Objective To investigate the distribution of rick factors between intracerebral hemorrhage(ICH) and coronary heart disease (CHD) in Tongliao city in Innermogolia. Methods Medical records(departments of medical neurology and cardiovascular internal medicine in 2003~2005) were randomly selected from 6 general hospitals above the second class in Tongliao city Innermogolia .All the risk factors of the cartain diseases were carryed on retrospective investigation analysis. Results All the survey index have significantly statistical difference in the basic data. Single-factor non-conditional Logistic regression analysis showed 10 risk factors including the gender, age, nation, smoking, hypertension, history of hypertension, alcohol drinking, glucose(GLU), history of diabetes and triglyceride(TG) have significantly statistical difference. These 10 risk factors were taken into multifactor stepwise regression model. 8 risk factors( gender, age, smoking, history of hypertension, history of diabetes,GLU,TG and hypertension) had significantly statistical difference. Conclusions Compared with CHD, the influence of age, smoking, history of diabetes and TG are lower, and the influence of the gender, the history of hypertension, GLU and hypertension are higher in ICH.

AIM: To investigate the effect of pyrrolidine dithiocarbamate (PDTC), a specific inhibitor of NF-κB on the proliferation and apoptosis of K562 cells and to explore the anti-tumor mechanism of PDTC.METHODS: Trans AM~(TM) NF-κB p65 kit was used to detect the activity of p65 in K562 cells treated by PDTC. The effect of PDTC on the proliferation of K562 cells was measured by WST-1 method. DNA damage was detected by single cell gel electrophoresis (comet assay). The procaspase-3 and activated protein level of caspase-3 were detected by Western blotting.RESULTS: The activity of p65 in K562 cells was inhibited after treated by PDTC (P<0.01). Simultaneously the cell proliferation was significantly inhibited in a dose-and time-dependent manner (P<0.01). The degree of DNA damage in K562 cells treated with PDTC at concentrations of 25 μmol/L, 50 μmol/L or 100 μmol/L was more severe than that in control. The rates of comet cells in the PDTC-treated groups (43.50%, 84.00%, 95.63%) were significantly higher than those in control (9.75%, P<0.01), and it was also dose-dependent. The expression of procaspase-3 and activated caspase-3 protein were detected in the cytoplasm of the K562 cells treated by PDTC by Western blotting.CONCLUSION: NF-κB plays an important role in regulating cell proliferation and apoptosis in K562 cells. PDTC inhibits NF-κB activity and elevates the expression of caspase-3, which is related to increase in cell apoptosis.

OBJECTIVE To realize the present resistance characteristics of enterococci to common antimicrobial agents,and to provide reference for clinical therapy. METHODS A total of 79 isolates of enterococci were collected from samples during the period of 2000-2003.The broth microdilution test and ?-lactamase determination were performed for each of the strains.The laboratory data were analyzed. RESULTS The rates of Enterococcus faecalis and E.faecium were 73.4%,and 26.6% of all enterococci isolates.The most common sites of infection were urinary tract(35.4%),surgical secretion(24.1%),and sputum(15.2%).The rate of E.faecium approached 50% of enterococci in urinary tract.The antibiotic resistance of E.faecium was more than E.faecalis to ampicillin,penicillin,and rifampin.The ratio of HLAR enterococci and VRE to total enterococci isolates were 61.9% and 0;?-lactamase producing rate was 6.3%. CONCLUSIONS Urinary infection caused by enterococci is most frequent.E.faecium is found more easily in urinary tract than in the others and very resistant to antibiotics.Vancomycin shows fairly high activity against enterococci.The different regimens should be adopted for different enterococci.

ObjectiveTo investigate the disruption of blood-brain barrier (BBB) after brain trauma in rats using IgG immunohistochemical staining.MethodsAn impact-acceleration head injury model was established with rats. Histological changes of rats' brains were observed by HE staining and light and electron microscopes at 1 h, 6 h, 24 h and 7 d after injury, and BBB permeability was analyzed semi-quantitatively by IgG immunohistochemical staining at the same time points.ResultsThe spot bleeding and brain edema was present in the damage region after brain trauma and endothelial cell damage and astrocyte swelling could be found under electron microscope. The extravasations of IgG was detected in the injured hemisphere of rats at 1 h, and achieved the peak at 6 h, remained a high level up to 24 h, and decreased at 7th d.ConclusionThe disruption of BBB function occurs after brain trauma in rats, and detection of IgG extravasations tested by immunohistochemical staining is a simple and sensitive way to investigate BBB permeability.

Objective To investigate the effect of human umbilical cord mesenchymal stem cells (UC-MSCs) on immune cells and inflammatory factors in septic rats.Methods 184 male Sprague-Dawley (SD) rats were divided into normal control group (n = 8), sham operation group (n = 48), sepsis model group (n = 64), and UC-MSCs treatment group (n = 64). An animal model of sepsis was produced by cecal ligation and puncture (CLP). In the UC-MSCs treatment group 1 mL UC-MSCs (2×106/mL) were injected intraperitoneally at 1 hour after the model establishment;the sham operation group and the sepsis model group were given the same amount of saline. Sixteen animals in each group of the sham operation group, sepsis model group, and UC-MSCs treatment group were observed for 72-hour survival rate. The percentages of CD4+ T cells and the ratio of helper T cells 1/2 (Th1/Th2) in whole blood cells were measured by flow cytometry at 12, 24, 48 and 72 hours after operation. The levels of tumor necrosis factor-α (TNF-α), high mobility group box 1 (HMGB1), interleukin-10 (IL-10) were measured by enzyme linked immunoabsorbent assay (ELISA).Results The 72-hour survival rate of the UC-MSCs treatment group was slightly higher than that of the sepsis model group [62.5% (10/16) vs. 50.0% (8/16),χ2 = 0.509,P > 0.05]. The percentage of CD4+ T cells and Th1/Th2 ratio in the sepsis model group were significantly higher than those in the sham operation group at 12 hours after operation, and decreased as the time prolonged to 48 hours. The levels of plasma inflammatory factors were significantly higher than those of sham operation group at 12 hours after operation, TNF-α and IL-10 were decreased at 48 hours after operation, while HMGB1 continued to increase until 72 hours after operation. Compared with those in the sepsis model group, the percentages of CD4+ T cells at 12 hours and 24 hours after operation [(49.66±0.91)% vs. (59.11±1.17)%, (41.80±0.89)% vs. (49.84±0.99)%], the levels of Th1/Th2 ratio at 12, 24, 48 hours after operation (0.745±0.065 vs. 1.254±0.115, 0.407±0.077 vs. 0.806±0.061, 0.280±0.057 vs. 0.454±0.049), and the levels of TNF-α and HMGB1 were significantly reduced at 12, 24, 48 and 72 hours after operation in the UC-MSCs treatment group [TNF-α(ng/L):52.60±6.60 vs. 58.03±6.53, 71.77±8.48 vs. 147.39±11.37, 111.83±10.76 vs. 271.36±19.04, 83.09±7.43 vs. 171.04±14.06; HMGB1 (ng/L): 149.12±9.89 vs. 187.33±12.79, 192.94±14.92 vs. 442.35±52.72, 1393.67±88.86 vs. 1950.90±126.66, 1875.84±111.67 vs. 2557.12±186.01], all with statistically significant differences (allP <0.05). The level of IL-10 was significantly higher at 12, 24, 48 and 72 hours after operation (ng/L: 65.46±5.51 vs. 33.32±4.17, 86.49±5.78 vs. 63.11±5.53, 142.73±9.94 vs. 106.81±6.36, 123.74±10.90 vs. 89.90±7.71, allP <0.01).Conclusion UC-MSCs can make CD4+ T cells in early sepsis, and Th1/Th2 ratio to normal, by reducing the levels of proinflammatory factors, and increasing the level of anti-inflammatory factor, and improve sepsis immune function status, but cannot improve the survival rate of animals.
