Objective:To study the action of Xinnaotong on adhesion molecule expression by cultured endothelial cells and platelets. Methods: Tumor necrosis factor ?(TNF ?) stimulated ICAM I expression on the cell surface was studied with human umbilical vein endothelial cells(HUVEC).Thrombin stimulated expression of platelet P selectin was studied with human blood platelets. Adhesion molecule expression was measured by flow cytometry. Results: ICAM I molecule expression on HUVEC was significantly stimulated by TNF ?. The stimulatory effect of TNF ? on HUVEC was inhibited by Xinnaotong(0.25~2g/L) in a concentration dependent manner. The same dose of Xinnaotong can inhibit the p selectin expression on human blood platelets stimulated by thrombin. Conclusion: Xinnaotong inhibites expression of adhesion molecues(ICAM I, p selectin) in HUVEC and in human blood platelets.

Objective To investigate the ultrasound characteristics of prenatal fetus otocephaly . Methods Three prenatal fetus with otocephaly were examined with two -and three-dimensional ultrasoundand examined results were compared with the those of induced labor or autopsy ,and ultrasound characteristicsof prenatal fetus were analyzed and summarized .Results The ultrasound performance of three prenatal fetuswith otocephaly and the examination of the appearance after induced labor showed :(1) The most intuitiveinitial sonographic performance of otocephaly was manifested by the absence of stomach bubble andoverabundance of amniotic fluid.Among three fetus,one fetus had overabundance of amniotic fluid at the midstageof pregnancy,one fetus had normal amniotic fluid at the mid-stage of pregnancy and one fetus hadextremely high amount of amniotic fluid and absence of stomach bubble at late stage of pregnancy .(2) Allthree fetus showed agnathy and synotia (shifts of both ears to the midline) and microstomia deformity.(3) All three fetus had associated complications with deformity in other systems including two cases of patients withcleft lip and palat,both were the fracture unilateral cleft lip derived from small mouth .One fetus withdysmelia and one fetus with complicated cardiovascular deformity and situs inversus and .(4) The results ofexamination after induced labor or autopsy were consistent with those of the prenatal ultrasound examination . Conclusions Prenatal ultrasound examination is an effective and feasible means for the diagnoses ofotocephaly.When the symptoms of “absence of stomach bubble and extremely high amount of amniotic fluid ”occurred,the fetal ear and submaxilla should be examined to confirm stand -alone otocephaly prenatally.
4.Variation trend of male fertility and semen parameters.
National Journal of Andrology 2014;20(12):1059-1062
In recent years, the variation trend of male fertility and semen parameters has aroused much academic controversy and become a focus of public attention. For the assessment of male fertility, female pregnancy is regarded as a gold standard, but semen parameters are commonly used as surrogate or indirect evidence in clinical practice and laboratory research. The reference range of se- men parameters being used in China is based on the WHO recommended data and lacks the specific reference value for healthy Chinese men. No definite conclusion has yet been derived from studies at home and abroad on the general variation trend of semen parameters worldwide, but many researchers agree on the decline of semen quality in some areas of the world. Long-term continuous prospective studies are needed for the evaluation and prediction of the general variation trend of semen quality.

5.Effects of androgen on lipoprotein and the cardiovascular system.
National Journal of Andrology 2007;13(10):928-931
The effects of androgen on lipid and the cardiovascular system are very important. The relationship between androgen and lipoprotein is rather complicated and influenced by many factors. The effects of endogenous androgen on the metabolism of lipoprotein vary with age, environment, nutrition and gender, while the effects of exogenous androgen on lipoprotein vary with different androgen preparations, administration methods and diseases to be treated. Androgen can impact the metabolism of lipoprotein, vascular endothelium, macrophage, vascular smooth muscle, angiotasis, blood coagulation, platelet and so on. The effects of polymorphism of the androgen receptor gene CAG on the cardiovascular system are important and yet somehow controversial and have to be further investigated.

6.Predictors for partial suppression of spermatogenesis of hormonal male contraception.
Asian Journal of Andrology 2008;10(5):723-730
AIMTo analyze factors influencing the efficacy of hormonal suppression of spermatogenesis for male contraception.
METHODSA nested case-control study was conducted, involving 43 subjects, who did not achieve azoospermia or severe oligozoospermia when given monthly injections of 500 mg testosterone undecanoate (TU), defined as partial suppressors compared with 855 subjects who had suppressed spermatogenesis (complete suppressors). Sperm density, serum testosterone, luteinizing hormone (LH) and follicle stimulating hormone (FSH) concentrations at the baseline and the suppression phase were compared between partial and complete suppressors. Polymorphisms of androgen receptor (AR) and three single nucleotide variants and their haplotypes of FSH receptor (FSHR) genes determined by polymerase chain reaction (PCR) and DNA sequencing technique were compared between 29 partial and 34 complete suppressors.
RESULTSBaseline serum LH level was higher and serum LH as well as FSH level during the suppression phase was less suppressed in partial suppressors. Additionally, in a logistic regression analysis larger testis volume, higher serum FSH concentrations alone, or interaction of serum LH, FSH, testosterone and sperm concentrations were associated with degree of suppression. The distribution of polymorphisms of AR or FSH receptor genes did not differ between partial and complete suppressors. In cases with incomplete FSH suppression (FSH 0.2 IU/L), the chances of reaching azoospermia were 1.5 times higher in the subjects with more than 22 CAG triplet repeats.
CONCLUSIONPartial suppression of spermatogenesis induced by 500 mg TU monthly injections is weakly influenced by hormonal and clinical features but not polymorphism in AR and FSHR genes.

7.Update of researches on and utilization of screening questionnaires on late-onset hypogonadism in males.
National Journal of Andrology 2008;14(6):555-559
The screening questionnaires on late-onset hypogonadism (LOH) in males are being gradually perfected with the progress in the researches on this problem. Among the more commonly used screeners are the Aging Male Symptoms Scale (AMS), Androgen Deficiency in the Aging Males Questionnaire (ADAM) and Massachusetts Male Aging Survey Questionnaire (MMAS), which are intended for the screening or diagnosis of LOH as well as for the evaluation of its therapeutic results. Nowadays LOH-related researches are mostly concentrated on the utilization of the questionnaires, validation of their sensitivity and specificity, correlation of screening outcomes or some items with serum hormone levels, and comparison of different screening questionnaires, etc. This paper reviews the status quo of the researches on and utilization of screening questionnaires on LOH together with the sensitivity and specificity of the questionnaires.

OBJECTIVETo study (CAG) n polymorphism of the androgen receptor (AR) gene in responders and non-responders of male volunteers who received testosterone undecanoate intramuscular injection for contraception and to explore the effect of the polymorphism on hormonal male contraception.
METHODSTwenty-nine non-responders and 34 responders were enrolled in this study as a test and a control group respectively. The numbers of CAG sequence repeats were determined by PCR and DNA sequencing, and the effect of (CAG) n polymorphism on hormonal male contraception was analyzed.
RESULTSThe means of CAG repeats of the test and the control group were 23.62 and 22.97, with no significant difference in between (P > 0.05). The short CAG repeats (n < or = 22) constituted 51.7% in the test group and 50% in the control, while the long ones (n > 22) accounted for 48.3% and 50% , respectively. The short and the long group had a similar distribution. No association was found between CAG repeats and sperm concentration. With FSH > 0.2 IU/L, the probability of azoospermia in the long CAG repeat group was 1.5 times that of the short one.
CONCLUSIONCAG repeats in the AR gene presented polymorphism in the subjects, with no significant difference between the responders and non-responders. Further investigation has yet to be performed into the relationship of hormonal male contraception with CAG repeats or other factors.

This study was purposed to investigate the effect of triptolide on bortezomib-induced apoptosis in multiple myeloma cell line NCI-H929(H929). MTT assay was applied to detect the inhibitory effects of triptolide and bortezomib alone or combined at different concentrations on H929 cells, the cell apoptosis was assayed by flow cytometry with Annexin V-FITC/PI staining. The results showed that both triptolide (10 - 100 ng/ml) and bortezomib (10 - 100 nmol/L) alone or combination inhibited the proliferation of MM cell line H929 in a concentration-dependent manner. The apoptotic rate of H929 cells in group of triptolide combined with bortezomib was much higher than that in groups of single drug or control; moreover, the apoptotic rate of H929 cells treated by non-inhibitory concentration of triptolide (10 ng/ml) combined with bortezomib (40 nmol/L) for 24 h was significantly higher than that by bortezomib alone (P < 0.05). It is concluded that triptolide can significantly enhance the pro-apoptotic activity of bortezomib in MM cells.
