ABSTRACT
Objective@#To compare and analyze patient’s general condition, changes in laboratory parameters, and the spectrum of UGT1A1 mutations in patients with inherited non-hemolytic unconjugated hyperbilirubinemia.@*Methods@#A retrospective study was conducted at Nanjing Second Hospital from January 2015 to July 2018 and patients’ demographic characteristics, liver function test, and UGT1A1 gene were analyzed. The categorical variable data were compared by χ 2 test. The normal distribution continuous variable data were compared by t-test and the non-normal distribution continuous variable data were compared using Mann-Whitney U test.@*Results@#Of the 51 patients with inherited non-hemolytic unconjugated hyperbilirubinemia, 44 (86.3%) were Gilbert’s syndrome (GS) and seven (13.7%) were Crigler-Najjar syndrome type II (CNS- II). The male to female ratio was 2.9:1 and the average age was 36.11 ± 13.17 years. Six variant types were detected: C. -40_-39insTA, C. -3279T > G, c.211G > A (p.G71R), c.686C > A (p.P229Q), c.1091C > T (p.P364L), c.1456T > G (P.Y486D). Among them, c.211G > A accounted for 58.82% (30/51), c.-40_-39insTA accounted for 27.5% (14/51), and c.1456T > G accounted for 25.5% (13/51). The total bilirubin(TB) and unconjugated bilirubin (UCB) in CNS-II patients were significantly higher than GS patients[155.91 (130 ~ 207) vs. 38.25(29 ~ 52.15) μmol/L, U = 0, P < 0.01; 144.13 (120.8 ~ 197) vs. 30.00 (21.7 ~ 46.75) μmol/L, U = 0.00, P < 0.01, respectively]. Exon mutations of c.1091C > T and c.1456T > G were statistically significant(P < 0.01).There were no differences in age, TB, UCB, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) between the c.211G > A homozygous variants and heterozygous variants (P > 0.05).@*Conclusion@#The common pathogenic mutations of UGT1A1 gene were c.211G > A, c.-40_-39insTA, c.1456T > G. c.211G > A. The mutation has little effect on the level of total bilirubin, but c.1091C > T, c.1456T > G mutations has great influence on the level of total bilirubin.
ABSTRACT
Objective: To observe the changes of heart rate and the contents of angiotensin Ⅱ(AngⅡ) in blood plasma in ventricular tachycardia(VT) rats with electro-acupuncture(EA) on ‘daling’(PC7). Methods: 40 SD rats were randomly divided into normal, model, treatment and control groups with 10 cases in each. VT model was duplicated by inject CsCl in femoral vein. To observe the rats’ electrocardiogram (ECG) and record their heart rates. EA was applied to‘daling’ (PC7) on treatment group and applied to‘Taiyuan’ (LU9) on control group for 5 minutes. Then, we detected the contents of AngⅡ in the rats’blood plasma respectively. Results: The heart rate and contents of AngⅡin rat increased obviously in model group were (547?30) time/min and (353.21?49.12)pg/mL). They restored to the normal state after EA ‘daling’ (PC7) are(474?25)time/min and(268.44?47.49)pg/ mL.But the effect was not obvious in ‘Taiyuan’ (LU9). Conclusion VT rat heart can be prompted to restore to the normal state after EA ‘daling’(PC7); AngⅡ played an important role in VT.
ABSTRACT
Objective To study the function of ventrolateral medulla (VLM) in the treatment of rabbit myocardial ischemia by electroacupuncture at Neiguan point. Methods On the basis of the protection of rabbits against acute myocardial ischemia by electroacupuncture at Neiguan point,the action potential of rabbit's ischemic myocardial cell was observed after the VLM was blocked with Naloxone. Results Compared with the sham operation group, acute myocardial ischemia group and sham VLM block group,the ST segment potential remarkably increased and MAPA, MAPD_~50 ,MAPD_~90 significantly decreased in VLM block group. There were statistic significance(P
ABSTRACT
Objective To observe whether electroacupuncture (EA) is protective to the blood-brain barrier (BBB) in rabbits with acute cerebral infarction and explore the underlying mechanisms. Methods Eighty rabbits were used in this study. After establishing the acute cerebral infarction rabbit model,all the animals were randomly allocated to a model group and an EA group. The acupoint "Bai Hui" and "Shui Gou" in Du meridian in the rabbits of the experimental group were stimulated by EA. The content of ANP,cAMP and cGMP was examined. Results Compared with the model group,the content of ANP in blood plasma and cAMP in brain tissue of the EA group significantly increased,while the content of cGMP decreased,the ratio cAMP/cGMP increased nearly to the normal level. Conclusion The EA exerted protective effect and promoted repair of BBB in rabbits with acute cerebral infarction,which might be modulated by the changes of the content of ANP in blood plasma and cAMP,cGMP in brain tissue.
