In critically ill patients,evoked potential(EP) testing is an important tool for measuring neurologic function,signal transmission,and secondary processing of sensory information in real time.EP potential measures conduction along the peripheral and central sensory pathways with longer-latency potentials representing more complex thalamocortical and intracortical processing.In critically ill patients with limited neurologic exams,EP provides a window into brain function and the potential for recovery of consciousness.Brainstem auditory EP and cortical event-related potentials are most commonly used in ICU.The primary indications for EP in critically ill patients are prognostication in anoxic-ischemic or traumatic coma,monitoring for neurologic improvement or decline,and confirmation of brain death.Historically,EP has been regarded as a negative prognostic test,that is,the absence of cortical potentials are associated with poor outcomes while the presence cortical potentials are prognostically indeterminate.In recent studies,the presence of middle-latency and long-latency potentials as well as the amplitude of cortical potentials is more specific for good outcomes.Event-related potentials,particularly mismatch negativity of complex auditory patterns,is emerging as an important positive prognostic test in patients under comatose.In infants,other than anoxic-ischemic or traumatic brain injury,brainstem auditory is also widely used in premature baby,bilirubin encephalopathy and detection of possible hearing loss.

OBJECTIVE: To investigate the possible beneficial effects of administration of Naoluo Xintong Recipe (NLXT) on the expression of HSP70 and bFGF in rats subjected to ischemia-reperfusion with qi deficiency and blood stasis syndrome. METHODS: We blindly randomized 40 male Wistar rats into 5 groups which were categorized as follows: (1); sham-operated group; (2) rats subjected to transient middle cerebral artery (MCA) occlusion with qi deficiency and blood stasis syndrome (control group); (3) NLXT-treated group; (4) NLXT-pretreated group; (5) Nao'an Capsule-treated group. Focal brain ischemia was induced by the intraluminal suture MCA occlusion method after qi deficiency and blood stasis syndrome had been made. The rats' brains were harvested at the 24h of reperfusion after 2h of MCA occlusion. The expression of HSP70 and bFGF was measured by by immunohistochemical staining. RESULTS: Strong HSP70 immunoreactivity in neurons was observed in NLXT-treated and NLXT-pretreated groups as compared to control group, and increased bFGF immunoreactivity in neurons was observed in the ischemic hemisphere in NLXT-pretreated group in comparison with the ischemic hemisphere in the control group (P<0.01). NLXT has stronger effects on HSP70 and bFGF than Nao'an Capsule. CONCLUSION: The neuroprotective effects of Naoluo Xintong Recipe may be related to its up-regulation of HSP70 and bFGF in the rat brain after focal cerebral ischemia.

Abstract: Objective　To observe the expression of peripheral blood stimulating molecules CD80 and CD86 in children with severe hand, foot, and mouth disease (HFMD), and to analyze the relationship between them and the therapeutic effects of children. Methods　The clinical data of 252 children with severe HFMD treated in Wuhan Hospital of Traditional Chinese Medicine from March 2017 to March 2021 were collected retrospectively. All children were treated with standardized treatment and the therapeutic effects was evaluated. The baseline data and laboratory test results of children were recorded, and the positive rates of CD80 and CD86 cells in peripheral blood were detected by flow cytometry. Logistic regression was used to analyze the relationship between the above indexes and the therapeutic effects of children. The receiver operating curve (ROC) was drawn to evaluate the value of the above indicators in predicting the therapeutic effects of children. Results　After standardized treatment, 48 children were ineffective, and 204 children were effective; the levels of serum CD80 [(2.28±0.84)% vs (2.12±0.33 )%] and CD86 [(3.35±0.96)% vs (2.23±0.41)%] in children were significantly lower than those at admission (t=2.851, 16.991; P<0.05). The levels of blood lactic acid, serum C-reactive protein (CRP), matrix metalloproteinase-9 (MMP-9), CD80 and CD86 at admission in the ineffective group were significantly higher than those of the effective group (P<0.05). Logistic regression analysis showed that the overexpression of serum CRP (OR=10.929), MMP-9 (OR=1.926), CD80 (OR=3.943) and CD86 (OR=1.947) at admission might be the risk factors of ineffective (all P<0.05). The results of the goodness of fit test for the model showed that, the goodness of fit was high (χ2=6.245, P=0.620); the model collinearity results showed that the variance inflation factors (VIF) values of each variable were <2, and there was no collinearity among the main indicators; the results of the individual independence test for the model showed that Durbin-Watson statistics (D-W)=0.279 and there was poor mutual independence among main indicators. ROC curve analysis showed that the area under the curve(AUC) of serum CD80 at admission in predicting the therapeutic effects of children was 0.762, the cut-off value was 2.390%, and the specificity, sensitivity and Youden index were 0.598, 0792 and 0.390 respectively; the AUC predicted by CD86 was 0.739, the cut-off value was 3.280%, and the specificity, sensitivity and Youden index were 0.510, 0.896 and 0.406 respectively; the AUC by combined prediction was 0.823, and the specificity, sensitivity and Youden index were 0.696, 0.833 and 0.529 respectively. Conclusions　Peripheral blood stimulating molecules CD80 and CD86 are involved in the progression of HFMD. Their overexpression may suggest a high risk of treatment ineffectiveness in children with severe HFMD. Early dynamic monitoring of the expression of serum CD80 and CD86 has a certain predictive value for the therapeutic effect of children.

Though there are different kinds of view on diabetic nutritional therapy for a long time,it is the basic treatment method on diabetes mellitus(DM).With some result of clinical research on diabetic nutritional therapy,people knew it more and more.To discuss new diabetic nutritional therapy is of great benefit to improve the curative effect and prolong the syndrome of DM.
