[Multivariate analysis of influencing functional recovery after ankle fracture of typeⅡand above supination-external rotation].

Objective: To explore influencing factors of functional recovery after ankle fracture of typeⅡdegree and above supination-external rotation.

Methods: Clinical data of 120 patients with ankle fractures of typeⅡdegree and above supination-external rotation admitted from February 2019 to April 2021 were retrospectively analyzed. According to American Orthopaedic Foot and Ankle Society (AOFAS), patients were divided into excellent group with 73 patients (90 to 100 points), good group with 35 patients (75 to 89 points), and fair group with 12 patients(<50 points).

Effects of Aging Treatment on Corrosion Behavior of a Tensile Deformed Al-Cu-Mn-Fe-Zr Alloy in 3.5% NaCl Solution.

In this paper, the effects of an aging treatment on the corrosion resistance/mechanism of a tensile deformed Al-Cu-Mn-Fe-Zr alloy are investigated. The impedance magnitude and polarization resistance increase, while the corrosion current decreases with the increased aging time and temperature. The discontinuously-distributed precipitates and precipitation-free zone, which can cut the corrosion channels, appear at grain boundaries when the temperature is relatively high and the aging time is relatively long.

[Study on the chemical constituents of Phlomis younghusbandii].

Objective: To study the chemical constituents of Phlomis younghusbandii.

Methods: Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data

Results: Eight compounds were isolated and their structures were identified as barlerin (1), sesamoside (2), phloyoside II (3), salidroside (4), shanzhiside methyl ester (5), acteoside (6), luteolin-7-O-glucoside (7), daucosterol (8).

[Progress in application of infrared spectroscopy and comparative study of chromatographic fingerprints].

The newest development of applications of IR techniques to the identification of Chinese herbs, the discrimination of folk medicine herbs, Chinese herbs processing and Chinese traditional injection, which involving enhancing computer analysis depth, intensifying the pre-treatment of Chinese herb and using 2D-IR correlation spectroscopy for processing control, was elaborated in the present paper. Meanwhile, the establishment of multi-component determination analysis system of chromatographic fingerprint diagram was shown. And the sameness and difference of the IR spectroscopy and chromatography fingerprint diagram techniques were analyzed, and a comparison was made in terms of quality control of Chinese herbal medicine.
