Objective To study the variation of serum IL-18 and TNF-? in infants with cytomegalovirus (CMV) hepatitis before and after treatment. Methods The levels of serum IL-18 and TNF-? in 36 infants with CMV-hepatitis before and after treatment and in 21 normal infants were detected by enzyme linked immunosorbent assay (ELISA). Results Serum levels of IL-18 and TNF-? in infants with CMV-heptitis were obviously higher than those in normal infants (P

Objective To compare the therapeutic effect of endovascular repair (EVAR) and open surgical repair(OSR) of abdominal aortic aneurysm in high-risk patients. Methods The clinical data of 55 patients from 1998 to 2008 with infrarenal abdominal aortic aneurysm who received surgical treatment were analyzed by using the customized probability index. The perioperative and short term advantages and disadvantages of OSR group (n=20) were compared with EVAR group (n=35). Results All patients in OSR group were followed up, 94% patients in EVAR group were followed up, the mean follow up time were 75 and 70 months respectively. (1) Compared to OSR group, the EVAR group had shorter operation time [(3.1±0.6) h vs (4.9±0.9) h, P<0.05], (2) EVAR group had shorter ICU and hospital stay after operation and less blood loss (P<0.01), (3) Compared to OSR group, the EVAR group had lower mortality within 30 d(2.86% vs 15%), (4)the EVAR group had lower peri-operative complications(17% vs 40%), (5) The main complications of EVAR were endoleak (8.57%), (6) The main complications of OSR was cadiovascular incidence(25%). Conclusions Endovascular treatment, indicated for AAA in high-risk patients, can cut down the perioperative incidence of cadiovascular events, mortality and complications. CPI is useful to estimate the perioperative incidence of cadiovascular events, mortality and complications, and can be used to guide the therapeutic method.

Objective The aim of our study is to establish and characterize the animal model for au- toimmune myositis.Methods Fifty male SD rats were randomly divided into 2 groups:model group(n=40) and control group(n=10).The model group rats were immunized with muscle homogenate every week for 5 weeks and received an injection of 2?g pertussis toxin at the first and second week.As controls,10 SD rats were injected with an equal volume of normal saline.Tissue specimens from limb skeletal muscles were ob- tained at 1,2,3,4,5 weeks after injection.At the same time,the blood samples were collected,and the level of CPK was measured.Results The model group had significantly elevated serum CPK levels.There were multiple inflammatory lesions in the skeletal muscles.Local degeneration and necrosis of muscle fibers with disappeared transverse striation,mononuelear cell infiltration in the interstitial could be observed.The patho- logic grade was mainly 2a.The infiltrating mononuclear cells were predominantly CD8~+T cells that mainly lo- cated in the endnmysium.MHC classⅠantigen expression on muscle fiber membranes in the model group was upregulated.Conclusion The experimental autoimmune myositis induced by syngeneic skeletal muscle ho- mogenate in SD rat is pathologically similar to human myositis.It can be used as a good model for human myositis and provides the basis for the etiopathology and therapeutical studies.

Objective To evaluate the safety and efficacy of endovascular repair(EVR)for type B acute aortic dissection(AAD). Methods Between Feb 2002 and May 2008.39 consecutively admitted patients with the confirmed diagnosis of acute type B aortic dissection were studied.All patients were treated bv EVR.Left comnlon carotid artery were covered after bypass in 2 cases.of which fenestrated stent graft (SG)at innominate artery was used in one;1 case underwent left lower extrernity amputation:13 left subclavian artery(LSA)and 1 aberrant risht subclavian artery were completely covered without bypass.5 LSA were pattially covered.All cases were followed by CTA after EVR.the porfusion status of the false lumen were monitored in the aorta at the level of the stented segment(L1)and distal to the stent graft (L2).Results The procedure Was technically successful in all cases;30-day mortality rate was 10.3%.At the 1-month follow-up,false lumen in L1 thrombosed in 100%,a complete thrombosis of the false lumen Was observed in 21 patients(77.8%).partial thrombosis in 6(22.2%).with complete reabsorption of the thrombus and remodelling of the true lumen in 5(18.5%);False lumen in L2 thrombosed only in 7 patients(28%),complete thrombosis in 2(8%)and partial thrombosis in 5(20%).Conclusions The results of endovascular repair of acute type B dissection Was satisfactory.30-day mortalitv rate was related to severe complications before EVR.

OBJECTIVETo evaluate the antiviral efficacy of Bushen Granule (BSG) combined with Marine Injection (MI) in treating patients with chronic hepatitis B of Gan-shen deficiency with Damp-Heat (GSD) syndrome type.

METHODSA total of 90 patients, who were HBV DNA, HBsAg, and HBeAg positive and of GS-DD type, were enrolled, and they were randomly assigned into 2 groups. The 49 patients in the treated group were treated with the combined therapy of BSG and MI and the 41 were administered with lamivudine, the therapeutic course for both groups was 1 year. The negative conversion rate of HBeAg and HBV DNA and the changes in HBV DNA titre, liver function, symptoms and physical signs were observed in the two groups before and after treatment.

RESULTSIn the treated group, the negative conversion rate of HBV DNA was 42.6% (20/ 47), insignificantly different to that in the control group (61.0%, 25/41, P > 0.05); the negative conversion rate of HBeAg and HBeAg/anti-HBe sero-conversion rate was 42.6% and 36.2%, respectively, significantly higher than those in the control group (22.0% and 17.0%, P < 0.05); the ALT normalizing rate was 74.4%, higher than that in the control group (51.4%, P < 0.05); the improvement of liver function (ALB and GLB) and clinical symptoms, especially the dizziness, soreness of waist, hypochondrial distending pain, and yellowish urine, were significantly superior to those in the control group(P < 0.01 or P < 0.05); and the partial response rate was 29.8%, insignificant different to that in the control group (14.6%, P > 0.05).

CONCLUSIONSCombined treatment of BSG and MI has an ideal short-term effect in treating patients with chronic hepatitis B of Gan-shen deficiency with Damp-Heat syndrome type, it can inhibit HBV replication and improve patients' liver function and physical signs.

In order to clarify Avian leukosis virus (ALV) characteristics from Chinese native chicken breeds, three ALV JS11C1, JS11C2 and JS11C3 were isolated from Chinese native breed "luhua" by inoculation of DF1 cell culture and detection of p27 antigen. Using PCR amplification of env gene, the amplified gp85 genes were analyzed and compared to all six chicken ALV subgroups reported. The gp85 genes of these three viruses were 1 005bp in length and encoded 335 amino acids, and the gp37 genes were 609bp and encoded 203 amino acids. The homology of gp85 among these three isolated strains was 91.9%-97.0%. Comparing to 18 stains of subgroup A, B, C, D, E published in GenBank, the homology was only in the range of 77.7%-84.6%, significantly lower than the gp85 homology observed within the common chicken subgroups A (88.2%-98.5%), B (91.6%-98.8%), and E (97.9%-99.4%). The gp85 homology compared with subgroup J was only 34.2%-36.5%. These results suggested that three isolated strains from Chinese native breed "luhua" belong to a new subgroup different from all six known subgroups from Chickens, and thus designated as subgroup K.

Chinese traditional patent medicine for promoting blood circulation and removing blood stasis(PBCRBS) originated from traditional Chinese medicine theory and had approved efficacy and safety standards. However, its compatibility regularity and anti-thrombotic mechanism is not clear. To analyze the compatibility regularity and anti-thrombotic mechanism of Chinese traditional patent medicine for PBCRBS, a statistical and bioinformatics analysis was carried out using traditional Chinese medicine inheritance support system (TICMISS, V2.0) and ingenuity pathway analysis (IPA). The compatibility regularity analysis shows that the most commonly used herb combinations are Danshen (Salvia miltiorrhiza Bge.), Chuanxiong (Ligusticum chuanxiong Hort.) and Honghua (Carthamustinctorius L.). The anti-thrombotic mechanism analysis reveals that 25 ingredients have an effect on 29 thrombosis related molecules which 23 molecules are related to inflammation response. Furthermore, there are 5 inflammation molecules (NOS2, PTGS2, IL6, TNF, IL1β) served as major targets. At the same time, Danshen, Chuangxiong and Honghua mainly used as sovereign herb or minister herb in the application of cardiovascular and cerebrovascular diseases. Therefore, Chinese traditional patent medicine for PBCRBS probably has an effect on anti-thrombotic activity through inhibiting the inflammatory response. In summary, the most commonly used herb combinations of Chinese traditional patent medicine for PBCRBS are Danshen, Chuanxiong and Honghua. Inhibiting inflammatory response, especially inflammation related molecules (NOS2, PTGS2, IL6, TNF and IL1β), is probably a new starting point to clarify the anti-thrombotic mechanism of Chinese patent medicine for PBCRBS.

OBJECTIVE To investigate the clinical pathological characteristics of differentiated thyroid carcinoma (DTC) in children and adolescents. METHODS The clinical data of 30 children and adolescents with DTC were retrospectively reviewed. Meanwhile the clinical pathological characteristics of DTC were analyzed according to patients' age and gender. RESULTS Papillary thyroid carcinoma (PTC) was found in 27 cases and follicular thyroid carcinoma (FTC) in 3 cases. The average diameter of tumors was (2.56±1.1) cm. In the group of children, the incidence of lymph node metastasis was 92.3% (12/13), pulmonary metastasis was 46.2% (6/13), and those in the group of adolescents was 88.2% (15/17) and 35.3% (6/17) respectively. Children group tended to present with more vascular invasion, thyroid capsule invasion, and invasion out of thyroid, and a higher rate of cervical lymph node metastasis (P=0.025, 0.007, 0.025, 0.033). CONCLUSION Thyroid carcinoma in childhood and adolescent has a stronger invasive feature. It is easy to local invasion, lymph node and distance metastasis.

Objective To study the COLIXA3 gene polymorphism of patients with fluorosis and to explore the pathogenesis of COLIXA3 gene in endemic fluorosis.Methods Fifty one cases of patients with drinking-water borne fluorosis were selected as the case group in Xinzhou city,Shanxi province and 28 cases of healthy people were as the control group.Dental fluorosis was detected by Dean method and skeletal fluorosis was examined by X-ray.COLIXA3 of exon 5 gene product of 103 points was amplified by PCR and the gene locus genotype was sequenced.Results Ten cases of mild dental fluorosis,14 cases of moderate dental fluorosis,15 cases of severe dental fluorosis were detected among the 51 patients.The control group was free of dental fluorosis.All the 51 cases of patients with fluorosis had varying degrees of skeletal fluorosis,mainly osteosclerosis lesions,accounting for 86.27％(44/51 ),and mild skeletal fluorosis patients were all osteosclerosis lesions,and osteosclerosis lesions and multiple skeletal lesions were found among moderate and severe skeletal fluorosis patients in the case group,while control group had no skeletal fluorosis.The differences between genotypes of frequency distribution of AA,Aa,aa of COLIXA3 of case and control groups were not statistically significant [96.08％(49/51 ),3.92％(2/51 ),0.00％(0/51) and 96.43％(27/28),3.57％(1/28),0.00％(0/28),x2 =0.94,P ＞ 0.05].ConclusionsCOLIXA3 gene polymorphism is not significantly correlated to fluorosis.
