1.The radiation dose and protection during percutaneous vertebral augmentation
Chinese Journal of Tissue Engineering Research 2015;19(21):3409-3413
BACKGROUND:A large number of literatures have shown that surgeons expose to a higher radiation dose during puncture and bone cement injection in percutaneous vertebral augmentation. OBJECTIVE:To review the research progress in radiation doses and safeguard procedures in percutaneous vertebral augmentation. METHODS: By using percutaneous vertebral augmentation, radiation doses, radiation protective as key words, we retrieved articles related to radiological protection during percutaneous vertebral augmentation published from January 1995 to December 2014 in Wangfang database and PubMed database. RESULTS AND CONCLUSION:One basic principle of radiation protection is that the radiation dose decreases rapidly with distance from the radioactive sources. Surgeons should maximize the distance from the radioactive sources as far as possible in case there is no effect on the operation. To optimize the setting and position of C-arm machine, wear protective devices and put lead shields as wel as computer navigation and radiation training in surgeons al can help to reduce the radiation doses during percutaneous vertebral augmentation. Remote bone cement injection device is easy to control but not increases the radiation doses. In addition, the influence of surgery bed on radiation dose remains to be further studied. We believe that with the in-depth research on radiological protection, vertebral augmentation technique wil be safer in clinical application.

Journal of Clinical Hepatology 2014;31(5):417-420
Objective To investigate the clinical value of serum soluble intercellular adhesion molecule-1 (sICAM-1 )in patients with primary biliary cirrhosis (PBC)and autoimmune hepatitis (AIH).Methods Sixty-one PBC patients and 59 AIH patients,who were hos-pitalized or visited the outpatient department from June 2012 to September 2013,as well as 50 healthy controls,were included in the study. The PBC patients included 29 incipient cases,21 cases in remission,and 11 recurrent cases;the AIH patients included 26 incipient cases, 20 cases in remission,and 13 recurrent cases.Serum sICAM-1 level was measured by double-antibody sandwich enzyme-linked immu-nosorbent assay,and serum levels of alanine aminotransferase (ALT)and total bilirubin (TBil)were determined by biochemical enzyme as-say.Comparison between groups was made by analysis of variance;Pearson correlation analysis was performed.Results Among PBC pa-tients,the incipient group and recurrent group had significantly higher serum sICAM-1 levels than the remission group and control group (P=0.000 for all);there was no significant difference in serum sICAM-1 level between the incipient group and recurrent group (P=0.484);the remission group had a significantly higher serum sICAM-1 level than the control group (P=0.000).Among AIH patients, the incipient group and recurrent group had significantly higher serum sICAM-1 levels than the remission group and control group (P=0.000 for all);there was no significant difference in serum sICAM-1 level between the incipient group and recurrent group (P=0.802);no significant difference in serum sICAM-1 level was seen between the remission group and control group (P=0.281).For patients with PBC and AIH,serum sICAM-1 level was positively correlated with serum levels of ALT (r=0.664,P=0.000;r=0.784,P=0.000) and TBil (r=0.715,P=0.000;r=0.580,P=0.000).Conclusion Serum sICAM-1 may be involved in the immunologic injury in PBC and AIH.In patients with PBC and AIH,the elevation of serum sICAM-1 level is closely correlated with the severity of liver damage. Clinical monitoring of serum sICAM-1 level may play an important role in severity assessment,prognostic evaluation,and therapy guidance among patients with autoimmune liver diseases.

Objective Reviewing the experience in the diagnosis and treatment of cases with aorta-pulmonary septal defect and aortic origin of right pulmonary artery complicated with interruption of the aortic arch. Methods Reviewed clinical data from medical records for5 patients (4 boys and 1 girl, age from 1 to 18 years on admission) who had been treated in Wuhan Asia Heart Hospital between 2005 and 2009. Results All cases had type A interruption of the aortic arch ( according to Celoria and Patron's Classification) , type Ⅱ aorta-pulmonary septal defect( according to Mori Classification) and aortic origin of right pulmonary artery complicated with interruption of the aortic arch. Large patent ductus arteries were observed in all cases,and no cardiac abnormality such as ventricular septal defect was found. All patients received echocardiography and spiral CT examination, and 3 of them over 10 years of age received cardiac catheterization and angiography for the evaluation of the pulmonary artery pressure. Two patients, at the age of 14 and 18 years, had severe pulmonary hypertension and declined to receive the operation. One of the 2 cases had hemoptysis and was given prostacyclin ( Iloprost solution for inhalation, a drug for pulmonary artery hypertention ) for reducing the pulmonary pressure. The patient now has an improved cardiac fu0ction without recurrent hemoptysis. One 14-year-old case gave up the operation because of the financial problem and failed to communicate with us after discharge. Radical surgery was performed in the remaining three cases, one had serious infection in the lung and died 11 days after the operation, in one case ( 2 years old) pulmonary artery hypertension has been persisted even though drug therapy was given for a long time and was found at a poor cardiac function 18 months after the operation. One patient recovered well under routine drug therapy and has been followed-up. Conclusion Aorta-pulmonary septal defect and aortic origin of right pulmonary artery with interruption of the aortic arch ( with intact ventricular septum) are different from the classic triad of inter ruption of the aortic arch, consisted of the interruption of the aortic arch, patent ductts arteriosus and ventricular septal defect.It should be considered as a special kind of cardiovascular malformation syndrome. Echocardiography can be used for the preliminary diagnosis of aorta-pulmonary septal defect and aortic origin of right pulmonary artery with interruption of the aortic arch. The final diagnosis and decision for surgery should be based on the combined information from cardiac catheterization,cardiovascular angiography and spiral CT examination. Pulmonary artery pressure and resistance are the most important factors,because they have great effects on the duration of surgery and the outcome. A radical operation is necessary for all cases, but the mortality rate is high. The prognosis would be great if only the patient can survive successfully during the peri-operative period, a period with a poor cardiac function, potential lung infection and the pulmonary artery hypertension.

Objective: To observe the clinical efficacy of combined needle-embedding and SSRIs for depressive sleep disorder. Method: Upon admission, 71 depression cases were randomized into needle-embedding group of 24 cases, using combined needle-embedding and SSRIs, acupuncture group of 21 cases, using combined acupuncture and SSRIs, and medication group of 26 cases, using SSRIs alone. After 1, 2, 4 and 6 weeks of treatment, the HAMD sleep scores were compared. Result: The HAMD sleep scores in the needle-embedding and acupuncture group were remarkably superior to the medication group and there was significant statistical difference after 1, 2 and 4 weeks of treatment (P<0.01). However, there was no statistical difference after 6 weeks of treatment. Conclusion: SSRIs can improve HAMD sleep scores. The combined needle-embedding or acupuncture with SSRIs can work faster and better than medication alone. There was no statistical difference between needle-embedding and acupuncture group, however, needle-embedding can reduce the treatment frequencies and therefore has more active clinical meaning.

Background The treatment timing and method of amblyopia rely on the plasticity of visual system.Synapsin is a family of presynaptic terminal specific protein.Its role in visual developmental plasticity is below understood.Objective To investigate the dynamic expressions of synapsin (T-synapsin),and phosphorylation of synapsin (p-synapsin Ⅰ a/b) in visual cortex of normal mice and further explore the role of synapsin in plasticity of visual system.Methods Forty-two clean neonatal C57BL/6 mice were collected.The mice were sacrificed at postnatal 7,14,21,28,35,42,60 days respectively to obtain the tissue samples of visual cortex.Expression levels of T-synapsin and p-synapsin in the visual cortex following the ageing were quantitatively detected using Western blot assay.Results The expression of synapsin in normal mice showed a dynamic increase with the ageing.The T-synapsin Ⅰ a/b/β-actin value in visual cortex was (21.32 ± 3.27) %,(56.27 ± 10.18) %,(77.05 ± 10.05) %,(83.75±10.52) %,(94.69±11.46)%,(98.75±5.86) % of adults mice (postnatal 60 days,P60) in the mice of postnatal 7,14,21,28,35,42 days,respectively,showing a significant difference among them (F =69.538,P < 0.001).Compared with the adult mice,the T-synapsin Ⅰ a/b/β-actin value in the mice of P7,P14,P21,P28 was significantly lower (all at P<0.05),but no significant difference was found between P35 and P60,P42 and P60 (P =0.280,0.798).The development trend of different synapsin subtypes,such as T-synapsin Ⅰ a/b,T-synapsin Ⅱ a,T-synapsin Ⅱ b and T-synapsin Ⅲ a,was not quite the same during the ageing.The expression of T-synapsin Ⅱ a and Ⅲ a increasing more slowly with development,and kept increasing until P60.Significant differences were found among various age of mice in T-synapsin Ⅱ a,Ⅱ b,Ⅲa respectively(F =42.492 55.595,39.172,all at P<0.001).The p-synapsin Ⅰ a/b level in the visual cortex elevated with the ageing of the mice,and that peaked in P21 mice,which was (2.86±0.17) times more than that in adult mice.After that,the expression level of p-synapsin Ⅰ a/b dropped rapidly.A significant difference was found in the p-synapsin Ⅰ a/b expression among different ages of mice (F =22.620,P < 0.001).Conclusions Synapsin level in visual cortex presents a developmental change which correlated with the onset and decline of the critical period.Synapsin is probably involved in the regulation of neural plasticity in visual cortex in critical period.
