Pancreatic cancer is one of the most malignant gastrointestinal tumors,characterized by a poor prognosis,absence of specific clinical symptoms and signs,prone to metastases and lack of response to conventional therapy.1 year survival rate of this disease increased to about 20 ％ by gemcitabine,but the morbidity and mortality rates are still higher and higher in the whole worldwide.DNA methylation is one of the mechanisms of epigenetics which is the study of heritable changes in gene expression that are not coded in the DNA sequence itself.It seems that DNA methylation indeed plays an important role in the development and progression of pancreatic cancer.

Newborns,especially premature newborns,because of immature of immune function,have high incidence of sepsis.Today sepsis is still an important cause of neonatal death and poor prognosis.Unfortunately,clinical signs of sepsis are non-specific,so early diagnosis and treatment of the newborn infant with suspected sepsis are essential to prevent severe complications.Blood culture is the gold standard for diagnosis of sepsis,but the positive rote is low.Indicators in diagnosis of sepsis included acute phase reaction proteins,cytokines,cell surface antigen and bacterial DNA testing.This article compares and analyzes the indicators in diagnosis of neonatal sepsis.

The immunohistochemical staining showed the connexin 43 (Cx43) was strongly expressed (average gray value, AGV=230±5), distributed at junction area and intercalated disks of cardiocytes in normal rats,and much less expressed (AGV 193±4) (P<0.01) and distribution-disorganized in STZ-induced diabetic rats. This may be associated with the pathogenesis of diabetic myocardial lesions.

Objective To get the information about the infection condition of blood in voluntary donors in Fuling District from 2001 to 2007, so as to take measures to improve blood quality and ensure blood safety.Methods Serum ALT was detected with Reitman-Frankel assay, and HBsAg, anti-HCV, anti-HIV and anti-TP were detected with ELISA.Results A total of 72 868 serum samples from blood donors were detected, in which 5 512 (7.56%) were positive. The positive rates of HBsAg, anti-HCV, anti-HIV and anti-TP were 3.09%, 0.48%, 0.07% and 1.27% respectively, and the abnormality rate of ALT was 2.73%. There was statistical difference of positive rate among various years (from 2001 to 2007).Conclusion The positive rate of blood in voluntary donors decreases year by year. HBsAg was the highest (1.16%), followed by ALT (2.73%), anti-TP (1.27%), anti-HCV and anti-HIV. It suggests that blood quality monitoring should be strengthed to assure blood safety.

Objective To investigate the histopathologic changes of andometrium and research the cause of abnomal uterine bleeding in permenopausal women.Methods The biopsy sample of andometrium of 870 cases with abnomal uterine bleeding in permenopausal women were restrospectively analyzed.Results The most commonly hostopathologic change in andometrium of abnomal ulterine bleeding in permenopausal women is endometrial hyperplasia(76.67%).The most cases were simple hyperplasia(66.12%).3.0%of cases were endometrial carcinoma,most of them were well-differentiated endometrioid adenocarcinoma(88.46%).The morphological features of the endometrial adenocarcinomas is loss of polarity of the endometrial glands.The tumor cells have large round vesicular nuclei,prominent nucleoli and coarse chromatin.In addition,endometrial stroma was instead of by the fibrous and/or granulation tissue type stroma,usually with inflammatory response.Conclusions Abnormal ulterine bleeding occurred mainly in permenopausal period.Endometrial hyperplasia is the main cause of abnomal ulterine bleeding in permenopausal period.Most endometrial carcinomas in perimenpausal period are well-differentiated endometrioid adenocarcinomas.An important differential diagnosis of the endometrioid carcinoma in a curettage specimen is to differentiate it from atypical endometrial hyperplasia and atypical polypoid adenomyoma.

Objective To explore the influence of psychosocial factors and depression-anxiety on the intellectual impairment in early period of cerebral infarct.Method We compared the correlation of the occurence of intellectual impairment and depression-anxiety,negative life events among 98 cerebral infarct dementia index cases and 80 cerebral infarct without dementia index cases and 87 control subjects.Result Anxiety states have 74.49％ cerebrol infarct dementia index cases,60％ cerebrol infarct without dementia index cases,and 14.94％ control subjects,Depression states have 74.49％ cerebrol infarct dementia index cases,51.25％ cerebrol infarct without dementia index cases,and 20.69％ control subjects,Negative life events have 78.57％ cerebrol infarct dementia index cases,63.75％ cerebrol infarct witout dementia index cases and 13.79％ contrbl subjects.Conclusion The mood and sensibilities problems of depression anxity(especially of anxity) have a neagative status on the intellegence impirment of cerebral infarct.The correlates of post stroke depression-anxity states analysis were paralysis and position of focal lesion.The negative life events influenced the occuring of intelligence imparement post-cerebral infarct without anxity-depression mood and sensibilities problemes.

Objective To explore the influence of behaviour.individuality-personality factors on the intellectual impairment in early period of cerebral infarct.Methods To compare the correlation of the occurence of intellectual impairment and behaviour individuality among 98 cerebral infarct dementia index cases and 80 cerebral infarct without dementia index cases and 87 control subjects.Results A-type behaviour have 63.27％ cerebrol infarct dementia index cases,47.75％ cerebrol infarct without dementia inedx cases,and 35.63％ control subjects.(EPQ)P >60,63.2％ cerebral infarcl domentia index cases,35％ cerebrol infarct without demcntia index cases,and 20.69％ control subjects.(EPO)N>55,42.86％ cerebrol infaret demcntia index cases,38.75％ cerebrol infarct without dementia index cases and 24.14％ control subjects. Conclusion A type behaviour play on important role on intelligence impairment in post cerebral infact.Psychone drviduality and unsteady mood were manly mood feature of cerebral infarct,especially important post cerebral infarct intelligence impairment.

Therapeutic effect of pancreatic cancer depends on early detection and effective treatment.The early diagnosis of pancreatic cancer is so difficult that the discovery of pancreatic cancer is often in mid and late stages,so the treatment of meaning is not so satisfying.In recent years the rapid study of proteomics has brought great hope in the early discovery of pancreatic cancer to make it the post-genome era of functional genomics research in hot areas.Separating and identifying the serum、juice and tissue of patients with pancreatic cancer to find out the different proteins between normal and sick individuals can provide theoretical base and new ideas for the pathogenesis and early diagnosis of pancreatic cancer.

The therapeutic response of anti-vascular endothelial growth factor (VEGF) differs among individuals.According to the changes of central retinal thickness,intraretinal fluid,subretinal fluid,best corrected visual acuity and other morphological or functional manifestations after treatment,the performance of the treated eyes can be classified as optimal response,poor response and non-response.A variety of factors could account for poor or non-response to anti-VEGF,such as genomic polymorphism and specific genomic risk alleles,lesion characteristics,vitreous and macular structural abnormalities,resistance to anti-VEGF drug,and the role of pericytes and others.The common counter measures include increasing the dosage,shortening the injection interval and replacing with another alternative drug,inhibition of pericytes,relieving vitreomacular anatomical abnormalities.It is still worthy of further exploration that how to assess individual reasons for non-response,so that we can give proper treatment to reduce the excessive use of anti-VEGF drugs and improve the clinical management of ocular neovascularization diseases.

Objective To investigate the effect of ectopic pregnancy tubal resection or common disease retention on female reproductive endocrine and menstrual traits.Methods 286 patients with ectopic pregnancy lapa-roscopic operation were selected.According to the different treatment methods,the patients were divided into resection group (n =199),retention group 87 cases,in surgical operation on the third day and the thirtieth day and tested for female reproductive hormone (P,LH,FSH,E2 )and human chorionic gonadotropin (hCG).Results Resection group in the third day after surgery of FSH[(8.5 ±4.9)IU /mL]was significantly higher than that of preserving group[(3.9 ± 0.9)IU /mL],with significant difference (t =5.44,P <0.05),the amounts of LH,E2 ,P and HCG were insignificant (t =0.56,1.24,0.82,all P >0.05).30 days after the surgery,there was no significant difference between the two groups in FSH,LH,E2 ,P and HCG (t =0.92,0.77,1.02,0.65,all P >0.05),but at the age of more than 40 years old and bilateral absence of fallopian tube in patients with,menorrhagia and menstrual cycle change obviously,and female ovarian endocrine function to reduce the clinical symptoms.Conclusion Tube resection has some influence on the ovarian function of tubal ectopic pregnancy,especially older,lack of bilateral fallopian tube.
