Objective:To build a nursing care plan decision-making support system based on the hospital's nursing information system and evaluate its effects in newly hired nurses.Methods:This study adopted a non-synchronous pre-post control design. Totally 181 newly hired nurses recruited by Beijing Tiantan Hospital, Capital Medical University, were selected by convenience sampling. The control group consisted of 85 new nurses hired in August 2021, while the intervention group consisted of 96 new nurses hired in August 2022. The control group received traditional training methods, while the intervention group received training through the nursing care plan decision-making support system in addition to the traditional methods. The nursing decision-making ability and the quality of specialty nursing care were compared between the two groups.Results:Finally, 81 nurses were included in the control group, and 93 nurses were included in the intervention group. The nursing decision-making ability score in the intervention group was (80.15±4.59), which was significantly higher than the (78.62±5.13) in the control group ( t=-2.080, P=0.039). The intervention group also had a significantly higher qualified rate of specialty nursing care compared to the control group (χ 2=6.626, P=0.036) . Conclusions:The application of the nursing care plan decision-making support system in the standardized training of newly hired nurses can improve their nursing decision-making abilities and the quality of specialty nursing care.

Objective: To establish a nomograph model for prediction of cervical central lymph node metastasis (CLNM) among patients with thyroid papillary carcinoma (PTC), so as to provide the evidence for designing personalized treatment plans for PTC. Methods : The data of patients that underwent thyroidectomy and were pathologically diagnosed with PTC post-surgery in the Affiliated Traditional Chinese Medicine Hospital of Xinjiang Medical University from 2018 to 2021 were collected. Patients' data captured from 2018 to 2020 and from 2021 were used as the training set and the validation set, respectively. Predictive factors were screened using a multivariable logistic regression model, and the nomograph model for prediction of CLNM risk was established. The predictive value of the model was evaluated using the receiver operating characteristic (ROC) curve and the adjusted curve. Results: Totally 1 820 PTC cases were included in the training set, including 458 cases with CLNM (25.16%), and 797 cases in the validation set, including 207 cases with CLNM (25.98%). The prediction model is p=ey/(1+ey), y=0.761 + 0.525 × sex + (-0.039) ×age + 0.351 × extrathyroid invasion + 0.368 × neck lymph node enlargement + 1.021×maximum tumor diameter + (-0.009) × TT4 + (-0.001) × anti-TPOAb. The area under the ROC curve was 0.732 for the training set and 0.731 for the validation set, and Hosmer-Lemeshow test showed a good fitting effect (P=0.936, 0.722). Conclusion The nomograph model constructed in this study has a high predictive value for CLNM among patients with PTC.

Objective:To investigate the current situation of supportive care needs for patients with glioma after surgery and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 168 postoperative patients with glioblastoma admitted to Beijing Tiantan Hospital Affiliated with Capital Medical University from January to May 2022 were selected as the research objects. The general information questionnaire, Supportive Care Need Survey-34-item Short Form (SCNS-SF34), M.D.Anderson Symptom Inventory Brain Tumor Module (MDASI-BT) and Cancer Fatigue Scale (CFS) were used to investigate them. The multiple linear regression analysis was used to explore the influencing factors of supportive care needs in patients with glioma after surgery.Results:The score for supportive care needs in 168 postoperative patients with glioblastoma was (71.68±25.28). The results of multiple linear regression analysis showed that place of residence, occupational status, degree of symptom distress and fatigue degree were the influencing factors for supportive care needs of glioma patients after surgery ( P<0.05) . Conclusions:Patients with glioma after surgery have unmet supportive care needs, which are influenced by their place of residence, work status, disease symptoms and fatigue levels. Medical staff provide personalized guidance to postoperative patients to help them cope with postoperative symptoms, reduce fatigue levels and meet their supportive care needs.

OBJECTIVE To study the absorption characteristics of phenylpropanoids of Mongolian medicine Tabson-2 decoction(TBD) in Caco-2 cells and to preliminarily clarify the oral absorption mechanism of TBD. METHODS Caco-2 cell monolayer model was used to analyze the uptake components of TBD in Caco-2 cells by UPLC-MS/MS, and UPLC-MS/MS analysis method was established to determine the nine best absorbed components of TBD, protocatechuic acid, neochlorogenic acid, chlorogenic acid, cryptogenic acid, 1,5-dicaffeinate quinic acid, isochlorogenic acid C, caffeic acid, dihydrocaffeic acid, chlorogenic acid. The effects of time, concentration and P-glycoprotein inhibitor on the absorption of each component were investigated. RESULTS The overall intake of caffeic acid and dihydrocaffeic acid showed an upward trend in 0-180 min, and did not show saturation. The absorption of 3-hydroxycinnamic acid was constant at about 90 min and tended to saturation. The intakes of cryptochlorogenic acid, 1,5-dicaffeinate, quinic acid, isochlorogenic acid C, neochlorogenic acid, chlorogenic acid and protocatechuic acid first decreased and then increased with time from about 90 min. The addition of P-glycoprotein inhibitor verapamil and cyclosporin A had an effect on the absorption of dihydrocaffeic acid compared with the phenylpropanoid components, indicated that dihydrocaffeic acid was the substrate of P-glycoprotein. CONCLUSION The main phenylpropanoids of TBD enter Caco-2 mainly by passive diffusion, supplemented by active transport, and the absorption process of the other eight components is not affected by the efflux of P-glycoprotein except dihydrocaffeic acid.

Objective:To understand the reinfection rate of 2019-nCoV in the previously infected population in Suzhou and compare the illness severity and prognosis of the reinfection cases with the first-time infection cases.Methods:A questionnaire survey was conducted in the persons with previous 2019-nCoV infection reported in Suzhou from January 22, 2020 to November 8, 2022 to collect the information about the incidence of reinfection of 2019-nCoV in this population from December 8, 2022 to January 18, 2023. The persons who were infected with 2019-nCoV for the first time were selected by marching the residence, age and gender at ratio of 1∶2 from 2019-nCoV infection community follow-up cohort of Suzhou. By χ2 test, the clinical symptoms and prognosis of the reinfection case and the first-time infection cases were compared. Results:The reinfection rate of 2019-nCoV was 13.01% (147/1 130) in Suzhou. No reinfection was found within 1-6 months after the first-time infection, the rate of reinfection was 10.59% (95/897) in those with interval of 7-12 months between the reinfection and the first-time infection and 45.61% (52/114) in those with the interval ≥24 months. The lowest reinfection rate was 9.09% (1/11) in those who had completed 4 doses of 2019-nCoV vaccination. The main symptoms of the reinfection cases were similar to those of the first-time infection cases. Except for dry cough, nausea/poor appetite and other symptoms, there were significant differences in other clinical symptoms between the two groups ( P<0.05). In the reinfection cases, fever had shorter duration with lower body temperature. The hospital visit rate in the reinfection cases was 4.08% (6/147), lower than that in the cases with the first-time infection (11.56%, 34/294). The time for negative nucleic acid (antigen) test result and recovery from illness after the reinfection were shorter than those after the first-time infection. Conclusions:Reinfection occurred in some people who had been infected with 2019-nCoV. The interval between the reinfection and the first-time infection and the completion of the 4 doses of booster vaccination were the factors influencing the reinfection rate. The hospital visit rate in the reinfection cases was lower than that in the cases with the first-time infection. The reinfection had similar symptoms and shorter illness duration compared with the first-time infection.

Objective:To investigate the effect of cold compress of cooling paste on postoperative nasal symptoms of patients undergoing neuroendoscopic transsphenoidal approach surgery.Methods:From June 2019 to June 2020, the convenient sampling method was used to select 86 patients undergoing neuroendoscopic transsphenoidal approach surgery who were hospitalized in the Third Ward of Department of Neurosurgical Oncology in Beijing Tiantan Hospital affiliated to Capital Medical University as the research objects. The patients were divided into the control group and the observation group by the random block method, with 43 cases in each group. The control group was given routine perioperative nursing care. The patients in the experimental group were given cooling paste cold compress on the nose after operation. First, the patients' nasal skin was cleaned, and the refrigerated cooling paste was applied on both sides of the patient's nose alar to the root of the nose and replaced every 8 hours for 7 consecutive days. If it fell off, it was subsidized immediately. The Sino-Nasal Outcome Test-22 (SNOT-22) and General Comfort Questionnaire (GCQ) were used to compare the nasal and sinus outcomes and comfort of the two groups before surgery, 24 hours after surgery and 7 days after surgery.Results:The total score of SNOT-22, physiological function, emotional outcome and functional limitation scores of patients in the observation group were lower than those in the control group at 24 h after operation, and the differences were statistically significant ( P<0.05) . The total score of SNOT-22, emotional outcome and functional limitation score of the observation group 7 days after operation were lower than those of the control group, and the differences were statistically significant ( P<0.05) . The comfort score of the observation group at 24 hours after operation was higher than that of the control group, and the difference was statistically significant ( P<0.05) . But there was no statistically significant difference in the comfort score between the two groups at 7 days after operation ( P>0.05) . Conclusions:Cold compress of cooling paste can effectively improve the nasal cavity and sinus outcomes and comfort of 24 hours after neuroendoscopic transsphenoidal approach surgery.

Objective:To understand the psychosomatic experience and needs of patients with lumbar cistern drainage after transnasal endoscopic sinus surgery in neurosurgery while lying in bed.Methods:Using the purposeful sampling method, one-to-on, face-to-face semi-structured interviews were conducted among 12 patients with lumbar cistern catheter drainage who were treated in Beijing Tiantan Hospital Affiliated to Capital Medical University from July to August 2020.

To establish a method for the determination of formaldehyde and glyoxal simultaneously in varenicline tartrate active pharmaceutical ingredient (API) and its intermediate, formaldehyde and glyoxal were derivatized by 2, 4-dinitrophenylhydrazine (2,4-DNPH) to improve the HPLC retention and UV detection sensitivity. Separation was performed on a C8 (150 mm × 4.6 mm, 5 μm) column by linear gradient elution using acetonitrile and water as the mobile phase; the detective wavelength was set at 380 nm.Formaldehyde and glyoxal were quantitatively determined by an external reference method.Linear calibration was established for both formaldehyde and glyoxal in the range from 0.094 to 1.88 μg/mL.The detection and the quantification limits were 0.047 μg/mL (19 μg/g) and 0.094 μg/mL (38 μg/g), respectively.The recoveries were (95.0±1.1)% and (99.4 ± 2.6)% for formaldehyde and glyoxal, respectively.This method has been fully validated to be applicable to quantitative analysis of trace amount of formaldehyde and glyoxal in varenicline tartrate API and its intermediate.Test results demonstrated that the contents of both formaldehyde and glyoxal met the permitted daily exposure (PDE) limits for the finished products of varenicline tartrate API as well as its intermediate, though the glyoxal contents in the crude intermediates were likely to exceed the limit.The established method is valuable for the manufacturing process and quality control of varenicline tartrate.

This study aimed to identify the related substances of lorazepam tablets by liquid chromatography mass spectrometry (LC-MS). To separate the related substances of lorazepam tablets, gradient elution was performed using acetonitrile and 0.1% acetic acid -20 mmol/L of ammonium acetate as mobile phase on Inert Sustain C18 (250 mm × 4.6 mm, 5 μm).The accurate mass and elemental composition of the parent ions and their product ions of related substances were determined by electrospray-ionization quadrupole time-of-flight high resolution mass spectrometry (ESI-Q-TOF/MS).The structures of the related substances were identified by spectral analysis. Under the established analytical condition, lorazepam and its related substances were adequately separated, and 22 major related substances with content greater than 0.1% were detected and identified by hyphenated techniques in lorazepam tablets and their stressed samples.Among them, 5 were the impurities listed in the USP or EP, and the others were unknown related substances identified for the first time in this paper.The LC-MS technique can effectively separate and identify the related substances of lorazepam tablets, which provides some reference for quality control.
