Objective To establish a method for detection of RhD(+) red blood cells mixed in D-negative blood by flow cytometry(FCM).Method RhD(+) and RhD(-) RBCs were mixed according to predefined ratios.Cells were indirectly labeled,with IgG anti-D labeled as the first antibody,and FITC-anti-IgG F(ab')2 as the second antibody.The percentage of RhD(+) RBCs was determined by FCM,and the best dosage of IgG anti-D was also defined.The ratio of red cells in the two groups,measured by FCM,was compared with the actual ratio.The consistency of method was also evaluated.Results The effective dosage of IgG anti-D was 1∶4,and 50?l/1?106 cells.When the actual percentages of RhD(+) cell among RhD(-) cells were 2.5%-0.312%,the correlation coefficient between the percentages measured by FCM and the actual percentages was 0.987.The same tubes,containing 10% and 2.5% RhD(+) RBCs,were each tested for 10 times,and their coefficient of variation were 3.4%,and 4.9%,respectively.Conclusion The method of quantifying the RhD(+) RBCs in D-negative blood by FCM is feasible and repeatable,which deserves a further clinical application.

Objective To investigate the induction mechanism of MT ⅢmRNA in the brain after cerebral ischemia.Methods The forebrain ischemia reperfusion model was established in rats. The changes of the expression of MT Ⅲ mRNA in hippocampus after forebrain ischemia reperfusion were observed by in situ hybridization method. The changes of free Zn 2+ in hippocampus after forebrain ischemia reperfusion was examined using Zn 2+ specific fluorescent probe(TSQ). The Zn 2+ chelator (CaEDTA) was injected into the lateral ventricles for determining influences of Zn 2+ on the MT Ⅲ mRNA expression and the neuronal damage after forebrain ischemia/reperfusion.Results (1) The expression of MT ⅢmRNA in hippocampus increased gradually after cerebral ischemia and reached the peak in 96 hours after reperfusion. Seven days after reperfusion the expression of MT ⅢmRNA reduced to the normal level. (2) Zn 2+ fluorescence in the hilus of dentate gyrus, CA 3 region and the stratum radiatum and stratum oriens of CA 1 decreased slightly at 48 hours after reperfusion. From 72 to 96 hours after reperfusion, the fluorescence returned to normal, but some new fluorescence dots appeared in pyramidal neurons of CA 1 and the hilus of dentate gyrus increased gradually. Seven days after reperfusion, the fluorescence returned to normal. (3) The cell membrane impermeable Zn 2+ chelator could reduce the intracellular concentration of free Zn 2+ and the expression of MT Ⅲ mRNA.Conclusion The expression of MT Ⅲ mRNA can be induced by the increase in the concentration of intracellular free Zn 2+ after forebrain ischemia/reperfusion.

Objective To observe the therapeutic effect of integrated traditional Chinese and western medicine treatment on systemic inflammatory response syndrome after trauma. Methods Totally 86 cases of severe trauma patients with systemic inflammatory response syndrome in ICU were randomly divided into control group and treatment group. The control group was given routine treatment of ulinastatin, and the treatment group was treated with Xuebijing injection 50 mL, intravenously injected twice per day and rhubarb powder 10 g through stomach tube twice per day for 5 days. The clinical effect and levels of inflammatory factors before and after treatment of the two groups were observed. Results During 5 days of treatment, the levels of TNF-α, IL-6 and IL-8 of the treatment group decreased continuously (P<0.05), while which of the control group increased continuously (P<0.05). CRP level of the two groups had no significant difference in the first day of treatment (P>0.05), but which of the treatment group was lower than the control group from the second day of treatment (P<0.05). The average hospital stay, ICU stay, 28 d mortality and APACHEⅡ score of the treatment group were better than that of the control group (P<0.05). Conclusion Xuebijing injection and rhubarb powder in addition to conventional treatment can relieve inflammatory response, effectively inhibit the generation and release of inflammatory mediators, improve the survival rate of systemic inflammatory response syndrome.

To explore the associations between the presence of bacteria and virus in the nasopharyngeal secretions, and wheezing, condition and hospitalization period in infants with community acquired pneumonia. Methods Clinical data, inclu-ding detection of bacteria and viruses, conditions and hospitalization period, of 1106 hospitalized infants with community ac-quired pneumonia from March 2009 to February 2010 were retrospectively analyzed. The infants were classiifed into wheezing (697 cases) and non-wheezing (409 cases) groups. Results Viruses were detected in 540 infants (48.8%), and the total detection rate of viruses and detection rate of respiratory syncytial virus in wheezing group were signiifcantly higher than those of non-wheezing group (P=0.000). Bacteria were detected in 590 cases (53.3%) and no signiifcance was found between two groups (P=0.821). The detection rate of Streptococcus pneumonia was higher in wheezing group than that of non-wheezing group (P=0.038). Comparing to the infants detected with both viruses and bacteria, no signiifcances were found in the occurrence of severe pneumonia and hos-pitalization period in those infants detected with viruses only (P>0.05), as well as in the wheezing time of period (P>0.05). Con-clusions Wheezing in infants with community acquired pneumonia is related to the infection of viruses, especially to respiratory syncytial viruses. Virus infection accompanying bacterial infection has no impact on duration of hospitalization and wheezing. The infection of Streptococcus pneumonia may relate to wheezing in infants.

In this paper, a detailed analysis was made on relevant literatures about bear bile powder in terms of chemical component, pharmacological effect and clinical efficacy, indicating bear bile powder's significant pharmacological effects and clinical application in treating various diseases. Due to the complex composition, bear bile powder is relatively toxic. Therefore, efforts shall be made to study bear bile powder's pharmacological effects, clinical application, chemical composition and toxic side-effects, with the aim to provide a scientific basis for widespread reasonable clinical application of bear bile powder.
