Flowering and bolting are important agronomic traits in cruciferous crops such as Brassica juncea. Timely flowering can ensure the crop organ yield and quality, as well as seed propagation. The WRKY family plays an important role in regulating plant bolting and flowering, while the function and mechanism of WRKY12 in B. juncea remain unknown. To explore its function and mechanism in bolting and flowering of B. juncea, we cloned and characterized the BjuWRKY12 gene in B. juncea and found that its expression levels were significantly higher in flowers and inflorescences than in leaves. BjuWRKY12 belonged to the Ⅱc subfamily of the WRKY family, and subcellular localization indicated that the protein was located in the nucleus. Ectopic overexpression of BjuWRKY12 in transgenic lines promoted bolting and flowering, leading to significant increases in the expression levels of flowering integrators SOC1 and FUL. Furthermore, yeast one-hybrid and dual luciferase reporter system assays confirmed that BjuWRKY12 directly bound to the promoters of BjuSOC1 and BjuFUL, undergoing protein-DNA interactions. This discovery gives new insights into the regulation network and molecular mechanisms of BjuWRKY12, laying a theoretical foundation for the breeding of high-yield and high-quality varieties of B. juncea.

OBJECTIVE To provide a reference for the adjustment of antibacterial drug regimens， identification of adverse reactions， and personalized pharmaceutical care for patients with bullous pemphigoid and pulmonary aspergillosis combined with disseminated Nocardia farcinica infection. METHODS Clinical pharmacists participated in the entire treatment process of a patient with bullous pemphigoid and pulmonary aspergillosis combined with disseminated N. farcinica infection. Evidence-based medicine was used to assist in the selection of an initial combined drug regimen against nocardiosis， and timely communication with the microbiology laboratory to provide early antimicrobial susceptibility data. When the patient exhibited epilepsy， the suspected drugs were identified， and it was reminded that imipenem-cilastatin sodium could affect the efficacy of valproic acid. It was suggested to replace valproic acid with levetiracetam for anti-epileptic treatment and to discontinue imipenem-cilastatin sodium. During treatment， it was recommended to monitor the blood concentrations of voriconazole and linezolid， and assist in adjusting the dosage promptly based on the monitoring results. RESULTS The physicians accepted the recommendations of the clinical pharmacists. The patient’s condition improved， and they were discharged with medication. CONCLUSIONS Based on evidence-based medical evidence， antimicrobial susceptibility test results， and blood concentration monitoring data， clinical pharmacists assist clinicians in selecting a sensitive anti-infective regimen for the patient， identifying adverse reactions， adjusting the treatment regimen and providing full-course medication monitoring to ensure the safety and efficacy of clinical drug therapy.

Objective To explore the key molecular targets and possible mechanisms of Aidi injection in the treatment of ovarian cancer using network pharmacology and cell experiments.Methods TCMSP database was used to screen the active ingredients and tar-gets of Aidi injection,and the abnormal expressed genes of ovarian cancer were screened,and the possible targets of Aidi injection in o-varian cancer were obtained after intersection analysis.Then,protein-protein interaction analysis,drug-compact-target network con-struction and enrichment analysis of possible targets were performed.The target was further screened,and the key genes related to the prognosis of ovarian cancer were experimentally verified.After treated with 50mg/ml Aidi injection,the cell proliferation ability was ob-served by CCK-8 assay,and the expression of core target genes was detected by real-time quantitative polymerase chain reaction.Results A total of 13 possible targets of Aidi injection in ovarian cancer were screened.These targets were mainly enriched in signaling pathways closely related to the occurrence and development of tumors,such as apoptosis,platinum resistance and interleukin-17.Among the 13 genes,claudin 4(CLDN4),secretory leukocyte peptidase inhibitor(SLPI)and baculoviral IAP repeat containing 5(BIRC5)were associated with the prognosis of ovarian cancer.Cell experiments showed that Aidi injection significantly inhibited the proliferation of ovari-an cancer cell,promoted the expression of BIRC5,a protective target of ovarian cancer,while significantly decreased the levels of ovarian cancer risk factors CLDN4 and SLPI.Conclusion Aidi injection may achieve multi-component,multi-target and multi-pathway anti-ovarian cancer and combination chemotherapy by affecting the expression of CLDN4,SLPI and BIRC5.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

The process of embryo implantation is a multifaceted and intricate dynamic event that includes the development of endometrial receptivity, embryo localization, adhesion, and invasion. Adhesion molecules, acting as crucial mediators of communication between cells or between cells and the extracellular matrix, are essential for the maintenance of endometrial receptivity and the regulation of embryo localization, adhesion, and invasion. However, the mechanisms by which adhesion molecules of maternal and embryo are organized to regulate key events in the peri-implantation period have yet to be fully explored. Based on recent research findings, this review provides a summary of the functions of different adhesion molecules at the maternal-fetal interface and their potential regulatory mechanisms according to the key progress of embryo implantation. In particular, we discussed the interactions between decidual immune cells and other cells mediated by adhesion molecules during the invasion process, which will provide novel perspectives into the role of adhesion molecule dysfunction in contributing to implantation failure.

OBJECTIVE To explore the construction of mind map by clinical pharmacists for the consultation of pulmonary nocardiosis and its application in clinical practice， and to provide reference for promoting the correct selection of nocardiosis treatment drugs in clinical practice and ensuring drug safety and efficacy. METHODS A total of 7 patients with Nocardia pulmonary infection from January 2017 to April 2022 in our hospital were collected. Based on evidence-based medicine， a consultation mind map （mainly including understanding the medical history， identifying infectious bacteria， identifying risk factors， developing treatment plans， and conducting evaluations） was constructed to address the difficulties of large differences in drug sensitivity among different strains of Nocardia and numerous adverse reactions of Compound sulfamethoxazole as a first-line drug. The treatment plan was developed for 7 patients with pulmonary nocardiosis， and whole-process pharmaceutical care was provided. RESULTS Combined with the mind map， different antibiotic combination regimens were given according to the drug sensitivity results of Nocardia， the different species of Nocardia， and the patient’s allergy history. Among them， 4 cases were treated with imipenem cilastatin， the patients receiving Compound sulfamethoxazole and linezolid for a long time were given full pharmaceutical care， and the adverse drug reactions were timely treated.CONCLUSIONS Clinical pharmacists apply the consultation mind map of pulmonary nocardiosis to the treatment of inpatients， take advantage of pharmacy， participate in clinical drug therapy， and really play a role in the clinical treatment team so as to promote rational drug use.

We report a case of type A insulin resistance syndrome. A 16-year-old girl with BMI of 19.1 kg/m 2 presented with primary amenorrhea and hyperglycemia for two years. Baseline HbA 1C was 10.8%, along with severe hyperinsulinemia, increased total testosterone and free androgen index(FAI). Ultrasonography showed polycystic ovaries. Next generation sequencing identified a novel and de novo heterozygous missense mutation of Trp1220Gly in the insulin receptor gene. Short-term intensive insulin pump treatment was initiated, followed by insulin glargine, pioglitazone and acarbose combination regiment. Fasting blood glucose and insulin levels decreased significantly, but post-load hyperglycemia and hyperinsulinemia remained unsatisfactory. HbA 1C dropped to 7.6% at 1-year follow up. Patients with polycystic ovarian syndrome who are adolescent-onset and with lean body type should be taken into account of type A insulin resistance syndrome. Currently, there is no standardized treatment protocol, and therapy should be individualized based on the specific gene mutation of each patient.
