Objective To observe the effect of ultrasound-guided iliopsoas plane block(IPB)on the quality of postoperative recovery in patients undergoing hip arthroplasty.Methods Sixty patients who underwent hip arthroplasty were selected,37 males and 23 females,aged 40-79 years,BMI 18-30 kg/m2,ASA physical status Ⅰ-Ⅲ.The patients were divided into two groups by random number table method:the iliopsoas plane block group(group IPB)and the femoral nerve block(FNB)group(group FNB),30 pa-tients in each group.Before anesthesia induction,IPB was performed with 0.5%ropivacaine 10 ml and lat-eral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group IPB.And FNB was performed with 0.5%ropivacaine 10 ml and lateral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group FNB.The dosages of propofol,remifentanil,and cis-atracurium during operation were recorded.The quality of recovery-15(QoR-15)scale was evaluated preoperatively and postoperatively 1 day,2 and 3 days.The max VAS(VASmax)pain score and manual muscle test(MMT)score of quadri-ceps muscle were recorded 12,24,and 48 hours after surgery.The time of getting out of bed for the first time,opioid dosage,and patient satisfaction were recorded.The incidence of nerve injury,vascular injury,puncture site infection,and local anesthetic poisoning were recorded.The postoperative complications of diz-ziness,nausea and vomiting,deep vein thromboses,and elirium were also recorded.Results There was no significant difference in the dosage of propofol,remifentanil,and cis-atracurium between the two groups.Compared with group FNB,the QoR-15 scale score in group IPB was significantly higher 1 day,2 and 3 days after operation(P＜0.05).Compared with group FNB,the MMT scores of quadriceps muscle was sig-nificantly higher in group IPB 12 and 24 hours after surgery(P＜0.05),and the first time of getting out of bed was shortened in group IPB(P＜0.05).However,there were no significant differences in the VASmax pain score,MMT score of quadriceps muscle 48 hours after surgery,opioid dosage,and patient satisfaction between the two groups.No nerve block related complications were found in both groups.There were no sig-nificant differences in postoperative complications between the two groups.Conclusion The iliopsoas plane block can improve the quality of postoperative recovery and accelerate the recovery of patients with hip re-placement,and the effect is better than that of femoral nerve block.

Objective:To investigate the efficacy of transcatheter arterial embolization (TAE) in treating postoperative hemorrhage in the gallbladder-pancreas-duodenum(GPD) region.Methods:The clinical data of 39 patients with postoperative hemorrhage in the GPD region who underwent digital subtraction angiography (DSA) examination in Peking Union Medical College Hospital from July 2018 to August 2022 were analyzed retrospectively, clinical regression was compared between TAE-treated and non-TAE-treated patients, and the concordance between DSA and enhanced CT for bleeding indications was analyzed using the Kappa test.Results:Among 39 patients, DSA examination suggested bleeding in 26 patients (66.7%), which were gastroduodenal artery hemorrhage in 4 cases, common hepatic artery and branches in 6 categories, superior mesenteric artery and branches in 6 cases, pancreaticoduodenal artery and branches in 4 cases, pancreatic aorta in 3 cases, splenic artery in 2 cases, and gastric left artery in 1 case. Positive DSA signs manifested as contrast spillage alone in 18 cases (69.2%), pseudoaneurysm alone in 7 cases (26.9%), and pseudoaneurysm with contrast spillage in 1 case (3.8%). 26 patients underwent TAE with a technical success rate of 96.2% (25/26), a clinical success rate of 88.5% (23/26) and a rebleeding rate of 7.7% (2/26). 13 patients didn't undergo TAE and the rebleeding rate was 30.8%(4/13). 14 patients underwent enhanced CT in the same period of DSA, showed low concordance with DSA in determining the presence or absence of bleeding, with a Kappa value of 0.462.Conclusions:TAE is a safe and effective treatment for postoperative hemorrhage in the GPD region. Patients without TAE treated should be alert for rebleeding. When postoperative hemorrhage is suspected, the consistency between enhanced CT and DSA examination results is limited, and DSA examination should be preferred.

Objective To observe the effect of opioid-free anesthesia with esketamine and ciprofol for the elderly underwent colonoscopy.Methods 160 elderly patients underwent colonoscopy were included in this study.Those patients were assigned to esketamine combined with ciprofol group(group E,n = 80)and sufentanil combined with ciprofol(group S,n = 80).Patients were intravenously injected respectively with esketamine 0.2 mg/kg in group E and sufentanil 0.1 μg/kg in group S.Then,all the patients were intravenously injected with ciprofol(0.2 mg/kg).Mean arterial pressure(MAP),heart rate(HR)and percutaneous arterial oxygen saturation(SpO2)were recorded before injection of test drug(T0),when modified observer's assessment of alertness/sedation(MOAA/S)score was 0 points(T1),when colonoscopy through hepatic flexure(T2)and colonoscopy was removed after examination(T3).The induction time of anesthesia,time of fully awake,rate of successful anesthesia,additional dose of ciprofol,satisfaction score and incidence of adverse events were recorded.Results Compared with T0,MAP at T1,T2 and T3 in two groups was decreased,HR at T1 in group E,HR at T1,T2 and T3 in group S and SpO2 at T1 and T2 in group S were decreased,the differences were statistically significant(P<0.05).Compared with T1,MAP and HR at T2 in two groups were increased,the differences were statistically significant(P<0.05).Compared with group E,MAP in group S at T1,T2 and T3,HR and SpO2 at T1 and T2 in group E were decreased,the differences were statistically significant(P<0.05).Compared with the group E,the additional dosage of ciprofol,the incidence of hypoxemia and hypotension were increased,the satisfaction of anesthesiologists was decreased in group S,the differences were statistically significant(P<0.05).Conclusion For opioid-free anesthesia,esketamine is feasible for colonoscopy anesthesia in elderly patient,and the incidence of hypoxemia and hypotension is low.

Objective To observe CT and MRI manifestations of lipofibromatosis(LPF)in children.Methods Data of 16 children with LPF confirmed by pathology were retrospectively analyzed,and CT and MRI manifestations of lesions were observed.Results Among 16 cases,lesions with clear boundary were found in 4 cases but with unclear boundary in 12 cases,shaped regularly in 6 cases but irregularly in 10 cases,with incomplete capsule in 2 cases but without capsule in 14 cases.Fat predominant type lesions were detected in 6 cases,mainly characterized by scattered fibrous bands in the center or cloud like soft tissue density/signal on one side of lesion,without obvious boundary.Fibrous dominant type lesions were noticed in 8 cases,mainly present as loose morphology,multiple fibrous bands extending to surrounding area,with scattered cystic fat density/signal within the lesion.Balanced type LPF lesion was observed in 2 cases,mainly manifestated as regular shape mixed density/signal lesion with clear boundary.Among 12 cases who underwent enhanced scanning,mild progressive enhancement in the non-fat area were observed in 7 cases,obvious peripheral enhancement but not obvious central enhancement was found in 2 case,obvious homogeneous enhancement was noticed in 1 case,while no obvious enhancement was found in 2 cases.No obvious calcification,cystic changes nor bone destruction was detected.Conclusion CT and MRI manifestations of LPF included subcutaneous fat containing density/signal,often composed mainly of adipocytes or fibrous components,with mild progressive enhancement or significant enhancement,without obvious capsule,calcification,cystic changes nor bone destruction.

Objective:To analyze the influencing factors of clozapine plasma concentration in patients with mental disorders after oral administration, so as to provide reference for individualized treatment.Methods:Retrospective analysis was made on 221 inpatient reports of Clozapine blood concentration monitoring in the Therapeutic Drug Monitoring Laboratory (TDM) of the Pharmacy Department of the Chaohu Hospital Affiliated to Anhui Medical University from January to October 2021, and information such as patient gender, age, body mass index (BMI), smoking history, clozapine dose, combined drug use and blood concentration monitoring results were collected; Single factor analysis of variance and binary logistic regression were used to analyze the monitoring results of clozapine blood concentration in patients with mental disorders and its influencing factors.Results:Among 221 monitoring reports, 74 cases (normal concentration group) had clozapine plasma concentration within the effective plasma concentration range (350-600 ng/ml), 103 cases (low concentration group) were lower than the effective plasma concentration range (<350 ng/ml), and 44 cases (high concentration group) were higher than the effective plasma concentration range (>600 ng/ml). The results of single factor analysis of variance showed that there were statistically significant differences in daily dose of clozapine, standard dose, smoking history, course of disease, and abnormal liver function of patients in different blood concentration groups of clozapine (all P<0.05). The most frequently used antipsychotic drugs in 221 patients with clozapine were sodium valproate, amisulpride, aripiprazole and lithium carbonate in turn. The proportion of clozapine combined with ≥2 antipsychotics in the normal concentration group was higher than that in the low concentration group and the high concentration group, and the difference was statistically significant ( P<0.05). The results of binary logistic regression analysis showed that the combination of one antipsychotic drug and ≥ two antipsychotic drugs might help the blood concentration of clozapine in patients with mental disorders reach the target concentration (350-600 ng/ml), and the combination of two drugs was more beneficial [ OR(95% CI): 1.795(0.753-4.282)], with a statistically significant difference ( P<0.05). Conclusions:Clozapine plasma concentration varies greatly among individuals, and the therapeutic window is narrow. It is necessary to adjust the dosage in combination with the basic information and clinical information of patients, and regularly monitor the plasma concentration, so as to achieve the safety and effectiveness of individualized drug use.

Objective:To investigate the levels of serum pyrolysis-related factors cysteine protease-1 (caspase-1) and interleukin-18 (IL-18) in patients with gestational diabetes mellitus (GDM) and their relationship with insulin resistance (IR) .Methods:A total of 102 GDM patients admitted to Kaifeng Traditional Chinese Medicine Hospital from Apr. 2019 to Mar. 2021 were selected as the GDM group, and 102 healthy pregnant women undergoing obstetric examination in the same period were included as the normal group. The age, gestational week, fasting insulin (FINS) , pre-pregnancy body mass index (BMI) , triglycerides (TG) , fasting blood glucose (FBG) , total cholesterol (TC) , and homeostatic model insulin resistance index (HOMA-IR) and other materials were compared between the GDM group and the normal group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum caspase-1 and IL-18; Pearson method was used to analyze the correlation between serum caspase-1 and IL-18 levels and HOMA-IR in GDM patients; Logistic regression method was used to analyze the influencing factors of GDM.Results:The levels of TG [ (2.94±0.99) mmol/L vs (2.09±0.70) mmol/L], FBG [ (5.87±1.94) mmol/L vs (4.90±1.67) mmol/L], TC [ (5.72±1.92) mmol/L vs (5.03±1.68) mmol/L], FINS [ (11.45±3.87) mIU/L vs (6.92±2.34) mIU/L], HOMA-IR [ (3.05±0.78) vs (1.51±0.40) ] and levels serum caspase-1 [ (86.27±28.78) pg/mL vs (40.98±13.54) pg/mL] and IL-18 [ (44.26±14.56) pg/L vs (30.45±10.12) pg/L] in the GDM group were higher than those in the normal group (t=7.080, 3.827, 2.731, 10.116, 17.743, 14.381, 7.866, P<0.05) ; the levels of serum caspase-1 and IL-18 in GDM patients were positively correlated with HOMA-IR ( r=0.518, 0.555, P<0.05) ; FBG, TG, FINS, HOMA-IR, caspase-1, IL-18 were risk factors affecting the occurrence of GDM (95% CI=1.578-3.826, 1.454-3.311, 1.477-3.405, 1.678-4.265, 1.406-3.141, 1.511-3.551, P<0.05) . Conclusions:The levels of serum caspase-1 and IL-18 in patients with GDM are relatively high, which are significantly related to IR. Caspase-1 and IL-18 may be potential targets for the treatment of GDM.

Pulmonary fibrosis(PF)is an irreversible lung disease that is characterized by excessive scar tissue with a poor median survival rate of 2-3 years.The inhibition of transforming growth factor-β receptor type-Ⅰ(TGF-β RI)by an appropriate drug may provide a promising strategy for the treatment of this disease.Polygonum cuspidatum(PC)is a well-known traditional Chinese herbal medicine which has an anti-PF effect.Accordingly,a combination of high resolution mass spectrometry with an in silico strategy was developed as a new method to search for potential chemical ingredients of PC that target the TGF-β RI.Based on this strategy,a total of 24 ingredients were identified.Then,absorption,distribution,meta-bolism,and excretion(ADME)-related properties were subsequently predicted to exclude compounds with potentially undesirable pharmacokinetics behaviour.Molecular docking studies on TGF-β RI were adopted to discover new PF inhibitors.Eventually,a compound that exists in PC known as resveratrol was proven to have excellent biological activity on TGF-β RI,with an ICso of 2.211 μM in vitro.Furthermore,the complex formed through molecular docking was tested via molecular dynamics simulations,which revealed that resveratrol had strong interactions with residues of TGF-β RI.This study revealed that resveratrol has significant potential as a treatment for PF due to its ability to target TGF-β RI.In addition,this research demonstrated the exploration of natural products with excellent biological activities toward specific targets via high resolution mass spectrometry in combination with in silico technology is a promising strategy for the discovery of novel drugs.

OBJECTIVE: To detect variant of TRNT1 gene in a child featuring sideroblastic anemia with B-cell immunodeficiency, periodic fever and developmental delay (SIFD). METHODS: The proband and his parents were analyzed through trio-whole exome sequencing. Sanger sequencing and bioinformatic analysis were carried out to verify the candidate variant sites associated with the clinical phenotype. RESULTS: Genetic testing showed that the proband has carried compound heterozygous variants of the TRNT1 gene, namely c.88A>G(p.Met30Val) and c.363G>T(p.Glu121Asp). Sanger sequencing confirmed that the variants were respectively inherited from his father and mother. The variants were unreported previously. By bioinformatic analysis, both variants were predicted to affect the stability of binding of the TRNT1 protein with tRNA. Based on the American College of Medical Genetics and Genomics standards and guidelines, c.88A>G and c.363G>T variants of TRNT1 gene were predicted to be uncertain significance (PM2+PP3+PP4) and likely pathogenic (PM1+PM2+PP3+PP4), respectively. CONCLUSION The c.88A>G (p.Met30Val) and c.363G>T(p.Glu121Asp) compound heterozygous variants of the TRNT1 gene probably underlay the disease in this patient. Above finding has enriched the spectrum of TRNT1 gene variants.

Inflammatory response is an important mechanism of secondary nerve injury in ischemic stroke, which is still a research hotspot in the field of neuroscience at present. Astrocytes are characterized by extensive distribution in brain, strong hypoxia tolerance, and the ability to interact with almost all cells in neurovascular unit, thus becoming potential therapeutic targets for alleviating ischemic injury. After ischemic stroke, astrocytes quickly become reactive astrocytes, releasing a large number of inflammatory cytokines, promoting the activation and invasion of other inflammatory cells, triggering a cascade of inflammatory responses, and aggravating ischemic injury. A variety of basic studies have shown that inhibiting the astrocytes activation and astrocytosis can significantly reduce neuroinflammatory response and infarct volume, and significantly improve the neurological function recovery in a model of middle cerebral artery occlusion. In this paper, the research progress of inflammatory response of astrocytes after ischemic stroke was reviewed from the aspects of astrocyte activation and polarization, release of inflammatory cytokines, interaction of inflammatory cells and corresponding targeted therapy strategies.
