Objective To investigate the role of DWI in differentiating autoimmune pancreatitis ( AIP) from pancreatic cancer ( PC) , and in the therapeutic effect evaluation of AIP.Methods DWI data of 26 cases with AIP , 29 cases with PC and 30 cases with normal pancreas ( NP ) were analyzed retrospectively.The distribution type and signal feature of lesions in cases with AIP or PC were evaluated by Chi-squared test.ADC values were measured and compared among 3 groups by Kruskal-Wallis test.ADC values of AIP and PC were analyzed by using ROC curve to determine the optimal threshold and diagnostic efficiency.ADC values were compared in AIP ( n=15 ) before and after steroid therapy by paired t test.Results Diffuse lesions were detected in 21 cases with AIP and 3 cases with PC, while focal lesions in 5 cases with AIP and 26 cases with PC (χ2 =27.64, P<0.01).On DWI, most of AIP (n=19) and PC (n=24) showed hyper-intense signal, while a few of AIP (n=7) and PC (n =5) showed iso-intense signal (χ2 =0.75, P>0.05).The median ADC values of AIP, PC and NP were 1.15 ×10 -3,1.35 × 10 -3 ,1.59 ×10-3 mm2/s, respectively; and the difference was statistically significant ( H=45.60, P <0.01).ROC analysis yielded an optimal ADC cutoff value of 1.255 ×10 -3 mm2/s (80.8% sensitivity, 79.3%specificity and 0.871 area under curve for the diagnosis of AIP ).ADC values of AIP ( n=15) were markedly increased from the baseline (1.10 ±0.19) ×10 -3 to (1.57 ±0.12) ×10 -3 mm2/s after steroid therapy (t=-10.14, P<0.01).Conclusions DWI may be useful for diagnosing and evaluating the effect of steroid therapy in AIP.ADC values of AIP were significantly lower than those of pancreatic cancer and normal pancreas.After steroid therapy , ADC values were markedly increased in AIP.

OBJECTIVETo construct a lectin-like oxidized low-density lipoprotein receptor (LOX-1) RNA interference (RNAi) lentivirus and explore the role of LOX-1 in H(2)O(2)-induced apoptosis of rat myocardial cells.

METHODSLOX-1 shRNA sequence was synthesized and cloned into pLentiLox3.7 (pLL3.7) lentiviral vector to construct the lentiviral vector pLL3.7-LOX1. The lentiviral vectors (pLL3.7 and pLL3.7-LOX1) and the packaging vectors dR8.9 and VSVG were co-transfected into 293FT cells for packaging the lentivirus. H9C2 myocardial cells were infected by the lentiviruses to observe the inhibitory rate of LOX-1 on H(2)O(2)-induced apoptosis of H9C2 cells by RT-PCR, CCK-8, and Hochest33258 staining.

RESULTSDouble restriction enzyme digestion and DNA sequencing confirmed correct insertion of the sequence. Suppression of LOX-1 by the lentivirus attenuated H(2)O(2)-induced cell viability reduction and apoptosis in the myocardial cells (P<0.01).

CONCLUSIONLOX-1 activation may play an important role in H(2)O(2)-induced apoptosis of rat myocardial cells.

Objective: To evaluate the efficacy and safety of portal vein stenting combined with 125I particle strand implantation followed by drug-eluting beads transarterial chemoembolization (DEB-TACE) and molecular-targeted therapy for the treatment of stageⅢa liv-er cancer lacking a blood supply. Methods: A retrospective analysis of 11 patients who had stageⅢa liver cancer lacking a blood sup-ply combined with portal vein tumor thrombosis (PVTT) was conducted from October 2016 to October 2018. All the patients under-went portal vein stenting combined with 125I particle strand implantation, DEB-TACE, and comprehensive treatment containing molecu-lar-targeted drugs. During the follow-up period, all patients were evaluated for stent patency after the implantation and tumor re-sponse after DEB-TACE treatment. The liver function and blood routine changes before and 1 month after the surgery were completed, and the complications were summarized. Results: All 11 patients were judged as stageⅢa liver cancer based on the Chinese staging criteria (2017), Child-Pugh classification grade A and B. The imaging findings indicated that these tumors were hypovascular. The maxi-mum diameter of these lesions was (8.4±4.1) (2.8-14.1) cm, and all patients had PVTT. Among them, there were 4 cases of Cheng's typeⅡand 7 cases of typeⅢ: 6 cases of main PVTT≥50% and 1 case of PVTT<50%. All patients underwent portal vein stenting com-bined with 125I particle strand implantation, DEB-TACE, and comprehensive treatment containing molecular-targeted drugs. Three and 6 months after stent implantation, the patency rate was 100%; 3 months after DEB-TACE treatment, complete response was achieved in 4 (36.4%) patients, partial response was achieved in 5 (45.5%) patients, and stable disease was achieved in 2 (18.2%) patients. No patients exhibited progressive disease. Therefore, the objective response rate was 81.8% and disease control rate was 100%. As for the liver and kidney function and blood routine tests, there were no significant differences between baseline and 1 month after the sur- gery. In addition, no patient had any serious complication during the perioperative period. Conclusions: For patients with stageⅢa liv-er cancer lacking a blood supply and PVTT, a comprehensive treatment strategy including portal vein stenting combined with 125I parti-cle strand implantation, DEB-TACE, and molecular-targeted therapy can restore portal vein blood flow and maintain mid-and long-term stent patency, while effectively killing tumors and controlling tumor growth, which is a safe and effective treatment strategy.

Objective: To determine the effects of ginsenoside rg3 on the body weight of C57BL/6J obese mice and to investigate its underlying weight loss mechanisms with a focus on white fat browning-related factors. Methods: Eight-week-old C57BL/6J male mice were fed a high-fat diet for 12 successive weeks to construct the obese model. C57BL/6J male mice were fed a standard chow diet to construct normal control group. After 8 weeks of intervention with ginsenoside rg3, the food intake, body weight, body fat mass, blood sugar, and lipid profiles of the mice in each group were detected. Hematoxylin and eosin (HE) staining was used to observe the histological morphology of the adipose tissues. Real-time poly-merase chain reaction (RT-PCR) and Western blotting (WB) were applied to detect the gene and protein expression levels of peroxisome proliferators-activated receptor gama (PPARγ), Peroxisome proliferator-activated receptor-gamma coactivator -1alpha (PGC-1α), PR domain containing 16 (PRDM16), and uncoupling protein 1 (UCP-1).Results: Compared to normal control group mice, the body weight, food intake, body fat composition, and blood lipid levels of model group mice increased significantly. After 8 weeks of intervention with ginsenoside rg3, body weight, body fat composition, food intake, and blood lipid profiles decreased. HE staining showed that ginsenoside rg3 can improve white adipocyte hypertrophy to a certain extent. RT-PCR and WB demonstrated that ginsenoside rg3 can increase the mRNA and protein expression levels of PPARγ, PGC-1α, PRDM16, and UCP-1 in the adipose tissues of obese mice. Conclusion: The weight reduction effect of ginsenoside rg3 may be related to the promotion of white fat browning.

Vesicular glutamate transporter 2(VGlut2)is expressed in the PVN of the hypothalamic paraventricular nucleus(PVNVG1ut2)as an excitatory neurotransmitter,which regulates food intake and energy metabolism and plays an important role in maintaining homeostasis.However,it is not clear that the upstream and downstream projection network of PVNVGut2 neurons hinders the anal-ysis of glutamatergic neuron circuit function.Anterograde and retrograde tracer viruses were injec-ted into the PVN of VGlut2 mice by stereotactic brain injection technique to find the input and output nuclei of PVNVGlut2 neurons.Anterograde tracing results showed that PVNVGlut2 neurons pro-jected to the downstream medial amygdala(MeAD)and arcuate nucleus(ARC).Retrograde trac-ing results showed that PVNVGlut2 received input from the prefrontal nucleus(Pr),the reticular tegmental nucleus(RtTg),and the hypoglossal nucleus(12N).In addition,VGlut2 was found to be co-expressed with neuronal nitric oxide synthase(nNOS)neurons in the PVN.The anatomical net-work of PVNVG1ut2 neurons was analyzed by virus tracking tool,which laid the anatomical founda-tion for further study on the functional regulation of PVNVGlut2.
