Objective To investigate the difference between the self-evaluation of patients with dental and facial esthetics in skeletal malocclusion and normal persons.Methods The subjects were divided into three groups:62 patients with skeletal Class Ⅱ,84 patients with skeletal Class Ⅲ,as well as 130 persons in control group.There was no obvious difference in gender and age among the three groups.Happiness with dental and facial appearance was assessed using questionnaires.Analysis of variance,linear regression and logistic regression were used for statistical analysis.Results Skeletal malocclusion patients were less happy with their dental appearance than control group.Class Ⅱ patients and women had lower happiness scores for their dental appearance.Among skeletal malocclusion patients,the shape (44.5 ％) and prominence of their teeth (17.8 ％) were the most frequent causes of concern.Older subjects,women,and skeletal malocclusion patients were less happy with their facial appearance.Most of them were dissatisfied with the facial appearance focused on the chin (53 ％),facial contours (37 ％),and the position of the teeth when smiling (33 ％).A greater proportion of Class Ⅲ subjects than Class Ⅱ subjects wished to change their appearance.Conclusions The findings indicate that women and skeletal malocclusion patients have lower levels of happiness with their dentofacial appearance.Although Class Ⅱ patients exhibit the lowest levels of happiness with their dental appearance,there is some evidence that concerns and awareness about their facial profile are more pronounced among the Class Ⅲ patients.

Objective To study effect of general anesthesia combined with epidural anesthesia on analgesia and microcirculation in patients undergoing total hysterectomy. Methods 92 patients of total hysterectomy who received therapy were selected, according to random number table,those patients were divided into the observation group (n=42) and the control group (n=48),the observation group received general anesthesia combined with epidural anesthesia, the control group were only given general anesthesia.The operation condition, hemodynamics and stress response before anesthesia(T0), at tracheal intubation(T1), after pneumoperitoneum 10min(T2), after surgery(T3), at extubation(T4) were compared,and postoperative pain (VAS) score was compared. Results There was no significant difference in operation time and fluid volume between the two groups. In the control group,the levels of mean arterial pressure (MAP), heart rate (HR) at the time of T1, T2, T3 were significantly increased(P<0.05), the levels of MAP and HR at the time of T1,T2,T3 in the observation group were lower than the control group(P<0.05). The cortisol (Cor), epinephrine (E), norepinephrine (NE) at the time of T1,T2,T3,T4 in the observation group were lower than the control group(P<0.05). Two groups of patients in the postoperative 12h, 6h, the VAS scores in the resting state and cough state were higher than the postoperative 1h(P<0.05),but the scores in the observation group were lower than the control group(P<0.05). Conclusion General anesthesia combined with epidural anesthesia is well for total hysterectomy,which can maintain hemodynamic stability during surgery, relieve stress reaction, alleviate postoperative pain, it is worthy of application and promotion.

Objective:To investigate involvement of the Ras/Erk signal pathway in activation of human ??T cells stimulated by Mycobacterium tuberculosis low molecular peptide antigen(Mtb-Ag).Methods:PBMC were isolated from peripheral blood of healthy subjects and simulated in vitro with Mtb-Ag,CD3mAb or PMA and inomysin(IM).CD69 expression of total T cells and ??T cells were measured by flow cytometry at different hours after stimulation, and the number of expanded ??T cells were counted after 10 days of culture. PD98059,a specific inhibitor for Erk pathway was used to treat PBMC for 30 min before stimulation.Results:The proportions of CD69 expressing cells in total T cells and ??T cells were same as 99% at 6 h after stimulation of PBMC with PMA +IM and similar about 55% at 24 h after stimulation with CD3 mAb,whereas those at 24 h stimulation of PBMC with Mtb-Ag were 75.2% and 16.0%,respectively.CD69 expression and proliferation of ??T cells activated by Mtb-Ag were markedly inhibited by pretreatment of PBMC with PD98059.Conclusion:Mtb-Ag is a specific stimulator for activation of ??T cells, and Ras/Erk signal transduction pathway involves in the activation of ??T cells.

Objective To present the diagnosis and treatment of functional bladder outlet obstruction and to assess the results of transurethral bladder neck incision and alpha-blockers with regard to symptoms and urodynamic findings. Methods From October 1995 to October 2002,39 male patients (age range from 24 to 48 years,with a mean of 37 years) who had dysuria and underwent urodynamic examination,cystourethrography and urethral exploration were diagnosed with functional bladder outlet obstruction.The mean IPSS was 22.5.The mean maximum urinary flow rate was 10.2 ml/s and the mean residual volume was 124 ml.All the patients were treated with transurethral incision of bladder neck and alpha blockers. Results The mean operative duration was 15 min;mean blood loss was 50 ml;mean postoperative hospital stay was 3.5 d.During 1-year follow-up,most of the patients were satisfied with the treatment results.Subjective assessment showed a statistically significant reduction of the voiding complaints.The mean IPSS was 10.1 .The mean maximum urinary flow rate was 22.1 ml/s (range,12.7 to 42.1 ml/s) and the mean residual volume was 49 ml (range,0 to 84 ml). Conclusions Urodynamic examination,voiding cystourethrography and urethral exploration with dilator facilitate the diagnosis of functional bladder outlet obstruction.Treatments with transurethral incision of the bladder neck and alpha-blockers are effective and safe for functional bladder outlet obstruction.

Objective To compare the difference of dosimetric results between 3-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) with 5-field for thoracic middle esophageal carcinoma.Methods Ten patients with thoracic middle esophageal carcinoma were involved in this study.Four treatment plans were designed for each patient,including one 3D-CRT plan and three IMRT plans with 5-field and all evaluation contents were compared.Results There were no significant differences of cord Dmax,total-lung mean dose (Dmean),L-lung Dmean and R-lung V25,V30.Significant differences of heart V30,V40 and Dmean were obtained among the plans,with the lowest of 5IMRT2 (V30:28.67±15.97,V40:13.04±7.28,Dmean:2097.76±718.26) and 5IM RT3(27.39±14.96,13.00±7.32,2096.16±718.85),the highest of 5CRT (43.27±18.69,26.83±19.18,2393.48±896.12) and 5IMRT1 (41.81±17.16,23.08±11.17,2403.77±834.73).There were significant differences of L-lung V5,V10,V15,V20 V25 and V30.All IMRT plans reduce V20,V25 and V30.5IMRT1 did not increase V5 (54.39±7.58) and V10 (44.76±6.30),but reducesd V15 (20.86±5.16),5IMRT2 (V5:70.89±7.95,V10:50.94±8.71,V15:34.20±6.62) and 5IMRT3 (V5:70.26±7.94,V10:49.80±7.62,V15:34.60±5.40)increased V5,V10 and V15.There were also significant differences of R-lung V5.V10,V10,V20 and Dmean.All IMRT plans reduced V20,but increased Vs and V10.5IMRT1 did not increase V15 (23.67±5.73) and Dmean (923.49±182.34); 5IMRT2 did not increases V15 (26.72±±6.79) but increases Dmean (1060.34±205.02); 5IMRT3 increased both V15 (32.40±6.59) and Dmean (1100.54±197.84).Significant differences were found in Dmean,homogeneity index (HI) and conformity index (CI) of PTV,with the best Dmean of 5IMRT1 (6219.80±37.90),the second of 5IMRT3 (6268.91±56.26); the best HI of 5IMRT1 (0.0870±0.0219) and 5IMRT3 (0.0990±0.0219);the best CI of 5IRT2 (0.8682±0.0172) and 5IMRT3 (0.8667±0.0183).Conclusion 5-field IMRT plans have the advantages in the treatment of thoracic middle esophageal carcinoma with better HI,CI of target volume and sparing of lung (V20,V25 and V30) compared to 3D-CRT.5IMRT1 plan has the advantages in reducing low-dose volume (V5,V10,V15 and Dmean) of lung.

Objective To study factors influencing injury severity of expressway traffic acci- dents. Methods Data of expressway traffic accidents involving casualties in areas around Hangzhou during 2005-2006 were collected and analyzed by non-conditional simple and multiple logistic regression analysis. Results (1) During 2005-2006, there were 220 traffic crashes involving 327 eases, of which there were 64 deaths (19.6%), 121 severe injuries (37.0%, ISS≥16 points) and 142 slight and mod- erate injuries (43.4%, 1 point≤ ISS≤15 points). (2) Non-conditional simple logistic regression analy- sis showed that risk factors significantly influencing the injury outcomes of traffic accidents included gen- der, weekday, weather, type of collision, vehicle type, driver category, purpose of vehicle use, purpose of travel and crash responsibility. (3) Non-conditional multiple logistic regression analysis manifested that influential factors were gender, type of collision, driver category and crash respensibihty. Conclu- sion Analysis of expressway traffic accidents data helps identify factors influencing injury severity of ex- pressway traffic accidents may provide suggestions for prevention or decrease of expressway traffic acci- dents.
