OBJECTIVETo investigate and research WHOQOL-BREF evaluation of the clinical effect of application of moxibustion for treatment of knee osteoarthritis, to provide clinical according for the treatment.

METHODSFrom January 2007 to June 2008, 90 cases of knee osteoarthritis were randomly divided into treatment group and control group. In treatment group there were 45 cases included 16 males and 29 females with an average age of (62.5 +/- 7.4) years; the average course was (26.5 +/- 14.6) months; Lysholm score of knee function before treatment was (65.5 +/- 3.5) hours on average. In control group, there were 45 cases included 11 males and 34 females with an average age of (62.5 +/- 9.3) years;the average course was (24.6 +/- 16.6) months; Lysholm score of knee function before treatment was (66.3 +/- 2.3) hours on average. Applied Quality of Life Scale WHOQOL-BREF in line with the inclusion criteria of the study evaluation. While applied Lysholm scoring of knee joint for supporting the evaluation criteria. All data were statistical analyzed by package SPSS 11.5.

RESULTSMoxibustion was applied to treat the knee osteoarthritis and the quality of life was evaluated according to the WHOQOL-BREF scale score. The scores of the physical state, psychological state, as well as their own general health status of subjective feeling, and so on in treatment was significantly higher than that in control group (P < 0.05). According to Lysholm scoring, the score in treatment group was significantly higher than that of control group, too (t = 0.65, P < 0.05).

CONCLUSIONApplication of moxibustion for treatment of knee osteoarthritis is a simple, economical and practical, and can avoid the further development of the disease, but also to improve the joint function and improve quality of life.

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.

OBJECTIVETo explore the external fixation for treatment of supracondylar femoral fractures after total knee replacement.

METHODSFrom June 2005 to July 2007, 7 cases of supracondylar femoral fracture after total knee replacement were treated with external fixation included 4 males and 3 females with an average age of 71 years ranging from 55 to 85 years. The fracture healing were observed and the knee function were evaluated by the HSS scoring.

RESULTSAll patients were followed-up for 6 to 23 months with an average of 12.5 months. The fracture healing time was from 6 to 12 weeks after operation (averaged 8.5 weeks). During the followed-up period, there were no infection and loosening, only one case occurred nail crossing delayed healing of skin. The HSS knee score was (60.6 +/- 16.0) before treatment and (77.6 +/- 11.6) after treatment according to HSS knee score criteria, the results were excellent in 2 cases, good in 4, and fair in 1.

CONCLUSIONApplication of external fixation for treatment of supracondylar femoral fracture after total knee replacement, especially in poor physical condition, high age patients is a more appropriate treatment.

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.

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.

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.

OBJECTIVETo deduce all potential ligands undiscovered experimentally by searching all the proteins containing same C-termini, which can bind a certain PDZ domain.

METHODSWe developed a JAVA program for searching short exact sequence matches at C-terminus. According to the known C-termini, which PDZ domains recognized experimentally, Swissprot database has been searched by this program for all potential ligands.

RESULTSSome PDZ domains may have more potential ligand proteins, which are undiscovered yet experimentally. These bioinformatic results also provide clues for studying functions of hypothetical proteins and PDZ domains' protein interactions in many different organisms.

CONCLUSIONThe results may provide useful clues for discovering potential functions of hypothetical proteins and new functions of known proteins.
