Objective To explore the correlation of rhinovirus infection and the morbidity of asthma in children.Methods The RV gene in nasopharyngeal secretion of 30 children with asthma acute exacerbation(asthma group),30 children in asthma clinical remission(remission group) and 30 healthy children (control group) were detected by reverse transcription-polymerase chain reaction(RT-PCR).The total serum IgE(T-IgE) was determined by chemiluminescence.The eosinophil(EOS) count (EOS%) of peripheral blood and lung function were also measured.Results The rhinovirus infection rate was 36.67% in asthma group and 3.33% in remission group.No rhinovirus was detected in control group.The rate of rhinovirus infections in asthma group was significantly highter than that in remission group and control group(?2=7.50,13.47 Pa0.05). FEV1% was (62.73?13.54)% in asthma rhinovirus infection and (86.42?17.78)% masthma with no rhinovirus infection.There was remarkable difference between 2 groups(F=14.553 P﹤0.05). The T-IgE was (836.32?44.801) kU/L and EOS% was 10.63?4.09 in asthma group with rhinovirus infection.The total IgE was (439.10?231.28) kU/L and EOS% was 5.04?2.64 in asthma group with no rhinovirus infection.There was significant difference between 2 groups(U=2.475,F=20.806 Pa0.05).Conclusions There is a close correlation between rhinovirus infection and acute attack of asthma(or worsening asthma) in children. Asthma exacerbations would be likely to happened easier because of rhinovirus infection in asthmatic children with high T-IgE.

Using in vitro everted gut to investigate the intestinal absorption of the extracts from Polygonum orientale at different concentration. UPLC-MS/MS was used to detect the content of protocatechuic acid, isoorientin, orientin, vitexin, cynaroside, quercitrin, kaempferol-rhamnoside in different intestinal segments, then compared the results with the absorption of chemical components of extractive P. orientale in each intestinal segments, and calculated the absorption parameter. We took the statistic analysis with SPSS statistic software. The influence significance of each factors were analyzed to describe the character of absorption. The absorption of each component is linearity in different intestinal segments and different dose, and the square of coeficient correlation exceed 0.95, which consistent with zero order rate process. The K(a) increase along with the raised dosage of the extractive P. orientale (R2 > 0.95), indicated it is the passive absorption; different intestinal segments have different absorption. And the absorption trend in intestinal is duodenum, jejunum, ileum are greater than the colon. As ingredients are selectively absorbed in intestinal sac, the everted intestinal sac method is selected to assess the intestinal absorption charcteristics of ingredients of extractive P. orientale.

AIM: To explore the role of NO in the induction of brain ischemic tolerance (BIT) by observing changes of NOS activity and NO_2-/NO_3- content following a transient cerebral ischemia. METHODS: The rat 4-vessel occluding brain ischemic model was used. 140 male Wistar rats were divided into sham, cerebral ischemic preconditioning (CIP), ischemic insult and CIP+ischemic insult groups. An occlusion of the 4 vessels for 3 min was normally used as CIP, and a relative long one for 10 min was used as ischemic insult. When CIP was followed by ischemic insult, the interval between them was 3 d. The CA1 region of the hippocampus of rats was dissected out at 0 h, 2 h, 16 h, 24 h, 36 h, 72 h and 7 d after the last time of ischemia to assay its NOS activity and NO_2-/NO_3- content. RESULTS: The NOS activity and NO_2-/NO_3- content began to increase at 16 h, peaked at 24 h and decreased to basal level at 36 h of reperfusion after CIP. The duration of the up-regulation of NOS activity and NO_2-/NO_3- content was much shorter than that of BIT, which usually takes place 1-7 d after CIP. The pattern of upregulation of the NOS activity and NO_2-/NO_3- content was similar to the CIP group, but the maximum (24 h) was much more than that in CIP group (P

Objective To study the effect of chest wall vibration therapy on bronchiolitis. Methods A total of 64 patients with bronchiolitis were divided into an experimental group and a control group, the former included 34 cases and the latter included 30 cases. The experimental group received both routine treatment and chest wall vi- bration, while the control group only received routine treatment. PaO_2, PaCO_2, SaO_2, Heart Rate (HR) and Respi- ration (R) were observed, respectively, in the experimental group and the control group at the beginning and the end of the third day. Time needed for expectoration and length of hospital stay in the two groups were observed. Results It was shown that PaO_2, PaCO_2, SaO_2 , HR, R were significantly improved at the end of the third day when compared with those at the beginning in both groups(P

This Synthetic Meintenance Liquor contains all kinds of nutritive substance that subsist the bacterium, and can preserve the bacterium for nearly ten years by providing energy needed by metabolism. It is a favorable culture medium to preserve bacterum long.

Objective To explore the relationship between serum homocysteine (Hcy) level before coronary angiography(CAG) and contrast induced nephropathy (CIN) after CAG.Methods We included 2264 cases of suspected coronary heart disease from May 2013 to May 2016 and all patients received CAG examination.According to whether CIN has developed or not after CAG, the patients were divided into the non-CIN group (n=2162) and the CIN group (n=102).We analyzed and compared the clinical baseline data, serum Hcy and creatinine (Cr) levels and the estimated glomerular filtration rate between the 2 groups eGFR.Results Patients in the non-CIN group were younger and with less comorbidities of diabetes and chronic kidney disease (all P<0.05).The volume of contrast media consumed in the non-CIN group was less than the CIN group [(122±21)ml vs.(147±24)ml, P=0.012).Hcy level in the non-CIN group (12.81±6.71) μmol/L was lower than that in the CIN group (21.74±11.9)μmol/L before CAG (P<0.05).No significant differences in serum Cr level and eGFR before CAG (P>0.05).At 72 hours after CAG, Cr level of the non-CIN group (69.34±19.54 μmol/L) was lower than that of the CIN group (87.34±21.38) μmol/L (P<0.05).eGFR was higher in the non-CIN group (79.34±19.54)ml/min than that in the CIN group (67.34±21.38)ml/min (P<0.05).Linear regression analysis showed that Hcy level before CAG were positively correlated with Cr level after CAG (r=0.547,P<0.01) and negatively correlated with eGFR after CAG (r=-0.271,P<0.01).Conclusions Hcy level before CAG can be used as one of an effective parameter to predict CIN.
