On June 16, 2023, National Disease Control and Prevention Administration of the People’s Republic of China, in collaboration with other ministries, formulated and issued the Action Plan to Accelerate the Elimination of Schistosomiasis in China (2023—2030). The implementation of this plan provides an important basis for achieving the targets set in the “Healthy China 2030” action plan and the implementation of the rural revitalization strategy. This paper describes the background, principles, targets, control strategies, safeguard measures and effectiveness evaluation of the plan, in order to guide the scientific and standardized implementation of actions for schistosomiasis elimination at the grassroots level, and facilitate the progress towards elimination of schistosomiasis in China with a high quality.

Objective:To investigate the correlation factors of complete clinical response in idiopathic inflammatory myopathies(IIMs)patients receiving conventional treatment.Methods:Patients diagnosed with IIMs hospitalized in Peking University People's Hospital from January 2000 to June 2023 were in-cluded.The correlation factors of complete clinical response to conventional treatment were identified by analyzing the clinical characteristics,laboratory features,peripheral blood lymphocytes,immunological indicators,and therapeutic drugs.Results:Among the 635 patients included,518 patients finished the follow-up,with an average time of 36.8 months.The total complete clinical response rate of IIMs was 50.0％(259/518).The complete clinical response rate of dermatomyositis(DM),anti-synthetase syn-drome(ASS)and immune-mediated necrotizing myopathy(IMNM)were 53.5％,48.9％and 39.0％,respectively.Fever(P=0.002)and rapid progressive interstitial lung disease(RP-ILD)(P=0.014)were observed much more frequently in non-complete clinical response group than in complete clinical re-sponse group.The aspartate transaminase(AST),lactate dehydrogenase(LDH),D-dimer,erythrocyte sedimentation rate(ESR),C-reaction protein(CRP)and serum ferritin were significantly higher in non-complete clinical response group as compared with complete clinical response group.As for the treat-ment,the percentage of glucocorticoid received and intravenous immunoglobin(IVIG)were significantly higher in non-complete clinical response group than in complete clinical response group.Risk factor analysis showed that IMNM subtype(P=0.007),interstitial lung disease(ILD)(P=0.001),eleva-ted AST(P=0.012),elevated serum ferritin(P=0.016)and decreased count of CD4+T cells in peripheral blood(P=0.004)might be the risk factors for IIMs non-complete clinical response.Conclu-sion:The total complete clinical response rate of IIMs is low,especially for IMNM subtype.More effec-tive intervention should be administered to patients with ILD,elevated AST,elevated serum ferritin or decreased count of CD4+T cells at disease onset.

Objective To explore the causal relationship between sleep phenotype and idiopathic normal pressure hydrocephalus(iNPH)using two-sample bidirectional Mendelian randomization.Methods The exposure data including 8 sleep phenotypes used in this study were obtained from GWAS catalog,FinnGenR10 and MRCIEU GWAS.The outcome data for idiopathic normal-pressure hydrocephalus were obtained from FinnGen R10.We used the inverse-variance weighted(IVW)method to perform the principal analyses.Cochrane Q-statistics test was used to assess the heterogeneity and MR Egger-intercept test performed to evaluate the pleiotropy for sensitivity analyses.Results IVW result showed that frequent daytime nap was associated with higher odds of iNPH(OR=3.3393,95 CI%:1.0646-10.4742,P=0.0270).Cochrane Q-statistics test and MR Egger-intercept test showed that the MR analysis had no pleiotropy or heterogeneity(P>0.05).The external validation reproduced this result(OR=2.5660,95 CI%:1.1680-5.6373,P=0.0189;OR=4.0424,95 CI%:1.5709-10.4024,P=0.0038).Reverse Mendelian randomization suggested that iNPH did not have significant impact on sleep phenotype.Conclusion The frequency of daytime naps is causally associated with iNPH,and reducing the frequency of weekly daytime naps can reduce the risk of iNPH in the elderly population.

Objective To evaluate the molluscicidal effect of spraying different formulations of niclosamide ethanolamine salt with drones against Oncomelania hupensis in ditches. Methods A semi-dry and semi-wet ditch with O. hupensis snails was selected in the second branch field of Jiangbei Farm, Jiangling County, Hubei Province in May 2023, and divided into 4 experimental areas, named groups A1, A2, B1 and B2. Environmental cleaning was performed in groups A1 and B2, and was not conducted in groups A2 or B2. Then, 50% wettable powder of niclosamide ethanolamine salt was sprayed with drones at an effective dose of 2 g/m² in groups A1 and A2, and 5% niclosamide ethanolamine salt granule was sprayed with drones at an effective dose of 2 g/m² in groups B1 and B2. O. hupensis snails were surveyed using the systematic sampling method 1, 3, 5, 7, 14 days after spraying, and the natural mortality and corrected mortality of O. hupensis snails were calculated. Results The occurrence of frames with living snails, mean density of living snails and natural mortality of snails were 97.50% (117/120), 6.30 snails/0.1 m² and 1.18% (9/765) in the test ditch before spraying, respectively. There were significant differences in the mortality of snails among four groups 1, 3, 5, 7 and 14 days after spraying niclosamide formulations with drones (χ² = 17.230, 51.707, 65.184, 204.050 and 34.435, all P values < 0.01). The overall mortality rates of snails were 94.51% (1 051/1 112), 79.44% (908/1 143), 96.54% (977/1 012) and 88.55% (1 021/1 153) in groups A1, A2, B1 and B2 (χ² = 207.773, P < 0.05), respectively. In addition, there was no significant difference in the overall snail mortality between groups A1 and B1 (P > 0.05), and the snail mortality in groups A1 and B1 were both statistically different from that in groups A2 and B2 (all P values < 0.05). Conclusion Both 50% wettlable powder of niclosamide ethanolamine salt and 5% niclosamide ethanolamine salt granule sprayed with drones are active against O. hupensis snails in ditches, and environmental cleaning may improve the molluscicidal effect.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:To investigate the protective effect of berberine hydrochloride on intestinal mucosal barrier damage in sepsis rats and its mechanism.Methods:Forty-eight male SD rats were divided into a control group (Sham group, 6 cases), a sepsis model group (LPS group, 14 cases), a berberine hydrochloride intervention group (Ber group, 14 cases), and a Notch signaling pathway inhibition group (DAPT group, 14 cases) according to random number table method. The DAPT group was intraperitoneally injected with 5 mg/kg Notch signaling pathway inhibition DAPT 2 hours before modeling. The sepsis model was established by intraperitoneal injection of 10 mg/kg lipopolysaccharide (LPS); Sham group was injected with an equal amount of saline (2 mL). The Ber group and DAPT group were treated with gavage of 50 mg/kg berberine hydrochloride 2 hours after modeling; Sham group and LPS group were treated with gavage of an equal amount of saline (2 mL). The temperature, weight, behavior and survival rate of rats were observed at 0, 6, 12 and 24 hours of modeling. After 24 hours of modeling, abdominal aortic blood was collected under anesthesia, and intestinal tissues were obtained after euthanasia. The pathological changes of ileum were observed under light microscope. The ultrastructure of ileum was observed under transmission electron microscope. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of serum diamine oxidase (DAO), intestinal fatty acid binding protein (iFABP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6). Real time-polymerase chain reaction (RT-PCR) and Western blotting were used to detect the mRNA and protein expressions of tight junction proteins (Occludin and Claudin1), Notch1 and their downstream target signals in the ileum tissue.Results:After 24 hours of modeling, compared with the Sham group, the LPS group, Ber group, and DAPT group showed a decrease in weight and an increase in temperature. Among them, the LPS group showed the most significant changes, followed by the DAPT group, and the Ber group showed the least significant changes. The survival rates of the LPS group, Ber group, and DAPT group were all lower than those of the Sham group [42.9% (6/14), 57.1% (8/14), 57.1% (8/14) vs. 100% (6/6)], and six rats were taken from each group for subsequent testing. Macroscopic observation of the intestine showed that the LPS group had the most severe edema in the ileum tissue and abdominal bleeding, with significant improvement in the Ber group and followed by the DAPT group. Under the light microscope, the LPS group showed disordered arrangement of glandular tissue in the ileum mucosa, significantly reduced goblet cells, and extensive infiltration of inflammatory cells, which were significantly improved in the Ber group but less improved in the DAPT group. Under electron microscopy, the LPS group showed extensive shedding of ileal microvilli and severe damage to the tight junction complex structure of intestinal epithelial cells, which was significantly improved in the Ber group but less improved in the DAPT group. The levels of serum DAO, iFABP, TNF-α, IL-6 in the LPS group were significantly higher than those in the Sham group, while the above indicators in the Ber group were significantly lower than those in the LPS group [DAO (μg/L): 4.94±0.44 vs. 6.53±0.49, iFABP (ng/L): 709.67±176.97 vs. 1 417.71±431.44, TNF-α (ng/L): 74.70±8.15 vs. 110.36±3.51, IL-6 (ng/L): 77.34±9.80 vs. 101.65±6.92, all P < 0.01], while the above indicators in the DAPT group were significantly higher than those in the Ber group. The results of RT-PCR and Western blotting showed that the mRNA and protein expressions of Occludin, Claudin1, Notch1, and Hes1 in the ileum tissue of LPS group rats were decreased compared to the Sham group, which were significantly increased in the Ber group compared with the LPS group [mRNA expression: Occludin mRNA (2 -ΔΔCt): 1.61±0.74 vs. 0.30±0.12, Claudin1 mRNA (2 -ΔΔCt): 1.97±0.37 vs. 0.58±0.14, Notch1 mRNA (2 -ΔΔCt): 1.29±0.29 vs. 0.36±0.10, Hes1 mRNA (2 -ΔΔCt): 1.22±0.39 vs. 0.27±0.04; protein expression: Occludin/GAPDH: 1.17±0.14 vs. 0.74±0.04, Claudin1/GAPDH: 1.14±0.06 vs. 0.58±0.10, Notch1/GAPDH: 0.87±0.11 vs. 0.56±0.09, Hes1/GAPDH: 1.02±0.13 vs. 0.62±0.01; all P < 0.05], while those in the DAPT group were significantly lower than those in the Ber group. Conclusion:Early use of berberine hydrochloride can significantly improve intestinal mucosal barrier damage in sepsis rats, and its mechanism may be related to inhibiting inflammatory response and regulating the expression of intestinal mechanical barrier tight junction protein through Notch1 signal.

Objection:To evaluate the effects of the miniscrew supported removable palatal arch for maxillary molar distalization.Methods:33 patients with mild to moderate crowding teeth and maxillary protrusion were treated with the miniscrew supported remova-ble palatal arch.The lateral cephalograms and dental plaster models were taken at the beginning of the treatment(T0)and at the end of molar distalization(T1).The multicentre variables were measured and compared with statistical software.Results:Cephalometrics showed that the average distance(mm)of the firs molar distalization was 3.6(P＜0.001),molar distal tipping was 6°(P＜0.001)and molar intrusion(mm)was 0.6(P＜0.05).The measurements of right and left molar distalization on plaster models were 4.2 mm(P＜0.001)and 4.0 mm(P＜0.001)respectively,the width of dental arch was increased by 3.1 mm(P＜0.05).The data of distalization of the first molar showed no statistical difference between right and left side on plaster cast and between model and cephalometric meas-urements.On the right side the angle between the mesial-distal tips line and the middle line was increased by 1.6°(P＞0.05),on the left by 4.8°(P＜0.05).Conclusion:The none extraction therapy for mild to moderate crowding teeth and maxillary protrusion can be realized by miniscrew supported removable palatal arch distalization appliance.

Purpose: The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored. Materials and Methods: On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL). Results: A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse. Conclusion This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).

Standardization is the universal language of the world, and standardization of traditional Chinese medicine (TCM) is essential for its communication in China and globally. However, the principles and methods of TCM acupuncture standardization have been unclear and inadequate in the early stages. Based on an investigative approach to understanding the current status, identifying problems, and finding solutions, our team has established basic principles of TCM acupuncture that embody Chinese wisdom, evaluated the international strategic environment systematically, proposed the principle of “importance of harmony and exercise of impartiality”, and established basic working principles. A series of methods for TCM acupuncture standard development and evaluation have been constructed, including general standards for the revision of TCM acupuncture standards, the first TCM acupuncture clinical research management specification, a shared full chain technology platform, a data center, and an evaluation research base for TCM acupuncture clinical research. Evaluation criteria for ancient literature and expert experience, a recommendation method for the “three main and three auxiliaries” TCM guideline for prevention were established, and quantifiable assessment methods of TCM standard applicability were proposed. These findings provide methodological guidance for TCM acupuncture standardization.
