Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune syndrome of central nervous system.The main clinical manifestations include psychiatric symptoms,movement disorders and seizures.It is often misdiagnosed as viral encephalitis.Tumors,especially the ovarian teratoma,play an important role in the disease.The prevalence in children is beyond imagination.Anti-NMDAR antibodies are specific diagnostic tests.Immune suppression is the main treatment.The first-line treatments include corticosteroids,intravenous immunoglobulin,and plasmapheresis.The second-line treatments include biological agents and cytotoxic drugs.Early diagnosis and treatment are essential for neurologic recovery.Overall prognosis is good.

Objective To investigate the effect of Tongxinluo capsule combined with metoprolol on elderly patients with coronary heart disease and angina pectoris and its influence on hemorheology and inflammatory factors.Methods 135 elderly patients with angina pectoris of coronary heart disease were selected,and they were randomly divided into treatment group (68 cases) and control group (67 cases).The treatment group was treated with Tongxinluo capsule combined with metoprolol,while the control group was treated with metoprolol.The two groups were treated for 8 weeks.The curative effect of the two groups was compared,the number and duration of angina pectoris,the changes of hemorheology and inflammatory factors before and after treatment were compared.Results The total effective rate of the treatment group (94.12％) was higher than 76.12％ of the control group (P ＜ 0.05).After treatment,the frequency and duration of angina pectoris in the treatment group were (6.03 ± 1.21) times/week and (3.02 ± 0.76) min/time,respectively,which were significantly lower than those in the control group [(9.87 ± 1.46) times/week and (4.86 ± 0.98) min/time] (t =16.649,12.201,all P ＜ 0.05).After treatment,the whole blood viscosity at high shear rate [(3.76 ± 0.41) mPa/s],whole blood viscosity in low shear [(8.13 ± 0.76) mPa/s],plasma viscosity [(1.23 ± 0.08) mPa/s],erythrocyte aggregation index [(2.06 ± 0.27)],fibrinogen [(2.46 ± 0.41) g/L] in the treatment group were lower than those in the control group[(4.53 ± 0.52) mPa/s,(9.61 ± 0.89) mPa/s,(2.09 ± 0.27) mPa/s,(2.63 ± 0.35),(3.53 ± 0.62) g/L] (t =9.562,10.396,25.170,10.604,11.844,all P ＜ 0.05).After treatment,the interleukin-6 (IL-6) [(8.49 ± 1.76) pg/mL],intercellular adhesion molecule-1 (ICAM-1)[(85.25 ± 8.92) pg/mL],C reactive protein (CRP) [(8.74 ± 1.76) mg/L] in the treatment group were lower than those in the control group[IL-6 (11.32 ± 2.10) pg/mL,ICAM-1 (103.42 ± 10.72) pg/mL,CRP (14.98 ± 2.24)mg/L] (t =8.491,10.712,18.012,all P＜0.05).Conclusion Tongxinluo capsule combined with metoprolol in the treatment of elderly patients with coronary heart disease angina pectoris has obvious curative effect,and can improve the patients'blood rheology and inflammatory reaction.

ObjectiveTo investigate the relationship between carotid atherosclerosis and progressing stroke.Methods103 patients with acute cerebral infarction within the first 24 hours from onset were tested with carotid color doppler ultrasonography during the first week from admission. Univariate and multiple logistic regression analyses were performed to examine the relationship between carotid intima media thickness (IMT), plaque structure, the degree of artery stenosis and the early deterioration of cerebral infarction.ResultsPrevalence of carotid plaque and thickness of IMT in patients with progressing stroke were higher than that in non progressing patients. In logistic regression, presence of carotid plaque was independent predictors of progressing stroke. Plaque size, extent of artery stenosis and IMT were not included in the regression model.ConclusionPlaque structure and its chemical feature may be the cause of progressing stroke.

Objective To classify all the plant pollen allergens, each allergen sequence available was compared with protein family database. After that, the appearance and taxonomic distribution of each protein family could be known. When made reference to evolutionary analysis, a regular rule of the distribu-tion of all plant pollen allergens could be concluded. Methods Protein family memberships of each allergen were assigned by comparing the sequences with the Pfam database. Representative members of the most a-bundant pollen allergen families were compared with the Uniprot database using the BLAST server. Acces-sion number of all the interesting homologous could be obtained and all the sequence information could be ac-quired by Batch Entrez. Finally, the evolutionary trees were drawn with the help of MEGA4.0 software. Re-sults One hundred and sixty-eight pollen allergens were classified into 26 protein families. Profilins, pollen _allerg_1 and EF hands constituted the most abundant pollen allergen families. Profilins and EF hands oc-curred in almost all allergenic plant families, whereas allergenic Expansins, FAD_binding proteins, Amb_V allergens and Thaumatins were confined to single taxon. Conclusion It is concluded that the highly con-served sequences of allergens families such as Profilin may be one of the most important reasons of the cross reactivities in allergic diseases. The classification of pollen allergens may be helpful to clinical practice and basic research.

Objevtive To evaluate the efficacy and safety of intensive pulse light (IPL) on treating the telangiectasis and dermal atrophy due to corticosteroid-dependent dermatitis.Methods We applied the IPL on 13 patients who had telangiectasis and dermal atrophy caused by corticosteroid-dependent dermatitis every three to four weeks.The treatment lasted three to eight times.The patients's skin types were Fitzpatrick Ⅲ-V and they had had corticosteroid therapy from 15 months to 13 years.Results To telangiectasis,3 patients had excellent effect afterwards;7 patients achieved fair good effect;Another patients also achieved improvement;2 cases had no positive effect;The total effective rate reached 76.92%.10 patients of dermal atrophy among the total 13 had improvement of the thickness of dermis.Conclusion Intensive pulse light can improve the telangiectasis and dermal atrophy of corticosteroid-dependent dermatitis.It needs less recovery time with fewer side effects and therefore IPL is an effective method for the Iesions.

MicroRNA(miRNA)is a kind of 22 nt endogenous small non-coding single strand RNA and is universally present in animals and plants.It can suppress the expression of target genes at post-transcription al level by complementary biding to the 3'UTR of target mRNAs.Recent studies indicate that microRNA is closely associated with tumorigenesis,differentiation,metastasis and relapse.MicroRNA might act as a new biomarker of tumor diagnosis and a new target of tumor gene therapy.

Transient ischemic attack (TIA) is an independent risk factor of stroke. About two-thirds patients with TIA will reoccur TIA or stroke. To predict the risk of stroke after the onset of TIA may identify the prognosis of patients, so as to have an intervention for the high-risk patients as early as possible. This article reviews the various risk assessment tools for stroke after TIA, in order to provide ideas for the prognostic assessment of TIA.

Objective To probe into the related factors and nursing of nosocomial infection for infectious diseases ward. Methods 2198 cases of patients in infectious diseases ward of our hospital were selected from February 2008 to December 2009, prospective monitoring and retrospective analysis were simultaneously adopted. Results In cases of nosocomial infection, mainly respiratory tract was the infection site, where the upper respiratory tract infection rate was 30.52%, lower respiratory tract infection rate was 28.57%, higher than other parts, there were significant differences. At the same time, nosocomial infection due to indwelling catheter and the irrational use of antibiotics led to higher rates of infection, 19.23%and 17.69%, there were significant differences. In addition, we could see from the age of nosocomial infection, ≤ 3-year-old children and elderly patients ≥ 60 years old had higher infection rate, 9.43% and 9.71%, there were significant differences. Conclusions According to elements features of infectious disease outbreak in hospital ward, to take effective care and prevention measures to reduce the infectious diseases room of the hospital infection will be of great clinical significance.

Objective To discuss the matrix metalloproteinase ( MMP- 13 ) and insulin-like growth factor (IGF)-1 in knee osteoarthritis (OA) and Kashin-Beck disease (KBD) and to explore the mechanism of synovial lesions and their similarities and differences are compared. Methods Synovial fluid of 18 OA patients, 13 KBD patients, 6 normal controls were collected and their synovium were obtained at the same time.The synovium MMP-13 and IGF-1 were examined by immunohistochemistry, while those of the synovial fluid were tested by enzyme-linked immunosorbent assay (ELISA). One way ANOVA and LSD-t test were used for statistical analysis. Results The results of these 37 synovial tissue and synovial fluid samples showed that: ① The average optical density of the positive staining of the KBD synovial tissue (692±131,354±101, 415±62) was not statistically significant from that of the OA group (452±57, 366±65, 652±86)(P＞0.05) and the control group (541±98, 524±202, 379±94, P＜0.05). ②There was significant different between the expression of IGF-1 of synovial tissue in the KBD group (311±174, 235±95, 412±109) and the OA group (452±57, 652±75, 544±64) as well as the control group (251±29, 336±54, 388±76)(P＜0.05).③ Compared with the concentration of MMP-13 in the synovial fluid of the OA group (0.93±0.51), there was no significant difference between the OA and the KBD group (2.02±1.12) (P＞0.05); but, there was significant differences when compared with the control group (2.33 ±0.29, P＜0.05). ④ When compared the the concentration of IGF-1 in the synovial fluid in the KBD group [ (2.87±1.48) and the OA group (1.27±0.33)as well as that of the eontrol group (0.93±1.07)] the difference was significant. Conclusions ① Cartilagedegeneration and joint damage may be a part of the articular synovial lesions in KBD patients, just like that of the OA, and the may exist as a part of the pathogenesis. ② MMP-13 may be involved in the synovial damage,and is the major degenerating factors in cartilage extracellular matrix (ECM) in OA patients and KBD patients. ③ As one of the ECM synthesis factors, IGF-1 may play an important role in the synovial damage of OA and KBD disease, but the repair mechanism may be different between the two diseases.
