HBEGF up-regulate expression level of PD-L1 in glioblastoma cells partly through LIF / 中国药理学通报

Aim To investigate the mechanism of heparin-binding epidermal growth factor (HBEGF) in upregulating the expression of programmed death ligand 1 (PD-L1) in glioma cells by regulating leukemia inhibitory factor (LIF). Methods Pearson analysis was used to analyze the correlation between HBEGF, LIF and PD-L1 mRNA in primary gliomas, U251 and U87 cells were treated with HBEGF neutralizing antibody and HBEGF was added after HBEGF knockout, the mRNA and protein levels of LIF and PD-L1 were detected by real-time fluorescence quantitative PCR (RT-qPCR) and Western blot, HBEGF knockout cells were added with LIF neutralizing antibody on the basis of adding HBEGF, and the levels of PD-L1 mRNA and protein were detected. Results Pearson analysis showed that HBEGF, LIF, and PD-L1 mRNA were positively correlated (P < 0.05). After adding HBEGF neutralizing antibody to U251 and U87 cells, the mRNA and protein levels of LIF and PD-L1 gradually decreased with cell passage (P < 0.05). After HBEGF knockout, the mRNA and protein levels of LIF and PD-L1 decreased (P < 0.05), and the mRNA and protein levels of LIF and PD-L1 increased after HBEGF was added (P < 0.05). In HBEGF knockout cell lines, the levels of PD-L1 mRNA and protein were up-regulated after HBEGF was added (P<0.05), and the levels of PD-L1 mRNA and protein was down-regulated by LIF neutralizing antibody (P < 0.05). Conclusion The partial induction of LIF by HBEGF in glioblastoma is an intermediate process for HBEGF to maintain PD-L1 expression.

Discussion on the needling technique with filiform needle in acupuncture-moxibustion teaching materials in the Republic of China / 中国针灸

Through collecting the literature data of the needling technique with filiform needle in 20 acupuncture-moxibustion teaching materials in the Republic of China， the manipulation techniques with filiform needle were analyzed, such as the technique of needle insertion, the technique of reinforcing and reducing, and the management of acupuncture abnormal conditions, as well as manual techniques and analgesics methods. It is found that the era of the Republic of China was the transition period of traditional acupuncture techniques to the modern ones in acupuncture-moxibustion teaching materials, in which, the twirling technique was predominated in the technique of needle insertion. In that period, the insertion technique of tube needle had been introduced and simplified, the theory and method of the new-style technique of reinforcing and reducing were emerged and the types of acupuncture abnormal conditions recorded in the teaching materials were different from those at present. Additionally, the applicable manipulation had not been specified nationally. There were the highly influential teaching materials, i.e. , and . The acupuncture-moxibustion teaching materials in the Republic of China has been influenced by the transition of acupuncture-moxibustion education modes, the introduction of Chinese-translation version of Japanese acupuncture-moxibustion books, the academic thoughts of acupuncture masters and the manufacturing process of needle devices.

Summary and core technique on the origin and evolution of reinforcing-reducing manipulation achieved by lifting and thrusting the needle / 中国针灸

By analyzing the evolution of reinforcing-reducing manipulation achieved by lifting and thrusting the needle recorded in ancient literature of traditional Chinese medicine, it is found that the main contents of reinforcing-reducing manipulation by lifting and thrusting the needle include manipulating speed change, manual amplitude, insertion layer, gender, the direction to the acupuncture receiver, forenoon and afternoon and relevant quantity. Among them, gender, the direction to the acupuncture receiver, forenoon and afternoon and relevant quantity are the unnecessary parameters, while the manipulating speed change, manual amplitude and insertion layer are the indispensable parameters. The manipulating speed change is the core of the necessary parameters for the reinforcing-reducing manipulation achieved by lifting and thrusting the needle. Combined with the manual amplitude, the manipulating speed of needle determines the volume of needling stimulation. The insertion layer is decided on the base of the clinical demand. In the core technique of reinforcing-reducing manipulation by lifting and thrusting the needle, the reinforcing is achieved by thrusting the needle forcefully and quickly and then lifting the needle body slowly and evenly back to the original layer. The reducing is achieved by lifting the needle forcefully and quickly and then thrusting the needle body slowly and evenly back to the original layer. The manipulating speed and manual amplitude of needling are the parameters to quantize acupuncture manipulation. In association with the acupuncture effects in human body, these parameters contribute to the interpretation of the dose-effect relationship of acupuncture and the improvement of clinical effects.

Study on Response of TRPV1 Sensitive Neurons in Spinal Cord under Moxibustion of Different Temperatures / 中国中医药信息杂志

Objective To observe the response of TRPV1 sensitive neurons in spinal cord under moxibustion of different temperatures in "Zusanli". Methods Totally 40 healthy male SD rats were chosen and stimulated with moxibustion at "Zusanli" in 41 ℃, 45 ℃ and 49 ℃. Extracellular recording techniques of glass microelectrode was used in the rats' L4spinal cord neurons. Capsaicin vehicle and solution was injected into the rats through "Zusanli" to filter the sensitive neuron to TRPV1. The response of sensitive neurons to TRPV1 in spinal cord under moxibustion of three different temperatures was recorded and compared. Results The TRPV1 sensitive neurons responded to all the three temperatures. Viewing from the nature of the responding neurons, the neuron in 45 ℃ and 49 ℃ mainly performed in agitation, while the number of agitated and inhibitory neurons appeared same in 41 ℃. Viewing from the character of the responding neurons, different temperatures correspond to differential discharge frequency: 41 ℃was (8.26±2.14) spikes/s, 45 ℃ was (4.69±2.61) spikes/s, 49 ℃ was (10.66±5.97) spikes/s. Viewing from the change of discharge frequency, the neurons in 41 ℃ was found without obvious change, while the neurons in 45 ℃and 49 ℃ discharge frequency apparently increased (P<0.01). Conclusion Sensitive neurons in TRPV1 in spinal cord can response to 41 ℃, 45 ℃ and 49 ℃, whose character, nature and degree are related to the temperature gradient.

Evaluation of TAZ expression and its effect on tumor invasion and metastasis in human glioma

OBJECTIVES@#To evaluate the expression of TAZ and its role in tumor invasion and metastasis in human glioma.@*METHODS@#The expression of TAZ protein was measured in 48 samples of surgically resected human glioma and 13 samples of normal brain tissues using immunohistochemistry. TAZ was knocked down by a retrovirus-mediated TAZ shRNA in a glioma cell line, SNB19. Transwell cell migration and invasion assays were used to determine migration and invasion of SNB19 cells.@*RESULTS@#The positive expression rate of TAZ protein in glioma tissues was significantly higher than that in normal brain tissues (79.2% vs. 15.4%, P<0.001). Furthermore, clinical analysis suggested that the positive expression rate of TAZ protein in poorly differentiated tumor tissues was significantly higher as compared with that in well differentiated tissues (96.0% vs. 60.9%, P<0.01). TAZ was significantly knocked down by TAZ shRNA (P<0.001), and TAZ knockdown significantly reduced cell migration and invasion (P<0.01, respectively) in SNB19 cells.@*CONCLUSIONS@#TAZ protein overexpression is observed in human glioma and its elevated expression is significantly correlated with poor differentiation. TAZ knockdown prominently reduces cell migration and invasion in SNB19 cells, suggesting that TAZ may play a key role in the initiation and progression of human glioma.

Comparison of migration characteristics of MSCs in different assay systems / 中国实验血液学杂志

The aim of this study was to explore the difference of MSC migration mediated by SDF-1/CXCR4 axis through Boyden chamber in vitro migration assay. The SDF-1 density-dependence of MSC migration was observed. Subsequently, the effects of different blocking agents on hSDF-MSC migration were observed after MSC were treated with 50 nmol/L wortmannin, 10 micromol/L LY294002, 50 micromol/L PD98059, 10 micromol/L U73122, 126 micromol/L AMD3100 and 50 nmol/L verapamil respectively. The results showed the efficiency of MSC migration increased gradually with the increasing of hSDF-1 density. And after MSCs treatment with 50 nmol/L wortmannin, 10 micromol/L LY294002, 50 micromol/L PD98059, 10 micromol/L U73122 and 126 micromol/L AMD3100 respectively, the ability of MSC migration decreased. The ability of MSCs migration obviously decreased when MSCs were treated with U73122, AMD3100. It is concluded that the SDF-1/CXCR4-mediated MSC migration may be related to mitogen-activated protein kinase (MAPK), phosphatidylinositol phospholipase C (PI-PLC) and protein kinase (PKC) signal pathways.
