ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective To identify the independent predictors of programmed death-1 (PD-1) inhibitor-related endocrine adverse events and construct a clinically usable risk prediction model. Methods A total of 302 patients with solid tumors treated with PD-1 inhibitors were retrospectively enrolled. According to the presence or absence of endocrine immune-related adverse events (irAEs), the patients were divided into case group and control group. The clinical and laboratory indexes were compared between the two groups. Multivariable logistic regression was used to confirm independent predictors of endocrine irAEs. The nomogram was constructed, while the receiver operating characteristic (ROC) curve was used to test the prediction performance of the model. Results The overall incidence of endocrine irAEs was 21.9% (66/302), and the incidence of hypothyroidism was 19.5% (59/302). The age, PD-1 inhibitors, free thyroxine, thyroid peroxidase antibody (TPOAb), thyroglobulin, amylase, lymphocyte subset CD3 expression were statistically different between the two groups (P＜0.05). Multivariable logistic regression showed that higher expression of lymphocyte subset CD3 was a protective factor to prevent endocrine irAEs occurrence (P＝0.004), while age＜60 years, higher TPOAb and use of pembrolizumab were independent risk factors of endocrine irAEs (P＜0.05). The nomogram model thus constructed, and when the threshold probability of the model exceeded 0.1, its net benefit was higher. ROC curve showed that the AUC of the model to predict endocrine irAEs was 0.760. The prediction result of the model was highly consistent with the actual result. Conclusions The age, type of PD-1 inhibitor, baseline TPOAb level, and baseline CD3 expression can independently predict endocrine irAEs occurrence or not. The nomogram model based on this model has good predictive efficiency, which can provide reference for early identification of high-risk patients and immunotherapy management.

Objective To evaluate the relationship between diabetic nephropathy(DN)and diabetic retinopathy(DR)in patients with type 2 diabetes mellitus(T2DM)based on imaging and clinical testing data.Methods Totally 600 T2DM patients who visited the First People's Hospital of Ziyang from March 2021 to December 2022 were included.The fundus photography and fundus fluorescein angiography were performed on all these patients and their age,gender,T2DM duration,cardiovascular diseases,cerebrovascular disease,hypertension,smoking history,drinking history,body mass in-dex,systolic blood pressure,diastolic blood pressure and other clinical data were collected.The levels of fasting blood glu-cose(FPG),triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipo-protein cholesterol(LDL-C),glycosylated hemoglobin(HbA1c),24 h urinary albumin(UAlb),urinary albumin to creati-nine ratio(ACR),serum creatinine(Scr)and blood urea nitrogen(BUN)were measured.Logistic regression was used to analyze the risk factors associated with DR.DR staging was performed according to fundus images,and the convolutional neural network(CNN)algorithm was used as an image analysis method to explore the correlation between DR and DN based on emission computed tomography(ECT)and clinical testing data.Results The average lesion area rates of DR and DN detected by the CNN in the non-DR,mild-non-proliferative DR(NPDR),moderate-NPDR,severe-NPDR and pro-liferative DR(PDR)groups were higher than those obtained by the traditional algorithm(TCM).As DR worsened,the Scr,BUN,24 h UAlb and ACR gradually increased.Besides,the incidence of DN in the non-DR,mild-NPDR,moderate-NPDR,severe-NPDR and PDR groups was 1.67％,8.83％,16.16％,22.16％and 30.83％,respectively.Logistic regression analysis showed that the duration of T2DM,smoking history,HbA1c,TC,TG,HDL-C,LDL-C,24 h UAlb,Scr,BUN,ACR and glomerular filtration rate(GFR)were independent risk factors for DR.Renal dynamic ECT analysis demonstrated that with the aggravation of DR,renal blood flow perfusion gradually decreased,resulting in diminished renal filtration.Conclusion The application of CCN in the early stage DR and DN image analysis of T2DM patients will improve the diag-nosis accuracy of DR and DN lesion area.The DN is worsening as the aggravation of DR.

Male overseas labor export personnel aged 20 to <50 were the key demographic.

Objective To explore the nutritional efficacy of compound protein powder formulations from different sources. Methods Three groups of compound protein powder formulations were obtained through scientific blending using soy protein, whey protein and yeast protein as raw materials. The effects of the compound protein powders on nitrogen metabolism, serum biochemical indicators, and pathological changes of liver tissue and epididymal fat in rats were evaluated. Results Compared with the control (casein), the net protein utilization, biological evaluation, and protein efficacy ratio of the compound protein powders in rats were significantly improved, and the changes in these indicators in the formula with the highest whey protein content were most significant among all three formulas. The compound protein powders effectively increased the levels of albumin and globulin, while decreased the content of total cholesterol, indicating beneficial effects on improving immunity and controlling lipid metabolism, with the formula group 2 being the most effective among all three groups. The pathological examination showed that the three groups of protein powder did not have adverse effects on liver tissue and epididymal fat. Conclusion The present study demonstrates that the compound protein powder formulation has nutritional value, which suggests a potential of the application of the compound protein powder formulation in the elderly, and people with special nutritional needs, such as sports people.

Objective:To standardize the naming of organ at risk (OAR) and target area during cervical cancer radiotherapy based on AAPM TG-263.Methods:After self-programming of Matlab software to implement the reading and resolution of radiotherapy structure files, the naming of each substructure was automatically output, recorded and restored. After naming all substructures, the structure names were classified by keywords. According to TG-263, a standard naming conversion table of OAR and target area was developed, and the classified structure names were standardized through procedures. Finally, the standardized named radiotherapy structure files were output and imported into the treatment planning system (TPS).Results:The radiation structure of 144 patients with cervical cancer was successfully transformed and displayed correctly in TPS. Before the transformation, the naming of OAR and target area lacked of uniform norms and standards, and the naming of the same structure significantly differed. After the transformation, 43 naming methods of OAR and 74 naming methods of the target area were unified into 20 and 8 naming methods, which were more convenient for staff understanding and communication.Conclusion:The standardization of cervical cancer radiotherapy structure naming can reduce the inconsistency of naming and provide reference for the standardized naming of pelvic tumors.

Objective:To evaluate the readiness for application of the Facilitating Client Centred Learning guideline among nurses in a general hospital and analyze its influencing factors. Methods:In December 2019, cluster sampling was used to select 138 nurses from 12 nursing units in a general hospital who intended to apply the guideline as research subjects. The Clinic Readiness of Evidence-Based Nursing Assessment (CREBNA) was used to evaluate the readiness of the guideline application, and the influencing factors were investigated and analyzed through the self-designed Influencing Factors Questionnaire. A total of 138 questionnaires were retrieved and 138 valid questionnaires were collected, with an effective rate of 100%.Results:Among 138 nurses, the score of CREBNA was (134.17±15.57) . The scores of the evidence subscale, organization environment subscale and promotion factor subscale were (51.35±6.22) , (39.85±5.00) and (42.97±5.88) respectively. Univariate analysis showed that the differences in the total score of CREBNA of nurses with different initial qualifications and whether they received evidence-based practice training were statistically significant ( P<0.05) . Multiple linear regression analysis showed that the influencing factors of nurses' readiness for evidence-based practice included the initial qualifications and whether they received evidence-based practice training with statistical differences ( P<0.05) . Conclusions:Nurses' readiness for evidence-based practice is affected by their initial qualifications and whether they have received evidence-based practice training. It is recommended that managers applying the guideline create an organizational environment that supports evidence-based practice, strengthen leadership in evidence-based practice, develop training programs suitable for different groups and various forms, and improve the knowledge, beliefs and skills of evidence-based practice for head nurses, guidance nurses and general nurses to lay a solid foundation for the smooth application of the guideline.

Objective To probe into the status and correlation between elder abuse tendency and psychological resilience of family caregivers of the elderly with chronic diseases. Methods Totally 402 family caregivers of the elderly with chronic diseases were investigated by the Chinese version of Caregiver Abuse Screening and Conner-Davidson Resilience Scale. Then the results underwent statistical analysis. Results Nearly 63.68%(256/402) family caregivers had the risk of elder abuse tendency. The median of family caregivers′resilience score was 53, lower than normal population(Z=-10.106, P=0.000), and was significantly negatively correlated with elder abuse tendency(r=-0.480, P=0.000).And caregivers′ high level of resilience was a protective factors for elder abuse tendency. Conclusions Nurses should motivate the family caregivers of the elderly with chronic diseases to adapt successfully when faced stress which could be associated with resilience. Thus the psychological resilience would play a role of protective effect against elder abuse tendency, with the purpose of reducing the risk for abusing the elderly who suffered from chronic diseases.
