ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

Objective To explore the feasibility of endovascular intervention technology for constructing canine models of hepatic vein(HV)obstruction type Budd-Chiari syndrome(BCS).Methods HV obstruction type BCS models were established through double approaches including external jugular vein and percutaneous transhepatic vein puncture,blocking the main HV with double balloon and injecting anhydrous ethanol using 10 Beagle dogs.Laboratory indexes before and after modeling were compared.Liver ultrasound was performed 2,4 and 8 weeks after modeling,respectively,while intravascular ultrasound(IVUS)and digital subtracting angiography(DSA)were performed after the last time ultrasound to observe the obstruction degree,lumen and blood flow of left hepatic vein(LHV).The stenosis rate of LHV was evaluated based on DSA findings,and successful establishment of HV obstruction type BCS canine model was regarded as stenosis rate＞30%and incomplete occlusion of LHV,then the success rate of modeling was recorded.Results No significant difference of laboratory indexes was found before and after modeling(all P＞0.05).Ultrasound,IVUS and DSA showed that after modeling,different degrees of LHV stenosis complicated with intrahepatic collateral circulation were found in 9 dogs,while complete occlusion of LHV was noticed in 1 dog.The success rate of modeling was 90.00%(9/10).Pathological results showed the target HV lumen narrow with thickened endovascular wall,and the latter mainly composed of fibroblast and collagen fiber proliferation.Conclusion Endovascular intervention technology was feasible for constructing canine models of HV obstruction type BCS.

Objective:To investigate the short-term pulmonary function outcomes in children with congenital diaphragmatic hernia (CDH) following surgery and analyze the influencing factors of poor outcomes.Methods:This study retrospectively enrolled 81 children who had undergone surgery for CDH and were discharged after recovery at the Department of Neonatal Surgery, Children's Hospital of Capital Institute of Pediatrics from January 2020 to June 2023. All children had pulmonary function tests before discharge, 6 months to 2 year after discharge. Changes in the pulmonary function parameters at different time points were compared. Based on the results of the final pulmonary function test after discharge, these patients were categorized into a favorable outcome group (32 cases) with normal pulmonary function and an unfavorable outcome group (49 cases) with pulmonary dysfunction. Clinical data of the two groups were compared using two independent samples t-test, rank-sum test, Chi-square test, or Fisher's exact test. Logistic regression analysis was used to explore the factors influencing pulmonary function outcomes. Results:A total of 81 cured and discharged CDH children were included in this study, comprising 34 males (42.0%) and 47 females (58.0%). The first two pulmonary function tests were performed at a mean postnatal age of (30.1±14.1) d (14-75 d) and (8.3±1.3) months (4 months and 14 d to 12 months), respectively. Pre-discharge pulmonary function tests revealed that 13 cases (16.0%) had nearly normal pulmonary function, while 68 cases (84.0%) showed pulmonary function abnormalities with seven cases of restrictive ventilatory dysfunction, 56 cases of obstructive ventilatory dysfunction, and five cases of mixed ventilatory dysfunction. In the children with abnormal pulmonary function before discharge, their second pulmonary function tests showed that some parameters including tidal volume [(7.49±1.35) ml/kg vs. (8.02±2.21) ml/kg], the ratio of time to peak tidal expiratory flow and expiratory time [(23.21±4.95)% vs. (26.50±5.48)%], the ratio of volume to peak expiratory flow and expiratory volume [(26.41±5.79)% vs. (27.55±5.20)%], respiratory system compliance per kg body weight during single occlusion [(0.93±0.22) ml/(cmH 2O·kg) vs. (0.96±0.25) ml/(cmH 2O·kg), 1 cmH 2O=0.098 kPa], functional residual capacity [(52.18±17.83) ml vs. (126.39±26.73) ml], and respiratory system resistance in single occlusion condition [(0.06±0.02) cmH 2O/(ml·s) vs. (0.05±0.01) cmH 2O/(ml·s)] improved after discharge ( t values were－2.41,－6.14,－7.68,－2.26,－18.94, and 4.87, all P<0.05). Eight children with obstructive ventilatory dysfunction were followed up for two years after surgery, of which three had normal lung function and five still showed mild to moderate obstructive ventilatory dysfunction. Logistic regression analysis indicated that liver herniation, severe pulmonary hypertension (PH), low observed-to-expected lung-to-head ratio (o/e LHR), grade C/D diaphragmatic defect, and prolonged invasive ventilation were risk factors for poor pulmonary outcomes [ OR(95% CI) were 5.655(1.410-22.676), 5.610 (1.589-19.804),4.183 (1.234-14.180) and 1.195(1.074- 1.329), all P<0.05]. Conclusions:Although lung function parameters of CDH patients show certain improvement after surgery, many children still have mild to moderate obstructive ventilatory dysfunction, requiring long-term follow-up. Prenatal and postnatal indicators such as liver herniation, severe PH, and low o/e LHR can predict the pulmonary outcomes of children with CDH.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Objective:To compare the efficacy of closed reduction and internal fixation combined with percutaneous kyphoplasty (PKP) and non-operative treatment for intertrochanteric fracture combined with osteoporotic vertebral compression fracture (OVCF) in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 59 patients with intertrochanteric fracture combined with OVCF admitted to Tianjin Hospital from June 2020 to June 2023, including 16 males and 43 females, aged 66-91 years [(80.2±6.8)years]. The injured vertebral segments included T 10 in 3 patients, T 11 in 9, T 12 in 18, L 1 in 17, L 2 in 8, and L 3 in 4. According to the Genant semi-quantitative classification of vertebral fracture, 42 patients were scaled into grade 1 and 17 into grade 2. Based on the AO classification of intertrochanteric fracture, 33 patients were classified as type A1, 21 type A2, and 5 type A3. All the patients underwent closed reduction and internal fixation for intertrochanteric fractures, among whom 26 patients received PKP after the internal fixation of OVCF (PKP group) and 33 patients received non-surgical treatment after the internal fixation of OVCF (non-surgical group). The healing of the hip incision at 2 weeks after internal fixation and the healing of intertrochanteric fractures at 6 months after surgery were observed in both groups. The visual analogue scale (VAS) for low back pain was compared between the two groups before PKP, immediately after PKP, at 3 months after PKP, and at the last follow-up. The Oswestry disability index (ODI), anterior vertebral height ratio, and Cobb angle of the injured vertebrae were compared between the two groups before PKP, at 3 months after PKP, and at the last follow-up. The Harris hip function score was compared between the two groups at 3 months after internal fixation and at the last follow-up. Cement leakage was observed. The incidence of deep vein thrombosis (DVT) in the lower extremities after internal fixation were compared between the two groups. Results:All the patients were followed up for 10-46 months [(25.5±9.9)months]. The hip incisions of both groups all healed by first intention at 2 weeks after internal fixation, and the intertrochanteric fracture in both groups had bony union at 6 months after surgery. There were no significant differences between the two groups in VAS or ODI before PKP ( P>0.05). Immediately after PKP, at 3 months after PKP, and at the last follow-up, the VAS scores for low back pain were (2.6±0.6)points, (2.4±0.9)points, and (1.5±0.5)points in the PKP group, which were lower than those in the non-surgical group [(8.2±0.8)points, (3.7±1.2)points, and (3.3±0.6)points] ( P<0.01). At 3 months after PKP and at the last follow-up, the ODI values were (21.4±6.9)% and (16.2±6.3)% in the PKP group, which were lower than (38.6±11.6)% and (32.7±12.0)% in the non-surgical group ( P<0.01). The VAS for low back pain and ODI in both groups were gradually improved at each time point after PKP compared with those before PKP ( P<0.05 or 0.01). There were no significant differences in the anterior vertebral height ratio or Cobb angle of the injured vertebrae in the two groups before PKP ( P>0.05). At 3 months after PKP and at the last follow-up, the anterior vertebral height ratio was (79.8±9.6)% and (79.3±9.4)% in the PKP group, which were higher than (73.4±9.3)% and (62.0±10.4)% in the non-surgical group ( P<0.05 or 0.01); the values of the Cobb angle of the injured vertebrae were (12.6±3.6)° and (12.0±3.3)°in the PKP group, which were lower than (15.5±2.6)° and (20.4±4.9)° in the non-surgical group ( P<0.01). There were no significant differences in the anterior vertebral height ratio and Cobb angle of the injured vertebrae in the PKP group before PKP and at each time point after PKP ( P>0.05) while in the non-surgical group, the anterior vertebral height ratio at each time point after PKP was lower than that before PKP and the Cobb angle of the injured vertebrae was increased compared with that before PKP ( P<0.01). At 3 months after internal fixation and at the last follow-up, the Harris hip function scores in the PKP group were (76.4±3.4)points and (87.7±4.5)points, which were higher than (57.0±6.8)points and (76.3±8.9)points in the non-surgical group ( P<0.01). The Harris hip function scores in both groups were improved at the last follow-up, compared with those at 3 months after internal fixation. Five patients had cement leakage in the PKP group, all of which were lateral leakage.There was no occurrence of radiating pain in the lower extremities. The incidence of DVT at 1 month after internal fixation was 19.2% (5/26) in the PKP group, which was lower than 57.6% (19/33) in the non-surgical group ( P<0.01). Conclusion:Compared with non-operative treatment after the closed reduction and internal fixation, PKP after internal fixation can significantly relieve low back pain in the early stage, improve the functional restoration of the vertebral column, maintain vertebral height, prevent kyphosis, promote the recovery of the hip joint function, and reduce the occurrence of DVT in the lower extremities in the treatment of intertrochanteric fracture combined with OVCF.
