  • Several lines of evidence suggest that genetic variation in MUC5AC gene might contribute to the risk of gastric cancer. We conducted a case-control study to evaluate the relationship between common genetic variations in MUC5AC gene and non-cardia gastric cancer using an LD-based tagSNP approach in Baotou, north-western China. We genotyped 12 tagSNPs by TaqMan method among 288 cases with non-cardia gastric cancer and 281 normal controls. Unconditional logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for non-cardia gastric cancer risk in association with alleles, genotypes and haplotypes. We observed that the frequencies of rs3793964 C allele and rs11040869 A allele were significantly lower in cases than in controls. Meanwhile, minor allele homozygotes of rs3793964 and rs11040869 were significantly associated with a decreased risk of non-cardia gastric cancer when compared with their major allele homozygotes. Furthermore, a statistically significantly protective effect of rs885454 genotypes on non-cardia gastric cancer was also observed (for CT vs. CC: OR=0.581, 95%CI=0.408-0.829; for CT/TT vs. CC: OR=0.623, 95%CI=0.451-0.884). Our results indicated that some common genetic variations in the MUC5AC gene might have effects on the risk of non-cardia gastric cancer in our studied population.

  • Objective: The research was conducted to determine the digestible (DE) and metabolizable energy (ME) contents as well as the apparent total tract digestibility (ATTD) of nutrients in corn, waxy corn and steam-flaked corn fed to growing pigs. Methods: Eighteen growing pigs with initial body weight of $15.42{\pm}1.41kg$ were randomly allotted to three diets including a corn diet, a waxy corn diet and a steam-flaked corn diet in a completely randomized design. Each treatment contained six replicates. The experiment lasted for 12 days, which comprised 7-d adaptation to diets followed by a 5-d total collection of feces and urine. The energy contents and the nutrient digestibility in three ingredients were calculated using direct method. Results: Compared to normal corn, both the amylose and dietary fiber contents in waxy corn were numerically lower, but the starch gelatinization degree was numerically greater. Moreover, the DE and ME contents as well as the ATTD of neutral detergent fiber and acid detergent fiber (ADF) in waxy corn were significantly greater (p<0.05) than those in normal corn when fed to growing pigs. Furthermore, the steam-flaked corn had greater (p<0.05) DE and ME contents, and ATTD of ether extract and ADF compared to normal corn. Conclusion: Both variety and processing procedure have influence on chemical compositions, energy contents and nutrient digestibility of corn. The waxy corn and steam-flaked corn had greater degree of starch gelatinization and DE and ME contents compared to normal corn when fed to growing pigs.

  • Objective: To evaluate the feasibility, safety, and effectiveness of CT-guided microcoil localization of solitary pulmonary nodules (SPNs) for guiding video-assisted thoracoscopic surgery (VATS). Materials and Methods: Between June 2016 and October 2019, 454 consecutive patients with 501 SPNs who received CT-guided microcoil localization before VATS in our institution were enrolled. The diameter of the nodules was 0.93 ± 0.49 cm, and the shortest distance from the nodules to the pleura was 1.41 ± 0.95 cm. The distal end of the microcoil was placed less than 1 cm away from the nodule, and the proximal end was placed outside the visceral pleura. VATS was performed under the guidance of implanted microcoils without the aid of intraoperative fluoroscopy. Results: All 501 nodules were marked with microcoils. The time required for microcoil localization was 12.8 ± 5.2 minutes. Microcoil localization-related complications occurred in 179 cases (39.4%). None of the complications required treatment. A total of 463 nodules were successfully resected under the guidance of implanted microcoils. VATS revealed 38 patients with dislocated microcoils, of which 28 underwent wedge resection (21 cases under the guidance of the bleeding points of pleural puncture, 7 cases through palpation), 5 underwent direct lobectomy, and the remaining 5 underwent a conversion to thoracotomy. In 4 cases, a portion of the microcoil remained in the lung parenchyma. Conclusion: CT-guided microcoil localization of SPNs is safe and reliable. Marking the nodule and pleura simultaneously with microcoils can effectively guide the resection of SPNs using VATS without the aid of intraoperative fluoroscopy.

  • Concentrations of ambient air particles such as total suspended particulates (TSP), particulate matter $(PM)_{10}$, and $PM_{2.5}$, were monitored simultaneously from May to June, 2007, at four locations at Alashan and Beijing in China, and Seoul and Gosan in South Korea. These monitoring sites are in the pathway of Asian dust (AD) storms traveling from China to the Korean peninsula. An AD event was observed in the Korean peninsula on May 25-26. During the sampling period, the average concentrations of TSP and PM10 were each higher than $150\;{\mu}g/m^3$ in Alashan and Beijing, but not in Seoul and Gosan. The concentration of TSP in Alashan (where the dust storm originated) on the day of the AD event reached $1824.7\;{\mu}g/m^3$, this being the highest concentration of air particles observed during the sampling period. The level was decreased to 15% of this ($274.7\;{\mu}g/m^3$) in Seoul and to 8.7% ($159.0\;{\mu}g/m^3$) in Gosan when the AD was observed two days later in Korea. Gosan, a representative background site in East Asia, displayed the lowest concentration of particles, with this maximal TSP concentration of $159\;{\mu}g/m^3$. Inorganic element contents in the air particles were also measured, and the concentrations in the four different regions compared. Concentrations of anthropogenically-enriched heavy metals in $PM_{10}$ and $PM_{2.5}$, such as lead, arsenic, cadmium, and mercury, were higher in the metropolitan cities of Beijing and Seoul compared to non-industrialized regions of Alashan and Gosan. However, the concentrations of inorganic soil elements including iron, magnesium, aluminum sodium, and manganese, were higher in Alashan compared to those in other sampling sites.

  • This study explores the barrier factors of Chinese private-owned enterprises in overseas expansion in terms of corruption, political risk, market fluctuation, cultural difference, and firms resource endowments. To explore the existing practical backgrounds, it was investigated to private-owned enterprises dealing with foreign export companies where run business in Hohhot, Baotou and Ordos, Inner Mongolia, China. The result shows that the corruption and political risks of host countries do not have significant influence on business performance in 'Go global' strategy, while the market fluctuation of host countries has a negative effect on business performance. Cultural difference has a negative effect on business performance, and enterprises' resource endowments have a positive effect on business performance in 'Go global' strategy. Additionally, interviewees provide several substantial suggestions regarding the government policy and industry ecosystem to surmount the barriers of POEs' going global. Lastly, the authors discuss managerial implications and provide several suggestions for the future studies.
