Objective To investigate the expressions of glucagon-like peptide-1 receptors (GLP-1R) and cytokeratin17 (CK17) in papillary thyroid cancer tissue and clinicopathological significance.Methods The immunohistochemistry and immunoblotting method were employed to detect the expressions of GLP-1R and CK17 in normal thyroid tissues (control group,50 cases) and papillary thyroid cancer tissue (observation group,80 cases).Then the correlation between the expressions of GLP-1R and CK17 with pathological factors of thyroid cancer was analyzed.Results Low expression of GLP-1R was found in 22 cases (44.00 ％) of the control group,while GLP-1R was expressed in 77 cases(96.25 ％) of the observation group,and the difference between both groups was statistically significant(P＜0.01).The expression of CK17 was positive in 8 cases(16.00％) of the control group,while 77 cases(96.25 ％) in the observation group were CK17 expression positive,and the difference between both groups was statistically significant(P＜0.01).The difference between GLP-1 positive expression and clinicopathologic factors had no statistical significance(P＞0.05).The difference between CK17 expression with sex and age had no statistical significance (P＞0.05),and was obviously related with the tumor diameter,clinical stages and cervical node metastasis of thyroid neoplasms(P＜0.05).Conclusion GLP-1R and CK17 all are highly expressed in papillary thyroid cancer tissue and CK17 expression is obviously related with the tumor diameter,clinical stages and cervical node metastasis of papillary thyroid cancer.

Objective To assess the efficacy of ganciclovir to prevent and cure cytomegalovirus (CMV) infection after renal transplantation. Methods We searched PubMed, EMBASE, Cochrane Library, SCI, China Academic Journals Full-text Databases, Chinese Biomedical Literature Database, Chinese Scientific Journals Databases and Chinese Medical Association Journals to collect randomized controlled trials of ganciclovir to prevent and cure CMV infection after renal transplantation (up to June, 2009). Two reviewers extracted data independently using a designed extraction form. The quality of included trials was evaluated according to the Cochrane Handbook. RevMan 5.0 software was used for data analysis. Results Twelve randomized controlled trials were included. The results of meta-analysis showed that: ①Compared with no receive antiviral agents, ganciclovir couldn't lower CMV infection rate and disease rate in 3 months and 6 months after renal transplantation, but could lower CMV disease rate in 12 months. The delay between transplantation and CMV infection was significantly longer. ②Either valaciclovir or ganciclovir could lower CMV infection rate and disease rate after renal transplantation, without statistical difference. ③Compared with acyclovir, ganciclovir could lower CMV disease rate in 6 months after renal transplantation. ④Compared with CMV-IgG and valganciclovir, ganciclovir didn't have statistical difference in decreasing CMV disease rate (P=0.93;P=0.14). Conclusions Longer prophylaxis by ganciclovior may prevent CMV infection after renal transplantation. Its curative effect is similar to valaciclovir, CMV-IgG and valganciclovir, but better than acyclovir.

OBJECTIVETo investigate the role of autophagy in acute lung injury (ALI) caused by multiple trauma in rats via pretreat with 3-methyladenine (3-MA).

METHODSForty-five Sprague-Dawley male rats, with age of 4 months and body weight of 250-300 g,were randomly divided into three groups. In the sham group, the rats received sphenotresia only;in the control group, the rats were made model of femur shaft fracture combined with brain injury, and treated with physiological saline by abdominal cavity at 1 hour before making model; in the 3-MA group, the rats were made model of femur shaft fracture combined with brain injury,and treated with 3-MA of 10 mg/kg by abdominal cavity at 1 hour before making model. Histologic changes and the concentration of related inflammatory factors in the damaged lung tissue were examined at 48 h after opteration, at the same time, the effect of 3-MA on the expression of LC-3 II and Beclin-1 was examined through reverse transcriptase polymerase chain reaction technique (RT-PCR).

RESULTSCompared with sham group, LC-3 II and Beclin-1 level in control group at 48 h after operation were obviously increased (P < 0.01). Compared with control group, LC-3 II and Beclin-1 level in 3-MA group at 48 h after operation were obviously decreased (P < 0.01). Compared with sham group, the level of proinflammatory cytokines (TNF-α and IL-6) in control group obviously enhanced (P < 0.01). Compared with control group, above items in 3-MA group was obviously lower (P < 0.01). Compared with control group,the histopathological damage of lung in 3-MA group obviously reduced (P < 0.01).

CONCLUSIONAutophagy can aggravate the acute lung injury caused by fracture of shaft of femur combined with brain injuries,but 3-MA can reduce tissue damage by inhibiting the autophagy and inflammatory response.

Objective To analyze the consistency of the detection results of glycosylated hemoglobin (HbA1c) by SMART POCT and Hitachi 7180 biochemical analyzers .Methods Firstly the accuracy of HbA1c detected by the SMART POCT and Hita‐chi 7180 biochemical analyzers were evaluated .And then 20 randomly selected samples were tested by both equipments .A relevance analysis between detected data from two equipments was conducted .Results There was a good correlation between the results of the HbA1c detected by two detecting systems ,with the correlation coefficient of r2 =0 .981 1 .Conclusion There is a good consis‐tency in detection results of glycosylated hemoglobin (HbA1c) detected by SM ART POCT and Hitachi 7180 biochemical analyzer .

The object of this study is to preparate the berberine hydrochloride (BBH) resin compound with taste masking effect. We took the BBH as the model drug and Amberlite IRP69 as the drug carriers, uncovered the curve of solubility of BBH in different cosolvent with a certain range of temperature, and then used it to calculate the parameters during the preparation of the complex such as adding quantity of BBH and the reaction temperature. Afterwards, the characteristic and in vitro release experiments were studied to verify the formation and predict the in vivo release behavior of the complex. The results showed that in the condition of using 60% ethanol as a cosolvent and stirring at 50 ℃ for 1 h, the drug loading and drug availability of the complex are at about 35% and 64%, respectively, and has a better taste-masking effect. In this study, a method was provided for preparing a taste-masking preparation of BBH.

Objective:To explore the effect of grief counseling for relieving donor family′s grief. Methods:From September 2012 to February 2015, 180 families of potential organ donors, who met the class III standard of China, were invited to participate in this study. The grief score was evaluated using questionnaire before and after grief counseling. Results:All of 180 potential organ donor′s families had different level of sadness. The grief was significantly reduced after grief counseling and the score was significantly lower than before ( P<0 . 05 ) . Sixty-five cases agreed to donate organ and 60 cases succeed. Conclusion:Grief counseling for potential organ donor′s families could relieve their grief effectively. This method is beneficial for communication of organ donation and pro-moting donation career of China.

Objective To detect and analyze thyroid tumor by two-dimensional sonogram and Doppler parameter, and evaluate the value of high-frequency ultrasound in diagnosing thyroid benign and malignant tumors. Methods The ultrasonic images of 104 thyroid tumor from 80 patients with typical features were collected. Thyroid tumor was classified into benign and malignant nodules, based on the shape, border, or the rear wall echo, echo attenuation loss, internal echo, and microcalcifications in two-dimensional sonogram and systolic blood peak velocity (Vmax) and resistant index (RI) in Doppler examination. The expected results of high frequency ultrasound were compared with pathological results on consistency and error rate. Results Prediction of benign tumor by high frequency ultrasound was 66, and pathology 61, consistency rate of the two was 92.4%. Prediction of malignant lesions was 38, and pathological examination 32, consistency rate of the two was 84.2%. The total coincidence rate was 89.4%(93/104) and the error rate was 11.6%( 11/104). Conclusions The typical features of thyroid tumor on high-frequency ultrasound are helpful in diagnosis of benign or malignant nodules, which is valuable in guiding clinical treatment.
