Objective To investigate whether two polymorphism sites of the the exon 2 Lys65Lys(G/A) and exon 9 Va1365Met(G/A) in T ceils immunoglobulin domain and mucin domain protein-4(TIM-4) are associated with asthma in Chinese Han population of Hubei province. Methods The polymorphisms were de-tected with polymerase ehain reaction-restriction fragment length polymorphism(PCR-RFLP) in 185 cases of al-lergic asthma and 162 healthy controls. The genotype and allele frequencies were calculated and analyzed. Re-sults(1)The genotype frequencies of G/G, G/A and A/A in Lys65Lys(G/A)polymorphism were 0.840, 0.160 and 0 respectively in the healthy population, and were 0.859, 0.141 and 0 respectively in the allergic asthma population. No significant difference in genotype and allele frequencies was found between asthma pa-tients and the control subjects (P=0.603, P=0.618). (2) The polymorphism of the Val365 Met(G/A) was not detected in our study. Conclusion There is polymorphism site of the exon 2 Lys65Lys(G/A)in TIM-4, but this polymorphism site is not associated with asthma in Han nationality in Hubei Chinese population. There is no SNP of the exon 9 Val365Met(G/A) in TIM-4 in Chinese Han population of Hubei province.

Objective To survey on the condition of critically ill children in emergency room (ER) for improving the care for them.Methods Data of 374 critically ill children in emergency intensive care unit (EICU) were recorded in the respects of mode of sending them to ER,rescue during transport,length of stay in ER,blood gas,electrolytes,accuracy of assessing pediatric critical illness score/neonate critical illness score (PCIS/NCIS) and Glasgow Coma Scale (GCS),correctness of determining SIRS,sepsis and septic shock.Results Of 374 patients,neonates were 29.9％,and the mean age of children patients not including neonate was 37.4 months.The mean length of ER stay was 4.7 hours (0.42-96 hours).Of 374 patients,those with infection diseases were 47.6％,and the main vehicles for transportation of patient sent to ER were Taxi (38.3％),ambulance (28.4％) and private cars (21.5％).Total fatality was 12.3％ and ER fatality ( 15.6％ ) was higher than in - hospital fatality ( 10.3％,P ＜0.01 ).The mean PCIS/NCIS of 374 patients were 81.92 ± 9.66,and the PCIS/NCIS ≤ 90 accounted for 81％.Of assessed GCSs of 172 patients,GCS≤8,GCS 9-12 and GCS 13-15 accounted for 35.5％,21.5％ and 43.0％ respectively,and fatalities were 26.23％,10.81％ and 5.41％ correspondingly (P ＜0.01 ).The PCIS values of GCS≤8 and GCS 9-12 patients were lower than those of GCS 13-15 patients (P ＜ 0.01 ).There was no significant difference in PCIS between GCS≤8 and GCS 9-12 ( P ＞ 0.05 ).PCIS and GCS were positively correlated (r=0.454,P=0.01).Of374 patients,41.7％ had SIRS,and 25.7％ had sepsis.Of 262 children not including neonates,43.5％ had shock,and 61.4％ of these shock children were septic shock.In 374 patients,those with hyponatremia accounted for 37.2％,and those with hyperkaliemia accounted for 22.0％.The rate of hypoglycemia found in neonates was 20.91％ and rate of hyperglycemia occurred in neonates was 29.1％.The rate of hypoglycemia found in children patients was 9％ and hyperglycemia was 66.7％.Patients with pH ＜ 7.35 accounted for 67.8％ and those with pH ＜ 7.2 were 33.1％.Conclusions The majority of children patients in pediatric ER were neonates and infants.The length of ER stay was short with mean value of 4.7 hours (0.42-96 hours).ER fatality was higher than in - hospital fatality,suggesting the critically ill children patients should be admitted as early as possible.The rate of using ambulance was only 28.4％.The Emergency Medical Service (EMS) should be improved to enhance the public sense of the EMS available.PCIS/NCIS can be used in ER for assessing the conditions and prognosis of critically ill children.GCS ≤8 and GCS 8-12 patients accounted for 57％ with majority of nontrauma brain injury.The values of PCIS in GCS≤8 and GCS 9-12 patients were much lower than those in GCS 13-15 patients.Patients with GCS ＜ 13 might be in critical settings.Majority of shock patients were septic shock (61.4％).Hyponatremia,hyperkalemia,hyperglycemia and hypoglycemia often occurred in critically ill pediatric patients and hypoglycemia not excepted in the neonates should have attention paid to.The main factor of acid -base balance disorder in critically ill children was acidosis (67.8％).

Objective The aim of this study was to assess the relationship between the oral health habit and halitosis. It can provide an advisory basis for nurse giving individualized oral health instruction to patients of halitosis and can improve the result of prevention and treatment for halitosis accordingly. Methods 202 patients with periodontal disease were chosen to participate in this study. The study included the questionnaire of oral health habit and the halitosis diagnosis by organoleptic assessment.Comparisons of difference in the knowledge of oral health habit between the subjects with and without halitosis were conducted. Results Brushing times in subjects without halitosis were significantly more than that in subjects with halitosis. Brushing teeth in evening and interproximal brush usage were much better in subjects without halitosis than that in subjects with halitosis,respectively. Conclusions Good oral health habits could decrease the incidence of halitosis.

Objective To discuss the clinical application of simplified neonatal critical illness score (sNCTS)in comparison with original neonatal critical illness score(oNCIS)published in 2001.Method A total of 705 neonates referred to neonate ICU(NICU)from 1 st January 2007 to 31th December 2009 were prospectively studied with control.The patients were scored by oNCIS on admission day,3rd,7th days after admission and on the day of discharge or dead.At the first scoring on admission,2 items of the PaO2 and pH were excluded from oNCIS's 10 items,and the remaining 8 items were used.Three items of plasma sodium,potassium and creatinine or BUN were scored out from 8 items and the still remained 5 items were used for the subsequent 3 scorings.The remaining 8 and 5 items were used as a simplified neonatal critical illness score.The simplified NCIS was evaluated by comparing the patients'condition that was assessed by the originat NCIS.The consistency rate between oNCIS and sNCIS should be over 80%.Results There were 8 items were used to evaluate the severity of disease on admission, and the consistence rate was 86.7%with the original NCIS.The 5 items selected from the original NCIS were used on the 3rd,the 7th days and the day of discharge or death.the consistence rate with original NCIS were 86.6%to 95.7%.A close correlation existed between the original NCIS and simplified NCIS(P<0.01).There were significant differences in mortality rates of the non-serious,serious and extremely serious groups between original NCIS and simplifled NCIS used for the first and the last seorings(P<0.01).Within a cohort of neonates with the same general condition,the assessments of mortality rates were not significantly different between these two methods (P>0.05).Conclusions Compared with the original NCIS.the simplified NCIS is consistent to a large extent in disease assessment,which is a concise way to evaluate the critical ill neonates objectively and can be easily applied to clinical practice.

AIM: To observe whether transfection of mammalian expression vector pEGFP containing the gene of B-cell specific moloney leukemia virus insertion site 1(BMI-1) could express in human cervix cancer cell line HeLa, and to detect its effect on HOX family expression and cell cycle.METHODS: pEGFP-BMI-1 was transfected into HeLa cells with Lipofectamine 2000. The expression of pEGFP-BMI-1 was determined by EGFP fluorescence and Western blotting. SYBR green I real-time RT-PCR was used to quantitate mRNA expression of P16~(INK4a), hTERT, HOXA9, HOXB4 and HOXC13. FACS analysis was used to detect the change of cell cycle.RESULTS: In HeLa cells transfected with pEGFP-BMI-1, the results of real-time RT-PCR showed that the mRNA expressions of P16~(INK4a), HOXA9 and HOXC13 were reduced to 9.2%, 10.9% and 69.7%, respectively, as compared to control HeLa cells (P<0.01). However, hTERT and HOXB4 mRNA expressions did not change significantly (P>0.05). FACS analysis showed a decrease from 65.68 % to 50.53% in G_1 population and a significant increase from 27.17% to 39.59 % in S population after transfection (P<0.01).CONCLUSION: BMI-1 over-expression in HeLa cells down-regulates mRNA expressions of P16~(INK4a), HOXA9 and HOXC13, decreases G_1 population and increases S population. Therefore, BMI-1 may be involved in carcinogenesis and cancer development.

Telomerase activity and the expression of telomerase subunits (for example, telomerase reverse transcriptase and telomerase associated protein 1 and telomerase RNA component) of peripheral white blood cells were detected in the patients with acute myelogenous leukaemia (AML) and the correlation between telomerase activity and the expression of telomerase subunits was observed. In 94 peripheral white blood cells from 18 healthy volunteers and 76 patients with AML, including 31 AML at initial presentation, 24 at relapse and 21 at complete remission, the telomerase activity and telomerase subunits mRNA or RNA were detected by PCR-ELISA and RT-PCR respectively. The results showed that the positive rate of telomerase from patients with AML at initial presentation, at relapse and at complete remission was 74.1%, 79.2% and 4.8% respectively. The positive rate of telomerase reverse transcriptase mRNA from healthy volunteers, AML at initial presentation, AML at relapse and AML at complete remission was 5.6%, 80.6%, 83.3% and 9.5% respectively. The positive rate of telomerase associated protein 1 mRNA and telomerase RNA component in all samples were 100%. It was suggested that the up-regulation of telomerase activity and the expression of telomerase reverse transcriptase is correlated closely with the occurrence and relapse of AML, so telomerase activity and the expression of telomerase reverse transcriptase may be used to estimate the curative effect and predict relapse of AML. Moreover, the up-regulation of telomerase activity is correlated with the expression of telomerase reverse transcriptase significantly.

To detect the expression of telomerase subunits (human telomerase reverse transcriptase, human telomerase associated protein 1 and human telomerase RNA) in gastric cancer and to examine the role that different telomerase subunits play in the gastric carcinogenesis, reverse transcription-polymerase chain reaction (RT-PCR) was used to detect telomerase subunits messenger RNA in 24 samples of gastric cancer and corresponding non-cancerous tissue. The results showed that the positive rate of hTERT mRNA from gastric cancer and corresponding non-cancerous tissues was 100% and 25%, respectively. The former was significantly higher than the latter (chi2 = 26.4, P < 0.01). The positive rate of hTEP1 mRNA from gastric cancer and corresponding non-cancerous tissues was 100% and 91.7%, respectively and no significant difference was found between them (chi2 = 2.1, P > 0.05). The positive rates of hTR for gastric cancer and corresponding non-cancerous tissues were both 100% and no significant difference existed between them. It is concluded that in contrast to hTEP1 and hTR, the up-regulation of hTERT mRNA expression may play a more important role in the development of gastric cancer.

Objective: To develop a magnetic solid-phase extraction combined with gas chromatography-tandem mass spectrometry (GC-MS/MS) based on pyrrole-modified magnetic nanoparticles to determine 16 types of phthalic acid esters (PAEs) in commercial liquors. Methods : Fe3O4 magnetic nuclei were prepared by hydrothermal synthesis, and the polypyrrole-modified magnetic nanomaterials were prepared with the chemical oxidation method. Magnetic solid-phase extraction of beer, grape wine, rice wine and Chinese spirits was performed at 10% alcohol by volume, extraction duration of 20 min and ethyl acetate elution of 10 min, followed by addition of 1 g NaCl for reduction of emulsification effect. The 16 types of PAEs were determined using GC-MS/MS with DB-5MS capillary column (30 m×250 μm, 0.25 μm) under the mode of electron impact ionization (EI) and dynamic multiple reaction monitoring (dMRM), with quantitative analysis using the external standard method. The standard curve, detection limit, spike recovery rate and precision of GC-MS/MS for determination of 16 types of PAEs were evaluated. Results: Pyrrole was successfully embedded onto the surface of magnetic nanoparticles in the form of polymer, and the magnetic nanoparticles modified by polypyrrole were well characterized, showing unapparent matrix and emulsification effects. There was a good linear relationship for the 16 types of PAEs at 50 to 5 000 ng/mL (r=0.999 5-0.999 9), and the spike recovery rate of 16 types of PAEs ranged from 71.61% to 110.50% at 100, 500 and 1 000 μg/kg, with relative standard deviations of 3.78% to 7.41%, detection limits of 0.02 to 1.47 μg/kg. PAEs were detected in 20 out of 50 liquor samples, with 30.00%, 60.00%, 40.00% and 70.00% detection rates in beer, grape wine, rice wine and Chinese spirits, respectively. Conclusions This method is sensitive to determine 16 types of PAEs in liquor samples, with unapparent matrix and emulsification effects, and the polypyrrole-modified magnetic composite nanoparticles present high adsorption of PAEs in liquor samples, which is feasible for monitoring of PAEs in multiple types of liquor samples.
