ObjectiveTo evaluate effect of periarticular osteotomy in the treatment of asymmetrical ankle arthritis.MethodsSixty-five patients with asymmetrical ankle arthritis were treated with periarticular osteotomy between February 2005 and May 2011,including 43 females and 22 males,aged from 35 to 74 years (mean,55.5 years).According to the Takakura classification of ankle arthritis,there were 29 patients in grade 2,32 in grade 3 and 4 in grade 4.Supramalleolar tibial osteotomy were performed in 20 patients,supramalleolar tibial and fibular osteotomy in 12,supramalleolar osteotomy combined with calcaneal osteotomy in 30 patients,and supramalleolar tibial and fibular osteotomy combined with calcaneal osteotomy in 3patients.Forty three patients underwent ligament reconstruction procedures.Based on radiographs,the tibial anterior surface angle (TAS) and tibial lateral surface angle (TLS) were compared before and after operation.AOFAS-AH score was used to evaluate the function of the ankle.ResultsFifty-nine patients were followed up for an average of 35.7 months (range,7 to 94 months).Bone healing was observed in all patients,and the average healing time was 7 to 8 weeks.The average AOFAS-AH score was improved from 49.7 points preoperatively to 78.6 points 12 months postoperatively.Tbe average TAS and TLS was improved from 86.1° and 70.0° preoperatively to 93.9° and 81.5° 6 months postoperatively,respectively.Delayed wound healing occurred in 5 patients,which was resovled after nursing care.Forty-two patients felt excellent about results,15 felt good and 2 fell fair.ConclusionPerarticular osteotomy is a sound method in the treatment of asymmetrical ankle arthritis,based on chosing proper patients.The procedure can decrease the contact pressures on the degenerated cartilage and prolong the life span of the ankle.

Objective To investigate the clinical features and management of hepatolithiasis associated with intrahepatic cholangiocarcinoma. Methods Data of 84 patients of hepatolithiasis associated with intrahepatic cholangiocarcinoma in our hospital from 1990 to 2009 were retrospectively analyzed.Results The incidence of intrahepatic cholangiocarcinoma in patients of hepatolithiasis was 4. 6%(84/1840), among them only 47 patients got a definite diagnosis before operation. All cancer located in the bile duct containing cholelith. In 20 patients intrahepatic cholangiocarcinoma was identified 6 - 16 years after lithotomy. The clinical manifestation of hepatolithiasis associated intrahepatic cholangiocarcinoma included:refractory hepatic abscess, incurable infection of intrahepatic biliary tract, and progressive obstructive jaundice. Only 35 patients received radical excision, 26 patients received palliative excision, 4 patients received radiofrequency ablation therapy, 19 patients received biopsy only. Conclusions There has been a considerable high coincidence between intrahepatic cholangiocarcinoma and hepatolithiasis. Resection of the lobe containing intrahepatic stones may help to prevent the development of intrahepatic cholangiocarcinoma.

Objective To evaluate the influence of simple subtalar arthrodesis to the motion and degeneration of midfoot.Methods Data of 37 patients (27 males,10 females) with an average age of 42.6 years who had undergone subtalar joint fusion from January 1996 to August 2011 were retrospectively analyzed.The MOS item short form health survey (SF-36),American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score were used.Midfoot sagittal and coronal motion were measured on ankle radiographs of maximum plantar flexion and dorsiflexion.On sagittal plane,the Meary angle was measured and the bilateral tarsometatarsal joints mobility was compared.On coronal plane,tibio-plantar angles (TPA) on 30 degrees varus slope and 30 degrees valgus slope were respectively measured on the anterio-posterior ankle X-ray films to observe the changes of midfoot activities.Besides,single photon emission computed tomography/computed tomography (SPECT/CT) of bilateral foot and ankle was taken to estimate the degeneration of midfoot joint.Results All the 37 patients were followed-up,with mean follow-up period of 9.2 years.The average SF-36 scores was increased from 34.26± 11.02 points preoperatively to 77.59± 12.57 points postoperatively.The average AOFAS midfoot scores were 86.14± 16.79 points preoperatively and 86.43± 16.70 points postoperatively without any statistical significant difference.On sagittal plane,medial tarsometatarsal joints mobility was limited by 20％.According to coronal plane of varus slope,the average TPA of healthy side and operated side were 61.32° and 64.91°,respectively,so the varus mobility of operated side was limited by 12.5％.While standing on the valgus slope,the average TPA of both sides were 76.54° and 82.28°,which indicated that valgus mobility of operated side was reduced by 42.6％.35.1％ patients of talonavicular joint,56.8％ patients of calcaneocuboid joint,and 27.0％ patients of metatarsal cuboid joint were found mild joint degeneration on SPECT/CT images without any clinical symptoms.Conclusion Subtalar arthrodesis can affect midfoot with less limit of sagittal mobility and more limit of coronal movement.And the lateral joints degeneration is more likely to happen for their compensatory activity.

Objective To evaluate the curative effect and related factors of the treatment for the osteochondral lesion of talus (OLT) by the osteochondral autografts harvested from medial femoral condyle of the ipsilateral knee.Methods The data of 15 OLT patients was retrospectively analyzed who received the operation during July 2009 to November 2012.There were 8 males,and 7 females,with an average age of 49.6±17.2 years (range,19-73 years).International Knee Documentation Committee (IKDC) and Lysholm score were used to evaluate the knee function preoperatively and postoperatively respectively.The ankle functions and pain were assessed according to American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hind-foot score and visual analogue scale (VAS) preoperatively and postoperatively respectively.Correlations between age or follow-up duration and all the score increments were further analyzed by Spearman rank correlation test.Results Twelve patients complete the follow up,with an average duration of 21.8±10.4 months.The average IKDC,Lysholm,AOFAS,and VAS were 90.91±6.44,95.33±8.00,63.58±18.50,and 7.25±1.54 respectively before operation,and 85.63±11.89,90.75±11.83,90.33±4.98,2.17±1.19 respectively after operation.Correlation coefficients of age between AOFAS,Lysholm,and IKDC score increments were -0.74,-0.63,and-0.76,respectively.There were 4 cases which received excellent effect (33％),5 cases (42％) good and 3 (25％) fair.Conclusion The ankle joint function of patients with OLT recovered well by treated with osteochondral autografts harvested from medial femoral condyle of the ipsilateral knee operation.A correlation was found between patients' age and postoperative functional recovery of ankle and knee joint.

Objective To study the effects of decoy strategy targeted to NF-KB on the development of trauma-associated liver inflammation in rats. Methods In this study, 108 Wistar rats were randomized into 3 groups: control group, traumatic inflammation group and traumatic inflammation plus decoy ODN group. Rats were sacrificed on 3,6,12,24,48 and 72hrs in each group respectively. Liver functions and structural changes were examined and compared between the groups. DNA binding activity of NF-KB in liver tissue was measured by EMSA. TNF-α and IL-6 gene expressin in liver tissue was assessed by RT-PCR and TNF-α and IL-6 protein level was determined by ELISA. Results The DNA binding activity of NF-kB in liver rose at 3 hours after induction of liver inflammation following trauma and peaked at 12 hours. Correspondingly, both the mRNA and protein levels of TNF-α and IL-6 elevated significantly, as well as the serum alanine aminotransferase level culminating at 24 hours after surgery. Hepatocytes was edematous, degeneration and necrosis, with dramatic destruction of lobular structures. All these changes were significantly inhibited with NF-KB decoy oligodeoxynucleotides. Conclusions Decoy oligodeoxynucleotides specifically inhibit the activity of NF-kB, and the release of pro-inflammatory cytokines, TNF-α and IL-6 release from the liver in response to traumatic inflammation decrease, hence the injury on liver structures and functions were alleviated.

OBJECTIVETo investigate the clinical application of laparoscopy-assisted subtotal colectomy with transanal specimen extraction for slow transit constipation(STC).

METHODSRetrospective analysis was performed on the clinical data of 8 cases with STC undergoing the procedure mentioned above from February to November 2013. Pre-and post-operative constipation was assessed using Wexner Constipation and Incontinence Scales, and quality of life was assessed using Gastrointestinal Quality of Life Index.

RESULTSAll the operations were completely successful without postoperative complications, such as intestinal fistula, pelvic infection, anastomotic stricture, intestinal obstruction. The Operative time was (287.6 ± 21.5) min, blood loss was (109.7 ± 41.1) ml, time to first flatus was (2.5 ± 0.9) d. The proportion of postoperative constipation symptom index improvement was(77.6 ± 8.3)%. Postoperative quality of life score was 97.3 ± 15.7, significantly higher than that before operation(P<0.05). Postoperative Wexner constipation score was 8.8 ± 3.7, significantly lower than that before operation.

CONCLUSIONLaparoscopy-assisted subtotal colectomy with transanal specimen extraction in the treatment of STC has good short-term efficacy with obvious improvement in quality of life.

Objective:To explore the long-term clinical efficacy of subtalar arthrodesis for treating sinus tarsi syndrome (STS) with peroneal spasm.Methods:Clinical informationof 32 patients with sinus tarsi syndrome complicated with peroneal spasm who were treated by subtalar arthrodesis from January 2006 to December 2016 was retrospectively analysed. There were 19 males and 13 females, aged 29.3±10.9 y (range: 13-56 y), and course of disease is 2.1±1.7 y (range: 1-10 y). All patients suffered from tarsal sinus pain and intractable peroneal spasm. The aetiology was foot or ankle inversion sprainin 25 patients, lower limb nerve injury in four patients, and ambiguous causes in three patients.The patients were divided into three groups according to their initial symptoms. Group A: Patients with simple peroneal spasm underwent tarsal sinus debridement firstly and subtalar joint fusion after symptom recurrence. Group B: Patients with peroneal spasm combined with other symptomsunderwent sinus tarsal cleansing and other symptomatic operations, and received subtalar joint fusion after symptoms recurred. Group C: Patients with peroneal spastic flat foot were treated withsubtalar joint fusion directly.Preoperative and postoperative American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores, visual analogue scale (VAS) scores for pain during daily activities, and 36-item short form health survey (SF-36) scoreswere investigated.Results:32 cases were successfully completed operation, following-up 87 (40, 133) months. Group A(14 cases): The patients were treated withsinus tarsi debridement first. But their symptoms recurred in an average of 7.7 months after surgery. Later they received subtalar joint fusion. Group B (15 cases): In addition to tarsal sinus debridement, 3 cases were undergone tarsal coalitions resection, 3 cases were got denervation of tarsal sinus, 6 cases were received subtalar joint stabilization, and 3 cases were released their peroneal tendons. Their symptoms recurred in an average of 6.4 months after surgery, and they eventually were undergone subtalar arthrodesis. Group C (3 cases): Their initial symptoms were severe, manifested as rigid flat feet caused by peroneal tendons spasm, so they directly underwent subtalar joint fusion. The average AOFAS ankle and hindfoot scores for all patients increased from 27.86±10.79 points before treatment to 86.34±7.17 points at the last follow-up after operation ( t=23.505, P<0.05). The VAS scores decreased from 8.00±1.57 points before treatment to 1.91±1.06 points at the last follow-up after operation ( t=18.407, P<0.05). The SF-36 scores increased from 35.84±12.12 points before treatment to 86.20±10.32 points at the last follow-up after operation ( t=24.203, P<0.05). Conclusion:Sinus tarsi syndrome with peroneal spasm due to its complicated etiology and pathogenesis can give priority to sinus tarsal debridement or other symptomatic surgeries. If the symptoms recur, subtalar arthrodesis can be an alternative choice to achieve the long-term effects.
