Hyperthyroidism with periodic paralysis is common in clinic,the curative effect of peroral drugs on it is not satisfactory. In order to evaluate the treatment of 131 I for periodic paralysis in patients with hyperthyroidism, fouty two patients with hyperthyroidism complicated with periodic paralysis were put on p.o. 5.0 9.0 mCi 131 I Na treatment and the remission rate of periodic paralysis was observed.The total effective rate was over 95%. It can be concluded that 131 I could be used as a routine therapy for periodic paralysis in most patients with hyperthyroidism for its safety and efficiency.

Objective To study the relationship between voice acoustic analysis(VAA) and voice handicap index (VHI) in patients with vocal cord polyps,and to investigate the characteristic of the VHI.Methods 35 subjects with normal voice and 35 patients with vocal cord polyps underwent VHI,were tested by VAA.Results The parameters such as APQ、jitter、shimmer、NHR in patients with vocal cord polys were much higher than those in the normal voice group.The average score of VHI was 43.32?4.66,while the average score of the normal voice group was 12.51?1.88.There was no correlation between VHI and VAA.Conclusion Since there is no correlation between VHI and VAA in patients with vocal cord polys.One can not speculate the VHI score by the voice acoustic analysis.

Effective treatments of acute ischemic stroke include the specialist wards (stroke units) with multidisciplinary treatment team receiving treatment and intravenous thrombolytic therapy.However,only a few patients can receive these treatments.Telestroke can improve the thrombolytic rate of acute ischemic stroke on site in hospitals for lacking of specialists and enable stroke care maintained at a high level in rural areas.This article reviews telestroke in the treatment of acute ischemic stroke and the roles of nurses in telestroke.

Objective: To establish an HPLC method to detect the limit of 5-hydroxymethylfurfural in Yueju Baohe pills.
Methods: A Zafex Acutfex PW-C₁₈ column（4.6 mm×250 mm, 5 μm） was adopted with mobile phase consisted of acetonitrile-0.1% formic acid aqueous solution（2:98）at the flow rate of 1.0 mL·min^-1. The column temperature was 40 ℃ and the detective wavelength was set at 284 nm.
Results: The linear range of 5-hydroxymethylfurfural was 0.491 9-122.98 μg·mL^-1 (r=1.000). The average recovery(n=6) was 97.99% with RSD 0.61%. All of the RSDs for precision,repeatability and stability met the methodological requirements. According to the proposed limit, 17 of the 65 batches of samples did not meet the requirements, and the failure rate was 26.15%.
Conclusion: The established method is suitable for the limit test of 5-hydroxymethylfurfural in Yueju Baohe pills.There was a significant difference in the content of 65 batches of samples. It is necessary to investigate the limit of 5-hydroxymethylfurfural in Yueju Baohe pills.

OBJECTIVE: To observe the effects of different concentrations of arsenic trioxide (As(2)O(3)) on apoptosis and proliferation of human lung cancer cell line A549 in vitro under hypoxia and normoxia. METHODS: A549 cells were treated with 0, 1, 2, 4 micromol/L As2O3 for 12, 24 and 48 h under hypoxia (5% O(2)) and normoxia (21% O(2)). The proliferative inhibition rate of A549 cells was measured with methyl thiazolyl tetrazolium assay, and the apoptotic rate of A549 cells was detected by Annexin V/propidium iodide (PI) double staining. RESULTS: Under normoxia and hypoxia, 1, 2, 4 micromol/L As(2)O(3) could significantly inhibit the proliferation of A549 cells and induce the apoptosis of A549 cells. The results depended on the drug concentration and action time. And the hypoxia couldn't influence the effects of As(2)O(3). CONCLUSION: As(2)O(3) can inhibit the proliferation and induce the apoptosis of A549 cells under hypoxia and normoxia.

Objective To investigate the prevalence and the transmission of oqxAB gene in clinical strains of Escherichia coli and Klebsiella pneumoniae .Methods Nonduplicate clinical isolates of E.coli (n=72)and K .pneumoniae (n=49)were col-lected.The oqxAB gene was amplified by PCR.The product was sequenced.Plasmid conjugation experiments were done in oqxAB-positive E.coli and K.pneumoniae strains to detemine whether oqxAB gene is located in plasmid.The MICs and mu-tant prevention concentrations (MPCs)for ciprofloxacin were determined in transconjugants with oqxAB gene by agar dilution method.Results The oqxA,oqxB and oqxAB were identified in 15,4,and 7 of the 72 strains of Escherichia coli and 4,1,and 34 of the 49 strains of K.pneumoniae,respectively.The oqxAB gene was positive in 2 (2/16)ciprofloxacin sensitive and 5 (5/56)ciprofloxacin resistant E.coli strains,in 8 (8/14)ciprofloxacin sensitive and 26 (26/35)ciprofloxacin resistant K. pneumoniae strains,respectively.The E.coli and K.pneumoniae strains with or without oqxAB did not show different sus-ceptibility to ciprofloxacin.The oqxA and oqxB sequences from E.coli and K.pneumoniae showed 99% similarity to the se-quences of GeneBank accession number AB601773.1 and accession number FJ975561.1,respectively.The oqxAB gene was successfully transferred in 4 of the 5 oqxAB-positive E.coli strains.The MIC of ciprofloxacin was 0.25-0.5 mg/L against the transconjugants,31-62 times higher than the MICs for the recipient strains.The MPC of ciprofloxacin was 8-16 mg/L against the transconjugants,32 times higher than that for recipient strain J53.The oqxAB gene were not transferred in K. pneumoniae. When the MIC of ciprofloxacin was ≤0.062 5 mg/L,the MPC of ciprofloxacin was 0.25-0.5 mg/L for K.pneumoniae strains with or without oqxAB.When MIC was 0.25-0.5 mg/L,the MPC of ciprofloxacin was 2-16 mg/L for K .pneumoniae strains with or without oqxAB .Conclusions oqxAB gene is present in E .coli and K .pneumoni-ae .The oqxAB gene spreads through plasmid in E .coli.The nonsiginificant difference of oqxAB prevalence between ciproflox-acin sensitive and ciprofloxacin resistant strains indicates that oqxAB gene may mediate low level resistance to ciprofloxacin in E.coli.The E.coli transconjugants of oqxAB gene can produce high level resistance under the selection pressure of ciproflox-acin.The high level resistance in K .pneumoniae under selection pressure of ciprofloxacin is not associated with oqxAB gene, but related to the ciprofloxacin MIC against these strains.

Objective To explore the expression and clinical significance of EphA2 and E-eadherin in colorectal carcinoma.Methods The expression of EphA2 and E-eadherin in 67 cases of eoloreetal carcinoma and 28 cases of normal large intestine tissues were determined by immunohistochemieal method(S-P method),and their relationship to elinicopathological characteristics were analyzed.Results The positive expression of EphA2 and negative expression of E-cadherin in colorectul carcinoma tissues were significantly higher than those in normal intestine tissues(P<0.01).F111e positive expression of EphA2 and negative expression of E-eadherin were positively correlated with tumor histological grade,invasive depth and lymph node metastasis(P<0.01 orP<0.05),but not correlated with tumor～ross type(P> O.05).The expression of EphA2 was negatively related with E-cadherin.Conclusions The abnormal expression of EphA2 and E-cadherin may be together involved in the development and progression of eolorectal carcinoma,It may be a good marker for monitoring the malignant degree and the prognosis of colorectal carcinoma by combining E-eadherin and EphA2.

Objective To prepare the HPV genotyping control materials. Methods Three hundred cervical smears with different HPV genotypes were collected and detected by surface plasmon resonance and sequencing. The primers for specific genotype were designed according to GenBank. The recombinant plasmid was constructed through PCR amplification, ligation and transformation. Thirty recombinant plasmids were identified through PCR amplification, sequencing, and the sequences were compared using BLAST. Results The collected HPV infectious samples contained 30 different genotypes including HPV 6,16,18 and so on.The fragment sequences of PCR amplification were concordant with the designed. The fragment sizes of the other types ranged from 1 500 to 2 000 bp except HPV CP8304. And the 30 recombinant plasmids identified by PCR were concordant with the target. The identity of BLAST was 99%. In the fragment of 1500 bp in length, 11 bases were inconsistent with the reference sequence. Conclusions Genotyping control materials were developed successfully. The human papillomavirns genotyping control materials covered all the most common types and included 14 types with high-risk, 3 types with medium-risk and 13 types with low-risk.
