Lung cancer， the most common malignant tumor， is characterized by a complex pathogenesis and high malignancy， and poses a significant threat to the health and lives of affected individuals. p53 signaling pathway plays a crucial role in the progression of lung cancer and is considered one of the potential targets for targeted therapy. In recent years， multiple studies have indicated that traditional Chinese medicine （TCM） can exert anticancer effects by modulating the p53 signaling pathway. Based on this， this article systematically summarizes the current status and progress of research on TCM intervening in lung cancer by regulating p53 signaling pathway. It was found that TCM formula and preparations， such as Qingjin desheng tablet， Tiaoqi xiaoji decoction， Bufei tongluo jiedu formula， Jianpi bushen formula and Yiqi fuzheng jiedu formula， can promote autophagy and apoptosis of lung cancer cells， inhibit the growth and metastasis of lung cancer cells and strengthen the immune function of the body by activating p53 signaling pathway， thereby inhibiting lung cancer. TCM monomers， such as pseudoginsenoside-Rh2， saikosaponin D， polyphyllin Ⅶ， dendrobiine， sophoridine， gambogic acid， triptolide and triptolide succinate monoester YJ-4， can accelerate cell apoptosis， inhibit the proliferation of lung cancer cells and regulate cell cycle by activating p53 signaling pathway， thereby inhibiting lung cancer.

Objective:To explore the different design of readiness assurance process (RAP) and application in TBL teaching of rehabilitation medicine, and to compare the teaching effects.Methods:A total of 40 students who had clinical rotation in our department were chose as research subjects, and they were taught with TBL teaching. Two chapters of "Stroke Rehabilitation" and "Spinal Cord Injury Rehabilitation" were chosen for the two lectures. During the course of "Stroke Rehabilitation", the RAP adopted open-ended questions, and the application part simulated Teamwork meetings. In the course of "Spinal Cord Injury Rehabilitation", the RAP used close-ended multiple-choice questions, and the application part simulated making rehabilitation plan. At the end of the two lectures, questionnaires were send to students.Results:For the RAP part, more students preferred open-ended questions. In the application part, students preferred to make rehabilitation plan.Conclusion:The process of clinical diagnosis and treatment and the formulation of rehabilitation plan in clinical practice of rehabilitation medicine has been applied to different parts of TBL teachings, and students are favor of this teaching method, which provides a reference for the future TBL teaching design of rehabilitation medicine.

Objective To evaluate the value of multislice spiral computed tomography angiography (MSCTA) in differential diagnosis between epithelial ovarian carcinoma (EOC) and borderline epithelial ovarian tumor (BOT).Methods The MSCTA images of 39 EOC patients and 23 BOT patients confirmed by surgical pathology were reviewed retrospectively.Main characteristics of tumor vessels were analyzed: the number of feeding arteries, the existence of dilated draining veins, whether the tumor vessels were tortuous, whether the distribution of tumor vessels were disturbed, and whether there were accompanying microaneurysms or arteriovenous malformations (AVMs).Results Two or more feeding arteries of the EOCs and BOTs were 89.7% (35/39) and 8.7% (2/23), respectively.Dilated draining veins were observed in 87.2% (34/39) of the EOCs and 4.3% (1/23) of the BOTs.The tortuosity of tumor vessels was observed in 97.4% (38/39) of the EOCs and 13.0% (3/23) of the BOTs.79.5% (31/39) of the EOCs and 8.7% (2/23) of the BOTs were complicated by microaneurysms, and 74.4% (29/39) of the EOCs and 4.3% (1/23) of the BOTs were complicated by AVMs.The characteristics of tumor vessels were significantly different between the two groups (P<0.01), with relatively high sensitivity and specificity.Conclusion MSCTA can better show the distribution, number and pattern of tumor vessels and is of great value in differential diagnosis between EOC and BOT.

Objective To analysis the effect of salbutamol combined with noninvasive ventilator on TNF-α,IL-6,IL-8 and serum CK-MB activity in patients with chronic obstructive pulmonary disease with respiratory failure.Methods 60 patients who were diagnosed with chronic obstructive pulmonary disease with respiratory failure were collected.All patients were randomly divided into experimental group and control group,30 cases in each group. Patients in the control group received noninvasive ventilator treatment, patients in the experimental group were given salbutamol treatment on the basis of control group treatment, after the treatment, the serum levels of TNF-α,IL-6,IL-8 and serum CK-MB activity were detected in all patients.Results After treatment, compared with control group, the serum level of TNFαwas lower in the experimental group,and the difference was statistically significant(P<0.05); the serum level of IL-6 and IL-8 were lower in the experimental group(P<0.05); the serum CK-MB activity was lower in the experimental group(P<0.05).Conclusion The salbutamol combined with noninvasive ventilator can significantly reduce the serum levels of TNF-α, IL-6, IL-8 and serum CK-MB activity in patients with chronic obstructive pulmonary disease with respiratory failure, reduce the inflammatory reaction and reduce the myocardial damage,and have a guiding significance for clinica.

Objective To observe the effects of early rehabilitation on the motor function of post-stroke hemiplegic patients treated with intravenous thrombolysis.Methods Thirty-six post-stroke hemiplegic patients after intravenous thrombolysis with rtPA were recruited in this study.They were randomly divided into the early rehabilitation group (with the course less than three days) and the control group (with the course between three and seven days),18 cases in each group.Both group received a two-week rehabilitation programme.They were assessed using the Fugl-Meyer assessment (FMA) of up extremity,FMA of lower extremity and ADL score (modified Barthel index,MBI) before and after treatment,as well as at the 3rd month after treatment (during the following-up).Results After treatment and at the following-up,FMA scores of up extremity,FMA scores of lower extremity and MBI scores had improved significantly compared with before treatment in both groups.Furthermore,after treatment,in the early rehabilitation group the average FMA score of lower extremity and MBI score reached (23.33 ± 4.37) and (56.11 ± 22.27) respectively,significantly higher than those of the control group [(17.06 ± 4.70) and (40.00 ± 15.81) respectively].Conclusion Early rehabilitation contributes to short-term recovery of lower extremity motor function and ability in the activities of daily living in post-stroke hemiplegic patients after intravenous thrombolysis.

Objective To investigate bone mineral density ( BMD ) after filling in the bone scaffolds with anti-tuberculosis controlled-release microspheres, and provide experimental basis for decrease of the side effects of anti-tuberculosis therapy after spinal surgery.Methods The bone densitometer was used to observe the changes of bone mineral density before and after the infusion with the artificial allograft bone (Group A), the controlled release complex of the RFP controlled-release microspheres-artificial allograft bone (Group B), and RFP-artificial allograft bone complex (Group C), respectively.Results BMDs of three groups before perfusion were not different significantly [Group A:(0.191 ±0.018)g/cm2;Group B:(0.186 ±0.016)g/cm2;Group C:(0.189 ±0.018)g/cm2;P >0.05].BMDs of three groups after perfusion were not different significantly [Group A:(0.191 ±0.018)g/cm2;Group B:(0.179 ±0.023)g/cm2;Group C:(0.185 ±0.021)g/cm2;P >0.05].Conclusions RFP microspheres using ultrasonic vibration method and the porous bone were prepared to controlled-release anti-tuberculosis complex .BMD of three groups after perfusion were not influenced obviously .

Objective To explore the value ofintraoperative CT (iCT) in endoscopic endonasal surgery for pituitary adenomas.Methods A retrospective analysis was conducted in the clinical data of 37 patients with pituitary adenomas performed endoscopic endonasal surgery with assistance of iCT in our hospital from November 2012 to June 2013.The influences of iCT on surgical process and results were analyzed.Results Intraoperative scanning was performed 1 to 3 times in each patient,averaging 1.43 times.The scanning time was only 50-60 s.Among the 37 patients,iCT revealed residual tumor in 11,9 of which underwent further resection with total removal in 6 and subtotal in 3,and the tumors in the other two patients were unable to be resected because the adenomas were tenacious and adhered closely to the internal carotid artery.Finally,the rate of gross total removal increased from 70.3％ to 86.5％,rising by 16.2％.No iCT related complications and severe surgical complication occurred.Conclusion The application of iCT in endoscopic endonasal surgery for pituitary adenomas provides objective evidence for the guidance of surgical procedure and real-time judgment of surgical results,which not only leads to higher percentage of tumor removal but also eliminates the unnecessary blind surgical manipulation to increase the safety of the operation.

Objective To investigate the prognosis of two decompression approaches for cervical spondylotic myelopathy. Methods 86 cases were divided into two groups. 40 cases were underwent decompression by anterior decompression, fusion and internal fixation with titanium screws and plate and 46 cases underwent posterior single opendoor laminoplasty. To investigate the prognosis of two decompression approaches for single compressive segment, two compressive segments, three compressive segments and four compressive segments. Results All cases were followed up for 20 ～ 73 months with an average of 43 months. The mean JOA recovery rate was significant different between single compressive segment group (P ＜ 0.05), and no significant difference between two compressive segments and three compressive segments(P ＞ 0.05), and significant difference between four compressive segments groups (P ＜0.05). Conclusion For single compressive segment, the anterior surgery has a good surgical result,for two or three compressive segments, anterior and posterior surgery had same effect, for the four compressive segments, posterior surgical effect was good.
