OBJECTIVE: To construct a predictive model for the reduction in methadone maintenance treatment (MMT) and evaluate the effects of different interventions and other clinical factors on methadone reduction using Shapley additive explanations (SHAP). METHODS: Two clinical trials of acupuncture for methadone reduction in MMT patients were analyzed, and the baseline data, MMT related information, intervention measures, the data related to dose-reduction outcomes were collected. The predictive model was constructed by means of 6 machine learning algorithms including support vector machine (SVM), K-nearest neighbors (KNN), logistic regression (LR), Naive Bayes (NB), random forest (RF) and categorical-boosting (CatBoost), and 2 integration methods, blending-ensemble method (Blending) and Stacking-ensemble method (Stacking). SHAP was employed for the interpretability analysis of the optimal model. RESULTS: A total of 251 MMT patients were included, 128 cases in the acupuncture group and 123 cases in the non-acupuncture group. CatBoost and Stacking performed optimally in the test set. CatBoost obtained an accuracy of 0.780 0±0.060 8, a precision of 0.500 0±0.120 0, a recall of 0.818 2±0.140 2, F1 score of 0.620 7±0.114 0, and receiver operating characteristic-area under curve (ROC-AUC) of 0.857 8±0.140 2 for the subjects. In MMT patients with acupuncture as an adjunctive therapy, the top 5 important features for methadone reduction, included intervention measures, body mass index (BMI), the duration of MMT, the history of opioid use and occupation; and SHAP values were 1.25, 0.36, 0.21, 0.19 and 0.12, respectively. The SHAP feature dependence plot showed that BMI, MMT duration and the history of opioid use presented a nonlinear negative correlation with the reduction effect. CONCLUSION In acupuncture as adjunctive therapy for methadone reduction, the clinical factors should be considered comprehensively; and the interpretable predictive model provides a scientific basis for it, which is conducive to the improvement of clinical strategy of acupuncture for methadone reduction and the development of personalized reduction scheme.

Objective To investigate the clinical efficacy of Qingpeng Ointment(composed of Aconiti Penduli Radix,,Benzoinum,Artificial Moschus,Oxytropis Falcatae Herba,Rhei Pumili Radix Et Rhizoma,Fructus Phyllanthi,etc.)combined with Secukinumab Injection in treating patients with plaque psoriasis of blood stasis syndrome type.Methods From October 2022 to March 2024,a total of 86 patients diagnosed as plaque psoriasis of blood stasis syndrome type from the Department of Dermatology,Chuzhou First People's Hospital Affiliated to Anhui Medical University were enrolled.The patients were equally randomized into an observation group and a control group using a simplified randomization method,with 43 cases in each group.The control group received subcutaneous injection of Secukinumab Injection,while the observation group received additional topical application of Qingpeng Ointment based on the regimen for the control group.Both groups were treated for 3 months.The following parameters in both groups were assessed before and after treatment:the severity scores of skin lesion(including erythema,infiltration,and scale),traditional Chinese medicine(TCM)syndrome scores,quality of life scores,serum levels of inflammatory factors[interleukin 17A(IL-17A),interleukin 10(IL-10),vascular endothelial growth factor(VEGF)],and leukocyte p38 mitogen-activated protein kinase(MAPK)expression levels(including staining intensity scores and positive cell percentage scores).After treatment,the clinical efficacy and total incidence of adverse reactions were compared between the two groups.Results(1)After 3 months of treatment,the markedly-effective rate was 81.40%(35/43)in the observation group versus 58.14%(25/43)in the control group.The intergroup comparison showed significantly superior clinical efficacy in the observation group(χ2=8.378,P＜0.05).(2)After treatment,both groups exhibited significant reductions in the severity scores of skin lesion(including erythema,infiltration,and scale),TCM syndrome scores,quality of life scores,serum levels of inflammatory factors(IL-17A,IL-10,and VEGF),and expression levels of p38 MAPK in leukocytes(including staining intensity scores and positive cell percentage scores)(all P＜0.05),and the observation group demonstrated significantly greater reductions in all parameters than the control group(P＜0.05).(3)The total incidence of adverse reactions was 6.98%(3/43)in the observation group versus 13.95%(6/43)in the control group,showing no statistically significant intergroup difference(χ2=1.117,P＞0.05),and all adverse reactions in both groups resolved spontaneously within 1-2 day(s)after treatment.Conclusion Qingpeng Ointment combined with Secukinumab Injection demonstrates significant clinical efficacy in treating plaque psoriasis with blood stasis syndrome,and is effective on alleviating skin lesions and exerting anti-inflammatory effects through the suppression of leukocyte p38 MAPK expression.

Objective:To explore the safety and efficacy of intraosseous regional administration (IORA) of vancomycin for preventing infection in primary total knee arthroplasty (TKA).Methods:A total of 124 patients with knee osteoarthritis undergoing TKA between February 2024 and May 2024 at nine hospitals were enrolled. Preoperative infection prophylaxis involved either IORA (0.5 g vancomycin administered via intraosseous regional infusion before incision) or intravenous infusion (1 g vancomycin via peripheral vein). The IORA group included 15 males and 47 females with a median age of 66.5 years (range, 60.0-70.0 years), while the intravenous group included 14 males and 48 females with a median age of 66.0 years (range, 61.8-70.3 years) years. Intraoperative samples were collected including fat and synovium tissues after incision, before prosthesis placement, and after tourniquet release; distal femoral cancellous bone during femoral osteotomy; proximal tibial cancellous bone during tibial osteotomy; proximal intercondylar cancellous bone before prosthesis placement; and peripheral blood from non-infused arms at surgery initiation and after tourniquet release. Vancomycin concentrations were measured using liquid chromatography-tandem mass spectrometry. Vital sign changes were recorded from admission to 5~10 minutes post-IORA (IORA group) or post-incision (intravenous group). Follow-ups were conducted on postoperative day 1 and 3, and at 1 and 3 months, to document complications including IORA-related adverse events, periprosthetic joint infections, surgical site infections, red man syndrome, acute kidney injury, deep vein thrombosis and so on.Results:Vancomycin concentrations in bone, fat, and synovial tissue samples were significantly higher in the IORA group than in the intravenous group ( P<0.05), while vancomycin concentrations in blood samples were significantly lower in the IORA group than in the intravenous group ( P<0.05). Only 7.3%(41/558) of tissue samples in the IORA group had vancomycin concentrations below 2.0 μg/g (the minimum inhibitory concentration of vancomycin against coagulase-negative staphylococcus), compared to 59.3%(331/558) in the intravenous group (χ 2=11.285, P<0.001). In the intravenous group, 16.9%(21/124) of blood samples had vancomycin concentrations exceeding 15.0 mg/L (the threshold associated with a significantly increased risk of nephrotoxicity), while all concentrations in the IORA group were below this threshold, the difference was statistically significant (χ 2=22.943, P<0.001). There were no statistically significant difference ( P>0.05) in vital signs changes before and after vancomycin administration between the two groups. Two patients in the intravenous group experienced incision exudate, while no other related complications occurred in either group. Conclusions:Compared to the traditional intravenous infusion of 1 g vancomycin, intraosseous injection of a low dose (0.5 g) of vancomycin achieves higher local tissue concentrations in the knee joint with a lower incidence of adverse reactions and is safe for infection prophylaxis. Despite guidelines not recommending the routine use of vancomycin for preventing infection after primary TKA, intraosseous injection of 0.5 g vancomycin may be considered intraoperatively for primary TKA in the following scenarios: patients in medical institutions with a high prevalence of methicillin-resistant staphylococcus aureus (MRSA) infections, patients with potential preoperative MRSA colonization, or patients with cephalosporin allergy.

Cerebral small vessel disease(CSVD)refers to a series of clinical imaging pathological syndromes caused by various etiologies affecting cerebral small vessels,which have the characteristics of insidious onset,high inci-dence and easy recurrence.Insulin resistance(IR)is a decrease in the body's sensitivity to insulin.In recent years,more and more studies have confirmed that IR is associated with the occurrence and development of imaging features of CS-VD,but the mechanism is still unclear.This article reviews the relationship between IR and cerebral small vessel disease and its possible mechanism,in order to provide reference for the prevention and treatment of cerebral small vessel disease.

Objective:To evaluate the clinical efficacy of single-stage total hip arthroplasty (THA) combined with intra-articular antibiotic injection in managing postoperative infections following internal fixation of hip fractures.Methods:A retrospective analysis was conducted on 25 patients who underwent single-stage THA for infection following internal fixation of hip fractures from January 2013 to January 2021 at the Department of Joint Surgery, First Affiliated Hospital of Xinjiang Medical University. The cohort comprised 15 males and 10 females, with an average age of 61.52±13.06 years (range, 32-89 years) and an average body mass index of 24.04±3.84 kg/m 2 (range, 18-34 kg/m 2). The fractures included 13 femoral neck fractures, 6 intertrochanteric fractures, 4 acetabular fractures, 1 proximal femoral fracture, and 1 combined acetabular and intertrochanteric fracture. Preoperative joint cavity puncture or intraoperative joint fluid extraction, biochemical analysis, microbial culture, and drug sensitivity tests were performed. During surgery, infected internal fixation devices were removed, and hip prostheses were implanted following thorough debridement. Postoperatively, patients received intravenous and intra-articular sensitive antibiotics based on bacterial culture and drug sensitivity results. Joint stability was evaluated according to the Engh standard, and hip function was assessed using the Harris score. Results:Microbial cultures were positive in 12 cases, identifying Staphylococcus epidermidis (4 cases), Staphylococcus aureus (2 cases), Escherichia coli (2 cases), Enterobacter cloacae (1 case), Pseudomonas aeruginosa (1 case), Corynebacterium striatum (1 case), and a mixed infection of Staphylococcus epidermidis and Enterococcus faecalis (1 case). All 25 patients were followed for an average of 56.64±26.38 months (range, 24-123 months). Intravenous and intra-articular antibiotic treatment was administered to all patients. One case experienced sinus tract formation and pus discharge on the 20th postoperative day, diagnosed as periprosthetic infection, resulting in treatment failure, yielding an infection control rate of 96% (24/25). All patients demonstrated stable prosthesis fixation with no subsidence, loosening, or osteolysis. At the final follow-up, the Harris hip score improved significantly from a preoperative score of 26.69±13.47 to 92.30±5.60 ( t=22.882, P<0.001). Complications included 2 cases of hip dislocation, 2 cases of deep venous thrombosis in the lower extremities, 1 case of poor wound healing, and 1 case of periprosthetic fracture. Conclusion:Single-stage THA combined with intra-articular antibiotic injection is effective in controlling infections following internal fixation of hip fractures. This approach not only achieves a high infection control rate but also reconstructs hip joint function, resulting in satisfactory postoperative outcomes.
