		                        			Objective:
		                        			To evaluate the comprehensive intervention effect of lunch for primary and secondary school students in Minhang District, so as to provide a theoretical and practical basis for lunch intervention in school.
		                        		
		                        			Methods:
		                        			From October to December 2023, a convenience sampling method was used to select 1 937 students from one primary and secondary school in Minhang District.A comprehensive intervention measure focusing on "reducing oil and salt" for lunch recipe optimization and nutrition education was carried out, and a questionnaire survey was conducted to evaluate the intervention effect three months later.  Chi square test and Wilcoxon rank test were used to compare the data before and after the intervention.
		                        		
		                        			Results:
		                        			After intervention, the use of cooking oil and salt, the supply of protein and fat in primary and secondary school lunches were reduced, and had no obvious impact on energy and other major nutrients. After intervention, compared to before intervention, the proportion of primary school students who felt that lunch was greasy decreased (8.9%, 6.2%,  χ 2=4.35), and the proportion of primary and secondary school students who felt that lunch were delicious decreased significantly (33.2%, 23.2%; 63.9%, 53.5%,  χ 2=26.39, 17.52) ( P < 0.05 ). Secondary school students also felt reduced variety of food ingredients (46.9%, 38.3%,  χ 2=16.05,  P <0.05). In addition, after intervention, the total surplus rate of primary school students  meals decreased (7.4%, 4.4%,  χ 2=5.73), mainly reflected in the decrease of the surplus rate of staple foods (7.1%, 2.4%,  χ 2=17.39), while the surplus rate of vegetable dishes increased ( 16.0 %, 21.2%,  χ 2=6.01) ( P <0.05). Although there was no significant change in the total surplus rate of meals for secondary school students, the surplus rate of staple foods decreased (12.9%, 5.4%,  χ 2=33.52), while the surplus rates of meat and vegetable dishes increased (11.2%, 26.9%; 17.5%, 33.2%,  χ 2=74.26, 61.88) ( P <0.05). After intervention, there was no statistically significant difference in the overweight and obesity rates of primary school students ( χ 2=0.11,0.43) and secondary school students ( χ 2=0.01,0.00) compared to before intervention( P >0.05). After intervention, the lung capacity of primary school students [1 564 (1 269,1 890) mL] and sitting forward flexion [11.3 (7.6, 15.2) cm] increased compared to before intervention [1 522 (1 259, 1 819 ) mL, 10.5 (6.3, 13.5) cm] ( Z =2.20, 4.68,  P <0.01), but there was no statistically significant difference in lung capacity and sitting forward flexion of secondary school students before and after intervention ( Z =-0.46, -0.08,  P >0.05).
		                        		
		                        			Conclusion
		                        			The comprehensive intervention of school lunch has promoted a significant decrease in the use of oil and salt in lunch and improved the quality of recipes, and has a positive impact on the situation of leftover lunch and the health of students to a certain extent.

		                        			Objective To identify long non-coding RNA (lncRNA) associated with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and investigate their mechanisms. Methods Peripheral blood samples were collected from RA-ILD patients (n=3), RA patients without lung involvement (n=3), and healthy controls (n=3). Next-generation sequencing was performed to screen differentially expressed lncRNA. A human fibrotic lung cell model was established by inducing the MRC-5 cell line with transforming growth factor-β (TGF-β). Following siRNA-mediated knockdown of target genes, changes in inflammatory and oxidative stress-related genes were analyzed via real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Western blotting and dual-luciferase reporter (DLR) assays were used to validate protein expression, ubiquitination levels, and nuclear translocation of oxidative stress regulators, and antioxidant response element (ARE) transcriptional activity. Rescue experiments were conducted to confirm the role of target lncRNA in oxidative stress and inflammation in fibrotic lung cells. Results High-throughput sequencing revealed significant downregulation of LINC00638 in RA-ILD patients. Knockdown of LINC00638 markedly reduced transcriptional levels of interleukin (IL)-4, nuclear factor erythroid-2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and superoxide dismutase 2 (SOD2), while increasing IL-6, IL-1β, interferon-γ (IFN-γ), and reactive oxygen species (ROS) levels. Furthermore, LINC00638 knockdown decreased Nrf2 protein expression, increased its ubiquitination, reduced nuclear translocation, and suppressed ARE transcriptional activity. In MRC-5 cells, LINC00638 knockdown combined with N-acetylcysteine treatment restored Nrf2 and HO-1 levels while reducing IL-6 expression. Conclusions LINC00638 suppresses inflammatory responses in RA-ILD by activating the Nrf2/ARE antioxidant signaling pathway, suggesting its potential as a therapeutic target for diagnosis and treatment.

		                        			Congenital myasthenic syndrome(CMS)is a group of neuromuscular transmission disorders caused by genetic defects,and it is characterized by an early age of onset,fatigable weakness of skeletal muscle,and a high disability rate,with respiratory failure as a common cause of death. Endplate acetylcholinesterase deficiency(EAD)caused by COLQ gene mutations is a subtype of CMS,and repetitive compound muscle action potential(R-CMAP)in nerve conduction examination is the key evidence for diagnosis. The heterogeneity of clinical phenotypes of CMS often leads to misdiagnosis or missed diagnosis,resulting in delayed treatment. This article reports a case of CMS caused by COLQ mutation and summarizes the pathogenesis,mechanisms,clinical manifestations,electrophysiological characteristics,differential diagnosis,treatment,and prognosis of the disease with reference to relevant literature,in order to improve the understanding of this subtype of CMS among clinicians.

		                        			Self-face is a unique and highly distinctive stimulus, not shared with others, and serves as a reliable marker of self-awareness. Compared to other faces, self-face processing exhibits several advantages, including the self-face recognition advantage, self-face attention advantage, and self-face positive processing advantage. The self-face recognition advantage manifests as faster and more accurate identification across different orientations and spatial frequency components, supported by enhanced early event-related potential (ERP) components, such as N170. Attentional biases toward self-face are evident in target detection during spatial tasks and the attentional blink effect in temporal paradigms. However, measurement sensitivity, perceptual load, and task demands contribute to some mixed findings. Positive biases further characterize the self-face processing advantage, with individuals perceiving their faces as more attractive or trustworthy than objective representations. These biases even extend to self-similar others, influencing social behaviors such as trust and voting preferences. Self-face processing advantages have been observed at an unconscious level and are regulated by several factors, including self-esteem, cultural differences, and multisensory integration. Cultural and individual differences play a crucial role in shaping self-face advantages. Individuals from Western cultures, which emphasize independent self-construal, exhibit stronger self-face biases compared to those from East Asian collectivist contexts. Self-esteem also modulates self-face advantages: high-self-esteem individuals generally maintain their self-face recognition advantage despite interference, exhibit attentional prioritization of self-faces, and demonstrate enhanced positive associations with subliminal self-faces. In contrast, low-self-esteem individuals display recognition vulnerabilities to social cues, show context-dependent attentional divergence (prioritizing others’ faces in task-oriented settings while prioritizing self-face in free-viewing tasks), and exhibit reversed positive associations with subliminal self-faces. Multisensory integration, such as synchronized visual-tactile cues, enhances self-face advantages and induces perceptual plasticity. This phenomenon is exemplified by the enfacement illusion, in which synchronous visual and tactile inputs update the mental representation of the self-face, leading to assimilation with another face. Neuroanatomically, self-face processing is predominantly lateralized to the right hemisphere and involves a network of brain regions, including the occipital lobe, temporal lobe, frontal lobe, insula, and cingulate gyrus. Disruptions in these networks are linked to self-face processing deficits in socio-cognitive disorders. For instance, autism spectrum disorder (ASD) and schizophrenia are associated with attenuated self-face advantages and abnormal neural activity in regions such as the right inferior frontal gyrus, insula, and posterior cingulate cortex. These findings suggest that self-face processing could serve as a potential biomarker for the early diagnosis and intervention of such disorders. In recent years, researchers have proposed various theoretical explanations for self-face processing and its advantage effects. However, some studies have reported no significant behavioral or neural advantages of self-faces over familiar faces, leaving the specificity of self-face a subject of debate. Further elucidation of self-face specificity requires the adoption of a face association paradigm, which controls for facial familiarity and helps determine whether qualitative differences exist between self-faces and familiar faces. Given the close relationship between self-face processing advantages and socio-cognitive disorders (e.g., ASD, schizophrenia), a deeper understanding of self-face specificity has the potential to provide critical insights into the early identification, classification, and intervention of these disorders. This research holds both theoretical significance and substantial social value.

		                        			ObjectiveFunctional near-infrared spectroscopy (fNIRS), a novel non-invasive technique for monitoring cerebral activity, can be integrated with upper limb rehabilitation robots to facilitate the real-time assessment of neurological rehabilitation outcomes. The rehabilitation robot is designed with 3 training modes: passive, active, and resistance. Among these, the resistance mode has been demonstrated to yield superior rehabilitative outcomes for patients with a certain level of muscle strength. The control modes in the resistance mode can be categorized into dynamic and static control. However, the effects of different control modes in the resistance mode on the motor function of patients with upper limb hemiplegia in stroke remain unclear. Furthermore, the effects of force, an important parameter of different control modes, on the activation of brain regions have rarely been reported. This study investigates the effects of dynamic and static resistance modes under varying resistance levels on cerebral functional alterations during motor rehabilitation in post-stroke patients. MethodsA cohort of 20 stroke patients with upper limb dysfunction was enrolled in the study, completing preparatory adaptive training followed by 3 intensity-level tasks across 2 motor paradigms. The bilateral prefrontal cortices (PFC), bilateral primary motor cortices (M1), bilateral primary somatosensory cortices (S1), and bilateral premotor and supplementary motor cortices (PM) were examined in both the resting and motor training states. The lateralization index (LI), phase locking value (PLV), network metrics were employed to examine cortical activation patterns and topological properties of brain connectivity. ResultsThe data indicated that both dynamic and static modes resulted in significantly greater activation of the contralateral M1 area and the ipsilateral PM area when compared to the resting state. The static patterns demonstrated a more pronounced activation in the contralateral M1 in comparison to the dynamic patterns. The results of brain network analysis revealed significant differences between the dynamic and resting states in the contralateral PFC area and contralateral M1 area (F=4.709, P=0.038), as well as in the contralateral PM area and ipsilateral M1 area (F=4.218, P=0.049). Moreover, the findings indicated a positive correlation between the activation of the M1 region and the increase in force in the dynamic mode, which was reversed in the static mode. ConclusionBoth dynamic and static resistance training modes have been demonstrated to activate the corresponding brain functional regions. Dynamic resistance modes elicit greater oxygen changes and connectivity to the region of interest (ROI) than static resistance modes. Furthermore, the effects of increasing force differ between the two modes. In patients who have suffered a stroke, dynamic modes may have a more pronounced effect on the activation of exercise-related functional brain regions.

		                        			OBJECTIVE To evaluate the effectiveness and safety of warfarin anticoagulation therapy guided by gene test in patients undergoing left ventricular assist device (LVAD) implantation, and to analyze the influencing factors of warfarin anticoagulation efficacy. METHODS Patients who underwent LVAD implantation at the Heart and Vascular Center of Northern Jiangsu People’s Hospital from January 2023 to October 2024 and required warfarin anticoagulant therapy were selected as the study subjects. They were divided into genetic testing group (n=51) and empirical treatment group (n=17) based on whether they underwent CYP2C9 and VKORC1 gene test. The gene test group was given warfarin based on the predicted dose calculated by gene test, while the empirical treatment group was given warfarin by clinical doctors based on international normalized ratio (INR) experience, all patients were given warfarin once a day. Follow-up observation was conducted for 6 months to compare the effectiveness [time in therapeutic range(TTR), the time required to reach INR for the first time, the incidence of embolic events, the incidence of INR<1.5 events] and safety (the incidence of major and minor bleeding events,the incidence of INR>3.5 events) of warfarin treatment between two groups of patients. According to whether the patient’s TTR was ≥60%, they were divided into TTR≥60% group (n=20) and TTR<60% group (n=48). Univariate and multivariate binary Logistic regression analysis were used to determine the factors affecting the anticoagulant effect of warfarin in patients. RESULTS The TTR of patients in the gene test group was significantly higher than that in the empirical treatment group (P<0.05). The incidence of INR<1.5 events in the gene test group was significantly lower than in the empirical treatment group (P<0.05). The incidence of minor bleeding events and INR>3.5 events in the gene test group were lower than in the empirical treatment group, but the difference was not statistically significant (P>0.05). The results of multivariate binary Logistic regression analysis showed that gene test was an independent protective factor for warfarin anticoagulant therapy [odds ratio (OR)=10.842, 95% confidence interval (CI): 1.211-27.037, P=0.033], and the combination of statins was an independent risk factor for warfarin anticoagulant therapy [OR=0.196, 95%CI: 0.045-0.861, P=0.031]. CONCLUSIONS Under the guidance of gene test, warfarin anticoagulation therapy for LVAD patients after implantation can improve TTR, shorten the anticoagulation target time, and has good safety; meanwhile, it should be noted that the combination of statins may enhance the anticoagulant effect of warfarin, thereby increasing the risk of bleeding in patients.

		                        			ObjectiveTo investigate the immunomodulatory effect of polysaccharides from Astragali Radix-Angelicae Sinensis Radix herb pair(Qi-gui polysaccharides) on lipopolysaccharide(LPS)-induced RAW264.7 macrophages and to characterize the structure of the active component Qi-gui homogeneous polysaccharide(AAPS-4a), and evaluate its protective effect on ulcerative colitis(UC). MethodsThe effects of six Qi-gui polysaccharides(0.01-100 mg·L-1) on the proliferation of RAW264.7 cells were assessed by cell proliferation and activity assay(CCK-8), and enzyme-linked immunosorbent assay(ELISA) was used to investigate the effects of the six polysaccharides(3, 10 mg·L-1) on the secretion levels of tumor necrosis factor(TNF)-α, interferon(IFN)-β, and nitric oxide(NO) in LPS-induced RAW264.7 cells. After screening for active polysaccharides, high-performance size-exclusion chromatography(HPSEC) was used to determine its homogeneity and relative molecular weight, then its characteristic functional groups were identified by Fourier transform infrared spectroscopy(FT-IR), monosaccharide composition was analyzed by high performance liquid chromatography(HPLC), methylation analysis combined with gas chromatography-mass spectrometry(GC-MS) was performed to determine the types and linkage modes of sugar residues, and one- and two-dimensional nuclear magnetic resonance(NMR) were used to identify the sugar residue composition and configuration of the active polysaccharide. Finally, experimental animals were divided into the normal group, model group, AAPS-4a low-dose group(50 mg·kg-1), AAPS-4a high-dose group(100 mg·kg-1), and sulfasalazine(SASP) group (75 mg·kg-1). Except for the normal group, the acute UC mouse model was induced using 3.5% dextran sulfate sodium salt(DSS). Each treatment group was administered the corresponding dose via oral gavage for 7 days, and changes in body weight were recorded. After treatment, the spleen index and disease activity index(DAI) score were calculated, TNF-α and interleukin-6(IL-6) levels in the serum were detected by ELISA, and histopathological changes in colon tissue were observed by hematoxylin-eosin(HE) staining. ResultsAt the cellular level, AAPS-4a exhibited a dose-dependent inhibition of LPS-induced increases in TNF-α, IFN-β, and NO levels(P<0.01). Structural characterization of AAPS-4a revealed that it was a homogeneous polysaccharide with a relative molecular weight of 7.6×103 Da, consisting of mannose(Man), glucose(Glc), and galactose(Gal) in a molar ratio of 1.3∶23.9∶1.0. It was primarily composed of five sugar residues of 1,6-α-D-Glcp, T-α-D-Glcp, 1,3-β-D-Galp, 1,4-α-D-Manp, and 1,2-α-D-Galp. In vivo experiments showed that compared with the normal group, the model group demonstrated markedly increased DAI score and spleen index, significantly reduced colon length, and significantly elevated levels of TNF-α and IL-6(P<0.01). Compared with the model group, the AAPS-4a high-dose group significantly reduced the DAI score and spleen index, as well as TNF-α and IL-6 levels, and improved colonic atrophy(P<0.05, P<0.01). Pathological observations showed that AAPS-4a significantly inhibited inflammatory cell infiltration in colon tissue and alleviated pathological damage. ConclusionAAPS-4a, a neutral homogeneous polysaccharide composed of 1,6-α-D-Glcp, T-α-D-Glcp, 1,3-β-D-Galp, 1,4-α-D-Manp and 1,2-α-D-Galp, is identified as a key bioactive component contributing to the anti-UC effect of the Qi-gui herb pair. Its immunoregulatory and anti-UC properties suggest its potential as a therapeutic agent for UC.

MethodsThoracoscopic instruments sterilized by STERRAD® 100NX hydrogen peroxide low temperature plasma in Shanghai Pulmonary Hospital affiliated to Tongji University from August to September 2024 were selected as the research items. According to the material of rigid containers, the instruments were divided into polyethylene case group (A), stainless steel case group (B) and silicone resin case group (C). In terms of the loading volume, the rigid containers were divided into (loading capacity <80%) groups of 8, 10 and 12 instruments. The results of physical monitoring, the first type of chemical indicator card monitoring, and the five types of card luminal chemical process challenge device (PCD) monitoring of the 9 groups of A8, A10, A12, B8, B10, B12, C8, C10 and C12 were compared and evaluated. ResultsCompared to A8, A10 A12, C8, C10 or C12 groups, the thoracoscope instruments in the stainless steel containers in B8, B10 or B12 group had higher hydrogen peroxide concentrations and shorter elapsed time in the pressure check phases 1 and phases 2, with the differences statistically significant (P<0.05), followed by the silicone resin case group and the polyethylene case group. The nine groups of physical parameter monitoring, the first type of chemical indicator monitoring, and the five types of chemical PCD monitoring for lumen sterilization achieved 100% qualification rates, and there were no significant differences in the qualified rates of sterilization among the 9 groups (P>0.05). ConclusionWhen using hydrogen peroxide low temperature plasma to sterilize thoracoscopic instruments, it is recommended to use stainless steel or silicone resin rigid containers with a controlled loading capacity (≤12) to ensure optimal sterilization quality.

		                        			OBJECTIVE To investigate the induction of apoptosis in hepatocellular carcinoma cells by polyphyllin 9 (PP9) through the regulation of the Fas/Fas ligand (FasL) signaling pathway, and its inhibitory effect on the growth of transplanted tumor in nude mice. METHODS Based on the screening of cell lines and intervention conditions, HepG2 cells were selected as the experimental subject to investigate the effects of 2 μmol/L and 4 μmol/L PP9 treatment on cell colony formation activity, apoptosis rate, as well as the protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3. Additionally, Fas inhibitor KR- 33493 was introduced to investigate the underlying mechanism of PP9’s anti-hepatocellular carcinoma activity. Using HepG2 cell tumor-bearing nude mice model as the object, and 5-fluorouracil (20 mg/kg) as the positive control, the effects of 10 mg/kg PP9 on tumor volume, tumor mass, and the protein expressions of the nuclear proliferation-associated antigen Ki-67 and cleaved caspase-3 in tumor-bearing nude mice were investigated. RESULTS Compared with the control group, 2, 4 μmol/L PP9 significantly decreased the number of clones and the clone formation rate of cells, but significantly increased the apoptosis rate, the protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3 (P<0.05 or P<0.01). However, the combination of Fas inhibitor KR-33493 could significantly reverse the effect of PP9 on the up-regulation of proteins related to the Fas/FasL signaling pathway (P<0.01). Compared with the control group, the tumor volume (on day 27), mass and protein expression of Ki- 67 in nude mice of the PP9 group were significantly decreased, while the protein expression of cleaved caspase-3 was significantly increased (P<0.01). CONCLUSIONS PP9 can induce apoptosis of HepG2 cells by activating the Fas/FasL signaling pathway. Meanwhile, PP9 can also effectively inhibit the growth of transplanted tumors in nude mice.

		                        			ObjectiveTo investigate whether there are differences in the efficacy of Gegen Qinliantang with different contents of Puerariae Lobatae Radix on the acute enteritis (AE) model mice and provide a scientific basis for the interpretation of Gegen Qinliantang in the treatment of "Xie Re Li". MethodsA total of 112 male BALB/c mice were randomly divided into a blank group,model group,single Puerariae Lobatae Radix group,non-Puerariae Lobatae Radix group,regular dose Gegen Qinliantang group (regular dose group),half-dose Puerariae Lobatae Radix group,and doubled-dose Puerariae Lobatae Radix group, with 16 mice in each group. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of the colon tissue. Western blot was employed to detect the expression of ZO-1 (a protein in the tight junction) and Occludin in the colon tissue, as well as the changes of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). ResultsCompared with the blank group,the DAI scores of the mice in the model group were significantly higher (P<0.05),and the histopathological sections of their colon tissues showed mucosal damage,glandular atrophy,disordered arrangement,and a large number of inflammatory cells infiltration,and the expression of ZO-1 and Occludin proteins in their colon tissues was significantly down-regulated (P<0.05,P<0.01). The expression of inflammatory factors TNF-α and IL-1β was significantly up-regulated (P<0.05,P<0.01). Compared with the model group,the DAI scores of mice in all dosing groups decreased significantly (P<0.05),with the most significant effect in the regular dose group. After 7 d of drug administration,the regular dose group had the best impact on the repair of colonic mucosa in the AE mouse model. The regular dose group significantly down-regulated the expression of TNF-α (P<0.05) and significantly up-regulated the expression of ZO-1 protein (P<0.05). The doubled-dose Puerariae Lobatae Radix group significantly down-regulated the expression of IL-1β protein (P<0.01),and there was no significant difference between all dosing groups and the model group in terms of the expression of Occludin protein. After 14 d of drug administration,the best effect on the repair of colonic mucosa in the AE mouse model was observed in the doubled dose Puerariae Lobatae Radix group. All groups except the non-Puerariae Lobatae Radix group significantly down-regulated the expression of TNF-α (P<0.01). Meanwhile,the regular dose group and doubled-dose Puerariae Lobatae Radix group significantly elevated the expression level of Occludin protein (P<0.01). The doubled-dose Puerariae Lobatae Radix group also significantly inhibited the expression of IL-1β protein (P<0.05) and up-regulated ZO-1 protein expression (P<0.05). ConclusionGegen Qinliantang can reduce the pathological damage of colon tissue, protect the barrier function and structure of intestinal epithelial cells, and reduce the expression of inflammatory factors, so as to achieve the therapeutic effect of AE model mice. When comparing the therapeutic efficacy of Gegen Qinliantang containing different Gegen contents, Gegen Qinliantang with the proportion of the original formula of Zhongjing was the most effective in AE model mice.
