Objective:To evaluate the effects of endovascular embolization and microsurgical clipping on cognitive function in patients with intracranial aneurysm.Methods:A total of 80 patients with intracranial aneurysms,who were treated in Chongqing Hospital of Traditional Chinese Medicine from March 2014 to September 2015,were selected and randomly divided into control group(n=40) and experimental group (n=40).The control group was treated with microsurgical clipping,and the experimental group,with endovascular embolization.The postoperative cognitive function was assessed by the mini mental state examination scale (MMSE),and length of stay,in-hospital mortality rate,mortality rate in 1 year and the incidence of postoperative adverse reactions were compared between the two groups.Results:The total score (26.78± 0.85) of MMSE in the experimental group was higher than that (22.25± 0.63) of the control group (P＜0.05).The cognitive dysfunction rate (37.50％) of the experimental group was lower than that (55.00％) of the control group (P＜0.05).The length of stay [(6.7± 3.9) days] of the experimental group was lower than that [(9.6± 4.5) days] of the control group(P＜0.05).There were no significant differences in in-hospital mortality rate and mortality rate in 1 year,and the incidence of adverse reactions between the two groups (P＞0.05).Conclusion:Endovascular interventional therapy can improve the cognitive function of the patients with intracranial aneurysms and shorten the length of hospital stay.

Cerebral apoplexy is one of the main causes of death in the middle-aged and elderly population,which has higher mortality and disability rate.The incidence of the disease is increasing year by year and it is a serious threat to human life and health.Therefore,it is of great significance to find an effective target for the diagnosis and treatment of stroke.Thioredoxin (Trx) is the major thiol reducing agent in the cells,it is involved in many signal transduction pathways in the cells by regulating the redox state of the cell.It has disulphide reductase activity,which can reduce the oxidative stress injury in the rats after the stroke.Thioredoxin interacting protein (TXNIP) is an endogenous inhibitor of Trx,it can destroy the redox balance and promote the oxidative stress by binding/inhibiting the activity of Trx,while the inhibition or knockdown of TXNIP has obvious neuroprotective effects.Recent studies suggest that Trx/TXNIP may be involved in the pathophysiology of cerebral apoplexy by a variety of pathways.This article analyses the research status of Trx/TXNIP and studies the localization of Trx system in the central nervous system and the progress of Trx system in ischemic cerebral apoplexy.It reviews the mechanism of Trx/TXNIP in cerebral apoplexy and prospectes the signaling pathways involved in the pathophysiological process of Trx/TXNIP to provide new ideas for the treatment of cerebral apoplexy.

Objective:To investigate the effect of flt-3 ligand on the preparation of the fusional vaccine with dendritic cells and colorectal cancer cells,and the anti-tumor immunological reaction of the vaccine. Methods: ①In the presence of Flt-3 ligand、GM-CSF、IL-4 and TNF,the maturation of dendritic cells was made from peripheral blood;The preparation of the fusional vaccine was made in the presence of PEG. ②The biological characteristics of fusion cells,including their morphological specialties, the expression of cell surface phenotypes, their growth curves, inducing specific cytotoxic T lymphocyte(CTL), their possibility to proliferate into a new carcinoma in nude mice etc, were tested to verify their safety when used as anti-tumor immune reactions. Results: ①Flt-3 ligand can stimulate the full maturation of dendritic cells. Dendritic cells and Lovo cells could be fused by PEG. ②The fusion cells exhibited typical biological characteristics. They could not proliferate into new carcinomas in nude mice, and can inhibit the proliferation of Lovo cells efficiently. Conclusion: Flt-3 ligand can enhance the maturation of dendritic cell. The fused cells had poor proliferation abilities and could not proliferate into new carcinomas in immunodeficient animals. The fusion vaccine could induce specific cytotoxic T lymphocytes in vitro and was safe as a vaccine.

Objective To investigate the effect of glutamine (Gln) on the content of reduced glutathione hormone (GSH) and aminoglutaminic acid (Glu) of spinal cord following ischemia-reperfusion injury. Methods Totally 40 healthy adult male rabbits were randomly divided into five groups: sham-operation group (S group), ischemia-reperfusion injury group (I/R group), low-dose glutamine group (L Gln group), median-dose glutamine group (M Gln group) and high-dose glutamine group (H Gln group). After glutamine preconditioning, the model of spinal cord ischemia-reporfasion injury was established according to Zivin's method. The general status of animals was observed and the changes of Jacobs scoring were recorded in each group. Malondialdehydes (MDA), GSH, Glu and superoxide dismutase (SOD) activity in lumbar spinal cord tissues were determined using chemical colorimetry. The neuron number and deviation rate in spinal cord anterior horn were observed histopathologically. Results There was no significant difference between L Gin group and I/R group in behavior scoring, SOD activity, content of MDA and Glu, neuron number and deviation rate of spinal cord (P>0.05); however, there was a significant difference in GSH content of spinal cord (P<0.05). M Gln group and I/R group differed significantly (P<0.05) in behavior scoring, SOD activity, content of MDA, Glu, GSH, neuron number and deviation rate of spinal cord. Between H Gln group and M Gln group, there was no significant difference in behavior scoring, content of MDA and Glu, SOD activity, neuron number and aberration rate in spinal cord (P>0.05), whereas there was a significant difference in SOD activity and Giu content (P<0.05). Conclusion Pretreatment with medium-dose glutamine has a protective effect on spinal cord ischemia-reporfasion injury in rabbits, which may be related to the maintenance of GSH content, increase of SOD activity and reduction of MDA.

Objective:To investigate the effect of verapamil on the endotoxin-induced cytokine production and nuclear factor kappa B(NF-?B) activation in the liver. Methods:Fifty six adult male Sprague-Dawley rats were randomly divided into seven groups: group A: saline;group B:endotoxin(10 mg/kg,intraperitoneally,i.p.);group C,D,E,F:endotoxin(10 mg/kg) after treatment with verapamil(1,2.5,5,10 mg/kg i.p.respectively),and group G:verapamil alone(10 mg/kg).Tumor necrosis factor(TNF-?),interleukin-6(IL-6), interleukin-10(IL-10) and NF-?B in the liver tissues and the serum levels of ALT and AST were investigated at 1 h afer LPS injection. Results:Endotoxin stimulated production of TNF-?,IL-6 and IL-10,and activated NF?B in the liver.Verapamil attenuated acute liver injury,down-regulated endotoxin-induced pro-inflammatory cytokine production,up-regulated ant-inflammatory cytokines production and inhibited NF-?B activation in the liver in a dose-dependent manner.Conclusion:Verapamil can attenuate acute liver injury by down-regulating the production of TNF-?,IL-6 and up-regulating IL-10 in the liver in a dose-dependent manner,possibly via inhibition of NF-?B.

OBJECTIVETo determine the correlation between DNA load of human papillomavirus (HPV) and recurrence of condyloma acuminata (CA).

METHODSThe HPV6/11 and HPV16/18 DNA load of 31 cases of primary CA and 32 cases of recurrent CA were detected by real-time fluorogenic quantitative PCR.

RESULTSAmong the 63 CA patients, 62 cases were HPV6/11 DNA positive. The positive rate was 98.4%. The ranges of HPV6/11 DNA load in primary and recurrent CA were 1.4x10(3)-6.7x10(7) copies/ml and 1.2x10(4)-3.6x10(8) copies/ml respectively. Of 62 cases with HPV6/11 DNA positive, 7 cases were HPV16/18 DNA positive (11.3%). The ranges of HPV16/18 DNA load in primary and recurrent CA were 1.9x10(3)-1.6x10(4) copies/ml and 1.4x10(5)-1.7x10(7) copies/ml respectively. The HPV6/11 and HPV16/18 DNA load in recurrent CA were higher than in primary CA (P < 0.05). The DNA load of HPV6/11 was positively correlated with times of recurrence and course of disease (r=0.37 and 0.30 respectively).

CONCLUSIONCertain correlation exists between DNA load of HPV and recurrence of CA.

Patients undergoing maintenance dialysis show an increased susceptibility to tuberculosis because host immunity is decreased secondary to malnutrition, impaired cellular immunity, acidosis and etc. Extrapulmonary tuberculosis is more prevalent in patients with end stage renal disease than in normal subjects. Among the extrapulmonary tuberculosis in patients receiving hemodialysis, the diagnosis of tuberculous spondylitis is difficult because the symptoms are non specific and attributable to uremia, and the appearance of plain radiographs is often normal during the early phase of the disease. We experienced a case of tuberculous spondylitis in a hemodialysis patient. A 55 years old female admitted with fever, weight loss and back pain. Conventional radiograph of T-spine showed no definite abnormal finding. However, chest CT revealed heterogeneously enhancing soft tissue around the T8 vertebral body and T-spine MRI showed compatible finding to tuberculous spondylitis. She received radical excision of involved vertebra and confirmed tuberculous spondylitis with histologic finding from a surgical specimen. Following the administration of anti-tuberculosis medication(isoniazid, rifampin, pyraziamide, ethambutol) and radical excision, patient's symptom and sign were improved. The patient is maintaining dialysis with anti-tuberculosis medication for 5 months.
