Observation on the clinical efficacy of external ventricular drain combined with intraventricular urokinase injection and intravenous piracetam in the treatment of intraventricular hemorrhage.

Objective: To observe the clinical efficacy of external ventricular drain combined with intraventricular urokinase injection and intravenous piracetam in the treatment of intraventricular hemorrhage. Methods: A randomized controlled trial was used in this study conducted at Baoding First Central Hospital, China from January 2017 to December 2019. Sixty patients with intraventricular hemorrhage were randomly divided into two groups. Patients in the control group were treated with external ventricular drain, while patients in the experimental group were given intraventricular urokinase injection and intravenous piracetam on the basis of the control group. The incidence of adverse drug reactions, hospitalization time, hematoma elimination time, and drainage tube removal time in two groups were compared and analyzed including the cerebrospinal fluid protein content, changes in GCS score, neurological function recovery (ADL score), and Glasgow outcome scale (GOS) of the two groups after treatment. Results: The hematoma elimination time, drainage tube removal time and hospitalization time of the experimental group were shorter than those of the control group, with a statistically significant difference (P<0.05). After treatment, compared with the control group, the protein content of cerebrospinal fluid in the experimental group decreased more significantly (P=0.00), the GCS score was higher (P=0.00), the overall good rate of neurological function was higher (P=0.04), while the rate of good prognosis was higher (P=0.03). Within one month of treatment, the incidence of surgical complications in experimental group was significantly lower than that in control group (P=0.04). Conclusions: External ventricular drain combined with intraventricular urokinase injection and intravenous piracetam is an effective method for the treatment of intraventricular hemorrhage, which is worthy of clinical promotion.

An observation of the clinical efficacy of combining Riluzole with mannitol and hyperbaric oxygen in treating acute spinal cord injury.

OBJECTIVE: To examine the clinical efficacy of combining Riluzole with mannitol and hyperbaric oxygen therapy in treating thoracolumbar vertebral fracture-induced acute spinal cord injury (ASCI). METHODS: From June 2015 to May 2018, 80 patients with thoracolumbar fractures and ASCI who were treated at Baoding First Central Hospital were selected. All patients underwent posterior laminectomy and screw fixation, and they were randomly divided into two groups using a random number table method. The control group received conventional postoperative treatment, while the experimental group was treated with riluzole combined with mannitol and hyperbaric oxygen on the basis of conventional treatment. The recovery of nerve function which included motor function and sensory function, and the changes of serum IL-6, CRP, BDNF, BFGF and other factors before treatment and four weeks after treatment of the two groups of patients were observed and evaluated. RESULTS: After treatment, the motor function scores and sensory function scores of the two groups of patients were improved compared with those before treatment (p<0.05). Compared with the control group, the experimental group improved significantly, and the difference was statistically significant (p<0.05). The levels of IL-6, BDNF and NFGF in the experimental group were significantly lower than those in the control group (p<0.05). CONCLUSIONS: For patients with thoracolumbar fractures and ASCI undergoing laminar decompression and fixation, the comprehensive treatment plan of riluzole combined with mannitol and hyperbaric oxygen has certain advantages. Compared with the conventional therapy, it may significantly improve the movement and sensory functions of patients, relieve the inflammatory response of spinal cord, and promote recovery from the injury.

Neuroprotective potential of fisetin in an experimental model of spinal cord injury: via modulation of NF-κB/IκBα pathway.

AIM: To evaluate neuroprotective efficacy of fisetin against the experimental model of spinal cord injury (SCI). MATERIALS AND METHODS: SCI was induced in male Sprague-Dawley rats by placing an aneurysm clip extradurally. Rats were treated either with vehicle or fisetin for 28 days after SCI. RESULTS: Treatment with fisetin significantly attenuated SCI-induced alternations in mechano-tactile and thermal allodynia, hyperalgesia and nerve conduction velocities. SCI-induced upregulated tumor necrosis factor-alpha, interleukins, inducible nitric oxide synthase, cyclooxygenase-II, Bcl-2-associated X protein and caspase-3 mRNA expressions in the spinal cord and these were markedly reduced by fisetin. Spinal nuclear factor kappa B and nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha protein levels were also significantly downregulated by fisetin. Hematoxylin and eosin staining of spinal cord suggested that fisetin significantly ameliorated histological aberrations such as neuronal degeneration, necrosis and inflammatory infiltration induced in it. CONCLUSION: Fisetin exerts neuroprotection via modulation of nuclear factor kappa B/nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha pathway by inhibiting release of inflammatory mediators (inducible nitric oxide synthase and cyclooxygenase-II), proinflammatory cytokines (tumor necrosis factor-alpha and interleukins), apoptotic mediators (Bcl-2-associated X protein and caspase-3).
