Treatment of calcaneal fractures has always been the focus of many clinical researchers.The goals of traditional surgical treatment are not only to restore the integrity of calcaneal articular surface but also to reconstruct the anatomy of the calcaneus.More importantly,we need to reduce postoperative soft tissue swelling and incidence of postoperative complications.In recent years,scholars have reported satisfactory clinical efficacy and prognosis resulting from a sinus tarsal approach for treatment of calcaneal fractures.This paper reviews the latest research progress concerning the sinus tarsal approach for treatment of calcaneal fractures at home and abroad,intending to provide helpful information for the clinical surgeons.

BACKGROUND:Early-onset scoliosis is a kind of disease that seriously affects the growth of children’s spine and development of cardiorespiratory function. The treatment of the disease has always been the focus of many clinical researchers.OBJECTIVE:To analyze the therapy for early-onset scoliosis and explore the spinal fusion, spinal non-fusion, conventional growth rod technology and magnetic control ed growth rod technology of early-onset scoliosis. METHODS:We retrieved PubMed, CENTRAL, EMbase, the ISI Web of Knowledge Databases, VIP, CNKI, CBM and Wanfang Database for related studies published from inception of the database to March 2016. The key words were“scoliosis, growing rod, complications”. The included 54 studies were analyzed and discussed. RESULTS AND CONCLUSION:For these children of early-onset scoliosis, we should not only maintain the correction of spine deformities, but also protect the ability of spine growth, keeping the normal cardiopulmonary function. In addition to conventional (non-surgical) treatment, there are surgical treatment (such as spinal fusion and growing rod technique) and magnetical y control ed growing rod, a new technology for the treatment of early-onset scoliosis. A comprehensive understanding of the effect of surgical treatment on the spine growth and cardiopulmonary function of children with early-onset scoliosis wil help to prevent the occurrence of related complications, so as to obtain a better therapeutic effect.

This study was aimed to predict active compounds,drug targets and potential diseases of Yi-Guan decoction (YGD) by network pharmacological technology,and to clarify molecular mechanisms of YGD efficiency on different diseases with liver and kidney yin deficiency syndrome (LKYDS).Chemistry compounds,targets and related diseases from YGD were collected from TCMSP,TCM Database@Taiwan,TCMID,HIT,Drugbank,PubChem and TTD databases.The YGD compounds-targets-diseases network was constructed.The network topology was analyzed by Cytoscape software.The analysis of GO biological processes and KEGG pathways enrichment were performed by DAVID website.The results showed that 849 chemical compounds were identified from Beishashen,Maidong,Danggui,Shengdihuang,Chuanlianzi and Gouqizi.There were 49 active CHM compounds that were both oral bioavailability (OB) ≥ 30％ and drug-likeness (DL) ≥ 0.18,corresponding to 200 target proteins and 264 diseases.The top three GO biological processes were response to organic substance,regulation of cell proliferation,and response to endogenous stimulus,respectively.The top three KEGG pathways were pathways in cancer,hepatitis B,and prostate cancer,respectively.It was concluded that the analysis on YGD was conducted based on network pharmacology,and the compound-target-disease network was built,which may help to clarify the mechanisms of YGD efficiency on different diseases with LKYDS.It can provide clues to find new potential clinical adaptation of disease and new drugs.

Background: Early diagnosis and staging of liver fibrosis are important for the prognosis and evaluating the survival of patients.Aims: To systematically assess the diagnostic value of transient elastography (TE) for staging of liver fibrosis in patients with chronic liver disease.Methods: PubMed,Embase,Cochrane Library,CNKI,Wanfang and VIP from Jan.2001 to Dec.2015 were retrieved to collect the articles with staging of liver fibrosis in patients with chronic liver disease by TE.Data extraction was conducted.Article quality was evaluated by quality assessment of diagnostic accuracy studies 2 (QUADAS2).Meta-analysis was conducted by Stata 12.0 software.Results: Twenty articles involving 5 748 patients were included.Meta-analysis showed that the combined sensitivity,specificity and AUC of TE for diagnosing significant fibrosis (≥F2) were 0.78 (95％ CI: 0.73-0.82),0.85 (95％ CI: 0.80-0.88) and 0.88 (95％ CI: 0.85-0.91),respectively.The combined sensitivity,specificity and AUC for advanced fibrosis (≥F3) were 0.89 (95％ CI: 0.86-0.91),0.88 (95％ CI: 0.85-0.91) and 0.94 (95％ CI: 0.92-0.96),respectively.The combined sensitivity,specificity and AUC for cirrhosis (F4) were 0.91 (95％ CI: 0.86-0.95),0.89 (95％ CI: 0.87-0.92) and 0.95 (95％ CI: 0.93-0.97),respectively.Conclusions: TE technique has a good diagnostic value in assessing significant fibrosis,advanced fibrosis and cirrhosis in patients with chronic liver disease,especially for advanced fibrosis and cirrhosis.

Objective To investigate the clinical application of pedicle screw placement technique for pelvic external fixation.Methods A retrospective review was made on 63 patients (37 males and 26 females;23-67 years of age) managed with anterior or combined anterior and posterior external fixation of pelvic fracture between February 2011 and May 2014.According the ways of screw insertion,the study was divided into two groups:observation group (screw was inserted using the pedicle screw placement technique,n =36) and control group (screw was inserted directly,n =27).Tile fracture classification was 11 patients with type B1,7 type B2,7 type B3,5 type C1,3 type C2 and 3 type C3 in observation group,and 9 patients with type B1,7 type B2,4 type B3,4 type C1,2 type C2 and 1 type C3 in control group.Operation time,rate of the penetration,X-ray fluoroscopy times,screw loosening rate,and postoperative complication rate were documented.Radiologic evaluation of the pelvis was detected with the Matta' s criteria.At the final follow-up,functional evaluation of the pelvis was evaluated with the score proposed by Cole et al.Results Period of follow-up was (14.7 ± 3.2)months in observation group and was (13.8 ± 3.1) months in control group.A total of 190 screws were placed in observation group and 138 screws in control group.Better results were found in observation group than in control group with respect to operation time [(18.8 ± 4.1) min vs.(22.6 ± 5.4) min],rate of the penetration (1.6％ vs.8.7％),X-ray fluoroscopy times (1.6 ± 0.8 vs.2.2 ± 0.9),and screw loosening rate (1.6％ vs.6.5％).There were no significant difference between observation and control groups in percentage of good to excellent reduction(89％ vs.85％) and function score [(35.6 ±3.0) points vs.(34.8 ± 3.9) points] (P ＞ 0.05).After operation,3 patients with lateral femoral cutaneous nerve paralysis and none with wouud infection were found in observation group;3 patients with lateral femoral cutaneous nerve paralysis and one patient with wound infection were found in control group.Conclusion Either the pedicle screw placement technique or conventional technique achieves satisfactory clinical effect,but the former owns better results in operation time,screw insertion accuracy,fluoroscopy frequency and rate of screw loosening,suggesting a fast,safe,and effective screw placement method in pelvic external fixation that should be widely applied.

AIM:To observe and analyze the effect of cardiopulmonary bypass ( CPB) for 30 min on surface ultra-structure and mechanical properties of the erythrocyte membrane by atomic force microscopy (AFM).METHODS:Ten cases of elective patients in cardiac surgery were selected in the study and divided into control ( CON) group and CPB group.The central venous blood (2 mL) before surgery and 30 min after CPB was collected with heparin anticoagulation . The non-circular red blood cells were counted under a stand fluorescence microscope .AFM was used to examine the ultra-structure of the membrane surface and measure the force curve of the erythrocytes .RESULTS:The percentage of non-cir-cular red blood cells in CPB group showed no statistically significant differences as compared with CON group .AFM images showed that the significant differences of membrane surface concave and convex , evenness , particle distribution , the sur-face average roughness (Ra), the surface root mean square roughness (Rq) and cell membrane adhesion between CPB group and CON group were observed .However, the membrane deformation resilience and curve slope had no significant difference between the 2 groups.CONCLUSION:Cardiopulmonary bypass for 30 min changes the morphology and ultra-structure of the erythrocyte membrane surface , and increases the adhesion between cells .

Objective: To investigate the effect of gross total resection on the local control and survival of patients with stage IV neuroblastoma (NB) and analyze the extent of surgical resection of primary tumors that affects patient survival. Methods: A total of 96 patients with stage Ⅳ NB who were admitted to the Sun Yat-Sen University Cancer Center between January 2000 and December 2011 were analyzed. The patients were treated with combined-modality therapy, including chemotherapy, surgery, and/or radiotherapy. The patients were divided according to the extent of surgical resection of primary tumor into the following groups: group A, biopsy or tumor removal of less than 50% of the primary lesion; group B, incomplete resection of more than 50% but less than 90% of the lesion; group C, removal of more than 90% of the lesion; and group D, complete resection with or without macroscopic residual tumors. The survival rates of each group were analyzed. Results: The median age of the 96 patients was 4.4 years, ranging from 1.2-18.8 years. The overall 3-year progression-free survival (PFS) and overall survival (OS) of the total patients were 32.8% and 36.7%, respectively. A total of 24 cases were assigned in group A, 10 in group B, 23 in group C, and 39 in group D. Subgroup analysis revealed that the 3-year PFS rate was 17.5% for group A, 20.0% for group B, 45.1% for group C, and 40.5% for group D. The PFS rates were not statistically significant-ly different between groups A and B (P=0.352) and between groups C and D (P = 0.792). However, the OS was higher in groups C and D than that in groups A and B. The 3-year PFS rates were 42.2% and 17.8% for groups C and D (P<0.001), respectively. Conclu-sion: Resection extension of more than 90% of the primary tumor combined with chemotherapy and (or) radiation therapy can improve the survival of patients with stage Ⅳ NB. However, this treatment modality does not affect the treatment outcomes for minimal gross tu-mor residuals.

OBJECTIVETo evaluate the long-term survival of children and adolescents with lymphoblastic lymphoma (LBL) treated by a modified NHL-BFM-90 protocol.

METHODSFrom March 1998 to November 2010, 107 untreated patients with LBL (age <18 years) were enrolled and stratified into three groups (R1, R2 and R3), according to the stage of disease and response to induction chemotherapy. All patients received different intensive chemotherapy regimens based on a modified NHL-BFM-90 protocol. Total treatment duration was 2 years.

RESULTSOf the 107 patients, 79 were boys and 28 were girls, with a median age of 10 years (range 2.5-18 years). Six patients (5.6%) were stage I/II, 101 (94.4%) stage III/IV. The R1, R2 and R3 groups accounted for 5.6%, 71.0% and 23.4%, respectively. 75.7% of the patients had T-LBL, and 24.3% was B-LBL. At a median follow-up duration of 60 months (range 1-186 months), 24 patients died. The 5-year event-free survival (EFS) and overall survival (OS) were 75.5% and 77.8 % for all patients, 100.0% and 100.0% for group R1, 84.5% and 87.5 % for R2, 44.0% and 44.0% for R3, 72% and 73.5% for T-LBL, 86.4% and 88.5% for B-LBL, respectively. Myleosuppression was the major toxicity and need aggressive management.

CONCLUSIONThe modified NHL-BFM-90 protocol is an effective therapy for children and adolescents with LBL in low and intermediate risk. T-LBL had the similar outcomes as B-LBL did. The patients in high-risk group had a poor survival and new protocols are needed.

OBJECTIVETo investigate the relationship between the 3 polymorphic loci of endothelin receptor type A (EDNRA) gene and intracranial aneurysms.

METHODSThree EDNRA gene polymorphisms (rs5335, rs6842241, and rs6841581) were genotyped using polymerase chain reaction-restriction fragment length polymorphism analysis. The genotype and allele frequencies were calculated in the patients and the control group to analyze the association between the gene and the size of aneurysms.

RESULTSNo significant difference was found in the distribution of the EDNRA gene genotypes or allele frequencies between the patients and the control subjects. Only GG genotype of rs6841581 was found to significantly correlate with the size of aneurysms.

CONCLUSIONEDNRA gene rs6841581 has significant associations with the size of intracranial aneurysms, indicating a possible role of EDNRA in the genetic mechanisms of intracranial aneurysms and subarachnoid hemorrhage.
