Objective To analyze the factors affecting the efficacy of postoperative radiotherapy (PORT) in node-positive non-small cell lung cancer (NSCLC). Methods 480 patients with stage N_1-N_2 NSCLC after radical surgery were retrospectively reviewed. Of them, 267 patients received adjuvant chemotherapy and 121 received PORT. All patients were grouped based on the N stage, tumor size and lymph node positive ratio (the percentage of positive lymph nodes from the detected lymph nodes, LNPR). Group 1 included patients with tumor size ≤3 cm and LNPR ≤33%, group 2 was tumor size > 3 cm or LNPR > 33%, and group 3 was tumor size > 3 cm and LNPR > 33%. The endpoints were the local recurrence free survival (LRFS) and overall survival (OS). Kaplan-Meier method and Cox's proportional hazards regression model were used for the statistic analyses. Results PORT improved the overall survival only in patients with N_2 disease. Both tumor size and LNPR significantly influenced the efficacy of PORT. The 5-year LRFS for patients with vs. without PORT in the group 1, 2 and 3 were 55% vs. 60% (χ~2 = 0.03,P-0.869), 42% vs. 50% (χ~2 =0.31,P=0.547),and 62% vs. 52% (χ~2=4.25,P=0.036), respectively;and the corresponding OS were 22% vs. 50% (χ~2 = 1.65 ,P =0. 199), 26% vs. 22% (χ~2= 0. 13,P=0.786) and 42% vs. 16% (χ~2= 15.33,P=0.000), respectively. Conclusions Tumor size and LNPR significantly impact the efficacy of PORT . For patients with stage N_2 NSCLC , PORT could improve local recurrence free survival and overall survival when tumor size > 3 cm and LNPR >33%.

Objective To study the efficacy and toxicity of the cyberknife in the treatment of medically inoperable patients with early stage lung cancer. Methods From September 2006 to July 2007,17 patients with clinical stage Ⅰ a- Ⅰ b lung cancer were treated with cyberknife at Tianjin Cancer Hospital. Of the 11 patients receiving CT guided biopsy, 3 were squamous cell cancer and 8 were adenocarcinoma. Six patients refused intrusive operation and were diagnosed by PET-CT scan. All patients were medically inoperable evaluated by a thoracic surgeon. The PTV = GTV + 3 ～ 5 mm, and the median volume of PTV was 36 cm3 (6-82 cm3 ). The median total prescription dose was 50 Gy(45-60 Gy) at 3-5 fractions. Results The median follow-up time was 7 months (3-11 months). All the patients finished the treatment and were alive by the last follow-up. Slight fatigue was the most common complain. Evaluated by CT scan, 13 were complete response and 4 were partial response. No recurrence, progression or distant metastasis occured. There were 3 patients with grade Ⅰ granulocytopenia,3 grade Ⅰ pneumonitis and 1 grade Ⅱ pneumonitis. Conclusions The cyberknife radiosurgery treatment in early stage lung cancer shows a high rate of local control and minimal toxicity. Long time follow-up is necessary to evaluate the survival data and late toxicity.

Objective:To investigate the effects of intervention mapping on cardiopulmonary function for patients with acute heart failure in compensatory period, so as to provide references for their early rehabilitation activities.Methods:A total of 90 patients with acute heart failure admitted to Fuwai Central China Cardiovascular Hospital from October 2018 to October 2019 were enrolled in the present study. They were divided into experimental group and control group according to draw-lots-method, with 45 cases in each group. The control group received the routine care and activity plan, while the experimental group implemented intervention mapping-based stage early rehabilitation program. The indicators included 6MWT, forced expiratory volume in one second (FEV 1), brain natriuretic peptide (BNP) as well as Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the intervention effects were compared between the two groups. Results:There were no significant differences in FEV 1, 6MWT, BNP and MLHFQ scores between the two groups at admission ( P>0.05). On discharge, FEV 1, 6MWT were (2.17±0.44) L, (273.09±55.80) m in the experimental group, significantly higher than (1.94 ± 0.39) L and (236.44 ± 50.99) m in the control group; the plasma BNP were (676.79 ± 78.75) ng/L in the experimental group, significantly lower than (736.05 ± 78.77) ng/L in the control group; in addition, the physical demention, emotional dimenson, other demension scores and total scores of MLHFQ in the experimental group were (65.39 ± 5.02), (67.56 ± 4.99), (66.05 ± 4.16) and (66.33 ± 2.63) points, significantly higher than (59.79 ± 5.94), (64.33 ± 5.93), (62.76 ± 4.47), (62.36 ± 2.98) points in the control group, the differences were statistically significant ( t values were 2.56-6.51, all P<0.05). Conclusions:Designing and implementing stage early rehabilitation program using intervention mapping can promote cardiopulmonary function and quality of life of patients with acute heart failure in compensatory period.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
