Objective To survey the incidence of acquired adult aplastic anemia (AA) in Shanghai, China. Meanwhile, we compared it with the previous data from China in 1986 and other countries in order to explore the trends. Methods Newly diagnosed AA patients were registered in 6 districts (Jingan, Xuhui, Huangpu, Changning, Putuo, Yangpu ) in Shanghai from 2004 to 2006. Then we calculated the crude and age-adjusted incidence of AA according to the population data from Shanghai Statistic Yearbook. Results There were 38 adult patients with acquired AA. The average crude incidence of AA was 0. 33/100 000 from 2004 to 2006. The incidences per 100 000 persons per year were 0. 40, 0. 14and 0. 64 in 18-34, 35-59 and ≥ 60 years, respectively. The rate of severe AA was 0. 17/100 000.Conclusion The incidence of severe AA has no marked change, but the total rate is a little decreased compared with the data from China in 1986.

Objective To observe the clinical efficacy ofFufang Shenlu Granule for kidney-yang deficiency aplastic anemia (AA) and its effects on CD4+ T lymphocyte subsets, and explore its mechanism.Methods Forty AA patients were randomly divided into treatment group and control group, 20 cases in each group. The treatment group was treated withFufang Shenlu Granule combined with conventional western medicine therapy, while the control group was only treated with conventional western medicine therapy. The treatment lasted for 6 months, and follow-up visits lasted for at least one year. The clinical efficacy and T lymphocyte subsets ratio changes before and after treatment in the two groups were observed.Results The clinical efficacy of treatment group was better than that of control group (P<0.05). After treatment, the blood cell counts of the two groups were improved than those of before treatment (P<0.05,P<0.01). After treatment, the red blood cell count and hemoglobin of treatment group were higher than those of control group (P<0.05). Compared with the data before treatment in treatment group, the ratio of CD4+CD25+ cells in all CD4+ cells, and the ratio of CD4+CD25+FoxP3+ cells in all CD4+CD25+ cells increased (P<0.05); the ratio of Th1 and Th2 cells in all CD3+CD4+ decreased (P<0.05). The ratio of Th2 cells was lower than that before treatment in the control group (P<0.05).ConclusionFufang Shenlu Granule can enhance the treatment efficiency of AA with kidney-yang deficiency syndrome. The mechanism may be related to the decrease of Th1 cells, the increase of CD4+CD25+Tregs and their FoxP3 expression.

BACKGROUND: According to present theories and our clinical experience, immune ablative and tolerance inducing theory is proposed. Immune ablative means to clear out mutate cell clones and without transfusion of hemopoietic stem cells afterwards; intolerance inducing means to induce animal models not to react to mutate somatic cells, which avoids relapse or new occurrence of autoimmune disease. OBJECTIVE: To explore the effects of immune-ablative and tolerance inducing therapy in treating animal model of immune polymyositis (PM). DESIGN, TIME AND SETTING: Randomized, controlled animal experiment was performed at the Animal Experimental Center of Nanfang Hospital from December 2008 to April 2009. MATERIALS: One New Zealand rabbit, female, weighing 4.1 kg and 36 England guinea pigs, female, weighing 400-500 g, were used. METHODS: New Zealand rabbit's muscle tissue homogenate and complete Freund's adjuvant (CFA) were injected into guinea pigs to make PM animal models. The 28 animal models were randomly divided into intense immune-ablative and tolerance inducing group (Busulfan 1 mg/kg, every 12 hours, totally 8 doses; followed by CTX 40 mg/kg per day for 4 days; then cyclosporine A (CsA) 3 mg/kg per day was given till animals were dead); cyclophosphamide (CTX) group: CTX was given, 10 mg/kg per day for 3days; immune-ablative and tolerance inducing group: Busulfan 0.8 mg/kg, CTX 30 mg/kg, CsA 3 mg/kg; the administration time and dose were the same as group 1. Control group was not treated.MAIN OUTCOME MEASURES: Full blood count (FBC) and biochemical index were tested before and after treatment, and surviving time was recorded. In addition, muscle pathological changes were observed.RESULTS: Compared with control group, number of white cells was significantly decreased in the other groups, and hematopoiesis function gradually restored after administration. The number of white cells in the immune-ablative and tolerance inducing group was the most, and striated muscle pathology showed PM. Following administration, the glutamic oxaloacetic transaminase and creatine kinase of intense immune-ablative and tolerance inducing and immune-ablative and tolerance inducing groups were significantly reduced (P < 0.05, P < 0.01), but no obvious striated muscle pathological changes were found. The glutamic oxaloacetic transaminase, lactic dehydrogenase and creatine kinase in the CTX and control groups remained unchanged. Survival time of intense immune-ablative and tolerance inducing group was the shortest among all groups, and there was no significant difference between CTX and control groups. The animals in immune-ablative and tolerance inducing group survived for the longest time. CONCLUSION: Immune-ablative and tolerance inducing therapy has preferable effect on treating animal models of PM, and its prognosis is better than intense immune-ablative and tolerance inducing therapy and regular CTX therapy.

Chinese Journal of Modern Nursing 2018;24(4):398-402
Objective To evaluate the effects of dual heart care mode in perioperative period of coronary artery bypass grafting (CABG) surgery on improving health behavior in patients with coronary atherosclerotic heart disease. Methods A total of 131 patients with atherosclerotic heart disease who were treated in the Cardiac Surgery Department of Yancheng Third People's Hospital of Jiangsu Province from January 2011 to December 2016 were recruited by convenience sampling method. All the patients were divided into observation group (2014.1-2016.12, n=68) and control group (2011.1-2013.12, n=63) according to the admission date. The observation group was treated with dual heart path nursing mode, while the control group was treated with routine perioperative care. The scores of self-rating anxiety scale (SAS), health promoting lifestyle profile (HPLP) and the incidence of adverse cardiovascular events were compared between the two groups. Results There was no significant difference in the incidence of anxiety, the scores of SAS and HPLP between the two group on admission (P>0.05). Before surgery and 7 days after surgery, the incidence of anxiety and the score of SAS of the observation group were all lower than those of the control group, and the difference was statistically significant (P<0.05). The score of HPLP of the observation group was higher than that of the control group before discharge, and the difference was statistically significant (P<0.05). After surgery, there were 6 cases of adverse cardiovascular events in the observation group, and 17 cases in the control group. The incidence of adverse cardiovascular events in the observation group was significantly lower than that in the control group, with statistical significant difference (P< 0.05). Conclusions Dual heart path nursing mode guides nurses to give standardized perioperative holistic nursing and psychological nursing according to predetermined care plan, so that the perioperative nursing work is more standardized, more secure and more humanized. In conclusion, it improves the quality of nursing overall.

OBJECTIVETo investigate the effect of human cytomegalovirus (HCMV) infection on T lymphocyte subsets in children with β-thalassemia major (TM) during the initial 6 months after allogeneic hematopoietic stem cell transplantation (Allo-HSCT).
METHODSFrom January, 2010 to January, 2011, 35 children with TM underwent Allo-HSCT. Peripheral blood samples were obtained from the children 6 month after the transplantation to examine the changes of T lymphocytes subsets in relation to HCMV seropositivity.
RESULTSThirteen children were found seropositive and 22 were seronegative for HCMV. The HCMV-seropositive children had a higher CD8⁺ cell percentage but a lower CD4⁺ cell percentage than those without HCMV infection. Compared with those seronegative for HCMV, the children with HCMV seropositivity showed increased percentages of CD8⁺ cells and CD8⁺CD28⁻ cells with a decreased percentage of CD8⁺CD28⁺ cells. A positive linear correlation was found between the percentages of CD8⁺CD28⁻ cells and CD8⁺ cells.
CONCLUSIONHCMV infection can lead to the accumulation of CD8⁺CD28 cells to cause increased CD8⁺ T cells in the peripheral blood in TM children after Allo-HSCT. The percentages of CD8⁺CD28⁻ cells has a positive linear correlation to that of CD8⁺ cells.

OBJECTIVETo investigate the effects of different doses of antithymocyte globubin-fresenius (ATG-F) for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with beta-thalassemia Major.
METHODSSixty-four children with beta-thalassemia major undergoing allo-HSCT were divided into two equal groups to receive ATG-F pretreatments at high (30 mg/kg) or low (15 mg/kg) doses as part of the conditioning regimen including mainly cyclophosphamide, busulfan, fludarabine, and thiotepa. The outcomes of the patients were compared between the two groups.
RESULTSNo obvious difference were noted in the time to leukocyte and platelet engraftment between the two groups. The incidence of grade II-IV acute graft-versus-host disease (aGVHD) appeared to be higher in the low-dose group than in the high-dose group (12.5% vs 9.4%). The incidence of grade III-IV aGVHD was also higher in the low dose group (12.5% vs 6.3%), but the difference was not statistically significant. Application of high-dose ATG-F was associated with a higher rate of probable and possible fungal infection (P<0.05).
CONCLUSIONThe two doses of ATG-F is feasible as a part of the conditioning regimen for allo-HSCT in children with beta-thalassemia major.

The maintenance of the balance between oxygen supply and oxygen consumption is a key measure in preventing acute kidney hypoxic/reoxygenation injury. Morphine can inhibit metabolism and reduce the oxygen consumption. We tried to investigate the protective effects of morphine hypoxic preconditioning on acute kidney hypoxic/reoxygenation injury in rabbit and its influence on expression of caspase-3 protein. Kidney hypoxic and reoxygenation were induced by making the tested rabbits inhale 8% oxygen for three hours firstly, and then putting them in the air to breathe in normal oxygen for another three hours. Morphine hypoxic preconditioning was induced by administering morphine 3 mg/kg, and then hypoxic of 8% oxygen was induced. Caspase-3 protein expression in renal tissue was assessed by immunohistochemical method. In the present study, the expressions of caspase-3 protein were significantly higher in saline-control hypoxic group than in morphine hypoxic preconditioning group ((29.3+/-5.7)% vs. (12.16+1.23)%, P<0.05). These observations suggested that morphine hypoxic preconditioning can protect rabbit against acute kidney hypoxic/reoxygenation injury by decreasing expression of caspase-3 protein.

OBJECTIVETo assess the value of magnetic resonance imaging T2* tests in the detection of myocardial and liver iron overload in patients with β-thalassemia major (β-TM).
METHODSFrom 2010 to 2011, 28 β-TM patients over 10 years old under blood transfusion therapy and chelation care with serum ferritin (SF)>1000 µg/L underwent myocardial and liver MRI T2* tests on a voluntary basis. The results were analyzed in relation with age, SF, and left ventricular ejection fraction (LVEF).
RESULTSFourteen out of the 28 cases (50%) were found to have myocardial iron overload, including 7 severe cases, 2 moderate cases, and 5 mild cases. All the 28 cases had liver iron overload, including 2 mild cases, 7 moderate cases, and 19 severe cases. Two out of the 28 cases had lowered LVEF (7.14%), and one of them had severe myocardial iron overload. There was a negative correlation between myocardial MRI T2* and SF (r=-0.479, P=0.01). Myocardial MRI T2* was positively correlated with liver MRI T2* (r=0.378, P=0.047). Age was not significantly correlated with SF, LVEF, or liver MRI T2*.
CONCLUSIONMagnetic resonance imaging (T2*) detection is an effective and non-invasive means for detecting myocardial and liver iron overload in patients with β-thalassemia major receiving blood transfusion. T2* combined with SF is the main diagnostic indicator to assess iron overload in the vital organs.
