Purpose: The incidence of allergen specific immunotherapy-related systemic reactions (SRs) varies among different studies, and many factors are likely to contribute to SRs. This study aims to investigate the incidence, characteristics, and risk factors of SRs to standardize dust mite-specific subcutaneous immunotherapy (SCIT) in Central China. Methods: All patients receiving standardized dust mites (100-100,000 SQ-U/mL; Alutard SQ, Hørsholn, Denmark) immunotherapy were followed up. Recorded data included demographics, diagnosis, patient status, pulmonary function testing results before and after each injection, allergen dosage, and details of SRs. Results: From June 2011 to August 2014, a total of 208 patients received 4,369 injections; 27 (13.0%) patients experienced 48 (1.1%) systemic reactions. Most of the SRs were grade 2 reactions (n=30, 62.5%), followed by grade 1 (n=11, 22.9%), grade 3 (n=7, 14.6%), and no fatal reactions occurred. Forty-six SRs (95.8%) occurred within 30 minutes. Higher SR rates were associated with high concentration extracts (100,000 SQ-U/mL), injections with concomitant local reactions (LRs), children, asthma and high sensitivity (skin prick test 3+/4+ and/or sIgE≥17.5 kUA/L) (P<0.05). The estimated odds of SRs increased in children (OR=6.57; 95% CI: 1.88-22.97, P=0.003), asthmatic patients (OR=4.10; 95% CI: 1.72-9.80, P=0.002), and injections with LRs (OR=2.41; 95% CI: 1.33-4.36, P=0.004).Conclusions: The incidence of SRs to dust mite SCIT was low, and multiple factors were associated with the increased incidence of SRs. Children, asthmatics and patients with concomitant LR may be prone to develop SRs.

Wang, Nan,Lee, Dong-Young,Li, Xiang-Yu 한국상업교육학회 2019 상업교육연구 Vol.33 No.5

중국정부는 인구수를 기반으로 한 새로운 도시화라는 개념을 제안하고 있다, 새로 운 도시화를 촉진하려면 많은 자금지원이 필요하기 때문에 금융 지원은 새로운 도시 화를 위한 중요한 자금원이다. 본 연구는 인구와 소득 요인을 고려하여 도시화에 대 한 재무 상관비율과 재무 효율성 영향을 분석하였다. 이를 위해, 2006년부터 2015년까 지 하북성 11 개 도시의 데이터를 대상으로 회귀모형을 구축하였다. 분석결과를 보면 재무 상관비율은 인구도시화수준과 유의한 양의 상관관계를 갖고 있어 인구도시화 수준을 향상시키는데 도움이 된다. 재무 효율성과 인구도시화 사이 에는 유의한 상관관계가 나타나지 않아 재무 효율성이 인구 도시화에 영향을 미치지 못한 것을 볼 수 있다. 재무 상관비율 및 재무 효율성은 소득도시화와 유의하지 않은 상관관계가 나타나기 때문에 재무 지원이 소득도시화의 수준을 높이는데 효과적이지 못하다는 것을 보여준다. 이를 바탕으로, 본 연구는 관련정책을 제안하며 하북성의 새 로운 도시화건설 및 재무 조정개발을 위한 의사결정의 근거를 제공한다. The Chinese government puts forward the people-oriented concept of new urbanization on the basis of urbanization. The promotion of new urbanization requires a large amount of financial support, and financial support is an important source of funds for the new urbanization process. Based on the availability of data, this paper selects the panel data of 11 cities in Hebei Province from 2006 to 2015 and analyzes the influences of financial interrelations ratio and financial efficiency on population urbanization rate and income urbanization rate respectively by constructing a regression model. The analysis results show that the financial interrelations ratio has a significant positive correlation with population urbanization rate, which is conducive to improving the level of population urbanization rate. There is no significant correlation between financial efficiency and population urbanization rate, indicating that this factor has little effect on population urbanization rate. Financial interrelations ratio and financial efficiency show no significant correlation with income urbanization rate, indicating that the impact of financial support on raising the level of income urbanization is not obvious. According to the analysis results, this paper puts forward relevant recommendation to provide decision-making basis for the new urbanization construction and financial development in Hebei province.

Wang, Feng-Liang,Chen, Fei,Yin, Hong,Xu, Nan,Wu, Xiao-Xiang,Ma, Jing-Jing,Gao, Shen,Tang, Jin-Hai,Lu, Cheng Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.4

Purpose: Mammography has been confirmed as the only effective mode to improve the prognosis of patients with breast cancer in Western developed countries, but might not be a good choice in other areas of the world. One of the major challenges in China is to determine an optimal imaging modality for breast cancer screening. This study was designed to clarify the sensitivity of ultrasonography compared with that of mammography in rural China. Methods: We retrospectively studied the sensitivity of mammography and ultrasonography based on 306 breast cancer patients detected by the program of "screening for cervical cancer and breast cancer" performed in Chinese rural areas between January 2009 and December 2011, and analyzed the effects of age, breast density and volume on the sensitivity. Results: Stratified analysis showed that the sensitivity of breast ultrasonography was significantly higher than that of mammography in premenopausal patients (81.4% vs. 61.1%, p=0.02), in women ${\leq}$ 55 years of age (82.2% vs. 63.4%, p<0.01), in the high breast density group (American College of Radiology [ACR] levels 3-4) (85.9% vs. 60.6%, p<0.01) and in the small breast volume group (${\leq}$ 400 ml) (87.1% vs. 66.7%, p<0.01). Age had a significant effect on sensitivity of mammography (breast density and volume-adjusted odds ratio, 6.39; 95% confidence interval, 2.8-14.4 in age group > 55 compared to age group ${\leq}$ 45), but not that of ultrasonography. Neither breast density nor volume had significant effect on sensitivity of mammography or ultrasonography. Conclusions: Ultrasonography is more sensitive than mammography in detecting breast cancer in women under 55 year-old Chinese, especially in those with high-density and relatively small breasts.

Acute ischaemic stroke (AIS) seriously affects patient quality of life. We explored the role of the intestinal microbiota on oxidative stress and autophagy in stroke, and Astragaloside IV (AS-IV) reversed the changes induced by intestinal microbiota. We determined the characteristics of the intestinal microbiota of AIS and transient ischaemic attack (TIA) patients by 16S sequencing and found that the structure and diversity of the intestinal microbiota in patients with AIS and TIA were significantly different from those in healthy subjects. Specifically, the abundance of genus Bifidobacterium, Megamonas, Blautia, Holdemanella, and Clostridium, content of homocysteine and triglyceride was increased significantly, thus it may be as a potential mechanism of AIS and TIA. Furthermore, germ-free mice were infused intracolonically with fecal supernatants of TIA and AIS with/without feed AS-IV for 12 weeks, and we found that the feces of AIS up-regulated the autophagy markers Beclin-1, light chain 3 (LC3)-II and autophagy-related gene (Atg)12, and the expression of reactive oxygen species (ROS) and NADPH oxidase 2/4 (NOX2/4), malondialdehyde (MDA), however, the expression of total antioxidant capacity (T-AOC) and activity of superoxide dismutase (SOD) and glutathione (GSH) was down-regulated in brain tissue, the content of homocysteine and free fatty acids (FFA) in serum of the mice. Meanwhile, AS-IV could reverse the above phenomenon, however, it does not affect the motor function of mice. AS-IV reversed these changes and it may be a potential drug for AIS therapeutics.

Cheng-Xiang Guo,Yi-Nan Shen,Qi Zhang,Xiao-Zhen Zhang,Jun-Li Wang,Shun-Liang Gao,Jian-Ying Lou,Ri-Sheng Que,Tao Ma,Ting-Bo Liang,Xue-Li Bai 대한외과학회 2020 Annals of Surgical Treatment and Research(ASRT) Vol.98 No.2

Purpose: The International Study Group on Pancreatic Fistula’s definition of postoperative pancreatic fistula (POPF) has recently been updated. This study aimed to identify risk factors for POPF in patients having pancreaticoduodenectomy (PD) and to generate a nomogram to predict POPF. Methods: Data on 298 patients who underwent PD from March 2012 to October 2017 was retrospectively reviewed and POPF statuses were redefined. A nomogram was constructed using data from 220 patients and validated using the remaining 78 patients. Independent risk factors for POPF were identified using univariate and multivariate analyses. A predictive nomogram was established based on the independent risk factors and was compared with existing models. Results: Texture of the pancreas, size of the main pancreatic duct, portal vein invasion, and definitive pathology were the identified risk factors. The nomogram had a C-index of 0.793 and was internally validated. The nomogram performed better (C-index of 0.816) than the other most cited models (C-indexes of 0.728 and 0.735) in the validation cohort. In addition, the nomogram can assign patients into low- (less than 10%), intermediate- (10% to 30%), and high-risk (equal or higher than 30%) groups to facilitate personalized management. Conclusion: The nomogram accurately predicted POPF in patients having PD.

Yu, Li-Xiang,Zhou, Nan-Nan,Liu, Li-Yuan,Wang, Fei,Ma, Zhong-Bing,Li, Jie,Yu, Zhi-Gang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.18

Many studies have indicated possible associations between a polymorphism of adiponectin receptor 1 (ADIPOR1) rs1342387 and risk of cancer, but contradictory results have been reported. The main aim of this study was to draw a reliable conclusion about the relationship between the rs1342387 polymorphism and cancer incidence, by conducting a literature search of Pubmed, Embase, Wanfang and Cochrane libraries. Eleven studies including 3, 738 cases and 4, 748 controls were identified in this meta-analysis. The ADIPOR1 rs1342387 polymorphism was associated with risk of colorectal cancer for all genetic comparison models (GG vs AA, OR: 1.44, 95%CI: 1.21-1.70; G carriers vs A carriers, OR: 1.23, 95%CI: 1.11-1.36; dominant model, OR: 1.28, 95%CI: 1.10-1.49 and recessive model, OR: 1.31, 95%CI: 1.12-1.55). Stratified by ethnicity, the rs1342387 polymorphism was significantly associated with risk of colorectal cancer in Asian ancestry for all genetic comparison models (GG vs AA, OR: 1.56, 95%CI: 1.26-1.92; G carriers vs. A carriers OR: 1.30, 95%CI: 1.18-1.43; dominant model OR: 1.31, 95%CI: 1.08-1.60 and recessive model OR: 1.44, 95%CI: 1.26-1.64), but not in Caucasian or mixed (Caucasian mainly) groups. In summary, the ADIPOR1 rs1342387 polymorphism is significantly associated with risk of colorectal cancer among individuals of Asian ancestry.

Jie Chen,Chun-Xiang Tian,Miao Yu,Qing Lv,Nan-Sheng Cheng,Zu Wang,Xi Wu 한국유방암학회 2014 Journal of breast cancer Vol.17 No.1

Purpose: The aim of the study was to evaluate the efficacy andsafety of combining sorafenib with chemotherapy in patients withhuman epidermal growth factor receptor 2 (HER2)-negative advancedbreast cancer. Methods: MEDLINE, EMBASE, CochraneCentral Register of Controlled Trials, American Society for ClinicalOncology abstracts, and European Society for Medical Oncologyabstracts were searched. Randomized clinical trials that comparedthe efficacy and safety of sorafenib plus chemotherapy inpatients with HER2-negative advanced breast cancer with placeboplus chemotherapy were eligible. The endpoints were progression-free survival (PFS), overall survival (OS), time to progression(TTP), duration of response (DOR), overall response rate(ORR), clinical benefits, and adverse effects. The meta-analysiswas performed using Review Manager 5.2.6 (The Nordic CochraneCentre), and the fixed-effect model weighted by the Mantel-Haenszel method was used. When considerable heterogeneitywas found (p<0.1), further analysis (subgroup analysis, sensitivityanalysis, or random-effect model) was performed to identifythe potential cause. The results are expressed as hazard ratios orrisk ratios, with their corresponding 95% confidence intervals. Results: The final analysis included four trials comprising 844 patients. The results revealed longer PFS and TTP, and higher ORRand clinical benefit rates in patients receiving sorafenib combinedwith chemotherapy compared to those receiving chemotherapyand placebo. OS and DOR were similar in the two groups. Meanwhile,the incidence of some adverse effects, including hand-footskin reaction/hand-foot syndrome, diarrhea, rash, and hypertension,were significantly higher in the sorafenib arm. Conclusion:Sorafenib combined with chemotherapy may prolong PFS andTTP. This treatment was associated with manageable toxicities,but frequent dose interruptions and reductions were required.

Jin, Yong-Xun,Cui, Xiang-Shun,Yu, Xian-Feng,Lee, Sung-Hyun,Wang, Qing-Ling,Gao, Wei-Wei,Xu, Yong-Nan,Sun, Shao-Chen,Kong, IL-Keun,Kim, Nam-Hyung Cambridge University Press 2012 Zygote Vol.20 No.4

<B>Summary</B><P>Interspecies intracytoplasmic sperm injection has been carried out to understand species-specific differences in oocyte environments and sperm components during fertilization. While sperm aster organization during cat fertilization requires a paternally derived centriole, mouse and hamster fertilization occur within the maternal centrosomal components. To address the questions of where sperm aster assembly occurs and whether complete fertilization is achieved in cat oocytes by interspecies sperm, we studied the fertilization processes of cat oocytes following the injection of cat, mouse, or hamster sperm. Male and female pronuclear formations were not different in the cat oocytes at 6 h following cat, mouse or hamster sperm injection. Microtubule asters were seen in all oocytes following intracytoplasmic injection of cat, mouse or hamster sperm. Immunocytochemical staining with a histone H3-m2K9 antibody revealed that mouse sperm chromatin is incorporated normally with cat egg chromatin, and that the cat eggs fertilized with mouse sperm enter metaphase and become normal 2-cell stage embryos. These results suggest that sperm aster formation is maternally dependent, and that fertilization processes and cleavage occur in a non-species specific manner in cat oocytes.</P>

Non-interest Income, Profit, and Risk Efficiencies: Evidence from Commercial Banks in China

Wen-Long Bian,Xiang-Nan Wang,Qi-Xiang Sun 한국증권학회 2015 Asia-Pacific Journal of Financial Studies Vol.44 No.5

Chinese commercial banks are transforming their activities into more non-interest income businesses under a highly regulated financial system. This paper investigates the effects of this transformation on profit and risk efficiencies. We find that commission and fee income sig- nificantly reduce risk efficiency due to the circumvention of the regulation on deposit interest rate and the assumption of risk that should have been borne by customers. In terms of trad- ing income, it significantly reduces profit efficiency due to the upper limit of the loan-deposit ratio, the lack of investment channels and low returns of bond markets. The regulatory authorities are supposed to further liberalize the banking industry and grant banks more rights.

Long Noncoding RNA Cytoskeleton Regulator RNA Suppresses Apoptosis in Hepatoma Cells by Modulating the miR-125a-5p/HS1-Associated Protein X-1 Axis to Induce Caspase-9 Inactivation

Wu Zhen-Yu,Wang Yumin,Hu Hao,Ai Xiang-Nan,Zhang Qiang,Qin Yu-Gang 거트앤리버 소화기연관학회협의회 2023 Gut and Liver Vol.17 No.6

Background/Aims: The involvement of long noncoding RNAs in the carcinogenesis of hepatocellular carcinoma (HCC) has been well documented by substantial evidence. However, whether cytoskeleton regulator RNA (CYTOR) could affect the progression of HCC remains unclear. Methods: The relative expression of CYTOR, miR-125a-5p and HS1-associated protein X-1 (HAX-1) mRNA in HCC cells were determined via quantitative real-time polymerase chain reaction. The viability of treated HCC cells was measured by Cell Counting Kit-8 assay. Cell apoptosis was estimated by flow cytometry analysis, assessment of caspase-9 activity and terminal deoxynucleotidyl transferase dUTP nick-end labeling staining, and Western blot of apoptosis-related proteins. The interplay between CYTOR or HAX-1 and miR-125a-5p was validated by dual-luciferase reporter assay. Results: CYTOR was upregulated and miR-125a-5p was downregulated in HCC cells. CYTOR silencing inhibited cell proliferation and promoted cell apoptosis in HepG2 and SMMC-7721 cells. miR-125a-5p was sponged and negatively regulated by CYTOR, and HAX-1 was directly targeted and negatively modulated by miR-125a-5p. Overexpression of miR-125a-5p enhanced the repressive effects of CYTOR knockdown on HCC cells, and knockdown of HAX-1 enhanced the inhibitory effects of miR-125a-5p mimics on HCC cells. Conclusions: CYTOR silencing facilitates HCC cell apoptosis in vitro via the miR-125a-5p/HAX-1 axis.
