Engineering an Organic Nanoplatform for Augmented Pyroeletroimmunotherapy.

Photothermal immunotherapy has shown great promise in the treatment of tumor metastasis. However, the thermal resistance of tumor cells substantially compromises the treatment effect of photothermal immunotherapy. Herein, a high-performance organic pyroelectric nanoplatform, Bu-TPAD-BF nanoparticles (NPs), is rationally engineered for the effective pyroelectroimmunotherapy of tumor metastasis.

[Effect of Grade and Steaming Time on Quality of Cultivated Cistanche deserticola].

Objective: To study the correlation between chemical component content and grades of Cistanche deserticola,and then to determine the optimum steaming time of different grades of Cistanche deserticola.

Methods: Morphological indexes of postharvest stems of Cistanche deserticola were analyzed by principal component analysis and K-mean cluster analysis to determine a grading standard. Concentrations of phenylethanoid glycosides,polysaccharides,dilute ethanol-soluble extracts and total ashes in dried stems of Cistanche deserticola were determined using high performance liquid chromatography and ultraviolet spectrophotometer.

[Influence of dehydration and diurnal variation on characteristics of chlorophyll fluorescence of leaves in Haloxylon ammodendron and H. persicum].

To evaluate the ecological adaptation mechanism of Haloxylon ammodendron and H. persicum from Ningxia, the host of Cistanche deserticola, the chlorophyll fluorescence under dehydration and diurnal variation was determined by IMAGING-PAM method. The results showed that H.

[AFLP analysis on genetic diversity of Haloxylon ammodendron in China].

To determine the genetic diversity of Haloxylon ammodendron collected from 14 sites in 5 provinces, 103 H. ammodendron samples of 12 wild populations and 2 cultivated which collected from 14 sites in 5 provinces were analyzed by amplified fragment length polymorphism (AFLP) DNA markers. PopGen32 and NTSYSpc2.

[Status and prospect of studies on habitat characteristics, parasitic mechanism and nutrient transport of Cistanche deserticola].

Cistanche Herba is one of precious traditional Chinese medicine, which original wild plant resources dropped sharply in recent years. It is urgent to make sustainable utilization. The genus of Cistanche is a total parasitic plant, its physiological ecology and nutrition transfer are very particular.

[Analysis of volatile compounds of inflorescence by GC-MS from Cistanche deserticola].

Objective: To study the volatile compounds from inflorescence of Cistanche deserticola and provide basis for its utilization and seed breeding.

Methods: The volatile compounds were collected by dynamic headspace adsorption and analyzed by gas chromatography-mass spectrometry (GC-MS).

Results: Forty volatile components were identified in inflorescence of Cistanche deserticola from squaring period to full-bloom period.

[FTIR and 2D-IR spectroscopic studies on different sources of Herbra cistanche].

In the present paper, Fourier transform infrared spectroscopy (FTIR) associated with second derivative infrared spectroscopy and two-dimensional correlation spectroscopy (2D-IR) were used to analyze the 3 different sources of Hebra cistanche. The results showed that these IR spectra showed their different macro-fingerprint features: the charactersistic peaks of C. deserticola were located at approximately 1 730, 1 633, 1 156, 1 081, 1 025 and 931 cm(-1) and those of C.

[Identification of Cistanche deserticola from Boschniakla rossica and Cynomorium songaricum using FTIR and two-dimensional correlation IR spectroscopy].

In the present paper, Fourier transform infrared spectroscopy (FTIR) combined with two-dimensional correlation spectroscopy (2D-IR) was used for the identification of Cistanche deserticola from its adulterants, Boschniakla rossica and Cynomorium songaricum. The results showed that these IR spectra showed their different macro-fingerprint feathers: the charactersistic peaks for Cistanche deserticola were located at -1 730 and 931 cm(-1). While absorption peaks at -1 510, 1 375 and 1 266 cm(-1) were only found in Boschniakla rossica.

[Rapid and undamaged determination of C. deserticola by Fourier-transform infrared spectroscopy and clustering analysis].

Cistanche deserticola, an endemic species in China, has been one of the grade II national key conservation rare and endangered plants. The spectra of cultivated and wild C. deserticola samples were determined by Fourier transform infrared (FTIR) spectrometry.

[Studies on seed quality evaluation technique and grading rules of Cistanche deserticola].

Objective: To establish a seed quality evaluation technique system and quality grading rules for Cistanche deserticola.

Methods: We used stereomicroscope, microphotography and image analysis system, tetrazolium method to measure, analyze and evaluate the size, thousand kernel weight, plumpness, embryo rate and viability of Cistanche deserticola seed. Then we used SPSS 11.

[Study on the pollination characteristic of Cistanche deserticola].

Objective: To study the Pollination Characteristic of C. deserticola.

Method: Four pollination methods were used, cross pollination coming different plant, cross pollination in one plant, wind pollination and no-pollination.
