ObjectiveTo investigate the anti-Alzheimer's disease （AD） effect of Dipsacus asper（DA） in the Caenorhabditis elegans model， and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α （PPARα）/transcription factor EB （TFEB） pathway. MethodsFirst， transgenic AD C. elegans individuals were assigned into the blank control， model， positive control （WY14643， 20 µmol·L^-1）， and low-， medium-， and high-dose （100， 200， and 400 mg·L^-1， respectively） DA groups. The amyloid β-42 （Aβ₄₂） formation in the muscle cells， the paralysis time， and the deposition of amyloid β-protein （Aβ） in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ， LC3I， LAMP2， and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα， and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB， Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain （LBD）. ResultsCompared with the model group， the positive control group and 200 and 400 mg·L^-1 DA groups showed prolonged paralysis time （P<0.05）， and all the treatment groups showed decreased Aβ deposition in the head （P<0.01）. DA within the concentration range of 50-500 mg·L^-1 did not affect the viability of BV2 cells. In addition， DA enhanced the autophagy flux （P<0.05）， up-regulated the mRNA levels of beclin1， Atg5， LAMP2， and CLN2 （P<0.05， P<0.01）， promoted the nuclear translocation of TFEB （P<0.05）， increased LAMP2 expression and autophagy flux （P<0.05， P<0.01）， and enhanced the transcriptional activities of PPARα and TFEB （P<0.01）. The positive control group and 200 and 400 mg·L^-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus （P<0.01）. UPLC-MS detected nine known compounds of DA， from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

Objective To analyze the operation of Measles Surveillance System (MSS) in Hebei Province, and to provide evidence for measles elimination. Methods Measles surveillance data was collected from the MSS from 2020 to 2023, and a modified weighted technology for order preference by similarity to an ideal solution (TOPSIS) method was used to evaluate the surveillance indexes of measles in Hebei Province. Results The operation quality of the measles surveillance system in Hebei Province was improved year by year, with the highest quality in 2023, and all the indicators reached the monitoring program standards. The quality of measles surveillance system was not balanced among cities, and the main influencing factor was the substandard sensitivity indicators. The quality of measles surveillance system was the highest in Baoding City and the lowest in Zhangjiakou City. Conclusion The measles surveillance system in Hebei province is running well, and the sensitivity of the surveillance system should be improved to keep the high-quality operation of the surveillance system.

Objective To analyze the occurrence characteristics of adverse events following immunization (AEFI) of 23-valent pneumococcal polysaccharide vaccine (PPSV-23) in Hebei Province and to evaluate the safety of the vaccine. Methods AEFI cases related to vaccination of PPSV-23 in Hebei Province from January 1, 2020 to December 31, 2022 were collected through the AEFI surveillance module of Chinese Center for Disease Control and Prevention Information System. The incidence of reported AEFI cases were then analyzed and compared. Results The reported incidence rate of AEFI of PPSV-23 was 56.12 /100,000 doses, and the incidence rate of adverse reactions was 55.50 /100 000 doses. The incidence rate of common adverse reactions was 53.94/100 000 doses, and the incidence rate of rare adverse reactions was 1.56/100 000 doses. Most of the reported AEFI cases caused by PPSV-23 were common adverse reactions, which occurred mainly within one day after vaccination, and the overall regression was positive. Conclusion The 23-valent pneumococcal polysaccharide vaccine used in Hebei Province is safe，but its safety monitoring still needs to be strengthened.

Objective To explore the interventional effect of repetitive transcranial magnetic stimulation (rTMS) on tardive dyskinesia (TD) in schizophrenic patients. Methods A total of 105 schizophrenic patients were selected as subjects and randomly divided into 1 Hz treatment group, 10 Hz treatment group and control group, with 35 patients in each group. All three groups received rTMS treatment for 12 weeks. The Abnormal Involuntary Movement Scale (AIMS), Scale for the Assessment of Negative Symptoms (SANS), Positive and Negative Syndrome Scale (PANSS) and Treatment Emergent Symptom Scale (TESS) scores were compared among the three groups. Physiological indicators such as electrocardiogram, blood routine, blood biochemistry and hormone levels were monitored. Results After treatment, the total AIMS scores in the 1 Hz and 10 Hz treatment groups were significantly lower than before treatment, and those in the 1 Hz and 10 Hz treatment groups were significantly lower than those in the control group (P < 0.05). The reduction rates of AIMS scores in the 1 Hz and 10 Hz treatment groups were 68.6% and 65.7%, respectively, which were significantly higher than the 22.9% in the control group (P < 0.05). After treatment, the total SANS and PANSS scores in the 1 Hz and 10 Hz treatment groups were significantly lower than before treatment, and those in the 1 Hz and 10 Hz treatment groups were significantly lower than those in the control group (P < 0.05). There was no statistically significant difference in the total AIMS score, efficacy and total PANSS score between the 1 Hz and 10 Hz treatment groups (P>0.05). There were no significant differences in the total TESS scores and physiological indicators among the three groups before and after treatment (P>0.05). Conclusion Both 1 Hz and 10 Hz rTMS can effectively improve TD in schizophrenic patients with good safety and have no significant side effects or physiological damage.

Gastric cancer(GC)is one of the most common and high mortality tumors in the world,and the clinical staging during diagnosis is closely related to the prognosis of patients.Therefore,finding sensitive diagnostic biomarkers to improve the early diagnosis rate has become an urgent issue.Exosomes are nanoscale extracellular vesicles secreted by various cells,which play an important role in cellular communication by transporting bioactive substances in tumor microenvironment(TME).CircRNA is a type of non-coding RNA with a specific structure.Because it is difficulty in degradation,it can be enriched in extracellular vesicles and participate in various pathophysiological processes mediated by it.Exo-circRNA can affect the proliferation,invasion,drug resistance and tissue metastasis of tumor cells,and has more significant diagnostic specificity than conventional diagnostic biomarkers in clinical practice.It may become a supplement to biomarker for the diagnosis and prognosis of GC.This article briefly introduces the characteristics,formation mechanism and role of extracellular vesicles and circRNA in GC.It discusses in detail the role of exo-circRNA in the occurrence and development of GC,and discusses their potential clinical application value and challenges in GC.

Objective To investigate the relationships of the expression of serum matrix metalloproteinase-9 (MMP-9), soluble urokinase type plasmin activator receptor (suPAR) and plasmin activator inhibitor-1 (PAI-1) with the cardiac function grading and prognosis in elderly patients with chronic heart failure (CHF). Methods A total of 108 CHF patients and 50 healthy individuals with physical examination in the same period in Langfang City Hospital of Traditional Chinese Medicine were respectively selected as study group and control group. The blood samples were collected for detection of serum levels of MMP-9, suPAR and PAI-1. The differences in serum indicators among patients with different cardiac functional grades of the New York Heart Association (NYHA) and different prognoses were compared, and the predictive values of serum indicators for poor prognosis were analyzed as well. Results Compared with the control group, the serum levels of MMP-9, suPAR and PAI-1 in the study group were significantly higher (P < 0.05). The levels of serum MMP-9, suPARand PAI-1 increased gradually and significantly in patients with the increase of NYHA grading as grade Ⅱ, grade Ⅲ and grade Ⅳ (P < 0.05). The results of the one-year follow-up showed that there were 65 cases with good prognosis and 43 cases with poor prognosis, and the poor prognosis rate was 39.81% (43/108). Compared with patients of good prognosis, patients with poor prognosis had higher age, higher incidence of complicated hypertension, lower left ventricular ejection fraction (LVEF), and higher levels of left ventricular end diastolic diameter (LVEDD), MMP-9, suPAR and PAI-1 (P < 0.05). Logistic regression analysis showed that age, MMP-9, suPAR and PAI-1 were the risk factors for poor prognosis in elderly patients with CHF, while LVEF was a protective factor for poor prognosis in elderly patients with CHF (P < 0.05). The area under the curve (AUC) of serum MMP-9, suPAR and PAI-1 detected separately and in combination were 0.711, 0.829, 0.768 and 0.840 respectively, the sensitivity and specificity of the three indexes in combination were 88.21% and 79.46% respectively. Conclusion The expression levels of serum MMP-9, suPAR and PAI-1 in elderly patients with CHF are closely related to thecardiac functional grading and poor prognosis.
