Objective To investigate midwives' role cognition and their working experience.Methods It was a qualitative study using the phenomenological method.10 midwives were interviewed and all the data were analyzed using the categorization method.Results Three main categories were identified:diversified midwife roles; capacities and qualities required to fulfill midwifery roles; positive and negative experiences coexisted.Conclusions Managers should develop humanized management approaches to facilitate the fulfillment of midwives' roles and improve their working experience.The research also revealed the need to improve Chinese midwifery education and the midwifery regulation systems.

Objective To study the effect of ursolic acid(UA) on apoptosis of the ovarian cancer cell line SKOV3 and its action mechanisms. Methods The SKOV3 cells were treated with UA at different concentration. The proliferation inhibition was examined by MTT assay. Morphological examination and flow cytometry were used to detect apoptosis. RT-PCR and immunocytochemical method were used to detect the expression of wild type p53,an apoptosis related genes. The semi-quantification of protein expression was analyzed by pathological image-analysis. Results UA inhibited the proliferation of SKOV3 cells strongly. Apoptosis of SKOV3 cells were induced by UA treatment. The morphology of SKOV3 showed changes such as chromatin aggregation, nuclear and cytoplasmic condensation and apoptotie bodies appearance. UA caused significant G0/G1 arrest with a concomitant decrease of cell population in S and G2/M phases. Apoptotic cells were found by flow cytometry. The maximal early apoptotic rate was (28.7±2.4)% when exposed to 40 μmol/L for 48 h. The expression of p53 gene and protein was enhanced. All these effects were in a dose and time-dependent manner Conclusion UA induced apoptotic processes in the ovarian cancer SKOV3 cell line were the mechanism involving p53 pathway.

To analyze the specific mechanism of Jinxueyuan granules, the relationship between the Jinxueyuan granules increased the saliva secretion of xerostomia model SD rats and excitement of receptors were studied in this experiment. In the study, three groups of xerostomia model rats were successfully established by using M-receptor blockers-4-diphenyl-acetoxy-N-methyl-piperidine (4-DAMP) and atropine, or adrenergic receptor blocker phentolamine; after the modeling, the medicine Jinxueyuan granules were gavaged. According to the clinical dose of Jinxueyuan granules and SD rats body surface area, the rats in atropine group were divided three dose groups respectively, namely low, medium and high dose of Jinxueyuan granules groups. The 4-DAMP group and phentolamine group were gavaged medium dose of Jinxueyuan granules. And the amount of salivary secretion for 150 minutes in all groups continuously were measured, and the effect of Jinxueyuan granules increased salivation and the relationship between characteristics and the receptors were observed; and submandibular gland tissue of the rats was isolated, then the effect of Jinxueyuan Granules for expression of the water channel protein aquaporin-5 (AQP5) in submandibular gland cells was analyzed by the Western blot technology. It was found that the saliva secretion of Jinxueyuan Granules groups was increased significantly, and compared with the saline control group, phentolamine group, 4-DAMP group and atropine group, difference was significant, P < 0.05. There was no significant difference between the low-dose of Jinxueyuan granules group and the saline group, but the medium dose of Jinxueyuan granules group had a significant difference, compared with the saline group (P < 0.05). In the time distribution of increasing saliva secretion, there was a significant difference between the saline and Jinxueyuan granules group in the saliva secretion (P < 0.05). After administration of Jinxueyuan granules, the expression of AQP5 protein in the submandibular gland cells expressing of treatment groups was increased, and compared with the blocker groups, there was a significant difference, P < 0.05. Except the atropine group, there was no significant difference in Jinxueyuan granules relieving the inhibition induced by blocks in phentolamine group and 4-DAMP group, compared with the saline group. Compared the AQP5 expression in three blockers groups, there was no significant difference in the efficacy of Jinxueyuan granules between phentolamine group and 4-DAMP group; but there was a significant difference between the atropine group and other groups (P < 0.05). Therefore, it was considered that the mechanism of Jinxueyuan granules increasing saliva secretion (effectiveness of nourishing Yin and generating body fluid ) possibly through the pathway mediated by muscarinic M receptor, especially M3 receptor, or adrenergic receptor, and increased expression of salivary gland AQP5 membrane, and then stimulate saliva production.

Professor ZHOU Yun-xian's clinical experience of acupuncture combined with Chinese material medica for xerophthalmia is introduced. Her treatment for xerophthalmia is firstly focused on syndrome differentiation, indicating that different syndrome has different treatment of acupuncture and Chinese material medica. It is emphasized that by following the holistic concept of TCM, the local acupoints and whole-body acupoints cooperate closely, forming her special combination method of acupoints. In clinic, attention is focused on the application of many acupuncture techniques and extra points. With the combination of acupuncture and Chinese material medica, the treatment is flexible with superior clinical efficacy.

Objective To investigate whether enteric nervous system(ENS)involve in mediating the effect of short pulse gastric electrical stimulation on c-fos expression in nucleus tractus solitarius (NTS)and hypothalamus.Methods Fifteen Wistar rats were divided into control group,gastric electrical stimulation(GES)group and ENS free group with 5 rats each.A pair of electrodes was implanted on the gastric serosa.In ENS free group,0.5%benzalkonii chloridum was applied on the serosa during the surgery.A set of short pulse GES with frequency of 20 cpm,pulse width of 300 μs and amplitude of 2 mA was applied via the electrodes for 30 rain in the stimulation group and ENS free group.The c-fos expression in NTS/hypothalamus was detected 1 h after the stimulation.Results The number of neuron with c-fos expression was(71.6±7.4)/HP in NTS group and(63.4±10.8)/HP in ENS free group,both were significantly higher than those in control group(36.4±8.6/HP,P＜0.05).The number of neuron with c-fos expression in hypothalamus was higher in GES[(224.2±47.3)/HP]and ENS free groups[(249.1±44.0)/HP]compared with control group[(90.2±47.3)/HP,P＜0.05].There was no significant difference in c-fos expression in NTS/hypothalamus between GES group and ENS free group(P＞0.05).Conclusions Short pulse gastric electrical stimulation significantly increases c-fos expression in NTS/hypothalamus,which suggests that NTS/hypothalamus may participate in mediating the effect of GES on gastric function.This effect may be not mediated by ENS.

Objective To evaluate the reliability and validity of Midwife Core Competency Scale.Methods A total of 369 midwives from 32 hospitals in Beijing were investigated by using the Midwife Core Competency Scale,and the reliability and validity were measured.Results The scale had good internal consistency (Cronbach's α =0.950) and stability (the test-retest reliability was 0.832).The distribution of 54 items in 6 public factors (the cumulative variance＝68.405％) extracted from them was consistent with the original scale,yielding an acceptable construct validity.The scale also had good validity to discriminate different categories.Conclusions The Midwife Core Competency Scale had good reliability and validity,which provides an useful tool to evaluate midwifes' core competency.Larger sample from different areas need to be considered for scale improvement and application.

Midwifery competency is the foundation for sustainable development of the midwifery profession. The promotion of midwives′ competency can improve their ability, strengthen midwifery competitiveness and enhance the quality of midwifery care services. This study gave an overview of the worldwide research progress on midwifery competency, we can draw the conclusion that there are urgent needs to improve midwifery education programs in China, emphasize competency-based midwifery education, as well as standardize the in-service training system to support the development of midwifery competency.
