Objective: To investigate the changes of serum vascular endothelial growth factor (VEGF), soluble interleukin-2 receptor (SIL-2R) and hepatocyte growth factor (HGF) contents in patients with primary hepatocellular carcinoma (HCC) before and after percutaneous microwave coagulation therapy (PMCT) and determine their clinical significance. Materials and Methods: Fasting venous blood (3 mL) from 81 patients with primary HCC diagnosed by pathology was collected in the mornings 1 day before PMCT, and 1 day, 7 days and 1 month after PMCT, and then the serum was separated and stored in $-70^{\circ}C$. The contents of VEGF, SIL-2R and HGF were detected by enzyme linked immunosorbent assay (ELISA). Results: The serum VEGF, SIL-2R and HGF contents in 81 patients with primary HCC had obviously dynamic changes before and after PMCT. By comparison to 1 day after PMCT with pre-operation, there was no statistical significance regarding VEGF and SIL-2R contents (P>0.05), but HGF content showed significant difference (P<0.01). Compared with pre-operation, VEGF, SIL-2R and HGF contents 7 days and 1 month after PMCT all manifested significant differences (P<0.01). By comparison to 7 days with 1 month after PMCT, there was no statistical significance regarding the VEGF content (P>0.05), whereas SIL-2R and HGF contents showed significant change (P<0.01). Conclusions: The contents of serum VEGF, SIL-2R and HGF have obviously dynamic changes in primary HCC before and after PMCT, and their joint detection is expected to be an effective hematologic evaluation index of PMCT for primary HCC.

이번 연구는 남원식 추어탕의 주재료인 추어와 무청시래기에 대한 인식개선과 이를 이용하여 젊은 연령층의 기호도에 적합한 분쇄육 제품을 개발하고자 추진되었다. 떡갈비 주원료인 돈육과 우지의 15%를 추어 페이스트로 대체한 추어 떡갈비를 대조구로 사용하였으며, 대파의 일정비율(25%, 50%, 75%, 100%)을 무청시래기로 대체하여 추어와 무청시래기가 첨가된 떡갈비 시료를 제조하였다. 무청시래기를 첨가한 떡갈비는 가열·조리 후 pH와 당도는 각각 6.07-6.28과 9.94-10.9로 시중에서 유통되는 떡갈비의 개별 특성에 적합하였다. 가열·조리에 따른 가열감량은 대파를 사용한 대조구에 비하여 대파를 무청시래기로 대체한 떡갈비 시료에서 유의적으로 낮았지만 무청시래기의 첨가량에 따른 유의적인 차이는 없었다. 가열 전과 가열·조리 후 무청시래기를 첨가한 떡갈비의 수분함량은 모두 대조구 보다 높았으며 이는 무청시래기의 식이섬유가 육가공품의 보수성을 높여 가열감량을 감소시킨 것으로 판단되었다. 대파를 무청시래기로 대체한 떡갈비 시료의 명도(44.5-47.8)는 시료 간의 유의적인 차이를 보이지 않은 반면 적색도(0.77-4.97)와 황색도(6.92-12.8)는 무청시래기의 첨가량에 따라 유의적으로 감소하였다. 떡갈비 시료에 대한 TPA 결과, 부착성은 대파를 무청시래기로 대체한 떡갈비 시료에서 대조구보다 유의적으로 낮아졌으나 경도, 응집성, 검성, 씹힘성에서는 대조구와 무청시래기를 첨가한 시료 간에 유의적인 차이를 확인할 수 없었다. 무청시래기가 첨가된 떡갈비 시료에 대한 관능적인 평가에서 색, 연도, 다즙성에서 대조구보다 낮은 점수를 받았다. 전반적인 기호도 역시 무청시래기가 첨가되지 않은 대조구에서 가장 높은 점수를 받았으나 무청시래기를 첨가한 시료에서는 대파의 50%를 대체한 시료에서 높은 점수를 받았다. 무청시래기 자체가 지닌 특유의 향미는 관능적인 평가에서 확인되지 않았으며 전자코를 이용한 향기패턴 분석에서도 낮은 분별지수(-90)로 시료 간의 향기패턴 차이를 확인하기 어려운 수준이었다. 이번 연구를 통해 떡갈비의 제조에서 대파를 대체하는 무청시래기의 함량은 25-50%가 적절하였으며 무청시래기와 추어가 지닌 특유의 맛과 냄새로 인한 영향을 받지 않는 떡갈비를 개발함으로써 향후 남원지역의 향토음식과 연계되는 새로운 메뉴개발이 가능하게 되었다. This study was performed to develop tteokgalbi suitable for young-aged individuals by using mudfish and radish greens, major ingredients of Chueo-tang. Mudfish-tteokgalbi (control), in which 15% of the meat and tallow was replaced with mudfish paste, was used while substituting 25 to 100% of the green onions with radish greens. The pHs and sugar contents of the tteokgalbi developed in this study were 6.07-6.28 and 9.94-10.9, respectively, and it was suitable for tteokgalbi sold in the market. Replacing green onions with radish greens while manufacturing tteokgalbi significantly reduced the color (a and b values) and weight loss during cooking compared to the control. Replacing green onions with increasing quantities of radish greens also significantly reduced the adhesiveness of the samples in the texture profile analysis. Although the overall acceptability of the control was the best, the ideal quantity of radish greens as a substitution for green onions appears to be 25-50%. The unique flavor of the supplemented radish greens was indistinguishable in the sensory evaluation and the principal component analysis with an electronic nose. Finally, radish greens were confirmed as a good ingredient for manufacturing tteokgalbi together with mudfish paste.

He Jun,Ji-chen Yang,Qing-hua Zhang,Guo-xi Sun,Jian-bing Xiong 보안공학연구지원센터 2014 International Journal of Control and Automation Vol.7 No.12

In this brief, a novel pathological continuous speech detection method based on time domain features weighted. First, different optimal threshold for time domain features, including zero crossing ratio, short-time energy and autocorrelation, are obtained from training speech data. Second, a difference evaluation technique is proposed, and with it, the difference of the same time domain feature selected from testing speech data and training speech data were obtained. Finally, to distinguish a given speech well, a novel weighting method based on difference evaluation for each kinds of time domain is employed, respectively. Experiments were conducted on the pathological speech database to prove the power and effectiveness of the proposed method. Results obtained shown that this method outperforms other early proposed time domain feature method, creating a more reliable technique for pathological continuous speech detection.

Objective: To analyze the sociodemographic and clinical factors related to anxiety in patients with major depressive disorder (MDD). Methods: This study involved a secondary analysis of data obtained from the Diagnostic Assessment Service for People with Bipolar Disorders in China (DASP), which was initiated by the Chinese Society of Psychiatry (CSP) and conducted from September 1, 2010 to February 28, 2011. Based on the presence or absence of anxiety-related characteristics, 1,178 MDD patients were classified as suffering from anxious depression (n=915) or non-anxious depression (n=263), respectively. Results: Compared with the non-anxious group, the anxious-depression group had an older age at onset (t=−4.39, p<0.001), were older (t=−4.69, p<0.001), reported more lifetime depressive episodes (z=−3.24, p=0.001), were more likely to experience seasonal depressive episodes (χ2=6.896, p=0.009) and depressive episodes following stressful life events (χ2=59.350, p <0.001), and were more likely to have a family history of psychiatric disorders (χ2=6.091, p=0.014). Their positive and total scores on the Mood Disorder Questionnaire (MDQ) and the 32-item Hypomania Checklist (HCL-32) (p<0.05) were also lower. The logistic regression analysis indicated that age (odds ratio [OR]=1.03, p<0.001), a lower total MDQ score (OR=0.94, p=0.011), depressive episodes following stressful life events (OR=3.04, p<0.001), and seasonal depressive episodes (OR=1.75, p=0.039) were significantly associated with anxious depression. Conclusion: These findings indicate that older age, fewer subclinical bipolar features, an increased number of depressive episodes following stressful life events, and seasonal depressive episodes may be risk factors for anxiety-related characteristics in patients with MDD.

Association of IgE-mediated allergen sensitivity and promoter polymorphisms of chemokine (C–C motif) ligand 5 gene in Han Chinese patients with allergic skin diseases

Ji-Chang Zhou,Yu-Mei Zhu,Zheng Chen,Shan He,Shi-jie Zheng,Jun-luan Mo,Xiao-Li Liu,Chun-mei Gong,Bin Hou,Hui Yang 한국유전학회 2015 Genes & Genomics Vol.37 No.5

Two single nucleotide polymorphisms (SNPs), rs2280788 (-28C[G) and rs2107538 (-403G[A), in the promoter region of chemokine (C–C motif) ligand 5 (CCL5) was reported to be involved in the immunoglobulin E (IgE) expression and IgE-mediated allergic reactions. This study was to investigate the characteristics of total serum IgE level, specific allergen sensitivities and the two SNPs in the allergic skin disease (ASD) patients. ASD patients visiting the dermatological outpatient department of a local hospital were included with certain criteria, and the fasting venous blood was sampled for analysis. Total serum IgE was assayed with an ELISA kit, and 14 kinds of allergen-specific IgE were tested with an allergen screening system. The polymerase chain reaction–restriction fragment length polymorphism method was used to analyze the two SNPs. Among the finally included 437 patients aged from 16 to 85 years, 68.2 % was positive for the total serum IgE, 49.2 % was positive for at least one of the assayed allergen-specific IgE, and 35.0 % was sensitive to house dust mite. In the SNPs analysis, the GG/(GA?AA) ratio and G/A ratio for the -403G[A locus in the male and/or female C45 years subgroup were significantly lower in the total serum IgE positive patients than in the negative patients (P\0.05). Weak linkage disequilibrium was found between -403A and -28C alleles in male subgroups adjusted by age. Conclusively, house dust mite was the most common allergen in ASD patients, and -403A allele of CCL5 promoter was a risk factor for IgE-mediated sensitization.

Ji, Geng,Lin, Yuan,Cao, Song-Yu,Li, Luo-Zhu,Chen, Xin-Long,Sun, Bu-Mei,Chen, Chuan-Jun,Ma, Hong-Xia Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

The xeroderma pigmentosum complementation group C gene (XPC) has been identified as important for repairing UV-related DNA damage. Some subtle changes in this gene may impair repair efficiency and influence susceptibility to human cancers, including skin cancer. Two polymorphisms in XPC, 939A>C (rs2228001) and 499C>T (rs2228000), are considered to have possible associations with the risk of skin cancer, but the reported results have been inconsistent. Here we performed a meta-analysis of the available evidence regarding the relationship between these two polymorphisms and the risk of skin cancer. All relevant studies were searched using PubMed, Embase and Web of Science before February 2012. A total of 8 case-control studies were included in this analysis, and no convincing associations between the two polymorphisms and risk of skin cancer were observed in any of the genetic models. Stratified analyses by skin cancer type also did not detect significant associations in any subgroup. This meta-analysis suggested that the XPC 939A>C and 499C>T polymorphisms may have little involvement in susceptibility to skin cancer.

Schedule-Dependent Effects of Kappa-Selenocarrageenan in Combination with Epirubicin on Hepatocellular Carcinoma

Ji, Yu-Bin,Ling, Na,Zhou, Xiao-Jun,Mao, Yun-Xiang,Li, Wen-Lan,Chen, Ning Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.8

Hepatocellular carcinoma (HCC) has a relatively higher incidence in many countries of Asia. Globally, HCC has a high fatality rate and short survival. Epirubicin, a doxorubicin analogue, may be administered alone or in combination with other agents to treat primary liver cancer and metastatic diseases. However, the toxic effects of epirubicin to normal tissues and cells have been one of the major obstacles to successful cancer chemotherapy. Here, we investigated the effects of epirubicin in combination with kappa-selenocarrageenan on mice with H22 implanted tumors and HepG-2 cell proliferation, immune organ index, morphology, cell cycle and related protein expressions in vivo and in vitro with sequential drug exposure. The inhibitory rate of tumor growth in vivo was calculated. Drug sensitivity was measured by MTT assay, and the King's principle was used to evaluate the interaction of drug combination. Morphological changes were observed by fluorescent microscopy. Cell cycle changes were analyzed by flow cytometry. Expression of cyclin A, Cdc25A and Cdk2 were detected by Western blotting. In vivo results demonstrated that the inhibitory rate of EPI combined with KSC was higher than that of KSC or EPI alone, and the Q value indicated an additive effect. In addition, KSC could significantly raise the thymus and spleen indices of mice with H22 implanted tumors. In the drug sensitivity assay in vitro, exposure to KSC and EPI simultaneously was more effective than exposure sequentially in HepG-2 cells, while exposure to KSC prior to EPI was more effective than exposure to EPI prior to KSC. Q values showed an additive effect in the simultaneous group and antagonistic effects in the sequential groups. Morphological analysis showed similar results to the drug sensitivity assay. Cell cycle analysis revealed that exposure to KSC or EPI alone arrested the cells in S phase in HepG-2 cells, exposure to KSC and EPI simultaneously caused accumulation in the S phase, an effect caused by either KSC or EPI. Expression of cyclin A, Cdc25A and Cdk2 protein was down-regulated following exposure to KSC and EPI alone or in combination, exposure to KSC and EPI simultaneously resulting in the lowest values. Taken together, our findings suggest that KSC in combination with EPI might have potential as a new therapeutic regimen against HCC.

PD-L1 inhibits acute and chronic pain by suppressing nociceptive neuron activity via PD-1

Chen, Gang,Kim, Yong Ho,Li, Hui,Luo, Hao,Liu, Da-Lu,Zhang, Zhi-Jun,Lay, Mark,Chang, Wonseok,Zhang, Yu-Qiu,Ji, Ru-Rong NATURE AMERICA 2017 NATURE NEUROSCIENCE Vol.20 No.7

<P>Programmed cell death ligand-1 (PD-L1) is typically produced by cancer cells and suppresses immunity through the receptor PD-1 expressed on T cells. However, the role of PD-L1 and PD-1 in regulating pain and neuronal function is unclear. Here we report that both melanoma and normal neural tissues including dorsal root ganglion (DRG) produce PD-L1 that can potently inhibit acute and chronic pain. Intraplantar injection of PD-L1 evoked analgesia in naive mice via PD-1, whereas PD-L1 neutralization or PD-1 blockade induced mechanical allodynia. Mice lacking Pd1 (Pdcd1) exhibited thermal and mechanical hypersensitivity. PD-1 activation in DRG nociceptive neurons by PD-L1 induced phosphorylation of the tyrosine phosphatase SHP-1, inhibited sodium channels and caused hyperpolarization through activation of TREK2 K+ channels. PD-L1 also potently suppressed nociceptive neuron excitability in human DRGs. Notably, blocking PD-L1 or PD-1 elicited spontaneous pain and allodynia in melanoma-bearing mice. Our findings identify a previously unrecognized role of PD-L1 as an endogenous pain inhibitor and a neuromodulator.</P>

Analysis of Small Fragment Deletions of the APC gene in Chinese Patients with Familial Adenomatous Polyposis, a Precancerous Condition

Chen, Qing-Wei,Zhang, Xiao-Mei,Zhou, Jian-Nong,Zhou, Xin,Ma, Guo-Jian,Zhu, Ming,Zhang, Yuan-Ying,Yu, Jun,Feng, Ji-Feng,Chen, Sen-Qing Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

Background: : Familial adenomatous polyposis (FAP) is an autosomal dominant inherited disease mainly caused by mutations of the adenomatous polyposis coli (APC) gene with almost complete penetrance. These colorectal polyps are precancerous lesions that will inevitable develop into colorectal cancer at the median age of 40-year old if total proctocolectomy is not performed. So identification of APC germline mutations has great implications for genetic counseling and management of FAP patients. In this study, we screened APC germline mutations in Chinese FAP patients, in order to find novel mutations and the APC gene germline mutation characteristics of Chinese FAP patients. Materials and Methods: The FAP patients were diagnosed by clinical manifestations, family histories, endoscope and biopsy. Then patients peripheral blood samples were collected, afterwards, genomic DNA was extracted. The mutation analysis of the APC gene was conducted by direct polymerase chain reaction (PCR) sequencing for micromutations and multiplex ligation-dependent probe amplification (MLPA) for large duplications and/or deletions. Results: We found 6 micromutations out of 14 FAP pedigrees, while there were no large duplications and/or deletions found. These germline mutations are c.5432C>T(p. Ser1811Leu), two c.3926_3930delAAAAG (p.Glu1309AspfsX4), c.3921_3924delAAAA (p.Ile1307MetfsX13), c3184_3187delCAAA(p.Gln1061AspfsX59) and c4127_4126delAT (p.Tyr1376LysfsX9), respectively, and all deletion mutations resulted in a premature stop codon. At the same time, we found c.3921_3924delAAAA and two c.3926_3930delAAAAG are located in AAAAG short tandem repeats, c3184_3187delCAAA is located in the CAAA interrupted direct repeats, and c4127_4128 del AT is located in the 5'-CCTGAACA-3', 3'-ACAAGTCC-5 palindromes (inverted repeats) of the APC gene. Furthermore, deletion mutations are mostly located at condon 1309. Conclusions: Though there were no novel mutations found as the pathogenic gene of FAP in this study, we found nucleotide sequence containing short tandem repeats and palindromes (inverted repeats), especially the 5 bp base deletion at codon 1309, are mutations in high incidence area in APC gene,.

Sentinel lymph Node mapping versus systematic pelvic lymphadenectomy on the prognosis for patients with intermediate-high-risk Endometrial Cancer confined to the uterus before surgery: trial protocol for a non-inferiority randomized controlled trial (SNE

Jun Guan,Yu Xue,Rong-yu Zang,Ji-hong Liu,Jian-qing Zhu,Ying Zheng,Bo Wang,Hua-ying Wang,Xiao-jun Chen 대한부인종양학회 2021 Journal of Gynecologic Oncology Vol.32 No.4

Background: Sentinel lymph node (SLN) mapping has been recommended as an alternative staging approach to lymphadenectomy for apparent uterine-confined endometrial cancer (EC). However, the prognostic value of SLN mapping alone instead of systematic lymphadenectomy on EC patients remains unclear. Methods: A multi-center, open label, non-inferiority randomized controlled trial has been designed to identify if SLN mapping alone is not inferior to pelvic lymphadenectomy on prognosis of patients with intermediate-high-risk EC clinically confined to uterus. Eligible patients will be 1:1 randomly assigned to accept SLN mapping or pelvic lymphadenectomy. The primary endpoint is the 2-year progression-free survival (PFS). The second points are the 5-year PFS, 5-year overall survival, surgery-related adverse events and life quality. A total of 780 patients will be enrolled from 6 hospitals in China within 3-year period and followed up for 5 years. Trial Registration: ClinicalTrials.gov Identifier: NCT04276532
