Aim To explore the effects of tanshinone IIA on cell proliferation via G protein-coupled estrogen receptor inductive and regulative pathway in typical es-trogen receptor and G protein-coupled estrogen receptor positive T47D breast cancer cells. Methods The pro-liferation rate of T47 D cells influenced by tanshinone IIA was analyzed by MTT assay. G protein-coupled es-trogen receptor agonist G1 and GPER antagonist G15 were employed as tools. GPER SiRNA was applied to build GPER gene silence T47D cells. GPER expres-sion influenced by tanshinone IIA was measured by Western blot. Results The proliferation rates of T47D cells treated with 1 × 10 -5 mol·L-1 - 1 × 10 -7 mol· L-1 of tanshinone IIA were decreased significantly. Such effects could be attenuated by G1 or enhanced by G15 . Growth of GPER SiRNA transfected T47 D cells were significantly inhibited by 1 × 10 -5 mol·L-1 - 1 × 10 -7 mol·L-1 of tanshinone IIA treating. Result of Western blot showed that tanshinone IIA at 1 × 10 -5 mol· L-1 and 1 × 10 -6 mol · L-1 could induce de-crease of GPER protein expression in T47D cells. Conclusions Tanshinone IIA shows inhibitory effects on proliferation rate of T47 D breast cancer cells via GPER pathway. Tanshinone IIA could perform regula-tive function on GPER expression level in target cells.

Hepatocellular carcinoma ( HCC) , as one of the most common malignant neoplasms , has a relatively high morbidity and mortality rate worldwide.MicroRNAs (miRNAs),a type of comparatively conserved endogenous small non-coding RNAs, function as pivotal regulators involved in various biological functions through the post -transcriptional regulation of gene expression .Some miRNA genes are arranged into a intandem model and reside close together on the same chromosome , forming miRNA clusters . These clustered miRNAs are mostly located on polycistronic transcripts and expressed at similar levels.In the human imprinted 14q32 region, 52 miRNA genes are organized as a large cluster which spans about 220 kb of the long arm ( q) .Lines of evidence show that dysregulation of miRNAs in this cluster are involved in the development of HCC .This review summarizes the structural characteristics of 14 q32 miRNA cluster as well as its impact on HCC in initiation and progression .

BACKGROUND: Blood platelet is active commonly appeared in both acute and recovery stages in ischemic cerebral apoplexy. Cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) are closely correlated with the blood platelet function.OBJECTIVE: To observe the therapeutic effects of compound danshen drop on clinical prevention and treatment of transient cerebral ischemic attack (TIA) and the influence on serum cAMP and cGMP.DESIGN: Randomized control experiment.SETTING: Department of Neurology of Binzhou Medical College affiliatedHospitalPARTICIPANTS: Totally 180 TIA patients participated in the experiment in volunteer in the clinic of Neurological Department of Affiliated Hospital of Binzhou Medical College from September 2000 to April 2001.

Aim By establishing mouse acute myocardial infarction model,to observe the protection of isoflavones on ischemic myocardium and research the mechanism.Methods Mouse acute myocardial infarction model was established by ligating the left anterior descending(LAD)coronary artery.Danshen was used as the positive control.The effect of isoflavones on myocardial infarct area,serum myocardium creatase and serum levels of SOD and MDA was observed.By Real Time PCR,it was found that isoflavones could affect the expression of β-adrenergic receptor kinase(β-ARK_1).Results Isflovones could obviously reduce the myocardial infarct area and lower the levels of serum myocardial creatase and MDA.It could downregulate the expression of β-ARK_1 as the doses are increased.Conclusions Isoflavones can protect the myocardium of acute myocardial infarction mouse.The mechanism is related to the reduction of the oxidative damage,and the downregulation of the expression of β-ARK_1.

Objective To explore the value of iteration algorithm (AIDR 3D) and filter-back projection (FBP) combined with CT low dose scanning in evaluation of lumbar intervertebral disc hernia.Methods Totally 150 patients with lumbar degenerative osteoarthropathy were randomly divided into A＞E groups,with 30 cases in each group.Scanning parameters of A＞D groups were 120 kV of tube voltage,and 100 mAs,50 mAs,30 mAs,as well as 20 mAs of tube current.While parameters of group E were 80 kV of tube voltage and 100 mAs of tube current.Each group was reconstructed with FBP and AIDR 3D,respectively,and their noises,SNRs and CNRs of groups were compared.And 3-point evaluation method was used to score the imaging,while score ≥2 were acceptable image quantity for clinical imaging.Results Under different radiation doses,AIDR 3D reconstruction images were superior to FBP in noise,SNR,CNR and display of intervertebral disc hernia.Under the same reconstruction technology,with the reduction of dose,noise increased,SNR and display of intervertebral disc hernia decreased.Except for slightly lower in AIDR 3D reconstruction with 50 mAs than that with 30 mAs,CNR decreased with the reduction of dose.Two reconstruction technologies under the same dose,image quality of reducing the tube current were better than that of lowering the tube voltage.Conclusion It is valuable of AIDR 3D combined with CT low dose scanning in evaluation on lumbar intervertebral disc hernia.

Objective To investigate the mechanism by which Nicotinamide adenine dinucleotide(NADH)regu-lates anti-tuberculosis drug-induced liver injury and apoptosis in mice through SIRT1/Nrf2 pathway.Methods Twenty-four six-week-old SPF male mice were randomly divided into four groups according to body weight,ADLI group[90 mg/(kg·d)Isoniazid,135 mg/(kg·d)Rifampicin,315 mg/(kg·d)Pyrazinamide were given by gavage],control group[thesame volume of saline was given by gavage as antituberculosis drug-induced liver injury(ADLI)group],NADH group(30 mg/kg NADH wasgiven by gavage on the basis of control group)and NADH intervention group(30 mg/kg NADH wasgiven by gavage on the basis of ADLI group),with sixmice in each group.They were gavaged continuously for seven days,and their seruand liver tissues were collected.The mRNA and protein expression of silence information regulator 1(SIRT1),nuclear factor erythroid 2-related factor 2(Nrf2)in SIRT1/Nrf2 pathway,apoptosis indicators B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax)and caspase-3 were detected by qRT-PCR and Western blot,respectively.HE staining was performed to observe the morphology of liver tissue.The liver was weighedandthe liver index was obtained by dividingweight by body weight.The levels of glutamate aminotransferase(ALT),aspartate aminotransferase(AST)and lactate dehydrogenase(LDH),which are indicators of liver injury,were detected by microplate method.Results Compared with control group,the protein and mRNA expression of SIRT1,Nrf2decreased significantly in ADLI group.Liver tissue struc-ture wasdisturbed,hepatocytes were obviously swollen,and their boundary was unclear.The weight of mice de-creased,but liver index increased.The mRNA and protein expression level of anti-apoptotic factor Bcl-2 decreased,while that of Bax and caspase-3 was raised.The level of ALT,AST and LDH were also elevated.The differences a-bove were statistically significant(P＜0.05).Compared with ADLI group,the protein and mRNA expression of SIRT1,Nrf2 were higher after NADH intervention.Liver tissue structure became clear,and hepatocytes were po-lygonal.The protein and mRNA expression of anti-apoptosis factor Bcl-2 was elevated and while that of Bax and caspase-3 was lower.The weight of mice increased and liver index decreased.The expression of ALT,AST and LDH decreased.The differences above were statistically significant(P＜0.05).Conclusion NADH may allevi-ate anti-tuberculosis drug-induced liver injury and apoptosis in mice by regulating SIRT1/Nrf2 pathway.

Objective:To investigate the effect of ultra-low dose (ULD) computed tomography (CT) scanning on the diagnosis of ankle fractures and the quality of a three-dimensional printing (3DP) model.Methods:This study was a prospective study. A total of 61 patients with clinical ankle fractures treated conservatively in Zhuhai Hospital of Guangdong Hospital of Traditional Chinese Medicine from November 2019 to January 2022 were included in this study. Patients underwent standard dose (SD) CT scan and ultra-low dose (ULD) CT scan, respectively. The tube voltage/tube current of SD and ULD were 120 kV/100 mAs and 80 kV/10 mAs, respectively. Two senior radiologists evaluated the presence of ankle fractures. The effective radiation dose ( E), noise, signal-to-noise ratio (SNR), contrast signal-to-noise ratio (CNR), and CT value of bone cortex minus CT value of peripheral fat (CTc) were compared. The radiologists also evaluated the discoverability, diagnosability, and overall image quality of the fracture line according to Likert′s 5-point scoring method. Two senior orthopedists subjectively evaluated the quality of each 3DP model (model clarity and operation guidance). A score ≥ 3 indicated that the quality of the CT diagnostic image and 3DP model were acceptable. Results:The interval between the two CT scans was (9.23 ± 1.92) d. A total of 94 fracture sites were found. There were no missed diagnosis or misdiagnosis based on the SD and ULD scans.Noise, SNR, and CNR were better on the SD CT scanning ( F=5.92, 9.70, 8.32, P=0.00), however, CTc was higher on the ULD scans ( F=27.55, P<0.01). The image scores of the SD and ULD scans were (4.97 ± 0.18) and (4.21 ± 0.71), and the quality scores of the 3DP model (4.99 ± 0.01) and (4.87 ± 0.34), respectively. The SD scans were better than the ULD scans with respect to CT image quality and 3DP model quality ( Z=-6.88, -2.91, P<0.01), but both were considered suitable to meet clinical needs (all ≥ 3 points). The E associated with SD and ULD scannings were (34.68 ± 4.96) μSV and (1.04 ± 0.10) μSV, respectively. The latter was thus significantly better than the former ( F=38.77, P =0.00). Conclusions:The E value of ULD scanning is about 3.00% of SD scanning E, which can meet the needs of clinical diagnosis of ankle fracture and 3DP model printing diagnosis.

Objective:To investigate the effects of silicon photomutipliers (SiPM) detector and Bayesian penalized likelihood (BPL) reconstruction algorithm on semiquantitative parameters of 18F-FDG PET/CT and diagnostic efficiency for solitary pulmonary nodules/masses compared with traditional photomultiplier tube (PMT) and ordered subsets expectation maximization (OSEM). Methods:From March 2020 to January 2022, 118 patients (76 males, 42 females, age (63.0±10.1) years) newly diagnosed with solitary pulmonary nodules/masses in First Hospital of Shanxi Medical University were prospectively enrolled and underwent 18F-FDG PET/CT imaging with two different PET/CT scanners successively. The images were divided into PMT+ OSEM, SiPM+ OSEM and SiPM+ BPL groups according to PET detector and reconstruction algorithms. The SUV max, SUV mean, metabolic tumor volume (MTV) and total lesion glycolysis (TLG) of pulmonary nodules/masses were measured, then signal-to-noise ratio (SNR) and signal-to-background ratio (SBR) were calculated. One-way analysis of variance and Kruskal-Wallis rank sum test were performed to compare differences of above parameters among groups. ROC curve analysis was used to analyze the optimal threshold of SUV max for the differential diagnosis of pulmonary nodules/masses and AUCs were obtained. Results:There were 83 malignant nodules and 35 benign nodules. The image quality of SiPM+ BPL group (4.23±0.64) was better than that of SiPM+ OSEM group (3.57±0.50) or PMT+ OSEM group (3.58±0.51; F=54.85, P<0.001). There were significant differences in SUV max (7.57(3.86, 15.61) vs 4.95(2.22, 10.48)), SUV mean (4.43(2.28, 9.12) vs 2.84(1.21, 5.71)), MTV (3.54(1.57, 7.67) vs 5.09(2.83, 11.79)), SNR (28.12(12.55, 54.38) vs 20.16(8.29, 41.45)) and SBR (4.03(1.83, 7.75) vs 2.32(0.96, 5.03)) between SiPM+ BPL and SiPM+ OSEM groups ( H values: 16.63-37.05, all P<0.001). The optimal threshold values of SUV max in SiPM+ BPL, SiPM+ OSEM and PMT+ OSEM were 3.31, 2.21, 2.05 with AUCs of 0.686, 0.689, 0.615 for nodules < 2 cm, and were 10.29, 6.49, 4.33 with AUCs of 0.775, 0.782, 0.774 for nodules/masses ≥2 cm. Conclusions:Image quality and parameters of pulmonary nodules/masses are mainly affected by the reconstruction algorithms. BPL can improve SUV max, SUV mean, SBR and SNR, but reduce MTV without significant effect on liver parameters. SiPM+ BPL has a higher diagnostic threshold of SUV max than SiPM+ OSEM and PMT+ OSEM.

Objective:To compare the effects of intensive and standard blood pressure control on the outcomes of patients with acute ischemic stroke in the anterior circulation who have successfully recanalized after endovascular therapy (EVT).Methods:A multicenter, open-label, blinded-endpoint, randomized controlled design was used. Patients with anterior circulation stroke received EVT and successfully recanalized in Nanjing First Hospital, Nanjing Medical University and several branch hospitals from July 2020 to October 2022 were prospectively included. They were randomly divided into the intensive blood pressure control group (target systolic blood pressure [SBP] 100-120 mmHg) or the standard blood pressure control group (target SBP 121-140 mmHg). The blood pressure of both groups needs to achieve the target within 1 h and maintain for 72 h. The primary outcome endpoint was outcome at 90 d, and the good outcome was defined as a score of 0-2 on the modified Rankin Scale. Secondary outcome endpoints included early neurological improvement, symptomatic intracranial hemorrhage (sICH) within 24 h, and death and serious adverse events within 90 d.Results:A total of 120 patients were included, including 63 in the intensive blood pressure control group and 57 in the standard blood pressure control group. There was no statistically significant difference in baseline characteristics between the two groups. The SBP at 72 h after procedure was 122.7±8.1 mmHg in the intensive blood pressure control group and 130.2±7.4 mmHg in the standard blood pressure control group, respectively. There were no significantly differences in the good outcome rate (54.0% vs. 54.4%; χ2=0.002, P=0.963), the early neurological improvement rate (45.2% vs. 34.5%; χ2=1.367, P=0.242), the incidence of sICH (6.3% vs. 3.5%; P=0.682), mortality (7.9% vs. 14.0%; χ2=1.152, P=0.283) and the incidence of serious adverse events (12.7% vs. 15.8%; χ2=0.235, P=0.628) at 90 d between the intensive blood pressure control group and the standard blood pressure control group. Conclusion:In patients with anterior circulation stroke and successful revascularization of EVT, early intensive blood pressure control don’t improve clinical outcomes and reduce the incidence of sICH.
