Objective To study the effects of p,p’-DDE on intracellular calcium in the Sertoli cells of rats in vitro. Methods The primary culture of the Sertoli cells separated from the testicle tissues of rats was conducted, and the cells were treated with p,p’-DDE at the doses of 10, 30 and 50 ?mol/L. Fura-2/AM was used as the probe to examine the changes of intracellular calcium by two-wavelength calcium fluorescence system. Results Compared with the control, in 50 ?mol/L group of p,p’-DDE, the intracellular calcium level significantly increased. Conclusion p,p’-DDE may disrupt intracellular calcium homeostasis which will induce calcium overload in Sertoli cells in the testicle tissues of SD rats.

Objective To study the relation between vascular endothelial growth factor(VEGF) and the degree of coronary artery stenosis as well as the formation of collateral circulation in patients with acute myocardial infarction (AMI). Methods Seventy-six cases of AMI had undertaken selective coronary angiography on the third to seventh day after admission and also at six months afterwards in order to define the degree of coronary artery stenosis and the presence of collateral circulation. A blood sample of 5 mL was taken in each patient before the first coronary angiography to test for the level of VEGF by enzyme linked immunosorbend assay. Results The level of VEGF in patients with coronary artery stenosis less than 50%, 50%~75% and greater than 75% were (97.6?17.3) ng/L, (241.6?28.9) ng/L and (391.7?48.4) ng/L respectively (P

Objective To explore the effects of AP on pulmonary fibrosis. Methods Alveolar macrophages (AM) were treated by AP for 24 hours. Pulmonary fibroblasts (FB) were cultured with the supernatant of AM medium. The protein of transforming growth factor beta 1 (TGF-?1) of AM, the proliferative activity and hydroxyproline (Hyp) content of FB were examined. Rats were treated with AP by intratracheal instillation and sacrificed at 3 days. The TGF-?1 mRNA content in the lung was examined. Results The positive staining macrophages in low and high AP groups and the quantity of TGF-?1 in high AP group were obviously higher than those in the control group (P

Objective To evaluate the safety of new-generation of antidepressants and amitriptyline in the treatment of depression in patients with coronary heart disease (CHD). Methods A total of 194 patients with first-episode depression with CHD were divided into amitriptyline group(n=40), venlafaxine group(n=40), mirtazapine group(n=48)and escitalo?pram group(n=66). The blood routine test, liver function, blood lipids and blood glucose (GLU) were monitored after treat?ment for six weeks, and which were compared before and after treatment. Results The levels of white blood cells (WBC) and neutrophil count (NE) were significantly lower in amitriptyline group after 6-week treatment (P<0.05), but the levels of acid alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (T-CHO) and GLU were significant?ly increased after treatment than those before treatment (P<0.05). The levels of WBC, NE and GLU were significantly de?creased in venlafaxine group after 6-week treatment (P<0.05). The levels of ALT, AST, low density lipoprotein (LDL) were significantly increased in mirtazapine group after six-week treatment (P<0.05). In escitalopram group, the level of three ac?yl glycerin (TG) was significantly increased after six-week treatment than before treatment ( P<0.05). There was a signifi?cant difference in AST change after treatment between venlafaxine group and mirtazapine group (P<0.05). There was a sig?nificant decrease in WBC in amitriptyline group than that of mirtazapine group after six-week treatment ( P<0.05). There was a significant decrease in NE in amitriptyline group than that of mirtazapine group and escitalopram group ( P<0.05). The increase level of AST was significant higher in amitriptyline group than that of venlafaxine group (P < 0.05). Conclusion Three different kinds of new-generation of antidepressants have fewer influence in routine blood test, liver function, blood lipids and blood glucose than those of amitriptyline in the treatment of depression in patients with CHD.

Objective To investigate the effect and mechanism of liver X receptor ( LXR ) agonist on expression of fatty acid synthase( FAS) in diabetic kidney. Methods In the part of in vivo study, immunostaining was used to detect the FAS protein expression in kidney. 16-week-old male db/db mice on C57BL/6 background were administered via gavage a LXR synthetic agonist, TO901317, at a dose of 3 mg · kg-1 · d-1 or vehicle ( 0. 5%Carboxymethyl Cellulose Sodium, CMC-Na) alone for 7 d;Quantitative RT-PCR and Western blot were used to detect mRNA and protein levels of FAS and SREBP-1. In the part of in vitro study, MCT cell(a mouse murine proximal tubule cell line)was treated with 10μmol/L TO901317 for 24 h or transfected with active SREBP-1c expression vector (SREBP-1cN). HEK293 cells(a human renal tubule cell line)were transfected with mFAS-(1. 7 kb)-luc, LXR expression vector or SREBP-1cN for 12 h. Quantitative RT-PCR and luciferase reproter assay were utilized to examine FAS mRNA level and FAS promoter activity. Results FAS was abundantly expressed in renal cortex, with low expresson in renal glomeruli. The mRNA and protein expressious of FAS in kidney of db/db mice were lowered compared with db/m mice. TO90137 treatment increased FAS mRNA expression by 1. 3-fold. TO901317 increased expression of SREBP-1 in kidneys of db/m and db/db mice by 5. 1-fold and 17-fold, respectively. TO901317 and overexpression of SREBP-1c increased expression of FAS in MCT cells by 1. 5-fold and 1. 8-fold. Transcription activity of FAS were induced by TO901317, LXR, and SREBP-1cN overexpressions in HEK293 cells. Conclusions Both direct(LXRE)and indirect(SREBP-1c)mechanisms may contribute to the up-regulation of FAS expression by LXR in renal proximal tubule cells.

OBJECTIVETo compare the difference in depression relief in the treatment of depressive disorder at the acute stage between the combined therapy of acupuncture and 5-HT (5-hydroxytryptamine) selective serotonini reuptake inhibitors (SSRIs) and the single application of SSRIs and explore the impact on the imbalance of 5-HT and TH1/TH2.

METHODSNinety cases of depressive disorder at the acute stage were randomized into a combined therapy group and a medication group, 45 cases in each one. In the medication group, SSRIs were prescribed forl oral administration, once or twice a day, continuously for 4 weeks. In the combined therapy group, on the basis of treatment as the medication group, acupuncture was combined. The main acupoints were Baihui (GV 20), Yintang (GV 29), Shenting (GV 24), Fengchi (GB 20), Dazhui (GV 14) and Sishencong (EX-HN 1), once every two. days, continuously for 4 weeks. Before treatment, and after the 1st, 2nd and 4th weeks of treatment, the Hamilton depression scale (HAMD) was used to evaluate the depression severity. Separately, before and after the 4 weeks of treatment, the levels of serum 5-HT, interleukin-1 beta (IL-1β), interleukin-6 (IL-6), interleukin-4 (IL-4) and interleukin-10 (IL-10) were determined and compared with those in 45 cases of the healthy group.

RESULTSHAMD score was reduced in the 1st, 2nd and 4th weeks of treatment as compared with that before treatment in the combined therapy group (all P<0 01). HAMD score was reduced in the 2nd and 4th weeks of treatment as compared with that before treatment in the medication group (all P<0. 01). HAMD scores in the combined therapy group were lower than those in the medication group in the 1st, 2nd and 4th weeks of treatment (all P< 0. 01). Before treatment, in the combined therapy group and the medication group, the levels of serum 5-HT, IL-4 and IL-10 were all lower than those in the healthy group (all P<0. 01); the levels of IL-1β and IL-6 were higher than those in the healthy group (all P<0. 01). In the combined therapy group and the medication group, the levels of 5-HT, IL-4 and IL-10 in 4 weeks of treatment were all increased as compared with those before treatment (all P<0. 01), and the levels of IL-1β and IL-6 were lower than those before treatment (all P<0. 01). In the combined therapy group, the levels of IL-1β and IL-6 in 4 weeks of treatment were lower than those in the medication group, and the levels of 5-HT, IL-4 and IL-10 were higher than those in the medication group (P<0. 01, P< 0. 05).

CONCLUSIONThe combined therapy of acupuncture and SSRIs achieves much quicker and more effective re-' sult for relieving depression in the patients of depressive disorder as compared with simple oral administration of' SSRIs, and much more contributes to adjust the imbalance of serum 5-HT and TH1/TH2.
