Objective:To deeply understand the real experience of family members of patients in the neurosurgery intensive care unit during the period of accompanying them, and to provide reference for managers to formulate nursing countermeasures to improve the coping ability of family members.Methods:Descriptive phenomenological research method in qualitative research was adopted to conduct in-depth interviews with family members of 12 patients admitted to a neurosurgery intensive care unit in Shanghai, manage the interview data with Nvivo11 software, and use Colaizzi's seven-step analysis method to summarize and analyze the topic.Results:There were four themes: adhere to and do not give up, adhere to was due to the trust and affirmation of the medical care, do not give up was because it was difficult to give up blood kinship, adhere to the hope of life because of patients; timing change of emotional experience, first aid period: helpless to rescue and expecting the condition to stabilize, complication peak: understanding the characteristics of the disease and paying attention to the treatment progress, stable period: uncertain prognosis and desire for emotional companionship.The powerlessness of the future; learn to self psychological adjustment.Conclusions:The family members of patients with severe neurological diseases have both negative experience and positive feelings, and the accompanying experience and needs at different stages of the disease are changing dynamically. According to the cognition and needs of the family members, exploring and developing palliative medicine, tapping the potential of the family members from a positive perspective and improving coping ability are one of the ways to maintain the stable mental health of the family members.

Objective Study the endobronchial ultrasound features of mediastinal tubercular lymphadenopathy and sarcoidosis to probe a new method for the differential diagnosis. Methods The endobronchial ultrasound features of 74 lymph nodes in 16 mediastinal tubercular lymphadenopathy and 30 sarcoidosis patients diagnosed in our department were studied retrospectively, and the sizes, borders, fusion and echo features of mediastinal tubercular lymphadenopathy were compared to sarcoidosis. Results Both of the long size and the short size of mediastinal tubercular lymphadenopathy were smaller than sarcoidosis [(15.77 ± 4.10) vs (19.76 ± 5.83), t = 3.28, P = 0.021;(12.67 ± 4.09) vs (16.81 ± 5.54), t = 3.56, P = 0.001]. And the following features were statistically significant of tubercular lymphadenopathy as compared to sarcodosis: indistinct borders, fusion of lymph nodes, hyperechoic echotexture and patchy anechoic/hypoechoic areas [50.0% (11/22) vs 17.3% (9/52), χ2 = 8.38, P = 0.004; 18.2%(4/22) vs 0.0% (0/52), P = 0.008; 50.0% (11/22) vs 0.0% (0/52), P = 0.000; 63.6% (14/22) vs 0.0% (0/52), P = 0.000, respectively). However, there was no significant difference in the existence of central hilar structure [9.1% (2/22) vs 19.2% (10/52), P = 0.491] between mediastinal tubercular lymphadenopathy and sarcoidosis. Conclusions The endobronchial ultrasound features of mediastinal lymph nodes, including sizes, borders, fusion, hyperechoic echotexture and patchy anechoic/hypoechoic areas are helpful in the differential diagnosis of mediastinal tubercular lymphadenopathy and sarcoidosis.

Objective To determine potential gene-gene interactions of TNF-? and VDR loci with outcomes of hepatitis B virus(HBV) infection.Methods A total of 391 chronic hepatitis B(HB) patients as a case group and 212 HBV self-limited infected subjects as a control group were recruited to conduct a case-control study.TNF-?-238G/A,-857C/T,-863C/A,VDR-TaqⅠT/C and FokⅠC/T gene polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).The interactions between TNF-? and VDR genes were analyzed by multiple model.Results There were positive gene-gene interactions between TNF-?-238 GA and FokⅠ CT/CC(ORint=4.04),between-863 CC and-857 CC(ORint=1.26) and between-857 CC and FokⅠ CT/CC(ORint=1.37),respectively,which increase the risk of chronic hepatitis B.There were negative gene-gene interactions between TNF-?-238 GA and-857 CC(ORint=0.92)and between FokⅠ CT/CC and TNF-?-863 CC(ORint=0.95),which decrease the risk of chronic hepatitis B.Conclusion Interaction between TNF-? loci and VDR loci potentially increase the risk of chronic hepatitis B after HBV infection.

Objective:To analyze the clinical features and follow-up results of children with acute exogenous lipoid pneumonia (ELP), and to investigate the diagnosis strategy, treatment and risk factors of ELP.Methods:The clinical features, imaging manifestations, results of bronchoalveolar lavage fluid (BALF), treatment methods and prognosis of 41 ELP inpatients in Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from May 2013 to May 2018, were summarized and analyzed, and the related literature was reviewed.Results:(1) Among 41 patients, 29 cases were male and 12 cases were female.The age of onset ranged from 4 to 53 months.Most of them (35/41 cases, 85.4%) were less than 3 years old, and the majority were aged 1 to 2 years (23/41 cases, 56.1%). (2) The grease taken by children by accident included perfume oil (11 cases), white electric oil (7 cases), electric mosquito oil (5 cases), lubricating oil (5 cases), paraffin oil (4 cases), gasoline/diesel oil (3 cases), kerosene (2 cases), cod-liver oil (2 cases), sewing machine oil (1 case), and unclear oil (1 case). (3) The main clinical manifestations were cough (26/41 cases, 63.4%), shortness of breath (23/41 cases, 56.1%), fever (17/41 cases, 41.5%), cyanosis with hypoxemia (15/41 cases, 36.6%), wheezing (9/41 cases, 22.1%), respiratory distress (9/41 cases, 22.1%), pulmonary hemorrhage (6/41 cases, 14.7%), feeding difficulties and transient vomiting (4/41 cases, 9.8%). Some cases showed no symptoms (3/41 cases, 7.3%). (4) Chest X-ray mainly showed bilateral pulmonary exudative changes or pulmonary consolidation.The most common sign of high-resolution computerized tomography (HRCT) was local or extensive exudation, often accompanied by pulmonary consolidation (18/41 cases, 43.9%). The most common affected sites were bilateral lower lobes (8/41 cases, 19.5%), followed by right lower lobes (3/41 cases, 7.3%), right middle lobes (2/41 cases, 4.8%) and left lower lobes (2/41 cases, 4.8%). Other signs included alveolar changes, hyperventilation, ground glass changes, and nodule formation.(5) Seven children needed mechanical ventilation due to respiratory failure, and all patients underwent bronchoalveolar lavage (BAL). All patients recovered without death, with (11.67±4.90) days of hospitalization, and the hospitalization time of ELP patients with adenovirus infection was (19.25±5.93) days.Nine of them were lost to follow-up (8 cases were mild and 1 case was severe). The symptoms of the remaining children disappeared within 1 week to 1 month.The lung images of 21 cases returned to normal within 1 month after discharge, 7 cases returned to normal within 3 months after discharge, and 4 cases returned to normal after 6 months.Conclusion:The clinical manifestations and lung imaging of children with acute ELP have no specificity.Pulmonary imaging of severe patients shows multiple lobes involved, and consolidation and vacuolar changes may occur.Most patients have a favorable prognosis.Co-infection, especially adenovirus infection, may be a risk factor for acute ELP in children.BAL can play a role in both diagnosis and treatment, and its combination with local/systemic glucocorticoid therapy is effective for severe acute ELP.

Objective:To further understand the real experience of the nurse in the rotation of NICU in neurosurgery.Methods:Qualitative research method was used to analyze the reflective diary of 26 nurses and the semi-structured interview data of 8 nurses.Results:Three primary themes and 11 secondary themes were extracted from the real experience of rotation of nurses in the neurointensive care unit: department integration and mental process, role competency and influencing factors, career expectations and coping strategies.Conclusions:At present, the integration process of the nurses in the neurointensive care unit is slow. Influenced by many factors, it is difficult to change their roles. It is the direction that nursing managers should pay attention to establish a diversified discipline training system and create a better organizational commitment

Objective To summarize and explore the current state,hotspots,and trends in the field of surgical treatment for intracerebral hemorrhage(ICH)over the past decade through a bibliometric and visualization analysis of relevant literature.Methods Relevant Chinese and English literature on the surgical treatment of ICH,published from January 1,2014 to April 1,2024,was retrieved and screened from CNKI and Web of Science databases.Visualization analysis was conducted using CiteSpace,VOSviewer,and other software to analyze the number of published papers,authors,countries,institutions,etc.Social network analysis diagrams of authors,keyword clustering network analysis diagrams,keyword burst strength,and keyword timeline maps were also utilized.Results(1)A total of 3 456 relevant papers were included,with 2 173 in Chinese and 1 283 in English.From 2014 to 2021,the annual number of Chinese publications on ICH surgery was higher than that of English publications,but the number of Chinese publications began to decline from 2016.The number of English publications showed an overall increasing trend.(2)A total of 6 367 authors were identified from the English literature,with notable collaboration networks led by researchers such as Mocco J,Hanley DF,Ziai WC,You C,and Tang ZP.The Chinese literature included 6 522authors,with prominent collaboration networks led by Wang LK,Cai Q,Ku HB,Zhang S,and Zhu SQ.(3)Analysis of the countries involved in the English literature showed that 31 countries participated in research on ICH surgery,with China leading in the number of publications(505),followed by the United States(330)and Germany(106).The top three countries in centrality were the United States(0.32),China(0.16),and Canada(0.11).The top three institutions in English literature publications were Johns Hopkins University(51 papers),Ohio State University(39 papers),and Harvard University(38 papers).In China,Sichuan University(32 papers),Huazhong University of Science and Technology(30 papers),and Capital Medical University(27 papers)had multiple English publications;Wuhan University People's Hospital(15 papers),Affiliated Hospital of Guizhou Medical University(13 papers),and Affiliated Hospital of Yan'an University(13 papers)had multiple Chinese publications.There was close collaboration among research institutions in the English literature,whereas Chinese researchers often established research teams within their medical units with relatively less collaboration between teams.(4)Research on ICH surgery primarily focused on surgical methods,complications,and comprehensive perioperative treatment.Research hotspots included hypertensive ICH,minimally invasive surgical techniques,and perioperative management and treatment."neuroendoscopy"was the most recent emergent keyword in Chinese literature with high centrality and the strongest burst strength,while"randomized trial"had the highest burst strength in English literature.Research trends included the integration of artificial intelligence with minimally invasive techniques to optimize ICH surgery management and treatment strategies,analysis of risk factors,and evaluation of imaging value.Conclusions Over the past decade,the overall publication volume on the surgical treatment of ICH has been in a stable development phase,with research directions covering surgical techniques,diagnosis and treatment,evaluation,and management.Core research teams led by key authors were the main contributors to the publications.Future research hotspots and trends in ICH surgery may include the optimization of surgical techniques,complication management,large-scale multicenter clinical trials and integration of artificial intelligence with minimally invasive techniques.

Objective To identify risk factors of systemic inflammatory response syndrome (SIRS) after percutaneous nephrolithotomy (PCNL).Methods We retrospectively reviewed 438 renal calculi patients after PCNL from August 2015 to July 2016.Among them,there were 251 men and 187 women,the mean age was (49.4 ± 11.1) years.The positive preoperative urine WBC,culture and nitrite rates were 29.7％ (130),12.1％ (53) and 15.1％ (66),respectively.The stone size was (851.2 ± 663.6) mm2,the stone CT value was (960.4 ± 303.4) HU,the operative time was (63.5 ± 33.4) min,124 (28.3 ％) were infection stones and multiple-tracts PCNL was performed in 69 (15.8％) patients.Univariate and multivariate logistic regression analysis were used to analyze perioperative predictors after PCNL.Results Thirty-nine patients developed SIRS (8.9％) after PCNL.The univariate analysis showed that positive preoperative urine WBC,nitrite,culture,operation time,stone size and transfusion had significantly impacts on the outcome of postoperative SIRS after PCNL (P ＜ 0.05).Multivariable logistic analysis showed that positive preoperative urine nitrite (OR =5.990,P ＜ 0.001),stone size (OR =2.251,P =0.027) and transfusion (OR =7.501,P =0.007) were independently related to the postoperative SIRS.Conclusion The positive preoperative urine nitrite,stone size and transfusion are independent risk factors for postoperative SIRS after PCNL.

Objective:To investigate the characteristics of distribution and drug resistance of urinary bacteria in the mid-stream urine of patients with infectious stones.Methods:The retrospective study analyzed the clinical data of 254 patients with infectious stones in the First Affiliated Hospital of Guangzhou Medical University from September 2016 to September 2018. All patients were treated with PCNL. Overall, there were 101 male and 153 female patients, with the mean age of(51.5±12.3) years, and the mean stone burden of 1443.5(660.8, 2837.5) mm2. There were 58 (22.8%) patients with hypertension, 17(6.7%) patients with diabetes and 195(76.8%)with hydronephrosis. The mid-stream urine samples were obtained for bacterial culture and susceptibility test, and the results of urine culture and antimicrobial susceptibility were recorded and analyzed.Results:Of 254 patients involved in this study, 89(35.0%) were positive and 165 (65.0%) were negative for urinary bacterial culture of the mid-stream. The proportion of patients with positive urine bacterial culture of the mid-stream who had positive urine leucocytes, positive urine nitrite and postoperative pyrexia were 86.5%(77/89), 64.0%(57/89), 25.8%(23/89), respectively, which was higher than that of patients with negative urine bacterial culture of the mid-stream [50.3%(83/165), 14.5%(24/165), 14.5%(24/165), P<0.05]. Four teen kinds of bacteria were detected from the mid-stream urine, and the three bacteria with the highest detection rate in turn were Escherichia coli of 38.2%(34/89), Proteus mirabilis of 15.7%(14/89), and Pseudomonas aeruginosa of 11.2%(10/89). The results of this study showed that three common bacteria had high resistance to drug including Cefazolin, Cefuroxime, Cefuroxime ester, Ampicillin and Co-trimoxazole (all resistance rate>40%). The resistance rates of Escherichia coli and Pseudomonas aeruginosa to Ciprofloxacin and Levofloxacin were higher than or equal to 40%. The resistance rates of Escherichia coli and Proteus mirabilis to meropenem, imipenem, ertapenem, piperacillin/tazobactam and amikacin were all lower than 10%. In addition, the resistance rates of Escherichia coli to nitrofurantoin and tigecycline and Proteus mirabilis to tobramycin, aztreonam and cefoxitin were all less than 10%. The resistance rates of Pseudomonas aeruginosa to ceftazidime, cefepime, gentamicin and aztreonam were less than 10%. Conclusions:The highest detection rate of urinary bacteria in culture of the mid-stream with infectious stones are Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa, all of which showed high resistance to Ampicillin, Cotrimoxazole, and some cephalosporins. Escherichia coli and Pseudomonas aeruginosa showe high resistance to Ciprofloxacin and Levofloxacin, and all of the three bacteria have low resistance rates to some β-Lactamase inhibitor complex and carbapenems, suggesting a reference for clinical empirical medical treatment.
