Objective:To study the role of myocardial work parameters in early identification of myocardial injury in neonatal asphyxia.Methods:From July 2020 to December 2021, neonates diagnosed with mild neonatal asphyxia admitted to the Department of Neonatology of our hospital within 24 h after birth were prospectively enrolled into the asphyxia group. Neonates without asphyxia during the same period were selected as the control group and matched with the asphyxia group for gender, gestational age and birth weight at a ratio of 1:1~1:2. The asphyxia group was subgrouped into preterm asphyxia group and term asphyxia group. All neonates received echocardiography within 24 h after birth. Multiple parameters were measured including M-mode, two-dimensional image, Doppler image, global longitudinal strain (GLS) and myocardial work parameters [global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE)]. The level of serum N-terminal pro brain natriuretic peptide (NT-proBNP) was recorded in the asphyxia group. The data were compared between the asphyxia group and the control group. Correlations between myocardial work parameters and other parameters were analyzed.Results:A total of 33 cases were in the asphyxia group and 43 cases were in the control group. The preterm asphyxia group (18 cases) showed significantly lower GWI and GCW than the preterm control group (18 cases) [GWI: (702±153) mmHg vs. (879±205) mmHg, GCW: (1 016±221) mmHg vs. (1 200±271) mmHg] ( P<0.05). No differences existed in GLS, GWW and GWE. The term asphyxia group (15 cases) showed significantly lower GWW than the term control group (25 cases) [45.0 (30.0, 65.0) mmHg vs. 71.0 (35.5,85.5) mmHg] ( P<0.05). No differences existed in GLS, GWI, GCW and GWE. GWI was negatively correlated with serum NT-proBNP level ( r=-0.327, P<0.05). Conclusions:GWI and GCW may indicate myocardial injury in preterm neonates with mild asphyxia.

Purpose To use two-dimensional speckle tracking imaging(2D-STI)to evaluate left ventricular myocardial strain in term and preterm neonates.Materials and Methods A total of 81 neonates who accepted echocardiography in Soochow University Affiliated Children's Hospital from February to August 2018 were retrospectively enrolled,including 42 term neonates and 39 preterm neonates.Longitudinal and circumferential peak strain of each segment of left ventricle were measured by 2D-STI,and the average global longitudinal peak strain(GLPS-avg)and the average global circumferential peak strain(GCPS-avg)of left ventricular were measured too.Left ventricular ejection fraction(LVEF-M,LVEF-Simpson),short-axis shortening rate(LVFS-M),left ventricular end-diastolic diameter(LVEDD),and tissue Doppler imaging parameters(E',A' and E'/A')of the septal mitral annulus were also measured.The differences in each segment of left ventricle and echocardiography between term neonates and preterm neonate were further compared.Results There were statistically significant differences in GLPS-avg,the global longitudinal peak strain from the apical two-chamber view(GLPS-a2c),GCPS-avg and the global circumferential peak strain in the middle and apical segments(GCPS-M ang GCPS-A)(t=-3.60--2.18,all P<0.05)between term neonates and preterm neonates,while there were no significant differences between the global longitudinal peak strain from the apical four-chamber and three-chamber view(GLPS-a4c and GLPS-a3c),the global circumferential peak strain in the basal segments(GCPS-M)(all P>0.05).There were statistically significant differences in GLPS-a4c,GLPS-a2c,GLPS-a3c in preterm neonates group(F=3.20,P=0.044),and the strain value GLPS-a4c was the highest.There were statistically significant differences in GCPS-B,GCPS-M,GCPS-A in preterm neonates group(F=79.15,P<0.001).There were statistically significant differences in GCPS-B,GCPS-M,GCPS-A in term neonates group(F=97.95,P<0.001),and the strain value increased from the basal segment to the apical segments.There was statistically significant difference in LVEDD between term neonates and preterm neonates(all P<0.05).There were no statistically significant differences in LVEF-M,LVEF-Simpson,LVFS-M,E',A' and E'/A' between term neonates and preterm neonates(all P>0.05).Conclusion 2D-STI may be a useful method of measuring left ventricular myocardial systolic function and can provide early detection of differences in left ventricular myocardial contraction between term and preterm neonates.

Objective:To observe the clinical effect of scraping therapy on lumbar disc herniation (LDH) with different syndromes.Methods:Using the convenient sampling method, a total of 30 non-emergency LDH patients who were admitted to Department of Orthopedics and Traumatology of Yangzhou Hospital of Traditional Chinese Medicine from July 2017 to June 2018 were selected as the research objects. Among them, there were 11 cases of qi stagnation and blood stasis syndrome, 8 cases of damp-heat obstruction syndrome, 7 cases of cold-damp obstruction syndrome and 4 cases of liver and kidney deficiency syndrome. Du meridian, the bladder meridian of Foot Taiyang, as well as Jiaji (EX-B2) in pathological or painful sections, Ashi point, Shenshu (BL 23) , and Weizhong (BL 40) were mainly scraped. The treatment interval is 2~5 days (the marks of scrapping fade) , twice of scrapping as a treatment course and a total of 3 courses involved in the whole treatment. Japanese Orthopaedic Association (JOA) Score, Visual Analogue Scale (VAS) , serum interleukin-1 β (IL-1β) and interleukin-10 (IL-10) were compared before and after scraping.Results:Compared with those before scraping, the JOA score increased, the VAS decreased, the serum IL-1β content decreased and the serum IL-10 content increased after scraping, and the differences were sttaistically significant ( P<0.01) . Among them, the JOA scores of patients with qi stagnation and blood stasis syndrome and cold-damp obstruction syndrome were higher than those of damp-heat obstruction syndrome and liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . The levels of serum IL-10 in patients with qi stagnation and blood stasis syndrome, damp-heat obstruction syndrome and cold-damp obstruction syndrome were higher than those in patients with liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . Conclusions:The curative effect of scraping in the treatment of LDH is definite, and the curative effect is better for excessive syndromes.

The existing researches on scraping mostly focus on the observation of curative effect and preliminary attempts to explore the mechanism of action, but the research on scraping manifestation is slightly insufficient. At present, scraping manifestation studies mainly include skin appearance, skin blood perfusion, and skin temperature. These studies have laid the foundation and provided a reference for the standardization, normalization, and visualization research of scraping technology in the future. However, these studies are still in their infancy and need to be further studied.
