The Xiangyang reticulate red clay section was newly sampled in high-resolution. The viewpoints different from the previous studies[17] are put forward after studying Munsell color values, weathering degrees, magnetic parame-ters and stable carbon isotopic compositions of the section. They are as follows: (1) The curves of hue, DCB extracted iron (Fed), DCB extracted iron/total iron ratio (Fed/Fet), weathering index (BA) of the section show that the redness is not significantly correlated with the weathering degree of the layers though the uppermost yellow-brown-colored layer is relatively weakly weathered. The variation in hues of the section is possibly attributed to the change of hematite and goethite contents. It is insufficient to determine the existence of the multiple deposit-pedogenesis cycles in the section, like the loess-paleosol sequence in Chinese Loess Plateau, only by the color variation. (2) Magnetic susceptibility (c) values in the non-reticulate and weakly reticulate layers are high; but are quite low in the reticulate red clay layer. The former are more than ten times higher than the latter because of the leaching and collapse of superparamagnetic (SP) and stable single domain (SSD) magnetic particles during the plinthitic processes. Hence, c values in the section are not controlled by weathering and pedogenic processes, and no longer have clear paleoclimatic implication. It is not correct to prove the existence of the multiple deposit-pedogenesis cycles in the section using c curves. (3) The organic d 13C curve of the section illustrates the reduction of forests and increasing of C4 plants in the study area since the late stage of the Qua-ternary period. It could not prove the existence of the multi-ple deposit-pedogenesis cycles in the section either. (4) As a matter of fact, it is difficult to prove the existence of the mul-tiple deposit-pedogenesis cycles in the Xiangyang section like the loess-paleosol sequence in Chinese Loess Plateau using t

reticulate dunes are one of the commonest dune types, and yet the least understood. reticulate dunes at southeastern Tengger Desert are constituted by NE-SW trending primary ridges and nearly vertical secondary ridges. The result of field work studying the morphodynamics and formation mechanism for reticulate dunes in this area shows that the primary ridges were formed by dominant northwest wind and the secondary ridges developed and maintained by alternating dominant wind and subdominant northeast wind on the basis of the primary ridges. Viewed from morphodynamics, reticulate dunes correspond to the complex transverse dune on which the longitudinal element superimposed.

Drug-induced reticulate hyperpigmentation is uncommon. Including the patient described in this report, chemotherapy-associated reticulate hyperpigmentation has only been described in ten individuals. This paper describes the features of a woman with recurrent and metastatic breast cancer who developed paclitaxelinduced reticulate hyperpigmentation and reviews the characteristics of other oncology patients who developed reticulate hyperpigmentation from their antineoplastic treatment. A 55-year-old Taiwan Residents woman who developed reticulate hyperpigmentation on her abdomen, back and extremities after receiving her initial treatment for metastatic breast cancer with paclitaxel is described. The hyperpigmentation became darker with each subsequent administration of paclitaxel. The drug was discontinued after five courses and the pigment faded within two months. Pub Med was searched with the key words: Breast, cancer, chemotherapy, hyperpigmentation, neoplasm, reticulate, tumor, paclitaxel, taxol. The papers generated by the search, and their references, were reviewed. Chemotherapy-induced reticulate hyperpigmentation has been described in four men and six women. Bleomycin, cytoxan, 5-fluorouracil, idarubacin, and paclitaxel caused the hyperpigmentation. The hyperpigmentation faded in 83% of the patients between two to six months after the associated antineoplastic agent was discontinued. In conclusion, chemotherapy-induced reticulate hyperpigmentation is a rare reaction that may occur during treatment with various antineoplastic agents. The hyperpigmentation fades in most individuals once thetreatment is discontinued. Therefore, cancer treatment with the associated drug can be continued in patients who experience this cutaneous adverse event.

为了探讨影响柑橘（Citrus reticulate Blanco.）果实生长发育动态和果实品质变化的因子及机理,为提高栽培管理水平提供理论依据,试验连续3a（2013~2015年）对柑橘不同幼果大小与其果实生长发育动态及品质变化的相关性进行了调查比较。结果表明,（1）幼果大小与果实纵径、横径年生长量及日生长量的生长高峰期在年生长过程中出现的次数和时间有关;在果实年生长量方面,纵径有8~10次生长高峰期,横径有8~9次生长高峰期。在果实日生长量方面,纵径有5~7次生长高峰期,横径有7~9次生长高峰期。（2）柑橘幼果大小与果实纵径日生长量、横径年生长量和横径日生长量的生长高峰期次数呈正相关,与果实纵径年生长量生长高峰期次数呈负相关。（3）柑橘幼果大小与成熟果实单果重、果实纵径、果实横径和果皮厚度呈极显著相关,与果形指数和果汁含糖量呈显著相关。生产上以选留大的幼果效果最好,其次是选留较大幼果。建议把幼果大小作为柑橘疏花疏果的重要依据之一和影响果实生长发育、果实品质变化的重要因素之一。
