Objective To evaluate the effectiveness of a health education program based on the three level maternal and child health care networks in terms of acceptability of HIV tests in pregnant women. Methods A field study approach was adopted. Pregnant women in two sites who were similar in their social features were selected as intervention group and control group,respectively.Based on the baseline survey,the intervention group was exposed to one-year long health education activities on prevention of HIV related MTCT via lectures,broadcasting and educational materials etc.The effectiveness of the interventions was evaluated by interviewing the pregnant women in the two groups via questionnaires and comparing change of HIV test rates pre-and post-interventions. Results A total of 1 541 pregnant women were interviewed,with 933 women in the intervention group and 618 women in the control group.After one year intervention,the rate of HIV-testing during pregnancy in the intervention group was raised from 34.27% to 72.49%,while 5.83% to 20.38% in the control group.The rate of HIV-testing during pregnancy in the intervention group was 52.11% higher than in the control group (?2=24.60,P

Objective:To investigate the pathophysiological mechanism,clinical menifestation and radiographic diagnosis of cholesterol granuloma following chronic supperative otitis media.Method:Six cases of CG following chronic suppurative otitis media, confirmed by surgery and pathology,were reviewed and analyzed.Result:CG frequently accompanied with other middle ear diseases，and was shown as a high signal intensity on both T1-and T2-weighted images in magnetic resonance imaging(MRI).Conclusion:It was postulated that the obstruction of pneumatized temporal bone air cells,caused by other middle ear diseases such as cholesteatoma and tympanosclerosis,might be the pathophsiological mechanism of CG.The evaluations of computed tomography(CT) and clinical manifestation were limited to distinguish CG from cholesteatoma or other neoplasm,while the MRI can be of great value to characteristic diagnosis.

Objective To confirm the deviation between the present charge and real cost of nursing by comparing them between PICC and jugular veins catheter,and the advantages and disadvantages were weighed between them in tumor patients undergoing chemotherapy.Methods The cost of manpower,financial resources or materials for 106 patients with PICC,68 patients with jugular veins catheter were measured,accounted and statistically analyzed with the ladder sharing method for project cost.Comparing the cost between calculation cost and current charging standard,and the cost and clinical application was studied.Results The real cost of PICC was (2259.99±30.99)Yuan and current charging standard was 1532.79 Yuan,the deviation was -727.20 Yuan,and the real cost of jugular veins catheter was (393.86±33.93) Yuan,and current charging standard was 292.13 Yuan,the deviation was -101.73 Yuan.The complication rate was 12％ in PICC,17％ in jugular veins catheter.The real cost of nursing on PICC and jugular veins catheter was higher than current charging standard,and the real cost of single nursing on PICC was 5.74 times higher than jugular veins catheter.The cost remains unchanged with 4～6 course of chemotherapy treatments in a year.Conclusions The advantages of PICC are more than jugular veins catheter,so the preferred choice is PICC,and jugular veins catheter comes secondary.

Objective To establish the real-time fluorescence quantitative PCR method for the detection of bifidobacteria in human fecal samples, and to provide an effective means for measuring intestinal bacteria. Methods Total DNA of bacteria was extracted from 60 cases of children's fecal samples. Three primers of bifidobacteria based on the 16S ribosomal RNA (16SrRNA)which possessed specialities of bacteria as amplified region were designed.The part of amplified 16SrRNA gene sequences was used as standard production.The serial dilution of standard was analyzed to build an absolute quantitative standard curve with SYBR GreenⅠ dye method, and the bifidobacterium contents in sixty human fecal samples were calculated. The sensitivity of the reaction was calculated by detecting the lowest detectable standard which determined the sensitivity of the reaction. The PCR products’melting curve was used to evaluate the specificity.The coefficient of variation (CV)of different batches of standard with the same concentration was used to evaluate the stability of reaction.Results The length of PCR product fragment which was used to build the standard curve was about 6 1 3 bp, the sequencing result was consist with the goals, and the standard sample of bifidobacteria was successfully established in real-time fluorescence quantitative PCR.The standard curve showed a good linear relationship with R2=0.999.The minimum detection value was 1.48×102 copies per reaction.The melting curve of real-time fluorescence quantitative PCR was a single peak.The test samples were batched and then examined by fluorescence quantitative PCR.The CV of standards’ Ct values which calculated from the standard (1.48 × 103 -1.48 × 107 copies · μL-1 )were 2.94%, 3.39%, 3.54%,3.08%,and 3.34%,respectively.The contents of bifidobacteria in fecal from 60 children was 7.77± 0.86(copies · g-1 wet fecal)transformed by logarithmic.Conclusion The established real-time fluorescence quantitative PCR method has high sensitivity, strong specificity and good repeatability, which is suitable for detection of human fecal bifidobacteria content.

Objective To evaluate the expression of substance P (SP) and caltenin gene related peptide (CGRP) in esophagueal mucosa from patients with non-erosive gnstroesophageal reflux disease (NERD) and reflux esophagitis (RE) and to explore their role in the development of NERD. Methods Fif-ty-one patients with typical symptoms of gnstroesophageal reflux disease (GERD) were evaluated with reflux disease questionnaire (RDQ), PPI test, endoscopy and 24hr esophageal pH monitoring. The patients were then divided into RE group (n = 21), NERD group with acid refluux (NERD+, n = 12) and NERD group without acid reflux (NERD-, n = 18) according to the evaluation results. The expression of SP and CGRP in esophagus mucosa from these patients and 10 healthy control subjects were assayed by immunohistochemis-try, and the stain positive index (PI) was calculated by Color patho-image analysis software and compared. Results The PIs of SP and CGRP in NERD- group were 96.77±31.74 and 24.76±29.15, respectively, which were significantly higher than those of NERD+ group (73.64±31.38, 9.78±10.30, respectively, P < 0.05), RE group (67.56±34.62, 9.61±6.20, respectively, P < 0.05) and control group (59.82± 46.15, 8.64±12.12, respectively, P < 0.05). Conclusion Expressions of SP and CGRP in esophagus mucosa from NERD patients without detectable acid reflux are significantly increased, they may play an im-portant role in esophageal visceral sensitivity.

Objective To investigate the sleep structure of children with attention deficit hyperactivity disorder (ADHD) and the differences among subtypes of ADHD.Methods Ninety children with ADHD were diagnosed in Department of Neurology, the Children's Hospital Affiliated to Capital Institute of Pediatrics between June 2012 and June 2013, including 75 boys and 15 girls,6-14 years old [(9.5 ± 2.4) years old], and among them there were 55 cases of ADHD-combined type, 25 cases of ADHD-inattentive type, and 10 cases of ADHD-hyperactive impulsive type.Thirty healthy children whose age and sex matched with ADHD group,came from Beijing and the surrounding area,were selected as the healthy control group,including 23 boys and 7 girls,6-14 years old [(9.2 ± 2.9) years old].Two groups underwent full overnight sleep assessment.Results The latency of rapid eye movement(REM) in children with ADHD was (146.58 ± 47.28) minutes, and the sleep latency was 19.00 minutes [(8.25-37.50) minutes];while the latency of REM in healthy control group was (87.55-± 13.59) minutes, and the sleep latency was 9.00 minutes [(3.50-13.63)minutes].Compared with healthy control group, children with ADHD demonstrated the increased latency REM and sleep latency, and decreased sleep efficiency,the increasing times of awakening and total duration,and these differences were all statistically significant(all P ＜ 0.05).The percentage of non-rapid eye movement(NREM) phase Ⅱ in ADHD hybrid was lower than the ADHD attention-deficit(t =2.012,P ＜ 0.05).Sleep latency in ADHD attention-deficit was longer than the ADHD hybrid(t =2.964,P ＜ 0.05).No statistical differences were found among the various types in other indicators.The prevalence of periodic limb movements in sleep(PLMS) was 27.78％ (25/90 cases) in ADHD group and the prevalence of PLMS was 3.30％ (1/30 cases) in the healthy control group.The differences in prevalence between 2 groups were statistically significant (x2 =8.053, P ＜ 0.05).Conclusions Children with ADHD significantly display more problems with sleep.Sleep latency and NREM Ⅱ are different between ADHD attention-deficit and ADHD hybrid.
