Objective To evaluate the distribution characteristics of left ventricular systolic dyssynchrony (LV-SD) in dilated cardiomyopathy (DCM) patients with chronic heart failure (CHF) and normal QRS wave width, by pulsed-wave Doppler tissue imaging (PW-DTI), and study its relation with left ventricular systolic function, ventricular remodeling, and functional mitral regurgitation (FMR). Methods The time to peak systolic velocity (Ts) in 12 left ventricular segments was evaluated by PW-DTI, from which the standard deviation (SD) of Ts in the 12 segments (Ts-SD) and maximum Ts difference (Ts-maxD) were calculated. Results Ts-SD and Ts-maxD in the 12 LV segments of the DCM patients with CHF were significantly higher than those of the healthy controls (P＜0.01). In DCM patients with CHF and normal QRS wave width, the incidence of LV-SD was 29.8% (14/47) and the inferior wall was the most frequent distribution site of contraction delay. Linear regression analysis revealed a negative correlation between Ts-SD, Ts-maxD, and left ventricular ejection fraction (LVEF) (P＜0.01), but a positive correlation between Ts-SD, Ts-maxD and left ventricular end-diastolic volume (LVEDV), lefe ventricular end-systolic volume (LVESV), New York Heart Association (NYHA) cardiac function, FMR (P＜0.01) in DCM patients with CHF. Conclusion LV-SD exists in DCM patients with normal QRS width. LV-SD aggravates the LV systolic function damage, which is closely associated with left ventricular remodeling. LV-SD may contribute to the FMR in DCM patients.

Objective To explore the changes of GRO-α and VEGF in the peritoneal fluid of women with endometriosis and their correlation. Methods The levels of GRO-α and VEGF were detected by enzyme linked immunosorbent assay ( ELISA ) method in 39 cases of endometriosis and 25 normal cases of without endometriosis. Results The levels of GRO-αand VEGF in the peritoneal fluid of EMs group were ( 108.77 ± 20. 58 ) pg/ml and ( 199. 67 ± 99. 26 ) pg/ml separately, and it was significantly higher than those in control group ( 71.07 ± 18. 96 ) pg/ml, ( 115.46 ± 32. 39 ) pg/ml. The differences were statically significant( P <0. 05). The level of GRO-α in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was sig-nificantly lower than that in stage Ⅲ and Ⅳ[(99.43 ± 16.05)pg/ml vs (117.65 ± 20.8)pg/ml, P <0. 05] , while the level of VEGF in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was significantly higher than that in stage Ⅲ and Ⅳ[(246. 89 ± 114. 34) pg/ml vs ( 152. 82 ± 54. 55 ) pg/ml, P < 0. 05] .There was positive correlation between the level of GRO-α and r-AFS ( r = 0. 439, P < 0. 05 ), but no cor-relation between the level of VEGF and r-AFS ( r = -0. 210, P >0.05). There was no correlation be-tween peritoneal fluid levels of GRO-α and VEGF in the EMs group ( r =-0. 05, P>0. 05). Conclusion Compared with control group, the levels of GRO-α and VEGF in peritoneal fluid of women with endome-triosis were significantly increased, which indicated that the increased GR0-α and VEGF secretion involved in the pathogenesis of this disease. There was correlation between the peritoneal fluid level of GRO-α and the degree of EMs.

AIM:To observe and compare clinical effects of coaxial 1. 8mm microincision phacoemulsification and 3. 2mm small incision phacoemulsification.
●METHODS:A total of 117 eyes of 85 patients with age-related cataract in our hospital were divided randomly into two groups:43 patients (59 eyes) in the coaxial 1. 8 mm microincision cataract surgery group ( C - MlCS ) , 42 patients (58 eyes) in the coaxial 3. 2 mm traditional small incision cataract surgery group (C-SlCS). A total of 117 eyes were received phacoemulsification with intraocular lens implantation. Uncorrected visual acuity was recorded preoperatively and postoperatively at 1, 7, 30 and 90d. The effective phacoemulsification time and average ultrasound energy were recorded in surgery. Corneal endothelial cell and corneal topography were recorded preoperatively and postoperatively at 90 d.
●RESULTS:Uncorrected visual acuity ( logMAR) was no overall statistical significance difference between C-MlCS group and C-SlCS group (P>0. 05), but was significant statistical difference in different time-point within both groups(P<0. 05). Uncorrected visual acuity in different time-point had nothing to do with corneal wound size in cataract surgery(P>0. 05). On the 1 day after surgery, uncorrected visual acuity was 0. 16±0. 11 in C-MlCS group and 0. 22±0. 18 in C-SlCS group(P<0. 05). AVE was (7. 00± 2.72)% in C-MlCS group and (6. 16±3. 16)% in C-SlCS group (P>0. 05). EPT was (3. 09±1. 61)s in C-MlCS group and (3. 20±1. 92)s in C-SlCS group (P>0. 05). At 90 d after surgery, corneal endothelial cell loss percentage was (5. 81±2. 28)% in C-MlCS group and (5. 69±2. 38)% in C-SlCS group (P>0.05), SlA was (0.35±0.11) Din C-MlCS group and (0. 61±0. 13) D in C-SlCS group (P<0. 05).
● CONCLUSION: Compared with coaxial 3. 2mm traditional small incision cataract surgery, 1. 8mm coaxial microincision cataract surgery can get earlier visual rehabilitation and significantly reduce SlA. The coaxial 1. 8mm microincision cataract surgery is safe, effective and deserves further clinical applications.

Objective To observe the effect of calycosin on cisplatin?induced inhibition of human gastric BGC823 cells. Methods BGC823 cells were treated with different drugs:saline,cisplatin,calycosin and cisplatin combined with calycosin. MTT assays were used to detect the prolif?eration rate of BGC823 cell. Then the protein level and RNA level of cyclin D1,CDK4 and CDK6 were detected by Western blotting and Real?time PCR. Results The proliferation inhibition rates of BGC823 cells treated with 20μg/mL cisplatin,10μg/mL meperoflavone,and combina?tion of the 2 drugs were 56.44%± 2.08%,9.52%± 2.77%and 74.44%± 0.82%,respectively. The inhibition rate of the combination of drugs was significantly higher than that of the single drug treatment group(P<0.05). In addition,we found that calycosin can significantly enhance the inhi?bition of Cyclin D1,CDK4 and CDK6 by cisplatin in protein level and RNA level. Conclusion Calycosin can significantly increase the inhibitory rate of cisplatin on BGC823 cell proliferation,and the combination of the two drugs can reduce the side effects of cisplatin.
