Objective To observe the effect of relative humidity on indoor concentrations of formaldehyde and ammonia. Methods 12 currently decorated rooms were randomly divided into 3 groups, 4 rooms involved in each, in which the average relative humidity of rooms were 55%,65% and 75% respectively. The concentrations of formaldehyde, ammonia were monitored every two days for 9 consecutive days according to GB/T18204.26 -2000 and GB/T18204.25-2000. Results The concentrations of formaldehyde and ammonia decreased gradually with the prolongation of the experimental period. The concentrations of formaldehyde in the rooms of 55%,65% and 75% relative humidity groups decreased significantly after the 5th, 3rd, 3rd day of the experiment compared with those in the same group at the 1st day of the experiment respectively(P

As to a nitrite-oxidizing bacterium screened in our laborator y, the effect of pH, nitrogen sources, carbon sources and sodium chloride on its g rowth was studied in order to obtain high cell density. It showed that the cult ure conditions of nitrite- oxidizing bacterium were 4500mg/L sodium nitrite, 1 .5g/L sodium carbonate, 0~0.5% sodium chloride and 0~0.1% glucose at 28℃~30 ℃, 110 r/min and pH 8.0~8.5. After cultivation for 9 days, the bacteria conc entration reached 4.6?109 MPN/mL and all NO-_2-N in the medium w as converted to NO-_3-N. But the transformation of nitrogen sources was inhibited while the sodium chloride concentration exceeded 0.5% or glucose con centration exceeded 0.1%. According to the test of NO-_2-N conversion with nitrite-oxidizing bacteria in a freshwater aquaculture pond, NO-_2 -N began to decrease on the third day of the moculation of this bacterium and t he concentration dropped from 1.47mol/L to 0.49mol/L after 18 days at 25℃ and pH 8.6.

OBJECTIVETo compare the efficacy differences between dog-days medicinal vesiculation and regular-day medicinal vesiculation for perennial allergic rhinitis (PAR), and observe their effects on serum immune globulin E (IgE) and interleukin-4 (IL-4).

METHODSSeventy-two patients were randomly divided into a dog-days moxibustion group (34 cases) and a regular-day moxibustion group (38 cases). In the dog-days moxibustion group, medicinal vesiculation was applied on the 1st dog-day, 2nd dog-day and last dog-day in summer by lunar calendar, 3 treatments per dog-day for totally 9 times. In the regular-day moxibustion group, the moxibustion was given on the regular day for continuous 9 times. The symptom score, rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of IgE and IL-4 were compared before and after treatment in two groups; the short-term and two-year efficacy evaluation were performed too.

RESULTSThe short-term total effective rate was 88.2% (30/34) in the dog-days moxibustion group, which was not significantly different to 86.8% (33/38) in the regular-day moxibustion group (P>0.05). The long-term total effective rate was 97.1% (33/34) in the dog-days moxibustion group, which was significantly superior to 81.6% (31/38) in the regular-day moxibustion group (P<0.05). After treatment, the serum IgE, IL-4 and RQLQ were significantly reduced (all P<0.01), but the difference between two groups was not significant (all P>0.05).

CONCLUSIONMedicinal moxibustion could be taken as a regular treatment for PAR, which could be performed during the whole year, and dog-days moxibustion could be considered as an enhanced method for prevention and treatment of PAR.

Objective To investigate the correlation between Bispectral index (BIS) value and the prognosis of patients with coma in ICU.Methods A total of 208 patients with coma in ICU were divided into 4 groups according to the BIS value.In group I,BIS value was 0 to 20; groupⅡ,BIS value 21 to 40; group Ⅲ,BIS value 41 to 60; and group Ⅳ,BIS value greater than 60.Comparison of the difference in BIS value with the differences in prognosis of patients with coma was carried out between four groups,and the prognosis of patients with coma was stratified into consciousness,coma,vegetative state,and brain death.Subsequently,the best cutoff score of BIS value calculated for determining the correlation between BIS and mental state was proposed.Results There are no significant differences in the age and APACHE Ⅱ scores between four groups (P ＞ 0.05).It was inverse correlation between BIS value and mental state (r =-0.749,P =0.00).According to the ROC curve,as BIS value was greater than 42.5,there were higher sensitivity and specificity in Conscious-Coma patients.Conclusions BIS value is correlated with the prognosis of patients with coma in ICU,and BIS value can be a useful marker for estimating the prognosis of comatose patients.

Objective To study the feasibility of the acute gastrointestinal injury (AGI) classification standard for evaluation of gastrointestinal function in intensive care unit (ICU) patients,and to discuss its value in administration of early enteral nutrition (EN).Methods A perspective study was conducted.85 patients with AGI admitted to ICU of Tianjin First Center Hospital from January 2013 to June 2013 were enrolled.EN was conducted after ICU admission or within 12-24 hours after high catabolic state.The patients were divided into four groups according to the AGI classification,i.e.grade Ⅰ,Ⅱ,Ⅲ,and Ⅳ,and they were treated according to the treatment procedure for AGI.The primary end points were 7-day rate of intake of standard EN,the degree of disease and nutrition,and their correlation with AGI classification.Secondary endpoint was rate of giving EN within 48 hours.Results Gastrointestinal dysfunction patients accounted for 49.42％ (85/172) of the ICU patients,and number of patients in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ were 29,28,19,9 respectively.On the first day of ICU stay,there were no statistical differences in age,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,serum albumin (ALB) and prealbumin (PA) among four groups,and it was demonstrated that the baseline data were comparable.APACHE Ⅱ score on the seventh day of ICU stay was significantly lower than that on the first day in grade Ⅰ,Ⅱ and Ⅲ patients (grade Ⅰ:20.48 ± 2.45 vs.22.59 ± 2.06,t=-3.120,P=0.031 ; grade Ⅱ:19.34 ± 1.80 vs.21.65 ± 2.22,t=-4.316,P=0.012; grade Ⅲ:20.63 ± 1.34 vs.23.31 ± 1.70,t=-5.640,P=0.000),and serum PA (g/L) was significantly increased (grade Ⅰ:24.37 ± 6.54 vs.10.62 ± 7.24,t=-4.866,P=0.000; grade Ⅱ:19.79± 12.48 vs.11.57±8.94,t=-2.116,P=0.031; grade Ⅲ:19.15±8.43 vs.13.78 ± 6.59,t=-3.601,P=0.000).On the seventh day ofICU stay,the APACHE Ⅱ score was higher in grade Ⅳ than that in grade Ⅰ,Ⅱ and Ⅲ patients (22.87 ± 3.31 vs.20.48 ± 2.45,19.34 ± 1.80,20.63 ± 1.34,P＜0.05 or P＜0.01),and PA was obviously lower in grade Ⅳ than that in grade Ⅰ,Ⅱ and Ⅲ patients (g/L:14.02 ± 8.70 vs.24.37 ± 6.54,19.79 ±12.48,19.15 ± 8.43,P＜0.05 or P＜0.01).There was no statistically significant difference among four groups in respect of serum ALB (F=0.454,P=0.722).The rate of giving EN in 24 hours in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ patients was 95.4％,72.1％,52.0％ and 0,respectively (x2=8.310,P=0.016),and in 48 hours it was 100.0％,83.0％,76.0％,and 0 (x2=5.470,P=0.025).7-day standard EN intake rate was 100.0％,88.7％,84.0％ and 34.0％ respectively in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ patients (x2 =0.720,P=0.017).Correlation analysis showed that there was a negative correlation between AGI classification and rate of giving EN in 1 day (r=-0.62,P=0.04) and 7-day standard EN intake rate (r=-0.76,P=0.02).Conclusions AGI classification can be used to estimate the gastrointestinal function of patients with critical illness,and it has a significant correlation with early EN support.An early goal achieving intervention based on the AGI classification can improve the nutritional status and the general state of the patients.

Objective To investigate the changes of cerebral regional glucose metabolism and regional homogeneity (ReHo) and their relation in patients with major depression disorder (MDD) using 18F-FDG PET/CT and functional MRI (fMRI).Methods A total of 18 MDD patients (6 males,12 females,age:(33.00±7.59) years) and 17 healthy controls (6 males,11 females,age:(34.59±8.96) years) underwent 18F-FDG PET/CT and fMRI.The changes of glucose metabolism on PET and ReHo on fMRI were analyzed individually by SPM and ReHo fMRI 1.0 software.Pearson correlation analysis was used.Results Compared with the glucose metabolism of control subjects,those of MDD patients decreased in the bilateral superior,middle and inferior frontal gyri,bilateral superior and middle temporal gyri,bilateral anterior cingulate cortices,bilateral putamina and caudate nuclei and the left pallidum.Meanwhile the glucose metabolism increased in the bilateral hippocampi and the left thalamus.The ReHo in MDD patients decreased in bilateral superior and middle frontal gyri,left pallidum,bilateral putamina,left anterior cingulate cortex,whereas increased ReHo was found in right hippocampus and right thalamus.The SUV of bilateral superior,middle and inferior frontal gyri,bilateral superior and middle temporal gyri,bilateral putamina,left caudate,left pallidum,left anterior cingulate cortex,bilateral hippocampi and bilateral thalami were correlated with ReHo (r =0.51-0.83,all P＜0.05).However,no correlation was found between the SUV and ReHo in right caudate and anterior cingulate cortex (r=0.41,0.37; both P＞0.05).Conclusion There may be relative characteristic models of abnormal cerebral metabolism and cerebral dysfunction impairment in MDD patients,and the changes of cerebral regional glucose metabolism may be correlated with the changes of ReHo.

An indexing system is constructed,based on the implementation of prevention and control technology for chronic non-communicable diseases in community health service institutions,using both literature review and Delphi method,and using the Analytic Hierarchy Process (AHP) to calculate the weight of the indexing system.The system comprises three level-1 indexes,8 level-2 indexes and 33 level-3 indexes.The research proposed a transition from emphasis of therapeutic means to prevention,and emphasis on prevention and control technologies to the high-risk population in the prevention and control technology of chronic non-communicable diseases,along with development of techniques and measures to encourage behavioral changes of the population with chronic diseases.
