Talus necrosis is difficult to cure in clinical practice and how to treat it remains con-troversy.Microsurgical methods provide a new path for curing the disease and good curative effects have been achieved according to the literature.This article reviewed microsurgical treatments for talus necrosis in recent years and it may provide references for clinical practice.

Leptomeningeal metastasis (LM),with a high omission rate in diagnosis in approximately 5 ％～8 ％ of all patients, is increasingly recognized as a lethality complication. The diagnosis of LM remains challenges,but commonly can be established by CSF cytology or by definitive neuroimaging. Although a combination of focal radiotherapy,intrathecal chemotherapy,and systemic chemotherapy may be necessary to achieve optimal treatment of patients, but prognosis is unacceptable and therapy remains palliative in most patients.

The course of functional laboratory science is the bridge between classroom and clinical practice.In functional laboratory science teaching,we should pay attention to features of nursing care,focus on training compassion,clinical awareness,collaboration ability,practical skills for nursing students and combine the reform of functional laboratory science teaching with cultivation of professional quality for nursing students.

Purpose Protein is the main influencing factors for diffusion weighted imaging (DWI) signals and apparent diffusion coefficient (ADC), it results in hyperintensity on DWI and low ADC, but not fully matched in clinic. This paper aims to investigate the effect of protein type and concentration on the signal intensity (SI) and ADC of DWI. Materials and Methods Different concentrations of albumin, globulin solution and the mixed solution were created in vitro. DWI was performed on GE 1.5T superconducting nuclear MRI system. Results ① There was a linear negative correlation between the ADC value and the concentrations of protein solution (at 37℃, ra= - 0.849, Pa<0.05; rg= - 0.843, Pg<0.05; at 40℃, ra= - 0.894, Pa<0.05; rg= - 0.819, Pg<0.05);there was a linear positive correlation between the SI of DWI and the concentrations of the albumin solution (at 37℃, r=0.753, P<0.05; at 40℃, r=0.845, P<0.05). There was no correlation between the SI of DWI and the concentrations of the globulin solution (at 37℃, r= - 0.222, P>0.05; at 40℃ , r= - 0.270, P>0.05). ② SI of the albumin solution was significantly higher than the globulin solution at the same concentration and temperature (t=3.96, P<0.001); the ADC values were not statistically different between the albumin and the globulin solution (t=0.61, P>0.05). Conclusion The nature of the cystic fluid can be understood preliminarily through quantitative analysis of the cystic fluid DWI and ADC values, so as to provide theoretical basis for the qualitative diagnosis of cystic lesions in vivo.

Objective To study the anatomic characteristics of the infraorbital ethmoid cells on muhislice CT(MSCT)and explore the relationship between the infraobital ethmoid cells and mueosal swelling of sinuses.Methods Two hundred sixty patients(520 sides) of consecutive axial scans by GE HisDeed VCT and the multiplunar reformation(MPR),virtual endoscopy(VE)reconstruction images by GE AW 4.2 workstation were reviewed retrospectively.The following CT features were assessed:(1)the anatomic characteristics of the infraobital ethmoid ceils,including the frequency of identification,origin,classification.(2)presence of mucosal swelling of sinuses,(3)the maximal transversal diameter of the inflraobital ethmoid cells in ostium of maxillary sinus(perpendicular to the uncinate process),and the diameter of the ostium of maxillary sinus,(4)presence of infraobital ethmoid ceils inflammatory findings and a contact between the mucosal surface of the ostium of maxillary sinus.The results were analyzed by using Chi-square test and logistic regression analysis with the statistical software SPSS 11.5.Results (1) UniLateral infraobital ethmoid cells were f10und in 68 patients(26.1%),and bilateral infraobital ethmoid cells were found in 81 patients(31.2%).Infraobital ethmoid ceHs were found in 230 sides on left Bide (120 sides)and right side(110 sides).(2)Infraobital ethmoid cells originated from the anterior ethmoid cells in 124 sides(53.9%)and from posterior ethmoidal cells in 62 sides(27%),originated from both the anterior ethmoidal cells and the posterior ethmoidal cells in 44 sides(19.1%).(3)The classification of the infraobital ethmoid cells included three types.Infraobital ethmoid cells with different origination differed significantly in theirtypes(x2=193.433,P<0.01).Most ofthe infraobital ethmoid cells originated from tlle anterior ethmoidal cells were type Ⅰ(160 sides),while the type Ⅱ(48 sides)and Ⅲ(45 sides) frequently originated from the posterior ethmoidal ceHs(4)The mueosal swelling of sinuses,were found in 165 sides in presence of infraobtial ethmoid cells and 192 sides in absence of infraobtial ethmoid cells.The presence of infraobtial ethmoid cells had no effect on mucosal swelling(X2=1.824,P>0.05).The maximal transversal diameter of the infraobital ethmoid cells in ostium of maxillary sinus did not differ significantly between the cases with or without mucosal swelling of sinuses(t=0.273,P>0.05).and the diameter of the ostium of maxillary sinus were not significantly related with mucosal swelling of sinuse8 (Wald=2.534,P>0.05).Presence of infraobital ethmoid cells inflammatory findings (Wald=10.817. P<0.01,OR=4.125)and a contact between the mucosal surface of the ostium of maxillary sinus (Wald= 6.640,P<0.01,OR=3.728)were significantly related to mucosal swelling of 8inuses. Conclusions (1)MSCT scan could clearly demonstrate the detailed information of infraobital ethmoid ceIIs.(2)The presence of infraobtial ethmoid cells Was not a risk factor for chronics sinusitis. When we assess inflraobtial ethmoid cells as a possible etiologic factor in chronics sinusitis we should observe presence of infraobital ethmoid cells inflammatory findings and a contact between the mucosal surface of the ostium of maxillary sinud.

BACKGROUND:The severity of tissue injury varies with the causes of the amputated finger. Simple soft tissue, vessels or nerves injury could be easily repaired by adjacent finger flap or abdominal flaps. However, these treatments are short of long repair time, reoperation and unsatisfactory appearance of the finger. OBJECTIVE:To investigate the efficiency of Flow-through flap from the fibular side of great toe to repair skin and soft tissue defects in digital replantation. METHODS:From January 2011 to October 2013, Flow-through flap from the fibular side of great toe was applied to repair soft tissue injury in digital replantation for 11 cases (8 males and 3 females, age ranged from 23 to 42 years. Skin defects ranged from 2.0 cm ×1.5 cm to 4.0 cm×2.2 cm; vascular defect ranged from 1-3 cm, 1.5 cm averagely; and the flap size ranged from 2.2 cm×1.7 cm to 4.5 cm×2.5 cm. RESULTS AND CONCLUSION:The folow-up time of al patients was 6-18 months. Digital replantation was successful in al the 11 cases. Ten cases were healed by first intention, and one case was gradualy rescued after dressing change. Patients were satisfied with the flap and the peripheral sensation. The peripheral discrimination of patients was 4 to 10 mm. The fingers functioned wel in flexion and extension. Of the 11 cases, 9 cases were valued excelent and 2 cases was rated as good, according to the upper extremity function evaluation standard of the Hand Surgey Branch of Chinese Medical Association. Flow-through flap from the fibular side of great toe is an ideal method to repair skin soft tissue and vascular defects in digital replantation.

Objective To investigate the value of application of magnetic resonance imaging (MRI) in diagnosis and treatment of leptomeningeal metastases from malignant solid tumors.Methods A retrospective analysis was conducted depend on the radiological data of 63 patients who had been diagnosed as leptomeningcal metastasis of malignant solid tumors.Results All patients received brain MRI examination.26 patients underwent cervical or lumbar spine MRI examination.The MRI images showed nodular enhancement in the gyri and sulci,leptomeningeal linear enhancement,dura mater thickening and enhancement,ependymal enhancement,intraventricular metastasis,intraspinal metastatic nodules,communicating hydrocephalus,subdural hydroma and negative imaging.Ncuroimages of ependymal enhancenent,intraventricular metastasis and intraspinal implantation metastasis appeared in 5,7 and 9 patients with small cell carcinoma,respectively,which were higher than that of the other pathological types (P =0.002,P =0.009,P ＜ 0.000 1).Seizure occurred in 7 patients after intrathecal chemotherapy,of which 5 patients had pia mater linear enhancement.Among 33 patients treated with radiotherapy combined with intrathecal chemotherapy,3 patients had poor prognosis,of which 2 patients had negative imaging findings.The conditions of 25 patients were improved obviously after treatment,of which 21 patients showed different imaging remission in MRI re-examination.Conclusions The contrast MRI has an important assistant effect in diagnosis of leptomeningeal metastasis of malignant solid tumors.The MRI findings and clinical features are related with the pathological types.The pia mater linear enhancement indicates a high possibility of seizures after inthathecal chemotherapy,and it suggests that the preventive treatment should be given for such patients.MRI is not applicable to evaluate severity,prognosis and curative effect of the disease.
