OBJECTIVETo compare two kinds of method for treating lumbar tuberculosis with psoas abscess, to provide reference for clinical reasonable select of therapy treatment.

METHODSFrom January 2010 to January 2013,42 patients with lumbar tuberculosis combined with psoas abscess with obvious surgical indications were enrolled, including 24 males and 18 females with an average age of (38.5 ± 10.2) years old ranging from 21 to 63 years old. All patients were followed up for 18 to 24 months with an average of 20.9 months. Twenty-two patients underwent posterior vertebral body lesions cleared, bone graft fusion and internal fixation and percutaneous puncture catheter drainage for treatment of psoas major abscess as group A, and twenty patients underwent one-stage extraperitoneal approach to remove abscess, posterior vertebral body lesions cleared, bone graft fusion and internal fixation as group B. The operative time, loss of blood, length of hospital stay, clinical cure rate and other clinical results for the two groups were analyzed and compared.

RESULTSThe loss of blood was (452.3 ± 137.6) ml in group A and (603.5 ± 99.6) ml in group B, there was significant statistical difference (P < 0.05). The time of operation was (193.6 ± 91.2) min in group A and (230.5 ± 56.6) min in group B, there was significant statistical difference (P < 0.05). The time of operation and the loss of blood in group A were obviously less than which in group B. In group A 20 cases were cured and 2 cases relapsed, 19 cases were cured and 1 case relapsed in group B, there was no significant statistical differences between two groups regarding cure rate with chi-square test (χ² = 0.000, P = 1.000). All patients in two groups obtained good clinical curative effect. There were no significant statistical difference between two groups regarding for length of hospital stay with t-test (P > 0.05).

CONCLUSIONLumbar spinal tuberculosis with psoas abscess is not absolute indications for anterior open operation. Compared with the combined anterior and posterior surgical procedure, the percutaneous puncture catheter drainage combined with posterior debridement, interbody fusion and internal fixation can achieve the same clinical effect but less trauma for the patients.

Objective To analyze the application of recombinant gp125 proteins in serological diagnosis of nasopharyngeal carcinoma (NPC). Methods B cell epitopes of EBV gp125 protein were forecasted by internet server and the peptides were synthesized and coated to microplate for the detection of EBV-IgA antibody in NPC patients and healthy donors by ELISA. Results Six peptides were synthesized, wherein two showed low specificity and others displayed significantly higher positive rate in the NPC group than in the healthy group (P <0.001). Conclusion The BALF4 gene peptides are successfully synthesized and epitopes with high specificity and strong immunogenicity are screened for the preparation of gp125 antigen with high specificity and sensitivity.

OBJECTIVE:To improve the management on drug supply in our hospital by using the Six sigma method. METHODS: The quality control of the management on drug supply is achieved by practicing the five steps of Six sigma: concept, measurement, analysis, improvement and control. RESULTS & CONCLUSIONS: Six sigma method did effectively bring down the defect rate of drug supply from 6.66% before the introduction of the method to 0.59% after and raise the degree of satisfaction to the work of medicine provision from 80% before the introduction of the method to 95% after.

Stand-by training is an important step for a medical contingent to realize medical support in peacekeeping operations.In line with Draft MOU and General Guidelines for Peacekeeping OPNS,we need to shape a feasible standby training blueprint,and make the training plan for the medical contingent as a whole with consideration of tasks on our contingent and the actual situation of our army.

The establishment of emergency medical rescue contingent is required by the current situation of militarized disaster rescue as well as by the extension of the army's missions and responsibilities in the new era.In view of the experience in the training for the preparation against war,the authors approached the establishment of the emergency medical rescue contingent in the hospital in the following aspects:preliminary organization,function identification,module formation,equipment provision,and special training.

Objective:To determine the inflammatory factor levels and inflammatory cell percentages in the patients with cough variant asthma (CVA ), and to clarify their potential role in the pathogenesis of CVA unresponsive to bronchodilator treatment.Methods:60 patients with CVA were randomly selected and divided into CVA unresponsive to bronchodilator treatment group (n=30)and CVA responsive to bronchodilator treatment group (n=30).As the same time 30 cases of healthy persons were used as normal control group.The levels of interluekin-8 (IL-8)and esoinophil cationic protein (ECP)in their induced sputum were detected,the classification of inflammatory cells in their induced sputum were observed, and their scores of cough symptom were recorded. Results:The IL-8 level in the induced sputum of the patients in CVA unresponsive to bronchodilator treatment group was higher than that in CVA responsive to bronchodilator treatment group and normal control group (P<0.05).The ECP level in the induced sputum of the patients in CVA unresponsive to bronchodilator treatment group was lower than that in CVA responsive to bronchodilator treatment group (P<0.05),but it was similar to the level in normal control group (P>0.05).The neutrophil percentages in the induced sputum of the patients in CVA unresponsive to bronchodilator treatment group were higher than those in CVA responsive to bronchodilator treatment group and normal control group (P<0.05).The scores of cough symptom of the patients in CVA unresponsive to bronchodilator treatment group was positively correlated with IL-8 level (r=0.764,P<0.01), and the scores of cough symptom of the patients in CVA unresponsive to bronchodilator treatment group was positively correlated with the neutrophil percentage in induced sputum (r=0.889,P<0.01).Conclusion:IL-8 and neutrophil may be associated with the incidence of CVA unresponsive to bronchodilator treatment. They can aggravate the inflammation and hypersensitivity of airway and cough symptom. The determination of IL-8 and neutrophil can be used as an accessory method in the diagnosis and j udgement of severity degree and curative effect of CVA in clinic.

Aim To investigate the proliferation of HSCs stimulated by exogenous TGF-β1 (transforming growth factor betal),observe the effect of TFB(total flavonoids of Bidens Bipinnata L.)on smad2/7,typeⅠcollagen mRNA and protein expression of HSCs and study the protective effect and molecular mechanism of TFB on hepatic fibrosis.Methods HSCs were isolated with collagenase Ⅳ perfusion in situ and density gradient centrifugation. The effect of TFB on cell proliferation was observed by MTT colormetric assay. The auto-secretion of TGF-β1 and synthesis of type Ⅰ collagen were measured by enzyme-linked immuneadsordent assay (ELISA).Moreover,the expression of smad2/7, typeⅠcollagen mRNA and protein was measured by semi-quantitative RT-PCR and Western blot methods respectively.Results TFB could markedly inhibit the proliferation of HSCs of liver fibrosis rats stimulated by TGF-β1 and production of TGF-β1 and type Ⅰ collagen.In addition,TFB treatment could significantly down-regulate smad2 and type Ⅰ collagen mRNA expression and up-regulated smad7 mRNA expression of HSCs Smad2 protein expression of HSCs stimulated by TGF-β1 was also down-regulated by TFB.Conclusion TFB has the protective effect against hepatic fibrosis by inhibiting the activation of TGF-β1 signaling pathway and suppressing the HSC proliferation.

Aim To explore the therapeutic effect of total flavones of Bidens Bipinnata L (TFB) on liver fibrosis in rats and its mechanism. Methods The model of rat liver fibrosis was adopted which was induced by CCl4 injection. The effects of TFB were observed on the levels of serum HA,PCⅢ,CIV and Hyp in rats liver fibrosis,and on liver histopathological changes as well as collagen hyperplasia formation in liver tissue. The apoptosis of HSC were detected by double-staining of ?-smooth muscle actin (?-SMA) and TUNEL. The study in vitro was carried out on the culture of isolated hepatic stellate cells. Cell proliferation was detected with MTT assay. Cell apoptosis was detected by electron microscopy and flow cytometry. Results TFB can significantly reduce serum HA,PCⅢ,CⅣ and Hyp contents in liver fibrosis of rats,improve the liver pathologic injury,reduce collagen hyperplasia in liver of liver fibrosis rats,inhibit the activation and proliferation of HSC,and promote the apoptosis of HSC. In addition TFB could significantly inhibit the proliferation and increased the apoptosis of isolated and cultured HSC compared with the control group. Conclusions TFB has a significant therapeutic effect on the liver fibrosis rats,probably its inhibition of proliferation and stimulation of activated HSC apoptosis may be an important mechanism of its therapeutical effect against liver fibrosis.

Aim To observe effects of Seabuckthorn fatty acids on old rat ovarian granulosa cell apoptosis and expression of bcl-2 and fas,then discuss the adjustive effect of Seabuckthorn fatty acids on ovarian function of menopause.Methods 22 months old rats were randomly divided into 5 groups,estrogen control group,old control group,Seabuckthorn fatty acids group of high dose,middle dose and low dose.In addition,one young control group was made up of 3 months old rats.Rat ovarian granulosa cell apoptosis was detected by TUNEL.The expression of protein bcl-2 and protein fas were detected by immunohistochemistry,and bcl-2 mRNA and fas mRNA by in situ hybridization(ISH).Grey analyse was done using Q550CW image analyse system.Results Compared with the old rats control group,Seabuckthorn fatty acids of high dose,middle dose and low dose can differently restrain rat ovarian granulosa cell apoptosis,enhance the expression of protein bcl-2 and bcl-2 mRNA,weakened the expression of protein fas and fas mRNA.Conclusion Seabuckthorn fatty acids restrains ovarian granulosa cell apoptosis through adjusting the expression of bcl-2 and fas.Sequentially,it adjusts estrogen level and treats menopause syndrome.
