Objective:To give the test in cases of changing the conditions of measurement and reference value, compare the test results, and detect the capacity of QuickCheck, so as to offer reference for the daily morning check of accelerator and the evaluation of test results. Methods:Change the output dose, field size, SSD, angle of collimator and gantry angle of the accelerator, and then evaluate QuickCheck’s capacity of monitoring accelerator accordingly. Compare the field parameters measured by QuickCheck with the data from the 3D water tank. Results:When the output dose was 1 cGy higher than the reference value or 6 cGy lower than it, the field size expanded or contracted more than 2 cm simutaneouly, SSD was 2 cm higher or 1 cm lower than reference value, the collimator rotated more than 2 °, the gantry angle rotated more than 6 °, and then the test results of QuickCheck surpassed threshold. Comparing the measuring results of QuickCheck with 3D water tank, the difference between the flatness of the two was 3.84%, symmetry (G/T) 0.67%, symmetry (L/R) 0.47%and dose rate 1.2 MU/min. Conclusion:QuickCheck is rather accurate in testing the output dose, field size, angle of collimator, flatness, symmetry and dose rate, so it could meet the requirement of accelerator’s daily QA. However, its capability is relatively poor on examining SSD and the deviation of gantry angle.

1. Microsurgical relationships of the arteries at the base of the brain and the trigeminal nerve were studied bilaterally on 30 brains. Twenty seven trigeminal nerves made contact with the arteries 33 times which represents 55 percent of the cases. Six of 27 trigeminal nerves had double contact.2. Of 33 arteries in contact with 27 nerves, seventeen involved the superior cerebellar arteries (SCA) (28.33?5.82%), seven the anterior inferior cerebellar arteries (AICA) (11.67?4.15%) and nine the middle inferior cerebellar arteries (MICA) (15.0?4.61%).3. The outer diameter of the superior cerebellar artery is the largest averaging 1.41?0.20 mm; the anterior inferior cerebellar artery comes next averaging 1.06?0.36 mm and the middle inferior cerebellar artery the smallest, averaging 0.62?0.14 mm.4. 27 trigeminal arteries arising from the upper or middle segement of the basal artery were found on the ventral surface of the trigeminal nerves in 17 brains, and 16 trigeminal branches arising from the AICA. MICA. and PICA were also found at the roots of 16 trigeminal nerves. Anastomoses were noted between the trigeminal arteries and the trigeminal branches in four cases of 16 trigeminal nerves.5. The association between the neurovascular contact and the trigeminal neuralgia are discussed. It is suggested that the neurovascular contact either from dorsal or ventral aspects may be the anatomical cause of the trigeminal neuralgia.6. The neurovascular contact of the trigeminal nerve with the SCA was usually on the dorsal or dorsalmedial aspect of the nerve, but the point of contact with AICA or MICA was mainly on the ventral aspect of the nerve. Besides, there are trigeminal arteries and trigeminal branches at the ventral surface of the nerve. All these topographic observations provide microsurgical information for neurosugeons.

Aiming at the problem of high-quality image reconstruction from projection data at sparse angular views, we proposed an improved fast iterative reconstruction algorithm based on the minimization of selective image total variation (TV). The new reconstruction scheme consists of two components. Firstly, the algebraic reconstruction technique (ART) algorithm was adopted to reconstruct image that met the identity and non-negativity of projection data, and then, secondly, the selective TV minimization was used to modify the above image. Two phases were alternated until it met the convergence criteria. In order to further speed up the convergence of the algorithm, we applied a fast convergence technology in the iterative process. Experiments on simulated Shepp-Logan phantom were carried out. The results demonstrated that the new method not only improved image reconstruction quality and protected the edge of the image characteristics, but also improved the convergence speed of the iterative reconstruction significantly.

In order to guarantee the safety and accuracy of the whole treating process as well as better link up of each section during the treatment, we did research in order to establish a project concerning the process quality control (PQC) of treating liver cancer with CyberKnife. From the safety and accuracy point of view, we divided the whole process of treating liver cancer with CyberKnife into ten links, i.e. the registration of patients' information, the im plantation of fiducial markers, fixation of body posture, CT localization, target delineation, design of the treatment plan, quality assurance in physics, implementation of the treatment plan, inspection on the correctness and data archiving. We analyzed the possible mistakes in each link and the consequences brought by them. To smoothly connect all the links, a special part "Attention" was added between every two links. Various wrong operations which may influence the safety and accuracy of treatment were illustrated, and the consequences brought by them were also ex plained. The "Attention" part among links offers important information for the next step, and gives us reminding and warnings. The project of quality control covers all the important links when treating liver cancer with Cy berKnife. It offers regulations, reminding and warning for us so that the safety and accuracy of treatment can be guaranteed, and the work of all staff could be closely connected.

9. Effect of sex combing protein 1 on proliferation and differentiation of osteoblasts in inflammatory microenvironment
Chinese Journal of Tissue Engineering Research 2020;24(1):130-135
BACKGROUND: Studies have shown that the loss of sex combing protein 1 (Asxl1) can lead to the occurrence of bone dysplasia and bone defects, but the relationship between this factor and bone destruction in the microenvironment of apical periodontitis has not been reported. OBJECTIVE: To study the effect of Asxl1 on proliferation and differentiation of osteoblasts in an inflammatory microenvironment. METHODS: MC3T3-E1 cells were excited by lipopolysaccharide to establish an in vitro inflammatory microenvironment. The best concentration and optimal action time of lipopolysaccharide were screened by cell counting kit-8 test. MC3T3-E1 cells were then stimulated with 20 mg/L lipopolysaccharide for 24 hours. The expression levels of Asxl1 protein and mRNA were detected by immunofluorescence and real-time PCR, respectively. After lipopolysaccharide stimulated the formation of inflammatory microenvironment, Asxl1-Si RNA was transfected for 24 hours, cell counting kit-8 was applied to detect the activity of cell proliferation, and real-time PCR was used to detect the expression levels of Asxl1 and osteogenic related genes ALP and RUNX2 mRNA. RESULTS AND CONCLUSION: After lipopolysaccharides stimulation of MC3T3-E1 cells, the expression levels of Asxl1 protein and mRNA were decreased. Under the inflammatory microenvironment, the proliferation activity of MC3T3-E1 cells transfected with Asxl1-Si RNA for 24 hours was significantly decreased, and the expression levels of Asxl1, ALP and RUNX2 mRNA were markedly decreased. These findings indicate that Asxl1 may influence the proliferation and differentiation of osteoblasts by involvement in the process of inflammatory reaction, thereby participating in bone destruction.

Objective To construct the recombinant RIP3 over-expressed plasmids and transfect them in breast cancer MCF7 cells, and identify the expression and localization of fusion protein, as well as its effect on the death way of MCF7 cells. Methods The expression levels of RIP3 mRNA in four breast cancer cell lines and normal mammary epithelial cells were detected by reverse transcription polymerase chain reaction (RT-PCR). The RIP 3 coding sequence was amplified by polymerase chain reaction and subcloned into mCherry vector to construct recombinant plasmids. The plasmids were transfected into MCF7 cells by lentivirus after DNA sequencing, then screened by basticidin (4 mg/L) for 1 week. The efficiencies of RIP3 expression were validated by Western blotting assay. The death way of mCherry-RIP3-MCF7 cells was observed under the treatment of TNF-αand Z-VAD-FMK. Results The lowest expression of RIP3 mRNA was found in MCF7 cells. The sequencing results validated the well recombinant plasmids. The expression of mCherry-RIP3 fusion pro-tein with a molecular weight of 85 ku was detected by Western blot assay. The mCherry-RIP3 expression enhanced the sensi-tivity of MCF7 cells to TNF-αand Z-VAD-FMK induced cell death. Conclusion The recombinant RIP3 over-expressed plasmids were successfully constructed, and the stable MCF7 cells with ectopic RIP3 transfection were obtained. The mCher-ry-RIP3 fusion protein was expressed in the cytoplasm and was conformed to mediate TNF-αinduced necroptosis.
