2.Diagnosis and treatment of primary intraocular lymphoma
Recent Advances in Ophthalmology 2017;37(6):597-600
Primary intraocular lymphoma (PIOL) is mostly composed by diffuse large B-cell lymphoma with a high degree of malignancy and often masquerades as uveitis.Moreover,it has a poor prognosis,therefore the early diagnosis and treatment are very important.Cytology,cytokine analysis,immunohistochemistry and genetic testing are often used in combination to improve the diagnosis rate of PIOL,however,eye tissue biopsy is the gold standard for diagnosis of PIOL.Currently,since there is no unified treatment program,the main treatment is given priority to local chemotherapy and orbital radiotherapy,and the use of multiple therapies can improve the efficacy of refractory PIOL.Base on these,this article reviews the current diagnosis and treatment for providing certain reference.
3.TACE combined with CT-guided ~(125)I radioactive particle implantation for the treatment of hepatic cancer
Journal of Interventional Radiology 2009;18(9):702-704
Objective To investigate the technical points and the clinical effectiveness of transcatheter arterial chemoembolization (TACE) combined with CT-guided ~(125)I radioactive particle implantation for the treatment of liver cancer. Methods Twenty-seven patients with hepatic cancer, proved by color Doppler ultrasonography, CT and AFP, were enrolled in this study. All the patients received embolization therapy with lipiodol not long before. Of the 27 patients, preoperative CT scanning was performed in 16. Based on the CT findings, the therapeutic protocol was formulated to determine the amount and site of ~(125)I radioactive particle to be implanted. When drawing the outline of target area, the targeted sedimentation extent which was delineated on CT scan should be exceeded the area with deposits of lipiodol by 0.5-1.0 cm. The average energy of ~(125)I radioactive particle was 27-35 keV. Results Of 27 patients, complete remission was seen in 2, partial remission in 16, unchanged condition in 6 and exacerbation of the condition in 3, with a total efficiency of 66.7%. The patients were followed up for 6 months. One patient died of distant metastasis and the remaining ones survived so far. Conclusion Transcatheter arterial chemoembolization combined with CT-guided ~(125)I radioactive particle implantation is a safe and effective treatment for liver cancer.

Journal of Audiology and Speech Pathology 2009;17(3):215-219
Objective This paper is to explore the relationship between the placement of the bone oscillator and bone-conducted thresholds to ASSR stimuli in adults with normal hearing and to investigate the amplitude and the threshold differences to bone-conducted auditory steady-state responses (BC-ASSR) stimuli between single - and multiple-stimulus conditions. Methods Two groups of subjects were selected with 0. 5, 1, 2 and 4 kHz brief tones repeated at the rate of 77, 87, 93 and 101 Hz using a B-71 bone oscillator either in single- or multiple ted no significant differences between mastoid and behind-the-ear placements. The mean and standard deviations of bone-conducted behavioral thresholds to ASSR stimuli at 0.5, 1, 2 and 4 kHz were 62.6±4.8,47.1±4.8,46.8cant difference between the two conditions while the mean and standard deviations of BC-ASSR thresholds at 0.5, 1, 2 and 4 kHz were 96.7±9.7,70.3±11.6,60.6±7.4,52.8±7.2 dB re: 1μN (ppe), respectively. Conclusion The behavioral bone-conducted thresholds to ASSR stimuli with mastoid and behind-the-ear placemen yielded no significant differences. When the stimuli intensity was 50 dB nHL, the amplitudes in single-stimulus condition were significantly higher than those to multiple-stimulus condition. There were no significant differences for BC-ASSR thresholds between single- and multiple-stimulus condition.

Chinese Journal of Practical Nursing 2008;24(31):76-78
ObjectiveTo explore the effect of cognitive therapy and progressive relaxation training (CTPRT) on the operation anxiety of patients undergoing chemonucleolysis with collagenase.Methods120 patients undergoing chemonucleolysis with collagenase were randomly assigned to the experimental group and the control group.The experimental group received routine care and CTPRT,while the control group only received routine care.The perioperative anxiety status,back and leg pain,heart rate,blood pressure,status of sleeping and urination of the two groups were evaluated respectively.ResultsAnxiety and pain degree in the experimental group was significantly lower than that of the control group (P<0.01).About 30 min pre operation and postoperation,the heart rate and blood pressure of the experimental group were much lower than that of the control group (P<0.01).The experimental group also showed better sleep and urination status.ConclusionsThe cognitive therapy and progressive relaxation training can reduce degree of operation anxiety,release the pain and help promote sleep for patients undergoing chemonucleolysis with collagenase.
6.Role and action mechanisms of FZD5 in prostate cancer bone metastasis in mice.
National Journal of Andrology 2016;22(2):128-132
OBJECTIVETo investigate the action mechanisms of the FZD5 gene in prostate cancer bone metastasis and search for some new treatments for this disease.
METHODSWe determined the expression level of the FZD5 gene in prostate cancer PC3 cells and, after transfection of siRNA into the PC3 cells and silence of the FZD5 gene, observed the changes in the migration and proliferation of the cells. We established the model of prostate cancer bone metastasis by tibial injection of prostate cancer cells in the nude mice. Then we injected control siRNA and FZD5-silenced siRNA into the tibia of the mice followed by evaluation of tumor-induced bone destruction by X-ray imaging at 0, 1, and 3 weeks and by HE staining at 3 weeks after injection.
RESULTSAfter transfection of FZD5-silenced siRNA into the prostate cancer PC3 cells, the expression of the FZD5 gene was decreased about 70%. The rate of cell proliferation was significantly lower in the gene silencing group than in the control (P < 0.05), and that of cell migration dropped by 30% in the former as compared with the latter group at 48 hours after FZD5 silencing (P < 0.05). At 3 weeks after injection of control siRNA or FZD5-silenced siRNA into the tibia of the mice, osteolytic damage was observed in both groups, though less in the FZD5 silencing group, with only a few remaining bone trabeculae visible.
CONCLUSIONSilencing the FZD5 gene can reduce the migration and proliferation of prostate cancer cells, help to suppress bone metastasis and destruction, and thereby improve the survival rate and quality of life of the patients.

By using undecalcified bone sections, accompanied by tetracycline double labeling and analysis of infrared spectrogram, the bone formation, mineralization and crystal feature of induced ectopic bone and self femora in rats were compared. The results showed that from the 21th day to the 26th day as well as from the 26th day to the 30th day of the experiment, the rate of induced bone formation, mineralization was more active than that of the self femora: on the 30th day, in the induced bone, the count of bone cell was much more, the volume of bone cell was much larger too; but the crystal structure of induced bone was indentical with that of self femora. The molecular formula was Ca_5[(OH)/(PO_4CO_3OH)_3].
