Objective To explore the clinical meaning of early systematic nursing intervention on the prevention of low limbs venous thrombus in ICU patients.Methods Totals of 120 patients in ICU were randomly divided into two groups by entering order number,odd numbers were experimental group(60 cases)and double numbers were control group(60 cases).Experimental group received early systematic nursing intervention while control group received ICU conventional nursing.All patients were measured the lower limb diameter per day,and were received colour Doppler examination to tested their femoral venous blood velocity in first,seventh and fourteen day of ICU,and their femoral venous blood velocity and incidence of low limbs venous thrombus were compared.Results No difference of femoral venous blood velocity in two groups was founded before intervention (P ＞0.05).After intervention,femoral venous blood peak velocity and average velocity of seventh and fourteen day in experimental group was(52.8 ± 9.6),(52.6 ± 8.8)and(34.2 ± 6.9),(35.3 ± 7.2),respectively,and higher than(41.3 ±7.8),(42.5 ±7.6)and(22.5 ±7.1),(23.7±6.6)in control group,differences between two groups were statistically significant(t =2.724,3.125,2.722,3.114 ;P ＜ 0.05); the incidence of low limbs venous thrombus in experimental group was lower than that of control group,and the difference was statistically significant(x2 =4.904,P ＜ 0.05).Conclusions Adopting early systematic nursing intervention can improve the femoral venous blood velocity,and effectively prevent and reduce the incidence of low limbs venous thrombus of ICU patients.

OBJECTIVETo explore the association between parental genetic polymorphism of methylenetetrahydrofolate reductase (MTHFR) 677C/T and occurrence of nonsyndromic cleft lip with or without cleft palate (NSCL/P) in offspring in Shandong Province.

METHODSMTHFR genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Parents of 89 NSCL/P patients treated at Qilu Hospital from August, 2006 to August, 2008 and those of 64 healthy children were recruited in this case-control study.

RESULTSFrequencies of T and C alleles in mothers of patients and healthy children were 65.73% and 46.09%, and 34.27% and 53.91%, respectively (Chi-square=13.663, P<0.01). Offspring whose mothers had T alleles were 2.243 times more likely to develop NSCL/P (95%CI: 1.408-3.572). Frequencies of T and C alleles in fathers of patients and healthy children were 62.92% and 55.47%, and 37.08% and 44.53%, respectively (Chi-square=2.222, P>0.05). The chance for parents of the patient and control groups to bear an affected fetus carrying homozygous mutations were 43% and 29%, respectively (P>0.05).

CONCLUSIONIn Shandong Province, maternal genotype for the MTHFR 677C/T polymorphism has a significant impact on the occurrence of NSCL/P in their offspring, whilst paternal genotype for this polymorphism may not be a risk factor for NSCL/P in their offspring.

OBJECTIVETo study the effect of oleic acid (OA) on expression of aquaglyceroporin genes, AQP3 and AQP9, in hepatocyte steatosis and to investigate the underlying molecular mechanisms using an in vitro system.

METHODSHepG2 cells were treated with OA at different concentration to establish in vitro models of nonalcoholic hepatocyte steatosis. The corresponding extents of hepatic steatosis modeling were assessed by oil red O staining and optical density (OD) measurements of the intracellular fat content. The model lines were then treated with inhibitors of the PI3K/Akt and p38 MAPK signaling pathway factors and effects on AQP3/9 expression was measured by real time RT-PCR and western blotting.

RESULTSThe fat concentration, indicative of hepatic steatosis, increased in conjunction with increased concentrations of OA (0 less than 250 less than 500 mumol/L). OA exposure also down-regulated AQP3 mRNA and up-regulated AQP9 mRNA levels in a concentration-dependent manner. The most robust changes in expression occurred in response to the 500 mumol/L concentration of OA for both AQP3 (0.47+/-0.18; t = 4.5450, P less than 0.05) and AQP9 (1.57+/-0.21; t = 3.0306, P less than 0.05). Treatment with OA + PI3K pathway inhibitor (LY294004) significantly decreased AQP9 mRNA expression (4.55+/-0.62) as compared to the control group (1.00+/-0.10; t = 9.7909, P less than 0.01), that 500 mumol/L OA group (2.43+/-0.53; t = 4.5018, P less than 0.05), and the LY294002 group (1.90+/-0.16; t = 7.1683, P less than 0.01). Treatment with p38 MAPK pathway inhibitor (SB230580) significantly increased the OA-suppressed level of AQP3 mRNA to the level detected in the control group (1.27+/-0.11; t = 5.7455, P less than 0.01) and decreased the OA-stimulated AQP9 mRNA (0.38+/-0.09; t = 6.5727, P less than 0.01). No significant changes in mRNA expression of AQP3/9 were observed with inhibition of the ERK1/2 and JNK signal transduction pathways. The OA-induced changes in protein expression levels of AQR3 and AQP9 followed a similar trend of the genes. Finally, OA suppressed the level of phosphorylated Akt (from 0.21+/-0.02 to 0.13+/-0.03; t = 3.8431, P less than 0.05) but elevated the level of phosphorylated p38 (from 0.58+/-0.06 to 1.02+/-0.10; t = 12.5289, P less than 0.01). Again, OA treatment produced no significant affect on ERK1/2 and JNK phosphorylation.

CONCLUSIONOA down-regulates AQP3 expression by stimulating the p38 MAPK signaling pathway, and up-regulates the AQP9 by blocking the PI3K/Akt pathway and activating the p38 MAPK signaling pathway.

OBJECTIVETo investigate the association of Graves' disease and Graves' ophthalmopathy with the C/T transition polymorphism at position -318 of promoter and the A/G transition polymorphism at position 49 of exon 1 within cytotoxic T lymphocyte associated antigen-4 (CTLA-4) gene.

METHODSThirty-three patients with ophthalmopathy of Graves' disease, fifty-six Graves' patients without ophthalmopathy and sixty normal subjects as control were involved in the present case-control study. The polymorphisms were evaluated by polymerase chain reaction fragment length polymorphism (PCR-RFLP). Comparisons were made of gene frequencies and allele frequencies between the groups.

RESULTSThe gene frequencies of CT and allele frequencies of T were much higher in Graves' patients with ophthalmopathy than that in the group without ophthalmopathy (P=0.020, P=0.019). The gene frequencies of GG and allele frequencies of G in patients with Graves' disease were significantly increased as compared with control group (P=0.008, P=0.007). The data suggest that smokers with Graves' disease seemed to be more predisposed to ophthalmopathy than non-smokers (P=0.018).

CONCLUSIONOur results suggest that an allele of T at position -318 of promoter is associated with genetic susceptibility to Graves' ophthalmopathy while an allele of G at position 49 of exon 1 is associated with genetic susceptibility to Graves' disease instead. Smoking is believed to be a major risk factor for ophthalmopathy.

Objective To approach the importance of nursing coordination of early arterial thrombolysis in acute cerebral infarction (ACI). Methods 37 cases of ACI early selective micro-catheter arterial thrombolytic therapy were observed and nursed after the standard preoperative preparation, intraoperative nursing coordination, postoperative condition observation and nursing care. Results 80.95% of 21cases had much improvement of symptoms after arterial thrombolytic therapy and care within 6h;68.75% within 6 ～ 24 h. The rate of disability in patients with ACI were significantly reduced and the quality of life of patients were improved.Conclusions Early selective micro-catheter arterial thrombolytic therapy is of benefit for the acute cerebral infarction patient. The standard preoperative preparation, intraoperative nursing coordination, postoperative condition observation and nursing care are essential.

Objective To investigate the effect of the continuous care support intervention on breast cancer patients with radical mastectomy.Methods Totals of 107 patients undergoing elective radical mastectomy were randomly divided into intervention group ( n =54 ) and control group ( n =53 ).Both of two groups of patients were treated on the basis of conventional care according to the doctors' advice before and after surgery.The intervention group received the continuous individual nursing intervention model,included preoperative interactive support intervention,postoperative pain assessment support intervention and rehabilitation support intervention after discharge. Intervention effects of two groups were observed and compared. Results The anxiety,positive response and negative response of two groups patients were no significant differences before intervention (P＞0.05).After intervention,the scores of anxiety,positive response and negative response in intervention group respectively were (35.28 ± 5.43 ),(39.82 ±4.03 ) and (25.61 ± 5.12),and that of control group were (42.73 ± 6.72),(33.15 ± 5.62) and (31.75 ± 6.38),and the difference was statistically significant ( t =6.313,7.065,5.495,respectively; P ＜ 0.01 ).The duration of postoperative different period pain score,first off the bed time,sleep time,upper extremity swelling and hospitalization days were statistically significant between two groups (P ＜0.01 ).And the postoperative recovery state of upper limb function after six months,and life quality score after one year in intervention group were significantly better than that of control group ( P＜0.01 ).Conclusions Continuous individualized specialized nursing intervention support model can promote physical function in patients with early recovery and improve quality of the prognosis life and the treatment outcome.

Objective To discuss the clinical effect of two-dimensional oral care for patients with mechanical ventilation by orotracheal intubation,and improve the quality of oral care.Methods Seventy inpatients with mechanical ventilation by orotracheal intubation from Feb 2011 to Jul 2012 in ICU were selected and randomly divided into experimental group (n ＝ 35) and control group (n ＝ 35).Experimental group was given two-dimensional oral care (oral swab just one time before intubation,and brush teeth and suction three times a day after intubation).Control group was given traditional oral care three times a day.Throat swab specimens were gathered for bacterial colony counts before intubation,and in 4 h,12 h,24 h,48 h after intubation,respectively.Bacteria quantitative culture was performed in sputum specimens and in throat swab specimens (one time per three days) after intubation.Oropharyngeal bacteria change and the incidence rate of ventilator associated pneumonia (VAP) were observed.Results Among all 70 patients,61 cases were valid,15 cases had VAP,and 8 cases died.In the experimental group,31 were valid,4 had VAP and 3 died,while in the control group,30 were valid,11 had VAP and 5 died.The difference of the incidence rate of VAP was statistically significant (x2 ＝ 4.643,P ＝ 0.040) and the difference of the incidence rate of death was not statistically significant (x2 ＝ 0.654,P ＝ 0.473).The difference of oropharyngeal bacterial colony counts had no statistical significance between two groups before intubation (t ＝-0.563,P ＝ 0.589),while the difference of oropharyngeal bacterial colony counts had statistical significance between groups in 4 h,12 h,24 h,48 h after intubation (t＝1.957,-2.520,-3.560,-2.165,respectively; P＜0.05).Conclusions Two-dimensional oral care can effectively reduce oropharyngeal bacterial colony,and decrease the incidence rate of VAP for patients with mechanical ventilation by orotracheal intubation.Thus it is a better nursing method to improve oral care quality.

OBJECTIVETo observe the difference of androgen and inflammatory cytokines level in atherosclerosis and analyse their relations.

METHODBoth carotid arteries and arteries of lower extremity were subjected to ultrasonic examination by Doppler's method. Those with much atheromatous plaque formation were ranged into case group, and those with normal result formed control group. Total, free testosterone and estradiol were assayed by radioimmunoassay. C reactive protein (CRP) was assayed by nepheloturbidity. Tumor necrosis factor-alpha (TNF-alpha), Interleukin-6 (IL-6), Interleukin-8 (IL-8), Interleukin-10 (IL-10), Interleukin-18 (IL-18), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were assayed by ELISA. The mean difference between two groups and the correlation between free testosterone and cytokines were analysed.

RESULTSFree testosterone was (6.337+/-3.371) pg/L in case group and (11.375+/-4.733) pg/L in control group, P<0.01. No differences were found in total testosterone and estradiol. CRP was (27.294+/-10.238) mg/L in case group and (12.843+/-6.318) mg/L in control group, P<0.01. IL-6 was (41.700+/-31.385) pg/L in case group and (25.396+/-20.772) pg/L in control group, P<0.05. IL-8 was (89.249+/-58.357) pg/L in case group and (67.873+/-31.227) pg/L in control group, P<0.05. sICAM-1 was (470.491+/-134.078) pg/L in case group and (368.487+/-97.183) pg/L in control group, P<0.01. sVCAM-1 was (537.808+/-213.172) pg/L in case group and (457.275+/-157.273) pg/L in control group, P<0.05. There were no differences in TNF-alpha, IL-10 and IL-18. Correlation analysis showed that FT (free testosterone) had negative correlation with CRP, IL-6 and sICAM-1. Among them FT had well correlation with CRP, correlation index was -0.678.

CONCLUSIONFree testosterone was in negative correlation with atherosclerosis in old-age male. Free testosterone may have the role of anti-atherosclerosis, and this effect was not achieved by its transformation to estradiol. Low free testosterone level was followed by increased level of inflammatory cytokines. Low free testosterones coexist with inflammation and they both affect the process of atherosclerosis in old-age male.

Analysis of serological and genetic characteristics on 2009 swine-origin influenza A (H1N1) virus (S-OIV) isolated from four patients with severe disease in Shenzhen were performed. Microneutralization assay showed that the neutralizing antibody titers of the infected patients did not exceed 1 : 20 in a short term post infection, which could not neutralize the viruses efficiently. Hemagglutination inhibition (HI) tests confirmed that the antigenicity of S-OIV from the patients was distinct from the seasonal influenza A virus, but similar to the reference strains of S-OIV. Phylogenetic and molecular analysis showed that S-OIV from the patients still belonged to the classical swine lineages and did not have the genetic characteristics of highly pathogenic influenza virus. Several amino acid residue mutations on HA protein were detected, which seemed not to affect the virulence and pathogenicity of the viruses. Further, A His 275 Tyr mutation on NA protein of a virus strain was detected, which induced the oseltamivir resistance of the virus.
