Yueling Hu, Yun Li, Wenrui Wang, Yonggang Qian, Chunxia Hui, Kepeng Xin, Shiqi Wang, Juan Sun
Open Journal of Epidemiology (OJEpi) , 2014, DOI: 10.4236/ojepi.2014.43019
Abstract:

Background: The aim of this study was to explore the characteristics of breast cancer mortality in Inner Mongolia, and to provide evidence for the prevention of female breast cancer. Methods: Using data from the Death Registry System from 2008 to 2010. We classified female cancer deaths according to the International Classification of Disease-10th Revision. The mortality of different age groups and the potential years of life lost were calculated for female breast cancer in Inner Mongolia. Results: Breast cancer mortality for Inner Mongolian women was higher in older age groups. The potential years of life lost were also much higher in younger groups than in older groups. Marital status, education level and occupation may contribute to this increase in breast cancer mortality in younger groups. Conclusion: Preventive policies should be implemented to de- velop strategies aimed at reducing the breast cancer mortality, especially with regard to younger age groups in Inner Mongolia.

Pharmacology & Pharmacy (PP) , 2015, DOI: 10.4236/pp.2015.611052
Abstract: To examine the cytocidal effect of sodium nitrite on the cancer cell, we subjected human gastric adenocarcinoma epithelia (AGS) cells to various experimentation following exposure to sodium nitrite, and measured the resulting changes in the levels of cell death, lactate dehydrogenase (LDH) release, and caspase-3, -6, -8, and -9 activities. Our data revealed that, in AGS cells, treatment with ≥6.25 mM sodium nitrite for 8 h resulted in an obvious increase in cell death. LDH release was also markedly increased following sodium nitrite treatment, but at a concentration of ≥6.25 mM for 24 h. This increasing trend showed a positive correlation (r = 0.9564, P < 0.05). In addition, we detected pronounced increases in caspase activities with various concentrations of sodium nitrite: caspase-3 at ≥25 mM for 1 h, ≥12.5 mM for 3 h and 6 h; caspase-9 at 50 mM for 1 h and 3 h, and ≥6.25 mM for 6 h; and caspase-6 at 50 mM for 1 h and 3 h. We did not however, detect any observable increase in the activity of caspase-8 following sodium nitrite treatment at any concentration or for any duration of treatment in this study. This data demonstrates that, in AGS cells, higher concentrations or longer durations of treatment with sodium nitrite could exhibit a cytocidal effect, and that sodium nitrite could induce apoptosis via activation of the caspase-9, caspase-3 cascade (intrinsic pathway) and caspase-6.

Open Journal of Epidemiology (OJEpi) , 2016, DOI: 10.4236/ojepi.2016.62014
Abstract: Objective: The purpose of this study was to evaluate the difference in alcohol use between urban and rural students of Inner Mongolia Medical University. Methods: A cross-sectional census was conducted on medical students on campus in 2013. We use multivariate logistic regression models to assess the factors associated with alcohol use. We further use chi-square test assess on differences in alcohol use between urban and rural people among significance factors in logistic regression models. Results: The prevalence of alcohol use among students in rural area was higher than that in urban area (p = 0.016). Alcohol use was associated with Gender, monthly expenses, residence, ethnic and faculty. The odds of alcohol use for Mongolia students were 1.139 times higher than that for Han students. The prevalence of alcohol consumption among students from pharmacy or Traditional Chinese Medicine and Mongolian Medicine faculties in rural area was higher than that among student in urban area (p = 0.03; p = 0.001). The prevalence of alcohol use among female students in rural area was higher than that among female students in urban area (p < 0.043). The proportion of alcohol use among students with <600 in rural area was higher than that among students in urban area (p < 0.001). Conclusion: Considering the differences in the prevalence of alcohol use between rural area and urban area, university administrators aiming at students from various regions develop various approaches.
Constraints on hard spectator scattering and annihilation corrections in $B_{u,d}$ ${\to}$ $PV$ decays within QCD factorization
Junfeng Sun,Qin Chang,Xiaohui Hu,Yueling Yang
Physics , 2014, DOI: 10.1016/j.physletb.2015.03.001
Abstract: In this paper, we investigate the contributions of hard spectator scattering and annihilation in $B\to PV$ decays within the QCD factorization framework. With available experimental data on $B\to \pi K^{\ast}$, $\rho K$, $\pi \rho$ and $K\phi$ decays, comprehensive $\chi^2$ analyses of the parameters $X_{A,H}^{i,f}({\rho}_{A,H}^{i,f},{\phi}_{A,H}^{i,f})$ are performed, where $X_A^f$ ($X_A^i$) and $X_H$ are used to parameterize the endpoint divergences of the (non)factorizable annihilation and hard spectator scattering amplitudes, respectively. Based on $\chi^2$ analyses, it is observed that (1) The topology-dependent parameterization scheme is feasible for $B\to PV$ decays; (2) At the current accuracy of experimental measurements and theoretical evaluations, $X_H=X_A^i$ is allowed by $B\to PV$ decays, but $X_{H}\neq X_A^f$ at $68%$ C. L.; (3) With the simplification $X_H=X_A^i$, parameters $X_A^f$ and $X_A^i$ should be treated individually. The above-described findings are very similar to those obtained from $B\to PP$ decays. Numerically, for $B\to PV$ decays, we obtain $(\rho_{A,H}^i,\phi_{A,H}^i[^{\circ}]) =(2.87^{+0.66}_{-1.95}, -145^{+14}_{-21})$ and $(\rho_A^f,\phi_A^f[^{\circ}]) = (0.91^{+0.12}_{-0.13}, -37^{+10}_{-9})$ at $68%$ C. L.. With the best-fit values, most of the theoretical results are in good agreement with the experimental data within errors. However, significant corrections to the color-suppressed tree amplitude $\alpha_2$ related to a large $\rho_H$ result in the wrong sign for $A^{dir}_{CP}(B^- \to \pi^0 K^{{\ast}-})$ compared with the most recent BABAR data, which presents a new obstacle in solving "$\pi\pi$" and "$\pi K$" puzzles through $\alpha_2$. A crosscheck with measurements at Belle (or Belle II) and LHCb, which offer higher precision, is urgently expected to confirm or refute such possible mismatch.

Open Journal of Epidemiology (OJEpi) , 2017, DOI: 10.4236/ojepi.2017.71002
Abstract: Objective: The aim of our study was to analyze the character of cause of death in Inner Mongolia of China from 2008 to 2014. Methods: We collected data from monitoring points of the Death Registry System (DRS) in Inner Mongolia. We calculated the mortality rates by gender, year and age-specific. We calculated the proportion, the mortality rate and potential years of life lost (PYLL) of various system deaths. Results: During the period 2008-2014, the average crude mortality rate of all cause of death was 539.33/105. The mortality rate increased semilogarithm linearly with age. The top four system deaths were circulatory system, neoplasm, respiratory system and injury. In 2014, the mortality rates of circulatory system were increased and the mortality rates of certain infectious and parasitic diseases, neoplasms, respiratory system, genitourinary system and injury were decreased compared to those in 2008. Conclusion: Through analysis the indicators of proportion, the mortality rate and PYLL indicated that health status of a population in Inner Mongolia was at a better level.

Open Journal of Epidemiology (OJEpi) , 2017, DOI: 10.4236/ojepi.2017.72012
Abstract: Objective: The study aimed to assess the characteristics of pancreatic cancer deaths and the relationship between socio-demographic status and mortality risk of pancreatic cancer in Inner Mongolia. Method: We obtained our data for 2008-2014 from the Death Registry System of Inner Mongolia. We calculated the mortality rate, potential years of life lost (PYLL) and average years of life lost (AYLL) for men and women. We collected socio-demographic characteristics including education level, ethnicity, region, and occupation. Logistic regression models were employed to analyze risk factors of pancreatic cancer. Results: The average mortality rate of pancreatic cancer was 4.42/100,000 in Inner Mongolia during 2008 to 2014. Mortality rate in men was higher in all age groups compared with those in women. The highest mortality rate was 1.3 times than the lowest mortality rate for men and 1.6 times for women during seven years. Average AYLL in women were more than 3.4 years compared with that in men. PYLLR in women was fluctuated from 0.41 to 0.63 per thousand during 2008 to 2014. In eastern region, no occupation and high education level had a higher risk of pancreatic cancer. Conclusion: In Inner Mongolia, the mortality rate associated with pancreatic cancer was higher in men compared with in women. More than 65 years old groups had high death risk for pancreatic cancer. Average years of life lost for women were significantly higher than that for men. We should pay more attention to the older men.

环境科学学报(英文版) , 2009,
Abstract: A bacterial strain BAP5 with a relatively high degradation ability of benzoa]pyrene (BaP) was isolated from marine sediments of Xiamen Western Sea, China and identified as Ochrobactrum sp. according to 16S rRNA gene sequence as well as Biolog microbial identification system. Strain BAP5 could grow in mineral salt medium with 50 mg/L of BaP and degrade about 20% BaP after 30 d of incubation. Ochrobactrum sp. BAP5 was able to utilize other polycyclic aromatic hydrocarbons (PAHs) (such as phenanthrene, pyrene and fluoranthene) as the sole carbon source and energy source, suggesting its potential application in PAHs bioremediation. The profile of total soluble protein from Ochrobactrum sp. BAP5 was also investigated. Some over- and special-expressed proteins of strain BAP5 when incubated with the presence of BaP were detected by two-dimensional polyacrylamide gel electrophoresis, and found to be related with PAHs metabolism, DNA translation, and energy production based on peptide fingerprint analysis through matrix-assisted laser desorption/ionization-time of flight mass spectrometry.

Journal of Tuberculosis Research (JTR) , 2015, DOI: 10.4236/jtr.2015.31002
Abstract: Background: It is very important to enhance the therapeutic effect and prognosis of severe tuberculous hemoptysis after the determining of its etiological cause and the source of bleeding. The etiology and integrated curative effect of severe hemoptysis due to pulmonary tuberculosis among 112 inpatients were analyzed. Materials and Methods: The cause was retrospectively analysed. The integrated management effect after the follow-up of mean three years in 112 cases with severe hemoptysis being resulted from pulmonary tuberculosis from June 2008 to July 2012 was described. Active pulmonary tuberculosis ranked the first cause of lower respiratory tract bleeding (32/112, 28.5%), followed by old pulmonary tuberculosis (28/112, 25.0%), tuberculous bronchiectasis (25/112, 22.3%), purified tuberculous cavity (12/112, 10.7%), fungal infection in old pulmonary tuberculosis cavity (9/112, 7.1%), or broncholithiasis (6/112, 5.4%). Almost all suffers with severe hemoptysis were treated by an integrated management, including psychology, anticoagulants, vasoconstrictor agents. Etiological treatment including anti-tuberculosis and anti-infection was simultaneously or subsequently involved. Sixty-four inpatients with severe hemoptysis being failed to be cured by medical treatment were then received selective bronchial artery embolization. Four patients were received surgical wedge resection, lobectomy or pneumonectomy. The total cure rate added up to 98.2% after mean three years’ follow-up. The mortality was 1.8%. Conclusions: Active pulmonary tuberculosis was still responsible for the severe hemoptysis in the southeast region of China. Severe hemoptysis of pulmonary tuberculosis was also resulted from stable tuberculosis, tuberculous bronchiectasis, tuberculosis cavity, fungal infection, or broncholithiasis. Better clinical therapeutic effect could be attained by early etiological diagnosis and comprehensive treatment strategy.

Journal of Biosciences and Medicines (JBM) , 2017, DOI: 10.4236/jbm.2017.512005
Abstract:
Ductal breast cancer is a clinically heterogeneous disease; we investigate the correlation between tumor size, comedo necrosis, number of cell mitoses and axillary lymph node metastasis in ductal breast cancer. In this study, 104 ductal breast cancer specimens were collected and divided into 3 groups: T1 group (tumor size ≤ 2 cm), T2 group (2 < tumor size ≤ 5 cm) and T3 group (tumor size > 5.0 cm). Among those specimens, 95 cases were diagnosed with invasive ducted carcinoma, and 9 cases were ductal carcinoma in-situ (DCIS). Results show that T3 group has a higher rate of axillary lymph node metastasis than T2 group and T1 group; T2 group has a higher rate of lymph node metastasis than T1 group. The patients with the number of cell mitoses (≥10) were also has a higher rate of axillary lymph node metastasis (P = 0.0139) than the patients with the number of cell mitoses (<10). No significance was found between comedo necrosis lesions and axillary lymph node metastasis, though the frequency of comedo necrosis lesions in patients with axillary lymph node metastasis was higher than those in non-metastatic patients. It is concluded that the tumor size and the number of cell mitoses were risk factors for axillary lymph node involvement in ductal breast cancer.
