ABSTRACT
Inguinal hernia is a common surgical disease, and most patients need surgical treatment. In recent years, minimally invasive surgery based on laparoscopy has been popularized in hernia surgery. With the release of clinical guidelines, the progress of instruments and materials, the update of treatment concepts and anatomical knowledge, laparoscopic inguinal hernia repair, especially laparoscopic total extraperitoneal hernia repair (TEP), is developing towards a more accurate and minimally invasive direction. Based on literatures in recent years and combined with clinical practice, the authors explore the advances in clinical application of laparoscopic TEP.
ABSTRACT
Laparoscopic radical resection of transverse colon cancer is a difficult operation, which is featured by large operation area, multiple steps, and many clinical anatomical variations. It requires the concept of complete mesocolic excision. Because of its absolute high-definition picture restoration, the 4K laparoscope can effectively assist in the identification, protection and severance of blood vessels during the operation, and assist in judging the fascia space of the operation. After entering Toldt fascial space through the intermediate approach guided by the superior mesenteric vein, the left, right transverse colon and lower area of mesangium are completely dissected, the upper area of colon, hepatic and splenic flexure are sepearted. The authors summarize practical experiences, investigate the extent of lymph node dissection in 4K laparoscopic radical resection of transverse colon cancer and share surgical experience.
ABSTRACT
Objective To investigate the expression of TLR9 mRNA of peripheral blood mononuclear cells (PBMCs) in patients with acute pancreatitis .Methods Fifty two AP patients with the disease duration in 24 h were collected ,peripheral EDTAK2 coag‐ulation vein blood were collected on the first ,third and fifth day ,then plasma were cryop reserved to detect pancreatic elastase , proinflammatory cytokines and anti‐inflammatory cytokines .Then the peripheral EDTAK2 coagulation vein blood two to three months after treatment were collected in the same method to undertake these tests ,and act as the reference level value .Peripheral blood was collected from 36 acute pancreatitis patients .Three months later ,peripheral blood was collected again from these 36 peo‐ple as controls .PBMCs were isolated by Ficoll‐Hypaque gradient centrifugation .RT‐PCR was adopted to determine the relative con‐tent of the expression of TLR9 mRNA of the PBMCs .Results The relative content of expression of TLR9 mRNA were significant‐ly up‐regulated in the patients with acute pancreatitis ,compared with that of controls (P<0 .05) .The up‐regulated expression of TLR9 mRNA was related to expression of TNF‐a and IL‐1 .Conclusion The up‐regulated expression of TLR9 mRNA in acute pan‐creatitis patients indicates that infective factors might be mediated by TLR 9 .
