Cervical cancer is one of the most common and deadliest cancers in females worldwide. Despite the treatment methods of surgery, radiotherapy and chemotherapy are maturing, the prognosis of patients with recurrent, advanced or metastatic cervical cancer remains poor. Molecular targeted therapy provides new hope for these patients. This review focuses on the advances in agents targeting vascular endothelial growth factor pathway, epidermal growth factor receptor, mammalian target of rapamycin, histone deacetylases and cyclooxygenase-2 in cervical cancer.

Objective To induce experimental autoimmune myasthenia gravis (EAMG) rabbits by using T?125～147 Methods Peptides T?125～147 were synthesized referring to the residue sequence of acetylcholine receptor of Torpedo California and the rabbits were inoculated with the peptides Clinical manifestation was graded in 4 levels Electrophysiological function was assessed by repetitive nerve stimulation (RNS) and single fibre electromyography (SFEMG) tests Anti peptides antibodies were evaluated by enzyme linked immunosorbent assay (ELISA) Student t test was used to analyze the difference between the EAMG and healthy rabbits Results Following the second inoculation,the rabbits appeared weakness Clinical symptoms were improved by neostigmine At 3,5 and 10 Hz,the decrement of compound muscle action potential (CMAP) and the mean jitter (MCD) of the immunized rabbits were higher than in the healthy ones The percentage of decrement of CMAP in order of the control group and the T?125～147 group were:3 Hz: 1 625?1 317,25 375?7 945; 5 Hz: 2 000?1 732,25 625?9 102; 10 Hz: 1 750?1 392,28 875?8 709.Following the above sequence,the MCD were:3 Hz: (9 875?1 126) ?s,(25 875?7 945) ?s; 5 Hz: (11 375?0 916) ?s,(27 500?3 381) ?s; 10 Hz: (12 375?1 061) ?s,(31 000?4 811) ?s Anti peptide antibodies in immunized groups were significantly higher than those in the control group Conclusion T?125～147 might be served as the immunogenic to induce EAMG in rabbits,accompanied by elevation of anti peptide antibodies and the blockage of neuromuscular transmission

Objective To study the chemical constituents in the roots of Hemerocallis fulva. MethodsCompounds were isolated from the CHCl3and n-butanol fraction of the EtOH extract by repeated column chromatography and their structures were identified by spectral analysis and physicochemical properties. Results From the CHCl3 and n-butanol fraction of the EtOH extract in the roots of H. fulva,ten compounds were isolated and identified as terresoxazine (Ⅰ),11-keto-?-boswellic acid (Ⅱ),hopane-6?,22-diol (Ⅲ),hecogenin (Ⅳ),stigmast-4-en-3?-ol (Ⅴ),stigmast-4-en-3-one (Ⅵ),?-feruloyloxy acid (Ⅶ),(E)-3,4-dihydroxyl cinnamic acid (Ⅷ),(E)-p-methyl cinnamic acid (Ⅸ),and vanillic acid (Ⅹ). Conclusion Compounds Ⅰ-Ⅳ,and Ⅶ are isolated and identified from the plants of Hemerocallis L. for the first time.

The abnormal expression of MUC15, a novel cell membrane-associated mucin, has been reported to predict poor survival in several cancers. The aim of the present study was to examine the expression of MUC15 in glioma and its correlation with clinicopathological features, including the survival of patients with glioma. The mRNA expression level of MUC15 was determined by RT-PCR, quantitative RT-PCR (RT-qPCR) and Western blotting in seven normal brain tissues and seven glioma tissues, respectively. The protein expression level of MUC15 was immunohistochemically detected in paraffin-embedded samples of 317 glioma tissues and 115 noncancerous brain tissues. The association of MUC15 expression levels with the clinicopathologic features and the prognosis was analyzed. The results showed that both mRNA and protein levels of MUC15 were significantly increased in glioma as compared with those in noncancerous brain tissue. Moreover, MUC15 overexpression was positively correlated with the advanced clinical stages of glioam patients (P<0.01). Furthermore, MUC15 expression levels were significantly correlated with the progression of glioma (P<0.001). Survival analysis indicated that glioma patients with higher MUC15 expression had a significantly shorter overall and 5-year survival time than those with low MUC15 expression. Multivariate analysis suggested that MUC15 overexpression was an independent factor for prognosis (hazard risk: 3.216; P=0.009). It was concluded that MUC15 is overexpressed in glioma tissues. Its overexpression correlates with tumor progression and it is a potentially unfavorable prognostic factor for patients with glioma.

Objective To explore the clinical characteristics and diagnosis of mycoplasma pneumoniae(MP) pneumonia showing lobar pneumonia.Methods Patients from Jan.2004 to Dec.2005 were selected as researching case,which had samptoms and signs of respiratory in clinic,the chest Xray shown lobar pneumonia,the MP of down respiratory′s secretion detected by polymerase chain reaction(PCR) and MP-IgM of serum detected by indirect hemagglutination were positive.The clinical data of them were reviewed.Results MP pneumonia showing lobar pneumonia was same to streptococcus pneumoniae pneumonia in clinic,but it had some characters:1.majority of the lobar MP pneumonia were children being student;2.the process was long,the samptoms of respiratory was tipical,the continuous fever was few,and the infectious samptoms was not obvious as streptococcus pneumoniae pneumonia;3.the injury to lung was more and tipical;4.the increase of white blood cell,neutrocyte and C-reactive protein were not clearly as to streptococcus pneumoniae pneumonia,but the absorbing of lung′s focal was relatively fast;5.the ?-lactams antibiotic was not effective,but macrolides was effective.Conclusions Clinical characters of MP pneumonia are needed to master,the variety of chest X-ray changes and differentiate from other pneumonia infected by other are needed to notice.

Objective To explore the relationship between the incisure changes in the intracranial vertebral artery (VA) segments on transcranial Doppler (TCD) and their diseased regions. Methods Incisure changes in VA intraeranial segments on TCD in 24 cases were found. Digital subtract angiography (DSA), computed tomography angiography (CTA)or coler Doppler flow imaging (CDFI)of carotid arteries were performed to confirm their diseased regions. Results (1)The group with end-systolic and pre-diatolic wide incisures was found in 9 cases: DSA or CTA showed 5 cases with severe stenosis, 2 cases with occlusion and 2 cases with congenital tenuity of the affected vertebral artery proximal part(VA-Pr). Within the above 8 cases, ipsilateral subclavian artery (SubA) was normal, 1 case was complicated with moderate stenosis of ipsilateral SubA,and 1 case was complicated with occlusion of contralateral SubA. Haemodynamics test showed (1)negative; (2)The group with systolic incisures was in 12 cases, and 12 patients were divided into two groups based on the haemodynamics test : ① positive group was in 6 cases. DSA showed that VA-Pr was normal but SubA had impaired with different degrees; ② negative group was in 6 cases. DSA showed VA-Pr was with occlusion in 4 cases and 2 cases was with congenital tenuity; The above 2 cases were complicated with stenosis of ipsilateral SubA and in 4 cases ipsilateral SubA were normal; (3) The group with small vibrated sharp waves on Doppler was in 3 cases, and DSA showed VA-Pr occlusion in 3 cases. In the 3 cases,one case was complicated with occlusion of ipsilateral SubA. Blood stealing was present in cervical muscular branches but not present between vertebral arteries . Ipsilateral SubA were normal in 2 cases. Haemodynamic tests showed negative. Conclusions VA incisures were not only present in the early subclavian steal syndrome (SSS) but also were found in the patients with impaired SubA . However, blood steal pathway is imperfect, and would be found in affected VA-Pr or congenital tenuity. Haemodynamic tests can help identify the above situation. The TCD screening method can be used in the routine diagnosis for SubA and VA from proximal to intracranial segments involvement, but there are limitations to some extent. It needs to combine with DSA and CDFI for diagnosis.
