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 summary the experience of living donor liver transplantation (LDLT) in order to improve therapeutic effect of LDLT. Methods We retrospectively analyzed the clinical data of donors and recipients of 22 LDLT cases, evaluating patients' and donors' preoperative assessment, surgical strategies and postoperative complications. Results Donor's grafts harvested included 2 left lateral lobes, 6 left half livers, 1 extended left half liver, 5 right half livers and 8 extended right half livers. Postoperatively all donors recovered without severe post-transplantation complications. Among 13 adult and 9 child receipients, there were 8 recipients suffering from posttransplantation complications, including intra-abdominal severe infection in one case, delayed liver function recovery complicating incisional infection in one case, intra-abdominal hemorrage complicating thrombogenesis of the hepatic artery in one case. All these 3 patients died. One child recipient of hepatic failure died of heart and respiratory failure after operation. Other non-lethal complications were bile leakage in 2 cases, refractory ascites in one and deep venous thrombosis of the lower limb in one. These complications were cured without laparotomy. Finally 18 recipients were fully recovered and discharged. Late post-operative complications included strictures of biliary tract in 3 cases which were treated with PTCD and indwelling stent, the obstructive jaundice due to achalasia of sphincter of Oddi was treated with endoscopic sphincterotomy. These 4 patients' are on stable condition and the liver function is normal. Conclusions Select proper donor and optimal surgical strategy are extremely helpful to secure donors and recipients during the procedure of LDLT.

Objective To provide applied anatomic data for relevant operations of blood vessels of perisacral promontory(BVPSP). Methods The composition of BVPSP including origin, course, diameter of the middle sacral vessels, the distance between the sacral promontory and the sacral 1 transverse trunk were observed on 37 adult cadavers. Result The BVPSP is composed of the common and internal iliac vessels, the superior segment of the middle sacral vessels and the sacral 1 transverse trunk. Middle sacral artery comes from abdominal aorta. Middle sacral veins are thin walled without valves. The average diameter of middle sacral artery and vein is 1.02 mm and 2.53 mm respectively. The distance between the sacral 1 transverse trunk and the sacral promontory is 5.75 mm. Conclusion The composition of BVPSP, especially middle sacral veins, plentiful vascular anastomosis are the anatomical basis leading to massive hemorrhage in the relevant operations.

Objective To study the expression of long non-coding RNA (lncRNA)-urothelial carcinoma associated 1 (UCA1) and miR-34b in bladder cancer and its correlation to the clinicopathologic features of bladder cancer.Methods Between January 2011 and October 2012,the expression of UCA1 and miR-34b in 5 bladder cancer cell lines (T24,BIU-87,EJ,T24-MMC,T24-ADM) and 1 normal bladder cell lines (SV-HUC-1) were measured by real-time reverse transcription-polymerase chain reaction (RTPCR).Meanwhile,the 56 bladder cancer specimens and paraneoplastic normal bladder tissues,which diagnosed by pathology were collected from bladder cancer patients undergoing radical resection of bladder.Among them,41 cases were male and 15 cases were female.The mean age was (68.4 ± 7.5)years old,range 52 to 78 years.43 cases were older than 65 years old,and 13 cases were less than 65 years old.The pathological classification included non muscle-invasive bladder cancer (NMIBC) 18 cases,muscle-invasive bladder cancer 38 cases;low grade papillary urothelial carcinoma 22 cases,high grade papillary urothelial carcinoma 34 cases;12 cases were primary lesion,the other 44 cases were diagnosed as tumor recurrence.Real-time RT-PCR was performed to analyze the expression of UCA1 and miR-34b.Results The relative expression levels of UCA1 in the normal bladder cell lines (SV-HUC-1) and 5 bladder cancer cell lines (T24,BIU-87,EJ,T24-MMC and T24-ADM) were (0.0675 ± 0.0133),(0.2934 ± 0.0531),(0.4246 ± 0.0650),(0.4206 ± 0.0826),(0.6472 ± 0.0875) and (0.7165 ± 0.1032),respectively (P ＜ 0.05).Moreover,the expression levels of UCA1 were up-regulated in 2 drug resistant bladder cancer cells lines T24-MMC (0.6472 ± 0.0875)and T24-ADM (0.7165 ± 0.1032),as compared with the T24 bladder cancer lines (0.2934 ± 0.0531),respectively (P ＜ 0.05).However,the expression levels of miR-34b in 5 bladder cancer cell lines [T24 (0.1600 ± 0.0455),BIU-87 (0.1720 ± 0.0658),EJ (0.1150 ± 0.0352),T24-MMC(0.0576 ± 0.0087),T24-ADM (0.0510 ± 0.0125)] were decreased (P ＜ 0.05),as compared with normal bladder cell lines SV-HUC-1 (0.6384 ± 0.1083).Moreover,the expression levels of miR-34b were down-regulated in 2 drug resistant bladder cancer cells lines T24-MMC (0.0576 ± 0.0087) and T24-ADM(0.0510 ± 0.0125),as compared with the T24 bladder cancer lines T24 (0.1600 ± 0.0455),respectively (P ＜ 0.05).The relative expression levels of UCA1 and miR-34b in bladder cancer tissues and paraneoplastic normal bladder tissues were (0.4225 ± 0.0714) vs.(0.0532 ± 0.0192) and (0.0340 ± 0.0134)vs.(0.5643 ±0.0616),respectively (P ＜0.05).Statistical correlation analysis showed that UCA1 to be significantly negative correlated with miR-34b in bladder cancer specimens(r =-0.54,P ＜ 0.05).The high level of UCA1 and low level of miR-34b were significantly correlated with tumor malignant grade,invasiveness and recurrence.The 3-year overall survival rate (OS) in UCA1 (+)/miR-34b(-) group (27.6％) were significantly worse compared with non UCA1 (+)/miR-34b (-) group (73.7％).Conclusion High expression of UCA1 and low expression of miR-34b were associated with the occurrence and development of bladder cancer.
