Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons and the accumulation of Lewy bodies, leading to motor and nonmotor symptoms. While both genetic and environmental factors contribute to PD, recent studies highlight the crucial role of lipid metabolism disturbances in disease progression. Altered lipid homeostasis promotes protein aggregation and oxidative stress, with significant changes in lipid classes such as sphingolipids and glycerolipids observed in patients with PD. These disturbances are involved in key pathological processes, such as α-synuclein aggregation, organelle dysfunction, lipid-mediated neuroinflammation, and impaired lipid homeostasis. This review examines the relationship between lipid species and PD progression, focusing on the physiological roles of lipids in the central nervous system. It explores the mechanistic links between lipid metabolism and PD pathology, along with lipid-related genetic risk factors. Furthermore, this review discusses lipid-targeting therapeutic strategies to mitigate PD progression, emphasizing the potential of lipid modulation for effective treatment development.

Objective:In order to reduce the trauma associated with fetal cardiopulmonary bypass(F-CPB), Our team plans to develop a minimally invasive F-CPB through a small incision in the right axilla. The efficacy of this technique will be verified by using a big experimental animal model, thereby laying the foundation for fetal cardiac surgery supported by F-CPB in the future.Methods:Ten pregnant sheep were divided into F-CPB group(n=5) and control group(n=5). After fasting for 24 h, fetal lambs in the F-CPB group underwent a right axillary incision to establish F-CPB running for 1 h; The control group of fetal lambs only expose heart 1 h without F-CPB. Collect blood sample for laboratory test at the CPB vehicle before(T0), 30 min(T1), and 1 h after F-CPB running(T2) for the F-CPB group and through Superior Vena Cava before(T0), 30 min(T1), and 1 h after F-CPB running(T2) for the control group.Results:The blood routine indicators such as RBC, HCT, and Hb in the F-CPB group of fetal lambs decreased significantly during F-CPB, and their distribution showed significant statistical differences compared with the control group( P<0.05). There were no significant statistical differences in blood gas indicators such as pH, PO 2, PCO 2, and lactate concentration between the F-CPB group and the control group( P>0.05). There was no statistically significant difference in the concentration of cTnI in fetal lamb serum at each time point( P>0.05). There were significant statistical differences( P<0.05) in the distribution of fetal lamb Alb, γ-GGT, CK concentration and cholesterol concentration at various time points in the F-CPB group compared with the control group in liver function examination. In addition, the distribution of BUN in fetal lambs showed a significant difference between the two groups( P=0.006). Conclusion:A minimally invasive F-CPB via small incision in the right axilla is safe and feasible. The experimental animal model has demonstrated that this technique has minimal impact on the vital organ functions and internal environment of fetal lambs, thereby laying the foundation for clinical fetal cardiac surgery in the future.

Objective To find the sensitive parameters for evaluating the cerebral CT perfusion changes in patients before and after carotid endarterectomy(CEA).Methods Between November 2015 and April 2017,the data of 27 patients who underwent CEA and conducted CT perfusion(CTP) examination before and after the operation were analyzed retrospectively.The different perfusion parameters of the cerebral hemisphere in different areas were analyzed before and after the operation.Absolute perfusion parameters include:cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time (MTT) and time to peak(TTP);relative perfusion parameters include:rCBV,rCBF,rMTT and rTTP;relative to brainstem perfusion parameters include:sCBV, sCBF, sMTT and sTTP.Paired sample t test (normal distribution of quantitative data) was used to analyze the parameters differences before and after the operation.Results The postoperative perfusion parameters of the operated side cerebral hemisphere compared with the preoperative:(1)The absolute perfusion parameters:the decreased of TTP in frontal lobe,anterior watershed region,middle cerebral artery territory and basal ganglia region[preoperative(22.4 ± 3.0)s,(23.0 ± 3.1)s, (23.2±2.2)s,(21.9±2.7)s,postoperative(20.1±2.4)s,(20.5±2.7)s,(20.7±2.8)s,(19.5±2.8)s]had statistical significance(t values were 2.437, 2.504, 2.882, 2.431, P<0.05).(2)The relative perfusion parameters:the decreased of rMTT in middle cerebral artery territory and basal ganglia region(preoperative 1.18±0.44,1.06± 0.22,postoperative 1.04±0.33,0.97±0.16)and the decreased of rTTP in middle cerebral artery territory and basal ganglia region(preoperative 1.07±0.15,1.04±0.05,postoperative 1.00±0.13,0.97±0.06)had statistical significance(t values were 2.235, 2.244, 2.245, 2.268, P<0.05).(3)The relative to brainstem perfusion parameters:the decreased of sCBV in middle cerebral artery territory(preoperative 1.08±0.16,postoperative 0.98 ± 0.15), the increased of sCBF in frontal lobe and middle cerebral artery territory(preoperative 1.07 ± 0.19, 1.00 ± 0.21,postoperative 1.17 ± 0.21, 1.09 ± 0.20),the decreased of sMTT in middle cerebral artery territory and basal ganglia region(preoperative 1.27±0.29,0.94±0.11,postoperative 1.05±0.05,0.86±0.10), the decreased sTTP in frontal lobe,anterior watershed region,middle cerebral artery territory and basal ganglia region(preoperative 1.05±0.05,1.07±0.06,1.10±0.08,1.02±0.03,postoperative 0.97±0.05,0.96± 0.06,0.98±0.07,0.95±0.01)had statistical significance(t values were 2.882,-2.995,-2.737,2.172,2.425, 2.249, 2.263, 2.806, 3.267, P<0.05). Conclusion CTP is significant to evaluate the changes of cerebral perfusion in patients who underwent CEA. The relative to brainstem parameters are more valuable than relative parameters and absolute parameters in judging the perfusion changes after CEA.

Objective To investigate the patency rate and restenosis after percutaneous transluminal angioplasty (PTA) for the treatment of arteriovenous fistula (AVF) and arteriovenous graft (AVG) stenosis in dialysis patients. Methods The patients who were successfully treated by PTA for the first time in the blood purification center of the 2nd Affiliated Hospital of Nanjing Medical University from January 2016 to June 2017, including 71 cases of AVF in the forearm, 52 cases of AVF in the upper arm and 59 cases of AVG were recorded. The data of different stenosis parts were analyzed before and after treatment and followed up for 12 months. The initial patency rate and assisted-PTA patency rate were observed at 3 months, 6 months, 9 months, and 12 months after ultrasound interventional therapy, and the initial patency time for patients who needed to reintervention among all types of pathways were recorded. Results The initial patency rates at 3 months, 6 months, 9 months and 12 months after ultrasound interventional therapy were 98.59%, 90.14%, 71.93%, 54.93% respectively in forearm AVF, 90.38%, 65.38%, 42.31%, 32.69% respectively in upper arm AVF, 91.53%, 32.20%, 6.78%, 1.69% respectively in AVG, and the PTA-assisted patency rates were 98.59%, 97.18%, 95.77%, 94.37% respectively in forearm AVF, 92.31%, 86.54%, 84.62%, 80.77%respectively in upper arm AVF, 100.00%, 98.31%, 96.61%, 93.22% respectively in AVG, while the initial patency time was (8.99 ± 3.54) months in forearm AVF, (6.33 ± 3.01) months in upper arm AVF, (4.80 ± 1.40) months in AVG respectively. Conclusions Ultrasound can comprehensively evaluate the function of peripheral vascular access, guide PTA treatment, and evaluate treatment outcomes. Ultrasound intervention therapy has best initial patency rate for forearm AVF stenosis. The prognosis of upper arm AVF stenosis PTA is relatively poor due to the easy cephalic stenosis. Although AVG has a short interval of restenosis, it can achieve a better long-term patency rate through regular intervention with ultrasound intervention.
