BACKGROUND:Bone marrow mesenchymal stem cell (BMSCs) transplantation has been reported to promote the repair of uterine injury;Shenghuazhixue decoction functions to promote blood circulation and remove blood stasis, and dysmenorrhea. OBJECTIVE:To investigate the effect of BMSCs transplantation combined withShenghuazhixue decoction on subinvolution of uterus effect and the underlying mechanism. METHODS:The model of subinvolution of uterus was established in 40 femaleSprague-Dawley rats, followed by randomly divided into four groups: control,Shenghuazhixue decoction, BMSCs, and combination groups. The control group received no treatment; at the 1st day after modeling, 1×107/L BMSCs (1 mL) were injected into the rat myometrium in the BMSCs and combination groups before laparotomy; the rats in theShenghuazhixue decoction group received no treatment after incision of uterus, and then rinsed using normal saline before closing the abdomen; theShenghuazhixue decoction and combination groups were given 8 mL/(kg?d)Shenghuazhixue detectionvia gavage at the 1st day after modeling, once daily, for consecutive 7 days. Afterwards, the relevant indexes were detected. RESULTS AND CONCLUSION:Compared with the control group, the body weight, uterine wet weight and uterine index in the combined group were significantly decreased after treatment (P < 0.05). The body weight and uterine wet weight showed significant differences betweenShenghuazhixue decoction and control groups (P < 0.05). Compared with the control group, the expression levels of intrerleukin-1 and tumor necrosis factor-α were significantly decreased, and the serum level of thromboxane B2 was significantly increased in theShenghuazhixue decoction group after treatment (P < 0.05). After treatment, the expression levels of intrerleukin-1 and tumor necrosis factor-α were significantly decreased, and the level of vascular endothelial growth factor was significantly increased in the BMSCs group compared with the control group (P < 0.05). Compared with the control group, there was significant decease in the expression levels of intrerleukin-1 and tumor necrosis factor-α, and significant increase in serum level of thromboxane B2 and vascular endothelial growth factor in the combination group (P < 0.01). These results suggest that BMSCs transplantation combined withShenghuazhixue detection can reduce postpartum body weight, uterine wet weight and index of uterus, and promote uterine involution in female rats, which may be through decreasing the levels of intrerleukin-1 and tumor necrosis factor-α as well as increasing the levels of thromboxane B2 and vascular endothelial growth factor.

Objective To compare the effect of midazolam and propofol on cytokine balance in patients undergoing cardiac valve replacement under CPB. Methods Twenty NYHA class Ⅱ - Ⅲ patients with rheumatic heart disease scheduled for elective cardiac valve replacement under CPB were randomly divided into 2 groups: midazolam group (M, n = 10) and propofol group (P, n = 10) . Patients with preoperative hepatic and renal dysfunction, coagulation defect and diabetes, primary hypertension and coronary artery disease were excluded. The patients were premedicated intramuscular morphine 0.1 mg?kg-1 and oral diazepam 0.1 mg?kg-1. Anesthesia was induced with midazolam 0.06-0.1 mg?kg-1 (group M) or propofol 1.0-1.5 mg?kg-1 (group P) and scopolamine 0.6 mg, fentanyl 4-10 ug?kg-1, vecuronium 0.1 mg?kg-1 and lidocaine 1.5 mg?kg-1, and maintained with intermittent iv boluses of midazolam 0.04-0.1 mg? kg-1 (group M) or propofol intravenous infusion at a rate of 3-5 mg?kg-1?h-1 supplemented with intermittent boluses of fentanyl and vecuronium. PETCO2 was maintained at 30-40 mm Hg during mechanical ventilation. BP, HR, ECG, CVP, PETCO2, SpO2 , nasal and rectal temperature were continuously monitored during operation. Blood samples were taken from artery before anesthesia (T1), at vena cava catheterization (T2), 30min after aortic cross-clamping (T3) and 10 min (T4), 1 h (T5), 2 h(T6), 4 h(T7) and 24 h(T8) after declamping of aorta for determination of Hct, IL-1, IL-8 and IL-10 by using ELISA. Results Plasma concentrations of IL-6, IL-8 and IL-10 were significantly increased at T4-7 as compared with the baseline value before anesthesia (T1) in both group. Plasma concentration of IL-8 in group P was significantly lower than that in group M at T7 ( P

Objective To explore the status quo of the career planning of the second child nursery under the two-child fertility policy, and to provide reference for carrying out the targeted management intervention. Method From April to May of 2017, 592 nurses of the second child were surveyed using the general data questionnaire and the career planning scale. Results The nurses' career planning score (34.81 ± 3.59) was different, and the career planning of the two nurses with different age, job title, title, establishment, department and income and fertility was different and statistically significant. Nurses with plan to a second child are with less desire to further study and promotion than those without plan to a second child (all P<0.001) promotion to open more than two children before the low policy (P <0.05). Conclusion Nurses' career planning for births is on a middle level. Nursing managers should pay attention to the management of nurses' career planning , create a career development environment , provide humanistic care , strengthen self-awareness and career self-development of nurses who have two births , so as to improve the level of their career planning to promote the nursing team development.

Quorum sensing is defined as the cell density-dependent regulation of gene expression, and the involved system is the quorum sensing system, in which N-acyl homoserine lactone is known as the signal molecules of most gram-negative organisms. It can regulate diverse physiological functions. This paper reviewed the quorum sensing systems and the recent advances which play a major role in the formation of the symbiosis between the rhizobia and their host plants.

Objective To investigate the characteristics of pathogens and risk factors of the catheterassociated infection (CAI) in emergency ICU (EICU) in order to design an appropriately therapeutic strategy for the future.Methods From January 2008 to December 2010,a total of 1363 patients were enrolled for this retrospective study.Blood sample taken from the vein with indwelling catheterization and the tips of catheters cut in 5 cm after withdrawn from the veins in 1363 patients were collected for bacterial culture.Results Of 1363 catheters,pathogens were found in 147 (10.79％) after venous catheterization.The daily occurrences of CAI were 3.05 ones per 1000 catheters.Of 147 cases of infection,46.94％ pathogens were gram-negative bacilli,40.14％ gram-positive cocci,and 12.92％ fungi.Unconditional Logistic regression analysis suggested that repeated catheterization,femoral vein catheterization,the application of multi-lumen catheter and long-term indwelling catheterization were the independent risk factors responsible for CAI.Conclusions The risk factors responsible for catheter related infections should be controlled to prevent the occurrence of nosocomial infection.

Objective To explore the incidence,features and outcomes of in-hospital sudden cardiac death (SCD) in order to determine the predictors of survival. Methods The clinical data of 69 patients with cardiac arrest hospitalized from January 2008 through December 2010 were retrospectively analyzed.Information on genders,age,types of arrhythmia was collected and further analyzed to determine these factors associated with the occurrence and outcomes of in-hospital cardiac arrest. Results The overall incidence of SCD was 47.3 / 100 000 per year and 17.4％ of them.survived at discharge.The occurrence rate was higher in male than that in female (66.7％ vs.33.3％,P ＜0.01 ),whereas difference in gender did not affect the discharge rate ( P ＞ 0.05 ). Survivors from in-hospital cardiac arrest were significantly younger than non-survivors (man:62.57 ± 12.83 years vs.75.56 ± 10.55 years; women:60.36 ± 13.24years vs.69.53 ± 11.72 years,P ＜ O.01 ).From 62 ECG records of SCD patients,the incidence of nonshockable rhythms was higher than that of shockable rhythms.Compare to the non-shockable rhythms,the shockable rhythms brought a higher rate of restoration of spontaneous circulation (ROSC) (54.5％ vs.24.5％,P ＜0.05),whereas survival rates at discharge between two groups were not statistically different ( 18.2％ vs.18.4％,P ＞ 0.05 ).Conclusions Non-shockable rhythms were more common in patients suffering from in-hospital cardiac arrest.Although defibrillation treatment contributed benefit to ROSC among patients with ventricular fibrillation or pulseless ventricular tachycardia,high-quality CPR and post-cardiac arrest care may play a more critical role in the outcomes of in-hospital sudden cardiac death.
