Objective To evaluate the application of a puncture guidance supporter in CT guided biopsy and interventional therapy. Methods Totally 468 patients underwent CT interventional biopsy (n=110) or treatment (n=358) using a puncture guidance supporter. The size of lesions was 2-15 cm. CT scanning was performed to determine the entry point, data of bi-directional needle angle α, θ and depth d before operation. After local anesthesia, the needle was punctured into skin through the puncture guidance supporter, the needle overlap CT positioning laser line in tilt angle (α) was adjusted and the puncture direction at angle θ. After CT scanning confirmed the needle aiming at target lesion, punctures were performed with the needle into the depth to hit the target. Results The total puncture hit rate was 100%, and one step hit rate was 96.79%. The average time from location scanning to hit the target was 8.4 min. The incidence of pneumothorax occurred in thorax management was 1.56%. Conclusion The application of puncture guidance supporter in CT interventional diagnosis and treatment makes operation more accurate, safe and convenient.

Objective To investigate the protective effect of crocin on oxidative stress cell model of PC 12 cell and the effect of crocin on PI3K/Akt signal pathway,as well as further explore the mechanism of protective effect on model cells.Methods Cells were divided into control group,model group,crocin group and VE group.The cell survival rate was detected by MTT method,and the expression of mRNA and protein of PI3K/Akt were detected by RT-PCR and Western blot.Results With the crocin concentration in 0.625 μM and 5 μM,the cell survival rate increased in a dose-dependent manner.The average optical density rate of PI3K and Akt mRNA were 0.435±0.044 and 0.375 ± 0.034,and the PI3K and Akt protein were 0.378± 0.038 and 0.386± 0.043 of crocin group.Compared with the model group,the expression levels of PI3K/Akt increased in crocin group (P＜0.05).Conclusion These results indicate that the antioxidant and antiapoptosis effects of crocin are induced via increasing expression of PI3K and pAkt.

ObjectiveTo study the pathogcncsis of gastrointestinal vascular malformation (GIVM) and the potential mechanism of thalidomide in the treatment of gastrointestinal bleeding due to GIVM.Methods We collected the surgical intestinal specimens from 10 patients who suffered from massive hemorrhage of gastrointestinal tract owning to GIVM and the normal intestinal mucosa around the lesions,as well as normal intestinal mucosa from healthy subjects.Immunohistochemical(IHC) staining was carried out to investigate the differences of angiopoietin 2 ( Ang2 ),Notch1 and delta like ligand 4 (Dll4) in the above three intestinal mucosa to find the relationship with the pathogenesis of GIVM. Human umbilical vein endothelial cells(HUVECs) were cultured with 0,25,50,100 and 200 mg/L thalidomide for 24 or 48 hours to observe their mRNA and protein expressions of Ang2,Notch1,Dll4 by real-time PCR and Western blot.ResultsBy IHC staining,more expressions of Ang2,Notch1 and Dll4 in the lesions were detected than those in the normal intestinal mucosa around the lesions and the normal intestinal mucosa in healthy people.The expressions of Ang2,Notch1 and Dll4 were significantly correlated (P =0.016,r =0.732),and the expressions of Notch1 and Dll4 were absolutely correlated ( P =0.000,r =1.000).Real-time PCR and Western blot showed that thalidomide could down-regulate the expressions of them,which were in a concentration-dependent manner.ConclusionAng2,Notch1 and Dll4 may correlate with the pathogenesis of GIVM,while thalidomide can concentration-dependently down-regulate the expression of Ang2,Notch1 and Dll4,which may be one of the mechanism that thalidomide play a therapeutic role in GIVM.

Objective To synthesize 99Tcm-TP5-3 and evaluate its biodistribution and kinetics as a molecular probe for the detection of apoptosis,and evaluate tumor apoptosis after a single dose of paclitaxel chemotherapy in MDA-MB-231 breast tumor model.Methods TP5-3 was labeled with 99Tcm directly,and analyzed with HPLC.The radioactivity in tissues was measured and expressed as ％ID/g and T/NT (tumor/muscle).The mice bearing MDA-MB-231 breast tumor were divided into two groups:the treatment group which was given a single dose of paclitaxel (40 mg· kg-1,via tail vein),and the control group which was injected with the same volume of normal saline.After therapy,99Tcm-TP5-3 was injected via tail vein in both groups (100 μ1 for each mouse).MicroSPECT/CT was performed at 3 h postinjection.Radioactivity in different tissues was determined after imaging.Apoptotic cells were measured with flow cytometry.The morphological changes of the apoptotic cells were observed by light microscopies.One-way analysis of variance,two-sample t test and linear correlation analysis were used to analyze the data.Results The radiolabeling efficiency was ＞ 95％ and the radiochemical purity of 99Tcm-TP5-3 was (96.0± 1.5)％ at room temperature for 4 h.The predominant uptake was found in the kidneys at 30 min postinjection ((8.48± 1.07) ％ID/g),with rapid tracer clearance from the circulation.By comparison with activity at 5 min postinjection ((13.74± 4.21) ％ID/g),85％ of the initial activity reduced in blood at 4 h ((2.07±0.35) ％ID/g; F=11.310,P＜ 0.05).99Tcm-TP5-3 was mainly accumulated in the kidneys,liver and stomach,and excreted via the kidneys.T/NT in the treated group was 4.21±0.06,which was significantly higher than that of the control group (1.57±0.67; t =12.820,P＜0.05).The radioactivity of tumor tissue in the treatment group was much higher than that in the control group (4.82±0.54) ％ID/g vs (1.44±0.38) ％ID/g,t=0.679,P＜0.05).The tumor uptake of 99Tcm-TP5-3 in the treatment group positively correlated well with the apoptotic cells (r =0.985,P＜0.05).Histopathology further confirmed that a large number of apoptosis had occurred in the tumor after paclitaxel treatment.Conclusion 99Tcm-TP5-3 appears to have potential to be a useful molecular probe for imaging tumor cell apoptosis.

This study was aimed to investigate the diuretic effect ofMori Cortex and to identify effective fractions inM. Cortex. Metabolic cages were used to firstly observe the diuretic effect ofM. Cortex aqueous extracts on rats. Medications were continuously given for 5 days to screen for the best dosage of diuretic effect. Picric acid assays were used to detect creatinine levels in serum and urine after 5-day medication. Then, the diuretic effect of each chemical split fraction inM. Cortex was studied in order to indentify the effective parts. The results showed that after administration ofM. Cortex aqueous extracts for 3 to 5 days, compared with the control group, there was a significant diuretic effect on rats (P<0.05 orP<0.01). And the medium-dose ofM. Cortex aqueous extracts showed the best effect (P<0.01). However,M. Cortex aqueous extracts had no significant effect on creatinine levels in serum and urine. Assays of diuretic effect of chemical split fractions ofM.Cortex indicated that compared with the control group, 30% ethanol fraction and fatty oil fraction had the best diuretic effect (P<0.01). It was concluded thatM.Cortex aqueous extracts had a significant diuretic effect. And the chemical fractions contributed mostly to this effect were mainly existed in the 30% ethanol fraction and fatty oil fraction.

Medical data involves patients'privacy and is an important factor in the healthcare of our nation's people.However,in recent years,with a serious of development trends such as mobile office and cloud-based storage of medical data,the risk of data leakage has further increased.In order to effectively deal with this phenomenon and ensure the security of patients'medical data to the greatest extent,Shantou Central Hospital has established a medical data security system in both managerial and technological dimensions through domestic Cloud Native technology to achieve the security control of the total life-cycle of data,providing a practical application-level solution for the construction of a systematic data security system.
