OBJECTIVE:
To investigate the effectiveness of endoscopic-assisted median nerve decompression with one-stage extensor indicis proprius (EIP) tendon transfer for reconstruction of thumb abduction in patients with severe carpal tunnel syndrome (CTS).
METHODS:
The clinical data of 12 patients with severe CTS who met the selection criteria between December 2019 and December 2024 were retrospectively analyzed. There were 2 males and 10 females with an average age of 55.4 years ranging from 35 to 67 years. The symptom duration of CTS was 12-120 months (mean, 48.7 months) and the thenar muscle atrophy duration was 6-48 months (mean, 13.4 months). The median nerve was released with the help of endoscope, and the EIP tendon was transferred to reconstruct the abduction function of the thumb. The operation time and complications were recorded. Two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, and pinch force of the thumb were measured and compared before operation and at last follow-up, and the effectiveness was evaluated by Kapandji score and Disabilities of the Arm, Shoulder and Hand (DASH) score. The satisfaction of the operation was evaluated at last follow-up.
RESULTS:
All surgeries were successfully completed with a mean operation time of 54 minutes (range, 45-68 minutes). All patients were followed up 6-50 months, with an average of 15.3 months. There was no complications such as wound infection, scar pain of wrist, or tendon rupture of transposition, and there were 3 cases of mild limitation of finger extension in the donor site of index finger. At last follow-up, two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, Kapandji score, and DASH score were significantly better than those before operation ( P<0.05), but there was no significant difference in thumb pinch force between pre- and post-operation ( P>0.05). The evaluation of surgical satisfaction showed that 7 cases were very satisfied and 5 cases were satisfied.
CONCLUSION
The combination of endoscopic-assisted median nerve decompression and one-stage EIP tendon transfer effectively improves hand function and quality of life in patients with severe CTS by restoring thumb abduction and alleviating neurological symptoms.

Objective:To explore the trend of hearing changes in infants with GJB2 gene p.V37I mutation at different months. Methods:The subjects were 54 children(108 ears) with p.V37I homozygous or compound heterozygous mutation in GJB2 gene. All the subjects underwent auditory brainstem response, auditory steady-state response, acoustic immittance and other audiological tests. Children were divided into three groups according to their age, 26 cases in group A were ≤3 months old, 17 cases in group B were>3~≤6 months old, and 11 cases in group C were>6 months old. Statistical analysis was performed on the three groups of ABR response threshold, hearing degree, the ASSR average response threshold of four frequencies and the ASSR response thresholds for each frequency of 500, 1 000, 2 000 and 4 000 Hz. Results:Among the 54 cases, 35 were male and 19 were female, with an age rang of 2-27 months and a median age of 4 months. The ABR response threshold of the three groups were ranked from low to high as group A, group B and group C, and the difference was statistically significant(P<0.05). The ABR response thresholds of the three groups were ranked from low to high as group A, group B, and group C. The comparison between groups showed that the ABR response thresholds of group C was higher than that of group A(P=0.006). The proportion of confirmed hearing loss in the three groups was 34.61%, 50.00% and 63.64%, respectively, and the difference of hearing level among the three groups was statistically significant(P<0.05). The comparison between groups showed that the difference between group A and group C was statistically significant(P=0.012), normal hearing accounted for the highest proportion in group A(65.39%), while mild hearing loss accounted for the highest proportion in group C(45.46%). The ASSR average response thresholds of the four frequencies in the three groups were ranked from low to high as group A, group B and group C, and the difference is statistically significant(P<0.05). The comparison between groups showed that response ASSR thresholds of group C was higher than that of group A(P=0.002). Response thresholds of ASSR in each frequency in the three groups were all ranked from low to high as in group A, group B and group C, and the differences were statistically significant(P<0.05). Compared with each other between groups, response ASSR thresholds of group C was higher than those of group A(P=0.003) and group B(P=0.015) at 500 Hz, while response ASSR thresholds of group C was higher than group A at 1 000 Hz(P=0.010) and 2 000 Hz(P<0.001), and there was no statistical difference at 4 000 Hz. Conclusion:The incidence of hearing loss in GJB2 gene p.V37I mutation increased with age, and the degree of hearing loss increased, the hearing progression was mainly 500, 1 000 and 2 000 Hz suggesting regular follow-up and alert to hearing changes.

Objective:To explore the feasibility of the multiple-choice auditory graphical interactive check(MAGIC) screening module in childhood hearing screening in children aged 3 to 6 years. Methods:A hearing screening was conducted on 366 children(732 ears) aged between 3 and 6 years. The screening methods included MAGIC, DPOAE, and acoustic immittance.The cooperation, screening time, pass rate, and correlation of the three screening methods were compared. Results:There was a statistically significant difference in the degree of cooperation among the three screeningmethods(P=0.004).The MAGIC pure tone screening method was 98.6%, the screening DPOAE was 99.5%,and the acoustic immittance screening was 100%. For the screening duration, the MAGIC pure tone screening method was(116.3±59.1)s, the screening DPOAE was(27.2±19.7)s, and the acoustic impedance screening was(24.6±14.6)s. There was a significant statistical significance differences among the three or two groups(P<0.01). The passing rates of MAGIC pure tone screening,screening DPOAE and acoustic immittance screening were 64.7%, 65.4%, and 69.3%, respectively, and there was no significant statistical difference among the three or two groups(P>0.05). There was no significant difference between MAGIC pure tone screening method and screening DPOAE(P=0.827>0.05), and acoustic impedance(P=0.653>0.05), while the difference between screening DPOAE and acoustic impedance was statistically significant(P<0.01). Conclusion:MAGIC pure sound screening method has good feasibility, can comprehensively reflect the hearing level of screened children, and can be promoted for hearing screening in children aged between 3 and 6 years.

Objective:To explore the hearing changes of children with different genotypes of SLC26A4 with enlarged vestibular aqueduct(EVA) using the linear mixed effect model(LMM), providing evidence for the risk prediction of progressive hearing loss. Methods:A total of 48 children with EVA diagnosed in our hospital from January 2017 to January 2024. All subjects underwent two or more auditory tests. According to the results of deafness gene screening and sequencing, the genotypes are divided into: type A: homozygous mutation of c. 919-2A>G, type B: compound heterozygous or heterozygous mutation containing c. 919-2A>G, and type C: no mutation site of c. 919-2A>G of SLC26A4 gene. LMM was used to analyze the hearing thresholds change of 500 Hz, 1 000 Hz, 2 000 Hz, 4 000 Hz and the average in children with different genotypes with age. Results:A total of 92 ears, 314 audiograms of 48 children were included, the median number of audiograms was 3, the median age of initial diagnosis was 4 months, and the median follow-up time was 13 months. According to LMM, the standard deviation of random effects between patients and ears was large. There was no significant difference in hearing thresholds of different frequencies and the average in genotype A, genotype B, and genotype C, indicating that genotype had no effect on hearing threshold. There is an interaction between age and genotype. Taking genotype C as the reference, children with genotype B had the lowest increase in 500 Hz, 1000 Hz, and the average hearing threshold, followed by type A. Conclusion:EVA children exhibit substantial inter-individual/ear hearing threshold variability. Low-frequency thresholds progress slower than high frequencies. Genotype modulates progression rates, with wild-type(Type C) demonstrating fastest deterioration, supporting personalized auditory monitoring strategies.

ObjectiveTo investigate the possible mechanism of modified Gegen Qinlian Decoction (葛根芩连汤) in treatment of ulcerative colitis (UC) from the view of intestinal mucosal epithelial barrier damage and epithelial mesenchymal transition. MethodsSixty male C57BL/6J mice were divided into blank group, model group, western medicine control group, and low-, medium-, and high-dose modified Gegen Qinlian Decoction groups, with 10 mice in each group. Except for the blank group, 3% dextran sodium sulfate (DSS) was used to induce colitis model by free drinking for 7 days, and on the first day of modelling, 6, 12, and 24 g/(kg·d) of modified Gegen Qinlian Decoction were given to the low-, medium-, and high-dose groups respectively, 5-aminosalicylic acid (5-ASA) 100 mg/(kg·d) given by gavage to western medicine control group, and 10 ml/kg distilled water were given to blank and model group by gavage, once a day for 7 days. Body mass of mice was recorded and disease activity index (DAI) scores were performed daily. The mice were anesthetized after 24h of the last administration and the colon was taken to observe the length of colon, HE staining was applied to observe the damage of colonic mucosa and score pathological states, Masson staining to detect the deposition of colonic collagen fibers, immunofluorescence to observe the distribution of F-actin in colonic mucosal epithelium, and immunohistochemistry to detect the expression of tight junction protein ZO-1, Occludin, E-cadherin and Vimentin. ResultsCompared with the blank group at the same time, the percentage of body mass of mice in the model group on day 7 of modelling significantly reduced and the DAI score was significantly increased (P<0.01); compared with the model group at the same time, the body mass of mice in the western medicine control group and all of modified Gegen Qinlian Decoction groups decreased, and the DAI scores of mice in the western medicine control group and the high-dose modified Gegen Qinlian Decoction group decreased (P<0.05 or P<0.01); compared with the same time of mice in the low-dos Gegen Qinlian Decoction group, the body mass of mice in the high-dose Gegen Qinlian Decoction group and the western medicine control group significantly elevated (P<0.05). Compared with the blank group, the length of the colon of mice in the model group was significantly shortened, the pathological score and the percentage of collagen area were significantly increased, the average fluorescence intensity of F-actin was reduced, the protein levels of ZO-1, Occludin and E-cadherin in the colon tissue decreased, and the protein level of Vimentin elevated (P<0.01). Compared with the model group, the length of colon significantly increased, patholo-gical score, collagen area percentage decreased, ZO-1, Occludin, E-cadherin protein levels increased and Vimentin levels decreased in all medicated groups; the average fluorescence intensity of F-actin increased in the western medicine control group and the middle- and high-dose Gegen Qinlian Decoction groups (P<0.05 or P<0.01). Compared with the low-dose Gegen Qinlian Decoction group, the proportion of collagen fibre area in the middle-dose Gegen Qinlian Decoction group and the western medicine control group reduced; the mean fluorescence intensity of F-actin increased in the middle-dose Gegen Qinlian Decoction group; the protein levels of ZO-1 and E-cadherin increased in the western medicine control group, and the protein levels of ZO-1 increased in the high-dose Gegen Qinlian Decoction group (P<0.05). Compared with the medium-dose Gegen Qinlian Decoction group, the protein levels of ZO-1 elevated in the high-dose Gegen Qinlian Decoction group (P<0.05). Comapred with the high-dose Gegen Qinlian Decoction group, level of E-cadherin and Vimentin protein of the western medicine control group increased (P<0.05). ConclusionModified Gegen Qinlian Decoction was able to reduce colonic inflammation and mucosal barrier damage and inhibit the process of epithelial mesenchymal transition in mice models of ulcerative colitis, which may be one of its action mechanisms .

OBJECTIVE To analyze the difference of genotypes and hearing phenotypes in infants with biallelic allele variant in GJB2,and to provide reference for clinical practice. METHODS One hundred and forty-two subjects with biallelic allele variant in GJB2 were recruited in Beijing Tongren Hospital from August 2012 to March 2024. All subjects received universal newborn hearing screening(UNHS),neonatal deafness genetic screening and audiological tests. The subjects were divided into three groups according to the genotypes:T/T groups(truncated/truncated mutations,59 cases),T/NT group(truncated/non-truncated mutations,50 cases) and NT/NT group(non-truncated/non-truncated mutations,33 cases). Three groups of genotypes,newborn hearing screening results,age at first diagnosis and hearing diagnosis results were analyzed. RESULTS The homozygous mutation of c.235delC/c.235delC was the dominant in T/T group(57.63%),the compound heterozygous mutation of c.235delC/c.109G>A was the dominant in T/NT group(74.00%),and the homozygous mutation of c.109G>A/c.109G>A was the dominant in NT/NT group(96.97%). The overall refer rate of UNHS was 80.28%,and the refer rate of T/T group was 89.83%,which was significantly higher than that of T/NT group 70.00%(P=0.009). The age of first diagnosis of 142 cases was (3.70±1.56) months,there was no significant difference between the three groups(P>0.05). In 142 cases,104 cases with hearing loss accounted for 73.24%,38 cases with normal hearing accounted for 26.76%. The proportion of confirmed hearing loss in T/T group was 100.00%,which was significantly higher than that in T/NT group 52.00%(P<0.001) and NT/NT group 57.58%(P<0.001). In side of hearing loss,of the 104 patients with hearing loss,86 cases(82.69%) had bilateral hearing loss and 18 cases(17.31%) had unilateral hearing loss. The proportion of bilateral hearing loss in T/T group was 100.00%,which was significantly higher than that in T/NT group 57.69%(P<0.001) and NT/NT group 63.16%(P<0.001). Among 190 ears of 104 patients with hearing loss,the degree of hearing loss was predominantly mild to moderate(63.16%),followed by profound(24.74%) and severe(12.10%). Among them,the T/T group was mainly marked by severe to profound hearing loss(58.47%),while both the T/NT group and the NT/NT group were mainly characterized by mild hearing loss(58.54% and 74.19%),and the differences among the three groups were statistically significant(P<0.001). CONCLUSION In the T/T group,all patients were diagnosed as bilateral hearing loss at first diagnosis,and was mainly severe and profound hearing loss. The bilateral and unilateral hearing loss were 52.00% and 57.58% in the T/NT group and NT/NT group at first diagnosis respectively,and was mainly mild hearing loss.

Objective:To analyze the hearing phenotypes of p. V37I homozygote and compound heterozygote mutation in GJB2 gene, and to provide basis for genetic counseling. Methods:Fifty-three subjects with p. V37I homozygote and compound heterozygote mutation were recruited at Department of Otolaryngology Head and Neck Surgery, Beijing Tongren Hospital from January 2023 to March 2024. All subjects received universal newborn hearing screening(UNHS), 23-site chip neonatal deafness genetic screening and audiological tests, including ABR, acoustic immittance, DPOAE, ASSR. The results of newborn hearing screening and hearing diagnosis were compared between homozygous mutation group of 30 cases and compound heterozygous mutation group of 23 cases. Results:In 53 cases, the overall refer rate of UNHS was 64.15%(34/53), the refer rate of homozygous mutation group was 80.00%(24/30), which was higher than that of compound heterozygous mutation group(43.48%, 10/23), the difference between the two groups was statistically significant(P<0.05). Three subjects with p. V37I compound heterozygous mutation had passed UNHS and diagnosed with unilateral mild hearing loss. The average age of diagnosis of 53 cases was (3.77±1.40) months, 25 cases with hearing loss accounted for 47.17%, including 13 cases with unilateral, 12 cases with bilateral, 28 cases with normal hearing accounted for 52.83%. There was no significant difference between homozygous mutation group(56.67%, 17/30) and compound heterozygous mutation group(34.78%, 8/23) in the proportion of confirmed hearing loss(P>0.05). Among 37 ears of 25 patients with hearing loss, the proportion of mild, moderate and profound hearing loss were 70.27%(26/37), 27.03%(10/37) and 2.70%(1/37), respectively. The hearing loss degree of the homozygous mutation group and the compound heterozygous mutation group were mainly mild, accounting for 70.37%(19/27) and 70.00%(7/10) respectively. There was no significant difference between the two groups in the distribution of hearing loss degree(P>0.05). Conclusion:The probability of hearing loss was 47.17% in infants of GJB2 gene p. V37I homozygote and compound heterozygote mutation, mainly mild hearing loss. There was no difference in the probability of hearing loss and the distribution of hearing loss degree between the two groups. Patients with p. V37I homozygous and compound heterozygous mutation currently diagnosed as normal hearing need continuous clinical follow-up.
