ObjectiveTo investigate the clinical features and nursing care of neuralgic amyotrophy.MethodsThe course of the treatment and nursing in a group of patients with idiopathic neuralgic amyotrophy was analyzed retrospectively.ResultsMyoatrophy was found in all patients, while 42% of patients were involved in both sides. Serious pain, as initial symptom, was found in 92% of patients. After medical and physical treatment, as well as holistic nursing care, the pain disappeared in 1～2 weeks in all patients but one. All patients had been followed up for 2～13 months, muscle power was recovered in 67% of all patients, partially recovered in 33% of patients.ConclusionThe careful nursing and observation is very helpful for recover of neuralgic amyotrophy and can decrease complications.

At present surgical treatment is a main method for gastric cancer,while multidisciplinary comprehensive treatment for gastric cancer has gradually become the mainstream direction of treatment,which is based on regarding patients as the core part of treatment,aiming at specific disease,building multidisciplinary team and making individualized,standardized,scientific and continuous comprehensive treatment plan.Meanwhile,it can provide the best treatment option and efficacy for particular patients,and raise the diagnostic and treatment skills and academic level.There are obvious promotions in the integration between medical education and health management and the progresses of medicine and science.

Objective To evaluate the value of magnetic resonance black-blood thrombus imaging (BTI) of the stage of disease in intracranial venous and sinus thrombosis(CVT).Methods From June 2015 to October 2016,37 patients with CVT diagnosed with routine imaging examinations in Beijing Xuanwu Hospital,Capital Medical University were enrolled prospectively,and they also underwent BTI examination.The patients were randomly divided into either a acute group (≤14 d,n=23) or a chronic group (>15 d,n=14) according to the time from the onset of symptoms to BTI.Signal to noise ratio(SNR) and contrast to noise ratio(CNR) difference between acute and chronic CVT groups were compared.The magnetic resonance venography (MRV) examination was used as a reference to calculate the accuracy of BTI on per-segment level.Results (1) The SNR and CNR of thrombosis in the acute group and chronic group were 206±97 and 94±41,201±96 and 86±40,respectively.There was significant difference between two groups (t=4.9 and 5.0 respectively;all P<0.01).(2) In 37 patients with CVT,the thrombi in 159 cerebral veins and venous sinus segments were detected with MRV.BTI identified the thrombi accurately in 152 vascular segments,and the thrombi in 352 vascular segments were eliminated.The diagnostic sensitivity and specificity were 95.6% (152/159) and 98.0% (352/359) respectively.Conclusion Achieving direct angiography of cerebral venous thrombosis,BTI technique can accurately differentiate acute or chronic thrombus.It has higher accuracy.

Objective To investigate the immune response of IL-10 to Schistosoma japonicum infection in the early infectioin model and SEA immunization model of the IGTP~(-/-) and IRG-47~(-/-) mice.Methods In the early infection model,the IGTP knock out (IGTP~(-/-)) mice,IRG-47 knock out (IRG-47~(-/-)) mice and wild-type (WT) C57BL/6J mice were exposed to 300 S.japonicum cercariae via the pinna and sacrificed on day 7 post-infection.Each mouse pinna section was stained with hematoxylin-eosin (HE) to detect the pathological lesions,and the culture supernatant of pinna was used to test the levels of Th1/Th2 cytokines by indirect ELISA.In the SEA immunization model,IGTP~(-/-) IRG-47~(-/-) and WT mice were immunized with SEA twice and sacrificed in 3 weeks after the initial immunization.SEA-specific IgG antibody in sera was detected by indirect ELISA;the levels of Th1/Th2 cytokines were tested in culture supernatant of splenocytes by indirect ELISA;the proportions of CD4~+ T cells,CD8~+ T cells,B cells,Th1 and Th2 cells in the spleen were assayed by FACS.Results Although no obvious differences on the pathology of pinna were observed among the three mouse groups,the level of IL-10 in the culture supernatant of pinna of IRG-47~(-/-) mice was lower than that of IGTP~(-/-) mice in 7 days after the exposure.Following SEA immunization,the level of SEA-specific IgG antibody in sera of IGTP~(-/-) mice was lower than that in WT mice,the level of IL-10 in the culture supernatant of splenocytes of IRG-47~(-/-) mice was higher than that of IGTP~(-/-) and WT mice with the stimulation of SEA.However,the proportion of Th2 cells in the spleen of IRG47~(-/-) mice was the lowest among the three mouse groups.Conclusions SEA is the stimulus of IRG-47 deficiency mice to defend Schistosoma japanicum infection and promote the host to produce a protective response,and IL-10 may play an important role in immune regulation in this process.

OBJECTIVETo explore the effect of dexmedetomidine combined electrical stimulation on cognitive function of neurosurgical diseases patients treated by extracerebral intervention.

METHODSTotally 122 patients with neurosurgical diseases who underwent selective intervention were randomly assigned to the observation group and the control group, 61 cases in each group. Patients in the control group recieved anesthesia by dexmedetomidine. Those in the observation group received electrical stimulation at Baihui (DU20), Yintang ( EX-HN3), and Neiguan (PC6) before dexmedetomidine anesthesia. The cognitive function of patients at preoperative day 1 and postoperative day 1 was respectively evaluated by Mini-Mental State Examinations (MMSE). Serum NSE, S-100β, IL-1β, IL-6, and TNF-α levels were detected in the two groups before intervention and immediately after intervention using ELISA.

RESULTSMMSE scores of two groups were significantly reduced at post-intervention day 1, as compared with one day before intervention. MMSE score of the observation group at post-intervention day 1 was (23.15 ± 1.87) points, significantly higher than that of the control group [ (19.34 ± 1.64) points , (P < 0.05)]. The postoperative cognitive dysfunction (POCD) incidence rate of the observation group was 16.4% (10/61), significantly lower than that of the control group [39.3% (24/61); P < 0.05]. Compared with before intervention, NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels of the two groups increased (P < 0.05). Post-intervention NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels were significantly lower in the observation group than in the control group (P < 0.05).

CONCLUSIONDexmedetomidine combied electrical stimulation could effectively prevent the occurrence of postoperative cognition, and reduce levels of NSA, S-100β, IL-1β, IL-6 and TNF-α.

Objective Precondition is an approach to myocardial protection during ischemia-reper-fusion by inhibiting myocardial cell apoptosis.The purpose of this study was to evaluate the cardioprotective effect using 99Tcm-syuaptotagmin I (Syt I)-C2A to detect myocardial cell apoptosis in the myocardial is-chemia-repedusion rat model.Methods (1) The C2A domain of Syt I was labeled with 99Tcm using 2-iminothiophene hydrochloride (IT) method.Radiochemical purity was determined with thin layer chroma-tography.The binding activity of radiolabeled protein was assessed using eamptothecin-treated Jurket cells.(2) One group of 6 rats was prepared for myocardial ischemia-reperfusion model(A group),and another group of 6 rats was prepared for myocardial ischemia precondition model(B group).99Tcm-Syt I-C2A was injected via the tail vein at a dosage of about 7.4 MBq.At 1h after injection,the rat was sacrificed,and the heart was removed to rinse with saline and dye with triphenyl tetrazolium eoride (TTC).According to the resdt of myocardial dye,theischemic myoeardium was separated from the viable myocardium and weight was measured,and then its radioactivity was determined by gamma counting.The difference of radioactive uptake in the ischemic myocardium between these two group models was compared using percentage activity of injection dose per gram of tissue(%ID/g)±standard deviation(x±s).SPSS 12.0 was used for data analy-sis,and t-test was used to compare data.Results (1) The radiochemical purity of 99Tcm-Syt I-C2A was (98.90±0.43)%,and the radioactivity in the camptothecin-treated group was (10.99±0.55) folds higher than that of non-treated viable control group.(2)In the ischemia-reperfusion model,the radioactive uptake of 99Tcm-Syt,I-C2A was(2.41±0.32)%ID/g in the ischemic myocardium,and(0.16±O.02)%ID/g in the nomud myocardiunm.However,in the myocardial ischemia precondition model,(0.46±0.05)%ID/g in the isehemic myocardium was measured,and(0.20±0.05)%ID/g in the normal myocardium.Uptake of 99Tcm-Syt I-C2A in ischemic myocrdium showed statistically significant difference (t=8.52,P
