RESUMEN
Objective@#To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) .@*Methods@#The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored.@*Results@#①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ2=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ2=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ2=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ2=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) .@*Conclusions@#HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

RESUMEN
Objective@#To evaluate the outcomes of human leukocyte antigen (HLA) matched unrelated donor hematopoietic stem cell transplantation (MUD-HSCT) for adult acute myeloid leukemia (AML) in a single center.@*Methods@#Consecutive adult AML who received MUD-HSCT in our center from January 2008 to April 2017 were studied retrospectively, comparing with patients undergoing matched sibling donor (MSD) -HSCT in the same period. The rates of overall survival (OS) , disease free survival (DFS) , relapse, non-relapse mortality (NRM) , engraftment, acute and chronic graft-versus-host disease (aGVHD and cGVHD) were analyzed.@*Results@#A total of 247 consecutive cases were enrolled, including 46 patients with MUD-HSCT and 201 with MSD-HSCT. All the patients experienced neutrophil engraftment except for one patient who died early in the MSD group, but the median day of engraftment was longer in the MUD group (15.0 vs 14.0, P=0.017) . The accumulative engraftment rate of platelet was comparable between the two groups (93.5%vs 98.0%, P=0.128) . The accumulative incidences of aGVHD (50.0%vs 46.3%, P=0.421) and cGVHD (37.8%vs 43.0%, P=0.581) were not statistically different between the two groups. Compared with the MSD group, the accumulative NRM rate at+36 months after transplantation was significantly higher in the MUD group (22.0%vs 10.4%, P=0.049) , while the relapse rate was not statistical difference (20.5 vs 28.3%, P=0.189) . Both the 3-year OS (61.6%vs 63.3%, P=0.867) and DFS (57.5%vs 61.6%, P=0.760) were comparable between the two groups. Four independent risk factors were confirmed by the multivariate analysis: patient age ≥45 years old, CR2 or NR before transplantation, a history of extramedullary infiltration and the occurrence of grade Ⅲ-Ⅳ aGVHD. No statistical differences were demonstrated in the survival rate between MUD-and MSD-HSCT in different subgroups.@*Conclusions@#The outcomes, such as GVHD, relapse, OS and DFS, were comparable between MUD-and MSD-HSCT for adult AML, but higher incidence of NRM and longer time to neutrophil engraftment in the MUD group. MUD-HSCT is practical and feasible for adult AML who are lack of MSD.
RESUMEN
Objective@#To explore the effectiveness of a novel GVHD prophylaxis regimen containing low-dose anti-T lymphocyte globulin (ATG) in patients undergoing peripheral blood stem cell transplantation (PBSCT) from HLA-matched sibling donors (MSD) given both the patients and donors were aged over forty years old.@*Methods@#From March 2013 to April 2017, 98 patients with hematologic malignancies were enrolled in the study. Standard GVHD prophylaxis consisted of the administration of cyclosporine A/tacrolimus and a short course of methotrexate. In ATG group, 43 patients received low-dose rabbit ATG (Sanofi, 1.5 mg/kg per day for 3 consecutive days) before PBSCT. A retrospective matched-pair analysis was performed and 55 matched controls were available. The therapeutic process and clinical outcome were retrospectively analyzed.@*Results@#①Neutrophil engraftment was achieved earlier in ATG group than the control one [13(11-17)d vs 14(12-24)d, P=0.001]. The time to platelet engraftment was similar between the two groups [14(11-43)d vs 15(11-42)d, P=0.071]. ②The cumulative incidence of aGVHD was significantly lower in ATG group [25.6% (95%CI 13.7%-39.3%) vs 49.1% (95%CI 35.2%-61.6%), P=0.018]. The incidences of grade Ⅱ-Ⅳ aGVHD [18.6% (95%CI 8.6%-31.5%) vs 23.6% (95%CI 13.4%-35.6%), P=0.509] and cGVHD [49.6% (95% CI 31.6%-65.3%) vs 56.4% (95% CI 41.4%-69.0%), P=0.221] were not significantly different between the two groups. ③The 1-year cumulative incidence of CMV viremia was similar between the two groups [21.1%(95%CI 10.3%-34.5%) vs 31.1% (95%CI 18.8%-44.2%), P=0.429]. ④The cumulative incidences of disease relapse [24.0%(95%CI 11.5%-38.9%) vs 24.0% (95% CI 12.1%-38.2%), P=0.608), non-relapse mortality [10.2% (95% CI 3.1%-22.1%) vs 21.6% (95% CI 9.4%-37.0%), P=0.411] and DFS [65.8% (95%CI 50.3%-81.3%) vs 54.4% (95%CI 37.7%-71.1%), P=0.955] were comparable between the two groups. 2-year overall survival (OS) was significantly better in ATG group than the control one [83.8% (95% CI 71.8%-90.0%) vs 58.0% (95% CI 42.2%-73.9%), P=0.019].@*Conclusion@#The addition of low-dose ATG decreased the incidence of aGVHD and improved OS. The incidences of viral infections and disease relapse remained to be similar between the two groups. These results suggested that elderly patients undergoing MSD-PBSCT may benefit from this low-dose ATG containing GVHD prophylaxis regimen.
RESUMEN
Objective@#To compare eficacy and safety of porcine antihuman lymphocyte immunoglobulin (pALG) and rabbit antithymocyte immunoglobulin (rATG) as a part of alternative donor allogeneic hematopoietic stem cell transplantation (AD allo-HSCT) for severe aplastic anemia (SAA).@*Methods@#The clinical data of 46 SAA patients received AD allo-HSCT from January 2006 to November 2016 were retrospectively analyzed. The cohort of patients were divided into two groups based on rATG or pALG as a part of conditioning regimen to compare implantation rate, transplantation related complications and outcome.@*Results@#In rATG group 30 patients achieved ANC reconstitution, 27 patients achieved PLT reconstitution. In pALG group all 16 patients achieved ANC and PLT reconstitutions. There were no significant differences between the two groups in terms of acute graft-versus-host disease (aGVHD) (P=0.475), Ⅲ-Ⅳ grade aGVHD (P=0.876), chronic GVHD (cGVHD) (P=0.309), extensive cGVHD (P=0.687), graft rejection (GR) (P=0.928), bloodstream infection (P=0.443), invasive fungal disease (P=0.829), cytomegalovirus viremia (P=0.095) respectively. Prospective 5-year overall survival (OS) in rATG and pALG groups were (75.1±8.2)% and (53.6±13.3)% with median follow-up of 14(2-102) and 23(4-63) months, respectively (P=0.190).@*Conclusion@#As a part of conditioning regimen, pALG could achieve similar efficacy as rATG, without increasing the incidences of transplantation complications such as GVHD, GR and infection, in the setting of AD allo-HSCT for SAA patients.
RESUMEN
Objective@#To evaluate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for the treatment of acute myeloid leukemia (AML) patients with FLT3-ITD mutation.@*Methods@#From September 2008 to December 2016, 40 AML patients with FLT3-ITD mutation were enrolled in the study. The therapeutic process, outcomes and prognostic factors were retrospectively analyzed.@*Results@#The median of WBC at initial diagnosis was 35.0 (range 1.7-185.0) ×109/L. The median course number of chemotherapy was 4 (range 2-7). At the time of transplantation, 34 patients were at the first complete remission (CR1) stage, and the other 6 ones were non-remission after chemotherapy. 24 patients received allogeneic transplants from an HLA-matched sibling donor, 7 cases from a HLA-matched unrelated donor, the remaining 9 ones received allograft from a haploidentical donor. The rate of 3-year overall survival (OS) and disease free survival (DFS) in all patients were both 74.3% (95% CI 60.4%-88.2%). The 3-year cumulative incidences of disease relapse and non-relapse mortality were 7.5% (95%CI 1.9%-18.4%) and 18.2% (95% CI 7.9%-32.0%), respectively. More than one course of chemotherapy before achieving CR1 and the occurrence of acute GVHD after transplantation were associated with poor outcome in terms of OS and DFS. The relapse rates were significantly lower in patients receiving transplantation at CR1 stage [0 vs 50.0% (95%CI 77.7%-82.9%) , P<0.001] and achieving CR1 after one course induction therapy [0 vs 16.7% (95%CI 3.9%-37.3%) , P=0.020].@*Conclusions@#Allo-HSCT was an efficient approach for AML patients with FLT3-ITD mutation. Patients obtained better survival, especially for those achieving CR after one course induction therapy and receiving transplantation at CR1 stage.
RESUMEN
Objective@#To evaluate the prognostic significance of early phase full donor chimerism (FDC) after myeloablative allogeneic peripheral blood stem cell transplantation (allo-PBSCT).@*Methods@#The clinical data of 72 hematological patients received myeloablative allo-PBSCT from Feb. 2016 to Jul. 2017 were analyzed retrospectively. The median age was 36.5 years (range 4-59), 44 were males and 28 females. Of the donors, there were 35 HLA matched sibling donors, 27 haploidentical donors and 10 unrelated donors. Polymerase chain reaction amplification of short tandem repeat sequence (PCR-STR) was used to detect donor cell chimerism (DC) rate of recipient bone marrow at one, two and three months after transplantation.@*Results@#The median follow-up was 462 d (range: 47-805 d), 55 cases were still alive, and 45 cases were disease-free survival (DFS) at the end of follow-up. The 2-year overall survival (OS) and DFS were (68.9±7.7)% and (59.5±6.3)%, respectively. A number of 16 cases underwent relapses, with 2-year cumulative incidence of (24.1±5.3)%. The median time of recurrence was 157(32-374) d. Forty cases (55.6%) developed acute graft-versus-host diseases (aGVHD), with median time of 35.5 (13-90) d. Chronic GVHD (cGVHD) occurred in 23 patients (31.9%), with median time of 169 (94-475) d. Univariate analysis found the following factors were not related to OS, DFS or relapse rate (RR), including age, sex, blood type and sex of donor-recipient, occurrence of aGVHD and cGVHD. The OS and DFS in cases reached FDC and no FDC at two months after transplantation were (85.2±6.9)% vs (66.1±7.7)% (P=0.051) and (76.7±7.7)% vs (48.9±8.1)% (P=0.021), respectively. The RR rate in FDC group was lower than that in no FDC group [(16.6±6.8)% vs (30.4±7.8)%, P=0.187, respectively].@*Conclusion@#The present study confirmed the important value for predicting the prognosis with whether or not the patients reached FDC at the early phase after allo-PBSCT. The OS and DFS in cases with FDC at two months after transplantation were significantly higher than those of no FDC patients.

RESUMEN
<p><b>OBJECTIVE</b>To analyze the common hemorrhage sites during laparoscopic rectal cancer surgery in order to take reasonable prevention and management.</p><p><b>METHODS</b>Clinical data of 355 rectal cancer patients who underwent laparoscopic total mesorectal excision in Shanxi Provincial People's Hospital from January 2012 to December 2014 were retrospectively analyzed. Common bleeding sites, blood loss, and hemostasis time were recorded. According to the date of operation, patients were divided into 2012 group (91 cases), 2013 group (122 cases) and 2014 group(142 cases). Hemorrhage rates were compared among three groups.</p><p><b>RESULTS</b>No significant differences were observed in the baseline data among the three groups(all P>0.05). The location in the order of the hemorrhage rate from high to low was seminal vesicle tail (63.0%, 131/208), inferior mesenteric vessels (27.3%, 97/355), Toldt's space (24.2%, 86/355), lateral rectal ligaments (12.1%, 43/355) and post-rectal spatial (8.2%, 29/355). According to the blood loss, post-rectal spatial[(14.1±7.1) ml], inferior mesenteric vessels [(12.7±6.1) ml] and seminal vesicle tail [(12.4±6.5) ml] were ranked in top three. The hemostasis time of seminal vesicle tail [(11.5±6.6) minutes] and post rectal spatial [(10.3±7.8) minutes] was longer than the others. Compared with 2012 group, shorter operative time [(205±50) minutes vs. (235±55) minutes, t=4.296, P=0.001], less blood loss [(35±19) ml vs. (81±24) ml, t=16.243, P=0.001] and lower hemorrhage rate [Toldt's space: 7.7%(11/142) vs. 39.6%(36/91), inferior mesenteric vessels: 9.2%(13/142) vs. 44.0%(40/91), post-rectal spatial: 0.7%(1/142) vs. 15.4%(14/91), lateral rectal ligaments: 2.1%(3/142) vs. 29.7%(27/91) and seminal vesicle tail: 50.6%(41/81) vs. 79.6%(43/54)] were found in 2014 group. The decline of hemorrhage rate in seminal vesicle tail was the slowest (χ=11.792, P=0.003).</p><p><b>CONCLUSIONS</b>The common hemorrhage sites during the laparoscopic rectal cancer surgery are inferior mesenteric vessels, Toldt's space, lateral rectal ligaments, post rectal spatial and seminal vesicle tail. Appropriate preventive measures can ameliorate the intraoperative bleeding significantly, however, more attention should be paid to the seminal vesicle tail during operation because of its higher hemorrhage rate, more blood loss and difficult hemostasis.</p>
RESUMEN
Objective@#To evaluate the outcomes and prognostic factors of patients with refractory and relapsed acute myeloid leukemia (AML) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) .@*Methods@#The overall survival (OS) , disease free survival (DFS) , acute and chronic graft-versus-host disease (GVHD) , relapse rate (RR) , transplantation related mortality (TRM) and their related risk factors were analyzed retrospectively.@*Results@#All the patients (median age 35 years, range 6 to 58) received myeloablative conditioning regimens. All patients had successful engraftment, and the median time of neutrophils engraftment was 14 days (range 9 to 25) . Of the patients who survived more than 100 days, the accumulative incidence of grade Ⅱ-Ⅳ acute GVHD and chronic GVHD (cGVHD) were 27.3% (95%CI 18.9%-36.3%) , 33.9% (95%CI 24.6%-43.5%) , respectively. Meanwhile, the accumulative incidence of extensive cGVHD was 9.3% (95%CI 4.5%-16.1%) . The 3-year OS, DFS, RR, and TRM was 45.0% (95%CI 34.6%-55.4%) , 45.0% (95%CI 34.8%-55.2%) , 36.6% (95%CI 26.9%-46.4%) and 19.7% (95%CI 12.4%-28.3%) respectively. Multivariate analysis revealed four independent risk factors: non remission status before transplantation[P=0.009, HR=2.21 (95%CI 1.22-4.04) ], WBC at diagnosis>50×109/L[P=0.024, HR=2.11 (95%CI 1.11-4.02) ], donor age>35 years [P=0.031, HR=1.96 (95%CI 1.06-3.60) ]and without cGVHD[P=0.008, HR=0.38 (95%CI 0.18-0.78) ]. According to the risk factors before transplantation (non remission status, WBC at diagnosis>50×109/L, donor age>35 years) , we then defined three subgroups with striking different OS at 3 years: no adverse factor (75.0%) ; one adverse factor (46.9%) ; two or three adverse factors (15.4%) (χ2=26.873, P<0.001) .@*Conclusion@#Allo-HSCT is a promising and safe choice for patients with refractory and relapsed AML and relapse is the major cause of the transplantation failure. Disease status before transplantation, donor age, WBC at diagnosis and cGVHD are confirmed as prognostic factors for these patients who received allo-HSCT.

<p><b>OBJECTIVE</b>To clarify the role of endothelial cells (ECs) injury induced by anti-endothelial cell antibody (AECA) in allogeneic hematopoietic stem cell transplantation (allo-HSCT).</p><p><b>METHODS</b>Serum immunoglobulin (IgG) from allo-HSCT recipients were purified and incubated with human umbilical vein vascular endothelium (HUVEC) in vitro, then the functional changes and cell apoptosis were tested.</p><p><b>RESULTS</b>After incubation with AECA positive IgG, soluble adhesion molecules significantly elevated in culture supernatant. When concentration of IgG was 160, 320, and 640 μg/ml, concentrations of soluble intercellular adhesion molecule-1 in supernatant were statistically higher in AECA positive groups [(117.10 ± 12.82) vs (78.17 ± 4.90) pg/ml, (151.30 ± 15.35) vs (89.46 ± 6.02) pg/ml, (239.00 ± 32.53) vs (127.80 ± 13.86) pg/ml, P<0.01)]. When concentration of IgG was 40, 80, 160, 320, and 640 μg/ml, concentrations of soluble vascular cell adhesion molecule-1 in supernatant were also statistically higher in AECA positive groups [(38.51 ± 3.76) vs (24.78 ± 2.59) pg/ml, (61.34 ± 6.99) vs (38.20 ± 3.17) pg/ml, (135.60 ± 24.46) vs (63.73 ± 5.08) pg/ml, (221.30 ± 29.40) vs (112.80 ± 8.91) pg/ml, (420.90 ± 31.70) vs (224.40 ± 20.79) pg/ml, P<0.01]. Clotting activity factors also elevated in culture supernatant after incubation with AECA positive IgG. When concentration of IgG was 80, 160, 320, and 640 μg/ml, concentrations of von Willebrand factor were statistically higher in AECA positive groups [(19.51 ± 0.72) vs (17.17 ± 0.60) ng/ml, P=0.0193; (22.97 ± 1.18) vs (18.27 ± 0.61) ng/ml, (26.40 ± 1.54) vs (19.53 ± 0.70) ng/ml, (34.35 ± 1.60) vs (23.81 ± 0.92) ng/ml, P<0.01]. When concentration of IgG was 320 and 640 μg/ml, concentrations of thrombomodulin were statistically higher in AECA positive groups [(57.50 ± 4.50) vs (40.31 ± 4.39) pg/ml, P=0.0132; (59.18 ± 4.11) vs (38.84 ± 5.16) pg/ml, P<0.01].

BACKGROUND:Muscle atrophy and weakness exist around the knee joint of patients with knee osteoarthritis, comprehensive treatment combined with training muscle power around knee joint can obviously relieve symptoms and restore muscle power around the knee joint. OBJECTIVE:To test the relationship between muscle function around the knee joint and the knee joint function with isokinetic muscle strength test before and after comprehensive treatment of knee osteoarthritis, and to investigate the pathological mechanisms of knee osteoarthritis in order to provide basis for the clinical rehabilitation and treatment. METHODS:We screened out 30 subjects with unilateral knee osteoarthritis (stage Ⅱ and Ⅲ). Hospital for Special Surgery was used to evaluate the knee function, and visual analogue scale score was used to assess the patient pain. The knee muscle function of knee osteoarthritis patients was measured before treatment;the patients with knee osteoarthritis at stage Ⅱ and Ⅲ received comprehensive treatment for at least 1 month (active quadriceps isometric muscle strengthening exercises, oral celecoxib capsules combined with intra-articular injection of sodium hyaluronate), and knee muscle function was measured after treatment. Hospital for Special Surgery and the visual analogue scale score were evaluated during fol ow-up period. RESULTS AND CONCLUSION:Compared with the healthy side, the muscle power of the affected side of the patients with knee osteoarthritis was decreased when the flexion and extension muscle peak torque and work volume tested at 60 (°)/s and 180 (°)/s (P between affected side and healthy side after treatment (P>0.05). There was no significant difference in the peak torque ratio of quadriceps and hamstring measured at 60 (°)/s in the knee osteoarthritis patients before and after treatment (P>0.05), and there was significant difference measured at 180 (°)/s (P<0.05). Knee osteoarthritis patients have decreased muscle strength around the knee joint, and the comprehensive treatment of muscle functional training combined with effective pain relief and nutrition joint drugs can significantly relieve symptoms, improve muscle strength and restore knee function.
RESUMEN
Objective To assess the clinical efficacy and safety of proton pump inhibitors (PPI)for preventing recurrence of non-steroidal anti-inflammatory drugs (NSAIDs)-indueed upper gastrointestinal ulcers using meta-analysis. Methods Mono- or multicenter randomized controlled clinical trials related to NSAIDs-indueed ulcers were retrieved from database of China Biological Medicine and Medline from 1966 to 2007. The data were analyzed by RevMan 4. 2 software using random or fixed effects model. Results Ten randomized controlled trials including 3361 patients were included, The recta-analysis revealed that PPI treatment significantly reduced the recurrent rate of NSAIDs-associated ulcers (8. 7%) in comparison with controls (17. 2%, P = 0. 03). Those who received esomeprazole (4. 4%) or lansoprazole (18. 0%) had a low recurrence of peptic ulcers compared with controls (14.7% or 28.7%, P value= 0.01 or 0.05). But there was no significant differencebetween omeprazole and controls (P= 0. 16). The recurrence of NSAIDs-associated ulcers in patients treated with esomeprazole 20 mg or 40 mg and tansoprazole 15 mg were 4.4%, 4.3% and 19.7 % respectively. The stratify analysis showed that PPI therapy could effectively reduce recurrentce of non-selective NSAIDs-induced ulcer (P= 0. 009), but failed to selective cyclooxygenase (COX)-2 inhibitor induced ulcer. No severe adverse reactions were found in PPI groups. Conclusion PPI is effective and safe in prevention of NSAIDs-related ulcers without discontinuation of NSAIDs.
RESUMEN
[Objective]To analyze the causes of perioperative periprothetic fracture with hip arthroplasty and discuss the prevention and treatment of the fracture.[Method]18 of 640 THR cases occurred femoral fracture from July 1995 to August 2006,11 with intraoperative fracture and 7 with postoperative fracture,12 were and 6 female,the mean age 68 years(range:51 to 79 years).According to AAOS'standard,18 cases were divided into 6 types:1 of I type,6 of II type,4 of III type,4 of IVa type,2 of IVb type,1 of V type and 2 of VI type.10 of 11 cases of intraoprative fracture were operated immediately with internal fixation,and one of II type was treated with conservative method.4 of 7 cases of postoperative fracture were operated with open reduction and internal fixation in two weeks,2 cases with loosen stem were operated by revision hip,and one of V type was treated with conservative method because of other disease.[Result]The mean followed up perioid were 15.2 months(rang:6 to 42 months),15 fractures united,2 delayed united and 1 dead after 8 months postoperatively.The average scores were 80 according to Harris'standard(range:67 to 92).[Conclusion]Violence、abnormal of femur cannal、osteoprosis and bigger prothesis are the main causes of intraoperatively peri-prothetic femur fracture after THA,and loosening、 osteoperosis and outside injury are the main causes of postoperatively periprothetic femoral fracture,different treatment should be used according to the different types.
RESUMEN
[Objective]To study the reason of loosening prothesis by observing the interface membranes harvested during the hip revision operation.[Method]Thirty eight specimens of interface membranes around the loosening prothesis were harvested from thirty eight patients who underwent the revision of total hip replacement.All the specimens were underwent outer observation,light and scanning electronic microscopic observation.[Result]All the gap of the loosening prothesis were filled with interface membranes with different thickness.A large number of the foreign pelletand bone pieces were found under scanning electronic microscope.[Conclusion]Interface membranes growed and filled in the gap between the loosening prothesis and bone(or bone cement).The wear debris stimulated the interface membrane to release bone resorption factors which caused the prothesis loosening,and the more loosening,the more large gap appeared,and the more resorption factors released from the interface membranes due to the debris stimulating,which formed vicious circle.Cutting the link of the circle could decrease the loosening rates.
RESUMEN
<p><b>OBJECTIVE</b>To observe clinical efficacy of intra-articular injection of Sodium hyaluronate (SH) accompanied with external application of Sanhua ointment (SHO) for knee osteoarthritis.</p><p><b>METHODS</b>One hundred and twelve patients with osteoarthritis were randomly divided into two groups, Group I was treated with SH and Group II was treated with SH plus SHO. The entire condition of knee joint in the two groups were compared before and after treatment according to Lysholm's function scoring.</p><p><b>RESULTS</b>The functional score in the two groups at the 2nd week, 5th week, 3rd month and end of 1st year of the treatment course were significantly higher than that before treatment (P < 0.05), and the scores continuously increased within the first 3 months of treatment. Comparison of scores between the two groups showed that scores in Group II was significantly higher than those in Group I at the corresponding period. The total effective rate after 1 year treatment in Group lI was higher than that in Group II (81.5% vs 96.6%, P < 0.05). In Group II , the initial time of symptom improving was earlier and the adverse effect disappeared more quickly than those in Group I markedly.</p><p><b>CONCLUSION</b>The efficacy of combined therapy of intra-articular injection of SH and SHO for knee osteoarthritis was superior to that of intra-articular injection of SH only.</p>
