In the experiment, there were no significant differences between the one-fold or ten-fold dosage groups and the normal control group. Gene Gob-5 expression in five-fold dosage was significantly lower than that in the normal control group. Conclusion Fengxiaofang has the effect of lowering the expression of gene Gob-5 which maybe related to the potency on asthmatic disease.

Objective To study the expression levels of N-terminal pro-brain natriuretic peptide (NT-proBNP),serum albumin of Kawasaki' s disease (KD),incomplete Kawasaki' s disease (IKD),and children whose fever were unexplained and to explore the clinical significance of the levels of NT-proBNP and serum albumin in the early diagnosis of IKD.Methods The levels of NT-proBNP of 246 cases of KD (KD group),61 cases of IKD (IKD group) and 301 cases of children with unexplained fever (fever group)were measured by the enzyme-linked fluorescence analysis (ELFA) at the day of admission,meanwhile,the levels of albumin were tested in KD,and IKD children were underwent ECG and echocardiography.Based on the test results,patients were further divided into the group with cardiovascular damage and the group without cardiovascular damage.SPSS 19.0 was used for statistical analysis.The t test was used to compare the parameters between each group,the variance analysis and association analysis were carried out with Pearson's correlation analysis.The ROC curve analysis was done to identify the cardiovascular damage threshold.Results ① The level of plasma NT-proBNP of the KD group,the IKD group was significantly h igher than the fever group [(789.1±4.7) ng/L,(824.8±4.4) ng/L vs (92.5±2.3) ng/L,F=230.736,all P＜0.05];② The level of albumin of the KD group and the IKD group was significantly lower than that of the fever group [(33.9±2.8) g/L,(33.8±3.1) g/L vs (40.8±3.6) g/L,F=355.648,all P＜0.05]; ③ The levels of NT-proBNPs between the cardiovascular damage group and the groups without cardiovascular damage among the KD group,and those of the IKD groups were compared.In the KD group,the NT-proBNPs level of the two subgroups was (2948±3) g/L (n=103) vs (305±3) g/L,n=143; while in the IKD group,the NT-proBNPs of the two subgroups was (1454±4) g/L (n=38) vs (323±4) g/L (n=23).The dif-ferences were statistically significant (t=16.464,4.356,all P＜0.05).④ The plasma NT-proBNP level higher than 933.5 ng/L was identify as the indicator for cardiovascular damage in both KD and IKD children.Its sensi-tivity was 88.1％,and its specificity was 89％.⑤ When the level of NT-proBNP was higher than 250 ng/L,the sensitivity for diagnosis in the KD,the IKD was 80.9％,85.2％ respec-tively,and the specificity was 85.7％.When the level of NT-proBNP was higher than 250 ng/L and that of albumin was lower than 35 g/L,the sensitivity for diagnosis of KD,IKD was 67.5％,70.5％ respectively,the specificity was 99.7％.Conclusion The level of plasma NT-proBNP (＞250 ng/L) accompanied by decreased albumin (＜35 g/L) may be specific markers for early diagnosis of IKD.In addition,the level of NT-proBNP ≥933.5 ng/L can be used as a diagnostic threshold,which has good sensitivity and specificity for identifica-tion of cardiovascular damage in the KD and IKD in children.

BACKGROUND: the development of magnetic separation technique,it is feasibility to in vitro sort and amplify CD4+CD25+Treg cells for transplantation; however,the application dosage and immune tolerance have been less reported yet.OBJECTIVE: To investigate dose-effect relationship of CD4+CD25+Treg cells during allograft transplantation.METHODS: SD rats which were considered as the donors and Wistar rats as receptors were used to establish allograff kidney transplantation models.CD4+CD25+Treg cells were separated from splenic cells of Wistar rats and induced phenotype of donor antigenic specificity in vitro.According to the quantities of CD4+CD25+Treg cells injecting through tail vein during the operation of allograft kidney transplantation,models were rolled into four experiment groups: group 1(2×105),group 2(5×105),group 3(1×106),and group 4(2×106).The models out injection were considered as controls.Survival status of kidney was detected at day 15 postoperatively; creatinine level and pathological changes were detected at days 4,9 and 15 according to Banff Schema diagnostic standard; semi-quantitative scores were measured Watanabe technique.RESULTS AND CONCLUSION: The death rate was the highest in control group(83.3%),and then group 1(66.7%),group 4(58.3%),and group 2(33.3%); but rats in the group 3 were all survival.Creatinine level in experimental groups was significantly less than control group at days 4,9,and 15 postoperatively(P<0.05,P<0.01); the creatinine levels in the group1 and group 2 were significantly greater than in the group 3 and group 4 at days 9 and 15 postoperatively(P<0.05),Semi-quantitative scores demonstrated that there was no significant difference between group 2 and group 1; but the scores in the group 3 and group 4 were significantly greater than control group(P < 0.05).The results indicated that CD4+CD25+Treg cells could improve kidney function following transplantation,and prolong survival time of transplanted kidney.The 1×106 was the best dosaae for application.

Objective To investigate the effects of different doses of gabapentin on streptozotocin (STZ)-induced diabetic neuropathic pain in rats.Methods Male SD rats aged 6 weeks weighing 180-200 g were used in this study. Diabetes ntellitus ( DM) was induced by intraperitoneal STZ 60 mg/kg and confirmed one week later by blood glucose =16.7 mmol/L before breakfast. The DM rats were randomly divided into 4 groups ( n = 6 each) : gabapentin groups received intraperitoneal gabapentin 30, 60 and 120 mg/kg twice a day (at 9:00 am and 3:00 pm) for 3 weeks respectively and control group received intraperitoneal normal saline 0.6 ml instead of gabapentin. The paw withdrawal threshold to von Frey filament stimulation was measured before and at 30, 60, 120, 180, 240 min after first gabapentin injection and once a week for 3 weeks. Results After gabapentin 60 and 120 mg/kg, the paw withdrawal threshold to mechanical stimuli was significantly increased and lasted for about 4 h. The analgesic effect peaked at 60 min after IP gabapentin injection. Normal saline and gabapentin 30 mg/kg had no significant analgesic effect. The degree of analgesia was significantly decreased at day 14 and 21 of treatment with gabapentin 60 and 120 mg/kg as compared with that at 60 min after gabapentin injection. Conclusion The hyperalgesia and allodynia in rats with diabetes mellitus can be effectively reversed by gabapentin 60 and 120 mg/kg,while long-term use of gabapentin can induce drug tolerance.

In the present study, the apoptotic mechanism and polyamine transporter recognition of WJH-6, a novel polyamine conjugate, were investigated in K562 and HL-60 cells. The cytotoxicity of WJH-6 was assessed by MTT assay; cell cycle distribution and apoptosis were measured by flow cytometry; the protein expression of Caspase-3, Caspase-8, Caspase-9, Bid and mitochondrial membrane potential (MMP) were evaluated by high content screening (HCS) analysis; the protein expression of cytochrome c was measured by Western blotting. The results showed that WJH-6 could be recognized and transported by polyamine transporter (PAT). Furthermore, WJH-6 was able to inhibit K562 and HL-60 cells proliferation and induce apoptosis. This apoptotic effect was relative to MMP loss, cytochrome c release from mitochondria to cytoplasm and the activation of Caspase-8, Caspase-9, Caspase-3 and Bid. These results suggested that WJH-6-induced K562 and HL-60 cells apoptosis was related with mitochondrial damage.

The objective of this study is to examine the effects of ANISpm, a novel polyamine naphthalimide conjugate, with acetylsalicylic acid against hepatocellular carcinoma in vivo and in vitro and elucidate its potential molecular mechanism. The proliferation inhibition was detected by MTT assay. Cell apoptosis, intracellular fluorescence intensity and mitochondrial membrane potential (MMP) were detected by high content screening (HCS) analysis. Polyamines content was analyzed by reverse-phase high performance liquid chromatography Protein expression levels were quantified by Western blotting assay. The combination treatment strongly inhibited cell proliferation, induced cell apoptosis in HepG2 cells and H22 hepatoma cells, which was mediated by enhanced ANISpm uptake via up-regulation of spermidine/spermine N1-acetyltransferase (SSAT) and depression of intracellular polyamine. Furthermore, this synergistic apoptosis was involved in mitochondria and death-receptor signal pathway. All these findings demonstrated that the combination treatment with acetylsalicylic acid and ANISpm resulted in synergistic antitumor effects on hepatoma cells. Thus, combination therapy with these agents may be useful as a potential template for the development of better chemotherapeutic strategy against hepatoma.

BACKGROUND:At present, biological agent-involved immunologic induction therapy gradual y became a key component in immunosuppression therapy of kidney transplantation. It can effectively prevent acute rejection and avoid the appearance of complications. OBJECTIVE:To evaluate the effect of different biological agents on immune state and functional status of transplanted kidney in immunologic induction therapy. METHODS:Clinical data of 110 recipients with kidney transplantation were retrospectively analyzed. In accordance with the conditions of immunologic induction therapy, recipients in the monoclonal antibody group (n=35) received basiliximab. Recipients in the polyclonal antibody group (n=43) underwent rabbit anti-human antithymocyteglobulin. Recipients in the control group (n=32) did not receive immunologic induction therapy. Absolute value of lymphocytes and the number of CD4+T lymphocyte subsets in peripheral blood were comparatively analyzed among three groups at 1, 4 and 12 weeks after kidney transplantation. Functional status of the transplanted kidney and complications of infection were evaluated at 12 weeks after transplantation.RESULTS AND CONCLUSION:The incidence of acute rejection was lower in the monoclonal antibody group and polyclonal antibody group than in the control group (P<0.05). The incidence of infectious complications was higher in the polyclonal antibody group than in the monoclonal antibody group and control group (P<0.05). The absolute value of lymphocytes was lower in the monoclonal antibody group and polyclonal antibody group at 1, 4 and 12 weeks after transplantation than in the control group (P<0.05). The number of CD4+T lymphocyte subsets in peripheral blood was lower in the polyclonal antibody group than in the monoclonal antibody group and control group at 1, 4 and 12 weeks after transplantation (P<0.05). These results suggested that biological agents participate in immunologic induction therapy of kidney transplantation, can effectively suppress the functional status of activated T lymphocytes, and decrease the occurrence of early acute rejection of the transplanted kidney. However, the incidence of infectious complications was higher after the use of rabbit anti-human antithymocyteglobulin.
