Clinical Analysis of the Etiology of Optic Neuritis in Patients at Different Ages in China

Purpose:.To determine the etiology of optic neuritis in patients of different ages in China. Methods: Records of optic neuritis patients who were hospitalized in the Department of Neuro-ophthalmology, General PLA Hospital, Beijing, between January 1, 2011 and December 31, 2011 were retrospectively reviewed. Results:.A total of 132 patients were divided into three groups by age..The percentage of patients aged ≤16 years,.16-45 years and >45 years were 17.4% (23/132),.54.6% (72/132), and 28.0% (37/132) respectively. The distribution of etiologies differed significantly among the three groups(x2=23.2, P=0.026)..The percentage of idiopathic demyelinating optic neuritis was the highest in the 16-45 group (44.4%), and the proportion of neuromyelitis optica was the highest in the ≤16 years group. Infectious optic neuritis was more frequently seen in patients aged ≤16 years and >45 years. The source of infection was viral (n=2), nasosinusitis (n=1) and bacterial (n=1) in the ≤16 years group and neurosyphilis (n=3) and nasosinusitis (n=1) in the >45 years group. The percentage of paraneoplastic syndrome in the >45 years group was 8.11% (3/37). Conclusion:.The etiology of optic neuritis in patients at various ages differed significantly.

An acupuncture meta-analysis for optic atrophy Seven randomized,controlled trials

OBJECTIVE： To evaluate the efficacy and safety of acupuncture for optic atrophy. DATA SOURCES： A computer-based online search was conducted in Medline （1966-2008）, Embase （1986-2008）, the Cochrane Library （up to 2008）, Chinese Biomedical Literature Database （1975-2008）, China National Knowledge Infrastructure （1994-2008）, VIP Database （1989-2008）, Wanfang Database （1980-2008） and the National Research Register for ongoing trials. DATA SELECTION： Randomized, controlled trials addressing acupuncture treatment for patients with optic atrophy were included in this review. Inclusion criteria evaluated all forms of acupuncture therapy, such as filiform needle, electro-acupuncture, laser-acupuncture, acupressure, and auricular-acupuncture. Comparisons between acupuncture therapy and no treatment （blank） or placebo or Chinese medicine or Western medicine, as well as between acupuncture as an adjuvant and other treatments, were included. Exclusion criteria included studies comparing different forms of acupuncture therapy, different manipulations of acupuncture, and different acupuncture prescriptions, as well as non-randomized, controlled trials and animal studies. The domain-based evaluation criteria recommended by the guidelines in Chapter 8 of the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1 was used to assess quality of the included studies. According to the type of outcome index, measurement data as assessed by weighted mean difference or standardized mean difference and 95% confidence interval; numeration data was estimated by relative risk and 95% confidence interval. Heterogeneity was analyzed by Meta-analysis using RevMan 5.0 software. MAIN OUTCOME MEASURES： Improved visual acuity and visual field was sought between treatment and control groups in the included articles. RESULTS： Seven randomized, controlled trials were included after screening and application of inclusion and exclusion criteria. However, the studies were of low methodological quality and lacked comparisons between acupuncture and no treatment or placebo. Applying visual acuity as the outcome index, meta-analysis indicated： the effect of medicine combined with acupuncture was superior to the medicine alone （relative risk = 1.41, 95% confidence interval 1.14-1.70, P 〈 0.01 ）, the efficacy of acupuncture was better than medicine alone （relative risk =1.42, 95% confidence interval 1.14-1.77, P 〈 0.01 ）. Using visual field as the other outcome index, meta-analysis revealed： effectiveness of acupuncture or acupuncture in combination with medicine was superior to medicine alone （relative risk = 1.47, 95% confidence interval 1.27-1.69, P 〈 0.01 ）. The 7 included articles were incorporated in a sensitivity analysis, and the overall effect showed a significant difference （relative risk = 1.35, 95% confidence interval 1.16-1.56, P 〈 0.01）. Acupuncture was not associated with any adverse events in any of the studies. CONCLUSION： Acupuncture therapy was determined to be superior to medicine in terms of improved visual acuity and visual field. However, well-designed, randomized, controlled trials with adequate controls and scientific rigor are urgently needed.

Bilateral Optical Nerve Atrophy Secondary to Lateral Occipital Lobe Infarction

Purpose:To report a phenomenon of optical nerve atrophy secondary to lateral occipital lobe infarction. Methods:Two successive patients with unilateral occipital lobe infarction who experienced bilateral optical nerve atrophy during the follow-up underwent cranial imaging, fundus photography, and campimetry. Results:Each patient was diagnosed with occipital lobe infarction by cranial MRI. During the follow-up, a bilateral optic atrophy was revealed,and campimetry showed a right homonymous hemianopia of both eyes with concomitant macular division. Conclusion:Bilateral optic atrophy was related to occipital lobe infarction, and a possible explanation for the atrophy was transneuronal degeneration caused by occipital lobe infarction.

HOW TO TREAT OPTIC ATROPHY WITH ACUPUNCTURE ?

Optic atrophy results mostly from affection by exopathic wind pathogen, insufficiency of Qi and Xue(blood) or hyperactivity of the liver-yang. We choose Qiuhou(EX-HN 7), Jingming(BL1 ), Taiyang(EX-HN 5 ) and Fengchi(GB 20) as the main acupoints and combine other auxiliary points according to different syndromes. For example, Hegu(LI 4) and Waiguan(TE 5 ) are supplemented for affection by exopathic wind pathogen, Qihai(CV 6), Zusanli(ST 36), Xuehai(SP 10) and Guang-ming(GB 37) for insufficiency of Qi and Xue, and Guanshu(BL 18), Baihui(GV 20), Taixi(KI 3),Sanyinjiao(SP 6) and Guangming(GB 37) for hyperactivity of the liveryang. When Qiuhou(EX-HN 7), Jingming(BL 1 ) and Fenchi(GB 20) punctured, the need1ing direction, angle and depth should be controlled very appropriate for achieving good therapeutic effect.

OBSERVATION ON THE THERAPEUTIC EFFECT OF ACUPUNCTURE ON OPTIC ATROPHY(48 CASES)

48 cases of optic atrophy were treated with acupuncture. Qiuhou (EX-HN 7), Jing-ming (BL 1), Ganshu (BL 18), Pishu (BL 20), Fengchi (GB 20), Cuanzhu (BL 2), Yiming (EX-HN 14), Guangming (GB 37), Taiyang (EX-HN 5), Yanglao (SI 6), Sibai (ST 2), Tongziliao(GB 1) were selected as main points, of which three to five points were punctured each time, but thefirst two were used necessarily. According to an overall differentiation of symptoms and signs auxiliarypoints were supplemented. The treatment was given once everyday with the manipulations of twirlingneedles plus slow or rapid insertion for reinforcing or reducing to make the needling sensation reach theeye regions. Twelve treatments made a course with an interval of 3 days between the two courses. Itwas shown that 15 cases were markedly effective (3l. 25 % ), 26 improved (54. 17% ), and 7 ineffec-tive (14. 58 % ). The total effective rate was 85.42%.

Clinical effect of acupuncture combined with Chinese medicine on optic atrophy caused by neuromyelitis optica

Objective:To explore the clinical effect of acupuncture combined with traditional Chinese medicine on optic nerve atrophy caused by neuromyelitis optic(NMO).Methods:the patients with optic atrophy caused by NMO with optic neuritis who visited the ophthalmology or neuro-ophthalmology clinic of our hospital from March 2016 to December 2019 were collected.The patients were treated with acupuncture and traditional Chinese medicine for 8 weeks before and after treatment.The best corrected visual acuity and dynamic visual field were tested before treatment,4 weeks and 8 weeks after treatment,respectively,to evaluate the effect of acupuncture combined with traditional Chinese medicine on the visual function of patients;Results:after 4 weeks of treatment,the visual acuity of 8 eyes improved more than 2 lines,the total effective rate was 91.67%.after 8 weeks of treatment,the visual acuity of 12 eyes improved more than 2 lines,the total effective rate was 100%;after 4 weeks of treatment,the mean defect(MD)and mean sensitivity(MS)of dynamic visual field were improved,but the difference was not statistically significant(MD:t=1.579,P=0.121;MS:t=-1.500,P=0.140);after 8 weeks of treatment,the MD was significantly decreased(t=2.65,P<0.05),and the MS was significantly improved and statistically significant(t=-2.58,P<0.05).Conclusion:the combination of acupuncture and Chinese medicine can significantly improve the visual function of patients with optic atrophy caused by NMO,improve the best corrected visual acuity and dynamic visual field sensitivity,and reduce the visual field defect.

Acupuncture Therapy for the Treatment of Optic Nerve Atrophy

Objective: Optical Nerve Atrophy is one of the most common causes of blindness worldwide. The condition is linked to several pathologies, which contribute to the damage of the optic nerve. The presence of a tumor on the optic nerve, improper formation of the optic nerve, glaucoma, hereditary and central nervous system diseases, and anterior ischemic optic neuropathy promote deterioration of the optic nerve. The purpose of this review is to examine the efficacy of acupuncture therapy for ONA. Method: Clinical trials (case control-trials), and randomized control trials (RCTs) were assessed to observe the efficacy of acupuncture as well as the safety of acupuncture, needling manipulation, and acupoints selection. The data collected in this research include scientific research papers from China National Knowledge Infrastructure (CNKI), PUBMED library, National Library of Medicine (NLM), EMBASE, Cochrane Library, Chinese Biomedical Literature Database, and other literature library date present. Ophthalmoscope, OCT, pupils test, ocular alignment, nystagmus, and visual acuity check were the diagnostic tools used for ONA in the included study. ONA treatment has been a challenge to ophthalmologists over the past decades. At present, western approaches have no fixed treatment mechanism for the condition. Early diagnosis, the use of magnifying lenses, and reduction of increased fluid around the spinal cord and brain are the multiple disciplinary approaches used in western medicine for ONA. On the other hand, Acupuncture, a branch of traditional Chinese medicine, which stimulates the body’s natural healing ability to promote physical and emotional well-being, has reported some significant treatment effects for ONA. Result: The overall result shows that Acupuncture greatly improved patients’ visual acuity, visual field, and visual function in the included study. Acupuncture acting alone showed significant superiority over other treatments for optical nerve atrophy. Acupuncture combined with medication could improve a patient’s condition more rapidly than medications alone. Conclusion: Optic nerve atrophy is a threatening condition to the vision, which is a leading cause of blindness worldwide. Acupuncture has improved the condition of patients with ONA more effectively than other treatment mechanisms in the included study. However, more clinical trials need to be carried out to substantiate stronger evidence of acupuncture for ONA.

Quantitative analysis of optic disc changes in school-age children with ametropia based on artificial intelligence

AIM:To explore changes in the optic disc and peripapillary atrophy(PPA)in school-age children with ametropia using color fundus photography combined with artificial intelligence(AI)technology.METHODS:Based on the retrospective case-controlled study,226 eyes of 113 children aged aged 6–12y were enrolled from October 2021 to May 2022.According to the results of spherical equivalent(SE),the children were divided into four groups:low myopia group(66 eyes),moderate myopia group(60 eyes),high myopia group(50 eyes)and emmetropia control group(50 eyes).All subjects underwent un-aided visual acuity,dilated pupil optometry,best-corrected visual acuity(BCVA),intraocular pressure,ocular axis measurement and color fundus photography.RESULTS:The width of PPA,horizontal diameter ratio of PPA to the optic disc and area ratio of PPA to the optic disc were significantly different among the four groups(P<0.05).The width of the nasal and temporal neuroretinal rim,the roundness of the optic disc,the height of PPA,the vertical diameter ratio of PPA to the optic disc,and the average density of PPA in the high myopia group were significantly different compared with the other three groups(P<0.05).There were strong negative correlations between SE and area ratio of PPA to the optic disc(r=-0.812,P<0.001)and strong positive correlation between axial length(AL)and area ratio of PPA to the optic disc(r=0.736,P<0.001).CONCLUSION:In school-age children with high myopia,the nasal and temporal neuroretinal rims are narrowed and even lost,which have high sensitivity.The area ratio of the PPA to the optic disc could be used as an early predictor of myopia progression,which is of great significance for the development prevention and management of myopia.

视神经萎缩蛋白1与糖尿病心肌病相关性的研究进展

糖尿病心肌病(DCM)是指单纯由高血糖引起的心肌细胞或心脏微血管损伤及代谢障碍。有研究表明,DCM与线粒体融合异常密切相关。视神经萎缩蛋白1(Opa1)是线粒体融合的主要蛋白之一。在高血糖环境下,Opa1表达减少,造成线粒体融合障碍,进而引起心肌细胞能量代谢障碍、氧化应激、胰岛素抵抗与脂毒性增加、细胞凋亡等,最终导致DCM。上调Opa1的表达则能使DCM的症状得到改善。该文就Opa1与DCM的相关性的研究进展做一综述,为DCM的研究提供新思路。

Characterization,expression dynamics,and potential function of OPA1 for regulation of mitochondrial morphology during spermiogenesis in Phascolosoma esculenta

Mitochondria undergo morphological changes during spermatogenesis in some animals.The mechanism and role of mitochondrial morphology regulation,however,remain somewhat unclear.In this study,we analyzed the molecular characteristics,expression dynamics and subcellular localization of optic atrophy protein 1(OPA1),a mitochondrial fusion and cristae maintenance-related protein,to reveal the possible regulatory mechanisms underlying mitochondrial morphology in Phascolosoma esculenta spermiogenesis.The full-length cDNA of the P.esculenta opa1 gene(Pe-opa1)is 3743 bp in length and encodes 975 amino acids.The Pe-OPA1 protein is highly conservative and includes a transmembrane domain,a GTPase domain,two helical bundle domains,and a lipid-interacting stalk.Gene and protein expression was higher in the coelomic fluid(a site of spermatid development)of male P.esculenta and increased first and then decreased from March to December.Moreover,their expression during the breeding stage was significantly higher than during the non-breeding stage,suggesting that Pe-OPA1 is involved in P.esculenta reproduction.The Pe-OPA1 protein was more abundant in components consisting of many spermatids than in components without,indicating that Pe-OPA1 mainly plays a role in the spermatid in coelomic fluid.Moreover,Pe-OPA1 was mainly detected in the spermatid mitochondria.Immunofluorescence experiments showed that the Pe-OPA1 are constitutively expressed and co-localized with mitochondria during spermiogenesis,suggesting its involvement in P.esculenta spermiogenesis.These results provide evidence for Pe-OPA1's involvement in the regulation of mitochondrial morphology during spermiogenesis.

基于伏邪理论从“寒热-痰瘀-虚劳”角度分期辨治肺痿

肺痿是以肺叶痿弱为特征的慢性肺脏虚损性疾病,以咳唾涎沫、气短为主症,与现代医学特发性肺纤维化(IPF)相类似。临床以咳嗽、进行性呼吸困难、喘促胸闷为主要表现,甚则呼吸衰竭危及生命。肺痿属于古代疑难杂症,现代医学治疗亦十分棘手。汉代张机从“寒热-痰瘀-虚劳”的角度阐述了肺痿的主要病机,开创了治疗肺痿之先河。肺痿的病因病机复杂多样,病情迁延难愈,与伏邪理论“伏而不发”的特点不谋而合。因此,基于伏邪理论,结合中西医病机特点,进一步探讨肺痿早期、进展期、终末期3个阶段的分期论治思路,以期为肺痿不同阶段论治提供新的辨证论治思路。
