Objective To evaluate the effect of ultra-filtration extract from Danggui Buxue Decoction (DBD) on immune function of H22 bearing mouse and explore the mechanism through observing the effect of ultra-filtration extract from DBD on the secretion of the cytokines (IL-2,IFN-?).Methods We used membrane separation technique to extract DBD.The content of IL-2 and IFN-? in splenocyte culture supernatant was detected by enzyme-linked immunosorbent assay (ELISA),and the mRNA expression of cytokines (IL-2,IFN-?) in splenocytes was assayed by reverse transcription-polymerase chain reaction ( RT-PCR).Results The content of IL-2 and IFN-? in splenocyte culture supernatant was increased in ultra-filtration extract from DBD groups,significantly in high-dose group (P

Objective To investigate the medium- and long-term effects and safty of Pipeline embolization device ( PED) for the treatment of large and giant intracranial anterior circulation aneurysms. Methods From December 2014 to December 2016,the data of 36 consecutive patients with large and giant aneurysm ( 36 large and giant intracranial anterior circulation aneurysms ) treated with PED in Donglei Brain Doctor Group were analyzed retrospectively. The diameter of the aneurysms was 12 -33 mm, (mean16.6±4.5mm),andthenecksizewas4-10mm(mean6.1±1.5mm).Eightaneurysmswere located in the carotid cavernous sinus segment,22 in the ophthalmic artery segment,5 in the internal carotid artery posterior communicating segment, and 1 in the M1 segment of middle cerebral artery. Seven aneurysms were only treated by PED,28 aneurysms were treated by PED in combination with coil embolization,and 1 aneurysm was treated by double PEDs. The modified Rankin scale ( mRS) score was used to evaluate the prognosis of the patients. Results (1) The clinical prognosis of the patients was followed up by telephone and outpatient department for 6-33 months. Twenty-five patients were followed up by DSA,23 aneurysms (92%) were occluded totally (Raymond gradeⅠ) and 2 (8％) were occluded near totally ( Raymond grade Ⅱ) . ( 2 ) Seven patients were treated with PED alone. Four patients were cured totally after 6 months follow-up,1 was occluded subtotally,2 were not cured;6 were cured in the last follow-up (33 months),and the other aneurysm was gradually reduced;17 of 28 patients treated with PED in combination with coils received DSA follow-up. They were followed up for 6-8 months. All the aneurysms were totally occluded ( Raymond grade Ⅰ) . 1 aneurysm was treated by 2 PEDs, DSA revealed micro-aneurysm-like development at 8 months after procedure. The aneurysms were basically occluded after 15-month follow-up. (3) MRI confirmed after operation that 10 patients had asymptomatic scattered spotted ischemic foci,4 had cerebral parenchymal hemorrhage,1 of them died,1 recovered well after treatment (mRS 1),and the other 2 were asymptomatic cerebral hemorrhage. The occupying effect of 24 cases disappeared, 8 had obvious improvement,and 3 did not have any obvious change. Conclusions The occlusion rate of the treatment of large and giant intracranial aneurysms with PED was high. The results of medium-term follow-up showed that the occlusion rate of PED in combination with coils in the treatment of aneurysms was higher than that of PED alone. The long-term follow-up results showed that the occlusion rate of patients treated with PED alone (including one or more) was gradually increased with time. The safety of the surgery needs to be further confirmed by a large sample study.

Objective To investigate serum levels of lipoprotein-associated phospholipase A2 (Lp-PLA2),high-sensitivity C-reactive protein (hs-CRP),complement component C1q (C1q) and homocysteine(HCY) in patients with Alzheimer's disease(AD),in order to provide a basis for establishing laboratory markers in AD patients.Methods One hundred AD patients and one hundred healthy controls from Beijing Hospital were selected.Serum levels of Lp-PLA2,C1q,hs-CRP and HCY were determined using a biochemistry analyzer.Serum levels of amyloid β-protein 40(Aβ40)and Aβ42 were measured using enzyme-linked immunosorbent assays.Results Serum levels of Aβ40,Aβ42,Lp-PLA2,hs-CRP,C1 q and HCY were higher in AD patients than in the control group[(66.0±14.0) pmol/L vs.(7.1±8.2) pmol/L,(7.2±1.4) pmol/L vs.(1.9±1.7) pmol/L,(510.6±140.1)U/L vs.(419.0±91.8) U/L,(2.8±3.4) mg/L vs.(1.2±0.7) mg/L,(218.0±58.4) mg/L vs.(194.8 ± 27.7) mg/L and (18.8 ± 9.3) μmol/L vs.(14.9 ± 5.2) μmol/L,all P ＜ 0.01],and the differences were greater in female subjects than in male subjectss.Conclusions High serum levels of Lp-PLA2,C1q,hs-CRP and HCY may be associated with Alzheimer's disease,while the exact relationships need to be further investigated.

Objective To evaluate the efficacy and safety of Willis covered stent in the treatment of traumatic carotid cavernous fistulae (tCCF).Methods The imaging and clinical data of 7 patients with tCCF treated with Willis covered stent in Shanghai Punan Hospital from November 2015 to June 2018 were analyzed retrospectively.Results Seven Willis covered stent were used in 7 patients.Immediately after stent release,angiography showed that the fistulae completely disappeared in 6 cases.One patient had a small amount of endoleak,and there was still a small amount of endoleaks after balloon dilatation.It was not further treated.There were no operative complications.During 3-12 months follow-up,no new neurological deficits were found in all patients.Angiographic follow-up of 2 patients showed that the fistulae completely disappeared without recurrence.The internal carotid arteries were patent,no in-stent stenosis and stent displacement.Conclusions Wills covered stent can be used as a treatment for tCCF.Its efficacy is satisfactory and the safety is good.
