OBJECTIVETo discuss the application and clinical effect of damage control concept in the treatment of severe limbs fractures combining with multiple trauma.

METHODSFrom July 2009 to July 2012, 30 patients with severe limbs fractures combining with multiple trauma were treated with the damage control concept, included 20 males and 10 females with an average age of (34.03 ± 12.81) years old ranging from 20 to 60 years old; the ISS averaged (35.00 ± 12.81) points (ranged from 26 to 54 points). And the control group also contained 30 patients with severe limbs fractures combining with multiple trauma treated by the traditional operation from June 2006 to June 2009, there were 23 males and 7 females with an average age of (34.23 ± 11.04) years old ranging from 18 to 65 years old. The ISS averaged (35.56 ± 11.04) points (ranged from 26 to 51 points). The age, gender, ISS, Gustilo classification, operation time, intraoperative blood loss, blood transfusion,postoperative complications and mortality rate were observed and compared.

RESULTSIn the damage control concept group,there were 28 cases surviving and 2 cases (6.7%) death; 6 cases of postoperative complication included 2 cases of adult respiratory distress syndrome, 1 case of multiple organ failure, 1 case of disseminated intravascular coagulation and 2 cases of wound infection. In the control group, there were 22 cases surviving and 8 cases death(26.7%); 13 cases of postoperative complication included 4 cases of adult respiratory distress syndrome,2 cases of multiple organ failure, 2 cases of disseminated intravascular coagulation and 3 cases of wound infection. There were no statistically significant differences between two groups in age, gender, ISS, Gustilo classfication and complication (P > 0.05), however there were statistically significant differences in mortality rate, operation time, blodd loss, blodd transfusion between two groups (P < 0.05).

CONCLUSIONDamage control concept is used to treat severe limbs fractures combining with multiple trauma which has the rapid and effective therapy, can improve survival rate and reduce complication.

Resveratrol, as a natural polyphenolic compound, has a wide range of beneficial effects, which includes anti-tumor, cardiovascular protection, anti-oxidant and estrogen-like effects, and so on. Its various physiological properties are closely related to the therapeutic principle for prevention and treatment of high altitude hypoxia injury. Resveratrol may play an important role in relieving or curing high altitude diseases, especially high altitude polycythemia(HAPC). However, the literature about study and application of resveratrol in plateau medicine field is rarely reported up to now. In this review, we summarized the physiological effects of resveratrol, discussed the possible main principle of resveratrol for HAPC therapy, and looked forward to resveratrol's perspective or potential application in high altitude medicine.

Chronic osteomyelitis is one of the most common disorder in clinic. In recent years due to diabetes, peripheral vascular disease and trauma induced disease increased, the prevalence rate increased. With the development of magnetic resonance imaging and CT imaging technology, it greatly improved the accuracy of clinical diagnosis of chronic osteomyclitis and ability to describe the infection characteristics, and provide a reliable basis for clinical treatment. The current research on chronic osteomyelitis mainly concentrated on the aspects of imaging applications and ways of using antibiotic optimization control inflammation, defect restoration and reconstruction of blood supply and treatment. But the best time to the antibiotic therapy and the use of program is still uncertain, for after debridement, bone grafting time and defect repair function of fast recovery still need further research.

OBJECTIVETo observe effects of serum Bushen Huoxue prescription(Chinese characters) on classic Wnt/β-catenin signaling pathways of osteoblasts, and explore mechanism of Bushen Huoxue prescription (Chinese characters) for preventing osteoporosis.

METHODSTwenty health female rats were randomly divided into two groups, including Bushen Huoxue (Chinese characters) group and saline group,10 in each group. Bushen Huoxue (Chinese characters) group and Saline group were gavaged Bushen Huoxue and saline every day for 1 week. Bushenhuoxue containing serum and saline containing serum were got according to methods of serum preparation of drug-containing. The osteoblasts was cultured with neonatal rat skull according to Enzyme Consumer Law, and was identified by Wright-Giemsa staining (R-J) and alkaline phosphatase staining (ALP). The third generation of osteoblasts was divided into three groups, including saline group, normal group,Bushen Huoxue (Chinese characters) group. Each group were added to 15% appropriate medium. ALP activity of osteoblasts and osteoblasts proliferation rate were tested, mineralized nodules were observed, the expression of β-catenin, Runx2, Osx mRNA of osteoblasts were tested by RT-PCR.

RESULTSThere was blue granules in cytoplasm, cell nucleus was flint with 1 to 3 nucleoli showed by R-J staining, morphology of osteoblasts were cultured. ALP staining showed cytoplasm with purple granules, the results showed that the cultured cell was osteoblasts. The content of ALP in Bushen Huoxue (Chinese characters)group was (6.272±0.131) ,appreciation rate was (0.81? 0.172), and could significantly improve differentiation and proliferation activity of osteoblasts compared with Saline group (P< 0.01). There were four different size orange nodules, the Maximun nodule was 1.0 x 1.0 cm in Bushen Huoxue (Chinese characters) group after Alizarin red staining, the results showed Bushen Huoxue (Chinese characters)group could obviously improve mineralization of osteoblasts. The expression of mRNA of β-catenin, Runx2 and Osx in Bushen Huoxue (Chinese characters)group were (1.782±0.944), (1.935±0.994) and (1.610±0.811) by RT-PCR,it was significantly increased compared with saline group (P<0.01), but there was no difference between Bushen Huoxue (Chinese characters)group and normal group (P>0.05).

CONCLUSIONBushen Huoxue (Chinese characters)group could obviously promote differentiation, proliferation and mineralization of osteoblasts through activation of Wnt, β-catenin signaling pathway. It suggested that the mechanism of action of Bushen Huoxue (O'f f Il.t)particle clould prevent osteoporosis through the activation of Wnt, β-catenin signaling pathway.

OBJECTIVETo establish the steriod-induced osteoporosis model with the type of Kidney-Yin deficiency.

METHODSTotally 45 female Kunming mice were randomly divided into normal group,model group and Liuwei Dihuang pills(Chinese character: see text)group. The model was established by intramuscular injecting of Dexamethasone. Liuwei Dihuang pills (Chinese character: see text) group was administered orally with Liuwei Dihuang pills (Chinese character: see text). The signs and symptoms of mice were observed dynamically. All the animals were sacrificed at the end of the 6th weeks. The level of ACTH, cAMP, cGMP, TSH and E2 in serum were detected to evaluate deficiency of Kidney-Yin. Morphological changes and bone density were observed to evaluate osteoporosis.

RESULTS(1) Compared with control group, mice in model group appeared obvious Kidney-Yin deficiency symptoms, including hair dry, restlessness, excitability, hard stool, and yellow. (2) Compared with control group,the weight of mice in model group gained slower (P<0.01); the index of adrenal gland,liver and spleen decreased (P<0.01, P<0.01 ,P<0.01); the level of ACTH and TSH increased (P<0.01 ,P<0.01), the level of E2 decreased (P<0.01) and the ratio of cAMP/cGMP increased (P< 0.05). (3)Compared with control group,the bone density of lumbar vertebra and femur in model group were significantly decreased (P<0.01, P<0.05); HE staining revealed osteoporosis in model group mice. (4)However, the Liuwei Dihuang pills (Chinese character: see text) group can partly antagonize the inhibition of the HPA axis, alter the disordered sex hormone and the ratio of cAMP/cGMP, and reverse the osteoporosis partly.

CONCLUSIONthe model of osteoporosis with type of Kidney-Yin deficiency could be established by Dexamethasone intramuscular injection. With less interference, it wight be a stable and reliable modeling method for integration of disease and syndrome in TCM.

OBJECTIVE: To explore the relationship between polymorphism of apolipoprotein E (ApoE) exon 4 gene and different syndromes in patients with coronary heart disease (CHD). METHODS: Two hundred patients with CHD were divided into four groups according to syndrome differentiation, including syndrome of phlegm (PS), syndrome of blood stasis (BSS), syndrome of phlegm-blood stasis blocking (PBBS) and syndrome of non-phlegm and non-blood stasis (NPNBS). One hundred healthy volunteers were included in control group. Blood lipids were measured by routine examination. Total DNA of peripheral blood was extracted. ApoE genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. All data were analyzed by SAS software. RESULTS: (1)The occurrence rate of epsilon4 allele of ApoE in patients with CHD was 19.5%, significantly higher than 9.5% in the control group (P<0.05), and the E 3/4 genotype was especially more frequent (P<0.01). (2) The levels of total cholesterol (TC), total triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) in patients with epsilon4 were higher than those in patients without epsilon4 (P<0.01). (3) The frequencies of epsilon4 allele and E3/4 genotype in patients with PS were significantly higher than those in patients with BSS (P<0.05). CONCLUSION: ApoE epsilon4 allele, especially E3/4 genotype, is the risk factor of CHD. There is a relatively close relationship between patients with ApoE epsilon4 allele and PS. It may be one of the main susceptible genes in CHD patients with PS.
