Totally laparoscopic surgery for choledochal cysts with hand‑sewn Roux‑en‑Y reconstruction in a pediatric population.

Cyst excision and Roux-en-Y hepaticojejunostomy (RYHJ) is the standard treatment for choledochal cysts (CCs). In the present study, the results of totally laparoscopic surgery for CCs (TLCCs) in a pediatric population were evaluated. The clinical data of 28 children with CCs between June 2020 and June 2023 were retrospectively reviewed.

Non-stapled, total laparoscopic Roux-en-Y anastomosis: A safe and effective procedure for radical pediatric choledochal cyst excision.

Background: Laparoscopic or robot-assisted surgery has become the main pediatric minimal invasive surgery for a choledochal cyst (CDC). However, the Roux-en-Y jejunal limb was created extracorporeally in most reports and intracorporeally in a few reports using an endoscopic stapler.

Objectives/methods: To investigate the safety and feasibility of non-stapled laparoscopic Roux-en-Y reconstruction in the radical treatment of congenital choledochal cysts (CDC).

Textbook outcome in gallbladder carcinoma after curative-intent resection: a 10-year retrospective single-center study.

Background: Textbook outcome (TO) can guide decision-making among patients and clinicians during preoperative patient selection and postoperative quality improvement. We explored the factors associated with achieving a TO for gallbladder carcinoma (GBC) after curative-intent resection and analyzed the effect of adjuvant chemotherapy (ACT) on TO and non-TO patients.

Methods: A total of 540 patients who underwent curative-intent resection for GBC at the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2020 were retrospectively analyzed.

Preoperative Fibrinogen Albumin Ratio is an Effective Biomarker for Prognostic Evaluation of Gallbladder Carcinoma After Radical Resection: A 10-Year Retrospective Study at a Single Center.

Background: To explore and screen preoperative serum immune response level-related biomarkers with better prognostic ability and developed a prognostic model for decision-making in clinical practice for gallbladder carcinoma (GBC) patients.

Methods: A total of 427 patients who underwent radical resection for GBC in the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2020 were retrospectively analyzed. Time-dependent receiver operating characteristic (time-ROC) was performed to determine the prognostic predictive power of preoperative biomarkers.

Laparoscopic surgery of intra-abdominal lymphatic malformation in children.

Lymphatic malformation (LM) in the abdomen is uncommon in children, and the standard treatment is surgical excision. The present study aimed to evaluate the safety and efficacy of laparoscopic surgery of intra-abdominal LM in a pediatric population. The medical records of 10 children with intra-abdominal LM treated by laparoscopic resection from March 2017 to June 2021 in The Second Affiliated Hospital of Xi'an Jiaotong University (Xi'an, China) were retrospectively reviewed.

Urban Air Pollution and Mental Stress: A Nationwide Study of University Students in China.

Studies exploring the relationship between air pollution levels and mental stress have rarely been done, and no studies have been done comparing university student mental stress levels based on regional air pollution levels. The objective of this study was to evaluate the association between air pollution and mental stress among university students. Participants were 11,942 students, who were identified through a multistage survey sampling process conducted in 50 universities.

Comprehensive analysis of genomic mutation signature and tumor mutation burden for prognosis of intrahepatic cholangiocarcinoma.

Background: Intrahepatic cholangiocarcinoma (iCCA) is a highly lethal malignancy of the biliary tract. Analysis of somatic mutational profiling can reveal new prognostic markers and actionable treatment targets. In this study, we explored the utility of genomic mutation signature and tumor mutation burden (TMB) in predicting prognosis in iCCA patients.

Optimal number of harvested lymph nodes for curatively resected gallbladder adenocarcinoma based on a Bayesian network model.

Background And Objectives: To identify the optimal range and the minimum number of lymph nodes (LNs) to be examined to maximize survival time of patients with curatively resected gallbladder adenocarcinoma (GBAC).

Methods: Data were collected from the surveillance, epidemiology, and end results database on patients with GBAC who underwent curative resection between 2004 and 2015. A Bayesian network (BN) model was constructed to identify the optimal range of harvested LNs.

Violent Injuries Among College Students in China: An Exploration of Gender Mental Stress Model.

The purpose of this study was to explore the gender-specific mental stress model of violent injuries among Chinese college students. A cross-sectional, multistage sampling process was employed to recruit a total of 5025 college students from 22 universities in China. Survey respondents reported their exposure to violent injuries and noted individual and environmental factors that could relate to violent injuries.

Transient Absorption Microscopy of Layered Crystal AsSbS.

We introduce getchellite as a new layered material for fabrication of two-dimensional van der Waals materials and heterostructures. Nanofilms of AsSbS were fabricated by mechanical exfoliation. Transient absorption spectroscopy measurements identified a direct bandgap at about 710 nm, which is close to the ideal single-junction photovoltaic bandgap.

[Study on nanoparticles in Yangtze Estuary].

Filtration and cross-flow ultrafiltration (CFUF) was applied for the effective separation of NPs in the Yangtze Estuary. The physiochemical properties of NP were characterized, and their relationships with environmental factors were further studied in the present study. The results show that NP size in Yangtze Estuary ranged from 69.

Sorption behavior of phenanthrene in Yangtze estuarine sediments: sequential separation.

In the present study, phenanthrene was chosen as the probe compound for determining the sorption of PAHs in sediments from Yangtze estuary and nearby coastal area, China. Sorption isotherms were fitted well by the Freundlich and dual models, respectively. Selected sediments were further sequentially separated to remove the carbonate and organic carbon (OC).
