Objective To investigate the effect of splenectomy on peripheral lymphocyte apoptosis and CD4+ CD25+ Treg cells in rat with heart transplantation. Methods Abdominal heterotopic heart transplantation was performed from Wistar (donors) to SD (recipients) rats. Splenectomy was done at the same time in recipients (heart graft splenectomy group), non-splenectomy recipients (heart graft group), single splenectomy in SD rats (spleneetomy group), and SD rats (no operation) were designed as the control group. The transplanted hearts and peripheral blood in each group were collected on the 1st, 3rd, 5th and 7th day after operation. Histopathological and ultrastructural changes in transplanted hearts were observed by microscope and electronic microscope. Apoptosis rate of peripheral lymphocytes and CD4+ CD25+ Treg cells were measured by flow cytometry. The expression of Foxp3 mRNA in CD4+ CD25+ Treg cells was detected by RT-PCR, and survival time of the transplanted hearts was recorded. Results The survival time of the transplanted hearts in heart graft splenectomy group was 17.63±4.54 days, significantly longer than that in heart graft group (7.47±2.24 days) (P<0.05). The transplanted hearts in heart graft group were swelling, hard, dark, with interstitial edema, hemorrhage, diffuse infiltration of inflammatory cells, necrosis and cytolysis of a lot of myocardial cells, blurred cross striations; The transplanted hearts in heart graft splenectomy group were soft, red, partially gray white, with focal edema of subepicardial cells,infiltration of inflammatory cells, intact myocardial cell structure, and clear cross striations; Compared to heart graft group, the ultrastructural changes of transplanted hearts in heart graft splenectomy group were lighter significantly. On the 5th and 7th day after operation, apoptosis of peripheral lymphocytes in heart graft splenectomy group was (7.62±2.15)% and (9.41±3.82)% respectively, significantly higher than in heart graft group (both P<0.05). On the 3rd, 5 th and 7th day after operation, the number of CD4+ CD25+ Treg cells in heart graft splenectomy group was more (all P<0.01), and the expression level of Foxp3 mRNA higher than in heart graft group. Conclusion Splenectomy can increase apoptosis rate of peripheral blood lymphocytes and the number of regulatory T lymphocytes, and up-regulate the Foxp3 mRNA regulation in rats with heart transplantation, which has a negative correlation with pathological changes of transplanted hearts.

In the treatment of 12 patients with facial paralysis in the second trimester of pregnancy by puncturing Yifeng (TE 17), Yangbai (GB 14), Yingxiang (LI 20), Chengjiang (CV 24), Jiache (ST 6), Dicang (ST 4), Cuanzhu (BL 2), Heliao (LI 19) and others on the sick side plus TDP radiation and massaging on the affected face. Eleven cases were cured and one case was remarkably effective after 20 treatments.

To observe the clinical efficacy and safety of bicyclol and polyene phosphatidylcholine in the treatment of liver injury induced by hyperthyroidism. Methods: Totally 112 cases of hyperthyroidism patients were randomly divided into two groups, and both groups were treated with antithyroid drug methimazole. The 56 patients in the treatment group were orally treated with bicyclol, and the other 56 patients in the control group received polyene phosphatidylcholine capsules orally. The changes of liver func-tion were compared before and after the 4-week treatment, including the level of alanine aminotransferase (ALT), aspartate amin-otransferase ( AST) , total bilirubin ( TBIL) and alkaline phosphatase ( ALP) . The efficacy and adverse reactions were also observed. Results:There was no difference in the levels of ALT, AST, TBIL and ALP in both groups before the treatment (P>0. 05), while the levels were all decreased significantly in both groups after the treatment (P<0. 05). Compared with those of the control group, ALT and AST levels of the treatment group were decreased significantly after the treatment (P<0. 05), and the total effective rate of the treatment group was higher than that of the control group with statistical significance (P <0.05), while no statistically significant difference was shown in the levels of TBIL and ALP (P>0. 05). No drug-related adverse events were shown during the treatment. Conclusion:Bicyclol is effective and reliable in the treatment of liver injury induced by hyperthyroidism, and the clinical efficacy is remarkable when compared with that of polyene phosphatidylcholine.

OBJECTIVETo observe the effect of catgut implantation at acupoint on the content of tumor necrosis factor alpha (TNF-alpha), and to explore its mechanism for treatment of ankylosing spondylitis (AS).

METHODSSeventy-four AS patients were randomly assigned to the observation group and the control group by digit random table, 37 in each group. Patients in the control group took Sulfasalazine Enteric-coated Tablet (SECT), 0.5 g each time, three times daily for 3 months. Those in the observation group additionally received catgut implantation at acupoint for 3 months. Changes of visual analogue scale (VAS), Schober test, pillow wall distance, thoracic activity, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), and TNF-alpha were compared after 3 months of treatment.

RESULTSThere was obvious change in VAS, Schober test, pillow wall distance, thoracic activity, ESR, CRP, and TNF-alpha after treatment in the both groups, showing statistical difference when compared with before treatment (P < 0.05, P < 0.01). The aforesaid indices were obviously improved after treatment in the observation group (P < 0.05, P < 0.01).

CONCLUSIONCatgut implantation at acupoint, as an assistant therapy, could significantly improve clinical symptoms and signs, decrease the level of TNF-alpha, and its effect was superior to that of oral SECT administration alone.
