Lung ultrasound has been proven to have high sensitivity and specificity in the application of lung diseases, and significantly reduces the radiation exposure of children, especially in newborns, which makes it widely used in diagnosis, treatment and prognosis of childhood disease.In emergency and intensive care units, lung ultrasound can even replace chest radiographs as a routine examination method for chest lesions.However, the research of children′s lung ultrasound still falls behind the development of adult ultrasound, and there is a lack of standard procedures and specifications for children′s lung ultrasound.Therefore, this study mainly reviewed the research status of children′s lung ultrasound.
5. Antagonism of endogenous nociceptin/orphanin FQ inhibits reperfusion-induced arrhythmias by down-regulating microRNA-1 in rats
Chinese Pharmacological Bulletin 2019;35(4):556-560
Aim: To investigate the effect of endogenous nociceptin/orphanin FQ(N/OFQ) on arrhythmias induced by myocardial ischemia/reperfusion (I/R) in rats and the role of microRNA-1 (miR-1) in it. Methods: Twenty-four Sprague-Dawley rats were randomly divided into sham-operation group (Sham group), ischemia/reperfusion group (I/R group) and the pretreatment of N/OFQ receptor antagonist (UFP-101) group(U + I/R group). The model of myocardial ischemia/reperfusion was prepared by ligating the left anterior descending branch of the coronary artery of rats. The incidence and arrhythmogenic scores during reperfusion in rats were recorded and analysed. The myocardium at the risk of ischemia was collected at 120 min after reperfusion. MiR-1, GJA1 and KCNJ2 levels were detected by qRT-PCR and Cx43 and kir2. 1 protein levels were detected by Western blot. Results: Antagonism of endogenous N/OFQ could significantly reduce reperfusion arrhythmias and arrhythmogenic scores, compared with I/R group (P < 0. 01). The qRT-PCR and Western blot results suggested that compared with sham group, miR-1 expression significantly increased in I/R group(P < 0. 01), while the expression of Cx43, Cx43 mRNA and kir2. 1 decreased(P< 0. 05); compared with I/R group, pretreatment with UFP-101 led to reduction of miR-1 (P<0. 05) and rise of Cx43 and kir2. 1 (P < 0. 05). Conclusions: Endogenous N/OFQ up-regulates miR-1 and inhibits the expression of Cx43 and kir2. 1 proteins, leading to reperfusion arrhythmias in rats.

Objective To observe the clinical efficacy of bloodletting and cupping at Fengchi (GB 20) plus acupuncture in treating peripheral facial paralysis in acute stage.Method Sixty patients with peripheral facial paralysis in acute stage (disease duration ≤7 d) were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by bloodletting and cupping at Fengchi (GB 20) plus acupuncture, while the control group was treated with ordinary acupuncture. The two groups were treated once a day, 5 times a week, 2 weeks as a treatment course and 3 treatment courses in total. The House-Brackmann (H-B) facial nerve grading system was observed before and after the intervention, and the clinical efficacies in the two groups were compared. Result The total effective rate was 96.7% in the treatment group versus 93.3% in the control group, and the difference was not statistically significant (P>0.05). There were statistically significant differences in the H-B score between the two groups respectively after 2 and 3 treatment courses (P<0.05).Conclusion Bloodletting and cupping at Fengchi (GB 20) plus acupuncture is an effective approach in treating peripheral facial paralysis in acute stage.

Objective By in vitro culture of mouse macrophage cell line RAW264. 7 and primary mouse bone marrow macrophages, the expression of Siglec-1 when stimulated by ox-LDL was observed. Meanwhile, Siglec-1 was up-regulated by M-CSF and down-regulated by small interference RNA targeting Siglec-1 ( si-RNA-Siglec-1) , and the expression of chemokines and lipid uptake ability by macrophages were observed, to explore the role of Siglec-1 on macrophages in atherosclerosis. Methods LDL was oxidized by copper. According to preliminary experiment results, ox-LDL 100 μg/ml was selected as a stimulus. There were 6 experimental groups:normal control group,ox-LDL 100 μg/ml group, ox-LDL 100 μg/ml + si-RNA 2509 2 ng/ml group,ox-LDL 100 μg/ml + si-RNA 3618 2 ng/ml group,ox-LDL 100 μg/ml + M-CSF 5 ng/ml group and ox-LDL 100 μg/ml + M-CSF 10 ng/ml group. si-RNA-Siglec-1 was transfected into macrophage to inhibit the expression of Siglec-1, whereas M-CSF 10 ng/ml or 5 ng/ml were added into the culture medium to enhance the expression of Siglec-1. Quantitative real-time polymerase chain reaction ( qRT-PCR) was used to determine the interfere efficiency of si-RNA-Siglec-1 or M-CSF. After stimulation with ox-LDL for 48 h, cell culture supernatants were collected to determine MIP-1 alpha, MCP-1 and IL-8 concentration by ELISA (n =3 for each group) to evaluate the activation of macrophages. Internalization of lipid particles by macrophages was analyzed by oil red 0 staining. Results Observed by fluorescence microscope, si-RNA-Siglec-1 could be effectively transfected into macrophages with a transfection efficiency about 90% ;PCR results showed that si-RNA 2509 and si-RNA 3618 in a concentration of 40 pmol/L had an inhibition rate of 0. 54 ±0. 11 or 0. 52 ±0. 16 vs 1. 00 ±0. 24 (control group) , t =5. 227 and 4. 992, respectively, all P < 0.01, while M-CSF 10 ng/ml could increase Siglec-1 mRNA expression approximately 4-fold (4. 16 ± 1. 25 vs 1.00 ±0. 24, t =7. 448, P<0. 01). The secretion of MCP-1, MIP-1 alpha, and MIP-2 in si-RNA3618-Siglec-1 group [(359. 28±47. 80) pg/ml, (33. 76 ± 14. 28) ng/ml and (7.87±1.55) ng/ml for MCP-1,MIP-1 alpha, and MIP-2, respectively] was significantly reduced in compare with ox-LDL 100 μg/ml group [ (577. 89 ± 35. 95 ) pg/ml, (69. 17 ± 11. 82) ng/ml and (12.28 ± 1.19) ng/ml for MCP-1, MIP-1 alpha, and MIP-2, respectively], with P value of 0.01, 0.05 and 0.01. In contrary, ox-LDL 100 μg/ml plus M-CSF 10 ng/ml group could significantly promote macrophage chemokine secretion [ (672. 89 ± 43.80) pg/ml, (101.31 ±24.17) ng/ml and (14.81 ±0.54) ng/ml for MCP-1, MIP-1 alpha, and MIP-2, respectively], with P < 0.05 compared with ox-LDL 100 μg/ml group. Meanwhile, lipid intemalization and foam cell formation was inhibited in si-RNA3618-Siglec-l group while ox-LDL 100 μg/ml plus M-CSF 10 ng/ml group could enhance the phagocytosis of ox-LDL by macrophage. Conclusions Siglec-1 may served as a potential phagocytic receptor for ox-LDL involving in macrophage uptake of lipid and turn into foam cells. Furthermore, it can active macrophages and enhance the secretion of MIP-1 alpha, MCP-1 and IL-8, attracting more macrophages and lymphocytes to the site of inflammatory plaque. Targeted inhibition of Siglec-1 reduces macrophage uptake of lipid and secretion of chemokines. Siglec-1 may possibly serve as a potential target of treatment or delay the development of atherosclerosis.

Objective To investigate the diagnosis and treatment of gastric stromal tumor(GST). Methods Retrospective analysis was made on the clinical data of 18 cases of GST. The diagnosis of 18 cases was confirmed by pathology. Local resection of the tumor was performed in 2 cases,partial gastrectomy in 5 cases, subtotal gastrectomy in 9 cases, and total gastrectomy with lymph node clearance in 2 cases. Results Most of the patients were over forty years old.In 55.5% of cases,the location of tumor was at the middle of the stomach,and 61.0% of cases were intragastric growth type.The preoperative diagnostic rate was 27.8%,misdiagnostic rate was 72.2%.The resectability rate was 100%. No postoperative complications and operative death occurred in this series. Fifteen cases were followed up for 1 to 10 years. During follow up,2 cases died of recurrence of the tumor, and the other patients were still alive. Conclusion The GST patients lack typical clinical manifestations, and the preoperative diagnosis is difficult.Barium meal examination and gastroscopy are the main supplementary examinations.A combination of histological and immunohistochemical examinations is helpful to confirm the diagnosis.Surgical resection is the only effective therapeutic method.
