Objective: To evaluate the methodological quality and reporting quality of clinical practice guidelines or expert consensus on blood transfusion and blood use (BTBU) in China (hereinafter referred to as "guidelines/consensus"), providing reference for the development and updating of future BTBU guidelines/consensus. Methods: A systematic search was conducted in Chinese databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Data-base, relevant guideline release platforms, and professional association websites. BTBU-related guidelines/consensus published between January 2006 and December 2025 were included. According to the inclusion and exclusion criteria, after completing literature screening and data extraction, three evaluators independently assessed the quality of the included literature using the Scientificity, Transparency, and Applicability of Guidelines Rating Tool (STAR), the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), and the International Practice Guideline Reporting Standards (RIGHT). Results: A total of 29 documents were included, including 5 guidelines, 22 consensus statements, and 2 protocols. The results of the STAR assessment showed that the total score was (21.7±8.8)%. The domain score ratios for registration, research protocol, funding, working group, conflict of interest, clinical question, evidence, consensus method, recommendation, accessibility and other domains were (2.2±12.1)%, 0, (36.7±25.1)%, (18.3±7.6)%, (19.2±15.3)%, (16.6±23.1)%, (15.1±6.3)%, (9.6±21.2)%, (54.3±18.4)%, (31.7±10.4)% and (10.3±31.0)%, respectively. For the AGREE Ⅱ assessment, the methodological quality of 26 articles was rated Grade B and 3 articles Grade C. The results of the RIGHT assessment indicated that the overall reporting rate of all guidelines/consensuses was (65.3±4.0)%. Conclusion: The methodological and reporting quality of current expert guidelines/consensus on BTBU in China still need improvement, and guidelines and consensus should be strictly formulated and standardized according to the standards of STAR, AGREE II and RIGHT.

OBJECTIVE To investigate the effect and mechanism of bumetanide on lung injury in chronic obstructive pulmonary disease(COPD)model rats.METHODS COPD rat model was induced by lipopolysaccharide,and they were randomly divided into model group(COPD group),bumetanide low-dose and high-dose groups(Bumetanide-L group,Bumetanide-H group),bumetanide high-dose+Yes-associated protein/transcriptional coactivator containing PDZ-binding motif(YAP/TAZ)signaling pathway activator group(Bumetanide-H+PY-60 group),with 12 rats in each group.Another 12 normal rats were selected as normal control group(Control group).Thirty minutes before modeling,bumetanide/normal saline was inhaled or/and PY-60/normal saline was injected into the tail vein.On the next day after the completion of modeling and drug administration,the pulmonary function index of the rats in each group was measured[forced expiratory volume in 0.3 seconds(FEV0.3),forced vital capacity(FVC),peak expiratory flow(PEF),FEV0.3/FVC].The levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and IL-1β in bronchoalveolar lavage fluid(BALF)were determined;the pathological morphology of lung tissue and degree of pulmonary fibrosis were observed.The expression levels of transforming growth factor-β(TGF-β),α-smooth muscle actin(α-SMA)and TAZ protein as well as the phosphorylation of YAP protein in lung tissues were detected.RESULTS Compared with COPD group,the pathological injury of lung tissue in Bumetanide-L and Bumetanide-H groups was alleviated;the exfoliation of lung epithelial cells,tube wall thickening and the degree of pulmonary fibrosis were alleviated;inflammatory cell infiltration was reduced,and blue collagen deposition was reduced;FEV0.3,FVC,FEV0.3/FVC and PEF were significantly increased,while the lung injury score,levels of TNF-α,IL-6,IL-1β,expression levels of TGF-β,α-SMA and TAZ protein and the phosphorylation of YAP protein were significantly decreased(P＜0.05).PY-60 could significantly reverse the improvement effects of bumetanide on above indexes(P＜0.05).CONCLUSIONS Bumetanide can alleviate lung injury,inflammatory response and pulmonary fibrosis in COPD rats,and its mechanism is related to inhibiting YAP/TAZ signaling pathway.

Objective:To understand the real experience of caregivers of children with craniopharyngioma-associated hypothalamic obesity (CP-HO) based on the chronic disease trajectory model, so as to provide a reference for formulating corresponding disease management plans.Methods:From May 2023 to July 2023, semi-structured interviews were conducted with 17 caregivers of children with CP-HO who were admitted to the Department of Neurosurgery, Nanfang Hospital, Southern Medical University through purposive sampling. The interview data were analyzed by Colaizzi 7-step analysis method.Results:The 17 caregivers of children with CP-HO were 24 to 46 years old, including 3 males and 14 females. A total of 3 themes were extracted. Prodromal phase of weight: lack of disease cognition and weakening of self-concept; during the period of weight increase, the demand burden became prominent and the life pattern changed; weight stability: pressure, hope, and insight into the value of life.Conclusions:For promoting a good disease response of caregivers and improving the weight management effect of children and the quality of family life, medical staff should pay attention to and understand the disease care experience of children with CP-HO, and provide comprehensive and systematic solution strategies.

To establish a fluorescence-labeled Corynebacterium pseudotuberculosis(Cp),the super-folded green fluorescent protein gene(sfGFP)fused to the red fluorescent protein gene(mCher-ry)was cloned into pXMJ19 and expressed in Cp.The fluorescent signals of recombinant Cp cul-tured under different pH values,and the visualized detection of bacteria in the macrophages J774A.1 or mice infected with recombinant Cp were evaluated.The results showed that a double fluores-cence labeled XH02-pXMJ19-sfGFPmCherry(XH02-sfGFPmCherry)was successfully construc-ted by electrotransformation of Cp with pXMJ19-sfGFPmCherry,which containing sfGFP fused to mCherry.The colony morphology of XH02-sfGFPmCherry on fresh blood agar plates was pink.The XH02-sfGFP mCherry showed green and red fluorescence when observed under the fluo-rescence microscope.Compared with cultivation at pH7.0,XH02-sfGFPmCherry showed a signifi-cant decrease in green fluorescence intensity(fluorescence intensity/D600)at pH5.0,but signifi-cantly increased in red fluorescence intensity at pH5.0.Green and red fluorescences of Cp were ob-served in the XH02-sfGFPmCherry-infected J774A.1 in vitro or in the liver and kidney of XH02-sfGFPmCherry-infected mice in vivo,and with good overlap of two kinds of fluorescences.This study demonstrates that the constructed dual fluorescent labeled Cp can efficiently express both red and green fluorescent proteins,and express the dominant fluorescent signals under different pH value conditions,which can be used for Cp monitoring in vitro infection of macrophages and in vivo infection of mice by this pathogen,and providing potential tool for the localization and tracing research of Cp infection.

ObjectiveTo investigate the characteristics of gender difference and the trend of the mortality rate of senile dementia in registered population in Shanghai from year 2002 to 2018， and to provide the basis for formulating relative intervention measures before and after senile dementia from an public-health view. MethodsBased on the collected data of death registration， focused on the senile dementia disease codes F03，G30.0，G30.1，G30.8，G30.9 according to The International Classification of Diseases 10th revision （ICD-10）. We analyzed the characteristics of gender difference in the mortality rate of senile dementia in registered population in Shanghai from year 2002 to 2018. According to ASR， we calculated the standardized mortality rate of senile dementia， and used the chi-square test to compare the difference between the gender mortality rates. The trend and the turning point of the mortality rate of senile dementia were determined by linear regression analysis by Join-point. ResultsThe crude mortality rate of senile dementia in the registered population in Shanghai from year 2002 to 2018 was 5.46/10⁵， 3.50/10⁵ in males and 7.43/10⁵ in females. The standardized mortality rate of senile dementia was 2.61/10⁵， 1.67/10⁵ in males and 3.56/10⁵ in females. The trend of the standardized mortality rate of senile dementia in 17 years decreased ［APC=-5.5（-6.5，-4.5）%，P<0.01］. The trend of the standardized mortality rate of senile dementia decreased in both males ［APC=-4.9（-6.2，-3.6）%，P<0.01］ and females ［APC=-5.9（-6.9，-4.9）%，P<0.01］. The trend of the gender difference decreased ［APC=-6.8（-8.2，-5.3）%，P<0.01］. The mortality rate of senile dementia was higher in females than in males ［（χ²=33.63，P<0.01）］. ConclusionThe mortality rate of senile dementia in females is higher than in males in Shanghai， though the trend of the gender difference decreased. This gender difference is worth of attention.

ObjectiveTo analyze the dynamic response relationship between urban development and mortality rate in Shanghai， and to predict the trend of mortality rate changes. MethodsBy analyzing the total mortality rate （TMR）， gross domestic product （GDP） and socio-demographic index （SDI） in Shanghai from 1978 to 2017， a vector autoregressive （VAR） model was constructed to evaluate the impact of urban development on the mortality rate. ResultsThe fitted R2 of the VAR model was 0.92. The short-term effect of GDP on the improvement of death level was negative， while the long-term effect was positive， and the SDI was negative regardless of the short-term and long-term effects. By the tenth year， GDP and SDI contributed 10.61% and 27.25% to TMR changes， respectively. The model predicted that the mortality rate in Shanghai would be 9.17 per thousand by 2030. ConclusionLong-term economic growth can effectively promote a decline in population mortality. However， as the economy develops vigorously， the adverse effects of declining birth rates and population aging on population health during the era of high-level population development should not be ignored.

Objective:To investigate the clinical effect of minimally invasive catheterization based on computer 3D-Slicer software system in the treatment of hypertensive intracerebral hemorrhage (HICH).Methods:Three hundred and fifty patients with HICH treated in People′s Hospital of Lanling County in Shandongfrom June 2019 to June 2020 were selected as the research object. According to the operation method, they were divided into 3D-Slicer group (175 cases) and CT group (175 cases). They were treated with 3D-Slicer software-assisted minimally invasive catheterization and minimally invasive soft-channel drainage under CT localization, respectively. The general conditions of the surgery, hematoma clearance rate and laboratory indexes, oxidative stress index and prognosis were compared between the two groups.Results:The intraoperative blood loss, the hospitalizationtimein the 3D-Slicer group were lower than those in the CT group: (81.42 ± 12.33) ml vs. (101.54 ± 11.71) ml, (15.67 ± 3.71) d vs. (17.22 ± 3.52) d; the success rate of one-time successful puncture to preset position in the 3D-Slicer group was higher than that in the CT group: 100.00%(175/175) vs. 81.14%(142/175), there were statistical differences ( χ 2 = 34.26, P<0.05). The hematoma clearance rate after the surgery for 1, 3 and 7d in the 3D-Slicer group were higher than those in the CT group:(87.93 ± 8.54)% vs. (66.43 ± 7.99)%, (92.48 ± 10.31)% vs. (89.52 ± 11.74)%, (96.37 ± 10.22)% vs. (94.30 ± 9.25)%, there were statistical differences( P<0.05). After the surgery for 7 d, the levels of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) in the 3D-Slicer group were higher than those in the CT group: (121.36 ± 10.59)U/L vs. (109.14 ± 9.05) U/L, (92.80 ± 8.63) μg/L vs. (81.45 ± 9.11) μg/L, (24.64 ± 5.43) U/L vs. (20.84 ± 3.47) U/L; while the level of malondialdehyde (MDA) was lower than that in the CT group: (4.42 ± 0.57)μmol/L vs. (5.19 ± 0.51) μmol/L, there were statistical differences ( P<0.05). After the surgery for 3 months, the rate of favorable prognosis in the 3D-Slicer group was higher than that in the CT group 73.71%(129/175) vs. 62.29%(199/175), there was statistical difference ( χ2 = 5.25, P<0.05). Conclusions:Minimally invasive catheterization based on 3D-Slicer software system in the treatment of HICH can not only improve the clinical efficacy, but also shorten the hospitalization time, reduce intraoperative blood loss, and improve the prognosis.

Objective:To explore the pregnancy outcomes of frozen-thawed embryo transfer (FET) after antibiotic treatment in patients with recurrent implantation failure (RIF) and chronic endometritis (CE).Methods:A retrospective cohort study was conducted to analyze 496 women with RIF undergoing hysteroscopy and endometrial biopsy before the next FET in Reproductive Medicine Center of Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2018 to December 2021. According to the pathological results of endometrial biopsy and subsequent treatment, the patients were divided into cured CE group (strong positive CD138 was converted to negative after antibiotic treatment, n=103), suspected CE group (weak positive CD138, n=76), non-CE group (negative CD138, n=230) and control group (hysteroscopy and diagnostic only, no CE-related histopathological screening, n=85). The pregnancy outcomes after FET were compared among the four groups. Results:The prevalence of CE in the patients with RIF was 25.5% (105/411), and the sensitivity of hysteroscopy for the diagnosis of CE was 55.2% and the specificity was 83.0%. The conversion rate of patients with CE was 86.7% (91/105) after 1 cycle of antibiotic treatment and 98.1% (103/105) after 2 cycles of treatment. After removing the confounding factors of age, ovarian reserve function, number of previous transfer cycles, number and type of embryos transferred in FET cycle, and number of high-quality embryos, multivariate regression analysis showed that the clinical pregnancy rate of the cured CE group improved significantly after antibiotic treatment ( OR=1.841, 95% CI: 1.123-3.020, P=0.029). Conclusion:Patients with RIF should be screened for CE, and if CE is diagnosed, pharmacological treatment is recommended prior to embryo transfer, which is beneficial to improve pregnancy outcomes in FET cycles.
