ABSTRACT
<p><b>OBJECTIVE</b>To observe the efficacy of auricular point sticking therapy for abnormal blink in children and the impact on the breakup time of tear film.</p><p><b>METHODS</b>A total of 123 cases (246 eyes) with abnormal blink were randomly assigned into two groups, 62 cases (124 eyes) to an observation group, 61 cases (122 eyes) to a control group. The observation group received auricular point sticking therapy with western medicine; the treatment was given 6 d per week; the next day received no treatment and changed dressing. The auricular points were yan (LO), pingjianqian (TG), pingjianhou (AT), gan (CO), pi (CO), wei (CO). The western medicine pateints took 1 oral multivitamins tablets per day, and received sodium hyaluronate eye drops and tobramycin eye drops in turn, 3 times per day, 7 day as a course; treatment was lasting 3 courses. Patients in the control group only received western medicine. The blink frequency score and breakup time of tear film of children were observed, the curative effect of the two groups was compared.</p><p><b>RESULTS</b>After treatment, the blink frequency score was lower significantly (<0.01), and lower significantly in subjects in the observation group compared to those in the control group (<0.01). After treatment, less than 10 s were 51 eyes (41.8%) and greater than 10 s (including 10 s) were 71 eyes (58.2%) in the 122 eyes from the control group; in the observation group, less than 10 s were 13 eyes (10.5%) and greater than 10 s (including 10 s) were 111 eyes (89.5%); there was significant difference between the two groups (<0.01). The effective rate of the observation group was 91.9% (114/124), which was higher than the control group 65.6% (80/122); the difference was statistically significant (<0.01).</p><p><b>CONCLUSION</b>The efficacy of auricular point sticking therapy combine western medicine is better in treating children with abnormal blink compared to western medicine by reducing the breakup time of tear film. This suggests that reduction of tear film stability is one of the main reasons which causes frequent eye blink, and breakup time of tear film can be used as the testing standard.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To explore the differences in the clinical therapeutic effects on xerophthalmia of and deficiency between the needling technique (the combined reinforcing technique to induce warm sensation) and the reinforcing needing technique achieved by rotating needle.</p><p><b>METHODS</b>A total of 54 patients of xerophthalmia were randomized into an observation group (28 cases) and a control group (26 cases). In both of the groups, the main acupoints included Cuanzu (BL 2), Sizhukong (TE 23), Taiyang (EX-HN 5) and Fengchi (GB 20); the combined acupoints were Danzhong (CV 17), Sanyinjiao (SP 6), Taixi (KI 3) and Taichong (LR 3). In the observation group, the needling technique was used and in the control group, the reinforcing needing technique achieved by rotating needle was adopted. The treatment was given once every day. 10 treatments made one course and 2 courses were required. Before and after treatment, the score of eye symptoms, tear secretion and the breakup time of tear film were observed in the two groups. The clinical therapeutic effects were compared between the two groups after treatment and in 4-week follow-up after treatment separately.</p><p><b>RESULTS</b>After treatment, the total effective rate was 92.9% (26/28) in the observation group and was 80.8% (21/26) in the control group, without significant difference in comparison (>0.05). In 4-week follow-up after treatment, the total effective rate was 85.7% (24/28) in the observation group and was 61.5% (16/26) in the control group, indicating the significant difference in comparison (<0.05). After treatment, the differences were significant in the score of eye symptoms, tear secretion and the breakup time of tear film as compared with those before treatment in the two groups (all <0.01). After treatment, the improvements of the score of eye symptoms, tear secretion and the breakup time of tear film in the observation group were better remarkably than those in the control group, indicating the significant differences (all <0.05).</p><p><b>CONCLUSION</b>The needling technique achieves the significant therapeutic effects on xerophthalmia of and deficiency and the recurrence rate of the disease is low.</p>
ABSTRACT
Background The effectiveness of medical tissue adhesive for the reparation of operative incision has been recognized,but its influence to ocular surface microenvironment is not quite clear.Objective This study was to appraise the safety and efficacy of α-cyanoacrylate,a medical issue adhesive,for the reparation of the conjunctival and skin laceration.Methods Twenty healthy New Zealand rabbits were randomly divided into suturing group and medical glue group.Routine ophthalmic examination,the level of tear secretion and breakup time of tear film (BUT) were tested before operation.The upper bulbar conjunctiva of each right eye was cut apart about 1.0 cm after surface anesthesia and the skin of back was incised about 2.5 cm length after local anesthesia.The conjunctival and skin lacerations were adhered with compound medical adhesive in the medical glue group,and continuous suture was done to repair the conjunctival laceration and interrupted suture to the skin laceration with 5-0 chorda serica chirurgicalis in the suture group.The routine ophthalmic examination,level of tear secretion,BUT and the states of wound healing were examined 1 day,2 days and 7 days postoperatively.Pathologic examination of the corresponding tissues was also carried out 1 week after the animals were sacrificed.The data were analyzed by SPSS 13.0 statistical software.This experiment followed the Administration of the Care and Use of Experimental Animals of Shanghai City.Results The conjunctival and skin lacerations healed well both in the suture group and the medical glue group.The levels of tear secretion 1 day and 2 days postoperatively in the medical glue group were (12.70±2.21)mm and (12.70±2.00)mm respectively,showing a significant lowness in comparison with (14.90±2.38)mm and (14.90±2.33)mm of the suture group (q =-4.02,P =0.03;q =-4.02,P =0.03).Compared with the baseline,the difference of the levels of tear secretion in the medical glue group was not statistically significant in various time points after operation (P=1.00,1.00,0.51).The BUT values at 2 days and 7 days postoperatively in the medical glue group were (4.50 ± 1.18) seconds and (4.10±0.88) seconds respectively,being significantly longer than (3.30 ± 1.06) seconds and (3.00±1.25) seconds in the suture group (q=4.37,P=0.02;q=4.19,P=0.03).Compared with the baseline,there was not statistically significant difference at each time point postoperatively in the medical glue group (P =0.28,0.59,0.21).However,BUT at each time point after operation in the suture group was significantly shorter than that of the baseline (P=0.01,0.01,0.00).Pathological examination showed that all the conjunctival and skin lacerations healed well.Trivial collagen hyperplasy was seen in the eyes of the suture group and infiltration of a few of inflammatory cells was found in the medical glue group.In the pathological result of the skin test,there was conspicuous scar and severe collagen hyperplasy in the suture group,but in the medical glue group,the skin structure was almost normal.Conclusions α-Cyanoacrylate is safe and effective for the repair of the conjunctival incision with little affection to ocular surface microenvironment.
