Objective To investigate the diagnostic values of DCE-MRI quantitative evaluation of the activity of sacroiliac joints in ankylosing spondylitis.Methods Forty two patients (36 male and 6 female) with ankylosing spondylitis in our hospital were enrolled prospectively according to the standard of diagnostic criteria for ankylosing spondylitis revised in 1984.All of them were evaluated with the blood sedimentation,C-reactive protein and ankylosing spondylitis activity index (BASDAI).We divided the patients with ankylosing spondylitis into stationary phase group and active phase group.We analyzed each of the MRI images of the two patients groups using the extended Tofts model to determine the quantitative parameters of DCE-MRI,such as contrast transfer coefficient (Ktrans),reflux constant (Kep),extravascular extracellular volume fraction (Ve),plasma volume fraction (Vp).And then the differences of quantitative data between the two groups were compared.Spearman correlation analysis was performed between the parameters with statistically significant difference and BASDAI scores.Results Among the 42 patients,22 patients (18 male and 4 female) were in active phase group and the other 20 patients (18 male and 2 female) were in stationary phase group.Ktrans,Kep,Ve were (0.750± 1.130)/min,(1.008±0.732)/min,0.460± 1.735;(0.163±0.401)/min,(0.505 ± 0.902)/min,0.345 ±3.460 for active phase group and the stationary phase group,respectively.The results of the active phase group was significantly higher than the stationary phase group (Z=3.727,2.317,3.696,respectively;all P＜0.05).The Vp had no statistically significance for the active phase group (0.125 ± 0.310) and the stationary phase group (0.160 ± 0.329) (Z=1.209,P＞0.05).Strong correlations existed between Ktrans,Kep,Ve and BASDAI score,the correlation coefficients were 0.714,0.430,and 0.676 (P＜0.05).Conclusions Quantitative DCE-MRI parameters can evaluate the activity of the ankylosing spondylitis.Strong correlations exist between Ktrans,Kep,Ve and BASDAI score.

OBJECTIVE: To perform morphometric analysis of bilateral cochleae in all subjects based on computed 3-dimensional reconstruction tomographic data and assist the surgeon in diagnosing the inner ear abnormality or surgical strategies. METHOD: Two hundred normal developed cochleae from 100 patients were divided into 5 groups according to age. Morphometric analysis of bilateral cochleae was performed in all subjects by 3D reconstructions and 2D multiplanar reformation. The length and width of the cochlear base, the length within the cochlear base, the height of the cochlea, the angle between the first and second turn of the cochlea, and the cochlear orientation within the cranial base were measured and compared in different age, sex and bilateral groups. RESULT: The length of the cochlear base was (8.56 +/- 0.52)mm, the width was (6.63 +/- 0.56)mm, the length within the cochlear base was (7.33 +/- 10.56)mm, the height of the cochlea was (3.76 +/- 0.28)mm, and the angle between the first and second turn of the cochlea was (15.82 +/- 2.78)degrees. All index above did not change significantly in different aging, sex or side (P > 0. 05). Variability in the angle between the first and second turn of the cochlea was considerable, and a smaller angle (from the midsagittal line) was showed in the older age groups than the younger groups (P < 0.05). CONCLUSION 3D and 2D volume rendering enables us to evaluate the features of cochlear morphology and orientation that may assist the surgeon in diagnosing the inner ear abnormality or surgical strategies.

Objective:To study the influence of different dietary patterns in hypertension, and to provide references for establishing a healthy dietary pattern, improving the abnormal blood pressure, preventing the early hypertension and controlling the high blood pressure.Methods:Random cluster sampling was adopted to analyze the dietary,examine the physical situations,and measure the blood pressures among 1 394 residents of Han nationality and Korean nationality aged from 40 to 80 years old from 8 villages in Jinlin Province from 2010 to 2011.Factor analysis was used to establish the dietary patterns and to analyze the effects of different dietary patterns on the prevalence of hypertension.Results:The prevalence of hypertension of middle aged and elderly people in the rural areas of Jilin Province was 35.3%.4 dietary patterns were obtained through factor analysis,including salted product dietary pattern,alcohol dietary pattern,condiments dietary pattern and high protein dietary pattern.By multivariate Logistic regression analysis and adjustment of the age,the gender,the nationality,the education and the career background, alcohol dietary pattern was positively correlated with the occurrence of the hypertension (OR=1.43,95%CI 1.07-1.90).Conclusion:Alcohol dietary pattern is closely related to the hypertension. Long-time large amount of alcohol is a risk cause for high blood pressure. Reducing alcohol consumption and developing healthy diet habits can help to prevent hypertension.

To observe the effect of various doses of oil of Piper longum unsaponifiable matter (OPUM) to cholesterol gallstones in experimental mice. C57BL/6 mice (n = 60) were randomly divided into 6 groups: control group, model group, OPUM (15, 30 and 60 mg x kg(-1)) group and ursodeoxycholic acid (UDCA, 60 mg x kg(-1)) group, administered for 10 weeks. The level of serum lipid and liver function enzymes were tested. The gallbladder was removed and bile was obtained by centrifugation. Next, the levels of the bile total cholesterol (TC), phospholipid (PL) and bile acid (TBA) were measured. The indicators of lipid peroxidation were determined and cholesterol saturation index (CSI) was calculated. The liver histological changes were observed by HE staining. The results showed that serum TC, TG (triglycerides) and AST (aspartate transaminase) contents, gallbladder cholesterol crystallization and CSI increased significantly (P < 0.05). In addition, the activity of SOD decreased significantly and MDA content increased significantly in liver (P < 0.05). HE staining results showed that the hepatic cord disorder and intracellular lipid droplets increased significantly. All results indicate that lithogenic diet lead to the formation of cholesterol gallstones. In OPUM (30 and 60 mg x kg(-1)) group, serum TC, TG and AST content, gallbladder cholesterol crystallization and CSI decreased significantly, the activity of SOD increased significantly and MDA content decreased significantly. HE staining results showed that OPUM can improve the morphology of liver cell, reduce the degree of hepatic cord disorders and restore the cell morphology close to normal. The cause of OPUM prevents cholesterol gallstone formation maybe due to protect the integrity of the liver cells, lower CSI, and reduce cholesterol crystal formation and hence prevent cholesterol gallstone formation.

Objective:To establish a method to determine the contents of pantoprazole sodium bioadhesive tablets. Methods:An HPLC method was adopted. The determination was performed on a HYPERSIL ODS-2 (150 mm × 4. 6 mm, 5μm) column with mobile phase consisting of 0. 01 mol·L-1 dipotassium phosphate solution –methanol (60 ∶40) at the flow rate of 1. 0 ml·min-1 . The de-tection wavelength was set at 289 nm, the column temperature was maintained at 30 ℃ and the sample size was 20 μl. Results:The linear range of pantoprazole sodium was 1. 28-20. 60μg·ml-1,(r=0. 999 8) . The average recovery was 99. 52%(RSD=1. 43%, n=9). Conclusion:The method is simple, accurate and reliable, and can be used for determining the content of pantoprazole sodium bioadhesive tablets.

Objective To explore the symptomatic improvement of different achalasia (AC)subtypes after peroral endoscopic myotomy (POEM) procedure.Methods A total of 33 patients received POEM for the first time were enrolled.Patients were evaluated by high-resolution manometry (HRM)and subtyped by Chicago classification criteria.The total scores of symptoms were evaluated by Eckardt scale before and after POEM.Solid food dysphagia,liquid dysphagia,reflux and chest pain were scored by five-point Likert scales and compared by Wilcoxon paired test.Multiple linear regression analysis was performed to analyze key factors affecting the prognosis of symptoms.Results Among 33 AC patients,there were 20 females and the mean age was (44.0± 13.3) years.According to Chicago criteria,four patients had subtype Ⅰ AC,25 patients had subtype Ⅱ AC,and four patients with subtype Ⅲ achalasia.Before operation,the total Eckardt score was 7.5(6.3,10.0),which declined to 1.5 (1.0,3.0) after operation,and the difference was statistically significant (Z=-4.795,P ＜ 0.01).There was no statistically significant difference in the incidence of solid food/liquid dysphagia,reflux and chest pain among subtypies.Solid food dysphagia was the main symptom of each AC subtypes.POEM could improve all the symptoms of subtype Ⅱ AC except for chest pain.Before and after POEM,solid food dysphagia score was 16.0 (12.0,16.0) and 2.0 (1.0,12.0),liquid dysphagia score was 2.0 (0.0,5.0) and 0.0(0.0,0.0),reflux score was 9.0 (6.0,9.0) and 0.0 (0.0,1.0),respectively,and the differences were statistically significant (Z =-3.929,-3.470,1.841;all P＜ 0.01).The results of multiple linear regression analysis indicated that female and 4 s integrated relaxation pressure (4 s IRP) of 10 mL continuous swallows were positively correlated with symptom scores of solid food dysphagia (β 3.950,P=0.048;β=0.376,P=0.005);While 4 sIRP in solid food swallow was negatively correlated with symptom scores of solid food and liquid dysphagia (β=-0.244,P =0.008;β=-0.118,P =0.037).Conclusion For patients with AC,clinical symptoms could be significantly improved by single treatment of POEM,but there are certain differences in the symptomatic improvement among different subtypes.

Keratorefractive surgery changes the central corneal thickness (CCT) and corneal curvature, which could influence the Goldmann applanation tonometer (GAT) and non-contact tonometer (NCT) measurements of intraocular pressure (IOP), but not dynamic contour tonometer(DCT). During the procedure of LASIK, there is a transient rise of IOP, which increases the risks of optic nerve damage. Meanwhile, the presence of functioning filtering blebs may affect the choice and outcome of refractive surgery, or even becomes a contraindication of surgery. Steroids are typically used after keratorefractive surgery, which could lead to IOP elevation. Hence it is important to monitor IOP after LASIK and to be aware of inaccurate IOP readings due to corneal flap interface fluid. Treating patients with postoperative elevated IOP after keratorefractive surgery is similar to that for patients with glaucoma. This review will address the issues surrounding the safety, relevant complications and implications of keratorefractive surgeries on glaucoma and relevant diagnostic tests.

BackgroundMonocyte chemotactic protein-1 (MCP-1)plays an important role in the tumor,inflammation,diabetic retinopathy and other neovascular disease,but the expression and the role of MCP-1 in the oxygen induced retinopathy(OIR) model have rarely been reported. Objective This study was to investigate the expression of MCP-1 in the retina development of newborn mouse and in mouse models with OIR.Methods C57BL/6J newborn mice were divided into two groups and 60 mice in each group.Mice in OIR group were exposed to 75％ oxygen for 5 days and then to room air.All mice in normal control group exposed to room air only.Ten mice in each group were randomly chosen and sacrificed at postnatal 5,7,12,14,17,21 days.The expression of MCP-1 in mouse retina was detected with the method of immunohistoehemistry and reverse transcription polymerase chain reaction(RT-PCR).Results MCP-1 positive cells were seen in normal mouse retina.Up-regulation of MCP-1 positive cells was detected both in 12 days in normal control group and in 14 days in OIR group.MCP-1 mRNA was detected in mouse retina at 5 days,and a transient up-regulation of MCP-1 mRNA was observed in 12 days in normal control group.MCP-1 mRNA in OIR group significantly increased in 14 days in comparison with the normal control group( P =0.028,P =0.001 ). Conclusions Expression of MCP-1 is detectable in whole retinal development procession of mice.A transient up-regulation of MCP-1 expression is detected in the critical period of retinal vascular development in mice models with OIR,which is closely related to the retinal vascular development and progression of retinal new vessels.
