OBJECTIVE To compare the changes of chemical components of Morus alba leaves， screen differential markers， and determine their contents， so as to provide reference for quality control of M. alba leaves before and after baked with honey. METHODS The fingerprints of M. alba leaves before and after baked with honey were established by high-performance liquid chromatography （HPLC）. The common peaks of the fingerprints were identified and the similarity was evaluated. The differential markers of M. alba leaves before and after baked with honey were screened by principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） using common peak are of raw material and product baked with honey of M. alba leaves as index. The quantitative analysis was carried out. RESULTS Twenty-three and twenty-four common peaks were identified from the HPLC fingerprint spectra of ten batches of raw material and ten batches of product baked with honey of M. alba leaves， respectively. The similarities of HPLC fingerprints for raw material and product baked with honey of M. alba leaves were all greater than 0.97. The results of PCA showed that raw material and product baked with honey of M. alba leaves could be divided into two categories. The results of OPLS-DA showed that the variable importance in projection of peak 2， peak H （5- hydroxymethylfurfural）， peak 1， peak 17 （isochlorogenic acid C） and peak 16 were all greater than 1. The average contents of differential marker of isochlorogenic acid C in raw material and product baked with honey of M. alba leaves were 0.093 6 and 0.127 8 mg/g， respectively； there was statistical significance （P＜0.05）. CONCLUSIONS Five differential markers such as isochlorogenic acid C are obtained. The content of isochlorogenic acid C in M. alba leaves is significantly increased after baked with honey.

OBJECTIVE To establish the fingerprint of the ethanol extract from Callicarpa nudiflora， analyze its anti- respiratory syncytial virus （RSV） activity in vitro， and study the relationship between spectrum and effect. METHODS Using 10%， 30%， 50%， 70% and 90% ethanol as solvent， 20 batches of ethanol extracts from 4 batches of C. nudiflora were prepared. The fingerprints for 20 batches of ethanol extracts from C. nudiflora were mapped by ultra-high-performance liquid chromatography （UPLC）， and the similarity evaluation was conducted by using the Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprints （2012 edition）. The cytopathic effect method and MTT method were used to investigate the in vitro inhibitory activity of the ethanol extracts from C. nudiflora on RSV. Pearson correlation analysis， grey correlation degree and orthogonal partial least squares （OPLS） analysis were used to study the spectrum-effect relationship. RESULTS There were 25 common peaks in 20 batches of ethanol extracts from C. nudiflora， and the similarities ranged from 0.912 to 0.998， and the RSDs of common peak areas were 33.54%-162.28%. The average values of IC50 for RSV of 20 batches of ethanol extracts from C. nudiflora were 9.55-272.23 μg/mL. The results of Pearson correlation analysis， grey correlation analysis and OPLS analysis showed that the Pearson correlation coefficients （P＜0.05） of the common peaks 8， 10， 12， 16， 18-19， 22-24 with pharmacodynamic indicators and regression coefficients were all negative， the correlation coefficients were all greater than 0.6， and the values of variable importance in projection were all greater than 1. CONCLUSIONS Twenty batches of ethanol extracts from C. nudiflora have similar components but significant differences in content， and exhibit different degrees of anti-RSV activity in vitro. The corresponding components of common peaks 8， 10， 12， 16， 18-19， 22-24 may be the characteristic components of anti-RSV of C. nudiflora.

Objective:To summarise the experience in use of sural neurouascular flap in repair of the soft tissue defects of foot and ankle, and explore the methods in promoting the survival and appearance of the flap.Methods:Data of 10 patients who underwent sural neurocutaneous flap surgery for repairing soft tissue defects in the foot and ankle in the Department of Foot and Ankle of Xuzhou Renci Hospital from October 2019 to June 2020 were retrospectively analysed. Among the 10 patients, 8 were males and 2 were females, and the age ranged from 18 to 54 years old, with an average age of 42.5 years old; Causes of injury: 8 patients injured by traffic accident and 2 by incision necrosis after calcaneal fracture operation. The areas of soft tissue defect were 4.0 cm×6.0 cm-16.0 cm×10.0 cm. Sural neurouascular flap was used for the defect repairs. Method of optimisation: ①The small saphenous vein in the flap was separated and retained in the limb to optimise the venous circulation. ②Freed peroneal perforator vessels that entered the pedicle, and made the point where the vessels entering the pedicle as the rotation point. The pedicle contained the sural neurovascular bundle, the main trunk of the small saphenous vein and the fascia tissue, with a width about 2.0 cm. It not only increased the blood supply of the flaps, but also a good appearance of the pedicle. ③ The torsion of the pedicle was covered by an arc-shaped flap and transferred through an open channel to prevent compression. ④The donor site was covered with relay flap. According to the location of the donor site, a proximal peroneal artery perforator flap or medial and lateral sural artery perforator flap was selected. ⑤Sural nerve was anastomosed with the peripheral sensory nerve in some cases. The survival of the flap, Maryland Foot Function Score and British Medical Research Council (BMRC) sensory function evaluation were investigated in the follow-up to evaluate the functional recovery of the flap and limb.Results:All the 10 patients received the follow-up for 6 to 12 months, with an average of 8.5 months. The donor and recipient flaps survived completely with good appearance in lower limb, good soft texture, good elasticity and wear resistance. The sensation of the flap with nerve anastomosis in 3 cases was evaluated according to BMRC, and they achieved sensation recovery up to level of S 3 or above. The patients had great satisfactions. At the last follow-up, the curative efficacy was evaluated according to the Maryland scoring system. It ranged from 85 to 98 points, with an average of 91.6 point, 8 patients in excellent and 2 in good. Conclusion:Sural neurouascular flap can achieve a sufficient blood supply, a reasonable venous circulation and a high survival rate. The donor site was covered with relay flap to obtain a good appearance, and the anastomosed sensory nerve offered a good sensation. The function of foot and ankle recovered well, and the clinical effect was satisfactory.
