Hepatocellular carcinoma (HCC) is a common type of poorly prognosticated malignant tumor. Surgical resection is the preferred treatment method for early-stage HCC. However, at the time of the initial diagnosis, fewer than 30% of patients with liver cancer are suitable for radical therapy. Systemic therapy plays an important role in the treatment process of patients with intermediate- to advanced-stage HCC, as it can effectively extend patients’ survival time. With an emphasis on the status and role of systemic therapy for comprehensive management of HCC, this article summarizes the latest progress at home and abroad in the past five years, including first-line combined immunotherapy for advanced-stage HCC, second-line therapy selection, perioperative systemic therapy application, and combined therapy of systemic and local. Currently, the treatment model combined with local therapy has already become a new research hotspot in the treatment of advanced-stage HCC. Nevertheless, in the future, individualized and precise systemic therapeutic strategies will need further exploration.

Objective To investigate the risk factors for short-term prognosis in patients with HBV-related acute-on-chronic liver failure (ACLF). Methods A retrospective analysis was performed for the clinical data of 119 patients with HBV-related ACLF who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from October 2019 to October 2020, and according to their survival status on day 90, they were divided into death group and survival group. The patients were given antiviral therapy with entecavir or tenofovir. Related clinical data were collected, including alanine aminotransferase (ALT), aspartate aminotransferase, cholinesterase (ChE), albumin (Alb), cholesterol, alpha-fetoprotein, and HBV DNA at baseline, as well as the incidence rate of important complications. Model for End-Stage Liver Disease (MELD) score was also calculated. The t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-squared test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the influencing factors for the 90-day prognosis of patients with HBV-related ACLF and establish a new predictive model; the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of the new model in predicting the prognosis of HBV-related ACLF. Results Of all patients, 33 died within 90 days, resulting in a mortality rate of 27.7%. There were significant differences between the survival group and the death group in age, ALT, Alb, ChE, MELD score, and incidence rates of hepatic encephalopathy, primary peritonitis, and hepatorenal syndrome (all P < 0.05). The logistic regression analysis showed that baseline hepatic encephalopathy (odds ratio [ OR ]=10.404, 95% confidence interval [ CI ]: 2.522-42.926, P =0.001), serum Alb at baseline ( OR =0.853, 95% CI : 0.764-0.952, P =0.005), and MELD score at baseline ( OR =1.143, 95% CI : 1.036-1.261, P =0.008) were independent predictive factors for the short-term prognosis of patients with HBV-related ACLF. A new predictive model was established based on the combination of these three indices, and the ROC curve analysis showed that this new model had an area under the curve of 0.833, while MELD score had an area under the ROC curve of 0.672. Conclusion As for the evaluation of the 90-day prognosis of patients with HBV-related ACLF, the new prognostic model established based on hepatic encephalopathy, Alb, and MELD score has a better predictive value than MELD score alone.

Objective:To investigate and analyze the energy metabolism characteristics and the correlation between energy metabolism and the risk of secondary bacterial infection in patients with hepatitis B virus-related chronic liver disease (HBV-CLD).Methods:Data of 183 cases admitted to the Mengchao Hepatobiliary Hospital of Fujian Medical University from November 2017 to November 2020 were retrospectively analyzed. 79 cases of chronic hepatitis B, 51 cases of hepatitis B-related liver cirrhosis, and 53 cases of hepatitis B-related liver failure were collected. Among them patients with liver failure and decompensated liver cirrhosis were defined as severe liver disease group. The Quark RMR indirect calorimetry (COSMED Corporation, Italy) was used to exam the patients' energy metabolism condition, and the incidences of secondary bacterial infection of the patients during hospitalization were recorded. Shapiro-Wilk test and normal QQ plot were used to analyze the normal distribution of continuous variable data, which was consistent with the normal distribution and was described by mean ± standard deviation. In addition, if it did not conform to the normal distribution, the median and interquartile distance were used to describe it. Levene’s test was used to test the homogeneity of variance of the data, which was consistent with the normal distribution. The t-test was used to compare the means of the two groups of samples. One-way analysis of variance was used to compare the mean values of the three groups of samples, and then the Tukey's test was used to compare the two groups. If the variance was uneven or did not conform to the normal distribution, the Wilcoxon rank sum test was used to compare the differences between the two groups. Kruskal-Wallis test (H test) was used to compare the differences between the three groups of samples, and then the Dunnett’s test (Z test) was used for comparison between the two groups. Categorical variable data were analyzed using chi-square test. Logistic regression analysis was used to screen independent risk factors, and the criteria for variable inclusion ( P < 0.05). Results:The respiratory entropy (RQ) and non-protein respiratory entropy (npRQ) of the three groups had statistically significant difference ( P < 0.05). Among them, the RQ and npRQ of the chronic hepatitis B group were higher than hepatitis B-related liver cirrhosis group and hepatitis B-related liver failure group. There were statistically significant differences in fat oxidation rate (FAT%) and carbohydrate oxidation rate (CHO%) between the three groups ( P < 0.05). Compared with hepatitis B-related liver cirrhosis group and hepatitis B-related liver failure group, chronic hepatitis B group ( P < 0.05) had lower FAT% and higher CHO%. There were no statistically significant differences in the measured and predicted resting energy expenditure and protein oxidation rate (PRO%) between the three groups. The incidence of secondary bacterial infection in patients with severe liver disease was 48.39% (45/93). Compared with the non-infected group, the RQ and npRQ values ??of the infected group were significantly decreased ( P < 0.05), while FAT% was significantly increased ( P < 0.05). Logistic regression analysis showed that glutamyltransferase, cholesterol, and npRQ were independent risk factors for secondary bacterial infections in patients with severe liver disease. Glutamyltransferase elevation, and cholesterol and npRQ depletion had suggested an increased risk of secondary bacterial infection. Subgroup analysis of patients with hepatitis B-related liver failure also showed that compared with non-infected group, RQ value and npRQ value of secondary bacterial infection group were significantly decreased ( P < 0.05), while FAT% was significantly increased ( P < 0.05). Conclusion:Patients with hepatitis B virus-related chronic liver disease generally have abnormal energy metabolism. Low RQ, npRQ, CHO% and high FAT% are related to the severity of the disease; while npRQ reduction is related to the risk of secondary bacterial infection in patients with severe liver disease, and thus can be used as a clinical prognostic indicator.

Surgical treatment is the most effective approach to achieving radical treatment and long-term survival of liver cancer. At present, most patients with intermediate and advanced liver cancer do not have the opportunity to receive radical surgery. The downstaging and conversion treatment strategies for intermediate and advanced liver cancer should be taken seriously in clinical practice to further improve treatment outcome. According to disease stage and conditions of patients with intermediate and advanced liver failure, multidisciplinary cooperation is needed to optimize downstaging and conversion treatment regimens, which may help inoperable patients to obtain the opportunity for surgical treatment. Palliative therapy can be changed to radical surgical resection, and patients who cannot undergo antitumor treatment can still receive palliative therapy. More patients with intermediate and advanced liver cancer are able to achieve a better clinical outcome, an improvement in prognosis, and long-term survival.

OBJECTIVETo assess the association of transcobalamine II (TCN2) gene polymorphisms and serum levels of homocysteine (Hcy), vitamin Band folate with ulcerative colitis (UC) among Chinese patients.

METHODSFor 397 UC patients and 574 controls, two single nucleotide polymorphisms of the TCN2 gene (rs1801198, rs9606756) were tested with an improved multiple ligase detection reaction method. Serum Hcy, vitamin Band folate were measured with an enzymatic cycling assay and an chemiluminescence immunoassay, respectively.

RESULTSThe allelic and genotypic frequencies of rs1801198 and rs9606756 did not differ significantly between the two groups (all P> 0.05). Compared with those of the control group, the frequencies of G allele and CG+GG genotype of rs1801198 were greater in patients with moderate and severe UC (both P< 0.05). The same conclusion may also be drawn for the G allele and AG genotype of rs9606756 (both P< 0.05). Compared with the controls, average Hcy level was enhanced in UC patients (P< 0.01), whereas average vitamin Band folate levels were decreased in UC patients (both P< 0.01). In both groups, the average level of Hcy was lower in individuals carrying CC of (rs1801198) than in those with CG+GG (both P< 0.05). A similar conclusion was also drawn for individuals with AA of rs9606756 when compared with those carrying AG(both P< 0.05). Compared with patients with mild UC, average Hcy level was increased in those with moderate and severe UC (P< 0.01), while average vitamin Band folate levels were decreased in those with moderate and severe UC (both P< 0.01). The prevalence of hyperhomocysteinemia(HHcy), vitamin Bdeficiency and folate deficiency was greater in UC patients than in controls (all P< 0.01). In UC patients, the level of Hcy was negatively correlated with those of vitamin B(P< 0.01), albumin(P< 0.01), red blood cells(P< 0.01) and platelet (P< 0.05), but positively correlated with white blood cells(P< 0.01) and Mayo score (P< 0.01). Both HHcy and folate deficiency were independent risk factors for UC (OR=4.173, OR=5.206, both P< 0.01).

CONCLUSIONTCN2 (rs1801198, rs9606756) variations, as well as serum levels of Hcy, vitamin Band folate, are correlated with UC. Both HHcy and folate deficiency are independent risk factors for UC.
