Objective To investigate the relation between the expression of Caspase recruitment domain-containing membrane-associated guanylate kinase protein 1 (CARMA1),clinicopathological features of gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma,diffuse large B cell lymphoma (DLBCL),and Helicobacter pylori (H.pylori) infection.Methods From January 1999 to March 2011,34 patients with DLBCL and 20 patients with MALT lymphoma were selected,and at same period 21 cases with reactive hyperplasia of gastrointestinal lymphoid tissue were enrolled in as control.The expression of CARMA1,Ki-67 and cytotoxin-associated gene A (CagA) at protein level were examined by immunohistochemistry.The relative expression quantity of CARMA1 mRNA was detected by real-time polymerase chain reaction (PCR).The condition of H.pylori infection in 25 gastric lymphoma and 10 controls was detected by methylene boric acid and blue staining or semi-nested PCR.Chi-square test was used for counting data analysis,t test for measurement data.Multivariate COX regression analysis was implemented for survival analysis.Survival curve was drawn by Kaplan-Meier method and analyzed by Log-rank test.Results The relative expression quantity of CARMA1 mRNA of 28 patients with DLBLC (3.073±1.846) was higher than that of 14 patients with MALT lymphoma,and the difference was statistically significant (F 0.975,P＜ 0.05).The positive rate of CARMA1 expression at protein level of gastrointestinal lymphoma group (75.9 ％,41/54) was higher than that of control group (47.6％,10/21),and the difference was statistically significant (x2 =5.568,P＜0.05),and the positive rate of CARMA1 expression of MALT lymphoma group (11/20) was lower than that of DLBCL group (88.2％,30/34),and the difference was statistically significant (x2 =5.900,P＜0.05).Among 42 patients with gastrointestinal lymphoma who received surgery,the relative expression quantity of CARMA1 mRNA in cases with high proliferation (2.885±1.837) was higher than that in cases with low proliferation.The expression of CARMA1 mRNA in the cases at advanced stage of the disease (4.416± 1.010) was higher than that in cases at early stage,and the difference was statistically significant (F=3.317 and 2.972,both P＜0.05).Among 54 patients with gastrointestinal lymphoma,the positive rate of CARMA1 expression at protein level of patients with high proliferation (88.6％,31/35) was higher that that of patients with low proliferation (10/19),and the difference was statistically significant (x22 ＝ 6.847,P＜0.05).There were no significant differences in relative expression quantity of CARMA1 mRNA and the positive rate of CARMA1 expression at protein level between 11 gastric lymphoma patients without H.pylori infection and 14 gastric lymphoma patients with H.pylori infection (both P＞0.05).The positive rate of CARMA1 expression at protein level of CagA positive and CagA negative H.pylori infected gastric lymphoma patients was 11/11 and 2/3.The expression of CARMA1 at protein level was correlated with the prognosis of gastrointestinal lymphoma (RR＝4.160,P＜0.05).In the 29 cases of patients with gastrointestinal MALT lymphoma and 18 cases of patients with DLBCL who were followed up,the survival situation of gastrointestinal lymphoma patients with CARMA1 positive expression rate over 50％ was worse than that of patients with the rate less than 50％,and the difference was statistically significant (x2=5.383 and 4.028,both P＜0.05).Conclusions CARMA1 might be involved in the pathogenesis and progression of MALT and DLBCL; and it might be a related factor of poor prognosis.There was no correlation between the expression of CARMA1 and H.pylori infection in these two lymphomas.

OBJECTIVE: To investigate the correlation of laryngeal squamous cell carcinoma (LSCC) and precancerous lesion with HPV infection subtypes and possible clinical relationship. METHOD: Eighty-three cases in paraffin embedded tissues were detected with thirty seven HPV subtypes by flow-through hybridization and gene chip (HybriMax), including 31 cases of laryngeal squamous cell carcinoma, 52 cases of precancerous lesions (29 cases of vocal cord leukoplakia and 23 cases of laryngeal papilloma), and 36 cases of vocal cord polyp as normal vocal mucosa were used as control. RESULT: The total positive rate of HPV was 19.4% in the group of laryngeal squamous cell carcinoma (6/31), 0 in vocal cord leukoplakia, 65.2% in laryngeal papilloma (15/23), and the control group were all negative, HPV virus subtype of HPV-positive laryngeal squamous cell carcinoma were all high-risk HPV16; and there were 6 HPV virus subtypes in laryngeal papilloma (8: HPV6,4: HPV52, 1: HPV11, 1: HPV18, 2: HPV45, 3: HPV16), individual mixing two or more subtypes infection. HPV infection of laryngeal squamous cell carcinoma and precancerous lesions has no statistically significant difference according to gender, high low-risk subtypes. CONCLUSION HPV infection related to laryngeal squamous cell carcinoma and precancerous lesions, but no significant correlation with the subtype distribution of high and low risk; HPV detection is making positive sense to clinical diagnosis of laryngeal carcinoma and precancerous lesions as well as the development of specific HPV subtype vaccine.

Objective To compare the biological characteristics of several different anxiety rat models established by different methods of stress at different time points and provide experimental basis for the most appropriate modeling methods .Methods 60 rats were randomly divided into normal , empty bottle stress , chronic emotional stress ( CES ) group, restraint stress for 3h, 6h, and modeling respectively .In the experimental 7 d, 14 d, 21 d, elevated plus maze and fear condition system was used to test anxiety-like behavior in rats , open field test to study anxiety or depression-like behavior , forced swimming test was used to detect depression-like behavior in rats , and using the Elisa test kit to detect the contents of 5-HT, DA in the hippocampus in rats .Results Anxiety-like behavioral test results showed that rats in empty bottle stress, CES, 6 h restraint stress group started to have anxiety-like behavior since 14 d, then anxiety-like behavior was becoming increasingly apparent .Forced swimming test results showed that immobility time in 6 h restraint rats was significantly increased in the first 7 d(P <0.05).Meanwhile, compared with control group, hippocampal 5-HT, DA contents in empty bottle stress and CES rats increased significantly since 14 d.Conclusions Among several stress methods established anxiety model , anxiety-like behavior in 3 h restraint stress was not obvious; 6 h restraint stress exhibited a depression-like behavior in the forced swimming test might be due to prolonged stress .Empty bottle stress and CES can successfully establish the anxiety rat model , and the anxiety behavior of the rats have some differences . Corresponding model methods can be selected according to different experimental purposes .

Objective To study the content of monoamine neurotransmitters and neurotrophic factor in the hippocampus, amygdala and prefrontal cortex in anxious depression rats, and explore the possible pathogenesis.Methods 60 SD rats were randomly divided into normal group, vehicle group, anxiety group, depression group, and anxious depression group, 12 rats in each group.Chronic restraint stress combined with corticosterone injection was used to establish anxiety and depression model, the modeling time was 21 d.After modeling, elevated plus maze test, open field test, and forced swimming test were used to evaluate the anxiety and depression-like behavior, HPLC-ECD was used to detect the content of 5-HT, NE, and DA in the hippocampus, amygdala, and prefrontal cortex of rats.Western-blotting was used to detect the expression of BDNF and NT-3 in rats.Results Rats in anxious depression model group were comparable to the anxiety group in time and frequency entering open arm time, and number of locomotor activity in open field, and it had a significant difference when compared with the control and depression groups (P<0.01 or P<0.05).Immobile time in anxious depression model rats was increased significantly when compared with the control and anxiety groups (P<0.01).Meanwhile, compared with the control group, 5-HT in hippocampus and 5-HT, NE in amygdala or prefrontal cortex were significantly decreased in the depressive rats with anxiety (P<0.01 or P<0.05).Moreover, the content of BDNF and NT-3 was significantly decreased in each brain regions compared with the control group (P<0.01 or P<0.05), and BDNF levels were obviously decreased compared with the anxiety group (P<0.05).Conclusions Rats of anxious depression have significant anxiety and depression-like behaviors.Its mechanism may be associated with the down-regulation of monoamine neurotransmitters and neurotrophic factors BDNF and NT-3 in hippocampus, amygdala, and prefrontal cortex region.

Objective To investigate the regulating effects of Zuogui Jiangtang Jieyu Formula (ZJJF) on Bcl-2, Bax and Caspase-8 in hippocampus neuron damage in diabetes mellitus with depression (DD). Methods Hippocampal neurons from 18 d pregnant rats were primitively cultivated, and then combination of glucose and corticosterone was used to construct DD simulation environment. Cultivated hippocampal neurons were randomly divided into normal group, blank serum group, model group, positive medicine (metformin+fluoxetine) serum group and to-be-tested medicine (ZJJF) serum group. Normal group and model group were given same amount culture medium, while other group were given relevant amont of 10％ medicine serum or blank serum. After modeling intervention for 18 h,Hoechst staining was used to detect the apoptosis of hippocampal neurons. The expression of Bcl-2, Bax and Caspase-8 was detected by high content analysis. Results Compared with the control group, hippocampal neuron dendrites ruptured or decreased, neural network connection decreased, cells showed significant staining, broken, uneven distribution of light spots, the expression of Bcl-2 protein decreased significantly (P<0.05), but Bax and Caspase-8 were increased (P<0.05, P<0.01). Compared with the model group, hippocampal neurons in both positive medicine serum group and ZJJF serum group gradually recovered. Hoechst staining showed that the nuclei were significantly homogenized, local highlights were significantly reduced, Bcl-2 protein expression levels were significantly increased (P<0.05, P<0.01), while Bax and Caspase-8 were obviously down-regulated (P<0.05, P<0.01). Conclusion ZJJF has protective effects on hippocampal neurons in DD of model rats, and its mechanism is related to regulating the expression of Bcl-2, Bax and Caspase-8 in hippocampus neuron.

Objective To investigate the intermediary and regulating effect of self?esteem on per?ceived stress and training burnout among accelerated plateau soldiers. Methods A total of 700 accelerated plateau soldiers were investigated which were chosen by a random cluster sampling method,and assessed by the Perceived Stress Scale, Self?esteem Scale and Self?compiled Soldiers' Training Burnout Questionnaire. Results ( 1) The total score of training burnout,the score of physical and mental exhaustion and the score of training alienated among soldiers who had a history of training injury (27.85±5.80,14.89±3.46 and 6.89± 2.26,respectively) were significantly higher than those of soldiers who didn't have a history of training injury (25.05±5.12,12.68±3.25 and 6.16±2.78,respectively),and the differences were significant ( t= 4.321, 5.764,2.825,all P<0.01). The total score of training burnout,the score of physical and mental exhaustion and the score of training alienated among soldiers who had a high training expectation were higher than those of soldiers who didn't have a high training expectation,and the differences were significant (P<0.01). (2) Among accelerated plateau soldiers,training burnout showed significantly positive correlation with perceived stress ( r=0.323, P<0.01),and significantly negative correlation with self?esteem ( r=-0.409, P<0.01). (3) The intermediary role of self?esteem between perceived stress and training burnout was remarkable (P<0.01) ,which accounted for 33.8% of the total effect,and self?esteem also had a regulating effect (P<0.05) . Conclusion Radical plateau soldiers have remarkable differences due to the history of training injury or training expectations,and self?esteem has partial intermediary and regulating effect between perceived stress and training burnout.
