Objective To explore the most suitable equation in accessing renal function for the elderly type 2 diabetic patients, and its clinical utility in combination with hypersensitive C-reactive protein (hsCRP). Methods The new Cystatin C-based equations for estimated glomerular filtration rate (Cys-eGFR) and conventional predictive equations were compared with isotopic GFR (iGFR) by linear regression analysis, paired t-test, Bland and Altman procedures and non-parametric receiver operating characteristic (ROC) curves. The new Cys-eGFR equation and hsCRP were also incorporated for detecting renal disease in this population. Results The new Cys-eGFR equation had a better relativity with iGFR (r= 0.767, P<0.001), a less bias (bias: 0.0007, P>0.05), a higher conformance (2SD: 21.56), higher sensitivity (90.7%) and specificity (88.6%) for diagnosing moderate decrease in renal function. There was a negative relationship between the new Cys-eGFR and hsCRP (r=-0.655, P<0.01). When the new Cys-eGFR was 67.06 ml· min-1 ·1.73 m-2 and hsCRP was 5.65 mg/L, the combination of Cys-eGFR and hsCRP was better than the combination of serum creatinine and urine albumin/creatinine ratio in screening stage 3 chronic kidney disease (95%vs.46%). Conclusions The combination of new Cys-eGFR equation and hsCRP may screen an early decrease of moderate GFR.

Objective To investigate the effects of co-exposure to LPS and heat on plasma tumor necrosis factor-? (TNF-?) and interleukin-6 (IL-6) in rats. Methods Eighty male pathogen-free Wistar rats were randomly assigned to 4 groups: saline-injected normothermic control (group C), saline-injected heat exposed (group H), LPS-injected normothermic control (group L), LPS-injected heat exposed (group HL). Rectal temperature (Tr), heart rate (HR), mean arterial pressure (MAP), and respiratory rate (RR) were continually monitored. Plasma levels of TNF-? and IL-6 were determined at 0, 40, 80, 120 min after treatment. Results The rats in group HL displayed significantly higher values of Tr , HR , and RR and lower values of MAP than that of group C at 120 min. There was a significant difference in the values of HR and MAP between group HL and the other 3 groups at the same time point. The rats in group HL displayed an early rise in levels of plasma TNF-?, IL-6 at 40 min. The significant elevation of the peak TNF-? level at 80 min in group HL was observed. Plasma IL-6 hyperexpression was shown in rats in group HL which was significantly higher than the other 3 groups at the same time point. Conclusion Co-exposure to LPS and heat induces the rat to develop and augment systemic inflammatory response syndrome.

BACKGROUND:The studies have shown that the mesenchymal stem cel s derived from bone marrow and umbilical cord can be continuously cultured in vitro, and maintain the characteristics of stem cel s. The mesenchymal stem cel s can differentiate into hepatocyte-like cel s after“cocktail”induction by various cytokines. OBJECTIVE:To further identify whether umbilical cord-derived mesenchymal stem cel s in vitro co-cultured with normal hepatocytes can differentiate into hepatocyte-like cel s, and to investigate the differentiation method. METHODS:Mesenchymal stem cel s were isolated from human umbilical cord with adherent method, and the surface markers of umbilical cord-derived mesenchymal stem cel s were detected with flow cytometry. The umbilical cord-derived mesenchymal stem cel s were co-cultured with liver LO2 cel s without adding exogenous inducers. The expressions of alpha-fetoprotein, albumin and human cytokeratin 19 mRNA of hepatocyte specific markers were detected with reverse transcription PCR at 7, 14 and 21 days after culture, and periodic acid-Schiff staining was used to identify the functions. RESULTS AND CONCLUSION:Mesenchymal stem cel s could isolated from human umbilical cord successful y, showing fibroblastic morphology and adherent cel characterization. Among these cel s, 96.02%cel s were CD29 positive cel s and 96.6%cel s were CD105 positive cel s. The percentage of CD34 negative cel s was 99.65%. The percentage of CD105+CD29+double positive cel s was 94.84%. The mRNA of alpha-fetoprotein was found on the 7th day after co-cultured with LO2 cel s, and the mRNA of albumin and human cytokeratin 19 were found on the 14th day. After co-cultured for 21 days, the alpha-fetoprotein mRNA could not be observed in the co-culture group. The expressions of albumin and human cytokeratin 19 were increased at 14 days. After co-cultured for 21 days, the glycogen staining was positive. Umbilical cord-derived mesenchymal stem cel s can differentiate into hepatocyte-like cel s after co-cultured with normal hepatocytes.

Natural killer (NK) cells are a part of the innate immune system, providing the first line of defense against pathogens and cancer cells. NK cells have multiple ways to kill tumor cells and have a stronger anti-tumor effect than T cells. NK cells-based adoptive cell immunotherapy has gradually shown its great advantages in the treatment of hematologic malignancies. This paper reviews the physiology of NK cells, the mechanism of chimeric antigen receptor (CAR)-NK cells, and the current clinical application of CAR-NK cells.
