中國地域廣袤,方言種類繁多,但是,信息科技飛速發展的今天,方言正在悄然流逝,人們 對地方方言和傳統文化漸漸漠視和遺忘,方言的喪失必將導致傳統文化的失根,所以對方言的重視 和保護很重要。作為一名語言文化研究愛好者,希望通過研究比較更多的方言來讓人們更了解自己 的語言。方言作為母語,在我們學習第二語言的時候會直接影響到第二語言的習得,不僅存在積極 的促進作用,也存在消極的阻礙作用,這就需要我們對兩種語言進行深刻的了解和多方面的比較研究。蘇州和合肥分別歸屬於吳語區和江淮官話區,雖然是兩種方言,但是從地理位置上看,相互接連,可見兩種方言之間一定存在一些共同特點和差別。筆者就蘇州和合肥的語言上進行比較研究,選擇展現入聲字的中古音在兩地的今讀,分別從方言的聲母和韻母的對比進行分析和解說,以此來 找出兩種方言之間的差異。 However, with the rapid development of information technology, dialects are slipping away. People are gradually ignoring and forgetting local dialects and traditional culture. The loss of dialects will surely lead to the loss of traditional culture. As a language and culture research enthusiast, I hope to make people know more about their own language by studying and comparing more dialects. As the mother tongue, dialect will directly affect the acquisition of the second language when we learn the second language, which not only has a positive role in promoting, but also has a negative role in hindering, which requires us to have a deep understanding of the two languages and a comprehensive comparative study. Suzhou and Hefei belong to the wu-speaking area and the jianghuai guanhua area respectively. Although they are two dialects, they are connected with each other from the geographical position. It can be seen that there must be some common characteristics and differences between the two dialects. Based on a comparative study of the languages of Suzhou and Hefei, the author chooses to present the modern pronunciation of the Chinese ancient pronunciation of rusheng characters in the two places, and analyzes and explains the differences between the initial and final vowels of the dialects respectively, so as to find out the differences between the two dialects.

<P><B>Summary</B></P> <P>Pro-inflammatory cytokines produced in the tumor microenvironment lead to eradication of anti-tumor immunity and enhanced tumor cell survival. In the current study, we identified tumor necrosis factor alpha (TNF-α) as a major factor triggering cancer cell immunosuppression against T cell surveillance via stabilization of programmed cell death-ligand 1 (PD-L1). We demonstrated that COP9 signalosome 5 (CSN5), induced by NF-κB p65, is required for TNF-α-mediated PD-L1 stabilization in cancer cells. CSN5 inhibits the ubiquitination and degradation of PD-L1. Inhibition of CSN5 by curcumin diminished cancer cell PD-L1 expression and sensitized cancer cells to anti-CTLA4 therapy.</P> <P><B>Highlights</B></P> <P> <UL> <LI> TNF-α stabilizes cancer cell PD-L1 in response to chronic inflammation </LI> <LI> Activation of NF-κB by TNF-α induces CSN5 expression leading to PD-L1 stabilization </LI> <LI> CSN5 enzyme activity controls T cell suppression via PD-L1 deubiquitination </LI> <LI> Destabilization of PD-L1 by CSN5 inhibitor curcumin benefits anti-CTLA4 therapy </LI> </UL> </P> <P><B>Graphical Abstract</B></P> <P>[DISPLAY OMISSION]</P>

Pharmacological blockade of cholesterol trafficking by cepharanthine in endothelial cells suppresses angiogenesis and tumor growth

<P><B>Abstract</B></P> <P>Cholesterol is an important modulator of membrane protein function and signaling in endothelial cells, thus making it an emerging target for anti-angiogenic agents. In this study, we employed a phenotypic screen that detects intracellular cholesterol distribution in endothelial cells (HUVEC) and identified 13 existing drugs as cholesterol trafficking inhibitors. Cepharanthine, an approved drug for anti-inflammatory and cancer management use, was amongst the candidates, which was selected for in-depth mechanistic studies to link cholesterol trafficking and angiogenesis. Cepharanthine inhibited the endolysosomal trafficking of free-cholesterol and low-density lipoprotein in HUVEC by binding to Niemann-Pick disease, type C1 (NPC1) protein and increasing the lysosomal pH. The blockade of cholesterol trafficking led to a cholesterol-dependent dissociation of mTOR from the lysosomes and inhibition of its downstream signaling. Cepharanthine inhibited angiogenesis in HUVEC and in zebrafish in a cholesterol-dependent manner. Furthermore, cepharanthine suppressed tumor growth in vivo by inhibiting angiogenesis and it enhanced the antitumor activity of the standard chemotherapy cisplatin in lung and breast cancer xenografts in mice. Altogether, these results strongly support the idea that cholesterol trafficking is a viable drug target for anti-angiogenesis and that the inhibitors identified among existing drugs, such as cepharanthine, could be potential anti-angiogenic and antitumor agents.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A phenotypic screen identified 13 existing drugs, including cepharanthine, as cholesterol trafficking inhibitors. </LI> <LI> Cepharanthine inhibited lysosomal cholesterol trafficking by binding to NPC1 protein and increasing the lysosomal pH. </LI> <LI> The blockade of cholesterol trafficking led to a cholesterol-dependent dissociation of mTOR from the lysosomes. </LI> <LI> Cepharanthine inhibited angiogenesis in HUVEC and in zebrafish in a cholesterol-dependent manner. </LI> <LI> Cepharanthine treatment enhanced the antitumor activity of cisplatin in lung and breast cancer xenografts in mice. </LI> </UL> </P>

Low Expression of Tyrosine-protein Phosphatase Nonreceptor Type 12 is Associated with Lymph Node Metastasis and Poor Prognosis in Operable Triple-negative Breast Cancer

Wu, Min-Qing,Hu, Pan,Gao, Jie,Wei, Wei-Dong,Xiao, Xiang-Sheng,Tang, Hai-Lin,Li, Xing,Ge, Qi-Dong,Jia, Wei-Hua,Liu, Ren-Bin,Xie, Xiao-Ming Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1

Background: Low tyrosine-protein phosphatase nonreceptor type 12 (PTPN12) expression may be associated with breast cancer growth, proliferation, and metastasis. However, the prognostic value of PTPN12 in breast cancer has not been clearly identified. Patients and Methods: 51 triple-negative breast cancer (TNBC) patients and 83 non-TNBC patients with a histopathology diagnosis from October 2001 to September 2006 were included in this study. Immunohistochemical staining for PTPN12 on tissue microarrays was conducted. Results: High PTPN12 expression was seen in 39.2% of TNBC and 60.2 % of non-TNBC cases. Low PTPN12 expression was associated with lymph node status (p = 0.002) and distant metastatic relapse (p = 0.002) in TNBC patients. Similarly, low PTPN12 expression in non-TNBC patients was significantly correlated with lymph node status (p = 0.002), stage (p = 0.002) and distant metastatic relapse (p = 0.039). The high PTPN12 expression group was associated with longer DFS and OS compared with low PTPN12 expression group only in TNBC cases (p = 0.005, p = 0.015), according to univariate Cox regression analysis. Conclusion: These findings provide evidence that low expression of PTPN12 is associated with worse prognosis and may be used as a potential prognostic biomarker in TNBC patients.

Expression of Lamininγ2 in Extrahepatic Cholangiocarcinoma Tissues and its Influence on Tumor Invasion and Metastasis

Li, Yong,Li, Da-Jiang,Chen, Jian,Liu, Wei,Li, Jian-Wei,Jiang, Peng,Zhao, Xin,Guo, Fei,Li, Xiao-Wu,Wang, Shu-Guang Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.5

Objective: To explore the expression of $laminin{\gamma}2$ in extrahepatic cholangiocarcinoma (EHCC) tissues and its influence on tumor invasion and metastasis. Materials and Methods: Paraffin embedding samples of cancer, para-cancer, lymph node metastatic and hepatic metastatic tissues from 79 patients undergoing EHCC resection were collected. Expression of $laminin{\gamma}2$ was detected by immunohistochemistry and its relationship with clinical pathological characteristics and the prognosis of EHCC patients were analyzed. Results: $Laminin{\gamma}2$ showed negative staining in para-cancer tissues, but demonstrated a 51.9% (41/79) positive expression rate in extracellular matrix (ECM) or cytoplasm of EHCC tissues. In lymph node metastatic and distant metastatic nidi, expression of $laminin{\gamma}2$ was significantly higher than in the primary nidi (${\chi}^2=7.4173$, P=0.0065; ${\chi}^2=4.0077$, P=0.0453). The expression was in obvious association with lymph node metastasis (P<0.01), but had no relevance with age, gender, tumor location, tumor stage, differentiation and distant metastasis in ECM (P>0.05), whereas it was in marked connection with lymph node and distant metastasis (P<0.05 or P<0.01), but had no relationship with age, gender, tumor location, tumor stage and differentiation in cytoplasm (P>0.05). However, the median survival time and median recurrent period of patients with positive expression of $laminin{\gamma}2$ in both cytoplasm and ECM of tumor cells, only in ECM and only in cytoplasm, were evidently lower than with negative expression of $laminin{\gamma}2$ in RCM and cytoplasm (P<0.05 or P<0.01). Further Cox regression analysis showed that the positive expression of $laminin{\gamma}2$ and the tumor differentiation were independent risk factors influencing the prognosis of EHCC patients. Conclusions: Abnormal expression of $laminin{\gamma}2$ may be closely associated with invasion and metastasis of tumor cells, and thus a potential molecular marker for prognosis of EHCC patients.

Application of Joint Detection of AFP, CA19-9, CA125 and CEA in Identification and Diagnosis of Cholangiocarcinoma

Li, Yong,Li, Da-Jiang,Chen, Jian,Liu, Wei,Li, Jian-Wei,Jiang, Peng,Zhao, Xin,Guo, Fei,Li, Xiao-Wu,Wang, Shu-Guang Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.8

Objective: To explore the application of joint detection of serum AFP, CA19-9, CA125 and CEA in identification and diagnosis of cholangiocarcinoma (CC). Materials and Methods: The levels of serum AFP, CA19-9, CA125 and CEA of both 30 patients with CC and 30 patients with hepatocellular carcinoma (HCC) were assessed. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic effects of single and joint detection of those 4 kinds of tumor markers for CC. Results: The levels of serum CA19-9, CA125 and CEA in CC patients were higher than that in HCC patients,whereas that of serum AFP was significantly lower s. The area under ROC curve of single detection of serum AFP, CA19-9, CA125 and CEA were 0.05, 0.86, 0.84 and 0.83, with the optimal cutoff values of 15.4 ng/ml, 125.1 U/ml, 95.7 U/ml and 25.9 ng/ml, correspondingly, and the percentage correct single diagnosis was <79%. With joint detection, the diagnostic effect of combined AFP, CA19-9, CA125 and CEA was the highest, with an area under the ROC curve of 0.94 (95%CI 0.88~0.99). Conclusions: Single detection of serum CA19-9, CA125 and EA is not meaningful. The sensitivity, specificity, the rate of correct diagnosis and the area under ROC curve of joint detection of AFP, CA19-9, CA125 and CEA are highest, indicating that the joint detection of these 4 tumor markers is of great importance in the diagnosis of CC.

Li Xiying,Li Xiaojuan,Wang Xian,Yin Xuan,Li Shanshan,Wu Junyi,Ren Xiumei,Zhang Wei,Mi Yiqun,Xu Shifen 한국한의학연구원 2023 Integrative Medicine Research Vol.12 No.3

Background: We conducted this randomized controlled trial (RCT) to evaluate the effectiveness and safety of moxibustion at Sanyinjiao (SP6) acupoint for treatment of negative mood and sleep quality in healthcare workers during the 2019 coronavirus disease (COVID-19). Methods: A total of 180 participants were divided in a 1:1 ratio into two groups, the treatment group (for moxibustion) and the control group (for no treatment). The treatment group had a 30-minute moxibustion therapy once a day for two weeks, followed by a two-week follow-up. The Hamilton Anxiety Scale (HAMA) was used to assess the degree of the participants' anxiety, and the Patient Health Questionnaire-9 (PHQ-9) was utilized to examine their depressed condition. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to measure the level of burnout among healthcare workers. To determine the severity of insomnia, the Sleep Dysfunction Rating Scale (SDRS) was utilized. At baseline, week 2, and week 4, all scales were evaluated. Results: Compared to the control group, The treatment group improved more significantly in the HAMA at week 2 (MD = -19.01, 95% CI: -21.89 to -16.14; P<0.001) and at week 4 follow-up visits (MD = -8.96, 95% CI: -11.19 to -6.73; P<0.001). A subgroup study of HAMA scores revealed that position and education had significant impact on treatment effectiveness. During the 2-week intervention period, the treatment group showed more significant improvements in depressive symptoms measured by PHQ-9 (13.00±2.41 vs. 15.60±3.65; P<0.001), work burnout symptoms measured by MBI-GS (MD = -11.88, 95% CI, -15.73 to -8.03; P<0.001), and insomnia symptoms measured by SDRS (MD = -2.45, 95% CI, -4.24 to -0.66; P<0.01). There were no significant adverse effects reported. Conclusion: Moxibustion at SP6 may be an effective treatment to improve anxiety, depression, sleep quality, and quality of life for healthcare workers during COVID-19.

Li, Wei,Zheng, Chang-Ji,Sun, Liang-Peng,Song, Ming-Xia,Wu, Yan,Li, Yin-Jing,Liu, Yi,Piao, Hu-Ri 대한약학회 2014 Archives of Pharmacal Research Vol.37 No.7

A series of arylhydrazone derivatives bearing a rhodanine moiety have been synthesized, characterized, and evaluated as antibacterial agents. Some of these compounds showed potent antibacterial activities against several different strains of Gram-positive bacteria, including multidrug-resistant clinical isolates. Of the compounds tested, IIk and IIIk were identified as the most effective, with minimum inhibitory concentration values of $2-4{\mu}g/mL$ against multidrug-resistant Gram-positive organisms, including methicillin-resistant and quinolone-resistant Staphylococcus aureus. None of the compounds exhibited any activity against the Gram-negative bacteria Escherichia coli 1356 at $64{\mu}g/mL$.

Li Juanfei,Wu Lei,Ma Mingyu,Song Ruifeng,Dong Chunhui,Wei Junfang,Li Jinsheng,Wang Xiaoqiang,Li Mingya 한국물리학회 2023 Current Applied Physics Vol.46 No.-

La0.7Sr0.3MnO3 (LSMO)/LaNiO3 (LNO) thin films were deposited successively on Si single crystal by the sol-gel method. The bipolar resistive switching (RS) behavior was studied in Al/LSMO/LNO devices. Obvious current hysteresis was observed, the set (reset) voltage and resistance ratio were modulated by the annealing temperature of LSMO thin films. At the annealing temperature of 750 ◦C, good endurance and retention performance were obtained in the memory device. According to the fitting results of I–V curves, based on Schottky emission model, the conduction mechanisms of Al/LSMO/LNO devices were discussed. Our results may give a valuable insight on developing perovskite-type rare earth manganese oxide.

MANAGING INNOVATION PERFORMANCE: A SERVICE-DOMINANT LOGIC VIEW

Li-Wei Wu,Chung-Yu Wang,Ya-Ting Wu 글로벌지식마케팅경영학회 2014 Global Marketing Conference Vol.2014 No.7

Partnerships have become an important research topic. However, the amount of empirical attention devoted to determining how firms intensively co-produce with alliance partners to improve their innovation performance is lacking. In response to the growing importance of co-production in the partnerships, this study addresses how firms integrate their alliance partners as co-creators into the innovation process. Specifically, this study not only integrates the three dimensions of social capital and examines their separate effects on co-production but also incorporates the roles of absorptive capacity and self-efficacy and investigates their influences on innovation. That is, co-production may operate through absorptive capacity and self-efficacy to increase innovation because knowledge is exchanged and utilized and firms are willing to select challenging goals and remain firmly committed to fulfill them within the network. The proposed model is tested with a structural equation model(SEM). Findings indicate positive relationships between social capital and co-production. Moreover, co-production has positive effects on innovation, absorptive capacity, and self-efficacy. Absorptive capacity and self-efficacy enhance innovation. As such, we suggest that co-production should be considered explicitly in the management of a partnership and should be developed through mentioned above platform, encouraging and enabling both parties to work together for the implementation of innovation.
