Objective To analyze and investigate clinical characteristics, pathogenesis and treatment of urinary tract infection and aseptic meningitis. Methods Clinical features and laboratory tests of a two-month-old baby girl with urinary tract infection and aseptic meningitis were reported. Results The patient complained of fever, neck stiffness and a bulging fontanel, accompanied by congestion and abnormal secretion of urethra. The cerebrospinal lfuid (CSF) white blood cell count was 30×106/L. The blood culture and the CSF culture were both negative. And the urine culture was positive for Enterococcus faecium. The patient received a 10-day course of intravenous antibiotic therapy. The prognosis is good with no recurrence of the disease. Conclusions Aseptic meningitis can be concomitant with urinary tract infection, The probable hypothesis may be that sterile CSF pleocytosis is mediated by urinary tract infection. Knowledge of this may prevent unnecessary antibiotics therapy for presumed bacterial meningitis.

Objective To estimate fairness in the financial contributions of suburban households of Shanghai to the health system and the situation throughout the country. Methods A household survey was conducted to obtain data on health expenditure and government health input, which was then analyzed by means of the index for and methodology of fairness in the financial contributions of households in the performance assessment of the health system as introduced by the WHO. Results The coefficient of fairness in the financial contributions of households to the health system was estimated to be 0.735 and the rate of cooperative medical care coverage was positively related to the fairness. Conclusion The fairness level of the financial contributions of suburban households of Shanghai to the health system tallies with the level estimated by the WHO for China while the national level is lower. The calculations of government subsidy for household health, as recommended by the WHO in estimating fairness in the financial contributions to the health system, do not conform to the actual situation in China.

Objective To study the effects of joint optimization of CT scanning?modes and CTA starting?modes on the image quality, the patients' radiation doses and contrast volumes in cervicocerebral CTA. Method According to the date of examination from December 2013 to January 2014, 188 consecutive patients were prospectively selected and underwent cervicocerebral CTA using different CT scanning?modes and CTA starting?modes. These patients wererandomly divided into 4 groups:A1 (45 cases), A2 (48 cases), B1 (45 cases) and B2 (50 cases). Group A1 were Flash mode combined with test bolus, Group A2 were Flash mode combined with bolus tracking, group B1 were the common spiral scanning mode combined with test bolus and group B2 were the common spiral scanning mode combined with bolus tracking. The objective image quality evaluation criteria included the CT value comparison at the aortic arch (Pa1), carotid artery bifurcation (Pa2), basal artery (Pa3), superior vena cava (Pv1), internal jugular (pv2), transverse sinus (Pv3) and image objective noise. The subjective image quality assessments criteria included the contrast hardening artifact and diagnose acceptability. The radiation dose and contrast volumes of every patient were recorded and analyzed. The analysis of variance, the chi?square tests and the rank sum tests (Kruskal?Wallis) were used for data statistics. Results There were significant differences on the CT value at transverse sinus among the four groups, they were (124±30), (151±34), (130±37) and (160±37) HU, and different starting?modes had impacts on venous reflux (P<0.05), while scanning modes did not (P=0.162). There was no significant differences on the CT values at the other points among the four groups (P>0.05). The image noise had significant differences in four groups (P<0.05), the noise in Flash mode of dual?source CT were bigger than in the common spiral scanning mode. There was no statistically significant difference on diagnosis acceptability (P>0.05), however there were significant differences on contrast hardening artifacts (P<0.05) among the four groups. With the same scanning mode, the artifacts of group A1 were more serious than A2 and B1 were more serious than B2.There were significant differences on the patients' contrast volumes in the four groups (P<0.05), they were (45±5), (49±4), (35±4) and (35±4) ml, the contrast volumes in groups A1 and B1 were more than groups A2 and B2. There were significant differences among the four groups on patients' ED (P<0.05), which were (0.79 ± 0.07), (0.81 ± 0.08), (1.49 ± 0.11) and (1.51 ± 0.12) mSv. The radiation dose in groups A1, A2 were lower than those in B1 and B2. Conclusion The joint use of Flash mode and bolus tracking technique is recommended in application of cervicocerebral CTA, for its advantages of better image quality, good diagnosis acceptability, the patient's low radiation dose and low contrast volumes.

Objective To analyze the overall deployment of Class-A large medical equipments in China.Methods Data of Class A large medical equipments deployed from 2007 to 2015 were collected and classified regionally,for the purpose of measuring the overall deployment,growth level and plan performance.Results There were 403 large medical equipments in China,a rapid rise of deployment,yet still far below developed countries in terms of per capita deployment.Regional differences were significant.With PET-CT as an example,the plan performance in the east(92.19%)was much higher than the west of China(68.57%);plan performance of Class-A equipments was better,conducive to regulating the increase and distribution.Conclusions The deployment level of Class-A equipments in China is low in general,and calls for better regulation regardless of the planning and management progress.

Based on the results of oral glucose tolerance test( OGTT )and the levels of 1-h plasma glucose ( 1 hPG),793 subjects were classified into three groups:583 with NGTN ( normal 1 hPG in OGTT),127 with NGT1 H( higher 1 hPG in OGTT) and 83 with IGT( impaired glucose tolerance).NGT1H group had large waist circumference,higher body mass index,fasting plasma glucose( FPG),triglyceride,and lower high density lipoprotein-cholesterol than those of NGTN group.NGT1 H group had higher homeostasis model assessment insulin index ( 1.2 ± 0.6),lower homeostasis model assessment β3 ( HOMA-β ) (4.5 ± 0.7 ) and insulinogenic index (2.1 ±0.7) than those of NGTN group(0.5 ±0.6,4.8 ±0.7,2.7 ±0.9,respectively,all P ＜0.05 ).HOMA-β of NGT1 H group was higher than that of IGT group(4.5 ±0.7 vs.4.4 ±0.6,P ＜0.05 ).The results indicate that 1 hPG in OGTT may identify a condition of glucose metabolic abnormalities characterized by insulin resistance and reduced β-cell function.

Objective To explore the changes of expression of tight junction protein occludin in the brain microvascular endothelial cells of rats with acute necrotizing pancreatitis (ANP), and to study the relationship between the occludin expression and degree of pancreatic pathologic changes. Methods 80 rats were randomly divided into sham-operation (SO) group and ANP 3 h, 6 h, 12 h, and 24 h groups. Retrograde pancreatic duct injection of 5% choleate sodium in rats was used to establish ANP models. Pancreatic pathologic changes was evaluated. Immunohistochemistry, Western blot and RT-PCR were used to determine the expressions of the tight junction protein occludin in the brain microvascular endothelial cells. Results Occludin protein was linearly expressed along brain vascular vessels. The expression of occludin protein at 3h was 0. 35±0.09 in brain tissues from rats with ANP and 0. 49±0.08 in SO group, the expression of occludin mRNA were decreased from 1.50±0.30 to 1.01±0.18 (P < 0.05), the lowest expression rate occurred at 6 h, and the values in the two groups were 0. 26±0.07 and 0. 93±0. 19, respectively, the expressions of occludin protein and mRNA of ANP group at 12 h, 24 h were notably increased when compared with those at 6 h (P < 0. 05), but they were still lower than those in SO group (P < 0.05). The occludin protein and mRNA expressions were negatively related with the degree of pancreatic pathologic changes (Pearson correlation coefficient: -0.48 and -0.536, P < 0.05). Conclusions The expression of tight junction protein occludin decreased at both protein and mRNA level in brain microvascular endothelial cells of ANP rats. Furthermore, the expression of occludin was negatively correlated with pathological change of pancreas.

Objective To investigate the different concentrations of progesterone on the expression of a disintegrin and metalloprotease 10 (ADAM10),long form leptin receptor (Ob-R) and the secretion of soluble leptin receptor (SLR),leptin (LEP) in primary pregnancy human chorionic trophoblast cells. Methods Cultured primary human trophoblast cells and added in different concentrations of progesterone (0,100,150 and 200 ng/mL) for 24 hours. The relative expression of ADAM10 and Ob-R in the cells and the content of SLR and LEP in the supernatant were detected. Results With increasing concentrations of progesterone,early human trophoblast cells ADAM10 content gradual-ly decreased,the difference between the two groups was significant (P<0. 05). With increasing concentrations of progesterone,human chori-onic trophoblast cells in early pregnancy Ob-R expression levels increased, the difference was no statistically significant between each two groups (P>0. 05). SLR content of the cell supernatants as the concentration of progesterone increased and decreased,there are significant differences between each two groups (P>0. 05). LEP cell supernatant in each group with the increase of the concentration of progesterone concentration increased gradually between the two groups were significantly different(P>0. 05). Pearson’s test showed that the expression of expression SLR and LEP exists a significant negative correlation (R= -0. 949,P<0. 01). Conclusion Progesterone may influence the ex-pression of ADAM10,SLR and LEP by the regulation of leptin to participate GDM occurs.
