Objective To analyze and discuss the causes of late dysfunction following the mismanagement of acute Lisfranc fracture- dislocations in light of the latest advancement in this field. Methods From March 2000 to February 2005, we treated 34 cases of old Lisfranc fracture- dislocation. 24 cases were treated with open reduction and internal fixation, and 10 with arthrodesis. Results According to the AOFAS for midfoot, 2 cases scored 50 to 60, 4 cases scored 60 to 70, 5 cases scored 70 to 80, 18 cases scored 80 to 90 and 5 cases scored 90 to 100. Conclusions Since the incidence of Lisfranc fracture- dislocation tends to increase, clinic orthopedists must take great care to examine the midfoot strain lest a case should be overlooked. The late complications are related to poor reduction, inadequate fixation, or inadequate postoperative immobilization. For most patients, open reduction and internal fixation within 6 weeks after injure is preferred. The cannulated screws are simple and stable for fixation of lateral and medial columns, and screw removal should be done 3 to 4 months after surgery to prevent recurrent diastasis and screw breakage.

Purpose: To evaluate the efficacy and the side effects of 3 D-conformal radiotherapy for malignant thoracic tumor. Methods: Between September 1999 and August 2002, 36 patients with malignant thoracic tumor were treated with 3D-conformal radiotherapy. Twenty-two patients had primary lung cancer, 12 patients had metastatic lung cancer, and 2 patients had malignant mediastinal tumor. All 36 patients were pathologically confirmed. Squamous cell carcinoma 16 cases, adenocarcinoma 15 cases, small cell carcinoma 2 cases, embryonal carcinoma 1 case, malignant thymoma 1 case and sarcoma 1 case. For the primary tumor, conventional radiotherapy was first used to 50Gy/25F/5W, followed by 3D-conformal radiotherapy 16-20Gy(4Gy per fraction, 3 fractions per week) with MLC or cone from 5 ~6 non coplanar or coplanar static ports. For metastatic tumor, using arc therapy to only 28-40Gy(4Gy per fraction, 3 fractions per week, 7-10 fractions) with cone from 1 ~ 4 arcs. Tumor volumes from 1. 85 cm3 to 104. 61 cm3 with a median of 24. 96 cm3 in 3D-CRT. Results: To evaluate the effects, thoracic CT scan was taken two months after completion of 3D-conformal radiotherapy. In 34 evaluated patients, 13 cases obtained CR, 14 PR, 5 NC, and 2PD. The overall 1 and 2-year survival rates were 74. 1% and 38.4%. Toxicity consisted of grade 1 acute radiation pneumonitis in 17 patients, grade 2 in 10 patients, grade 3 in 1 patients, and 2 patients dead of radiation pneumonitis ( with non coplanar technique), late complication was radiation pulmonary fibrosis, grade 1 in 20 cases, grade 2 in 8 cases. Conclusions: 3D-conformal radiotherapy as complement of conventional external beam radiotherapy for malignant thoracic tumor can obtain better short-term effects, although the survival is yet to be investigated. But attention must be given to the irradiation technique, the irradiation volume should not be too large and beams angles appropriately adjusted to avoid excessive irradiated volume in normal lung.

Unilateral enlargement of the vestibular aqueduct (EVA)is a relatively rare disease. Bilateral EVA was found to be more common than unilateral EVA. There are significant differences in clinical features and molecular etiology between unilateral EVA and bilateral one. This article reviewed related researches of the unilateral EVA in clinical characteristics, molecular etiology and pathogenic mechanism.

Conclusion The successful construction of HLA-Cw*0602 gene will lay the foundation for development of transgenic animal models of psoriasis.

OBJECTIVE:To evaluate the effects of 3 kinds of serum containing blood-activating and stasis-eliminating TCM compound formulas on aggressive behavior,Janus kinase (JAK)/signal transduction and transcriptional activator (STAT) pathway of glioma U251 cells. METHODS:Rats were randomly divided into normal saline group (5 mL/kg),Taohong Siwu decoction group(5.7 g/kg),Xuefu Zhuyu decoction(8.5 g/kg)and Didang decoction(2.8 g/kg),calculated by crude drug,intragastrically administrated once a day,for 10 d. 10% drug-containing serum culture medium was prepared after 2 h of last administration. After 10% drug-containing serum culture medium intervening U251 cells for 1 week,Transwell method was conducted to detect the cell invasion rate, Western blot was adopted to detect the metal matrix protease 2 (MMP-2), MMP-9, phosphorylated JAK2 (p-JAK2),phosphorylated STAT3(p-STAT3)protein expression;and real-time fluorescence quantitative polymerase chain reaction method was used to detect MMP-2,MMP-9 mRNA expression. RESULTS:Compared with blank serum,Xuefu Zhuyu decoction drug-containing serum can reduce cell invasion rate (P<0.05),decrease the MMP-2,MMP-9 mRNA and its protein expression, and p-JAK2,p-STAT3 protein expression in cells (P<0.05 or P<0.01),while there was no significant difference in above-men-tioned indexes in Taohong Siwu decoction drug-containing serum group and Didang drug-containing serum group(P>0.05). CON-CLUSIONS:In the 3 kinds of blood-activating and stasis-eliminating TCM compound formulas,Xuefu Zhuyu decoction shows sig-nificant invasive effect on inhibiting U251 cells;the mechanism may be related to inhibiting the activation of JAK2/STAT3 signal pathway and decreasing MMP-2,MMP-9 gene and protein expressions.

Objective To summarize the clinical characteristics and evaluate the feasible treatments of primary breast lymphoma (PBL).Methods The clinical data of 34 PBL patients (age 24-79 years) who were treated in our hospital between April 2006 and December 2013 were reviewed.Of these 34 patients, 18 had stage ⅠE PBL and 16 had stage ⅡE PBL.Pathological types included diffuse large B cell lymphoma (29 patients), anaplastic large cell lymphoma (2 patients), marginal zone lymphoma (2 patients), and mantle cell lymphoma (1 patient).Two patients underwent surgery, four patients received chemotherapy alone, five patients received chemoradiotherapy, fourteen patients underwent surgery plus chemotherapy, and nine patients underwent surgery plus chemoradiotherapy.The 5-year overall survival (OS) and progression-free survival (PFS) rates were determined by the Kaplan-Meier estimator.Results During follow-up, 26 patients were alive without lymphoma and 8 patients had died by the end of follow-up (7 died from lymphoma and 1 died from chemotherapy-related hepatic failure).Among the 6 patients who relapsed, 5(83.3%) had recurrence within the first 2 years of treatment.In particular, 1 patient who had bilateral breast involvement developed left breast relapse after bilateral mastectomy and chemotherapy, 2 patients had bone marrow metastasis, 1 patient had lung and mediastinal lymph node metastases, and 2 had skin relapse.The 5-year OS and PFS rates of all patients were 75% and 75%, respectively.Conclusions Since PBL is a rare malignancy, its overall prognosis is fair and the incidence of local relapse is low with chemotherapy alone or in combination with other treatments.However, further studies on the development of more effective treatments will be required for patients who have failed the existing treatments.

Objective To investigate the effect of salmeterol/fluticasone (SM/FP) on serum inflammatory factors in the treatment of bronchial asthma in children.Methods 80 children with bronchial asthma from January 2015 to October 2015 in department of pediatrics of first affiliated hospital of Zhejiang Chinese medicine university were selected and randomly divided into two groups.The control group were given routine clinical treatment, the experimental group were treated on the basis of the control group with salmeterol/fluticasone (SM/FP), for 4 weeks.The serum IL-2, IL-4, IFN-α, T-lymphocyte subsets and clinical efficacy between the two groups were compared.Results Compared with control group, the serum levels of IL-2 and IFN-γin experimental group were higher, IL-4 in experimental group was lower ( P <0.05 ); the serum CD3 +T, CD4 +T and CD4 +T /CD8 +T levels in experimental group were higher, the serum CD8 +T was lower than those in control group (P<0.05); the total efficiency of the experimental group (92.5%) was significantly higher than that of control group (75.0%) (P<0.05).Conclusion The salmeterol/fluticasone (SM/FP) has the good efficacy in the treatment of bronchial asthma in children, which could effectively regulate T lymphocyte subsets proportion and the level of cytokines.
