Objective:To research the correlation of serum levels of IL-21,TGF-β1,TNF-α and IgA1 in children with allergic purpura and the purpura nephritis.Methods:57 cases with allergic purpura who were treated in our hospital from November 2015 to May 2016 were selected and 29 cases were diagnosed with general allergic purpura,and another 28 cases were diagnosed with purpuric nephritis.30 healthy children were selected as the control group.Then the serum levels of IL-21,TGF-β1,TNF-α,IgAl,immunoglobulin A (IgA),C3 and C4 between the three groups were observed and compared.Results:The serum levels of IL-21,TGF-β1,TNF-α,IgA1 and IgA in the purpuric nephritis group were higher than those of the control group and the general allergic purpura group,and the differences were statistically significant (P＜0.05);The serum levels of IL-21,TGF-β1,TNF-α,IgA1 and IgA in the general allergic purpura group were higher than those of the control group,and the differences were statistically significant (P＜0.05);There was no statistically significant difference about the C3 and C4 in the three groups (P＞0.05).Conclusion:The serum levels of IL-21,TGF-β1,TNF-α and IgA1 may be involved in the development ofhenoch-schonlein purpura and purpura nephritis.

Objective To observe the treatment effect of nicardipine for the presence of hypertension responses during thyroidectomy under cervical plexus nerve block.Methods Patient without hypertension before the operation was brought into if he received thyroidectomy under cervical plexus nerve block,and with the presence of hypertension responses during the operation,and without effect after injected innovar one dose or dolantin 50mg by vein when the blood pressure was over 160/90mmHg.20 patients according to the criterion mention above were dripped nicardipine 20?g/kg by vein.The SBP,DBP,MAP,HR,SpO_2 and ECG were recorded at 3min,5min,15min,30min,45min after injection and the side effects were also recorded.Results The SBP,DBP,MAP of all patients were fallen distinctly at 3min after injection,and reached lowest at 5min.The blood pressures were steady at other points.There was significantly difference between the point before and after injection(P

OBJECTIVE To explore the factors and effective preventive method of nosocomial lower respiratory(infection) after general anesthesia through trachea intubation.METHODS Using bacterial culture and identification technique to detect the samples collected from pipe and the sides of anesthetic machine,from disposable virus/(bacteri)a respiratory filter and buccal and bronchial secretion of patients with general anesthesia through trachea(intubation.) RESULTS Eight of 15 anesthetic machines without disinfection were with positive bacterial culture.All sides of virus/bacteria respiratory filter,and buccal and bronchial secretion of patients during operation had same(bacteria.) No bacteria growth was found in anesthetic machine and disposable virus/bacteria respiratory filter used after operation.The same bacteria as from buccal secretion were isolated from anesthetic machine in patients(without) using virus/bacteris respiratory filter.CONCLUSIONS The(results) showed the anesthetic machine is more easy to be contaminated by patients,and the reuse of anesthetic machine is an important factor for nosocomial(lower) respiratory infection after general anesthesia through trachea intubation.Intensifying periodic disinfection of(anesthetic) machine and using virus/bacteria respiratory filter can prevent contamination between anesthetic(machine) and patients and decrease nosocomial lower respiratory(infection) after operation.

Objective To observe the therapeutic effect of tramadol combined with fentanyl in patient controlled intravenous analgesia after nucleotomy of intervertebral disc.Methods 60 patients under general anesthesia,scheduled for nucleotomy of intervertebral disc,were randomly divided into three group(n=20):group tramadol(group T),group fentanyl(group F) and group tramadol+fentanyl(group TF).All patients were received patient controlled intravenous analgesia by loading dose+background dose+PCA bolus dose.The BP,HR,RR,VAS at 6,12,24,48h of postoperation were observed.The sedation score in 24h,average effective-press times and drug dose in 48h of postoperation were recorded.The incidence of nausea and vomiting during 24h of postoperation were observed.Results It had no significantly difference of BP,HR,RR,VAS among three groups.The average effective-press times of group TF (8?2) were significantly less than those of group T (14?3) and group F (12?3).The drug dose of 48h was tramadol (17.9?1.5)mg/kg(group T),fentanyl (16.8?1.5)?g/kg(group F) and tramadol (11.5?0.7)mg/kg+fentanyl (9.1?0.7)?g/kg(group TF).The drug dose of group TF showed significant difference compared with others.The sedation score in group F was the highest,it had significant difference compared with the other two group.The frequency of nausea and vomiting in group T was significantly more than that in others.Conclusion Tramadol or fentanyl gived alone can afford the same satisfied analgesic effect on nucleotomy of intervertebral disc.But there is high nausea-vomiting frequency in tramadol and strong sedation frequency in fentanyl.Tramadol combined with a little opioid fentanyl can afford more satisfying analgesic effect,and is provided with advantage in less drug and side-effect.

The non-invasive brain-computer interface (BCI) has gradually become a hot spot of current research, and it has been applied in many fields such as mental disorder detection and physiological monitoring. However, the electroencephalography (EEG) signals required by the non-invasive BCI can be easily contaminated by electrooculographic (EOG) artifacts, which seriously affects the analysis of EEG signals. Therefore, this paper proposed an improved independent component analysis method combined with a frequency filter, which automatically recognizes artifact components based on the correlation coefficient and kurtosis dual threshold. In this method, the frequency difference between EOG and EEG was used to remove the EOG information in the artifact component through frequency filter, so as to retain more EEG information. The experimental results on the public datasets and our laboratory data showed that the method in this paper could effectively improve the effect of EOG artifact removal and improve the loss of EEG information, which is helpful for the promotion of non-invasive BCI.

OBJECTIVETo research the central molecular mechanism of gastric motility in functional dyspepsia (FD) rats treated with electroacupuncture (EA) at and points of stomach.

METHODSA total of 30 SD rats were randomized into a blank group, a model group, a Zhongwan+Weishu group, a Weishu group and a Zhongwan group, 6 rats in each group. FD rats were established by moderate clipping tail infuriation and irregular feeding except in the blank group. EA was used at "Zhongwan"(CV 12),"Weishu"(BL 21), and"Zhongwan"(CV 12) +"Weishu"(BL 21) in the corresponding groups for 7 days, once a day, and 20 min a time. No intervention was used in the blank and model groups. Grabbing and fixation were applied in the model group. Gastric antrum motion range and frequency were recorded by gastrointestinal pressure transducer. The expression of subunit NR1 of N-methyl-D-aspartate recepter (NMDAR) in dorsal motor nucleus of the vagus (DMV) was determined by Western blotting. The content of serum nitric oxide (NO) was measured by ELISA.

RESULTSCompared with the blank group, the gastric antrum motion range and NR1 in the DMV decreased and the serum NO content increased in the model group (all <0.05). Compared with the model group, the gastric antrum motion range and NR1 in the DMV increased and the serum NO content decreased in the three EA groups (all <0.05). Compared with the Zhongwan and Weishu groups, the gastric antrum motion range and NR1 in the DMV increased in the Zhongwan + Weishu group (all <0.05). Compared with Zhongwan + Weishu and Zhongwan groups, the expression of NO in the Weishu group decreased (both <0.05). The gastric antrum motion frequency among the 5 groups had no statistical significance (all >0.05).

CONCLUSIONEA at the and points can regulate the gastric motility in FD rats which may be by modulating the activity of NMDAR in the central DMV region, thus regulating the serum NO content.
