Objective To investigate the value of thyroid hormone in predicting the prognosis of patients with chronic kidney disease(CKD)complicated with coronary heart disease.Methods The clinical data of 254 patients with coronary heart disease who underwent coronary angiography in the hospital directly under Hubei Province from January to December 2018 were analyzed.The serum levels of thyroid stimulating hormone(TSH),thyroxine(T4),free thyroxine(fT4),triiodothyronine(T3),free triiodothyronine(fT3)and thyroid-binding globulin(TBG)were measured by automatic chemiluminescence immunoassay.The estimated glo-merular filtration rate(eGFR)of each patient was calculated by the kidney disease formula.After the baseline survey,patients were followed until the end of the study or the end of the observation period.Multivariate Lo-gistic regression was used to analyze the influencing factors of CKD progression.Receiver operating character-istic(ROC)curve was used to analyze the value of serum T4,TBG levels and their combination in predicting the progression of CKD.Results Among the 254 patients enrolled,the incidence of renal function decline was 15.75%,and they were included in the progression group(n=40),and the rest were included in the non-pro-gression group(n=214).Compared with the non-progression group,the progression group had significantly lower levels of hemoglobin,T4,and TBG(P<0.05)and significantly higher levels of triglyceride,low-density lipoprotein,and proteinuria(P<0.05).Multivariate Logistic regression analysis showed that both serum T4 and TBG were risk factors for renal function decline in patients with CKD complicated with coronary heart disease(P<0.05).Compared with patients with eGFR≥90 mL/(min·1.73 m2),patients with eGFR<30,30-<60,60-<90 mL/(min·1.73 m2)had lower serum TBG levels(P<0.05).Patients with eGFR<30 mL/(min·1.73 m2)and 30-<60 mL/(min·1.73 m2)had lower serum T4 levels(P<0.05).Serum T4 and TBG levels were positively correlated with eGFR(r=0.178,0.300,P<0.01).The area under the curve of serum T4 combined with TBG for predicting CKD progression was 0.849(95%CI 0.800-0.899).Conclu-sion Low serum T4 and TBG levels are closely related to the progression of CKD in patients with CKD com-plicated with coronary heart disease.

Objective To establish a quality standard for the medicinal bath formula for treating exogenous fever(composed of Forsythiae Fructus,Peucedani Radix,Schizonepetae Spica,Isatidis Radix,Gypsum Fibrosum,Chrysanthemi Flos,Lophatheri Herba,etc.)based on its efficacy and indications.Methods Thin-layer chromatography(TLC)was used to establish identification method for the monarch drugs Forsythiae Fructus and Peucedani Radix.Enzyme-linked immunosorbent assay(ELISA)was employed to measure the interleukin 1β(IL-1β)regulatory activity of the main components in the formula.High-performance liquid chromatography(HPLC)was used to determine the content of active components in 10 batches of samples.Results Spots of Forsythiae Fructus and Peucedani Radix were successfully detected in the test samples.ELISA identified active components in the formula,including praeruptorin A,pulegone,rutin,praeruptorin B,forsythoside,and(R,S)-goitrin.The content determination results of 10 batches of samples showed that the content of praeruptorin A ranged from 0.493 to 0.694 mg·mL-1.Conclusion Based on its efficacy and indications,TLC identification and HPLC content determination methods were established for the medicinal bath formula for treating exogenous fever.The obtained standard can more accurately control the efficacy of the formula.

Objective To investigate the diagnostic value of electromyographic(EMG)tremor indicators for Parkinson's disease(PD)using the Logistic regression model.Methods A total of 65 patients with PD(PD group)and 39 patients with essential tremor(ET)(ET group)were enrolled and underwent EMG tremor analysis.General information,disease-related data,and EMG tremor characteristics were compared between the two groups.Multivariate Logistic regression analysis was performed to screen for independent influencing factors of PD,and receiver operating characteristic(ROC)curves were plotted.The area under the curve(AUC)was used to evaluate the diagnostic value of EMG tremor indicators for PD.Results Compared with the ET group,the PD group had a higher proportion of patients with unilateral onset and those with tremor spectrum frequency≥2 times,and a lower proportion of patients with a family history of tremor(P＜0.05).The tremor peak frequencies in the resting,postural,and weight-bearing(1 000 g)states were lower in the PD group than in the ET group(P＜0.05).There were statistically significant differences in the tremor rhythm patterns between the two groups in the resting and weight-bearing states(P＜0.05),with the PD group dominated by alternating contraction patterns and the ET group by synchronous contraction pat-terns.Multivariate Logistic regression analysis revealed that the tremor peak frequency in the weight-bearing state,the tremor rhythm pattern in the resting state,and the frequency of tremor spectrum were independent influencing factors of PD(P＜0.05).The ROC curves showed that the AUCs of the tremor peak frequency in the weight-bearing state,the tremor rhythm pattern in the resting state,and the frequency of tremor spectrum for diagnosing PD were 0.886,0.750,and 0.779,respec-tively.The combination of these three indicators yielded the highest AUC(0.936)for diagnosing PD,with a sensitivity of 81.54％and a specificity of 94.87％.Conclusion The tremor peak fre-quency in the weight-bearing state,the tremor rhythm pattern in the resting state,and the frequency of tremor spectrum provided by EMG tremor analysis can serve as clinical indicators for early diagno-sis of PD,and their combined use offers higher diagnostic value,which can be used to differentiate PD from ET.

Objective:To study the clinical characteristics and risk factors of nephrocalcinosis in preterm infants.Methods:From March 2021 to August 2021, all preterm infants admitted to NICU of our hospital were retrospectively analyzed. The infants were assigned into nephrocalcinosis group and non-nephrocalcinosis group according to urinary tract ultrasound. Clinical data including gestational age, birth weight(BW), nutritional support strategy and complications were reviewed.Results:A total of 40 preterm infants (<34 weeks) were enrolled. 9 cases were in the nephrocalcinosis group and 31 cases in the non-nephrocalcinosis group. The nephrocalcinosis group had lower BW[(1 167±214) g vs.(1 586±215) g], higher calcium [6.9 (5.1, 8.7) g vs.3.3 (2.1, 6.8) g] and vitamin D intake [3.2(2.5, 4.2)×10 4U vs.1.7(1.1, 3.2)×10 4U] during hospitalization. No significant differences existed between the two groups on the following items:blood calcium and phosphate, 25-hydroxyvitamin D, feeding strategy, time to reach full enteral feeding(TFF), furosemide dosage and respiratory support duration ( P>0.05). In the nephrocalcinosis group, the median age of diagnosing nephrocalcinosis was 40.0(30.0, 52.5)d after birth. 5 cases showed bilateral nephrocalcinosis. 5 cases in the nephrocalcinosis group received renal tubule function examination,4 cases had increased urine β2 microglobulin and 2 cases had increased urine α1 microglobulin. 7 cases had elevated urine calcium in the nephrocalcinosis group. Follow-up showed that nephrocalcinosis disappeared 3-9 months after birth. Conclusions:BW, total calcium and vitamin D intake are risk factors for nephrocalcinosis in preterm infants. Increased urine β2 microglobulin and calcium levels are common co-morbidities in preterm infants with nephrocalcinosis.

Objective:To explore the organizational identity, sense of coherence, perceived social support, and work engagement of surgical nurses in a traditional Chinese medicine hospital and the relationships between them.Methods:From March to May 2022, 450 surgical nurses were selected by convenience sampling from Guangdong Provincial Hospital of Traditional Chinese Medicine for a survey with a general information questionnaire, the Organizational Identification Scale, the Sense of Coherence Scale, the Perceived Social Support Scale, and the Utrecht Work Engagement Scale-9. SPSS 24.0 was used to perform Pearson correlation analysis. AMOS 24.0 was used for structural equation modeling.Results:The nurses' scores of organizational identity, sense of coherence, perceived social support, and work engagement were (26.00±5.00), (53.58±7.50), (47.47±7.50), and (30.06±1.00), respectively. The correlation analysis revealed positive correlations between organizational identity, sense of coherence, perceived social support, and work engagement ( r=0.369-0.741, all P<0.001). Sense of coherence played a partial mediating role between perceived social support and work engagement, and the mediating effect was 0.07, accounting for 12.07% of the total effect. Organizational identity and sense of coherence produced a chain mediating effect between perceived social support and work engagement, in which the mediating effect was 0.11, accounting for 18.97% of the total effect. Conclusions:Organizational identity and sense of coherence produce a chain mediating effect between perceived social support and work engagement in the surgical nurses of the traditional Chinese medicine hospital.

Objective:To explore the application of observation teaching discussion (OTD) in vascular surgery nursing intern teaching under the guidance of process-oriented guided inquiry learning (POGIL) theory.Methods:Forty nursing students who were doing their internship in The First Affiliated Hospital of Xi'an Jiaotong University from July 2022 to July 2023 were randomly divided into two groups using a random number table: control group (20 students, OTD teaching) and observation group (20 students, POGIL theory-guided teaching) . The two groups were compared for competence assessment scores before entering the department and 3 days prior to departure from the department, autonomous learning ability scale scores, Competency Inventory for Registered Nurses (CIRN) scores, and Chinese Problem Solving Inventory (CPSI) scores. T-tests and chi-square tests were conducted using SPSS 22.0. Results:Three days prior to departure from the department, the theoretical performance and practical performance were significantly better in the observation group [(91.67±5.22) and (89.69±4.36) points, respectively] than in the control group [(84.53±4.75) and (82.41±4.18) points, respectively] ( P<0.05). The observation group also performed significantly better than the control group in autonomous learning ability scale score [(139.52±13.52) vs. (128.86±10.76)], CIRN score [(207.73±6.23) vs. (195.67±5.98)], and CPSI score [(103.60±4.72) vs. (92.18±5.03)] (all P<0.05). Conclusions:The application of OTD in vascular surgery nursing intern teaching under the guidance of POGIL theory can improve the autonomous learning ability, core ability, and problem-solving ability of nursing interns.

Objective To compare the efficacy and safety of anlotinib(AL)and bevacizumab(BEVA)in the treatment of advanced lung adenocarcinoma(LUAD)with acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors(EGFR-TKI).Methods The clinical data of patients with EGFR-TKI-resistant LUAD who were treated in the Department of Oncology of Yibin Third People's Hospital from January 2022 to January 2023 were retrospectively analyzed.According to the treatment plan,patients were divided into BEVA group and AL group.Both groups were treated with BEVA injection or AL capsule in combination with standard chemotherapy for a total of 4 cycles.The main outcome measures included changes in tumor marker levels[carcinoembryonic antigen(CEA),neuron-specific enolase(NSE),and vascular endothelial growth factor(VEGF)],recent clinical efficacy[overall response rate(ORR)and disease control rate(DCR)],progression-free survival(PFS),1-year survival rate,and drug-related adverse reactions.Results A total of 60 patients with EGFR-TKI-resistant LUAD were included in the study,including 32 patients in the BEVA group and 28 patients in the AL group.After four cycles of treatment,the levels of serum CEA,NSE,and VEGF in both groups significantly decreased,and AL group was lower than BEVA group(P<0.05).There were no significant statistical differences in the complete remission rate,partial remission rate,disease stability rate,and ORR between the two groups(P>0.05).Compared with the BEVA group,the AL group had a lower rate of disease progression(P<0.05)and a higher DCR(P<0.05).In addition,the median PFS in the BEVA group was significantly longer than that in the AL group(8.4 vs.7.2 months,P<0.05),while there was no significant difference in survival rate between the two groups(P>0.05).In terms of adverse reactions,patients in the AL group had a lower incidence of nausea and vomiting,but a higher incidence of bone marrow suppression,resulting in a lower overall adverse reaction grade.Conclusion Compared with the BEVA combination chemotherapy regimen,AL combination chemotherapy showed better efficacy and good safety in the treatment of EGFR-TKI-resistant advanced LUAD.

Objective:To explore the application of effect of healthcare failure mode and effect analysis (HFMEA) in emergency waiting risk management.Methods:From May 2020 to April 2021, totally 87 902 emergency waiting patients from the First Affiliated Hospital of Anhui Medical University were assigned to control group by cluster sampling method. From May 2021 to April 2022, 80 594 emergency waiting patients were assigned to observed group. The patients in the control group received routine emergency waiting of itinerant management mode. In contrast, the patients in the observed group received emergency waiting risk management mode based on HFMEA. The process risk priority number (RPN) and waiting risk management index between two groups were compared.Results:The mean RPN of the observed group was (98.48 ± 8.27) points, significantly lower than that of the control group (251.27 ± 16.95) points. The nurses′ pre-identification rates of changes in the condition and adverse reaction in the observed group were 10.77%(8680/80 594) and 13.37%(10 775/80 594), which were higher than those in the control group, 5.77%(5072/87 902) and 8.12%(7134/87 902), the differences were statistically significant ( χ2 values were 1402.32 and 1221.66, all P<0.05). Conclusions:The application of HFMEA to optimize the emergency waiting management process can effectively reduce the risk of emergency waiting and improve the quality of emergency waiting management.
