Objective To investigate the expressions of RUNX3 and CyclinDl in pancreatic carcinoma and their significance. Methods Expressions of RUNX3, CyclinD1 in 47 cases with pancreatic carcinoma, 18 cases with cystadenoma of pancreas and 12 normal pancreas cases were detected by immunohistochemistry, and the relationship between their expressions and clinicopathological parameters was analyzed. Results The positive expression rates of RUNX3 in pancreatic carcinoma, cystadenoma of pancreas, normal pancreas cases were 57.4％ (27/47), 94.4％ (17/18), 100％ (12/12); the positive expression rates of CyclinD1 in pancreatic carcinoma, cystadenoma of pancreas, normal pancreas cases were 72.3％ (34/47), 44.4％(8/18), 8.3％ (1/12). RUNX3 expression was not related to the age and sex, but it was negatively associated with clinical staging, lymph node metastasis, the differentiation degree (P ＜0.05 ). CyclinD1 expression was not related to the age and sex, but it was positively associated with clinical staging, lymph node metastasis, the differentiation degree (P ＜0.05 ). The expression of RUNX3 and CyclinD1 was negatively associated (r = - 0.375, P = 0.009). Conclusions The expression of RUNX3 is decreased in pancreatic carcinoma. The expression of CyclinD1 is increased in pancreatic carcinoma. They may play an important role in the carcinogenesis and progression of pancreatic carcinoma.

Objective To investigate the expression of histone acetylated H3 and H4, methylated H3K4 and H3K9 in diffuse large B-cell lymphoma (DLBCL). Methods The expression of histone acetylated H3 and H4, methylated H3K4 and H3K9 were examined by SP immunohistochemistry technique in lymphoid tissue of 40 cases with DLBCL and 16 cases with proliferative lymphadenitis. Results The expression of histone acetylation of H3 and H4 were lower than that in proliferative lymphadenitis. Histone methylated H3K4 was lower in expression and H3K9 was in higher expression. There was a positive correlative expression between the global histone acetylation of H3 and H4, the global histone acetylation of H3, H4 and histone methylation of H3K4. Conclusion Improper modification of histone acetylations and methylations may play an important role in pathogenesis in DLBCL.

SUMMARY Hemophilia A is aninherited bleeding disorder, lack of coagulation factorⅧ( FⅧ) , and if combined with intracranial malignant tumor, the operation risk is very high. Department of Pediatric Sur-gery in Peking University First Hospital used coagulation factor replacement therapy, succeeded in the operation of 2 cases of intracranial malignant tumor with hemophilia A in children, with no abnormal bleeding events. The establishment of the multi subject cooperation group before operation, good preoper-ative preparation, enough alternative factors, and close postoperative monitoring, are the key to the suc-cessful treatment.

Objective To explore the effect of general intervention in improving the psychological condition of healthy pregnant women. Methods Totally 96 pregnant women who made prenatal visits in our obstetrics and outpatient department were divided into the control and the intervention group stochasti-cally. The intervention group started from first prenatal visit. The general intervention measures included cognitive intervention, the behavioral intervention, family coping intervention and psychological intervention with self-designed relaxation exercises. While conventional prenatal visit, propaganda and nursing were im-plemented to the control group.Self-made general questionnaire and symptom checklist 90 (SCL-90)were used to survey and analyze the results. Results Post-natal depression and anxiety of the control group was obviously higher than that of the prenatal. The Post-natal obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility, terror and bigotry in the intervention group were greatly alleviated. Com-pared with the control group, obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility and terror of the intervention group were significantly different (P<0.05). The depression improved while the difference was not evidently differenL Conclusions Delivery had great influence on the psychological status of women,especially anxiety and depression. General intervention measures like psychological relax-ation exercises can improve the psychological condition of healthy pregnant women obviously,especially de-pression.

Purpose To investigate the corre1ation of the epiderma1 growth factor receptor( EGFR)gene mutation and amp1ification and protein expression with occurrence and deve1opment of non-sma11 ce11 1ung cancer( NSCLC),and to exp1ore the re1ationship be-tween the mutation and amp1ification of EGFR gene and other c1inica1 patho1ogica1 parameters. Methods qRT-PCR,FISH and immu-nohistochemistry were used to detect EGFR gene(exons 18,19,20 and 21)mutation,amp1ification and protein expression in paraf-fin-embedded tissues of NSCLC. Results EGFR gene(exons 18,19,20 and 21)mutation rate was 58. 18%(32/55)in NSCLC with qRT-PCR techno1ogy,in which the occurrence rate of exon 19 de1etions and exon 21 mutation of L858R was 87. 50%(28/32). EGFR gene mutation rate was significant1y different in gender,smoking history and patho1ogica1 type(P<0. 01),but no statistica1 sig-nificance in age,1ymph node metastasis and TNM staging(P>0. 05). EGFR gene amp1ification rate was 23. 64%(13/55)and its protein expression rate was 70. 91%(39/55). Both EGFR gene mutation and amp1ification was c1ose1y corre1ated(P<0. 05),but the two states of EGFR gene and its protein expression had no corre1ation(P>0. 05). Conclusion EGFR gene mutation with high pro-tein expression of NSCLC is common1y found in fema1e,no-smoking and adenocarinoma patients,who are main candidates of a tyrosine kinase inhibitor( TKI)screening. EGFR gene mutation and amp1ification is typica11y corre1ated,but their consequence is unknown, which needs to be further investigated. EGFR gene mutation and amp1ification is not consistent with protein expression,its under1ying machanism is to be determined.
