In the North China Plain(NCP), soil deterioration threatens winter wheat(Triticum aestivum L.) production. Although rotary tillage or plowing tillage are two methods commonly used in this region, research characterizing the effects of mixed tillage on soil characteristics and wheat yield has been limited. A fixed-site field trial was carried out during 2011–2016 to examine the impacts of three tillage practices(5-year rotary tillage with maize straw removal(RT);5-year rotary tillage with maize straw return(RS);and annual RS and with a deep plowing interval of 2 years(RS/DS)) on soil characteristics and root distribution in the plough layer. Straw return significantly decreased soil bulk density, increased soil organic carbon(SOC) storage and SOC content, macro-aggregate proportion(R_(0.25)) and its stability in the plough layer. The RS/DS treatment significantly increased the SOC content, total nitrogen(TN), and root length density(RLD) in the 10–40 cm layer, and enhanced the proportion of RLD in the 20–30 and 30–40 cm layers. In the 20–30 and 30–40 cm layers, an increase in SOC and TN could lead to higher grain production than commensurate increases in the surface layer, resulting in a sustainable increase in grain yield from the RS/DS treatment. Thus, the RS/DS treatment could lead to high productivity of winter wheat by improving soil characteristics and root distribution at the deeper plough layer in the NCP.

Straw return is an important management tool for tackling and promoting soil nutrient conservation and improving crop yield in Huang-Huai-Hai Plain, China. Although the incorporation of maize straw with deep plowing and rotary tillage practices are widespread in the region, only few studies have focused on rotation tillage. To determine the effects of maize straw return on the nitrogen （N） efficiency and grain yield of winter wheat （Triticum aestivum L.）, we conducted experiments in this region for 3 years. Five treatments were tested：（i） rotary tillage without straw return （RT）; （ii） deep plowing tillage without straw return （DT）; （iii） rotary tillage with total straw return （RS）; （iv） deep plowing tillage with total straw return （DS）; （v） rotary tillage of 2 years and deep plowing tillage in the 3rd year with total straw return （TS）. Treatments with straw return increased kernels no. ear-1, thousand-kernel weight （TKW）, grain yields, ratio of dry matter accumulation post-anthesis, and nitrogen （N） efficiency whereas reduced the ears no. ha-1 in the 2011-2012 and 2012-2013 growing seasons. Compared with the rotary tillage, deep plowing tillage significantly increased the grain yield, yield components, total dry matter accumulation, and N efficiency in 2013-2014. RS had significantly higher straw N distribution, soil inorganic nitrogen content, and soil enzymes activities in the 0-10 cm soil layer compared with the DS and TS. However, significantly lower values were ob- served in the 10-20 and 20-30 cm soil layers. TS obtained approximately equal grain yield as DS, and it also reduced the resource costs. Therefore, we conclude that TS is the most economical method for increasing grain yield and N efficiency of winter wheat in Huang-Huai-Hai Plain.

Resveratrol reestablishes spermatogenesis after testicular injury in rats caused by 2,5-hexanedione

Chinese Medical Journal 2008年第13期121卷 1204-1209页

作者： JIANG yong-guang PENG Tao luo yong li Ming-chuan liN Yun-hua Department of Urology Beijing Anzhen Hospital Capital Medical University Beijing 100029 China

Background Environmental toxins can destroy the physiological process of spermatogenesis and even lead to male infertility. Resveratrol （RES） is a natural phytoalexin with a wide range of biological activities. Some recent researches have demonstrated that RES can increase sperm output and protect sperm from apoptosis caused by physical damage. However, there is no evidence indicating that it can also exhibit a similar activity in testis injury caused by environmental toxins. This study was designed to evaluate the protective effect of resveratrol on testis damaged by environmental toxins and to elucidate the possible mechanism of its protective effect. Methods In this study 2,5-hexanedione （2,5-HD） was used as the injury agent. Forty male SD rats were randomly divided into 5 groups. During the first 5 weeks, group A was raised normally, groups B, C, D and E were exposed to 1% 2,5-HD; during the following 9 weeks, group C, D, E received intragastric administration of different concentrations of resveratrol （20 mg·kg^-1·d^-1, 40 mg·kg^-1·d^-1 and 80 mg·kg^-1·d^-1）, while groups A and B were treated by carboxymethylcellulose. Physical signs, body weight gain and testis weight were comparatively observed. Numbers and diameters of seminiferous tubules were analyzed following HE staining. In addition, expression of the c-kit protein and gene in spermatogenic cells in every group was detected with immunohistochemistry, Western blot or RT-PCR. Results The 2,5-HD treatment resulted in physical signs that became worse and in emarciated testis. HE staining and immunohistochemistry showed that seminiferous tubules became emarcid, obsolete spermatogonia being stagnant and expression of c-kit protein being depressed. After oral administration of resveratrol, the 2,5-HD-induced physical signs were improved and close to the normal rats. The gain of body weight increased （P 〈0.01）. The recovery of testis weight was significant （P 〈0.01）. At the histological level, the seminifer

To monitor the extent and the duration of lymphocyte subset changes in patients with thyroid carcinoma undergoing therapeutic 131I administration, the percentage of lymphocyte subsets were serially analyzed before and after 131I treatment. In patients who received 1850 MBq of 131I for ablation of thyroid remnants, only for NK cells and B cells showed a significant reduction. In patients received 3700 MBq of 131I for treatment of local lymph node me-tastases, NK cells, B cells and CD4+ were found decreased. In patients received 7400 MBq of 131I for treatment of distant metastases, NK cells, B cells and CD4+ and CD8+ were all affected. However, there is no significant reduc-tion compared to the baseline in the percentage of all lymphocyte subsets three months after 131I treatment. The re-sults show that the sensitivity of lymphocytes to 131I internal radiation depends upon lymphocyte phenotype and 131I activity. The immunosuppression effects are temporary and reversible.
