Objective: To explore the types of medication adherence and their influencing factors among inpatients with chronic diseases based on latent profile analysis, so as to provide the basis for improving medication adherence among patients with chronic diseases. Methods: The inpatients with chronic diseases admitted to the Second Affiliated Hospital of Hainan Medical University were selected as the study subjects. Demographic information, chronic disease status, and health education were collected through questionnaire surveys. Medication adherence was assessed using the Medication Adherence Scale and categorized based on the scores of its eight items through latent profile analysis. Factors affecting medication adherence among inpatients with chronic diseases were analyzed using a multinomial logistic regression model. Results: Totally 290 valid questionnaires were recovered, with an effective recovery rate of 97.64%. There were 157 males (54.14%) and 133 females (45.86%), with a median age of 61 (interquartile range, 21) years. The median score of medication adherence was 4.75 (interquartile range, 4.50). Based on latent profile analysis, medication adherence was categorized into three types: subjective neglect with poor adherence (38.97%), subjective confidence with fluctuating adherence (28.28%), and self-reflective with good adherence (32.76%). Multinomial logistic regression analysis showed that compared to the subjective confidence with fluctuating adherence, family monthly income (5 000-10 000 yuan, OR=2.981, 95%CI: 1.055-8.429), comorbidity of chronic diseases (OR=3.478, 95%CI: 1.579-7.661), number of health education sessions received in the past year (≤1 session, OR=0.329, 95%CI: 0.120-0.907; 2 sessions, OR=0.363, 95%CI: 0.138-0.950), and health information literacy scores (<60 points, OR=2.596, 95%CI: 1.209-5.573) were statistically associated with subjective neglect with poor adherence (all P<0.05). Conclusion Subjective neglect with poor medication adherence among inpatients with chronic diseases is associated with family monthly income, comorbidity of chronic diseases, the number of health education sessions received, and health information literacy.

Background::Breast cancer (BC) risk-stratification tools for Asian women that are highly accurate and can provide improved interpretation ability are lacking. We aimed to develop risk-stratification models to predict long- and short-term BC risk among Chinese women and to simultaneously rank potential non-experimental risk factors.Methods::The Breast Cancer Cohort Study in Chinese Women, a large ongoing prospective dynamic cohort study, includes 122,058 women aged 25-70 years old from the eastern part of China. We developed multiple machine-learning risk prediction models using parametric models (penalized logistic regression, bootstrap, and ensemble learning), which were the short-term ensemble penalized logistic regression (EPLR) risk prediction model and the ensemble penalized long-term (EPLT) risk prediction model to estimate BC risk. The models were assessed based on calibration and discrimination, and following this assessment, they were externally validated in new study participants from 2017 to 2020.Results::The AUC values of the short-term EPLR risk prediction model were 0.800 for the internal validation and 0.751 for the external validation set. For the long-term EPLT risk prediction model, the area under the receiver operating characteristic curve was 0.692 and 0.760 in internal and external validations, respectively. The net reclassification improvement index of the EPLT relative to the Gail and the Han Chinese Breast Cancer Prediction Model (HCBCP) models for external validation was 0.193 and 0.233, respectively, indicating that the EPLT model has higher classification accuracy.Conclusions::We developed the EPLR and EPLT models to screen populations with a high risk of developing BC. These can serve as useful tools to aid in risk-stratified screening and BC prevention.

Objective To study the effectiveness of pro-abdominal exercise in improving the quality of gastroscopy,and provide patients with a better preoperative preparation for gastroscopy.Methods 307 patients who underwent painless gastroscopy from March to July 2023 were selected and divided into three groups according to the random number table method.There were 106 cases in the abdominal massage group,103 cases in the bed turning group and 98 cases in the control group.On the basis of routine medication,different preoperative activity guidance was used to compare and analyze the preoperative preparation time,examination time and gastric mucosal visual field clarity score in each group.Results The gastroscopy time in the abdominal massage group and the bed-turning group was significantly shorter than that in the control group,and the clarity score of the gastric mucosal visual field was significantly lower than that of the control group,with statistically significant differences(P<0.05).However,there were no statistically significant differences in the gastroscopy time or visual field clarity score for gastric body,gastric fundus,and gastric antrum between the abdominal massage group and the bed-turning group(P>0.05).The satisfaction rate of endoscopists in the abdominal massage group and the bed turning group was higher than that in the control group,and the differences were statistically significant.Conclusion Abdominal massage and turning over in bed as preoperative preparation methods for gastroscopy can improve the quality of gastroscopy,while abdominal massage can shorten the preparation time before gastroscopy,which is helpful for the efficient operation of digestive endoscopy center and is worthy of clinical application.

Objective:To investigate the predictive value of differential distribution of peripheral lymphocyte subsets before and after the first 131I treatment on the therapeutic response to 131I treatment in patients with papillary thyroid cancer (PTC). Methods:A retrospective study was conducted on 46 PTC patients (16 males, 30 females, age 20-77 years) who underwent total thyroidectomy and received 131I treatment between January 2021 and August 2021 in First Hospital of Shanxi Medical University. Peripheral blood lymphocyte subsets (T, B, CD4 + T, CD8 + T, natural killer (NK), helper T (Th)1, Th2, Th17, and regulatory T (Treg) cells) were measured 1-2 d before and 30 d after 131I treatment. Based on serological and imaging evidence, therapeutic response at 6-12 months post- 131I therapy was categorized as either excellent response (ER) or non-excellent response (NER). Differences of preablative stimulated thyroglobulin (psTg) and clinical baseline characteristics between two groups were assessed by using independent-sample t test, paired t test, or Mann-Whitney U test. Predictive value of lymphocyte subsets before and after 131I treatment for therapeutic response was assessed through logistic regression analysis, ROC curve analysis, and decision curve analysis (DCA). Results:In ER group ( n=33) and NER group ( n=13), most lymphocyte subsets showed different degrees of reduction 30 d after 131I treatment compared to before 131I treatment, such as T, B, CD4 + T and Th1 cells in ER group, as well as T, B, CD4 + T, Th1, Th2, Th17, and Treg cells in NER group ( t values: 2.41-9.57, all P<0.05). Before 131I treatment, NER group had significantly higher levels of psTg, Th2, Th17, and Treg cells compared to the ER group ( t values: from -3.32 to -2.48, U=29.00, all P<0.05). After 131I treatment, most of lymphocyte subsets in NER group (T, B, CD4 + T, CD8 + T, Th1 and Treg cells) showed higher trend than those in ER group but without statistical significances ( t values: from -1.12 to -0.06, all P>0.05). Th2 cells before 131I treatment (odds ratio ( OR)=25.00, 95% CI: 1.36-459.10, P=0.030) was identified as a risk factor for NER. ROC curve analysis indicated that AUCs of psTg and Th2 cells for predicting therapeutic response were 0.932 and 0.790, respectively, which was 0.958 for the combined psTg and Th2 cells. DCA showed that within the threshold probability range of 10%-60%, the curves for psTg, Th2 cells, and the combined psTg and Th2 cells were all higher than the extreme curve, suggesting good effect. Conclusions:Most lymphocyte subsets decrease to varying degrees, and NER group shows a significant decrease 30 d after 131I treatment. Th2 cells may be a risk factor for poor response to 131I treatment, providing a certain value in predicting the therapeutic response to 131I treatment.

Objective:To determine the efficacy and influencing factors of thymectomy for bulbar myasthenia gravis.Methods:The clinical data of 120 patients with bulbar myasthenia gravis admitted to the Myasthenia Gravis Comprehensive Diagnosis and Treatment Center of Henan Provincial People's Hospital from March 2018 to June 2023 were collected, with 61 males and 59 females. There were 66 patients with thymoma and 54 patients with non-thymoma. The duration of bulbar muscle involvement before operation ranged from 11 days to 108 months. Preoperative AChR-Ab was positive in 105 cases and negative in 15 cases. There were 28 cases with bulbar muscle involvement as the initial symptom and 92 cases as the non-initial symptom. There were 7 cases with crisis and 113 cases without crisis in the past. The postoperative efficacy was evaluated according to the Myasthenia Gravis post-treatment status evaluation program of the American Myasthenia Gravis Society. Univariate analysis and logistic regression analysis were used to analyze the factors that may affect the surgical efficacy. Results:All 120 patients successfully underwent extended thymectomy, there was no perioperative death. The follow-up time was 3-57 months, with a median of 24 months. Twenty-two patients (18.33%) achieved complete durable remission, 1 patient (0.83%) maintained remission, 65 patients (54.17%) had minimal symptoms, and 20 patients (16.70%) improved. No change in 8 cases (6.67%), no aggravation cases (0), deterioration in 2 cases (1.67%), and death in 2 cases (1.67%). 23 cases(19.17%) achieved clinical remission and 85 cases (70.83%) achieved partial remission. Univariate analysis showed that positive AChR-Ab before operation and duration of bulbar muscle involvement before operation were the influencing factors of surgical efficacy in patients with bulbar MG, and the difference was statistically significant ( P<0.05). Logistic regression analysis showed that positive AChR-Ab before operation and the duration of bulbar muscle involvement before operation were independent influencing factors of surgical efficacy. Conclusion:Thymectomy can effectively relieve the symptoms of bulbar myasthenia gravis. Patients with positive AChR-Ab before surgery and shorter duration of bulbar muscle involvement may benefit more from thymectomy.

Taking the reform of payment methods based on diagnosis related groups as an opportunity, implementing performance management based on disease groups is an important lever to promote the improvement of hospital diagnosis and treatment level and high-quality development. In 2023, a tertiary comprehensive hospital introduced benchmarking management into performance management, using the average days of stay, drug costs, and consumables costs of the disease group as cost benchmark indicators. The cost benchmark values for each disease group was determined based on the big data of the disease group of the tertiary comprehensive hospital in the region and the clinical pathway management goals of the hospital. Through multidimensional and multi-level comparative analysis of the hospital′s historical values and regional big data distribution values of the benchmark indicators for each disease group, the cost benchmark values for each disease group was determined. The hospital has established a performance reward and punishment mechanism based on the benchmark value of disease group costs, and at the same time, established a performance management communication mechanism to promote relevant departments and medical groups to improve their management against the benchmark. In addition, with changes in the external environment and internal practices, the cost benchmark value of the disease group was dynamically optimized, forming a closed-loop management system that included establishing benchmarks, comparing benchmarks, achieving benchmarks, and optimizing benchmarks. Since the implementation of performance management based on disease group cost benchmarking in March 2023, the hospital′s case mix index has increased from 1.52 in March to 1.54 in September; The average days of stay decreased from 6.22 days to 5.90 days; The monthly payment weight has increased from 18 103 to 18 558; The average hospitalization cost has decreased from 16 724 yuan/person to 15 278 yuan/person, mainly due to the decrease in drug and consumables costs. The proportion of drug costs has decreased from 27.45% to 26.32%, the proportion of consumables costs has decreased from 28.75% to 26.85%, and the proportion of medical service revenue has increased from 24.64% to 26.08%; The proportion of low magnification cases decreased from 9.09% to 8.24%; The medical insurance payment rate has increased from 99.3% to 107.0%; The job satisfaction of physicians has increased from 70.00% in 2022 to 76.77% in 2023, which can provide reference for performance management practices in other hospitals.

Objective To analyze the diagnostic values of H2FPEF and HFA-PEFF scores for heart failure with preserved ejection fraction(HFpEF)and HFpEF complicated with atrial fibrillation(HFpEF-AF)in Chinese patients and explore the related factors.Methods A cross-sectional study was conducted.A total of 835 consecutive HFpEF patients treated in the Department of Geriatric Cardiology,the First Hospital of Lanzhou Uni-versity from 2009 to 2020 were selected and assigned to a HFpEF-AF group(n =267)and a HFpEF group(n = 568)according to the presence of AF or not.HFA-PEFF and H2FPEF scores were used for retrospective diagnosis and the diagnostic consistency of the two scores was assessed.One hundred and thirty-six healthy volunteers with age and sex matching the patients during the same period were selected as healthy controls.The receiver operating characteristic(ROC)curves were established for H2FPEF and HFA-PEFF scores in diagnosing HFpEF-AF and HFpEF,on the basis of which the diagnostic performance of the two scores was evaluated.Results There was no difference in the HFA-PEFF score between the two groups(P =0.070).However,the HFpEF-AF group had higher mean H2FPEF score and higher proportion of patients with the score no less than 6 than the HFpEF group(P<0.001).According to the ROC curves,HFA-PEFF and H2FPEF scores demonstrated high perform-ance in diagnosing all HFpEF patients,with the area under the curve(AUC)of 0.892 and 0.922 and the opti-mal cut-offs of 4 and 4,respectively.The HFA-PEFF score showed similar performance in diagnosing HFpEF and HFpEF-AF,with the AUC of 0.899 and 0.911,respectively.The H2FPEF score had higher performance in di-agnosing HFpEF-AF(AUC of approximately 1.000)and low performance in diagnosing HFpEF(AUC of 0.885).Conclusions The HFA-PEFF score is applicable in the diagnosis of both HFpEF and HFpEF-AF.The H2FPEF score may underestimate HFpEF in Chinese patients,and its applicability in the Chinese patients with HFpEF alone remains to be investigated.

ObjectiveTo establish a mouse model of basilar artery dolichoectasia （BAD） and explore the mechanism of modified Tongqiao Huoxuetang （JTQHX） in regulating BAD via phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） pathway. MethodSixty C57/BL6 female mice were randomized into sham operation （injected with 10 U·mL^-1 inactivate elastase）， model， atorvastatin calcium tablets （2.6 mg·kg·d^-1）， and low- and high-dose （crude drug 3.4， 17 g·kg^-1·d^-1， respectively） JTQHX groups. The mouse model of BAD was established by injection with 10 U·mL^-1 elastase. After 14 days of modeling， the sham operation group and model group were administrated with equal volumes of pure water by gavage， and other groups with corresponding drugs for 2 months. The levels of interleukin-6 （IL-6） and calpain （LpA） in the serum were measured by enzyme-linked immunosorbent assay （ELISA）. Verhoeff 's Van Gieson （EVG） staining was employed to observe the pathological changes of blood vessels. Terminal-deoxynucleotidyl transferase mediated nick end labeling （TUNEL） was employed to examine the apoptosis rate of vascular smooth muscle cells （VSMCs）. Image Pro Plus was used to observe and calculate the curvature index， elongation length， percentage increase in vessel diameter， and curvature angle of the basilar artery vessels in mice. Western blot was employed to determine the expression levels of PI3K and Akt in the vascular tissue. ResultCompared with the sham operation group， the model group showed lowered IL-6 level （P<0.01）， no significant change in LpA level， increased apoptosis of VSMCs （P<0.01）， and increased curvature index， elongation length， percentage increase in vessel diameter， and curvature angle （P<0.01）. Furthermore， the modeling up-regulated the protein levels of PI3K and Akt in blood vessels （P<0.01） and aggravated the destruction of the inner elastic layer， atrophy of the muscular layer， and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. Compared with the model group， 2 months of treatment with JTQHX elevated the IL-6 level （P<0.01）， reduced the apoptosis of VSMCs （P<0.01）， decreased the curvature index， elongation length， percentage increase in vessel diameter， and curvature angle （P<0.05， P<0.01）， and down-regulated the protein levels of PI3K and Akt in blood vessels （P<0.01）. In addition， the treatment alleviated the destruction of the inner elastic layer， atrophy of the muscular layer， and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. ConclusionJTQHX inhibits the elongation， expansion， and curvature of basilar artery vessels and alleviates the pathological changes by reducing the apoptosis of VSMCs and down-regulating the expression of PI3K/Akt pathway.

Objective:To analyze the efficacy of anterior cervical Hybrid surgery and posterior cervical expansive open-door laminoplasty(EODL)in the treatment of multilevel cervical spondylotic myelopathy,and to discuss the selection of surgical methods for the patients with multilevel cervical spondylotic myelopathy.Methods:The retrospective analysis was conducted of 70 patients with multilevel cervical spondylotic myelopathy who underwent surgery at Affilated Beijing Traditional Chinese Medicine Hospital of Capital Medical University from July 2017 to July 2020.Based on the different surgical methods,the patients were divided into anterior group(n=35)and posterior group(n=35).The patients in anterior group underwent Hybrid surgery[anterior cervical discectomy and fusion(ACDF)combined with artificial cervical disc replacement(ACDR)],and the patients in posterior group underwent EODL.The hospitalization time,operation time,intraoperative blood loss,and postoperative drainage volume of the patients in two groups were recorded;the efficacy was evaluated by Japanese orthopaedic association(JOA)score,JOA improvement rate,neck disability index(NDI),visual analogue scale(VAS)for pain,and postoperative satisfaction score;the complications of the patients in two groups after surgery were recorded.Results:Compared with posterior group,the intraoperative blood loss,postoperative drainage volume,hospitalization time,and operation time of the patients in anterior group were significantly decreased(P<0.01),and the preoperative score had no significant difference(P>0.05).At the final follow-up after surgery,compared with posterior group,the JOA score and JOA improvement rate of the patients in anterior group were significantly increased(P<0.01),and the NDI score and VAS score were significantly decreased(P<0.01).Compared with before surgery,the JOA scores of the patients in two groups at the final follow-up after surgery were increased(P<0.01),and the NDI and VAS scores were significant decreased(P<0.01).The postoperative satisfaction of the patients in two groups was high based on the postoperative satisfaction score.There was no significant difference in the incidence of postoperative complication of the patients between two groups(P>0.05).Conclusion:Both the anterior cervical Hybrid surgery and EODL achieve the satisfactory results in the treatment of multilevel cervical spondylotic myelopathy.Hybrid surgery has the advantages of less bleeding and shorter surgery time,and the most suitable surgical method should be chosen clinically based on the actual situation of the patients.
