Objective:To establish the evaluation criteria for the quality of nursing care in orthopaedic trauma specialties, and to provide a basis for scientific evaluation of the quality of nursing care in orthopaedic trauma specialties.Methods:From February to October 2023, John Hopkinson evidence-based method was used to synthesize the evidence, clinical investigation and semi-structured interview were used to draw up the "quality standard of nursing care in orthopaedic trauma specialty", and two rounds of Delphi method of expert inquiry were used to screen, demonstrate and calibrate the evaluation standard of nursing quality in orthopaedic trauma specialty.Results:The questionnaire recovery rate of 2 rounds of expert consultation was 100.00%, the coefficient of familiarity and authority of 2 rounds of expert consultation were 0.92 and 0.93. Through 2 rounds of expert letter consultation, the quality evaluation criteria of orthopaedic trauma specialist care were established, including 3 first-level indicators (structural quality, process quality and outcome quality), 22 second-level indicators and 85 third-level indicators.Conclusions:The process of constructing the evaluation standard of nursing quality in orthopaedic trauma specialty is scientific and reliable, which can provide standard guidance for clinical practice and is conducive to the development of specialized nursing.

Objective:To investigate the change of D-Dimer (D-D), cardiac troponin I (cTnI) and vasoactive-inotropic score (VIS) after Stanford type A aortic dissection (TAAD) and thier predictive effect on death outcome.Methods:120 patients with TAAD who were treated in the Affiliated Hospital of Jining Medical College from January 2019 to January 2022 were retrospectively selected and divided into death group ( n=17) and survival group ( n=103) according to the 28-day survival after operation. The difference of clinical data between the two groups was compared, and the influencing factors of postoperative death in TAAD patients were analyzed by logistic regression method. Results:The age, deep hypothermic circulatory arrest time, D-D and cTnI of the patients in the death group were (60.50±5.42)years old, (30.40±9.92)min, (15.65±5.52)g/L and (3.32±0.82)mg/L, respectively, which were significantly higher than those in the survival group (all P<0.05). The VIS score and change of VIS score in the death group at 24 hours after operation were (9.66±1.10)points and (4.50±0.91)points respectively, which were significantly higher than those in the survival group (all P<0.05). Logistic regression analysis showed that age, D-D, cTnI and change of VIS score were the influencing factors of death after TAAD (all P<0.05). The area under the receiver operating characteristic (ROC) curve predicted by the D-D, cTnI and change of VIS score for death in TAAD patients was 0.718, 0.691 and 0.789 respectively (all P<0.05). Conclusions:Postoperative death of TAAD patients is affected by their age, D-D, cTnI and change of VIS score. The D-D, cTnI and change of VIS score have certain application value in predicting postoperative death of patients.

Objective:To compare the difference in measurement results and nursing time between wireless body temperature pulse measuring system and the traditional mercury thermometer combined with hand diagnostic method for measuring body temperature and pulse, to provide a reference for clinical selection of accurate and efficient vital sign measuring tools.Methods:A total of 74 patients hospitalized in the Orthopedics Department of the First Medical Center of the PLA General Hospital from March to August 2022 were selected using a randouized coutrolled study. The body temperature and pulse data of every patients were collected by mercury thermometer + manual diagnosis and wireless body temperature pulse measuring system at the same time, and the measurement results and nursing time of the two methods were compared.Results:The temperature and pulse measured by the wireless body temperature pulse measuring system were (36.31 ± 0.52) ℃ and (78.27 ± 14.06) times/min, which were no significant different than (36.34 ± 0.51) ℃ and (78.57 ± 13.79) times/min by the mercury thermometer + manual diagnosis ( t = -1.54, 1.88, both P>0.05), and the two groups of data were significantly correlated, ( r = 0.940 and 0.995, both P<0.01). The daily nursing work time of the wireless body temperature pulse measuring system was (67.29 ± 5.15) min, which was significantly lower than (131.57 ± 6.58) min by the mercury thermometer + manual diagnosis ( t = 20.35, P<0.01). Conclusions:The wireless body temperature pulse measurement system is accurate in data collection, easy to operate, safe to use, less time-consuming in nursing work and worthy of clinical promotion.

BACKGROUND: Research on the relationship between residential altitude and hypertension incidence has been inconclusive. Evidence at low altitudes (i.e., <1,500 m) is scarce, let alone in older adults, a population segment with the highest hypertension prevalence. Thus, the objective of this study is to determine whether hypertension risk may be affected by altitude in older adults living at low altitudes. METHODS: This prospective cohort study collected data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We selected 6,548 older adults (≥65 years) without hypertension at baseline (2008) and assessed events by the follow-up surveys done in 2011, 2014, and 2018 waves. The mean altitude of 613 residential units (county or district) in which the participants resided was extracted from the Digital Elevation Model (DEM) of the National Aeronautics and Space Administration (NASA) and was accurate to within 30 m. The Cox regression model with penalized splines examined the linear or nonlinear link between altitude and hypertension. A random-effects Cox regression model was used to explore the linear association between altitude and hypertension. RESULTS: The overall rate of incident hypertension was 8.6 per 100-person years. The median altitude was 130.0 m (interquartile range [IQR] = 315.5 m). We observed that the exposure-response association between altitude and hypertension incidence was not linear. The shape of the exposure-response curve showed that three change points existed. Hypertension risk increased from the lowest to the first change point (247.1 m) and slightly fluctuated until the last change point (633.9 m). The risk decreased above the last change point. According to the categories stratified by the change points, altitude was only significantly associated with hypertension risk (hazard ratio [HR] = 1.003; 95% confidence interval [CI] = 1.002-1.005) under the first change point (247.1 m) after adjusting for related covariates. CONCLUSION Our study found that the association between altitude and hypertension risk might not be linear. We hope the further study can be conducted to confirm the generality of our findings.

Objective:To explore the effect of diet safety management based on swallowing function classification in perioperative period of elderly patients with hip fractures, so as to provide basis for improving perioperative food safety and shortening hospitalization time of patients with hip fracture.Methods:A total of 68 elderly patients with hip fractures in the First Medical Center of PLA General Hospital from December 2020 to August 2021 were selected and divided into experimental group and control group according to even and odd-number of admission number, each group contained 34 patients. The control group was given routine diet nursing and food safety education. The experimental group was given graded diet safety management according to the swallowing function evaluation results. The incidence of aspiration and length of hospital stay were compared between the two groups.Results:The incidence of chocking during hospitalization was 5.1% (78/1 517) in the control group and 1.2% (17/1 402) in the experimental group, and the difference was statistically significant ( χ2=35.73, P<0.01). The incidence of choking in the control group was 0.7% (11/1 517), and 0.4% (5/1 402) in the experimental group, and the difference was not statistically significant ( χ2=1.82, P>0.05). There was no significant difference in hospitalization time between the two groups, 10 (8,12) in the control group and 9 (8,11) in the experimental group ( Z=-1.33, P>0.05). Conclusions:The implementation of diet safety management based on swallowing function classification in elderly patients with hip fractures can reduce the incidence of coughing. Evaluation of swallowing function should be included in the evaluation of hip fractures in the elderly.

Objective:To compare the pathological results and complications of limited and extended pelvic lymph node dissection among high-risk prostate cancer patients, and to explore the risk factors that affect the rate of lymph node metastasis in high-risk prostate cancer patients.Methods:The data of 800 high-risk prostate cancer patients who underwent radical prostatectomy and pelvic lymph node dissection from January 2016 to December 2020 in three affiliated hospital of Sun Yat-sen University were analyzed retrospectively. According to the scope of pelvic lymph node dissection, they were divided into limited pelvic lymph node dissection (LPLND) group and extended pelvic lymph node dissection (EPLND) group. There were 172 patients underwent LPLND, and 628 patients underwent EPLND.The age of the patients in the LPLND group was 67 (62, 72) years old, diagnosed PSA 20.7 (10.9, 54.8) ng/ml. The biopsy Gleason score 6 in 22 cases, 7 in 59 cases, 8 in 56 cases and 9-10 in 35 cases.The clinical T stage: T 1 in 29 cases, T 2 in 102 cases, T 3 in 37 cases, T 4 in 4 cases; N 0 in 160 cases and N 1 in 12 cases. 50 patients received neoadjuvant hormonal therapy. The age of patients in the EPLND group was 67 (63, 72) years old, diagnosed PSA was 23.9 (14.0, 46.8) ng/ml. Biopsy Gleason Score 6 in 51 cases, 7 in 194 cases, 8 in 218 cases and 9-10 in 165 cases. Clinical T stage: T 1 in 114 cases, T 2 in 341 cases, T 3 in 144 cases, T 4 in 29 cases; N 0 in 526 cases and N 1 in 102 cases.158 patients received neoadjuvant hormonal therapy. There were no significant differences in the age, PSA, puncture Gleason score, clinical T stage, and whether or not to receive neoadjuvant hormonal therapy between the two groups of patients ( P>0.05). The difference in clinical N staging was statistically significant ( P=0.002). The number of postoperative lymph nodes, positive pelvic lymph nodes and postoperative complications and other related clinical and pathological data of the two groups were analyzed. Multivariate logistic regression was used to analyze the risk factors of patients with positive lymph nodes. Results:The median number of lymph nodes harvested [13(8, 19)vs. 6(4, 13), P<0.001] and the rate of positive lymph node cases[31.2%(196/628) vs. 10.5%(18/172), P<0.001] in the EPLND group was significantly higher than those in the LPLND group. Preoperative PSA, clinical N staging, Gleason score, and way of lymph node dissection were independent risk factors for postoperative positive pelvic lymph node in high-risk prostate cancer patients. Compared with the LPLND group, the ELPND group had a higher postoperative complication rate [19.9%(125/628) vs. 11.0%(11/172), P=0.007]. Conclusions:Compared with the LPLND, EPLND in high-risk prostate cancer patients can harvest more lymph nodes and increase the detection rate of positive lymph nodes. The complications of EPLND were higher than those of LPLND. Preoperative PSA, clinical N stage, Gleason score, and the way of lymph node dissection are independent risk factors for positive pelvic lymph node dissection.

OBJECTIVE: To explore the expression of perforin and granzyme-B in peripheral blood lymphocyte (PBL) in patients with prostate cancer (PCa) and the clinical significance. METHODS: The expressions of perforin and granzyme-B in PBL were detected by fluorescence quantitative reverse transcription polymerase chain reaction. The results of perforin and granzyme-B expression were compared among patients with PCa (n=60), patients with BPH (benign prostatic hyperplasia, n=40) and healthy controls (n=20). RESULTS: Th e expressions of perforin and granzyme-B in patients with PCa were significantly lower than that in patients with BPH or that in the healthy controls (P<0.05), respectively. Furthermore, in PCa patients with low pathological grade, the expressions of perforin and granzyme-B in PBL was statistically higher than that in patients with high pathological grade (P<0.05). The expressions of perforin and granzyme-B in PCa patients at high clinical stage was statistically lower than that in PCa patients at low clinical stage (P<0.05). CONCLUSION The results of this study suggest that development and progression of PCa might be associated with poor immune status of patients.

Hannum and colleagues performed DNA methylation sequencing to examine the relationship between DNA methylome and aging rate. Notably, they succeeded in building a quantitative and reproducible model based on the epigenetic bio-markers to predict aging rate with high accuracy. This progress enlightens us in many aspects particularly in applying this novel set of bio-markers on studying the mechanism of aging rate using adult tissue-specific stem cells, building up a potential quantitative model to explore the mechanism for other epigenetic factors like non-coding RNA, and understanding the principle and mechanism of 3D chromatin structure in epigenetic modulation.

Recent studies have been raising doubts on the safety of induced pluripotent stem cells (iPSCs) and proposing that the process of reprogramming brought about copy number variations (CNVs) in iPSCs. However, a recent paper published in Nature provided evidence showing that most CNVs were pre-existed as somatic mosaicism but not resulted from the reprogramming. This new finding would profoundly reshape some previous thoughts and endorse the confidence of iPSCs in both research and therapy.
