Clinical trials of the new 3-dimensional reticular intrauterine device for reproductive women

Qiu Yi,Wang Leiguang and Yu Ling

Strategic Study of CAE 2014, Volume 16, Issue 5,   Pages 39-46

Abstract:

This study aimed at exploring a new 3-dimensional reticular intrauterine device (3-DR-IUD) composed of nitinol and silicone rubber and observing the contraceptive efficacy and side effects of the device in reproductive women. The frame of the 3-DR-IUD was constructed with silicone rubber and nitinol wire. The 3-DR-IUD was placed into uterus in an outpatient procedure. One hundred and fifty- two women were divided equally into the 3-DR-IUD group (n=76) and the 2- dimensional intrauterine device (2- D- IUD) group (n=76，control group). Patient follow-ups were performed in 1～12 months post-operation. The side effects of intrauterine device (IUD)，such as abnormal leucorrhea，menstrual flow changes in uterine bleeding profusely and pain，etc，were investigated. The pregnancy rate，expulsion rate，removal rate of IUD for medical reasons and the continuation rate were evaluated. The ultrasound and pelvic X-ray were carried out to examine IUDs. The results showed that two groups with 76 cases of each successfully placed IUD and there were no severe pain during the operation. The incidence of lumbago/abdominal pain and the occurrence of leucorrhea and irregular vaginal bleeding in the 3-DR-IUD group (7.9 %，6/76) were significantly lower than that of the 2-DIUD group (40.8 %，31/76) during the first 12 months for use of IUD (P<0.000 1). The pregnancy rate，expulsion rate and take-off rate due to symptom were 0 %，0 % and 1.3 % in 3-DRIUD group，respectively，and 1 of 76 woman take-off 3-DR-IUD was due to allergy for silicon rubber. The continuation rate was 98.7 % (75/76) in the 3-DR-IUD group，comparing with the 2-D-IUD group (86.8 % ，66/76)，the difference was significantly (P=0.009). Therefore，the 3-DR-IUD demonstrates long-term patient tolerability，satisfaction and efficacy as a contraceptive.The 3-DR-IUD appears to be a new，safe and effective devise of contraception.

Overcoming the challenges of conducting translational research in cell therapy

Sowmya Viswanathan, Armand Keating

Frontiers of Medicine 2011, Volume 5, Issue 4,   Pages 333-335 doi: 10.1007/s11684-011-0166-2

Abstract: Cell therapy holds promise in addressing a number of unmet medical needs but despite its considerable impetus, faces numerous challenges including support for translational research in this area. Here, we examine the challenges confronting cell therapy research including the limited funding available for translational research partly due to the uncompetitive nature of required validation studies in cell therapy that of necessity are not hypothesis-driven. Other issues include lack of standardization of definitions of cell products, uncertainty regarding optimum preclinical animal models, duplication of efforts to secure regulatory approval and a lack of uniformity of nomenclature for some cell products. Nonetheless, several initiatives to address all of these issues are underway.

Evolution of partnering contracts — new engineering contract trials

Liu Zhengguang

Strategic Study of CAE 2012, Volume 14, Issue 12,   Pages 81-84

Abstract:

With the development of society, the engineering industry has become very complex, so the traditional construction contract can not meet the requirement of increasingly diversified development of enginee-ring. Therefore, through wide study and discussion, the Institution of Civil Engineers (ICE) agreed to improve the construction contract. In 1993, the new engineering contract (NEC) was launched by ICE to encourage the “team spirit” and establish a good partnership. After nearly 20 years of application, it was proved very effective. In 2009, the Hong Kong Special Administrative Region Government introduced NEC tentatively. The experience of the first project using NEC was introduced in the paper. The project results show that the NEC can save the duration and cost, reduce the contract disputes and increase effectiveness, which enhances the confidence of the engineering industry for introducing NEC.
