ObjectiveTo compare the effects of two methods for the treatment of delayed defecation of neonatal meconium. Methods Sixty-seven neonates with delayed defecation of neonatal meconium were divided into experiment group (n=37) and control group (n=30). The former group was managed with abdominal massage followed by glycerol enema and the latter with abdominal massage followed by anus stimulation.Then the groups were compared in terms of the time for initial defecation of meconium,the volume of defecation,exhanstion time for defecation,abdominal distention and vomiting and serum bilirubin within 7 days.Result The treatment group was superior to the control one in terms of time for initial defecation of meconium,the volume of defecation, exhanstion time for defecation (P<0.05) and the incidences of abdominal distention,vomiting and serum bilirubin within 7 days were significantly lower than the control group (P<0.05).Conclusions The method of glycerol enema combined with abdominal massage is more effective for promoting defecation of neonatal meconium than the method of anus stimulation.It can reduce the incidence of abdominal distension,vomiting and pathological jaundice.

Objective:To analyze the accuracy of the digital imaging fiber optic transillumination (DIFOTI) on diagnosis of caries lesions depth using DIAGNOcam system.Methods:This experiment adopted self-matching design.Seventy-four extracted teeth (molar:sixty-six,premolar:eight) with one caries lesions in proximity which were not damaged in surface marginal ridge were selected.Dental calculus and dental stains were removed from the extracted teeth for standby application.A sign was marked in the middle of the occlusal surface edge at the side of decay.Then the teeth were fixed in the standard model of dentition and cavities were adjacent with the sound tooth surface.Sticky wax was applied to seal the level of 2 mm beyond cemento-enamel junction (CEJ) in the direction of occlusion and interproximal space to imitate gingival margin and gingival papilla.The standard models of dentition was seated in imitation head mold.The lesions depth degree was looked into and checked with DIAGNOcam system.Besides,the pictures on the occlusal surfaces were recorded and saved.The sign above could be seen on the picture.The measuring tool in DIAGNOcam system was used to measure the depth of the caries from the sign (as starting point) to the deepest point of caries in the pictures and its length was recorded for a.The line a was lengthened to the contralateral edge of occlusal surface in the photo and the length was recorded for b.A line from the marked point on the occlusal surface edge of the extracted teeth was draw parallel to the line b on the corresponding photo and its length was recorded for c.The depth of the cavities on the projected images was recorded for d,and calculated d/a =c/b (digital optical fiber measured decay depth/caries damage depth of the image =actual tooth width/tooth width of the image),and d =c/b × a inferred.At last,the teeth were taken out from the standard model dentition.The decay of the tooth was removed completely.The actual depth of the cavity was recorded for D.The difference between d and D was recorded for Δd.The software of SPSS 20.0 was used to test the consistency of the results,and the MedCalc 14.8.1.0 software was used for Bland-Altman analysis.Results:The intraclass correlation coefficient (ICC) between d and D was 0.951 (ICC ＞ 75 ％),P =0.263.There was a function relationship y =0.23 ± 0.9 1x between d (x) and D (y).Bland-Altman analysis method showed that the mean of Δd (Δd) was 0.05 mm,the standard deviation of Δd (ΔdsD) =0.308,and the 95％ confidence interval was (-0.55 to 0.65).The amplitude of difference was clinically acceptable.So the consistency of the two measurement modes was high.Conclusion:There was no significant difference between the depth of caries lesions checked with DIAGNOcam system and the depth of the actual cavity,and the consistency was very good.The vitro study suggests that the DIAGNOcam system may be used to assess the depth of caries cavity as a useful tool in diagnosis and treatment.

The nutritional survey was made in 184 anorexia children aged 3-7, 123 of them were treated with various measures for three months. The results indicated that the children with anorexia had low intake and deficiency in energy, protein, minerals and vitamins. Most of them had zinc deficiency, but they simultaneously had two to three nutrients deficiency.The zinc treatment could improve most patient's syndrome and nutritional status. The effect of zinc treatment with vitamines and iron preparations was better than zinc treatment only. The effect of treatment with Chinese medicine also was able to cure the children with anorexia to certain extent.

Objective To investigate whether arsenic trioxide(As2O3)with different density is capable of affecting the invasiveness of neuroblastoma(NB)cells,and to give grounds for NB therapy with As2O3.Methods 1.Well-developed NB cells were selected and exposed to 0.75 ?mol/L,1.50 ?mol/L,3.0 ?mol/L As2O3 for 24 h;2.Collect the adherence cells,count the number and float them in nutrient medium again,add them into the transwell polycarbonate membrane plate that was covered by matrigel,there were 2?104 NB cells in each well;3.After 24 h,take off the membrane,fix the cells which cross the membrane with mehanol and dye them with hematoxylin;4.Observe the NB cells and count them,so the capability of invasion of LA-N-5 was evaluated by transwell chamber assay.Results After 24 h with the different density As2O3,the number of invading LA-N-5 cells was significantly lower in As2O3 group than that in control group(the number of invading cells of the As2O3 group was 28.0?4.0,19.33?4.16,6.33?1.53,respectively,the cell number of the control group was 46.33?6.11)(P=0.013,0.003,0);among the experiment groups,there was no difference between 0.75 ?mol/L and 1.50 ?mol/L(P=0.06),and it was significantly different between 0.75 ?mol/L and 3.0 ?mol/L,1.50 ?mol/L and 3.0 ?mol/L(P=0,0.007),the number of invading LA-N-5 cells of 3.0 ?mol/L As2O3 was the least.Conclusions As2O3 could inhibit the invasive potential of NB cells;the inhibitory action of 3.0 ?mol/L As2O3 is the most.

Objective To study the relationship between renal morphology and renal function,and to assess the value of CT as a criterion to grade renal function.Methods Enhancement CT were performed in 89 patients with no local renal disease whose split renal glomerular filtration rates(GFR)were measured by renal dynamic imaging with ~(99)Tc~m-DTPA.The 178 kidneys were divided into normal renal function,mild and severe renal impairment groups according to renal function.Differences between three groups respect to the mean thickness of renal cortex and parenchyma were assessed by ANOVA.Using Pearson's correlation test,the correlation between the renal cortex,parenchyma thicknesses and renal GFR were examined.The value of CT in predicting renal function was assessed by using ROC analysis.Results The renal cortex thicknesses of normal renal function,mild and severe renal impairment groups were(5.9?1.1),(4.6? 1.1),and(3.3?1.0)mm respectively,and the renal parenchyma thicknesses were(26.3?4.2), (21.3?4.6),(16.2?4.6)mm.There were significant differences of renal cortex,parenchyma thicknesses between 3 groups(cortex F=54.78,P

To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.
