Objective: To explore the association between body composition patterns and dyslipidemia in adolescents, so as to provide scientific evidence for developing strategies to prevent and manage dyslipidemia. Methods: A total of 1 371 adolescents aged 12-18 years were selected from Yinchuan City in 2020 and 2023 by using a combination of convenience sampling and stratified cluster sampling. All participants completed questionnaire surveys, physical examinations, body composition measurements and blood lipid tests. Principal component analysis was used to extract body composition patterns, and participants were divided into quartiles( Q 1- Q 4) based on the score of each factor. Logistic regression combined with restricted cubic spline (RCS) analysis was used to examine the associations between body composition patterns and dyslipidemia, and analyses were stratified by gender. Results: The prevalence of dyslipidemia among adolescents was 30.0%, with 27.4% for boys and 35.2% for girls. Principal component analysis extracted four body composition patterns:the fat mass pattern (eigenvalue=12.86, variance contribution rate=46.92%), the lean body mass pattern (eigenvalue=6.86, variance contribution rate=30.42%), the trunk dominant fat distribution pattern (eigenvalue=1.58, variance contribution rate=8.58%), and the trunk dominant lean body mass distribution pattern (eigenvalue=1.05, variance contribution rate=7.19%). According to the results of Logistic regression analysis, after adjusting confounding factors such as age, smoking, and alcohol consumption, compared with Q 1 group, adolescents in the Q 4 group of the fat mass pattern and the trunk dominant fat distribution pattern had increased risks of dyslipidemia ( OR =4.07,1.68), while adolescents in the Q 2 group of the lean body mass pattern had a decreased risk of dyslipidemia ( OR =0.59) (all P <0.05). RCS analysis showed nonlinear associations of the fat mass pattern and lean body mass pattern with dyslipidemia among adolescents (both P non-linearity <0.05), and the trunk dominant fat distribution pattern showed a linear association with dyslipidemia ( P-non linearity > 0.05 ). Among boys, the fat mass pattern and lean body mass pattern were associated with dyslipidemia ( OR =1.62,1.77), and a similar association for the fat mass pattern was also observed among girls ( OR =1.39)(all P <0.05). A similar association for the trunk dominant fat distribution pattern was observed only among boys （OR =1.46, P <0.05), with a significant gender interaction ( P interaction <0.05). Conclusions Increased fat mass and trunk fat accumulation in adolescents are associated with a higher risk of dyslipidemia, while moderate lean body mass plays a protective role. Controlling fat accumulation and maintaining appropriate lean body mass contribute to the prevention and management of dyslipidemia in adolescents.

AIM: To observe the clinical efficacy of Fuzheng Xiaoliu Granules in the treatment of stage II primary liver cancer and to explore its mechanism of action from the perspective of metabolomics. METHODS: Sixty patients with stage II primary liver cancer who achieved complete remission (CR) after comprehensive interventional therapy were randomly divided into treatment group and placebo group, with 30 patients in each group. They were treated for one year and observed for one year. The one-year recurrence rate, traditional chinese medicine (TCM) syndrome score, alpha-fetoprotein and child-pugh grade were compared between the two groups. The serum metabolites of the two groups before and after treatment were screened by ultra-high liquid chromatography-mass spectrometry technology, and the metabolic pathways and related biological pathways were analyzed. RESULTS: The one-year recurrence rate of the treatment group was significantly lower than that of the placebo group, and the overall improvement rate of TCM syndrome score was significantly better than that of the placebo group (P<0.05). There was no statistical significance in the comparison of alpha-fetoprotein and child-pugh grade between the two groups after treatment (P>0.05). Metabolomics results showed that there were 39 and 33 different metabolites in the treatment group before and after treatment and in the two groups after treatment, respectively. After enrichment analysis and topological analysis of the different metabolites, it was found that Fuzheng Xiaoliu Granules could affect amino acid metabolism, fatty acid metabolism and purine metabolism and other metabolic pathways. Before and after treatment in the treatment group and after treatment in the two groups, there were the same differential metabolites and metabolic pathways in the two comparison results. The same differential metabolites with FOLD CHANGE>1 include Stearic acid, Hypoxanthine, Kynurenic acid, Arachidonic acid, and N-Arachidonoyl Dopamine. The same metabolic pathways with Impact>0.1 include Arachidonic acid metabolism and Histidine metabolism. CONCLUSION: Fuzheng xiaoliu granules can effectively reduce the recurrence rate of stage II liver cancer patients after comprehensive intervention and improve the TCM syndrome. It may inhibit the activation of PI3K/Akt and ERK signaling pathways by regulating the content of metabolites involved in metabolic pathways such as amino acids and fatty acids, thereby delaying tumor recurrence.

There is still a lack of effective strategies for the prevention and treatment of liver cancer, and a deep understanding of its pathogenesis may help to develop new treatment methods. Due to the abnormal changes of lipid metabolism in the development and progression of liver cancer, such process is closely associated with the "phlegm-turbidity" theory in traditional Chinese medicine (TCM). Starting from the changes of lipid metabolism in hepatocellular carcinoma microenvironment, this article discusses the association of the abnormal changes of lipid metabolism in tumor cells and immune cells with the "phlegm-turbidity" theory and the clinical efficacy of phlegm-eliminating therapies in clinical practice. Since the "phlegm-turbidity" theory in TCM plays an important role in the pathogenesis and pathological changes of liver cancer, the analysis of its theoretical connotation helps to clarify pathological mechanism, thereby providing a theoretical basis for the role of TCM in the prevention and treatment of liver cancer.

Objective To investigate the effect of up-regulation of miR-132 on expressions of angiopoietin-1 (Ang-1)/endothelium-specific tyrosine kinase receptor 2 (Tie2) in focal cerebral ischemia reperfusion injury of rats.Methods Forty adult healthy SD rats were randomly divided into sham-operated group,cerebral ischemia group,miR-132 mimic group and negative control group (n=10).The models of middle cerebral artery occlusion in the later three groups were established by using modified Longa suture method.Rats in the miR-132 mimic group and negative control group were injected miR-132 mimic 15 μg and negative control 15 μg via paracele.Rats in each group were sacrificed 24 h after ischemia,and the brain tissues were collected;the total infarct volumes were calculated by TTC staining.The mRNA expressions ofmiR-132,Ang-1 and Tie2 in ischemic cerebral cortex tissues were detected by real-time fluorescence quantitative PCR.The protein expressions of Ang-1,Tie2,CD31 and vessel endothelial growth factor (VEGF) in ischemic cerebral cortex tissues were detected by Western blotting.Results The total infarct volume in the miR-132 mimic group was (27.92±3.05) mm3,which was significantly smaller than that in the cerebral ischemia group and negative control group ([51.34±2.86] mm3 and [50.46±2.57] mm3,P＜0.05).The relative mRNA expression levels of miR-132,A ng-1,Tie2,and the protein expression levels of Ang-1,Tie2,CD31,VEGF in the ischemic cerebral cortex tissues of the miR-132 mimic group were significantly higher than those in the negative control group,cerebral ischemia group and sham-operated group (P＜0.05);and those in the negative control group and cerebral ischemia group were significantly higher than those in the sham-operated group (P＜0.05).Conclusion Up-regulation ofmiR-132 expression could improve the ischemic states of ischemic stroke in rats,which might be related to Ang-1/Tie2 increased expressions to promote angiogenesis in ischemic brain tissues.

Objective To study the clinical curative effect of Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen for treatment of delayed encephalopathy after carbon monoxide poisoning (DEACMP). Methods A prospective study was conducted. Forty-six patients with DEACMP admitted into Yidu Central Hospital of Weifang Medical College from January 2012 to January 2014 were randomly divided into observation group (23 cases) and control group (23 cases). The basic treatments of two groups were identical. Based on the basic treatments including hyperbaric oxygen and citicoline sodium injection etc, the observation group was treated with our-self made Tongqiao Huoxue decoction which could be modified in accord to the individual differentiation of syndromes in traditional Chinese medicine (the composition of decoction included Paeoniae Radix Rubra 15 g, Chuanxiong Rhizoma 15 g, Persicae Semen 15 g, Carthami Flos 15 g, Zingiberis Rhizoma Recens 3 pieces, Jujubae Fructus 2 pieces, Moschus 0.5 g, Allium Fistulosum 1 segment). The decoction was administered orally or by nasogastric gavage, one dosage everyday for 1 month, and in the mean time, edaravone intravenously drip 30 mg was given to the observation group twice a day for 14 days. The control group was given hyperbaric oxygen and other conventional treatment for 30 days. The clinical therapeutic effect and adverse reaction were observed after treatment for 30 days. The changes of intelligent level were detected by Hasegawa dementia scale (HDS), and the changes of latency of P300 were measured by electromyologram/evoked potential instrument in two groups before and after treatment. Results The total effective rate in observation group was significantly higher than that in control group [91.3% (21/23) vs. 65.2% (15/23), P < 0.01]. Elevation of creatinine occurred in 1 case, moderate increase in alanine aminotransferase (ALT) appeared in 1 case, and both of them were reduced to normal after treatment in observation group; no adverse reaction occurred in control group. The HDS scores were significantly higher 30 days after treatment than those before treatment in the two groups [control group:13.4±2.8 vs. 6.8±2.3, observation group:20.8±3.4 vs. 6.6±2.5, both P<0.05]. The latency of P300 after treatment was significantly lower in two groups than that before treatment [control group (ms): 355.7±25.7 vs. 385.5±27.8, observation group (ms): 337.3±24.6 vs. 386.8±25.4, both P < 0.05], the change in observation group being more significant [the HDS score: 20.8±3.4 vs. 13.4±2.8, the latency of P300 (ms): 337.3±24.6 vs. 355.7±25.7, both P<0.05]. Conclusion Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen has favorable cognitive effect on patients with DEACMP, thus, it can be used extensively in clinic.
