Objective To determine the relationship between end-tidal carbon dioxide tension (PET CO 2 )obtained from the distal ends of the tracheal tube and arterial pressure of carbon dioxide (PaCO 2 ) compared with the sidestream capnometer in infants with congenital heart disease. Methods Twenty infants undergoing congenital heart disease surgery,12 males and 8 females,aged 3-48 months,ASA physical statusⅠ-Ⅲ were enrolled.Measurements of PET CO 2 were obtained from the distal ends of the tracheal tube using a sterile 22 G catheter that was inserted into the tube and from the proximal end with a sidestream capnometer in 20 intubated infants with congenital heart dis-ease.The data including PET CO 2 and the arterial PaCO 2 were obtained both after the anesthesia induc-tion and the CPB.Results The data of PET CO 2 obtained from the distal ends of the tracheal tube after the anesthesia induction [(36.8 ±2.7)mm Hg vs.(32.5 ± 1.4)mm Hg,P <0.05 ]and the CPB [(40.8±2.5)mm Hg vs.(36.5±1.6)mm Hg,P <0.05]were both higher than those from the proximal end with a sidestream capnometer.The difference between PaCO 2 and PET CO 2 obtained from the distal ends of the tracheal tube after the induction [(7.1 ±0.7)mm Hg vs.(1 1.4 ± 1.5 ) mm Hg,P <0.01]and the CPB [(9.3±1.2)mm Hg vs.(13.5±2.3)mm Hg,P <0.01]were sig-nificantly lower than that between PaCO 2 and PET CO 2 obtained from the proximal end.Distal side-stream PET CO 2 correlated with the PaCO 2 (R 2 =0.94 after induction and R 2 =0.93 after the CPB,P<0.05).However,the proximal PET CO 2 with the sidestream capnometer correlated very poorly with PaCO 2 whether after the induction (R 2 = 0.68,P < 0.05 )nor the CPB (R 2 = 0.66,P < 0.05 ). Conclusion We conclude that the PET CO 2 obtained from the distal ends of the tracheal tube provides accurate estimates of the PaCO 2 in critically ill infants with congenital heart disease.

respectively)was significantly higher than that for digital anterograde venography (0.684 and 0.587,P =0.026,respectively).Conclusion Diagnostic accuracy and detection rate of residuaI or recurrent varicose veins with CT phlebography are found to be more superior than that with digital anterograde venography which has high guidance value in preoperation and assesses the efficacy of post-surgery treatment.

Objective To investingate the role of inflammation in coronary atherosclerosis and the relationship between the inflammatory factors and coronary risk score. Methods 56 patients with acute coronary syndrome were studied, among them 26 cases were diagnosed as acute myocardial infarction (AMI) and 30 unstable angina pectoris (UAP). The study group was compared with a control group of 30 cases who were identified as normal by coronary angiography. The concentrations of serum sICAM-1 and hsCRP were determined by ELISA assay. The coronary risk score was recorded in patients with UAP. Results Serum sICAM-1 levels were significantly elevated in patients with AMI or UAP compared with that of control group, while higher hsCRP level was observed only in the patients with AMI compared with those with UAP and the control group. By linear regression analysis, only serum sICAM-1 levels were correlated with coronary risk score (r=0.445, P

Objective To assess the diagnostic and curative efficacy of laparoscopy combined with hysteroscopy for tubal infertility. Methods A combined use of laparoscopy and hysteroscopy was performed in 62 cases of tubal obstructive infertility (124 oviducts), which had been tentatively diagnosed by lipiodol hysterosalpingography (HSG). Results Out of the 62 cases, 11 cases (22 oviducts) were found bilaterally unobstructed (17.7%, 22/124), 8 cases (8 oviducts) were found unilaterally unobstructed (6.5%, 8/124). Tubal interstitial or isthmus obstruction was observed in 40 oviducts (32.3%, 40/124) and hydrosalpinx in 54 oviducts (43.5%, 54/124). The consistency ratio between lipiodol HSG and endoscopy in the diagnosis of tubal obstruction was 75.8% (94/124). Tubal catheterization under hysteroscope and laparoscope was adopted in the 40 ducts of interstitial or isthmus obstruction, and 30 were cured, 5 perforated and 5 failed. Laparoscopic salpingostomy and salpingolysis was employed successfully in 54 tubes. Conclusions Combined use of hysteroscopy and laparoscopy is useful in the diagnosis and treatment of tubal obstruction and infertility tentatively diagnosed by HSG.

Objective To investigate the affect of rhTNFR:Fc on the postoperative recovery of patients with inflammatory arthritis after arthroplasty. Methods Patients with inflammatory arthritis undergoing arthroplasty were included and divided into rhTNFR:Fc group (rhTNFR:Fc only or combined with conven-tional DMARDs) and conventional DMARDs group (monotherapy with or combination of conventional DMARDs). We retrospectively analyzed the incidence of postoperative infection, wound healing time, the febrile period (body temperature ≥37.5 ℃) and the duration of antibiotics treatment after arthroplasty. x2 test and t test were used for statistical analysis. Results Sixty-seven patients were included, 18 in the rhTNFR: Fc group and 49 in the conventional DMARDs group. One postoperative infection occurred in rhTNFR :Fc group but none in the DMARDs group. There was no significant difference by Fisher's exact test (P＞0.05). The febrile duration was (4±3) days in the rhTNFR :Fc group and (3±3) days in the conventional DMARDs group, the difference was not statistically significant (P＞0.05). The wound healing time was (14.0±3.1) days in the rhTNFR :Fc group and (14.7±2.9) days in the conventional DMARDs group, which was not statistically different(P＞0.05). The duration of antibiotics treatment after operation was (14.8±9.3) days in the rhTNFR: Fc group and (10.3±2.7) days in the conventional DMARDs group, the difference was statistically significant (P＜0.05). Conclusion Using rhTNFR:Fc during perioperative period in patients with inflammatory arthritis does not increase the risk of infectious complications or extending wound healing time and the febrile duration.
