In the 1990s, some geologists named the Early Triassic isolated carbonate platform in the Luodian area of southern Guizhou Province in South China as the ＂Great Bank of Guizhou＂. During the past twenty years, this term ＂Great Bank of Guizhou＂ was used in more than 300 articles in foreign countries. In the 1990s, the authors have studied the lithofacies palaeogeography of the Early and Middle Triassic in South China. In June 2014, we went to the Luodian area and studied the Early Triassic Bianyang section again. According to the geological data we acquired, in the Early Triassic of the Luodian area of southern Guizhou Province, there was only an isolated ＂Luodian Carbonate Platform＂, while no bank existed, not to mention the ＂Great Bank of Guizhou＂. It is worth further discussion.

During the past 30 years （1987-2016）, a great progress has been made in researches of soft-sediment deformation structures （SSDS）, seismites and pataeoearthquakes in China. However, the research thought of this academic fietd is not open enough. It is atmost with one viewpoint or one voice, i.e., atmost art the papers pubtished in journals of China considered the layers with SSDS as seismites. On the other hand, the authors are very glad to learn that the professors and students of China University of Petroleum （East China） have proposed different academic viewpoints on the origin of SSDS in Lingshan Istand, Qingdao, Shandong Province, China. It is a very active academic atmosphere. The authors＇ ideas are as follows：（1） The SSDS are sedimentary structures with multi-origin. The term ＂SSDS＂ is a good sedimentary and geological term and shoutd be utilized continuat[y. （2） The term ＂seismites＂ is a term which is definitety assigned to the layers with SSDS induced by earthquakes. It is one type of the tayers with SSDS. It is not equal to SSDS. （3） Some geotogists suggested obsoleting the term ＂seismites＂. These suggestions are rational However, since the term ＂seismites＂ has been utilized for a long time in China and worldwide, to obsolete this term should be discussed and agreement should be acquired from numerous geologists in China and worldwide. It may be suitable that let the geological practice decide whether to obsolete it or not. （4） Hopefully, further progress will be made in the researches of SSDS.

Ranulas are mucoceles that develop as a result of mucous extravasation from the sublingual gland and typically present in the floor of mouth. The treatment of ranulas are various, mainly including surgical and nonsurgical methods. The preferred treatment of oral and plunging ranulas is still uncertain. According to the complications associated with surgical therapy, nonsurgical sclerotherapy has been advocated by clinicians for its advantages of less injury, no scar,less suffering, etc. Recently, it was reported that OK-432 was a relatively effective sclerosing agent for both lymphatic malformations and ranulas, although it has a high rate of recurrence after treating ranulas. Pingyangmycin is another reported conventional sclerosing agent for lymphatic malformations. Herein, we hypothesize that intracystic injection of pingyangmycin may be an optimal method for the treatment of ranulas.

由细菌引起的感染性腹泻,至今仍是世界范围广泛流行的传染病之一。由于耐抗生素病原菌的不断涌现,导致了抗生素药物的治疗效果不佳。因此,研发便捷、有效的疫苗对于细菌性腹泻的预防与治疗尤为重要。针对产肠毒素大肠杆菌、霍乱弧菌与志贺氏痢疾菌这三种最为主要的细菌性腹泻病原菌,设计和筛选了以热不稳定肠毒素亚基蛋白为抗原和黏膜佐剂、霍乱弧菌鞭毛蛋白及志贺毒素亚基蛋白为抗原的三联疫苗。通过工程大肠杆菌获得了相应的抗原与佐剂蛋白,并以海藻酸钙-壳聚糖微球为疫苗的口服载体,制备了疫苗的口服制剂。体外实验表明,微球载体中的蛋白质在模拟胃液中释放较低,但在模拟肠液中释放迅速,这种载体能够实现疫苗在肠道内定向释放的目的。通过对灌胃免疫后小鼠免疫指标的检测,证明了疫苗能够刺激机体产生抗原特异性的sIgA与IgG抗体,免疫组与对照组相比,差异显著(P<0.05),并提升了外周血中CD4^+T细胞的含量(7.5%~9.5%)与CD4^+T/CD8^+T细胞的比率,有效地激活了机体的黏膜免疫与系统免疫,能够对机体起到保护作用。

We report the pronounced low-temperature specific-heat Cpanomalies in the Mg_(59.5)Cu_(22.9)Ag_(6.6)Gd_(11)bulk metallic glass(BMG).The extrapolated electron’s temperature coefficientγ0Kis up to 681.8 mJ/(molGd·K^(2))at 0 K,which is a heavy-fermion-like *** low temperature specific heat indicates an enhancement of the conduction-electron effective mass m*below 7.5 K,suggesting that the Mg_(59.5)Cu_(22.9)Ag_(6.6)Gd_(11)BMG is not free-electron-like *** excess specific heat in the Mg-based BMG is interpreted with tunneling states and spin glass state(magnetism)which are determined by subtracting electrons’and phonons’contribution to the specific heat below 12 *** Boson peak(BP)temperature is located at 27 K,which is much higher than the reported values of other ***,a BP height of 0.047 mJ/(mol·K^(4))is obtained due to reduced free volume during copper mold casting with a slow cooling *** electrical resistivity was also investigated between 2 and 300 K,which has a negative temperature coefficient of resistivity(TCR)below 35 K(Kondo temperature,TK)and a positive value of 3.9×10^(-4)/K above 35 *** is a minimum at about 35 K for the electrical resistivity,which can be explained by the Kondo *** the resistivity above 35 K,it can be explained by the FaberZiman model due to the T-dependence change of structure factor.
