Objective To understand the awareness rate and willingness of parents of school-age infants and young children in Huangpu District, Shanghai to receive the 13 valent pneumococcal conjugate vaccine (PCV13) and its influencing factors, and to provide basic data for formulating community health education policies. Methods A stratified random sampling method was used to conduct a full coverage questionnaire survey on the PVC13 awareness rate and vaccination willingness of 1030 parents of infants and young children in 10 communities. Results A total of 1000 questionnaire surveys were completed, with an accurate response rate of 97.08%. The awareness rate of PCV13 was 85.50%, and the awareness rate of complications was less than 80%. The PCV13 vaccination rate was 55.60%. 38.74% of the reasons for not being vaccinated were concerned about vaccine side effects, and 32.21% were concerned about vaccine quality. The higher the education level of parents and the per capita annual income of the family, the higher the awareness rate of pneumococcal vaccine knowledge and the willingness to receive vaccination. Parents with registered residence in other places had low willingness to vaccinate PCV13. Conclusion The public has a higher awareness of PCV13 and a higher willingness to receive vaccination. It is necessary to strengthen the scientific popularization of complications of pneumococcal pneumonia and vaccine safety, strengthen vaccine safety supervision and disclosure of regulatory results, and strengthen PCV13 science popularization for parents of infants and young children with registered residence outside the city.

Circadian rhythm disruption is a universal phenomenon that is associated with a combination of internal and external factors, with internal factors referring to disturbances in the intrinsic regulatory mechanisms of sleep-wake behavior, and external factors including changes in sleep habits, severe sleep deprivation, shift work, social jet lag, prolonged exposure to nighttime light, and late nighttime eating. Shift work, as a common occupational factor, can lead to disruption of the central/ peripheral biological clock which regulates the expression of almost the entire genome, and the disruption of the biological clock can lead to genetic variants, hormonal secretion abnormalities, insulin resistance, oxidative stress, and systemic inflammation, which are risk factors for obesity. In the context of rapid advancement of global economy and industrialization, the prevalence of simple obesity in the traditional cognitive category is increasing in a linear trend, while the incidence of abdominal obesity, which is closely related to metabolic disorders, is also showing an increasing trend. In recent years, the mechanism of circadian rhythm disorder and obesity associated with shift work has attracted much attention, and this article summarized the latest research progress, aiming to provide a basis for the prevention and treatment of obesity caused by circadian rhythm disruption due to shift work.

Pharmaceutical cocrystals is an advanced technology to improve the physicochemical and biological properties of drugs. However, there are few studies on the in vivo metabolism of pharmaceutical cocrystals. In this study, the pharmacokinetics of wogonin cocrystal in normal rats was further studied on the basis of the previous preparation of wogonin-aloperine cocrystal. Firstly, an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was established for simultaneous determination of wogonin and its metabolite wogonoside in rat plasma, and to investigate the methodology. The method was applied to the pharmacokinetic study of wogonin-aloperine cocrystal (Wog-Alop) in rats. The results showed that wogonin and its metabolite wogonoside had a good linear relationship in the range of 1-800 ng·mL^-1, and the precision, accuracy, matrix effect and stability in this range met the requirements of biological analysis. Compared with direct administration of wogonin, the C_max of wogonin and its metabolite in rats increased to 7.44-fold and 9.15-fold, AUC_0-t increased to 1.67-fold and 3.72-fold, and oral bioavailability of wogonin increased to 187.66% after cocrystal administration. Wog-Alop cocrystal can significantly improve the C_max, AUC, and oral bioavailability of wogonin and its metabolite, which provides a new perspective for the clinical application of wogonin. This study was approved by the Experimental Animal Ethics Review Committee of Beijing University of Chinese Medicine (approval number: BUCM-2023032307-1148).

Due to the complexity of traditional Chinese medicine （TCM） interventions and the diversity of herbal components， single-omics technologies such as genomics， transcriptomics， proteomics， and metabolomics often cannot comprehensively elucidate the scientific connotations of TCM. Multi-omics technologies driven by system biology can analyze the theoretical connotations and application mechanisms of TCM from different levels such as genes， gene expression， proteins， and metabolites， in line with the holistic view of TCM， which helps to promote the modernization of TCM. By reviewing the literature on the application of omics technologies in the field of TCM， it is found that multi-omics technologies have been widely used in TCM for syndrome differentiation， evaluation of herbal quality， elucidation of pharmacological mechanisms， and drug toxicity assessment， providing comprehensive explanations of the mechanisms of action of TCM and overcoming the limitations of single-omics technologies， and having obtained significant achievements. However， multi-omics technologies also face challenges such as high cost， difficulties in data analysis due to large data volumes， and insufficient translation of research results. In the future， it is expected that through strengthening interdisciplinary cooperation， conducting long-term and dynamic clinical research， standardizing and normalizing data analysis processes， adopting appropriate and reasonable multi-omics integration patterns， establishing multi-omics databases for TCM， revealing the individualized characteristics， therapeutic mechanisms， and disease regulatory networks of TCM， the modernization of TCM will be promoted.

Objective To investigate the expression of centromere protein U(CENPU)in the intestinal tissues of patients with colon cancer,and to analyze the effect of CENPU expression level on the prognosis of patients with colon cancer combined with bioinformatics.Methods Firstly,the expression of CENPU in cancer tissues and normal tissues of colon cancer patients was analyzed by the expression of CENPU in tissues was further verified by real-time quantitative real time polymerase chain reaction(qRT-PCR),Western blot(WB)and immunohistochemistry(IHC).Combined with clinical data,univariate and multivariate Cox regression are used to analyze the correlation between CENPU expression and clinical case parameters of colon cancer patients.Then,the predictive effect of CENPU expression on the prognosis of colon cancer patients are explored by drawing receiver operating characteristic(ROC)curve and Kaplan-Meier survival curve.Finally,the possible molecular mechanism of the effect of CENPU expression on the progression of colon cancer are analyzed by bioinformatics.Results By qRT-PCR,WB and IHC experiments,we find that compared with normal tissues,the expression of CENPU in cancer tissues of colon cancer patients is significantly increased.Cox regression analysis show that the expression of CENPU is significantly correlated with the age and TNM stage of patients,and is a risk factor affecting the prognosis of patients.Kaplan-Meier survival curve analysis show that colon cancer patients with high CENPU expression has significantly lower survival rates.ROC curve show that the model based on CENPU expression has a high predictive power for the prognosis of colon cancer patients area under the curve(AUC=0.832).Bioinformatics analysis show that CENPI,CENPN,CENPD,CENPK,CENPP,CENPM,CENPQ,CENPH,NDC80 and ITGB3BP have significant interaction with CENPU gene.CENPU is involved in DNA repair,MYC/TARGETS/V1 and PI3K/AKT/MTOR signaling pathways.Conclusion High expression of CENPU in cancer tissues of patients with colon cancer is significantly associated with poor prognosis of patients,suggesting that CENPU is expected to be a potential target for early diagnosis and prognosis prediction of patients with colon cancer.
