Systematic Review and Meta-analysis of Endostar Combined With Transcatheter Arterial Chemoembolization (TACE) Versus TACE Alone for Hepatocellular Carcinoma.

Many studies have investigated the efficacy of Endostar combined with transcatheter arterial chemoembolization (TACE) versus TACE alone for hepatocellular carcinoma (HCC). A systematic review was conducted to evaluate the efficacy of Endostar. PubMed, Embase, and other databases were searched, and meta-analysis was performed using RevMan 5.3 software. Nine studies, all of which were clinical randomized controlled trials, involving 411 participants were included. The overall response rate, disease control rate and α-fetoprotein negative conversion ratio, and the 6- and 12-month survival rate of HCC patients treated with combined Endostar and TACE were higher than those treated with TACE alone ( P < .01). Furthermore, the incidence of tumor progression was low after Endostar treatment ( P = .005). The incidence of adverse effects (leukocytopenia, liver function damage, and vomiting) was similar in Endostar with TACE and in TACE alone ( P > .05). However, large studies and more randomized trials are necessary to determine the effects of Endostar on HCC.

Synergistic Apoptotic Effect of D-Fraction From Grifola frondosa and Vitamin C on Hepatocellular Carcinoma SMMC-7721 Cells.

The aim of this study was to investigate the anticancer effect of a combination of D-fraction polysaccharide from Grifola frondosa (DFP) and vitamin C (VC) on hepatocellular carcinoma in vitro. DFP is a bioactive extract from the maitake mushroom. Anticancer activity was demonstrated using various concentrations of DFP alone or in combination with VC against the human hepatocarcinoma SMMC-7721 cell line. To investigate the anticancer mechanism, studies designed to detect cell apoptosis were conducted. Results from the MTT assay indicated that a combination of DFP (0.2 mg/mL) and VC (0.3 mmol/L) led to a 70% reduction in cell viability. Flow cytometry results indicated that DFP/VC treatment induced apoptosis in approximately 65% SMMC-7721 cells. Cell cycle analysis identified cell cycle arrest at the G2/M phase following DFP/VC treatment for 48 hours. In addition, cellular morphological changes were observed using transmission electron microscopy. Western blot analysis revealed that the upregulation of BAX, downregulation of Bcl-2, activation of poly-(ADP-ribose)-polymerase (PARP), and the release of cytochrome c were observed in cells treated with the combination of DFP/VC, which showed that the mechanism of anticancer activity in the SMMC-7721 hepatocarcinoma cells involved induction of apoptosis.

Perineural dexamethasone does not enhance the analgesic efficacy of ultrasound-guided subcostal transversus abdominis plane block during laparoscopic cholecystectomy.

BACKGROUND: Ultrasound-guided transversus abdominis plane (TAP) block is an adjunct therapy to provide effective postoperative analgesia in abdominal surgical procedures. Dexamethasone is a supplement agent that can improve the efficacy of local anesthesia. However, information about its additive effect is limited. This study aimed to compare the analgesic efficiency using ultrasound-guided TAP block with and without perineural dexamethasone for patients who underwent laparoscopic cholecystectomy. METHODS: Sixty patients who underwent laparoscopic cholecystectomy were randomly divided into three groups: group I, controls; group II, TAP; and group III, TAP+perineural dexamethasone supplement. The requirement of additional analgesia and the first-time request of rescue-analgesia were recorded after operation and the numerical rating scale was evaluated at specific intervals. RESULTS: Compared to group I, the first-time requirement of rescue-analgesia in groups II and III was significantly delayed (403.0+/-230.9, 436.0+/-225.3 vs 152.3+/-124.7, P<0.01). Compared with those in group I, patients in groups II and III were associated with lower numerical rating scale pain scores (P<0.01) and less postoperative analgesic consumption (P<0.01). There was no significant difference in the variables mentioned above between groups II and III (P>0.05). CONCLUSION: Perineural dexamethasone has no additive/synergistic effect with subcostal TAP block on analgesic efficacy for the patients undergoing laparoscopic cholecystectomy.
