Objective To explore the CT,clinical,and pathological features of eosinophilic lymphogranuloma(ELG)in head and neck region. Methods CT,clinical,and pathological data of 9 cases of ELG in head and neck region,confirmed by biopsy were retrospectively an-alyzed.Results Parotid gland was lonely involved in 3 cases,and cervical lymph nodes were lonely involved in 2 cases,and they were both involved in 4 cases.All of the patients suffered from painless nodule or mass in head and neck region with peripheral blood eosinophilia.On CT examination,nodular lesions of parotid gland were clear or slightly blurred defined with moderately or obviously homogeneous enhancement,and diffuse mass lesions in parotid gland were ill defined with involvement of surrounding tissue,and heterogenous progressive enhancement.The involved cervical lymph nodes were enlarged with clear boundaries,and moderately or obviously homogeneous enhancement.The pathological findings of ELG included the marked infiltration of eosinophilia,lymphocytic proliferation,lymphatic follicles,variable degrees of fibrosis and vascular proliferation.Conclusion ELG in head and neck region has some CT features,and diagnosis could be suggested combining with the clinical manifestations and peripheral blood eosinophilia. The final diagnosis depends on histopathological examination.

Objective: To observe the clinical effect of sodium nitroprusside and dopamine injected by micro pump for the treatment of refractory heart failure. Methods:One hundred and six cases of patients with refractory heart failure were chosen as the research object, which were cardiac functionⅢ~Ⅳlevel. All patients were treated with sodium nitroprusside and dopamine injected by micro pump. Starting dose of sodium nitroprusside was 6.25 μg/min. At same time pumping dopamine, starting dose of 2 g/kg·min, the dose was increased gradually until blood pressure dropped to 90~100 mm Hg, continuous 7~10 d, the signs and symptoms after treatment and parameters of cardiac function and adverse reactions were observed. Results: 1)In 106 cases of patients with refractory heart failure after treatment, the total effective rate 85.85%(91/106). 2)The heart rate, blood pressure, cardiothoracic ratio, left ventricular short axis reduced rate,cardiac output, each index of cardiac,indexes of left ventricular ejection fraction were improved significantly after treatment. Conclusion:The clinical effect for the treatment of refractory heart failure by using the micro pump injection of small doses of sodium nitroprusside combined dopamine would be obvious, have less adverse reactions, worthy of clinical popularization and application.

Objective: To explore the coping strategies of students of military medical university, and the relationship between coping strategies and mental health. Methods: 4786 students of military medical university were assessed with the Simplified Coping Style and SCL-90. Results: 30～40% of the student chose active strategies when facing stresses. Fewer students adopt negative strategies (2～38%). The SCL-90 score of the students of military medical university were lower than students of other military schools. Positive coping strategies were associated with less SCL-90 score (fewer somatic and mental discomfort).Conclusion:Coping strategies are associated with mental health in student of military medical university.

Objective To explore the characteristics of semantic priming effects in Chinese words with different association strength in patients with aphasia by auditory stimulation.Method Stimulus-response word pairs with different association strength including strong,moderate,weak,and no association categories were chosen from word association thesaurus as experiment materials.Both patients with aphasia(n=11)and normal subjects (n=16)were requested to finish an auditory lexical decision task for target words.Semantic priming effects were investigated by means of measuring reaction time(RT)and error rate of each word-pair.Results In patients with aphasia and normal subjects,the mean RTs were significantly shorter in strong,moderate and weak association strength words than in no association strength words(patients with aphasia(1270.20±47.70)ms,(1340.50±266.25)ms,(1429.70±317.07)ms vs(1549.00±325.87)ms,P＜0.05 and normal subjects(1140.2±274.48)ms,(1196.50±284.06)ms,(1262.10±274.31)ms vs(1391.20±315.68)ms,P＜0.05).In strong,moderate,and no association strength words,the mean RTs were no significant differences between two groups.In the weak association strength words,mean RTs were significantly longer in patients with aphasia than in normal subjects((1429.70±317.07)ms vs(1262.10±274.31)ms,P＜0.05).In two groups,mean error rates were significantly less in strong,moderate and weak association strength words than in no association strength words(patients with aphasia:7.73±6.07,4.55±7.23,6.82±8.15 vs 14.09±12.41,P＜0.05 and normal subjects:3.44±4.37,2.81±3.64,5.31±5.91 vs 10.94±11.14,P＜0.05).However,in strong association strength words,mean error rates were significantly higher in patients with aphasia than in normal subjects(7.73±6.07 vs 3.44±4.37,P＜0.05).In moderate,weak and no association strength words,there were no significant differences between two groups.Conclusion The patients with aphasia follow gradient of the association strength words like normal subjects and have semantic priming effects in the strong,moderate association strength words.

Objective To establish and assess the high-birth-weight offspring model of the diabetic rat induced by stueptozotocin,and the long-term metabolic impact of maternal hyperglycemia of those offsprings.Methods Streptozotocin (STZ,25 mg/kg) was given to Wistar rats (G group,n =14) once intraperitoneally to induce maternal hyperglycemia model (blood glucose between 10-20 mmol/L),and there still had a number of rats defined as severe hyperglycemia model group (SG group,n =5).The Control group (C group,n =7) were given the same volume citrate buffer solution.The body weight and blood glucose were recorded,and the lavaging glucose tolerance test (LGTT) was performed by a glucose meter in the gestation.The offsprings were corresponding allocated into 2 groups,and the birth weight were recorded.All the offsprings were observated body weight,blood glucose blood pressure (male rats only),and so on.Results (1) The blood glucose of G group (16.8 ±5.4 mmol/L) and SG group (20.5 ±5.6 mmol/L) were increased significantly as compared with C group (7.0 ± 1.4 mmol/L) 5 days after the model was established (P ＜ 0.01) ; and the average blood glucose of G group (16.6 ± 3.4 mmol/L) and SG group (23.8 ± 1.5 mmol/L) increased too as comparede with C group (5.8 ± 1.1 mmol/L),the difference was significance according to statistics (P ＜ 0.01).(2) According to the LGTT result,which operationed on generation day 4 and day 10,the blood glucose of every time point of G group were increased significantly as compared with C group (P ＜ 0.01).(3) The male and female birth weight of G group was remarkably higher than the C group and the SG group (P ＜ 0.05),and the blood glucose of SG /G/C group was (6.5 ±1.2) mmol/L,(4.1 ± 0.8) mmol/L,(4.1 ± 0.8) mmol/L respectively,according to the statistics results,the difference between SG group and G/C group respectively both remarkable (P ＜ 0.05).(4) The body weight,Lee's index,fat weight,and the fat weight of mass ratio in C group mother rats after lactation presented dressed compared with the SG group (P ＜ 0.05),and so as to the G group compared with the SG group (P ＜ 0.05).(5) In the female offsprings of G group,the birth weight was remarkably increased compared with the C group (P ＜ 0.05) ; the body weight of the female offsprings presented an increased trend compared with the C group since the 12 weeks,but had no statistical significance; there were significant differences of body weight between G group and C group since 15 weeks (P ＜ 0.05),and the trend kept up until 26 weeks; in the male offsprings of G group,the body weight on birth day and 4 weeks had a marked rise compared with the C group (P ＜ 0.05) ; and from then on,the body weight of the male offsprings presented an increased trend compared with the C group,but had no statistical significance until 26 weeks (P＞0.05).(6) In G group,the blood glucose on 30 min and 60 min of LGTT in female offsprings were increased than the C group since 20 weeks (P ＜ 0.05) ; the blood glucose of LGTT (30 min) still had a marked rise until 24 weeks (P ＜ 0.05) ; in G group,the blood glucose on 30 min of LGTT in male offsprings was remarkably incrcascd than the C group since 16 weeks (P ＜0.05) ; the blood glucose of LGTT (30 min) still had a marked rise until 24 weeks (P ＜ 0.05).(7) The blood pressure of male offsprings in G group had a marked rise on 12 weeks compared with the C group (P ＜ 0.05) ; from then on the blood pressure of G group kept up a rise trend until 26 weeks,but had no statistical significance (P ＞0.05).Conclusion The diabetic high-birth-weight rat model could be duplicated with STZ (25 mg/kg) once intrapertoneally on the first day of gestation,which were observed some evidently metabolic changes in weight,glucose tolerance and blood pressure.These results could represent an forward step in the clinical study of human gestational diabetes mellitus and their macrosomia babies,which may suffer some metabolic disease in their later life.

Objective To observe the therapeutic efficacy of acupuncture at the thirteen ghost points in treating postpartum depression and its effect on the quality of life. Methods Sixty patients with postpartum depression were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupuncture at the thirteen ghost points, while the control group was by oral administration of Fluoxetine. The Hamilton Rating Scale for Depression (HAMD) and the Short-Form (36) Health Survey (SF-36) were compared before and after intervention. Results The HMAD score was significantly changed in both groups after intervention (P＜0.05). There was a significant difference in comparing the HAMD score between the two groups after intervention (P＜0.05). There were significant differences in comparing the post-treatment bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), mental health (MH), and health transition (HT) between the two groups (P＜0.05). Conclusion Acupuncture at the thirteen ghost points can effectively improve the postpartum depression and the quality of life.

Objective To investigate the expression of proinflammatory cytokine interleukin-17(IL-17) and complement cleavage fragment C5a and the regulation effect of C5a on the expression of IL-17 during renal allograft rejection .Methods The frequency of IL-17+ T cell in peripheral blood and the expression of IL-17 in renal tubular epithelial cells (HK2) after C5a stimulation in renal transplant recipients were measured by flow cytometry and the changes of serum C5a level was detected by ELISA ,respectively .Im-munohistochemistry was applied to detect and compare the expression of IL-17 and the deposition of C5b-9 in normal renal tissues and renal tissues with allograft rejection .The difference of IL-17 expression in HK2 cells before and after the recombinant C5a stimulation was detected by immunocytochemistry .Results Both the percentage of IL-17+ T cells and serum C5a levels were sig-nificantly increased after the allogeneic renal transplantation .Compared with normal renal tissues ,both the deposition of C5b-9 and the IL-17 expression in renal tissues with allograft rejection was remarkably up-regulated ,which showed the positive correlation be-tween them .The expression of IL-17 in HK2 was obviously up-regulated by the recombinant C5a stimulation .Conclusion C5a may positively regulate the expression of IL-17 by tubular epithelial cells during the renal allograft rejection .

Objective To evaluate the impact of chronic hepatitis B virus (HBV) infection on the outcome following resection for intrahepatic cholangiocarcinoma (ICC) patients.Methods The clinicpathological data of 60 consecutive operated ICC patients were collected.These patients were divided into group A with HBV infection,represented by serum positive hepatitis B surface antigen (HBsAg),group B with hepatitis B surface antibody (HBsAb) positive,and group C with all serum marker of HBV negative.The overall survival rate was evaluated.Results The 1-and 3-year overall survival rate and median survival of three groups were 50％ vs 53％ vs 29％ ; 22％ vs 18％ vs O; and 12.0 m vs 12.0 m vs 6 m,respectively.The difference was statistically significant(P =0.037).Multivariate analyses revealed that the preoperative serum level of TIBL,tumor location,HBV infection or injection of hepatitis B vaccine,hepatolithiasis and adjuvant chemotherapy were related to the prognosis.Conclusions HBV infection or injection of hepatitis B vaccine is favorable independent factor for prognosis of patients with intrahepatic cholangiocarcinoma after resection.

OBJECTIVE: To investigate the expression and clinical significance of ZEB2 and E-cadherin mRNA and protein in nasopharyngeal carcinoma (NPC) tissues. METHOD: The expressions of ZEB2 and Ecadherin in 39 cases of NPC tissue and 12 cases of nasopharyngeal inflammation tissue were detected by Real-time PCR method and immunohistochemical technique. To assess their correlations with clinicopathological parameters of NPC and the interrelationship between them. RESULT: Both the expression of ZEB2 mRNA and protein were higher in NPC tissues than that in inflammation tissues (P < 0.05). Abnormal expression of ZEB2 mRNA and protein in NPC were significantly associated to N stage and clinic stage (P < 0.05), but the difference in expression between the different gender, age and T stage were not statistically significant (P > 0.05). Both the expression of Ecadherin mRNA and protein were higher in NPC tissues than that in inflammation tissues (P < 0.05). Abnormal expression of Ecadherin mRNA and protein in NPC were significantly associated to N stage (P < 0.05), but the different expression between the different gender, age, T stage and clinic stage were not statistically significant (P > 0.05). In NPC tissues, the expression of ZEB2 mRNA was negative correlated with the expression of E-cadherin mRNA (r = -0.367, P < 0.05). The expression of ZEB1 protein was negative correlated with the expression of E-cadherin protein (r = -0.322, P < 0.05), the differences were both statistically significant. CONCLUSION The expression of ZEB2 was up-regulated in NPC, while the expression of E-cadherin was down-regulated, their expression was significantly negative correlated, and might be associated with metastasis of NPC, ZEB2 may promote the invasion and metastasis of NPC by inhibiting the expression of E-cadherin.
