OBJECTIVETo compare the clinical curative effect of thoracolumbar burst fracture treated by the posterior unilateral approach corpectomy fusion screw-rod fixation and anterior corpectomy bone fusion screw plate fixation.
METHODSFrom January 2008 to May 2014,36 cases of thoracolumbar burst fracture underwent operation of decompression, fusion, and internal fixation was retrospective analyzed. Among them, 16 patients were treated through posterior approach as posterior group, including 13 males and 3 females aged from 37 to 62 years old; 9 cases caused by falling injury, 3 cases by traffic accident injury,4 cases by heavy aboved;the injury segment was on T₁₂ in 2 cases, L₁ in 5 cases, L₂ in 7 cases, L₃ in 2 cases; according ASIA grade, 3 cases were grade A, 2 cases were grade B, 2 cases were grade C, 5 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 5 to 15 days. Other 20 patients were treated through anterior-lateral approach as anterior-lateral group, including 15 males and 5 females with age from 27 to 62 years old; 12 cases caused by falling injury, 4 cases by traffic accident injury, 4 cases by heavy aboved; the injury segment was on T₁₂ in 2 cases, L₁, in 7 cases, L₂ in 9 cases, L₃ in 2 cases; for ASIA grade: 4 cases were grade A, 2 cases were grade B, 4 cases were grade C, 6 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 4 to 12 days. The operation time, bleeding during operation and postoperative drainage volume were observed in two groups,and the changes of nerve function of ASIA grade, clinical efficacy,improved degree of thoracic and lumbar lordosis,and bony fusion were compared between two groups.
RESULTSAll patients were followed up from 12 to 24 months with an average of (15.8 ± 3.3) months. The operation time, bleeding during operation, and postoperative drainage volume had no significant different between two groups (P > 0.05). As compared with preoperative, ASIA grade of two groups at last follow-up had statistically significantly different (P < 0.01), the neural function of two groups after operation was recovered for different extent. The JOA score of two groups was compared between last follow-up and preoperative, the difference had statistically significant (P < 0.01), the two groups showed good clinical effect. The clinical results of ASIA grade, JOA score and RIS had no significant differences between two groups. All patients of two groups were obtained fusion. Thoracic and lumbar lordosis angle improvement degree had no significant difference between two groups ,it bad significant difference had statistical significance compared with preoperative, the two approaches could effectively restore the spinal sequence.
CONCLUSIONFor patients with thoracolumbar burst fracture just treated by anterior decompression and reconstruction of anterior column, according to the degree of operation performer' skill proficiency and the patient' condition to choose, but for patients must performed the spinal canal decompression anterior and posterior, the three column-reconstruction to required anterior-posterior approach, the posterior unilateral approach corpectomy fusion screw-rod fixation obviously shorten operation time, reduce the operation wound, it is worth the clinical promotion.

OBJECTIVE:
To investigate the expression and significance of miRNA-324-3p and its target gene WNT2B in tissue specimens of nasopharyngeal carcinoma (NPC) specimens.
METHOD:
qRT-PCR was used to detect the expression of miRNA-324-3p and WNT2B mRNA, and Western blot was applied to assay the expression of WNT2B protein in 39 cases of NPC specimens and 21 cases of non-carcinoma epithelium. The relationship between their expression levels and clinicopathological characteristics and their correlation with clinical pathological parameters was analyzed.
RESULT:
The expression of miRNA-324-3p was significantly down-regulated decreased but WNT2B mRNA/protein increased obviously in NPC specimens (P < 0.01). A negative correlation between miRNA-324-3p and WNT2B was spotted (P < 0.05). The expression levels of these markers were closely correlated with T stage, clinic stage and cervical lymph node metastasis (P < 0.05).
CONCLUSION
The loss of miRNA-324-3p and ectopic WNT2B might co-induce the initiation and progression of NPC.

OBJECTIVEAfter sinboneHT bone replacement (SBR) was implanted in animals, to evaluate the biocompatibility of SBR and compounded in autogenetic bone in the proportion of one to one in order to prepare for the clinical applications in the future.
METHODSBone defects of 10 mm x l0 mm x 2 mm was made at the mandibular of rabbits, then SBR with different granule diameter and autogenetic bone was compounded in the proportion of being applied in the left defects, while autogenetic bone was implanted in the right defects and nothing was used in the right reformed defects. Animals were sacrificed at 2, 4 and 8 weeks respectively. The biologic capacity was evaluated with anatomy, X-rays studies and histology.
RESULTSSBR has better biocompatibility, which can effectively accelerate the reconstruction of bone defects and help the new bone by being compounded with autogenetic bone. It provides the appropriate scaffold or template which would allow cellular infiltration, attachment and multiplication.
CONCLUSIONSBR is a kind of bone substitute material with good biocompatibility. SBR compounded with self-bone has a better regeneration function.

BACKGROUNDNosocomial infection in early post-transplantation period is a tough problem for kidney transplantation. Few reports have explored the relations between biochemical parameters and nosocomial infection in kidney transplantation. This retrospective study was carried out to describe the characteristics of nosocomial infection in the very early period of kidney transplantation and to determine the risk factors in biochemical parameters and their alterations.
METHODSPatients who underwent their first kidney transplantation from January 2001 to March 2009 in Beijing Chao-Yang Hospital were recruited and the nosocomial infectious episodes were collected for this study. Gender, age, donor type, delayed graft function (DGF) and biochemical parameters such as serum uric acid, lipids files and albumin on day 0 (before transplantation) and day 1 (24 hours after transplantation) and their changes were analyzed with Logistic regression models for nosocomial infection.
RESULTSA total of 405 patients (315 men and 90 women) were involved in this study. There were 80 patients experiencing 113 infection episodes and 105 strains of microorganism were identified. In univariate analysis, there were significant differences in DGF, albumin on day 0, lipoprotein (a) (Lp(a)) on day 1, change in low density lipoprotein-cholesterol (LDL-C, day 1-day 0) and change in uric acid (day 1-day 0) between nosocomial infection patients and noninfectious patients (P < 0.05). In multivariate analysis, change in uric acid (day 1-day 0) (OR 5.139, 95%CI 1.176-22.465, P < 0.05), change in LDL-C (day 1-day 0) (OR 4.179, 95%CI 1.375-12.703, P < 0.05) and DGF (OR 14.409, 95%CI 1.603-129.522, P < 0.05) were identified as independent risk factors for nosocomial infection in kidney transplantation.
CONCLUSIONSMost nosocomial infections in early postoperative period of kidney transplantation are bacterial, especially with Gram-negative bacteria. The most common infection sites are respiratory tract, urinary tract and surgical site. DGF, decrease of LDL-C and increase of uric acid could increase the risk for nosocomial infections.

OBJECTIVETo investigate the approach and efficacy of dealing the rectal ligament in resection of rectal cancer in obese male patients.
METHODSA total of 92 patients (BMI>25 kg/m(2)) undergoing resection of rectal cancer from December 2008 to December 2010 in Henan Tumor hospital were assigned into 2 groups according to the surgical technique, the modified group (paralleled clipping of rectal ligament, 48 patients) and traditional group (44 patients). Operative time, intra-operational bleeding, rectal ulceration, ureteral injury, mesorectal integrity, and positive rate of lateral margin of pelvic wall were compared between two groups.
RESULTSThe operative time was (66.9±99.8) min in modified group, which was significantly shorter than that in traditional group [(125.4±12.2) min, P=0.000]. Intra-operative bleeding was (160.3±27.2) ml in modified group and (150.5±28.5) ml in traditional group (P=0.093). Rectal ulceration rated were 0 and 18.2% (8/44), mesorectal disintegrity rates were 6.2% and 22.7%, pelvic infection rates were 2.1% (1/48) and 20.4 (9/44) in modified and traditional groups respectively, whose differences were all significant (all P<0.05). No ureteral injury and positive margin were found in both two groups.
CONCLUSIONThe approach of paralleled clipping of rectal ligament around the rectum meets the principle of TME, which is simple, safe and effective.

OBJECTIVETo evaluate the association of early diarrhea(postoperative day 1 to 7) and anastomotic leakage after low anterior resection for rectal cancer.
METHODSClinical data of 192 cases (group A, tumor from the anal verge 4-7 cm) from May 2004 to May 2007 and 236 cases(group B) from July 2007 to May 2010 in our hospital who received low anterior resection of rectal cancer were analyzed retrospectively.
RESULTSIn group A, the incidence of early postoperative diarrhea was 19.3%(37/192), of which 9 cases were treated with anti-diarrhea drugs. The morbidity of anastomotic leakage in patients with diarrhea was significantly higher than those without early diarrhea(16.2% vs. 5.2%, P<0.05). In group B, the incidence of early postoperative diarrhea was 16.5%(39/236). All the patients were treated with anti-diarrhea drugs. There was no difference in the morbidity of anastomotic leakage between patients with diarrhea and those without early diarrhea(16.2% vs. 5.2%, P<0.05). There was no difference in early diarrhea between groups A and B(P>0.05). However, the incidence of anastomotic leakage in patients with early diarrhea was lower in group B(P<0.05).
CONCLUSIONSEarly diarrhea after the low anterior resection of rectal cancer may indicate anastomotic leakage. Treatment of early postoperative diarrhea may reduce the risk of anastomotic leakage.
