Objective To investigate the effects of dexmedetomidine on the outcome in rats with sepsis. Methods Male SD rats, aged 10-14 weeks, weighing 260-390 g, were used in this study. Sepsis was induced by cecal ligation and puncture (CLP). Ninety rats of successful sepsis model were randomly divided into 3 groups ( n = 30 each) : control group (group C), midasolam group (group M) and dexmedetomidine group (group D). In group C, M and D, normal saline at a rate of 1 ml/h, midazolam at a rate of 0.6 mg·kg-1·h-1 and dexmedetomidine at a rate of 5 μg·kg-1·h-1 were infused iv for 8 h after operation respectively. Ten rats of each group were selected for observation of the survival condition during 24 h after operation. Another 10 rats of each group were selected and blood samples were taken from carotid artery before operation and at 2, 4 and 5 h after operation for measurement of plasma concentrations of TNF-α and IL-6 by ELISA. The remaining 10 rats of each group were selected at 8 h after operation for determination of the renal function. The rats still alive after the determination of cytokines and renal function were killed and spleen tissues were taken for determination of the expression of caspase-3 and ubiquitin by Western blot. Results Compared with group C, the plasma concentration of TNF-α and fractional excretion of sodium (FENa+) were significantly decreased, caspase-3 expression in spleen tissues was down-regulated and abiquitin expression in spleen tissues was up-regulated in group M and D ( P < 0.05), while there were no significant differences in plasma concentration of IL-6 and creatinine clearance rate (Ccr) at 8 h after operation between group M and C and between group D and C ( P > 0.05). The plasma concentration of TNF-α was significantly lower in group D than in group M ( P < 0.05), while there were no significant differences in plasma concentration of IL-6, FE Na+ , Ccr and expression of caspase-3 and ubiquitin in splen tissues between group D and M ( P>0.05). The survival rates during 24 h after operation were 10%, 80% and 90% in group C, M and D respectively. The survival rates during 24 h after operation were signifrcantly higher in group M and D than in group C ( P > 0.05). Conclusion Dexmedetomidine can raise the survival rate during sepsis.

Objective To investigate the application and nursing care of bronchoalveolar lavage (BAL)by fiberoptic bronchoscopy in patients with mechanical ventilation. Methods 64 patients with mechanical ventilation in RICU were randomly divided into the control group and the observation group with 32 patients in each group. The patients in both groups were accepted anti-infection, atomization inhalation and other supportive treatments. The patients in the observation group were treated with BAL, and the patients in the control group accepted routine treatment. The therapeutic effects in the two groups were evaluated and compared. Results There was significant difference in the recovery rate and effective rate, the blood gas analysis compared with the control group was significantly improved, the time of pulmonary infection control window, mechanical ventilation, length of stay were shorter than the control group. The case number to remove ventilator successfully, organs failure and hospital mortality were less than the control group. Conclusions Fiberoptic bronchoscopy with BAL treatment could be safety and efficacy for patients with mechanical ventilation. Nursing intervention plays an important role and a good therapeutic effect for improving achievement ratio of BAL.

Objective To compare Th1/Th2 drift situation in patients with lymphoma with that in patients with solid tumors, and establish the effective immune function detectable criterion of lymphoma in biological treatment process. Methods The whole blood samples of 10 patients with lymphoma, 202 patients with solid tumors including 36 patients with upper digestive tract cancer, 64 colorectal cancer, 43 lung cancer and 20 the other malignancies, and 30 healthy persons as controls were collected. Stimulation agent was used to stimulate the cells in order to increase cell factor expression and fluorescent labeled specific anti-cytokine monoclonal antibody was used to bind with specific antigen. The expression of specific cytokines was detected by flow cytometry. Results Positive percentages of IFN- γ and IL-4 and ratio of IFN- γ /IL-4 in CD+4 T cells of human peripheral blood had statistically differences between in patients with lymphoma and controls (P < 0.05). The ratio of Thl/Th2 (CD+4 intracellular cytokine INF-α/IL-4) in patients with lymphoma was lower than that in patients with upper digestive tract cancers (esophagus and stomach cancers) (P = 0.023), however, had no statistical differences with that in patients with other solid tumors (colorectal, lung, kidney, breast and other tumors), but had a downward trend. Conclusion Immune functions in patients with lymphoma are lower than those in patients with solid tumors and immune treatment is a necessary to adjuvant chemotherapy. The ratio of Th1/Th2 (INF- α/IL-4) is expected to become effective detection criterion.

Objective To observe the therapeutic effect of treating primary dysmenorrhea with cold coagulation and blood stasis with warming-necdle. Methods 60 cases of primary dysmenorrhea with cold cougulation and blood stasis,which were treated during 2007 to 2008, were randomly divided into an acupuncture group and a medication group. The acupuncture group was treated with acupuncture at Ciliao and Sanyinjiao, while the medication group was treated with indomethacin. Results The total effective rate was 100% in the acupuncture group, and 93.3% in the medication group. The effects of the two groups were significantly different (P＜0.05). Conclusion Warming-needle is an effective therapy for primary dysmenorrhea with cold eougulation and blood stasis

Objective To detect the expression of serum soluble E?cadherin(sEC)before and after operation in breast cancer patients,and to ex?plore its clinical significance. Methods The levels of sEC in 42 patients with breast cancer and 18 patients with benign breast diseases were tested by enzyme?linked immunosorbent assay(ELISA)before and after operation as well as in 30 healthy controls. Its correlation with clinical and patho?logical characteristics was analyzed. Results The levels of sEC in breast cancer patients before operation were significantly higher than patients with benign breast diseases and controls,which declined significantly after operation. Moreover,the levels of sEC in those with high clinical grading and lymphatic metastasis were also higher than in the ones with low grading and negative lymphatic metastasis(P<0.05). Conclusion The levels of sEC in breast cancer patients before operation are specific and closely related with pathological grade and lymphatic metastasis,which may be a pre?dictive factor for prognosis of breast cancer.

Objective To investigate the role of anti-herpes ximplex virus (HSV)-1 IgM secreting cells detection assay in early diagnosis of herpes simplex encephalitis. Methods Twenty-three herpes simplex encephalitis cases and 40 control cases were included in this study. Anti-HSV-1 IgM secreting cells and anti-HSV-1 IgM were retrospectively tested in the patients' cerebrospinal fluid by enzyme-linked immunosorbent spot (ELISPOT) and enzyme-linked immunosorbent assay (ELISA), respectively. The data analysis was performed by using Fisher Exact Test. Results Using ELISPOT method for detection of 9 HSV-1 encephalitis patients' and 16 clinical control cases anti-HSV-1 IgM secreting cells within two weeks after disease onset, the sensitivity of ELISPOT for detecting anti HSV-1 IgM secreting cells in the cerebrospinal fluid was 88.9% (8/9) and the specificity was 93.8%(15/16). On the other hand, the sensitivity of ELISA for detecting anti-HSV-1 IgM in ccrebrospinal fluid was 16.6% (2/12) and the specificity was 88.2% (15/17) when using ELISA method for detection of 12 HSV-1 encephalitis patients' and 17 clinical control cases's anti-HSV-1 IgM secreting cells. The sensitivities of the two methods were statistically different (P<0.01). Conclusion Compared to ELISA, ELISPOT for detecting the anti-HSV-1 IgM secreting cells in cerehrospinal fluid is a more sensitive method for early diagnosing herpes simplex encephalitis.
