Objective To study the effect of hospital disposal manners after workplace violence in hos-pital on organizational commitment and turnover intention among the head nurses. Methods Self-made questionnaire about workplace violence in hospital and general condition, organizational commitment question-naire and turnover intention questionnaire were conducted in 122 head nurses who had suffered hospital vio-lence in recent years from all level hospitals of Fujian province. Results The scores of affective commitment and normative commitment of organizational commitment and turnover intention showed significant difference be-tween the groups who suffered positive disposal and who suffered negative interference by the hospital after the violence events (P<0.05), but aggregate score of organizational commitment and the scores of continuance commitment showed no significant difference between the two groups (P>0.05). Hospital disposal manners af-ter the hospital violence and hospital grade were influence factors on turnover intention among the head nurses.Hospital grade was also an influence factor on organizational commitment among the head nurses. Conclu-sions Hospital positive disposal means after the hospital violence on head nurse help to ameliorate organiza-tional commitment and reduce turnover intention among the head nurses.

Objective To investigate the way of gene therapy on congestive heart failure and other heart diseases. Methods Recombinant adeno associated viruses (AAV) encoding the human ? 2 adrenergic receptor(AR) and enhanced green fluorescent protein (EGFP) were constructed and the ? 2 AR and EGFP cDNA were transfected in vitro to the neonate rat ventricular myocytes. The expression of ? 2 AR and EGFP on cultured neonate rat ventricular myocytes and the ability of ? 2 AR to potentiate the beta adrenergic signaling were assessed. Results The presence of human ? 2 AR mRNA was demonstrated by Northern blot, the expression of the ? 2 AR gene was demonstrated by Westernimmuno blot. The density of ? AR in the myocytes was greater than that in the control 〔(204.0 ? 6.4) fmol/mg protein vs (76.0 ? 2.8) fmol/mg protein〕 according to a ligand binding assay. Human ? 2 AR gene significantly increased isoproterenol stimulated cAMP as compared with the control〔(116.2?5.8) pmol/10 6 cell vs (58.4 ? 4.6) pmol/10 6 cell〕. EGFP was also expressed in the transfected cardiomyocytes. Conclusions Human ? 2 AR gene could be transfected into cardiomyocytes by AAV vector and could potentiate the beta adrenergic signaling.

Objective In this retrospective study, we analyzed the magnetic resonance imaging (MRI)and computed tomography(CT)scans of patients with prostate cancer to investigate the relationship between the apex of prostate and the anatomic structures visible in CT, and to provide evidence for localizing the prostatic apex in radiation treatment planning. Methods MRI and CT scans from 108 patients with prostate cancer were analyzed to measure the distance between the prostatic apex and the bottom of ischial tuberosities,the bottom of obturator foramen, the bottom of pubic symphysis and the bulb of the penis. The volume of prostate was calculated and the relationship between the size of the prostate and the localization of the prostatic apex was analyzed. Results The prostatic apex is located 13. 1 mm ±3. 3 mm superior to the bulb of the penis, 11.0 mm ± 5.4 mm superior to the bottom of obturator foramen, 31.3 mm ± 5.5 mm superior to the bottom of ischial tuberosities, and 7. 1 mm ± 4. 7 mm superior to the bottom of obturator foramen. There was no correlation between the size of prostate and the localization of the prostatic apex(R =0. 07、-0. 33, all P ＞ 0. 05). Conclusions Ninety-five percent of patients had a prostatic apex that is above the bulb of the penis 6 mm, and 100% of patients had a prostatic apex that is above the bottom of obturator foramen.

Objective:To compare the effects of three root canal sealers with respect to time on biocom-patibility of human periodontal ligament cells (hPDLCs).The sealers included zinc oxide and eugenol based sealers (ZOE),epoxy resin sealers (ERS)and silicone based sealers (SBS).Methods:hPDLCs were primarily cultured,with the method combining of tissue explant and enzymatic digestion.The cells were then exposed to different extract fluids:(1)ZOE extracted for 24 h group ;(2)ZOE extracted for 1 week group;(3)ZOE extracted for 2 weeks group;(4)ERS extracted after 24 h group;(5)ERS extracted after 1 week group;(6)ERS extracted after 2 weeks group;(7)SBS extracted after 24 h group;(8)SBS extracted after 1 week group;(9)SBS extracted after 2 weeks group;(10)Dulbecco modified Eagle’s me-dium/F12(DMEM/F12)as negative control group.Cell morphology was observed under an inverted mi-croscope.Cell proliferation was measured by methyl-thiazol-diphenyltetrazolium (MTT)assay.ALP assay kit was used for measuring alkaline phosphatase (ALP)activity.Sealers of 2 weeks’setting time were then immersed in an osteogenic medium for examination of mineral nodules and calcium deposits.Re-sults:Considering the relative growth rate (RGR),ZOE was severely to moderately cytotoxic (RGR:13.6% -39.9%),while ERS was slightly or not cytotoxic (RGR:87.6% -95.3%).Only SBS did not show any cytotoxicity after setting (RGR:91.8% -106.7%).The setting time influenced the cytotoxic-ity of ERS which decreased after 1 week.Considering the ALP activity,there was no difference between SBS group and control group(F =3.397,P =0.053).According to the results of calcium deposits, ZOE:D562 nm =0.180 ±0.050,ERS:D562 nm =2.968 ±0.201,SBS:D562 nm =3.623 ±0.039,Control:D562 nm =3.477 ±0.102,the ranking of ALP activity and calcium deposits was as follows:ZOE

Objective:To investigate the brain activation patten associated with visual sexual stimuli.Method:Thirteen healthy right-handed women were enrolled through advertisements on campus.They were scanned under functional magnetic resonance imaging(fMRI) when they watched emotional neutral films excepts and erotic films excepts.Statistic on theses data reveals the difference of brain activation.Result:The results showed that,compared to emotional neutral films,sexual visual stimuli were associated with the activation of a set of bilateral brain areas including lateral occipital cortex,postcentral gyrus,superior parietal lobule,occipital fusiform gyrus, hippocampus,and so on.Most activated brain areas are bilateral.Only in inferior frontal gyrus pars opercularis(Z=3.64,P<0.0001) and pars triangular(Z=3.42,P=0.003) there were significant right hemispheric activation.Conclusion:fMRI results indicate that inferior frontal gyrus is related to the visual sexual stimuli of women subjects,and is specified on the right hemisphere rather than left one.This sphere-special area may play an important role on sexual message processing.

OBJECTIVE:To investigate therapeutic efficacy and safety of levamlodipine and telmisartan combined with hydro-chlorothiazide in the treatment of anti-dipper hypertension. METHODS:Totally 150 patients with anti-dipper hypertension were ran-domly divided into group A,B,C,with 50 cases in each group. Group A was given Telmisartan tablet 40 mg+Hydrochlorothiazide tablet 10 mg,once a day,in the morning. Group B was given Levamlodipine tablet 5 mg,once a day,in the night. Group C was given Telmisartan tablet(usage and dosage same as group A)+Hydrochlorothiazide tablet(usage and dosage same as group A)+Le-vamlodipine tablet(usage and dosage same as group B). Treatment courses of 3 groups lasted for 8 weeks. The changes of electro-lyte and 24 h ambulatory blood pressure were observed and compared among 3 groups before and after treatment. The incidence of adverse reactions was recorded. RESULTS:There was no statistical significance in the electrolyte indexes in 3 groups before and af-ter treatment(P>0.05). Before treatment,there was no statistical significance in 24 h blood pressure among 3 groups(P>0.05). Af-ter treatment,the 24 h blood pressure of the patients in the 3 groups after treatment was lower than before treatment,and group C was lower than that of the group A and group B(P<0.05). After treatment,the rate of anti-dipper rhythm reversal in group C was significantly higher than group A and B,with statistical significance(P<0.05). There was no statistical significance in the inci-dence of ADR among 3 groups(P>0.05). CONCLUSIONS:Levamlodipine and telmisartan combined with hydrochlorothiazide show good therapeutic efficacy for anti-dipper hypertension,and can reduce 24 h blood pressure and effectively reverse anti-dipper rhythm with good safety.

Objective We retrospectively studied the MRI and MRA appearances of 10 patients,(6 children,4 adults) with Moyamoya disease.Methods MRI and MRA images were analyzed.For the MRA images,it was concerned that whether there were occlusive changes of the internal carotid artery and middle cerebral artery and whether there were collateral vessels.For the MRI images,the locations of the infarct lesions were studied.Results For the MRA images,the internal carotid arteries and the middle cerebral arteries were observed stenosis,and collateral vessels were formed in cerebral hemispheres.There were no remarkable differences between the children and adult groups with regard to the occlusive changes or to the flow void sign on MRA.However,Moyamoya disease in children exhibited a significant increase in the cortical and subcortical infarction(75%,9/12).In contrast,there were much more deep white matter infarctions in the centrum semiovale and basal ganglia in the adult group(87.5%,7/8)than in the children group(33.3%,4/12).Conclusion MRI and MRA are the method of choice in diagnosis of Moyamoya disease.The differences in the site of infarctions between the childhood and the adult Moyamoya disease observed on MRI may explain the differences in the clinical presentation.

OBJECTIVE:To explore the method and efficacy of occlusion with medicinal albumin gel for esophageal fistula. METHODS:Over the recent 5 years,a total of 11 patients with esophagus -respiratory fistula or esophagus-neck fistula confirmed by iodine imaging and / or gastroscopy were occluded with medicinal albumin gel under endoscope. RESULTS:The occlusion with medicinal albumin gel for esophageal fistula was successful in all the 11 cases,and 9 out of 11 were completely healed after one time occlusion treatment and the other 2 cases were completely healed after the second occlusion treatment. The average hospital stay was 27 days and the average cost was 24,500 yuan. There was no recurrence after follow-up of 3 to 6 months,nor was there any adverse complication. CONCLUSION:Compared to the conventional conservative treatment,occlusion with medicinal albumin gel for esophageal fistula under endoscope can reduce the length of hospital stay and the cost of hospitalization.
