| 3 | In vivo fiber photometry of neural activity in response to optogenetically manipulated inputs in freely moving mice显示文摘In vito fber photometry is a powerful technique to analyze the dy namics of population neurons during fiunctional study of neuroscience.Here,we introduced a detailed protocol for fiber photometry-based calciun reording in freely moving mice,covering from virus injection,fiber stub insertion,optogenetical stimulation to data procurement and analysis.Furthemnore,we applied this protocol to explore neuronal activity of mice latenal-posterior(LP)thalaric nucleus in response to optogenetical stimulation of primary visual cortex(V1)neurons,and explore axon clusters activity of optogenetically evoked V1 neurons.Final confirmation of virus-based protein expression in V1 and precise fber insertion indicated that the surgery procedure of this protocol is reliable for functional calcium recording.The scripts for data analysis and some tips in our protocol are provided in details.Together,this protocol is simple,low-cost,and effective for neuronal activity detection by fiber photometry,which will hep neuroscience researchers to carry out fiunctional and behavioral study in vivo. | Liang Li Yajie Tang Leqiang Sun Khaista Rahman Kai Huang Weize Xu Jinsong Yu Jinxia Dai Gang Cao | 2017 | Journal of Innovative Optical Health Sciences2017，，5： | 1 |

| 6 | Preparation and characterisation of solid dispersions of tanshinone ⅡA, cryptotanshinone and total tanshinones显示文摘Total tanshinones are lipophilic active constituents extracted from Salvia miltiorrhiza Bge.Tanshinone ⅡA and cryptotanshinone are the major components in total tanshinones.However, the bioavailability of both compounds is low due to poor water solubility. To enhance the solubility and dissolution rate of tanshinone ⅡA, cryptotanshinone and total tanshinones,three common used hydrophilic carriers including PEG 6000, poloxamer 188 and PVP K30 were used to prepare the solid dispersions at different ratios, respectively. The solid dispersions were characterised by scanning electron microscopy(SEM), differential scanning calorimetry(DSC) and Fourier transform infrared spectroscopy(FTIR). The results of powder X-ray diffraction confirmed the microcrystal state of total tanshinones in solid dispersions and no chemical interaction between total tanshinones and carriers was observed in FTIR spectra. The solubility and dissolution rate of tanshinone ⅡA and cryptotanshinone were significantly increased in all solid dispersions. Regarding tanshinone ⅡA, the solubility and dissolution rate of in solid dispersions prepared with poloxamer 188 were significantly higher than that with PEG 6000 and PVP K30. The higher solubility and dissolution rate of cryptotanshinone were obtained in solid dispersion of PVP K30 than that of PEG 6000 solid dispersions but no significant difference from poloxamer 188 solid dispersions. The results indicate that the superior carrier for preparation of tanshinone ⅡA and total tanshinones solid dispersions is poloxamer 188, and that for cryptotanshinone is PVP K30. | Xifeng Zhai Chunguang Li George Binh Lenon Charlie C.L.Xue Weize Li | 2017 | Asian Journal of Pharmaceutical Sciences2017，12，1： | 1 |

Meiss by the common and variant peak ratio dual indicator sequence method. [Methods] Four different solvents(petroleum ether, chloroform, ethyl acetate and methanol) were used to extract the chemical components of different polar regions of B. sessilicarpa and B. albiflora. UV-visible spectrophotometry(second derivative method) was used to collect the fingerprints of different solvent extracts, and common and variant peak peak ratios were analyzed for the absorption peak data. [Results] The common peak ratio and variant peak ratio data of ground parts of B. albiflora and B. sessilicarpa was S2∶S5(46.2(54.2, 62.5)), compared with the data of other groups, the common peak ratio was the largest, thus the components of ground parts of B. albiflora and B. sessilicarpa were closest and had the largest similarities; the common peak ratio and variant peak ratio data of the components extracted by chloroform from B. albiflora and B. sessilicarpa was Y2∶Y6(54.2(38.5, 46.2)), compared with the data of other groups, the variant peak ratio was the smallest, thus, the chemical components near the chloroform polarity of two kinds of medicinal materials had the largest similarities and smallest differences. [Conclusions] This method is simple and easy to operate, and the ultraviolet fingerprint data of four different polar organic solvent extracts are used for comprehensive analysis, and the results have high specificity and high accuracy. Besides, there are certain similarities and also differences between the chemical components of B. sessilicarpa and B. albiflora. It is expected to provide a new evaluation method for the variety quality of B. sessilicarpa and B. albiflora. | Nannan LONG Risha WEIZE Hairong ZHONG Xiaoxia CAI Yuan LIU Ying LI | 2019 | Medicinal Plant2019，10，2： | 0 |
