ObjectiveStudies have shown that nuciferine has anti-cerebral ischemia effect, but the specific mechanism of action has not been elaborated. Based on the transcriptome results, the pharmacological mechanism of nuciferine against cerebral ischemia was analyzed from multiple dimensions including tissue, cell, pathological process, biological process and signaling pathway. MethodsThirty SD rats were randomly divided into the sham group, model group and nuciferine group(40 mg·kg-1) according to weight. Except for the sham group, the model of middle cerebral artery occlusion(MCAO) was established by thread embolization method after 30 min of administration in the other two groups. Twenty-four hours after surgery, transcriptome sequencing was used to detect the gene expression profiles in the cortex penumbra of rat cerebral tissue, and gene ontology(GO) and kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed for differentially expressed genes. The mechanismof nuciferine against cerebral ischemia was analyzed from 5 dimensions of tissue, cell, pathological process, biological process and signaling pathway by the transcriptome-based multi-scale network pharmacology platform(TMNP). ResultsTranscriptome sequencing and gene quantitative analysis showed that 667 genes were significantly reversed by nuciferine. Further enrichment analysis of KEGG and GO suggested that the pathways of nuciferine involved regulating stress response, ion transport, cell proliferation and differentiation, and synaptic function. TMNP research found that at the tissue level, nuciferine could significantly improve the cerebral tissue injury caused by ischemia. At the cellular and pathological levels, nuciferine could play an anti-cerebral ischemia role by improving the state of various nerve cells, mobilizing immune cells, regulating inflammation. And at the level of biological processes and signaling pathways, nuciferine mainly acted on the processes such as vascular remodeling, inflammation-related signaling pathways, and synaptic signaling. ConclusionCombined with the results of transcriptome sequencing, gene quantitative analysis and TMNP, the mechanism of nuciferine against cerebral ischemia may be related to processes such as intervening in stress response and inflammation, affecting vascular remodeling and regulating synaptic function. These results can provide a basis and reference for further study of the pharmacological mechanism of nuciferine against cerebral ischemia.

Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2012 to 2024, and to provide a scientific basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze the incidence data of mumps in Guangxi from 2012 to 2024. Results A total of 159 873 mumps cases were reported from 2012 to 2024 in Guangxi, with an average annual reported incidence of 25.41/100 000, and no death. Mumps occurred every month, with the peak incidence mainly concentrated in April to July and October to January of the next year. There were 96,118 male cases (29.43 /100 000), and 63 755 female cases (21.07 /100 000). The male to female ratio was 1.40:1, and the difference between male and female was significant (χ2=4 321.276,P<0.05). The annual incidence of mumps showed a certain periodic change, with the incidence peak and trough alternating every 4 - 5 years. The majority of patients were under 15 years old, accounting for 85.32% of the total number of cases. The patients mainly included students, preschool children and scattered children. The highest average incidence was in Nanning City with 40 231 cases (42.08/100 000), and the lowest was in Qinzhou City with 3 466 cases (8.16/100 000). From 2012 to 2024, a total of 210 mumps outbreaks with 4 483 cases were reported in Guangxi. Conclusion The incidence of mumps in Guangxi from 2012 to 2024 shows a periodic change and obvious seasonality. People under 15 years old are the key group at risk of mumps. The prevention and control of the epidemic of mumps in schools and kindergartens should be strengthened. It is suggested to carry out long-term monitoring of mumps as well as immune effect research, and continue to maintain a high vaccination rate of 2 doses of mumps-containing vaccines.

Acupuncture, a therapeutic treatment defined as the insertion of needles into the body at specific points (ie, acupoints), has growing in popularity world-wide to treat various diseases effectively, especially acute and chronic pain. In parallel, interest in the physiological mechanisms underlying acupuncture analgesia, particularly the neural mechanisms have been increasing. Over the past decades, our understanding of how the central nervous system and peripheral nervous system process signals induced by acupuncture has developed rapidly by using electrophysiological methods. However, with the development of neuroscience, electrophysiology is being challenged by calcium imaging in view field, neuron population and visualization in vivo. Owing to the outstanding spatial resolution, the novel imaging approaches provide opportunities to enrich our knowledge about the neurophysiological mechanisms of acupuncture analgesia at subcellular, cellular, and circuit levels in combination with new labeling, genetic and circuit tracing techniques. Therefore, this review will introduce the principle and the method of calcium imaging applied to acupuncture research. We will also review the current findings in pain research using calcium imaging from in vitro to in vivo experiments and discuss the potential methodological considerations in studying acupuncture analgesia.

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.

Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P<0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.

Objective:To analyze the clinical features and risk factors of chest tightness variant asthma (CTVA) in children, so as to provide basis for the prevention and management of the disease.Methods:A cross-sectional study was conducted to analyze 178 children aged 6-17 years old who were admitted to the Department of Allergy, Capital Institute of Pediatrics Affiliated Children′s Hospital from January 2021 to January 2023 due to chest tightness. The age was 8.83(7.50, 11.58) years old, with 89 males (50%) and 89 females (50%). According to the diagnosis of CTVA, 130 cases were divided into CTVA group and 48 non-CTVA cases were divided into control group. Demographic data, personal history, family history, clinical features, auxiliary examination results and other data were collected. The clinical characteristics, allergens, FeNO level and pulmonary function parameters of the two groups were analyzed. Logistic regression analysis was used to explore the risk factors of the disease.Results:The proportion of school-age children (6-11 years old) in CTVA group was higher than that of adolescent children (≥12 years old) [(113/130,86.9%) vs (26/48,54.2%), Z=21.985, P<0.01]. The proportion of CTVA combined with eczema [(74/130,56.9%) vs (19/48,39.6%), χ2=4.225, P<0.05] and rhinitis symptoms [(98/130,75.4%) vs (27/48,56.2%), χ2=6.138, P<0.05] was higher. The positive rates of mold sensitization [(52/130,40.0%) vs (11/48,22.9%), χ2=4.474, P<0.05] and multiple sensitization [(71/130,54.6%) vs (18/48,37.5%), χ2=4.108, P<0.05] in inhaled allergens were significantly higher than those of control group. The proportion of elevated FeNO (>20 ppb) in CTVA children was 20.8% (27/130), which was significantly higher than that in control group 4.2%(2/48)( χ2=7.086 ,P<0.01). There were no statistical differences in spirometry parameters FEV 1 and FVC between CTVA group and control group ( P both>0.05). FEV 1/FVC, PEF, FEF 25, FEF 50, FEF 75 and MMEF were significantly lower than those in control group ( P all<0.05). Logistic regression analysis showed that rhinitis symptoms ( OR=2.351, 95% CI 1.105-5.002, P=0.026), multiple sensitizations ( OR=2.184, 95% CI 1.046-4.557, P=0.038), tIgE>60 kU/L( OR=3.080, 95% CI 1.239-7.654, P=0.015), FeNO>20 ppb ( OR=6.734, 95% CI 1.473-30.796, P=0.014) and small airway dysfunction ( OR=3.164, 95% CI 1.089-9.194, P=0.034) were risk factors for chest tightness variant asthma. FeNO combined with FEF 50 has the largest area under the curve ( Z=2.744, P<0.01) in diagnosing CTVA. Conclusion:CTVA is more common in school-age children than in adolescent children. Rhinitis symptoms, multiple sensitization, tIgE>60 kU/L, FeNO>20 ppb and small airway dysfunction are risk factors for chest tightness variant asthma. FeNO combined with small airway indexes can improve the diagnostic value of CTVA.
