Objective To explore the relationship between job burnout feeling and sleep quality in psychiatric female medical staff.Methods 100 female medical staff were randomly selected from two mental hospitals in Wenzhou,and the Pittsburgh sleep quality index was used to evaluate and Maslach burnout inventory;and the relation-ship between sleep quality and job burnout was analyzed.Results Female psychiatric and medical personnel to the personality dimension score was (10.84 ±4.75)points,which was higher than Maslach norm (7.12 ±5.22)points;emotion exhaustion scores of (14.44 ±6.38)points,low achievement sense score of (15.07 ±6.89)points,below the Maslach often die emotion exhaustion scores of (22.19 ±9.53)points and low achievement sense scores (36.54 ± 7.34)points.The differences were statistically significant (t =-12.15,7.84,-31.15,all P <0.01).Job burnout and there were significant correlations between sleep quality and the emotional exhaustion and personification and PQSI seven dimensions and the total score was a positive correlation,low sense of achievement and PQSI total score and negatively correlated with seven dimensions.Conclusion Wenzhou psychiatric female medical staff burnout is significantly higher than the general population,there is a correlation between staff burnout and sleep quality,and the more serious burnout,poorer quality of sleep.Improving the quality of sleep of medical staff is one of the ways to relieve job burnout.

Objective To study long-term outcome and prog nostic factors of esophageal squamous cell carcinoma patients treated by three dimensional conformal radiation therapy (3DCRT). Methods 169 patients with unresectable esophageal squamous cell carcinoma treated by 3DCRT were enrolled in the study. The survival rates of 1 year, 3 years and 5 years were estimated by life-table method. Univariate prognostic factor was tested by Log-rank method. Multivariate prognostic factor was analyzed by Cox model. Results The 1 year, 3 years and 5 years survival rates were 63.2%, 34.1%and 21.3%, respectively. Univariate analyses showed that the length of tumor, the site of lesion, chemotherapy, the dose of plan gross tumor volume (PGTV) and the short-term outcomes after treatment were the important prognostic factors for the long-term survival (P< 0.05), and multivariate analyses showed that the length of tumor, chemotherapy and the short-term outcomes after treatment were the independent prognostic factors for the long-term survival (P< 0.05). Conclusions The patients with unresectable esophageal squamous cell carcinoma treated by 3DCRT have a good long-term prognosis. The length of tumor, chemotherapy and the short-term outcomes after treatment are the important prognostic factors for the long-term survival of the patients. Chemotherapy can improve the long-term prognosis significantly.

Objective To evaluate the efficacy and safety of 650 nm,810 nm diode laser on the treatment of moderate to severe acne.Methods A total of 87 patients with moderate to severe acne were divided into diode laser group (group A) and medication group (group B).In group A,the patients were irradiated with 650,810 nm diode laser at the fluence of 400-450 mW distance of 2-3 cm.In group B,the patients were treated with roxithromycin combined with vitamin B6 and gel lincomycini.Clinical follow-up was performed every week for 4 months.All the adverse effects were recorded.Results There was no significantly statistical difference in the cure rate between the two groups (group A versus group B at 2 weeks:65.0 ％ versus 42.6 ％,P＞0.05; at 4 weeks:92.5 ％ versus 76.5 ％,P＞0.05).However,the recurrence rate of group A was much lower than that of group B (30.0 ％ versus 61.7 ％,P＜0.01).There were no severe adverse effects in both groups during the period of the follow-up.Conclusions Compared to the medication,650,810 nm diode laser appears to be associated with lower recurrence rate in the treatment of moderate to severe acne.

Objective To analysis of the efficacy and toxicity of multiple primary cancer of esophagus in three-dimensional conformal radiotherapy and concomitant chemotherapy.Methods Fifteen cases of multiple primary carcinoma of esophagus who refused the operation were collected.The Elekta linac 6 MV/10 MV X ray was used to conformal irradiation in three-four coplanar wild,2 Gy/time,1 time/day,5 times/week.The dose to the target area,CTV 40-50 Gy/4-5 weeks,GTV 60 Gy/6 weeks.TP scheme (paclitaxel+cisplatin) was used in the first day and 29th day,three-dimensional conformal radiation therapy initiated in the second day after chemotherapy.Results 1,3 year local control and overall survival were 86.7 ％ (13/15),33.4 ％ (5/15) and 73.3 ％ (11/15),26.6 ％ (4/15).Class 1-2 and class 3-4 acute radiation esophagitis and leukopenia occurred rates were 86.7 ％ (13/15),13.3 ％ (2/15) and 80 ％ (12/15),20 ％ (3/15).Conclusion Radiation therapy is the better treatment method for multiple primary carcinoma of esophagus when proximal lesions located in upper thoracic and cervical high.Toxic and side-effects can be tolerated of three dimensional conformal radiation therapy combined with chemotherapy in the treatment of multiple esophageal cancer.

To overcome the present limitations of passive biochip, based on the basic principle of antigen-antibody reaction, we develop an antigen-antibody reaction model of solid-phase surface and design a novel active biochip system according to this model, which introduces the negative pressure and controlling devices to control the immunoreactions on the nitrocellulose (NC) membrane. From the computer simulation results, this is a rapid, stable, robust and practicable system, which can be used to increase the efficiency of immunoreactions and improve the reproducibility and accuracy of biochip analysis.

Objective To study the expressions of P53,vascular endothelial growth factor (VEGF) and proliferating cell nuclear antigen (PCNA) in astrocytomas and their relationships with prognosis of these patients.Methods Immunohistochemical SP method was employed to detect the P53,VEGF and PCNA expression in 126 cases of human brain astrocytomas of different grades,collected in our hospital from May 2002 to May 2010; their correlations and their significance in the prognosis in these patients were analyzed.Results P53,VEGF,and PCNA expressed differently in astrocytomas of different grades,enjoying a positive relation with grades (P＜0.05); positive correlations of between P53 expression and both VEGF and PCNA expressions (r=0.608,P=0.000; r=0.432,P=0.001).In patients with the same grade of astrocytoma,those having positive P53 expression enjoyed poorer prognosis and lower survival rate with significant difference (P＜0.05); while VEGF and PCNA expressions had no correlation with the progonosis.Conclusion The expressions of PCNA,VEGF and P53 are closely associated with grade of the astrocytomas,and only P53 expression is an indicator of poor prognosis.

Objective To analyze set-up errors for irradiation of nasopharyngeal carcinoma by using kilo-voltage cone beam computed tomography (kV-KBCT) scanning, and to calculate the external margin from planning target volume (PTV) of nasopharyngeal carcinoma. Methods A total of 150 nasopharyngeal carcinoma patients in Meizhou People's Hospital from December 2014 to November 2016 were treated by image-guided radiation therapy (IGRT), kV-KBCT, CT image scanning matcthed by bone and grey alignment. PTV of nasopharyngeal carcinoma was also calculated. Results According to PTV formula, the external distance before radiotherapy guided by grey alignment was 0.5 mm in X-axis, 0.4 mm in Y-axis, 0.8 mm in Z-axis. While the distance was 0.1 mm in X-axis, 0.5 mm in Y-axis, 1.7 mm in Z-axis guided by bone alignment. After radiotherapy, the external distance guided by grey alignment was 0.4 mm in X-axis, 0.5 mm in Y-axis, 0.9 mm in Z-axis. While the distance was 0.1 mm in X-axis, 0.9 mm in Y-axis, 2.0 mm in Z-axis guided by bone alignment. There was no significant difference in set-up errors of 3 directions and 2 aligned ways before and after treatment.Conclusions The PTV within 3 mm is safe when IGRT is used for directing radiotherapy of nasopharyngeal carcinoma,and kV-KBCT is an effective image equipment.
