Objective Analysis of nitroglycerin combined with predictive nursing in the clinical application of coronary heart disease patients. Methods From January 2015 to December 2016, 200 patients with coronary heart disease were treated with angina pectoris. The patients were randomly divided into observation group and control group (100 cases). The control group was treated with routine nursing mode, and the patients in the observation group were treated with predictive nursing mode. The differences of hospitalization time and quality of life scores between the two groups were observed. The anxiety and depression of the two groups were observed before and after treatment, and the satisfaction of the two groups was observed. Results The scores of hospitalization and quality of life in observation group were better than those in control group (P<0.05). There was no statistically significant difference between SAS score and SDS score before treatment, but SAS score and SDS score of observation group were significantly lower than those of control group (P<0.05). The satisfaction degree of the patients in the observation group was better than that in the control group (P<0.05). Conclusion Predictive nursing has a good effect in the clinical nursing of patients with coronary heart disease and angina pectoris. It can effectively improve the patients' anxiety and depression, shorten the hospital stay and improve the quality of life. It is worth to be used in clinical practice.

Objective To investigate the effects of Arctigenin ( ATG ) on concanavalin ( ConA )-stimulated cell proliferation and cytokine secretion in mouse spleen cells, and its possible mechanism. Methods The toxicity of ATG on mouse spleen cells was determined by MTT assay. The inhibition of proliferation was investigated by tritiat-ed thymidine incorporation method. Secreted cytokines (IFN-γand IL-2) were analyzed by ELISA. The associated proteins and phosphorylation levels of mTOR pathway ( mTOR/P70 S6 K/Akt/AMPK/Raptor ) were detected by Western blot. Results ATG had no significant toxicity to mouse spleen cells. ATG significantly inhibited mouse primary spleen cells proliferation induced by ConA. ATG suppressed IL-2 and IFN-γ production of mouse spleen cells in a concentration-dependent manner. ATG remarkably suppressed the phosphorylation of mTOR and P70S6K, and enhanced the phosphorylation of upstream AMPK and Raptor, while the phosphorylation of Akt did not change significantly. Conclusion ATG markedly suppresses the proliferation of mouse spleen stimulated by ConA cells and secretion of IFN-γand IL-2 , which may be correlated to the abilities of enhancing the phosphoryla-tion of AMPK and Raptor, inhibiting the phosphorylation of mTOR and P70S6K.

Atypical teratoid/rhabdoid tumor of the central nervous system has aggressive growth with high potential CSF dissemination and frequently affects very young children.The tumor contains rhabdoid cells and primitive neuroectodermal,malignant mesenchymal and epithelial elements.Immunohistochemistry is helpful in differentiating atypical teratoid/rhabdoid tumor from primitive neuroectodermal tumor/medulloblastoma.Atypical teratoid/rhabdoid tumor is cytogenetically characterized by monosomy 22 or deletion of chromosome band 22q11.2.Intensified therapy combined with surgical resection has been suggested for its treatment.Due to the secondary cystic/necrotic changes and hemorrhage,the imaging features of the tumor are variable.

Objective To explore the associated factors influencing the prognosis of upper limb function and ability of activities daily living(ADL)in stroke patients with left side hemiplegia.Methods 64 stroke patients with left side hemiplegia were treated regularly last for 1 month.At admission,the assessment procedure for cognitive function were performed with scales of Mini-Mental State Examination(MMSE),Loewenstein Occupational Therapy Cognitive Assessment(LOTCA),Motor Impersistence(MI),Schenkenberg Line Bisection Test.Brunnstrom stage,Modified Barthel Index(MBI),Ueda,Bin Hemiplegic Finger Function Assessment Scale,Upper Limb Function Assessment Scale were graded for the upper limb function and ADL ability before and after training.The multinominal logistic regression analysis was used to analyze the relationship between those factors and the upper limb function and ADL ability.Results The extent of resumption of upper limb function of patients was positively correlated with the ability of formal operational thinking(P<0.01)in LOTCA score before training.However,the extent of resumption of hand was negatively correlated with MI score before training(P<0.01).The extent of resumption of the hand practicability was positively correlated with the ability of operational thinking and score of ADL in LOTCA before training(P<0.01).The extent of the resumption of ADL was positively correlated with the ability score of operational thinking in LOTCA and diseased region.It was negatively correlated with the score of Schenkenberg line bisection(P<0.01).Conclusion The ability of operational thinking in LOTCA before training and the scores of Schenkenberg line bisection,ADL and MI are helpful in prognosis for the upper limb function in stroke patients with left side hemiplegia.

Objective To investigate the value of diffusion weighted magnetie resonance imaging and apparent diffusion coefficient (ADC) value in the diagnosis of pancreatic cancer.MethodsThe clinical data of 36 patients with pancreatie cancer who were admitted to the Wuxi No.2 People's Hospital from March 2009 to June 2011 were retrospectively analyzed,and the clinical data of 30 healthy volunteers were collected.All candidates received diffusion weighted magnetie resonance imaging examination.The signal intensity ratios ( SIRs ) of the cancer and the pericancerous tissues in the T1 weighted-images (T1WI),T2 weighted-images (T2WI)and diffusion weighted-images (DWI) were compared by using one-way analysis of variance.The ADC values of the cancer and the paricancerous tissues were compared using the paired t test.The differences of the ADC values of the cancer and pericancerous tissues compared with those of healthy individuals were analyzed using an independent sample t test.ResultsThe accuracy rate of preoperative magnetic resonance imaging examination was 92％.The relative SIRs were 0.203 ± 0.190 in the T2 WI,0.399 ± 0.201 in the T1 WI and 0.579 ± 0.291 in the DWI,respectively,with no significant differences across the 3 kinds of images (F=5.92,6.15,6.83,P ＜ 0.05 ),while SIRs of the T1 WI and DWI were significantly higher than that of the T2 WI ( P ＜ 0.05 ).There was no significant difference in SIRs when comparing T1 WI and DWI ( P ＞ 0.05 ).The mean ADC values of the cancer and pericancerous tissues of the pancreatic cancer patients and the pancreatic tissues of healthy individuals were (1.40±0.24) ×10 3 mm2/s,(1.71 ±0.10) ×10-3 mm2/s and (1.73±0.30) ×10-3 mm2/s,respectively,with significant differences across the 3 modes of images (t =10.54,12.08,P ＜ 0.05).ConclusionDWI can show high quality images of the lesions,and ADC value is helpful in the diagnosis of pancreatic cancer.

Objective To construct HaCaT cell lines stably expressing the wild type human GJB6 gene or its mutant by using a Tet-On lentiviral vector, and to lay an experimental foundation for studies on pathogenesis of hidrotic ectodermal dysplasia. Methods The wild-type human GJB6 gene and its mutant (A88V)were amplified by PCR, and then inserted into the Tet-on lentivirus plasmid to construct recombinant lentivirus vectors. The recombinants were identified by gene sequencing and enzymatic digestion. Cultured HaCaT cells were classified into three groups to be transfected with a negative control lentiviral vector (NC group), the lentivirus vector expressing the wild-type human GJB6 gene (WT group), or the lentivirus vector expressing the mutant human GJB6 gene (MU group). Puromycin was used to select HaCaT cell clones stably expressing the GJB6 gene which encodes the connexin 30 (Cx30)protein. The selected HaCaT cell clones were cultured with or without tetracycline for 48 hours, thereafter, real-time PCR(RT-PCR) was performed to detect GJB6 gene mRNA expression, Western-blot analysis to measure expressions of Cx30 and FLAG-tag proteins, and cell counting kit 8 (CCK8)assay to evaluate cellular proliferative activity. Results Enzymatic digestion and gene sequencing showed that recombinant lentivirus plasmids were successfully constructed. RT-PCR showed evidently increased mRNA expression of the GJB6 gene in stably transfected HaCaT cells. Moreover, the expression abundance of the GJB6 gene was 112.369 times higher in the WT group induced by tetracycline than in that without tetracycline treatment (P < 0.05), and 2.249 times higher in the MU group induced by tetracycline than in that without tetracycline treatment (P < 0.05). Western-blot analysis showed that Cx30 and FLAG-tag proteins were stably expressed in the WT group and MU group after induction with tetracycline, while neither of them was observed in the WT group or MU group without tetracycline treatment, or in the NC group. Significant differences were noted in cellular proliferative activity (expressed as the absorbance value at 450 nm)between the MU group with and without tetracycline treatment and between the WT group with and without tetracycline treatment at 4, 8, 12, 24, 36 and 48 hours (all P <0.05), but not between the NC group with and without tetracycline treatment at any of the above time points (all P >0.05). Conclusion HaCaT cell lines which stably express the wild-type GJB6 gene or its mutant(A88V)are successfully constructed.
