Objective:To investigate the effects of continuous substaneous insulin infusion (CSII) on islet β cell function in newly diagnosed diabetic patients.Methods:Forty-six newly diagnosed diabetic patients who received treatment in Taishan People's Hospital from July 2011 to June 2014 were included in this study. They were treated with CSII for 14 days and followed up for 5 years. Before and after treatment, fasting blood glucose (FPG), 2-h postprandial blood glucose (2hPG), triglyceride (TG), fasting insulin (FINS), 2-h postprandial insulin (2hINS), glycosylated hemoglobin (HbA1c), superoxide dismutase (SOD), malondialdehyde (MDA) and the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index, Homeostasis Model Assessment for beta-cell function (HOMA-β) index were compared between before treatment and 5 years after treatment.Results:Five years after treatment, the levels of FPG, 2hPG, TG, HbA1c, MDA and HOMA-IR were lower than those before treatment [FPG: (11.3 ± 1.2) mmol/L vs. (5.9 ± 0.4) mmol/L, t = 15.35, P < 0.01; 2hPG: (18.1 ± 4.2) mmol/L vs. (8.1 ± 1.6) mmol/L, t = 16.83, P < 0.01; TG: (2.9 ± 1.1) mmol/L vs. (1.5 ± 0.6) mmol/L, t = 9.81, P < 0.01; HbA1c: (11.2 ± 2.5)% vs. (5.6 ± 1.0)%, t = 11.48, P < 0.01; MDA: (4.6 ± 1.2) μmol/L vs. (2.7 ± 0.9) μmmol/L, t = 16.37, P < 0.01; HOMA-IR: (2.81 ± 0.35) vs. (1.87 ± 0.32), t = 9.37, P < 0.01]. Five years after treatment, the levels of FINS, 2hINS, SOD and HOMA-β were significantly higher than those before treatment [FINS: (5.6 ± 1.3) mU/L vs. (7.4 ± 1.5) mU/L, t = - 6.15, P < 0.01; 2hINS: (15.8 ± 7.5) mU/L vs. (25.8 ± 9.1) mU/L, t = - 5.65, P < 0.01; SOD: (28.9 ± 7.6) U/L vs. (39.6 ± 7.8) U/L, t = - 7.93, P < 0.01; HOMA-β: (14.36 ± 3.82) vs. (65.67 ± 6.67), t = - 18.72, P < 0.01]. Linear regression analysis showed that HOMA-β was positively correlated with SOD level ( R2 = 0.319, P < 0.01). Five years after treatment, the final outcome was insulin therapy in 3 cases (6.5%), oral medication in 25 cases (54.4%), and lifestyle intervention in 18 cases (39.1%). Conclusion:CS II for the treatment of newly diagnosed diabetes mellitus can effectively inhibit oxidative stress, improve the function of islet β cells, and exhibit long-term effects.

OBJECTIVETo explore the genetic basis for fetuses with cleft lip and palate.

METHODSFor 100 fetuses diagnosed with cleft lip with or without palate, G-banding chromosomal karyotyping and copy number variation sequencing (CNV-seq) were carried out on chorionic villi, amniotic fluid or cordocentesis samples.

RESULTSNo genomic abnormality was found among 49 fetuses with isolated cleft lip and palate, while 12 genomic aberrations were found among 51 fetuses with syndromic cleft lip and palate, which included 4 cases with trisomy 13, 2 cases with trisomy 18, 1 with X chromosome aneuploidy, 2 with other chromosomal aneuploidies and 3 with pathogenic CNVs.

CONCLUSIONThe incidence of genomic abnormalities in fetuses with cleft lip and palate was high. In addition to chromosomal abnormalities, attention should also be paid to pathogenic CNVs.

OBJECTIVETo investigate the value of intravascular ultrasound (IVUS) on assessing pulmonary vascular properties (PVPs) and its relationship with hemodynamics, and mortality rate in patients with pulmonary arterial hypertension associated with connective tissue disease (PAH-CTD).

METHODSPatients (n=51) with highly suspected PAH-CTD were prospectively enrolled in our department between July 2011 and March 2014. All patients underwent right heart catheterization (RHC) and IVUS, and were divided into 3 groups: PAH-CTD (n=25), PAH due to other reasons (n=15), and non-PAH control group (n=11). Based on IVUS, PAH patients were divided into distal (n=22) and proximal (n=18) remodeling subtypes.A total of 408 pulmonary segments were detected by IVUS, and all patients were followed up to (19 ± 10) months.

RESULTSIVUS evidenced higher mean wall thickness (MWT) ((0.30 ± 0.02) mm and (0.33 ± 0.02) mm vs. (0.21 ± 0.02) mm) and percentage of MWT (WTP) ((13.62 ± 0.59)% and (14.39 ± 0.77)% vs. (9.57 ± 0.97)%) values in PAH patients compared to control patients (all P<0.01). Pulmonary vascular mechanical properties (PVMPs) including compliance ((8.85 ± 0.82) × 10(-2)mm(2)/mmHg(1 mmHg=0.133 kPa) and (6.28 ± 0.65) × 10(-2)mm(2)/mmHg vs. (41.59 ± 5.02) × 10(-2) mm(2)/mmHg, all P<0.01), distensibility ((0.83 ± 0.09)%/mmHg and (0.55 ± 0.06)%/mmHg vs. (3.16 ± 0.38) %/mmHg, all P<0.01), elastic modulus ((169.25 ± 15.10) mmHg and (253.00 ± 22.11) mmHg vs.(43.78 ± 4.27) mmHg, all P<0.01) and stiffness index β (4.19 ± 0.41 and 5.18 ± 0.34 vs. 2.39 ± 0.27, P<0.05 or 0.01) in PAH groups were all significantly worse than in control group (all P<0.01). An inverse exponential association was found between PVMPs and hemodynamics with R(2) ranging from 0.544 to 0.777 (P<0.001). PVMPs tended to be better in group PAH-CTD than in PAH group due to other reasons.Mortality rate was similar between the two PAH groups, while PAH with distal remodeling subtype was linked with significantly higher mortality rate than PAH with the proximal remodeling subtype (23 % vs. 0, HR=10.14, P<0.05).

CONCLUSIONSIVUS plays an important role in the assessment of PAH-CTD patients in terms of evaluating PVPs and predicting mortality rate. PAH patients have deteriorated PVPs, but PVMPs tended to be better in PAH-CTD than in PAH patients due to other reasons. The mortality rate was similar between PAH groups, while PAH patients with the distal remodeling subtype is linked with a higher mortality rate than PAH patients with the proximal remodeling subtype.

OBJECTIVETo establish a near-infrared spectroscopy quantitative model for rapid determination of the patchouli alcohol content in Pogostemon cablin.

METHODThe gas chromatography was adopted for determining the content of patchouli alcohol content in 102 batches of P. cablin samples. Their near-infrared spectrograms were collected and preprocessed by standard normal variate and the first derivative of Savitsky-Golay. The quantitative model of patchouli alcohol content was established by the partial least squares regression analysis.

RESULTAccording to the correction model established in this study, the root-mean-square error of calibration, the root-mean-square error of prediction and the root-mean-square error of cross-validation of the calibration model for Patchouli alcohol were 0.991 10, 0.012 9, 0.012 8 and 0.033 15, respectively.

CONCLUSIONThe near-infrared spectroscopy quantitative model established in this study is stable, accurate and reliable for the rapid determination of the content of patchouli alcohol in P. cablin.

BACKGROUND: Coronary artery disease (CAD) is the commonest cause of heart failure (HF), whereas pulmonary hypertension (PH) has not been established or reported in this patient population. Therefore, we assessed the prevalence, risk factors, and survival in CAD-associated HF (CAD-HF) complicated with PH. METHODS: Symptomatic CAD-HF patients were continuously enrolled in this prospective, multicenter registry study. Echocardiography, coronary arteriography, left and right heart catheterization (RHC), and other baseline clinical data were recorded. Patients were followed up and their survival was recorded. RESULTS: One hundred and eighty-two CAD-HF patients were enrolled, including 142 with HF with a preserved ejection fraction (heart failure with preserved ejection fraction [HFpEF]; left ventricular ejection fraction [LVEF] ≥50%) and 40 with a reduced ejection fraction (heart failure with reduced ejection fraction [HFrEF]; LVEF < 50%). PH was diagnosed with RHC in 77.5% of patients. Patients with PH showed worse hemodynamic parameters and higher mortality. HFrEF-PH patients had worse survival than HFpEF-PH patients. CAD-HF patients with an enlarged left ventricular end-diastolic diameter and reduced hemoglobin were at higher risk of PH. Nitrate treatment reduced the risk of PH. Elevated creatinine and mean pulmonary arterial pressure (mPAP), diastolic pressure gradient (DPG) ≥7 mmHg, and previous myocardial infarction (MI) entailed a higher risk of mortality in CAD-HF patients with PH. CONCLUSIONS: PH is common in CAD-HF and worsens the hemodynamics and survival in these patients. Left ventricle enlargement and anemia increase the risk of PH in CAD-HF. Patients may benefit from nitrate medications. Renal impairment, elevated mPAP, DPG ≥7 mmHg, and previous MI are strong predictors of mortality in CAD-HF-PH patients.
