The tools used for the literature quality evaluation are introduced. The common evaluation tools that are publicly and extensively used for the evaluation of clinical trial literature quality in the world are analyzed, including Jadad scale, Consolidated Standards of Reporting Trials (CONSORT) statement and Grades of Recommendations Assessment, Development and Evaluation (GRADE) system and the others. Additionally, the present development, updates and applications of these tools are involved in analysis.

OBJECTIVETo investigate the optimal time and method of the early repair of the full layer eyelid defect caused by chemical burn.

METHODSFree nasal septum mucosal cartilage flap with muscle flap, skin grafting, or skin flap were performed in 18 cases (19 eyelids) with chemical burn within 4 postburn weeks. Eyelid reconstruction and corneal transplantation were performed at the same time in 4 patients.

RESULTSAll the reconstructed eyelids and transplanted cornea survived. The incidence of severe complications, such as exposure keratitis, corneal ulcer and eyeball perforation decreased.

CONCLUSIONFull layer eyelid defect caused by chemical burn should receive early reconstruction and repair, including timely reconstruction of eyelid for the sake of protecting the eyesight and of alleviating the inflammatory reactions, and the corneal transplantation should be done at the same time to avoid corneal perforation. Nasal septum mucosal cartilage flap could be ideal for the eyelid reconstruction.

OBJECTIVETo analyze the karyotype stability in hematological malignancies patients before and after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and its prognostic significance of monitoring.

METHODSThe karyotypes and clinical data of 21 patients with hematological malignancies at the initial diagnosis and at relapse after allo-HSCT were retrospectively reviewed. Chromosome analysis was performed by standard 24 h-cultured method and R banding.

RESULTSKaryotypes at the initial diagnosis and at relapse after allo-HSCT were different in 11 patients (52.38%), including chromosome 1, 3, 6, 12, 17, 21. Numberical abnormalities and structural chromosomal abnormalities always occurs together. The median survival time of relapse of the patients with karyotype changes was significantly shorter than that of patients without a karyotype change (79 d vs 522 d, P = 0.027), and that of the patients with trisomy 6 was also significantly shorter than that of the patients without trisomy 6 (9 d vs 275 d, P = 0.005).

CONCLUSIONKaryotype changes after relapse are associated with the prognosis of allo-HSCT.

This study aims to explore the consistency between macroscopic identification and DNA barcoding identification of Amomi Fructus. With the DNA barcoding identification results, we evaluated the reliability of identifying Amomi Fructus quality by combining macroscopic traits with main volatile chemical components. Thirteen batches of Amomi Fructus samples were collected for identification. Firstly, the morphological and sensory characteristics of each sample were observed and recorded according to the standard in Chinese Pharmacopoeia(2020 edition). The 100-fruit weight, longitudinal diameter, transverse diameter, and longitudinal diameter-to-transverse diameter ratio were measured, which correspond to large, solid, and full kernel representing good quality in the sensory evaluation. The odor value detected by electronic nose and major volatile components(borneol, camphor, limonene, and borneol acetate) correspond to the sensory evaluation of strong odor representing good quality. Secondly, DNA barcoding was employed to identify the 13 batches of samples. Finally, clustering analysis was performed for the main volatile components and macroscopic traits, and the identification results were compared with those of DNA barcoding. Except two batches of samples(No.6 and No.10), the macroscopic identification showed the results consistent with those of DNA barcoding, with an identification rate of 84.62%. The clustering results of the content of four volatile chemical components and macroscopic traits were also consistent with the DNA barcoding identification results. DNA barcoding can verify the results of macroscopic identification and provide a scientific basis for the inheritance and development of macroscopic identification. Moreover, the combination of macroscopic traits and chemical components demonstrates higher accuracy in the quality evaluation of Chinese medicinal materials.

A spectrum-activity relationship is established with high performance liquid chromatography(HPLC) fingerprints and the in vitro antioxidant activity to improve the quality evaluation system of Aralia taibaiensis. The HPLC profiles of 12 batches of samples were collected, and the similarity evaluation, heat map analysis and principal component analysis were conducted for the chemometric study of the fingerprint data. Combined with grey correlation analysis, the contributions of the common peaks in the fingerprints to the antioxidant activity were clarified, and the important peaks reflecting the efficacy were identified. The results showed that 17 common peaks were found in 12 batches of A. taibaiensis samples, and 6 of them were identified as saponins. Similarity evaluation, heat map analysis and principal component analysis roughly classified the A. taibaiensis herbs into two categories, i.e.,(1) S1-S10, S12 and(2) S11. Twelve batches of samples showed different antioxidant activities in a dose-dependent manner. In particular, S9 had the strongest antioxidant activity, while S11 was the weakest in antioxidant capacity, which was basically consistent with the overall score results. The results of grey correlation analysis demonstrated that the 17 common peaks scavenged DPPH radicals in the following order: X_3>X_(17)>X_4>X_8>X_7>X_(13)>X_2>X_6>X_(11)>X_(10)>X_(16)>X_(12)>X_9>X_5>X_(14)>X_1>X_(15), and scavenged ABTS radicals in the order of X_4>X_3>X_7>X_8>X_2>X_(17)>X_(13)>X_6>X_(16)>X_(11)>X_5>X_(12)>X_(10)>X_9>X_(14)>X_1>X_(15). Among them, X_3, X_4, X_7(araloside C), X_8 and X_(17) were the important peaks reflecting the efficacy of A. taibaiensis, which were basically consistent with those contained in the principal component 1. In this study, the correlation between the HPLC fingerprints of 12 batches of A. taibaiensis and its antioxidant activity provides a reference for the Q-marker screening and quality control of A. taibaiensis.
