[Application of machine learning models in predicting early stone-free rate after flexible ureteroscopic lithotripsy for renal stones].
To establish predictive models based on random forest and XGBoost machine learning algorithm and to investigate their value in predicting early stone-free rate (SFR) after flexible ureteroscopic lithotripsy (fURL) in patients with renal stones. ⋯ The predictive models based on random forest and XGBoost machine learning algorithm can predict postoperative early stone status after fURL for renal stones accurately, which will facilitate preoperative evaluation and clinical decision-making. Stone volume, mean stone density, maximal stone density and BMI may be the important predictive factors affecting early SFR after fURL for renal stones.

[Altered serum cytokine expression profile in systemic sclerosis and its regulatory mechanisms].
To analyze the expression profile of serum cytokines in patients with systemic sclerosis (SSc) and explore its possible regulatory mechanisms. ⋯ There were different cytokines expression profiles in the serum of SSc patients, and the altered cytokines were correlected with the degree of skin damage and pulmonary fibrosis. Many cytokines were regulated by methylation.

Meta Analysis[Proximal femoral nails antirotation and dynamic hip screws for fixation of unstable intertrochanteric fractures of femur: A meta-analysis].
To evaluate the efficacy and safety of proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) for unstable intertrochanteric fractures using meta-analysis. ⋯ Current published evidence supports the superiority of PFNA to DHS for unstable intertrochanteric fractures in terms of clinical efficacy. The conclusion was limited because of the relatively low quality of evidence with low strength of confidence. Large scale and high-quality randomized controlled trials are required to validate the safety of PFNA and DHS for unstable intertrochanteric fractures.

[Application of ultrasound-guided hip joint drug injection in the postoperative rehabilitation of arthroscopie repair of acetabular labral tears].
To explore the clinical application of ultrasound-guided hip joint drug injection in the postoperative rehabilitation of arthroscopie repair of acetabular labral tears. ⋯ For patients with hip pain and limitations after arthroscopie repair of acetabular labral tears, ultrasound-guided drug injection can effectively reduce hip pain, improve hip activity, and promote hip functional reconstruction.

Case Reports[Exogenous lipoid pneumonia induced by long-term usage of compound menthol nasal drops: a case report].
Here we reported a case of exogenous lipoid pneumonia from Peking University Third Hospital. A 62-year-old male presented with chronic cough and expectoration for 8 years, without chest pain, hemoptysis or short of breath. He was an ex-smoker. ⋯ Given these findings, it emerged that the patient was taking twice daily inhalations of a compound menthol nasal drops (essential oil of camphor, menthol and liquid paraffin) for his chronic rhinitis sicca for at least 10 years. Then he discontinued oil nasal sprays and showed gradual improvement 3 months later without intensive treatment. The presenting case report emphasizes the fact that chronic inhalation of nasal sprays and decongestants containing mineral oils was a cause of exogenous lipoid pneumonia, and clinicians should bear it in mind.
