Objective To explore the value of pelvic CT angiography(CTA)digital three-dimensional reconstruction model(abbreviated as"three-dimensional model")in the diagnosis of female pelvic mass.Methods A total of 98 patients with pelvic mass who were hospitalized and operated in Xi'an People's Hos-pital(Xi'an Fourth Hospital)from January 2021 to April 2023 were selected.All patients underwent B-ultra-sound and CTA examination before operation,and the original data of CTA were collected.The digital three-dimensional model of pelvic mass was established by three-dimensional reconstruction software,and the source of pelvic mass was judged according to the blood supply of pelvic mass.Taking postoperative pathological di-agnosis as the gold standard,the coincidence rate between different preoperative diagnosis methods(B-ultra-sound,CTA examination and three-dimensional model)was compared.The receiver operating characteristic(ROC)curve was plotted to evaluate the efficacy of different preoperative diagnostic methods in judging the ovarian origin of pelvic tumors.Results A total of 130 pelvic masses were included in 98 patients,and the average maximum diameter of the mass was(71.61±3.03)mm,including 83 ovarian masses and 47 non-ovarian masses.Taking postoperative pathological diagnosis as the gold standard,the diagnostic coincidence rate of the preoperative three-dimensional model was 72.31％,which was higher than that of B-ultrasound(58.46％)and CTA(52.31％),and the differences were statistically significant(P＜0.001).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,Kappa value,and area under the ROC curve were 79.51％,91.49％,94.29％,71.67％,83.85％,0.67 and 0.855,respectively,when the three-dimensional model showed that the blood supply of the mass originated from ovarian artery or uterine artery-ovarian branch.Conclusion The three-dimensional model of pelvic CTA can directly display the blood supply source,characteristics of mass,and the relationship between mass and adjacent organs,which can guide the clinical treatment.It has certain clinical value to judge the ovarian origin of pelvic mass by using ovarian artery and uterine artery-ovarian branch.

Objective:To evaluate the therapeutic effects of Yufu ointment for acute radiation-induced skin injury. Methods:We enrolled a total of 104 patients with malignant tumors who developed acute skin injury of grade 2-3 during or after the first course of radiotherapy from June 2019 to February 2023. The observation group ( n=53) and control group ( n=51) received external application of Yufu ointment and Shirun Shaoshang ointment, respectively. We recorded the changes in the grade of skin injury and associated symptoms (such as pain, itching, and burning sensation) and healing speed and time for the two groups. Results:A total of 102 patients completed the study, with 53 cases in the observation group and 49 cases in the control group. The incidence rate of moisture skin lesions in the observation group was significantly lower than that in the control group (62.26% vs. 83.67%, P<0.05). The healing speed of moisture skin ulcerations was significantly faster in the observation group than in the control group (1.67 cm 2/d vs. 0.55 cm 2/d, P<0.05). The observation group had a significantly shorter time to skin injury healing than the control group (10.40 d vs. 14.41 d, P<0.05), significantly different for skin injury of grade 2 (10.21 d vs. 17.57 d, P<0.05) but not for skin injury of grades 2.5 and 3 ( P>0.05). Regarding clinical symptoms, both groups experienced significant reductions in pain and burning sensation scores after treatment ( P<0.05); the grade of itching was significantly decreased for the observation group ( P<0.05), but had no significant change for the control group after treatment ( P>0.05). Conclusions:Yufu ointment can significantly alleviate secondary damage for patients with acute radiation-induced skin injury, by accelerating the healing process and relieving symptoms such as pain, itching, and burning sensation with good tolerability, which deserves further promotion.

There are still many existing problems in the training of medical undergraduates and microsurgery talents in China, such as lack of scientific research ability and scientific literacy of medical undergraduates, insufficient practical ability, short of scientific research opportunities for medical undergraduates, and inadequate talent reserve in microsurgery. In view of the above shortcomings, Wannan Medical College has established a training course on microneurosurgery technology for medical undergraduates, and made a preliminary exploration to solve the above problems. Through the training, undergraduates not only improve their practical ability, but also stimulate their interest in microsurgery, which will help them adapt to clinical and scientific research work at an early stage. Neurosurgical microscopic technology training with emphasis on extracurricular expansion as main content, plays an important role in the cultivation of undergraduate microscopic skills, the establishment of basic theories of neurosurgery, the improvement of scientific research accomplishment and the expansion of extracurricular vision.

Objective:To comprehensively evaluate the clinical application status of oral movement intervention in preterm infants, analyze the obstacles in the process of clinical application of the best evidence and formulate countermeasures, so as to provide reference for clinical evidence transformation.Methods:Based on the theoretical guidance of the "Clinical Application Model of Evidence" of the Joanna Briggs Institute (JBI) Evidence-Based Health Care Center in Australia, 12 pieces of the best evidence for oral movement intervention in premature infants were included, and 13 review indicators were formulated. From May to July 2021, a status review was conducted in Department of Neonatology in Suzhou Hospital Affiliated to Nanjing Medical University. The Ottawa Model of Research Use (OMRU) was used to analyze the barriers and facilitators in the process of evidence application and formulate effective intervention strategies and action plans.Results:Among the 13 reviewed indicators, only 2 items had a compliance rate of 100%, 2 items had a compliance rate of more than 60%, 6 items had a compliance rate of less than 60%, and 3 items had a compliance rate of 0. The main obstacle factors were lack of standardized process and assessment tools, lack of oral motor intervention related knowledge and training for preterm infants, increased clinical workload due to evidence transformation and the low level of knowledge and action among medical staff. The main promoting factors were support from managers for the development and reform of evidence-based learning, good learning atmosphere for doctors and nurses, departments with material and hardware conditions for evidence transformation, effective evidence, and parents' willingness to accept the reform. Through analysis, countermeasures were drawn up to formulate feasible and suitable standardized procedures and introduce assessment tools. Managers formulated and implemented incentive policies, adopted various training methods, strengthened quality supervision in the process of evidence transformation, timely gave feedback of progress results and improved human resource allocation.Conclusions:There is a certain gap between the best evidence of oral movement intervention in premature infants and the current clinical nursing practice. It is necessary to formulate corresponding countermeasures according to the obstacle factors and promoting factors, promote the evidence transformation and constantly promote the evidence-based practice of oral movement intervention in premature infants.

Objective:To analyze the predictive value of enhanced MRI in the outcome of prolapsed and sequestrated lumbar disc herniation through a retrospective analysis.Methods:A retrospective analysis of the data of 64 patients with prolapsed and sequestrated lumbar disc herniation from January 2015 to December 2018, including 38 males and 26 females; age 35.72±12.44 years (range, 22-64 years) ; 43 cases of prolapsed type, 21 cases of sequestrated type. Conservative treatment was the first choice for all patients, in case of surgical indications during the treatment, percutaneous endoscopic lumbar discectomy or fenestration discectomy will be performed. Enhanced MRI was performed at the first and last inspections, the volume of the protrusion, the thickness of rim enhancement (Tr), and the extent of rim enhancement (Er) were measured and calculated at the same time. According to the ring around the protrusion, the size of the rim-enhancement area was divided into type I-III; then compared the relationship between the rim-enhancement signal differentiation and the resorption rate of protrusions, and the correlation between Tr, Er values and the resorption rate of protrusions during the initial inspection.Results:Among the 64 patients, 42 patients completed conservative treatment, and 22 received surgical treatment. According to the rim-enhancement signal differentiation, 23 cases were treated conservatively for type I, 3 cases were treated by surgery; 16 cases were treated for type II conservatively, 7 cases were treated by surgery; 3 cases were treated for type III conservatively, and 12 cases were treated by surgery. All patients were followed up for 12 to 34 months. Among 42 conservatively treated patients, The volume of the protrusion before treatment was 2 645.67±690.86 mm 3, and the volume of the protrusion after treatment was 842.76±573.35 mm 3. The volume of protrusions before and after treatment was statistical significance ( t=11.897, P<0.001), Tr was 1.38±0.83 mm, and Er was 73.08%±34.39%, the resorption rate of protrusions was 65.10%±24.50%, and 39 cases (92.86%, 39/42) reached the standard for protrusion resorption (resorption rate ≥30%); 23 cases of type I , the resorption rate was 76.54%±18.62%; 16 cases of type II had an resorption rate of 56.81%±21.44%; 3 cases of type III had an resorption rate of 21.58%±12.19%. The resorption rate of type III were compared by single factor analysis of variance, and the difference was statistically significant ( F=12.885, P<0.001); 32 cases of both type I and II (82.05%, 32/39) had significant resorption (resorption rate ≥50%), and no case of type Ⅲ had significant resorption, comparing with type I and II, the difference was statistically significant ( P=0.010); Tr was positively correlated with resorption rate ( r=0.569, P<0.001), Er was positively correlated with resorption rate ( r=0.677, P<0.001). Conclusion:Under close clinical observation, parts of the prolapsed or sequestrated lumbar disc herniations can be conservatively treated, and the herniated disc can be resorption in many people and the clinical symptoms were alleviated. Rim-enhancement signal differentiation by enhanced MR has a better predictive value for the outcome of the herniation, type I is more prone to resorption, preferred conservative treatment, type Ⅲ is not easy to resorption, preferred surgery treatment, and the higher thickness of rim enhancement, the greater extend the rim-enhancement, the more prone to resorption phenomenon.

Objective:To understand the status quo of male nurses′ resilience, social support and simple coping styles in Heilongjiang Province, and to analysis the mediating effect of resilience between social support and simple coping styles.Methods:The questionnaire star was used to survey 780 nurses from 13 departments including such as intensive care unit, emergency department, psychiatric department, and operating room etc in Harbin 9 hospitals from November to December 2018 by convenience sampling. The self-made general information questionnaire, Connor-Davidson Resilience Scale (CD-RISC), Social Support Rating Scale (SSRS) and Simplified Coping Style Questionnaire (SCSQ) were used to assess the resilience, social support and simple coping style.Results:The average score of resilience of male nurses in Heilongjiang Province was (72.36±16.69) points, the average score of social support was (37.21±8.70) points, the average items score of positive coping style was (2.18±0.52) points, negative coping style items score was (1.53±0.76) points. Social support and positive coping styles all showed a significant positive correlation with resilience ( r values were 0.432, 0.747, P<0.01). The results of mediation analysis showed that resilience played a part of mediation between social support and active coping styles. The mediation effect was 21.05%, accounting for 63.21% of the total effect. Conclusion:In order to effectively maintain the mental health of male nurses in Heilongjiang Province and improve their active coping level, it is necessary to ensure that the nurses have a good level of resilience.

Objective:To evaluate the clinical value of neutrophil/lymphocyte ratio (NLR) in early prediction of the incidence of sepsis-induced organ dysfunction and 28-day mortality.Methods:A retrospective study was conducted in 815 adult patients with sepsis admitted to the department of critical care medicine of the First Affiliated Hospital of China Medical University from January 2017 to December 2019. The clinical data including age, gender and complication were collected, and the peripheral blood routine indexes at 24, 48 and 72 hours after the diagnosis of sepsis were collected, and the NLR was calculated. The primary endpoint of the study was the incidences of sepsis related acute kidney injury (AKI), acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC) and acute liver failure (ALF); the secondary endpoint was the 28-day in-hospital mortality in septic patients with organ dysfunction. Univariate and multivariate Logistic regression were used to analyze the risk factors of organ dysfunction and 28-day mortality in patients with sepsis, the receiver operating characteristic curve (ROC curve) was drawn and the area under the ROC curve (AUC) was calculated to evaluate the predictive value of NLR for organ dysfunction and 28-day mortality in patients with sepsis.Results:A total of 714 patients with sepsis were enrolled for final statistical analysis. There was no significant difference in NLR at 24, 48 and 72 hours in patients with or without organ dysfunction (such as AKI, ARDS, DIC and ALF). Logistic regression analysis showed that there was no significant difference in NLR at 24 hours with 28-day in-hospital mortality [odds ratio ( OR) = 1.006, 95% confidence interval (95% CI) was 0.994-1.019, P = 0.323]. However, NLR at 48 hours and 72 hours had a significant difference with 28-day mortality (48 hours: OR = 1.026, 95% CI was 1.013-1.040, P = 0.000; 72 hours: OR = 1.021, 95% CI was 1.005-1.037, P = 0.010), which suggested that NLR at 48 hours and 72 hours after diagnosis were independent risks factor for 28-day mortality in patients with sepsis. ROC curve showed that the AUC of NLR at 48 hours was 0.598, 95% CI was 0.540-0.658, P = 0.02; when the cut-off value was 10.1, the sensitivity and specificity for predicting 28-day mortality was 75.2% and 58.0%, respectively; the AUC of NLR at 72 hours was 0.595, 95% CI was 0.536-0.655, P = 0.03; when the cut-off value was 9.24, the sensitivity and specificity for predicting 28-day mortality was 75.3% and 59.9%, respectively. Conclusions:NLR cannot predict the occurrence of AKI, ARDS, DIC and ALF in sepsis in early stage. NLR has a certain clinical value in predicting 28-day mortality in patients with sepsis, but its predictive efficiency is low.

Invasive fungal infections (IFIs) represent a growing public concern for clinicians to manage in many medical settings, with substantial associated morbidities and mortalities. Among many current therapeutic options for the treatment of IFIs, amphotericin B (AmB) is the most frequently used drug. AmB is considered as a first-line drug in the clinic that has strong antifungal activity and less resistance. In this review, we summarized the most promising research efforts on nanocarriers for AmB delivery and highlighted their efficacy and safety for treating IFIs. We have also discussed the mechanism of actions of AmB, rationale for treating IFIs, and recent advances in formulating AmB for clinical use. Finally, this review discusses some practical considerations and provides recommendations for future studies in applying AmB for combating IFIs.
