Objective:To construct a hierarchical training course system for neonatal nurses based on core competencies, to provide a reference for meeting the training needs of neonatal nurses under the new situation.Methods:Through literature review, questionnaire survey on training needs, and focus group interviews, a preliminary hierarchical training curriculum system for neonatal nurses was developed. Two rounds of Delphi correspondence were conducted with 19 domestic experts to finalize the system.Results:The effective questionnaire recovery rates of the two rounds of expert consultation were 95.00% and 100.00%, and the expert authority coefficient was 0.916, the Kendall harmony coefficient of the first round of expert opinions was 0.351 ( P<0.001), and the Kendall harmony coefficient of the second round of expert opinions was 0.463 ( P<0.001). The hierarchical training course structure and course training content are formed, including N0: 3 first-level items, 9 second-level items, 80 third-level items, N1: 3 first-level items, 9 second-level items, 91 third-level items, N2: 3 first-level items, 9 second-level items, 86 third-level items, N3: 3 first-level items, 10 second-level items, 81 third-level items, N4: 3 first-level items, 10 second-level items, 76 third-level items. Conclusions:The hierarchical training course system for neonatal nurses based on the core competence of nurses is scientific and practical, which can provide a reference for the hierarchical training of neonatal nurses.

Objective:To investigate the relationship between thoracic aortic calcification (TAC) and autonomic nervous system (ANS) function in patients receiving continuous ambulatory peritoneal dialysis (CAPD).Methods:It was a cross-sectional study. The CAPD patients with dialysis duration >6 months between January and December 2022 were retrospectively enrolled. The baseline clinical data, heart rate variability (HRV) data such as standard deviation of all normal to normal intervals (SDNN), root mean square of successive differences between adjacent normal-to-normal intervals (RMSSD), high frequency (HF), very low frequency (VLF), low frequency (LF), LF/HF, acceleration capacity (AC) and deceleration capacity (DC), and skin sympathetic nerve activity (SKNA) were collected. TAC was defined as TAC score (TACS) >100 AU. The patients were divided into TACS >100 AU group and TACS≤100 AU group based on whether the thoracic aorta was calcified. The differences of those data between the two groups were compared. Logistic regression model was used to analyze the related factors of TAC. Spearman correlation analysis method was used to analyze the correlation between peripheral blood neuropeptide Y, ANS parameters, average amplitude SKNA (aSKNA) and TACS.　Cox regression model was used to analyze the risk factors of all-cause mortality in patients with CAPD.Results:The study included 106 CAPD patients with 50 males (47.2%), age of (46.04±11.10) years and dialysis duration of (41.55±30.52) months. TACS>100 AU group exhibited significantly lower heart rate ( t=2.015, P=0.046), DC ( t=2.131, P=0.035), LF/HF ( Z=3.332, P<0.001) and ln(LF/HF) ( t=3.326, P=0.001), and higher AC ( t=-2.392, P=0.019) than TACS≤100 AU group. Multivariate logistic regression analysis results showed that after adjusting for age and eosinophil count, lnVLF ( OR=0.66, 95% CI 0.45-0.98, P=0.038), lnLF ( OR=0.69, 95% CI 0.49-0.97, P=0.032), DC ( OR=0.79, 95% CI 0.64-0.99, P=0.039) and AC ( OR=1.32, 95% CI 1.04-1.68, P=0.021) were independently correlated with the risk of TAC. Spearman correlation analysis showed that neuropeptide Y level in peripheral blood was correlated with aSKNA ( r=0.23, P=0.017), lnSDNN ( r=-0.20, P=0.036) and TACS ( r=0.19, P=0.048). During the follow-up period of (25.8±4.2) months, 5 patients (4.72%) died, including 1 patient in the TACS≤100 AU group and 4 patients in the TACS>100 AU group. Compared with the survival group, the death group had higher TACS ( Z=-2.262, P=0.024) and lower LF/HF ( Z=-2.750, P=0.006). Cox regression analysis results showed that increased ln(LF/HF) was an independent influencing factor for all-cause mortality in CAPD patients ( HR=0.22, 95% CI 0.05-0.83, P=0.026). Conclusions:HRV parameters (lnVLF, lnLF, AC and DC) of CAPD patients are independently associated with TAC. The dysfunction of ANS in CAPD patients (especially the decreased vagus nerve activity) may promote TAC.

To summarize the rescue and care of a case of breath-holding attack caused by congenital contractures of limbs and face,hypotonia,and developmental delay(CLIFAHDD)syndrome.Key points of nursing:early identification and intervention of breath-holding attack in CLIFAHDD syndrome,and implementation of rapid reactive rescue;implementing individualized developmental care measures to avoid stimuli that induce breath-holding attack;paying attention to the assessment of oral feeding ability,strengthening the exercise of oral feeding ability and nutrition management;strengthening perioperative diversified airway management to prevent postoperative complications;the monitoring of early neurological and motor system development,and early start of rehabilitation care;doing a good job in health education for caregivers to help them master the first aid treatment and growth and development assessment methods in the event of a breath-holding attack.After 53 days of hospitalization,the patient was discharged.After being discharged from the hospital for more than 1 month,the patient had breath-holding attack 2～4 times a day.After being discharged from the hospital for more than 2 months,the patient had no breath-holding attack,and only had occasional convulsive seizures during sleep,which could be relieved spontaneously.

Objective: To investigate the surgical options for splenic lymph node dissection in patients with advanced gastric cancer undergoing radical total gastrectomy, and to evaluate the sentinel effect of No. 4s lymph node on splenic lymph node metastasis. Methods: A prospective, single-center, randomized and controlled study was carried out (Trial registration, No.NCT02980861). Enrollment criteria: (1) >18 years old and <65 years old; (2) gastric adenocarcinoma locating in the proximal or corpus; (3) preoperative clinical staging as cT2-4aN0-3M0; (4) D2 radical total gastrectomy feasible judged before operation; (5) physical ability score 0 to 1; (6) I to III of ASA classification. Pregnant or lactating women, patients with severe mental illness or previous history of upper abdominal surgery, those suffered from other malignant tumors in the past 5 years, or heart and lung system diseases judged to affect surgery before operation, those receiving preoperative chemotherapy, radiotherapy or targeted therapies, and distant metastases being found during surgery were excluded. According to above criteria, 222 patients at The First Medical Center of Chinese PLA General Hospital from December 2016 to December 2017 were enrolled prospectively and were randomly divided into the laparoscopic splenic hilar lymph node dissection group (laparoscopic group, n=114) and the open splenic hilar lymph node dissection group (open group, n=108). The result of rapid frozen immunohistochemistry of harvested No.4s lymph nodes was used to evaluate the sensitivity and specificity of sentinel effect on splenic hilar lymph node metastasis. The surgical parameters, postoperative recovery parameters, and complication rates were compared between the two groups. Results: There were 80 males and 34 females in the lapascopic group with a mean age of (56.1±10.2) years, and 69 males and 39 females in the open group with a mean age of (58.4±10.9) years. There were no significant differences in baseline data between the two groups (all P>0.05). Total blood loss was less in the laparoscopic group [(96.3±82.4) ml vs. (116.6±101.9) ml, t=1.124, P<0.001], and the amount of bleeding from the splenic hilar lymph nodes dissected was also less than that in the open group [(25.3±17.8) ml vs. (59.5±36.4) ml, t=1.172, P<0.001]. However, the operation time, the time of splenic hilar lymph node, the number of lymph node dissected and number of splenic hilar lymph node dissected were not significantly different between the two groups (all P>0.05). As compared to the open group, the laparoscopic group had shorter time to the first flatus [(1.3±1.2) days vs. (1.6±1.5) days, t=1.665, P=0.021], shorter time to fluid diet [(4.6±1.4) days vs. (4.9 ± 1.6) days, t=1.436, P=0.007], shorter time to remove nasogastric tube [(3.9±2.6) days vs. (4.3±2.4) days, t=0.687, P<0.001] and shorter hospital stay [(10.3±6.6) days vs. (12.1±7.2) days, t=0.697, P<0.001]. Complication rate was 14.0% (16/114) and _12.0% (₁3/108) in the laparoscopic group and the open group, respectively, without significant difference (χ²=6.723, P=0.331). The sensitivity of the No. 4s lymph node for the prediction of splenic hilar lymph node metastasis reached 89.5%, and the specificity reached 99.6%. Conclusions Laparoscopic technique is safe and feasible in the treatment of splenic hilar lymph node dissection in advanced gastric cancer. The No.4s lymph node examination has good sentinel effect on predicting the metastasis of splenic hilar lymph nodes.

Objective:The storage of medical data has been digitized in China, but a unified and structured model has not yet been established. The standardized collection, analysis and sorting of tumor clinical data is the foundation of improving the standard of tumor diagnosis and treatment. Therefore, establishing a database platform of gastric cancer (GC) is an urgent need to integrate data resources and improve the level of diagnosis and treatment. The population economics indexes of GC patients in the last 20 years are analyzed in a single-center GC database. The medical records were structured by natural language processing technology. Authors aim to investigate the clinical pathological characteristics, staging and survival of the GC patients with gastrectomy.Method:A retrospective cohort study was carried out. Clinicopatological data of patients receiving surgical treatment from 2000 to 2019 were retrospectively collected. According to the gastric cancer TNM staging guidelines from the Union for International Cancer Control and the American Joint Committee on Cancer (UICC/AJCC) 8th edition, the structured gastric cancer clinicopathological data were re-evaluated and interpreted. The Kaplan-Meier method and the log-rank test were used to compare survival rate among different groups of patients with complete follow-up data of 2010-2016.Results:Clinicopathological data of 13 492 GC patients were enrolled. The ratio of men to women in the whole group was 3.25:1.00, including 10 320 men with average onset age of 59.68 years, which was basically stable in recent 20 years, and 3172 women with average onset age of 55.93 years, which presented a trend of average increasement of 0.17 year per year. The average hospitalization duration for GC patients showed a decreasing trend year by year, which was 13.87 days in 2019. Average hospitalization cost for GC patients was increasing year by year, with a peak of 83 600 CNY in 2017 and 75 400 CNY in 2019. By natural language identification and exclusion criteria screening, a total of 7218 GC patients obtained structured clinicopathological information. Analysis on clinicopathological characteristics of 3626 GC patients in the last 5 years showed that the average diameter of tumor was (4.44±2.61) cm; the average number of harvested lymph node was 24.30±13.29; the proportion of surgical methods were as following: open surgery in 1398 cases (38.55%), laparoscopic surgery in 1856 cases (51.19%) and robotic surgery in 372 cases (10.26%). The postoperative pathological stage was as following: IA in 658 cases (18.15%), IB in 318 cases (8.77%), IIA in 559 cases (15.42%), IIB in 543 (14.98%), III A in 632 (17.43%), III B in 612 cases (16.88%), III C in 276 cases (7.61%), and IV in 28 cases (0.77%). Complete follow-up data of 3431 patients from 2010 to 2016 were presented. The 1-, 3- and 5-year survival rates were 82%, 69% and 60%, respectively for the whole group. The 1-, 3- and 5-year survival rates for patients undergoing laparoscopic surgery were 83%, 70% and 64%, respectively, and for those undergoing open surgery were 81%, 67% and 56%, respectively, and the difference between the two groups was not statistically significant ( P=0.109). The 5-year survival rate of GC patients with different AJCC stages was as following: 88% in IA, 77% in IB, 70% in II A, 62% in II B, 44% in III A, 32% in III B, 22% in III C, and 17% in IV. Conclusion:This study provides basic data for the establishment of comprehensive diagnosis and treatment model of multicenter, shedding light on the improvement of comprehensive treatment of GC in China.

Objective: To compare the short-term and long-term outcome between robotic gastrectomy and laparoscopic gastrectomy. Methods: The clinical data of 517 patients who had received robotic gastectomy and laparoscopic gastrectomy between December 2011 and December 2013 at Department of General Surgery, Chinese People′s Liberation Army General Hospital was collected. After propensity score matching, 70 patients in robotic gastectomy and 70 patients in laparoscopic gastectomy were identified. Perioperative outcome and overall survival were compared between the two groups using t test, χ² test, Kaplan-Meier curve and Log-rank test, respectively. Prognosis factors were analyzed by Cox′s proportional hazards regression. Results: There were comparable baseline characteristics between patients in robotic group (RG) and those in laparoscopic group (LG). The conversion rate for RG and LG were 5.7% and 4.3% respectively (P=1.000). Compared with LG, RG had similar lymph node retrieval (25.5±7.2 vs. 24.5±8.3, t=0.770, P=0.443) and less blood loss ((147.0±96.8) ml vs. (188.0±111.2) ml, t=-2.326, P=0.021). There were also similar complications (χ²=0.233, P=0.629) and severity of complications (W=70.500, P=0.053). Although there tended to be early mobility, early flatus and less hospital stay for patients in RG group, the difference between RG and LG was not statistically significant. The 3-year survival rate was 72.9% and 60.0% for patients in RG and patients in LG (P=0.578). Multivariable analysis revealed gender (HR=2.529, 95% CI: 1.042 to 6.140, P=0.040), neoadjuvant chemotherapy (HR=0.272, 95% CI: 0.104 to 0.710, P=0.008) and vascular invasion (HR=2.135, 95% CI: 1.027 to 4.438, P=0.042) were independent prognostic factors. Conclusion Compared with laparoscopic gastrectomy, robotic gastectomy could achieve similar short-term and long-term outcomes.

OBJECTIVETo analyze relationships between the tumor deposits (TD) and clinicopathologic features of gastric cancer and investigate the value of TD in staging and prognosis in gastric cancer patients.

METHODSRetrospective cohort study was conducted to evaluate the clinicopathologic data of 388 gastric cancer patients who underwent surgical procedures in Chinese PLA General Hospital between November 2011 and December 2012. Relationships between TD and clinicopathologic features were analyzed by χor Fisher exact tests. Survival curves were also generated by Kaplan-Meier method. The univariate and multivariate analysis were performed with Log-rank and COX proportional hazard model to examine the association between prognosis and TD.

RESULTSTD were observed in 67 (17.3%) of 388 gastric cancer patients, including 48 male patients (48/289, 16.6%) and 19 female patients (19/99, 19.2%). There were 40 patients (40/198, 20.2%) whose age was above 64 years old. TNM staging of positive TD patients was as follows: for pathology, there were 5 patients (5/64, 7.8%) in stage II(b, 6 patients (6/58, 10.3%) in stage III(a, 14 patients (14/75, 18.7%) in stage III(b, 30 patients (30/135, 22.2%) in stage III(c, 12 patients (12/39, 30.8%) in stage IIII( and no one in stage I(b or II(a; for T-staging, there were 2 patients (2/18, 11.1%) in stage T2, 2 patients (2/27, 7.4%) in stage T3, 36 patients (36/259, 13.9%) in stage T4a and 27 patients (27/84, 32.1%) in stage T4b; for N-stage, there were 5 patients (5/72, 6.9%) in stage N0, 6 patients (6/72, 8.3%) in stage N1, 19 patients (19/82, 23.2%) in stage N2, 27 patients (27/100, 27.0%) in stage N3a and 10 patients(10/62, 16.1%) in stage N3b; for M-stage, there were 12 patients (12/40, 30.0%) in distal metastases; for vascular invasion, there were 29 patients (29/129, 22.5%). Among positive TD patients, the number of TD >3 was found in 38 of 67 cases(56.7%). TD was associated with pTNM-stage (χ=16.898, P=0.010), T-stage (χ=17.382, P=0.001), N-stage (χ=18.080, P=0.001), M-stage (χ=5.060, P=0.036) and vascular invasion(χ=3.675, P=0.039). The median survival time of positive TD patients was significantly shorter as compared to negative TD patients (22 months vs. 32 months, χ=23.391, P=0.012). Among positive TD patients, the median survival time of patients with TD number >3 was significantly shorter as compared to those with TD number <3 (17 months vs. 25 months, χ=5.157, P=0.023). Multivariate survival analysis showed that TD number >3 was the independent risk factor of prognosis (RR=2.350, 95%CI:1.345 to 4.106, P=0.003).

CONCLUSIONSTD state is closely associated with the staging of gastric cancer and TD number >3 indicates a poor prognosis.
