Objective To explore the bacterial drug resistance in blood culture in 2015 from the members of Antimicrobial Re-sistant Investigation Net of Shaanxi province,and to guide the clinicians touse antimicrobial drugs rationally.Methods All the objective bacterial isolates were collected and identifiedsusceptibility date by software WHONET 5.6.Results 6 871 bacterial isolates and their antibacterial susceptibilitydata were collected which included 3 199 (46.56%)Gram-negative bac-terial isolates and 3 672 (53.44%)Gram-positivebacterial isolates.The top five populationsof Gram-positive bacterial iso-lates were Staphylococcus epidermidis (30.94%),Staphylococcus hominis (17.84%),Staphylococcus haemolyticus (11.74%),Staphylococcusaureus (9.69%)and Enterococcus feacium (6.29%).The top five populationsof Gram-negative bacterial isolates were E.coli (43.67%),Stenotrophomonas maltophilia (14.63%),K.pneumoniae (13.47%), P.aeruginosa (4.13%)and Acinetobacter baumannii (3.63%).Theisolating rates of methicillin-resistant Staphylococcus aureus (MRSA)and methicillin-resistant coagulase negative Staphylococcus (MRCNS)were 31.2% and 76.1%,respec-tively.No vancomycin resistant Staphylococcusisolates were found.There were 0.9% E.faecium vancomycin-resistant iso-lates.The isolates of Enterobacteriaceae were still highly susceptible to carbapenem,whosetotal resistance rate was below 4.0%.The resistance rates of A.baumannii to most surveillance drugs in cludingimipenem were above 50.0% and the iso-lates of P.aeruginosa were still highly susceptible to most surveillancedrugs.Conclusion It is severe that the situation of bacterial drug resistance in blood culture in Shaanxi province.Should fullyuse bacterial drug resistance surveillance results for supervision and administration,and take effective measures forcontrolling the spread of resistant isolates.

Objective To evaluate the blood supply features and effectiveness of arterial chemoembolization for pedunculated hepatocellular carcinoma.Methods Angiography and chemoembolization via supplying blood arteries of tumor were performed in five patients with pedunculated hepatocellular carcinoma.Interventional procedure was carried out with tumor vascular infusion of 350 mg hot elemene emulsion and tumor embolization by cisplantin-lipidol emulsion(cisplantin 60-80 mg+lipidol 8-15 ml)and glutin.Results Ten interventional procedures(TACE)were undertaken in 5 patients.Angiography showed that tumor blood supply mainly coming from collateral circulation adjacent to the tumors,but partially from hepatic artery.Tumor sizes decreased from 30% to 50% in 5 cases,and AFP declined in 4 cases after the treatment. Conclusion Pedunculated hepatocellular carcinoma possessing different blood supply features from intrahepatocellular carcinomas.But transarterial ehemoembolization is still an effective method of choice for this treatment.

OBJECTIVETo evaluate the fetal cardiac function in gestational diabetes mellitus (GDM) pregnancies under different maternal glycemic controls.

METHODSForty four GDM mothers received 78 fetal echocardiographic evaluations at three gestational periods (<28, 28-34 and >34 weeks) and were divided into poorly-(DM1) and well-(DM2) controlled groups according to their glycemic control at examination. Seventy uncomplicated mothers were selected as controls. Parameters of fetal cardiac anatomy and function were measured and analyzed.

RESULTSGDM fetuses' cardiac ventricular walls were thicker than controls', and the differences between DM1 and DM2 were not significant except for end-diastolic left ventricular walls. In both GDM groups, the aortic flow velocities increased earlier than pulmonary artery and DM1 fetuses changed earlier than DM2 ones. GDM fetuses' left atrial shortening fraction was smaller than the controls' in the period of ⩾34 weeks and negatively correlated with thicknesses of left ventricular walls and interventricular septum in DM1 fetuses (r=-0.438 and -0.506). The right ventricular diastolic function in DM1 and DM2 fetuses decreased after the period of 28-34 weeks and in the period of >34 weeks respectively. Tei index of both left and right ventricles increased in DM1 group after the period of <28 weeks and in DM2 group only in the period of ⩾34 weeks, with no significant differences between DM1 and DM2 groups in this period.

CONCLUSIONFetuses of GDM mothers showed cardiac function impairments. Good maternal glycemic control may delay the impairments, but cannot reduce the degree. Some cardiac changes in GDM fetuses were similar to those in pregestational diabetic pregnancies except for several parameters and their changing time.

OBJECTIVETo study the feasibility of umbilical cord brain natriuretic peptide (BNP) level measurement for the evaluation of perinatal cardiac function in fetuses from pregnant women with abnormal blood glucose levels and the influence of abnormal blood glucose on fetal cardiac function.

METHODSTwenty-four mothers with gestational diabetes mellitus (n=18) or gestational impaired glucose tolerance (n=6) (diabetic group) were classified into two subgroups according to blood glucose level before delivery: good (n=17) and poor (n=7) glucose control. They underwent fetal echocardiography in their late pregnant periods and fetal cardiac sizes and function were measured. Twenty-five normal pregnant mothers served as the control group. Umbilical cord blood BNP concentrations were measured at delivery.

RESULTSThe umbilical cord blood BNP concentrations in the diabetic group were significantly higher than in the control group(114.0+/-39.0 pg/mL vs 80.6+/-13.7 pg/mL; p<0.01). The poor glucose control subgroup demonstrated higher umbilical cord blood BNP concentrations than the good glucose control subgroup (142.1+/-44.1 pg/mL vs 102.4+/-31.2 pg/mL; p<0.01). No difference was found between the gestational diabetes mellitus and the impaired glucose tolerance groups. The BNP concentration was positively correlated to the thicknesses of fetal left ventricular walls and the peak velocities of mitral A wave (r=0.715, 0.491 respectively, p<0.05), and negatively correlated to the mitral E/A ratio (r=-0.507, p<0.05).

CONCLUSIONSThe fetuses of pregnant women with abnormal blood glucose levels have an increased BNP level in umbilical cord blood. Umbilical cord BNP level is related to maternal blood glucose control and the changes in fetal cardiac function. It may reflex the latent impairments of fetal cardiac function. A good glucose control may decrease the impact of abnormal maternal blood glucose on fetal hearts.

OBJECTIVETo investigate the feasibility and clinical application value of selecting viable spermatozoa by noncontact diode laser.

METHODSWe obtained immotile spermatozoa from 2 infertile men with obstructive azoospermia or severe asthenospermia and selected viable spermatozoa using a single laser shot at the sperm tail. Those that responded to the laser shot by a curling reaction of the tail were regarded as presumably viable and used for intracytoplasmic sperm injection (ICSI).

RESULTSThe mean fertilization rate was 88.89% after ICSI with the laser-selected viable spermatozoa. Both of the embryo transfers resulted in a single pregnancy.

CONCLUSIONNoncontact diode laser is a useful alternative for the assessment of sperm viability, which may help to achieve successful pregnancy.
