Hepatocellular carcinoma (HCC) is one of the major malignant tumors that lead to death, and chronic hepatitis B virus (HBV) infection is an important risk factor for HCC. This article introduces the detailed mechanisms of HBV-related HCC, including HBV X protein, immune imbalance, and integration of HBV DNA into the host genome, with a focus on the pathological role and related mechanisms of HBV X protein in HCC. HBV X protein enhances carcinogenesis by promoting tumor cell proliferation, invasion, and metastasis, affecting angiogenesis, promoting cell apoptosis, and interfering with cell metabolism. In-depth studies on the biological functions of HBV X protein, immune imbalance, and HBV DNA integration will help to clarify the pathogenesis of liver cancer and promote the development of novel therapeutic targets for HBV-related HCC.

In view of the risks in prevention, diagnosis and treatment of venous thromboembolism of inpatients, as well as the key points and difficulties of the quality management for such inpatients, standardized clauses of the standard were developed. This standard, in line with the service process of clinical diagnosis and treatment of the disease, comprises such four core normative parts as disease assessment, disease prevention, disease diagnosis and treatment, and continuous improvement, as well as 16 key points deserving more management efforts. Standardized requirements on quality management, may constrain the medical behavior, and explore a standardized path in accordance with the medical quality management for VTE control of these patients.

Objective: To investigate the clinical value of intraoperative radiofrequency ablation (RFA) in the treatment of colorectal liver metastasis (CLM). Methods: A retrospectively analysis of 187 patients with CLM who underwent liver resection with or without RFA from January 2009 to August 2016 in Department of Hepatobiliary Surgery, Cancer Hospital, Chinese Academy of Medical Sciences was performed. According to whether RFA was used intraoperatively, patients were divided into resection only group and combined treatment group. The clinical and pathological characteristics of the two groups were compared to explore factors influencing survival and recurrence. Imbalance of background characteristics between the two groups was further overcome by propensity score matching method (PSM). Results: The number of liver metastases (267), simultaneous liver metastases (100%), bilobar involvement (73.3%) and preoperative chemotherapy (93.3%) rates were significantly higher in the combined treatment group than those in the resection only group(471, 74.7%, 42.0% and 63.1%)(all P<0.05). In the combined treatment group, median overall survival (OS) was 25.7 months; and 3-year and 5-year OS were 47.9% and 28.8%, respectively. In the resection only group, the median survival time was 46.9 months; and 3-year and 5-year OS rate was 59.1% and 42.4%, respectively (χ²=4.579, P=0.034). Median disease-free survival (DFS) was 5.4 months in the combined treatment group, and 10.1 months in the resection only group (χ²=5.399, P=0.023). In multivariate analysis, intraoperative RFA was not an independent prognostic factor for OS and DFS (HR=0.98, 95%CI: 0.47-2.08, P=0.965; HR=1.21, 95%CI: 0.71-2.07, P=0.465). After PSM, the median OS of the resection only and the combined treatment groups were 30.2 and 25.7 months (χ²=0.876, P=0.350). The median DFS in the two groups was 5.3 and 4.2 months, respectively (χ²=0.199, P=0.650). Conclusion In patients with similar tumor burden, liver resection combined with intraoperative RFA for unresectable CLM can achieve long-term outcomes similar to hepatectomy alone for resectable CLM.

Objective:To investigate the level of functional fitness of elderly hypertensive patients in the community and to analyze its influencing factors.Methods:A cross-sectional survey was used from November 2021 to September 2022, questionnaire survey and Senior Functional Fitness Test (SFT) were conducted on 189 elderly hypertensive patients in the community by convenience sampling method, multiple linear regression was used to analyze the influencing factors of SFT in elderly hypertensive patients in the community.Results:Totally 189 cases of community-aged hypertensive patients completed the investigation, 88 cases were male and 101 were female. The total SFT score of community-aged hypertensive patients was (58.61 ± 16.07). Single factor analysis showed that there were significant differences in SFT scores among patients with different gender, age and education ( t=-2.57, F=6.24, 7.54, all P<0.05). Multifactorial analysis revealed that age ( t=-5.55), gender ( t=2.63), and literacy ( t=5.69) were influential factors in the total SFT scores of community-dwelling elderly hypertensive patients (all P<0.05). Conclusions:Age, gender, and literacy level are the main factors affecting the total SFT scores of elderly hypertensive patients in the community, and community caregivers should pay close attention to the above elderly hypertensive population.

Objective To assess the predictive effect of myocardial injury biomarkers (proBNP, CK-MB, and cTnI) on the severity of acute pancreatitis (AP). Methods The records of 246 patients diagnosed with acute pancreatitis who were treated at Ruijin Hospital Emergency Department from January 2015 to December 2016 were retrospectively analyzed. According to the revised 2012 Atlanta guidelines, these patients were divided into the mild acute pancreatitis (MAP, n=47), moderately severe acute pancreatitis (MSAP, n=151) and severe acute pancreatitis (SAP, n=48) groups. The highest plasma levels of troponin I (cTnI), creatine kinase (CK)-MB, N-terminal B-type brain natriuretic peptide (NT-proBNP), C-reactive protein (CRP), and procalcitonin (PCT) were recorded for comparison within 72 h after admission. The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score, sequential organ failure assessment (SOFA), bedside index for severity in acute pancreatitis (BISAP) and Balthazar computed tomography severity index (CTSI) were calculated at admission within 72 h. Whether there is an occurrence of organ dysfunction, and the organ types and persist time of organ dysfunction were recorded. The analysis of variance, SNK-q test and paired samples t test were used for the statistical analysis. Results The levels of proBNP, CK-MB, and cTnI were significantly higher in the SAP group than in the non-SAP group. The receiver operating characteristic (ROC) curve demonstrated cTnI had the maximum predictive power (AUC=0.872), while proBNP had the least predictive ability (AUC=0.763). The established model, which is to explore whether the myocardial injury markers had the predictive value, showed that the combination of myocardial injury indicators (CK-MB, cTnI) and traditional indicators had higher predictive value for SAP than traditional indicators alone (AUC=0.966 vs. AUC=0.945, P=0.04). Conclusions The elevated markers of myocardial injury had certain predictive value for severe acute pancreatitis.

This paper reviewed the filiform needle insertionmethods in multi-edition of , explored its evolution and reasons, and analyzed its development trend. By referring multi-edition of and related literature regarding acupuncture manipulation published after 1940s, combined with acupuncture manipulation characteristics of modern and contemporary acupuncture masters, it was found that the definition of needle insertion methods needed to be improved after several changes. The classification of needle insertion methods was stable over development. The thrusting method of needle insertion was previously included, and then disappeared. The description of needle insertion methods was improving. These evolutions were mainly influenced by the academic and clinical background, the academic thought of writers and acupuncture masters, the internationalization and standardization of acupuncture and so on. The twist-inserting method and some other needle-inserting instrument meet the safe, sterile, painless and convenient development trend, which might be included in in the future.

Objective: To establish a new scoring system based on the clinicopathological features of hepatocellular carcinoma (HCC) to predict prognosis of patients who received hepatectomy. Methods: A total of 845 HCC patients who underwent hepatectomy from 1999 to 2010 at Cancer Hospital, Chinese Academy of Medical Sciences were retrospectively analyzed. 21 common clinical factors were selected in this analysis. Among these factors, the cut-off values of alpha-fetoprotein (AFP), alkaline phosphatase (ALP) and intraoperative blood loss were evaluated by using a receiver operating characteristic (ROC) curve analysis.The Kaplan-Meier method and Cox regression model were used to evaluate the independent risk factors associated with the prognosis of HCC patients after hepatectomy. HCC postoperatively prognostic scoring system was established according to the minimum weighted method of these independent risk factors, and divided the patients into 3 risk groups, including low-risk, intermediate-risk and high-risk group. The relapse-free survival (RFS) and overall survival (OS) were compared among these groups. Results: The univariate analysis showed that clinical symptoms, preoperative α-fetoprotein (AFP) level, serum alkaline phosphatase (ALP) level, tumor size, tumor number, abdominal lymph node metastasis, macrovascular invasion or tumor thrombus, extrahepatic invasion or serosa perforation, the severity of hepatic cirrhosis, intraoperative blood loss, the liver operative method, pathological tumor thrombus, intraoperative blood transfusion, perioperative blood transfusion were significantly associated with median RFS of these HCC patients (P<0.05). Alternatively, clinical symptoms, preoperative AFP level, serum ALP level, tumor size, tumor number, abdominal lymph node metastasis, macrovascular invasion or tumor thrombus, extrahepatic invasion or serosa perforation, the severity of hepatic cirrhosis, intraoperative blood loss, the liver operative method, pathological lymphocyte invasion, pathological tumor thrombus, intraoperative blood transfusion, perioperative blood transfusion were significantly associated with the median OS of these HCC patients (P<0.05). The multivariate analysis showed that AFP ≥20 ng/ml, clinical symptoms, tumor diameter ≥5 cm, multiple tumors, macrovascular invasion or tumor thrombus, extrahepatic invasion or serosa perforation, moderate and severe liver cirrhosis, non- anatomic resection were the independent risk factors of RFS and OS (P<0.05). The independent risk factor of RFS was intraoperative bleeding loss ≥325 ml (P<0.05); The independent risk factors of OS were abdominal lymph node metastasis and pathological tumors thrombus (P<0.05). The respective weight of 11 independent factors was used to establish the scoring system (scores range from 0 to 26). In the score system, 0 to 5 points were defined as the low-risk group (286 cases), 6 to 12 points were determined as the intermediate-risk group (503 cases), more than 13 points were classified as the high-risk group (56 cases). The median RFS of the low-risk, intermediate-risk and high-risk group were 80, 27 and 6 months, respectively. The differences were statistically significant (P<0.001). The median OS of the three groups were 134, 51 and 15 months, respectively, and the differences were statistically significant (P<0.001). Conclusion This new score system provides effective prediction of postoperative prognosis for HCC patients.
