Background: The current study examined health-related quality of life (QoL) for patients with esophageal/gastric cardia precursor lesions or cancer before and after treatment to facilitate improved prevention and treatment. Materials and Methods: Patients with different stages of esophageal/gastric cardia lesions completed two QoL questionnaires, EORTC QLQ-C30 and supplemental QLQ-OES 18, before primary treatment, and at 1, 6 and 12 months after treatment. Results: Fifty-nine patients with precursor lesions, 57 with early stage cancer, and 43 with advanced cancer responded to our survey. Patients with precursor lesions or early stage cancer reported better QoL overall than those with advanced cancer before treatment (p<0.01). Global QoL scores before treatment and at 1 month after treatment were $71{\pm}9$ versus $69{\pm}9$ (p>0.01), $71{\pm}8$ versus $61{\pm}11$ (p<0.01), $67{\pm}11$ versus $62{\pm}9$ (p<0.01) for three stages of lesions. At 6 months after treatment, some QoL measures recovered gradually in precursor lesion and early cancer patients, while some continuously deteriorated in advanced cancer patients. At 12 months, all QoL scores were comparable to baseline for patients with precursor lesions (p>0.01), while global QoL, social, pain, and insomnia scores for early stage and advanced cancer were inferior to corresponding baseline levels (difference between means>5, p<0.01). At this time point, compared with patients with early stage cancer, those with advanced cancer showed worse QoL with all function and most symptom measures (p<0.01). Conclusions: Patients with precursor lesions or early stage esophageal/gastric cardia cancer show better QoL than those with advanced cancer. This indicates that screening, early diagnosis and treatment may improve the QoL for esophageal/gastric cardia cancer patients. Target intervention and counseling should be given by health care providers during treatment and follow-up to facilitate QoL improvement.

Objective: Hypermethylation of human papillomavirus (HPV) and host genes has beenreported in cervical cancer. However, the degree of methylation of different HPV typesrelative to the severity of the cervical lesions remains controversial. Studies of the degree ofmethylation associated with the host gene and the HPV genome to the severity of cervicallesions are rare. We examined the association of methylation status between host genes andlate gene 1 (L1) regions of HPV16, 18, 52, and 58 in cervical brushings. Methods: Cervical brushings from 147 HPV-infected patients were obtained. The samplescomprised normal (n=28), cervical intraepithelial neoplasia (CIN) 1 (n=45), CIN2 (n=13), andCIN3/carcinoma in situ (n=61). The methylation status of HPV and host genes was measuredusing bisulfite pyrosequencing and quantitative methylation-specific polymerase chainreaction (PCR). Results: The degree of methylation of L1 in HPV16, 18, and 52 was associated with theseverity of the cervical lesion. In HPV52, C-phosphate-G (CpG) sites 6368m, 6405m, and6443m showed significantly higher methylation in lesions ≥CIN3 (p=0.005, 0.003, and0.026, respectively). Methylation of most HPV types except HPV52 (r<−0.1) was positivelycorrelated with the degree of methylation of host genes including PAX1 and SOX1 (0.4≤r≤0.7). Combining HPV methylation with PAX1 methylation improved the clustering for ≥CIN2. Conclusion: Our study showed that the degree of L1 methylation of HPV16, 18, and 52but not 58 is associated with the severity of cervical lesions. The association betweenHPV methylation and host gene methylation suggests different responses of host cellularepigenetic machinery to different HPV genotypes.

Assessment of Air Temperature Trends in the Source Region of Yellow River and Its Sub-Basins, China

Mudassar Iqbal,Jun Wen,Xin Wang,Yongchao Lan,Hui Tian,Muhammad Naveed Anjum,Muhammad Adnan 한국기상학회 2018 Asia-Pacific Journal of Atmospheric Sciences Vol.54 No.1

Changes in climatic variables at the sub-basins scale (having different features of land cover) are crucial for planning, development and designing of water resources infrastructure in the context of climate change. Accordingly, to explore the features of climate changes in sub-basins of the Source Region of Yellow River (SRYR), absolute changes and trends of temperature variables, maximum temperature (Tmax), minimum temperature (Tmin), mean temperature (Tavg) and diurnal temperature range (DTR), were analyzed annually and seasonally by using daily observed air temperature dataset from 1965 to 2014. Results showed that annual Tmax, Tmin and Tavg for the SRYR were experiencing warming trends respectively at the rate of 0.28, 0.36 and 0.31oC (10 yr)−1. In comparison with the 1st period (1965-1989), more absolute changes and trends towards increasing were observed during the 2nd period (1990-2014). Apart from Tangnaihai (a low altitude sub-basin), these increasing trends and changes seemed more significant in other basins with highest magnitude during winter. Among sub-basins the increasing trends were more dominant in Huangheyan compared to other sub-basins. The largest increase magnitude of Tmin, 1.24 and 1.18oC (10 yr)−1, occurred in high altitude sub-basins Jimai and Huangheyan, respectively, while the smallest increase magnitude of 0.23oC (10 yr)−1 occurred in a low altitude sub-basin Tangnaihai. The high elevation difference in Tangnaihai probably was the main reason for the less increase in the magnitude of Tmin. In the last decade, smaller magnitude of trend for all temperature variables signified the signal of cooling in the region. Overall, changes of temperature variables had significant spatial and seasonal variations. It implies that seasonal variations of runoff might be greater or different for each sub-basin.

Pan, Xiong-Fei,Wen, Ying,Loh, Marie,Wen, Yuan-Yuan,Yang, Shu-Juan,Zhao, Zhi-Mei,Tian, Zhi,Huang, He,Lan, Hui,Chen, Feng,Soong, Richie,Yang, Chun-Xia Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

Background: Gastric carcinogenesis is a complicated process that involves environmental and genetic factors like interleukin-4 (IL-4) and IL-8. Single nucleotide polymorphisms in their genes are associated with changed levels of gene expression. Here, we investigated the association between IL4-590 C>T and IL8-251T>A and gastric cancer (GC) risk in Sichuan of Southwestern China. Materials and Methods: We surveyed the research subjects using a self-designed questionnaire with questions on demographic factors and putative risk factors. Approximately 2-5ml of whole blood was collected after field survey to analyze IL4-590 C>T and IL8-251T>A genotypes using MALDI-TOF MS. Results: Our study recruited 308 pairs of GC patients and controls, including 224 (72.7%) men and 84 (27.3%) women in each group. There were 99 cardia and 176 noncardia GC patients in the case group. The case and control groups had an average age of $57.7{\pm}10.6$ ($mean{\pm}SD$) and $57.6{\pm}11.1$ years. GC patients reported a significantly greater proportion of family history of cancer (29.9% vs 10.7%, p<0.01) and drinking (54.6% vs 43.2%, p<0.01) than did controls. Variant genotypes of IL-4-590 C>T and IL-8-251 T>A were not associated with overall GC risk (adjusted OR, 0.89; 95%CI, 0.61-1.28 for CT or CC vs TT; adjusted OR, 1.14; 95%CI, 0.86-1.79 for TA or AA vs TT). Stratification analysis of two SNPs for risk by subsites only found that variant IL-8-251 TA or AA genotype was associated with increased noncardia GC risk (adjusted OR, 2.58; 95%CI, 1.19-5.57). We did not observe interactions between the IL-8-251 T>A genotype and smoking (adjusted OR, 0.38; 95%CI, 0.08-1.79) or drinking (adjusted OR, 0.36; 95%CI, 0.08-1.65) for risk of noncardia GC. Conclusions: Our data indicate no association between the two SNPs of IL-4-590 and IL-8-251 with overall GC risk, while the IL-8-251 TA or AA genotype conferred risk of cardia GC. Our findings contribute to the evidence body for risk of SNPs associated with the development of gastric cancer in this region.

Ning Zhang,Weiguang Ye,Tianlong Wang,Hui Wen,Lan Yao 한국유전학회 2020 Genes & Genomics Vol.42 No.4

Background Postoperative cognitive dysfunction (POCD) had a great relationship with anesthesia during surgery, and miRNAs have been found involved in anesthesia-induced cognitive impairment. Objective To explore the role and potential mechanism of miR-106a in isoflurane anesthesia-induced cognitive impairment. Methods Adult male mice were treated with isoflurane anesthesia; Morris water maze tests and fear conditioning tests were performed; and expression levels of miR-106a and LIMK1 were determined by quantitative real-time PCR (qRT-PCR) and western blot. Dual luciferase reporter assay was used to determine the binding of miR-106a and 3’UTR of LIMK1. To verify the role of miR-106a, antagomir of miR-106a were intrahippocampally injected. Finally, expression of BCL2 apoptosis regulator (Bcl-2), LIM domain kinase 1 (LIMK1), BCL2-associated X, apoptosis regulator (Bax) and cleaved caspase3 was determined by western blot. Results In isoflurane anesthesia-treated group (IS), the percentage of target quadrant dwell time was significantly lower and the escape latency was significantly higher than in the control group (sham), and the freezing behavior of IS was significantly less in contextual fear conditioning tests. Expression levels of miR-106a were increased and those of LIMK1 were decreased in response to IS. Dual luciferase reporter assay showed that miR-106a could bind with the 3’UTR of LIMK1. Decreased expression levels of miR-106a improved the cognitive impairment of the mice treated with isoflurane. Intrahippocampally injected antagomir of miR-106a also increased LIMK1 and Bcl-2 levels, decreased the BAX and cleaved caspase3 expression levels in the mice treated with isoflurane. Conclusion Decrease of LIMK1 expression by miR-106a played an important role in isoflurane anesthesia-induced cognitive impairment.

African Maternal Origin and Genetic Diversity of Chinese Domestic Donkeys

Lei, Chu-Zhao,Ge, Qing-Lan,Zhang, Hu-Cai,Liu, Ruo-Yu,Zhang, Wei,Jiang, Yong-Qing,Dang, Rui-Hua,Zheng, Hui-Ling,Hou, Wen-Tong,Chen, Hong Asian Australasian Association of Animal Productio 2007 Animal Bioscience Vol.20 No.5

The origin of domestic donkeys in China has been controversial. To clarify the origin of Chinese domestic donkeys, we investigated the partial mitochondrial D-loop sequences of 126 samples from 12 native breeds. The results revealed two mitochondrial origins, lineage Somali and lineage Nubian of African wild ass detected in Chinese domestic donkeys. Lineage Somali was predominant in Chinese domestic donkey breeds. The pattern of genetic variation in ass mtDNA D-loop sequences indicated that the two lineages Somali and Nubian from China had undergone population expansion events. In a combined analysis of lineages Somali and Nubian between previously published sequences from other countries/regions and sequences of Chinese domestic donkeys, the results indicated that the two lineages of Chinese domestic donkeys were from Africa and supported the African maternal origins of Chinese domestic donkeys. There was no obvious geographical structure in Chinese domestic donkey breeds, but the population showed abundant mtDNA diversity. The spread routes of Chinese domestic donkeys were also discussed.

Ginsenoside Rh2 reduces depression in offspring of mice with maternal toxoplasma infection during pregnancy by inhibiting microglial activation via the HMGB1/TLR4/NF-kB signaling pathway

Xiang Xu,Yu-Nan Lu,Jia-Hui Cheng,Hui-Wen Lan,Jing-Mei Lu,Guang-Nan Jin,Guang-Hua Xu,Cheng-Hua Jin,Juan Ma,Hu-Nan Piao,Xuejun Jin,Lian-Xun Piao 고려인삼학회 2022 Journal of Ginseng Research Vol.46 No.1

Background: Maternal Toxoplasma gondii (T. gondii) infection during pregnancy has been associated with various mental illnesses in the offspring. Ginsenoside Rh2 (GRh2) is a major bioactive compound obtained from ginseng that has an anti-T. gondii effect and attenuates microglial activation through toll-like receptor 4 (TLR4)/nuclear factor-kappa B (NF-kB) signaling pathway. GRh2 also alleviated tumor-associated or lipopolysaccharide-induced depression. However, the effects and potential mechanisms of GRh2 on depression-like behavior in mouse offspring caused by maternal T. gondii infection during pregnancy have not been investigated. Methods: We examined GRh2 effects on the depression-like behavior in mouse offspring, caused by maternal T. gondii infection during pregnancy, by measuring depression-like behaviors and assaying parameters at the neuronal and molecular level. Results: We showed that GRh2 significantly improved behavioral measures: sucrose consumption, forced swim time and tail suspended immobility time of their offspring. These corresponded with increased tissue concentrations of 5-hydroxytryptamine and dopamine, and attenuated indoleamine 2,3-dioxygenase or enhanced tyrosine hydroxylase expression in the prefrontal cortex. GRh2 ameliorated neuronal damage in the prefrontal cortex. Molecular docking results revealed that GRh2 binds strongly to both TLR4 and high mobility group box 1 (HMGB1). Conclusion: This study demonstrated that GRh2 ameliorated the depression-like behavior in mouse offspring of maternal T. gondii infection during pregnancy by attenuating the excessive activation of microglia and neuroinflammation through the HMGB1/TLR4/NF-kB signaling pathway. It suggests that GRh2 could be considered a potential therapy in preventing and treating psychiatric disorders in the offspring mice of mothers with prenatal exposure to T. gondii infection.
