Objective To explore the value of the albumin-to-alkaline phosphatase ratio(AAPR)with modified Glasgow prognostic score(mGPS)in assessing the response to and prognosis of intravesical Bacillus Calmette-Guérin(BCG)therapy in patients with non-muscle invasive bladder cancer(NMIBC).Methods A total of 153 high-risk NMIBC patients treated with intravesical BCG in our hospital during Jan.2018 and Oct.2021 were enrolled.Patients were divided into response and non-response groups based on the treatment efficacy,and into good and poor prognosis groups based on the clinical outcomes.AAPR and mGPS were calculated.The relationship between AAPR,mGPS and BCG treatment non-response was analyzed with multivariate logistic regression.Clinical data and scores were compared between prognosis groups.The associations between AAPR,mGPS,and poor prognosis after BCG treatment were assessed with a Cox proportional hazards model.Patients were stratified into high-and low-A APR groups,and into mGPS 0,1,and 2 groups.Kaplan-Meier survival curves were plotted for progression-free survival(PFS)across different AAPR and mGPS strata.The diagnostic performance of AAPR combined with mGPS in predicting treatment non-response and poor prognosis was evaluated using receiver operating characteristic(ROC)curves.Results Among the 153 patients,the response rate to BCG treatment was 71.90％(110/153),the 3-year poor prognosis rate was 45.75％(70/153),and the 3-year PFS rate was 54.25％(83/153).Increased AAPR was identified as an independent protective factor for both treatment response and good prognosis,while higher mGPS was an independent risk factor(P＜0.05).The 3-year PFS rate was significantly higher in the high-AAPR group than in the low-A APR group(P＜0.001).Among the mGPS groups,the 3-year PFS rate was lowest in the mGPS 2 group,followed by mGPS 1 and mGPS 0 groups(P＜0.001).The area under the ROC curve(AUC)for AAPR with mGPS in predicting BCG treatment non-response and poor prognosis was 0.864 and 0.901,respectively,significantly higher than using AAPR(0.774,0.781)or mGPS alone(0.798,0.809)(P＜0.05).Conclusion Lower AAPR and higher mGPS are associated with non-response and poor prognosis in NMIBC patients undergoing intravesical BCG therapy.The combination of AAPR and mGPS has high predictive value.

Objective To explore the active monitoring strategies for hypoglycemia in hospitalized dia-betic patients,as well as their clinical symptom characteristics and influencing factors.Methods A retrospec-tive search was conducted on all inpatients in a tertiary hospital in 2023.The hospital's electronic medical re-cord system was manually retrieved through the inpatient numbers of the patients.Adult inpatients with dia-betes who experienced hypoglycemia were included as the research subjects,and the general conditions and possible hypoglycemia-related risk factors were collected.Embed the hypoglycemic electronic trigger program in China Hospital Pharmacovigilance System(CHPS),reviewed the original medical records of patients with positive trigger triggering,and calculated the positive predictive value(PPV).Searched for the number of hy-poglycemic adverse reaction cases voluntarily reported by this hospital during the same period from National Adverse Reaction Monitoring System and compared with the actual number of hypoglycemic cases discovered.Patients with suspected drug-induced hypoglycemia were divided into the symptomatic group and the asymp-tomatic group based on whether they presented hypoglycemia-related symptoms.Multivariate logistic regres-sion analysis was applied to analyze the influencing factors.Results A total of 1 001 adult hospitalized diabet-ic patients with hypoglycemia were included in the study.Among them,725 cases were suspected of drug-in-duced hypoglycemia,and 495 cases were suspected of hypoglycemia caused by drug interactions.After manual review,131 cases of drug-induced hypoglycemia patients had clinical symptoms,and hypoglycemic adverse re-action events should be reported,PPV of this trigger for symptomatic hypoglycemia was 18.1%(131/725).However,the number of hypoglycemic adverse reactions spontaneously reported through National Adverse Reaction Monitoring System by this hospital during the same period was 4 cases,and the reporting rate was only 3.1%(4/131).Multivariate logistic regression analysis showed that aging and grade 2 hypoglycemia were risk factors for the occurrence of related symptoms in patients with suspected drug-induced hypoglycemia(P<0.05),while surgery,type 2 glucosuria,unclassified diabetes,and the use of insulin secretagogues were protective factors(P<0.05).Conclusion Drug-induced hypoglycemia dominates among hospitalized diabetic patients,and age,hypoglycemia grade,inpatient department using insulin secretagogues,diabetes diagnosis and classification are closely related to the occurrence of clinical hypoglycemia-related symptoms.Active monito-ring through CHPS can effectively increase the detection rate and reporting rate of hypoglycemic adverse e-vents in hospitalized diabetic patients.

Kidney transplantation is widely recognized as the optimal treatment for children with end-stage renal disease(ESRD),offering significant improvements in growth,development,and long-term quality of life compared with prolonged dialysis.However,kidney transplantation in low-age(＜5 years old)and low-weight(＜15 kg)children presents significant clinical challenges due to their delicate vas-cular structures,limited surgical space,and complex perioperative management.This report presents two cases of kidney transplantation in low-age,low-weight children performed at Peking University People's Hospital.Case 1:a 2-year-3-month-old boy(8.8 kg),presenting a preoperative serum creatinine of 248μmol/L post-dialysis and the estimated glomerular filtration rates(eGFR)of 35.17 mL/(min·1.73 m2).Case 2:a 3-year-8-month-old girl(11.25 kg),presenting a preoperative creatinine of 281 μmol/L post-dialysis and the eGFR of 22.63 mL/(min·1.73 m2).Both recipients underwent transplantation via the extraperitoneal approach,with end-to-side anastomosis of the donor renal artery and vein to the recipient's common iliac artery and vein,respectively.The ureters were anastomosed to the bladder using the tunnel technique,and double-J stents were placed intraoperatively.The surgeries were uneventful,and both pa-tients exhibited rapid recovery of renal function.Postoperatively,serum creatinine levels decreased to 26μmol/L(Case 1)and 39 μmol/L(Case 2)by the third day,with the eGFR reaching 245.23 mL/(min·1.73 m2)and 164.12 mL/(min·1.73 m2),respectively.No complications,such as vascular thrombosis,ureteral stenosis,or abdominal compartment syndrome were observed during follow-up.A comprehensive literature review was conducted to contextualize these cases within global advancements in pediatric renal transplantation.Current evidence highlights the growing adoption of kidney transplantation for low-age,low-weight children,though debates persist regarding optimal surgical strategies(specifical-ly,the intraperitoneal versus extraperitoneal approaches).This case report underscores the feasibility of the extraperitoneal approach in overcoming anatomical limitations of low-weight pediatric recipients,with distinct advantages including reduced gastrointestinal complications and enhanced accessibility for post-operative ultrasound monitoring.Furthermore,mean arterial pressure(MAP)and central venous pressure(C VP)were systematically monitored intraoperatively to ensure optimal renal blood perfusion and graft viability.Our single-center experience provides valuable insights into surgical strategy selection and peri-operative management for this high-risk population.Nevertheless,larger multicenter studies are warranted to validate long-term outcomes and refine standardized protocols.

Gallstones are the primary benign disease diagnosed and treated in biliary surgery.With the development of medical technology and the increasing awareness of health among the population,the detection rate of gallstones has been increasing annually,with the majority being asymptomatic or mild cases.Currently,the clinical treatment of gallstones mainly includes observation,conservative,or surgical treatment(laparoscopic cholecystectomy).However,there remains some controversy regarding the clinical management of these patients.For asymptomatic or mild gallstones,the main point of contention in both academic and clinical settings is how to determine the indications for cholecystectomy.This article reviews relevant literature from both domestic and international sources,addressing the controversies surrounding the clinical management of gallstones and the determination of indications for cholecystectomy,and elaborates on these issues from multiple perspectives.

Cerebral proliferative angiopathy(CPA)was initially regarded as a variant of arteriovenous malformation.However,its distinct histological,angiographic,and pathophysiological features have led to its reclassification as an independent entity.CPA is an exceptionally rare form of cerebral vascular malformation,its pathogenesis is primarily linked to diffuse vascular proliferation secondary to chronic hypoperfusion.Clinically,CPA presents with a heterogeneous spectrum of manifestations,most commonly severe headaches and epileptic seizures.Neuroimaging(MR)typically reveals a complex interplay of aberrant vessels within the brain parenchyma,which may complicate the clinical management and lead to a higher rate of poor prognosis.This article reviewed current knowledge on the pathogenesis,epidemiology,clinical features,diagnostic approaches,and treatment options for CPA,with the aim of enhancing understanding of its underlying mechanisms and guiding future therapeutic strategy optimizations.

Objective To investigate the effects of Remimazolam combined with Esketamine on cellular immunity,cognitive function,and sleep quality in elderly patients with lung cancer during surgery.Methods A total of 106 elderly lung cancer patients who underwent elective thoracoscopic lobectomy from September 2023 to March 2025 were selected and divided into the control group(n=53)and the research group(n=53)according to random number table method.The control group received Midazolam combined with Esketamine for general anesthesia,while the research group received Remimazolam combined with Esketamine for general anesthesia.The intraoperative and postoperative conditions,hemodynamic parameters[heart rate(HR),mean arterial pressure(MAP)]before anesthesia induction(T0),at tracheal intubation(T1),at 1 min before one-lung ventilation(OLV)(T2),at skin incision(T3),at 1 h after OLV(T4),and immediately after extubation(T5),as well as pain and inflammatory factors[5-hydroxytryptamine(5-HT),prostaglandin E2(PGE2),high-sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α)],cellular immunity[peripheral blood natural killer(NK)cells,CD3+,CD4+,CD4+/CD8+],the levels of serum interleukin(IL)-2,interferon-γ(IFN-γ),cognitive function[Mini-Mental State Examination(MMSE)],sleep quality[Pittsburgh Sleep Quality Index(PSQI)],and recovery quality[Postoperative Quality of Recovery-15(QoR-15)score]were compared between the two groups of patients.The adverse reactions and complications were also compared between the two groups.Results There was no significant difference in duration of surgery,duration of anesthesia,intraoperative blood loss,and time to spontaneous breathing recovery of patients between the two groups(P>0.05).The total dosage of Sufentanil in the research group was less than that in the control group,and time to postoperative eye opening,duration of recovery room stay and length of postoperative hospitalization were shorter than those in the control group(P<0.05).At T0 and T5,there was no significant difference in HR and MAP between the two groups(P>0.05),and at T1-T4,HR and MAP in the research group were higher than those in the control group(P<0.05).At the time of recovery,the levels of serum 5-HT,PGE2,hs-CRP,and TNF-α in the research group were lower than those in the control group(P<0.05),and at the time of recovery,the peripheral blood NK cells,CD3+,CD4+,and CD4+/CD8+ratio,serum IL-2 and IFN-γ levels in the research group were higher than those in the control group(P<0.05).At 1 d after surgery,the MMSE and QoR-15 scores of the research group were higher than those of the control group,while the PSQI score was lower than that of the control group(P<0.05).The incidence of adverse reactions and complications in the research group[5.66%(3/53)and 3.77%(2/53)],was lower than that of the control group[18.87%(10/53)and 15.09%(8/53)](P<0.05).Conclusion The combination of Remimazolam and Esketamine in elderly patients undergoing thoracoscopic lobectomy can better maintain intraoperative hemodynamics,stabilize cellular immune function,reduce serum pain and inflammatory factor levels,improve postoperative cognitive function and sleep quality,reduce adverse reactions and complications,and promote postoperative recovery.

BACKGROUND:Unilateral knee osteoarthritis patients experience abnormal alterations in lower extremity gait biomechanics,yet few studies have analyzed changes in gait dynamics and muscle activation in knee osteoarthritis patients from the perspective of gait asymmetry.OBJECTIVE:To explore the effects of unilateral knee osteoarthritis on gait dynamics and muscle activation asymmetry in elderly women.METHODS:Thirty female patients with unilateral knee osteoarthritis attending Beijing Jishuitan Hospital Guizhou Hospital from October 2023 to March 2024 were selected as the knee osteoarthritis group,and 30 healthy elderly females without musculoskeletal disorders from the neighboring community were recruited as the control group.The kinetic and muscle activation levels of the subjects in both groups during walking were synchronously collected by a P-6000 force platform and a Free EMG300 surface EMG device.Kinetic parameters included the first and second peak forces of vertical ground reaction force.Muscle activation indexes included normalized root mean square values of rectus femoris,long head of biceps femoris,and lateral gastrocnemius muscle during the braking and pushing phases.Asymmetry index of the kinetic and muscle activation indexes were calculated separately in patients with K-L grade Ⅱ and Ⅲ knee osteoarthritis and controls and compared between groups by independent samples t-test and one-way analysis of variance.RESULTS AND CONCLUSION:(1)The difference between the second peak of vertical ground reaction force of both limbs in the knee osteoarthritis group was statistically significant(P＜0.05),as well as the difference between the standardized root mean square of rectus femoris in the braking phase and gastrocnemius and biceps femoris in the pushing phase(P＜0.05).(2)In terms of asymmetry index,the difference between the asymmetry index values of the first peak of vertical ground reaction force between the two groups of subjects was not statistically significant(P＞0.05),while the difference between the second peak asymmetry index values was statistically significant(P＜0.05).The difference in asymmetry index values of standardized root mean square of rectus femoris muscle during the braking phase as well as gastrocnemius and biceps femoris muscles during the pushing phase was statistically significant between the two groups of subjects(P＜0.05).(3)The asymmetry index of the standardized root mean square values of the second peak of vertical ground reaction force,rectus femoris in the braking phase,gastrocnemius in the pushing phase,and biceps femoris in the osteoarthritis group of the knee with K-L classification grade Ⅱand Ⅲ were significantly higher than those of the control group(P＜0.05).The asymmetry indices of standardized root mean square values of the second peak of vertical ground reaction force,rectus femoris in the braking phase and biceps femoris in the pushing phase were higher in the osteoarthritis group of the knee with K-L classification Ⅲ than in the osteoarthritis group of the knee with classification Ⅱ(P＜0.05).(4)The asymmetry indices of the second peak of vertical ground reaction,the rectus femoris muscle in the braking phase,and the muscle activation of the biceps femoris and gastrocnemius muscles in the pushing phase can be used as an important index for identifying gait asymmetry in the knee osteoarthritis,which is helpful in providing a theoretical basis for the development of rehabilitation treatment programs.It is also worth noting that extra attention should be paid to patients with higher severity of knee osteoarthritis in the clinical monitoring of gait asymmetry.

OBJECTIVE To optimize the optimum processing technology of vinegar-processed Artemisiae Argyi Folium(AAF),and analyze the difference of index components and analgesic activity before and after processing.METHODS The method for the determination of total flavonoids and total terpenes in AAF was established with eupatilin and Santamarine as control substances,re-spectively.The HPLC-VWD method was established for the simultaneous determination of 6-Methoxytricin,Santamarine,eupatilin and Artemisolide in AAF.Box-Behnken design-response surface method was used to optimize the processing technology of vinegar-processed AAF,with the content of total flavonoids,total terpenes and four active ingredients as the index,and the amount of rice vin-egar,moistening time,processing temperature and processing time as the factors.The quantitative analysis was combined with hierar-chical cluster analysis(HCA),principal component analysis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)to evaluate the difference of index components before and after processing.The analgesic activity before and after processing was investigated using pain mice induced by formalin.RESULTS The optimum processing parameters of vinegar-processed AAF were 16%rice vinegar dosage,moistening time 50 min,processing temperature 160℃and processing time 12 min.There were significant differences in the content of index components before and after processing.The analgesic activity of vinegar-processed AAF was signifi-cantly better than that of AAF.CONCLUSION The optimized processing technology is stable and feasible,which can provide scien-tific basis for standardizing production of vinegar-processed AAF.
