Osteoarthritis(OA)is a common concern over the world.Garlic is a kind of natural herbal medicine,and its active ingredients have shown some anti-inflammatory,antioxidant,anti-catabolic,analgesic and other phar-macological effects.Garlic and its active components alleviate the inflammatory response of OA by inhibiting the ex?pression of inflammatory factors and signal pathways such as NF?κB and PI3K/Akt.They slow down the progression of OA by inhibiting the expression of extracellular matrix(ECM)degrading enzymes.Additionally,they reduce the oxidative damage of joints by upregulating the expression of antioxidant enzymes.Moreover,the active components of garlic can relieve OA pain by activating the potassium ion pathway(Kv7),ATP?sensitive potassium channel(K?ATP),and the nuclear factor erythroid 2?related factor 2(Nrf2)/heme oxygenase 1(HO?1)?NAD(P)H:qui?none oxidoreductase 1(NQO1)signaling pathway.

Phosphorylation is a common post-translational modification of specific protein 1(SP1),which can affect its transcriptional activity and DNA-binding stability by altering the structure of SP1.Phosphorylation of SP1 can promote telomere maintenance,immune escape,and production of vascular endothelial growth factor in cancer cells,promote tumor invasion and metastasis,and increase drug resistance to chemotherapy.

Objective: To examine the causal relationship between inflammatory factors and breast cancer using two-sample Mendelian randomization (MR) approach, so as to provide the basis for the prevention and treatment of breast cancer. Methods: Data of 91 inflammatory cytokines (n=14 824) and 5 subtypes of breast cancer (n=247 173) were collected from genome-wide association studies (GWAS). Single nucleotide polymorphism (SNP) associated with 91 inflammatory factors were selected as instrumental variables. MR analyses were performed using the inverse-variance weighted (IVW) method with inflammatory factors as exposure factors and breast cancer as outcome variables. The risk of type I error and the effect of multiple testing were reduced using the FDR correction method. The stability and reliability of the results were verified using Steiger test of directionality, MR-Egger regression, MR-PRESSO test and leave-one out method. Results: Twenty-three inflammatory factors, including β nerve growth factor, interleukin-5, cystatin D and C-X-C chemokine ligand 1 were statistically associated with breast cancer (all P<0.05). After FDR adjustment, only evaluated abundance of oncostatin-M was found to be statistically associated with an increased risk of Basal-like (triple-negative) breast cancer (OR=1.186, 95%CI: 1.081-1.302, P=0.001, q=0.029), and the other 22 inflammatory factors had a high risk of type I error (all q>0.1). The sensitivity analysis indicated that the results were robust. No instrumental variables were found to have a significant impact on the results, which could exclude the influence of heterogeneity, horizontal pleiotropy, and reverse causality on the outcome. Conclusion The increased abundance of oncostatin-M may increase the risk of Basal-like (triple-negative) breast cancer.

Objective: To explore the clinical and prognostic features of lipoprotein glomerulopathy (LPG) in renal allografts. Methods: Retrospective analysis was performed for two case of LPG in renal allografts. The onset time was 6 and 9 years after living transplantation respectively. Initial symptoms included proteinuria and hypoproteinemia. Color Doppler ultrasound showed an enlarged graft size and greater parenchymal echogenicity. One patient had hyperlipemia and elevated apolipoprotein E (ApoE). Methylprednisolone pulse was offered with an early control of hyperlipidaemia and proteinuria by fenofibrate and angiotensin-converting enzyme inhibitors (ACEIs). Yet it had no effect on graft function. The definite diagnosis was made by graft biopsy. Pathological examination indicated non-homogeneous lipid deposition in glomerular capillary, glomerular sclerosis, mesangial hypercellularity and tubular atrophy. Results: During a follow-up period of 8 and 10 years post-transplantation, two cases eventually lost their grafts within 2 and 1 year after biopsy respectively. With long-term dietary control and drug therapy, regular dialysis continued and both awaited a second transplantation. Conclusions LPG is generally steroid-resistant and refractory in renal allografts. And routine biopsy is recommended for patients with a high risk of occurrence. Early controls of hyperlipemia and hypoproteinemia and other risk factors should be also properly managed.

OBJECTIVETo investigate the role of miR-26b in the invasion and metastasis of colorectal cancer.

METHODSData of public chip databases were extracted to analyze the relationship between miR-26b expression and lymph node metastasis. Two types of colorectal cancer cell lines, Caco2 and DLD1, were selected, and the miR-26b-high colorectal cancer cell line was constructed using the method of lentivirus infection. The effects of up-regulating miR-26b expression on the invasion and metastasis of colorectal cancer cells were analyzed by Transwell migration and invasion experiment and wound healing assay. The effect of up-regulating miR-26b expression on stem cell phenotype of colorectal cancer cells was analyzed by sphere-formation assay.

RESULTSThe microarray detection results showed that the expression of miR-26b in tumor tissues of patients with lymph node metastasis was significantly higher than those without lymph node metastasis[(12.04±0.20) vs. (11.31±0.19), t=2.646, P = 0.010]. In the in vitro experiment section, the Transwell experiment results showed that the number of invasive cells [(16.40±1.36) vs. (3.80±0.86), t=7.814, P=0.000] and migrating cells [(33.40±2.93) vs. (8.80±2.40), t=6.505, P=0.000] in miR-26b-high colorectal cancer cells was significantly higher as compared to miR-26b-low cells(all P<0.05). Would healing assay also confirmed that the migration speed of miR-26b-high colorectal cancer cells was significantly accelerated. Both the rate and the density of sphere formation were higher in miR-26b-high colorectal cancer cells than those in miR-26b-low colorectal cancer cells [Caco2:(168.3±11.7) vs. (54.2±10.8), t=7.185,P=0.002; DLD1:(4 076.0±409.8) vs.(1 613.0±210.1), t=5.349, P=0.006].

CONCLUSIONmiR-26b may promote the invasion and metastasis of colorectal cancer by accelerating the migration and invasion of colorectal cancer cells and enhancing the stem cell phenotype of tumor cells.

OBJECTIVETo investigate the influence of CCL21 on the invasion and metastasis of colorectal cancer (CRC).

METHODSCCL21 over-expressing CRC cell line was constructed by lentivirus infection and CCL21 low-expressing CRC cell line was constructed by lipofection. The effects of CCL21 on the invasion and metastasis of CRC cells and the stem cell-like phenotype were investigated by Transwell migration, invasion assay, wound healing assay and sphere formation assay.

RESULTSReal-time quantitative PCR and western blot confirmed that the expression of CCL21 was up-regulated by lentiviral transfection and down-regulated by siRNA liposome transfection. In vitro, Transwell assays showed that the invasion and migration in CCL21 over-expressing CRC cells decreased significantly as compared to those of CCL21 low-expressing cells. In wound healing assay, the CCL21 over-expressing CRC cells showed a significantly lower rate of migration. In addition, the sphere formation rate and density of CCL21 over-expressing CRC cells were lower than those with low-expression of CCL21.

CONCLUSIONCCL21 can suppress the migration and invasion of CRC cells and weaken their stem cell-like phenotype.

OBJECTIVETo investigate the expression and clinical significance of G protein-coupled receptor 31 (GPR31) in colorectal cancer tissue.

METHODSCancer tissues and adjacent normal tissues of 321 cases with colorectal cancer confirmed by pathology and undergoing resection in the First Affiliated Hospital of Sun Yat-sen University from January 1996 to December 2008 were collected. The expression of GPR31 was examined by immunohistochemical staining. According to the expression level of GPR31 (A value=0.051), all the patients were divided into low GPR31 expression group and high GPR31 expression group. Clinicopathology and prognosis between the two groups were compared. Risk factors affecting prognosis were investigated.

RESULTSGPR31 expression was significantly higher in colorectal cancer tissues compared to adjacent normal tissues (mean A, 0.063±0.014 vs. 0.045±0.020, P<0.001). A total of 197 cancer tissue samples were defined as low expression and 124 as high expression. Significant difference was observed in the number of patient in pM classification between the two groups (P=0.007). High expression group had obviously higher distant metastasis rate than low expression group [12.1% (15/124) vs. 4.1% (8/197), P=0.007]. The 5-year survival rate and tumor-free survival rate were 84.3% and 82.2% in the low expression group, and both 59.7% in high expression group (all P<0.05). Multivariate analysis revealed elderly, abnormal CEA, lymphatic metastasis, distant metastasis and up-regulated GPR31 expression were independent risk factors of overall survival and disease-free survival in colorectal cancer patients (all P<0.05).

CONCLUSIONSGPR31 expression is significantly up-regulated in colorectal cancer tissues. High GPR31expression indicates poor prognosis of colorectal cancer, and may be used as a predictive marker.
