Objective. This work studied the influencing factors of age, level of education, family planning awareness, relationship with partner, the age at which sexual relationships were initiated, parity, the method of contraceptive previously used, the type of contraceptive pill used and the duration of oral hormonal contraception (OC) use in relation to the modification of sexual desire in OC users. Materials and Methods. Prospective study of 760 OC users at the Family Planning Center “Marina Alta” in Alicante (Spain). A logistical regression analysis was carried out to study the relative risk of reduction in libido, taking other risk factors into account. Results. In the simple analysis, women who initiated sexual relationships between 18 and 25 years of age had a lower sexual desire in comparison with women who were sexually active before the age of 18 (OR = 2.11;CI: 1.15 - 3.91). Nulliparous women had a reduced sexual desire compared with those women that had given birth (OR = 2.32;CI: 1.41 - 3.82). An OC use of between 6 months and 1 year reduced sexual desire in comparison with a use of less than 6 months (OR = 0.24;CI: 0.09 - 0.64). In the multivariate analysis, age (OR = 1.12;CI: 1.01 - 1.21) and the use of OC within an initial 6 month to a year period (OR = 0.24;CI: 0.09 - 0.64) presented a statistically significant relationship with the modification of sexual desire. The level of education, family planning awareness, relationship with partner, the method of contraception previously used and the type of contraceptive pill prescribed showed no statistical significance with the modification of sexual desire in OC users. Conclusions. Sexual desire in OC users decreases as a woman’s age increases and in an early stage of use in the first six months after beginning OC treatment.

中国新生代黄土序列具有沉积速率高、连续性好等特点,记录了东亚地区持续的古气候动力学演化和重大地质事件信息。受区域构造-地貌和大气环流格局影响,中生代晚期华南发育了众多盆山型古沙漠系统且出露了巨厚的风成砂,但几乎未有学者提及黄土/黄土类似物的存在。本文通过粒度端元解析、野外露头的构型分析等手段,对衡阳盆地上白垩统红花套组进行了初步研究,识别出风成砂丘、砂席和泥滩等环境类型;并在泥滩环境中提取到黄土类似物的粒度组分信号,同时提出了黄土类似物的风成成因,总结了其形成-堆积过程。这项工作旨在探索白垩纪黄土类似物存在的可能性,为未来开展华南陆块中生代风尘记录研究提供契机。

Objective： Analysis of abstinence rates of smokers per gender at 3, 6, 9 and 12 months in a Smoking Cessation Unit from January 2008 to December 2009. Methods： Descriptive retrospective study. Analysis of socio-demographic variables, smoking patterns, associated comorbidities, continuous abstinence rates, success, relapses, failure and dropping out. Results： 278 smokers started treatment （33%）; 55.4% males and 44.6% females （mean age of 48.3 and 44.06 years, respectively）. The main associated comorbidities were： psychiatric （38.7%）, cardiovascular （dyslipemia 25%） and respiratory （COPD （chronic obstructive pulmonary disease） 9.7%） in females; cardiovascular （dyslipemia 34.4%）, psychiatric （34.4%） and respiratory （COPD 19.5%） in males. VRN （Varenicline） was prescribed in 40.2% males and 32.2% females; NRT （nicotine replacement therapy） was used in 46.6% and 38.7%, respectively; bupropion was employed in 6.5% and 21.8%, respectively. Psychological counseling was offered only to 7.8% males and 8.1% females. The continuous abstinence rates in males at 3, 6, 9 and 12 months were 51.3%, 37.7%, 32.5% and 30.5%, respectively, and were 45.2%, 29.8%, 25.0% and 24.2% for females. Failure was 9.7% for females and 18.8% for males. Success was more frequent for those on VRN （n = 41 males; n = 12 females）. No relapses were indicated for 42 females and 71 males. The percentage of relapses was higher at 3 months （29.0% females, 19.5% males）. Conclusions： The study observed differences in treating abstinence between genders （in the abstinence rates and failure index）. This implies having to consider incorporating the gender variable into the diagnosis, treatment and prevention of smoking.

Biotinylated polyurethane-urea nanoparticles for targeted theranostics in human hepatocellular carcinoma

Nano Research 2015年第5期8卷 1729-1745页

Over the past years, significant efforts have been devoted to explore novel drug delivery and detection strategies for simultaneous therapy and diagnostics. The development of biotinylated polyurethane-urea nanoparticles as theranostic nanocarriers for targeted drug and plasmid delivery, for fluorescence detection of human hepatocellular carcinoma cells, is described herein. These targeted nanoparticles are specifically designed to incorporate biotin into the polymeric matrix, since many tumor types overexpress receptors for biotin as a mechanism to boost uncontrolled cell growth. The obtained nanoparticles were spherical, exhibited an average diameter ranging 110-145 nm, and showed no cytotoxicity in healthy endothelial cells. Biotinylated nanoparticles are selectively incorporated into the perinuclear and nuclear area of the human hepatocellular carcinoma cell line, HepG2, in division, but not into growing, healthy, human endothelial cells. Indeed, the simultaneous incorporation of the anticancer drugs, phenoxodiol or sunitinib, together with plasmid DNA encoding green fluorescent protein, into these nanoparticles allows a targeted pharmacological antitumor effect and furthermore, selective transfection of a reporter gene, to detect these cancer cells. The combined targeted therapy and detection strategy described here could be exploited for liver cancer therapy and diagnostics, with a moderate safety profile, and may also be a potential tool for other types of cancer.

Erythropoietin： From a Biosimilar to Innovative Products Protected by Industrial Property Assets

引用

Journal of Pharmacy and Pharmacology 2017年第9期5卷 681-687页

作者： Lien lopez Matilla pedro Barzaga Fernandezt Sonia Gonzalez Blanco Patent Office Centro de Inmunologia Molecular Havana 11300 Cuba Patent Office Center for Pharmaceutical Research and Drug Development Havana 10600 Cuba Patent Office Center for Genetic Engineering and Biotechnology Havana 11300 Cuba

Aim： EPO （erythropoietin） is a hormone that stimulates the erythropoiesis and is mainly produced by the kidneys. In the early 1990s among the emerging biotech drugs, the recombinant human EPO （rhEPO） was the best-selling product worldwide, reaching nearly three billion dollars annually. The CIM （center of molecular immunology） produced and sold the rhEPO as commercial strategy to recover the investment made in its new facilities. This work summarizes the inventions that protect the innovative products developed by three Cuban institutions, starting from rhEPO, and the industrial property strategy followed by them. Methods： The information was obtained from the United States Patent, Trademark Office （USPTO） database, Patentscope, Espacenet, patent databases of Center for Pharmaceutical Research and Drug Development （CIDEM） and Cuban Industrial Property Office. Conclusions： The manufacturing process of CIM＇s EPO has its own patent family. From a manufacturing by product an innovative formulation protected by patent was obtained. There is a patent family around the nasal formulation and it continues enlarging. From a biosimilar pharmaceutical innovative products impacting on human health have been obtained.
