Background:The burden of Crohn's disease(CD)is rising globally,and the efficacy and safety of ustekinumab(UST)in treatment of CD need to be further verified.Aims:To assess the short-term efficacy and safety of UST in CD patients.Methods:A single-center retrospective observational study was conducted in the First Affiliated Hospital of Kunming Medical University.The clinical data of CD patients treated with UST from January 2020 to December 2023 were analyzed retrospectively.The clinical activity and endoscopic severity of the disease were assessed using Crohn's disease activity index(CDAI)and simple endoscopic score for Crohn's disease(SES-CD),respectively.The primary outcomes were clinical response(CDAI score decreased≥70 points,or CDAI score decreased<70 points but the total score<150)and clinical remission(CDAI score<150),while the secondary outcomes included endoscopic response(SES-CD decreased≥50%),endoscopic remission(SES-CD≤2),changes of inflammatory and nutritional indicators,and the adverse events.Results:Twenty-seven CD patients were included,of which,16 were males,and 11 were females,with median disease duration of 3.00 years.After treatment with UST,the median CDAI score decreased from 213.00(178.83,302.98)at baseline to 129.83(89.67,151.33)at week 16/20 and 95.07(67.45,178.34)at week 32(all P<0.017).The clinical response rate and remission rate at week 16/20 were 92.6%and 70.4%,respectively,and those at week 32 were 95.5%and 72.7%,respectively.When patients were stratified as biologic na?ve and exposure,or as with and without dose optimization,no significant differences were found in clinical response and remission rates among various subgroups.Seventeen patients reviewed endoscopy at week 16/20,the SES-CD decreased significantly from baseline(5.47±4.53 vs.9.88±4.58,P<0.05),with the endoscopic response rate and remission rate of 35.3%and 23.5%,respectively.C-reactive protein decreased significantly from baseline at week 16/20 and week 32 of treatment(all P<0.017),while the platelet count,hemoglobin,albumin and body mass index only showed insignificant improving trends.No serious adverse events were observed during the medication period.Conclusions:UST can improve the clinical symptoms,endoscopic manifestations,and systemic inflammation effectively in CD patients in short-term follow-up,and represents a good safety profile.

Objective To compare the sedative effect and safety of remimazolam and midazolam in synchronous electrical cardioversion in patients with atrial fibrillation.Methods Thirty-two patients with at-rial fibrillation receiving synchronous electrical cardioversion from January 2021 to December 2022 were en-rolled,22 males and 10 females,aged 18-80 years,BMI 20-30 kg/m2,ASA physical status Ⅱ or Ⅲ.The patients were randomly divided into two groups using random number table method:remimazolam group and midazolam group,16 patients in each group.The remimazolam group was sedated with 0.2 mg/kg of intra-venous remimazolam,and the midazolam group was sedated with 0.025 mg/kg of midazolam intravenously,and the drug injection time in both groups was 1 min.The anesthesia onset time,awakening time,and ori-entation recovery time were recorded.SBP,DBP,and SpO2 were recorded before anesthesia induction(T,),when the eyelash reflex was absent(T2),after the completion of electrical cardioversion(T3),and at the time of awakening(T4).Neurobehavioral cognitive state examination(NCSE)was performed 5 mi-nutes after the patients were awake,including language ability,structural ability,memory,calculation abil-ity and reasoning ability,and the pass rate of each ability test was calculated.The occurrence of adverse re-actions during surgery(body movement,apnea)and within 12 hours after surgery(nausea,vomiting,and chest pain)was recorded.Results Compared with the midazolam group,the anesthesia onset time,awak-ening time,and orientation recovery time in the remimazolam group were significantly shortened(P＜0.05).There was no significant difference in SBP,DBP,and Sp02 between the two groups at different time points.Compared with the midazolam group,the pass rate of the reasoning ability test was higher in the remimazolam group 5 minutes after awakening(P＜0.05).There was no significant difference in the inci-dence of adverse reactions between the two groups.Conclusion Compared with midazolam,remimazolam has faster onset of sedation,faster awakening,faster recovery of orientation in synchronous electrical cardio-version of atrial fibrillation,and faster recovery of reasoning ability in NCSE after synchronous electrical car-dioversion.

Purpose: This study was performed to compare the therapeutic efficacy of endoscopic surgery and open surgery and their effects on postoperative blood coagulation state in patients with thyroid cancer, and to provide evidence for the prevention measurement of thrombosis in the perioperative period. Methods: One hundred patients with thyroid cancer who received treatment in our hospital from January 2021 to December 2021, were randomly divided into an endoscopic group and an open surgery group, with 50 patients in each group. The patients in the open surgery group were treated by traditional open surgery, while patients in the endoscopic group accepted endoscopic surgery. The clinically therapeutic effect and blood coagulation of the 2 groups were compared. Results: Intraoperative blood loss and length of hospital stay were lower, and operative time was longer in the endoscopic group than in the open surgery group (P < 0.05). The 24-hour postoperative fibrinogen and D-dimer levels were higher in both groups than in the preoperative period, while PT was shorter (P < 0.05). There were no significant differences in postoperative complications and follow-up between the 2 groups (P > 0.05), but the incidence of complications, postoperative metastases, and thrombosis was relatively low in the endoscopic group. Conclusion In the treatment of patients with thyroid cancer, endoscopic surgery has the advantages of less blood loss, fewer complications, and so on. Endoscopic and open surgery can lead to a hypercoagulable state, but the effect of endoscopic surgery is better than that of open surgery.

OBJECTIVE: To investigate the effects of autophagy on osteogenic differentiation of stem cells from the apical papilla (SCAPs) in the presence of tumor necrosis factor- (TNF-) stimulation . METHODS: SCAPs treated with TNF- (0, 5, and 10 ng/mL) with or without 5 mmol/L 3-MA were examined for the expression of autophagy marker LC3-Ⅱ using Western blotting. The cells were transfected with GFP-LC3 plasmid and fluorescence microscopy was used for quantitative analysis of intracellular GFP-LC3; AO staining was used to detect the acidic vesicles in the cells. The cell viability was assessed with CCK-8 assays and the cell apoptosis rate was analyzed using flow cytometry. The cells treated with TNF- or with TNF- and 3-MA were cultured in osteogenic differentiation medium for 3 to 14 days, and real- time PCR was used to detect the mRNA expressions of osteogenesis-related genes (ALP, BSP, and OCN) for evaluating the cell differentiation. RESULTS: TNF- induced activation of autophagy in cultured SCAPs. Pharmacological inhibition of TNF--induced autophagy by 3-MA significantly decreased the cell viability and increased the apoptosis rate of SCAPs ( < 0.05). Compared with the cells treated with TNF- alone, the cells treated with both TNF- and 3-MA exhibited decreased expressions of the ALP and BSP mRNA on days 3, 7 and 14 during osteogenic induction ( < 0.05) and decreased expression of OCN mRNA on days 3 and 7 during the induction ( < 0.05). CONCLUSIONS Autophagy may play an important role during the osteogenic differentiation of SCAPs in the presence of TNF- stimulation.
