It is still controversial whether or not the severe pneumonia is associated with heart failure in children.Currently,we pay more attention to the pathophysiological procedure of heart failure,such as pneumonia complicated with respiratory failure,shock and myocardial injury.Pay attention to the cardiopulmonary interaction mechanism and systemic inflammatory response.According to different pathophysiological mechanisms,guide the treatment by monitoring the hemodynamic status.

Occupational health literacy （OHL），as an important component of improving national health literacy，is a contributing factor affecting the health of the occupational population. OHL refers to the ability of individuals to gain， understand，and use occupational health information for keeping their own health and promoting group health. OHL competence includes three levels，namely basic competence，information processing competence，and occupational health promotion competence. At present，some domestic and foreign scholars used OHL assessment tools or developed new assessment tools to meet the characteristics of different populations for OHL assessment. Some scholars combined several dimensions for OHL measurement in terms of cultural background，occupational characteristics such as working environment，work behaviors，safety and health training，and added occupation-related dimensions to conduct OHL evaluation. However，it is difficult to obtain reliable results by only relying on one single scale to evaluate the health literacy of various occupational groups. At present， domestic and foreign researches have investigated the intervention of occupational health promotion and its effects，but the relevant literature on OHL intervention based on OHL assessment results of occupational population is relatively limited. In order to meet the requirements of the changing new pattern of occupational health practice，further studies are needed for theoretical research of OHL connotation and denotation，OHL measurement methodology，and OHL intervention strategy.

There are many problems about multiple breast cancer (MBC),such as whether it results from intramammary spread of a single tumor, or from two or more separate neoplastic events? Whether MBC has inferior outcome compared with unicentric lesions? Whether MBC is suit for conservative surgery and the sentinel lymph node biopsy, and so on. Thus: We reviewed the prospect for diagnosis and therapy of MBC.

Atrial fibrillation is an important cause of ischemic stroke.Studies have shown that the acute ischemic stroke patients with atrial fibrillation may have more severe neurological deficits and higher mortality compared with those without atrial fibrillation.In addition,atrial fibrillation is also an independent risk factor for the failure of recanalization after iotravenous thrombolysis,and it is associated with poor outcome.Mechanical thrombectomy treatment provides a new therapeutic regimen for acute ischemic stroke patients with atrial fibrillation.This article reviews the intravenous thrombolysis and mechanical thrombectomy for acute ischemic patients with atrial fibrillation.

ObjectiveTo observe the therapeutic efficacy of warm needling plus Chinese medicinal fumigation and rehabilitation training in treating post-stroke shoulder pain.MethodSixty eligible patients were randomized into a treatment group (warm needling plus Chinese medicinal fumigation and rehabilitation) and a control group (rehabilitation training), 30 casesin each group. The Visual Analogue Scale (VAS), Fugl-Meyer Assessment Scale (FMA) and Barthel Index (BI) were respectively used to evaluate pain intensity, upper-limb motor function and activities of daily living, and the clinical efficacies were compared between the two groups.ResultAfter 30-day treatment, the improvements of shoulder pain intensity, upper-limb motor function and activities of daily living in the treatment group were more significant than that in the control group (P<0.05). There were no adverse events happened in the two groups.ConclusionWarm needling plus Chinese medicinal fumigation and rehabilitation training can effectively and safely mitigate shoulder pain, improve upper-limb motor function, and enhance the activities of daily living, and its therapeutic efficacy is superior to that of the control group.

ObjectiveTo study the relationship between vitamin D receptor (VDR) gene polymorphism and calcitonin receptor (CTR) gene polymorphism, and bone mineral density (BMD) of the Han nationality woman in Hebei, explore the pathogenesis of osteoporosis (OP) at the gene level.MethodsPolymorphisms of VDR gene and CTR gene were analyzed by restriction fragment length polymorphisms (RFLPs) in 60 Han nationality women in Hebei.ResultsBb genetype of VDR had lower BMD values at all sites which were measured compared with bb genetype (P<0.05); CC genetype of CTR had tendency for lower BMD values at the L1～L4 compared with CT genetype (0.05

Objective We studied the expression of VEGF and its receptor,FLK－ 1,in neuroblastoma and its relation to clinical features.Methods With the help of antigen repairing,immunohistochemical analysis using antibody against VEGF,FLK－ 1 was carried out on speciments of 52 cases of neuroblastoma.Results There were 36 cases of VEGF and 34 cases of FLK－ 1 positive expression,the expression of them were nearly consistent.The positive rate of VEGF and FLK－ 1 were higher in metastatic tumors(28/34,26/34)than in non－ metastastic tumors and had statistical significance(respectively P<0.01,P<0.05).The expression of VEGF in UH tumors was higher than in FH tumors,and statistical value is significant(P<0.05).Conclusion VEGF is a vital angiogenic factor,and may play an improtant role in the progression and metastasis of neuroblastoma.Its expression and function correlates well to FLK－ 1,and may aid in predicting patients at risk of metastasis.

Objective To approach the alleviating effect of medicative diet for food therapy on hepatic function of patients with gastric cancer and adjuvant chemotherapy after operation and supply references for effective treatment and nursing. Methods We divided 123 patients with gastric cancer after operation into the test group (65 cases) and the control group (58 cases).The control group adopted routine treatment project while the test group received medieative diet for food therapy based on routine treatment project. The changes in hepatic functions were compared between the two groups. Results The changes in hepatic functions of the test group were better than those of the control group (P<0.01 ). Conclusion Medicative diet for food therapy could significantly restore the seriously damaged hepatic function after chemotherapy.

Objective To investigate the effect on ER expression in MCF-7 cell by siRNA against survivin mediated by adenovirus vector.Methods An adenovirus vector of siRNA against survivin was constructed and used to infect MCF-7 cell.The change of expression of survivin and ER was detected by Western Blot.Results The expression strength of survivin are 0.09 ± 0.04、0.86 ± 0.08、0.82 ± 0.17;expression strength of ER are 1.57 ± 0.09、1.16 ± 0.10、1.23 ± 0.01 respectively in the experimental group,negative control group and blank control group.Statistics analysis shows that the adenovirus vector of siRNA against survivin constructed in the study can suppress the expression of survivin significantly,and suppress the expression of survivin can up-regulate the estrogen receptor (ER) expression.Conclusions The results suggest that there may be a certain regulatory mechanism between survivin and ER signal pathway in MCF-7 cell and siRNA against survivin is of important potential value in the endocrine therapy of hormone receptor positive breast cancer.
