Objective To explore the clinical characteristics and effects of thrombolytic and anti coagulation treatment in over 70 year old patients with pulmonary thromb embolism(PTE). Methods The clinical findings, diagnostic techniques, effects of thrombolytic therapy and anti coagulation in 58 over 70 year old patients with PTE were analyzed retrospectively. Results Deep venous thrombosis (DVT) in lower limbs (74 1%) was the most common thrombolism prone factors in our study. Limitation of movement and long term stay in bed due to a variety of causes were in the next place. The clinical findings were atypical, associated with a false diagnostic ratio of 46 5% in elderly patients with PTE. Undefined causal and different degree of dyspnea along with sudden and persistent hypoxemia were the main characteristics. Spiral CT and radioactive nuclear ventilation perfusion scan were important methods for diagnosis of PTE with positive finding of 95 7% and 62 5%, respectively. The effective and cure rate of thrombolytic therapy combined with anti coagulation, anti coagulation and anti platelet therapy was 91 3%, 75 8%, 0 and 47 8%, 17 2%, 0, respectively. Conclusions The most common risk factors of PTE in the elderly was DVT and the long term stay in bed or stay without active moving. The clinical symptoms were not only atypical but also variable. Thrombolytic with anti coagulation therapy is safe and effective, but anti platelet coagulation alone is not benefit.

The compound that distributes in the herbs with one common effect was named as "co-effect compound" (CEC). The CECs of three traditional Chinese medicine(TCM) effects, purgative, relieving pain and clearing heat, had been found and studied. A strong corresponding relationship was found between the pharmacological activities of CECs and the TCM effect they belong to. The study shows that it may be a feasible method to connect traditional effect of TCM with modem pharmacological activity.

Objective To explore the effect of fluoride and arsenic pollution on bone metabolism in exposed population. Methods One hundred and fifty-two fluoride and arsenic exposed people were selected from Jiaole village, Yuzhang town, Xingron county, Guizhou province in 2006, and 59 not exposed people from Daguoduo village 13 km away from Jiaole village were selected as control. Urinary fluorine(UF), urinary arsenic (UAs), urinary hydroxyproline (UHYP), cross-linked N-telopeptides of type I collagen (UNTX) and bone strength index(STI) were detected. Results The main effect of fluoride on UHYP and UNTX were statistically significant (F = 9.785, 4.225, P < 0.01 ), but was not significant on STI(F = 0.183, P > 0.05). The main effect of arsenic on UNTX was statistically significant (F = 2.660, P < 0.05 ), but was not significant on UHYP and STI(F = 2.012, 0.183,all P > 0.05). The interaction between fluoride and arsenic on UNTX was statistically significant (F= 2.429, P <0.01), but was not significant on UHYP and STI(F= 1.218, 1.001, all P> 0.05). Conclusions Fluoride exposure can affect the metabolism of collagen and bone resorption, and Arsenic exposure main affect bone resorption, fluoride and arsenic co-exposure have more significant effect on bone resorption. UNTX may be used as biological biomarker of bone metabolism for population co-exposed to fluoride and arsenic in health monitoring.

As a depot drug delivery system, injectable polylactide-polyglycolide (PLGA) sustained-release microspheres have been successfully used to treat many diseases since the first microsphere product Lupron depot was approved for marketing in the United States in 1989. It has the ability of long-term release in the body for several days to several months, which can not only reduce the times of administration, but also reduce the drug blood concentration fluctuations, significantly improve the safety and patient compliance. In vitro-in vivo correlation (IVIVC) makes the development of microspheres more possible. It can describe the dynamic information of drug release in vivo through the in vitro release behavior of microspheres, and can reduce the workload of each stage and shorten the time span while characterizing the performance of microspheres. IVIVC can provide guidance or support for drug development, production changes, supervision and management. This article summarizes the release mechanism of injectable PLGA sustained-release microspheres, common measurement methods and theories of in vitro and in vivo release. And we also focus on the establishment and application of IVIVC, especially A level IVIVC in the field of microsphere preparations, to provide a reference for further study on in vitro-in vivo correlation of microspheres.

Objective To define the stages of medical rescue after earthquake or tsunami disaster and their significance.Method Three stages of medical rescue were defined according to the clinical features of diseases in 3-37 days after earthquake or tsunami in Pakistan and Indonesia.The classification of diseases was based on the criteria of disaster medical rescue set by World Health Organization.Five diseases including injuries/wounds,acute upper respiratory tract infection,acute hemorrhagic enterocolitis,acute enterecolitis and other diseases of internal medicine except epidemic or suspected epidemic diseases were employed to define the stages of disaster medical rescue.Results Injuries/wounds mainly occurred in 6 days after disaster.The incidences were 61.45% to 79.52% and 61.48% to 72.35% in Pakistan and Indonesia,respectively.The incidence of acute upper respiratory tract infection reached to a considerably high rate one week after disaster.Other diseases usually appeared one week later with incidence of 33.93% to 71.11% and 31.50% to 52.11% in Pakistan and Indonesia,respectively.The rate of acute hemorrhagic enterocolitis was 2%o in Indonesia whereas 35‰of acute enterocolitis was found in Pakistan.Conclusion Three stages of disaster medical rescue could be well defined.(1)Early or critical stage(in 6 days after disaster):Treatment of injuries/wound and resuscitation was the primary step to deal with.(2)Intermediate of subaeute stage(7-30days following disaster):The incidences of various kinds of diseases increased and more medical resources were needed in order to treat the upper respiratory tract infection and to lower the disable rate,and to prevent the prevalence of epidemic diseases.(3)Later or recovery stage(1-3months after disaster):The general condition of victims became even better than that of those affected by commonly occurred local diseases,and during this period,there were shortages of medical facilities and medical personnel.Therefore,supplement of medical resources was required.The well defined stages of medical rescue have an important significance for medical rescue teams to treat victims and prevent epidemic diseases more efficiently and timely,and also provide a guidance of scientific basis for the logistics officers of local government as well as our government to make a proper and reasonable distribution of medical resources,and dispatch and arrangement of medical rescue teams.This guidance also helps to make victims re- reliant.

Objective To explore the current status of the family function and the influential factors in the community, Methods A questionnaire survey including the general data questionnaire and APGAR scale developed by Smikstein was conducted in 94 families of three communities of Wuhan City. Results 46.8% of the surveyed family showed good function, 51. 1% showed moderate dysfunction and 2.1% in severe dysfunction. The multinomial regression revealed that education level and whether the family members had chronic diseases had influence to the family function level (P<0.05). Conclusions More than 50% of the families exist moderate or severe family dysfunction. The higher education level, the better family function; meanwhile compared with the family whose members experience chronic diseases, the family without experiencing chronic dieseases shows much better family function.
