ObjectiveTo investigate the factors related with curative effect and prognosis of postoperative radiotherapy for nasal and paranasal sinuses carcinoma.MethodsThe data of 95 patients with nasal and paranasal sinuses carcinoma and received postoperative radiotherapy were reviewed retrospectively. Kaplan-Meier method was used to analyze the survival, Logrank test used to compare the differences between different groups. Multivariate analysis was performed by Cox proportional hazard model.ResultsThe overall 1, 3, 5, 10-year survival rates of 95 patients were 84.2%, 50.5%, 44.2% and 20% respectively. Univariate analysis showed that sex, age, operative modality and tumor dose were not related with survival. Histological and clinical stages were related with survival. Multivariate analysis indicated that histological and clinical stages were independent prognostic factors. The follow-up results showed that visual disturbance, xerostomia, dysaudia were the major side effects.ConclusionPostoperative radiotherapy can improve therapeutic effect in the treatment of nasal and paranasal sinuses carcinoma, and histological and clinical stages are the independent prognostic factors effecting prognosis.

To investigate the anticancer effects of ring C in 18β-glycyrrhetinic acid (GA), a series of GA derivatives featured with 9(11)-ene moiety in ring C were designed and synthesized. The structures were confirmed by IR, LC-MS and 1H NMR. Their inhibitory effects towards human prostate cancer PC-3 and leukemia HL-60 cell lines were determined. Most of the derivatives displayed stronger antiproliferative activities than GA. Particularly, compound 14 showed promising anticancer activity with the GI50 values of 4.48 µmol · L(-1) and 1.2 µmol · L(-1) against PC-3 and HL-60 cells respectively, which is worth further study.

Objective： The current study was designed to investigate the expression of p73 gene in lung cancer tissue. Methods： The authors detected quantitatively p73 gene expression in 40 specimens of lung cancer and matched paracancer tissue by RT PCR and analyzed the alteration of p73 by PCR and SSCP. Results： ① Using RT PCR, 24 specimens of lung cancer were determined to be overexpression of p73, 9 of which were moderately differentiated, 15 of which were poor differentiated; 9 of which were Stage Ⅰ-Ⅱ , 15 of which were Stage Ⅲ-Ⅳ . No specimen of paracancer tissue was screened out to be overexpression of p73. There was significantly different expression rates between lung cancer and paracancer tissue (P< 0.01). ② Allele specific analysis showed that expression of G/C： A/T appeared in 10 of 12 heterozygous lung cancer specimens and expression of G/C in 27 specimens. ③ No mutation was detected by SSCP. Conclusion： The expression of p73 gene may be related to differentiation level of lung cancer but not related to clinical stage.

Objective To study the current situation of emergency nurses' structural empowerment,competency,job satisfaction,and their correlative factors.Methods Literature review, interview and questionnaire were used to establish the emergency nurses' structural empowerment and competency model.300emergency nurses were structurally empowered,and their quality of care and job satisfaction was compared before and after.Results The quality of care and job satisfaction after structural empowerment was (98.45 ±1.36) and (98.19 ± 2.63 ),both of which were higher than that before structural empowerment (95.33 ±2.47) and (93.81 ± 4.54),and the differences were statistically significant (t =-4.468,16.136,respectively; P ＜ 0.05).After structural empowerment,there was great improvement in emergency nurses' selfevaluation,as well as their ability of critical thinking,receiving information,communication and health education,while there was little improvement in their ability of social support,logical reasoning and innovation.Conclusions Establishing structural empowerment and competency model for emergency nurses helps them position themselves and promote their development,as well as provides reference to select and train professional nurses for hospitals.

OBJECTIVETo observe the effect of needling "Housanli" (ST 36) with different retaining-needle time on the pain threshold of mice using the hot water tail-flick test, and investigate the relationship between the retaining-needle time and the therapeutic effect.

METHODSTwenty-four healthy mice were randomly divided into four groups: no retaining-needle group (group A), retaining-needle 10 min group (group B), retaining-needle 20 min group (group C) and retaining-needle 30 min group (group D), with 6 mice for each group. After acupuncture "Housanli", the tail of mouse was put into the hot water at 50 degrees C, and the intervening time from the tail entered water to the tail flicked out of water was recorded and analyzed for each group.

RESULTSAfter acupuncturing "Housanli", the pain threshold was significantly improved with the hot water tail-flick test in both group A and group C (both P<0.01), however, there was no significant difference in both group B and group D (both P>0.05). Within 30 min of retaining-needle, the effect curve of acupuncture analgesia was showed in a waved line. In contrast, the maximum value of latent period on the tail-flick was detected in the group C that was the biggest effect of acupuncture analgesia among the four groups.

CONCLUSIONThe best retaining-needle time of hand-acupuncture for acupuncture analgesia is 20 min.

ObjectiveTo evaluate the neurobiological characteristics of human histio-amniotic mesenchymal (hAMCs) and effect of hAMCs transplantation into the brain to treat Parkinson's disease(PD) modle mice.MethodsThe expressions of mesenchymal stem cells, neural stem cells, dopaminergic neurons and markers related to neurogenesis such as Vimentin, STRO-1, nestin, CD133, β-tubulin, TH, DAT, Ngn2 and mash-1 in hAMCs were evaluated through immunocytochemical stain; and the mRNA transcriptions of neural stem cell markers, Vimentin and nestin in hAMCs were detected by RT-PCR. The PD model was induced by MPTP(i.p.) in C57BL/6 mice transplanted with hAMCs into the right striatum. The therapeutical effect of hAMCs on PD mice was evaluated by spontaneous movement, rotating bar test and the immunohistochemistry of anti-human chondrosome and TH antibodies in striatum.ResultshAMCs induced by nerve cells culture medium, expressed mesenchymal stem cells, neural stem cells, dopaminergic neurons and other specific markers related to neurogenesis mentioned above. The frequency of spontaneous movement in PD mice was significantly increased(P<0-05), and the time of rotating bar was obviously prolonged(P<0-05) after transplantation with hAMCs.ConclusionhAMCs possess the characteristics of nerve cells after cultured in vitro and can significantly recover the damage of motor function induced by MPTP after transplantation into striatum in PD model mice.

OBJECTIVETo investigate the effect of moxibustion at Sanyinjiao (SP 6) for uterine contraction pain in labor, and evaluate the safety of the parturient and newborn.

METHODSOne hundred and seventy-four cases of singleton pregnancy and cephalic presentation primipara were single blinded and randomly divided into three groups: observation group (59 cases), placebo treated group (57 cases) and blank group (58 cases). The observation group was treated with moxibustion at Sanyinjiao (SP 6) for 30 min when the uterus cervix openning at 3 cm, the placebo treated group was treated with moxibustion at no acupoint for 30 min and the blank group was treated with routine labor nursing, the uterine contraction pain and the safety of the mother and infant were compared among three groups.

RESULTS1) The uterine contraction pain was tested by Visual Analogue Scale (VAS): the scores of VAS in the observation group were obviously decreased after 15 min and 30 min of moxibustion (both P<0.05), there were no obvious changes of the VAS scores in placebo treated group and the blank group, the scores of VAS in observation group decreased much more obviously than those in the other two groups (all P<0.05); 2) Midwife rating of the uterine contraction pain: after 30 min of moxibustion, the effective rate of labor analgesia was 69.5% (41/59) in observation group, which was higher than that of 45.6% (26/57) in placebo treated group and 43.1% (25/58) in blank group, with significant differences between them (both P<0.05); 3) The postpartum hemorrhage amount of the observation group was obviously lower than those of placebo treated group and blank group (both P<0.05); 4) The Apgar score of newborn was higher in observation group and placebo treated group than that of blank group (both P<0.05).

CONCLUSIONMoxibustion at Sanyinjiao (SP 6) can relieve the uterine contraction pain, and has no side effect to mother and infant, it is one of the safe, effective and simple non-drug analgesia methods.
