promoted by high glucose, which can enlarge the biological effect of PAF.

Objective To study the effect of high glucose and lysophosphatidylcholine (LPC) on the role of fibronectin and plate-let activating factor (PAF) via the interaction of endothelial cells and mesangial cells. Methods The model of intercellular interaction be-tween endothelial cells and mesangial cells was established and divided into 4 groups: control, mannitol, high glucose and LPC, and BN52021 group. The level of fibronectin and PAF were determined by enzyme linked immunosorbent assay in the culture media. Results The level of fibronectin and PAF of high glucose and LPC group were higher than those of control group in co-culture and monolayer cell cul-ture (P<0.05). Intervened by high glucose and LPC, the level of fibronectin and PAF of co-culture were higher than those from monolay-er cell culture (P<0.05). The level of fibrocentin in the BN52021 group was lower than that of high glucose and LPC (P<0.05). Con-clusions Exposed to high glucose and LPC, endothelial cells and mesangial cells can interact with each other to produce more fibrocentin and PAF. The increase of fibronectin is partly concerned with PAF.

Objective To study the effect of astragalus membranaceus on the interaction of mesangial cells and endothelial cells in the media of high glucose and lysophosphatidylcholine. Methods The model of intercellular interaction between endothelial cells and mesangial cells of diabetic nephropathy was established and divided into 4 groups:control, mannitol, high glucose and lysophosphatidylcholine, intervented with astragalus membranaceus. Endothelial cells and mesangial cells were co-cultured in DMEN with or without astragalus membranaceus in high glucose and lysophosphatidylcholine media up to 24 hours. The level of collagen Ⅳ and fibrocentin were determined by enzyme linked immunosorbent assay in the culture media. Results The level of collagen Ⅳ and fibrocentin of high glucose and lysophosphatidylcholine group was markedly higher than that of control group in co-culture and the ordinary monolayer cell culture (P

OBJECTIVETo study whether the dose of controlling antihypertensive drug is reduced by transcutaneous electrical acupoint stimulation (TEAS) and the anesthetics, as well as the control of blood pressure (BP) and heart rate (HR) in endoscopic endonasal surgery with general anesthesia.

METHODSSixty patients for selective endoscopic endonasal surgery with general anesthetics and controlling antihypertension involved were selected and randomized into a TEAS group, a sham-TEAS group, 30 cases in each one. The electric pads were attached to bilateral Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6) and Quchi (LI 11), stimulated with Hans-200 apparatus, 3 to 5 mA, 2 Hz/100 Hz in the TEAS group based on the patients' response to comfort. No electric stimulation was applied to the sham-TEAS group. The general anesthesia started after 30 min intervention and lasted till the end of surgery. The BP and HR were observed and recorded at the end of monitoring in operation room, 10 min after tranquilization (T0), 30 min after intervention (Tj, after induction~of general anestiesa (T2), 30 min after surgery start (T3), 60 min after surgery start (T4) and 30 min after extubation (T5). The doses of vecuronium bromide, propofol and nitroglycerin were recorded statistically in surgery, as well as the operative bleeding volume, the operative time, the resuscitation time and the visual analogue scale (VAS) score after resuscitation.

RESULTSCompared with that at T0, the mean arterial pressure (MAP) at T2, T3, T4 and T5 in the TEAS group and at T3 and T4 in the sham-TEAS group was all reduced, indicating the significant difference (all P < 0.01). MAP at T2 and T5 in the TEAS group was lower than that in the sham-TEAS group (both P < 0.01). Compared, with that at T5, except at T2 in the TEAS group (P<0. 05), HR was not different significantly at the rest time points (all P > 0.05). HR was different at T2 to Ts in the sham-TEAS group statistically (all P < 0.01). The doses of vecuronium bromide, propofol and nitroglycerin, the operative bleeding volume, the operative time, the resuscitation time and VAS after resuscitation were not different significantly between the two groups (all P > 0.05).

CONCLUSIONThe general anesthesia with TEAS and anesthetics involved for controlling antihypertension contributes to the control of BP and HR in the patients in endoscopic endonasal surgery. The impacts are not obvious on the doses of antihypertensive drug, the general anesthetics, the operative bleeding volume, the time of resuscitation and the postoperative analgesia.

Objective To evaluate the effect of dexmedetomidine on the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) during focal cerebral ischemia-reperfusion (I/R) in rats.Methods Thirty pathogen-free male Sprague-Dawley rats,aged 12-16 months,weighing 300-360 g,were randomly divided into 3 groups (n =10 each) using a random number table:sham operation group (group Sham),focal cerebral I/R group (group I/R),and dexmedetomidine group (group D).Focal cerebral I/R was induced by occlusion of the right middle cerebral artery.In group D,dexmedetomidine was given as a loading dose of 1 μg/kg (over 10 min) starting from 1 h of ischemia,followed by an infusion of 0.05 μg · kg-1 · h-1 until 2 h of reperfusion.Neurological deficit was assessed and scored at 24 h of reperfusion,and then the rats were sacrificed.Brains were removed for determination of cerebral infarct size and expression of iNOS and COX-2 in the hippocampus (by Western blot).The percentage of cerebral infarct size was calculated.Results Compared with group Sham,the neurological deficit score,percentage of head swing to the left,percentage of cerebral infarct size,and expression of iNOS and COX-2 in the hippocampus were significantly increased in I/R and D groups (P＜0.05).Compared with group I/R,the neurological deficit score,percentage of head swing to the left,percentage of cerebral infarct size,and expression of iNOS and COX-2 in the hippocampus were significantly decreased in group D (P＜0.05).Conclusion The mechanism by which dexmedetomidine mitigates focal cerebral I/R injury may be related to inhibition of iNOS and COX-2 expression in rats.

With the public hospitals expanding,the nurses at age of marriage or bearing are enrolled and account for large part of all health care workers in China.A significant percentage of nurses in the period of pregnancy or lactation,especially abortion and sterility,deteriorate the shortage of nursing human resources and the nurses' health.It is essential to cope with the matter in order to maintain the nurses and contribute to the professional development.In this paper,we review the human resource management of the nurses during the periods at home and abroad from the human resources,occupational protection and management approaches,which is contributed to supplement the human resource.

45 cases of childhood extrinsic asthma (CEA) were divided into the treatment group with carboxymethykited starch (CMS) (n=30) and the control group (n=15). The total effective rate of the former was 63% (P

Objecfive To investigate the change of V-ATPase B subunits on epithelial to mesenchymal transition (EMT)in rat renal tubular epithelial cells (NRK52E) stimulated by transforming growth factor β1 (TGF-β1). Methods NRK52E cells were stimulated by TGF-β1 (10 μg/L)for O h(control),12 h,24 h,48 h,72 h after sefrum-free culture for 24 h.The mRNA and protein expression of E-cadherin,α-SMA,B2 and B1 subunits of V-ATPase were detected by real-time PCR,Western blotting and immunofluorescence. Results After stimulated by TGF-β1 (10 μg/L)for 48 h,the expression of α-SMA was markedly increased(P<0.05),but the expression of E-cadherin was dramatically decreased(P<0.05).Meanwhile,the expressions of V-ATPase subunit B2 was significantly increased (P<0.05).However,the B1 subunit distributed rarely in NRK 52E cells,and did not increase after TGF-β1 stimulation.Double-label immunofluoerscence staining also showed that the V-ATPase B2 subunit was increased in the cytosol.tending to accumulate to the cell membrane after TGF-β1 stimulation. Conclusions The main isoform of V-ATPase distributed in NRK52E cells is B2 subunit.B2 subunit is increased alone with TGF-β1-induced EMT.It may suggest that V-ATPase B2 subunit may play a potential role in TGF-β1-induced tubular EMT and renal fibrosis.

Objective To explore the difference between interval storage and continuous storage of dynamic imagines in contrast enhanced ultrasound (CEUS) quantitative analysis. Methods Two CEUS were performed for each of fifteen participants using interval storage and continuous storage of dynamic images. A number of parameters were analyzed including rising time (RT), time to peak (TTP), mean transit time (MTT), maximum intensity (IMAX), and area under the curve (AUC). The disk usage and time consumpation were also compared for analysis. Results There were no differences in RT, TTP, MTT, IMAX, AUC between the two groups (t=1.028, 1.012, 0.558, 0.223, 0.556, P=0.322, 0.329, 0.586, 0.826, 0.587). There was significantly positive correlations between them (r=0.989, 0.992, 0.867, 0.865, 0.947, all P<0.05). The disk usage in interval storage group was about 1/3 of that in contiunous storage group. And the interval storage method could saved 25-30 min in each case. Conclusion Interval storage is worthy for further clinical application on the groud of its disk usage sparing and less time consumpation without compromising the image quality for analysis.
