Abstract?AIM: To evaluate the clinical application of IOL Master by comparing with traditional ultrasound biometry on the accuracy and characteristics of intraocular lens calculation.?METHODS:Data was analyzed from 164 patients ( 206 eyes ) with age - related cataracts who underwent phacoemulsification and intraocular lens ( IOL ) implantation in our hospital from June 2014 to June 2015. Before surgery, axial length and corneal curvature were measured with IOL Master and combined application of ultrasonic or manual keratometry, respectively. Phacoemulsification and foldable lens implantation were done in the patients. IOL power calculation was carried out using the SRK-Ⅱformula with the basis of IOL Master data. The visual acuity and refractive outcome were followed-up for 3mo postoperatively.?RESULTS:There was a significant difference between the two methods on axial length measurement which was 23. 86 ± 1. 05mm by IOL Master and 23. 50 ± 0. 83mm by ultrasound ( P = 0. 025 ). There was also a significant difference between the two methods on corneal curvature measurement which was 44. 18 ± 1. 35D by IOL Master and 43. 70 ± 1. 41D by keratometry ( P = 0. 01 ). The mean absolute error(MAE), at 3mo after operation, was 0. 41± 0. 30D and 0. 93 ± 1. 10D by the IOL Master and ultrasound groups, respectively, there was a significant difference between the two methods(P=0. 027).?CONCLUSION:The IOL Master is a non-contact, safe,easy-to-do and patient-friendly methods for axial length and corneal curvature measurement with high accuracy, thus it can calculate the IOL power more accurate and improve the predictive value for postoperative refraction.

Chinese Pharmacological Bulletin 2019;35(8):1104-1109
Aim To determine the role of Wnt/β-catenin/TCF7L2 pathway in diabetic cardiomyopathy.Methods A model of type 1 diabetes mellitus was established by intraperitoneal injection of streptozotocin(STZ)into 7 or 8-week old C57BL/6 mice.After four weeks, the diabetic animals were divided into three groups with seven to eight in each:diabetes mellitus(DM), diabetes injected with β-catenin inhibitor iCRT14(2.5, 5 mg·kg-1).After continuous intrap-eritoneal administration for 8 weeks, heart samples were stained with HE and examined under light microscopy.Expressions and distributions of β-catenin and TCF7L2 in myocardium were detected by immunohistochemistry.Protein levels of β-catenin, Tcf7l2 were detected by Western blot.mRNA levels of β-catenin, Tcf7l2, Nppa and c-Myc were detected by qPCR.Results The myocardial cells in DM were relatively disordered and the size of the nucleus was irregular.Western blot and immunohistochemistry data showed that the expressions of β-catenin and TCF7L2 in heart with DM increased, while those in nucleus of the cardiomyocytes significantly increased.qPCR showed that the mRNA expression of β-catenin downstream target c-Myc and cardiac hypertrophy marker Nppa were up-regulated.After injection of eight weeks with different iCRT14 doses, the cardiomyocytes were relatively regular; the protein levels of β-catenin and TCF7L2 decreased, and their expressions in nucleus decreased as well; the mRNA levels of Nppa and c-Myc markedly decreased.Conclusions Activation of canonical Wnt/β-catenin/TCF7L2 signaling pathway plays a pivotal role in diabetic cardiomyopathy; iCRT14 significantly improves the phenotype of cardiomyopathy in type 1 diabetic mice.

Objective To investigate the potential clinical factors associated with the prognosis and relapse of adult onset Still's disease(AOSD).Methods The factors possibly influencing the prognosis and relapse of AOSD were analyzed by logistic regression and COX regression in the cohort study.Ninety-six con- secutive inpatients of AOSD diagnosed based on Yamaguchi criteria in the hospital from March 1996 to September 2004 were included in the study.Results Nine cases(9.4%)were lost during the follow-up. Eleven patients(12.6%)were diagnosed as other diseases(5 with other rheumatic diseases,4 with tumor and 2 with infections)in the 87 follow-up cases.In 76 cases,3 patients(3.9%)died and 33 patients(43.4%) got remission over one year after treatment.Splenomegaly(OR=3.14,95%CI=1.01~9.74)and treated with methotrexate(OR=0.22,95%CI=0.07~0.67)were associated with the prognosis from the logistic regression analysis of the 76 cases.The serum ferritin(RR=I.05,95%CI=1.01~1.08)and treated with methotrexate (RR=0.13,95%CI=0.02~0.76)were associated with relapse from the COX regression analysis of the 61 remis- sion cases.Conclusion We need to be very cautious in the follow-up of AOSD patients because some of them may change to other diseases.Methotrexate may be an importent therapy of AOSD not only in improve- ment the prognosis but also in reduction of relapse.

OBJECTIVETo observe the intervention of Shenkangling Decoction (SD) on the renal injury of primary nephrotic syndrome (PNS) children patients of Shen deficiency blood stasis syndrome (SDBSS) and to explore its mechanism.
METHODSTotally 65 PNS children patients were randomly assigned to the combined group (33 cases, treated by SD +Western medicine) and the Western medicine group (32 cases, treated by Western medicine). Meanwhile, 30 healthy children were recruited as the healthy control group from the medical examination center. Those in the Western medicine group were treated with prednisone (5 mg per tablet) at the daily dose of 1.5 -2.0 mg/kg till two weeks after their urine protein turned to negative. Then the dosage was reduced once daily per every other day. The therapeutic course lasted for more than 1 year. For those with no effect of prednisone or partial effect, cyclophosphamide intravenous pulse therapy was additionally applied for 2 successive days per week, a total of 6 times, or they took cyclosporine A. Patients in the combined group additionally took SD while starting treatment of prednisone. SD was decocted in water for oral dose, once daily, taken in two portions until 2 months after prednisone was discontinued. Efficacy was evaluated based on serum levels of chemotactic factor CXCL16, disintegrin metalloproteinase 10 ( ADAM10 ), disintegrin metalloproteinase 17 (ADAM17), albumin (ALB), total cholesterol (TC), and 24-h urine protein excretion (UPE) detected by ELISA before and after treatment.
RESULTSCompared with before treatment in the same group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE were significantly lower in the two treatment groups (P <0. 01). Compared with the control group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly increased, and the serum ALB level decreased in the two treatment groups (P <0.01). Compared with the Western medicine group at the same time point, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly decreased in the combined group. The 1 -year recurrence rate and the recurrence times decreased in the combined group (P <0.01). The complete remission rate increased in the combined group (P <0.01).
CONCLUSIONSD could effectively improve the clinical prognosis of PNS children patients possibly by reducing the release of inflammatory mediators such as CXCL16, ADAM10, and ADAM17, decreasing UPE and the TC level, and elevating the serum ALB level.

Objective To study the significance of alteration of concentration of endothelins(ET) and calcitonin gene related protein(CGRP) in bile in patients with acute choiangitis of severe type(ACST). Methods The concentration of ET and CGRP were detected by radioimmunoassay in 55 cases of ACST at openation time, and 7th, 14th day after operation. Results Compared with the control group, the concentration of ET in bile in patients with ACST was significantly higher at operation time(P<0.01~0.001). The concentration of ET in bile also showed significant difference at operation time between the 2 groups with different ACST severity(P<0.05). The concentration of ET in bile gradually reduced after operations. Compared with the control group, the concentration of CGRP in bile was signficantly lower at operation time(P<0.01). CGRP in bile gradually rose after operation. Conclusions The ET in bile has some effect on the ACST pathologic alterations. The content of ET in bile is related to the severity of ACST. The disturbance of the balance between bile ET and CGRP may contribute to the pathologic process of liver and bile duct injury in ACST.

postprandial/preprandial power ratio, percentage of normal gastric slow wave,percentage of slow gastric slow wave and percentage of tachycardia gastric slow wave.Measurement data with normal distritution were presented as x ± s, and measurement data with skew distritution were presented as M (Qn).The postoperative time and pre-and post-prandial electrogastrograms were compared by the repeated measures two-way ANOVA.The comparison between groups were evaluated with the LSD test and analysis of variance.Results Thirty patients were screened for eligibility with a mean age of 62 years (range, 49-75 years), including 26 males and 4 females.The pre-and post-prandial main frequencies were changed from 2.83 ± 0.13 and 3.01 ± 0.17 before operation to 2.66 ± 0.10 and 2.82 ± 0.10 at postoperative day 30 with coherent changing trend.The main frequencies at postoperative each time points were significantly lower than those before operation while postprandial above indicators were higher than preprandial those, showing a significant increasing trend with the passage of postoperative time (F =285.62, P < 0.05).There was no interaction between the time and meal (F =0.22, P > 0.05).The pre-and post-prandial coefficients of dominant frequency instablility were changed from 0.133 ±0.031 and 0.045 ±0.019 before operation to 0.150 ±0.043 and 0.115 ±0.010 at postoperative day 30 with coherent changing trend, and coefficients of dominant frequency instablility at postoperative each time points were significantly higher than those before operation while postprandial above indicators were lower than preprandial those, showing a significant reducing trend with the passage of postoperative time (F =16.51, P < 0.05).The pre-and post-prandial main powers were changed from (85 ± 15) μV and (149 ± 23) μV before operation to (74 ± 9) μμV and (98 ± 10) μV at postoperative day 30, and main powers at postoperative each time points were significantly lower than those before operation, showing a significant increasing trend with the passage of postoperative time (F =48.45, P < 0.05).There was interaction between the time and meal (F =7.39, P < 0.05).The postprandial/preprandial power ratio was changed from 3.00 ± 0.35 before operation to 2.52 ± 0.25 at postoperative day 30, and postprandial/preprandial power ratios at postoperative each time points were significantly lower than those before operation, showing a significant increasing trend with the passage of postoperative time (F =26.66, P < 0.05).The pre-and post-prandial percentages of normal gastric slow wave were changed from 81% ± 6% and 94% ± 5% before operation to 57% ± 5% and 70% ± 5% at postoperative day 30 with coherent changing trend, and percentages of normal gastric slow wave at postoperative each time points were significantly lower than those before operation while postprandial above indicators was lower than preprandial those, showing a significant increasing trend with the passage of postoperative time (F =49.36,P <0.05).There was no interaction between the time and meal (F =0.24, P > 0.05).The pre-and postprandial percentages of slow gastric slow wave were changed from 17% ± 7% and 4% ± 4% before operation to 32%±4% and 21%±4% at postoperative day 30 with coherent changing trend, and percentages of slow gastric slow wave at postoperative each time points were significantly higher than those before operation while preprandial above indicators were higher than postprandial those, showing a significant reducing trend with the passage of postoperative time (F =46.54, P < 0.05).There was interaction between the time and meal (F =18.12, P < 0.05).The pre-and post-prandial tachycardia gastric slow wave percentages were changed from 1.55% (1.04%,2.21%) and 1.95% (1.74%, 4.22%) before operation to 8.97% (5.76%, 12.02%) and 12.41% (8.04%,16.85%) at postoperative day 30 without completely coherent changing trend, and percentages of tachycardia gastric slow wave at postoperative each time points were significantly higher than those before operation while postprandial above indicators were higher than preprandial those, showing a significant difference between before operation and postoperative day 3 (Z =11.47, 13.28, P < 0.05) and no significant difference among the postoperative day 7, 11, 30 (Z =1.88, 0.31, 0.03, P > 0.05).There was no interaction between the time and meal (F=0.85, P<0.05).Conclusions After the esophagectomy, gastric electrical activity of thoracic (tube) stomach is also retained before and after the meal.There are significant differences among the main frequency, main power, coefficients of dominant frequency instablility, postprandial/preprandial power ratio,percentage of normal gastric slow wave, percentage of slow gastric slow wave, percentage of tachycardia gastric slow wave of thoracis (tube) stomach, they have changed dynamically in the perioperative period.
