Objective To compare and analyze the effects of bipolar hemihip replacement(BHA)and total hip replacement(THR)in the treatment of femoral neck fracture(FNF).Methods The clinical data of 90 patients with FNF in the Luoyang Hospital,Dongzhimen Hospital,Beijing University of Chinese Medicine,from June 2019 to April 2023 were retrospectively collected.The patients were divided into two groups according to the difference in surgical treatment plan.The BHA group(45 cases)received BHA treatment,and the THR group(45 cases)received THR treatment.The perioperative indicators,preoperative and postoperative inflammatory factor levels,postoperative hip joint mobility at six months,preoperative and postoperative quality of life [European Quality of Life Scale(EQ-5D score)]were compared between the two groups.Results The operation time(108.76±15.33)min,ambulation time(40.37±10.24)h,and hospitalization time(19.02±5.11)d in the THR group were longer than those in the BHA group [(53.49±10.12)min,(25.92±7.15)h,(15.16±4.87)d](t=20.184,8.630,3.668,respectively,all P<0.05).The intraoperative blood loss(318.69±35.14)mL and postoperative drainage volume(129.74±21.03)mL were both higher than those in the BHA group [(224.07±29.35)mL,(90.35±17.48)mL](t=13.863,9.663,respectively,all P<0.001).There was no significant difference in the incidence of complications between the groups(P>0.05).Three days after surgery,the serum levels of interleukin-1,interleukin-6,and C-reactive protein in the BHA group were(17.35±3.06)pg/L,(24.82±4.31)pg/L,and(26.17±4.59)pg/L,respectively,which were lower than those in the THR group(20.16±3.48)pg/L,(27.04±5.06)pg/L,and(28.90±5.12)pg/L(t=4.068,2.241,2.663,respectively,all P<0.05).There was no significant difference in the range of motion of internal rotation,flexion,external rotation,abduction,and adduction of the hip joint and EQ-5D scores between the two groups at six months after surgery(all P>0.05).Conclusions Compared with THR,BHA can reduce perioperative blood loss in FNF patients,reduce postoperative inflammatory factor expression level,shorten operation and ambulation time,and promote recovery.
目的 探讨影响急性脑梗死患者接受重组组织型纤溶酶原激活剂(rt-PA)静脉溶栓治疗决策延迟的因素,并提出减少溶栓决策时间的建议。方法 采用回顾性分析方法,对泉州市第一医院2023年通过急诊收治的120例急性脑梗死患者及其家属的资料进行分析。根据溶栓决策时间,以5 min为界限,将患者分为非延迟组(62例)和延迟组(58例),并对两组资料进行比较分析。采用SPSS 23.0统计软件分析数据,运用t检验(针对连续变量)和χ 2 检验(针对分类变量)比较组间的差异。此外,通过Logistic回归分析,确定影响急性脑梗死患者静脉溶栓治疗决策的危险因素。结果 对比两组患者数据后发现,籍贯地区、冠心病史、外院转入、发病到入院时间以及决策家属数量比较差异具有统计学意义(P<0.05)。多因素Logistic回归分析进一步揭示,非泉州籍贯地区[OR(95%CI):9.29(2.21~38.97),P=0.002]、决策家属人数≥2人[OR(95%CI):18.73(5.96~58.80),P<0.001]、从外院转入[OR(95%CI):10.26(2.09~50.42),P=0.004]以及发病到入院时间3.0~4.5 h[OR(95%CI):4.09(1.45~11.48),P=0.008]是导致治疗决策延迟的独立危险因素。结论 患者非泉州籍贯地区、外院转入、溶栓决策家属人员≥2个、发病到入院时间3~4.5 h是溶栓决策延误的影响因素,提出优化卒中急诊抢救流程以及通过卒中宣教以缩短溶栓决策时间的建议。
Objective To investigate the factors influencing delays in decision-making for intravenous thrombolysis with recombinant tissue plasminogen activator(rt-PA)in patients with acute cerebral infarction and to propose recommendations for reducing thrombolysis decision-making time.Methods A retrospective analysis was conducted on data from 120 patients with acute cerebral infarction admitted to the emergency department at Quanzhou First Hospital in 2023,including information from their families.Patients were divided into non-delay group (62 cases) and delay group (58 cases) based on a 5-minute threshold for thrombolysis decision-making time.Comparative analysis between the two groups was performed using SPSS 23.0 statistical software,with t-tests for continuous variables and χ 2 tests for categorical variables.Logistic regression analysis was employed to identify risk factors affecting decision-making for intravenous thrombolysis in these patients.Results Statistical analysis revealed significant differences between the two groups in terms of native region,history of coronary heart disease,transfer from other hospitals,time from onset to hospital admission,and number of family members involved in decision-making(P<0.05).Multivariate Logistic regression identified independent risk factors for delayed treatment decisions:non-Quanzhou native region (OR[95%CI]:9.29[2.21-38.97],P=0.002),having two or more decision-making family members (OR[95%CI]:18.73[5.96-58.80],P<0.001),transfer from other hospitals (OR[95%CI]:10.26[2.09-50.42],P=0.004),and a time from onset to hospital admission of 3-4.5 hours (OR[95%CI]:4.09[1.45-11.48],P=0.008).Conclusions Factors such as non-Quanzhou native region,transfer from other hospitals,having two or more family members involved in decision-making,and a time from onset to hospital admission of 3-4.5 hours are associated with delays in thrombolysis decision-making.Optimizing the emergency rescue process for stroke and shortening the thrombolytic decision-making time through stroke education are suggested.
目的 探讨神经元型一氧化氮合酶(nNOS)在抑制剂N-硝基-左旋精氨酸甲酯(L-NAME)抑制作用下与新生鼠胃肠道疾病的相关性研究,以进一步研究婴儿肥厚性幽门狭窄(IHPS)等疾病的致病机制。方法 对40只成熟雌性wistar大鼠随机均分4组,怀孕后予怀孕母鼠灌胃,对照组给予生理盐水,低剂量组、中剂量组、高剂量组分别给予L-NAME 60、300、600 mg/(kg·d)L-NAME。新生鼠皮下注射方式,予对照组皮下注射生理盐水,在低剂量组、中剂量组、高剂量组皮下注射L-NAME 25、125、250 mg/(kg·d)L-NAME。统计分析新生鼠幽门中的nNOS表达量、体质量增长情况、胃潴留情况、幽门肌层厚度。结果 (1)低剂量组、中剂量组、高剂量组新生鼠幽门肌层厚度在出生后第1、7、14日龄高于对照组,但组间比较差异无统计学意义(P>0.05)。(2)与对照组相比,低剂量组、中剂量组、高剂量组的新生鼠出生后第1周体质量增加量更少,胃潴留更明显(P>0.05);在出生后的第2周各组体质量增加量差异无统计学意义(P>0.05)。(3)新生鼠出生后第14天,中剂量组的胃体积大于低剂量组,但低剂量组和对照组之间、中剂量组和高剂量组之间比较差异无统计学意义(P>0.05)。(4)新生鼠生后第1天,幽门中nNOS的表达被L-NAME以剂量依赖的方式被抑制,随着新生鼠日龄的增长,这种效应逐渐消失。(5)在不同剂量L-NAME的作用下,新生鼠幽门中nNOS表达量、趋势在不同时间点不同。结论 (1)nNOS可以导致新生鼠胃潴留、幽门梗阻,与IHPS相关症状之间存在相关性,但可能不是IHPS病因的唯一分子机制。(2)在新生鼠胃、幽门组织中,nNOS的表达量可以通过负反馈调节机制调节。(3)nNOS表达量上调可能有助于幽门舒张,但可能无法完全逆转IHPS中幽门的进一步肥厚和阻塞。
Objective To explore the effect of nNOS on the early postnatal pylorus of neonatal rats under the inhibition of the inhibitor N-nitro-L-arginine methyl ester hydrochloride(L-NAME),in order to further investigate the pathogenic mechanism of infantile hypertrophic pyloric stenosis(IHPS).Methods Pregnant female mice were grouped randomly and administered by gavage,with the control group receiving physiological saline,the low-dose,medium-dose and high-dose groups receiving different doses of L-NAME.For the neonatal rats,the control group was subcutaneously injected with physiological saline,while the low-dose group,medium-dose group,and high-dose group were subcutaneously injected with different doses of L-NAME.The expression of nNOS in the pylorus,weight gain,gastric retention,and pyloric muscle thickness of newborn rats were statistically analyzed.Results (1) The thickness of the pyloric muscle layer in the low-dose group,medium-dose group,and high-dose group of newborn rats was higher than that in the control group on the 1st,7th,and 14th day after birth,but there was no significant difference.(2)Compared with the control group,the neonatal rats in the low-dose group,the middle-dose group and the high-dose group gained less weight in the first week after birth,and the gastric retention was more significant.There was no significant difference in weight gain among the groups in the second week after birth.(3)On the 14th day after birth,the gastric volume of the medium-dose group was larger than that of the low-dose group,but there was no statistical difference between the low-dose group and the control group,or between the medium-dose group and the high-dose group.(4)On the first day after birth,the expression of nNOS in the pylorus of neonatal rats was significantly inhibited by L-NAME with dose-dependence,and this effect gradually disappeared with increasing age of neonatal rats.(5) Under the action of different doses of L-NAME,the expression level and trend of nNOS in the pylorus of neonatal mice vary at different time points.Conclusions (1) nNOS can cause gastric retention and pyloric obstruction in newborn rats,which is related to IHPS related symptoms,but may not be the only molecular mechanism of IHPS etiology.(2) The expression level of nNOS in the pyloric tissue of newborn mice can be regulated through a negative feedback regulatory mechanism.(3) Upregulation of nNOS expression may contribute to pyloric dilation,but may not completely reverse thickening and obstruction of the pylorus in IHPS.

Objective To investigate the inhibitory effect of polyphyllin I(PPI)on chronic myeloid leukemia cells(K562)and its possible mechanism.Methods K562 cell line was cultured in suitable environment,and the optimal concentration of the drug was screened by CCK-8 method.The optimal concentration of the drug cultured for 24 hours was used as the intervention concentration of the follow-up experiment.Cells were divided into the following groups:(1)blank group,(2)saponins group,(3)inhibitor group and(4)saponins + inhibitor group.The cell proliferation rate was detected by CCK-8 method.The cell morphology was observed by AO/EB staining.The apoptosis rate was detected by flow cytometry.The contents of reactive oxygen species(ROS),glutathione(GSH)and ferrous(Fe2+)in different groups were detected,and the expression of mRNA and protein in different groups were detected by qRT- PCR and Western blot respectively.Results PPI significantly inhibited the growth of K562 cells in a dose-and time-dependent manner.Compared with the blank group,PPI significantly inhibited the proliferation of K562 cells and increased the apoptosis rate of K562 cells,while the use of ferroptosis inhibitor(Ferrostian-1)reversed the promoting effect of PPI on apoptosis of K562 cells.Compared with the blank group,the contents of reactive oxygen species(ROS)and ferrous iron(Fe2+)increased and the content of glutathione(GSH)decreased in the saponins group.The use of Ferrostian-1 could down-regulate the contents of ROS and Fe2+ and increase the content of GSH in the cells treated with the drug.Compared with the blank group,the expression of p53 mRNA and protein in the saponins group increased,while the expression of SLC7A11,GPX4 mRNA and protein decreased.The expression of p53 mRNA and protein in the saponins + inhibitor group was lower than that in the saponins group,while the expression levels of SLC7A11,GPX4 mRNA and protein increased.Conclusions PPI can effectively inhibit the proliferation of K562 cells and promote ferroptosis in K562 cells.The molecular mechanism can be related to the regulation of p53 signal pathway.
