ObjectiveTo explore the clinical efficacy and safety of autologous peripheral blood stem cell transplantation(APBSCT) in the treatment of pemphigus.MethodsTotally,3 patients with pemphigus vulgaris who responsed poorly to 6-month treatment with glucocorticoids or immunosuppressants or experienced aggrevation of disease and developed treatment-related complications,received APBSCT and were followed up for more than 5 years.There were 1 male and 2 females with an average age of 27.3(21-39) years.The mobilization program included cyclophosphamide (CTX) 4 g/m2,recombinant human granulocyte colonystimulating factors(G-CSF) and Rituximab 375 mg/m2,and the preconditioning regimen included intravenous CTX (50 mg/kg per day on days -6,-5,-4,-3),antithymocyte globulin at 2.5 mg/kg per day(on days -3,-2,-1 and 0) and Rituximab (600 mg/d on days 0 and 7).ResultsAll the 3.patients were successfully engrafted.The mean time for peripheral reconstruction:white blood cells 13.3 days (from day 11 to 16),platelet 16.3 days (from day 16 to 17).Monitoring of immunity indices and related antibodies showed no abnormality and the immune system was well reconstructed.No serious complications occurred during the follow up,and the patients' quality of life was obviously improved.ConclusionAPBSCT may be an effective and safe option for the treatment of pemphigus.

Objective To explore the feasibility of iodized Nang(bread) prepared with iodized salt and non-iodized rock salt as vehicle of iodine. Methods Two kinds of Nang, each of 10 respectively, were grilled with 30 g iodized salt water and non-iodized rock salt water mixed with 2 kg flour by the local cooker, then put inside of Nang oven using traditional methods of grilled Nang in Xinjiang. The samples were collected from different parts of Nang, including the layers facing oven wall and the fire, as well as inside of Nang. The method for determination of iodine in foodstuff by dry ashing As ~Ⅲ-Ce~(4+) catalytic spectrephotometry was used to determine iodine concentration in Nang. Results Iodine content in iodized and non-iodized Nang was (0.654 ± 0.076)mg/kg and (0.075 ± 0.022)mg/kg, respectively. In addition, Iodine content in two kinds of Nang was significantly different and iodine content of Nang with iodized salt was much higher than that with non-iodized rock salt(t = 13.520, P <0.01 ). Iodine content in two kinds of Nang from the layers facing oven wall and the fire, as well as inside of Nang were (0.700 ± 0.100), (0.064 ± 0.029)mg/kg; (0.647 ± 0.076), (0.070 ± 0.019)mg/kg; (0.659 ± 0.073), (0.073 ±0.030)mg/kg, respectively. Iodine content in two kinds of Nang of the same parts was significantly different(t =3.826,4.201,4.103, all P < 0.01 ). There was no significant difference of iodine content in different parts of the same kind of Nang(F = 0.220,0.190, all P > 0.05). Conclusions Grilled Nang with iodized salt contains sufficient iodine, and the iodine content of the same kind of Nang in different parts has no significant difference. Our studydemonstrated that Nang is a vehicle available for iodine fortification since Nang is very popular food for local population in Xinjiang.

U251 cell is a sensitive cell line to serum, which stops at G0 phase of cell cycle in no-serum medium, and recovers growth when the serum is added into no-serum medium. The cell can express corresponding proteins in different phase of cell cycle. Therefore it is very signification for the study of cell cycle regulation mechanism that explores these proteins. In this paper, the mouse antibody phage display library was added into the bottle in which the serum starvation U251 cells had been cultured, and the special antibody phages were absorbed. Then the absorbed antibody phages were amplified by adding E. coli TG1 and helper phage M13K07. Amplified antibody phages were added into bottle in which the serum cultured cell after serum starvation (follow named as serum recovered cells) were incubated, so that the cell absorbed the no-special antibody phages for the serum starvation cell and the special antibody phages were in supernatant. The remaining no-special antibody phages in the supernatant were discarded by repeating above program 3-4 times. The pure special antibody phages were gotten, and amplified by adding the host cell E. coli TG1 and helper phage M13K07. Then the host bacterium infected special antibody phage was spread on the plate medium with ampicillin, and the monoclonal antibody phages were gotten. Using same as above program, the monoclonal antibody phages absorbed specially for serum recovered U251 cells were obtained when the serum recovered cells instead of serum starvation cells and serum starvation cells instead of serum recovered cells. In this study, ninety-six positive monoclonal antibody phages that absorbed specially the serum starvation cells and eighty-two positive monoclonal antibody phages that absorbed specially the serum recovered cells were obtained. By using cell immunochemistry assay, two special signification antibodies were obtained. one (No.11) was the strong response in serum starvation cells, the other (No.2) was the strong response in serum recovered cells. The antibody No.2 had the distinctive response to the serum recovered cells in different incubation time (15min, 30min, 1h, 2h, 4h, 8h, 12h and 48h) after serum starvation. The results showed that No.2 antibody would be useful to research the factors of cell cycle regulation and apply to tumor diagnosis.

Objective To examine the benefits of ECMO for potential organ donors with hemodynamic instability after brain death.Methods Three brain-dead potential donors who presented with hemodynamic instability despite maximal medical management,finished a declaration of brain death,that were supported by extracorporeal circulation membrane oxygenation (ECMO).Results Donor organs,including six kidneys,and two livers,were harvested from the three donors under ECMO support,leading to 8 successful transplantations.The organs functioned well and the recipients made full recoveries.Conclusion Our experience indicates that ECMO allows for the maintenance of abdominal organ tissue perfusion without warm ischemia before organ procurement,providing sufficient time for safe organ donation procedures and reducing the risk of unpredictable cardiac arrest that could result in the donor death and graft loss.

OBJECTIVETo investigate the effect of Sini decoction (SND) in preventing vascular restenosis and protecting against oxidative stress after rabbit iliac artery balloon injury.

METHODSTwenty-four male New Zealand albino rabbits were equally randomized into control group, model group and SND group. Rabbits in the control group were fed with common forage, and those in the model and SND groups with high-fat diet. Two weeks later, the iliac arteries of the rabbits in the latter two groups were subjected to balloon injury. Four weeks after the operation, the rabbits were killed and the vascular structure was observed by scanning electron microscope and optical microscope, with the serum cholesterol level, superoxide dismutase (SOD) activity and malondialdehyde (MDA) level determined.

RESULTSScanning electron microscopy showed that the endothelial cell lining in the iliac artery of the control and SND group remain regular, but the arteries in the model group presented with desquamated and exposure of the collagen fibril beneath the endothelium. Optical microscope revealed narrowed vascular lumen, thicken intima and numerous arteriosclerotic plaques in the model group in comparison with the control group, whereas the vascular lumen and intima thickness remained basically normal in SND group. The levels of total cholesterol, low-density lipoprotein cholesterol and triglyceride were decreased with high-density lipoprotein cholesterol levels increased in SND group, which was not observed in the model group. The serum SOD activity was higher in the control group than in the model and SND groups, but SND group had higher serum SOD activity than the model group. The serum MDA level was lower in the control group than in the other two groups, but SND group had lower MDA level than the model group.

CONCLUSIONSND can alleviate intimal hyperplasia and vascular stenosis in injured rabbit iliac artery, possibly in relation to increased SOD activity and decreased lipid peroxidation as a result of SND treatment.

Objective To study the influencing factors of primary hypertension by investigating its prevalence in elderly patients of Deang nationality.Methods Nine hundred and thirty-nine elderly patients of Deang nationality were divided into hypertension group (n =353),prehypertension group (n=377) and control group (n=209).Their physical examination data were recorded and their blood pressure was measured.Results The detection rate of hypertension was significantly lower in elderly patients of Deang nationality than in those of the other nationalities in our country with their age ≥60 years (37.6％ vs 49.0％,P＜0.05).The detection rate of hypertension,isolated systolic hypertension and prehypertension increased with the increasing age (P＜0.05).Multivariate logistic regression analysis showed a cross interaction between economic level and alcohol drinking (P＜0.05) and a positive correlation of BMI,age,gender,divorce or widow,smonking,high salt diet with hypertension (P＜0.05).Conclusion The detection rate of hypertension is lower in elderly patients of Deang nationality than in those of the other nationalities in our country.Economic level,alcohol drinking,BMI,age,gender,divorce or widow,smoking,high salt and fat diet are the major risk factors for hypertension.However,regular eating of vegetables can reduce the risk of hypertension.

Objective To determine the awareness, treatment and control of hypertension and its determinants in the elderly hypertensive patients of Dean nationality so as to explore the associated determinants. Methods This was a cross-sectional, population-based survey. A total of 939 persons aged 60 years and older sampled by stratified sampling method from the elderly population of Dean nationality were examined from July to September 2016. Meanwhile, the data of medical history and examination were collected. Results There were 353 elderly patients with hypertension in the 939 subjects. The awareness, treatment and control of hypertension in the elderly hypertensive patients (EHP), which was 47.3％, 36.5％and 22.1％respectively, were higher than the results of previous national study and had the upward trends with the increasing age (<0.05) . In comparison with the reference group, EHP living in middle economic level area had the higher awareness, treatment and control of hypertension (<0.05) . The results of covariate-adjusted multilevel logistic regression model indicated that there was a cross-level interaction effect between middle economic level area and dyslipidemia on the awareness and treatment of hypertension respectively, and a cross-level interaction effect between middle economic level area and low fat diet on the control of hypertension ( <0.05) . The individual level covariates, age (OR=1.3412, 1.3144, 95％ CI 1.0217-1.7609, 1.0030-1.7225) and diabetes ( OR=2.6735, 2.3078, 95％ CI 1.0721-6.6672, 1.0240-5.2007), had the positive association with the awareness and treatment of hypertension;age (OR=1.4740, 95％CI 1.0034-2.1654), non-drinking (OR=3.2056, 95％CI 1.5554-6.6066) and low salt diet (OR=3.6969, 95％CI 1.7996-7.5946) had the positive association with the control of hypertension. Conclusion The awareness, treatment and control of hypertension in the EHP of Dean nationality were higher than those of the national level, and the dominant factors were economic level, age, dyslipidemia, diabetes, non-drinking, low fat diet and low salt diet, etc.

OBJECTIVETo investigate the effects of irbesartan for heart protection and on heart nitric oxide (NO) system in diabetic rats.

METHODSThirty adult male Wistar rats were randomly divided into three equal groups, namely control group, diabetes group and irbesartan group. Streptozotocin (STZ, 50 mg/kg) was injected to the abdomen to induce diabetes in the rats. After treatment for 12 weeks, the rats were sacrificed and the urine volume, body weight, ratio of heart to body weight, plasma glucose and glycosylated hemoglobin (HbA1c) were measured. NO levels in the serum and myocardium were determined. Inducible nitric oxide synthase (iNOS) expression was determined by immunohistochemistry, and iNOS mRNA detected by RT-PCR.

RESULTSUrine volume, ratio of heart to body weight, plasma glucose, HbA1C, NO levels in the urine, blood and myocardium in diabetic and irbesartan rats were significantly greater than those of normal controls (P<0.05). The ratio of heart to body weight and NO levels of urine, serum and heart tissue in rats of irbesartan group were significantly decreased as compared with those of diabetes rats (P<0.05). Myocardium iNOS mRNA and protein expression decreased significantly in irbesartan group, but not in diabetes group.

CONCLUSIONSThe abnormality in NO and iNOS mRNA expression might be related to diabetic cardiomyopathy. Irbesartan can decrease iNOS mRNA and protein expressions and reduce NO levels in STZ-induced diabetic rats.
