Objective:This study introduces a novel segmented and layered thoracic laminoplasty technique for the treatment of thoracic spinal stenosis (TSS) caused by ossification of the posterior longitudinal ligament (OPLL) and ligamentum flavum (OLF). The goal is to simplify the surgical procedure, improve safety, reduce iatrogenic injuries, and validate its clinical outcomes through follow-up.Methods:A retrospective analysis was conducted on 23 patients (10 males, 13 females; mean age 58.83±12.01 years) treated at Taizhou People's Hospital Affiliated to Nanjing Medical University from January 2018 to December 2023. Transverse grooves were created at the superior and inferior vertebral pedicle levels, utilizing the intervertebral ligamentum flavum as a segmental demarcation reference. Partial removal of the distal lamina and medial of the inferior articular process was performed through a cortical window. Under direct visualization, complete removal of ossified ligamentum flavum, proximal portion of lamina, superior articular process. The treatment effect was evaluated by clinical symptoms, signs, Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS), imaging results (CT and MRI) and complications before or after surgery.Results:All 23 procedures were successfully completed with a mean operative duration of 180(150, 220) min, the surgical time for 71 segments were 67.5(53.8, 120.0) minutes and intraoperative blood loss of 200(100, 300) ml, demonstrating a low intraoperative dural tear rate of 8.70% (2/23). Postoperative imaging (CT/MRI) confirmed adequate decompression in all cases, with significant symptom improvement at final follow-up 21(9, 39) months: 47% (7/15) of patients achieved marked relief of lower limb numbness, 82% (14/17) showed substantial motor recovery, and 54% (7/13) exhibited improved gait stability. Functional outcomes revealed significant enhancements, with JOA scores increasing from 8(6, 8) preoperatively to 9(8, 10) postoperatively ( P<0.05; 43.80% improvement rate) and VAS scores decreasing from 6(5, 7) to 2(1, 4) ( P<0.05). The complications were two dural tears and one suture reaction. Conclusions:Ultrasonic osteotome-assisted segmented layered laminectomy is a safe, effective, and straightforward technique for treating thoracic spinal stenosis caused by OPLL and OLF. It offers shorter operative times, minimal complications, and significant clinical improvement, making it a promising technique for broader clinical adoption.

Apical microsurgery is accurate and minimally invasive, produces few complications, and has a success rate of more than 90%. However, due to the lack of awareness and understanding of apical microsurgery by dental general practitioners and even endodontists, many clinical problems remain to be overcome. The consensus has gathered well-known domestic experts to hold a series of special discussions and reached the consensus. This document specifies the indications, contraindications, preoperative preparations, operational procedures, complication prevention measures, and efficacy evaluation of apical microsurgery and is applicable to dentists who perform apical microsurgery after systematic training.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To explore the diagnostic reference level(DRL)of computed tomography(CT)based on size-specific dose estimate(SSDE)for child's head,and estimate the SSDE by using tube current time production.Methods:The CT data of head of 1259 pediatric patients who underwent CT examination in Children's Hospital of Nanjing Medical University from January 2023 to December 2023 were retrospectively collected.They were divided into six groups according to different ages:<6 months group,6 months to<1 year group,1 to<3 years group,3 to<6 years group,6 to<12 years group,and≥12 years group.Additionally,they were divided into five groups based on body size:<12.5 cm group,12.5 to<14 cm group,14 to<15 cm group,15 to<16 cm group,and≥16 cm group.The volume CT dose index(CTDIVOL),tube current time production(mAs),left and right diameter(LRD),area(AROI)and CT value(CTROI)of region of interest of different age groups were respectively measured and recorded.The water equivalent diameter(DW),conversion factor(f H16)and SSDE based on DW(SSDEDW)were calculated.The DRLs distribution based on age and body size was analyzed by statistic method,and the correlation between DW and mAs was analyzed by regression analysis,and a regression model between SSDEDW and mAs was further established.The intra-group correlation coefficient(ICC)was used to analyze the consistency.Results:In DRLs of various age groups,the CTDIVOL range and SSDEDW range were respectively(12.32 mGy-21.66 mGy)and(13.47 mGy to 17.83 mGy).In the DRL of various body size groups,the CTDIVOL range and SSDEDW range were(13.52 mGy-21.86 mGy)and(13.91 mGy-17.92 mGy).In different ages group of pediatric patients,the range of deviation rates of local DRL(LDRLs)value of radiation dose on head of CTDIVOL value to SSDEDW was-8.54%-21.48%.There were strong positive correlations between DW and mAs at 100 and 120 kVp(r=0.96,0.89,P<0.001),respectively.There was stronger consistency between the calculated value by using SSDEDW and actual measurement value by using sAs(ICC=0.98).Conclusion:SSDEDW can more accurately reflect radiation dose,and SSDEDW can be more quickly calculated to control the radiation dose by using the regression models between SSDEDW and mAs.

Objective To explore the application values of fixed tube current based on head circumference(HC)in children's head CT examinations.Methods A total of 573 children's head CT imaging data were collected retrospectively,the tube current and HC were recorded.Pearson's correlation analysis was used to determine the relationship of tube current with HC,counted the median tube current values of each group based on HC and used them as the prefixed tube current.Seventy-two children were prospectively collected.According to the random number table method,the children were divided into the control group and the experimental group,with 35 cases in the control group and 37 cases in the experimental group.The control group used automatic exposure control(AEC)technology for tube current,while the experimental group used the median value of tube current corresponding to HC group-ing.The difference in radiation doses and image qualities between the two groups was compared.Results Pearson analysis of 573 retrospec-tive cases showed that the correlation between HC and tube current was considerably strong(r=0.95,P＜0.001).The median tube current values of each group based on HC were 70-130 mAs.There were statistically significant differences in CTDIvol.16 and SSDEDW based on water equivalent diameter(DW)between the two groups(t=-11.27,2.81,P＜0.05).Compared with the control group,CTDIvol.16 and SSDEDW in the experimental group decreased by 10.83％and 12.59％respectively.There were no statistically signifi-cant differences in signal-to-noise ratio(SNR)between the two groups(t=-1.26,P＞0.05)and there were also no statistically significant differences in the subjective evaluation of images(Z=-0.45,P＞0.05).Conclusion Measuring children's HC before examination and setting the fixed tube current corresponding to HC grouping can reduce radiation doses while maintaining image qualities.
