Objective To explore the effect of pulmonary rehabilitation on activities of daily living(ADL)and pulmonary function in patients with chronic schizophrenia complicated with pulmonary infection at stable stage. Methods From January,2014 to July,2017,62 patients with chronic schizophrenia complicated with pulmonary infec-tion at stable stage were randomly divided into control group(n=31)and observation group(n=31).Both groups accepted routine medication,while the observation group received pulmonary rehabilitation for two months in ad-dition.The distance of 6-Minute Walk Test(6MWT),the modified Barthel index(MBI),modified British Medi-cal Research Council Dyspnea Scale (mMRC), C-reactive protein (CRP), Zung Anxiety Self-Rating Scale and Zung Depression Self-Rating Scale were compared before and after training. Results The total effective rate was higher in the observation group than in the control group(χ2=5.415,P=0.020).Com-pared with the control group,the distance of 6MWT increased(t=5.463,P=0.008),the score of MBI increased(t=2.142, P=0.028), the score of mMRC decreased (t=3.689, P=0.013), and the level of CRP decreased (t=-2.179,P=0.031)in the observation group.The scores of Zung Anxiety Self-Rating Scale(t=5.048,P=0.009) and Zung Depression Self-Rating Scale(t=-1.388,P=0.045)both decreased. Conclusion An early implementation of pulmonary rehabilitation could improve ADL and the exercise endurance,and reduce the incidence of infection in patients with chronic schizophrenia complicated with pulmonary infection at stable stage.

OBJECTIVETo study the therapeutic effects of azithromycin in treatment of congenital toxoplasmosis in children.

METHODSDefinite diagnosis of congenital toxoplasmosis was made on the basis of clinical manifestation combined with one or more positive results of the following laboratory tests and excluded other congenital infectious diseases: toxoplasma DNA (TOX-DNA), circulating toxoplasma antigen (TOX-CAG), and toxoplasma IgM antibody (TOX-IgM). All the patients were given oral azithromycin 10 mg/(kg.d) for 6 days followed by 8 days without medication (one course of treatment), and the regimen was persisted for 2 months and then another 2-month treatment was given at a 1-month interval. The authors continued to provide further treatment according to the state of the illness at one month interval. The patients received 2 to 8 (average 5) courses of treatment. The patients were followed-up for 2.5 to 5 (average 4) years.

RESULTSThe treatment was effective in all the patients and the patient's condition was improved. The authors repeated in 12 cases the four tests for toxoplasma (TOX-DNA, TOX-CAG, TOX-IgM, and TOX-IgG) 9 months to one and a half years after treatment. In 10 cases all these tests showed negative results, in 2 cases TOX-IgG was positive and in the other 4 cases symptoms disappeared.

CONCLUSIONThe results of the study showed that oral azithromycin had significant therapeutic effects with little side effect and was well tolerated. Azithromycin may become an alternative therapy in treatment of congenital Toxoplasma gondii infection in children.

OBJECTIVETo investigate the quantity and function of circulating dendritic cells (DC) in patients with chronic idiopathic thrombocytopenic purpura (ITP).

METHODSHigh dose dexamethasone (HD-DXM) at a dose of 40 mg orally per day for four consecutive days was the initial treatment for chronic ITP patients. Flow cytometry was used to analyze the number of myeloid DC (mDC), plasma cytoid DC (pDC) and CD4+FOXP3+ T cells in patients before and after the treatment, meanwhile the co-stimulatory molecules on circulating DCs were assayed as well. Monocyte-derived DCs and CD4+ T cells were co-cultured with autologous or allogeneic normal fresh platelets and after 6 days of incubation H-TdR was used to assay the proliferation of CD4+ T cells.

RESULTSThe absolute numbers of circulating mDC and pDC were not significantly different between pre-treatment patients and healthy controls (P > 0.05 and P >0.05). However, percentage of CD4+ FOXP3+ T cells was decreased (P < 0.01), and their percentage was inversely correlated with the number of pDC and mDC (r = -0.396, P =0.045 and r = -0.410, P =0.037). The initial response rate to HD-DXM was 92.3%. After 4-days treatment, CD4 FOXP3+ Treg cells increased (P <0.01) while pDCs decreased (P <0.01). Although mDCs increased after HD-DXM (P <0.05), their CD11c expression level was decreased (P < 0.01), the mean fluorescence intensity (MFI) decreased from 340 +/- 30 before treatment to 199 +/- 21 after treatment. The inverse correlation between pDCs and CD4+ FOXP3+ Treg cells remained (r= -0.524, P =0.006) while that between mDCs and Treg cells disappeared (r = - 0.360, P =0.071). The MFI of CD86 on DCs was higher in ITP patients than in healthy controls (P <0.05), while the proportions of CD86, CD40, CD80 and the MFI of CD40, CD80 in ITP patients were normal (P > 0.05). DCs from chronic ITP patients co-cultured with autologous or allogeneic platelets were highly efficient in stimulating autologous CD4+ T cells proliferaton as compared to those derived from healthy donors (P < 0.05 and P <0.05).

CONCLUSIONDCs may play a role in the pathogenesis of chronic ITP in relation with CD4+CD25+ Treg cells.

OBJECTIVETo explore the effect of one dressing of porcine acellular dermal matrix on deep partial thickness burns.

METHODSFrom January 1997 to January 2004, sixty-seven cases of deep partial thickness total burned surface area (TBSA) from 50% to 90% burn wound were treated by a single dressing of porcine acellular dermal matrix (the porcine acellular dermal matrix group). Ten cases of deep partial thickness burned patients with the same TBSA treated by exposure method served as the exposure method group. The healing time of the wound was observed. The patients were followed up for 3 months to 2 years, and the scar proliferation was observed.

RESULTSThe deep partial-thickness wound would be healed without dressing change in the porcine acellular dermal matrix group, and the average healing time was (12.2 +/- 2.6) days. The average healing time of the exposure method group was (27.4 +/- 3.5) days. Follow up of the patients within 3 months to 2 years showed that scar proliferation in the porcine acellular dermal matrix group was much less than that in the exposure method group, even no scar proliferation was observed in some patients.

CONCLUSIONWithout tangential excision, autografting and dressing change, a single dressing of porcine acellular dermal matrix on deep partial thickness burn wound could shorten the healing time and inhibit scar proliferation.

OBJECTIVETo investigate the clinical features of coronary artery spasm patients with or without myocardial bridge and explore the roles of endothelial dysfunction in these patients.

METHODSOne hundred eighteen patients undergone acetylcholine provoking test were divided into myocardial bridge (MB) group (n = 26) and non-myocardial bridge (NMB) group (n = 92). The results of acetylcholine test, treadmill exercise electrocardiography, stress myocardial perfusion scintigraphy, plasma level of endothelin-1 and nitric oxide were compared between MB group and NMB group.

RESULTSCoronary artery spasm was induced in 21 patients in MB group (81%) and 52 patients in NMB group (57%, P < 0.05). Positive treadmill electrocardiography was obtained in 19 patients in MB group (73%) and 7 patients in NMB group (8%, P < 0.001). Ischemic perfusion defect in 20 (77%) and 9 patients (10%, P < 0.001) and reverse redistribution in 23 (88%) and 68 patients (74%, P > 0.05). Patients showed different clinical features in MB group and NMB group (more short-duration exertional angina and could not be readily released by nitroglycerine in MB group while more patients experienced long-lasting variant angina and symptoms could be readily released by nitroglycerine). Plasma endothelin-1 level was significantly higher [(132.1 +/- 6.5) ng/L vs. (108.5 +/- 8.2) ng/L, P < 0.01] while nitric oxide was significant lower [(84.7 +/- 17.5) ng/L vs. (99.8 +/- 18.2) ng/L, P < 0.05] in MB group compared to NMB group.

CONCLUSIONMB patients were prone to coronary artery spasm partly due to endothelial dysfunction. Patients with MB and coronary artery spasm also showed classic clinical symptoms and positive stress tests for ischemia.

OBJECTIVETo investigate the role of xenogenic (porcine) ADM as dermal substitute in scar treatment.

METHODSAfter scar excision, the wounds were covered with composite grafts of DR procine ADM and autologous thin split-thickness grafts in one stage or in two stages.

RESULTS22 out of 47 cases were treated in two-staged procedure. After the ADMs were applied to the wound, the autologous thin split-thickness grafts were implanted 7 days later. 25 cases were treated in one-staged procedure. The survival rates of composite grafts were (88.3 +/- 3.7)% for subcutaneous recipient bed and (89.7 +/- 3.4)% for deep fascia recipient bed in group with two-staged procedure, compared with (92.5 +/- 4.1)% and (93.2 +/- 5.2)%, respectively, in group with one-staged procedure. Early after grafts taken, the grafts had a pink colour and smooth surface. The patients were followed up for 90 days at most. The survived composite grafts were durable, elastic, smooth and soft with good function and appearance like normal skin. They could even be pinched up. The scar along the edge of the grafts was slightly hypertrophic.

CONCLUSIONSThe survival rate of composite graft is higher in patients with one-staged procedure. The elasticity and textural of the taken grafts are better on subcutaneous recipient bed than on deep fascia recipient bed, though the function has no difference. Xenogenic (porcine) ADM can be an optimal dermal substitute for wound coverage after scar excision.

[Abstract] Objective To investigate the appropriate X-ray angle which image can represent total proximal of femur according to the anatomic shape of the femoral neck section. Methods The anatomic parameter of the femoral neck section was observed and measured. Found the femoral neck was contained with three main surfaces of anterior surface, posterosuperior surface and posteroinferior surface. A model of surface fluoroscopy has been made by covering aluminum foil papers on the three surfaces of femoral neck. Taking the midpoint of the femoral neck as the fluoroscopy center, the C-arm was rotated at an interval of 10° between 0° and 170°, and the three aluminum foil paper models were taken for X-ray projection respectively. The X-ray angle with the smallest image of aluminum foil paper was taken as the appropriate X-ray angle of the surface. A penetrating model of the femoral neck internal fixation was made of three Kirschner wires penetrating through the anterior, posterosuperior and posteroinferior surfaces of femoral neck. The images of the penetrating Kirschner wires were observed through the traditional anteroposterior, lateral view and the three appropriate X-ray angle views obtained from the above test. Results The length of the three main surfaces accounts for 80. 95% of the circumference of the femoral neck. The anterior surface coronal angle was 18°, the posterosuperior surface coronal angle was 65°, and the posteroinferior surface coronal angle was 165°. The Appropriate X-ray angle of the three surfaces were 20°, 70° and 170° respectively. In the images of the three appropriate X-ray angles, the penetrating Kirschner wires of anterior surface, posterosuperior surface and posteroinferior surface of the femoral neck could be clearly observed respectively, while the penetrating Kirschner wire could not be completely found in the traditional anteroposterior and lateral images. Conclusion Traditional anteroposterior and lateral fluoroscopy can not accurately display the three-dimensional structure of femoral neck. By increasing the appropriate X-ray angle of 20°, 70° and 170°, the reduction quality and bony violation from internal fixation implants on the anterior surface, posterosuperior surface and posteroinferior surface of the femoral neck could be observed respectively.
