Objective:To explore the protective mechanism of Xuebijing injection (referred to as Xuebijing) on sepsis-associated acute respiratory distress syndrome (ARDS).Methods:① Animal experiments: 100 mice were randomly(random number) divided into 4 groups, including sham operation (Sham) group, cecal ligation and puncture (CLP) group, CLP+low-dose Xuebijing (L-XBJ) group, and CLP+high-dose Xuebijing (H-XBJ) group. The survival rate, lung histological changes, lung wet/dry (W/D) ratio, cell count and protein concentration in bronchoalveolar lavage fluids (BALF), inflammatory factors levels in serum, oxidative stress indicators, cell apoptosis, and key proteins of HIF-1α/p38 MAPK/NF-κB signaling pathway were measured. ② Cell experiments: Mouse alveolar macrophages (MH-S) were cultured in vitro and divided into 6 groups, including control (Con) group, lipopolysaccharide (LPS) group, LPS+L-XBJ group, and LPS+H-XBJ group, LPS+H-XBJ+ dimethyloxallyl glycine (DMOG, HIF-1α activator) group, LPS+H-XBJ+ 2-methoxyestradiol (2ME2, HIF-1α inhibitor) group. The effects of Xuebijing on inflammatory factors, oxidative stress, and cell apoptosis and their relationship with HIF-1α/p38 MAPK/NF-κB signaling pathway were detected.Results:Xuebijing increased the survival rate of mice with sepsis-associated ARDS, relieved lung tissue damage [lung injury score: CLP group (8.778±0.588), CLP+L-XBJ group (5.833±0.310), and CLP+H-XBJ group (4.750±0.246)], alleviated lung W/D ratio, and decreased pneumonia cell infiltration and protein exudation (all P<0.05). Additionally, Xuebijing treatment also diminished the expression of inflammatory factors (TNF-α, IL-1β, and IL-6), intracellular reactive oxygen species (ROS) accumulation, malondialdehyde (MDA) formation, superoxide dismutase (SOD) depletion, and cell apoptosis in LPS-induced MH-S cells and CLP-induced sepsis-associated ARDS mice (all P<0.05). Furthermore, mechanistic investigation further clarified the effects of Xuebijing on inflammation, oxidative stress, and cell apoptosis through the HIF-1α/p38 MAPK/NF-κB signaling pathway. Conclusions:Xuebijing can exert anti-inflammatory, anti-oxidative, and anti-apoptotic effects by suppressing the HIF-1α/p38 MAPK/NF-κB signaling pathway, thereby conferring protection against sepsis-associated ARDS.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective:To evaluate the clinical effect of microbotox injection of botulinum toxin type A in improving the fine lines of lower eyelid skin and achieving the rejuvenation of the eye area.Methods:The clinical data of patients with mildly sagging lower eyelid skin and fine wrinkles admitted to Facial and Neck Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College; Deparment of Plastic and Cosmetic Surgery, Guangyuan Central Hospital; Department of Dermatology, People’s Hospital of Qingshen County; Department of Plastic and Cosmetic Surgery, Dujiangyan People’s Hospital; Devision of Women’s Healthcare, Panzhihua Maternal and Child Hospital; Chengdu Badachu Cosmetic Hospital from August 2022 to January 2023 were analyzed retrospectively. Using the microbotox injection method, the botulinum toxin type A with a diluted concentration of 8 U/ml was micro-injected into the dermis layer or between the dermis and the superficial muscle layer at an interval of 0.6 cm, and a single point injection of 0.2 U. The injection range was the anatomical distribution range of the orbicularis oculi muscle. After treatment, patients were followed up to investigate patient satisfaction, which was divided into very satisfied, satisfied, dissatisfied and very dissatisfied, and to calculate subjective satisfaction (percentage of the number of very satisfied and satisfied cases in the total number of cases). At the same time, a independent physician used the global aesthetic improvement scale (GAIS) to evaluate the effect based on the patient’s photos before treatment and during follow-up. 5 indicates as worse than before, 4 as no improvement, 3 as were slight improvement, 2 as moderate improvement, and 1 as significant improvement. SPSS 24.0 software was used for descriptive analysis of the data.Results:A total of 23 patients were enrolled, including 1 male and 22 females, aged (36.4±2.5) years old. The follow-up was 1-6 months, with an average of 1.4 months, and the subjective satisfaction of patients was 100% (23/23). The result of the independent physician evaluation were as follows: the overall cosmetic improvement score of the observers was 1.26±0.54, 100% (23/23) of the patients reached the standard of obvious or moderate improvement. In terms of complications, 2 patients presented local epidermis bruises after injection, who recovered within 1 week; 1 patient complained of pain after injection, which was significantly relieved 12 hours later. No ectropion, symblepharon, facial palsy, dry eyes, or other complications were observed.Conclusion:Application of botulinum toxin type A microbotox injection can improve periorbital wrinkles and improve skin texture at the same time, and the therapeutic effect is definite.

Transcranial magneto-acoustic electrical stimulation (TMAES) is a novel method of brain nerve regulation and research, which uses induction current generated by the coupling of ultrasound and magnetic field to regulate neural electrical activity in different brain regions. As the second special envoy of nerve signal, calcium plays a key role in nerve signal transmission. In order to investigate the effect of TMAES on prefrontal cortex electrical activity, 15 mice were divided into control group, ultrasound stimulation (TUS) group and TMAES group. The TMAES group received 2.6 W/cm ² and 0.3 T of magnetic induction intensity, the TUS group received only ultrasound stimulation, and the control group received no ultrasound and magnetic field for one week. The calcium ion concentration in the prefrontal cortex of mice was recorded in real time by optical fiber photometric detection technology. The new object recognition experiment was conducted to compare the behavioral differences and the time-frequency distribution of calcium signal in each group. The results showed that the mean value of calcium transient signal in the TMAES group was (4.84 ± 0.11)% within 10 s after the stimulation, which was higher than that in the TUS group (4.40 ± 0.10)% and the control group (4.22 ± 0.08)%, and the waveform of calcium transient signal was slower, suggesting that calcium metabolism was faster. The main energy band of the TMAES group was 0-20 Hz, that of the TUS group was 0-12 Hz and that of the control group was 0-8 Hz. The cognitive index was 0.71 in the TMAES group, 0.63 in the TUS group, and 0.58 in the control group, indicating that both ultrasonic and magneto-acoustic stimulation could improve the cognitive ability of mice, but the effect of the TMAES group was better than that of the TUS group. These results suggest that TMAES can change the calcium homeostasis of prefrontal cortex nerve clusters, regulate the discharge activity of prefrontal nerve clusters, and promote cognitive function. The results of this study provide data support and reference for further exploration of the deep neural mechanism of TMAES.
