Objective: To study depression of patients with Grave's disease and the therapeutic effect of Paroxetine (antidepressant). Method: 82 patients with first onset Grave's disease were collected and 52 of them had depression. The depressive patients were divided into Paroxetine and control group. All cases had the same anti-hyperthyroidism treatment. Result: 63.4% (52/82) patients with first onset Grave's disease had depression before Paroxetine treatment. After 4 weeks and 8 weeks treatment, Paroxetine group had greater decrease in FT3 and FT4, and lower scores of SDS and SAS than control group (p＜0.01). Conclusion: Paroxetine does enhance the therapeutic effect of anti-hyperthyroidism, as well as improving depression of patients with first-onset Grave's disease.

The present study were to identify a dose-response relationship and study the histologic correlates. Group A : The rabbit's iliac segments of normal control,were performed in radiofrequency balloon angioplasty. Group B: The iliac segments of rabbits, which had been manually separated in to intime- media and media-adventitia layes, were performed in radiofrequency balloon angioplasty. Radiofrequency dose delivered from a metal electrode balloon produced dose-dependent thermal energy with compression. It produces fusion of separated wall layers. Range of radio -frequency from clean and shallow craters with histologic evidence of thermal compression at does(

To fully incarnate"specialization"peculiarities of microbiology teaching courses by means of optimizing microbiology teaching contents and curriculum systems,and making up a new syllabus suitable to different specialties will lay a very solid foundation for cultivating medical talents with specialty traits.

Objective To observe the effects of lentivirus-mediated RNA interference silencing IL-1 type Ⅰ receptor on the expression of mitogen-activated protein kinase (MAPK) in a rat model of osteoarthritis (OA), and to explore the role of IL-1 and MAPK in OA. Methods Forty SD rats were randomly divided into four groups(A-D, each group: n = 10). The rats (A-C group) were underwent unilateral anterior cruciate ligament transaction and partial excision of the medial meniscus. At day 7 and 9 after operation, the rats of group A were respectively received 40 μL of lentivirus-mediated RNAi silencing IL-1 type Ⅰ receptor by intra-articular injection, while the rats of group B were received lentivirus-mediated RNAi non-silencing IL-1 type Ⅰ receptor, and the rats of group C were received saline. The rats of group D were taken for normal control. All rats were sacrificed four weeks after the surgery. The knees were harvested to observe macropathologic changes of the joint cartilage. ERK1/2, JNK1/2 and p38 proteins in the cartilage were detected by Western blot. Results Cartilage degradation in group A was milder than that in group B and C (P<0.05),but was worse compared to group D (P<0.05). Level of p38 expression in cartilage in group A was lower than that in group B and C (P<0. 05), but had no significant difference compared to group D (P>0.05). Levels of ERK1/2 and JNK1/2 expressions in cartilage in group A were lower than that in group B and C(P<0.05),but was significantly increased compared to group D(P<0.05). Conclusions Lentivirus-mediated RNAi silencing IL-1 type Ⅰ receptor can inhibit the expression of MAPK, in particular,p38 protein was strongly inhibited.

Pathogen biology is a main course of curricula in medical university.In developing quality courses,we optimized Pathogen biology course content,created the PBL teaching mode suitable for this course,set up network teaching platform,enhanced teachers' qualification,constructed comprehensive and exploratory experiment teaching system,wrote new teaching syllabus and other measures,made the Pathogen biology course construction more reasonable and perfect.

Objective To explore the role of serotonin(5-HT) in obsessive compulsive disorder(OCD) and the difference in platelet 5-HT content between OCD and healthy controls, the obsession and the compulsion subgroup. Methods The concentration of serotonin (5-HT) in twenty-seven patients with OCD and twenty-seven patients without OCD were detected in the study. Results Platelet serotonin level in patients with OCD ( ( 139 ±172 ) μg/L) was lower than that in patients without OCD ( ( 248 ± 215 ) μg/L), and the differences were significant (P＜0.05). Conclusion The present results support the hypothesis that 5-HT hypofunctionality contribute to OCD. And the differences between the obsession and the compulsion subgroup in the role of 5-HT are significant.

Aim To investigate the effects of new derivatives of 1H-isoindole-1,3(2H)-dione on angiogenesis in chick chorioallantoic membranes(CAM). Methods The blood vessels of CAM were calculated to determine the antiangiogenic effects of different new compounds. Results Among the 18 new derivatives of 1H-isoindole-1,3(2H)-dione , compound 1,2,3,4,11 and 13 showed significant inhibition on angiogenesis of CAM.Conculsion The 6 new derivatives of 1H-isoindole-1,3(2H)-dione screened out in this experiment may be novel angiogenesis inhibitors.

Objective; To clone, sequence and analyze the coding sequences of the Mr 15000 and Mr 9000 active segments of natural granulysin derived from human CTLs activated by allogenic antigen ,in order to establish the basis for further purifying and investigating the immune - impairing mechanism of granulysin. Methods; The coding sequences of the Mr 15000 and Mr 9000 granulysin gene were amplified from the total RNA of activated CTLs of healthy person after reverse transcription by Nested - PCR, inserted into pET32a ( + ) vectors and then transformed into E. Coli TOP10, respectively. The recons were identified by PCR, endonuclease digestion and sequencing. Results: The whole coding sequences of the Mr 15000 and Mr 9000 active segments were successfully cloned as expected. The accurate pET32a - Mr 15000 and pET32a - Mr 9000 recons were obtained through Colony - PCR, endonuclease digestion and sequencing. There lied polymorphism on the 119 th amino acid of the product encoded by GLS gene. Conclusion; The coding sequences of the Mr 15000 and Mr 9000 active segments of human granulysin can be obtained and cloned by the methods mentioned above and can be used for subsequent research.
