Objective To ensure the quality of disinfection and sterilization of the fiberbronchoscope in the sterilesupply center through the implementation of whole life cycle management.Methods Using the historical comparative method,the fiberbronchoscopes managed by the departments were enrolled into a control group from February 2013 to March 2014,and the ones undergoing life-cycle management in the sterile supply center were involved in an observation group from April 2014 to May 2015.The two groups were divided according to the management subject and mode,and compared from the aspects of treatment flow,process quality control and record tracing validity.All the data were input with Excel sheet,andanalyzed statistically with SPSS 17.0.Results The observation group and the control group had the numbers of positive results in internal cavities,positive results in external surface,damaged or irrationally-placed package,invalid data tracing and non-standardized storage being(0,1.11±0.15),(0,1.09±0.20),(1.07±0.13,2.75±0.22),(0.57±0.03,1.53±0.31) and (0.13±0.07,0.95±0.21) respectively,and the differences between the two groups were significant (P＜0.05).The turnover of the fiberbronchoscope was enhanced significantly in the observation group when compared with that in the control group.Conclusion Life cycle management contributes to strengthening quality control of the treatment of polluted fiberbronchoscope,and decreases the incidences for hospital infection.

Objective To explore the effect of specific nursing on quality of life of the parents of children with mental retardation (MR). Methods 160 parents of children with MR and 160 parents of normal children were evaluated with WHO Quality Of Life-BREF (WHO-QOL-BREF). The children with MR were divided into observation group (n=80) and control group (n=80). The control group received the traditional nursing care, and the observation group accepted specific nursing care. The scores of WHOQOLBREF were compared. Results The score of WHOQOL-BREF was lower in the MR group than in the normal group (P<0.01). The score decreased with the aggravation of MR (P<0.001). The score of WHOQOL-BREF was higher in the observation group than in the control group (P<0.01). Conclusion Specific nursing should be given to the parents of children with MR, which can promote their quality of life.

The paper described the practice of contingency nursing management for ICU wards in case of power breakdown in the hospital The SICU wards have developed their power failure contingency plan in which the nurses on duty are divided into Group A,B and C according to their positions and qualifications.Respectively,they take charge of patient safety,coordination and command,and medical aid.We also established the procedure of emergency response for these duties.Training and examination familiarize the medical personnel with the procedure and their duties.Four practices proved that the implementation of the plan reduces risks exposure and improves the satisfaction.With the contingency plan,the nurses in ICU can now take care of critical incidents and avoid nursing risks in ICU efficiently.

Objective To determine the role of fosinopril and valsartan intervention in Klotho, matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1) and plasminogen activator inhibitor (PAI-1) gene expression in hypertensive renal interstitial fibrosis (RIF) in the kidney tissue of spontaneously hypertensive rats (SHR). MethodsWe randomly divided 20 male 22-week-old SHR into 4 groups (5 in each group):a hypertension group (SHR group), a fosinopril group ［Fos group, 10 mg/( kg·d) gavage］, a valsartan group ［Val group, 10 mg/( kg·d) gavage］， and a fosinopril plus valsartan group ［Fos + Val group, fosinopril 10 mg/( kg·d) + valsartan 50 mg/( kg·d) gavage］. Another five 22-week-old male Wistar Kyoto rats (WKY) were used as controls. Through monitoring the weight of the rats, tail artery pressure, 24-hour urine protein by fosinopril and/or valsartan intervention after the 8-week trial. RT-PCR and Western blot were used to detect the mRNA and protein expression of Klotho, MMP-9, TIMP-1, and PAI-1 in the kidneys.Results RT-PCR showed that in the SHR group, Klotho mRNA and protein expression were significantly decreased(P＜0.01), while mRNA and protein expression of MMP-9, TIMP-1, and PAI-1 were significantly higher compared with the WKY group(P＜0.01). With fosinopril and / or valsartan intervention, Klotho mRNA expression in the Fos group (P＜0.01), Fos + Val group (P＜0.01), Val group (P＜0.05), Klotho protein expression in the Fos group(P＜0.05), Fos + Val group (P＜0.05), Val group (P＜0.01), were significantly increased compared with those in the SHR group. The mRNA and protein expression of MMP-9, TIMP-1, and PAI-1 in the Fos group, Val group, and Fos + Val group were significantly lower than those in the SHR group (P＜0.01). The expression of Klotho mRNA had negative correlation with the expression of MMP-9 mRNA (r= -0.864, P<0.01), TIMP-1 mRNA (r=-0.725, P<0.01) and PAI-1 mRNA (r=-0.785, P<0.01). The Klotho protein expression had negative correlation with the expression of MMP-9 protein (r=-0.614, P<0.05), TIMP-1 protein (r=-0.579, P<0.05), and PAI-1 protein (r=-0.552, P<0.05). Conclusion Anti-aging gene Klotho and the genes related with extracellular matrix degradation gene MMP-9, TIMP-1, PAI-1 are involved in hypertensive renal injury. The expression of Klotho and MMP-9, TIMP-1, and PAI-1 is closely correlated. Fosinopril and valsartan which increase the Klotho mRNA and protein expression can alter the expression of Klotho-MMPs/TIMPs, which may be the main mechanism to prevent interstitial fibrosis.

Objective To explore the correlation of the throid function and malnutrition in maintenance hemodialysis(MHD) patients.Methods Fifty-four MHD patients and 16 normal controls were enrolled as our subjects and named as MHD group and control group.Serum concentrations of total triiodothyronine (TT3),total thyroxine (TT4),free thyroine (FT4),free triiodothyronine (FT3),and thyroid-stimulating hormone (TSH) were measured by enhanced chemiluminescence immunoassay.Their anthropometry,biochemical assays,malnutrition-inflammation score (MlS) and micro-inflammation parameters such as high sensitivity C-reactiveprotein(hs-CRP) were also measured.Results Serum T3,FT3,T4,FT4 concentration in MHD patients were (1.18 ±0.31) nmol/L,(2.61 ±0.62) pmol/L,(100.00 ± 19.96) nmol/L,(8.56 ±0.85) pmol/L respectively,lower than that of control group ((2.95 ± 0.27) nmol/L,(7.12 ± 0.94) pmol/L,(136.25 ± 19.68) nmol/L,(8.89 ± 0.56) pmol/L respectively,P ＜ 0.01).while there was no significant change on TSH (P =0.058).According to albumin nutrient grading standard:the morbidity of malnutrition was 75％ (39/54).The morbidity of malnutrition was 100％ based on the criteria of MIS.Of which,mild malnutrition rate was 29.63％ (16/54),moderate rate for 37.04％ (20/54) and sever rate for 33％ (18/54).The levels of serum creatinine,hemoglobin,serum iron,upper arm circumference,body mass index(BMI),deltoid skinfold,hs-CRP,T3,FT3,T4,FT4,TSH in MHD patients with mild,moderate and serve rate MIS were significant different(P ＜ 0.01).Of 54 MHD patients,32 cases were with micro inflammatory state,accounting for 59.26％ (32/54).There was a positive correlation between FT3 and albumin (P ＜0.01).T3 was related to serum creatinine(P ＜ 0.05).Thyroid function parameters showed a negative correlation with hs-CRP,MIS(P ＜ 0.01).And a negative correlation was seen between nutrition indices and hs-CRP and MIS (P ＜ 0.01).Conclusion Thyroid function can reflect the nutrition status of MHD patients to some degree,and both relate with miro-inflammation.Furthermore,MIS is a useful index for the estimation of malnutrition inflammation status.

Objective To observe the effect of Cordceps Sinensis (CS) on the expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in the kidney of spontaneously hypertensive rats(SHR), and to investigate the mechanism of CS. Methods Male SHRs (23 week old) were randomly divided into 4 groups: a group without any treatment (Group S), a group treated with Cordceps sinensis at 4 F), and a group received daily intragastric administration of CS at 4 male WKY rats were used as normals controls. At the end of 8 weeks, all rats were sacrificed. Serum creatinine(Scr), 24 h urinary protein count, and the expression of ICAM-1 and VCAM-1 were examined by immunohistochemical technique and RT-PCR. Results Compared with the WKY rats, blood pressure, 24 h urinary protein count, Scr,and the expression of ICAM-1 andVCAM-1 in the kidney of SHR significantly increased (P＜0.05).Compared with Group S, blood pressure decreased after treatment by fosinopril (P＜0.05). Compared with Group S, the levels of Scr, 24 h urinary protein count, and glomerular lesion were significantly reduced in the CS and/or fosinopril treatment group. The expression of ICAM-1 and VCAM-1 was significantly decreased in these groups (P＜0.05).Conclusion CS may play a role in the protection and anti-fibrosis in the process of renal injury in SHR through reducing the expression of ICAM-1 and VCAM-1.

Aim To investigate the effects of classic calcium antagonists verapamil(Ver),nifedipine(Nif),diltiazem(Dil)and the novel calcium antagonist N-n-butyl haloperidol iodide(F2)which was synthesized by our lab by regulating Ca2+-independent phospholipase A2(iPLA2)on hypoxia/reoxygenation(H/R)injury of cardiac microvascular endothelial cells(CMECs)and the mechanisms.Methods The CMECs were isolated from SD neonatal rats.The H/R model was established,then cells were treated with different concentrations of calcium antagonists and F2.The content of LDH in the cell supernatant was measured by colorimetric method.The levels of IL-6 and AA in cell supernatant were measured by ELISA;and late-stage apoptosis was measured by TUNEL.The mRNA and protein expression levels of iPLA2 in CMECs were examined by real time-PCR and Western blot analysis.Results Calcium antagonists except Dil decreased the generation of LDH,IL-6 and AA in a dose-dependent manner(P<0.05),and reduced the apoptosis(P<0.05).F2 and Ver decreased the mRNA and protein expression of iPLA2 in a dose-dependent manner,while there were no such effects for Nif and Dil.Conclusions Calcium antagonists except Dil have protective effects against H/R injury.F2 and Ver protect CMECs against H/R injury partly through iPLA2.

A valve-free continuous flow method and instrument were established,with only a multi-channel pump for delivering the sample and reagent,and without any injection or solenoid valves and sample loop for selecting and adding the sample or reagent.Nitrate was reduced to nitrite with Cu-Cd reductant column,and then detected with spectrophotometric detector.The proposed method was suitable for determination of nitrate at normal level in most of estuary and coastal seawaters.With the optimum parameters,the linear range and detection limit were 5-180 μmol/L and 0.27 μmol/L,respectively.The samples of 10 and 80 μmol/L nitrate were continually measured for 11 times,and the relative standard deviations were 1.4％ and 1.3％,respectively.The recovery of real samples at different salinity ranged between 99.4％ and 106.1％.There was no significant difference in the analytical results between the proposed method and the flow injection analysis (FIA).In comparison with FIA,the method and instrument were less cost and easy to operate,and was suitable to be applied in general laboratories and field for continuous monitoring.The method was successfully used to measure the nitrate in seawater samples in Xiamen's Western Harbor and monitor nitrate in Jiulongjiang estuary.

Aim To investigate the effect of N-n-butyl haloperidol iodide(F2) on mitochondria-dependent apoptotic pathway of H9c2 cardiac myocytes during hypoxia/reoxygenation(H/R) injury.Methods The H/R models of H9c2 cardiac myocytes were established.The H9c2 cardiac myocytes were randomly divided into five groups: control group(C group), hypoxia/reoxygenation group(H/R group), F2 low concentration group(L), F2 medium concentration group(M), F2 high concentration group(H).Apoptotic rate was evaluated by flow cytometry(FCM).The levels of Cyto C, Bcl-2, Bax were observed by Western blot.Caspase-3 activity was measured with colorimetry.Results Compared with H/R group, F2 low, medium and high concentrations group could significantly decrease apoptosis rate and increase the ratio of Bcl-2 to Bax proteins and inhibit the release of Cyto C into the cytosolic fraction, and decrease caspase-3 activity.Conclusion F2 can protect H9c2 cardiac myocytes against H/R-induced injury through interfering in mitochondria-dependent pathway.
