METHODS:27 ADR reports induced by Magnesium isoglycyrrhizinate injection from Hunan Center for ADR Monitoring from Jan. 2014 to Mar. 2015 were retrospectively analyzed. RE-SULTS:In the 27 cases,15 were male (55.56%) and 12 were female (44.44%),with percentage of 1.25∶1;ADR mainly oc-curred in patients with 41-60 years old(51.85%);involved organ/system were mainly skin and its appendages(35.85%)and sys-temic damage(26.42%),the main clinical manifestations were rash,itching,fever,chills,vomiting and dizziness;there were 7 severe ADR reports(25.92%),mainly showed chills,fever and other systemic symptoms;most ADR can be cured(40.74%)or relieved(55.56%)by related processing. 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 describe survival of patients with aneurysm subarachnoid hemorrhage (aSAH) and its related factors. Methods Data of 88 patients with aSAH were analyzed retrospectively, including their age, gender, past medical history, therapeutic measures, complications and prognosis, and so on. Their survival and its related factors were identified by Kaplan-Meier method and COX proportional hazard regression model. Results Eighty-eight patients were followed-up for a total of 141. 9 person-year,with an average of (1.6 ?.0) years, and the longest of 5. 6 years. Survival was 78 percent, 73 percentand 68 percent in the first month, first year and 2. 5 - 5. 6 years after onset, respectively. Administration ofnimodipine (RR = 0. 981, 95 % CI = 0. 965 - 0. 997, P = 0. 023) was potential protective factor for deaths caused by aSAH. Compared with conservative medical treatment, both surgical occlusion (RR =0. 147, 95% CI = 0. 041 - 0. 532, P = 0. 003) and intervention embolotherapy (RR = 0. 221, 95% CI = 0. 060-0. 823, P= 0.024) were also protective factors. However, complications such as hyponatremia, pulmonary infection, alimentary tract hemorrhage (RR = 1. 965, 95% CI - 1. 404 - 2. 748, P ＜ 0. 05) and cerebral vasospasm (RR = 2. 951, 95% CI = 1. 473 - 5. 911, P = 0. 002) were independent risk factors for aSAH.Conclusions Prognosis in patients with hyponatremia, pulmonary infection, alimentary tract hemorrhage and cerebral vasospasm is unfavorable, and aneurysm occlusion by surgical operation, embolotherapy andadministration of nimodipine all can decrease fatality caused by aSAH.

Objective To determine the diagnostic value and necessity of excretory phase of CT urogrphy (CTU). Methods One hundred and one cases with 197 sides of cohort CTU studies were enrolled from PACS system retrospectively, and 44 cases had the records of radiation dosage. Three different seniority senior radiologists reviewed the images and diagnosed 2 times blindly with the clinical information. At the first time, plane scan, contrast enhanced renal cortical phase and renal parenchymal phase images (Diag. A) were reviewed. At the second time, with 3 kinds of images mentioned above plus excretive phase images (Diag. B) were reviewed, with interval of 3 months between the two reviews. With Diag. B as reference standard, accordance rate of diagnoses of Diag. A was calculated. The difference of the 3 rediologists's accordance rates were analyzed with Chi-square test, and the lesions with accordance rate ≤80% were recorded. The cases of 197 urinary tracts were divided into 4 groups: lesions of renal pelvic and ureter, lesions of bladder, lesions of kidney and extra-urinary tract, without lesion. The filling of contrast media in the urinary tract was recorded with 5-scale scoring system. The differences of the urinary tract filling among the 4 groups were analyzed with Kruskal-Wallis test. The effective radiation dosages of CTU with and without excretory phase scan were recorded and calculated, and the difference was analyzed with t test. Result The diagnostic accordance rate of CTU with and without excretory phase of the 3 radiologists was 95.4%(188/197), 93.9%(185/197), 92.4%(182/197)respectively(χ2=1.60, P>0.05). Lesions with diagnostic rate≤80%were parapelvic cyst and caliceal diverticulum. The median score of urinary tracts filling in the lesions of renal pelvic and ureter, lesions of bladder, lesions of kidney and extra-urinary tract, without lesion group were 2, 3, 3, 4, and the differences were significant (HC=31.7, P<0.05). The effective radiation dosages of CTU with and without excretory phase scan were (32.36±11.04)mSv and (41.47±14.27) mSv respectively (t=3.35, P<0.01). Conclusions No significant effect of excretive phase imaging is found on the diagnosis of most urinary system diseases. Poor contrast filling and high rate of failure of filling of the urinary tract with intra luminal pathologies, and increase of the radiation dosage make the excretory phase scan in CTU less useful and it should be used carefully and selectively.

Objective To investigate the role of quorum sensing Escherichia coli regulator C (qseC) in intestinal bacterial translocation in rats subjected to hemorrhagic shock.Methods Thirty Sprague-Dawley rats,weighing 250-300 g,were randomly divided into 5 groups (n =6 each):control group (group C),MC1000-sham shock group (group M-SS),MC1000qseC-sham shock group (group △-SS),MC1000-hemorrhagic shock group (group M-HS),and MC1000△ qseC-hemorrhagic shock group (group △-HS).The rats drank 150 μg/ml of disinfect water containing streptomycin in 3 consecutive days to inhibit the autochthonous flora in the intestinal tract.From 4th day,the rats were fed with Escherichia Coli MC1000 or MC1000△ qseC 1 ml/100 g by gastric perfusion once a day for another 3 consecutive days in the other 4 groups,while the rats were fed with normal saline instead in group C.Hemorrhagic shock was induced by blood-letting.The mesenteric lymph node (MLN),spleen and liver specimens were obtained at 24 h after operation for bacterial culture and the bacteria were identified.Bacterial translocation from gut to MLN,spleen and liver was observed and the number of bacteria in MLN,spleen and liver tissues were counted.Results The rate of bacterial translocation was significantly higher,and the number of bacterial colonies in MLN,spleen and liver tissues and the total number of bacterial colonies were significantly larger in groups M-HS and △-HS than in group C,and in group M-HS than in groups M-SS and △-SS (P ＜ 0.05).The rate of bacterial translocation was significantly lower,and the number of bacterial colonies in MLN,spleen and liver tissues and the total number of bacterial colonies were significantly smaller in group △-HS than in group MHS.Conclusion QseC is involved in the intestinal bacterial translocation following hemorrhagic shock in rats.

Aim Neural injury in the central nervous system following is chemic insult is believed to result from oxygen and glucose deprivation.In this study,baicalin was investigated for its neuroprotective effects against oxygen and glucose deprivation(OGD) in Neuro2A cells.Methods Mitochondrial activity was assessed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide(MTT) reduction activity assay.Apoptosis was monitored with flow cytometry.It was found that baicalin increased MTT reduction activity and decreased percentage of apoptosis of the cultured Neuro2A cells.Results Baicalin showed significant protective effects on the OGD-induced apoptosis in cultured Neuro2A cells.Conclusion These results suggest that baicalin is an effective compound in preventing neurotoxicity induced by OGD and therefore deserves further scrutiny.

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.

Objective To evaluate the accuracy of the delay time after contrast media administration in intracranial CTA study during brain CT perfusion study.Methods 14 patients with history of episodes of typical transient ischemic attack(TIA)or ischemic cerebrovascular disease were included.After cerebral CT perfusion study,the CTA study of Willis circle was performed with the delay time by measuring the different value between the time to peak(TTP)and beginning scan time of anterior cerebral artery in CT perfusion.The quality of the CTA images were evaluated.Results All the CTA images of the Willis circle were satisfactory.Conclusion It's a satisfactory method based on successful cerebral CTA study to take the time to peak in CT perfusion as the delay time.

Objective To construct an Apoptin prokaryotic vector,aiming to produce antigenic fusion protein Apoptin. Methods The Apoptin gene was amplified from the template of plasmid pSSCHG/NT4-Apoptin-HA2-TAT by PCR.The Apoptin was sub-cloned into the multiple clone sites of plasmid pET-28a(+) to get the prokaryotic vector of pET-28a(+)-Apoptin,which was transformed into E.coli BL21(DE3).Expression of E.coli BL21(DE3) was induced by IPTG.The specific protein expression was detected by SDS-PAGE. Results The fusion protein was expressed with high efficiency in E.coli BL21(DE3) transformed by pET-28a(+)-Apoptin after induction with IPTG.The specific fusion protein had an apparent related molecular weight of about 17 000 ku as indicated by SDA-PAGE analysis. Conclusion The Apoptin prokaryotic expression vector with pET-28a(+)-Apoptin can effectively express Apoptin fusion protein,laying a foundation for further study of Apoptin and preparation of antibodies against Apoptin.
