Objective To evaluate the role of phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2) in 17β estradiol-induced inhibition of propofol-caused neuroapoptosis in the hippocampus of newborn rats.Methods Seventy-eight male Sprague-Dawley rats,aged 7 days,weighing ll-18 g,were divided into 6 groups (n =13 each) using a random number table:dimethyl sulfoxide (DMSO) group,fat emulsion group (group F),17β estradiol group (group E),propofol group (group P),propofol plus 17β estradiol group (group PE) and propofol plusl7β estradiol plus mitogen-activated protein kinase kinase 1/2 inhibitor U0126 group (group PEU).17β estradiol 600 μg/kg was injected subcutaneously every 24 h for 7 consecutive days in group E,and the equal volume of DMSO was given instead in group DMSO.Propofol 75 mg/kg was injected intraperitoneally every 24 h for 7 consecutive days in group P,and the equal volume of fat emulsion was injected instead in group F.Propofol 75 mg/kg was injected intraperitoneally,and 17β estradiol 600 μg/kg was injected subcutaneously every 24 h for 7 consecutive days in group PE.Propofol 75 mg/kg was injected intraperitoneally,17β estradiol 600 μg/kg was injected subcutaneously,and U0126 10 mg/kg was injected intraperitoneally every 24 h for 7 consecutive days in group PEU.At 15 min after the last injection,3 rats in each group were randomly selected,and arterial blood samples from the cardiac apex were collected for determination of arterial oxygen partial pressure.The animals were sacrificed at 24 h after the last injection for determination of the expression of activated caspase-3 (by immunohistochemistry) and p-ERK1/2 (by Western blot).Results There was no significant difference in arterial oxygen partial pressure between the six groups (P＞0.05).Compared with group F,the expression of activated caspase-3 was significantly up-regulated,and the expression of p-ERK1/2 was downregulated in group P (P＜0.05).Compared with group P,the expression of activated caspase-3 was significantly down-regulated,and the expression of p-ERK1/2 was up-regulated in group PE (P＜0.05).Compared with group PE,the expression of activated caspase-3 was significantly up-regulated,and the expression of p-ERK1/2 was down-regulated in group PEU (P＜0.05).Conclusion The mechanism by which 17β estradiol inhibits propofol-caused neuroapoptosis in the hippocampus is related to up-regulation of the expression of p-ERK1/2 in newborn rats.

Objective To evaluate the effect of TBL (team-based learning) method in pharmacology teaching for the foreign students of clinical medicine. Methods In the course of pharmacology teaching of the foreign students of clinical medicine, TBL method was performed in the 2012-year students and tradi-tional teaching method was performed in the 2011-year students. After the teaching, students' grades in the ordinary performance, their final exam scores and their evaluation of the two teaching methods were com-pared. Graph pad 5 was used to analyze the data and the t test was performed. Results The average ordi-nary performance of the students with TBL was significantly higher than that with the traditional teaching [(84.94 ±12.66) vs. (72.30 ±4.90), P=0.000] and the final examination scores were significantly im-proved [(74.00±6.76) vs. (69.00±6.20), P=0.023]. The survey showed students were more satisfied with the TBL teaching mode than traditional teaching mode [(8.40±0.71) vs. (7.12±1.07), P=0.000]. Conclusion TBL teach-ing mode can effectively improve the pharmacology teaching effect of foreign students.

Aim To investigate effects of indole-3-carbinol (I3C) on hepatic stellate cells (HSCs) activated by acetaldehyde in precision-cut liver slices (PCLS). Methods PCLS were incubated with 700 ?mol?L-1 acetaldehyde and 200 ~ 800 ?mol?L-1 I3C for 6 h. The expression of ?-smooth muscle actin(?-SMA) in liver slices was analyzed by immunohistochemistry. The leakages of glutathione S-transferase (GST), lactate dehydrogenase (LDH) and content of transforming growth factor-?1 (TGF-?1) in media were assayed. Contents of malondialdehyde (MDA) and hydroxyproline (Hyp) in tissue were also determined. Expressions of matrix metalloproteinases-1 (MMP-1) and tissue inhibitor of metalloproteinase (TIMP-1) in media were analyzed by the western blot. Results The increase of activated HSCs due to acetaldehyde was inhibited by I3C (200~800 ?mol?L-1). Meanwhile, I3C treatment (200~800 ?mol?L-1) showed significant and concentration-dependent antagonistic actions on the increment of GST, LDH leakages into the media and MDA, Hyp contents in tissues induced by acetaldehyde. The increase of TGF-?1 was also remarkable inversed by I3C (200~800 ?mol?L-1). As compared with acetaldehyde group, the ratio of MMP-1/TIMP-1 was increased significantly by I3C treatment (800 ?mol?L-1)(P

Objective To apply the hydrocolloid dressings and hydrocolloid dressings combined GreenCream Dressing for central venous catheterization fixing, and to explore the effect of hydrocolloid dressings combined GreenCream Dressing in the prevention of venous catheter bacterial colonization and bacterial infection. Methods 470 patients who underwent the Inferior vena cava catheter were divided into 230 patients in the control group and 240 patients in the experimental group. The control group was fixed with hydrocolloid dressings after central venous catheter, and the experimental group was fixed with hydrocolloid dressings combined GreenCream Dressing after central vein catheter. The measurements included catheter bacterial colonization, catheter-related infections (CRIs) and catheter related blood stream infections (CR-BSIs), pathogenic bacteria colonization of the skin. At the same time, the skin safety was also confirmed. Results In the control group, 230 cases were retained for 1 419 catheter-days, and 240 cases in the experimental group were retained for 1 675 catheter-days. Compared with hydrocolloid dressings, hydrocolloid dressing combined GreenCream Dressing could reduce the incidence of CRIs from 1.8‰(3/1 675) to 0.7‰(1/1 675), and CR-BSIs from 2.4‰(4/1 675) to 0.7‰(1/1 675) respectively, with the statistically significant (χ2=6.39, 95%CI 1.30-31.41, andχ2=6.21, 95%CI 1.56-40.82;P<0.05). The results of bacterial colonization, CRIs and CR-BSIs showed that the most common bacteria were Staphylococcus and fungi. At the same time, compared with the hydrocolloid dressing, hydrocolloid dressing combined GreenCream dressing could reduce the incidence of skin pathogenic bacteria colonization, from 41.74%(96/230) to 28.33%(68/230),with the statistically significant (χ2=9.29,P=0.00);There was no difference between the two groups in the field of the incidence of abnormal skin manifestation (χ2=1.23, P=0.30), showing a good safety. Conclusions Hydrocolloid dressing combined GreenCream Dressing would be more effective to prevent bacterial colonization and bacterial infection of central venous catheter in department of neurosurgery.

Objective To evaluate the effect of 17β estradiol pretreatment on inflammatory responses during propofol-induced apoptosis in hippocampal nerve cells of developing rats.Methods Thirty-nine pathogen-free healthy male Sprague-Dawley rats,aged 7 days,weighing 11-18 g,were divided into 3 groups (n =13 each) using a random number table:fat emulsion group (group F),propofol group (group P) and propofol plus 17β estradiol group (group P+E).Propofol 75 mg/kg was intraperitoneally injected once every 24 h for 7 consecutive days in group P,and the equal volume of fat emulsion was given instead in group F.In group P+E,17β estradiol 600 μg/kg was subcutaneously injected,and 30 min later propofol 75 mg/kg was intraperitoneally injected once every 24 h for 7 consecutive days.The rats were sacrificed at 24 h after the last injection,the brains were removed and hippocampi were isolated for determination of activated caspase-3 expression (using Western blot) and interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) contents (by enzyme-linked immunosorbent assay).Results The levels of activated caspase-3,IL-1β and TNF-α in hippocampi were significantly higher in group P than in group F (P＜ 0.05).The levels of activated caspase-3,IL-1β and TNF-α in hippocampi were significantly lower in group P+E than in group P (P＜0.05).Conclusion The mechanism by which 17β estradiol pretreatment inhibits propofol-induced apoptosis in hippocampal nerve cells is related to inhibition of inflammatory responses of developing rats.

Objective To study the clinical value of magnetically controlled capsule endoscopy in diseases screening. Method We retrospectively analyzed 61 cases which were evaluated by magnetically controlled capsule endoscopy from March 2015 to December 2016. The items include operating time, the divergence rate score and cleanliness score of stomach. The consistency was compared between magnetically controlled capsule endoscopy and gastric duodenal endoscopy. Results 61 upper gastrointestinal tract studies were included. The mean age was (49.4 ± 11.6) years. No capsule retention, perforation or bleeding occurred. There was 98.4% patients, which cleanliness of stomach was good. There was 68.9% patients, which filling degree of stomach was good. The concordance rate of the two tests of gastrduodenoscopy and magnetically controlled capsule endoscopy was 89.9% (80/89). The concordance rate of the two tests was 78.9% (15/19) in esophageal and cardia, 92.9% (52/56) in stomach, 92.9% (13/14) in duodenum. Conclusion Our experience shows that magnetically controlled capsule endoscopy is a safe and useful tool for the diagnosis of upper gastrointestinal tract disease. The detection rate is similar to gastrduodenoscopy.
