A young female complained repeated nasal discharge for over three months with discomfort of right cheek, and oral antibiotics had less effect. She has a history of "root canal therapy" five years before. Physical examination found purulent secretion in the right middle nasal meatus, and light tenderness in the right side of the maxillary sinus area. The CT scan of paranasal sinus shown possible fungal infection of right maxillary sinus. Finally the nasal endoscopic surgery confirmed the fungus ball of right maxillary sinus with foreign body (the root canal filling material).

Objective To search for clinical appearance and fungal resistance of candidemia in ICU.Methods Thirty-four cases of candidemia in ICU during 2003and 2006 were analyzed retrospectively.Results Twelve of 34 cases of candidemia were C.albicans,and 22 of 34 cases were non-C.albicans,which were 64.71% in candida monilia.Fever and chill of candidemia were 100% and 70.59% differently.Conclusion If there is high risk factor of fungous infection in clinic,at the same time fever and chill appear,and antibiotics treat is inefficacy not effective,it is possible to consider candidemia.

Objective To develop a method for localizing a detecting capsule in the gastrointestinal tract.Methods A three-axis magnetic sensor was sealed in the detecting capsule.Three flat coils were fixed on patients' back.The coils were excited one by one to generate electromagnetic fields.The position and the orientation of the capsule could be determined by telemetering the signals from the magnetic sensor incorporated in the capsule.Results The telemetric localization system worked successfully.A localization model describing the relationship between the magnetic field strength and the position and orientation of the capsule,was correctly established basing on the principle of magnetic dipoles,and neural network algorithm was employed to solve a non-linear equation set.Conclusion The results showed that the localization method is feasible and the precision is higher than existing methods.The localization device can perform consecutive tracking and can be made into a portable type.After putting into practice,the device can also be used in food selection for astronauts by monitoring their gastrointestinal parameters in space.

Objective To investigate the relationship between plasminogen activator inhibitor(PAI) activity and coronary artery disease(CAD) in elderly patients. Methods Plasma samples from 93 patients with CAD were analyzed for the PAI activity, plasminogen activator(t-PA) activity, serum levels of cholesterol and triglyceride. The values of these parameters were compared between the CAD and the control groups. Results Higher plasma PAI activity 〔(810?360) AU/L vs. (640?300) AU/L,P

The activities of acid phosphatase and ?-1,4 glucosidase and the concentration of citric acid in the semen of 51 cases of chronic prostatitis were determined.The mean value was 694.33?346.61 Bodansky units for acid phosphatase,43.84?24.70mIU/ml for ?-1,4 glucosidase,and 3.26 ?2.37 mg/ml for citric acid.The activity of acid phospohatase and the concentration of citric acid were significantly lower in the patients with chronic prostatitis than in the normal subjicts while the activity of ?-1,4 glucosidase showed little changes.The findings suggest that the functions of the prostate was severely imparired and that of the epididymis remained normal in patients with chronic prostatitis.

Objective To investigate the time and risk factors for spontaneous closure of patent ductus arteriosus (PDA) in preterm infants. Methods One hundred and seventy-seven preterm infants with arterial ductus unclosed were divided into three groups according to their gestational age as 28-31+6 weeks group (n=44),32-34+6 weeks group (n=59) and 35-36+6 weeks group (n=74).PDA was diagnosed by echocardiography in time of ≤12 h,-24 h,-48 h,-72 h,-96 h,-120 h,-144 h and >144 but ≤168 h after birth.The parameters of cardiac function included peak flow rate of aorta valve orifice,peak flow rate of pulmonary artery valve orifice,cardiac output,stroke volume,ejection fraction,the ratio of early (E) and late (A) diastolic velocities of mitral and tricuspid valves.The risk factors of arterial ductus spontaneous closure were determined by Logistic regression analysis.Results The cumulative spontaneous closure rates of preterm infants in three groups were 95.5%,100.0% and 100.0% within 168 h after birth respectively. There were significant differences of cumulative spontaneous closure rate in different time among three groups (x2 =4.23,7.45,12.46,7.14,4.75,6.47,3.89 and 3.89 respectively,P<0.05).After spontaneous closure of PDA during 12-24 h, peak flow rate of pulmonary artery valve orifice increased [(0.69±0.12) cm/s vs (0.65±0.12) cm/s,t=2.37,P=0.02],peak flow rate of aorta valve orifice [(0.65±0.11) cm/s vs (0.69±0.12) cm/s,t=2.51,P=0.02] and ejection fraction [(63.00±8.50) % vs (66.00±8.50) %,t=2.34,P=0.02] decreased.Logistic regression analysis showed that,the risk factors of preterm infants with arterial ductus unclosed within 24 hours after birth were gestation age (OR =1,825,95%CI:1.239-2.689),1 min Apgar score 0-3 (OR=1.946,95%CI:1.572-3.527) and early onset sepsis (OR=3.215,95%CI:1.245-5.463) ; gestation age (OR=3.270,95%CI:1.852-5.774),twins (OR=3.634,95%CI:1.489-8.871),1 min Apgar score 0-3 (OR=3.752,95%CI:2.156-5.436),Ⅲ-Ⅳ stage of respiratory distress syndrome (OR=2.897,95%CI:1.764-5.348) and early onset sepsis (OR=3.172,95%CI:2.134-6.437) were the risk factors of preterm infants with arterial ductus unclosed during 24-48 hours after birth; and gestational age (OR=2.471,95%CI:1.087-5.613),1 min Apgar score 0-3 (OR=2.985,95%CI: 1.469-5.736), Ⅲ-Ⅳ stage of respiratory distress syndrome (OR =3.645,95% CI:1.879-6.282),fluid volume excess (OR =4.135,95%CI:2.146-7.428) and early onset sepsis (OR=3.246,95%CI:2.146-4.526) for those with arterial ductus unclosed during 48-72 hours after birth. Conclusions The spontaneous closure rate of arterial ductus in the newborn infants whose gestational age over 28 weeks was above 90% in the first week after birth.There was no difference of left ventricular pump function between before and after the spontaneous closure.Reducing the incidence of premature birth,twins,severe asphyxia,severe respiratory distress syndrome, fluid excess and early onset sepsis might improve the spontaneous closure of arterial ductus.

Objectives:To study the impact of nutritional support in non operative management of severe acute pancreatitis. Methods:Sixteen patients with severe acute pancreatitis were provided with stage nutritional support. Results:Fourteen cases fully recovered and 2 cases died. Stage of maintenance equilibration was (57.0?12.5)hours,TPN was (12.1?4.2)days and PN+EN was (12.2?3.5)days. Conclusions:Stage nutritional support might be favourable in improving prognosis and survival rate of severe acute pancreatitis.

Objective To report the preliminary results of placing metallic stent and ~(125)Ⅰ seed strand combined with transcatheter arterial chemoembolization (TACE) for the treatment of hepatocellular carcinoma (HCC) with inferior vena cava (IVC) obstruction. Methods From March 2009 to June 2009, implantation of radioactive ~(125)Ⅰ seed strand and metallic stent combined with TACE treatment was performed in 8 cases of HCC with malignant IVC obstruction. All patients were males with a mean age of (60.6 ± 9.6) years, ~(125)Ⅰ seed strand and Z-type soft-expandable metallic stent were placed in the obstructive segment of IVC, which was followed by TACE. Before and after the treatment, the diameter of the obstructive segment of IVC, the pressure gradient between right atrium and distal end of obstructive segment of IVC, and the symptoms related to the obstruction were estimated and recorded, the results were compared individually. Clinical follow-up was conducted in all patients. Results A total of 8 stents and 10 ~(125)Ⅰ seed strands were placed in the obstructive segment of IVC. Altogether 138 ~(125)Ⅰ seeds were implanted in 8 patients. Obvious clinical improvements were obtained after therapy. No complications occurred in all patients except one patient who experienced acute renal dysfunction at the second day after therapy. During a mean of (2.1 ± 0.6) months follow-up, occlusion of IVC stent was detected in 1 patient. The remaining stents remained patent. Conclusion Our initial results indicate that placement of ~(125)Ⅰ seed strand and metallic stent combined with TACE is a safe and feasible therapeutic option for advanced HCC with malignant IVC obstruction.
