As the dressings currently used in clinic settings unflat shape in general, they can't be fitted completely on occiput, heel, elbow, knee and other body parts unflat. This paper developed one kind of foam dressing of special shape based on local anatomy. The foam dressing is waterproof and air permeable, it can cover the wound closely enough to prevent bacteria from invasion and infection. With a saturated absorption ratio of 1: 8 or higher, it can keep the wound clean and moisture by absorbing large amounts of wound inflammatory secretions and is almost completely permeable to oxygen and carbon dioxide. Assuring safety and effect meanwhile, it has better outcomes than common dressings in the same application settings.

Objective To observe the effect of nerve growth factor(NGF)and electro-acupuncture(EA) on learning and memory in rats with cerebral ischemia.Methods An experimental model of cerebral ischemiareperfusion was established in 40 rats,who were then randomly divided into a model group,a sham operated group,a NGF group,an acupuncture group and a NGF plus acupuncture group.Three weeks were allowed for the recovery of the blood-brain barrier lesion caused by ischemia-reperfusion before intravenous injection of NGF(10μg/kg,once daily for 15 days)via the vena caudalis.In the two acupuncture groups,this was administered in combination with EA at the Baihui(DU20)and Yamen(DU15)acupoints(frequency 100 Hz,2 mA,20 min/time,once daily for 15 days).Morris' water maze test was used to assess any changes in spatial learning and memory abilities.Results The ischemic rats showed significant learning and memory disorders compared with the sham-operated group.In the NGF group,the rats' learning and memory abilities did not impmve significantly compared with the model group and the EA group.Significantly better learning was observed in the NGF+EA group compared with the model group,the EA group and the NGF group.Conclusion NGF combined with EA can improve the learning and memory abilities of rats with learning and memory dysfunction caused by cerebral ischemia-repedusion.

Objective To investigate the correlations of serum total bilirubin level with infarct volume,severity and etiological typing in patients with acute ischemic stroke.Methods Patients with acute ischemic stroke admitted to hospital from January 2012 to January 2014 were used as subjects of study.Their clinical and imaging data were collected,and serum total bilirubin levels were detected.The correlations of the serum total bilirubin levels with the infarct volume,severity and etiological typing were analyzed.Results A total of 290 patients with acute ischemic stroke were enrolled in the study.The patients were divided into either a large infarction group (≥1.8 cm3,n =145) or a small infarction group (＜ 1.8 cm3;n =145)according to the median cerebral infarction volume.The total bilirubin level of the large infarction group was significantly higher than that of the small infarction group (16.896± 7.761 μmol/L vs.13.039±4.477 μmol/L;t =5.185,P ＜ 0.001).Multivariate logistic regression analysis showed that the bilirubin highest quantile group (＞ 17.893 μmol/L) was an independent risk factor for large infarction (odds ratio [OR] 2.754,95％ confidence interval [CI] 1.028-7.375;P =0.044).According to the National Institutes of Health Stroke Scale (NIHSS) score,the patients were divided into a mild stroke group (NIHSS score ＜8;n =210) and a moderate to severe stroke group (NIHSS score≥ 8,n =80).The total bilirubin level of the moderate to severe stroke group was significantly higher than that of the mild stroke group (16.861 ±7.689)μmol/L vs.14.246 ± 6.019 μmol/L;t =3.052,P =0.002).Multivariate logistic regression analysis showed that the total bilirubin level was not an independent risk factor for moderate to severe stroke.Small artery occlusive stroke,large artery atherosclerotic stroke,and other definite causes of stroke were combined into non-cardioembolic stroke group (n =244).The total bilirubin level in the cardioembolic stroke group (n=46) was significantly higher than that in the non-cardioembolic stroke group (19.639±8.409 μmol/L vs.14.087 ±5.831 μmol/L;t =5.479,P＜0.001).Multivariate logistic regression analysis showed that the bilirubin highest quartile group (＞ 17.893 μmol/L) was an independent risk factor for cardioembolic stroke (OR 8.405,95％ CI 1.719-41.106,P =0.009).Conclusions The increased serum total bilirubin level is an independent risk factor for larger infarction and cardioembolic stroke.As an oxidative stress index,serum total bilirubin in acute stage can provide help for early identification of infarct volume and etiological subtype in patients with ischemic stroke.

Objective: To explore current status of antithrombotic therapy in patients with non-valvular atrial ifbrillation (NVAF) at Macau area of china via clinical data analysis.
Methods: A total of 472 NVAF patients treated in Centro Hospitalar Conde de S?o Januário (CHCSJ) from 2014-01 to 2041-12 were enrolled. The patients were at the age of (73.0±10.9) years including 197 (41.7%) female and 244 (51.7%)≥75 years. The baseline condition, clinical characteristics and antithrombotic therapy were analyzed; relevant scores were calculated, CHA2DS2-VASc score≥2 was deifned as high risk of stroke and HAS-BLED score≥3 was deifned as high risk of bleeding.
Results: The average CHA2DS2-VASc score was (3.4±1.8) and 389/472 (82.4%) patients with CHA2DS2-VASc scor≥2; the mean HAS-BLED score was (1.96±1.03) and 132 (28.0%) patients with HAS-BLED score≥3. There were 184 (38.9%) patients received antiplatelet therapy, 101 (21.4%) received warfarin, 156 (33.1%) received new oral anticoagulant drug and 22 patients taken both antiplatelet and anticoagulant treatments simultaneously; 53 (11.2%) patients had no antithrombotic therapy. The patients with high risk of stroke had the higher rate of anticoagulant therapy (215/472, 55.3%) and the application rate of new anticoagulant drug was higher than warfarin.
Conclusion: NVAF patients had the higher risk of stroke as more than 80% with CHA2DS2-VASc score≥2 and most patients received anticoagulant therapy in Macau area. The application rate of new anticoagulant drug was higher than warfarin.

ObjectiveTo investigate the correlation of radial artery and serum osteoprotegerin (OPG) expression and vascular calcification in patients with end stage renal disease.MethodsDiscarded radial arteries were gathered from 43 patients with end stage renal disease(end stage renal disease group)during arterial venous fistula plasty,including 24 patients with no calcification,13 patients with mild to moderate calcification and 6 patients with severe calcification,20 patients with dialysis and 23 patients without dialysis.Discarded arteries from 9 patients with upper limb trauma were chosen as control group.The yon Kossa staining,alizarin red staining and OPG immunohistochemical staining were taken and serum OPG level was measured for all the patients.ResultsSerum OPG level was significantly higher in end stage renal disease group than that in control group [(216.47±83.78) ng/L vs.(57.15±23.22) ng/L,P＜ 0.01 ].Serum OPG level in patients with no calcification,mild to moderate calcification and severe calcification[ ( 152.21±32.21 ),(248.31±53.86),(368.44±53.57) ng/L] and OPG staining value ( 1,2,4 scores) were increased gradually as vascular calcification more serious (P＜ 0.01 ).There was a positive relationship between serum OPG and vascular calcification value(alizarin red staining:r =0.517,P ＜ 0.01 ; yon Kossa staining:r =0.677,P＜ 0.01 ).Serum OPG level and OPG staining value in patients with dialysis were higher than those in patients without dialysis [ (283.57±79.02 ) ng/L vs.( 152.46±30.89 ) ng/L,2 scores vs.1 score,P ＜ 0.01 ].ConclusionsThere is relationship between serum OPG level,OPG expression of radial artery and vascular calcification.

Objective To investigate the relationship between serum or urine tissue inhibitor of metalloproteinases-1 (TIMP-1)levels and the stages of chronic kidney disease (CKD).Methods Serum and urine level of TIMP-1 were measured by enzyme-linked immunoadsorbent assay (ELISA) in 122 CKD patients and 40 healthy controls.Serum cystatin-C (CystC),parathyroid hormone (PTH),low-density lipoprotein (LDL)and other markers were determined simultaneously.Correlationanalysis between TIMP-1 level and degree of renal function were performed.Results Serum and urine TIMP-1 of the patients in CKD group was significantly higher than that in control group (P

ObjectiveTo investigate key techniques and intervention in reducing birth defects. Method Down's syndrome (DS), trisomy-18 (Edwards syndrome, ES), neural tube defects (NTD), Duchenne muscular dystrophy (DMD), spinal muscular atrophy (SMA), thalassemia, and glucose-6-phosphate dehydrogenase deficiency (G6PD) were chosen as target disease. From Jan. 2007 to Dec. 2009, the condition of intake folie acid were investigated in 5004 pregnant women in Panlong District and Wuhua District of Kunming City. All of the 27 660 pregnant women undergoing prenatal examination were enrolled into the study from the First People's Hospital of Yunnan Province, the Second People's Hospital of Yunnan Province, the First People's Hospital of Qujing City, the Second People's of Qujing City, Qujing Women and Children's Hospital, People's Hospital of Lincang City, Kunming Maria Women's Hospital, Maternal and Infant's Care Unit of Panlong District of Kunming City, Maternal and Infant's Hospital of Dali City. The screening was performed on serum of those pregnant women at 8 -20 +6 gestational weeks. Prenatal cytogenetic analysis and fetal ultrasonogrspy were performed on the high risk or indicated women after genetic counseling. DNA analysis was administered on those women with family or childbearing history of DMD,SMA,thalassemia,orG6PD. Outcomeof pregnancywasfolloweduptoevaluatetheeffectof intervention. ResultsApproximately 30. 10％ (1506/5004) of pregnant women were administered by oral folic acid during perinatal period. Two thousand three hundred and thirteen women with high risks of DS,ES, or NTD fetuses were observed among 27 660 undergoing maternal serum screening. Two thousand and ninety-six pregnant women including two twins pregnant women were performed cytogenetic analysis. Other 67 pregnant women at high risk of DMD, SMA, thalassemia, and G6PD accepted genetic counseling and prenatal gene analysis. Two thousand one hundred and sixty-three pregnant women (2165 fetuses) underwent prenatal examination. One hundred and two cases chromosome abnormalities, 17 cases NTD, 4 cases DMD, 1 cases α-thalassemia major were found. All of the 91 fetuses with major birth defects were terminated after genetic counseling. Another affected DS fetus in a twin pregnancy dead intrauterine at 24 gestational weeks. Thirty-two women bearing fetuseswithbalancedtranslocations orinversionscontinuedtheir pregnancies. Totally 2071 normal term fetuses were born in the prenatal diagnosis group. Two fetuses with normal chromosome were lost within 1 week after amniocentesis. Four affected DS fetuses were born from their high risk mothers who refused further prenatal diagnosis service. In a random sampling follow-up cohort of 5000 mothers at low risk, none of affected child suffering target diseases was found. The DS detection rate of maternal serum screening was 84％ (27/32), with the false positive rate was 6. 153％ (1702/27 660).ConclusionsFolic acid intake before conception and in the first trimester would reduce the risk of birth defects, only 1/3 reproductive women took folie acid actively. Maternal serum screening could effectively detect high risk of DS, ES and NTD. The genetic counseling is critical in women at high risk or who had family history of inherited disorders. The prenatal screening and diagnosis combined with routine obstetric care could reduce the incidence of major birth defects, which should become prenatal care strategy in our country.

Background: Ferroptosis, which is caused by an iron-dependent accumulation of lipid hydroperoxides, is a type of cell death linked to diabetic kidney disease (DKD). Previous research has shown that fatty acid binding protein 4 (FABP4) is involved in the regulation of ferroptosis in diabetic retinopathy. The present study was constructed to explore the role of FABP4 in the regulation of ferroptosis in DKD. Methods: We first detected the expression of FABP4 and proteins related to ferroptosis in renal biopsies of patients with DKD. Then, we used a FABP4 inhibitor and small interfering RNA to investigate the role of FABP4 in ferroptosis induced by high glucose in human renal proximal tubular epithelial (HG-HK2) cells. Results: In kidney biopsies of DKD patients, the expression of FABP4 was elevated, whereas carnitine palmitoyltransferase-1A (CP-T1A), glutathione peroxidase 4, ferritin heavy chain, and ferritin light chain showed reduced expression. In HG-HK2 cells, the induction of ferroptosis was accompanied by an increase in FABP4. Inhibition of FABP4 in HG-HK2 cells changed the redox state, sup-pressing the production of reactive oxygen species, ferrous iron (Fe2+), and malondialdehyde, increasing superoxide dismutase, and reversing ferroptosis-associated mitochondrial damage. The inhibition of FABP4 also increased the expression of CPT1A, reversed lipid deposition, and restored impaired fatty acid β-oxidation. In addition, the inhibition of CPT1A could induce ferroptosis in HK2 cells. Conclusion Our results suggest that FABP4 mediates ferroptosis in HG-HK2 cells by inhibiting fatty acid β-oxidation.
