ObjectiveTo compare the mosquito capture efficacy of the BG-trap method and the light trap method, and to explore the precisely applicable scenarios for the two monitoring approaches. MethodsFrom May to October 2024, one BG-trap and one light trap were placed at eight monitoring sites, with a distance of over 10 meters between the two traps at each site. Surveillance was performed twice monthly to compare the two surveillance methods in terms of mosquito species composition, the proportional distribution of female mosquitoes across different habitats, and seasonal fluctuations in mosquito density. ResultsThere were statistically significant differences in mosquito species composition (χ²=60.61, P<0.001) and female mosquito species composition (χ²=37.12, P<0.001) between the BG-trap method and the light trap method, with the BG-trap method capturing a higher proportion of Aedes albopictus than the light trap method. The average density of mosquitoes monitored by the BG-trap method [13.36 mosquitoes·(trap·night)^-1] was higher than that monitored by the light trap method[4.70 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.70, P<0.001) for the mosquito density between the two methods, and there was a significant positive correlation (r=0.909, P<0.001) for the mosquito density indices between the two methods. The average density of female mosquitoes monitored by the BG-trap method [8.18 mosquitoes·(trap·night)^-1] was higher than that monitored by light trap method [3.36 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.00, P<0.001) for the female mosquito density between the two methods, and there was a significant positive correlation (r=0.929, P<0.001) for the female mosquito density indices between the two methods. In the four different habitats, the constituent ratio of mosquitoes and female mosquitoes monitored by the BG-trap method in descending order were urban residential area (43.80% and 40.25%), rural farm households (35.55% and 38.60%), hospital (12.70% and 12.87%), and park (7.95% and 8.28%), while the constituent ratio of mosquitoes and female mosquitoes monitored by the light trap method in descending order were rural farm households (34.37% and 43.34%), hospital (33.26% and 30.03%), park (17.96% and 15.17%), and urban residential area (14.41% and 11.46%). In different habitats, there were statistically significant differences for mosquito composition ratios (χ²=189.64, P<0.001) and female mosquito composition ratios (χ²=109.15, P<0.001) between the two monitoring methods. ConclusionThe BG-trap method offers advantages such as simple operation, compact equipment, and high efficiency, with a higher trapping rate for Aedes albopictus compared to the light trap method. In routine monitoring, the BG-trap method can serve as a supplement to the light trap method, while for emergency monitoring of Aedes albopictus in dengue fever outbreak areas and mosquito collection efforts, the BG-trap method is more effective than the light trap method.

OBJECTIVE To investigate the current status of informatization tools applied to antimicrobial stewardship in county hospitals in China， and to provide a reference for promoting the informatization development of antimicrobial stewardship in county hospitals.METHODS From August to September 2025， an online questionnaire survey was conducted among 1 007 county hospitals across 31 provinces（autonomous regions， and municipalities） in China. The survey focused on the application of four types of informatization tools：the real-time monitoring system for antimicrobial use， the pre-prescription review system， the irrational use warning system， and the electronic prescription evaluation system（hereinafter referred to as the “monitoring system”“review system”“warning system”“evaluation system”，respectively）. Correlation analysis and binary Logistic regression analysis were employed to explore the influencing factors.RESULTS Of the county hospitals， 80.83% were equipped with at least one type of informatization tool for antimicrobial stewardship， while 19.17% had no relevant tool. Only 18.87% of the hospitals were equipped with all four types of tools. The monitoring system exhibited the highest equipped rate （70.80%）， whereas the warning system was equipped in only 33.96% of the hospitals. Four types of tools are evenly and adequately deployed in the eastern region， the central and western regions have far lower deployment rates of intervention tools including review system and warning system， accompanied by prominent intra-provincial gaps. The total number of the health technicians， hospital grade， and prescription review rate of outpatient antibacterial drug were significantly and positively correlated with the deployment rates of the four informatization tools （ P ＜0.05）. The results of the Logistic regression model fitting indicated that the model of the review system was rated “excellent” [area under the receiver operating characteristic curve （AUC）＝0.81]， and the model of the warning system was rated “further improvement” （AUC＝0.67）. The total number of health technicians was significantly positively correlated with the deployment rates of all four types of informatization tools （all P ＜0.05）.CONCLUSIONS The informatization of antimicrobial stewardship in county hospitals in China remains in the initial stage of transitioning from “passive statistics” to “active prevention and control”， with challenges such as structural imbalance and regional disparities. In the future， differentiated support strategies should be implemented， the allocation of resources should be optimized， to enhance the level of refined antimicrobial stewardship.

ObjectiveTo investigate the expression of family with sequence similarity 162 member A （Fam162a）， a mitochondrial inner membrane protein， in the fibrosis of cardiac fibroblasts and its regulatory role in modulating the fibrotic phenotype of cardiac fibroblasts. MethodsFam162a protein expression was detected in myocardial samples from patients with heart failure （HF） and mice with transverse aortic constriction （TAC）-induced myocardial remodeling. Primary neonatal mouse cardiac fibroblasts （mCFs） were isolated and cultured， and a cell model of angiotensin Ⅱ （Ang Ⅱ）-induced myocardial fibrosis was established to determine Fam162a protein expression. Recombinant adenovirus was used to mediate Fam162a overexpression， while small interfering RNA （si-RNA） was employed for Fam162a knockdown. Western blot was performed to detect the expression of fibrosis-related proteins， including COL1A1， COL3A1， and α-SMA. EdU staining assay was used to evaluate cell proliferation capacity， and scratch assay combined with Transwell assay was conducted to assess cell migration ability. Immunofluorescence assay was applied to measure mitochondrial membrane potential for reflecting mitochondrial dysfunction； reactive oxygen species （ROS） detection was performed to evaluate cellular oxidative stress status； MitoSox assay was used to reflect the degree of mitochondrial oxidative damage； and ATP detection was conducted to assess the overall cellular energy metabolism. ResultsFam162a expression was significantly downregulated in the myocardium of HF patients and TAC mice， and Ang Ⅱ-treated mCFs， accompanied by increased expression of COL1A1， COL3A1， and α-SMA （all P＜0.05）. Adenovirus-mediated overexpression of Fam162a significantly inhibited Ang Ⅱ-induced upregulation of fibrosis-related genes， as well as cell proliferation and migration. Accordingly， silencing Fam162a aggravated the fibrotic phenotypes of mCFs treated with Ang II. Further studies revealed that the inhibitory effect of Fam162a overexpression on Ang Ⅱ-induced fibrotic phenotype was suppressed following the addition of rotenone （a mitochondrial oxidative respiratory chain inhibitor）， which was accompanied by mitochondrial membrane potential depolarization， excessive ROS production， and insufficient ATP generation. ConclusionFam162a exerts its inhibitory effect on the fibrotic phenotype of cardiac fibroblasts by maintaining mitochondrial membrane potential， promoting ATP production， reducing reactive oxygen species （ROS） generation， and suppressing Smad3 signaling activation.

Objective To investigate the clinical characteristics and outcomes of Coronavirus Dis-ease 2019 in immunocompromised hosts.Methods A retrospective analysis was conducted on the clinical data of 230 hospitalized patients diagnosed with Coronavirus Disease 2019 at Nanjing Yimin Hospital from December 2022 to November 2023.The patients were divided into three groups based on their immune status:immunocompromised group(n=59),relatively immunocompromised group(n=129),and immunocompetent group(n=42).The clinical characteristics(such as clinical manifesta-tions,imaging features,and laboratory examinations)and outcomes(such as length of hospital stay and in-hospital mortality)were compared among three groups.Results Compared with there latively immunocompromised and immunocompetent groups,the immunocompromised group showed no obvious specific clinical manifestations.However,the proportions of patients with symptoms such as cough and expectoration were lower,and the occurrences of symptoms such as myalgia and fatigue were less fre-quent in the immunocompromised group(P＜0.05).The chest CT findings in the immunocompro-mised group also lacked specific changes,mainly presenting as subpleural ground-glass opacities and consolidations with multilobar distribution,but fibrotic changes were more common(P＜0.05).The proportion of patients with decreased absolute lymphocyte counts in the immunocompromised group was higher than that in the immunocompetent group,and the proportion of patients with elevated procalcitonin levels was higher than that in the other two groups(P＜0.05).The proportion of severe case sand the length of hospital stay in the immunocompromised group were higher and longer than those in the relatively immunocompromised and immunocompetent groups(P＜0.05).The in-hospital mortality rates in the immunocompromised,relatively immunocompromised,and immunocompetent groups were 10.17％,6.98％,and 2.38％,respectively,with no statistically significant difference(P＞0.05).Conclusion After Coronavirus Disease 2019,immunocompromised hosts do not show obvi-ous clinical and imaging features.However,they have a prolonged length of hospital stay,a signifi-cantly higher proportion of severe cases,and a tendency towards increased in-hospital mortality,which should be given high clinical attention.

Objective:To explore the impacts of different frequencies of orthogonal image-guided verification on set-up error correction and the reference values of planning target volume (PTV) margins in postoperative radiotherapy for breast cancer, in order to provide recommendations of the verification frequency in clinical practice.Methods:A total of 80 breast cancer patients who received postoperative intensity-modulated radiotherapy for breast cancer at the Affiliated Union Hospital of Fujian Medical University from January 2021 to January 2022 were enrolled. Orthogonal image-guided verification was conducted before each radiation treatment to determine initial and residual set-up errors. The error data were statistically analyzed by categorizing patients into groups A, B, C, D, E, and F, based on assumed verification frequencies (daily, every 2, 3, 4, and 5 d, and no correction). The magnitude, distribution, and differences of set-up errors of various groups were analyzed, and the PTV margins were calculated using a reference formula.Results:The collected initial set-up errors of the 80 patients were (3.49±3.43), (2.87±2.88), and (2.75±2.35) mm, in x, y, and z directions, respectively. The residual set-up errors decreased gradually with increasing verification frequency. In the case of daily image-guided verification, the residual set-up errors in x, y, and z directions decreased to (1.63±0.90), (1.63±0.93), and (1.55±0.90)mm, respectively. The reference values of PTV margins calculated under different verification frequencies decreased with an increase in the verification frequency. Under daily verification, the reference values of PTV margins calculated based on set-up errors decreased from initial 6.60, 6.29, and 4.22 mm (without correction) to 1.27, 1.37, and 1.28 mm, respectively. Differences in the reference values under verification frequencies every 3, 4, and 5 d were less than 0.81 mm. Conclusions:Daily image-guided verification (including correction) can effectively reduce set-up errors in image-guided radiotherapy for breast cancer. The set-up errors differ under varying verification frequencies, with a higher frequency corresponding to better correction effects and smaller PTV margins required.

Objective:To investigate the impact of postoperative complications on adverse outcomes following curative-intent resection for gallbladder cancer (GBC).Methods:The multi-center real-world study was conducted. The clinicopathological data of 629 patients with GBC, who were admitted to 14 medical centers including The First Affiliated Hospital of Army Medical University from the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, from April 2020 to April 2024 were collected. There were 225 males and 404 females, aged (64±10)years. Patients underwent open curative-intent resection for GBC. Observation indicators: (1)surgery, postoperative complica-tions and adverse outcomes; (2) analysis of risk factors affecting postoperative adverse outcomes in patients and population attributable fraction (PAF). Missing data in predictor variables were addressed using multiple imputation with chained equations, while cases with missing outcome variables were addressed using the "multiple imputation then deletion (MID)" strategy. The severity of multicollinearity among independent variables was assessed using the variance inflation factor (VIF) test. Multivariable possion regression models with log link and robust error variance were construc-ted incorporating restricted cubic splines (3 knots) to address nonlinear relationships in continuous variables, calculating adjusted relative risk ( RR) with corresponding 95% confidence interval ( CI). Adjusted PAF was calculated for each imputed dataset using the AF package of R software, with subsequent pooling performed according to Rubin's rules. Results:(1) Surgery, postoperative complications and adverse outcomes. All 629 patients underwent curative-intent resection for GBC, of which 143 cases had postoperative complications, including 68 cases of intra-abdominal ascites, 39 cases of pulmonary infection, 21 cases of bile leakage, 12 cases of intra-abdominal hemorrhage, 11 cases of liver failure, 10 cases of pan-creatic fistula, 10 cases of wound infection, 10 cases of gastroparesis, 7 cases of cholangitis, 7 cases of sepsis. The same patient could have more than one kind of complication. Of 629 patients, there were 19 cases of postoperative 90-day death and 11 cases of missing data, 42 cases with post-operative 90-day reoperation and 7 cases with missing data, 44 cases with postoperative 90-day readmission and 3 cases with missing data, 155 cases with prolonged postoperative hospital stay and 3 cases with missing data. (2) Analysis of risk factors affecting the postoperative adverse outcomes in patients and PAF. Results of multivariate analysis showed that pulmonary infection and liver failure were independent risk factors for postoperative 90-day mortality ( RR=3.74, 12.15, 95% CI as 1.18-11.83, 1.98-74.48, P<0.05). Pulmonary infection demons-trated the highest PAF as 4.61% (95% CI as 3.94%-5.28%, P<0.05). Intra-abdominal ascites, pulmonary infection, bile leakage, and intra-abdominal hemorrhage were independent risk factors for post-operative 90-day reoperation ( RR=4.80, 3.62, 3.46, 4.99, 95% CI as 2.49-9.26, 1.42-9.21, 1.34-8.92, 1.55-16.06, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 8.65% (95% CI as 8.22%-9.08%, P<0.05). Intra-abdominal ascites, bile leakage, and liver failure were independent risk factors for postoperative 90-day readmission ( RR=6.20, 3.33, 14.33, 95% CI as 3.21-11.95, 1.33-8.35, 3.72-55.28, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 9.11% (95% CI as 8.85%-9.37%, P<0.05). Intra-abdominal ascites, pulmonary infection, bile leakage, liver failure, and wound infection were independent risk factors for prolonged postoperative hospital stay ( RR=2.29, 2.21, 2.26, 2.14, 3.35, 95% CI as 1.63-3.23, 1.41-3.46, 1.32-3.86, 1.11-4.13, 1.70-6.60, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 6.03% (95% CI as 5.71%-6.35%, P<0.05). Conclusion:Pulmonary infection is the most significant risk factor for postoperative 90-day mortality after curative-intent resection for GBC, while intra-abdominal ascites is the most significant risk factor for postoperative 90-day reoperation, postoperative 90-day readmission, and prolonged postoperative hospital stay.

Objective:To evaluate the differences in total effectiveness, Visual Analogue Scale (VAS) scores, and Cox Menstrual Symptom Scale (CMSS) scores among four non-invasive Traditional Chinese Medicine (TCM) techniques: moxibustion, massage therapy, acupoint application, and auricular acupressure, for the care of primary dysmenorrhea (PD) using network Meta-analysis, providing evidence-based guidance for clinical decision-making.Methods:Randomized controlled trials (RCTs) involving the four non-invasive TCM techniques for PD care were retrieved from databases including China National Knowledge Infrastructure, VIP, Wanfang, SinoMed, PubMed, Embase, Web of Science, and Cochrane Library up to November 30, 2023. Network Meta-analysis was conducted using RevMan 5.4 and Stata 17.0.Results:A total of 83 studies involving 8 370 PD patients were included. The network Meta-analysis showed that all four TCM techniques were superior to control measures in terms of total effectiveness and reducing VAS scores. Moxibustion, acupoint application, and auricular acupressure were also superior in reducing CMSS scores. Ranking of the effects of different interventions: total effectiveness: auricular acupressure > moxibustion > acupoint application > massage therapy > acupuncture > Chinese patent medicine > Western medicine > blank control > placebo treatment; VAS scores: moxibustion > auricular acupressure > acupoint application > acupuncture > placebo treatment > massage therapy > Western medicine > Chinese patent medicine > blank control; CMSS scores: auricular acupressure > moxibustion > acupuncture > placebo treatment > acupoint application > Western medicine > blank control.Conclusions:The four non-invasive TCM techniques have significant advantages in PD care, with auricular acupressure and moxibustion being the preferred choices for clinical care.

BACKGROUND:Hydrogels have become a research hotspot due to their unique advantages in the biomedical field due to their superior mechanical and biological properties.At present,related research involves tissue engineering,wound dressing and so on. OBJECTIVE:To review the advantages and properties of hydrogels and the research progress of their application in the repair of oral and maxillofacial defects,discuss the current limitations and challenges of hydrogels in application and promotion,and provide new ideas for future research directions. METHODS:Relevant literature was searched in PubMed,CNKI,and WanFang database by computer.The search terms were"hydrogel,oral and maxillofacial defects,mechanical properties,tissue engineering,wound dressing"in Chinese and"hydrogel,oral and maxillofacial defects,mechanical properties,guided tissue regeneration,wound dressing"in English.Preliminary screening was carried out by reading titles and abstracts,and articles not related to the topic of the article were excluded.According to the inclusion and exclusion criteria,108 articles were finally included for the result analysis. RESULTS AND CONCLUSION:(1)The hydrogel has good biological activity,mechanical controllability,and stimulation response.(2)Polymer,metal,and ceramic hydrogel composites have appropriate mechanical properties,biodegradability,and controlled release rate,which are suitable for maxillofacial bone tissue engineering.(3)Fibrin-based hydrogel could fill the hollow nerve conduit through the nerve defect area and promote the regeneration and growth of axons to restore the function of maxillofacial nerve.(4)Controlling the interaction between nanomaterials and hydrogels can improve the formation of muscle fiber oriented structure to promote maxillofacial muscle tissue regeneration.(5)Polysaccharide hydrogel has gradually become the first choice for repairing irregular periodontal defects due to its ability to control drug delivery,carry bioactive molecules,and combine with other materials to produce the best scaffold matching the extracellular matrix.(6)Calcium phosphate or calcium carbonate-based hydrogels can be used to fill irregular or fine tissue defects and remineralize hard tissues.The self-assembled hydrogels are simple to prepare and have good biological activity.(7)Salivary gland-derived extracellular matrix-like gel is expected to participate in the treatment of many salivary gland diseases.(8)Hydrogels can be used as wound dressings in combination with biological adhesives,acellular biomaterials,antimicrobials,antioxidants,or stem cells to treat various wounds.(9)Fibrin-based hydrogel has the most potential in the repair of oral and maxillofacial defects.It has excellent biocompatibility,flexibility,and plasticity.It can combine with cells,extracellular matrix proteins,and various growth factors,and promote the osteogenic differentiation of mesenchymal stem cells,axon regeneration and growth,angiogenesis,myotube differentiation,salivary gland tissue regeneration,and periodontal tissue regeneration.It has a broad prospect in the repair of oral and maxillofacial defects.However,its therapeutic effect depends on the function of the substance carried.The complex preparation process,its safety and long-term efficacy,and the special anatomical oral and maxillofacial structure is the problem that hinders its promotion,which also provides directions for future research.

ObjectiveTo study the regulatory effect of the partial sequence within the 3’ untranslated region （3’UTR） of slit guidance ligand 1 （Slit1） （Slit1-3’UTR） on the fibrotic phenotypes of cardiac fibroblasts （CFs） and its potential mechanism. MethodsThe adenovirus vector was used to overexpress the 1526nt sequence of Slit1-3’UTR in ICR neonatal mouse CFs （mCFs）. The expression of fibrosis-related genes in mCFs， such as collagen type 1 alpha1（COL1A1）， collagen type 3 alpha3 （COL3A1） and alpha smooth muscle actin （α-SMA） were detected by Western blot assay. The effect of Slit1-3’UTR 1526nt on the proliferation and migration of mCFs was assessed by EdU staining and Trans-well assays. Angiotensin Ⅱ （Ang Ⅱ） was used to treat mCFs， and the impact of Slit1-3’UTR 1526nt on the fibrotic phenotypes of Ang Ⅱ-induced mCFs was evaluated. After overexpression of Slit1-3’UTR 1526nt， miR-34a-5p mimic was transfected into mCFs， followed by actinomycin D treatment to detect the mRNA stability of Slit1-3’UTR 1526nt， and the levels of miR-34a-5p and its target gene SIRT1（si-SIRT1） in mCFs were determined. The effects of miR-34a-5p and small interfering RNA targeting SIRT1 on the Slit1-3’UTR 1526nt-mediated regulation of fibrotic phenotypes were also determined. ResultsAdenovirus-mediated overexpression of Slit 1-3’UTR 1526nt was achieved in mCFs. Overexpression of Slit 1-3’UTR 1526nt markedly inhibited the expression of the fibrosis-related genes， proliferation and migration of mCFs and fibrotic phenotypes of Ang Ⅱ. The results of actinomycin D assay showed that miR-34a-5p inhibited the stability of Slit1-3’UTR 1526nt in mCFs， while the level of miR-34a-5p was reduced in mCFs with overexpression of Slit1-3’UTR 1526nt. Transfection of miR-34a-5p promoted the fibrotic phenotypes， and reversed the inhibitory effect of Slit1-3’UTR 1526nt on the fibrotic phenotypes of mCFs. Overexpression of Slit1-3’UTR 1526nt significantly increased the level of miR-34a-5p target gene SIRT1 in mCFs. Transfection of miR-34a-5p and si-SIRT1 consistently reversed the inhibitory effects of Slit1-3’UTR 1526nt on the fibrotic phenotypes of mCFs. ConclusionSlit1-3’UTR1526nt inhibits the fibrotic phenotypes of mCFs by binding to miR-34a-5p and increasing the expression of its target gene of SIRT1.

ObjectiveTo evaluate the clinical efficacy and safety of acupuncture combined with levodopa in the treatment of Parkinson's disease（PD）. MethodsA total of 60 patients with PD were enrolled and randomly assigned to test group or control group， with 30 patients in each group. The control group received levodopa only， starting at 100 mg per dose， three times daily， with gradual increases not exceeding a maximum daily dose of 800 mg. The test group received acupuncture three times per week in addition to levodopa. Both groups were treated for 12 weeks. Assessments were conducted before treatment， after 6 and 12 weeks treatment， using the Unified Parkinson's Disease Rating Scale（UPDRS）， Wearing-Off Questionnaire-9（WOQ-9）， Montreal Cognitive Assessment（MoCA）， Mini-Mental State Examination（MMSE）， Depression Rating Scale（DRS）， Hamilton Depression Scale（HAMD）， Hamilton Anxiety Scale（HAMA）， PD Questionnaire-39（PDQ-39）， and Pittsburgh Sleep Quality Index（PSQI）. Repeated measures ANOVA was utilized to evaluate the effects of time， group， and their interaction on each index. Spearman correlation analysis was conducted to examine the relationships between combined treatment and outcome scores. Adverse events in both groups were recorded throughout the study. ResultsBoth groups showed significant improvements after 6 and 12 weeks treatment， with decreases in UPDRS total score， WOQ-9 total score， DRS score， HAMD score， HAMA score， PDQ-39 score， and PSQI score， and increases in MoCA and MMSE scores（P＜0.05）. Compared with the control group， the test group demonstrated significantly greater improvements in all the above indicators after 6 and 12 weeks （P＜0.05）. Repeated measures ANOVA showed significant time main effects， group main effects， and their interaction across all outcome measures（P＜0.01）. Spearman correlation analysis revealed that combined therapy was significantly negatively correlated with UPDRS， WOQ-9， DRS， HAMD， HAMA， PDQ-39， and PSQI scores， while positively correlated with MoCA and MMSE scores after 12 weeks of treatment（P＜0.05）. Both groups did not experience any serious adverse events and did not affect treatment. ConclusionAcupuncture combined with levodopa is more effective than levodopa alone in improving motor function， non-motor symptoms， cognitive function， depression and anxiety， quality of life， and sleep quality in patients with PD， with good safety.
