The study utilized spectral correlation analyses combined with bioactivity evaluation to examine the effective components of antidepressants in the Baihe Dihuang decoction. Firstly, the chemical fingerprints for different extraction parts in the Baihe Dihuang decoction were achieved using HPLC and UHPLC-MS technology. Then, in order to evaluate the antidepressant effect of Baihe Dihuang decoction, the animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Hunan University of Chinese Medicine (No. LLBH-202104270001), in compliance with the Institutional Animal Care Guidelines. We recorded the distance of autonomous movement of mice in open field experiment, the immobility time of tail suspension test, and the forced swimming. Additionally, we measured the content of neurotransmitters. Finally, Pearson analysis, grey correlation analysis, and orthogonal partial least squares regression analysis were utilized to establish the correlation between antidepressant efficacy indicators and fingerprinting. The spectrum-effect relationship results were confirmed through the in vitro activity verification. This study demonstrated that regaloside A, B, C, catalpol, and Isoacteoside might be the main antidepressant components in Baihe Dihuang decoction. Furthermore, it was found that using diverse mathematical models and bioactivity evaluation could enhance the accuracy of the spectral correlation analyses results.

It is difficult to insert long-term dialysis catheters after severe stenosis or occlusion of the internal jugular vein and innominate vein. We used REcanalisation and balloon-oriented puncture for Re-insertion of dialysis catheter in nonpatent central veins (REBORN) in seven patients with severe central venous lesions, and all patients were inserted with long-term dialysis catheters successfully. None had severe complications such as pneumothorax, hemothorax, or pulmonary embolism during operation. All catheters functioned well after postoperative follow-up of 2 months. REBORN provides a novel approach to establish difficult dialysis pathways.

Objective:To explore the clinical efficacy of adult donor dual kidney transplantation.Methods:Retrospective analysis of case data of 13 adult donor kidney dual kidney transplantation (DKT) performed in the The Second Xiangya Hospital of Central South University from September 2016 to December 2020. For 13 donors, the average age and BMI were (53.5±12.4)years and (24.3±2.8) kg/m 2, respectively. Their mean Serum creatinine (SCr) at admission and before procurement was (132.9±54.1)and (228.7±112.4)μmol/L, respectively. 3 of them had diabetes mellitus history, and 8 had hypertension history. 11 met the United Network for Organ Sharing (UNOS) DKT criteria and 6 met Remuzzi score DKT criteria. For 13 recipients, the average age and BMI were (39.3±8.9)years and (20.2±2.4)kg/m 2, respectively. All of them received ABO blood type-matched kidney transplants. 2 of them had their grafts transplanted in the bilateral iliac. In 12 cases, the grafts filled rapidly and urinated immediately when opening blood flow. In 1 case, the grafts were dark in color and vascular showed weak pulsation after opening blood flow. The time to recovery of perioperative graft function (from the day of surgery to the natural reduction of SCr to the normal range 44-133μmol/L), the occurrence of delayed graft function (DGF), acute rejection (AR), ureteral and surgical incision complications, as well as the recipients’ final follow-up SCr, eGFR, urinary protein, and grafts outcome were observed. Risk factors affecting outcomes were assessed by univariate logistic regression analysis. Results:The SCr dropped to the normal range at discharge in 10 recipients, and the average recovery time was (13.8±13.0) days. In other 3 cases SCr at discharge were 300.0, 149.0, 152.5μmol/L. 4 cases had DGF, 4 had AR, 1 experienced urinary fistula, and 1 experienced incisional dehiscence, which were treated with anti-rejection, J-tube implantation, continuous catheterization to maintain bladder void, secondary suturing, respectively. The follow-up time ranged from 4 to 54 months, with a median of 28(15.5, 31.0) months. At the final follow-up time, 10 cases had good graft function, 2 suffered impaired kidney function, and 1 experienced graft failure. The average SCr and eGFR except for graft failure patient were (144.2±101.3)μmol/L and (52.9±21.2)ml/min, respectively. 4 had positive urine protein. Univariate logistic regression analysis showed that donor age, BMI, history of diabetes mellitus and hypertension, and SCr were not significantly correlated with recipients’ DGF and graft impairment ( P>0.05), and due to the small sample size, multifactorial logistic regression analysis was not performed. Conclusion:The short to medium-term effects of adult donor DKT coule be safe and feasible.

Objective:To investigate the correlation between the prognosis of patients infected with BK virus after renal transplantation and their peripheral blood related indexes.Methods:131 patients from the Renal Transplantation Department of the Second Xiangya Hospital of Central South University who underwent renal transplantation and firstly infected with BK virus after the surgery during the period from August 2018 to August 2021 were retrospectively analyzed. 93 males (71.0%) and 38 females (29.0%). The average age was (37.5±11.3) years old. 109 cases underwent cadaveric kidney transplant (83.2%) and 22 cases underwent relatives kidney transplant (16.8%). The onset time of the first infection with BK virus after renal transplantation was (188.7±16.6) days, and the serum creatinine was (127.5±39.5) μmol/L. 25 patients (19.1%)infected with BK virus were positive in blood and urine at the same time, and 106 patients (80.9%)infected with BK virus were positive only in urine. Among 131 patients infected with BK virus, 70 patients were treated by lowering the blood concentration of tacrolimus to enhance immunity, 12 patients were treated by switching tacrolimus to cyclosporine, and 49 patients had incomplete follow-up data. The DNA load of BK virus in 25 patients [5.6(2.4, 12.3)×10 3copies/ml] positive in blood, white blood cell count(WBC)(5.8±2.0)×10 9/L, hemoglobin(Hb)(122.0±22.4)g/L, platelet count(PLT)(187.1±63.1)×10 9/L, neutrophil count(NEUT)(3.9±1.7)×10 9/L, lymphocyte count(LYM)(1.5±0.8)×10 9/L, monocyte count(MONO)(0.4±0.2)×10 9/L, neutrophil to lymphocyte ratio(NLR)2.2(1.7, 3.5), derived neutrophil to lymphocyte ratio(dNLR)1.7(1.3, 2.6), platelet to lymphocyte ratio(PLR)121.3(86.3, 227.3), monocyte to lymphocyte ratio(MLR)0.2(0.1, 0.4) and lymphocyte to monocyte ratio(LMR)4.7±2.6. The DNA load of BK virus in 106 patients [20.4(0.4, 2 570.0)×10 5copies/ml] positive in urine, WBC 6.6(4.8, 9.1)×10 9/L, Hb(129.0±24.5)g/L, PLT 188.0(147.3, 226.5)×10 9/L, NEUT 4.6(3.0, 6.6)×10 9/L, LYM(1.7±0.8)×10 9/L, MONO 0.4(0.3, 0.5)×10 9/L, NLR 2.8(1.9, 3.9), dNLR 2.1(1.5, 3.0), PLR 120.5(87.0, 163.2), MLR 0.2(0.1, 0.4), LMR 4.5(2.8, 6.7). 70 patients infected with BK virus treated by lowering the blood concentration of tacrolimus were divided into BK virus rise group and BK virus decline group according to the change of BK virus DNA load in blood and urine before and after treatment (the grouping principle of this study gives priority to the change of BK virus DNA load in blood, followed by the change of BK virus DNA load in urine). The WBC, Hb, PLT, NEUT, LYM, MONO, NLR, dNLR, PLR, MLR, LMR, tacrolimus blood concentration and change difference, blood creatinine and change difference were analysed between two groups. Results:The BK virus DNA load in 25 patients positive in blood was correlated with NLR and dNLR ( r=0.5062, P=0.0098; r=0.5738, P=0.0027), and there was no correlation between the BK virus DNA load in blood with the WBC ( r=-0.0185, P=0.9302), Hb ( r=0.0912, P=0.6646), PLT ( r=-0.3931, P=0.0519), NEUT ( r=0.2438, P=0.2401), LYM ( r=-0.3035, P=0.1402), MONO ( r=-0.3279, P=0.1096), PLR( r=0.1054, P=0.6161), MLR( r=0.0738, P=0.7257), LMR( r=-0.0738, P=0.7257).

As for 70 patients infected with BK virus, there were 37 patients in the BK virus rise group and 33 patients in the BK virus decline group. In the two groups, age [(38.4±12.0)years old and(39.0±9.0)years old], gender [male /female: (23/14) cases and(27/6)cases], blood type [A+ /B+ /AB+ : (22/13/20)cases and (26/6/1)cases], donation type [relatives donnation/cadaveric donation: (29/8)cases and (27/60)cases], blood creatinine(after treatment)[123.0(98.4, 140.5)μmol/L and 132.0(107.1, 162.4)μmol/L] and change difference before and after treatment [0(-15.7, 10.5)μmol/L and -2.0(-9.1, 15.0)μmol/L], tacrolimus blood concentration (after treatment)[(6.7±2.0)ng/ml and(6.5±1.5)ng /ml] and tacrolimus concentration change difference [-1.4(-3.8, 0.6)ng/ml and -1.2(-2.2, 1.3)ng/ml] had no significant difference( P<0.05). The MONO of the two groups was statistically different [0.3(0.2, 0.5)×10 9/L and 0.4(0.3, 0.6)×10 9/L, P=0.033], and there was no difference between the two groups in WBC[6.6(4.1, 8.8)×10 9/L and 6.8(5.4, 8.9)×10 9/L], Hb[(133.2±25.3)g/L and(131.6±20.6)g/L], PLT[185.0(151.0, 231.5)×10 9/L and 196.0(149.0, 234.0)×10 9/L], NEUT[4.3(2.4, 6.4)× 10 9/L and 4.2(3.1, 5.5)×10 9/L], LYM[1.7(1.1, 2.2)×10 9/L and 1.8(1.1, 2.3)×10 9/L], NLR[2.5(1.9, 3.8)and 2.4(1.9, 3.7)], dNLR [2.0(1.5, 2.8)and 1.9(1.4, 2.5)], PLR [114.9(85.1, 159.4)and 111.3(77.1, 159.6)], LMR(4.6±2.6 and 5.2±2.4), MLR[0.2(0.2, 0.4)and 0.2(0.2, 0.4)]( P<0.05). Conclusions:There is a positive correlation between the blood BK virus DNA load and NLR, dNLR in renal transplant recipients infected with BK virus. The rise of MONO correlates with good prognosis of BK virus.

Chronical hyperuricemia, a severe metabolic disease characterized by increased serum uric acid, urea nitrogen, and creatinine, has a positive correlation with the risks of gouty arthritis, diabetes, hypertension, and kidney damage. Abnormal purine metabolism and reduced uric acid excretion are the major causes of hyperuricemia, which, thus, points to a potential strategy of preventing from or delaying the progress of hyperuricemia-related diseases and its complications by effectively controlling the serum uric acid level. Increasing evidence has revealed that Chinese medicines alleviate hyperuricemia through regulating intestinal flora, which plays a pivotal role in regulating metabolites, including uric acid level. The disease treatment with traditional Chinese medicine is based on syndrome differentiation, and Chinese medicines often have multiple effects and a wide range of targets. In this review, we summarized the anti-hyperuricemia effects and mechanisms of active compounds in Chinese medicines, single Chinese medicinal herbs, and Chinese medicinal prescriptions in regulating the uric acid level via intestinal flora and metabolites, which will be helpful for further study and application of Chinese medicines in hyperuricemia treatment.

Most of the active ingredients of herbs are secondary metabolites of plants. Cytochrome P450s (P450s) are hemoglobin-containing monooxygenases encoded by a super-gene family, which play important roles in the metabolic network of plants. This review focuses on the role of P450s on biosynthesis of secondary metabolites such as terpenoids, alkaloids, flavonoids and phenylpropanoids. This will provide references for biosynthesis and regulation of secondary metabolites in medicinal plants.

Objective To explore the correlation of disease activity with the primary syndromes of deficiency and excess types of lupus nephritis(LN). Methods A retrospective study was carried out in 134 LN patients,and the LN patients were differentiated into deficiency syndrome(deficiency group)and excess syndrome(excess group). The disease activity related indicators of systemic lupus erythematosus disease activity index(SLEDAI)scores, complements, inflammation indexes, and urine indicators were compared between the two groups. Results Of the 134 LN patients,33 cases were differentiated into excess syndrome,and 101 cases were differentiated into deficiency syndrome. According to the SLEDAI scores, 9.09％ of the patients in excess group were inactive, 4.95％ of the patients in deficiency group were inactive, and most of the patients in the two groups were at severe active stage. There was no significant difference of SLEDAI scores between the two groups(P>0.05) . The differences of complement C3 and C4 , inflammation indexes of C-reactive protein(CRP)and erythrocyte sedimentation rate(ESR),urine protein,and urine occult blood were also insignificant between the two groups (P>0.05). Conclusion There is no correlation between deficiency-excess syndrome differentiation and disease activity of LN. Most of the LN patients with deficiency syndrome are at active stage,but not at remission stage.

OBJECTIVETo investigate the risk factors for the development of congenital anal atresia in neonates.

METHODSA total of 70 neonates who were admitted to 17 hospitals in Foshan, China from January 2011 to December 2014 were enrolled as case group, and another 70 neonates who were hospitalized during the same period and had no anal atresia or other severe deformities were enrolled as control group. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the development of congenital anal atresia.

RESULTSThe univariate analysis revealed that the age of mothers, presence of oral administration of folic acid, infection during early pregnancy, and polyhydramnios, and sex of neonates showed significant differences between the case and control groups (P<0.05). The multivariate logistic regression analysis revealed that infection during early pregnancy (OR=18.776) and male neonates (OR=9.304) were risk factors for congenital anal atresia, and oral administration of folic acid during early pregnancy was the protective factor (OR=0.086).

CONCLUSIONSInfection during early pregnancy is the risk factor for congenital anal atresia, and male neonates are more likely to develop congenital anal atresia than female neonates. Supplementation of folic acid during early pregnancy can reduce the risk of congenital anal atresia.

The purpose of this study was to quantitatively analyze the relationship between three dimensional arterial spin labeling (3D-ASL) and dynamic susceptibility contrast-enhanced perfusion weighted imaging (DSC-PWI) in ischemic stroke patients. Thirty patients with ischemic stroke were included in this study. All subjects underwent routine magnetic resonance imaging scanning, diffusion weighted imaging (DWI), magnetic resonance angiography (MRA), 3D-ASL and DSC-PWI on a 3.0T MR scanner. Regions of interest (ROIs) were drawn on the cerebral blood flow (CBF) maps (derived from ASL) and multi-parametric DSC perfusion maps, and then, the absolute and relative values of ASL-CBF, DSC-derived CBF, and DSC-derived mean transit time (MTT) were calculated. The relationships between ASL and DSC parameters were analyzed using Pearson's correlation analysis. Receiver operative characteristic (ROC) curves were performed to define the thresholds of relative value of ASL-CBF (rASL) that could best predict DSC-CBF reduction and MTT prolongation. Relative ASL better correlated with CBF and MTT in the anterior circulation with the Pearson correlation coefficients (R) values being 0.611 (P<0.001) and-0.610 (P<0.001) respectively. ROC curves demonstrated that when rASL ≤0.585, the sensitivity, specificity and accuracy for predicting ROIs with rCBF<0.9 were 92.3%, 63.6% and 76.6% respectively. When rASL ≤0.952, the sensitivity, specificity and accuracy for predicting ROIs rMTT>1.0 were 75.7%, 89.2% and 87.8% respectively. ASL-CBF map has better linear correlations with DSC-derived parameters (DSC-CBF and MTT) in anterior circulation in ischemic stroke patients. Additionally, when rASL is lower than 0.585, it could predict DSC-CBF decrease with moderate accuracy. If rASL values range from 0.585 to 0.952, we just speculate the prolonged MTT.
