Background and purpose: The ataxia-telangiectasia mutated (ATM) gene results in ataxia-telangiectasia (A-T) and it is closely associated with tumors. ATM is an important signal transducer that is involved in the repair of DNA double-strand break damage by phosphorylating numerous target proteins . This study was aimed to investigate the correlation between a single nucleotide polymorphism (SNP) in ATM gene (IVS62+60G>A) and the risk of non-small cell lung cancer(NSCLC) in a case-control study. Methods: From June 2004 to December 2005, a total of 264 patients with NSCLC were recruited, 264 healthy people as control. All of specimens were collected from Zhejiang Tumor Hospital. DNA was extracted from peripheral blood and then was used to determine. ATM genotype by Taqman SNP genotyping assays. Logistic regression model was employed to analyze the relationship between SNP and NSCLC risk. Results: The percentage of NSCLC patients in 86 patients with A/A genotype, 139 patients with A/G and 39 patients with G/G were 32.6% (86/264), 52.6% (139/264), 14.8% (39/264), respectively. The percentage in 68 healthy people with A/A genotype, 139 healthy people with NG and 55 healthy people with G/G were 26.0% (68/262), 53.0% (139/262) and 21.0% (55/262), respectively. The proportion of G/G genotype in 264 patients was obviously lower than that in the 264 healthy control (14.8% vs 21.2%, P<0.05). The people with G/G genotype had lower risk to NSCLC than there with A/A genotype (OR=0.561, 95% CI=0.334-0.942, P=0.029). Conclusion: The ATM SNP(IVS62+60G>A)was associated with the NSCLC risk, and homozygous G alleles may be a protective factor to NSCLC.

Objective To explore the influence of smoking on clopidogrel resistance in patients with coro-nary artery disease. Methods A total of 216 patients with coronary artery disease who accept selective percutane-ous coronary intervention in our hospital from May 2015 to December 2015 were selected as study subjects;their average age was 63 years old ,146 were male and 70 were female. All the patients were divided into clopidogrel resistance group (CR group) and normal clopidogrel response group (NCR group) according to the results of platelet aggregation test. History of smoking ,alcohol drinking and diabetes mellitus ,baseline medication uses , level of platelet counts,platelet distribution width,mean platelet volume,HbA1c,and results of echocardiogram and coronary angiography were compared between the two groups. Results The rate of smoking was significantly higher in CR group than in NCR group (P < 0.05). The changed value of PDW before and after treatment with clopidogrel was smaller in CR group than in NCR group ,the difference was statistically significant (P < 0.05). Conclusions Smoking may be a protective factor for clopidogrel resistance. The changed value of PDW before and after treatment with clopidogrel can reflect the level of clopidogrel resistance.

Objective To identify the metabolic levels in prefrontal lobe in patients with post-concussion syndrome by proton magnetic resonance spectroscopy (1H-MRS), and to explore the relationship between metabolic levels and executive function. Methods The study was conducted in 40 patients with post-concussion syndrome and 20 normal controls. 1H-MRS on prefrontal lobe was performed in patients and controls, the NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho + Cr) were determined. They were also evaluated executive functions by verbal fluency test (animal), Wisconsin Card Sorting Test (WSCT) and Tower of Hanoi (TOH). Results Compared with normal controls, the patients with post-concussion syndrome were significantly lower NAA/Cr and NAA/(Cho+Cr) ratios in left prefrontal lobe (P < 0.05). The NAA/Cr ratio in left prefrontal was significantly positive correlated with total scores of verbal fluency (r = 0.66, P < 0.05), categories of WSCT (r = 0.54,P < 0.05) and total score of TOH(r = 0.58, P < 0.05). The NAA/Cr ratio was significantly negative correlated with total errors (r = -0.53, P < 0.05) and persistent errors (r = -0.47, P < 0.05) of WSCT and mean executive time of TOH(r = -0.67, P < 0.05). Conclusions The metabolic levels of NAA in left prefrontal lobe in patients with post-concussion syndrome is significantly decreased , it is one cause of impaired executive functions.

The recovery force of Ti-Nb coated and uncoated TiNi shape memory alloy rods was investigated. The rods were 6.0 mm, 6.5 mm and 7.0 mm in diameter respectively. The mean transition temperature was 33.0 degrees C. The rods were stored at -18 degrees C and pre-bent with a three-point bending fixture, the span was 20. 0 centimeters and the deflections were 5.0 mm, 10.0 mm, 15.0 mm and 20.0 mm, respectively. The rods were then heated in a constant temperature saline solution chamber. The experimental temperature was 37.0 C and 50.0 C respectively. The recovery force was measured in a constant displacement mode on biomaterial test machine. The results showed that the recovery force of the memory alloy rod increased with increasing recovery temperature, rod diameter and deformation of both Ti-Nb coated and uncoated surface. The recovery force of Ti-Nb coated rods of 6.0 and 6.5 millimeter in diameter was lower than the uncoated rods in the same diameter. However, the recovery force of 7.0-mm-diameter rods showed no significant difference between coated and uncoated surface.

BACKGROUND: Preliminary study has prepared the three-dimensional silk fibroin/chitosan/nano-hydroxyapatite scaffold successfully.OBJECTIVE: To explore the mechanical properties, physical characteristics, chemical composition and antibiotic sustained-release ability of three-dimensional silk fibroin/chitosan/nano-hydroxyapatite scaffold loaded with levofloxacin. METHODS: Levofloxacin/chitosan (3:1) microspheres were constructed by emulsion settlement filter method. 5, 7.5 and 10 g of microspheres were added into 2% of silk fibroin/chitosan/nano-hydroxyapatite mixed solution through freeze drying and chemical cross-linking to obtain the scaffolds loaded with antibiotics. The scaffolds loaded with antibiotics underwent scanning electron microscope observation, and chemical composition analysis. The sustained release, mechanical properties, porosity, water absorption expansion rate and hot water soluble loss rate were detected. RESULTS AND CONCLUSION: (1) Scanning electron microscope observed that there were drug microspheres at the inner wall of the scaffold, and the voidage was decreased with mass of microspheres increasing. (2) Energy spectrum analysis showed that the three kinds of scaffolds were rich in calcium and phosphonium ions. (3) The three kinds of scaffolds showed the same releasing trend, which presented with sudden-release effect at the former 3 days (release> 50%) , and then tended to be stable. The release rate was the slowest in the scaffold loaded with 10 g of microscopes, and the rapidest in the scaffold loaded with 5 g of microscopes. (4) With the mass of microspheres increasing, there was an increase in the compressive and tension abilities and hot water soluble loss rate, and a decrease in the porosity, mean pore size and water absorption expansion rate. (5) These results indicate that the three-dimensional tissue-engineered scaffold loaded with levofloxacin is constructed successfully by freeze drying and chemical cross-linking method, which holds good sustained-release effect and compressive ability, water absorption expansion rate and hot water soluble loss rate.

Objective:Based on the principle that the aggregation-induced emission (AIE) fluorescent probe 6PD-DPAN could bind and aggregate with bacteria, and the fluorescence intensity could reflect the quantity of bacteria, a new method for rapid, convenient, and accurate bacterial drug sensitivity testing was established, which provided a basis for rapid and accurate clinical drug use.Methods:This was a methodological evaluation study. A total of 107 clinical isolates were collected from Houjie Hospital of Dongguan City from January to December 2022, among which 46 isolates were used for the establishment of the new method, and 61 isolates were used for methodological validation. The minimum inhibitory concentration (MIC) determined by broth microdilution method was used as the gold standard, and three antibacterial drugs, gentamicin, levofloxacin, and cefotaxime, were used as experimental drugs. The AIE plate was incubated for 4 hours, and the fluorescence intensity was measured every half an hour to draw a fluorescence change curve. The MIC results were compared with the CLSI breakpoints to determine the bacteria as sensitive, intermediate, or resistant. To simplify the detection process, the ratio of fluorescence intensity at 4 hours(R) was calculated, and the ROC curve was used to analyze the efficacy of R in determining bacterial growth and establish its cutoff value. The new method was used to determine the MIC of 61 clinical isolates, with broth microdilution method as the gold standard. The basic consistency, categorical consistency, very major errors, and major errors of the new method were analyzed, and the consistency between the two methods was determined by the Kappa test.Results:ROC curve analysis of the R after 4 hours of culture: The cut-off value was 3.0, with both sensitivity and specificity for determining bacterial growth being 100%. The median (interquartile) R for bacterial growth inhibition was 11.1 (8.6, 14.4); the median R-value for bacterial growth was 1.1 (1.0, 1.2). Compared to the gold standard, the newly established method showed 100% (61/61) essential agreement in detecting MICs of 61 clinical isolates, with a categorical agreement of 96.7% (59/61). There were no very major or major errors, and the Kappa value was 0.94, indicating good consistency between the newly established method and the microbroth dilution method.Conclusions:This study successfully established a new method for bacterial drug sensitivity testing based on AIE technology, which could obtain satisfactory results within 5 hours, providing a basis for early precision drug treatment in clinical practice.
