Objective To evaluate the effectiveness of schistosomiasis surveillance in Jiangsu Province during the stage moving from transmission control to transmission interruption, and to analyze the current risk and challenges, so as to provide the evidence for achieving the target of schistosomiasis elimination. Methods Schistosomiasis surveillance data were collected from Jiangsu Province from 2012 to 2024, and the endemic areas, Schistosoma japonicum infections in humans and livestock, Oncomelania hupensis snail distribution and implementation of integrated interventions were descriptively analyzed. In addition, the trends in areas with snails, seroprevalence of human S. japonicum infections and numbers of advanced schistosomiasis cases were assessed using a Joinpoint regression model. Results The endemic areas of schistosomiasis continued to shrink in Jiangsu Province from 2012 to 2024, with the number of schistosomiasis-eliminated counties (cities, districts) increasing from 53 (75.71%) to 63 (96.92%), and interruption of schistosomiasis transmission was achieved across the province. A total of 4 600 300 person-times were tested for serum antibodies against S. japonicum, with 28 719 person-times positive detected; and 616 500 person-times were tested S. japonicum infections among local residents in Jiangsu Province from 2012 to 2024, with only 3 egg-positives detected, and no egg-positives found since 2017. A total of 187 600 herd-times were tested for schistosomiasis in livestock, and no S. japonicum infections were found. O. hupensis snail survey was performed covering 1 018 408.97 hm2, and a total of 35 556.35 hm2 was found with snail-infested habitats, including 174.40 hm2 of emerging snail-infested habitats. A total of 1 102 800 O. hupensis snails were identified for S. japonicum infections, and no infections were found. The areas of snail-infested habitats appeared a tendency towards a rise in Jiangsu Province from 2019 to 2023 (APC = 23.67%, P < 0.05), and the actual areas of snail-infested habitats appeared a tendency towards a decline from 2012 to 2015 (APC = −22.77%, P < 0.05), and towards a rise from 2015 to 2023 (APC = 9.76%, P < 0.01). The seroprevalence of anti-S. japonicum antibodies appeared a tendency towards a decline among residents in Jiangsu Province from 2017 to 2023 (APC = −14.92%, P < 0.01). In addition, the number of newly diagnosed advanced schistosomiasis cases appeared a tendency towards a decline from 2012 to 2024 (APC = −12.02%, P < 0.01), and the numbers of advanced schistosomiasis patients requiring treatment showed a tendency towards a decline from 2012 to 2021 (APC = −10.56%, P < 0.01) and from 2021 to 2023 (APC = −20.06%, P < 0.01). Conclusions Great progresses had been achieved in schistosomiasis control in Jiangsu Province following transmission control, and transmission interruption had been achieved; however, there are still snail-infested habitats. High-intensity surveillance and integrated control are required to be maintained to advance the achievement of the target of schistosomiasis elimination in Jiangsu Province.

ObjectiveTo investigate the mechanism by which Jianpi Xiao'ai prescription (JPXAP) inhibits colorectal cancer progression by regulating the inducible nitric oxide synthase-arginase 1 (iNOS-ARG1) metabolic axis and inducing mitochondrial reactive oxygen species (mito-ROS)-mediated mitochondrial structural and functional impairment. MethodsAn arginine metabolism disorder model of human colorectal cancer HCT116 cells was established by combined treatment with recombinant human interferon-γ (IFN-γ, 10 μg·L-1) and N(ω)-hydroxy-L-arginine (Nor-NOHA, 200 μmol·L-1) for 24 h, followed by intervention with 5%, 10%, or 20% JPXAP-containing serum. Cell proliferation was assessed using cell counting kit-8 (CCK-8), 5-ethynyl-2′-deoxyuridine (EdU) staining, and colony formation assays. Cell invasion and migration were evaluated using Transwell chamber and wound healing assays. Mitochondrial membrane potential (MMP) and ROS levels were assessed by JC-1 and MitoSOX staining, respectively. Mitochondrial ultrastructure was observed by transmission electron microscopy (TEM). The expression of iNOS, ARG1, and mitochondrial dynamics-related proteins, including mitofusin 2 (MFN2) and dynamin-related protein 1 (DRP1), was analyzed by Western blot and immunofluorescence. The levels of L-arginine, citrulline, and urea were determined by colorimetric methods and enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the blank group, the model group exhibited significantly upregulated iNOS expression, downregulated ARG1 expression, a decreased ARG1/iNOS ratio, reduced L-arginine and urea levels, and increased citrulline levels (P<0.05). Meanwhile, mito-ROS accumulation was significantly increased, the JC-1 red/green fluorescence ratio was decreased, and mitochondria showed swelling and cristae disruption, indicating that metabolic disorder induced mitochondrial injury. Compared with the model group, all JPXAP-treated groups further decreased the ARG1/iNOS ratio, enhanced nitric oxide (NO) and reactive nitrogen species accumulation, further reduced L-arginine and urea levels, and increased citrulline levels (P<0.01). EdU-positive rate, colony formation rate, wound healing rate, and Transwell invasion number all decreased significantly with increasing serum concentration (P<0.01). Mito-ROS levels were further elevated, and the JC-1 red/green ratio further decreased. TEM revealed aggravated mitochondrial swelling and vacuolization. MFN2 expression was downregulated and DRP1 expression was upregulated (P<0.01),in a dose-dependent manner. ConclusionJPXAP further activates NO-mediated oxidative/nitrosative stress under arginine metabolism imbalance, inducing mito-ROS accumulation, MMP collapse, and mitochondrial dynamics imbalance, thereby inhibiting colorectal cancer cell proliferation and migration. These findings reveal an antitumor mechanism of JPXAP based on coordinated targeting of the "metabolism-mitochondria" axis.

Objective To examine the association between epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) and meteorological factors in Shenzhen City during the period from 2012 to 2019. Methods Average atmospheric pressure, average air temperature, average relative humidity, precipitation, wind speed, and sunshine duration were captured from Meteorological Bureau of Shenzhen City each month from 2012 to 2019. The average monthly rodent densities in Shenzhen City from 2012 to 2019 were acquired from the Vector Surveillance Management System of Guangdong Provincial Center for Disease Control and Prevention, and the monthly HFRS incidence was retrieved from Shenzhen Municipal Disease Surveillance System from 2012 to 2019. The correlation between meteorological factors and the monthly incidence of HFRS was examined us ing Spearman’s rank correlation in Shenzhen City, and the temporal trends in monthly HFRS incidence and the degrees of freedom for the rodent density were determined in Shenzhen City with a generalized additive model. The optimal lag time was identified using excess risk (ER) and its 95% confidence interval (CI), and univariate and multivariate models were fitted to evaluate the impact of meteorological factors on HFRS incidence in Shenzhen City. Results The median number of incident HFRS cases was 3.00 (interquartile range, 3.25) in Shenzhen City from 2012 to 2019, with an average air temperature of (23.44 ± 4.91) °C, average relative humidity of (76.05 ± 7.61)%, median precipitation of 4.10 (interquartile range, 6.83) mm, average wind speed of (1.97 ± 0.26) m/s, average sunshine duration of (5.17 ± 1.64) h, and median monthly rodent density of 1.74% (interquartile range, 2.52%). Spearman’s rank correlation analysis showed that the average air temperature positively correlated with average relative humidity (rs = 0.420, P < 0.05), precipitation (rs = 0.658, P < 0.05) and sunshine duration (rs = 0.633, P < 0.05), and the atmospheric pressure negatively correlated with average air temperature (rs = −0.925, P < 0.05), relative humidity (rs = −0.614, P < 0.05), precipitation (rs = −0.789, P < 0.05) and sunshine duration (rs = −0.437, P < 0.05), while the average relative humidity correlated positively with precipitation (rs = 0.724, P < 0.05) and negatively with sunshine duration (rs = −0.218, P < 0.05). Univariate modeling analysis showed that the ERs and their 95% CI were 0.639% (0.540%, 0.737%) for average atmospheric pressure, −7.157% (−8.113%, −6.190%) for average air temperature, −3.603% (−4.219%, −2.985%) for average relative humidity, −5.889% (−7.085%, −4.669%) forprecipitation,21.881% (−5.149%, 56.612%) for average wind speed, and −13.877% (−16.641%, −11.022%) for sunshine duation (all P values < 0.05). Multivariate modeling analysis showed that in the ensemble model combining average atmospheric pressure and precipitation, the highest ER (6.686%) was caused by increased average atmospheric pressure, and the highest absolute ER values for average air temperature (6.615%), average relative humidity (3.107%) and precipitation (5.386%) were seen after adjustment only for sunshine duration (all P values < 0.05), while the highest absolute ER for sunshine duration (11.875%) was found after adjustment for precipitation (P < 0.05). Conclusions An increase in average air temperature, relative humidity, precipitation and sunshine duration resulted in a reduced incidence rate of HFRS in Shenzhen City from 2012 to 2019, and an increase in average atmospheric pressure increased the incidence of HFRS. Meteorological factors are important determinants affecting HFRS incidence in Shenzhen City.

Objective To explore the role of chloride intracellular channel 5 (CLIC5) in the development of lung adenocarcinoma (LUAD). Methods The expression levels of CLIC5 in LUAD samples were determined using bioinformatics and qRT-PCR. The correlation between CLIC5 expression and LUAD progression was revealed through survival analysis and clinicopathological feature analysis. After the knockdown or overexpression of CLIC5 in the LUAD cells, cell proliferation was assessed through colony formation assay, cell apoptosis rate by flow cytometry, and cell migration and invasion by scratch and Transwell invasion assay. The protein levels of vimentin and Snail were detected by Western blot. Results Bioinformatics analysis results showed low CLIC5 expression levels in the LUAD samples. This finding was associated with the aggressive progression of LUAD and the poor survival of patients with LUAD. The qRT-PCR results confirmed that CLIC5 was mainly expressed in the cytoplasm of the LUAD cells. CLIC5 overexpression inhibited cell activity and proliferation and promoted the apoptosis of LUAD cells. The knockdown of CLIC5 exhibited the opposite effect. CLIC5 overexpression inhibited the migration and invasion of LUAD cells, downregulated Bcl-2, vimentin, and Snail and upregulated Bax, cleaved caspase-3 and E-cadherin in the LUAD cells. CLIC5 knockdown exhibited opposite effects. Conclusion CLIC5 overexpression promotes cell apoptosis and inhibits cell proliferation and invasion, thereby inhibiting the development of LUAD. Hence, CLIC5 is a novel biomarker of prognosis and therapeutic target for LUAD.

[Objective] To investigate the infection status and characteristics of HEV among voluntary blood donors in Ningbo, and to provide a basis for improving the blood screening strategy. [Methods] A total of 12 227 blood samples from voluntary blood donors in Ningbo from June 2022 to May 2023 were tested for HEV serology, enzymology, and nucleic acid testing. Furthermore, HEV gene sequencing was performed for genotyping analysis, and donors with reactive nucleic acid testing results were followed up to confirm their infection status. [Results] The reactivity rate of HEV Ag, anti-HEV IgM and anti-HEV IgG was 0.098%, 0.899% and 29.198%, respectively. There was no difference in the reactivity of anti-HEV IgM and anti-HEV IgG between genders, donation frequencies and donation types (P>0.05). The reactivity rate increased significantly with age (P<0.05). The rate of ALT disqualification (ALT>50U/L) was significantly higher than that in non-reactive samples (P<0.05). The HEV Ag reactivity rate (0.098%) was not correlated with gender, donation frequency, donation type or age. One HEV RNA positive case was found, with a positive rate of 0.008%(1/12 227). It was confirmed to be hepatitis E virus genotype 3 by sequencing analysis. Apart from HEV Ag reactivity, all other blood safety screening items were non-reactive, suggesting this case might be in the acute infection phase. The follow-up results showed that all indicators of the donor's previous blood donation were non-reactive. [Conclusion] Pre-donation ALT detection can reduce the risk of transfusion-transmitted HEV (TT-HEV) to a certain extent, and the effective way to prevent TT-HEV is to detect HEV RNA and serology of donor blood.

Endoscopic thoracic sympathicotomy/sympathotomy (ETS) is the first-line treatment for palmar hyperhidrosis with best minimally invasive effect. In recent years, with the widespread development of ETS in the treatment of palmar hyperhidrosis, many medical centers list ETS surgery as the day surgery. Nevertheless, there is no expert consensus on medical quality control of day surgery for ETS yet. Therefore, the Chinese Medical Doctor Association Thoracic Surgeons Branch Hyperhidrosis Subcommittee, Sympathetic Neurosurgery Expert Committee of WU Jieping Medical Foundation, and Fujian Provincial Strait Medical and Health Exchange Association Hyperhidrosis Special Committee organized domestic experts to conduct repeated consultations and sufficient discussions based on domestic and foreign literatures, to formulate the "Chinese expert consensus on ETS optimization and surgical quality control of day surgery for palmar hyperhidrosis". It aims to provide a reference for the clinical diagnosis and treatment of palmar hyperhidrosis for thoracic surgery colleagues in our country, to enhance their management level and work efficiency, and ultimately to achieve standardized quality control.

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common digestive system disease with high prevalence and recurrence rates for years, high treatment costs, and serious impacts on patients' quality of life and economic burden. Therefore, it is important to explore new and safe treatment methods. The pathogenesis of IBS-D is complex, in which the gut-brain axis is a key factor. The gut-brain axis, a bidirectional signaling pathway connecting the gastrointestinal tract and the central nervous system, regulates gastrointestinal motility, secretion, and immune responses, playing a key role in the occurrence and development of IBS-D. Up to now, antidiarrheal agents, probiotics, and neurotransmitter modulators are the main methods for the clinical treatment of IBS-D. Although they can partially curb the progression of this disease, the therapeutic effects remain to be improved. Studies have confirmed that traditional Chinese medicine (TCM) has significant advantages in the treatment of IBS-D since it can regulate the gut-brain axis via multiple pathways and targets to improve the gastrointestinal motility and strengthen immune defenses. However, there is a lack of systematic reviews on the regulation of the gut-brain axis by TCM in the treatment of IBS-D. Based on the review of IBS-D-related articles published in recent years, this paper systematically summarized the relationship between the gut-brain axis and IBS-D and the role of TCM in the treatment, providing new ideas for the treatment of IBS-D.

BackgroundAtypical antipsychotics have been widely used in patients with chronic schizophrenia, and aripiprazole and risperidone are the most commonly used drugs. The mechanism of action of the two is different, while previous studies have provided insufficient credible evidence from multiple perspectives to support the comparative efficacy of the two drugs in improving symptoms in patients with chronic schizophrenia. ObjectiveTo compare the efficacy of aripiprazole and risperidone on the improvement of symptoms, prepulse inhibition (PPI), cognitive functioning and neurotrophic factors in patients with chronic schizophrenia, so as to provide effective treatment regimens for these patients. MethodsA total of 86 patients with chronic schizophrenia attending the psychiatry department of the Third People's Hospital of Fuyang from March 2021 to March 2023 and fulfilling the diagnostic criteria of International Classification of Diseases, tenth edition (ICD-10) were enrolled and grouped using random number table method, each with 43 cases. Aripiprazole group was given oral aripiprazole once daily at an initial dose of 5 mg for one week and then gradually increased to a maximum dose of 25 mg. Risperidone group received oral risperidone twice daily at an initial dose of 0.5 mg for one week and then gradually increased to a maximum dose of 3 mg. Treatment in both groups lasted 3 months. Before treatment and 3 months after treatment, Patients were required to complete Positive and Negative Symptom Scale (PANSS), detection of both strong and weak PPIs in a startle modification passive attention paradigm, Wisconsin Card Sorting Test (WCST) and the measurement of neurotrophic factors at baseline and after treatment. The adverse reactions were recorded. Analysis of covariance was used to test the difference between the PANSS score, PPI, WCST and neurotrophic factor levels of the groups, with the pretest used as the covariate. Results3 months after treatment, no statistical difference was found in the scores of PANSS general psychopathology subscale, positive symptom subscale, negative symptom subscale and total score between two groups after treatment (F=0.621, 0.815, 0.743, 0.752, P>0.05). There were no statistically significant differences between the two groups in PPI inhibition rate, single intense stimulus amplitude, single intense stimulus latency, prepulse inhibition amplitude, or prepulse inhibition latency (F=0.174, 0.001, 0.183, 0.171, 0.001, P>0.05). There was no statistically significant difference in the total number of WCST tests between two groups (F=0.512, P>0.05), whereas aripiprazole group reported significantly larger total numbers of categories completed and correct responses as well as smaller total numbers of random errors and perseverative errors compared to risperidone group (F=3.737, 4.621, 4.892, 5.130, P<0.05). A significant increase in brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) along with a reduction in glial fibrillary acidic protein (GFAP) were documented in risperidone group when compared to risperidone group (F=4.414, 3.781, 6.319, P<0.05). No significant difference was demonstrated in the incidence of adverse reactions between the two groups (χ2=0.261, P>0.05). ConclusionAripiprazole may be more beneficial than risperidone in improving cognitive functioning and neurotrophic factor levels in patients with chronic schizophrenia.

OBJECTIVES:
To analyze the differential expression and biological functions of circRNAs in the anterior lens capsules of high myopic patients with cataract and their pathogenic roles in the development of this condition.
METHODS:
Anterior lens capsule specimens were collected intraoperatively from 36 patients with age-related cataract (ARC) and 36 high myopic patients with cataract. Among these, 18 specimens from each group were selected for whole transcriptome sequencing and biological analysis, and the remaining 36 specimens were used for validation of circPDGFRA, circFOXJ3, hsa_circ_0004767, hsa_circ_0007528, ciCRIM1, circMAN1A2, circSLC5A3, and circPTK2 expressions using RT-qPCR. hsa_circ_0007528 was selected for cell experiments to examine its effects on proliferation, migration, and apoptosis of lens epithelial cells (LECs).
RESULTS:
A total of 16 192 circRNAs were detected in the specimens from both groups, among which 62 circRNAs were differentially expressed (29 upregulated and 33 downregulated). GO and KEGG analyses revealed that the differentially expressed circRNAs were primarily localized in the cytoplasm, nucleoplasm, and endoplasmic reticulum, and were involved in signaling pathways associated with Gap junction and the PI3K-Akt, NF-κB, Jak-STAT, HIF-1, and MAPK signaling pathways. The ceRNA network predicted multiple target genes. RT-qPCR validation results were consistent with the sequencing data. In the LECs, upregulation of hsa_circ_0007528 significantly inhibited cell proliferation and migration and obviously promoted cell apoptosis.
CONCLUSIONS
The expression profile of circRNAs in the anterior lens capsule of high myopic patients with cataract differs from that of ARC patients. Upregulation of hsa_circ_0007528 inhibits LEC proliferation and migration and promotes cell apoptosis.
