Objective To explore the effect of secondary brain injury(SBI) in high-risk factors and brain malignant encephaiocele during surgical operation for severe traumatic brain injury. Methods Carried on the grouping graduation to 112 patients with severe traumatic brain injury according to SBI's high-risk factors:non-high-risk factors group (pure group) 23 cases, high-risk factors group (SBI group) 89 cases, 1 level of high-risk factors group had 27 cases, 2 level of high-risk factors group had 28 cases, 3 level of high-risk factors group had 34 cases. Results Carried on the comprehensive therapy regarding the above patients, the brain malignant encephalocele rate in the SBI group and the pure group was 59.55% (53/89) and 13.04%(3/23) respectively, there was significant statistics differences in the two groups,1 level and 2 level of high-risk factors group of brain malignant encephalocele rate was 40.74% (11/27) and 53.57% (15/28) respectively, the difference was not obvious statistics significance, 2 level and 3 level of high-risk factors group of brain malignant eneephalocele rate was 53.57%(15/28) and 79.41%(27/34) respectively, the difference was obvious statistics significance. Conclusions The SBI's high-risk factors are the important factors affecting severe craniocerebral injury encephalocele. Taking adequate pre-operative assessment, carrying a comprehensive treatment on the patients combine with high-risk factors of SBI can greatly reduced the incidence of brain malignant encephalocele during surgical operation if the high-risk factors of SBI is controlled.

The judgment of early curative effect is important to the treatment of nasopharyngeal carcinoma and the prognosis of the patients.As a rapid imaging technique,magnetic resonance diffusion weighted imaging (DWI) is used to quantitatively analyze the changes of water molecules in the tissue by means of apparent diffusion coefficient (ADC),so as to diagnose the small lesions of nasopharyngeal carcinoma accurately,evaluate the early curative effect and observe the prognosis.With the continuous improvement and progress of MRI and data analysis technology,DWI in the diagnosis and treatment of nasopharyngeal carcinoma shows a broader application prospect.

Objective:To study the risk factors affecting the prognosis of patients with type Ⅰ endometrial cancer.Methods:A total of 279 patients with type Ⅰ endometrial cancer admitted to the First Affiliated Hospital of Southwest Medical University were enrolled from January 2010 to January 2015. The clinical data of all patients were retrospectively analyzed. The Kaplan-Meier method was used to estimate patients′ survival rate. Cox regression risk model was used to analyze the risk factors that might affect the prognosis of patients with endometrial cancer.Results:Of 279 patients with endometrial cancer, postoperative recurrence was observed in 36 patients. The 5-year disease free survival rate was 87.10%(243/279). The 2, 3 and 5-year survival rates were 95.9% (95% CI: 93.6%-98.3%), 94.3% (95% CI: 91.6%-97.2%), and 90.4% (95% CI: 86.6%-94.3%). Univariate analysis showed that obesity ( HR=2.194, 95% CI: 1.031-4.671, P=0.041), myometrial invasion ( HR=2.957, 95% CI: 1.382-6.329, P=0.005), tissue grading (G2: HR=3.271, 95% CI: 1.336-8.010, P=0.010; G3: HR=9.933, 95% CI: 3.565-27.672, P<0.001), tumor size ( HR=8.067, 95% CI: 2.426-26.821, P=0.001), abdominal cytology ( HR=3.293, 95% CI: 1.523-7.121, P=0.002), surgery-pathological staging (Ⅲ stage: HR=28.357, 95% CI: 11.516-69.828, P<0.001), nature of lymph node ( HR=14.629, 95% CI: 5.023-42.606, P<0.001), cervical interstitial infiltration ( HR=3.806, 95% CI: 1.653-8.764, P=0.002), accessory metastasis ( HR=9.101, 95% CI: 3.831-21.622, P<0.001) and lymphovascular space invasion ( HR=5.011, 95% CI: 2.233-11.249, P<0.001) were all correlated with the prognosis of the patients. Multivariate analysis showed that the independent risk factors for the prognosis of endometrial cancer patients were depth of myometrial invasion ( HR=2.503, 95% CI: 1.115-5.616, P=0.026), histological grading (G2: HR=3.143, 95% CI: 1.205-8.198, P=0.019; G3: HR=3.655, 95% CI: 1.151-11.610, P=0.028), surgery-pathological staging (Ⅲ stage: HR=27.701, 95% CI: 9.608-79.869, P<0.001) and lymphovascular space invasion ( HR=3.297, 95% CI: 1.370-7.936, P=0.008). Conclusion:Obesity, myometrial invasion, tissue grading, tumor size, abdominal cytology, surgery-pathological staging, nature of lymph node, cervical interstitial infiltration, adnexal metastasis and lymphovascular space invasion all affect the prognosis of patients. Depth of myometrial invasion, histological grading, surgical-pathological staging and lymphovascular space invasion are independent risk factors for the prognosis of patients with Ⅰ endometrial cancer.

Objective To explore the application value of emergency temporal body surface positioning for single drain dual-target thalamic hematoma ventricular drainage in the treatment of thalamic hemorrhage breaking into ventricle with hydrocephalus.Methods A retrospective analysis was conducted on 223 patients with thalamic hemorrhage breaking into the ventricles with hydrocephalus,including a study group of 115 cases who underwent emergency single drain dual-target thalamic hematoma ventricular drainage surgery with temporal body surface positioning,and a control group of 108 cases who underwent emergency ventricular drainage first and then underwent stereotactic thalamic hematoma drainage surgery after the condition stabilized.Compare the differences in postoperative complications and treatment outcomes between two groups of patients,and evaluate the application value of temporal surface positioning for single drain dual-target thalamic hematoma ventricular drainage surgery in the treatment of thalamic hemorrhage breaking into the ventricle with hydrocephalus.Results The postoperative rebleeding rates,hematoma clearance and death were 5.2％,87.5％±7.3％and 13.9％in the study group and 4.7％,90.2％±8.5％and 15.7％in control group,respectively.There was no significant difference between the two groups(P＞0.05).The tube time,postoperative intracranial infection,Shunt dependent hydrocephalus,effective treatment and favorable prognosis of and the control group were(75.5±18.4)h,3.5％,19.1％,53.9％and 51.3％in the study group and(130.8±22.9)h,13.9％,35.1％,38.7％and 38.0％,respectively.The difference between the two groups was statistically significant(P＜0.05).Conclusion Body surface landmark-guided emergency single drain dual-target thalamic hematoma ventricular drainage surgery for the treatment of thalamic hemorrhage breaking into the ventricle with hydrocephalus is safe and reliable,and can improve the patient's prognosis.

Objective To study the compliance of forbidden depasturing livestock on the marshland with Oncomelania snails in schistosomiasis endemic areas. Methods According to 3 levels of human infection rates as > 10% ,5%-10% and <5% , 2 204 residents selected randomly from the schistosomiasis endemic villages were sampled with the stratified cluster sampling method in Hunan, Hubei, Jiangxi, Anhui, Jiangsu, Sichuan and Yunnan provinces, and investigated by questionnaire. The contents of the questionnaire included the recognition and implementation of forbidden depasturing livestock on marshland with Oncomelania snails and breeding livestock in bam. Results A total of 78.4% residents agreed forbidden depasturing livestock on marshland with snails, but 3. 7% residents disagreed it. A total of 83. 9% residents considered the relationship between breeding livestock in bam and schistosomiasis control, but 3. 1% residents thought that it was no relationship. The main reasons of depasturing livestock on marshland with Oncomelania snails were the high cost of breeding livestock in bam (36. 2% ) , unaccustomed (26.4% ) and no room for breeding livestock in bam (25.4% ). Conclusion Forbidden depasturing livestock on the marshland with Oncomelania snails should be strengthened according to the local economic, nature environment, agriculture, residents'culture degree and agriculture habit.

Endovascular mechanical thrombectomy (EMT) has become the main treatment of acute ischemic stroke, but the pathological study of thrombi retrieved with EMT is still very limited. This article reviews the routine staining, special components, expression of immune factors, electron microscopic morphology, imaging features of the pathological components of thrombi retrieved with EMT, and their correlation with the etiological differentiation and outcomes of stroke.
