Objective:
To analyze the surveillance data of schistosomiasis and snail status in Jiaxing City, Zhejiang Province from 2001 to 2024, so as to provide the reference for prevention and control of schistosomiasis in jiaxing City.
Methods:
Data on schistosomiasis and snail surveillance in Jiaxing City from 2001 to 2024 were collected through schistosomiasis control work reports and the Zhejiang Provincial Schistosomiasis (Parasitic Diseases) Control Information Management System. These data included serological testing results, stool etiological examination (stool examination) results, area surveyed for snails, snail-infested areas, number of snail-positive frames, and number of live snails. Indicators, including the positive rate of serological testing, the positive rate of stool examinations, the rate of snail-positive frames, and the density of live snails were analyzed. The Prophet time series model was employed to forecast the schistosomiasis epidemic in Jiaxing City from 2025 to 2029.
Results:
A total of 636 493 serological testing were conducted in Jiaxing City from 2001 to 2024, with a positive rate of 1.532%, showing a decreasing trend (P<0.05). Among 7 582 stool examinations, positive cases were all imported, resulting in a positivity rate of 0.066%. During the same period, snail surveys covered a cumulative area of 30 545.999 hm2, with snail-infested areas totaling 69.355 hm2; no significant trend was observed (P>0.05). All snail habitats were identified as recurrent foci within hydrographic network regions, primarily distributed across Xiuzhou District, Nanhu District, Pinghu City, Jiashan County, and Tongxiang City, with snail-infested areas of 39.588, 12.538, 10.728, 4.315, and 2.186 hm2, respectively. From 2009 to 2024, a total of 35 692 134 frames of snails were surveyed, of which 16 543 were snail-positive, yielding a snail-positive frame rate of 0.046%. A total of 33 175 live snails were collected, with a mean density of 0.000 98 snails per frame. No infected Oncomelania snails were detected. The projection results indicated that from 2025 to 2029, the positive rate of serological testing rate in Jiaxing City would range between 0.253% to 0.389%, the snail-infested areas would range from 0.025 to 1.818 hm2, and the density of live snails would vary from 0.001 56 to 0.001 66 snails per frame. None of these indicators showed a significant trend (all P>0.05).
Conclusions
From 2001 to 2024, the positive rate of serological testing rate of schistosomiasis in Jiaxing City showed a declining trend, with no new autochthonous cases or infected Oncomelania snails detected. However, imported cases were still reported. All identified snail habitats were recurrent foci within hydrographic network regions. It is recommended to enhance schistosomiasis and snail status surveillance in high-risk areas.

Objective: To explore the efficacy of vonoprazan fumarate in the treatment of laryngopharyngeal reflux disease(LPRD) evaluated by the Chinese version of the RSS-12 scale. Methods:A total of 100 LPRD patients treated in the otolaryngology-head and neck surgery outpatient clinic of our hospital were randomly divided into two groups(50 cases each). The observation group was treated with vonoprazan fumarate(20 mg, once daily), and the control group was treated with esomeprazole enteric-coated capsules(20 mg, twice daily) for 12 weeks. The selected observation indicators in this study included RSI, the Chinese version of RSS-12, and RFS scores before and after treatment. Results:Prior to treatment, there was no statistically significant difference in the Chinese version of RSS-12, RSI, and RFS between the two groups(P>0.05). After 8 and 12 weeks of antacid treatment, both the Chinese version of RSS-12 and RSI significantly decreased in both group (P<0.05). The changes in symptoms were particularly noticeable between 0-8 weeks of treatment according to the Chinese version of RSS-12 and RSI. After 12 weeks of treatment, the RFS scores significantly decreased compared to pretreatment levels (P<0.05). After 12 weeks of antacid treatment, according to the Chinese version of RSS-12, 80% of patients in the observation group showed a good therapeutic response, compared to 64% in the control group; according to RSI, 90% of patients in the observation group showed a good therapeutic response, compared to 84% in the control group. There was no statistically significant difference in the treatment effect between the two groups after 12 weeks of treatment(P>0.05). Conclusion:Vonoprazan fumarate can significantly improve the symptoms and signs of laryngopharyngeal reflux, and their treatment effect is not inferior to proton pump inhibitors. Compared with RSI, the Chinese version of RSS-12 can serve as a new screening tool for clinical diagnosis of LPRD in China.

ObjectiveTo genotype Oncomelania hupensis, based on microsatellites, in different snail-bearing environments in Jiaxing City, Zhejiang Province, for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village (YB) and Sanxing Village (SX) in Pinghu City, and Yunhe Farm (YH) in Xiuzhou District, all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed, and the mean number of alleles (Na) was 7.889, 5.667, and 3.778 for YB, SX, and YH respectively; the number of effective alleles (NeA) was 4.807, 3.329, and 2.294, respectively; and the coefficients of inbreeding (FIS) were 0.400, 0.377, and 0.493, respectively. Under the Infinite Allele Model (IAM), the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes (Ne) were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals, accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations (FST) was 0.286, indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent, and the three populations were divided into two lineages, YB and SX were one lineage, and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient, population divergence history indicated that YH might have diverged from SX first, and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low, and the snail populations are unstable, with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.

Objective:To investigate the epidemiological characteristics of herpangina (HA) and its correlation with the incidence of hand, foot and mouth disease (HFMD) in children aged ≤6 years in Yinzhou District of Ningbo from 2017 to 2022.Methods:Epidemiological characteristics of HA in children aged ≤6 years were analyzed based on the electronic medical record data and public health management data from 2017 to 2022 collected from the Health Information Platform of Yinzhou. The incidence of HFMD was calculated using the infectious disease reporting data from the public health management data. Autoregressive integrated moving average model and cross-correlation function were used to evaluate the correlation between the incidence of HA and HFMD.Results:From 2017 to 2022, a total of 25 385 cases of HA were detected in children aged ≤6 years in Yinzhou, the male-to-female ratio of the cases was 1.12∶1. The average annual incidence of HA was 4 986.67/100 000, with the highest incidence in 2018 (10 477.09/100 000) and the lowest incidence in 2020 (870.88/100 000). The incidence peak of HA was during June to July. The incidence of HA was higher in age group 1 year (7 950.45/100 000) than in other age groups. The incidences of HA in Yunlong, Jiangshan and Xiaying were higher, with the incidence of 8 764.31/100 000, 8 377.58/100 000 and 7 965.31/100 000, respectively. The correlation coefficients between the incidence of HA and HFMD at lag day 0, 7, 12 and 18 were 0.199, 0.139, 0.090 and 0.086, respectively (all P<0.05). Conclusions:From 2017 to 2022, the incidence of HA was high in children aged ≤6 years in Yinzhou with obvious seasonality and area difference. The incidence of HA was correlated with the incidence of HFMD and the incidence of HFMD had certain lags. The comprehensive prevention and control of HA and HFMD should be further strengthened by prioritizing HA surveillance and implementing integrated surveillance and management of HA and HFMD.

Objective:To observe the physiological effect of bi-level positive airway pressure (BiPAP) ventilation among stable chronic obstructive pulmonary disease (COPD) patients.Methods:This was a small sample size, exploratory, interventional study. A total of 10 outpatients with stable COPD were included from Department of Pulmonary and Critical Care Medicine of Zhujiang Hospital, Southern Medical University between January 2018 and December 2018. The BiPAP mode of noninvasive mechanical ventilation was adopted. The inspiratory positive airway pressure was gradually increased from 10 cmH 2O (1 cmH 2O=0.098 kPa) to 24 cmH 2O, and each time by 2 cmH 2O. The expiratory positive airway pressure remained unchanged at 4 cmH 2O. Baseline and test data were collected before and during the ventilation for comparison, including total respiratory cycle time (T tot), inspiratory time (T i), inspiratory time (T e), inspiratory tidal volume (V Ti); mouth pressure (P mo), esophageal pressure (P eso), transdiaphragmatic pressure (P di), esophageal pressure time product (PTP es), diaphragm pressure time product (PTP di), root mean square of electromyography of diaphragm (RMS), V e/RMS, inspiratory capacity (IC), the change in end-expiratory lung volume (ΔEELV) and dynamic PEEPi (PEEPi dyn). Results:All the 10 patients completed the trial. Compared to calm breathing, V Ti, V e, P mo, IC, ΔEELV score and V e/RMS increased significantly with increasing pressure levels (all P<0.05); T e only increased significantly at 20-22 cmH 2O pressure levels compared to calm breathing ( P<0.05). P di, PTP es, PTP di, RMS and RMS/RMS max decreased significantly with increasing levels (all P<0.05). PTP es and PTP di converged to 0 and no longer showed significant changes after the 18 cmH 2O pressure level. RMS and RMS/RMS max flattened out at pressure level greater than 16 cmH 2O. T i/T tot only significantly decreased at the 20 cmH 2O pressure level compared to calm breathing. PEEPi dyn showed a tendency to decrease and then increase with increasing pressure levels. Conclusion:BiPAP ventilation, at appropriate pressure levels, significantly relieves pulmonary ventilation disorders and reduces the load of respiratory muscle in patients with stable COPD.

The nucleocapsid (N) protein of SARS-CoV-2 has been reported to have a high ability of liquid-liquid phase separation, which enables its incorporation into stress granules (SGs) of host cells. However, whether SG invasion by N protein occurs in the scenario of SARS-CoV-2 infection is unknow, neither do we know its consequence. Here, we used SARS-CoV-2 to infect mammalian cells and observed the incorporation of N protein into SGs, which resulted in markedly impaired self-disassembly but stimulated cell cellular clearance of SGs. NMR experiments further showed that N protein binds to the SG-related amyloid proteins via non-specific transient interactions, which not only expedites the phase transition of these proteins to aberrant amyloid aggregation in vitro, but also promotes the aggregation of FUS with ALS-associated P525L mutation in cells. In addition, we found that ACE2 is not necessary for the infection of SARS-CoV-2 to mammalian cells. Our work indicates that SARS-CoV-2 infection can impair the disassembly of host SGs and promote the aggregation of SG-related amyloid proteins, which may lead to an increased risk of neurodegeneration.

In vitro studies have established the prevalent theory that the mitochondrial kinase PINK1 protects neurodegeneration by removing damaged mitochondria in Parkinson's disease (PD). However, difficulty in detecting endogenous PINK1 protein in rodent brains and cell lines has prevented the rigorous investigation of the in vivo role of PINK1. Here we report that PINK1 kinase form is selectively expressed in the human and monkey brains. CRISPR/Cas9-mediated deficiency of PINK1 causes similar neurodegeneration in the brains of fetal and adult monkeys as well as cultured monkey neurons without affecting mitochondrial protein expression and morphology. Importantly, PINK1 mutations in the primate brain and human cells reduce protein phosphorylation that is important for neuronal function and survival. Our findings suggest that PINK1 kinase activity rather than its mitochondrial function is essential for the neuronal survival in the primate brains and that its kinase dysfunction could be involved in the pathogenesis of PD.

【Objective】 To investigate the unqualified rate of anti-HIV detection of blood screening laboratories in Beijing-Tianjin-Hebei region, and explore the differences in anti-HIV detection ability and influencing factors in each laboratory. 【Methods】 Through filling questionnaires via e-mail, the anti-HIV ELISA unqualified rate and confirmed (WB) positive results (data) from January to December 2018 from 15 blood screening laboratories in Beijing-Tianjin-Hebei region were collected. Our laboratory was responsible for data collection and confirmation, and statistics software SPSS22.0 was used for analysis. 【Results】 1) There was a statistically significant difference among the unqualified rate of anti-HIV ELISA(6.77‱~35.71‱) and confirmed positive rate(0.60‱~3.56‱) in 15 blood screening laboratories in Beijing-Tianjin-Hebei region (P<0.05); 2) There were significant differencse among the ELISA unqualified rate and the confirmed positive rate of 8 reagents for anti-HIV detection(P<0.01), and the sensitivity of the 4th generation detection reagent and the imported reagent was higher than that of the 3rd generation reagent and the domestic reagent. The anti-HIV ELISA unqualified rate of R5 was the highest (19.08‱). 3)There were significant differences in the anti-HIV ELISA unqualified rate of R1, R2, R3, R5 and R7 reagents among different blood station laboratories(P<0.05), and there were no significant differences in the anti-HIV ELISA unqualified rate of R4, R6 and R8 reagents among different blood station laboratories(P>0.05). 4)The unqualified rate of anti-HIV ELISA of laboratories using different regents showed significant differences(P<0.05), except H, J, M. The unqualified rate of imported reagent was significantly higher than that of domestic reagents of laboratories using imported and domestic reagents combinations(P<0.05), except O. 62.5% (5/8) laboratories using domestic 3rd and 4th generation reagent combination showed significant differences in the unqualified rates among different reagents(P<0.05); 5) The positive rate of single-reagent(62.02%~95.45%)in 15 blood screening laboratories showed significant difference(P<0.001), and A was the lowest (62.02%). 【Conclusion】 The anti-HIV detection ability among 15 blood screening laboratories in Beijing-Tianjin-Hebei region is quite different. The application of different reagents is the main factor for the difference, and other factors such as personnel, instruments and test strategies also has a great impact on the detection of anti-HIV. It is still necessary to promote the process of homogenization of blood testing quality among blood screening laboratories in Beijing-Tianjin-Hebei region.
