Objective:To investigate the efficacy of gastrodin injection combined with dexamethasone in the treatment of sudden deafness and its effect on hemorheology and hearing.Methods:Eighty patients with sudden deafness who received treatment in the Department of Otolaryngology, General Hospital of Taiyuan Iron and Steel (Group) Co., Ltd., from August 2018 to March 2020 were included in this study. These patients were randomly assigned to receive either intratympanic injection of dexamethasone (control group, n = 40) or intratympanic injection of dexamethasone combined with gastrodin injection (treatment group, n = 40). Total effective rate was compared between the two groups. The auditory threshold at 0.5, 1.0, 2 and 4 kHz was measured in each group. Before and after treatment, plasma viscosity, low shear whole blood viscosity, fibrinogen and erythrocyte deformability index were compared between the two groups. Drug-related adverse reactions were recorded in each group. Results:Total effective rate in the treatment group was significantly higher than that in the control group [92.50% (37/40) vs. 75.00% (30/40), χ2 = 4.401, P < 0.05]. After treatment, the auditory threshold at 0.5, 1.0, 2 and 4 kHz was significantly decreased compared with before treatment in each group (all P < 0.001). After treatment, the auditory threshold at 0.5, 1.0, 2 and 4 kHz was (42.71 ± 7.06) dB, (44.01 ± 9.35) dB, (48.06 ± 11.37) dB and (52.40 ± 14.26) dB, respectively, in the treatment group and (50.14 ± 8.09) dB, (53.70 ± 10.46) dB, (55.10 ± 13.47) dB and (59.26 ± 15.77) dB respectively in the control group. There were significant differences between the two groups ( t = 4.376, 4.368, 2.526 and 2.267, all P < 0.05). After treatment, plasma viscosity, low shear whole blood viscosity and fibrinogen in each group were significantly decreased (all P < 0.001). After treatment, erythrocyte deformability index in each group was significantly increased ( P < 0.001). After treatment, plasma viscosity, low shear whole blood viscosity and fibrinogen were significantly decreased, and erythrocyte deformability index was significantly increased, compared with before treatment in each group. After treatment, plasma viscosity, low shear whole blood viscosity and fibrinogen, and erythrocyte deformability index were (1.68 ± 0.39) mPa · s, (19.07 ± 3.65) mPa · s, (3.11 ± 0.58) g/L, (0.68 ± 0.08), respectively in the treatment group, and (2.01 ± 0.41) mPa · s, (22.10 ± 4.49) mPa · s, (3.89 ± 0.75) g/L, (0.60 ± 0.07) respectively in the control group. There were significant differences in plasma viscosity, low shear whole blood viscosity and fibrinogen, and erythrocyte deformability index between the two groups ( t = 3.688, 3.312, 5.203, 4.760, all P < 0.05). There was no significant difference in the incidence of adverse reactions between the treatment and control groups (10.00% vs. 15.00%, χ2 = 0.457, P > 0.05). Conclusion:Gastrodin injection combined with dexamethasone can enhance the curative effect on sudden deafness, effectively improve patient's hemorheology and hearing, and is highly safe.

AIM: To evaluate posterior capsular opacification (PCO) with hydrophobic acrylic intraocular lens (IOL, Sensar AR40e) and silicone IOLs after cataract surgery, to use a software program developed to provide an objective assessment of the amount of PCO in the digital images of the posterior capsule to quantify PCO. METHODS: Ninety-eight eyes underwent standardized phacoemulsification and "in the bag" IOL placement, were randomized to receive a three piece lens of hydrophobic acrylic or silicone, but lens materials were different in one case. In year 1 and 2, digitized retro-illumination images were taken from the posterior capsule. Images were analyzed by POCO software program, removing the Purkinje light reflexes, contrast enhancement, filtering to enhance low-density PCO. RESULTS: The percentage of PCO were 0.32±0.13 of hydrophobic acrylic IOLs in year 1, compared with 0.39±0.17 of silicone (P=0.37). In year 2, the percentage of PCO were 0.42±0.20 with hydrophobic acrylic IOLs and 0.34±0.18 with silicone IOLs (P=0.50). Of those patients with PCO in year 1 and 2, severity grades were 0.50±0.30 and 0.82±0.58 of hydrophobic acrylic cases, compared with 0.63±0.35 and 0.55±0.35 of patients with silicone IOLs (P=0.52,P=0.69) with no statistical significance.CONCLUSION: The POCO system is capable of producing an objective and repeatable measure of PCO that is relevant to assessing techniques of PCO prevention.

This study was aimed to exploreBi-Min-Gan (BMG) granules induced immune tolerance for allergic rhinitis cases through changes of Treg cells to achieve the goal of treatment. SD rats were used as experimental animal, which were divided into the blank group, model group and BMG granules group. Allergic rhinitis rat model was established. Intragastric administration of BMG granules was given. Levels of CD4+CD25+Foxp3+Treg and IL-4, IL-10, TGF-β1, IL-13 were detected with flow cytometry and ELISA assay. The results of flow cytometry showed that CD4+CD25+Foxp3+Treg decreased after the successful establishment of the model (P<0.05); but it increased after treatment of BMG granules (P<0.05) to reach the level of the normal blank group (P>0.05). ELISA showed the concentrations of IL-10 and TGF-β1 decreased significantly after the successful establishment of the model (P<0.0001); concentrations of IL-4 and IL-13 increased significantly (P<0.0001). While, after treatment of BMG granules, concentrations of IL-10 and TGF-β1 in blood rebound but did not reach the level of the normal blank group;concentrations of IL-4 and IL-13 in the blood decreased but did not reach the level of the normal blank group. It was concluded that BMG granules can upregulate the number of Treg cells in allergic rhinitis rat, increase the secretion of IL-10 and TGF-β1, inhibit Th2 cell activity, and reduce secretion of IL-4 and IL-13, so as to improve symptoms of allergic rhinitis.

Objective: By observing the differences in Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and visual analog scale (VAS) scores in moxibustion treatment for moderate-to-severe primary knee osteoarthritis (KOA) with moxa of different storage years (3-year moxa and 1-year moxa from Qichun, Huanggang City, Hubei Province, China) through a randomized clinical trial, to objectively evaluate the differences in therapeutic efficacy of moxibustion with moxa of different storage years. Methods: A total of 63 patients with moderate-to-severe KOA who met the inclusion criteria were randomized into moxibustion group 1 and moxibustion group 2 by central randomization method, with 32 cases in moxibustion group 1 and 31 cases in moxibustion group 2. Moxibustion group 1 was treated with moxa stored for 3 years, and moxibustion group 2 was treated with moxa stored for 1 year. Dubi (ST 35), Neixiyan (EX-LE 4) and Heding (EX-LE 2) were selected in both groups, and the treatment lasted 20 min per time, 3 times a week. The immediate efficacy was compared after 6 times of treatment, and long-term efficacy was compared at follow-up 4 weeks after the end of treatment. Results: During the treatment, there were 2 dropouts in moxibustion group 1, and 1 dropout in moxibustion group 2. The total effective rate in the two groups was 83.3% and 60.0%, respectively. Followed up at 4 weeks after the end of treatment, the total effective rate in the two groups was 80.0% and 66.7%, respectively. There were no statistical differences between the two groups (both P>0.05). After treatment and 4 weeks after the end of treatment, the WOMAC and VAS scores in both groups decreased significantly compared with those before treatment (all P<0.01); the scores of stiffness item of WOMAC in moxibustion group 1 were lower than those in moxibustion group 2 (both P<0.05); there were no statistical differences in the scores of pain item and dysfunction item of WOMAC, and VAS scores between the two groups (all P>0.05). Conclusion: Moxibustion with moxa of different storage years (stored for 3 years and 1 year) both can improve the pain, stiffness and motor function in patients with moderate-to-severe KOA. While moxa stored for 3 years has a better therapeutic efficacy in improving stiffness of the knee joint than that stored for 1 year.
