Objective:To investigate serum high sensitive C-reactive protein levels in type 2 diabetic patients with periodontal diseases,and to explore the relationship between serum high sensitive C-reactive protein levels and periodontal diseases in type 2 diabetic patients.Methods:The study included 20 type 2 diabetic patients with moderate or severe periodontal diseases,20 type 2 diabetic patients without periodontal diseases and 20 normal as control.Serum hs-CRP,HbA1c and other biochemical parameters were detected.Results:Compared with normal control and type 2 diabetic subjects without periodontal diseases,serum hs-CRP levels in type 2 diabetic patients with moderate or severe periodontal diseases were significantly increased.Serum hs-CRP levels were significantly elevated in type 2 diabetic patients without periodontal diseases compared with normal control subjects(P

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.

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 assess efficacy, infection rate and recurrence rate of tacrolimus prescribed in infants with steroid-resistant nephrotic syndrome (SRNS). Method From August 2011 to August 2014, 22 cases of SRNS infants (treatment group) received oral tacrolinms treatment, 0.1 to 0.15 mg/ kg per day and once every 12 hours were enrolled in this retrospective longitudinal study and were compared with 23 cases infant SRNS (control group) treated with high-dose methylprednisolone pulse therapy. Followed up for 1 year we analysed the data of proteinuria, lymphocyte count, proteinuria relapse and complication (infection, hyperglycemia) of the two groups’ patients at every point time. Results The pathology of the patients maintains of MCD, MsPGN, FSGS and IgM nephropathy so on. Follow-up to 6 months, the total remission rate 95.45% of treatment group was significantly higher than that in control group (60.87%). Follow-up to 6 months , 24 h urinary protein of the treatment group were respectively 67.88 mg/(kg·d) which were remarkably lower than base line [657.5 mg/(kg·d)], meanwhile which were obviously lower than the 6th month point of control group [305.55 mg/(kg·d)]. Lymphocyte counts had been done during the initial and the destination in the treatment group. Follow-up to 12 months, the CD4+ 795.16/uL, CD8+ 496.85/uL, CD19+ 358.23/uL had decreased observably than when at origin what was 2697.45/uL, 2265.63/uL, 1579.34/uL. Followed-up 1 year, the person-time of infection of treatment group existed superior to the control groups; The recurrence rate was 71.43% in treatment group, which compared with control groups (60.87%) without no significant difference. The treatment group with BG and CCr maintained stably. Conclusion Tacrolimus show its own advantages of reliable effect and less side-effect on the infant with steroid-resistant nephrotic symdrome associated with genes , but it could not lessen the relapse of the disease, and it′s long-term prognosis is still not very clear.

[Objective] To investigate the inhibitory effect of CTLA-4Ig fusion protein on atherosclerosis in the mice with an apolipoprotein-E gene defect fed on cholesterol diet.[Methods] Twenty-five male 10-week-old ApoE-/- mice were selected and fed on cholesterol diet for 4 weeks,5 out of which were executed at random as control group and their pathological sections were kept to observe the early fatty streaks.The other 20,divided into CTLA-4Ig treatment group,PBS group,IgG1 group,and blank group at random,5 in each.Three groups were given intraperitoneal injection of CTLA-4Ig (10 μg per time),PBS (100 μL per time),Rat-IgG1 (10 μg per time) respectively,twice a week,for 8 weeks.The blank group has no treatment.Followed by 8-week treatment,the whole aorta from the root to crotch of iliac artery was separated after anesthesia with the intraperitoneal injection of 1 % pentobarbital.Subsequently,the area ratio of plaque and lumen,the thickness ratio of endangium and tunica media,the lipid-soaking extent intra-plaque and the content of collagen fibrils and smooth muscle cells intra-plaque were analyzed by image-processing soft.[Results] After fed on cholesterol diet for 4 weeks,there were obviously atherosclerosis in the aorta in the ApoE-/- mice.There were typical atherosclerotic plaque in ApoE-/- mice fed on cholesterol diet after another 8 weeks.The area ratios of plaque and lumen in CTLA-4Ig group,PBS group,IgG1 group,and blank group were 0.27 ± 0.08,0.40 ± 0.08,0.43 ± 0.08,and 0.46 ± 0.10,and obviously increased than those in control group (0.05 ± 0.01,P ＜ 0.05).The thickness ratios of endangium and tunica media in four groups were 2.6 ± 0.6,6.0 ± 0.9,5.7 ± 0.8,and 5.9 ± 0.6 and obviously increased than those in control group (0.5 ± 0.1,P ＜ 0.05).The lipid-soaking extent intra-plaque in experimental groups were 26.0 ± 3.0,40.8 ± 5.7,40.6 ± 3.0,and 43.2 ± 5.7,and were obviously increased than those in control group (7.2 ± 1.4,P ＜ 0.05 ).It was found that the area ratio of plaque and lumen,the thickness ratio of endangium and tunica media,and the lipid-soaking extent intra-plaque in CTLA-4Ig group were significantly lower than those in PBS group,IgG1 group,and blank group (P ＜ 0.05),but there was no significant difference in those between the PBS group,IgG1 group,and blank group (P ＞ 0.05).The content of collagen fibrils in CTLA-4Ig group were 16.0 ± 1.1 and higher than those in PBS group,IgG1 group,and blank group (8.6 ± 1.2,9.2 ± 1.5,and 9.0 ± 1.3,P ＜ 0.05).The content of smooth muscle cells in plaque in CTLA-4Ig group were 11.8 ± 1.0 and higher than those in PBS group,IgG1 group,and blank group (7.8 ± 0.8,7.5 ± 0.9,and 7.3 ± 0.7,P ＜ 0.05).There was no significant difference in content of collagen fibrils and smooth muscle cells between the PBS group,IgG1 group,and blank group (all P ＞ 0.05).[Conclusion] CTLA-4Ig fusion protein could evidently inhibit the atherosclerosis progression and enhance the stability of plaque through increasing the content of collagen fibrils produced by smooth muscle cells intra-plaque in ApoE-/- mice fed on cholesterol diet.
