Trans-cinnamaldehyde, the main component of volatile oil from cassia twig or Cinnamomum cassia, which is a traditional Chinese herbal medicine. Trans-cinnamaldehyde is a kind olefine aldehyde of organic compounds and has many pharmacological properties, such as anti-inflammatory, anti-tumor, anti-bacterial, antidiabetic, anti-obesity, and neuroprotection etc. The compound has preventive and therapeutic effects on the nervous system, cardiovascular, cancer, diabetes and other diseases. Trans-cinnamaldehyde, as a preventive care of nature medicine, has great clinical and market potential. This paper gives a review about the pharmacological effects and mechanism of trans-cinnamaldehyde researched in the latest five years. We hope to provide some basic information for further research on trans-cinnamaldehyde.

Objective To assess feasibility of three-dimensional(3D) reconstruction techniques and virtual gastroscopy of CT(CTVG)in diagnosing gastric tumors.Methods 22 cases doubted with gastric lesions were scaned by mutislice helic CT and reconstructed into CTVG and 3D images.The results were compared with fiberoptic gastroscopy(FG) and all of the cases were sure with gastric lesions and biopsied by gastroscopy or surgery operation.Results 22 patients was examinated successfully,and the lesions was proved by pathology of FG or operation.According to location and shape of lesions,there were more ulcer type(16) and more located at gastric antrum(14) in this specimen.Both CTVG and FG had one misdiagnosis respectively.Conclusion CTVG combined with 3D of MSCT is same sensitivity and specificity as FG.

Background and purpose:Correct target positioning is an important factor affecting the precision of stereotactic body radiotherapy (SBRT) in patients with lung tumors. This study investigated the setup errors in patients with malignant lung tumors receiving SBRT with cone-beam CT (CBCT) and analyzed the factors influencing setup errors.Methods:Twenty-nine patients with solitary malignant lung tumors were enrolled in the study. Each patient underwent SBRT with CBCT before each treatment. Setup errors in CBCT were obtained according to the matched and planned CT images in anterior-posterior (AP), superior-inferior (SI) and left-right (LR) directions. The expanding margins of clinical target volume (CTV) to planning target volume (PTV) according to the analyzed setup errors were then calculated. And the influencing factors of setup errors were analyzed.Results:A total of 155 CBCT images from 29 patients were obtained during the treatment. The setup errors were (-1.68±3.62), (-1.34±3.90) and (0.36±2.15) mm in the AP, SI and LR directions, respectively. The absolute setup errors were (3.16±2.42), (3.29±2.48) and (1.74±1.30) mm in the AP, SI and LR directions, respectively. The suggested expanding margins of CTV to PTV were 9.6, 10.0 and 5.3 mm in the AP, SI and LR directions according to the setup errors. The setup errors in the AP direction of peripheral lesions and in the SI direction of inferior, right and metastatic lesions were relatively larger(P=0.007, 0.008, 0.000 and 0.000)..Conclusion:In patients with malignant lung tumors receiving SBRT, the setup errors were more obvious in the SI and AP directions. Tumor motion management techniques including CBCT, breath-holding technique are required to reduce the setup error in patients with lung tumors receiving SBRT.

Identification and functional analyses of antiviral restriction factors in hosts have become hot research topics. Four HIV restriction factors, APOBEC3G, Trim5alpha, Tetherin, and SAMHD1, have been identified in recent years. By encoding auxiliary proteins, lentiviruses can counteract host restriction factors. For example, the auxiliary proteins Vif, Vpu, and Vpx of HIV antagonize APOBEC3G, Tetherin, and SAMHD1, respectively. Furthermore, these auxiliary proteins enable the entry of HIV into host cells and influence the replication and pathogenicity of HIV. In this paper, we review the research progress in the functions of the three HIV auxiliary proteins that can antagonize the host restriction factors.

Objective To study the value of clinical applications of multi-slice spiral CT(MSCT)3D reconstruction and MPR in knee joint traumatic fracture and the imaging technique of multi-slice spiral CT 3D.Methods 24 cases underwent MSCT and all data sets were done 3D and MPR in ADW 3.1 workstation.Results 3D reconstruction can indicated the site,direction of alignment,fracture degree,colapse,displacement length of trauma knee joint,MPR can viewed damage inside the bone.Conclusion 3D reconstruction and MPR has high application value in clinical diagnosis and choosing therapy methods.

Objective To study the correlation of measuring bone density for diagnosing osteoporosis between VQCT and DXA. Methods 50 patients were measured bone density coinstantaneous by DXA and VQCT. All of the data was saved in computer and analyzed by SPSS soft.Results According to WHO criterion 14 patients were osteoporosis by F-DXA and 9 by S-DXA,and 23 by VQCT.The percent was respective 28%,18% and 46%. The results of VQCT were significantly different from the results of F-DXA and S-DXA (?

OBJECTIVETo explore the clinical effects of PLIF surgery for elderly patients with lumbar degenerative disease.

METHODSFrom March 2010 to May 2013, 28 patients with lumbar degenerative disease, aged more than 80 years were treated with PLIF surgery. There were 10 males and 18 females, aged from 80 to 93 years old with an average of (85.44±3.66) years. Course of disease was from 3 to 20 years. The operation time, intra-operative blood loss, operation complications were recorded and JOA scores and Macnab criteria were used to evaluate the clinical outcomes.

RESULTSAll patients were followed up from 12 to 40 months with an average of 26.5 months. The average operation time was (150.00±26.42) min and the average intra-operative blood loss was (373.33±99.88) ml. The pre-operative JOA score was 12.30±2.43, and the corresponding postoperative JOA score at the final follow-up was 24.81±2.09 which was much higher than the preoperative one (P<0.01). According to the modified Macnab criteria to evaluate at the final follow-up, 16 patients got an excellent result, 10 good, 2 fair. In the weeks postoperatively, injuries of nerve root happened in 3 cases, superficial wound infection with delayed healing in 3 cases, and tear of the dural sac accompanied with cerebrospinal fluid leakage in 1 case. After long term follow-up, adjacent segment degeneration and the corresponding spinal canal stenosis occurred in 1 case at 34 months after operation. All cases got successful fusion without any displacement of internal fixation and pseudoarthrosis formation.

CONCLUSIONWith proper cases, fully preoperative preparation, perfect intra-operative manipulation and active treatment after operation, even advanced ages older than 80 years with lumbar degenerative disease could get satisfactory outcomes after PLIF surgery.
