Objective To study direct economic loss of healthcare-associated infection (HAI)in hospitalized children with acute respiratory infection (ARI),and the influence in satisfaction degree of children’relatives.Methods Clinical data of 1 039 children with ARI in a pediatrics ward between April 1,2012 to March 31,2013 were analyzed retrospective-ly.50 patients with HAI were in case group and 50 patients without HAI were in control group.The difference in medical cost and the degree of satisfaction of children’s relatives were compared between two groups.Results Medical cost of pa-tients in case group was significantly higher than control group([P 25 - P 75 :￥3 095.54 - ￥4 779.48]vs [P 25 -P 75 :￥1 744.14-￥2 382.07],Z =5.89,P <0.01).The expenses in medicine,laboratory examination,diagnosis and treatment,and nursing in case group were all higher than control group,there were significant differences between two groups(all P <0.01 );Hospitalization day of case group was significantly longer than control group ([P 25 -P 75 :9 d-15 d]vs[P 25 -P 75 :6 d-8 d],Z =5.79,P <0.01 ).Satisfaction degree of patients’relatives in case group was significantly lower than control group (Z =8.22,P <0.01).Conclusion HAI occurred in ARI children can increase medical cost,prolong length of hospital stay and decrease satisfaction degree of patients’relatives.

Objective:To study the correlation of β-fibrinogen-854G/A,-455G/A,-249C/T,-148C/T,448G/A and BcI-1G/A polymorphisms, functional expression of plasma fibrinogen concentration, molecular reactivity, and the type of cerebral infarction.Methods: A casecontrol study was used to analyze 54 patients with main-think cerebral infarction(MCI), 106 patients with penetrating-arterial cerebral infarction (PCI)and 160 heathy cases as control group in Kailuan Hospital between July 2002 and June 2003.Gene polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).Fg concentration, fibrin monomer polymerized velocity(FMPV), absorbance maximum(Amax), FMPV/Amax and biochemistry factors including TG were measured, Results: Fg concentration, FMPV, FMPV/Amax in the MCI group and TG, VLDL and FMPV in the PCI group were higher than in the control group(P＜0.05).The frequencies of854A and Bcl-1A alleles had significant difference among three groups,and the frequencies of GA and AA genotypes in the MCI and PCI groups were higher than in the control group(P＜0.05), however, no different genotypes and allele frequencies of the remaining sites were found in the three groups(P＞0.05).Fg concentration and FMPV of allele T carriers in the MCI group were less than that of-249C/C homozygous ones(P ＜0.05); FMPV/Amax of allele T carriers in the PCI group was higher than that of-148C/C homozygous ones(P＜0.05);with allele A carriers, Fg concentration of control group and FMPV of PCI group were higher than that of Bcl-1 wild homozygote(P＜0.05).Conclusion: Bβ-249 C/T polymorphism in the 5-flanking promoter region can influence the expression of plasma FMPV, Bβ-148 locus is the main regulation location of Fg molecular conglomerate function.Bcl-1 locus in the 3-flanking region is an important gene regulator of plasma Fg concentration, moreover,people with its mutated genotypes are susceptible to MCI.The abnormal plasma Fg concentration, FMPV/Amax and FMPV simultaneously are important risk factors for MCI, and only abnormal FMPV and TG are prone to PCI.

Purpose To explore the significance of MR diffusion tensor imaging (DTI) in diagnosing and predicting the motor function of patients with acute ischemic stroke in the brainstem. Materials and Methods Twenty patients with acute ischemic stroke in the brainstem and 20 normal controls were enrolled in the study. DTI was performed on all 40 subjects. Fractional anisotropy (FA) in specific regions were measured including infarction lesions, cerebral peduncle, the posterior limb of the internal capsule in the affected side and corresponding unaffected regions. The number and the length of the corticospinal tracts (CST) of both affected and unaffected sides were also measured. The correlation of FA, the number and the length of the CST, the NIH stroke scale (NIHSS) at the admission, 3 months and 6 months was analyzed. Results The FA values of infarction, cerebral peduncle, and the posterior limb of the internal capsule, and the number of CST in the affected side were significantly less than that of the corresponding unaffected regions (P<0.05). The rFA (<7 d) in the affected cerebral peduncle was negatively correlated with NIHSS and the score of the upper and lower extremity muscle strength at the admission, after 3 months and after 6 months (P<0.05). However, the rFA of the infarction and the posterior limb of the internal capsule, the ratio of the number and the length of CST of affected/unaffected sides had no correlation with NIHSS score and the score of the muscle strength. Conclusion The rFA in the cerebral peduncle is helpful for early evaluation and predicting recovery of the motor function in the patients with acute ischemic stroke in the brainstem.

Objective To explore the effect of radon released from water on the indoor radon activity concentration in groundwater supplies.Methods Two groundwater supplies in a city were chosen.Radon concentrations in three kinds of water samples were determined by using a continuous radon monitor with air-water exchanger,including source water,finished water and tap water.The solid track detector was used to analyze the indoor radon concentration in water supplies.Results The concentrations of radon in source water,finished water and tap water were (7.59 ± 1.36),(3.56 ±0.86),(3.68 ±0.81)Bq/L and (12.19 ±0.57),(7.87 ± 1.12),(9.50 t 1.12) Bq/L,respectively.The concentration of radon was the highest in source water and at less varying level in finished water and tap water.Aeration and filtration tank process significantly decreased radon activity in water.Radon concentrations in aeration and filtration rooms were 4 218 Bq/m3 and 1 937 Bq/m3,respectively,which exceeded the limit in work place (1 000 Bq/m3).Conclusions Aeration and filtration workplaces for groundwater supplies were found to contain elevated radon concentrations in air,which was released from groundwater.Radon issues in groundwater supplies in China should be paid more attention.

BACKGROUND:Preliminary data showed that the application of human platelet lysate to human umbilical cord mesenchymal stem cell culture can better maintain the characteristics of stem cells than the application of serum-free medium. However, the serum-free medium can better improve the proliferation of mesenchymal stem cells in vitro than the human platelet lysate.OBJECTIVE:To screen out a better mesenchymal stem cell cultivation system that can greatly maintain the characteristics and proliferation rate of human umbilical cord mesenchymal stem cells.METHODS:Six human umbilical cord specimens were inoculated in six culture systems, and the primary culture of umbilical cord mesenchymal stem cell was performed. These six culture systems were respectively MesenCult serum-free medium with 2% human platelet lysate (group A), StemPro serum-free medium with 2% human platelet lysate (group B), MesenCult serum-free medium (group C), StemPro serum-free medium (group D), low glucose-DMEM with 10% fetal bovine serum (group E), low glucose-DMEM with 10% human platelet lysate (group F). The cells were subcultured at 14 days after inoculation to compare the effects of different culture systems on the morphology, surface markers, differentiation and proliferation of human umbilical cord mesenchymal stem cells.RESULTS AND CONCLUSION:(1) The morphology of passage 3 cells in group D was elongated and uneven in size. The morphology of passage 3 cells was flattened in groups E and F, but the cells in the other groups were spindle-shaped and uniform. There were no significant changes in morphology and size between passage 3 and 5 cells in A and B. In group C, the morphology of passage 5 cells was more flattened and uneven in size compared with passage 3 cells. In group D, the morphology of passage 5 cells was more elongated than that of passage 3 cell. In group E, the morphology of passage 5 cells was more flattened than that of passage 3 cells. There was no significant difference in morphology between passage 3 and 5 cells in group F. (2) The expression rate of cell surface markers had no significant difference at different passages in each group. (3) The adipoinduction and osteoinduction rates were relatively higher in groups A and B compared with groups E and F, and lowest in groups C and D. (4) The cell proliferation rate for each passages in group A was significantly higher than that in group C. The cell proliferation rate for each passage in group B was significantly higher than that in group D. The cell proliferation rate for each passage in groups E and F was significantly lower than that in groups A and B. To conclude, these results suggest that the combination of serum-free medium with human platelet lysate could better maintain the characteristics and the proliferation efficiency of mesenchymal stem cells.

Objective:To explore the application value of conventional ultrasound(US) in detecting occult bleeding lesions in joints of patients with hemophilia.Methods:Twenty-seven children with severe hemophilia A who received factor Ⅷ prophylactic treatment from March 2017 to April 2018 in Nanfang Hospital, Southern Medical University were enrolled. Clinical data were collected from routine practice accompanied with US examination, hemophilia joint health score (HJHS) 2.1 assessment and the history of hemarthrosis of both ankles, elbows and knees at baseline and at 1 year follow-up.Results:A total of 157 joints of 27 patients were followed up for one year. During the treatments, 74 joints were found without history of hemarthrosis, among which the total US score of 14(14/74, 18.9%) joints increased, and HJHS 2.1 score of 11(11/74, 14.9%) joints developed. There was no significant change in the HJHS 2.1 score of 108 joints, among which 25 joints (25/108, 23.1%) had an increase in the total US score.However, there was no significant change in the total US score for 93 joints, of which 9(9/93, 9.7%) had an increase in HJHS 2.1 score.Conclusions:US examination can sensitively detect hemophilia arthropathy in joints without history of hemarthrosis and without obvious progression of arthropathy by HJHS 2.1 examination, and provide clinicians with more accurate joint information.
