Status of a New Model of ERCP Training in China: A Nationwide Survey of Standardized Training for ERCP Procedure (STEP) Programs.

Aims: ERCP training should adapt to the rapid development of ERCP technology and indications. China has a large population and vast land area, but ERCP training resources are insufficient. To make effective use of scarce ERCP training resources, the Standardized Training for ERCP Procedure (STEP) program was launched as a pilot trial.

[Action mechanism of Huotu Jiji Pellets in the treatment of erectile dysfunction: An exploration based on network pharmacology and molecular docking].

Objective: To explore the potential action mechanism of Huotu Jiji Pellets (HJP) in the treatment of erectile dysfunction (ED) based on network pharmacology and molecular docking.

Methods: We identified the main effective compounds and active molecular targets of HJP from the database of Traditional Chinese Medicine Systems Pharmacology (TCMSP) and Integrative Pharmacology-Based Research Platform of Traditional Chinese Medicine (TCMIP) and the therapeutic target genes of ED from the databases of Genecards. Then we obtained the common targets of HJP and ED using the Venny software, constructed a protein-protein interaction (PPI) network of HJP acting on ED, and screened out the core targets with the Cytoscape software.

Endotherapy for the Proximal Migration of Pancreatic Stents: A Systematic Review.

Objectives: Proximal migration is one of the complications after pancreatic duct stenting. This study aimed to determine the incidence of proximal migration and to analyze the rescue methods.

Materials And Methods: A search was performed in MEDLINE/Embase database.

[Exploring the mechanisms of ferroptosis in non-obstructive azoospermia based on bioinformatics and machine learning].

Objective: To explor the potential mechanisms of ferroptosis involvement in non-obstructive azoospermia based on bioinformatics and machine learning methods.

Methods: To obtain disease-related datasets and ferroptosis-related genes, we utilized the GEO database and FerrDb database, respectively. Using the R software, the disease dataset was subjected to normalization, differential analysis, and GO and KEGG enrichment analysis.

Endoscopic retrieval of a migrated pancreatic stent stuck at both ends: A case report.

Background: Endoscopic pancreatic stenting is an effective way to relieve the stricture of the pancreatic duct. However, proximal stent migration presents a threat to the patient and a challenge to the doctor. The limited space in the pancreatic duct often prevents the operation of suitable devices for stent removal.

Classification of Early-Onset and Late-Onset Idiopathic Chronic Pancreatitis Needs Reconsideration.

Bimodal classification of idiopathic chronic pancreatitis (ICP) into early-onset (<35 years) and late-onset (>35 years) ICP was proposed in 1994 based on a study of 66 patients. However, bimodal distribution wasn't sufficiently demonstrated. Our objective was to examine the validity and relevance of the age-based bimodal classification of ICP.

Long-term results of a randomized phase III trial of TPF induction chemotherapy followed by surgery and radiation in locally advanced oral squamous cell carcinoma.

Previously, we conducted a randomized phase III trial of TPF (docetaxel, cisplatin, and 5-fluorouracil) induction chemotherapy in surgically managed locally advanced oral squamous cell carcinoma (OSCC) and found no improvement in overall survival. This study reports long-term follow-up results from our initial trial. All patients had clinical stage III or IVA locally advanced OSCC.

Randomized phase III trial of induction chemotherapy with docetaxel, cisplatin, and fluorouracil followed by surgery versus up-front surgery in locally advanced resectable oral squamous cell carcinoma.

Purpose: To evaluate induction chemotherapy with docetaxel, cisplatin, and fluorouracil (TPF) followed by surgery and postoperative radiotherapy versus up-front surgery and postoperative radiotherapy in patients with locally advanced resectable oral squamous cell carcinoma (OSCC).

Patients And Methods: A prospective open-label phase III trial was conducted. Eligibility criteria included untreated stage III or IVA locally advanced resectable OSCC.

[The effect of MAB225 on radiosensitivity of salivary gland adenoid cystic carcinoma].

Purpose: To observe the effect of epidermal growth factor receptor's monoclonal antibody(MAB225) on radiosensitivity of salivary gland adenoid cystic carcinoma cell.

Methods: Bi-fluorescence stain ,MTT test and fluorescence flow cytometry(FCM) were used to observe the apoptosis rate and radiosensitizing effect for MAB225 on ACC-2 cell.SPSS11.

[The mechanism of MAb225 regulating radiosensitivity of Tca8113 cell].

Purpose: The objective of this study was to investigate the mechanism of MAb225 regulating radiosensitivity of Tca8113 cells.

Methods: Tca8113 cells were treated with MAb225 of different concentrations. The apoptosis rate was analysed by FCM and bi-fluorescence stain, the repair of DNA damage after radiation was analysed by single cell gel electrophoresis, cells redistribution in each phase of cell cycle was analysed by FCM, and GSH level of cell were assessed by spectrophotometer.

[Effect of MAb225 on radiosensitivity of Tca8113 tongue squamous cell carcinoma].

Objective: The purpose of this study was to invest the effect of epidermal growth factor receptor monoclonal antibody MAb225 on radiosensitivity of tongue squamous cell carcinoma cell Tca8113.

Methods: Tca8113 cells were treated with different concentrations of MAb225. Radiation dose survival curve was generated from clonogenic survival assay.

[Radiotherapy for immediate reconstruction of mandibular defects with the titanium plate after tumor resection of mandible].

Objective: To study the influence of radiotherapy on immediate reconstruction with the titanium plate after resection of mandible in oral cancer patients.

Methods: Fifty-eight cases (radiation group, 30 patients and control group, 28 patients) with titanium plate for immediate reconstruction of mandibular defects were observed from January, 1997 to May, 2002. The patients of radiation group underwent radiotherapy with total doses of 4,050 - 6,540 cGy (mean 5,495 cGy).

[Analysis for therapy and prognosis of undifferentiated carcinoma with lymphoid stroma in salivary gland].

Objective: To analyse the clinical characteristic, evolution and prognosis of undifferentiated carcinoma with lymphoid stroma(malignant lymphoepithelial lesions, MLEL) in salivary gland.

Methods: During 1989 and 1997, 21 cases of MLEL in salivary gland were treated. The primary site was parotid in 18 cases, palate minor salivary gland in 2 cases and submandibular gland in 1 case.
