[Method] The method of self-control was adopted. Five two-year-old male Kazak sheep about 40 kg which never had intake of the feeds containing gossypol were selected. The experiment was divided into five periods, namely the control period, a period with the supplement of 300 mg/d of hydrochlorothiazide, a period with the supplement of 200 mg/d of hydrochlorothiazide, a period with the supplement of 350 mg of GY-01 and a period with the supplement of 200 mg of GY-01. The sheep were fed with the concentrate and the cottonseed hulls in the control period, and corresponding diuretics were supplemented in the rest four periods. The water drinking amount, urination volume and the contents of the hormone and ion in the blood were determined in each period. [Result] After 350 mg GY-01 was supplemented, the water drinking amount of each sheep had an increase of 60.14% compared with that of the sheep in the control period and the urination volume was 2.67 times of that of the latter, and the differences were both significant （P0.01）. The antidiuretic hormone declined by 32.59% compared with that of the sheep in the control period, with the significant difference （P 0.05）. The adrenocorticotropic hormone content increased by 81.93% compared with that of the sheep in the control period and the difference was significant （P0.01）. An increase of 28.04% （P 0.05） and 39.39% （P 0.01） was found in the contents of serum potassium and phosphorus respectively compared with that of sheep in the control period. [Conclusion] The diet with supplement of GY-01 can increase the urination volume of livestock fed with the cottonseed hulls, and the most appropriate supplement amount is 200 mg GY-01.展开更多

Unlike modern acupuncture needles, the DZ is not inserted subcutaneously and is considered to be safe for common use, even at the bedside of terminally ill patients. In this case study, DZ application was selected and applied 14 times on a 92-year-old patient who had suffered severe oliguria along with administration of diuretics. Urine volume increased 12 out of 14 times following DZ treatment;however, the other two times it was ineffective. To investigate the reason and the differences in effective/ineffective DZ application, two internal conditions (effective vs ineffective) were compared by analyzing daily nursing reports (vital signs such as blood pressure, urine volume and body temperature) and weekly clinical data (including renal, liver and immune function, urea nitrogen, creatinine, ALT, AST, the ratio and number of leukocytes, erythrocytes). DZ application increased urine volume via a transient modification of the autonomic nervous system when internal homeostasis was maintained. Aging populations, who often have several diseases and medications, are rapidly increasing in developed countries. Therefore, the study and application of DZ may contribute to a reduction in medical costs, which have been rapidly and heavily expanding recently.展开更多

Methods： The changes of pre-and post-operative residual urine volume （RUV） in patient undergoing complete PANP （n = 15） and incomplete PANP （n = 17） were observed. Results： In fifteen cases with complete PANP, preoperative RUV was 4.09 ml, 14 days and 3 months after operation RUV were 8.00 ml and 7.02 ml （P 〉 0.05）. In seventeen cases with incomplete PANP, preoperative RUV was 3.90 ml, 14 days and 3 months after operation RUV were 36.55 ml and 22.64 ml （P 〈 0.001 ）. Conclusion： Complete and incomplete pelvic autonomic preservation may affect urination function in patients with resection of rectal carcinoma and RUV is an effective indicator if the pelvic autonomic nerves are preserved completely.展开更多

Walp. is an economically important seed legume that helps combat food and nutrition insecurity in the Sahel, particularly Niger. However, its yield remains low due to insect pest attacks. This study was conducted at a station and in seven villages in the Maradi and Tahoua regions. It aimed to test the effectiveness of neem seed biopesticides [Azadirachta indica A. Juss] and sanitized human urine for integrated insect pest management. The cowpea variety UAM09 1055-6 was used for the experiments. The experimental trial was a Fisher block design consisting of five treatments: neem oil, neem seed extract (NSE), hygienized human urine (HHU), chemical pesticide, and a control, replicated five times at the station and twice in farmers’ environments. The study shows that Megalurothrips sjostedti Trybom, Clavigralla tomentosicollis Stål and Maruca vitrata Fabricius are the main insect pests. Plots treated with synthetic pesticides were the least infested by C. tomentosicollis. They were followed by neem seed extract and HHU treatments, which recorded an infestation level of 2.44 and 20.5 times lower than controls at the station and in farming environments. The density of thrips was 1.06 to 32.6 times lower in treated plots compared to controls. The proportion of pods damaged by M. vitrata was 1.95, 2.55, and 2.77 times lower in plots treated with HHU, NSE, and synthetic pesticide, respectively, compared to controls. Grain yields were 1.80 and 2.62 times higher in UHH and NSE treatments compared to control plots, both at the station and in farmers’ environments. A yield increase of 44.58% and 61.92% was noted for these treatments at the station and in farmers’ environments, respectively. These results may promote the dissemination of NSE and HHU biopesticide technologies in rural areas as an alternative method for integrated pest management of cowpeas.展开更多

文摘[Objective] This study aimed to investigate the effects of three kinds of diuretics on the water drinking amount and urination volume of sheep fed with cottonseed hulls. [Method] The method of self-control was adopted. Five two-year-old male Kazak sheep about 40 kg which never had intake of the feeds containing gossypol were selected. The experiment was divided into five periods, namely the control period, a period with the supplement of 300 mg/d of hydrochlorothiazide, a period with the supplement of 200 mg/d of hydrochlorothiazide, a period with the supplement of 350 mg of GY-01 and a period with the supplement of 200 mg of GY-01. The sheep were fed with the concentrate and the cottonseed hulls in the control period, and corresponding diuretics were supplemented in the rest four periods. The water drinking amount, urination volume and the contents of the hormone and ion in the blood were determined in each period. [Result] After 350 mg GY-01 was supplemented, the water drinking amount of each sheep had an increase of 60.14% compared with that of the sheep in the control period and the urination volume was 2.67 times of that of the latter, and the differences were both significant （P0.01）. The antidiuretic hormone declined by 32.59% compared with that of the sheep in the control period, with the significant difference （P 0.05）. The adrenocorticotropic hormone content increased by 81.93% compared with that of the sheep in the control period and the difference was significant （P0.01）. An increase of 28.04% （P 0.05） and 39.39% （P 0.01） was found in the contents of serum potassium and phosphorus respectively compared with that of sheep in the control period. [Conclusion] The diet with supplement of GY-01 can increase the urination volume of livestock fed with the cottonseed hulls, and the most appropriate supplement amount is 200 mg GY-01.
文摘The di-zhen (DZ) is an ancient type of acupuncture needle with a history dating back to more than 2000 years. Unlike modern acupuncture needles, the DZ is not inserted subcutaneously and is considered to be safe for common use, even at the bedside of terminally ill patients. In this case study, DZ application was selected and applied 14 times on a 92-year-old patient who had suffered severe oliguria along with administration of diuretics. Urine volume increased 12 out of 14 times following DZ treatment;however, the other two times it was ineffective. To investigate the reason and the differences in effective/ineffective DZ application, two internal conditions (effective vs ineffective) were compared by analyzing daily nursing reports (vital signs such as blood pressure, urine volume and body temperature) and weekly clinical data (including renal, liver and immune function, urea nitrogen, creatinine, ALT, AST, the ratio and number of leukocytes, erythrocytes). DZ application increased urine volume via a transient modification of the autonomic nervous system when internal homeostasis was maintained. Aging populations, who often have several diseases and medications, are rapidly increasing in developed countries. Therefore, the study and application of DZ may contribute to a reduction in medical costs, which have been rapidly and heavily expanding recently.
文摘Objective： To evaluate the influence of complete and incomplete pelvic autonomic nerve preservation （PANP） on urination function in patients with resection of rectal carcinoma. Methods： The changes of pre-and post-operative residual urine volume （RUV） in patient undergoing complete PANP （n = 15） and incomplete PANP （n = 17） were observed. Results： In fifteen cases with complete PANP, preoperative RUV was 4.09 ml, 14 days and 3 months after operation RUV were 8.00 ml and 7.02 ml （P 〉 0.05）. In seventeen cases with incomplete PANP, preoperative RUV was 3.90 ml, 14 days and 3 months after operation RUV were 36.55 ml and 22.64 ml （P 〈 0.001 ）. Conclusion： Complete and incomplete pelvic autonomic preservation may affect urination function in patients with resection of rectal carcinoma and RUV is an effective indicator if the pelvic autonomic nerves are preserved completely.

文摘This study investigates the relationship between pesticide metabolites and kidney function in solar greenhouse workers,a group with potentially higher chronic kidney disease(CKD)risk compared to general farmers.A total of 279 workers participated,with pesticide metabolites(AMPA,DMP,DEP,DMDTP,GLY,and DEDTP)measured in their urine.
文摘In Unani medicine,Bawl(urine)is recognized as a key diagnostic tool,with humoural imbalances assessed via parameters like color,consistency,sediment,clarity,froth,odor,and volume.This conceptual review explores how these classical diagnostic indicators may be contextualized alongside modern urinalysis markers(e.g.,bilirubin,protein,ketones,and sedimentation)and examined through emerging artificial intelligence(AI)frameworks.Potential applications include ResNet-18 for color classification,You Only Look Once version 8(YOLOv8)for sediment detection,long short-term memory(LSTM)for viscosity estimation,and EfficientDet for froth analysis,with standardized urine images/videos forming the basis of future datasets.Additionally,a comparative ontology is proposed to align Unani perspectives with diagnostic approaches in traditional Chinese medicine,encouraging cross-system integration.By synthesizing classical epistemology with computational intelligence,this review highlights pathways for developing AI-based decision support systems to promote personalized,accessible,and telemedicine-enabled healthcare.
文摘The Solanum genus is known for its diverse bioactive compounds,yet its diuretic potential remains understudied.This research commenced with an analysis of polyphenol and flavonoid content in Solanum elaeagnifolium leaf extract(SEFE)using colorimetric techniques,followed by HPLC-DAD to delineate its chemical composition.The aqueous extract revealed prominent constituents:naringin(12.38%),quercetin 3-O-B-D-Glucoside(27.25%),and flavone(15.26%).A 15-day study on normal rats investigated the diuretic potential of SEFE at repeated doses.SEFE significantly increased urine volume and urinary sodium/potassium levels without inducing hypokalaemia,contrasting with furosemide,a standard diuretic that induced hypokalaemia.Conversely,furosemide,a standard diuretic,increased urinary sodium and potassium while inducing hypokalaemia.It was evident that the diuretic effect of S.elaeagnifolium is dose-dependent,with a dosage of 500 mg/kg body weight exerting a more potent diuretic effect compared to furosemide.The diuretic activity of this plant was supported by an in silico study of the diuretic effect.The findings demonstrate how S.elaeagnifolium leaves have a potent diuretic impact on rats.However,more in-depth studies are needed to examine the following aspects:identifying the specific molecules responsible for the diuretic effect,understanding the molecular and cellular mechanisms underlying this activity,and assessing the long-term safety and clinical efficacy of this plant in different contexts.

文摘BACKGROUND India has the highest tuberculosis(TB)burden in the world.Of the estimated annual 10 million TB cases,features of extra pulmonary TB are evident in up to 45%.Urogenital TB(UGTB)accounts for approximately 20%of those cases.The lack of non-sputum based diagnostic tools continue to hinder efforts to reduce the burden of UGTB.MicroRNAs(miRNAs)play a crucial role in biological pathways and can be used as a potential biomarker for TB.We evaluated urinary extracellular vesicles(uEVs)as non-invasive source to explore miRNAs with biomarker potential for UGTB.AIM To evaluate the potential of miRNA-155-5p,miRNA-26a-5p and miRNA-29a-3p in uEVs to diagnose UGTB in adults.METHODS uEV characterization was done using nanoparticle tracking analysis and flow cytometry.Quantitative reverse transcriptase polymerase chain reaction(qRTPCR)for urinary uEV-miRNAs were carried out in samples from patients with suspected UGTB,or Urinary tract infections[UTI,disease controls(DC)]and healthy controls(HCs)(n=20/group).U6 was used to normalize the qRT-PCR data.Receivers operating characteristic curves was used to calculate the diagnostic accuracy of uEV-miRNAs to differentiate UGTB from controls(DC and HCs).RESULTS uEVs from UGTB or UTI patients had higher mean size,and also lower proportion of CD63 positive vesicles as compared to HC’s uEVs.Between UTI and UGTB,the mean size of uEVs was significantly higher in UTI cases.qRT-PCR analysis revealed a significantly lower abundance of miRNA-155-5p and miRNA-26a-5p in uEVs from UGTB relative to UTI(P value=0.004)and HC(P value=0.009)respectively n=20/group).While,miRNA-29a-3p was higher in abundance in both UGTB and HCs’uEV,relative to uEVs from UTI cases(P values=0.004 and 0.002 respectively,n=20/group).Moreover,miRNA-155-5p[area under curve(AUC)=0.88,P≤0.0001]and miRNA-29a-3p(AUC=0.76,P value=0.005)had optimal diagnostic accuracy to differentiate UGTB from DC(n=20/groups)with a likelihood ratio of 5.2 and 4.3,respectively through receivers operating characteristic curve.While,miRNA-155-5p(AUC=0.68,P value=0.05)and miRNA-26a-5p(AUC=0.78,P value=0.002)had optimal diagnostic accuracy to differentiate UGTB from HCs with a likelihood ratio of>2.CONCLUSION The differential expression of uEV-miRNAs,miRNA-155-5p and miRNA-29a-3p in UTGB and UTI cases hold promise in the specific diagnosis of UGTB.Further studies in large cohort are,however,needed to confirm the diagnostic accuracy of these uEV-miRNAs.

文摘Background The prolificacy of sows(litter size at birth)has markedly increased,leading to higher post-natal mor-tality.Heat stress can exacerbate this issue.Arginine plays an important role in several physiological pathways;its effect on gestating sows can depend on the period of supplementation.This study evaluated the effects of arginine supplementation on the productive performance and physiological status of sows during different gestation periods and seasons,using a multi-omics approach.Methods A total of 320 sows were divided into 4 groups over 2 seasons(warm/cold);a control group(CO)received a standard diet(including 16.5 g/d of arginine)and 3 other groups received the standard diet supplemented with 21.8 g/d of arginine(38.3 g/d of arginine)either during the first 35 d(Early35),the last 45 d(Late45)or through-out the entire gestation period(COM).The colostrum was analyzed for nutritional composition,immunoglobulins and metabolomic profile.Urine and feces were analyzed on d 35 and 106 for the metabolomic and microbial profiles.Piglet body weight and mortality were recorded at birth,d 6,d 26,and on d 14 post-weaning.Results Interactions between arginine and season were never significant.The Early35 group had a lower percent-age of stillborn(P<0.001),mummified(P=0.002)and low birthweight(LBW)piglets(P=0.02)than the CO group.The Late45 group had a lower percentage of stillborn piglets(P=0.029)and a higher percentage of high birthweight piglets(HBW;P<0.001)than the CO group.The COM group had a higher percentage of LBW(P=0.004)and crushed piglets(P<0.001)than the CO group.Arginine supplementation modifies the metabolome characterization of colos-trum,urine,and feces.Creatine and nitric oxide pathways,as well as metabolites related to microbial activity,were influenced in all matrices.A slight trend in the beta diversity index was observed in the microbiome profile on d 35(P=0.064).Conclusions Arginine supplementation during early gestation reduced the percentage of stillborn and LBW piglets,while in the last third of pregnancy,it favored the percentage of HBW pigs and reduced the percentage of stillbirths,showing that arginine plays a significant role in the physiology of pregnant sows.
文摘Cowpea, Vigna unguiculata (L.) Walp. is an economically important seed legume that helps combat food and nutrition insecurity in the Sahel, particularly Niger. However, its yield remains low due to insect pest attacks. This study was conducted at a station and in seven villages in the Maradi and Tahoua regions. It aimed to test the effectiveness of neem seed biopesticides [Azadirachta indica A. Juss] and sanitized human urine for integrated insect pest management. The cowpea variety UAM09 1055-6 was used for the experiments. The experimental trial was a Fisher block design consisting of five treatments: neem oil, neem seed extract (NSE), hygienized human urine (HHU), chemical pesticide, and a control, replicated five times at the station and twice in farmers’ environments. The study shows that Megalurothrips sjostedti Trybom, Clavigralla tomentosicollis Stål and Maruca vitrata Fabricius are the main insect pests. Plots treated with synthetic pesticides were the least infested by C. tomentosicollis. They were followed by neem seed extract and HHU treatments, which recorded an infestation level of 2.44 and 20.5 times lower than controls at the station and in farming environments. The density of thrips was 1.06 to 32.6 times lower in treated plots compared to controls. The proportion of pods damaged by M. vitrata was 1.95, 2.55, and 2.77 times lower in plots treated with HHU, NSE, and synthetic pesticide, respectively, compared to controls. Grain yields were 1.80 and 2.62 times higher in UHH and NSE treatments compared to control plots, both at the station and in farmers’ environments. A yield increase of 44.58% and 61.92% was noted for these treatments at the station and in farmers’ environments, respectively. These results may promote the dissemination of NSE and HHU biopesticide technologies in rural areas as an alternative method for integrated pest management of cowpeas.

文摘The objectives of this study which included two experiments were to investigate the effects of dietary inclusion of sorghum grain rich in condensed tannins(CT)(18.9 g kg^(–1)dry matter(DM))on nitrogen(N)metabolism and urine nitrous oxide(N_(2)O)emissions of beef steers.In experiment 1,six Limousin×Luxi crossbreed steers with an initial liveweight of(245.0±18.7)kg were used as experimental animals.Three levels of sorghum grain,i.e.,0,167 and 338 g kg^(–1)DM were included in diets as experimental treatments.The animals and the treatments were randomly assigned to a replicated 3×3 Latin square design.In experiment 2,static incubation technique was used to determine the N_(2)O emissions of the urine samples collected in experiment 1.The results of experiment 1 showed that dietary inclusion of sorghum grain linearly increased the faecal N excretion(P=0.001),the total N excretion(P=0.010)and the faecal N to N intake ratio(P=0.021),but it did not affect the N retention and the N utilization efficiency(P>0.10).The plasma metabolomic data showed that dietary inclusion of sorghum grain increased the relative concentrations of phenolic acid(N1,N5,N10-tris-trans-p-coumaroylspermine and prenyl cis-caffeate)and carnitine(3-hydroxyisovalerylcarnitine and linoelaidyl carnitine).The results also showed that dietary inclusion of sorghum grain linearly increased the urinary urea excretion(P=0.010)and decreased the urinary excretion of purine derivatives(P=0.041)as well as the estimated rumen microbial N supply(P=0.012)based on urinary purine derivatives.The results of experiment 2 showed that including sorghum grain in the diet linearly increased the average concentrations of NH_(4)^(+)-N(P=0.012),NO_(2)^(–)-N(P=0.009),NO_(3)^(-)-N(P=0.001)and the total inorganic N(P<0.001)in the soil enriched with urine samples.The urine sample N_(2)O-N flux(P=0.001),the estimated steer urine N_(2)O-N flux(P=0.021)and the N_(2)O-N to urinary N ratio(P=0.038)linearly increased with increasing inclusion of sorghum grain in the diet.In conclusion,dietary inclusion of sorghum grain containing high CT at 167 and 338 g kg^(–1)DM did not affect the N utilization efficiency of steers but increased the urine N_(2)O-N emissions by 5.7 and 31.4%,respectively.For reducing the N_(2)O emissions to the environment,high levels of sorghum grain should not be included in the diet of steers.

文摘Personal care products(PCPs)are a class of emerging pollutants that have attracted public concern owing to their harmful effects on humans and the environment.Biomonitoring data is valuable for insight the levels of PCPs in the human body and can be crucial for identifying potential health hazards.To gain a better understanding of timely exposure profiles and health risk of reproductive-age population to PCPs,we determined six parabens,six benzophenone-type ultraviolet filters,and three disinfectants in 256 urine samples collected from young adults aged 18-44 years in Beijing,China.The urinary levels of benzophenone-3(BP-3)and 4-hydroxybenzophenone(4-OHBP)were significantly higher in summer compared to winter,suggesting these compounds have different seasonal usage patterns.Moreover,the total concentration of 15 PCPs in female was 430 ng/mL,approximately two times higher than that in male.P-chloro-m-xylenol(PCMX),as a new type of antibacterial agent,has the greatest level among all target analytes,indicating the increasingly use of this antibacterial alternative recently.Five potential influencing factors that lead to the elevated exposure level of PCPs were identified.Over 19%of the target population had a high hazard index value(greater than 1)which was attributed to exposure to propyl paraben(PrP),benzophenone-1(BP-1),BP-3 and PCMX,indicating that PCPs may pose a relatively high exposure risk at environmental levels that should be a cause for concern.

文摘BACKGROUND Endoscopic ultrasound-guided biliary drainage,including endoscopic ultrasoundguided choledochoduodenostomy and endoscopic ultrasound-guided hepatogastrostomy(EUS-HGS),is an efficacious alternative to endoscopic retrograde cholangiopancreatography and its common complications are bile leak,infection,stent migration and bleeding.Here,we report an atypical case of a patient who developed unexplained dark green urine after receiving EUS-HGS,which we suspected to be caused by an abnormal biliary-vascular fistula.CASE SUMMARY A 76-year-old woman diagnosed with pancreatic adenocarcinoma received EUSHGS for relieving jaundice.The patient reported abdominal pain and chest tightness after the operation,with difficulty in urinating.X-ray suggested rightsided pleural effusion and dark green pleural effusion was drained out.However,the patient also developed dark green urine,which appeared everyday afternoon and disappeared automatically after intravenous treatment.The previous pleural effusion disappeared after one week,but later the patient showed an increase of ascites,and the lesions were compartmentalized and encapsulated internally.CONCLUSION Postoperative surveillance after EUS-HGS must be emphasized to check for in order to prevent severe and hidden complications.
文摘The advent of precision medicine has underscored the importance of biomarkers in predicting therapy response for bladder cancer,a malignancy marked by considerable heterogeneity.This review critically examines the current landscape of biomarkers to forecast treatment outcomes in bladder cancer patients.We explore a range of biomarkers,including genetic,epigenetic,proteomic,and transcriptomic indicators,from multiple sample sources,including urine,tumor tissue and blood,assessing their efficacy in predicting responses to chemotherapy,immunotherapy,and targeted therapies.Despite promising developments,the translation of these biomarkers into clinical practice faces significant challenges,such as variability in biomarker performance,the necessity for large-scale validation studies,and the integration of biomarker testing into routine clinical workflows.We also highlight the need for standardized methodologies and robust assays to ensure consistency and reliability.Future directions point towards longitudinal studies and the development of combination biomarker panels to enhance predictive accuracy.This review emphasizes the transformative potential of predictive biomarkers in improving patient outcomes and advocates for continued collaborative efforts to overcome existing barriers in this rapidly evolving field.

文摘Non-ferrous metal smelting poses significant risks to public health.Specifically,the copper smelting process releases arsenic,a semi-volatile metalloid,which poses an emerging exposure risk to both workers and nearby residents.To comprehensively understand the internal exposure risks of metal(loid)s from copper smelting,we explored eighteen metal(loid)s and arsenic metabolites in the urine of both occupational and non-occupational populations using inductively coupled plasma mass spectrometry with high-performance liquid chromatography and compared their health risks.Results showed that zinc and copper(485.38 and 14.00μg/L),and arsenic,lead,cadmium,vanadium,tin and antimony(46.80,6.82,2.17,0.40,0.44 and 0.23μg/L,respectively)in workers(n=179)were significantly higher compared to controls(n=168),while Zinc,tin and antimony(412.10,0.51 and 0.15μg/L,respectively)of residents were significantly higher than controls.Additionally,workers had a higher monomethyl arsenic percentage(MMA%),showing lower arsenic methylation capacity.Source appointment analysis identified arsenic,lead,cadmium,antimony,tin and thallium as co-exposure metal(loid)s from copper smelting,positively relating to the age of workers.The hazard index(HI)of workers exceeded 1.0,while residents and control were approximately at 1.0.Besides,all three populations had accumulated cancer risks exceeding 1.0×10^(-4),and arsenite(AsIII)was the main contributor to the variation of workers and residents.Furthermore,residents living closer to the smelting plant had higher health risks.This study reveals arsenic exposure metabolites and multiple metals as emerging contaminants for copper smelting exposure populations,providing valuable insights for pollution control in non-ferrous metal smelting.
文摘Objective:To explore the predictive value of the combined test of urinary sodium,urinary potassium excretion fraction(FEK),and urinary potassium concentration/urine creatinine concentration(UK/UCr)in sepsis-induced early acute kidney injury(AKI).Methods:Sixty sepsis patients admitted to the Northern Hospital of National Pharmaceuticals from 2022.4 to 2024.4 were selected and divided into the AKI group(n=21)and the non-AKI group(n=39)according to whether AKI occurred or not,and another 20 health check-up subjects from our hospital were selected to be included in the control group during the same period of time,and we compared the urinary sodium,urinary FEK,and urinary UK/UCr tests of the three groups,and analysed the urinary potassium concentration/urine creatinine concentration(UK/UCr)in the early stage of sepsis-induced acute kidney injury(AKI)by plotting the working characteristics of the subjects(ROC)curve graph to analyse the predictive value of the combined detection of urinary sodium,urinary FEK and urinary UK/UCr in sepsis-induced early AKI.Results:The levels of urinary FEK and urinary UK/UCr in the non-AKI group were higher than those in the control group,and the levels of urinary sodium were lower than those in the control group(P<0.05),while the levels of urinary FEK and urinary UK/UCr in the AKI group were higher than those in the non-AKI group,and the levels of urinary sodium were lower than those in the non-AKI group(P<0.05);the ROC was plotted and found that the combined test of urinary sodium,urinary FEK,and urinary UK/UCr was useful for the prediction of early AKI caused by sepsis.The area under the curve(AUC)values ranged from 0.694-0.940,with high sensitivity and specificity,and the value of predicting sepsis-induced early AKI was high.Conclusion:Urinary sodium,urinary FEK and urinary UK/UCr can be used as effective biomarkers for the early prediction of AKI,and the combined test has high value in predicting early AKI caused by sepsis.
文摘To evaluate the subchronic and chronic toxicity of Fuyanxiao capsules,Sprague-Dawley(SD)rats were used in toxicity studies.In the subchronic toxicity study,50 female rats were randomly divided into a high-dose group(5.4g/kg/day)and a control group,with 15 rats in each,and medium(2.7g/kg/day)and low(1.35g/kg/day)dose groups,with 10 rats in each.The test substance was administered orally(mixed with feed,twice daily)for 90 consecutive days.In the chronic toxicity study,40 female rats were randomly divided into high,medium,and low dose groups and a control group,with 10 rats in each.The test substance was administered orally in the same manner for 180 consecutive days.Clinical signs,body weight,and food consumption were observed and recorded daily.At the end of the terminal phase(the first 10 rats from each group,1 day after the last dose)and the recovery phase(the last 5 rats from the control group and the high-dose group,observed for an additional 28 days after the last dose),blood and urine samples,as well as organs,were collected.Organ coefficients were calculated,and various hematological and urinary indicators were detected,followed by pathological analysis.The results showed that there were no significant differences in body weight,food consumption,or organ coefficients between any of the dose groups and the control group in both subchronic and chronic toxicity studies(P>0.05).Histopathological examination revealed no lesions,suggesting no tissue or organ damage in any of the dose groups.The rats exhibited good mental status,and hematological and urinary physiological indicators were within normal ranges,indicating stable liver and kidney function,hematopoietic system of the bone marrow,and internal environment in all dose groups.Therefore,Fuyanxiao capsule has no obvious subchronic or chronic toxicity in SD rats,and it is safe and reliable to use at reasonable dosage in clinical practice.
