OBJECTIVE To explore Ureaplasma urealyticum(Uu) infections in infertile patients.METHODS(Totally) 168(specimens) from infertile patients were cultured for Uu,then the drug susceptive test was done. (RESULTS) Fifty eight Uu strains were isolated for 168 specimens,the positive rate was 34.5%.The susceptive test result was showed that the highest susceptive antibiotics were minocycline and doxycycline,then were(clarithromycin),azithromycin and josamycin,but the highest resistant drug was sparfloxacin(37.9%).(CONCLUSIONS) The Uu infective rate in infertile patients is being rising,and it shows different resistance to(sparfloxacin) and other antibiotics.To diagnose and treat infertility,the Uu test and its susceptive test should be done routinely.

Objective To retrospectively compare the postoperative recovery and medical cost of pediatric patients underwent fast track cardiac anesthesia(FTCA,extubated in operating room)or regular anesthesia(extubated out of operating room).Methods From January 2005 to January 2006,108 children with congenital heart disease were operated under FTCA,108 patients who received regular anesthesia were set as a control group.The general characteristics,anesthetic method,postoperative treatments,recovery,and medical cost of the two groups were compared.Results The mean body weight of FTCA group was significantly higher than that in the control [(13.8?4.2)kg vs(10.9?3.8)kg,t=5.321,P=0.000].The patients received sevoflurane for anesthesia induction in the FTCA group were more than those in the control(58 vs 16,?2=36.260,P=0.000).The mean dosage of fentanyl used during operation in FTCA group was significantly lower than that in the control [(10.9?7.3)?g/kg vs(18.0?5.7)?g/kg,t=-7.697,P=0.000].In addition,fewer patients in FTCA group used more than one kind of sedative after the operation(7 vs 19,?2=6.296,P=0.012).95 patients in FTCA group returned to their ward without extubation-related complications.No significant difference in length of hospital stay was found between the two groups,however,the medical cost of FTCA group was significantly lower than that in the control(P

Objective It has been shown that aprotinin and tranexamic acid are equally effective in protecting platelet and reducing postoperative bleeding. The aim of this study was to compare the effects of aprotinin and tranexamic acid on blood coagulation. Methods Thirty patients undergoing elective valve replacement were randomly divided into two groups : (1) aprotinin group (AP, P

OBJECTIVE To investigate the distribution of drug resistance of Pseudomonas aeruginosa(PAE) among neonates and analyze the characteristic of the PAE infection.METHODS API system was used for the identification of 131 PAE clinical isolates and the resistance to 17 kinds antibiotics was determined by K-B method.RESULTS Most of 131 strains were isolated from sputum(42.0%) and gastric juice(32.8%).All strains were mainly isolated from neonate intensive care unit(NICU).The sensitivity to amikacin,levofloxacin,ofloxacin,ciprofloxacin,piperacillin/tazobactam,cefoperazone/sulbactam,imipenem and meropenem was respectively over 70.0%.PAE was inferior sensitivity to piperacillin,mezlocillin,cefoperazone,ceftriaxone,ceftazidime and aztreonam.CONCLUSIONS PAE is one of the most common pathogens causing nosocomial infection especially for neonates.Its susceptibility to antibiotics showed multidrug resistance.In order to reduce or prevent the occurrence of resistant isolate,we should rationally choose and use antibiotics combining with trait of neonate.

Ojective To study the anesthesia technique for video-assisted thoracoscopic coronary artery bypass surgery (VATCABS). Methods The anesthesia of 14 VATCABS were reviewed retrospectively. Results The average dose of Fentanyl was (13.3?7 3)?g/kg Six (42.9%) of 14 cases were extubated at the operating room, while other 8 cases (57.9%) were extubated (4.71?2.21) hours after operation. The time of ICU stay was (45.2?35.5) hours. No anesthesia related complications were found perioperatively. Conclusions "Fast track" anesthesia technique is suitable for VATCABS.

Information integration of heterogeneous systems needs implementing to meet the communication requirements of all subsystems of Hospital Information System (HIS). The solution is to introduce Health Level Seven (HL7), an international medical information exchange standard. With extensible Markup Language (XML) as the message-encoding manner, HL7 version 3 follows the object-oriented methodology. Based on the message system of HL7 version 3, this paper introduces an XML-based message processing technology and then testifies its feasibility.

Objective To evaluate the effects of inhaled iloprost on pulmonary hypertension after cardiopulmonary bypass in patients with congenital heart disease undergoing surgical correction of anomaly. Methods Fifty-eight patients with congenital heart disease aged 14-60 yr undergoing surgical correction of anomaly under cardiopulmonary bypass (CPB) were enrolled in this study. Radial artery was cannulated before induction of anesthesia. A 6-lumen pulmonary catheter was placed via right internal jugular vein after tracheal intubation. Their mean pulmonary arterial pressure was still > 25 mm Hg after operation. ECG, HR, BP, CO, PAP and SpO_2 were continuously monitored. Aerosolized iloprost 10 fig was inhaled via nebulizer after CPB. Hemodynamics were measured before iloprost inhalation (baseline) and at 0, 5, 15, 30 and 60 min after the end of iloprost inhalation. Results There were 28 patients with pulmonary hypertension after CPB among the 58 patients with congenital heart disease. Inhalation of iloprost 10μg significantly decreased mPAP, pulmonary vascular resistance and intrapulmonary shunt as compared with the baseline. Iloprost inhalation could also improve significantly CO and the mixed venous oxygen saturation (SvO_2 ). Conclusion Iloprost inhaled after CPB can effectively reduce pulmonary arterial pressure and pulmonary vascular resistance in patients with congenital heart disease undergoing surgical correction of anomaly and help them wean from CPB.

Objective To study the dosimetry parameters of 125I seed source (type Sinko BT-125-1) with thermoluminescent dosimeter (TLD) in the phantom.Methods The new type of phantom was modified to suit to measurement of a common type of 125I seed source.The AAPM TG43 protocol recommended measurements of dose-rate constant (Λ),radial dose function (gL (r)),and anisotropy function (F (r,θ)) have been performed in the phantom with TLD.Results The Λ was 0.928 cGyh-1 U-1.The gL(r) was determined at different radial distances r ranging from 1.0 to 10.0 cm with an interval of 1.0 cm ; and F (r,θ) at angles from 0° to 90° in 10° increments.The gL (r) of 125I seed source showed a difference of 9.6％ at the most in comparison to the corresponding values of 125I seed source (type Amersham 6711).The difference in F(2 cm,θ) of 125I seed source and Amersham 6711 was up to 10.2％ near the source end.With the phantom the combined standard uncertainty in the whole measurement was less than 6.0％.Conclusions The experimental results exhibit fairly small measurement uncertainties and good self-consistency.It's feasible to measure the dosimetry characters of permanent implant seeds in the modified phantom.

Objective To analyse the CT radiation dose statistically using the standardized radiation-dose-structured report (RDSR) of digital imaging and communications in medicine (DICOM). Methods Using the self-designed software, 1230 RDSR files about CT examination were obtained searching on the picture archiving and communication system ( PACS ) . The patient dose database was established by combination of the extracted relevant information with the scanned sites. The patients were divided into adult group (over 10 years) and child groups (0-1 year, 1-5 years, 5-10 years) according to the age. The average volume CT dose index ( CTDIvol ) and dose length product ( DLP) of all scans were recorded respectively, and then the effective dose ( E) was estimated. The DLP value at 75% quantile was calculated and compared with the diagnostic reference level ( DRL) . Results In adult group, CTDIvol and DLP values were moderately and positively correlated ( r=0?41 ) , the highest E was observed in upper abdominal enhanced scan, and the DLP value at 75% quantile was 60% higher than DRL. In child group, their CTDIvol in group of 5-10 years was greater than that in groups of 0-1 and 1-5 years ( t=2?42, 2?04, P<0?05);the DLP value was slightly and positively correlated with the age (r=0?16), while E was moderately and negatively correlated with the age ( r = -0?48 ) . Conclusions It is a simple and efficient method to use RDSR to obtain the radiation doses of patients. With the popularization of the new equipment and the application of regionalized medical platform, RDSR would become the main tool for the dosimetric level surveying and individual dose recording.
