Objective To observe the early ultrastructural changes of the optic nerves after the brain impact injury. Methods Eighteen 15-week-old Wistar rats were used in the air-pressure brain impact injury examination. All of the rats underwent the procedures of right-parietal-bone fenestration after abdominal cavity anesthesia with 1% sodium pentolbarbital (45 mg/kg), and then they were divided randomly into 3 groups, i.e., mild injury group (8 rats) underwent with 7 kg of air pressure in distance of 11 cm; severe injury group (8 rats) with 7 kg of airpressure in distance of 8 cm; and control group (2 rats) underwent with the parietal-bone fenestration but without impact injury.The ultrastructural changes of the optic nerves were observed 1, 6, 24, and 72 hours after the injury by electron microscopy. Results The difference of ultrastructural changes of optic nerve was not obvious in wild injury group and the control group, and the lanthanum nitrate was only found in the blood vessels in optic nerve. The lanthanum nitrate entered the nerve stroma 1 hour after severe and increased as time goes on. Simultaneously, displayed dilatation of endoplasmic reticulum, cavitation and tumefaction of mitochondrion, vacuolation of nerve stroma, and vacuolation of some axis-cylinder were seen in the glial cells. Conclusion The brain impact injury may cause ultrastructural changes of the optic nerve and increase of permeability of blood vessels.

0.05), but not in other brain regions. The number of GFAP-immunopositive cells of the E.coli-treated pups was markedly increased in periventricular white matter and hippocampus at P7 compared with the control group (P0.05). CONCLUSION: Intrauterine infection induces an increased expression of GFAP in the neonatal brain. [

Purpose To investigate the protein expression of p53 and E-cadherin in gastric adenocarcinoma and the effects of them and the clinicopathological parameters on prognosis of patients.Methods Expression of p53,E-cadherin in 150 cases of gastric adenocarcinoma was detected by tissue microarray and immunohistochemistry.The effects of them and the clinicopathological parameters on the prognosis of patients were studied by Kaplan-Meier method to calculate and compare the cumulative survival rate and postoperative mean survival time.Multivariate analysis was also performed by COX regression.Results The positive rate of p53 and E-cadherin expression in 150 cases of gastric adenocarcinoma was 31.3% and 91.3%,respectively.74 cases were followed up, and the 1-,3-,and 5-year survival rates were 83.8%,70.3% and 63.5%,respectively.The invasion, lymph node status and pTNM stages were prognostic factors;multivariate analysis revealed that p53,age and lymph node status were independent prognostic invasion, lymph node status and pTNM stages are important prognostic factors in gastric adenocarcinoma. Nevertheless, E-cadherin and histological classification are not prognostic factors.

Background and purpose:Epithelial ovarian cancer has the highest mortality rate of gynecologic cancers and overall survival rates have improved little in the last 20 to 30 years. CXXC ifnger protein 5 (CXXC5) plays an important role in AML (acute myeloid leukemia) and MDS (myelodysplasia). However, little is known about its clinical signiifcance and biological function in epithelial ovarian cancer. This study aimed to investigate the expression of the CXXC5 in ovarian cancer and the effect of the CXXC5 on ES-2 cell proliferation. Methods:①The alteration of CXXC5 in cancer genomics data of TCGA (Cancer Genome Atlas) was analyzed.②The CXXC5 protein in the tissue chips was detected containing 37 benign ovarian cyst and 173 malignant tumor samples. The relationship between the expression of the CXXC5 with the clinicopathological features of patients with ovarian cancer was analyzed by SPSS software;③The cells with the highest CXXC5 expression quantity from 5 ovarian cancer cells were selected by re-al-time quantitative PCR (qRT-PCR) and Western blot.④ES-2 cells with shRNA stable transfection were construted us-ing the strategy of lentivirus infection and analyzed cell proliferation by cell counting kit-8(CCK8). Results:①Through the TCGA database, CXXC5 ampliifcation was found in 7 of 563 cases.②The CXXC5 expression in ovarian malignant carcinoma (39.3%) was higher than that in benign ovarian cyst (13.5%, P=0.003), the histologic type was highly asso-ciated with CXXC5 (43%in serous, 22.9%in mucinous, 23.5%in endometrioid, 67%in clear cell, P=0.014) and there was a signiifcant correlation between CXXC5 and lymph node metastasis (positive vs negative, P=0.022).③The ES-2 cells with shRNA stable transfection had a growth disadvantage (P<0.05). Conclusion:The CXXC5 gene might have an advantage in proliferation of epithelial ovarian carcinoma and be expected to become the biomarker of poor prognosis.

Objective To establish an animal model of annulus fibrosus (AF) partial defect for the repairing of interver?tebral disc (IVD) defect. Methods Image J 1.46r software was used to measure the T12/L1-L6/S1 intervertebral height in ovine lumbar spine X-ray films. AF thickness was measured by axial split disc. A 11 blade was used to make a trapezoid de?fect of upper bottom 3 mm, lower bottom 5 mm, height 5 mm and thickness 3 mm, whose lower bottom toward the nucleus pulposus (NP) in the left front of ovine lumbar IVD in vitro. The minimally invasive lateral approach was used to make the same type of trapezoid defect in the left front of the ovine lumbar IVD in vivo. The trapezoidal defect length of the axial divid?ing disc was measured, AF and a small amount of NP from trapezoidal defect in IVD were weighed, and the production of trapezoidal defect in IVD was evaluated. Results The lumbar intervertebral space height of ovine was (4.45 ± 0.28) mm. There were significant differences in the thickness of AF (4.08±0.50) mm , thickness (3 mm) and height (5 mm) of trapezoidal defect (P<0.05), respectively. There were no significant differences in trapezoidal defects in ovine lumbar IVD in vitro on the upper bottom (3.03 ± 0.09)mm, the lower bottom (5.03 ± 0.09) mm, the height (4.97 ± 0.10) mm, the thickness(3.02 ± 0.06) mm and the trapezoidal defect predetermined value on the upper bottom 3 mm, the lower bottom 5 mm, the height 5 mm and the thickness 3 mm (P>0. 05). The weights of the AF and NP taken out from ovine lumbar IVD in vitro and in vivo were (0.162 ± 0.011) g and (0.166 ± 0.014) g, and there was no significant difference between them (P > 0.05). Conclusion Through the operation of minimally invasive lateral approach, the method of making a trapezoidal defect in the experiments can establish animal model of AF partial defect, which meets the requirements for the repairing of IVD defect, and is simple, safe and reliable.

Objective To introduce a novel technique of intracolonic shunt procedure used in the anus - preserving operation for acute intestinal obstruction resulted from cancer at low and middle portions of rectum and assess the clinical significance. Methods In total, 81 patients with acute obstruction of low and middle portion of rectum caused by cancer were randomly ( random number) divided into control group and study group. In control group, 42 patients were operated with preventive transverse colonostomy or terminal ileum stoma after low proximal resection of rectum involved in cancer, while 39 patients were operated with intracolonic shunt procedure by using a biodegradable anastomosis ring and a condom placed 5 cm above anastomosis for protection in study group. Results There were no significant differences in sex, age, tumor site, tumor size and the distance from anstomosis to anal-edge between two groups. In both groups, the bowel movement resumed in 2 ~ 5 days after operation (P > 0.05). In study group, the rate of anastomosis leakage was 7.7% (3/39), and leakages were treated with drainage for 7.1 days in average to be healed, and the biodegradable anastomosis ring detached and were discharged in 14 -23 days (17 days in average), and there were no complications of drainage happened. The anastomotic stenosis occurred in three patients (7. 7% ) within 6 months after operation. In control group, 11.9% patients (5/42) had anastomosis leakage and they treated with drainage for 18.2 days in average to get the leakage healed, and 35. 7% patients (15/42) had stoma complications, and anastomotic stenosis happened in 28.6% patients (12/42) within 6 months after operation, and 7. 1% patients need another operation because of severe anastomosis stenosis. There were no significant differences in rate of anastomosis leakage between tow groups ( P > 0. 05), but there were significant differences in drainage days after anstomosis leakage happened and 6 - months anastomosis stenosis between two groups (P<0.05). Conclusions In the anus -preserving operation for acute intestinal obstruction at low and middle portions of rectum caused by cancer , the intracolonic shunt procedure is convenient and safty, and reduces the hazard incurred by anastomosis leakage and anastomosis stenosis compared with classic stoma operation.
