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.

BACKGROUND: The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results. OBJECTIVE: To identify factors and their impact on the treatment effect of acupuncture in different outcomes. METHODS: Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects. RESULTS: The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01). CONCLUSIONS High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

AIM To optimize the processing technology of red Notoginseng Radix et Rhizoma and evaluate its blood tonifying activity.METHODS On the basis of a single factor experiment,with steaming temperature,steaming time,drying temperature,and drying time as influencing factors,the total contents of notoginsenoside R1,ginsenoside Rg1,Rb1,Rk3,Rh4,and 20(R)-ginsenoside Rg3 as evaluation indicators,Box-Behnken response surface method ology was used to optimize the processing technology.Upon the anemic mouse models jointly induced by 1-acetyl-2-phenylhydrazine(APH)and cyclophosphamide(CTX),the investigation of the blood tonifying activity of red Notoginseng Radix et Rhizoma was carried out in contrast to that of the steamed Notoginseng Radix et Rhizoma.RESULTS The optimal conditions,contributing saponin content of 8.326%and RSD of 0.087%,were determined as follows:steaming temperature of 130℃,steaming time of 4 hours,drying temperature of 60℃,and drying time of 48 h.The pharmacological activity revealed that the different processing techniques were responsible for the different blood enriching activity of notoginseng,with red Notoginseng Radix et Rhizoma displaying a better efficacy than that of steamed Notoginseng Radix et Rhizoma.CONCLUSION This stable and feasible method can be used to control the production of red Notoginseng Radix et Rhizoma.

Objective To investigate the effect of Jiaotaiwan on brain insulin-PI3K/AKT pathway in a mouse model of Alzheimer's disease(AD).Methods Fifty 3-month-old male APP/PS1 double transgenic mice were randomized into AD model group,low-,medium-and high-dose Jiaotaiwan treatment groups,and donepezil treatment group.Cognitive functions of the mice were assessed using water maze and open field tests,and neuronal pathologies were observed with HE staining and Nissl staining;immunohistochemistry was used to detect amyloid Aβ deposition in the brain.Fasting serum insulin levels of the mice were measured,and the expressions of Aβ42,insulin-PI3K/AKT pathway components and downstream glucose transporters in the brain tissue were detected with RT-qPCR and Western blotting.Results The AD mouse models exhibited obvious impairment of learning and memory abilities,significantly reduced hippocampal neurons,and obvious Aβ amyloid plaques in the brain tissue with increased Aβ42 protein expression(P<0.05)and insulin resistance index,decreased hippocampal PI3K expressions,lowered expressions of AKT and InR,reduced expressions of GLUT1,GLUT3,and GLUT4,and increased expression of GSK3β in both the hippocampus and cortex.Treatment with Jiaotaiwan and donepezil both effectively improved memory ability of the mouse models,increased the number of hippocampal neurons,reduced Aβ amyloid plaques and increased the expressions of PI3K,AKT,InR,GLUT1,GLUT3 and GLUT4 in the hippocampus and cortex.Conclusion Jiaotaiwan improves learning and memory abilities of APP/PS1 double transgenic mice and delay the development of AD by activating the PI3K/AKT pathway and regulating the expression levels of its downstream GLUTs in the brain.

In this study,nine hybridoma cells secreting monoclonal antibodies against deltamethrin were prepared,and the monoclonal antibody 4D4E11 with best sensitivity was selected to develop indirect enzyme-linked immunosorbent assay (ic-ELISA) and gold nanoparticle-based lateral flow immunoassay (LFIA) for detection of deltamethrin. The optimal working buffer for ic-ELISA was 0.01 mol/L phosphate buffer (pH 7.4) containing 0.2 mol/L NaCl and 20％ methanol,while 0.01 mol/L phosphate buffer (pH 7.4) containing 1 mol/L NaCl,5‰Tween-20 and 10％methanol for LFIA. Under the optimal conditions,the half inhibition concentration (IC50) and limit of detection (IC10) of ic-ELISA were 10.60 ng/mL and 1.43 ng/mL respectively,and the limit of detection of the developed LFIA was 0.5μg/mL. The developed ic-ELISA and LFIA showed no cross-reactivities (CRs) with eight kinds of analogues of deltamethrin,which indicated the excellent specificity of proposed immunoassays. The average recoveries of the ic-ELISA in spiked tomato,cabbage and lettuce samples were 79.8％-92.6％with relative standard deviations of 0.8％-5.5％. The detection results of LFIA were consistent with the spiked concentrations in the range of 1-5 mg/kg. Meanwhile,the results of ic-ELISA and LFIA showed close correlation with high performance liquid chromatography (HPLC) in the test of blind lettuce samples. The experimental results demonstrated that the two immunoassays proposed here were suitable for rapid detection of deltamethrin with high sensitivity and high accuracy.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

In recent years,the prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKP)infection has become a global public health issue.Ceftazidime/avibactam(CAZ/AVI)has been approved as a novel antimicrobial agent for the treatment of healthcare-associated pneumonia/ventilator-associated pneumonia,bloodstream infection,infection after kidney transplantation,and severe infection combined with liver cirrhosis.However,the use of CAZ/AVI has also led to the emergence of drug-resistant strains.The major mechanisms of drug-resistance include over-expression of blaKPC gene,mutation of β-lactamase and amino acids at key sites,changes in cell permeability caused by loss of membrane porin,and over-expression of efflux pump.This article reviews the research progress of CAZ/AVI in the treatment of CRKP infection,providing reference for clinical diagnosis and treatment.

Objective To analyze the distribution and antimicrobial resistance of pathogens from wounds of burned patients,providing reference for the rational use of antimicrobial agents and healthcare-associated infection(HAI)prevention and control.Methods Clinical data of burned patients admitted to a tertiary first-class hospital from Ja-nuary 2020 to December 2022 were analyzed retrospectively,pathogens in the wound was cultured,identified,and performed antimicrobial susceptibility analysis.Results From 2020 to 2022,a total of 588 burned patients were ad-mitted,734 strains of pathogens were detected,including 415 strains(56.54％)of Gram-negative bacteria,306 strains(41.69％)of Gram-positive bacteria,and 13(1.77％)strains of fungi.The top 5 pathogens were Staphy-lococcus aureus,Escherichia coli,Pseudomonas aeruginosa,Klebsiella pneumoniae,and Enterobacter cloacae.Staphylococcus aureus had higher resistance rates(93.02％-97.37％)to penicillin G,resistance rate to oxacillin increased from 11.63％to 21.92％.Pseudomonas aeruginosa mainly exhibited resistance to ticarcillin/clavulanic acid,aztreonam,and levofloxacin,resistance rates to imipenem and meropenem were 15.00％-38.10％and 10.00％-33.33％,respectively.Susceptibility of Enterobacterales bacteria to cephalosporins enhanced with the increased of cephalosporin generations,and exhibited higher resistance to commonly used antimicrobial agents.Conclusion Over the past three years,there has been no significant change in the detection of major pathogens and antimicrobial resistance in wounds of burned patients in this hospital.Antimicrobial resistance of Staphylococcus aureus and En-terobacterales is relatively severe,and it is necessary to carry out surveillance on pathogens from burn wounds in corresponding areas.

This study was aimed at comparing performance differences among three metagenomic sequencing platforms,MGISEQ-2000,Illumina NextSeq 2000,and Ion GeneStudio S5 Plus,to optimize the sequencing process for trace samples.The three sequencing platforms were used to perform high-throughput sequencing on DNA standards and simulated samples.Through analysis of the quality of raw data and microbial detection capabilities,systematic differences among platforms were compared.The sequencing results were optimized for trace samples by incorporation of exogenous nucleic acids during the li-brary preparation process.In terms of data output per batch and base quality,MGISEQ-2000 surpassed the other two plat-forms.Illumina NextSeq 2000 had the lowest proportion of duplicate reads,whereas Ion GeneStudio S5 Plus had the highest proportion,and significant differences were observed across platforms(P＜0.001).In sequencing uniformity,MGISEQ-2000 and Illumina NextSeq 2000 were superior to Ion GeneStudio S5 Plus.MGISEQ-2000 provided a substantial advantage in microbial detection capability(P＜0.001),but the advantage diminished with decreasing bacterial fluid concentration.Ion GeneStudio S5 Plus had the shortest duration for single-batch sequencing.Moreo-ver,for trace samples with DNA content ≤0.05 ng,the experi-mental group(with added exogenous nucleic acids)achieved a higher number of reads than the control group(without exogenous nucleic acids),with a 11.09±8.03 fold increase.In conclu-sion,the different sequencing platforms each had advantages and disadvantages,thus allowing researchers to choose the appro-priate platform according to specific needs.Furthermore,the addition of exogenous nucleic acids improved the microorganism detection efficiency,and provided better support for subsequent diagnosis and evaluation of results.
