Objective: To investigate the expression of EMS1 in laryngeal carcinoma and its clinical signifi-cance. Method:The expression of EMS1 protein was measured in 40 samples of, 40 samples of para carcinoma tis-sues (which were near to cutting margin of laryngeal carcinoma tissuse over 0. 5 cm) ,and 20 samples of normal la-ryngeal mucosa as controls by Flow Cytometere( Epics-XL Ⅱ ). Results:The quantity and percentage of EMS1 pro-tein expression in laryngeal carcinoma tissues was significantly higher than those in para carcinoma and in normal laryngeal mucosa tissues respectively(P<0. 05). There was no significant expression difference between the para carcinoma tissues and normal laryngeal mucosa tissues. There were positive correlation between the expressions of EMS1 protein and metastasis, pathological grade and clinical stage in laryngeal carcinoma. But there were not rela-tionship with patients' clinical classification, tumor size, smoking history, age and sex. Conclusion: The high ex-pression of EMS1 may contribute to the carcinogenesis and development of laryngeal carcinoma. The expression of EMS1 protein is an important index of judging differentiation, infiltration, metastasis and staging of laryngeal car-cinoma.

Infectious disease hospitals are obliged to cope with public health emergencies such as outbreak of infectious diseases.Such hospitals are required to make early detection,early containment,proper management,reasonable preplans,timely training,targeted drills,reasonable deployment of hospital resources,appropriate protection for hospital staff.General hospitals should also cope with prevention and control of infectious diseases to some extent,and work with infectious disease hospitals hand in hand to better cope with such outbreaks.

Objective To obtain the antigen and antibody of JC virus(JCV)VP2.Methods The JCV VP2 gene were amplified from a cerebrospinal fluid sample by polymerase chain reaction (PCR)and confirmed by sequencing.Then,the gene was cloned into plasmid pET32a(+)to construct recombinant prokaryotic expression vector pET-32a(+)-VP2.The recombinant plasmid was transformed into the competent E.coli BL21.Induced with isopropyl-β-D-1-1 thiogalactopyranoside (IPTG),E.coli BL21 were subsequently crushed by ultrasound.The gene expression in the supernatant was analyzed by Western blot.Thereafter,the expressed protein was purified by isoeleetric point method.The polyclonal antibody against JCV VP2 protein was obtained from the BALB/c mouse immunized with the purified protein.Results The VP2 fusion protein was expressed in the E.coli BL21.The recombinant fusion protein was expressed by IPTG induetion with relative molecular mass of 58.5×10~3.Sodium dodecyl sulphate-polyacrylamide gel electrophoresis(SDSPAGE)analysis showed that the expression level was highter after 6-10 h of IPTG induction.The recombinant protein had good antigenicity which was confirmed by BALB/c mice immunized with the protein.Conclusions The successful expression and purification of VP2 fusion protein and the antibody will be valuable for the study on the biological function of VP2 and JCV epidemiologieal investigation.

OBJECTIVE: To summarize the clinical effect of TPF regimen in the treatment of hypopharyngeal carcinoma and explore various clinical factors affecting treatment efficacy. METHOD: The clinical data of 20 cases with hypopharyngeal carcinoma, who received TPF treatment, were analyzed retrospectively. After two courses of chemotherapy, based on radiographic outcomes, next treatment plan was developed. To sum up the clinical information, including the clinical type, patterns of tumor growth, pathologic type, tumor stage, lymph node metastasis, age and so on. To analyze possible influencing factors affecting curative effect. RESULT: (1) After 20 cases with hypopharyngeal carcinoma received two courses of TPF treatment, the effect was evaluated. Objective response rate was 65%. (2) In patients with hypopharyngeal carcinoma, the efficacy of TPF therapy was significantly related to the clinical type, patterns of tumor growth and pathologic type; there was no statistical significance in tumor stage, lymph node metastasis and age. CONCLUSION According to the clinical type, patterns of tumor growth and pathologic type of hypopharyngeal carcinoma, resistance to chemotherapy in hypopharyngeal carcinoma can be assessed, which provides important basis for designing individualized treatment plan.

Objective To discuss the clinical characteristics and prognosis of 15 children with hand foot and mouth disease (HFMD) and acute flaccid paralysis (AFP) who were admitted to Beijing Ditan Hospital during the outbreak of HFMD in 2008. Method The epidemiology, clinical manifestations, cerebrospinal fluid (CSF),magnetic resonance imaging and prognosis of 15 children with HFMD and AFP were retrospectively reviewed. The recovery of the patients' affected extremities were monitored for 4 weeks. Results The mean age of these patients was (22.47 ± 20.68) months (range: 5～72 months). Acute paralysis developed (3.47 ± 1.68) days after the onset of fever and progressed to maximum severity within (1～2) days. Poliomyelitis-like syndrome was observed in all cases. Of the 15 cases, 10 had monoplegia of lower limbs, two had paraplegia, one had monoplegia of upper limbs and two had quadriplegia. In these cases, the muscle power varied from level 0 to level 4, and six even showed no muscle power in their affected extremities. Thirteen cases developed neurologic complications (encephalitis, meningitis or ataxia) and three had transient urinary retention. Cerebrospinal MRI examination in eight cases showed hyperintense lesions on T2-weighted images, predominantly in the impaired anterior horn regions of the spinal cord (C2～C7 for cases with upper extremity impairments and T12～L1 for cases with lower extremity impairments), and displayed long T1 signals and long T2 signals. In addition, the midbrain, brain-stem or medulla was also involved in four cases who also contracted encephalitis or meningitis. The muscle strength in 11 patients with single lower extremity impairment showed improvements in the distal limb muscles within 4～8 days, and the other cases showed recovery 2～3 weeks later. Conclusions HFMD in combination with AFP most commonly occurs in children aged less than 2 years old. Acute paralysis develops during the early stage of infection and progresses to a maximum severity within 2 days. In most cases described here, paralysis occurred in a single lower extremity and recovered more rapidly than those with all four limbs affected or with single upper extremity impairment . MRI examination is particularly valuable for the diagnosis and prognosis of AFP because of its high sensitivity and accuracy.

OBJECTIVE: To investigate the expression of DcR3 in laryngeal carcinoma and analyze the relation between DcR3 and clinical factors. METHOD: The expression of DcR3 protein in 41 laryngeal carcinoma tissues and 41 para-carcinoma tissues (to cutting margin > 0.5 cm) were measured by Flow Cytometer(Epics-XL II), 15 normal laryngeal mucosa tissues were served as controls. RESULT: (1) The quantitative and qualitative expression of DcR3 protein in laryngeal carcinoma tissues was obviously higher than those in para-carcinoma and normal laryngeal mucosa tissues, respectively (P < 0.05). There was no significant difference for the DcR3 protein expression between para-carcinoma and normal laryngeal mucosa tissues. (2) In laryngeal carcinoma, the expression of DcR3 protein was not significantly related to clinical classification, tumor size, smoking history, patients' age and sex but related to metastasis, pathological grade and clinical stage. CONCLUSION The high level of DcR3 expression may contribute to the carcinogenesis and development of laryngeal carcinoma. So it can be an important index for judging the differentiation, infiltration, metastasis and staging of laryngeal carcinoma.

OBJECTIVE: To investigate the expression of EMS1 and DcR3 in laryngeal carcinoma and analyze the relation of EMS1 and DcR3. METHOD: The expression of EMS1 and DcR3 protein in 41 laryngeal carcinoma fresh samples and 41 para-carcinoma tissues (to cutting margin > 0.5 cm) were measured by flow cytometry, and 15 normal laryngeal mucosa samples were also studied as controls. RESULT: (1) The quantitative and qualitative expression of EMS1 and DcR3 protein in laryngeal carcinoma tissues was obviously higher than those in para-carcinoma and in normal laryngeal mucosa tissues respectively (P < 0.05). There was no significant difference between the expression of para-carcinoma and normal laryngeal mucosa tissues. (2) In laryngeal carcinoma, the expression of EMS1 and DcR3 protein was independent of patients' clinical classification, tumor size, smoking history, patients' age and sex but associated with tumor metastasis, pathological grade and clinical stage. (3) In laryngeal carcinoma, the expression of EMS1 was positively correlated with that of DcR3. CONCLUSION EMS1 was positively related to DcR3, which might play an important role in the carcinogenesis and development of laryngeal carcinoma by synergic effect.
