Objective To investigate the clinical features and prognosis of adult dermatomyositis with gastrointestinal bleeding and perforation. Methods The clinical data of a adult dermatomyositis with gastrointestinal bleeding and perforation were retrospectively analyzed. And the clinical characteristics of this patient were analyzed, combined with 7 cases reported in the literature. Results Among the 8 cases, 6 cases were females and 2 cases were males, aged 18 to 63 years. The 5 cases had melena, 3 cases had hematemesis, 3 cases had hematochezia and 1 case had hemoptysis. The main treatment was glucocorticoids, immunosuppressive agent, intravenous immune globulin (IVIG), endoscopic hemostasis and angiographic embolization. Four of the 8 cases died. Conclusions Adult dermatomyositis with gastrointestinal bleeding and perforation is rare, but the condition is dangerous and the mortality is high. Dermatomyositis with early onset of abdominal pain, vomiting, melena should be alert to serious complications such as gastrointestinal bleeding and perforation.

AIM:To explore the role of α7 nicotinic acetylcholine receptor (α7nAChR) in anti-inflammation of glucocorticoids (GCs) at physiological concentrations .METHODS: MTT assay was used to measure the viability of BV-2 cells, which were processed by hydrocortisone at different concentrations .On the basis of inflammatory model induced by LPS in BV-2 cells, experimental groups were divided as follows:(1) control;(2) LPS;(3) GCs+LPS;(4) methyl-lycaconitine ( MLA)+GCs+LPS.The levels of TNF-αand IL-1βin the cell supernatants were detected by ELISA .RE-SULTS:Hydrocortisone at concentrations of 2 000 and 1 000 nmol/L decreased the cell viability to (76.9 ±5.5)% and (90.8 ±7.3)%, respectively, indicating the cellular injury by GCs at over-physiological doses.LPS significantly induced the releases of TNF-αand IL-1βin a time-and dose-dependent manner in BV-2 cells.Hydrocortisone at physiological con-centrations (500 and 250 nmol/L) reduced the releases of TNF-αand IL-1βin BV-2 cells stimulated by LPS, and MLA at concentration of 10 nmol/L antagonized the anti-inflammatory effect of GCs .CONCLUSION:α7nAChR is involved in the anti-inflammatory effect of the physiological concentrations of GCs .

The outcome of the elderly patients with acute myeloid leukemia (AML) has not improved in the last three decades. Their clinical features limit the ability to tolerate intensive cytotoxic chemotherapy and result in greater early mortality. The AML seen in elderly patients is also more likely to have greater resistance to therapy. Attempts to improve outcome have generally been unsuccessful But further manipulation of standard cytotoxic chemotherapy alone is unlikely to improve the outcome for the majority of patients with AML.

Objective To study the phosphorylation mode of extracellular regulated kinase( ERK)induced by acute and chronic morphine treatment on Chinese hamster ovary( CHO)cells expressed withμopioid receptors. Methods The time course of ERK phosphorylation 1 h and 36 h after morphine exposure as well as naloxone-precipitated withdrawal was detected by immunobloting. Results A transient enhancement of ERK phosphorylation was induced by 1 μmol · L-1 morphine with the peak effect at 5 min(P〈0. 01),and the effect was dose-dependent. No difference in ERK phosphorylation was found after 36h of treatment with 10 μmol · L-1 morphine compared with the control. However,5 or 10 min-naloxone precipitation induced remarkable decrease in ERK phosphorylation compared with the control(P〈0. 01). Conclusion Different changes of ERK phosphorylation were found under acute and chronic morphine treatment and naloxone precipitation,indicating a compensation of ERK related pathway induced byμ opioid receptors.

Recent studies have shown that immune cells play an important role in the development of non-immune diseases.Regulatory T cells (Treg) are a group of T cell subsets which have immunoregulatory and immunosuppressive functions.Abnormalities in the number and function of Treg cells may cause immune imbalance, which leads to the development of diseases.Immunometabolic disorders may in turn affect the generation, proliferation and function of Treg cells.Clarification of the relationship and interaction between immunometabolism and Treg cells will make it possible to treat metabolic diseases with cellular immunotherapy.

Objective To determine the therapeutic efficacy of curcumine on inflammatory bowel disease(IBD)and its underlying mechanisms.Methods The rat ulcerative colitis model was developed by using 30 g/L dextran sulfate sodium.Twenty-four young rats were divided into 4 groups:normal group,model group,curcumin 100 mg/kg group(curcumin 100 group),and curcumin 300 mg/kg group(curcumin 300 group).Curcumin was given through gastric gavage once a day for 7 days.General condition,disease activity index(DAI)and histopathological score(HPS)were evaluated.The proportions of CD4+ CD25+ Foxp3+ regulatory T cells(Treg)and CD4+ IL-17+ helper T lymphocyte 17(Th17)in CD4+ T cells in rats,and spleen cells were calculated by using flow cytometry.Immunohistochemical method was performed to determine the level of SOCS3 in colon tissues.Results After curcumin administered through gastric gavage for 5 days,compared with the DAI in the model group[(7.50±0.32)scores],HPS in the curcumin 100 group[(4.00±1.10)scores] and the curcumin 300 group [(5.00±0.89)scores] significantly reduced,and the difference was significant(F=12.469,P<0.05).After curcumin administered through gastric gavage for 7 days,compared with the HPS in the model group[(2.69±0.70)scores],histological score in the curcumin 100 group[(1.94±0.68)scores],the curcumin 300 group [(2.00±0.63)scores] and the normal group[(0.50±0.05)scores] significantly reduced,and the difference was significant(F=33.282,P<0.05).Compared with the model group[(0.015 1±0.000 7)D],the expression of SOCS3 in the curcumin 100 group[(0.002 0±0.000 5)D],the curcumin 300 group [(0.002 6±0.006 0)D] and the normal group[(0.002 2±0.001 0)D] was significantly inhibited(F=382.270,P<0.05),but there was no difference among the former 3 groups(F=0.828,P>0.05).Compared with the model group[(6.5±1.5)％],the propotion of CD4+ CD25+ Foxp3+ Treg cells in CD4+ T cells in the curcumin 100 group[(9.9±1.0)％],the curcumin 300 group [(9.3±0.7)％] and the normal group[(9.6±1.1)％]was obviously upregulated(F=16.635,P<0.05),but there was no difference among the former 3 group(F=1.564,P>0.05).Compared with the model group[(3.5±1.4)％],the propotion of CD4+ IL-17+ Th17 cells in CD4+ T cells in the curcumin 100 group[(2.0±0.9)％],the curcumin 300 group [(1.2±0.6)％] and the normal group[(2.0±0.9)％] was downregulated(F=5.155,P<0.05),but there was no difference among the former 3 group(F=2.073,P>0.05).There was no obvious difference between the curcumin 100 group and the curcumin 300 group in these indicators respectively(all P>0.05).Conclusions Curcumin probably attenuates IBD severity,reduces inflammation and regulates the balance of Treg/Th17 through the inhibition of SOCS3 expression.

AIM: To investigate the synergistic effect of resveratrol and 5-fluorouracil on osteosarcoma CD133+ cell subset.METHODS: Human osteosarcoma cell line MG-63 CD133+ cell subset and the corresponding CD133-cell subset were treated with resveratrol and 5-fluorouracil.After treatment, the viability of MG-63 cells was measured by MTT assay.The apoptosis of MG-63 cells was analyzed by flow cytometry.Activation of caspase-9 and caspase-3, the expression of Apaf-1, and the release of cytochrome C were evaluated by Western blot.The interaction between Apaf-1 and pro-caspase-9 was detected by co-immunoprecipitation.RESULTS: The cell death and apoptosis of MG-63 CD133+ cell subset induced by 5-fluorouracil were significantly weaker than those in the corresponding MG-63 CD133-cell subset.However, co-treatment with resveratrol significantly enhanced the effect of 5-fluorouracil on inhibiting the viability of MG-63 CD133+ cell subset.Mechanically, treatment with resveratrol upregulated the expression of Apaf-1.Transfection with Apaf-1 siRNA abolished the synergistic effect of resveratrol and 5-fluorouracil in MG-63 CD133+ cell subset.In addition, the results of co-immunoprecipitation indicated that the combination of resveratrol and 5-fluorouracil significantly induced the formation of Apaf-1/pro-caspase-9 complex, leading to the activation of caspase-9 in MG-63 CD133+ cell subset.CONCLUSION: Resveratrol enhances 5-fluorouracil-induced apoptosis of osteosarcoma CD133+ cell subset by promoting the formation of Apaf-1/caspase-9 complex.

Objective: To investigate the efficacy of progesterone tablets in the patients with unexplained recurrent spontaneous abortion and the influence on cellular immunity factor.Methods: Totally 90 cases of unexplained recurrent spontaneous abortion patients were randomly divided into the observation group and the control group (45 ones in each).After pregnancy, the control group was given intramuscular injection of human chorionic gonadotropin, and the observation group started to be treated with progesterone tablets on the 35th day after menolipsis.The levels of interleukin-4 (IL-4), interleukin-10 (IL-10), interleukin-17 (IL-17) and IFN-γ were determined, and the expression of T helper lymphocytes (Th17/CD4+), regulatory T lymphocytes (Treg/CD4+) and T helper lymphocytes regulatory T lymphocytes (Th17/Treg) was compared before and after the treatment.The pregnancy success rate and abortion rate were compared between the groups after the treatment, and adverse reactions were also observed.Results: After the treatment, the expression levels of IL-4 and IL-10 in the observation group were higher than those in the control group, and the expression levels of IL-17 in the observation group was lower than that in the control group, and the differences between the groups were significant (P＜0.05);after the treatment, the expression of Th17/CD4+ and Th17/Treg in the two groups decreased, and that in the observation group was lower than that in the control group;after the treatment, the expression of Treg/CD4+ in the two groups increased, and that in the observation group was higher than that in the control group, and the difference was significant (P＜0.05);after the treatment, the expression of IFN-γ in the two groups decreased, and that in the observation group was lower than that in the control group;after the treatment, the pregnancy rate in the observation group was higher than that in the control group with lower abortion rate, and the differences were statistically significant (P＜0.05).The incidence of adverse reactions in the observation group was lower than that in the control group(P＜0.05).Conclusion: Progesterone tablets in the treatment of unexplained recurrent abortion patients show significant effects, and can effectively improve the cellular immune factor in the patients, which is worth promoted application in clinics.
