OBJECTIVETo investigate the proper anticoagulation intensity in patients after mechanical heart valve replacement in china.

METHODSThe anticoagulation therapy intensity and the complications in 480 patients after mechanical heart valve replacement were studied.

RESULTSThe follow-up rate was 89.17%, the total patient-years (Pty) was 2,110.04 years, the mean oral import warfarin dosage was (2.81 +/- 0.95) mg/day, and native warfarin dosage (2.38 +/- 0.46) mg/day. The mean PTR value of 2 116 samples was 1.43 +/- 0.26, and the INR value of 1 195 samples was 1.63 +/- 0.49. The total hemorrhage rate was 4.60% Pty, and the hemorrhage death rate was 0.38% Pty. The PTR and INR values were higher in the hemorrhage group than in the no-hemorrhage group. (t = 1.816, P < 0.05; t = 2.407, P < 0.01). The thromboembolism rate was 0.66% Pty, and the thromboembolism death rate was 0.05% Pty. There were 15 pregnancies in 14 women patients and no malformed newborns were found.

CONCLUSIONSThe most important complication of anticoagulation therapy after mechanical heart valve replacement is hemorrhage in china; The proper anticoagulation intensities of this group are INR 1.5-2.0 and PTR 1.3-1.5. It is beneficial to adopt the low intensity anticoagulation therapy for decreasing the death rate from hemorrhage, protecting pregnant women and newborns from hemorrhage and malformation, and improving the life qualities of the patients.

Objective:To analyze the characteristics of unmet needs and services of rehabilitation for people with intellectual disability (PIDs). Methods:A total of 250 654 PIDs had been sampled and administration data of unmet needs and services of rehabilitation at provincial level had been analyzed the characteristics of unmet needs and services of rehabilitation, and the related factors of needs and services were analyzed with Logistic Regression. Results:The rate of unmet needs reported by PIDs from high to low were nursing (47.8%), medicine (37.2%), functional training (26.1%), assistive devices (19.8%) and surgery (1.3%). The PIDs reported received service of rehabilitation, including nursing care (43.5%), medicine (29.3%), functional training (27.2%), assistive devices (19.6%) and surgery (0.8%). Logistic Regression Model showed that age and severity of disabilities significantly affect the reported the unmet needs and received services (P < 0.001). Conclusion:PIDs reported unmet needs mainly involved in the fields of nursing care, medicine and rehabilitation training and therapy. The unmet needs and received services had similar structure. It proposed to develop rehabilitation services tailored to PIDs' intellectual function and adaptive behaviors to develop services items and to deliver individualized and precise services.

BackgroundImmunosuppressive agents are still inefficient in preventing biopsy-proven acute rejection (BPAR) after expanded criteria donor (ECD) kidney transplantation. The aim of this study was to investigate the relationships between early immunosuppressive exposure and the development of BPAR.

MethodsWe performed a retrospective study of 58 recipients of ECD kidney transplantation treated with enteric-coated-mycophenolate sodium, tacrolimus (Tac), and prednisone. The levels of mycophenolic acid-area under the curve (MPA-AUC) and Tac Cwere measured at the 1 week and the 1 month posttransplant, respectively. The correlation was assessed by multivariate logistic regression.

ResultsThe occurrence rates of BPAR and antibody-mediated rejection were 24.1% and 10.3%, respectively. A low level of MPA-AUC at the 1 week posttransplant was found in BPAR recipients (38.42 ± 8.37 vs. 50.64 ± 13.22, P < 0.01). In addition, the incidence of BPAR was significantly high (P < 0.05) when the MPA-AUClevel was <30 mg·h·L at the 1 week (15.0% vs. 44.4%) or the Tac Cwas <4 ng/ml at the 1 month posttransplant (33.3% vs. 21.6%). Multivariable logistic regression analysis showed that the MPA-AUC at the 1 week (OR: 0.842, 95% CI: 0.784-0.903) and the Tac Cat the 1 month (OR: 0.904, 95% CI: 0.822-0.986) had significant inverse correlation with BPAR (P < 0.05).

ConclusionsLow-level exposure of MPA and Tac Cin the early weeks posttransplant reflects an increased acute rejection risk, which suggested that MPA-AUC <30 mg·h·L and Tac C <4 ng/ml should be avoided in the first few weeks after transplantation.
