Objective To study the curative effectiveness of external iliac-popliteal artery artificial graft cross bypass in treating extensive arterial occlusion in unilateral lilac-femoral arteriosclerosis. Methods From Sep. 1999 to Oct. 2007, 39 elder patients were diagnosed as having extensive arterial occlusion in unilateral lilac-femoral arteriosclerosis by color Doppler ultrasonography, CTA or DSA. 25 patients (61.5%) had resting pain, 14 had ulcers or gangrenes in the toes. The average ankle-brachial index was 0. 19. Contralateral external iliac-popliteal artery artificial graft cross bypass surgeries were performed on 22 patients from left to right, the other 17 were from right to left. Results There were no perioperative death or amputation. The ankle-brachial index increased from 0 ～ 0. 41 ( preoperative ) to 0. 85 ～ 1.02(postoperative) ; the claudication distance increased from 15 ～ 60 m (preoperative) to 350 ～ 500 m or more than 500 m [ postoperatively at the speed of (100 ～ 120) m/min] ; The postoperative color Doppler uhrasonography showed the average velocity of the popliteal artery was 45 cm/s. In the anterior tibial artery or the posterior tibial artery, little blood flow was showed in preoperative color Doppler ultrasonography examination, the postoperative average blood flow velocity was 41 cm/s. 35 patients (89. 7% ) were followed up for an average of 3.4 years, with an accumulative patency rate of 85.7%. Four patients had amputation, the limb salvage rate is 88.6%. Conclusion External iliac-popliteal artery artificial graft cross bypass is effective in treating unilateral lilac-femoral arterial occlusion, particularly for aged patients with vital organ incompetence.

?AIM: To observe the efficacy of 25G vitrectomy for traumatic cataract.?METHODS:Retrospective analysis of 70 cases (70 eyes) of traumatic cataract treated by 25G vitrectomy with lensectomy from February 2013 to February 2015 in our hospital was made for the study.In the patients, there were 43 males ( 43 eyes ) , 27 females ( 27 eyes ) , aged from 22-51 years old with an average of 35.23±2.54 years, mean visual acuity was 0.10±0.03.They were all followed up for 6 -12mo postoperatively. Anterior segment, fundus, complications, best corrected visual acuity ( BCVA ) and intraocular pressure were observed during the follow - up. BCVA preoperatively, 1wk postoperatively, 1 mo postoperatively, 6mo postoperatively were compared.? RESULTS: All the patients underwent the surgery successfully, and visual acuity improved at different degrees. The differences of BCVA preoperatively compared with 1 and 6m postoperatively were all statistically significant ( P <0. 05 ). Postoperative complications:5 cases with corneal edema, 10 cases with ocular hypertension, 4 cases with ocular hypotension, 5 cases with retinal spotting.The symptoms improved after symptomatic and supportive treatment.? CONCLUSION: 25G vitrectomy with lensectomy is effective on treating traumatic cataract, with decreased operation risk, complications and improved visual acuity.

Objective To study the diagnostic value of anti-neutrophil cytoplasmic antibody (ANCA) detction in patients with systemic lupus erythematosus (SLE). Methods Indirect immunofluorescence (IIF) and Western blotting were applied to detecting the expression of sera ANCA, antinuclear antibody (ANA), anti-double-stranded DNA antibody, anti-SmithD1 antibody in 25 samples of control group and 106 samples of patients with SLE. Results ALL samples of control group showed negative; 47.2% (50/106) sera showed ANCA positive in patients with SLE,and all of them were peripheral nuclear pattern (pANCA). In ANCA positive group, the positive rate of ANA, anti-SmithD1 antibody and anti-ds-DNA antibody was respectively 100% (50/50), 82% (41/50) and 94% (47/50); in ANCA negative group, the positive rate was respectively 91.1% (51/56), 67.9% (38/56)and 50% (28/56). There were no statistical differences in positive rates of ANA and anti-SmithD1 antibody between ANCA positive and negative groups (both P＞0. 05), but there was in positive rates of anti-ds-DNA antibody (P＜0.01). ANCA positive rate was respectively 84.6% (44/52) and 11.1%(6/54) in active SLE group (n=52) and inactive SLE group (n=54) (P＜0.01). Conclusion The determined ANCA in patients with SLE is not correlative with ANA and anti-SmithD1 antibody, but positively relates to anti-double-stranded DNA antibody. The positive rate of ANCA in patients with active lupus is significantly higher than that in non-active lupus.

Objective To explore the effect of treadmill exercises on disuse osteoporosis and the media effect of OPG-RANKL-RANK system of osteoclast differentiation in the process.Methods Forty six-week-old male Sprague-Dawley rats were randomly divided into a normal control group,a disuse model group,a normal recovery group and an exercise recovery group,each of 10.The normal control group were sacrificed 4 weeks later without receiving any special treatment.The disuse model group were sacrificed after 4 weeks of tail suspension.The normal recovery group were sacrificed after 4 weeks of tail suspension and keeping quiet for 4 weeks.The exercise recovery group were sacrificed after 4 weeks of tail suspension and another 4 weeks of treadmill exercises.The indicators of bone mineral density (BMD),bone histomorphometry,bone tissue TRACP-5b staining,bone metabolism and cytokines related to the osteoclast differentiation OPG-RANKL-RANK system were tested immediately after the rats were sacrificed.Results The BMD,trabecular bone volume percentage (TBV),trabecular bone width (Tb.Wi),concentration of serum alkaline phosphatase (ALP) and the gene expression of bone marrow oculopneumoplethysmograph (OPG) of the disuse model goup were significantly lower than those of the normal control group (P＜0.01),while the trabecular bone spacing (Tb.Sp),average positive staining area percentage (APSAP) of tartrate-resistant acid phosphatase (TRACP)-5b,concentration of serum Ca2+ and TRACP-5b and the gene expression of bone marrow cytokines including RANKL,macrophage colony-stinulating factor (M-CSF),RANK,interleukin (IL)-6 and tumor necrosis factor (TNF)-α of the disuse model goup were significantly higher than those of the normal control group (P＜0.01).The BMD,TBV,Tb.Wi,concentration of serum ALP and the gene expression of bone marrow OPG of the exercise recovery group were significantly higher than those of the normal recovery group (P＜0.05 or P＜0.01).The Tb.Sp,APSAP,concentration of serum Ca2+ and TRACP-5b and the gene expression of RANKL,M-CSF,RANK,IL-6 and TNF-α of the exercise recovery group were significantly lower than those of the normal recovery group (P＜0.05 or P＜0.01).Conclusion The 4-week tail suspension can lead to disuse osteoporosis in rats.Treadmill exercise can promote the recovery of rats with the disuse osteoporosis.The occurrence of disuse osteoporosis and the effect of exercises on disuse osteoporosis were related with the expressing of OPG-RANKL-RANK system-related cytokines of osteoclast differentiation in bone marrow microenvironment.

BACKGROUND:The isokinetic muscle strength test system can quantitatively testtheshoulder flexor and extensormusclesand objectively analyze the relationship between size and balance of flexor and extensor.Therefore,itcould be used forstrength trainingmonitoringas wel asprediction and rehabilitation of sports injuries. OBJECTIVE:To understand shoulder flexor and extensor strength characteristics of adolescent softbal players, and find out shortcomings in the shoulder flexor and extensor strength to provide guidance for adolescent athletes’ strength trainingandpoint out possible sports injury risks caused by imbalanced strength. METHODS:ISOMED2000 isokinetic testing system(D&R,Germany)was employedto test theisokinetic strengthofshoulderflexor andextensor of12adolescentfemalesoftbal playersfromShanghaiSports University, China. RESULTS AND CONCLUSION:With the increase of test speed, the bilateral shoulder flexor and extensor peak torque, the flexor and extensor average power ratio,andthe flexor and extensor powers were reduced, but the flexor and extensor average power was on the rise. Under the same test speed,flexor and extensor peak torque, the flexor and extensor peak torque ratio, the flexor and extensor average power, the flexor and extensor average power ratio and the flexor powersof the throwing shoulderwere significantly larger thanthoseofthenon-throwingshoulder(P< 0.05), whiletheextensor peak torque and the extensor average powerof thethrowingand non-throwing shouldersshowedno significant differences (P> 0.05).Under the same test speed, bilateral shoulder homonymous flexor strength ratio was larger than that of the extensor, andthe extensor powerof the throwing shoulderwas less thanthatof the non-throwingshoulder.The ratio ofhomolateralshoulder flexor and extensor ranged from 70% to 80%. These results indicate that there is a significant difference betweentheflexor strength ofthebilateral shoulders inadolescent softbal players,but the bilateralextensor strengthis similar.Flexor fast strength and extensor maximum strengthof the throwing shoulderare lower. Besides, the isokinetic muscle strength test system canbe used toevaluate the flexor and extensor strengthinadolescent softbal athletes,based on whichcoachescangivetargetedstrength traininginadolescent softbal athletes.
