Objective To explore the associated rules between western medicine and traditional Chinese medicine (TCM) on urinary tract infection (UTI) with text mining technique.Methods The data set on UTI was downloaded from CBM database.The regularities of Chinese patent medicines (CPM),western medicines and the combination of CPM and western medicines on UTI were mined out by data slicing algorithm.The results were showed visually with Cytoscape2.8 software.Results The main function of CPM was focused on clearing heat and removing toxicity,promoting diuresis and relieving stranguria.For western medicine,antibacterial agents was often used and it was also frequently used together with CPM such as Sanjinpian.Conclusions Text mining approach provides an important method in the summary of the application regularity for disease in both TCM and western medicine.

Objective To study the epidemiological characteristics and influencing factors of hand-foot-mouth dis-ease(HFMD)outbreaks in kindergartens,so as to provide reference for control and prevention of HFMD. Methods Papers published between 2009 and 2015 about HFMD outbreaks in kindergartens were retrieved from Wanfang database and China National Knowledge Infrastructure (CNKI),then collected papers were analyzed. Results Data about 39 cases of HFMD outbreaks were obtained,35 cases occurred in 2008-2012,1 case occurred respectively in 2007,2013,2014,and 2015. 33.34% and 23.08% of outbreaks occurred in May and April. Out-breaks lasted 5-52 days,with a median of 11 days,30.77% of outbreaks lasted more than 2 weeks. The attack rates of the whole kindergartens were 1.90% -39.74% ,attack rates of whole kindergartens were 5% -15% a-mong 65.79% of outbreaks,attack rate of whole kindergartens was >20% among 13.16% of outbreaks. 85.71%of outbreaks involved more than 20% of classes,25.71% of which involved all classes. Both EV71 and CoxA16 caused HFMD outbreaks in kindergartens,two kinds of viruses were both detected in some outbreaks;there were no significant difference in attack rate of whole kindergartens,attack rate of classes with highest incidence,class in-volving rate,and duration of epidemic between EV71 and CoxA16 epidemic groups(all P>0.05).Conclusion Once an HFMD outbreak occurred in a kindergarten,epidemic intensity would be high,both EV71 and CoxA16 can cause HFMD outbreak. There is no obvious correlation between class size and attack rate.

Objective:To compare the immediate therapeutic effect and safety between esmolol and lanatoside in con-trolling ventricular rate for patients with rapid atrial fibrillation.Methods:A total of 72 patients with rapid atrial fi-brillation (ventricular rate ≥120 beats/min)were randomly and equally divided into esmolol group and lanatoside group.Esmolol group received first dosage of 0.5 mg/kg intravenously for 1 min,then were observed for 5 min,if ventricular rate still >100 beats/min or decreased <20%,the 0.5 mg/kg esmolol was appended,meanwhile main-tained by 0.05mg·kg-1 ·min-1 via micro pump at first,maintenance dose can increase to a maximum 0.3mg· kg-1 ·min-1;lanatoside group received first dosage of 0.4mg or 0.2mg slow intravenous injection,if ventricular rate still >100 beats/min or decreased<20%,the another 0.2mg was appended.The onset time and adverse reac-tions were recorded after administration.Results:Compared with lanatoside group,there was significant reduction in mean onset time [(39.2±8.7)min vs.(5.6±3.1)min]in esmolol group,P<0.01;compared with before adminis-tration,there was significant decrease in ventricular rate in two groups after administration,P<0.05 or<0.01. On 2h af-ter administration,compared with lanatoside group,there was significant increase in decreasing range of ventricular rate (29% vs.39%)in esmolol group,P<0.05. The total effective rate and adverse reaction rate was no significant difference (P>0.05)between two groups.Conclusion:Intravenous using esmolol is efficient and safe,and it can be regarded as pre-ferred therapy to control ventricular rate in patients with rapid atrial fibrillation.

This study was aimed to establish an analysis method of amentotaxus biflavone distribution in rats' tissues, including the heart, liver, spleen, lungs, kidney, brain, stomach, large intestine and small intestine, in order to investigate its distribution characteristics in tissues after rats gavaged with amentotaxus biflavone. HPLC-UV was employed to determine contents of amentotaxus biflavone in rats' tissues. The intragastric administration dose of amentotaxus biflavone was 500 mg·kg-1. Rats were sacrificed by cervical dislocation 10 min, 0.5, 1, 2, 4, 8, 12 h after intragastric administration. Tissues of the heart, liver, spleen, lungs, kidney, stomach, large intestine, small intestine and brain were removed and dissected immediately. Distribution of amentotaxus biflavone in each tissue was determined after processing. The results showed that tissue in different range had a good linear range. The lowest detection limit was 0.125 ng. The RSD of intra and inter-day was less than 10%. The absolute recovery rate of amentotaxus biflavone in each tissue was between 75.07% and 89.80%. The relative recovery rate was between 92.00% and 107.00%. Amentotaxus biflavone in each tissue was stable in different tissues in refrigerator of -20° C for 15 days. It was concluded that there were relatively large concentration differences of amentotaxus biflavone in different tissues. After intragastric administration, amentotaxus biflavone was mainly distributed in the stomach, large intestine, small intestine, liver and kidney, and then the heart, lungs and spleen. It also distributed in brain tissues through the blood-brain barrier.

OBJECTIVE To investigate the effects and its underlying mechanis m of bisphenol-A (BPA)exposure on spine and synapse formation in detate gyrus (DG)area of hippoca mpus during criti-cal develop mental period.METHODS Sprague-Dawley(SD)rats were injected intraperitoneally with BPA (50,250 and 500 μg·kg -1·d -1 )fro m postnatal day 7 (PND7)to PND14.Dendritic spine morphol-ogy in DG area was exa mined using Golgi-Cox staining method and determined with I mage J software. Western blotting method was e mployed to test the Wnt related proteins.RESULTS The spine density and the average spine head size in BPA exposed groups significantly decreased in a dose-dependent manner when co mpared to control group(P<0.05).Meanwhile,Wnt related proteins were affected dur-ing BPA exposure.Specifically,the percentage of phosphorylated β-catenin increased following BPA ex-posure (P<0.05),whereas Wnt7a expression level was significantly decreased and Wnt5a expression level increased (P<0.05).CONCLUSION Wnt signaling pathway plays an i mportant role in BPA-in-duced i mpairments in spine and synapse formation.

Objective To observe the attenuated and synergistic effect of meteorism tablets in treating HBeAg-positive chronic hepatitis B patients. Methods Eighty patients of HBeAg-positive chronic hepatitis B were randomly divided into treatment group (meteorism tablets combined with telbivudine) and control group (telbivudine), and treated for one year. The changes of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the negative rate of HBV-DNA, the negative rate of HBeAg, HBeAg/HbeAb serological conversion rate, creatine kinase (CK) before and after treatment, and safety were observed. Results After treatment, biochemical response, virological response and HBeAg serological response was more significant in the treatment group than that in the control group (P<0.05). The percetage of patients with elevated CK in the treatment group was significantly lower than that in the control group (32.5% vs 60%, P<0.05). Conclusion Meteorism tablets combined with telbivudine has attenuated and synergistic effect in treating HBeAg-positive chronic hepatitis B patients.

Objective To describe clinical features,polysomnographic (PSG) alterations and characteristics of motor and distribution during rapid eye movement (REM) sleep in narcoleptic patients with REM sleep behavior disorder (RBD).Methods We retrospectively summarized general features of 22 narcoleptic patients with RBD,96 narcoleptic patients without RBD and 21 healthy subjects as controls.We compared their PSG and the related indexes in 3 groups.Then we analyzed a full-night video-PSG recording in a continuous series in 22 narcoleptic patients with RBD to identify their motor behavior and distribution features.Results There was no significant difference in PSG parameter and correlation index between the narcoleptic patients with RBD group and without RBD group.However,compared with normal control group (20.15 ± 4.52),narcoleptic patients with or without RBD (24.07 ± 5.44,23.40 ± 4.50) showed increased the body mass index(F =4.869,P =0.009),shortened NREM sleep and REM sleep (min) latency at night (4.41 ±7.01,3.55 ±3.98 and 14.69 ±9.62,x2 =31.697,P =0.000;69.39 ±81.39,71.04 ±74.45and 115.31 ± 45.13,x2 =11.485,P =0.003),increased percentage of sleep stage 1,decreased percentage of slow wave sleep,delayed the arousal time and increased number of arousal episode longer than 5 minutes.In narcoleptic patients with RBD,RBD episodes occurred frequentlyatany stage of REM sleep through whole night and the frequency of vocalizations did not significantly differ between the two halves of the night.Pantomimes were significantly more frequent in RBD episodes of the second half of the night.Conclusions The prevalence of RBD is high in narcoleptic patients.Sleep architecture doesn' t differ between narcoleptic patients with and without RBD.There is no correlation between the occurrence of RBD and narcoleptic duration.In narcoleptic patients with RBD,vocalizations and pantomimes accounted formajor proportion of RBD episodes while aggressive-violent movements are rare.
