Background The novel dynamic biomechanical device Corvis ST can measure a variety of corneal deformation parameters and record the dynamic process of cornea deformation.Understanding various corneal deformation parameters is of important clinical significance for morphological and functional prediction for myopic eyes in corneal refractive surgery.However,the range and meaning of corneal deformation parameters in myopic eyes are still unknown.Objective This study was to establish the range of corneal defamation parameters by Corvis ST and explore its clinical significance in myopic eyes.Methods A descriptive study was designed under the approval of Ethic Committee of Tianjin Eye Hospital and informed consent of patients.This study protocol complied with Helsinki Declaration.Four hundred and seventy-seven eyes of 257 myopic patients who were going to receive corneal refractive surgery were included in Tianjin Eye Hospital from June 2014 to January 2015.The corneal deformation parameters including the first applanation time (1st A-time),first applanation lengh (1 st A-length),first applanation velocity (1 st A-velocity),second applanation time (2nd A-time),second applanation length (2nd A-length),second applanation velocity (2nd A-velocity),highest concavity time (HC-time),highest concavity deformation amplitude (HC-DA),highest concavity peak distance (HC-PD),highest concavity radius (HC-R),non-contact intraocular pressure (IOPnct) and the central corneal thickness (CCTst) were measured by Corvis ST.Corneal structural parameters including CCT and corneal curvature were measured by 3-D anterior segment analysis system (Pentacam),and corneal biomechanical parameters including corneal resistance factor (CRF),corneal hysteresis (CH),intraocular pressure mimic Goldmann (IOPg) and intraocular pressure of corneal compensation (IOPcc) were measured by Ocular Response Analyzer (ORA).The distributions of the data were tested with the Shapiro-Wilk test and 95％ confidence intervals (CI) were calculated.The correlations of the variables were evaluated by Pearson correlation coefficient and Spearman rank correlation coefficient.Multiple linear regression was used to analyze the changes of 1st A-time,2nd A-time and HC-DA with corneal morphology and biomechanical parameters.Resnlts Only 1st A-time,2ndA-time,HC-time,HC-DA,CCTst and IOPnct showed the normality distribution in corneal deformation parameters.The positive correlations were found between 1st A-time,1st A-length,2nd A-length,2nd A-velocity,HC-R with CCT (r=0.338,rs=0.129,rs=0.282,rs =0.374,r=0.306,all at P＜0.01),while 1st A-velocity,2nd A-time,HC-D and HC-PD showed the negative correlations with CCT (rs =-0.235,r=-0.130,r=-0.259,r=-0.226,all at P＜0.01).CRF and CH showed positive correlations with 1st A-time,2nd A-length,2nd A-velocity,HC-time,HC-R and negative correlations with HC-PD,△A-length (all at P＜0.05).1st A-time,2nd A-time and HC-DA changed with CRF and IOPcc with the regression formations of 1st A-time =6.185+0.066CRF+0.034IOPec (F=300.123,P =0.000),2nd A-time=23.397-0.074IOPec-0.044CRF (F=227.979,P=0.000) and HC-DA =1.523-0.017IOPcc-0.017CRF (F=152.662,P=0.000).The CCTst,IOPst and IOPnct values by Corvis ST were significantly lower than CCT by Pentacam ([548.23±26.31] μm,IOPg ([15.02±2.72]mmHg and ([16.02-±2.56]mmHg) by ORA respectively (t =11.00,2.919,6.815,all at P ＜ 0.01).Conclusions The corneal deformation parameters by Corvis ST can quantitatively describe corneal biomechanical properties in myopic eyes.Both IOP and the corneal steep curvature of the 3 mm center area (K2) affect the deformation response of cornea.The reliability of Corvis ST in the measurement of CCT and IOP remains to be further studied.

Objective To get a general idea of the knowing level of knowledge and policies related to voluntary blood donation among rural residents,and to explore factors influencing their willingness of voluntary blood donation.Methods Three natural villages were randomly chosen in the north,middle and south of Anhui province as the investigation sites in Jan.2008.Data were collected by interviewing the target people,as well as using a self-designed questionnaire.A total of 724 people were interviewed and 620 valid questionnaires were obtained,with an effective retrieval rate of 85.6%.Results The score of voluntary blood donation knowledge among rural residents was 19.26?3.987,and the score of relevant policy knowledge was 5.85?2.154.There were significant differences in knowledge of both voluntary blood donation and relevant policies among different age groups.Residents with different education levels also differed significantly in knowledge of relevant policies.Logistic analysis indicated that age,education and knowing level of relevant policies were the factors that had influence people's willingness of voluntary blood donation.Conclusion Knowing level of voluntary blood donation knowledge is high among rural residents while the policy knowledge level is low.Willingness of blood donation among the group of age 25 to 34 is obviously higher than that of the group of age 18 to 24;willingness of people with middle school education background is lower than illiterate people;the higher the knowledge level,the higher of people's willingness.

Objective To analyze the clinical manifestation, diagnosis and treatment of acute mesenteric vascular obliteration (AMVO). Methods 112 cases of AMVO were analyzed, including 20 cases admitted to our hospital from 1992 to 2004 and 92 cases reported by other hospitals. Results Abdominal pain, abdominal distension, nausea and vomiting, decrease or disappearance of bowel sound, elevation of white blood cell count were more frequent manifestations.Cardiovascular disease, portal vein stasis or hypercoagulation state were common findings in patients' history. The average misdiagnosis rate of AMVO in these 112 patients was 61.5%, with a misdiagnosis rate of 45.0% in 20 cases of our hospital. The average mortality rate of all these patients was 41.9%, with a mortality rate of 30.0% for 20 cases of our hospital. Conclusion The early clinical manifestation of AMVO lacks specificity, the misdiagnosis ratio and mortality rate are very high. Angiography should be done early to confirm the diagnosis and improve the therapeutic effect in the patients suspicions of having this ailment.

Hydrolysate of Area subcrenata (HA) was found to be effective in lowering the elevated SGPT level induced by carbon tetrachloride, thioacetamide (TAA) and pred-nisolone. In addition, HA was shown to shorten sodium pentobarbital sleeping time in both normal and carbon tetrachloride intoxicated mice. The results indicated that HA possessesa significantl protective action on liver injuries in mice.

Objective To explore the effect and mechanism of stent implantation on the quality of sexual activity in middle and old age male patients with exertional angina pectoris.Methods One hundred and seventy-two male patients with exertional angina pectoris were enrolled in this study,and they were divided into control group (94 patients) and percutaneous coronary intervention group (78 patients).The patients in control group were given routine pharmacotherapy and the patients in percutaneous coronary intervention group were given drug-eluting stent implantation and routine pharmacotherapy.The sexual activity function was evaluated by international index of erectile function (IIEF)-5 scale before treatment and 3 months after treatment.The times of sexual intercourse was added up.The evaluation of angina pectoris was performed by the grade of Canadian cardiovascular society (CCS).At the same time,the walking distance and heart rate were measured through 6-minute walking test.The left ventricular ejection fraction(LVEF) was detected by echocardiogram.Results After treatment for 3 months,the scores of IIEF-5,the degree of sexual satisfaction,the times of sexual intercourse and the grade of CCS in percutaneous coronary intervention group were significantly improved compared with those in control group [(20.58 ± 7.36) scores vs.(16.38 ± 6.35) scores,(4.32 ± 1.38) scores vs.(2.51 ± 1.89) scores,(6.3 ± 3.2) times/month vs.(3.5 ± 1.6) times/month,(1.10 ± 0.43) grades vs.(2.50 ± 1.1 0) grades] (P ＜ 0.05).The walking distance and heart rate after 6-minute walking test and LVEF in percutaneous coronary intervention group were significant improved compared with those in control group [(386 ± 82) m vs.(281 ± 86) m,(95 ± 18) times/minute vs.(122 ± 25) times/minute,(65.2 ± 11.2)％ vs.(55.6 ± 13.8)％] (P ＜ 0.05).Conclusions Stent implantation can significandy improve the quality of sexual activity in middle and old age male patients with exertional angina pectoris.The mechanisms are associated with the exercise capacity increasing and the frequency of angina pectoris attacks decreasing during sexual intercourse.
