Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty, which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas(The Second Batch of Pediatrics) released by the National Administration of Traditional Chinese Medicine(TCM) in September 2022, and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature, this study conducted herbal textual research on Yigongsan from five aspects, including historical evolution, origin and processing, dosage conversion, usage and preparation methods, and functional application, then formed the key information table of this formula, in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study, it is recommended that Panax ginseng should be removed the basal part of stem(rhizoma), Poria cocos should be removed the peel, Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used. According to 4.13 g/Qian(钱), 1 g/slice for ginger, 3 g for each jujube and 300 mL/Zhan(盏), the doses of Ginseng Radix, Poria, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Citri Reticulatae Pericarpium, Zingiberis Rhizoma Recens, Jujubae Fructus were 1.652, 1.652, 1.652, 1.652, 1.652, 5, 6 g, and the total amount was 19.26 g. The decocting method was to crush the medicinal materials into fine powder with 50-80 mesh, add 300 mL of water and decoct to 210 mL for each dose, then remove the dregs and take it warmly. This formula was recorded in ancient books as the main treatment for the cold-deficiency of spleen and stomach, and Qi stagnation in children with vomiting and diarrhea and lack of appetite. It has been flexibly applied by later generations of physicians, and is often used to treat anorexia, inflammation of the digestive tract, diarrhea and other diseases in children.

ObjectiveTo investigate the antidepressant effect of Sinisan (SNS) by regulating glycogen aynthase kinase-3β (GSK-3β)/tumor necrosis factor alpha-induced protein 3(A20)/CCAAT enhancer binding protein β(C/EBPβ) to inhibit the activation of microglia. MethodA total of 72 male C57/6J mice were randomly divided into the normal group, model group, fluoxetine group (5.0 mg·kg-1), low-dose Sinisan group (4.9 g·kg-1), medium-dose Sinisan group (9.8 g·kg-1), and high-dose Sinisan group (19.6 g·kg-1), with 12 mice in each group. After one week of adaptive feeding, chronic unpredictable mild stress (CUMS) was performed to establish the depression model. In the fifth week, drug treatment was conducted for four weeks. In the ninth week, behavioral tests were performed, including sucrose preference test (SPT), open field test (OPT), elevated plus maze (EPM) test, and forced swimming test (FST). Western blot was used to detect the expression levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), nitric oxide synthase (iNOS), GSK-3β, A20, and C/EBPβ in the cortex. The expression of M1-polarized ionized calcium-binding adapter molecule 1 (Iba1) and cluster of differentiation 68 (CD68) in microglia was detected by immunofluorescence. ResultAfter eight weeks of CUMS, compared with the normal group, the mice in the model group had a significantly reduced sucrose preference rate (P<0.01), and the activity in the central area of the OPT was significantly reduced (P<0.01). The activity in the open arm area of the EPM test was significantly reduced (P<0.05), and the immobility time of FST was increased (P<0.01). The expression levels of inflammatory proteins IL-1β, IL-6, and iNOS were increased (P<0.01), and the fluorescence co-localization index of Iba1 and CD68 was increased (P<0.05). The protein expression levels of GSK-3β and C/EBPβ were significantly increased (P<0.05, P<0.01). After four weeks of SNS intervention, compared with the model group, the mice in the SNS group had significantly increased sucrose preference rate (P<0.01), significantly increased activities in the central area and the open arm area in the OPT and the EPM test (P<0.05), and significantly reduced immobility time in the FST (P< 0.01). The protein expression levels of IL-1β, IL-6, and iNOS were significantly decreased (P<0.05), and the fluorescence co-localization index of Iba1 and CD68 was decreased in the high-dose SNS group (P<0.05). The protein expression levels of GSK-3β and C/EBPβ in the medium-dose and high-dose SNS groups were significantly decreased (P<0.01), and that of A20 was significantly increased (P<0.01). ConclusionThe antidepressant effect of SNS is related to the regulation of GSK-3β/A20/C/EBPβ protein expression and the inhibition of M1-type activation of microglia.

Objective:To evaluate the effect of umbilical cord milking (UCM) on neonatal outcomes after cesarean section.Methods:Chinese and English databases (including CNKI, Wanfang, China Biology Medicine Disc, VIP, Yiigle, PubMed, Embase, CINAHL, Web of Science, the Cochrane Library, and Google Scholar) and ClinicalTrials.gov were retrieved from the inception to July 2023. Randomized controlled trials regarding UCM in neonates from different races who were born by cesarean section were included. The outcomes were postnatal hemoglobin level, hematocrit value, peak serum bilirubin level, phototherapy, cord blood pH value, intraventricular hemorrhage, death, polycythemia, neonatal necrotizing enterocolitis, and Apgar score. The risk of bias among the included studies was confined to low or possible risk according to the Cochrane Risk of Bias Assessment Tool 2.0. RevMan5.3 was used for meta-analysis, and subgroup analysis was performed among neonates with different gestational ages. The certainty of evidence was evaluated using the grades of recommendations assessment, development, and evaluation (GRADE) framework.Results:A total of 11 articles involving 2 347 neonates (1 322 full-term and 1 025 preterm infants) were included. Meta-analysis results showed that: (1) Compared with the immediate cord clamping, UCM increased the hemoglobin level within 24 h and 48-72 h after birth ( MD=1.40, 95% CI: 1.11-1.70, Z=9.32; MD=0.86, 95% CI: 0.69-1.02, Z=10.02, both P<0.01), hematocrit value within 24 h and 48-72 h after birth ( MD=2.73, 95% CI: 0.18-5.29, Z=2.09, P=0.04; MD=3.57, 95% CI: 2.29-4.85, Z=5.46, P<0.01). However, no significant differences were found in the peak bilirubin level, phototherapy, cord blood pH, and Apgar score at 1 and 5 min (all P>0.05). (2) Compared with delayed cord clamping, UCM increased the hemoglobin level ( MD=0.83, 95% CI: 0.75-0.91, Z=20.11, P<0.01) and hematocrit value ( MD=2.34, 95% CI: 1.25-3.43, Z=4.20, P<0.01) within 24 h after birth, but not in the hematocrit value at 48-72 h after birth ( MD=-0.38, 95% CI:-2.27-1.52, Z=0.39, P=0.70) or the peak bilirubin level ( MD=-0.65, 95% CI:-2.16-1.04, Z=0.69, P=0.49). Sensitivity analysis showed that for full-term neonates born by cesarean section, the peak bilirubin level in the UCM group was significantly lower than that in the delayed cord clamping group ( MD=-1.30, 95% CI:-2.26-0.34, Z=2.66, P<0.01). Still, the incidence of phototherapy, intraventricular hemorrhage (grade Ⅰ-Ⅳ), death, polycythemia, neonatal necrotizing enterocolitis, and Apgar score at 1 min and 5 min showed no statistical differences (all P>0.05). Conclusions:UCM could increase the short-term postnatal hemoglobin and hematocrit levels in neonates born by cesarean section, which might prevent neonatal anemia in the short term without increasing the adverse neonatal outcomes. Little effects were observed on the peak bilirubin level, phototherapy, polycythemia, etc. More high-quality and large-sample randomized controlled trials are needed in the future.

Herpes zoster ophthalmicus(HZO)is caused by the involvement of the ophthalmic division trigeminal nerve after reactivation of varicella-zoster virus(VZV)latent in the trigeminal ganglia, which usually occurs in the elderly and people with low immune function. The clinical manifestations of HZO are complex and diverse, which show not only keratoconjunctivitis and uveitis, but also retinal necrosis, optic neuropathy, and rare central nervous system lesions. Some cases do not have typical skin lesions, which can easily lead to missed diagnosis, misdiagnosis, and mistreatment, seriously affecting People's life quality. This article aimed to evaluate the clinical manifestations of HZO cases reported in the literature in recent years and comprehensively understand their diversity and complexity to better diagnose and treat the disease. This study also aimed to improve the diagnosis and cure rates of the disease, reduce the maximum number of visual damage, and provide more evidence for the precise diagnosis and treatment of HZO.

Objective:To analyze and compare the health education efforts of respiratory infectious diseases at home and abroad.Methods:The literature related to health education and popular science of respiratory infectious diseases included in the databases of China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) from January 1, 2003 to December 31, 2023 was searched. A total of 4 686 articles were retrieved in CNKI, 1 540 articles unrelated to the theme were excluded, and 3 146 Chinese articles were obtained. In the WOS database, 7 724 articles were retrieved, 3 685 articles about the clinical mechanism of diseases, pharmacology, and other research topics were excluded, and 4 039 English articles were obtained. The information of annual publications, institutions, authors and keywords was analyzed by using CiteSpace visualization software, and the publication status, research hotspots and development trends of health education related to respiratory infectious diseases at home and abroad were analyzed.Results:Since 2003, the number of publications in health education on respiratory infectious diseases at home and abroad had shown a fluctuating growth trend, and in 2020, the field showed a sharp growth trend at home and abroad. There was no core author group in this field in China, and the network density of domestic authors was 0.006 5, and the network density of foreign authors was 0.009 6. The domestic institutions were mainly the Center for Disease Control and Prevention and medical institutions, including Guangzhou Chest Hospital (29 articles) and the Chinese Center for Disease Control and Prevention (10 articles); Foreign research institutions were mainly higher education institutions, including the University of London (91 articles) and Harvard University (67 articles). The network density of domestic was 0.001 3, and the network density of foreign publishing institutions was 0.026 3, the network density was greater than that of Chinese publishing institutions. The emergence of "COVID-19" "Avian influenza" "Knowledge, Attitude, Practice" and "mental health" in China had strong burst (burst intensity: 46.41, 12.12, 10.33, 8.5); "Coronavirus" "coverage" "Avian influenza" and "COVID-19 vaccine" in foreign countries had strong burst (burst intensity: 14.34, 11.06, 10.73, 10.02).Conclusions:At present, the health education of respiratory infectious diseases at home and abroad has received great attention. But the cooperation between domestic authors and research institutions is loose, and the close collaboration needs to be strengthened. There are differences in the research focus of health education on respiratory infectious diseases at home and abroad.

Background and aim:Few studies have reported hepatitis B surface antigen(HBsAg)kinetics after nucleos(t)ide analog(NA)discontinuation in patients with noncirrhotic chronic hepatitis B(CHB).The study specifically investigated long-term HBsAg kinetics after NA discontinuation. Methods:Between January 2014 to January 2024,this study prospectively enrolled 106 outpatients with noncirrhotic CHB who met the discontinuation criteria after NA consolidation treatment.Demographic,clinical,and laboratory data were collected and analyzed after NA discontinuation. Results:Ninety-six patients who finished 5 years of follow-up were included.HBsAg remained unde-tectable in 29 patients with end of treatment(EOT)HBsAg negativity.Among 67 patients with EOT HBsAg positivity,HBsAg seroclearance occurred in 12(17.9%)patients with an estimated annual inci-dence of HBsAg seroclearance of 3.6%.Patients with EOT HBsAg levels of ≤1000 IU/mL had a higher HBsAg seroclearance rate than those with EOT HBsAg levels of>1000 IU/mL(33.3%vs.5.4%).The pro-portion of patients with HBsAg ≤1000 IU/mL increased during follow-up.Logistic regression analysis indicated that the EOT HBsAg level was an independent factor for HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL.The optimal EOT HBsAg cutoff for both HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL was 359 IU/mL. Conclusions:Patients with EOT HBsAg negativity experienced no relapse and maintained HBsAg sero-clearance during 5 years of follow-up after NA discontinuation.A higher HBsAg seroclearance rate can be obtained in patients with EOT HBsAg levels of ≤1000 IU/mL during 5 years of follow-up after NA discontinuation.Close monitoring and proper NA retreatment are recommended to guarantee the safety of NA discontinuation.
