ObjectiveTo evaluate the clinical benefits of early right median nerve electrical stimulation on coma patients following craniocerebral trauma. MethodsCraniocerebral trauma patients with up to two weeks of coma in the years 2005-2011 were involved in the study and were randomly divided into control group (received routine management ) and treatment group (routine management plus right median nerve electrical stimulation).The treatment lasted for a period of more than two weeks.The clinical efficacy of the right median nerve electric stimulation and the conscious status of the patients within six months after craniocerebral trauma were observed.ResultsA total of 456 patients were enrolled in the study,of whom 437 patients completed the treatment course,including 221 patients in the treatment group and 216 in the control group.There was no complication related to electric stimulation during the treatment.Cerebral blood flow (CBF) imaging and brain stem evoked potential (BEP) examination demonstrated significant improvement in the treatment group.A total of 386 patients were followed up for six months postoperatively,which showed that there were 122 patients with regained consciousness,46 in minimally conscious state and 36 in vegetative state in the treatment group (204 patients) and there were 84 patients with regained consciousness,40 in minimally conscious state and 58 in vegetative state in the control group ( 182 patients).The patients in the treatment group showed a higher ratio of regained consciousness and a lower ratio of vegetative state compared with the control group,but the ratio of minimally conscious state showed no statistical difference between two groups. ConclusionsRight median nerve electrical stimulation is a suitable coma awaking means at early stage after craniocerebral trauma.

Objective To investigate the efficacy of endovascular stenting for aortic arch artery stenosis after nasopharyngeal carcinoma radiotherapy. Methods The clinical data of 8 patients with symptomatic severe aortic arch artery stenosis after nasopharyngeal carcinoma radiotherapy were analyzed retrospectively. The patients were all received endovascular stenting,and their improvement of cerebral ischemic symptoms was observed. They were followed up by cervical color Doppler ultrasound.Results The whole brain vascular DSA confirmed that there were 24 severe arterial stenoses on the aortic arch arteries of extracranial segments in 8 patients,including 11 in internal carotid artery,2 in common carotid artery,10 in vertebral artery and 1 in subclavian artery. The patients were treated with vascular angioplasty and stenting respectively. All the patients were followed up for 1 year;there were no recurrence of cerebral ischemic symptoms.Cervical color Doppler ultrasound did not reveal any obvious restenosis. Conclusion Endovascular stent angioplasty for the treatment of aortic arch artery stenosis after nasopharyngeal carcinoma radiotherapy is relatively safe and feasible.

Objective To investigate the effect of SABP, a water-soluble component of Salvia miltiorrhiza, on the growth of orthotopic transplantation of H22 liver cancer and the immune microenvironment of liver cancer. Methods We established a mouse model of orthotopic transplantation of H22 cell liver cancer in BALB/c mice. ELISA was used to detect the expression of PD-L1, TGF-β, IL-1β, IL-10, IL-4, IFN-γ, IL-18, IL-7, IL-2, CCL-2 and CCL-21 in the liver. We counted the organ indexes of liver, spleen and kidney. Results SABP inhibited the growth of orthotopic transplantation tumors of H22 cell liver cancer, and increased the expression levels of PD-L1, TGF-β, IL-1β and IL-10 in the microenvironment of liver cancer, as well as the liver, spleen and kidney coefficients. Conclusion SABP could inhibit the growth of orthotopic transplantation tumors of H22 cell liver cancer and promote the expression of PD-L1, TGF-β, IL-1β and IL-10 in the microenvironment of liver cancer.

Objective To explore the improvements of high-fat intake on lung injury induced by Paragonimus proliferus infection in rats, and to preliminarily explore the mechanisms underlying the role of cytochrome P450 4A1 (CYP 4A1) in the improve ments. Methods SD rats were randomly assigned into three groups, including the normal control group (n = 10), the infection and normal diet group (n = 12) and the infection and high-fat diet group (n = 12). Rats in the normal control group were fed with normal diet and without any other treatments, and animals in the infection and normal diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with normal diet, while rats in the infection and high-fat diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with high-fat diet. All rats were sacrificed 28 weeks post-infection, and serum samples and lung specimens were collected. Following hematoxylin-eosin (HE) staining of rat lung specimens, the rat lung injury was observed under an optical microscope, and alveolitis was evaluated using semi-quantitative scoring. Serum interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNF-α) levels were measured using enzyme-linked immunosorbent assay (ELISA), and the cytochrome P450 4A1 (CYP 4A1) expression was quantified in rat lung specimens at transcriptional and translational levels using quantitative real-time PCR (qPCR) and Western blotting assays. Results Alveolar wall thickening, edema and inflammatory cell infiltration were alleviated 28 weeks post-infection with P. proliferus in rats in the infection and high-fat diet group relative to the infection and normal diet group, and no alveolar consolidation was seen in the infection and high-fat diet group. The semi-quantitative score of alveolitis was significantly higher in the infection and normal diet group [(2.200 ± 0.289) points] than in the normal control group [(0.300 ± 0.083) points] and the infection and high-fat diet group [(1.300 ± 0.475) points] (both P values < 0.05), and higher serum IL-1β [(151.586 ± 20.492)] pg/mL and TNF-α levels [(180.207 ± 23.379) pg/mL] were detected in the infection and normal diet group than in the normal control group [IL-1β: (103.226 ± 3.366) pg/mL; TNF-α: (144.807 ± 1.348) pg/mL] and the infection and high-fat diet group [IL-1β: (110.131 ± 12.946) pg/mL; TNF-α: (131.764 ± 27.831) pg/mL] (all P values < 0.05). In addition, lower CYP 4A1 mRNA (3.00 ± 0.81) and protein expression (0.40 ± 0.02) was quantified in lung specimens in the infection and normal diet group than in the normal control group [(5.03 ± 2.05) and (0.84 ± 0.14)] and the infection and high-fat diet group [(11.19 ± 3.51) and (0.68 ± 0.18)] (all P values < 0.05). Conclusion High-fat intake may alleviate lung injuries caused by P. proliferus infection in rats through up-regulating CYP 4A1 expression in lung tissues at both translational and transcriptional levels.
