To evaluate the therapeutic effect of baicalein topical preparation on atopic dermatitis, we first constructed two atopic dermatitis-like mouse models induced by calcipotriol and 1-fluoro-2,4-dinitrobenzene to assess their therapeutic effect with skin tissue staining and other experiments. It was found that topical preparation of baicalein could alleviate epidermal thickening of diseased skin tissues, repair damaged skin barrier proteins, and inhibit T helper 2 cells (Th2) infiltration and mast cell infiltration and activation in lesional sites. Cyberpharmacology was utilized to analyze whether baicalein could treat atopic dermatitis by interfering with multiple pathogenesis-associated pathways. Results indicated that baicalein reduced the mRNA levels of inflammatory factors and inhibited the phosphorylation of NF-κB p65 and STAT1 proteins in keratinocyte cells. Together, the topical preparation of baicalein may be effective in alleviating atopic dermatitis-like symptoms in mice by down-regulating the phosphorylation level of NF-κB in keratinocytes, thereby decreasing the expression of inflammatory factors in keratinocytes, which provides an idea and a theoretical basis for the topical preparation of baicalein for the treatment of inflammatory skin diseases such as atopic dermatitis.

Objective: To analyze the characteristics of alcohol poisoning cases among minors receiving pre hospital 120 emergency services in Zhengzhou, providing evidence for regional management strategies of alcohol poisoning among minors. Methods: A retrospective study was conducted on 1 630 alcohol poisoning cases (aged 0-18 years) from Zhengzhou s 120 emergency system during 2017-2019 and 2023. Data on gender, age, occurrence timeframes were analyzed using t-test and χ 2 test for intergroup comparisons. Results: Annual cases were 291 (2017), 353 (2018), 483 (2019), and 503 (2023). Compared with 2017, male alcohol poisoning cases increased by 66.94% while female cases surged 104.35% by 2023. The peak incidence of alcohol poisoning among minors occurred among 16-18 year olds (85.40%), followed by 13-15 year olds (13.74%). Most cases clustered between 21:01-03:00 (60.43%), with male cases peaking at 22:01-23:00 (12.73%) and female cases peaking at 02:01-03:00 ( 11.25 %). Between 00:01-03:00, male cases progressively decreased while female cases increased. Severity distribution showed 355 mild cases (21.78%), 1 035 moderate cases (63.50%), and 240 severe cases (14.72%). Conclusions Zhengzhou region has experienced sustained growth in underage alcohol poisoning cases, predominantly occurring from evening to early morning with moderate severity, female cases demonstrate faster growth rates. Multifaceted regulatory measures should be implemented to strengthen supervision of underage drinking behaviors.

Oroxylin A (OA) is a natural flavonoid primarily derived from the plants Oroxylum indicum and Scutellaria baicalensis. Currently, OA is obtainable through chemical synthesis and exhibits polypharmacological properties, including anti-cancer, anti-inflammatory, anti-microbial, and multi-organ protective effects. The first-in-class drug OA tablets are presently undergoing phase Ib/IIa clinical trials for hepatocellular carcinoma (HCC) treatment. Substantial evidence suggests that OA demonstrates therapeutic potential against various hepatic and gastrointestinal (GI) disorders, including HCC, hepatic fibrosis, fatty liver disease, hepatitis, liver injury, colitis, and colorectal cancer (CRC). OA exerts its therapeutic effects primarily by modulating several crucial signaling pathways, including those associated with apoptosis, oxidative stress, inflammation, glucolipid metabolism, and fibrosis activation. The oral pharmacokinetics of OA is characterized by phase II metabolism, hydrolysis, and enterohepatic recycling. This review provides a comprehensive overview of the critical stages involved in the development of OA tablets, presenting a holistic perspective on the progression of this first-in-class drug from preclinical to clinical phases. It encompasses the synthesis of active pharmaceutical ingredients, pharmacokinetics, pharmacological efficacy, toxicology, drug delivery, and recent advancements in clinical trials. Importantly, this review examines the potential mechanisms by which OA may influence the gut-liver axis, hypothesizing that these interactions may confer health benefits associated with OA that transcend the limitations posed by its poor bioavailability.

Objective To investigate the changes of residual radioactivity at different time points after 131I treatment in the patients with differentiated thyroid cancer(DTC)and influencing factors.Methods A to-tal of 235 patients with DTC receiving 131I treatment in this hospital from January 2021 to June 2023 were se-lected as the study subjects and divided into the high dose group(＞5.55 GBp,n=56)and low dose group(≤5.55 GBp,n=179)according to the treatment dose.The clinical data of the two groups were collected and the changes of residual radioactivity after 131I treatment were compared between the two groups.The binary re-gression was used to analyze its influencing factors.Results The sex,age,BMI,basic metabolic rate(BMR)and serum thyroglobulin antibody(TgAb)had no statistical differences between the two groups(P＞0.05).The proportions of serum thyroglobulin(TG)＜1 ng/mL,131I first time treatment and residual thyroid ratio prompted by the whole body 131I scan after treatment in the low dose group were significantly higher than those in the high dose group(P＜0.05).The residual radioactivity in the two groups was significantly de-creased with time extension.The residual radioactivity at 24,48,72 h after treatment in the low dose group was significantly lower than that in the high dose group(P＜0.05).The binary logistic regression analysis re-sults showed that the T stage and treatment dose were the influencing factors of residual radioactivity after 131I treatment.Conclusion The residual radioactivity after 131I treatment in the patients with DTC shows the significant decreasing trend with time extension,this change trend has an active significance for further opti-mizing and perfecting the isolation and protection scheme.For the patients with high T stage and big treat-ment dose,the isolation time should exceed 72 h.

Objective To explore the diagnostic value of ultrasound imaging parameters combined with ser-um progranulin(PGRN)and programmed cell death ligand 1(PD-L1)for lymph node metastasis of non-small cell lung cancer(NSCLC).Methods A total of 135 NSCLC patients admitted to Hengshui Cardiovascu-lar Hospital from February 2022 to May 2024 were selected as the NSCLC group.According to whether lymph node metastasis occurred,the NSCLC patients were divided into the metastasis group(52 cases)and the non-metastasis group(83 cases).Another 135 patients with benign lung diseases who were admitted to the hospi-tal during the same period were selected as the control group.The levels of serum PGRN and PD-L1 were de-tected by enzyme-linked immunosorbent assay.Multivariate Logistic regression analysis was conducted to ana-lyze the factors influencing lymph node metastasis of NSCLC.The receiver operating characteristic curve was used to analyze the diagnostic value of ultrasound imaging parameters[end-diastolic velocity(EDV),peak systolic velocity(PSV),and minimum axial diameter(MAD)]combined with serum levels of PGRN and PD-L1 for lymph node metastasis of NSCLC.Results Compared with the control group,the levels of serum PGRN and PD-L1 in the NSCLC group were significantly increased,and the difference was statistically signifi-cant(P<0.05).Compared with the non-metastasis group,the levels of serum PGRN and PD-L1 in the metas-tasis group were significantly increased,and the difference was statistically significant(P<0.05).Compared with the non-metastasis group,the ultrasound imaging parameters EDV,PSV and MAD in the metastasis group were significantly increased,and the difference was statistically significant(P<0.05).The results of multivariate Logistic regression analysis showed that PGRN,PD-L1,EDV,PSV,and MAD were all independ-ent risk factors affecting lymph node metastasis of NSCLC(P<0.05).The area under the curve(AUC)of serum PGRN,PD-L1 and ultrasound imaging parameters EDV,PSV and MAD for the diagnosis of lymph node metastasis of NSCLC separately was 0.805,0.792,0.745,0.738 and 0.737,respectively.The AUC of com-bined diagnosis for lymph node metastasis of NSCLC was 0.938,which was superior to that of single diagnosis(ZPGRN-combination=3.424,ZPD-L1-combination=4.076,ZEDV-combination=3.891,ZPSV-combination=4.755,ZMAD-combination=4.400,P<0.05).Conclusion Ultrasound imaging parameters combined with serum PGRN and PD-L1 have certain diagnostic value for lymph node metastasis of NSCLC.

Objective To analyze the effects of tactile vibration feedback training combined with 1 Hz repetitive tran-scranial magnetic stimulation on limb balance and walking ability of stroke patients with hemiplegia.Methods From August 2021 to August 2023,98 patients with stroke and hemiplegia who were diagnosed and treated in Daxing District People's Hospital were selected and divided into training group and stimulation group according to different treatment schemes with 49 in each.The training group was given tactile vibration feedback training,and the stimula-tion group was given tactile vibration feedback training combined with 1 Hz repetitive trans-cranial magnetic stimula-tion.The clinical symptoms,ability of keeping balance and walk,life situation and curative effect of the two groups were analyzed.Results After 8 weeks of treatment,the scores of mouth and drooling points,language impairment points,and hemiparalysis points in the two groups were all lower than those before treatment(P<0.05),and the above indexes in the stimulation group were even lower than those in the training group(P<0.05).After 8 weeks of treatment,the scores of Lindmark Balance Reaction,Berg Balance scale(BBS),stride length,10-meters maximum walking speed(10 mMWS),Barthel index(BI)and Functional Independence Measure(FIM)in both groups were higher than those before treatment(P<0.05),and the above indexes in the stimulation group were higher than those in the training group(P<0.05).After 8 weeks of treatment,the total effective rate in the stimulation group(91.84％)was higher than that in the training group(69.39％)(P<0.05).Conclusions Tactile vibration feedback training plus 1 Hz repetitive trans-cranial magnetic stimulation can significantly alleviate the clinical symptoms of stroke patients with hemiplegia and can improve their ability of keeping balance,walking and management of daily life.

Animal experiment is a key link in the scientific research of traditional Chinese medicine,and the syndrome animal model is an important research object in the animal experiment of traditional Chinese medicine.Good reproducibility,repeatability,specificity,safety,convenience and economy are the basic requirements of animal model.In recent years,with the continuous development of animal experimental studies on lung diseases,the animal model construction and evaluation methods of related syndromes have been improved to a certain extent.However,in terms of model evaluation,problems such as more subjective descriptions,less accurate quantification,more macro representations,less microscopic evidence,more disease-related indicators,less syndrome-related indicators,and lack of primary and secondary stratification of indicators continue to be prominent.Therefore,based on the literature review method,the author systematically reviewed the current research progress of lung disease syndrome models,and proposed that strengthening the research on the four-diagnosis manifestations and reaction characteristics of model animals,standardization of modeling interventions,four-diagnosis information collection tool and the objective evaluation study,and the TCM syndrome model evaluation scale study might be feasible approaches for future model optimization.In order to provide new ideas and methods for the study of the syndrome model of lung disease in the future.

The aging disease associated with type 2 diabetes mellitus(T2DM)is a hot research topic in the field of diabetes at present.Sarcopenia has become the third major complication of T2DM after microvascular and macrovascular diseases,which could lead to the occurrence and development of various adverse events such as fracture,disability,and dysfunction.The spleen belongs to the earth,is in the middle jiao,governs transportation and transformation,and governs muscle.The functional activities of the spleen manifesting in normal transformation and transportation,the distribution of cereal essence,and the nourishment of muscles are necessary for normal physiological functions to be exerted.Recent studies have shown that skeletal muscle cell ferroptosis plays an important role in the pathogenesis of T2DM sarcopenia.Based on the theory of"spleen governing transportation and transportation and governing muscle",this study explores the pathogenesis of T2DM sarcopenia from the perspectives of the pathogenesis of"dysfunction of spleen in transportation,deficiency of cereal essence,obstruction of dampness and turbidity,and muscle dystrophy"in traditional Chinese medicine and the pathological mechanism of"skeletal muscle cell ferroptosis"in modern medicine.It summarizes the principles of traditional Chinese medicine prevention and treatment for T2DM sarcopenia based on the spleen,to provide theoretical support for enriching the theoretical connotation of spleen visceral state,as well as basic research and clinical trials on the prevention and treatment of T2DM sarcopenia with traditional Chinese medicine.

Objective:To evaluate the role of minimal residual disease (MRD) monitoring during early induction therapy for the treatment of childhood acute lymphoblastic leukemia (ALL).Methods:This was a multicenter retrospective cohort study. Clinical data of 1 164 ALL patients first diagnosed between October 2016 and June 2019 was collected from 16 hospitals in South China Children′s Leukemia Group. According to MRD assay on day 15 of early induction therapy, they were divided into MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group. According to MRD assay on day 33, they were divided into MRD<0.01% group, MRD 0.01%-<1.00% group and MRD≥1.00% group. Age, onset white blood cell count, central nervous system leukemia (CNSL), molecular genetic characteristics and other data were compared between groups. Kaplan-Meier method was used for survival analysis. Cox regression model was used to analyze prognostic factors.Results:Of the 1 164 enrolled patients, there were 692 males and 472 females. The age of diagnosis was 4.7 (0.5, 17.4) years. The white blood cell count at initial diagnosis was 10.7 (0.4, 1 409.0) ×10 9/L. Among all patients, 53 cases (4.6%) had CNSL. The follow-up time was 47.6 (0.5, 68.8) months. The 5-year overall survival (OS) and 5-year relapse-free survival (RFS) rates were (93.1±0.8) % and (90.3±1.1) %. On day 15 of early induction therapy, there were 466 cases in the MRD<0.10% group, 523 cases in the MRD 0.10%-<10.00% group and 175 cases in the MRD≥10.00% group. The 5-year OS rates of the MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group were (95.4±1.0) %, (93.3±1.1) %, (85.4±2.9) %, respectively, while the RFS rates were (93.2±1.6) %, (90.8±1.4) %, (78.9±4.3) %, respectively ( χ2=16.47, 21.06, both P<0.05). On day 33 of early induction therapy, there were 925 cases in the MRD <0.01% group, 164 cases in the MRD 0.01%-<1.00% group and 59 cases in the MRD≥1.00% group. The 5-year RFS rates in the MRD 0.01%-<1.00% group was lowest among three groups ((91.4±1.2) % vs. (84.5±3.2) % vs. (87.9±5.1) %). The difference between three groups is statistically significant ( χ2=9.11, P=0.010). Among ALL patients with MRD≥10.00% on day 15 of induction therapy, there were 80 cases in the MRD <0.01% group on day 33, 45 cases in the MRD 0.01%-<1.00% group on day 33 and 45 cases in the MRD≥1.00% group on day 33. The 5-year RFS rates of three groups were (83.9±6.0)%, (67.1±8.2)%, (83.3±6.9)% respectively ( χ2=6.90, P=0.032). Univariate analysis was performed in the MRD≥10.00% group on day 15 and the MRD 0.01%-<1.00% group on day 33.The 5-year RFS rate of children with CNSL was significantly lower than that without CNSL in the MRD≥10.00% group on day 15 ((50.0±20.4)% vs. (80.3±4.4)%, χ2=4.13, P=0.042). Patients with CNSL or MLL gene rearrangement in the MRD 0.01%-<1.00% group on day 33 had significant lower 5-year RFS rate compared to those without CNSL or MLL gene rearrangement ((50.0±25.0)% vs. (85.5±3.1)%, χ2=4.06, P=0.044;(58.3±18.6)% vs. (85.7±3.2)%, χ2=9.44, P=0.002). Multivariate analysis showed that age ( OR=0.58, 95% CI 0.35-0.97) and white blood cell count at first diagnosis ( OR=0.43, 95% CI 0.27-0.70) were independent risk factors for OS. The MRD level on day 15 ( OR=0.55,95% CI 0.31-0.97), ETV6-RUNX1 fusion gene ( OR=0.13,95% CI 0.03-0.54), MLL gene rearrangement ( OR=2.55,95% CI 1.18-5.53) and white blood cell count at initial diagnosis ( OR=0.52,95% CI 0.33-0.81) were independent prognostic factors for RFS. Conclusions:The higher the level of MRD in early induction therapy, the worse the OS. The MRD levels on day 15 is an independent prognostic factor for RFS.The MRD in early induction therapy guided accurate risk stratification and individualized treatment can improve the survival rate of pediatric ALL.

Objective:To compare the effects of unilateral thoracic paravertebal block with lidocaine on hemodynamic and the level of consciousness during double lumen endotracheal intubation.Methods:From June to october 2021,a total of 40 patients American Society of Anesthesiologists(ASA)physical status Ⅰ-Ⅱ,aged 19-65 years,scheduled for elective thoracic sugeries in Peking University Interna-tional Hospital block with under general anesthesia requiring orotracheal intubation were recruited and di-vided into two groups:The double-lumen endobronchial intubation(group C)and double-lumen endo-bronchial intubation after thoracic paravertebal block with lidocaine(group P).After an intravenous an-esthetic induction,the orotracheal double-lumen intubation was performed using a Macintosh direct laryn-goscopy,respectively.Invasive blood pressure(BP)and heart rate(HR)were recorded before and after anesthetic induction,immediately after intubation and 5 min after intubation with 1-minute interval and the intubation time was also noted.Rate-pressure product(RPP)were calculated.Results:After anes-thetic induction,BP and RPP in the two groups decreased significantly compared with their preinduction values.As comparison with their postinduction values,the orotracheal intubation in the two groups caused significant increases in BP,HR and RPP.Diastolic blood pressure(DBP)and mean arterial pressure(MAP)increased significantly and lasted for 1-minute in group C compared with the baseline values.Systolic blood pressure(SBP)was not significant change and DBP increased significantly immediately af-ter intubation in group P.HR of both groups after intubation were significantly higher than their baseline values and lasted for 4 min in group C,HR increased significantly immediately after intubation in group P.SBP,DBP,MAP,HR and RPP after intubation in group P were significantly lower than those of group C during the observation period.The value of BIS was similar between the two groups.Compared with group C,the incidence of SBP greater than 30％and RPP greater than 22 000 was significantly lower in group P in the observation period,and no patient in group P developed RPP greater than 22 000.At the end of the incidence of SBP less than 30％of the basal value and HR less than 30％of the baseline,no severe bradycardia occurred in both groups.Conclusion:During double-lumen endobronchial intubation,unilateral thoracic paravertebal block with lidocaine can provide less hemodynamic response and level of conscionsness.
