Melanoma is the most aggressive and lethal malignant tumor in skin cancers. Operation resection is used to treat stageⅠ/Ⅱmelanomas, but traditional operation, chemotherapy, and radiotherapy inflicts adverse effects on late-stage melanomas. StageⅢ/Ⅳmelanomas are some of the most ineffectively treated tumors with poor prognosis. As a cancer treatment, targeted immunotherapy in-hibits negative regulatory factors and enhances systemic anti-tumor immune effects. Radiotherapy not only kills tumor cells, but also en-hances systemic immune responses. Recent studies showed that targeted immunotherapy combined with radiotherapy can promote con-trol on local and distant tumors and prolong overall survival. The synergistic effects of these two therapies are superior to a single thera-py. This review summarized the progress on these research fields.

[Summary] Radical prostatectomy, external beam radiation and active surveillance are the main treatments for localized prostate cancer. However, many patients are difficult to accept the psychological burden of active surveillance and the distress caused by potential side effects of radical therapy, including incontinence and erectile dysfunction, which make them limited. With the development of minimally invasive techniques, such as brachytherapy, cryoablation, high-intensity focused ultrasound, photodynamic therapy, and irreversible electroporation, novel procedures are playing an increasingly important role in the treatment of localized prostate cancer with their effective, minimally invasive, and safe advantages. This article mainly reviewed the above several minimally invasive treatment methods.

Objective To investigate the relationship between matrix metalloproteinase-3 (MMP-3) gene promoter polymorphisms 5A/6A and the restenosis after percutaneous coronary intervention (PCI). Methods A total of 437 patients with PCI were selected in this study. Patients were divided into mutant genotype group (5A/5A+5A/6A, n=136) and wild genotype group (6A/6A, n=301) according to MMP-3 polymorphism. The angiography and clinic data were collected before and after coronary angiography in two groups of patients. The serum level MMP-3 and genotype analysis were compared be-tween two groups. Results There was no significant difference in the restenosis rate between two groups (42.2%vs 33.1%, P>0.05). The restenosis degree was significantly higher in wild genotype group than that in mutant genotype group (56.28%± 11.10%vs 36.00%±10.17%, P<0.01). There was no significant difference in the serum level of MMP-3 between two groups (13.38μg/L ± 3.00μg/L vs 12.33μg/L ± 2.96μg/L, P>0.05). There was a higher restenosis rate in patients carrying 6A al-lele than that of patients carrying 5A allele (P<0.05). Carrying wild genotypes are risk factors for restenosis after PCI. Con-clusion Patients carrying 6A allele have significantly higher risk of resteonsis than patients carrying 5A allele.

As an effective procedure for type 1 diabetes mellitus and end-stage type 2 diabetes mellitus, islet transplantation could enable those patients to obtain proper control of blood glucose levels. Instant blood-mediated inflammatory reaction (IBMIR) is a nonspecific inflammation during early stage after islet transplantation. After IBMIR occurs, coagulation cascade, complement system activation and inflammatory cell aggregation may be immediately provoked, leading to loss of a large quantity of transplant islets, which severely affects clinical efficacy of islet transplantation. How to alleviate the islet damage caused by IBMIR is a hot topic in islet transplantation. Heparin and etanercept, an inhibitor of tumor necrosis factor-

Objective To identify the key genes and targeted protection methods affecting the survival of human islets. Methods Using bioinformatics method, the gene expression profile (GSE53454) was selected through screening and comparison from Gene Expression Omnibus(GEO) database. GEO2R tool was employed to screen the differentially expressed gene(DEG) between the human islets exposed (exposure group) and non-exposed (non-exposure group) to interleukin (IL)-1β and interferon (IFN)-γ for 24, 48 and 72 h, respectively. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed by DAVID. Protein-protein interaction (PPI) network was constructed by STRING and Cytoscape apps. Results A total of 69 up-regulated DEGs and 2 down-regulated DEGs were identified. GO analysis showed that during the biological process, DEGs were enriched in the aspects of virus defense and inflammatory response. In cellular components, DEGs were significantly enriched in extracellular space, outside plasma membrane and extracellular regions. Regarding molecular functions, DEGs were significantly enriched in chemokine activity and cytokine activity. KEGG analysis revealed that DEGs were mainly enriched in multiple signaling pathways, such as cytokine-cytokine receptor interaction, virus protein-cytokine and cytokine-receptor interaction,

OBJECTIVE:
To assess the association of 5A/6A polymorphism in the promoter region of MMP3 gene with the stability of extracellular matrix of atherosclerotic plaque.
METHODS:
Clinical data of 776 consecutive patients undergoing percutaneous coronary intervention (PCI) was reviewed. MMP3 gene polymorphisms and serum level of MMP3 for the second admission were collected. The target gene fragment containing MMP3 promoter region was transfected into HepG2 vector cells. The influence of the polymorphism on the expression of the MMP3 gene was determined in vitro.
RESULTS:
Compared with the first admission data, the proportion of mutant MMP3 genotypes (5A/5A+5A/6A) was significantly higher in patients with acute myocardial infarction (AMI) compared with the control group (37.6% vs. 24.9%, P<0.01). 64.1% of the patients carrying the 5A allele had AMI, whereas only 50.11% of those carrying the 6A allele had AMI (P<0.01). The proportion of wild-type MMP3 genotype (6A/6A) was significantly higher in the stenotic group compared with the non-restenosis group (79.5% vs. 66.5%, P<0.01). Restenosis has occurred in 9.5% of patients harboring the 5A allele compared with 16.2% in those carrying the 6A allele (P<0.01). In addition, serum level of MMP3 in the restenosis group was significantly lower than that of the non-restenosis group (P<0.01). In vitro studies confirmed that the expression of pGL2-Basic/6A was significantly lower than that of pGL2-Basic/5A.
CONCLUSION
The 5A/6A polymorphism in the promoter region of the MMP3 gene may influence its transcriptional activity and impact on the degradation or push-up of extracellular matrix, resulting in a difference in the stability of atherosclerosis plaques, which in turn may induce different pathological processes in AMI or restenosis after stenting.
