To evaluate the role of nitric oxide in local function of endometrium, the pattern of expression of endothelial and inducible nitric oxide synthases in the human endometrium at proliferative and secretory phases and decidua was studied by using immunocytochemistry. Results showed: (1) At the proliferative phase, the eNOS immunostaining was confined to vascular endothelial, whereas the iNOS was not detected in any composition of endometrium. (2) At the secretory phase, surface epithelium and grandular epithelium showed positive staining for both eNOS and iNOS. The stroma remained uniformly negative throughout the menstrual cycle. (3) In the decidua, the expression of both isoforms was increased, while moderate iNOS immunoreactivity was observed in decidualized stromal cells. It was demonstrated that the expression of eNOS and iNOS was elevated at the secretory phase and in decidua, indicating the increased production of NO at these phases. The increasing of NO might take part in implantation through dilating the vessels and relaxing the smooth muscles and in menstration through promoting apoptosis.

Objective To report the first case of ectodermal dysplasia/skin fragility syndrome in China. Methods The clinical data, transmission electron microscopic examination and immunohistochemical analysis of this patient were evaluated. Results The patient was a 3-year-old girl who presented increased skin fragility with trauma-induced, blisters and erosions, combined with short and sparse hair, finger-and toe-nail dystrophy and palmoplantar keratoderma. Transmission electron microscopy showed a loss of keratinocyte-keratinocyte adhesion, widening of intercellular spaces and a reduced number of hypoplastic desmosomes. Immunohistochemical analysis revealed a complete absence of staining for plakophilin 1. Conclusion Ectodermal dysplasia/skin fragility syndrome is a rare autosomal recessive inherited disease characterized by clinical manifestations as well as electron microscopic features and immunohistochemical evidence.

To evaluate the role of nitric oxide in the embryo implantation in mice, three experiments were carried out using the mice implantation model. In the experimentⅠand experimentⅡ, NG-nitro-L-arginine methyl ester (L-NAME), the non-specific NOS inhibitor, was administered intraperitoneally at doses of 0.5 mg-5 mg on the day 3 of pregnancy and at dose of 3 mg on different days of pregnancy (day 1-6) . In the experiment Ⅲ, L-aragnine, a donor of NO, was co-administered with L-NAME to evaluate the effect of L-aragnine on L-NAME, and the embryo development was assessed. In all these three experiments, the endometrium was histologically examined. Results showed compared with the control groups intraperitoneal administration of a dose of L-NAME between 1 and 5 mg on the day 3 of pregnancy led to the decrease in the number of implantation sites (P<0.05), and 4 to 5 mg of L-NAME caused inhibition of implantation completely. L-NAME resulted in failure of pregnancy when administrated at 3 mg between day 3 and 5 of pregnancy. The characteristic vascular permeability changes and decidualization in the endometrium were significantly attenuated and embryo growth was retarded. The L-NAME-mediated effects were significantly reversed when L-aragnine was co-administered with L-NAME. This study demonstrated that NO promoted the implantation in mice through regulating the permeability and decidulization of endometrium and the development of embryo.

Penile vascular endothelial damage, vasomotor dysfunction, and blood flow deficiency are the major causes of erectile dysfunction (ED). Current management of ED mostly depends on selective phosphodiesterase type 5- (PDE5) inhibitors, which fail for some ED patients. For Peyronie's disease-induced ED, surgical and physical therapies are used in addition to PDE5I medication, but frequently it is difficult to achieve satisfactory results. Recent studies show that the low-intensity extracorporeal shockwave therapy can promote angiogenesis and improve blood flow to the penis, which promises to be a novel effective therapy for ED and Peyronie's disease.

Objective To study the influence of resolving phlegm and relaxing bowels decoction(Huatan Tongfu decoction)on plasma tissue type plasminogen activator(t-PA),plasminogen activator inhibitor(PAI)and homocysteine(Hcy)in patients with acute cerebral infarction. Methods With randomized and controlled clinical research,78 inpatients from 2010 to 2012 in Traditional Chinese Medicine(TCM)Department of Beijing Chaoyang Hospital,Capital Medical University were chosen,including 40 patients in observation group and 38 patients in control group. The patients in control and observation groups were treated by conventional treatment,and additionally the patients in observation group received Huatan Tongfu decoction(ingredients:Trichosanthis 30 g,Arisaema with bile 6 g,Magnolia bark 10 g,Fried rice sprout 15 g),and the rhubarb decoction was made alone,each 20 mL decoction containing crude drug 6 g. 1-4 days after the beginning of the study,the two decoctions were mixed,and the patients took the lukewarm mixture orally twice daily(once 1/2 the dosage);5-12 days after the start of the study, the patients took 200 mL lukewarm mixed decoction daily,being divided into 2 times to administer,and according to the patient defecation situation,the dosage of rhubarb decoction was adjusted individually,the therapeutic course being 12 days. The t-PA,PAI and Hcy were detected before treatment and on the 7th day after treatment. TCM syndrome scores(phlegm syndrome,fire-heat syndrome and sthenic-fu syndrome)were recorded before and on the 12th day after treatment,and the scores of National Institute of Health Stroke Scale(NIHSS)were recorded at the same time. Results Before treatment,the differences in t-PA,PAI,Hcy levels and NIHSS score and phlegm syndrome,fire-heat syndrome and sthenic-fu syndrome scores were not statistically significant;all the indicators improved significantly after treatment compared with those before treatment,and the changes in observation group were more remarkable〔t-PA(mg/L):13.03±2.15 vs. 12.95±2.16,PAI(mg/L):23.64±9.07 vs. 26.81±10.00, Hcy(μmol/L):9.13±1.15 vs. 11.52±3.17,phlegm syndrome:9.16±1.71 vs. 11.17±2.89,fire-heat syndrome:7.51±1.59 vs. 8.81±2.26, sthenic-fu syndrome:0.61±0.87 vs. 1.19±1.14, NIHSS score:5.70±3.16 vs. 5.90±2.97〕. Conclusion The mechanism of Huatan Tongfu decoction in treatment of patients with acute cerebral infarction accompanied by TCM syndromes of phlegm heat and sthenic-fu may be related to the reduction of plasma PAI and Hcy levels,protection of vascular endothelium and promotion of fibrinolysis,thereby the decoction can improve the clinical efficacy.
