BACKGROUND:Ankle fractures combined with deltoid ligament injury are not uncommon in clinical practice, prone to misdiagnosis and missed diagnosis, resulting in ankle instability, chronic pain and traumatic arthritis. In recent years, because of the research and development of anatomy and biomechanical characteristics of deltoid ligament, the treatment and surgical methods of ankle fracture combined with deltoid ligament injury have progress and development, but it remains controversial. OBJECTIVE:To evaluate the clinical effect of suture anchor repair in the treatment of ankle fracture combined with deltoid ligament injury. METHODS: Twenty-seven patients with ankle fracture combined with deltoid ligament injury were selected between January 2010 and January 2013. The lateral maleolus and posterior maleolus fracture patients were treated with open reduction and internal fixation, and al the deltoid ligament injury patients were treated with anchor repair. The tibiofibular syndesmosis isolated patients received internal fixation with a cancelous bone screw. RESULTS AND CONCLUSION:Al 27 patients were folowed-up for 11-35 months, averagely 23 months. The evaluation according to the American Orthopaedic Foot and Ankle Society score system showed that the excelent and good rate was 74.1%. The results indicate that anchor could perfectly restore the stability of ankle joint.

443) ?mol/L) due to upper urinary calculous obstruction,urgently treated by pneumatic lithotripsy(EMS,Switzerland) under ureteroscopy,from August 2002 to April 2006 in this hospital.After stone fragmentation and removal,an indwelling double-J stent was placed into the ureter at the same time.Results The continuity of the ureter was restored after one session of lithotripsy in all the 9 cases(14 sides).The ureteral calculi were thoroughly removed on one session in 7 cases(12 sides).Few residual stones were found in the renal pelvis in 2 cases(2 sides),in one of which the stones were spontaneously expelled after oral medication,and in another,after extracorporeal shock wave lithotripsy(ESWL).No severe complications happened,such as ureteral avulsion,rupture,or perforation.Concentrations of serum creatine were decreased to normal levels within 3~7 days after operation in all the 9 cases.The gross blood urine disappeared in 1~4 days postoperatively.The patients were discharged from the hospital after 3~7 days (mean,5 days) after operation.The double-J catheter was removed at 1~2 months postoperatively.Follow-up examinations in 7 cases for 2~30 months(mean,14 months) found normal levels of serum creatine and no recurrent urinary stones under B-ultrasonography or X-ray radiography.Conclusions Ureteroscopic pneumatic lithotripsy in the treatment of acute renal failure due to upper urinary calculous obstruction is an effective treatment with short operation time,safety,and minimal trauma.By using this procedure,both sides of ureteral stones can be removed on one session.

Objective To evaluate the curative effectiveness of ureteroscopic pneumatic lithotripsy in the treatment of ureteral lithiasis.Methods Ureteroscopic pneumatic lithotripsy was performed in 158 cases of ureteral calculi(163 sides)by using the Wolf F8/9.8 rigid ureteroscope and the EMS pneumatic ballistic lithotriptor from August 2002 to April 2006.The operation was carried out under intravertebral anesthesia.Under the irrigation with normal saline,the ureteroscope was advanced into the ureter.Then the ureteral stones were fragmented by pneumatic lithotripsy and removed.Afterwards,a further exploration of the ureter above the lesion was conducted and a double-J drainage tube was placed.Results The operation time was 15-90 min(mean,40 min).The total successful fragmentation rate was 96.9%(158/163),involving a success rate of 86.6%(13/15)for upper stones,96.9%(46/49)for middle stones,and 100%(99/99)for lower stones.The stone migration into the renal pelvis was encountered in 2 cases of upper ureteral calculi(treated by extracorporeal shock wave lithotripsy following a double-J tube placement)and in 3 cases after stone fragmentation(treated by stone expulsion with drugs or extracorporeal shock wave lithotripsy following a double-J tube placement).Ureteral perforation happened during the procedure in 3 cases(1.8%),requiring a double-J tube placement.No serious complications occurred,such as ureteral mucous avulsion or rupture and injuries of neighboring organs or vessels.No conversion to open surgery was required.Follow-up checkups for 1-38 months in 125 cases with B-ultrasonography or KUB film found no recurrence.Conclusions Ureteroscopic pneumatic lithotripsy is a safe,effective,and feasible technique for ureteral lithiasis.

This paper mainly discussed a bacterial stain with high flocculating activity isolated from cantaloupe juice .The strain was named Bacillus sp.B_(53) based on colony morphology, physiological and biochemistry experiments. The new flocculant was purified and shown to be a homopolymer of glutamic acid by HLPC analysis and thin layer chromatography, and presumed to be Poly ?-glutamic acid(?-PGA). ?-PGA 12.48g/L was achieved in shake flask. The purified material showed a absorption peak at 212nm, and was only composed of L-Glu. The MW could be detected through SDS-PAGE, and its MW was about a molecular mass between 440kD with 669kD. This bioflocculant efficiently flocculated various organic and inorganic suspensions. It's flocculanting effect on kaolin and ([BF]Ca(OH)_2[BFQ]) was superior to others.

Objective To investigate the relationship between apoptosis of bone marrow cells and tumor necrosis factor-?(TNF-?),Fas/FasL expression in children with aplastic anemia.Methods The concentration of TNF-? in supernatant of cultured bone marrow mononuclear cell(BMMC) was measured by enzyme linked immunosorbent assay.The expression of Fas/FasL,apoptosis ratio of bone marrow CD34+ cell were evaluated by flow cytometry.Results The concentration of TNF-? in supernatant of cultured BMMC in AA group[SAA (27.9?8.20) ng/L;CAA (23.6?6.78) ng/L] increased significantly compared with control group(t=3.432 P0.05).Apoptosis ratio of CD34+ cell in SAA group[(24.6?9.56)%] and CAA group[(20.9?7.32)%] significantly increased compared with control group(t=3.492,3.458 Pa0.05).The concentration of TNF-? was positively correlated with the expression of CD34+ Fas+ in all types AA children(r=0.542 P0.05).Conclusions TNF-? and Fas/FasL system can be involved in inducing CD34+ cell apoptosis.This may contribute to understanding the decreased number of stem cells and bone marrow failure.

Objective To evaluate the expression of WWOX gene in breast cancer and its relation to hypermethylation of WWOX gene CpG island. Methods The expression of WWOX protein was evaluated by immunohistochemical staining in breast cancer cell line and breast cancer tissues.Methylation specific PCR(MSP)was used to check whether it Was methylated in the promoter and exon 1 of WWOX.Results Deletion in the WWOX expression was observed more frequently in invasive breast tumors,(32.2%)than normal breasttissues(5.4%)(P＜0.01).20.3% of premenopause eases were completely negative for WWOX expression compared to 57.2% of postmenopause breast carcinomas(P＜0.01).Furthermore,23.1% of Stage Ⅰ(6/26),28.6%of Stage Ⅱ(10/35),46.2%of Stage Ⅲ(12/26)tunlors showed negative WWOX protein expression.In breast cancer specimens.methylation rate of promoter and exon 1 CpG island of WWOX gene was 55%and 45%respectively.Whereas.WWOX CpG islands of normal mammary tissues were completely unmethylated in all cases.CpG islands of WWOX promoter and exon 1 were methylated in MDA-MB-231 cell line but not MCF-7 cell.Conclusions Some deletion in WWOX expression is common in breast cancer and methylation of WWOX DNA CpG islands plays a crucial role in the silence of WWOX.WWOX may play a role in the carcinogenesis and development of breast cancer.

Objective To assess the efficacy and safety of flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy in the treatment of upper urinary tract calculi.Methods The flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy was performed on 26 patients from Jul 2005 to Jan 2007. Among these patients, 8 had bilateral renal calculi and ureteral calculi, 5 had multiple renal calculi, 4 had renal calyx calculi and 9 had ureteral calculi. The average diameter of the calculus was 2.2 cm (range from 1.0-3.2 cm). Four patients had mild hydronephrosis, others had moderate or severe hydronephrosis. Insufficient renal function was noted in 13 cases. The procedure was performed via a single tract through the middle calyx under the ultrasonic guidance in all cases.Results Twenty-two cases achieved stone free at primary procedure, secondary procedure was needed in 4 cases. A 18 F tract was used in 18 cases and 24 F tract was used in the left 8 cases. The average operation time was 72 min, stone-free rate was 96.2%(25/26),and there was no blood transfusion. One patient had fever after the procedure and recovered 2 days after the administration of antibiotics. No other complication was recorded. In an average 11 month follow-up in 22 patients, hydronephrosis reduction was significant observed by ultrasound scan. No calculus relapse was found.Conclusions Flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy is an effective and minimally invasive technique for the treatment of upper urinary tract calculus. It has the advantages in dealing with the calyx and ureteral calculus located in the proximal or middle segment as well.

Neuropathological, clinical epidemiology and animal models studies provide clear evidence for the activation of neuroinflammation in Alzheimer's disease (AD), and long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is linked with reduced risk to develop the disease. But the clinical trials got a negative outcome with traditional NSAIDs treating AD. The therapeutic effects of NSAIDs on Alzheimer's disease are still not clear based on the present research. Profound study for anti-inflammatory mechanisms and standardized clinical trials are needed. As cause and effect relationships between neuroinflammation and AD are being worked out, the challenge is how to realize the effect of traditional NSAIDs on treating AD.
