Nasopharyngeal carcinoma (NPC) is an uncommon disease in most countries but occurs with much greater frequency in southern China. This study aimed to examine the secular trends of NPC in urban Guangzhou over the time period of 2000-2011 using data from the Guangzhou Cancer Registry. Age-adjusted annual incidence rates of NPC were calculated by the direct method using the WHO World Standard Population (1960) as the reference. The average annual percentage change (AAPC) was used as an estimate of the trend. A total of 7,532 new cases of NPC and 3,449 related deaths were registered. In both genders, the peak incidence occurred in the 50- to 59-year age group, and this age distribution pattern remained similar throughout. The AAPC in NPC incidence rates was -3.26% (95% CI: -5.4%--1.1) for males and -5.74% (95% CI: -8.9%--2.5) for females, resulting in a total decrease of 39.3% (from 22.14 to 13.44 per 100,000 population) for males and 48.6% (from 10.1 to 5.18 per 100,000 population) for females over this 12-year period. The AAPCs in NPC mortality rates were -4.62% (95%CI: -3.5%--5.7) for males and -6.75% (95% CI: -5.2%--8.3) for females, resulting in a total decrease of -46.1% (from 12.1 to 6.54 per 100,000 population) for males and 51.7% (from 4.14 to 2.00 per 100,000 population) for females. The age-adjusted incidence and mortality rates of NPC declined during 2000-2011 in urban Guangzhou but remained high. Future efforts to improve prevention, early detection and treatment strategies are needed.

Background: Curdione, one of the major components of Curcuma zedoaria, has been reported to possess various biological activities. It thus might be a candidate anti-flammatory and cancer chemopreventive agent. However, the precise molecular mechanisms of action of curdione on cancer cells are still unclear. In this study, we investigated the effect of curdione on breast cancer. Materials and Methods: Xenograft nude mice were used to detect the effect of curdione on breast cancer in vivo; we also tested the effect of curdione on breast cancer in vitro by MTT, Flow cytometry, JC-I assay, and western blot. Results: Firstly, we found that curdione significantly suppressed tumor growth in a xenograft nude mouse breast tumor model in a dose-dependent manner. In addition, curdione treatment inhibited cell proliferation and induced cell apoptosis. Moreover, after curdione treatment, increase of impaired mitochondrial membrane potential occurred in a concentration dependent manner. Furthermore, the expression of apoptosis-related proteins including cleaved caspase-3, caspase-9 and Bax was increased in curdione treatment groups, while the expression of the anti-apoptotic Bcl-2 was decreased. Inhibitors of caspase-3 were used to confirm that curdione induced apoptosis. Conclusions: Overall, our observations first suggested that curdione inhibited the proliferation of breast cancer cells by inducing apoptosis. These results might provide some molecular basis for the anti-cancer activity of curdione.

Previous studies have shown that miR-454 plays an important role in a variety of biological processes in various human cancer cells. However, the underlying mechanisms of this microRNA in colorectal cancer (CRC) cells remain largely unknown. In the present study, we investigated the miR-454 role in CRC cell proliferation. We found that miR-454 expression is markedly upregulated in CRC tissues and CRC cells compared with the matched tumor adjacent tissues and the FHC normal colonic cell line. Ectopic expression of miR-454 promoted the proliferation and anchorage-independent growth of CRC cells, whereas inhibition of miR-454 reduced this effect. Bioinformatics analysis further revealed cylindromatosis (CYLD), a putative tumor suppressor as a potential target of miR-454. Data from luciferase reporter assays showed that miR-454 directly binds to the 3'-untranslated region (3'-UTR) of CYLD mRNA and repressed expression at both transcriptional and translational levels. In functional assays, CYLD-silenced in miR-454-in-transfected SW480 cells have positive effect to promote cell proliferation, suggesting that direct CYLD downregulation is required for miR-454-induced CRC cell proliferation. In sum, our data provide compelling evidence that miR-454 functions as an onco-miRNA, playing a crucial role in the promoting cell proliferation in CRC, and its oncogenic effect is mediated chiefly through direct suppression of CYLD expression.

Background: Liver cirrhosis causes substantial socio-economic burden and is one of the major severe liver diseases in Korea. Nonetheless, there is only a few studies that analyzes disease burden of liver cirrhosis in Korea. Such study must be carried out due to its increasing need from the invention of new drugs for chronic hepatitis and demand for cost-effectiveness analyses. Methods: Patient sample data with ensured representativeness was analyzed retrospectively to compare the medical costs and uses for patients with compensated cirrhosis and decompensated cirrhosis. Patient claims data that include K74 and K703 from the year of 2014 were selected. Within the selected data, decompensated cirrhosis patient was identified if complications such as ascites (R18), encephalopathy (B190), hepatic failure (K72), peritonitis (K65), or esophageal varices (I85) were included, and they were compared to compensated cirrhosis patients. Results: 6,565 patients were included in the analysis. The average cost per patient was 6,471,020 (SD 8,848,899) KRW and 2,173,203 (4,220,942) KRW for decompensated cirrhosis and compensated cirrhosis, respectively. For inpatients, the average hospitalized days was 38.0 (56.4) days and 27.2 (57.2) days for decompensated cirrhosis and compensated cirrhosis, respectively. For outpatients, the average number of visits was 8.7 (9.1) days and 5.3 (7.5) days for compensated cirrhosis and decompensated cirrhosis, respectively. Conclusion: Compared to compensated cirrhosis patients, decompensated cirrhosis patients had higher costs, especially for hospitalization, injection, examination, and drugs administrated within medical institutions.

The purpose of this study was to determine the effects of duration and timing of glucocorticoid treatment on the expansion and differentiation of porcine neonatal pancreas cell clusters (NPCCs) into ${\beta}$-cells. After transplantation of NPCCs, the ductal cyst area and ${\beta}$-cell mass in the grafts both showed positive and negative correlations with duration of dexamethasone (Dx) treatment. Pdx-1 and HNF-3${\beta}$ gene expression was significantly downregulated following Dx treatment, whereas PGC-1${\alpha}$ expression increased. Pancreatic duct cell apoptosis significantly increased following Dx treatment, whereas proliferation did not change. Altogether, transdifferentiation of porcine NPCCs into ${\beta}$-cells was influenced by the duration of Dx treatment, which might have been due to the suppression of key pancreatic transcription factors. PGC-1${\alpha}$ plays an important role in the expansion and transdifferentiation of porcine NPCCs, and the initial 2 weeks following transplantation of porcine NPCCs is a critical period in determining the final ${\beta}$-cell mass in grafts.

Objective: To assess the safety of Brucea javanica and Cantharidin combined with chemotherapy in treating patients with non-small-cell lung carcinoma. Method: A consecutive cohort of patients with NSCLC were divided into four groups: experimental group A treated with Brucea javanica injection combined with chemotherapy; experimental group B with Cantharidin injection combined with chemotherapy; experimental group C treated with Brucea javanica and Cantharidin injection combined with chemotherapy; and the control group receiving only chemotherapy. After more than two courses of treatment, safety, quality of life and side effects were evaluated. Results: The incidences of myelosuppression in groups A, B and C were lower than that in Control group (p<0.05), but without significant differences among A, B and C. Adverse effects on the gastrointestinal tract also were lower than in controls (p<0.05) without variation amnog the combined treatment groups. Conclusions: Brucea javanica or Cantharidin combined with chemotherapy could in both cases improve quality of life in our cohort of NSCLC patients without any increase in toxicity. However, further clinical experiments should be conducted to evaluate the efficacy of Brucea javanica and Cantharidin combined with chemotherapy for patients with NSCLC.

The effect of human MutY homolog (hMYH) on the activation of checkpoint proteins in response to hydroxyurea (HU) and ultraviolet (UV) treatment was investigated in hMYH-disrupted HEK293 cells. hMYH-disrupted cells decreased the phosphorylation of Chk1 upon HU or UV treatment and increased the phosphorylation of Cdk2 and the amount of Cdc25A, but not Cdc25C. In siMYH-transfected cells, the increased rate of phosphorylated Chk1 upon HU or UV treatment was lower than that in siGFP-transfected cells, meaning that hMYH was involved in the activation mechanism of Chk1 upon DNA damage. The phosphorylation of ataxia telangiectasia and Rad3-related protein (ATR) upon HU or UV treatment was decreased in hMYH-disrupted HEK293 and HaCaT cells. Co-immunoprecipitation experiments showed that hMYH was immunoprecipitated by anti-ATR. These results suggest that hMYH may interact with ATR and function as a mediator of Chk1 phosphorylation in response to DNA damage.
