Angiography technique is one of the most important technique in the diagnosis of vascular diseases,espcially in the diagnosis and treatment of intracranial aneurysms,coronary arterial and extremity arterial diseases.Preliminary application of angiography has been carried out on the diagnosis and pre-operative evaluation of some kinds of tumors such as musculoskeletal tumors.In this review,current clinical application and progress,advantages and disadvantages of digital subtraction angiography,computed tomography angiography and magnetic resonance angiography on the diagnosis of musculoskeletal soft tissue tumors are described and analysed.

Objective:To investigate the relationship between meaning in life and procrastination of college students, and whether time value plays an mediating role between them.Methods:A total of 605 college students in Guizhou completed general procrastination scale, time value scale and life meaning scale.SPSS 22.0 software and PROCESS maro program were used for descriptive statistics, correlation analysis and mediating effect exploration.Results:(1) The procrastination score of college students was (34.40±7.74), the score of time value was (33.17±4.41), and the score of meaning in life was(46.03±8.81). (2) Procrastination was negatively correlated with meaning in life and time value ( r=-0.38, -0.16 respectively, P<0.01). While meaning in life was positively correlated with time value( r=0.31, P<0.01). (3) The mediating effect of time value perception between meaning seeking and procrastination was 22.6%.The direct effect of meaning in life on procrastination was 77.4%. Conclusion:College students with high meaning seeking is less procrastination, and time value mediates the effect between procrastination and meaning in life.Improving college students' meaning in life is conducive to indirectly reducing procrastination through time value.

Objective To evaluate arthroscopic reconstruction of a torn anterior cruciate ligament with either a central-third bone-patellar tendon-bone autograft or a two-strand semitendinosus-gracilis autograft and compare the results of clinical testing, satisfaction and functional status. Methods A retrospective study was done on 49 cases undergoing reconstruction with an ipsilateral central-third bone-patellar tendon-bone autograft and 54 treated with an ipsilateral two-strand semitendinosus-gracilis autograft. Patients were followed up for an average of 31.6 months (24-48 months). At the time of final follow-up, patients in each group were evaluated by Lysholm knee score, International Knee Documentation Committee (IKDC) rating scale and KT-1000 arthrometer for ACL ligament stability. Results No statistical difference was found between the groups in regard of the Lysholm knee score, overall IKDC score or KT-1000 arthrometrical measurements that stand for patient satisfaction, knee function and objective stability, respectively. The patellar tendon procedure group had a significantly higher knee pain rate than the hamstring group (37% versus 11%). Conclusions The bone-patellar tendon-bone autograft and the two-strand semitendinosus-gracilis autograft can attain comparable results for anterior cruciate ligament reconstruction in regard to patient satisfaction, knee stability and knee function in the medium-term follow-up. However, reconstruction of anatomic attachment sites, firm initial fixation and a structured postoperative rehabilitation program may have more influence on clinical outcomes and knee stability.

ObjectiveTo explore pathogenesis of headache after subarachnoid hemorrhage (SAH) whether related with immune inflammatory reaction in subarachnoid and observe the effect of immunosuppressive action of dexamethasone on headache.Methods80 patients who was consciousness and complained headache after SAH were randomly divided into four groups, treated only with mannitol, mannitol plus cerebrospinal fluid (CSF) replacement, intrathecal and vein injection with dexamethasone. Effects of four groups were observed.ResultsEfficiencies of four groups were respectively the mannitol group 27.27%, the permutation group 66.67%, the intrathecal group 92.36% and the vein group 30.00%. There was a significantly difference between the intrathecal group and other three groups, and the time of headache remission for intrathecal group was also longer than that of other three groups (P<0.01).ConclusionThe wide immune inflammatory responses in subarachnoid induced by degenerative and hemic CSF is likely main cause of headache after SAH and intrathecal injection with dexamethasone has an obviously effect.

Objective To study the clinical effect and complication of the combination treatment of lamivudine and adeforvir dipivoxil in decompeasated hepatitis B cirrhosis. Methods Eighty-six cases of decompensated hepatitis B cirrhosis were divided into the observation group and the control group with 43 eases each by random digits table. The control group was treated with routine treatment and lamivudine, and the observation group was added with adefovir dipivoxil on the base of the treatment in the control group. The clinical effect after 12 months' treatment was evaluated. Results After 12 months'treatment, the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), albumin ( ALB ) and Child-Pugh grade had significant improvement than that before the treatment in two groups(P < 0.05 ), and in the observation group they improved more obvious (P <0.05). The frequence of seroconversion of HBeAg/HBeAb and HBV DNA in the observation group was higher than that in the control group [86.05%(37/43) vs. 65.12%(28/43),79.07% (34/43) vs. 55.81%(24/43)], and the difference between the two groups was significant (P < 0.05 ). Seven cases of times complications happened in the control group and 8 cases of times complications happened in the observation group and the difference between the two groups was not significant (P > 0.05 ). Conclusion The effect of lamivudine and adefovir dipivoxil in the treatment of decompensated hepatitis B cirrhosis is superior to the only lamivudine.
