ABSTRACT
Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer, accounting for 75%-85% of cases. Although treatments are given to cure early-stage HCC, up to 50%-70% of individuals may experience a relapse of the illness in the liver after 5 years. Research on the fundamental treatment modalities for recurrent HCC is moving significantly further. The precise selection of individuals for therapy strategies with established survival advantages is crucial to ensuring better outcomes. These strategies aim to minimize substantial morbidity, support good life quality, and enhance survival for patients with recurrent HCC. For individuals with recurring HCC after curative treatment, no approved therapeutic regimen is currently available. A recent study presented novel approaches, like immunotherapy and antiviral medication, to improve the prognosis of patients with recurring HCC with the apparent lack of data to guide the clinical treatment. The data supporting several neoadjuvant and adjuvant therapies for patients with recurring HCC are outlined in this review. We also discuss the potential for future clinical and translational investigations.
ABSTRACT
Systemic lupus erythematosus (SLE) is a remarkable and challenging autoimmune disorder that is characterized by a broad range of clinical manifestations, such as flares and remissions. Recently, the humanized anti-CD22 antibody epratuzumab for SLE has been extensively studied. The aim of the present study was to perform a meta-analysis on the findings of associated randomized controlled trials in order to evaluate the effects of epratuzumab on SLE. Data from publications in PubMed, EMBASE and the Cochrane Library were collected up to March 2017. To calculate the risk ratio or standardized mean differences (SMDs) with 95% confidence intervals (CIs), a random effect model was applied when heterogeneity was significant and a fixed effect model was used when heterogeneity was negligible. All statistical tests were performed using Review Manager 5.3 software. A total of 1,921 participants in 4 studies (5 trials) that met the selection criteria were analyzed in this meta-analysis. Analyses of the BILAG-based Combined Lupus Assessment (BICLA) response and SLE Disease Activity Index 2000 (SLEDA-2K) score revealed that epratuzumab (720-3,600 mg) significantly improved the BICLA response (RR=1.09; 95% CI, 1.04 to 1.14) and decreased the SLEDA-2K score (SMD=-0.31; 95% CI, -0.67 to 0.06; P=0.10). While the British Isles Lupus Assessment Group index score was not significantly altered between the epratuzumab and control groups. For safety analyses, no statistically significant differences were identified between the two groups, which were proved by the pooled results (all P-values >0.05). These findings suggested that epratuzumab may be relatively safe and may have better therapeutic effectiveness than placebo control conditions in patients with SLE.
ABSTRACT
OBJECTIVE: The study aims to assess the therapeutic benefit of medicine treatment in chronic periaortitis. METHOD: A retrospective study of 52 patients with chronic periaortitis treated at Peking Union Medical College Hospital. Summarize clinical features, level of acute-phase reactants, extent of ureteral obstruction, level of renal function, size of mass with repeated follow-up CT scanning during the period of therapy. RESULTS: The most prominent symtom was back or abdominal pain. 76.92% had ureteral obstruction, with 26.92% had a progressive renal failure. After a period of treatment, 95.35% were significant to complete resolution of symptoms. There was also a remarkable decrease in ESR and C-reactive protein a median treatment of 4 weeks. Creatinine decreased significantly (P = 0.002) in patients with progressive renal failure. 66.67% was successfully removed the ureteric stents. CT scanning showed 75% mass regression after a median of 6 months. CONCLUSIONS: The clinical manifestations of chronic periaortitis is nonspecific, which often leads to a delayed diagnosis and the late complications. Chronic periaortitis is very effectively treated by a combination of steroids and immunosuppressive therapy and(or) tamoxifen, with excellent long-term outcome and relatively fewer disease relapse.

BACKGROUND: Infections caused by gram-negative bacteria (GNB) often lead to high mortality in common clinical settings. The effect of traditional antibiotic therapy is hindered by drug-resistant bacteria and unneutralizable endotoxin. Few effective methods can protect high risk patients from bacterial infection. This study explored the protection of adeno-associated virus 2 (AAV2)-bacteriacidal permeability increasing protein 700 (BPI(700))-fragment crystallizable gamma one 700 (Fc gamma1(700)) chimeric gene transferred mice against the minimal lethal dose (MLD) of E. coli and application of gene therapy for bacterial infection. METHODS: After AAV2-BPI(700)-Fc gamma1(700) virus transfection, dot blotting and Western blotting were used to detect the target gene products in Chinese hamster ovary-K1 cells (CHO-K1cells). Reverse transcription-polymerase chain reaction and immunohistochemical assay were carried out to show the target gene expression in mice. Modified BPI-enzyme linked immunosorbent assay was used to identify the target gene products in murine serum. The protection of BPI(700)-Fc gamma1(700) gene transferred mice was examined by survival rate after MLD E. coli challenge. Colony forming unit (CFU) count, limulus amebocyte lysate kit and cytokine kit were used to quantify the bacteria, the level of endotoxin, and proinflammatory cytokine. RESULTS: BPI(1-199)-Fc gamma1 protein was identified in the CHO-K1 cell culture supernatant, injected muscles and serum of the gene transferred mice. After MLD E. coli challenge, the survival rate of AAV2-BPI(700)-Fc gamma1(700) gene transferred mice (36.7%) was significantly higher than that of AAV2-enhanced green fluorescent protein (AAV2-EGFP) gene transferred mice (3.3%) and PBS control mice (5.6%). The survival rate of AAV2-BPI(700)-Fc gamma1(700) gene transferred mice treated with cefuroxime sodium was 65.0%. The bacterium number in main viscera, the levels of endotoxin and proinflammatory cytokine (tumor necrosis factor-alpha and interleukin-1beta) in serum of the AAV2-BPI(700)-Fc gamma1(700) gene transferred mice were markedly lower than that of PBS control mice (P < 0.01). CONCLUSIONS: AAV2-BPI(700)-Fc gamma1(700) gene transferred mice can resist MLD E. coli infection through expressing BPI(1-199)-Fc gamma1 protein. Our findings suggested that AAV2 mediated BPI(700)-Fc gamma1(700) gene delivery could be used for protection and treatment of clinical GNB infection in high-risk individuals.
