Background and purpose:Thermal ablation (radiofrequency ablation, RFA/microwave ablation, MWA) is the most commonly used minimally invasive technique for the treatment of liver cancer. Real-time shear wave elastography (SWE) is a new type of ultrasonic imaging technology, which was used in our study to monitor thermal ablation of liver cancer. This study aimed to investigate the stiffness change of liver cancer and that of surrounding liver parenchyma before and after thermal ablation, and to evaluate the application of SWE for monitoring thermal ablation for liver cancer.Methods:From Oct. 2014 to Apr. 2015, a total number of 36 patients, with 39 lesions, were treated with RFA or MWA and got complete response. SWE examination was performed before and after ablation. The SWE-mean, SWE-min, SWE-max, SWE-SD of lesions and the surrounding liver parenchyma were measured. Statistical analysis was made to compare the stiffness changes of liver cancer with those of the surrounding liver parenchyma before and after thermal ablation, and to determine whether there were differences between two different ablation modes.Results:Before and after ablation, the SWE-mean of lesions was (30.09±11.67) kPavs (52.11±17.56) kPa,SWE-min was (10.46±8.22) kPavs (20.57±11.42) kPa, SWE-max was (51.50±20.84) kPavs (88.54±27.75) kPa, SWE-SD was (10.63±4.30) kPavs (16.89±7.72) kPa; There were statistically signiifcant differences (P<0.05). Before and after ablation, the SWE-mean of surrounding liver parenchyma was (8.84±2.82) kPavs (8.91±2.78) kPa, SWE-min was (4.77±1.95) kPavs (4.69±1.90) kPa, SWE-max was (13.82±3.79) kPavs (14.34±3.97) kPa, SWE-SD was (3.24±1.32) kPavs (3.37±1.29) kPa; There were no statistically signiifcant differences (P>0.05). After ablation, the SWE-mean of RFA and MWA was (45.55±10.91) kPavs (60.59±20.99) kPa, SWE-min was (18.95±8.86) kPavs (25.93±10.93) kPa, SWE-max was (76.58±15.51) kPavs (104.01±32.59) kPa, SWE-SD was (13.82±3.52) kPavs (20.85±9.77) kPa; There were statistically signiifcant differences (P<0.05).Conclusion:SWE can quantitively analyze the stiffness of lesions. The ablation zone became stiffer after RFA or MWA, and the ablation zone of MWA was stiffer than that of RFA. Two kinds of ablation methods did not signiifcantly affect the stiffness of liver parenchyma around the lesion. SWE could potentially be used to monitor thermal ablation of liver cancer.

Objective To investigate the diagnostic value and the efficacy of magnetic resonance tomographic angiography(MRTA) in identifying the relationship between nerves and blood vessels of the patients with idiopathic trigeminal neuralgia.Methods Clinical and MR data of 280 ITN patients were analyzed retrospectively,and then were compared with operation results by using blind con-trol trials.Results Of the 280 ITN patients,there were a total of 267 patients with neurovascular contact,dubious contact or com-pression in affected sides (positive rate:95.3%),and 66 patients in normal sides (false positive rate:23.6%).And of 120 surgical patients,1 18 were found to have neurovascular contact or compression during the operation.There was significant statistical differ-ence between the neurovascular contact or compression in affected sides and that in normal sides (P <0.05).Using operation results as the gold standard,the specificity,sensitivity and the diagnostic accordance rate of MRTA in diagnosing neurovascular contact or compression were 100%,96.6% and 96.7% respectively.Conclusion MRTA can reliably display the relationship between nerves and blood vessels with higher diagnostic sensitivity and accuracy,thus providing the objective basis for the etiological diagnosis of and surgical treatment for ITN.

In this paper, the number of rhizosphere and non-rhizosphere microbial organisms of fusarium wilt resistant and susceptible watermelon under soil culture and soilless substrate culture was studied by traditional culture methods. The results showed that, the number of rhizoshpere microorganisms was significantly higher than non-rhizosphere, and the number was changed with the stage of watermelon grow, the number was the lowest in seedling stage and increased with the watermelon grow, and achieved highest at the flowering and fruiting stage, decreased with the watermelon ageing. The fusarium wilt resistant of watermelon was correspondence with number of rhizosphere bacteria; the number of rhizosphere bacteria of resistant watermelon was higher than that of susceptible watermelon in each stage under soil culture and soilless culture. The fusarium wilt resistant of watermelon is no correspondence with number of rhizosphere fungi and actinomycete. The number of non-rhizosphere microbial organisms was changed in a small range in the whole growing stage. The non-rhizosphere bacteria have no significant change in the whole stage under soil culture and increased quickly under soilless substrate culture and decreased at the later stage. The non-rhizosphere fungi and actinomycete reached highest at the later stage under soil culture or soilless sub-strate culture.

The traditional culture methods and the molecular biology methods were used to study the rhizosphere bacterial diversity between fusarium wilt resistant and susceptible watermelon. The results showed that the diversity and the equality of cultured rhizosphere bacteria of resistant watermelon were higher than those of the susceptible watermelon. The reason was that the cultured rhizosphere bacterial di- versity index H′ and 1/D of the resistant watermelon were higher than those of the susceptible watermelon and that the cultured rhizosphere bacterial equality index E of the resistant watermelon were higher than those of the susceptible watermelon. The dominant cultured bacterial genotypes were different between re- sistant and susceptible watermelon. The genotype 1 is the dominant genotype of resistant watermelon, con- sists 51.1%. The genotype 7 is the dominant genotype of susceptible watermelon, consists 58.7%.

Objective To study the clinical and radiographic characteristics of complicated axis fractures combined with adjacent segment instability and explore reasonable surgical treatment strategy. Methods A retrospective study was performed on 21 patients with axis fractures treated from August 2003 to June 2009. There were 14 males and 7 females at mean age of 34 years. The treatment strategy was based on the fracture type and the stabilities of adjacent atlantoaxial joint and intervertebral C2/3.Treatment strategies included anterior C2/3 interbody discectomy and fusion, anterior cervical plate internal fixation, odontoid screw fixation, posterior C1-2 pedicle screw fixation, cervical lateral mass screw fixation or combined anteroposterior approach. Results All patients were immobilized in a hard collar for thee months and followed up for 6-36 months (average 12 months), which showed bony fusion and cervical stability, with no intraoperative surgery-related complications such as loosening, extrusion or breakage of fixation, vertebral artery injury, nerve damage, cerebrospinal fluid leakage or wound infection. Neurological recovery was observed in five patients. Conclusions For complicated atlas fractures, correct identification of fracture type and instability disturbance of adjacent atlantoaxial joint and C2/3 as well as active treatment can conduce to better effect.
