ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

Compared with those in control group after treatment， there was no statistically significant difference in the improvement of APRI score and FIB-4 index level in the observation group after two treatment courses， and the APRI score in the observation group was more obvious after four treatment courses （P<0.05）， with no statistically significant improvement in the FIB-4 index difference. Compared with those before treatment， the levels of TCM syndrome scores decreased in both groups after two and four treatment courses （P<0.05）. Compared with that of the control group after treatment， there was no statistically significant difference in the improvement of the level of TCM syndrome scores in the observation group after two treatment courses， and the improvement of the level of TCM syndrome scores in the observation group was more obvious after four treatment courses （P<0.05）. Compared with those before treatment， the UWDRS-Ⅱ scores in both groups after two treatment courses were not improved obviously， and the UWDRS-Ⅱ scores in both groups decreased after four treatment courses （P<0.05）. Compared with those of the control group after treatment， there was no statistically significant difference in the improvement of the UWDRS-Ⅱ scores in the observation group after two treatment courses， and the improvement of the UWDRS-Ⅱ scores in the observation group after four treatment courses was more obvious （P<0.05）. Compared with those before treatment， the 24-h urine copper levels were significantly higher in both groups after two and four treatment courses （P<0.05）. Compared with those in the control group after treatment， the 24-h urine copper levels in the observation group were significantly higher after two and four treatment courses （P<0.01）. After two treatment courses， the 24-h urine copper level in the observation group showed a gradual decreasing trend， although it was higher than that before treatment. After four treatment courses， the control group had an improvement rate of 91.43%， an effective rate of 34.29%， and an apparent rate of 2.86%. The observation group had an improvement rate of 94.29%， an effective rate of 71.43%， and an apparent rate of 8.57%. The efficacy of the observation group was better than that of the control group （P<0.05）. Conclusion① The efficacy of GDFMD combined with DMPS therapy in patients with WD-related liver fibrosis of liver-kidney deficiency and phlegm-blood stasis syndrome is significantly better than that of single DMPS therapy， and the advantages of the combined therapy are more obvious with the prolongation of the treatment cycle. ② GDFMD combined with the DMPS therapy program in the long-term application exhibits no obvious adverse reactions with good safety， which is worthy of clinical popularization and application.

Objective To investigate the distribution characteristics of Oncomelania hupensis snails in Yunnan Province fol-lowing interruption of schistosomiasis transmission, so as to provide the evidence for assessing the risk of schistosomiasis transmission and scientifically formulating the schistosomiasis surveillance program. Methods According to the requirements of the National Schistosomiasis Surveillance Scheme (2020 Edition), O. hupensis snail surveillance data were collected from 18 schistosomiasis-endemic counties (cities, districts) in Yunnan Province from 2020 to 2024, including area of snail survey, area of snail habitats, area of re-emerging snail habitats, number of frames surveyed, number of frames with O. hupensis snails, number of O. hupensis snails captured, and number of living snails, and the occurrence of frames with snails and mean density of living snails were calculated. Changes in snail status over the 5-year period from 2020 to 2024 and the differences in snail distributions specified by epidemic intensity, environmental type, and vegetation type were analyzed. Results The areas of snail survey increased from 1 727.96 hm² in 2020 to 3 894.45 hm² in 2024 (peak) across 18 schistosomiasis-endemic counties (cities, districts) in Yunnan Province during the period from 2020 through 2024. The areas of snail habitats increased from 70.36 hm² in 2020 to a peak in 2023 (172.04 hm²), followed by a reduction to 132.36 hm² in 2024, and the areas of re-emerging snail habitats increased from 42.71 hm² in 2020 to a peak in 2022 (78.43 hm²), followed by a reduction to 40.21 hm² in 2024. The occurrence of frames with snails and mean density of living snails increased from 1.24% (3 025/244 404) and (0.033 2 ± 0.038 7) snails/0.1 m² in 2020 to peaks at 2.03% (6 231/307 563) and (0.066 9 ± 0.068 4) snails/0.1 m² in 2023, followed by reductions to 1.04% (5 829/559 941) and (0.032 6 ± 0.057 7) snails/0.1 m² in 2024, respectively. There was a significant difference in the occurrence of frames with snails over the 5-year study period (χ² = 1 962.95, P < 0.05), and the occurrence of frames with snails reduced by 48.71% in 2024 relative to in 2023 (χ² = 1 411.05, P < 0.005); however, there was no significant difference in the mean density of living snails over the 5 years (H = 5.310, P > 0.05). There were significant differences in the occurrence of frames with snails (χ² = 481.27, P < 0.05) and mean density of living snails (H = 6.872, P < 0.05) in schistosomiasis-endemic areas with different epidemic intensities. The occurrence of frames with snails (χ² = 25.32 and 38.70, both P values < 0.017) and mean density of living snails (Z = 28.55 and 49.96, both P values < 0.017) were higher in schistosomiasis transmission-interrupted and eliminated areas with snails than in schistosomiasis-eliminated areas without snails, and the occurrence of frames with snails (χ² = 453.54, P < 0.017) and mean density of living snails (Z = −56.97, P < 0.017) were higher in schistosomiasis-eliminated areas with snails than in schistosomiasis transmission-interrupted areas with snails. O. hupensis snails were mainly distributed in paddy fields, dry farmlands and ditches; however, the occurrence of frames with snails (13.40%, 424/3 164) and mean density of living snails [(0.252 8 ± 0.158 7) snails/0.1 m²] were higher in ponds/weirs than in other types of environments (both P values < 0.05). Rice, dry farmland crops and weeds were main vegetations in which O. hupensis snails were distributed, and the occurrence of frames with snails (2.29%, 7 111/310 140) and mean density of living snails [(0.072 3 ± 0.018 9) snails/0.1 m²] were higher in weeds than in other types of environments (both P values < 0.05). Conclusions O. hupensis snails have been effectively controlled in Yunnan Province following implementation of integrated schistosomiasis control measures; however, there are still risk factors for schistosomiasis transmission, including reduced attention to schistosomiasis control and snail re-emergence. Improved control efforts and surveillance system construction and timely identification of risk factors of snail status and timely management are recommended to ensure the achievement of the target of schistosomiasis elimination as scheduled.

Objective To investigate the prevalence of Schistosoma japonicum infections in wild murines in schistosomiasisendemic areas of Yunnan Province, so as to provide the evidence for improving the schistosomiasis surveillance and early warning capability and implementing precise interventions in the province. Methods A total of 56 natural villages were sampled from 14 schistosomiasis-endemic counties (cities, districts) in Yunnan Province as surveillance sites from 2024 to 2025. Wild murines were captured using traps at night and characterized for species. Liver samples were collected from wild murines, S. japonicum eggs and miracidia were simultaneously detected using liver tissue compression microscopy, liver tissue homogenate microscopy, and liver tissue homogenate hatching. In addition, stool samples were collected from wild murine rectum, with S. japonicum eggs detected using a modified Kato-Katz thick smear technique and S. japonicum miracidia detected using the hatching test with nylon gauzes. Results A total of 15 577 valid murine traps were recovered, and 891 wild murines belonging to 16 species were captured, with a capture rate of 5.72%(891/15 577). The captured wild murines were predominantly districted in paddy fields, dry lands, ditches, ponds and marshlands, with Apodemus chevrieri, Rattus norvegicus, Crocidura attenuata, R. rattus sladeni, R. flavipectus, and Eothenomys miletus as dominant species. No S. japonicum eggs or miradicia were in laboratory; however, other parasites were identified in 25 wild murines. The prevalence rates of Schistosoma sinensis, Capillaria hepatica and Hymenolepis nana were 2.24% (20/891), 0.90% (8/891) and 0.56% (5/891), and the prevalence of S. sinensis and C. hepatica co-infection was 0.90% (8/891), respectively. Conclusions S. sinensis, C. hepatica and H. nana are predominant parasite species in wild murines in schistosomiasis-endemic areas of Yunan Province. No S. japonicum infection was detected during the study period; however, there is still a risk of wild murines as a potential source of infection for schistosomiasis transmission. Continuous intensified surveillance of S. japonicum infections in wild murines is a critical programme in schistosomiasis surveillance and early warning in Yunnan Province.

OBJECTIVE To provide evidence for further improving the rules governing the renewal round of national centralized drug procurement with volume-based purchasing （VBP） program for insulin.METHODS Based on publicly available policy documents， selection outcomes， and interview data， policy text analysis， descriptive statistical analysis， the Wilcoxon signed-rank test， and thematic analysis were used to compare the procurement rules and selection outcomes between the initial and renewal rounds of the national VBP programs for insulin， and to examine the mechanisms linking rule adjustments to changes in selection outcomes.RESULTS Compared with the initial round， the renewal round retained the six procurement groups and 11 bidding units， reduced the maximum valid bid price by 40%， and introduced competitive bidding selection， revival selection， and a price line for Category A products. A total of 42 products were selected in the initial round and 49 in the renewal round， including 37 that remained selected， 5 that exited， and 12 that were newly selected in the renewal round. Within the same procurement groups， the price range decreased significantly in the renewal round compared with the initial round （ P ＝0.031）， whereas the difference in average price between the two was not statistically significant （ P ＝0.063）. Domestic manufacturers were more likely to enter the A1 category， whereas multinational manufacturers were more likely to remain in categories B/C. Mechanism analysis suggested that the price line shaped the boundary of selected prices， while the classification and volume-allocation rules linked manufacturers’ bidding decisions to expected procurement volumes， potentially altering bidding incentives and corresponding to changes in the distribution of selection outcomes.CONCLUSIONS The renewal round of the insulin VBP program established an interrelated mechanism involving price boundaries， volume-based incentives， and supply constraints through the use of price lines， product classification， and contracted volume allocation. These rule adjustments corresponded to changes in the structure of selected products， price distributions， and manufacturer classifications. Future policy refinement should strengthen the coordination among reasonable price ranges， volume-based incentives， and supply performance.

Objective: To analyze the epidemiological characteristics and spatio-temporal clustering characteristics of pulmonary tuberculosis (PTB) among the elderly population in Zhuji City, Zhejiang Province from 2014 to 2024, so as to provide the evidence for formulating differentiated PTB prevention and control measures for the elderly population. Methods: Data of PTB cases aged ≥60 years in Zhuji City from 2014 to 2024 were collected from the Tuberculosis Management Information System of the China Disease Prevention and Control Information System. Descriptive epidemiological methods were used to analyze the distribution characteristics of PTB cases among the elderly population. The average annual percent change (AAPC) and annual percent change (APC) were used to analyze the trends in PTB registration rates among the elderly population from 2014 to 2024. Spatial autocorrelation analysis and spatio-temporal scan analysis were used to analyze the spatio-temporal clustering characteristics of PTB among the elderly population. Results: A total of 1 852 PTB cases aged ≥60 years were registered in Zhuji City from 2014 to 2024, with an average annual registration rate of 59.82/105, showing an overall declining trend (AAPC=-3.494%, P<0.05). The registration rate showed a downward trend from 2014 to 2020 (APC=-8.709%, P<0.05), while trend in the registration rate from 2020 to 2024 was not statistically significant (P>0.05). The majority cases were males and farmers, with 1 395 and 1 446 cases respectively, accounting for 75.32% and 78.08%. Spatial autocorrelation analysis showed that PTB among the elderly population showed spatial clustering distribution in 2015 and 2023, with Moran's I values of 0.249 and 0.323, respectively (both P<0.05). High-high clustering areas were predominantly located in estern and northern parts of the city, while low-low clustering areas concentrated in the southeastern area. Spatio-temporal scan analysis showed that there was one spatio-temporal clustering area of PTB among the elderly population, concentrated central, western, and northern regions of Zhuji City, with the clustering period spanning from April 2014 to September 2019. Conclusions The registration rate of PTB among the elderly population in Zhuji City from 2014 to 2024 showed an overall declining trend, with cases predominantly occurring among males and farmers. The clustered areas were mainly in the central, western, and northern parts of the city. It is recommended to strengthen PTB prevention and control for key populations in clustering areas.

Acute respiratory distress syndrome(ARDS)is a common respiratory emergency,but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures.Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS,but the application of hydrogen has flammable and explosive safety concerns.Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance,thus improving ARDS in patients and animal models.Coral calcium hydrogenation(CCH)is a new solid molecular hydrogen carrier prepared from coral calcium(CC).Whether and how CCH affects acute lung injury in ARDS re-mains unstudied.In this study,we observed the therapeutic effect of CCH on lipopolysaccharide(LPS)induced acute lung injury in ARDS mice.The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable,demonstrating a significant improvement compared to the untreated ARDS model group.CCH treatment significantly reduced pulmonary hemorrhage and edema,and improved pulmonary function and local microcirculation in ARDS mice.CCH promoted mitochon-drial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2(Trx2),improved lung mitochondrial dysfunction induced by LPS,and reduced oxidative stress damage.The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.
