Objective Toinvestigatethecorrelationofsmallvesseldisease(CSVD)causedacute lacunarinfarctionandurinemicroalbumin.Methods Theclinicaldataof136patientswithacutelacunar infarction admitted to the Department of Neurology,Shengjing Hospital of China Medical University from November 2012 to April 2014 were analyzed retrospectively. They were divided into either a CSVD group (n=72)or a cerebral large vessel disease (CLVD)group (n=64)according to their carotid artery color Doppler ultrasound and head magnetic resonance angiography findings. The levels of urinary microalbumin in both groups were observed and compared. SAS 9. 1 software was used to conduct statistic analysis. A Logistic regression analysis was used to determine the independent risk factors for CSVD caused acute lacunarinfarction.Results TheconcentrationofurinemicroalbuminoftheCSVDgroup(22±13mg/L) was significantly lower than (29 ± 14 mg/L)that of the CLVD group. There was significant difference (P<0.05). There was significant difference in the increased urine microalbumin levels between the CSVD group and the CLVD group (P<0. 01). There was an increasing trend for the proportion of patients with urine microalbumin concentration 10- <30 mg/L (56. 9%[41/72])in the CSVD group compared with the CLVD group (26. 6%[17/64]). Logistic regression analysis showed that the slightly increased microalbuminuria was associated with CSVD caused acute lacunar infarction (OR,3. 130,95%CI 1. 481-6.618;P<0.01).Conclusion Theslightlyincreasedmicroalbuminuriaisanindependentriskfactorfor CSVD caused acute lacunar infarction.

Objective:To explore how coping style and social support influence the quality of life in patients with impaired glucose tolerance, which act respectively as the internal and external mediating ways. Methods:A total of 283 patients with impaired glucose tolerance from 6 Three-A hospitals in China were surveyed with self-rating anxiety scale, self-rating depression scale, trait coping style questionnaire, social support scale, and WHOQOL-BREF.
Results:Biographic data failed to predict the quality of life in patients with impaired glucose tolerance, while anxiety, depression, social support and coping style significantly influenced their quality of life.
Conclusion:The fact that emotional disorder, social support and coping style influence the quality of life in patients with type 2 diabetes also exists in patients with impaired glucose tolerance.

Objective To investigate the expression and significance of death receptor 4(DR4) and DR5 in human craniopharyngioma.Methods The expression of DR4 and DR5 was determined by immunohistochemistry and in situ hybridization in 28 samples of craniopharyngioma and 25 samples of normal brain tissue.Results With low expression in partial normal brain tissue,DR was expressed highly in all of the craniopharyngioma samples.High DR expression in craniopharyngioma tissue differed from low DR expression in normal brain tissue(P0.05).Conclusions High DR expression is prevalent in craniopharyngioma tissue.This may contribute to the apoptosis-induced therapy of craniopharyngioma.The control of DR expression lays in protein level.This may contribute to the selective induced-apoptosis of tumor necrosis factor-related apoptosis-induced ligand.

Objective To explore whether there were abnormalities of behavioral tests and CNV-like potential in stressed rats following repeatedly forced swim stress.Methods Forty male rats were randomly divided into 4 groups: the control groups (Control-1 and Control-2) and the stress groups ( Stress-1 and Stress-2).Rats in stress groups were administered to repeatedly forced swim 7 or 14 days respectively.Body weight gain, saccharin preference test and open field test were performed.After being anesthetized with urethane, CNV-like potentials were elicited by condition-test stimulus.Results Results of behavioral tests displayed less body weights (F =253.60, P＜0.001 ) and less saccharine solution intake (F= 13.67, P=0.001 ) in stressed group rats and significant effects of stress on the number of crossing squares, the duration of rearing and the number of grooming in open field test.CNV amplitudes were lower in the stressed rats than those in control (F=21.312, P＜0.01 ).Conclusion This study provides an important evidence of changes of CNV-like potential in depressed rats following repeatedly forced swim stress.Based on this study, ER Ps should be taken into consideration and applied as the useful tools in the research work of depressed animal models.

OBJECTIVETo investigate the inhibitory effect of bone marrow mesenchymal stem cells (BMSCs) on E coliinduced prostatitis in rats.

METHODSBMSCs were isolated, cultured and amplified by the attached choice method. Fifty SD rats were randomized into five groups of equal number: normal control, acute bacterial prostatitis (ABP) , chronic bacterial prostatitis (CBP), ABP + BMSCs, and CBP + BMSCs, and the animals in the latter four groups were injected with E. coli into both sides of the prostate under ultrasound guidance for 1 - 14 days to induce ABP and for 4 - 12 weeks to induce CBP. The control rats were injected with the same amount of PBS. Two weeks after injection of BMSCs into the prostates, pathomorphological changes in the prostate were observed under the light microscope and the mRNA and protein levels of IL-1β and TNF-α determined by RT-PCR and ELISA, respectively, followed by statistical analysis with SPSS 18.0.

RESULTSHistopathological evaluation showed typical pathological inflammatory changes in the prostates of the rats in the ABP and CBP groups, including glandular structural changes, interstitial edema, inflammatory cell infiltration, and fibrous hyperplasia, which were all remarkably relieved after treated with BMSCs. The mRNA and protein levels of IL-β ([0.829 ± 0.121] and [271.75 ± 90.59] pg/ml) and TNF-α ([0.913 ± 0. 094] and [105.78 ± 19. 05] pg/ml) in the ABP and those of IL-1β ([0. 975 ± 0. 114] and [265. 31 ± 71. 34] pg/ml) and TNF-α ([0. 886 ± 0. 084] and [107. 45 ± 26. 11 ] pg/ml) in the CBP groups were significantly higher than those in the control rats ([0. 342 ± 0.087] and [45.76 17. 99] pg/ml, P <0. 05); ([0.247 ± 0.054] and ([19.42 ± 7. 75] pg/ml, P <0. 01) as well as than those in the ABP + BMSCs ([0. 433 ± 0. 072] and [51. 34 ± 22. 13] pg/ml, P < 0. 05 ) ; ( [0. 313 ± 0. 076] and [28. 38 ± 8. 78] pg/ml, P < 0. 01) and the CBP + BMSCs group ([0.396 ± 0.064] and [56.37 ± 21.22] pg/ml, P <0.05); ([0.417 ± 0.068] and [29.21 ± 10.22] pg/ml, P <0.01).

CONCLUSIONInjection of BMSCs can reduce E coli-induced prostatic inflammation reaction, which.may be associated with its reduction of inflammatory cell infiltration and the expressions of IL-1β and TNF-α in the prostate tissue.

Objective To analyze the effect of high and low dose radiation on the expressions of Th1,Th2 and Th3 /Tr1 related-genes in mice thymocytes and investigate the possible underlying molecular mechanism.Methods ICR mice were randomly divided into low-dose group (0.075 Gy),high-dose group (2.0 Gy) and sham-control group.The mouse thymus tissue was extracted at 16 hours after irradiation and the expressions of Th1-Th2-Th3 related genes were measured by PCR array.Results Eight genes were up-regulated and five genes were down-regulated after low dose radiation (0.075 Gy);while 54 genes were up-regulated and three genes were down-regulated after high dose (2.0 Gy) radiation.These genes included Th1 cell related genes,Th2 cell related genes,Th3/Tr1 cell related genes,Th1/Th2 immune response genes and transcription factor related genes.Low dose radiation induced up-regulation of Stat4 and Socs1 of genes related to the Th1 cells,and it induced down-regulation of IL-4ra,Cebpb,Gata3 and Tgfb3 associated with Th2 and Th3 cells,which lead to Sftpd genes up-regulation of Th1 immune response eventually.The high dose radiation up-regulated all of Th1,Th2 and Th3/Tr related genes and also enhanced the expressions of Cd86,IL-18,IL-10 and Irf4 genes related to Th2 immune response,but it did not alter the gene expression of Th1 immune response.Conclusions Low-dose radiation induces Th1-type immune response,while high doses radiation triggers Th2 type immune response.

OBJECTIVE: To investigate the expression of Bax and PHF20 in laryngeal squamous cell carcinoma (LSCC)and to discuss their relevance and the roles in carcinogenesis and development in LSCC. METHOD: The expressions of Bax and PHF20 in the LSCC tissues and normal mucosa tissues adjacent to carcinoma were detected by SP immunohistochemistry assay. The relationship between the expressions of Bax and PHF20 and the clinicopathological characteristics including clinical stage, pathological type, histological grade and lymph node metastasis in LSCC were analyzed according to the clinical data. RESULT: (1) The expressions of Bax and PHF20 were both significantly lower in the LSCC tissue than that in the normal laryngeal tissue (P < 0.01). (2) In clinical stage grouping, there were no statistical differences of the quantity and positive rate of Bax and PHF20 expressions among supraglottic, glottic and subglottic LSCC (P > 0.05). In histological differentiation grouping, the quantity and positive rate of Bax and PHF20 expressions decreased significantly in poorly differentiated LSCC compared with the well and moderately differentiated LSCCs (P < 0.01, P < 0.05, respectively). In T stage grouping, the quantity and positive rate of Bax and PHF20 expressions were both significantly higher in T1 + T2 compared with T3 +T4 (both P < 0.01). In addition, the quantity and positive rate of Bax and PHF20 expressions were both significantly higher in LSCC with lymph node metastasis compared to that without lymph node metastasis (both P < 0.01). CONCLUSION The lack of Bax and PHF20 might contribute to the carcinogenesis and development in LSCC. The positive expression of Bax and PHF20 maybe relative to T term degree, differentiation degree and lymphamatic metastasis of LSCC.
