Objective To investigate the cardiac structural and functional characteristics in the patients with heart failure with preserved ejection fraction (HFpEF) and type 2 diabetes mellitus (T2DM),and predict the factors influencing the characteristics. Methods A total of 783 HFpEF patients diagnosed in the Department of Geriatric Cardiology,the First Hospital of Lanzhou University from April 2009 to December 2020 were enrolled in this study.Echocardiography and tissue Doppler technique were employed to evaluate cardiac structure and function.According to the occurrence of T2DM,the patients were assigned into a HFpEF+T2DM group (n=332) and a HFpEF group (n=451).Propensity score matching (PSM)(in a 1∶1 ratio) was adopted to minimize confounding effect.According to urinary albumin excretion rate (UAER),the HFpEF+T2DM group was further divided into three subgroups with UAER<20 μg/min,of 20-200 μg/min,and>200 μg/min,respectively.The comorbidities,symptoms and signs,and cardiac structure and function were compared among the groups to clarify the features of diabetes related HFpEF.Multivariate linear regression was conducted to probe the relationship of systolic blood pressure,blood glucose,glycosylated hemoglobin,and UARE with cardiac structural and functional impairment. Results The HFpEF+T2DM group had higher prevalence of hypertension (P=0.001) and coronary heart disease (P=0.036),younger age (P=0.020),and larger body mass index (P=0.005) than the HFpEF group,with the median diabetic course of 10 (3,17) years.After PSM,the prevalence of hypertension and coronary heart disease,body mass index,and age had no significant differences between the two groups(all P>0.05).In addition,the HFpEF+T2DM group had higher interventricular septal thickness (P=0.015),left ventricular posterior wall thickness (P=0.040),and left ventricular mass (P=0.012) and lower early diastole velocity of mitral annular septum (P=0.030) and lateral wall (P=0.011) than the HFpEF group.Compared with the HFpEF group,the HFpEF+T2DM group showed increased ratio of early diastolic mitral filling velocity to early diastolic mitral annular velocity (E/e') (P=0.036).Glycosylated hemoglobin was correlated with left ventricular mass (P=0.011),and the natural logarithm of UAER with interventricular septal thickness (P=0.004),left ventricular posterior wall thickness (P=0.006),left ventricular mass (P<0.001),and E/e' ratio (P=0.049). Conclusion The patients with both T2DM and HFpEF have thicker left ventricular wall,larger left ventricular mass,more advanced left ventricular remodeling,severer impaired left ventricular diastolic function,and higher left ventricular filling pressure than the HFpEF patients without T2DM.Elevated blood glucose and diabetic microvascular diseases might play a role in the development of the detrimental structural and functional changes of the heart.

The UPLC-MS/MS was established for the determination of acetyl-11-keto-beta-boswellic acid(AKBA) and β-boswellic acid(β-BA), the main active components of Olibanum and Myrrha extracts in Xihuang Formula, in rat plasma and urine. The effects of compatibility on the pharmacokinetic behaviors of AKBA and β-BA in rats were investigated, and the differences in pharmacokinetic behaviors between healthy rats and rats with precancerous lesions of breast cancer were compared. The results showed that compared with RM-NH and RM-SH groups, the AUC_(0-t) and AUC_(0-∞) of β-BA increased(P<0.05 or P<0.01), T_(max) decreased(P<0.05 or P<0.01), and C_(max) increased(P<0.01) after compatibility. The trends of AKBA and β-BA were the same. Compared with RM-SH group, the T_(max) decreased(P<0.05), C_(max) increased(P<0.01), and the absorption rate increased in the normal group of Xihuang Formula. The results of urinary excretion showed that there was a decreasing trend in the urinary excretion rate and total urinary excretion of β-BA and AKBA after compatibility, but there was no statistical difference. Compared with normal group of Xihuang Formula, the AUC_(0-t) and AUC_(0-∞) of β-BA increased(P<0.05), T_(max) increased(P<0.05), and the clearance rate decreased in the breast precancerous lesion group. AUC_(0-t) and AUC_(0-∞) of AKBA showed an increasing trend, the in vivo retention time was prolonged, and the clearance rate was reduced, but there was no significant difference compared with the normal group. The cumulative urinary excretion and urinary excretion rate of β-BA and AKBA decreased under pathological conditions, indicating that pathological conditions could affect the in vivo process of β-BA and AKBA, and reduce their excretion in the form of prototype drugs, showing different pharmacokine-tic characteristics from normal physiological conditions. In this study, UPLC-MS/MS analysis method was established, which was sui-table for in vivo pharmacokinetic analysis of β-BA and AKBA. This study laid a foundation for the development of new dosage forms of Xihuang Formula.

摘要
Renal tubular secretion mediated by organic anion transporters(OATs)and the multidrug resistance-associated protein 4(MRP4)is an important means of drug and toxin excretion.Unfortunately,there are no biomarkers to evaluate their function.The aim of this study was to identify and characterize an endogenous biomarker of the renal tubular OATs-MRP4 channel.Twenty-six uremic toxins were selected as candidate compounds,of which kynurenic acid was identified as a potential biomarker by assessing the protein-binding ratio and the uptake in OAT1-,OAT3-,and MRP4-overexpressing cell lines.OAT1/3 and MRP4 mediated the transcellular vectorial transport of kynurenic acid in vitro.Serum kynurenic acid concentration was dramatically increased in rats treated with a rat OAT1/3(rOAT1/3)inhibitor and in rOAT1/3 double knockout(rOAT1/3-/-)rats,and the renal concentrations were markedly elevated by the rat MRP4(rMRP4)inhibitor.Kynurenic acid was not filtered at the glomerulus(99％of albumin binding),and was specifically secreted in renal tubules through the OAT1/3-MRP4 channel with an appropriate affinity(Km)(496.7 μM and 382.2 μM for OAT1 and OAT3,respectively)and renal clearance half-life(ti/2)in vivo(3.7±0.7 h).There is a strong correlation in area under the plasma drug concentration-time curve(AUC0-t)between cefmetazole and kynurenic acid,but not with creatinine,after inhibition of rOATs.In addition,the phase of increased kynurenic acid level is earlier than that of creatinine in acute kidney injury process.These results suggest that albumin-bound kynurenic acid is an appropriate endogenous biomarker for adjusting the dosage of drugs secreted by this channel or predicting kidney injury.

Objective To investigate the association of uric acid excretion(UUAE)with obesity and abdominal obesity in newly diagnosed patients with type 2 diabetes mellitus(T2DM).Methods A total of 1175 newly diagnosed T2DM patients hospitalized in the Department of Endocrinology and Metabolism of Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were enrolled in this study from January 2006 to December 2012.According to the quartile of UUAE,they were divided into Q1 group(UUAE＜2383 μmol/24 h,n=295),Q2 group(2383≤UUAE＜2953 μmol/24 h,n=292),Q3 group(2954≤UUAE＜3680 μmol/24 h,n=292)and Q4 group(UUAE＞3680 μmol/24 h,n=293).Clinical data and laboratory examination results were collected,and the prevalence of obesity and abdominal obesity was compared among the four groups.The associations of UUAE with obesity and abdominal obesity were analyzed.Results The prevalence of obesity was 47.9%,while the prevalence of abdominal obesity was 61.9%in the whole study population.After adjusting for age,the prevalence of abdominal obesity was higher in women than in men(P＜0.05).After adjusting for age and gender,the prevalence of obesity and MS was higher in Q4 group than in Q1,Q2,and Q3 groups(P＜0.05),and the prevalence of abdominal obesity was higher in Q4 group than in Q1 and Q2 groups(P＜0.05).Compared with Q1 group,the proportion of men,BMI,WC,DBP,FIns,2 hIns,HOMA-IR,TG,ALT,γ-GT,SUA,UAlb in Q4 group increased(P＜0.05),age,HbA1c,HDL-C decreased(P＜0.05).Logistic regression analysis showed that after adjusting for confounding factors,UUAE was a factor affecting obesity and abdominal obesity.Conclusion UUAE increases the risk of obesity,abdominal obesity and MS in newly diagnosed T2DM patients.UUAE may be used as a simple indicator to assess the risk of metabolic disorders such as obesity and MS in T2DM patients.
摘要
Biliary atresia is a rare infant disease that predisposes patients to liver transplantation and death if not treated in time. However, early diagnosis is challenging because the clinical manifestations and laboratory tests of biliary atresia overlap with other cholestatic diseases. Therefore, it is very important to develop a simple, safe and reliable method for the early diagnosis of biliary atresia. Herein, a novel NIR-II fluorescence probe, HZL2, with high quantum yield, excellent biocompatibility, low cytotoxicity and rapid excretion through the liver and gallbladder was developed based on the oil/water partition coefficient and permeability. A simple fecal sample after injection of HZL2 can be used to efficiently identify the success of the mouse model of biliary atresia for the first time, allowing for an early diagnosis of the disease. This study not only developed a simple and safe method for the early diagnosis of biliary atresia with great potential in clinical translation but also provides a research tool for the development of pathogenesis and therapeutic medicines for biliary atresia.
摘要
This study investigated the differences in excretion kinetics of three alkaloids and their four metabolites from Simiao Pills in normal and type 2 diabetic rats. The diabetes model was established in rats by injection of streptozotocin, and the alkaloids in urine, feces, and bile of normal and diabetic rats were detected by LC-MS/MS to explore the effect of diabetes on alkaloid excretion of Simiao Pills. The results showed that 72 h after intragastric administration of the extract of Simiao Pills, feces were the main excretion route of alkaloids from Simiao Pills. The total excretion rates of magnoflorine and berberine in normal rats were 4.87% and 56.54%, which decreased to 2.35% and 35.53% in diabetic rats, which had statistical significance(P<0.05). The total excretion rates of phellodendrine, magnoflorine, and berberine in the urine of diabetic rats decreased significantly, which were 53.57%, 60.84%, and 52.78% of those in normal rats, respectively. After 12 h of intragastric administration, the excretion rate of berberine in the bile of diabetic rats increased significantly, which was 253.33% of that of normal rats. In the condition of diabetes, the excretion rate of berberine metabolite, thalifendine significantly decreased in urine and feces, but significantly increased in bile. The total excretion rates of jateorrhizine and palmatine in the urine increased significantly, and t_(1/2) and K_e changed significantly. The results showed that diabetes affected the in vivo process of alkaloids from Simiao Pills, reducing their excretion in the form of prototype drug, affecting the biotransformation of berberine, and ultimately increasing the exposure of alkaloids in vivo, which would be conducive to the hypoglycemic effect of alkaloids. This study provides references for the clinical application and drug development of Simiao Pills in diabetes.

The treatment of patients with diabetes mellitus, which is characterized by defective insulin secretion and/or the inability of tissues to respond to insulin, has been studied for decades. Many studies have focused on the use of incretin-based hypoglycemic agents in treating type 2 diabetes mellitus (T2DM). These drugs are classified as GLP-1 receptor agonists, which mimic the function of GLP-1, and DPP-4 inhibitors, which avoid GLP-1 degradation. Many incretin-based hypoglycemic agents have been approved and are widely used, and their physiological disposition and structural characteristics are crucial in the discovery of more effective drugs and provide guidance for clinical treatment of T2DM. Here, we summarize the functional mechanisms and other information of the drugs that are currently approved or under research for T2DM treatment. In addition, their physiological disposition, including metabolism, excretion, and potential drug-drug interactions, is thoroughly reviewed. We also discuss similarities and differences in metabolism and excretion between GLP-1 receptor agonists and DPP-4 inhibitors. This review may facilitate clinical decision making based on patients' physical conditions and the avoidance of drug-drug interactions. Moreover, the identification and development of novel drugs with appropriate physiological dispositions might be inspired.
摘要
The use of antimicrobials as growth promoters and disease prevention is being constantly reduced in several animal production systems, including in the swine industry. Therefore, this study aimed to evaluate the effectiveness of using acidifiers to control Salmonella Typhimurium in 65-day-old pigs by detecting the pathogen in organs at euthanasia. For this, 24 piglets were divided into two experimental groups consisting of 12 piglets each. An untreated control group (G1) and a treatment group (G2) received a liquid organic acidifier in the drinking water for 10 days (D-5 to D5). Five days after the start of treatment (D0), all piglets were challenged with 106 CFU of Salmonella Typhimurium and assessed for 12 days (D12). Every three days (D3, D6, D9, and D12), three animals from each experimental group were euthanized and then submitted for necropsy. Samples from the intestines (ileum, cecum, mesenteric lymph nodes, and ileocolic lymph nodes), liver, spleen, and lungs were collected to isolate Salmonella. The results show that, numerically, Salmonellaisolation in the organs of G2 was lower than in G1 and that the number of positive cecum samples in G1 (66.7%; 8/12) was statistically different from the number of positive models in G2 (16.7%; 2/12), with a reduction of 28.6% of the total cecum positive samples in the treated group compared to the control. Therefore, it was observed that the liquid organic acidifier product could reduce the colonization of organs by Salmonella Typhimurium.(AU)
O uso de antimicrobianos como promotores de crescimento e prevenção de doenças vem sendo constantemente reduzido em diversos sistemas de produção animal, inclusive na suinocultura. Portanto, o objetivo do presente estudo foi avaliar a eficácia do uso de acidificantes no controle de Salmonella Typhimurium em suínos de 65 dias de idade, detectando o patógeno em órgãos após a eutanásia. Para isso, 24 leitões foram divididos em dois grupos experimentais constituídos por 12 leitões cada. Um grupo controle não tratado (G1) e um grupo de tratamento (G2) que recebeu um acidificante orgânico líquido na água de beber por 10 dias (D-5 a D5). Cinco dias após o início do tratamento (D0), todos os animais foram inoculados oralmente com 106 UFC de Salmonella Typhimurium e avaliados por 12 dias (D12). A cada três dias (D3, D6, D9 e D12), três leitões de cada grupo experimental foram eutanasiados e posteriormente submetidos à necropsia. Amostras de intestino (íleo, ceco, linfonodos mesentéricos e linfonodos ileocólicos), fígado, baço e pulmões foram coletadas para o isolamento de Salmonella. Os resultados mostram que, numericamente, o isolamento de Salmonella nos órgãos do G2 foi inferior ao G1, e que o número de amostras positivas de ceco no G1 (66,7%; 8/12) foi estatisticamente diferente do número de amostras positivas no G2 (16,7%; 2/12), com redução de 28,6% do total de amostras positivas de ceco no grupo tratado em relação ao controle. Portanto, observou-se que o ácido orgânico líquido foi capaz de reduzir a colonização de órgãos por Salmonella Typhimurium.(AU)

Abstract In the present study, the application of ultra-high performance liquid chromatography-tandem mass spectrometry allowed us to study of known-as well as hitherto unknown-trimetazidine (TMZ) metabolites in human urine and to propose their renal excretion profiles. Urine samples from a healthy volunteer were analyzed at baseline and at 0-4 h, 4-8 h, 8-12 h, and 12-24 h after a single dose of TMZ. A dilute-and-shoot procedure was used as sample treatment before separation. Full-scan spectra of possible metabolites were acquired. Additionally, product ion scan spectra of precursor ions of interest were also acquired at two collision energies. Intact TMZ was a major excretion product, with a maximum concentration at 4-8 h after administration. Moreover, five minor metabolites were observed, namely trimetazidine-N-oxide (M1), N-formyl trimetazidine (M2), desmethyl-trimetazidine O-sulfate (M3), desmethyl-trimetazidine O-glucuronide (M4), and desmethyl-trimetazidine-N-oxide-O-glucuronide (M5). Metabolite M5 has not previously been reported. Excretion curves were constructed based on the chromatographic peak areas of specific mass transitions (precursor ion > product ion) related to each of the detected metabolites

Introducción. La creciente resistencia bacteriana a los antibióticos representa una amenaza mundial de salud pública. Las excreciones y secreciones larvarias derivadas de moscas necrófagas de la familia Calliphoridae podrían configurar una fuente promisoria para contrarrestar sus efectos. Objetivo. Comparar la actividad antimicrobiana de las excreciones y secreciones larvarias nativas, y de las mayores y menores de 10 kDa de Calliphora vicina y Sarconesiopsis magellanica (Diptera: Calliphoridae). Materiales y métodos. El bioensayo se hizo a partir de la técnica de turbidimetría y en el caso de las excreciones y secreciones menores de 10 kDa se determinó la concentración inhibitoria mínima (CIM). Resultados. Las excreciones y secreciones nativas y las menores de 10 kDa de C. vicina y S. magellanica, evidenciaron una potente actividad antibacteriana contra tres cepas de Staphylococcus aureus y cuatro bacterias Gram negativas, siendo las menores de 10 kDa más efectivas que las nativas en las dos especies de moscas evaluadas. Además, las menores de 10 kDa presentaron la misma efectividad, aunque en las pruebas de CIM se observó que las de S. magellanica fueron más potentes en todas las bacterias evaluadas, excepto contra la cepa de S. aureus ATCC 25923. Las mayores de 10 kDa no inhibieron el crecimiento bacteriano. Conclusión. Los resultados validaron, en general, que estas sustancias son fuente importante para el aislamiento y la caracterización de agentes antimicrobianos.
Introduction: The growing resistance to antibiotics worldwide represents a global threat to public health. The larval excretions and secretions derived from necrophagous flies from the Calliphoridae family could represent a promising source for counteracting their effects. Objective: To compare the antimicrobial activity of Calliphora vicina and Sarconesiopsis magellanica (Diptera: Calliphoridae) native excretions and secretions and those weighing more than 10 kDa and less. Materials and methods: We used the turbidimetry technique for the bioassay; we determined the minimum inhibitory concentration (MIC) for excretions and secretions weighing less than 10 kDa. Results: Calliphora vicina and S. magellanica native excretions and secretions and those weighing less than 10 kDa exhibited potent antibacterial activity against three Staphylococcus aureus strains and four Gram-negative bacteria; those weighing less than 10 kDa were more effective than the native ones in the two species of flies evaluated here. Furthermore, excretions and secretions weighing less than 10 kDa had the same effectiveness, except in the MIC trials where S. magellanica excretions and secretions weighing less than 10 kDa were more potent against all the bacteria evaluated, except for S. aureus ATCC 25923. Excretions and secretions weighing more than 10 kDa did not inhibit bacterial growth. Conclusions: These results potentially validate these substances as an important source for isolating and characterizing antimicrobial agents.

Hypertension is a common medical condition; its prevalence increases with age. It is one of the most important risk factors for cardiovascular disease, which is the leading cause of mortality. High salt intake is associated with high blood pressure. The incidence of hypertension is higher in salt-sensitive individuals. Evidence shows that reduced sodium intake lowers blood pressure and can prevent hypertension. Urinary sodium excretion was used as measure of sodium intake, which equals urinary excretion under normal circumstances. The relationship between salt intake and renal ability to excrete sodium has suggested being a major importance for the long-term blood pressure treatment especially in essential hypertension. In the present study there was increased 24 hour sodium excretion in essential hypertensives indicating a high intake of sodium, which may be the cause for hypertension. Patients with high sodium excretion, who are salt sensitive hypertensives will respond to diuretics, when compared to others. The long term reduction in salt intake may significantly reduce the prevalence of hypertension and thereby decrease the associated morbidity and mortality.

Introducción: Las infecciones de transmisión sexual constituyen un relevante problema de salud a nivel mundial; particularmente afectan la salud sexual de las mujeres ocasionando dolencias y efectos muy negativos, como la infertilidad, los embarazos ectópicos y el cáncer cervicouterino. Objetivo: Describir las características epidemiológicas de las infecciones de transmisión sexual relevantes en mujeres de Santiago de Cuba. Métodos: Se realizó un estudio descriptivo y retrospectivo en la provincia de Santiago de Cuba de la población femenina que presentó infecciones de transmisión sexual durante el período 2007-2017, detallando cada afección según año, municipio, edad, entre otras variables de interés. Asimismo, se analizaron la frecuencia, las tasas de incidencia, las tendencias y las variaciones temporales. Resultados: Las entidades clínicas predominantes fueron el síndrome de dolor pélvico y la secreción vaginal, en tanto, las menos frecuentes resultaron ser el herpes genital y la blenorragia. En el análisis por cada tipo de infección se observó una mayor afectación en féminas de edades jóvenes. Conclusiones: Las infecciones de transmisión sexual constituyen un serio problema de salud en mujeres de la provincia de Santiago de Cuba, que deviene causa importante de embarazos ectópicos y esterilidad. Sin embargo, se debe mejorar la vigilancia epidemiológica de estas enfermedades, pues existe un marcado subregistro de algunas y, por ende, una inadecuada atención, sobre todo en el sexo femenino.
Introduction: Sexually transmitted infections constitute an outstanding health problem worldwide; they particularly affect the sexual health of women causing ailments and very negative effects as infertility, ectopic pregnancies and cervical uterine cancer. Objective: To describe the epidemiologic characteristics of the outstanding sexually transmitted infections in women from Santiago de Cuba. Methods: A descriptive and retrospective study was carried out in the province of Santiago de Cuba in the female population that presented sexually transmitted infections during 2007-2017, with details of each affection according to year, municipality, age, among other variables of interest. Also, frequency, rates of incidence, tendencies and temporary variations were analyzed. Results: The predominant clinical entities were the pelvic pain syndrome and vaginal secretion, as long as, the less frequent were genital herpes and blennorrhagia.

Objective:To evaluate 90Y activity concentration in renal excretions during the first 48 hours after being treated with 90Y resin microspheres seleceive internal radiation therapy(SIRI) and to provide advice on the management of patient excreta after surgery. Methods:After surgery, urine excreted from 3 patients during 0-24 h and 24-48 h was collected respectively, and the 90Y activity concentration in urine was tested and analyzed. Results:90Y radioctivity in the urine excreted from 3 patients after surgery was (1 266±258)kBq/GBq during 0-24 h and (140±106) kBq/GBq during 24-48 h, respectively, and 90Y activity concentration were (640±113) kBq/L during 0-24 h and (53±12) kBq/L during 24-48 h. Conclusions:90Y radioactivity in patient′s urine excreted at 1 d was about 10 times higher than that at 2 d. After surgery, patients can accelerate the reduction of free 90Y activity by increasing excretion. Urine excreted by the patients during hospitalization should be handled in accordance with the requirements of the national standard HJ 1188-2021 Radiation protection and safety requirements for nuclear medicine.
摘要
d-α-Tocopheryl polyethylene glycol 1000 succinate (TPGS, also known as vitamin E-TPGS) is a biodegradable amphiphilic polymer prepared by esterification of vitamin E with polyethylene glycol (PEG) 1000. It is approved by the US Food and Drug Administration (FDA) and has found wide application in nanocarrier drug delivery systems (NDDS). Fully characterizing the in vivo fate and pharmacokinetic behavior of TPGS is important to promote the further development of TPGS-based NDDS. However, to date, a bioassay for the simultaneous quantitation of TPGS and its metabolite, PEG1000, has not been reported. In the present study, we developed such an innovative bioassay and used it to investigate the pharmacokinetics, tissue distribution and excretion of TPGS and PEG1000 in rat after oral and intravenous dosing. In addition, we evaluated the interaction of TPGS with cytochromes P450 (CYP450s) in human liver microsomes. The results show that TPGS is poorly absorbed after oral administration with very low bioavailability and that, after intravenous administration, TPGS and PEG1000 are mainly distributed to the spleen, liver, lung and kidney before both being slowly eliminated in urine and feces as PEG1000. In vitro studies show the inhibition of human CYP450 enzymes by TPGS is limited to a weak inhibition of CYP3A4. Overall, our results provide a clear picture of the in vivo fate of TPGS which will be useful in evaluating the safety of TPGS-based NDDS in clinical use and in promoting their further development.

Objective:Using 24-hour urinary sodium excretion (24h-UNa) as the surrogate measure of sodium intake, to evaluate the joint association of 24h-UNa and serum 25-hydroxy vitamin D (25-OHD) levels with the risk of albuminuria in patients with type 2 diabetes mellitus (T2DM).Methods:This retrospective study included 670 hospitalized T2DM cases in the Department of Endocrinology and Metabolic Diseases, the First Affiliated Hospital of Zhengzhou University from January 2018 to October 2021. Patients were divided into the albuminuria-positive group or negative-group according to the level of 24-hour urinary albumin excretion (24h-UAE); They were also divided into the high-sodium group or low-sodium group according to the level of 24h-UNa; Patients were divided into the low-VD group or high-VD group according to the level of 25-OHD. Combining 24h-UNa and 25-OHD, the patients were further divided into four groups: high-VD low-sodium group ( n=85), high-VD high-sodium group ( n=122), low-VD low-sodium group ( n=248), and low-VD high-sodium group ( n=215). The effect of 24h-UNa and 25-OHD association on albuminuria was analyzed by binary regression. Results:There were significant differences in 24h-UAE level among the four groups ( P<0.01), the level of 24h-UAE in the low-VD high-sodium group was significantly higher than that in low-VD low-sodium group, high-VD low-sodium group, and high-VD high-sodium group [39.00(13.00, 319.00)mg/24 h vs 22.00(10.00, 99.00)mg/24 h, 22.00(9.00, 72.50)mg/24 h, 22.45(9.69, 72.75)mg/24 h; P=0.047, P=0.019, P=0.030]. Correlation analysis showed a positive correlation between 24h-UNa and 24h-UAE in the low-VD group ( P=0.017), but not in the high-VD group ( P=0.411). Binary regression analyses showed that both 24h-UNa ( P=0.017) and 25-OHD( P=0.023) were independent risk factors for positive albuminuria in patients with T2DM. The risk of positive albuminuria in the low-VD high-sodium group was 1.789 times higher than that in the high-VD low-sodium group ( P=0.037). Conclusion:24h-UAE in T2DM patients was affected by the combination of 24h-UNa and 25-OHD. A low level of 25-OHD increased the risk of albuminuria in high sodium intake T2DM patients.
摘要
AIM: To explore the effects of inflammatory conditions on the pharmacokinetics of methotrexate (MTX) and its related mechanisms. METHODS: The model of adjuvant induced arthritis (AIA) was established. The expression of organic anion transporter 3 (OAT3) in kidney was detected by immunohistochemistry, Western blotting and QPCR. The plasma concentration of MTX was detected by LC-MS/MS, and the pharmacokinetics of MTX after different administration time were compared by isolated rat kidney perfusion, kidney slices, in vitro cell uptake and transport experiments. RESULTS: The expression of OAT3 was significantly increased in the kidneys of AIA rats by immunohistochemistry, Western blotting and QPCR. At the same time, the concentration of MTX was detected by the optimized LC-MS/MS. The results showed that the uptake of MTX in the kidney slices of AIA rats was significantly increased, and Pro could reduce the excretion of MTX by inhibiting OAT3. Furthermore, it was demonstrated in vitro that inflammatory pathology can promote renal excretion of MTX by increasing the expression and functional activity of OAT3.CONCLUSION: Under inflammatory pathological conditions, it can increase the expression of OAT3 in the kidney, enhance its functional activity, accelerate the uptake of MTX by the kidney, and promote the excretion of MTX.
