Crystal power/epoxy resin composite was made with refined crystal power as filling material in different composition. The shearing strength and coefficient of thermal expansion of the crystal powder/epoxy resin composite was studied. The sectional morphology was observed under a scanning electron microscope. The results of the study indicate that the shearing strength of crystal powder/epoxy resin composite is improved while the coefficient of thermal expansion decreases with increase of the amount of crystal powder, and a well-proportioned three-dimensional structure is obtained. The augmentation of shearing strength exhibits no linear relationship to the amount of crystal powder, and there is an optimal amount for crystal powder filling. The coefficient of thermal expansion is decreased with increase of crystal powder filling, and three-dimensional structure optimization exhibits the' similar inflexion.

Objective To investigate the effects of biatrial infusion on pulmonary artery pressure (PAP)after cardiopulmonary bypass (CPB) in patients undergoing mitral valve replacement.Methods Twenty NYHA Ⅱ or Ⅲ patients aged 22-53 yr weighing 34-57 kg undergoing mitral valve replacement complicated by pulmonary hypertension (mean pulmonary artery pressure (MPAP) ＞ 50 mm Hg) were randomly divided into 2 groups ( n = 10 each): infusion via right atrium group (group R) and infusion via both atria group (group B). After induction of anesthesia, a three cavity floating Swan-Ganz catheter was placed via right internal jugular vein to monitor CVP,PAP, pulmonary capillary wedge pressure (PCWP) and CO. The patients received infusion of prostaglandin E1 30-150 ng· kg- 1 · min - 1 and phenylephrine 0.2-0.6 μg· kg- 1 · min- 1 via central veins in group R and infusion of prostaglandin E1 30-150 ng·kg-1 ·min-1 via central veins and phenylephrine 0.2-0.6 μg·kg-1 ·min-1 via left atrium in group B. MAP, HR, MPAP, PCWP, CVP and CO were recorded 5 min before administration (T0), and 5,10, 30 and 60 min after administration (T1-4). Pulmonary vascular resistance index (PVRI), systemic vascular resistance index (SVRI) and CI were also calculated. Results D:\1111111111\MDB\zhmzxzz98201008.mdbCompared with the value at T0, MAP, MPAP, PCWP and PVRI were significantly decreased, while CI was increased at T1-4 in group R, and MAP, CI and SVRI were significantly increased, while HR, MPAP, PCWP, CVP and PVRI decreased at T1-4 in group B ( P ＜ 0.05).MAP, CI and SVRI were significantly higher, while HR, MPAP, PCWP, PVRI and CVP lower in group B than in group R ( P ＜ 0.05). Conclusion Biatrial infusion can effectively reduce PAP and pulmonary vascular resistance after CPB in patients undergoing mitral valve replacement.

Objective　 This paper was designed to investigate the feasibility of non-invasive prenetal diagnosis of Duchenne muscular dystrophy(DMD). Methods　 The nucleated red blood cells(NRBC) were separated with percoll using a discontinuous density gradient method. The cells were smeared on microscope slides using a cyto-centrifuge and then stained by Wright-Giemsa. NRBCs were detected and individually retrieved into glass capillary pipettes using a micromanipulator under microscopic observation. The whole genome of a single cell was amplified by improved primer extension preamplification(PEP). The procedures for making prenatal diagnosis of DMD and determining the origin of NRBCs proceeded at the same time using sex determination and linkage analysis of several STR loci of dystrophin. Genotypes were analyzed by amplifying the 9 STR fragments using fluorescence-PCR technique and NRBCs origin was further determined. Results　 A case of DMD in male fetus was diagnosed. Conclusion　 With the use of the method reported, the non-invasive prenatal diagnosis of DMD is possible.

Objective To detect the DMD gene mutation sites and the regions of breakpoints in Duchenne/Becker muscular dystrophy (DMD/BMD) patients in northern China. Methods Multiplex amplifiable probe hybridization (MLPA) was used to detect the mutation in 59 cases (51 cases with DMD and 8 with BMD) from northern China and dystrophin gene mutations in their parents. Results From northern China and dystrophin gene mutations 59 families found gene deletions in 33 cases of 59 DMD/BMD patients (55.9%), duplications in 6 cases (10. 2%) and point mutation in one case (1.7%). Intron 44 was most frequently affected (n = 13, 33.3%), followed by intron 50 (n = 11, 28.2%) and intron 45 (n=8, 20.5%). The novel mutations were identified, in two patients including two independent duplications carried by patient D1 149 and a point mutation [5208del(A)] carried by patient D1 65, which were not included in Leiden database. In addition, an exon 22 deletion was found in one patient, which was the first reported case in Chinese patients. Conclusions Deletions are mostly located in the hotspot between exon 45 and 50. Duplications mostly occurred in the 5' end of the gene. Intron 44 is the most frequently affected breakpoint in northern Chinese population.

Objective In order to prevent the infection of Acinetobacter baumannii and use antibiotics rationally,the clinical infection and drug resistant data of multi-drug resistance Acinetobacter baumannii (MRAB)detected in intensive care unit (ICU)of Beijing Friendship Hospital from 2011 to 2013were analyzed.Methods This study is a retrospective study.One hundred and eighty five strains of MRAB were collected from the patients in ICU from January 2011 to December 2013.Identificationand antibiotic susceptibility of strains were determined with Vitek-2 Compact automatic bacteria identification system.The annual infection rate of MRAB was counted.PCR was used to detect the resistance genes.The clinical features of the patients with MRAB were analyzed.The average age,acute physiology and chronic health evaluation (APACHE) Ⅱ score,duration in ICU and mortality ratio of the MRAB patients were compared with the patients without MRAB.Rank-sum test was used to analyze the average age,APACHE Ⅱ score and duration in ICU.Chi-squared test was used to analyze the mortality ratio and annual infection rate.Results The average age [(67 ± 17)vs (59-± 19) years old,Z =-5.365,P =0],APACHE Ⅱ score [(25.68±7.93) vs (17.62±8.39),Z=-14.821,P=0],duration in ICU [(27 ±29) vs (5 ±8) d,Z =-4.342,P =0] and mortality ratio [10.82％ (53/185) vs 28.65％ (147/1 359),x2 =45.92,P =0] of the patients infected by MRAB were significantly higher than those without the infection.The MRAB was found mostly in sputum and bronchial precipitates (83.78％,155/185).Though detection rate reduced yearly and there was a significant reduction in 2013 compared with 2011 [11.07％ (69/469) vs 8.37％ (52/621),x2 =8.755,P =0.003],the drug resistant rate was in high level and did not show any change in the 3 years.OXA-23 and OXA-51 were detected in all MRAB.Conclusions The main drug resistant mechanism of MRAB in ICU is related to OXA-23.More active methods of coutrol and prevention of MRAB should be used in elderly aud severely pneumonic patients.Intensive disinfection and isolation measures can decrease MRAB detection rate.Combined antibiotics should be used in patients with MRAB infection.
