by Western blot. In this study, 37 anti-glioma targets of PTE were obtained, and enrichment analysis suggested that PTE exerted anti-glioma effects through various signaling pathways including cancer pathway, proteoglycan in cancer, PI3K/AKT pathway, and apoptosis regulatory pathway. Molecular docking revealed that PTE had good binding activity with the main targets. Compared with the control group, PTE significantly reduced the viability as well as the proliferation, migration and adhesion abilities of U87MG and GL261 cells; it induced the apoptosis of the two glioma cells and the decrease of mitochondrial membrane potential in U87MG cells, and the effects increased with the increase of drug concentration. Compared with the conditions in the control group, glioma cells in the PTE group had increased pyroptosis-specific appearance and gradually increased LDH release; the number of PI positive cells was significantly elevated with the increase of PTE concentration as revealed by Hoechst 33342/PI staining; the expression levels of apoptosis-related factors cleaved PARP1 and B-cell lymphoma-2(Bcl-2) associated X(BAX) in the PTE group were markedly up-regulated, while the expression level of Bcl-2 was markedly down-regulated; the activation levels of pyroptosis-related proteins cleaved caspase-3 and gasdermin E-N(GSDME-N) had a remarkable rise in the PTE group, while no significant changes were found in the activation levels of gasdermin D-N(GSDMD-N) and cleaved caspase-1. In summary, PTE plays an anti-glioma role by inhibiting cell viability, proliferation, and migration and activating the caspase-3/GSDME-mediated pyroptosis pathway and mitochondrial apoptosis pathway.

Effect of Oleanolic Acid on Abnormal Water Metabolism of Mice with Water-dampness Retention Caused by Spleen Deficiency / 中国实验方剂学杂志

ObjectiveTo explore the effect of oleanolic acid （OA） on water metabolism in mice with water-dampness retention caused by spleen deficiency and the mechanism. MethodThe 60 SPF Kunming （KM） mice were randomized into blank group （n=10） and modeling group （n=50）. Through long-term living in damp place and irregular diet， water-dampness retention caused by spleen deficiency was induced in modeling mice. Then the model mice were randomly classified into model group， natural recovery group， and low-dose， medium-dose， and high-dose OA groups. The mice in the blank group， model group， and natural recovery group were given （ig） 10 mL·kg-1·d-1 normal saline， and mice in the low-dose， medium-dose， and high-dose OA groups received 50， 100， 200 mg·kg-1·d-1 OA， respectively. The intervention lasted 7 days. Before and after modeling and administration， the general conditions of the mice were observed and body weight of mice was measured. The water content in feces and tissues was detected with the oven-drying method， and water load index and organ coefficient were measured with the weighing method. Enzyme-linked immunosorbent assay （ELISA） was employed to detect the urinary D-xylose excretion， serum gastrin （GAS）， total protein （TP）， albumin （ALB）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， interleukin-6 （IL-6）， antidiuretic hormone （AVP）， aquaporin 1 （AQP1） in renal medulla， and liver Na+-K+-ATPase. At the same time， OA was docked with ALB， IL-6， AQP1， and Na+-K+-ATPase. ResultCompared with the blank group， the model group showed withered hair， emaciation， laziness， bradykinesia， slow weight growth， infrequent spontaneous activities， high water content in feces and tissues， low weight loss after water loading， high coefficient of each organ （P<0.05， P<0.01）. Moreover， the model group had less urinary D-xylose excretion， lower serum levels of GAS， TP， ALB， and HDL-C， higher levels of TC， LDL-C， AVP， and IL-6， lower expression of Na+-K+-ATPase in the liver， and higher expression of AQP1 in renal medulla than the blank group （P<0.05， P<0.01）. The three OA groups demonstrated better general conditions， faster weight gain， more frequent spontaneous activities， lower water content in feces and tissues， larger weight loss after water loading， and lower coefficient of each organ than the model group （P<0.05， P<0.01）. Moreover， compared with the model group， the three OA groups had high D-xylose excretion， high serum levels of GAS， TP， ALB， and HDL-C， low serum levels of TC， LDL-C， AVP， and IL-6， high expression of Na+-K+-ATPase in liver， and low expression of AQP1 in renal medulla （P<0.05， P<0.01）. The recovery in each OA group was better than that in natural recovery group. Molecular docking results also confirmed that OA had high binding affinity with ALB， IL-6， AQP1， and Na+-K+-ATPase. ConclusionOA can alleviate the abnormal water metabolism in mice with water-dampness retention caused by spleen deficiency， which lays a basis for its potential clinical application.

Relationship between MCU-mediated mitochondrial dynamics and intestinal ischemia-reperfusion injury in mice / 中华麻醉学杂志

Objective:To evaluate the relationship between mitochondrial calcium uniporter protein (MCU)-mediated mitochondrial dynamics and intestinal ischemia-reperfusion (I/R) injury in mice.Methods:Twenty-four wild-type adult male C57BL/6J mice, aged 6-8 weeks, weighing 18-20 g, were divided into 4 groups ( n=6 each) using a random number table method: sham operation group (S group), intestinal I/R group (IIR group), sham operation+ MCU inhibitor Ru360 group (S+ Ru360 group) and intestinal I/R + Ru360 group (IIR+ Ru360 group). The mouse model of intestinal I/R injury was prepared by clamping the root of the superior mesenteric artery for 45 min followed by 2 h of reperfusion in anesthetized animals. Small intestinal tissues were obtained at the end of reperfusion for examination of the intestinal mucosal injury which was scored according to Chiu and for determination of the content of malondialdehyde (MDA) (TBA method), activity of superoxide dismutase (SOD) (WST-8 method), content of lactic dehydrogenase (LDH) (colorimetric method), and expression of MCU, dynamin-related protein 1 (Drp1), recombinant human mitochondrial fission 1 protein (Fis1), mitofusin-1 (Mfn1) and Mfn2 (by Western blot). Results:Compared with S and S+ Ru360 groups, the Chiu′s score and contents of MDA and LDH were significantly increased, the activity of SOD was decreased, the expression of MCU, Drp1 and Fis1 was up-regulated, and the expression of Mfn1 and Mfn2 was down-regulated in IIR and IIR+ Ru360 groups ( P<0.05). Compared with IIR group, the Chiu′s score and contents of MDA and LDH were significantly decreased, the activity of SOD was increased, the expression of MCU, Drp1 and Fis1 was down-regulated, and the expression of Mfn1 and Mfn2 was up-regulated in IIR+ Ru360 group ( P<0.05). Conclusions:The mechanism underlying intestinal I/R injury may be related to MCU-induced promotion of mitochondrial fission, reduction of mitochondrial fusion and mediation of imbalance in mitochondrial dynamics in mice.

Detect and compare serum triglyceride(TG), total cholesterol(TC), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), fasting blood glucose(FBG)and the level of glycosylated hemoglobin A1c(HbA1c); The expression level of LncRNA HIF1A-AS1 in serum was detected by real-time fluorescence quantitative PCR(qRT-PCR)method; Logistic regression was used to analyze the risk factors that affected the occurrence of PDR; Receiver operating characteristic curve(ROC)was used to analyze the clinical value of LncRNA HIF1A-AS1 level in the diagnosis of PDR. RESULTS: The expression level of LncRNA HIF1A-AS1 in the serum of the patients in the PDR group was significantly higher than that in the NPDR group and the control group, and the NPDR group was higher than the control group(P&#x003C;0.05); The course of disease, HbA1c, TC, TG, LDL-C, FBG levels in the PDR group and the NPDR group were significantly higher than those of the control group, the HDL-C level in the PDR group was significantly lower than that in the control group(P&#x003C;0.05); The level of LncRNA HIF1A-AS1 was positively correlated with the course of disease, HbA1c, TC, TG, LDL-C and FBG(P&#x003C;0.05), and negatively correlated with HDL-C(P&#x003C;0.05); Logistic regression analysis showed that the LncRNA HIF1A-AS1, course of disease, FBG, HbA1c, TC, TG, LDL-C were all risk factors for PDR(P&#x003C;0.05); ROC results showed that the area under the curve(AUC)of the LncRNA HIF1A-AS1 level predicting PDR was 0.766(95%CI: 0.692～0.829), the corresponding sensitivity was 66.25% and the specificity was 78.75%.CONCLUSION: The level of LncRNA HIF1A-AS1 in the serum of PDR patients is up-regulated, it is a risk factor for the occurrence of PDR and it can be used as a potential serological indicator for predicting the occurrence of PDR.

The SACT Template: A Human Brain Diffusion Tensor Template for School-age Children / 神经科学通报·英文版

School-age children are in a specific development stage corresponding to juvenility, when the white matter of the brain experiences ongoing maturation. Diffusion-weighted magnetic resonance imaging (DWI), especially diffusion tensor imaging (DTI), is extensively used to characterize the maturation by assessing white matter properties in vivo. In the analysis of DWI data, spatial normalization is crucial for conducting inter-subject analyses or linking the individual space with the reference space. Using tensor-based registration with an appropriate diffusion tensor template presents high accuracy regarding spatial normalization. However, there is a lack of a standardized diffusion tensor template dedicated to school-age children with ongoing brain development. Here, we established the school-age children diffusion tensor (SACT) template by optimizing tensor reorientation on high-quality DTI data from a large sample of cognitively normal participants aged 6-12 years. With an age-balanced design, the SACT template represented the entire age range well by showing high similarity to the age-specific templates. Compared with the tensor template of adults, the SACT template revealed significantly higher spatial normalization accuracy and inter-subject coherence upon evaluation of subjects in two different datasets of school-age children. A practical application regarding the age associations with the normalized DTI-derived data was conducted to further compare the SACT template and the adult template. Although similar spatial patterns were found, the SACT template showed significant effects on the distributions of the statistical results, which may be related to the performance of spatial normalization. Looking forward, the SACT template could contribute to future studies of white matter development in both healthy and clinical populations. The SACT template is publicly available now ( https://figshare.com/articles/dataset/SACT_template/14071283 ).

Upregulation of h-TERT and Ki-67 in ectopic endometrium is associated with recurrence of endometriosis / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

At present, endometriosis remains a worldwide health burden, with the main symptoms of dysmenorrhea, chronic pelvic pain, and infertility, markedly reducing the quality of life (de Ziegler et al., 2010). Although there is no proof that the disease is associated with high mortality, this disorder can significantly contribute to the deterioration of women's general well-being (McPeak et al., 2018). The main current treatment for endometriosis is surgery to remove endometriotic lesions; however, the recurrence rate following surgical treatment is as high as 21.5% at two years and 40.0%‍-‍50.0% at five years post-surgery (Koga et al., 2015). To prevent recurrence, adjuvant treatment with drugs after surgery is recommended to prolong relapse-free intervals. However, it is inconvenient for patients to continuously use such medications in terms of adverse effects and cost (Turk, 2002).

Clinicopathological analysis of lung transplantation in the treatment of end-stage lung disease complicated with neuroendocrine carcinoma / 中华器官移植杂志

Objective:To explore the clinicopathological features of end-stage lung disease complicated with neuroendocrine carcinoma after lung transplantation (LT).Methods:From April 2017 to December 2021, 5 cases of neuroendocrine cancer were diagnosed as end-stage lung disease by hematoxylin-eosin (HE) and immunohistochemical stain.Clinical follow-up data, histological characteristics and immunophenotyping were analyzed retrospectively.Results:The ratio of male-to-female in five recipients was 4: 1 and the average age 64(56-73) years.Three cases were idiopathic pulmonary fibrosis concomitant with small cell carcinoma (including 1 case of combined small cell carcinoma), bronchiectasis plus carcinoid carcinoma (n=1) and connective tissue disease-related fibrosis plus carcinoid carcinoma (n=1). HE stain indicated that morphological spectrum changed from neuroendocrine cell hyperplasia to carcinoid in transplanted lung of bronchiectasis.Immunohistochemical stain indicated that neuroendocrine markers CgA, Syn, CD56 and epithelial markers AE1/AE3, TTF-1 were positive for small cell carcinoma and carcinoid.Ki-67 index of small cell carcinoma (n=2) and combined small cell carcinoma (n=1) was 80% and Ki-67 index of carcinoid (n=2) was ≤1%.Until the last follow-up, 3/5 patients survived and the remaining 2 died of Klebsiella pneumoniae, Corynebacterium striatus and Acinetobacter baumannii infections at Days 33 and 196 post-transplantation.Conclusions:Neuroendocrine carcinoma in transplanted lung is more common in elderly males and end-stage lung disease is mostly idiopathic pulmonary fibrosis.Small cell carcinoma is a major type of neuroendocrine carcinoma.Specific neuroendocrine markers and TTF-1 aid in a definite diagnosis of neuroendocrine carcinoma.Postoperative infection is an important prognostic factor.

The effect of percutaneous transluminal angioplasty in the treatment of autogenous arteriovenous fistula stenosis and influencing factors of restenosis/loss of function after PTA / 中国医师杂志

Objective:To analyze the effect of percutaneous transluminal angioplasty (PTA) in the treatment of autogenous arteriovenous fistula (AVF) stenosis and influcing factors of restenosis/loss of function after PTA.Methods:The medical records of 104 patients with AVF stenosis treated by PTA in People′s Hospital of Huadu District from March 2019 to July 2020 and the 1-year follow-up were retrospectively analyzed. Kaplan-meier curves were used to analyze the primary patency rates at 3 months, 6 months and 1 year. COX regression was used to analyze the influencing factors of restenosis/loss of function after PTA.Results:The primary patency rates of AVF at 3, 6 and 12 months after PTA were 86.2%, 83.2% and 64.7%, respectively. Guide wire entry into the distal end of radial artery, the use of two balloons in stepwise mode, postoperative dilatation diameter, and dialysis blood flow after PTA were independent risk factors for restenosis/loss of fuction after PTA for AVF stenosis (all P<0.05). Conclusions:The guide wire into the distal end of the artery and passive use of more than two balloons are important factors affecting AVF restenosis/loss of function after PTA .
