It's a hard but imperative research subject for postgraduate to study medical English in TCM colleges.For more than 3 years,Nanjing University of TCM has obtained good effect in such a field and their practices include adopting original edition of textbooks,selecting medical professionals who are good at English as teachers rather than English teachers who have some medical knowledge.Our teaching methodology is continuous,large volume fast reading.

In order to realize the sustained education concept in clinical medical English teaching,several measures were taken in the first clinical medical college of Nanjing University of Traditional Chinese Medicine,such as training the teaching staff,using original textbooks and redesigning the curriculum.Particularly the tutorial system was introduced to the education frame.The teaching and research section of clinical medical English explored the new teaching routes for postgraduates in traditional Chinese medicine university.

Objective To investigate the effect of 1α, 25-dihydroxyvitamin D3 [1α,25-(OH)2 D3] on tumor necrosis factor-α ( TNF-α) induced activation of human umbilical vein endothelial cells ( HUVECs ) . The mechanism involved in this process was also studied. Methods HUVECs were cultured and treated with TNF-α( 40 ng/ml), 1α,25-(OH)2D3(10-8 mol/L), and SN50 as indicated. Vascular cell adhesion molecule (VCAM) and E-selectin were used as markers of endothelial activation, which were detected by Western blotting and realtime PCR (RT-PCR). NF-κB signaling pathway was investigated to study the mechanism. Western blotting, RT-PCR, immunofluorescence assay, and chromatin immunoprecipitation ( ChIP ) method were used to evaluate the effects of 1α,25-( OH) 2 D3 on its early activation, nuclear transport, and binding to VCAM and E-selectin promoters. Results (1) Western blotting and RT-PCR showed that TNF-α could significantly up-regulate the expression of VCAM and E-selectin in HUVECs, which can be inhibited by specific NF-κB blocker SN50. 1α,25-( OH) 2 D3 down-regulated the expression of VCAM and E-selectin induced by TNF-α. ( 2 ) Western blotting showed that TNF-α induces I-κBαphosphorylation, thereby activating NF-κB p65 subunit. Immunofluorescence showed that 1α, 25-( OH ) 2 D3 significantly inhibited the nuclear translocation of NF-κB p65 subunit. ChIP analysis revealed that 1α,25-( OH) 2 D3 inhibited the binding of NF-κB p65 to VCAM and E-selectin promoters and thus affected gene expression. Conclusions TNF-αenhanced the expression of E-selectin and VCAM in HUVECs via NF-κB signaling pathway. 1α,25-( OH) 2 D3 may inhibit NF-κB early activation, nuclear transport and the binding of NF-κB p65 to VCAM and E-selectin promoters, thereby inhibiting TNF-α-induced endothelial cell activation.

OBJECTIVE To compare the metabolomic characteristics of stage T1 papillary thyroid carcinoma(PTC)and nodular goiter(NG),and the relationship between metabolites and lymph node metastasis of PTC.METHODS Serum samples were collected from 60 patients with stage T1 PTC and 30 patients with NG who underwent thyroidectomy at the Department of Otolaryngology Head and Neck Surgery,Civil Aviation General Hospital between September 2021 and April 2022.The PTC group was divided into the N+ group with lymph node metastasis and the N-group without lymph node metastasis according to the presence or absence of lymph node metastasis.The serum metabolites of the N+ and N-groups and the PTC and NG groups were compared and analyzed using an ultra-performance liquid chromatography-mass spectrometry(UPLC-Q-Exactive-MS)coupled platform,and principal component analysis(PCA),partial least squares discriminant analysis(PLS-DA),and orthogonal partial least squares discriminant analysis(OPLS-DA)was performed using SIMCA-P 14.1 software.OPLS-DA modeling,combined with FDR-corrected Mann-Whitney-Wilcoxon test results and metabolite difference multiples in the two groups undergoing comparison,etc.to screen for potential small molecule metabolic markers,and to establish a joint diagnostic model by binary logistic regression analysis.RESULTS There were no significant differential metabolites between the N+ group with lymph node metastasis and the N-group without lymph node metastasis.Seven differential metabolites were found between PCA patients and NG patients,and the five relevant metabolic pathways were the pentose phosphate pathway,pentose and glucuronide interconversion,glycolysis/gluconeogenesis,fructose,and mannose metabolism,and fatty acid biosynthesis.The differential metabolite with an area under the ROC curve>0.9 was D-glyceraldehyde 3-phosphate,and another N-undecanoylglycine,uronic acid,and the area under the ROC curve for three metabolites,N-undecanoylglycine,uric acid,and triiodothyronine glucuronide,was>0.8.CONCLUSION PTC patients differed from NG patients mainly in glucose metabolism and lipid metabolism,and D-glyceraldehyde 3-phosphate could be distinguished from NG patients with the aid of N-undecanoylglycine,uric acid,and triiodothyronine glucuronide,combined with imaging findings.Also,no significant differences in serum metabolites were found in the N+ group compared with the N-group,and the presence or absence of lymph node metastases did not affect serum metabolites in patients with stage T1 PTC.

Objective: This study aims to investigate the anatomical relationship among the nerve roots, intervertebral space, pedicles, and intradural rootlets of the cervical spine for improving operative outcomes and exploring neuroventral decompression approach in posterior endoscopic cervical discectomy (PECD). Methods: Cervical computed tomography myelography imaging data from January 2021 to May 2023 were collected, and the RadiAnt DICOM Viewer Software was employed to conduct multiplane reconstruction. The following parameters were recorded: width of nerve root (WN), nerve root-superior pedicle distance (NSPD), nerve root-inferior pedicle distance (NIPD), and the relationship between the intervertebral space and the nerve root (shoulder, anterior, and axillary). Additionally, the descending angles between the spinal cord and the ventral (VRA) and dorsal (DRA) rootlets were measured. Results: The WN showed a gradual increase from C4 to C7, with measurements notably larger in men compared to women. The NSPD decreased gradually from the C2–3 to the C5–6 levels. However, the NIPD showed an opposite level-related change, notably larger than the NSPD at the C4–5, C5–6, and C7–T1 levels. Furthermore, significant differences in NIPD were observed between different age groups and genders. The incidence of the anterior type exhibited a gradual decrease from the C2–3 to the C5–6 levels. Conversely, the axillary type exhibited an opposite level-related change. Additionally, the VRA and DRA decreased as the level descended, with measurements significantly larger in females. Conclusion A prediction of the positional relationship between the intervertebral space and the nerve root is essential for the direct neuroventral decompression in PECD to avoid damaging the neural structures. The axillary route of the nerve root offers a safer and more effective pathway for performing direct neuroventral decompression compared to the shoulder approach.
