Journal of Chinese Physician 2001;0(10):-
Objective To elucidate the significance of expressive change in tissues of breast carcinomas.Methods Expression of PTEN protein was detected by immunohistochemistry (SP) in breast carcinomas?atypical intraductal hyperplasia?normal breast tissue. Results The positive rate and expressive intensity of PTEN protein in breast carcinoma were lower and weaker than those in atypical intraductal hyperplasia and normal breast. The intensity of PTEN protein expression was associated with differentiation degree of breast carcinoma, the poorer differentiation of breast carcinoma , the weaker expression of PTEN protein. Comparing with breast carcinoma, the PTEN expression level of atypical intraductal hyperplasia was higher , but It was lower than normal breast tissue. it is helpful for us to assess the carcinogenesis probability of atypical intraductal hyperplasia by detecting the PTEN.

Objective To explore the effect of educational mode on children' s social adaptive capacity (SAC) through investigating its change of children into kindergarten one year later. MethodsFor this study, participants were divided into three groups, namely study group (SG), control group Ⅰ ( CG Ⅰ ) and control group Ⅱ( CG Ⅱ ). ①SG :30 ~ 47-month-old children at their entrance at one kindergarten of Xi' an city were study by the follow-up study method. There were 119 participants in this trial except 22 lost- visitors. The scores of children's SAC were evaluated at their entrance time and one year later respectively, according to the Social Adaptation Scale for Infant-Junior Middle School's Student Revised by Zuo Qi-hua. ②Control group(CG) :The children,whose classes were randomized,of five classes were divided into CG Ⅰ and the other four classes were CG Ⅱ. There were 107children aged at 30 ~ 46 months in CC Ⅰ , 94 children aged at 42 ~ 59 months in CG Ⅱ. The scores of their SAC were also evaluated according to the same scale on September 2006. The cross-section investigation were used to CG Ⅰ and CG Ⅱ. Results① The mean total score of SAC in SG was higher at one year later ( 10. 52 ± 0.77 ) than that at their entrance time( 10.22 ±0.52) (P<0.01) ,and the total score of SAC in SG was lower at their en trance time than that of CG Ⅰ (10.49 ±0.06)(P<0.01 ). ②There was no significant difference in children's SAC between SG at the final stage( 10. 52 ± 0.77 ) and CG Ⅱ(10.40 ± 0.67 ) (t = 1.500, P > 0.05). ③There were no significant difference in children's SAC between boarding care mode( 10.34 ± 0.68 ) and day care one( 10.32 ±0.56) (t = 0.182, P > 0.05 ). ④There were no significant difference in children' s SAC between male ( 10.42 ±0.73) and female( 10.51 ±0.68) in the kindergarten.. ConclusionThe gathered living mode can promote the child SAC development, and the boarding care mode or day care one in one year has no effect on children' s SAC.

Objective To study the diagnosis and treatment of protracted bacterial bronchitis (PBB) in children. Methods Children with PBB conifrmed by bronchoscopy were recruited from May 2013 to April 2015 . The clinical data were retrospectively analyzed. Results All 31 cases include 18 boys and 13 girls were recruited. 28/31 were younger than 6 years old. They all complained of wet cough, some of them were reported with wheeze ( 17/31 ) and with ruttle in the lungs ( 16/31 ). White blood cell were in normal range ( 18/31 ) or slightly elevated ( 13/31 ). The C-reactin protein was in normal range ( 28/31 ). Chest X-ray test of 16 cases were normal. Twenty-four cases taken chest computerized tomograph scan, 5 had a sign of tracheobronchial stenosis. The purulent bronchitis without tracheobronchial stenosis were conifrmed by bronchoscopy. Four cases had tracheomalacia. The medians of proportion of neutrophil were 80% in bronchoalveolar lavage lfuid (BALF). The pathogens were identiifed in BALF in 17 cases, 6 with Streptococcus pneumoniae, 6 with Haemophilus parainfluenzae, 3 with Moraxella catarrhalis, 2 with Staphylococcus aureus and 1 with Haemophilus influenzae. The symptoms were improved in all cases and co-amoxiclav was prescribed to most cases when discharged. The course of antibiotics therapy was 2-4 weeks in 23 cases, and more than 4 weeks in 8 cases. Twenty-three ( 23 ) cases were cured but 8 of them relapsed. Another 8 cases were improved but not completely remitted, 7/8 were cured by further treatment for concomitant diseases such as nasosinusitis and allergic rhinitis. Conclusions Children with PBB are typically younger than six years old, and presented with prolonged wet cough and parent-reported wheeze, normal or with ruttle in the lungs. A conifrmed diagnosis was reached by bronchoscopy. The antibiotics therapy were effective, the course should be more than 2-4 weeks, however, relapse were common. When antibiotics therapy does not lead to complete remission, concomitant diseases should be considered.

Objective: To evaluate the efifcacy and safety on clopidogrel combining proton pump inhibitor (PPI) for treating the patient after percutaneous coronary intervention (PCI) by Meta analysis.
Methods: We searched MEDLINE, EMBASE, Cochrane Library and conference databanks, the retrieval time ended at 2014-03 and 14 references were selected for Meta analysis by RevMan 5.2 software. A total of 52274 patients were enrolled and divided into 2 groups, Control group, the patients received clopidogrel, n=43809 and Combination group, the patients received clopidogrel and PPI n=8465. The efifcacy and safety were compared between 2 groups.
Results: Compared with Control group, the patients in Combination group showed increased all cause death rate (OR=1.20, 95% CI 1.05-1.37), re-myocardial infarction (MI) (OR=1.19, 95% CI 1.07-1.33) and in-steut re-vascularization (OR=1.22, 95% CI 1.08-1.39), all P<0.05; while the MACE (OR=1.29, 95% CI 0.98-1.69), in-stent thrombosis (OR=1.22, 95% CI 0.97-1.54) and gastro- intestinal bleeding (OR=0.95, 95% CI 0.55-1.67) were similar between 2 groups, all P>0.05. Further analysis found that PPI (such as omeprazole and esomeprazole) could compete the CYP2C19 enzyme location of clopidogrel, increase the risk of cardiovascular events and decrease the gastrointestinal protection.
Conclusion: Clopidogrel combining PPI may increase the risk of all cause death, MI, in-stent revascularization and decrease the gastrointestinal protection in patients after PCI, especially for omeprazole and esomeprazole which may compete the CYP2C19 enzyme location of clopidogrel.
