Gastric adenocarcinoma (GC) is one of the most common malignancies in the world and one of the most frequent causes of cancer-related death.Autophagy is a highly regulated catabolic pathway responsible for the degradation of long-lived proteins and damaged intracellular organelles.However,the mechanism and guiding significance of autophagy in the development and progression of GC have remained to be elucidated.This study aimed to explore the clinicopathological significances and prognostic values of autophagy-related proteins AMBRA1 and Beclin-1 in GC.Quantum dots based immunofluorescence histochemistry (QDs-IHC) was performed to observe the expression of AMBRA1 and Beclin-1 proteins in the tissue rmicroarrays including 163 specimens of GC and 20 noncancerous gastric tissues.Simultaneously,AMBRA1 and Beclin-1 proteins were detected by Western blotting in the 10 fresh GC and corresponding normal gastric tissues.The results showed that the expression levels of both AMBRA1 and Beclin-1 proteins were higher in GC tissues than in noncancerous gastric tissues by QDs-IHC and Western blotting (P<0.05).High AMBRA1 expression was detected in 90 of 163 (55.2%) GCs and high Beclin-1 expression was detected in 83 of 163 (50.9%) GCs.High AMBRA1 expression was closely related to depth of invasion,and lymph nodes metastasis (P<0.05).High expression of Beclin-1 protein was correlated with tumor grade (P<0.05).Positive correlation was observed between AMBRA1 and Beclin-1.Survival analysis indicated the high expression of AMBRA1 and Beclin-1 was an independent factor in predicting poor overall survival (OS) of GC patients.These findings suggest the high expression of AMBRA1 and Beclin-1 proteins is significantly correlated with GC progression.High AMBRA1 and Beclin-1 expression heralds worse outcome of GC patients,suggesting a novel candidate prognostic marker and a therapeutic target for GC.

Objective: To study the effect and mechanism of Shuanghua aerosol (SHA) in treating infantile upper respiratory tract infection. Methods: In the clinical study, 276 patients were randomly divided into two groups. The treated group was treated with SHA and the control group was treated with Shuanghuanglian aerosol (SHLA, 双黄连气雾剂). In the experimental study, the effects of SHA on anti-inflammation and anti-virus were observed. Results: The clinical total effective rate of SHA was 99.03% and its cure rate 65.38%, while those of the SHLA were 94.11% and 44.12% respectively, significant difference was shown between the two groups (P<0.01). Experimental study showed that SHA could inhibit the xylol induced ear swelling and the egg white induced paw swelling in mice obviously, and inhibit the proliferation of influenza virus in rat's lung. Conclusion: SHA has obvious anti-inflammatory and anti-viral effect, and has good curative effect in treating infantile upper respiratory tract infection.

OBJECTIVETo investigate the renin-angiotensin system (RAS) in mesenteric adipose tissues and effect of angiotensin II on adipocyte differentiation.
METHODSThirty normal 8-week-old male Wistar rats were divided into groups on normal diet and high-fat diet. The rats on high-fat diet for 24 weeks developed the metabolic syndrome respectively. The mRNA and protein expression of mesenteric adipose tissue were measured by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. Lipid drop in 3T3-L1 preadipocytes and mature adipocytes were observed using oil-red O staining. The fluorescence microscope was used to detect cytosolic-free calcium in 3T3-L1 preadipocytes and mature adipocytes.
RESULTSThe expressions of angiotensinogen, angiotensin converting enzyme, angiotensin II receptor type 1 in mesenteric adipose tissue were significantly increased in rats with metabolic syndrome compared with those in rats on normal diet (P <0. 05, P <0. 01). After administration of angiotensin II , no lipid droplet in 3T3 -L1 preadipocytes and adipocytes were observed, however, intensive lipid droplet in adipocyte was found after administration of captopril and candesartan. Angiotensin II increased the intracellular-free calcium concentration in preadipocytes (P < 0. 01 ) , which was blocked by captopril and candesartan; in contrast, angiotensin II effect was blunt in mature adipocyte. Captopril and candesartan partially recovered the angiotensin II -mediated increase of cytosolic-free calcium.
CONCLUSIONRAS in the mesenteric adipose tissues is active in rats with metabolic syndrome, and antagonization of RAS can recover the lipogenesis of adipocyte.

OBJECTIVETo explore the relationship between two exonic polymorphisms of DNA repair gene XPC and the susceptibility to lung cancer.
METHODSGenotypes were determined by the primer introduced restriction analysis-PCR(PIRA-PCR) and the PCR-restriction fragment length polymorphism(PCR-RFLP) approaches, respectively, in 320 histologically-confirmed lung cancer cases and 322 age and sex frequency-matched cancer-free controls.
RESULTSMultivariate logistic regression analysis revealed that individuals carrying at least one 499Val variant allele (Ala/Val + Val/Val genotypes) had a significantly increased risk for lung cancer (adjusted OR=1.54; 95%CI: 1.11-2.14), compared with the wild-type genotype (499Ala/Ala). Furthermore, individuals with both putative risk genotypes had a significantly higher risk (adjusted OR=2.55; 95%CI: 1.45-4.52), compared with those with both wild-genotypes. In addition, a potential super multiplicative gene-environment interaction between Ala499Val genotypes and smoking on lung cancer risk was unveiled. The odds ratios of lung cancer for individuals with both putative risk genotypes were 2.63 (95%CI=1.23-5.62) in nonsmokers and 7.36 (95%CI=3.19-17.0) in smokers, respectively.
CONCLUSIONThese findings support the hypothesis that these two XPC variants may contribute to the risk of developing lung cancer.

OBJECTIVETo investigate the expression and the role of secreted frizzled-related protein 2 (SFRP2) in the earlobe keloid and find a valid way to treat the keloid with gene therapy.
METHODSThe expression of SFRP2 mRNA and protein was tested with in situ hybridization and Western Blot Analysis method in the different period of earlobe keloid.
RESULTSThe SFRP2 mRNA and protein expression at the keloid edge was significantly high in 12 month group than in 3 or 6 month groups (P < 0.01), but not than in 24 month group. The SFRP2 expression started to decrease in the keloid center 12 month later (P < 0.01). The SFRP2 expression was always higher in edge than in center during all the period (P < 0.05, P < 0.01).
CONCLUSIONSThe results suggest that SFRP2 may play an important role in the development of keloid, especially at the keloid edge. The high SFRP2 expression in endothelial cells and surrounding tissue is also important. It may be a new way for gene therapy of keloid by decreasing the SFRP2 expression.
