Objective Objective To analyze the potential spatial factors affecting the genetic differentiation of Oncomelania hupensis robertsoni in Yunnan Province. Methods A total of 13 administrative villages were selected from schistosomiasis-endemic areas of Yunnan Province as O. hupensis snail sampling sites. At least 200 snails were collected in each site, and the spatial variable data of each site were recorded, including longitude, latitude and altitude. Thirty active and Schistosoma japonicum uninfected O. hupensis snails were selected from each sampling site by means of the crawling method and the cercarial shedding method. Genomic DNA was extracted from O. hupensis snails. Following PCR amplification, purification of PCR amplification products and sequencing, the gene sequences of O. hupensis snail samples were spliced and edited using the DNAstar software and the NCBI database to yield the complete mitochondrial sequences of O. hupensis snails at each sampling site, and the mitochondrial genetic distance matrix of O. hupensis robertsoni was calculated at each sampling site. The geographical coordinates of each sampling site were marked using the software ArcGIS 10.2, and the straight-line geographical distance between each sampling site was calculated. The altitude difference, longitude difference and latitude difference between each sampling site were calculated using the Excel software, and the correlation between the mitochondrial genetic distance matrix of O. hupensis robertsoni and each spatial variable matrix was examined by using the Mantel test at 13 sampling sites in Yunnan Province. Results Among the 13 O. hupensis snail sampling sites in Yunnan Province, the largest mitochondrial genetic distance of O. hupensis robertsoni snail populations was seen between Anding Village, Nanjian Yi Autonomous County and Caizhuang Village, Midu County (26.244 2), and the largest geographical distance was seen between Dongyuan Village, Gucheng District and Cangling Village, Chuxiong County (272.64 km). The highest altitude difference was seen between Anding Village, Nanjian Yi Autonomous County and Dongyuan Village, Gucheng District (1 086.10 m), and the largest longitude difference was found between Qiandian Village, Eryuan County and Cangling Village, Chuxiong County (1.86°), while the largest latitude difference was measured between Leqiu Village, Nanjian Yi Autonomous County and Dongyuan Village, Gucheng District (1.81°). In addition, the mitochondrial genetic distance of O. hupensis robertsoni snail populations was positively correlated with altitude at 13 snail sampling sites in Yunnan Province (r = 0.542 8, P < 0.001), and showed no significant correlations with geographical distance (r = 0.093 4, P > 0.05), longitude (r = −0.199 5, P > 0.05) or latitude (r = 0.205 7, P > 0.05). Conclusion Altitude may be a potential spatial factor affecting the genetic differentiation of O. hupensis robertsoni in Yunnan Province.

Objective To investigate the prognosis of patients with triple-negative invasive lobular carcinoma (TN-ILC) undergoing breast-conserving surgery combined with radiotherapy (BCS+RT) versus total mastectomy. Methods A retrospective analysis was performed for 2 386 female patients with TN-ILC who underwent surgery in the SEER database from 2006 to 2018, and the baseline characteristics (age, histological grade, AJCC stage, etc.) were balanced by propensity score matching (PSM, 1∶1, caliper value 0.02), and breast cancer-specific survival (BCSS) and overall survival (OS) were compared by Kaplan-Meier method and COX regression analysis. Results A total of 1 056 pairs of patients were obtained after PSM, and the BCS+RT group had significantly better BCSS and OS than the total mastectomy group (both P<0.001). Stratified analyses showed that BCS+RT had a survival advantage in all subgroups except histologic grade Ⅰ and tumor stage Ⅰ. Multivariate analysis confirmed that BCS+RT was an independent protective factor (BCSS: HR=0.682, OS: HR=0.607, both P<0.001). Conclusions BCS+RT significantly improves survival compared with total mastectomy in patients with TN-ILC, supporting BCS+RT as the preferred treatment strategy for eligible patients.

Angle class Ⅱ malocclusion is often characterized by mandibular retraction and lip incompetence,which affects the patient's lateral appearance and may even lead to upper airway stenosis.It can be classified into dental and skeletal types.For skeletal class Ⅱ malocclusion patients with mandibular retraction during the peak growth period,mandibular anterior guidance with a functional orthodontic appliance is generally considered as the optimal clinical treatment approach.At present,there remains a paucity of clinical reports on the clinical application of bracket-free clear aligners in mandibular anterior guidance,both domestically and internationally.This article presented a case of an adolescent patient with skeletal class Ⅱ malocclusion accompanied with deep overbite treated with bracket-free clear aligner for mandibular anterior guidance in combination with intermaxillary class Ⅱ traction.During the treatment,vertical correction involved anterior intrusion of the anterior teeth to improve the deep overbite,while horizontal correction included maxillary and mandibular expansion to coordinate the width of the dental arches,and asymmetric anterior guidance was used to correct the midline deviation.After 35 months of treatment,the patient's convex facial profile and mandibular retrusion were significantly improved.The subspinale-nasion-supramentale angle(ANB)was decreased from 6.8° to 3.9°,the overbite and overjet were normalized,and the bilateral canine and molar reached a neutral relationship.The mentolabial sulcus depth(Si-LiPg′)and the soft tissue thickness of pogonion to pogonion(Pm-Pm′)were decreased,resulting in a shallower mentolabial sulcus and a more harmonized lateral facial soft tissue profile.The mandibular incisor to mandibular plane angle(IMPA)was decreased from 116.6° to 110.7°,indicating retraction of the lower incisors during mandibular anterior guidance.In conclusion,the orthodontic strategy of mandibular advancement with clear aligners in skeletal class Ⅱ malocclusion patients can avoid excessive overcompensation of the upper and lower anterior teeth and shorten the orthodontic treatment cycle.

Objective To evaluate the clinical efficacy of modified Yulinzhu Formula combined with plum-blossom needle tapping acupuncture in treating kidney-yang deficiency type of ovulatory dysfunction infertility(ODI).Methods A total of 100 ODI patients diagnosed at Hengshui Hospital of Traditional Chinese Medicine between January 2023 and January 2024 were enrolled and randomly divided into an observation group and a control group using a random number table,with 50 cases in each group.The control group received conventional western medical treatment,while the observation group received additional oral administration of modified Yulinzhu Formula and plum-blossom needle tapping acupuncture therapy.Treatment was administered for one menstrual cycle as a course,with three consecutive courses completed.After three months,clinical efficacy was assessed by comparing traditional Chinese medicine(TCM)syndrome scores,ovulation rate,pregnancy rate,proportion of type A endometrium,ovarian volume,antral follicle count(AFC),and adverse reactions between groups.Results(1)After treatment,the scores of TCM syndromes in the two groups were significantly improved(P＜0.05),and the improvement in the observation group was superior to that in the control group,the difference being significant(P＜0.05).(2)The total effective rate was 90.00％(45/50)in the observation group and 72.00％(36/50)in the control group.The curative effect of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(3)The ovulation rate,pregnancy rate and the proportion of type A endometrium in the observation group were significantly superior to those in the control group,and the differences were statistically significant(P＜0.05).(4)After treatment,the ovarian volume and the number of antral follicles in the two groups were significantly improved(P＜0.05),and the improvement in the ovarian volume and the number of antral follicles in the observation group was superior to that in the control group,the difference being significant(P＜0.05).(5)The incidence of adverse reactions was 8.00％(4/50)in the observation group and 24.00％(12/50)in the control group.The incidence of adverse reactions in the observation group was significantly lower than that in the control group,the difference was statistically significant(P＜0.05).Conclusion Modified Yulinzhu Formula combined with plum-blossom needle tapping acupuncture effectively improves clinical symptoms,enhances ovulation/pregnancy rates,increases type A endometrium,optimizes ovarian volume and AFC,and reduces adverse reactions in kidney-yang deficiency ODI patients.

Objective To investigate the value of serum tumor markers in the diagnosis of lung cancer.Methods A total of 138 patients with newly diagnosed lung cancer patient(lung cancer group)and 52 patients with benign lung diseases(control group)in Anhui NO.2 Provincial People's Hospital from June 2020 to March 2024 were selected as the research objects.The clinical data and serum tumor markers[neuron-specific enolase(NSE),cytokeratin 19 fragment(CYFRA21-1),carcinoembryonic antigen(CEA),Pro-gastrin-relea-sing peptide(ProGRP)and squamous cell carcinoma antigen(SCC)]of all groups were compared.Results There were significant differences in age and smoking history between the two groups(P＜0.05).The serum levels of NSE,CYFRA21-1,CEA,ProGRP and SCC in lung cancer group were significantly higher than those in control group,and the differences were statistically significant(P＜0.05).The results of binary Logistic regression analysis showed that smoking history,age,CYFRA21-1 and CEA levels were all influen-cing factors for the occurrence of lung cancer(P＜0.05).Receiver operating characteristic(ROC)curve analy-sis results showed that the area under the curve(AUC)of smoking history,age,CEA and CYFRA21-1 in the combined diagnosis of lung cancer was 0.906(95％CI:0.865-0.947),which was higher than the AUC for the individual diagnosis of each index.The levels of serum CYFR21-1 and CEA in the stage Ⅰ—Ⅱ group were significantly lower than those in the stage Ⅲ-Ⅳ group,and the difference was statistically significant(P＜0.05).The results of binary Logistic regression analysis showed that CYFRA21-1 and CEA levels were influ-ential factors in the occurrence of lung cancer stage Ⅲ-Ⅳ(P＜0.05).ROC curve analysis showed that the AUC of CEA and CYFRA21-1 for the diagnosis of lung cancer stage Ⅲ-Ⅳ were 0.750(95％CI:0.667-0.832)and 0.771(95％CI:0.691-0.852),respectively.The AUC of combined diagnosis was 0.834(95％CI:0.765-0.902),the sensitivity was 58.9％,and the specificity was 95.3％.Conclusion Smoking history,age,CEA,and CYFRA21-1 may be potential biomarkers for the diagnosis and prognosis of lung cancer,espe-cially CEA and CYFRA21-1,which are also of great significance for the staging of lung cancer from stage Ⅲ to stage Ⅳ.

Evidence-based public health, as the forefront of modern public health practice, has increasingly important in public health field. However, a significant gap remains between the available evidence and its practical application. Effectively disseminating and implementing evidence-based public health practice in real-world settings has become a key challenge in contemporary public health research. In this context, Implementation Science has emerged as a vital discipline. This paper explores the critical role of Implementation Science in public health, reviews the origins and core components of the Consolidated Framework for Implementation Research (CFIR), and analyzes the current application of CFIR in public health through bibliometric methods. Additionally, it discusses specific examples to further elucidate the steps involved in using the CFIR and its application contexts. The findings indicate that since 2015, research on CFIR in public health has progressively increased, showing a continuous upward trend. CFIR applications mainly address context-specific facilitators, health decision-making, barrier and facilitator identification, and community-based participatory evaluation, predominantly employing qualitative and mixed-methods research. This paper not only reviews and analyzes the current use of CFIR in public health but also provides a detailed discussion on its application. The goal is to offer valuable insights for the development of Implementation Science research within China's public health sector.
