Objective The aim of this study is to investigate the expression of Survivin in laryngeal car-cinoma and to elucidate the relationship between cell proliferation and the expression of Survivin .Methods The expression and DNA quantification of Survivin in 63 cases of laryngeal carcinoma and 15 cases of normal laryngeal tissues were detected by immunohistochemical staining ( SP) and flow cytometry .Results Forty-five sections of laryngeal carcinoma were positive for survivin as determined by immunohistochemical staining ,but Survivin was undetected in normal laryngeal tissues .The intensity of Survivin expression was significantly increased with tumor differentiation and lymph node metastasis (P<0.05),and was negatively correlated with age ,gender and clinical stage of patients(P>0.05).High DNA index(DI)and proliferation index(PI)were detected in laryngeal carcino-ma(P<0.05),and PI was positively correlated with expression of Survivin (P<0.05).Conclusion Survivin overexpression triggers laryngeal carcinoma cell hyperproliferation ,especially in development of laryngeal carcino-ma.These data identify Survivin as an important target in laryngeal carcinoma and provide a translational pathway for developing new therapies against this target .

Objective In order to investigate the relationship between hearing loss and diabetic peripheral neuropathy( DPN ) via comparing the pure tone thresholds and vibration perception threshold(VPT) in type 2 diabetic patients and control person without diabetes. Methods 173 subjects including 138 type 2 diabetic patients(DM)and 35 non-diabetes controls were examined for VPT and hearing threshold. Nerve conducting velocity ( NCV )including sensory nerve conducting velocity( SCV )and motorial nerve conducting velocity( MCV )of diabetic patients were determined. The participants were divided into three groups: control group (n = 35 ), DM group without peripheral neuropathy( non-PN group, n = 74 ), and DM group complicated with peripheral neuropathy (PN group,n = 64 ). The clinical characteristics, biochemical parameters , the incidence of sensorineural hearing loss ( SNHL),pure tone threshold, and VPT were compared among three groups. At last, the relationship between hearing thresholds and NCV were analyzed. Results The incidence of hearing impairment of sensorineural type was 29.69% in PN group, which was significantly higher than that of non-PN group( 17.57% )and control group( 17. 14% ). There was significant differences in age, duration of diabetes, glycolated hemoglobin (HbA1c), glycolated serum albumin ( GA), Fasting blood glucose( FPG), 2h postprandial blood glucose( PPG), VPT, and hearing threshold among the three groups( all P<0. 05 ). The value of hearing threshold increased significantly( all P<0. 05 ) in 3 VPT subgroups with VPT≤ 15 V, VPT 16-25 V, and VPT >25 V. The Spearman correlation analysis showed median NCV was negatively correlated with hearing threshold on 1.00, 2.00, 4. 00, and 8. 00 kHz ( All P < 0. 05 ). The logistic regression analysis indicated that the age( regression coefficient =0. 088, P<0. 01 ) was the independent risk factor of SNHL, median nerve MCV ( regression coefficient = -0. 135, P = 0. 046 ) was the important influencing factor of SNHL. Conclusion Diabetic patients are more likely to suffer from impaired middle-frequency and high-frequency hearing, DPN in patients is often complicated with hearing impairment. Age and median nerve MCV were major risk factors of SNHL in diabetic patients.

This paper introduces the nursing care of two children with type 1 diabetes during continuous glucose monitoring. In addition to psychological care,diet instruction and insulin therapy,the nurses actively communicated with the children and their parents,introduced the principle and advantages of continuous glucose monitoring system (CGMS) to promote the children and parents to cooperate with the medical staff. Moreover,the insert site of CGMS was changed from inferior abdomen to up-per lateral buttock according to the physiological character of children. As a result,the CGMS was completed successfully in the 2 eases,which provided reliable reference for the regulation of treatment plan.

Objective:To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.

Objective To study the immune regulatory effect of natural killer cell(NKT) in the early stage of murine liver injury induced by type 5 adenovirus(Ad5). Methods Animal models were con-structed by injected C57BL/6 mice with 1.5×109-3×109 PFU Ad5 into the tail vein. Liver injury of mouse at day 0, 1, 2, 3, 4, 5 after infection was determined by HE staining and serum ALT/AST(alanine amin-otransferase/aspartate aminotransferase) level. Flow cytometry analysis was used to measure the proportion of lymphocytes, expression of Fas/FasL on the surface of NKT cells and level of IL-4, IFN-γ/in NKT cell plasma in the infected mouse liver. RT-PCR was applied to semi-quantify the chemokines and their receptors mRNA in infected mouse liver. Results NKT cells of mouse increased significantly at day 1 after infected with high titer Ads(3×109 PFU), expression of FasL on NKT cell and plasma IL-4, IFN-γ/level in NKT cells were also up-regulated, hence the obviously infiltration of lymphocytes in routine liver. Comparing with high titer Ads infection, low titer Ads infection (1.5×109 PFU) lead to little change of NKT cell proper-tion, and fewer infiltration of lymphocytes in murine liver. Hepatic chemokine RANTES, 1P-10, and MIP-1β mRNA expression in C57BL/6 was up-regulated 2 d after intravenous administration of 3×109 PFU Ad5. Corresponding chemokine receptor CCR5, CCR1, CXCR3 mRNA expression was up-regulated 3 d after in-fection. Conclusion NKT cells play an important role in lymphocytes recruitment into the liver of mouse in-fected with AdS, which may relate to up-regulatio of the plasma IL-4, IFN-γ level and expression of FasL of NKT cells, therefore facilitating the production of chemokines, e.g. IP-10 and Mig.
