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.

The authors reviewed the practice of integrated health care delivery system( IDS) at home and abroad, and based on experiences of collaborations between medical service institutions in Zhejiang province,proposed the strategic positioning,responsibilities and service innovation of urban public hospitals in a regional medical service system. It is held that the direction of China′s health care reform should move towards IDS in the future,and such hospitals should play an active role in the process via integration of its own resource and provide multi-level,diversified services for the regional health care system.

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 explore the application value of deep learning image reconstruction(DLIR)algorithm in low-dose deep inferior epigastric artery(DIEA)computed tomography angiography(CTA).Methods A total of 59 patients undergoing DIEA CTA were prospectively selected and randomly divided into two groups:group A(29 cases)and group B(30 cases).Group A was the conventional radiation dose group(tube voltage 120 kVp),the tube current was dose modulation 3,and the iterative reconstruction algo-rithm was Karl 5.Group B was the low radiation dose group(tube voltage 120 kVp),the tube current was dose modulation 2,with DLIR reconstruction algorithm,and four levels of DLIR(1-4)were reconstructed and labeled as groups B1 to B4.The mean tube current,vol-ume CT dose index(CTDIvol),and dose length product(DLP)of group A and group B were recorded,and the effective dose(ED)was calculated.The CT and standard deviation(SD)values of the external iliac artery and psoas major muscle were measured on axial images of each group,and signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.Two observers using double-blind method independently evaluated the DIEA on volume rendering(VR)and maximum intensity projection(MIP)images of each group using a 3-point scale,and a 5-point scale was used to evaluate the overall image quality on axial images.Results Compared with group A,the mean tube current and ED in group B were decreased by 39.33％and 44.09％,respectively(P＜0.05).With the increasing of DLIR level from groups B1 to B4,the SD value of the image gradually decreased,while SNR and CNR gradually increased(P＜0.05).The CNR in groups B3 and B4 was higher than that in group A(P＜0.05).The subjective scores of the two observers were consistent(Kappa value 0.779-0.889,P＜0.05),and there was no statistical significance between group A and group B in the perforating vessels from the DIEA,intramuscular course,and the point of emergence(P＞0.05).With the increase in DLIR level,the subjective score of the overall image quality from group B1 to group B4 showed a trend of first increasing and then decreasing,and the score of group B3 was the highest(4.50±0.51)points,which had no statistical significance compared with group A(4.45±0.51)points(P＞0.05).Conclusion DLIR can effectively reduce the radiation dose of the DIEA CT A scan and ensure the image quality,among which DLIR 3 is the recommended best reconstruction grade.

Objective To explore the application value of 1 024×1 024 reconstruction matrix combined with iterative reconstruc-tion algorithm(Karl)in deep inferior epigastric artery(DIEA)computed tomography angiography(CTA).Methods A total of 40 patients who underwent DIEA CTA were prospectively selected and the original data were reconstructed by grouping.Group A was reconstructed using a conventional 512×512 matrix combined with Karl 5 grade.Group B was reconstructed using 1 024×1 024 recon-struction matrix combined with Karl 5,7,and 9 grades,respectively,and 3 subgroups B1-B3 were obtained.The CT and standard devia-tion(SD)values of the external iliac artery and psoas major muscle were measured on axial images,and signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.A 3-point scale was used to evaluate the perforating vessels from the DIEA,intramuscular course,point of emergence,superficial inferior epigastric artery(SIEA)and superficial inferior epigastric vein(SIEV)on volume ren-dering(VR)and maximum intensity projection(MIP)images by two observers,and a 5-point scale was used to evaluate the overall image quality on axial images.Results With the increase of Karl grade in groups B1 to B3,the SD value of the external iliac artery decreased gradually(P＜0.05),while SNR and CNR increased gradually(P＜0.05).The SD values of the external iliac artery in group B2 and group B3 were lower than those in group A(P＜0.05),and SNR and CNR were higher than those in group A(P＜0.05).There was a good consistency in the subjective evaluation between the two observers(Kappa values=0.773-0.872,P＜0.05).The perforating vessels from the DIEA,intramuscular course,point of emergence,SIEA and SIEV display and overall image quality subjective scores of group B2 and group B3 were better than those of group A(P＜0.05),and the scores of group B2 showed the greatest improvement.Conclusion The 1 024 × 1 024 reconstruction matrix combined with the Karl 7 reconstruction algorithm can optimize the image quality and improve the display of the DIEA and perforator microvessels.
