Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

Since 1970's , lots of studies on biodegradation of chloroanilines (CAS) have been done, especially, in these aspects: spieces and capability of the microbes; metabolic pathway; gene cloning, expression of degradation plas-mid and pivotal metabolic emzymes. It is necessary for us to review the study on biodegradation of chloroanilines in order to summarize some useful results and the problems in this study.

Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.

Thrombotic diseases in different forms become a great threat to human health. Such anti-platelet aggregation drugs as aspirin and clopidogrel are common drugs in clinic. However, along with the appearance of resistance and side effects of western anti-platelet aggregation drugs, anti-platelet aggregation traditional Chinese medicines promoting blood circulation to remove blood stasis have gradually become an important study orientation. Platelet is one of major participant in thrombosis, and plays an important role as a bioactive material in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, mainly involving two aspects--the evaluation for the anti-platelet aggregation activity of traditional Chinese medicines and the screening of their active components. This paper summarized the applications of platelets in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, so as to provide basis for further studies.

Taking application of some isolation and purification technologies, such as solvent extraction, preliminary solvent isolation, column chromatographies over silica gel and Sephadex LH-20 gel and preparative HPLC, 10 compounds were obtained from Gynura nepalensis cultivated in the suburban area of Beijing. Their structures were identified by spectroscopic methods and comparison with literature as (3R) -3-hydroxy-β-ionone (1), (3S,5R, 6S, 7E) -5, 6-epoxy-3-hydroxy-7-megastigmen-9-one (2), (+) -boscialin (3), 3, 6-trans-3-hydroxy-α-ionone (4), 3, 6-cis-3-hydroxy-α-ionone (5), 3, 4-cis-3, 4-dihydroxy-β-ionone (6), ethyl caffeate (7), loliolide (8), 1H-indole-3-carbaldehyde (9), and 3-(hydroxyacetyl)indole (10), respectively. All compounds were isolated from the title plant for the first time, and with compounds 1, 2, 4-7, 9 and 10 being isolated from Gynura species for the first time. Structurally, the above compounds 1-6 belong to C13 nor-sesquiterpenoids, sharing the same carbon skeleton of megastigmane. According to this study, they are one of major kinds of chemical constituents of Gynura nepalensis and have important reference value for the investigation on phytotaxonomy of this species.

Objective To study the antigenicity of human thyrotropin receptor(hTSHR)amino terminus (amino acid 29～280)and its association with Graves' disease.Methods Total thyroid RNA was prepared from human normal thyroid tissue.RNA was then reversely transcripted and cDNA was subjected to PCR amplification.PCR product was cloned into pcDNA3.1 and the recombinant plasmid was named pcDNA3.1/hTSHR188～940bp. Balb/c mice were immunized with peDNA3.1/hTSHR188～940bp. The levels of serum thyroxin,anti-TSHR antibody(TRAb)and thyroid stimulating antibody(TSAb)were measured,and the pathological changes of thyroid tissue were also observed.Results A 753 bp fragment encoding hTSHR ectodomain amino end was obtained after PCR amplification.Confirmed by Hind Ⅲ restriction enzyme digestion and DNA sequencing,pcDNA3.1/hTSHR188～940bphad been constructed successfully,with the correct sequence and direction of hTSHR188～940bp.In the Balb/c mice treated with pcDNA3.1/hTSHR188～940bp,elevated TRAb in week 6(0.148±0.018)were observed compared with those at week o(0.106±0.006,P＜0.01),and kept a higher level till week 10(0.134±0.011,P＜0.01).T4 and TSAb index values were significantly increased in week 10.Serum T4 concentration increased from(41.02±7.97)μg/L in week 0 to(62.20±12.77)μg/L in week 10(P＜0.01);TSAb index values rose from 0.864±0.076 at week 0 to 1.392±0.615(P＜0.01).Thyroid pathological examination showed that proliferated thyroid follicular epithelial cells and foll icular eapacity increased.Inflammatory cells were occasionally found.Conclusions There are antigen epitopes in hTSHR ectodomain amino acid 29～280,which can stimulate the production of TSAb.And the latter induces hyperthyroidism and Graves' disease like manifestations.It suggests that hTSHR ectodomain amino acid 29～280 is closely associated with Graves' disease,and maybe one of important etiological factors leading to the disease.
