ObjectiveTo explore the effect of cognitive therapy and progressive relaxation training (CTPRT) on the operation anxiety of patients undergoing chemonucleolysis with collagenase.Methods120 patients undergoing chemonucleolysis with collagenase were randomly assigned to the experimental group and the control group.The experimental group received routine care and CTPRT,while the control group only received routine care.The perioperative anxiety status,back and leg pain,heart rate,blood pressure,status of sleeping and urination of the two groups were evaluated respectively.ResultsAnxiety and pain degree in the experimental group was significantly lower than that of the control group (P<0.01).About 30 min pre operation and postoperation,the heart rate and blood pressure of the experimental group were much lower than that of the control group (P<0.01).The experimental group also showed better sleep and urination status.ConclusionsThe cognitive therapy and progressive relaxation training can reduce degree of operation anxiety,release the pain and help promote sleep for patients undergoing chemonucleolysis with collagenase.

Objective To investigate the technical points and the clinical effectiveness of transcatheter arterial chemoembolization (TACE) combined with CT-guided ~(125)I radioactive particle implantation for the treatment of liver cancer. Methods Twenty-seven patients with hepatic cancer, proved by color Doppler ultrasonography, CT and AFP, were enrolled in this study. All the patients received embolization therapy with lipiodol not long before. Of the 27 patients, preoperative CT scanning was performed in 16. Based on the CT findings, the therapeutic protocol was formulated to determine the amount and site of ~(125)I radioactive particle to be implanted. When drawing the outline of target area, the targeted sedimentation extent which was delineated on CT scan should be exceeded the area with deposits of lipiodol by 0.5-1.0 cm. The average energy of ~(125)I radioactive particle was 27-35 keV. Results Of 27 patients, complete remission was seen in 2, partial remission in 16, unchanged condition in 6 and exacerbation of the condition in 3, with a total efficiency of 66.7%. The patients were followed up for 6 months. One patient died of distant metastasis and the remaining ones survived so far. Conclusion Transcatheter arterial chemoembolization combined with CT-guided ~(125)I radioactive particle implantation is a safe and effective treatment for liver cancer.

Objective This paper is to explore the relationship between the placement of the bone oscillator and bone-conducted thresholds to ASSR stimuli in adults with normal hearing and to investigate the amplitude and the threshold differences to bone-conducted auditory steady-state responses (BC-ASSR) stimuli between single - and multiple-stimulus conditions. Methods Two groups of subjects were selected with 0. 5, 1, 2 and 4 kHz brief tones repeated at the rate of 77, 87, 93 and 101 Hz using a B-71 bone oscillator either in single- or multiple ted no significant differences between mastoid and behind-the-ear placements. The mean and standard deviations of bone-conducted behavioral thresholds to ASSR stimuli at 0.5, 1, 2 and 4 kHz were 62.6±4.8,47.1±4.8,46.8cant difference between the two conditions while the mean and standard deviations of BC-ASSR thresholds at 0.5, 1, 2 and 4 kHz were 96.7±9.7,70.3±11.6,60.6±7.4,52.8±7.2 dB re: 1μN (ppe), respectively. Conclusion The behavioral bone-conducted thresholds to ASSR stimuli with mastoid and behind-the-ear placemen yielded no significant differences. When the stimuli intensity was 50 dB nHL, the amplitudes in single-stimulus condition were significantly higher than those to multiple-stimulus condition. There were no significant differences for BC-ASSR thresholds between single- and multiple-stimulus condition.

Primary intraocular lymphoma (PIOL) is mostly composed by diffuse large B-cell lymphoma with a high degree of malignancy and often masquerades as uveitis.Moreover,it has a poor prognosis,therefore the early diagnosis and treatment are very important.Cytology,cytokine analysis,immunohistochemistry and genetic testing are often used in combination to improve the diagnosis rate of PIOL,however,eye tissue biopsy is the gold standard for diagnosis of PIOL.Currently,since there is no unified treatment program,the main treatment is given priority to local chemotherapy and orbital radiotherapy,and the use of multiple therapies can improve the efficacy of refractory PIOL.Base on these,this article reviews the current diagnosis and treatment for providing certain reference.

OBJECTIVETo investigate the action mechanisms of the FZD5 gene in prostate cancer bone metastasis and search for some new treatments for this disease.

METHODSWe determined the expression level of the FZD5 gene in prostate cancer PC3 cells and, after transfection of siRNA into the PC3 cells and silence of the FZD5 gene, observed the changes in the migration and proliferation of the cells. We established the model of prostate cancer bone metastasis by tibial injection of prostate cancer cells in the nude mice. Then we injected control siRNA and FZD5-silenced siRNA into the tibia of the mice followed by evaluation of tumor-induced bone destruction by X-ray imaging at 0, 1, and 3 weeks and by HE staining at 3 weeks after injection.

RESULTSAfter transfection of FZD5-silenced siRNA into the prostate cancer PC3 cells, the expression of the FZD5 gene was decreased about 70%. The rate of cell proliferation was significantly lower in the gene silencing group than in the control (P < 0.05), and that of cell migration dropped by 30% in the former as compared with the latter group at 48 hours after FZD5 silencing (P < 0.05). At 3 weeks after injection of control siRNA or FZD5-silenced siRNA into the tibia of the mice, osteolytic damage was observed in both groups, though less in the FZD5 silencing group, with only a few remaining bone trabeculae visible.

CONCLUSIONSilencing the FZD5 gene can reduce the migration and proliferation of prostate cancer cells, help to suppress bone metastasis and destruction, and thereby improve the survival rate and quality of life of the patients.

Objective To compare the efficacy of carotid endarterectomy(CEA)and carotid artery stenting(CAS)for the treatment of high-risk atherosclerotic carotid artery stenosis.Methods We retrospectively studied the surgical outcomes of 58 patients with high-risk atherosclerotic carotid artery stenosis.Among the cases,32 received CEA and 26 underwent CAS.All of the patients were followed up with carotid ultrasonography,CTA or DSA in 30 days,6 months,and 1 year after the procedures,their neurological function was assessed meanwhile.Cumulative incidence of death,stroke,or myocardial infarction within 30 days after the surgical intervention and death or ipsilateral stroke events between 30 days and 1 year were set as the primary endpoint of the study.And the secondary endpoints were the CEA or CAS-correlated complications or severe restenosis within 1 year after the treatment.The outcomes of the two groups were compared.Results The primary endpoint occurred in 3 patients in the CEA group(9.4%)and 4 in the CAS group(15.4%)(?2=0.086,P= 0.769).And the secondary endpoint was found in 4 of the CEA group(12.5%)and 4 of the CAS group(15.4%)respectively(?2=0.000,P=1.000).Conclusions For the patients with high-risk carotid artery stenosis and coexisting conditions,CEA is as safe and effective as CAS.

ObjectiveTo provide a reference for the establishment and appliance of enzyme reference measurement of CK in China by comparing and analyzing the RELA results of CK in IFCC from 2006-2008. Methods The RELA samples of CK were measured according to the reference procedure for the measurement of catalytic activity concentration of CK (37 ℃) ,which had been published by IFCC. The EP5A2 protocol was used for evaluation of the imprecision and ERM was used for verification of the trueness. Results In RELA 2006, the result of sample A was (9. 896 ±0. 112) μkat/L, and the result of sample B was (4.953 ±0. 120) μkat/L. In RELA 2007, the result of sample A was (2.684 ±0.054)μkat/L, and the result of sample B was (8.798 μ0. 101) μkat/L. In RELA 2008, the result of sample A was (10. 523 ±0. 149) μkat/L,and the result of sample B was (10. 551 ±0. 141) μkat/L. The precision of the CK reference method in the year 2006 to 2008 was 0. 92%, 0. 86% and 0. 88% respectively, each of them is less than 1% and the results of ERMs were consistent with the certified value(1. 68 ± 0. 07)μkat/L,which verify the imprecision and accuracy of the reference method. Conclusions All of the results in the continuous three years were in the range of equivalence limits suggested by IFCC. The CK reference method suggested by IFCC has been established and it is getting better.

Objective:To investigate the effect of P53 inhibitors and microtubule inhibitors on nuclear translocation of glucocorticoid receptor in psoriatic epidermal keratinocytes.Methods: Isolate and culture psoriatic and normal epidermal keratinocytes.The keratinocytes were incubated with P53 inhibitors and microtubule inhibitors with or without vascular endothelial growth factor( VEGF) ,and then detected the distribution of GR by indirect immunofluorescence.Results:VEGF induced nuclear trans-location of GR in normal keratinocytes, and the P53 inhibitor restrained VEGF induced nuclear export of GR in normal keratinocytes.The nuclear translocation score of the keratinocytes cultured with VEGF was significantly lower than that of keratinocytes cultured without VEGF(P<0.05).The microtubule inhibitors could completely detained GR of normal epidermal keratinocytes in the cytoplasm,and there′s no significantly increased of the level of GR in the cytoplasm after putting VEGF into the normal epidermal kera-tinocytes.While the microtubule inhibitors and P53 inhibitors co-cultured, there will be a small amount of GR into the keratinocyte nuclei.Conclusion:Microtubule mediated uptake of GR,P53 participated nuclear export of GR.

Objective:To compare the therapeutic effect of immediate breast reconstruction using latissimus dorsi musculocutane-ous flap after modified radical mastectomy with the conventional modified radical surgery of breast cancer. Methods:A retrospec-tive analysis of 224 female patients with Stage 0 to IIIA breast cancer was conducted. The patients were admitted to the Department of Breast Surgery of Liuzhou People's Hospital between November 2009 and July 2012. The cases were divided into two groups accord-ing to different surgical options:immediate breast reconstruction (IBR) and modified radical surgery of the breast (MRSB). After con-trastive analyses of the postoperative complications, cosmetic results, quality of life, local failure rate, distant metastases and mortality rates between the two groups, the therapeutic efficiency of the two surgeries was evaluated. Results:No statistical differences were ob-served in the postoperative complications between the two groups, such as hydrops, skin flap necrosis, limb exercise and shoulder joint motion, drainage time, and starting time of adjuvant therapy (P>0.05). The patients in the IBR group had a better quality of life than those in the MRSB group (P<0.01). The aesthetic evaluation of the breast reconstruction was favorable in 39 cases and secondary in 3 cases, which surpass the evaluation of the patients in the simple MRSB group. No obvious statistical differences were observed in the distant metastasis rate, local recurrence rate, and mortality rate between the two groups (P>0.05). Conclusion:Compared with the tradi-tional MRSB group, the option of IBR after modified radical mastectomy not only achieves similar therapeutic outcomes but also pres-ents advantages such as better aesthetic effect of the reconstructed breast, easy surgical procedures, high safety, improvement of the breast contour outline, and improved quality of life after operation. Therefore, IBR is a safe and available therapeutic method for pa-tients with early breast cancer.
