Pulmonary edema frequently occurs after severe burn. It not only impairs pulmonary function directly, but also can induce or exacerbate other pulmonary complications such as lung infection, acute lung injury ( ALI), and ARDS. Extravascular lung water (EVLW) is closely related to the pulmonary edema. Dynamical monitor of EVLW has been used to predict and quantify the degree of pulmonary edema clinically. This review focuses on the recent progresses at home and abroad on the formation mechanism, monitoring approach, and prevention and treatment of EVLW after severe burn injury.

At present, the computer administration and network system for diabetes still need exploration in China. A management software for the prevention and treatment of diabetes has been developed, taking the advanced MS SQL SERVER system as background database, while PowerBuilder 9.0 as foreground development tool. Both personal version and net version are configurable at random. This software includes six parts, namely the general data of patients, conventional physical examination of patients, treatment proposal, knowledge management, data query and statistical analysis, and system maintenance, in which they contact and conjugate with each other for the convenience of the whole processing. Good effects are obtained in the practical application of this software, and a regional network of the preventive and therapeutic information for diabetes is set up combining with other medical units, which can share the individual information, improve the ability of cooperative and follow-up study of diabetes, promote the data transferring and diagnosing quality of primary medical services, and is beneficial for both patients and physicians.

Erlotinib,a kind of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs),has been effectively used in the treatment of non-small cell lung cancer (NSCLC).Although it prolongs patients survival time,erlotinib is limited to be further applied for its resistance.It has been proved that threonine to methionine mutations in codon 790 (T790M),Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation and the amplification of met oncogene play important roles in the drug resistance.Based on the different molecular mechanisms of resistance,multiple clinical trials of the second generation TKIs,retreatment of chemotherapy or erlotinib and subsequent treatment according to failure modes have been developed.

[Objective]To evaluate outcome of the treatment of unstable distal radius fractures in the elderly patient using a volar T-shape plate.[Method]From January 2001 to April 2003,42 cases with unstable distal radius fractures older than 60 years(range 60~75 years;mean age 65.1 years) were treated with a T-shape plate fixation.The fractures were classified according to the AO classification of distal radius fracture: 4 A2,7 A3,5 B1,3 B3,9 C l,11 C2,3 C3.Artificial bone graft substitutes were used in 28 cases with severe cortex destruction and insufficient buttress.[Result]All patients were followed up(mean 18.2months,range 12~24months).Final volar tilt was averaged 3.66? and radial tilt 20.1?,and radial shortening averaged 1.59 mm in 6 cases.Step-off or gap of the articular surface was found in 6 cases(mean

Objective To investigate the biosynthesis of arbutin by suspension culture of crown gall of transgenic Panax quinquefolium. Methods Hydroquinone in methanol(60 mg/mL) was added to the medium of the crown gall of P.quinquefolium after precultured for 20 d,then they were co-cultured for another 60 h.The product was isolated and purified by column chromatography and its structure was identified by physicochemical properties and spectroscopic data.The dynamic curve of biotransformation was investigated by quantative analysis of arbutin with HPLC.Results The product could be obtained from both of the culture and medium,which was isolated and elucidated as 4-hydroxyphenyl-?-D-glucopyranoside(arbutin).After co-cultured for 60 h,the mole conversion ratio of hydroquinone is 88.4%,the product contents in culture and medium are 63.69 mg/flask and 1.86 mg/flask,respectively,and the excretion ratio of arbutin reaches the highest(2.92%).Conclusion It's the first time around the world that the crown gall of transgenic P.quinquefolium is used as a biotransformation system and arbutin which shows varied pharmacological activites have been got successfully.

To investigate the chemical constituents of hemostatic extract of Pyrola calliantha H. Andres, the extract was subjected to chromatographic separation and purification. Along with some known compounds, a new naphthaquinone derivative was isolated and identified as 2-(1, 4-dihydro-2, 6-dimethyl-1, 4-dioxo-3-naphthalenyl)-3, 4, 5-trihydroxylbenzoic acid by physicochemical and spectroscopic analysis.
