BACKGROUND: Preclinical studies have indicated that Angong Niuhuang Pills (ANP) reduce cerebral infarct and edema volumes. This study aimed to investigate whether ANP safely reduces cerebral infarct and edema volumes in patients with moderate to severe acute ischemic stroke. METHODS: This randomized, double-blind, placebo-controlled pilot trial included patients with acute ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores ranging from 10 to 20 in 17 centers in China between April 2021 and July 2022. Patients were allocated within 36 h after onset via block randomization to receive ANP or placebo (3 g/day for 5 days). The primary outcomes were changes in cerebral infarct and edema volumes after 14 days of treatment. The primary safety outcome was severe adverse events (SAEs) for 90 days. RESULTS: There were 57 and 60 patients finally included in the ANP and placebo groups, respectively for modified intention-to-treat analysis. The median age was 66.0 years, and the median NIHSS score at baseline was 12.0. The changes in cerebral infarct volume at day 14 were 0.3 mL and 0.4 mL in the ANP and placebo groups, respectively (median difference: -7.1 mL; interquartile range [IQR]: -18.3 to 2.3 mL, P = 0.30). The changes in cerebral edema volume of the ANP and placebo groups on day 14 were 11.4 mL and 4.0 mL, respectively ( median difference: 3.0 mL, IQR: -1.3 to 9.9 mL, P = 0.15). The rates of SAE within 90 days were similar in the ANP (3/57, 5%) and placebo (7/60, 12%) groups ( P = 0.36). Changes in serum mercury and arsenic concentrations were comparable. In patients with large artery atherosclerosis, ANP reduced the cerebral infarct volume at 14 days (median difference: -12.3 mL; IQR: -27.7 to -0.3 mL, P = 0.03). CONCLUSIONS: ANP showed a similar safety profile to placebo and non-significant tendency to reduce cerebral infarct volume in patients with moderate-to-severe stroke. Further studies are warranted to assess the efficacy of ANP in reducing cerebral infarcts and improving clinical prognosis. TRAIL REGISTRATION Clinicaltrials.gov , No. NCT04475328.

Objective:To investigate the efficacy and safety of fat suction combined with bipolar radiofrequency on face and neck rejuvenation.Methods:A total of 115 patients with face and neck fat deposits and skin laxity underwent fat suction combined with bipolar radiofrequency between December 2021 and October 2022 by the same surgeon in Changsha My Like Medical Cosmetology Hospital. There were 3 men and 112 women in this research. The mean age was 36.1 years (range, 26-55 years) and the mean body mass index was 21.4 (range, 16.8-27.7 kg/cm 2). Postoperative patient satisfaction surveys were conducted and 2 independent doctors evaluated clinical effect with preoperative and postoperative photographs at 3-6 months postoperatively. Results:The mean amount of fat aspirated was 44.5 ml (range, 10-92 ml) and the mean energy delivered was 4.5 kJ (range, 2.1-8.9 ml). 88.7% of patients were satisfied with their postoperative effect (102/115 patients). 92.2% of doctors were satisfied with the postoperative effect (106/115 patients). Four out of 115 patients (3.5%) developed irregularity by fat suction.Conclusions:Fat suction combined with bipolar radiofrequency can effectively reduce the fat accumulation of facial and neck and significantly improve skin relaxation. It is an effective method to rejuvenate facial and neck.

Patients with intracranial hemorrhage and indications of antithrombotic therapy are common in clinical practice. However, whether and when to start anticoagulant or antiplatelet therapy after intracranial hemorrhage are still debatable. Clinicians are posed with huge challenges without available guidelines. Through reviewing relevant literature, this article analyzed the risks of thromboembolism and hemorrhage recurrence after initiation of anticoagulant or antiplatelet therapy in patients with intracranial hemorrhage due to various etiologies. This article also presented the initiation time and specific antithrombotic plan in current clinical practice, aiming to propose references for clinicians.

Objective To observe the effect of transplantation of telomerase immortalized human neural progenitor cells to acute injured canine spinal cord by using MR diffusion tensor imaging (DTI).Methods Telomerase immortalized human neural progenitor cells with expression of green fluorescent protein were prepared for transplantation. Eight adult canines with left spinal cord hemisection at the level of T13 were examined by MR diffusion tensor imaging four times sequentially: prior to injury, one week after injury, one week after transplantation (two weeks after injury), and four weeks after transplantation. Results The ADC values of the injured spinal cord were (1.00?0.15)?10 -3 mm2/s, (1.65?0.45)?10 -3 mm2/s, (1.44?0.48)?10 -3 mm2/s, and (1.43?0.26) ?10 -3 mm2/s, respectively. There was statistically significant difference between the data obtained at different times (F=6.038, P=0.005). The FA values of the injured spinal cord were 0.59?0.11, 0.30?0.17, 0.36?0.25, and 0.34?0.11, respectively. There was also statistically significant difference between the data obtained at different times ( F=5.221,P=0.009). The ADC values of the intact spinal cord were (1.01?0.17)?10 -3 mm2/s, (1.32?0.06)?10 -3 mm2/s, (1.10?0.24)?10 -3 mm2/s, and (1.14?0.22) ?10 -3 mm2/s, respectively. There was no statistically significant difference between the data obtained at different times ( F=1.303,P=0.306). The FA values of the intact spinal cord were 0.60?0.09, 0.38?0.25, 0.46?0.15, and 0.50?0.21, respectively. There was also no statistically significant difference between the data obtained at different times (F=2.797,P=0.072).Conclusion DTI can provide useful information for spinal cord injury and regeneration in experimental spinal cord injury.
