World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(6):1287-1293
This study was aimed to compare the difference of treatment on acute adjuvant arthritis (AA) by using dif-ferent energy densities withirradiation on ST36-Zusanli under the fixed wavelength (650 nm) by the semiconductor. Biological effect and traits of the laser irradiation were also studied. A total of 60 healthy male SD rats were random-ly divided into the normal control group, model group, low energy density group (61.89 J/cm2)and high energy density group (247.57 J/cm2). The Freund's complete adjuvant (FCA) was intradermallyinjected into rats' right hind paw to establish AA rat model. The treatment group was treated with 650nm semiconductor laser irradiation on ST36-Zu-sanli with the energy density of 61.89 J/cm2 and 247.57 J/cm2, respectively. The joint swelling degree, pain thresh-old, TNF-α and IL-1β level changes were observed on thefirst, third and fifthtreatment after modeling. The results showed that compared with the normal group, the joint swelling degree, pain threshold, TNF-α, and IL-1β were obvi-ously increased in the model group (P<0.05). After five times treatment, the semiconductor laser with low and high energy density had effect on acute inflammation. And the high energy density treatment effect had a better effect than the low energy density one (P<0.05). It was concluded that the energy density of 61.89 J/cm2 and 247.57 J/cm2 of semiconductor laser irradiation on ST36-Zusanli can relieve acute inflammatory pain and swelling caused by AA; re-duce the TNF-α and IL-1β concentration levels. Semiconductor laser irradiation had the characteristics of stimula-tion or inhibition, cumulative effect and parabola. Low energy density group obtained the best effect between the third and fifth treatment.

Chinese Journal of Radiology 2011;45(3):274-278
Objective To evaluate the clinical therapeutic effect with microspheres embolization for giant hepatocellular carcinoma(HCC). Methods A prospective study was performed for 156 HCC patients needed for TACE, then randomly signed them into group M (embolized by microspheres alone), group L (embolized by lipiodol alone) and group M + L (embolized by microspheres combined with lipiodol). TACE of group M was performed by 300-700 μm microspheres. Group L selected lipiodol alone to embolize. While group M + L were embolized by about 1/3-1/2 lipiodol of total embolized volume and then microspheres feeding individual tumor vessels. Stoped the procedure when caused terminal vessel blockade. Before and after therapy, patients'liver function, serum α-fetoprotein level (AFP), responses of tumor, complications related to embolization and survive rates of 180 days and 360 days were analyzed among three groups.Enumeration data such as survive rates and positive response were compared by χ2 test, while measurement data were analyzed by one-way classification. Results The positive response (CR + PR) of group M was 38.5% (20/52)and (CR + PR + SD)73. 1% (38/52). Survive rates of 180 days and 360 days were 88. 5% (46/52) and 82. 3% (43/52). While those of group L were 42. 3% (22/52) ,76.9% (40/52),86.5%(45/52), 75.0% (39/52) and group M + L were 55. 8 % (29/52), 88.5 % (46/52), 94. 2% (49/52),86. 5% (45/52). Significant difference of survival rates and total effective between group M + L and M,M + L and L was found(χ2 = 6. 27,6. 16, P < 0. 05). At the same time adverse responses of incidence and persis time such as febricity, nausea and vomit, hepatic pain were more lower in group M + L and group M.Three groups febricity rate were 63.4% (33/52), 86. 5% (45/52) and 69. 2% (36/52), nausea and vomit were 67.3 % (35/52) ,84. 6% (44/52) and 76. 9% (40/52), hepatic pain were 59. 6% (31/52), 86. 5 %(45/52), 73. 1% (38/52) (χ2 = 6.55, 6. 22, 6. 90, P < 0. 05). Conclusion Embolization with microspheres can get longer and more effective treatment. TACE with microspheres and lipiodol for embolizing HCC was more effective than with Microspheres or lipiodol alone.

The trace elements (Mn, Cu, Zn, Fe) andCalcium, Magnesium in aged person's serum oflong-life area and control area were determined. Itwas found that the contents of Manganese, cop-per, and Calcium of aged person's serum in long-life area were significantly higher than those incontrol area (Manganese and Calcium are essentialelements for health and antiaging, Copper is an es-sential trace element to health). In the long-lifearea the contents of six kinds of elements (Mn,Cu, Zn, Fe, Ca, Mg)in the serum have no signifi-cant distinction between the male aged and thefamle aged. In the long-life area the contents of sixkinds of elements (Mn, Cu, Zn, Fe, Ca, Mg )inaged (61~90) person's serum have no significantincrease or decrease with the increase of age.Judged from serum compositions, the agedperson's serum of the long-life area have a betterspectrum of elements. The relationship betweenthe elements in this experiment and antiaging effect was discussed.

Objective To explore the fluctuation of cytokine mRNA expression level in a novel T-cell-mediated immune hepatic fibrosis model induced by repeatedly injections of Concanavalin A in BALB/c mice. Methods BALB/c mice were divided into different groups. Model group mice were injected weekly up to 20 weeks with Concanavalin A (15mg/kg), via retro-orbital venous plexus under ether anesthesia. Normal control group mice were treated in the same manner weekly with normal saline. Twenty-four hours after Concanavalin A challenge at 1, 5, 12 and 20 week, 8 mice from each time were killed by cervical dislocation, repectively. The livers of different group were excised and fixed in 10% formalin for HE staining and Gomori Ag staining or frozen in optimal cutting temperature (O.C.T.) media in liquid nitrogen for immunohistochemical staining for CD4 +T or CD8 +T cell. After extracting total RNA from liver tissues, IL-2, IL-4, IL-10 and transforming factor ?1 messenger RNA were amplified by reverse transcription polymerase chain reaction. PCR products were electrophoresed on agrose containing ethidium bromide and visualized under ultraviolet light. Densitometric RT-PCR data were standardized with ?-actin signals. Results The histological change of HE staining and Gomori Ag staining indicated the fibrogenesis in model group mice. Immunohistochemical staining for CD4 + or CD8 + T cell indicated that the infiltrating lymphocytes in liver parenchyma were mainly CD4 +T lymphocytes. IL-2 mRNA expression level only increased after the first injection of Concanavalin A. The expression levels of IL-4, IL-10 and transforming growth factor ?1 mRNA significantly increased over the whole experiment period as compared with control group. Conclusions Repeated administration of Concanavalin A can induce T-cell-mediated immune hepatic fibrosis model in BALB/c mice. The expression levels of IL-4, 10 and TGF-?1 increase over the whole experiment period and may play an important role in creating mouse fibrotic model.

BACKGROUND:Currently, inhaled glucocorticoid is still the classic treatment for asthma. Adult stem cell transplantation has made significant progress in a variety of diseases, and it also provides new insights into the treatment of asthma.OBJECTIVE:To summarize the recent advances in the treatment of asthma with adipose-derived stem cells and related adult stem cells, and to discuss the therapeutic safety of adipose-derived stem cells and possible research directions in asthma therapy.METHODS:Relevant articles published from 2001 to 2016 were searched in PubMed, CBM, CNKI, and Wanfang databases. The keywords were (adipose-derived stem cells[All Fields]) OR (adipose stem cells[All Fields]) OR (adipose-derived mesenchymal stem cells[All Fields]) AND (asthma[All Fields]) in English and Chinese, respectively.RESULTS AND CONCLUSION:A total of 125 literatures were initially searched, and finally 54 representative papers were selected. Adipose-derived stem cells may reduce airway inflammation, airway hyperresponsiveness, ease collagen deposition and scar tissue formation, promote neovascularization, and reconstruct damaged airways in the mouse asthma model through immune regulation. It is necessary to understand its treatment mechanism of action deeply and comprehensively and carry out genomic analysis before introduction of adipose-derived stem cells as a conventional clinical treatment. In summary, adipose-derived stem cells may be a therapeutic potential for the treatment of airway allergic inflammatory diseases such as asthma.
