Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

A precursor ion selection (PIS) based ultra high performance liquid chromatography-quadrupole time of flight mass spectrometry (UHPLC-Q-TOF-MS) analytical method was used to screen the chemical components in Jiawei Dingzhi pills (JWDZP) comprehensively and rapidly. To compile the components of the compound medicine, a total of 1 921 components were found utilizing online databases and literature. After verifying the sources, unifying the component names, merging the multi-flavor attributed components, and removing the weak polar molecules, 450 components were successfully retained. The Acquity UPLC HSS T3 column (100 mm × 2.1 mm, 1.8 μm) was used, with a 0.1% formic acid water (A)-acetonitrile (B) as the mobile phase. The flow rate was 0.35 mL·min^-1, the column temperature was 35 ℃, and an electrospray ion source was used. Data was collected with the PIS strategy in both positive and negative ion modes. Compounds were screened through matching accurate molecular weight of the database, and identified according to MS/MS data (characteristic fragment ions and neutral loss), with comparison of reference. Some compounds were confirmed using standard products. A total of 176 compounds were screened out in the extract of JWDZP, among which 26 compounds were confirmed by standard products. These compounds include 96 components from the sovereign drug, and 34 coefflux components with low ion intensity. The PIS-UHPLC-Q-TOF-MS/MS method established in this study can quickly and comprehensively screen the chemical components of JWDZP, which enhanced the screening rate of components with co-elution compounds of low ion intensities and provided a basis for the study of the material foundation of JWDZP.

Objective To investigate the clinical efficacy of Xuanfei Yipi Formula,a prescription derived from modified Jianpi Pill recorded in Yi Fang Ji Jie(A Collection of Prescriptions with Expositions),in treating senile sarcopenia with spleen-stomach weakness type,and to observe its effect on chronic low-grade inflammation of the patients.Methods Seventy cases of senile sarcopenia patients of spleen-stomach weakness type were randomly divided into an observation group and a control group,with 35 cases in each group.The control group was given exercise and nutritional guidance,while the observation group was treated with Xuanfei Yipi Formula orally on the basis of the control group,and the intervention time of both groups was eight weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,appendicular skeletal muscle mass index(ASMI),grip strength,6-meter walking pace,and the serum levels of C-reactive protein(CRP),interleukin 6(IL-6),tumor necrosis factor α(TNF-α)in the two groups before and after treatment were observed.After treatment,the clinical efficacy and safety of the patients in the two groups were evaluated.Results(1)After eight weeks of treatment,the total effective rate in the observation group was 94.29%(33/35),and that in the control group was 77.14%(27/35),the intergroup comparison(by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the TCM syndrome scores in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of TCM syndrome score in the observation group was more obviously than that in the control group(P＜0.01).(3)After eight weeks of treatment,the ASMI,grip strength and 6-meter walking pace in the two groups were significantly higher than those before treatment,and the increase of ASMI and grip strength in the observation group was more obviously than that in the control group(P＜0.05).(4)After eight weeks of treatment,the levels of serum CRP,IL-6,and TNF-α in the two groups were decreased significantly compared with those before treatment(P＜0.05),and the decrease of serum CRP level in the observation group was more obviously than that in the control group(P＜0.05).(5)During the treatment,no obvious adverse reactions occurred in both groups,and the safety indexes of liver and kidney functions of the patients were all within the normal range.Conclusion Xuanfei Yipi Formula can improve the clinical symptoms of senile sarcopenia patients,and its mechanism is probably related with the regulation of chronic low-grade inflammation.

Background/Aims: Ubiquitination is widely involved in the progression of hepatocellular carcinoma (HCC) by regulating various cellular processes. However, systematic strategies for screening core ubiquitin-related genes, clarifying their functions and mechanisms, and ultimately developing potential therapeutics for patients with HCC are still lacking. Methods: Cox and LASSO regression analyses were performed to construct a ubiquitin-related gene prediction model for HCC. Loss- and gain-of-function studies, transcriptomic and metabolomics analysis were used to explore the function and mechanism of UBE2S on HCC cell glycolysis and growth. Results: Based on 1,423 ubiquitin-related genes, a four-gene signature was successfully constructed to evaluate the prognosis of patients with HCC. UBE2S was identified in this signature with the potential to predict the survival of patients with HCC. E2F2 transcriptionally upregulated UBE2S expression by directly binding to its promoter. UBE2S positively regulated glycolysis in a HIF-1α-dependent manner, thus promoting the proliferation of HCC cells. Mechanistically, UBE2S enhanced K11-linkage polyubiquitination at lysine residues 171 and 196 of VHL independent of E3 ligase, thereby indirectly stabilizing HIF-1α protein levels by mediating the degradation of VHL by the proteasome. In particular, the combination of cephalomannine, a small molecule compound that inhibits the expression of UBE2S, and PX-478, an inhibitor of HIF-1α, significantly improved the anti-tumor efficacy. Conclusions UBE2S is identified as a key biomarker in HCC among the thousands of ubiquitin-related genes and promotes glycolysis by E3 enzyme-independent ubiquitination, thus serving as a therapeutic target for the treatment of HCC.

OBJECTIVES: To investigate the association between maternal job burnout and adolescent depression and the mediating effect of maternal depression and parenting style. METHODS: A cross-sectional study was conducted. The cluster random sampling method was used to select 2 572 adolescents from 7 middle schools in Shanghai, China, from April to May, 2021. A survey was performed for these adolescents and their mothers. The research tools included a general information questionnaire, Maslach Burnout Inventory-General Survey, Center for Epidemiologic Studies Depression Scale, short-form of Egna Minnen av Barndoms Uppfostran, and Children's Depression Inventory. A structural equation model was established, and the Bootstrap method was used to investigate the mediating effect. RESULTS: The detection rate of depressive symptoms was 12.71% (327/2 572) among the adolescents. The scores of maternal job burnout, maternal depression, and negative parenting style were positively correlated with the score of adolescent depression (P<0.05), and the score of positive parenting style was negatively correlated with the score of adolescent depression (P<0.05). Maternal depression and parenting style played a mediating role between maternal job burnout and adolescent depression, including the individual mediating effect of maternal depression, the individual mediating effect of positive parenting style, and the chain mediating effect of maternal depression-negative/positive parenting style. CONCLUSIONS Maternal job burnout may affect adolescent depression through the mediating effect of depression, parenting style, and depression-parenting style, suggesting that the symptoms of adolescent depression can be reduced by alleviating maternal job burnout, improving maternal depression, increasing positive parenting behaviors, and reducing negative parenting behaviors.

Objective:To establish an animal model of acute systemic cold injury in mice.Methods:There were 98 C57BL/6 mice, half male and half female, with body weight of 22-27 g and age of 10 weeks. The mice were randomly divided into 7 groups ( n=14) according to the changes of anal temperature in cold environment, namely, group A (38.5 ± 1) ℃, group B (35 ± 1) ℃, group C (30 ± 1) ℃, group D (25 ± 1) ℃, group E (20 ± 1) ℃, group F (15 ± 1) ℃, and group G (10 ± 1) ℃, among which, group A was the blank control group, and the rest groups were the experimental group. The mice in the blank control group were placed in the normal environment (20 ± 5) ℃, and the mice in the experimental group were placed in the low temperature artificial climate box at - 20℃. The anal temperature of the mice was measured intermittently (as the core temperature), and the time required for the core temperature of the mice to drop to groups B, C, D, E, F and G was recorded. The righting reflex was used to evaluate the consciousness state, the action ability and the general state of each organ of mice were observed, and the blood routine and HE staining of each organ were detected. Results:The lower the core temperature of the experimental group, the longer the time required. The consciousness state, action ability, general state of organs, blood routine, and HE staining of organs in groups B, C, and D were basically the same as those in group A, and there was no acute systemic cold injury. Therefore, the blood routine, general observation of organs, and HE staining of organs in groups B, C, and D were no longer displayed compared with those in group A. Compared with group A, mice in group E began to suffer from disturbance of consciousness and action ability. With the decrease of core body temperature, the damage was aggravated, and mice in group G died. Compared with group A, the indices of blood routine test (WBC, RBC, HGB, PLT) of mice in group E began to decrease, and the univariate variance calculation showed that only WBC changes had statistical significance ( P<0.05). Compared with groups A and E, the indices of blood routine test (WBC, RBC, HGB, PLT) of mice in group F were further reduced, and the changes of each index in univariate variance calculation were statistically significant ( P<0.05). The general observation results showed that compared with group A, the lung, liver and spleen surfaces of mice in group E began to darken, and compared with groups A and E, the lung, liver, spleen, kidney and heart of mice in group F were further deepened and darkened, with irregular edges. HE staining results of various organs showed that compared with group A, the mice in group E began to have partial alveolar structure destruction and a small amount of inflammatory cell infiltration, the central vein of the liver was slightly congested, and the red and white pulp of the spleen were indistinct. Compared with groups A and E, the pathological structure damage of the lung, liver, spleen, kidney, heart and brain tissues of the mice in group F was further aggravated. Conclusions:Detection of consciousness state, action ability, general state of organs, blood routine and HE staining indices of organs in mice under low temperature can simulate the progress of clinical acute cold injury, and the animal model of acute systemic cold injury was successfully prepared.

Objective:To explore the prediction model of tissue chip technology for the chemotherapy response of patients with colorectal cancer.Methods:217 patients with colorectal cancer who had received standardized chemotherapy in the Affiliated People’s Hospital of Ningbo University from Jan. 2017 to Dec. 2019 were prospectively selected. The patients were randomly divided into training set (152 cases) and test set (65 cases) according to the ratio of 7:3, and were followed up for 6 months. The clinical data of the patients in the training set were compared, the expression levels of Ang-2, caspase-3 and CD147 in the patients were analyzed by tissue microarray technology, and the related factors affecting the responsiveness of colorectal cancer chemotherapy were analyzed by the Logistic regression model. R software was used based on the training set. A nomogram prediction model was built and model performance on the test set was evaluated.Results:One case was excluded from the training center, and 151 cases were finally included, including 93 cases in the chemotherapy response group and 58 cases in the chemotherapy response group. The tumor diameter, serum carcinoembryonic antigen, caspase3, Ang2 expression level, and the proportion of clinical stage IV in the poor chemotherapy group were significantly higher than those in the good chemotherapy group (all P<0.05) ; Logistic regression showed tumor diameter ( OR=2.394), serum carcinoembryonic antigen ( OR=1.878), caspase-3 ( OR=4.261), Ang-2 expression level ( OR=5.457), and clinical stage IV ( OR=5.954) were independent risk factors for adverse drug reactions in patients with colorectal cancer (all P<0.05). The consistency index (C-index) for predicting the factors related to adverse chemotherapy reactions in patients with colorectal cancer was 0.915. External verification showed that the sensitivity was 86.96%, the specificity was 92.50%, and the accuracy was 90.48% (42/65) . Conclusion:The expression levels of Ang-2 and caspase-3 are correlated with the responsiveness of colorectal cancer to chemotherapy, and can be used as predictive indicators to evaluate the responsiveness of colorectal cancer to chemotherapy.

Objective:To analyse the clinical characteristics and antiviral therapy in immunosuppressed hospitalized patients with influenza.Methods:The clinical data of 273 patients with positive influenza A or B virus nucleic acid admitted in Peking University People’s Hospital from November 2015 to March 2022 were retrospectively analyzed. Among them, 123 were immunosuppressed and 150 were non-immunosuppressed. The clinical characteristics and antiviral therapy in immunosuppressed patients with influenza were analyzed. SPSS 22.0 software was used to analyze the data.Results:Chemotherapy for malignancies was the most common cause of immunosuppression (61.8%, 76/123), followed by haemopoietic stem cell transplantation (24.4%, 30/123). The common symptoms were fever (93.5%, 115/123) and cough (41.5%, 51/123). The proportions of co-infections (22.8%, 28/123) and complications (43.9%, 54/123) in immunosuppressed hospitalized patients were higher than those in non-immunosuppressed patients ( χ2=9.365 and 7.496, both P<0.01). Compared with single drug therapy, combination of antiviral drugs did not shorten the fever time, negative conversion time of virus nucleic acid and the length of hospital stay, and reduce the death ( U/ χ2=312.5, 356.0, 749.5 and 0.185, all P>0.05). Compared to patients without corticosteroids use, the use of corticosteroids did not increase mortality in immunosuppressed patients ( χ2=2.508, P=0.113). Conclusions:Classical symptoms may be absent in immunosuppressed patients with influenza, and early detection of influenza virus is still an important means of early diagnosis. Co-infections and complications are more common in immunosuppressed influenza patients. Immunosuppressed influenza patients did not benefit from the combination of antiviral therapy.
