Antibody-drug conjugates （ADCs） are a novel class of anti-tumor agents composed of a targeted monoclonal antibody， a cytotoxic drug， and a linker connecting the two. They combine the high specificity of antibodies with the potent cytotoxicity of chemotherapeutic agents. Triple-negative breast cancer （TNBC） is characterized by high aggressiveness， elevated risks of recurrence and metastasis， and poor prognosis， largely due to the lack of effective therapeutic targets. This review summarizes the research progress of ADCs in the treatment of TNBC. It has been found that ADCs targeting human epidermal growth factor receptor 2 （such as trastuzumab deruxtecan）， trophoblast cell surface antigen 2 （such as sacituzumab govitecan and datopotamab deruxtecan）， zinc transporter LIV-1 （such as ladiratuzumab vedotin）， HER-3 （such as patritumab deruxtecan）， epidermal growth factor receptor （such as AVID100）， and glycoprotein non-metastatic melanoma protein B （such as glembatumumab vedotin） have all demonstrated promising therapeutic effects against TNBC. Despite challenges including acquired resistance and treatment-related toxicities， ADCs are undoubtedly reshaping the therapeutic landscape for TNBC and are expected to occupy a more central position in TNBC treatment in the future.

Objective: Patients with atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI) are classified as very-high-risk individuals in cardiovascular disease (CVD) risk stratification. The distribution pattern of traditional Chinese medicine (TCM) syndromes in this patient population, as well as its association with blood lipid profiles and clinical prognosis, remains unclear. The present prospective cohort study aims to investigate these correlations, thereby providing insights to enrich the research fields. Methods: We enrolled consecutive patients with ASCVD who underwent PCI at the Integrated Cardiology Unit of China-Japan Friendship Hospital between September 1, 2020 and December 31, 2022. Demographics and clinical characteristics, signs and symptoms defining each TCM syndrome, and fasting venous blood samples were collected at baseline and follow up or upon major adverse cardiovascular events (MACEs). We analyzed the correlation between TCM syndromes, blood lipid profiles, and MACEs, and developed a new joint prognostic model incorporating both TCM syndromes and blood lipids using logistic regression. The analyses were based on detailed baseline and one-year follow-up data. Results: A per-protocol analysis was performed on 586 patients with complete data ultimately. During the one-year follow-up, 174 patients (29.69%) experienced a MACE. We performed statistical analyses on comorbidities, medication, and biochemical indicators across groups defined by TCM syndrome differentiation. When comparing different TCM syndromes, no significant differences were found in age, body mass index (BMI), history of revascularization, comorbidities, family history of CVD, smoking or drinking, or statin intensity (P > 0.05). Patients with intertwined phlegm and blood stasis syndrome exhibited significantly higher levels of total cholesterol (TC, 5.27 ± 1.18 mmol/L, P < 0.001), triglyceride (TG, 1.96 ± 1.33 mmol/L, P = 0.008), low-density lipoprotein cholesterol (LDL-C, 3.35 ± 0.79 mmol/L, P < 0.001), and high-density lipoprotein cholesterol (HDL-C, 1.24 ± 0.81 mmol/L, P < 0.001) compared with those with other TCM syndromes combined. A multivariable logistic regression model was constructed to predict MACEs. The model included TCM syndrome type [with intertwined phlegm and blood stasis as a predictor, adjusted odds ratio (OR) = 1.413, 95% confidence interval (CI): 0.517 – 3.864, P = 0.501], age (adjusted OR = 0.97, 95% CI: 0.955 – 1.001, P = 0.057), male gender (adjusted OR = 0.698, 95% CI: 0.416 – 1.170, P = 0.173), TC (adjusted OR = 1.004, 95% CI: 0.513 – 1.965, P = 0.990), and LDL-C (adjusted OR = 5.825, 95% CI: 2.214 – 15.326, P < 0.001). This model demonstrated good discriminatory ability for MACEs in post-PCI ASCVD patients [the area under the receiver operating characteristic (ROC) curve (AUC) = 0.865, 95% CI: 0.816 – 0.914]. Conclusion The intertwined phlegm and blood stasis TCM syndrome is associated with a distinct atherogenic lipid profile characterized by elevated levels of TC and LDL-C. The prognostic model that incorporates this TCM syndrome type along with conventional lipid parameters (TC and LDL-C) shows good discriminatory ability for predicting MACEs in ASCVD patients after PCI, underscoring the potential clinical utility of integrating TCM syndrome differentiation into CVD risk assessment.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics （ 2026 edition ） in response to the challenges faced by such clinics in China， including uneven development， large discrepancies in service specifications， insufficient patient awareness， and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association， the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association， and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association， a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research， current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections： definition and connotation of pharmacist-managed clinics， establishment requirements， implementation and management， post competency， and practical research. Firstly， the definition and connotation included three operational forms of pharmacist-managed clinics （independent mode， physician-pharmacist joint mode， and online pharmacist-managed clinic mode） and classified service modes （specialty-specific， drug-specific， and disease-specific pharmacist-managed clinics）. The establishment requirements were further refined， covering system construction （pharmaceutical service management system， quality control and assessment mechanism）， personnel qualifications （professional credentials， continuing education and professional training， etc）， service recipients， as well as service venues and facilities. Subsequently， the implementation and management of pharmacist-managed clinics were proposed， involving service procedures， intervention measures， documentation and records， patient education and follow-up， humanistic care， as well as risk management and quality control. Finally， post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics， as well as the suggestions on teaching methods； practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment， management， teaching， and research， fill the guideline gap in this field， and can promote the high-quality development of pharmacist-managed clinics.

ObjectiveTo investigate whether intestinal deficiency of lanosterol synthase （LSS）， a key enzyme in cholesterol synthesis， influences the progression of metabolic dysfunction-associated steatotic liver disease （MASLD） by regulating intestinal cholesterol absorption and immune response. MethodsLSS heterozygous knockout （LSS^+/-） mice and wild-type （WT） controls were generated using CRISPR/Cas9 technology and fed either a high-fat diet （HFD） or regular chow （CHOW）. The model was validated by genotyping. Hepatic steatosis was assessed by HE and oil red O staining. Immunohistochemistry was used to detect the localization and expression of NPC1L1 and CD36 proteins in the intestine. Western blot analysis was performed to measure JNK phosphorylation and TLR4 protein levels in intestinal tissues. Real-time quantitative polymerase chain reaction （qPCR） was employed to examine the mRNA expression of TLR4 and IL-6. ResultsLSS^+/- mice were successfully validated by genotyping and reduced intestinal LSS protein expression. HE and oil red O staining of liver sections showed that， compared with WT mice fed a CHOW diet， WT mice fed a HFD exhibited a marked increase in hepatic lipid vacuoles. In contrast， compared with HFD-fed WT mice， HFD-fed LSS^+/- mice displayed significantly attenuated hepatic lipid deposition and reduced serum ALT levels （P<0.05）. Immunohistochemical analysis revealed that， compared with WT mice， the expression of the cholesterol absorption protein NPC1L1 in the intestinal villi of LSS^+/- mice was downregulated under both CHOW and HFD conditions （P_HFD<0.001）. Conversely， the expression of the fatty acid transporter CD36 was upregulated in the intestines of LSS^+/- mice （P_CHOW<0.05， P_HFD<0.01）. Western blot analysis demonstrated that， compared with WT mice， TLR4 protein expression in the intestines of LSS^+/- mice significantly increased under both CHOW and HFD conditions （both P<0.05）. JNK phosphorylation level was significantly elevated in LSS^+/- mice under CHOW condition （both P<0.05）. Under HFD condition， total JNK protein expression increased， but its phosphorylation level showed no significant change. qPCR analysis showed that， compared with WT mice， the mRNA levels of TLR4 （P_CHOW<0.01， P_HFD<0.000 1） and IL-6 （P_CHOW<0.001， P_HFD<0.01） were significantly upregulated in the intestines of LSS^+/-mice. ConclusionLSS deficiency counteracts hepatic lipid deposition by orchestrating a synergistic reprogramming involving restricted intestinal cholesterol absorption， enhanced fatty acid utilization， and activation of immune pathways， suggesting intestinal LSS as a potential therapeutic target of MASLD.

The experts reached a consensus on the comprehensiveness and practicability of the index system, aiming to lay a solid foundation for construction of China's schistosomiasis prevention and control early warning system.

Neurotropic viruses are a group of viruses that highly sensitive to central nervous system.As the first line of defense against pathogen invasion,the activation of pathogen recognition receptor signaling network in innate immune system plays a"double-edged"role in the process of neurotropic virus infection,which has both antiviral effect and may aggravate virus infection under certain circumstances.This article reviews the research progress on dual roles of pathogen recognition receptors in neurotropic virus infection.

Objective:To analyze the relationship between folate and thyroid antibody in early pregnancy and adverse pregnancy outcome in pregnant women with hypothyroidism during pregnancy.Methods:The data of 97 pregnant women with hypothyroidism from Jul. 2020 to Mar. 2023 in the Obstetrics Department of Liaocheng Second People’s Hospital were retrospectively analyzed. The levels of folate, thyroglobulin antibody (TGAb) and thyroid peroxidase antibody (TPOAb) were detected in the first trimester. According to whether adverse pregnancy outcome occurred in pregnant women with hypothyroidism during pregnancy, they were divided into occurrence group and non-occurrence group. The clinical data of the occurrence group and the non-occurrence group were compared. Logistic regression was used to analyze the influencing factors of adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy, and receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of folic acid, TGAb, TPOAb and their combination on adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy.Results:Among 97 pregnant women, the incidence of adverse pregnancy outcome was 14.43% (14/97) .The folate level in the occurrence group was lower than non-occurrence group ( P<0.05) , and the TGAb and TPOAb levels in the occurrence group were higher than non-occurrence group ( P<0.05) . The occurrence group with alanine aminotransferase (ALT) , glutamine transpeptidase (GGT) and aspartate aminotransferase (AST) were all higher than non-occurrence group ( P<0.05) .The folate, TGAb, and TPOAb levels were factors influencing adverse pregnancy outcomes in pregnant women with hypothyroidism ( P<0.05) . The area under the curve (AUC) values of folate, TGAb, TPOAb and their combined prediction of adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy were 0.804, 0.843, 0.799, 0.909 ( P<0.05) , while the combined three with AUC values were higher ( P<0.05) . Conclusion:The folate, TGAb and TPOAb levels in early pregnancy can be used to evaluate adverse pregnancy outcomes in hypothyroidism pregnant women, and the combination of the three has a higher evaluation value.

BACKGROUND:Developed by the esteemed Chinese medicine master Wei Guikang,Tongan Decoction has proven highly effective in treating knee osteoarthritis.However,the mechanism of action is yet unclear.OBJECTIVE:To elucidate how Tongan Decoction modulates synovial macrophage polarization as a therapeutic strategy for knee osteoarthritis in a rat model.METHODS:(1)We employed high-throughput microRNA sequencing and polymerase chain reaction to analyze the differentially expressed miRNA in synovial macrophages of normal and knee osteoarthritis rats.Predicted target genes of miR-27a were identified using bioinformatics databases,with subsequent validation through luciferase assays.A total of 68 Sprague-Dawley rats were randomly divided into normal control group(n=16),model group(n=16),miR-27a overexpression group(n=12),Tongan Decoction group(n=12),and Tongan Decoction+miR-27a inhibition group(n=12).The miR-27a overexpression group and the Tongan Decoction+miR-27a inhibition group were injected with miR-27a mimic and miR-27a inhibitor in the right knee joint cavity,respectively,once daily for 5 continuous days.On the 15th day after modeling,the Tongan Decoction group and the Tongan Decoction+miR-27a inhibition group were given Tongan Decoction by gastric lavage,and the other three groups were given saline by gastric lavage,once daily for 14 continuous days.After administration,behavioral tests,X-rays,hematoxylin-eosin staining of synovial and cartilage tissues of the knee joint and immunofluorescence staining of synovial tissues of the knee joint,RT-PCR,and Western blot were performed.RESULTS AND CONCLUSION:High-throughput sequencing of miRNA showed low expression of miR-27a in synovial tissues of rats with knee osteoarthritis.The target gene of miR-27a was nuclear factor κB,and luciferase assay showed that the two could bind to each other.Behavioral assays showed that miR-27a overexpression or Tongan Decoction alleviated joint dysfunction in rats with knee osteoarthritis,and miR-27a inhibition antagonized the effect of Tongan Decoction.X-ray films and hematoxylin-eosin staining showed that miR-27a overexpression or Tongan Decoction reduced the degree of knee osteoarthritis and miR-27a inhibition weakened the therapeutic effect of Tongan Decoction.The results of RT-PCR and western blot assay showed that compared with the normal control group,the expression of interleukin 10 was reduced in the model group(P＜0.05),and the expression of matrix metalloproteinase 13,interleukin 1β,and nuclear factor κB was elevated in the model group(P＜0.05).miR-27a overexpression or Tongan Decoction could differently reverse the changes in the above-mentioned indexes,while miR-27a inhibition weakened the effect of Tongan Decoction.Immunofluorescence staining results showed that CD86 protein expression in the model group was higher than that in the normal control group(P＜0.05),and CD206 protein expression was lower than that in the normal control group(P＜0.05);miR-27a overexpression group and Tongan Decoction had lower CD86 protein expression than that in the model group(P＜0.05),and higher CD206 protein expression than that in the model group(P＜0.05);in the Tongan Decoction+miR-27a inhibition group,CD86 protein expression was higher(P＜0.05)and CD206 protein expression was lower than that in the Tongan Decoction group(P＜0.05).Tongan Decoction mitigates knee osteoarthritis by upregulating miR-27a expression and suppressing nuclear factor κB activity,which improves knee joint function and further treats knee osteoarthritis.

Objective:To investigate the effect of olanzapine (OLZ) on the differentially-expressed circRNAs in prefrontal cortex of schizophrenia mouse models and predict the target genes.Methods:SPF grade C57BL/6 mice, 7~8 weeks-old, 20 male mice and 45 female mice were recruited and breeded offspring.Forty-four double-stimulation induced schizophrenia-like mouse models, the offspring mice exposed to dual stress were divided into the schizophrenia group(SZ group, n=23) and the olanzapine intervention group (SZ+ OLZ group, n=21), while the mice raised under normal conditions served as the control group (NC group, n=22). Whole transcriptome sequencing was used to sequence the expression level of RNAs from the prefrontal cortex of the mice. RT-qPCR was applied to verify the differentially-expressed circRNAs, then the target genes of miRNAs which have binding site to verified circRNAs were predicted. Results:RNA-seq results showed that there were 137 differentially-expressed circRNAs compared with NC group, 62 were significantly high-expressed and 75 were low-expressed. circRNA_06886 showed significant low-expressed in SZ group compared with NC group( Z=-3.259, P<0.01), and significant high-expressed in SZ+ OLZ group compared with SZ group( Z=-4.765, P<0.01). Bioinformatics analysis of miRNA target genes showed that the target genes were involved in the pathways related to neural pathways such as dopamine, glutamate and MAPK signaling pathways. Conclusions:There are differentially expressed circRNAs in the prefrontal cortex of schizophrenia mouse models, and circRNA_06886 is low-expressed in the prefrontal cortex of schizophrenia mice, Camk2b-201 and Plcb1-003 are the potential genes of circRNA_06886 involved in the regulation of schizophrenia pathogenesis by dopamine pathway.
