OBJECTIVE:To compare the clinical efficacy and safety of rivaroxaban and low molecular weight heparin calcium (LMWHA)in the prevention of deep venous thrombosis(DVT)after total hip arthroplasty(THA). METHODS:A total of 100 THA patients selected from orthopedics department of our hospital as research objects were divided into control group and observa-tion group according to random number table,with 50 cases in each group. Control group was treated with LMWHA injection 0.4 mL subcutaneously,qd;observation group was given Rivaroxaban tablet 10 mg orally,qd. Both groups received treatment on the first day after surgery,for consecutive 14 d. Coagulation indexes(PT,APTT,Fib,TT,D-D),VAS score,the incidence of DVT and PE were observed in 2 groups. The postoperative bleeding volume and ADR as hematoma and gastrointestinal bleeding were compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in coagulation indexes or VAS scores between 2 groups(P>0.05). After treatment,PT,APTT,TT and D-D levels,VAS scores of 2 groups were decreased sig-nificantly,while Fib levels were increased significantly;VAS score of observation group was significantly lower than that of con-trol group,with statistical significance(P<0.05). There was no statistical significance in coagulation indexes between 2 groups (P>0.05). The incidence of DVT and PE in observation group were 8.00% and 7.50% ,which were significantly lower than 12.00% and 4.00% of control group,with no statistical significance(P>0.05). The postoperative bleeding volume of observation group was(298.31±52.18)mL,which was significantly lower than(327.40±54.20)mL of control group,with statistical signifi-cance(P<0.05). There was no statistical significance in the incidence of hematoma or gastrointestinal bleeding between 2 groups (P>0.05). CONCLUSIONS:Rivaroxaban and LMWHA can significantly improve coagulation state,prevent the generation of DVT after THA. While rivaroxaban is better in shortening pain time without increasing the risk of ADR.

It is discussed in this paper the origins and pathogenesis of treating senile disease from spleen in TCM,and the relationship between various methods of invigorating the spleen and senile deficiency syndromes.It has been proposed that the therapy principles of invigorating qi and spleen,stimulating the appetite to awake the splee,primering blood to go back to the spleen,dehumidification to activate spleen-energy,warming the kidney and spleen,dispersing the depressed liver-energy to belifit the spleen,going on dieting to belifit the spleen and clearing away heart-fire to support spleen etc.are used to prevent and cure senile diseases.It also listed the corresponding treatment prescriptions for the elderly patients.It provides a theoretical basis for treatment of senile diseases from the governance of spleen.And it provided a realistic basis and the implementation of the method for the prevention and treatment of elderly patient's deficiency aging.

Objective:To discuss the result of treating valgus or varus knee deformity with fixator assist nailing (FAN)technique and distal femur osteotomy(DFO).Methods:In this retrospective study,14 patients with 17 limbs,12 valgus and 5 varus knee deformity were treated with DFO and FAN.The aver-age age of the patients was 23 (17-44)years .The unilateral external fixator was mounted on the lateral side of femur,the minimal invasive distal femoral osteotomy was performed.After the deformity was cor-rected,the intramedully nail was inserted to fix the femur.None of the patients need bone autograft.The preoperation and postoperation lateral distal femur angle (LDFA ),mechanical axis deviation (MAD ) and range of motion (ROM)were measured and analyzed.Results:All the 14 patients were followed-up for 12 -72 months (average 34 months).The osteotomy site united in 3 -5 months (average 3.5 months)post-operatively.According to Paley’s functional scores,12 patients were excellent,2 patients were good.We achieved desired postoperative MAD (from medial 15 mm to lateral 10 mm)in 15 limbs of 12 patients.The LDFA in 1 1 limbs was corrected to normal (84°-90°).The ROM was not signifi-cantly changed before and after operation in the both groups.No infection or neuro-vascular injury oc-curred.Conclusion:The FAN technique is an effective method to treat valgus knee or varus knee de-formity in young patients with DFO.

Objective To explore the application value of thromboelastography(TEG)in perioperative evaluation of benign pros-tatic hyperplasia(BPH) patients treated with anticoagulants .Methods To retrospective analyze the intraoperative bleeding ,postop-erative bleeding and transfusion treatment of 120 patients with BPH surgery ,who were treated with anticoagulants .The results of TEG detection and coagulation function test were compared .Results There was no patients with significant intraoperative bleed-ing ,including 40 cases of bleeding after surgery ,80 cases of patients with no bleeding .In patients of bleeding ,there were 32 benign prostatic hyperplasia patients(80 .00% )with low coagulation function detected by TEG detection ,and 18(45 .00% ) with low coagu-lation function detected by routine coagulation function test .The difference of detection rates was statistical significant between the two methods(χ2 =12 .709 ,P=0 .002) .In patients of non-bleeding ,there were 76 benign prostatic hyperplasia patients(95 .00% ) with non-low coagulation function detected by TEG detection ,and 67(83 .75% )with non-low coagulation function detected by rou-tine coagulation function test .The difference in detection rate was significant between the two methods(χ2 =6 .679 ,P=0 .022) . Conclusion TEG could effectively evaluated postoperative bleeding in BPH patients ,guide postoperative transfusion therapy ,which is better than routine coagulation function test .

Objective To investigate the susceptibility ofepidermal cells to ultraviolet A(UVA)-induced apoptosis in dopachrome tautomerase knockout Dct~(-/-) mice versus wildtype C57BL/6J mice.Methods High titer of anti-Ro/SSA-positive sera collected from three patients with SLE and typical cutaneous phntosensitivity were intraperitoneally injected into both Dct~(-/-) and wildtype mice,which were then chronically exposed to UVA irradiation at a single dose of 10 J/cm~2 three times a week for two weeks.Then,UVA-irradiated tail skin was excised from each mouse,embedded with paraffin,cut into 4 to 5-μm sections followed by hematoxylin/eosin staining and terminal deoxynucleotidyl transferase nick end labeling(TUNEL),respectively,for the counting of sunburn cells(SBC) and apoptotie cells.Results After chronic UVA exposure,the number of SBC and TUNEL-positive cells per 100 epithelial cells was significantly higher in serum-injected Dct~(-/-) mice than in serum-injected wildtype mice(14±1.0 vs 7±-0.6,62±2.7 vs 30 ±1.6,both P<0.05).A significant decrease was also observed in the number of SBC (6 ±0.9 per 1 00 epithelial cells)and TUNEL-positive cells (42±2.5 per 100 epithelial cells)in uninjected Dct~(-/-) mice compared with those of serum-injcoted Dct~(-/-) mice(both P<0.05).Conclusions The deficiency of Dct gene increases the susceptibility of epidermal cells to UVA-induced apoptosis under the presence of anti-Ro/SSA antibody,which potentially contributes to the develop-ment of anti-Ro/SSA antibody-mediated photosensitivity in SLE.

ObjectiveTo evaluate the effectiveness of correction of posttraumatic flexion contracture of knee(FCK) using Ilizarov technique.MethodsSix male patients with posttraumatic FCK,aging from 9 to 43 years(mean,24.5 years),treated by using Ilizarov technique from January 2006 to December 2010,were retrospectively analyzed.The preoperative flexion deformity of knee ranged from 35° to 85° (mean,47.6°),and the range of motion ranged from 0° to 70° (mean,15.8°).Among them,five patients had old fracture of knee joint combined with equinus foot deformity (deformity ranging from 25° to 37°,with an average of 31.8°); one patient had femoral supracondylar fracture.We used circular external fixator to correct the FCK and equinus foot deformity gradually,the knee arthrodesis operation was performed in 4 patients because of the damaged hone structure and poor soft tissue condition.ResultsAll patients were followed up for 12-22 months(mean,18 months).The flexion of knee joint was recoverd from preoperative 47.67°±18.63° to postoperative 9.33°±3.50°.Plantar flexion of ankle joint in five equinus foot deformity was recovered from preoperative 31.80°±4.65° to postoperative 3.00°±4.47°.The kuee joint was arthrodesised successfully in 4 patients and the other 2 patients got 30° and 75° ROM.All the patients can walk with a cane,and satisfied with the result of treatment.Pin-site infection was found in 4 patients and was controlled within two weeks.ConclusionIlizarov technique is an effective treatment method for posttraumatic FCK.Knee arthrodesis should be performed when patients had damaged bone structure and poor soft tissue condition.

BACKGROUND:No method is ideal for treating traumatic avascular necrosis of talus up to now.Extracorporeal shock wave therapy(ESWT)is a micro-traumatic,simple,and effective method to treat musculoskeletal diseases;however,the therapeutic effect on necrosis of talus needs to be further studied.OBJECTIVE:To evaluate the therapeutic effect of liquid-electric extracorporeal shock wave on traumatic avascular necrosis of talus,and to explore new treatments of traumatic avascular necrosis of talus METHODS:A total of 34 patients with traumatic avascular necrosis of talus were selected from the Affiliated Hospital of Medical College of Chinese Armed Police Force from September 2004 to June 2009.The patients were randomly divided into ESWT and control groups,with 17 patients per group All patients were treated with pain point positioning combined with surface X-ray localization,theworking voltage of 8-10 kV,energyflowdensity of 0.12-0.16mJ/mm2,impact frequency of 40-50 times/min,and impact of 800-1000 times,once a week,for 3-5 cycles.Pain was evaluated with VAS before and after treatment,function of ankle was evaluated with AOFAS standards,and MRI of ankle was re-checked at 18 months after treatment to compare necrotic area before and after treatment.RESULTS AND CONCLUSION:VAS pain,function of ankle,and necrotic area of ankle in the ESWT group were significantly improved compared to those in the control group at 18 months after treatment(P<0.01).Activity of one case in the control group was limited by severe pain due to traumatic arthritis in the first 15 weeks after ankle arthrodesis surgery.This suggested that significant effect and fewer complications,for treating traumatic avascular necrosis of talus.

Objective To evaluate the therapeutic effect of bone marrow mesenchymal stem cells (BMSC) transplantation via renal artery in treating experimental rats with adriamycin-induced chronic nephro -pathy.Methods A total of 50 male Sprague-Dawley (SD) rats were used as experimental animals.Two rats were used for the isolation and culture of BMSC.Twelve rats were designed as blank control group (group N);in other 36 rats adriamycin was injected through caudal vein to establish rat models of chronic nephropathy,these 36 rats were randomly and equally divided into three groups with 12 rats in each group:control group (group C,n=12),BMSC transplantation via renal artery group (group A,n=12),and BMSC transplantation via caudal vein group (group V,n=12).For the rats of group N,the same amount of normal saline was injected through caudal vein.Results At each observation point,the levels of blood urea nitrogen,serum creatinine,24 h urinary protein and 24 h urinary microprotein in group A,V and C were remarkably higher than those in group N (P＜0.01).One and two weeks after BMSC transplantation,the 24 h urinary microprotein level in group A was significantly lower than that in group C (P＜0.01);the serum creatinine level in group A was significantly lower than that in group C and group V (P＜0.01).One week after BMSC transplantation,both the 24 h urinary protein level and 24 h urinary microprotein level in group A were strikingly lower than those in group V (P＜0.01),but two weeks after BMSC transplantation these differences between group A and group V became not statistically significant.Conclusion BMSC transplantation via renal artery can improve cell-homing efficiency and improve the repair of damaged tissue as well.
