OBJECTIVE To study the occurrence of patients′ respiratory system infection in ICU and its incidence influenced by nursing interference. METHODS The incidence of respiratory system infection of patients who were in ICU longer than 48 hours. were analyzed the normal nursing group with 461 cases from Jan to Dec 2006 were compared with the normal nursing with interference group with 490 cases from Jan to Dec 2007. So the results of two groups were compared by statistical analysis. RESULTS Twelve from 461 cases (the incidence of 2.6%) in normal nursing group had respiration system infection,vs 6 from 490 cases incidence of 1.2% in normal nursing with interference group. With nursing interference the incidence of patients′ respiration infection decreased obviously. There was significant difference between two groups (P

Objective:To prepare a quantified animal model of retinopathy of prematurity by economic and easy method. Methods:A total of 44 postnatal day 7 wistar rats were randomly assigned into 2 groups according to different oxygen inhalation concentration(n=22).Experimental group was exposed to 75% oxygen for 5 days,and them deprived of oxygen supply suddenly and exposured in air for 5 days.The Control group was exposed to room air in same experiment condition.The retinal vascular development and proliferation were evaluated by stretched preparation (ADPase stained retina)and eyeball cross-section,The expression of vascular endothelial growth factor(VEGF) was detected by immunohisto-chemical stain.Results: The central vessels became tortuous and constricted and the central avascular area increased in high-concentration oxygen environ-ment.But hypoxia environment made great vessels of retina broaden and abnormal curvature become obvious,neova- scularization was seen in the Experimental group.The average numbers of neovascular nuclei which breakthrough limiting membrane of amphiblestrodes in the Experimental group and the Control group were 32.800 0?0.767 8 and 2.750 0?0.716 4 respectively.Stain of VEGF was weaker in the control group than in the treated group.Conclusion:The rat modle of retinopathy of prematurity has powerful repeatability,high constancy and can be used in quantitative study.It is a suitable mode to study the pathogenesis and therapy of retinopathy of prema-turity.

Objective:To investigate the effects of hypoxia inducible factor-1?(HIF-1?)antisense oligonucleotides(ASODN)on the expression of vascular endothelial growth factor(VEGF)and retinal neovascularization in premature rat with retinopathy.Methods:A total of 80 postnatal day 7 wistar rats were randomly assigned into two group.The experimental group(n=40)were established as ROP mode group.The control group(n=40)was exposed to room air in the same experimental condition.HIF-1?ASODN was injected into rats'left cavum vitreum at 12、14、16 d in these two groups.Some of the experimental group were injected with saline at 14、16 d.So there were five groups of specimens including:normal eye(A),normal eye with HIF-1?ASODN(A1),ROP eye(B),ROP eye with HIF-1? ASODN(B1),ROP eye+saline(B2).The retinal vascular development and proliferation in five groups were evaluated by the retina stretch preparation of 15 newborn rats at 12、14、17 d respectively.Eyeball cross-section was staimed with hematoxylin and eosin(HE).The nuclei of proliferative retinal vessels of five groups were counted.The expression of VEGF and HIF-1?in retina by immunohisto-chemical stain were observed among all groups.Results:In ROP group(B)the central vessels became tortuous and constricted and the central avascular area increased at 12 d.At 14 d,neovascularization was seen,peaking at 17 d.ROP eye with HIF-1?ASODN(B1)presented the same as group A,but Neovascularization decreased obviously as compcured with group B.Retinal vessel shape of ROP eye+saline(B2)is same as group B.VEGF was mainly expressed in capillary endothelium endochylema and nucleus of ganglionic layer of retina and inner nuclear layer.The expressions of VEGF were weaker in group A, A1 than in group B,B2,with significant differences(P

For children suffering from primary nephrotic syndrome(PNS), podocyte is a crucial part of glomerular filtration barrier, whose injury usually causes proteinuria.The structural and functional integrity of podocyte cytoskeleton is the prerequisite of its normal physiological function.Recent studies demonstrated that under a certain pathological condition, B7-1, expressed in podocyte, can inhibit the activation of β1 integrin by competitively binding to the target site on the β1 integration, which may change the morphology and function of podocyte, consequently induced proteinuria.Other studies also have showed that abatacept, which selectively inhibit the cross-talk between B7-1 and β1-integrin,can reduce proteinuria in patients with B7-1-positive glomerular disease.These studies suggested that B7-1 may be a potential diagnostic biomarker and therapeutic target in proteinuria in PNS.This review summarizes the role of B7-1 expressed in podocyte in the pathogenesis of proteinuria and the possibility of clinical application in the future.

Objective:To investigate the curative effect of Chinese medicine foot bath combined with foot massage on diabetic peripheral neuropathy (DPN).Methods:Seventy-six patients with DPN who received treatment in Lishui Hospital of Traditional Chinese Medicine from July 2018 to December 2019 were included in this study. They were randomly assigned to undergo either Chinese medicine foot bath combined with foot massage (combined treatment group, n = 38) or Chinese medicine foot bath alone (single treatment group, n = 38) for 4 successive weeks in addition to diet and exercise management, medication for lowing blood glucose level, microcirculation improvement, and neurotrophic treatment. Before and after treatment, Toronto Clinical Neuropathy Score, Michigan Diabetic Neuropathy Score, and combined foot score were compared between the combined treatment and single treatment groups. The curative effect was also compared between the two groups. Results:After 4 weeks of treatment, Toronto Clinical Neuropathy Score [(5.82 ± 0.57) points, (7.62 ± 0.89) points], Michigan Diabetic Neuropathy Score [(14.92 ± 2.16) points, (18.01 ± 2.87) points], combined foot score [(3.17 ± 0.49) points, (4.41 ± 0.52) points] in the combined treatment and single treatment groups were significantly lower than those before treatment [(9.84 ± 1.27) points, (9.65 ± 1.21) points, (23.09 ± 4.03) points, (22.81 ± 3.92) points, (5.62 ± 0.85) points, (5.76 ± 0.73) points, t = 3.137, 2.361, 2.952, 2.392, 3.341, 2.427, all P < 0.05]. The declines in the combined treatment group were significantly greater than those in the single treatment group (all P < 0.05). Total effective rate in the combined treatment group was significantly higher than that in the single treatment group (94.74% vs. 78.95%, χ2 = 4.150, P < 0.05). Conclusion:Chinese medicine foot bath combined with foot massage is effective for DPN, which can significantly improve the clinical symptoms and promote the recovery of neurological function.

The present research aims to point out the long-existing defect of analyzing the spectrum diagram only from the perspective of haemodynamics instead of haemorheology. In the light of the theories of haemodynamics and haemorheology, the causes of spectrum diagram formation of carotid artery blood at the rapid and slow flow can be clarified completely and accurately. Four conclusions have been drawn in the end. As long as the velocity gradient is large enough, obvious red blood cells concentrate to the shaft even in the big or bigger blood vessels; the spectrum diagram is the powerful proof of the two phase flow model of blood; the spectrum diagram can be completely and accurately analyzed only by combining haemodynamics with haemorheology; and only when the red blood cells concentrate to the shaft, the big or bigger blood vessels can be regarded as haemogeneous fluid.
