Hispidin is an important styrylpyrone produced by Sanghuangporus sanghuang. To analyze hispidin biosynthesis in S. sanghuang, the transcriptomes of hispidin-producing and non-pro ducing S. sanghuang were determined by Illumina sequencing. Five PKSs were identified using genome annotation. Comparative analysis with the reference transcriptome showed that two PKSs (ShPKS3 and ShPKS4) had low expression levels in four types of media. The gene expression pattern of only ShPKS1 was consistent with the yield variation of hispidin. The combined analyses of gene expression with qPCR and hispidin detection by liquid chro matography-mass spectrometry coupled with ion-trap and time-of-flight technologies (LCMS-IT-TOF) showed that ShPKS1 was involved in hispidin biosynthesis in S. sanghuang.ShPKS1 is a partially reducing PKS gene with extra AMP and ACP domains before the KS domain. The domain architecture of ShPKS1 was AMP-ACP-KS-AT-DH-KR-ACP-ACP. Phylogenetic analysis shows that ShPKS1 and other PKS genes from Hymenochaetaceae form a unique monophyletic clade closely related to the clade containing Agaricales hispidin synthase. Taken together, our data indicate that ShPKS1 is a novel PKS of S. sanghuang involved in hispidin biosynthesis.

Objective:To evaluate the effects of endothelial progenitor cell (EPC)-derived exosomes on neuronal injury induced by oxygen-glucose deprivation and restoration (OGD/R).Methods:HT22 neurons of mice were cultured and divided into 3 groups ( n=30 each) using a random number table method: control group (C group), OGD/R group and OGD/R plus EPC-derived exosome group (OGD/R+ EXO group). Cells in group C were cultured in normal atmosphere.In group OGD/R, the cells were exposed to 94%N 2-1%O 2-5%CO 2 for 6 h in glucose- and serum-free DMEM medium, followed by 24 h restoration of O 2 and glucose in the normal medium.In group OGD/R+ EXO, 20 μg/ml EPC-derived exosomes were added to the culture medium at 24 h before developing the model.EPCs were identified by immunofluorescence staining.Exosomes were identified by Western blot, transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA). Cell viability was measured by CCK-8 assay, the levels of malondialdehyde (MDA) and superoxide dismutase (SOD) were determined by enzyme-linked immunosorbent assay.The neuronal apoptosis was detected by TUNEL staining, and the apoptosis rate was calculated.The expression of Bax, Bcl-2, caspase-3, and cleaved caspase-3 was determined by Western blot, and cleaved caspase-3/caspase-3 ratio was calculated. Results:The cultured cells were EPCs, and EPC-derived exosomes were successfully extracted.Compared with group C, the cell viability was significantly decreased, the content of MDA was increased, the activity of SOD was decreased, the apoptosis rate was increased, the expression of Bax was up-regulated, the expression of Bcl-2 was down-regulated, and the ratio of cleaved-caspase-3/caspase-3 was increased in group OGD/R and group OGD/R+ EXO ( P<0.05). Compared with group OGD/R, the cell viability was significantly increased, the content of MDA was decreased, the activity of SOD was increased, the apoptosis rate was decreased, the expression of Bax was down-regulated, the expression of Bcl-2 was up-regulated, and the ratio of cleaved-caspase-3/caspase-3 was decreased in group OGD/R+ EXO ( P<0.05). Conclusions:EPC-derived exosomes can reduce OGD/R-induced neuronal injury, which is related to inhibition of oxidative stress and neuronal apoptosis.

Iliac vein stenosis (IVS), known as iliac vein compression syndrome, refers to a series of diseases caused by iliac vein compression or intraluminal adhesions leading to lower extremity vein or pelvic vein drainage disturbance and other clinical manifestations which is quite common in vascular surgery. The vast majority of patients with symptoms of chronic venous insufficiency (CVI) have IVS. In clinical work, IVS does not typically appear as a single symptom, while often combining with other lesions, such as varicose veins of the lower extremities, skin pigmentation, ulcer formation. Studies on its aetiology and epidemiology have found a mean age of onset of 40 years, the age of onset in females is lower than that in males, and the average of stress in females is significantly higher than that in males. Typical IVS occurs mainly in the left lower extremity in young women of reproductive age, but exceptions remain. In summary, the importance of the diagnosis of IVS in clinical practical work can be seen. CVI is a general term for all diseases that affect the morphology and function of the venous system. Compared with chronic venous disease (CVD), CVI include venous system abnormalities without symptoms or signs. Thus, it more accurately describes the diagnosis and treatment of IVS that requires clinical guidance, so its concept is quoted. With the development and advancement of medical imaging, more and more techniques provide help in the diagnosis and treatment of IVS. Therefore, professionals in various specialties have made relevant studies about the benefits and drawbacks of imaging techniques for diagnosis, treatment modalities, and prognostic management of this disease, in order to improve the diagnostic efficacy. Consequently, this review is focused on the current situation of the diagnosis and treatment of IVS under multi-modal imaging, hoping to provide choices of medical imaging technologies for the different states, and to find a better and personalized plan for patients.

Objective:To investigate the efficacy of different treatment modes for locoregional recurrence after nephrectomy in patients with renal cell carcinoma.Methods:A total of 106 patients with locoregional recurrence after nephrectomy without distant metastasis (77 males and 29 females) admitted to Sun Yat-sen University Cancer Center from October 2001 to July 2020 were retrospectively analyzed. The median age was 51 (40, 60) years old. Radical nephrectomy was performed in 90 patients with primary tumor and partial nephrectomy was performed in 16 patients. Pathological diagnosis showed that 54 cases were clear cell carcinoma and 52 cases were non-clear cell carcinoma. 53 cases were in stage T 1-2 and 53 cases in stage T 3-4. The median diameter of recurrent lesions was 3.2 (2.0, 6.3) cm, and the median number was 2 (1, 4). The recurrence sites were divided into renal fossa recurrence (33 cases), renal fossa±retroperitoneal lymph node recurrence (38 cases), and intra-abdominal spread (35 cases). The median duration from primary surgery to local recurrence was 14.8 (7.3, 35.8) months. Two treatment groups were identified as systemic therapy alone (Group A) and local therapy with or without systemic therapy (Group B). The Kaplan-Meier method was used to compare the progression free survival (PFS) and overall survival (OS) between Group A and Group B. The Cox model was used to perform univariate and multivariate analysis. Results:Of all the 106 patients, 33 patients were in Group A and 73 patients were in Group B. In Group A, 29 patients (87.9%) received targeted therapy, and 4 patients (12.1%) received targeted therapy combined with immunotherapy. In Group B, 34 patients (46.6%) received surgery or ablation and 39 patients (53.4%) received SBRT, of which 62 patients (84.9%) received concurrent systemic therapy. Among them, 58 patients (93.5%) received targeted therapy, and 4 patients (6.5%) received targeted therapy combined with immunotherapy. The median follow-up period was 29.0 (15.4, 45.9) months, 64 patients progressed on tumor including 28 patients died. The median PFS and OS were 15.6 (7.1, 35.2) months and 66.9 (37.8, not reached) months. The median PFS of Group A and Group B were 7.6(5.0, 17.2)months and 22.2(9.6, 63.9)months respectively ( P=0.001), median OS of Group A and Group B were 45.7 (23.4, 62.8)months and 71.0(50.6, not reached)months respectively, and the 2-year OS were 70.6% and 85.5% in Group A and Group B respectively ( P=0.023). The univariate analysis showed local therapy with or without systemic therapy was significantly reduced 56% risk of tumor progression ( HR=0.44, P=0.003) and reduced 60% risk of death ( HR=0.40, P=0.028). The multivariate analysis showed that the OS was associated with ECOG score( HR=10.20, 95% CI 4.13-25.30, P<0.001)and local therapy( HR=0.23, 95% CI 0.09-0.58, P=0.002). Conclusion:Compared with systemic therapy alone, local therapy with or without systemic therapy can effectively improve the PFS and OS of patients with locoregional recurrence after nephrectomy.

Objective To investigate the expressions of Krüppel like factor 5 (KLF5) and tumor necrosis factor receptor superfamily member 11a (TNFRSF11a) in cervical cancer tissues and their effect on proliferation,migration,and invasion of HeLa cells. Methods Microarray technology was used to detect the mRNA expression of gene in cytocine stimulusin cervical tissues,and the result was verified by real-time fluorescence quantitative polymerase chain reaction. The expressions of KLF5 and TNFRSF11a in cervical tissues were detected by double immunofluorescence staining. HeLa cells were transfected with specific small interfering RNA to knock down the endogenous TNFRSF11a and KLF5 and were infected with adenovirus containing KLF5 to over-express KLF5,respectively. Protein level was detected by Western blot. The regulatory effect of KLF5 on candidate target gene (TNFRSF11a) was determined by dual-luciferase reporter assay. The activity of the cell proliferation,migration,and invasion was detected by using cell counting kit-8 assay and Transwell assay. Results The results of microarray technology showed that the expressions of KLF5 and TNFRSF11a were significantly higher in cervical squamous cell carcinoma tissues compared with normal cervical tissues (P=0.002,P=0.045),and real-time fluorescence quantitative polymerase chain reaction showed that the mRNA expressions of KLF5 and TNFRSF11a were significantly higher in cervical intraepithelial neoplasia (CIN) Ⅰ,CINⅡ-Ⅲ and cervical squamous cell carcinoma tissues compared with normal cervical tissues (KLF5:F=32.79,P=0.018,P=0.014,and P=0.011;TNFRSF11a:F=36.72,P=0.013,P=0.010,and P=0.009) and double immunofluorescence staining showed that the protein expressions of KLF5 and TNFRSF11a were significantly higher in CIN Ⅰ,CIN Ⅱ-Ⅲ and cervical squamous cell carcinoma tissues compared with normal cervical tissues (KLF5:F=42.38,P=0.014,P=0.008,and P=0.002;TNFRSF11a:F=35.42,P=0.021,P=0.012,and P=0.004) and increased with the carcinogenesis. The experiment in vitro confirmed that KLF5 promotes proliferation,migration,and invasion of HeLa by up-regulating TNFRSF11a expression. Clinical analysis showed that the expression of TNFRSF11a mRNA was positively correlated with tumor pathological grading,clinical stage,depth of invasion,and lymph node metastasis (all P<0.05). Conclusion KLF5 and TNFRSF11a are related to cervical cancer. KLF5 promote the proliferation,migration,and invasion of cervical cancer cells partly by upregulating the transcription of TNFRSF11a.
