Objective:To compare the efficacy and safety of crisaborole ointment 2% versus pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged 2 years or older.Methods:A multicenter, randomized, open-label, controlled clinical trial was conducted. A total of 120 pediatric patients aged 2 - 17 years with mild to moderate atopic dermatitis were enrolled from departments of dermatology of 8 hospitals in China between March 2022 and February 2023. The participants were randomly assigned in a 1∶1 ratio to the crisaborole group and the pimecrolimus group, and received the treatment with crisaborole ointment 2% and pimecrolimus cream 1% respectively, twice a day for 4 weeks. Visits were scheduled at baseline/on day 1, as well as on days 8, 15, and 29. The primary efficacy outcome was the percentage of patients achieving the Investigator's Static Global Assessment (ISGA) success (defined as clear [0] or almost clear [1] on the ISGA scale, combined with ≥ 2‐grade improvement from baseline) on day 29. The secondary efficacy outcomes included changes in the Eczema Area and Severity Index (EASI) total scores from baseline to day 29, percentages of patients achieving ISGA improvement (defined as clear [0] or almost clear [1] on the ISGA scale), as well as changes in the Peak Pruritus Numerical Rating Scale (NRS) scores, Dermatology Life Quality Index (DLQI) /Infants' Dermatology Life Quality Index (IDLQI) /Children's Dermatology Life Quality Index (CDLQI) scores, and in the Dermatitis Family Impact (DFI) scores. Drug safety was evaluated according to the incidence of adverse events. Categorical data were compared using the chi-square test. Since measurement data did not follow a normal distribution, the rank sum test was used for comparisons of measurement data between groups.Results:A total of 106 children with mild to moderate atopic dermatitis were included in the per-protocol analysis set, with 52 in the crisaborole group (26 males and 26 females) and 54 in the pimecrolimus group (27 males and 27 females). There were no significant differences in age, disease duration, ISGA and EASI scores at baseline between the two groups (all P > 0.05). On day 29, 22 patients (42.31%) in the crisaborole group and 25 (46.30%) in the pimecrolimus group achieved ISGA success, with no significant difference between the two groups ( χ2 = 0.17, P = 0.68) ; 35 patients (67.31%) in the crisaborole group and 45 (83.33%) in the pimecrolimus group achieved ISGA improvement, also with no significant difference between the two groups ( χ2 = 3.68, P = 0.06) ; additionally, there were no significant differences in the EASI, pruritus NRS, DLQI/IDLQI/CDLQI, or DFI scores between the two groups (all P > 0.05). Adverse reactions to the two topical agents were mainly local reactions such as mild to moderate pain, itching, or worsening of itching, and no obvious systemic adverse reactions occurred. The incidence of drug-related adverse reactions was 46.15% (24 cases) in the crisaborole group and 37.04% (20 cases) in the pimecrolimus group, with no significant difference between the two groups ( χ2 = 0.91, P = 0.34) . Conclusion:The efficacy of crisaborole ointment 2% was comparable to that of pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged ≥ 2 years, and it yielded early and rapid improvement in the quality of life of patients and their families, with good safety and tolerability profiles.

The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital.

Objective To investigate the population composition,seasonal dynamics,and infestation levels of cockroaches in Lanzhou,China,and to provide information for the scientific development of cockroach control strategies.Methods Monitoring was conducted at three locations using the sticky trap method.Habitats included farm product markets,catering establishments,hotels,hospitals,and residential areas.Results From 2016 to 2023,the average cockroach density was 0.77 insects per board,with an average infestation rate of 10.84%.Blattella germanica was the dominant species.Seasonal density of cockroaches showed an approximately unimodal distribution,peaking in September.The highest average density and infestation rates were observed in farm product markets.Conclusions Cockroach density and infestation levels in Lanzhou remained relatively low.A comprehensive prevention and control strategy focusing on environmental management in key areas should be implemented according to the seasonal fluctuations.

Objective To investigate the effect of remimazolam(Rem)on retinal ischemia-reper-fusion injury(RIRI)in rats and its regulatory mechanism on the high-mobility group box 1(HMGB1)/receptor for advanced glycation end products(RAGE)/nuclear factor-κB(NF-κB)signaling pathway.Methods Rats were randomly divided into Sham group,Model group,Rem-L group(low-dose Rem),Rem-M group(medium-dose Rem),Rem-H group(high-dose Rem),and high-dose Rem plus HMGB1 activator dexamethasone(DEX)group(Rem-H+DEX group),with 15 rats in each group.Except for the Sham group,RIRI model was established in the other groups by increasing in-traocular pressure.Hematoxylin and eosin(HE)staining was used to observe the changes in retinal tissue structure in each group.The TUNEL method was used to detect retinal tissue apoptosis.En-zyme-linked immunosorbent assay(ELISA)was performed to detect the expression levels of interleu-kin-1β(IL-1β),tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6)in the serum of rats in each group.Kits were used to detect the levels of oxidative stress indicators,including superoxide dis-mutase(SOD),glutathione peroxidase(GSH-PX),and malondialdehyde(MDA).Western blot was used to detect the expression levels of hypoxia-related factors[hypoxia-inducible factor-1α(HIF-1α),vascular endothelial growth factor(VEGF)]and HMGB1/RAGE/NF-κB signaling pathway-related proteins in retinal tissue.Results Compared with the Sham group,the Model group showed severe retinal edema,a significant decrease in the number of ganglion cells,vacuolar changes in cells with disordered arrangement,and widened cell gaps.With increasing doses of Rem,the degree of retinal edema gradually decreased,the number of ganglion cells increased,and their arrangement became more orderly in RIRI rats.Compared with the Sham group,the Model group exhibited increased ret-inal cell apoptosis rate,serum levels of IL-1 β,IL-6,and TNF-α and increased expression levels of MDA,HMGB1,RAGE,NF-κB,HIF-1α and VEGF in retinal tissue,while the expression levels of SOD and GSH-PX decreased(P＜0.05).Compared with the Model group,the Rem-L,Rem-M,and Rem-H groups showed dose-dependent decreases in retinal cell apoptosis rate,serum levels of IL-1 β,IL-6,and TNF-α,and expression levels of MDA,HMGB1,RAGE,NF-κB,HIF-1α and VEGF in retinal tissue,with dose-dependent increases in the expression levels of SOD and GSH-PX(P＜0.05).Compared with the Rem-H group,the Rem-H+DEX group showed reversed trends in the above indicators.Conclusion Rem can inhibit the occurrence of RIRI in rats,and its mecha-nism of action may be related to the regulation of the HMGB1/RAGE/NF-κB signaling pathway.

Function-preserving surgery for gastric cancer is a treatment strategy aimed at improving postoperative function while ensuring oncological safety. By preserving important anatomical structures such as the cardia, pylorus, and vagus nerve, as well as key functions like digestion, secretion, emptying, and anti-reflux, this approach aims to minimize the negative impact on patients' postoperative quality of life. With the widespread application of neoadjuvant treatment and the continuous improvement in the efficacy of anti-tumor drugs, the application and indications for functional-preserving surgery may further expand. This article reviews the current status and future prospects of function-preserving surgery for gastric cancer, focusing on its main types, applications after neoadjuvant therapy, and the exploration of new technologies.

Aim To investigate the effects of total fla-vonoids of Chuzhou chrysanthemum(TFCC)on the activity and migration of rat brain artery endothelial cells under hypoxia/reoxygenation(H/R)injury,as well as the relationship between TFCC's effects and vascular endothelial growth factor receptor 2(VEGFR2).Methods Primary rat brain artery endo-thelial cells were cultured,the H/R model of cells was constructed,VEGFR2 inhibitor SU5416(10 μmol·L-1)was used and a cell transfection model was estab-lished.The cell activity was detected by CCK-8,and the cell migration was detected by scratch method and Transwell assay.Results TFCC(30,90,270 mg·L-1)significantly increased the activity and migration ability of rat brain artery endothelial cells with H/R in-jury,the use of VEGFR2 blocker SU5416 and transfec-tion of VEGFR2 siRNA could significantly inhibit the enhanced activity and migration ability of TFCC on cer-ebral vascular endothelial cells in rats with H/R inju-ry.Conclusions TFCC promotes the activity and mi-gration ability of rat brain artery endothelial cell with H/R injury,and its mechanism is related to VEGFR2.

Objective:To analyze the carriage status, subtype distribution and flanking gene sequence characteristics of oxacillinases (OXA enzyme) in 241 clinical strains of Pseudomonas aeruginosa, and assess their roles in the drug resistance of Pseudomonas aeruginosa and ability to horizontally transfer across species. Methods:Clinical P. aeruginosa isolates were collected from four hospitals in Sanya, Tangshan, Zhangjiakou, and Beijing. The prevalence of oxacillinases and their flanking gene sequences was analyzed by whole-genome sequencing (NGS) and bioinformatic approaches. Results:A total of 241 isolates of P. aeruginosa were gathered, and 35 blaOXA subtypes were identified through screening of 252 blaOXA genes. These genes were classified into three subfamilies: blaOXA-50-like (241, 95.6%), blaOXA-1-like (9, 3.6%) and blaOXA-10-like (2, 0.8%). Among these, 11 subtypes (11, 31.4%) were novel blaOXA subtypes. Nine of these belonged to the blaOXA-50-like subfamily and were designated as blaOXA-1244, blaOXA-1245, blaOXA-1246, blaOXA-1250, blaOXA-1252, blaOXA-1253, blaOXA-1254, blaOXA-1255, and blaOXA-1256. The remaining two belonged to the blaOXA-10-like subfamily and were named blaOXA-1247 and blaOXA-1248. Compared to the amino acid sequence of OXA-10, the newly identified subtype OXA-1247 exhibited a mutation at position 117, where a valine was replaced by a leucine. This change was thought to improve the enzyme′s ability to hydrolyze carbapenems. In the analysis of the flanking sequences of the blaOXA genes, Class I integrons were identified in four bacterial strains. The variable regions of these integrons carried three distinct patterns of resistance gene cassettes: aac( 6′) -Ib-blaOXA-1247-ant( 3′′) -Ia, aac( 6′) -Ib-blaOXA-1248 and aac( 6′) -Ib- blaIMP-45-blaOXA-1-catB3. Among these, the strain BJ2326 carried a class I integron that was connected to the downstream IS CR1 element to form a composite class I integron structure, additionally carrying the resistance gene blaPER-1. Out of the 223 non-wild-type P. aeruginosa strains, 127 strains exhibited non-wild-type profiles to the four beta-lactam antibiotics MEM, CAZ, FEP, and TZP, with the combination of MEM+CAZ+FEP being the most prevalent, representing 57.0% of the total. Conclusions:The blaOXA genes in 241 clinical P. aeruginosa strains showed diversity. Some blaOXA genes had a co-transfer risk with the metallo-β-lactamase resistance gene blaIMP-45. Among the 11 newly discovered blaOXA subtypes, the new subtype OXA-1247 may have carbapenemase activity and potential for horizontal transfer.
