Objective:To investigate the mechanism of survivin, p53 and Ki-67 on Hep-2 human laryngeal cancer endothelial cell proliferation and invasion.Methods:Laryngeal squamous cell carcinoma and paracancerous normal tissues were collected, total RNA was extracted from tissues,survivin,p53and Ki-67gene mRNA expression levels in laryngeal cancer and the adjacent tissues were detected by Real-time PCR. Human laryngeal cancer Hep-2 epithelial cells were selected,survivin gene was overexpressed, and cell proliferation was detected by MTT.p53 andKi-67gene expression changes in overexpressedsurvivin gene were detected by Western blot. Changes in Hep-2 cell invasive ability were studied whensurvivin was overexpressed as detected by Transwell invasion assay.Results: In the adjacent tissues, survivin,p53andKi-67 gene relative expression levels were 1.72 ± 0.9, 13.7 ± 5.7 and 5.7 ± 1.3, respectively; while in cancer tissues, gene relative expression levels were 53.7 ± 8.3, 66.7 ± 5.2 and 61.0 ± 3.1, respectively, which was significantly increased. As detected by MTT, relative cell survival rate within 12 h ofsurvivinoverexpression were: load control group, (88.5±1.6)%; overexpressed group, (90.3±1.9)%. Transwell invasion assay results indicated that overexpressedsurvivincould significantly increase the relative survival rate of cells. Conclusions:Expressions ofp53,Ki67 and survivin are increased in cancer; and there is a positive correlation betweensurvivin, p53andKi67 expressions in laryngeal carcinoma.

OBJECTIVE: To investigate the expression of Survivin, p53 and Ki67 in laryngeal carcinoma and the relation with clinical data. METHOD: Immunohistochemical staining (SP) was used to detect expression of Survivin, p53 and Ki67 of 64 cases with laryngeal carcinoma, 26 cases with precancerosis, 34 cases with vocal polyps. RESULT: The positive expression rates of Survivin, p53 and Ki67 were 59.4%, 68.8%, 65.6% respectively in laryngeal carcinoma, which were significantly higher than those in precancerosis and vocal polyps (P < 0.01). The expression of Survivin, p53 and Ki67 in laryngeal carcinoma were significantly statistical different in TNM stage and lymph node metastasis (P < 0.05), but were not correlated with patients' ages, the pathological grades, 3 years and 5 years surviving rates (P > 0.05). The expression of Survivin, Ki-67 and p53 was positively correlated (r = 0.607, 0.541, 0.648, P < 0.01) in laryngeal carcinoma. CONCLUSION Survivin, p53 and Ki-67 may play an important role in the carcinogenesis and progress of laryngeal carcinoma. They may play synergetic roles in the process of carcinogenesis of laryngeal carcinoma.

Objective To investigate the effect of intraurethral irrigation with honeysuckle water-decoction on formation of bacterial biofilm on the surface of the catheter. Methods Eighty male patients,who had no history of catheterization and no urinary infection with negative results of urine bacterial culture,were enrolled in the study. All patients were randomly divided into 4 groups with 20 cases in each: group A (patients underwent intraurethral irrigation with honeysuckle water-decoction); group B (intraurethral irrigation with 25% PVP); group C (intraurethral irrigation with normal saline ) and group D (no intraurethral irrigation). The urethral catheters were removed at the 7th day and the bacterial biofilm on the surface of the catheter was examined by scanning electron microscopy (SEM). Results SEM demonstrated uneven- distributed matrixes coated on the surface of the catheter, and bacteria adhered to the matrixes. The average thickness of biofilm in group A, B, C and D was (17.876 ±11.788)μn, (31.090±15. 006)μm,(33.716±11.927)μm, (67.762±23.588)μm, respectively. The average thickness of biofilm in group A, B, C was significantly thinner than that in group D (P<0.01), and the thickness in group A was thinner than that in group B and C (P<0.01), but there was no significance difference between group B and group C (P>0.01). Conclusions Intraurethral irrigation with honeysuckle water-decoction can effectively reduce the formation of bacterial biofilm on the surface of the catheter.

Objective:To understand the status of life quality, resilience and disability acceptance of burn patients, and to explore the impact of mental resilience and disability acceptance on the quality of life.Methods:Connor-Davidson Resilience Scale (CD-RISC), Acceptance of Disability Scale (ADS) and Burn Specific Health Scale-Brief (BSHS-B) were used to carry out questionnaire survey for a total of 315 burned patients who were in rehabilitation phase.Results:For burned patients, the total score of resilience was 57.12±14.34, the total score of disability acceptance was 78.20 ±9.99, and the total score of quality of life was 128.29 ±37.26. The correlation analysis showed that the total score of resilience was positively correlated with quality of life for burned patients ( r value was 0.646, P<0.01); the total score of disability acceptance was positively correlated with the total score of quality of life for burned patients ( r value was 0.846, P < 0.01). Multiple stepwise regression showed that the total score of disability acceptance, severity of burn, sleep state, ability and endurance of negative emotions were the main predictors of the quality of life for burned patients. Conclusions:Great attention should be paid to the quality of life of burned patients, and psychological problems of high-risk patients should be found as soon as possible and reasonable intervention should be given to improve the resilience and disability acceptance of patients, so as to improve their quality of life.

Objective:To investigate the effect of the combination of Auto-prescription and ODM full on image quality and radiation dose of chest enhanced CT inorder to explore the feasibility of individualized low radiation dose chest enhanced CT. Methods:The phantoms PH-75 in two sizes were scanned with four scanning modes: group A, 120 kVp + Smart-mA; group B, 120 kVp + Smart-mA+ ODM full; group C, Auto-prescription + Smart-mA; group D, Auto-prescription + Smart-mA+ ODM full. The images of each group were reconstructed with 40%-80% ASIR-V (interval 20%), recorded as A 1-3-D 1-3. Image quality and radiation dose were evaluated in order to obtain optimal scanning modes. Totally 35 cases(from the First Hospital of Dalian Medical University during November 2021 to July 2022) of chest enhancement CT were collected prospectively in the clinical study using the parameters of D 2 group recorded as D patients. Patients in this group received chest enhancement CT scanning for the second time within three months. The CT parameters in first enhanced scanning recorded as A patient were as same as those in group A 1, and the parameters in second scanning recorded as D patient were as same as those in group D 2. The SNRs, CNRs, subjective grading and imaging findings of the lesion in two groups were compared. Results:In phantom study, the radiation dose of each group was statistically significant, and that in D group was the lowest. For two sizes of phantoms, A 1 was uesd as the control group in pairwise comparison. The SDs of B 1, C 1, and D 2 images had no statistical difference with that of A 1 ( P > 0.05), and SD of D 1was higher than that of A 1, and SDs of other groups were lower than that of A 1( F=10.77, 122.50, P<0.05). CNR of B 1 had no statistical difference with that of A 1, and the CNRs of other groups were higher( F=136.20, 30.21, P<0.05). Subjective scores of A 2, C 2, D 2 had no statistical difference with that of A 1 and those of other groups were lower than that of A 1( H=52.89, 43.95, P<0.05). In clinical study, 80 kVp was uesd for 22 cases and 100 kVp was used for 13 cases in D patients group. SNRs and CNRs in the D patients group were all higher than those in the A patients group ( P > 0.05). The consistency of image quality scores for two observers was good ( kappa = 0.754, P < 0.05). The median scores of the two groups were (4, 4). Conclusion:Auto-prescription combined with ODM full in chest enhanced CT imaging can achieve individualized low radiation dose with meeting the requirements of image quality and clinical diagnosis.
