The participants comprised ABO incompatibility(n = 1); positive cross-match and/or presence of donor specific antibody(n = 5). The average time required from registration in kidney paired donation(KPD) registry to find suitable donors was 45 d and time required to perform transplants after legal permission was 2 mo. RESULTS Graft and patient survival were 100%, and 100%, respectively. One patient had biopsy-proven acute borderline T cell rejection(Banff update 2013, type 3). Mean serum creatinine was 0.8 mg/dL at 9 mo followup. The waiting time in KPD was short as compared to deceased donor KT. CONCLUSION We report first non-simultaneous, single center, 6-way kidney exchange transplantation from India. Our experience will encourage other centers in India to undertake this practice.展开更多

METHODS Fasting blood samples were taken from diabetic patients attending our clinic for their regular annual examination, including laboratory measurement of serum creatinine and eGFR.RESULTS Our results indicated an overall excellent agreement in CKD staging(kappa = 0.918) between the Jaffé serum creatinine-and enzymatic serum creatinine-based CKDEPI-eGFR, with 9% of discordant cases. As compared to the enzymatic creatinine, the majority of discordances(8%) were positive, i.e., associated with the more advanced CKD stage re-classification, whereas only 1% of cases were negatively discordant if Jaffé creatinine was used for eGFR calculation. A minor proportion of the discordant cases(3.5%) were re-classified into clinically relevant CKD stage indicating mildly to moderately decreased kidney function(< 60 m L/min per 1.73 m^2). Significant acute and chronic hyperglycaemia, assessedas plasma glucose and Hb A1 c levels far above the recommended glycaemic goals, was associated with positively discordant cases. Due to a very low frequency, positive discordance is not likely to present a great burden for the health-care providers, while intensified medical care may actually be beneficial for the small number of discordant patients. On the other hand, a very low proportion of negatively discordant cases(1%) at the 60 m L/min per 1.73 m^2 eGFR level indicate a negligible possibility to miss the CKD diagnosis, which could be the most prominent clinical problem affecting patient care, considering high risk of CKD for adverse patient outcomes. CONCLUSION This study indicate that compensated Jaffé creatinine procedure, in spite of the glucose-dependent bias, is not inferior to enzymatic creatinine in CKD diagnosis/staging and therefore may provide a reliable and cost-effective tool for the renal function assessment in diabetic patients.展开更多

Our preliminary results throw light on the nature of NSE reaction produced colors, under light microscope, which were different in various sections for different air drying time length. The reaction product on the slices of the convoluted tubules of chick embryonic kidney was bright yellow after less than 30 min air drying time length, brown after 1.5～2 h air drying time length and black after more than 3 h of air drying. The color change process of NSE precipitates from bright yellow to black is progressive. The phenomennon has not been described previously.展开更多

Oligodendrocyte precursor cells are neural stem cells that are important for myelin repair and regeneration. In the present study, Erhuang capsule effectively improved clinical symptoms and neurological function scores, reduced mortality and promoted recovery of neurological functions of mice with experimental autoimmune encephalomyelitis. The mechanism of action involved significant increases in oligodendrocyte precursor cell proliferation in specific regions of the brain and spinal cord, increased oligodendrocyte lineage gene 2 expression and enhanced oligodendrocyte precursor cell differentiation.展开更多

Methods: Totally 72 healthy Japan long-ear white rabbits, aged 4 months, were randomly divided into 6 groups, blank group (A), model group (B), high dose Chinese herb group (C), middle dose Chinese herb group (D), small dose Chinese herb group (E), aminoglucose hydrochloride capsule control group (F), 12 rabbits in each group. All the rabbits in the groups, except the group A, were fixed with plaster cast for six weeks to establish rabbit knee osteoarthritis. At the same time of modeling, the different doses of Juanbi Capsules and aminoglucose hydrochloride capsule were administrated intragastrically in the group C, D, E, F, respectively, for 4 weeks, for preventive treatment. In the group B, the rabbit was administrated intragastrically with equal volume of normal saline to the medication groups, twice each day, in the morning and the evening, and in the group A, nothing was administrated. After modeling for 6 weeks, the joint fluid was taken and TNF-α, IL-1 and IL-6 contents were detected with ELISA method, and the articular cartilage was taken for macroscopic and microscopic examinations. Results: In all the preventive treatment groups, the articular cartilage color changed to varying degrees with formation of osteophyte and bone cyst, superficial erosion on the chondral articular surface, and the cartilage defect reached to the mid layer in a part of specimens with cartilage exfoliation, but which in the extent were significantly lower than those in the model group. There were significant differences between the group A and B in TNF-α , IL-1 and IL-6 contents in the joint fluid (P<0.05), indicating that the modeling is successful; and there were significant differences as group B compared with the group C,D, E, F, showing that TNF-α , IL-1 and IL-6 contents are decreased in all the medication groups; and significant differences between group C, D, E suggests that the increase of Chinese herb doses strengthened the effect of reducing TNF-α , IL-1 and IL-6 contents in joint fluid. Conclusion: The Juanbi Capsule prevents osteoarthritis possibly through decreasing serum TNF-α, IL-1 and IL-6 contents.展开更多
