In infants with severe bronchopulmonary dysplasia(sBPD),severe pulmonary lobar emphysema may occur as a complication,contributing to significant impairment in ventilation.Clinical management of these infants is extremely challenging and some may require lobectomy to improve ventilation.However,prior to the lobectomy,it is very difficult to assess whether the remaining lung parenchyma would be able to sustain adequate ventilation postoperatively.In addition,preoperative planning and perioperative management are also quite challenging in these patients.This paper reports the utility of selective bronchial occlusion in assessing the safety and efficacy of lobectomy in a case of sBPD complicated by severe right upper lobar emphysema.Since infants with sBPD already have poor lung development and significant lung injury,lobectomy should be viewed as a non-traditional therapy and be carried out with extreme caution.Selective bronchial occlusion test can be an effective tool in assessing the risks and benefits of lobectomy in cases with sBPD and lobar emphysema.However,given the technical difficulty,successful application of this technique requires close collaboration of an experienced interdisciplinary team.

OBJECTIVE: The aim of this study was to analyze the mediating effect of body dissatisfaction in correlation between obesity and dietary behavior changes for weight loss (DBCWL). METHODS: A total of 680 primary and middle school students were included in this study. Their body height, weight, and waistline were effectively measured, and they were also evaluated to assess their body dissatisfaction, perception of dietary behaviors, and DBCWL. The correlation among these factors was analyzed using mediating effect models. RESULTS: The prevalence of overweight/obesity and abdominal obesity was significantly higher in males than in females (P < 0.05). Overweight/obesity, abdominal obesity, and body dissatisfaction significantly increased the risk for DBCWL (OR = 2.57, 2.77, and 1.95, respectively). Overweight/obesity and abdominal obesity significantly increased the risk for body dissatisfaction (OR = 6.00 and 4.70, respectively). Significant mediating effects of body dissatisfaction were observed in correlation between overweight/obesity and DBCWL and between abdominal obesity and DBCWL (OR = 2.20 and 1.92, respectively; P < 0.05), and the proportions of mediating effects among the total effects were 48.89% and 46.60%, respectively. CONCLUSION Body dissatisfaction might play an important mediating effect in association between DBCWL and obesity, which indicates that guiding children to correctly recognize their body might be more conducive than promoting obese children toward weight loss through dietary behavior changes.

Objective: To study application effect of cardiac remote real-time monitoring system in pre-hospital rescue. Methods: A total of 400 patients with coronary heart disease complicated arrhythmia treated in our hospital were selected. They were chronologically and equally divided into routine monitoring group (received routine bedside 12-lead ECG examination and ECG results were checked regularly by physicians and nurses during bedtime) and remote monitoring group (wore cardiac remote monitoring alert reporter, results were recorded by multi-channel simultaneously and auto-delivery mode was activated). Abnormal results recorded by real-time monitoring and time to identify patient's abnormal condition were compared between two groups, and application effect was evaluated. Results: There were no significant difference in percentages of ventricular tachycardia, supraventricular tachycardia, paroxysmal atrial fibrillation, atrioventricular block, bundle branch block, premature ventricular contraction Lown grade I～II and≥grade III between two groups, P＞0. 05 all. Compared with routine monitoring group, there was significant rise in percentage of patient's abnormal condition identified within 10min (38％ vs. 52％), and significant reductions in percentages of patient's abnormal condition identified within 10～30min (44％ vs. 28％) in remote monitoring group, P＜0. 05 all. Conclusion: Cardiac remote real-time monitoring system possesses the advantages of rapid diagnosis, long transmission distance and simple operation, etc., which is worth extending.

OBJECTIVETo study the effect of polydatin on the expression level of miR-214 and liver function in atherosclerotic mice.

METHODSForty male ApoE(-/-) mice were randomly allocated into 4 groups (n=10), namely the model group, low- and high-dose polydatin groups, and simvastin group, with 10 male C57BL/6J mice serving as the normal control group. Mouse models of atherosclerosis were established by feeding the ApoE(-/-) mice with a high-fat diet. After 12 weeks of treatment, blood levels of glucose, lipids, AST, and ALT and the contents of T-SOD and MDA in the liver tissue were detected. The pathologies of the liver were examined with HE staining, and miR-214 expression in the liver was detected using quantitative real-time PCR.

RESULTSCompared with the normal control mice, the mice in the model group showed significantly increased blood glucose, serum TC, TG, LDL-C, ALT, and AST levels, and MDA contents in the liver (P<0.01), with significantly decreased serum HDL-C level and SOD and miR-214 levels in liver (P<0.01). Polydatin treatment significantly ameliorated such changes in blood glucose, serum ALT, AST, TC, TG, LDL-C, and HDL-C levels, and MDA, SOD, and miR-214 contents in liver tissue (P<0.05).

CONCLUSIONs Polydatin can reduce blood glucose and lipid levels and protect the liver function in atherosclerotic mice possibly by up-regulating the expression of miR-214 and T-SOD and down-regulating MDA in the liver.

It is of vital significance to conduct active post-marketing surveillance of Chinese medicine, as an active response to laws, rules and guidelines issued by the China food and drug administration. The standards for technological specifications based on expert consensus have been drafted. These will provide technological support in evaluating adverse drug reactions (ADRs) or adverse drug events (ADEs). The technological specifications for post-marketing surveillance focus on two surveillance designs; one is a large sample registry study to explore general population ADR/ADE characteristics, the other is a nested case-control study to explore the characteristic and mechanisms of ADRs.

OBJECTIVETo evaluate the effect of bronchoalveolar lavage (BAL) through bronchoscopy in diagnosis and treatment of accidental inhalation of liquid and powdery foreign bodies in children.

METHODTwenty-one cases of accidental inhalation were classified into the following 4 groups according to the materials inhaled: 3 cases inhaled the lipidic material; 2 cases inhaled chemical material; 15 cases inhaled hydrosoluble materials; 1 case inhaled powdery material. Eighteen cases were hospitalized within 3 days after the accidents, which included 16 cases treated within 1 day in hospital. And 3 cases were hospitalized 3 days after the accident. After hospitalization, all patients were immediately treated with direct aspiration and lavage clearance method through bronchoscopy. The inhaled foreign materials were cleared as soon as possible, which reduced the absorption, stimulation and infection of respiratory mucosa. The therapeutic effect was evaluated by endoscopic findings, clinical manifestation, laboratory examination and chest imaging. At the same time, decision was made on the second BAL and the prognosis was estimated.

RESULTTwenty-one cases had dyspnea of certain degree. The bronchial mucous membrane of all the 21 cases showed hyperemia, edema and exudate attached. Lavage fluid looked like broth and contained much of the inhaled material. After two to five times treatment, 18 cases were cured (86%), but 3 cases died (14%). One of these 3 cases fell into an oil well, 1 into mosquito repellent solution, another into manure pit. The patients who could not survive had severe airway obstruction, which was difficult to clean and made the problem deteriorated progressively. One of the patients was sent to a hospital 3 days after the accident and another case developed fungal infection, pneumothorax and finally respiratory failure.

CONCLUSIONBAL through bronchoscopy is necessary for children who accidentally inhaled liquid and powdery materials. This treatment is safe and effective in diagnosis and treatment of such problems in children. The effect of treatment is influenced by types of inhaled material, the time of lavage clearance through bronchoscopy, and certain complications, such as infection etc.

Objective To investigate the psychologic status of irritability, depression and anxiety in patients who underwent intrauterine insemination (IUI) and to provide mental nursing care. Methods This study included 120 infertile patients who underwent IUI treatment from August 2008 to September 2009 in infertility clinics. All patients were divided into two groups randomly and assessed with the Irritability,Depression and Anxiety Scale (IDA). The 60 patients in control group were treated according to the standard IUI procedure, while the patients in study group were given mental nursing additionally. IDA scores before and after psychological intervention and clinical pregnancy rate were compared between the two groups. Results The IDA scores decreased obviously after mental nursing in study group (P ＜0.05 ). The clinical pregnancy rate per cycle was much higher in study group than that in control group ( P ＜ 0.05). Conclusions IDA can be applied to the psychological investigation of IUI patients. Efficient mental nursing care is beneficial to the success of IUI.

OBJECTIVETo assess the feasibility of the 10 microg recombination yeast hepatitis B vaccine in the expanded applicable population group aged 5 - 18.

METHODSPeople with both HBsAg and anti-HBs negative were selected to take two-stage clinical experiment and the safety and immunogenicity were observed. Safety observation was conducted in 925 subjects, while 568 for immunogenicity. The observation group (aged 5 - 18) included 493 subjects, and (age > 18) 75 enrolled in control group. For the observation group, there were three sub-groups including a child group (141, aged 5 - 6), early youth group (177, aged 12 - 13), and youth group (175, aged 16 - 18). Both groups were administered with 10 microg recombination yeast hepatitis B vaccines with 3 doses at 0 month, 1st month, 6th month. To assess the immunogenicity, the vaccination reactions were observed during the following 4 weeks in order to assess the vaccine safety. The blood samples were taken during 4 - 6 weeks after fully vaccinated, and then anti-HBs were tested with RIA and analyzed by comparing the positive rate of anti-HBs, the geometric mean titer (GMT) and the protective rate between the two groups.

RESULTSBoth observation and control group didn't show any general reactions, adverse events following immunization (AEFI) or coincidental cases when observed at 0.5 h, 6 h, 24 h, 48 h, 72 h, 1 week, 2 weeks, 3 weeks, 4 weeks after being vaccinated. The result of serum test showed, the positive rates of child group, early youth group, youth group and control group were respectively 100.00% (141/141), 97.18% (172/177), 98.29% (172/175) and 89.33% (67/75); the GMTs of anti-HBs were respectively 440.28, 875.38, 467.80, 131.06 U/L; the protective rates were respectively 100.00% (141/141), 97.18% (172/177), 97.14% (170/175) and 86.67% (65/75). The positive rate, GMT and protective rate of the experimental group were all higher than that of control group (chi(2)(positive rate) = 12.77, 5.12, 7.99; t(GMT) = 3.89, 4.13, 5.91; chi(2)(protective rate) = 16.81, 8.60, 8.44; P < 0.05).

CONCLUSIONThis vaccine could be expanded to 5 - 18 year-old population with safety and effectiveness, the positive rate and protective rate of anti-HBs were both higher than that of control group.
