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 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.

OBJECTIVE: To identify and analyze drug sensitivity of Corynebacterium glucuronolyticum iscolated from clinic, and to provide reference for clinical drug use. METHODS: Two strains isolated from the urine specimens of urolithiasis-induced urinary tract infection patients in our hospital were inoculated into Columbia blood plate and the MacConkey plate. The growth of strains was observed and counted. Protein mass spectrometry of strains was detected by MALDI-TOF-MS. DNA of strains was extracted, and PCR was used to amplify the 16S ribosome RNA (rRNA) sequence. Bi-directional sequencing of 1 500 bp target bands was conducted. Blast comparison between it and GenBank database was conducted to identify bacterial strain. Drug resistance of 2 strains was monitored by Etest assay. RESULTS: Two strains grew on the Columbia blood plate (with colony forming unit >105 CFU/mL) and did not grow on the MacConkey plate. Two strains were Gram-positive Corynebacterium and showed palisading or eight type arrangement. Two strains were C. glucuronolyticum by MALDI-TOF-MS identification, with reliability of 99. 9%. The characteristic peaks of m/z 2 431, 3 089, 3 364, 3 378, 4 200, 5 508, 6 302, 6 637, 6 730, 6 946, 12 603 appeared. Blast comparison showed that the sequence homology of 2 strains compared with C. glucuronolyticum strain known in GenBank were higher than 98 %. Results of drug sensitivity test showed that strain 1 was resistant to ceftriaxone and ciprofloxacin, and sensitive to 14 other antibiotics as penicillin G; strain 2 was resistant to ceftriaxone, erythromycin, ciprofloxacin, tetracycline and clindamycin, moderately sensitive to cefotaxime, and sensitive to 10 other antibiotics. CONCLUSIONS: Two strains are C. glucuronolyticum, and drug resistance of them to commonly used antibiotics is different. The strains are rare pathogen of urinary tract and show multidrug resistance. Antibiotics should be selected according to the results of strain identification and drug sensitivity test.
