ObjectiveTo evaluate the clinical efficacy and safety of Jingmaiyan granules （composed of Lonicerae Japonicae Flos， Sedi Herba， Paeoniae Radix Rubra， Moutan Cortex， Rhei Radix et Rhizoma Praeparata， and Glycyrrhizae Radix et Rhizoma） combined with external application of Jinhuang Ointment in treating acute-stage blood heat stasis type superficial thrombophlebitis （ST） of lower extremities， and to explore their effects on hemorheology and serum inflammatory factors. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 124 patients with lower extremity ST were randomized into two groups（62 cases in each group）. The control group received external application of Jinhuang ointment and oral placebo treatment， while the observation group received external application of Jinhuang ointment and oral Jingmaiyan granules. Both groups were treated for 2 weeks. The clinical symptom scores， therapeutic efficacy of traditional Chinese medicine （TCM） syndrome， pain visual analog scale （VAS） scores， hemorheological indices ［including whole blood high-shear， medium-shear， and low-shear viscosity， as well as plasma viscosity （PV）］， and inflammatory factors ［C-reactive protein （CRP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）］ were compared before and after treatment. ResultsAfter 2 weeks of treatment， the total effective rate in the observation group （98.3%， 60/62） was significantly higher than that in the control group （83.8%， 52/62）， with a statistically significant difference （Z=3.512 1， P<0.05）. Compared with pre-treatment scores， the scores for skin color， skin temperature， swelling， pain， and cord or nodules were significantly reduced in both groups （P<0.05）， with more pronounced improvement in the observation group （P<0.05）. Additionally， compared with pre-treatment levels， the whole blood viscosity （low-， medium-， and high-shear） significantly improved in both groups after treatment （P<0.05）， with more marked improvement in the observation group （P<0.05）. Furthermore， the plasma viscosity， CRP， IL-6， and TNF-α levels were significantly reduced in both groups after treatment （P<0.05）， with more pronounced improvement observed in the observation group （P<0.05）. ConclusionThe combination of external application of Jinhuang ointment and oral Jingmaiyan granules effectively improves clinical symptoms， hemorheological abnormalities， and inflammatory responses in patients with acute stage blood heat stasis type ST of lower extremities. The treatment is safe and holds clinical promotion value.

Objective: To explore the association of screening myopia and sitting posture habits as well as screen viewing distance among primary school students, providing a scientific basis for myopia prevention and intervention among primary school students. Methods: From April to June 2024, a convenient sampling method was used to enroll 1 394 fourth grade students from four primary schools in a district of Beijing for vision examinations and questionnaire surveys. Logistic regression models were employed to analyze the relationship of screening myopia detection and sitting posture habits as well as viewing distance. Results: The screening myopia prevalence among primary school students was 63.8%. About 13.1% of students self reported poor sitting posture, and 47.1% selfreported a viewing distance of ≤20 cm. After adjusting for covariates including age, gender, school, sleep quality, parental myopia status, physical fitness level, daily high intensity physical activity, weekend outdoor activity time and types of after school services, Logistic regression analysis showed that students with poor sitting posture were more likely to have screening myopia than those with normal sitting posture ( OR =1.73,95% CI =1.03-2.92); students with a viewing distance of ≤20 cm were more likely to have screening myopia than those with a viewing distance of >20 cm( OR =1.32, 95% CI =1.02-1.71)( P <0.05). The association between sitting posture and screening myopia was more significant among boys( OR =2.00, 95% CI =1.03-3.88, P < 0.05 ). A multiplicative interaction was observed between sitting posture and viewing distance. Compared to primary school students with normal posture and a viewing distance of >20 cm, those with poor posture and a viewing distance of >20 cm were more likely to have screening myopia ( OR =1.82, 95% CI =1.12-2.96， P <0.05). Conclusions Both sitting posture habits and screen viewing distance are related to screening myopia in primary school students. Poor sitting posture poses a higher risk than screen distance, and the two factors exhibit an interactive effect on myopia risk.

ObjectiveTo observe the effects of the Fuyuan Tongluo prescription （composed of Astragali Radix， Carthami Flos， Spatholobi Caulis， Liquidambaris Fructus， Lycopodii Herba， Centellae Herba， etc.） in the treatment of restenosis with collateral obstruction syndrome after interventional operation of lower limb arteriosclerosis obliterans， and its impact on the primary patency rate. MethodsA total of 88 patients with collateral obstruction syndrome after interventional surgery for lower limb arteriosclerosis obliterans were randomly divided into two groups. The control group （n₁=44） received dual antiplatelet therapy with aspirin and clopidogrel. The observation group （n₂=44） was treated with Fuyuan Tongluo prescription non-decocted granules in addition to aspirin and clopidogrel. Both groups received treatment for 24 weeks and were followed up for 36 weeks. The changes in primary patency rate， symptom scores， ankle-brachial index （ABI）， coagulation function， and inflammatory markers before and after treatment were compared between the two groups. ResultsFor primary patency rate， after 36 weeks of treatment， the observation group had a significantly better primary patency rate than the control group （χ²=4.14，P<0.05）. After 24 weeks of treatment， there was no significant difference in primary patency rate between the two groups. Clinical efficacy comparison： Based on symptom quantification scores， and using the Nimodipine method as a reference， the overall efficacy of the observation group was superior to that of the control group after 24 weeks of treatment （χ²=2.24，P<0.05）. ABI levels： The observation group had a higher ABI than the control group after 24 and 36 weeks of treatment （P<0.05）. Coagulation function indicators： After 24 and 36 weeks of treatment， D-dimer and fibrinogen levels in both groups were lower than before treatment （P<0.05）. Inflammatory markers： After 24 and 36 weeks of treatment， CRP levels in the observation group were lower than those in the control group （P<0.05）. There were no significant differences in white blood cell （WBC） and erythrocyte sedimentation rate （ESR） levels before and after treatment between the two groups. ConclusionAdding Fuyuan Tongluo prescription non-decocted granules to dual antiplatelet therapy can improve the primary patency rate of the affected vessels in patients with lower limb arteriosclerosis obliterans after interventional surgery. Longer use of Fuyuan Tongluo prescription can significantly improve clinical symptoms， demonstrating clinical application value.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective To explore the differences between various monitoring methods of anesthetic depth during total knee arthroplasty under general anesthesia combined with ultrasound-guided femoral nerve block.Methods From January 2021 to March 2021,60 patients undergoing total knee arthroplasty under ultrasound-guided femoral nerve block combined with general anesthesia were randomly divided into IoC group and BIS group,30 cases in each group.IoC group awareness index(Index of Consciousness,IoC)monitoring;bIS group was monitored by bispectral index(BIS)to guide the use of sedative and analgesic drugs during operation.The primary outcome measure was the time of first eye opening,and the secondary outcome measures included the average target concentration of sedative and analgesic drugs during operation,the number of perioperative adverse events and the quality of recovery.Results The average difference in the first eye opening time between the two groups was 1.57 min(95％confidence interval:-0.61～2.63).The upper limit of the 95％confidence interval was 2.63 min,which was less than the non-inferiority boundary value(δ=2.8 min),suggesting that the non-inferiority hypothesis of the main efficacy indicators was established.There was no significant difference in the dosage of propofol and sufentanil and the quality of recovery between the two groups(P＞0.05).The target-controlled concentration of remifentanil in IoC group(8.55±1.45)ng/ml was significantly higher than that in BIS group(4.62±0.96)ng/ml,and the difference was statistically significant(P＜0.05).At the same time,compared with BIS group,the number of stress hypertension(10 vs 32)in IoC group was significantly reduced and the number of bradycardia(17 vs 6)was significantly increased,the difference was statistically significant(P＜0.05).At the same time,no intraoperative awareness and body movement were found in both groups.Conclusion During total knee arthroplasty surgery under general anesthesia combined with ultrasound-guided femoral nerve block:1.IoC monitoring is not inferior to BIS monitoring in terms of awakening speed and quality.2.The increased use of remifentanil in the IoC group and the reduced incidence of hypertension may indicate that IoC monitoring is more sensitive to intraoperative nociceptive stimuli.

Objective:To investigate the impact of coronary angiography-derived index of microcirculatory resistance (caIMR) on the long-term prognosis of patients with coronary heart disease (CHD) undergoing elective percutaneous coronary intervention (PCI).Methods:The study was a retrospective cohort study conducted at a single centre. Patients who successfully underwent elective PCI with pre-and post-PCI caIMR measurements in Peking University First Hospital between August 2013 and December 2020 were included. Then patients were categorised into three groups based on pre-and post-PCI caIMR: post-PCI caIMR<25 U group, pre-PCI caIMR<25 U and post-PCI caIMR≥25 U group, and both pre-and post-PCI caIMR≥25 U group. Collected clinical data of patients, including comorbid diabetes mellitus.The primary endpoint was a composite endpoint, defined as a composite of all-cause death, non-fatal myocardial infarction, and any revascularisation. The association between caIMR-based groupings and clinical outcomes was analysed using Cox proportional hazards regression models.Results:A total of 625 patients who underwent successful elective PCI were included in the study, among whom 294 (47.0%) had stable angina. The age was (64.5±10.1) years, and 440 (70.4%) patients were male. Over a median follow-up of 3.69 (1.80, 5.80) years, 122 patients (19.5%) experienced composite endpoint events. Post-PCI caIMR≥25 U in combination with diabetes mellitus was associated with an increased risk of the composite endpoint compared to those with post-PCI caIMR<25 U and without diabetes mellitus (adjusted HR=2.13, 95% CI 1.17-3.88, P=0.014). In the combined analysis, compared with post-PCI caIMR<25 U group, those with both pre-and post-PCI caIMR≥25 U had higher risks of composite endpoint (adjusted HR=2.01, 95% CI 1.18-3.43, P=0.010) and any revascularisation (adjusted HR=2.12, 95% CI 1.17-3.84, P=0.013). The pre-PCI caIMR<25 U and post-PCI caIMR≥25 U group showed no statistically significant differences in any of the endpoints compared to post-PCI caIMR<25 U group. Conclusions:Integrated pre-and post-procedural assessment of caIMR may enhance risk stratification in patients with coronary heart disease. Persistent coronary microvascular dysfunction present both before and after PCI, as measured by caIMR, serves as an independent risk factor for adverse events in patients with coronary heart disease undergoing elective PCI.

Objective To explore practical pathways for the connotation quality control of Zhuang medical records by le-veraging the reform of DRG-based medical insurance payment systems as an opportunity,thereby enhancing record quality and fostering the coordinated development of ethnic medicine with modern medical insurance payment systems.Methods By analy-zing the requirements imposed by the DRG-based payment reform on the quality management of Zhuang medical records,a quality control management system focused on the connotation quality control of these records was established.A scoring standard for the connotation quality of Zhuang medical records,supplemented by DRG,was developed.Dynamic quality control was implemented through a combination of information-based intelligent review and expert manual review to ensure rectification.Results Key in-dicators,such as the qualification rate of the first page of medical records,the A-level rate of inpatient records,and the DRG en-rollment rate,showed significant improvements.The documentations of surgical and procedural records were standardized,and the records of ward rounds and case discussions by senior physicians were comprehensive and detailed,accurately reflecting the diagnostic and therapeutic methods and outcomes of Zhuang medicine.Conclusion The DRG-based quality control model for Zhuang medical records effectively aligns medical insurance payment with the unique characteristics of ethnic medicine,offering a replicable model for the quality management of medical records in ethnic medicine institutions under DRG-based reforms.
