BACKGROUND:Percutaneous curved vertebroplasty has the advantages of minimal trauma and bone cement dispersion,but whether it is safe and effective for the treatment of compression fractures in the upper 1/3 of the vertebral body needs further study.OBJECTIVE:To investigate the clinical efficacy of percutaneous curved vertebroplasty in the treatment of the upper 1/3 compression fractures of the osteoporotic vertebrae.METHODS:Medical records of 66 patients with osteoporotic thoracolumbar upper 1/3 compression fracture admitted to Department of Orthopedics of PLA Rocket Force Characteristic Medical Center from January 2020 to June 2023 were retrospectively analyzed.Among them,32 cases were treated with percutaneous curved vertebroplasty(observation group)and 34 cases were treated with"noncoplanar bipedicular puncture"percutaneous vertebroplasty(control group).Pain visual analog scale score,Oswestry Disability Index,anterior edge height of injured vertebra,and Cobb angle of injured vertebra were compared and analyzed between the two groups before surgery,the first day after surgery,and the last follow-up.The operative time,bone cement leakage rate,bone cement injection volume,and bone cement dispersion score of the two groups were statistically analyzed.RESULTS AND CONCLUSION:(1)The operations were successfully completed in both groups of patients,and no complications such as bone cement allergy,bone cement embolism,nerve damage,or epidural hematoma occurred.(2)Pain visual analog scale score,Oswestry disability index,anterior edge height,and Cobb angle of injured vertebra of the two groups at the first day after surgery and the last follow-up were all better than those before surgery,with statistically significant difference(P＜0.05),but there was no statistical significance between the two groups(P＞0.05).The Oswestry disability index of the two groups at the last follow-up was better than that on the first day after surgery(P＜0.05).(3)The operation time and bone cement leakage rate of the observation group were lower than those of the control group,and the differences were statistically significant(P＜0.05).(4)There were no significant differences in bone cement injection volume and bone cement dispersion score between the two groups(P＞0.05).(5)The results show that percutaneous curved vertebroplasty in the treatment of osteoporotic vertebrae compression fractures in the upper 1/3 of the vertebral body can effectively relieve pain,maintain vertebral height,and reduce operative time and bone cement leakage rate.

By using a strategy of leveraging the ability of metal-organic frameworks(MOFs)materials to precisely regulate the spatial orientation of cyclodextrins(CD),a polystyrene-modified γ-cyclodextrin metal-organic frameworks(PS-CD-MOFs)capillary coating was established and applied to the chiral separation of amino acids in open-tubular capillary electrochromatography(OT-CEC)based on the excellent film-forming property of polystyrene(PS).Characterization results by Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD)indicated that PS was successfully grafted onto the surface of CD-MOFs.The modification significantly improved the structural stability and thermal stability of CD-MOFs while maintaining the integrity of the MOFs.The PS-CD-MOFs coated capillary electrophoresis system exhibited excellent performance in separating dansylated amino acid enantiomers(Dns-D,L-AAs).Specifically,under the optimal separation conditions(Sodium dodecyl sulfate/boric acid buffer system,20 cm capillary,and 10 kV effective voltage),good separation was achieved for D,L-methionine(D,L-Met)and D,L-serine(D,L-Ser).Further quantitative analysis showed that Dns-D,L-Met presented a good linear relationship in the concentration range of 10.0-1500.0 μmol/L,with a correlation coefficient close to 0.998,demonstrating high sensitivity and repeatability.Not only did it overcome the problem that traditional CD(used as additives in capillary electrophoresis)could not precisely control the spatial orientation of chiral resolvents,but also it solved the issues of insufficient stability and bonding amount of CD-MOFs coatings by utilizing the excellent film-forming property of polymers on the inner wall of capillaries.This study provided an efficient and controllable new strategy for construction of chiral separation stationary phases.

Objective To investigate the relationship between chromosomal karyotypes and reproductive factor levels in peripheral blood and adverse pregnancies in women.Methods A total of 105 pregnant women who received prenatal care and delivered at Yulin Hospital,the First Affiliated Hospital of Xi'an Jiaotong Uni-versity and Yulin Traditional Chinese Medicine Hospital from January 2020 to June 2024 were selected as the research subjects.Through the follow-up observation of pregnant women,there were 29 cases of pregnant women with adverse pregnancies(adverse pregnancy group)and 76 cases of pregnant and parturient women with normal pregnancies(good pregnancy group).The karyotypes of peripheral blood chromosomes and the levels of reproductive factors,as well as their correlations with adverse pregnancy outcomes,were analyzed re-spectively in the adverse pregnancy group and the good pregnancy group.Results There was a statistically significant difference in the proportion of autosomes and sex chromosomes in the number and structure of pe-ripheral blood between the adverse pregnancy group and the good pregnancy group(P＜0.05).The anti-Müllerian hormone(AMH)level in the adverse pregnancy group was higher than that in the good pregnancy group,while estradiol(E2)and progesterone(P)levels were lower than those in the good pregnancy group,and the differences were statistically significant(P＜0.05).Abnormalities in autosomal number,autosomal structure,sex chromosome number,sex chromosome structure,and AMH were all positively correlated with adverse pregnancy outcomes(r=0.369,0.445,0.528,0.665,0.785,P＜0.05).E2 and P were negatively cor-related with adverse pregnancy outcomes(r=-0.865,—0.562,P＜0.05).Conclusion Peripheral blood chromosomal karyotypes and reproductive factor levels are related to adverse pregnancies in women.By under-standing the relationship between these biomarkers and chromosomal abnormalities,adverse pregnancy out-comes can be better predicted and managed,and the accuracy of fertility treatment can be improved.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

BACKGROUND: There is a gap in understanding the effects of different acupoints and treatment methods (acupuncture and moxibustion) on microcirculatory changes in the lumbar region. OBJECTIVE: This study aimed to assess the thermal effects of acupuncture at Weizhong (BL40), with acupuncture at Chize (LU5) and moxibustion at both acupoints as control interventions. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: In this randomized controlled trial, 140 healthy participants were equally divided into four groups: acupuncture at BL40 (Acu-BL40), acupuncture at LU5 (Acu-LU5), moxibustion at BL40 (Mox-BL40) and moxibustion at LU5 (Mox-LU5). Participants underwent a 30-minute session of their assigned treatment. Infrared thermal imaging was used to collect temperature data on the areas of interest for analysis. MAIN OUTCOME MEASURES: The primary measure was the change in average temperature of the observed area after the intervention. The secondary measures included periodic temperature changes every 5 min and the temperature changes of the Governor Vessel and Bladder Meridian in the observed area after the intervention. RESULTS: Significant interactions were observed between treatments and acupoints affecting temperature (P < 0.001). The Acu-BL40 group showed a notably higher increase in mean temperature after 30 min compared to the Acu-LU5 and Mox-BL40 groups, with increases of 0.29 (95% confidence interval [CI] = 0.17 to 0.41) and 0.24 (95% CI = 0.08 to 0.41) °C, respectively. CONCLUSION: Acupuncture at BL40 acupoint can significantly increase the mean temperature in the observed area, highlighting the specific thermal effect of acupuncture compared to moxibustion in the lumbar area. This suggests a potential therapeutic benefit of acupuncture at BL40 for managing lumbar conditions. TRIAL REGISTRATION ClinicalTrials.gov (NCT05665426).

OBJECTIVE: To compare the effectiveness of different puncture methods of the flexible bone cement delivery device in unilateral percutaneous curved vertebroplasty for osteoporotic vertebral upper 1/3 compression fractures. METHODS: A retrospective analysis was conducted on the clinical data of 67 patients with osteoporotic vertebral upper 1/3 compression fractures who were admitted and met the selection criteria between January 2023 and April 2024. The patients were divided into two groups based on the puncture method of the flexible bone cement delivery device: the oblique puncture group ( n=37) and the parallel puncture group ( n=30). There was no significant difference ( P>0.05) between the two groups in terms of gender, age, bone mineral density (T value), distribution of fractured vertebrae, time from injury to operation, and preoperative visual analogue scale (VAS) score for pain, Oswestry disability index (ODI), anterior vertebral height of the fractured vertebra, and Cobb angle of the fractured vertebra. The following parameters were compared between the two groups: operation time, incidence of secondary puncture, incidence of bone cement leakage, volume of injected bone cement, bone cement distribution score, as well as VAS score, ODI, anterior vertebral height of the fractured vertebra, and Cobb angle of the fractured vertebra at 1 day after operation and at last follow-up. RESULTS: Two cases in the oblique puncture group and 7 cases in the parallel puncture group underwent secondary puncture during operation, and the difference in the incidence of secondary puncture was significant ( P<0.05). No complications such as bone cement hypersensitivity, bone cement embolism, nerve injury, or epidural hematoma occurred in both groups. There was no significant difference in operation time, volume of injected bone cement, incidence of bone cement leakage, distribution score and rating of bone cement between the two groups ( P>0.05). All patients were followed up 6-18 months (mean, 12.0 months), and there was no significant difference in the follow-up time between the two groups ( P>0.05). No further fracture collapse or compression occurred in the fractured vertebra during follow-up. Both groups exhibited significant improvements in VAS score, ODI, anterior vertebral height, and Cobb angle of the fractured vertebra after operation compared to baseline ( P<0.05). There were also significant differences between the two time points after operation ( P<0.05). However, there was no significant difference in the above indicators between the two groups ( P>0.05). CONCLUSION For osteoporotic vertebral upper 1/3 compression fractures treated with unilateral percutaneous curved vertebroplasty, both oblique and parallel puncture methods of the flexible bone cement delivery device can effectively relieve pain, but the former is more conducive to reducing the incidence of secondary puncture.

BACKGROUND: Metabolic-associated fatty liver disease (MAFLD) is the predominant form of chronic liver disease worldwide. This study was designed to investigate the proportion and characteristics of MAFLD within the general Chinese population and to identify the contributory risk factors for liver fibrosis among MAFLD individuals. METHODS: The participants were recruited from a cohort undergoing routine health evaluations at the Third Hospital of Hebei Medical University between May 2019 and March 2023. The diagnosis of MAFLD was based on the established clinical practice guidelines. The fibrosis-4 index score (FIB-4) was employed to evaluate hepatic fibrosis, with a FIB-4 score of ≥1.3 indicating significant fibrosis. Binary logistic regression analyses were used to determine risk factors associated with significant hepatic fibrosis in MAFLD. RESULTS: A total of 22,970 participants who underwent comprehensive medical examinations were included in the analysis. The overall proportion of MAFLD was 28.77% (6608/22,970), with 16.87% (1115/6608) of these patients showing significant fibrosis as assessed using FIB-4. Independent risk factors for significant liver fibrosis in MAFLD patients were male (odds ratio [OR] = 0.676, 95% confidence interval [CI]: 0.558-0.821), hepatitis B surface antigen (HBsAg) positivity (OR = 2.611, 95% CI: 1.557-4.379), body mass index ≥23.00 kg/m 2 (OR = 0.632, 95% CI: 0.470-0.851), blood pressure ≥130/85 mmHg (OR = 1.885, 95% CI: 1.564-2.272), and plasma glucose ≥5.6 mmol/L (OR = 1.815, 95% CI: 1.507-2.186) (all P <0.001). CONCLUSIONS The proportion of MAFLD in an urban Chinese population is 28.77%. About 16.87% of MAFLD patients presented with significant liver fibrosis. Independent risk factors for significant liver fibrosis in MAFLD patients should be noticed.

According to the principle and current domestic and international construction processes of core outcome set(COS) and the characteristics of post-stroke aphasia, this study built COS with evidence-based support for traditional Chinese medicine(TCM) treatment of post-stroke aphasia. Firstly, a comprehensive review was conducted on the articles about the TCM treatment of post-stroke aphasia that were published in the four major Chinese databases, three major English databases, and three clinical registration centers over the past five years. The articles were analyzed and summarized, on the basis of which the main part of the COS for clinical research on the TCM treatment of post-stroke aphasia was formed. Secondly, clinical doctors and related nursing personnel were interviewed, and important outcome indicators in the clinical diagnosis and treatment process were supplemented to form a pool of core outcome indicators. Two rounds of Delphi surveys were carried out to score the importance of the core outcome indicators in the pool. Finally, a consensus meeting of experts was held to establish the COS for clinical research on the TCM treatment of post-stroke aphasia. The final COS included a total of 268 studies [236 randomized controlled trials(RCTs), 21 Meta-analysis, and 11 clinical registration protocols] and 20 open questionnaire survey results. After two rounds of Delphi surveys, a total of 14 outcome indicators and their corresponding measurement tools were included in the expert consensus meeting. The final expert consensus meeting determined the COS for post-stroke aphasia, which included 9 indicator domains and 12 outcome indicators.

Objective:To compare the safety, number of lymph nodes removed, rate of lymph node metastasis, and prognosis between proximal gastrectomy (PG) and total gastrectomy (TG) in patients with Siewert types II and III adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, clinical data of patients diagnosed with adenocarcinoma of the esophagogastric junction at Changzhi People's Hospital, affiliated with Changzhi Medical College, between December 2019 and November 2022, were collected. Patients who had received neoadjuvant therapy, had multiple malignant lesions in the stomach, had concomitant malignancies in other organs, had incomplete clinical data, or had been lost to follow-up were excluded. The study cohort comprised 308 patients, 99 in the PG group and 209 in the TG group. To reduce confounding bias, propensity score matching was performed, matching patients for age, sex, body mass index, tumor diameter, and pathological stage in a 1:1 ratio, resulting in 73 patients in each group. The primary outcomes assessed were operative details, number of lymph nodes dissected, rate of lymph node metastasis, postoperative complications, duration of hospital stay, and follow-up and survival outcomes.Results:The PG group had a significantly shorter median operative time than did the TG group (250 vs. 280 minutes, Z = -4.970, P<0.001), with fewer cases of intraoperative blood loss >100 mL (30.1%[22/73] vs. 46.6%[34/73], χ2=4.171, P=0.041), and a smaller number of lymph nodes removed (median 33 vs. 46, Z =-4.774, P<0.001); all of these differences are statistically significant (all P<0.05). Differences between the two groups in postoperative hospital stay and postoperative complications were not statistically significant (both P>0.05). Furthermore, no statistically significant differences were found between the PG and TG groups in the number of lymph nodes dissected or the lymph node metastasis rates at stations No. 1, No. 2, No. 3, No. 4sa, No. 4sb, and No. 7 (all P> 0.05). Among the 209 patients in the TG group, analysis of risk factors for metastasis to distal perigastric lymph nodes (No.4d, No.5, and No.6) showed that patients with tumor diameters ≤4 cm and T1–T3 stage disease had significantly lower rates of metastasis to these lymph nodes than did patients with tumor diameters >4 cm and/or T4 stage disease (0/78 vs. 12/131 [9.2%]); these differences are statistically significant ( P=0.014). The median duration of follow-up for the entire cohort was 26 months. The 3-year overall survival rates for the PG and TG groups were 62.5% and 63.3%, respectively; this difference is not statistically significant (χ 2=0.330, P = 0.565). Multivariate analysis showed that older age ( P = 0.035) and advanced pathological stage ( P = 0.018) were significant independent risk factors that affected overall survival in patients with Siewert type II and III adenocarcinoma of the esophagogastric junction. Conclusions:PG is safe and feasible for patients with Siewert types II and III adenocarcinoma of the esophagogastric junction. The number of lymph nodes dissected and metastasis status were similar in the TG and PG groups.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.
