Objective To evaluate the imaging quality and diagnostic value of different MR sequences for abnormalities of knee cartilage. Methods Three sequences of MR, including double echo steady state (DESS), multi echo data imagine combination (MEDIC) and true fast imaging with steady state precession (TrueFISP) were performed in 18 healthy volunteers. Signal-to-noise ratio (SNR) of knee cartilage and contrast-to-noise ratio (CNR) to surrounding tissues were measured and compared. Results SNR of cartilage was the highest in MEDIC sequence imaging, CNR of cartilage-synovia was the highest in DESS sequence imaging among three sequences (P<0.05). Conclusion Compared with the other sequences, DESS seems to be optimal in diagnosis of abnormalities in knee cartilage.

Objective:To analyze the reasons for the failure of scleral buckling (SB) in the treatment of rhegmatogenous retinal detachment, and observe the efficacy and safety of re-buckling.Methods:This was a retrospective non-comparative clinical research. From July 2014 to June 2020, patients with first-time SB failure who visited the Beijing Tongren Hospital were included in this study. There were 42 patients, including 30 males and 12 females, with the average age of 29.40±16.13 years, and they were all monocular. The retinal detachment range <1, 1-2 and > 2 quadrants were 9, 22 and 11 eyes, respectively. The macula was involved in 38 eyes. The average logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity (BCVA) was 0.99±0.57. Forty eyes and 2 eyes were performed 1 and 2 SB, and all the retina were not reattached. All patients were under general anesthesia, according to the conditions during the operation, re-freeze and located the holes under indirect ophthalmoscope. And selected the new external pressure material or retained the old one in combination with the other operations to reattaced the retina. The average follow-up time was 31.93±18.97 months. The reasons for the failure of the first surgery based on the records of this surgery were analyzed. The visual acuity changes, the rate of retinal reattachment and the occurrence of complications were observed. The visual changes were compared by paired t test. Results:The top three reasons for the failure were: 16 case of the displacement of the compression spine (38.10%); 9 cases of missing the retinal holes and 9 case of improper selection of compression substances (account for 21.43%, respectively); 6 cases of insufficient height of compression spine (14.29%). All of retina were reattached (100%, 42/42). The average logMAR BCVA was 0.52±0.40. The difference of logMAR BCVA between before and after surgery was statistically significant ( t=6.106, P=0.000). There were a slight increase in intraocular pressure in 8 eyes, the average intraocular pressure was 25.00±2.61 mmHg (1 mmHg=0.133 kPa). No serious complications occurred after surgery. Conclusions:The position deviation of the compression spine, the missed hole during the operation, the improper selection of external compression material, and the insufficient height of the compression spine are the main reasons for the failure of SB. After adjusting the reasons for the failure, there is still a higher rate of retinal reattachment.

ObjectiveTo study the relationship between carotid sclerosis and lipoprotein (LP) (a) in patients with coronary artery disease. MethodsOne hundred and fifty-nine coronary artery disease patients with coronary arteriongraphy (CAG) positive were selected as the study group, and Gensini points were taken in these patients. Forty CAG normal patients was in control group, and all of them were examined with ultrasound, and serum levels of LP (a) were tested. According to ultrasound, study group were divided into 4 subgroups: normal intima group(24 cases), mild stenosis group(41 cases), moderate stenosis group (82 cases) and severe stenosis group ( 12 cases). ResultsThe rate of carotid sclerosis in study group [84.9％ (135/159)] was significantly higher than that in control group [42.5％ ( 17/40 )] (P ＜ 0.01 ). Gensini points in moderate and severe stenosis group were significantly higher than those in normal intima and mild stenosis group (P ＜ 0.05 or ＜ 0.01 ), Gensini points in severe stenosis group were significantly higher than those in moderately group(P ＜ 0.01 ), but there was no significant difference between mild stenosis group and normal intima group(P ＞ 0.05 ). The level of LP(a) in study group[(35.27 + 23.38) mg/L] was significantly higher than that in control group[(23.13 ± 16.56) mg/L](P＜ 0.01 ). The level of LP(a) in mild stenosis group was significantly lower than that in moderate and severe stenosis group(P＜ 0.05 or ＜ 0.01 ), and there was no significantly difference compared with that in normal intima group(P＞ 0.05 ). ConclusionsCarotid sclerosis ultrasonic testing helps to predict the risk degree of coronary artery disease. The level of LP(a ) is closely related with carotid sclerosis and has important value in judging the condition of patients with coronary artery disease.

BACKGROUND:Regional myocardial diastolic dysfunction has been recognized as a sensitive and characteristic sign of myocardial ischemia and infarction,train rate imaging(SRI)is a novel ultrasonic technique with good spatial and high temporal resolution,nd it can be used to quantitatively analyze regional myocardial function.OBJECTIVE:To investigate the characteristics of the longitudinal diastolic strain rate(SR)in ischemic and infarct myocardium by SRI,n order to explore the clinical value of SRI in evaluating regional left ventricular diastolic dysfunction in patients with coronary artery disease.DESIGN:A case-control study.SETTING:Department of Cardiology.Second Affiliated Hospital of Sun Yat-Sen University.PARTICIPANTS:All the participants were selected from outpatients and/or inpatients of the Second Affiliated Hospital of Sun Yat-sen University between October 2005 and April 2006.Twenty-one patients with myocardial infarction(MI group)and 11 patients with angina pectoris(AP group)were enrolled in the study.Twenty age-matched healthy subjects served as controls.METHODS:After performing conventional echocardiographic examination,olor tissue Doppler images from apical four-,three- and two-chamber views (posterior septum and lateral wall,nterior septum and posterior wall,nterior and inferior wall)were recorded on magneto-optical disk.Then SR curves were derived from the stored images off-line using QLAB 4.2software.MAIN OUTCOME MEASURES:Ischemic segments in the AP group,nfarct segments in the MI group and normal segments in the control group were analyzed.The parameters measured included peak early diastolic SR (SRe)and peak late diastolic SR(SRa).RESULTS:Compared with the normal myocardium,oth SRe and SRa decreased significantly in the infarct and ischemic myocardium(all P＜0.05).No significant differences were observed with respect to SRe and SRa between the infarct and ischemic myocardium(both P＞0.05).CONCLUSION:SRI can be used to quantitatively analyze regional myocardial diastolic dysfunction in patients with coronary artery disease,ut its value is limited in differentiating infarct from ischemic myocardium.

BACKGROUND: Psychological behaviors play an important role in children accidental injury, and children with a tendency of accidental injury display specific psychological properties in characters and behaviors.OBJECTIVE: To investigate the difference of personality and behavioral characters between normal children and children with a tendency of accidental injury.DESIGN: Case controlled analysis based on suffered children and normal hildren.SETTING: Department of pediatric in a civic hospital.PARTICIPANTS: Totally 131 accidental injured children aged from 7 to 11 years were admitted at Tengzhou Civic center hospital between January and December 2001. Those with congenital intellectual disturbance and brain trauma were excluded and the rest 89 cases were asked to fill questionnaire, 8 were removed from the study due to unintegrated data and 81pieces of integral data were collected (reclaiming rate of 91.01%), including 50 males and 31 females with the mean age of (8.59±1.86) years, the intelligence quotient was(96±15) determined by Peabody picture vocabulary test(PPVT); and 81 children in control group matched in age and sex were selected from healthy children of school age without injury history and similar in some aspects, such as parents' culture degree, economic condition, educational state and the economic and culture state of inhabitancy with control group, including 45 males and 36 females with the mean age of (8.92±1.73) years, the intelligence quotient was(98±18) by PPVT. Two groups were matched in sex, age and IQ(P＞0.05).METHODS: Eysenck personality questionnaire and Achenback children behavioral rating scale(parents rating scale) were used.RESULTS: Data of two groups with 81 questionnaires in each entered into the final analysis without loss. ① Scores for psychoticisim, introverted and extroverted character and neurological quality in Esonk personality question naire were(50. 01±10.58, 55.19±12.1, 57.35±10.12) in injury group, higher than corresponding(45.63±13.81, 48.09±6.49, 50. 01±10.39)in control group( t = 2. 27-4.65, P＜0.05) . Scores for modified rating scale was(49.42±10.42) in control group, higher than(39.65±13.03)in injury group( P＜0.001); ② The median was found higher in hyperactivity, aggression, violation of discipline, bad communication, split anxiety,depression and physical complaint in boys of injury group; as well as in hyperactivity, cruelty, aggression, depression, physical complaint, social retreat, violation of law in girls of injury group, comparing to control group(P＜0.001); ③ Positive behavioral detecting rate of injury group was 32.09% (26/81), higher than 11.11% (9/81) of control group(P ＜0.001), OR was 3.78, and 95% CI was 1.66-8.59. Behavioral factors was proved of lower sensitivity(32. 1% ) with specificity of 88.9% and higher prognostic value of 74. 3%; ④ The mean score for Achenback children behavioral rating scale was(39. 84±10. 99) in boy which was obviously higher than(34.26 ± 10.43) in girls of injury group( P ＜0.05). The edian for violation of discipline and aggression in boys and depression in girls were significantly higher than the opposite sex group(P＜0.05 or 0.01) . The mean score for Achenback children behavioral rating scale was (37.62±11.03) in injury group, which were obviously higher than (17.77±12.12) of control group( P＜0.01) . ⑤Results of multiple factors Logistic analysis revealed that the risk factors for accidental injury included: aggression, hyperactivity and iolation of discipline in boys and aggression, violation of discipline and depression in girls.CONCLUSION: Children with a tendency of accidental injury has obvious ehavioral problems, behavioral factors were proved of lower sensitivity, but of igher specific positive prognostic value. Both boys and girls displayed speific characters in aggression and violation of discipline, and lack of pretendng capability comparing to normal children, thereby liable to response in on-rational manner.

Objective To detect the presence of DEK protein in the tissue and voided urine of patients with bladder urothelial carcinoma ,and an?alyze the relationship between DEK protein and clinical pathological classification of bladder cancer. Methods The expression of DEK protein was examined by immunohistochemistry in 48 bladder cancer tissues and 18 adjacent normal tissues(control group). The presence of DEK protein in voided urine was analyzed by western blot in 28 bladder cancer patients and 6 healthy individuals(control group). Results The positive ex?pression of DEK protein in bladder tumor tissues(73%)is higher than in adjacent normal tissues(33%,P<0.05). The expression of DEK in su?perficial bladder cancer(86%)was found higher than invasive bladder cancer(55%)with significant differences(P<0.05). The expression of DEK in urine samples of bladder cancer patients(0.834)was found higher than control group(0.242,P<0.05);Compared with the DEK expres?sion of control group,the sensitivity of diagnosis of bladder cancer with voided urine could be 82.1%. Conclusion DEK protein positive ex?pressed in tissues and voided urine of patients with bladder urothelial carcinoma. The expression was correlated with pathological classification of bladder cancer. The positive rate of DEK expression in early stage of tumor tissues is higher than late stage. The presence of DEK protein in tissues and voided urine can be considered as a suitable biomarker for bladder cancer potentially.

Objective:To study the expression of IFN-γ,IL-4 and IL-17 in peripheral blood of patients with oral lichen planus(OLP). Methods:The level of IFN-γ,IL-4 and IL-17 in peripheral blood were detected by ELISA in 60 OLP patients(including 30 erosive ca-ses and 30 non-erosive cases)and 25 healthy volunteers(controls).Data were statistically analyzed by SPSS 13.0.Results:(1 )The level of IFN-γin serum of patients with non-erosive OLP and erosive OLP were significantly lower than that in the controls(P<0.01);while the level of IL-4 in the patients were significantly higher than that in the controls(P<0.01),and the IFN-γ/IL-4 ratio in non-ero-sive OLP and erosive groups were significantly lower than that in the control group(P<0.01);(2)The level of IL-17 in erosive OLP pa-tients was significantly higher than that in the controls(P<0.05),while no statistical difference was seen between non-erosive OLP group and the control group(P>0.05).Conclusion:The down-regulated level of IFN-γand up-regulated level of IL-4,which result in the decrease of IFN-γ/IL-4 ratio,might be one of the immune etiological factors of OLP,while the up-regulated level of IL-17 protein in OLP may be mainly related with the inflammatory processes of OLP.
