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.

Polysaccharides, predominantly extracted from traditional Chinese medicinal herbs such as Lycium barbarum, Angelica sinensis, Astragalus membranaceus, Dendrobium officinale, Ganoderma lucidum, and Poria cocos, represent principal bioactive constituents extensively utilized in Chinese medicine. These compounds have demonstrated significant anti-inflammatory capabilities, especially anti-liver injury activities, while exhibiting minimal adverse effects. This review summarized recent studies to elucidate the hepatoprotective efficacy and underlying molecular mechanisms of these herbal polysaccharides. It underscored the role of these polysaccharides in regulating hepatic function, enhancing immunological responses, and improving antioxidant capacities, thus contributing to the attenuation of hepatocyte apoptosis and liver protection. Analyses of molecular pathways in these studies revealed the intricate and indispensable functions of traditional Chinese herbal polysaccharides in liver injury management. Therefore, this review provides a thorough examination of the hepatoprotective attributes and molecular mechanisms of these medicinal polysaccharides, thereby offering valuable insights for the advancement of polysaccharide-based therapeutic research and their potential clinical applications in liver disease treatment.

AIM: To investigate the effect of the timing of satisfactory sedation with preoperative oral midazolam on anesthesia induction and recovery in children undergoing adenotonsillectomy. METHODS: A total of 147 children undergoing elective adenotonsillectomy, with ASA physical status orⅡ, aged 2-7 years were selected from November 2022 to June 2023 in the Second Affiliated Hospital of Wenzhou Medical University. The children were orally administered 0.5 mg/kg midazolam in preoperative waiting area and were divided into 10-20 min (rapid onset, M1 group) and 21-30 min (slow onset, M2 group) based on the satisfactory sedation time, or equal volume of sugar pear drink orally (blank control group, C group). Children in all three groups received a general anesthesia method of propofol+fentanyl combined with sevoflurane induction and sevoflurane maintenance. The primary outcome measures were the induction compliance checklist (ICC) score and the pediatric anesthesia emergence delirium (PAED) score in the post-anesthesia care unit (PACU) to assess the occurrence of emergence agitation (EA), and the secondary outcome measures included the parental separation anxiety scale (PSAS), sedation Ramsay score, surgery duration, recovery time, PACU stay time, discharge time, the incidence of perioperative respiratory adverse events (PRAE) and other adverse events in the ward. RESULTS: 147 children were included in the result analysis, with 49 cases in each group. The proportion of perfect induction (ICC=0) were significantly higher in two M groups than that in group C (95.9% vs. 91.8% vs. 61.2%, P=0.001). The maximum and average PAED score in PACU in group M1 showed a significantly higher (6.4±5.0 vs. 4.4 ± 4.1, P=0.029; 5.2 ± 4.5 vs. 3.4 ± 3.6, P=0.030), and the incidence of EA was significantly higher than those in group C (10.2% vs. 30.6%, P=0.022), and increased compared to the group M2 (OR= 0.581, 95%CI 0.231-1.463, P=0.354). There was no statistically significant difference in the maximum and average PAED scores, incidence of EA between group M2 and group C (P>0.05). The Ramsay score and PSAS score in two M groups were higher, PACU stay time and recovery time was longer than those in group C (P<0.05). The pain scores in PACU in group M1 was higher than that of group C (P<0.05). There was no statistically significant difference in the surgical time, discharge time, the incidence of PRAE and other adverse events in the ward among three groups (P>0.05). CONCLUSION: Preoperative oral midazolam can improve the ICC and PSAS scores of children during induction, but it also leads to prolonged recovery time and PACU retention time. The rapid onset of midazolam did not result in better induction and recovery quality, but instead increased the incidence of EA and postoperative pain score.

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation (EP) and explore the possible risk factors of liver injury, so as to provide a reference for the safe clinical application of Epimedii Folium (EF). MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend, indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men, with an onset age range of 15-91 years old and a median onset age of 60 years old (median onset ages for men and women are 59 and 60 years old, respectively). The time span from taking EP alone to the occurrence of liver injury is 1-386 days, with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days, with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney, indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors, it is found that patients have unreasonable medication methods such as excessive dosage, repeated use, and multi-drug combination, which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP, and in clinical use, it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.

BACKGROUND:Persistent hyperglycemia has been identified as promoting neurovascular dysfunction,leading to irreversible endothelial dysfunction,increased neuronal apoptosis,oxidative stress and inflammation.These changes in combination or alone lead to microvascular and macrovascular lesions as well as progressive neuropathy.Noncoding RNAs may provide a new strategy for understanding the etiology,pathogenesis and treatment of the disease. OBJECTIVE:To review the role and mechanism of noncoding RNAs in the occurrence and development of diabetic peripheral neuropathy by reviewing relevant literature at home and abroad,in order to provide new ideas and approaches for noncoding RNAs in the prevention,diagnosis and treatment of diabetes neuropathy. METHODS:CNKI and PubMed were retrieved for relevant literature published from database inception to 2022.The key words were"noncoding RNA;lncRNA;miRNA;diabetes peripheral neuropathy;expression profile"in Chinese and English,respectively.The retrieved documents were summarized and analyzed,and 61 articles were finally selected for further review. RESULTS AND CONCLUSION:(1)Noncoding RNA plays a key role in the pathophysiological process of diabetic peripheral neuropathy.Among the most widely studied regulatory noncoding RNA species,there are long noncoding RNAs,circular RNAs and microRNAs.(2)Through the regulation of noncoding RNAs,the activation or inhibition of related cell pathways,inflammatory genes and downstream-related cytokines will inhibit cell apoptosis,improve inflammation,and thus change the expression of target genes to participate in the process of diabetic neuralgia.(3)Although many microRNAs and long noncoding RNAs have been found to participate in diabetic peripheral neuropathy,the mechanisms of many noncoding RNAs are unclear,and the same noncoding RNAs may play different roles in different modes.Therefore,it is necessary to further study their action modes in disease etiology and pathology,thereby clarifying their role in the pathogenesis of diabetic peripheral neuropathy.However,the criteria for evaluating noncoding RNA activity have not yet been established,and further research is needed on which specific noncoding RNAs play a dominant regulatory role.(4)MicroRNAs,long noncoding RNAs and their target genes can regulate progressive neuropathy,which are expected to become new targets for the clinical prevention and treatment of diabetic peripheral neuropathy and new biomarkers for the development and prognosis of diabetic peripheral neuropathy.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:
To investigate the association between high normal blood pressure, hypertension and microalbuminuria (MAU), so as to provide the basis for early screening and prevention of renal injury caused by hypertension.
Methods:
A multi-stage cluster random sampling method was used to select permanent residents aged 18 to 75 years from six provinces including Hebei, Hunan, Sichuan, Heilongjiang, Qinghai and Jiangxi from September to October 2021. Basic information and lifestyle behaviors were collected through questionnaires. Indices including height, weight and blood pressure were measured. Urinary microalbumin and creatinine were measured in 24-hour urine samples. The associations between high normal blood pressure, hypertension, and MAU were analyzed by using a multivariable logistic regression model.
Results:
A total of 1 982 residents were surveyed, with 996 residents aged <50 years (50.25%) and 986 residents aged ≥50 years (49.75%). There were 958 males (48.34%) and 1 024 females (51.66%). Normal blood pressure was observed in 653 residents (32.95%), high normal blood pressure in 748 (37.74%) and hypertension in 581 (29.31%). MAU was detected in 164 participants, with a detection rate of 8.27%. The detection rates of MAU among residents with normal blood pressure, high normal blood pressure, and hypertension were 2.14%, 8.16% and 15.32%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that after adjusting for gender, age, educational level, smoking, alcohol consumption, regular exercise and body mass index, the residents with high normal blood pressure (OR=3.535, 95%CI: 1.898-6.585) and hypertension (OR=7.232, 95%CI: 3.808-13.732) had higher risks of MAU compared to those with normal blood pressure; the residents with hypertension (OR=1.914, 95%CI: 1.340-2.735) had a higher risk of MAU compared to those with high normal blood pressure.
Conclusions
High normal blood pressure and hypertension are associated with an increased risk of MAU.
