AimTo investigate the immune effects of the genetic engineering vaccine against swine cysticercosis with the animal mode of kunming mouse. Method78 kunming mice were randomly divided into three groups: 1 )injection one times with the vaccine, 2)injection twice with the vaccine at intervals of ten days, 3)non-vaccination group. All the mice were infected with the vial hatched oncopheres by the tag vein at 20 days after the first vaccination,and were killed and dissected to look for swine cysticerci 63 days later. In order to know the immune response of the vaccine and the stateof parasites in the rats,the antigens and antibodies of swine cysticerci were detected by immune methods. ResultsThe vaccine was safety to all the vaccinated rats. The antibodies against swine cysticerci began to appear positive in some of the immunized mice at 7 days postvaccination,and they were all positive at 21 days. 65 cysticerci were found in the mice of the nonvaccination group,which lodged mainly in the chests. 2 and lcysticerci were respectively found in two rats of the first group and in one rat of the second group, their protective rates of cysticerci were 96.9％ and 98. 4％,respectively. ConclusionKunming mouse as the animal model of swine cysticercosis was stable and reliable,and the genetic engineering vaccine against swine cysticercosis was safety and efficiency.

Objective To establish an efficient HPLC method for the determination of uric acid in plasma of hyperuricemia model mice,and the evaluation of uric acid lowering effect of Lesinurad.Methods The Laballiance Series Ⅲ HPLC system was adopted with Kromasil C18 column (100 mm × 4.6 mm,5 μm).The mobile phase consisted of methanol-0.5％ acetic acid (10:90) for isocratic elution with a flow rate of 0.4 mL/min.The detection wavelength was set at 283 nm.The established HPLC method was used to detect the plasma uric acid level of mice at 0.5,1.0,and 2.0 h time points after which being ip injected with 250 and 500 mg/kg uric acid.Lesinurad of 250 and 500 mg/kg was ig given to mice,0.5 h later,mice were ip injected with 500 mg/kg uric acid to establish hyperuricemia model,and 1 h later,the established HPLC method was used to detect the plasma uric acid level of mice.Results There was a good linear relationship between peak area and the concentration of plasma uric acid in the range of 7.5-150 μg/mL (r =0.997).The specificity,repeatability,precision,stability,and recovery of the established HPLC method was in accordance with the guiding rules of biological sample determination.Compared with the endogenous serum uric acid concentration of control group mice,serum uric acid concentration of 250 mg/kg dose group was significantly increased 0.5 h after ip administration with uric acid (P ＜ 0.01),and serum uric acid concentration of 500 mg/kg dose group was significantly increased 0.5,1.0,and 2.0 h after ip administration with uric acid.Compared with model group,the concentration of uric acid in plasma decreased significantly in low dosage group administered with Lesinurad (P ＜ 0.05),while decreased more significantly in high dosage group (P ＜ 0.01).Conclusion This convenient,rapid,and accurate method can be applied to the determination of uric acid in mouse plasma and the evaluation of relative drugs,which provide an efficient analysis way for establishing hyperuricemia model and screening relative drugs.

Objective To evaluate the relationship between echocardiographic epicardial adipose tissue thickness(EAT) and the presence and severity of coronary artery disease(CAD). Methods One hundredand forty-seven patients (101 patients with CAD and 46 patients with normal coronary arteries by diagnostic coronary angiography) were enrolled. EAT thickness was measured using 2-D echocardiographic parasternal long-and short-axis views. EAT thickness measurements were compared with angiographic findings. Results EAT was significantly higher in CAD group comparison to control group [(7.41 ± 1.63)mm vs (4.41±1.60) mm, P ＜0.01 ]. Furthermore, EAT increased with the severity of CAD [(8.53 ± 1.00)mm vs (6.36 ±1.73)mm, P ＜0.01]. Gensini's score significantly correlated with EAT (r = 0.71, P ＜0.01 ). EAT thickness ≥5.35 mm had 87.13% sensitivity and 80.42% specificity (ROC area 0. 89, P = 0.01,95% CI [0.84 - 0.9;]) for predicting CAD. Conclusions EAT thickness, which is easily and non-invasively evaluated by transthoracic echocardiography, can be an adjunctive marker to classical risk factors for the prediction of CAD, it was significantly correlated with the severity of coronary artery disease.

Objective To investigate the effect of surgical treatment of adult mandibular condylar fractures (including intracapsular fracture). Methods Thirty-two patients (33 sides) with condylar fractures underwent open reduction and rigid fixation. Six patients with intracapsular condylar fractures were treated with two 18-mm positional screws through a preauricular approach. Six patients (7 sides) with condylar neck fractures were rigidly fixed by 1 mini-plate via a retromandibular transparotid approach. Twenty patients with subcondylar fractures were operated and fixed by two titanium plates using an angular approach. Results The mean follow-up period was 13.5 months, and the mean maximum mouth opening was 37.5 mm by the last visit. All patients acquired good occlusal relationship and mandibular symmetry. Seven patients (21.9%) experienced transient palsy of the branches of the facial nerve, and recovered completely after three months. One patient developed a salivary fistula, and healed after two weeks of gauze compression. No permanent deficit of any facial nerve branch was observed. No patient showed condylar head resorption. Conclusion Appropriate surgical approaches and fixation methods for different types of condylar fractures are the key factors to achieve reliable clinical results.

Objective: To evaluate the association of smoking with the risk of ankylosing spondylitis (AS) using a Mendelian randomization (MR) approach. Methods: A total of 16 383 186 AS-associated single nucleotide polymorphisms (SNPs), 378 smoking initiation associated SNPs and 126 lifetime smoking score-associated SNPs were collected from three large-scale genome-wide association studies (GWAS). The association of smoking phenotypes with the risk of AS was examined using inverse-variance weighted (IVW) with AS as a outcome variable, smoking initiation and lifetime smoking score as exposure factors and SNPs with strong associations with smoking as instrumental variables, and sensitivity analyses were performed with maximum likelihood-based method, MR pleiotropy residual sum and outlier (MR-PRESSO) test and MR-Egger regression analysis. Results: A 33.5% increased risk of AS was found among genetically predicted smokers relative to non-smokers (OR=1.335, 95%CI: 1.059-1.682), and an increase in predicted lifetime smoking by per standard deviation resulted in a 101.4% increased risk of AS (OR=2.014, 95%CI: 1.341-3.024). The maximum likelihood-based method and MR-PRESSO test showed consistent correlated effect estimations and MR-Egger regression analysis identified no evidence of pleiotropy. Conclusion It is genetically predicted that smoking is associated with an increased risk of AS.

Objective To investigate the value of shear wave elastography (SWE) indirect evaluation on parotid function in Sjogren syndrome (SS) patients.Methods According to parotid function evaluated with scintigraphy,100 SS patients were divided into normal group,mild group,moderate group or severe group.SWE was performed in all the patients,and Young's modulus of parotid gland was obtained.The difference of Young's modulus among the four groups were compared,and the correlation between Young's modulus and paratid gland function were analyzed.ROC curve was used to evaluate the efficacy of Young's modulus in diagnosis of severe parotid function damage.Results The difference of Young's modulus among four groups was statistically significant (F=78.60,P＜0.001).Young's modulus increased with the damage severity of parotid function (rs =0.83,P＜0.001).Taking 38.38 kPa as threshold,the area under ROC curve of Young's modulus was 0.93 (P＜0.001) in diagnosis of severe parotid function damage and the sensitivity and specificity was 89.3％ and 84.7％,respectively.Conclusion SWE can indirect evaluate parotid function in SS patients,and is valuable in diagnosis and long-term follow-up of SS.

The sigma-1 receptor is a molecular chaperone protein highly enriched in the brain. Recent studies linked it to many diseases, such as drug addition, Alzheimer's disease, stroke, depression, and even cancer. Sigma-1 receptor is enriched in lipid rafts, which are membrane microdomains essential in signaling processes. One of those signaling processes is ADAM17- and ADAM10-dependent ectodomain shedding. By using an alkaline phosphatase tagged substrate reporter system, we have shown that ADAM10-dependent BTC shedding was very sensitive to both membrane lipid component change and sigma-1 receptor agonist DHEAS treatment while ADAM17-dependent HB-EGF shedding was not; and overexpression of sigma-1 receptor diminished ADAM17- and ADAM10-dependent shedding. Our results indicate that sigma-1 receptor plays an important role in modifying the function of transmembrane proteases.
