Objective To investigate the expression and significance of heat shock protein 70(HSP70),apoptosis-associated speck-like protein(ASC),and vitamin D in children with febrile seizures(FS).Methods A total of 200 children with FS admitted to our hospital from June 2022 to December 2023 were selected as FS group,including 158 cases of simple FS and 42 cases of complex FS.Another 200 febrile children without FS were selected as fever group,and 50 healthy children were selected as control group.The differences in HSP70,ASC mRNA,and vitamin D expression a-mong the three groups were compared.The differences in HSP70,ASC mRNA,and vitamin D ex-pression at different time points in children with different types of FS were compared.The influencing factors and predictive value of complex FS were analyzed.Results At admission,the expression lev-els of HSP70 and ASC mRNA gradually decreased,while the vitamin D levels gradually increased in the FS group,fever group,and control group,with statistically significant between-group differences(P＜0.01).One hour after admission,the levels of HSP70 and ASC mRNA in both the complex FS group and the simple FS group were lower than those at admission(P＜0.01).The levels of HSP70 and ASC mRNA in the complex FS group at admission and 1 hour after admission were higher than those in the simple FS group,while the vitamin D level was lower(P＜0.01).Multivariate Logistic regression analysis showed that elevated HSP70 and ASC mRNA levels at admission were independ-ent risk factors for complex FS(P＜0.001),while elevated vitamin D level was an independent protective factor for complex FS(P＜0.001).The area under the curve(AUC)for HSP70,ASC mRNA,and vitamin D in assessing complex FS were 0.785(95％CI,0.721 to 0.840),0.766(95％CI,0.701 to 0.823),and0.760(95％CI,0.695 to 0.817),respectively.The combined AUC of HSP70,ASC mRNA,and vitamin D for assessing complex FS was 0.915,with a sensitivity of 90.48％and a specificity of 81.65％.The AUC of combined assessment of complex FS by vari-ous factors was greater than that of HSP70,ASC mRNA,and vitamin D alone(Z=2.743,2.749,3.086,P=0.006,0.006,0.002).Conclusion The levels of HSP70 and ASC mRNA are elevat-ed,while the vitamin D level is reduced in children with complex and simple FS.The combined as-sessment of HSP70,ASC mRNA,and vitamin D at admission has high value in assessing complex FS.

Objective To explore the effect of dexmedetomidine on the proliferation,invasion and cell cycle of gallbladder cancer cells by regulating the C-C chemokine ligand 2(CCL2)-C-C chemokine receptor 2(CCR2)pathway.Methods GBC-SD cells were devided into the control group,the low concentration dexmedetomidine group(2 μmol/L),the high concentration dexmedetomidine group(4 μmol/L)and the high concentration dexmedetomidine+CCL2 group(4 μmol/L dexmedetomidine and 10 μg/L CCL2 protein).The clone formation experiment and Edu experiment were performed to measure cell proliferation.Transwell experiment was performed to measure cell invasion and migration.Flow cytometry was performed to measure cell cycle and apoptosis.Western blot assay was used to measure the proliferating cell nuclear antigen(PCNA),Cyclin D1,matrix metalloproteinase(MMP)-2,MMP-9,Bcl-2 associated X protein(Bax),cysteine-dependent aspartate-specific protease-3(Caspase-3),CCL2 and CCR2 proteins.The nude mouse transplant tumor experiment was used to determine the growth of gallbladder cancer transplant tumors.Results After treatment with low and high concentrations of dexmedetomidine,the number of cell clone formed,the positive rate of Edu,the numbers of invasions and migrations,the expression levels of PCNA,CyclinD1,MMP-2,MMP-9,CCL2 and CCR2 proteins,the proportions of G2/M and S phase cells decreased,the proportion of G0/G1 phase cells,apoptosis rate and expression levels of Bax and Caspase-3 proteins increased,and the effect of high-concentration dexmedetomidine was more significant(P＜0.05).The inhibitory effects of dexmedetomidine on the proliferation,invasion,migration and cell cycle of gallbladder cancer cells,as well as its promoting effect on cell apoptosis could be reversed by CCL2 protein(P＜0.05).In vivo experiments showed that dexmedetomidine could reduce tumor mass,tumor volume of nude mice and expression levels of CCL2 and CCR2 proteins(P＜0.05).Conclusion Dexmedetomidine inhibits the proliferation and invasion of gallbladder cancer cells,and blocks the cell cycle in the G0/G1 phase by suppressing the CCL2-CCR2 pathway.

Objective To investigate the reliability and validity of the assessment tools of Brief ICF Core Sets for Arthroplasty of Knee Osteoarthritis in Perioperative Period(ICSAKOPP). Methods From May,2022 to April,2023,320 patients undergoing knee arthroplasty were selected in Peking University Third Hospital,China-Japan Friendship Hospital,Peking University First Hospital and Chinese PLA General Hospital.Trained assessors used Brief ICSAKOPP to evaluate all enrolled patients before arthroplasty,three days(±one day)after arthroplasty,three weeks(±one week)after arthroplasty,and three months(±one month)after ar-throplasty.Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)scores were recorded at the same time.Five professionals were asked to score all the items of Brief ICSAKOPP,and the content validity index(CVI)was caculated. Results A total of 64 cases were dropped down.CVI of all the items of the Brief ICSAKOPP were above 0.8,with a av-erage CVI of the scale of 0.938.The Cronbach's α coefficient of the Brief ICSAKOPP was 0.813.There was a moderate correlation(r=0.681,P<0.001)between the overall Brief ICSAKOPP and WOMAC scores,as well as body functional dimension score(r=0.668,P<0.001)and activities and participation dimension score(r=0.657,P<0.001). Conclusion Brief ICSAKOPP is good in content validity,internal consistency reliability and criterion validity.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Objective To investigate the effect of sufentanil(ST)on lipopolysaccharide-induced acute lung injury(ALI)in rats by regulating the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)/stimulator of interferon gene(STING)signaling pathway.Methods Male SD rats were induced by lipopolysaccharide to construct an ALI model.The successfully modeled rats were randomly separated into ALI group,L-ST group,H-ST group,and H-ST+DMXAA group,with 6 rats in each group.Among them,the L-ST group and H-ST group were intraperitoneally injected with 2.5 μg/ml and 5 μg/ml ST after successful modeling immediately.The H-ST+DMXAA group was given 25 mg/kg DMXAA by gavage on the basis of intraperitoneal injection of 5 μg/ml ST.Six healthy and normal temperature rats were randomly selected as the control group,and an equal amount of physiological saline was injected intraperitoneally.The reagent kit was used to detect the SOD enzyme activity and MDA content in serum;ELISA was used to detect the levels of inflammatory factors such as interleukin-10(IL-10),tumor necrosis factor-α(TNF-α),and IL-6 in bronchoalveolar lavage fluid(BALF);cell staining was used to detect the total number of cells and neutrophils in BALF;the wet to dry mass ratio of lung tissue was calculated;HE staining was used to observe pathological changes in lung tissue,while Western blot was applied to detect the expression of cGAS and STING proteins in lung tissue.Results After L-ST and H-ST treatment,the SOD enzyme activity and IL-10 level increased sequentially,the MDA,TNF-α,IL-6,W/D value,total number of cells and neutrophils,cGAS,and STING protein expression decreased sequentially(P<0.05),while lung tissue injury was effectively alleviated.DMXAA reversed the influence of H-ST on the above indexes(P<0.05).Conclusion ST may inhibit the cGAS-STING pathway,reduce inflammation and oxidative stress responses,and thereby alleviates lipopolysaccharide induced ALI in rats.

ObjectiveTo investigate the pharmacological effect and metabolic mechanism of Linderae Radix on the intrauterine adhesion （IUA） rat model. MethodAn IUA rat model was induced by mechanical injury and infection. Molecular biology and pharmacology techniques were employed to evaluate the inhibitory effect of Linderae Radix extract （LAE） on fibrosis in IUA. Serum metabolomics analysis based on gas chromatography-mass spectrometry （GC-MS） was conducted to explore the metabolic regulation mechanism of LAE. ResultAnimal experiments showed that LAE significantly improved the morphology and structural damage of uterine tissue cells in the IUA rat model， promoted endometrial proliferation， vascular regeneration， and morphological recovery， inhibited the mRNA expression of transforming growth factor-β₁ （TGF-β₁）， Smad2， and Smad3， and increased the expression of Smad7 mRNA to suppress fibrosis. Additionally， LAE significantly suppressed the levels of estrogen （E₂）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and tumor necrosis factor-α （TNF-α） expression （P<0.01）， thereby improving the uterine microenvironment. Metabolomics analysis revealed significant metabolic abnormalities in the serum of IUA rats compared with the results in the normal group， and nine differential metabolites were identified. LAE effectively ameliorated these metabolic abnormalities， primarily by influencing six differential metabolites， including five shared metabolites among the nine identified markers： L-aspartic acid， L-pyroglutamic acid， L-serine， glucose， and L-norvaline. Pathway enrichment analysis indicated that the aminoacyl-tRNA biosynthesis pathway was the main affecting mechanism. ConclusionIn combination with the pharmacological research results， LAE effectively improved uterine damage and inhibited fibrosis in the IUA rat model. Its mechanism may involve the inhibition of the aminoacyl-tRNA biosynthesis pathway and the improvement of the microenvironment.
