Objective: To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention. Methods: From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated. Results: Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group. Conclusion Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

Definitive treatment of lung cancer with radiotherapy is challenging, as respiratory motion and anatomical changes can increase the risk of severe off-target effects during radiotherapy. Online adaptive radiotherapy (ART) is an evolving approach that enables timely modification of a treatment plan during the interfraction of radiotherapy, in response to physiologic or anatomic variations, aiming to improve the dose distribution for precise targeting and delivery in lung cancer patients. The effectiveness of online ART depends on the seamless integration of multiple components: sufficient quality of linear accelerator-integrated imaging guidance, deformable image registration, automatic recontouring, and efficient quality assurance and workflow. This review summarizes the present status of online ART for lung cancer, including key technologies, as well as the challenges and areas of active research in this field.

Objective To explore the characteristics of military training injuries in high-altitude troops and determine the possible impact of daily diet on these training injuries in order to provide theoretical reference for scientific training and medical service support for high-altitude troops.Methods A cross-sectional scheme was adopted in this study.A self-designed Military Training Injury Questionnaire for Plateau Troops was used to survey the officers and soldiers from resident high-altitude troops in July 2024 for their training injuries,daily diet,and other situations.The obtained data were statistically analyzed.Results Among the 3 655 participants,the incidence of military training injuries was 17.87%.The subject with highest incidence was physical training(45.94%),the most common season was winter(31.39%).The most common sites of injury were waist(28.48%),knees(22.21%),and ankles(18.07%),and the most common types were sprains(28.48%),chronic fatigue injuries(18.38%)and strains(12.25%).The intake amounts of coarse grains and potatoes,bean products,aquatic products and nuts were relatively low in the daily diet of high-altitude troops.Multivariate logistic regression analysis found intake of fruit(OR=0.625,95%CI:0.508～0.768,P<0.001)and of nut(OR=0.759,95%CI:0.654～0.879,P<0.001)were correlated with the occurrence of training injury.Conclusion The occurrence pattern of military training injuries in high-altitude troops in this survey is basically consistent with that of previous reports,but the incidence rate is slightly decreased.Regular consumption of fruit and nut may be protective factors for the occurrence of training injuries.

Objective:To investigate the long-term prognosis of liver transplantation (LT) recipients who received grafts from donors aged ≥80 years and the associated risk factors.Methods:Clinical and follow-up data of LT recipients from January 2002 to June 2023 were retrospectively analyzed using the United Network for Organ Sharing (UNOS) database. Donors were categorized into three groups : non-elderly donors (NED, age < 60 years), elderly donors (ED, age 60-79 years), and very elderly donors (VED, age ≥80 years). Propensity score matching (PSM) was used to reduce baseline selection bias among the groups. Survival rates were calculated using the Kaplan-Meier method, and differences among the groups were compared using the Log-Rank test. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify independent risk factors for overall survival (OS) in the VED group. Recipients were further subdivided into three age groups (<50 years, 50-69 years, and ≥70 years) to compare survival outcomes among NED, ED, and VED groups.Results:A total of 115, 089 LT recipients were included, comprising 95, 973 (83.4%) in the NED group, 18, 520 (16.1 %) in the ED group, and 596 (0.5 %) in the VED group. After 3∶3∶1 PSM, each group included 1, 623 recipients for NED and ED, and 541 for VED, with no significant differences in baseline data. The 10-year OS rates for NED, ED, and VED groups were 61.8%, 55.9%, and 47.8%, respectively, and the 10-year graft survival (GS) rates were 61.3 %, 53.8%, and 45.9 %, respectively, with all comparisons showing statistical significance ( P< 0.001). In recipients aged <70 years, the VED group had significantly lower OS and GS rates (49.0% and 47.1 %, respectively ) compared to the NED (63.7 % and 61.8%) and ED (57.7% and 55.2 %) groups ( P< 0.001 ). For recipients aged ≥70 years, there were no significant differences in 10-year OS and GS among the NED (47.2% and 48.7 %), ED (47.0 % and 48.7 %), and VED (40.0 % and 39.2 %) groups ( P= 0.992 and P= 0.996, respectively). Cox regression analysis identified cold ischemia time ≥8 hours ( HR=1.447, 95% CI: 1.088-1.923, P=0.011), pre-transplant ICU dependence ( HR=1.803, 95% CI: 1.176–2.765, P=0.007), and hepatitis B/C virus infection ( HR =1.432, 95% CI: 1.057-1.941, P=0.020) as independent risk factors for OS in the VED group. Conclusions:Liver grafts from VED grafts significantly reduce long-term OS and GS in recipients, except in those aged ≥70 years where prognosis is comparable to recipients of NED and ED grafts.. For the VED group, factors such as cold ischemia time ≥8 hours, pre-transplant ICU dependence, and hepatitis B/C virus infection markedly influence the prognosis.

To analyze the clinical characteristics and follow-up data of Chinese patients with calcium-sensing receptor (CaSR) signaling pathway related hypercalcemia. A retrospective analysis was conducted on six children with hypercalcemia admitted to Department of Endocrinology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from July 2017 to November 2022. Summarized the clinical and pathogenic variants, as well as follow-up data. The results showed that 3 were female and 3 were male of the 6 cases, aged from 2 months to 8 years at the consultation. The clinical symptoms varied from asymptomatic hypercalcemia to vomiting, dehydration, and growth retardation,as well as epilepsy and intellectual disability. Except for 1 case, which showed a significant increase in blood calcium (4.63 mmol/L), the blood calcium of other cases ranged from 2.98 to 3.17 mmol/L. Among the 6 patients, 5 had elevated parathyroid hormone, and 1 was normal. Three cases showed a significant decrease in 24-hour urinary calcium to creatinine ratio. Whole exome sequencing revealed that one patient had compound heterozygous variants and four had a heterozygous variants of CaSR gene, one patient had a heterozygous variant of AP2S1 gene. 1 case underwent total parathyroidectomy, followed by calcium supplementation, 3 cases received salmon calcitonin treatment, and 2 cases accepted low calcium diet, blood calcium levels were all controlled well. In conclusion, CaSR signaling pathway related hypercalcemia is rare. Gene detection is essential for children with hypercalcemia. Familial hypocalcemia hypercalcemia (FHH) can be effectively treated with salmon calcitonin.

Objective:To corelate thromboelastography (TEG)-related parameters and D-dimer and fibrinogen levels with the severity of preeclampsia and pregnancy outcomes in patients with preeclampsia.Methods:A case-control study was conducted involving 92 patients with preeclampsia who received treatment at Northwest Women's and Children's Hospital between March 2022 and September 2023 (patient group) and 92 healthy pregnant women who underwent routine check-ups during the same period (control group). All participants underwent TEG tests, and D-dimer and fibrinogen levels were measured. Intergroup comparisons were performed, and patients were categorized based on the severity of their condition. TEG parameters and D-dimer and fibrinogen levels were compared among patients with varying severities of preeclampsia. TEG-related parameters were correlated with D-dimer and fibrinogen levels. Adverse pregnancy outcomes in the patient group were statistically analyzed, and risk factors for these adverse outcomes in women with preeclampsia were identified.Results:In the patient group, the R and K values were (3.06 ± 0.36) minutes and (1.21 ± 0.14) minutes, respectively, both of which were significantly lower than those in the control group [(5.44 ± 0.61) minutes, (1.79 ± 0.21) minutes, t = 32.22, 22.04, both P < 0.001]. The α angle, CI value, MA value, and D-dimer and fibrinogen levels in the patient group were (71.31 ± 7.63)°, (3.89 ± 0.41), (65.71 ± 7.01) mm, (2.22 ± 0.24) mg/L, and (4.51 ± 0.49) g/L, respectively, all of which were significantly higher than those in the control group [(64.85 ± 6.79)°, (2.19 ± 0.23), (58.96 ± 6.09) mm, (1.92 ± 0.21) mg/L, (3.75 ± 0.40) g/L, t = -6.06, -34.68, -6.97, -9.02, -11.52, all P < 0.001]. In the patient group, severe cases had significantly lower R and K values compared with mild cases, while the α angle, CI value, MA value, and D-dimer and fibrinogen levels were significantly higher in severe cases than in mild cases ( t = 11.06, 7.16, -8.01, -12.05, -3.91, -13.74, -8.269, all P < 0.001). In patients with preeclampsia, the R and K values were negatively correlated with D-dimer levels, and the R value was negatively correlated with fibrinogen level ( r = -0.504, -0.612, -0.493, all P < 0.05). In addition, the MA and CI values were positively correlated with D-dimer level, and the α angle was positively correlated with fibrinogen level ( r = 0.436, 0.534, 0.492, all P < 0.05). Among the participants, 41 women experienced adverse pregnancy outcomes. In patients with adverse pregnancy outcomes, the R and K values were (2.48 ± 0.25) minutes and (1.12 ± 0.14) minutes, which were significantly lower than those in patients without adverse pregnancy outcomes [(2.75 ± 0.29) minutes, (1.28 ± 0.13) minutes, t = 4.71, 5.67; both P < 0.001]. The α angle, CI value, MA value, and D-dimer and fibrinogen levels in patients with adverse pregnancy outcomes were (76.62 ± 8.01)°, (4.42 ± 0.46), (69.77 ± 7.06) mm, (2.57 ± 0.27) mg/L, and (4.97 ± 0.51) g/L, all of which were significantly higher than those in patients without adverse pregnancy outcomes [(67.04 ± 7.01)°, (3.46 ± 0.37), (62.45 ± 6.82) mm, (1.94 ± 0.21) mg/L, (4.14 ± 0.43) g/L, t = -6.11, -5.03, -11.09, -12.25, -8.46, all P < 0.001]. Logistic regression analysis indicated that R and K values were protective factors for adverse pregnancy outcomes ( OR < 1, P < 0.05), while MA value, α angle, CI value, and D-dimer and fibrinogen levels were independent risk factors ( OR > 1, P < 0.05). Conclusion:TEG-related parameters differ significantly between patients with preeclampsia and healthy pregnant women. These parameters are correlated with the severity of preeclampsia, as well as with D-dimer and fibrinogen levels. TEG-related parameters are risk factors for adverse pregnancy outcomes in patients with preeclampsia.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.

Objective To understand the distribution and changing resistance profiles of clinical isolates of Enterococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Enterococcus according to the unified protocol of CHINET program by automated systems,Kirby-Bauer method,or E-test strip.The results were interpreted according to the Clinical & Laboratory Standards Institute(CLSI)breakpoints in 2021.WHONET 5.6 software was used for statistical analysis.Results A total of 124 565 strains of Enterococcus were isolated during the 7-year period,mainly including Enterococcus faecalis(50.7％)and Enterococcus faecalis(41.5％).The strains were mainly isolated from urinary tract specimens(46.9％±2.6％),and primarily from the patients in the department of internal medicine,surgery and ICU.E.faecium and E.faecalis strains showed low level resistance rate to vancomycin,teicoplanin and linezolid(≤3.6％).The prevalence of vancomycin-resistant E.faecalis and E.faecium was 0.1％and 1.3％,respectively.The prevalence of linezolid-resistant E.faecalis increased from 0.7％in 2015 to 3.4％in 2021,while the prevalence of linezolid-resistant E.faecium was 0.3％.Conclusions The clinical isolates of Enterococcus were still highly susceptible to vancomycin,teicoplanin,and linezolid,evidenced by a low resistance rate.However,the prevalence of linezolid-resistant E.faecalis was increasing during the 7-year period.It is necessary to strengthen antimicrobial resistance surveillance to effectively identify the emergence of antibiotic-resistant bacteria and curb the spread of resistant pathogens.
