BACKGROUND: The injury of peripheral nerve may cause electroneurographic changes. However, what is the correlation between electroneurographic changes and the extent of nerve injury?OBJECTIVE: To probe into the changes of evoked electroneurography in early stage after nerve injury for clinical application and reference.DESIGN: Paired t-test in three groups of samples.SETTING: Department of Traumatic Orthopaedics People' s Hospital of Beijing University.MATERIALS:The trial was conducted in the Animal Center of the People's Hospital of Beijing University from August 2003 to December 2003. The subjects were 8 adult New Zealand rabbits of SPF grade(weighing 1.5 kg) and either gender from the Animal Center of Medical College of Beijing University.METHODS:The model of nerve injury was made in the 16 tibial nerves of the 8 rabbits, in which one third or two thirds of each nerve was ligated at the same transverse part. The samples were thus divided into three groups: non-injury (normal) group, 1/3 nerve injury group and 2/3 nerve injury group.MAIN OUTCOME MEASURES: The indices of evoked electroneurography, i. e. motor nerve condution velocity, negative M wave amplitude, negative M wave area, maximal M wave amplitude and maximal M wave area were measured in the three groups. The correlation between the extent of nerve injury and the 5 indices was analyzed.RESULTS: All the 5 indices of the 3 groups were significantly different( P＜ 0.05). The mean values of the 5 indices were 1.00 ±0.0,0.97 ±0.18,1.01 ±0.22;0.98 ±0.16 and 0.98 ±0.19 in normal group, 0.76 ±0.12,0.41 ± 0.24, 0.47 ± 0.30, 0.48 ± 0.27 and 0.50 ± 0.29 in 1/3 nerve injury group, and 0. 62±0. 10, 0. 11 ±0. 11, 0. 11 ±0. 10, 0. 12 ±0. 14 and 0.13± 0. 12 in 2/3 nerve injury group. The coefficient of correlation between the 5 indices and the injury were 0. 902, 0. 938, 0. 936, 0. 907, and 0. 914, respectively.CONCLUSION: In the early stage after peripheral nerve injury, the electroneurographic indices negatively correlate with the extent of nerve injury. The negative M wave amplitude and area are relatively more closely correlated with the extent of injury.

Objective To evaluate the feasibility and clinical effect of stage Ⅰ posterior vertebral corpectomy filled with titanium mesh cages plus long-segmental instrumentation for treatment of Denis type D and E severe unstable thoracolumbar burst fracture.Methods A retrospectively review was made on 14 patients with Denis type D and E severe unstable thoracolumbar burst fracture,having had posterior vertebral corpectomy,titanium mesh bone grafting and long-segmental pedicle screw fixation.Parameters recorded were operation time,amount of bleeding,bone fusion and reduction,postoperative complications,low back pain,neurological performance,restoration and loss of anterior vertebral height,correction and loss of kyphosis,and intraspinal space occupying lesion.Results Mean operation time was 207.1 min (range,148-306 min) and blood loss was 585 ml (range,300-1,500 ml).Intraoperative fracture reduction was satisfactory.Follow-up ranged from 18 to 54 months (mean,28 months),which showed no complications of infection,screw-rod breakage,loosening or shifting of the internal fixation device,titanium mesh subsidence and pseudarthrosis,and no signs of adjacent segment degeneration.Six months after operation,CT scan showed bony fusion of the bone-implant interface.At the final follow-up,the Denis pain scale improved significantly including 12 patients with completely relieve of pain (P1) and 2 ache slightly but no need of taking painkiller (P2).Neurological functions were improved by 1-3 degree in all patients.Percentage of anterior vertebral height was (41.2 ± 8.9)％ before operation,significantly reduced to (8.3 ± 4.8) ％ one week after operation and to (8.9 ± 5.1) ％ at the final follow-up (P ＜0.01).Mean loss of anterior vertebral height was 0.6％.Sagittal kyphotic angle was (36.9 ± 4.9) °before operation,significantly reduced to (8.1 ± 3.4) ° one week after operation and (8.5 ± 3.8) °at the final follow-up (P ＜0.01).Mean loss of kyphotic angle was 0.9°.Ratio of intraspinal space occupancy was (74.9 ± 11.3) ％ before operation but recovered to (4.1 ± 1.6) ％ one week after operation and (1.8 ± 1.4) ％ at the final follow-up,with significant differences in pair comparison (P ＜ 0.01).Conclusion The use of posterior vertebral corpectomy and fusion with titanium mesh cage fusion in conjunction with long-segment instrumentation are effective for spinal canal decompression,fracture reduction,three-column reconstruction as well as rigid fusion at one stage,lumbar pain relief,neurological function recovery,prevention of correction loss and vertebral height restoration.

Objective: To evaluate the relevance of diabetes mellitus and hepatitis B virus(HBV) infection in people by Meta-analysis. Methods: Databases we searched included CNKI, VIP China Science and Technology Journal Database, Wanfang Data Knowledge Service Platform, PubMed, Cochrane Library and Web of Science Core Collection database. Publication time was from January 1997 to May 2017. The Languages were limited to Chinese and English. English search terms include: diabetes, diabetes mellitus, hepatitis B and risk. Chinese search terms include: diabetes mellitus, hepatitis B and risk. We included all observational studies on diabetes and HBV infection. Firstly, the Newcastle-Ottawa Scale and the evaluation criteria of Cross-sectional study recommended by Agency for Healthcare Research and Quality were used to evaluate the quality of articles. Secondly, RevMan 5.3 software was used for heterogeneity testing. Subgroup analysis, random effects model and Mantel-Haenszel method were used to calculate the combined OR value. Finally, Stata 14.0 software was used to conduct the sensitivity analysis, and Begg rank correlation method was used to detect the publication bias. Results: A total of 12 studies were included, comprising 6 cross-sectional studies and 6 case-control studies. But the 12 articles were heterogeneous (χ²=42.10, P<0.001). After subgroup analysis, cross-sectional studies of diabetes and HBV infection were still heterogeneous (χ²=28.21, P<0.001), whose combined odds ratio (OR) was 1.36 (95%CI: 1.03-1.80). But the heterogeneity of case-control studies was not statistically significant (χ²=10.32, P=0.070), whose combined odds ratio (OR) was 1.55 (95%CI: 1.10-2.17). After the sensitivity analysis, the 95%CI of the combined OR of the 7 studies did not fluctuate, and the lower limit was above 1.07. No publication bias was detected in the cross-sectional study subgroup (Z=1.35, P=0.176) and the case-control study subgroup (Z=1.69, P=0.091). Conclusion Patients with diabetes are more likely to be infected with HBV than those without diabetes. Diabetes mellitus is likely to be a risk factor for HBV infection.

Objective To assess the therapeutic efficacy of a recombined adenovirus expressing p53 (rAd-p53) via intrapleural injec-tion in the treatment of lung cancer with malignant pleural effusion. Methods Thirty-six cases with lung cancer and malignant pleural effu-sion were randomly divided into two groups,which were given intravenous injection of Nedaplatin with (observation group,n=20) or without (control group,n=16) intrapleural injection of rAd-p53,respectively. Between the two groups,the efficacy in treatment of pleural effusion, the amelioration of maximal ventilatory volume ( MVV) ,Kamofsky scoring ( KPS) and quality of life were compared. Results The efficacy in treatment of pleural effusion in observation group are significantly higher than that in control group(17/20 vs. 50%,P<0. 05). The cases with KPS≥80 in observation group were significantly increased following treatment (5/20 vs. 11/20,P <0. 05). However,there was no difference with the cases in control group. Conclusion Intrapleural injection of recombinant adenovirus expressing p53 (rAd-p53) is effec-tive to reduce the occurrence of malignant pleural effusion and increase the quality of life remarkably.

Objective:To evaluate the reliability and validity of Chinese version of Glasgow antipsychotics side-effect scale (GASS).Methods:Totally 200 patients diagnosed as schizophrenia following the criteria of DSM-IV were enrolled in the study.Cronbach’s α was used to investigate the internal consistency of GASS.Exploring factor analysis was used to examine the construct validity.Pearson correlation analysis between GASS and TESS and CGI sub-scale of side effect were conducted to evaluate the criterion validity.Based on clinical criteria, the sensitivity and specificity and ROC curve was calculated so as to establish the cut-off point of the scale and test discrimination validity.Results:For reliability, Cronbach’s α ws 0.926, indicating that GASS had a good internal consistency.Four main factors were extracted by exploratory factor analysis which were extrapyramidal side effect factor, genitourinary side effect factor, anticholinergic side effect factor, over sedation and cardiovascular side effect factor.For validity, exploring analysis demonstrated that nineteen item of the scale has relatively higher factor load on the principal factor (0.531-0.972), suggesting that the scale had a good construct validity.The total score of the GASS was positively correlated with that of TESS and CGI subscale of side effects( r=0.90, P<0.05; r=0.87, P<0.05). The cut-off point of experimental validity of GASS for mild antipsychotics side effects was determined as ≥1.With this cut-off point, GASS had both high sensitivity (96.3%) and high specificity (70.7%), area under curve (AUC) were 0.78.The cut-off point of GASS for moderate antipsychotics side effects was determined as ≥20, with the sensitivity and specificity of GASS were 86.3% and 84.7%, AUC were 0.92.When the cut-off point of GASS for severe antipsychotics side effects was determined as ≥41, GASS had both high sensitivity (92.1 %) and high specificity (96.3 %), AUC were 0.96. Conclusion:GASS has good reliability and validity and can reflect the side effects of antipsychotics, and it can be adopted as a useful instrument to evaluate the severity of side effects of antipsychotics.

Objective:To explore the efficacy and safety of FOLFOX4 regimen hepatic arterial infusion chemotherapy (HAIC) combined with 125I seed implantation or gamma knife in patients with primary liver cancer and type Ⅲ portal vein tumor thrombosis (PVTT). Methods:The clinical data of 116 patients with primary liver cancer and type Ⅲ PVTT from January 2016 to June 2018 in the Sixth Medical Center of PLA General Hospital were retrospectively analyzed.
