Objective To research the infections of respiratory syneytial virus(RSV)in children with respiratory tract inflammation and define its molecular epidemic features in Urumchi.Methods SamDles were collected from November 2006 to April 2007 in the People's General Hospital of Xinjiang Uygur Autonomous Region,including 112 respiratory secretions and 280 nasopharyngeal swabs. RSV and its subgroups were detected by nested PCR.The five positive amplicons selected randomly from all positive samples were sequenced and compared with other RSV in GenBank by BLAST and DNAStar.Results of all 392specimens.68 RSV G gene segments were tested.Among them,RSV lineage A occupied 93.3%,while B occuDied 6.7%.The identities between them were 63.1%-99.4%.Phylogenetic analysis defined that they belonged to two different clusters.Conclusion RSV was one of the important viruses leading to children's respiratory tract infections in the People's General Hospital of Xinjiang Uygur Autonomous Region during winter and spring from 2006 to 2007.RSV subtype A was the prevalent genotype in the hospital dunng this epidemics.

Heat shock protein 27 ( HSP27 ) is an endogenous protein that plays an important role in a great variety of physio-logical and pathological processes. It can express a large number under body stress conditions. Recent studies have shown estro-gen upregulates the expression of HSP27 through a number of ways, playing a perfect “triple protection” role. In the early stage of atherosclerosis, estrogen induces the phosphorylation of HSP27 via PI3K/Akt signaling pathway. Phosphorylation of HSP27 can resist the injury of vascular endothelial cells( VECs) through an antioxidant and anti-apoptotic pathway as well as the inhibition of cytochrome C. In the stage of forming foam cells, estrogen induces the expression and release of HSP27 from mac-rophages by stimulating the estrogen receptor β ( ERβ) , then HSP27 inhibits the LDL uptake and the release of proinflammato-ry cytokine by binding scavenger receptor A ( SR-A) . During the proliferation and migration of vascular smooth muscle cells ( VSMCs) , estrogen induces estrogen receptor α ( ERα) and protein phosphatase 2 ( PP2A) to form a complex that enhances the activity of PP2A, then it can lead to the dephosphorylation of HSP27 and finally inhibit cells proliferation and migration. In summary, the anti-atherosclerotic effect of estrogen is closely re-lated to the role of HSP27. Given the side effects of estrogen re-placement therapy( MHT) , regulating HSP27 may provide a no-vel therapy for the prevention and treatment of cardiovascular dis-eases in menopausal women clinically.

Objective:To observe the clinical efficacy of Yi Jin Jing (Sinew-transforming Qigong Exercises) for primary osteoporosis in the elderly.Methods:Eighty old patients with primary osteoporosis were randomized into a Yi Jin Jing group and a medication group,40 cases in each group.The Yi Jin Jing group was intervened by Yi Jin Jing (Sinew-transforming Qigong Exercises) training,while the medication group was intervened by oral administration of alendronate sodium tablet.Prior to and after 6-month intervention,the bone mineral density (BMD) of the proximal femur,visual analog scale (VAS) and activities of daily living (ADL) were estimated.Results:There were no significant differences in the BMD of the proximal femur,and VAS and ADL scores between the two groups before the intervention (P>0.05).After 6-month intervention,the above items all improved significantly in both groups (both P<0.01);the improvements in VAS and ADL scores in Yi Jin Jing group were more significant than those in the medication group (P<0.01),while the between-group difference in the BMD of the proximal femur was statistically insignificant (P>0.05).Conclusion:Practice of Yi Jin Jing (Sinew-transforming Qigong Exercises) can effectively ameliorate the BMD in the elderly with primary osteoporosis,and it can reduce the pain and improve ADL,with a better general effect compared to oral administration of alendronate sodium tablet.

AIM: To analyze the composition, distribution and characteristics of the elderly primary ocular tumors.
METHODS: This was a retrospective study and all 504 cases with primary ocular tumors aged 60 years or older were collected in Shanxi Eye Hospital, during the year 2000- 2012. The onset age, location and pathological pattern were analyzed.
RESULTS: There were 346 cases of benign ocular tumors (68. 7%), and 158 cases of malignancy (31. 3%). Papillomas was the most common type of the benign with 83 cases (16. 5%), followed by a variety of inflammatory cysts and lesions with 69 cases ( 13. 7%) and 64 cases (12-7%) respectively. Among malignant tumors cases, eyelid basal cell carcinoma originated from epithelial was the most common with 72 cases (14. 3%), followed by skin appendages sources malignant tumors with 39 cases (7. 7%). Concerning the location of ocular tumors, there were 282 cases of eyelid tumor (56. 0%) occupied the first position followed by conjunctival tumor with 157 cases (31. 2%).
CONCLUSION: The prevalence and type of primary ocular tumor in elderly people are significant differences from the general population and children's, and the proportion of malignant tumors tended to increase along with the increase of age.

OBJECTIVETo explore the relationship between angiotensin converting enzyme (ACE) gene single nucleotide polymorphisms (SNP) and premature coronary heart disease (PCHD) patients with blood stasis syndrome (BSS).
METHODSrs4343, rs4293, and rs4267385 were selected at SNP from ACE gene. Allele and genotype were detected. Frequencies of allele and genotype were compared by using time-of-flight mass spectrometry technique (TOF-MS).
RESULTSCompared with the healthy control group, genotype of rs4293 and rs4267385 in ACE gene were similar, but there was statistical difference in polymorphisms and allele frequencies of rs4343 in the I and II group (P < 0.05, P < 0.01). The frequency of G allele was higher in the 3 groups than in the healthy control group (P < 0.05, P < 0.01). The relative risk analysis showed that the risk for PCHD occurrence in G allele carriers at rs4343 (GG +AG) was 3. 6 times the risk in non-G allele carriers (95% CI: 1.224-10.585, P = 0.02). There was also statistical difference in sex, age, TC, and TG after adjusted Logistic regression analysis (OR = 3.994, 95% CI: 1.230-12.974, P = 0.021).
CONCLUSIONThe polymorphism at rs4343 (G2350A) might be one of risk factors for PCHD occurrence, but not a predisposing factor for PCHD patients of BSS.

OBJECTIVETo study therapeutic effects of minimally invasive percutaneous plate osteosynthesis for the treatment of intertrochanteric femoral fractures of Evans III, IV in elderly patients.
METHODSFrom December 2007 to April 2010, 23 patients with intertrochanteric femoral fractures were reviewed. Among the patients, 11 patients were male and 12 patients were female,ranging in age from 62 to 90 years, with a mean of 72.8 years. According to Evans classification, 13 patients were type III and 10 patients were type IV. All the patients were treated with proximal femoral locking plate (minimally invasive percutaneous plate osteosynthesis, MIPPO) surgery.
RESULTSThe operative time ranged from 45 to 60 min, with an average of 50 min. The blood loss ranged from 60 to 100 ml, averaged 80 ml. All the patients were followed up,and the duration ranged from 9 to 18 months, with an average of 11 months. The healing time based X-ray ranged from 3 to 6 months, with an average of 4 months. According to hip scoring criteria evaluation: 18 patients got an excellent results, 5 good.
CONCLUSIONFor the treatment of intertrochanteric femoral fractures of Evans III, IV in elderly patients, MIPPO has advantages such as small trauma, reliable fixation, which has good clinical application.

Comparison studies of recombinant prourokinase(pro-UK) in various host cells,and expression vectors were carried out. Expression levels of vectors constructed in this study in different cell lines were compared. Mammalian cells expressing pro-UK were established. The levels of pro-UK expression in recombinant Namalwa, Vero and Sp2/0 cells are 200,12.5 and 50 IU/( 106 cells 24h). pro-UK purities separated by immunoaffinity chromatograph are above 90 %. Immunoabsorbent assay showed the ratio of pro-UK in CHO cells is lower than that from Vero and Namalwa cells. This study provide new host cells for pro-UK production.
