Objective:To explore the research status of artificial intelligence in nursing in China, so as to provide reference for conducting research domestically.Methods:The relevant literature collected from January 1, 2003 to May 1, 2023 was searched on China National Knowledge Infrastructure, WanFang Data, and VIP. CiteSpace and VOS viewer were used to visually analyze the research status, hotspots, and frontiers of artificial intelligence in nursing in China from the aspects of annual publication volume, region, institution, author, high-frequency keywords, and emerging words.Results:A total of 494 articles were included. In terms of publication volume, domestic research showed an overall upward trend, with publishing institutions mostly concentrated in economically developed and medically advanced regions. The authors of the articles often collaborated with research groups, with a co-authorship rate of 81.17% (401/494), but there was relatively little collaboration between groups. Research hotspots were focused on the application of artificial intelligence in geriatric nursing, rehabilitation nursing, Operating Rooms, and drug formulation, with a majority of research related to robots.Conclusions:The research enthusiasm in related fields in China is currently on the rise. Research on artificial intelligence in nursing management, nursing education, and psychological nursing can be strengthened, and the application of artificial intelligence can be enriched. At the same time, research institutions and personnel should strengthen mutual cooperation, and relevant national departments should improve laws and regulations to promote the vigorous development of this research field.

Objective:To analyze the current research status of ideological and political education content in domestic nursing courses and facilitate nursing education reform.Methods:Using purposeful sampling, 25 exemplary cases of ideological and political education in nursing courses from Xinhua Net were selected. NVivo 12 software was employed for content analysis, summarizing the ideological and political elements, carriers of these elements, and types of integration methods in nursing courses.Results:Nursing educators have thoroughly explored ideological and political elements, with the most attention given to professional ethics, though less focus was placed on personality development. A variety of carriers for ideological and political elements were utilized, with practical experience being the most common, but there was a lack of integration with policy and regulations. Various integration methods were applied, with interactive methods being the most frequently used, while practical approaches were less common.Conclusions:Future nursing education should emphasize fostering students' sense of national identity and focus more on personality development. It is important to promote a more balanced use of carriers for ideological and political elements, paying particular attention to policy-related content. The use of information technology in teaching should also be explored to flexibly apply various teaching methods, achieving the subtle integration of ideological and political education within nursing curricula.

Overactive bladder (OAB) is the most bothersome symptom in lower urinary tract symptoms (LUTS). Current pharmacologic treatment aims to inhibit detrusor contraction; however, shows unsatisfied efficacy and high discontinuation rate. LIM kinases (LIMKs) promote smooth muscle contraction in the prostate; however, their function in the bladder smooth muscle remains unclear. Here, we studied effects of the LIMK inhibitors on bladder smooth muscle contraction and proliferation both

OBJECTIVE: To investigate the effect of the chemoprotectant tempol on the anti-tumor activity of cisplatin (DDP). METHODS: The cellular toxicity of tempol in human colon cancer SW480 cells and mouse colon cancer CT26 cells were evaluated using MTT and cell counting kit-8 assays. CalcuSyn software analysis was used to determine the interaction between tempol and DDP in inhibition of the cell viability. A subcutaneous homograft mouse model of colon cancer was established. The mice were randomly divided into control group, tempol group, cisplatin group and tempol + DDP treatment group with intraperitoneal injections of the indicated agents. The tumor size, body weight and lifespan of the mice were measured, and HE staining was used to analyze the cytotoxic effect of the agents on the kidney and liver. Immunohistochemistry and Western blotting were performed to detect the expression of Bax and Bcl2 in the tumor tissue, and TUNEL staining was used to analyze the tumor cell apoptosis. The level of reactive oxygen species (ROS) in the tumor tissue was determined using flow cytometry. RESULTS: Tempol showed inhibitory effects on the viability of SW480 and CT26 cells. CalcuSyn software analysis showed that tempol had a synergistic anti-tumor effect with DDP (CI < 1). In the homograft mouse model, tempol treatment alone did not produce obvious anti-tumor effect. HE staining showed that the combined use of tempol and DDP alleviated DDP-induced fibrogenesis in the kidneys, but tempol also reduced the anti-tumor activity of DDP. Compared with the mice treated with DDP alone, the mice treated with both tempol and DDP had a significantly larger tumor size ( < 0.01) and a shorter lifespan ( < 0.05). Tempol significantly reversed DDP-induced expression of Bax and Bcl2 in the tumor tissue and tumor cell apoptosis ( < 0.001), and obviously reduced the elevation of ROS level in the tumor tissue induced by DDP treatment ( < 0.05). CONCLUSIONS Tempol can attenuate the anti-tumor effect of DDP while reducing the side effects of DDP. Caution must be taken and the risks and benefits should be carefully weighed when considering the use of tempol as an anti-oxidant to reduce the toxicities of DDP.

Objective: To investigate the application value of caesarean section scar or bikini line incisional approach in laparoscopic sleeve gastrectomy. Methods: The retrospective cohort study was conducted. The clinical data of 162 patients with obesity and metabolic diseases who were admitted to the First Affiliated Hospital of Jinan University between March 2018 and April 2019 were collected. There were 51 males and 111 females, aged (35±8)years, with a range from 12 to 47 years. Of 162 patients, 72 undergoing laparoscopic sleeve gastrectomy via caesarean section scar or bikini line incisional approach and 90 undergoing laparoscopic sleeve gastrectomy via traditional incisional approach were respectively allocated into concealed incision group and traditional incision group. Observation indicators: (1) surgical situations; (2) intraoperative situations; (3) postoperative situations; (4) follow-up. Follow-up using outpatient examination, telephone interview, and WeChat was performed to detect the postoperative complications at 1, 3, 6 months and 1, 2, 5 years postoperatively up to May 2019. Measurement data with normal distribution were represented as Mean±SD, and the t test was used for comparison between groups. Count data were represented as absolute numbers, and were analyzed by the chi-square test or fisher exact probability. Ordinal data were analyzed by the Wilcoxon rank sum test. Results: (1) Surgical situations: patients in the concealed incision group and traditional incision group underwent successfully laparoscopic sleeve gastrectomy, without conversion to open surgery, reoperation, or perioperative death. (2) Intraoperative situations: the operation time and volume of intraoperative blood loss of the concealed incision group were (102±17)minutes and (11±4)mL, respectively, versus (105±19)minutes and (11±4)mL of the traditional incision group (t=-1.232, -0.676, P>0.05). There were 6 cases and 21 cases with additional surgical ports during operation in the concealed incision group and traditional incision group, respectively, with a significant difference between the two groups (χ²=6.280, P<0.05). (3) Postoperative situations: in the concealed incision group, 56 patients were very satisfied with scar appearance and 16 patients were satisfied with scar appearance. In the traditional incision group, 42 patients were very satisfied with scar appearance and 48 patients were satisfied with scar appearance. There was a significant difference in the overall satisfaction with the incision scar between the two groups (Z=-4.012, P<0.05). Duration of postoperative hospital stay and total hospital expenses of the concealed incision group were (4.9±0.9)days and (64 408±5 123)yuan, versus (5.2±1.5)days and (64 953±3 477)yuan of the traditional incision group (t=-1.788, -0.804, P>0.05). There were 19 and 14 patients with gastroesophageal reflux in the concealed incision group and traditional incision group, respectively, with no significant difference between the two groups (χ²=2.894, P>0.05). There was no postoperative complication such as infection, hemorrhage or anastomotic leakage in either group. (4) Follow-up: 32 of 162 patients were lost to follow-up, including 10 in the concealed incision group and 22 in the traditional incision group; other 130 patients were followed up for 1-14 months, with a median follow-up time of 7 months. During the follow-up, 1 patient in the traditional incision group was hospitalized again at 3 months after surgery due to upper gastrointestinal bleeding, and was cured after symptomatic supportive treatment. One patient in the concealed incision group was admitted to the local hospital for functional obstruction at 1 month after surgery and was discharged after symptomatic treatment. Other patients had no readmission due to postoperative complications. Conclusion Laparoscopic sleeve gastrectomy via caesarean section scar or bikini line incision is safe and feasible, with good cosmetic effects.

Objective To evaluate the impacts of DRGs payment reform on patients, medical insurance fund and hospitals, then to steadily promote the payment reform. Methods The reimbursement data of inpatients covered by NCMS yet beyond the single-disease payment were collected from two DRGs pilot hospitals from January 2016 to June 2018. Such means as descriptive statistics, t test and method of interrupted time series analysis were used to compare the changes found in the average out-of-pocket payment, actual reimbursement rate, average per-hospitalization compensation, average length of stay, and average hospitalization expense before and after the DRGs payment reform. Results After the reform, the average out-of-pocket payment and average length of stay began to fall slightly instead of the increasing trend (β3 were -72.79,-0.11, respectively, and P<0.01), the upward trend of average hospitalization expense slowed down ( β3 was -113. 55, and P<0.01), actual reimbursement rate and the average per-hospitalization compensation stayed the original growth trend (β3 were 0.10,-31.15, respectively, and P values were 0.08, 0.09, respectively). Conclusions DRGs encourages the hospitals to curb the average hospitalization expenses, with the growth trend kept at a slower pace. The payment reform does not increase the financial burden of patients, and tends to ease such pressure on funds, but the long-term effect remains to be seen.

Liver cancer is a common type of malignant tumor in digestive system. At present, computed tomography (CT) plays an important role in the diagnosis and treatment of liver cancer. Segmentation of tumor lesions based on CT is thus critical in clinical diagnosis and treatment. Due to the limitations of manual segmentation, such as inefficiency and subjectivity, the automatic and accurate segmentation based on advanced computational techniques is becoming more and more popular. In this review, we summarize the research progress of automatic segmentation of liver cancer lesions based on CT scans. By comparing and analyzing the results of experiments, this review evaluate various methods objectively, so that researchers in related fields can better understand the current research progress of liver cancer segmentation based on CT scans.

Objective To investigate the safety and efficacy of laparoscopic ureteroureterostomy with intraoperative retrograde ureteroscopy-assisted technique in the treatment of ureteral strictures secondary to Holmium laser lithotripsy.Methods The clinical data of 26 cases of ureteral strictures secondary to Holmium laser lithotripsy performed by laparoscopic ureteroureterostomy from December 2013 to January 2016 in our hospital were analyzed retrospectively.The patients included 15 men and 11 women,with an average age of 39.5 years (range 24-71 years).The ureteral strictures secondary to holmium laser lithotripsy were found on average follow-up of 5.2 months (range 1-22 months).There were 12 cases of mild hydronephrosis before surgery,moderate hydronephrosis in 11 cases,severe hydronephrosis in 3 cases.Preoperative serum creatinine was 102.0 μ mol/L on average (range 53.3-201.4 μmol/L),and ureteral stenosis length was 15.0 mm on average (range 8.0-26.0 mm).The upper ureteral strictures in 6 cases,the middle strictures in 13 cases,and the lower strictures in 7 cases.Results All the operations were completed successfully without conversion to open and no intraoperative death.The average operation time was 121.4 min(range 90-155 min);the estimated blood loss was 92.3 ml (range 30-200 ml);the mean recovery time of gastrointestinal function after operation was 1.4 d(range 0.5-2.5 d);the mean hospital stay was 6.2 d(range 4-9 d)with indwelling double J;the Foley catheter was removed 14.5 d(range 12-16 d)postoperatively;the mean time of double J withdrawal was 76.3 d(range 61-86 d).Postoperative fever occurred in two patients and were successfully treated by re-indwelling catheter and antibiotic administration.Urine leakage occurred in 1 patient postoperatively and was successfully treated by conservative management 5 days later.After a period of 11 to 22 months of follow-up,no patient had ureteric re-stenosis.Conclusions Laparoscopic ureteroureterostomy with intraoperative retrograde ureteroscopyassisted technique could accurately locate and cure the ureteral strictures.It might be safe and effective with short operation time,less injury and quick recovery.

Objective To analyze the operation of the diagnosis-related groups ( DRGs) pilots for inpatients in the new rural cooperative medical system in Yulin city of Shaanxi province. Methods The medical records of 33306 inpatients discharged from the 3 pilot hospitals between January and July in 2017 were analyzed, aided by expert discussions, on-site assessment and medical records examinations. Results By the end of July 2017, the DRGs grouping tool had been running stably. The DRGs enrollment rates of discharged inpatients were all up to 99% in the 3 pilot hospitals. The coefficient of variation ( CV) was higher than 1 only in a few DRGs. The average length of stay and the average hospitalization expenses growth rate were both found declined. However, there also exist problems in the pilots, namely incomplete regulations for DRGs, low clinical path coverage rate, hysteretic supervision and assessment, uneven quality of medical records management and so on. Conclusions The pilots operated smoothly as evidenced in their initial success. Yet the following recommendations were raised for the improvements: To strengthen the organization and leadership to improve the DRGs related supporting system in pilot hospitals; To strengthen the promotion and application of clinical paths for standardization of the medical service process;To improve the DRGs assessment program and establish DRGs operation monitoring and tracking analysis system; To strengthen the training of medical record coding staff to improve continuously the quality of medical records.

Objective To retrospectively analyze the relationship between progression free survival (PFS) and overall survival (OS) in patients with non small cell lung cancer (NSCLC), and to detect the influence of plasma fibrinogen and D-dimer levels before treatment in the prognosis of advanced stage (stageⅢB-Ⅳ) of NSCLC. Methods The study comprised 134 NSCLC patients with clear pathological diagnosis. All patients were grouped by plasma fibrinogen and D-dimer levels before treatment. We set the normal values of fibrinogen as≤4 g/L and D-dimer as≤500μg/L(FEU). Patients with normal levels of fibrinogen and D-dimer were grouped into low risk group, patients with elevated fibrinogen or D-dimer were grouped into median risk group, and patients with both elevated values were grouped into high risk group. Chi-square test and one way ANOVA analysis were used to analyze the clinicopathologic features of different groups. The OS and PFS in different groups were analyzed by Kaplan-Meier analysis. Univariate analysis of PFS and OS were conducted. Then multivariate analysis was conducted with the Cox regression model in three groups. Results The clinicopathologic features showed no differences between different groups. There were significant differences in OS and PFS between high risk group and other groups. In the survival curves, the high risk group showed poor prognosis. The result of multivariate analysis showed that clinical stage (OS:RR=1.846, 95%CI 1.150-2.964,P=0.011; PFS:RR=1.762, 95%CI 1.190-2.609, P=0.005) and grouped by fibrinogen and D-dimer (OS:RR=1.415,95%CI 1.050-1.908,P=0.023;PFS:RR=1.373,95%CI 1.070-1.761,P=0.013) were prognostic factors for patients with NSCLC. Conclusion The plasma fibrinogen and D-dimer levels before treatment are closely related with the prognosis of NSCLC patients. And a high plasma fibrinogen and D-dimer levels before treatment are associated with poor prognosis in advanced stage of NSCLC patients.
