Objective: To investigate the effect of early dexamethasone treatment on seawater immersion-induced acute lung injury after open chest trauma. Methods: Twenty-four animals were evenly randomized into three groups: control group (CG), seawater group(SG), and dexamethasone treatment group (DG). Animals in CG group only had open chest trauma, those in the SG group were exposed to seawater after open chest trauma, and those in the DG group were treated with dexamethasone (1 mg/kg) after exposed to seawater. The vital signs of animals, plasma osmotic pressure, lung permeability index (LPI), and peripheral white blood cell count were observed 0,2,4,6, and 8 h after trauma. The plasma samples and bronchoalveolar lavage fluid (BALF) were collected for testing the levels of cytokines (IL-1ß, IL-8, and vWF, etc.) with ELISA kit. H-E staining was used to observe the pathological changes of the lung. Results: Compared with the SG group, the pathological changes were improved in the DG group; the plasma osmotic pressures were similar between the two groups; and the pulmonary permeability index was markedly decreased in the DG group (0.039±0.006 vs 0.055±0.002, P<0.05). Besides,the count of peripheral leukocyte(X 109) and plasma IL-Iß, IL-8, and vWF(pg/ml) were all markedly decreased in the DG group compared with the SG group(WBC: 21.52± 3.21 vs 24.8±2.08; IL-Iß:72. 84±38.42 vs 131.90±35.39; IL-8:45.21± 16.39 vs 88.26± 6.66;vWF:0.47±0.08 vs 1.03± 0.09,P< 0.05). Conclusion: Early dexamethasone treatment can attenuate the inflammatory injury of the lung in dogs with open chest trauma after seawater immersion, providing more chance for further management.

To study tissue distribution of TTV in experimentally infected Rhesus monkey and if the TT virus is hepatotropic. Total DNA was extracted from tissues of 5 experimentally infected Rhesus monkeys. TTV was detected by PCR,and dot hybridization was done with virus double DNA strand probe or single antisense strand probe. The double strand probe was hybridized with DNA of liver, bone marrow, and spleen, stomach, small intestine, colon. and sera. In the above tissues , the virus was also positive as shown by PCR. The single strand antisense probe was only hybridized with DNA of liver, bone marrow,and small intestine of all 5 monkeys, but not with that of other tissues. It suggested that TTV could infect many tissues of Rhesus monkey. Only the liver ,bone marrow, and small intestine presented the virus positive single strand, which might be a replicative intermediate of the virus. It suggests that TT virus replicates in liver , bone marrow, and small intestine,and it might be hepatotropic.

OBJECTIVEE23K polymorphism in KCNJ11 gene is associated with cardiovascular disease and diabetes. In order to explore the mechanism of E23K correlation to related diseases, the effect of E23K polymorphism in KCNJ11 gene on membrane current was investigated.

METHODSThe exon of KCNJ11 was obtained by PCR amplification and the G-->A mutation was completed by overlap extension PCR. The sequences of KCNJ11 exon contained 23E or 23K was inserted into pcDNA3.1/CT-GFP vector respectively. The recombinant plasmid, pcDNA3.1-KCNJ11(E) and pcDNA3.1-KCNJ11(K), were transfected into HEK293T cells by lipofectamine and the membrane current density was determined by whole-cell patch clamp technique.

RESULTS1,173 bp sequences of KCNJ11 gene's exon were amplified by PCR and the recombinant expression plasmid, pcDNA3.1-KCNJ11(E) and pcDNA3.1-KCNJ11(K), were constructed successful. Positive and negative currents were detected in HEK293T cells transfected with difference plasmid by whole-cell patch clamp technique. Results showed that the reversed voltage was 50mV. The current in HEK293T cells with pcDNA3.1-KCNJ11(E) was significantly greater than that with pcDNA3.1-KCNJ11(K) (P < 0.05, n = 10).

CONCLUSIONThe polymorphism of E23K in exon of KCNJ11 gene changed the membrane currents in HEK293T cells. It could be an experiment support for the possible mechanism between the locus and related diseases.

To discuss the availability of evaluation on the dissolution studies of the multicomponents in traditional Chinese medicine, the in vitro dissolution of total composition of the tablet of rhizomes of Ligusticum chuanxiong components and its correlation with the in vivo were studied by the method of area under the absorbance-wavelength curve (AUAWC). Taken the tablet of rhizomes of Ligusticum chuanxiong components which is composed of sodium ferulate and ligustrazine hydrochloride as subject model, the dissolution tests were carried out with basket method. The plasma concentrations of tablets in different rats were determined by AUAWC at different interval times. The in vivo absorption percentage was calculated by Wagner-Nelson equation to evaluate the in vitro and in vivo correlation. According to the results, the cumulative dissolution in vitro of total composition of tablets of rhizomes of Ligusticum chuanxiong components at 60 min was 90.65% in water by AUAWC. The in vivo pharmacokinetics is fitted with an one-compartment model. The linear equation based on the cumulative dissolution rate (fr) and absorption percentage (fa) at 5, 10, 20, 30 and 60 min was fa = 0.819 7 fr+0.183 and the correlation coefficient was 0.959 5, which showed a good correlation between the in vitro dissolution and the in vivo absorption percentage. The method of AUAWC can be used accurately, feasibly and conveniently to evaluate the in vitro and in vivo correlation of total composition of tablets of rhizomes of Ligusticum chuanxiong components, which will provide better guidance to study the in vitro and in vivo correlation of sustained release preparation etc under complex system of traditional Chinese medicine in the future.

Objective By analysis oflateralepicondylitis patients MRI features to explore the lateralepicondylitis namedrationality and authorized its opinions for the ninth edition surgery textbook. Methods Cochrane's systematic review methods were used to retrieve the literature about lateralepi-condylitis patients MRI features fromCochrane Library, Medline, OVID, EMBASE, Chinese biomedical literature database (CBM), VIP, CNKI, Wan fang digital journals, and totally 31 articles were reviewed. 13 articles met the inclusion criteria for the lateral epicondyle of humerus elbow in patients with MRI findings. In accordance with the case-control data RevMan 5.0 software was used for Meta analysis withodds ratio (OR) as count data statistics. Interval estimation wasmade of 95% confidence interval (CI). When the datacannot be performed Meta analysis, only qualitative analysis was made. Results 13 studies met the inclusion criteria, including 315 ipsilateralelbows (5 patients with bilateral disease, 305 patients with unilateral disease) and 169 asymptomatic side of the elbow (98 cases of patients with the contralateral elbow, 71 cases of healthy volunteers). The results of Meta analysis suggested that pa-tients and healthy volunteers of elbow MRI showed statistically significance [OR=88.55, 95%CI=(29.20, 268.57)]. Between ipsilateral elbow and contra lateral of elbow MRI showed statistically significance [OR=80.17, 95%CI=(21.53, 298.59)]. MRI analysis showed that in addition to signs of extensor tendon injury, the elbow was also widely associated with other changes, such as radial collateral ligament in-jury, bone marrow edema, joint effusion, tendon tear, and elbows muscle edema. Conclusion Through MRI findings,the maln pathological changes of the so-called lateralepicondyliti-saremalnly for total ex-tensor tendon and adjacent tissue of chronic injury, Naming the current external humeral epicondylitis is unreasonable. Therefore, periarthritis of lateral epicondyle of humerus seems to be the best appropri-ate term to be usedwhenthe ninth edition surgery textbooksisauthorized.
