Objective To investigate the value of Adobe Photashop images software in the verifica-tion of radiation portal. Methods The portal and simulation films or CT reconstruction images were impor-ted into computer using a scanner. The image size, gray scale and contrast scale were adjusted with Adobe Photoshop images software, then image registration and measurement were completed. Results By the com-parison between portal image and simulation image, the set-up errors in right-left, superior-inferior and ante-rior-posterior directions were (1.11 ± 1.37) mm, (1.33 ± 1.25) mm and (0.83±0.79) mm in the head and neck;(1.44±1.03) mm,(1.6±1.52) mm and (1.34±1.17) mm in the thorax;(1.53±0.86) mm, (1.83 ± 1.19) mm and (1.67 ± 0.68)mm in the abdomen; (1.93 ± I. 83) mm, (1.59 ± 1.07)mm and (0.85 ± 0.72)mm in the pelvic cavity. Conclusions Accurate radiation portal verification and posi-tion measurement can be completed by using Adobe Photoshop, which is a simple, safe and reliable method.

Objective:To survey the first-aid ability of general practitioners (GPs) and the emergency service capacity of primary health institutions in southern Zhejiang province.Methods:The questionnaire of first-aid ability of GPs in primary care institution was developed on the basis of the Delphi method during August to October 2018. The questionnaire was employed in a survey on the first-aid ability among 480 GPs from 169 community health service centers of three regions in southern Zhejiang province. The survey covered basic information and first-aid skills and emergency response ability of GPs, and the emergency facilities of primary health institutions.Results:A total of 480 questionnaires were distributed and 447 were retrieved with an recovery rate of 93. 1%(447/480). Among the 447 responders, 55.9% (250/447) were males, 70.9% (317/447) had bachelor′s degree or above, and 60.2% (269/447) had middle and senior professional titles. There were 99.6% (445/447), 86.6% (387/447), 76.1% (340/447) and 69.8% (312/447) responders considered cardiopulmonary resuscitation(CPR), electrical defibrillation, respiratory balloon and endotracheal intubation as important first-aid skills, and corresponding mastery rates were 84.3% (377/447), 32.0% (143/447), 55.2% (247/447) and 12.9% (58/447), respectively. The 92.4% (413/447) responders thought that the rescue ability of common emergency and critical illness was the most important, while only 32.4% (145/447) responders mastered it. Least responders [41.4%(185/447)] thought that ability of using bedside ultrasound was important, and the corresponding mastery rate was only 3.8%(17/447); 77.4%(346/447) of general practitioners believed that CPR machines was important, while the available rate of CPR machines in primary health care institutions was only 16.0%(27/169).Conclusion:The GPs in southern Zhejiang province have a good grasp of cardiopulmonary resuscitation skills, but have a low mastery rate of first-aid skills such as electrical defibrillation, tracheal intubation, and emergency rescue capabilities, which are quite different from their perceived importance evaluation.

OBJECTIVE: To explore the influence of gender of chromosomal translocation carriers on the occurrence of embryonic chromosomal aberrations. METHODS: A retrospective study was carried out. Data were collected from 235 couples carrying reciprocal translocations (1163 blastocysts) and 70 couples carrying Robertsonian translocations (351 blastocysts). The preimplantation genetic testing for structural rearrangement (PGT-SR) analysis of 1514 blastocysts were completed through next generation sequencing (NGS). RESULTS: After adjusting the confounding factors such as female age, AMH, ovarian stimulation regimen, and Gn dosage, the results showed that the risk for blastocyst chromosomal abnormalities was 0.41 [OR(95%CI), 1.41(1.06, 1.87), P < 0.05] times higher in female reciprocal translocation carriers and 1.02 [OR(95%CI), 2.02 (1.20, 3.40), P < 0.01] times higher in female Robertsonian translocation carriers compared with male carriers, respectively. Compared with male carriers, the risk of blastocyst chromosomal abnormalities was increased by 0.67 times [OR(95%CI), 1.67 (1.10, 2.56), P < 0.05] in female reciprocal translocation carriers over 30 years old and 1.06 times [OR(95%CI), 2.06 (1.02, 4.15), P = 0.0434, P < 0.05] in female Robertsonian translocation carriers between 25 and 30 years old. CONCLUSION Compared with male carriers, female carriers of reciprocal or Robertsonian translocations have a higher risk for producing embryos with chromosomal abnormalities, and their age may also be a risk factor.

Objective:To construct an intervention program of sports and medical integration for patients with acute myocardial infarction (AMI) in phase Ⅱ cardiac rehabilitation, so as to provide reference for the effective implementation of physical activity behavior change in AMI patients during phase Ⅱ cardiac rehabilitation.Methods:Before the research, we browsed relevant literature and guidelines published from July 2016 to June 2021, made a retrospective study on the influencing factors of cardiac rehabilitation behavior for AMI patients, and carried out a qualitative interview on cognitive and compliance motivations for AMI patients. Furthermore based on trans-theoretical model, the first draft of the intervention program was developed and and the expert consultation questionnaire was formed. From February to April 2022, Delphi method was used in 16 experts from 10 hospitals and 1 nursing college in 4 provinces. After 2 rounds of expert consultations on the importance and operability of items, the intervention program was finally determined.Results:The effective recovery rates of the 2 rounds of expert consultations questionnaires were both 16/16. The authority coefficient of expert consultation was 0.90, the judgment basis coefficient was 0.96, and the familiarity degree was 0.84. After the second round of expert consultation, the coefficient of variation of the importance of each item was (0.0-13.4)%, and the coefficient of variation of operability was (0.0-18.1)%. The final intervention program of sports and medical integration for patients with AMI in phase Ⅱ cardiac rehabilitation had 37 items, containing precontemplation stage (8 items), contemplation stage (7 items), preparation stage (5 items), action stage (9 items) and maintenance stage (8 items).Conclusions:The construction process of the intervention program of sports and medical integration for patients with AMI in phase Ⅱ cardiac rehabilitation is scientific and feasible. The content is focused on the patient-centred conception and the whole-process management for the exercise rehabilitation of AMI patients in phase Ⅱ cardiac rehabilitation. This intervention program may improve the safety, feasibility, participation and compliance in phase Ⅱ cardiac rehabilitation in patients with AMI. So it is recommended to be popularized and used in phase Ⅱ cardiac rehabilitation.

Objective To evaluate Chinese nurses' perception of the nursing work environment and to compare the differences among the eight economic regions in mainland China.Thus,policy-makers and nursing managers can optimize and coordinate resources based on the results of this study.Methods Chinese version of Nursing Working Environment Scale was used in the study.A total of 19,000 nurses from 31 provinces and municipalities in mainland China were investigated.Descriptive analysis,cluster analysis and nuclear density estimation were conducted.Results The average score of the nursing work environment was 4.1 points,which means nurses were somewhat satisfied with their work conditions.Specifically,nurses were most dissatisfied with the basic safeguard dimension (3.4 points),followed by sufficient manpower (3.9 points),career development (4.0) and leadership and management(4.0)dimensions.In addition,the eight economic regions could be divided into three categories(P＜0.01)according to the differences of the nursing work environment.The first category included the northeast,northern coastal and middle reaches of the Yellow River economic zone;the second category included eastern coastal economic zone;and the third category included the southern coast,the middle reaches of the Yangtze River,southwest and northwest economic zone.Conclusion The development of the nursing work environment in the vast majority of mainland China is unbalanced and the regional differences are obvious.

: To explore the potential associations between perceived stress and health-promoting behaviors based on the theoretical schema of the middle-range theory of adaptation to chronic illness. From January to May 2021, a convenience sampling method was used to recruit 230 young and middle-aged patients with metabolic syndrome who underwent physical examination in the inpatient center of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. The Health-Promoting Health Profile-Ⅱ, Chinese Perceived Stress Scale, Coping and Adaptation Processing Scale-Short Form, and Multi-dimensional Scale of Perceived Social Support were used in the cross-sectional study. The chain mediation effect procedure and bootstrap sampling test were used to examine the mediating role of adaptability and social support between perceived stress and health-promoting behaviors. The mean score of health-promoting behaviors was 100.0±14.6, the mean score of perceived stress was 22.0± 6.9, the mean score of adaptability was 47.0±6.1, and the mean score of social support was 63.8±10.8. Perceived stress had a negative impact on patients' health-promoting behaviors (=-0.309, <0.05). The adaptability (effect size= -0.112, 95%:-0.199~-0.038) and social support (effect size= -0.032, 95%:-0.083~played a mediating role and a chain mediating role in the process of perceived stress influencing patients' health-promoting behaviors (effect size= -0.045, 95%:-0.093~-0.020). Adaptability and social support play an intermediary role between perceived stress and health-promoting behaviors in young and middle-aged patients with metabolic syndrome. Healthcare professionals can motivate patients to develop healthy behaviors by developing intervention strategies on adaptability and social support.

Objective: To investigate the assessment and treatment strategy of patients with renal cell carcinoma. Methods: The clinical data of 43 patients with renal cell carcinoma and bone metastases admitted to the First Affiliated Hospital of Nanjing Medical University from January 2006 to December 2018 were retrospectively analyzed. The follow-up time was 6 years, with an average age of 55.4 years (21-87 years). There were 29 males, 14 females, 22 cases of limb bone metastasis, 12 cases of spinal metastasis, 9 cases of multiple bone metastasis, 21 cases of Fuhrman grade 1 and 2, 19 cases of T₁, and 20 cases of N₀. All patients were confirmed by postoperative pathological examination or imaging data suggesting that bone metastasis are from renal cell carcinoma. Forty-three patients underwent primary renal surgery, and molecular targeted therapy was used after the operation. The treatment process was smooth, no obvious discomfort, and postoperative pathology showed clear cell carcinoma.22 patients with limb bones metastasis and 12 patients with spinal metastasis included in the study all met the indications for secondary surgery after the disease assessment. After communicating with the patient, 13 patients with limbs metastasis and 6 patients with spinal metastasis received local treatment, including complete resection of the extremities and spinal fixation, the remaining 15 patients and 9 patients with multiple bone metastasis were treated conservatively. There were 19 patients in the local treatment group, 13 patients with limbs bone metastasis, 6 patients with spinal bone metastasis, the average age was 54.9 years, the average diameter of the primary tumor was 4.7 cm. There were 24 patients in the conservative treatment group, 9 patients with limbs metastasis, 6 patients with spinal metastases and 9 cases with multiple bone metastasis, with an average age of 56 years and a primary tumor diameter of 5.6 cm. Limb metastatic lesions were evaluated according to the patient's general condition, bone pain, fracture risk, and bone metastasis. Spinal lesions were evaluated according to Tokuhashi score, Harrington score, Tomita score, vertebral stability assessment, and molecular targeted therapy. Aminokinase inhibitors, conservative treatment with local radiotherapy and bisphosphonate treatment. Results: During the follow-up period, the 1-year overall survival rate of the local treatment group was 100.0%, the 2-year overall survival rate was 89.4%, and the 5-year overall survival rate was 73.7%. The 1-year overall survival rate of the conservative treatment group was 87.5%, and the 2-year overall survival rate was 62.5%. The 5-year overall survival rate was 16.7%. The 2-year and 5-year survival rates of the local treatment group were statistically different (P=0.044, P=0.000) compared with the conservative treatment group. For patients with limb bone metastasis, the 5-year survival rate was significantly higher in patients receiving topical treatment than in the conservative treatment group (P=0.011). For spinal metastasis, spinal pain in the local treatment group was alleviated to varying degrees. No spinal instability and spasticity were observed after follow-up. In the spine patients who received conservative treatment, 3 patients developed paraplegia, which was statistically different from local treatment (P=0.046). Another 9 patients with multiple bone metastases did not undergo local surgery, and all died after multiple organ failure. Conclusions At the same time of molecular targeted therapy, according to the evaluation results, selective treatment of bone metastases with secondary surgical indications, including complete resection of the extremities and spinal fixation, can significantly improve the survival and quality of life of those patients.

Objective To investigate the molecular mechanism of taurine regulating the polarization of M2 macrophages by mitophagy. Methods THP-1 cells were divided into four groups: M0 group (THP-1 cells were treated by 100 nmol/L phorbol myristate ester for 48 hours to polarize into M0), M2 group (THP-1 cells were induced to polarize into M2 macrophages by 20 ng/mL interferon-4 (IL-4) for 48 hours), M2 combined with taurine groups (added with 40 or 80 mmol/L taurine on the basis of M2 macrophages). The mRNA expression of mannose receptor C type 1(MRC-1), C-C motif chemokine ligand 22(CCL22) and dendritic cell-specific ICAM-3 grabbing non-integrin (CD209) in M2 macrophages were detected by quantitative real-time PCR. Mitochondrial and lysosome probes were used to detect the number of mitochondria and lysosomes by multifunction microplate reader and confocal laser scanning microscope. The level of mitochondrial membrane potential (MMP) was detected by JC-1 MMP assay kit. The expression of mitophagy-related proteins PTEN-induced putative kinase 1 (PINK1) and microtubule-associated protein 1 light chain 3 (LC3) were detected by Western blot analysis. Results Compared with M0 group, the expression of MRC-1, CCL22, CD209 and PINK1, the number of mitochondria and the level of MMP in M2 group were significantly increased, whereas the number of lysosomes and LC3II/LC3I ratio were decreased. Compared with M2 group, the expressions of MRC-1, CCL22 and CD209, the number of mitochondria and the level of MMP in M2 combined with taurine group dropped significantly while the number of lysosomes was found increased, and the protein expression of PINK1 and LC3II/LC3I ratio were also increased. Conclusions The polarization of M2 macrophages is regulated by taurine to prevent excessive polarization via reducing the level of MMP, improving the level of mitophagy, reducing the number of mitochondria, and inhibiting the mRNA expression of polarization markers in M2 macrophages.
