Objective To explore the expression of annexin A10 (ANXA10) in human hepatocellular carcinoma (HCC),and analyze its correlation with matrix metalloproteinases-9 (MMP-9) and vascular endothelial growth factor (VEGF),thus to provide the basis for clinical diagnosis and assessment of HCC.Methods 88 HCC patients were selected,and they were all performed surgical treatment,HCC stage Ⅰ in 11 cases,stage Ⅱ 25 cases,stage Ⅲ 31 cases,stage ⅣV 21 cases.The expressions of ANXA10,MMP-9,VEGF of HCC cancer tissues,adjacent liver tissues and normal liver tissues were tested by immunohistochemical method.The correlation of ANXA10 with VEGF and MMP-9 was analyzed.Results The absorbance value of ANXA10 expression in the HCC cancer tissue was (0.074 ± 0.012),which was lower than that in the adjacent liver tissues [(0.091 ± 0.013)] and normal liver tissues[(0.131 ±0.025)],and ANXA10 expression of the adjacent liver tissue was lower than that of the normal liver tissues,the differences were statistically significant (t =8.96,9.44,8.71,all P ＜ 0.05).The absorbance values of MMP-9 and VEGF expression in the HCC cancer tissue were (0.147 ± 0.017) and (0.127 ± 0.028),respectively,which were higher than those in the adjacent liver tissues [(0.096 ± 0.012),(0.091 ± 0.015)] and normal liver tissues [(0.075 ± 0.014),(0.077 ± 0.019)].The absorbance values of MMP-9 and VEGF of the adjacent liver tissues were higher than those of the normal liver tissues,the differences were statistically significant (t =8.05,9.30,8.11;8.28,9.51,8.02,all P ＜ 0.05).The absorbance value of ANXA 10 expression in the HCC stage Ⅲ + Ⅳ cancer tissue was (0.056 ± 0.010),which was lower than that in the stage Ⅰ + Ⅱ cancer tissue [(0.082 ±0.016)],the difference was statistically significant (t =8.90,P ＜ 0.05).The absorbance values of MMP-9 and VEGF expression in the stage Ⅲ + Ⅳ cancer tissue were (0.157 ± 0.022) and (0.169 ± 0.033),respectively,which were higher than those in the stage Ⅰ + Ⅱ cancer tissue [(0.114 ±0.015),(0.091 ±0.021)],the differences were statistically significant (t =9.13,9.72,all P ＜ 0.05).ANXA10 was correlated with MMP-9 and VEGF (r =0.324,0.295,all P ＜ 0.05).Conclusion ANXA10 presents lower expression in HCC cell,and the expression decreased with the increase of staging.It is negatively related with the MMP-9 and VEGF.ANXA10 expression missing or inactivation of malignant change may be one of the most important features in HCC.

Objective To evaluate the effects of early tracheostomy and late tracheostomy on the prognosis of patients with cervical spinal cord injury,so as to provide evidence based guidance for the timing of tracheostomy.Methods Relevant literatures studying the timing of tracheostomy in patients with cervical spinal cord injury were searched in PubMed,Embase,Medline,Cochrane Library,Chinese Biological Medical Literature database (CBM),China National Knowledge Infrastructure database (CNKI),and VIP journal database with time range from journal establishment to March 2018.The retrieved articles were screened according to the inclusion and exclusion criteria.The article quality was rigorously evaluated according to the Newcastle-Ottawa scale (NOS).Meta analysis was conducted using Review Manager 5.3 software to compare the mechanical ventilation time,ICU stay,incidence of pneumonia,incidence of complications,and mortality between early and late tracheostomy in patients with cervical spinal cord injury.Results A total of eight articles of cohort study including 466 patients were included,with 241 patients in the early tracheostomy group and 225 patients in the late tracheostomy group.The eight articles were all determined as high quality studies according NOS.The results of Meta analysis showed that there were significant differences between the two groups in terms of the total mechanical ventilation time (MD =-12.28,95％ CI-20.09--4.47,P ＜ 0.01),post tracheostomy mechanical ventilation time (MD =-9.92,95％ CI-14.27--5.57,P ＜ 0.01),total ICU stay (MD =-10.30,95％ CI-17.12--3.47,P ＜ 0.01),post tracheostomy ICU stay (MD =-5.79,95％ CI -6.53--5.05,P ＜ 0.01),incidence of complications (RR =0.56,95％ CI 0.38-0.83,P ＜ 0.01),and mortality (RR =0.34,95％ CI 0.15-0.78,P ＜ 0.05).However,no significant differences were detected between the two groups in the incidence of total pneumonia (RR =0.77,95％ CI 0.57-1.05,P ＞0.05) and the incidence of post tracheostomy pneumonia (RR =0.80,95％ CI 0.51-1.26,P ＞0.05).Conclusion Early tracheostomy can shorten the mechanical ventilation time,ICU stay,incidence of complications,and mortality,but it cannot reduce the incidence of pneumonia.

Objective To explore the serum levels of VILIP-1 and Cav-1 in cases with severe craniocerebral injury undergoing decompression and their effects on the prognosis.Methods 108 patients with severe craniocerebral injury who were treated in our hospital from July 2019 to July 2022 were selected as the study group,and 120 healthy people who came to our hospital for physical examination were selected as the health group.All cases were followed up for 6 months,and were divided into good prognosis group(GOS=4-5 points,n=82)and poor prognosis group(GOS=1-3 points,n=26)according to GOS.The levels of serum VILIP-1 and Cav-1 were detected by ELISA.The diagnostic value of serum VILIP-1 and Cav-1 on the prognosis of patients was evaluated by the ROC curve.Multivariate logistic regression analysis was used to explore the prognostic factors of patients.Results The levels of serum VILIP-1 and Cav-1 in study group were higher than those in healthy group(P＜0.05).The levels of serum VILIP-1 and Cav-1 in case with poor prognosis were higher than those in cases with good prognosis(P＜0.05).The AUC(95％CI)of serum VILIP-1 and Cav-1 to predict the prognosis of patients was 0.848(0.797～0.899)and 0.817(0.766～0.868).The AUC(95％CI)of the combined detection was 0.905(0.854～0.956).The time from injury to admission,admission GCS score,history of diabetes,admission pupillary reaction,preoperative brain midline displacement and postoperative complications in good prognosis group were different from those in poor prognosis group(P＜0.05).Preoperative midline displacement≥5 mm(OR=2.467,95％CI:1.619～3.760),postoperative complications≥ 2(OR=2.321,95％CI:1.544～3.489),VILIP-1≥10.37 ng/ml(OR=3.367,95％CI:2.087～5.432),and Cav-1≥32.28 μg/L(OR=2.770,95％CI:1.786～4.298)were risk factors for prognosis in patients(P＜0.05).Conclusion Serum VILIP-1 and Cav-1 can be used as biological indicators to predict the prognosis of patients with severe brain injury after decompression,and the increase of serum VILIP-1 and Cav-1 levels are risk factors for prognosis.

Objective To compare the surgical effects between minimally invasive anterior ondontoid screw fixation assisted by our self-designed odontoid guider and open anterior ondontoid screw fixation in the treatment of odontoid fractures of Anderson-D'Alonzo type Ⅱ.Methods From July 2011 to July 2016,28 adults with odontoid fracture of Anderson-D'Alonzo type Ⅱ were treated at Department Ⅱ of Spinal Surgery,Hospital of 89 Army Group of Chinese PLA.Of them,15 were treated by minimally invasive anterior ondontoid screw fixation assisted by our self-designed odontoid guider (guider group) while the other 13 by open anterior ondontoid screw fixation (open group).All the patients were male,aged from 31 to 59 years (average,42.7 years).The 2 groups were compared in terms of incision length,operation time,intraoperative bleeding,intraoperative fluoroscopic frequency and hospital stay.Results There were no significant differences between the 2 groups of patients in their preoperative general data,indicating they were compatible (P ＞ 0.05).All the patients were followed up for 12 to 45 months (average,22.1 months).The internal fixation was in good place and clinical union achieved in all the 28 patients.The incision length (2.2 ± 0.1 cm),operation time (45.0 ± 3.1 min),intraoperative bleeding (29.0 ± 2.3 mL) and intraoperative fluoroscopic frequency (15.5 ± 1.9 times) for the guider group were all significantly less than those (2.9 ±0.7 cm,61.6±3.8 min,51.6±3.9 mL and 21.7±3.2 times,respectively) for the open group (P ＜0.05),but there was no significant difference between the 2 groups in hospital stay (6.5 ± 0.5 d versus 6.5 ± 0.6 d) (P ＞ 0.05).Conclusion In the treatment of odontoid fractures of Anderson-D'Alonzo type Ⅱ,compared with open anterior ondontoid screw fixation,the minimally invasive anterior ondontoid screw fixation assisted by our self-designed odontoid guider may lead to a smaller incision,shorter operation time,less blood loss and a lower fluoroscopic frequency.

Epilepsy is a common disease in central nervous system;most patients with epilepsy after regular anti-epilepsy drug treatment can be controlled,but drug treatment in about 20％-30％ of patients is invalid,known as refractory epilepsy.With the development of imaging techniques,PET/MRI emerge and they combine anatomical and functional imaging,which makes the imaging more clear,enjoying more accurate anatomical structure.Thus,PET/MRIplay important roles in the process of pathogenesis,diagnosis and preoperative assessment of epilepsy.We mainly introduce the concepts of PET/MRIand the comparison with other imaging technology,and describe the application of PET/MRI in preoperative assessment ofrefractory epilepsy.
