[Stakeholder Analysis of the Application of Artificial Intelligence in the Field of Primary Health Care].

The application of artificial intelligence in the field of primary health care can effectively improve diagnosis and treatment,avoid over-examination and over-medication,and make up for the shortage of high-quality medical resources in primary medical and health institutions.Focusing on the application of artificial intelligence in the field of primary health care,this paper analyzes the existing application modes and typical cases,studies its main stakeholders,interest demands and problems,and provides corresponding suggestions.

Crystal structure of aqua-bis-[4-(methyl-sulfan-yl)benzoato-κO](1,10-phenanthroline-κ(2) N,N')copper(II) monohydrate.

In the title compound, [Cu(C8H7O2S)2(C12H8N2)(H2O)]·H2O, the central Cu(II) atom is five-coordinated in a slightly distorted square-pyramidal environment by two N atoms from a 1,10-phenanthroline ligand, one O atom from the carboxylate group of one 4-(methyl-sulfan-yl)benzoate anion and one water O atom in the equatorial plane while the apical position is occupied by the O atom of a carboxylate group of the second anion. In the crystal, a three-dimensional supra-molecular network is formed through weak inter-molecular C-H⋯O and C-H⋯S inter-actions and π-stacking between the 1,10-phenanthroline ligand and the aromatic rings of symmetry-related 4-(methyl-sulfan-yl)benzoate ligands.

[Correlations between serum hypoxia inducible factor-1α, vascular endothelial growth factor and computed tomography perfusion imaging at pre-and post-TACE in patients with primary hepatic carcinoma].

Objective: To explore the correlations between the serum levels of hypoxia inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF) and computed tomography (CT) perfusion parameters at pre- and post-transcatheter arterial chemoembolization (TACE) in patients with primary hepatic carcinoma (PHC).

Methods: A total of 22 PHC patients were recruited.Their serum levels of HIF-1α and VEGF were measured and CT perfusion imaging (CTPI) was performed at Day 1 pre- and Days 32-40 post-TACE to compare and analyze the relevance of the changes of serum levels of HIF-1α, VEGF, tumor's hepatic artery perfusion (HAP), portal vein perfusion (PVP) and hepatic artery perfusion index (HPI) at pre- and post-TACE.

[Fabrication of two dimensional silver cavity array and its application in SERS detection].

The highly ordered two dimensional micro-/nano-sized silver cavity was fabricated by galvanostatic multistep method using ordered arrays of close-packed 700 nm diameter polystyrene spheres as templates. The morphology and the surface plasmon resonance of this silver cavity array were characterized by scanning electron microscope and reflectance UV-Vis spectra, and surface-enhanced Raman scattering (SERS) spectra of p-aminothiophenol (PATP) and Rhodamine 6G (R6G) on as-prepared substrate were also studied. The results show that: the depth of cavities can be easily regulated through varying the parameters of the electrochemical deposition.

Correlation of atherosclerotic renal artery stenosis with extracranial carotid and intracranial cerebral artery atherosclerosis in patients with ischemic stroke.

Objective: This study was to evaluate the relationship of atherosclerotic renal artery stenosis (ARAS) with extracranial carotid arteries atherosclerosis (ECAS) and intracranial cerebral atherosclerosis (ICAS) in ischemic stroke (IS) patients.

Methods: This study was a prospective cohort analysis of consecutive patients with IS who had not a history of renal artery stenosis (RAS). Abdominal aortography was performed to screen for RAS after the cerebrovascular diagnostic procedure.

Cerebral lipiodol embolism after transarterial chemoembolization for hepatic carcinoma: a case report.

We report a case of cerebral lipiodol embolism (CLE) after transarterial chemoembolization (TACE) for unresectable hepatic carcinoma (HCC). A 54-year-old man with unresectable HCC underwent TACE via the right hepatic artery and right inferior phrenic artery using a mixture of 40 mg pirarubicin and 30 mL lipiodol. His level of consciousness deteriorated after TACE, and non-contrast computed tomography revealed a CLE.

Serum HIF-1alpha and VEGF levels pre- and post-TACE in patients with primary liver cancer.

Objective: To investigate the expression levels of serum hypoxia inducible factor 1 alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF) pre- and post-transcatheter arterial chemoembolization (TACE) in patients with primary liver cancer (PLC), and correlations between prognosis factors and serum HIF-1alpha as well asVEGF levels.

Methods: Forty consecutive patients fulfilling diagnostic criteria for PLC undergoing TACE from March 2008 to May 2009 were enrolled into the study. The serum HIF-1alpha and VEGF levels of PLC patients pre- and 1 day, 1 week, 1 month post-TACE were analyzed using ELISA, and compared with that of 20 healthy volunteers.

Penta-carbonyl-1κC,2κC-(4-iodo-phenyl isocyanide-1κC)(μ-propane-1,3-dithiol-ato-1:2κS,S':S,S')iron(I)(Fe-Fe).

In the title compound, [Fe(2)(C(7)H(4)IN)(C(3)H(6)S(2))(CO)(5)], the Fe-Fe distance of 2.5156 (11) Å compares well with that in related model structures. The phenyl isocyanide ligand is in the basal position and trans to the S atoms of the propane-dithiol-ate ligand due to steric hindrance.

[Blood supply of pulmonary metastases and its clinical significance].

Background & Objective: Interventional treatment has been widely applied to primary lung carcinoma, but seldom applied to pulmonary metastases because the blood supply of pulmonary metastases has rarely been investigated, and the present understanding is controversial. This study was to explore the correlation of the clinical value of bronchial arterial chemotherapeutic infusion (BAI) combined bronchial arterial embolization (BAE) to the blood supply of pulmonary metastases.

Methods: Bronchial artery angiography was performed on 33 patients with pulmonary metastases to assess the blood supply and the distribution of pulmonary metastases.
