Objective To survey the incidence of hepatocellular carcinoma (HCC) in patients with HBV-related cirrhosis receiving nucleos(t)ide analogues treatment and to assess its risk factors.Methods A total of 141 patients with HBV-related liver cirrhosis receiving nucleos(t) ide therapy from April 2008 to June 2011 were enrolled.The clinical data including virological and biochemical tests were retrospectively analyzed.Univariate and multivariate Cox proportional hazards regression model was used to identify the risk factors of HCC occurrence.Results Patients were followed up for 6.4 to 87.6 months with a median followup time of 32.5 months.During the follow-up period,15 out of 141 patients developed HCC with an average annual incidence rate of 3.8％.HCC incidence was higher in HBeAg positive cirrhosis and in those with family history of liver cancer ( RR =4.524 and 3.858,P ＜ 0.05 ).Conclusions Patients with HBV-related cirrhosis have a high incidence rate of HCC even they recieve nucleos (t) ide analogues treatment.HBeAg positive cirrhosis and family history of liver cancer are independent risk factors for HCC.

Objective To study liver function, hepatic energy metabolism, regeneration and apoptosis in obstructive jaundiced or normal liver after 70% partial hepatectomy (PH) with hepatic artery resection (HAR) in rats. Methods In this study, 133 male SD rats were enrolled, 6 rats were in sham operation group, 20 rats underwent choledochoduodenostomy after 70% PH and 20 rats did 70%- PH, choledochoduodenostomy plus HAR. The remaining 87 rats 5 days after common bile duct ligation (CBDL) were randomized into two groups: 70% PH with choledochoduodenostomy, and 70% PH with choledochoduodenustomy plus HAR. Serum TB, ALT, ALB and ALP; tissue of hepatic HGF, bcl-2 mRNA and protein expression; ATP, ADP and AMP in hepatic tissues; hepatocyte proliferation/ apoptosis index were observed postoperatively (24 h, 72 h and 7 d). MortaLity was calculated. Results Rats without obstructive jaundice could tolerate 70% PH plus HAR with good liver regeneration. Compared with other groups, the serum liver function index; ATP content and EC value; HGF,bcl-2 mRNA content of liver tissue and the hepatocyte proliferation/apoptosis index in 70% PH with HAR group significantly aggravated and the mortality signiticanfly increased in obstructive jaundice rats ( P < 0. 05). Conclusions (1) The liver regeneration and apoptosis were not significantly influenced in normal mrs undergoing 70% PH and 70% PH with HAR, moreover hepatoeyte energy metabolism and liver function recovered rapidly in both groups. (2) With the existence of severe bilirubinemia, 70% PH with HAR caused an increased mortality suggesting a rationale for a preoperative bilirubin reducing procedures before a major surgery in malignant obstructive jaundice.

Objective:To determine the risk profile of venous thromboembolism (VTE) and evaluate VTE prophylaxis implementation of the hospitalized cancer patients in the DissolVE 2 study.Methods:The data of hospitalized cancer patients in the DissolVE 2 study were analyzed. The risk distribution of VTE, preventive measures and in-hospital VTE events of hospitalized patients with tumors were described by percentage and 95% confident interval (CI).Results:A total of 1 535 cancer patients were included. According to the Padua score, 826 (53.8%) patients were at low risk of VTE, while 709 (46.2%) patients were at high VTE risk. VTE events occurred in 4 low-risk patients (0.5%; 95% CI: 0.1%, 1.2%) and 5 high-risk patients (0.7%; 95% CI: 0.2%, 1.6%). The overall incidence was 0.6% (9/1 535, 95% CI: 0.3%, 1.1%). Among patients with high VTE risk, 666 (93.9%) did not receive any VTE prophylaxis, and only 11 (1.6%) patients received appropriate VTE prophylaxis. Among patients who received VTE prevention, no VTE event was observed. Conclusions:Nearly half of the hospitalized cancer patients are at high risk of VTE, but most of them don′t receive VTE prophylaxis. The results reflect the insufficient management of VTE risk for hospitalized cancer patients in China, and improvement of awareness and practice of VTE prophylaxis is urgently needed.

Objective:To explore the safety and therapeutic effect of programmed death 1 (PD-1) antibody combined with chemotherapy as a neoadjuvant therapy for patients with stage Ⅱ to Ⅲ non-small cell lung cancer (NSCLC).Methods:Thirteen patients, who had been diagnosed as stage Ⅱ-Ⅲ NSCLC and received PD-1 inhibitor plus chemotherapy as a neoadjuvant treatment in National Cancer Center/Cancer Hospital were recruited. The patients received consecutive neoadjuvant chemotherapy for 21 days as a cycle and the therapeutic efficacy was evaluated after two cycles.Results:At the last time of follow-up on December 2, 2019, the objective response rate (ORR) and disease control rate (DCR) of these patients were 61.5% (95% CI 30.9%-92.1%) and 100%, respectively. The downregulation rate of disease stage was 61.5% (8/13). The resectable rate was 38.5% (5/13), among them, the major pathologic response (MPR) was 60.0% (3/5) and the complete pathologic response (CPR) was 20.0% (1/5). The neoadjuvant chemotherapy displayed a low incidence of adverse reaction. The main grade 3 to 4 toxicities were neutropenia (38.5%) and leukopenia (23.1%). There was no significant immune-related toxicity. The safety and tolerability of perioperative period of patients underwent resection were promising. Conclusions:Immunotherapy combined with chemotherapy as a neoadjuvant treatment is an effective, low-toxicity treatment manner, which has perioperative safety and high rate of MPR for patients with resectable NSCLC. It is a promising treatment option for patients with stage Ⅱ to Ⅲ NSCLC.

Testicular radiation injury is a structural and functional abnormality of the testes caused directly or indirectly by radiation, which disrupts spermatogenesis and compromises male fertility. The development of effective preventive and therapeutic interventions is essential because of the high prevalence of this condition in clinical settings and its profound effect on patients′ reproductive health and overall well-being. The concept of "the struggle between vital qi and pathogen" is first seen in the Treatise on Cold Pathogenic Diseases. It denotes the dynamic struggle between vital and pathogenic qi. The occurrence, development, and sequelae of all diseases reflect this ongoing conflict. In this context, this study defines the "vital qi" of the testis as its capacity to generate and preserve the essence of reproduction and to resist damage. The pathogenic qi associated with testicular radiation injury is categorized into two types: ionizing poison and retaining evil. The pathogenesis of testicular radiation damage is delineated into three stages by integrating the characteristics of vital and pathogenic qi: the injury, adhesion, and recovery phases. Based on the theoretical framework advanced by this study, the therapeutic approach for testicular radiation injury should adhere to the fundamental principle of strengthening vital qi and eliminating pathogenic factors. Although the primary focus of treatment should be on strengthening vital qi, it should also be complemented by strategies to eliminate pathogenic influences. This paper aims to provide a novel perspective and strategic approach to the traditional Chinese medicine diagnosis, prevention, and treatment of testicular radiation injury. By elucidating the process of testicular radiation injury and its corresponding treatment principles, it seeks to offer valuable insights for clinical practice.

Mucin16 (MUC16), also known as carbohydrate antigen 125 (CA125), is a glycoprotein antigen that can be recognized by the monoclonal antibody OC125 detected from epithelial ovarian carcinoma antigen by Bast et al in 1981. CA125 is not present in normal ovarian tissue but is usually elevated in the serum of epithelial ovarian carcinoma patients. CA125 is the most commonly used serologic biomarker for the diagnosis and recurrence monitoring of epithelial ovarian carcinoma. MUC16 is highly expressed in varieties of tumors. MUC16 can interact with galectin-1/3, mesothelin, sialic acid-binding immunoglobulin-type lectins-9 (Siglec-9), and other ligands. MUC16 plays an important role in tumor genesis, proliferation, migration, invasion, and tumor immunity through various signaling pathways. Besides, therapies targeting MUC16 have some significant achievements. Related preclinical studies and clinical trials are in progress. MUC16 may be a potential novel target for tumor therapy. This article will review the mechanism of MUC16 in tumor genesis and progression, and focus on the research actuality of MUC16 in tumor therapy. This article also provides references for subsequent tumor therapy studies targeting MUC16.
