Objective To detect the expressions of high mobility group box-1,nuclear factor-kB(NF-kB)in tumor tissues of glioma patients and analyze the correlation of HMGB1 and NF-kB expressions with tumor pathology. Methods A total of 76 patients who undertook glioma resection were selected as observation group,and 20 patients who undertook intracranial decompression were selected as control group during September 2013 to September 2017. The expressions of HMGB1 and NF-kB were detected by SP immunohistochemistry(SP)and analyzed by combining clinical factors and postoperative tumor pathology to investigate the relationship between the expression levels of HMGB1 and NF-kB and the pathology of glioma. Results The positive expression rates of HMGB1 and NF-kB in glioma tissues of the observation group were both higher than those of the control group(P<0.05). The expression levels of HMGB1 and NF-kB in glioma tissues were observed in the observation group. The pathological grade of the tumor was related(P<0.05). Expression levels of HMGB1 and NF-kB in glioma tissue of the trial group were related with pathological grade of glioma(P<0.05). In the observation group,HMGB1 expression level was positively correlated with NF-kB expression level(r=0.316,P<0.05). Conclusion HMGB1 and NF-kB are significantly higher in glioma tumor specimens than normal tissues,and the expression of HMGB1 and NF-kB is correlated with tumor pathological grade,suggests that may be closely related to the occurrence and pathology of glioma.

Objective To study the disposal methods for syphilis Infections during the health check of entry-exit people.Method To analyze the status of test methods for syphilis in Laboratory,the status of the treatment procedures of syphilis for the health check of entry-exit people,and the results of corresponding research.Result At present,there was no high sensitivity and specificity shown in the laboratory results which can reflect the infectiousness of syphilis(especially after treatment) as the basis whether the health certificate may be issued to the syphilis infections,but the therapy efficacy of penicillin for syphilis was sure with the cure rate at almost 100%.Conclusion The basis of issuing health certificates to the syphilis infections should be whether having received regular antisyphilis treatment.
Objective To evaluat the application value of TRUST for diagnosing latent syphilis. Method 165 serums of TPPA positive were tested by using TRUST and TP-IgM anitibodies,and both the case history and therapy status were investigated.Follow-up was then carried out. Result TP-IgM anitibodies were all negative among the serums of the 64 personnel of which TPPA was positive and TRUST was negative.No clinical symptoms or signs were found among the 26 personnel who came to accept follow-up, the TRUST and the TP-IgM anitibodies were all negative as well;Only one of the TP-IgM anitibodies was positive among the serums of the 19 personnel of which TPPA was positive and TRUST was a borderline reaction.Four of the TRUST changed to negative and the TP-IgM anitibodies (including the one of which TP-IgM anitibody was originally positive) all were negative among the 11 personnel who came for a follow-up,No clinical symptoms or signs were found either;TP-IgM anitibodies few were positive when the TRUST titers were under 1:4 among the serums of the 82 personnel of which TPPA and TRUST were all positive.Though no clinical symptoms or signs were found,but only nine of the TRUST changed to either a borderline reaction or negative among the serums of the 43 personnel of which TPPA was positive and TRUST was positive after they had accepted standard treatment. Conclusion The negative results of TRUST are reliable;The positive results of TRUST(getting rid of the false positive of biology) are trustworthy before the patients with syphilis accepted treatment,But the positive results of TRUST cann’t reflect reality state of Syphilis after they have accepted standard treatment.

脑血管痉挛是蛛网膜下腔出血后严重的并发症,半个世纪以来一直是研究热点[1].目前,脑血管痉挛发生的病理生理机制仍然很不明确,有关内皮素-1(Endothelin-1,ET-1)的研究较多[2].作者动态检测脑脊液中ET-1浓度以期进一步探讨血管痉挛的发生机制及ET-1的作用.
颅脑损伤者常伴有各种不同程度的呼吸功能障碍,这是颅脑损伤后一系列病理生理改变的重要因素之一.一般临床常压吸氧难以纠正缺氧,同时呼吸道梗阻气管切开、深昏迷、病情危重的患者不适宜做高压氧舱.笔者采取氧合液静脉输入,纠正体内缺氧及脑缺氧,增加需氧含量,提高氧分压,在颅脑外伤早期,应用氧合液治疗的基础和临床研究鲜有报道.2004年9月至2005年6月,笔者采用双盲对照实验的方法治疗了50例急性颅脑损伤患者,取得较好疗效.现报告如下.
阵发性室上性心动过速(PSVT)为临床上常见的快速心律失常,90%由折返所致,多数可用药物终止,如未及时终止发作,可给患者造成痛苦,甚至危及患者生命.本组18例23例次PSVT发作患者,分别因三磷酸腺苷(ATP)、普罗帕酮静注无效,采用食管调搏超速抑制而使发作终止.
Objective:To investigate the effects of carvedilol and metoprolo l on left ventricular hypertrophy and microproteinuria in the treatment of essential hypertension(EH).Methods:One hundred and four outpaˉtients with EH1and2were randomized into two groups and treated with carvedilol(20~40mg/d,groups A)and metoprolol(50~100mg/d,group B)for24weeks respectively.The levels of interventricular septal thickˉness(IVST),left ventricular posterior wall thickness(LVPWT),left ventricular mass indexes(LVMI),α 1 -miˉcroglobulin(α 1 -MG)and microalbuminuria(Alb)were measured before and after the treatment.Thirty subjects with normal blood pressure were selected randomly to serve as control group.Results:Compared with the control group,all markers were elevated in group A and B before the treatment(P0.01).The blood pressure and heart rate significantly decreased in group A and B after the treatment(P0.01),and the heart rate decreased significantly in group B than that in group A(P0.05).There was no significant difference in IVST,LVPWT,LVMI,α 1 -MG and Alb between group A and control group after the treatment(P0.05),and all these markers were significantly higher in group B than that in control group(P0.05).LVPWT,LVMI ,α 1 -MG and Alb decreased in group A after the treatment(P0.01),and there was no significant change in IVST(P0.05).There was no significant change in all markers in group B after the treatment compared with that before the treatment(P0.05).Conclusion:Carvedilol and metoprolol may play a satisfactory role in the treatment of EH,but carvedilol has more advantages in protecting the damage of target organs compared with metoprolol in patients with EH.
