Objective To investigate the changes of nuclear factor?B activity in peripheral blood mononuclear cell(PMNC)in newly diagnosed type 2 diabetic patients.Methods Thirty normal individuals and 30 newly diagnosed type 2 diabetics were selected.Phosphorylation status of NF-?B P65 of PMNC was determined by immunoblotting with phosphor-specific antibodies to NF-?B P65(Ser 536 ).Serum hs-CRP was assayed by enzyme linked immunosorbent assay(ELISA).Results The level of NF-?B P65 phosphorylation was increased in newly diagnosed type 2 diabetic patients compared with control subjects[0.85(0.49,1.02)vs 0.47(0.26,0.67),P

Objective To explore the relationship between cerebrovascular steno-occlusive disease and neuropsychological performance by cognitive function assessment.Methods Using a case-control study,45 patients with cerebrovascular steno-occlusive lesions (patient group) and 59 control subjects without cerebrovascular steno-occlusive disease were included,36 simple hypertension (hypertension group)and 34 simple diabetes mellitus subjects (diabetes mellitus group) without cerebrovascular steno-occlusive disease were also included.A battery of neuropsychological was performed in all subjects.The test battery included tests of memory,executive functions,mental speed,visuospatial ability and visuoconstructive skill,anxietas and depression.Results Patient group showed impairments in multiple cognitive domains compared with other three groups.The immediate recall of auditory verbal learning test (controls 56.8 ± 6.5 ;patient group 48.5 ± 10.1 ;hypertension group 53.5 ±9.0 ;diabetes mellitus group 55.9 ± 7.9;t =-3.57-4.822,P =0.000-0.021) were impaired seriously.Moreover,visual memory Modified Rey-Osterrieth Complex Figure Test immediate recall,long time delayed recall and executive function California cards sorting test were also impaired.Patient group was divided into two subgroups,and neuropsychological tests of these subgroups were compared.Multiple stenosis subgroup had significantly worse performance in tests of verbal memory and some executive functions than the single artery stenosis subgroup.Conclusions Cerebrovascular steno-occlusive disease was associated with poorer neuropsychological performance,which could not be explained by vascular risk factors.Multiple stenosis subgroup had lower performance levels in neuropsychological tests than simple stenosis subgroup.Ischemia or hypoperfusion caused by steno-occlusive disease might be responsible for these cognitive impairments.

Objective To investigate the characteristics of imaging appearances and diagnostic value of ciliochoroidal detachment.Methods Ultrasound,MRI and CT appearances of 19 cases of ciliochoroidal detachment were reviewed,which included 9 cases of serous ciliochoroidal detachment,7 cases of choroid hematoma,and 3 cases of ciliary body detachment.All cases were examined by both B ultrasound and MRI at the same time,11 of them were examined by CT.Results UItrasound showed membrane bulge of the eyeball wall with different extent in 9 cases of serous ciliochoroidal detachment.Its postzone connected the equator or close to optic disc and its prozone could not been detected by ultrasound.There was echofree fluid darkspace under detached membrane.MRI showed membrane detachment at both nasal side and temporal side of ocular annulation in 9 cases of ciliochoroidal detachment.The detached membrane was approximately symmetry,its anterior margin did not exceed ciliary body adhesion of ocular annnlation and its posterior margin stopped at posterior part of ocular annulafion.There was long T1 and long T2 signal under detached membrane.CT showed slight thickening of ocular annulafion and slightly increased density of eyeball in 5 cases of serous cilioehoroidal detachment.Ultrasound showed hemispheroid or curve bulge of eyeball wall,projected toward the vitreous cavity in 7 cases of choroid hematoma,and there was an amount of low echo light spot under the detached membrane.Both MRI (7 cases)and CT (5 cases) showed hemispheroid,fusfform or curve bulge on the nasal side,temporal side and posterior part of ocular annulation.They appeared as isodensity or slight high density on CT,iso- or high signal on T1 WI and T2WI.Stratification was seen on T2WI in I case of choroid hematoma.Ciliary body detachment could not been detected by either MBI (3 cases) or CT (1 case) except ultrasound.Conclusion Imaging examination may provide reliable diagnostic evidence for ciliochoroidal detachment.

Objective To elucidate the analgesic activity of the ethanol extracts from the root of Daphne genkwa (EERD). Methods The analgesic activity of EERD was evaluated by the effects on adjuvant-induced nociceptive response and paw swelling, the formation of PGE_2 and IL-1? in adjuvant arthritis (AA) rats, the activities of SOD and CAT, the levels of NO/iNOS in serum and brain tissue as well as by the effects on c-Fos protein expression in spinal cord of AA rats. Results EERD at used doses significantly delayed the adjuvant-induced nociceptive response and eased the paw swelling in AA rats. EERD also evidently inhibited the production of PGE_2 and IL-1?, and enhanced the activities of SOD and CAT in the tissue of paws being injected by adjuvant. Furthermore, it remarkably reduced the content of NO and inactivated the activity of iNOS in brain tissue of AA rats. In addition, EERD at used doses exhibited prominent inhibition on adjuvant-induced expression of c-Fos protein in the spinal cord of AA rats. Conclusion EERD is an effective agent for analgesia. The possible mechanisms for its analgesia might be the actions of inhibiting the production of PGE_2 and the release of IL-1?, reducing the activity of iNOS and hence the generation of NO in brain tissue, and blocking superoxidation through enhancing the activity of SOD and CAT.

Background Cytokines play a crucial role in mediating immune tolerance or immune rejection of corneal transplantation.However,the study on the expression of cytokines in corneal graft is seldom.ObjectiveThe purpose of the study is to investigate the change of cytokine expression in allografts at different time points after corneal transplantation.Methods BALB/c and C57BL/6 mice aged 6 to 8-week old were used to establish autologous and allografts keratoplasty models.BALB/c mouse was use as donor and receipt in autologous group,and the cornea of C57BL/6 mouse was used to graft on the BALB/c mouse in the allografts group.The graft inflammation was clinically scored,and graft inflammatory scores of ≥5 or opaciflcation scores of ≥2 were identified as rejection.BALB/c mice were randomized into normal control group(3 mice)and allografts group(15 mice).Reverse transcriptPCR (RT-PCR) was used to detect the expression of interleukin-4 (IL-4) mRNA,interferon-γ (IFN-γ) mRNA,IL-10mRNA and tumor necrosis factor(TNF-α) mRNA in graft 6 hours and 1 day,3,7,14 days after operation.Results The corneal graft opacification score was ＜2 and inflammatory score was ＜5 in the 10 mice with autologous keratoplasty until 60 days with the survival rate 100％.The edema,opacification and new blood vessel were seen in the BALB/c mice received allografts keratoplasty.The inflammatory score was ≥ 5 and the opacification score was ≥2 24 days after surgery with the rejection rate 100％,in the allografts group,and the graft survival time was (17.80±4.66)days.RT-PCR showed that IL-4 and IFN-γ were positively expressed,and IL-10 and TNF-α were absently expressed in normal mouse cornea.In the allografts keratoplasty mice,positive responses for IL-4,IFN-γ and IL-10 were found in 6hours after operation,but TNF-α was absent.From 1 day through 3 days after operation,the expressions of IL-4,IFN-γand TNF-α were enhanced but IL-10 was disappeared in the graft.IL-10,IFN-γ and TNF-α were expressed till the 7th day,but on the 14th day,only IL-10 was detected in graft in the allografts keratoplasty mice.Conclusions TNF-αis a main factor among the variety of cytokines that may influent corneal allograft rejection locally.

Objective:To explore the curative effect of Penumbra retrograde semi-retrieval Solitaire stents technique in the treatment of acute basilar artery occlusion.Methods:The clinical data of 15 patients with acute basilar artery occlusion in Shengjing Hospital of China Medical University from January 2017 to December 2019 were analyzed retrospectively. All patients were treated with Penumbra retrograde semi-retrieval Solitaire stents technique. The modified thrombolysis in cerebral infarction (mTICI) was used to evaluate the therapeutic effect.Results:Fifteen patients achieved vascular recanalization of occluded basilar artery, and mTICI 2b grade was in 3 cases, 3 grade in 12 cases. One operation completed vascular recanalization in 11 cases, 2 times in 3 cases,3 times in 1 case. CT images 24 to 48 h after operative showed no intracranial hemorrhage. The National Institutes of Health stroke scale (NIHSS) score at discharge was significantly lower than that before surgery: (4.8 ± 2.1) scores vs. (16.1 ± 5.7) scores, and there was statistical difference ( P<0.01). Conclusions:Penumbra retrograde semi-retrieval Solitaire stents technique can improve the efficiency of thrombus grasping and significantly improve patient symptoms.

Objective To observe the therapeutical effect of posterior vertebral column resection on chronic thoracolumbar tuberculosis with secondary paraplegia and to provide a safe and effective method for the treatment of chronic thoracolumbar tuberculosis with secondary paraplegia.MethodsFrom Aug.2007 to Mar.2010,12 cases with chronic thoracolumbar tuberculosis and secondary paraplegia were surgically treated by posterior vertebral column resection and Titanium net support for bone graft and internal fixation operation treatment.Cobb angle was measured,and conditions of internal fixation were observed before and after the operation by X-ray films.Neurological status were evaluated by Frankel grades.ResultsThe follow-up periods was 6- 18 months( on average 11 months).Operations eased all patients' back and chest pain.Frankel grade increased from C preoperatively to grade D or E postoperatively in 6 cases,from grade D to E in 4 cases and from grade B to C in 1 case.No obvious improvement of Frankel grade was observed in the other patient of grade B.The average Cobb angles were(76.0 ± 23.4) ° before surgery,( 15.5 ± 6.3 ) ° at one week after surgery and ( 16.0 ± 8.2) °at the last follow-up.The difference in the Cobb angle before and at one week after treatment was significant( t =3.41,P ＜ 0.01 ).No difference was found in the Cobb angle between at one week after treatment and at the last follow-up (t =1.58,P ＞ 0.05 ).All patients got bony fusion with Titanium net.No complications occurred with internal fixation.Conclusion Posterior vertebral column resection is a feasible method for the treatment of chronic thoracolumbar tuberculosis with secondary paraplegia.It achieves neurological decompression with high correction rate and minor injury,and no anterior surgery is needed.
