ObjectiveThis study aims to systematically analyze the blood-absorbed components and metabolic profiles of Xiebaisan（XBS） in normal and chronic bronchitis （CB） mice using ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS）， while comparing differences between the two states. MethodsThirty female BABL/c mice were randomly divided into the normal group， the normal drug administration group， the CB group， the CB drug administration group and the dexamethasone group， with 6 mice in each group. The CB mouse model was established by inducing with ovalbumin （OVA）. The mice in the normal drug administration group and the CB drug administration group started to be gavaged with XBS（13.2 g·kg^-1） from the 21^st day， and the dexamethasone group mice were simultaneously gavaged with dexamethasone （0.5 mg·kg^-1） until the end of the 35^th day of the experiment. Subsequently， serum samples were collected and evaluated for their efficacy， based on the pharmacological evaluation indicators， to determine the efficacy of XBS in treating CB. Then the UPLC-Q-Exactive Orbitrap MS was employed to identify and analyze the chemical constituents， blood-absorbed components， and metabolites of XBS. Chemometric analysis was conducted to reveal metabolic profile differences under "dual states". Concurrently， Real-time PCR technology was utilized to detect the expression levels of key liver metabolic enzymes CYP2E1， CYP3A1， UGT1A1， and UGT1A6. ResultsA total of 28 prototype components and 158 metabolites （including 48 phase Ⅰ metabolites and 110 phase Ⅱ metabolites） of XBS were unambiguously identified in the serum of normal mice. Additionally， a comprehensive characterization was performed on a total of 32 prototype components and 178 metabolites （including 50 phase Ⅰ metabolites and 128 phase Ⅱ metabolites） of XBS in the serum of CB mice. Among them， 27 prototype components were detected in both states， including 12 flavonoids， 2 alkaloids， 3 triterpenes， 4 organic acids， 3 amides， 1 stilbene and 2 other compounds. The chemometrics analysis revealed no significant difference in the prototype components and metabolites of XBS between normal and CB mice； however， there was a significant increase in the in-vivo exposure of XBS in CB mice. Compared to normal mice， the levels of phase Ⅰ metabolites such as oxidation， reduction and methylation of blood components of XBS as well as phase Ⅱ metabolites of glucuronidation showed significant changes in CB mice. Real-time PCR further confirmed that these alterations were attributed to the upregulation of CYP2E1 （P<0.05）， CYP3A1 （P>0.05）， UGT1A1 （P<0.01） and UGT1A6 （P<0.01） enzymes expression in the liver of CB mice. ConclusionThis study elucidated the disparities in the levels of the blood-absorbed components and metabolic profiles of XBS in normal and CB mice， especially in oxidation， reduction， methylation in phase Ⅰ metabolism and glucoaldehyde acidification in phase Ⅱ metabolism. And there are related to the differences in the expression levels of phase Ⅰ and phase Ⅱ metabolic enzymes CYP2E1， CYP3A1， UGT1A1 and UGT1A6 in the liver.

Objective: To evaluate the effectiveness of school-family-community comprehensive intervention aimed at reducing sugar sweetened beverage(SSB) consumption among primary and secondary school students, so as to provide scientific basis for relevant departments to formulate campus sugar reduction measures for primary and secondary school students. Methods: In October 2023, a multi stage random cluster sampling method was used to select four primary schools (grade 4) and four junior high schools (grade 7) in Nanjing City, and they were randomly divided into the intervention group ( n =1 601) and the control group ( n = 1 433 ) (primary and secondary schools). The intervention group received a one year comprehensive intervention activity with the theme of “drinking less SSBs and enjoying a healthy life” for one consecutive year. The measures included the school conducting health education courses (once a month, 15 minutes each time), environmental support (posting promotional posters, changing them once a month), class bulletin board and interest projects (once a semester); interventions for families included conducting parent lectures (once per semester 30 min each time), new media (once a month) and hand in hand activities (once per semester); community carried out square promotion and create a supportive environment (post promotional posters and replace them once a month). The control group did not receive any intervention measures except regular health education classes. Self administered questionnaires were used to collect knowledge, attitudes, and intake of SSB at the baseline and after the intervention among primary and secondary school students. Results: After the intervention, the proportion of students in the intervention group with an SSB related knowledge awareness rate of 60% or above was 91.4%, which was higher than that of the control group (81.9%) ( χ 2=60.35, P < 0.01 ). The reporting rate of the behavior of choosing to drink beverages when thirsty in the intervention group was 25.4%, which was lower than that of the control group (33.3%); the reporting rates of informing parents about the hazards of sugar sweetened beverages and paying attention to nutrition labels were 62.0% and 78.0% respectively, both of which were higher than those of the control group (52.3%, 65.9%); the reporting rate of having sugar sweetened beverages at home frequently was 43.7% in the intervention group, which was lower than that of the control group (62.3%); the reporting rate of parents restricting the consumption of sugar sweetened beverages was 84.1%, which was higher than that of the control group (78.4%) ( χ 2= 22.66, 29.05, 54.40, 104.84, 16.24, all P <0.05). The reporting rate of students in the intervention group who consumed sugar sweetened beverages more than 4 times per week was 21.5%, which was lower than that of the control group (28.6%), and the difference was statistically significant ( χ 2=20.36, P <0.01). Conclusion The comprehensive intervention of school-family-community can effectively improve primary and secondary school students knowledge and attitudes regarding SSBs and reduce their consumption of these beverages.

Objective:To investigate the therapeutic effects of adeno-associated virus vector 5 (AAV5)-mediated hepatic lipoprotein lipase (LPL) expression on serum triglyceride (TG) metabolism and hypertriglyceridemic acute pancreatitis (HTG-AP) in mice.Methods:Ten male C57BL/6 Lpl+/- mice were randomly divided into two groups by a random number table: the Lpl+/- control group and the Lpl+/- gene therapy group, with five mice in each group. The Lpl+/- control group received a tail vein injection of AAV5 vector carrying the enhanced green fluorescent protein (EGFP) gene (AAV5-EGFP), while the Lpl+/- gene therapy group received a tail vein injection of AAV5 vector carrying the human LPLS447X gene (AAV5-LPLS447X). Oral fat tolerance tests were performed at 14, 28, and 56 days post-injection. Twenty wild-type ICR mice were randomly divided into a control group and a gene therapy group, with ten mice in each group. The ICR control group was injected with AAV5-EGFP, and the ICR gene therapy group was injected with AAV5-LPLS447X. Fourteen days after injection, the mice underwent intraperitoneal injection of P407 solution (0.5 g/kg) and caerulein (200 μg/kg) to induce HTG-AP. Serum TG, total cholesterol (TC), amylase, lipase levels, and plasma LPL activity after heparin injection were measured by microplate reader. Plasma LPL concentration was measured using an enzyme-linked immunosorbent assay (ELISA). LPL mRNA expression levels in the liver, heart, and adipose tissue of Lpl+/- mice were determined by quantitative reverse-transcription polymerase chain reaction (qRT-PCR). LPL protein expression in the liver tissue of ICR mice was detected by immunohistochemistry at 28 days after gene therapy. Histopathological changes in the pancreas were observed using hematoxylin-eosin staining. Results:Compared to the Lpl+/- control group, the Lpl+/- gene therapy group showed a significant decrease in serum TG levels starting from day 21. After oral administration of olive oil, the increase and peak of serum TG levels were significantly lower than those in the control group. Furthermore, hepatic LPL mRNA expression levels were significantly higher (1.96±0.11 vs 1.02±0.12) with statistical significance ( P<0.05). Compared to the ICR control group, the ICR gene therapy group showed a significant decrease in serum TG and TC levels, and plasma LPL activity (0.17±0.05 mEq/L·h -1vs 0.06±0.02 mEq/L·h -1) was significantly higher at 28 days after heparin injection with statistical significance (all P value <0.05). Immunohistochemical results showed high expression of LPL protein on the hepatocyte membrane in the liver of ICR gene therapy group mice. Moreover, pancreatic edema, inflammatory infiltration, and acinar cell necrosis were significantly alleviated compared to the control group. Conclusions:LPLS447X treatment can promote LPL expression in the liver of mice, significantly reduce TG levels, and alleviate the severity of HTG-AP.

Objective:To investigate the role of rheum tanguticum polysaccharide(RTP)in treating ulcerative colitis(UC)by improving intestinal flora.Methods:UC model was established,rats were divided into normal control group,model group and RTP treatment group.The integrity of colonic mucosa,submucosa and muscularis were observed by HE staining.Expressions of TNF-α,IL-6,IL-8 and IL-1β in serum were assessed by ELISA.16S rRNA sequencing was performed to analyze the composition and differences of intestinal flora in rats.Results:UC rats had symptoms such as loose stools,blood in the stool,anal filth,chills and mental malaise.RTP treatment could significantly improve the symptoms and reduce DAI scores(P<0.05).HE staining showed that the colonic struc-ture of UC rats was necrotic and inflammatory cells infiltrated submucosa.RTP treatment could significantly promote the repair and regeneration of mucosal epithelium.RTP could significantly inhibit inflammatory response and downregulate the expression of inflam-matory factors in UC rats(P<0.05).Composition and abundance of intestinal flora in UC rats were significantly different from that of normal control group.Staphylococcus was significantly increased,while Collinsella,Allobaculum,Chlamydia and Holdemanella were significantly decreased.RTP treatment could improve intestinal flora,reduce the abundance of Staphylococcus,and increase the abundance of Collinsella,Allobaculum,Chlamydia and Holdemanella.Conclusion:RTP can be used to treat UC in rats by inhibiting inflammation and improving intestinal flora.

Objective To explore the potential clinical value of the ratio of glycated albumin to albumin(GA/ALB)in the occurrence of heart failure(HF)among patients with coronary atherosclerotic heart disease(CHD).Methods A total of 337 CHD patients admitted to the Department of Cardiology in Shanxi Provincial People's Hospital from July 2023 to June 2024 were selected in this study.CHD patients were divided into HF group and non-HF group based on whether they progressed to HF.The clinical data and laboratory parame-ters of the two groups were compared.Restricted cubic spline curve was used to analyze the relationship be-tween GA/ALB levels and the risk of HF in CHD patients.Receiver operating characteristic curve was applied to evaluate the diagnostic efficacy of GA/ALB,GA,platelet to lymphocyte ratio(PLR),and monocyte to lym-phocyte ratio(MLR)in CHD patients with the occurrence of HF.Logistic regression was used to explore the relationship between serum GA/ALB levels and the risk of CHD patients occurrence of HF,and to analyze the degree of influence and stability of subgroup variables on results.Results There were statistically significant differences in GA/ALB,GA,PLR,MLR,and other indicators between the HF group and the non-HF group in CHD patients(P＜0.05).A non-linear relationship was observed between GA/ALB levels and the risk of HF in CHD patients.When the value of GA/ALB multiplied by 10 was less than 5.751,the risk of HF in CHD pa-tients increased with the increase of GA/ALB levels(P＜0.001).GA/ALB was an effective predictor for HF occurrence in CHD patients.Multivariable Logistic regression model showed that GA/ALB was an independ-ent risk factor for CHD patients with occurrence of HF.Subgroup analysis also confirmed the stability of GA/ALB in predicting the occurrence of HF in CHD patients.Conclusion GA/ALB is an independent risk factor for the occurrence of HF in CHD patients,and monitoring GA/ALB levels provides predictive value for the oc-currence of HF in these patients.

Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.
