The early diagnosis of cholangiocarcinoma is difficult, and the prognosis is poor. The molecular mechanisms underlying the development, growth and metastatic spread of biliary tract cancers are still unclear. The increase in worldwide incidence and mortality of cholangiocarcinoma justifies the impellent need to clarify the intracellular mechanisms triggering the malignant transformation of the biliary epithelium and growth of biliary malignancies. A more complete characterization of the molecular pathology of bile duct cancers could lead to the identification of valid targets for diagnosis and therapy of these devastating malignancies. This review describes the scientific progress made over the past years with regard to the understanding of the molecular processes of cholangiocarcinogenesis.

Objective To study the sensitivity and specificity of oligoclonal bands (OCBs) and intrathecal IgG synthesis rate (IgG Syn) for diagnosis of multiple sclerosis (MS) and the correlation between qualitative and quantitative indices.Methods Albumin and IgG concentrations in the cerebrospinal fluid (CSF) and serum from 30 patients with MS, 40 with other nervous system inflammatory diseases (NID) and 22 with nervous system noninflammatory diseases (NNID) were determined by rate nephelometry method. OCBs in the CSF were detected using isoelectric focusing combined with silver staining, and IgG Syn was calculated. The sensitivity, specificity and positive result likelihood ratio (PRLR) were analyzed.Results There were no significant difference in the abnormal rate of OCBs and IgG Syn between MS group and NID group. When MS and NID groups were compared with NNID group, the difference was extremely significant (all P

Professor XIA Shouren is a famous acupuncture master in China and has devoted his life to clinical practice, teaching and scientific study of TCM. In his 50 years of medical career, he has studied Chinese and western medicine, innovated ancient masters' experiences, adhered to the theory of "less but highly-effective needling", specified at genjie points and deeply explored the specificity of acupoints. Additionally, the acupuncture stfudy has been firstly conducted in the diagnosis and treatment of trigeminal neuralgia in China and his own unique academic thought has been formed. Professor XIA Shouren makes the contribution to the theory, practice and inheritance of acupuncture and moxibustion.

Objective: To explore the personality traits in the people at high risk for schizophrenia.Methods: 188 individuals at high risk for schizophrenia,and 321 normal controls were assessed by Schizotypal Personality Questionnaire(SPQ).Results: The score of negative schizotypal dimension in SPQ in the individuals at high risk was higher than in the normal controls.Conclusion: The people at high risk for schizophrenia have negative schizotypal personality traits which may represent a genetic endophenotype for schizophrnia.

Since the oral rehydration salts solution(ORS) has been used to treat acute diarrhea of children, there are different kinds of ORS in order to satisfy the need of clinical work. They are the initial WHO-ORS, other substances-supplemented ORS and the reduced osmolarity ORS, each of which has their own efficiency and advantage.

Objective To describe the status and analyze the influencing factors of nurses' compassion fatigue and compassion satisfaction in a certain tertiary hospital,which may provide evidences for the emotional management of nurses by nursing managers.Methods A cross-sectional survey was used in this study and 246 nurses were recruited totally.They investigated about compassion fatigue and compassion satisfaction by questionnaires.Results The average score of nurses' compassion fatigue was (30.76± 5.61)points.The average score of nurses' compassion satisfaction was (25.68±4.12)points.There was a significant difference for nurses' compassion fatigue in various wards,and ICU nurses had the top score.There were no significant differences for nurses' compassion satisfaction.Conclusions The nurses' compassion fatigue and compassion satisfaction in this hospital was relatively moderate.ICU nurses' compassion fatigue score was higher than other wards.Education background,professional title,relationship with colleagues,extra work,support from leaders and family members,wards,education background and relationship with colleagues were the influencing factors of nurses' compassion satisfaction score.

Objective To analyze the relationship between autism children and their familial factors,perinatal period high risk factors,blood lead level.Methods Familial factors,perinatal period high risk factors were investigated by autism risk factors questionnaire on 35 autism children diagnosed by diagnostic and statistical manual of mental disorder(DSM-Ⅳ,4th ed) and 35 age and sex-matched healthy children;blood lead level were detected by graphite furnace atomic absorption spectrometry.Results Maternal drug-taken history in pregnancy,neonatal asphyxia,neonatal jaundice and other factors were significantly related to children autism(Pa
