Objective To investigate the reference interval of platelet‐related parameters including mean platelet volume (MPV) ,platelet distribution width (PDW) ,platelet hematocrit (PCT) .Methods Used Sysmex XN‐9000 assembly line and PEN‐TRA 120 hematology analyzer to analysis the venous blood cells for 3 415 cases of 16 to 90 years old physical examination personnel in Mianyang Central Hospital ,the platelet‐related parameters results of 2 718 standard healthy population by screening were statis‐tically analyzed .Results Platelet‐related parameters 95% reference interval (2 .5% -97 .5% ) of XN assembly line :M PV 9 .9-14 . 7 fL ,PDW 11 .2% -24 .3% ,PCT 0 .15% -0 .30% ;Platelet‐related parameters of 95% reference interval of PENTRA 120:MPV 8 .4-12 .7 fL ,PDW 13 .8% -24 .8% ,PCT 0 .12% -0 .26% ;comparison between the instruments :MPV ,PDW ,PCT results showed significant differences (P<0 .05);comparison between men and women :PCT test results of XN assembly line were differ‐ent (P<0 .05) ,MPV ,PDW ,PCT results of PENTRA 120 were different (P<0 .05);comparison between age groups :PCT result of all ages between men and women were different in XN assembly line (P<0 .05) ,in PENTRA 120 ,MPV ,PDW ,PCT results be‐tween ages were different in men (P<0 .05) ,PCT results between ages were different in women (P<0 .05) .Conclusion Each la‐boratory should establish the laboratory supporting biological reference interval of platelet‐related parameters based on different in‐struments ;in practical applications ,should set the reference interval for different gender or age .

To investigate the chemical constituents of the aerial part of Piper wallichii. Nine compounds were isolated by various chromatographic techniques and the structures were elucidated by their physicochemical properties and the spectral data analysis. Nine compounds were identified as one lignan (-)-galbelgin (1) and eight neolignans: denudatin B (2), hancinone D (3), (+)-licarin A (4), kadsurenone (5), wallichinine (6), hancinone C (7), hancinone B (8), (+)-burchellin (9). Compounds 1, 3, 4, 8, 9 were isolated from this plant for the first time.

Since the enrollment in 2002, the cultivation model of "4+4" program of clinical medicine in Shanghai Jiao Tong University School of Medicine has been continuously explored and practiced. With the goal of cultivating high-level compound outstanding medical innovative talents with multi-disciplinary cross-capacity, through strengthening the heuristic teaching, establishing the medical-engineering cross-course, emphasizing the training of scientific research ability, and taking teaching reform in the basic clinical single-circulation organ system integration course, we have established a talent training system with the characteristics of Shanghai Jiao Tong University School of Medicine, which is characterized by "thick foundation, strong practice, re-transformation, shaping norms, and international integration", and intend to make further exploration in the field of post-graduation education convergence.

【Objective】 To understand the current situation of blood components distribution in domestic prefecture-level blood stations through analyzing the components distribution data of 24 prefecture-level blood stations in China. 【Methods】 The data of components distribution of 24 blood stations from 2017 to 2020 as well as the data of blood deployment of 24 blood stations from 2019 to 2020 were collected and analyzed. 【Results】 From 2017 to 2020, positive annual growth in red blood cells, plasma and cryoprecipitate was observed in 22, 19 and 15 out of the 24 blood stations, and the annual growth median rate of above three components was 5.24%, 3.80% and 3.25%, respectively. Among the 24 prefecture-level blood stations, 23 carried out the preparation of cryoprecipitate. 【Conclusion】 The distribution of red blood cells, cryoprecipitate and plasma in prefecture-level blood stations is increasing year by year. However, there is a overstock of plasma, and most blood stations need blood employment.
