Chinese Journal of Radiology 2001;0(03):-
Objective To determine the effect of reducing mA on the diagnostic quality of images and the radiation dose to the lens in patients undergoing paranasal sinus CT. Methods Fifty patients undergoing paranasal sinus CT at 200 mA or 50 mA. The lens dose was measured using thermoluminescent dosemeters [LiF(Mg?Cu?P)]. Image quality was evaluated for six anatomical structures, including middle turbinate, uncinate process, maxillary ostium, ethmoid infundibulum, frontal recess, and cribriform plate. These anatomical structures were assessed as: not seen (0 points), demonstrated but not clearly visualized (1 points), or clearly demonstrated (2 points). Results Mean radiation dose to the lens was significantly reduced from 7.339 mGy (200 mA) to 1.108 mGy (50 mA). No significant difference of image quality between the two mA protocols was found in either rhinosinusitis group or non-rhinosinusitis group. And for rhinosinusitis the image quality showed no significant difference between high-resolution arithmetic and soft arithmetic. Conclusion CT scanning of the sinuses can be performed at greatly reduced mA without loss of diagnostic quality of the images. As far as the rhinosinusitis is concerned, high-resolution arithmetic can not improve the image quality and soft arithmetic is enough.

Chinese Journal of Experimental Ophthalmology 2013;(4):339-346
Background C57BL/6.NOD-Aec1Aec2 mouse is considered to be an idea model for the study of the pathogenesis of Sj(o)gren syndrome,but the cause of dry eye in these mice is unclear.Objective This study was to investigate the histopathological change of the ocular surfaces of C57BL/6.NOD-Aec1Aec2 mice,and to determine whether dry eye is developed spontaneously in these mice.Methods Forty-five clean C57BL/6.NOD-Aec1 Aec2 mice were used as the experiment group and forty-five C57BL/6J mice(both male and female)were used as the control group in this study.Detection of fasting blood-glucose,Schirmer' s test Ⅰ (S Ⅰ t),lissamine green staining and scoring of the corneal and conjunctival epithelium in the mice were performed at the age of 4,8,12,16 and 20weeks.Five mice from each group were sacrificed and their corneas were obtained to measure the central corneal epithelium thickness and to count the number of conjunctival goblet cells.In addition,lymphocyte infiltration in the lacrimal gland of the mice was examined with hematoxylin-eosin staining.The uhrastructure of the corneal epithelial cells and microvilli were assessed by scanning electron microscopy.The use and care of the mice were approved by the Experimental Animal Care Committee of the Third Military Medical University.Results No sign of dry eye was seen in both the 4-week-old C57BL/6.NOD-Aec1Aec2 mice and 4-week-old C57BL/6J mice.The S Ⅰ t values in 8-week-old,12-week-old,16-week-old and 20 week-old mice from the experiment group were (2.7 ±0.9) mm,(2.5 ±0.8) mm,(1.8±0.6) mm and (1.9± 0.1) mm,respectively,showing a significant reduction in comparison with those of the control mice of the same age(all P<0.01).The amount of lissamine green staining in the C57BL/6.NOD-Aec1Aec2 mice gradually increased with age,showing elevated scores in 12-week-old,16-week-old and 20-week-old mice in the experiment group(all P<0.01).The central corneal epithelium thicknesses were(20.18±3.75)μm,(17.01 ±5.25) μm,(14.19±5.72) μm and(12.00±3.25) μm in the 8-week-old,12-week-old,16-week-old and 20-week-old C57BL/6.NOD-Aec1Aec2 mice,respectively,which were significantly lower than those of the C57BL/6Jmice of the same age (all P<0.01).The numbers of conjunctival goblet cells were (8.2±2.4),(6.2±2.1),(6.1 ±2.2) and (4.1 ± 2.0) in the 8-week-old,12-week-old,16-week-old and 20-week-old C57 BL/6.NOD-Aec 1Aec2 mice,respectively,showing a gradual decrease with age and a significant decline in comparison with those of the C57BL/6Jmice of the same age(all P<0.01).Lymphocyte infiltration in the lacrimal gland and destruction of gland ducts were seen by hematoxylin-eosin staining,and acinar abnormality aggravated with aging.Reduction of corneal epithelial cells and the number of microvilli were distinguished with aging under the scanning electron microscope.The fasting bloodglucose levels of the two groups were both less than 6.0 mmol/L,and no significant difference was found between them at any age(P=0.637,0.610,0.163,0.086,0.938).Conclusions C57BL/6.NOD-Aec1Aec2 mice develop dry eye spontaneously with aging.The course of disease and characteristics of dry eye in C57BL/6.NOD-Aec1Aec2mice is similar to human dry eye.The C57BL/6NOD-Aec1 Aec2 mouse is the perfect model to study the pathogenesis of dry eye.
4. Effects of recombinant human insulin-like growth factor-1 on the phosphorylated serine-threonine protein kinase and apoptotic cells in edematous perihematomal brain regions following experimental intracerebral hemorrhage in rats
Chinese Journal of Cerebrovascular Diseases 2012;9(2):82-86
Objective: To investigate recombinant human insulin-like growth factor-1 (rhIGF-1) on the phosphorylated serine-threonine protein kinase (pAkt) and apoptotic cells in edematous perihematomal brain regions following experimental intracerebral hemorrhage in rats. Methods: A total of 78 healthy male rats were randomly assigned to a false operation group (n =6), a cerebral hemorrhage control group (control group for short, n=36) and a rhIGF-1 intervention group (intervention group for short, n=36). According to 6 time points after giving intervention measures, the rats of the control and intervention groups were randomly redivided into 6 subgroups: 6 h, 12 h, 1 d, 2 d, 4 d, and 7 d subgroups (n =6 in each subgroup). A rat model of acute cerebral hemorrhage was induced by stereotaxic injection of collagenase type IV. RhIGF-1 (50 μg/kg) was injected via tail veins in the intervention group, once a day, until the end of the experiment. An equivalent isotonic saline was injected via tail veins each day in the sham operation and control groups. Samples were taken from each group at a specified time. An immunohistochemical method was used to observe the expression of pAkt around hematomas ; deoxynucleotidyl transferase-mediated terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) technique was used to observe apoptotic cells. Results: Circled digit oneThe neurological deficit score of the rats in the control group and intervention group reached the highest at day 1 or day 2 after procedure, then decreased gradually. The only score in the intervention group at day 7 after procedure was lower than that in the control group. The difference was statistically significant (P <0. 05). Circled digit twoThere were only a few expressions of pAkt positive cells in rats of the false operation group. Except the 6-hour time point, the numbers of pAkt positive cells at the remaining time points in the intervention group were higher than those in the control group. The difference was statistically significant (P < 0. 05). Circled digit threeOnly a few TUNEL positive cells were observed in the false operation group. Except the 6-hour time point, the numbers of TUNEL positive cells at the remaining time points in the intervention group were significantly lower than those in the control group. The difference was statistically significant (P < 0. 05). Conclusion: RhIGF-1 may reduce apoptosis after cerebral hemorrhage and improve the neurological function. Its role may be associated with the activation of pAkt.

Objective To analyze the indications of clip deployment and influencing factors for clip dislocation immediately after stereotactic vacuum-assisted breast biopsy. Methods One hundred and fourteen microcalcifications in 108 women aged 35 to 85 years old (median 63 years) underwent 11-gauge stereotactic vacuum-assisted breast biopsy. Every lesion was marked on biopsy site with Gel Mark Ultra clips (n = 82) or MicroMark Ⅱ clips ( n = 32) after biopsy. All microcalcifications were classified 3 mono-focal groups: < 10 mm, 10--20 mm, > 20 mm and one muhi-focal group according to its diameter and distribution. The distances between clips and biopsy sites were directly measured on post-biopsy craniocaudal and mediolateral mammograms. The distance was recorded as < 10 mm, 10--20 mm and >20 mm. Results 88% (22/25) of mono-focal microcalcifications smaller than 10 mm and 70% (14/20) of mono-focal microcalcifications measured 10--20 mm were completely removed on mammograms, whereas none of mono-focal microcalcifications larger than 20 mm (n = 17) was completely removed. 65.8% (75/114) of the clips were accurately located. Thirty-nine clips were dislocated on at least one projection with 87.2% (34/39) of the clips dislocated only along the needle track, which is called "accordion effect". Hematoma was found in 4 patients, and the clip was accurately localized only in one case with hematoma, Conclusions Clips should be deployed as a standard procedure for mono-focal microcalcifications smaller than 20 mm and all multi-focal mierocalcifications. The major reasons for clip dislocation immediately after biopsy are the accordion effect and hematoma.

Journal of China Medical University 2016;45(4):349-351
Objective To investigate whether hyperbaric oxygen(HBO)affected neuropathic pain through autophagy and verify the HBO effect. Methods A total of 60 male SD rats were selected for the study and randomly divided into 4 groups:control group(C group),sham operation group (S group),chronic constriction group(CCI group)and hyperbaric oxygen group(HBO group). LC3Ⅱand P62 were determined by Western blot method and the autophagy was detected by electron microscopy on the 7th day. Results CCI and HBO groups were significantly higher than C and S group in Western blot(P<0.05). There was no difference between group C and group S(P>0.05). The expression of LC3Ⅱin HBO group was significantly higher than that in CCI group(P<0.05). And the expression of P62 in CCI group was significantly higher than that in HBO group(P<0.05). The autophagy in CCI and HBO group were significantly increased comparing to the C and S groups(P<0.05). However,the difference be?tween group C and S was not significant(P>0.05). Conclusion Hyperbaric oxygen therapy can induce autophagy for anti?neuropathic pain.
