Objective To explore the clinical features of the patients with prolactinoma and changes of pituitary function before and after surgery.Methods The clinical data of 72 patients with prolactinoma admit-ted and operatively treated in the neurosurgery department of the Second Hospital of Lanzhou University from June 2018 to January 2023 were analyzed retrospectively and their clinical characteristics and change character-istics of pituitary function before and after surgery were summarized.Results (1) Most of the patients with prolactinoma included in this study were macroadenomas,and its clinical manifestations were mainly tumor compression symptoms such as headache and vision diminution;(2) there was a statistically significant differ-ence in tumor invasiveness between the patients with preoperative PRL≥200.000 ng/mL and those with pre-operative PRL<200.000 ng/mL (P<0.05).(3) The PRL level of prolactinoma after surgical treatment in the patients with prolactinoma was significantly decreased compared to preoperative level,and the difference was statistically significant (P<0.05).(4) Among 72 patients,44 patients already had hypopituitarism before surgery,the pituitary function in 2 cases returned to normal,15 cases of hypopituitarism were newly increased and there were 57 cases of postoperative hypopituitarism.Preoperative hypopituitarism was positively correla-ted with postoperative hypopituitarism (r=0.433,P<0.05).By the logistic multifactorial regression analy-sis,the tumor maximal diameter was a risk factor for hypopituitarism occurrence before and after surgery (P<0.05),and the tumor invasiveness was a risk factor for postoperative hypopituitarism (P<0.05),where-as the BMI and PRL level,age,gender,and whether or not pituitary apoplexy occurring had no relationship with hypopituitarism (P>0.05).(5) The gonadal axis was the most common hypofunction in uniaxial sys-tem,and gonadal+thyroid axis was the most common biaxial involvement.Conclusion The surgical treat-ment in the patients with prolactinoma is effective for relieving tumor mass occupation and improving hyperp-rolactinemia.The pituitary function should be fully evaluated before and after surgery.For the patients with hypopituitarism occurrence,the hormone replacement therapy should be given in time,and at the same time the hormonal changes should be closely monitored.

Objective To discuss the nursing cooperation method in CT-guided pulmonary nodule localization using indocyanine green combined with methylene blue.Methods A total of 81 patients,who needed to receive pulmonary nodule localization before thoracoscopic resection,were enrolled in this study.The nursing cooperation measures,including the preparation and injection of indocyanine green combined with methylene blue,breathing mode coordination,position management,precise localization coordination,and psychological care,were analyzed.Results Successful nodule localization was accomplished in all patients.No statistically significant difference in the incidence of adverse events existed between the patients with different clinical characteristics(P＞0.05).The gender,age,lesion site,nodule size,nodule-pleura distance,posture during puncturing and needle path route were not the factors influencing the occurrence of adverse reactions in patients receiving CT-guided pulmonary nodule localization using indocyanine green combined with methylene blue.Conclusion In performing CT-guided pulmonary nodule localization using indocyanine green combined with methylene blue,the nursing cooperation method carries generality and stability,which is suitable for patients with different clinical characteristics.

Objective:To reassess the prognostic value of minimal residual disease (MRD) and IKZF1 gene deletions in adults with B-cell acute lymphoblastic leukemia (B-ALL) who received pediatric-specific chemotherapy regimens during the Nanfang Hospital PDT-ALL-2016 trial.Methods:We retrospectively analyzed the prognosis of 149 adult patients with B-ALL who were admitted to Nanfang Hospital from January 2016 to September 2020. Prognostic factors were identified using Cox regression models.Results:The complete remission rate was 93.2% in 149 patients, with a 5-year overall survival (OS) rate of (54.3±5.0) % and a cumulative incidence of relapse (CIR) of (47.5±5.2) %. The Cox regression analysis revealed that MRD positivity at day 45 (MRD 3) after induction therapy was independently associated with relapse risk ( HR=2.535, 95% CI 1.122-5.728, P=0.025). Deletion of IKZF1 gene was independently associated with mortality risk ( HR=1.869, 95% CI 1.034-3.379, P=0.039). Based on MRD 3 and IKZF1 gene status, we categorized adult patients with B-ALL into the low-risk (MRD 3-negative and IKZF1 gene deletion-negative) and high-risk (MRD 3-positive and/or IKZF1 gene wild type) groups. The 5-year OS and CIR rates were (45.5±6.0) % vs (69.4±8.6) % ( P<0.001) and (61.6±8.3) % vs (25.5±6.5) % ( P<0.001), respectively, in the high-risk and low-risk groups, respectively. The multivariate analysis showed that the high-risk group was an independent risk factor for OS ( HR=3.937, 95% CI 1.975-7.850, P<0.001) and CIR ( HR=4.037, 95% CI 2.095-7.778, P<0.001) . Conclusion:The combined use of MRD and IKZF1 gene in prognostic stratification can improve clinical outcome prediction in adult patients with B-ALL, helping to guide their treatment.

Graves'ophthalmopathy(GO),also known as thyroid-associated ophthalmopathy,is an organ-specific au-toimmune disease that ranks first in the incidence of adult orbital diseases.GO has complex clinical manifestations,and dry eyes are a common cause of eye discomfort in patients with this disease.The pathogenesis of concurrent dry eyes is still unclear.It is currently believed that ocular surface damage in patients with GO is a direct factor leading to the occurrence and development of dry eyes.In addition,immunity and inflammation,and intestinal flora imbalance also play a role.Mul-tiple factors interact to form a vicious cycle,which further aggravates dry eyes.This article reviews the research results re-lated to the pathogenesis of GO complicated by dry eyes,aiming to provide ideas for clinical treatment and further research in the field.

Objective:To explore the efficacy of sequential and concurrent chemoradiotherapy in the treatment of advanced non-small cell lung cancer (NSCLC) in the elderly, and to analyze the influencing factors of prognosis and outcome.Methods:The clinical data of 195 elderly patients with advanced NSCLC admitted to Beijing Shijingshan Hospitaland and Beijing Shijitan Hospital from March 2015 to March 2018 were retrospectively analyzed. They were divided into the concurrent chemoradiotherapy (100 cases) and the sequential chemoradiotherapy (95 cases) according to different chemoradiotherapy regiments. The short-term efficacy, 3-year survival, influencing factors of prognosis and toxic and adverse effects of the two groups were compared.Results:The objective response rate in the concurrent chemoradiotherapy group was significantly higher than that in the sequential chemoradiotherapy group: 61.00%(61/100) vs. 44.21%(42/95), there was statistically difference ( χ2 = 5.51, P<0.05). The 2-year and 3-year survival rate in the concurrent chemoradiotherapy group were 52.00% and 23.00%, which were significantly higher than those in the sequential chemoradiotherapy group: 32.60%, 11.60%, there were statistically differences ( P<0.05). Multivariate analysis results showed that smoking, Karnofsky score<70, TNM stage Ⅲb, short-term efficacy and treatment methods/sequential chemoradiotherapy were independent risk factors ( P<0.05). The incidence of radiation esophagitis, bone marrow suppression and lung function damage in the concurrent chemoradiotherapy group were higher than those in the sequential chemoradiotherapy group: 45.00%(45/100) vs. 27.37% (26/95), 36.00%(36/100) vs. 22.11%(21/95), 48.00%(48/100) vs. 26.32%(25/95), there were statistically differences ( χ2 = 6.54, 4.55, 9.78; P<0.05). Conclusions:Concurrent chemoradiotherapy can improve the short-term efficacy, and improve the 2-year and 3-year survival rates in advanced NSCLC in elderly patients, but the adverse effects are significantly enhanced.

Objective:To investigate the differences between the mental clips placed intraoperatively and the tumor bed's target volume delineation of seroma based on CT scanning during radiotherapy for breast cancer patients who received breast-conserving surgery in the persuit of a better solution to determine the tumor bed position.Methods:The clinical data of 13 patients with early breast cancer who received postoperative radiotherapy after breast-conserving surgery at Beijing Shijingshan Hospital and Beijing Shijitan Hospital of Capital Medical University from December 2020 to January 2022 were retrospectively analyzed. They all had surgical clips implanted during the surgery. The following methods were used to delineate the target volume of tumor bed, including gross target volume delineation of tumor bed based on the mental clips (GTVtb-Clip), the tumor bed's gross target volume delineation of seroma based on CT scanning (GTVtb-Seroma), and the combination of both (GTVtb-C+S). The volume, diameter on three coordinate axis, neutral point displacement and conformability of these delineation methods were compared.Results:The volume of GTVtb-Clip, GTVtb-Seroma and GTVtb-C+S was (25±10) cm 3, (38±17) cm 3, (49±20) cm 3, and the differences were statistically significant (all P<0.05). The diameter on X axis was (4.7±1.2) cm, (5.3±1.4) cm, (5.7±1.6) cm, respectively in GTVtb-Clip, GTVtb-Seroma and GTVtb-C+S; the diameter on Y axis was (4.6±1.7) cm, (5.0±1.6) cm, (5.7±1.7) cm, respectively in GTVtb-Clip, GTVtb-Seroma and GTVtb-C+S; the diameter on Z axis was (4.4±1.5) cm, (5.2±1.4) cm, (5.6±1.4) cm in GTVtb-Clip, GTVtb-Seroma and GTVtb-C+S. The differences in the diameter of GTVtb-Clip and GTVtb-C+S on X,Y, Z axis were statistically significant (all P<0.05); the differences in the diameter of GTVtb-Seroma and GTVtb-C+S on X, Z axis were statistically significant (all P<0.05); the difference in the diameter of GTVtb-Clip and GTVtb-Seroma on X axis was statistically significant ( P<0.05) .Neutral point displacement was (5.8±1.6) cm, (5.5±1.9) cm, (6.0±1.7) cm, respectively of GTVtb-Clip, GTVtb-Seroma, GTVtb-C+S, and the difference was not statistically significant ( P>0.05). Conformability of GTVtb-Clip and GTVtb-Seroma, GTVtb-Clip and GTVtb-C+S, GTVtb-Seroma and GTVtb-C+S was 0.412±0.112, 0.525±0.095, 0.774±0.112,respectively, and the differences were statistically significant (all P<0.05). Conclusions:During radiotherapy after breast-conserving surgery for breast cancer, compared with the single method, the combination of GTVtb-Clip and GTVtb-Seroma can better cover the real tumor bed, thus reducing the omission of tumor bed and recurrence rate. CT position should better take place at 4 to 8 weeks for patients receiving radiotherapy after breast-conserving surgery, and target volume of tumor bed will be delineated based on the postoperative changes of both mental clips and seroma.

Objective To evaluate the design scheme of information data on critical care under the whole chain intelligent management and its clinical application value,and provide the basis for improving nurses' work mode and enhancing digital work efficiency.Methods A data connectivity channel was constructed by taking nurses as the main body and cooperating with computer engineers,which could capture target data automatically in the critical care information system,integrate into nursing documents,achieve the "whole chain intelligent control" of nursing data acquisition-summary statistics-quality control analysis,and generate structured handover content with one key.The time of nurses writing nursing records,the time of nurses analyzing data,the qualified rate of nursing documents,and the time of nurses preparing handover content were compared before and after the application of the "whole chain intelligent control".Results After applying the "whole chain intelligent control",the time of nurses writing nursing records,analyzing data,and preparing handover content in the observation group was all obviously shorter than that in the control group[the time of writing nursing records(minutes):14.60±3.97 vs.51.94±6.24;the time of analyzing data(minutes):9.19±4.19 vs.26.74±5.84;the time of preparing handover content(minutes):12.44±5.04 vs.66.99±6.77],with statistically significant differences(all P<0.01).The qualified rate of nursing documents in the observation group was remarkably higher than that in the control group[97.06％(66/68)vs.85.29％(58/68),P<0.05].Conclusion The construction of the mechanism of the "whole chain intelligent control" for information data on critical care can guarantee the accuracy of patient data,enhance nursing work efficiency,and give nurses more time for patients,thus laying the foundation for the establishment of fully digital intensive care unit(ICU)management.

Objective:To propose a markless patient setup workflow based on the optical surface monitoring system (AlignRT) and open-face mask immobilization for whole-course head tumor radiotherapy, assess the setup time and repositioning frequency of the proposed workflow, and conduct a comparative analysis of the differences, correlation, and consistency of the setup errors of the AlignRT and cone beam CT (CBCT) systems.Methods:A retrospective analysis was conducted for the data on the errors of 132 fractionated setup based on open-face mask immobilization of 33 head tumor patients. AlignRT-guided markless patient setup workflow was applied throughout the radiotherapy. Meanwhile, the body structures automatically generated by the treatment planning system were used as body references. The 6-degree-of-freedom (6DoF) setup errors (lateral, vertical, longitudinal, rotation, pitch, roll, and yaw directions), setup time, and repositioning frequency of the AlignRT and CBCT systems were recorded and analyzed. The Wilcoxon and Spearman analyses were used to statistically assess the differences and correlation of the setup errors of the two systems. Moreover, the Bland-Altman analysis was employed to evaluate the consistency of the two systems.Results:The 6DoF setup errors of CBCT were within the clinical tolerance (linear motions: -0.30 to 0.30 cm; rotational motions: -2.0° to 2.0°). The setup time and repositioning frequency of CBCT were (98 ± 31) s and 1.51% (2/132), respectively. There was no significant difference in setup errors between the two systems except those in x-axis ( Z = -3.11, P= 0.002), y-axis ( Z = -7.40, P<0.001), and Pitch ( Z= -4.48, P<0.001). There was a significant positive correlation between the setup errors along lateral ( rs = 0.47, P<0.001) and vertical ( rs = 0.29, P = 0.001) directions, rotation (Rtn; rs = 0.47, P<0.001), pitch (Pitch; rs = 0.28, P = 0.001) and roll (Roll; rs = 0.45, P<0.001) of the two systems. The 95% limits of agreement (95% LoA) of 6DoF setup errors were -0.12 to 0.09 cm, -0.07 to 0.17 cm, -0.19 to 0.20 cm, -1.0° to 0.9 °, -1.0° to 1.5°, and -0.9° to 1.0°, respectively. The 95% confidence interval (95% CI) of 95% LoA was -0.14 to 0.11 cm, -0.09 to 0.19 cm, -0.23 to 0.23 cm, -1.2° to 1.1°, -1.2° to 1.7°, and-1.0° to 1.1°, respectively, all of which were within the permissible error ranges. The 6DoF setup error difference of 3.41% (27/792< 5%) was beyond the 95% LoA. The maximum absolute differences of 6DoF setup errors within the 95% LoA were 0.12, 0.16, 0.19 cm, 0.9°, 1.5°, and 1.0°, respectively. Conclusions:The proposed markless setup workflow based on AlignRT combined with open-face mask immobilization for whole-course head tumor radiotherapy exhibits reasonable agreement and consistency with the patient setup using CBCT, with acceptable clinical efficiency. It can be applied to the first radiotherapy and the real-time monitoring of therapy to improve the safety and thus is of value in clinical applications.

Objective: To explore the relationships between the characteristics of childhood sexual abuse and non-suicidal self-injury in nursing female college students. Methods: Two medical colleges and junior colleges were selected in Anhui province. A total of 2 549 female nursing students in grade 1 to 3 were asked to fill a questionnaire regarding sociodemographic information,childhood sexual abuse and non-suicidal self-injury. Results: The reported rate of non-suicidal self-injury among female nursing students in the past six months was 8.2%. Sexual abuse at any time during childhood (primary school or earlier,middle school and high school) increased the risk of non-suicidal self-injury among female nursing students (P<0.05). Exposure to sexual abuse in all three periods was associated with 5.04(95%CI=1.73-14.62) times odds ratio than that of those who not exposed to sexual abuse (P<0.01). Only contact sexual abuse and both contact and non-contact sexual abuse in childhood were correlated with nonsuicidal selfinjury among female nursing students [OR(95%CI)=2.21(1.48-3.29), 3.56(2.13-5.96)] (P<0.05). Two patterns of sexual abuse experiences were identified,including persistent sexual abuse (3.1%) and the other group is occasional sexual (96.9%). Persistent sexual abuse in childhood was correlated to higher risk of non-suicidal self-injury compared with occasional sexual abuse (OR=2.61,95%CI=1.35-5.05,P<0.01). Conclusion The occurrence periods,types and patterns of sexual abuse in childhood are closely related to non-suicidal self-injury in female nursing students.

The pathogenesis of diabetic retinopathy (DR) is complex.Antisense non-coding RNA (ANRIL) in the INK4 locus in long-chain non-coding RNA (lncRNA) is closely related to cell proliferation,differentiation,and individual development.It plays an important role in the dysplasia of retinal vascular endothelial cells and is a new field in the study of the pathogenesis of DR.According to the researches at present,ANRIL may plays its role in the occurrence and development of DR through the signal pathway of nuclear factor-κB and ROS/polyadenylation diphosphate ribose polymerase,and interact with p300,miR-200b,and EZH2 to regulating the expression and function of VEGF.Specific blocking ANRIL and its related pathwaysmay become a new target in the treatment of DR.
