Objective To explore the risk factors for postoperative respiratory failure (RF) in patients with esophageal cancer, construct a predictive model based on the least absolute shrinkage and selection operator (LASSO)-logistic regression, and visualize the constructed model. Methods A retrospective analysis was conducted on patients with esophageal cancer who underwent surgical treatment in the Department of Thoracic Surgery, Sun Yat-sen University Cancer Center Gansu Hospital from 2020 to 2023. Patients were divided into a RF group and a non-RF (NRF) group according to whether RF occurred after surgery. Clinical data of the two groups were collected, and LASSO-logistic regression was used to optimize feature selection and construct the predictive model. The model was internally validated by repeated sampling 1000 times based on the Bootstrap method. Results A total of 217 patients were included, among which 24 were in the RF group, including 22 males and 2 females, with an average age of (63.33±9.10) years; 193 were in the NRF group, including 161 males and 32 females, with an average age of (62.14±8.44) years. LASSO-logistic regression analysis showed that the percentage of forced expiratory volume in one second/forced vital capacity (FEV1/FVC) to predicted value (FEV1/FVC%pred) [OR=0.944, 95%CI (0.897, 0.993), P=0.026], postoperative anastomotic fistula [OR=4.106, 95%CI (1.457, 11.575), P=0.008], and postoperative lung infection [OR=3.776, 95%CI (1.373, 10.388), P=0.010] were risk factors for postoperative RF in patients with esophageal cancer. Based on the above risk factors, a predictive model was constructed, with an area under the receiver operating characteristic curve of 0.819 [95%CI (0.737, 0.901)]. The Hosmer-Lemeshow test for the calibration curve showed that the model had good goodness of fit (P=0.527). The decision curve showed that the model had good clinical net benefit when the threshold probability was between 5% and 50%. Conclusion FEV1/FVC%pred, postoperative anastomotic fistula, and postoperative lung infection are risk factors for postoperative RF in patients with esophageal cancer. The predictive model constructed based on LASSO-logistic regression analysis is expected to help medical staff screen high-risk patients for early individualized intervention.

Objective To evaluate the safety and feasibility of remote robot-assisted thoracoscopic surgery utilizing 5G technology. Methods Clinical data from five patients who underwent 5G remote robot-assisted thoracoscopic surgery at the Thoracic Surgery Center of Gansu Provincial People's Hospital from May to October 2024 were retrospectively analyzed. Results Finally, five patients were included. There were 2 males and 3 females at median age of 50 (42-63) years. All five surgeries (including 1 patient of lobectomy, 3 patients of partial lung resection and 1 patient of mediastinal lesion resection) were successfully completed without conversion to thoracotomy, complications, or mortality. The median intraoperative signal delay across the patients was 39 (37-42) ms. The median psychological load score for the surgeons was 9 (3-13). The median operation time was 100 (80-122) minutes with a median intraoperative blood loss of 100 (30-200) mL. Catheter drainage lasted a median of 4 (3-5) days, and the median drainage volumes on the first, second, and third postoperative day were 200 (100-300) mL, 150 (60-220) mL, and 80 (30-180) mL, respectively. The median postoperative hospital stay was 4 (3-7) days, and the median pain scores on the third postoperative day were 3 (1-4), 3 (0-3), and 1 (0-3), respectively. Conclusion 5G remote robot-assisted thoracoscopic surgery is safe and effective, with good surgical experience, smooth operation and small intraoperative delay.

OBJECTIVE To analyze chemical components of Yao ethnic medicine Pittosporum pauciflorum， establish its fingerprint and investigate the spectrum-effect relationship of its anti-inflammatory effect. METHODS UHPLC-Q-Orbitrap-MS technology was used to analyze the chemical components of P. pauciflorum （batch S6）. The fingerprints for 10 batches of P. pauciflorum from different producing areas in Guangxi Province （batches S1-S10） were established by HPLC， and similarity assessment and chemometric pattern recognition analysis were conducted. RAW264.7 inflammatory cell model was induced by lipopolysaccharide， and the anti-inflammatory activity of P. pauciflorum was investigated. Using inhibition rates of nitric oxide （NO）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-1β as efficacy indicators， grey relational analysis and partial least squares regression analysis were adopted to evaluate the spectrum-effect relationship of the anti-inflammatory effect of P. pauciflorum. RESULTS There were 60 chemical components， including flavonoids， phenolic acids， lipids， etc.， identified in P. pauciflorum. The fingerprints for 10 batches of P. pauciflorum showed 14 common peaks，with similarity values ranging from 0.883 to 0.991. Three common peaks were assigned neochlorogenic acid （peak 5）， chlorogenic acid （peak 7）， and syringaldehyde （peak 10）. The classification results of the systematic clustering analysis and the principal component analysis were basically consistent. Batches S1 to S10 of P. pauciflorum significantly reduced the levels of NO， TNF-α， IL-6 （except for batch S5） and IL-1β in the cell supernatant （P＜0.05 or P＜0.01）. Inhibition rates of above inflammatory indexes were 10.26%-39.96%， 14.96%-31.36%， 1.38%-21.27%， 18.54%-28.00%， respectively. The contents of neochlorogenic acid， syringaldehyde， as well as the components corresponding to peaks 1， 3， 9， 12 and 14，exhibited a strong correlation with the anti-inflammatory effects of P. pauciflorum. CONCLUSIONS The present study has analyzed the chemical components of P. pauciflorum and established HPLC fingerprints for 10 batches of P. pauciflorum. Each batch of medicinal herbs demonstrates certain anti- inflammatory activities， among which neochlorogenic acid， syringaldehyde， and the components corresponding to peaks 1， 3， 9， 12 and 14 are likely to be the active anti-inflammatory components.

OBJECTIVE To explore comprehensive management and potential issues associated with long-term prescriptions medications of psychiatry， in order to provide a reference for the comprehensive management of long-term prescriptions of psychiatry in psychiatric hospitals and other medical institutions’ pharmacies. METHODS Starting from the applicable principles for long-term prescriptions of psychiatry， this study introduced the standardized assessment and precautions before issuing long-term prescriptions， the formulation and adjustment of the drug list， as well as the rational management of the long-term prescriptions. It also analyzed potential issues that may arise in the comprehensive management of long-term prescription medications and proposed corresponding countermeasures and suggestions. RESULTS & CONCLUSIONS Prior to initiating long-term prescriptions， a standardized assessment should be conducted on patients from the aspects of their psychiatric condition and long-term potential risk factors， pharmacological treatment plans and other non-pharmacological therapies， physical illnesses. Additionally， healthcare providers should fulfill their obligation to inform patients or their family members. The comprehensive management of long-term prescription medications should be jointly established and improved by multiple departments， and the formulation of drug catalogs should avoid including drugs with potential social harm or medication risks while complying with policy requirements. Furthermore， measures such as adding special identifiers to long-term prescriptions， providing patients with reminders about （No.YGLX202537） prescription expiration， or offering online consultations can also effectively enhance the rationality of medication use under long-term prescriptions. Currently， the implementation of long-term prescriptions in psychiatry remains challenged by inconsistencies in prescription duration， incomplete coverage of diagnostic categories， poor patient adherence， and the risk of deviation in clinical assessments. In this regard， measures such as collaborating with multiple departments to strengthen long-term prescription information management， providing matching pharmaceutical services， ensuring the quality and rationality of long-term prescription implementation， and using modern methods to screen high-risk patients can be taken to improve patient medication compliance and safety.

Objective:To evaluate the clinical efficacy of Cai's gynecological nourishing kidney therapy for patients with diminished ovarian reserve (DOR).Methods:A randomly controlled trail was conducted. A total of 63 patients with DOR who were treated in the gynecology outpatient clinic of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine from September 2020 to January 2022 were set as observation subjects, and were divided into control group ( n=31) and observation group ( n=32) according to the random number table method. The patients in the control group were treated with Femoston, and the patients in the observation group were treated with Cai's gynecological nourishing kidney therapy on the basis of Femoston treatment. Both groups were treated for 3 menstrual cycles. Both antral follicle count (AFC) was performed by vaginal ultrasound, serum levels of TGF-β1, IL-1β, IL-2, IL-6 and IL-21 were detected by ELISA, and serum levels of FSH, LH, E2, anti-Müllerian hormone (AMH) and MDA were detected by biochemical methods. The TCM syndrome score was used to evaluate the severity of symptoms, and the menstrual score was used to evaluate the abnormal menstruation. Clinical efficacy was evaluated. Results:The total effective rate was 87.50% (28/32) in the observation group and 58.06% (18/31) in the control group, with statistical significance ( χ2=8.42, P=0.004). After treatment, the AFC in the observation group (3.93±2.32 vs. 2.21±2.18, t=3.03) was higher than that of the control group ( P<0.01). After treatment, the serum FSH level of the observation group [10.05 (8.35, 21.48) IU/L vs. 20.60 (8.00, 43.30) IU/L, Z=2.18] was lower than that of the control group ( P<0.05), and the level of AMH [0.19 (0.03, 0.47) μg/L vs. 0.02 (0.01, 0.24) μg/L, Z=-1.54] in the observation group was higher than that of the control group ( P<0.05). The serum levels of TGF-β1 [(68.27±11.76) ng/L vs. (55.33±13.03) ng/L, t=4.14] and IL-1β [(58.00±7.53) ng/L vs. (52.31±8.06) ng/L, t=2.89] in the observation group were higher than those in the control group, and the levels of IL-6 [(33.26±7.45) ng/L vs. (40.69±11.69) ng/L, t=3.02], the level of IL-21 [(118.37±15.56) ng/L vs. (140.43±25.51) ng/L, t=-4.04] was lower than that of the control group ( P<0.01). Conclusions:Cai's gynecological nourishing kidney therapy combined with Fenmaotong can effectively increase the AFC of DOR patients and improve clinical efficacy. Its mechanism of action may be related to reducing serum FSH and LH levels and increasing E2 levels.

Purpose To construct a benign and malignant prediction model of thyroid nodules based on ultrasound image features and clinical features,and to evaluate its diagnostic efficacy.Materials and Methods The data of 121 patients diagnosed with thyroid nodules admitted to the General Hospital of Northern Theater Command from September 2020 to March 2022 were retrospectively analyzed.Taken surgical pathology as the gold standard,there were 70 benign nodules and 51 malignant nodules.Logistic regression was used to analyze the ultrasound image characteristics and clinical data of thyroid nodules,and the characteristic indexes with statistical differences were obtained and a comprehensive prediction model was established.Results There were significant differences in the maximum diameter,morphology,calcification,capsule continuity,blood flow grade,elastography score and contrast-enhanced ultrasound characteristics between benign and malignant thyroid nodules(χ2=11.709,17.707,6.901,12.785,16.984,57.095,98.854,all P<0.05).There were significant differences in age,free thyroxine/free thyroxine ratio,and free thyroxine between the two groups(χ2/t=5.944,2.519,-2.468,all P<0.05).The sensitivity,specificity and accuracy of the clinical model,ultrasonic characteristic model and ultrasonic-clinical combined model were 55.7%,98.6%and 97.0%;72.5%,94.1%and 96.1%;and 61.9%,95.1%and 95.9%,respectively.The area under the curve of the three models were 0.619,0.991 and 0.994,respectively.The diagnostic efficiency of the ultrasonic characteristic model and the combined model was superior to the clinical model,and the difference was statistically significant(Z=-1.75,-2.25,P=0.039,0.012).The area under the curve of the combined model was greater than that of the multi-modal ultrasound model,however,the difference was not statistically significant(Z=-1.60,P=0.054).Conclusion Both the multimodal ultrasound model and the clinical model have certain diagnostic value in predicting benign and malignant thyroid nodules.The diagnostic efficiency of the multimodal ultrasound model is higher than that of the clinical model,and the combined prediction model of the two can improve the diagnostic value.

Objective:To review the clinical status based on the best evidence of drug administration in patients with dysphagia, systematically analyze the obstacle factors and promoting factors in the process of evidence transformation, and formulate reform strategies.Methods:Based on the evidence-based nursing research method and the guidance of the Ottawa Model of Research Use (OMRU), the review indicators were developed based on the best evidence. The current status of clinical practice behaviors of 223 patients and 75 nurses in the Neurology, Neurosurgery and Geriatric departments of the Affiliated Hospital of Jiangsu University were reviewed from July to December 2021.Based on the results of the review, qualitative interviews were conducted with 32 potential adopters, and content analysis was used to assess the barriers and contributing factors to the clinical translation of evidence in three aspects: evidence-based change, potential adopters and practice environment, so as to develop effective strategies.Results:Based on the 22 best evidence selected, the evidence-based team developed 25 review indicators to carry out clinical review, showing that the compliance rate of 16 indicators were less than 60%. By analyzing and summarizing the interview results of potential adopters, the main obstacles leading to the low compliance rate of nurses were analyzed as follows: evidence-based reform changed the traditional work mode, and the application of evidence was not convenient; at the level of potential adopters, nurses had poor knowledge and practice, heavy work burden, and low awareness of patients and caregivers; at the level of practice environment, there was lack of nursing norms and procedures for clinical transformation of evidence, and the channels of multi-disciplinary collaboration and communication were not smooth. The main promoting factors were the perfect supervision mechanism of evidence-based nursing projects, the evidence-based group had rich experience in evidence transformation, the management was willing to change, and the practitioners were good at innovation.Conclusions:There is still a large gap between the clinical practice and the best evidence of drug administration in patients with dysphagia. The promoting factors should be fully utilized to overcome the obstacles and implement improvements to promote the effective transformation of evidence into clinical practice.

Neck dissection and reconstruction are two important aspects of oral cancer treatment.There are various surgical methods for neck dissection and reconstruction,but all of them are performed by open surgery.This article reports a full endoscopic neck dis-section through the retroauricular hairline approach,the radical resection of the intraoral tumor and the repair of the defect by superfi-cial circumflex iliac artery perforator flap with in situ vascular anastomosis intraorally.The incision is located in the hairline,hidden and invisible,and there is no exposed surgical scar on the neck after surgery.This paper introduces the technique of scarless neck dissection combined with free skin flap repair for the treatment of oral cancer and discusses its advantages and disadvantages.

Objective:To observe the effect of Nodal on the biological behavior of retinal vascular endothelial cells (RF/6A cells) in monkeys with high glucose.Methods:RF/6A cells were divided into normal group, mannitol group, high glucose group, high glucose combined with non-specific small interfering RNA treatment group (HG+NC group), high glucose combined with small interfering Nodal treatment group (HG+siNodal group). The transfection efficiency of siNodal was observed by real-time fluorescence quantitative PCR and western blot protein immunoblotting. The effect of Nodal on the proliferation of RF/6A cells was detected by thiazole blue colorimetry. The effect of Nodal on migration ability of RF/6A cells was detected by cell scratch assay. The effect of Nodal on the formation of RF/6A cell lumen was measured by Matrigel three-dimensional in vitro. The expression of extracellular signal phosphorylated regulated kinase 1/2 (pERK1/2) in RF/6A cells was detected by western blot protein immunoblotting. One-way analysis of variance was used to compare groups.Results:Compared with HG+NC group, Nodal protein ( F=33.469) and mRNA relative expression levels ( F=38.191) in HG+siNodal group were significantly decreased, cell proliferation was significantly decreased ( F=28.548), and cell migration ability was significantly decreased ( F=24.182). The number of cell lumen formation was significantly decreased ( F=52.643), and the differences were statistically significant ( P<0.05). Compared with HG+NC group, the relative expression of pERK1/2 protein in HG+siNodal group was significantly decreased, and the difference was statistically significant ( F=44.462, P<0.01). Conclusions:Silencing Nodal expression can inhibit proliferation, migration and tube formation of RF/6A cells induced by high glucose. It may act by inhibiting pERK1/2 expression.

OBJECTIVE To investigate the effects and mechanism of polysaccharides from Hedyotis diffusa （HDP） on isoniazid （INH）-induced liver injury. METHODS Healthy transgenic zebrafish with liver-specific fluorescence were divided into normal group， model group （4 mmol/L INH）， HDP low-concentration group （4 mmol/L INH+50 mg/mL HDP） and HDP high- concentration group （4 mmol/L INH+100 mg/mL HDP）. After grouping treating， the liver fluorescence area， fluorescence intensity and pathological changes of liver tissue were observed. Human liver L02 cells were divided into normal group， model group （4 mmol/L INH）， HDP low-concentration group （4 mmol/L INH+2 mg/mL HDP）， and HDP high-concentration group （4 mmol/L INH + 4 mg/mL HDP）. After grouping treating， the cell viability was detected， and the levels of alanine transaminase （ALT）， aspartate transaminase （AST）， and the content of glutathione （GSH） as well as the expression levels of silent information regulator 1 （Sirt1）， nuclear factor-erythroid 2-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1） and quinone oxidoreductase 1 （NQO1） proteins were detected. RESULTS Compared with the model group， the HDP low- and high-concentration groups showed varying degrees of increase in the fluorescence area and fluorescence intensity （except for HDP low-concentration group） of zebrafish liver （P＜0.05 or P＜0.01）， and the characteristics of liver injury and necrosis had been improved to varying degrees. Compared with model group， the survival rate of L02 cells， the content of GSH （except for HDP low-concentration group）， the protein expression levels of Sirt1 （except for HDP low-concentration group）， Nrf2， NQO1， HO-1 （except for HDP low-concentration group） were significantly increased in HDP low- and high-concentration groups （P＜0.05 or P＜0.01）， and the levels of ALT and AST （except for HDP low-concentration group） were significantly decreased （P＜0.05）； the number of survival cells significantly increased， while the number of damaged or dead cells significantly decreased. CONCLUSIONS HDP has a potential protective effect against INH-induced liver injury， the mechanism of which may be associated with activating Sirt1/Nrf2 signaling pathway， improving mitochondrial function and enhancing antioxidant capacity.
