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 explore the efficacy of flupenthixol melitracen in the treatment of functional dyspepsia (FD) and its effects on receptivity expansion and visceral sensitivity.Methods A randomized,controlled,multi-centre study was carried out.The FD patients with depression were divided into anti-depression group and control group.The patients of both groups received omeprazole and mosapride treatment for eight weeks.The patients of anti-depression group added flupenthixol melitracen and psychotherapy.Before the treatment,by the end of the second,fourth,sixth and eighth week of the treatment,the scores of upper gastrointestinal symptoms and adverse effects of the patients of the two groups were recorded,the psychological status was evaluated by Hamilton depression scale and the gastric receptivity expansion and visceral sensitivity were assessed by water loading test (WLT).The data were analyzed by t test and chi-square test.Results Among two hundred and fifty enrolled FD patients with depression,245 patients (129 in anti-depression group,116 in control group) were enrolled in intention-to treat analysis.Before the treatment and by the end of the eighth week of the treatment,the scores of upper gastrointestinal symptoms of anti depression group were 12.23±4.45 and 2.31±2.13 (t=22.837,P=0.008),the control group were 12.29± 4.62 and 8.58±3.76 (t=6.708,P=0.184).By the end of the eighth week of treatment,the difference between the two groups was statistically significant (t =16.261,P＜0.05).By the end of the fourth and eighth week of treatment,the total effective rates of the improvement of upper gastrointestinal symptoms of anti-depression group were 76.0％ (98/129) and 83.7％ (108/129),control group were 14.7 ％ (17/116) and 25.9 ％ (30/116),the differences between the two groups were statistically significant (x2 =92.191 and 83.117,both P＜0.05).By the end of the eighth week of treatment,the total effective rate of the improvement of depression of anti depression group was 71.3％ (92/129),which was higher than that of control group (23.3％,27/116),the difference between two groups was statistically significant (x2 54.434,P＜0.01).Before the treatment,the maximum WLT volume of anti depression group was (850±130) mL,by the end of the eighth week of treatment was (1400±210) mL (t=25.292,P＜0.01).Before the treatment and by the end of the eighth week of treatment,the maximum WLT volumes of control group were (800± 120) mL and (960±140) mL (t=9.345,P＜0.01).All the adverse effects of anti depression therapy were mild.Conclusion The treatment of flupenthixol melitracen can improve the efficacy in patients with FD,relieve the depression status,improve gastric receptivity expansion and visceral sensitivity with a good safety and tolerability.

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.

Objective To realize the clinical and epidemiological characteristics of measles,and explore effective measures to control measles epidemic.Methods Clinical data of 554 hospitalized measles children between January 2009 and December 2013 were analyzed retrospectively.Results All children had fever,cough,and skin rash,507 (91.52% )had typical clinical manifestations of measles,47(8.48% )had mild manifestations;the major population were children aged≤6 months(n= 176,31.77% )and 7-8 months (n= 346,62.45% );132 (23.83% )children had contact history of confirmed measles,19(3.43% )measles children’s mothers also developed measles (all were cases of 2013),227 (40.97% )children had history of repeated infusion or hospitalization in large medical institutes dur-ing the measles incubation period (all were cases of 2013,there were measles children who had infusion or hospitali-zation in the same hospital during the same period). The peak incidence of measles usually occurs in January-May. Conclusion Intensive immunization of measles for young women of reproductive age and vaccination with“pre-mea-sles vaccine”for early infancy,and strengthening the medical management of fever outpatients are important meas-ures to prevent measles epidemic.

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.
