The concept of "spirit" in traditional Chinese medicine （TCM） aligns closely with "the liver governs the designing of strategy". By exploring the relationship between the liver and executive function decline， it is proposed that prolonged liver constraint leads to indecisiveness in strategy designing， which is the initiating factor for executive function decline； liver blood deficiency causes difficulties in executing strategy， which forms an essential foundation for the progression of executive function decline； obstruction in the "liver-du mai-brain" pathway leads to unclear strategy designing， which accelerates executive function decline. This relationship is examined from the perspectives of TCM， modern medicine， and cognitive psychology， aiming to provide insights into addressing executive function decline through treatments focused on the liver.

Traditional Chinese medicine （TCM） compound prescriptions serve as crucial practical embodiments of TCM theoretical frameworks， characterized by their complex multi-component composition and multi-target interactions. The research on the material basis of their pharmacological effects has gradually become the key to promoting the modernization of TCM. In recent years， new ideas and theories regarding the research on pharmacodynamic substance basis of TCM compound prescriptions have been continuously proposed. This review systematically summarizes and reviews analytical techniques such as targeted fishing technology， spectrum-effect relationship analysis， serum pharmacochemistry， network pharmacology， high-throughput screening， and cell membrane chromatography. It is found that these techniques exhibit unique advantages in areas including target-specific analysis， component-pharmacological effect correlation analysis， identification of the material basis in vitro and in vivo， prediction of multi-target mechanisms， efficient screening of active ingredients， and analysis of interactions between cell membrane receptors. These techniques compensate for the shortcomings of traditional research methods， enhance the systematicness and precision of research on pharmacodynamic substance based TCM compound prescriptions， and can provide theoretical support for the promotion and clinical application of TCM compound prescriptions.

METHODS Retrieved from PubMed， Embase， The Cochrane Library， CNKI database， Wanfang database and VIP database， the studies about the influential factors for the clinical efficacy of tigecycline in the treatment of adult patients with severe infections caused by MDR-GNB from the database construction to April 30， 2025. After screening literature， extracting data and evaluating the quality of literature， systematic review was performed by using RevMan 5.3 software. RESULTS A total of 14 studies involving 2 033 patients were included， of which 1 355 patients showed effective treatment outcomes. The meta-analysis results showed that Acute Physiology and Chronic Health Evaluation （APACHE）-Ⅱ ＞ 20 [OR＝4.50， 95%CI （2.28， 8.85）， P＜0.001]， malignant tumor [OR＝1.96， 95%CI （1.41， 2.72）， P＜0.001]， hemodialysis [OR＝2.09， 95%CI （1.40， 3.12）， P＜0.001]， septic shock [OR＝3.07， 95%CI （2.00， 4.72）， P＜0.001]， mechanical ventilation [OR＝2.31， 95%CI （1.57， 3.39）， P＜0.001]， coagulation dysfunction [OR＝ 3.03， 95%CI （2.09， 4.37）， P＜0.001]， glucocorticoids use＞3 days [OR＝2.26， 95%CI （1.14， 4.45）， P＝0.020]， and longer hospitalization time before using tigecycline [OR＝3.33， 95%CI （1.34， 8.30）， P＝0.010] were risk factors for the clinical efficacy of tigecycline in treatment of severe infections caused by MDR-GNB. Tigecycline initial double-dose regimen [OR＝0.23， 95%CI （0.13， 0.42）， P＜0.001]， combination therapy [OR＝0.15， 95%CI （0.05， 0.48）， P＝0.001]， and prolonged treatment course [OR＝0.91， 95%CI （0.88， 0.95）， P＜0.001] were protective factors. CONCLUSIONS There are many influential factors for the clinical efficacy of tigecycline in the treatment of severe infections caused by MDR-GNB， among which APACHE-Ⅱ score＞20， malignant tumor， hemodialysis， septic shock， mechanical ventilation， coagulation dysfunction， glucocorticoids＞3 d and longer hospitalization time before using tigecycline before tigecycline （No.20251606） use are risk factors； tigecycline double dose， combined medication and longer treatment course are protective factors.

Objective:To investigate the effect of dapagliflozin on non-dipper blood pressure in patients with diabetic kidney disease(DKD).Methods:A total of 104 patients with DKD treated in the Department of Nephrology of Henan Provincial Hospital of Tradi-tional Chinese Medicine from January 2023 to January 2024 were selected as the study subjects.The patients were divided into a dapa-gliflozin group and a control group by the random number table method,with 52 patients in each group.The control group was given conventional Western medicine treatment,and the dapagliflozin group was additionally given dapagliflozin(10 mg/dose,once a day)on the basis of the treatment in the control group.Both groups re-ceived continuous treatment for 12 weeks.The following indicators and the incidence of adverse reactions after treatment were com-pared between the two groups,including blood glucose indicators[fasting plasma glucose(FPG),2-hour postprandial blood glucose(2 h PBG),and glycated hemoglobin(HbA1c)],renal function markers[serum cystatin C(CysC),blood urea nitrogen(BUN),se-rum creatinine(Scr),estimated glomerular filtration rate(eGFR),and urinary albumin/creatinine ratio(UACR)],24-h ambulatory blood pressure,proportion of non-dipper blood pressure and reversal rate of dipper blood pressure,blood electrolytes[potassium(K),sodium,chlorine,calcium,magnesium,and phosphorus],serum uric acid(SUA),and urine electrolytes[urine potassium,urine sodium(UNa),urine chlorine,urine calcium,urine magnesium(UMg),and urine phosphorus].Results:The FPG,2 h PBG,HbA1c,CysC,BUN,Scr,UACR,mean 24 h systolic blood pressure(24 h SBP),mean daytime systolic blood pressure,and mean nighttime diastolic blood pressure were decreased and the eGFR was elevated in both groups after treatment.The mean nighttime systolic blood pressure(nSBP),K,and SUA were decreased and the UNa and UMg were increased in the dapagliflozin group after treatment(P<0.05).Com-pared with the control group,the dapagliflozin group experienced decreases in CysC,BUN,Scr,UACR,24 h SBP,nSBP,K,and SUA and increases in eGFR,UNa,and UMg after treatment(P<0.05).The proportion of non-dipper blood pressure after treatment in the dapagliflozin group was lower than that in the control group and before treatment,and the reversal rate of dipper blood pressure was higher than that in the control group(P<0.05).During treatment,the incidence rates of adverse reactions was 3.85%in the dapa-gliflozin group and 5.77%in the control group(P=1.000).Conclusion:Dapagliflozin improves the renal function,decreases the noctur-nal blood pressure,and increases the reversal rate of dipper blood pressure in patients with DKD.Dapagliflozin promotes UNa excre-tion and decreases the SUA level,which may be the potential mechanism of reversing non-dipper blood pressure.

Objective To investigate the molecular mechanism by which salidroside inhibits the proliferation of gastric cancer(GC)cells through upregulation of miR-1343-3p.Methods RNA databases were used to screen for mRNAs associated with tumor proliferation and with miR-1343-3p,and exhibiting significant changes in their expression levels after salidroside treatment of human GC cells.Gene matching and immunoprecipitation of RNA-binding proteins were conducted to analyze the association between miR-1343-3p and SOX18.Immunocytochemistry was performed to determine the localization of SOX18 protein.The effect of salidroside on the proliferation of human GC cells(MGC-803 and AGS)was determined by CCK-8 assay.Human GC cells were divided into a blank control group and low-and high-dose salidroside groups.The expression of miR-1343-3p and SOX18 mRNA was measured by real-time quantitative fluorescence PCR(qPCR).The protein expression of SOX18 was measured by Western blot.GC cells were co-transfected with miR-1343-3p mimic and miR-1343-3p inhibitor,respectively,via LipofectamineTM 2000 liposomes.The expression of miR-1343-3p and SOX18 mRNA was measured by qPCR,and the protein expression of SOX18 was measured by Western blot.Results Through bioinformatic analysis,SOX18 was identified as a downstream target of miR-1343-3p.Gene alignment confirmed the presence of specific binding sites between the two genes,and immunoprecipitation of RNA-binding proteins validated the targeting relationship between them(P<0.05).Immunocytochemistry demonstrated the nuclear localization of SOX18 protein.CCK-8 assay findings demonstrated that salidroside significantly inhibited the proliferation of GC cells in a time-and dose-dependent manner.Compared with the blank control group,salidroside-treated GC cells showed decreased expression of both SOX18 mRNA and protein(P<0.05)and an increased miR-1343-3p expression(P<0.05).Compared with the control group,GC cells in the miR-1343-3p mimic group exhibited increased expression of miR-1343-3p and decreased expression of SOX18 mRNA and protein.In contrast,GC cells in the miR-1343-3p inhibitor group showed decreased expression of miR-1343-3p and increased expression of SOX18 mRNA and protein(all P<0.05).Conclusion Salidroside may inhibit the proliferation of GC cells by regulating the miR-1343-3p/SOX18 signaling axis and these regulators may present new potential therapeutic targets or biomarkers for gastric cancer.

BACKGROUND:Our previous studies found that the polypeptide of Cornus cervi Colla can promote bone growth,which has a good application prospect in the treatment of bone diseases.However,how Cornus cervi Colla works in the body and the principle are not clear. OBJECTIVE:To study the in vivo distribution and tracing of Cornus cervi Colla using fluorescence labeling and tracer technique. METHODS:Cornus cervi Colla was fluorescently labeled using fluorescein isothiocyanate,and the labeling results were detected by fluorescence imaging and UV spectral scanning.Successfully labeled Cornus cervi Colla was injected into mice by gavage,and the absorption of Cornus cervi Colla into blood was detected by laser confocal microscopy,and the distribution of Cornus cervi Colla in mice was detected by small animal in vivo imager.The distribution of Cornus cervi Colla in the mice was detected by laser confocal microscopy.Samples were taken from serum and bone at the time of the strongest fluorescence,and gel electrophoresis was carried out on serum and bone tissue protein solutions,and the components of Cornus cervi Colla absorbed into target organs were determined by secondary mass spectrometry. RESULTS AND CONCLUSION:The fluorescent markers were successfully separated by dextran gel chromatography,and the fluorescence imaging and ultraviolet spectrum scanning proved that the labeling was successful,and the fluorescence substitution degree of FITC-labeled Cornus cervi Colla was 0.953%.The fluorescence intensity of the components of Cornus cervi Colla in the blood showed that Cornus cervi Colla was most distributed in serum after oral administration for 2 hours.The fluorescence images of mice at different times were the same as those of bilateral femur and tibia,indicating that Cornus cervi Colla could play a role by entering the bone.Compared with UniProt database,secondary mass spectrometry showed that the peptide was a characteristic fragment of decorin.It is proved that decorin in Cornus cervi Colla can enter the bone to play a therapeutic role.

BACKGROUND:Osteonecrosis of the femoral head is a common and disabling disease,which is mainly characterized by microcirculation disorders and bone cell metabolism disorders.Luzhongjiangu decoction was developed by Shandong Academy of Chinese Medicine and used in the form of soup in the clinic,which has good efficacy in the treatment of osteonecrosis of the femoral head.However,its mechanism of action has not been clarified. OBJECTIVE:To study the effect mechanism of Luzhongjiangu decoction on intestinal flora in rats with osteonecrosis of the femoral head based on 16S rDNA sequencing technique. METHODS:The model of osteonecrosis of the femoral head was established in Wistar rats by intragastric administration of retinoic acid.The therapeutic effect of Luzhongjiangu decoction was evaluated by serum hormone,bone histopathology and serum hormone levels.16s rDNA sequencing technique was used to detect the intestinal flora of rats in the blank control group,model group and middle-dose Luzhongjiangu decoction group.The corresponding library was constructed and OTU clustering and microbial community diversity and abundance analysis were carried out to determine the composition of intestinal flora and the changes of species and diversity among groups. RESULTS AND CONCLUSION:Luzhongjiangu decoction could significantly increase the expression of osteocalcin,osteopontin and other osteogenic related factors,alleviate the destruction of bone trabeculae,increase bone mineral density,and had a significant therapeutic effect on osteonecrosis of the femoral head,of which the middle dose group showed the most significant effect.The results of intestinal flora sequencing showed that Luzhongjiangu decoction improved the flora disorder of rats with osteonecrosis of the femoral head to some extent,and screened out different colonies such as Bacillus,Desulfurizans,Desulfurization,Isobacteria,Bifidobacterium and so on;it could up-regulate the abundance of beneficial bacteria such as Bifidobacterium,down-regulate the abundance of harmful bacteria such as Desulfovibrio,and improve the structure of intestinal flora.Functional prediction analysis indicated that Luzhongjiangu decoction could mainly affect amino acid metabolism and energy metabolism.Correlation analysis showed that the differential bacteria of Bifidobacterium and Intestinimonas in the middle dose group of Luzhongjiangu decoction were positively correlated with vitamin D3,estradiol and calcitonin,and negatively correlated with prostaglandin E2.In the model group,Escherichia-Shigella,Desulfovibrio,Globicatella and Streptococcus were positively correlated with prostaglandin E2 and negatively correlated with vitamin D3,estradiol and calcitonin.To conclude,Luzhongjiangu decoction may play a role in the treatment of osteonecrosis of the femoral head by regulating the structure of intestinal flora,up-regulating the abundance of beneficial bacteria and affecting the secretion of vitamin D3,estradiol,calcitonin and prostaglandin E2.
