Objective: To investigate the association between the home food environment and overweight and obesity among primary school students, so as to provide scientific evidence for developing targeted family based intervention strategies. Methods: From May to June 2017, a total of 3 670 students in grades 4-6 were selected from 26 schools in 13 districts and counties of Shenyang using multistage random cluster sampling. A questionnaire survey was used to assess the home food environment and sociodemographic factors. Standardized physical examinations were conducted to measure height and weight, and overweight and obesity were defined according to the Screening for Overweight and Obesity among School age Children and Adolescents. Multivariable Logistic regression model was used to examine the association between the home food environment and overweight and obesity among primary school students. Results: Characteristics of the home food environment showed that "healthy cooking and seasoning" was the predominant household cooking pattern among primary school students, accounting for 2 119 students (57.7%), whereas "unhealthy cooking and seasoning" accounted for the lowest proportion, with 37 students(1.0%). Among households, the proportions of "often/always" available unhealthy foods were relatively high for candies(22.6%) and sugar sweetened beverages(19.2%). The mean score for household availability of unhealthy foods was (7.81±4.01). Multivariable Logistic regression analysis showed that, after adjustment for sex, age, family residence, and socioeconomic status, students from households with "unhealthy cooking and healthy seasoning" had a higher risk of overweight and obesity than those from households with "healthy cooking and seasoning" ( OR =1.60, 95% CI =1.03-2.46), the risk was even higher among students from households with "unhealthy cooking and seasoning" ( OR = 3.99 , 95% CI =2.03-7.86) (both P <0.05). Household availability of unhealthy foods was positively associated with overweight and obesity among primary school students. Each one point increase in the unhealthy food availability score was associated with a 7% increase in the risk of overweight and obesity ( OR =1.07, 95% CI =1.01-1.13); in addition, students from households where sugar sweetened beverages were "often/always" available had an increased risk of overweight and obesity ( OR=1.40, 95%CI =1.07- 1.86 ) (both P <0.05). Conclusions The home food environment is associated with the risk of overweight and obesity among primary school students. Improving household cooking practices and controlling the availability of unhealthy foods at home may contribute to the prevention and control of overweight and obesity among primary school students.

Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Gouty arthritis （GA） is caused by monosodium urate（MSU） deposition due to purine metabolism disorders. In traditional Chinese medicine （TCM）， it falls under the category of "dampness-heat Bi syndrome"， with core pathogenesis involving dampness-heat accumulation and dysfunction of the spleen and kidney. The dampness-heat syndrome is the most common and the primary syndrome type during acute attacks. In Western medicine， GA is associated with purine metabolism imbalance and inflammation triggered by MSU crystals， involving pathways such as NOD-like receptor protein 3 （NLRP3） inflammasome activation and Toll-like receptor 2/4 （TLR2/4） signaling. Clinically， colchicine and similar drugs are commonly used to treat GA， although long-term use carries potential side effects. Ermiao Formula analogs originate from ancient prescriptions， including Ermiao， Sanmiao， and Simiao compound formulas. All contain Atractylodis Rhizoma and Phellodendri Chinensis Cortex. Ermiaowan follow a 1∶1 formulation ratio. Sanmiaowan add Cyathulae Radix. Simiaowan further incorporate Coicis Semen. These formulas are rich in active ingredients， including alkaloids， terpenoids， flavonoids， and sterols， and treat GA through multi-component， multi-pathway， and multi-target mechanisms. Ermiaosan primarily exerts anti-inflammatory effects by inhibiting pathways such as TLR4/nuclear factor kappa-B （NF-κB） or regulating immune responses to reduce the release of inflammatory mediators， while also suppressing xanthine dehydrogenase （XDH） and xanthine oxidase （XO） activity to decrease uric acid production. Sanmiaowan enhance uric acid-lowering and anti-inflammatory effects through the guiding herb Cyathulae Radix， while also protecting cartilage from damage. Simiaowan utilizes Coicis Semen to regulate intestinal flora， alleviate dampness-heat symptoms， and exert multi-pathway anti-inflammatory and uric acid-lowering effects. The active ingredients contribute differently to uric acid metabolism regulation， anti-inflammation， antioxidant activity， and bone repair， resulting in varying therapeutic effects due to differences in formula composition. In summary， formulas derived from Ermiaosan demonstrate significant efficacy in treating dampness-heat type GA. This review summarizes their research progress and mechanisms， providing a reference for clinical application， new drug development， and further studies.

ObjectiveTo investigate the material basis of the pathogenesis of cerebral ischemic injury with blood stasis and toxin syndrome and to explore the protective effects of Huayu Jiedu prescription （HYJDP） on neutrophil extracellular trap-related cell death （NETosis） in cerebral ischemic injury following acute cerebral infarction. MethodsSeventy-two Sprague-Dawley （SD） rats were randomly divided into six groups （n=12 per group）： sham operation （Sham） group， blood stasis and toxin model （Model） group， low-， medium-， and high-dose HYJDP groups （HYJDP-L， HYJDP-M， and HYJDP-H； 9， 18， and 36 g·kg^-1， respectively）， and butylphthalide （NBP） group （0.06 g·kg^-1）. Except for the Sham group， rats in all other groups were subjected to carrageenan/dry yeast combined with a modified intraluminal filament method to establish a focal cerebral ischemia model of the middle cerebral artery with blood stasis and toxin syndrome. Neurological function was evaluated at 24 h after modeling using the Zea-Longa neurological deficit score. Cerebral infarction rate was assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining. Pathological morphology of brain tissue was observed using hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was used to determine serum levels of interleukin-8 （IL-8）， myeloperoxidase-DNA complexes （MPO-DNA）， and citrullinated histone H3 （CitH3）. Protein expression of phosphorylated phosphatidylinositol 3-kinase （p-PI3K）， protein kinase B （p-Akt）， mammalian target of rapamycin （p-mTOR）， sequestosome 1 （p62）， and CitH3 in brain tissue was detected by Western blot. Immunofluorescence （IF） was used to detect the expression of neutrophil-specific marker Ly6G， CitH3， and neuron-specific nuclear protein （NeuN） in brain tissue. ResultsCompared with the Sham group， neurological deficit scores and cerebral infarction rates in the model group were significantly increased （P<0.01 for both）. HE staining showed varying degrees of neuronal degeneration and necrosis， characterized by blurred neuronal structures， nuclear pyknosis and fragmentation， cytoplasmic dissolution into a vacuolated reticular pattern， and mild glial cell proliferation. ELISA results showed that serum levels of IL-8， MPO-DNA， and CitH3 were significantly increased （P<0.01）. Western blot analysis demonstrated decreased expression of p-PI3K， p-Akt， p-mTOR， and p62， while CitH3 expression was significantly increased （P<0.01）. IF results showed an increased number of NETs⁺ cells and a significant decrease in NeuN⁺ cells （P<0.01）. Compared with the Model group， neurological deficit scores in the HYJDP-H group were significantly decreased （P<0.05）， and cerebral infarction rates in the HYJDP-H and NBP groups were significantly reduced （P<0.01）. HE staining showed that brain tissue damage was markedly alleviated in the HYJDP-H group. ELISA results showed that levels of IL-8， MPO-DNA， and CitH3 were significantly decreased in the HYJDP-M， HYJDP-H， and NBP groups （P<0.01）. Western blot analysis showed that expression of p-PI3K， p-Akt， p-mTOR， and p62 was significantly increased in the HYJDP-H and NBP groups， while CitH3 expression was significantly reduced in all drug intervention groups （P<0.01）. IF results showed that the number of NETs⁺ cells was significantly decreased and the number of NeuN⁺ cells was significantly increased in all drug intervention groups （P<0.01）. ConclusionNETs may be the material basis of the pathogenesis of cerebral ischemic injury characterized by blood stasis and toxin. HYJDP can regulate the PI3K/Akt/mTOR signaling pathway， reduce the release of pro-inflammatory mediators and NETosis-related products， alleviate cerebral ischemic injury caused by autophagy-dependent NETosis， and thereby exert a neuroprotective effect.

Objective: To propose an improved method for constructing the internal quality control (IQC) framework for ELISA assays and validate its efficacy by statistically analyzing IQC data from nine blood center laboratories. Methods: 1) IQC data was collected from nine blood centers and analyzed using a domestic HBsAg ELISA detection kit as an example. 2) Differences between IQC values across batches within Blood Center 1 were assessed. 3) Statistical analyses were performed on batch usage, number of batches used, days of use, number of QC points, batch-specific means, and coefficients of variation (CV) across all nine centers. 4) Using the improved construction method for IQC framework, provisional and permanent frames were established for batches within Blood Center 1 and Blood Center 9, followed by outlier determination. Results: 1) Statistically significant differences were observed in IQC data between batches within Blood Center 1 (P<0.01). It is recommended that both the control material/reagents and the control chart framework be replaced simultaneously. 2) There were substantial differences among 9 blood centers regarding the control material/reagent lot numbers used, the number of QC runs per batch, and the QC values for identical lots. Therefore, individual laboratories should establish their own IQC chart frameworks. 3) The improved IQC framework construction method for ELISA assays is as follows: provisional frames are established via frame-shifting, using the pre-experimental mean and cumulative coefficient of variation (CV) from the preceding batch. For batches used >20 days with >20 QC points, permanent frames are constructed by aggregating in-control data accumulated over ≥20 days with ≥20 points to calculate cumulative mean and standard deviation. The provisional and permanent frames constructed by this method identified all 26 extreme outliers across Blood Centers 1 and 9 as out-of-control. Among the 218 general outliers, 10 were classified as normal by the provisional frames, while the remainder were designated as warnings or out-of-control. This method effectively monitors assay stability. Conclusion: Based on the statistical analysis of IQC practices across blood centers of varying scales, combined with the inherent characteristics of ELISA assays and the batch-to-batch instability of reagents/QC materials, it is recommended to reconstruct QC charts upon lot changes. The proposed method—utilizing frame-shifting for provisional frames and establishing permanent frames based on cumulative data—is applicable to blood center laboratories of differing sizes and effectively monitors the stability of the ELISA assay process.

AIM: To evaluate clinical efficacy of recombinant human epidermal growth factor(rhEGF)combined with adjuvant amniotic membrane transplantation in corneal alkaline burns. METHODS:In the prospective, randomized controlled study, patients with corneal alkaline burns treated in the hospital were enrolled between November 2022 and November 2024. After emergency treatment, patients were divided into combined treatment group and routine treatment group by random number table method. The routine treatment group was given basic treatment(rhEGF), while combined treatment group additionally underwent adjuvant amniotic membrane transplantation. The clinical efficacy, healing time of corneal epithelium, best corrected visual acuity, VAS scores, corneal neovascularization area, break-up time, score of corneal opacity, and levels of inflammatory factors(IL-6, hs-CRP, TNF-α)in the two groups were observed and compared. RESULTS:There were 110 patients(110 eyes)in this study, including 55 cases(55 eyes)in each group. The combination group had a mean age of 46.82±10.38 y, including 26 males and 29 females. The routine treatment group had a mean age of 45.13±11.57 y, with 31 males and 24 females. The total response rate of combined treatment group [94.5%(52/55)] was significantly higher than that of routine treatment group [81.8%(45/55), P<0.05]. The healing time of corneal epithelium in combined treatment group was significantly shorter than that in routine treatment group(P<0.001), and VAS score for pain severity after treatment was significantly lower than that in routine treatment group(P<0.001). The corneal neovascularization area in combined treatment group was significantly smaller than that in routine treatment group(P<0.001), break-up time was significantly longer than that in routine treatment group(P<0.001),and score of corneal opacity was significantly lower than that in routine treatment group(P<0.001). After treatment, levels of inflammatory factors in combined treatment group were significantly lower than those in routine treatment group(all P<0.05). CONCLUSION:Adjuvant amniotic membrane transplantation combined with rhEGF presents prominent clinical advantages in the treatment of alkaline corneal burns. It can enhance therapeutic efficacy, accelerate wound healing, relieve pain, reduce corneal neovascularization, prolong tear film break-up time, alleviate corneal opacification, and reduce the levels of inflammatory factors.

Objective:To explore the correlation between ASXL1 gene mutation characteristics and clinical manifestations and prognosis in patients with myelodysplastic syndrome(MDS).Methods:The clinical date of 264 patients with MDS in Xuzhou Central Hospital,Southeast University from August 2010 to April 2024 was retrospectively analyzed.The patients were divided into ASXL1wt group and ASXL1mut group according to the presence of ASXL1 gene mutation,and the correlation between gene mutation characteristics and clinical manifestations and prognosis was analyzed.Results:Compared with ASXL1wt group,the ASXL1mut group had a higher age of onset(P＜0.05),a higher proportion of males(P＜0.05),while the incidence of del(5q)was lower(P＜0.01).The mutation frequency of ASXL1 in MDS patients was 21.97％,and most of them were frameshift mutations.The p.Gly646fs was the most common amino acid variant,with a mutation frequency of 20.69％.The median overall survival(OS)and leukemia-free survival of patients with this sequence variant was 18.1 and 23.8 months,respectively,while in those without this sequence variant was 30 months and not reached,and the differences were statistically significant(P＜0.05).The results of multivariate analysis showed that the mutation of NRAS,WT1,KIT gene and the p.Gly646fs sequence mutation of ASXL1 gene were independent prognostic factors for OS in ASXL1mut patients.The median OS of ASXL1wt and ASXL1mut patients was 27.9(21.3-40.4)and 23.7(18.6-NA)months,respectively(P＞0.05).Among 58 ASXL1mut patients,5 cases(8.6％)transformed to acute leukemia,including 3 cases with RUNX1 mutation and 3 cases with TET2 mutation.Among 206 ASXL1wt patients,28 cases(13.6％)transformed to acute leukemia.The difference in leukemia transformation rate between the two groups was not statistically significant(P＞0.05).The efficacy of different treatment regimens was similar in the ASXL1mut group,while in the ASXL1wt group,patients receiving allogeneic hematopoietic stem cell transplantation had a significantly better prognosis than those receiving other treatment regimens(P＜0.001).The overall response rate to demethylation therapy was 68.7％and 67.6％in ASXL1mut and ASXL1wt group,respectively,and the difference between the two groups was not significant(P＞0.05).Conclusion:The overall survival of MDS patients with ASXL1mut is poor.The patients with p.Gly646fs sequence mutation have a higher proportion of bone marrow blasts and a worse prognosis.There are no statistical differences in efficacy of different treatment strategies in ASXL1mut group.ASXL1 mutation shows no significant effect on the response of MDS to hypomethylating agent therapy.

Objective·To explore the effects and potential mechanisms of emodin on Alzheimer's disease(AD).Methods·Wild-type C57BL/6J mice and 3×Tg-AD mice were divided into 6 groups:Control group(C57BL/6J mice),AD group(3×Tg-AD mice),Emodin 25 mg/kg group(3×Tg-AD mice+Emodin 25 mg/kg),Emodin 50 mg/kg group(3×Tg-AD mice+Emodin 50 mg/kg),Emodin 100 mg/kg group(3×Tg-AD mice+Emodin 100 mg/kg)and Donepezil group(3×Tg-AD mice+Donepezil 3 mg/kg).The Morris water maze test was used to evaluate the learning and memory abilities of mice.The expression of glial fibrillary acidic protein(GFAP),glucose-regulated protein 78kDa(GRP78),and inositol-requiring enzyme 1α(IRE1α)was detected by immunohistochemistry.The levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and IL-6 in brain tissue were measured by enzyme-linked immunosorbent assay(ELISA).Western blotting was used to detect the expression of NF-κB p65,p-NF-κB p65,p38,and p-p38 proteins.Results·Compared with the control group,mice in the AD group showed impaired cognition,increased GFAP expression,elevated levels of TNF-α,IL-1β and IL-6,and increased expression of GRP78 and IRE1α,along with enhanced phosphorylation of NF-κB p65 and p38.Compared with the AD group,emodin improved cognitive impairment of AD mice,inhibited astrocyte overactivation and neuroinflammation,and decreased the expression of GRP78,IRE1α,phosphorylated NF-κB p65,and phosphorylated p38 in brain tissue.Conclusion·Emodin can effectively improve cognitive impairment in AD mice,which may be related to the inhibition of endoplasmic reticulum stress-mediated neuroinflammation in astrocytes.

Objective To investigate the relationship between the appearance of ligand 1 in inflammatory fibroblasts,primary tumor-ous cells,tumor Impregna-ted immune-free cellulars and clinical pathologic signs in colorectal carcinoma.Methods The group meth-od of immunization was used,and PDGFRa and RGS5 were used to mark iCAF.The levels of PDGFRa,RGS5(mesenchyma,mesenchy-ma prior to tumor infiltration)and PD-L1 in TC and TIIC were detected in 120 CRC patients in our hospital from 2019 to 2021.To ana-lyze the relationship between the appearance of iCAF and PD-L1 in cancer tissues and clinical pathologic signs and overall survival(OS).Results The high rate of PDGFRa and RGS5 was 56.7％(68/120)and 47.5％(57/120)in the mesenchyma of 120 patients with colorectal carcinoma.The high detection rate of PDGFRa and RGS5 was 39.2％(47/120).The high surface level of PDGFRa and RGS5 is related to the emergence of neoplastic buds and the metastasis of luoba nodules in the region.The high surface reach rate of PDG-FRa was 71.7％(86/120)and that of RGS5 was 57.5％(69/120).The high detection rate of PDGFRa and RGS5 was 47.5％(57/120).The high surface level of PDGFRa and RGS5 is related to the emergence of tumor buds,the metastasis of lubaria in the region,and the phase of T.The positive rate of TC PD-L1 was 5.8％(7/120)and that of TIIC PD-L1 was 48.3％(58/120).The surface reach of TC PD-L1 is related to the regional luoba nodal transfer.Kaplan-Meier and Log-rank results were shown.The patient's OS was associated with histological grading,neoplasmic metastasis,neoplasmic budding,TIIC PD-L1,PDGFRa,and RGS5(mesenchyma,mesenchyma prior to neoplasmic infiltration).COX monofactor and polyfactor regression analysis showed:Histologic grading,luba metasta-sis,TIIC PD-L1,RGS5(mesenchyma,mesenchyma prelimbic)and PDGFRa(mesenchyma prelimbic)are independent of OS in pa-tients with CRCCreate a preemptive factor.The surface reach of PDGFRa(mesenchymal)was negatively correlated with that of TC PD-L1(r=-0.213,P=0.020).The surface reach of RGS5(mesenchymal)was negatively correlated with that of TC PD-L1(r=-0.183,P=0.046).Conclusion In CRC,iCAF has a negative correlation with TC PD-L1.Targeting the treatment of iCAF in CRC may benefit it,and the detection of TC PD-L1 and TIIC PD-L1 may provide reference for the therapeutic effect of clinical anti-epidem-ic therapy and the prediction of CRC.

Objective:To investigate the efficacy of nafamostat mesylate in traumatic extracorporeal membrane oxygenation (ECMO) therapy.Methods:Patients admitted to the intensive care units of Children's Hospital Affiliated to Xi'an Jiaotong University and Gansu Provincial Maternal and Child Health Hospital for ECMO-assisted cardiopulmonary support due to trauma from January 2021 to December 2024 were selected as the study subjects. Based on different anticoagulation strategies, patients were divided into the nafamostat mesylate group( n=11) and the common heparin group( n=10). The general conditions of the two groups were compared. In addition, differences in various clinical indicators during the ECMO-assisted process were compared, including white blood cell count (WBC), platelet count (PLT), hemoglobin level (Hb), hematocrit (HCT), prothrombin time(PT), activated partial thromboplastin time (APTT), thrombin time(TT), fibrinogen(FIB) and D-dimer. Furthermore，the differences in the total volume of component blood transfusions, coagulation substances, complications and prognosis between the two groups were compared. Results:No statistically significant differences were observed between the two groups regarding age, gender, weight, type of ECMO support, type of trauma, presence of active bleeding, or rate of surgical intervention. There were no statistically significant differences in WBC, PLT, Hb, HCT, PT, APTT, TT, FIB, and D-dimer between the two groups of patients prior to the initiation of ECMO support (all P>0.05). Compared with the common heparin group, children in the nafamostat mesylate group had lower PT[(21±6)s vs. (27±3)s; (20±4) vs. (28±5)], APTT[(68±8)s vs. (89±12)s; (64±15)s vs. (85±21)s], TT [(25±11)s vs. (31±13)s; (24±8)s vs. (35±6)s], and D-dimer[(5.8±1.1) μg/mL vs. (11.5±5.6) μg/mL; (4.2±1.8) μg/mL vs. (14.6±2.5) μg/mL],and higher FIB[(2.1±0.5) g/L vs. (1.6 ± 0.3) g/L; (2.4 ± 0.4) g/L vs. (1.3 ± 0.6) g/L] when ECMO assisted for 24 h and 72 h,the differences were all statistically significant(all P<0.05). Compared to the nafamostat mesylate group, the common heparin group exhibited significantly higher total cumulative infusion amounts of red blood cell suspension, plasma, platelet, FIB, hemocoagulase, and thromboplastin complex during the ECMO-assisted process, and the differences were statistically significant (all P<0.05). There was no statistically significant difference between the two groups of children in terms of time to ECMO assistance, membrane lung failure, loop thrombosis, embolism, and successful withdrawal rate (all P>0.05). Conclusion:Nafamostat mesylate can effectively reduce the risk of bleeding and minimize the requirement for blood product and coagulation substance infusions during traumatic ECMO assistance.
