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 investigate the effect of hemoglobin A1c variability on the incidence of malignant tumors in type 2 diabetes mellitus (T2DM) patients, and to provide a reference for the prevention and treatment of diabetes. Methods A retrospective cohort study was used to integrate Shanghai malignant tumor registration information and T2DM patient management information of Minhang Districts in Shanghai. A record linkage was carried out using ID numbers for patients who had been diagnosed through the Cancer Registry System. Average Real Variability(ARV)was used to assess the variability for hemoglobin A1c results, with no less than 3 measurements and no more than 1 follow-up visit per year. Cox proportional hazards regression models and Restricted Cubic Splines (RCS) were used for statistical analysis. ARV was grouped using quartile classification, represented by Q1, Q2, Q3, and Q4, respectively. Cox regression was performed using unadjusted model I and model II adjusted for gender, age, and group. Results A total of 2 762 research subjects were included in the present study, with 45.84% males and 54.16% females. The average age was (63.58±10.11) years, and an average follow-up time was (9.96±3.66) years. Malignant tumor incidence rate was 345.45/100 000 person years. There was statistical significance among different ARV groups (P=0.01). COX regression analysis of model I and model II showed that compared with Q1, the risk of Q4 group was significantly increased, with HRs of 2.72 (1.56-4.74) and 2.68 (1.53-4.68), respectively. The RCS graph's analysis showed that except for the ≥65-year-old group, the risk of tumor incidence gradually increased with the increase of ARV coefficient. Conclusion The variability of hemoglobin A1c is positively associated with the risk of occurrence of malignant tumors in type 2 diabetes patients. It is necessary to strengthen the monitoring of hemoglobin A1c and to reduce the health hazards caused by fluctuations in hemoglobin A1c.

To investigate the detection status of human papillomavirus (HPV) among adult women in high-altitude regions of Xizang. A retrospective analysis was conducted on HPV genotyping results from outpatient, inpatient, and healthy adult female populations at Xizang Autonomous Region People's Hospital between March 2019 and July 2023. HPV positivity rates were compared across different ethnic groups and age strata, and temporal trends in HPV detection were analyzed. A total of 6498 adult women with HPV testing were included, with a mean age of (39.5±9.8) years, including 5440 Tibetan and 1058 Han women. The overall HPV positivity rate was 19.58%(1272/6498), predominantly single-type infections (14.99%), while double (3.71%) and triple-or-more infections (0.88%) were less common. Han women had a significantly higher HPV positivity rate than Tibetan women [29.30%(310/1058) The HPV positivity rate among adult women in high-altitude Xizang is relatively high, with significant differences in age-specific prevalence and dominant genotypes between Tibetan and Han women. Targeted measures, including HPV vaccination for young women and enhanced screening and treatment for both young and postmenopausal women, should be prioritized in this region.

Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

AIM: To compare the control effect of spherical and toric orthokeratology on low-to-moderate myopia with astigmatism(-1.00--1.50 DC)in adolescents.METHODS: The clinical data of 119 cases(119 eyes)of low-to-moderate myopia with astigmatism(-1.00--1.50 DC)adolescents who were treated and fitted with orthokeratology in the ophthalmology department of Sichuan Provincial People's Hospital from June 2021 to January 2022 were retrospectively analyzed. They were divided into spherical group, with 65 cases(65 eyes), and toric group, with 54 cases(54 eyes)according to the type of orthokeratology. The changes of uncorrected visual acuity(UCVA), axial length and corneal astigmatism before and after wearing lenses were recorded to evaluate the therapeutic effect.RESULTS: The UCVA of both the groups significantly improved at 1 and 2 a after wearing lenses(all P<0.01); corneal astigmatism decreased, but there was no significant difference(all P>0.05); the axial length was longer than that before wearing lenses(P<0.01). There were no statistical significant differences in the UCVA and corneal astigmatism between the spherical group and the toric group(Fintergroup=0.829,Pintergroup=0.364; Fintergroup=0.997,Pintergroup=0.320); and there were no statistical significant differences in the axial length growth between the spherical group and the toric group after wearing lenses for 1 a(0.18±0.11 mm vs 0.17±0.14 mm), and 2 a(0.17±0.10 mm vs 0.16±0.10 mm; all P>0.05).CONCLUSION: Both orthokeratology lenses can improve the UCVA, reduce corneal astigmatism, and delay axial length growth of adolescents with low-to-moderate myopia with astigmatism(-1.00--1.50 DC), and there are no significant differences in the control effect of spherical design orthokeratology and the toric design orthokeratology on myopia.

BACKGROUND:Carboxylesterase 1 and inflammatory factors play a crucial role in regulating lipid metabolism and glucose homeostasis.However,the effects of different exercise intensity interventions on carboxylesterase 1 and inflammatory factors in skeletal muscle of type 2 diabetic rats remain to be revealed. OBJECTIVE:To investigate the effects of different exercise intensity interventions on carboxylesterase 1 and inflammatory factors in skeletal muscle of type 2 diabetic rats. METHODS:Thirty-two 8-week-old male Sprague-Dawley rats were randomly divided into normal control group(n=12)and modeling group(n=20)after 1 week of adaptive feeding.Rat models of type 2 diabetes mellitus were prepared by high-fat diet and single injection of streptozotocin.After successful modeling,the rats were randomly divided into diabetic control group(n=6),moderate-intensity exercise group(n=6)and high-intensity intermittent exercise group(n=6).The latter two groups were subjected to treadmill training at corresponding intensities,once a day,50 minutes each,and 5 days per week.Exercise intervention in each group was carried out for 6 weeks.After the intervention,ELISA was used to detect blood glucose and blood lipids of rats.The morphological changes of skeletal muscle were observed by hematoxylin-eosin staining.The mRNA expression levels of carboxylesterase 1 and inflammatory cytokines were detected by real-time quantitative PCR.The protein expression levels of carboxylesterase 1 and inflammatory cytokines were detected by western blot and immunofluorescence. RESULTS AND CONCLUSION:Compared with the normal control group,fasting blood glucose,triglyceride,low-density lipoprotein cholesterol,insulin resistance index in the diabetic control group were significantly increased(P<0.01),insulin activity was decreased(P<0.05),and the mRNA and protein levels of carboxylesterase 1,never in mitosis gene A related kinase 7(NEK7)and interleukin 18 in skeletal muscle tissue were upregulated(P<0.05).Compared with the diabetic control group,fasting blood glucose,triglyceride,low-density lipoprotein cholesterol,and insulin resistance index in the moderate-intensity exercise group and high-intensity intermittent exercise group were down-regulated(P<0.05),and insulin activity was increased(P<0.05).Moreover,compared with the diabetic control group,the mRNA level of NEK7 and the protein levels of carboxylesterase 1,NEK7 and interleukin 18 in skeletal muscle were decreased in the moderate-intensity exercise group(P<0.05),while the mRNA levels of carboxylesterase 1,NEK7,NOD-like receptor heat protein domain associated protein 3 and interleukin 18 and the protein levels of carboxylesterase 1 and interleukin 18 in skeletal muscle were downregulated in the high-intensity intermittent exercise group(P<0.05).Hematoxylin-eosin staining showed that compared with the diabetic control group,the cavities of myofibers in the moderate-intensity exercise group became smaller,the number of internal cavities was reduced,and the cellular structure tended to be more intact;the myocytes of rats in the high-intensity intermittent exercise group were loosely arranged,with irregular tissue shape and increased cavities in myofibers.To conclude,both moderate-intensity exercise and high-intensity intermittent exercise can reduce blood glucose,lipid,insulin resistance and carboxylesterase 1 levels in type 2 diabetic rats.Moderate-intensity exercise can significantly reduce the expression level of NEK7 protein in skeletal muscle,while high-intensity intermittent exercise can significantly reduce the expression level of interleukin 18 protein in skeletal muscle.In addition,the level of carboxylesterase 1 is closely related to the levels of NEK7 and interleukin 18.

ObjectiveTo evaluate the effects of phases on the pharmacokinetic behavior of seven components from Banxia Xiexintang(BXT) in normal rats by investigating and comparing their pharmacokinetic profiles in different phase samples. MethodsThe phase separation of BXT was carried out by centrifugation-dialysis method, and three phase samples were obtained, including the precipitated phase(PP), colloidal phase(CP) and true solution phase(TP). A total of 24 male SD rats were randomly divided into BXT, PP, CP and TP groups(n=6). The BXT group was gavaged at a dose of 24.1 g·kg-1(calculated by the dosage of raw materials). After proper treatments, PP, CP and TP groups were administrated at the same dose as that of BXT group, respectively. Blood was collected from each group at set time points after gavage of BXT and the phase samples. The contents of 7 components(baicalin, wogonoside, wogonin, berberine, palmatine, ammonium glycyrrhizinate and isoliquiritin) in rat plasma were determined by ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry(UPLC-QqQ-MS/MS), and the pharmacokinetic parameters of each component were analyzed by DAS 2.0. ResultsThe peak concentration of baicalin was the highest among the blood-entered components in each group, followed by wogonoside. The results of the concentration-time curves and pharmacokinetic parameters of the 7 components showed that the area under the concentration-time curve(AUC) of isoliquiritin in the BXT group was the highest, followed by that in the CP group. AUC values of baicalin, wogonoside, wogonin and ammonium glycyrrhizinate in the BXT group were similar to those of the CP group, and AUC of palmatine in the BXT group was similar to that of the PP group. The elimination half-life(t1/2) values of baicalin and wogonoside in the BXT group was the longest, the t1/2 values of ammonium glycyrrhizinate and berberine were similar to those of the CP group, and the t1/2 of palmatine was similar to that of the PP group. The t1/2 of wogonin was the longest in the PP group, and the t1/2 of isoliquiritin was the longest in the TP group was the longest, which was similar to that in the PP group. Except for isoliquiritin, the other 6 components showed double peaks in the concentration-time curve of the PP group, indicating that the above components might be reabsorbed through the enterohepatic circulation in vivo, which resulted in the maintenance of high plasma concentrations for a long time, and consequently exhibited sustained-release properties. ConclusionThe pharmacokinetic characteristics of the components in different phases were different, and the CP phase may be the effective phase from the perspective of the pharmacological action of BXT. Compared with the BXT group, the in vivo action times of some components in the CP and PP groups were prolonged. The study explores the phase differences of traditional Chinese medicine(TCM) compound decoction in the aspect of pharmacokinetics, and verifies that the phase states from TCM compound decoction will affect the pharmacokinetic behaviors of the active components, which may consequently lead to the difference in in vivo effects.
