Objective:To analyze genetic factors and phenotype characteristics in pediatric population with slight-to-moderate sensorineural hearing loss. Methods:Children with slight-to-moderate sensorineural hearing loss of and their parents, enrolled from the Chinese Deafness Genome Project, were studied. Hearing levels were assessed using pure tone audiometry, behavioral audiometry, auditory steady state response（ASSR）, auditory brainstem response（ABR） thresholds, and deformed partial otoacoustic emission（DPOAE）. Classification of hearing loss is according to the 2022 American College of Medical Genetics and Genomics（ACMG） Clinical Practice Guidelines for Hearing Loss. Whole exome sequencing（WES） and deafness gene Panel testing were performed on peripheral venous blood from probands and validations were performed on their parents by Sanger sequencing. Results:All 134 patients had childhood onset, exhibiting bilateral symmetrical slight-to-moderate sensorineural hearing loss, as indicated by audiological examinations. Of the 134 patients, 29（21.6%） had a family history of hearing loss, and the rest were sporadic patients. Genetic causative genes were identified in 66（49.3%） patients. A total of 11 causative genes were detected, of which GJB2 was causative in 34 cases（51.5%）, STRC in 10 cases（15.1%）, MPZL2 gene in six cases（9.1%）, and USH2A in five cases（7.6%）.The most common gene detected in slight-to-moderate hearing loss was GJB2, with c. 109G>A homozygous mutation found in 16 cases（47.1%） and c. 109G>A compound heterozygous mutation in 9 cases（26.5%）. Conclusion:This study provides a crucial genetic theory reference for early screening and detection of mild to moderate hearing loss in children, highlighting the predominance of recessive inheritance and the significance of gene like GJB2, STRC, MPZL2, USH2A.

OBJECTIVES: To observe the clinical efficacy of moxibustion as an adjunctive treatment for rheumatoid arthritis (RA) based on conventional medication and its effects on serum sclerostin (SOST) and β-catenin levels, exploring the potential mechanisms by which moxibustion may protect joint bones in RA patients. METHODS: Seventy-six RA patients were randomly divided into an observation group (38 cases, 3 cases dropped out) and a control group (38 cases, 4 cases were eliminated, 2 cases dropped out). The patients in the control group were treated with conventional oral medication; based on the treatment of the control group, the patients in the observation group were treated with moxibustion. The direct moxibustion was applied at Zusanli (ST 36) on both sides and ashi points around small joints, and indirect moxibustion was applied at Shenshu (BL 23) on both sides and ashi points around large joints. The treatment was given three times a week for a total of 5 weeks. The count of pain and swollen joint, morning stiffness score, disease activity score of 28 joints (DAS28), visual analogue scale (VAS) score, health assessment questionnaire (HAQ) score, and serum levels of SOST, β-catenin, and tumor necrosis factor-α (TNF-α) were evaluated before and after treatment in the two groups. RESULTS: Compared those before treatment, after treatment, both groups showed a reduction in pain and swollen joint count (P<0.01, P<0.05), morning stiffness, DAS28, VAS, and HAQ scores (P<0.01, P<0.05), with the observation group having lower scores than the control group (P<0.01). Serum levels of SOST, β-catenin, and TNF-α after treatment in the observation group were lower than those in both before treatment and the control group (P<0.01, P<0.05). There was a positive correlation between the difference in serum β-catenin levels before and after treatment and the difference in serum SOST (r=0.578, P<0.001) and TNF-α (r=0.403, P<0.05) levels in the observation group. CONCLUSIONS In addition to medication, moxibustion as an adjunctive treatment could significantly alleviate joint pain and reduce disease activity in RA patients, suggesting a potential role in joint protection. This mechanism may be related to the inhibition of the inflammatory factor TNF-α, regulation of β-catenin levels, and reduction in the production of the endogenous negative regulator protein SOST within the Wnt/β-catenin signaling pathway.

OBJECTIVE: To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies. METHODS: A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI. RESULTS: All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up. CONCLUSION For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

OBJECTIVE: To investigate the relationship between bone marrow edema and pathological changes, symptoms and signs of severe knee osteoarthritis. METHODS: From January 2020 to March 2021, 160 patients with severe knee osteoarthritis who underwrent MRI of the knee at the Department of Bone and Joint, Wangjing Hospital, China Academy of Chinese Medical Sciences were included. Eighty patients with bone marrow edema were selected as the case group, including 12 males and 68 females, aged from 51 to 80 years old with an average of (66.58±8.10) years old, the duration of disease 5 to 40 months with an average of (15.61±9.25) months. Eighty patients without bone marrow edema were selected as the control group, including 15 males and 65 females, aged from 50 to 80 years old with an average of (67.82±8.05) years old, the duration of disease 6 to 37 months with an average of (15.75±8.18) months, BMI was (28.26±3.13) kg·m^-2 ranged from 21.39 to 34.46 kg·m^-2. The degree of bone marrow edema was evaluated by knee whole oragan magnetic resonance imaging score (WORMS). The degree of knee osteoarthritis was evaluated by Kellgren- Lawrence(K-L) grade and Western Ontario and McMaster University Osteoarthritis Index (WOMAC). The degree of joint pain was evaluated by visual analogue scale(VAS) and WOMAC pain score, the joint signs were evaluated by tenderness, percussion pain, joint swelling and joint range of motion. To explore the relationship between bone marrow edema and knee osteoarthritis, the prevalence of bone marrow edema and K-L grade were compared between the two groups. Furthermore the WORMS score and WOMAC index, pain-related score, and sign-related score correlation coefficient were analyzed to further explore the relationship between bone marrow edema and knee osteoarthritis index, joint pain symptoms and signs. RESULTS: There was 68.75% (55/80) of the patients in the case group were in K-L grade Ⅳ, and 52.5% (42/80) in the control group, indicating a higher proportion of patients with grade Ⅳ in the case group than the control group (χ²=4.425, P<0.05). In the case group, there was a strong correlation between bone marrow edema WORMS score and knee osteoarthritis WOMAC index. (r=0.873>0.8, P<0.001), a moderate correlation between WORMS score and VAS score and WOMAC pain score(r=0.752, 0.650>0.5, P<0.001), a moderate correlation between WORMS score and percussion pain score (r=0.784>0.5, P<0.001), and a weak correlation between WORMS score and VAS and tenderness score, joint swelling score and joint range of motion score (r=0.194, 0.259, 0.296<0.3, P<0.001). CONCLUSION Our study suggests that severe knee osteoarthritis is associated with an increased risk of bone marrow edema. Bone marrow edema can also lead to knee osteoarthritis joint pain, with percussion pain being a positive sign, but tenderness, joint swelling and limitation of activity are not significantly related to bone marrow edema.

OBJECTIVE: To observe the immediate analgesic effect of electroacupuncture (EA) combined with diclofenac sodium on acute gouty arthritis (AGA). METHODS: A total of 90 patients with AGA were randomly divided into a low-dose medication (LM) group (30 cases, 1 case was eliminated, 1 case dropped off), a conventional medication (CM) group (30 cases, 1 case dropped off) and a combination of acupuncture and medication (AM) group (30 cases ). The LM group was given oral administration of 50 mg diclofenac sodium sustained-release capsule; the CM group was given oral administration of 100 mg diclofenac sodium sustained-release capsule; on the basis of the treatment of LM group, the AM group was treated with electroacupuncture at ashi points, Dadu (SP 2), Taichong (LR 3), Taibai (SP 3), Neiting (ST 44), Sanyinjiao (SP 6), Zusanli (ST 36) and Yinlingquan (SP 9) on the affected side, and Taichong (LR 3) and Zusanli (ST 36), Sanyinjiao (SP 6) and Yinlingquan (SP 9) were connected to electroacupuncture respectively, continuous wave, 2 Hz in frequency. The visual analogue scale (VAS) scores of pain before treatment and after 10 min, 2 h, 4 h and 6 h of treatment completion, joint tenderness and swelling scores before treatment and after 10 min and 6 h of treatment completion were compared, and the rate of diclofenac sodium addition within 24 h after treatment completion was recorded among the three groups. RESULTS: After 10 min of treatment completion, the scores of VAS, joint tenderness and joint swelling in the AM group were lower than those before treatment (P<0.05), and the VAS score in the AM group was lower than that in the other two groups (P<0.05). After 2, 4 and 6 h of treatment completion, the VAS scores of the three groups were lower than those before treatment (P<0.05), and the scores in the AM group were lower than those in the LM group (P<0.05). After 6 h of treatment completion, the joint tenderness scores of the three groups and the joint swelling scores of the AM group and the CM group were lower than those before treatment (P<0.05), and the joint tenderness and swelling scores of the AM group were lower than those of the LM group (P<0.05). The rate of diclofenac sodium addition was 3.3 % (1/30) and 3.4 % (1/29) in the AM group and the CM group, respectively, which were lower than 17.9% (5/28) in the LM group (P<0.05). CONCLUSION Electroacupuncture combined with diclofenac sodium have a good immediate analgesic effect in the treatment of AGA, and have the advantages of small dosage of analgesic drugs and less adverse reactions.

OBJECTIVE: To analyze the clinical features and genetic variant in a patient with Usher syndrome. METHODS: Whole exome sequencing was carried out for the patient. Suspected variants were validated by Sanger sequencing of her parents and fetus. RESULTS: The proband was found to harbor compound heterozygous variants c.17_18insA (p.Tyr6Ter*) and c.4095_4096insA (p.Arg1366Lys fs*38) of the PCDH15 gene (NM_033056), which were respectively inherited from her father and mother. The same variants were not detected in 100 healthy controls. Based on the guidelines of the American Society of Medical Genetics and Genomics, both variants were predicted to be pathogenic (PVS1+PM2+PP4). By prenatal diagnosis, her fetus was found to carry the c.4095_4096insA variant. After birth, the child has passed neonatal hearing screening test, and no abnormal auditory and visual function was found after the first year. CONCLUSION The compound heterozygous variants c.17_18insA (p.Tyr6Ter*) and c.4095_4096insA (p.Arg1366Lys fs*38) of the PCDH15 gene probably underlay the Usher syndrome is this proband.

Brain-lung-thyroid syndrome is a rare autosomal dominant disorder. More than 100 cases have been reported worldwide, but few cases have been reported in China. In December 2018, a boy with brain-lung-thyroid syndrome, aged 3 years and 10 months, was admitted to Xiangya Hospital of Central South University due to repeated cough for more than 3 years. In infancy of the boy, psychomotor retardation, repeated cough, and hypothyroidism were found. Gene detection showed that there was c.927delc heterozygous variation in NKX2-1 gene (NM-001079668: exon3: c.927delC). The variation of this gene locus has not been reported in relevant literature so far, which indicates a new mutation. According to the above clinical manifestations and examination results, the boy was diagnosed as brain-lung-thyroid syndrome, which mainly characterized by nervous system disorders, accompanied by respiratory manifestations and hypothyroidism. The boy was treated with oral dopasehydrazine to relieve tremor and levothyroxine sodium tablets to relieve hypothyroidism. Anti-infection, atomization, rehabilitation training and other symptomatic supporting treatment were also administered. The boy's language and movement have improved, the thyroid hormone level is normal, and there are still repeated respiratory tract infections.

OBJECTIVES: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation and joint destruction. Both inflammatory response and oxidative stress contribute to the pathogenesis of RA. Oxidative damage can induce and aggravate the imbalance of immune inflammation and promote cell and tissue damage. In this study, the expression of long non-coding RNA (lncRNA) LINC00638 in peripheral blood of patients with RA damp-heat arthralgia syndrome was observed, and the correlation between LINC00638 and disease activity, immune inflammation and oxidative stress indicator was investigated. Subsequently, the mechanisms for LINC00638 in regulating the inflammatory response and oxidative stress in RA fibroblast-like synoviocyte (FLS) under the condition of overexpression and interference were further explored. METHODS: In this study, 48 RA patients with damp-heat arthralgia syndrome and 27 normal healthy subjects, who came from Department of Rheumatology, First Affiliated Hospital of Anhui University of Chinese Medicine, were included; and they were divided into a RA group and a control group. The expression of LINC00638 in peripheral blood mononuclear cells (PBMC) from the subjects was detected by real-time PCR. Enzyme linked immunosorbent assay (ELISA) was used to detect serum interleukin (IL)-10, IL-17, tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), heme oxygenase 1 (HO-1) and superoxide dismutase 2 (SOD2) expression. Spearman method was used to study the relationship between LINC00638 and erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (anti-CCP), and to observe the relation between LINC00638 and the Disease Activity Score of 28 Joint (DAS28), Quantitative Score of Damp Heat Syndrome, Visual Analogue Scale (VAS), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS). RA-FLS was induced by RA-PBMC, and the RA in vitro cell experimental model was established. LINC00638 overexpression plasmid and small interfering RNA (siRNA) were constructed and transfected into RA-FLS. The cell experiments were divided into 4 groups: a pcDNA3. 1- control group, a pcDNA3.1-LINC00638 group, a siRNA-control group, and a siRNA-LINC00638 group. The transfection efficiency of overexpression plasmid and siRNA was detected by real-time PCR, the expression of TNF-α and IL-10 was detected by ELISA, and the expression of antioxidant proteins HO-1 and SOD2 was detected by immunofluorescence. RESULTS: Compared with the control group, the expression of LINC00638 in the RA group was lower (P<0.01). The area under the curve (AUC) of the receiver operating characteristic (ROC) curve of LINC00638 was 0.9271. The DAS28 in RA group was 5.70 (5.40-6.50), the Quantitative Score of Damp-heat Syndrome was 20.0 (17.0-23.0), and the VAS score was 7.0 (6.3-8.0). Compared with the control group, the ESR, CRP, RF, anti-CCP, SAS and SDS scores in the RA group were significantly increased (all P<0.01). Spearman correlation analysis showed that: LINC00638 was negatively correlated with ESR (r=-0.532, P<0.01), CRP (r=-0.367, P<0.05), TNF-α (r=-0.375, P<0.01), MDA (r= -0.295, P<0.05), DAS28 (r=-0.450, P<0.01), and which was positively correlated with SOD2 (r=0.370, P<0.05). After the induction of RA-FLS, the expression level of LINC00638 was significantly decreased (P<0.01), indicating that the stimulation of PBMC could effectively reduce the expression of LINC00638 in RA-FLS, so the experimental model of RA-FLS-induced by PBMC was utilized. Compared with the pcDNA3.1-control group, the expressions of LINC00638, IL-10, SOD2, and HO-1 in the pcDNA3.1-LINC00638 group were significantly increased (all P<0.01), and the expression of TNF-α was decreased (P<0.01). Compared with siRNA-control group, LINC00638, IL-10, SOD2 and HO-1 in the siRNA-LINC00638 group were significantly decreased (all P<0.01), and TNF-α was significantly increased (P<0.01). CONCLUSIONS LINC00638 is down-regulated in the peripheral blood of RA patients with damp-heat arthralgia syndrome, which is correlated with disease activity, immune inflammation and oxidative stress. Overexpression of LINC00638 can down-regulate pro-inflammatory factors, up-regulate anti-inflammatory factors, and increase antioxidant enzyme activity, thereby improving inflammation and oxidative stress in RA. LINC00638 is the differential lncRNA obtained by the research group's previous high-throughput sequencing of the whole transcriptome of peripheral blood PBMCs in RA patients and validation of clinical samples. In order to deepen the molecular biology research of this gene, the microRNA and mRNA targeted by LINC00638 can be further studied from the perspective of competing endogenous RNAs.

Objective: To investigate the clinical features of children with chronic nonbacterial osteomyelitis (CNO), and raise awareness among clinicians. Methods: In this retrospective study, 18 patients with CNO who were diagnosed in Children's Hospital of Fudan University from January 2015 to December 2021 were included. Results: Eighteen children with CNO (12 males, 6 females) were identified. Their age at onset was 9 (5, 11) years, the delay in diagnosis was 2 (1, 6) months, and follow-up-was 17 (8, 34) months. The most common symptoms were fever in 14 children, as well as bone pain and (or) arthralgia in 14 children. In terms of laboratory results, normal white blood cell counts were observed at onset in 17 patients; increased erythrocyte sedimentation rate (ESR) in all patients; increased C reactive protein (CRP) over the normal value in 14 patients. Of the 18 patients, 2 had positive antinuclear antibodies, while none had positive human leukocyte antigen-B27 or rheumatoid factor. Imaging examination revealed that all the patients had symmetrical and multifocal skeletal lesions. The number of structural lesions detected by imaging investigation was 8 (6, 11). The most frequently affected bones were tibia in 18 patients and femur in 17 patients. Bone biopsy was conducted in 14 patients and acute or chronic osteomyelitis manifested with inflammatory cells infiltration were detected. Magnetic resonance imaging (MRI) found bone lesions in all the patients and bone scintigraphy were positive in 13 patients. All the patients were treated with nonsteroidal anti-inflammatory drugs, among whom 10 cases also treated with oral glucocorticoids, 9 cases with traditional disease modifying anti-rheumatic drugs, 8 cases with bisphosphonates and 6 cases with tumor necrosis factor inhibitors. The pediatric chronic nonbacterial osteomyelitis disease activity score, increased by 70% or more in 13 patients within the initial 6-month follow-up. Conclusions: The clinical manifestations of CNO are lack of specificity. The first symptom of CNO is fever, with or without bone pain and (or) arthralgia, with normal peripheral blood leukocytes, elevated CRP and (or) ESR. Whole body bone scanning combined with MRI can early detect osteomyelitis at subclinical sites, and improve the diagnostic rate of CNO.

Objective: MRI images were used to study the efficacy of anterior repositioning splint (ARS) in the treatment of different types of disc displacement with reduction (DDWR) in temporomandibular joint. Methods: From September 2020 to December 2021, 26 patients with DDWR were enrolled in the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Zhengzhou University. There were 5 males and 21 females with an average age of (20.8±5.8) years. ARS was used for 3-6 months. The changes of joint clicking, opening type and joint pain before and after treatment were compared. The changes of disc position, disc-condyle angle and condylar bone mass before and after treatment were compared by MRI. Paired t-test was performed on the disc-condyle angle before and after treatment, Fisher's exact test was performed on the change of disk position, and other count data were expressed as rate (%). Results: After ARS treatment, the effective rates of joint clicking,abnormal opening, joint pain and disc displacement were 97%(35/36), 14/18, 7/9 and 95%(36/38). MRI analysis found that there was a significant difference between the disc position before and after treatment (P<0.001), MRI analysis showed that the anterior disc displacement (48%, 25/52) and the anterolateral disc displacement (17%, 9/52) were the most common before treatment. In contrast, the normal superior disc (75%, 39/52) and the anterior disc displacement (17%, 9/52) were the most common after treatment, no significant changes were seen after treatment in the anteromedial disc displacement. The disc-condylar angle was (36.09±19.02) ° before ARS treatment and (3.94±10.12) ° after ARS treatment(t=9.23, P<0.001). After treatment, 46% (12/16) of the patients showed new bone formation, and the height of the condyle recovered. Conclusions: The clinical efficacy of ARS in the treatment of anterior disc displacement and anterolateral displacement of temporomandibular joint is remarkable, which can restore the disc-condylar relationship of most patients with indications.
