Objective To investigate the efficacy of externally applied diclofenac diethylamine emulgel on the prevention of PICC-induced mechanic phlebitis. Methods One hundred cancer patients with PICC were divided into two groups. diclofenac diethylamine emulgel and mucopolysaccharide polysulfate cream were applied three times a day for 7 days after catheterization in the two groups,respectively. Results There was no significant difference on the incidence of mechanic phlebitis between the two groups (4% vs. 8%,P>0.05). Conclusion The efficacy of externally applied diclofenac diethylamine emulgel on the prevention of PICC-induced mechanic phlebitis is the same as mucopolysaccharide polysulfate cream. Except their common virtue of convenient and simple operation,the price of diclofenac diethylamine emulgel is lower than mucopolysaccharide polysulfate cream and worthy to be spread in clinical practice.

Objective To evaluate the relationship between maternal antepartum fever and early-onset neonatal bacterial sepsis.Methods A retrospective multi-centred clinical study of 404 neonates including 103 new borns with maternal antepartum fever and 311 neonates without was conducted.Results The frequency of early-onset neonatal bacterial sepsis was significantly higher in neonate with maternal antepartum fever than those without(4.9% vs 0.3%,P=0.001).Both maternal antepartum temperature ≥39℃ and maternal postpartum fever lasting several days was higher suggested the possibility of neonatal sepsis.Conclusions The neonates born with high risk factor of early-onset neonate bacterial sepsis require comprehensive lab evaluation including blood culture and uterine culture,clinical observation and aggressive treatment to decrease the mortality.

Objective To evaluate the clinical outcomes of sirolimus-eluting stenting in patients with coronary artery disease and type 2 diabetes.Methods Among 101 patients with coronary artery disease and type 2 diabetes who underwent percutaneous coronary intervention, 67 received sirolimus-eluting stents (SES group) and 34 were treated only with bare metal stents (BMS group). Baseline clinical characteristics, procedural success rate, occurrence of cardiac events during follow-up were recorded and compared between the two groups. Results The procedural success rate was 100% in both groups. During follow-up(average one year), the SES group patients had significantly lower occurrence of cardiac events than those in the BMS group ( 7.5% vs. 32.4%, P= 0.001).Conclusions Sirolimus-eluting stent implantation for patients with coronary artery disease and type 2 diabetes is safe and can reduce major adverse cardiac events in long-term follow-up.

OBJECTIVEThe interrelation of yield and agronomic traits of Gentiana rigescens was studied for the germplasm and breeding variety of this species.

METHODTwelve agronomic traits, root diameter, root length, root number, root biomass, stem diameter, plant height, the first branch number, leaf length, leaf width, leaf length/leaf width ratio, calyx length, and calyx number of G. rigescens from 26 wild populations in Yunnan were determined for correlation analysis, multiple stepwise regression analysis and path analysis.

RESULTCorrelation analysis showed that there were significantly positive correlation between the traits of aboveground part and the length, diameter, number, and biomass of the root. Multiple stepwise regression analysis showed that length, width, and number of root, plant height, the first branch number, and the calyx number were the main factors that affected the root biomass. Path analysis showed that the diameter, length, and number of the root, the stem height, and the first branch number had a direct positive effect on the root biomass.

CONCLUSIONThe traits, such as high and strong stem, high number of first branch number and shrubby shape could be selected for the breeding and high yielding of G. rigescens.

OBJECTIVETo investigate whether or not the gamma-aminobutyric acid (GABA) receptor subtype A genes GABRA5 and GABRB3 are associated with childhood absence epilepsy (CAE).

METHODSTwo microsatellite DNA, GABRA5 and GABRB3, adjoining to chromosome 15q11.2-q12 were used as genetic markers. Both case-control study and transmission/disequilibrium test (TDT) as well as fluorescence-based semi-automated genotyping technique were used in 90 trios with CAE and 100 controls to conduct association analysis.

RESULTSThe allele frequencies of the 2 microsatellite DNA in Chinese normal population are in good agreement with Hardy-Weinberg equilibrium. The polymorphism information content of microsatellite DNA GABRA5 and GABRB3, are 0.80 and 0.66 respectively. The allele 2 frequency of microsatellite DNA GABRA5 and the allele 5 frequency of microsatellite DNA GABRB3 are significantly higher in CAE patients than those in normal controls(P<0.001).

CONCLUSIONBoth microsatellite DNA GABRA5 and GABRB3 are good genetic markers. The gamma-aminobutyric acid receptor subtype A genes GABRA5 and GABRB3 may be directly involved either in the etiology of CAE or in linkage disequilibrium with disease-predisposing sites.

OBJECTIVE: To study the prevalence and clinical characteristics of decreased myocardial blood flow (MBF) quantified by dynamic computed tomography (CT) myocardial perfusion imaging (MPI) in symptomatic patients without in-stent restenosis. MATERIALS AND METHODS: Thirty-seven (mean age, 71.3 ± 10 years; age range, 48–88 years; 31 males, 6 females) consecutive symptomatic patients with patent coronary stents and without obstructive de novo lesions were prospectively enrolled to undergo dynamic CT-MPI using a third-generation dual-source CT scanner. The shuttle-mode acquisition technique was used to image the complete left ventricle. A bolus of contrast media (50 mL; iopromide, 370 mg iodine/mL) was injected into the antecubital vein at a rate of 6 mL/s, followed by a 40-mL saline flush. The mean MBF value and other quantitative parameters were measured for each segment of both stented-vessel territories and reference territories. The MBFratio was defined as the ratio of the mean MBF value of the whole stent-vessel territory to that of the whole reference territory. An MBFratio of 0.85 was used as the cut-off value to distinguish hypoperfused from non-hypoperfused segments. RESULTS: A total of 629 segments of 37 patients were ultimately included for analysis. The mean effective dose of dynamic CT-MPI was 3.1 ± 1.2 mSv (range, 1.7–6.3 mSv). The mean MBF of stent-vessel territories was decreased in 19 lesions and 81 segments. Compared to stent-vessel territories without hypoperfusion, the mean MBF and myocardial blood volume were markedly lower in hypoperfused stent-vessel territories (77.5 ± 16.6 mL/100 mL/min vs. 140.4 ± 24.1 mL/100 mL/min [p < 0.001] and 6.4 ± 3.7 mL/100 mL vs. 11.5 ± 4 mL/100 mL [p < 0.001, respectively]). Myocardial hypoperfusion in stent-vessel territories was present in 48.6% (18/37) of patients. None of clinical parameters differed statistically significantly between hypoperfusion and non-hypoperfusion subgroups. CONCLUSION: Decreased MBF is commonly present in patients who are symptomatic after percutaneous coronary intervention, despite patent stents and can be detected by dynamic CT-MPI using a low radiation dose.
