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

The interaction betweenYan-Hu-Ning (YHN) and bovine serum albumin (BSA) was investigated in order to provide further theoretical evidences on action mechanism study between YHN and proteins within the organism. Under optimal conditions, the interaction between YHN and BSA was studied by fluorescence quenching, ultraviolet absorption spectrometry and synchronous fluorescence spectroscopy. At the temperature of 283.15 K, 298.15 K and 313.15 K, quenching constant (KSV) and speed constant (Kq) were calculated by S-V curves. Static quenching constant (KLB) was obtained by L-B double reciprocal equation. Double logarithmic equation was used to calculate the binding constants (Kb) and the number of binding site (n). Thermodynamic equation was used to obtainΔH,ΔS,ΔG. Hill’s coefficients (nH) was obtained by Hill equation. The results showed that at three different temperatures, along with the increasing of YHN concentration, the fluorescence intensity of BSA decreased regularly. The value of KSV, Kq, KLB, Kb, n and nH decreased with the increasing of temperature;ΔG < 0,ΔH < 0,ΔS < 0; n was approximately equal to 1; nH > 1. It was concluded that YHN-BSA complex quenched the intrinsic fluorescence of BSA. The mechanism of fluorescence quenching was static quenching. The main binding forces were deduced as hydrogen bonds and Van der Waals forces from calculated values of thermodynamic parameters. YHN and BSA can form a binding site, which indicated certain binding interaction between YHN and BSA. YHN can be stored and transported by protein within the body. Free energy was produced to transformΔG into negative value. It showed that the process of binding between YHN and BSA was spontaneous. The nH was more than 1. It indicated that YHN had positive cooperative effect. The primary binding site was located at subdomainⅡA. The synchronous fluorescence spectra showed certain influence on the conformation of BSA by YHN. It led to the weakening of polarity within BSA and the binding site to be closer to the tyrosine.

To investigate different effects of fiscal health expenditure, household spending on health and social health expenditure on narrowing the gap between urban and rural health resource allocation. Methods: With the relevant data of China’ s medical and health through 1985-2011 years, taking methodology of the state space model to estimate the varying-time elasticity of different types of expenditures on urban and rural health resource allocation gap. Results: For narrowing the gap, household health expenditure played the leading role, fiscal health expenditure played smaller role and the social health expenditure played the supplementary role; the elastic of different health expenditure proportion was fluctuated before 2002, which became stable after 2002; it is easy to improve the “hard conditions” rather than the “soft conditions” . Conclusion: To accelerate the process of urban and rural medical security system integration, it is inevitable to establish an efficient configuration mechanism for urban and rural health expense, balanced develop urban and rural medical insurance system and scientifically guide social health investment.

Objective To investigate the clinical effects of Huayutongmai decoction in treating patients with carotid atherosclerotic plaques .Methods Prospectively analyzed 102 cases with carotid atherosclerotic plaques were divided into the control group and observation group according to random number table method ,51 cases were in each group.The patients in the control group were given the Simvastatin Tablet only ,and the patients in the observation group were given the treatment of Huayutongmai decoction .The CAD,IMT,volume of plaque,PI and lipid levels were detected.The clinical efficacy and adverse reaction were observed after treatment of three months .Results After treatment of three months,the CAD,IMT,volume of plaque,PI(t=0.97,1.83,0.65,1.43) and levels of lipid(TG, TC,HDL-C,LDL-C and AI,t=1.86,1.88,1.42,1.85,1.14) of the observation group were better than those of the control group,but with no significant(all P>0.05).Conclusion Huayutongmai decoction in treating patients with carotid atherosclerotic plaques has better clinical efficacy ,can improve lipid metabolism ,eliminate and stabilize CAS to some extent ,which is worthy of clinical application .

Objective Apaf-1 is a key factor involved in activating the Caspase system in apoptosis. The aim of this study was to evaluate the significance of Apaf-1 on the apoptosis process induced by chemotherapeutic agent. Methods We established Apaf-1 hyper- and hypo- expression system by transferred sense and anti-sense Apaf-1 cDNA into cultured AGS cell line. And meanwhile human cyt-c, Apaf-1, caspase-3, bax, and bcl-2 gene expressions were measured by RT-PCR method. Results Cyt-c, caspase-3, and bax gene expressions increased significantly after sense Apaf-1 transfection. On the contrary, anti-sense Apaf-1 transfer has minus effects on cyt-c, caspase-3, and bax gene expressions. No significant changes have been found on bcl-2 gene expression after transfection process.Conclusions Cyt-c pathway may play an important role in the apoptosis induced by chemotherapeutic drugs. The early expression of cyt-c and Apaf-1 may be the key procedure of cyt-c release from mitochondria and of caspases activation.
