Objective To research the reversal effects of psoralen on multidrug resistant action and its influence on intracellular Ca2+ concentration in MCF-7/ADR cells and to explore its possible mechanisms of reversing multidrug resistance (MDR). Methods The inhibitory effects of psoralen on the viability of MCF-7/ADR cells were determined with MTT assay, intracellular adriamycin (ADR) concentration was assayed with HPLC and the intracellular Ca2+ concentrations in different incubative duration were detected with confocal microscope. Results Psoralen from 1 to 20 μmol/L reduced the value of IC50 of ADR in MCF-7/ADR cells, enhanced accumulation of ADR and influenced Ca2+ concentration with a negative correlation in different duration (24 h, 48 h and 96 h). Conclusion Psoralen can reverse MDR in MCF-7/ADR cells and its mechanism may be related to the increase of the intracellular accumulation of ADR by enhancing the intracellular Ca2+ concentration.

Autosomal dominant polycystic kidney disease (ADPKD) is a most common inherited renal disease, about 50% with a family history, although the exact etiology not yet clear. To date, ADPKD, a multisystem disorder without effective preventive and therapeutic means, has been shown to be detrimental to human health. Recent studies show that severe oligoasthenozoospermia, necrospermia, immotile sperm, azoospermia, epididymal cyst, seminal vesicle cyst, and ejaculatory duct cyst found in male ADPKD patients may lead to male infertility, though the specific mechanisms remain unknown. Structural anomaly of spermatozoa, defect of polycystin, mutation of PKD genes, and micro-deletion of the AZF gene could be the reasons for the higher incidence of abnormal semen quality in male ADPKD patients. Assisted reproductive techniques can increase the chances of pregnancy, whereas the health of the offspring should be taken into consideration. This article presents an overview of reproductive issues concerning infertile male ADPKD patients from the perspective of the morbidity, pathophysiological mechanism, diagnosis, and management of the disease.

AIM:To study the rationality and the best dosage of Qidan Decoction (Radix Astragali,Radix et Rhizoma Salviae miltiorrhizae,Fructus Psoraleae,etc.) on inhibiting gastric cancer metastasis. METHODS:The ability of inhibiting gastric cancer metastasis and the activity of NK cell were detected as indexes to appraise the rational and the best dosage. RESULTS:The function of Astragalus membranaceus,Salvia miltiorrhiza.Ege.,psoralea corylifolia and Lycium Barbarum on inhibiting gastric cancer metastasis and rising the activity of NK cell was significant(P

AIM:To investigate the mechanism of Maxing Shigan Decoction(Herba ephedrae,Semen armeniacae amarum,Radix er Rhizoma glycyrrhizae,Gypsum fibrosum) against type Ⅰ hypersenstivity reaction. METHODS: The experiment of passive cutaneous anaphylaxis(PCA) was used to determine the effect of Maxing Shigan Decoction on degranulation of mast cells in vivo.For in vitro study,the drug serum of Maxing Shigan Decoction was added to the culture medium of sensitized RBL-2H3 cells.The antigen-induced release of degranulation was measured by enzymatic assay,histamine by enzyme immunoassay(EIA) and cytokines by enzyme-linked immunosorbent assay(ELISA). RESULTS: The results showed that treatment with drug serum of Maxing Shigan Decoction was followed by a decrease in PCA of rats and in degranulation,histamine,TNF-? and IL-4 from RBL-2H3 cells induced by antigen. CONCLUSION: Maxing Shigan Decoction may suppress the type Ⅰ hypersensitivity reaction by inhibiting the action of mast cells.

Objective To detect genetic mutation of apolipoprotein B-100(apoB-100)in patients with primary hypercholesterolemia.Methods One special segment of apoB-100 gene from nucleotide 10549 to 10895 was amplified by polymerase chain reaction(PCR).The PCR products were denatured and hybridized with specific aligonucleotide labeled with digoxigenin,and were analyzed by single strand conformation polymorphism(SSCP)to detect the apoB-100 gene mutation 3531CGC→CGT or other mutations.Results Overall 41 members of 11 primary hypercholesterolemia families were detected,but the above genetic mutation was not detected.Conclusion This genetic mutation is unlikely to exist or of significantly low incidence in Chinese population,and might not be the main cause of primary hypercholesterolemia in the 11 primary hypercholesterolemia families.

Aim To investigate the mechanism of achyranthes bidentata polysaccharides on degranulation of mast cells. Methods The experiment of passive cutaneous anaphylaxis was used to determine the effect of achyranthes bidentata polysaccharides on degranulation of mast cells in vivo. For in vitro study, various doses of achyranthes bidentata polysaccharides were added to the culture medium of sensitized RBL-2H3 cells. The antigen-induced release of degranulation was measured by enzymatic assay, histamine by EIA and cytokines by ELISA. In addition, the activation of Akt and p38 were measured by Western blot. Results Treatment with achyranthes bidentata polysaccharides was followed by a decrease in PCA of rats and ?-hexosaminidase, histamine, TNF-?,IL-4,Akt and p38 of RBL-2H3 cells induced by antigen. Conclusions Achyranthes bidentata polysaccharides might suppress the anaphylactic reaction through inhibition of action of mast cells. Akt and p38 contributed at least in part to this event.

AIM: The effects of YIGU capsule on proliferation and IGF-I mRNA protein expressions in osteoblasts were studied. METHODS: (1) Forty 12-month old Sprague-Dawley female rats were divided randomly into four groups (YIGU capsule high dose group, medium dose group and low dose group; saline group), the drug-containing serum and control serum were prepared. (2) The new-born Sprague-Dawley rat osteoblasts were cultured with different YIGU capsule drug-containing serum at different concentrations and different exposure time. MTT method was used to observe proliferation of osteoblasts. (3) RT-PCR method was used to measure the relative IGF-I mRNA levels and ELISA method was used to measure IGF-I secretion at different exposure time. (4) ELISA method was used to measure IGF-I secretion at different exposure time. RESULTS: (1) Proliferation of osteoblasts was more than the control groups after 48, 72 and 96 h, respectively (P
