Objective To analyze tissue vascular endothelial growth factor receptor 1 (VEGFR-1)and VEGFR-2 and their soluble form (sVEFGR-1 and sVEGFR-2) in the plasma in patients with preeclampsia,and to explore its clinical significance.Methods sVEGFR-1 and sVEGFR-2 expressions in plasma of normal pregnancy women and preeclampsia patients were detected by enzyme-linked immunosorbnent assay (ELISA) ; VEGFR-1,VEGFR-2,sVEGFR-1 and sVEGFR-2 mRNA expressions of normal pregnancy women and preeclampsia patients in placenta were detected by reverse transcription-polymerase chain reaction (RT-PCR).Results ELISA results showed that the level of sVEGFR-1 in plasma of normal control group before and after delivery was (12.33 ± 1.52) ng/ml and (4.55 ± 0.31) ng/ml,respectively,while that of preeclampsia group was (77.25 ± 9.47) ng/ml and (8.13 ± 0.74) ng/ml,respectively; the differences between before and after delivery in the two groups were of statistical significance.The level of sVEGFR 2 in plasma of normal control group before and after delivery was (8.74 ± 1.24) ng/ml and (6.43± 0.55) ng/ml,respectively,while that of preeclampsia group was (5.69 ± 0.75) ng/ml and (4.96 ±0.67) ng/ml,respectively.RT-PCR results were consistent with ELISA results.Conclusions Rapid decrease of plasma sVEGFR-1 and continuously low-level expression of plasma sVEGFR-2 indicated that VEGFR-1 might be closely related to preeclampsia,and decrease of plasma sVEGFR-2 in preeclampsia women might be taken as a marker of endothelial cell function disorder.

Objective To investigate and analyze the personality characteristics and situation of mental health in patients with sudden deafness,and discuss the relationship between the two,so as to provide basis for the auxiliary diagnosis and mental health intervention.Methods Eighty-eight patients with sudden deafness(sudden deafness group) were evaluated by Symptom Checklist 90 (SCL-90) and adult Eysenck Personality Questionnaire (EPQ).The survey results were compared with the norm of healthy people (norm group).The correlation analysis was performed between SCL-90 results and EPQ score.Results The SCL-90 total score in sudden deafness group was higher than that in normal group,but there was no significant difference,P>0.05.The scores of somatization,depression,anxiety,panic,psychosis and positive number,positive projects split were (1.58±0.46),(1.71±0.43),(1.59±0.44),(1.38±0.39),(1.46±0.51) scores,(32.65±15.81) nubmers,(2.96±0.65) scores in sudden deafness group,which were higher than those in normal group (1.37±0.48),(1.50±0.59),(1.39±0.43),(1.23±0.41),(1.29±0.42) scores,(24.92±18.14) nubmers,(2.60±0.59) scores,and there were significant differences,t=3.640,2.996,3.855,3.045,3.314,3.562,5.033,P＜0.01.The standard T points of psychotic,neurotic and emotional stability dimensions were (54.63±10.37),(45.59±8.67) scores in sudden deafness group,which were higher than those in normal group (48.14±9.74),(41.27±9.42) scores,and there were significant differences,t=8.207,3.811,P＜0.01.The standard T points of internal and external dimensions,hide were (52.28±11.67),(48.68±8.57) scores in sudden deafness group,which were lower than those in normal group (57.75±8.26),(51.27±10.43) scores,and there were significant differences,t=5.455,2.066,P＜0.01 or 0.05.Neurotic and emotional stability dimension,psychotic part dimension were a positive correlation with SCL-90 factor points.Multi-factor stepwise regression analysis showed that the neurotic or emotional stability were correlated with interpersonal relationship,depression,anxiety,hostility,terror.Conclusions Patients with sudden deafness overall mental health status is poorer,the somatization,depression,anxiety,terror,psychoticism of various factors on negative emotions is more obvious.Sudden deafness patients have emotional instability and psychotic personality characteristics.The personality characteristics of sudden deafness patients have a correlation with the mental health.In the process of comprehensive treatment for patients with sudden hearing loss,individual psychological health intervention is necessary.

Objective To investigate the telephone information-memory-concentration test (TIMCT) in evaluating the cognitive function of patients with nasopharyngeal carcinoma(NPC)after radiotherapy. Methods The cognitive function were evaluated by TIMCT and mini mental state examination (MMSE) in 2 weeks for 30 normal persons and 90 NPC patients. And the 90 NPC patients were divided into the 3 months, 2 years and 5 years after radiotherapy groups. All patients were carried out firstly face to face interview and telephone interview 1 time after 2 weeks. Results The correlation coefficient of all groups between TIMCT(telephone) and TIMCT (face to face) were bigger (R = 0.850) when MMSE wasn't control variable. And the correlation coefficients between TIMCT (telephone) and TIMCT (face to face) were lower (R = 0.366) when MMSE was control variable. As for examining time was classification factor, TIMCT (telephone) and TIMCT (face to face) were analyzed by partial correlation analysis. Only normal group was correlated with group of 3 months after radiotherapy and group of 2 years after radiotherapy wasn't correlated with group of 5 years after radiotherapy (R = 0.447,0.970,0.200 and 0.062). In addition, the difference plot of TIMCT(telephone) and TIMCT (face to face) indicated that telephone was consistent with face to face interview (MMSE≥28). Both telephone and face to face interview reflected the cognitive function downtrend of rescareh objects. Conclusions TIMCT (telephone), TIMCT(face to face) and MMSE (face to face) can reflect cognitive function downterend of patients with NPC after radiotherapy. But TIMCT(telephone) used in clinical screening cognitive function impairment of patients with NPC after radiotherapy should be improved further.

Objective:To investiate biological properties of Mesenchymal stem cell(BMSC) from rat bone marrow in vitro,and their effects in inducing immune tolerance.Methods:BMSCs were obtained from rat bone marrow by density gradient centrifugation and selected by cell attachment.The morphology of BMSCs was observed by electron microscope.The expression of surface molecules of CD34 and CD44 was analyzed by flow cytometry.The cells were injected ex vivo intravenously after in vitro culture and then CD4+ CD25+ Treg ratio were determined.The proliferation of thymic cells was estimated by 3H-TdR incorporation method.Results:BMSCs were fibroblast-like cells.The expression ratio of CD44 in BMSCs was 98%,but expression of CD34 was negative.After administration of BMSCs,the ratio of CD4+CD25+Treg(2.5%?0.69%) from peripheral blood of rats was higher than in normal group(0.8%?0.14%) and PBS control group(1.0%?0.23%),P

Objective:To investigate efficacy before and after operation of Information-motivation-behavior nursing model in low-temperature plasma tonsillectomy.Methods:A total of 132 cases of tonsillectomy patients admitted to our department of otolaryngology from January 2016 to January 2017 were selected as research objects. All patients were divided into observation group and control group by random number table method, with 66 cases in each group. Cold plasma tonsillectomy was performed in both groups. The control group received routine nursing measures, and the observation group received IMB nursing mode based on the information - motivation - behavioral skills model. The psychological and emotional scores, surgical awareness, behavior and quality of life scores of patients in the two groups were compared.Results:There was no significant difference in Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores of patients in the observation and control groups before nursing, and SAS and SDS scores of patients in the observation group [SAS (40.56±2.12); SDS (40.56±2.12)] and control group [SAS (50.24±2.14); SDS (47.66±2.57)] were significantly decreased after 1 month of nursing ( t value was13.958, P=0.000), and there were statistically significant differences in the scores between two groups ( t value was 26.106, P=0.000). Before nursing, there was no statistically significant difference in surgical awareness between the two groups, and there was a significant difference in surgical awareness between the observation group (96.97%, 64/66) and control group (84.85%, 56/66) 1 month after nursing ( χ2 value was 16.810, P=0.000), and the observation group was higher than the control group. The scores of the observation group on regular work and rest, taking medicine on time, giving up smoking and drinking, healthy diet, and rehabilitation training (96.12±2.33, 95.72±2.16, 96.96±2.56, 95.68±2.14, 96.45±2.69) were higher than those of the control group (88.42±5.12, 89.86±5.33, 90.13±5.22, 87.61±5.36, 88.19±5.43). There was significant difference in those scores ( t value was 8.278-11.360, P=0.000). After 1 month of nursing, SF-36 scores of patients in the observation group (86.47±6.99) were significantly higher than those in the control group (74.28±7.23) and the difference was statistically significant ( t value was 9.848, P=0.000). Conclusions:Information - motivation - behavior nursing model is helpful to improve the psychological state of patients before and after low-temperature plasma tonsillectomy, and improve the patients′ awareness of the operation and quality of life.
