Objective To explore the diagnostic effect of serum level of cystatin C (CysC) on the renal function after neonatal asphyxia by detection of serum level of CysC, blood urea nitrogen (BUN) and serum creatinine (SCr) and calculation of glomerular filtration rate (GFR) in neonatal asphyxia. Methods The clinical data of 86 neonates with asphyxia (46 cases in mild asphyxia group,40 cases in severe asphyxia group) and 30 neonates without asphyxia (control group) were collected and the serum level of CysC, BUN and SCr were detected at 24 h to 72 h after birth. Results Serum levels of CysC, BUN and SCr were (1.97 ±0.33) mg/L, (4.97 ±2.15) mmol/L, (90.41 ±24.32) μmol/L in mild asphyxia group, (2.65 ±0.41) mg/L, (10.88 ± 3.31) mmol/L, (125.82 ± 45.44) μ mol/L in severe asphyxia group and (1.24 ± 0.35)mg/L, (4.25 ± 2.04) mmol/L, (58.41 ± 19.22) μmol/L in control group, respectively. The differences were significant among three groups and those values in mild and severe asphyxia groups were higher than those in control group. The sensitivity of CysC level to evaluate renal function in mild asphyxia group was better than BUN and SCr level (P＜ 0.05). In neonata] asphyxia, the serum level of CysC had negative correlation with GFR (P ＜ 0.01). Conclusions Serum level of CysC can be adopted to evaluate the renal function after neonatal asphyxia, which is better than BUN and SCr. With a higer level of CysC, the renal function injury may be worse.

Objective The aim of this study is to investigate the protective effect of inhibiting the open of mitochondrial permeability transition pore on neural stem cells. Methods In present study, four groups were set up, such as control, conditioned medium control group, Aβ1-42 group and CsA group. The levels of inflammatory mediators were detected by LiquiChip technique. The apoptotic rate of neural stem cells was detected by flow cytometry and the expression of caspase-3 was confirmed by western blotting. Results The levels of IL-6 and TNF-αwere 7.92 and 1.22 times higher than those in control group after Aβ1-42 acting on microglia for 96 h. After being exposed to inflammatory media, the apoptotic rate of neural stem cells reached 41.17%, these was significant increase compared to control (P<0.001);while the apoptotic rate were decrease significantly if the open of the mitochondrial permeability transition pore was inhibited. In the meantime, the activation of caspase-3 was reduced obviously. Conclution Inhibiting the open of mitochondrial permeability transition pore can markedly reduced the apoptotic rate of neural stem cells , and dramatically impaired the effect of inflammatory on the apoptosis of neural stem cells , suggesting that inhibiting the opening of the mitochondrial permeability transition pore have protective effect on neural stem cells.

In the paper, the study was reviewed on the infrared temperature characteristics of acupoints in recent 10 years. CNKI, WANFANG, VIP, SciVerse ScienceDirect and Springer databases were retrieved, with"infrared thermal imaging" and "acupoint" as the key words. The retrieving time was from January 1, 2006 to December 31, 2016. Totally, 468 relevant papers were searched and 169 papers of them were read carefully on acupoint infrared temperature. In terms of physiological condition, pathological condition and the stimulation methods such as acupuncture, moxibustion,, embedding therapy and cupping therapy, the general situation was reviewed on the infrared temperature characteristics of acupoints separately. It was found that the study on infrared temperature characteristics of acupoints in physiological condition was limited and the characteristics discovered were not enough to systematically review the physiological and physical properties of acupoints. The study in terms of the pathological condition objectively reflected the effects and rules of diseases. It was showed in the study of acupoint infrared temperature characteristics after stimulation that the changes of infrared thermal imaging tempe-rature at some specific region induced by different therapies and parameters might be used to deduce the potential mechanism and optimal parameters or schemes of intervention method and contributed to the formation and deve-lopment of quantitative diagnosis and treatment. The authors believe that the study on infrared temperature characteristics of acupoint provides the active significance in the exploration on the physiological and physical characteristics of acupoint, the effects and rules of diseases as well as the quantitative diagnosis and treatment.
