Objective To study the psychological changes and the effect of psychological intervention and to discuss the influence of psychological rehabilitation on carcinoma patients after comprehensive interventional therapy.Methods 100 carcinoma patients were divided into two groups randomly:the psychological intervention group(50 casea) received both psychological intervention therapy and comprehensive intervention therapy;the control group (50 cases) received only comprehensive interventional therapy;Curative effects were assessed with the Symptom Checklist90(SCL-90) ,the Self Rating Depression Scale(SDS) and the Self Rating Anxiety Scale(SAS) for each patient. Results For the psychological intervention group, SCL-90 scores after therapy was significantly lower than that before therapy ( P < 0. 05 ), and were also significantly lower than that ( without anxiety agent) of the control group. The scores of SDS and SAS in post-therapy patients were significantly lower than that of pre-therapy patients in the psychological intervention group. The scores of SDS had no statistical difference between post-therapy patients and pre-therapy patients in the control group. The scores of SAS in post-therapy patients was significantly lower than that of pre-therapy patients in the control group. Both scores of SDS and SAS in the control group were significantly higher than that of the psychological intervention group after therapy. Conclusion Psychological intervention for carcinoma patients after comprehensive interventional therapy played an promotional role in psychological rehabilitation in the community.

Objective Analyze the amino acids and acylcarnitines in the blood of patients first diagnosed with uremia using tandem mass spectrometry in order to provide a basis for clinical diagnosis and treatment. Methods 30 patients with uremia were selected as the research objects,while 15 cases of healthy person were served as the control. The values of 11 kinds of amino acids and 2 kinds of acylcarnitines in the two groups were detected using tandem mass spectrometry,and the data were analyzed and compared. Results The levels of alanine(Ala)and tyrosine(Tyr)in uremia group were significantly lower than those in control group(P < 0.05),while the levels of citrulline(Cit),glycine(Gly)and proline(Pro)were significantly higher in uremia group than in control group (P < 0.05). The differences were mainly in non-essential amino acids between the two groups. The levels of free carnitines and total carnitines in uremia group were significantly higher than those in normal group(P < 0.05). Conclusion For the patients first diagnosed with uremia(not treated with replacement therapy),the disturbance of amino acid metabolism mainly in non-essential amino acids were found in their blood,and the carnitine levels were higher than normal levels. The results could provide the basis for clinical nutrition therapy for patients with uremia.

Objective To explore the in vitro spermostatic effects and the mechanisms of ceritinib,a novel candidate from the active compound pools previously screened for the regulation of sperm function.Methods The vigor sperm of human and mouse were incubated with ceritinib for 20seconds,and the sperm motility was evaluated by computer assistant sperm analysis (CASA).The integrity of the sperm plasma membrane and the survival ratio of sperm was assessed by hypo-osmotic swelling (HOS) assay and SYBR-14/PI staining.The damage of sperm plasma membrane was detected by electron microscope.The cytotoxicity of ceritinib to VK2/E6E7,End1/E6E7 and Ect1/E6E7 cells was measured by CCK-8 assay and fluorescent staining.Results The minimal effective concentration (MEC) of ceritinib to (5-10) × 106/mL human sperm within 20 seconds was (74.87 ± 31.46)μmol/L,which was significantly lower than the MEC of nonoxynol-9 (219.75 ± 20.89) μmol/L measured in the same condition.The time-dose related spermostatic effects of ceritinib were measured by CASA system.Ceritinib was able to damage sperm membrane and caused sperm death with HOS and SYBR-14/PI staining.With electron microscopy,the sperm membrane was observed to be ruptured,and the heads and tails of sperm were separated by ceritinib.Ceritinib was also able to damage the epithelial cells.Conclusions Ceritinib has acute spermostatic effects and potential contraceptive effects.

Objective To identify the risk factors associated with cardiovascular and cerebrovascular disease (CCVD) in maintenance hemodialysis (MHD) patients. Methods We analyzed all of the patients undergoing maintenance hemodialysis in the dialysis center of the 3rd Affiliated Hospital of Sun Yat-sen University for at least 3 months from Jan 1st, 2009 to Dec 31st, 2014. Baseline and yearly interval clinical data were recorded and patients were followed up until morbidity or death of CCVD. Cox proportional hazard regression and time-dependent Cox regression were used to estimate the relative risk of outcomes associated with clinical measurements. Results There were 243 patients enrolled in the study, with a mean age of (53.2 ± 16.4) years old, and 138 of them were male (56.8%). The multivariate Cox proportional model revealed that age (HR=1.040, 95%CI:1.015-1.065, P=0.002), Erythropoietin (EPO) dose (HR=0.914, 95%CI: 0.846-0.987, P=0.022) and history of cardiovascular and cerebrovascular disease (HR=4.045, 95%CI: 2.074-7.890, P<0.001) were independent predictors of CCVD in MHD patients. After adjusting for baseline predictors, time-dependent serum phosphorus level (HR=1.722, 95%CI: 1.034-2.866, P=0.037) was significantly associated with CCVD. Conclusion Older age, decreases in EPO dose and history of cardiovascular and cerebrovascular disease were associated with increased risks of CCVD in MHD patients. Increase in serum phosphorus level was associated with increased risks of CCVD in a time-dependent manner.

Objective To evaluate the diagnostic value of gray-scale ultrasonography (GSU) combined with contrast-enhanced ultrasonography (CEUS) and real-time elastography imaging (EI) in solid thyroid nodules.Methods A total of 124 solid nodules were collected from Xuanwu Hospital of Capital Medical University from September 2011 to November 2014, including 49 benign nodules and 75 malignant nodules conifrmed by surgical pathology. The data of multimodal imaging were retrospectively analyzed and compared with the pathological results. The parameters among the groups were compared byχ2 test. Four diagnostic models including the statistically signiifcant independent variables were established accord to different combinations of routine ultrasound examination. The binary Logistic regression equation using the pathological results as the dependent variable Y and the ultrasound features of thyroid nodules as independent variableX was established for calculating the area under the receiver operator curve (ROC) and multiple regression analysis furthermore.Results There were statistically significant differences in aspect ratio, margin condition, echo type, CEUS features, elastic imaging score and elastic strain rate of benign and malignant thyroid nodules(χ2=13.966, 7.106, 24.215, 17.250 and 27.158,P<0.05).The four Logistic regression models were statistically signiifcant (χ2=5.37, 5.37, 8.155, 8.155, allP<0.05). By using modelⅠ,Ⅱ,Ⅲ andⅣ, the diagnostic sensitivity, speciifcity and accuracy of malignant nodules were (73.8%, 75.9%, 79.7%, 83.3%), (67.5%, 70.7%, 85.2%, 86.7%), and (71.8%, 74.2% 81.8%, 84.4%) respectively. The area under the ROC of logistic equation predicted values were (0.778, 0.809, 0.875 and 0.898, allP<0.01). Multivariate categorical analysis showed that aspect ratio, margin condition and the elastic strain rate ratio (χ2=13.73, 7.541 and 11.461, allP<0.05) of thyroid nodules were effective diagnostic indicators. Conclusions Our study indicated that CEUS and EI could be helpful modality for GSU to improve the diagnostic accuracy of thyroid nodules. The combined application of multi mode ultrasound examination has a high diagnostic value.

Objective To assess the diagnostic value of contrast enhanced ultrasound (CEUS),elastography and their combined use in diagnosing thyroid nodules of thyroid imaging reporting and data system (TI-RADS) 4. Methods From November 2011 to August 2016, 159 TI-RADS 4 nodules diagnosed by conventional ultrasound were prospectively enrolled and examined by CEUS and elastography before surgery. Multivariate logistic regression models were established for CEUS and CEUS combined with elastography to diagnose thyroid malignancy. The diagnostic performances of CEUS, elastography and their combined use were evaluated with the receiver operating characteristic (ROC) curve. The sensitivity,specificity, accuracy, positive predictive value, negative predictive value and omission diagnostic rate of CEUS, elastography and their combined use were compared by Chi-square test. Results The CEUS features significantly predicting malignancy were heterogeneous enhancement, hypoenhancement, without or incomplete ring-enhancement and later time to peak than the surrounding parenchyma (χ2=24.378, 69.194,29.434 and 7.375, all P < 0.01). Furthermore, the multivariate logistic regression for CEUS combined with elastography showed that heterogeneous enhancement, ring enhancement and elasticity score were the independent predictors of thyroid malignancy. The area under the ROC curve of CEUS combined with elastography was (0.921±0.023) which was higher than that of CEUS and elatography (0.88±0.029 and 0.80±0.038, respectively; both P < 0.05). Moreover, the sensitivity, accuracy and negative predictive value of CEUS combined with elastography were 92.1%, 86.2% and 84.6%, respectively. The omission diagnostic rate of CEUS combined with elastography (7.9%) was reduced. And the diagnostic accuracy of CEUS combined with elastography was significantly higher than that of CEUS and elastography (P < 0.05). While the diagnostic accuracy of CEUS was close to the elastography, the difference was not statistically significant (P > 0.05). Conclusion The diagnostic value of CEUS combined with elastography was remarkably significant in the differential diagnosis of TI-RADS 4 nodules.
