Objective: To observe the effects of electroacupuncture (EA) on uterine prostaglandin F2α (PGF2α), cyclooxygenase 2 (COX-2) and nuclear factor κB (NF-κB) in rats with primary dysmenorrhea (PD) and to discuss the possible mechanism in EA intervening PD. Methods: Forty Sprague-Dawley female rats were randomly divided into a blank group, a model group, an EA group and an ibuprofen group, with 10 rats in each group. The PD model was established using estradiol benzoate combined with oxytocin in the model group, EA group and ibuprofen group. At the same time of modeling, rats in the EA group were given EA at Guanyuan (CV 4) and Sanyinjiao (SP 6) once a day for 20 min each time for 10 consecutive days. Ibuprofen was intragastrically administered once a day for 10 consecutive days in the ibuprofen group. The same amount of normal saline was intragastrically administered once a day for 10 consecutive days in the blank group and model group. The number of writhing of rats in each group within 30 min was compared on the 11th day just after the interventions. The uterine homogenate supernatant was separated and the PGF2α level was detected by enzyme-linked immunosorbent assay. Western blot was applied for the detection of the expression levels of COX-2, phospho-NF-κB p65 and NF-κB p65 proteins in uterine tissues. Results: Compared with the blank group, the number of writhing in the model group increased significantly (P<0.01), and the expression levels of PGF2α, COX-2, phospho-NF-κB p65 and NF-κB p65 proteins in uterine tissues were significantly increased (all P<0.01). Compared with the model group, the number of writhing in the EA group and ibuprofen group were significantly reduced (both P<0.01), and the expression levels of PGF2α and COX-2 protein in uterine tissues were significantly reduced (both P<0.01). Compared with the model group, the phospho-NF-κB p65 level in uterine tissues in the EA group was significantly reduced (P<0.01). Compared with the ibuprofen group, the phospho-NF-κB p65 level in the EA group was significantly reduced (P<0.01). Conclusion: The mechanism of EA for PD rats may be related to inhibiting the phosphorylation of NF-κB and reducing the levels of COX-2 and PGF2α in uterine tissues.

Objective Compare and analyze the characteristics of the coronary angiography between Han nationality and Uygur nationality in Xinjiang autonomous region Methods 2?200 clinical data and angiographic data from 1991 to 1999 were reviewed There were divided into two groups according to different nationality The extent of the lesions and the proximal calibres of coronary artery were measured and compared Results The proximal calibres of coronary arteries of Uygurs are greater than those of Hans The lesions of Uygurs′ coronary heart disease (CHD) patients are more severe than Hans′: more three branch lesion, more C type lesion and total occlusion cases. There are statistical differences between two nationalities Conclusion Proximal calibres of coronary branches of Uygures are bigger than Hans, but Uygur patients suffer more severe lesions of coronary arteries as compared with Hans

Perchlorate is a new emerging environmental pollutant that is very stable and persistent,and it can diffuse rapidly in the environment. The environmental problems caused by perchlorate have attracted a great attention from many environmental scientists. However,up to now,a few reports on perchlorate pollution have been reported in China. In this paper,for perchlorate as an environmental pollutant,the sources,characteristics,detecting methods and toxicological effect on human body were reviewed,and the further research topics were presented.

Objective To observe the effect of Buzhong Yiqi Decoction medicated serum on PI3K、AKT、survivin in lung adenocarcinoma A549/DDP cells,and explore its functional mechanism.Methods Buzhong Yiqi Decoction medicated serum of middle dosage (0.576 g/mL)were prepared,and A549/DDP cells were divided into four groups:blank serum group,the best containing medicine serum group and LY294002 group (blockers group), the best containing medicine serum +LY294002 group (combination group).The protein expression of PI3K,AKT and Survivin were detected by Immunocytochemistry and Western blot.Results Compare with blank serum group,the protein expression of PI3K、AKT and Survivin in best containing medicine serum and combination group were significantly lower(P<0.05 ),and the later was more lower,but there was no significant differences between best containing medicine serum and combination group.The expression of survivin in LY294002 group were significantly lower than blank serum group(P<0.05 ).Conclusion Buzhong Yiqi Decoction can reduce the protein expression of PI3K,AKT and surviving,increase the sensitivity of A549/DDP to DDP through PI3K/AKT signal transduction pathway.

AimTo investigate the immune effects of the genetic engineering vaccine against swine cysticercosis with the animal mode of kunming mouse. Method78 kunming mice were randomly divided into three groups: 1 )injection one times with the vaccine, 2)injection twice with the vaccine at intervals of ten days, 3)non-vaccination group. All the mice were infected with the vial hatched oncopheres by the tag vein at 20 days after the first vaccination,and were killed and dissected to look for swine cysticerci 63 days later. In order to know the immune response of the vaccine and the stateof parasites in the rats,the antigens and antibodies of swine cysticerci were detected by immune methods. ResultsThe vaccine was safety to all the vaccinated rats. The antibodies against swine cysticerci began to appear positive in some of the immunized mice at 7 days postvaccination,and they were all positive at 21 days. 65 cysticerci were found in the mice of the nonvaccination group,which lodged mainly in the chests. 2 and lcysticerci were respectively found in two rats of the first group and in one rat of the second group, their protective rates of cysticerci were 96.9％ and 98. 4％,respectively. ConclusionKunming mouse as the animal model of swine cysticercosis was stable and reliable,and the genetic engineering vaccine against swine cysticercosis was safety and efficiency.
