This paper aimed to explore the antidepressant effect of the essential oil from Schizonepeta tenuifolia Briq.(EOST) on the treatment of depression and its mechanism by using a combination of network pharmacology and the mouse model of lipopolysaccharide(LPS)-induced depression. The chemical components in EOST were identified using gas chromatography-mass spectrometer(GC-MS), and 12 active components were selected as the study objects. The targets related to EOST were obtained by Traditional Chinese Medicines Systems Pharmacology(TCMSP) and SwissTargetPrediction database. The targets related to depression were screened out through GeneCards, Therapeutic Target Database(TTD), and Online Mendelian Inheritance in Man(OMIM) database. The Venny 2.1 was applied to screen out the common targets of EOST and depression. The targets were imported into Cytoscape 3.7.2 to generate "drug-active component-diease-target" network diagram. The protein-protein interaction(PPI) network was constructed using STRING 11.5 database and Cytoscape 3.7.2, and the core targets were screened out. DAVID 6.8 database was used for Gene Ontology(GO) func-tional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis, and subsequently the enrichment results were visualized through the bioinformatics platform. The mouse model of depression was induced by intraperitoneally injecting with LPS in mice. Before modeling, mice were administrated orally with EOST. The antidepressant effect of EOST was evalua-ted by tail suspension test(TST), forced swimming test(FST), and novelty suppressed feeding test(NSFT) after modeling. The content of interleukin(IL)-1β was determined by enzyme-linked immunosorbent assay(ELISA), and the protein expression levels of IL-1β and pro IL-1β in the hippocampus were determined by Western blot. There were 12 main components and 179 targets in EOAT, of which, 116 targets were related to depression, mainly involved in neuroactive ligand-receptor interaction, calcium signaling pathway, and cyclic adenosine monophosphate(cAMP) signaling pathway. Biological processes such as synaptic signal transduction, G-protein coupled receptor signaling pathway, and chemical synaptic transmission were involved. Molecular functions such as neurotransmitter receptor activity, RNA polymerase Ⅱ transcription factor activity, and heme binding were involved. In mice experiments, the results showed that EOST at 100 mg·kg~(-1) and 50 mg·kg~(-1) significantly shortened the immobility time in TST and FST as well as the feeding latency in NSFT compared with the model group, decreased the levels of serum IL-1β and NO, and reduced the protein expression levels of IL-1β and pro IL-1β in the hippocampus. In conclusion, EOST shows a good antidepressant effect in a multi-component, multi-target, and multi-pathway manner. The mechanism may be attributed to the fact that EOST can down-regulate the protein expression levels of IL-1β and pro IL-1β, decrease the release of inflammatory factors, and reduce neuroinflammation response.

Objective:To explore the association between atypical small acinar proliferation(ASAP)and subsequent diagnosis of intermediate and high risk prostate cancer(PCa),and analyze whether delaying repeat biopsy timing is safe and effective.Meth-ods:From June 2000 to June 2022,we retrospectively analyzed the clinical data of 276 patients accepting prostatic biopsy and diag-nosed with ASAP in China-Japan Union Hospital of Jilin University.54.7％(151/276)patients had a repeat biopsy.We used statis-tic methods to process the data.Results:25.2％(38/151)patients were diagnosed with PCa on repeat biopsy.Among them,78.9％(30/38)patients had Gleason score(GS)3+3 and 21.1％(8/38)had GS 3+4 disease.There were 4 and 6 patients got RP re-spectively in the two cohorts.Only 5.3％(8/151)of ASAP patients were diagnosed as intermediate risk PCa in repeated biopsy and specially,no high risk PCa was identified in our study.Conclusion:It was safe and valid to delay the repeat biopsy.

OBJECTIVE: To clarify the functional effects of differential expression of ring finger and tryptophan-aspartic acid 2 (RFWD2) on dendritic development and formation of dendritic spines in cerebral cortex neurons of mice. METHODS: Immunofluorescent staining was used to identify the location and global expression profile of RFWD2 in mouse brain and determine the co-localization of RFWD2 with the synaptic proteins in the cortical neurons. We also examined the effects of RFWD2 over-expression (RFWD2-Myc) and RFWD2 knockdown (RFWD2-shRNA) on dendritic development, dendritic spine formation and synaptic function in cultured cortical neurons. RESULTS: RFWD2 is highly expressed in the cerebral cortex and hippocampus of mice, and its expression level was positively correlated with the development of cerebral cortex neurons and dendrites. RFWD2 expression was detected on the presynaptic membrane and postsynaptic membrane of the neurons, and its expression levels were positively correlated with the length, number of branches and complexity of the dendrites. In cultured cortical neurons, RFWD2 overexpression significantly lowered the expressions of the synaptic proteins synaptophysin (P < 0.01) and postsynapic density protein 95 (P < 0.01), while RFWD2 knockdown significantly increased their expressions (both P < 0.05). Compared with the control and RFWD2-overexpressing cells, the neurons with RFWD2 knockdown showed significantly reduced number of dendritic spines (both P < 0.05). CONCLUSION RFWD2 can regulate the expression of the synaptic proteins, the development of the dendrites, the formation of the dendritic spines and synaptic function in mouse cerebral cortex neurons through ubiquitination of Pea3 family members and c-Jun, which may serve as potential treatment targets for neurological diseases.

Objective:To investigate the intervention effect of n-butyl alcohol extracts from Xiaoyaosan against depression-like behavior induced by chronic unpredictable mild stress （CUMS） in model mice and the role of insulin-like growth factor-1 receptor β （IGF-1Rβ）/phosphatidylinositol-3 kinase （PI3K）/protein kinase B （Akt） signaling pathway in such intervention. Method:The effective dose of n-butyl alcohol extracts from Xiaoyaosan was preliminarily determined in model mice with behavioral despair. Then the male C57BL/6 mice were randomly divided into the blank group， model group， fluoxetine group， Xiaoyaosan group， and the low- （20 g·kg^-1） and high-dose （40 g·kg^-1） n-butyl alcohol extract groups. The mice in all groups except for the blank group were exposed to CUMS for inducing the depression-like behavior， which was judged by the sucrose preference test （SPT）. The successfully modeled mice in the medication groups were intragastrically administered with the corresponding drugs， whereas those in the blank and model groups were treated with an equal volume of solvent for five successive weeks. Following the SPT， tail suspension test （TST）， and novelty suppressed feeding test （NSFT） at the end of the fifth week， the insulin-like growth factor-1 （IGF-1） levels in mouse serum and hippocampus were measured by enzyme-linked immunosorbent assay （ELISA）. The average optical density （IA） of Nissl bodies in mouse hippocampal CA3 region was detected by toluidine blue staining. The 5-bromo-2-deoxyuridine （Brdu） and doublecortin （DCX） expression in the dentate gyrus （DG） was assayed using immunofluorescence method. The protein expression levels of IGF-1Rβ， PI3K， phosphorylated-PI3K （p-PI3K）， Akt， p-Akt， cysteine aspartic acid-specific protease 3 （Caspase-3）， and cleaved Caspase-3 in the hippocampus were determined by Western blot. Result:The results of forced swimming test and TST showed that n-butyl alcohol extracts from Xiaoyaosan at 9.1 and 40 g·kg^-1 both significantly shortened the immobility time of mice （P<0.05， P<0.01）， indicating that the effective dose ranged from 9.1-40 g·kg^-1. Compared with the model control， the n-butyl alcohol extracts from Xiaoyaosan at 20 and 40 g·kg^-1 significantly increased the sucrose preference percentage （P<0.05， P<0.01）， shortened the immobility time in TST （P<0.01） and the feeding latency in NSFT （P<0.01）， reversed the down-regulated IGF-1 content in mouse serum and hippocampus （P<0.01）， increased the AOD of Nissl bodies in the hippocampal CA3 region （P<0.01）， promoted the expression of Brdu and DCX in DG （P<0.05， P<0.01）， and down-regulated the protein expression levels of IGF-1Rβ （P<0.05， P<0.01）， p-PI3K/PI3K （P<0.05， P<0.01）， p-Akt/Akt （P<0.05）， and cleaved Caspase-3/Caspase-3 in the hippocampus of CUMS mice. Conclusion:The n-butyl alcohol extracts from Xiaoyaosan are equivalent to Xiaoyaosan in inhibiting expression. They alleviate the depression-like behavior in CUMS mice， induce the production of Nissl bodies in hippocampal CA3 region， enhance neuronal proliferation and differentiation in DG， and facilitate neurogenesis. All these may be related to the inhibition of over-activated IGF-1Rβ/PI3K/Akt pathway and the reduction of neuronal apoptosis.

BACKGROUND: Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China. METHODS: The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD. RESULTS: A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05). CONCLUSION Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

OBJECTIVE: To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients. METHODS: A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented. RESULTS: The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns. CONCLUSION Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).
