Objective To investigate the effectiveness of the integrated schistosomiasis control programme in Sichuan Province during the stage moving from transmission interruption to elimination (2015—2023), so as to provide insights into formulation of the schistosomiasis control measures during the post-elimination stage. Methods Schistosomiasis control data were retrospectively collected from departments of health, agriculture and rural affairs, forestry and grassland, water resources, and natural resources in Sichuan Province from 2015 to 2023, and a database was created to document examinations and treatments of human and livestock schistosomiasis, and snail survey and control, conversion of paddy fields to dry fields, ditch hardening, rivers and lakes management and building of forests for snail control and schistosomiasis prevention. The completion of schistosomiasis control measures was investigated, and the effectiveness was evaluated. Results A total of 20 545 155 person-times received human schistosomiasis examinations in Sichuan Province during the period from 2015 to 2023, and 232 157 person-times were seropositive, with a reduction in the seroprevalence from 2.10% (44 299/2 107 003) in 2015 to 1.12% (9 361/837 896) in 2023 (χ² = 7.68, P < 0.001). The seroprevalence of human schistosomiasis appeared a tendency towards a decline in Sichuan Province over years from 2015 to 2023 (b = −8.375, t = −10.052, P < 0.001); however, no egg positive individuals were identified during the period from 2018 to 2023, with the prevalence of human Schistosoma japonicum infections maintained at 0. Expanded chemotherapy was administered to 2 754 515 person-times, and medical assistance of advanced schistosomiasis was given to 6 436 persontimes, with the treatment coverage increasing from 46.80% (827/1 767) in 2015 to 64.87% (868/1 338) in 2023. Parasitological tests for livestock schistosomiasis were performed in 35 113 herd-times, and expanded chemotherapy was administered to 513 043 herd-times, while the number of fenced livestock decreased from 121 631 in 2015 to 103 489 in 2023, with a reduction of 14.92%. Snail survey covered 433 621.80 hm² in Sichuan Province from 2015 to 2023, with 204 602.81 hm² treated by chemical control and 4 637.74 hm² by environmental modifications. The area of snail habitats decreased from the peak of 5 029.80 hm² in 2016 to 3 709.72 hm² in 2023, and the actual area of snail habitats decreased from the peak of 8 585.48 hm² in 2016 to 473.09 hm² in 2023. The mean density of living snails remained low across the study period except in 2017 (0.62 snails/0.1 m²). Schistosomiasis control efforts by departments of agriculture and rural affairs in Sichuan Province included conversion of paddy fields to dry fields covering 153 346.93 hm², hardening of 6 110.31 km ditches, building of 70 356 biogas digesters, replacement of cattle with 227 161 sets of machines, and captive breeding of 21 161 070 livestock from 2015 to 2023, and the control efforts by departments of water resources included rivers and lakes management measuring 5 676.92 km and renovation of 2 331 irrigation areas, while the control efforts by departments of forestry and grassland included building of forests for snail control and schistosomiasis prevention covering 23 913.33 hm², renovation of snail control forests covering 8 720 hm² and newly building of shelterbelts covering 764 686.67 hm². All 63 endemic counties (cities and districts) had achieved the criterion for schistosomiasis elimination criteria in Sichuan Province by the end of 2023. Conclusion Following the integrated control efforts from 2015 to 2023, remarkable achievements have been obtained in the schistosomiasis control programme in Sichuan Province, with all endemic counties successfully attaining the schistosomiasis elimination target at the county level.

Objective:To explore the factors affecting changes of disc angle (ΔDA) during oblique lateral interbody fusion (OLIF) and establish a predictive model of ΔDA.Methods:This retrospective study included 119 patients with 174 segments undergoing OLIF procedures between July 2017 and August 2019 in Beijing Jishuitan Hospital. 45 males and 74 females with an average age of 62.1±9.8 years (33-86 years) were included. The lordotic cages were all 6 degrees. Radiographic parameters included preoperative and postoperative disc angle (DA), disc height (DH), ΔDA on flexion-extension views (ΔDA-FE), cage location and cage inclination. Pearson correlation coefficient and machine-learning techniques were utilized to identify factors related to ΔDA. Based on machine leaning techniques, ten-fold cross-validation for model training and validation were used to develop a predictive linear model for ΔDA.Results:The average ΔDA was 3.9°±4.8° with preoperative disc angle (preoperative DA) of 5.3°±5.0°. The average change of posterior DH (ΔPDH) was 3.1±2.1 mm with preoperative posterior DH of 6.6±1.9 mm. The average change of anterior DH was 6.1±3.2 mm. Pearson correlation analysis showed a significant negative correlation between ΔDA and preoperative DA ( r=-0.713, P<0.001), cage location ( r=-0.183, P=0.016), and ΔDA-FE ( r=-0.153, P=0.044). PDH changes were significantly negatively correlated with preoperative PDH ( r=-0.444, P<0.001) and positively correlated with cage location ( r=0.218, P=0.004). ΔDA was 10.8°±3.2° for negative preoperative DA (indicating kyphotic), 5.0°±3.7° for preoperative DA between 0° and 6°, and 1.0°±4.1° for preoperative DA>6°. A predictive model was developed using ten-fold cross-validation, resulting in the formula ΔDA=7.9°-0.8×preoperative DA ( R=0.707, MAE=2.837). Conclusion:Disc angle changes in OLIF primarily depend on the preoperative disc angle, secondly on cage location. The predicting model based on machine-learning techniques using preoperative disc angle facilitates preoperative planning for OLIF procedures.

Post-traumatic stress disorder (PTSD),with the principal manifestations as invasive thinking,avoidance,negative emotions and cognition,and increased alertness,is a psychological disorder occurring after traumatic events. Sleep disorders are also considered as one of the core characteristics of PTSD. Previous studies have partly revealed the relationship between PTSD and sleep disorders,but the physiological mechanism of the relationship is still unclear. This article provides an overview of the clinical and physiological characteristics of PTSD and sleep disorders. Based on this,the bidirectional relationship between PTSD and sleep disorders is discussed,and the relevant physiological and brain mechanisms of the relationship between them are further explored. Future research needs to explore the neurophysiological mechanisms underlying the bidirectional relationship between PTSD and sleep by exploring the brain regions and neural circuits associated with both PTSD and sleep,providing more information and methods for the prevention and treatment of PTSD and sleep disorders.

Objective To compare the clinical outcomes between oblique lumbar interbody fusion(OLIF)and transforaminal lumbar interbody fusion(TLIF)for patients with degenerative spondylolisthesis during 2-year follow-ups.Methods Patients with symptomatic degenerative spondylolisthesis who underwent OLIF(46 cases)and TLIF(45 cases)between July 2017 and September 2020 with 2-year follow-ups were retrospectively reviewed.One level or two-level lumbar fusion were included.The primary outcomes were Visual Analogue Scale(VAS)and Oswestry Disability Index(ODI)at 2 years after surgery.The secondary outcomes included radiographic parameters,fusion rate,cage subsidence rate,and permanent nerve injury rate.Results No significantly different changes were noted in VAS-back[2(2,3)vs.2(2,2),P=0.943],VAS-leg[2(2,2)vs.2(2,2),P=0.988],and ODI[17％(10％,22％)vs.14％(10％,22％),P=0.417]between the OLIF group and the TLIF group,respectively.Greater restoration of disc height and segmental lordosis were obtained in the OLIF group[mean,(11.9±1.5)mm and 15.7°±7.2°]than in the TLIF group[mean,(9.2±2.0)mm and 12.5°±5.9°]at postoperative 2-year(P＜0.001 and P=0.029).The subsidence rate was lower in the OLIF group than in the TLIF group[19.6％(9/46)vs.40.0％(16/40),P=0.037].The fusion rates at postoperative 2-year were 93.5％(43/46)in the OLIF group and 87.5％(35/40)in the TLIF group,having no significant difference(P=0.562).The rates of permanent nerve injury were similar between the two groups[4.3％(2/46)vs.6.7％(3/45),P=0.980]at postoperative 2-year.Conclusion Short segment OLIF doesn't show better clinical outcomes and fusion rate than TLIF for degenerative spondylolisthesis,except for greater disc height restoration,greater segmental lordosis,and lower subsidence rate at postoperative 2-year.

An ambitious goal has been set for elimination of schistosomiasis in all endemic counties (districts) in Sichuan Province by 2023. To achieve this goal, and to continue to consolidate the control achievements, it is necessary to understand the current endemic status of schistosomiasis, identify the challenges and analyze the experiences and lessons from the schistosomiasis control program, and develop targeted control strategies and interventions in the province. This paper reviews the progress of schistosomiasis control in Sichuan Province since the 12th Five-Year Plan period, analyzes the challenges in the schistosomiasis elimination program, and proposes recommendations for future directions and priorities.

Objective:To evaluate the effect of oblique lateral interbody fusion (OLIF) combined with posterior fixation on segmental alignment in the treatment of degenerative spondylolisthesis (DS).Methods:The clinical data of 40 patients with DS who underwent OLIF combined with posterior fixation from July 2017 to December 2019 were retrospectively analyzed. There were 7 males and 33 females, aged 45-81 years, with an average age of 65.7±9.06 years. The total number of slip segments was 43, including 37 levels at L 4, 5, 5 levels at L 3, 4, and 1 level at L 2, 3. According to the decompression methods, the patients were divided into two groups. 22 patients with 23 levels were treated with direct decompression combined with laminectomy, and 18 patients with 20 levels were treated with indirect decompression without laminectomy. All patients underwent preoperative and intraoperative imaging examination. The disc height (DH), slip ratio (SR) and segmental lordosis (SL) were measured by preoperative CT and intraoperative fluoroscopy images. One-way repeated measures ANOVA was used to compare the radiographic parameters of the segmental alignment prior to cage implantation, following cage insertion and posterior fixation. Bonferroni test was used to compare the radiographic parameters between groups. Results:In the OLIF combined with the posterior fixation, there were statistically significant differences in the radiographic parameters of segmental alignment at different stages of operation [DH ( F=147.786, P<0.001) , SR ( F=83.754, P<0.001) , SL ( F=38.296, P<0.001) ]. DH increased from 7.99±1.39 mm to 11.69±1.72 mm ( P<0.001), SR decreased from 10.67%±4.67% to 8.66%±4.50% ( P=0.001) and SL increased from 7.26°±2.73° to 7.85°±2.30° ( P=0.425). After combined posterior fixation, SR further decreased from 8.66%±4.50% to 2.07%±4.00% ( P<0.001), SL further increased from 7.85°±2.30° to 10.72°±3.08° ( P<0.001), and DH had no significant change ( P=1.000). There was no significant difference in radiographic parameters between the direct decompression group and the indirect decompression group when prior to cage implantation, following cage insertion and following posterior fixation, respectively. Conclusion:OLIF combined with posterior fixation in the treatment of DS can further reduce the slip rate of patients with lumbar degenerative spondylolisthesis and increase the lordosis angle of the surgical segment. At the same time, the direct decompression combined with laminectomy has no significant effect on the segmental alignment.

Objective:To explore the genetic characteristics, clinical features, and prognostic values of RAS mutations in patients with myelofibrosis (MF) .Methods:We analyzed 112-gene targeted sequencing data from 226 patients who had a diagnosis of either primary myelofibrosis (PMF) or post-polycythemia vera/post-essential thrombocythemia (post-PV MF and post-ET MF) from December 2011 to December 2019. A retrospective analysis of the genetic characteristics, clinical features, and prognosis of RAS mutations was performed.Results:Among 266 patients diagnosed PMF or post-PV/ET MF, RAS mutations were found in 14 (6.2%) cases, including 9 (4.0%) cases of NRAS mutations, 8 (3.5%) cases of KRAS mutations, and 3 (1.3%) cases of both NRAS and KRAS mutations. All of the NRAS mutations were located in codons 12 and 13. The median VAFs of RAS mutations were significantly lower than those of the driver mutations, confirming that they represent sub-clonal events that are acquired during the disease course. SETBP1, SRSF2, and MPL tended to be clustered with RAS mutations. Patients with RAS mutations had a higher number of additional oncogenic mutations (median, 3.36 vs 1.17, P<0.001) . RAS mutations had a statistically significant association with elevated monocyte cell counts ( P=0.003) , lower platelet counts ( P=0.026) , higher bone marrow blasts ( P=0.022) , splenomegaly ( P=0.005) , and very high-risk (VHR) karyotype abnormality percentage ( P=0.031) . In univariate analysis, the OS of patients with NRAS mutations were significantly inferior in the entire MF and PMF cohorts ( P=0.001, P=0.008) . In a multivariate model, NRAS retained an independent negative prognostic factor in PMF. Conclusion:RAS gene mutations were constantly related to elevated monocyte cell counts, lower platelet counts, higher bone marrow blasts, and VHR karyotype abnormality percentage that usually defined high-risk disease and often occurred as sub-clonal events. NRAS mutation is an independent poor prognostic factor in PMF.

Objective To evaluate the application value of the blastocysts derived from non-pronucleus (0PN) zygotes by the good quality blastocyst formation rate and the clinical outcomes of frozen-thawed blastocyst transfers. Methods The good quality blastocyst formation rate derived from 0PN zygotes was compared with that derived from2 pronucleus(2PN)zygotes in in vitro fertilization(IVF)or intracytoplasmic sperm injection (ICSI) cycles from January 2015 to December 2016. In addition, the clinical pregnancy, embryo implantation and live birth rates of frozen-thawed blastocyst transfers with blastocysts derived from 0PN and 2PN zygotes were analyzed on corresponding dates. Results (1)In IVF cycles, the high quality blastocysts formation rate of 2PN embryos was significantly higher than that of 0PN (46.64% versus 42.42%, P<0.01). In ICSI cycles, the high quality blastocysts formation rate of 2PN embryos was markedly higher than that of 0PN(41.96% versus 21.73%, P<0.01).(2)In frozen-thawed embryo transfer cycles for IVF, the clinical pregnancy, implantation and live birth rates of D5 0PN blastocysts were significantly higher than those of D6 2PN(52.64% versus 46.78%, 49.91% versus 41.20%, 46.54% versus 39.56%, all P<0.05), however, the abortion and newborn abnormal rates of D5 0PN blastocysts were lower than those of D6 2PN blastocysts(17.37% versus 23.36%, 1.31% versus 4.21%, both P<0.05); the clinical pregnancy, implantation and livebirth rates of D5 2PN blastocysts were significantly higher than those of D5 0PN(59.73% versus 52.64%, 55.95% versus 49.91%, 53.03% versus 46.54%, all P<0.05), but newborn abnormal rate was a little higher than that of D5 0PN(3.90% versus 1.31%, P<0.05);the clinical pregnancy, implantation and live birth rates of D5 2PN blastocysts were significantly higher than those of D6 2PN(59.73% versus 46.78%, 55.95% versus 41.20%, 53.03% versus 39.56%, all P<0.05), and the abortion rate of D5 2PN blastocysts was lower than that of D6 2PN blastocysts(18.23% versus 23.36%, P<0.05). Conclusions Although the blastocysts derived from 0PN could be transffered, the blastocysts derived from 2PN zygotes are preferred in all cycles. In IVF cycles, the good quality blastocysts derived from 2PN or 0PN zygotes will be transferred.
