Objective To evaluate the relationship between the cervical length,the test of fetal fibronectin and premature birth in pregnant woman.Methods Fetal fibronectin in sample of cervical secretion was tested using the reagent box of FFN manufactured by the ADEIA company of the United States and enzyme-labeled immunosorbent assay(ELISA) methods in 110 pregnant women.They were divided into two groups:first group,there were 60 cases who had symptom of aura prematurity and cervical lengths ≤30 mm monitored by trans-perineum ultrasound.second group was 50 normal pregnant women.Results The postive rate of fetal fibronectin was higher significantly in first group than that in second group.Conclusion The measurement of cervical lengths by the trans-perineum ultrasound and the test of Fetal fibronectin in pregnant women who has symptom of aura prematurity are of certain clinical value in predicting preterm birth.

Objective We tried to investigate the current status of pediatric nursing post setting and analyze the practical application effect in the clinical working practice for the foundation of readjusting and setting up the pediatric nursing positions.Methods By convenient sampling method,the general condition and current post setting situation in the pediatric wards of 7 hospitals with self-designed questionnaires were investigated.The results underwent analysis Results The nursing post setting in pediatric wards of 7 hospitals were not all the same,nursing posts in the pediatric ward included three categories:management positions,teaching positions and clinical positions.Management positions included the head nurse,deputy head nurse and head nurse assistant; teaching positions included the teaching secretary and clinical total teaching nurse; the seven kinds of clinical nursing positions were office job,day shift,night shift,evening shift,midnight shift,late-morning shift,auxiliary job.Though some nursing jobs differed in the position names and working hours,their job contents were nearly identical.Conclusions Pediatric nursing post setting management in our country is still in the exploratory stage at present,it has not form a unified perfect job management system.Pediatric nursing positions should be set from the perspective of evidencebased theory,satisfying the demands of patients as the guidance,coming from clinical needs as the first principle,in the full implementation of the accountability for nursing and based on comprehensive consideration of various factors,so that the post setting can be scientific and reasonable.

Objective To assess the role of intervention of dexmedetomidine in lung tissue and plasma of septic rats induced by lipolysaccharide.Methods Forty SD rats weighing 250-300 g were divided into 4 groups:control group (n =10)with saline (1 ml·kg-1·h-1 )infused through the tail veins of rats for 6 h;dexmedetomidine (DEX)group (n =10)with dexmedetomidine,injected 6.5 μg ·kg-1·h-1 for 10 min followed by 5 μg·kg-1·h-1 ,continuously infused through tail veins for 6 h;li-polysaccharide (LPS)group (n = 10 )with lipolysaccharide (7.5 mg/kg)infused through the tail veins of rats;LPS+DEX group (n =10),after infusion of LPS,rats were treated with dexmedeto-midine (bolus 6.5 μg·kg-1·h-1 ,10 min;5 μg·kg-1·h-1 ,continuous infusion)through the tail veins for 6 h.ELISA and Western blot were performed to assess the protein expression of IL-1,IL-6, TNF-αand TLR4;the wet/dry ratio (W/D)of lung tissue in each group was measured and the injury scores were recorded through the Murakami method.Results There was no statistical significance between the control group and DEX group in plasma level of inflammatory factors,pulmonary TLR4 expression,wet/dry ratio and injury score of lung tissues,however,compared to the control group, there was a significant elevation in the above-mentioned biomarkers,W/D and injury score of lung tis-sue (P <0.01).Compared to the control group,there was no statistical significance in the LPS+DEX group.Compared to the LPS+DEX group,the biomarkers mentioned above,W/D and injury score of lung tissues were significantly elevated in the LPS group (P <0.01).Conclusion The irrita-tion of LPS can trigger the elevation of inflammatory factors in plasma,TLR4 expression in lung tis-sues in rats,while the intervention of dexmedetomidine can significantly alleviate this tendency. Dexmedetomidine can suppress the inflammatory reaction and pulmonary edema in septic rats.

Background Intracranial vascular malformation causes different neurophthalmological symptoms and signs due to oppressing visual-related tissue and cranial nerves after hemorrhage.However,there is no availably systematic clinical research on this disease up to now.Objective This retrospective cases analysis was to explore the neurophthalmological features of intracranial vascular malformation.Methods The clinical datas were collected from 100 cases with intracranial vascular malformation in Affiliated Third Hospital of Sun Yat-sen University from June,2007 to June,2013.The neurophthalmological clinical features including general condition,initial symptom,concomitant symptoms and image results were retrospectively surveyed.Results Neurophthalmological symptoms and signs were found in 20 patients with intracranial vascular malformation by CT and MRI with the detectability 20％ (20/100).The main neurophthalmological symptoms were visual field defect (50％,10/20) and vision loss (45％,9/20).The neurophthalmological signs were pupil abnormalities (35％,7/20).Other neurophthalmological features included optic nerve atrophy (5 ％,1/20),papilloedema (5 ％,1/20) and oculomotor nerve palsy (5 ％,1/20),etc.The relevant cranial diseases included cerebral arteriovenous malformation in 60％ patients (12/20),cavernous angiomas in 35％ (7/20) and venous malformation with cavernous angiomas (1/20).The lesions of cerebral arteriovenous malformation were located in occipital lobe (4 cases),parietal-occipital area (3 cases),temporal lobe (3 cases) and frontal lobe (1 case),midbrain area (1 case) ; while those of cavernous angiomas were located in parietal lobe (1 case),occipital lobe (1 case),gyrus cingulated area occipital lobe (1 case),carvenous sinus (1 case),temporal lobe (1 case),parietal-temporal area (1 case) and pons area (1 case).Intracranial hemorrhage occurred in 14 patients in subarachnoid space (6 cases) and brain (8 cases).Conclusions The patients with intracranial vascular malformation have different neurophthalmological symptoms and signs.Sufficient attention should be paid to the patients with neurophthalmological symptoms and signs.

Objective:To compare the anti-obesity effect of green tea and black tea polyphenols and investigate their molecular mechanisms. Method:Rats were divided randomly into four groups:control group,high-fat group,high-fat diet with green tea polyphenols(GTP) supplement group,and high-fat diet with black tea polyphenols(BTP) supplement group. Body weight was determined every 2 w. After 3 months,the changes of epididymal fat tissues weight and serum lipids were observed. Expressions of those genes associated with adipocyte differentiation in epididymal fat tissues of rats were measured by real-time transcription-polymerase chain reaction,including pref-1,aP2,TNF-?,leptin,PPAR-?,C/EBP-? . Results:Both GTP and BTP prevented the increase of body weight and fat induced by high-fat diet and profoundly down-regulated those adipocyte-specific genes,including aP2,TNF-?and leptin. In addition,GTP also up-regulated the pre-adipocye marker — pref-1 and reduced the expression of transcription factor,peroxisome proliferators-activated receptor(PPAR-?) . Conclusion:Tea polyphenols could prevent obesity by reversing the adipocyte differentiation,and GTP possessed stronger inhibitory effect than BTP.
