Methods:Two hundred and ten women who had clinical indications for labor induction were randomly allocated into 5 groups: mife-pristone(A) ,Diluoan(B) ,oxytocin(C), misoprostol(D)and control(E)groups. Results: The cervical Bishop score in group Awas increased to 3.39-+0.87 and higher than those in other groups(P＜0.05). The success rates of labor induction andvaginal delivery in mifepristone combined with misoprostol or oxytocin were significantly higher than those in other groups(P ＜0.05). Conclusion: Mifepristone is an effective inductive agent for cervical ripening, misoprostol and oxytocin werestrong uterine contract revulsivum. Mifepristone combined with misoprostol or oxytocin was considered as the best way of la-bor induction in term pregnancy.

Objective To investigate the high resolution CT (HRCT) findings of pleura invasion of lung adenocarcinoma (stageⅠ) presenting as mixture ground glass nodule (mGGN).Methods 20 cases of lung adenocarcinoma presenting as mGGN were confirmed by pathology.The correlation of those cases with pleural adjacent relation and the relation between the maximum diameter and pleural invasion were analyzed retrospectively.Results (1)The classification of mGGN adjacent to the pleura relationship:type Ⅰ,typical and atypical pleural retraction sign,10 cases of this type did not show pleural invasion;type Ⅱa,the mGGN contacted pleural for ground glass opacity,4 cases of this type showed no pleural invasion;type Ⅱb,the mGGN contacted pleural for solid elements,6 cases of this type were with pleural invasion.(2)The difference of the maximum diameter of mGGN in groups pleural invasion and non-invasion was not significant statistically (P=0.694).Conclusion The mGGN contacted pleural for solid composition is a reliable sign in diagnosis of pleural invasion.

Objective To define a suitable and adequate sample volume for the detection of bacterial contamination in cord blood (CB) via BacT/ALERT system. Methods A total of 1 376 cord blood units were routinely screened for aerobic and anaerobic microorganisms by culturing the erythrocyte fraction(EF) or plasma fraction(PF) with 20 ml and 10 ml sample volume. The microbial contamination was detected by BacT/ALERT 3D system, and the results of this method were compared with the improved Martin/thiogly collate broth(22 ℃) and thioglycollate broth(35 ℃).Results The rates of positive BacT/ALERT results were 1.16%(10 ml) and 1.24%(20 ml) for PF, and 3.20%(20 ml) for EF. The positive rate of Martin/thiogly collate broth(22 ℃/35 ℃) was 1.00% for EF. Conclusion Using BacT/ALERT system for microbial detection in cord blood bank can enhance the security of umbilical cord blood transplantation.

Objective To investigate the influence of self-management and education on behaviors of medical compliance of patients undergoing vitrectomy combined with tamponade.Methods Sixty-four patients undergoing vitrectomy combined with tamponade were randomized equally into the control group and observation group in the order of admission.The control group received routine care and health education,while the observation group received self-management education follow-ups besides the routine nursing.The two groups were compared in terms of the cumulative time of the correct position,compliance behavior and the incidence of postoperative complications.Results The cumulative time of the correct position of observation group was longer than that of the control group after operation.The observation group did better in compliance behavior than the control group and the incidence of postoperative complications in the former group was lower than the latter(P<0.05).Conclusion Self-management and education can enhance patients’behaviors in medical compliance and decrease postoperative complications and promote the success of the surgery.

ResultsThe social support and quality of life of patients improved after intervention compared with those before intervention,and with improvement of social support,the quality of life was accordingly increased. ConclusionsSocial support under nursing intervention help to improve quality of life of HIV/AIDS patients,and can support evidence for education and strategies implementation of treatment compliance for HIV/AIDS patients receiving antiretroviral therapy.

BACKGROUND:In vitro and in vivo studies of cel response to a variety of mechanical loadings have demonstrated the stimulation of bone formation by loads. However, the effects of different mechanical strains on the same cel s have never been adequately studied by far.
OBJECTIVE:To investigate the effects of different mechanical strains on rat bone marrow mesenchymal stem cel s.
METHODS:Rat bone marrow mesenchymal stem cel s were isolated and cultured in vitro. Bone marrow mesenchymal stem cel s were subjected to different stimulations including dynamic stretch, static stretch and hybrid stretch through the use of custom-made mechanical stretch device. Cel ular proliferation, alkaline phosphatase activity and mRNA expression of Runx2 of bone marrow mesenchymal stem cel s were detected and the secretion of osteocalcin was evaluated under three different stretch modes respectively.
RESULTS AND CONCLUSION:Compared to the control group, cel proliferation increased by 18.67%, however, alkaline phosphatase activity, Runx2 expression and osteocalcin secretion were not changed obviously in the static stretchgroup. Compared to the control group, alkaline phosphatase activity, Runx2 expression and osteocalcin secretion increased by 60.33%, 49.67%and 48%respectively;however, cel proliferation was inhibited, in the dynamic stretch group. Compared to the control group, cel proliferation was slightly, but not significantly, increased in the hybrid stretch group, and the alkaline phosphatase activity, Runx2 expression and osteocalcin secretion increased although the increases were not as apparent as those in the dynamic stretch group. These findings suggest that static mechanical strain can significantly promote cel proliferation, the dynamic mechanical strain more greatly promotes osteogenic differentiation of bone marrow mesenchymal stem cel s, and the hybrid mechanical strain promotes the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cel s.
