Objective To study the effect of early rehabilitation with full range of music therapy on acute coronary syndrome (ACS) patients after emergency PCI. Methods From July to December 2009, 108 inpatients undergone emergency PCI were randomly divided into experimental group and control group, with 54 patients in each group. The experimental group received full range of music therapy, which included PCI treatment under the circumstance of music and music therapy 3 times per day (10:00 a. m. , 16:00 p. m. and 21:00 p. m. ) during hospitalization. The control group received conventional treatment. SBP, HR, the left ventricular ejection fraction (LVEF) , 6-MWT, length of stay, the scale of anxiety and depression were compared between the two groups. Results The scores of anxiety and depression, SBP, HR, LVEF and 6-MWT in the experimental group were significantly different from those of the control group ( P < 0. 05). Conclusions Full range of music therapy significantly contributes to the rehabilitation of ACS patients after emergency PCI.

The purpose of this research is to investigate the critical period of voltage-gated Na(+) channel development in hippocampal CA1 neurons. Changes of Na(+) currents in acutely isolated hippocampal CA1 neurons of rats at different ages (0-4 weeks after birth) were recorded using the whole-cell patch-clamp technique. The results indicated that the maximum current density of Na(+) channels was increasing with age, and the amplitudes in 1, 2, 3 and 4 weeks respectively grew by (42.76 ± 4.91)%, (146.80 ± 7.63)%, (208.79 ± 5.28)% and (253.72 ± 5.74)% (n = 10, P < 0.05) compared with that in 0 week. The current density in CA1 neurons of 1-2 weeks after birth increased more significantly than those of other groups. The activation curve of Na(+) channel shifted to the left. The half-activation voltages (mV) in 0-2 weeks were -39.06 ± 0.65, -43.41 ± 0.52, -48.29 ± 0.45 (n = 10, P < 0.05), respectively, showing significant age-dependent decrease, and there were no significant changes in other groups. The slope factors of activation curve for each group did not change significantly. There were no regular changes in inactivation curve and no significant changes in half-inactivation voltage. The slope factors of inactivation curve in 1-2 weeks were: 5.77 ± 0.56, 4.42 ± 0.43 (n = 10, P < 0.05). The inactivation rate of the second week after birth was faster than that of the first week, and there were no significant changes during 0-1 week and 2-4 weeks. The recovery from inactivation curve of Na(+) channel shifted to the left. The recovery time declined in 1-3 weeks. Changes of action potential properties were consistent with Na(+) current. These results suggest that the period of 1-2 weeks after birth may be the critical development period of voltage-gated Na(+) channel in hippocampal CA1 neurons. During this time, the distribution of Na(+) channel increases significantly; the activation curve of Na(+) channel shifts to the left; inactivation rate increases as well as recovery time shortens.

OBJECTIVETo describe epidemiological characteristics of an outbreak of severe acute respiratory syndrome (SRAS) in Dongcheng District, Beijing during March to June 2003.

METHODSData of SARS cases notified from Dongcheng District Center for Disease Control and Prevention (CDC) and supplemented by other channels were collected. All data were input into dataset files by Microsoft Excel-2000 software and analyzed with SPSS version 10.0 software.

RESULTSTotally, 572 cases notified were collected during this period in Dongcheng District, Beijing, and 99 of them were excluded from SARS, because of diagnosis of common cold, pneumonia, measles, or rubella, etc. Actually, 473 SARS cases were analyzed. Attack rate of SARS in permanent residents of Dongcheng was 28.3 per 100,000. Forty-one of them died, with a case-fatality ratio of 8.7%. Outbreak of SARS in Dongcheng District started on March 14, with a peak during mid- and late April, and dropped from May 5, 2003. Persons were all susceptible to SARS, with the highest proportion at ages of 20-50 years, which accounted for 68.7% of the total cases. Average age of the patients at their onset was 40.7 years. No gender difference in SARS cases was found. Number of SARS cases in health care workers (HCWs) accounted for 18.0% and that in the retired persons accounted for 15.4% of the total cases. Cases occurred in all 10 sub-districts of Dongcheng. Totally, 230 of the 572 notified cases (40.2%) hospitalized at local hospitals under the jurisdiction of Dongcheng District. Eighteen of 85 cases of SARS occurred in health care workers of local hospitals, accounting for 4.5% of the total number of health care workers working at the wards caring for SARS patients or at fever clinics. There were 34.7% of SARS cases without any contact histories before their onset. Familial aggregation phenomena were observed in 41.8% of the cases and 18.1% of households. And, 7.4% (attack rate) in those exposed to SARS cases suffered the illness during the periods of quarantine.

CONCLUSIONSSARS appeared outbreak in Dongcheng District, Beijing during March to June 2003. People were all susceptible to SARS, which mainly threatened the young adults and the middle-aged, as well as health care workers and the retired workers. Main mode of transmission was exposure to SARS patients in a near distance at hospitals or families. Prevention and control of SARS should be focused on early isolation of patients and quarantine for the contacts. Current available measures to prevent and control SARS proved effective.

Objective To investigate the relationship between appendicular skeletal muscle composition(muscle mass and muscle index)and glycosylated hemoglobin A1c(HbA1c)level in type 2 diabetes mellitus(T2DM)patients.Methods A total of 459 adult T2DM patients hospitalized in the Department of Endocrinology,Tangdu Hospital of Air Force Medical University from April 2021 to June 2022 were selected as the research objects.Bioelectrical impedance analysis was used to evaluate the body composition of the patients.The patients were divided into two groups according to HbA1c level:standard glycation group(HbA1c≤7.0%,n=145)and unqualified glycation group(HbA1c>7.0%,n=314).The two groups'general data,biochemical indexes,muscle content,fat content and other body composition were analyzed.Spearman correlation analysis and multiple logistic regression analysis were used to analyze the relationship between body composition and glycemic control in type 2 diabetic patients.Results The appendicular skeletal muscle mass and its index(ASMI)of the patients in the standard glycation group were better than those in the unqualified glycation group(P<0.05).However,there were no significant differences in gender,history of antidiabetic drugs and body fat(body fat content,limb fat content and visceral fat content)between the two groups(P>0.05).Spearman correlation analysis showed that appendicular skeletal muscle mass and its index were negatively correlated with HbA1c(r=-0.158,P=0.001;r=-0.187,P<0.001).Logistic regression analysis showed that upper limb skeletal muscle mass(OR=3.570,95%CI 2.293-5.559)and lower limb skeletal muscle mass(OR=1.297,95%CI 1.146-1.468)were independent protective factors for achieving glycation standard in HbA1c group.Conclusions The skeletal muscle mass of limbs is a protective factor for reaching the standard of HbA1c.With the increase of skeletal muscle mass of limbs,the level of HbA1c gradually decreases.Among them,the increase of upper limb muscle mass has a stronger correlation with reaching the standard of HbA1c.

Objective To study the effect of improvement music therapy on ACS patients after PCI.Methods From July to December 2009,108 patients who were hospitalized after emergency PCI were divided into the experimental group (EG) and the control group (CG) randomly, with 54 patients in each group. The EG received improvement music therapy for 3 times per day, 10 ～ 15 min for once in-patient; and continue improvement music therapy out-patient for 2 times per day, 15 ～ 30 min for once. The LVEF, the scale of anxiety and depression and SF-36, SAQ et al were compared between the two groups using t and X2 test.Results The scale of anxiety and depression, the LVEF and SF-36,SAQ in the EG was statistically significant different from those of the CG ( P ＜ 0.01 ). Conclusions Improvement music therapy could significantly influence the patients' rehabilitation effect after PCI.

OBJECTIVETo evaluate the efficacy and safety of antifungal prophylaxis of itraconazole in patients with acute myeloid leukemia (AML) to probe the relationship of the antifungal effect and the adverse events with serum concentration.

METHODSFrom April 2009 to May 2011, a total of 310 courses from 112 patients referred to our institute were enrolled in this study; of them, 297 courses were eligible for analysis. Eligible cases were randomized into oral group and injection/oral group according to different chemotherapy of induction and consolidation. Blood samples were collected at different time points for measurements of serum itraconazole levels. The morbidity of IFI and the adverse events were analyzed.

RESULTSThe morbidities of IFI in injection/oral and oral groups were 10.1% and 20.9%, respectively (P=0.010). 7 and 9 cases in injection/oral and oral groups, respectively were withdrawn from the study because of adverse events, and the difference between these two groups was of no significance. Serum itraconazole levels of injection/oral and oral groups were 672(299-1097) μg/L and 534(210-936) μg/L, respectively (P<0.01).

CONCLUSIONAntifungal prophylaxis with itraconazole in AML patients was effective and safe. Prophylactic effect with injection/oral itraconazole was superior to oral itraconazole solution; moreover, prophylactic effect of itraconazole was highly correlated with its serum level.

OBJECTIVETo study the clinicopathologic features of myeloid sarcoma and to evaluate the role of immunohistochemical study in diagnosis of this entity.

METHODSEighty-two cases of myeloid sarcoma were retrieved from the archives of Department of Pathology, West China Hospital of Sichuan University during the period from January, 1990 to February, 2005. The morphologic features were reviewed and classified according to the 2001 WHO classification for hematopoietic and lymphoid tissue tumors. Immunohistochemical study using a panel of 11 antibodies was performed on 73 cases. The survival data were collected and analyzed by SPSS 10.0.

RESULTSThe median age of patients was 35.5 years. The male-to-female ratio was 1.4:1. The sites of occurrence included lymph node (43.1%), skin (16.7%), nose (7.8%), soft tissue (7.8%) and bone (6.9%). Fifty-one cases (62.2%) represented myeloid sarcoma associated with an underlying myeloproliferative disorder and 25 cases (30.5%) represented solitary myeloid sarcoma. As for the morphology, 79 cases (96.3%) were granulocytic sarcoma, including 41 cases (51.9%) blastic type, 25 cases (31.6%) immature type and 13 cases (16.5%) differentiated type. The other 3 cases (3.7%) were monoblastic sarcoma. Immature eosinophils were found in 51 cases (64.6%) of granulocytic sarcoma, among which 13 cases (31.7%) were of blastic type. Immunohistochemical study showed that 95.9% cases (70/73) were positive for myeloperoxidase, 95.5% (63/66) for lysozyme, 95.2% (60/63) for CD68 (KP1), 90.8% (59/65) for leukocyte common antigen, 85.7% (54/63) for CD43, 77.8% (49/63) for CD117, 58.7% (37/63) for CD99, 54.0% (34/63) for CD15, 22.2% (14/63) for CD34, and 4.7% (3/64) for CD68 (PG-M1). Proliferation index, as demonstrated by Ki-67 positivity, was 0.49+/-0.22. Follow-up data was obtained in 59 of the 82 patients. The two- and five-year survival rates were 36.1% and 17.3% respectively. No significant prognostic factors were found in the survival analysis.

CONCLUSIONSMyeloid sarcoma may precede, develop in a background of myeloproliferative disorder or even after remission of the disease. The presence of immature eosinophils is an important morphologic clue and immunohistochemical study plays an essential role in arriving at a correct diagnosis. Immunopositivity for myeloperoxidase is specific for granulocytic differentiation, while CD68 (PG-M1)-positivity suggests monocytic differentiation. Detailed clinicopathologic correlation is also helpful.

To explore the effects of ABO incompatibility between recipient and donor on HLA-matched nonmyeloablative allogeneic peripheral blood stem cell transplantation (NAST), a retrospective, cohort study was performed. Among 24 HLA-matched NAST, 15 were major ABO-incompatible and 9 minor. Control group included 24 HLA-matched NAST with ABO-compatible grafts. Nonmyeloablative conditioning regimens consisted of CTX, Ara-C and ATG. The patients were given cyclosporine A and mycophenolate mofetile for prophylaxis of acute GVHD. The ABO-incompatible patients received grafts depleted erythrocytes by hydroxyethyl starch (HES) sedimentation. The results showed that successful and stable engraftment was established in 23 patients. No recipient developed clinically immediate hemolysis during graft infusion, but 2 recipients experienced delayed hemolysis attributable to the ABO incompatibility. The median time of granulocyte counts >0.5 x 10(9)/L and platelet >30 x 10(9)/L was 11 and 14.9 days, respectively. In ABO major incompatible group, the onset of erythropoiesis after NAST was delayed. One out of 10 recipients with blood group "O" in this group developed pure red cell aplasia (PRCA), lasting 5 months. The acute GVHD occurred in 7 out of the 24 patients. The chronic GVHD occurred in 5 of 21 cases. Relapse was observed in 2 patients with acute leukemia. The actuarial probability of disease-free survival at 2 years was 63.3%. In conclusion, ABO-incompatible grafts for NAST have no adverse effect on engraftment, recovery of platelets, incidence of GVHD, relapse rate or survival. ABO-incompatible NAST is fairly safe if there is indication, however, the onset of erythropoiesis is delayed when major ABO mismatched.
