| 1 | Spatiotemporal characteristics of GNSS-derived precipitable water vapor during heavy rainfall events in Guilin,China显示文摘Precipitable Water Vapor(PWV),as an important indicator of atmospheric water vapor,can be derived from Global Navigation Satellite System(GNSS)observations with the advantages of high precision and all-weather capacity.GNSS-derived PWV with a high spatiotemporal resolution has become an important source of observations in mete-orology,particularly for severe weather conditions,for water vapor is not well sampled in the current meteorological observing systems.In this study,an empirical atmospheric weighted mean temperature(Tm)model for Guilin is estab-lished using the radiosonde data from 2012 to 2017.Then,the observations at 11 GNSS stations in Guilin are used to investigate the spatiotemporal features of GNSS-derived PWV under the heavy rainfalls from June to July 2017.The results show that the new Tm model in Guilin has better performance with the mean bias and Root Mean Square(RMS)of−0.51 and 2.12 K,respectively,compared with other widely used models.Moreover,the GNSS PWV estimates are validated with the data at Guilin radiosonde station.Good agreements are found between GNSS-derived PWV and radiosonde-derived PWV with the mean bias and RMS of−0.9 and 3.53 mm,respectively.Finally,an investigation on the spatiotemporal characteristics of GNSS PWV during heavy rainfalls in Guilin is performed.It is shown that variations of PWV retrieved from GNSS have a direct relationship with the in situ rainfall measurements,and the PWV increases sharply before the arrival of a heavy rainfall and decreases to a stable state after the cease of the rainfall.It also reveals the moisture variation in several regions of Guilin during a heavy rainfall,which is significant for the moni-toring of rainfalls and weather forecast. | Liangke Huang Zhixiang Mo Shaofeng Xie Lilong Liu Chuanli Kang Shitai Wang | 2021 | Satellite Navigation2021，2，1： | 6 |
| 2 | Cloning of two plastid division ftsZ genes from Nicotiana tabacum and their expression in E. coli显示文摘Two cDNAs of plastid division gene NtFtsZ1-1 and NtFtsZ1-2 are isolated from Nicotiana tabacum by RT-PCR and rapid amplification cDNA ends (RACE) method. Analysis of the deduced amino acid sequences encoded by NtFtsZ1-1 and NtFtsZ1-2 indicate that these two proteins possess the typical conservative motifs and GTP binding sites existing in all FtsZ proteins. The existence of putative plastid transit peptide in their N-terminal suggests that there are at least two transit-peptide containing FtsZ proteins in higher plants. Phylogenetic analysis based on amino acid sequences of FtsZ proteins also supports this interference. These two NtFtsZ genes demonstrate a similar expression pattern during the plant development, detected by Northern blot. Expression of NtFtsZ1-1 and NtFtsZ1-2 in E.coli interrupts the normal division process of host cells. These results suggest the diverse functions of FtsZ proteins in higher plants. | WANG Dong KONG Dongdong HU Yong JU Chuanli HE Yikun and SUN Jingsan(1.

| 4 | Effect of interleukin-2 on neurogliocyte and neuron apoptosis in rat models of acute spinal cord injury显示文摘BACKGROUND:Interleukin-2 (IL-2) may influence the growth and survival of nerve cells following spi-nal cord injury and resuscitate the proliferation and maturation of oligodendrocytes. OBJECTIVE: To observe the effect of IL-2 on neuronal apoptosis of neurogliocytes at different times fol-lowing acute spinal cord injury in rats. DESIGN,TIME AND SETTING: A randomized grouping trial based on cellular morphology was per-formed at the Institute of Traumatic Orthopedics of Shandong Province between October 2004 and January 2006. MATERIALS: A total of 72 adult,male,Sprague Dawley rats were included in this study and were divided into a control group and an IL-2 group. The Bcl-2 monoclonal antibody and TUNEL kit were purchased from Wunan Boster Biological Technology Corporation. METHODS: Spinal cord injury was induced in all the rats by dropping a weight from a height of 25 cm onto the exposed spinal cord at vertebral levels T7-11,thus producing a mild lesion. Immediately following the modeling,the rats were injected with daily IL-2 (10 μL) intramuscularly (the IL-2 group). Other rats re-ceived an injection of physiological saline 0.5 mL/d (the control group). MAIN OUTCOME MEASURES: Bcl-2 immunohistochemistry was applied to detect the Bcl-protein and positive cell expression. The TUNEL method was used to count the number of apoptotic cells. RESULTS: The expression level of Bcl-2 proteins increased significantly in spinal cord tissues during the first day after acute spinal cord injury,reaching a peak on days 3 and days 8 in the control and IL-2 groups,respectively. They were more prevalent in neurogliocytes than in neurocytes,and then began to decrease on day 14. From then until day 21,less expression was detected (P < 0.05). In the control group,many apoptotic cells existed after 24 hours,and most of them were gliocytes; apoptotic cells reached a peak after 3-8 days. They then decreased gradually until day 21,when a small number of cells were still available. In the IL-2 group,the number of positive cells was significantly lower than in the control group (P < 0.05). CONCLUSION: The expression of Bcl-2 and the number of apoptotic cells in neurogliocytes undergo simi-lar changes with time after acute spinal cord injury. IL-2 may upregulate the expression of Bcl-2 proteins and decrease cell apoptosis in spinal cord tissue. | Chuanli Zhou Xiaoliang Chen Ying Wang | 2008 | Neural Regeneration Research2008，3，11： | 1 |

| 7 | Bird nest-like zinc oxide nanostructures for sensitive electrochemical glucose biosensor显示文摘In this research,a novel bird nest-like zinc oxide(BN-ZnO)nanostructures were prepared by a simple solvothermal method.A sensitive electrochemical glucose biosensor was for the first time developed based on the immobilization of glucose oxidase(GOx)on nanostructured BN-ZnO modified electrode.The BN-ZnO nanostructure and the resultant biosensor were characterized by scanning electron microscope,X-ray diffraction spectroscopy,Fourier transform infrared spectroscopy,and electrochemical impedance spectroscopy.BN-ZnO nanostructures have large specific surface area and can load large amounts of GOx molecules.Meanwhile,BN-ZnO provides an excellent microenvironment to retain the native bioactivity of enzymes and to promote direct electron transfer between GOx and electrode surface.The proposed biosensor shows a wide linear range of 0.005–1.6 mmol/L,high sensitivity of15.6 mA L mol^(-1)cm^(-2)with a low detection limit of 0.004 mmol/L.The resulting biosensor also shows excellent selectivity,acceptable stability and reproducibility,and can be successfully applied in the detection of glucose in human serum samples at-0.37 V. | Feng Shi Jinming Xu Zhongfang Hu Chuanli Ren Yadong Xue Yongcai Zhang Juan Li Chengyin Wang Zhanjun Yang | 2021 | Chinese Chemical Letters2021，32，10： | 1 |

| 18 | ftsZ gene and plastid division显示文摘Plastid is one of the most important cellularorganelles, the normal division process of plastid is essential for the differentiation and development of plant cells. For a long time, morphological observations and genetic analyses to special mutants are the major research fields of plastiddivision, but the molecular mechanisms underlying plastiddivision are largely unknown. Because of the endosymbiotic origin, plastid division might have mechanisms in common with those involved in bacterial cell division. It has beenproved that several prokaryotic cell division genes also par-ticipate in the plastid division. Recently, the mechanisms of prokaryotic cell division have been well documented, which provides a valuable paradigm for understanding the plastid division mechanisms. In plants, the functional analyses of ftsZ, a key gene involved both in bacteria and plastid division, have established the solid foundation for people to under-stand the plastid division in molecular level. In this paper we will make a review for the research history and progress of plastid division. | KONG Dongdong WANG Dong HU Yong JU Chuanli WANG Yingdian HE Yikun SUN Jingsan | 2003 | Chinese Science Bulletin2003，48，12： | 1 |

| 20 | Multiple Kernel Clustering Based on Self-Weighted Local Kernel Alignment显示文摘Multiple kernel clustering based on local kernel alignment has achieved outstanding clustering performance by applying local kernel alignment on each sample.However,we observe that most of existing works usually assume that each local kernel alignment has the equal contribution to clustering performance,while local kernel alignment on different sample actually has different contribution to clustering performance.Therefore this assumption could have a negative effective on clustering performance.To solve this issue,we design a multiple kernel clustering algorithm based on self-weighted local kernel alignment,which can learn a proper weight to clustering performance for each local kernel alignment.Specifically,we introduce a new optimization variable-weight-to denote the contribution of each local kernel alignment to clustering performance,and then,weight,kernel combination coefficients and cluster membership are alternately optimized under kernel alignment frame.In addition,we develop a three-step alternate iterative optimization algorithm to address the resultant optimization problem.Broad experiments on five benchmark data sets have been put into effect to evaluate the clustering performance of the proposed algorithm.The experimental results distinctly demonstrate that the proposed algorithm outperforms the typical multiple kernel clustering algorithms,which illustrates the effectiveness of the proposed algorithm. | Chuanli Wang En Zhu Xinwang Liu Jiaohua Qin Jianping Yin Kaikai Zhao | 2019 | Computers, Materials & Continua2019，，7： | 0 |
