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.

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.

The self-made high sensitivity and selectivity micro-biosensor was applied to monitor the change of dopamine in cerebral nucleus in rats in vivo. The micro-biosensor was prepared and used to detect dopamine level in vitro and monitor the dynamic change of dopamine in different cerebral nucleus in vivo. The results showed the lowest concentration of dopamine that could be detected by the biosensor was 32.5 nmol/L. Its positive peak was significantly different from that of AA, 5-HTP and E. The biosensor could keep working for monitoring the dopamine concentration in the cerebral tissue for more than 10 h. It was concluded that the microsensor has high sensitivity and selectivity to dopamine and can be used to dynamically monitor the change of dopamine in vivo.

Objective To explore the clinical efficacy and side effect of hepatocyte growth - promoting factor in treatment of infant hepatitis syndrome. Methods Sixty one cases of infant hepatitis syndrome were chased as the treatment group who hospitalized in our hospital from March 2002 to Feb 2003,and 54 cases of infant hepatitis syndrome as control group who hospitalized during March 2001 to Feb 2002. The treatment group were administrated with hepatocyte growth - promoting factor for 2 weeks. We obser-ved the recovery of patient's liver function (TBIL.ALT, AST) and the side effect of hepatocyte growth- promoting factor after two weeks of the treatment. Results After the treatment,TBIL and ALT decreased significantly in the treatment group of infant hepatitis syndrome. The treatment group was superior to the control group (P

Currently, the resistance of first-line anti-tuberculosis drugs has made the prevention and treatment of tuberculosis increasingly difficult, posing a serious threat to global public health. Several studies have shown that efflux pumps are one of the important causes for bacteria to develop multi-drug resistance and extremely-drug resistance, and efflux pump inhibitors can inhibit the efflux of antibacterial drugs, thereby reducing bacterial drug resistance. Numerous natural products and synthetic compounds have been reported to possess efflux pump inhibitory activity, but they have not been applied in clinical settings because of their toxicity, pharmacokinetic properties,

SW872 preadipocytes were cultured and induced to differentiate by oleic acid in vitro.The levels of adiponectin and its receptors (AdipoR1 and AdipoR2) mRNA were measured by semiquantitative RT- PCR.The concentration of adiponectin in the culture medium was assayed by ELISA.The results showed that rhIL- 6 could inhibit adiponectin,AdipoR1 mRNA expressions and adiponectin secretion in SW872 adipocytes in a time- and dose-dependent manner,but did not influence adipoR2 mRNA expression.

OBJECTIVE To analyze the incidence of anatomic variations of the temporal bone to provide valuable reference for clinical otology. METHODS Sev-enty six healthy adults (152 ears) and 66 patients(96 ears) with chronic suppurative otitis media confirmed by clinical examination underwent axial and coronal High-resolution Computed Tomography(HRCT) scan. The incidence of high jugular bulb, dehiscent jugu-lar bulb, anterior location of sigmoid sinus, low-lying middle cranial fossa, dehiscent tegmen tympani, mas-toid antrum dysplasia, aberrant internal carotid artery, and large sinus tympani were recorded. RESULTS In normal, abnormal, well and poorly pneumatized groups, the incidence of highly positioned jugular bulb on the right was higher than that on the left. The total inci-dence of high jugular bulb on the left and right was 26.2 % and 46.0 % respectively. The incidence of ante-rior location of sigmoid sinus in the abnormal group (32.3 %) was higher than that in normal group(15.8 %), which was higher in poorly pneumatized group(43.5 %) than that in well pneumatized group(11.3 %). The inci-dence of dehiscent tegmen tympani in well pneuma-tized group(18.0 %) was higher than that in poor pneu-matized group(8.7 %). There was no significant differ-ence in dehiscent jugular bulb, low-lying middle cranial fossa, mastoid antrum dysplasia, aberrant internal ca-rotid artery, and large sinus tympani between the left and right within and among groups. The incidence of these varia-tions was 2.0 %,21.8 %,1.2 %,0.4 %,0.8 %respectively. CONCLUSION HRCT can show ana-tomic variances of temporal bone clearly before opera-tion and has great clinical value for reducing the inci-dence of complications caused by middle ear operation.
