Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

ObjectiveTo establish a mouse model of basilar artery dolichoectasia （BAD） and explore the mechanism of modified Tongqiao Huoxuetang （JTQHX） in regulating BAD via phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） pathway. MethodSixty C57/BL6 female mice were randomized into sham operation （injected with 10 U·mL^-1 inactivate elastase）， model， atorvastatin calcium tablets （2.6 mg·kg·d^-1）， and low- and high-dose （crude drug 3.4， 17 g·kg^-1·d^-1， respectively） JTQHX groups. The mouse model of BAD was established by injection with 10 U·mL^-1 elastase. After 14 days of modeling， the sham operation group and model group were administrated with equal volumes of pure water by gavage， and other groups with corresponding drugs for 2 months. The levels of interleukin-6 （IL-6） and calpain （LpA） in the serum were measured by enzyme-linked immunosorbent assay （ELISA）. Verhoeff 's Van Gieson （EVG） staining was employed to observe the pathological changes of blood vessels. Terminal-deoxynucleotidyl transferase mediated nick end labeling （TUNEL） was employed to examine the apoptosis rate of vascular smooth muscle cells （VSMCs）. Image Pro Plus was used to observe and calculate the curvature index， elongation length， percentage increase in vessel diameter， and curvature angle of the basilar artery vessels in mice. Western blot was employed to determine the expression levels of PI3K and Akt in the vascular tissue. ResultCompared with the sham operation group， the model group showed lowered IL-6 level （P<0.01）， no significant change in LpA level， increased apoptosis of VSMCs （P<0.01）， and increased curvature index， elongation length， percentage increase in vessel diameter， and curvature angle （P<0.01）. Furthermore， the modeling up-regulated the protein levels of PI3K and Akt in blood vessels （P<0.01） and aggravated the destruction of the inner elastic layer， atrophy of the muscular layer， and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. Compared with the model group， 2 months of treatment with JTQHX elevated the IL-6 level （P<0.01）， reduced the apoptosis of VSMCs （P<0.01）， decreased the curvature index， elongation length， percentage increase in vessel diameter， and curvature angle （P<0.05， P<0.01）， and down-regulated the protein levels of PI3K and Akt in blood vessels （P<0.01）. In addition， the treatment alleviated the destruction of the inner elastic layer， atrophy of the muscular layer， and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. ConclusionJTQHX inhibits the elongation， expansion， and curvature of basilar artery vessels and alleviates the pathological changes by reducing the apoptosis of VSMCs and down-regulating the expression of PI3K/Akt pathway.

Primary hyperoxaluria type 3 (PH3) is a rare monogenic nephrolithiasis caused by HOGA1 gene mutations. With the advancement of technology of genetic testing, the mutation site of PH3 patients can be clearly located, and the characteristics of genotype, phenotype, genotype-phenotype correlations are also gradually recognized. With the development of gene therapy, novel gene editing techniques and RNA interference treatments offer hope for the future of PH3 treatment. In this paper, the characteristics of genotype and phenotype, genotype-phenotype correlations of PH3 will be summarized and its future treatment will be prospected.

IgG4-related disease (IgG4-RD) involving the ureter manifested as a ureteral tumor is rare. This paper reports a case of a female patient who was found with a mass at the left ureteropelvic junction for one week during physical examination. Urinary ultrasound and MRI showed a 3 cm mass at the left ureteropelvic junction with hydronephrosis, and the serum level of IgG4 was elevated. B-ultrasonic guided biopsy of the mass was performed. Histopathological findings showed lymphoplasmic infiltration and the ratio of IgG4/IgG positive cells>0.5. We finally diagnosed IgG4-RD and started using glucocorticoid for her treatment. One month later, CT-scan revealed that the tumor became smaller and the serum IgG4 decreased to the normal range.

Ectopic prostate is rare.This paper reports a case of a male patient who was found a mass in the pelvis for 20 days during physical examination.Urinary ultrasound, CT scan and MRI showed a pelvic mass that was about 4 cm×5 cm in size.Serum total prostate specific antigen (tPSA) was 6.09 ng/ml, and free PSA (fPSA) was 1.97 ng/ml. B-ultrasonic guided biopsy of the prostate and the mass was performed. Pathological findings suggest benign prostatic hyperplasia, weakly positive P504S and positive 34βE12. Pelvic mass is the prostate tissue with negative P504S and positive 34βE12. Finally, the ectopic prostate was diagnosed. Although it is rare, ectopic prostate should also be considered as a differential diagnosis of the pelvic tumor.

Renal abscess caused by fish bone ingestion is extremely rare and has not been reported in the literature. A male patient presented with a 1-week history of flank pain and a 2-day history of fever. Urinary ultrasound and CT scan showed an irregular hypodense lesion in the left kidney and blurred thickening of the descending colon wall. Three-dimensional CT reconstruction images revealed a needle-like foreign body, which perforated from the descending colonic lumen to the left kidney. The patient had accidentally eaten fish bone one week prior. On the basis of clinical data, the diagnosis of renal abscess caused by foreign body was suspected. Accordingly, laparotomy was performed, the abscess was drained, and the colon was repaired. The foreign body was confirmed to be fish bone. The postoperative condition of the patient was uneventful, and the patient remained well in the 3 months' follow-up without any further complaints.

OBJECTIVE To study the effects of ginsenoside Rb 1（G-Rb1）on epithelial-mesenchymal transition （EMT）of renal tubular epithelial cells and its potential mechanism. METHODS The growth factor β1（TGF-β1）10 ng/mL was used to induce EMT of human renal tubular epithelial cells HK- 2. The morphological changes of HK- 2 cells were observed after treated with 10， 20，30 μmol/L G-Rb1 for 48 h. The transcriptional activities of biovector SBE in human embryonic kidney cell HEK 293 were determined after 24 h treatment with 1.0，2.5，5.0，10，20，30 μmol/L G-Rb1. Effects of above concentration of G-Rb 1 on the viability of HK- 2 cells were determined after 24 h of treatment. mRNA expressions of α-smooth muscle actin （α-SMA），collagen Ⅰ （COL-Ⅰ）and fibronectin （FN）in HK- 2 cells were detected after treated with 10，20，30 μmol/L G-Rb1 for 24 h. The expressions of α-SMA，Smad3，p-Smad3，COL-Ⅰ，FN and E-cadherin were detected after treated with 10，20，30 μmol/L G-Rb1 for 24 h. RESULTS G-Rb1 of 10-30 μmol/L significantly inhibited TGF-β1-induced EMT in HK- 2 cells and the increase of transcriptional activities of biovector SBE induced by TGF-β1（P＜0.05），but had no effects on relative activities of HK- 2 cells（P＞0.05）. The protein and mRNA expressions of α-SMA，COL-Ⅰ and FN ， the protein expressions of Smad 3 and p-Smad 3 were significantly up-regulated induced by TGF-β1（P＜0.05），while the protein expression of E-cadherin was significantly down- regulated（P＜0.05）；G-Rb1 could effectively reverse aboveprotein or mRNA expressions. CONCLUSIONS G-Rb1 can protect renal tubular epithelial cells from EMT induced byxiezhishen TGF-β1 to a certain extent ，which may be related to inhibiting the activation of TGF-β1/Smad3 signaling pathway.
