Objective To study the characteristics and prognostic analysis of 83 cases of pulmonary infection in elderly patients in emergency department.Methods Thirty-eight elderly patients with pulmonary infection from January 2013 to December 2015 in our hospital were retrospectively analyzed.Results The number of neutrophils increased in 56 patients(67.46%), the neutrophil-lymphocyte ratio increased in 69 patients(83.13%), and C-reactive protein increased in 74 patients increased(89.16 %).There was significant difference between C-reactive protein detection and neutrophil count(P<0.05).61 cases(73.49%) were complicated with other diseases.While the effect of a single antibiotic treatment is less effective.Conclusion The early symptoms of pulmonary infection in the elderly are easy to ignore, and often associated with other diseases.C-reactive protein, neutrophil-lymphocyte ratio combined with lung imaging can be more accurate response to the elderly pulmonary infection.Early detection and early treatment, combined use of antibiotics can improve the prognosis.

OBJECTIVETo study on pharmacologic actions on quail hyperlipidemia and atherosclerosis model.

METHODTo duplicate quail hyperlipidemia model by ectogenesis cholesterol and high fat forage, induce to atherosclerosis model, observe influence of sugarcane alkane alcohol to model animals' blood fat level, formation of atherosclerosis plaque, pathological changes of coronary vessels and vascular intimal.

RESULTTC, TG, LDL-C level in blood serum of quail hyperlipidemia markedly decreased after administered sugarcane alkane alcohol by dose of 30, 15, 7.5 mg x kg(-1), proliferation of aorta and brachiocephalic artery tunica intima foam cells was suppressed.

CONCLUSIONSugarcane alkane alcohol has satisfactory pharmacologic actions on hyperlipidemia and atherosclerosis animal model by regulating blood fat.

Objective:To investigate the factors related to recurrent laryngeal nerve invasion in papillary thyroid carcinoma (PTC) with posterior capsular involvment.Methods:The data of 186 PTC patients admitted and operated from Jun 2017 to Jun 2022 were retrospectively analyzed. The invasion of recurrent laryngeal nerve was evaluated on its relation to gender, age, tumor size, Hashimoto's thyroiditis, lymph node metastasis in central region, BRAFV600E gene mutation especially PTC posterior capsular involvement.Results:The recurrent laryngeal nerve was invaded in 30 out of 186 patients. Univariate analysis showed that recurrent laryngeal nerve invasion was related to tumor size, Hashimoto's thyroiditis and cervical lymph node metastasis( χ2=6.964,4.814,6.078, P<0.05). Multivariate regression analysis showed that tumor size and lymph node metastasis in cervical region were independent risk factors for recurrent laryngeal nerve invasion(β=1.020,1.622, P<0.05). Hashimoto's thyroiditis was a protective factor for recurrent laryngeal nerve invasion (β=-1.881, P<0.05). Conclusions:When papillary thyroid carcinoma invaded the capsule, the risk of recurrent laryngeal nerve invasion was higher with larger tumor size and cervical lymph node metastasis, while Hashimoto's thyroiditis was a protective factor for the risk of recurrent nerve invasion.

Ras-related C3 botulinum toxin substrate 1 (Rac1), a member of the Rho GTPase family which plays important roles in dendritic spine morphology and plasticity, is a key regulator of cytoskeletal reorganization in dendrites and spines. Here, we investigated whether and how Rac1 modulates synaptic transmission in mouse retinal ganglion cells (RGCs) using selective conditional knockout of Rac1 (Rac1-cKO). Rac1-cKO significantly reduced the frequency of AMPA receptor-mediated miniature excitatory postsynaptic currents, while glycine/GABA receptor-mediated miniature inhibitory postsynaptic currents were not affected. Although the total GluA1 protein level was increased in Rac1-cKO mice, its expression in the membrane component was unchanged. Rac1-cKO did not affect spine-like branch density in single dendrites, but significantly reduced the dendritic complexity, which resulted in a decrease in the total number of dendritic spine-like branches. These results suggest that Rac1 selectively affects excitatory synaptic transmission in RGCs by modulating dendritic complexity.
