Objective To detect the relationship between the polymorphism of the glycogen-targeting regulatory subunit of the skeletal muscle glycogen-associated protein phosphatase 1 (PPP1R3) gene and type 2 diabetes by case-control study. Methods We genotyped the PPP1R3 gene Asp905Tyr polymorphism and a common 3'-untranslated region AT (AU)-rich element (ARE) polymorphism in 101 type 2 diabetic patients and 101controls by oligonucleotide ligation assay (OLA) and polyacrylamide gel elecrophoresis, respectively. Results Subjects with Tyr/Tyr genotypes whose body mass index (BMI)<25 were used as the reference group. Those whose BMI25 with Asp905 had a 3.66-fold increase (95% CI: 1.48-9.06, P=0.005) in type 2 diabetes risk. No association was found between 3'UTR ARE polymorphism and type 2 diabetes mellitus (OR=1.15; 95% CI: 0.62-2.14, P=0.65). Conclusion A joint effect between the Asp905 and BMI increases the risk of type 2 diabetes, and Asp905Tyr and ARE polymorphism of PPP1R3 gene are not the major diabetogenic gene variants in Chinese population.

OBJECTIVETo determine the relationships of Met416Val and XbaI polymorphism of muscle glycogen synthase (GYS1) gene and Trg64Arg variant of the beta(3)-adrenergic-receptor (beta(3)-AR) gene with type 2 diabetes mellitus (DM) and its intermediate phenotypes in the Chinese population.

METHODSPolymerase chain reaction-oligonucleotide ligation assay and restriction fragment length polymorphism assay were used to evaluate the GYS1 and beta(3)-AR gene polymorphisms in 102 pairs of case-control Chinese spouses.

RESULTSSubjects with Met416Val variant had a significantly higher 2-hour post-glucose level than subjects without this variant had in diabetic group (P = 0.032). The Met416Val polymorphism of GYS1 gene was not significantly associated with the risk of type 2 DM (adjusted OR = 1.67; 95% CI: 0.73 - 3.81, P = 0.223). Subjects with Trp64Arg variant had a significantly higher serum uric acid level than subjects without this variant had in diabetic group (P = 0.034). The combination of BMI and Arg64 allele carrier of the beta(3)-AR gene increased the diabetic risk over four-fold (adjusted OR = 4.00; 95% CI: 1.53 - 10.45, P = 0.005).

CONCLUSIONSIn the Chinese population, Met416Val polymorphism is identified in a subgroup of diabetic subjects with high 2-hour post-glucose. It will explain why some diabetic patients appear to be genetically predisposed to developing high postpradial glucose level. The presence of the Arg64 allele in the beta(3)-AR gene may predispose patients to higher serum uric acid level.

Objective:To explore the diagnostic efficacy of ultrasonography and follow-up outcomes of hepatic venous outflow obstruction after liver transplantation(LT)in children.Methods:From July 2017 to January 2022, 32 children diagnosed with outflow tract obstruction post-LT are designated as HVOO group and examined by digital subtraction angiography(DSA).All of them underwent balloon dilation.Thirty cases with no vascular complications are selected as control group.Color Doppler blood flow parameters are recorded, including peak systolic velocity(PSV), peak diastolic velocity(PDV), PSV/PDV(S/D), resistive index(RI), portal vein velocity(PVV), hepatic vein velocity(HVV), hepatic vein waveform, anastomotic velocity and waveform.Intravascular pressure values of DSA within 48h are recorded.The correlations between color Doppler flow parameters and intravascular pressure values are examined before and after tube expansion.The differences of color Doppler flow parameters before tube expansion between HVOO and control groups are compared.And receiver operating characteristic(ROC)curves are plotted for obtaining ultrasonic parameters' cut-off value.Patients with excellent recovery are selected for comparing the difference of color Doppler blood flow parameters before and after tube expansion and detect the trend of hemodynamics.Results:There is a positive correlation between anastomotic velocity of hepatic vein and inferior vena cava and DSA before and after tube expansion in HVOO group(r=0.483, 0.414, all P<0.05); S/D, RI and anastomotic velocity are higher in HVOO group than those in control group( Z=-3.275, P=0.001; t=3.437, P=0.001; Z=-5.677, P<0.01); PV and HVV are lower in HVOO group than those in control group( Z=-2.719, P=0.007; Z=-6.762, P<0.01); The waveforms of hepatic vein and anastomosis in HVOO group are mostly single-phase waves, accounting for 81.25%(26/32)and 53.12%(17/32).Control group is mostly of dual-phase wave.According to ROC curve analysis, area under curve(AUC)of HVV diagnosing HVOO is 0.996 with a critical value of 21.65 cm/s; AUC of hepatic vein anastomosis velocity is 0.92 with a critical value 162 cm/s and AUC of RI 0.76 with a critical value of 0.73.PVV and HVV values after tube expansion are higher than before tube expansion( Z=-2.233, P=0.026; Z=-4.45, P<0.01); Anastomotic velocity after tube expansion is lower than that before tube expansion( t=8.584, P<0.01).The waveforms of hepatic vein and anastomosis are mostly of single-phase waves(76.92%, 61.54%)before tube expansion and dual-phase wave(88.46%, 96.15%)after tube expansion. Conclusions:Color Doppler ultrasound is a preferred imaging modality for diagnosing HVOO and conducting postoperative follow-ups in children after LT because of its non-invasiveness, real-time, simplicity and rapidness.Furthermore, the diagnostic efficiencies of hepatic vein and anastomotic velocity are relatively high.

Objective:To obtain the normal reference range of ultrasound hemodynamic parameters after liver transplantation through big data query and statistical analysis, and to analyze its influencing factors.Methods:The clinical liver transplantation Ultrasound Image Database Software V1.0 developed by Tianjin First Center Hospital was used to query adult patients after liver transplantation from December 2012 to June 2021. The ultrasonic hemodynamic parameters including the diameter of portal vein (PVD), the flow velocity of portal vein (PVV), the peak flow velocity of hepatic artery (S), the end diastolic flow velocity of hepatic artery (D), the S/D of hepatic artery, the resistance index of hepatic artery (RI), the diameter of middle hepatic vein (MHVD), the flow velocity of middle hepatic vein (MHVV), the diameter of right hepatic vein (RHVD), the flow velocity of right hepatic vein (RHVV), in the first day (1D), the seventh day (7D), the first month (1M), the sixth month (6M), the first year (1Y), the fifth year (5Y) and the tenth year (10Y) after operation were analyzed statistically, and the 95% reference value range of each parameter was obtained.Results:A total of 1 740 patients with 12 242 monitoring results after adult liver transplantation were included, and the longest follow-up time was 22 years. There was no significant change in PVD. PVV decreased slightly from postoperative 1D to long-term follow-up. The S and D of hepatic artery were the highest in group 7D after liver transplantation, and then decreased gradually with the extension of postoperative time. Hepatic artery S/D was the lowest in group 7D after operation, with the extension of monitoring time after liver transplantation, it showed an upward trend, but fluctuated. Hepatic artery RI was the highest in postoperative 1D group, and fluctuated with the extension of monitoring time after liver transplantation. There was no significant change in MHVD and RHVD.MHVV and RHVV were the highest in group 7D after liver transplantation, with the extension of postoperative monitoring time, they showed a decreasing trend and fluctuated. The normal range of each parameter was estimated according to the range of 95% medical reference value. The influencing factors of blood flow monitoring of transplanted liver were analyzed, including the various factors in perioperative period, the surgery, the primary disease before operation, the source of donor, the postoperative infection, rejection, drug damage, individual differences and so on.Conclusions:This study obtains the trend of each parameter with the extension of follow-up time and the reference value range of each parameter after liver transplantation, which is of great clinical significance for early detection and diagnosis of postoperative vascular complications. However, the blood flow after adult liver transplantation is affected by many factors. In clinical monitoring, it is necessary to make judgment combined with the individual state of patients and conduct dynamic follow-up.
