Chinese Journal of Practical Nursing 2017;33(4):254-258
Objective To explore the effect of process quality monitoring for hospital infection control of ICU. Methods A total of 265 critically ill patients admitted to ICU were chosen as the control group from April 1, 2014 to March 31, 2015, who were strictly enforced three cluster strategies to prevent catheter related blood stream infection (CRBSI), catheter-associated urinary tract infection (CAUTI) and ventilator–associated pneumonia (VAP) with periodical data monitoring in ICU. Another 292 critically ill patients admitted to ICU were chosen as the observation group from April 1, 2015 to March 31,2016, who were added 3 measures of process quality monitoring on the basis of implementation method of the control group. The incidence of CRBSI, CAUTI and VAP time were compared between two groups. Results There was statistically significant difference on the incidence rate of the CRBSI between the two groups (χ2=4.504, P=0.034), which was respectively 1.79%(5/280) and 5.10%(13/255). There was statistically significant difference in the incidence rate of CAUTI between the two groups (χ2=5.708, P=0.017), which was respectively 3.48% (10/287) and 8.27% (21/254). There was statistically significant difference on the incidence rate of VAP between the two groups (χ2=8.291, P=0.004), which was respectively 3.48% (10/287) and 8.27% (21/254). Mean time of mechanical ventilation in the observation group and the control group was respectively (2.14±1.40) days and (3.37±2.01) days, there was no significant difference (P=0.073). Mean time of ICU stay in the observation group and the control group was respectively (6.04±1.04) days and (11.92±1.90) days, there was statistical significance (t=-1.840, P=0.024). Number of qualified central venous catheter maintenance, perineum clean and oral care had negative relevance with number of patients with CRBSI, CAUTI and VAP, correlation coefficient in the observation group was respectively-0.701,-0.618,-0.677, there was statistical significance (P<0.05). Conclusions The implementation of quality monitoring can reduce the number of patients with CRBSI, CAUTI and VAP, which suggests wide application in ICU.

Tianjin Medical Journal 2016;44(5):598-601
Objective To investigate the effects and mechanisms of bone marrow mesenchymal stem cells (BMSCs) on pancreatic fibrosis in rats of chronic pancreatitis. Methods Thirty healthy male SD rats were randomly divided into three groups:control group, model group and transplanted group (n=10 for each group). Chronic pancratitis rat model was induced by retrograde injection of oleic acid into the biliopancreatic duct. The sham operation group was treated only with solvent. Transplanted group was given BMSCs through caudal vein injection at 1 week and 5 weeks after the model induction. All rats were weighed at 1 week, 4 weeks and 8 weeks in three groups. After 8-week feeding,pancreatic tissues were harvested for HE and picric-sirius staining. The contents of transforming growth factorβ1 (TGF-β1), typeⅠcollagen and typeⅢcollagen were detcted by using ELISA. Results Compared with the control group, the weights of rats were decreased at 4 weeks and 8 weeks in model group and transplantated group (P<0.05). There were no significant differences in body weights between model group and transplantated group (P>0.05). The pancreatic fibrosis score and pathological injury were ameliorated signicantly in transplanted group. The contents of TGF-β1, typeⅠcollagen and typeⅢcollagen in pancreas were increased in model group than those of control group and transplanted group (P<0.05). Conclusion BMSCs transplantation can reduce the collagen secretion and reduce the degree of pancreatic fibrosis in rats with chronic pancreatitis, which may be related to the inhibition of the release of TGF-β1.

Objective To examine the expression and clinical significance of E26 transformation specific-1 in premature rupture of fetal membranes. Methods Fetal membranes from 75 women in the following categories were analyzed for Ets-1 expression: preterm and term premature rupture of fetal membranes; 70 women (control group) with term cesarean sections and without complications. Ets-1 protein was localized with the use of immunohistochemical S-P method. Results Ets-1 protein was expressed in both the nucleus and cytoplasm of trophoblast of human fetal membranes, with more obvious expression in the nucleus. Ets-1 protein's expression was up-regulated in the trophoblast of fetal membranes with premature rupture, which differed significantly from the control group (P<0.05). Ets-1 protein's expression was up-regulated in the trophoblast of fetal membranes with preterm premature rupture, which did not differ significantly from the control group (P>0.05). Conclusion Ets-1 is expressed in human fetal membranes and its expression is up-regulated with premature rupture of fetal membranes, suggesting a role for Ets-1 in extracellular matrix remodeling of the membranes. This study provides an evidence to predict premature rupture of fetal membrances.

To explore the anti-atherosclerotic mechanism of estrogen and especially observe the effect of estradiol on the content of cholesterol in J774a.1 mouse mononuclear/macrophage-derived foam cells which were incubated with oxidized low-density lipoproteins (ox-LDL). J774a.1 mouse mononuclear/macrophages were incubated with ox-LDL or with both ox-LDL and estradiol (1, 0.1 or 0.01 micromol x L(-1)). Oil red O staining was used to observe the formation of foam cells, and cholesterol oxidase fluorometric was used to determine the content of cellular cholesterol content. Western blotting and RTFQ-PCR were used to observe the expressions of scavenger receptor class B type I (SR-B I ) in J774a.1 foam cells. Compared with the control cells, J774a.1 mouse mononuclear/macrophage-derived foam cells showed significantly increased contents of total cholesterol and cholesterol ester (P < 0.001) and decreased SR-B I mRNA expression (P < 0.01). Estradiol treatment significantly lowered the contents of total cholesterol and cholesterol ester (P < 0.05), and increased SR-B I protein and mRNA expression (P < 0.01) in the foam cells in a dose-dependent manner. Estradiol can inhibit the formation of mononuclear/macrophage-derived foam cells by decreasing the contents of total cholesterol and cholesterol ester and up-regulating the expression of SR-B I in the foam cells.

Objective To investigate the expression of Notch4 protein and to analyze its correlation with the clinical parameters and the microvessel dentisty in renal cell carcinoma. Methods The expression of Notch4 was examined in 60 cases of renal cell carcinoma and the para-carcinoma tissue by SP immunohistochemical stain-ing ,and CD34 detection was used for counting microvessel density. Statistical analysis was performed to reveal the correlation with clinicopathological parameters ,microvessel density and prognosis. Results The positive rate of Notch4 protein expression was 75%(45/60)in para-carcinoma tissue,and was 43.3%(26/60)in renal cell car-cinoma,with significant difference on tumor grade and Lymph node metastasis(P<0.05). The microvessel densi-ty in Notch4 positive tissues was significant lower than that in the negative samples(P<0.05). The survival time of patients with Notch4 positive expression was significantly longer than that of patients with Notch4 negative expres-sion(P<0.05). Conclusion Notch4 protein plays an important role in the development of renal cell carcinoma. Notch4 expression might both attenuate the malignant biological characteristics and suppress the angiogenesis dur-ing tumor development.

Objective To explore the effect of modified Zexie Decoction on renal aquaporin-2 (AQP2) expression in high-salt hypertensive rat. Methods Hypertensive rats model was established by feeding rat with 8%high salt. Rats (n=50) were divided into model group, modern medicine group, traditional Chinese medicine groups of high, medium, low dose, with 10 rats in each group. The other 10 rats were fed with ordinary diet as normal group. Rats in traditional Chinese medi?cine of high, medium, low groups were given Zexie Decoction suspension of 16.2, 10.8 and 5.4 g/(kg·d) respectively;Rats in modern medicine group was given Valsartan hydrochlorothiazide 16.65 mg/(kg·d);the model group and normal group was ad?ministered with equal volume of distilled water. Animals were feed with medications at 1 mL/100 g by gavage for 4 weeks. On the 1st , 4th , 7th , 14th and, 28th day of administration, we measured SBP and collected 24 h urine. We employed immunohis?tochemistry to detect renal AQP-2 protein expression level and RT-PCR to detect renal AQP-2 mRNA transcription level. Results The rank of SBP from high to low is:model group>traditional Chinese medicine medium and low dose groups>traditional Chinese medicine high dose group and western medicine group>normal group. The rank of urine volume from high to low is:Western medicine group and traditional Chinese medicine high dose group>traditional Chinese medicine me?dium and low dose group > normal group, the difference was not statistically significant between traditional Chinese medi?cine medium and low dose group , or between western medicine group and traditional Chinese medicine high dose group. The renal AQP-2 in epithelial cells along the collecting duct wall of rats in model group show brown particles which are darker and wider distributed than those in normal group and traditional Chinese medicine of high, medium, low dose groups. RT-PCR results show that AQP-2 mRNA expression is highest in rats of model group and lowest in rats of traditional Chi?nese medicine high dose group (P<0.05). No statistical significance of AQP mRNA level was found between traditional Chi?nese medicine low group and model group (P < 0.05). Conclusion Modified Zexie Decoction can lower blood pres?sure by inhibiting the expression of AQP-2.
