Objective To investigate the effects of pretreatment with Xuebijing injection on renal tubular injury in rats with contrast-induced acute kidney injury(CI-AKI).Methods Twenty-four Sprague-Dawley(SD)rats were selected and divided into normal group,model group,control group,and treatment group according to the random number table method,with 6 rats in each group.The animal model of CI-AKI was prepared by adopting iohexol,and the normal group was not subjected to any treatment.The rats in the treatment group were injected with Xuebijing injection via the tail vein 15 hours before modeling until 24 hours after modeling.The injection volume was 10 mL/kg for every 6 hours.The control group was injected with normal saline at the same time point.After 24 hours of modeling,the urine of rats in each group was collected to determine the levels of blood urea nitrogen(BUN)and urine N-acetyl-β-D-gluco-aminidase(uNAG),and the blood was collected to determine the levels of serum creatinine(SCr).Then the rats were killed and the kidney tissues were extracted,and then stained with hematoxylin-eosin(HE),and the pathological changes of the kidney tissues were observed under the light microscope.Results BUN,SCr and uNAG were significantly higher in the model group than those in the normal group[BUN(μmol/L):37.29±6.18 vs.6.37±1.19,SCr(mmol/L):30.43±4.44 vs.14.90±1.61,uNAG(U/L):47.77±4.71 vs.11.32±3.62,all P<0.01];BUN,SCr and uNAG levels were obviously decreased in the treatment group compared to the model group[BUN(μmol/L):9.45±3.04 vs.37.29±6.18,SCr(mmol/L):19.83±2.16 vs.30.43±4.44,uNAG(U/L):21.70±6.21 vs.47.77±4.71,all P<0.05],however,BUN and uNAG in the treatment group were still significantly higher than those in the normal group[BUN(μmol/L):9.45±3.04 vs.6.37±1.19,uNAG(U/L):21.70±6.21 vs.11.32±3.62,P<0.05 or P<0.01];SCr in the treatment group was not statistically significant compared to the normal group(μmol/L:19.83±2.16 vs.14.90±1.61,P>0.05).Under the light microscope,the renal tubular epithelial cells at the junction of cortex and dermatomedulla in the kidneys of the model group were obviously vacuolated,accompanied by cell detachment and necrosis,and the tubules were dilated,with no obvious lesions in the glomeruli.The degree of damage in the control group and the treatment group was reduced compared with that in the model group.The degree of renal tubular damage in the model group was higher than that in the normal group;while the degree of renal tubular damage in the control group was significantly lower than that in the model group;and the degree of renal tubular damage in the treatment group was lower than that in the model group.There was no statistically significant difference in the degree of renal tubular damage between the treatment group and the control group.Conclusion Xuebijing injection may exert a protective effect on renal function in rats with CI-AKI by attenuating renal tubular injury.

Ginseng Radix et Rhizoma（GRR） has the function of replenishing vital energy and can lighten the body and prolong the life when taken for a long time， which is suitable for the development of anti-aging products， so this paper intends to sort out the progress of anti-aging research on GRR. After combing， the results of modern studies have shown that a variety of components in GRR have anti-aging effect， which can prolong the lifespan of aging animal models， as well as delay the aging of various systems. The anti-aging mechanisms mainly include anti-cellular senescence， anti-oxidative stress， inhibiting telomere shortening， maintaining mitochondrial homeostasis and so on. The anti-aging ingredients of GRR involved in the researches mainly include ginsenoside Rg₁ and ginsenoside Rb₁， in addition， ginsenoside Rg₃， ginsenoside Rd， ginsenoside Rg₂， ginsenoside Re， ginsenoside Rb₂， oligosaccharides of GRR， polysaccharides of GRR， water extract of GRR， total saponins of Panax ginseng stems and leaves are also included. Therefore， under current background of population aging， the in-depth development of GRR and its transformation into anti-aging products are of great significance for delaying senility and improving the health conditions of aging population.

Objectives:To evaluate the tricuspid valve(TV)geometric remodeling in patients with idiopathic pulmonary arterial hypertension(IPAH)by three-dimensional transthoracic echocardiography. Methods:Two-dimensional and three-dimensional transthoracic echocardiography were performed in 30 IPAH patients and 15 healthy controls,and the geometry parameters of TV were obtained by four-dimensional auto tricuspid valve quantitative(4D Auto-TVQ)in the right ventricular-focused apical view.Pulmonary arterial hypertension was determined by right heart catheterization within 48 hours of echocardiography. Results:The 4-chamber diameter,tricuspid annular(TA)perimeter,TA area,maximal tenting height,coaptation point height and tenting volume were larger in IPAH patients than those in healthy controls(all P＜0.05),2-chamber diameter was similar between two groups.In IPAH group,maximal tenting height and coaptation point height were moderately correlated with right ventricular end-diastolic volume(r=0.710,r=0.515,both P＜0.05),while TA perimeter,4-chamber diameter and TA area were moderately correlated with right atrial end-systolic volume(r=0.712,r=0.558,r=0.545,all P＜0.05). Conclusions:IPAH patients have larger maximal tenting height,coaptation point height and tenting volume,TA enlargement is mainly visible in 4-chamber diameter.TV tenting height is associated with right ventricular volume,but TA size is associated with right atrial volume in IPAH patients.

Objective:To examine the impact of varied surgical treatment strategies on the prognosis of patients with initial resectable gastric cancer liver metastases (IR-GCLM).Methods:This is a retrospective cohort study. Employing a retrospective cohort design, the study selected clinicopathological data from the national multi-center retrospective cohort study database, focusing on 282 patients with IR-GCLM who underwent surgical intervention between January 2010 and December 2019. There were 231 males and 51 males, aging ( M(IQR)) 61 (14) years (range: 27 to 80 years). These patients were stratified into radical and palliative treatment groups based on treatment decisions. Survival curves were generated using the Kaplan-Meier method and distinctions in survival rates were assessed using the Log-rank test. The Cox risk regression model evaluated HR for various factors, controlling for confounders through multivariate analysis to comprehensively evaluate the influence of surgery on the prognosis of IR-GCLM patients. A restricted cubic spline Cox proportional hazard model assessed and delineated intricate associations between measured variables and prognosis. At the same time, the X-tile served as an auxiliary tool to identify critical thresholds in the survival analysis for IR-GCLM patients. Subgroup analysis was then conducted to identify potential beneficiary populations in different surgical treatments. Results:(1) The radical group comprised 118 patients, all undergoing R0 resection or local physical therapy of primary and metastatic lesions. The palliative group comprised 164 patients, with 52 cases undergoing palliative resections for gastric primary tumors and liver metastases, 56 cases undergoing radical resections for gastric primary tumors only, 45 cases undergoing palliative resections for gastric primary tumors, and 11 cases receiving palliative treatments for liver metastases. A statistically significant distinction was observed between the groups regarding the site and the number of liver metastases (both P<0.05). (2) The median overall survival (OS) of the 282 patients was 22.7 months (95% CI: 17.8 to 27.6 months), with 1-year and 3-year OS rates were 65.4% and 35.6%, respectively. The 1-year OS rates for patients in the radical surgical group and palliative surgical group were 68.3% and 63.1%, while the corresponding 3-year OS rates were 42.2% and 29.9%, respectively. A comparison of OS between the two groups showed no statistically significant difference ( P=0.254). Further analysis indicated that patients undergoing palliative gastric cancer resection alone had a significantly worse prognosis compared to other surgical options ( HR=1.98, 95% CI: 1.21 to 3.24, P=0.006). (3) The size of the primary gastric tumor significantly influenced the patients′ prognosis ( HR=2.01, 95% CI: 1.45 to 2.79, P<0.01), with HR showing a progressively increasing trend as tumor size increased. (4) Subgroup analysis indicates that radical treatment may be more effective compared to palliative treatment in the following specific cases: well/moderately differentiated tumors ( HR=2.84, 95% CI 1.49 to 5.41, P=0.001), and patients with liver metastases located in the left lobe of the liver ( HR=2.06, 95% CI 1.19 to 3.57, P=0.010). Conclusions:In patients with IR-GCLM, radical surgery did not produce a significant improvement in the overall prognosis compared to palliative surgery. However, within specific patient subgroups (well/moderately differentiated tumors, and patients with liver metastases located in the left lobe of the liver), radical treatment can significantly improve prognosis compared to palliative approaches.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).
