A Stable 3-4 Heterometallic Cluster with Magneto-Optical Activity.

A stable 3-4 heterometallic cluster, namely, {DyNiL(NO)(CO)(CHOH)}·CHCN (DyNi, HL = 8-hydroxyquinoline), has been solvothermally synthesized and structurally characterized. The compound exhibits an interesting structure in which a tetrahedron based on 4 ions interpenetrates with a square pyramid based on 3 ions. Besides, a unique intermolecular interaction was found in DyNi, giving rise to its high stability not only when it is in the solid state but also when it dissolves in organic solvents.

Severe thoracic trauma caused left pneumonectomy complicated by right traumatic wet lung, reversed by extracorporeal membrane oxygenation support-a case report.

Background: Double lumen intubation and one-lung ventilation should be applied without delay in cases of traumatic main bronchial rupture. In most cases, when the patients' vital signs have been stabilized, the repair can be performed. However, when one-lung ventilation is complicated by traumatic wet lung, the mortality rate is likely to be much higher.

[Human leucocyte antigen-DR expression on CD(14)(+) monocytes and its relationships with multiple organ dysfunction syndrome in severe sepsis].

Objective: To explore the changes of CD(14)(+) monocyte human leucocyte antigen DR (HLA-DR) and their relationship with multiple organ dysfunction syndrome (MODS) in severe sepsis.

Methods: Ninety-one patients with a definite diagnosis of severe sepsis in the intensive care unit (ICU) were included. CD(14)(+) monocyte HLA-DR levels were detected by flow cytometry on the first, 4th and 7th days of the study, and Marshall scores and prognosis on day 28 were evaluated.

[Effect of continuous blood purification and thymosin alpha1 on the cellular immunity in patients with severe sepsis: a prospective, randomized, controlled clinical trial].

Objective: To discuss the effect of continuous blood purification (CBP), thymosin alpha1 and combined therapy on cellular immunity in patients with severe sepsis.

Methods: Ninety-one patients, age over 18 years, suffering from severe sepsis with Marshall score over 5, admitted to the intensive care unit (ICU) from June, 2004 to October, 2007, were randomly divided into four groups. The patients in control group (24 cases) were treated with classical Surviving Sepsis Campaign (SSC) therapy, those in CBP group (22 cases) were treated with continuous renal replacement therapy (CRRT) or molecular adsorbent recirculating system (MARS) in the first 3 days.

[Emergency bedside temporary cardiac pacing through the left subclavicular vein guided by pacemaker impulse].

Objective: To investigate the feasibility and merits of emergency bedside temporary cardiac pacing through left subclavicular vein guided by pacemaker impulse.

Methods: The left subclavicular vein was punctured with Seldinger technique for insertion of a cannula. After setting the rate of pacemaker at 20 beat/min above the patients' spontaneous heart rate with output current of 5 mA and sensing voltage of 3 mV, the electrode was inserted through the cannula until the electrocardiograph displaying pulsed signal and pacing rhythm.

[Intensive care and treatment of severe ovarian hyperstimulation syndrome].

Objective: To investigate the clinical manifestations, pathogenesis and treatment of severe ovarian hyperstimulation syndrome (OHSS).

Methods: The clinical data of 20 OHSS patients were analyzed retrospectively.

Results: Severe OHSS occurred after controlled ovarian hyperstimulation for superovulation.

[The first case of severe acute respiratory syndrome in Foshan].

Objective: To evaluate the epidemiologic feature, diagnosis and treatment of severe acute respiratory syndrome (SARS).

Methods: To describe the epidemiologic and clinical features of the first case of SARS in Foshan city, Guangdong province retrospectively, and to review the diagnostic procedure.

Results: This case had the following features: (1) a history of contact with mild cats and eating the animal's meat; (2) high fever (temperature, > 38 degrees C), followed by dry cough, rapid progression to respiratory failure, followed by radiographic evidence of bilateral air-space lesions; (3) no leukocytosis; (4) spread to 4 family members who had had direct contact with this patient; (5) the patient's serum SARS virus IgG was confirmed to be positive; (6) the patient was treated with anti-viral agents, antibiotics and mechanical ventilation and molecular adsorbent re-circulating system (MARS).
