Sepsis is a systemic inflammatory response syndrome caused by the invasion of pathogenic microorganisms such as bacteria. In addition to the manifestations of systemic inflammatory response syndrome and primary infection lesions， critical cases often have manifestations of organ hypoperfusion. The morbidity and mortality of sepsis have remained high in recent years， which seriously affect the quality of life of the patients. The pathogenesis of sepsis is complicated， in which uncontrollable inflammation is a key mechanism. The phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a key role in mediating inflammation in sepsis. The available therapies of sepsis mainly include resuscitation， anti-infection， vasoactive drugs， intensive insulin therapy， and organ support， which show limited effects of reducing the mortality. Therefore， finding new therapeutic drugs is a key problem to be solved in the clinical treatment of sepsis. In recent years， studies have shown that traditional Chinese medicine （TCM） can regulate the PI3K/Akt pathway via multiple pathways， multiple effects， and multiple targets to inhibit inflammation and curb the occurrence and development of sepsis， which has gradually become a hot spot in the prevention and treatment of sepsis. Moreover， studies have suggested that TCM has unique advantages in the treatment of sepsis. TCM can regulate the PI3K/Akt signaling pathway to inhibit inflammation， reduce oxidative stress， and control apoptosis in the prevention and treatment of sepsis. Despite the research progress， a systematic review remains to be performed regarding the TCM treatment of sepsis by regulating the PI3K/Akt signaling pathway. After reviewing relevant papers published in recent years， this study systematically summarizes the relationship between PI3K/Akt pathway and sepsis and the role of TCM in the treatment of sepsis， aiming to provide new ideas for the potential treatment of sepsis and the development of new drugs.

Objective: To explore differences in the factors influencing parents and teachers assessments of preschool children s mental health using the Strengths and Difficulties Questionnaire (SDQ), so as to provide reference for promoting children s mental health. Methods: A retrospective analysis was conducted on the SDQ survey data of 14 763 middle and senior kindergarten children in Nanshan District, Shenzhen, from March to June 2023. Chi square χ 2 tests were used to analyze differences in mental health assessments between parents and teachers. Multivariate Logistic regression was employed to examine the factors influencing parental assessments, and Kappa coefficients were used to evaluate the consistency between parent and teacher evaluations. Results: The positive rate of mental health problems reported by parents (7.2%) was significantly higher than that reported by teachers (6.2%) ( χ 2=254.27, P <0.01). Gender differences revealed that parents reported a lower positive rate for boys (7.9%) compared to teachers (8.5%), whereas for girls, the parental positive rate (6.4%) was higher than that reported by teachers (3.8%) ( χ 2=163.59, 81.26, all P <0.01). Age related differences showed that parental positive rates for 4, 5, and 6 year olds (8.5%, 7.4%, 5.8%) were consistently higher than teachers assessments (6.3%, 6.7%, 5.4%) ( χ 2=41.23, 157.53, 63.67, all P <0.05). Univariate analysis of parental assessments indicated higher positive rates among boys (7.9%), 4 year olds (8.5%), mothers aged 20-35 ( 6.6 %), mothers with high school education or below (9.8%), fathers aged 23-40 (6.4%), fathers with high school education or below (10.3%), and children exposed to secondhand smoke (7.9%) ( χ 2=23.56-235.24, all P <0.01). Multivariate Logistic regression identified lower parental education levels and exposure to secondhand smoke as significant risk factors for abnormal SDQ assessments by parents ( χ 2=2.05, 1.62, 3.15, all P <0.05). The Kappa coefficients for parent-teacher agreement across SDQ subscales and total difficulties ranged from 0.04 to 0.12 (all P <0.01). Conclusions Parental education level and exposure to secondhand smoke are significant factors influencing preschool children s mental health. Differences exist between parental and teacher assessments of children s mental health, and incorporating teacher evaluations can provide a more comprehensive understanding of preschoolers psychological well being.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Synthetic biology is a crucial tool for the development of the bio-industry and bio-economy, representing a significant aspect of new quality productive forces. As a core course for graduate students in bioengineering, Synthetic Biology plays a vital role in ensuring the supply of essential talents for the development of the bio-industry in the new era. To better serve regional economic development and provide high-level talents for China's progress in the bio-industry, we analyzed typical issues encountered in the past teaching activities, set up a multi-disciplinary teaching team, optimized the course contents, adjusted the teaching mode, and mobilized students' learning interest. With the application of scientific research project as the starting point, we guided students to think and discuss deeply through the simulation of application writing and project defense, which improved students' critical thinking and innovative thinking. With industrialization as a focus, we explored a new training model combining production, education, and research through the joint practice base of the university and enterprises introduced typical cases of biomanufacturing to encourage students to engage in scientific research. The teaching reform significantly enhances the comprehensive abilities and national sentiments of graduate students. This paper hopes to serve as a reference for colleagues engaged in teaching in this field.

Acute pancreatitis （AP） is one of the most clinically common acute digestive disorders characterized by quick onset，rapid progression，severe condition，and high mortality. If the disease is not timely intervened in the early stage，it can develop into severe AP in the later stage，which damages the long-term quality of life and brings serious economic burden to patients and their families. However， the pathogenesis of this disease is complex and has not been fully explained. The generation and development of AP is closely related to many signaling pathways. Among them，Toll-like receptor 4（TLR4），as a transmembrane signal transduction receptor，can mediate immune response and inflammatory response，and play a key role in the occurrence and development of AP. Traditional Chinese medicine（TCM）can regulate the TLR4 signaling pathway with multiple targets，multiple effects，and multiple administration methods to inhibit inflammatory response，and effectively intervene in the progression of AP， which has gradually become a new craze for preventing and treating AP. Many studies have shown that TCM has obvious advantages in the prevention and treatment of AP. It can effectively treat AP by regulating TLR4 signaling pathway，strengthening immune resistance and defense，and inhibiting inflammatory response. Despite of the research progress，there is still a lack of comprehensive review on TCM regulation of TLR4 signaling pathway in the treatment of AP. Therefore，the literature on TCM regulation of TLR4 signaling pathway published in recent years was systematically reviewed and elaborated，aiming to provide new ideas for the treatment of AP and further drug development.

AIM: To investigate the efficacy and safety of paclitaxel albumin assisted platinum chemotherapy in the treatment of recurrent and metastatic cervical cancer based on tumor factors and inflammatory status. METHODS: A total of 100 patients with recurrent and metastatic cervical cancer in our hospital from January 2020 to January 2023 were randomly divided into two groups: 50 patients in the control group were treated with paclitaxel-assisted nedaplatin regimen, and 50 patients in the study group were treated with paclitaxel-assisted nedaplatin regimen. The short-term efficacy, tumor factors, inflammatory factors, relapse-metastasis related indexes, quality of life, functional status and adverse reactions were compared between the two groups. RESULTS: The total remission rate of the study group (72.00%) was higher than that of the control group (48.00%) (P<0.05). In the study group, after one and three cycles of treatment, serum cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), carbohydrate antigen 724 (CA724), squamous cell carcinoma antigen (SCC Ag), interleukin-4 (IL-4), interleukin-6 (IL-6), tumor necrosis factor - α (TNF-α) The levels of serum microrna-367 (mir-367), microrna -383 (mir-383), quality of life (QOL) and Karnofsky functional status score (KPS) in the tumor patients were significantly higher than those in the control group (P<0.05); There was no significant difference in the incidence of nausea / vomiting, diarrhea, fatigue, leukopenia and allergic reactions between the study group and the control group during treatment (P>0.05), but the total incidence of adverse reactions (12.00%) was lower than that of the control group (32.00%) (P<0.05). CONCLUSION: Paclitaxel albumin-assisted nedaplatin has a reliable effect in the treatment of recurrent and metastatic cervical cancer, which can further reduce the level of tumor factors, relieve inflammation, and has high safety.

Objective To analyze the clinical characteristics of organizing pneumonia secondary to inva-sive pulmonary aspergillosis.Methods A total of 13 patients with organizing pneumonia secondary to invasive pulmonary aspergillosis in the Department of Respiratory,the First Affiliated Hospital of Zhengzhou Univer-sity diagnosed by pathology from January 2019 to January 2021 were retrospectively included,and their clinical characteristics,laboratory examination,imaging characteristics,treatment and prognosis were comprehensively analyzed.Results Most cases of pulmonary aspergillosis occurred within 2-3 weeks of diagnosis,with coug-hing,expectoration,fever,and elevated C-reactive protein and erythrocyte sedimentation rate.Chest computed tomography showed patchy shadows around the original infection focus,mostly accompanied by consolidation,halo sign,bronchial inflation sign,and might be accompanied by cavity and pleural effusion;secondary multi lobed involvement of both lungs was observed,mostly with small patchy shadows,nodular shadows,and tree bud signs.After receiving glucocorticoid treatment,the symptoms were controlled within one week,and the glucocorticoid treatment course was mostly 3-6 months.Conclusion The clinical characteristics of organi-zing pneumonia secondary to invasive pulmonary aspergillosis are somewhat similar to those of cryptogenic or-ganizing pneumonia and have a better prognosis.

Objective To investigate the immediate brain effect of acupuncture at Fengchi using amplitude of low-frequency fluctuation(ALFF)and functional connectivity by the resting-state functional magnetic resonance imaging(rs-fMRI)in patients with posterior circulation ischemia vertigo(PCIV).Methods Twenty patients with PCIV were enrolled.The dizziness handicap inventory(DHI)was used to evaluate the severity of vertigo.The patients were randomly divided into acupuncture group and sham acupoint acupuncture group.Rs-fMRI scan was performed before and after acupuncture.MATLAB-based DPABI 6.1 software was used to analyze rs-fMRI data.Correlation analysis was used between the altered ALFF values and DHI scores.The regions of altered ALFF were taken as seeds to analyze functional connectivity.Results Compared with the sham acupoint acupuncture group,the increased ALFF values were mainly located on the left precuneus,left superior frontal gyrus and left caudate nucleus after acupuncture in the acupuncture group;the decreased ALFF values were mainly located on the left cerebellum and right inferior occipital gyrus.The ALFF value of the left superior frontal gyrus was negatively correlated with the DHI score(P=0.04).The increased functional connectivity was mainly found between left precuneus and the right middle frontal gyrus,the right superior frontal gyrus,the decreased functional connectivity was mainly found between left precuneus and the bilateral paracentral lobule and right cerebellum.Conclusion The ALFF value and functional connectivity are different before and after acupuncture,indicating that the vestibular network,visual and motor brain regions functional activities are changed after needling at Fengchi,which may be the brain functional basis of Fengchi for vertigo in PCIV.
