Limb-shaking transient ischemic attack (TIA), a rare manifestation, is commonly caused by severe stenosis or occlusion of an extracranial internal carotid artery. Such patients are usually treated with surgical revascularization or anti-platelet therapy. We present a 56-year-old woman with 6 months’ episodic attacks starting with mouth skewed to the right and a sensation of ‘weakness’ involving predominantly her left arm, and at times, also involved the left leg. This was immediately followed by rhythmic jerky movements of the left arm and at times, also involved the left leg. Magnetic resonance angiography revealed severe stenosis of M1 segment of the right middle cerebral artery. The patient’s symptoms were signifi cantly improved by treatment with anti-platelet drugs and nimodipine.

ObjectiveTo investigate the effects of nasal continuous positive airway pressure (nCPAP) and intubation in very low birth weight preterm infants. Methods One hundred and twenty-three very low birth weight preterm infants with respiratory distress within 60 minutes after birth were randomly assigned to nCPAP (n=63) or intubation group (n=60).Outcomes at 7,28 days and 36 corrected gestational weeks were assessed with x2 or t-test. ResultsThere were no significant difference in fatality rate and incidence of bronchopulmonary dysplasia between nCPAP group and intubation group [7.9％ (5/63) vs 6.6％(4/60),4.8％(3/63) vs 3.3％(2/60),x2 =0.07and 0.16,P＞0.05].In nCPAP group,the use of pulmonary sulfactant was 27.0％ (17/63),lower than that (83.3 ％,50/60) in intubation group (x2 =39.34,OR=0.3,90 ％ CI:0.2-0.6,P＜0.05) ;The nCPAP group had fewer ventilation support in 28 days [17.5％ (11/63) vs 25.0％ (15/60),OR=0.7,90％ CI:0.4-1.4] and 36 weeks [6.3％ (4/63) vs 8.3％ (5/60),OR=0.8,90％ CI:0.2-2.4] than those in intubation group but without statistical difference (x2=1.05 and 0.01,P＞0.05,respectively).The incidence of air leak in nCPAP group were lower than intubation group [11.1％ (7/63) vs 33.3％ (20/60),x2 =8.86,OR=0.3,90％00 CI:0.2-0.7,P＜0.05].There was no significant difference for other complications between two groups. ConclusionsIn very low birth weight preterm infants,early nCPAP dose not significantly reduce the fatality rate and the incidence of bronchopulmonary dysplasia as compared with intubation ventilation,but shorten the time of ventilation and lower the incidence of air leak.

ObjectiveTo observe production of vascular endothelial growth factor (VEGF) induced by granulocyte/macrophage colony-stimulating factor (GMCSF)via ERK nerve growth factor (NF)-κB singling pathway in human fibroblasts during wound healing and explore relating mechanism.MethodsHuman fibroblasts from the injured skin were used for this study and treated with GMCSF.RT-PCR was used for analyzing the protein and mRNA levels of VEGF and Western blotting was employed to determine the phosphorylation of ERK. The fibroblasts were pre-treated with ERK specific inhibitor PD98059 and further treated with GMCSF, then the fibroblasts and the supernatant were collected for detection of protein level of VEGF by means of Western blot. ERK signal pathway was inhibited to detect the activation of NF-κB by means of immunofluorescence staining. Furthermore, the nuclear and cytoplasmic extraction kit was used to separate the cytoplasm and nucleus and Western blot employed for observation of the NF-κB activation. ResultsThe mRNA level and protein level of VEGF were increased significantly with treatment with higher concentration of GMCSF in a dose-dependent manner. VEGF mRNA level was increased two hours after administration with GMCSF and reached peak at 4-6 hours. GMCSF could remarkably activate the ERK phosphorylation. Compared with GMCSF, the ERK specific inhibitor PD98059inhibited significantly the effect of GMCSF in inducing VEGF expression (P ＜ 0.05). Western blot and immunofluorescence staining analyses showed that the activation of NF-ΚB was inhibited with reduced production of VEGF after GMCSF treatment.Conclusion GMCSF up-regulates production of VEGF through activating NF-κB via ERK signal pathway in the human fibroblasts.

OBJECTIVETo observe the clinical efficacy and safety of Corydalis composite (CDC) combined with methotrexate (MTX) in treating rheumatoid arthritis (RA).

METHODSSeventy-six RA patients were randomly assigned to 2 groups, 37 in the treated group received the combined therapy, and the 39 received MTX treatment alone, all were treated for 12 weeks. Efficacy of treatment was evaluated adopting the standard of American College of Rheumatology (ACR), taking ACR20 as the chief criterion; ACR50, ACR70 as well as the clinical indexes and items in Health Account Questionnaire (HAQ) as the auxiliary criteria, including joint swelling index, joint tenderness index, holding power, morning stiffness time, resting pain, erythrocyte sedimentation rate (ESR), C-reactive protein. And the adverse reaction was recorded at the same time.

RESULTSAfter being treated for 4, 8 and 12 weeks, the ACR20 response rate reached 35.14%, 59.46% and 70.27% respectively in patients of the treated group, while that in the control group was 17.95%, 35.90% and 46.15% respectively, significant difference between groups was shown in the outcome of week 8 and 12 (P < 0.05). ACR50 and ACR70 improving rate at all the time points of observation were increased in the treated group, with the ACR50 improving rate at week 12 higher than that in the control group (43.24% vs. 20.51%, P < 0.05). As compared with the control group, the improvements in all the auxiliary criteria were more significant in the treated group (P < 0.05). The incidence of adverse reaction was less in the treated group than in the control group (32.43% vs. 56.41%, P < 0.05), particularly in term of the damage on liver (0 vs. 10.26%, P < 0.05).

CONCLUSIONCDC combined with MTX is more effective than MTX alone in treating active RA with less adverse reaction.

Objective To explore the clinical characteristics of neonatal dengue fever. Methods The clinical data from 4 neonates with dengue fever who were admitted and treated in 2014 were retrospectively analyzed and the related literatures had been reviewed. Results Four cases of neonatal dengue fever were all males. Three cases were mother to child transmission, the age at onset was 1 to 7 days after birth, and their mothers suffered with prenatal fever and were diagnozed of dengue fever during perinatal period. One case was community acquired, the age at onset was day 21 after birth and the neonate was bit by mosquito the day before. All four neonates had fever, two cases had rash, and one case had hemorrhagic spot. None of them had jaundice or cough. All of them had thrombocytopenia ( 30-125 )× 109/L, prolonged activated partial thromboplastin time ( 44 . 0-89 . 8 s), and increased aspartate aminotransferase (AST) ( 46-71 U/L). Three cases had declined ifbrinogen ( 1 . 36-2 . 53 g/L). Two cases had increased CK-MB ( 29-86 U/L). Two cases had increased CRP ( 3 . 00-46 . 05 mg/L). After the treatment of anti-infection and intravenous immunoglobulin, all of them were cured and discharged. The duration of hospital stay was 4-17 days. Conclusion The clinical manifestations of neonatal dengue fever were mainly fever and blood coagulation dysfunction, clinical symptoms are mild and lack of speciifcity, and prognosis are good. Mother to child transmission is one of the ways of dengue virus infection.

ObjectiveTo develop a new sutureless technique (photochemical tissue bonding,PTB ) for repair of corneal perforation. Methods A total of 60 rabbits were used for creating corneal perforation models.The corneal perforation on the left eye was repaired by sutures and the injury on the right eye was fixed with the use of amniotic membrane with PTB.The outcomes of the two mentioned repair methods were compared by observing the leakage of aqueous and the morphology of the anterior chamber at different instants,measuring the intraocular pressure (IOP) and observing the formation of neo-vessels and scars of cornea in the use of histological analysis. Results There was no leakage of aqueous and no difference for morphology evaluation in both treatments.PTB could adhere AM on the cornea to restore the corneal perforation.The peak IOP in the PTB treatment group at days 0,7 and 14 postoperative [ (531.2 ±49.5) mm Hg,(542.6 ±74.8) mm Hg and (603.9 ±69.1) mm Hg,respectively] was significantly higher than that in the suture group at the same instants [ (41.3 ±12.7) mm Hg,(142.6 ±25.4) mm Hg and (333.3 ± 66.7) mm Hg,respectively] (P ＜0.O1 ).Compared with suture repair,the treatment with PTB resulted in a better outcome of wound healing with less neo-vessels and less scars of cornea. Conclusion PTB treatment for repair of corneal perforation is superior to suture repair.

ObjectiveTo investigate the relation of the human cytomegalovirus pp67-mRNA with　the active infection in renal transplant recipients and the role in the direction for antiviral therapy.Methods　Total 128 samples were collected from peripheral blood treated with EDTA of 32 recipients at the 3rd week　or the 7th week after transplantation.IFA was used to detect CMV pp65 antigen,and NASBA was used to　detect pp67 mRNA assay.Compared with CMV-Ag,the recipients were followed up to observe the change of　pp67 in the cases of the active infection and the CMV disease.ResultsCompared with the proportion between two groups,44 samples out of 128 samples showed CMV-Ag pp65 positive,while pp67-mRNA were　positive in 21 samples.8 patients had been found positive CMV-Ag pp65 and pp67-mRNA; 12 recipients　were clinically diagnosed with HCMV disease.In the early stage of the HCMV infection,the sensitivity and　specificity of the CMV-Ag pp65 ( 91.7％,50.0％ ) was higher than that of pp67-mRNA ( 66.7％,95.0％ ).During the periods of symptoms appeared and the late stage of clinical treatment,the specificity　of pp67-mRNA was higher than that of CMV-Ag pp65,while the sensitivity sit on the contrary.And in the　antiviral therapy course,the indicator of antiviral therapy pp67 turned negative more quickly than the CMVAg,the therapy course could be reduced.ConclusionsBoth of CMV-Ag pp65 and of pp67-mRNA have　clinical significance.Testing for CMV-Ag pp65 is suitable for detecting HCMV active infection at the early　stage,which was important for in time anti-virus treatment in the clinical settings.The test for pp67-mRNA　is a quick method to accquire the accurate results; therefore,it can be used as the reference criteria for the　clinical anti-virus treatment.
