In recent years,tumor immunotherapy has attracted more attention because of its remarkable curative effect in patients with advanced cancer,but often accompanied by immune related adverse events.Understanding the immune related adverse reaction rate,possible mechanism and adverse reaction evaluation criteria and treatment principle of the immune checkpoint inhibitors such as Ipilimumab,Nivolumab and Pembrolizumab,has important significance for the treatment of malignant tumor.

Objective To elevate the efficacy and complications of partial splenic embolization(PSE) using the alginate microglobe(AMG) as embolic material for hypersplenism in cirrhosis.Methods 42 patients with hypersplenism and cirrhosis were treated by PSE,AMG of 250～450 ?m were injected into the arteries of inferior splenic pole,the embolization degree was ranging from 40% to 70%.Results 42 times of embolization were performed in 42 patients,after operation, 35 patients had fever and lasted for 3~15 d,38 patients had abdominal pain,of them, 27 patients needed treatment with analgesic.Treatable a little hydrothorax appeared in 6 ,and no serious complication occurred.WBC and PLT counts were increased 24 hour later(P

Cytokine-induced killer(CIK)cells are characterized by rapid proliferation, high and broad anti-tumor activities and mild toxicities. Some clinical trials demonstrate that the infusion of a large amount of CIK cells enhances the auto-immune of function in patient, which might help to clean up the remaining tumor cells and minor metastatic tumors and delay the recurrence of tumor with improved curative effects.

Skin toxicities are the most common adverse effects of epidermal growth factor receptor inhibitors(EGFRI).It can result in significant physical and psyehological discomfort,and even leads to interruption or dose modification,and consequently affect the curative effect. Nowadays this adverse effect has attracted lot of attention.It is proposed that clinical management and treatment measures for skin toxicities should be further studied to improve the patients life quality,and guarantee the continuity and best curative effect of the treatment.But more researches on the pathogenesis and its prognostic significance are still expected.

Triple-negative breast cancer ( TNBC ) is a subtype of breast cancer,and it is characterized by an aggressive clinical course with a poor prognosis.Treatment for TNBC has attracted much attention in recent years,however,there is no standard treatment for TNBC in clinical setting.The pCR rates of neoadjuvant chemotherapy in TNBC ranges from 12％ to 48％ in the current published data,and it is higher than that in other types of breast cancer,however,the fluctuating range of the TNBC ’s pCR is large in literature.Although the administration of adjuvant chemotherapy for early TNBC is controversial,the regimen without anthracyclines is reported to be suitable for early TNBC patients.Standard cytotoxic agents including taxanes and anthracyclines are still the main choices for TNBC salvage treatment,and the combination with gemcitabine or capecitabine may improve the overall survival.Poly (ADP-ribose) polymerase (PARP) is a new molecular target for TNBC in ongoing studies.Further research on the target-inhibitors such as BSI-201and Olaparib will provide more effective choices to clinical treatment.

Recent studies suggest that astrocyte elevated gene 1 ( AEG-1 ) is almost highly expressed in all types of malignant solid tumors and correlates with poor prognosis,which becomes a prognostic marker for many kinds of tumors.As a strongly basic protein,AEG-1 possesses a transmembrane domain and multiplenuclear localization signals.It is present in the cell membrane,cytoplasm and nucleus.As an oncogene,AEG-1 palys an important role in a virety of malignant biological behaviors of cancer,which range from cell proliferation,apoptosis,migration,adhesion,invasion to tumor angiogenesis and chemotherapy resistance.Its critical role in tumor genesis and progression has made it a potential therapeutic target.

Thioredoxin-related protein 14 (TRP14),a new member of Trx family,is a novel disulfide reductase with conservative CPDC motif.Its structure and function are comparable to Trx,which is the representative member of Trx family.However,there are many differences.When tumor necrosis factor-α (TNF-α) induced cells to produce the active oxygen,TRP14 can change oxidatin state of dynein light chain(its substrate),act as a sensor of the intracellular redox state to regulate NF-κB signaling pathways induced by TNF-α,MAPK and apoptosis signaling pathways.

Objective To evaluate the effect of surgical treatment of hypertensive intracerebral hemorrhage (HICH) through a straight incision and keyhole minimally invasive craniotomy. Methods According to the location of the hematoma revealed by preoperative CT scans, a straight skin incision was made 4～5 cm in length, and then a keyhole craniotomy 2 cm in diameter was performed. The underlying cortex was incised the hematoma was exposed and removed under microscope. Results The hematomas were thoroughly cleared in 17 cases. The clearance rate was 90% in 18 cases and 80% in 4 cases. Re-hemorrhage occurred in 2 cases after operation. A total of 35 cases was followed for 0.5～3 years (mean, 2.1 years). The quality of life was assessed by activity of daily living (ADL) classification, which revealed 9 cases of grade 1, 12 cases of grade 2, 9 cases of grade 3, 4 cases of grade 4, and 1 case of grade 5 at the 6th postoperative month. The mortality of this series was 10.3% (4/39). Conclusions Straight incision keyhole minimally invasive craniotomy is a rapid, effective, and safe technique for the removal of hypertensive cerebral hemorrhage. The method herein provides an effective decompression of hematoma, with low recurrence rate and good prognosis compared with conventional surgery.

Objective To understand the environmental lead pollution status in Tongzhou and the biological burden of lead in children living in the lead polluted area.Methods The 353 pupils aged 7-14 years were randomly selected in Zhangzhishan town central elementary school that was near to steel wire factories,283 pupils were selected as the control by using the same methods in an elementary school around where there is no any steel wire factory.Every students were investigated by questionnaires,meanwhile their hair were collected to determine lead with ASS method.Results In the polluted area group,hair lead of 77 pupils exceeded the normal level,the median was 4.437 ?g/g,the rate of exceeding the normal level(≤10 ?g/g)was 21.81%,and 65 pupils with lead poisoning related symptoms(18.41%).In the control group,the median was 3.965 ?g/g,the rate of exceeding the normal level was 11.31%,38 pupil with lead poisoning related symptoms(13.43%).After controlled the passive smoking confounder,the difference of hair lead level between these two groups was still significant(P

Objective To study the establishment methods of virtual three-dimensional cerebral aneurysm models by using three-dimensional moulding software.Methods The virtual model including the cerebral arteries and the aneurysms were established by using the three-dimensional moulding software of 3D Studio MAX R3 in 20 cases of normal cerebral DSA image and 216 cases of cerebral aneurysms DSA image as the original.Results ①In comparison with DSA image,the virtual cerebral arteries possessed similarity in appearance,and had a benefit for understanding the vascular three-dimensional spatial relation in visual sense.The virtual cerebral arteries could display the virtual guide wire and catheter in semitransparent.The several models of different variant anatomy could be established easily based on the copy files of the virtual cerebral arteries model;②In comparison with DSA image,virtual cerebral aneurysm could display the location of development,direction of growth and feature of appearance correctly.The several aneurysms models of different location,direction of growth and appearance could be established easily based on the copy files of the virtual cerebral aneurysms model.Conclusion The virtual three-dimensional cerebral aneurysm models that were established by the software method can display the three-dimensional spatial relation of the cerebral arterial system and aneurysmal shape distinctly,and would be useful in assisting morphology study and guiding clinical work.
