Objective To investigate the activation of microglia and astrocytes, the secretion of pro-inflammatory factors, and the survival of neurons in the hippocampus of mice with acute seizures induced by pentylenetetrazol (PTZ) 24 hours after the onset of seizures. Methods Adult male C57BL/6 mice were randomly assigned to the control group and the PTZ-induced acute epileptic seizure group using random numbers, with 28 mice in each group. The activation status of microglia and astrocytes in the CA1 region of the hippocampus was evaluated by immunofluorescence 24 hours after the onset of seizures. RNA was extracted from the hippocampal tissue to detect the expression level of inflammatory factor mRNA, and HE staining was used to assess the survival of neurons in the hippocampus. Results Twenty-four hours after PTZ-induced acute seizures in mice, the numbers of activated Iba1+ microglia (55.72±4.29 vs 35.71±9.66, P<0.001) and GFAP+ astrocytes (51.61±8.21 vs 37.64±5.27, P<0.01) in the CA1 region were significantly increased compared with the control group; the proportion of M1 microglia was significantly increased (0.58±0.02 vs 0.35±0.08, P<

Objective:To present an evaluation indicator system for access to cancer screening services.Methods:The evaluation indicator pool was constructed through a scoping review. The theoretical framework was constructed based on the multi-source indicators, and the qualitative expert consultation method was employed to form the initial version of the three-level evaluation indicator system. Delphi expert consultation method was conducted in two rounds to evaluate the relevance, importance, and availability of the proposed evaluation indicator system. The expert positive coefficient, authority coefficient, coordination degree of expert opinions, and concentration of expert opinions were subjected to analysis. Subsequently, the three-level evaluation indicator system for access to cancer screening services was adjusted and determined based on the boundary value method and the open opinions of experts. Finally, the combination weight method was employed to determine the weight.Results:The initial version of the indicator system comprised 3 primary (first-level) indicators, 11 secondary (second-level) indicators, and 46 tertiary (third-level) indicators. Delphi expert consultation was conducted for the initial version, and 17 experts ultimately completed it, exhibiting a positive coefficient of 100% and an authority coefficient of 0.87. In comparison to the initial round of consultation, Kendall's W coefficient ranges (0.15-0.43, all P<0.05) of relevance, importance, and availability scores for each tertiary indicator in the second round exhibited an improvement. The analysis of the importance dimension indicates that expert opinions are also more concentrated, as evidenced by an increase of 8.5% and 7.0% in the proportion of the tertiary indicators with an arithmetic mean above 8 and a full mark ratio above 0.5, respectively. The final evaluation indicator system comprises three primary indicators, with the weights of structure evaluation, process evaluation, and outcome evaluation being 0.338, 0.378, and 0.285, respectively. It also comprises 11 secondary indicators and 45 tertiary indicators. Conclusions:The evaluation indicator system developed in this article can be an effective evaluation tool for quantitative comparison of access to cancer screening services across different populations, cancer types, and before and after intervention. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

Objective To analyze the identification of pathogenic bacteria in municipal sewage of Hangzhou City, Zhejiang Province from January to October 2023, to understand the serotype and drug resistance of Vibrio cholerae isolated from sewage, as well as to predict the virulence gene and drug resistance gene carrying situation. Methods From January to October 2023, urban sewage samples from various environments in Hangzhou City, Zhejiang Province, were continuously collected for bacterial isolation and culture. The serotypes of 27 Vibrio cholerae strains were identified by slide agglutination method, and the drug sensitivity test was conducted by micro broth dilution method. Whole genome sequence and bioinformatics software were used to predict drug resistance genes and virulence genes. Results The sewage identification results showed 26 bacteria genera, including Salmonella, Vibrio, Enterobacter, and Aeromonas, among 82 bacterial species. All 27 strains of Vibrio cholerae were non-O1 and non-O139 serogroups. The strains showed high resistance rates to ampicillin, ampicillin/sulbactam and cotrimoxazole at 59.26%, 14.81%, and 14.81%, respectively), exhibited high sensitivity to cefotaxime, tetracycline, chloramphenicol, meropenem, ertapenem, ceftazidime, ceftazidime/avibactam, amikacin, ciprofloxacin, tigecycline, and azithromycin. A total of 21 different drug resistance genes were detected in 11 strains of Vibrio cholerae, among which the highest carriage rate of β-lactam resistance genes reached 63.64%, and 1 strain carried 17 kinds of drug resistance genes. None of the 11 strains of Vibrio cholerae carried ctxA, ctxB, ace, zot, or chxA genes, but all the strains carried rtxB, rtxC, and rtxD genes; 90.91% of the strains carried hlyA, and 36.36% carried rtxA. Conclusions All Vibrio cholerae isolated from sewage in this study are non-O1 and non-O139 serogroups, showing good sensitivity to most antibiotics, but also they carry a certain number of drug-resistance genes and virulence genes. This suggests that future monitoring efforts should focus on these strains, providing certain data support for the study of the characteristics of Vibrio cholerae isolated from sewage.

Objective To investigate the equivalent conversion of head injury criterion(HIC)under anterior-posterior(AP)and lateral-medial(LM)craniocerebral impact for mild craniocerebral injury in rats using motor evoked potential(MEP)and β-amyloid precursor protein(β-APP)immunohistochemistry(IHC).Methods Sixty healthy adult male SD rats were randomly divided into 0 m control group,0.5 m-AP and 0.5 m-LM injury groups,and 1 m-AP and 1 m-LM injury groups(12 rats in each group).The control group did not undergo any impact injury experiment.After the impact injury experiment,the injury and control groups were subjected to excessive anesthesia to produce β-APP immunohistochemical stained slices,and the percentage of positive area and integral optical density(IOD)in the brainstem pyramidal tract area of the slices were determined.The MEP groups were divided in the same manner as the IHC groups and the MEP amplitudes of the MEP and control groups were measured after the impact injury experiment.Results With an increase in the degree of injury,the decrease in MEP amplitude,percentage of positive areas,and IOD in the injury groups significantly increased.When the degree of injury was low,the sensitivity of IHC was higher than that of MEP.When the degree of injury was the same,the HIC in the LM direction was lower than that in the AP direction.When the HIC was the same,the degree of injury in the LM direction was greater than that in the AP direction.Conclusions The joint evaluation of MEP and β-APP can provide experimental references for the study of HIC equivalent conversion in AP-LM craniocerebral impact injury.
