Objective To investigate the risk factors related to cerebral vsospasm in patients with aneurysmal subarachnoid hemorrhage (aSAH).Metrods The risk factors related to cerebral vasospasm in 88 patients with aSAH were identified through the multivariate logistic regression analysis and Cox analysis, including demographic factors, healthy habits, past mescal history, acute stress factors, acute complications, acute evaluation indexes, treatment time, therapeutic measures, and hemorrhage involving brain regions. Results Drinking history (OR=1.077,95%CI 1.015-1.142;P=0.014)was an independent risk factor for cerebral vasospasm before admission. Histories of smoking(RR=1.031,95%CI 1.001-1.063:P=0.042),diabetes mellitus(RR=1.333,95%CI 1.100-1.614;P=0.003)and hypertension (RR=1.066,95%CI 1.008-1.127;P=-0.024)were the independent risk factors for cerebral vasospasm during hospitalization. The increased leukocyte count(RR=1.117,95%CI 1.039-1.200;P=0.003)was a predictive factor for cerebral vasospasm; the administration of Nimotop(RR=0.990,95%CI 0.979-1.001;P=0.088)significantly decreased the risk of cerebral vasospasm;the blood glucose lexels in acute stage were not associated with the occurrence of cerebral vasospasm(RR=1.076,95%CI 0.968-1.196;P=0.175);there was no significant difference between endovascular embolization group and surgical clipping group in the risk of cerebral vasospasm(RR=0.792,95%CI 0.322-1.950;P=0.612).Conclusions The risk of cerebral vasospasm increased significantly in patients with aSAH who have the histories of long-term drinking, smoking, diabetes mellitus, hypertension as well as increased leukocyte count. The administration of Nimotop may significantly decrease the risk of cerebral vasospasm

Background and purpose:Inadequate surgical operation of gastric cancer may cause introgenic tumor cell dissemination and peritoneal seeding.This study introduced a new technique of the interrupted procedure to prevent gastric cancer cells dissemination in the radical resection of gastric cancer.Methods:Patients received gastric interrupted procedure employing the use of gastric interrupted forceps in the carcinoma of antrum,gastric body or cardia.The interrupted effect,complicated nature of the procedure and the preliminary result of CK19 mRNA expression in the portal blood by RT-PCR techniques of the interrupted group and the routine operation group were analyzed.Results:All the patients were successfully interrupted in the gastric operation,but there were some differences in the detailed procedure between the carcinoma of antrum,gastric body and cardia.Special attention should be given to the prevention of spleen scrape via the interrupted forceps,and to the posterior gastric trauma in case there is adhesion between the stomach and pancreas.Nine patients (9/17) of the routine operation group have positive portal blood CK19 mRNA expression whereas all 17 patients have negative portal blood CK19 mRNA expression in the interrupted group.Conclusion:The interrupted procedure is an easy,useful and safe method of manipulating and to preventing a large amount of gastric cancer cells from disseminating in the portal blood during the radical operation of gastric cancer.

Objective:To investigate the diagnostic value of microRNA-19(miR-19)and microRNA-21(miR-21)in elderly patients with differentiated thyroid carcinoma(DTC), and to analyze the relationship of miR-19 and miR-21 expression with pathological characteristics in elderly patients with DTC.Methods:A total of ninety-six elderly DTC patients visiting our hospital from January 2015 to January 2018 were included in this retrospective study.They underwent cervical lymph node puncture biopsy and radical surgery for thyroid cancer.The expression levels of miR-21 and miR-19 were detected in lymph node tissues, thyroid cancer tissues and normal para-cancerous tissue.The differences in miR-21 and miR-19 expression levels between three different pathological tissues in elderly patients were analyzed.The correlation of miR-21 and miR-19 expression levels with different clinico-pathological features in elderly patients was observed.Results:The expression levels of miR-21 from low to high were(0.92±0.33)in para-cancerous tissue, (3.41±0.64)in lymph node tissue and(4.28±1.56)in DTC tissue respectively( F=296.683, P<0.01), the difference was statistically significant( F=296.683, P=0.01). While, there was no significant difference in the expression levels of miR-19 among different tissues( P>0.05). Spearman correlation test showed that the expression level miR-21 in DTC tissue was positively correlated with that in lymph node tissue and para-cancerous tissue( r values were 0.724, 0.801, all P<0.01), while the expression level of miR-19 showed no correlation of DTC tissues with lymph node and para-cancerous tissues( r=0.127 and 0.165, P>0.05). The expression level of miR-21 in lymph node tissue was positively correlated with that in para-cancerous tissues( r=0.705, P<0.01), but the expression level of microRNA-19 had no correlation between the two kinds of tissues( r=0.191, P>0.05). There was no significant difference in the expression of miR-21 in cervical lymph nodes among patients with different gender and tumor diameter( P>0.05). The expression level of miR-21 in cervical lymph nodes was significantly higher in stage Ⅲ patients than in stage Ⅰ-Ⅱ patients( P<0.05). The expression level of microRNA-21 in cervical lymph nodes was higher in patients with extra-glandular infiltration than without extra-glandular infiltration( P<0.05). The expression of microRNA-19 in cervical lymph nodes showed no significant difference regardless of sex, tumor diameter, tumor stage, extra-thyroid invasion. Conclusions:MiR-19 may not be involved in the development of DTC in elderly patients, and microRNA-21 may play an important role in the development of DTC in elderly patients, especially in the process of tumor invasion and metastasis.Early cervical lymph node puncture for miR-21 detection helps early diagnose and evaluate DTC, to provide a basis for the choice of treatment options.

CONCLUSIONS:There are no risk tips for severe allergic reactions in instruction,it is necessary to strengthen post-marketing surveillance and further improve the drug instructions to reduce the risk of severe ADR in-duced by Magnesium isoglycyrrhizinate injection.

Objective:To investigate the relationship between dopamine D1 receptor ( DRD1 ) gene polymorphisms and clozapine efficacy in male schizophrenic patients. Methods:Totally 46 male schizophrenic patients were treated by clozapine for 6-8 weeks. The clinical response was determined by the Positive and Negative Symptom Scale (PANSS). DRD1 gene rs265981, rs5326, rs4532, rs1799914, rs686 and rs4867798 polymorphisms were detected by the gene sequencing, while plasma clozapine levels were monitored during the treatment. Results:The total clinical efficacy of clozapine response group and the non-response group was compared, the distribution of rs265981 genotype TT, TC and CC and allele T and C had statistically significant differences (P=0. 025;P=0. 005), and the distribution of rs686 genotype CC, CT and TC and allele C and T had statistically significant differences ( P=0. 044;P=0. 010). The negative symptom of the response group was compared with that of the non-response group, the distribution of rs4532 gen-otype GG, GA and AA and allele G and A had statistically significant differences (P=0. 034; P=0. 013). Conclusion: The poly-morphisms of DRD1 gene rs265981 and rs686 may have influence on the clinical efficacy of clozapine, and rs4532 may have influence on the negative symptom.

Objective To evaluate the diagnostic performance of real-time contrast-enhanced ultrasound (CEUS)in characterizing complex cystic focal liver lesions(FLLs).Methods Sixty seven complex cystic FLLs in 65 patients were examined with baseline ultrasound(BUS)and CEUS.BUS and CEUS images were reviewed by a resident radiologist and a staff radiologist independently.Diagnostic performance was evaluated using receiver operating characteristic(ROC)analysis and the interobserver agreement was analyzed by weighted k statistics.Results After ROC analysis,the areas under the ROC curve(Az)were 0.917 for the staff radiologist and 0.774(P=0.044)for the resident radiologist on BUS,and were 0.935 and 0.922(P=0.42)on CEUS.A significant difference in Az between BUS and CEUS was found for the resident radiologist(0.774 versus 0.922,P=0.047),whereas not found for the staff radiologist(0.917 versus 0.935,P=0.38).Better results of specific diagnosis were obtained on CEUS[28.4%(19/67)before versus 58.2%(39/67)after review of CEUS images for resident radiologist,and 26.9%(18/67)versus 76.1%(51/67)for staff radiologist,both P＜0.001].Interobserver agreement was improved after review of CEUS images[K=0.325(95%confidence interval:0.214-0.436)on BUS versus k=0.774(95%confidence interval:0.688-0.860)on CEUS].Conclusions Real-time CEUS improves the capability of discrimination between malignant and benign lesions and specific characterization for complex cystic FLLs,as well as the interobserver agreement.

Objective To study the effect of epinephrine on biofilm formation of the qseC-deleted mutant of Escherichia coli on biomaterial.Methods The strains used in this study are Escherichia coli MC1000 and MC1000AqseC.LB was used for all the experiments.To determine the effect of epinephrine on motility,halos were measured in LB medium at 37℃ in the presence of epinephrine(50 μmol/L).LB with epinephrine and without epinephrine were used,and then the experiment of bacterial biofilm formation on PVC material was taken.The relative amount of biofilm was estimated.The thickness of bacterial community and bacterial community quantity in the unit area on PVC materials were measured by confocal laser scanning microscope( CLSM),and the surface structure of biofilm formation was observed by scanning electron microscope(SEM).Results The mutant strain formed less biofilm than the wild-type strain in LB.The increment in motility of wild-type strain due to epinephrine addition was shown,but mutant strain is unaffected.Similarly,biofilm formation of the wild-type strain was increased by epinephrine,but epinephrine did not affect the biofilm formation of the qseC mutant.The CLSM and SEM showed that epinephrine stimulated biofilm formation of wild-type strain on PVC materials,but had no effect on qseC-deleted mutant strain.Conclusion Epinephrine increases Escherichia coli biofilms on biomaterials through qseC.
