Objectives: To study the reliability and sensitivity of serum transferrin receptor(sTfR) and sTfR/SF in assessing iron status,and explore the efficacy for monitoring early iron deficiency. Methods:941 women at reproductive age from Hebei Province and Shunyi county were included in the study. We determined the serum ferritin (SF)、zinc protoporphyrin (ZPP) and hemoglobin (Hb), and divided them into four groups: iron normal, IDS (iron deficiency store),IDE (iron deficiency erythropoiesis),IDA (iron deficiency anemia), according to the current criteria for assessing iron status. We randomly selected 189 aliquotes of serum from four groups to determine their sTfR and calculated the ratio of sTfR/SF, ie, sTfR/LogSF、Log (sTfR/SF). Results: sTfR increased significantly according to ID status of different stages,but sTfR/SF greatly increased in all stages. sTfR correlated with the conventional iron status parameters significantly, and could reflect the different aspects of iron status. The efficacy of Log (sTfR/SF) in identifying iron store deficiency reached 99%,higher than sTfR/LogSF and sTfR. sTfR can effectively identify functional iron deficiency,with the efficacy of 83%. Conclusion: sTfR and sTfR/SF all are promising for assessing iron status and screening iron deficiency in women at reproductive age.

Objective To characterize clinical features and prognosis of pediatric cutaneous mastocytosis. Methods Clinical data on 183 cases of pediatric cutaneous mastocytosis were collected and retrospectively analyzed. Some patients were followed up. Results Of the 183 patients, 136 (74.3%)had urticaria pigmentosa, 43 (23.5%) mastocytoma, 4 (2.2%)diffuse mastocytosis. The first attack of mastocytosis occurred at birth in 21 (48.8%)patients with mastocytoma and 35(25.7%)patients with urticaria pigmentosa, within 6 months after birth in 17(39.5%)patients with mastocytoma and 78(57.3%)patients with urticaria pigmentosa, and within 2 years after birth in 179(97.8%)out of the 183 patients. Of 33 patients with detailed description of symptoms, 10 had concomitant symptoms, which were flushing in 9 patients. Forty-five patients were followed up for 3 - 6 years (average, 4 years). The follow-up showed that skin lesions completely regressed in 1 patient with urticaria pigmentosa at 11 years of age, partially regressed in 18 patients. Lesions regressed completely at 8 years of age in 1 patient with mastocytoma, and subsided within 1 year after skin biopsy in 7 patients. Oral antihistamines could control the symptoms of mastocytosis, such as flushing, whealing and blistering, and oral glucocorticoids could effectively control the recurrence of generalized blisters and bullae in patients with diffuse mastocytosis. Conclusions Urticaria pigmentosa appears to be the most common type of cutaneous mastocytosis in children, followed by mastocytoma. Mastocytoma occurs most frequently at birth, while urticaria pigmentosa within 6 months after birth. Oral antihistamines may control inflammatory mediator-related symptoms. Serious diffuse mastocytosis may be controlled by systemic glucocorticoids.

Objective To investigate the HBV- positive pregnant women about the knowledge of the route of hepatitis B transmission, hepatitis B hazards, health care during pregnancy, announcements of child- care to explore targeted and effective health education model with self- designed question-naires. Methods Nurses in obstetrics department carried out this questionnaire investigation in the outpa-tients of HBV- positive pregnant women, after that the results underwent statistic analysis. Results The overall knowledge of HBV- positive pregnant women in announcements of child- care, health care during pregnancy and hepatitis B hazards was not very well, and the announcements of child- care was the lowest, followed by health care during pregnancy and hepatitis B hazards. The route of hepatitis B transmission was better, but still not satisfactory. The education should highlight these areas. Well- educated women were better than those who lack education. The age between 20 to 30 years old was better. Conclusions The HBV-positive pregnant women is lack of heath knowledge, so we should gave health intervention in a multi- level, multi- stage standardized and a variety of ways.

Objective The study aimed to analyze the clinical features and the causes of hospital death among the 5720 acute myocardial infarction(AMI)patients from Cardiology Center,Beijing Chao-Yang Hospital during the last 8 years. Methods A total of 5720 AMI patients received treatment in the Cardiology Center from January 1st ,2002 to December 31th ,2009 were retrospectively reviewed. All patients were classified according to age into 3 groups of ≤45,46 -75,and ＞ 75 years old. The morbidity,cause of death ,whether they had the PCI therapy,mortality after PCI and the impact of gender on the cause of death were observed respectively. Results The morbidity rate of male was significantly higher than female in all three groups,and the study also found that the morbidity rate of female was significantly higher in the group of ＞ 75 years old,which however was still lower than that of male. The AMI patients were more likely to accept PCI therapy,which could significantly reduce the mortality rate. The top 3 causes of death included acute heart failure(AHF),cardiogenic shock(CGS)and AHF combined with CGS. In addition,AHF caused significantly more death in female and older(＞ 75 years old)patients. Conclusions The morbidity rate of AMI patients in Beijing Chao-Yang Hospital increased year by year. And PCI therapy could reduce the mortality rate of all groups. Revascularization treatment seems to be feasible and safe for the patients older than 75 years old.

Objective To explore the efficacy of low tidal volume ventilation strategy in children with acute hypoxia respiratory failure (AHRF).Methods A total of 79 hospitalized children with AHRF from Aug 2006 to Jul 2011 in PICU of Kunming Children's Hospital were enrolled in this study.The observation group in-cluded 55 children who received low tidal volume ventilation strategy (6-8 ml /kg),while the other 24 children (control group)were given traditional mechanical ventilation (10-12 ml /kg).Oxygenation situations such as PaO2 ,PaCO2 ,PaO2 /FiO2 ,oxygen index and blood gas pH value,organ function,mechanical ventilation complica-tions,hospitalization days and expenses in PICU and the mortality were observed.Results (1)PaO2 ,PaO2 /FiO2 and oxygen index in the observation group were better than those in control group after 24 h mechanical ventilation [(68.51 ±7.53)mmHg(1 mmHg =0.133 kPa)vs.(61.64 ±9.28)mmHg,(162.9 ±21.84)mmHg vs.(152.1 ± 19.03)mmHg,and 18.85 ±4.1 vs.26.53 ±5.2,respectively],and there were significant differences between two groups (P ﹤0.05);and there were also significant differences between two groups in the results after 48 h and 72 h mechanical ventilation.(2)The PaCO2 was (47.48 ±10.52)mmHg after 24 h in observation group,while the PaCO2 in control group was (30.17 ±6.59)mmHg,and it suggested excessive ventilation.(3)Mechanical venti-lation time (7.6 ±3.1)d and hospitalization days (12.8 ±3.6)d were shorter in observation group(P ﹤0.01). Barotrauma (7.3%)and mortality (20.0%)in observation group was significantly lower than those in control group (29.2%,41.6%;P ﹤0.01).The number of damaged organs in observation group was lower than that in control group (P ﹤0.05).Conclusion Low tidal volume ventilation with appropriate positive end expiratory pressure could improve oxygenation,prevent alveolar collapse,reduce complications and mortality for children with AHRF,it should be applied for the treatment of children with AHRF.

Objective To observe the security and efficacy of sevoflurane inhalation in combination with remifentanil controlled hypotension in patients undergoing functional endoscopic sinus surgery.Methods Forty pa tients undergoing elective functional endoscopic sinus surgery were randomly divided into propofol group (group P)and sevoflurane group(group S).In group P,patients received remifentanil 0.2μg · kg-1 · min-1 and propofol 4 ～6mg · kg-1 · min-1 intravenously,those in group S received remifentanil 0.2pg · kg-1 · min-1 and continuous inhalation of sevoflurane 2 ～ 3％,the end-tidal concentration was 1.1 ～ 1.7MAC.MAP was retained at 65 ～ 75 mmHg in the two groups.MAP and HR were recorded before controlled hypotension (T1),5min after controlled hypotension (T2),30min after controlled hypotension(T3),the termination of surgery(T4) and 5min after the termination of surgery(T5).Record the patient opening eyes time,wake extubation time,duration of surgery,blood loss.Also observed with or without respiratory depression,drowsiness,restlessness,nausea,vomiting and other adverse reactions.The same surgery fell surgical field quality rating according to Fromme operative field score table.Results Compared with T1,MAP(F =73.68) and HR(F =24.60) decreased significantly(P ＜ 0.05) at the other time points.There was no statistically significant difference in MAP(t =0.90) and HR(t =1.00) at the same time points between the two groups (P ＞ 0.05).Extubation time (t =0.44),duration of operation (t =1.23),operative field score (t =0:43) and blood loss (t =0.58) has no significant differences (P ＞ 0.05).Conclusion Inhalation hypotension by sevoflurane is feasible and safe in the functional endoscopic sinus surgery.It shows good quality of surgical field and less adverse reactions.

To investigate the advantage of using the medical sodium hyaluronate gel undergo goniosynechialysis, and to compare the difference of the viscoelastic agent and perfusion fluid by clinical control study.
●METHODS:Totally 103 cases (103 eyes) patients who had angle- closure glaucoma (ACG) with cataract all in Beijing Tongren Hospital affiliated to Capital Medical University, from September 2012 to February 2013. All the patients had primary glaucoma or recurrence ACG with cataract. Their intraocular pressure (lOP) could be controlled in normal value using one or two anti -glaucoma medications. We divided all the patients into two groups by chance. Experimental group had 53 cases (50 eyes), and control group had 50 cases (53 eyes). Two groups all had been performed phacoemulsification combined with goniosynechialysis by the same experiential operator. But experimental group did goniosynechialysis using the medical sodium hyaluronate gel, control group did goniosynechialysis using perfusion fluid. We observed the change of lOP, central anterior chamber depth and anterior chamber structure of two groups in postoperative 1mo.
●RESULTS: SPSS19. 0 statistics software was utilized to analyze the data, This study selected one- side test α =0. 05, adopted paired t - test or two- sample t - test. We obtained that experimental group lOP decreased 12. 42 ± 0. 04mmHg, anterior chamber depth increased 1. 276 ± 0. 201mm; that control group lOP decreased 6. 56 ± 0. 08mmHg, anterior chamber depth increased 0. 852 ± 0. 132mm. And experimental group anterior chamber angle opened more widely than the other group, the comparison had statistical significance (P<0. 05).
●CONCLUSlON: ln phacoemulsification combine with goniosynechialysis,use medical sodium hyaluronate gel do goniosynechialysis can more effectively decrease lOP. This because the medical sodium hyaluronate gel has high glutinousness, it can separate angle of anterior chamber and controlling lOP effectively.

Objective To understand the job burnout status of bank staff and analyse the relationship between job burnout and self-efficacy,job satisfaction.Methods The job burnout,self-efficacy and job satisfaction of 8 942 bank staff was surveyed by Maslach burnout inventory-general survey(MBI-GS),general self-efficacy scale (GSES) and job satisfaction scale (JSS) respectively.Results A total of 8 942 questionnaires were issued and 7 486 valid questionnaires were returned.The score of self-efficacy in male was significantly higher than that in the female(P ＜0.05).There was no significant difference in job satisfaction score between male and female(P ＞ 0.05).The score of emotional exhaustion (EE) in female was significantly higher than that in male,while the score of reduced personal accomplishment(RPA) was significantly lower than that in male (P ＜ 0.05);there was no significant difference in depersonalization (DP) score between male and female (P ＞ 0.05).The EE,DP and PAL scores of bank staff with post-graduate education were significantly lower than those with high school/secondary school and junior college/undergraduate (P ＜ 0.05);the DP and PAL scores of bank staff with junior college/undergraduate were significantly lower than those with high school/secondary school(P ＜ 0.05);there was no significant difference in EE score of bank staff between junior college/undergraduate and high school/secondary school(P ＞ 0.05).The EE score of age ＞ 50 years old bank staff was significantly lower than that of age ＜ 30 years old,30-40 years old and 41-50 years old (P ＜0.05);there was no significant difference in EE score among age ＜30 years old,30-40 years old and 41-50 years old bank staff (P ＞ 0.05).The DP score of 41-50 years old bank staff was significantly higher than that of age ＜ 30 years old (P ＜0.05);there was no significant difference in DP score among age ＜30 years old,30-40 years old and 41-50 years old bank staff (P ＞ 0.05).There was no significant difference in PAL score among all age groups (P ＞ 0.05).The three dimensions of job burnout had significant negative correlation with self-efficacy and job satisfaction (P ＜ 0.05).Conclusion Bank staff have a certain degree of job burnout.Age,sex,and education level maybe the influence factors of job burnout.Improvement of self-efficacy and job satisfaction may help to reduce the job burnout.
