Objective:To observe the influence of multi-disciplinary cooperation and optimization management mode on the negative situation and rehabilitation effect of patients with affective disorder after coronary heart disease and cerebrovascular disease.Methods:A total of 188 patients with emotional disorders caused by coronary heart disease and cerebrovascular disease from January 2017 to December 2018 to our hospital were selected. According to the random number method, 94 cases in the control group adopted the conventional management model, and 94 cases in the experimental group adopted the multidisciplinary collaborative optimization management model. The negative emotions [evaluated by Self-rating Anxiety Scale (SAS), Self-rating Depression Scale(SDS) ] scores before and after management, the coping style (Jalowies) scores, and quality of life [evaluated by World Health Organization Quality of Life-Brief (WHOQOL-BREF) ] scores were compared between the two groups. The clinical rehabilitation effect and satisfaction rate of related management between the two groups were compared.Results:There were no significant differences between the two groups before management of SAS scores, SDS scores, Jalowies scores, and WHOQOL-BREF quality of life scores ( P> 0.05). After management, the SAS scores and SDS scores of the two groups were significantly reduced, and the Jalowies scores and WHOQOL-BREF quality of life scores were significantly increased. After management, the SAS score and SDS score of the experimental group were 47.32±5.68, 49.93±6.49 and 54.95±6.59, 55.33±8.30 in the control group, the difference was significant between two groups ( t value was 8.503, 4.969, P<0.01). The Jalowies scores and WHOQOL-BREF scores of the experimental group were higher than those of the control group ( t value was -27.662--4.290, P<0.01). The total effective rate of rehabilitation in the experimental group was 98.94%(93/94), which was significantly higher than 90.43%(85/94) in the control group, the difference was statistically significant ( χ2 value was 6.760, P <0.05). The total satisfaction rate of the experimental group for management intervention was 100.00%(94/94), which was significantly higher than the total satisfaction rate of the control group, 91.49%(86/94), the difference was statistically significant ( χ2 value was 6.397, P <0.05). Conclusions:In the patients with affective disorder caused by coronary heart disease and cerebrovascular disease, multi-disciplinary cooperation and optimization management mode can significantly reduce the negative emotions of patients after management, improve the way of patients to deal with the disease, effectively improve the clinical rehabilitation effect and the quality of life of patients, improve the satisfaction rate of patients with management, shorten the distance between nurses and patients, and achieve ideal results.

Objective To observe the efficacy of single Nd-YAG laser treatment for the sub-inner limiting membrane(sub-ILM) haemorrhages in the macular region.Methods This is an uncontrolled case series retrospective study.Nd-YAG laser was performed for 6 patients (6 eyes) with premacular sub-ILM haemorrhages.The best corrected visual acuity(BCVA) and optical coherence tomography(OCT) in macular were observed at 1 day,1 week,1 month and 3 months after operation.The conditation of hematopoietic drainage and complications of macular retina were recorded.Results Sub-ILM haemorrhages were clinically confirmed in 6 patients (aged from 23 to 60 years old),including 4 cases of paroxysm associated with cough,1 case of hypertension,and 1 case of diabetic retinopathy.Funduscopic examination showed sub-inner limiting membrane hemorrhage in the macular region,BCVA count finger (CF) was 0.05 (averagely 0.03).The onset time was from 5 hours to 12 days.All the patients were treated with Nd-YAG laser treatment once,and all of them resulted in excellent partial visual recovery immediately.The average hemorrhage absorption time was 2 weeks.OCT examination showed macular retinal inner limiting membrane calm and foveal shape recovery at 3 month after laser treatment.However,the two patients with hypertension and diabetes recieved vitrectomy at 2 weeks and 1 month after laser surgery respectively because of serious vitreous hemorrhage.Conclusion Single Nd-YAG laser is a safe and effective method in the treatment of simplicity sub-ILM haemorrhages.

Objective To investigate the effects of radiation on the apoptosis rate and expression of 7 apoptosis-related genes in well-differentiated human nasopharyngeal carcinoma cell line CNE-1.Methods CNE-1 cells were cultured in vitro.The apoptosis rates of CNE-1 cells under 0-,2-,4-,6-,and 8-Gy radiation were measured by flow cytometry.The mRNA expression levels of Bcl-2,Bcl-xl,Bcl-w,Bax,Bak,Bad,and Bid were measured by RT-PCR.The Pearson test was used for analyzing the correlation of mRNA expression with apoptosis rate and radiation dose and the correlation between apoptosis rate and survival fraction.Results The early apoptosis rate of CNE-1 cells increased gradually as the radiation dose ranged from 0 to 6 Gy,but decreased when the radiation dose was 8 Gy; the late apoptosis rate of CNE-1 cells increased as the radiation dose ranged from 0 to 8 Gy.The mRNA expression of Bax was upregulated as CNE-1 cells were irradiated,and it was positively correlated with the early/late apoptosis rate and radiation dose (P =0.000 for all comparisons).The mRNA expression of Bcl-xl was downregulated,and it was negatively correlated with the early/late apoptosis rate (P =0.005 and 0.039) ; but it showed no correlation with radiation dose (P =0.369).The mRNA expression of Bcl-2 was upregulated and reached the peak level when the radiation dose was 4 Gy,and then it fell as the radiation dose increased.The mRNA expression of Bcl-w,Bcl-2,Bad,and Bid were not correlated with the early/late apoptosis rate (P =0.058 -0.894).There was no correlation between the apoptosis rate and survival fraction in CNE-1 cells (P =0.064).Conclusions Bax and Bcl-xl have some correlation with apoptosis rate in CNE-1 cells,but no correlation between the apoptosis rate and survival fraction was observed.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.

Objective To investigate the differential MSCT diagnostic features and comparative study of subtypes of renal cell carcinoma (RCC). Methods All of the renal cell carcinomas including 14 chromophobe RCCs (ChRCC), 10 papillary RCCs type 1(PRCC Ⅰ), 15 papillary RCCs type 2 (PRCC Ⅱ), 7 mucinous tubular and spindle cell carcinomas (MTSCCs) were investigated except for clear cell RCC. Dynamic contrast-enhanced CT was conducted in each case after intravenous administration of contrast agent, and the data including all the CT manifestations and the enhancement features were analyzed and contrasted together. Results The indexes including enhancement homogeneity, border of the tumor, renal pelvis violation, blood vessel in tumor showed statistically significant difference between the 4 subtypes (P<0.05), but no difference in the calcification of the tumor. Only the enhancement degree of MTSCC was lower than the kidney medulla in all of the three enhancement scanning phases, while the other 3 tumors' enhancement degree was higher than the kidney medulla in the cortical phase. Peak contrast enhancement of ChRCC was located in the cortical phase, however, peak contrast enhancement of the others did in the nephrographic phase. Conclusions Enhancement characteristics combined CT features is of great help in differential diagnosis of 4 subtypes of RCC.
