ABSTRACT

Gestational diabetes mellitus (GDM) is a serious threat to maternal and infant health. However, the unclear etiology and pathogenesis of GDM is the harrier of clinical intervention. In recent years, the relationship between inflammation and GDM has been widely concerned, but the conclusions are inconsistent. This paper summarizes the research progress on the association between inflammation-related indicators and GDM, in order to provide a basis for the diagnosis, treatment, or prophylaxis of GDM.

ABSTRACT

Objective:To investigate the effect of transcatheter arterial chemoembolization (TACE) combined with ultrasound-guided radiofrequency ablation (RFA) on the efficacy and immune function in patients with primary liver cancer.Methods:The clinical data of 152 patients with primary liver cancer from February 2019 to February 2021 in the Second Affiliated Hospital of Xi′an Jiaotong University were retrospectively analyzed. Among them, 76 patients were treated with TACE combined with RFA (combined group), and 76 patients were treated with TACE (control group). The efficacy was compared; the α-L fucosidase, T lymphocyte subsets (CD 3, CD 4, CD 8 and CD 4/CD 8), B lymphocyte subsets (CD 19) and tumor markers (alpha-fetoprotein, AFP; carcinoembryonic antigen, CEA; carbohydrate antigen 125, CA125) before treatment and 1 month after treatment were detected. Results:The total clinical effective rate in combined group was significantly higher than that in control group: 81.58% (62/76) vs. 52.63% (40/76), and there was statistical difference ( χ2 = 4.54, P<0.05). There were no statistical difference in all indexes before treatment between 2 groups ( P>0.05); the α-L fucosidase, AFP and CD 8 1 month after treatment in combined group were significantly lower than those in control group: (18.06 ± 5.33) U/L vs. (26.58 ± 7.75) U/L, (87.93 ± 22.55) μg/L vs. (146.83 ± 21.85) μg/L and 0.295 ± 0.052 vs. 0.367 ± 0.064, the CD 3, CD 4 and CD 4/CD 8 were significantly higher than those in control group (0.489 ± 0.054 vs. 0.462 ± 0.063, 0.363 ± 0.059 vs. 0.303 ± 0.075 and 1.43 ± 0.27 vs. 0.89 ± 0.14), and there were statistical differences ( P<0.01 or<0.05); there was no statistical difference in CEA, CA125 and CD 19 1 month after treatment between 2 groups ( P>0.05). Conclusions:TACE combined with RFA in the treatment of primary liver cancer patients can not only improve the total clinical effective rate, but also significantly improve the immune function, and help to reduce level of the liver tumor marker of AFP.

ABSTRACT

Objective To explore rules of changes in velocity of ultrasound wave transmission at the tibia and radius by a quantitative bone mineral density ultrasound scanner in examination of early incipient rickets in infants and its significance in clinical diagnosis.Methods One hundred and fifty-seven infants who visited child health-care clinic of the Capital Institute of Pediatrics,Beijing during May 2004 to December 2007 and clinically diagnosed as rickets according to the Criteria of Diagnosis for Rickets in Infants and Young Children formulated in 1986 by the Ministry of Health,as well as 124 normal healthy infants as controls,were enrolled in the study and followed-up for three months.Velocity of ultrasound wave transmission at the tibia and radius in all the infants were measured by a bone mineral density ultrasound scanner (Sunlight Omnisense 7000R made in Israel).Results One hundred and fifty-seven infants were clinically diagnosed as rickets,127 of them undergone with carpal plane roentgenography and 90 of the 127 with positive change in bone x-ray imaging and 37 without it.Velocity of ultrasound wave transmission at the tibia and radius measured by z-score was significantly lower in infants with clinically diagnosed rickets than that in healthy controls (Z-values of-10.411 and-10.399 at the tibia and-5.646 and-5.517 at the radius,respectively,P = 0.000 with Mann-Whitney test).Velocity of ultrasound wave transmission at the tibia and radius measured by z-score was lower in those with positive change in x-my imaging than that in those without it,but not reaching a level of statistically significant difference.Velocity of ultrasound wave transmission and z-score correlated positively with change in bone x-ray imaging,respectively with Spearman coefficients of correlation of 0.581 and 0.677 for tibia,0.316 and 0.467 for radius (P = 0.000).Receiver operating characteristic (ROC) curve was drawn from those with rickets and positive left carpal plane roetgenograph.Area under curve of ROC for z-score of velocity of ultrasound wave transmission at the tibia was 0.812 and 0.799 (95% CI 0.758-0.856 and 0.742-0.855,P =0.000),respectively.Area under ROC curve of z-score of velocity of ultrasound wave transmission at the radius was 0.715 and 0.697 (95% CI 0.650-0.780,0.631-0.764,P =0.000),respectively.Cut-off value of z-score was-205--1.95 at the tibia,according to the largest sensitivity and the least false-positivity,with sensibility of 0.8 to 0.9 and specificity of 0.733 to 0.702.As its sensitivity at the radius was more than 0.7,its specificity was lower than 0.524.Conclusions Quantitative ultrasound scanning can be used to detect insufficient bone mineral density in infants and their early skeletal change by rickets but without change in bone x-ray imaging.Velocity of ultrasound wave transmission at the tibia can be used as an indicator to predict early rickets in infants rather than its severity.

ABSTRACT

Based on the analyses of coronary physiology and the principle of fluid mechanics, a Computer Assistant Analysis (CAA) system was built with coronary angiography hardware as well as development of software. With the CAA system,the coronary blood velocity was measured by "Digital Tracing Technique (DTT)" method, and related analysis was performed with Doppler blood the silk (the standard of gold) or TIMI surname blood in 80 cases clinical cases. The results showed a positive correlation (r1 = 0.79, p1 < 0.001) between Vmean (The average blood velocity of LAD, 17.98 +/- 5.66 cm/s) by measurement using digital tracking technique and Average peak velocity (APV:17.70+/-5.77 cm/s) at approximate and distal of LAD by measurement using Doppler wire; and a negative correlation (r=-0.51, P<0.05) with TIMI surname blood (18.58 +/- 6.46 cms/ s vs 28 +/-7.5 frames). The research and clinical application result enunciates: The coronary blood velocity dynamics measured by DTT method is a scientific index applicable to clinical examination for coronary diseases, which would be useful in enhancing the diagnostic ability integrated in anatomy and physiology during conventional angiography.
