Patients with alcoholic cirrhosis often experience varying degrees of malnutrition， and the patients with malnutrition are more susceptible to complications such as infections and ascites， which may lead to a poor prognosis. Therefore， it is particularly important to conduct nutritional risk screening for patients in clinical practice， and appropriate nutritional assessment tools should be used to evaluate the nutritional status of patients and develop individualized nutritional supplementation regimens， thereby promoting disease recovery and improving prognosis and quality of life. This article elaborates on the specific methods for nutritional screening， assessment， and management in patients with alcoholic cirrhosis and points out that systematic nutritional screening and assessment can help to identify the patients with malnutrition in the early stage and provide timely intervention. Individualized nutritional supplementation regimens should be adjusted based on the conditions of patients， so as to meet their nutritional needs， promote the recovery of liver function， improve overall health status， and enhance long-term quality of life.

Objective:To explore the role of serum cholinesterase (CHE) levels in the prognosis of patients with acute decompensated heart failure (ADHF).Methods:Total of 244 consecutive patients with ADHF who were admitted to the emergency department and were successfully discharged were prospectively enrolled from January 2018 to June 2020. Patients were divided into groups according to the first and third quartile of CHE level and the clinical data, laboratory tests and other nutritional indices were recorded after discharge, and then were followed up. The primary end points were the composites of cardiovascular death and hospitalization for worsening HF (composite end points). The secondary end points were all-cause mortality and cardiovascular death. Cox proportional risk analysis, time-dependent Cox regression model or stratified cox regression were used to identify the risk of primary and secondary endpoints. Clinical, biomarker and the compound models of clinical and biomarker were constructed. Kaplan-Meier method was used to plot the survival curves of different groups and compare their differences. Receiver Operating characteristics (ROC) curves were used to compare the area under the curve for CHE levels and other nutritional or prognostic indicators to identify composite end-point events.Results:During a follow-up period of 350(100,683) days, 158 patients reached the composite end points. In the multivariable Cox analysis, cholinesterase level was significantly associated with the composite end points after adjustment for major confounders. Cox proportional risk analysis or time-dependent Cox regression model showed that CHE level was significantly associated with the composite end points, all-cause mortality and cardiovascular mortality in both clinical, biomarker and composite models (all P< 0.05). A Kaplan–Meier analysis revealed that patients with low cholinesterase levels had significantly greater risk of reaching the composite end points than those with middle or high cholinesterase levels (78.1% vs 66.7% vs. 46.7%, P<0.001); Cholinesterase level showed the largest area under the receiver operating characteristic curve (AUROC) of 0.736 (95% CI, 0.664-0.888) for prediction of the composite end points among other nutritional indices. The AUROC of the Global Meta-Analysis Group Chronic Heart Failure (MAGGIC) Risk Score for prediction of the composite end points was increased from 0.704 to 0.762 ( P=0.038), when cholinesterase level was added. Conclusions:Cholinesterase may serve as a simple and effective prognostic marker for predicting adverse outcomes in ADHF patients.

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 summarize the isolation and drug resistance rate of Escherichia coliin The First Hospital of China Medical University over the past 10 years,in order to provide evidence for the efficacies of clinical anti-infection treatments.Methods The data was collected from Escherichia coli isolated from patients treated at The First Hospital of China Medical University between 2013 and 2022.VITEK 2 and VITEK MS were used for bacterial identification,VITEK2 and KB method were used for drug sensi-tivity testing,and WHONET 5.6 software was used for analysis.Results From 2013 to 2022,6 845 strains were isolated,including 80.5%from inpatients and 19.5%from emergency and outpatients.The specimens were most commonly found in the urine(57.8%),blood(15.0%),secretions(9.2%),and drainage fluid(8.1%).The isolation rate of extended-spectrumβ-lactamase(ESBL)producing Escherichia coli was 57.2%(54.3%to 61.5%).The drug resistance rate of Escherichia coli to carbapenems was low,at only 1.2%(0.2%to 2.6%).Conclusion Escherichia coli remains an important pathogen in clinical infections,with varying degrees of resist-ance to multiple antibiotics,and the resistance rate is increasing.Clinical physicians should pay sufficient attention to this issue.

Objective:To observe any effect of repetitive transcranial magnetic stimulation (rTMS) on sleep disorders among children with cerebral palsy (CP).Methods:A total of 102 children with CP and disordered sleep were randomly divided into an experimental group and a control group, each of 51. All were given routine rehabilitation and sleep health education, but the experimental group additionally received rTMS for two weeks. The polysomnography (PSG) results of the two groups were recorded and analyzed.Results:The PSG parameters had improved greatly in both groups after the treatment. The percentage of N2 sleep (depth of sleep during light sleep) in the severe cerebral palsy group and of N3 sleep (depth of sleep during deep sleep) in the moderate cerebral palsy group had increased significantly more than in the mild cerebral palsy group, on average. After the intervention the percentages of N2 and N3 in those with mixed cerebral palsy and of N3 in those with involuntary motor cerebral palsy had increased significantly more than in those with spastic cerebral palsy, on average.Conclusion:rTMS treatment can improve the sleep disorders of children with cerebral palsy, especially N2 sleep among children with moderate to severe cerebral palsy, N3 sleep in cases of mixed or dyskinetic CP.

Objective:To observe the effect of Nodal on the biological behavior of retinal vascular endothelial cells (RF/6A cells) in monkeys with high glucose.Methods:RF/6A cells were divided into normal group, mannitol group, high glucose group, high glucose combined with non-specific small interfering RNA treatment group (HG+NC group), high glucose combined with small interfering Nodal treatment group (HG+siNodal group). The transfection efficiency of siNodal was observed by real-time fluorescence quantitative PCR and western blot protein immunoblotting. The effect of Nodal on the proliferation of RF/6A cells was detected by thiazole blue colorimetry. The effect of Nodal on migration ability of RF/6A cells was detected by cell scratch assay. The effect of Nodal on the formation of RF/6A cell lumen was measured by Matrigel three-dimensional in vitro. The expression of extracellular signal phosphorylated regulated kinase 1/2 (pERK1/2) in RF/6A cells was detected by western blot protein immunoblotting. One-way analysis of variance was used to compare groups.Results:Compared with HG+NC group, Nodal protein ( F=33.469) and mRNA relative expression levels ( F=38.191) in HG+siNodal group were significantly decreased, cell proliferation was significantly decreased ( F=28.548), and cell migration ability was significantly decreased ( F=24.182). The number of cell lumen formation was significantly decreased ( F=52.643), and the differences were statistically significant ( P<0.05). Compared with HG+NC group, the relative expression of pERK1/2 protein in HG+siNodal group was significantly decreased, and the difference was statistically significant ( F=44.462, P<0.01). Conclusions:Silencing Nodal expression can inhibit proliferation, migration and tube formation of RF/6A cells induced by high glucose. It may act by inhibiting pERK1/2 expression.

Objective:To explore the expression relationship and significance of long chain non-coding RNA nuclear-enriched abundant transcript 1(LncRNA NEAT1)and miR-27a-3p in serum and cerebro-spinal fluid of patients with Alzheimer disease(AD).Methods:Sixty-six AD patients received by the department of neurology of our hospital from October 2019 to September 2021 were gathered,according to the clinical dementia rating scale score,they were grouped into mild group(≤ 1 point,n=41)and moderate-to-severe group(＞1 point,n=25).Another 66 cases of serum and cerebrospinal fluid sam-ples from outpatient physical examination personnel were regarded as the control group.The general infor-mation on all subjects was recorded and cognition was assessed;real-time quantitative PCR was performed to measure the expression levels of miR-27a-3p and NEAT1 in serum and cerebrospinal fluid;enzyme-linked immunosorbent assay was performed to measure the protein levels of β-amyloid precursor protein cleaving enzyme 1(BACE1),β-amyloid(Aβ)40 and Aβ42 in cerebrospinal fluid;Spearman's method was performed to analyze the correlation of serum miR-27a-3p and NEAT1 levels with mini-mental state examination(MMSE)and montreal cognitive assessment(MoCA)scores;Pearson method was per-formed to analyze the correlation between serum miR-27a-3p and NEAT1 levels and Aβ deposition standard uptake value ratio(SUVR)and cerebrospinal fluid miR-27a-3p,NEAT1,BACE1,Aβ42 and Aβ40 levels.Results:The MMSE score[21(17,25),9(7,11)vs.27(21,34)],MoCA score[17(12,21),10(7,13)vs.27(21,31)],serum miR-27a-3p level(0.55±0.13,0.46±0.06 vs.0.97± 0.22),cerebrospinal fluid miR-27a-3p(0.48±0.10,0.35±0.10 vs.1.03±0.31),Aβ42 levels[(303.55±36.77)ng/L,(231.45±34.14)ng/L vs.(499.99±53.63)ng/L]and Aβ42/Aβ40 ra-tio(0.030±0.008,0.022±0.007 vs.0.048±0.010)of AD patients in mild group and moderate-to-severe group were all lower than those in the control group,and the moderate-to-severe group were lower than the mild group(all P＜0.05);the serum NEAT1 level(2.31±0.64,3.13±0.76 vs.1.05± 0.20),SUVR(1.50±0.29,1.76±0.52 vs.0.74±0.15),and cerebrospinal fluid NEAT1(3.51± 1.24,4.30±1.65 vs.1.01±0.23)and B ACE 1 levels[(55.78±5.98)μg/L,(72.32±16.08)μg/L vs.(21.39±3.73)μg/L]were higher than those in the control group,and the moderate-to-se-vere group were higher than the mild group(all P＜0.05).Serum NEAT1 level in AD patients was posi-tively correlated with SUVR,cerebrospinal fluid NEAT1 and BACE1(r=0.350,0.606,0.341,P＜0.05),and negatively correlated with MMSE score and MoCA score(r=-0.473,-0.482,all P＜0.05);serum miR-27a-3p level was positively correlated with cerebrospinal fluid miR-27a-3p level,MMSE score and MoCA score(r=0.695,0.424,0.412,all P＜0.05),and negatively correlated with SUVR and cerebrospinal fluid BACE1 level(r=-0.521,-0.447,all P＜0.05).Conclusion:The expression trends of NEAT1 and miR-27a-3p in the serum and cerebrospinal fluid of AD patients are con-sistent,the level of NEAT1 is increased,and the level of miR-27a-3p is decreased.The levels of the two are negatively correlated,which is related to the degree of Aβ deposition in the brain of AD patients and is involved in the progression of AD.

Afferent baroreflex failure(ABF)is a rare disease.It refers to the clinical syndrome caused by the impairment of the afferent limb of the baroreflex or its central connections at the level of the medul-la.The recognized causes include trauma,surgery in related areas(radical neck tumor surgery,carotid endarterectomy),neck radiotherapy,brain stem stroke,tumor growth paraganglioma and hereditary diseases,among which the most common cause is extensive neck surgery or radiotherapy for neck cancer.The main manifestations are fluctuating hypertension,orthostatic hypotension,paroxysmal tachycardia and bradycardia.This case is a young man,whose main feature is blood pressure fluctuation,accom-panied by neurogenic orthostatic hypotension(nOH).After examination,the common causes of hyper-tension and nOH were ruled out.Combined with the previous neck radiotherapy and neck lymph node dissection,it was considered that the blood pressure regulation was abnormal due to the damage of carotid sinus baroreceptor after radiotherapy for nasopharyngeal carcinoma and neck lymph node dissection,which was called ABF.At the same time,the patient was complicated with chronic hyponatremia.Com-bined with clinical and laboratory examination,the final consideration was caused by syndrome of in-appropriate antidiuretic hormone(SIADH).Baroreceptors controlled the secretion of heart rate,blood pres-sure and antidiuretic hormone through the mandatory"inhibition"signal.We speculate that the carotid sinus baroreceptor was damaged after neck radiotherapy and surgery,which leads to abnormal blood pres-sure regulation and nOH,while the function of inhibiting ADH secretion was weakened,resulting in higher ADH than normal level and mild hyponatremia.The goal of treating ABF patients was to reduce the frequency and amplitude of sudden changes in blood pressure and heart rate,and to alleviate the on-set of symptomatic hypotension.At present,drug treatment is still controversial,and non-drug treatment may alleviate some patients'symptoms,but long-term effective treatment still needs further study.The incidence of ABF is not high,but it may lead to serious cardiovascular and cerebrovascular events,and the mechanism involved is extremely complicated,and there are few related studies.The reports of rele-vant medical records warn that patients undergoing neck radiotherapy or surgery should minimize the da-mage to the baroreceptor in the carotid sinus in order to reduce the adverse prognosis caused by complica-tions.

Objective:To explore the efficacy and safety of tislelizumab combined with zanubrutinib in the treatment of refractory diffuse large B-cell lymphoma (DLBCL).Methods:A prospective observational study was conducted. A total of 10 patients with refractory DLBCL admitted to Beijing Chaoyang District Third Ring Cancer Hospital, a specialist medical consortium of Cancer Hospital Chinese Academy of Medical Sciences from November 2020 to February 2023 were prospectively collected. All the 10 refractory DLBCL patients at least received first-line systemic therapy containing rituximab; and they were given tislelizumab 200 mg, intravenous infusion, on day 1 and zanubrutinib 160 mg, orally, twice a day, day 1-day 21, with 21 days as 1 cycle; 6 patients received second-line therapy and 4 patients received ≥ third-line therapy. Subsequent regimens were added with rituximab (375 mg/m 2, intravenous infusion on day 1). The primary endpoint will be reached 12 months after enrollment if there was no disease progression or other events that were scheduled to withdraw from the study. The therapeutic efficacy was summarized at the end of the follow-up in March 2023. Kaplan-Meier method was used to make survival analysis and the adverse reactions were summed up. Results:There were 6 males and 4 females, all at stage Ⅲ-Ⅳ; and age [ M ( Q1, Q3)] was 55 years (50 years, 69 years). All 10 patients completed 90 cycles of treatment with tislelizumab and zanubrutinib, with the cycle number of 8 cycles (2 cycles, 24 cycles). The follow-up time was 19 months (11 months, 28 months); 4 cases achieved complete remission, 3 cases achieved partial remission and 1 case had the stable disease. The progression-free survival was 8.5 months (1.3 months, 27.0 months); the median remission duration time and median overall survival time were not reached. Treatment-related adverse reactions included 2 cases of neutropenia, 1 case of anemia, and 1 case of elevated alanine aminotransferase and aspartate aminotransferase, all of which were grade 1-2. Conclusions:Tislelizumab combined with zanubrutinib has good clinical efficacy and safety in the treatment of refractory DLBCL.
