Therapy of Severe Heatshock in Combination With Multiple Organ Dysfunction With Continuous Renal Replacement Therapy: A Clinical Study.

This study aimed to compare the clinical effects of continuous renal replacement therapy (CRRT) and routine therapy in heatshock (HS) patients.We retrospectively reviewed the clinical information of 33 severe exertional HS patients who were treated from February 1998 to October 2013. On the basis of whether or not CRRT therapy was used in addition to conventional therapy, patients were divided into a CRRT group (n = 15) and a control group (n = 18).

Clearance of serum solutes by hemofiltration in dogs with severe heat stroke.

Background: We have previously reported that hemofiltration (HF) may be an effective additional means of treating heat stroke when rapid cooling is not effective.

Methods: Dogs were assigned to a heat stroke (control) or heat stroke + hemofiltration (HF) group (n = 8 each group). After heat stroke induction, dogs in the HF group received HF for 3 h.

Early plasma exchange for treating ricin toxicity in children after castor bean ingestion.

Plasma exchange (PE) for the treatment of ricin toxicity has not been previously reported. Here we describe the use of PE to treat children who experienced ricin toxicity after ingesting castor beans. Seven children (median age: 8.

[Mutational analysis of MYO1E in Chinese children with familial steroid-resistant nephrotic syndrome].

Objective: Steroid-resistant nephrotic syndrome (SRNS) with MYO1E mutations has been identified as autosomal recessive focal segmental glomerulosclerosis (FSGS). To date, only two homozygous mutations in the MYO1E gene were reported in three families with FSGS. This study aimed to examine mutations in the MYO1E gene in children with familial SRNS in the Han Chinese ethnic group.

The effects of genistein on transforming growth factor-β1-induced invasion and metastasis in human pancreatic cancer cell line Panc-1 in vitro.

Background: Pancreatic cancer is a devastating disease with the worst mortality rate. Therefore, a rational strategy for future drug development is critical. Genistein is a small, biologically active flavonoid that is found in high amounts in soy.

Permeation of dimethyl sulfoxide into articular cartilage at subzero temperatures.

Osteochondral allografting has been proved to be a useful method to treat diseased or damaged areas of joint surfaces. Operational long-term stocks of grafts which supply a buffer between procurement and utilization would contribute to the commercialization or industrialization of this technology. Vitrification has been thought to be a promising method for successful preservation of articular cartilage (AC), but high concentration cryoprotectants (CPAs) are used which may cause high cellular toxicity.

Effects of continuous haemofiltration on serum enzyme concentrations, endotoxemia, homeostasis and survival in dogs with severe heat stroke.

Aim: To examine the effectiveness of continuous haemofiltration as a treatment for severe heat stroke in dogs.

Methods: Dogs were randomly allocated to a control or continuous haemofiltration group (both n=8). Heat stroke was induced by placing anaesthetised dogs in a high temperature cabin simulator.

Moisture sorption characteristics of freeze-dried human platelets.

Freeze-drying is a promising method for a long-term storage of human platelets. The moisture sorption characteristics of freeze-dried human platelets (FDHPs) were studied in this paper. The moisture sorption isotherms of FDHPs and freeze-dried lyophilization buffer (FDLB) were measured at 4, 25, and 37 °C.

Preliminary study on the freeze-drying of human bone marrow-derived mesenchymal stem cells.

Long-term preservation and easy transportation of human bone marrow-derived mesenchymal stem cells (hBM-MSCs) will facilitate their application in medical treatment and bioengineering. A pilot study on the freeze-drying of hBM-MSCs was carried out. hBM-MSCs were loaded with trehalose.

An experimental study of the use of ultrasound to facilitate the loading of trehalose into platelets.

Trehalose is widely used as a freeze-drying protectant in biomaterial preservation. For this purpose, trehalose has to be loaded into the cells but this is difficult and many methods have been tried. The application of ultrasound can temporarily permeabilize cell membranes, which offers a non-chemical, non-viral, and non-invasive method of cellular drug delivery.

[Preparation of a novel telomerase inhibitory protein LPTS-L].

The gene for LPTS is originally cloned as a human liver-related putative tumor suppressor (LPTS) gene that encodes a full length protein of 328 amino acids (LPTS-L). LPTS-L is also identified as a telomerase inhibitor to regulate telomere length in the cells. To facilitate the functional and structural studies of LPTS-L protein, the cDNA for LPTS-L was cloned into the expression vector pET-24 in frame to generate a recombinant plasmid pET-24-LPTS.

Freeze-drying of human platelets: influence of saccharide, freezing rate and cell concentration.

Freeze-drying of human platelets is one potentially ideal approach for long-term preservation of platelets. In this study, effects of concentration and type of saccharides, freezing rate and initial cell concentration on the recovery of freeze-dried platelets were investigated. Annexin V binding platelet activation assays, scanning electron microscopy and platelet aggregation upon thrombin (1 U/ml) addition were used to evaluate the effectiveness of platelet freeze-drying.

Non-cytolytic antigen clearance in DNA-vaccinated mice with electroporation.

Aim: To explore the potential of electroporation (EP)-mediated hepatitis B virus (HBV) DNA vaccination for the treatment of chronic HBV infection.

Methods: BALB/c mice were vaccinated with HBV DNA vaccine encoding for the HBV preS(2)-S antigen, combined with or without EP. HBV surface antigen expression plasmid was administered into mice liver via a hydrodynamic injection to mimic HBV infection.

Freeze-drying of human platelets: influence of intracellular trehalose and extracellular protectants.

Freeze-drying is an ideal alternative for long-term preservation of platelets in blood banks. Intracellular trehalose is believed to be an effective lyoprotectant for preserving cells during freeze-drying. In this study, 13 mM intracellular trehalose was loaded into human platelets through fluid-phase endocytosis pathway.

[Treatment of hemolytic uremic syndrome after acute stage].

Objective: Hemolytic uremic syndrome (HUS) is a common primary disease that can cause acute renal failure in childhood. Renal disease is the most important long-term complication in patients who survived the acute stage of HUS. Use of angiotensin-converting enzyme inhibitors (ACEI) and a restricted protein intake may be beneficial to the patients.

Chiral Synthesis via Organoboranes. 46. An Efficient Preparation of Chiral Pyridino- and Thiopheno-18-crown-6 Ligands from Enantiomerically Pure C(2)-Symmetric Pyridine- and Thiophenediols(1).

Asymmetric reduction of 2,6-diacylpyridines with B-chlorodiisopinocampheylborane provides the corresponding C(2)-symmetric diols in very high de and ee. Asymmetric allylboration of 2,6-pyridinedicarboxaldehyde and 2,5-thiophenedicarboxaldehyde provides the corresponding bis-homoallylic alcohols in very high de and ee. These optically pure diols were converted to the disodium or dipotassium salts and treated with tetra(ethylene glycol) ditosylate to obtain the corresponding chiral pyridino and thiopheno-18-crown-6 ligands.
