This paper presents plasma exchange(P.E) therapy in 8 cases of four types of immunic diseaes. The colony forming unit-T lymphocyte (TL-CFU), the symbol T-cell subsets with monoclone antibody (McAb), and the cisrculating immune complex (CIC)were examined before and after the therapy of P.E. and compared with the interelationship of each other. The experiments indicated that plasmapheresis may remove the CIC and noxious autoantibodies and regulation of the action of cellular immunity. All these functions are synthetic therapeutic effects. The indices of checkup on therapeutics were: TL-CFU, CIC and the ratio of T_H and T_S. After plasmaphersis, the ratio of CIC was lowered but the TL was higer than before (P

Objective To study the effect of active ingredients(saikosaponin) of bupleurum chinensis D C.on GABA of hippocampus of chronic kindling induced by pentylenetetrazol(PTZ) in rats.Methods Forty-eight healthy Sprague-Dawley rats were randomly divided into six groups with eight in each group: normal control(Group A), normal saline(NS) group(Group B),sodium valproate(VPA) group(Group C),group of large-dose saikosaponin(Group D),group of medium-dose saikosaponin(Group E),and group of small-dose saikosaponin(Group F).Except Group A to be controlled,the other groups were given different treatments when chronically kindled by PTZ.The process of the test lasted for 4 weeks.After 4 weeks' administration the brain tissues were sampled,sliced and stained by enzyme immunohistochemistry(EIH).The results were analyzed according to the positive cell population and gray value.Results The positive cell population of CA1,CA2 and DG in group B was significantly different from that in the other groups(P

AIM To investigate whether tubeimosides induce apoptosis in CNE-2Z. METHODS Growth inhibition by tubeimosides was measured using MTT assay. The effect of tubeimosides on apoptosis induction of CNE-2Z cell line was studied by the fluorescent microscopy, electronic microscopy, DNA agarose gel electrophoresis, flow cytometry analysis. Western blotting was performed for detecting the apoptosis-related gene. RESULTS The growth of CNE-2Z cells was inhibited obviously by tubeimosides. CNE-2Z cells showed typical apoptotic features observed by fluorescent microscopy, electronic microscopy. DNA fragmentation into multiples of low molecular weight DNA(180～200 bp) was detected by agarose gel electrophoresis of DNA; Sub-G 1 peak was found by flow cytometry analysis, and the apoptosis index was 58 0%. The expression of bcl-2, inhibitor of apoptosis, decreased apparently; while that of bax, inducer of apoptosis, increased notably at 1, 3, 5 h after the addition of tubeimosides. The cleavage of caspase-3 was noticed at 1, 3, 5 h after the treatment of tubeimosides. CONCLUSION Tubeimosides could induce the apoptosis of CNE-2Z cells. The induction of apoptotic by tubeimosides was closely associated with bcl-2, bax and caspase-3.

Objective To study the potential antidepressive-like effect of tetramethylpyrazine (TMP). Methods Forced-swimming and chronic mild stress (CMS) tests were performed to assess the antidepressant-like activity of TMP. Male Sprague-Dawley (SD) strain rats were divided into six matched groups (n= 13 or 14 in each group) based on their sucrose consumption:control, CMS, CMS + fluoxetine, and CMS + TMP groups. The rats except control were housed separately in different rooms, and the rat model of depression was established by exposing to an unpredictable sequence of stressors for 28 days; the rats in CMS + fluoxetine were exposed to CMS and received administration of FLU (2.0 mg· kg-1·d-1 ,ig) for 28 days; the rats in CMS + TMP groups were exposed to CMS and received administration of TMP (10,20,40 mg·kg-1·d-1 ,ig) , respectively, for 28 days. The rats in control group were given ordinary daily care and received ig administration of normal saline simultaneously. The body weight, food intake and fluid consumption were measured, and the behaviors were examined by open field during the duration of the stress procedure, and forced-swimming test was performed 1 day after last unpredictable stressor. Results Acute administration of TMP markedly decreased the duration of immobility during forced-swimming test((89.0 ±37.0)s vs (117.1 ±32. 1)s, P<0.05) . Chronic administration of TMP partially countered the effects of CMS on consumption of sucrose solution and locomotion and exploration behavior, and potently shortened the immobility time during forced-swimming test following CMS in rats. The results showed that long-term administration of TMP partially reversed the effects of CMS on the body weight gain,the consumption of sucrose solution,the squares crossing in open field test and the immobility time during forced-swimming test in rats ((91.9 ±31.5) vs (124.4±27.0)s,P<0.05).Conclusion TMP shows obvious antidepressant-like activity.

Objective To investigate the characteristics of homocysteine in patients with coronary heart disease (CHD) and the intervention effect of folic acid.Methods90 patients with coronary heart disease form internal medicine-cardiovascular department in the third affiliated Liwan hospital of Guangzhou Medical University from December 2015 to December 2016 as the study group.They were randomly divided into group A and group B, 45 patients in each group.The group A received routine treatment and Group B on the basis of conventional treatment plus folic acid.Another 90 healthy people who came to our hospital during the same period were selected as control group.The plasma homocysteine level of study group and control group were compared and plasma homocysteine level and angina status(frequency and duration of disease) of A and B group were compared before and after treatment.ResultsThe plasma homocysteine level of study group was significantly higher than that of the control group (P<0.05).After treatment, plasma homocysteine level,frequency and duration of disease of two groups were better than that of before treatment and B group was lower than that of A group(P<0.05).ConclusionThe results of plasma homocysteine levels can be used as an important basis for the clinical diagnosis of coronary heart disease and to determine its efficacy.
