BACKGROUND:Increasing studies have found that, percutaneous vertebroplasty and bone cement are characterized by few traumas, few bleeding, simple operation, rapid recovery, rapid pain relief, and effective efficacy. However, tumor recurrence, symptom improvement, bone cement leakage and other complications make people controversial. OBJECTIVE: To explore and summarize clinical outcomes and safety of percutaneous vertebroplasty and bone cement for treating symptomatic vertebral hemangioma. METHODS:Fifty-two cases patients of symptomatic vertebral hemangioma (including 21 male and 31 female, aged 16-63 years) were treated with percutaneous vertebroplasty and bone cement. The lesions were found at T5-T12 in 36 cases and at L1-L3 RESULTS AND CONCLUSION: Al 52 patients were folowed up for at least 6 months after the operation. The Visual Analogue Scale and Oswestry Disability Index were significantly increased at 1 day, 3 weeks and 6 months post-surgery, when compared to before surgery (P< 0.05); the modified Macnab evaluation was excelent in 40 cases, good in 7 cases, fair in 3 cases, and poor in 2 cases, and the excelent and good rate was 90%. Only one patient had recurrence at 6 months after surgery and one patient had the leakage of bone cement. No other complications were found. Percutaneous vertebroplasty and bone cement could effectively cure vertebral hemangioma and relieve the pain, which is a safe treatment. in 16 cases. Clinical outcomes such as Visual Analogue Scale, Oswestry Disability Index and modified Macnab criteria, as wel as complication before and after surgery were evaluated.

Objeetive To explore routine magnetic resonance imaging characteristics of newborn bilirubin encephalopathy(NBE).Methods MRI features and clinical data of 17 patients with Newbern bilirubin encephalopathy were retrospectively analyzed, globus pallidus (GP)and subthalamic signal intensity was evaluated.The increase of GP signal intensity and serum total bilirubin peak value were analyzed using pearson correlation analysis.Serum total bilimbin peak value between patients with high signal in the subthalamic nuclei on T1 WI and patients without high signal in the subthalamic nuclei were compared statistically.Results The main MRI presentation in the NBE group Was abnormally increased signal intensity in the GP on T1 WI,which was not apparent on T2 WI One patient showed abnormal high signal intensity in the postemmedial part of GP.Nine patients had high signal in the subthalamic nuclei on T1 WI and normal signal on T2 WI Four patients showed hiigh signal in the brainstem with sparing of dorsal pontine.The increase in value of GP signal intensity was 249.0-423.8 in 12 patients and their serum total bilirubin peak values were 366.0-983.3μmol/L A positive correlation Was found between increase of GP signal intensity and serum total bilirubin peak value.The serum total bilirubin level of abnormal subthalamic group and normal subthalamic group were 660.7±192.4 μmol/L and 513.3±107.5μmol/L respectively.The difference between the two groups was not statistically significant(t=1.914,P＞0.05).Conclusion The routine MRI has some characteristics and is useful in the diagnosis of newborn bilirubin encephalopathy.

Objective To compare the clinical effect and safety of percutaneous vertebroplasty between unipedicular and bipedicular approach for patients with osteoporosis vertebral compressive fractures. Methods A retrospective study was carried out on 147 patients with single osteoporotic vertebral compressive fractures from 2008 to 2014. Ninety-five cases were treated by PVP via a unipedicular approach (unipedicular group) and 52 cases were treated by the bipedicular approach (bipedicular group). The operation time, Cobb, frequency of X-ray exposure,complications like bone cement and postoperative VAS score were compared. Results No significant differences on the VAS score, cobb and complications were found (P > 0.05). However, there were significant differences on the operation time and X-ray exposure frequency (P<0.05). Conclusions No significant differences on clinical effects were found between the unipedicular and the bipedicular approach to percutaneous vertebroplasty for osteoporosis vertebral compressive fractures. However, the unipedicular approach can shorten the operation time and reduce X-ray exposure.

Objective To observe the efficacy of Mimics finite element analysis software in the gasserian ganglion radiofrequency treatment of trigeminal neuralgia. Methods 180 cases with primary trigeminal neuralgia and VAS score ≥8 were randomly divided into 2 groups (n = 90 each): CT group (group C) and Mimics group (group M). The preoperative skull CT image of the foramen of cranial base could be analyzed in group C. The preoperative cranial CT image could be reconstructed and analyzed by Mimics finite element analysis software in group M. The puncturing success rate, complications rate and the outcomes between two groups were recorded. Results The puncturing success rates were 100% in group M and 92% in group C (P < 0.05). 6 cases with hematoma and 1 case, which were stabbed into the oral cavity were found in group C. No puncture complication was found in group G. There was no statistically significant between the two groups (P < 0.05). The VAS score was 1.6 ± 0.3 in group C and 1.3 ± 0.4 in group G, there was no statistical significance (P > 0.05) between them. Conclusions The Mimics finite element analysis software could improve the success rate of basicranial foramen ovale puncture and reduce the occurrence rate of puncture complications. Therefore , it could be safely applied to the treatment of primary trigeminal neuralgia by gasserian ganglion radio frequency.

Objective To investigate the correlation between plasma soluble CD14 (sCD14)level and disease progression in patients with acute phase of acquired immunodeficiency syndrome (AIDS). Methods Forty-one human immunodeficiency virus (HIV)-infected patients were followed up from June 2007 to June 2010 in Beijing You′an Hospital,including 20 patients with CD4 + T lymphocyte counts more than 350/μL,and 21 less than 350/μL after 3 years of HIV infection.Twenty healthy blood donors were recruited as controls.Enzyme-linked immunosorbent assay (ELISA)was employed to test the plasma sCD14 level of healthy controls and patients infected with HIV at 1 -30 d,31 -90 d,91 - 180 d and 181 -360 d.Student t test was used to compare the means between two groups.ANOVA analysis was used to compare the means among more than two groups.Results The mean plasma sCD14 level in control group was (1 654±904)μg/L.Three years after HIV infection,the sCD14 level of patients with CD4 + T lymphocyte counts less than 350/μL group was (4 214±2 635)μg/L,which was higher than that of patients with CD4 + T lymphocyte counts more than 350/μL ([2 275 ±1 457 ]μg/L).The difference was statistically significant(t=-5 .41 ,P <0.01).The plasma sCD14 level in patients infected with HIV 181 -360 d was significantly higher than that in patients infected with HIV 1 - 30 days ([4 485 ± 2 779]μg/L vs [2 577 ±1 635 ]μg/L;t = -3.39,P <0.05 ).The plasma sCD14 level was positively correlated with HIV viral load (r =0.35,P =0.000 1 ),and negatively correlated with CD4 + T lymphocyte counts (r=-0.28,P =0.001 ).Conclusions The plasma sCD14 level in patients with acute phase of HIV infection is higher than that of healthy people,which increases with prolonged HIV infection.Plasma sCD14 level in of HIV infection acute phase may be closely related to HIV/AIDS progression.
