Objective To evaluate the effects of alpha-lipoic acid (α-LA)on autophagy in human skin fibroblasts (HSFs). Methods HSFs at passage 3 - 5 were divided into several groups to be cultured with α-LA at final concentrations of 0, 0.01, 0.05, 0.10, 0.15, 0.20 and 0.50 mmol/L for 4, 12 and 24 hours, respectively. Methyl thiazolyl tetrazolium(MTT)assay was performed to evaluate cellular proliferative activity, monodansylcadaverin(MDC)staining to determine autophagy levels, and Western blot to measure the expression of the microtubule-associated protein 1 light chain-3B(LC3-B). Results After incubation for 24 hours, there was a significant difference in the proliferative activity of HSFs among all the groups (F = 10.41, P < 0.05), while no significant differences were observed after incubation for either 4 or 12 hours (F = 2.85, 1.34, respectively, both P > 0.05). MDC staining also showed a significant difference in the percentage of autophagosome-positive cells among all the groups after 24-hour incubation (F = 8.03, P < 0.05), but no significant difference after either 4- or 12-hour incubation (F = 0.11, 0.10, respectively, both P > 0.05). Western blot revealed that the degree of conversion from LC3-Ⅰ to LC3-Ⅱ(LC3-Ⅱ/LC3-Ⅰratio)was significantly different among all the groups after 24-hour incubation (F = 37.49, P < 0.05), but similar after 4- and 12-hour incubation (F = 3.38, 2.13, respectively, both P > 0.05). Conclusion α-LA may inhibit basal autophagy in HSFs.

OBJECTIVE:
This study aimed to explore the expression and their correlation of mammalian target of rapamycin (mTOR) and EIF4E binding protein1 (4EBP1) in laryngeal squamous cell carcinoma (LSCC).
METHOD:
MTOR and 4EBP1 expression was studied using immunohistochemical methods in LSCC tissues of 77 cases and adjacent tissues of 18 cases,and then the relationship of their expression and clinical pathological factors were analyzed.
RESULT:
The positive expression rates of mTOR and 4EBP1 were 54.5% and 48.1% in laryngeal carcinoma, which was significantly higher than those in para-carcinoma (P < 0.05). Expression of mTOR and 4EBP1 was associated with metastases to lymph nodes and histopathology classification (P < 0.05), but was not associated with clinic stages (P > 0.05). There was significant positive correlation between the expression level of mTOR and 4EBP1 in LSCC (P < 0.05).
CONCLUSION
(1) The high expression of mTOR and 4EBP1 is closely related with clinicopathology and lymph node metastases. It may play an important role in the development and progression of laryngeal carcinoma. (2) The positive correlation on expression level of mTOR and 4EBP1 in LSCC tissue shows that it has clinical significance on clinical therapy and prognosis.

Objective To study the effects of decoy strategy targeted to NF-KB on the development of trauma-associated liver inflammation in rats. Methods In this study, 108 Wistar rats were randomized into 3 groups: control group, traumatic inflammation group and traumatic inflammation plus decoy ODN group. Rats were sacrificed on 3,6,12,24,48 and 72hrs in each group respectively. Liver functions and structural changes were examined and compared between the groups. DNA binding activity of NF-KB in liver tissue was measured by EMSA. TNF-α and IL-6 gene expressin in liver tissue was assessed by RT-PCR and TNF-α and IL-6 protein level was determined by ELISA. Results The DNA binding activity of NF-kB in liver rose at 3 hours after induction of liver inflammation following trauma and peaked at 12 hours. Correspondingly, both the mRNA and protein levels of TNF-α and IL-6 elevated significantly, as well as the serum alanine aminotransferase level culminating at 24 hours after surgery. Hepatocytes was edematous, degeneration and necrosis, with dramatic destruction of lobular structures. All these changes were significantly inhibited with NF-KB decoy oligodeoxynucleotides. Conclusions Decoy oligodeoxynucleotides specifically inhibit the activity of NF-kB, and the release of pro-inflammatory cytokines, TNF-α and IL-6 release from the liver in response to traumatic inflammation decrease, hence the injury on liver structures and functions were alleviated.
