ObjectiveTo explore the effect of Polygonati Odorati Rhizoma polysaccharides on hyperlipidemia in mice by modulating the gut microbiota. MethodsNinety male C57BL/6J mice were randomized into the following groups (n=15): control, model, simvastatin, low- (100 mg·kg-1), medium- (200 mg·kg-1), and high-dose (400 mg·kg-1) Polygonati Odorati Rhizoma polysaccharides groups. Other groups except the control group were fed with a high-fat diet for the modeling of hyperlipidemia, and drug interventions lasted for 12 weeks. Serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured by an automatic biochemical analyzer. The pathological changes in the liver and epididymal fat were observed by hematoxylin-eosin staining, and lipid accumulation in the liver was assessed by oil red O staining. The gut microbiota was analyzed by 16S rRNA gene sequencing. ResultsCompared with the control group, the model group exhibited an increase in body weight (P<0.01), along with marked elevations in serum levels of TC, TG, and LDL-C (P<0.05,P<0.01). Furthermore, the model group showcased increase in the liver index and epididymal fat coefficient (P<0.05), increased liver fat accumulation, enlargement of adipocytes in the epididymal fat, decreases in both alpha and beta diversity of the gut microbiota, and an increase in the relative abundance of Allobaculum (P<0.01). Compared with the model group, Polygonati Odorati Rhizoma polysaccharides suppressed the increase in body weight (P<0.01), lowered the serum levels of TC, TG, and LDL-C (P<0.05,P<0.01), reduced the liver index and epididymal fat coefficient (P<0.05), alleviated liver fat accumulation, and decreased the size of adipocytes in the epididymal fat. Furthermore, it enhanced the alpha and beta diversity of the gut microbiota in mice, reduced the relative abundance of Allobaculum, Erysipelotrichaceae, and Clostridium (P<0.01), and increased the relative abundance of Akkermansia and Blautia (P<0.01). ConclusionPolygonati Odorati Rhizoma polysaccharides can ameliorate hyperlipidemia induced by a high-fat diet in mice by regulating the diversity and composition of the gut microbiota.

Triple-negative breast cancer is therapeutically challenging due to the low expression of tumor markers and 'cold' tumor immunosuppressive microenvironment. Here, we present a dual-targeting peptide-drug conjugate (PDC) for tumor inhibition. Our PDC efficiently and selectively delivers cytotoxic Monomethyl Auristatin E (MMAE) into tumor cells via C-X-C chemokine receptor type 4 (CXCR4) and folate receptor 1 (FOLR1) for synergistic inhibition of growth and metastasis. Our results show that the dual-targeting PDC has potent antitumor activity in cultured human cells and several murine transplanted tumor models without apparent toxicity. The combination of dual-targeting PDC and radiotherapy modulates the tumor immunosuppressive microenvironment by increasing CD8+ T cell infiltration and attenuating the proportion of myeloid-derived suppressor and regulatory T cells. Therefore, our dual-targeting PDC represents a promising new strategy for cancer therapy that rebalances the immune system and promotes tumor regression.

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.

AIM: To evaluate the effect of capsular tension ring(CTR)on the stability and accuracy of Barrett universal Ⅱ intraocular lens(IOL)calculation formula in patients with high myopia and cataract.METHODS:Prospective study. A total of 40 cases(80 eyes)of high myopia and cataract that visited our hospital from January to June 2022 were selected. The patients were divided into CTR group and blank group by random number table method, with 40 eyes in each group. All patients were measured by IOL Master, and the actual implanted IOL power and predicted postoperative power were calculated according to Barrett universal Ⅱ formula. The uncorrected visual acuity(UCVA)and best corrected visual acuity(BCVA)at 6 mo after surgery were recorded, and the mean absolute error(MAE)was compared at 6 mo after surgery. Furthermore, the stability of postoperative refractive status and the relationship between the predicted postoperative diopter and CTR were evaluated.RESULTS:The UCVA and BCVA of the two groups were improved at 6 mo after operation(P>0.05), and there was no significant difference in UCVA and BCVA between the two groups at each time point(all P>0.05). After the implantation of IOL in 80 eyes based on the Barrett universal Ⅱ formula, the predicted postoperative diopter was -2.01±0.71 D, the actual postoperative diopter was -1.64±0.88 D, and the MAE was 0.37±0.98 D in the CTR group; in the blank group, the predicted diopter was -2.12±0.64 D, the actual diopter was -1.54±0.88 D, and the MAE was 0.58±0.31 D. The difference between the two groups was statistically significant(P<0.05). According to the axial length, CTR implantation can effectively reduce refractive error for any axial length(P>0.05). With the grouth of axial length, the MAE value increased. The postoperative MAE value of patients with axial length ≥30 mm was statistically different between the two groups(P<0.05).The proportion of hyperopic drift was 18%(7/40)in the CTR group and 30%(12/40)in the blank group, respectively, with a significant difference between the two groups(P<0.05).CONCLUSION: For patients with high myopia and cataract, the Barrett universal Ⅱ formula has high accuracy in predicting postoperative diopter. Intraoperative implantation of CTR can not only maintain the shape of the capsule bag, effectively prevent the intraoperative rupture of the suspensory ligament of the lens and make the IOL more neutral, but also is conducive to the early stability of postoperative diopter of cataract patients. It also provides more stable refractive results and reduces refractive drift. For myopic patients considering CTR implantation, it is recommended to increase the preoperative reserve diopter of -0.50 D to achieve the ideal refractive state.

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.
