We developed a novel method for constructing nearly random peptide library. Genomic DNAs extracted from tissue or cells of large genome species were digested with frequent cutter to produce short DNA fragments. These short fragments can be considered nearly random. Nearly random peptide libraries can be constructed by cloning the short fragments into appropriate expression vectors and transformation into host cells. Genomic DNA from one species can be digested with different restriction enzymes and ligated to different reading frames to produce several different libraries. In this study, we digested tobacco genomic DNA with two enzymes and cloned into three different reading frames to make totally six nearly random peptide libraries.

Laparoscopic radical surgery for rectal can-cer involves total mesorectal excision (TME), D 3 lymphadenectomy, and pelvic autonomic nerve preservation, the goal of which is trying to achieve completely radical cure for cancer and urogenital function preservation. In the actual operation procedure, the understanding of fascial anatomy in abdominal and pelvic cavity will help us to improve the quality of TME surgery for rectal cancer and to preserve the pelvic autonomic nerves. When entering the pelvic cavity, the identification of fascia propria of mesorectum, visceral fascia, pre-hypogastric nerve fascia, presacral fascia, ligament structures around the rectum and the Denonvilliers′ fascia in front of the rectum will help us to protect the pelvic autonomic nerves and avoid surgical injury. So the authors focus on how to identify the pelvic fascia structure clearly in laparoscopic radical resection for rectal cancer, furthermore, to master the concepts of fascia anatomy to realize TME for rectal cancer and to achieve pelvic autonomic nerve preservation.

4K laparoscopy brings opportunities and challenges to the development of rectal surgery. 4K laparoscopy can truly provide the structure of abdominal and pelvic fascia, so that surgeons can see more subtle anatomical structure. The clear and real picture under 4K laparoscopic system can reduce visual fatigue of surgeons, which make the operation easier and safer. Radical resection of right colon cancer includes complete mesocolic excision and D 3 lymphadenectomy. Through 4K laparoscopic system, surgeons can easily observe the fascia structure of right mesocolon and its mesenteric bed, distinguish the vascular anatomical relationship at the mesenteric root, which make D 3 lymphadenectomy safer with dissection of lymph nodes completely. The authors comprehensively analyze the related research progress at home and abroad, and systematically elaborate the region of dissection and significance of 4K laparoscopic right hemicolectomy for right colon cancer.

Digestive tract reconstruction with side-to-side esophagojejunostomy is one of the most commonly used digestive tract reconstruction methods after laparoscopic total gastrectomy. It does not need an auxiliary incision. The linear stapler is used to directly enter the abdominal cavity through the Trocar to perform side-to-side anastomosis of esophagojejunostomy. The common hole can be closed by hand suture or linear stapler. 4K laparoscopy can present a clearer and more realistic view to the operators, so as to realize side-to-side esophagojejunostomy more accurately, to reduce the postoperative anastomo-tic related complications and improve the safety of the operation. This article will elaborate the technical key points and difficulties of esophagojejunostomy in 4K laparoscopic total gastrectomy, as well as the prevention and treatment of anastomotic related complications.
