Results:The correlation coefficient (r)values between GT and BT at 2,4 and 6 mm below alveolar crest were 0.493,0.383 and 0.342 (P <0.001 )respectively,the r value between GT and the distance from CEJ to alveolar crest was -0.21 3(P <0.01 ).No statistically significant difference was observed between CBCT and clinical measurements(t =-0.521 ,P =0.603).Conclusion:There is positive correlation between GT and BT at 2,4 and 6 mm below alveolar crest and negative relation between GT and the distance from CEJ to alveolar crest.

Objective To explore the method and effect of computer simulative model of lying-in women in the teaching of gynecological nursing. Methods We separated 171 nursing students in grade 2005 into the control group (85 students) and the experimental group (86 students). For the experimental group the teaching method of computer simulative model of lying-in women was used. For the control group we used the traditional teaching method. The effects of two teaching methods were compared. Results The examination achievement of the experimental group was more than that of the control group and 93% nursing students of grade 2005 approbated this teaching method. Conclusions Introducing computer simulative model of lying-in women into the teaching of gynecological nursing can not only improve the effect of teaching, stimulate studying interest and cultivate unity and cooperation ability.

Objective To explore the biomechanical characteristics of the pharynx in patients with aspiration after radiotherapy for nasopharyngeal carcinoma (NPC).Methods Clinical data on NPC patients with dysphagia admitted between July 2011 and June 2015 were retrospectively analyzed.Twenty-three patients were found who had received videofluoroscopic swallowing studies (VFSSs) and whose pharyngeal pressure and upper esophageal sphincter (UES) relaxing were tested using high-resolution solid-state manometry (HRM).The cases were divided into an aspiration group and a non-aspiration group according to the VFSS results.Differences in biomechanical parameters between the 2 groups when taking food of different viscosity were compared.Results Patients with aspiration had significantly higher UES residual pressure when taking thick liquids (20.1± 14.3 mmHg) and paste (18.0± 14.3 mmHg) than patients not aspirating (9.3±9.2 mmHg and 7.2±8.9 mmHg for thick liquid and paste respectively).But no significant difference in average pharyngeal pressure between the two groups was observed.Conclusion Aspiration after radiotherapy may be correlated with increased UES residual pressure.

Objective To evaluate the differences of clinical features,neuroimaging,angiography and laboratory findings between different stroke subtypes according to TOAST criteria in elderly patients.Methods 91 patients (aged ≥ 80 years) with acute ischemic stroke were retrospectively reviewed in Departement of Neurology from April 2009 to August 2010.Subtypes of ischemic stroke were analyzed according to the classification of TOAST.Risk factors,clinical manifestations,complications,prognosis,neuroimaging,cerebrovascular lesions,and laboratory findings of different TOAST subtypes were compared.Results Large-artery atherosclerosis (LAA) (34/91) was the most common cause of acute ischemic stroke in elderly patients,and most criminal lesions (25/34) located at the intracranial arteries.In the LAA group,patients with intracranial (25/34) or extracranial (12/34) occlusive diseases were more than those in other groups.Patients with cardioembolism (CE) had lower lipid levels.In the CE group,patients with poor shortterm prognosis (7/15) were more than in the LAA or small-artery occlusion (SAO) group,and patients with severe cerebral edema (4/15) were more than those in other groups.In patients of the SAO group,complications occurred infrequently (4/20),and none had poor short-term prognosis.Conclusions There were some differences among different TOAST subtypes in clinical features,neuroimaging,cerebrovascular diseases,and laboratory findings.The clinical significance of our findings needs to be explored further.

Abstract: Malaria is one of the deadliest vector-borne infectious diseases in Africa, seriously endangering human life and health. Among them, cerebral malaria (CM) has a higher morbidity and mortality rate in children, with clinical manifestations primarily involving neurological symptoms, and comprehensive treatment mainly using artemisinin derivatives. When children with cerebral malaria are complicated by congenital heart disease and induce acute hypoxic attacks, the diagnosis and treatment face great difficulties in the absence of effective examination and monitoring treatments. Similar cases have rarely been reported at home and abroad. The paper summarizes and reports a case of a child with cerebral malaria combined with cyanotic congenital heart disease, treated during an aid mission to Africa, who was improved and discharged from the hospital after receiving multidisciplinary anti-malarial, intracranial pressure lowering, neurotrophic and symptomatic supportive treatment. This paper also discusses the diagnosis and treatment process of this child under difficult conditions, combined with current literature reports, in hopes of providing a reference for clinical treatment.

Objective To investigate the clinical and pathologic features of small gastrointestinal stromal tumors (small GISTs,d ＜ 2.0 cm).Methods Medical records of 95 patients undergoing surgery (endoscopic surgery,thoracoscopic/laparoscropic surgery and open surgery)and diagnosed as having GISTs by pathology and immunohistochemistry in Nanfang hospital from October 2003 to June 2014 were retrospectively analyzed.Based on clinical and pathological results,correlation analyses between risk factors for endoscopic ultrasonography(EUS) and Mitotic count(MI),clinicopathologic parameter and NIH risk classification were performed.Results Among 95 cases (104 lesions),88 were single,while 7 were multiple;81.7％ (85/104) small GISTs arose from stomach,including 87.1％ (74/85)in middle-upper stomach;5 cases (5.3％) presented calcification of different degrees,3 cases(3.2％) presented local necrosis and 2 cases (2.1％) with arrangement of epithelioid cells;88 cases (92.6％) were very low grade of NIH risk classification,6 cases (6.3％) were intermediate risk and 1 case(1.1％) was high risk.Positive rates of CD34 and CD117 were 95.8％ (91/95) and 96.8％ (92/95) respectively.The risk factors (border,mucosal surface,echo and heterogeneity) of EUS had no correlation with mitotic count(P＞0.05).The correlation analysis between clinicopathologic features and NIH risk classification revealed tumors more than 1.5 cm had a striking correlation with NIH risk classification (P＜ 0.05).Conclusion Most small GISTs,single or multiple,located at middle-upper stomach,were of very low or low risk,and have a favorable prognosis.But it has worse biological behavior and a higher grade risk when the diameter is more than 1.5 cm,intervention should be recommended.

OBJECTIVE: To observe the protective effect of Huaxia shallot preparation on human umbilical vein endothelial cell (HUVEC) injury induced by oxidized low density lipoprotein (Ox-LDL) in vitro. METHODS: Ox-LDL was prepared and identified, and HUVECs were cultured. After 2-hour intervention of different drugs and 24-hour following intervention of Ox-LDL, the number of HUVECs was observed by phase contrast optical microscope and the activity of the HUVECs was observed by methyl thiazolyl tetrazolium (MTT) technique. Superoxide dismutase (SOD) activity and nitric oxide (NO) content were assayed by respective kit. The protein expressions and mRNA levels of peroxisome proliferators activated receptor gamma(PPAR-gamma) and endothelial nitric oxide synthase (eNOS) were measured by western blot technique and reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Ox-LDL could increase the apoptosis rate of the HUVECs and decrease the NO release as compared with the blank control group (P<0.05). These effects induced by Ox-LDL were all significantly inhibited by Huaxia shallot preparation. It could up-regulate the protein expressions and mRNA levels of PPAR-gamma and eNOS significantly (P<0.05). Huaxia shallot preparation could decrease the apoptosis rate of the HUVECs. CONCLUSION: Ox-LDL may be involved in the initiation and progression of atherosclerosis by injuring the endothelial cells directly and may cause the endothelial dysfunction. Huaxia shallot preparation can protect against Ox-LDL induced endothelial cell injury by up-regulating the protein expressions and mRNA levels of PPAR-gamma and eNOS. It suggests that Huaxia shallot preparation may play a role in the prevention and treatment of cardiovascular disease.
