Objective To explore the association of apoB gene polymorphisms with dyslipidemia and lipid levels in Xinjiang Shihezi Han Chinese. Methods 150 dyslipidemia patients and 150 normal pople were involved in this study. EcoRI and XbaI polymorphisms of apolipoprotein B was analyzed by PCR-restriction fragment length polymorphism. The levels of plasma total cholesterol, triglyceride, low density lipoprotein cholesterol, high density lipoprotein cholesterol, apoAI and apoB were determined. Results The frequency of E + E -/E - E - genotype and E-Allele(37.3% and 19% ) in dyslipidemia group was significantly higher than that in controls( 12. 7% and 6. 3% ). The levels of TC, TG and LDL-C in the E +E -/E - E - gene type were significantly higher than those of the E + E + gene type in each group ( P <0. 01 ). The frequency of X + X -/X + X + genotype and X + Allele( 20. 7% and 1 1% ) in dyslipidemia group was significantly higher than that in controls (8% and 4% ). The levels ofTC, TG, LDL-C and apoB in the X + X -/X + X + gene type patients were significantly higher than those in the X - X - gene type patients in every group ( P < 0. 05 ). Conclusion The EcoRI and XbaI polymorphism of ApoB gene was related to dyslipidemia in population of Xinjiang Shihezi Han Chinese, and the E - and X + Allele may be the genetic risk factors for dyslipidemia.

Objective To investigate the feasibility of a novel molecular probe 99Tcm-3P4-RGD2 in evaluating arterial plaque stability after atorvastatin intervention in rabbits with SPECT/CT. Methods Eighteen male New Zealand rabbits were randomly divided into group A (stable plaque), group B (vulnerable plaque), and group C (vulnerable plaque with statin intervention). All rabbits were fed with high-fat food for 12 weeks. After high-fat feeding for two weeks, sham surgery was performed on group A. In the meantime, abdominal aorta injury was performed on group B and group C. After that, rabbits of group C were given oral atorvastatin (2.5 mg·kg-1·d-1). 99Tcm-3P4-RGD2 SPECT/CT imaging was performed on each group at the end of 4, 8 and 12 weeks. T/NT ratios were calculated. Animals were sacrificed at the end of 12 week after imaging studies. The abdominal aortas were collected, imaged with SPECT/CT, and evaluated by pathological HE staining and immunohistochemical analysis. MVD was calculated. Differences among 3 groups were analyzed using one-way analysis of variance. Results There was no significant radioactive uptake in the abdominal aortas of three groups on the 4th week′s imaging. The radioactive uptake in abdominal aortas increased slightly on the 8th week, with the highest radioactive uptake in group B. The radioactivity in abdominal aortas of the 3 groups maintained increasing on the 12th week, with T/NT ratios of 1.579±0.217, 1.873±0.226 and 1.524±0.237, respectively (F=8.984, P<0.05). In ex vivo abdominal aorta images, especially images of group B, radioactivity in lesion sites was higher than that in normal tissue. Accordingly, results of HE staining showed that artery plaques of group A and group C were grade Ⅱ and group B was grade Ⅳ. The MVD of group A, B and C was 8.17±1.17, 15.86±1.07 and 7.17±1.60, respectively (F=9036, P<0.05). Conclusion 99Tcm-3P4-RGD2 SPECT/CT imaging has a high sensitivity in the evaluation of arterial plaque stability after statin intervention in rabbits.

Objective Metabolites produced by metabolic imbalance such as free fatty acids and lipopolysaccharides can result in a state of chronic low-grade inflammation, or metabolic inflammation, which plays an important role in the pathogenesis of atherosclerosis, type 2 diabetes, non-alcoholic fatty liver disease, and obesity. The above metabolic disorders are closely related with the metabolic inflammation, which always coexist. Therefore, we proposed the concept ofmetabolic inflammatory syndrome ( MIS). According to our study, patients with two or more metabolic disorders above could be diagnosed as MIS. The current research is aimed to investigate the prevalence of MIS and its components, and to compare the clinical values of MIS and metabolic syndrome ( MS) . Methods 2 001 in patients with type 2 diabetes from 6 hospitals in Shanghai were recruited in the current multi-center cross-sectional study. The diagnostic rates of MIS and MS and their components of both syndromes were compared. Results In the patients with type 2 diabetes, the detective rate of MIS was 96. 2%, which was higher than that of MS (71. 3%). Among 4 components of MIS, atherosclerosis showed the highest detective rate (75.6%). MIS[OR=2.252(95%CI1.026-4.942),P=0.043],atherosclerosis[OR=2.726(95% CI1.953-3. 804),P<0. 001], and MS[OR=1. 915 (95%CI 1. 444-2. 540),P<0. 01] were the risk factors of coronary heart disease. Conclusion With atherosclerosis, type 2 diabetes mellitus, non-alcoholic fatty liver disease, and obesity as its 4 components, MIS has a high detective rate in patients with metabolic disorders, and seems to be more sensitive than MS to distinguish inflammation-related metabolic diseases. The concept of MIS will promote the screening and prevention of atherosclerosis in its early stage.

Objective To investigate the value of pulmonary ventilation/ perfusion (V/ Q) SPECT in evaluation of anticoagulant therapy for patients with pulmonary embolism (PE) and identify factors which may affect the therapy. Methods From July 2014 to December 2016, sixty-three patients (23 males, 40 females, age (60±14) years), who were clinically diagnosed as PE and underwent V/ Q SPECT before and after anticoagulant therapy, were recruited retrospectively in this study. According to the percentage of lung perfusion defect (PD) out of total lung volume, the patients were divided into mild (<20%) PE, moderate (20%-50%) PE, and severe (>50%) PE groups. The lung PD decreased≥50% after anticoagulant thera-py and no new PD detected was defined as the standard of effective therapy, otherwise the treatment were defined as ineffective. Data of different groups were compared. Factors that may predict the severity of PD or affect the treatment were analyzed. χ2 test and logistic regression were used for data analysis. Results PE were detected in 476 pulmonary segments and sub segments. The distribution of PE in different lung lobes had no statistically significant difference ( χ2 = 4. 995, P > 0. 05). More pulmonary arterial hypertension (PAH) were detected in patients with severe PE (80%, 12/ 15) and moderate PE (66.7%,16/ 24) in comparison with patients with mild PE (41.7%,10/ 24; χ2 = 7.062, P<0.05). The occurrence of PAH was related to the severity of PD, with odds ratio (OR) value of 2.680 (95% CI: 1.115-6.446, P<0. 05).PAH was an independent risk factor for treatment effect (OR value: 3.134(95% CI: 1.341-7. 324), P<0. 05). Conclusions V/ Q SPECT has an important value for evaluating the effect of anticoagulant therapy and guiding individual therapy. The more extent of PE involved, the higher prevalence of PAH. Anticoagu-lant therapy may be ineffective in PE patients with moderate or severe PAH.

Acute pain is a common complication after injury of a peripheral nerve but the underlying mechanism is obscure. We established a model of acute neuropathic pain via pulling a pre-implanted suture loop to transect a peripheral nerve in awake rats. The tibial (both muscular and cutaneous), gastrocnemius-soleus (muscular only), and sural nerves (cutaneous only) were each transected. Transection of the tibial and gastrocnemius-soleus nerves, but not the sural nerve immediately evoked spontaneous pain and mechanical allodynia in the skin territories innervated by the adjacent intact nerves. Evans blue extravasation and cutaneous temperature of the intact skin territory were also significantly increased. In vivo electrophysiological recordings revealed that injury of a muscular nerve induced mechanical hypersensitivity and spontaneous activity in the nociceptive C-neurons in adjacent intact nerves. Our results indicate that injury of a muscular nerve, but not a cutaneous nerve, drives acute neuropathic pain.
