    ObjectiveTo study the clinical effect of the combination of glucosamine hydrochloride with exercise therapy and traditional Chinese medicine hot compress in the treatment of early patellofemoral osteoarthritis. MethodsA total of 126 patients with early patellofemoral osteoarthritis treated between June 2013 and April 2015 were divided into group A (n=43), B (n=42) and C (n=41) with the method of random number table. Oral administration of glucosamine hydrochloride tablets, exercise therapy of knee joints and traditional Chinese medicine hot compress were applied for the 43 patients in group A. Oral administration of glucosamine hydrochloride tablets and exercise therapy of knee joints were applied for the 42 patients in group B. Exercise therapy of knee joints and traditional Chinese medicine hot compress were applied for the 41 patients in group C. Chen's Scoring was applied before the treatment and 2, 4, 12 and 24 weeks after the treatment. ResultsThe differences of Chen's scores at the time points after treatment and those before treatment of the same group had statistical significance (P<0.05). The differences of Chen's scores at the time points after treatment in group A and those in group B and C had statistical significance (P<0.05). There were no obvious adverse effects due to administration of glucosamine hydrochloride tablets in group A and B. Five patients in group A and 4 patients in group C suffered from the symptoms of local erythema, light cutaneous pruritus and other contact dermatitis after traditional Chinese medicine hot compress. Those symptoms disappeared automatically several hours later without any special treatment. ConclusionThe treatment of early patellofemoral osteoarthritis by the combination of glucosamine hydrochloride tablets with exercise therapy and traditional Chinese medicine hot compress can rapidly relieve joint pain, and maintain efficacy for a long time.

  • The efficacy of intravitreal conbercept for macular edema secondary to retinal vein occlusion

    ObjectiveTo investigate the effects of intravitreous injection of conbercept for macular edema secondary to retina1vein occlusion(RVO) during 6 months period. MethodsA retrospective clinical study. 34 patients (34 eyes) were included in this study,who were diagnosed with macular edema due to retinal vein occlusion by ophthalmologic examination, fundus photography, optical coherence tomography (OCT), fundus fluorescein angiography and other methods. The best corrected visual acuity (BCVA) was examined using the international standard visual acuity chart, and the results were converted to the logMAR visual acuity. The average logMAR BCVA was 0.90±0.68, and the mean macular central retinal thickness (CMT) was (672.27±227.51) μm before treatment. All subjects received intravitreal injection of 0.5 mg conbercept (0.05 ml) at the first visit. Injections were repeated based on the visual acuity changes and the OCT findings. 34 eyes received 69 times of injection, the average number of injections was 2.03±1.03. BCVA, OCT were examined before and after treatment using the same method. BCVA and CMT changes, drugs and treatments associated cardiac and cerebral vascular accident, intraocular pressure elevation, retinal tears, retinal detachment, endophthalmitis and other complications after treatment were observed. Linear correlation analysis was used to analyze the correlation between prognosis BCVA and baseline BCVA, correlation between prognosis BCVA and baseline CMT, and also correlation between BCVA and CMT at different time points before and after treatment. ResultsAt 1 week and 1, 2,3, 6 months after treatment, the average logMAR BCVA was 0.65±0.61, 0.56±0.61, 0.46±0.55, 0.56±0.71, 0.44±0.48 respectively. During 1, 2, 3, 6 months after treatment, the mean logMAR BCVA were improved with statistically significant difference (Z=34.029, 47.294, 41.338, 43.603;P < 0.05), while 1 week after treatment showed no obvious improvement (Z=21.941,P > 0.05). At 1 week and 1, 2, 3, 6 months after treatment, the average CMT was (285.89±96.69), (256.65±143.39), (278.68±156.92), (290.11±188.17), (217.15±48.04) μm respectively. At 1 week and 1,2,3,6 months after treatment, the mean CMT were all decreased with statistically significant difference (Z=68.500, 98.735, 93.235, 91.132, 109.162; P < 0.05). There was a positive correlation between the prognosis visual acuity and preoperative visual acuity (r=0.682,P < 0.05). However,there was no correlation between the prognosis vision and the degree of macular edema before treatment (r=0.078,P > 0.05). Before and 3, 6 months after treatment, BCVA was negatively correlated with CMT (r=0.491, 0.416, 0.386; P < 0.05), while there was no correlation in other time points (r=0.145, 0.217, 0.177; P > 0.05). Systemic adverse reactions and persistent intraocular pressure elevation, iatrogenic cataract, retinal detachment, retinal tear, endophthalmitis and ocular complications were never found in the follow-up period. ConclusionIntravitreal conbercept is a safe and effective approach for RVO,which can significantly improve visual acuity and reduce CMT.

  • Foveal contour as a significant predictor of surgical outcome in idiopathic epiretinal membrane

    ObjectiveTo observe the foveal contour characteristic of idiopathic epiretinal membrane (iERM). MethodsA total of 53 eyes in 52 patients with iERM who underwent pars plana vitrectomy with epiretinal membrane and inner limiting membrane peeling were enrolled in this retrospective study. All eyes received the examination of optical coherence tomography (OCT) and minimum resolution angle in logarithmic (logMAR) best corrected visual acuity (BCVA). Foveal contour grading was according to the ratio of central macular thickness (CMT) to the thickness of the retina 1 mm away on OCT line scan: Grade 0, depressed; Grade 1, flat; Grade 2, elevated. Baseline foveal contour grade was as follows: 28 eyes with Grade 1 (Group 1), and 25 eyes with Grade 2 (Group 2). The mean logMAR BCVA was 0.40±0.26 in Group 1, and 0.60±0.27 in Group 2 respectively. The mean CMT was (433.52±133.05) μm and (571.70±85.40) μm respectively. The logMAR BCVA and CMT both demonstrated significant difference between the two groups (t=-2.825, -4.512; P<0.05). OCT images and BCVA at 1, 3 months after surgery were collected and analyzed. The change in foveal contour, BCVA and CMT were evaluated. The relationship between surgical outcome and different preoperative grading was analyzed. ResultsFoveal contour grade at 3 months after surgery was as follows: 15 eyes with Grade 0, 21 eyes with Grade 1, and 17 eyes with Grade 2, demonstrating significant difference compared with baseline (Z=-3.588, P<0.05). In Group 1, there were 12 eyes with Grade 0, 10 eyes with Grade 1, and 6 eyes with Grade 2 postoperatively. In Group 2, there were 3 eyes with Grade 0, 11 eyes with Grade 1, and 11 eyes with Grade 2 postoperatively. The postoperative foveal contour grade was significantly different between the two groups (Z=-2.466, P<0.05). The logMAR BCVA at 1, 3 months after surgery both improved significantly compared with baseline (P<0.05) in Group 1 (t=-3.226, -5.439) and Group 2 (t=-4.137,-5.919). The logMAR BCVA at 1, 3 months after surgery demonstrated significant difference between the two groups (t=-2.231, -2.291; P<0.05). The CMT decreased significantly at 1, 3 months after surgery in Group 1 (t=-2.674, -4.090) and Group 2 (t=-9.663, -9.865) compared with baseline (P<0.05). The CMT at 1, 3 months after surgery demonstrated significant difference between the two groups (t=-2.825, -3.003; P<0.05). The improvement of logMAR BCVA 3 months after surgery was negatively correlated (P<0.05) with preoperative logMAR BCVA (r=-0.758) and preoperative CMT (r=-0.359). ConclusionIn iERM eyes, flat foveal contour had better surgical prognosis than elevated ones.

  • Short-term efficacy of posterior sub-tenon injection of triamcinolone acetonide in macular edema due to ischemic retinal vein occlusions

    ObjectiveTo observe the short-term efficacy of posterior sub-tenon injection of triamcinolone acetonide (PSTA) in the treatment of macular edema due to ischemic retinal vein occlusions (RVO). MethodsA retrospective clinical study. A total of 53 eyes of 53 patients with RVO macular edema diagnosed by fundus color photography, fundus fluorescein angiography and optical coherence tomography (OCT) were included in the study. The best corrected visual acuity (BCVA) was detected by the international standard visual acuity chart, and the results were converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. The central macular thickness (CMT) was measured by OCT. Among 53 eyes, there were 27 eyes with ischemic RVO macular edema (ischemic group) and 26 eyes with non-ischemic RVO macular edema (non-ischemic group). The mean logMAR BCVA was 0.82±0.37, mean CMT was (662.1±216.7) μm in ischemic group. The mean logMAR BCVA was 0.41±0.23, mean CMT was (548.0±161.9) μm. The differences of logMAR BCVA and CMT between the two groups were both statistically significant (t=4.745, 2.258; P<0.05). All eyes were treated with a single sub-Tenon injection of 0.4 ml triamcinolone acetonide suspension (100 mg/ml).The mean logMAR BCVA, CMT before and 1, 3 months after the treatment between the two groups were observed and compared. ResultsOn 1 and 3 months after treatment, the mean logMAR BCVA in the non-ischemic group (0.32±0.25 and 0.27±0.29) were improved compared with ischemic group (0.76±0.37 and 0.41±0.79), the difference was statistically significant (t=5.052, 5.240; P<0.05). The mean logMAR BCVA before and after treatment had no statistically significant difference in ischemic group (F=0.516, P>0.05), but had a statistically significant difference in non-ischemic group (F=7.685, P<0.05). On 1 and 3 months after treatment, the mean CMT in the ischemic group were (534.7±223.4), (470.8±234.7) μm, which were lower (127.4±28.28), (191.4±34.55) μm before treatment. In the non-ischemic group, the average CMT was (426.2±188.8), (371.3±200.6) μm, which were lower (103.1±33.1), (164.9±49.6) μm. There were statistically significant differences in the mean CMT between the ischemic group and the non-ischemic group (F=17.040, 10.360; P<0.05). In non-ischemic group, CMT had a bigger reduction compared to the the ischemic group (t=2.056, 2.103; P<0.05). The difference of CMT decrease value between two groups was not statistically significant (t=0.560, 0.441; P>0.05). On 1 month after the treatment, there were 3 and 5 eyes had a higher intraocular pressure than 21 mmHg (1 mmHg=0.133 kPa) in ischemic and non-ischemic group, respectively; but all of them returned to normal after drug treatment. There were no drugs and ocular injection related complications. ConclusionPSTA of ischemic RVO macular edema can lower the CMT in the short term, but can't significant improve the visual acuity.
