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 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.

There has been a series of teaching innovation carried out to improve the clinical teaching of seven-year program students in the department of gynecology and obstetirics of Xinqiao hospital.By using case as a guide and problem as foundation,with multimedia and other advanced teaching plan,we paid more attention to the Chinese-English teaching to improve mixed diathesis of these medical students and find out a better teaching model.

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 investigate the clinical features and management strategies of re-pregnant women with chronic hepatitis B virus infection after implementation of two-child policy.Methods A total of 173 women with chronic hepatitis B virus infection in a subsequent pregnancy were enrolled from Hangzhou Xixi Hospital, among whom 91 cases were before implementation of the policy (from January to August 2015, control group), and 82 cases were after policy implementation (from March to December 2016, study group).The clinical data including basic information, pregnancy complications, postpartum complications, delivery mode and perinatal complications were retrospectively analyzed,t test or χ2 test was used for comparison between the two groups.Results There were significant differences in proportion of age>35 years (31.71% vs.16.48%,χ2=5.528), frequency of abortion(3.2±0.3 vs.1.3±0.4,t=5.723), fertility interval with first pregancy[(57.8±21.4)months vs.(40.4±16.6)months,t=6.691],rate of assisted reproduction(14.63% vs.5.49%,χ2=4.066),proportion of abnormal liver function(13.41% vs.4.40%,χ2=4.618),antiviral treatment during pregnancy (34.14% vs.19.78%,χ2=4.561) and proportion of HBV DNA loads >105IU/mL(35.36% vs.20.88%,χ2=4.515)between study group and control group (all P<0.05).The incidences of gestational hypertension(12.20% vs.3.30%), gestational diabetes mellitus(14.63% vs.5.49%),placenta previa(9.76% vs.2.20%),placental implantation(3.66% vs.0), hydramnio (12.20% vs.3.30%), fetal distress (14.63% vs.5.49%) and preterm birth(14.63% vs.5.49%)were also statistically significant between two groups (χ2=4.914, 4.066, 4.524, 3.838, 4.914, 4.066 and 4.066,all P<0.05).The incidence of cesarean section again(50.00%), postpartum hemorrhage(14.63%)and postpartum anemia(19.51%) were significantly higher in the study group than that in the control group(35.16%,4.40% and 8.79%,χ2=3.892, 5.387 and 4.149,all P<0.05).Compared with the control group, the incidence of low birth weight(14.63% vs.5.49%), neonatal asphyxia(19.51% vs.6.59%)and neonatal HBV infection rate(15.85% vs.6.59%)were higher in the study group (χ2=4.066, 6.486 and 3.883,all P<0.05).Conclusions The clinical characteristics of re-pregnant women with chronic hepatitis B virus infection are more complex and suffer greater risk of pregnancy, so antenatal care should be further reinforced after the comprehensive implementation of two-child policy.
