Uarthritis is a common inflammatory arthritis, which has been well known as the White Tiger arthritis in traditional Chinese medicine. This article discussed the pathogenesis of blood stasis and the related studies in hyperuricemia, acute and chronic phase of Uarthritis. It suggested that blood stasis is a crucial pathogeny of uarthritis. Thus, the chinese herb medicine of blood circulation drugs should beapplied in all the phases of Uarthritis.

Objective To explore the effect on prognosis of attenuated plaque (AP)in patients with acute coronary syndrome (ACS)after percutaneous coronary intervention(PCI).Methods This study was a prospective study which included 225 ACS patients who admitted to the cardiology and met the conditions between January 2009 and December 2011.Clinical data,intravascular ultrasound characteristics of plaque, blood flow in coronary angiography and cardiovascular complications within 30 days after PCI were recorded.The main form of follow-up was telephone follow-up,supplemented by patient follow-up and out-patient follow-up.Endpoint was major adverse cardiac events (MACE).Kaplan-Meier method was used to estimate survival rate.The survival difference between the two groups was compared using the Log-Rank test.Results Extravascular elastic membrane area (EEMA),plaque area (PA),plaque burden,remodeling index in AP group were significantly increased than those in non-AP group.Corrected TIMI frame count (CTFC)immediately after the balloon dilatation was significantly higher in AP group than in non-AP group. Recent overall complications were more frequently documented in AP group than in non-AP group,but long-term follow-up outcome of MACE-free survival curves showed no significant difference between the two groups.Conclusions Recent prognosis,not long-term prognosis,is affected by attenuated plaque in ACS patients after PCI,which help to stratify risk further and guide treatment in ACS patients.

Objective:This study aims to investigate the incidence, risk factors, and prognosis of acute kidney injury after heart transplantation.Methods:Clinical data of 180 recipients of heart transplantation at Zhengzhou Seventh People's Hospital from April 2018 to November 2022 are retrospectively analyzed. According to whether AKI occurred 7 days after surgery, the recipients are divided into a non AKI group(85 cases)and an AKI group(95 cases). The baseline data, general perioperative conditions, and clinical data of the two groups of recipients are compared using chi square test and rank sum test to identify possible influencing factors for AKI after heart transplantation.Determine independent risk factors through binary logistic regression.The Kaplan Meier method is used to draw survival curves to further clarify the impact of AKI on the survival and cumulative hospitalization of heart transplant recipients.Results:The incidence of postoperative AKI in 180 recipients of this study is 52.7%(95/180). Univariate analysis showed that there are statistically significant differences in recipient age, preoperative albumin, platelet count, graft cold ischemia time, and surgical time between the AKI group and the non AKI group(all P<0.05). Further multivariate analysis showes that recipient age( OR=1.021, 95% CI: 1.001~1.043, P=0.043), surgical time( OR=1.005, 95% CI: 1.001~1.008, P=0.005), platelet count( OR=0.995, 95% CI: 0.990~1.000, P=0.034), and donor cold ischemia time ( OR=0.996, 95% CI: 0.993~0.996, P=0.004)are independent risk factors for AKI after heart transplantation. Prognostic analysis showed that 35.7%(25 cases)of the AKI group received continuous renal replacement therapy(CRRT)after surgery, and 31.9%(23 cases) received aortic balloon counterpulsation(IABP)after surgery. Compared with 0 and 8.9%(7 cases)of the AKI group without AKI, the differences are statistically significant(all P<0.01). Compared with the non AKI group, the invasive mechanical ventilation time is 614 (504, 707) hours and 540 (460, 610) hours( P<0.01), the stay time in the intensive care unit is 12(8, 16)days and 10(6, 15)days( P=0.050), and the estimated glomerular filtration rate(eGFR)on the 7th day after surgery is 10(6, 15)ml/(min·1.73 m 2)and 68(57.5, 91.0)ml/(min·1.73 m 2)( P<0.01), with statistical significance. The cumulative survival rate of the AKI group after heart transplantation is lower than that of the non AKI group, and the cumulative hospitalization rate Is higher than the latter. The differences between the groups are statistically significant(all P<0.01). Conclusions:The incidence of AKI after heart transplantation is relatively high, and recipient age, platelet count, graft cold ischemia time, and surgical time are independent risk factors for AKI. Recipients with AKI after heart transplantation have a higher proportion of postoperative use of CRRT and IABP, longer invasive mechanical ventilation time and monitoring room stay time, and lower eGFR on the 7th day after surgery; at the same time, recipients with AKI after heart transplantation have a lower postoperative survival rate and a higher cumulative hospitalization rate.

OBJECTIVETo study the chemical constituents of Swertia macrosperma.

METHODThe air-dried whole plants of Swertia macrosperma were extracted with boiling water. The extract was concentrated to a small amount of volume and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isolated and purified by column chromatography from the EtOAc fraction, and identified based on spectral analyses (MS, 1H-NMR, 13C-NMR).

Objective:To explore the risk factors for early mortality in heart transplant(HT)recipients and construct a nomogram prediction model.Methods:From 2018 to 2022, preoperative clinical data were retrospectively reviewed for 163 consecutive HT recipients.Risk factor variables were shortlisted by univariate correlation analysis based upon early(90-day)postoperative patient survival.Lasso regression was then employed for screening all variables and common variables were combined.A nomogram was constructed for predicting the probability of early mortality after considering actual circumstance.Receiver operating characteristic(ROC)curve, area under the ROC curve(AUC), Harrell's C-index and calibration curves were employed for evaluating and internally validate the performance of the model.Decision curve analysis was performed for assessing clinical utility of the model.Results:In survival and mortality groups, mechanical ventilation, nervous system lesions, use of extracorporeal membrane oxygenation, red blood cell count ≤3.52×10 12/L, mean pulmonary arterial pressure>27 mmHg, pulmonary vascular resistance>4.01 Wood Unit, albumin≤33 g/L, aspartate aminotransferase >50 U/L, hemoglobin ≤108 g/L, platelet count ≤109×10 9/L and total bilirubin>57 μmol/L demonstrated statistically significant differences( P<0.05). At the same time, according to actual situations and different variables, hemoglobin ≤108 g/L, albumin ≤33 g/L, platelet count ≤109×10 9/L, total bilirubin>57μmol/L, aspartate aminotransferase>50 U/L, nervous system lesions and average pulmonary arterial pressure >27 mmHg were seven variables.And a nomogram with relatively high reliability was constructed for predicting the probability of early mortality post-HT(nomogram model evaluation, AUC 0.917, C index 0.910 and good calibration curve). Decision curve analysis indicated that the nomogram could benefit HT recipients. Conclusions:Risk factors have been identified for early mortality in HT recipients.And the nomogram prediction model offers a simple and reliable tool for predicting early mortality post-HT.It has important implications for individualized treatment of HT candidates.
