Objective To study the effects of mild hypothermia on secondary cerebral vasospasm and levels of endothelin(ET),calcitonin gene-related peptide(CGRP)in CSF and plasma in patients with subarachnoid hemorrhage(SAH).Methods 56 patients with SAH were randomly divided into mild hypothermia group and control group.Based on the routine treating method,patients of mild hypothermia group were treated with local mild hypothermia.The levels of ET,CGRP in CSF and plasma were detected before and after treatment.And the incidence rates of secondary cerebral vasospasm cases were compared between the two groups.Results(1)At 7 d,14 d after treatment,ET levels in CSF and plasma in mild hypothermia group were significant lower than those in control group(P

BACKGROUND:Researches have found that minocycline plays a neuroprotective effect by inhibiting the microgliacel proliferation and activation and suppressing glial cels to release cytokines and chemokines. OBJECTIVE:To investigate the influence of minocycline on glial cel line derived neurotrophic factor, NTN and gene expression in substantia nigra and corpus striatum in Parkinson’s disease model rats.
METHODS:144 rats were randomly divided into four groups, with 36 rats in each group. In the normal control group, no intervention was given. In the model and experimental groups, 6-hydroxydopamine was injectedin the right substantia nigra pars compacta and ventral tegmental area to establish Parkinson’s disease models. In the sham surgery group, vitamin C was injected in the two points. In the experimental group, after model establishment, rats were intragastricaly given 4.5 g/L minocycline 45 mg/kg. From then on, additional 22.5 mg/kg minocycline was added every 12 hours. The last group was normal control group. Immediately, 12 hours, 1, 7, 14 and 21 days after model induction, SP immunohistochemistry was used to detect the expression of glial cel line derived neurotrophic factor and NTN expression in the substantia nigra and corpus striatum. RT-PCR was used to identify glial cel line derived neurotrophic factor and NTN mRNA expression in the substantia nigra and corpus striatum.
RESULTS AND CONCLUSION:Both in the substantia nigra and corpus striatum, the positive cel number and relative gene expression of glial cel line derived neurotrophic factor and NTN were lower in the model group than in the normalcontrol and sham surgery groups (P< 0.05). Glial cel line derived neurotrophic factor-and NTN-positive cel number and relative expression were higher in the experimental group than in the model group (P< 0.05). These findings suggest that minocyclinecan delay the process of Parkinson’s disease pathogenesis by promoting glial cel line derived neurotrophic factor protein and gene expression.

BACKGROUNDHemoptysis is a significant clinical entity with high morbidity and potential mortality. Both medical management (in terms of resuscitation and bronchoscopic interventions) and surgery have severe limitations in these patients population. Bronchial artery embolization (BAE) represents the first-line treatment for hemoptysis. This article discusses clinical analysis, embolization approach, outcomes and complications of BAE for the treatment of hemoptysis.

METHODSA retrospective analysis of 344 cases, who underwent bronchial arteriography at Tianjin Haihe Hospital between 2006 and 2013. Several aspects of outcome were analyzed: Demographics, clinical presentation, radiographic studies, results, complications and follow-up of BAE.

RESULTSThree hundred and forty-four consecutive patients underwent bronchial arteriography, 336 of 344 patients (97.7%) performed BAE; there were 1530 coils for 920 arteries embolized; the main responsible sources for bleeding were right bronchial artery (29.7%), left bronchial artery (21.6%), combined right and left bronchial trunk (18.4%), right intercostal arteries (13.3%); 61 patients (17.7%) had recurrent hemoptysis within 1 month after undergoing BAE, 74 patients (21.5%) had recurrent hemoptysis over 1 month after undergoing BAE; The common complications of BAE included subintimal dissection, arterial perforation by a guide wire, fever, chest pain, dyspnea, etc. The follow-up was completed in 248 patients, 28 patients had been dead, 21 patients still bleed, 92 patients had lost to follow-up.

CONCLUSIONSThe technique of BAE is a relatively safe and effective method for controlling hemoptysis . The complications of BAE are rare. Although the long-term outcome in some patients is not good, BAE may be the only life-saving treatment option in patients who are poor surgical candidates.

BACKGROUND:Classical drug for Parkinson’s disease is levodopa, but long-term application of levodopa can induce complications such as dyskinesias.
OBJECTIVE:To observe the effects of levodopa on learning and memory capacities of Parkinson’s disease rats and to study its mechanisms.
METHODS:The rat models of Parkinson’s disease were established using 6-hydroxydopamine. The 228 model rats were randomly divided into control group and experimental group. Rats in the experimental group were intraperitoneal y injected with 10, 20 and 30 mg/(kg?d) levodopa for 28 consecutive days. At 1, 3, 5, 7, 14 and 28 days after intraperitoneal injection, we observed the rats’ learning and memory capacities and tested plasma concentration of homocysteine and folic acid. Acetylcholinesterase activities in the rat hippocampus were measured. Hippocampal neurofibril ary tangles were observed using Bielschowsky staining.
RESULTS AND CONCLUSION:Increased dose of levodopa and prolonged application time obviously decreased learning and memory capacities in rats (P<0.001), increased plasma homocysteine levels, reduced folic acid levels (P<0.001), diminished acetylcholine esterase activities in the rat hippocampus (P<0.001), and increased neurofibril ary tangles in the rat hippocampus (P=0.000). Results suggested that a large dose of levodopa could significantly decrease the learning and memory capacities, and disease acetylcholine esterase activities, and increase neurofibril ary tangles in hippocampus. Its mechanism possibly associated with the increased plasma concentration of homocysteine.
