Tumor lysis syndrome (TLS) is a potentially lethal complication in cancer therapy. It may occur in highly sensitive tumors, especially in childhood cancer and leukemia, whereas, it is rare in the treatment of solid tumors in adults. TLS results from a sudden and rapid release of nuclear and cytoplasmic degradation products of malignant cells. The release of these can lead to severe alterations in the metabolic prof ile. Here, we present two cases of large hepatocellular carcinoma (HCC) treated by transarterial chemoembolization (TACE) that resulted in TLS. Although TLS rarely happens in the treatment of adult hepatic tumor, only a few cases have been reported. We should keep in mind that all patients with HCC, particularly those with large and rapidly growing tumors, must be closely watched for evidence of TLS after TACE.

BACKGROUND Recurrent hepatocellular carcinoma(rHCC)is a common outcome after curative *** for rHCC is recommended,but no guidelines *** To compare curative treatments such as repeated hepatectomy(RH),radiofrequency ablation(RFA),transarterial chemoembolization(TACE)and liver transplantation(LT)for patients with rHCC after primary hepatectomy by conducting a network meta-analysis(NMA).METHODS From 2011 to 2021,30 articles involving patients with rHCC after primary liver resection were retrieved for this *** Q test was used to assess heterogeneity among studies,and Egger’s test was used to assess publication *** efficacy of rHCC treatment was assessed using disease-free survival(DFS)and overall survival(OS).RESULTS From 30 articles,a total of 17,11,8,and 12 arms of RH,RFA,TACE,and LT subgroups were collected for *** plot analysis revealed that the LT subgroup had a better cumulative DFS and 1-year OS than the RH subgroup,with an odds ratio(OR)of 0.96(95%CI:0.31-2.96).However,the RH subgroup had a better 3-year and 5-year OS compared to the LT,RFA,and TACE *** step diagram of different subgroups measured by the Wald test yielded the same results as the forest plot *** had a better 1-year OS(OR:1.04,95%CI:0.34-03.20),and LT was inferior to RH in 3-year OS(OR:10.61,95%CI:0.21-1.73)and 5-year OS(OR:0.95,95%CI:0.39-2.34).According to the predictive P score evaluation,the LT subgroup had a better DFS,and RH had the best ***,meta-regression analysis revealed that LT had a better DFS(P<0.001)as well as 3-year OS(P=0.881)and 5-year OS(P=0.188).The differences in superiority between DFS and OS were due to the different testing methods *** According to this NMA,RH and LT had better DFS and OS for rHCC than RFA and ***,treatment strategies should be determined by the recurrent tumor characteristics,the patient’s general health status,and the care program at each institution.

AIM： TO elucidate the prognostic role and relationship of three molecular markers such as tumor suppressor gene p53, proliferating cell nuclear antigen （PCNA） and Ki-67 in gastric stromal tumor. METHODS： A total of 108 surgically resected gastric smooth muscle tumor specimens were collected from January 1987 to December 1999. Immunohistochemical studies were performed on the paraffin sections of 99 of 108 CDl17-positive tumors with antibodies of p53, PCNA, and Ki-67. Immunoreactivity of three molecular markers was recorded by labeling index （LI, %） and was analyzed for clinicopathologic and survival correlation. RESULTS： Of the 99 cases, immunostaining revealed that 52 patients （52.5%） had p53, and 37 patients （37.3%） had Ki-67 immunoreactivity （defined as 〉10% of LI）. All patients （100%） had PCNA immunoreactivity ranging from 12% to 93% of LI, divided into high or low by median. Statistics revealed that LI of three markers positively correlate to each other （P〈0.01） and to microscopic tumor mitotic counts （P〈0.001）. By combination, patients with ≥2 markers （positive or high） in tumors had early tumor recurrence （P〈0.001） and unfavorable outcome （P〈0.001）. Univariate analysis indicated that patients with tumor size 〉5 cm （P=0.003）, tumor mitosis 〉5/50 HPF （P〈0.001）, p53 immunoreactivity （P=0.001）, Ki-67 immunoreactivity （P=0.026）, high PCNA LI （P=0.015） and male gender （P=0.036） were six predictors for early disease recurrence. Subsequent multivariate analysis revealed that mitotic counts, tumor size, and p53 immunoreactivity were three independent prognostic factors for both disease free and overall survival of patients. By combination of three independent prognostic factors for grouping, we found higher tumor recurrence rate （P〈0.001） and shorter survival （P〈0.001） existed in groups with increasing factors. CONCLUSION： We first provide the prognostic value and linkage of three molecular markers in GISTs. The combination of three factors （p53, tumor size, and t

AIM： To analyze 67 cases of splenic abscess in a medica center of Taiwan during a period of 19 years. METHODS： From January 1986 to December 2004, a total of 67 patients with splenic abscess were enrolled for the retrospective study. The clinical characteristics, underlying diseases, organism spectra, therapeutic methods, APACHE Ⅱ scores, and mortality rates were analyzed. RESULTS： There were 41 males and 26 females with the mean age of 54.14-14.1 years. Multiple splenic abscesses （MSA） account for 28.4% and solitary splenic abscess in 71.6% of the patients. Twenty-six of sixtyseven patients （35.8%） had extrasplenic abscesses, with leading site of liver （34.6%）, Microbiological cultures were positive in 58 patients （86.6%）, with 71.8% in blood culture and 93.5% in abscess culture. Gram negative bacillus （GNB） infection predominated （55.2%）, with leading pathogen of Klebslella pneumoniae （22.4%）, followed by gram positive coccus （GPC） infection （31%）. Splenectomy was performed in 26 patients （38.8%）, percutaneous drainage or aspiration in 21 （31.3%）, and antibiotic therapy alone in 20 patients （29.9%）. Eventually, 12 of 67 patients expired （17.9 %）. By statistics, spleen infected with GNB was likely to develop multiple abscesses compared with infection with GPC （P=0.036）. Patients with GNB infection （P=0.009） and multiple abscesses （P=0.011） experienced a higher mortality rate than patients with GPC infection and solitary abscess. The mean APACHE Ⅱ score of 12 ex- pired patients （16.3±3.2） was significantly higher than that of the 55 survivals （7.2 ± 3.8）（P〈 0.001）. CONCLUSION： MSA, GNB infection, and high APACHE Ⅱ scores are poor prognostic factors. Early surgical intervention should be encouraged when these risk factors are present.

AIM: Hyperglycemia commonly seen in liver transplantation (LT) has often been attributed to the dextrose in the storage solution of blood transfusion products. The purpose of the study is to compare the changes of the blood glucose levels in transfused and non-transfused patients during LT. METHODS: A retrospective study on 60 biliary pediatric patients and 16 adult patients undergoing LT was carried out. Transfused pediatric patients were included in Group Ⅰ (GⅠ), those not transfused in Group Ⅱ (GⅡ). Twelve adult patients were not given transfusion and assigned to Group Ⅲ(GⅢ); whereas, four adult patients who received massive transfusion were assigned to Group Ⅳ (GⅣ). The blood glucose levels, volume of blood transfused, and the volume of crystalloid infused were recorded, compared and analyzed. RESULTS: Results showed that the changes in blood glucose levels during LT for both non-transfused and minimally transfused pediatric groups and non-transfused and massively-transfused adult groups were almost the same. CONCLUSION: We conclude that blood transfusion does not cause significant changes in the blood glucose levels in this study.

Recent advancements in attribute localization have showcased its potential in discovering the intrinsic semantic knowledge for visual feature representations, thereby facilitating significant visual-semantic interactions essential for zero-shot learning(ZSL). However, the majority of existing attribute localization methods heavily rely on classification constraints, resulting in accurate localization of only a few attributes while neglecting the rest important attributes associated with other classes. This limitation hinders the discovery of the intrinsic semantic relationships between attributes and visual features across all *** address this problem, we propose a novel attribute localization refinement(ALR) module designed to enhance the model's ability to accurately localize all attributes. Essentially, we enhance weak discriminant attributes by grouping them and introduce weighted attribute regression to standardize the mapping values of semantic attributes. This module can be flexibly combined with existing attribute localization *** experiments show that when combined with the ALR module, the localization errors in existing methods are corrected, and state-of-the-art classification performance is achieved.
