Objective To explore the diagnosis and treatment for primitive neuroectodermal tumor of the adrenal gland.Methods The clinical data of 2 patients with primitive neuroectodermal tumor of the adrenal gland were retrospectively analyzed.Literatures about diagnosis and treatment of primitive neuroectodermal tumor arising from the adrenal gland were also reviewed.Results B type ultrasonography and computer tomography scans showed a cystic and solid soft tissue masses about 3 cm (patient 1) and 15 cm (patient 2) in maximum diameter with rough border.Surgeries were performed successfully in 2 patients.The diagnosis of primitive neuroectodermal tumor arising from the adrenal gland was confirmed by histopathology and immunohistochemistry.During follow up,evidences of tumor recurrence were not found in the first patient.However,the second patient had diffuse retroperitoneal lymph node metastasis 3 months after surgery.Then,the patient died 6 months after surgery.Conclusion The primitive neuroectodermal tumor of the adrenal gland is extremely rare with highly malignant and poor prognosis.Its diagnosis is based on histopathology and immunohistochemistry.Multimodal therapeutic regimens including surgery,combination with chemotherapy and radiotherapy were recommended.

Graphene/Room temperature ionic liquids ( GN/IL ) nanocomposite was prepared by grinding graphene and ionic liquid 1-butyl-3-methylimidazolium bromide ( BMIMPF6 ) which mixed together in appropriate proportion. Atomic force microscopy ( AFM ) was utilized to characterize the formation of the GN-ILs. Due to the synergistic effect between ionic liquids and graphene, the nanocomposite exhibited excellent performance toward H2 O2 reduction. A novel uric acid ( UA) electrochemical sensor was fabricated based on uricase-GN/IL modified glassy carbon electrode. The experimental results showed that the response displayed a good linear response toward UA in the concentration range from 0. 002-4. 5 mmol/L. The corre1ation coefficient was 0. 995 and the detection limit was 0. 85 μmol/L. The easily prepared electrochemical sensor had favorable stability and selectivity and could be applied to the quick determination of UA in human serum, thus providing a new UA detection method for clinical trial.

[Objective]To discuss the effective treatment of complicate intertrochanteric hip fracture.[Method]Thirty-five cases with complicate intertrochanteric hip fracture.The class of fracture,surgery method,operating time,complicatico,union rate of fracture were amounted statisti cally.[Result]All the 35 cases were surgical treated,l 4 cases with PFN(priemeral femur nail),21 cases with DHS(dynamic hip screw)with mean time of operation 1.8 h(1.5~3 h),mean amount of blood loss during operation 300 ml(150~500 ml),mean time in bed 2.4 monthes (1.2~3 monthes),mean following-up time 12 months(6~16months).Thirty-one cases got union,3 cases union time delayed,1 case nounion,union rate was 88.5%.Four cases suffered hip iversion( 11.4%),the screw in the neck removed in 6 cases(8.5%),5 cases feeled pain in hip( 14.2% ).[Conclusion]The complicate intertrochateric hip fracture is a kind of fracture which can not be treated easily.Using PFN and DHS can not control the stability effectively.Additional fixation of the greater trochantar fracture is necessary.Added out-fixation and avoid early bearing are useful.

OBJECTIVE:To investigate the effects of Xuebijing injection on inflammatory factors,oxidation stress level and thrombosis risk in patients with acute non-ST elevation myocardial infarction(NSTEMI). METHODS:A total of 130 NSTEMI pa-tients selected from our hospital during May 2015-Aug. 2016 were divided into control group and observation group according to random number table,with 65 cases in each group. Control group was given routine treatment as lowering blood pressure,lower-ing lipid,anticoagulation and antiplatelet. Observation group was additionally given Xuebijing injection 50 mL,ivgtt,q12 h,on the basis of control group. Both groups were treated for a week. The levels of inflammatory cytokines(TNF-α ,IL-6,IL-10, hs-CRP),SOD,MDA,MMP-9,platelet aggregation rate and fibrinogen were observed in 2 groups before and after treatment. The treatment course,the occurrence of MACE and bleeding event were also recorded. RESULTS:Before treatment,there was no statistical significance in the levels of inflammatory factors,SOD,MDA,MMP-9,platelet aggregation rate or fibrinogen between 2 groups(P>0.05). After treatment,the levels of TNF-α,IL-6,hs-CRP,platelet aggregation rate or fibrinogen in 2 groups were decreased significantly,while the level of IL-10 was increased significantly;the improvement of above indexes in observation group was significantly better than control group. The levels of SOD and MMP-9 in 2 groups were increased significantly,while the level of MDA was decreased significantly. The level of SOD in observation group was significantly higher than control group, while the level of MDA was significantly lower than control group,but the level of MMP-9 was significantly lower than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of MACE (16.92% vs. 20.00%)or bleeding event(4.62% vs. 7.69%)between 2 groups(P>0.05). CONCLUSIONS:Xuebijing injection shows signifi-cant therapeutic efficacy for NSTEMI,effectively inhibits inflammation,and oxidative stress and reduces the risk of thrombosis with good safety.
