Objective To determine the diagnostic value of antifilaggrin antibodies(AFA) in rheumatoid arthritis(RA) and to compare the correlation among AFA,anti-perinuclear factor(APF) and anti-keratin antibodies(AKA). Methods Filaggrin was extracted from human epidermis and then partially purified. AFA in 103 cases of RA and 140 cases of controls were detected by western blot. APF and AKA were detected using indirect immunofluorescence. Results AFA test resulted in diagnosis of 35.9% of 103 RA samples, with a specificity of 93.7%. The result was significantly higher than the controls (P

Objective To retrospectively analyze the result of hemoglobin(Hb)test by using full-automatic Hb electrophoresis and evaluate the its significance in hemoglobinopathy.Methods The data of patients who underwent Hb electrophoresis test and regular blood tests in the hospital from January 2011 to December 2013 were included in the study.The test results were recorded including mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH)and results of Hb electrophoresis test.Final diag-nosis were made for suspected patients by using genetic testing,then disease detection rates and gene coincidence rates and constitu-ent ratios were calculated.Results 12 898 cases were included in the study,after statistical analysis the MCV was(85.32±13.61) fL,MCH was(29.87±6.44)pg.By using automatic hemoglobin electrophoresis,1 315 cases were found to be positive,in which 568 were male,747 were female,the detection rate was 10.19%.In the 1 315 patients,there were 761 cases suspectedα-thalassemia,ac-counted for 5.90%.There were 495 cases of suspectedβ-thalassemia,accounted for 3.84%,11 patients with HbJ(0.08%),15 pa-tients with HbK(0.12%),9 patients with HbG(0.07%),3 patients with HbD(0.02%),21 patients with HbE(0.16%).The sus-pected case′s final diagnosis were made by using genetic testing,α-thalassemia gene′s coincidence rate was 80.55%,β-thalassemia gene′s coincidence rate was 96.77%.Conclusion Automatic hemoglobin electrophoresis detection is of great significance for the di-agnosis of hemoglobinopathy.

ObjectiveTo analyze the clinical characteristics of systemic lupus erythematosus (SLE) patients with cerebral tuberculosis.MethodsTen SLE patients with cerebral tuberculosis admitted to Peking Union Medical College Hospital(PUMCH) from January 1995 to October 2010 were retrospectively analyzed.ResultsThe median duration from onset of SLE to cerebral tuberculosis was 1.5 years(range from 0.6 to 30 years).All patients had received higher doses of steroid therapy (equal to prednisolone l mg· kg-1·d-1 ),and 3 of them had received methylprednisolone pulse therapy.Nine patients had taken immunosuppressant.When cerebral tuberculosis was diagnosed,the most common features were fever and headache,followed by nausea/vomiting and focal neurological signs.Nine patients were complicated with extra-cerebral infections.The cerebrospinal fluid(CSF) pressures was(247±66) cm H2O(range from 180 to 350 cm H2O),which was higher than normal.The mean CSF protein level was(1.4±0.7) g/L (0.15～0.45 g/L),which was normal or increased.Image examinations were helpful for the diagnosis of cerebral tuberculosis in SLE patients.Pointenhanced or ring-enhanced lesions were found in enhanced magnetic resonance imaging( MRI ) of brain in all patients who had donethis test (8 patients).After treated with targeted antibiotics and specific adjuvant therapies,the symptoms had relieved in 7 patients,however,I patient died,and 2 patients were lost during the follow-up.ConclusionWhen SLE patients with stable disease have unexplained fever,headache,and focal neurological signs,cerebral tuberculosis should be considered.Enhanced MRI of brain and chest X ray are helpful for the diagnosis of infectious cerebral lesions and should be performed promptly.Extracerebral tuberculosis infections can provide clues forthe identification of the causativeagents.Anti-tuberculosis treatment should be initiated as soon as the diagnosis is confirmed,and early treatment can markedly improve the outcomes.

Objective To study the effects of protein kinase A (PKA) phosphorylation site' s mutation of mitofusin-2 (Mfn2) on intimal proliferation after balloon injury of carotid artery of rats. Method Rat model of carotid artery balloon injury was established and infected with Adv-LacZ, Adv-Mfn2, AdvMfn2-S442A or Adv-Mfn2-S442D from the peri-arterial sheathes of vessels, while phosphate buffered solution (PBS) used instead of above infectious adenovirus as uninfected group and sham operation as control group. The rats were sacrificed 14 days after balloon injury of carotid artery in order to measure the level of Mfn2 protein and the prol9iferation cell nuclear antigen (PCNA) with immunohistochemistry staining. The morphology of vessels was observed with HE staining. All data were statistically analyzed with ANOVA and Dunnett-t test. Results Fourteen days after surgery, the levels of Mfn2 protein significantly increased in arteries infected with Adv-Mfn2, Adv-Mfn2-S4442A and Adv-Mfn2-S442D compared with those in control group, sham operation group and Adv-LacZ infected group. The ratio of intimal area/medial area (I/M) and percentage of PCNA positive cells in both Adv-Mfn2 and Adv-Mfn2-S442A groups markedly decreased compared with control group (P ＜0. 01 ) . Compared with the Adv-Mfn2 group, the I/M and the percentage of PCNA positive cells reduced more significantly in Adv-S442A group (P ＜ 0. 01 ) . However,the I/M and the percentage of PCNA positive cells in Adv-LacZ and Adv-S442D groups were not significantly different from those found in the control group. Conclusions The over-expression of Mfn2 gene may effectively inhibit intimal proliferation after balloon injury of carotid artery of rats. The inhibitory effects of Mfn2-S442A are more obvious than those of Mfn2. However, the Mfn2-S442D is out of the inhibitory effect on neo-intimal proliferation.

Objective To explore the effect of clinical nursing path (CNP) on stroke patients. Methods 80 stroke patients were divided into control group and experimental group with 40 cases in each group. The control group received functional nursing, while the experimental group received care in accordance with the design of CNP map. Results The mastery rate of health knowledge and the satisfaction rate were higher, and the hospitalization time was shorter in the experimental group than in the control group (P<0.05). Conclusion The implementation of CNP could increase the mastery degree of health knowledge, improve the satisfaction rate of patients for nursing service, and shorten the hospitalization time.

ObjectiveTo observe the outcomes of psychological nursing for earthquake patients in recovery stage. Methods90 earthquake patients were divided into 4 groups by age and accepted psychological nursing. They were evaluated for post-traumatic stress disorder (PTSD) a year after earthquake. ResultsNone PTSD had been found. ConclusionPsychological nursing can improve self-care ability and confidence of the earthquake patients.

Results and ConclusionThe age (OR=1.016), renal failure (OR=4.648), lower limb fractures (OR=2.404), spine fracture (OR=3.558), right hand fractures (OR=1.190), right foot fractures (OR=4.389) and the complex fractures (OR=2.600) were associated with the poor ADL (<60). The rehabilitation nursing for fracture were reported and discussed.

0.05),Conclusion The possibihty of thymoma should be considered among those late-onset SLE patients.The glucocorticoid-based immunosuppressive therapy is effective for thymoma-associated SLE.To treat SLE is not an indication for thymectomy.

Objective To standardize the operation processes of neonatal instrument,ensure the standards effectiveness and safety of equipment use.Methods A retrospective study had been taken on after the developments and implementations of all neonatal instruments standard operation procedure (SOP).The equipment maintenance data were collected and analyzed one year before and after the implementation of SOP.Results After the effective implementation of the SOP,the incidence of instrument repair due to misoperation,improper maintenance reduad by 59％(19/32),9/14,4/7,the instrument management efficiency was enhanced,and the safety of nurses and patients was guaranteed,and the patients satisfaction was improved,and also the quality of care was enhanced.Conclusions SOP procedure plays a very important role in improving neonatal care management and overall efficiency.It makes a continuous improvement of nursing care which is worth widely being implemented.
