Endometrial cancer is one of the malignant tumors of female reproductive system. The prognosis of advanced endometrial cancer is poor. How to improve the overall survival rate and improve the prognosis of patients with advanced endometrial cancer is still one of the clinical problems. In recent years, the research on tumor gene changes is increasing gradually. Epigenetics is the study of genetic changes in gene expression without changing the nucleotide sequence of genes. Epigenetics includes many phenomena, such as DNA methylation, microRNA expression and gene silencing, chromatin remodeling. These changes may be important factors in the occurrence and development of tumors, and may become new therapeutic targets for tumors. With the study on epigenetics of endometrial cancer in the future, new therapeutic targets may be found. Meanwhile, those study may provide new ideas for targeted therapy of endometrial cancer.

ObjectiveTo study the method and effect of individualized education on children with learning disability (LD).Methods30 children during 7-10 year old in a local boarding elementary school were chosen and guided individually as the following: sensory integration dysfunction drill, subtle motion drill, life skills drill, cognitive capability drill, behavior therapy, game therapy, music therapy and parents education. One and a half year later, the index of Sensory Integration Rating Scales and study marks were determined and compared with that of the normal children.ResultsThere is not significant difference between the LD children and the normal ones in the sensory integration of behavior and the learning achievement.ConclusionIndividualized education is a valid approach improving the potentiality of the LD children\'s physiology and psychology.

Objective To study the effects of Xuanbaichengqi decoction on the regulation of inflammatory factors TNF-α and IL-1 β in patients with acute respiratory distress syndrome (ARDS) and its mechanism.Methods 60 patients with ARDS who had been hospitalized from January 2016 to August 2016 were randonly selected and then assigned to a control group (30 patients) and a study group (30 patients).Both groups received routine therapies and mechanical ventilation,and the study group received additional Xuanbaichengqi decoction.Levels of TNF-o,IL-1β and IL-10,and peak inspiratory pressure (PIP),plateau airway pressure (Pplat),PVC,forced vital capacity (FVC),forced expiratory volume in one second (FEV 1),and oxygenation index (PaO2/FiO2) were detected before and after treatment.Results Levels of TNF-α and IL-1βwere significantly lower in the study group than in the control group (P ＜ 0.05).IL-10 level was significantly higher in the study group than in the control group (P ＜ 0.05).And the improvement in PIP and Pplat was also significant in the study group (P ＜ 0.05).Less adverse reactions occurred in the study group.Conclusions Xuanbaichengqi decoction can improve the indexes for respiratory mechanics and pulmonary function in patients on mechanical ventilation and reduce the inflammatory response,having a significant effect.

Objective To investigate the clinical value of 99m Tc-HL91 hypoxia imaging in the diagnosis and treatment of lung cancer. Methods 99m Tc-HL91 hypoxia imaging was performed in 72 patients with primary lung cancer. The qualitative analysis and semi-quantitative analysis of the early and delayed images were also performed. 65 patients underwent chemotherapy were divided into 2 groups by the T/N value of delayed images, and the curative efficacy in both the two groups was compared. Results The sensitivity of 99m Tc-HL91 hypoxia imaging for diagnosing lung cancer was 86 1% in early imaging and 98 6% in delayed imaging. The results of semi-quantitative analysis in different pathological types of lung cancer hadn’t obvious difference. The curative efficacy of the patients with low uptake was better than that of the patients with high uptake in 65 patients underwent chemotherapy, difference of which had significant(P

ObjectiveTo investigate the effect of dexmedetomidine pretreatment on focal cerebral ischemia-reperfusion(I/R) injury in rats.MethodsOne hundred male SD rats weighing 290-310 g were randomly divided into 5 groups(n =20 each):sham operation group(group SH) ; focal cerebral I/R group; focal cerebral I/R + dexmedetomidine 100 μg/kg(group L); focal cerebral I/R+ dexmedetomidine 200 μg/kg (group M) and focal cerebral I/R + dexmedetomidine 400 μg/kg(group H).Focal cerebral I/R was produced by occlusion of middle cerebral artery for 60 min followed by 24 h of reperfusion.Dexmedetomidine 100,200 and 400 μg/kg were injected intraperitoneally 15 min before ischemia in groups L,M and H respectively.While equal volume of normal saline was injected intraperitoneally in group SH.Neurologic function was assessed and scored at 24 h of reperfusion.Then the animals were sacrificed and brains were removed for determination of cerebral infarct volume and microscopic examination.The expression of heat shock protein 70(HSP70) and activity of Na+ -K + -ATPase in ischemic cortex and activity of SOD and concentration of cortisol in plasma were determinationed at 24 h of reperfusion.ResultsCompared with group SH,neurologic deficit scores and plasma concentration of cortisol were significantly increased,activities of SOD and Na+ -K+ -ATPase decreased and expression of HSP70 was up-regulated in groups I/R,L,M and H( P ＜ 0.05).Compared with group I/R,neurologic deficit scores and plasma concentration of cortisol were significantly decreased,activities of SOD and Na+ -K+ -ATPase increased and expression of HSP70 was up-regulated in a dose-dependent manner ( P ＜ 0.05),and the pathological change was reduced in a dose-dependent manner in groups L,M and H.ConclusionDexmedetomidine pretreatment can attenuate focal cerebral I/R injury in a dose-dependent manner through improvement of brain cell energy metabolism and reduction of lipid peroxidation and stress reaction.

Objective To evaluate our short term results in endovascular treatment of symptomatic vertebral arteral stenosis with stents. Methods Balloon expanded stents were utilized to pass across the vertebral arterial stenosis, and then the balloons were inflated for the deployment of stents, outcoming with restoration of the stenosis to normal size. Results Forty five patients presented with posterior circulation ischemic symptoms and refractory to medical therapy were undertaken with endovascular stenting, showing technically successful in forty three of them. The mean degrees of preoperative and postoperative stenosis were 75.7% and 10.3%, respectively. Follow up data showed disappearence of clinical symptoms in 35 patients, chinical implovement and stabilization in 2. There were no intimal dissection and distal embolization. Short term follow up angiogram revealed no restenosis and intimal hyperplasia. Conclusions Endovascular stenting may be a favorable alternative for the treatment of vertebral arterial stenosis, but long term follow up is necessary.

Purpose: To study the clinical application of intensity modulation radiation therapy (IMRT) in patients with prostate cancer. Methods: From May 2000 to June 2001, 14 patients with prostate carcinoma were treated . 12 patients underwent orchiectomy before IMRT. All patients were treated by IMRT with PEACOCK-MIMiC system ( CORVUS 3. 0 NOMOS CORPORATION) and VARIAN 6MV-photons. The prescription dose-time- fraction was 2.5 to 3. 0 Gy per fraction, 5 times per week , the total was 25 to 30 fractions, the total IMRT dose was 72 to 77 Gy, 5 to 6 weeks. Results: 3 months after IMRT , PR: 10(71.4%), NC: 4 cases and 6 month after IMRT CR: 6,PR: 8 cases. The overall response( CR + PR) rate were 100% . No Grade Ⅲ ,Ⅳ gastrointestinal ( GI) and genitourinary ( GU) toxicity occurred in any of the patients. Conclusions: IMRT is an effective approach for patients with prostate carcinoma. The dose of 72 to 77 Gy was safe.
