OBJECTIVETo study the clinical effects of Achillon for the treatment of acute Achilles tendon rupture (AATR).

METHODSFrom April 2009 to April 2010, 19 patients with AATR who were treated with Achillon were retrospectively analyzed. There were 17 males and 2 females, with an average age of 40.2 years (30 to 58 years). There were 9 cases of sports injury, and 2 case of fall injury. The time from injury to surgery ranged from 0 to 8 days (2.2 days on average). The results of Thompson test and single heel rise test were positive in 19 cases. Clinical data were assessed with the patient satisfaction and the AOFAS hindfoot score during follow-up.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 28 months (19.9 months on average). The average operation time was 41 minutes. There were no wound infections, recurrent rupture, or sural nerve complications. At the latest follow-up, 18 patients were totally satisfied with the surgical result, 1 patient feel generally due to mild pain when running. None of the patients were dissatisfied with the final results the latest follow-up. At the latest follow-up, the AOFAS score was 98.42 +/- 3.29 (89 to 100). All the patients regained normal range of motion and were able to resume their previous activities at six months after operation, with a high rate of satisfaction. Average decreased of mid-calf circumference was (0.82 +/- 0.85) cm (ranged from 0 to 3 cm).

CONCLUSIONTreatment with Achillon is safe, effective for AATR with low incidence of complications and early active rehabilitation can be carried out. It is a good method to treat AATR.

OBJECTIVETo identify possible reasons of rotational mismatch between tibial component and femoral component in total knee arthroplasty and choose a right reference axis for placing the components in the operation and to decrease the complications.

METHODSForty normal Chinese knees were studied. There were 20 men and 20 women, and average age was 34 years (range, 18 - 42 years). The images of cross sections of the distal femur were obtained by spiral CT scanning (0.5 mm thickness). Scan direction was aligned to be in the plane perpendicular to the mechanical axis of the tibia. On the images of the distal femur and the proximal tibia, three baselines for the anteroposterior axis of the femoral component were drawn based on the clinical epicondylar axis and the surgical epicondylar axis and 3 degrees lateral rotated to the posterior condylar surfaces of the femur separately, and a baseline for the anteroposterior axis of the tibial component was drawn based on the medial 1/3 of the tibial tuberosity. The rotational mismatch angles were measured between each component by using the Autocad software.

RESULTSThe mean rotational mismatch angle between tibial component and femoral component is 2.94 degrees for the clinical epicondylar axis, 6.50 degrees for the surgical epicondylar axis and 6.83 degrees for 3 degrees lateral rotation of the femoral component referenced to the posterior condylar axis separately.

CONCLUSIONSLandmarks of each bone were the intrinsic cause of the rotational mismatch in total knee arthroplasty. The clinical epicondylar axis can be chosen for the ideal reference to rotational alignment of the femoral component because of its minimal rotational mismatch between each component.

Objective:To investigate the differences in matrix metalloproteinases (MMPs) and matrix metalloproteinase inhibitors (TIMPs) from diseased splenic vein (DSVs) and varicose great saphenous vein (VGSVs) under high hemodynamics.Methods:Seventy-two specimens of DSVs,normal splenic veins (SVs),VGSVs,and normal great saphenous vein (GSVs) were collected.Venous wall in the four groups,MMP-2,MMP-9,TIMP-1,and TIMP-2 protein expression were observed and MMP-2,MMP-9,TIMP-1,TIMP-2 proteins positive expression ratio and mRNA expression were determined.Results:DSVs and VGSVs in the two groups,MMP-2,MMP-9,TIMP-1,TIMP-2 proteins with clustered strong expression were observed;In DSVs group,MMP-2,MMP-9,TIMP-1,TIMP-2 protein positive expression ratio and mRNA expression were significantly increased compared with SVs group,while in VGSVs group,MMP-2,MMP-9,TIMP-1,TIMP-2 protein positive expression ratio and mRNA expression were significantly increased compared with GSVs group (P＜0.05).VGSVs/GSVs ratio was significantly increased compared with DSVs/SVs ratio (P＜0.05).Conclusion:Under high hemodynamics,the dysequilibrium of MMPs and TIMPs from splenic vein and great saphenous vein,These results may be one of the molecular mechanism in vascular remodeling.

OBJECTIVETo determine the value of using a closed-suction drain in cemented knee arthroplasty.

METHODSOne hundred patients were prospectively randomized into two groups, one group underwent cemented total knee replacement with a single deep closed-suction drain, and the other group (n = 50) no drain.

RESULTSThe total blood loss was significantly greater in those with a drain although those without lost more blood into the dressings. There was no statistical difference in the postoperative swelling or pain score, ecchymosis, deep vein thromboses (DVT), time at which flexion was regained or the incidence of infection at a minimum of two years after surgery in the two groups.

CONCLUSIONThere is no evidence to support the use of a closed-suction drain in cemented knee arthroplasty.

OBJECTIVETo study the efficacy of Huai Qi Huang granules in the treatment of childhood primary nephrotic syndrome.

METHODSBetween July 2009 and December 2011, patients who were admitted and diagnosed for the first time as childhood primary nephrotic syndrome were randomized into a treatment group (Huai Qi Huang granules plus glucocorticoid; n=23) and a control group (glucocorticoid alone; n=19) for a prospective study. The two groups were compared for regression time of edema, time to urinary protein clearance, relapse rate, incidence of infection, dosage of glucocorticoid, and humoral and cellular immunological indicators.

RESULTSThere were no significant differences in regression time of edema, time to urinary protein clearance, and relapse rate between the treatment and control groups (P>0.05). The treatment group had significantly lower incidence of infection and daily dose of glucocorticoid (at month 6) than the control group (P<0.05). Humoral and cellular immunological indicators showed no significant differences between the two groups (P>0.05). No Huai Qi Huang-related adverse events were observed in this study.

CONCLUSIONSHuai Qi Huang granules treatment can reduce the dose of glucocorticoid and the incidence of infection in children with primary nephrotic syndrome and has a favourable safety.

OBJECTIVETo explore clinical characteristics and outcome of deep vein thrombosis(DVT) in children with acute lymphoblastic leukemia (ALL).

METHODSA tatol of 266 patients were diagnosed as ALL from January 1, 2010 to May 31, 2016. The clinical data of 12 cases of patients with DVT were retrospectively analyzed, 183 cases diagnosed before January 1, 2015 were received chemotherapy with the scheme of SCMC-05. The other cases were treated by the scheme of CCCG. All the patients received central venous catheter.

RESULTSThe DVT happened in 12 cases including 10 cases of limb DVT and 2 cases of intacranial venous sinus thrombosis. The DVT mostly occured in intermediate risk ALL patients, the infection and coagulopathy existed in most patients. They were treated with low molecular heparin(LWHP), among them 5 cases were given extubation; the thrombus disappeared in 6 cases after 1 week; the intracranial venous sinus thrombosis in 1 case did not obviously improved after 6 months of treatment. The ALL children with DVT were treated with LWHP when using L-ASP, as a result no thrombuses happened.

CONCLUSIONCentralvenous catheter and chemotherapeutic drugs were the major cause of DVT. Abnormal coagulation, infection, and risk stratification are another risk factors for thrombosis. ALL children thrombosis are benefited from LWHP prevention when using L-ASP again.

OBJECTIVE: To explore the influencing factors in children with chronicity immune thrombocytopenia (ITP), and to provide basis for judging the prognosis and treatment in children with ITP. METHODS: The clinical data of children with ITP admitted to The Second Affiliated Hospital of Anhui Medical University in the past 5 years were retrospectively analyzed and followed up for more than 1 year. According to the inclusion criteria, the eligible cases (328 cases in total) were selected and collected through medical record system retrieval, outpatient clinic and telephone follow-up. Independent influencing factors affecting the prognosis of children with ITP were obtained through single-factor and multi-factor logistic analysis, and their predictive value for the prognosis of ITP in children were evaluated. RESULTS: Of 328 children with ITP, 208 were newly diagnosed with ITP (64%), 54 were persistent ITP (16%), 66 were chronic ITP (20%), and the remission rate within 1 year was 79.9%. The results of univariate analysis showed that, age, pre-morbidity history of infection and vaccination, antinuclear antibodies, initial absolute lymphocyte count（ALC） and treatment options were related to the prognosis of the children (P<0.05). Multivariate analysis showed that the history of infection and vaccination before onset, initial treatment options, and ALC at the time of initial diagnosis were independent factors affecting the prognosis of children with ITP (P<0.05). The time for platelet recovery to 100×10 CONCLUSION The initial treatment plan combined with IVIG can reduce the occurrence of chronicity in children with ITP, and its efficacy is better than that of the single corticosteroids group (the platelet recovery time is shorter); history of preceding infection or vaccination, ALC at the time of initial diagnosis are independent factors affecting the prognosis of children with ITP, and the combination of the two shows a better predictive value for the prognosis.
