Objective To test the predicative roles of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1( KIM-1 ) for acute kidney injury (AKI) in critically ill patients. Methods Children from pediatric intensive care unit, were randomly divided into four groups:critically ill patients with AKI (group 1 ), critically ill patients with non-AKI (group 2) , chronic kidney disease group (group 3), healthy control group (group 4). 1.5 ml venous blood and urine specimens were collected and kept under-70°C. Serum creatinine , urine NGAL and urine KIM-1 were analyzed. Results Compared with group 2, group 3 and group 4, the urine NGAL and urine KIM-1 increases obviously in group 1 (P<0.05). There is no signiifcance of urine NGAL and urine KIM-1 between group2, group3 and group 4 (P>0.05). The concentration of urine NGAL increased more than 10 times of base-line level 2 days before the diagnosis of AKI under the Acute Kidney Injury Network standard with area under curve (AUC) 0.955 (P<0.05) , and the concentration of urine KIM-1 increased more than 5 times of base-line level 1 day before AKI with AUC 0.878 (P<0.05). The AUC was 0.984 (P<0.01) when they were combined. There is negative correlation between the increased times of urinary KIM-1, urinary NGAL and vally value of creatin clearance rate. Conclusions The concentrations of urine NGAL and urine KIM-1 are useful early biomarkers for predicting AKI, especially when they were combined.

AIM:To observe the characterization in neural cells derived from the hippocampus of embryonic rats and to examine the effect of myelin-associated glycoprotein(MAG) on the proliferation,differentiation and neurite growth of neural stem cells(NSCs).METHODS:The hippocampus cells of embryonic rats were isolated and cultured in vitro.The expressions of nestin and doublecortin,the marks of NSCs,were observed by immunocytochemical method.The rate of proliferating cells was examined by BrdU immunocytochemistry.The average neuronal neurite length and the percentage of differentiated neurons were detected by immunocytochemistry staining.RESULTS:The hippocampus cells of 16 days old embryonic rats had the characteristics of NSCs.The percentage of differentiated neurons(?-tubulin Ⅲ-positive cells) was 18.17%?2.79% and the average neuronal neurite length was(136.27?33.66)?m,seven days after the differentiation initiated in vitro in control group.After NSCs were treated with MAG-Fc(200 ?g/L),the percentage of differentiated neurons and the average neurite length were decreased,respectively,to 10.05%?3.42%(P0.05).CONCLUSION:MAG-Fc inhibits the differentiation and neurite growth of the NSCs,but has no effect on the proliferation.

The study is aimed to make the most of available space of Dendrobium officinale cultivation facility, reveal the yield and functional components variation of stereoscopic cultivated D. officinale, and improve quality, yield and efficiency. The agronomic traits and yield variation of stereoscopic cultivated D. officinale were studied by operating field experiment. The content of polysaccharide and extractum were determined by using phenol-sulfuric acid method and 2010 edition of "Chinese Pharmacopoeia" Appendix X A. The results showed that the land utilization of stereoscopic cultivated D. officinale increased 2.74 times, the stems, leaves and their total fresh or dry weight in unit area of stereoscopic cultivated D. officinale were all heavier than those of the ground cultivated ones. There was no significant difference in polysaccharide content between stereoscopic cultivation and ground cultivation. But the extractum content and total content of polysaccharide and extractum were significantly higher than those of the ground cultivated ones. In additional, the polysaccharide content and total content of polysaccharide and extractum from the top two levels of stereoscopic culture matrix were significantly higher than that of the ones from the other levels and ground cultivation. Steroscopic cultivation can effectively improves the utilization of space and yield, while the total content of polysaccharides and extractum were significantly higher than that of the ground cultivated ones. The significant difference in Dendrobium polysaccharides among the plants from different height of stereo- scopic culture matrix may be associated with light factor.

To systematically review the incidence rate of adverse drug reaction/event by Qingkailing injection. Such databases as the PubMed, EMbase, the Cochrane library, CNKI, VIP WanFang data and CBM were searched by computer from foundation to July 30, 2015. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and cross check data. Then, Meta-analysis was performed by using the R 3.2.0 software, subgroup sensitivity analysis was performed based on age, mode of medicine, observation time and research quality. Sixty-three studies involving 9,793 patients with Qingkailing injection were included, 367 cases of adverse reactions/events were reported in total. The incidence rate of adverse reaction in skin and mucosa group was 2% [95% CI (0.02; 0.03)]; the digestive system adverse reaction was 6% [95% CI(0.05; 0.07); the injection site adverse reaction was 4% [95% CI (0.02; 0.07)]. In the digestive system as the main types of adverse reactions/events, incidence of children and adults were 4.6% [0.021 1; 0.097 7] and 6.9% [0.053 5; 0.089 8], respectively. Adverse reactions to skin and mucous membrane damage as the main performance/event type, the observation time > 7 days and ≤ 7 days incidence of 3% [0.012 9; 0.068 3] and 1.9% [0.007 8; 0.046 1], respectively. Subgroup analysis showed that different types of adverse reactions, combination in the incidence of adverse reactions/events were higher than that of single drug, the difference was statistically significant (P < 0.05). This study suggested the influence factors of adverse reactions occur, and clinical rational drug use, such as combination, age and other fators, and the influence factors vary in different populations. Therefore, clinical doctors for children and the elderly use special care was required for a clear and open spirit injection, the implementation of individualized medication.

[ ABSTRACT] AIM:To investigate the effects of induced pluripotent stem cells-derived mesenchymal stem cells ( iPSC-MSCs) on cobalt chloride ( CoCl2 )-induced injuries of PC12 cells and its possible mechanism.METHODS:PC12 cells were exposed to CoCl2 to set up a chemical-induced cellular injury model and were cocultured with iPSC-MSCs.The cell viability was tested by CCK-8 assay.The apoptosis was measured by flow cytometry using Annexin V/PI staining.The mitochondrial membrane potential (MMP) was analyzed by flow cytometry using JC-1 staining.Immunofluorescence was employed to observe mitochondrial transfer from iPSC-MSCs to PC12 cells.RESULTS: Apoptosis of PC12 cells was in-creased and MMP of PC12 cells was decreased after exposed to CoCl2 at concentration of 400μmol/L for 24 h.Coculture of PC12 cells with iPSC-MSCs reduced the apoptosis and recovered the MMP of the PC12 cells.Tunneling nanotubes were formed between iPSC-MSCs and PC12 cells, through which the iPSC-MSCs transferred the mitochondria to the PC12 cells. CONCLUSION:iPSC-MSCs protect PC12 cells from CoCl2-induced injuries, which may be associated with the mitochon-drial transfer from iPSC-MSCs to PC12 cells.

Objective To analyze the peculiarity of infants steroid-resistant nephrotic syndrome (SRNS) and to assess the efficacy,side-effect and relapse of various of Tacrolimus prescribed in infants SRNS.Methods A total of 76 case of infant SRNS from August 2012 to August 2015 in Guangzhou Weman and Children's Medical Center grouped into oral Tacrolimus (TAC group),Methyprenisolone pulse therapy (MP group) and Methyprenisolong combined Cyclophosphamide(CTX) pulse therapy(MP + CTX group),were observed for 1 year,and the urine protein excretion,renal function (CCr),blood glucose (B G),urine retinal-binding-protein (URBP),lymphocyte count etc.were recorded and the situation of infection and relapse regularly were monitored regularly.The data were retrospectively analyzed by the statistical method.Results All SRNS children underwent kidney biopsy,and 36 cases of minimal change disease,32 cases of mesangial proliferative glomerulonephritis and 8 cases of focal segmental glome-rulosclerosis were contained in the patients.The pathological constituent ratios were not obviously different among these 3 groups.By 6-month follow-up,the complete remission ratio of TAC group was 63.64％,the total remission ratio was 95.45％,which were remarkably higher than those of MP group (26.09％,60.87％) and MP + CTX group (41.94％,74.19％);the urine protein excretion of TAC group [(7.8 ± 8.6) mg/(kg · d)] was distinctly lower than that of pretreatment and lower than that of MP group [(144.2 ± 118.3) mg/(kg · d)],and lower than that of MP + CTX group [(91.3 ± 87.4) mg/(kg · d)],and the difference was significant (F =22.69,P ＜ 0.05).The remission time of TAC group was about 2 months,that of other two groups was about 3 months.By 1-year follow-up,the lymphocyte counts including total T-cell (CD3 +),the helper T-cell (CD4 +) and the inhibited T-cell (CD8 +) of TAC group decreased obviously(all P ＜ 0.01),which were extremely lower than those of the M P group and MP + CTX group,and there were significant differences (all P ＜ 0.05).By 1-year follow-up,the person-time of infection existed superior to the other 2 groups,TAC group was compared with MP plus group,the rank sum was 348.5 (U =-3.69,P ＜ 0.01);compared with MP + CTX plus group,the rank sum was 369.5 (U =-4.18,P ＜ 0.01).During the observation the URBP of TAC group was distinctly higher than that of the MP group and the MP + CTX group [(13.77 ± 19.19) mg/L vs.(2.50 ± 1.77) mg/L,(2.06 ±3.63) mg/L],and the differences were significant(t =3.16,2.99,all P ＜0.05);the TAC group with BG and CCr maintained stably.Conclusions Tacrolimus shows its own advantages of more reliable effect and less side-effect in the infants with SRNS over MP therapy and MP combined CTX therapy,but it could not lessen the recurrence of the disease,and its long-term prognosis is still not very clear.
