AIM: To compare the difference in serum prolactin levels and the concentrations of anti-infective factors of human colostrums between normal labor and cesarean section. METHODS: The serum prolactin levels were measured at 48 h, 96 h after parturition in 100 cases of normal labor and cesarean using radioimmunoassay. Furthermore, the levels of SIgA, IgG, IgM, C3, C4 were tested in 100 cases at the same time using the technique of immuno-turbidimetry. RESULTS: The serum prolactin levels in normal labor tested at 48 h after parturition were significantly different with that of the cesarean section group. But there was no significant difference in serum prolatin levels 96 h after parturition between the two groups. The levels of SIgA,IgG,IgM,C3 and C4 of the colostrum in the cesarean group were higher significantly than those of the normal group at 48 h after parturition. (P<0.05 or P<0.01). At 96 h after parturition, there was no significant difference in SIgA, IgG, IgM and C3 between the two groups except C4. CONCLUSION: At 48 h after paturition, the serum prolactin levels of normal labor group are higher than that of the cesarean section group. The concentrations of anti-infective factors (SIgA, IgG, IgM, C3 and C4) of human colostrums at 48 h after paturition in cesarean section group are higher than those of normal labor group.

The "Assessment system for spiritual civilization development of service industries in Shanghai" is called into play to guide the survey of patients' satisfaction for service centers in hospital's outpatient clinics. Survey feedback recovered is analyzed with the key driving factors analysis model and the four-quadrant analysis. This practice identified the most critical areas to improve the satisfaction for such centers, providing theoretical references for constant quality improvement in hospitals, new insights for hospital branding, and guidelines for further health reforms.

Objective To study the inhibition of AP-1 transcription factor activity by Hint1 gene over expression in HepG2 cell lines. Methods The Hintl gene was amplified, and then was inserted into the pcDNA3/HA eukaryotic expression plasmid. The constructed pHA-Hint1 plasmid was confirmed by DNA sequencing. The pHA-Hint1 was transfected into the HepG2 human hepatoma cells. Semi-quantitative RT-PCR and Western-blot were used to detecte the expression of HA-Hint1. The HepG2 cells were co-transfected with pHA-Hint1 and pAP-1/Luc luciferase reporter. At 36 h after transfection, luciferase assay system was used to detect the AP-1 transcription factor activity. Results The constructed pHA-Hint1 was confirmed by DNA sequencing, pHA-Hint1 gene transduction through lipofectine induced over-expression in HA-Hint1 mRNA (t =3.89, P<0.05) and HA-Hintl protein (t=3. 12, P<0.05). Co-transfection of Hint1 gene inhibits AP-1 luciferase activity. Cotransfection with increased concentration of a pHA-Hint1 plasmid (0 μg/ml, 0. 5 μg/ml, 1.0 μg/ml, 1.5 μg/ml, 2. 0 μg/ml) produced a concentration-dependent inhibition of AP-1 transcription factor activity. At the concentration of 1.5 μg/ml, and 2.0 μg/ml, the activity inhibition reaches significant difference ( F = 72. 009, P < 0. 05 ). Conclusion Over-expression of Hintl can, at least in part, inhibit the AP-1 transcription factor activity in HepG2 cells.

Objective To analyze the expression of serum anti M phospholipase A2 receptor (PLA2R)antibody in idiopathic membranous nephropathy (IMN),and to investigate its value in the diagnosis and evaluation of idiopathic membranous ne-phropathy.Methods One hundred and eighteen patients with biopsy-proved glomerular diseases were involved in this study, including 97 cases with IMN,21 cases with IgA nephropathy (IgAN)and 19 healthy people.ELISA was used to detect ser-um anti-PLA2R antibodies.Correlations of anti-PLA2R antibody level with laboratory parameters,including serum albumin, 24-hour urine protein of IMN patients were evaluated.Results The median of anti PLA2R antibody in IMN group,IgAN group and healthy group was 45.2(3.6~705.9)RU/ml,5.9(2.3~10.6)RU/ml and 1.2(0.6~9.3)RU/ml.The levels of serum anti PLA2R antibody in IMN group were higher than those in IgA nephropathy group and healthy control group.The difference was statistically significant (t=-5.027,-3.077;P=0.05).Among 97 cases with IMN,76 cases showed posi-tive anti-PLA2R antibodies (positive rate 78.35%).There was none patient showed positive anti-PLA2R antibody respec-tively in IgAN and healthy people.Furthermore,anti-PLA2R antibody level was negatively correlated with serum albumin (r=-0.453,P=0.000)and positively correlated with CREA,TC,ESR,24 hour urine protein (r=0.233,0.234,0.363, 0.586;P=0.004,0.217,0.021,0.000)in IMN patients.Conclusion Serum anti PLA2R antibody may be used as a IMN specific marker for the diagnosis of IMN,and it has important reference value for evaluating the severity of IMN.

9).Renal pathology revealed 3 patients with class Ⅳ, 1 patient with class Ⅱ. Image results showed diffuse pulmonary infiltration lesions. Bronchial lavage fluid was hemorrhage. Three patients recovered after treatment with corticosteroid and intravenous cyclophosphamide therapy. Conclusions Diffuse alveolar hemorrhage is rare serious complications of lupus nephritis. Aggressive immunosuppressive therapy should be started early for a favorable outcome.

Objective To design a new frequency domain magnato-aoustic imaging system to image the conductivity of medium.Methods A continuous sine wave signal was adopted to stimulate the MAT signal. The lock-in technique was applied to measuring the amplitude and phase of the magneto-acoustic signal. The drive control program of the imaging system was designed using virtual instrument tools. The experiments were conducted on the phantom made of coper wire.Results The amplitude precision was improved up to 10-7 Pa, while the system could locate the sonic source with locating precision of millimeter.Conclusion A new magneto-acoustic imaging system is proposed with high locating precision as well as low frequency excitation, which is significative to the study on the sonic source theory and improvement of the imaging precision.

Objective To investigate current status of preschool children's social competence and its relation to tempera-ment type. Methods A total of 1 251 children participated in this study. The questionnaire was conducted and the children were assessed usinginfant-junior middle school student's ability of social life scaleandchildren's temperament scale. Results No significant gender difference was observed in total score of social competence (P>0.05). The total score of live independently was higher in girls as compared to boys (P<0.05). A significant gender difference was observed in classified scores of social competence (P<0.05). Girls with excellent or better-than-normal social competence were more than boys (P<0.05). The distribu-tion of the temperament type in preschool children were the difficult-to-raise type (8.1%), the start-slow type (15.4%), the stan-dard type (69.0%) and the easy-to-raise type (7.5%). There was statistically gender significance (P<0.05) in the distribution of the temperament types. The percentage of difficult-to-raise type was higher in girls than in boys. The percentage of easy-to-raise type was higher in boys than in girls. The total score and classified scores of social competence had significant difference among children with different temperament types (P<0.05). Conclusions There is significant diffe-rence of social competence in chil-dren with different temperament types. Corresponding educational measures according to the child's temperament may be bene-fit to the development in preschool children.

Objective To evaluate the impact of sequence on the quality of bowel preparation in patients with anesthesia for same-day sequential bidirectional endoscopy and propose the optimal procedural sequence.Methods Single center blinded randomized observational study.Sixty-five patients were randomized to either the gastroscopy-first group or the colonoscopy-first group.Bowel cleanliness according to Boston bowel preparation scale (BBPS) scores were evaluated,also done the propofol dosage,caecal intubation time,procedure duration and complications.Results The BBPS score of entire colon showed no difference (6.72 ± 1.34 vs.6.89 ± 1.50,P =0.638),but the BBPS of ileal-cecum portion was higher in the colonoscopy-first group (1.21 ±0.54 vs.1.55 ±0.73,P =0.035).The total procedure time,propofol dosage and complications were similar between the two groups.Conclusion The bowel cleanliness of ileal-cecum portion in colonoscopy-first group is better than that of gastroscopy-first group during sequential bidirectional endoscopy in patients with propofol sedation.We propose colonoscopy first in patients with suspicious ileal-cecum lesion.
