On February 2022, WHO released the evidence-based guideline on control and elimination of human schistosomiasis, with aims to guide the elimination of schistosomiasis as a public health problem in disease-endemic countries by 2030 and promote the interruption of schistosomiasis transmission across the world. Based on the One Health concept, six evidence-based recommendations were proposed in this guideline. This article aims to analyze the feasibility of key aspects of this guideline in Chinese national schistosomiasis control program and illustrate the significance to guide the future actions for Chinese national schistosomiasis control program. Currently, the One Health concept has been embodied in the Chinese national schistosomiasis control program. Based on this new WHO guideline, the following recommendations are proposed for the national schistosomiasis control program of China: (1) improving the systematic framework building, facilitating the agreement of the cross-sectoral consensus, and building a high-level leadership group; (2) optimizing the current human and livestock treatments in the national schistosomiasis control program of China; (3) developing highly sensitive and specific diagnostics and the framework for verifying elimination of schistosomiasis; (4) accelerating the progress towards elimination of schistosomiasis and other parasitic diseases through integrating the national control programs for other parasitic diseases.

Preventive chemotherapy is one of the pivotal interventions for the control and elimination of schistosomiasis, which is effective to reduce the morbidity and prevalence of schistosomiasis. In order to promote the United Nations' sustainable development goals and the targets set for schistosomiasis control in the Ending the neglect to attain the Sustainable Development Goals: a road map for neglected tropical diseases 2021-2030, WHO released the guideline on control and elimination of human schistosomiasis in 2022, with major evidence-based updates of the current preventive chemotherapy strategy for schistosomiasis. In China where great success has been achieved in schistosomiasis control, the preventive chemotherapy strategy for schistosomiasis has been updated several times during the past seven decades. This article reviews the evolution of the WHO guidelines on preventive chemotherapy and Chinese national preventive chemotherapy schemes, compares the current Chinese national preventive chemotherapy scheme and the recommendations for preventive chemotherapy proposed in the 2022 WHO guideline on control and elimination of human schistosomiasis, and proposes recommendations for preventive chemotherapy during the future implementation of the 2022 WHO guideline, so as to provide insights into schistosomiasis control among public health professionals engaging in healthcare foreign aid.

Objective: In order to assess ET more comprehensively, sonotubometry (STM)combined with CT images were applied to investigate the opening features of eustachian tube (ET) in normal subjects. STM was also used as a monitor training ET opening maneuver and optimizing CT scan parameters. Methods: Following ET opening training monitored by STM, STM data of ET opening duration and maximum sound pressure from 13 healthy volunteers (10 males and 3 females, 22 to 26 years old) were acquired using maneuvers of swallowing and Valsalva in standing and supine positions. Two trials of CT scan, setting A (slice thickness 6.0 mm, manually simulated to 0.6 mm, reconstruction thickness 0.6 mm) for normal and Valsalva scans and setting B(slice thickness 0.4 mm,reconstruction thickness 0.4 mm)for Valsalva scan, were conducted in each subject. The bone area and cartilage area of ET were measured respectively in reconstructed CT images. Statistical software SPSS 19.0 was employed in data analysis. Results: The duration of ET opening and maximum sound pressure by Valsalva were longer and stronger than those by swallowing in both positions. For Valsalva maneuver, standing position resulted in longer ET opening duration compared to supine position (P<0.05). Under setting A, ET cartilage area was measured larger by Valsalva scan than by normal scan (P<0.05). By Valsalva scan, setting A captured larger ET cartilage area compared to setting B (P<0.05). CT setting B resulted in longer scan time in comparison to setting A (P<0.05). Conclusions: Techniques of STM in supine position plus CT scan under setting A can be combined by Valsalva passive ET opening. Not only the invisible ET lumen through routine CT scan can be illustrated, but also relevant ET open-close process is shown, therefore, this study provides the technique for ET research of function and structure.

BACKGROUND: There were few studies on real-world data about autologous hematopoietic stem cell transplantation (auto-HSCT) or allogeneic HSCT (allo-HSCT) in peripheral T-cell lymphoma (PTCL). This study aimed to investigate the clinical outcomes of patients who received auto-HSCT or allo-HSCT in China. METHODS: From July 2007 to June 2017, a total of 128 patients who received auto-HSCT (n  = 72) or allo-HSCT (n  = 56) at eight medical centers across China were included in this study. We retrospectively collected their demographic and clinical data and compared the clinical outcomes between groups. RESULTS: Patients receiving allo-HSCT were more likely to be diagnosed with stage III or IV disease (95% vs. 82%, P = 0.027), bone marrow involvement (42% vs. 15%, P = 0.001), chemotherapy-resistant disease (41% vs. 8%, P = 0.001), and progression disease (32% vs. 4%, P < 0.001) at transplantation than those receiving auto-HSCT. With a median follow-up of 30 (2-143) months, 3-year overall survival (OS) and progression-free survival (PFS) in the auto-HSCT group were 70%(48/63) and 59%(42/63), respectively. Three-year OS and PFS for allo-HSCT recipients were 46%(27/54) and 44%(29/54), respectively. There was no difference in relapse rate (34%[17/63] in auto-HSCT vs. 29%[15/54] in allo-HSCT, P = 0.840). Three-year non-relapse mortality rate in auto-HSCT recipients was 6%(4/63) compared with 27%(14/54) for allo-HSCT recipients (P = 0.004). Subanalyses showed that patients with lower prognostic index scores for PTCL (PIT) who received auto-HSCT in an upfront setting had a better outcome than patients with higher PIT scores (3-year OS: 85% vs. 40%, P = 0.003). Patients with complete remission (CR) undergoing auto-HSCT had better survival (3-year OS: 88% vs. 48% in allo-HSCT, P = 0.008). For patients beyond CR, the outcome of patients who received allo-HSCT was similar to that in the atuo-HSCT group (3-year OS: 51% vs. 46%, P = 0.300). CONCLUSIONS Our study provided real-world data about auto-HSCT and allo-HSCT in China. Auto-HSCT seemed to be associated with better survival for patients in good condition (lower PIT score and/or better disease control). For patients possessing unfavorable characteristics, the survival of patients receiving allo-HSCT group was similar to that in the auto-HSCT group.

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

Objective: To explore the efficacy and prognostic factors of hematopoietic stem cell transplantation (HSCT) for the treatment of patients with anaplastic large cell lymphoma (ALCL) . Methods: The clinical records of 33 ALCL patients after HSCT were collected and analyzed retrospectively to evaluate the rates of overall survival (OS) and recurrence after autologous (auto-HSCT) and allogeneic HSCT (allo-HSCT) and the factors influencing prognosis. Results: The median-age of this cohort of 33 ALCL cases at diagnosis was 31 (12-57) years old with a male/female ratio of 23/10, 24 cases (72.7%) were ALK(+) and 9 ones (27.3%) ALK(-). Of them, 25 patients (19 ALK(+) and 6 ALK(-)) underwent auto-HSCT and 8 cases (5 ALK(+) and 3ALK(-)) allo-HSCT with a median follow-up of 18.7 (4.0-150.0) months. Disease states before HSCT were as follows: only 6 patients achieved CR status and received auto-HSCT, 16 patients achieved PR (14 cases by auto-HSCT and 2 ones allo-HSCT) , the rest 11 cases were refractory/relapse (5 cases by auto-HSCT and 6 ones allo-HSCT) . There were 7 cases died of disease progression (5 after auto-HSCT and 2 allo-HSCT) and 5 cases treatment-related mortality (TRM) (2 after auto-HSCT and 3 allo-HSCT) , TRM of two groups were 8.0% and 37.5%, respectively. Both the median progression-free survival (PFS) and OS were 15 months after auto-HSCT, the median PFS and OS after allo-HSCT were 3.7 (1.0-90.0) and 4.6 (1.0-90.0) months, respectively. There was no statistically significant difference in terms of survival curves between the two groups (OS and PFS, P=0.247 and P=0.317) . The 2-year OS rates in auto-HSCT and allo-HSCT groups were 72% and 50%, respectively. The 5-year OS rates in auto-HSCT and allo-HSCT groups were 36% and 25%, respectively. Conclusion: ALCL treated by chemotherapy produced high rates of overall and complete responses. Chemotherapy followed by auto-HSCT remained to be good choice for patients with poor prognostic factors. High-risk patients should be considered more beneficial from allo-HSCT.
