A new group of gastric cancer associated antigens in sera of patients with rectal cancer, benign diseases and normal human were detected by MG series monoclonal antibodies against gastric cancer. The average values of normal persons plus 3 standard deviations was set as the highest limit of normal value. The positive rate were 69.7% (23/33) in sera of patients with rectal cancer, and 4%(1/25) in sera of patients with benign diseases. The values of MG-Ags were decreased to normal level 8-10 days after surgical removal in 5 patients of rectal cancer. The results of test suggest that determination of MG-Ags in serum of patients might be helpful in the diagnosis of rectal carcinoma.

Objective Hypothyroidism may have adverse effects on the post-operative outcomes. We evaluated the outcomes of coronary artery bypass grafting (CABG) in patients who had both coronary artery disease (CAD) and hypothyroidism.Methods Among 1347 patients undergoing CABG between September 2002 and June 2009, hypothyroidism was diagnosed in 21 patients (Group A, with 6 men and 15 women) and treated with thyroxin replacement therapy. The average age of patients in group A was(60.4 ± 10.2). Hypothyroidism was identified with tests for thyroid functions. CABG in 4 patients was performed with extracorporeal circulation, three of them received on-pump beating heart CABG, and in 17 patients was performed with off pump CABG( OPCAB). CABG was performed following the improvement of FT3, FT4 and TSH with the use of levothyroxine for all patients in group A Twenty patients with CAD in the absence of hypothyroidism ( group B) served as control, 4 of these patients underwent CABG with extracorporeal circulation. Data of thyroid function and hemodynamics pre-, post- and during operation were analyzed. Results Serum thyroid hormones, such as FT3, were measured with sensitive and specific radioimmunoassays peri-operatively. In the patients receiving CABG without extraorporeal circulation, the mean serum FT3 concentrations were ( 1. 39 ± 0. 36 ) pg/ml pre-operatively and ( 1.29 ± 0. 32 ) pg/ml post-operatively ( P = 0.18 ) for 17 cases in group A, and were (2.28 ±0.36)pg/ml and (2.19 ±0.34) pg/ml respectively (P =0.24)for 16 cases in Group B. In the patients receiving CABG with extracorporeal circulation, the mean serum FT3 concentrations were( 1.53 ±0.51 )pg/ml pre-operatively and (0.85 ± 0.40) pg/ml post-operatively ( P = 0. 04 ) for 4 cases in group A, and were ( 2.08 ± 0.24) pg/ml vs. ( 1.96 ±0. 26) pg/ml ( P = 0. 26 ) for 4 cases in group B. The CIs of patients in group A and group B were ( 2.7 ± 1.4)L · min-1 · m-2 vs. (2.8 ±1.5) L · min-1 · m-2, P=0.53). One patients with severe hypothyroidism and underwent CABG with extracorporeal circulation in Group A died of refractory bradycardia after failure in heart resuscitation. Twenty survivors in group A underwent coronary artery bypass on-beating heart. All survivors had improvement in cardiac function during 2to 30 months of follow-up, their preoperative ejection fraction (EF) was 0.48 ± 0.17 and follow-up EF was 0.55 ± 0. 21. All 20 patients in group B were alive. There was no significant difference between group A and B in hemodynamics, prognosis, duration of hospitalization [( 12.2 ±4.7 ) day vs. ( 10. 1 ± 3.9 ) day, P = 0.17], time to extubation [( 17.6 ± 9. 1 ) h vs.(15.1 ± 13.7) h, P =0.12]. Conclusion CABG in patients with both CAD and hypothyroidism is relatively safe. Proper peri-operative nanagement, combined with on-beating heart techniques of CABG, may decrease the operation risks. Off pump CABG had little effect on serum concentrations of FT3. Peri-operative thyroid replacement therapy was critical for patients with hypothyroidism. Patients with severe hypothyroidism who underwent CABG with extracorporeal circulation were at high risk.

OBJECTIVE: To study the therapeutic effect of treating knee arthropathy with total knee arthroplasty using rotating-platform knee prosthesis. METHODS: A total of 62 patients (74 knees) in Provincial Hospital Affiliated To Shandong University from January 2005 to January 2009 were selected, including 36 males (41 knees) and 26 females (33 knees), aged 52-79 years, mean aged 61.5 years; 28 cases with left knee, 22 cases with right knee and 12 cases of both knees. The cases were composed of 34 cases with osteoarthritis, 21 cases with rheumatoid arthritis and 7 cases with traumatic arthritis. All the patients received the total knee arthroplasty for the first time using rotating-platform knee prosthesis, no replacement of the patella. The clinical results of pre-operetion and after-operation were evaluated by the HSS knee rating score system. RESULTS: All the patients were followed-up for averaged 22 months (3-48 months) after operation. Incisions of all the cases were healed, and there was no infection and hematoma. Lower extremity deep venous thrombosis occurred in 2 cases at 3 days after operation. Swelling disappeared through drug treatment 10 days later. Pain and function of all the patients were obviously ameliorated after operation. The average HSS knee rating score was 44.99 (from 34 to 58) before total knee arthroplasty, which was improved to 88.78 (from 69 to 98), and the good-to-excellent rate was 98% (excellent 45 cases, good 16 cases, average 1 case). There were no signs of prosthetic dislocation or loosening in the X-ray films. CONCLUSION: Total knee arthroplasty using rotating-platform knee prosthesis owns advantages of easy surgical operation, tess complications, good recovery and satisfactory results in a short-term.

Objective To evaluate the performance of the Sino System for Coronary Operative Risk Evaluation ( SinoSCORE) on in-hospital mortality and postoperative complications in patients undergoing coronary artery bypass grafting (CABG) in a single heart center. Methods From January 2007 to December 2008, clinical information of 201 consecutive patients undergoing isolated CABG in our hospital was collected. The SinoSCORE was used to predict hospital mortality and major complications[sternal wound infection, postoperative renal failure, multiple organ dysfunction syndrome, perioperative intra-aortic balloon pumps ( IABP), etc.]after CABG among our study participants, which was initially designed as CBAG operative risk scoring system and included 11 risk factors. We estimated the predictable capability of SinoORE model by the means of analysing the calibration and discrimination characters of this risk scoring system. Calibration was evaluated with the method of Hosmer-Lemeshow goodness-of-fit test. Discrimination was tested by determining the area under the receiver operating characteristic (ROC) curve. The optimal cut-off point for SinoSCORE predicting major complications was obtained by the Youden index. Results Of all our study patients, the observed in-hospital mortality was 1.99% (4/201). The overall mean baseline age was ( 63.3 ± 9.2 ) years and 24.4% ( 49/201 ) were female. The predicted mortality cakulated by the SinoSCORE was 2.88% which was slightly higher than the actual mortality. SinoSCORE model slwed very high discriminatory ability and the good calibration power in predicting in-hospital mortality: Hosmer-Lemeshow calibration test:x2 =4. 304, P =0.744 and area under ROC was 0. 81 (95% CI: 0.687 -0.932). As for the major postoperative complications after CABG,SinoSCORE model still achieved a satisfactory performance with the good predictive value for the main complications risk evaluation such as postoperative renal failure, multiple organ dysfunction syndrome and IABP. Hosmer-Lemeshow: P =0.75, P =0. 75, P = 1.00; Areas under ROC respectively at was 0. 768 ( 95 % CI: 0.613 - 0. 924 ). 0. 832 ( 95 % CI: 0. 732 - 0. 932 )and 0. 737 (95% CI: 0. 607 -0. 867 ). The optimal cut-off points for SinoSCORE model predicting each of the above three major postoperative complications was ultimately determined to be 4.5. Conclusion In our patient database, the SinoSCORE model proved a good preoperative risk model in predicting both in-hospital mortality and major complications after CABG, which provides a realistic estimation of hospital death and post-operative complications risk for patients undergoing CABG. Sinoscore model is a suitable operative risk estimation system for Chinese CABG patients.
