Objective To discuss the clinical effect of normal saline flushing and heparinized saline flushing in invasive arterial blood pressure monitoring in the critical patients. Methods A total of 140 critical patients were randomly divided into the experimental group and the control group with 70 cases in each group according to the envelope method. The experimental group used normal saline for tube flushing, the control group used heparinized saline (5 U/ml) for tube flushing. The incidence of complications and coagulation index were compared between two groups. Results There was no statistically difference in the incidence of the catheter jam and local infection (P>0.05). The incidence of bleeding events was 14.3% (10/70) in the control group, which was higher than 2.9% (2/70) of the experimental group. The difference was statistically significant(χ2=4.466, P<0.05). The activated partial thromboplastin time, prothrombin time of the control group were (32.22 ± 4.22) s, (11.56 ± 2.12) s, which were longer than (29.84 ± 3.64) s, (10.66 ± 1.48) s of the experimental group. And international normalized ratio of the control group was 1.12±0.14, which was higher than 1.03±0.20 of the experimental group. The difference was statistically significant (t values were-3.573,-2.912,-3.084, P <0.05). Conclusions The normal saline flushing liquid was more safer and reliable in the invasive arterial blood pressure monitoring.

A sectional survey with histochemical technique was carried out on Culex tritae-niorhynchus larvae infected with Coelomomyces indica in comparison to the noninfected larvae. Studies were pursued by using micrograph and imaging analysis. The results showed that the glycogen, protein and nucleic acid (RNA and DNA)reaction in the infected group were less than those of the control group. The gray level assessment in tissue imaging showed marked difference between the two groups. It is suggested that C. indica has significant effect on the above biochemical elements of the mosquito larvae, which might be considered an important mechanism in the pathogenicity of the fungus.

OBJECTIVE: To evaluate the effect of intervention measures on perioperative preventative application of antibiotics. METHODS: 120 surgery patients in our hospital were collected and studied comparatively before (Jul.～Dec. of 2006) and after carrying out intervention measures (Jul.～Dec. of 2008). RESULTS: The rational utilization rate of antibiotic during perioperative period increased from 0% (before intervention) to 56.7 % (after intervention). Average admission day and average medication duration after operation both were shortened (P

ObjectiveTo evaluate bacteria contamination during collection,processing and storage of cord blood to gain insight into contamination mechanism and direct prevention.MethodsFresh cord blood was separated by hydroxyethyl starch (HES) to harvest nucleated cells.The bacteria contamination was tested by culturing 10 ml plasma-red cells with BacT/ALERT 3D-480 automatic blood culture system.Total 87 positive samples were further identified for bacteria species.Ninety six cord blood nucleated cells concentrate with bacteria positive stored in liquid nitrogen(LN2) for 6-7 years were thawed at 37 C and re-cultured for bacteria analysis.ResultsWe collected 19 062 umbilical cord blood.Among them,336 was bacteria positive ( contamination rate 1.8 ％ ).Eighty-seven positive samples were further investigated with facultative bacteria 58 (66.7 ％ ),aerobic 38(43.7％ ) and anaerobic 17( 19.5％ ),Gram- negative accounted for 68％ while positive 32％.The most frequent bacteria were Escherichia coli ( 25.3％ ),Streptacoccus intermediate ( 14.9％ ) and Chromobacteria violaceum(9.2％ ).Ninety-six nucleated cells concentrate with bacteria positive were cryopreserved at liquid nitrogen for researching.Of them,83 samples( 86％ ) showed positive of bacteria culture after deep-low temperature storage for 6-7 years.ConclusionsBacteria contamination rate of the cord blood collection,processing and storage in 2000 ～ 2007 was 1.8％.Stored in liquid nitrogen for 6-7 years,the viability of bacteria was 86％.The aseptic procedures of cord blood collection in delivery room should be intensified.The bacteria re-culture following thawing of cord blood cells is necessary before clinical transfusion.

Objective To investigate the reliability of using inhibitors including Phenylboronic acid (PBA)and Fqucloxacillin(FCC)in detecting derepressed hyperproduction and plasmid-mediated AmpC B-lactamases.Methods PBA and FCC were chosen as inhibitors and double-disk potentiation method and double-disk synergy method were used to detect positive and negative control strains of AmpC β-lactamases and 107 clinical isolates for AmpC β-lactamases production.The positive control strains included E.cloacae (029M),plasmid-mediated ACT-1 type of E.coli DH5a2919,MOX-1 type of k pheumoniae,LAT-2 type of E.coil.The negative control strains included E.cloacae 029(wild-type),E.coli SHV-1,E.coli SHV-2, E.coil SHV-5,E.coli TEM-1,E.coli TEM-3,k peumoniae SHV-18 and E.coli ATCC25922.We compared the results above with the three dimensional test(3-DT)to observe the accuracy in detecting AmpC-BLA.Results 3-DT together with PBA and FCC based inhibition tests showed the 4 positive control strains and the 9 negative control strains were determined as expected.AmpC-BILA was detected in 107 clinical isolates ofEnterobacteriaceaes.The positive rate of3-DTmethod is24.3%.The positive rates ofPBA.FCC double-disk potentiation method and double-disk synergy method are 30.8%(33/107),26.2%(28/107) and 23.4%(25/107),respectively.The conjugate results in two strains of P mirabilis and one strain of K.peumoniae were positive.They were all plasmid-mediated AmpC-Bi.A.There Was a higher false positive when using PBA and FCC-based double-disk potentiation method to detect the induction type of AmpC-BLA, but the accuracy of double-disk synergy method was high.Compared with the 3-DT,the coincidence rate using PBA and FCC-based double-disk synergy method is 99.1%.Conclusions Using PBA and FCC as inhibitors in the double-disk synergy test is a accurate and reliable method to detect AmpC-BLA regardless of derepressed hyperproduction type or plasmid-mediated type.

Objective To explore the value of MRI in detecting the corpus callosum agenesis suspected by US.Methods 19 women with complicated pregnancies,aged from 20 to 37 years(average 28 years) and with gestation from 20 to 38weeks(average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 hours after ultrasound examinations and suspected with fetal corpus callosum agenesis.T2WI and T1WI were performed using HASTE and FLASH,respectively.The features of MRI and ultrasound were compared with that of autopsy or follow-up outcome.Results Of the 19 fetus,14 cases with fetal corpus callosum,3 cases with mild enlargement of lateral cerebral ventricle and 2 cases with leukodystrophy were confirmed by MRI.Of them,accompained with Dandy-Walker syndrome in one and lipoma of corpus callosum in one.One case of Dandy-Walker syndrome and microcephalus respectively missed by US was detected by MRI.Conclusion MRI is superior in displaying fetal corpus callosum agenesis than ultrasound,which is helpful in conforming the diagnosis of fetal corpus callosum,classification and additional cerebral anomalies.

Objective: To understand the current situation and impacts of household factors on of unhealthy dietary habits among preschool children, and to provide reference for preventing the occurrence of unhealthy dietary habits of preschool children. Methods: By using stratified random cluster sampling method, the study selected 1 070 children aged 3-6 years in 7 kindergartens in Urumqi. Household general information , children’s dietary behavior and parenting environment was collected through parent questionnaire survey. Results: The prevalence rate of unhealthy dietary habits among preschool children was 32.71%. Multifactor Logistic regression analysis showed that the unhealthy dietary habits of preschool children were negatively correlated to the following factors, including age of children [β=-0.32, 95%CI=(0.62,0.86)] , gender[β=-0.33,95%CI=(0.53,0.97)], educational level of mothers [β=0.94, 95%CI=(1.79,3.68)] , type of fanmily [β=0.64, 95%CI=(1.414,2.522)] and the scores of social adaptation/selfcare and environmental atmosphere in the family nurturing environment [β=-0.07, 95%CI=(0.90,0.97); β=-0.21, 95%CI=(0.76,0.87)]. Conclusion The cultivation of the dietary habits should pay more attention on younger children and boys, and the enhancement of health education on the children’s eating behaviors among mothers with lower education background and the primary child caregivers in the stem family. Family nurturing environment should be actively improved, in order to prevent the occurrence of children’s unhealthy dietary habits.

Objective: To understand the status quo and influencing factors of overweight and obesity in preschool children, and to provide scientific theoretical reference for the prevention and control of overweight and obesity in preschool children in Urumqi. Methods: Stratified cluster sampling method was adopted to select 1 897 preschool children from 10 kindergartens in Urumqi from October to December in 2021 to understand the status quo of overweight and obesity of preschool children by measuring their height and weight. The influencing factors were collected by questionnaire survey, including Chinese preschoolers eating behavior questionnaire, Chinese preschooler s caregivers feeding behavior scale, 3-6 year old children s home nurture environment scale, and characteristics and influencing factors of physical activity among preschool children. Results: The prevalence of overweight and obesity in preschool children was 31.21% (592), including 19.50% (370) overweight and 11.70% (222) obesity.Childhood overweight and obesity detection rates varied significantly by age, sex, child dietary habits, father BMI, maternal BMI, and maternal pre pregnancy BMI ( χ 2=19.63,28.75,9.45,18.21,18.45,19.36, P <0.05). Multivariate Logistic regression analysis showed that gender, children s eating habits, paternal BMI, pregnancy BMI, satiety responsiveness, external eating, initiative eating, weight concerns, behavior restricted feeding, physical activity and family physical activity environment were the influencing factors of overweight and obesity in preschool children( OR =0.52,1.43,1.51,1.44,0.69,0.74,1.35,1.71,0.81,0.96,1.10, P < 0.05 ). Conclusion Overweight and obesity in preschool children are popular in Urumqi. Education, diet control and scientific exercise should be strengthened to prevent childhood overweight and obesity.
