Methods The parameters of blood flow and frequency-spectrum of SMA and IMA in 16 cases of patients with UC were observed before and after treatment, and 10 healthy volunteers served as control. Results The parameters of blood flow of IMA in patients with left half colon UC (9 cases) and all colon UC (7 cases) significantly changed after treatment(P

A total of 160 elderly patients with Ⅰ -Ⅲ essential hypertension were enrolled in the study and examined with high-frequency color Doppler ultrasonography (America ATL Company HDI3500 type color ultrasonoscope). Common carotid artery (CCA), internal carotid artery and external carotid artery (ECA) were detected, including carotid artery intima-media thickness (CAIMT) and hemodynamic index. At the same time, 110 healthy elders were taken as contrast group. With the increased degree of hypertension, CAIMT was gradually enhanced and the most obviously in patients of grade Ⅲ hypertension. There were significant differences in grade Ⅲ, Ⅱ, Ⅰ and contrast group (P

【Objective】To observe the dynamic interference of cellular endotoxin specific receptors of Toll-like receptor 4(TLR4) mRNA and nuclear factor ?B p65(NF-?B p65) in rats with damp-heat syndrome of seasonal febrile disease by Ganlu Xiaodu Dan(GXD),and to explore the therapeutic mechanism of prescriptions with the actions of clearing heat and resolving dampness.【Methods】Wistar rats were randomized into 3 groups: A(normal control),B(models established by feeding of high-fat diet and colon bacillus under the high-temperature and high-humidity condition),and C(rat models treated with GXD).Reverse transcription-polymerase chain reaction(RT-PCR) analysis was used to detect the TLR4 mRNA level in hepatic macrophages and immunohistochemical method was used to detect the activation of NF-?B p65.【Results】The expression of TLR4 mRNA and NF-?B p65 was increased gradually in group B 6,12 and 24 hours after infection with colon bacillus,and the differences were significant,indicating that the expression of TLR4 mRNA and NF-?B p65 increased with the prolongation of disease course.In group C,TLR4 mRNA expression was decreased in different time points after infection,the difference of TLR4 mRNA expression 12 and 24 hours after infection was significant as compared with group B and group A(P

The effect of globular adiponectiin (gAd)on the function of NIT-1 cells under high glucose medium was investigated. The results showed that gad could completely block the increase of NADPH oxidase components p47phox expression and recover mRNA expression of pancreatic duodenal homeobox-I ,paired box gene 6,glucose transpoter 2,and glucokinase except neurogenic differentiation factor 1 (P<0.05 or P<0.01). Whereas,impaired insulin secretion and mRNA expression at high glucose concentration were not significantly improved by gAd.

were measured at the end of inspiratory.ResultsThe differences of following parameters were statistically significant between the healthy control group, mild PH group, moderate PH group and severe PH group: velocity time integral of ventricular systolic wave (SVTI), velocity time integral of ventricular diastolic wave (DVTI), AR, AR/S, ARVTI/SVTI, AR/(S+D), ARVTI/(SVTI+DVTI,F=2.940, 2.838, 3.373, 7.681, 3.478, 12.052, 4.806;P<0.05,<0.05,<0.05,<0.01,<0.05,<0.01,<0.01). Correlation analysis showed that ratio of AR/(S+D) was positively correlated with pulmonary artery mean pressure (r= 0.575,P<0.01). ConclusionsThe ratio of AR/(S+D) of MHV Doppler flow spectra was correlated with pulmonary artery mean pressure. The ratio increased along with the increasing of pulmonary pressure in CHD patient. The Doppler echocardiographic detection of MHV flow had a certain reference value for the diagnosis of PH. The ratio of AR/(S+D) could be a new non-invasive parameter for evaluating PH.

BACKGROUND:Traditional therapeutic methods of diabetes combined with lower limb artery obturation showed poor outcomes such as drug or intervention.Stem cell transplantation is a new method to treat this disease in recant years,and has obtained good outcomes in the clinic.Evaluating the therapeutic outcomes of stem cell transplantation has great damage and cost much.Thus,color Doppler ultrasound is used to examine non-invasion in the artery of the lower extremity,which shows important clinical value.OBJECTIVE:To evaluate improvement of lower extremity artery lesion following autologous peripheral blood stem cell transplantation using color Doppler ultrasound,and to compare with results of angiography.METHODS:A total of 41 patients diagnosed as having diabetes combined with lower limb artery obturation were included.Following administration of recombinant human granulocyte-colony stimulating factor(rhG-CSF)(150 μg/d)for 5 days,peripheral blood mononuclear cells(PBMNCs)were mobilized and harvested by using a separator at day 5 to prepare stem cell suspension,and which were injected intramuscularly in the diseased extremities(3×109 per limb).The clinical and laboratory findings were monitored every week for 3 months to 1 year following stem cell transplantation.RESULTS AND CONCLUSION:After stem cell transplantation,severe pain lameness,local cool-feeling and ulcer were significantly improved,and ankle-brachial index was increased obviously(P＜0.01).Color Doppler ultrasonography measurement showed that peak systolic velocity in diseased extremities was significantly increased post-transplantation(P＜0.01).Following transplantation,blood flow of the lower limb arterial canal was improved to different extents;collateral vessels were increased surrounding obstructed artery and in muscles.Spiral CT for new collateral vessel formation were showed increased.No related complication or adverse effects were observed in 41 patients during observation.Results indicated that color Doppler ultrasound can exactly rapidly examine and assess blood transport improvement in the lower limbs following stem cell transplantation,which is identical to results from angiography.It also provides reliable evidences for the diagnosis on the transplantation of stem cells for the treatment of diabetes combined with lower limb artery obturation.

Objective: To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO. Methods: Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×10⁹/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×10⁹/L. Results: A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×10⁹/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×10⁹/L) at 4^th week, 8^th week and 12^th week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×10⁹/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild. Conclusion Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.

Objective: To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m², 10 mg/m² or 12 mg/m² as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) . Methods: A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m²) as induction chemotherapy in newly diagnosed patients of adult AML. Results: Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (P<0.001) . After adjusted for age, blast ratio of bone marrow, FAB classification and risk stratification, the odds ratios (95% CI) of IDA 10 mg/m² group and IDA 12 mg/m² group were 0.49 (0.34-0.70) and 0.36 (0.18-0.71) , as compared with the IDA 8 mg/m² group (P<0.001, P=0.003) . In the intermediate and favorable groups, CR rates was 76.5% (163/213) , 86.9% (506/582) and 86.1% (68/79) in different doses of IDA (P=0.007) . Interestingly, IA regimen with IDA 10 mg/m² was the only beneficial factor affecting CR in this group after adjusted for age, blast ratio of bone marrow and FAB classification[OR=0.47 (95% CI 0.31-0.71) , P<0.001]. CR rates in adverse group was 50.0% (18/36) , 60.6% (43/71) and 81.8% (18/22) respectively (P=0.089) . However, the odds ratios (95% CI) of IDA 12 mg/m² when compared with the IDA 8 mg/m² was 0.22 (0.06-0.80) , after adjusted for age, blast ratio of bone marrow and FAB classification. The median time (days) of neutrophil count less than 0.5×10⁹/L in IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 14 (11-18) , 15 (11-20) and 18 (14-22) , respectively (P=0.012) and of platelet count lower than 20×10⁹/L were 14 (7-17) , 15 (11-20) and 17 (15-21) , respectively (P=0.001) . The incidences of lung infection in the three groups were 9.8%, 13.5% and 25.2%, respectively (P<0.001) . Conclusions For young adult patients (aged 18-60 years) with AML in China, intensifying induction therapy with idarubicin 10 mg/m² is clinically superior to IDA 8 mg/m² and IDA 12 mg/m² in favorable intermediate AML subgroup. However, idarubicin 12 mg/m² is more suitable to adverse AML subgroup.
