Objective: To assess the diagnostic rate, safety and clinical application of percutaneous renal masses biopsy for advanced renal cell carcinoma patients.Methods: In this retrospective study, we collected the data of renal masses from the patients who underwent renal masses biopsy under ultrasound from April 2001 to December 2014 in Peking University First Hospital.A total of 75 patients who were undiagnosed or diagnosed with advanced renal cell carcinoma by the imageological method were enrolled in this study.The patient and lesion characteristics such as tumor size, pathology of tumor, histologic subtype, pathological grade, biopsied location and biopsied cores were recorded and analyzed.Results: Among all the 75 patients, biopsy was diagnostic in 64 cases (85.3%) and non-diagnostic in 11 cases (14.7%).Of the 64 diagnostic biopsies, 60 were malignant, including 37 (61.7%) renal cell carcinoma (RCC), 13 (21.7%) urothelial carcinoma and 10 (16.7%) other malignant masses.Of all the RCC subjects, 24 suffered from clear cell RCC, 5 papillary RCC, 3 collecting duct carcinomas, 1 unclassified RCC and 4 unknown subtypes.The 11 non-diagnostic biopsied samplings included inflammatory, blood and extrarenal tissue and normal renal tissue.The proportion of collecting duct carcinoma in RCC was 10.8% and the proportion of squamous carcinoma in urothelial carcinoma was 23.1%, which were both higher than the previous research findings.For the male and female groups, non-diagnostic yields were 6.5% and 30.4%, respectively (P=0.022).Of all the 75 patients, 13 renal cell carcinoma patients underwent the surgical treatment and got the results of postoperative pathology.Comparing preoperative biopsy pathological diagnosis with postoperative pathological diagnosis, we found the diagnostic correct rates for benign and malignant lesions, pathological subtype and pathological grade were 100%, 81.8% and 60%, respectively.Mild macroscopic hematuria occurred in 1 case after RMB and there were no serious complications in all the cases.Conclusion: Percutaneous renal masses biopsy under ultrasound with a high diagnostic rate which can define the histologic subtype of renal cell carcinoma.With targeted therapy, more and more patients whose evaluation suggests local advanced disease or metastatic tumors adopt renal tumor biopsy to define the histologic subtype, which could avoid unnecessary surgical treatment.

Cytomegalovirus hepatitis is a liver disease caused by human cytomegalovirus infection and is one of the most common liver diseases in children and immunocompromised individuals. This disease has no specific clinical manifestations and is easily confused with other types of viral hepatitis, which may lead to delayed treatment or mistreatment. Therefore, the early diagnosis of cytomegalovirus hepatitis is of vital importance, and patients should be given timely and effective treatment with appropriately selected antiviral drugs and course of treatment. This article reviews the recent research advances in the etiology, epidemiology, pathogenesis, clinical manifestations, diagnosis, treatment, and prevention of cytomegalovirus hepatitis.

Objective:To investigate the conversion of low-energy CBCT images into high-energy CBCT images in clinical radiotherapy based on the deep learning method of U-Net network, in order to provide dual-energy CBCT images and reduce radiation dose.Methods:The CBCT image data of CIRS electron density phantom and CIRS head phantom at 80 and 140 kV were collected by the on-board CBCT in radiotherapy equipment. The dataset was divided into training set and test set according to 10∶1. The U-Net network was used to predict CBCT images at high energy (140 kV) from low-energy (80 kV) CBCT images. Four parameters, including mean absolute error (MAE), structural similarity index (SSIM), signal-to-noise ratio (SNR) and peak signal-to-noise ratio (PSNR) were used to quantitatively evaluate predicted high-energy CBCT images.Results:The overall structural difference between the predicted high-energy image and the real high-energy image was smaller (SSIM: 0.993 ±0.003). The noise of predicted high-energy image was lower (SNR: 15.33±4.06), but there was a loss of inter-tissue resolution. Predicted high-energy images had slightly lower average CT values than real high-energy images, with less difference in low-density tissues (<10 HU, P > 0.05) and greater differences in high-density tissues (<21 HU, t = -7.92, P < 0.05). Conclusions:High-energy CBCT images with high structural similarity can be obtained from energy CBCT images by using deep learning method. The predicted high energy CBCT images have the potential to be applied to clinical dual-energy CBCT imaging technology in radiotherapy.

Objective:To investigate the role of Pink1/Parkin-induced mitophagy in acute lung injury of exertional heat stroke rats.Methods:Sixty SD rats were randomly divided into four groups, including normal group (CON group), normal Parkin overexpression group (CON+Parkin group), heat stroke group (EHS group) and heat stroke Parkin overexpression group (EHS+Parkin group), with fifteen rats in each group. The rat model of exertional heat stroke was established and the survival curve was drawn. Pulmonary coefficient and pulmonary capillary permeability were detected. HE staining was used to observe the pathological changes of lung tissue. ELISA was used to detect the contents of IL-6, IL-1β, TNF-α and ROS in lung tissue; immunohistochemistry was used to observe apoptosis in lung tissue; Western blot was used to determine the expression of Pink1, Parkin, P62 and LC3 in rat lung tissue, and the LC3II/LC3I ratio was calculated. Single factor multi-level group comparison was performed by single factor analysis of variance, SNK-q method was used to further pairwise comparison between groups.Results:Compared with the normal group, the survival rate of EHS group was decreased ( P<0.001), lung coefficient and pulmonary vascular permeability were increased [(4.39±0.42), (33.38±8.29) μg/g, P<0.05)], lung tissue was exudative and solid, the levels of inflammatory factors IL-6, IL-1β, TNF-α and ROS were significantly increased[(34.31±5.34) pg/mL, (34.03±4.78) pg/mL, (91.64±8.16) pg/mL, (259.01±89.17) U/mg, P<0.05)], and apoptosis was increased. Western and immunohistochemistry results showed that the expressions of Pink1 and Parkin were decreased, co-location of Pink1and Parkin was attenuated, LC3II/LC3I were decreased, and P62 expression was increased. Compared with the EHS group, the survival rate of EHS+Parkin group was significantly increased ( P<0.05), lung coefficient and pulmonary vascular permeability were decreased [(3.83±0.62), (22.49±7.90) μg/g, P<0.05)], exudation and consolidation and other pathological changes were significantly reduced, and the levels of the above inflammatory factors and ROS were significantly decreased [(14.09±3.24) pg/mL, (26.94±2.11) pg/mL、(63.35±11.62) pg/mL, (161.13±26.31) U/mg, P<0.05]. Lung tissue apoptosis was reduced. The co-location of Pink1and Parkin、Parkin expression and LC3II/LC3I ratio were increased ( P<0.05), P62 expression was decreased( P<0.05), while Pink1 expression was not significant different (q=0.75). There was no difference between normal group and normal Parkin overexpression group (q=0.95). Conclusion:Activation of Pink1/Parkin-induced mitophagy can alleviate the acute lung injury in exertional heat stroke rats.

Esophageal cancer is one of the most lethal cancers worldwide because of its rapid progression and poor prognosis. Esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC) are two major subtypes of esophageal cancer. ESCC predominantly affects African and Asian populations, which is closely related to chronic smoking and alcohol consumption. EAC typically arises in Barrett's esophagus with a predilection for Western countries. While surgical operation and chemoradiotherapy have been applied to combat this deadly cancer, molecularly targeted therapy is still at the early stages. With the development of large-scale next-generation sequencing, various genomic alterations in ESCC and EAC have been revealed and their potential roles in the initiation and progression of esophageal cancer have been studied. Potential therapeutic targets have been identified and novel approaches have been developed to combat esophageal cancer. In this review, we comprehensively analyze the genomic alterations in EAC and ESCC and summarize the potential role of the genetic alterations in the development of esophageal cancer. Progresses in the therapeutics based on the different tissue types and molecular signatures have also been reviewed and discussed.
