BACKGROUND: Previous studies have demonstrated that the well combination of decellularized matrix and appropriate seeded cells could construct a tissue-engineered kidney.OBJECTIVE: To review advances in kidney tissue engineering and decellularized matrix.METHODS: The first author retrieved CNKI, Wanfang and PubMed databases for articles addressing kidney tissue engineering published from January 1996 to April 2016. The key words were decellularized matrix,extracellular matrix,tissue engineering, kidney, seeded cells in English and Chinese,respectively.RESULTS AND CONCLUSION: The decellularized matrix loses its immunogenicity due to the removal of cellular components, while it retains the important bioactive components of the extracellular matrix and the ultrastructure of the tissues and organs, making it more and more important in kidney tissue engineering. The decellularized matrix especially exerts an important role in the tissue-engineered construction of the entire kidney as driven by recently emerging all-organ acellular cell technology. Remarkable advances in kidney tissue engineering and decellularized matrix have been made in recent years, and realized the construction of a certain functional tissue-engineered kidney. However, there are still many challenges on the way to construct a completely functional tissue-engineered kidney.BACKGROUND: Previous studies have demonstrated that the well combination of decellularized matrix and appropriate seeded cells could construct a tissue-engineered kidney.OBJECTIVE: To review advances in kidney tissue engineering and decellularized matrix.METHODS: The first author retrieved CNKI, Wanfang and PubMed databases for articles addressing kidney tissue engineering published from January 1996 to April 2016.

Objective To compare the early outcomes of laparoscopic and open resection and evaluate the safety and feasibility of laparoscopic surgery in patients with colorectal cancer aged ≥ 70 years.Methods A total of 91 consecutive patients with colorectal adenocarcinoma underwent surgery in Yizheng City People's Hospital between Jan.2009 and Dec.2015.In 91 patients included in this study,38 received laparoscopic surgery and 53 underwent open surgery.Main outcome measures were clinical data,postoperative recovery status and short-term outcomes.Results There were no significant differences between two groups with respect to demographic indicators,clinicopathological results and chronic comorbidities had no significant difference between two groups.No death cases occured in both groups.One patient in the laparoscopic group required conversion to open surgery due to ureteral injury.Laparoscopic surgery was associated with significantly longer operating time [(238 ± 71.3) minutes vs (175 ± 60.8) minutes,P ＜ 0.001],less estimated blood loss [(145 ± 58 ml) vs (186 ± 45) ml,P ＜ 0.001)],a shorter postoperative hospital stay [(11.9 ± 3.9) days vs (14.5 ± 3.7) days],lower overall postoperative complication rate (23.7％ vs 45.3％,P =0.035),wound-related complication rate (2.6％ vs 22.6％,P =0.017) when compared with open surgery.Quality of surgical specimen,lymph nodes harvested were not significantly different between two groups.Conclusion Laparoscopic colorectal cancer surgery is safe and feasible in elderly patients,associated with better short-term outcomes when compared with open surgery.

Objective:To explore the clinical value of laparoscopic abdominoperineal resection(LAPR) with pelvic peritoneum closure for patients with low rectal cancer.Methods:The clinicopathological data of 90 patients with low rectal cancer who underwent laparoscopic abdominoperineal resection from Mar 2014 to Jan 2019 at the Subei People's Hospital of Jiangsu Province were retrospectively analyzed. These patients were divided into closed pelvic floor peritoneum group (study group, n=42) and without pelvic floor peritoneum group (control group, n=48) . Results:The postoperative hospital stay of the study group was shorter than that of the control group[(10.8±3.0) d vs. (12.4±3.1) d, t=2.569, P=0.013]. There was no statistically significant difference in the operation time , intraoperative blood loss , time to first flatus ,first time of getting out of bed between the two groups. Perineal incision infection and perineal incision dehiscence occurred in 2 cases and 1 case in the study group, and 10 cases and 9 cases in the control group respectively (χ 2= 5.007, P=0.025; χ 2=6.077, P=0.033). In the study group, there were 0 cases of perineal hernia, 1 case of pelvic floor peritoneal hernia and 2 cases of adhesive intestinal obstruction, while those in the control group were 7 cases, 8 cases and 9 cases, respectively (χ 2=6.642, P=0.013; χ 2=5.079, P=0.033; χ 2=4.085, P=0.043). Conclusion:Laparoscopic abdominoperineal resection with pelvic peritoneum closure significantly reduces the incidence of postoperative perineal-related complications and shorten postoperative hospital stay.

BACKGROUND:Orthopedic osteotomy at the apex of kyphosis is best for treatment of ankylosing spondylitis from a biomechanical aspect, but there is a high risk for intraoperative spinal cord injury.
OBJECTIVE:To explore the clinical efficacy of vertebral plate osteotomy+vertebra osteotomy+long-segment pedicle screw fixation in the treatment of ankylosing spondylitis with kyphotic deformity.
METHODS:Thirty-six patients with ankylosing spondylitis were subjected to pedicle subtraction osteotomy and Smith-Peterson osteotomy, and then fol owed up for 3 months to 2 years.
RESULTS AND CONCLUSION:After implantation, sagittal imbalance did not occur in 36 patients, and the improvement rate of sagittal imbalance was 64%. The improvement rates of thoracolumbar kyphosis and chin-brow vertical angle were 60%and 98%, respectively. The pain relief rate was 64%, and the Oswestry Disability Index was 95%. There were no pul ed nails, broken nails and broken robs after implantation. These findings indicate that the combination of selective osteotomy technique and long-segment internal fixation can achieve stable fixation effects, prevent sagittal imbalance, and avoid the occurrence of pul ing nails, breaking nails and breaking robs caused by osteoporosis.

BACKGROUND:Clinical treatment of hemivertebrae-induced congenital scoliosis is a complex medical problem. OBJECTIVE:To find the optimal treatment for hemivertebrae accompanied by congenital scoliosis.
METHODS:Total y 142 hemivertebrae patients who had received surgical treatment in the Department of Orthopedics, the 306 Hospital of Chinese PLA, China from 2010 to 2012 were enrol ed. The main surgical treatment was hemivertebrae resection and bone fusion with internal fixation, apical osteotomy for severe scoliosis and spinal shortening with internal fixation, one-stage posterior thoracolumbar osteotomy with internal fixation, spinal decompression with internal fixation.
RESULTS AND CONCLUSION:After treatment, the average correction rate was 70.9%for scoliosis and 71.7%for kyphosis. The fol ow-up period was 14-35 months, with an average of 23.4 months. By the end of the final fol ow-up, the loss rate for Cobb’s angle was 7.3%for scoliosis and 7.7%for kyphosis. Fol ow-up X-ray films showed bone fusion and internal fixation without loosening, fracture, and decompensation. Implementation of one-stage posterior thoracolumbar osteotomy with internal fixation can effectively correct hemivertebrae-induced kyphoscoliosis to obtain a satisfactory spinal sagittal and coronal balance.
