Objective To observe the curative effect of comprehensive traditional Chinese medicine(TCM)therapy for the treatment of refractory sudden hearing loss(i.e.,suffering sudden hearing loss more than 2 weeks),and to analyze the factors that may affect the prognosis.Methods A retrospective analysis was carried out in 405 hospitalized patients with refractory sudden hearing loss who were treated in the Department of Otorhinolaryngology,the First Affiliated Hospital of Guangzhou University of Chinese Medicine from 2005 to 2022.The patients were all treated by comprehensive TCM therapy including oral administration of Chinese medicine,acupuncture,acupoint seed-pressing application after individualized syndrome differentiation.The overall clinical efficacy was evaluated,and the difference of efficacy in the patients with various courses of disease,degrees of deafness,types of hearing curve,concomitant symptoms and TCM syndrome types,having or not having previous treatment history was analyzed.Results For the 405 patients with refractory sudden hearing loss,the cure rate was 5.7％and the total effective rate was 28.1％.Among the 405 patients,the best efficacy was achieved in the patients with mild hearing loss,low-frequency decline type of hearing curve,and having no previous treatment history,and the differences were statistically significant(P＜0.05 or P＜0.01).There was no significant difference in the efficacy of patients with different courses of disease,with or without concomitant symptoms,or with various syndrome types(P＞0.05).Conclusion The comprehensive TCM therapy has a certain effect on refractory sudden hearing loss.Patients with poor efficacy after conventional western medicine can still benefit from the comprehensive TCM therapy.

OBJECTIVE: To observe the clinical effect and safety of acupuncture in treatment of neck pain due to cervical spondylosis. METHODS: According to the patients' preference and acceptance for the interventions of neck pain induced by cervical spondylosis, an acupuncture group (221 cases) and a non-acupuncture group (251 cases) were divided. After the control of confounding factors with propensity score matching, 218 cases were included in either acupuncture group or non-acupuncture group. In the acupuncture group, acupuncture was applied to Dazhui (GV 14), Baihui (GV 20), ashi points, bilateral neck-Jiaji (EX-B 2), Fengchi (GB 20), Houxi (SI 3), Shenmai (BL 62), etc. The treatment was given once daily, one course of intervention was composed of 5 treatments and 3 courses were included. In the non-acupuncture group, the oral administration of imrecoxib tablets and cobalt tablets was prescribed for 2 weeks. Before and after treatment, the scores of Northwick Park questionnaire (NPQ) and the simplified McGill pain questionnaire (SF-MPQ) were observed, and the safety was assessed in patients of the two groups. RESULTS: After treatment completion, the scores of NPQ and SF-MPQ were all reduced when compared with those before treatment in each group (P<0.001), and the scores of NPQ and SF-MPQ in the acupuncture group were lower than those of the non-acupuncture group (P<0.001). The incidence of adverse reactions was 6.0% (13/218) in the acupuncture group and was 10.1% (22/218) in the non-acupuncture group, without statistical significance in comparison (P>0.05). CONCLUSION Acupuncture is effective and safe in the relief of neck pain and the improvement of comprehensive quality of life in the patients with cervical spondylosis.

Objective: To analyze the genetic landscape of 52 fusion genes in patients with de novo acute lymphoblastic leukemia (ALL) and to investigate the characteristics of other laboratory results. Methods: The fusion gene expression was retrospectively analyzed in the 1 994 patients with de novo ALL diagnosed from September 2016 to December 2020. In addition, their mutational, immunophenotypical and karyotypical profiles were investigated. Results: In the 1 994 patients with ALL, the median age was 12 years (from 15 days to 89 years). In the panel of targeted genes, 15 different types of fusion genes were detected in 884 patients (44.33%) and demonstrated a Power law distribution. The frequency of detectable fusion genes in B-cell ALL was significantly higher than that in T-cell ALL (48.48% vs 18.71%), and fusion genes were almost exclusively expressed in B-cell ALL or T-cell ALL. The number of fusion genes showed peaks at<1 year, 3-5 years and 35-44 years, respectively. More fusion genes were identified in children than in adults. MLL-FG was most frequently seen in infants and TEL-AML1 was most commonly seen in children, while BCR-ABL1 was dominant in adults. The majority of fusion gene mutations involved signaling pathway and the most frequent mutations were observed in NRAS and KRAS genes. The expression of early-stage B-cell antigens varied in B-cell ALL patients. The complex karyotypes were more common in BCR-ABL1 positive patients than others. Conclusion: The distribution of fusion genes in ALL patients differs by ages and cell lineages. It also corresponds to various gene mutations, immunophenotypes, and karyotypes.

OBJECTIVE: To investigate the short-term clinical effect of lumbar nerve root canal injection under X-ray angiography in the treatment of sciatica. METHODS: The clincal data of 78 patients with sciatica underwent lumbar nerve root canal injection under X-ray angiography from December 2017 to February 2020 was retrospectively analyzed. Including 31 males and 47 females, aged from 22 to 88 years old with a median of 65 years. There were 55 cases of lumbar disc herniation and 23 cases of lumbar spinal stenosis, the course of disease ranged from 1 to 8 weeks with a median of 3 weeks. There were 71 cases of single segment disc herniation or stenosis, including L_3,4 of 5 cases, L_4,5 of 61 cases, L₅S₁ of 5 cases, and 7 cases of multisegment herniation or stenosis. The pain visual analogue scale (VAS) was recorded and Macnab was used to evaluate the clinical effect. RESULTS: All patients completed standardized treatment without serious adverse reactions. VAS were (3.21±0.76) scores immediately after treatment, (2.89±0.33) scores 1 hour after treatment, (1.80±0.27) scores 6 hours after treatment, (1.10±0.20) scores 24 hours after treatment, (2.53±0.35) scores 1 week after treatment and (4.27±0.36) scores 1 month after treatment. There were significant differences in VAS between before treatment(7.83±0.56) and each time period after treatment(P<0.05). According to Macnab low back pain evaluation standard, 42 cases were effective, 34 cases were markedly effective and 2 cases were ineffective within 24 hours after treatment, with an effective rate of 97.4%;38 cases were effective, 25 cases were markedly effective, 15 cases were ineffective within one week after treatment, the effective rate was 80.0%;32 cases were effective, 22 cases were markedly effective, 24 cases were ineffective within one month after treatment, the effective rate was 69.2%. CONCLUSION The short-term clinical effect of nerve root canal injection under X-ray radiography in the treatment of sciatica is good and it is an effective method to relieve sciatica.

Objective: To determine the characteristics and progress of the visual acuity and refractive state of schoolchildren in Huangzhong District, Xining City, Qinghai Province in China. Methods: Cohort study. Department of Ophthalmology, Beijing Children's Hospital carried out a cohort study by collecting the visual acuity and refractive state of Grade 1-5 schoolchildren among 16 primary schools in Huangzhong District, Xining City, Qinghai Province in September 2020 and July 2021. Cycloplegic retinoscopy with eye drop which contained tropicamide (0.5%) and phenylephrine hydrochloride (0.5%) was performed in children with low vision(<1.0). Myopia was defined as the spherical equivalent (SE) ≤-0.5 D after cycloplegic retinoscopy. Measurement data was analyzed by t-test and enumeration data was analyzed by χ² test. Multiple linear regression was used to analyze the influencing factors. Results: The 2 489 individuals with repeated tests in two years were included in the follow-up study, among whom the prevalence of myopia was 26.24%(653/2 489) in 2020, while 32.94% (820/2 489)respectively in 2021. The incidence of myopia in one school year from grades 1 to 5 was 11.19%(47/420), 5.44%(21/386), 6.39%(25/391), 11.52%(44/382) and 11.67%(30/257). The average SE of children in all grades in 2021 increased negatively from the previous year (Grade 1 to Grade 5 increased respectively: 0.40 D, 0.69 D, 0.62 D, 0.52 D and 0.37 D). Conclusions: The prevalence of myopia among schoolchildren in Huangzhong District, Xining City, Qinghai Province was relatively high. There were two peaks of myopia incidence in the first, fourth and fifth grades. Female, age, and the baseline of SE were the related influencing factors for myopia progression.

Objective: To investigate the mutational features of the immunoglobulin heavy chain variable region (IgHV) gene in patients with chronic lymphocytic leukemia (CLL) using immunophenotypic and molecular genetic methods. Methods: The laboratory results of 266 CLL patients who underwent IgHV gene examination at Sino-US diagnostics laboratory from February 2020 to February 2021 were analyzed for the IgVH mutational status and presence of specific IgVH fragments. In addition, their immunophenotypic, molecular, chromosomal karyotypic, and FISH profiles were investigated and correlated with the IgVH mutational status. Results: Among 266 patients, 172 were male and 94 were female, with a media age of 67 years (20-82 years).There were more patients with mutated IgHV (m-IgHV) than unmutated IgHV (un-IgHV) (69.2%∶30.8%). There was association of VH family and the presence of gene fragments: the overall incidence of VH families including VH3 family (142/266, 53.4%), VH4 family (75/266, 28.2%), and VH1 family (34/266, 12.8%) was about 95%, among which the proportion of VH4-34 (26/266, 9.8%), VH3-23 (25/266, 9.4%), VH3-7 (24/266, 9.0%), and VH4-39 (16/266, 6.0%) was about 35%. VH3-20 and VH3-49 only occurred in un-IgHV (P<0.05). In addition, the expression rates of CD38 (26.3% vs. 3.0%), CD79b (71.1%∶45.5%) and 11q deletion (25.5%∶5.3%) were higher in un-IgHV, and single trisomy 12 (37.9%∶5.6%) were more commonly found in m-IgHV (P<0.05). MYD88 was one of the major mutation genes in m-IgHV, while ATM had the highest mutation rate in un-IgHV. Conclusion: CLL patients have differential expression in terms of IgHV gene mutations, correlating to their immunophenotype and genetics characteristics.

ObjectiveTo study the changes of miRNAs in exosomes secreted from microglia after being activated by exosomes of SH-SY5Y cells overexpressing α-synuclein （SNCA-HM Exo） and their effects on autophagy of SH-SY5Y cells． MethodsMicroglia exosomes were collected for miRNAs microarray analysis and PCR detection， and the differentially expressed miRNAs were screened out. Their target genes were analyzed by Kyoto Encyclopedia of Genes and Genomes （KEGG） and Gene Ontology （GO）. MiRNAs and their target genes related to PI3K/Akt/signaling pathway were screened out and verified by Western blot. The SH-SY5Y cells were divided into four groups：Con-HM Exo，Con-HM Exo+miR-19a mimic，SNCA-HM Exo and SNCA-HM Exo+miR-19a-3p inhibitor. ResultsFifteen differentially expressed miRNAs were screened out by microarray analysis and PCR. KEGG and GO analysis showed that PI3K/Akt signaling pathway had the highest enrichment score of target genes， and PTEN was one of the target genes regulated by mir-19a-3p. We found that， compared with the control group， the expression of PTEN and LC3 Ⅱ/I were decreased， while the expression of p-Akt/Akt， p-mTOR/mTOR and p62 were increased in the miR-19a-3p mimic group and the SNCA-HM Exo group （P < 0.05）. However， miR-19a-3p inhibitor could reverse this effect （P < 0.05）. ConclusionSNCA-HM Exo regulates PTEN through miR-19a-3p， activates PI3K/Akt/mTOR signaling pathway， and then inhibits autophagy in SH-SY5Y cells．

OBJECTIVE: To establish a new mechanical model of distal humerus in children with epiphysial cartilage, stimulate supracondylar humerus fracture and perform three dimensional finite elements, and study effect of pins numbers, pin tract, outlet height and pin configurations on stability of fixation. METHODS: Three dimensional computed tomography (CT) data of 6-year-old boy with distal humerus was downloaded from picture archiving and communications systems software (PACS), the data of picture was imported into Simpleware and SolidWorks 2016 software to establish distal humerus fracture in children contained ossific nucleus of the capitellum (ONC) and distal cartilage. Normal extense supracondylar humerus fracture model was established to stimulate configurations of crossed and lateral pinning fixation, 30 N was added on the direction of flexion extension and varus valgus, while 50 N was added on the direction of internal and external turning. Stability was analyzed by displacement degree of distal fracture. RESULTS: Among 2-pin configurations, 2-crossed pins were more stable against rotation forces which could resist rotation stress over 2 585 Nmm/ °, while low position through ONC of 2-divergent lateral pins were more stable, which could resist stress of 45 N /mm and 190 N /mm during the test of resistant strains and varus-valgus stress. The third pins was added into the more stable lateral 2-pins, the stability in all directions were increased obviously, and 3 crossed pins is the most stable, stress of flexion-extension, varus-valgus and internal-external turning were 198 N /mm, 395 N /mm and 6 251 Nmm/ °. CONCLUSION Two-divergent lateral pins could provide enough stability for supracondylar humerus fracture in children. In two-crossed pins, the upper border of MDJ could provide the best stability. Three-crossed pins could offer the best stability against both translation and rotation forces.
