The Baculoviridae are a large family of enveloped DNA viruses exclusively pathogenic to arthropods. Baculoviruses have been extensively used in insect cell-based recombinant protein expression system and as biological pesticides. They have been deomostrated to be safe to mammals, birds and fish. Recently, baculoviruses has been shown to transduce different mammalian cells in spite of the fact that they cannot replicate in mammalian cells (11, 73, 76). This has resulted in the development of baculoviruses as mammalian expression systems and even as vestors for gene therapy.

Purpose To investigate the effect of two different 1.5T MRI scanners on the apparent diffusion coefficient (ADC) measurement and its reproducibility in diffusion weighted imaging (DWI) of the liver. Materials and Methods Two groups of volunteers (33 people in each group) underwent liver DWI examination twice by using the same DWI sequence with b value of 0 and 800 s/mm2 on different MRI scanners (1.5T Siemens Espree and 1.5T Philips Achieva). On ADC maps, two region of interests were placed on three central slices of the left and right liver lobes, respectively. The ADC measurements of six region of interests on left and right liver lobes were averaged to represent the mean ADC values of the left and right liver lobe, respectively. The reproducibility of the ADC measurements was assessed by Bland-Altman method. Results The ADC values of the left and right liver lobes measured on Siemens MRI scanner were significantly higher than those on Philips MRI scanner (t=2.045-2.713, P<0.05); on both scanners, the ADC values of the left liver lobe were significantly higher than those of the right liver lobe (t=-10.561--7.263, P<0.001). The Bland-Altman results showed that the reproducibility of ADC measurement was similar on both MRI scanners, and both displayed higher reproducibility of right liver lobe than that of left liver lobe (on Siemens MRI scanner: the agreement were 16.65% and 7.55% for the left and right liver lobe, respectively;and on Philips MRI scanner:16.30%and 7.85%, respectively. Conclusion Different MRI scanners may have influence on ADC values, but does not affect its reproducibility. Therefore, when ADC values obtained on different MR scanners are compared in clinical analysis, this influence should be considered.

Objective:To evaluate the biochemical and structural changes of apatinib in patients with progressive radioactive iodine-re-fractory differentiated thyroid cancer (RAIR-DTC). Methods:The participants (n=10) were followed up since March 2016. Treatment ef-fect was evaluated in using both biochemical [thyroglobulin (Tg) and thyroglobulin antibody (Tg-Ab)] and structural responses (target lesions, TL). Adverse events were also recorded over time. Results:The median follow-up was 7.9 months. The Tg level declined rapid-ly within 6 weeks after apatinib treatment, and the average decline ranged from 60%to 90%, indicating the immediate biochemical re-sponse of apatinib in progressive RAIR-DTC. The Tg level tended to stabilize thereafter. However, the Tg level rebounded by 4%–135%when withdrawal was performed for 3–14 days. The number of TLs decreased rapidly within 8 weeks, and the average decreased ranged from 40%to 60%, indicating the presence of rapid structural responses. Thereafter, the number of TLs continued to stabilize. TLs, in contrast to Tg, were not significantly affected by drug withdrawal. The rate of change in Tg (Tgvn) was positively correlated with the rate of change in TL (TLvn) [TLvn=0.17×Tgvn+0.50 (r=0.56, P<0.05)]. The apatinib dose was adjusted due to adverse events, which could be relieved after 3 to 14 days of withdrawal. Apatinib can effectively control the disease even at a reduced dose of 250 mg/d. Conclusion:Apatinib treatment showed a fast and sustainable biochemical and structural responses. Tg could be regarded as an objec-tive indicator. Tgvn is positively correlated with TLvn, and the response of Tg is more sensitive than that of TLs.
