0 05). For the average blood loss at 2 hour postpartum, it was 129 7 ml, 133 9 ml, 168 5 ml and 178 2 ml for group Ⅰ, Ⅱ, Ⅲ and Ⅳ respectively, while the total blood loss for the 4 groups was 243 3 ml, 242 9 ml, 308 1 ml, and 314 8 ml respectively. The average blood loss of group Ⅰ and Ⅱ was significantly less than group Ⅲ and Ⅳ ( P 0 05). The occurrences of postpartum hemorrhage (blood lose ≥400 ml) were 6 4%, 13 3%, 20 7% and 25 3% for group Ⅰ, Ⅱ, Ⅲ and Ⅳ respectively. There was no major adverse effects appeared. Conclusions Transamin is efficient and safe in reducing the postpartum blood loss. 1 0 g of Transamin has the best efficacy, and 0.5g of Transamin followed.

Objective The study consisted of two parts: in part Ⅰ the effects of propofol or/and procaine on CD18, CD62L expression and superoxide anion (SOA) release of phorbol 12-myristal 13-acetate(PMA) stimulated human neutrophils (PMNs) were studied in vitro; in part Ⅱ the effects of propofol or/and procaine on IL-6 and TNF-?production in endotoxin-stimulated human whole blood were studied. Methods PMNs were separated from the whole blood obtained from healthy 20-40yr old subjects. Part Ⅰ consisted of 9 groups: in group 1 (control) phosphate buffer solution was added to PMNs; in group 2 PMNs were stimulated by PMA 100mg?ml-1 ; in group 3-5 different concentrations of propofol (0.4, 4.0,40?g?ml-1) were added to PMA stimulated PMNs; in group 6-8 different concentrations of procaine (1.5,15,150?g?ml-1 ) were added to PMA stimulated PMNs; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to PMA stimulated PMNs. Part II also consisted of 9 groups: in groupl whole blood was mixed with normal saline; in group2 lipopolysaccharide (LPS) l?g?ml-1 was added to whole blood; in group 3-5 different concentrations of propofol (0.4,4.0,40?g?ml-1) were added to LPS stimulated whole blood; in group 6-8 different concentrations of procaine (1.5, 15, 150?g?ml-1 ) were added to LPS stimulated whole blood; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to LPS stimulated whole blood. CD18, CD62L expressions were measured by flow cytometry. SOA release was determined by cytochrome C reduction in the presence or absence of superoxide dismutase (SOD) . IL-6 and TNF-? production were measured by using radioimmunoassay. Results Propofol or/and procaine depressed CD18 up-regulation, CD62L shedding and SOA release of PMA-stimulated PMNs and propofol was more effective than procaine. Propofol enhanced but procaine inhibited the increased production of TNF-? and IL-6 in the LPS stimulated whole blood but when propofol and procaine were used in combination. The effectof procaine predominated. Conclusions Propofol or/and procaine can attenuate tissue damage induced by neutrophils by inhibiting the function of neutrophils.

Objective To know the influence of comfortable nursing for paitnets with malignant tumor on promoting their quality of life. Methods Selected 995 patients with malignant tumor who had diagnosed by pathology and coured by chemotherapy or radioehemotherapy. Divided them into the experimental group (498 cases) and the control group (497 cases) randomly. Routine nursing cares were used in the control group,while the comfortable nursing cares were used in the experimental group in addition. QLQ-C30 was used to evaluate the level of patients'quality of life at the time of beginning, ending and the midpoint of the treatment. Results There was no significant difference between the two groups about the QLQ-C30 values at the beginning of the treatment, while the differences were signifi-cant at the other two time points, the level of quality of life in the experimental group was better than in the control group. Conclusions Comfortable nursing can promote quality of life of patients with malignant tumor, which should be developed in the clinical field.

Objective To discuss effect of intellectual training on cognitive function, daily life ac-tivity and life quality of patients with Alzheimer's disease. Methods We used clinical dementia rating (CDR) scale to selecf 38 patients with mild to median degree of Alzheimer's disease.Intellectual training was carried out for 1 year and at the same time their family members took part in it and dietary instruction was given. Mini-mental state examination (MMSE), information-memory-concentration test (IMCT) and activity of daily living scale (ADL) were used as evaluation tools before and after training. Results The patients' degree of defect before training was not different from that of within the first three months after training (P>0.05),but greatly alleviated 6 months and one year later (P< 0.05,P< 0.01 ). Conclusions Beneficial intellectual training could improve the cognitive function of patients with Alzheimer's disease.It alleviated their symptom,prolonged the process of dementia and increase the living and life quality of them.

Objective To detect the expression of HER2 and TOPOⅡ? in human breast cancer to explore the relationship between them and the potential value in the chemotherapy of breast cancer. Method 24 breast cancer tissues and paired normal tissues were investigated. RT-PCR and imumohistochemical staining were used to detect the expressions of HER2 and TOPOⅡ? at the transcription and protein level respectively. Results HER2 mRNA expressed positively in 29% (7/24) breast cancer tissues vs 4% (1/24) in paired normal tissues. The positive expression of TOPOⅡ? mRNA in breast cancer tissues and paired normal tissues were 92% (22/24) and 21%(5/24) respectively. The result of the immunohistochemical staining showed that the positive rates of HER2 and TOPOⅡ? in breast cancer tissues were 30%(6/20) and 94%(16/17) respectively, which was consistent with RT-PCR. The 6 cancer samples with HER2 positive expression coexpressed TOPOⅡ?. The expression of these two proteins was correlated(R=0.524,P

Objective To evaluate the effects of delayed remote limb ischemic preconditioning (DRLIP) on myocardial injury in patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB).Methods A total of 41 patients of both sexes,aged 55-70 yr,weighing 50-75 kg,scheduled for elective cardiac valve replacement under CPB,of ASA physical status Ⅱ or Ⅲ (NYHA Ⅱ or Ⅲ),were randomly divided into 2 groups using a random number table:control group (group C,n =20) and group DRLIP (n =21).In group DRLIP,the patients underwent three 5-min cycles of unilateral lower limb ischemia,induced by a manual cuff-inflator placed on the left thigh and inflated to 200 mmHg starting from 24 h prior to surgery.Blood samples were taken from the central vein before aortic clamping,at 6 h of reperfusion and at 24 h after surgery for determination of plasma cardiac troponin Ⅰ concentrations.Before aortic clamping and at the end of CPB,myocardial tissues were obtained from the right auricle for determination of the expression of caspase-3 and cell apoptosis.Apoptotic index was calculated.The recovery of spontaneous heart beats was recorded.Results Compared with group C,plasma troponin Ⅰ concentrations were significantly decreased at 6 h of reperfusion,and the expression of caspase-3 was downregulated,apoptotic index was decreased at the end of CPB,and no significant change was found in the incidence of recovery of spontaneous heart beats in group DRLIP.Conclusion DRLIP can protect myocardium against injury in the patients undergoing cardiac valve replacement under CPB,and inhibition of cell apoptosis is involved in the mechanism.
