Objective To investigate the role of nursing group leaders in nursing level management Methods 19 nursing staff were divided into the observation group ( 10 nurses)and the control group (9 nurses). The observation group implemented the nursing level management, that was head nursesnursing group leaders-responsibility nurses, specific to the person in charge of patients, the treatment and nursing work was completed under the instruction of nursing group leaders. The control group obeyed the following patterns: head nurses-responsibility nurses. The test results of professional knowledge, comprehensive care quality of wards, satisfaction degree of patients and other indicators were compared between the two groups. Results Scores of technical operations and professional knowledge were significantly higher than the control group, the difference was statistically significant. The scores of ward care quality and health education coverage of patients were significantly higher, adverse event rate was significantly lower than the control group, the difference was statistically significant. The satisfaction degree of doctors and patients was significantly higher than the control group, the difference was statistically significant. Conclusions The implementation of the nursing level management by appointing group leaders can help improve the level of nursing services, ward care quality, patient satisfaction and thus ensure high-quality care to carry out effectively.

OBJECTIVE:To observe therapeutic efficacy and safety of Leonurus artemisia injection combined with carboprost tromethamine for preventing postpartum hemorrhage (PPH) of pregnant women after cesarean section. METHODS:177 pregnant women undergoing cesarean section were randomly divided into control group(87 cases)and observation group(90 cases). Preg-nant women of both groups received cesarean section. Control group was given intramuscular injection of oxytocin 20 U in uterine muscle wall above the incision after the foetus parturition,and given intravenous dripping of oxytocin 20 U added into 0.9% sodi-um chloride 250 mL;4 h after the operation,the pregnant women received intramuscular injection of oxytocin 10 U,every 12 hours,for 3 days. Observation group was given intramuscular injection of L. artemisia injection 2 mL and Carboprost tromethamine injection 1 mL in uterine incision after the foetus parturition;4 h after the operation,the pregnant women received intramuscular in-jection of L. artemisia injection 2 mL and Carboprost tromethamine injection 1 mL,and then give L. artemisia injectien 2 mL,ev-ery 12 hours,for 3 days. Clinical efficacies of 2 groups were observed as well as blood loss during operation,2 h after operation and 24 h after operation,the amount of hemoglobin(Hb)before operation and 24 h after operation,height of uterine fundus 3,7 d after operation,the occurrence of ADR. RESULTS:The total response rate of observation group was significantly higher than that of control group;blood loss during operation,2 h after operation and 24 h after operation,height of uterine fundus 3,7 d af-ter operation were also significantly than control group,with statistical significance(P<0.05). There was no statistical significance in Hb of pregnant women between 2 groups before operation(P>0.05). 24 h after operation,Hb of pregnant women in control group was significantly lower than before operation and observation group,with statistical significance(P<0.05);there was no sta-tistical significance in Hb of observation group between before operation and 24 h after operation(P>0.05). There was no statisti-cal significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:L. artemisia injection combined with car-boprost tromethamine shows significant therapeutic efficacy for PPH of pregnant women underwent cesarean section,can signifi-cantly reduce intraoperative and postoperative blood loss,accelerates the recovery of uterus without increasing the rate of ADR.

Objective To investigate whether intervention with two different dosage of atorvastatin may benefit to plasma level of fibrinogen (Fg) in patients with acute cerebral infarction. Methods One hundred and two patients with acute cerebral infarction were randomly assigned into three groups:the control group (33 cases) treated without lipid-lowering drugs, 10 rag (30 cases) and 20 mg (39 cases) atorvastatin group with 3 days of treatment. Before and after the treatment, the plasma levels of Fg and lipids were detected.Results The treatment of 10 mg atorvastatin did not significantly decrease the level of Fg. Compared to the control group, the level of Fg was markedly reduced by 20 mg atorvastatin (21.6% vs 3.2%,P< 0.05). No changes of lipid levels were observed in any group before and after the treatment, whilst there was no relation between the decreasing percentage of Fg and that of TC(r = 0.125 ,P= 0.618), TG(r = 0.147,P = 0.573) or LDL- C (r = -0.279, P = 0.235 ), HDL-C (r = -0.021, P = 0.157). Conclusion Treatment with high dose atorvastatin (20 mg) for 3 days could reduce the level of Fg, and improve the function of vascular endothehum,which may promote the stabilization of atherosclerotic plaque.

Acute lung injury(ALI)/acute respiratory distress syndrome(ARDS),the complicated and devastating illness,resulted from various processes of systemic inflammatory response syndrome(SIRS),injure directly or indirectly the lung.With the advance of investigations in SIRS and multiple organs disfunction syndrome(MODS),inflammation development and control have been considered to be the important mechanism of ALI/ARDS.The research hotspot is also focused on the inflammatory cells and cytokines.Dachengqi decoction can influence on the functions of inflammatory cells and cytokines,so the strategies of anti-inflammatory treatment on immunoregulation became the key point for prevention and treatment of ALI/ARDS with traditional Chinese medicine.

To establish a stable and reliable model of refractory hypoxemia acute respiratory distress syndrome (ARDS) and examine its pathological mechanisms, a total of 144 healthy male Wistar rats were randomized into 4 groups: group I (saline control group), group II (LPS intravenous "single-hit" group), group III (LPS intratracheal "single-hit" group) and Group IV (LPS "two-hit" group). Rats were intravenously injected or intratracheally instilled with a large dose of LPS (10 mg/kg in 0.5 mL) to simulate a single attack of ARDS, or intraperitoneally injected with a small dose of LPS (1 mg/kg) followed by tracheal instillation with median dose of LPS (5 mg/kg) to establish a "two-hit" model. Rats in each group were monitored by arterial blood gas analysis and visual inspection for three consecutive days. Arterial blood gas values, lung wet/dry weight ratio and pathological pulmonary changes were analyzed to determine the effects of each ALI/ARDS model. Concentrations of TNF-alpha, IL-1 and IL-10 in the bronchoalveolar lavage fluid (BALF) and blood plasma were measured by using enzyme-linked immunosorbent assays (ELISA). Our resulsts showed that single LPS-stimulation, whether through intravenous injection or tracheal instillation, could only induce ALI and temporary hypoxemia in rats. A two-hit LPS stimulation induces prolonged hypoxemia and specific pulmonary injury in rats, and is therefore a more ideal approximation of ARDS in the animal model. The pathogenesis of LPS two-hit-induced ARDS is associated with an uncontrolled systemic inflammatory response and inflammatory injury. It is concluded that the rat ARDS model produced by our LPS two-hit method is more stable and reliable than previous models, and closer to the diagnostic criteria of ARDS, and better mimics the pathological process of ARDS.

OBJECTIVE:To investigate the improvement effect of Eucalyptol enteric soft capsule on mice with lipopolysaccha-ride(LPS)-induced acute lung injury(ALI). METHODS:60 mice were randomly divided into blank control group,model control group,Eucalyptol enteric soft capsule low-dose,medium-dose,high-dose groups(100,300,900 mg/kg),12 in each group. Mice in administration groups were intragastrically given relevant medicines,mice in blank control group and model control group were intragastrically given equal volume of normal saline(0.1 mL/10 g). After 2 h of administration,except for the blank control group, ALI was induced in other groups by atomized LPS. After 6 h of modeling,the mice were sacrificed,alveolar lavage fluid(BALF) and lung tissue were taken. Morphological changes of lung tissue were observed under microscope;number of total cells,neutro-phils in BALF were calculated by blood cell count plate and staining by wright-giemsa respectively. Total protein concentration in BALF supernatant was detected by BCA method;TNF-α,IL-6 contents in BALF supernatant were determined by enzyme-linked immunosorbent assay. RESULTS:Compared with blank control group,lung tissue of mice in model control group showed obvious pathological damage and severe pulmonary edema;number of total cells,neutrophils in BALF,total protein concentration and TNF-α,IL-6 contents in BALF supernatant were significantly increased(P<0.01). Compared with model control group,pathologi-cal damage in lung tissue of mice was obviously improved in Eucalyptol enteric soft capsule high-dose group,number of total cells,neutrophils in BALF,total protein concentration and TNF-α,IL-6 contents in BALF supernatant were significantly decreased (P<0.05);and there were no significant differences in other groups (P>0.05). CONCLUSIONS:High-dose Eucalyptol enteric soft capsule can obviously improve LPS-induced ALI of mice.

Breast cancer is one of the most common cancers in women. Current clinical prognostic indicators and practice guide-lines show that almost 70% of node-negative and 30% of lymph node-positive breast cancer patients can survive 5-10 years without dis-tant metastasis after surgery. Patients also unnecessarily suffer the side effects of chemotherapy. Assays on multi-gene expression levels as prognosis prediction indicators have been successfully used to predict the prognosis of breast cancer patients because of the abnor-mal expression levels of a series of metastasis-related genes in cancer cells with high metastatic potential. In this review, we highlight the progress of research on predicting breast cancer prognosis based on multi-gene expression levels detected by microarray and qRT-PCR methods.
