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.

OBJECTIVE To systematically evaluate the influential factors for the clinical efficacy of tigecycline in the treatment of severe infections caused by multidrug-resistant Gram-negative bacteria （MDR-GNB）. 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.

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 and analyze the thyroid examination results and influencing factors of interventional radiation workers in Tianjin.Methods:In February 2023, A convenient sampling method was used to select the staff engaged in interventional radiation work in an occupational health inspection institution in Tianjin from 2020 to 2022 as the study object. After excluding the incomplete data, 1080 people were included, and 363 medical staff with non-radiological work during the same period were included as the control group. To analyze the individual doses and occupational health examination data of interventional radiation workers, and to analyze the possible influencing factors of thyroid abnormalities.Results:The cumulative dose M ( Q1, Q3) of interventional radiation workers was 1.039 (0.528, 1.905) mSv. The levels of FT 3 and FT 4 in the intervention group were higher than those in the control group, while TSH levels were lower than those in the control group ( Z=4.84、6.03、-5.82, P<0.05). The levels of FT 3 and FT 4 in female interventional radiation workers were lower than those in males, while the levels of TSH were higher than those in males ( Z= -17.54、-6.65、3.61, P<0.05). There were statistically significant differences in FT 3 levels among different ages, differen tradiation exposure years, different initial age of exposure to radiation, and different cumulative doses ( H=47.22、11.33、16.70, Z=-2.48, P<0.05). There were statistically significant differences in thyroid ultrasound abnormalities among different genders, different ages, different initial age of exposure to radiation, and different cumulative doses ( χ2=28.02、61.12、17.87、11.30, P<0.05). The results of logistic regression analysis showed that the influencing factors of FT 3 distributed in the low-level group were female ( OR=10.53, 95% CI: 7.66-14.47, P<0.05), and age 40-49, ≥50 years old ( OR=2.40, 95% CI: 1.12-5.14 OR=3.79, 95% CI: 1.59-9.03, P<0.05). The influencing factors of thyroid ultrasound abnormalities were female ( OR=1.92, 95% CI: 1.48-2.50, P<0.05) and age ≥50 years old ( OR=3.93, 95% CI: 1.91-8.09, P<0.05) . Conclusion:Long term low dose ionizing radiation has a certain effect on FT 3, FT 4 and TSH levels of interventional radiation workers. Gender and increased age are possible influencing factors of the decreased FT 3 levels and thyroid ultrasound abnormalities.

Objective Utilizing patient journey mapping to decipher disease management behaviors,barriers,and needs in young and middle-aged liver transplant recipients,providing implications for self-management optimization and quality of life improvement.Methods Using purposive sampling,12 young and middle-aged liver transplant patients who attended outpatient clinics or were hospitalized in liver transplant center of a tertiary hospital in Qingdao were selected for semi-structured interviews from September to November 2024.Thematic extraction and analysis were performed using Colaizzi's 7-step analysis,ultimately resulting in the development of a patient journey map.Results The journey stages were divided into transplantation decision-making period,transplantation waiting period,perioperative period,and post-discharge management period,and the journey key elements were designed as behaviors,barriers,and needs.A total of 25 themes were extracted,including behaviors(such as referrals to higher-level hospitals,verification of treatment options),barriers(such as lack of decision-making autonomy,health information-seeking barriers),and needs(such as shared decision-making,financial assistance).Ultimately,resulting in a map of the disease management journey for young and middle-aged liver transplant recipients.Conclusion The behaviors,barriers,and needs in disease management among young and middle-aged liver transplant recipients demonstrate distinct phase-specific patterns.Healthcare providers should deliver precise and dynamic interventions tailored to each clinical phase,aiming to foster optimal self-management behaviors,address phase-specific banriers,and meet evolving patient needs throughout the transplant continuum.

Objective To establish orthotopic and ectopic pancreatic cancer models in C57BL/6N mice with normal immune function using in vivo imaging technology for visual characterization.Methods Orthotopic and ectopic pancreatic cancer models were established in Kunming mice by injecting a small volume of cell suspension containing firefly luciferase-expressing Panc02-luciferase pancreatic cancer cells into the head of the pancreas or the right axillary region.In vivo imaging technology was used to optimize the modeling method and timing in Kunming mice.Subsequently,the same method was applied to C57BL/6N mice using wild-type Panc02 pancreatic cancer cells to establish orthotopic and ectopic pancreatic cancer models with intact immune function.Key parameters,including body weight,inoculation positive rate,tumor growth time,tumor volume,and pathological characteristics across different organs,were compared be-tween the orthotopic and ectopic models in C57BL/6N mice to evaluate the applicability of these models.Results Both the small animal in vivo imaging experiments in Kunming mice and the tumor growth observation in C57BL/6N mice demonstrated that the construction periods for orthotopic and ectopic pancreatic cancer models were 20 days,with survival rates exceeding 90%.The inoculation positive rates in C57BL/6N mice were 92.3%for the orthotopic model and 78.6%for the ectopic model.On day 20 post-inoculation,the tumor volumes were(117.04±109.56)mm3 for the orthotopic model and(155.68±168.73)mm3 for the ectopic model,indicating high model success rates and consistent tumor growth.HE staining revealed pathological mitotic figures and poorly differentiated tumor tissues in both models of C57BL/6N mice,with no evidence of metastasis to other organs.Conclusions Orthotopic and ectopic pancreatic cancer models in immu-nocompetent mice were successfully developed in this study,mimicking early-stage pancreatic cancer characteristics.These models pro-vide a reliable platform for screening early diagnostic biomarkers and evaluating therapeutic interventions for pancreatic cancer.

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.

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.

Objective To investigate the status of oral frailty(OF)in patients who underwent chemotherapy for lung cancer,identify key factors influencing OF,and develop a risk prediction model.Methods Using convenience sampling,431 lung cancer inpatient were recruited from three Tier-IIIA hospitals in Jiangsu Province between September and November 2024 as the training cohort.The patients were divided into OF and non-OF groups.Relevant data were compared between the two groups.Multifactorial logistic regression analysis was performed to determine factors that associated with OF,and a risk prediction model was created accordingly.Receiver operating characteristic(ROC)curve analysis was used to predict model performance.In December 2024,additional 185 patients from one other Tier-IIIA hospitals were recruited to validate the developed model.Results The prevalence of OF among lung-cancer patients undergoing chemotherapy was 58.93%.Following listed items were identified as the risk factors of OF(all P<0.05):older in age(OR=3.420),poor education(OR=0.030),brain metastasis(OR=7.880),high nutritional risk screening 2002 score(OR=1.550),elevated C-reactive protein(OR=1.100),and elevated lactate dehydrogenase(OR=1.010).ROC area under the curve(AUC)of the model was 0.860(95%CI:0.830-0.900)in modelling cohort and 0.840(95%CI:0.780-0.900)in validation cohort.Hosmer-Lemeshow goodness-of-fit test yielded χ 2=4.870,P=0.770 for the training set and χ 2=2.770,P=0.950 for the validation set.Conclusion The risk prediction model for OF developed in this study demonstrates a good predictive performance and can facilitate early identification of high-risk patients,thereby providing a scientific basis for clinical interventions.

Objective:To investigate the clinical efficacy and safety of ultrasound-guided thyroid injection of dexamethasone in the treatment of subacute thyroiditis (SAT).Methods:This is a randomized controlled study involving 32 patients with SAT who received treatment at Endocrinology Clinic of Heilongjiang Provincial Hospital between June 2022 and March 2023. The patients were randomly divided into an observation group and a control group ( n = 16 per group) using a random number table method. The observation group received ultrasound-guided injection of dexamethasone (5 mg per injection, once a week) into the thyroid lesion, while the control group was treated with oral prednisone acetate tablets (5 mg per dose, three times a day). Both groups were treated for 4 weeks. The clinical efficacy, time taken for body temperature to return to normal, time for pain resolution, time for goiter regression, time for thyroid function to normalize, as well as recurrence rates and adverse reactions, were compared between the two groups. Results:The response rate in the observation group was 100% (16/16), which was significantly higher than that in the control group [75% (12/16), χ2 = 4.57, P = 0.033]. The time taken for body temperature to return to normal, the time for goiter regression, and the time for goiter regression in the observation group were (3.5 ± 3.6) days, (7.4 ± 2.5) days, and (11.6 ± 7.4) days, respectively, which were significantly shorter than those in the control group [(6.1 ± 3.2) days, (9.9 ± 3.5) days, (16.9 ± 6.8) days, t = -2.16, -2.33, -2.11, all P < 0.05]. After 4 weeks of treatment, the observation group showed significantly lower body mass index, fasting blood glucose, and serum triglyceride levels compared to the control group ( t = -2.07, -2.46, -2.13, all P < 0.05). The recurrence rate in the observation group was 0%, which was significantly lower than that in the control group [25% (4/16), χ2 = 4.57, P = 0.033]. Conclusions:The efficacy and safety of ultrasound-guided local thyroid injection of dexamethasone for the treatment of SAT are superior to those of the oral treatment regimen.
