Advances in minimally invasive treatment of malignant obstructive jaundice.

Malignant obstructive jaundice (MOJ) encompasses a range of diseases stemming from malignant tumors such as cholangiocarcinoma, pancreatic cancer, and primary liver cancer, among others, which cause obstruction in both intra- and extra-hepatic bile ducts. This obstruction may lead to elevated bilirubin levels, hepatic function impairment, and a low rate of successful surgical resection in clinical settings. There are various minimally invasive treatment options for MOJ, including endoscopic biliary drainage, ultrasound-guided procedures, and percutaneous biliary tract puncture drainage.

Efficiency and safety of laparoscopic left hemihepatectomy: A study of intrathecal extrathecal Glissonean pedicle techniques.

Background: Selective hemihepatic vascular occlusion is utilized in both right and left hemihepatectomies to preserve blood supply to the intact lobe, maintain hemodynamic stability, and mitigate surgical risks. While this technique encompasses both intrathecal and extrathecal Glissonean pedicle transection methods, there is a lack of systematic comparative reports on these two approaches.

Aim: To retrospectively analyze the clinical data of patients with hepatocellular carcinoma (HCC) undergoing laparoscopic anatomical hepatectomy in our hospital to explore the feasibility, safety, and short- and long-term efficacy of extrathecal and intrathecal Glissonean pedicle transection methods in laparoscopic left hemihepatectomy.

Pay attention to the application of indocyanine green fluorescence imaging technology in laparoscopic liver cancer resection.

Traditional laparoscopic liver cancer resection faces challenges, such as difficulties in tumor localization and accurate marking of liver segments, as well as the inability to provide real-time intraoperative navigation. This approach falls short of meeting the demands for precise and anatomical liver resection. The introduction of fluorescence imaging technology, particularly indocyanine green, has demonstrated significant advantages in visualizing bile ducts, tumor localization, segment staining, microscopic lesion display, margin examination, and lymph node visualization.

Subclinical paraganglioma of the retroperitoneum: A case report.

Background: Paraganglioma (PGL) located in the retroperitoneum presents challenges in diagnosis and treatment due to its hidden location, lack of specific symptoms in the early stages, and absence of distinctive manifestations on imaging.

Case Summary: A 56-year-old woman presented with a left upper abdominal mass discovered 1 wk ago during a physical examination. She did not have a history of smoking, alcohol consumption, or other harmful habits, no surgical procedures or infectious diseases, and had a 4-year history of hypertension.

Primary squamous cell carcinoma of the liver: A case report.

Background: Squamous cell carcinoma (SCC) of the liver is rare, and is more commonly found in the skin, rectum, cervical or inguinal lymph nodes.

Case Summary: A 73-year-old man had been experiencing right upper quadrant discomfort for some weeks. He had a 50-year history of smoking and drinking.

Circulating miRNAs as biomarkers for severe acute pancreatitis associated with acute lung injury.

Aim: To identify circulating micro (mi)RNAs as biological markers for prediction of severe acute pancreatitis (SAP) with acute lung injury (ALI).

Methods: Twenty-four serum samples were respectively collected and classified as SAP associated with ALI and SAP without ALI, and the miRNA expression profiles were determined by microarray analysis. These miRNAs were validated by quantitative reverse transcription-polymerase chain reaction, and their putative targets were predicted by the online software TargetScan, miRanda and PicTar database.

[The experiment research on solution refractive index sensor based on tilted fiber Bragg grating].

The present paper analyzes the sensor's basic principle of the bare tilted fiber Bragg grating (TFBG) and surface plasmon resonance sensor (SPR) that deposited nanoscale gold-coating on the surface of the cladding. We simulated the transmission spectrums and some order cladding mode of TFBG in different concentration solutions by Integration and optical fiber grating software OptiGrating. So by the graphic observation and data analysis, a preliminary conclusion was got that in a certain sensing scope, the cladding modes of TFBG shift slightly to right with the increasing the solution refractive index(SRI),and the relation between resonance peak caused by the coupling of core mode and a certain cladding mode and the SRI was linear.

[Clinical research of Bordetella pertussis infection in infants with prolonged cough].

Objective: To explore the prevalence of Bordetella pertussis (B. pertussis) infection in unvaccinated or incomplete vaccinated infants with cough for a prolonged duration.

Methods: The serum samples and nasopharyngeal secretions were collected from 176 patients with cough for a prolonged duration ( ≥ 2 weeks) from 2011 to 2012 at Children's Hospital Affiliated to Capital Institute of Pediatrics.

[Survey of pertussis infection in infants aged under 3 months with persistent cough].

Objective: To explore the prevalence of pertussis in hospitalized infants aged under 3 months with persistent cough.

Methods: The nasopharyngeal secretions and serum samples were collected from hospitalized infants aged under 3 months with cough for over 2 weeks from January 2011 to January 2012. The samples of nasopharyngeal secretion were suctioned and collected.
