At present,the doctor-patient relationship in China is a little tense,communication between doctors and patients is not smooth,and the doctor-patient communication skills of the young doctor is obviously insufficient and need to be improved.In this paper,we analyze the factors that affect the communication between doctors and patients in the Department of Neurology through the complexity of professional knowledge,the current background and so on.In addition,we discuss multiple methods of improving communication capability among this group doctors,hoping to strengthen young physicians' clinical basic skills training,and impart doctor-patient communication skills from the linguistic modifiers,oral expression,words and deeds,use of metaphor,simulation training and other aspects,and establish dynamic assessment system of doctor-patient communication ability.

Objective To investigate the effects of vitamin K1 in the adjuvant treatment of spasmodic cough in pertussis syndrome children,and its impacts on length of hospital stay.Methods 87 pertussis syndrome children were randomly divided into two groups,among which 41 cases in the control group were treated with the therapies such as anti -infection,respiratory support,antispasmodic,expectorant et al,while 46 cases in the treatment group were treated additionally with vitamin K1 on the basis of the control group.Then compared the duration and hospital stay of the two groups with spasmodic cough.Results The disappeared time of spasmodic cough in the treatment group was (7.22 ±1.33)d and hospital stay was (9.52 ±1.84)d,which in the control group were (15.51 ±2.73)d,(18.71 ± 3.30)d respectively,and there were statistically significant differences(t =-18.310,-16.269,all P <0.01).In the treatment group,the total effective rate was 93.5%,there were 18 cases with markedly effective,25 cases with effective and 3 cases with ineffective.Correspondingly,there were 7 cases markedly effective,23 cases effective, 11 cases ineffective,and total efficiency rate was only 73.1% in the control group,the difference was statistically significant(χ2 =4.285,P <0.05 ).Conclusion Vitamin K1 to alleviate spasmodic cough in children has a significant effect,which can reduce the duration of the cough time and hospital stay in pertussis syndrome children, and also can improve the clinical effect.

By reverse transcription-polymerase chain reaction (RT-PCR), an open reading frame of pathogenesis-related protein 1 (PR1) was isolated from Panax notoginseng and named as PnPR1. Molecular and bioinformatic analyses of PnPR1 revealed that an open reading frame of 501 bp was predicted to encode a 166-amino acid protein with a deduced molecular mass of 18.1 kD. Homology analysis showed that the deduced amino acid sequence of PR1 protein of Panax notoginseng had a high similarity with other higher plants had the same conservative structure domain of cysteine-rich secretory protein (CAP). The recombinant expressed plasmid pET28a(+)-PnPR1 was expressed in Escherichia coli BL21. The expression conditions were optimized by induction at different times, different temperatures, different IPTG concentrations and different giving times. The optimum expression condition was 0.4 mmol.L-1 IPTG at 28 degrees C for 20 h. The successful expression of PnPR1 provides some basis for protein purification and preparation of the monoclonal antibody.

AIM: To investigate multi-potential of rat bo ne marrow mesenchymal stem cells (rBMMSC) and mutation inclination, the rBMMSC w ere long passaged in vitro. METHODS: Cellular cycles of diff erent passages were assayed by FA CSan flow cytometry and karyotypes of passage 6, passage 25 and passage 45 were compared by G-binding analysis. RESULTS: The early passages and long-term passages all showed st rong proliferation; passage 6, passage 25 and passage 45 all showed normal karyo type. CONCLUSION: Long-term culture and passage of rBMMSC still remain s strong proliferation. With this capability, the mutation inclination is not enhanced.

AIM: To investigate the differentiation from adult rat and human bone marrow mesenchymal stem cells (BMMSCs) into neuron with musk polypeptide (Mu-P).METHODS: Adult rat and human BMMSCs were induced with Mu-P.Neuron-specific enolase (NSE),neurofilament (NF),Nestin,glial fibrillary acidic protein (GFAP) were detected by immunohistochemistry.RESULTS: Simple methods with Mu-P induced adult rat and human BMMSCs exhibiting a neuronal phenotype,expressing Nestin at 3 hours to 5 hours,and expressing NE and NF at 5 hours to 7 days.But the neuron-like cells didn't express the glial astrocyte marker GFAP.CONCLUSION: Adult rat and human BMMSCs can be induced to differentiate into neurons with Mu-P.

Objective To investigate the clinical symptoms and MRI imaging findings in patients with autoim-mune encephalitis and to improve clinician's understanding about the clinical and imaging characteristics of autoim-mune encephalitis. Methods We analyzed the clinical features and MRI findings of 33 patients with autoimmune en-cephalitis in our department. Results Of these 33 patients, 27 (81.8%) had psychiatric symptoms, 26 (78.8%) had seizure, 18 (54.5%) had involuntary movement, 11 (33.3%) had fever and 9 (27.3%) patients presented with cen-tral hypoventilation, the present of involuntary movement and fever was lower in group LE than in group NMDA. A total of 10 patients had positive MRI finding. Of these 10 patients, 8 had brain parenchyma lesions, 3 had meningeal involvement. The most likely affected parenchymal lesions are occipital lobe, bilateral hippocampus, frontal lobe, pari-etal lobe, temporal lobe, thalamus and cerebellum. Conclusion Psychiatric symptoms and seizure are the most com-mon neurological symptoms of autoimmune encephalitis. MRI may show abnormal signals in the limbic system. FLAIR is the most sensitive MR imaging sequence for detection of autoimmune encephalitis lesions.

Objective To explore the role of LiCl in modulating bacterial-mediated inflammation after Pseudomonas aeruginosa infection.Methods Western-blot was used to determine the efficacy of LiCl usage.The expression of inflammatory cytokines in Pseudomonas aeruginosa-infected macrophages and neutrophils was detected by qPCR.Cell apoptosis was measured by flow cytometry.Results Western-blot data showed that LiCl up-regulated the protein levels of p-GSK-3β(Ser 9)and β-catenin in macrophages and neutrophils,indicating the efficacy of LiCl usage.qPCR data indicated that LiCl enhanced the expression of anti-inflammatory cytokines and suppressed the expression of pro-inflammatory cytokines in Pseudomonas aeruginosa-infected macrophages and neutrophils.Flow cytometry data indicated that LiCl could promoted the apoptosis of Pseudomonas aeruginosa-infected macrophages and neutrophils.Conclusion LiCl inhibited the Pseudomonas aeruginosa-induced inflammation,via regulating the inflammatory cytokine expression and the apoptosis of inflammatory cells.
