Objective To investigate the effect of mifepristone on the activity of proliferation and the apoptosis, the expression of estrogen receptor (ER),progesterone receptor (PR) protein and morphology changes of human ovarian carcinoma cell line 3AO and SKOV3 in vitro. Methods The proliferative activity of 3AO and SKOV3, which were cultured in vitro, was measured by tetrazolium-based colorimetric assay (MTT assay). Flow cytormetry (FCM) was used to measure the expressive rate of ER, PR , p53 protein, bcl-2 protein, cell apoptotic rate and cell proliferative cycle of 3AO cells, which were cultured with different concentration and duration of mifepristone. The morphologic and ultrastructure changes of apoptotic 3AO cells was observed by the light and electron microscopy. Results Mifepristone inhibited significantly the proliferation of 3AO cells in dose-time dependent manner in vitro. The inhibitory rate of 3AO cells growth, which were cultured with different concentration of mifepristone( 5,10,20,40,80 ?mol/L) and duration (24,48,72 h) was from 1.7% to 75.0%(P0.05). 3AO cells apoptosis activity appeared the positive correlation with the dose of mifepristone and cultured duration (P

Objective To explore the effect of flexible laser endotracheal intubation optical device (patent number 201520785723.7) on oral and maxillofacial intubation operations. Methods Forty-two patients with the oral and maxillofacial intubation optical device for general anesthesia were included in this study. The patients were from 16 to 73 years old and ASAⅠ-Ⅱ. Surface anesthesia was prepared for airway and nasal cavity. There were 27 patients whose mouth opening were smaller than 3 cm. After intravenous injection of midazolam 0.05 mg/kg and sufentanil 0.2μg/kg, reinforced endotracheal tube was inserted into throat 13-15 cm, then the probe shape to 120° and optical device were placed into the tube respectively, guided the tube according to the light spot in front of neck. There were 15 patients whose mouth opening were not smaller than 3 cm. The quick guidance optical device and larygoscope were adopted to help the intubation. After intravenous injection of midazolam 0.05 mg/kg, sufentanil 0.5 μg/kg, propofol 2 mg/kg, cisatracurium 0.2 mg/kg, the reinforced endotracheal tube was inserted into the oral cavity nasally, and completed intubation with laryngoscope. The success rate of intubation, time of intubation, the real-time blood pressure before and after intubation, heart rate and related complications were recorded before intubation and after intubation. Results In the 42 patients, 41 patients were successful for guidance intubation, and the success rate of intubation was about 97.6%. The average intubation time was(124.5±38.2) seconds. The shortest intubation time was 12 seconds and the longest was 276 seconds. During intubation, the increases of blood pressure and heart rate were in the normal range (<30%). Levels of SpO2 were maintained at 0.92-1.00. All the patients were without agitation. There were no serious complications such as hoarseness and pharyngalgia after operation.Conclusion The flexible laser endotracheal intubation optical device can be used quickly for oral and maxillofacial intubation, and the 45° bevel design for optical device can form two kinds of zones with bright light upward and downward. It is a new tool for nasal intubation that is more convenient for location of light guidance, and has high success rate and small stimulation.

Objective To discuss the feasibility and clinical value of percutaneous transluminal stenting (PTS) for the treatment of central venous obstruction (CVO) in hemodialysis patients with arteriovenous fistula (AVF).Methods The clinical data of 10 hemodialysis patients with AVF complicated by CVO were retrospectively analyzed.Clinically,all patients presented as swollen hand syndrome.Preoperative or intraoperative digital subtraction angiography (DSA) was performed to determine the obstruction site,and based on the disease condition the appropriate surgical approach was employed.For patients having thrombus formation,catheter-directed thrombolysis (CDT) was carried out first.For patients having severe stenosis or occlusion of veins,pre-expansion with small diameter balloon was employed before PTS.For the remaining patients,PTS was directly performed.All patients were regularly followed up after operation.Results DSA showed that brachiocephalic vein occlusion and/or occlusion or stenosis of subclavian vein,internal jugular vein and superior vena cava were observed in 5 patients who had history of internal jugular vein catheterization,while localized severe stenosis of medial segment of AVF-side subclavian vein was detected in the other 5 patients who had no history of internal jugular vein catheterization.The technical success rate of PTS was 100％ (10/10).A total of 19 stents were implanted in the 10 patients.Seven months after the treatment,one patient developed in-stent re-stenosis,and PTS had to be carried out again.Primary patcncy rates at 6 months and 12 months after the treatment were 100％ (8/8) and 75％ (3/4) respectively.Conclusion In hemodialysis patients with AVF,CVO is mainly characterized by obstructive or severely stenotic lesions.PTS carries higher success rate with satisfactory short-term and mid-term effect,its complications are slight and mild,and the technique is safe and feasible.Therefore,PTS can be used as the preferred treatment method.

To determine the effect of straight-leg-raising (SLR) movement on epidural fibrosis after laminectomy, 40 adult New Zealand rabbits were selected as laminectomy models in the study. They were divided into 2 groups: a SLR group (group S) and a control group (group C) randomly, with each group having 20 animals. All rabbits were subjected to total laminectomy in the site of S1. Every 5 rabbits in each group selected randomly were killed at the 1st, 2nd, 4th, and 8th week after the surgery. Segments of spines from L7 to S2 were removed en bloc. After gross evaluation, specimens were sliced up. The slices were stained by HE and Masson's trichrome methods respectively for histological examination. Our results showed that formation process of scar in group S was retarded as compared with that of group C at the time of the 2nd-week, but there was no statistical difference between groups in the adhesion degree (P> or =0.05). At the 4th and 8th week, the epidural fibrosis of group S was more serious than that of group C. Since the 2nd-week, the area of scar in group S was larger than that of group C. The number of fibroblasts and inflammatory cells in group S were larger than those of group C at early stage. But in later stage, there was no statistical significance between the two groups. It is concluded that SLR movement after laminectomy may promote the formation of epidural fibrosis and retard the maturity of scar. SLR movement can also aggravate scar adhesion.
