a greater impact,which could account for some pathophysiological changes caused by catch-up growth.

Objective To establish a novel PCR method that can differentiate the two biotype of Mycoplasma urealytium rapidly based on the disparities of parC gene sequences for clinical routine examination.Methods Design two pairs of specific primers and probes for the targeted gene according to the differences of the parC gene sequences from 14 standard serotypes.The specificity of this amplification was verified by detecting two Mycoplasma urealyticum standard strains including serovar1 and serovar4,50 clinical isolated strains ( 12 are Uu strains and 38 are Up strains) and 7 common bacterias from vagina.Collected 70 swab specimens from patients of Sexually Transmit Department with urogenital inflammation symptom and 71 swab specimens from the gynecology health examination population.All those specimens were detected by culture and our method respectively.The sensitivity of this method was evaluated by comparing with the culture.Differences of the infection rate and distribution of biotypes between different populations were analyzed using statistical software.Results Standard strains of Mycoplasma urealyticum and clinical isolates can be typed into two species by the PCR method without nonspecific amplification.The sensitivity of PCR method is much higher than that of culture ( P＜0.05).The infection rates of Uu,Up and the mixing were 8.57％,61.40％,24.30％ respectively for the patients with vaginitis.However,it was 8.80％,67.60％,8.45％ respectively for the gynecology health examination population.There is a significant difference of the total infection rate between the two population(P＜0.05).It showed no significant difference with the distribution of the two types of simple infection in the two groups ( P＞0.05).But the rate of mixing infection is much higher in the patients with vaginitis ( P＜0.05 ).Conclusion The pathology of Mycoplasma urealyticum may be related to the mixed infection of different biotypes.

AIM: To explore the influence of processing with fresh-scorpion on element contents in crude scorpion in order to elucidate the processing method. METHODS: Macro-elements Ca,Mg and trace-elements Fe,Cu,Zn and Pb in crude scorpion were determined with emission spectrometric method. RESULTS: Contents of Ca,Mg in live-scorpion group were obviously lower than that in commercial-scorpion(P0.05). CONCLUSION: Processing with live-scorpion has obviously advantage over one with commercial scorpion on element contents.

Objective:To investigate the preventive effect of tetramethylpyrazine (TMP) on hypoxic pulmonary hypertension in rats and the underlying mechanism.Methods:Thirty-six male Sprague-Dawley rats were randomly divided into three groups:the normal control group,hypobaric and hypoxic group and TMP group (100 mg·kg-1·d-1).After the animal models of hypobaric and hypoxic pulmonary hypertension were established,mean pulmonary artery pressure (mPAP),mean carotid artery pressure (mCAP),ratio of right ventricular/(lift ventricular + interventricular septum) (RVHI) and morphological changes of pulmonary vessels were observed and the rates of wall thickness/external diameter (WT%) and wall area/total vascular area (WA%) were calculated.The contents of nitric oxide (NO),endothelin-1 (ET-1),hypoxic-inducible factor-1 (HIF-1) and vascular endothelial growth factor (VEGF) were detected in serum after the 21-day treatment with TMP.Results:The values of mPAP,RVHI,WT% and WA% of hypobaric and hypoxic group were significant higher than those of the normal control group (P<0.05 or P<0.01),and those of TMP group were obviously lower than those of hypobaric and hypoxic group (P<0.05 or P<0.01).The condition of hypobaric and hypoxic had no significant effect on mCAP,and there were no significant differences among the groups (P>0.05).The values of NO in serum of hypobaric and hypoxic group was lower than those of the normal control group (P<0.05) and those of TMP group were obviously higher than those of hypobaric and hypoxic group (P<0.05).The values of ET-1,HIF-1α and VEGF in serum of hypobaric and hypoxic group were higher than those of the normal control group (P<0.05) and those of TMP group were obviously lower than those of hypobaric and hypoxic group (P<0.05).Conclusion:TMP can effectively prevent pulmonary hypertension induced by hypobaric and hypoxic and structural remodeling of pulmonary arterioles.The mechanism may be related to the content up-regulation of NO and activity down-regulation of ET-1,HIF-1α and VEGF in serum of rats.

Objective To study whether methicillin-resistant Staphylococcus aureus (MRSA)will increase the burden of patients with hospital-acquired pneumonia (HAP).Methods Patients with Staphylococcus aureus HAP in a hospital between January 1 ,2013 and November 31 ,2014 were selected,patients with MRSA HAP were as case group,patients with methicillin-sensitive Staphylococcus aureus (MSSA)HAP were as control group,propen-sity score matching (PSM)analysis were conducted to compare the prognosis of MRSA HAP and MSSA HAP (length of hospital stay, duration from infection to discharge, mortality, total therapeutic cost ). Results APACHE II score in case group was higher than control group before PSM was conducted,length of hos-pital stay and duration from infection to discharge were both longer than control group (40[20,94]d vs 28[21 ,53] d;19[10,46]d vs 17[8,29]d,respectively,both P <0.05).APACHE II score in case group and control group af-ter conducting PSM was not significantly different(P >0.05 ),data were balanced and comparable;there were no significant difference in length of hospital stay between two groups (28[21 ,52]d vs 28[21 ,53]d),duration from in-fection to discharge (15[9,25]d vs17[8,29]d),mortality(10.87% vs 15.22%),and total therapeutic cost (121 013.5[80 747.21 ,176 200]yuan vs 119 911 .2[66 994.08,241 184.7]yuan)(all P >0.05).Conclusion APACHE II score is an important factor affecting prognosis;after balancing this factor,there is no difference in the prognosis of patients with MRSA and MSSA HAP,MRSA HAP can not increase the burden of disease.

Objective To investigate the contamination of clinically used tablet computers,and compare the effec-tiveness of three cleaning and disinfection methods.Methods The front and back surfaces of tablet computers were wiped and detected by handheld adenosine triphosphate (ATP)fluorescence detector,the study was divided into baseline stage and cleaning and disinfection stage.During baseline stage,the tablet computers in use were directly wiped,during cleaning and disinfection stage,the tablet computers were wiped by normal saline-moistened gauze, alcohol-moistened gauze,and wet napkin.Results During baseline stage:20 tablet computers were wiped,the qualified rate was 0,the median of relative light unit (RLU)of ATP detection was 218.00.During cleaning and dis-infection stage,10 tablet computers were wiped in each cleaning and disinfection group,and the qualified rate of normal saline-moistened gauze,alcohol-moistened gauze,and wet napkin groups were 50.00%,0,and 60.00% re-spectively,the median RLU of ATP detection were 28.50,79.00,and 29.00 respectively.Except comparison be-tween saline-moistened gauze and wet napkin groups (P =0.97),multiple comparison of RLU of ATP detection amongthe other groups were significantly different (all P <0.001 ).Conclusion Contamination of medical tablet computers are serious,wet napkin wiping is an ideal method for cleaning and disinfection,but the frequency for cleaning and disinfection needs to be further studied.
