China Medical Equipment 2017;14(5):49-51
Objective:To explore the application value of multislice spiral CT scanning on abdomen for the detection of complication of acute pancreatitis.Methods: 120 patients with acute pancreatitis were divided into observation group (70 cases) and control group (50 cases) according to different detection method. The patients of control group were applied basic clinical detections included X-ray radiography and ultrasound imaging, while patients of observation group were supplemented CT detection besides these detections of control group. And situation of complication of patients in two groups were observed.Results: The positive rate of complications, which involved pancreatic pseudocyst, cellulitis, complications of gastrointestinal tract, pancreas hemorrhage and pancreatic ascites, in observation group was 97.14%, that was significant higher than that (62.0%) of control group (x2=24.74,P<0.05). Among 20 patients with pancreatic pseudocysts, there were 9 patients located at tails of pancreases, 6 patients located in bodies of pancreases, 3 patients located in small omental bursas, 2 patients located at heads of pancreases, and the CT images of them showed quasi-circular liquid form density lesions with clear boundaries appeared in lesion field. The CT images of cellulitis showed the volume of pancreas increased and the boundaries were fuzzy, and a larger range of density lesions with irregular soft tissue shape appeared in its periphery. CT detetions of gastrointestinal complications showed fuzzy point-shaped, strip-shaped and flake-shaped soft tissue-styled density shadow appeared in gastrointestinal tracts. The CT image of pancreatic ascites showed intraperitoneal fluid density shadow.Conclusion: Abdominal CT scan applied on patients with acute pancreatitis can increase the positive rate of complications and may be used as preferred detection method for clinical evaluation on the complications of acute pancreatitis.

Objective To explore the risk factors of coronary artery plaque progression and the clinical indexes that could predict plaque progression. Methods The 142 patients had twice coronary artery angiographs were enrolled in this study. Quantitative coronary angiography (QCA)was performed to evaluate angiographs at baseline and follow-up. Results According to the changes of minimum lumen diameter (MLD) in twice angiographs being or not more than 0.4 mm, the patients were divided into plaque progression group (n=54) and non-plaque progression group (n=88). The incidences of myocardial infarction (MI) and diabetes were significantly higher in plaque progression group than in non-plaque progression group [27.8% vs. 5.7%, 63.0% vs. 36.4%], and the serum levels of high-sensitivity C-reactive protein (hs-CRP, 14.5 mg/L vs. 6.3 mg/L) and neutrophil (6.6×109/L vs. 4.3×109/L) were also significantly higher. The incidence of coronary artery plaque progression in patients with high hs-CRP level was 2.52 times higher than in patients with low hs-CRP level, and the incidence in patients with myocardial infarction was 3.98 times as much as patients without MI. Conclusions The hs-CRP and myocardial infarction were the independent risk factors for coronary artery plaque progression.

Objective To explore a biodegradable drug?loaded composite scaffold and determine its bone regeneration and local long?term drug release ability. Methods In this study, RFP?loaded a novel poly (caprolactone)?b?poly (lactide?co?gly?colide)/β?TCP composite scaffold was produced using particle?leaching/freeze?drying technique. And the obtained composite scaffold was characterized by SEM, TGA, UV spectrophotometer, universal testing machine and so on. New Zealand rabbits were used to prepare bone defects, which was treated by the implantation of active artificial bone loaded with or without RFP. The blank group was untreated. Then the repairing effects of the materials were examined. Results The obtained porous scaf?fold has inter?connected and uniformly distributed pores, and the diameters of pores range from 200 μm to 300 μm. Many mi?cropores (10 μm to 50 μm) can be observed on the wall of macropores. The total porosity of the porous composite scaffold can reach as high as 83.4%; the β?TCP content of the scaffolds is 51.2%. Meanwhile, the addition of β?TCP avoided volume shrinkage compared with b?PLGC scaffold; Additionally, the porous composite scaffold has good compressive strength ( 240 kPa) and compressive modulus (1.0 MPa); And the drug loading of the scaffold was 3.2%,which could smoothly release drug for 63 days after a period of burst release for a week. All defects in the experimental groups were radiographically repaired. There were significant differences between the experimental groups and the control group. Conclusion RFP?loaded poly (cap?rolactone)?b?poly (lactide?co?glycolide)/β?TCP composite scaffold is expected to benefit in drug therapy and bone repair in the treatment of bone tuberculosis.

Objective To investigate the function of triggering receptor expresses on myeloid cells receptor-1 (TREM-1) in lymphocyte differentiation and regulation of Aspergillus infected immunosuppressed rats.Methods Cyclophosphamide (CTX) was intraperitoneally injected and Fumigatus spore suspension was inhaled by percutaneous tracheostomy to establish the immunosuppressive invasive pulmonary aspergillosis (IPA) rat model.After 24 h, 48 h, 72 h and 96 h inoculation, rats were sacrificed.Lung tissue specimens, bronchoalveolar lavage fluid (BALF) , and plasma samples were collected.Plasma and BALF sTREM-1, plasma T cell-specific transcription factor (T-box expressed in T cells, T-bet) and eomesodermin(Eomes) were detected by ELISA.Biopsy specimens of lung tissue were used for periodic acid-schiff (PAS) staining and culture.Results The mortality rate of immunosuppressed rats after Aspergillus inhalation for 96 h was as high as 54.4%.Biopsy of lung tissue suggested acute inflammatory cell infiltration, interstitial lung congestion, alveolar structural damage, and visible Aspergillus hyphae in alveoli.Compared with normal control group[(110.50 ± 7.70)ng/L], plasma sTREM-1 in study groups were significantly increased [IPA : (146.77 ± 10.41) ng/L;CXT + IPA at 24 h : (226.00 ± 11.88) ng/L;CTX + IPA at 48 h : (200.77 ± 10.63) ng/L;P < 0.05], so were T-bet levels [IPA : (561.17 ± 7.23) μg/L;CXT + IPA at 24 h : (647.00 ± 33.03) μg/L;CTX + IPA at 48 h : (619.23 ± 87.44) μg/L;control group : (340.03 ± 26.32) μg/L;respectively, P <0.05].However, plasma Eomes levels in IPA group, CTX + IPA at 24 h and 48 h were significantly lower compared with that in normal controls [IPA : (7.96 ± 0.65) ng/L;CXT + IPA at 24 h : (3.97 ± 0.35) ng/L;CTX + IPA at 48 h : (4.00 ± 0.74) ng/L;control group : (8.38 ± 0.51) ng/L;respectively,P <0.001].Compared with those in CTX + IPA vaccination after 24 h and 48 h, plasma sTREM-1 [(106.67 ±7.64)ng/L;(133.27 ± 32.79) ng/L] and T-bet [(299.64±63.07)μg/L;(398.02 ± 109.22) μg/L] in CTX + IPA at 72 h and 96 h inoculation were significantly lower (P < 0.001).While Eomes [(8.38 ± 0.54) ng/L;(8.40 ± 0.70) ng/L] raised significantly higher (P < 0.001).Compared with the control group, sTREM-1 levels in BALF of IPA + CTX 24 h, 48 h, 72 h, and 96 h groups were consistently high (P < 0.05).Pearson correlation analysis showed that sTREM-1 and T-bet had a significant positive correlation (r =0.91, P < 0.001), yet Eomes was negatively correlated with them (r =-0.788, P < 0.001).Conclusions sTREM-1 in rat plasma and BALF appears highly expressed in immune compromised Aspergillus infected rat model.Plasma sTREM-1 is closely correlated with T-bet and Eomes levels, which suggests that TREM-1 may be involved in lymphocytic regulation and differentiation during fungal infection.
