Objective To investigate the effect of Cordyceps sinensis on renal fibrosis and its possible mechanism.Methods Thirty Sprague-Dawley rats were randomly divided into three groups:Sham operation group (Sham,n =10),5/6 subtotal uephrectomy group (SNx,n =10),and 5/6subtotal nephrectomy treated with Cordyceps sinensis group (CS,n =10).Body weights were assessed and 24-hour urine excretion was collected before and every four weeks after surgery.Rats were sacrificed at 12 weeks after surgery.Blood samples were taken for biochemical study,and kidney tissues were used for HE and Masson stains to assess histological changes.Immunohistochemical staining was used to detect the expression of transforming growth factor β1 (TGF-β1) and its receptors of type Ⅰ (TβR Ⅰ),type Ⅱ (TβR Ⅱ).Immunofluorescence was used to detect E-cadherin and α-SMA.The relative protein level of TGF-β1,TβR Ⅰ,TβR Ⅱ,p-Smad2/3,Smad7,E-cadherin,α-SMA were examined by Western blotting.Results CS group had higher body weights and lower urinary protein,BUN and Scr level compared with SNx group.Glomerulosclerosis index and tubulointerstitial injury score were significantly reduced in CS group compared with those in SNx group (all P ＜ 0.05).The protein expressions of TGF-β1,TβR Ⅰ,TβR Ⅱ,p-Smad2/3 were decreased in CS group compared with those in SNx group (all P ＜ 0.05).CS treatment up-regulated the expression of E-cadherin,Smad7 and down-regulated the expression of α-SMA compared with that in SNx group (all P ＜ 0.05).Conclusion Cordyceps sinensis has inhibitory effect on renal fibrosis in 5/6 subtotal nephrectomy rat model,which might be related with the suppression of TGF-β 1 signal pathway.

Objective To evaluate the applications of magnetic resonance cholangiopancreatography (MRCP) after fat meal in the preoperative evaluation of biliary anatomy of living liver donors.Methods Fifty cases of the preoperative donors for living liver transplantation were included and all had the corresponding intraoperative cholangiography (IOC) information. The MRCP of the donors for living liver transplantation was performed before and after fat meal (two fried eggs). The visualization and diameter of the secondary bile duct were analyzed before and after the fat meal. The results of the biliary branching pattern by MRCP after fat meal were compared with the corresponding IOC results. The accuracy, sensitivity,specificity, positive predictive value and negative predictive value of MRCP after the fat meal in distinguishing normal and any type of variant biliary anatomy were calculated. Results In all cases,82% of the 50 cases in MRCP before the fat meal could meet the diagnosis needs of the preoperative evaluation,and 100% of the 50 cases in MRCP after the fat meal could meet the diagnosis needs. There was significant difference in the demonstration quality and diameter of the secondary bile duct in MRCP before and after the fat meal (P＜0. 05). MRCP showed accurate anatomy of the biliary system, using IOC as the reference standard, in 49(98%) subjects. The sensitivity, specificity, positive predictive value and negative predictive value of MRC in distinguishing normal and any type of variant biliary anatomy were 98%,94. 7%, 100%, 10% and 96. 9%,respectively. Conclusion The MRCP after fat meal can clearly demonstrate the secondary bile duct and perfectly meet the needs of the preoperative evaluation of the living liver transplantation. The MRCP after fat meal and routine MRCP should be considered complementary to one another in order to avoid complications in living liver transplantation donors.

Objective: To investigate the predictors of death after endovascular mechanical thrombectomy (EMT) in patients with acute vertebrobasilar occlusive stroke (VBOS). Methods: Patients with acute VBOS treated with EMT in Wuhan No. 1 Hospital were enrolled retrospectively. The demographic and clinical data were collected. According to whether the patients died at 90 d after procedure, they were divided into survival group and death group. The demographic and clinical data were compared between the two groups. Multivariate logistic regression analysis was used to determine the independent risk factors for death at 90 d after EMT. Results: A total of 47 patients were enrolled. The median age was 62 years, 34 were males (72.3%), the median baseline National Institutes of Health Stroke Scale (NIHSS) score was 16, 42 patients (89.4%) had recanalization (modified Thrombolysis in Cerebral Infarction[mTICI] 2b/3 grade), and 12 (25.5%) died within 90 d after procedure. Univariate analysis showed that the baseline NIHSS score (26 [21-28]vs. 12 [5-23]; Z=-3.165, P=0.002), percentage of neutrophil (81.61% ±11.82% vs. 72.20% ±12.09%; t=-2.137, P=0.033), neutrophil/lymphocyte ratio (10.54±7.17 vs. 4.98±3.57; t=-2.393, P=0.017), and incidence of sICH (25.0% vs. 2.9%; χ²=5.627, P=0.018) in the death group were significantly higher than those in the survival group, while the percentage of lymphocyte (12.00%±9.04% vs. 20.67%±10.39%; t=-2.429, P=0.015) was significantly lower than that of the survival group. Multivariate logistic regression analysis showed that high baseline NIHSS score (odds ratio [OR] 1.243, 95% confidence interval [CI] 1.046-1.318; P=0.038), high neutrophil/lymphocyte ratio (OR 1.278, 95% CI 1.002-1.630; P=0.049) and symptomatic intracranial hemorrhage (OR 5.088, 95% CI 1.065-38.718; P=0.046) were the independent predictors for death. Conclusion High baseline NIHSS score, high neutrophil/lymphocyte ratio and symptomatic intracranial hemorrhage are the independent predictors for death within 90 d after EMT in patients with acute VBOS.

Objective To evaluate the role of dynamic contrast-enhanced magnetic resonance imaging (MRI) in the diagnose of prostatic cancer and benign prostatic hyperplasia (BPH), and to determine the correlation between dynamic MRI findings with angiogenesis.Methods Thirty-two cases of prostatic cancer and 40 cases of BPH underwent dynamic contrast-enhanced MRI.All the patients in this study were diagnosed by histopathology.The results of dynamic contrast-enhanced MRI were evaluated by early-phase enhancement parameters and time-signal intensity curves (SI-T curves), and the curves were classified according to their shapes as type Ⅰ, which had steady enhancement; type Ⅱ, plateau of signal intensity; and type Ⅲ, washout of signal intensity.The pathologic specimens of region of interest (ROI) were obtained, and HE staining, immunohistochemical vascular endothelial growth factor (VEGF), and microvessel density (MVD) measurements were performed.The relationships among dynamic contrast-enhanced MRI features, VEGF, and MVD expression were analyzed.Results In the early-phase enhancement parameters of dynamic contrast-enhanced MRI, onset time,maximum signal intensity, and early-phase enhancement rate differed between prostatic cancer and BPH(P

Objective:To investigate the risk factors of spinal cord injury after FET for ATAAD.Methods:We analyzed perioperative data of 111 patients with ATAAD who underwent FET in the First Affiliated Hospital of Nanjing Medical University from January 2020 to October 2021.Results:Eleven(9.9%)of 111 patients had postoperative spinal cord injury, which showed varying degrees of paralysis or paraplegia. There was no significant difference in age, sex, medical history, cardiopulmonary bypass time, aortic cross-clamping time, circulatory arrest time and FET length between spinal cord injury group and non-spinal cord injury group( P>0.05). Univariate analysis showed that aortic true lumen away from the spinal side( P<0.001) and the number of segmental arteries originating from the true lumen<3 in T9-L3( P<0.001), left subclavian artery involvement( P<0.05) and stent coverage at T8 or beyond( P<0.05) was associated with postoperative spinal cord injury. Multivariate Logistic analysis showed that aortic true lumen away from the spinal side( P<0.001) and the number of segmental arteries originating from the true lumen<3( P<0.001) in T9-L3 and left subclavian artery involvement( P<0.05) were independent risk factors for postoperative spinal cord injury. Conclusion:The pathogenesis of spinal cord injury is complicated. This study suggests that the occurrence of spinal cord injury is significantly related to aortic true lumen away from the spinal side and the number of segmental arteries originating from the true lumen<3 in T9-L3 and left subclavian artery involvement. It is of great clinical significance to identify the high risk factors of postoperative spinal cord injury as early as possible.

Objective:To explore applications of essential balm K-point stimulation on the swallowing rehabilitation in patients with minimally consciousness state, so as to provide reference for patients rehabilitation.Methods:This was a prospective randomized controlled study. A total of 60 minimally consciousness state patients were enrolled by convenience sampling method from Henan Provincial People Hospital from January to December 2021, who were divided into experimental group and control group according to the random number table method, with 30 cases in each group. Both groups received routine rehabilitation therapy, based on this, the control group was given routine K-point stimulation, the experimental group implemented essential balm K-point stimulation. Before and after 4 weeks of intervention, the Kubota water swallowing test and Coma Recovery Scale-revised (CRS-R) was used for assessment.Results:Before intervention, there was no significant difference in Kubota water swallowing test grade and CRS-R scores between two groups (both P>0.05). After 4-week intervention, Kubota water swallowing test Ⅰ-Ⅴ grade were 1, 6, 13, 7 and 3 cases in the control group, while 4, 12, 8, 3 and 3 cases in the experimental group, the difference was statistically significant ( Z = 2.09, P<0.05); the scores of oral motor/verbal function scale were (2.60 ± 1.16) in the experimental group, higher than in the control group (1.90 ± 0.32), the difference was statistically significant ( t = 2.18, P<0.05). Conclusions:Essential balm K-point stimulation can effectively promote swallowing function of patients with minimally consciousness state, and improve patient′s oral motor function.

Objective:To compare the clinical outcomes of endovascular therapy in acute stroke patients with anterior circulation tandem occlusions caused by atherosclerosis or dissection.Methods:A retrospective cohort study. A total of 98 patients with anterior circulation tandem lesions undergoing endovascular therapy in the Wuhan NO.1 Hospital (March 2016 to March 2022) were analyzed. Median age was 64(55,71) years old, and 82.7% (81/98 cases) were males. According to the lesion etiology, the patients were divided into atherosclerosis and dissection groups. The differences in clinical outcomes between the two groups were investigated, including favorable 90-day functional outcome (modified Rankin Scale score of 0-2), successful reperfusion (modified Thrombolysis in Cerebrovascular Infarction score of 2b-3), symptomatic intracranial hemorrhage, stroke-associated pneumonia, 90-day all-cause mortality, and average hospitalization days. Logistic regression analysis was used to adjust for potential confounders affecting functional outcomes in both groups, and to determine odds ratios and 95% confidence intervals.Results:Seventy-one patients were grouped into the atherosclerotic cause and 27 into the dissection cause cohorts. The rate of favorable 90-day functional outcome was 43.7% (31/71 cases) in the atherosclerosis group versus 55.6% (15/27 cases) in the dissection group (adjusted odds ratio=1.339; 95% confidence interval, 0.374-4.798; P=0.654). No significant differences were found in other clinical outcomes between the two groups (all P>0.05). Conclusion:The clinical prognosis of patients with tandem lesions caused by atherosclerotic stenosis or artery dissection was similar after endovascular therapy. Future studies are still needed to verify our results.
