Methods: The median sagittal diameter and transverse diameter of the spinal canal from C2 to C7 were measured on CT images. The ratio of the median sagittal diameter to the transverse diameter was calculated. Accordingly, the spinal canal shape of each segment was classified into four, and the specific criteria of lunar phase classification were determined through linear discriminant analysis based on the ratio of the median sagittal diameter to the transverse diameter. The inter-rater reliability of the classification was explored using Kappa coefficients. Finally, the morphology of the different segments of the cervical spinal canal in healthy volunteers was revised and compared. Results: According to the ratio of the median sagittal diameter and the transverse diameter of the cervical spinal canal, the lunar phase classification of the cervical bony spinal canal was determined as follows: full-moon >0.65, 0.55< convex-moon ≤0.65, 0.46≤ quarter-moon ≤0.55, and residual-moon <0.46. The Kappa values of C2–C7 were 0.851, 0.958, 0.823, 0.927, 0.793, and 0.946, and the Kappa value of all C2–C7 segments was 0.854 that mainly presented two forms of full-moon (76.5%) and convex-moon (23.0%). A quarter-moon spinal canal was mainly distributed in C3, C4, C5, and C6; a residual-moon spinal canal was mainly distributed in C4 and C5; and the morphological distribution of C4 and C5 were similar (p>0.05). The frequency of the spinal canal of the residual-moon type was the highest, and the full-moon (6.5%) and residual-moon (7.5%) types of C7 were rare. Conclusions The morphological classification of the cervical spinal canal was established to present anatomical variations. The classification showed good inter-rater reliability.

Objective:To investigate the diagnostic efficacy of MRI-based or CT-based measurements and the combined evaluation methods for preoperative bone quality assessment in patients with cervical degenerative diseases.Methods:Patients who underwent spine surgery for cervical degenerative diseases at the Department of Orthopedics, Huashan Hospital, Fudan University from September 2020 to March 2022 with available preoperative X-ray, CT, MRI and dule energy X-Ray absorptiometry (DEXA) data were included in this study. Vertebral bone quality score (VBQ) based on MRI T1-weightedimages and CT Hounsfiled unit (HU) values of the cervical spine were measured, and a combined diagnostic formula based on the binary logistic regression was constructed. The patients were divided into normal bone mass (T≥-1.0) and osteopenia/osteoporosis groups (T<-1.0). The student's t-test and Chi-square test were performed for comparisons between groups. The Pearson correlation coefficient was also used to investigate the correlation between DEXA-T scores, cervical VBQ and CT HU values. In addition, receiver operating characteristic curve (ROC) were plotted to explore the diagnostic efficacy of VBQ, CT HU and their combined diagnosis. Meanwhile, the corresponding sensitivity and specificity were obtained. Results:A total of 71 patients were included in this study (17 in the normal group and 54 in the osteopenia/osteoporosis group). The student's t-test showed that VBQ (2.90±0.70 vs. 3.83±0.83, t=4.23, P<0.001) and CT HU values (370.26±85.38 vs. 295.20±67.96, t=3.73, P=0.002) were significantly different between the two groups. The area under the ROC curve (AUC) for VBQ and CT values of the cervical spine were 0.81 and 0.75, respectively, and the AUC for the combined diagnostic value constructed on the basis of both was 0.85. Applying VBQ scores alone had a diagnostic sensitivity of 80% and a specificity of 70%, and the combined diagnosis with VBQ and CT HU had a sensitivity of 90% and a specificity of 75%. Person correlation analysis showed a significant correlation between DEXA T value, cervical VBQ value and CT HU value. The detailed formula was: DEXA T score=-0.63×cervical VBQ+0.64 ( r=-0.55, P<0.001), CT HU value=-40.20×cervical VBQ+458.40 ( r=-0.45, P<0.001), DEXA T score=0.006×CT HU-3.47 ( r=0.45, P<0.001). Conclusion:This study confirmed the feasibility of using cervical VBQ values, CT HU values and combined diagnostics for preoperative bone density screening in patients with degenerative cervical spine diseases. This method allows surgeons to perform an initial preoperative bone density screening based on the patient's existing imaging data, and thus could aid in confirming the indication and scheme of surgery. The method could be a powerful tool for preoperative bone density assessment screening in patients with cervical degenerative diseases.

In recent years, with the development of neurointerventional techniques, transradial approach (TRA) has been able to meet most needs of neurointerventional procedures. Compared with tranfemoral approach (TFA), TRA can obviously reduce access-site complications, shorten hospital stays and improve patient satisfaction. However, due to the long learning curve, lack of radial-specific catheters, small artery diameter and specific vascular access-site complications, TRA development is relatively slow, and relevant domestic and foreign studies are still at initial stage. Therefore, this article mainly focuses on the anatomy, advantages and limitations, approaches of radial artery, and discuss the safety and feasibility of TRA in neurointerventional diagnosis and treatment, in order to provide more references for neurointerventionalists.

Objective: To explore the value of nanoparticles (CN) in lateral cervical lymph node mapping in papillary thyroid carcinoma using carbon. Methods: Thyroid cancer patients with suspicious lymph node metastasis but without typical signs of metastatic disease from March 2016 to November 2017 in Fudan University Shanghai Cancer Center were prospectively included in the cohort. Neck dissection was performed in all patients (compartmentsⅡ-Ⅴ). Suspicious lateral lymph node metastasis was identified using pre-operative ultrasound or computed tomography. CN were used for lymph node mapping during surgery. Results: A total of 70 surgeries were performed in 67 patients, among which 57 were found to have lateral lymph node metastasis (81.4%). The median number of CN-dyed lateral lymph nodes was 6. Compartment IV had the highest number of CN-dyed positive lymph nodes as well as the highest rate of metastasis, followed by compartmentⅢ. In compartmentsⅢandⅣ, the incidence of lymph node metastasis was significantly higher in the CN-dyed group than in the CN-undyed group (P<0.001). When the final pathology of neck dissection was set as the gold standard, lateral CN-dyed lymph node biopsy was found to have a sensitivity of 86.0%; its negative predictive value was 61.9% and its overall accuracy was 88.6%. Conclusions:Injection of CN during surgery was a potential method of mapping lateral lymph nodes in papillary thyroid carcinoma. CompartmentⅢ-ⅣCN-dyed lymph node biopsy had a satisfactory sensitivity and thus, served as a reasonable range for lymph node biopsy.

This article introduces the safety risks of the novel light-based home-use hair removal device, and analyzes the differences in regulation among China, the United States and the European Union. In China, household intense pulsed light hair removal devices will also be supervised in accordance with medical device regulations. Therefore, the safety standards adopted in the absence of specific regulations are no longer applicable to the new regulatory requirements. It is imperative to adopt the new standards available to home photoepilators, so as to ensure the safety and effectiveness of the approved devices.

Objective: To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO. Methods: Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×10⁹/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×10⁹/L. Results: A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×10⁹/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×10⁹/L) at 4^th week, 8^th week and 12^th week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×10⁹/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild. Conclusion Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.

To unravel the genetic mechanisms of disease and physiological traits, it requires comprehensive sequencing analysis of large sample size in Chinese populations. Here, we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative (CASPMI) project launched by the Chinese Academy of Sciences, including the de novo assembly of a northern Han reference genome (NH1.0) and whole genome analyses of 597 healthy people coming from most areas in China. Given the two existing reference genomes for Han Chinese (YH and HX1) were both from the south, we constructed NH1.0, a new reference genome from a northern individual, by combining the sequencing strategies of PacBio, 10× Genomics, and Bionano mapping. Using this integrated approach, we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1. In order to generate a genomic variation map of Chinese populations, we performed the whole-genome sequencing of 597 participants and identified 24.85 million (M) single nucleotide variants (SNVs), 3.85 M small indels, and 106,382 structural variations. In the association analysis with collected phenotypes, we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males. Moreover, significant genetic diversity in MTHFR, TCN2, FADS1, and FADS2, which associate with circulating folate, vitamin B12, or lipid metabolism, was observed between northerners and southerners. Especially, for the homocysteine-increasing allele of rs1801133 (MTHFR 677T), we hypothesize that there exists a "comfort" zone for a high frequency of 677T between latitudes of 35-45 degree North. Taken together, our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine.
