C3 glomerulopathy (C3G) is referred to disease which is out of control of complement activation,degradation and deposition,then leads to predominant C3 deposition in glomerular and glomerular injury.The study found that C3b amplification in the circulation and/or glomerular basement membrane were the key factors that cause immune disorders.Combined with clinical and experimental research,this paper mainly discusses the pathogenesis,clinical characteristics,and treatment of the disease.

Objective To investigate the feasibility and value of combined administration of rapamycin and low dose of cyclosporin A in kidney transplantation recipients. Methods Twenty-five recipients who received their kidney transplantations for 2 months to 10 years were transferred to a new immunosuppression regimen of combined administration of rapamycin,low dose of cyclosporin A and prednisone. During the clinical observation,the average serum trough level of cyclosporin A was maintained between 0.042 and 0.083 μmol/L,and the average serum trough level of rapamycin was controled to 4~8 μg/L. Meanwhile, the dosage of immunosuppressive drugs was adjusted properly according to the white blood cells counting,liver function,blood lipid level and clinical settings.Twenty-five kidney transplant recipients with usual immunosuppression regimen of cyclosporin A in combination with MMF and prednisone served as controls. Results Druing a follow-up period of 2 to 8 months,no acute rejection events were found in this group. All the recipients survived well with functional renal grafts. Two patients in the experimental group quitted during the follow-up. One was incurred to serious pulmonary infection diagnosed as cytomegalovirus infection,and another was sufferred from persistent unknown fever. Other main adverse effects included leucopenia, hyperlipemia and dental ulcer,similarly as control group. No significant abnormal liver function event was found in this group. Conclusions This new immunosuppression regimen of combined administration of rapamycin,low dose cyclosporin A and prednisone in kidney transplantation recipients could avoid or diminish the adverse and toxic effects of calcineurin inhibitors,mainlain well-functional allografts and not increase the incidence of severe untoward reactions. Meanwhile,the costs for taking medicine were also significantly reduced with this regimen. Therefore,it would be an ideal and optimal immunosuppressive maintainence regimen.

Objective To explore the correlation between cognitive ability and motor ability in stroke patients.Methods 30 stroke patients were assessed with the 3 m Timed Up and Go Test (TUG). The anticipated time by patients and the actual time were recorded, and their difference was caculated, named as the cognitive error. They were also assessed with Trail Making Test-Part A (TMT-A). The actual time of TUG, cognitive error and the time of TMT-A was compared among different groups of Brunnstrom stage of lower limb, and their correlation was analyzed. Results There was a significant difference between the actual time of TUG between Brunnstrom stage Ⅲ and Ⅴ (F=4.600, P<0.05). There was positive correlation between actual time of TUG and cognitive error(r=0.844, P<0.01), time of TMT-A and cognitive error(r=0.508, P<0.01), time of TMT-A and actual time of TUG (r=0.414, P<0.05). Conclusion Motor ability of stroke patients can be influenced by deficient attention and motor cognition.

Objective: To optimize the decolorization technology of activated carbon for the plant pigment in Bletilla striata polysaccharide.Methods: Using L 9 (3 4) orthogonal test with activated carbon as the decolorizer, the amount of activated carbon, decolorization temperature, decolorization liquid pH and decolorization time were investigated.The decolorization rate and polysaccharide retention rate were investigated.The decolorization rate and polysaccharide retention rate were taken as the indices.Results: The optimum decolorization technology was as follows: the amount of activated carbon was 1.0%, the decolorization temperature was 40 ℃, the pH value was 5 and the decolorization time was 30 min.Under those conditions, the decolorization rate of Bletilla striata polysaccharide was 91.3% and the retention rate of polysaccharide was 80.6%.Conclusion: The selected decolorization technology of activated carbon can make Bletilla striata polysaccharide get the best decolorizing effect.

Objective To investigate the effect of the serum of patients with hepatopulmonary syndrome on the myogenic differentiation,proliferation and migration of human lung fibroblasts.Methods The human lung fibroblasts were seeded in plates or flasks and randomly divided into 2 groups (n =31each) using a random number table:serum of patients with hepato-pulmonary syndrome group and serum of healthy volunteer group.The human lung fibroblasts were incubated in the DMEM culture medium containing 10% serum of patients with hepatopulmonary syndrome or in the DMEM culture medium containing 10% serum of healthy volunteers.At 24,48 and 72 h of incubation (T1-T3),the expression of smooth muscle-α-actin (SM-α-actin) and smooth muscle myosin heavy chain (SM-MHC) in human lung fibroblasts was determined by Western blot,the proliferation of the human lung fibroblasts was determined using 3H-TDR incorporation assay,and the migration of the human lung fibroblasts was determined by Transwell chamber assay.Results Compared with serum of healthy volunteer group,the expression of SM-α-actin and SM-MHC in human lung fibroblasts was significantly up-regulated at each time point,and the proliferation and migration of the cells were significantly enhanced at T2,3 in serum of patients with hepatopulmonary syndrome group (P<0.05).Compared with the value at T1,the expression of SM-α-actin and SM-MHC in human lung fibroblasts was significantly up-regulated,and the proliferation and migration of the cells were significantly enhanced at T2,3in serum of patients with hepatopulmonary syndrome group (P<0.05).Compared with the value at T2,the expression of SM-α-actin and SM-MHC in human lung fibroblasts was significantly up-regulated,and the proliferation and migration of the cells were significantly enhanced at T3 in serum of patients with hepatopulmonary syndrome group (P<0.05).Conclusion The serum of patients with hepatopulmonary syndrome can promote the myogenic differentiation,proliferation and migration of human lung fibroblasts.

Emodin is one of the main active ingredient of Rheum palmatum, and has anti-inflammatory, anti-bacterial, anti-viral and other effects. In recent years, it arouse concern since it has a significant anti-tumor effect with low toxicity. In this paper we mainly report the anti-cancer effects of emodin according to the studies of the past five years, including four parts such as inhibit tumor growth, inhibit migration and invasion, enhance the efficacy of combination therapy, increase chemosensitivity and attenuated side effects. We hope that our work may provide a reference for further study.
