Efficacy observation of acupuncture for dry eye syndrome of lung-yin deficiency pattern / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of combining two needling manipulations, Er Long Xi Zhu (two dragons playing with a pearl) and Guo Yan Re (heat produced to reach the eyes), in treating dry eye syndrome (DES) of lung-yin deficiency pattern. Methods: Fifty-six eligible DES patients of lung-yin deficiency were randomized into an observation group and a control group, with 28 cases in each group. Same acupoints were selected in the two groups: Cuanzhu (BL 2), Sizhukong (TE 23), Taiyang (EX-HN 5) and Fengchi (GB 20) were chosen as the major points and Feishu (BL 13) and Chize (LU 5) as the adjuvant. Er Long Xi Zhu and Guo Yan Re needling manipulations were applied in the observation group while twirling reinforcing manipulation was used in the control group. Treatment was conducted once per day in both groups, for two sets of 15 consecutive days at a 2-day interval. Changes in the symptom score, tear break-up time (BUT) and tear production were observed afterwards, and the clinical efficacy was also compared between the two groups. Results: The total effective rate was 92.8％ in the observation group, higher than 71.4％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the symptom score, tear BUT and tear production showed significant improvements in both groups (all P<0.05); the symptom score, BUT and tear production in the observation group were significantly different from those in the control group (all P<0.05). Conclusion: Given the same acupoint selection, combining Er Long Xi Zhu and Guo Yan Re needling manipulations can produce more significant clinical efficacy than twirling reinforcing manipulation in treating DES of lung-yin deficiency pattern.

Objective: To compare the clinical efficacy between 'warming-unblocking needling technique' and reinforcing method by twirling in treating knee osteoarthritis (KOA) due to deficiency of liver and kidney. Methods: A total of 72 patients with KOA were divided into a warming-unblocking group and a reinforcing group by complete randomized method, with 36 cases in each group. Xuehai (SP 10), Heding (EX-LE 2), Liangqiu (ST 34), Neixiyan (EX-LE 4), Xizhong (Extra), Dubi (ST 35), Yinlingquan (SP 9), Zusanli (ST 36) and Yanglingquan (GB 34) were the main points in both groups. Taichong (LR 3), Taixi (KI 3) and Sanyinjiao (SP 6) were the combined points. 'Warming-unblocking needling technique' was applied in the warming-unblocking group, and reinforcing method by twirling was applied in the reinforcing group. The treatments were performed once a day, 10 times as a treatment course, at a 2-day interval between two courses, for 3 courses in total. The scores of Western Ontario and McMaster Universities osteoarthritis index (WOMAC) in the two groups were observed before and after the treatment, and the clinical efficacy was compared. Results: After treatment, the total effective rate was 94.3％ in the warming-unblocking group and 87.9％ in the reinforcing group, and the difference between the two groups was statistically significant (P<0.05). The component scores of pain, stiffness and daily activities in WOMAC and total WOMAC scores in both groups decreased after treatment (all P<0.01). The component and total WOMAC scores in the warming-unblocking group were lower than those in the reinforcing group (P<0.05 or P<0.01). Conclusion:'Warming-unblocking needling technique' has significant efficacy than reinforcing method by twirling in treating KOA due to deficiency of liver and kidney. It can significantly improve pain, stiffness and daily functional activities of patients.

Host glial cell canceration induced by glioma stem cells in GFP/RFP dual fluorescence orthotopic glioma models in nude mice / 中华肿瘤杂志

<p><b>OBJECTIVE</b>During the process of tissue remodeling in human tumor transplantation models, the roles of the inoculated tumor cells and host tissue in tumor progression is still largely unknown. The aim of this study was to investigate the relationships and interactions between these two sides using GFP-RFP double fluorescence tracing technique.</p><p><b>METHODS</b>Red fluorescence protein (RFP) gene was stably transfected into glioma stem cell line SU3, then SU3-RFP cells were transplanted into the brain of athymic nude mice with green fluorescence protein (GFP) expression. After the intracerebral tumors were formed, the relationship and interaction between GFP cells and RFP cells were analyzed. Highly proliferative GFP cells were screened out, and monocloned with micro-pipetting. DNA content assay, chromosome banding and carcinogenicity test of the GFP cells were performed to observe the GFP cells' cancerous phenotype in nude mice.</p><p><b>RESULTS</b>In the transplantable tumor tissue, besides a great quantity of RFP cells, there were still a proportion of GFP cells and GFP/RFP fusion cells. The proportion of RFP cells, GFP cells and GFP/RFP cells were (88.99 ± 1.46)%, (5.59 ± 1.00)%, and (4.11 ± 1.020)%, respectively. Two monoclonal host GFP cells (H1 and H9) were cloned, which demonstrated the properties of immortality, loss of contact inhibition, and ultra-tetraploid when cultured in vitro. Both H1 and H9 cells expressed CNP, a specific marker of oligodendrocytes. The GFP cells also demonstrated 100% tumorigenic rate and high invasive properties in vivo.</p><p><b>CONCLUSIONS</b>In this glioma transplantation model, the transplanted tumor tissues contained not only transplanted glioma stem cells but also cancerous host GFP cells. Our findings offer important clues to further research on the relationships among different members in the tumor microenvironment.</p>

Incubation and application of transgenic green fluorescent nude mice in visualization studies on glioma tissue remodeling / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The primary reasons for local recurrence and therapeutic failure in the treatment of malignant gliomas are the invasion and interactions of tumor cells with surrounding normal brain cells. However, these tumor cells are hard to be visualized directly in histopathological preparations, or in experimental glioma models. Therefore, we developed an experimental human dual-color in vivo glioma model, which made tracking solitary invasive glioma cells possible, for the purpose of visualizing the interactions between red fluorescence labeled human glioma cells and host brain cells. This may offer references for further studying the roles of tumor microenvironment during glioma tissue remodeling.</p><p><b>METHODS</b>Transgenic female C57BL/6 mice expressing enhanced green fluorescent protein (EGFP) were crossed with male Balb/c nude mice. Then sib mating was allowed to occur continuously in order to establish an inbred nude mice strain with 50% of their offspring that are EGFP positive. Human glioma cell lines U87-MG and SU3 were transfected with red fluorescent protein (RFP) gene, and a rat C6 glioma cell line was stained directly with CM-DiI, to establish three glioma cell lines emitting red fluorescence (SU3-RFP, U87-RFP, and C6-CM-DiI). Red fluorescence tumor cells were inoculated via intra-cerebral injection into caudate nucleus of the EGFP nude mice. Tumor-bearing mice were sacrificed when their clinical symptoms appeared, and the whole brain was harvested and snap frozen for further analysis. Confocal laser scanning microscopy was performed to monitor the mutual interactions between tumor cells and host brain cells.</p><p><b>RESULTS</b>Almost all the essential tissues of the established EGFP athymic Balb/c nude mice, except hair and erythrocytes, fluoresced green under excitation using a blue light-emitting flashlight with a central peak of 470 nm, approximately 50% of the offsprings were nu/nu EGFP+. SU3-RFP, U87-RFP, and C6-CM-DiI almost 100% expressed red fluorescence under the fluorescence microscope. Under fluorescence microscopic view, RFP+ cells were observed growing wherever they arrived at, locating in the brain parenchyma, ventricles, and para-vascular region. The interactions between the transplanted tumor cells and host adjacent cells could be classified into three types: (1) interweaving; (2) mergence; and (3) fusion. Interweaving was observed in the early stage of tumor remodeling, in which both transplantable tumor cells and host cells were observed scattered in the tumor invading and spreading area without organic connections. Mergence was defined as mutual interactions between tumor cells and host stroma during tumorigenesis. Direct cell fusion between transplantable tumor cells and host cells could be observed occasionally.</p><p><b>CONCLUSIONS</b>This study showed that self-established EGFP athymic nude mice offered the possibility of visualizing tumorigenesis of human xenograft tumor, and the dual-color xenograft glioma model was of considerable utility in studying the process of tumor remodeling. Based on this platform, mutual interactions between glioma cells and host tissues could be observed directly to further elucidate the development of tumor microenvironment.</p>

Ultrastructural analysis of glioma stem cells-progenitors / 中华肿瘤杂志

<p><b>OBJECTIVE</b>It is well known that glioma stem cells-progenitors (GSCP) proliferate indefinitely and hardly differentiate in vitro, however, the reasons remain unknown. The aim of this study was to explore the ultrastructural basis of GSCP.</p><p><b>METHODS</b>GSCP, kept by our laboratory, were collected, embedded, and cut into ultrathin sections and observed under the transmission electron microscope.</p><p><b>RESULTS</b>A single GSCP usually had relatively well developed mitochondria, Golgi apparatuses, ribosomes, and undeveloped rough endoplasmic reticulum, but seldom lysosomes and no typical autophagosomes were found, and the nuclear-cytoplasmic ratio was high. The nuclei frequently contained huge amounts of euchromatin and a small quantity of heterochromatin, and in most nuclei there were only one nucleolus, however, two or more nucleoli were also common. Typical apoptotic cells could hardly be found in tumor-spheres, and between neighboring cells in tumor-spheres there were incompletely developed desmosomes or intermediate junction.</p><p><b>CONCLUSION</b>The ultrastructural features of glioma stem cells-progenitors showed that BTSCP were very primitive and the lack of autophagy and the underdevelopment of some other cellular organelles are probably the reasons for the differential inhibition of GSCPs.</p>

Expression of Human Interferon-λ1 and Interferon-ε Gene in WI-38 Cells and Comparison of Their Biological Activity / 中国生物工程杂志

The biological activities i. e. antineoplastic activities and antiviral activity of the two novel kinds of interferons: hIFN-λ1 and hIFN-ε were studied and compared. First the fusion expression vector: pcDNA3.1A-hIFN-λ1-His and pcDNA3.1A-hIFN-ε-His by PCR was constructed, then the two kinds of plasmids were transfected into WI-38 (human embryonic lung cells ) with liposome. And cytopathic effect (CPE) suppression test was used to study and compare the antiviral activities of rhIFNλ1-His and rhIFN-ε-His, meanwhile MTT assay was used to detect their antineoplastic activities. It was found that, antiproliferative activity and MxA protein induction shown by rhIFN-λ1-His is more powerful than of rhIFN-ε -His. The antiviral molecular mechanisms of both hIFN-λ1 and hIFN-ε are related to MxA. The foundation for further study on the bioactivities and mechanism of action of hIFN-λ1 and hIFN-ε was established.

Cellular Apoptosis of C6 Mouse Glioma Cells Induced by hING4 Mediated by Adenovirus / 中国生物工程杂志

The known members of inhibitor of growth (ING) gene family are considered as candidate tumor suppressor genes. ING4, a novel member of ING family, is recently reported to regulate brain tumour angiogenesis through transcriptional repression of NF-?B-responsive genes, induce G2/M arrest by the increased p21 expression in a p53-dependent manner, suppress the loss of contact inhibition and represses activation of the hypoxia inducible factor, which plays an important role in the progression of tumorigenesis. However, seldom studies about ING4 inducing tumor cells apoptosis were reported.The C6 cells (mouse glioma cells) were infected respectively with the blank adenovirus carrying GFP (Ad) and the recombinated Ad-hING4-His, then RT-PCR assay was used to detect the transcriptions of hING4, as well Western-blotting assay was ued to detect the expressions of hING4. The effects of hING4 expression upon C6 cells were observed, and the growth curve was drawed and tumor control rates were calculated. The C6 cells, which were affected by blank Ad and Ad-hING4-His, were respectively observed by LSCM (laser scan confocal microscope) and transmission electron microscope (TEM), detected by flow cytometry; and the genomic DNA of both groups were extracted and electrophoresised in agarose gel to examinate the DNA fragments. The results showed hING4 can significantly inhibit the growth of C6 cells by promoting the cell’s apoptosis, which probably is the first one to prove this property of ING4.The experimental and theoretical foundation for gene therapy for gliomas with ING4 in the future was established.
