To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen， kidney essence deficiency， liver constraint transforming into fire， and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen （TE 21）， Tinggong （SI 19）， Tinghui （GB 2）， Shenmai （BL 62） to regulate qi and blood， and supporting with Baihui （GV 20）， Yintang （EX-HN 3）， Taichong （LR 3）， and Yanglingquan （GB 34） to soothe the liver， resolve constraint， and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction （益气聪明汤） and Tongqi Powder （通气散）， and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder （温清散） to navel moxibustion.

Objective To analyze the virus subtypes, molecular evolutional and molecular transmission network features of the first confirmed mpox case in Huai’an City, Jiangsu Province, so as to provide insights into understanding of the transmission and evolution dynamics of mpox virus and formulation of the mpox control strategy in the city. Methods Genomic DNA was extracted from swabs of the first confirmed mpox case’s skin lesions in Huai’an City, and the amplicon sequencing library was constructed using the hypersensitive mpox virus whole-genome capture kit. High-throughput sequencing was performed using the GridION X5 nanopore sequencer on the Nanopore sequencing platform, and single nucleotide polymorphism (SNP) analysis of mpox virus genome sequences was performed following sequence assembly. In addition, phylogenetic analysis, genetic genealogy and molecular traceability analysis were performed. Results The virus whole genome sequence of the first confirmed mpox case was successfully obtained by high-throughput sequencing, with a full length of 197 182 bp, and was named hMpxV/China/JS-HA01/2023, which belonged to the clade IIb (West African clade) lineage B.1.3. Compared with the mpox virus reference sequence MPXV-M5312_HM12_Rivers-001 (GenBank accession number: NC_063383), the genome sequence of the Huai’an virus isolate carried 86 SNPs, including 40 SNPs in the coding region as non-synonymous mutations and 73 SNPs as nucleotide mutations caused by APOBEC3 (APOBEC3). Of the 97 mpox virus gene sequences, 79 sequences were included in the molecular network (81.44%), and the threshold of the genetic distance accessed to the network was 0.35/10⁵. There were two large molecular transmission clusters and one scattered cluster in the molecular transmission network of the mpox virus, andthehMpxV/China/JS-HA01/2023 sequence was located in the large cluster. The 97 gene sequences formed 92 haplotypes, including three shared haplotypes Hap_4, Hap_6 and Hap_38, and an exclusive haplotype Hap_1 of hMpxV/China/JS-HA01/2023 generated from mutation of the exclusive haplotype Hap_43, while the exclusive haplotype Hap_43 was generated from mutation of the shared haplotype Hap_38. Conclusions The whole genome sequence of the mpox virus isolated from the first confirmed mpox case in Huai’an City has been successfully obtained, and the molecular evolutionary and molecular transmission network characteristics of the virus have been preliminarily understood.

Objective To analyze the performances of electronic portal imaging device (EPID) in mechanical and dosimetry responses,and to investigate the feasibility of adopting EPID as a daily quality assurance (QA) equipment. Methods The EPID of Trilogy linear accelerator was tested for mechanical position repeatability and dose linear response. Then,a group of special fields were edited manually for simulations of field translation and symmetry deviations,and the sensitivities of EPID and MyQA Daily to field translation and symmetry deviations were evaluated,and moreover,the linear correlation between the set value and the measured value was analyzed. Finally,daily QA was conducted with EPID and MyQA Daily for 30 consecutive days,and the measurement results and time consumption were analyzed. Results The maximum deviation of EPID position repeatability was 0.4 mm,and the dose response was linearly correlated (R2>0.999). The symmetry deviation test results showed that both of EPID and MyQA Daily were capable to effectively detect the 0.2％ offset in symmetry,and a linear correlation was demonstrated between the set value and the measured results (R2>0.995). In translation test,the linear correlation of EPID was more explicit than that of MyQA Daily (R2=0.992 vs R2=0.976). In daily QA,all the measured results of EPID and MyQA Daily were within the clinic acceptance tolerance. Moreover,the mean value of Y-directional symmetry and flatness measured by EPID was approximately 1.00％ larger than MyQA Daily. The average time required by EPID was 50 s less than MyQA Daily[(129.97±4.16) s vs (184.53±4.23) s]. Conclusion EPID can be served as a reliable and efficient daily QA equipment for linear accelerator. However,it is not capable to be used as a criterion for evaluating linear accelerator performance.

The novel coronavirus(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2),classified as a single-stranded RNA virus,replicates and transcribes its genome through the action of an RNA-dependent RNA polymerase,which is itself comprised of numerous non-structural pro-teins(non-structural proteins,Nsps).The present study delineates the development of a detection system founded on a bicistronic reporter plasmid in conjunction with an array of Nsp plasmids,ai-ming to investigate the influence of SARS-CoV-2 Nsps on the virus's replication and expression profiles.Specifically,a bicistronic reporter gene plasmid along with twelve distinct Nsp plasmids(encompassing Nsp3C-Flag,Nsp4,Nsp6-Nsp10,Nsp12-Nsp16)were meticulously constructed via molecular cloning techniques.The successful expression of these Nsps was subsequently confirmed through Western blot analysis.Initially,the activity of the RNA-dependent RNA polymerase was assessed by co-transfection of the reporter plasmid with Nsp12,in the presence of its auxiliary fac-tors Nsp7 and Nsp8,with careful regulation of the co-transfection ratio,culturing temperature,and the timing of activity determination for the triad of Nsp plasmids.The normalized NLuc fluorescein value,in reference to the FLuc fluorescein value of the housekeeping gene,served as a metric for determining the polymerase activity.Building upon this foundation,the co-transfection concentra-tions of Nsp9-16 were fine-tuned,followed by the incremental addition of varying doses of Nsp3C,Nsp4,and Nsp6,to further elucidate the activity of RNA-dependent RNA polymerase(RdRp).The findings indicated that upon transfection with varying ratios of Nsp7,Nsp8,and Nsp12 at a propor-tion of 1∶8∶24,the polymerase activity was markedly elevated compared to the control group,with a statistical significance level(P＜0.001).Furthermore,in the absence of Nsp3,Nsp4,and Nsp6,the inclusion of Nsp10-16 substantially augmented the activity of the RdRp,particularly in scenarios where Nsp9 was not introduced,achieving statistical significance(P＜0.001).In the pres-ence of Nsp3 and Nsp4,the RdRp activity was augmented further upon the addition of Nsp9,reac-hing a level of significance(P＜0.05).The data imply that Nsp9 is capable of enhancing the RdRp activity of SARS-CoV-2 exclusively in the context of Nsp3 and Nsp4 coexistence,suggesting that the stimulatory influence of Nsp9 on viral replication may be contingent upon the formation of double-membrane vesicles.

Deep intronic variants refer to genetic variants located within intronic regions that are more than 100 base pairs away from exon-intron boundaries. These variants have historically been overlooked in the genetic testing of hereditary skeletal muscle diseases. Conventional genetic testing methods, such as whole exome sequencing, primarily focus on coding regions and exon-intron junctions [±(50-200) bp], thereby failing to detect abnormalities in extensive intronic regions. Furthermore, assessing the pathogenicity of identified deep intronic variants remains challenging. Recent studies have demonstrated that certain hereditary myopathies can be attributed to deep intronic variants. The underlying pathogenic mechanisms include the formation of pseudoexons, activation of cryptic splice sites, and disruption of transcriptional regulation. Although deep intronic variants can be detected using whole-genome sequencing or third-generation long-read sequencing technologies, these approaches are associated with high costs and difficulties in interpreting the results. Clinically, a combination of multiple detection methods is necessary for comprehensive analysis. Integrating functional validation techniques, such as RNA sequencing and minigene assays, facilitates the interpretation of deep intronic variants and enhances diagnostic yield, thereby offering novel insights into the diagnosis and management of hereditary myopathies.

Objective:To analyze the short-and medium-term clinical outcomes of Mako robotic-assisted posterior-lateral approach in complex primary total hip arthroplasty (THA).Methods:A retrospective case series analysis was conducted on 29 patients with complex hip conditions who underwent Mako robotic-assisted posterior-lateral approach at Department of Orthopaedics, the Second Affiliated Hospital of Zhejiang University School of Medicine from November 2020 to December 2024. The patient cohort included 14 cases of developmental dysplasia of the hip, 8 cases of ankylosed hip, 3 cases of traumatic hip arthritis, 3 cases of sequelae of purulent hip arthritis, and 1 case of synovial chondromatosis. There were 12 males and 17 females, with an age of (62.3±9.4) years (range:44 to 79 years). Surgical time, intraoperative blood loss, vascular and nerve injury, postoperative infection, and other complications were recorded. Preoperative and postoperative lower limb length discrepancy, combined offset difference (ΔCO), acetabular abduction angle, and acetabular anteversion angle were measured. The Harris hip score was recorded at regular follow-ups. Data comparison was conducted using the paired sample t-test. Results:All patients successfully underwent surgery with the Mako robotic system. The surgical time was (107.6±41.5) minutes (range:50 to 235 minutes), and the intraoperative blood loss was (165.5±147.7) ml (range:50 to 800 ml). All patients were followed up for a duration of (27.3±16.7) months (range:3 to 51 months). The planned intraoperative acetabular cup abduction angle was 40.1°±1.6° (range: 36° to 45°), and the measured postoperative acetabular cup abduction angle was 40.2°±3.5° (range: 33° to 54°), with no significant difference ( t=0.231, P=0.819). The planned intraoperative acetabular cup anteversion angle was 19.1°±3.9° (range: 15° to 25°), and the measured postoperative acetabular cup anteversion angle was 18.5°±3.4° (range: 10° to 26°), with no significant difference ( t=1.792, P=0.084). The difference in length of both lower limbs was (-17.6±15.0) mm (range:-50 to 10 mm) before operation and (-1.5±16.0) mm (range:-33 to 53 mm) after operation ( t=6.282, P<0.01)(positive values indicate that the surgical side is longer than the contralateral side). The ΔCO was (4.1±12.0) mm (range:-18 to 30 mm) before operation and (-2.2±13.3) mm (range:-44 to 17 mm) after operation, with statistically significant difference ( t=2.635, P=0.014). One patient experienced vascular injury with embolism postoperatively, while no other complications were observed in the remaining patients. No loosening, dislocation, or fracture of the prosthesis was noted during the follow-up period. The Harris function score was improved from (47.1±8.3) points(range:15 to 62 points) preoperatively to (73.0±5.5) points(range:57 to 83 points) at the three-month postoperative follow-up ( t=22.630, P<0.01). Conclusion:The use of Mako robotic assistance in complex total hip arthroplasty can enhance the accuracy of prosthesis placement, minimize lower limb length discrepancy, and improve hip joint function.
