Narcolepsy is a rare sleep-wake rhythm disorder in clinic practice, mainly characterized by recu-rrent unstoppable sleep during the day and often accompanied by cataplexy, sleep paralysis and hypnagogic hallucinations.Clinicians′ insufficient knowledge about narcolepsy is one of the main causes of misdiagnosis and delayed diagnosis.Moreover, narcolepsy may get easily confused by epilepsy because of complex and diverse types of epileptic seizures.Therefore, it is necessary to distinguish the two forms each other.When they are comorbidity, the diagnosis and treatment will be much more difficult.In this article, the clinical characteristics of narcolepsy and the causes of delayed diagnosis were analyzed, differential diagnosis between narcolepsy and epilepsy was investigated, and practical expe-rience in diagnosis and treatment of comorbidities were summarized, so as to raise clinicians′ awareness of narcolepsy and its comorbidity with epilepsy and improve patients′ prognosis and their quality of life.

This paper was aimed to study the genetic diversity and genetic relationship of germplasm resource of Lonicerae Japonicae Flos in order to provide references for its breeding. A total of 36 samples from 18 farm varieties and wild species, as well as related species of Lonicera japonica Thunb. from the main production areas were studied by ISSR-PCR markers. The Jaccard coefficient was worked out by NTSYS-pc software. And a cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic mean (UPGMA). The re-sults showed that 12 ISSR primers generated 129 loci of which 114 loci were polymorphic. The average percentage of polymorphic bands (PPB) is 88.37%. In the cluster dendrogram, different samples of Lonicera japonica are in the same group, which showed that it is a natural species; the wild sample is separated from the cultivated samples; the traditional type-Maohua is relative stable, but the type of Jizhuahua includes complicated varieties, and it has obvi-ous genetic variation; the new variety Jiufeng 1 has already distinct into one stable type. It was concluded that the ISSR method was suitable for germplasm identification, genetic diversity analysis of Lonicerae Japonicae Flos, thus providing a theoretical foundation for its cultivation and breeding.

Objective To observe the influence of local-anaesthetic combined with dezocine on brachial plexus block and postoperative analgesia.Methods 60 patients scheduled for unilateral upper limb operation were randomly divided into two groups of C group and D group with 30 cases in each group.The brachial plexus block was performed under ultrasound guiding.Two groups received a bolus injection of local anesthetic 30ml,but the local bolus injection of D group consisted of Dezocine 10mg.The tine of sensory blocked producing effect,anesthesia effect,sensory blocked duration were observed.Two hours after sensory nerve recovered,the scores of VAS pain and Ramsay Sedation were recorded.Adverse reactions of perioperation were also observed(nausea,vomiting,dizzy,respiratory,urine retention,pruritus).Results The sensory blocked duration in D group was(7.1±1.1)h,which was significantly longer than that of C group[(4.5±0.8)h](t=10.47,P＜0.01);Two hours after sensory nerve recovered,the score of VAS pain in D group was(1.7±0.7)points,and significantly lower than that of C group[(3.9±1.0)points](t=9.87,P＜0.01).Both two groups had no adverse reactions.Conclusion Addition dezocine 10mg to local anesthetic solutions for interscalene brachial plexus block,it could prolong the sensory block duration,provide satisfactory postoperative analgesia,have no adverse reactions.

Objective · To observe effect of 17β estrodial (17β E2) with different concentrations on C type natriuretic peptide (CNP), insulin like growth factor 1 (IGF1), and natriuretic peptide receptor B (NPR-B) expression and proliferation of growth plate chondrocytes of rats in vitro. Methods · Eight Wistar rats were sacrificed and their epiphyseal cartilages of the upper tibias were separated to obtain chondrocytes on the 14th day after birth. Then chondrocytes were cultured with 17β E2 in different concentrations (10-4、10-6、10-8、10-10 and 10-12 mol/L) for 48 h, while control group was cultured without 17β E2. CCK8 method, ELISA and qRT-PCR were used to analyze the proliferation of chondrocytes, the levels of CNP and IGF1 in culture medium and mRNA levels of CNP, NPR-B and IGF1, respectively. Results · 17β E2 in different concentrations affected the proliferation of growth plate chondrocytes significantly. When the concentration of 17β E2 was 10-8 mol/L, it had the strongest effect on the cell proliferation. When the concentration increased to 10-4 mol/L, the proliferation of chondrocytes was inhibited. With the increasement of 17β E2 concentration, the levels of CNP in the culture medium and the mRNA levels of CNP in the chondrocytes were significantly different. The highest levels of CNP protein and mRNA both appeared in 10-8 mol/L group, while the lowest levels both appeared in 10-4 mol/L group. IGF1 and its mRNA also reached the highest levels in 10-8 mol/L group,but the lowest concentration and mRNA level were in 10-10 mol/L group and 10-12 mol/L, respectively. Both CNP mRNA and protein levels were positive correlated with the proliferation of chondrocytes (P=0.000). Nevertheless, there was no significant correlation between the proliferation of chondrocytes and IGF1 mRNA or protein levels (P>0.05). Conclusion · 17β E2 modulates proliferation of rat growth plate chondrocytes in a dose-effect manner. It enhances proliferation at relatively low concentrations (10-10-10-8 mol/L) and inhibits proliferation at high concentration. This effect is positively related to CNP expression in chondrocytes.

Viable but non-culturable state in bacterial cells as received uncultured microorganism has be- come the fundamental research issues in medical microbiology, epidemiology, general microbial ecology and sanitation quarantine since it was put forward in 1982. When in this state, bacterium are no longer able to grow and form colonies on conventional culture media, but maintain their patheogenicity, may become latent infection escaping detection to threaten enviroment and human security. With the development of modern molecular biology technique and metagenomics, it provide new research method and opportunity for uncul- tured microorganism in the environment. Recently, with the application of the metagenome technique, ge- netic fingerprinting technical etc, it becomes more and more popular. Simultaneously, along with this state become maturity in the laboratory. It provides a new research route for development and exploitation the uncultured microorganism.

Shan Qi soy has busting bags, bacteria sum overproof, continue acidification and other problems occasionally during the storage. It's probably caused by the Lactobacillus continue growth in the soy. We tried expounding the relationship between growth and producing acid when Lactobacillus growing in the thin fermented material.

Background The fundus autofluorescence (FAF)can reflect the function of retinal pigment epithelium(RPE) cell.As an invasive examination,it has been extensive used in retina disease,but there has not any report in syphilitic posterior uveitis.Objective This study was to characterize and contrast the FAF and fundus fluorescein angiography (FFA),indocyanine green angiography (ICGA) findings in patients with syphilitic posterior uveitis.Methods A retrospective series of cases observational study was designed.The clinical data of 27 eyes from 18 patients with syphilitic posterior uveitis were included in Shanghai First People's Hospital from 2010 May to 2012 October,and all the patients were diagnosed by serologic and ophthalmic tests.The patients were assigned to acute stage group(with the course ＜2 months)and chronic stage group(with the course ≥ 2 months).FFA,ICGA and FAF were performed respectively on all the patients,and the examination results were compared and analyzed.Results In the affected eyes with syphilitic posterior uveitis,the FFA image showed a retinal vasculitis sign and mottle-like fluorescence appearance in posterior pole and equator zone,and some affected eyes exhibited edema of optic disc and macula.Hypoautofluorescence zone was seen in the acute stage group and cystoid macular edema was found in the chronic stage group.ICGA presented with a wider damage of RPE,especially in the later phase of ICGA.A confluent of hyperautofluorescence with hypoautofluorescence in the posterior fundus,punctiform hyperautofluorescence as well as hypoautofluorescence in papillitis and macular edema were found on the FAF image.Conclusions The pathological basis of syphilitic posterior uveitis is retinal vasculitis and papillitis.ICGA indicates the damage of choroid membranes and RPE,and FAF reflects a metabolism disorder of RPE in the acute stage and atrophy and loss of RPE in the chronic stage.FAF is helpful for the diagnosis of syphilitic posterior uveitis as an assistant index.

Effects of different drying methods including sun drying, steamed, boiled, constant temperature drying (at 40, 50, 60 °C) on appearance, hardness, rehydration ratio, dry rate, moisture, total ash, extractive and polysaccharides contents were studied to provide the basis of standard processing method for Tulipa edulis bulbus. The results showed that the treatments of sun drying and 40 °C drying showed higher rehydration ratios, but lower dry rate, higher hardness, worse color, longer time and obvious distortion and shrinkage in comparison with other drying methods. The treatments of 60 °C constant temperature drying resulted in shorter drying time, lower water and higher polysaccharides content. Drying time is shorter and appearance quality is better in the treatment of steaming and boiling compared with other treatments, but the content of extractive and polysaccharides decreased significantly. The treatments of 50 °C constant temperature drying led to similar appearance quality of bulb to commercial bulb, and it resulted in lowest hardness and highest dry rate as well as higher rehydration ratio, extractive and polysaccharides content, moderate moisture and total ash contents among these treatments. Based on the results obtained, 50 °C constant temperature drying is the better way for the processing of T. edulis bulbus.

Objective To investigate the value of MR perfusion imaging in early detection of findings following arterial chemoembolization of hepatocellular carcinoma Methods Twenty eight consecutive patients with pathologically-confirmed HCC were evaluated. All patients underwent MR perfusion imaging at pre-TACE and 3 to 10 days after TACE. The negative enhancement integral (NEI) ,the time to peak(TTP) ,the maximum slope of decrease (MSD) , the signal enhance ratio (SER) were acquired from MRI software FuncTool 2. 5.36a Version. Statistical analysis using SPSS 14, least significant difference test (t test) were utilized. Results The time intensive curve of tumor was observed to descend rapidly to reach the peak at pre-TACE studies, whereas it descended slowly to reach the peak on post TACE studies. The Value of TTP and SER prior to TACE were(51.2 ± 10. 3) s, 60. 6 ± 36. 3 respectively, and post TACE (43.7 ± 12. 0)s, 41.2 ±27. 5 respectively. The values of TTP and SER post TACE were lower than those prior to TACE (P ＜ 0. 05). The value of NEI prior to TACE was 108.7 ± 58.9, and after TACE 149. 6 ±80. 1 and there was statistically significant difference (P ＜0. 05). The Value of MSD post TACE were lower than those prior to TACE, but there was no statistical significance (P ＞ 0. 05). Conclusion PWI is a very sensitive imaging technique that can be used to monitor early dynamic changes of HCC following TACE.
