ObjectiveTo observe the clinical efficacy of the Yiqi Yangyin Huoxue prescription （YYHP） in the treatment of cathartic colon （CC） and its effects on fecal short-chain fatty acids （SCFAs）， and to explore the correlations among CC severity indicators and between these indicators and patient history. MethodsAccording to the inclusion and exclusion criteria， 98 patients meeting the diagnostic criteria of both traditional Chinese and Western medicine for CC with the syndrome of Qi-Yin deficiency complicated by blood stasis were randomly assigned to an observation group and a control group. The observation group received YYHP granules， while the control group received lactulose. Both medications were administered twice daily， one sachet each time， half an hour after breakfast and dinner， with a treatment course of 8 weeks. The primary constipation symptom score， Patient Assessment of Constipation Quality of Life （PAC-QOL） score， and TCM syndrome score were assessed before and after treatment and at the 8^th week after the end of treatment. The overall clinical effective rate， as well as the efficacy attenuation index and degree， were evaluated. Fecal SCFA levels were measured using gas chromatography-mass spectrometry （GC-MS）. Spearman correlation analysis was performed to explore the correlations among CC severity indicators and between these indicators and patient history. ResultsThe overall clinical effective rate in the observation group （95.83%） was higher than that in the control group （78.72%） （P<0.05）. After treatment， the total scores for primary constipation symptoms， PAC-QOL， and TCM syndromes decreased in both groups （P<0.05）， with more significant reductions in the observation group （P<0.05）. The severity of all primary constipation symptoms was alleviated in both groups （P<0.05）. In terms of "excessive straining and difficult defecation"， "anal heaviness， incomplete evacuation， and bloating sensation"， "abdominal distension"， and "defecation frequency"， the observation group showed better efficacy than the control group （P<0.05）. Scores of the four PAC-QOL dimensions and the scores and severity of primary and secondary TCM symptoms were reduced in both groups （P<0.05）， with more significant reductions in the observation group （P<0.05）. After treatment， acetic acid， propionic acid， butyric acid， and total SCFAs in the observation group increased significantly （P<0.05）. The efficacy attenuation index and degree in the observation group were lower than those in the control group （P<0.05）. No severe adverse reactions occurred in either group， and there was no statistically significant difference in the incidence of adverse reactions between the two groups. Positive correlations of varying degrees were observed among the total scores of primary constipation symptoms， PAC-QOL， and TCM syndromes， as well as between these scores and the history of stimulant laxative use， disease duration， and age. ConclusionYYHP can effectively alleviate the primary constipation symptoms in CC patients， improve quality of life， and ameliorate TCM syndromes， with good safety. It also has the advantage of a lower rebound degree after drug withdrawal， and its mechanism may be related to increasing fecal SCFA levels. Long-term abuse of stimulant laxatives may aggravate the severity of CC and prolong the disease course.

Objective To systematically reconstruct the evolution of schistosomiasis prevalence in China from 1950 to 2024, so as to fill the gap of national data on schistosomiasis prevalence in China before 1986. Methods Schistosomiasis control data were collected from schistosomiasis-endemic areas of China before 1986, which mainly included statistical data on schistosomiasis, compilations of control records, annual work reports, and academic papers. Data pertaining to the prevalence of schistosomiasis from each province (autonomous region, municipality) were collected and summarized annually, and integrated into national annual work reports for schistosomiasis control in China from 1986 to 2024 to build a national schistosomiasis epidemic database covering schistosomiasis patients, cattle with schistosomiasis, and Oncomelania hupensis snails. The provincial-level epidemic data of schistosomiasis were summarized annually from 1986 to 2024 with pivot tables, and then the national epidemic data of schis tosomiasis were summarized. The temporal trends in key epidemic indicators of schistosomiasis were analyzed in China from 1950 to 2024. Results A complete time-series dataset of schistosomiasis was established in China from 1950 to 2024 through systematic reconstruction of multi-source historical documents and materials. A total of 1.97 million newly detected schistosomiasis cases were recorded in China from 1950 to 2024, and the actual number of schistosomiasis patients was all more than 1 million each year from 1955 to 1978. There were only more than 20 000 advanced schistosomiasis patients in China by the end of 2024, and the prevalence of Schistosoma japonicum human infections reduced from 34.6% in 1950 to below 1.0% after 1996. A total of 2.47 million cattle were tested positive for schistosomiasis, and the prevalence of S. japonicum infections reduced from 21.4% in bovines since 1950. The area of emerging O. hupensis snail habitats was concentrated during the period between 1956 and 1958, accounting for 49.8% of total areas, while the area of emerging O. hupensis snail habitats significantly decreased since 1992, indicating a stable distribution pattern of O. hupensis snails. Data validation results showed that the cumulative variation in areas of O. hupensis snail habitats was 1.6%, and the cumulative variation in the number of schistosomiasis cases was 1.4%. Join-point regression analysis revealed four turning points in the prevalence of S. japonicum infections in humans and seven turning points in the prevalence of S. japonicum infections in livestock across China from 1955 to 2024. Conclusions Through the joint efforts of the Communist Party of China and government leadership, interdepartmental collaboration, professional teams, scientific and technological innovation, and public participation, the schistosomiasis epidemic has been effectively controlled in China following active control for more than 70 years. This study builds, for the first time, a complete time-series dataset on schistosomiasis in China, which provides insights into assessment of the effectiveness of schistosomiasis control programmes and refinement of the experience from schistosomiasis control programmes in China.

ObjectiveTo systematically compare the effects of diverse electromagnetic stimulation protocols on hand function and activities of daily living (ADL) in stroke patients using network meta-analysis (NMA), and screen the optimal stimulation strategy for post-stroke hand dysfunction rehabilitation. MethodsNMA was performed in accordance with the PRISMA-NMA statement. Databases of CNKI, Wanfang data, VIP, CBM, PubMed, Web of Science and Embase were searched from database inception to April, 2026 for eligible randomized controlled trials (RCTs) comparing different electromagnetic stimulation protocols for post-stroke hand impairment. The Cochrane Risk of Bias tool and PEDro scale were used to assess methodological quality of included studies, while the GRADE system was adopted to grade evidence quality of primary outcomes of Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI). After literature screening, data extraction and bias evaluation, RevMan 5.4 and Stata 17.0 were used for meta-analysis and NMA. ResultsA total of 22 RCT involving 17 electromagnetic stimulation protocols were finally included. The PEDro scores ranged from six to ten. The top five protocols for improving FMA-UE score were repetitive peripheral magnetic stimulation (rPMS) + repetitive transcranial magnetic stimulation (rTMS), intermittent theta-burst stimulation (iTBS) + rPMS, iTBS + transcranial direct current stimulation (tDCS), transcutaneous electrical acupoint stimulation (TEAS) and contralaterally controlled functional electrical stimulation (CCFES). tDCS was the most effective on MBI, followed by TEAS and iTBS+rPMS. Evidence quality for FMA-UE and MBI was moderate. Funnel plots suggested low risk of publication bias, and consistency tests verified good coherence between direct and indirect comparisons in network models. ConclusionElectromagnetic stimulation significantly facilitates upper limb and hand functional recovery, and improves ADL in stroke patients. The combined central-peripheral magnetic stimulation protocol may be the most effective on motor rehabilitation, whereas tDCS on ADL.

Objective: To evaluate the effect of repeated testing combined with cross-validation using different principles of NAT systems on improving the detection rate of occult HBV infection (OBI) in HBsAg-negative/NDR samples. Methods: A total of 89 NDR samples from the Taiyuan Blood Center between August 2024 and May 2025 were enrolled. All samples were tested for HBsAg by ELISA and subjected to NAT screening using the Roche system (PCR method). For all HBsAgnegative, MPNAT+/IDNAT (NDR) samples, further crossvalidation was performed using repeat IDNAT with the Roche system and the Grifols system (TMAbased) dHBV discriminatory assay; in addition, HBV serological markers were detected, and the results were confirmed by realtime quantitative PCR and nested PCR with sequencing genotyping. The NAT yield/window period ratio model was used to estimate the residual risk of HBV transfusion for the Roche single system in actual use, and the theoretical residual risk was calculated by assuming that the Grifols system was applied to individual screening of all blood donors. Results: The detection rate of HBsAg-negative/NDR was 0.99‰ (89/90 115), consistent with the national average. Among the 89 NDR samples, 4 were confirmed as HBV DNA-positive by nested PCR (viral load 15 - 20 IU/mL), including 3 of genotype C1 and 1 of genotype B2. Serological analysis showed that the anti-HBc positivity rate in NDR samples was 24.7% (22/89); all 4 OBI samples were antiHBcpositive (18.2%) and none were antiHB-spositive. In the single-NAT system, the residual risk for first-time donors (RR_FD) was 48.98/10 person-years for the Roche system and 21.01/10 person-years for the Grifols system, both higher than the corresponding residual risk for repeat donors (RR_RD: 15.23/10 and 9.80/10 person-years, respectively), but the differences showed no statistical significance (P>0.05). Conclusion: Implementing repeated testing combined with cross-validation using different principles of NAT systems can effectively increase the detection rate of low-viral-load OBI and reduce the risk of missed detection.

Background: In acute and chronic renal inflammatory diseases, the activation of inflammatory cells is involved in the defect of erythropoietin (EPO) production. Ras guanine nucleotide-releasing protein-4 (RasGRP4) promotes renal inflammatory injury in type 2 diabetes mellitus (T2DM). Our study aimed to investigate the role and mechanism of RasGRP4 in the production of renal EPO in diabetes. Methods: The degree of tissue injury was observed by pathological staining. Inflammatory cell infiltration was analyzed by immunohistochemical staining. Serum EPO levels were detected by enzyme-linked immunosorbent assay, and EPO production and renal interstitial fibrosis were analyzed by immunofluorescence. Quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression of key inflammatory factors and the activation of signaling pathways. In vitro, the interaction between peripheral blood mononuclear cells (PBMCs) and C3H10T1/2 cells was investigated via cell coculture experiments. Results: RasGRP4 decreased the expression of hypoxia-inducible factor 2-alpha (HIF2A) via the ubiquitination–proteasome degradation pathway and promoted myofibroblastic transformation by activating critical inflammatory pathways, consequently reducing the production of EPO in T2DM mice. Conclusion RasGRP4 participates in the production of renal EPO in diabetic mice by affecting the secretion of proinflammatory cytokines in PBMCs, degrading HIF2A, and promoting the myofibroblastic transformation of C3H10T1/2 cells.

Objective:To investigate the effects of CO2 intracavitary laser combined with pelvic floor magnetic stimulation on surface electromyography(sEMG)values and pelvic floor three-dimensional ultrasound parameters in female patients with stress urinary incontinence(SUI).Methods:A prospective study was conducted on 92 female SUI patients treated at the outpatient department of Meizhou People's Hospital from October 2021 to July 2023.The patients were randomly divided into an observation group and a control group(n=46 each)using a random number table.Both groups received home-based pelvic floor muscle training.The control group additionally received pelvic floor magnetic stimulation,while the observation group was treated with CO2 intracavitary laser combined with pelvic floor magnetic stimulation.The urinary leakage status,treatment efficacy,pelvic floor muscle sEMG,pelvic floor three-dimensional ultrasound parameters,quality of life,and sexual quality of life were compared between the two groups.Assessments included the International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF),the Incontinence Impact Questionnaire-Short Form(IIQ-7),and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire(PISQ-12).Results:1-hour leakage volume:0 g(observation group)vs.3 g(control group),24-hour leakage episodes:0 times(observation group)vs.0 times(control group),the observed differences were statistically significant(Z=-2.866,-2.355,P<0.05).Total effective rate:95.65%(observation)vs.58.70%(control),the observed differences were statistically significant(x2=4.083,P<0.05).Pelvic floor muscle sEMG(after treatment):Maximal fast contraction:(40.78±3.28)μV(observation)vs.(35.17±5.10)μV(control),Mean tonic contraction:(31.56±4.20)μV(observation)vs.(25.87±3.82)μV(control),Mean endurance contraction:(29.34±2.58)μV(observation)vs.(25.37±2.67)μV(control),all differences between the two groups were statistically significant(t=2.736,19.919,3.025,15.426,P<0.05).After treatment,both groups showed reductions in bladder neck descent(BND)during Valsalva maneuver,bladder-symphysis distance(BSD),urethral rotation angle(URA),and posterior vesicourethral angle(RVA).However,the observation group demonstrated significantly greater reductions compared to the control group(post-treatment data:observation group(24.30±3.21)mm,(2.34±0.23)mm,(56.40±5.87)°,(89.54±9.21)°;control group(26.21±3.48)mm,(3.57±0.35)mm,(60.29±6.45)°,(126.71±13.50)°.These differences were statistically significant(t=2.736,19.919,3.025,15.426,P<0.05).Similarly,both groups exhibited decreased scores on the ICIQ-SF and IIQ-7 scales,along with increased scores on the PISQ-12.Again,the observation group showed superior improvement,with statistically significant differences(t=11.478,13.168,6.631,P<0.05).Conclusion:On the basis of pelvic floor muscle training,CO2 intracavitary laser therapy combined with pelvic floor magnetic stimulation can effectively alleviate urinary incontinence symptoms in patients with female stress urinary incontinence(FSUI),enhance therapeutic efficacy,improve pelvic floor muscle strength and the stability of pelvic support structures,and promote quality of life and sexual function.

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.

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.
