Objective To explore the risk factors for in stent stenosis (ISR) in coronary artery disease in elderly patients undergoing postoperative percutaneous coronary intervention (PCI).Methods We chose 418 cases undergoing PCI in our hospital.There were 263 males and 156 females,aged from 60 to 79 years,average (71.3--8.9)years in this study.Under the same conditions of treatment strategies,we collected all possible risk factors for ISR in patients undergoing postoperative PCI,and statistics were analyzed.Results All patients were rechecked at 1 year after PCI.104 cases (24.9％) occurred ISR,and 314 cases (75.1％) were diagnosed without ISR.Multiple logistic analysis showed that,and sex had little effect on ISR incidence (P＞0.05).Body mass index(OR=9.54,95％CI:6.542～32.154,P=0.002),smoking history(OR=26.01,95％CI:5.532～122.238,P=0.000),hypertension(OR=15.72,95％CI:3.240～76.026,P=0.001),diabetes mellitus(OR=11.98,95％CI2.667～53.835,P=0.001),history of high cholesterol(OR=8.98,8,95％CI2.164～37.283,P=0.003),exercise time (OR 5.63,8,95 ％ CI2.004 ～ 25.385,P=0.013)had positive correlations with ISR incidence.Conclusions Effective control of risk factors including smoking,hypertension,diabetes,high cholesterol,proper exercise,and weight control can help prevent the development of ISR in elderly patients with postoperative PCI.

Objective To discuss the relationship between C-reactive protein and prognosis of acute coronary syndrome. Methods C-reactive protein of 60 acute coronary syndrome patients was evaluated. The individuals were divided into two groups:One group with higher CRP level and another group with normal CRP level. The following-up duration was 6 months. After correct therapy, the morbidity of re-angina, arrhythmia, heart failure, re-infarction and cardiac death was compared. Results The morbidity of re-angina, arrhythmia, heart failure, re-infarction, cardiac death was 46.3%(19/41), 43.9%(18/41),9.76%(4/41),22.0%(9/41),7.32%(3/41)respectively in higher CRP level group; The morbidity of re-angina, arrhythmia, heart failure, re-infarction was 15.8%(3/19),10.5%(2/19), 5.3%(1/19),5.3%(1/19)respectively in normal CRP group and there was no cardiac death accident. There was significant different between the two groups. Conclusions CRP plays an important role in the onset of acute coronary syndrome, and its level is related with the higher morbidity of re-angina, arrhythmia, heart failure, re-infarction and cardiac death.

According to the 'hygiene hypothesis', the intestinal microbes would not only regulate local immune status, but also affect systematic immune homeostasis, which may play an important role in the pathogenesis of allergic diseases. This review will mainly focus on investigating the intricate relationships among intestinal microbes, immune system and allergic diseases. Multiple factors affecting gut microorganisms may influence the immune homeostasis directly and later become risk factors of allergic diseases. This point of view may pave the way for the design of new interventions to the diseases.

Liaoning, the populous province, has too many management staff in training residents, so it is very necessary to explore the information-based method for the training management. This platform has realized the whole-course network management of resi-dent training, and many common functions such as the application of training base , on-line registra-tion, on-line real-time monitoring of trainees' daily training state, on-line graduation exam arrangement, and inquiry of statistical information of trainees in the province . It saves human and management costs , improves management efficiency , and orderly pushes forward the standardized of residents training.

3) in control group (χ2=5.42,P=0.02).Conclusions Gemcitabine chemotherapy combined with HIFU treatment was more effective for pancreatic tumor growth control and pain relief without more adverse events,which was effective and safe.

Objective:To study the preparation technique and quality standard for new Shengfa pills. Methods: The best water extraction process of the medicinal herbs was optimized by orthogonal test using stilbene glucoside content and dry extract percent as the indices. The content of stilbene glucoside was determined by HPLC, and Hyssop and Chinese angelica in the preparation were identified by TLC. Results:The optimized preparation conditions were as follows:12-fold water was used in the 3-time extraction with 1 h for each time. The spots in TLC were clear without interference from the negative control. Conclusion:The preparation process is reasona-ble and feasible in techniques with controllable quality.

Objective To compare treatments of intra-articular calcaneal fractures with and without bone graft in foot and ankle surgery.Methods A comprehensive search was conducted on line for all English research articles published from January 1990 through December 2010 dealing with open reduction and internal fixation with and without bone graft for intra-articular calcaneal fractures.Two reviewers evaluated each study to determine whether it was eligible for inclusion and collected the data of interest.Meta-analytic pooling of group results across studies was performed for the 2 treatments.Results The systematic review identified 32 qualified primary studies with 1281 fractures.No significant differences were found in postoperative infection, osteoarthritis or subtalar fusion between the 2 treatments ( P ＞ 0.05) .The average full weight-bearing time in bone graft treatment was significantly lower (5.4 weeks) than in non-graft treatment (10.5 weeks) .The mean B(o)hler angle was significantly larger and long-term loss of collapse significantly lower in bone graft treatment than in non-graft treatment.The bone graft treatment had a lower American Orthopaedic Foot and Ankle Society (AOFAS) score (71.4 points vs.80.5 points) but a higher Creighton score (89.9 points vs.81.0 points) compared with non-graft treatment.Pooled mean results showed no significant differences in the weighted excellent-to-good rate between the 2 treatments (excellent 35%, good 40%, fair 21% and poor 4% for the bone graft treatment versus excellent 34%, good 42%, fair 14%, and poor 10% for the non-graft treatment).Conclusions Open reduction and internal fixation with bone graft for intra-articular calcaneal fractures may lead to better reduction of B(o)hler angle and early return to full weight-bearing without increased risk of postoperative infection.However, since more cases of joint depression and comminuted fracture have been included in the bone graft group in the present study, a prospective controlled comparative study with a large scale of samples is still needed.

Objective To learn the relationship between working pressure and mental health for nurse of transfusion room in pediatric department.Methods 120 nurses of transfusion room whose working years above half a year were investigated by questionnaire from January 2010 to December 2011.Results The maximal score of working pressure was working environment and resource (3.27±0.47),while the minimum was interpersonal relationship (1.80±0.68).The score of SCL-90 of the research group was higher than domestic model.More working pressures of transfusion room in pediatric department were positive correlated with SCL-90.Conclnsions In order to keep nurse sound in body and mind,the working pressure should be desolved in many ways.

The neutron activation analysis of a stable isotope (58Fe)was used successfully in the study of iron absorption from different diets in children suffering from iron deficient anemia. The method was correct and convenient, and uninjured to human body. The principle, procedure and the control of errors were also discussed. The iron absorbability of the balance diet,soy protein diet and soy protein diet plus vitamin-C were (group average?SD) 12.0? 3.6%, 10.7?4.7%, and 18,1?3.6% respectively. According to the results and the animal experiments which were reported in another paper, we agreed that soy protein unfavor or reduce the bioavailability of iron from diet, which was made by International Nutritional Anemia Consultative Group (INACG) and others, but it is still a disputing question. The data of iron absorbability from diets in children suffering from iron deficient anemia and the method of neutron activation analysis of a stable isotope (58Fe) have not be seen up to now in China. This paper will be valuable for studing, preventing and treating iron deficient anemia in our country.

In order to clarify the disputing view-points in some publications, that the soy products are whether unfavourable or not to the bioavailability of diet iron, we estimated the relative bioavailability of the iron from soy flour by hemoglobin regeneration method in rats suffered from iron deficiency anemia. In this experiment the ferrous sulfate was used as a standard, wheat flour as a vehicle, and the pig blood powder as a reference substance. The iron content in the regeneration diet fed to rats of each group was 32 ppm in total, and among it 24ppm was originated from (1) soy flour, (2) soy flour plus wheat flour (half and half), (3) pig blood powder, (4) pig blood powder plus wheat flour (half and half), and (5) ferrous sulfate respectively.The experimental results showed that during the 5-week regeneration period the regenerated hemoglobin level of the rats of corresponding groups were (1) 6.6?1.6→9.4?1.7, (2) 7.0?0.9→10.4 ?1.5, (3) 6.4?1.6→ 11.4?1.4, (4) 6.1?0.6-11.1?1.9, and (5) 5.3?1.2-12.8 1.0, thereby the percentage of iron relative bioavailability of five groups were (1)45.4, (2)65.0, (3)74.0, (4)72.0, (5)100.0 respectively. The iron from soy flour showed a lowest bioavailability aalong the different diet sources in our exper-iment, and therefore the iron from soy products was unfavourable to prevent and treat the iron deficiency anemia. We also made some discussions and suggestions in this paper.
