Objective To discuss the feasibility and long-term effect of free latissimus dorsi muscle flap in repair of severe lower extremity injury in children. Methods From July 1999 to June 2004, nine child patients (at age of 6-13 years) with severe lower extremity injury involving soft tissue defects a-round the calf and the foot associated with complex open fractures, bare dislocation, and injury of the nerve, tendon and artery were repaired with free latissimus donsi flap, with flap area ranging from 30 cm ×12 cm to 10 cm × 5 cm. Results All the latissimus dorsi flaps survived, with success rate of 100%. A follow-up for 4-9 years showed that the flap had sound shape and function and normal blood supply, without significant influence on donor area. Conclusion Latissimus dorsi flap has advantages of constant anatomical site, abundant blood supply, massive area, strong anti-infection ability and less in-fluence on donor area and hence is an ideal method for repairing severe lower extremity injury in children.

The influence of Rosa davurica pall juice on pulmonary adenoma induced by urethan was observed in the experiment, which lasted for 20 weeks. 250 mice were divided into 4 groups at random. Group A was set as control receiving basal diet and tap water only. Another 3 groups were given basal diet, however, group B was given Rosa davurica pall juice 0.2ml/20g boody weight once a week, group C 0.1% urethan solution for drinking freely and group D 0.1% urethan solution plus the juice. The mouss body weight was weighed once a week; the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), the level of lipoperoxides (LPO), lymphocyte transformation and hemolysin were determined once a month, the pulmonary pathological examination was made also once a month. The obtained data were carried out with a 2?2 factorial analysis. The result were as follows:(1)the incidence of pulmonary adenoma of group C(100%) was significantly higher than that of group D (69%) at the e-nd of experiment (P

ObjectiveTo investigate the effect of scalp point penetration combined with rehabilitation training on content of endothelin (ET) and calcitonin gene-related peptide (CGRP) in plasma of patients with acute cerebral hemorrage (ACH).Methods90 ACH patients were randomly divided into the scalp point penetration combined with rehabilitation group (group A), the rehabilitation group (group B) and control group (group C) with 30 cases in each group. The radioimmunoassay was adopted to determinate the content of ET and CGRP in plasma of patients.ResultsAfter treatment, contents of ET and CGRP of all patients were decreased significantly (P<0.01), but group A and group B had a significant difference compared with the group C (P<0.01), and there was also a significant difference between the group A and group B.ConclusionThe scalp point penetration combined with rehabilitation training can regulate the content of ET and CGRP in plasma and make them under a dynamic balance.

Objective To report a new surgical approach (modified anconeus flap approach) in which the anconeus and part of triceps are reflected in the treatment of distal intercondylar humerus fracture (AO type C).Methods To design the modified anconeus flap approach,the anatomy of the distal tendon of the triceps brachii and the anconeus was studied using 15 cadaveric adult specimens (30 sides).The new surgical approach was compared with the triceps-reflecting anconeus pedicle (TRAP) approach in terms of the area of exposure at the distal humeral articular surface.Furthermore,the new surgical approach was applied in 16 patients who had been treated for intercondylar humerus fracture (AO type C) from May 2005 to May 2013.The clinical outcomes were evaluated using the Mayo elbow performance score (MEPS) and Broberg-Morrey scoring systems.Results The blood supply and innervation of the anconeus was interrupted minimally during incision along the radical edge of triceps tendon.The area of exposure at the distal humeral articular surface provided by the part triceps and anconeus reflecting approach and the medial humerus approach was 42.66％ ± 0.03％ at the elbow flexion from 0° to 50°.This was significantly smnaller than that provided by the TRAP approach (46.11％ ±0.03％) (P ＜0.05).Of the 16 patients,15 obtained complete follow-ups from 6 months to 4 years(average,16.5 months).The mean MEPS at the last follow-up was 90.5 points (range,from 82 to 93 points),with 10 excellent and 4 good cases and one poor case.The Broberg & Morrey score system showed 11 patients with no articular cartilage degeneration (level-0),3 patients with level-1 degeneration,and 2 patients with level-2 degeneration.Conclusion The modified anconeus flap approach proposed in the present study provides clear surgical vision and needs no olecranon osteotomy or olecranon dissection or ablation of the major triceps brachii tendon for intercondylar humerus fractures,thereby leading to early active motion and satisfactory clinical outcomes.

Objective To investigate the clinical data and laboratory features of acute megakaryocytic leukemia transformed from idiopathic myelofibrosis after 26 years in one case and the prognostic factors of myelofibrosis.Methods A case of acute megakaryocytic leukemia (M7) transformed from idiopathic myelofibrosis after 26 years was reported,and the clinical data was analyzed.Bone marrow cytology,cytogenetic and mutation detection in JAK2V617F were detected before and after transformation.Standard chemotherapeutic protocols including idarubicin plus cytarabine (IDA),homoharringtonine and cytarabine (HA),mitoxantrone and cytarabine (MA),pirarubicin plus cytarabine (TA) sequential therapies were performed.Results JAK2V617F mutation and normal karyotype were found before and after the transformation.This patient was treated with standard chemotherapeutic protocols of IDA,HA,MA and TA sequential therapies until getting complete remission,and he lived well till now.Conclusions Chromosome karyotype is related to the prognosis of IMF.Acute megakaryocytic leukemia (M7) with the normal karyotype transformed from the IMF can achieve complete remission by rational consecutive chemotherapy.

[Objective]To explore the MRI features of the mucinous breast carcinoma and the correlation with biological prognos?tic factors.[Methods]MRI features of 35 pure and 15 mixed mucinous carcinomas were retrospectively analyzed. MR images were reviewed for shape,margin,the signal intensity,enhancement patterns of tumors and DWI features. All the patients were detected by immunohistochemical staining with expression of ER,PR,CerbB-2,Ki-67 and Her-2. Correlations between the pure and mixed mucinous breast carcinoma and prognostic factors were analyzed.[Results]16 oval masses(16/35,45.7%)and 10 circular masses (10/35,28.6%)were found in 35 pure mucinous breast carcinomas with clear boundary(26/35,74.3%)and lobulated shape(31/35,88.6%);9 irregular masses(9/15,60%)were found in mixed mucinous breast carcinomas with unclear boundary(13/15, 86.7%). Very high signal intensity on T2-weighted images was found in 33 pure mucinous carcinomas(33/35,94.3%)and 11 mixed mucinous carcinomas showed mixed signal intensity(11/15,73.3%). Early enhancement rate was(114.7 ± 9.1)% for pure muci?nous carcinomas and(165.6 ± 14.3)%for mixed mucinous carcinomas. 28 pure mucinous tumors demonstrated persistent enhancing pattern on time-signal intensity curve ,7 pure mucinous tumors demonstrated plateau pattern and 7 mixed mucinous carcinomas showed plateau pattern and washout pattern respectively. Mean ADC value was(1.91 ± 0.06)×10-3 mm2/s for pure mucinous carcino?mas and(1.13±0.08)×10-3mm2/s for mixed mucinous carcinomas. There was significant difference with morphology,boundary,T2WI signal,early enhancement rate,time-signal intensity curve,ADC value between pure and mixed mucinous breast carcinoma(P <0.05). There was significant difference between pure and mixed mucinous breast carcinoma with Her-2 and Ki-67 expression(P <0.05).[Conclusion]MRI could identify PMBC and MMBC from the shape,the signal intensity,dynamic enhancement and ADC val?ue,and PMBC had distinctive MRI features. The prognosis of MMBC is worse than that of PMBC form correlation between biological prognostic factors and mucinous breast carcinoma.
