Multiple myeloma(MM)remains an incurable disease,with most patients experiencing multiple relapses before ultimately progressing to refractory stage.Extramedullary infiltration is a common manifestation of relapse.However,distinguishing synchronous multifocal extramedullary infiltration from secondary malignancies poses significant diagnostic challenges.This study presents a case of relapsed refractory MM with multifocal extramedullary infiltration,diagnosed as coexistence of multiple myeloma extramedullary infiltration and pulmonary adenocarcinoma through multidisciplinary team(MDT)collaboration.Such coexistence is exceedingly rare in clinical practice and introduces substantial complexity in diagnosis and treatment planning.Through a comprehensive case report and literature review,this paper explores the diagnostic and therapeutic approaches to managing multifocal extramedullary infiltration coexisting with secondary malignancies in MM,highlighting the pivotal role of MDT in achieving precise diagnosis and optimizing patient outcomes.

Objective To develop an evidence-based practice program for ICU eye care and evaluate its application effect using Stetler model of research utilization.Methods The systematic search was carried out in domestic and foreign guid elines,systematic reviews,evidence summaries,expert consensuses on eye care for ICU patients.The quality of the included literature was evaluated and the evidence was summarized.The evidence based on expert advice,clinical context and stakeholder opinions was screened.According to Stetler model of research utilization,the evidence translation/application was formulated from 3 aspects,including method,level and type of evidence application,and the evidence translation was implemented using a stepwise trial design.Five ICUs in a tertiary hospital in Zhejiang Province were selected,and the order of enrollment of each ICU was determined by computer-generated random numbers from April to september,2022.In the first month,all ICUs were in pre-evidence-based practice period,and in the second month,an ICU was trained and entered the evidence-based practice period.Until the 6th month,all ICUs entered the evidence-based practice period.Then the rate of ocular symptoms and implementation rate of eye care measures were compared before and after EBP.Results A total of 1 540 patients were included.With regard to the implementation rate of eye care measures,the rate of lubricant use and suspected ocular infection management in patients at high risk for ocular complications in evidence-based practice period was significantly higher compared with pre-evidence-based practice period(P＜0.001),and no statistically significant difference was found in the rate of eyelid closure.The incidence of conjunctival exposure,subconjunctival hemorrhage,conjunctival congestion,and ocular discharge in non-neurology critical care patients decreased compared with pre-evidence-based practice period(P＜0.05),and the incidence of conjunctival edema and conjunctival congestion in NICU patients decreased compared with pre-evidence-based practice period as the intervention continued(P＜0.001).Conclusion Evidence-based practice in eye care for ICU patients using Stetler model of research utilization can standardize the practice of eye care for ICU patients and improve the quality of care.

Objective:To investigate the effects on perceived quality of a management assessment system for orthopedic surgery in elderly patients.Methods:Based on the concept of lean management and process nodes in systems, an information management system was established to evaluate the perceived quality of surgical service for elderly orthopedic patients.Four hundred and two elderly orthopedic patients receiving orthopedic surgery after the implementation of the management system were included in the observation group, while 402 elderly patients undergoing orthopedic surgery before the implementation of management system formed the control group.Results:The incidence of hypothermia in patients admitted to the resuscitation room after surgery was lower in the observation group than in the control group(1.7% vs.4.5%, χ2=5.136、 P=0.023). The incidence of shivering during resuscitation was lower and the satisfaction rate of surgical services was higher in the observation group than in the control group(0.7% vs.3.2%) χ2=5.279、 P=0.022, 96.55(95.58, 97.28)分, vs.87.9(83.2, 89.95)分, Z=-4.16, P=0.00). Conclusions:A perceived quality assessment system composed of lean management and information technology for surgical services can reduce complications and improve satisfaction for patients receiving surgery.

Objective To explore the effect of dexmedetomidine combined with sufentanil on postoperative analgesia , early postoperative cognitive function and serum inflammatory factors in patients with laparoscopic gastrectomy of gastric cancer.Methods 80 cases of laparoscopic resection of gastric cancer were randomly assigned to treatment group and control group.The control group were treated by sufentanil 1.6μg/kg.The treatment group were given sufentanil 1.6μg/kg combined with dexmedetomidine 2 μg/kg.The analgesic effect, early cognitive function and serum levels of inflammatory factors were tested and compared after surgery.Results Compared with the control group, the VAS score in 4 h,8 h,24 h and 48 h after surgery were lower in the treatment group (P<0.05), the POCD(P<0.05), the IL-6,IL-10 and TNF-αlevel were lower in the treatment group(P<0.05). Conclusion Dexmedetomidine combined with sufentanil showes better postoperative analgesic effect and fast recovery of cognitive function, regulate the levels of serum inflammatory cytokines after laparoscopic resection of gastric cancer .
