ABSTRACT
Objective:To explore the clinical effect of endoscopic assisted or microscopical transsphenoidal surgery in the treatment of different grades of invasive pituitary tumors and the measures to reduce complications.Methods:From January 2016 to June 2019, 87 patients with pituitary tumor admitted to the neurosurgery of Tangshan People′s Hospital of Hebei Province were selected as the study objects for retrospective analysis. Among them, 42 patients were included in the endoscopic group and 45 patients were included in the endoscopic group. To compare the related indexes and clinical effects of two different surgical methods, and to analyze the treatment strategies to reduce the common postoperative complications.Results:The amount of intraoperative bleeding, the time needed for operation and the hospital stay of patients in endoscopic group were significantly less or shorter than those in microscopical group(intraoperative bleeding volume: (66.19±9.55) ml and (79.78±11.68) ml; operation time: (93.93±9.53) min and (103.33±9.23) min; hospitalization time: (7.71±1.53) d and (10.16±1.33) d). The difference was statistically significant (T values were 5.92, 4.67, 7.94, all P< 0.01). There was no significant difference between the two groups ( P= 0.577). There were 2 cases (4.8%) of cerebrospinal fluid leakage in endoscopic group and 12 cases (26.7%) in microscopical group. The difference between the two groups was statistically significant(χ 2=5.67, P< 0.05). There were 7 cases (16.7%) of diabetes insipidus in endoscopic group and 22 cases (48.9%) in microscopical group. The difference between the two groups was statistically significant (χ 2=5.19, P< 0.05). Conclusion:The curative effect of endoscopic transsphenoidal resection of pituitary tumor is similar to that of microscopical resection of pituitary tumor. The patients recover quickly, have fewer complications, and have a short hospital stay.
ABSTRACT
Objective To investigate the expression of beclin1 and LC3 in non small cell lung cancer and explore their clinical significance. Methods Immunohistochemistry was applied to confirm expression of Beclin1 and LC3 in 66 samples of NSCC and 52 samples of adjacent tissues. Clinical pathological features were analyzed. Results Beclin1 and LC3 expression were lower in cancer tissues than that in adjacent cancer tissues ,and the dif-ference was statistically significant(46.9%vs 75%,53%vs 80.7%,P<0.05). The expression of Beclin1 and LC3 was down-regulated with TNM staging rising and tissue differentiation decreasing. With tumor enlarging ,Beclin1 down-regulated,and the difference is statistically significant(P<0.05). Expression of Beclin1 was positively cor-related with LC3 expression(r=0.31,P<0.05). Conclusion The down-regulation of autophagy-related protein Beclinl and LC3 might be involved in the genesis and development of non small lung cancer.
ABSTRACT
OBJECTIVE To understand the portable blood sugar meter′s blood sampling gun contaminated by hepatitis B-type virus,and to discuss the effect of two kinds clinical commonly used disinfection methods. METHODS The blood sampling gun of blood sugar meter was checked before and after 75% alcohol or 1% chlorine-containing disinfectant disinfection. RESULTS Before disinfection of the gun their were 35 samples from 47 lotions in disinfection with positive HBV-DNA,between two kinds of disinfectants were significant difference. CONCLUSIONS The blood sugar meter′s blood sampling gun contaminated by hepatitis B-type virus is seriously,75% alcohol is no use to disinfect the gun.It is suggested to supply two blood sampling guns per one blood sugar meter and use 1% chlorine-containing disinfectant for its disinfection of gun after its use in order to avoid the cross infection.
