ObjectiveTo establish a qualitative and quantitative analysis method for chemical constituents in Liu Junzitang（LJZT）， and to clarify its material basis. MethodThe chemical constituents in LJZT were analyzed by ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）， and the resulting compounds were identified by using databases， such as MassBank， PubChem， ChemSpider， Traditional Chinese Medicine Systems Pharmacology Database and Analytical Platform（TCMSP）， and by combining with relevant literature. UPLC was used to establish a quantitative method for analysis of 9 compounds in LJZT， including liquiritin， hesperidin， lobetyolin， liquiritigenin， glycyrrhizic acid， nobiletin， tangeretin， atractylenolide Ⅱ and Ⅰ. ResultBy combining the relevant literature， database and MS information， a total of 79 compounds were identified from LJZT， including 31 flavonoids， 15 terpenoids， 14 nitrogen-containing compounds， 6 phenylpropanoids， 6 organic acids and 7 other compounds. The established quantitative analytical method for the nine representative components showed good linearity within their respective linear ranges， and the precision， stability， reproducibility and recovery were in accordance with the requirements. The quantitative results showed that the contents of liquiritin， hesperidin， lobetyolin， liquiritigenin， glycyrrhizic acid， nobiletin， tangeretin， atractylenolide Ⅱ and Ⅰ in LJZT were 0.376 5， 2.602 1， 0.082 6， 0.128 1， 1.778 6， 0.015 7， 0.006 7， 0.030 4， 0.003 2 mg·g^-1， respectively. ConclusionThe established method can quickly， sensitively and accurately analyze the chemical constituents in LJZT， clarify that the material basis of LJZT is mainly flavonoids， terpenoids and nitrogen-containing compounds， and simultaneously determine the contents of the 9 components， which can lay a foundation for the research on quality control， mechanism and clinical application of LJZT.

Objective: To elucidate the differences in manual acupuncture effectiveness at sensitized points by investigating the mechanisms of local skin action at different sensitization points in rats with knee osteoarthritis (KOA). Methods: Forty Sprague–Dawley rats were equally divided into control, model (1 mg of monoiodoacetate into the right knee joint cavity), sham operation, manual acupuncture at right Tianjing acupoint (MAR-SJ 10), and left SJ 10 groups. Safranine-O and fast green staining were used to assess the modeling. The morphological and functional changes in mast cells (MCs) were assessed during acupoint sensitization using toluidine blue and immunofluorescence staining. The levels of serotonin, histamine, substance P (SP), and tryptase at skin acupoints and serum levels of IL-β, IL-6, and TNF-α were detected using ELISA. Results: After 14 days of treatment, the number of MCs and their degranulation rates were statistically higher in the model group than in the control group (both P < .001). After applying acupuncture, the levels of 5-HT, HA, and SP at skin acupoints were lower than those in the model group (all P < .05), and tryptase level was higher (both P < .05). Tryptase level was higher on the skin at the MAL-SJ 10 acupoint than that on the MAR-SJ 10 acupoint (P = .004). Compared with the model group, the serum levels of IL-1β, IL-6, and TNF-α in the MAR-SJ 10 and MAL-SJ 10 groups were lower (all P < .05). Conclusion Acupuncture at KOA-sensitized acupoints mitigates joint injury in KOA rats and may bidirectionally regulate local MCs of these acupoints. This finding not only enhances the reference value of sensitizing points in clinical diagnosis and treatment, but also contributes to the understanding of the biological mechanisms underlying acupuncture intervention at sensitizing points.

Objective:To analyze the current situation and influencing factors of family economic burden in children with congeni-tal heart disease,and provide reference basis for relevant departments.Methods:Conduct a questionnaire survey on the parents of children with congenital heart disease,and use a multiple linear regression model to analyze the factors affecting the economic bur-den of the disease.Results:The median total economic burden of families with congenital heart disease is 44 140 yuan,which is higher than the average level of per capita disposable income among residents of Xinjiang from 2020-2022.The median direct non-medical economic burden is 2 700 yuan,and the median indirect economic burden is 2 890 yuan.The length of hospital stay and monthly household income are important factors affecting the total economic burden.Conclusion:The total economic burden of families with congenital heart disease is higher than the per capita disposable income.The more complex the condition,the longer the days of hospitalization and the longer the time lost from work,resulting in a higher overall financial burden.

Objective: To evaluate the preventive effect of implementing the free influenza vaccination policy on school absence among primary and secondary school students, so as to provide a reference for formulating and adjusting vaccination strategies. Methods: Among primary and secondary school students aged 6 to 18 in Longgang District, Shenzhen, they were divided into a vaccinated group (265 996 students) and an unvaccinated group (122 513 students) according to their influenza vaccination history during November 2023. Propensity score matching was used to conduct a 1∶1 match between the two groups to balance covariates. The number of absences per month was set as the dependent variable to construct a difference in differences model, and Poisson regression was employed to analyze the overall and multi time point effects. Results: Vaccination against influenza was associated with low rate of absenteeism among primary and secondary school students, with an overall preventive effect of 26.52% (95% CI = 23.47% -29.45%). The preventive effects in November (the month of vaccination) and December 2023, January and March 2024 were 42.12%, 40.12%, 30.33% and 20.91%, respectively. The preventive effect of the influenza vaccine on absenteeism among primary school students (26.39%) was not significantly different from that among secondary school students ( 27.97% ) ( P >0.05). The regression coefficient for class vaccination rates ranged from 0.998 to 0.999 ( P <0.01), indicating that for every 10% increase in influenza vaccination rates, absenteeism could be reduced by 1.5% to 2.2%. Conclusion Implementing free influenza vaccination for primary and secondary school students might help to reduce the risk of absenteeism, yielding significant socioeconomic benefits.

Two researchers trained in normative evidence-based methodology conducted literature screening, quality evaluation, and independent evidence extraction in accordance with the principle of evidence integration.Results:A total of 21 articles were included, including 1 clinical decision support, 8 guidelines, 3 expert consensus, and 9 systematic reviews. The best evidence summarized included 24 recommendations from 6 aspects, including screening objects, screening timing, screening practitioners, pre-screening assessment, screening tools and post-screening assessment, of which 70.8% was class 2b and above evidence, and 41.7% of the evidence was recommended with strength A.Conclusions:The literature on early identification of PSCI patients is of high quality and high level of evidence. The key to early identification of PSCI patients for medical professionals is to consider individual differences, select appropriate screening tools and conduct cognitive screening as soon as possible.

Objective:To explore the real maternal and infant care experience and needs of spouses of puerperal women, so as to provide a basis for improving maternal and infant care capacity and participation of spouses and promoting maternal and infant health.Methods:Guided by dyadic coping theory, the semi-structured interviews were conducted among 18 spouses of puerperal women who gave birth at the First Affiliated Hospital of Soochow University from July to September 2022 using the phenomenological research method, and the recording data were analyzed by Colaizzi phenomenon analytical method.Results:Three themes were extracted, including positive experience of maternal and infant care of spouses of puerperal women (positive psychological emotions, adjustment of perceptions and behaviors, understanding of social support), negative experience of maternal and infant care of spouses of puerperal women (negative psychological emotions, poor care competence, imbalance during life and work), diversified needs for maternal and infant care of spouses of puerperal women (the need for multidimensional knowledge and skills, the suggestion of building continuous health education platform, the expectation of support from family).Conclusions:Medical staff should provide the spouses of puerperal women with diversified maternal and infant care and professional continuing nursing according to their experience and needs. Meanwhile, the family support system should be improved to enhance their sense of competence and participation in maternal and infant care and promote maternal and infant health.

Acute kidney injury (AKI) is an important factor for the occurrence and development of CKD. The protective effect of dihydroartemisinin on AKI and and reported mechanism have not been reported. In this study, we used two animal models including ischemia-reperfusion and UUO, as well as a high-glucose-stimulated HK-2 cell model, to evaluate the protective effect of dihydroartemisinin on premature senescence of renal tubular epithelial cells in vitro and in vivo. We demonstrated that dihydroartemisinin improved renal aging and renal injury by activating autophagy. In addition, we found that co-treatment with chloroquine, an autophagy inhibitor, abolished the anti-renal aging effect of dihydroartemisinin in vitro. These findings suggested that activation of autophagy/elimination of senescent cell might be a useful strategy to prevent AKI/UUO induced renal tubular senescence and fibrosis.
