Objective To evaluate the effectiveness of the integrated schistosomiasis control programme in Wuhan City from 2005 to 2023, so as to provide insights into precision control and elimination of schistosomiasis. Methods The integrated measures for schistosomiasis control implemented by health, agriculture, water resources, and forestry departments of Wuhan City, and the epidemiological data of schistosomiasis in Wuhan City were collected from 2005 to 2023, and the prevalence of human schistosomiasis, prevalence of Schistosoma japonicum infections in humans and bovines, areas of S. japonicum-infected snail habitats, areas of snail habitats in inner embankments, and actual areas of snail habitats were retrieved. In addition, the trends in prevalence of schistosomiasis in humans and livestock and snail status were evaluated in Wuhan City from 2005 to 2023 using Mann-Kendall test and a Joinpoint regression model. Results Mann-Kendall test revealed a tendency towards a decline in the prevalence of human schistosomiasis (Z = -4.41, P < 0.01), prevalence of S. japonicum infections in humans (Z = -4.89, P < 0.01) and bovines (Z = -4.50, P < 0.01), areas of S. japonicum-infected snail habitats (Z = -3.91, P < 0.01), areas of snail habitats in inner embankments (Z = -2.28, P = 0.02), and actual areas of snail habitats (Z = -5.95, P < 0.01) in Wuhan City from 2005 to 2023. Joinpoint regression analysis showed an average annual reduction of 8.58% in the prevalence of human schistosomiasis in Wuhan City from 2005 to 2023 [average annual percent change (AAPC) = -8.58%, 95% confidence interval (CI): (-10.02%, -6.65%), P < 0.01], with two joinpoints in 2013 and 2016, respectively, and the tendency towards a decline showed statistical significance during the period from 2013 through 2016 [annual percent change (APC) = -34.41%, 95% CI: (-40.36%, -20.01%), P < 0.01]. The prevalence of S. japonicum human infections appeared an average annual reduction of 51.91% in Wuhan City from 2005 to 2023 [AAPC = -51.91%, 95% CI: (-58.12%, -44.25%), P < 0.01], with two joinpoints in 2014 and 2017, respectively, and the tendency towards a decline showed statistical significance during the period from 2014 through 2017 [APC = -98.17%, 95% CI: (-99.17%, -90.87%), P < 0.01]. The prevalence of S. japonicum infections in bovines appeared an average annual reduction of 53.12% in Wuhan City from 2005 to 2023 [AAPC = -53.12%, 95% CI: (-59.65%, -42.44%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2014 through 2017 [APC = -98.63%, 95% CI: (-99.44%, -90.93%), P < 0.01]. The areas of S. japonicum-infected snail habitats appeared an average annual reduction of 47.09% in Wuhan City from 2005 to 2023 [AAPC = -47.09%, 95% CI: (-52.92%, -38.26%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2011 through 2014 [APC = -97.27%, 95% CI: (-98.65%, -88.06%), P < 0.01]. The areas of snail habitats in inner embankments appeared an average annual reduction of 4.45% in Wuhan City from 2005 to 2023 [AAPC = -4.45%, 95% CI: (-5.18%, -3.82%), P < 0.01], with three joinpoints in 2011, 2015 and 2018, respectively, and statistical significance was seen in the tendency towards a decline during the period from 2005 through 2011 [APC = -16.38%, 95% CI: (-20.15%, -14.25%), P < 0.01]. In addition, the actual areas of snail habitats appeared an average annual reduction of 2.65% in Wuhan City from 2005 to 2023 [AAPC = -2.65%, 95% CI: (-2.89%, -2.40%), P < 0.01], with a joinpoint in 2013, and the tendency towards a decline showed statistical significance during the period from 2013 through 2023 [APC = -4.06%, 95% CI: (-4.66%, -3.58%), P < 0.01]. Conclusions The integrated schistosomiasis control programme achieved significant effectiveness in Wuhan City from 2005 to 2023, with a tendency towards a decline in morbidity due to schistosomiasis in humans and livestock and snail status. The integrated schistosomiasis control strategy with emphasis on management of the source of S. japonicum infections should continue to be implemented to consolidate the schistosomiasis control achievements and achieve the goal of schistosomiasis elimination in the city.

Objective To explore the regulatory role of N-methyl berbamine(N-MB)in intracellular calcium homeostasis in H9c2 car-diomyocytes,and,thereby,clarify the possible mechanism of the myocardial protective effect of N-MB.Methods Binding of N-MB to CaV1.2 channels was simulated using the MOE software,and the binding affinity and binding mode were determined.The hCaV1.2 gene was transfected into HEK293 cells,and the effect of N-MB(30 μmol/L)on the CaV1.2 current was detected using the whole-cell patch clamp technique.In addition,a Fluo 3-AM fluorescent probe was loaded into H9c2 cardiomyocytes,and the effect of N-MB(3,30 μmol/L)on intracellular calcium ion concentration was observed under a laser confocal microscope.The effect of N-MB(3,30 μmol/L)on the expression of Ca2+regulation-related genes Cacna1c,Cacnb2,Ryr2,Serca2a,and Ncx1 in H9c2 cardiomyocytes was examined using real-time quantitative PCR.Results N-MB was predicted to bind to CaV1.2 channels.The binding sites mainly involved Phe1191,Thr1420,and Asn771,and the binding modes were H-donor,pi-pi,and pi-H.N-MB(30 μmol/L)significantly inhibited CaV1.2 currents,with an inhibition rate of 76.09％±7.41％.The fluorescence intensity of intracellular Ca2+level in H9c2 cardiomyocytes was significantly enhanced with N-MB treatment(3,30 μmol/L,P＜0.01).Compared with the control group,differences in the expression of Cacna1c,Serca2a,and Ncx1 in H9c2 cardiomyocytes were not significant after N-MB(3,30 μmol/L)intervention(P＞0.05),whereas the expression of Cacnb2 significantly reduced(P＜0.001)and the expression of Ryr2 significantly increased(P＜0.05).Conclusion N-MB binds to CaV1.2 calcium channels.N-MB may regulate intracellular calcium homeostasis by inhibiting calcium currents by decreasing the gene expression of CaV1.2 calcium channels.Additionally,N-MB may also increase intracellular Ca2+concentration by promoting the expression of Ryr2,which could be the mechanism underlying the myocardial protective effect of N-MB.

Objective:To investigate and summarize pediatric patients with severe Mycoplasma pneumoniae pneumonia (MPP) presenting with varied clinical and chest imaging features in order to guide the individualized treatment. Methods:This was a retrospective cohort study. Medical records of clinical, imaging and laboratory data of 505 patients with MPP who were admitted to the Department Ⅱ of Respirology Center, Beijing Children′s Hospital, Capital Medical University from January 2016 to October 2023 and met the enrollment criteria were included. They were divided into severe group and non-severe group according to whether lower airway obliterans was developed. The clinical and chest imaging features of the two groups were analyzed. Those severe cases with single lobe ≥2/3 consolidation (lobar consolidation) were further divided into subtype lung-necrosis and subtype non-lung-necrosis based on whether lung necrosis was developed. Comparison on the clinical manifestations, bronchoscopic findings, whole blood C-reactive protein (CRP) and other inflammatory indicators between the two subtypes was performed. Comparisons between two groups were achieved using independent-sample t-test, nonparametric test or chi-square test. Univariate receiver operating characteristic (ROC) curve analyses were performed on the indicators such as CRP of the two subtypes. Results:Of the 505 cases, 254 were male and 251 were female. The age of the onset was (8.2±2.9) years. There were 233 severe cases, among whom 206 were with lobar consolidation and 27 with diffuse bronchiolitis. The other 272 belonged to non-severe cases, with patchy, cloudy infiltrations or single lobe <2/3 uneven consolidation or localized bronchiolitis. Of the 206 cases (88.4%) severe cases with lobar consolidation, 88 harbored subtype lung-necrosis and 118 harbored subtype non-lung-necrosis. All 206 cases (100.0%) presented with persistent high fever, among whom 203 cases (98.5%) presented with inflammatory secretion obstruction and plastic bronchitis under bronchoscopy. Of those 88 cases with subtype lung-necrosis, there were 42 cases (47.7%) with dyspnea and 39 cases (44.3%) with moderate to massive amount of pleural effusion. There were 35 cases (39.8%) diagnosed with lung embolism during the disease course, of which other 34 cases (38.6%) were highly suspected. Extensive airway mucosal necrosis was observed in 46 cases (52.3%), and the level of their whole blood CRP was significantly higher than that of subtype non-lung-necrosis (131.5 (91.0, 180.0) vs. 25.5 (12.0, 43.1) mg/L, U=334.00, P<0.001). They were regarded as subtype "lung consolidation-atelectasis-necrosis". Of those 118 cases with subtype non-lung-necrosis, 27 cases (22.9%) presented with dyspnea and none were with moderate to massive amount of pleural effusion. Sixty-five cases (55.1%) presented with plastic bronchitis and localized airway mucosal necrosis was observed in 32 cases (27.1%). They were deemed as subtype "lung consolidation-atelectasis". ROC curve analyses revealed that whole blood CRP of 67.5 mg/L on the 6-10 th day of disease course exhibited a sensitivity of 0.96, a specificity of 0.89, and an area under the curve of 0.97 for distinguishing between these two subtypes among those with lobar consolidation. Conclusions:Pediatric patients with severe MPP present with lobar consolidation or diffuse bronchiolitis on chest imaging. Those with lobar consolidation harbor 2 subtypes as "lung consolidation-atelectasis-necrosis" and "lung consolidation-atelectasis". Whole blood CRP of 67.5 mg/L can be applied as an early discriminating indicator to discriminate between these two subtypes.

Osteosarcoma of the jaw (JOS), is a relatively rare type of osteosarcoma, with a unique pathogenesis and pathological manifestations. The clinical manifestation of JOS is not characteristic, and it often needs to be diagnosed by combining radiological and pathological examination. At present, the conventional treatment of JOS is a comprehensive treatment based on surgery and supplemented by radiotherapy and chemotherapy. Recently, the emergence of new therapies such as immunotherapy, gene therapy, phototherapy and traditional Chinese medicine has provided more choices for treatment and brought new hope to patients with JOS. Therefore, this article summarized the current understanding of diagnosis and the latest treatment development of JOS.

Objective To verify the mental health status and methods to regulate emotion as well as identify the associated factors among Northwest University students during the lockdown period of the COVID-19 outbreak in Xi'an.Methods A questionnaire survey using the random sampling was conducted among the college students in Xi'an,using Self-Control Scale(SCS),Perceived Social Support Scale(PSSS),the Depression-Anxiety-Stress Scale Lite(DASS-21),and Self-Rating Scale of Sleep(SRSS).Results A total of 512 valid questionnaires for college students were collected.The statistical results showed that during the lockdown period after the COVID-19 epidemic outbreak in Xi'an,there were gender and discipline differences in self-control and understanding of social support among college students.That is,compared with boys,girls were more likely to receive social support(P=0.031),friend support(P=0.008),and other support(P=0.029).Compared to liberal arts majors,college students majoring in science and engineering were more likely to engage in self-control,especially in healthy habits(P=0.001),moderate entertainment(P=0.002),and impulse control(P=0.001).However,there was no significant difference in the influence of students'age or whether they came from rural or urban areas on their self-control and understanding of social support abilities.The statistical results also found that the age of college students was significantly correlated with their level of stress and sleep status.Their self-control ability and ability to comprehend social support also had correlation with their mental health status and sleep status during the lockdown period of the epidemic.Conclusion College students were prone to have negative emotions and sleep disorders during the lockdown period of sudden epidemic,which were more common in senior grades,male college students,and liberal arts majors.Active self-control and seeking social support can effectively moderate negative emotions and sleep disturbances.

Objective　To analyze and visualize the epidemic changes of schistosomiasis in Wuhan from 2013 to 2022 based on a geographical information system (GIS), providing references for further schistosomiasis control activities. Methods　According to the historical data of the annual reports of schistosomiasis screening and street-level vector map of Wuhan City from 2013 to 2022, a spatial database of epidemic information at the street level was established. The Joinpoint regression model was utilized to analyze the trend of phased changes in blood positivity rate for schistosomiasis. ArcMap 10.8 was employed for the spatial visualization of the positive rate of serological tests for schistosomiasis among the screened population in the endemic areas of Wuhan over the past decade, as well as conducting hot spot analysis (Getis-Ord Gi*) to explore the spatial clustering relationship and spatiotemporal trends. Heatmaps were generated to reflect the changes in the positive rate of blood tests for schistosomiasis over a decade in various streets, and the areas were classified by the ward’s method of hierarchical clustering using the sum of squared deviations. Results　Over the past decade, the overall annual positive rate of schistosomiasis screening in Wuhan declined from 2.23% in 2013 to 0.47% in 2022, showing a general downward trend. The Joinpoint regression model analysis of the blood positive rate indicated the presence of one connection point in 2015; from 2013 to 2015, the annual percent change (APC) of the positive rate was 2.17%, showing an upward trend (P>0.05); from 2015 to 2022, the APC was -23.34%, indicating a downward trend (P<0.05). The map of positive street-level schistosomiasis screening rates for 2013-2022 shows that the positive rate count on the streets of Caidian District and Hannan District in southwestern Wuhan and Huashan Street on the east side, had a significant decrease over the ten years, while the rate in the streets under the jurisdiction of Dongxihu District in the west showed an increase. The hot spot analysis graph revealed that hot spots of the positive rate in Wuhan shifted from the southwest to the west beginning in 2018. The heatmap indicated the largest disparity in trend changes, with the most noteworthy decline in streets under Caidian District and an increasing trend in the streets under Dongxihu District. Conclusions　The overall epidemic situation of schistosomiasis in Wuhan is on a downtrend, although the positive rate of blood tests has increased in some areas. This has been attributed to a reduction in the total number of people participating in the blood tests and the slow decrease of antibodies in certain patients who were repeatedly sampled for testing. It is important to further strengthen the construction of monitoring capabilities, improve the sensitivity of monitoring systems, identify potential risks promptly, and handle them properly.
