Objective To observe the application effect of critical care professional nursing team applied to sequential mechanical ventilation in the treatment of chronic obstructive pulmonary disease (COPD) with respiratory failure. Methods Totally 80 patients of COPD with respiratory failure from May 2014 to April 2015 were divided into study group and control group by random number table method, 40 patients in each group. Study group was applied to critical care professional nursing team. Control group was given routine nursing. The two groups were treated for 4 weeks. The clinical indicators of positive end expiratory pressure (PEEP), pressure support ventilation (PSV), carbon dioxide partial pressure (PaCO2), oxygen partial pressure (PaO2), forced expiratory volume in one second (FEV1), heart rate, arterial systolic blood pressure, respiratory rate in two groups were compared. The clinical indicators such as the duration of the stay, the duration of the total ventilation, and the time of invasive ventilation, etc, in two groups were compared;and nursing satisfaction was also compared. Results Before nursing, there were no statistical differences between the study group and the control group in PaCO2, PaO2, FEV1, heart rate, systolic arterial blood pressure, respiration rate and PEEP, PSV indicators (t=0.04-0.63, P>0.05). And after the intervention, the above indicators of the study group were (36.4±2.0) mmHg (1 mmHg=0.133 kPa), (94.7± 4.8) mmHg, (45.2 ± 16.0) %, (84.2 ± 4.3) beats/min, (94.2 ± 5.3) mmHg, (15.2 ± 3.0) times/min, (3.6 ± 1.2) mmHg, (10.2 ± 2.0) ml and (48.5 ± 5.3) mmHg, (88.3 ± 4.1) mmHg, (36.9 ± 14.1)%, (92.4 ± 6.2) beats/min, (110.4 ± 6.2) mmHg, (20.9 ± 4.1) times/min, (4.2 ± 1.6) mmHg, (13.9 ± 2.4) ml in the control group. The differences were statistically significant (t=4.37-13.51, P<0.01). After nursing care, the study group of patients with clinical indicators such as admission time, total duration of ventilation, the time of invasive ventilation were (12.5±1.5) d,(10.2±2.6) h,(5.2±2.1) h,while (18.2±2.6) d,(15.9±1.1) h,(7.9±2.9) h in the control group, the differences were statistically significant (t=12.01, 12.77, 4.77, P<0.01).The nursing satisfaction rate was 80.0% (32/40) in the study group while 62.5% (25/40) in the control group, the difference was statistically significant (χ2=6.30, P < 0.01). Conclusions Sequential mechanical ventilation therapy and nursing care in patients with COPD can significantly improve the clinical symptoms, improve nursing satisfaction, it is worthy of clinical promotion.

Objective To evaluate the effectiveness of loop electrosurgical excision procedure(LEEP) for the management of cervical intraepithelial neoplasia(CIN) grade Ⅱ. Methods A total of 28 patients were pathologically diagnosed as having CIN grade Ⅱ by colposcopic cervical biopsy.High-risk human papillomavirus(HPV) DNA testing showed positive results in 96.4% of the patients(27/28).The procedure was conducted under surface anesthesia.A loop electrode was used to cut through the cervical tissues,and then a square-shaped electrode or a small-sized loop electrode was utilized to complete the resection of lesions,including parts of the cervical canal.All the patients were followed postoperatively. Results The intraoperative blood loss was 0~20 ml,and the operation time was 5~10 min.Out of the 28 patients,postoperative abnormal vaginal bleeding was found in 3 patients.No other complications occurred.The resected tissues showed no obvious charring changes.The lesions of CIN completely disappeared in 15 patients(53.6%),subsided to grade Ⅰ in 5 patients,remained in grade Ⅱ in 5 patients,and progressed to grade Ⅲ in 3 patients.Follow-up examinations in the 28 patients for 6~24 months(mean,16 months) found no residual lesions or recurrence.The high-risk HPV DNA findings turned negative in 23 patients. Conclusions LEEP is a safe and effective procedure for the treatment of CIN grade Ⅱ,with advantages of little invasion,simplicity of performance,and no need of hospitalization.

Many studies show that transforming growth factor-β (TGF-β) can suppress tumor by inhibiting proliferation and dedifferentiation of cells and promoting cell apoptosis at early stage.But during the progression of tumor,its tumor-promoting action will be more and more obvious with the variation of TGF-β itself and its signal path.TGF-β signal path inhibitors have anti-tumor activity,but the clinical effects and side effects still need to be observed.

Objective:This study aimed to analyze the feasibility, safety, and efficacy of cryoablation in treating pain caused by malignant paravertebral and mesenchymal tumor. Methods:Cryoablation was performed in 31 patients with unresectable and painful malignant paravertebral and mesenchymal tumors whose pain was poorly controlled by conventional treatment methods. Tumors ranged in size from 3 cm to 20 cm. Pain experienced by the patient was assessed using the Brief Pain Inventory (BPI) at 0, 1 day, 1 week, 1 month, and 3 months post-cryoablation. Results:BPI scores were divided into two categories, i.e., the influence and the se-verity of pain. Both categories showed downward trend after cryoablation. Pain severity score significantly decreased (P=0.001, t=3.862;P=0.031, t=2.261) 1 day and 1 month after cryoablation. Pain influence score also significantly decreased (P=0.016, t=2.566;P=0.036, t=2.195) 1 day and 1 week after cryoablation. Two patients (6.45%) had mild complications, and no serious complication was ob-served. Conclusion:Cryoablation is a low-risk and well-tolerated topical treatment for pain caused by unresectable malignant paraverte-bral and mesenchymal tumors.

Objective To investigate the efficacy and safety of different acoustic power of high-intensity focused ultrasound (HIFU) in treating human pancreatic xenograft models. Methods Human pancreatic cancer cells (YY-1) were implanted subcutaneously in nude mice to establish animal models. The tumor bearing mice were divided into low-power HIFU treatment group (200 W,n=10), high-power HIFU treatment group (300 W,n=10) and blank control group (n=10). The change of tumor volume, the tumor growth rate and side effects were recorded. The apoptosis rate of tumor cells of each group was determined by TUNEL method. Results The tumor volume and the tumor growth rate of the low-power group and the high-power group were significantly lower than those of the control group (P<0.05), while no statistically significant differences in the tumor volume and the tumor growth rate existed between the low-power group and the high-power group (P>0.05). Compared with the low-power group, the incidence of side effects in the high-power group was significantly higher (P<0.05), including mainly skin burn (60%) and acoustic channel injury (20%). At the 7th and 14th day after the treatment, the apoptosis rates of tumor cells in both the low-power group and the high-power group were significantly higher than that of the control group (P<0.05), but the difference in the apoptosis rates of tumor cells was not statistically significant between the low-power group and the high-power group (P>0.05). Conclusion For the treatment of human pancreatic xenograft tumor in nude mice models, HIFU with low power is effective and safer.
