OBJECTIVE To explore the effect and underlying mechanism of promethazine(PMZ) on proarrhythmia in guinea pigs. METHODS ① InvivoECG recordings were made to analyze effects of jugular intravenous(iv)injection of PMZ on ECG in guinea pigs. PMZ was injected in this order:3.83→7.67→15.33→38.33 mg·kg-1 cumulatively. ② In vitroECG recordings were made to analyze effects of PMZ on ECG in isolated hearts of guinea pigs. PMZ was perfused in such order:0. 1 → 1 → 10 →50 μmol·L-1 . ③ L-type Ca2+ currents from ventricular myocytes in guinea pigs were recorded to investi-gate the PMZ's blocking effect. PMZ was perfused in such order:0.1→1→10→50 μmol·L-1→washout.④ hNav1.5 and hERG currents were recorded to investigate the PMZ's blocking effects. PMZ-perfused in such order:1→3→10→30 μmol·L-1 for hNav1.5 current analysis,and 0.3→1→3→10 μmol·L-1 for hERG current analysis. RESULTS ① PMZ(15.33 mg·kg-1 )significantly prolonged QRS intervals in guinea pigs invivoECG(P﹤0.05). PMZ(38.33 mg·kg-1 )prolonged QRS,QTc,and P-R intervals but reduced the heart rate( P﹤0.05). PMZ(10 μmol·L-1 )reduced the heart rate of isolated guinea pig hearts. PMZ 50 μmol·L-1 prolonged QRS and QTc intervals and further reduced the heart rate(P﹤0.05).③ PMZ inhibited the L-type Ca2+ current from ventricular myocytes in guinea pigs in a concentration-dependent manner with the lC50 of(8.9±1.0)μmol·L-1 . ④ PMZ inhibited the hNav1.5 and hERG currents in a concentration-dependent manner with the lC50 of 6.1±1.5 and(1.6±0.2)μmol·L-1 ,respectively. CONCLUSION PMZ might cause arrhythmia at overdoses and incombination with other drugs which have potential blocking effect on /Na ,Ca2+ and /kr currents. The proarrhythmic effect of PMZ might be mediated by the blocking effect on /Na ,Ca2+ and /kr currents.

OBJECTIVETo investigate the effect of berberine on serum levels of TNF-alpha, IL-6 and adiponectin in obese mice induced by high fat diet and its potential molecular mechanisms.
METHODNormal male Kunming mice were randomly divided into two groups taking normal chow (NC, n = 10) and high fat diet (HF, n = 30), respectively. After 13 weeks, HF mice were continuously given high fat diet and divided into three groups, model group (BM), low-dosage of berberine group (BL) and high-dosage of berberine group (BH). Mice in BL and BH were administered berberine by gavage at the dosage of 50 mg x kg(-1) and 150 mg x kg(-1), respectively. Two weeks later, oral glucose tolerance test was performed. At the end of the experiment, the mice were killed and blood samples were collected. The epididymal fat tissue and liver were removed promptly and weighed. The serum cytokine was measured by ELISA. The levels of IkappaB kinase beta (IKK-beta) and IKK-beta (ser181) were detected by Western blotting.
RESULTSerum levels of TNF-alpha, IL-6 in mice of BM were significantly higher than those in NC (P < 0.05). After two-week treatment of berberine, serum levels of TNF-alpha, IL-6 in BL and BH were lower than those in BM (P < 0.05, respectively). However, there were no significant difference of adiponectin among four groups. The degrees of phosphorylation of IKK-beta (ser181) were decreased in liver and adipose tissue in BH in comparison to that in BM, although the expression of total IKK-beta did not change. Furthermore, the glucose tolerance was improved, while the body weight and epididymal fat were reduced in mice treated with berebrine. 9: Berberine is able to reduce inflammatory cytokines expression and inhibit activation of IKK-beta (ser181) in obese mice, which may partly explain the therapeutic effect of berberine on insulin resistance and abnormal glucose metabolism.

Objective:To establish a disease risk prediction model for the newborn screening system of inherited metabolic diseases by artificial intelligence technology.Methods:This was a retrospectively study. Newborn screening data ( n=5 907 547) from February 2010 to May 2019 from 31 hospitals in China and verified data ( n=3 028) from 34 hospitals of the same period were collected to establish the artificial intelligence model for the prediction of inherited metabolic diseases in neonates. The validity of the artificial intelligence disease risk prediction model was verified by 360 814 newborns ' screening data from January 2018 to September 2018 through a single-blind experiment. The effectiveness of the artificial intelligence disease risk prediction model was verified by comparing the detection rate of clinically confirmed cases, the positive rate of initial screening and the positive predictive value between the clinicians and the artificial intelligence prediction model of inherited metabolic diseases. Results:A total of 3 665 697 newborns ' screening data were collected including 3 019 cases ' positive data to establish the 16 artificial intelligence models for 32 inherited metabolic diseases. The single-blind experiment ( n=360 814) showed that 45 clinically diagnosed infants were detected by both artificial intelligence model and clinicians. A total of 2 684 cases were positive in tandem mass spectrometry screening and 1 694 cases were with high risk in artificial intelligence prediction model of inherited metabolic diseases, with the positive rates of tandem 0.74% (2 684/360 814)and 0.46% (1 694/360 814), respectively. Compared to clinicians, the positive rate of newborns was reduced by 36.89% (990/2 684) after the application of the artificial intelligence model, and the positive predictive values of clinicians and artificial intelligence prediction model of inherited metabolic diseases were 1.68% (45/2 684) and 2.66% (45/1 694) respectively. Conclusion:An accurate, fast, and the lower false positive rate auxiliary diagnosis system for neonatal inherited metabolic diseases by artificial intelligence technology has been established, which may have an important clinical value.
