The fusion of cranio-jaw-facial CT and MRI image was obtained. It suggested that the fusion of cranio-jaw-facial CT and MRI image was feasible in clinical practice. It can provide the image basis helping the analysis of diagnosis and treatment for diseases of the cranio-jaw-facial region with complicated anatomical formation.

Objective To investigate the recurrence and influence factors of spontaneous pneumothorax in patients after thoracoscope surgery. Methods From March 2009 to March 2011,218 patients with spontaneous pneumothorax after thoracoscope surgery in our hospital were surveyed by the self-made general data questionnaire. The clinical data were analyzed by descriptive statistics and binary classification logistic regression analysis of SPSS 19. 0 to find out the infection influential factors of spontaneous pneumothorax for patients after thoraco-scope surgery in order to provide reference basis for reducing postoperative recurrence. Results The recurrence rate of spontaneous pneumo-thorax was 5. 05%(11/218). Multiple logistic regression analysis showed that recurrent pneumothorax ( OR=2. 432,P=0. 000) and multi-ple pulmonary bulla (OR=1. 918,P=0. 000) were the risk factors of spontaneous pneumothorax for patients after thoracoscope surgery. Conclusion The recurrence rate of spontaneous pneumothorax is high,we should strengthen the management of high-risk population and im-prove the prognosis of patients.

Objective To observe the change of serum smooth muscle myosin heavy chain (smMHC) level in the patients with aortic dissection (AD),and evaluate the effect of smMHC in the early diagnosis and prognosis of AD.Methods Forty-two patients with AD were selected as AD group,30 healthy subjects were selected as control group.Blood samples were collected at four time periods (within 3 h of onset,6 h,12 h,24 h),and serum smMHC level were measured by enzyme-linked immunosorbent assay.Results Serum smMHC level of AD group,which collected (within 3 h of onset,6 h,12 h) were significantly higher than that of control group [(88.6 ±21.7),(59.4 ± 18.7),(41.3 ± 10.7) ng/L vs.(17.2 ± 8.3) ng/L,P ＜ 0.01].There was no significant difference between the serum smMHC level of AD group and control group at 24 h after onset [(18.9 ±9.5) ng/L vs.(17.2 ±8.3) ng/L,P ＞ 0.05].Serum smMHC level of Stanford A type group (25 cases) was higher than that of Stanford B type group (17 cases) within 3 h of onset [(95.4 ± 17.8) ng/L vs.(78.5 ± 18.3) ng/L,P＜0.01],and there was no significant difference bewteen the two groups which collected at 6,12 h and 24 h after onset (P ＞ 0.05).Preoperative serum smMHC level was significantly higher than that after intracavitary isolation operation [(58.6 ± 15.9) ng/L vs.(30.1 ± 12.5) ng/L,P ＜ 0.01].Serum smMHC level decreased rapidly after the operation,and there was no significant difference between the two grougs when 12 h after operation [(18.7 ± 8.9) ng/L vs.(17.2 ± 8.3) ng/L,P ＞ 0.05].The serum smMHC level of the deaths (7 cases),which collected within 3 h of onset,6 h,12 h,was significantly higher than that of the survivors (35 cases) [(101.2 ± 20.7) ng/L vs.(86.1 ± 18.9) ng/L,(65.2 ± 16.7) ng/L vs.(58.2 ± 14.2) ng/L,(50.4 ± 10.8) ng/L vs.(39.5 ± 8.3) ng/L,P ＜ 0.05],and there was no significant difference at 24 h after onset (P ＞ 0.05).Detecting serum smMHC level within 3 h of onset,the area under the receiver operating characteristic curve was 0.913,with 51.7 ng/L as a diagnostic critical value,sensitivity and specificity respectively was 88.1％ (37/42) and 96.7％ (29/30).When detecting at 6 h after onset,the area under the curve was 0.865,with 38.5 ng/L as a diagnostic critical value,sensitivity and specificity respectively was 90.4％(38/42) and 90.0％ (27/30).Conclusions The level of serum smMHC in patients with AD increase rapidly after onset,and detecting serum smMHC level within 6 h of onset have important clinical significance in early diagnosis and prognosis of AD.

Objective To investigate the optimization of therapeutic regimen through the adjustment of the minimum sub-field area in intensity-modulated radiotherapy (IMRT) for cervical cancer,under the premise of no influence on the dose to target volume or organs at risk.Methods A total of 12 patients with pathologically confirmed cervical cancer were enrolled,and the prescribed dose to the planning target volume (PTV) was 50 Gy in 25 fractions.The Pinnacle 8.0m treatment planning system was used for all patients,and 16 IMRT plans were developed for each patient,with the application of 9 evenly distributed fixed incidence directions (0°,40°,80°,120°,160°,200°,240°,280°,and 320°),a minimum sub-field number of 80,and a minimum sub-field hop count (MU) of 5 MU.The range of sub-field area was 2-81 cm2.Direct machine parameter optimization was used for inverse-planned optimization calculation,and all the plans met the requirements of the clinical prescribed dose.The dose-volume histogram was used to evaluate the dose distribution in target volume and organs at risk.Results With the sub-field area increasing from 2 cm2 to 81cm2,the total hop count of IMRT plan was reduced from (1405±170) MU to (490±47) MU (P=0.000),and when the sub-field area increased above 6 cm×6 cm,the total hop count was reduced significantly (P=0.000).In the IMRT plan with a minimum sub-field area of 2-49 cm2,there was no significant difference in dose between the target volume and the organs at risk (P＞0.05).The dose to the rectum,the bladder,and both femoral heads showed no significant differences across the IMRT plans with different minimum sub-field areas (P＞0.05).Conclusions When the Pinnacle 8.0m treatment planning system is used to develop IMRT plans for cervical cancer,the requirements for clinical dose can still be met with a minimum sub-field area reaching 7 cm×7 cm,and there are significant reductions in sub-field hop count and total hop count.

OBJECTIVETo study the therapeutic effects and mechanism of Jiechangning (JCN) decoction on carrageenan induced experimental ulcerative colitis (UC).

METHODSAfter sensitizing guinea pigs with carrageenan, we established UC animal models by free drinking water containing 2% acid degraded carrageenan (ADC). JCN decoction was orally administered once a day for 2 weeks after carrageenan treatment. Salicylazosulfapyridine (SASP) and normal saline were given to the other two groups as control. The levels of colon lipid peroxide (LPO), acid phosphatase (ACP) activity and tumor necrosis factor-alpha (TNF-alpha) were measured; colitis activity score (CAS) was carried out for assessment of the degree of tissue inflammation and injury; the colonic pathological changes were examined simultaneously with hematoxylin and eosin (HE) and toluidine blue staining used to evaluate the therapeutic effects of JCN decoction and SASP.

RESULTSExperimental colitis models resembling human UC were successfully induced. The levels of tissue LPO, ACP activity and the content of tissue TNF-alpha were markedly increased in the model group as compared with the normal control group (P < 0.01) and were positively correlated with CAS. JCN decoction could reverse these changes like SASP. HE staining showed that JCN decoction and SASP could reduce CAS and the degree of tissue injury, toluidine blue staining revealed that mucosa and submucosa red metachromasia pellets in JCN group and SASP group were markedly fewer than those in the model group.

CONCLUSIONJCN decoction is effective in treating experimental UC, which provides theoretical basis for its clinical application.
