OBJECTIVETo search for the optimal strategies for sperm collection from the patient with temporary penile erectile dysfunction (ED) on the day of oocyte pick-up ( OPU) in in vitro fertilization embryo transfer (IVF-ET).
METHODSWe retrospectively analyzed 93 cases of temporary ED on the OPU day of IVF-ET from January 2011 to May 2014, with fresh semen for 45 cases (group A), cryopreserved sperm before oocyte retrieval for 30 cases (group B), and frozen oocytes for 18 cases (group C). Group A was again subdivided into A1 (n = 18) and A2 n = 27) , the former intervened with oral sildenafil while the latter left untreated. We compared the rates of fertilization, high-quality embryo, and pregnancy among different groups.
RESULTSNo statistically significant differences were found among groups A, B and C in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and rates of cleavage, or in the percentages of normal fertilization (80.78% vs 80.43% vs 84.77%), high-quality embryo (53.27% vs 52.97% vs 47.69%) and pregnancy (60.00% vs 56.77% vs 44.44%) (all P > 0.05). The rate of 3PN was markedly lower in group C (0.63%) than in A (9. 61%) and B (4.34%) (P < 0.05). There were no significant differences between groups A1 and A2 in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and the rates of fertilization, cleavage, high-quality embryo, and pregnancy (all P > 0.05).
CONCLUSIONOn the OPU day of IVF-ET, oral sildenafil can help temporary ED men to achieve penile erection and ejaculation without affecting the outcomes of assisted reproduction. Cryopreserved sperm can be used in case of predicted temporary ED and frozen oocytes can also be employed if sperm retrieval fails. However, to avoid puncture injury to the epididymis or testis, fresh semen should be the first choice.

Objective To evaluate the relationship between carotid plaque neovascularization and coronary heart disease using contrast-enhanced ultrasound. Methods We studied carotid plaques in 312 patients with coronary artery disease by contrast-enhanced ultrasound [51 patients with acute coronary syndrome (ACS) and 261 patients with stable coronary artery disease (sCAD) ]. We analyzed sonographic features of each plaque, including the enhancement intensity of plaque (A value), the ratio of plaque to carotid artery lumen in enhancement intensity (Ratio), plaque thickness and plaque echo (soft plaque, hard plaque, mixed plaque, calcified plaque). Results The average thickness of plaque in patients with ACS and in patients with sCAD had no significant difference in statistics [(2.6±0.4) mm vs (2.9±0.8) mm, t=-1.903, P=0.058) ]. The group with ACS:soft plaque 43 (84.3%, 43/51), mixed plaque 8 (15.7%,8/51), no hard plaque and calcified plaque. And the group with sCAD:soft plaque 174 (66.7%,174/261), hard plaque 19 (7.3%,19/261), mixed plaques 16 (6.1%,16/261), calcified plaque 52 (19.9%,52/261). The percentage of soft plaque in the acute coronary syndrome group was significantly higher than that in stable coronary artery disease group (χ2=6.274,P=0.012). The A value and Ratio in patients with ACS were prominently larger than those in patients with sCAD [ (11.3±3.2) vs (8.9±3.3) dB, t=7.150,P<0.01;0.6±0.2 vs 0.4±0.2, t=7.419,P<0.01].Conclusion Carotid artery plaque neovascularization density was significantly higher in patients with ACS than that in patients with sCAD by using contrast-enhanced ultrasound, revealing that the neovascularization density is closely related to clinical symptoms of patients with coronary heart disease.

The paper aimed to elucidate the specific impact of supramolecular chemistry on the Chinese medicine theories (CMT) in their modernization, after had summarized up the research status of supramolecular chemistry and analyzed the possible supramolecular forms of Chinese medicine (CM), as well as considered the problems in modernization of CM theories. On comparison of the classical chemistry that delt with chemical bonds among atoms, the supramolecular chemistry was rather concerned with varietes of weak noncovalent bonds intermolecules, and reflected the macro-apparent chemical properties of each molecules, and was the most appropriate chemical theories to explain the CMT and microcosmic materials. The molecules in the human body and Chinese material medica (CMM) formed supramolecules by way of self-assembly, self-organization, self-recognition and self-replication, with themselves or with complexation, composition, chelation, inclusion, neutralization etc. Meridian and Zang-fu viscera in CMT might be a space channel structure continuously consisted of unique molecules cavity that was imprinted with the supramolecularly template inside and outside of cells, through which the molecules in CMM interacted with the meridian and Zang-fu viscera. When small molecules in human body imprinted with macromolecules in meridian and Zang-fu viscera, in other words, they migrated along within imprinting channels of meridian and Zang-fu viscera on behavior of "Qi chromatography" impulsed by the heart beat, finally showed up on macroscopic the anisotropy of tissue and organ, as described namely as visceral manifestation in Chinese medical science. When small molecules in CMM interacted with imprinting channel on meridian and Zang-fu viscera, the natural properties and efficacy regularities of CMM was reflected on macroscopic. Therefore, the special representation forms of basic CMT is based on the macroscopic expression of "Qi chromatography" abided by imprinting effect regularities, and on whether the imprinted template of small molecules matched with cavity template of macromolecules in meridian and Zang-fu viscera, only is the adequate representation of supramolecular chemistry for them. The CMM materials is the mixture including single molecules and supramolecules. The compatibility for CM prescriptions can significantly change the function rules. Therefore in the study of basic CMT, we should pay special attention to the laws of supramolecular chemistry. It is the most essential differences of the CMT from the modern medicine which established by the laws of single molecular theories.

OBJECTIVETo detect the character of surgical treatment of massive soft tissue sarcoma in the shoulder girdle and analyze the impact factor to the result.
METHODSSeven patients with massive soft tissue sarcoma in the shoulder girdle were treated in our department between 2005 and 2009. There were 4 males and 3 females. All the patients were referred to our hospital after local recurrence post-operatively. The mean age was 43.8 years old (range 14 - 75). The maximum diameter of the tumor varied from 10 to 16 centimeters. All the patients were performed surgery, wide margin in 4 cases and marginal margin in 3 cases. Five were performed tumor resection and reconstruction with latissimus dorsi muscle flap transfer and skin graft. One was reconstructed with advanced skin flap and skin graft. The other one was treated with skin graft. The diagnosis included 3 malignant fibrous histiocytomas, 1 low grade myxoid fibrosarcoma, 1 Primitive neuroectodermal tumor, 1 rhabdomyosarcoma, 1 dermatofibrosarcomas protuberans. The MSTS score system was used to evaluate the shoulder function.
RESULTSSeven patients were followed up with long time. The mean follow up was 29 months (range 10 to 46 months). Two patients suffered local recurrence and one died of pulmonary metastasis 6 months after the second surgery for local recurrence. One patient suffered pulmonary metastasis. The last four patients were disease-free at the end of follow-up. The function of shoulder girdle was satisfactory. The mean MSTS score was 28.
CONCLUSIONSSoft tissue sarcomas in the shoulder girdle are easy to be misdiagnosed and mistreated. Wide surgical margin was the key impact factor to the local recurrence of soft tissue sarcoma in the shoulder girdle. The surgical margin and invasion of the tumor are the key factor to the prognosis. The soft tissue defect after surgery is often reconstructed by muscle flap transfer or skin flap transfer. The latissimus dorsi muscle flap transfer is often used.
