In a re-study of regional geology by the China Geological Survey （CGS）, the key problem is in the stratigraphical division and correlation. According to the new isotopic dating of the Mesoand Neoproterozoic in China, there have been great changes in the strata correlation and tectonic explanation. The authors obtained four zircon sensitive high resolution ion micro-probe （SHRIMP） U- Pb datings from the bentonite of the Lengjiaxi Group （822±10 Ma, 823±12 Ma and 834±11 Ma） and Banxi Group （802.6±7.6 Ma） in north Hunan Province, which is considered to be the middle part of the Jiangnan Orogenic Belt. On the basis of the zircon dating mentioned above, the end of the Wuling orogen is first limited in the period from 822 Ma to 802 Ma in one continued outcrop （Lucheng section） in Linxiang city, Hunan Province. Combining a series of new zircon U-Pb datings in the Yangtze and Cathaysia blocks, several Neoproterozoic volcanic events and distribution of the metamorphic rocks in the Jiangnan Orogenic Belt have been distinguished. In the context of the global geodynamics, it is useful to set up a practical and high precision chronological framework and basic and unified late Precambrian section in South China.

To understand the influence of the diagenetic water medium on the isotopic compositions of thermogenic coalbed gas, both hydrous and anhydrous closed-system pyrolyses were performed at temperatures of 250°C to 650°C on an herbaceous marsh peat. Compared to the results of anhydrous pyrolysis, the hydrocarbon gases generated from hydrous pyrolyses have very different hydrogen isotopic compositions. However, the carbon isotopic compositions of the hydrocarbon gases became only slightly heavier in hydrous pyrolysis, compared to that from anhydrous pyrolysis. With the progress of thermal evolution from peat to a more advanced thermal maturity of vitrinite reflectance values（Ro） of 5.5% during the pyrolysis, the difference in the average δD value increased from 52‰ to 64‰ between the hydrous pyrolysis with saltwater and anhydrous pyrolysis and increased from 18‰ to 29‰ between the hydrous pyrolysis with freshwater and anhydrous pyrolysis, respectively. The difference in the average δ^（13）C value was only 1‰–2‰ between the hydrous and anhydrous pyrolysis. The relationships between the δD values of the generated hydrocarbon gases and Ro values as well as among δD values of the hydrocarbon gas species are established. The close relationships among these parameters suggest that the water medium had a significant effect on the hydrogen isotopic composition and a minimal effect on the carbon isotopic composition of the hydrocarbon gases. The results of these pyrolyses may provide information for the understanding of the genesis of coalbed gas from herbaceous marsh material with the participation of different diagenetic water media.

The pulsations and translations of cavitation bubbles obey combined ordinary differential equations,and their nonlinearities are studied by the bifurcation diagram and the phase diagram in a strong ultrasonic *** pulsation can change regularly or irregularly with changing driving pressure in the time *** bifurcation diagrams of the pulsation versus driving pressure show that the pulsations and translations of bubbles have nonlinear characteristics,and the nonlinear translations of bubbles can disorder the pulsations for certain *** of the pulsation can also be caused by nonlinear pulsation *** addition,the phase diagrams also show that the nonlinear translations make a large contribution to the *** same result can also be obtained when the ambient radii of two bubbles are different.

Super-resolution microscopy has promoted the development of cell biology, but imaging proteins with low copy numbers in cellular structures remains challenging. The limited number of designated proteins within nuclear pore complexes(NPCs) impedes continuous observation in live cells, although they are often used as a standard for evaluating various SR methods. To address this issue, we tagged POM121 with Halo-SiR and imaged it using structured illumination microscopy with sparse deconvolution(Sparse-SIM). Remarkably, POM121-SiR exhibited more than six-fold fluorescence intensity and four-fold enhanced contrast compared to the same protein labeled with tandem-linked m Cherry, while showing negligible photo-bleaching during SR imaging for 200 frames. Using this technique, we discovered various types of NPCs, including ring-like and cluster-like structures, and observed dynamic remodeling along with the sequential appearance of different Nup compositions. Overall, Halo-Si R with Sparse-SIM is a potent tool for extended SR imaging of dynamic structures of NPCs in live cells, and it may also help visualize proteins with limited numbers in general.

现关于中医药干预慢性萎缩性胃炎(chronic atrophic gastritis,CAG)的临床研究和基础实验研究已成为消化系统疾病中的研究热点。Janus蛋白酪氨酸激酶(Janus protein tyrosine kinase,JAK)/信号转导子与激活子(signal transducer and activator of transcription,STAT)信号通路的状态与消化道疾病的发生与进展十分密切。诸多研究表明中药可通过多种机制调控该信号通路干预CAG的进展,大致可分为以下几个方面:通过抑制JAK2/STAT3、核转录因子-κB/STAT1通路激活或促使白介素-4(interleukin-4,IL-4)/STAT6激活达到干预CAG的目的;同时降低IL-6、IL-1β等相关炎症因子表达,不仅可抑制相关通路激活,亦可起到减轻胃黏膜炎症的作用;再者上调抑癌基因p21、下调原癌基因表达防止受损的胃黏膜进一步恶化;最后还可调节生存素、B淋巴细胞瘤2家族调控细胞凋亡/增殖平衡机制逆转胃黏膜萎缩及肠化生。

Based on observational data and facsimile charts from Dec. 1994 to Nov. 1995 of Chinese Antarctic Great Wall Station, the local fine weather was studied. Pressure, temperature and humidity field, and aerological stratification were analyzed synoptically. Two kinds of fine weather with different physical characteristics were found; one was caused by the spreading of subtropical high with high tem- perature and high humidity, and another was connected with polar high with low temperature and low humidity. The research provide a synoptic background for the local fine weather forecast.
