ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Tongxieyao Prescription is a classic prescription for the treatment of liver-spleen disharmony, which is widely used in the treatment of gastrointestinal diseases such as inflammatory bowel disease, functional diarrhea and chronic colitis. This article explored the correlation between the properties, chemical components, and pharmacological effects of Chinese materia medica in the treatment of gastrointestinal diseases based on the theory of drug delivery in Tongxieyao Prescription. It can be preliminarily inferred that the overall medicinal properties of Tongxieyao Prescription are warm, bitter, sweet, pungent and sour, and belong to the liver and spleen meridians. The ascending, descending, floating and sinking properties have a "rising" trend, which has the effects of gastrointestinal mucosal protection, intestinal flora regulation, gastrointestinal motility improvement and so on. Combined with the concept of "five principles" of TCM quality marker (Q-marker), the potential Q-marker of Tongxieyao Prescription was predicted and analyzed. It was considered that atractylenolide Ⅰ, atractylenolide Ⅱ, atractylenolide Ⅲ, paeoniflorin, synephrine, hesperidin, tangeretin, nobiletin, prim-O-glucosylcimifugin, 5-O-methylvisammioside, etc. could be used as Q-markers and quality control indicators of this prescription.

Acute urinary retention(AUR)occurs frequently among astronauts on orbit.The current treatment is complex and easy to damage the urethra,which seriously affects the life and work of astronauts.In contrast,acupuncture,a traditional Chinese remedy,has shown promising results in managing urinary retention.However,the specific acupoints that could potentially prevent AUR remain uncertain due to the unique physiological conditions experienced by individuals in space compared to those on Earth.To address this gap,our research delved into the mechanisms of AUR and acupuncture within both traditional Chinese medicine and modern medical practices.We conducted a thorough literature review from Pubmed,Web of Science,CNKI,Wanfang database,VIP database and Chinese Medical Code database.A hierarchical evidence-scoring approach was utilized to analyze the included literatures,thus devised acupuncture protocols for the treatment of AUR.The outcomes of our study aim to establish a foundation for the application of acupuncture in managing AUR.

Under the influence of long-term space flights and the confined space environment,it is very easy to induce space depression syndrome,mainly manifested as decreased emotional stability,sleep disorders,mental fatigue,etc.,which seriously affect the living conditions and working abilities of astronauts.The current treatment methods mainly focus on psychological support and drug intervention.Acupuncture has a good effect in treating depression.Therefore,starting from the TCM pathogenesis and modern medical pathogenesis of aerospace depression syndrome,we conducted literature retrieval from databases such as the Chinese Medical Classic,China National Knowledge Infrastructure(CNKI),Wanfang,VIP,PubMed,and Web of science.For the included literature,we adopted the stratified evidence scoring method and combined the TCM mechanism and modern medical mechanism of the effect of acupuncture.A prescription for acupuncture points was constructed to provide a basis for selecting acupuncture points for the prevention of aerospace depression syndrome through acupuncture.

Nasal drug delivery efficiency is highly dependent on the position in which the drug is deposited in the nasal cavity. However, no reliable method is currently available to assess its impact on delivery performance. In this study, a biomimetic nasal model based on three-dimensional (3D) reconstruction and three-dimensional printing (3DP) technology was developed for visualizing the deposition of drug powders in the nasal cavity. The results showed significant differences in cavity area and volume and powder distribution in the anterior part of the biomimetic nasal model of Chinese males and females. The nasal cavity model was modified with dimethicone and validated to be suitable for the deposition test. The experimental device produced the most satisfactory results with five spray times. Furthermore, particle sizes and spray angles were found to significantly affect the experimental device's performance and alter drug distribution, respectively. Additionally, mometasone furoate (MF) nasal spray (NS) distribution patterns were investigated in a goat nasal cavity model and three male goat noses, confirming the in vitro and in vivo correlation. In conclusion, the developed human nasal structure biomimetic device has the potential to be a valuable tool for assessing nasal drug delivery system deposition and distribution.

The construction of experimental animal models plays an important supporting role in research into the mechanisms of action of Chinese medicines.There have been increasing reports of the construction and evaluation of animal models of spleen deficiency;however,the construction method have involved different standards and there has been insufficient objectification of the evaluation indexes.In this review,we summarize the construction and evaluation method of animal models of spleen deficiency from the aspects of animal selection,model establishment,macroscopic characterization,behavioral experiments,and objective indexes of spleen deficiency,with a view to providing theoretical guidance for the construction of experimental animal models of spleen deficiency and references for the selection of animal model platforms for spleen deficiency.

Astronauts are affected by the space environment,and there are health problems in many systems of the body,which seriously affect the on-orbit work efficiency and the health recovery after landing.Although measures have been taken,there are still deficiencies.Acupuncture can regulate the body in a multi-target,multi-level and multi-system way to protect the health of astronauts,which is an effective measure to protect the health problems of astronauts.But there is no acupoint group database for aerospace medical problems,which limits the application of acupuncture in space.The aim of this paper is to solve the possible aerospace medical problems of astronauts by acupuncture.Firstly,the acupuncture indications in aerospace medicine are determined through literature research,expert consultation and expert consensus,and then the evidence collection,evidence evaluation and evidence aggregation are carried out through the"stratified evidence evaluation method"for ancient literature,modern literature and expert experience.Finally,acupoint prescriptions were recommended based on the comprehensive score of acupoints,and acupuncture prescriptions for all acupuncture indications in aerospace medicine were integrated to form an acupoint group database,so as to contribute more Chinese wisdom and solutions to solve aerospace medicine problems.

ObjectiveTo determine the prevalence of avian influenza viruses in the external environment of poultry in Anqing City， Anhui Province， and provide scientific evidence for prevention and control of animal-derived influenza in humans. MethodsA total of 28 farmers’ markets/farms in 10 counties （cities， districts） of Anqing City， Anhui Province， were selected as surveillance sites by simple random sampling strategy. Poultry faeces and other related samples were collected for 6 consecutive weeks. Real-time fluorescence quantitative PCR was used to examine the nucleic acids of influenza A virus. Subtypes H5， H7， and H9 of avian influenza virus were further tested in the positive samples. ResultsA total of 426 specimens were collected， among which 113 tested positive with a positive rate of 26.53%. Among the positive specimens， 104 were determined to be subtype H9， accounting for 92.04%. It did not significantly differ in the positive rate between the main and non-main urban areas （χ²<0.01， P>0.05） or among the specimens collected in different weeks （χ²=7.57， P>0.05）. However， it significantly differed in the positive rate among the specimens collected in the third week and other weeks （χ²=6.89， P<0.05）. Furthermore， among the different sampling sites， farms had the highest positive rate of 46.67%. Among the specimens from different sources， the surface-coated specimens from poultry cages had the highest positive rate of 34.78%. ConclusionAvian influenza viruses are prevalent in the external environment of poultry in Anqing City. It warrants strengthening the surveillance and risk assessment to reduce the virus transmission in the external environment and risk of human infection with animal-derived influenza.

Objective:To analyze the clinical features, risk factors of the prognosis and recurrence of first diagnosed acute disseminated encephalomyelitis(ADEM)in children.Methods:The clinical characteristics of 32 children with first diagnosed ADEM who were treated in the Department of Neurology of Shanghai Children′s Medical Center from January 1, 2012 to January 31, 2022 were analyzed retrospectively and followed up.Results:After follow-up, 27 of the 32 patients were diagnosed as ADEM and 4 were diagnosed as multiphasic disseminated encephalomyelitis(MDEM), 1 was diagnosed as ADEM followed by optic neuritis(ADEM-ON).Among the 27 patients diagnosed with ADEM, most of them were girls, 3~8 years old, had a history of infection before onset, occurred in summer and autumn.Common clinical symptoms included disturbance of consciousness or mental and behavior disorders(27/27, 100.0%), fever(13/27, 48.1%), paralysis(13/27, 48.1%), abnormal defecation(7/27, 25.9%), decreased vision(7/27, 25.9%)and so on.Brain MRI mainly involved subcortical white matter(20/27, 74.1%), cerebellum(10/27, 37.0%), deep nuclei such as thalamus and basal ganglia(7/27, 25.9%)and brainstem(3/27, 11.1%).In 10 cases, myelin oligodendrocyte glycoprotein(MOG)antibody tests showed positive results in 3(30.0%)and negative results in 7(70.0%).There were no significant differences in gender, age, history of infection before onset, season of onset, clinical symptoms, peripheral WBC, CRP, erythrocyte sedimentation rate, levels of WBC and protein in cerebrospinal fluid, electroencephalogram, brain and spinal cord MRI, treatment and prognosis between the MOG antibody positive and negative children(all P>0.05).16 cases (59.3%)were recovery completely, 11 cases (40.7%)were not, the rate of the infection before onset of the former was higher than the latter( P<0.05).27 cases (84.4%)had monophasic course and 5 cases (15.6%)had non-monophasic course, more of the nonmonophasic children′s brain MRI show multiple abnormal signals in the brain than the monophasic children( P<0.05). Conclusion:Children with first diagnosed ADEM require long-term clinical follow-up, and brain MRI show a higher risk of recurrence of multiple abnormal signals in the brain.The prognosis of ADEM children with a history of infection before onset is relatively good.

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is one of inflammatory demyelinating disorders of the central nervous system.Due to the diverse and atypical clinical manifestations, positive rate of current detection methods is not high, and early diagnosis is difficult.This review aims to elucidate the research progress of the epidemiology, pathogenesis, clinical characteristics, diagnostic criteria, biological markers, treatment and prognosis of MOGAD, in order to improve the understanding of MOGAD for clinicians, so as to identify, treat and reduce the recurrence of MOGAD as early as possible.
