The gene sequence was analyzed by DNAstar software and GenBank database. Results Nine positive clones were identified by immunoscreening. The clone Ts87 was sequenced and a cDNA with 1 172 bp full length was obtained using 5′ RACE technique, encoding 347 amino acids. Some possible antigen epitopes were predicted. Conclusion A novel antigenic gene of Trichinella spiralis was obtained.

Objective To explore the methods of labeling exogenous microglia with superparamagnetie iron oxide(SPIO)particles,and to monitor the labeled cells after transplantation into the normal rat and Alzheimer's disease(AD)model rat with MR scanning.Methods Microglia was labeled with SPIO particles by using transfection agent,hemagglutinating virus of Japan envelope(HVJ-E).Then the microglias which were labeled with SPIO were injected into the internal carotid artery of normal rat (n=5)and AD model rat(n=5).Three days after transplantation,follow-up serial T2*-weighted gradient-echo MR imaging was performed at 7.0T MRI system.MR images were correlated with histological findings.Results In the brain of normal rat,the labeled microglias were demonstrated as several dotty signalintensity decrease on T2*-weighted MR images.The dotty spots were sporadic around the brain.Histological analysis showed that most prussian blue staining-positive cells were well correlated with the area where a signal intensity decrease was observed in MRI.MR could detect the signal intensity change caused by a few labeled cells.In the brain of AD model rat,MR scan showed a well-defined hypointensity area in the region of Aβ42 iniection.Signal intensity decrease was not obvious in the region of saline injection.The number of iron-positive cells(454±47)/mm2 at sites of Aβ42 injection was much higher than that(83±13)/mm2 of saline injection(P＜0.05). Conclusion MR can be used as a non-invasive means of detecting transplanted labeled microglia in vivo,with the potential for future clinical application in cell therapy of AD.

Objective To study the clinical effect of nourishing kidney, securing essence and cooling blood on incipient diabetic nephropathy. Methods A total of 110 patients with incipient diabetic nephropathy were randomly recruited into a treatment group and a control group. The treatment group was treated with the method of nourishing kidney, securing essence and cooling blood and benazepril hydrochloride tablets. The control group was treated with bcnazepril hydrochloride tablets Exclusively. Urina microalbumin was detected in all patients 24 h before and after treatment. Results The effective rate was 94.7% and 86.8% in the treatment group and the control group respectively, showing significant difference (t= 9.31, P<0.01) . Conclusion The method of nourishing kidney, securing essence and cooling blood is effective to decrease urina microalbumin in incipient diabetic nephropathy.

Methods including stimulation, cauterization, of nuclei and measurement of pain threshold were used to clarify the role of paraventricular nucleus of hypothalamus (PVH) in pain regulation. Results showed that electrical or L-glutamate sodium stimulation of PVH could elevate the pain threshold in the rat dose-dependently, electrical cauterization of PVH could reduce the pain threshold; and removal of the pituitary gland could not influence the effect of L-glutamate sodium on pain threshold. These results suggest that PVH may play an important role in pain regulation.

Objective:To investigate the prognostic value of platelet volume indices (PVIs), neutrophil/lymphocyte ratio (NLR) and the combination of these parameters for the neurological function of acute ischemic stroke (AIS) patients after intravenous thrombolysis.Methods:From January 2016 to January 2019, the data of 147 AIS patients with intravenous thrombolysis in the Emergency Department of Peking University People's Hospital who met the diagnostic criteria of AIS were retrospectively analyzed. The patients were divided into two groups according to modified rank in scale (MRS) score: MRS≤2 and MRS≥3. The general information, past medical history and laboratory examination results of each group were compared. Logistic regression analysis was used to analyze the risk factors of poor prognosis of neurological function in AIS patients with thrombolysis.Results:NLR ( OR=1.045, 95% CI: 1.032-2.350, P=0.032), mean platelet volume (MPV) ( OR=4.212, 95% CI:1.074-16.513, P=0.039), MPV×NLR/PLT ( OR=5.711, 95% CI: 1.342-24.298, P=0.018), platelet distribution width (PDW) ( OR=1.015, 95% CI: 1.001-2.372, P=0.032), and NIHSS score ( OR=1.266, 95% CI: 1.111-1.443, P<0.01) were related with poor prognosis neurological function of AIS patients with intravenous thrombolysis. Conclusions:MPV, NLR, MPV×NLR/PLT PDW and NIHSS scores are the risk factors for poor prognosis of neurological function in AIS patients with thrombolysis. MPV×NLR/PLT can predict the neurological severity of AIS after 3 months.

Objective To explore the possibility of non-discarding blood after cisplatin hyperther-mic antiblastic perfusion(HAP)in treating the patients with malignant bone tumor of lower extremity.Methods Forty patients consisted of 31osteosarcomas and9malignant fibrous histiocytomas of bone.The clinical stages were wholly classified intoⅡB stage according to Ennekings surgical staging system for muscu-loskeletal tumors.The patients were divided into three groups:group1:discarding blood group(10cases),in whom200ml of the400ml blood remaining in heart-lung machine was discarded after HAP;group2:Non-discarding blood group(25cases),the blood remaining in heart-lung machine was not discarded after HAP and re-infused into systemic circulation;group3:systemic chemotherapy group(5cases),cisplatin was infused intravenously.The regional and the systemic blood cisplatin concentrations were determined at3,30and60minutes during HAP,and the systemic blood cisplatin concentrations were determined at0,0.5,1,2,4,8,12,24,48and72hours after HAP in the group1and group2.While1h after cisplatin infusion in-tra venously in the group3,the blood cisplatin concentration were also measured.Results The regional blood cis platin concen tra tions were high er than that in systemic blood at the time during HAP.The systemic blood cisplatin concen trations after HAP,ex cept at0minute in the group2were higher than that in the group1,there were sig nificant statistic differences between the two groups.The systemic blood cisplatin con-cen trations after HAP in the group2were simi lar to that after systemic chemotherapy.No severe adverse ef-fects in the group1were found.The Ennek ings surgical stagings for the tumors were turned fromⅡB intoⅡA in all the patients.Conclusion The method of non-discarding blood after HAP is available,it is not only local treatment ,but also systemic chemotherapy in the patients with malignant bone tumor of lower ex-tremi ty for limb-salvage surgery.

Objective To synthetically evaluate the relationship between miR-31 and the prognosis of carcinoma and to investi-gate its related mechanism.Methods The correlative literatures of tumor prognosis were retrieved from the electronic databases PubMed,EMBASE and ISI Web of Science.The pooled hazard ratios (HRs)and 95% confidence interval(95%CI )were extracted. The prognostic data were performed the synthesis analysis.Results A total of 7 trials conformed to the inclusion criteria including accumulated 2 012 cases of carcinoma.Meta-analysis revealed that the decrease of miR-31 expression in the tumor patients had the poor prognosis (HR=0.784,95%CI :0.630-0.974);in the subgroup analysis,the synthesis results adopting the multivariable a-nalysis and China subjects were 3.512 (95%CI :1.797-6.865)and 1.574 (95%CI :1.062-2.333),which indicating that the in-crease of miR-31 expression predicted the poor prognosis;miR-31 had no statistical significance in the digestive system (P >0.05). Conclusion The prognostic role of miR-31 may possess the histological and regional specificity and has the potential as a novel marker.
