Objective To explore the correlations between serum Mas-related G protein-coupled receptor X2 (MRGPRX2), interleukin (IL)-4, IL-5, IL-6, IL-13, IL-23 and IL-33 levels and chronic spontaneous urticaria (CSU). Methods The clinical characteristics and laboratory data from 55 patients with CSU and 21 healthy controls at Huashan Hospital, Fudan University from February 2021 to September 2023 were collected. The disease activity and severity of CSU patients were assessed. Serum level of MRGPRX2 was tested using enzyme-linked immunosorbent assay (ELISA), and levels of IL-4, IL-5, IL-6, IL-13, IL-23, and IL-33 were measured using Luminex multiplex assay in all subjects. Spearman correlation analysis was used to evaluate the correlations between biomarkers and other parameters in CSU patients, and logistic regression analysis was performed to identify factors influencing CSU. Results CSU patients exhibited significantly higher serum levels of MRGPRX2 (2.41[0, 11.51] ng/mL vs 0[0, 2.86] ng/mL, P=0.015) and IL-23 (0.09[0.04, 0.56] pg/mL vs 0.05[0.03, 0.08] pg/mL, P=0.033) than healthy controls. There was no difference in levels of other cytokines between the two groups. There was no difference in levels of MRGPRX2 and cytokines between severe and non-severe CSU patients. Correlation analysis showed that serum MRGPRX2 levels in CSU patients were positively correlated with IL-4 (r=0.345, P=0.010) and IL-6 (r=0.395, P=0.003) levels. Logistic regression analysis indicated that MRGPRX2≥0.055 ng/mL and IL-23≥0.135 pg/mL were independent risk factors for CSU (P<0.05). Conclusions Serum levels of MRGPRX2 and IL-23 in CSU patients are elevated, which may be involved in the pathogenesis of CSU.

Objective:To explore the efficacy of long intramedullary nails versus short intramedullary nails in the treatment of AO/OTA 31-A3 intertrochanteric fractures.Methods:A retrospective analysis was conducted on 60 patients with AO/OTA 31-A3 intertrochanteric femur fractures treated between March 2019 and August 2022. The patients were randomly divided into two groups (the long nail group and the short nail group). Thirty-four patients were treated with long intramedullary nails, including 16 males and 18 females, aged 68.41±17.84 years old (range 31-96 years). Twenty-six patients were treated with short intramedullary nails, including 13 males and 13 females, aged 72.23±13.97 years old (range 31-90 years). The causes of injury, fracture classification (AO/OTA classification), intraoperative blood loss, operation time, fracture healing time, imaging indexes (fracture reduction quality, postoperative neck trunk angle, and medial support), Harris score of the hip joint at the last follow-up, one-year mortality rates and complications were compared between the two groups.Results:The follow-up time was 24.26±6.67 months in the long nail group and 24.31±5.60 months in the short nail group, and the general information of the two groups were comparable. Between the long nail and short nail group, the intraoperative blood loss was 281.47±235.28 ml vs. 121.92±84.14 ml and the operation time was 110.44±24.63 min vs. 81.15±28.54 min with significant differences ( P<0.05). While the length of hospital stay was 12.35±4.81 d vs. 10.89±4.30 d, the good rate of fracture reduction was 55.9% vs. 61.53%, the fracture healing time was 120.44±16.43 d vs. 128.07±18.33 d, the presence rate of medial support was 67.6% vs. 79.4%, and the excellent rate of Harris score was 65.4% vs. 65.4% with no significant difference between the two groups ( P>0.05). One-year mortality rates was 5.3% vs. 7.1% and complications was 11.7% vs. 15.4% with no significant difference between the two groups ( P>0.05). Conclusion:Both long intramedullary nails and short intramedullary nails are effective in the treatment of AO/OTA 31-A3 intertrochanteric femur fractures. However, surgical time and intraoperative blood loss was less in the short nail group.

Objective:To evaluate the efficacy of perioperative analgesia with esketamine in the patients undergoing thoracoscopic surgery.Methods:A total of 90 patients of either sex, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective thoracoscopic lobectomy under general anesthesia, were divided into 3 groups ( n=30 each) by a random number table method: control group (C group) and different doses of esketamine groups (S 1 group, S 2 group). Before induction of anesthesia, esketamine 0.1 and 0.2 mg/kg were intravenously injected in S 1 group and S 2 group, respectively, while esketamine was not given in group C. Anesthesia was routinely induced in all the three groups. During anesthesia maintenance, esketamine 0.1 and 0.2 mg·kg -1·h -1 were intravenously infused in group S 1 and group S 2, respectively, and the remaining drugs used for anesthesia maintenance were the same in the three groups. Patient-controlled intravenous analgesia (PCIA) was used after operation, and PCIA solution contained sufentanil 2 μg/kg in group C, and esketamine 1 mg/kg was mixed on the basis as previously described in S 1 and S 2 groups. Aminotriol ketorolac was given as rescue analgesia to maintain numeric rating scale score at rest ≤3. The total amount of propofol and remifentanil during operation, effective pressing times of PCIA in postoperative 0-24 h and >24-48 h periods, and requirement for rescue analgesia were recorded. The occurrence of adverse reactions such as respiratory depression, nausea and vomiting, dizziness and salivation, and emergence time were recorded after surgery. The serum interleukin-6 (IL-6) concentration was measured by enzyme-linked immunosorbent assay at 30 min before and after surgery, and the malondialdehyde (MDA) concentration in serum was measured by thiobarbituric acid colorimetric analysis. The postoperative recovery was assessed using the 50-item quality of recovery scale at 1 and 2 days after surgery. The development of chronic pain was followed up by telephone within 1-3 months after surgery. Results:Compared with group C, the intraoperative consumption of remifentanil, effective pressing times of PCIA in postoperative 0-24 h and >24-48 h periods, rate of rescue analgesia, and postoperative serum IL-6 concentration were significantly decreased, and the 50-item quality of recovery scale score was increased in S 1 and S 2 groups, and the postoperative serum MDA concentration was significantly decreased in group S 2 ( P<0.05). Compared with group S 1, the consumption of intraoperative remifentanil was significantly decreased ( P<0.05), and no significant change was found in postoperative serum IL-6 and MDA concentrations in group S 2 ( P>0.05). Compared with group S 2, the postoperative emergence time was significantly shortened in S 1 and C groups ( P<0.05). There was no statistically significant difference in the intraoperative consumption of propofol, incidence of adverse effects and incidence of chronic pain among the three groups ( P>0.05). Conclusions:Esketamine for perioperative analgesia (dose before anesthesia induction 0.1 mg/kg, dose for maintenance of anesthesia 0.1 mg·kg -1·h -1, dose for postoperative PCIA 1 mg/kg) can raise the quality of analgesia and improve the quality of early postoperative recovery in the patients undergoing thoracoscopic lobectomy.
