Hepatocellular carcinoma (HCC)is a disease with high incidence and mortality and has become a serious threat to human health. So far,none of the available markers can be used alone for early diagnosis of HCC.Recently identified serum markers with potential clinical value for early diagnosis of HCC are summarized,and their diagnostic sensitivity and specificity,as well as their applications in assessment of progression of the disease,are reviewed.It is suggested that alpha -fetoprotein should be used in combination with other serum markers to achieve accurate diagnosis of HCC at early stages.

Objective To evaluate the symptom improvement of anxiolytics and antidepressant to hemifacial spasm(HFS)patients with anxiety and depression. Methods A total of 60 HFS patients with anxiety and depression were enrolled for the study and divided into experimental group and control group. Experimental group were treated with escitalopram and BTX-A ,and control group only received BTX-A. SAS and SDS were used to test all the patients before and after treatment. Results Both experimental group and control group were significantly improved after BTX-A therapy. There was no different between two groups at 1 week and 1 month,respectively. At 2 weeks and 3 months,more obvious improvement was seen in experimental group. The SAS and the SDS standard average scores of experimental group were significantly decreased compared with the control group. There was statistical significance in control group after 1 month and 3 months treatment(P<0.05),and in experimental group,the differences appeared after 2-week treatment(P<0.05). Additionally,after 1 month treatment,there were statistical differences between the two groups(P<0.05),and experimental group shown a longer effective period compared with control group. Conclusion Anxiety and depression state serves as a complication of HFS ,which is positively correlated with HFS. HFS patients with anxiety and depression benefit better from escital-opram and BTX-A combination therapy than BTX-A alone.

Objective:
To compare the effectiveness of less invasive surfactant administration (LISA) and intubate surfactant extubation (INSURE) on respiratory distress syndrome (RDS) among premature infant, so as to provide insights into improving treatment effects and reducing complications of RDS among premature infants.
Methods:
A total of 71 premature infants with RDS in Anhui Provincial Maternity and Child Health Hospital were randomly assigned into the LISA and INSURE group, and pulmonary surfactant (PS) administration was carried out by LISA and INSURE with basic support therapy and respiratory support therapy. The general information, arterial blood gas analysis before and after treatment, respiratory support time and incidence of complications were collected and compared between the two groups.
Results:
There were 31 cases in the LISA group, with a gestational age of (29.81±0.99) weeks and 22 male cases, and 40 cases in the INSURE group, with a gestational age of (30.02±1.13) weeks and 26 male cases. There were no significant differences in basic characteristics (including gestational age, birth weight, gender, etc.) between the two groups (all P>0.05). After administration, the level of PaO2 was lower in the LISA group than in the INSURE group [(78.35±6.55) mmHg vs. (87.68±8.21) mmHg, P<0.05], the level of PaCO2 was higher in the LISA group than in the INSURE group [(43.03±6.34) mmHg vs. (38.68±9.69) mmHg, P<0.05], and the incidence of bronchopulmonary dysplasia was lower in the LISA group than in the INSURE group (48.39% vs. 72.50%, P<0.05). Linear regression analysis showed that with the duration of LISA administration increase (2-7 min), the minimum heart rate of premature infants increased linearly (β=13, P<0.05).
Conclusions
Compared with INSURE, LISA administration could slowly improve ventilation oxygenation, reduce hyperventilation and incidence of bronchopulmonary dysplasia among premature infants with RDS. The incidence of slow heart rate may be reduced by appropriately prolonging the administration duration.

Objective To study the clinical application of the ITS and β-tubulin gene regions in identification of Aspergillus spp. Methods One hundred and twenty-four Aspergillus strains that isolated from fungal rhino-sinusitis specimens were collected in Beijing Tongren Hospital, Capital Medical University from July 2007 to January 2010. They were identified by morphological and molecular methods. The first one included traditional culture, slide culture, and microscopic examination after lactophenol cotton blue stain and KOH digestion. The second one was amplifying and sequencing the part of ITS and β-tubulin gene and aligned all the sequences in the GenBank, European Molecular Biology Laboratory nucleotide sequence database, and DNA Data Bank of Japan. Results Of the 56 Aspergillus flavus identified by morphological features, fifty-five isolates were identified as Aspergillus flavus and 1 isolates was Aspergillus parasiticus by the ITS and β-tubulin gene region sequence analysis. In the 37 Aspergillus fumigatus identified by morphological method, and all the 37 isolates were identified as species complex of Aspergillus fumigatus by the ITS region sequence analysis, but through the sequence analysis of β-tubulin gene region, thirty-five isolates were identified as Aspergillus. fumigatus and 2 were Aspergillus lentulus. Twenty-one isolates were identified as Aspergillus versicolor by morphological method, but 16 of them were identified as Aspergillus. versicolor and 5 can not be identified to species level by the ITS region sequence. And by comparative-sequence analysis of β-tubulin gene region, the 5 isolates were identified as Aspergillus sydowii,the other 16 isolates were Aspergillus. versilcolor. Ten isolates were identified as Aspergillus nidulans by morphological features, the ITS and β-tubulin gene region sequence analysis. Conclusions β-tubulin gene sequencing is more suitable for identifying Aspergillus, and could identify Aspergillus spp. to species level Sequences of ITS region could only identify Aspergillus spp. to species complex.
