Objective:To explore the intervention effect of virtual reality technology assisted early cardiac rehabilitation on exercise fear and self-efficacy after coronary artery bypass grafting (CABG), and provide theoretical basis for constructing intelligent and personalized cardiac rehabilitation models.Methods:A prospective non-contemporaneous controlled study was conducted. One hundred and two CABG patients admitted to the First Affiliated Hospital of the Chinese People's Liberation Army Naval Medical University were selected as the research subjects. They were divided into a control group (51 cases, from January to June 2024) and an experimental group (51 cases, from August to December 2024) according to their admission time, with July 2024 as the washout period. The control group received routine postoperative early cardiac rehabilitation intervention, while the experimental group received virtual reality technology intervention on the basis of the control group. The Tampa Scale of Kinesiophobia Heart (TSK-SV-Heart) and General Self-Efficacy Scale (GSES) were used to evaluate exercise fear and self-efficacy on the third day after surgery, one day before discharge, and one month after discharge, and the 6-minute walking distance was recorded at one day before discharge, and one month after discharge.Results:The control group consisted of 49 complete participants, aged (58.50 ± 5.88) years, with 26 males and 23 females, while the experimental group consisted of 48 complete participants, aged (60.31±6.58) years, with 30 males and 18 females. There was no statistically significant difference in the scores of exercise fear and self-efficacy between the two groups on the third day after surgery (both P>0.05). The exercise fear scores of the experimental group at one day before discharge and one month after discharge were (34.16 ± 5.76), (26.86 ± 4.52) points, respectively, which were lower than those of the control group (37.95 ± 6.14), (33.71 ± 5.49) points, and the differences were statistically significant ( t=3.13, 6.70, both P<0.05). The self-efficacy scores of the experimental group at one day before discharge and one month after discharge were (30.78 ± 3.49), (32.42 ± 3.37) points, respectively, which were higher than those of the control group (26.65 ± 4.21) , (26.54 ± 3.68) points, and the differences were statistically significant ( t=4.73, 8.25, both P<0.05). The 6-minute walking distance of the experimental group at one day before discharge and one month after discharge were (422.65 ± 74.32), (485.22 ± 76.84) m, respectively, which were longer than those of the control group (385.43 ± 68.17), (423.76 ± 62.75) m, and the differences were statistically significant ( t=2.57, 4.32, both P<0.05). Conclusions:Virtual reality technology can improve the fear of movement in patients after CABG surgery, enhance their self-efficacy, and simultaneously improve the 6-minute walking distance, providing a theoretical reference for the development of intelligent nursing measures after CABG surgery.

Objective To evaluate the effectiveness,safety and economy of generic venlafaxine sustained-release capsules and the original drug in clinical practice based on real world clinical data.Methods This is a multicenter,retrospective real-world study.The information of outpatients who used venlafaxine sustained-release capsules in 7 hospitals from October 2021 to October 2022 was collected,including prescription data and laboratory data.They were divided into generic drug group and original drug group.After the baseline level was corrected by propensity score match method,the prescription daily dose,plasma concentration,medication possession ratio,the continuous medication rate for 3,6 and 9 months,dressing change rate,the incidence of adverse reactions,the frequency of drug use,the average daily cost,the annual cost per capita and the proportion of the average annual cost of drugs were compared between the two groups.Results After the baseline level was corrected by propensity score matching method,the prescription daily dose and medication possession ratio(MPR≥0.8)in the generic drug group were higher than that of the original drug group(P＜0.05).There was no statistically difference in plasma concentration between the two groups(P=0.294).The continuous medication rate for 3,6 and 9 months in the generic drug group were statistically higher than those in the original drug group(P＜0.01).The single dressing change rate of the generic drug group was lower than that of the original drug group(P=0.032).There was no significant difference in the rate of secondary dressing change between the two groups(P=1.000).There were no significant differences in the incidence of abnormal ALT,AST,TC,Na,APTT,and PLC between two groups(P＞0.05).The average daily cost of the generic drug group was lower than that of the original drug group.The per capita annual cost of drugs and the proportion of average annual cost of drugs in the generic drug group were significantly lower than those in the original drug group(P＜0.01).Conclusion In the actual clinical diagnosis and treatment,no clinically significant differences in effectiveness and safety were found between the generic venlafaxine sustained-release capsule and the original-patented,while the economic advantages of the generic drug were better than that of the original-patented drug.

Objective To explore the predictive value of quantitative parameters of dual-layer detector spectral CT(DLCT)for Ki-67 expression in solid lung adenocarcinoma.Methods The data of 103 patients were retrospectively collected,and the patients were divided into Ki-67 high expression and Ki-67 low expression groups according to Ki-67 proliferation index.The quantitative parame-ters of DLCT were measured and calculated,and the differences in these parameters between the two groups were compared.The parameters with statistically significant differences were assessed for correlation with Ki-67 expression.The efficacy of DLCT param-eters and combined parameters in predicting Ki-67 expression in solid lung adenocarcinoma were evaluated by receiver operating character-istic(ROC)curve and compared by DeLong test.Results Long diameter,short diameter and smoking history were positively corre-lated with the Ki-67 expression in solid lung adenocarcinoma(r>0,P<0.05).Gender and quantitative parameters of DLCT were nega-tively correlated with the Ki-67 expression in solid lung adenocarcinoma(r<0,P<0.05).The combined parameters of convention and spectral CT had the highest prediction efficiency.Conclusion The quantitative parameters of DLCT can be used to evaluate the Ki-67 expres-sion in solid lung adenocarcinoma.

Objective:To compare the efficacy and safety of crisaborole ointment 2% versus pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged 2 years or older.Methods:A multicenter, randomized, open-label, controlled clinical trial was conducted. A total of 120 pediatric patients aged 2 - 17 years with mild to moderate atopic dermatitis were enrolled from departments of dermatology of 8 hospitals in China between March 2022 and February 2023. The participants were randomly assigned in a 1∶1 ratio to the crisaborole group and the pimecrolimus group, and received the treatment with crisaborole ointment 2% and pimecrolimus cream 1% respectively, twice a day for 4 weeks. Visits were scheduled at baseline/on day 1, as well as on days 8, 15, and 29. The primary efficacy outcome was the percentage of patients achieving the Investigator's Static Global Assessment (ISGA) success (defined as clear [0] or almost clear [1] on the ISGA scale, combined with ≥ 2‐grade improvement from baseline) on day 29. The secondary efficacy outcomes included changes in the Eczema Area and Severity Index (EASI) total scores from baseline to day 29, percentages of patients achieving ISGA improvement (defined as clear [0] or almost clear [1] on the ISGA scale), as well as changes in the Peak Pruritus Numerical Rating Scale (NRS) scores, Dermatology Life Quality Index (DLQI) /Infants' Dermatology Life Quality Index (IDLQI) /Children's Dermatology Life Quality Index (CDLQI) scores, and in the Dermatitis Family Impact (DFI) scores. Drug safety was evaluated according to the incidence of adverse events. Categorical data were compared using the chi-square test. Since measurement data did not follow a normal distribution, the rank sum test was used for comparisons of measurement data between groups.Results:A total of 106 children with mild to moderate atopic dermatitis were included in the per-protocol analysis set, with 52 in the crisaborole group (26 males and 26 females) and 54 in the pimecrolimus group (27 males and 27 females). There were no significant differences in age, disease duration, ISGA and EASI scores at baseline between the two groups (all P > 0.05). On day 29, 22 patients (42.31%) in the crisaborole group and 25 (46.30%) in the pimecrolimus group achieved ISGA success, with no significant difference between the two groups ( χ2 = 0.17, P = 0.68) ; 35 patients (67.31%) in the crisaborole group and 45 (83.33%) in the pimecrolimus group achieved ISGA improvement, also with no significant difference between the two groups ( χ2 = 3.68, P = 0.06) ; additionally, there were no significant differences in the EASI, pruritus NRS, DLQI/IDLQI/CDLQI, or DFI scores between the two groups (all P > 0.05). Adverse reactions to the two topical agents were mainly local reactions such as mild to moderate pain, itching, or worsening of itching, and no obvious systemic adverse reactions occurred. The incidence of drug-related adverse reactions was 46.15% (24 cases) in the crisaborole group and 37.04% (20 cases) in the pimecrolimus group, with no significant difference between the two groups ( χ2 = 0.91, P = 0.34) . Conclusion:The efficacy of crisaborole ointment 2% was comparable to that of pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged ≥ 2 years, and it yielded early and rapid improvement in the quality of life of patients and their families, with good safety and tolerability profiles.

Objective:To assess the application value of one-hour post-load glucose (1hPG) for detecting prediabetes among individuals with high risk of type 2 diabetes mellitus (T2DM).Methods:The study was conducted between August 2023 and January 2024, and individuals with a high risk of T2DM were invited to receive an oral glucose tolerance test (OGTT), structural questionnaires, physical measurements, and other biochemical examinations. The fasting, one-, and two-hour glucose and insulin were tested. According to the 1hPG cut point on hyperglycemia suggested by International Diabetes Federation (IDF), normal glucose tolerance (NGT) and prediabetes were further divided into two subgroups, respectively, i.e., NGT with 1hPG<8.6 mmol/L (NGT-1hPG-normal), NGT with 1hPG≥8.6 mmol/L (NGT-1hPG-high), prediabetes with 1hPG<8.6 mmol/L (PDM-1hPG-normal), and prediabetes with 1hPG≥8.6 mmol/L (PDM-1hPG-high). The insulin release curve was drawn by the groups as above. Insulin resistance was evaluated by homeostasis model assessment for insulin resistance (HOMA-IR), and β-cell secretory function was evaluated by homeostasis model assessment for β cell function (HOMA-β)/HOMA-IR. Spearman rank correlation analysis was used to calculate the correlation coefficients among 1hPG, 2hPG and HOMA indices, and Steiger′s Z test was used to compare the difference between two correlation coefficients. Receiver operating characteristics (ROC) curves and area under the curve (AUC) were used to assess the accuracy of 1hPG for detecting prediabetes. Results:A total of 2 469 subjects consisting of 1 485 men (60.1%) and 984 (39.9%) women, with a mean age of (45.76±6.20) years, of which 1 844 (74.7%) had 1hPG≥8.6 mmol/L. The prevalence of 1hPG≥8.6 mmol/L was 46.8%, 93.0% and 99.8% in individuals with NGT, prediabetes and newly diagnosed T2DM, respectively ( χ 2=763.78, P<0.001). The insulin release curve showed that insulin secretion increased rapidly in subjects with NGT-1hPG-high, and peaked at one hour, then decreased rapidly, with a significantly higher level of one- and two-hour insulin than those with NGT-1hPG-normal ( P<0.001). Compared to individuals with NGT-1hPG-normal, the counterparts with NGT-1hPG-high exhibited higher HOMA-IR and lower adjusted HOMA-β ( P<0.001). Spearman rank correlation analysis showed that the correlation coefficient of 1hPG with HOMA-IR was similar to the correlation coefficient of 2hPG with HOMA-IR (0.493 vs. 0.480, P=0.550), while the correlation of 1hPG with adjusted HOMA-β was significantly stronger than that of 2hPG (-0.692 vs. -0.587, P<0.001). Excluding patients with T2DM, according to the cut point recommended by IDF, the AUC of 1hPG≥8.6 mmol/L for detecting prediabetes was 0.731 (95% CI: 0.714-0.748), and the sensitivity and specificity were 0.930 and 0.532, respectively, with the kappa value of 0.45. Conclusion:1hPG is closely related to insulin resistance and islet function, and there′s substantial value for individuals with a high risk of T2DM to detect prediabetes by using the 1hPG cut points recommended by IDF.

Objectives:There is a lack of long-term follow-up study results on severe microvascular complications in a larger Chinese population with diabetes.This study aims to explore long-term impact of newly diagnosed diabetes(NDD)on the incidence and risk of severe microvascular complications.Methods:A total of 598 NDD and 493 normal glucose tolerance(NGT)subjects were included in this study in 1986.By questionnaire and systematic case review,the occurrence of severe microvascular complications,including severe diabetic retinopathy,severe diabetic nephropathy,and severe diabetic neuropathy,was followed up and collected over a period of 34 years.Results:The cumulative incidence of severe microvascular complications in the NDD population was 65.03%(95%CI:58.90%-70.48%)over 34 years,significantly higher than that in the NGT population(16.8%,95%CI:12.64%-20.11%).After adjusting for related risk factors,the risk of severe microvascular complications in the NDD population was 7.08 times than that of the NGT population(HR=7.08,95%CI:5.09-9.84,P<0.0001).Stratified analysis by sex showed that the cumulative incidence and risk of severe microvascular complications were slightly higher in male NDD population(68.02%,95%CI:57.27%-76.61%;HR=9.45,95%CI:5.78-15.47,P<0.0001)than in female NDD population(63.37%,95%CI:55.69%-70.09%;HR=5.86,95%CI:3.75-9.16,P<0.0001);however,the cumulative incidence increased more rapidly in women during the follow-up period of 10-25 years.Conclusions:The incidence and risk of severe microvascular complications in diabetes were significantly higher than those in the NGT population;and the incidence of severe vascular complications increased rapidly after the duration of diabetes exceeded 10 years,indicating that strict control of blood glucose in the early stage of diabetes is of vital importance.

Objective:To explore the current status and influencing factors of quality of life in patients with thyroid-associated ophthalmopathy (TAO) .Methods:From January to July 2024, convenience sampling was used to select TAO patients of the Department of Ophthalmology of Peking University Third Hospital as research subjects. The patients were surveyed using the General Information Questionnaire, Graves' Ophthalmopathy Quality of Life Questionnaire (GO-QOL), Negative Physical Self Scale-Appearance (NPSS-A), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and Perceived Social Support Scale (PSSS). Spearman correlation analysis was used to explore the correlation between GO-QOL scores and NPSS-A, SAS, SDS, and PSSS scores. Multiple linear regression was used to analyze the factors influencing the quality of life of TAO patients.Results:A total of 234 questionnaires were distributed, and 203 valid questionnaires were collected, with a valid response rate of 86.75%. The GO-QOL visual function and social function dimensions scores of 203 TAO patients were [78.57 (50.00, 100.00) ] and [43.75 (18.75, 62.50) ], respectively. Multiple linear regression analysis showed that age, eye movement disorders, eyelid retraction, and disease grading, were the influencing factors of the visual function dimension of GO-QOL ( P<0.05). Age, social support, and body image were the influencing factors on the social function dimension of GO-QOL ( P<0.05) . Conclusions:The quality of life of TAO patients is poor. Healthcare professionals should develop coping strategies based on factors affecting different dimensions of quality of life, so as to improve patients' quality of life.

Objective To develop an automated system that can accurately determine the relationship between the mandibular third molar and the mandibular nerve canal from panoramic images.Methods A dataset consisting of 600 panoramic images of the oral cavi-ty was selected,and the positions of the mandibular third molar and the mandibular nerve canal were accurately labeled.We compared the research designed TI-YOLOv5 with PANet,Faster R-CNN,Mask R-CNN,ResNeSt-101,and the original YOLOv5 in image seg-mentation tasks,with evaluation metrics of AP and AP50.Results TI-YOLOv5 achieved AP(average precision)54.0％and AP5094.9％,an increase of 4.9 and 6.7 percentage points respectively compared to the original YOLOv5(AP 49.1％,AP50 88.2％),and surpassed other SOTA methods such as Mask R-CNN(AP 45.1％,AP50 84.2％).Conclusion TI-YOLOv5 is significantly superior to mainstream networks in automatic positioning and relationship classification of mandibular wisdom teeth and neural tubes,with high de-tection accuracy and discrimination accuracy,and can provide reliable technical support for preoperative risk assessment of mandibular wisdom tooth extraction.

Objective:To analyze the correlation between respiratory event duration and nocturnal oxygen saturation (SpO 2) in adults with obstructive sleep apnea (OSA), and to explore its significance in assessing nocturnal hypoxemia and OSA severity. Methods:A prospective study was conducted on adult OSA patients diagnosed via overnight standard polysomnography (PSG) at the Department of Otolaryngology, First Affiliated Hospital of Sun Yat-sen University from June 2019 to December 2023. Data collected included demographic information, PSG reports, scale scores, and comorbidities. Patients were first stratified by apnea-hypopnea index (AHI) severity. Relationships between respiratory event duration parameters,including total apnea-hypopnea time (TAHT), percentage of total sleep time with apnea-hypopnea (AHT%), total apnea time (TAT), total hypopnea time (THT), and mean apnea-hypopnea time (MAHT), and nocturnal SpO? parameters, including average SpO? (aSpO?), minimal SpO? (mSpO?), mean oxygen desaturation (MOD), and percentage of total sleep time with SpO?<90% (CT90), were analyzed. Patients were then divided into two groups based on the median MAHT (27.6 s) for SpO? comparison. Finally, severe OSA patients were further subclassified using an AHI inflection point (50 events/h) identified via scatter plot analysis to compare nocturnal SpO?. Statistical analysis was performed using SPSS 27.0.Results:Among the 250 study subjects, there were 201 males and 49 females, with ages ranging from 18 to 76 years (mean age: 41.6 ± 11.9 years).TAHT, AHT%, and TAT in OSA patients demonstrated significant negative correlations with aSpO?( r=-0.698, -0.718, -0.646)and mSpO?( r=-0.746, -0.746, -0.748), while showing positive correlations with MOD ( r=0.783, 0.791, 0.823)and CT90 ( r=0.868, 0.866, 0.852), P<0.05. When stratified by MAHT median ( M=27.6 s), the "long-event" subgroup ( n=125) displayed significantly lower mSpO 2 and higher MOD and CT90 compared to the "short-event" subgroup ( n=125), Z=-3.319, 3.288, 2.242; P<0.05. No significant difference in aSpO 2 was observed ( P>0.05). Subgrouping severe OSA patients at AHI=50 events/hour revealed significant differences in aSpO 2, mSpO 2, MOD, and CT90 between groups ( Z=-5.011, -4.787, 5.142, 6.117, P<0.05). Conclusions:TAHT, AHT%, and TAT significantly correlate with nocturnal SpO? parameters in OSA patients and can supplement AHI in assessing OSA severity. MAHT independently reflects nocturnal oxygenation status beyond AHI.
