International Eye Science 2015;(5):875-879
?AlM: To observe the changes of corneal topography and astigmatism et al with various duration of closing eyes and sleep;and study the impact of closing eye and sleep causing physiological hypoxia on corneal topography.
? METHODS: Sixteen volunteers were selected ( 32 eyes), 22-33 (26. 19 ± 3. 95) years old, without refractive errors and other eye diseases, as well as never wearing corneal contact lens, including 10 male eyes and 22 female eyes. The main parameters received corneal simulation K value, corneal astigmatism, corneal irregular measure ( ClM ) and the shape factor ( SF ) by Zeiss corneal topographer. They were measured before and after closed eyes 10, 20, 30, 60, 120min; before sleep and after over 6h sleep, they were detected immediately as soon as they opened eyes after 10, 20, 60, 120min.
? RESULTS: During closing eyes, there were no statistical significance on the changes of corneal topography, corneal astigmatism, and SF. After opening eyes and over 6h sleep, there were no statistical significance on the changes of corneal topography, corneal astigmatism, ClM, and SF.
?CONCLUSlON:Closing eyes and sleep don’t injure the cornea substantially, so corneal topography and corneal astigmatism don’t mainly change.
4.Effect of Mingjing decoction with argon laser on plasma VEGF in patients with diabetic retinopathy
International Eye Science 2016;16(7):1249-1252
AIM: To investigate the effect and mechanism of Mingjing decoction combining with argon laser on the levels of plasma vascular endothelial growth factor (VEGF) in patients with diabetic retinopathy(DR).
METHODS:The 66 patients(118 eyes)with DR at Ⅲ ~ Ⅴstage were randomly divided into two groups (treatment group and control group). The control group (33 patients with 56 eyes ) was treated with argon laser, and the treatment group (33 patients with 62 eyes) was treated with mingjing decoction combining with argon laser, and a blank group(30 eyes) was set up. The levels of plasma VEGF were detected by enzyme linked immunosorbent assay (ELISA). The results of best corrected visual acuity and fundus fluorescein angiography(FFA) were analyzed, as well as detected glycosylated hemoglobin ( HbA1c), blood coagulation function and the function of liver and kidney.
RESULTS: Patients with DR had significantly risen plasma VEGF before treatment when compared with blank control group ( P < 0. 05 ). After 3mo of combined treatment, the levels of plasma VEGF significantly reduced and HbA1c decreased in patients treated with mingjing decoction and argon laser, there were statistically significant difference compared to control group ( P < 0. 05 ). In the treatment group, the best corrected visual acuity and FFA were significantly improved in patients treated with mingjing decoction combining with argon laser compared to patients treated with argon laser alone after 3mo of combined treatment. CONCLUSION: Mingjing decoction combining with argon laser for DR can effectively reduce the level of plasma VEGF, stabilize blood sugar levels, improve the function of retina, and delay DR progresses.
5.Clinical Observation of Acupuncture-moxibustion for Endometriosis
Shanghai Journal of Acupuncture and Moxibustion 2017;36(6):711-714
Objective To observe the clinical efficacy of acupuncture-moxibustion in treating endometriosis (EM). Method Fifty EM patients were randomized into two groups, 25 cases in each group. The treatment group was intervened by acupuncture-moxibustion, while the control group was intervened by oral administration of Mifepristone tablets. Abdominal pain, pelvic lump, and relevant indicators were observed before and after the treatment, and the therapeutic efficacies were compared.Result After 6-month treatment, symptoms including abdominal pain obviously subsided in the treatment group and the total effective rate was 92.0%, versus 52.0% in the control group, and the between-group difference was statistically significant (P<0.01). The pelvic lump size was significantly changed after the treatment in both groups (P<0.05), suggesting that the lump size became smaller in both groups after the treatment;there was a significant difference in comparing the pelvic lump size between the two groups after the treatment (P<0.05), indicating that the lump size was reduced more significantly in the acupuncture-moxibustion group. The level of serum CA125 changed significantly after the treatment in both groups (P<0.05), suggesting that serum CA125 dropped in both groups after the treatment; there was a significant difference in comparing the level of serum CA125 between the two groups after the treatment (P<0.05), indicating that serum CA125 dropped more significantly in the acupuncture-moxibustion group. A year later, there was a significant difference in comparing the relapse rate between the two groups (P<0.05), revealing that the relapse rate was significantly lower in the acupuncture-moxibustion group than in the medication group.Conclusion Acupuncture-moxibustion can produce a marked therapeutic efficacy in treating EM.
6.Effect of Liujunzi soup on allergic cough in remission stage and total inflammation of children
Chinese Journal of Biochemical Pharmaceutics 2017;37(9):91-93
Objective To evaluate the effect of Liujunzi soup on the total course of disease and inflammatory mediators in patients with remission of allergic cough. Methods Eighty six patients with allergic cough were enrolled in our hospital from April 2011 to April 2012. The patients were randomly divided into observation group (n = 43) and control group (n = 43). The control group was given basic western medicine treatment, the observation group in the control group on the basis of another treatment of six gentleman soup. The levels of inflammatory cytokines, pulmonary function and adverse reactions were compared between the two groups in clinical efficacy, hospitalization time, total course of disease, IL-2, TNF-α and IL-6. Results The total effective rate was 90.70% in the observation group was significantly higher than that in the control group (72.09%)( P<0.05). The duration of hospitalization (13.35 ± 3.24) d and the total course of disease (17.68 ± 4.53) d were significantly shorter than those in the control group (16.23 ±3.10) d, (20.35 ± 4.67) d (P<0.05). The levels of inflammatory factors and pulmonary function in the observation group were statistically significant compared with the control group (P<0.05). No adverse reactions occurred in both groups. Conclusion Liujunzi Decoction combined with western medicine can improve the level of inflammatory cytokines and lung function, shorten the length of hospital stay, the total course of disease and high safety, and have good clinical value.

8.Clinical outcomes of C3F8 and air tamponade after vitrectomy for the treatment of idiopathic macular hole
Chinese Journal of Ocular Fundus Diseases 2016;32(5):473-477
Objective To compare the clinical effect of C3F8 and air tamponade after vitrectomy for the treatment of idiopathic macular hole (IMH).Methods A total of 54 eyes of 54 patients with IMH that had undergone 23G pars plana vitrectomy with internal limiting membrane peeling were retrospectively studied.All patients received optical coherence tomography ()CT) examination and the best corrected visual acuity (BCVA).They were divided into 2 groups.26 eyes in group A were filled with air and 28 eyes in group B were filled with C3F8.In group A,6 eyes at stage Ⅱ,20 eyes at stage Ⅲ,the minimum diameter (Dmin) of macular hole in 14 eyes was less than 400 μm,and in the other eyes was larger than 400 μm.In group B,10 eyes at stage Ⅱ,18 eyes at stage Ⅲ,the Dmin of macular hole in 15 eyes was less than 400 μm,and in the other eyes was larger than 400 μm.The differences of age,course of the disease,BCVA,fundus diameter,Dmin,height,index,diameter of outer retina diameter (Dord) between the two groups were not significant (P>0.05).The basic data before surgery and the closure rate,BCVA,Dord 1 month after surgery between two groups were compared.Results At 1 month after surgery,the IMH closure rate was 100.0% in group A and 92.9% in group B,the difference between these two groups was not significant (P=0.491).The closure rate of eyes with Dmin<400 μm were both 100.0% in two groups,and the closure rate of eyes with Dmin>400 μm were 100.0% in group A and 84.6% in group B.There was no statistically significant differences between two groups (P =0.480).The mean BCVA of two groups were 0.35±0.22 and 0.33 ±0.16 respectively.The mean Dord were (782.2 ± 478.0) μm and(792.1 ± 432.7) μm respectively.All cases got better BCVA (t=-7.310,-10.506;P<0.01) and shorter Dord (t=6.704,7.770;P<0.01).But there was no statistically significant differences between groups 1 month after surgery in BCVA and Dord (t =0.381,0.800;P =0.705,0.937).Conclusion Air tamponade after vitrectomy has the same efficacy as C3 F8 tamponade in the treatment of IMH.
