Objective To make a preliminary investigation and summary of the technique and efficacy of the novel intracranial stent, Enterprise, together with hydro-detachable coils for the treatment of very small intracranial wide-necked aneurysms (diameter<3 nun and body-to-neck ratio<1.5). Methods Six cases with very small intracranial wide-necked aneurysms were treated with Enterprise stents and hydro-detachable coils. In 5 cases the Enterprise stent was implanted to cover the neck of the aneurysm, which was followed by the introduction of a microcatheter into the aneurysmal sac through the stent mesh to stuff hydro-detachable coils in order to fill the aneurysmal sac. In the remaining case, the microcatheter was placed into the aneurysmal sac before the Enterprise stent was inserted to embolize the aneurysm. Postoperative follow-up was conducted for 3-6 months. Results The operation was successfully completed in all 6 patients, with the implanted stents being in right place. The parent arteries remained patency in all patients. No complications occurred. Complete occlusion of aneurysmal cavity was obtained in four cases, and the occlusion degree of the aneurysmal cavity above 95% was seen in 2 cases. After the procedure, all the patients recovered well. Neither rebleeding nor symptoms related to thrombosis occurred during a clinic follow-up of 3-6 months. Conclusion Endovasculur embolization with Enterprise stent together with hydro-detachable coils is a safe and effective method for the treatment of very small intracranial wide-necked aneurysms. However, its long-term effect needs to be further observed.

Objective To explore the relationship of dynamic changes between the iodine nutritional condition and growth of children born before and after the implementation of universal iodine.Methods By means of sampling investigation,urinary iodine and goiter,height,weight,intelligence quotient(IQ)were comprehensively evahated in children aged 7～14 years old born before and after the implementation of iodine in 10 counties and 2 cities of Qiannan.Results The median of urinary iodine of children Was 91.88μg/L in 1984,133.33μg/L in 1994,316.00μg/L in 2006;goiter rate was 21.40%(122/570)in 1984,12.86%(107/832)in 1994,5.28%(45/851)in 2006;the average IQ was 89.18±4.10 in 1994,94.26±0.94 in 2006;children in each age group in 2006 has a higher height and a heavier weight compared with those in 1984.Conclusion The physical development and intelligence of children in the areas of iodine deficiency have improved along with the correction of iodine deficiency.

Fertility preservation is a hotspot of research in reproductive medicine, and that of male adolescent cancer patients is drawing even more attention from reproductive and oncologic clinicians. Both cancer and its treatment can decrease semen quality and even induce irreversible damage to fertility. Sperm cryopreservation is an effective method for fertility preservation. In the past few years, marked advances have been made in the cryopreservation, transplantation, and in vitro culture of testis tissue and stem spermatogonial cells. Although still experimental, these approaches may offer some options to those with no mature sperm in the testis. Unfortunately, very few people know and participate in the studies of fertility preservation and the utilization rate of cryopreserved sperm remains low. Therefor reproductive physicians and oncologists are required to make more efforts to search for effective fertility preservation methods for male adolescent cancer patients.

Industrialization and environmental pollution are bringing more problems to human reproduction and increasing the prevalence of male infertility. Western medicine has shown its limitations in the management of male infertility, especially that of oligoasthenospermia. Traditional Chinese medicine (TCM), however, has long and rich experiences in the treatment of oligoasthenospermia, with a large variety of medicinal prescriptions based on the TCM theories, among which Qilin Pills shows a particularly significant therapeutic effect on oligoasthenospermia, especially when combined with Western medicine. At present, published studies on Qilin Pills are mainly in the stage of clinical observation, while basic researches and studies on its relevant mechanisms are rarely seen.

Objective::To explore the effect of strong light stress on the growth, physiological and biochemical and key enzyme gene expression of the Atractylodes lancea, in order to provide the scientific basis for the standardized cultivation of the A. lancea. Method::The two-year-old A. lancea seedlings were taken as experimental materials. Poplar forest (light transmittance between 18.26%-36.04%) was taken as control group(ck). Different density shading networks were used to simulate different degrees of high light stress (51.10%, 80.73%, 100%) in late July. The growth state of A. lancea was observed. On the 0^th, 5^th, 10^th, 15^th, 20^th days, the physiological and biochemical indexes of malondialdehyde (MDA) content, cell membrane permeability, proline (Pro) content, antioxidant enzyme activity and chlorophyll content in the leaves of A. lancea were measured. The relative expression levels of 3-hydroxy-3-methylglutarate monoacyl coenzyme A reductase (3-hydroxy-3-methylglutaryl coenzyme A, HMGR) and farnesyl pyrophosphate synthase gene (farnesyl pyrophosphate synthase, FPPS) in leaves of A. lancea under intense light stress were determined by real-time fluorescence quantitative PCR(Real-time PCR). Result::After strong light stress, the color of the leaves of A. lancea changed from dark green to light green and yellowish green, and the burn of leaves became more and more serious. The contents of MDA, conductivity and Pro showed an upward trend with the increase of transmittance. Peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) tended to increase first and then decrease. The chlorophyll content decreased with the increase of light transmittance. The relative expression of HMGR in leaves of A. lancea decreased with the increase of light transmittance, while FPPS increased first and then decreased. Conclusion::The results showed that A. lanceaa could alleviate the inhibition of strong light stress by increasing the activity of antioxidant enzymes and regulating the content of osmotic pressure under certain strong light stress. Excessively strong intensity light stress leads to disequilibrium of metabolic mechanism of A. lancea, and seriously inhibits the plant growth.
