Objective To analyze the relationship between the level of serum homocysteine and cerebral artery stenosis in cerebral infarction patients.Methods Clinical data from 165 cerebral infarction patients who had been done cerebral angiography examination were analyzed.According to the level of serum homocysteine,the patients were divided into 5.0-15.0 μmol/L group,15.1-20.0 μmol/L group and above 20.1 μmol/L group.Other risk fac-tors including age,gender,blood pressure,blood lipid and blood glucose were recorded.The number of cerebral vascu-lar stenosis in different parts of brain were analyzed,and then make a decision of the relationship between the level of serum homocysteine and cerebral artery stenosis,as well as the other risk factors.Results Among 165 cases,74 cases (48.15%)came from 5.0-15.0 μmol/L group and the number of stenosal cerebral vascular was 36strips,50 cases (30.12%)came from 15.0-20.0 μmol/L group and the number of stenosal cerebral vascular was 66 strips,41 cases (24.70%)came from above 20.1 μmol/L group and the number of stenosal cerebral vascular was 67.Analysis of variance was conducted between the numbers of stenosal cerebral vascular of each group,the differences were significant (F =4.12,P <0.05).Conclusion In cerebral infarction patients,the incidence of Hcy(hyperhomocysteinemia) was higher than that of normal hcy.2.shows more serious damage of intracranial and extracranial arterial sclerosis occur in patients with the increase of homocysteine levels.

Objective:To study the effect of edaravone on EAE rats and the underlying mechanism.Methods:Wistar rats were immunized with GPSCH,and randomly divided into control group,EAE group,dexamethasone group,low dose of edaravone group and high dose of edaravone group.The morbidity of disease and clinical signs were observed.The pathological changes of spinal cord tissue sections were observed under light microscopy after HE staining and trichrome staining.The expression of Nrf2 and HO-1 was observed by immunohistochemistry.Results:Morbidity of high dose of edaravone group (8.33%) and DXM group (0%) was significantly lower than in EAE group (58.3%) (P

Objective:EAE model of male and female Wistar rats was established respectively.The sex difference was evaluated.Methods:40 wistar rats were devided into male and female group (n=20).EAE model was established respectively in the two groups using Guinea pig spinal cord homogenate without PBS perfusion.30 days later,the spinal cord were taken and embedded in wax,and paraffin sections of the two groups were examined by histopathology.The differences in onset time,incidence rate,course of disease and neurologic score between the two groups were evaluated.Results:The onset time of female group was 13.67?3.50 days,its incidence rate was 60%.The onset time of male Wistar rat was 12.18?1.55 days,and its incidence rate was 85%.The feature of diseases course in female rat was relapse after recovery,but that in male rat was transient.The average clinical score of female group was 2.20?1.96,and that of male group was 3.46?1.61.Conclusion:Compared with female Wistar rat,the male had higher incidence rate and its diseases course was transient.The results of our study provided a useful foundation for further studies on the pathogenesis and the sex differences of multiple sclerosis.

Objective To explore the related risk factors of renal function after partial nephrectomy,and provide the reference for clin-ic. Methods The data of 31 patients with small renal cancer in our hospital from January 2010 to June 2014 were analyzed. Before and after the treatment,the relationship of renal glomerular filtration rate ( GFR) with the change and clinical pathological factors were analyzed,the single factor analysis used t test,multiple factors analysis adopted multi-factor unconditioned logistic regression analysis. Results Single fac-tor analysis results showed that renal function after partial nephrectomy was closely related to the age,diabetes mellitus,blocking time,the size of the tumor,renal volume reduction ratio,the difference was statistically significant (P<0. 05). Many factors of logistic regression showed that it was closely related to the age,blocking time,renal volume reduction ratio(P<0. 05). Conclusion The age,blocking time,renal vol-ume reduction ratio are risk factors for renal function after partial nephrectomy.

Objective To establish the optimum syndrome classification method by using the technology of modern TCM diagnosis and artificial intelligence analysis method for menopausal syndrome differentiation of TCM. Methods Diagnostic information of menopausal syndrome patients was collected and syndromes were classified according to TCM syndrome differentiation standard. Three kinds of common data mining classification algorithm, Bayesian network, K-nearest neighbors and support vector machine, were used for analysis on information data of the four methods of diagnosis of menopausal syndrome.Results The time, classification accuracy, coverage rate and margin curve of establishing TCM syndrome model by the three kinds of algorithm methods under the circumstances of same training and data. The influence of the number of training samples of 3 kinds of algorithm methods was analyzed, and the model established by the three kinds of algorithms was evaluated.Conclusion Bayesian network algorithm is better than the other two methods in the menopausal syndrome classification effect.

Objective To explore the interaction between a serotonin transporter gene promoter region polymorphism(5-HTTPR) and stress in predicting anxiety symptoms.Methods Through random cluster sampling,a total of 252 healthy adolescents participated in this study.During the initial assessment,all participants completed the Adolescent Life Events Questionnaire (ALEQ) and Multidimensional Anxiety Scale for Children (MASC) to assess their levels of stress and anxiety and were genotyped for the 5-HTTLPR polymorphism.Participants subsequently completed MASC and ALEQ once every three months during the subsequent 24 months.A multilevel model was used to investigate the interaction between 5-HTTLPR and stress that predict anxiety symptoms.Results The results indicated no major effect of 5-HTTLPR in males (β=0.80,P＞0.05)or females(β=-0.21,P＞0.05).There were major effects of stress in males(β=0.30,P＜0.01) and females (β=0.33,P＜0.01)and a significant interaction between 5-HTTLPR and stress.Females with at least one 5-HTTLPR S allele(β=0.11,P＜ 0.01)and males with at least one 5-HTTLPR L allele(β=-0.10,P＜0.01)exhibited more anxiety symptoms under stressful situations.Conclusion The interaction between 5-HTTLPR and stress can predict anxiety symptoms in adolescents.There are gender differences on the 5-HTTLPR × stress interaction.

Objective To investigate the effects of the laparoscopic surgery and open surgery on the postoperative intestinal function recovery time in elderly patients with colorectal cancer(CRC).Methods 66 elderly patients with CRC and treated in the 2nd People's Hospital of Kunming from January 2021to July 2022 were chosen and divided into the control group(n = 33)and the study group(n = 33)according to different operation ways.And the postoperative bowel function recovery time,radical,complications and surgical index were compared between the two groups.Results The recovery time of intestinal function in the study group was significantly shorter than that in the control group(P<0.05),but there was no significant difference in radical indicators between the two groups(P>0.05).The incidence of complications in the study group was lower than that in the control group,and the difference was statistically significant(P<0.05).The operation time of the study group was longer than that of the control group and there was the statistically significant difference(P<0.05),while the bleeding was less than that of the control group and there was the statistically significant difference(P<0.05).Conclusion Compared with the open surgery,laparoscopic surgery can more effectively shorten the recovery time of postoperative intestinal function,reduce the incidence of complications and intraoperative blood loss in elderly patients with CRC.Although there is no significant difference between two kinds of operation mode in terms of radical,it should be considered when it is applied in the specific operation time and other factors.

As a non-atherosclerotic disease in the extracranial segment of the carotid artery, carotid web is a ridge-like intraluminal protrusion beyond the bifurcation of the posterior wall of the carotid artery bulb. Carotid web also has been referred to as an atypical variant of fibromuscular dysplasia. In recent years, more and more studies indicate that carotid web is a rare but important risk factor for ischemic stroke. In order to accurately diagnose carotid artery web, implement targeted intervention and treatment for ischemic stroke caused by carotid web, the authors summarized the recent advances in carotid web and ischemic stroke.
