Objective: To explore the association between vegetable intake with glucose and lipid metabolism levels among school aged children, so as to provide scientific basis for dietary intervention on children s metabolic health. Methods: Based on a natural population cohort in Jiulongpo District and Fengdu County of Chongqing, 2 133 school aged children aged 6-9 years were enrolled in the baseline survey in 2014, and 2 029 children completed the follow up in 2019. Questionnaire surveys were used to collect vegetable intake, general demographic and lifestyle data. Height, weight and waist circumference were measured, and glucose and lipid metabolism indicators such as fasting blood glucose (FBG), triglyceride (TG) and total cholesterol (TC), low densith lipoprotein triglyceride (LDL-C), high densith lipoprotein triglyceride (HDL-C) were detected. Mann-Whitney U test and Kruskal-Wallis H test were used for intergroup comparisons in multivariate analysis, and mixed effects linear regression model was used to analyze the association between vegetable intake and glucose and lipid metabolism. Results: The levels of FBG, TG, TC, HDL-C and LDL-C at baseline and follow up were [4.09(3.90,4.48), 0.84(0.60,1.14), 3.49(3.09,3.91), 1.25(1.09,1.46), 1.69 ( 1.39 ,2.02)；4.31(4.00,4.64), 0.92(0.71,1.22), 3.49(3.12,3.87), 1.36(1.16,1.57), 1.77(1.51,2.06)] mmol/L, respectively. Among these indicators, FBG, TG, HDL-C and LDL-C all increased significantly ( Z =-12.08, -7.82, -9.82, -5.37, all P < 0.01 ). The detection rate of low HDL-C levels at follow up (13.11%) was significantly lower than that at baseline (18.10%) ( χ 2=19.57, P <0.05). At baseline, there were significant differences in FBG, TC, TG, HDL-C and LDL-C among children with different vegetable intake levels ( H =68.47, 30.16, 11.02, 13.27, 44.70); at followup, only HDL-C showed significant intergroup differences ( H =13.10)(all P <0.05). Mixed effects linear regression model showed that after adjusting for confounding factors, vegetable intake was significantly negatively correlated with blood glucose levels among school aged children ( β=-0.03, 95%CI = -0.05 to -0.01, P <0.01). Conclusion Higher vegetable intake can independently reduce the risk of abnormal blood glucose in school aged children, which is of great significance for maintaining glucose metabolic health.

Objective: To investigate the association between body weight standardized vitamin B intakes and blood pressure among school aged children, so as to provide evidence for developing dietary guidance and intervention strategies of promoting healthy blood pressure in children. Methods: The data were derived from a pediatric health cohort established in both urban and rural areas of Chongqing. A total of 1 368 primary school students in grades one to three were recruited for the baseline survey between October and November 2014 by using a stratified cluster random sampling design. From February to March 2019, 1 283 participants completed the first follow up assessment. Dietary intake and sociodemographic characteristics were assessed using a food frequency questionnaire and a self administered questionnaire. Blood pressure, height, weight, and other anthropometric indicators were measured. Body weight standardized intakes of six B vitamins(B 1, B 2, B 3, B 6, B 9, and B 12 )were categorized into tertiles( T1-T 3). Linear mixed effects models were applied to examine the associations between body weight standardized vitamin B intakes and changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP). In addition, mixed effects Logistic regression models were used to assess the risk of elevated blood pressure. Results: Linear mixed effects model regression analyses showed that, after adjusting for potential confounders including age, sex, and family history of obesity, body weight standardized B vitamin intake was negatively associated with SBP, DBP, and MAP in school aged children ( β =-7.79 to -0.68, all P <0.05). Results from the mixed effects Logistic regression models showed that, compared with the T 1 group, children in the T 3 group had a lower risk of elevated blood pressure for vitamin B 1 ( OR=0.40, 95%CI =0.25-0.64), B 2 ( OR=0.36, 95%CI =0.23-0.58), B 3 ( OR=0.47, 95%CI =0.31-0.72, B 6 ( OR=0.37, 95%CI =0.22-0.60), B 9 ( OR=0.36, 95%CI =0.21-0.60), and B 12 ( OR= 0.56 , 95%CI =0.37-0.86)(all P <0.05). Conclusions Body weight standardized B vitamins were associated with changes in blood pressure levels and the risk of elevated blood pressure among school aged children. Ensuring sufficient dietary intakes of vitamin B may help prevent and control of abnormal blood pressure in children.

This study aims to investigate the therapeutic effect and mechanism of Daotan Xixin Decoction on APP/PS1 mice. Twelve APP/PS1 male mice were randomized into four groups: APP/PS1 and low-, medium-, and high-dose Daotan Xixin Decoction. Three C57BL/6 wild-type mice were used as the control group. The learning and memory abilities of mice in each group were examined by the Morris water maze test. The pathological changes of hippocampal nerve cells were observed by hematoxylin-eosin staining and Nissl staining. Immunohistochemistry was employed to detect the expression of β-amyloid(Aβ)_(1-42) in the hippocampal tissue. The high-dose Daotan Xixin Decoction group with significant therapeutic effects and the model group were selected for high-throughput sequencing. The differentially expressed gene(DEG) analysis, Gene Ontology(GO) analysis, Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis, and Gene Set Variation Analysis(GSVA) were performed on the sequencing results. RT-qPCR and Western blot were conducted to determine the mRNA and protein levels, respectively, of some DEGs. Compared with the APP/PS1 group, Daotan Xixin Decoction at different doses significantly improved the learning and memory abilities of APP/PS1 mice, ameliorated the neuropathological damage in the CA1 region of the hippocampus, increased the number of neurons, and decreased the deposition of Aβ_(1-42) in the brain. A total of 1 240 DEGs were screened out, including 634 genes with up-regulated expression and 606 genes with down-regulated expression. The GO analysis predicted the biological processes including RNA splicing and protein folding, the cellular components including spliceosome complexes and nuclear spots, and the molecular functions including unfolded protein binding and heat shock protein binding. The KEGG pathway enrichment analysis revealed the involvement of neurodegenerative disease pathways, amyotrophic lateral sclerosis, and splicing complexes. Further GSVA pathway enrichment analysis showed that the down-regulated pathways involved nuclear factor-κB(NF-κB)-mediated tumor necrosis factor-α(TNF-α) signaling pathway, UV response, and unfolded protein response, while the up-regulated pathways involved the Wnt/β-catenin signaling pathway. The results of RT-qPCR and Western blot showed that compared with the APP/PS1 group, Daotan Xixin Decoction at different doses down-regulated the mRNA and protein levels of signal transducer and activator of transcription 3(STAT3), NF-κB, and interleukin-6(IL-6) in the hippocampus. In conclusion, Daotan Xixin Decoction can improve the learning and memory abilities of APP/PS1 mice by regulating the STAT3/NF-κB/IL-6 signaling pathway.

OBJECTIVE: To investigate the effects of bone density, plate bending degree and proximal screw type on the stress fracture of clavicle hook. METHODS: Three sows weighing between 45 and 50 kg were selected, from which a total of 40 rivs were collected. The 15 ribs of sows were divided into 3 groups according to bone density and bone hardness with 5 rivs in each group. And then the 3 groups were fixed with 6-hole collarbone hook plates and 3 locking screws. Measure the maximum torsion force when the ribs were fractured by force. The same size 15 rids were divided into 3 groups, named forward bending group, 0° group(the angle between the plate surface and the rib surface) and reverse bending group. All fixed with 6-hole collarbone hook plates and locking screws to measure the maximum torsion force of rib stress fracture. Then the same size 10 rids were divided into 2 groups, the normal screw group and the locking screw group with 5 ribs in each group. Both groups were fixed with 6-hole collarbone hook plates and screws. The normal screw group was a normal screw, fixed in proximal end, and two locking screws. The locking screw group was fixed by locking screws. Measure the maximum torsion force of the two groups when the ribs fracture by force. RESULTS: In the bone density experiment, the torque force of hard bone group (104.51±6.27) N was greater than the normal bone group (75.04±3.81) N(t=8.979, P<0.05). The force of normal bone group was greater than the osteoporosis group (49.99±2.12) N(t=12.832, P<0.05). In the bending collarbone hook experiment, the order of the torque force generated by each group as follow:the forward bending group (343.59±6.18) N greater than the 0° group (106.01±5.29) N(t=65.279, P<0.05) greater than the reverse bending group (95.82±4.12) N(t=3.398, P<0.05). The force of the normal screw group (98.68±0.70) N was greater than the locking screw group (50.20±0.95) N(t=91.484, P<0.05). The data comparisons of each group were statistically significant. CONCLUSION Bone density, plate bending degree and proximal screw type had an impact on stress fracture of clavicle hook plate. Higher bone density, forward bending of the steel plate, and ordinary screws in proximal end can reduce the rates of stress fractures of clavicle hooks.

Objective To investigate the risk factors for the recurrence after endoscopic resection of colonic polyps from the toxin-grime theory proposed by Professor QIU Jian-Xing,and to construct the prediction model for predicting the risk of recurrence.Methods A retrospective analysis was conducted in 383 patients who underwent colonic polypectomy in the Department of Spleen and Stomach of Guangdong Second Traditional Chinese Medicine Hospital from January 2018 to June 2023.All of the patients underwent colonoscopy again during the period of one year to one year and a half after the operation.Of the 383 patients,254 patients relapsed and 129 patients did not relapse.Moreover,the data set of the 383 patients was randomly divided into a training set of 306 cases and a validation set of 77 cases at the ratio of 8 to 2.The risk factors related to the recurrence after colonic polypectomy were analyzed,and a logistic regression prediction model was established for verification.Results(1)In the recurrence-related factor analysis and model construction,logistic regression analysis results showed that related factors for the recurrence of colorectal polyps involved age(OR=1.03),hypertension(OR=2.91),body mass index(BMI)(OR=2.12),improper diet(OR=5.01),history of tobacco and alcohol(OR=2.24),history of use of psychotropic drugs(OR=2.44),damp-heat(OR=4.83),phlegm-retention(OR=3.24),blood stasis(OR=5.17),number of polyps(OR=1.38),diameter of polyps(OR=1.13),and pathological nature of polyps(OR=2.27),the difference being significant(P＜0.05 or P＜0.01).(2)The evaluation of the model showed that the area under the receiver operating characteristic(ROC)curve of the training set was 0.874(95％CI:0.834-0.914),and the area under the ROC curve of the validation set was 0.883(95％CI:0.806-0.961).The calibration curves of the training set and the validation set showed that the prediction accuracy of the model based on the above factors was reliable.(3)The clinical application of the model showed that the risk prediction can be performed by drawing a nomogram,and decision-making basis can be obtained after drawing a clinical decision curve and a clinical impact curve.Conclusion Age,hypertension,BMI,improper diet,history of tobacco and alcohol,history of use of psychotropic drugs,damp-heat,phlegm-retention,blood stasis,number of polyps,diameter of polyps and pathological nature of polyps are risk factors related to the recurrence of colorectal polyps.The prediction model based on the above factors has good discrimination and calibration,and can predict the probability of recurrence of colon polyps.

Purpose: Numerous studies have produced conflicting findings regarding the efficacy of statins in prostate cancer treatment. Our objective was to examine the correlation between statin usage and clinical outcomes in Taiwanese men with de novo metastatic prostate cancer. Materials and Methods: We identified patients diagnosed with de novo metastatic prostate cancer from the Chang Gung Research Database spanning the years 2007 to 2020. To minimize confounding bias, we employed the inverse probability of treatment weighting (IPTW) method. Clinical outcomes were assessed using IPTW-adjusted Kaplan-Meier curves. Multivariate Cox proportional hazard regression analysis was utilized to evaluate the association between mortality and clinical factors. Results: The study cohort comprised 1,716 statin users and 276 non-users. Patients who used statins exhibited a longer median overall survival (85.4 months compared to 58.2 months; p=0.001) and cancer-specific survival (112.6 months compared to 75.7 months; p<0.001) compared to non-users. The median time to the development of castration-resistant status was similar between statin users and non-users (p=0.069). Multivariable Cox proportional hazards regression analysis, after IPTW adjustment, demonstrated that statin use was associated with improved overall survival. Conclusions Our study indicates that the use of statins following a de novo metastatic prostate cancer diagnosis enhances survival outcomes. However, statins did not appear to delay the onset of castration-resistant status. Further large-scale and long-term studies are warranted to investigate the biological effects of statins in men with prostate cancer.

Objective:To investigate the efficacy and safety of a treatment regimen based on daratumumab in patients with high-risk relapsed refractory multiple myeloma(MM)with mSMART 3.0 score.Methods:Clinical data were collected from 16 patients with mSMART3.0 score high-risk relapsed refractory MM treated at the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from May 2020 to May 2023,all of whom received daltezumab-based regimen(regimen drugs including dexamethasone,isazomib,bortezomib,lenalidomide).The efficacy and safety of the treatment were retrospectively analyzed.Results:The median age of 16 patients was 63.5(47-70)years old,including 10 cases of IgG type,2 cases of IgA type,and 4 cases of light chain type.The curative efficacy was judged in all 16 patients,with an overall response rate of 93.75％(15/16),including 4 cases of strict complete remission(sCR),1 case of complete remission(CR),2 case of very good partial remission(VGPR),partial remission(PR)in 5 cases,and minor remission(MR)in 3 cases.The median follow-up time was 11(2-30)months,and the median progression-free survival and median overall survival were not achieved in 16 patients at the median follow-up period.The hematologic adverse effects of the treatment regimen using daratumumab-based were mainly neutropenia,and the non-hematologic adverse effects were mainly infusion-related adverse reactions and infections.Conclusion:Daratumumab-based regimen for the treatment of relapsed refractory MM patients with high risk of mSMART3.0 score has better efficacy and safety.

Objective:To investigate the association between the local renin-angiotensin system (RAS) in human follicular fluid (hFF) and age, ovarian function, in vitro fertilization (IVF) laboratory outcome. Methods:A non-intervention observational study was designed. hFF and medical case history without personal identity of patients who received IVF simply because of male factor infertility in Reproductive Medicine Center, the First Affiliated Hospital of Soochow University during January 2021 and February 2022 were collected. The renin, angiotensin converting enzyme (ACE), ACE2, angiotensin (Ang)Ⅱ and Ang 1-7 levels were detected by enzyme-linked immunosorbent assay kit. The correlation between age and RAS in hFF was analyzed by simple linear regression, and multivariate linear regression was used to further analyze the correlation between the RAS and IVF laboratory outcome.Results:1) A total of 139 samples of analysable hFF were obtained. 2) There was a linear negative correlation between age and renin (Pearson's r=-0.313 3, P<0.001), angiotensin converting enzyme (ACE; Pearson's r=-0.183 6, P=0.031), angiotensinⅡ (AngⅡ; Pearson's r=-0.218 6, P=0.010), ACE/ACE2 (Pearson's r=-0.319 2, P<0.001), AngⅡ/Ang1-7 (Pearson's r=-0.224 3, P=0.008), while the linear relationship with ACE2 and Ang1-7 was not significant (all P>0.05). 3) Basal follicle-stimulating hormone was positively correlated with age ( β=0.636, P<0.001), ACE2 ( β=0.267, P=0.026) and AngⅡ ( β=0.268, P=0.001), while negatively correlated with ACE ( β=-0.320, P<0.001) and Ang1-7 ( β=-0.217, P=0.014). Basal luteinizing hormone was positively correlated with AngⅡ ( β=0.330, P=0.003), while negative correlated with Ang1-7 ( β=-0.395, P=0.002). Antral follicle count was positively correlated with Ang1-7 ( β=0.153, P=0.049), while negatively correlated with age ( β=-0.869, P<0.001) and ACE2 ( β=-0.082, P=0.004). Basal anti-Müllerian hormone was only negatively correlated with age ( β=-0.349, P<0.001). There was no correlation between RAS and basal estradiol, progesterone, prolactin, testosterone (all P>0.05). 4) Oocyte retrieval count was positively correlated with renin ( β=0.146, P=0.014), AngⅡ ( β=0.113, P=0.034) and Ang1-7 ( β=0.185, P=0.002), while negatively correlated with age ( β=-0.717, P<0.001); MⅡ oocyte maturation rate was positively correlated with AngⅡ ( β=0.207, P=0.019) and Ang1-7 ( β=0.217, P=0.026), while negatively correlated with age ( β=-0.518, P<0.001). There was no correlation between RAS and the rates of two pronuclei embryos, transplantable embryos, high-quality embryos (all P>0.05). Conclusion:The local RAS in ovarian follicles is affected by age and correlated with ovarian function and IVF laboratory outcome.
