Objective To investigate the risk factors for intracranial infection after external ventricular drainage and provide basis for preventing and controlling the drainage-associated intracranial infection. Metheds the clinical data from three hundred sixty-seven cases of ventricular hemorrhage patients were retrospectively analyzed, using Logis?tic regression to screen risk factors of intracranial infection after external ventricular drainage. Results There were 29 cases with intracranial infection and infection rate was 8.19%, 8.04% and 7.32% at ventricle drainage tube indwelling 1-week group, 2-week group and 3 week-group, respectively. Glasgow coma score (GCS) [OR= 2. 569 CI (1.792 3.378) %, P< 0.05), urokinase perfusion (OR= 2.897, 95%CI (1.297 5.061), P< 0.05), cerebrospinal fluid sampling (OR= 3.399, 95%CI (2.705 4.175), P< 0.01] and comorbidities [OR= 3.751, 95%CI (2.032 5.371), P< 0.01] were risk factors for ventricle drainage operation. Conclusion Ventricle drainage tube indwelling 3 weeks is safe. Less use of urokinase perfusion and cerebrospinal fluid sampling and active treatment of comorbidities diseases can reduce the intra?cranial infection incidence of external ventricular drainage after Intraventricular hemorrhage .

Nanobody is a kind of antibody from camel, which misses light chain. Nanobody has the same antigen binding specificity and affinity as mAb. Moreover, because of its small molecular weight, high stability and easy preparation, nanobody has great value of biomedical applications. In this study, we successfully prepared highly pure antiEGFR nanobody in E.coli using genetic engineering techniques. Cell proliferation assay (CCK-8 assay) and migration experiments (cell scratch test and Transwell assay) indicated that the recombinant antiEGFRnano can significantly inhibit the proliferation and migration of endometrial cancer cells. These results provide a new way of thinking and methods for EGFR-targeted therapy of endometrial cancer.

[Objective] To investigate the possible effect of microRNA-374 (miR-374) expression on tumor cells' proliferation and invasion and particular mechanism.[Methods] MiR-374 overexpression lentiviral vector (Lv-miR-374) and a control lentiviral empty vector (LEV) were stably transfected into human glioma U251 and U87 cells,to evaluate the effect of miR-374 on cell proliferation and invasion ability.Target relationship between miR-374 and PTTG were researched by dual luciferase report gene assay.Expression level of correlative signaling pathways of the downstream gene protein was analyzed by Western blot.[Results] We revealed that the overexpression of miR-374 dramatically suppressed glioma cell growth and invasion in vitro.Target relationship between miR-374 and PTTG was confirmed by dual luciferase report gene assay.And decreased protein expression of PTTG,bFGF,AKT,MMP2,and p70S6K was consistent with the effect of miR-374 overexpression.[Conclusion] Decreased miRNA-374 is an unfavorable prognosis marker and promotes glioma cell growth and invasion via direct targeting PTTG.Our findings provide new insights into the role of miR-374 in the development of gliomas,and implicate the potential application of miR-374 in cancer therapy.

ObjectiveTo investigate the correlation between femoral distal medial torsion and patellofemoral joint malalignment and analyze the causes of patellofemoral joint disorders,which provide the new theory with clinical treatment.MethodsFrom May 2007 to June 2009,124 knees(95 cases) with patellofemoral joint disorders were enrolled in this study randomly.Each knee was scanned with CT in dynamic 20° -30° knee flax position.Femoral distal medial torsion angle (FMTA),patellar congruence angle (CA) and patellar tilt angle(PTA) were measured.The correlation between FMTA and CA or PTA was analyzed.Results FMTA < 5° in 25 knees,≥5° in 99 knees,6 knees with trochlear dysplasia who were excluded.FMTA in 93 knees was 16.06° ± 5.68°,CA was 16.40° ± 5.48° and PTA was 19.59° ± 3.32°.The positive correlation was found between FMTA and CA when FMTA > 10°through scatter diagram analysis (r =0.709,P < 0.05 ).The positive correlation was found between FMTA and PTA when FMTA >10°( r =0.652,P < 0.05),the positive trend declined when FMTA > 27°.ConclusionsFemoral distal medial torsion is an important risk factor of patellofemoral joint malalignment.When FMTA > 10°,FMTA and CA,PTA has positive correlation,but the positive tend between FMTA and PTA declines when FMTA > 27°.

Objective To investigate the influence of IL-8 on the tight junction of vascular endothelial cells.Methods Immunofluorescence was used to observe the modality and the distribution of three tight junction proteins (occludin,claudin-5 and ZO-1) of the EA.hy926 cells treated with IL-8 under different concentrations and different times.RT-PCR was used to measure the mRNA expression of these three proteins.Results The results demonstrated that IL-8 could change the distribution of occludin,claudin-5 and ZO-1 in EA.hy926 cells,and the mRNA expression of occludin,claudin-5 and ZO-1 decreased with the increase of IL-8 concentration and treated time.Conclusion The effects of IL-8 on the distribution and the expression of occludin,claudin-5 and ZO-1 are dose and time-dependent.

Focal adhesion kinase (FAK) plays a critical role in the process of cell adhesion and migration by regulating the expression of downstream small G proteins. A kind of focal adhesion kinase (FAK) inhibitor was used to inhibit the phosphorylation of Y397 site of FAK, and scratch wound migration assay was used to examine the effect of FAK inhibitor with different concentrations (0-250 nmol/mL) on the migration of hepatomal cells (Hep G2 cells) at 0, 2, 4, 8 and 24h. Immunofluorescence analysis and Western blot analysis were performed to detect the expression of F-actin and small G proteins Rac1, RhoA and Cdc42 in Hep G2 cells treated with FAK inhibitor for 120 min. The results indicated that the FAK inhibitor can inhibit the migration of Hep G2 cells with a dose- and time-dependent manner. F-actin was down-regulated in Hep G2 cells treated with FAK inhibitor for 120 min, and expression of small G proteins were inhibited at different durations. The inhibition of FAK phosphorylation could inhibit cell adhesion and migration by down-regulating small G proteins. These results suggested that FAK inhibitor can inhibit the migration of tumor cells by blocking FAK phosphorylation. This means that FAK inhibitor can block the metastasis of tumor cells to surrounding tissues. It may be a potential application in the prevention and treatment of cancer.

Chinese Journal of Behavioral Medicine and Brain Science 2018;27(3):272-276
Objective To investigate the relationship with willing acceptance,striving and subjective well-being(SWB).Methods A total of 1800 staff of a general hospital in Changsha were assessed by willing acceptance and striving questionnaire (WASQ) and the brief subjective well-being scale for Chinese citizen (SWBS-cc20).Results (1) The average level of willing acceptance,striving and SWB of hospital staff were 41.71± 13.92,51.45± 17.08 and 84.55±21.48.(2)There were statistically significant differences among SWB in different marital status,educational level,profession,professional title,family per capita monthly income and ages(all P<0.05).(3) The score of SWB in high willing acceptance group was significantly higher than that in low willing acceptance group (t=16.18,P<0.01),while the score of SWB in high striving group was significantly higher than that in low striving group (t=17.39,P<0.01).(4)Willing acceptance and striving had positive correlation with SWB (r=0.697,r=0.700,P<0.01).(5) Willing acceptance (β=0.502,P<0.01) and striving (β=0.490,P<0.01) positively predicted subjective well-being (R2 =0.499,P< 0.01).Conclusions Willing acceptance and striving can improve the level of SWB and promote mental health.
