Objective This study aimed to explore the relationships between residential greenness and cardiometabolic risk factors among rural adults in Xinjiang Uygur Autonomous Region(Xinjiang)and thus provide a theoretical basis and data support for improving the health of residents in this region. Methods We recruited 9,723 adult rural residents from the 51st Regiment of the Third Division of the Xinjiang Production and Construction Corps in September 2016.The normalized difference vegetation index(NDVI)was used to estimate residential greenness.The generalized linear mixed model(GLMM)was used to examine the association between residential greenness and cardiometabolic risk factors. Results Higher residential greenness was associated with lower cardiometabolic risk factor prevalence.After adjustments were made for age,sex,education,and marital status,for each interquartile range(IQR)increase of NDVI500-m,the risk of hypertension was reduced by 10.3%(OR=0.897,95%CI=0.836-0.962),the risk of obesity by 20.5%(OR=0.795,95%CI=0.695-0.910),the risk of type 2 diabetes by 15.1%(OR=0.849,95%CI=0.740-0.974),and the risk of dyslipidemia by 10.5%(OR=0.895,95%CI=0.825-0.971).Risk factor aggregation was reduced by 20.4%(OR=0.796,95%CI=0.716-0.885)for the same.Stratified analysis showed that NDVI500-m was associated more strongly with hypertension,dyslipidemia,and risk factor aggregation among male participants.The association of NDVI500-m with type 2 diabetes was stronger among participants with a higher education level.PM10 and physical activity mediated 1.9%-9.2%of the associations between NDVI500-m and obesity,dyslipidemia,and risk factor aggregation. Conclusion Higher residential greenness has a protective effect against cardiometabolic risk factors among rural residents in Xinjiang.Increasing the area of green space around residences is an effective measure to reduce the burden of cardiometabolic-related diseases among rural residents in Xinjiang.

Objective:To explore the role of metagenomic next-generation sequencing (mNGS) in the diagnosis of pathogens in primary infectious diseases of the spine (IDS) and to reveal its pathogen spectrum.Methods:This is a retrospective multi-center case series study. Clinical data of 380 patients with primary IDS who were treated at four medical centers in China from December 2019 to April 2024 were retrospectively analyzed. Among them, 82 cases were from the Department of Spine Surgery at the Affiliated Hospital of Qingdao University, 129 cases were from the Orthopedics Section Ⅱ (Bone Infection), Public Health Clinical Center Affiliated to Shandong University, 112 cases were from the Department of Spine Surgery, Fuzhou Second General Hospital, and 57 cases were from the Department of Orthopedic Surgery, Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. There were 238 males and 242 females, with an age of (61.4±13.1) years (range: 10 to 91 years). Specimens from the site of spinal infection were obtained for pathogen culture, pathological examination, and mNGS detection preoperatively or intraoperatively in all patients. The number, types, and positive rates of pathogens detected by the two methods were analyzed and compared using the Chi-square test.Results:Among the 380 patients, 320 had confirmed pathogenic bacteria, with the highest proportion being pyogenic bacterial infections, accounting for 76.9% (246/320). The most common pathogen was Staphylococcus aureus, accounting for 22.8% (73/320). Brucella accounted for 13.8% (44/320); Mycobacterium tuberculosis accounted for 6.3% (20/320). Fungal infections accounted for 3.4% (11/320), mainly Aspergillus and Candida. In addition, Mycoplasma was detected in 3 cases (0.9%) and Benacox body in 4 cases (1.2%). The pathogen spectrum constructed by mNGS covered 46 types of pathogens, higher than the 22 types detected by traditional methods. The positive rate of mNGS was 80.8% (308/381), significantly higher than the 27.9% (106/381) of traditional methods ( χ2=182.53, P<0.01). Conclusions:mNGS improves the positive rate of pathogen diagnosis in IDS, detecting a broader spectrum of pathogens, and serves as a valuable complement to traditional diagnostic methods. Combining both methods in the diagnosis of IDS can maximize detection rates, providing robust evidence for precise anti-infective treatment.

Background::A phase II trial on recombinant human tenecteplase tissue-type plasminogen activator (rhTNK-tPA) has previously shown its preliminary efficacy in ST elevation myocardial infarction (STEMI) patients. This study was designed as a pivotal postmarketing trial to compare its efficacy and safety with rrecombinant human tissue-type plasminogen activator alteplase (rt-PA) in Chinese patients with STEMI.Methods::In this multicenter, randomized, open-label, non-inferiority trial, patients with acute STEMI were randomly assigned (1:1) to receive an intravenous bolus of 16 mg rhTNK-tPA or an intravenous bolus of 8 mg rt-PA followed by an infusion of 42 mg in 90 min. The primary endpoint was recanalization defined by thrombolysis in myocardial infarction (TIMI) flow grade 2 or 3. The secondary endpoint was clinically justified recanalization. Other endpoints included 30-day major adverse cardiovascular and cerebrovascular events (MACCEs) and safety endpoints.Results::From July 2016 to September 2019, 767 eligible patients were randomly assigned to receive rhTNK-tPA ( n = 384) or rt-PA ( n = 383). Among them, 369 patients had coronary angiography data on TIMI flow, and 711 patients had data on clinically justified recanalization. Both used a –15% difference as the non-inferiority efficacy margin. In comparison to rt-PA, both the proportion of patients with TIMI grade 2 or 3 flow (78.3% [148/189] vs. 81.7% [147/180]; differences: –3.4%; 95% confidence interval [CI]: –11.5%, 4.8%) and clinically justified recanalization (85.4% [305/357] vs. 85.9% [304/354]; difference: –0.5%; 95% CI: –5.6%, 4.7%) in the rhTNK-tPA group were non-inferior. The occurrence of 30-day MACCEs (10.2% [39/384] vs. 11.0% [42/383]; hazard ratio: 0.96; 95% CI: 0.61, 1.50) did not differ significantly between groups. No safety outcomes significantly differed between groups. Conclusion::rhTNK-tPA was non-inferior to rt-PA in the effect of improving recanalization of the infarct-related artery, a validated surrogate of clinical outcomes, among Chinese patients with acute STEMI.Trial registration::www.ClinicalTrials.gov (No. NCT02835534).

Objective To compare the clinical efficacy of 25G+and 27G+pars plana vitrectomy(PPV)in the treat-ment of idiopathic epiretinal membrane(iERM).Methods A total of 50 iERM patients(50 eyes)who were admitted to the Third Affiliated Hospital of Xinxiang Medical University from December 2019 to August 2022 were selected as the research subjects.These patients were divided into the control group and observation group based on different surgical methods,with 25 patients(25 eyes)in each group.Patients in the control group received 25G+PPV treatment,while patients in the observation group received 27G+PPV treatment.The surgical duration and postoperative 1-day incision subconjunctival hemorrhage and e-dema of patients in two groups were compared;central macular thickness(CMT)was measured by optical coherence tomo-graphy before surgery,1 day,1 week,1 month,and 3 months postoperatively in the two groups.Visual acuity of patients in both groups was assessed according to the early treatment diabetic retinopathy study(ETDRS)visual acuity chart.Intraocular pressure was measured by using a non-contact Callon tonometer.Complications,such as intraoperative macular injury,retinal hole,postoperative choroidal detachment,retinal hemorrhage,retinal detachment,and intraocular infection,were observed in both groups.Results The surgical duration of patients in the observation group was significantly shorter than that in the control group(t=2.314,P＜0.05).The extent of subconjunctival hemorrhage and edema of patients in the observation group was significantly smaller than that in the control group(t=13.706,P＜0.01).The ETDRS visual acuity of patients at 1 day,1 week,1 month,and 3 months after surgery in both groups was significantly higher than that before surgery(P＜0.05).There was no signifi-cant difference in ETDRS visual acuity of patients between the two groups at 1 day,1 week,1 month,and 3 months postoperatively(P＞0.05).At 1 day after surgery,the intraocular pressure of patients in the observation group was significantly higher than that in the control group(P＜0.05).At 1 week,1 month,and 3 months after surgery,there was no significant difference in intraocular pressure of patients between the two groups(P＞0.05).Two patients in the control group experienced transient ocular hypotension 1 day after surgery,while no such complication was observed in the observation group.Patients in both groups presented with varying degrees of retinal nerve epithelial layer traction,retinal edema,thickening,and vascular distortion before surgery.At 1 day after surgery,epiretinal membrane traction was relieved in both groups,and there was a significant improvement in the anatomical structure of the macular area compared to preoperative conditions.At 1 day,1 week,1 month,and 3 months after surgery,the CMT of patients in both groups was reduced compared to preoperative values(P＜0.05);there was no significant difference in CMT of patients between the two groups at 1 day,1 week,1 month,and 3 months after surgery(P＞0.05).In the control group,18 eyes(72.0％)were sutured at the scleral puncture sites due to leakage,while no suturing was performed in the observation group.Patients in both groups completed the surgery successfully,without any intraoperative complications such as macular injury or retinal hole.During the 3-month follow-up,no postoperative complications such as choroidal detachment,retinal hemorrhage,retinal detachment,or intraocular infection were observed in both groups.Conclusion Both 27G+PPV and 25G+PPV have good clinical effects and high surgical safety in the treatment of iERM.Compared with 25G+PPV,27G+PPV can shorten the surgical duration,better maintain postoperative intraocular pressure stability,and reduce the range of subconjunctival bleeding and edema.

Objective To observe the dynamic changes of cardiac lymphangiogenesis in Doxorubicin(DOX)-induced dilated cardiomyopathy(DCM)model mice,and to study the the protective mechanism of Kuoxin Decoction.Methods The DCM mouse model was established by intraperitoneal injection of DOX,and the dynamic observation was performed every week.On this basis,60 C57BL/6 mice were randomly divided into 6 groups(n=10):control group,Model group,L-KXD,M-KXD and H-KXD groups and Captopril group.After successful modeling,the KXD and the positive control drug Captopril were administered continuously for 28 days.Echocardiography was used to detect cardiac function in mice,HE staining and Masson staining were used to observe pathological and morphological changes of the heart,Whole-mount immunofluorescent staining was used to detect the expression of LYVE-1 and Podoplanin in epicardial lymphatic vessels,Western blot was used to detect the expression of VEGFR-3 protein,and qPCR was used to detect the expression of VEGFR-3 mRNA.Results DCM mice induced by DOX showed significant cardiac function decline from the third week(DOX:15 mg·kg-1,P<0.05),and significant ventricular remodeling at the fifth week(DOX:15 mg·kg-1,P<0.01);The lymphatic vessel area of the mouse heart decreased significantly from the fourth week(DOX:20 mg·kg-1,P<0.0001),and the expression of VEGFR-3 decreased significantly from the third week(DOX:15 mg·kg-1,P<0.01).Conclusion KXD can improve ventricular remodeling and cardiac function in DOX-induced DCM mice,promote cardiac lymphangiogenesis,and upregulate the expression of VEGFR-3 at protein and mRNA levels,with a better effect than captopril.DOX-induced cardiac lymphangiogenesis in DCM mice leads to severe myocardial fibrosis and weakened cardiac function,which gradually worsens with the accumulation of modeling time and dose.KXD can promote cardiac lymphangiogenesis and improve cardiac function in DOX-induced DCM mice.The mechanism may be related to the up-regulation of VEGFR-3 expression.

The retrieval time limit was from the establishment of the database to April 2022. Two researchers independently evaluated the included literature and extracted the literature that met the quality standards.Results:Totally 12 articles were included at last, including 5 guidelines, 3 expert consensus and 4 Meta-analysis. From the six dimensions of the necessity and risk factors of recurrence prevention in diabetic foot patients, decompression brace prevention, surgery and wound management prevention, nutritional therapy prevention, health education and lifestyle prevention, monitoring and analysis, 18 pieces of best evidence were summarized.Conclusions:The best evidence for the prevention of recurrence of diabetic foot patients was summarized to provide evidence-based basis for management decision makers and decision implementers to prevent recurrence of diabetic foot. In the process of practice, medical workers should also fully evaluate the promoting factors and hindering factors in order to ensure that evidence can be better applied to clinical practice and serve patients.

Objective To analyze the application of intelligent speech follow-up system in sec-ondary prevention of ischemic stroke(IS).Methods A total of 842 IS patients who received intra-venous thrombolysis were randomly divided into intelligent group and artificial group.In the artificial group,corresponding intelligent follow-up templates were developed for the main risk factors affecting the occurrence of IS.The intelligent follow-up system determined the follow-up time and period ac-cording to the reserved information of patients when they were discharged,automatically called out the patients'home conditions for follow-up,and converted the response contents into text mode for out-put.The artificial group was followed up by professionally trained nursing staff,and the follow-up con-tent was the same as that of the intelligent group.Call out,hypertension,diabetes,medication,exer-cise,average call time and satisfaction of follow-up in the two groups were collected.Results The tel-ephone connection rates showed no statistical significances between two groups(P＞0.05).During the follow-up calls,the correct recognition rate of follow-up contents in the intelligent group was low-er,and therateof unwillingness to cooperate and call interruption rate were higher than those in the control group(P＜0.05).There were no statistically significant differences in the percentages of au-tomatic message leaving,inconvenient answering,resident death,family members unable to answer and number error between the two groups(P＞0.05),and there was no statistical significance in the distribution of disconnected calls between the two groups(P＞0.05).In the effective follow-up calls,there was no statistical significance in the answers to questions related to hypertension and diabetes,compliance and exercise between the two groups(P＞0.05).The average call duration in the intel-ligent group was significantly shorter,and follow-up satisfaction was lower than that in the control group(P＜0.05).Conclusion Intelligent voice follow-up system can replace manual telephone follow-up to a certain extent,and help medical staff understand the compliance of home blood pres-sure,blood sugar,medication,exercise and secondary prevention in IS patients,and can save fol-low-up time and improve follow-up efficiency compared with manual follow-up,but its language rec-ognition and improvement of cooperation rate still need to be optimized.
