Objectives:To study the expression of PTEN in endometrial carcinoma under different pathological factors and to discuss its relationshipwith the occurrence of endometrial carcinoma and the clinical significance.Methods:The expressions of PTEN in 40 cases of endometrial carcinoma,10 cases of atypical hyperplasia and 10 cases of normal endometria were examined by immunohistochemical method.Result:The positive staining rate of PTEN in endometrial carcinoma was 55.00%,and that in normal endometria was 100.00%.There was no obvious correlation between the expression of PTEN in endometrial carcinoma and different pathological factors such as clinical staging,depth of myometrial invasion and lymph node metastasis.Conclusion:The expression lack of PTEN exists in endometrial carcinoma,and PTEN has an important role in the occurrence of endometrial carcinoma.

The bilingual teaching is a new mode to enhance the synthetic ability of the medical students' foreign languages.The article proposes several manners of guarantying the teaching effect such as strengthening the teacher's quality,applying multimedia to teaching,using unified teaching material and increasing students' interest in learning.

Objective To explore the relationship between mindfulness and rumination of nursing students in clinical practice. Methods Three hundred and sixty two nursing students participated in the survey using Chinese version of mindfulness scale and rumination scale.Results The scores on mindfulness and rumination among the 362 nursing students were 3?18 ± 0?37 and 1?62 ± 0?19,respectively.The mindfulness among them was negatively correlated with their rumination and so it were with the three dimension of mindfulness:awareness in action,non-reactiveness of inner experience and non-judgment on inner experience with the 3 dimensions of rumination(P<0?01 or P<0?05).The 3 dimensions of mindfulness predicted the variance of rumination by 31?1%.Conclusions The mindfulness of nursing students is at moderate level,and their rumination at low level.Therefore,the nursing administrations or educators should further cultivate mindfulness of nursing students to reduce the extent of rumination?

This paper summarized the nursing care of 6 patients with severe aplastic anemia complicated with DIC. The risk of sepsis and severe pneumonia can be reduced through actively nursing and preventing of oral,res-piratory,skin and perianal infections. The chances of bleeding from the skin,nose,and mouth can be reduced by less skin puncture,local medication,cold compresses and compression. Also by monitoring the coagulation indexes, estimating the phase of DIC and observing the bleeding manifestations. Through controlling heparin dripping rate, monitoring coagulation index,reporting to doctors at any time and knowing how to deal with heparin overdose,can increase the safety of heparin administration and improve the clinical application rate of early DIC heparin therapy. Psychological guidance can reduce the risk of cerebral hemorrhage caused by excessive exertion and accidental fall. After treatment and careful nursing,6 patients improved,5 cases were discharged,and 1 case died.

Resveratrolisonekindofpolyphenoliccompoundswidelyexistingingrapesandother plants.Recent studies have documented that resveratrol may play anti-tumor role by mechanisms of anti-oxi-dant,cyclooxygenase inhibition,anti-proliferation,differentiation and apoptosis in gynecological tumors,such as cervical cancer,ovarian cancer and endometrial carcinoma.

133 teeth in 34 children aged 4 to 8 year-old were recruited for the treatment of bilateral maxillary primary canines or primary molars with deep caries,chronic pulpitis or chronic periapical periodontitis under local anesthesia.Buccal infiltration(BI)with conventional syringe(CS)was used for one quadrant,anterior middle superior alveolar anesthesia(AMSA)with computer-controlled local anesthesia de-livery system(C-CLADS)on the contralateral side.The injection duration(s)of CS and C-CLADS was 63.6 ±22.6 and 136.6 ±12.4 re-spectively(P =0.000).The pain perception of C-CLADS injection was significantly lower than that of CS(P <0.05),that during operation was not statistically different(P >0.05).55.9% children preferred C-CLADS anesthesia.

This paper presents a new design method and basic principle for the data acquisition system of the biochemical analyzer. The hardware, software configuration and principle of A/D converter module are also introduced. Field experiment shows that the system is effective and can satisfy related accuracy specification.

In order to improve the performance of the photorefraction device,shorten the detection time and improve the accuracy of measuring,the theory of a new kind of double-cranny eccentric photorefraction device is described.Some features and key point of technology are emphatically pointed out.A method is put forward to determine the ocular diopter by image processing.

Objective To investigate the effect of seasonal variation of blood pressure (BP) on the incidence of cardiovascular and cerebrovascular events in the elderly aged 80 years and over.Methods The 67 patients (aged 80-86 years) with essential hypertension were enrolled, the BP were measured at home, in consulting room, and by 24-h ambulatory BP monitor in every season for 2 years. The incidences of cardiovascular and cerebrovascular events were recorded in the meantime.Results Both systolic BP (SBP) and diastolic BP (DBP) were lower in summer than in any other season (P＜0. 01 ). SBP was higher in winter than in any other season. (P＜0.01), DBP was higher in winter than in summer(P＜0. 01). There were no significant differences in SBP and DBP between spring and autumn. The incidence of cardiovascular and cerebrovascular events were higher in winter and summer than in spring and autumn (P＜0.05). The season (OR= 1. 525, P=0. 001), BMI (OR =1.145, P=0.018) and heart function (OR= 2. 037, P=0.01) were related to the incidence of cardiovascular events. And the season (OR = 1. 604, P= 0. 001 ), history of cerebrovascular disease (OR= 1. 598, P=0. 034), office-measured SBP (OR=0.960, P=0.013) and ambulatory DBP (OR =0. 936, P = 0. 008) were related to the incidence of cerebrovascular events.Conclusions The blood pressure measured by three methods in the elderly aged 80 and over shows that both SBP and DBP are at the lowest in summer; SBP is at the highest in winter, DBP is higher in winter than in summer. There are no significant differences in BP between spring and autumn. The incidences of cardiovascular and cerebrovascular events are significantly higher in winter and summer than in spring and autumn.
