1.Positively and reasonably clinical application of endoluminal stenting
Journal of Interventional Radiology 1994;0(03):-
The endoluminal stenting is popular for more than two decades,even in China,encouraging achievements also are getting around the recent dacade.Endoluminal stents are not only applicated for all kinds of vascular stenosis,and nonvascular stenosis such as biliary tract,esophagus,trachea etc,but also are utilized gradually in the interventional treatment of cerebral ischemia and hemorrage in the recent years,especially for aortic aneurysm.There would still have a long way to go in China for further development in basic research,standardized procedure,and normalized followed-up.The main target for all the interventional radiologists in the foreseen future is how to develop new stents with independent knowlege property right and to expand the stents usage reasonably.
2.Clinical study on acupuncture plus auricular point sticking for tension-type headache
Journal of Acupuncture and Tuina Science 2021;19(1):49-55
Objective: To observe the clinical efficacy of acupuncture plus auricular point sticking for tension-type headache (TTH). Methods: A total of 90 TTH patients were divided into an acupuncture group, an auricular point sticking group and an observation group by random number table method, with 30 cases in each group. Patients in the observation group received acupuncture plus auricular point sticking for treatment, while those in the acupuncture group only received acupuncture and those in the auricular point sticking group only received auricular point sticking for treatment. The headache attack frequency and the scores of visual analog scale (VAS), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were observed before treatment, after treatment and 3 months after treatment. The clinical efficacy was evaluated at the follow-up of 3 months after treatment. Results: At follow-up, there were significant differences in clinical efficacy among the three groups (P<0.01 or P<0.05), and the clinical efficacy ranking from high to low was the observation group, the acupuncture group and the auricular point sticking group. After treatment and at follow-up, the VAS score, headache attack frequency, SAS and SDS scores in the three groups were significantly lower than those before treatment (all P<0.01). The above four results in the observation group were lower than those in the acupuncture group and the auricular point sticking group at the same time point (all P<0.01); VAS score in the acupuncture group was lower than that in the auricular point sticking group (both P<0.05). At follow-up, the headache frequency in the acupuncture group was lower than that in the auricular point sticking group (P<0.05). Conclusion: Either using acupuncture and auricular point sticking together or separately can reduce the headache degree of TTH patients, reduce the number of headache attacks, and relieve anxiety and depression. The efficacy of acupuncture plus auricular point sticking is most significant.

The molecular characterization of self-antigens expressed by human malignancies that are capable of elicitation of anti-tumor immune responses in patients has been an active field in hematology, oncology, and tumor immunology. More than 2000 tumor antigens have been identified. These significant progresses have led to the renaissance of tumor immunology and studies on novel anti-tumor immunotherapies in lymphomas, other hematologic malignancies and tumors. However, despite of the progress in the identification of these self-tumor antigens, current antigen-specific immunotherapies for tumors are far less satisfactory than that expected, which reflects the urgent need to improve our understanding on the basic principles underlying the selection of these self-tumor antigens. In order to develop more effective antigen-specific anti-tumor immunotherapies and to monitor the responses to these immunotherapies in patients with lymphomas and other malignancies, many additional questions need to be addressed. In this brief review, the progress in the identification of tumor antigens in lymphomas and other malignancies was outlined and the new principles of self-tumor antigens and their significance for future immunotherapies to these malignancies were summarized.

Objective To investigate the effect of different doses of dexmedetomidine (DEX) on myocardial ischemia-reperfusion injury (MIRI) in rats.Methods Seventy-five SD male rats weighing between 250 and 300g were divided into sham group,MIRI group,small-dose DEX group,medium-dose DEX group and high-dose group according to the random number table,with 15 rats per group.Threading the left anterior descending coronary artery was done only in sham group,but the MIRI model was produced in the rest groups by ligation of the artery for 30 minutes followed by 120 minutes of reperfusion.Fifteen minutes before the ligation,small-,medium-and high-dose DEX groups were injected 2.5,5 and 10 μg · kg-1 · h-1 of DEX respectively until the end of reperfusion.Instead,an equal volume of normal saline was given in sham and MIRI groups.At the end of reperfusion,five rats in each group were used to determine the myocardial infarct size,and arterial blood samples and myocardial tissues from ten rats in each group were used to measure serum levels of interleukin-1β (IL-β) and serum tumor necrosis factor-α (TNF-α),expression of myocardial nuclear factor kappa B p65 (NF-κB p65) and change of myocardial pathomorphology.Results Myocardial infract size,degree of myocardial pathomorphology structure damage,serum levels of IL-1 β and TNF-αt and expression of myocardial NF-κB p65 in sham group were significantly lower in sham group than other groups (P < 0.05).Above mentioned parameters in small-,medium-and high-dose DEX groups were all significantly decreased compared to MIRI group (P < 0.05),and the decrease was most significant in medium-dose DEX group (P < 0.05).Conclusions DEX can attenuate the MIRI in rats and the possible mechanism is suppressing the release of NF-κB p65,which can reduce serum pro-inflammatory cytokines like TNF-α and IL-1β.And mediumdose DEX exhibits better protective effect.

To construct an immortalized rat astrocyte strain genetically modified by rat preprogalanin gene (IAST/GAL) and detect its galanin (GAL) expression and secretion, a cDNA fragment of rat GAL in plasmid of pBS KS(+)-GAL was inserted into eukaryotic expression vector pcDNA3.1 (+) by DNA recombinant technology, then the restriction enzyme digestion and DNA sequencing were carried out to evaluate the recombinant. The pcDNA3.1 (+)-GAL and pcDNA3.1 (+) construct were transfected into immortalized rat astrocyte strain (IAST) by lipofectamine and the population of cells which stably integrated the construct was selected with 600 microg/mL G418. Individual clones were screened and expanded into clonal cell strains. Detection of Neo gene was used to validate the success of the transfection. Immunocytochemical staining, RT-PCR and radioimmunoassay were used to detect the expression and secretion level of GAL. The recombinant had been successfully constructed by restriction enzyme digestion and DNA sequencing. Detection of Neo gene showed that the pcDNA3.1 (+)-GAL and pcDNA3.1 (+) have been successfully transfected into IAST. After selection by using G418, IAST/GAL and IAST/Neo cell strains were obtained. IAST/GAL, IAST/Neo and IAST were immunostained positively for GAL, but the GAL average optical density of IAST/GAL was significantly higher than that of IAST/Neo and IAST (P< 0.01). The level of GAL mRNA expression and the supernatant concentration of GAL in cultured IAST/GAL were significantly higher than those of IAST and IAST/Neo (P<0.01), but no significant differences were found between the IAST and IAST/Neo (P>0.05). It was concluded that IAST/GAL strain was constructed successfully and it might provide a basis for the further study of pain therapy.
