ObjectiveTo explore the role and molecular mechanism of Weifuchun （WFC） in inhibiting inflammation and alleviating gastric precancerous lesions （GPL）. MethodHuman gastric mucosal epithelial cells （GES-1） were stimulated with N-methyl-N′-nitro-N-nitrosoguanidine （MNNG） for the modeling of GPL （MC cells）， with Caspase-3 inhibition by Z-DEVD-FMK. MC cells were divided into control （20% blank serum）， WFC （15% and 20% WFC-containing serum）， and caspase-3 inhibitor groups. The cell counting kit-8 （CCK-8） was used to examine the viability of GES-1 cells or MC cells. The Transwell assay and 5-acetylidene-2′-deoxyuridine （EdU） staining were employed to examine cell invasion and proliferation， respectively. Flow cytometry was employed to determine the level of reactive oxygen species. Real-time PCR was conducted to determine the mRNA levels of interleukin （IL）-1， IL-6， and tumor necrosis factor （TNF）-α. Gene Expression Omnibus （GEO） was used to analyze the role of pyroptosis in gastric cancer progression. Western blotting was employed to determine the protein levels of nuclear factor-κB （NF-κB） p65， gasdermin E （GSDME）， and Caspase-3. Immunofluorescence staining was employed to detect the NF-κB p65 protein level and nuclear translocation. Hematoxylin-eosin staining was carried out to observe the pathological changes in the gastric mucosa before and after WFC treatment in the patients. ResultCompared with the control group， MC cells presented enhanced proliferation and invasion energy （P<0.01）. Compared with the blank serum group， WFC-containing serum inhibited the proliferation and invasion of MC cells （P<0.01）， down-regulated the mRNA levels of IL-1， IL-6， and TNF-α， and lowered the level of reactive oxygen species （P<0.05， P<0.01）. The transcriptome data at different stages of gastric cancer showed that pyroptosis was involved in gastric cancer progression， and the GSDME level was significantly higher in GPL patients than in the normal group. Compared with the blank serum， WFC-containing serum lowered the level of NF-κB and inhibited the nuclear translocation of NF-κB （P<0.05）， and it inhibited pyroptosis by suppressing the cleavage of Caspase-3 on GSDME （P<0.05， P<0.01）. The analysis of patient specimens further demonstrated that WFC treatment down-regulated the NF-κB level and GSDME cleavage （P<0.01）， inhibited pyroptosis， and alleviated gastric mucosal inflammation and intestinal epithelial metaplasia. ConclusionPyroptosis is involved in the progression of gastric cancer， and WFC inhibits pyroptosis via the NF-κB/GSDME pathway， thereby alleviating gastric mucosal inflammation in GPL.

OBJECTIVE To preliminary predict and analyze the quality marker(Q-markers)of Platycodonis Radix decoction based on the validity and measurability of traditional Chinese medicine Q-marker. METHODS The fingerprints of 20 batches of Platycodonis Radix samples were established, and the similarity was evaluated. At the same time, a "component-target-pathway" network diagram was constructed through network pharmacology to predict the potential active components of Platycodonis Radix. Mathematical analysis methods such as principal component analysis and orthogonal partial least-squares discrimination analysis were used to screen differential components; the content of candidate components were determined. RESULTS There were 19 common peaks in the established fingerprint, and 8 common components were identified as candidate active components for network pharmacology analysis. Network pharmacology indicated that 6 compounds were screened out with a high degree of connectivity. Based on the comprehensive consideration of Q-marker principle:traceability and transmissibility, specificity, efficacy, and measurability, luteolin, syringin, chlorogen acid, platycoside D, platycoside D3 and platycoside E were preliminarily predicted as potential Q-markers of platycodon. CONCLUSION The prediction analysis of Platycodonis Radix Q-marker provides a reference for the comprehensive control of the quality of Platycodonis Radix medicinal materials, and also lays a foundation for the research and exploration of the substance basis and mechanism of action of Platycodonis Radix.

Objective:To construct a quality evaluation index system for postoperative rehabilitation in children with developmental dislocation of the hip (DDH) .Methods:From August to November 2021, a quality evaluation index system for postoperative rehabilitation in children with DDH was established through literature review, group discussion, and Delphi expert consultation. The analytic hierarchy process was used to determine the weights of various indicators. The positive coefficient of experts was expressed by the effective response rate of the questionnaire. The authority level of experts was represented by the authority coefficient ( Cr) , which was determined by the expert judgment coefficient ( Ca) and the expert familiarity level ( Cs) . The degree of coordination of expert opinions was represented by the Kendall harmony coefficient (Kendall's W) . The degree of concentration of expert opinions was represented by the average score of importance assignment, coefficient of variation, and full score rate. Results:The effective response rates of the two rounds of expert consultation questionnaires were 90.00% and 100.00%, respectively. The Cr of experts in two rounds were 0.785 and 0.815, and the Kendall harmony coefficients were 0.098-0.193 and 0.147-0.212 ( P<0.05) . In the second round of expert consultation, the average scores of importance assignment for all levels of indicators were≥4.0, with coefficients of variation of 0-0.24 and a full score rate of ≥50%. The final quality evaluation index system for postoperative rehabilitation in children with DDH included 3 first-level indicators, 9 second-level indicators, and 37 third-level indicators. In the consistency test results of each indicator at all levels, all of the CI were <0.001, and all of the CR were<0.001. Conclusions:The construction process of the quality evaluation index system for postoperative rehabilitation in children with DDH is scientific, and the weight distribution of the indicators is reasonable, which can be used as an effective tool for evaluating the postoperative rehabilitation quality of DDH children.

Objective:To explore the application effect of family-centered empowerment model (FCEM) in rehabilitation nursing of children with femoral shaft fractures treated by skin traction.Methods:A retrospective case-control study was conducted to analyze the clinical data of 107 children with femoral shaft fractures treated with skin traction in Anhui Children′s Hospital from April 2019 to October 2021, including 67 males and 40 females; aged 1.5-5.0 years [2.8(2.0, 3.5)years]. Fracture types included oblique fracture ( n=50), comminuted fracture ( n=26), transverse fracture ( n=14) and spiral fracture ( n=17). FCEM nursing was implemented in 55 patients (family empowerment group) and routine home rehabilitation nursing guidance was performed in 52 patients (routine nursing group). The face, legs, activity, cry, consolability (FLACC) behavioral score on admission and at days 1, 3 and 7 after skin traction, treatment compliance rate at 1 month after skin traction, complication rate at 1 month after skin traction, length of hospital stay and fracture healing time were compared between the two groups. Results:All patients were followed up for 12-18 weeks [13.4(12.7, 13.9)weeks]. There was no significant difference in FLACC behavioral score between the two groups on admission ( P>0.05). The FLACC behavioral score was (4.0±0.7)points,(3.4±0.6)points and (2.4±0.6)points in family empowerment group at days 1, 3 and 7 after skin traction, lower than (4.8±0.7)points, (3.9±0.8)points and (3.3±0.5)points in routine nursing groups (all Ρ<0.01). One month after skin traction, treatment compliance was excellent in 51 patients, good in 4, poor in 0, with treatment compliance rate of 92.7% (51/55) in family empowerment group, and was excellent in 40 patients, good in 9, poor in 3, with treatment compliance rate of 76.9% (40/52) in routine nursing group ( Ρ<0.05). The complication rate was 5.4% (3/55) in family empowerment group, lower than 21.2% (11/52) in routine nursing group ( Ρ<0.05). The length of hospital stay and fracture healing time were (15.6±0.3)days and (7.1±0.8)weeks in family empowerment group, shorter than (16.8±0.3)days and (8.2±0.4)weeks in routine nursing group (all Ρ<0.01). Conclusion:For children with femoral shaft fractures treated by skin traction, nursing using FCEM can alleviate pain, improve treatment compliance, reduce complication rate, reduce hospital stay and shorten fracture healing time.

Objective To analyze the topological characteristics of the brain structural network in primary angle-closure glaucoma (PACG) patients by applying graph theoretical approaches.Methods From October 2015 to April 2017, nineteen PACG patients and nineteen gender-and age-matched healthy controls (HCs) were enrolled to undergo MRI scan. The whole brain was parceled into 90 regions by automated anatomical labeling template, and the brain structural network was constructed by the fiber distribution of continuous tracking method.Both the weighted and unweighted network analyses were performed.The global and regional properties were computed by graph theoretical analysis.To compare the brain network regional properties between two groups, two-sample t-test was utilized.The correlations between the brain structural network properties and clinical parameters were further analysed. Results Both two groups were found to follow the efficient small-world characteristics. Compared to HCs, the brain structural network in PACG patients showed no statistical significance in the small-worldness, average shortest path, clustering coefficient, global efficiency and local efficiency(P＞0.05). Compared to the HCs, the PACG patients showed decreased nodal efficiency in the right superior frontal gyrus, right inferior frontal gyrus, left median cingulate and paracingulate gyri, left amygdala and left cuneus(P＜0.05). Compared to HCs, the PACG patients showed decreased node degree in left superior frontal gyrus, medial orbital, right inferior frontal gyrus, left amygdala, left cuneus and left lingual gyrus(P＜0.05). Compared with the hub regions in healthy controls'network, we found that two hub regions disappeared.Those hubs were right inferior parietal lobule and left middle temporal gyrus. Node degree in left amygdala showed negatively correlated with visual ability (r=-0.679, P=0.001). Node degree in left lingual gyrus showed negatively correlated with vertical CDR(r=-0.791, P=0.001),which showed positively correlated with visual acuity(r=0.538, P=0.018).Conclusions The brain structural network in PACG patients showed small-worldness properties as HCs group. The alterations of local properties in visual, emotion-cognition brain regions were observed, manifesting that PACG can affect the topology properties of the structural brain network.
