In recent years , increasing use of drugs has given rise to more and more Adverse Drug Reaction ( ADR) cases in China.However, due to the absence of ADR compensation legislation in China , these victim's rights cannot be restituted.By analyzing experiences from Germany , Sweden, Japan, USA, and Taiwan, as well as the current situation and difficulties of ADR compensation in China , this paper provides suggestions for ADR compensa-tion policy in China , which is to constitute an ADR compensation system based on funds .

Objective:To investigate the affects of NOD2 on rapamycin (Rap)induced autophagy and on the proliferation and mi-gration of tongue squamous carcinoma SCC-1 5 cells.Methods:① Synthesized NOD2 over-expression plasmid and NOD2-shRNA were transfected into SCC-1 5 cells respectively.②Normal control SCC-1 5 cells,NOD2 over-expression cells and NOD2-shRNA cells were treated with Rap to induce autophagy.Then,the expression of LC3 and Beclin-1 was examined by Western blot.Cell pro-liferation was tested by MTT assay.Cell migration was assessed by wound healing assay.Results:①After Rap treatment,the expres-sion of protein LC3-Ⅱand Beclin-1 in NOD2 over-expression cells increased(P <0.05)and in NOD2-shRNA cells were suppressed (P <0.05).② Compared with control group,the proliferation and migration ability were decreased in NOD2 over-expression cells (P <0.05),but in NOD2-shRNA cells the proliferation and migration ability were increased(P <0.05).Conclusion:NOD2 can up-regulate the autophagy and suppress the proliferation and migration of tongue squamous SCC-1 5 cells.

Objective:To explore the effects of NOD2 gene on the proliferation and apoptosis of tongue squamous cell carcinoma Tca8113 cells.Methods:NOD2 expression vector(NOD2-pEZ-M29)and NOD2-shRNA vector were established,then were trans-fected into Tca8113 cells respectively.Expressions of HBD-2 and NOD2 in the cells was detected by RT-PCR and Western blot.Cell proliferation was examined by MTT assay and apoptosis by flow cytometry at 48h post transfection.Results:Compared with the control group,the expression of NOD2 and HBD-2 in NOD2-pEZ-M29 transfection group was significantly higher and markedly lower in NOD2-shRNA group.The proliferation rate of Tca8113 cells was markedly lower in NOD2-pEZ-M29 transfection group and signifi-cantly higher in NOD2-shRNA group while the apoptosis rate was significantly higher in NOD2-pEZ-M29 transfection group and sig-nificantly lower in NOD2-shRNA group.Conclusion:In Tca8113 cells NOD2 expression was positively correlated with HBD-2 ex-pression.NOD2 gene may promote the apoptosis,inhibit the proliferation of Tca8113 cells.

OBJECTIVETo investigate the expression characteristics of human beta-defensin-2 (HBD-2) mRNA and protein in salivary gland benign and malignant tumor tissues, as well as in salivary gland inflammation.

METHODSThe expression of HBD-2 in salivary gland benign tumor, salivary gland cancer, inflammation tissues and normal salivary gland tissues were detected by polymerase chain reaction (PCR), real-time polymerase chain reaction (Real-Time PCR) and immunohistochemical. The differences expression of HBD-2 mRNA and protein were analyzed.

RESULTSRT-PCR results showed that HBD-2 mRNA expression in salivary gland benign tumors, salivary gland cancer, and inflammation tissues was 6.468-, 0.334-, and 10.563-fold higher than that in normal tissues, respectively (P < 0.05). HBD-2 was expressed in the nuclei of these organs and malignant tissues.

CONCLUSIONHBD-2 mRNA and protein expressions are significantly increased in salivary gland benign tumor tissues and inflammation tissues compared with those in normal salivary gland tissues, but are significantly decreased in salivary gland cancer. The protein nuclear transfer in salivary gland cancer tissues is also significantly increased.

OBJECTIVE: To establish a scientific foundation for cosmetic supervision and administration based on the analysis of the sanitary quality of cosmetics in Hunan Province during 2010. METHODS: According to Cosmetic Sanitary Standards (set by the Ministry of Health, People's Republic of China), 150 random samples of cosmetics in Hunan were assayed both for microbial items (including total plate count, fungus and yeast, fecal coliform, staphylococcus aureus, pseudomonas aeruginosa) and chemical items (including 17 kinds of prohibited substances and 14 kinds of restricted substances). RESULTS: The total rate of cosmetics failing to meet the standards was 22.0% of the 150 samples; specific rates for failing perfumes, skin care products (eye cream) and deodorant products were, relatively, 70.6%, 60.00%, and 44.4%. Four kinds of prohibited substances, including diethyl phthalate, acrylamide, asbestos and neodymium, as well as 2 kinds of restricted substances, including triclosan and formaldehyde, were found to exceed standards. None of microbial items exceeded standard levels. CONCLUSION The sanitary quality control of cosmetics is lax. Administrative departments should not only reinforce their post-production supervision with respect to cosmetics, but also consolidate their control over the process of cosmetic production in order to solve the problem of toxic residues or illegal and intentional adulterations.

Objective To investigate the effects of long chain non-coding RNA urothelial carcinoembryonic antigen 1(UCA1) on invasion, migration and proliferation abilities in oral squamous cell carcinoma cell lines SCC15 and CAL27.Methods Small interfering RNA of UCA1(UCA1-siRNA) was transfected into SCC15 and CAL27 cell lines by LipofectamineTM 3000 to silence UCA1, and transfected negtive control si-RNA served as a control.The effect of UCA 1-siRNA was detected by quantitative real time-polymerase chain reaction(qRT-PCR) to confirm the successful inhibition of UCA1 by siRNA.The matrix metalloproteinase 9(MMP-9) protein level was detected by Western blotting analysis.The effect of siRNA on cell proliferation and invasion was assessed by transwell migration assay and wound healing assay.Cell counting kit-8(CCK-8) assay was carried out to estimate the proliferation of two cell lines with different expression levels of UCA1.Results Expressions of UCA1 of SCC15 and CAL27 were successfully suppressed after transfected with siRNA which verified by qRT-PCR, and the efficiency of downregulation of SCC15 and CAL27 was 86.45％(P＜0.001)and 78.24％(P＜0.001), respectively.The migration, invasion and proliferation of SCC15 and CAL27 cell lines after transfected with siRNA were obviously restrained.The number of migration and invasion of CAL27 cells were 719.20±92.36 versus 208.00±25.58 (P=0.000 7) and 363.40±45.96 versus 164.80±24.68(P=0.005 2), respectively, the number of migration and invasion of SCC15 cells were 437.20±54.75 vs 145.80±23.31(P=0.001 1) and 249.80±38.41 vs 63.80± 11.11 (P=0.001 6), respectively (UCA1-si compare to negtive control), the relative proliferation rates of SCC 15 and CAL27 were SCC15:R24 h=0.870, R48 h=0.863, R72 h=0.64, R96 h=0.732;CAL27: R24 h=0.913, R48 h=0.829, R72 h=0.756, R96 h=0.705(P＜0.05), and MMP-9 expression level was decreased by UCA1-siRNA compared with negative control.Conclusions UCA1 could enhance the ability of invasion and migration of SCC15 and CAL27 cell lines via regulating MMP-9 protein expression, which suggests that UCA1 might play a pivotal role in oral squamous cell carcinoma invasion and progression.
