【Objective】 Based on the high-throughput sequencing data of the whole genome， genomics and bioinformatics analyses were made to analyze the gene expression changes in the epithelial cells of the lung tissue from patients with coronavirus disease 2019 （COVID-19）， and explore the effects of the new coronavirus SARS-CoV-2 on human lungs. This study can provide a theoretical basis for the exploration of SARS-CoV-2 on the pathogenesis of lung tissue. 【Methods】 The public data set GSE160435 was retrieved. The data were analyzed by Network analyst， Cytoscape 3.7.2， String 11.0， and other software. The differentially expressed genes were screened， gene function （Gene Ontology， GO） and signal pathway KEGG （Kyoto Encyclopedia of Genes and Genomes） enrichment analysis were carried out. We established the Protein-protein Interactions Network （PPI）， PPI of lung tissue-specific DEGs， DEG microRNA regulatory network， Transcription Factor （TF）-DEG regulatory network， and environmental chemicals DEGs regulatory network. 【Results】 We found 324 DEGs in the lung epithelial cells of patients with COVID-19， of which 112 （34.57%） were upregulated and 212 （65.43%） were downregulated. Enrichment analysis showed that DEGs were mainly involved in biological processes such as virus-related defense response， mainly involved in protein digestion and absorption， anti-human papillomavirus infection and other signaling pathways. Specific PPI network closely related to DEGs and lung tissue showed that PDGFRB and KIT were core proteins； hsa-mir-340 had targeted interaction with DEGs. It indicated that HOXB4， ISG15 and other related genes were regulated by transcription factors； DEGs interacted with environmental chemicals such as nickel and estradiol. 【Conclusion】 The gene expression pattern of lung epithelial cells in lung tissue of COVID-19 patients has changed significantly. Proteins or genes such as PDGFRB， MMP9 and KIT may play a vital role in the defense immunity of lung tissue. Micro-RNA， TF， signaling pathway molecules， environmental chemicals， and lung tissue-specific genes also play a role in the above-mentioned process. This study provides new ideas for exploring the pathogenic mechanism of SARS-CoV-2 on lung tissue and formulating clinical prevention， diagnosis and treatment measures.

Objective To evaluate the effect of the different Child-Pugh classification on the recurrence and survival of hepatocellular carcinoma (HCC) recipients after liver transplantation. Methods Clinical data of 125 HCC recipients undergoing liver transplantation were retrospectively analyzed. The 3-year disease-free survival (DFS) and overall survival (OS) rates were calculated by Kaplan-Meier survival curve. The independent risk factors probably affecting the recurrence and survival of HCC recipients after liver transplantation were identified by using Cox's proportional hazards regression model. Results The median follow-up time was 25.6 months. The 3-year DFS and OS rates were 68.4% and 65.7% for all patients. The 3-year DFS and OS rates in 113 patients with Child-Pugh class A/B HCC were 68.6% and 66.2%, whereas 66.7% and 65.6% for 12 patients with Child-Pugh class C HCC with no statistical significance (all P>0.05). Cox's proportional hazards regression model demonstrated that vascular invasion (P=0.001)and the number of tumors>3 (P=0.025) were the independent risk factors for the postoperative recurrence of HCC in recipients undergoing liver transplantation. Alpha fetoprotein (AFP)>400μg/L (P=0.035), vascular invasion (P=0.031) and number of tumors>3 (P=0.008) were the independent risk factors affecting the survival of HCC patients. Conclusions The postoperative prognosis does not significantly differ between Child-Pugh class C and A/B HCC patients after liver transplantation. AFP, vascular invasion and number of tumors are the risk factors affecting the clinical prognosis of HCC patients after liver transplantation. Liver transplantation is an efficacious treatment for HCC patients with Child-Pugh class C.

Objective To explore the efficacy of the single versus combination drug therapies for benign prostatic hyperplasia(BPH) combined with overactive bladder(OAB).Methods A total of 471 outpatients with BPH and OAB meeting the inclusion/exclusion criteria were enrolled in this prospective cohort study from March 2012 to October 2015.Patients were divided into two groups:(1) the single alpha-blocker treatment group (prostate volume ＜ 30 ml),and (2) the 5 alpha reductase inhibitors(5-ARIs) plus alpha-blocker combination treatment group(prostate volume ≥ 30 ml).The 318 patients were treated with alpha blockers for 4 weeks,and then received a continuing alpha-blocker treatment for 8 weeks if IPSS score changes were less than 30％ (i.e.single alpha-blocker treatment group).And 153 patients were treated with 5-ARIs for 12 weeks,then received 5-ARIs plus alpha-blocker combination treatment for another 4 weeks(a total of 16 weeks)if IPSS score changes were less than 30 ％ (i.e.combination treatment group).The improvements of post-voiding residual(PVR),PV,maximum urinary flow rate(Qmax),international prostate symptom score(IPSS),overactive bladder symptom score (OABSS),quality of life (QOL),urine storage period symptom score (USPSS) and voiding symptom score(VSS)were compared between the two groups.Results The values of IPSS,OABSS,QOL,USPSS and VSS index in the two groups were improved after treatment as compared with pre-treatment(all P≤0.05).Patients in combination treatment group had little improvement in PVR and Qmax after treatment.The OAB symptom remission rates of BPH patients with OAB in single alpha-blocker treatment group were 70.5％ (206/292)and 78.6％ (165/210)after 4 and 12 weeks of treatment respectively.The OAB symptoms remission rates of BPH patients with OAB in combination treatment group were 54.5 ％ (64/122) and 67.1％ (53/79) after 12 and 16 weeks of treatment respectively.Conclusions Both single alpha-blocker treatment and alpha-blocker plus 5ARIs combination treatment,which identification was based on prostate volume,have good effects on BPH patients with OAB.The single alpha-blocker treatment can improve PVR and Qmax,and the alpha-blockers plus 5ARIs combination treatment can improve the prostate volume in BPH patients with OAB.

Objective To evaluate the clinical efficacy of application of hepatitis B surface antigen (HBsAg)-positive donor liver in adult liver transplantation. Methods Clinical efficacy of 28 recipients with liver diseases induced by virus B hepatitis (hepatitis B) undergoing liver transplantation using HBsAg-positive donor liver from July 2012 to October 2015 was retrospectively analyzed. Clinical prognosis and postoperative complications of the recipients were summarized. The changing features of serum levels of HBsAg and hepatitis B virus (HBV) DNA was investigated. Results After liver transplantation, 28 recipients were orally administered with entecavir to prevent the recurrence of hepatitis B. During perioperative period, 2 recipients died from sepsis and acute heart failure. During postoperative follow-up, 2 cases died from the recurrence of hepatocellular carcinoma (liver cancer). The remaining 24 patients were followed up for 12-26 months. Throughout the follow-up, 24 recipients were positive for serum HBsAg. After treatment, the titre of HBV DNA was significantly declined to <1×102 copies/mL at postoperative 12 months. No graft dysfunction induced by hepatitis B recurrence occurred in 24 recipients alive. Conclusions As a marginal donor liver, HBsAg-positive liver graft is safe for liver transplantation in the recipients with hepatitis B-related liver diseases. Postoperatively, anti-HBV treatment should be strengthened and intimate follow-up should be delivered.
