Abstract: Objective　To investigate the early diagnostic value of peripheral blood procalcitonin (PCT), C-reactive protein (CRP), fibrinogen (FIB) and D-dimer (D-D) levels in patients with pulmonary tuberculosis (PTB) complicated with bacterial pneumonia. Methods　A total of 102 patients who admitted to Department of Tuberculosis of Affiliated Nantong Hospital of Shanghai University from Jan 2021 to May 2022 were enrolled in this study and divided into a group (52 cases) with pulmonary tuberculosis (PTB) patients and a group (50 cases) with PTB patients complicated with bacterial pneumonia. The levels of PCT, CRP, FIB and D-D in the peripheral blood were measured, the differences and correlations in all indicators were compared among two groups. The sensitivity and specificity of these indicators in the early diagnosis of PTB complicated with bacterial pneumonia were analyzed by receiver operating characteristic (ROC) curve. Results　The levels of PCT, CRP, FIB and D-D in the peripheral blood from the PTB complicated with bacterial pneumonia group were 0.06 (0.04, 0.16) ng/mL, 38.00 (3.88, 96.10) mg/L, 4.51 (3.02, 6.07) g/L, and 0.59 (0.34, 1.88) mg/L, respectively, which were significantly higher than corresponding 0.04 (0.03, 0.04) ng/mL, 3.20 (0.84, 7.22) mg/L, 2.96 (2.48, 3.77) g/L, and 0.27 (0.17, 0.36) mg/L in the PTB group (Z=-4.784, -5.233, -3.853, -4.199, all P<0.001). Furthermore, the levels of CRP and FIB in the PTB complicated by bacterial pneumonia group were highly positively correlated (r=0.855, P<0.001). The area under the ROC curve (AUC) of PCT, CRP, FIB and D-D for early diagnosis of PTB complicated with bacterial pneumonia were 0.757, 0.794, 0.747 and 0.764, respectively. In addition, the AUC obtained by simultaneous measurement of PCT, CRP, FIB and D-D was as high as 0.916, and the sensitivity and specificity of diagnosing PTB complicated with bacterial pneumonia were increased to 85.7% and 96.9%, respectively, which were higher than those of individual indicators. Conclusions　Levels of peripheral blood PCT, CRP, FIB, and D-D all show varying degrees of increase in patients with PTB complicated with bacterial pneumonia, and detecting the levels of all four markers, rather than any single marker, can assist in early monitoring whether the tuberculosis patients are complicated with bacterial pneumonia.

Breviscapine, a flavone glucuronide, is a cardiovascular medicine extracted from a Chinese herb Erigeron breviscapinus. Modern pharmacological research shows breviscapine has a therapeutic effect on cardiovascular diseases such as cerebral thrombus,cerebral ischemia hemiparesis and platelet aggregation et al. However, its poor water solubility and low bioavailability in vivo severely restrict the clinical application. In this article, we reviewed the marketing preparations of breviscapine and its research progress on the new dosage forms.

OBJECTIVETo achieve the quality control of Herba Epimedii, and to evaluate the quality of medical materials of the 8 official species including the 5 species recorded in 'Chinese Pharmacopoeia' including Epimedium brevicornum, E. sagittatum, E. pubescens, E. koreanum and E. wushanense, and the 3 other species (E. acuminatum, E. myrianthum, E. leptorrhizum) recorded in 'Guizhou Quality Criteria for Traditional Chinese Medical Material and Nationality Medical Material', and E. pseudowushanuse (new species) which is used as E. wushanense for a long time.

METHODThe contents of icariin and total flavonoids of 102 samples of 9 officinal species of Herba Epimedii were determined by HPLC and UV, respectively.

RESULT AND CONCLUSIONThe contents of icariin in about 30% of the samples of the 5 species recorded in 'Chinese Pharmacopoeia' were lower than 0.5%, which is acceptable quality recorded in 'Chinese Pharmacopoeia'. Refering the literatures, we suggested the total contents of epimedin A, B, C and icariin (epi-medium multi-glycosides, ABCI) should be established as a new standard instead of the content of icariin. The content of total flavonoids, not less than 5.0%, and ABCI, not less than 1.3%, could be used to evaluate the quality of the above medical materials efficiently.
