Objective To investigate the relationship between serum growth hormone, C-peptide, blood lipids levels, blood glu-cose, hypertension and type 2 diabetes nephropathy. Methods 82 type 2 diabetes (including 40 without nephropathy and 42 with nephropa-thy) and 39 healthy objects were enrolled. BG,GH,C-P,HbAlc,TC,TG,LDL-C and HDL-C were detected. Results The results showed that the values of blood glucose in each time-phase and HbAlc in both type 2 diabetes groups were significantly higher than that in healthy objects. In type 2 diabetes nephropathy group, the serum levels HbAlc, FGH, TC, TG, LDL-C, systolic blood pressure and diastolic blood pressure were significantly higher than that without nephropathy and those healthy objects(P<0.01). C-P (Oh)and C-P (2h)in type 2 di-abetes nephropathy group was significantly lower than that without nephropathy and those healthy objects(P<0.01). In groups patients of type 2 diabetes nephropathy, the disease duration had significantly longer than patients without nephropathy (P<0.01). The results of cor-related analysis with Pearson showed that HbAlc was significantly positive correlated with FGH(r=0.912, P<0.01), HbAlc was signifi-cantly negatively correlated with C-P(0h)(r=-0.803, P<0.01)and HbAlc was significantly negatively correlated with C-P(2h)(r=-0.771, P<0.01). FGH was significantly positive correlated with TC (r=0.413, P<0.05). Conclusion These results suggested that type 2 diabetes nephropathy has persistent elevated levels of blood glucose and disorder of lipid metabolism. The elevated levels of FGH, hy-pertension and islet B cell secretion function deficiency are important risk factors for type 2 diabetes nephropathy.

OBJECTIVE: Based on the point of introducing novel analytical methods into the testing of implanted materials, this article will summarize the principle and development of those effective analysis technologies, and the applications in testing and evaluation of medical implantations.DATA SOURCE: We retrieved Medline database (http://www.isiknowledge.com/MEDLINE) from 1987 to 2009 and Wanfang database (http://www.wanfangdata.com.cn) from 1997 to 2009, with the key words of "implantation, analytical method, testing". A total of 75 literatures of original articles, review, commentary, exchange of experience, case report and meta-analysis were retrieved.DATA SELECTION: The literatures published in recent years with strong directions were included, and those in the same field published recently or in authoritative journals were used. The literatures of analytical syndrome method and application of implant material, or with repetitive and old contents, were excluded.MAIN OUTCOME MEASURES: Totally 75 literatures, including 29 Chinese articles and 46 English articles, were included.Following reading titles and abstracts, 30 articles of unrelated research objective, and 15 articles of repetitive content were excluded. Finally 30 articles were used, composing 6 reviews and commentaries and 24 original articles.RESULTS: The requirement of implantations are growing with the development of clinic technology, along with much more attentions have been paid on the testing and evaluation of implanted materials and products. Modern analytical technology should be introduced into testing of implanting materials, which could not only clarify the relations between structure and performance, but also standard the testing method and judge the failures in medical accident.CONCLUSION: Modern analytical technology plays an essential effect on detecting implantation materials and on failureanalysis of implantation products.

OBJECTIVE: In China, there are little literatures about nonspecific low back pain(NLBP) and no standardized diagnostic classification of it. This paper reviews the clinical and basic studies on NLBP, and discusses the clinical features and progress in related studies. It is necessary for rehabilitation and intervention of NLBP science norm.DATA SOURCES: Medline, China Wanfang, China Biomedicine (CBM),China Academy Journal(CAJ) and its VIP database.STUDY SELECTION: By searching "nonspecific" and"low back pain" for all data and information about NLBP, we obtained 163 English articles and 22 Chinese ones. These documents were further restricted by "in title" and "2000-2004" to obtain subject documents in the latest 5 years(28 English and 9 Chinese documents) . The main references of important documents were manually searched for full-text articles. Types of these documents were basic study, clinical study.DATA EXTRACTION: All the related information about NLBP in the full-text documents was classified and extracted.DATA SYNTHESIS:Low back pain is generally classified into 3 types according to the present clinical guidelines: NLBP, specific low back pain and sciatica. NLBP constitutes 85% of low back pain and its cause is not clear although it is related to many risk factors. Of the treatment methods for NLBP, all are selective ones.CONCLUSION: Standard classification of diagnosis of low back pain needs to be established to guide clinical practice. Prevention is better than treatment. Tertiary prevention combined with multidisciplines is a promising way to relieve pain and prevent recurrence and disability.

Objective To compare of pathogenic bacteria characteristics between praecox and tardus ventilator-associated pneumonia (VAP) in the elderly with critical illness,and to provide the guildline and evidence of clinical prevention and treatment. Methods The clinical data of 276 VAP patients aged (69.3 ± 5.3) years in our hospital were retrospectively analyzed.There were 97cases (35.14％) with praecox VAP,179 cases (64.86％) with tardus VAP.Vitek 32 system was applied to identify pathogenic bacteria. Results In patients with praecox VAP,105 pathogenic bacteria were isolated,among which 72 cases(68.57％) suffered from G- bacterium,21 cases (20.00％) from G+ and 12 (11.43％) from fungus. The most widely distributed pathogens were hemophilus (22.86％),streptococcus pneumoniae(14.28％ ) and staphylococcus aureus(14.28％).In the patients with tardive VAP,186 pathogenic bacteria were isolated including 117(62.90％) G- bacterium,54 (29.04％)G+ bacterium and 15 (8.06％) fungus; the most widely distributed pathogens were staphylococcus aureus (24.19％), pseudomonas aeruginosa (22.58％) and klebsiella pneumoniae (14.52％).The death rate of tardus VAP(24.58％) was significantly higher than of praecox VAP (10.31％ ) (x2 =8.14,P＜0.05).The durations in ICU and mechanical ventilation were much longer in tardus VAP[(10.3±4.2)d and (7.8±2.7)d] than in praecox VAP[(7.8±3.1) d and (3.7±1.1)d] (t=5.15,14.32,P＜0.05). Conclusions There is differences in pathogenic bacteria distribution between praecox and tardus VAP,and the prognosis of tardus VAP may be worse.
