Chinese Journal of Postgraduates of Medicine 2016;39(11):1054-1056
Cervical spinal canal tumors is not rare,accounting for about 15%of all spinal tumors. Due to the particularity of its anatomical location and the severity of operative complications, it is considered as a difficult point in spinal surgery. With the development of imaging medicine and various surgical techniques,many new theories and techniques have been developed. Its overall treatment effect is satisfactory, but the serious surgical complications not rare. This article reviews the progress in treatment of cervical spinal canal tumors, in order to provide a reference for the further improvement of cervical spinal canal tumors treatment .

Objective To study the effect of comprehensive care on the level of high-sensitivity Creactive protein and matrix metaloproteinase-9 in patients with hemorrhagic infarction.Methods 48 patients with hemorrhagic infarction were divided into the control group and the observation group with 24cases in each group.The control group was given conventional care,the observation group was given comprehensive care.Serum hsCRP and MMP-9 level of all patients were measured on day 1,day 3,day 7,day 14.Results The level of serum hsCRP and MMP-9 in the observation group on day 7 was significantly decreased compared with on day 1.The level of serum hsCRP and MMP-9 in the observation group on day 7 was lower than the control group.On day 14,the level of serum hsCRP and MMP-9 returned to normal in the observation group,which was lower than the control group.Conluusions The implementation of comprehensive care for HI patients can effectively reduce the hsCRP and MMP-9 level in serum,shorten hospitalization time,and is conducive to the prognosis of patients.

Objective To investigate the role and value of the biliary stent in the treatment of large common bile duct stones. Methods Thirty-two patients with large common bile duct stones were underwent plastic biliary stenting after endoscopic stone extraction with oddi sphincterotomy, and were followed up for 6 months. Results Thirty-two patients were successfully placed biliary stents. The postoperative jaundice, abdominal pain and other symptoms were alleviated. The secondary endoscopic retragrade cholang iopancreatography (ERCP) was performed six months after surgery. Large stones disappeared in 3 cases, 25 cases were reduced to varying degrees, 4 cases showed no obvious narrowing in 32 patients with biliary stones. Twenty-nine patients with residual stones were taken stone again. The operation was successful in 25 cases . Four cases continued to be observed the drainage of biliary since the difficulties for taking stone. The success rate of treatment of large common bile duct stones by biliary stent was 87.5%. Conclusion The therapy of large common bile duct stones by biliary stent is of simple, short operation time, fewer complications, satisfactory results, safe and effective advantages.

Objective To study the effect of formaldehyde exposure on DNA-protein crosslinks (DPC) in buccal mucosa cells in students who were taking anatomy course.Methods The modified SDS-KCl precipitation assay published by Zhitkovich and Costa in 1992 was applied to detect DNA-protein crosslinks in human cells.And this method has been used to explore DPC induced by different pollutants in numerous studies.37 medical students (20 males and 17 females) aged 19.24?1.09 (mean?standard deviation) and 40 students (20 males and 20 females) in natural science college aged 19.55?0.99 (mean?standard deviation) were studied.The frequency of exposure to formaldehyde was 6 h per week in exposed group.Results Concentrations of formaldehyde in anatomy laboratory ranged from 0.42 to 1.57 mg/m3.Exposure to formaldehyde resulted in an increase of DNA-protein crosslinks.The percentage (mean?standard deviation) of DNA-protein crosslinks in exposed and nonexposed students were 25.72%?6.48% and 22.88%?5.34% respectively(P0.05).Conclusion The result of the present study suggests that formaldehyde exposure in medical students increases the frequency of DNA-protein crosslinks in buccal mucosa cells and females may be more sensitive to formaldehyde exposure.

?AlM:To investigate the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system before and after laser peripheral iridectomy (LPl) in primary angle-closure suspetive (PACS).
? METHODS: Sixty eyes of 33 PACS patients were enrolled in this study. Pentacam examination was performed before and 1d after LPl to measure the central anterior chamber depth ( CACD ) , the peripheral anterior chamber depth ( PACD ) , the anterior chamber volume ( ACV) and the peripheral anterior chamber angle ( ACA) . Statistical analysis used paired t test.
?RESULTS: There was no statistical significance on the changes of ACD. PACD and ACV increased significantly between before and 1d after LPl. ACA was widened from (22. 26o±5. 18o) to (26. 42o±5. 20o), which were increased significantly between before and 1d after LPl.
?CONCLUSlON: LPl can deepen the PACD and increase the ACV in PACS. PACD and ACV are the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system.

Objective To discuss the possibility of differentiation of mesenchymal stem cells(MSCs)from umbilical cord blood(UCB)into hepatocyte-like cells in the in vitro culture.Methods MSCs were isolated from UCB,cultured and passaged.The surface markers were examined by flow cytometry.When cells were cultured to the third passage,they were inoculated into a 6-well plate.A two-stage induction method was used:MSCs in the first phase were cultured in DMEM/F12 medium supplemented with dexamethasone(final concentration of 0.5 μmol/L,the same below),hepatocyte growth factor(HGF,10 ng/ml),epidermal growth factor(10 ng/m1)and 1×insulin-transferrin-Se(ITS)for two weeks,then in DMEM/F12 supplemented with 0.5 μmol/L dexamethasone,10 ng/ml HGF,1×ITS,10 ng/ml Oncostatin M for another two weeks.Morphological changes were observed under a microscope.The gene expression correlated with hepatocytes was detected by using RT-PCR.Immunofluorescence staining was used to identify the expression of specific protein related to hepatocytes(AFP,Albumin,CK-18).Ultrastructure was detected under an electron microscope.Results In the cultured MSCs from UCB,CD34/CD45/CD14,CD54,CD49f and HLA-DR were not detected,there was low expression of CD106 and strong expression of CD29,CD44 and CD13.The gene expression of AFP,albumin,CK-18 and TAT was discovered and three kinds of protein AFP,albumin and CK-18 were positively showed in cytoplasm after 4 weeks'induction.The hepatin granules and fatty drops in cytoplasm of cells induced for 4 weeks were found under an electron microscope.Conclusion The MSCs fromUCB can differentiate into hepatocyte-like ceils in the in vitro culture under some conditions.
