1.Advances in research on population-based female breast cancer survival in China
Chinese Journal of Clinical Oncology 2016;43(14):639-642
Breast cancer is the most common type of cancer among women in China and around the world. Population-based survival analysis can reflect the overall level of cancer prevention, diagnosis, and treatment in countries or regions, providing basic information for making efficient health policies. Breast cancer survival varies among countries or regions because of differences among races, so-cioeconomic factors, healthcare services, and cancer diagnosis and treatment. Breast cancer prognosis is closely related to tumor stage, status of receptors, and treatments. By determining the relationship between breast cancer survival and related factors, the re-sults can help in predicting the prognosis and evaluating the quality of care services. The article provides an overview of breast cancer survival in China and abroad, as well as references for cancer surveillance.

Objective:Population-based cancer registration data were used to analyze stomach cancer epidemiology in China. Meth-ods:Stomach cancer data were retrieved from the National Central Cancer Registry Database, and incident and death cases were esti-mated. The trend of stomach cancer was analyzed. Results:Approximately 424,000 new cancer cases and 298,000 cancer deaths oc-curred in China in 2012. The incidence and mortality rates of stomach cancer in urban males and females remained stable in 2000-2012, whereas the rates in rural males increased and less changes were observed in rural females. After age standardization, both inci-dence and mortality rates significantly decreased. The five-year age-standardized relative survival rate was 27.4% (95%CI: 26.7%-18.1%) in 2003-2005. Conclusion:Stomach cancer is a common cancer, which has heavy burden in China, particularly in rural areas. Ef-forts should be exerted for the prevention and control of the disease.

Objective:To explore the effect of different tidal volumes (VT) on the hemodynamics of right heart in acute respiratory distress syndrome (ARDS) rats induced by oleic acid (OA).Methods:Sixty adult male Sprague-Dawley (SD) rats were divided into control group ( n = 20), ARDS model group ( n = 20), low VT (LVT) group ( n = 10) and high VT (HVT) group ( n = 10) by random number table. ARDS model was reproduced by injecting OA 0.15 mL/kg through a jugular vein. The control group was given the same amount of normal saline. The success of modeling was judged by the oxygenation index (PaO 2/FiO 2) 2 hours after modeling, at the same time, the lung tissues were collected, the wet/dry weight (W/D) ratio was determined, and the lung histopathological changes were measured by lung injury score. The rats in the LVT group and HVT group were given mechanical ventilation with VT of 6 mL/kg or 20 mL/kg for 4 hours, respectively at 2 hours after modeling. The rats in the control group and the ARDS model group maintained spontaneous breathing. After mechanical ventilation for 4 hours, the heart rate (HR), right ventricular systolic pressure (RVSP), the maximum rate of rising of right ventricular pressure (dp/dt max), and the blood pressure (BP) were measured. Meanwhile, arterial blood samples were collected for blood gas analysis, including pH value, arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2) and PaO 2/FiO 2. Results:The rats in the ARDS model group showed symptoms of respiratory distress 1 hour after modeling, and the lung tissue samples showed obvious patchy bleeding 2 hours after modeling, while the control group showed no such changes. The PaO 2/FiO 2 in the ARDS model group was significantly lower than that in the control group [mmHg (1 mmHg = 0.133 kPa): 294.3±5.9 vs. 459.0±4.4, P < 0.01], and the lung W/D ratio and lung injury score were significantly higher (lung W/D ratio: 8.24±0.25 vs. 4.48±0.13, lung injury score: 0.60±0.03 vs. 0.12±0.02, both P < 0.01). It indicated that ARDS model was successfully reproduced. The arterial blood gas analysis and hemodynamic parameters of the ARDS model group were significantly worse than those of the control group. After 4-hour mechanical ventilation, the blood gas parameters of the LVT group were better than those of the ARDS model group and the HVT group [pH value: 7.36±0.02 vs. 7.24±0.02, 7.13±0.01; PaO 2 (mmHg): 92.4±2.1 vs. 61.8±2.3, 76.6±2.2; PaCO 2 (mmHg): 49.6±1.7 vs. 61.8±1.8, 33.6±1.3; PaO 2/FiO 2 (mmHg): 440.0±10.2 vs. 274.3±21.4, 364.7±10.5; all P < 0.05]. HR, BP and dp/dt max in the LVT group were significantly higher than those in the ARDS model group and the HVT group [HR (bpm): 346.9±5.4 vs. 302.3±10.1, 265.5±12.2; BP (mmHg): 125.4±2.2 vs. 110.0±2.5, 89.2±2.8; dp/dt max (mmHg/s): 1 393.3±30.3 vs. 1 236.4±20.5, 896.1±19.5; all P < 0.05], and RVSP was significantly lower than that in the ARDS model group and the HVT group (mmHg: 31.3±0.4 vs. 34.0±1.0, 38.8±0.9, both P < 0.05). Conclusion:Mechanical ventilation with low VT can improve the hemodynamic parameters of the right ventricle and protect the function of the right heart in ARDS rats.

Objective:To investigate whether myocardial inflammation and apoptosis are involved in right ventricular dysfunction (RVD) induced by injurious mechanical ventilation with high tidal volume (VT) in rats.Methods:Total 30 adult male SD rats were randomly divided into the control group (CON group), the low VT ventilation group (LVT group) and the injurious mechanical ventilation group (HVT group), with 10 rats in each group. The CON group was maintained spontaneous breathing, the LVT group and HVT group were ventilated with different VT 6 mL/kg and 20 mL/kg for 4 hours, respectively. The right jugular vein and the left carotid artery were catheterized and connected with the PowerLab biological signal acquisition and analysis system to record heart rate (HR), mean arterial pressure (MAP), right ventricular systolic pressure (RVSP), the maximum rate of rising of right ventricular pressure (+dp/dt max). Echocardiography was performed to measure left ventricular end-diastolic diameter (LVEDd), right ventricular end-diastolic diameter (RVEDd), tricuspid annulus plane systolic migration (TAPSE) and myocardial performance index (MPI). The rats were sacrified by cervical dislocation. Specimens of right ventricle tissues were taken for hematoxylin-eosin (HE) staining, and morphological changes of right ventricle tissues were observed under light microscope. Real time reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting were used to detect the mRNA and protein expressions of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), caspase-3, apoptosis-related proteins Bax and Bcl-2.Results:HR, MAP, +dp/dt max gradually decreased, while RVSP gradually increased in different group with the increase of VT ventilation. There was no significant difference between the CON group and LVT group. However, there was a statistically significant difference with respect to these index in HVT group as compared to CON group and LVT group [HR (bpm): 397.6±5.7 vs. 433.0±4.8, 441.6±7.8; MAP (mmHg, 1 mmHg≈0.133 kPa): 102.0±2.4 vs. 108.5±2.2, 110.6±2.1; +dp/dt max (mmHg/s): 2 357.65±62.80 vs. 2 661.27±55.62, 2 679.43±75.13; RVSP (mmHg): 28.8±1.0 vs. 22.6±10.8, 21.9±0.4; all P < 0.05]. Echocardiography findings showed that RVEDd/LVEDd and MPI gradually increased, TAPSE gradually decreased in different group with the increase of VT ventilation. There was no significant difference between the LVT group and CON group. However, there was a statistically significant difference with respect to these indexes in HVT group as compared to the CON group and LVT group [RVEDd/LVEDd: 0.36±0.02 vs. 0.26±0.01, 0.23±0.02; MPI: 1.23±0.03 vs. 0.84±0.04, 0.86±0.03; TAPSE (mm): 1.65±0.03 vs. 1.88±0.02, 1.91±0.04; all P < 0.05]. Histopathological observation of the right ventricle tissue showed that myocardial cells of the rats in the CON group were orderly arranged and uniformed in size. In the LVT group, there was a small amount of inflammatory cell infiltration in the myocardial interstitium, while in the HVT group, the myocardial cell arrangement was obviously disordered, the structure was obviously damaged, and more inflammatory cell infiltration was found. RT-PCR and Western blotting analysis showed that the mRNA and protein expressions of IL-6, TNF-α, caspase-3 and Bax in HVT group were significantly higher than those in the LVT group and CON group [mRNA expression (2 -ΔΔCt): IL-6 were 1.97±0.07 vs. 1.09±0.02, 1.02±0.03, TNF-α were 1.69±0.10 vs. 1.10±0.03, 1.05±0.04, caspase-3 were 1.82±0.09 vs. 1.08±0.02, 1.06±0.03, Bax were 2.19±0.14 vs. 1.07±0.03, 1.04±0.03; protein expression (gray value): IL-6 were 0.64±0.02 vs. 0.38±0.03, 0.31±0.04, TNF-α were 0.50±0.04 vs. 0.16±0.01, 0.15±0.01, caspase-3 were 0.58±0.02 vs. 0.29±0.01, 0.25±0.02, Bax were 0.50±0.03 vs. 0.21±0.01, 0.26±0.02; all P < 0.05], and the mRNA and protein expressions of Bcl-2 in the HVT group were lower than those in the LVT group and CON group [mRNA expression (2 -ΔΔCt): 1.23±0.05 vs. 1.43±0.05, 1.50±0.08; protein expression (gray value): 0.42±0.02 vs. 0.62±0.03, 0.65±0.03, all P < 0.05]. Conclusion:Myocardial inflammation and apoptosis may be involved in RVD induced by injurious mechanical ventilation.

Objective The national population?based cancer registration data were used to analyze the liver cancer incidence and trend in China,in order to provide advise for making further strategy on liver cancer prevention and control. Methods Liver cancer data of 2011 were retrieved from the database of the National Cancer Registry. The incident cases of liver cancer were estimated using age?specific rate by urban or rural areas and gender according to the national population in 2011. Liver cancer incidence data from 22 cancer registries were used to analyze the incidence trend during 2000?2011. Results The estimates of new cases of liver cancer were about 356 thousand in China in 2011. The incidence rate was 26.39/105 , and the age?standardized incidence rates by Chinese standard population and by world population were 19.48/105 and 19.10/105, respectively.There was an increasing trend of incidence rate of liver cancer in China during 2000?2011 with an average annual percentage change(AAPC) of 1.0%(95%CI:0.5%?1.4%), 1.2%(95%CI:0.7%?1.8%)in urban areas and 1.1%(95%CI:0.5%?1.8%) in rural areas. After age standardization, the incidence rate was significantly decreased, with an AAPC of -1. 8%( 95%CI:-2. 4% to -1. 2%) ,-1. 6%(95%CI: -2.2% to -0.9%)in urban and -1.4% (95%CI:-2.5% to -0.3%)in rural areas. Conclusions Liver cancer is a common cancer in China. As changing in people′s dietary habits and implementing neonatal HBV vaccination for years, the exposure to risk factors is reducing, and age?standardized incidence rate is decreasing. While cardinal number of population is big and aging population is growing rapidly in the country, trend of incidence rate is increasing,and the burden of liver cancer is still high in China.
