Objective:To investigate the differences of the glymphatic system (GS) function between patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) and healthy controls and between different seizure types by using diffusion tensor imaging along perivascular space (DTI-ALPS), and to analyze the correlation between GS function and the course of disease, as well as the efficacy of predicting the surgical outcome.Methods:This study was a cross-sectional study. A total of 171 patients with mTLE-HS (mTLE-HS group) and 75 healthy volunteers (HC group) were retrospectively enrolled from July 2009 to July 2021 at Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University. The general information of all subjects, such as seizure type (partial seizure, secondary generalized seizure), surgical outcome, etc., was analyzed. The 3D magnetization prepared rapid gradient echo T 1WI and DTI sequence images were collected. The VBM analysis method was used to segment cerebrospinal fluid and calculate the volume. The ALPS index of the bilateral brain was calculated using the Atlas-based DTI-ALPS method. Independent sample t-test or paired t test were used to compare the ALPS index between the mTLE-HS group and HC group, and between patients with different seizure types. Pearson correlation analysis was used to analyze the correlation between bilateral ALPS index and disease duration in mTLE-HS group. The predictive value of the ALPS index for surgical outcomes was evaluated by receiver operating characteristics curve and area under the curve. Results:Among the 171 mTLE-HS patients, 98 patients were mTLE with left-side HS (mTLE-LHS) and 73 patients were mTLE with right-side HS (mTLE-RHS); 37 patients underwent surgical treatment, including 27 with good prognosis and 10 with poor prognosis. Compared with the HC group, the left-side ALPS index of mTLE-LHS and mTLE-RHS were both decreased ( P<0.05). The right-side ALPS index in mTLE-RHS was lower than that in the HC group ( P<0.001). There was no significant difference in the right-side ALPS index between mTLE-LHS and HC group ( P=0.080). The ALPS index on the affected side of patients with secondary generalized seizures was significantly lower than that of patients with only partial seizures (all P<0.05), but the difference in ALPS index on the healthy side was not statistically significant( P>0.05). The left-side and right-side ALPS index in mTLE-LHS were negatively correlated with disease duration ( r=-0.272, P=0.007; r=-0.307, P=0.002), but no significant correlation was found between the left-side or right-side ALPS index in mTLE-RHS (all P>0.05). The DTI-ALPS index on the affected side in mTLE-HS patients exhibited good diagnostic accuracy for surgical outcome classification, with an area under the curve of 0.778. Conclusions:The patients with mTLE-HS exhibit dysfunction of the GS, and the degree of impairment is related to the type of seizure and the course of epilepsy. The ALPS index, which characterizes the function of GS, demonstrates good diagnostic accuracy for classifying surgical outcomes.

Objective:To investigate the short-term clinical efficacy of two fixation methods, mini-titanium plate fixation and suture suspension, in cervical posterior unilateral laminoplasty, and to explore the relationship between changes in the cervical sagittal sequence and therapeutic outcomes.Methods:A retrospective analysis was conducted on 55 patients who underwent cervical posterior unilateral laminoplasty with mini-titanium plate fixation and 50 patients with suture suspension at the First People's Hospital of Lianyungang from September 2020 to January 2023. All patients were followed up for 12 months, and the axial symptoms was recorded. The main clinical efficacy evaluations included before surgery and 12 months after surgery visual analog score (VAS) for neck pain, Japanese Orthopaedic Association score (JOA) and neck disability index (NDI). Four parameters were recorded before surgery and 12 months after surgery to assess the sagittal sequence: C 2-7 sagittal vertical axis (C 2-7SVA), T 1 slope angle (T 1s), C 2-7Cobb angle and cervical range of motion. Results:The mini-titanium plate fixation group had 5 cases of axial symptoms, while the traditional suture suspension group had 16 cases; the postoperative VAS, JOA and C 2-7Cobb angle in the mini-titanium plate fixation group were all less than those in the suture suspension group, with statistically significant differences ( P<0.05). Specifically, the postoperative VAS in the mini-titanium plate fixation group was (1.93 ± 1.42) points, and (2.67 ± 2.15) points in the suture suspension group ( P = 0.049); the JOA was (10.39 ± 2.20) points in the mini-titanium plate fixation group and (9.62 ± 1.52) points in the suture suspension group ( P = 0.012); the C 2-7Cobb angle was (21.087 ± 3.564)° in the mini-titanium plate fixation group and (23.092 ± 1.265)° in the suture suspension group ( P = 0.003). There was no statistical difference in operation time and blood loss between two groups ( P>0.05). The postoperative C 2-7SVA, T 1s and range of motion in the traditional suture suspension group were less than those in the mini-titanium plate fixation group, with statistically significant differences ( P<0.05). Specifically, the postoperative C 2-7SVA was (25.700 ± 3.035) mm in the mini-titanium plate fixation group and (23.946 ± 3.079) mm in the suture suspension group ( P = 0.004); the postoperative T 1s was (28.770 ± 2.361)° in the mini-titanium plate fixation group and (26.746 ± 3.198)° in the suture suspension group ( P = 0.004); the postoperative range of motion was (32.651 ± 4.995)° in the mini-titanium plate fixation group and (28.672 ± 5.874)° in the suture suspension group ( P = 0.003). Conclusions:Cervical posterior unilateral laminoplasty with mini-titanium plate fixation can effectively improve VAS, JOA, and restore neurological function, maintaining the cervical spine's sagittal balance, stability, and maximum range of motion.

Objective To evaluate the value of perfusion imaging mismatch and low perfusion ratio(HIR)based on CT perfusion imaging in predicting acute intracranial large vessel occlusion(LVO)associated with intracranial atherosclerotic stenosis(ICAS).Methods A total of 82 pa-tients with acute intracranial LVO who underwent emergency thrombectomy in our hospital from February 2019 to December 2020 were enrolled in this study.According to the etiology,they were divided into ICAS-related LVO group(ICAS-LVO,65 cases)and cardiogenic embolism group(17 cases).ROC curve was plotted to analyze the predictive value of CT perfusion imaging parame-ters.Results Compared with the cardiogenic embolism group,the ICAS-LVO group had signifi-cantly larger male ratio,higher BMI and TG level,more severe progression of disease,longer time from onset to surgery,larger proportion of ischemic penumbra and higher mismatch ratio,and ob-viously less ratio of atrial fibrillation,lower BNP and HDL levels,smaller infarct volume,and lower HIR(P＜0.05,P＜0.01).ROC curve analysis showed that HIR and mismatch ratio had good predictive value for the etiology of ICAS-LVO.The optimal cut-off value of HIR was 0.26,with an AUC value of 0.74,a specificity of 0.88,and a sensitivity of 0.54.The optimal cutoff for the mismatch ratio was 3.84,with an AUC value of 0.84,a specificity of 0.75,and a sensitivity of 0.90.Generalized linear model revealed that HIR and cerebral blood volume index had no signifi-cant difference in prognostic performance(P=0.175).Conclusion HIR and mismatch ratio are helpful to identify the pathogenesis earlier and formulate surgical strategies more accurately,thereby reducing iatrogenic injury to a greater extent,increasing the effective reperfusion rate,re-ducing the disability and mortality,and improving the prognosis of clinical outcomes.

Objective:To measure and assess relevant radiation doses at the radiotherapy site of the first domestic single-vault proton therapy system.Methods:The radiation levels of the therapy system during and after beam irradiation were measured, and annual effective doses were assessed for personnel at the site.Results:During beam irradiation, the highest radiation dose was detected at the shielded door of the equipment floor, with a gamma radiation level of 2.140 μSv/h and a neutron radiation level of 0.850 μSv/h. Neutron radiation disappeared immediately once the beams stopped. In contrast, the radiation activated originated mostly from gamma rays. A longer time after beams stopped was associated with lower induced radiation intensity at the same location. Furthermore, a farther distance from the irradiated object corresponded to lower induced radiation intensity at the same time. The assessment result reveal that the annual effective doses to the personnel were at the safe level, with physicists exposed to the highest dose of 2.138 mSv.Conclusions:The radiation level at the studied proton therapy site meets the safety requirement, and the treatment can be performed safely at this site.

Objective:To establish an in vivo infection model of West Nile virus (WNV) pseudovirus and evaluate the neutralizing activity of antibody WNV-XH1.Methods:A stable cell line that can package the WNV pseudovirus was established in the early stage to prepare the pseudovirus supernatant. The supernatant was concentrated and infected BHK21 cells to detect the titer of the pseudovirus. After intraperitoneal injection of the pseudovirus into C57BL/J mice, bioluminescence imaging was performed to observe the infection status of the pseudovirus in the mice. After simultaneous infection, blood was collected and ELISA was used to detect NS1 levels in mouse serum. The in vivo functional activity of antibody WNV-XH1 was evaluated using the established mouse infection model.Results:Fluorescence was detected in C57BL/J mice infected with WNV pseudovirus, and the NS1 levels in the peripheral blood serum of mice infected with pseudovirus were significantly higher than those of non infected mice (1.453±0.09vs0.305±0.018). After intravenous administration of WNV-XH1 antibody before the attack, the fluorescence signal in the mice decreased and the serum NS1 level decreased (0.384±0.015).Conclusions:A successful in vivo infection model of WNV pseudovirus was established, and it was confirmed that the antibody WNV-XH1 had a protective effect against WNV pseudovirus infection in vivo.

Objective To establish a noninvasive diagnostic model for liver fibrosis in chronic hepatitis B(CHB)patients with normal alanine aminotransferase(ALT)and an age of≤30 years by selecting specific indicators from the commonly used noninvasive indicators such as clinical,biochemical,and imaging indicators,to avoid invasive liver biopsy in such patients to some extent,and to guide the timing of antiviral therapy.Methods A total of 251 CHB patients with normal ALT and an age of≤30 years who underwent liver biopsy in Shenzhen Third People's Hospital and The First Hospital of Changsha from January 2019 to January 2022 were enrolled,with 175 patients in the model group and 76 patients in the validation group,and commonly used clinical indicators were obtained based on clinical experience and related articles.The two-independent-samples t test or the two-independent-samples Mann-Whitney U rank sum test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.A Spearman rank correlation analysis was used to investigate the correlation between each indicator and liver fibrosis and identify the indicators with correlation(P<0.01,r>0.200);a Logistic regression analysis was used to establish a noninvasive diagnostic model,and the receiver operating characteristic(ROC)curve was used to evaluate its performance and perform validation of the model;this model was then compared with the widely used models of aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4(FIB-4).The Kappa consistency test was used to investigate the consistency of pathological results.Results A total of 17 commonly used clinical indicators were obtained,among which 9 indicators(ALT,aspartate aminotransferase[AST],gamma-glutamyl transpeptidase[GGT],ferritin[FERR],platelet count[PLT],procollagen type Ⅲ amino-terminal peptide[PⅢP],collagen Ⅳ[CⅣ],HBV DNA,and spleen thickness)were correlated with liver fibrosis(P<0.01,r>0.232).Based on the above indicators,the predictive model was established as P=1/(1+e-γ),γ=-1.902+0.106×AST-0.011×PLT-0.265×HBV DNA+0.059×PⅢP,in which P was the probability for predicting≥S2 liver fibrosis and γ was the predictive index.The comparison between each indicator and the model showed that the model had the largest area under the ROC curve of 0.852,with a sensitivity of 92.7%and a specificity of 76.9%.The model was validated in 76 patients and showed an accuracy of 77.600%.The model was compared with APRI and FIB-4,and the results showed that the model has good accuracy.Conclusion Compared with the models of APRI and FIB-4 commonly used in the world,this model can more accurately judge the degree of liver fibrosis in such patients,thereby replacing liver biopsy to some extent and guiding the timing of antiviral therapy.

Objective:To evaluate the relationship between microRNA-29a (miR-29a) and p53 up-regulated modulator of apoptosis (PUMA) in propofol-induced reduction of glucose deprivation (GD)-induced injury to human glioma cells.Methods:Human glioma U87 cells were cultured in vitro to the logarithmic growth phase. Cells were then divided into 6 groups ( n=24 each) by the random number table method: control group (group C), group GD, propofol + GD group (group P+ GD), miR-29a inhibitor group (group I), miR-29a inhibitor + GD group (group I+ GD) and miR-29a inhibitor+ propofol+ GD group (group I+ P+ GD). Cells were cultured in normal condition in group C. The culture medium was changed to glucose-free DMEM solution, and the cells were cultured for 12 h in group GD. In group P+ GD, cells were incubated with propofol 10 μmol/L for 12 h and then incubated in glucose-free DMEM solution for 12 h. In group I, group I+ GD and group I+ P+ GD, miR-29a inhibitor was transfected into cells using lipofectamine transfection kit, and then the cells were cultured for 48 h, and the other treatments were similar to those previously described in group P+ GD. The cell survival rate, mitochondrial membrane potential and level of reactive oxygen species (ROS) were determined. The expression of miR-29a was detected by quantitative real-time polymerase chain reaction, and the expression PUMA was detected by Western blot. Results:Compared with group C, the cell survival rate and mitochondrial membrane potential were significantly decreased, the level of ROS was increased, the expression of miR-29a was down-regulated, and the expression of PUMA was up-regulated in group GD and group I ( P<0.05). Compared with group GD, the cell survival rate and mitochondrial membrane potential were significantly increased, the level of ROS was decreased, the expression of miR-29a was up-regulated, and the expression of PUMA was down-regulated in group P+ GD, and the cell survival rate and mitochondrial membrane potential were significantly decreased, the level of ROS was increased, the expression of miR-29a was down-regulated, and the expression of PUMA was up-regulated in group I+ GD ( P<0.05). Compared with group P+ GD, the cell survival rate and mitochondrial membrane potential were significantly decreased, the level of ROS was increased, the expression of miR-29a was down-regulated, and the expression of PUMA was up-regulated in group I+ P+ GD ( P<0.05). Conclusions:The mechanism by which propofol reduces glucose deprivation-induced injury to human glioma cells is related to up-regulation of miR-29a expression and down-regulation of PUMA expression.
