The clinical therapeutic efficacy and hematologic parameters in patie nts were observed, and systemic gene analysis was conducted with PAGE, PCR, PCR SSCP, RT PCR and DNA sequences analysis and mRNA detection, in order to s tudy the molecular mechanism from the relationships between genetic mutation and clinical efficacy, gene expression and its regulation. Results: YSSXL showed obvious therapeutic effect in treating β thalassemia. Gene analysis revealed that it did not change the genetic mutatio n type, but could obviously increase hemoglobin, fetal hemoglobin (HbF), γ/(β+ γ) globin ratio, γ globin mRNA expression and GM CSF mRNA expression in patients, as well as the GM CSFmRMA in marrow of mice after 60 Co radia tion. Conclusion: YSSXL has a remarkable therapeutic effect on β tha lassemia, and its possible mechanism is its action in unlocking γ gene, in creasing the γ globin expression and enhancing HbF synthesis so as to compe nsate for the gene defect. This study has opened a new path for the treatment of β thalassemia with TCM.展开更多

By selecting the Shen-Dong coal mining subsidence area as the research field, this paper studies the changes in precipitation infiltration recharge in the circumstances of coal mining subsidence by means of field geological investigation and laboratory simulation experiments, which is expected to provide a scientific basis for eco-environmental restoration in the mining area. The results indicate that at the unstable stage of subsidence, three types of subsidence in the Shen-Dong mining area have positive effects on the precipitation infiltration recharge, and the type of full-thickness bedrock subsidence has the greatest influence. In the stable stage of subsidence, the precipitation infiltration process after long- term drought and the moisture migration in the aeration zone undergo three different stages: evaporation-infiltration before precipitation, infiltration-upward infiltration-infiltration during precipitation and evaporation-infiltration after precipitation. During a heavy rainfall infiltration process, the wetting front movement in fine sand, coarse sand and dualistic structure of fine-coarse sand consists of two stages: the stage of wetting front movement during precipitation, in which the wetting front movement distance has linear relationship with the depth, and the stage of wetting front movement after precipitation, in which the wetting front movement distance has the power function relationship with the depth. The wetting front movement velocity is influenced by the rainfall amount and the lithology in the aeration zone. However, as the depth increases, the movement velocity will decay exponentially.展开更多

The COH implantation dysfunction model in mice was established by intraperitoneal injection of 7.5 IU pregnant mare’s serum gonadotrophin(PMSG), followed by 7.5 IU human chorionic gonadotrophin(HCG) 48 h later. Then the female mice were mated with male at a ratio of 2:1 in the same cage at 6:00 p.m. The female mice from normal group were injected intraperitoneally with normal saline and mated at the corresponding time. Day 1 of pregnancy was recorded by examining its vaginal smears at 8:00 a.m. of the next day. Fifty successfully pregnant mice were equally randomly divided into 5 groups: normal control pregnant group(NC), COH implantation dysfunction model group(COH), low dosage of Bu-Shen-An-Tai recipe group(LOW), middle dosage of Bu-Shen-An-Tai recipe group(MID) and high dosage of Bu-Shen-An-Tai recipe group(HIGH). Then from day 1, the mice in different groups were respectively intragastrically given corresponding treatments at 9:00 a.m. for 5 consecutive days. The concentrations of 17β-estradiol(E) and progesterone(P) were determined by radioimmunoassay(RIA). The ultrastructural changes of ovarian tissues were observed by transmission electron microscope(TEM). The histopathological changes of ovarian tissues were observed by HE staining. The number of atretic follicles and pregnant corpus luteum were also recorded. TUNEL was applied to measure apoptotic cells of ovarian tissues. Western blotting was used to detect the protein expression of apoptosis-related factors like Bax, Bcl-2 and cleaved-caspase-3 in ovarian tissue of mice. The results showed that ovarian weight, the concentrations of Eand P, the number of atretic follicles and pregnant corpus luteum, as well as the apoptosis of granulosa cells were significantly increased in the COH group. The ultrastructures of ovarian tissues in the COH group showed that chromatin in granulosa cells was increased, agglutinated, aggregated or crescent-shaped. The focal cavitation and the typical apoptotic bodies could be seen in granulosa cells in the late stage of apoptosis. After the treatment with different doses of Bu-Shen-An-Tai recipe, the ultrastructural changes of ovarian granulosa cells apoptosis were dramatically improved and even disappeared under TEM. Visible mitochondria and mitochondrial cristae were increased and vacuoles were significantly reduced. The lipid dropltes were shown in a circluar or oval shape. The protein expression levels of Bax and cleaved-caspase-3 were decreased, and the expression of Bcl-2 protein was increased after treatment. It was concluded that Bu-Shen-An-Tai recipe can inhibit the apoptosis of ovarian granulosa cells, probably by up-regulating the protein expression of Bcl-2 and down-regulating Bax and cleaved-caspase-3, which contributes to the formation and maintenance of ovarian corpus luteum. It’s helpful to promote the embryonic implantation, to reduce embryo loss and ultimately to improve the success rate of pregnancy.展开更多

Methods: Sixty-one patients with CHD were divided into 3 groups according to their TCM Syndrome type, 10 patients in the group without Xin-Qi deficiency (Group A), 25 in the group with Xin-Qi deficiency but without Shen-Yang deficiency (Group B) and 26 in the group both with Xin-Qi deficiency and Shen-Yang deficiency (Group C). Levels of 17-hydroxy-corticoste-roid in urine (urinary 17-OHCS) per 24 hrs, and serum level of high density lipoprotein cholesterol (HDL-C) and high density lipoprotein phospholipid (HDL-PL) in them were determined in synchrostep and compared with those in the control group of 23 healthy aged persons, urinary 17-OHCS per 24 hrs was taken as the diagnostic standard to screen a new index for diagnosis of Shen-Yang deficiency Syndrome, and preliminary appraisal to the index was made. Results: Serum HDL-PL in the CHD-SYD patients( Group C) was 616+157 mg/L, which was obviously lower than that in the patients of Group A and B. With low HDL-PL(<650 mg/L) used as the index to diagnose CHD-SYD, the sensitivity was 73%, the specificity 86% and the accuracy 80%. Conclusion: HDL-PL <650 mg/L could be adopted as an index for CHD-SYD diagnosis, which is simple and practical.展开更多

Methods: Using consecutive intramuscular injection of hydrocortisone to build Shen-yang deficiency model rats, and detect their hemorheological and biochemical parameters. Results: Comparison between the model group and control group showed that the in vitro thrombus significantly lengthened in the model group (P<0.05), the dry weight increased (P<0.01), hematocrit and whole blood viscosity under high sheared change lowered (P<0.05), blood glucose elevated (P<0.01), and RBC infiltration index, aggregation index increased (P close to 0.05). Conclusion: Under the condition of Shen-yang deficiency, although blood does not show such properties of blood stasis as being 'viscous, concentrated, coagulated and aggregated', partial change of hemorheology occurs, and it is liable to form thrombus, which proves that the Shen deficiency status is accompanied with the tendency of blood stasis.展开更多

Group A,B,C and D were injected with bromocriptine [0. 3 mg/(kg · d)] during the pregnant day 6~ 8, respectively. Group B was given powder of Bu-shen herbs [3 g/(kg · d)]. Group C was injected with prolactin (8 IU) twice a day and Group D with progesterone [(8 mg/kg · d) in the pregnant day 1~ 11. The rats in Group E were normal pregnant rats. All these rats were killed at the pregnant day 12 to observe the expression of PrRP-R, PRL-R from the pituitary using RT-PCR. Results The pregnant rate and total number of litters in Group A were significantly lower than those in Group B, C, D and E (P<0. 01) and the expression of PrRP-R and PRL-R in the pituitary of Group A was higher than that of any other group. Conclusion Preparation Bu-shen plays a regulatory role in the secretion of prolactin possibly via modulating rats' hypothalamus and pituitary.展开更多
