ABSTRACT
Two children with late-onset congenital central hypoventilation syndrome were reported, one of whom was male and had no abnormal manifestations after birth, respiratory failure occurs at the age of 1 year and 6 months. After being hospitalized, he was treated with oxygen inhalation and non-invasive ventilation, but carbon dioxide retention could not be corrected. After one month of tracheal intubation, he was failure to wean from ventilator, so tracheostomy was performed. He needs a ventilator to help breath while sleeping, and can breath autonomously during the day without ventilator. The other case was a female, with no abnormalities after birth. At the age of 11 months, she developed respiratory failure. During sleep, the child needs non-invasive assisted ventilation through a nasal mask, and during the day, she breathed autonomously.Two patients were followed up forever 2 years and their growth and development were normal.

Objective:To investigate the protective effect of lipopolysaccharide (LPS) preconditioning on cerebral ischemia reperfusion in rats.Methods:One hundred and twenty adult male SD rats were randomly divided into sham operation group, model group, low-dose LPS group (0.05 mg/kg), medium-dose LPS group (0.15 mg/kg), and high-dose LPS group (0.45 mg/kg). LPS was injected intraperitoneally for preconditioning, once a day for 7 consecutive days. Twenty-four hours after the last injection, the left middle cerebral artery occlusion model was induced by suture-occluded method. The model was reperfused 1.5 h after ischemia. At 24 h after reperfusion, the neurological deficit was evaluated by neurobehavioral score. The volume of cerebral infarction was measured by triphenyltetrazolium chloride staining. The serum levels of proinflammatory cytokines interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay. The expression of Toll-like receptor 4 (TLR4), matrix metalloproteinase (MMP) -2 and MMP-9 in ischemic brain tissue was detected by Western blot analysis.Results:Compared with the sham operation group, blood-brain barrier permeability was increased in the model group, serum IL-1β, IL-6 and TNF-α were up-regulated, and the expression of TLR4, MMP-2 and MMP-9 proteins in ischemic brain tissue was up-regulated. Compared with the model group, the neurological impairment of each LPS intervention group was significantly reduced, the volume of cerebral infarction was significantly reduced, the permeability of blood-brain barrier was significantly reduced, the serum IL-1β, IL-6 and TNF-α were down-regulated, and the expression of TLR4, MMP-2 and MMP-9 protein in ischemic brain tissue was down-regulated, especially in the medium-dose group and the high-dose group.Conclusions:LPS preconditioning can induce the formation of ischemic tolerance, inhibit the activation of TLR4-MMP-2/MMP-9 signal pathway, reduce the damage and inflammation of blood-brain barrier structure, and thus play a neuroprotective role in rats with cerebral ischemia reperfusion.
ABSTRACT
Objective To observe the curative effect of cervicogenic headache(CEH)treatment through the combination of pulse radio frequency(PRF)on the C2 dorsal rootganglion and continuous epidural space block.Methods Sixty patients with CEH in our hospital were randomly divided into groups A and B,30 cases in each group.The group A was treated with combination of PRF on cervical dorsal root ganglion and continuous epidural space block.The group B was treated with PRF on cervical dorsal root ganglion method.The pain VAS scores before treatment and at 1 week,3,6 months after treatment were compared between the two groups.Results Compared with pretreatment,the VSA scores at 1 week,3,6 wonths after treatment in the two groups had statistical difference(P＜0.05),moreover,the VAS score decrease in the group A was better than the group B.All the patients had no nerve and artery injury or infection complications.Conclusion It is safe and effective to treat cervical CEH through the combination of ganglion PRF on the cervical 2 dorsal root and continuous epidural space block.
ABSTRACT
Early exercise training after stroke is a therapeutic strategy that has been paid w idespread attention. A series of studies found that early exercise training after stroke can increase expression of neurotrophic factors and maintain the integrity of the blood-brain barrier by inhibiting acute neuroinflammation and apoptosis, and reduce brain damage. This artice reviews the neuroprotective roles of early exercise training after stroke and their possible molecular mechanisms.
ABSTRACT
PURPOSE: This phase I trial evaluated the question of whether the standard starting dose of axitinib could be administered in combination with therapeutic doses of cisplatin/capecitabine in patients with previously untreated advanced gastric cancer, and assessed overall safety, pharmacokinetics, and preliminary antitumor activity of this combination. MATERIALS AND METHODS: Patients in dose level (DL) 1 received axitinib 5 mg twice a day (days 1 to 21) with cisplatin 80 mg/m2 (day 1) and capecitabine 1,000 mg/m2 twice a day (days 1 to 14) in 21-day cycles. Maximum tolerated dose (MTD) was the highest dose at which 5 consecutive days of missed axitinib due to thrombocytopenia. DL1 was established as the MTD, since higher DL cohorts were not planned. Common grade 3/4 non-hematologic adverse events in 22 patients treated at DL1 included hypertension (36.4%) and decreased appetite and stomatitis (18.2% each). Cisplatin/capecitabine slightly increased axitinib exposure; axitinib decreased capecitabine and 5-fluorouracil exposure. Eight patients (36.4%) each had partial response or stable disease. Median response duration was 9.1 months; median progression-free survival was 3.8 months. CONCLUSION: In patients with advanced gastric cancer, standard doses of axitinib plus therapeutic doses of cisplatin and capecitabine could be administered in combination. Adverse events were manageable.

Radiofrequency thermocoagulation (RFT) of the gasserian ganglion is a routine and effective technique for the treatment of classical trigeminal neuralgia (CTN). In this study we compared its efficacy in patients with CTN and atypically symptomatic or mixed trigeminal neuralgia (MTN). Fifty-seven patients were treated with RFT for trigeminal neuralgia from June 2006 to February 2009. Thirty patients had CTN, and 27 had MTN. Outcomes were measured by using the visual analog pain scale (VAS) and patients' reports of quality of life (QOL), medication usage, and complications over a follow-up period of up to 3 years. Our results showed that the patients with MTN were younger, tended to have bilaterial involvement of the first division, and were unresponsive to treatment. All surgeries were completed smoothly. About 86.7% CTN patients and 48.1% MTN patients responded immediately to RFT. The VAS scores were significantly higher in the CTN group than in MTN group (P<0.05). Kaplan-Meier curves showed that 1-year, 2-year, and 3-year pain relief rates were 76.7%, 73.3%, and 73.3% in the CTN group and 46.6%, 41.4%, and 41.4% in the MTN group, respectively. The rates of pain relief for both groups leveled off at 2 years. Complications included numbness, dysesthesia, and anesthesia dolorosa. RFT did not cause any deaths and complications were low. The treatment was very effective for CTN and, to some degrees, effective for MTN. If numbness, dysesthesia, and anesthesia dolorosa are limited to the trigger area, QOL will be greatly improved.
