Objective To study the growth suppressive effect of demethylation drug 5-aza-2'-deoxycytidine on bladder tumor cells. Methods The growth suppressive effect of DAC on 4 transitional cell carcinoma (TCC) cell lines was measured using the Cell Proliferation Reagent WST-1 assay.The effects of DAC on apoptosis induction and cell cycle arrest were analyzed by flow cytometric analysis. Caspase 3, 9 activities were analyzed by APOPCYTO Caspase Colorimetric Assay Kit and PCNA expression was also investigated by Western blot to clarify the mechanism of DAC against TCC. Results DAC inhibited the growth of all TCC cell lines tested in a dose-dependant manner, however,growth suppressive effect of DAC was independent of p53 status in TCC. DAC inhibited proliferation via inducing G2/M cell cycle arrest but not via inducing apoptosis. After treated with 0, 1 and 8 μmol/L DAC, cells of RTl 12 in G2/M phase was (36.3 ± 3.4) %, (46.2 ± 4.6) % and (56.5 ±6.2) %, TCCsup was (37.5 ± 3.8) %, (48.4 ±4.9) % and (60.1 ± 6.7) %, respectively. The expression of PCNA was decreased by DAC, but caspase3, 9 activities were not activated. Conclusion DAC could suppress the growth of TCC cells and might be a new strategy to treat bladder malignancy in the future.

Symptomatic venous thromboembolism (VTE) has a six-to seven-fold risk of occurring in cancer patients compared with non-cancer patients. VTE is the second most common cause of death among patients with cancer, and cancer-associated VTE is be-coming increasingly prevalent. Therefore, early diagnosis and treatment of cancer-associated VTE is particularly important. This study presents a pancreatic cancer-associated deep vein thrombosis (DVT) patient who engaged in a multidisciplinary comprehensive discus-sion in the Interventional Therapy Department, Tianjin Medical University Cancer Hospital to enhance concern, interdisciplinary com-munication, and cooperation in terms of cancer-associated VTE diagnosis and treatment strategies.

Objective:To investigate the status quo of pain management for cancer patients in hospice care wards of community health service centers.Methods:The electronic medical records of 373 cancer patients admitted in hospice wards of Kangjian Community Health Center of Xuhui District and Jinshanwei Town Community Health Center of Jinshan District from January 2015 to July 2021 were collected. The characteristics of cancer pain, the use of analgesic drugs, the effects of analgesic drugs and its influencing factors were analyzed.Results:The incidence of cancer pain in 373 patients was 93.0% (347/373), and the proportion of moderate to severe cancer pain was 55.6% (193/347). Analgesics were used in 304 patients, among whom 233 (76.6%) patients used oral analgesics, 297 (97.7%) used on time, 97.6%(285/292) used sustained-release opioids, and 94 (30.9%) used combinedly. Breakout pain occurred in 100 cases (32.9%), all of which was controlled with immediate-release morphine. Cancer pain was not relieved in 132 cases (43.42%), and multivariate logistic regression analysis showed that the pain degree on admission (moderate: OR=3.69, 95 %CI:2.09-6.49; severe: OR=5.52, 95 %CI:2.43-12.53), the presence of burst pain ( OR=3.28, 95 %CI:1.77-6.06), the type of analgesics used (non-steroidal+weak opioids: OR=0.39, 95 %CI:0.20-0.76; nonsteroidal+strong opioids: OR=0.20, 95 %CI:0.08-0.51) and the adverse reactions ( OR=1.92, 95 %CI:1.03-3.60) were the influencing factors of pain relief in cancer pain patients (all P<0.05). Conclusion:The pain of cancer patients admitted to community palliative care wards cannot be ignored. Although most cancer pain patients use analgesic drugs in a standard way, there are still a high proportion of patients whose pain is not controlled. Various factors affect the effect of analgesic treatment.

OBJECTIVEFindings from the previous studies have suggested a relationship between ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP-1) or plasma cell membrane glycoprotein 1 (PC-1) gene single nucleotide polymorphism (K121Q, rs1044498) and genetic susceptibility to obesity. However, such relationship is not reproduced by some currently available studies. In this context, the present study is aimed to quantitatively analyze the association of K121Q variant with obesity in all published case-control studies in European adult populations.
METHODSPublished literature from PubMed, EMBASE, and ISI web of science databases were retrieved. The studies evaluating the association of ENPP1/PC1 gene K121Q polymorphism with obesity were included, in which sufficient data were presented to calculate the odds ratio (OR) with 95% confidence intervals (CIs).
RESULTSTen case-control studies meeting the inclusion criteria identified a total of 24,324 subjects including 11,372 obese and 12,952 control subjects. The meta-analysis results showed a statistically significant association of K121Q with obesity [OR (95%CI): 1.25 (1.04-1.52) P=0.021] under a recessive model of inheritance (QQ vs. KK+KQ) without heterogeneity or publication bias.
CONCLUSIONSThe results from the present study have indicated that ENPP1/PC1 Q121 variant may increase the risk of obesity and that more well-designed studies based on a larger population will be required to further evaluate the role of ENPP1/PC1 gene K121Q polymorphism in obesity and other related metabolic syndromes.
