As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

Financial incentives， as an intervention in behavioral therapy， have been proven to be beneficial in many health behaviors， such as drug addiction treatment， long-term antiviral therapy， and the prevention and treatment of chronic diseases. At present， typical financial incentive schemes mainly include commitment contracts and lottery-based models. Key factors in the design of such interventions include the adaptability of behavioral economic principles and medication behavior， the effectiveness and cost-effectiveness of design scheme， and the acceptability of intervention population. Although financial incentives have accumulated rich experience in health behavior interventions abroad， research on medication adherence remains limited， with existing intervention scheme design and mechanism constraints， and their effectiveness potentially varying across different cultural and social environments. China should explore practical models of financial incentives to enhance medication adherence, considering patients’ medication patterns and socio-cultural factors.

Objective:To investigate the correlation between plasma total α-synuclein (α-syn), phosphorylated α-synuclein (p-α-syn), neurofilament light chain(NfL) and subtypes of Parkinson disease(PD).Methods:A total of 62 PD patients admitted to the Department of Neurology, the Affiliated Huai 'an No. 1 People 's Hospital of Nanjing Medical University from September 2021 to January 2023 were selected and scored on the Hoehn-Yahr stage(H-Y), unified Parkinson's disease rating scale Ⅲ(UPDRS-Ⅲ), levodopa equivalent daily dosage(LEDD), mini-mental state examination(MMSE), Parkinson disease quality of life questionnaire(PDQ-39) and activities of daily living(ADL). During the same period, 25 healthy individuals matched in age and sex were enrolled as the control group (HC). Clinical characteristics and blood samples were collected. The plasma levels of α-syn, p-α-syn and NfL were detected by enzyme-linked immunosorbent assay(ELISA). PD patients were divided into tremor dominant type (TD, n=27) and akinetic-rigid dominant type (AR, n=35) based on UPDRS-Ⅲ scores. Multifactorial Logistic regression analysis was performed by SPSS 25.0 software to determine the influencing factors of subtypes of Parkinson disease. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off point of plasma NfL between the AR type and the TD type. Results:Plasma α-syn, p-α-syn, NfL levels in the PD group were significantly higher than those of the HC group ( Z=-2.537, -6.580, -7.101, all P<0.05). There were statistically significant differences between the AR type and the TD type in disease duration, H-Y stage, UPDRS-Ⅲ scores, LEDD and MMSE scores ( Z=-2.503, -3.021, -2.025, -2.086, -2.409, all P<0.05). While no significant difference was found in plasma α-syn and p-α-syn levels between the AR type and TD type ( Z=-0.341, -0.085, both P>0.05), the plasma NfL levels were notably higher in the AR type(92.79(16.84, 117.53) pg/mL) compared to the TD type (12.10(6.99, 100.17) pg/mL)( Z=-2.236, P<0.05). Plasma NfL levels were correlated with rigidity scores ( r=0.438, P<0.001), UPDRS-Ⅲ scores ( r=0.337, P<0.05) and motor subtypes ( r=0.286, P<0.05) in PD patients. Multivariate Logistic regression analysis showed that NfL was risk factor for AR( B=0.002, OR=1.002, 95% CI=1.001-1.003, P=0.017). The ROC curve analysis indicated that plasma NfL levels could predict different subtypes of PD with an AUC=0.667, optimal cutoff =26.527. Conclusion:There is a correlation between elevated plasma NfL levels and the occurrence of AR type of PD, suggesting that nerve injury is probably involved in the occurrence and progression of various motor subtypes of PD.

Objective:To compare the feasibility and efficacy of translocator protein (TSPO) molecular probes N, N-diethyl-2-(2-(4- 18F-fluorophenyl)-5, 7-dimethylpyrazolo[1, 5-a]pyrimidin-3-yl)acetamide ( 18F-FDPA) and 18F-(R)-( N-sec-butyl)-3-fluoromethyl- N-methyl-4-phenylquinoline-2-carboxamide (LW223) for the detection of abdominal vulnerable atherosclerotic plaques (VAP) in rabbit models. Methods:Nine healthy New Zealand white rabbits were divided into group A (control group, n=3), group B (VAP group, n=3) and group C (VAP treatment group, n=3) using completely randomized design. Animals were injected with 18F-FDPA and 18F-LW223 at the end of 12, 16 and 24 weeks. PET/CT and CT angiography (CTA) was performed 40-50 min post injection. All rabbits were sacrificed at the end of 24 weeks after imaging studies. All abdominal aortas were collected for pathological and immunofluorescence examination. Repeated measures analysis of variance (Bonferroni test) and paired t-test were used to analyze the data. Results:Target-to-background ratio (TBR; abdominal aortic lesion/left ventricular blood pool) values of 18F-FDPA in 3 groups at the end of 12, 16 and 24 weeks were significantly different ( F values: 68.09-144.88, all P<0.001). At the end of 12 weeks, there was no increased uptake of 18F-FDPA in the abdominal aorta region in 3 groups. The local 18F-FDPA uptake of the abdominal aorta in group B was significantly higher than the uptake in group C and that in group A at the end of 16 and 24 weeks( P<0.05 or P<0.001), and there were significant differences between group C and group A, with higher uptake in group C (both P<0.01). In 3 groups, there was no significant 18F-LW223 uptake in the abdominal aorta region at 3 time points of PET/CTA imaging. At the end of 12, 16 and 24 weeks, TBR values of 18F-FDPA and 18F-LW223 in 3 groups exhibited statistical differences ( t values: 2.88-36.79, all P<0.05). HE, immunofluorescent CD68 and TSPO staining showed more macrophage infiltration in group B than group C. Conclusion:18F-FDPA can be used to detect VAP in rabbits′ abdominal arteries at early time compared to 18F-LW223, and to evaluate the changes in the stability of vulnerable plaque after lipid-lowering drug intervention.

Objective:To investigate the correlation between plasma glial fibrillary acidic protein (GFAP), total α-synuclein (α-syn), phosphorylated α-synuclein (p-α-syn) and the disease progression in patients with Parkinson disease(PD).Methods:Sixty-three patients with PD including the outpatients and inpatients from Department of Neurology of Huai'an First People's Hospital were continuously collected as a PD group, and 25 healthy people matched in age and sex were selected as a healthy control (HC) group at the same time. The plasma levels of GFAP, α-syn, and p-α-syn levels in the PD group and HC group were detected by ELISA. SPSS 25.0 software was used for statistical analysis. Mann-Whitney U test was performed to assess the differences of GFAP, α-syn and p-α-syn levels between the two groups, and the correlation between GFAP and α-syn and p-α-syn levels in PD group was examined by Spearman correlation analysis. The levels of GFAP, α-syn and p-α-syn in different Hoehn-Yahr(H-Y) stages of PD group were compared by Mann-Whitney U test and Spearman correlation analysis. Results:The levels of GFAP (0.80(0.62, 0.97)ng/mL, 0.54(0.27, 0.88)ng/mL, Z=-3.216, P=0.001), α-syn (3.93(3.16, 6.02)ng/mL, 2.67(1.74, 4.47)ng/mL, Z=-2.600, P=0.009), and p-α-syn (5.80(1.31, 15.62), 0.71(0.61, 0.83), Z=-6.607, P<0.001) in PD group were higher than those in HC group, and the difference was statistically significant. In PD group, there was a significant positive correlation between GFAP and α-syn ( r=0.442, P<0.001) and p-α-syn ( r=0.493, P<0.001). GFAP in the advanced PD group was higher than that in the early PD group, and the difference was statistically significant( P=0.039). There was no significant difference in α-syn and p-α-syn between different H-Y stages of PD patients( P>0.05). Plasma GFAP was positively correlated with H-Y stages ( r=0.277, P=0.018). Conclusion:The level of plasma GFAP in PD patients is positively correlated with disease progression, which can be used as a potential biomarker for PD disease assessment.

Objective:To evaluate the efficacy of endoscopic stenting drainage for patients with malignant hilar biliary obstruction caused by unresectable hepatocellular carcinoma.Methods:Data of 106 patients with malignant hilar obstruction caused by unresectable hepatocellular carcinoma who received endoscopic stenting drainage in the Third Affiliated Hospital of Naval Medical University from January 2012 to January 2019 were retrospectively analyzed. According to the different stent types, they were divided into the metal stent group (30 cases) and the plastic stent group (76 cases). The observation indexes included clinical success rate, complication incidence, stent patency and overall survival time. The independent predictors for stent patency and overall survival of patients were analyzed by multivariate Cox regression model.Results:The overall clinical success rate was 67.9% (72/106) and the incidence of postoperative cholangitis was 29.2% (31/106). The clinical success rates were 93.3% (28/30) and 57.9% (44/76) ( χ2=12.40, P<0.001), and the incidences of postoperative cholangitis were 13.3% (4/30) and 35.5% (27/76) ( χ2=5.12, P=0.024) in the metal stent group and the plastic stent group, respectively. The median stent patency was 5.2 (95% CI:3.7-6.0) months, and the overall survival time was 3.0 (95% CI:2.5-3.7) months. Multivariate Cox regression analysis showed that hepatic drainage volume <30% was an independent predictor for stent patency ( HR=2.12, 95% CI:1.01-4.46, P=0.048). Bismuth type Ⅳ ( HR=2.06, 95% CI:1.12-3.77, P=0.020), Child-Pugh class C ( HR=4.09, 95% CI: 2.00-8.39, P<0.001) and plastic stent ( HR=1.87, 95% CI:1.21-2.90, P=0.005) were independent predictors for overall survival time. Conclusion:Hepatocellular carcinoma involving the hilar bile duct has a poor prognosis. Compared with plastic stents, metal stents show advantages in clinical success rate and incidence of postoperative cholangitis. Hepatic drainage volume <30% is an independent predictor for stent patency, and Bismuth type Ⅳ, Child-Pugh class C and plastic stent are independent predictors for overall survival time.

Objective:To study the past 10 years' experiences of neonatal hydrocephalus in a single-center.Methods:From January 2010 to December 2019, clinical data of infants with hydrocephalus admitted to Neonatology Department of our hospital were retrospectively analyzed. The infants were assigned into different groups according to gestational age, different etiologies and treatments. Their clinical characteristics and outcomes were compared.Results:A total of 223 infants with hydrocephalus were included. 136 (61.0%) infants were in the preterm group and 87 (39.0%) in the full-term group. The incidence of post-intracranial hemorrhage (ICH) hydrocephalus in preterm infants was significantly higher than full-term infants ( P<0.001). According to the etiologies, 58 infants (26.0%) had congenital hydrocephalus (congenital group), 82 cases (36.8%) developed post-ICH hydrocephalus (ICH group), 48 cases (21.5%) had post-CNS-infection hydrocephalus (infection group) and 35 cases (15.7%) had post-ICH+CNS-infection hydrocephalus (ICH+infection group). The incidences of perinatal asphyxia, neonatal resuscitation and endotracheal intubation within 3 d after birth in the ICH group were significantly higher than the other groups ( P<0.05). Among the four groups, the infection group had the highest incidence of neonatal sepsis, the congenital group had the highest incidence of patent ductus arteriosus and the ICH group had the highest incidence of respiratory diseases (all P<0.05).137 cases (61.4%) received non-surgical therapy, 48 cases (21.5%) had temporary drainage, 37 cases (16.6%) with permanent shunt and 1 case (0.4%) intracranial hematoma removal. The congenital group and ICH group with permanent shunt showed significantly higher rate of improvement than temporary drainage group and non-surgical group ( P<0.001). Conclusions:The main etiologies of neonatal hydrocephalus are ICH and CNS infection. The incidence of post-ICH hydrocephalus in premature infants was quite high. Hydrocephalus of different etiologies have different comorbidities. Maternal and infant care during pregnancy and delivery, prevention of neonatal sepsis and ICH are crucial in the prevention of hydrocephalus. More studies are needed for better treatment.
