Background Conventional chemical method to fix the entire eyeball results in the edema of retinal nerve fiber layer and therefore influent the evaluation of tissue structure.Research showed that microwave irradiation can avoid this phenomenon. Objective This study was to investigate the appropriate energy and time duration of microwave irradiation for fixation of rabbit eyes specimen and compare the influence of different fixation methods on retinal structure. Methods Twenty-two New Zealand white rabbits were sacrificed by using venous air embolism.The eyeballs were enucleated from the rabbits and immersed in chemical reagents with glacial acetic acid,methyl aldehyde and chloroform for 2 days as the control group.The eyeballs were immersed in 400 ml physiological balance solution immediately,and then were fixed by microwave irradiation for 80,160,240 and 320 seconds under the lower power as the microwave irradiation groups.In the microwave irradiation+chemical fixation group,the specimens were immersed in chemical reagents for 1-2 hours after the microwave radiation.The morphology of retinal structure was examined and area of retinal detachment was calculated by hemotoxylin and eosin staining under the light microscope. Results A better fixation effect was obtained in the retinal section of microwave radiation for 240 seconds in comparison with that of the traditional chemical reagent fixation method for 2 days.The retina detachment ratio was 16.3%±11.5% for simple microwave method,50.0%±24.5% for chemical method,and 6.7%±7.8% for microwave+chemical method.showing a significant difference among 3 groups(F=32.43,P=0.000).Retinal staining was clear and retinal structure was almost normal in the specimens of microwave+chemical fixation group with 200-240 seeonds microwave irradiation and 1-2 hours chemical fixation. Conclusion Microwave irradiation method is a more ideal way for the fixation of retina because of taking short duration,lower toxicity and better staining.The combination of microwave radiation and chemical reagents can acquire an excellent quality of retinal section.

Chronic myeloid leukemia (CML) is characterized by the accumulation of active BCR-ABL protein.Imatinib is the first-line treatment of CML;however,many patients are resistant to this drug.In this study,we aimed to compare the differences in expression patterns and functions of time-series genes in imatinib-resistant CML cells under different drug treatments.GSE24946 was downloaded from the GEO database,which included 17 samples of K562-r cells with (n=12) or without drug administration (n=5).Three drug treatment groups were considered for this study:arsenic trioxide (ATO),AMN107,and ATO+AMN107.Each group had one sample at each time point (3,12,24,and 48 h).Time-series genes with a ratio of standard deviation/average (coefficient of variation) ＞0.15 were screened,and their expression patterns were revealed based on Short Time-series Expression Miner (STEM).Then,the functional enrichment analysis of time-series genes in each group was performed using DAVID,and the genes enriched in the top ten functional categories were extracted to detect their expression patterns.Different time-series genes were identified in the three groups,and most of them were enriched in the ribosome and oxidative phosphorylation pathways.Time-series genes in the three treatment groups had different expression patterns and functions.Time-series genes in the ATO group (e.g.CCNA2 and DAB2)were significantly associated with cell adhesion,those in the AMN107 group were related to cellular carbohydrate metabolic process,while those in the ATO+AMN107 group (e.g.AP2M1) were significantly related to cell proliferation and antigen processing.In imatinib-resistant CML cells,ATO could influence genes related to cell adhesion,AMN107 might affect genes involved in cellular carbohydrate metabolism,and the combination therapy might regulate genes involved in cell proliferation.

Objective: To investigate the value of the trigeminocervical response (TCR) for revealing bulbar involvement in patients with spinal and bulbar muscular atrophy (SBMA). Methods: Thirty patients with SBMA and 30 healthy male controls were included in this study. In all of the normal controls, stimulation of the infraorbital nerve on one side produced bilateral short latency waves consisting of a positive/negative wave, p19/n31, the mean latency of which was measured. The mean square root of the ratio between the amplitude of p19/n31 and the mean rectifi ed surface electromyography (EMG) activity preceding the stimulus, the A value, was estimated. The parameters of the TCR were compared between the two groups. Results: Among the patients with SBMA, 21 (70.0%) had delayed latencies of p19/n31 (P < 0.01) and all (100%) had reduced A values (P < 0.01) relative to the normal controls. Conclusions: All parameters of the TCR were signifi cantly different between the patients with SBMA and the normal controls. T

Objective To discuss the clinical application of different particle size of grain fat sieved by the homogenizing fat extractor.Methods A lot of 68 patients in this group were women,and the average age was 28 years.With the aid of tumescent technique,anterior and lateral thigh fat granules were extracted using liposuction needle;after the homogenizing fat extractor and sieve purification,fat particles were obtained with uniform particle size and no fibrous tissue for different sizes of 2.00 mm,0.90 mm,0.50 mm and 0.28 mm,respectively.After choosing corresponding diameter of fat transplantation needle and appropriate injection level according to fat particle size,the multiple spot and multiple track tunnels,multi-level injection for the facial soft tissue deficiency or cavity were then carried out.With long-term postoperative follow-up,evaluation of different grades were given for the complication,fat survival rate and satisfaction.Results The results were followed up for 3-12 months postoperatively;as responding,the facial appearance of graft field deformity or deficiency was significantly improved and the skin of the recipient area was soft;wrinkles was relieved,and so that they appeared young plump well-pleasing appearance.And there were no complications,such as infection,hematoma,fat liquefaction,pigmentation,induration and so on.Satisfactory results were obtained.Conclusions The treatment of facial soft tissue deficiency or deficiency,by choosing corresponding diameter of fat transplantation needle and appropriate injection level according to the differences of fat particle size sieved by the homogenizing fat extractor,can acheive a high fat survival rate,and stable long-term effect.Thus,this safe and ideal method for rejuvenation of facial treatment is worth promoting.

Objective To investigate the morbidity of anomalous coronary origin from the opposite coronary sinus, which may cause sudden death of young athletes in Chinese population.And to identify the imaging characteristics of this anomaly and its clinical significance combined with literature review.Methods The computed tomographic coronary angiography (CTCA) database at TEDA International Cardiovascular Hospital was reviewed.All of the patients diagnosed with isolated anomalous origin of a coronary artery from the opposite sinus of valsalva (anomalous origin of coronary artery, AOCA) and subsequent coursing between the pulmonary artery and the aorta were collected from 14 343 Chinese individuals.The location of anomalous coronary origin, the shape and course of the proximal ectopic arterial segments were identified.The nonatherosclerostic stenotic caliber of the segments and the angle between the ectopic coronary artery and the adjacent aortic wall were assessed.Results Seventy-four patients of AOCA (including the left or right single coronary artery) were diagnosed using CTCA.Among the 74 cases, the potentially serious course of the ectopic coronary artery between the pulmonary artery and the aorta were identified in 59 individuals.Fifty-six cases of ectopic right coronary with interarterial course (anomalous origin of right coronary artery, AORCA) and three patients with anomalous origin of the left coronary artery (AOLCA) were found, including two cases judged as potentially serious origin of either single left coronary artery (n=1) or single right coronary artery (n=1).The morbidity of the potentially serious anomalous origin of coronary artery in Chinese population was established as 4.1‰ (59/14 343).In the subgroup of AORCA, the lumen of initial ectopic segment was frequently compressed and stenotic.In 29 cases (52.7%) the stenosis of the lumen were more than 50%, and in 3 cases (5.4%) the stenosis of the ectopic coronary artery were more than 70%.The incidence of AORCA was 17.7 times higher (56/3) than that of AOLCA in Chinese population.Conclusions Nowadays CTCA is considered the most useful imaging technique in identifying the origin, shape and course of ectopic initial segment of the coronary artery.The significance of these anatomic characteristics, that may induce sudden death in Chinese young athletes, need to be investigated further.

Objective To evaluate the value of CTA in assessing congenital heart disease and related heterotaxy syndrome.Methods A total of 20 patients with congenital heart disease and heterotexy syndrome underwent CTA and 3-dimensional reconstructions.And intracardiac and extracardiac abnormalities were assessed.Results Three cases were left isomerism,two of which were bi-lobed left lungs and trilobed right lungs,and another one was bi-lobed lungs.The most common associated cardiovascular anomalies included single ventricle (n=2),atrial septal defect (n=2),ventricular septal defect (n=1),transposition of the great arteries (n=2),pulmonary artery stenosis (n=2),atresia (n=1),persistent left superior vena (n=1),no hepatic segment of inferior vena cava (n=1).The rest 17 cases were right isomerism.All of them were trilobed lungs.Associated cardiovascular anomalies included single ventricle (n=9),double outlet of right ventricle (n=2),endocardial cushion defect (n=6),atrial septal defect (n=10),patent foramen ovale (n=1),ventricular septal defect (n =8),transposition of the great arteries (n =14),pulmonary artery stenosis (n =16),atresia (n =1),pulmonary venous drainage (n=6),persistent left superior vena (n=7),no hepatic segment of inferior vena cava (n=2).Conclusion CTA can clearly show the structure of heart,great vessels,chest and abdomen which is a useful tool to accurately assess congenital heart disease and related heterotaxy syndrome for medical or surgical management.

Objective To establish the method of contact heat evoked potential(CHEP)and to explore the value of this evoked potential in pain testing of patients with cerebral infarction.Methods A total of 100 healthy volunteers and 30 patients were examined.The healthy volunteers were divided into 3 groups according to the length of their arms:(Group A:56.0～65.0 cm ;Group B :65.5～74.0 cm ;Group C :74.5～83.0 cm).A recently de- veloped heat-foil technique with a rapid temperature rising rate at 70℃/s was used to elicit pain and contact heat e- voked potentials.Contact heat was delivered via one circular thermode(diameter 27 mm,area 573 mm~2)and set at two intensity levels(49.5℃and 54.5℃)to three body sites:the thenar eminence,the dorsum of hand and proximal volar forearm.The subjects were asked to rate the pain with numerical rating scale after each stimulus and CHEP was recorded from Cz and Pz.The association between stimulus intensities and pain rating was explored,the main compo- nents of the evuked potential were watched.CHEP,sensory conduction velocity(SCV)and somatosensory evoked potentials(SEP)were performed in patients with hemi-anesthesia caused by cerebral infarction.Results The pain intensity ratings were 3.2?0.3 and 4.4?0.5 at thenar eminence,5.0?0.7 and 6.3?0.8 at the dorsum of hand and 5.3?0.6 and 7.2?0.5 at the proximal volar forearm when the temperature of 49.5℃and 54.5℃was applied, respectively;Three components,Cz/N550,Cz/P750 and Pz/P1000,were identified in the evoked potentials.Cz/ N550 and Cz/P750 appeared when the dorsum of hand and proximal volar forearm were stimulated.In contrast,Pz/ P1000 could be identified when nociceptors of thenar eminence and proximal volar fbrearm were excited.In the pa- tients with cerebral infarction,CHEP disappeared or became abnormal on one side,while SCV and SEP were normal on that side.Conclusion It was suggested that CHEP could be elicited reliably in the controls.CHEP is helpful in the assessment of analgesia in patients with cerebral infarction.
