Objective To discuss the relationship between antibiotic prophylaxis and surgical site infection(SSI) in colorectal cancer.Methods A survey of 880 patients with colorectal cancer from Jan.1998 to Dec.2008 were studied.Patients were divided into two groups by antibiotic duration: ≥24 h group(n=401) and 0.05).Conclusion Longer operation time,more blood loss and longer bleeding time are the risk factors of surgical site infection.Moreover prolonged antibiotic prophylaxis can not decrease the incidence of SSI.

Objective To compare the value of ELISA and indirect immunofluorescence (IIF)method in diagnosis for autoim-mune diseases.Methods A total of 33 patients in systemic lupus erythematosus(SLE)group,59 patients in other autoimmune dis-eases group,43 patients in non-autoimmune disease group,20 people accepted physical examination in control group.The antinuclear antibody (ANA)in each group were detected by two methods and analyzed.Results The high titer ANA detected by ELISA and IIF in SLE group and other autoimmune diseases group were (2.621±1.700),(2.248±1.781);(2.71 5±0.730),(2.544±0.59). The titer ANA detected by ELISA in non-autoimmune disease group was (1.034±1.050),which was lower than(2.253 ±0.691) detected by IIF.Conclusion ELSA might improve the detection effects of ANA antibody.

Objective To observe the effect of serum containing Qiangjijianli oral liquid in-vitro proliferation of rat mesenchymal stem cells (MSCs). Methods Rat mesenchymal stem cells dissociated from the bone marrow by density gradient method were cultured. MSCs were identified by marking of bromodeoxyuridine (Brdu) and staining of CD44, CD45. Experimental group was cultivated with serum containing Qiangjijianli oral liquid and control group with blank serum. Optical absorption value of MSCs was stained by methyl thiazolyl tetrazolium (MTT). Results Serum containing Qiangjijianli oral liquid at different concentrations could promote the proliferation of MSCs, the difference being significant in comparison with the control group (P

Objective To explore the effect of the antero-posterior translation of the femur on the maximum knee flexion and the relative movement of the femur for the three different kinds of prosthesis after total knee arthroplasty(TKA), such as posterior-stabilizing, fixed-bearing and mobile-bearing with the PCL retention. Methods 25 patients were selected for each kind of the prosthesis, and the inclusion criterion was based as the knee OA, good-excellent outcome after TKA, the flexion of the knee beyond 90?, and more than one year follow-up. The average age of these patients was 68 years with a range of 63 to 77 years, which involved 32 males and 43 females. The average preoperative knee flexion in the three groups were 77.8??15.1?, 80.1??12.9? and 76.4??12.7? respectively. The roentgenograms were taken both at the knee extension and maximum flexion, then the femur translation and the knee flexion were measured. Results The difference of the knee flexion among three groups preoperatively was of no significance. The maximum postoperative knee flexion in the posterior stabilizing, fixed-bearing and mobile-bearing was 118.0??7.1?,108.7??7.9? and 100.2??8.3? respectively. The analysis of variance showed the difference was of significance (F=32.86, P=0.0001). The relative movement about the femoral prosthesis in the three groups were (6.3?2.5) mm, (1.2?4.6) mm and ( 4.7?3.7) mm respectively (the posterior movement was positive, and the anterior was negative). The difference was of significance(F=57.71, P=0.0001). The femoral antero-posterior translation was proved to have correlation with the maximum knee flexion. Conclusion The femoral translation among three groups are different in manner, accordingly, the maximum knee flexion was different too.

Objective To investigate the influence and clinical significance of knee lateral thrust gait to femorotibial angle and lateral joint space in the patients with knee varus deformity. Methods 44 patients (male 10, female 34; range 31-60 years old, mean 41 years old) with knee varus deformity and lateral thrust involved in this study. The femorotibial angle and lateral joint space were measured on the standing anteroposterior film (single-foot loading and double-feet loading) of knee in order to compare the changes of them. The double-feet loading film simulated the corresponding relationship between thighbone and tibiae at double-support time, as early knee lateral thrust. The single-foot loading film simulated the corresponding relationship between thighbone and tibiae at single-support time, as late knee lateral thrust. The changes of femorotibial angle and lateral joint space in the two positions showed the changes of corresponding relation between thighbone and tibiae during knee lateral thrust. Results The mean femorotibial angle was 188.50??4.48? and 185.50??4.46? at the time of single-foot loading and double-feet loading respectively. It indicated that the femorotibial angle was increasing at the time of single-foot loading. The mean width of lateral joint space was (9.92?0.86) mm and (7.70?0.78) mm at the time of single-foot loading and double-feet loading respectively. It demonstrated that lateral joint space was widening more at the time of single-foot loading. The result suggested the lateral thrust of knee led to these changes. The increasing of femorotibial angle meant an increase of knee adduction moment during gait. The increasing of lateral joint space led to lateral structures chronic instability. The increased knee adduction moment and lateral structures chronic instability were the important mechanisms for degeneration of knee medial department. Conclusion The knee lateral thrust gait results in the augments of femorotibial angle and lateral joint space. These lead to the increase of the load on knee medial compartment, lateral structures chronic instability and varus deformity increasing. Lateral thrust might cause aggravation of knee varus and gonarthrosis at knee medial compartment.

[Objective]To analyze the reasons of complications in high tibial valgus osteotomy in the varus osteoarthritic knee and its management.[Method]We studied the results of valgus-producing high tibial osteotomies in patients who had medial unicompartmental osteoarthritis and varus malalignment.We performed the operation for 126 patients from January 2000 to October 2004.Twenty-one patients had complications,including four men and seventeen women,with average age of 61 years(ranged:48～64 years).The femorotibial angle was measured on the standing anteroposterior film of knee preoperatively in order to get high accuracy in preoperative planning.A lateral closing-wedge osteotomy was performed,the osteotomy site was stabilized by Giebel blade plate or stepped staple.[Result]The mean duration of follow-up was 7.5 months(ranged,6 to 12 months).There were twenty-three complications(21 patients,16.7%):tibial fracture in four cases,deep-vein thrombosis in five cases,peroneal nerve palsy in three cases,recurrence of varus deformity in six cases,internal fixation failure in four cases(recurrence of varus deformity developed in two patients),a superficial wound infection developed in one patient.[Conclusion]To reduce the incidence of complications in high tibial valgus osteotomy,we should make familiarication with anantomy and take more accuracy in preoperative planning,improve surgical skill as well as appropriate perioperative management.

Objective To evaluation high tibial osteotomy combined with anteromedial transfer of the distal fragment for the treatment of medial and patellofemoral compartmental osteoarthritis of the varus knee. Methods High tibial osteotomy was performed in 30 knees of 24 patients with medial and patellofemoral compartmental osteoarthritis of the varus knee, which was combined with anteromedial transfer of the distal fragment. The patients included 5 males (7 knees), 19 females (23 knees), with the mean age 53 years (range, 49-55 years). All patients were followed-up with footprints to assess the foot progression angle preoperatively and at 6 months to 2 years after the osteotomy. Tibial torsion of these subjects was measured by computerized tomography preoperatively and after the osteotomy. The statistical evaluation was carried out by the paired t test. Results The foot progression angle was 8.95??2.99? preoperatively, and -2.23??4.11? postoperatively during walking. The tibial torsion was 33.77??8.12? preoperatively and 21.27??8.48? after the osteotomy. The statistical evaluation showed foot progression angle and tibial torsion preoperative were significant difference from those postoperative (P 0.05). This result revealed that the decrease of foot progression angle was equal with the decrease of tibial torsion postoperatively. Conclusion High tibial osteotomy combined with anteromedial transfer of the distal fragment may be the effective method for medial and patellofemoral compartmental osteoarthritis of the knee, but it would cause calf and foot internal rotation. The change of foot progression angle and tibial torsion can influence the effect of high tibial osteotomy. The magnitude of anteromedial transfer of the tibial tubercle must be individualized and be devised preoperatively. It is important to evaluate patellofemoral malalignment and to measure the magnitude of tibial internal rotation in operation.
