Lidamycin (LDM) is a potent antitumor antibiotic. Previous studies have shown that LDM could inhibit proliferation and migration in endothelial cells. In the present report, the effect of LDM on angiogenesis of zebrafish embryo was studied. The results showed that treatment of zebrafish embryos with LDM resulted in significant inhibition of angiogenesis. Morphological observation, quantitative endogenous alkaline phosphatase (EAP) assay, alkaline phosphatase staining, and transgenic zebrafish assay were performed to evaluate vascular development defects in zebrafish. The results indicated that after the zebrafish embryos were exposed to LDM, angiogenesis defects of zebrafish embryos were observed, including pericardial edema, reduced numbers of circulating red blood cells, suppression of zebrafish vessel growth, and absences of SIV (subintestinal vein). The expression of VEGF was detected by RT-PCR assay, quantitative reverse transcriptase real-time PCR (qRT-PCR) assay and Western blotting analysis. The results revealed that LDM could inhibit the expression of VEGF protein, while the expression of mRNA was not significantly affected. The study suggests that LDM could inhibit the zebrafish embryo angiogenesis by down-regulation ofVEGF expression.

[Objective] To explore the techniques of hand-assisted laparoscopic splenectomy plus portozygos disconnection procedure. [Methods] 18 patients with portal hypertension were operated by hand-assisted laparoscopic splenectomy plus portozygos disconnection. [Results] The operations were completed successfully. The mean operative time was 180(150～260) minutes, the mean blood loss estimated was 540(200～2 000) mL, the mean weight of spleen was 910 (500～2000) g and the mean length of hospital stay was 9.7 (8～18) days after operation. All patients had recovered rapidly and suffered less pain and only 5 patients needed analgesic. The mean recovery time of the bowel function was 52(24～74) hours. The hand incisions healed well, and only one occurred complications and another suffered death. [ Conclusions ] Hand-assisted laparoscopic splenectomy plus portozygos disconnection procedure is to be feasible and safe, and has the merits of minimally invasive surgery.

Objective To investigate the therapeutic effects of endoscopy for palliative treatment of advanced pancreatic cancer. Methods A typical case of un-resectable advanced pancreatic cancer was reviewed, who underwent obstruction of upper gastrointestinal tract, obstructive jaundice and alimentary tract hemorrhage subsequently. The patient received multiple placement of intestinal tract stents, common bile duct stents and hemostatic treatment endoscopically. Because of the obstruction of upper gastrointestinal tract, jejunalostomy and retrograde endoscopy through the orificium fistulae were performed to place bile duct stents. Results The patient survived for 10 months with good life quality after diagnosis, obstruction of upper gastrointestinal tract, obstructive jaundice and alimentary tract hemorrhage were cured and didn't recur till death.Conclusion Therapeutic endoscopy, safe and effective, is the first choice for advanced pancreatic cancer complicated with obstruction of digestive tract (including gastrointestinal tract, bile duct and pancreatic duct).

Purpose: MicroRNAs play key regulatory roles in the tumorigenesis of hepatitis B virus-related hepatocellular carcinoma (HBVHCC). This study aimed to explore the regulatory effects of microRNA-98-5p (miR-98-5p) on the proliferation, migration, invasion, and apoptosis of HBV-HCC cells, as well as the underlying mechanisms involving nuclear factor-κB-inducing kinase (NIK). Materials and Methods: The expressions of miR-98-5p and NIK in HBV-HCC tissues and cells, and the level of HBV DNA in HBVHCC cells were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The proliferation, migration, invasion, and apoptosis of HBV-HCC cells were analyzed by cell counting kit-8, wound healing, transwell, and flow cytometry assay, respectively. The targeting relationship between miR-98-5p and NIK was predicted by StarBase3.0 and verified by dual-luciferase reporter assay. HBV-HCC xenograft tumor model was constructed in mice to observe the tumor growth in vivo. Results: The expression of miR-98-5p was declined in HBV-HCC tissues and cells. Overexpression of miR-98-5p markedly reduced the level of HBV DNA; inhibited the proliferation, migration, and invasion; and promoted the apoptosis of HBV-HCC cells. NIK was a target of miR-98-5p. Overexpression of miR-98-5p markedly decreased the protein expression of NIK in MHCC97H-HBV cells. NIK reversed the tumor-suppressing effect of miR-98-5p on HBV-HCC cells. Furthermore, overexpression of miR-98-5p significantly inhibited the xenograft tumor growth and decreased the expression of NIK in mice. Conclusion MiR-98-5p inhibits the secretion of HBV, proliferation, migration, and invasion of HBV-HCC cells by targeting NIK.

Objective:To investigate the expressions and significances of autophagy-related genes Beclin-1, LC3 and p62 in esophageal squamous cell carcinoma (ESCC).Methods:The clinical data of 112 patients with primary ESCC who underwent surgery at the 81st Group Army Hospital of Chinese PLA from January 2015 to December 2016 were retrospectively analyzed. Immunohistochemistry was used to examine the expressions of Beclin-1, p62 and LC3 proteins in 112 ESCC tissues and 31 adjacent normal esophageal mucosa tissues. Furthermore, the expressions of the above three autophagy-related markers in ESCC and the relationship between their expressions and the clinicopathological characteristics of patients were analyzed.Results:The positive expression rates of Beclin-1, LC3 and p62 in ESCC tissues were 32.14% (36/112), 37.50% (42/112) and 63.39% (71/112), The positive expression rates of Beclin-1, LC3 and p62 in adjacent normal esophageal mucosa tissues were 61.29% (19/31), 64.52% (20/31) and 32.26% (10/31), and the differences were statistically significant ( χ2 values ??were 8.715, 7.216 and 9.584, all P < 0.01). The positive expression rates of Beclin-1 and LC3 in ESCC were lower than those in adjacent normal esophageal mucosa tissues, and the positive expression rate of p62 in ESCC was higher than that in adjacentnormal esophageal mucosa tissues. In ESCC patients, the expression of Beclin-1 was related to histological grade, infiltration depth, TNM staging and lymph node metastasis (all P < 0.05); the expression of LC3 was related to infiltration depth and TNM staging (both P < 0.01); the expression of p62 was related to lymph node metastasis ( P < 0.01). In ESCC, the expression of LC3 was positively correlated with the expression of Beclin-1 ( r = 0.731, P = 0.001), and negatively correlated with the expression of p62 ( r = -0.215, P = 0.023). Conclusions:Autophagy plays a certain role in the occurrence and development of ESCC. Combined detection of autophagy-related genes Beclin-1, p62 and LC3 can assist clinical diagnosis and guide follow-up comprehensive treatment.
