Objective:To evaluate the effects of different volumes of ropivacaine for iliopsoas muscle plane block on quadriceps strength in patients undergoing hip arthroplasty.Methods:In this prospective study, 75 patients of either sex, aged 40-80 yr, with a body mass index of 18.5-30.0 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, undergoing elective hip arthroplasty from June to December 2023 at Baoding First Central Hospital, were randomized into 3 groups ( n=25 each) by using a computer-generated randomization sequence: ropivacaine 5 ml group (group Ⅰ), ropivacaine 10 ml group (group Ⅱ), and ropivacaine 15 ml group (group Ⅲ). Before induction of anesthesia, iliopsoas muscle plane block was performed with 0.5% ropivacaine 5, 10 and 15 ml in Ⅰ, Ⅱ and Ⅲ groups, respectively. The lateral femoral cutaneous nerve block was carried out using 0.5% ropivacaine 5 ml in all the three groups. The quadriceps muscle strength and status of quadriceps motor block in the affected limb were assessed on admission to postanesthesia care unit (PACU) and at 2, 4, 6, 24 and 48 h after surgery. The consumption of dezocine, score for patient′s satisfaction with analgesia, and occurrence of complications were recorded. Results:Compared with group Ⅰ, the quadriceps muscle strength scores were significantly decreased on admission to PACU and at 2, 4 and 6 h postoperatively in group Ⅲ, the rate of quadriceps motor block was significantly increased on admission to PACU in group Ⅱ, and the rate of quadriceps motor block was significantly increased on admission to PACU and at 2 and 4 h postoperatively in group Ⅲ ( P<0.05), and the consumption of dezocine was significantly decreased in group Ⅱ and group Ⅲ ( P<0.05). Conclusions:The recommended volume of ropivacaine for iliopsoas plane block is 10 ml in patients undergoing hip arthroplasty.

ObjectiveTo explore the distribution characteristics of traditional Chinese medicine （TCM） syndrome elements of macroangiopathy in patients with type 2 diabetes mellitus （T2DM） and the key elements of occurrence， development and progression of disease. MethodsA multicenter cross-sectional study was conducted to enroll 445 T2DM patients from five hospitals， and according to the presence or absence of macroangiopathy， the patients were divided into a T2DM group （120 cases） and a diabetic macroangiopathy （DM） group （325 cases）. Patients in DM group were divided into grade Ⅰ， Ⅱ， Ⅲ and Ⅳ according to the peripheral vascular color Doppler ultrasound results and the vascular anomalies classification standard. The general data including gender， age， duration of T2DM and body mass index （BMI） were collected， and the data of four examinations were obtained for syndrome differentiation. According to the diagnostic criteria of TCM syndrome elements， the patients can be divided into 9 patterns including qi deficiency， blood deficiency， yin deficiency， yang deficiency， qi stagnation， blood stasis， excess heat， and excess cold. The general data and distribution of TCM syndrome elements were compared between the two groups. The distribution of TCM syndrome elements in different vascular anomalies grades in the DM group was analyzed. Logistic regression analysis was used to explore the influence of various TCM syndrome elements on the occurrence of macroangiopathy in T2DM. ResultsThere was no significant difference in gender and BMI between groups （P＞0.05）. The age and duration of diabetes in the DM group were older and longer than those in the T2DM group （P＜0.01）. With the increase of age and prolonged course of disease， the severity of diabetic macroangiopathy increases gradually （P＜0.05 or P＜0.01）. There was no significant difference in BMI and course of disease among the different TCM syndrome elements （P＞0.05）. The average age of patients with blood stasis syndrome was the oldest （P＜0.05）. There was significant difference in gender distribution between the excess heat syndrome and yin deficiency syndrome （P＜0.05）. A total of 240 TCM syndrome elements were extracted from the T2DM group， while 731 TCM syndrome elements extracted from the DM group. The top two high-frequency syndrome elements in the two groups were qi deficiency and yin deficiency， with a frequency of larger than 50%. The distribution of phlegm-damp syndrome and blood-stasis syndrome were significantly higher in the DM group than in the T2DM group （P＜0.01）. There were significant differences in the distribution of qi deficiency syndrome， yin deficiency syndrome， phlegm-damp syndrome， blood stasis syndrome， and excess heat syndrome among different grades of vascular anomalies （P＜0.01）； qi deficiency and yin deficiency were both high-frequency TCM syndrome elements in patients at grades 0 to Ⅲ； phlegm-damp syndrome increased in frequency with the progression of the disease from grades 0 to Ⅳ， and the frequency of blood stasis syndrome showed an overall upward trend. The frequency of phlegm-dampness syndrome increased from grades 0 to Ⅳ with the progression of the disease， and the frequency of blood stasis syndrome showed an overall upward trend. Logistic regression analysis showed that phlegm-damp syndrome and blood stasis syndrome were important TCM syndrome elements related to the vascular anomalies degree of macrovascular disease in T2DM （P＜0.05 or P＜0.01）. ConclusionQi deficiency and yin deficiency are the basic TCM syndrome elements throughout the whole process of T2DM and diabetic macrovascular disease. Phlegm-damp and blood stasis are related to the degree of vascular anomalies in diabetic macrovascular disease and are the key TCM syndrome elements in the progression of macroangiopathy in T2DM.

Purpose: Prostate cancer (PCa) is an epithelial malignancy that originates in the prostate gland and is generally categorized into low, intermediate, and high-risk groups. The primary diagnostic indicator for PCa is the measurement of serum prostate-specific antigen (PSA) values. However, reliance on PSA levels can result in false positives, leading to unnecessary biopsies and an increased risk of invasive injuries. Therefore, it is imperative to develop an efficient and accurate method for PCa risk stratification. Many recent studies on PCa risk stratification based on clinical data have employed a binary classification, distinguishing between low to intermediate and high risk. In this paper, we propose a novel machine learning (ML) approach utilizing a stacking learning strategy for predicting the tripartite risk stratification of PCa. Methods: Clinical records, featuring attributes selected using the lasso method, were utilized with 5 ML classifiers. The outputs of these classifiers underwent transformation by various nonlinear transformers and were then concatenated with the lasso-selected features, resulting in a set of new features. A stacking learning strategy, integrating different ML classifiers, was developed based on these new features. Results: Our proposed approach demonstrated superior performance, achieving an accuracy of 0.83 and an area under the receiver operating characteristic curve value of 0.88 in a dataset comprising 197 PCa patients with 42 clinical characteristics. Conclusions This study aimed to improve clinicians’ ability to rapidly assess PCa risk stratification while reducing the burden on patients. This was achieved by using artificial intelligence-related technologies as an auxiliary method for diagnosing PCa.

Objective:To investigate the clinical effects of the modified posteromedial approach combined with the anterolateral approach in the treatment of posterior pilon fractures in the supine position.Methods:A retrospective was conducted to analyze the clinical data of 54 patients [45 males and 9 females with an age of (47.7 ± 13.1) years] who had been treated surgically for posterior pilon fractures from January 2016 to December 2020 at Department of Orthopedics, Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. The patients were divided into 2 groups according to their surgical positions: a supine group of 24 patients (the modified posteromedial approach combined with the anterolateral approach in the supine position) and a prone group of 30 patients (the posteromedial approach combined with the anterolateral approach in the prone position). The 2 groups were compared in terms of operation time, hospitalization time, radiographic outcomes (bone union time and ratio of congruent articular reduction), range of ankle motion, and postoperative complications. The post-operative function was evaluated using the Manchester Oxford Foot Questionnaire (MOXFQ) and the visual analogue scale (VAS).Results:There was no statistically significant difference between the 2 groups in the general clinical data before operation, showing comparability ( P>0.05). The mean follow-up time was (19.4 ± 4.4) months for the supine group and (17.8 ± 4.2) months for the prone group. The operation time, hospitalization time, bone union time, rate of fixation of syndesmosis and ratio of congruent articular reduction were (90.8 ± 9.9) min, (9.5 ± 2.4) d, (8.4 ± 1.4) weeks, 33.3% (8/24) and 95.8% (23/24) in the supine group, and (89.1 ± 10.8) min, (9.5 ± 2.5) d, (8.1 ± 1.4) weeks, 53.3% (16/30) and 96.6% (29/30) in the prone group, showing no significant differences (all P>0.05). At the last follow-up, the dorsiflexion and plantar flexion of the ankle, VAS, and MOXFQ scores for pain, walking and social capability were, respectively, 15.0° ± 2.1°, 26.1° ± 4.2°, (1.0 ± 0.5) points, 20.0(0, 30.0) points, (16.5 ± 13.2) points and 12.5(0, 18.8) points in the supine group, and 15.7° ± 1.6°, 27° ± 4.0°, (1.3 ± 0.7) points, 12.5(10.0, 30.0) points, (19.0 ± 11.5) points and 15.6(6.3, 25.0) points in the prone group, showing no significant differences ( P>0.05). The total incidence of complications was 8.3% (2/24) in the supine group and 3.3% (1/30) in the prone group, showing no significant difference either ( P>0.05). Conclusion:In the treatment of posterior pilon fractures, as the modified posteromedial approach combined with the anterolateral approach in the supine position is equivalent to the posteromedial and the posterolateral approaches in the prone position in terms of reduction quality, bone union time, functional outcomes and complications, it can be used as an alternative choice.

The Coronavirus disease 2019 (COVID-19) has spread globally. Although mixed liver impairment has been reported in COVID-19 patients, the association of liver injury caused by specific subtype especially chronic hepatitis B (CHB) with COVID-19 has not been elucidated. In this multi-center, retrospective, and observational cohort study, 109 CHB and 327 non-CHB patients with COVID-19 were propensity score matched at an approximate ratio of 3:1 on the basis of age, sex, and comorbidities. Demographic characteristics, laboratory examinations, disease severity, and clinical outcomes were compared. Furthermore, univariable and multivariable logistic and Cox regression models were used to explore the risk factors for disease severity and mortality, respectively. A higher proportion of CHB patients (30 of 109 (27.52%)) developed into severe status than non-CHB patients (17 of 327 (5.20%)). In addition to previously reported liver impairment markers, such as alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total bilirubin, we identified several novel risk factors including elevated lactate dehydrogenase (⩾ 245 U/L, hazard ratio (HR) = 8.639, 95% confidence interval (CI) = 2.528-29.523; P < 0.001) and coagulation-related biomarker D-dimer (⩾ 0.5 µg/mL, HR = 4.321, 95% CI = 1.443-12.939; P = 0.009) and decreased albumin (< 35 g/L, HR = 0.131, 95% CI = 0.048-0.361; P < 0.001) and albumin/globulin ratio (< 1.5, HR = 0.123, 95% CI = 0.017-0.918; P = 0.041). In conclusion, COVID-19 patients with CHB were more likely to develop into severe illness and die. The risk factors that we identified may be helpful for early clinical surveillance of critical progression.

Objective:To explore the relationship between input and output of occupational health funds, and to provide basis for relevant departments to make decisions.Methods:In September 2018, a state-owned iron ore in Hebei Province (mining history of more than 10 years, which can represent the general type of iron ore) was selected as the research object. Through the investigation and collection of enterprise general situation, occupational health input, loss and output related indicators, the iron mine occupational health expenditure input-output table and model were established, and the digital relationship between the investment and output was solved by MATLAB software.Results:The labor consumption in the departments of underground mining, open pit mining, crushing and rock discharging, transportation, tailings and mineral processing (taking labor wages as reference) were 756.46, 1.281.78, 987.61, 1 570.71, 50.956 and 18.9116 million yuan/year respectively. The output value of each sector is 11 207.19, 18 989.95, 15 176.40, 25 294.00, 7.704.94 and 280.1797 million yuan/year respectively. The ratio of health input to total output was 0.004 5, and the ratio of occupational health input to output was 1/0.046.Conclusion:The input-output table model of occupational health in iron mine can reflect the relationship between input and output of occupational health funds. The input situation of the coal mine is poor, and the input does not bring obvious occupational health benefits.
