To compare the clinical effect of phacoemulsification and middle incision extracapsular cataract extraction ( Ml-ECCE) . METHODS: One hundred and eighty - five eyes of phacoemulsification (137 cases) and 185 eyes of 139 cases for Ml-ECCE from January 2011 to May 2013 were involved in this study. And the ratio posterior capsular rupture during surgery, visual acuity, corneal edema, corneal astigmatism and intraocular pressure post operation were followed up.RESULTS: On 1d after surgery, uncorrected visual acuity in the group of Ml-ECCE was better than that of phacoemulsification group, while from 3d; 1 and 3mo after surgery, no significant difference was found from the above two groups. On 1d postoperation, corneal edema ratio in phacoemulsification group ( 45 eyes ) was higher than that in Ml-ECCE group(20 eyes) ( X2=11. 665, P=0. 0006 ) . No significant difference was found for the ratio of posterior capsule rupture during surgery in these two surgical technique groups(X2=0. 094,P=0. 759). On 1wk;1 and 3mo after surgery, significant difference was found for the average of surgical induced corneal astigmatism between two groups (u=6. 661, 6. 880, 4. 187, P = 0. 00, respectively ). During following up, no significant difference was found for the intraocular pressure between two groups ( u=1. 858, 0. 963, 0. 471, 1. 349, 1. 388; P= 0. 063, 0. 335, 0. 638, 0. 177, 0. 165). lntraocular pressure on 1d postoperation in phacoemulsification and Ml-ECCE groups was higher than before operation ( u = 19. 86, 19. 39, P = 0. 00, respectively). And on 1wk; 1 and 3mo postoperation, intraocular pressure in the operated eyes in both groups was lower than before operation for 2~3mmHg.CONCLUSlON: Although phacoemulsification and Ml-ECCE could both get good visual rehabilitation, with similar visual outcome, no significant effect for intraocular pressure, and no severe complications, the latter one owns the advantage that easier maneuver, quicker recovery, and cheaper instruments needed, which is suitable for the hard nuclei cataract in local hospitals. Ml-ECCE is a safe, effective and easy manipulation for local hospital for large batch of cataract surgeries.

Objective: To investigate the relationship between 24-hour ambulatory pulse pressure (24hPP), 24-hour ambulatory pulse pressure index (24hPPI), night-time ambulatory pulse pressure index (NPPI) and coronary artery disease (CAD) occurrence in hypertension patients. Methods: A total of 305 subjects received ambulatory blood pressure monitoring (ABPM) in our hospital from 2016-05 to 2016-07 were enrolled. Base on ABPM information, 24hPP, 24hPPI and NPPI were calculated to analyze their relationship to CAD occurrence. 24hPP was defined by 24-hour mean systolic blood pressure (24hSBP) minus 24hDBP, 24hPPI by the ratio of 24hPP/24hSBP and NPPI by the ratio of night (22:00-6:00) PP/SBP. Results: There were 222/305 (72.8%) subjects with hypertension. Compared with normotension subjects, hypertension patients had increased 24hPP: (49.0±11.6) mmHg vs (42.2±7.4) mmHg, P<0.001, 24hPPI: (0.39±0.06) vs (0.37±0.05), P=0.004 and NPPI: (0.40±0.07) vs. (0.38±0.06), P=0.009 respectively. 116/222 (52.3%) hypertension patients suffered from CAD. Compared with non-CAD patients, CAD patients presented elevated 24hPP: (50.9±12.2) mmHg vs (47.0±10.6) mmHg, P=0.013, 24hPPI: (0.41±0.07) vs. (0.38±0.06), P<0.001 and NPPI: (0.42±0.07) vs. (0.38±0.06), P<0.001 respectively. Among 83/305 (27.2%) normotension subjects, the above indexes were similar between CAD patients and non-CAD subjects. Logistic regression analysis demonstrated that with adjusted age, gender, body mass index (BMI) and antihypertensive medication, 24hPPI [OR=1.95, 95% CI 1.11-3.44, P=0.020] and NPPI [OR=2.21, 95% CI 1.28-3.82, P<0.01] were related to CAD occurrence. ROC curve analysis showed that 24hPPI and NPPI were superior to 24hPP for CAD screening and prediction in hypertension patients. Conclusion: 24hPPI and NPPI were closely related to CAD occurrence in hypertension patients, they were both helpful for CAD screening and prediction in hypertension patients.

Objective To assess the effects of zinc protoporphyrin (ZnPP), an inhibitor of the heme oxygenase (HO), on the colonic interstitial cells of Cajal (ICC) of diabetic rats with colonic slow transit. Methods Diabetes mellitus (DM) model was induced by intraperitoneal injection of streptozotocin (STZ) in Sprague-Dawley rats. Twenty four successfully established DM rats were selected, and 16 healthy rats were served as controls. Six weeks later, gastrointestional (GI) dysfunction was observed by charcoal propulsion experiment in 8 DM rats and 8 controls. The rest rats in DM group were divided into 2 groups: DM rats intraperitoneal injected with PBS (n=8) or with 10 μmol/kg of ZnPP (n = 8) every other day for 3 weeks. The rats in control group (n = 8) were intraperitoneally injected with PBS. The levels of HO and c-kit (the special receptor of ICC) expression were detected by Western blotting. The distribution of ICC was observed by immunohistochemistry and the area of c-kit positive cells was counted. Results The GI propulsion rate in DM rats interfered with PBS was significantly declined compared to that in the controls (63.0%± 1.2% vs 71.8%±2.0%, P<0.05). But it was improved in DM rats interfered with ZnPP (72.5± 2.6%, P<0.05), which showed no significant differentee with that in control group (P>0.05). The expression of HO-1 in close and distant colon of DM rats interfered with ZnPP was decreased (P< 0.05). The expression of HO-2 in close colon and the area of c-kit positive cells of DM rats interfered with PBS was reduced compared with that in controls (P<0.05), but both were improved in DM rats interfered with ZnPP (P<0. 05). Conclusion Administration of ZnPP might be able to protect ICC by its blockage of HO-1 in DM rats with gastrointestinal dysfunction.
