Conclusion The lower expression of EPOR was observed in ovarian epithelial tumor cell. Use rHuEPO couldn't promote the cancer's progression and bring negative effect in clinical practice. Further clinical research is required to prove it.

Objective To investigate the clinical efficacy,operative essentials and indications of hybrid spinal fusion surgery for cervical spondylotic myelopathy.Methods From August 2008 to December 2011,thirty-eight patients with cervical spondylotic myelopathy underwent hybrid spinal fusion surgery in our hospital.There were 27 males and 11 females,aged from 33 to 70 years (average,51 years).A total of 86 segments were treated (fusion 48 vs.non-fusion 38).Twenty-eight patients underwent a two-level surgery,and ten patients received a three-level surgery.The Japanese Orthopaedic Association (JOA) score and Visual analogue scale (VAS) were used to evaluate pre-and post-operative neurological function and pain,respectively.The pre-and post-operative range of motion of the cervical spine was measured according to Xrays.Moreover,the surgical complications were recorded and analyzed.Results Thirty-seven patients were followed up for 15 to 55 months (average,29.1 months).The improvement of neurological function was obtained in 36 patients.The JOA score was improved from preoperative 10.5±1.57 to 14.3±1.97 at final follow-up,with an improvement rate of 58.46％,and the results were excellent in 16 cases,fair in 20 cases and poor in 1 case.The VAS was improved from preoperative 7.3±1.04 to 3.2±1.41 at final follow-up.The Cobb angle changed from preoperative 25°±3.21°to 20°±2.56°at final follow-up.After operation,the neurological function was not restored in 1 case; hoarseness and bucking occurred in 2 cases; sore throat occurred in 22 cases; anterior displacement of prosthesis (PCM) occurred in 3 cases.Other patients had no complications,such as displacement,loosening and heterotopic ossification.Conclusion In hybrid spinal fusion surgery,the lesions segments are decompressed fully,the severely degenerative segments are fused,and the motion of the non-fusion segments is reserved.As a result,not only the stability of the cervical spine is achieved,but also an obvious improvement of symptoms and a satisfactory short-term efficacy can be obtained.Therefore,this method is an alternative procedure for cervical spondylosis myelopathy.

Objective To explore the clinical characteristics of liver cirrhosis patients complicated with ischemic hepatitis . Methods The clinical data were reviewed retrospectively for 30 cirrhosis patients complicated with ischemic hepatitis from January 2008 to June 2013 in the intensive care unit of Dalian Sixth People′s Hospital .Results Ischemic hepatitis was identified in 1 .6% of the patients treated at the same period in ICU .In addition to the underlying disease including cirrhosis ,the patients also showed hypovolemic shock ,severe sepsis ,acute attack of chronic heart failure and acute respiratory distress syndrome . Acute increase of serum alanine aminotransferase(ALT) and aspartate aminotransferase(AST) was also reported in association with significant decrease of albumin .The patients were treated with comprehensive measures targeting shock ,infection ,heart failure ,respiratory failure ,and relevant symptoms .The overall mortality was 66 .7% (20/30) .The mortality was significantly higher in Child‐Pugh C cirrhotic patients than Child‐Pugh A or B patients .Conclusions The ischemic hepatitis in association with liver cirrhosis is mainly induced by hypovolemic shock ,severe sepsis ,heart failure ,and respiratory failure .Typical laboratory findings are sharp elevation of serum ALT and normalization after treatment . Liver cirrhosis complicated with ischemic hepatitis features high mortality ,particularly in Child‐Pugh C cirrhosis .

Retinal pigment epithelium ( RPE ) is a vital tissue for the maintenance of photoreceptor function and environment of outer retina, also the predominant cell type of proliferative vitreoretinopathy ( PVR ) . lt is also affected by many diseases of the retina and choroid, including diabetic retinopathy ( DR) , age-related macular degeneration ( AMD ) and retinal pigmentosa ( RP ) . Although of neural origin, the RPE is capable of local repair, and cells may migrate and take on altered characteristics. These findings indicate that RPE-based therapy is a promising option for congenital or degenerate disease of the retina.

Objective To investigate the distribution modes of NOS nerves and interstitial cells of Cajal (ICCs) in myenteric plexus of human fetal intestine. Methods Small intestine samples from 12 fetuses were collected for the preparation of whole mount preparations and cryo sections examined by immunocytochemistry for c kit receptor tyrosine kinase and histochemistry for NADPH diaphorase. Results ICCs associated with the myenteric plexus in the fetal small intestine were observed in the shape of spindle or ovoid with two to three slender processes forming an independent and complete cellular network. While NOS positive nerves, which constitute the main neuronal component of ganglia, connecting strands, and nerve fibers, were found within the circular muscle layer and myenteric plexus of the small intestine and the latter was especially rich of this kind of nerves. Most of these positive neurons were Dogiel I type neurons and they often gathered in cluster in the ganglia. Each ganglion contained several to dozens of NOS positive neurons. Although no colocalization of ICCs and NOS positive nerves was found by double staining of whole mount preparations and cryo sections, they were closely distributed. Conclusion Our results indicate that NO released by myenteric plexus, an inhibitory neurotransmitter, may possess the function of regulating ICCs and smooth muscle in late stage of the fetus.

Objective To investigate the effect of vascular endothelial growth factor C (VEGF-C) on apoptosis of pancreatic cancer cell. Methods Human pancreatic cancer cell line PANC-1 orthotopic implantation tumor model was established in nude mice. Primary pancreatic cancer cells and that derived from lymphatic metastasis were primarily cultured. Expression of VEGF-C was inhibited through antisense oligodeoxynucleotide in vitro transfection. Reverse transcription polynlerase chain reaction (RT-PCR) and flow cytometer were used to detect the effect of VEGF-C on apoptosis of pancreatic cancer cells and bcl-2. Results After in vitro transfection, mRNA expression level of VEGF-C in PANC-1 pancreatic cancer cells significantly decreased (P ＜0. 01 ). Apoptosis rate of pancreatic cancer cells derived from spontaneous lymphatic metastasis was (2. 83 ± 1.01 ) %, ( 4. 98 ± 2. 05 ) %,and ( 13.22 ±2. 17) % respectively for control group, SODN group and ASODN group after in vitro transfection among which apoptosis rate in ASODN group increased significantly (P ＜0. 01 ). However, apoptosis rate for pancreatic cancer cells derived from primary tumor had no obvious change (P ＞0.05), with (3.51 ±1.38)%, (4.76 ±2. 16 ) %, and (5. 33 ± 2. 18 ) % respectively in control group, SODN group and ASODN group. The expression level of bcl-2 in pancreatic cancer cells derived from spontaneous lymphatic metastasis decreased significantly (P ＜0. 05) while it had no obvious change in primary pancreatic cancer cells (P ＞ 0. 05). Conclusion To inhibit expression of VEGF-C in pancreatic cancer cell can promote apoptosis of pancreatic cancer cell, which is relevant to downregulation of bcl-2;however, it has no obvious effect on primary pancreatic cancer.
