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 study the effect of tannins from Pericarpium Granati on hepatic microsomal enzyme in rats. Methods:Thirty Wistar rats were randomly divided into five groups:the blank control group, high, medium and low dose groups of tannins from Pericarpium Granati, the positive control group of phenobarbital sodium. The blank control group was given physiological saline. The three different doses groups were respectively given tannins from Pericarpium Granati orally at the dose of 150,100 and 75 mg·kg-1 · d-1 for 7 days. The positive control group was given phenobarbital sodium 80 mg·kg-1 ·d-1 with intramuscular injection for 5 days. At the end of the experiment, the activity ofⅠandⅡphase metabolic enzymes in liver microsomes of each group was determined by UV. Results:Compared with the blank control group, the high, medium and low dose groups of tannins from Pericarpium Granati could sig-nificantly decrease the content of CYP 450 and CYPb5, and inhabit the activity of ADM (P<0. 01);the high and medium dose group could significantly inhibit ERD enzyme activity (P<0. 01);the high dose group could significantly reduce GST enzyme activity (P<0. 01). Conclusion:Tannins from Pericarpium Granati has notably inhibitory effect on hepatic microsomal enzyme in rats, which can reduce the expression of CYP3A and CYP2E1 in a dose-dependent manner.

Objective:To investigate the clinical application of fibrinogen (FIB) in a certain hospital to enhance the rational use in clinics.Methods:A retrospective investigation was adopted to analyze the clinical application of FIB in a certain hospital in 2016. Results:Totally 489 inpatients were treated with FIB in 2016,and among them,243 cases were surgery patients and another 246 ones were non-surgery patients. The main involved departments were cardiovascular surgery,cardiovascular medicine,emergency,intensive medicine,gynaecology and obstetrics, gastroenterology and neurosurgery. The rationality of indication was 80.0% (391/489), and the non-indication use mainly existed in cardiovascular surgery and cardiovascular medicine departments. Among the 391 cases with in-dication,3 cases were with improper compatibility,17 cases with low dosage, and the irrationality of usage and dosage was 17.9% (20/391). Conclusion:The clinical application of FIB is basically rational in the hospital,while non-indication use still exists during the perioperative period in cardiovascular and cerebrovascular surgery,and nonstandard usage and dosage appear in clinics from time to time. The prescription comment on blood products such as FIB should be enhanced in order to improve the rational use in clinics.

Objective:To investigate the therapeutic effect of tannins from pomegranate rind on passive Heymann nephritis ( PHN) in rats. Methods:Rabbits were with intradermal immunization for many times to obtain anti-Fx1A serum, and then PHN model in rats was established by tail intravenous injection of anti-Fx1A serum. The experimental rats were randomly divided into six groups, the nor-mal control group, model group, benazepril group, and tannins from pomegranate rind group respectively at high, medium and low dose. After the success of modeling, each rat was received intragastric administration for five weeks, and then the total of urine was collected once a week for the detection of 24-hour urine protein. At the end of treatment, serum was collected for the detection of serum albumin, blood urea nitrogen, creatinine, total cholesterol and triglyceride. The pathological changes of the renal tissue were observed using hematoxylin-eosin and Masson staining to observe the effect of tannins from pomegranate rind on PHN rats. Results:After the in-tragastric administration for five weeks, tannins from pomegranate rind could obviously reduce the level of 24-hour urine protein in PHN rats(P<0. 01), significantly reduce the levels of serum creatinine (P<0. 01), urea nitrogen (P<0. 01,P<0. 01,P<0. 05), total cholesterol (P<0. 01) and triglyceride (P<0. 01,P<0. 01,P<0. 05) in PHN rats, and increase the level of serum albumin (P<0. 01,P<0. 05,P>0. 05). HE and Masson staining results indicated that tannins from pomegranate rind could improve the pathologi-cal damage in PHN rats. Conclusion:Tannins from pomegranate rind has notable improvement for PHN in rats.

Objective:To study the effect of molecular weight and degree of substitution (DS) of chitosan-poly-arginine (CS-R9) on transdermal penetration enhancement in vitro. Methods:Low molecular CS, medium molecular CS or high molecular CS was respectively used to synthesize CS-R9 with different molecular weight (LCS-R9-1, MCS-R9 and HCS-R9). Low molecular CS was used to synthesize CS-R9 with various degree of substitution by changing the mole ratio between R9 and CS (LCS-R9-1, LCS-R9-2 and LCS-R9-3). The in vitro transdermal penetration enhancement of the different CS-R9 on tinidazole ( TNZ) was studied using Franz diffusion cells. Results:According to the results of FTIR and 1 H-NMR, a series of target CS-R9 were synthesized including LCS-R9-1 with the DS of 2. 30, MCS-R9 with the DS of 2. 17, HCS-R9 with the DS of 2. 20, LCS-R9-2 with the DS of 8. 05 and LCS-R9-3 with the DS of 15. 87. Compared with the blank control group, Azone group, LCS group, R9 group and LCS+R9 group, LCS-R9-1 could enhance the in vitro transdermal penetration of TNZ significantly (P<0. 05). When the DS was unchanged, LCS-R9-1 and HCS-R9 showed similar enhancement in the first 12h, and the effects were both higher than that of MCS-R9 (P<0. 05). The enhancement of HCS-R9 was decreased during 12-24h, while compared with that of LCS-R9-1, the difference was not notable (P>0. 05). When the molecular weight of CS was unchanged, the effect was increased with the rise of DS in the first 21h, however, after that, the effect was decreased with the rise of DS. Conclusion:Molecular weight and DS both have significant effect on the in vitro transdermal penetration enhancement of CS-R9, and it is valuable to further study the in vivo transdermal penetration enhancement of CS-R9 and underlying mechanisms.

Objective To investigate the indication and result of parental artery occlusion, embolization with coils, stents in treatment of the traumatic carotid artery pseudoaneurysm. Methods There were six patients with traumatic carotid artery pseudoaneurysm including three patients of cavernous pseudoaneurysm combined with carotid-cavernous fistula (CCF), two with simple traumatic carotid artery pseudoaneurysm and one with traumatic carotid artery pseudoaneurysm that was found after CCF embolization with detachable balloon. The treatment included balloon occlusion for CCF and traumatic carotid pseudoaneurysm in one patient, coil embolization in three and intenal carotid artery balloon occlusion in two. The Clinical manifestations, imaging data, choice of treatment, clinical efficacy, follow-up data and literatures were analyzed to discuss the indications for three treatments. Results There was no cerebral ischemia or surgically-related complication. No epistaxis occurred. The eyeball protrusion restoration was found in three patients and intracranial bruit vanishing in three. Vision was improved one patient after half a year follow-up. The pupils shrank in three patients during follow - up. Digital subtraction angiography (DSA) showed no recurrence of pseudoaneurysm. Conclusions Endovascular treatment is the preferred choice of treatment for traumatic carotid artery pseudoaneurysm. The occlusion or parent artery balloon occlusion can be used when the pseudoaneurysm is combined with CCF. Coil embolization can be used for shoes with narrow neck, stent technology combined with coil embolization for those with wide neck and the covered stent for the rock section of the internal carotid artery.

Polyamine biosynthesis is controlled primarily by omithine Decarboxylase (ODC) and S-adenosylmethionine decarboxylase (AdoMetDC). Antisense ODC and AdoMetDC sequences were cloned into an adenoviral vector (Ad-ODC-AdoMetDCas). To study the inhibitory effects of Ad-ODC-AdoMetDCas on polyamine biosynthesis and esophageal cancer cell apoptosis, adenovirus-mediated gene tmnsduction efficiency was assessed with counting GFP-positive cells using MTT. The malignant phenotype of Eca109 cells was assessed by growth curve. Western blot and HPLC were used to detect ODC and AdoMetDC expression and polyamine content in Ecal09 cells. TUNEL was used to analyze cell apoptosis. The change of morphology of apoptotic cells was observed by electron microscope. It was demonstrated approximate 70% of Eca 109 cells were infected with Ad-ODC-AdoMetDCas when MOI reached 50. The expression of ODC was inhibited in the infected tumor cells. Ad-ODC-AdoMetDCas could inhibit Ecal09 cell growth and invasive ability. TUNEL proved that Ad-ODC-AdoMetDCas can lead to cell apoptosis. Characterized morphology was observed by electronmicroscope (ehromatincondensation,nuclear disintegration,formation of apoptoticbodies).It was suggested Ad-ODC-AdoMetDCas has significant inhibitory effects on esophageal cancer cell proliferation, leads to cell apoptosis and bears therapeutic potential for the treatment of esophageal cancer.
