Objective:To study the effect of invigorating the kidney and spleen complex prescription on deltamethrin intoxicated pregnant rats. Methods:Pregnant rats were divided into 5 groups. Except the blank group,other groups were orally fed 1/20LD50(6.93mg/kg)DM daily from day 1 to 15 when proved pregrancy. 4 Hours later,rats in model group were given physiological saline,other 3 groups were given high/ median /low dose of Zhuyun Formula. Half pregnant rats were killed on D15. The rest was kept until labour. The abortion rate,survival rate,delivery condition,the level of estradiol,progestogen were observed. Results:With respect to abortion rate,model group showed statistical signifi cance when compared with other groups. Model group also showed low progesterone level. With the treatment Zhuyun Ⅲ,it had desirable effect in decreasing abortion rate,and increasing the level of progesterone. The labour time of all groups was within the normal range. Conclusion:DM had toxicity on reproduction,it could lead to abortion which was related to endocrine function of pregnant rats. Zhuyun Ⅲ could regulate the above condition and relief DM toxicity.

Objective To observe the impacts of Kechuanning on expression of signal transducer and activator of transcription 6 (STAT 6) in CD4+, CD8+T lymphocytes of athma rats induced by virus, and analyze the mechanism of Kechuanning in treating asthma induced by RSV. Methods The PBMC was isolated from the peripheral blood, CD4+T, CD8+T lymphocyte was separated by immunomagnetic beads. The purity and activity of CD4+T and CD8+T lymphocytes were measured by using flow cytometry, trypan-blue dye exclusion test. The protein expression of STAT6 was detected by fluorescence-activated cell sorting. Results The descending progress of the trial were supported by the purity and activity of CD4+T, CD8+T lymphocyte. CD4+T lymphocyte in the asthma model group were increased (P<0.01), however the increase of CD8+T lymphocyte were not significant (P>0.05). The expression of the protein of STAT6 in the treated group with Kechuanning decoction were decreased than that in the model group (P<0.01). Compared with Dexamethasone and Salbutamol group, there were no significant differences (P>0.05). Conclusion Kechuanning decoction could decrease the protein of STAT6 in CD4+, CD8+T lymphocyte, thereby it could regulate the disorder of Th1/Th2, thus prevent and treat the asthmatic attack induced by virus.

Objective To investigate the influencing factors of the results of liver function tests.Methods The clinical data of 357 cases of outpatient examination for liver function were retrospectively analyzed.According to the results of the examination,they were divided into two groups,178 cases in the control group (normal liver func-tion);179 cases in observation group (abnormal liver function).The influencing factors of liver function test results were analyzed.Results In the observation group,the gender,marital status,age,culture degree,BMI,sleep time com-pared with the control group,the differences in marital status were statistically significant(all P <0.05),the liver function abnormal rate of male was 58.66%,which was higher than 41.34% of female(χ2 =14.139,P <0.05).The detection rate of abnormal liver function of the people with age over 40 years old was 55.87%,which was higher than 44.13% of the people with age under 40 years old (χ2 =8.495,P <0.05).The detection rate of abnormal liver func-tion of the crowd in high school level and above was 45.25%,which was lower than 54.75% of the crowd under the high school(χ2 =5.685,P <0.05).The detection rate of abnormal liver function of the crowd with BMI≥24kg/m2 was 62.57%,which was higher than 37.43% of the crowd with BMI <24kg/m2 (χ2 =5.731,P <0.05).The detec-tion rate of abnormal liver function of the crowd with sleep time≥8h was 53.07%,which was lower than 46.93% of the crowd with sleep time <8h (χ2 =18.011,P <0.05).There was no significant difference in the detection rate of abnormal liver function of marriage between the two group(P >0.05).Conclusion The gender,age,culture degree, BMI,sleep time have impact on the liver function test,and the bad eating and living habits should be reasonable corrected,the physical exercise should be strengthened,and the quality of life should be constantly improved.

OBJECTIVETo explore the relationship between the genetic variants of the norepinephrine transporter gene solute carrier family 6 member 2 (SLC6A2) and blood stasis pattern (BSP) in patients with essential hypertension (EH).

METHODSDNA was extracted from the peripheral blood of 830 EH patients (532 were typed as BSP and 298 as non-BSS) and 512 persons with normal blood pressure (for control), to detect the polymorphisms of SLC6A2 promoter-3 and 2 by PCR-RFLP, and estimate the haplotype frequency adopting SHEsis program.

RESULTSChi2 partition showed that frequency of promoter-2-GG genotype in EH patients of BSP was lower than that in the EH patients of non-BSP and the normal control (P = 0.001); while that of promoter-3-GG/GA in the EH patients with severe BSP was the highest (P < 0.001). Logistic regression analysis showed that after the miscellaneous factors being rectified, with the reference category of EH-non-BSP, the relative odds ratio (OR) of promoter-2-GC/CC genotype for EH-BSP was 1.535 (95% CI: 1.094-2.155, P = 0.013); that of promoter-3-AG/GG genotype for EH with severe BSP was 1.925 (95% CI: 1.199-3.091, P = 0.007); while OR of G-C haplotype (promoter-3-promoter-2) for EH-BSP was 2.127 (95% CI: 1.202-3.765, P = 0.010), showing the strongest intensity.

CONCLUSIONSLC6A2 promoter-3-GA/GG genotype may be a susceptibility gene for patients of EH with severe BSP; promoter-2-GC/CC and G-C haplotype might be the susceptible factors to EH-BSP.
