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 explore the correlation between changes in intestinal toxicity and changes in component composition of the Mongolian medicine Euphorbiae pekinensis Radix(EPR)before and after processing with milk.METHODS Mice were given 95%ethanol extract of raw EPR,milk-processed EPR and water-processed EPR by gavage.The purgative effect and intestinal inflam-matory toxicity changes of EPR before and after milk processing were investigated using the fecal water content and the levels of inflam-matory factors TNF-α and IL-1β in each intestinal segment of mice as indicators;LC-MS/MS was used to analyze the composition changes of the 95%alcohol extract of EPR before and after milk processing.RESULTS Compared with the blank group,the raw and water processed products of EPR could significantly increase the water content of mouse feces and the levels of TNF-α and IL-1β in each intestinal segment(P＜0.05);compared with the raw product group,all indicators in the milk processing group were significantly reduced(P＜0.05),while there was no significant difference in the water processing group,indicating that water processing cannot at-tenuate toxicity,and the auxiliary material milk is the key auxiliary material to reduce the toxicity of EPR.Mass spectrometry analysis results showed that a total of 50 components were identified in EPR,including 38 terpenoid components,6 phenolic acid components,and 6 other components.The content of each component decreased to varying degrees after milk processing.Principal component analy-sis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)were performed on the mass spectrum data of raw ma-terials and products,and it was found that the components of raw materials and products can be obviously clustered into 2 categories.13 differential components of raw materials and products were screened through t test,and 11 of which were terpene compo-nents,indicating that the composition of terpene components changed significantly after milk processing.17 components derived from EPR were detected in the residual liquid of milk excipients after processing,of which 16 were terpenoids,indicating that the terpenoid components of EPR were transferred to the excipient milk during the soaking and processing processes.CONCLUSION The toxicity of EPR is reduced and the purgative effect is alleviated after milk processing.The attenuation mechanism may be that during the milk soaking and processing processes,terpenoid components are transferred to the milk,and the content of toxic components in the decoc-tion pieces is reduced,thereby reducing the toxicity.

Objective To evaluate 99mTc-HYNIC-TOC somatostatin receptor and 131 I-MIBG imaging in clinical diag-nostic of pheochromocytoma and paraganglioma(PPGL).Methods This was a retrospective study.359 PPGL pa-tients diagnosed by pathology microscopy were included.The diagnostic sensitivity and influencing factors on 99mTc-HYNIC-TOC somatostatin receptor and 131 I-MIBG imaging were analyzed.Results The positive rate of 99mTc-HYN-IC-TOC somatostatin receptor scintigraphy was 57.7%(184/319)and 131I-MIBG imaging was 83.2%(232/279).The positive rates of 99m Tc-HYNIC-TOC somatostatin receptor imaging in the adrenal glands,retroperitoneum,head and neck,heart and mediastinum,pelvis and bladder were 53.3%,62.5%,95.0%,66.7%,50.0%and 11.0%respec-tively and the positive rates of 131I-MIBG imaging were 86.7%,88.5%,45.4%,50.0%,75.0%and 33.3%respec-tively.The positive rate of the two imaging did not showed difference among patients with different genetic back-grounds(SDH,VHL,RET mutations).The median maximum diameter of tumors was 4.4(3.0,6.1)cm.and the diag-nostic sensitivity of somatostatin receptor imaging and 131 I-MIBG imaging for larger tumors(≥4.4 cm)was signifi-cantly higher than those for the smaller tumor group(＜4.4 cm)(64.0%vs.51.3%;92.3%vs.74.1%)(P＜0.01).Tumors in 19 patients(5.3%)failed to uptake neither imaging method.Conclusions This is the largest PPGL cohort in China concerning 99m Tc-HYNIC-TOC somatostatin receptor imaging and 131 I-MIBG imaging.The sensitivity of 131 I-MIBG imaging is higher than that of 99m Tc-HYNIC-TOC somatostatin receptor imaging,but for some tumors,such as head and neck paraganglioma,the latter has obvious advantages.These two imagings technol-ogies are complementary and the choice of them should depend the individual situation of patients.

Nipah virus(NipahVirus,NiV)is a zoonotic virus that can cause encephalitis and severe respiratory symptoms in humans and animals,and is at risk of being introduced into China.At present,there are many factors related to the transmission of Nipah virus disease(NVD),but the actual effects of these factors are controversial.Therefore,with the help of meta-analysis,this paper aims to determine the current mortality and the main means of transmission of NVD,so as to pro-vide reference for the input of controlling Nipah virus disease and making emergency plans for pre-vention and control in our country.By searching the articles published in Pubmed,Embase,Web of knowledge,CNKI,VIP Chinese Sci-tech Journals Database and Wanfang Database up to December 31,2022,the literature of cross-sectional,cohort and case-control studies with NiV encephalitis fa-tality rate(CFR)and risk factors were selected.Results showed that a total of 25 literatures were included in the meta-analysis after retrieval and screening,and the fatality rate of NiV encephalitis was 64.6％(95％CI,60.8-68.2;I2=96.8％).Subgroup analysis showed that tree climbing(OR=1.43;95％CI:1.05-1.96),bats were seen near their nighttime residence(OR=2.38;95％CI:1.74-3.25)and direct contact with date palm SAP(OR=6.01;95％CI:4.07-8.89)Bananas(OR=2.25;95％CI:1.31-3.85)OR porcine(OR=11.87;95％CI:1.15-122.23)was significantly associated with NiV encephalitis.The results of this study suggest that NiV encephalitis has a high mortality rate,and tree climbing,nocturnal exposure to bats,and exposure to pig,banana,and date palm SAP increase the risk of NiV encephalitis.In order to prevent NiV transmission,epidemic surveillance,education and publicity should be strengthened and protective measures should be taken.
