Objective To explore the application value of simple drawing line puncture combined with visual articular process arthroplasty in lateral foraminoscopy.Methods A retrospective analysis was performed on 89 patients with single-segment lumbar disc herniation treated with lateral foraminoscopy from May 2019 to December 2022,including traditional transforaminal endoscopic spine system(TESSYS)technology(conventional group,35 cases)and simple drawing line puncture combined with visual articular process arthroplasty(modified group,54 cases).The fluoroscopy times,puncture time,and operation time of the two groups were compared.The Visual Analogue Score(VAS),Oswestry Disability Index(ODI),and MacNab criteria were used to evaluate the surgical effect at 3 d after surgery and at the last follow-up.Results All the operations were successfully completed without conversion to open surgery.In the conventional group,there was 1 case of L4 nerve root injury,who was considered intraoperative nerve root compression injury.There was no abnormality in lower limb muscle strength after surgery,but hyperalgesia and numbness in the innervated cutaneous area accompanied by nocturnal cramps.The patient was given treatment with pregabalin,mecobalamin,vitamin B1 and B6 for 2 months,and returned to normal at 1 year of follow-up.The other cases had no complications such as dural injury,abdominal organ injury,or incision infection.Recurrence occurred in 1 case in the conventional group and 2 cases in the modified group,and all the 3 cases occurred within 3 months after operation.Among them,2 patients had severe symptoms and underwent endoscopic revision again,and the other patient improved after conservative treatment.Compared with the conventional group,the puncture times[(1.8±0.7)times vs.(7.5±1.1)times,t=27.543,P=0.000].fluoroscopy times[(5.7±1.8)times vs.(23.2±2.2)times,t=41.235,P=0.000]and operation time[(72.7±7.2)min vs.(92.7±7.7)min,t=12.317,P=0.000]in the modified group were significantly reduced or shortened,and there was no significant difference in postoperative hospital stay[(3.2±0.6)d vs.(3.3±0.6)d,t=0.062,P=0.951]between the two groups.The conventional group was followed up for(14.0±1.3)months and the modified group was followed up for(13.6±1.2)months.There were no significant differences in VAS scores[(1.5±0.6)points vs.(1.6±0.7)points,t=0.751,P=0.455].ODI[(10.8±3.4)％vs.(11.8±3.9)％,t=1.284,P=0.202].and excellent and good rate of MacNab criteria[100％(54/54)vs.100％(35/35),Z=-0.981,P=0.327]between the two groups at the last follow-up.Conclusions Simple drawing line puncture combined with visual articular process arthroplasty can significantly improve the accuracy of intervertebral foramen aspiration,with simple operation,reduced X-ray exposure for doctors and patients,shortened operation time,and improved surgical safety.It is worthy of promotion and application in percutaneous foraminoscopy.

Objective:To investigate the potential value of cerebral glucose metabolism characteristics in anti-leucine-rich glioma-inactivated protein 1 (LGI1) antibody-related encephalitic patients during acute phase as the clinical indicator of disease outcomes.Methods:From October 2019 to December 2023, 28 patients (18 males, 10 females; age (56.6±11.9) year) with anti-LGI1 antibody-related encephalitis diagnosed at Huashan Hospital, Fudan University were prospectively enrolled. All patients received baseline brain 18F-FDG PET imaging and were divided into different subgroups according to the prognosis (good prognosis and poor prognosis groups) and recurrence (recurrence and non-recurrence groups) after follow-up. The difference of Montreal Cognitive Assessment (MoCA) score between the two groups was compared by Mann-Whitney U test. Statistical parametric mapping (SPM) analysis was used to analyze the PET images of different groups by independent-sample t test, and the characteristics of cerebral glucose metabolism of patients with different outcomes were obtained. Results:MoCA scores between the recurrence group ( n=6) and the non-recurrence group ( n=22; 14.0(9.8, 20.5) vs 22.0(18.0, 24.0); Z=2.17, P=0.030), and between the poor prognosis group ( n=13) and the good prognosis group ( n=15; 14.0(10.0, 22.0) vs 22.0(19.8, 25.3); Z=2.47, P=0.013) were significantly different. Compared with the good prognosis group, the cerebral glucose metabolism in the poor prognosis group was decreased in the bilateral frontal lobe, lateral temporal lobe, inferior parietal lobule and cingulate gyrus, but increased in the brainstem, bilateral lentiform nucleus and bilateral paracentral lobule/postcentral gyrus (all t=1.71, all P<0.05). Compared with the non-recurrence group, the metabolism of bilateral medial frontal gyrus, anterior cingulate gyrus, bilateral insula, superior temporal gyrus and thalamus decreased in the recurrence group, while the metabolism of bilateral precentral gyrus, inferior frontal gyrus and bilateral lentiform nucleus increased (all t=1.71, all P<0.05). Conclusion:18F-FDG PET imaging reveals the differences in brain metabolism of anti-LGI1 antibody-related encephalitic patients at baseline with different outcomes (prognosis, recurrence or not), which can provide a new perspective for the clinical evaluation of the disease at baseline.

Smart healthcare plays an important role in easing the strain on medical resources and improving the continuity of chronic disease management. This study analysed the iatrogenic risks from the intrinsic attributes and the external environment of smart healthcare, including doctor-patient conflict risk, technical operation risk, information leakage risk, humanistic absence risk, legal risk, regulatory risk and ethical risk. Based on the " structure process result" model, suggestions were proposed to optimize the construction of a smart healthcare platform for chronic diseases, improve the legal system and industry standards, strengthen talent cultivation and capacity building, establish an integrated regulatory system, and regularly evaluate the effectiveness of chronic disease management. These suggestions provided references for creating a healthy, orderly, and safe smart healthcare environment for chronic disease patients.

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.

As the "main force" for providing health services, there has been a constant increase in the number of health service and management graduates in recent years, but with a lack of satisfactory quality. The concept of outcome-based education (OBE) takes the needs of all parties as the starting point and foothold for practice, which can ensure the consistency between the goal of talent training and the learning achievements of students to the greatest extent. This article proposes to integrate the educational concept of OBE into the training path of health service and management talents, clarify talent training objectives by understanding the needs of all parties, optimize the curriculum system according to training objectives, and construct a diversified evaluation system with the organic combination of process evaluation and summative assessment, in order to continuously optimize the training path of health service and management talents and cultivate applied health management talents with knowledge, ability, and quality.
