To study the inhibitory effect of gigantol on proliferation, migration and invasion of human osteosarcoma U20S cells and to explore the mechanism. Methods: After being treated with different concentrations (10, 25, 50, 75, 100, 150 µmol/L) of gigantol for 24 and 48 h, the proliferation of U20S cells was detected by CCK-8 assay. Transwell assay was used to detect the effects of 25 µmol/L and 50 µmol/L gigantol on the migration and invasion abilities of U20S cells. The lipopolysaccharide (LPS) was used to induce inflammatory reaction in U20S cells before gigantol treatment; qPCR and WB were used to detect the mRNA and protein expressions of NF-κB (p65), TNF-α, IL-6 and PRL-3, respectively. Results: Different concentrations of gigantol could all inhibit the proliferation of sarcoma U20S cells at different time (P<0.05 or P<0.01). The 25 µmol/L and 50 µmol/L of gigantol could significantly inhibit the migration and invasion of osteosarcoma U20S cells (all P<0.01); at the same time, it could inhibit the protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 (P<0.05 or P<0.01). After LPS induction, the mRNA and protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 in U20S cells were significantly increased (all P<0.01); however, the consequent treatment with gigantol (25 and 50 µmol/L) reversed the effects of LPS on U20S cells obviously (P<0.05 or P<0.01). Conclusion: Gigantol can inhibit the proliferation, migration and invasion of osteosarcoma U20S cells, and its mechanism may be related to the regulation of NF-κB/PRL-3 signaling pathway.

5.Clinical observation on treatment of functional constipation with compound plantain-senna granules.
Chinese Journal of Integrated Traditional and Western Medicine 2009;29(12):1119-1122
OBJECTIVETo investigate the efficacy and safety of compound plantain-senna granule (CPSG) in the treatment of functional constipation.
METHODSEighty patients with confirmed diagnosis of functional constipation were assigned to 2 groups. The 40 patients in the treatment group were treated with CPSG 5 g per day, while the 40 patients in the control group were treated with equal volume of starch granule, for 2 weeks totally. The defecating frequency and stool property, the scores of fecal discharge difficulty and accompanied symptoms, the gastrointestinal transmission time, and adverse reaction of treatment in the two groups were observed before and after treatment.
RESULTSParameters of defecating frequency, stool property, the scores of fecal discharge difficulty, accompanied symptoms and the gastrointestinal transmission time were unchanged after treatment in the control group (P > 0.05); while in the treatment group, they improved significantly (P < 0.05) and showed significant difference to those in the control group respectively (P < 0. 05). No serious adverse reaction occurred in both groups.
CONCLUSIONCPSG can obviously increase the defecating frequency, change the stool property, alleviate the fecal discharging difficult symptom and accompanied symptom, and shorten the gastrointestinal transmission time in patients with functional constipation with good security and tolerability.

Objective To investigate the correlation between drinking behavior combined with polymorphisms of extracellular superoxide dismutase (EC-SOD) and aldehyde dehydrogenase-2 (ALDH2) genes and pancreatic cancer.
Methods The genetic polymorphisms of EC-SOD and ALDH2 were analyzed by polymerase chain reaction restriction fragment length polymorphism in the peripheral blood leukocytes obtained from 680 pancreatic cancer cases and 680 non-cancer controls. Subsequently the frequency of genotype was compared between the pancreatic cancer patients and the healthy controls.The relationship of drinking with pancreatic cancer was analyzed.
Results The frequencies of EC-SOD (C/G) and ALDH2 variant genotypes were 37.35% and 68.82%respectively in the pancreatic cancer cases, and were significantly higher than those in the healthy controls (21.03% and 44.56%, all P<0.01). People who carried EC-SOD (C/G) (OR=2.24, 95% CI=1.81-4.03, P<0.01) or ALDH2 variant genotypes (OR=2.75, 95%CI=1.92-4.47, P<0.01) had a high risk to develop pancreatic cancer. Those who carried EC-SOD (C/G) genotype combined with ALDH2 variant genotype had a high risk for pancreatic cancer (29.56%vs. 6.76%, OR=7.69, 95%CI=3.58-10.51, P<0.01). The drinking rate of the pancreatic cancer group (64.12%) was significantly higher than that of the control group (40.15%; OR=2.66, 95% CI=1.30-4.42, P<0.01). An interaction between drinking and EC-SOD (C/G)/ALDH2 variant genotypes increased the risk of occurrence of pancreatic cancer (OR=25.00, 95%CI=11.87-35.64, P<0.01).
Conclusion EC-SOD (C/G), ALDH2 variant genotypes and drinking might be the risk factors of pancreatic cancer.

With the advent of Twenty-First century, more and more genome-wide association studies (GWAS) showed that idiosyncratic adverse drug reactions (ADRs) were closely related with human leukocyte antigen (HLA) alleles, such as the associations of abacavir-HLA-B*5701, allopurinol-HLA-B*5801, and carbamazepine-HLA-B*1502, etc. To explore the mechanisms of these idiosyncratic drug reactions, hapten hypothesis, danger signal hypothesis, pharmacological interaction (P-I) concept and autoimmune mechanism are proposed. In this paper, recent GWAS studies on the HLA-mediated adverse drug reactions and underlying mechanism are reviewed in detail.

Objective To explore the activation and function of Janus protein-tyrosine kinase (JAK)/ signal transducer and activator of transcription (STAT1) signal transduction pathway in kidney,lung and brain of MRL/lpr mice.Methods MRL/lpr mice with systemic lupus erythematosus (SLE) were studied at the age of 12 weeks up.Non-SLE MRL/lpr mice were used as controls.We used phosphospecific antibodies to detect STAT1 activation in kidney,lung and brain by immunohistochemistry and Western blots.Gene expression of the STAT induced feedback inhibitors of cytokine signaling 1 (SOCS-1) was investigated by SYBR green I real-time reverse transcriptase polymerase chain reaction (PCR).Results Phosphorylation of STAT1 protein was markedly activated in these three organs,although renal and pulmonary STAT1 activation were much more evidently activated.SOCS-1 gene expression increased in all three organs,while renal SOCS-1 gene expres- sion increased less than lung and brain.Conclusion The activation of JAK/STATI signal transduction path- way may be pathogenic in the organ involvement and progression of SLE.The pathogenesis of lupus nephritis may also be associated with the down-regulation of SOCS-1 feedback inhibition.
