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.

ObjectiveTo investigate whether Danggui Shaoyaosan (DSS) inhibits oxidative stress and alleviates inflammation via the Ras homolog family member A (RhoA)/Rho-associated coiled-coil containing protein kinase 1 (ROCK)/nuclear factor kappa-B (NF-κB) signaling pathway, thereby delaying the progression of diabetic kidney disease (DKD) and exerting a nephroprotective effect. MethodsEight db/m mice were assigned to the normal group, and forty 8-week-old db/db mice were randomly divided into the model group, DSS low-dose group (8.39 g·kg-1), DSS medium-dose group (16.77 g·kg-1), DSS high-dose group (33.54 g·kg-1), and irbesartan group (0.025 g·kg-1), with eight mice in each group. All groups were administered the corresponding treatment by gavage once daily for 12 weeks. The normal and model groups received an equal volume of saline. During administration, changes in body weight, fasting blood glucose (FBG), and 24 hour urinary protein (24 h UTP) were observed. After 12 consecutive weeks of administration, hematoxylin-eosin (HE) staining and Masson's trichrome staining were used to observe renal histopathological changes in each group. The levels of reactive oxygen species (ROS) in renal tissue were detected using the dihydroethidium (DHE) method. The expression levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in renal tissue were determined. Serum interleukin-1β (IL-1β) and interleukin-6 (IL-6) levels were measured using enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of RhoA, ROCK1, and NF-κB p65 in renal tissues were detected by Real-time quantitative polymerase chain reaction (Real-time PCR). Protein expression levels of fibronectin (FN), Collagen Ⅳ(Col Ⅳ), transforming growth factor-β1 (TGF-β1), RhoA, ROCK, and NF-κB p65 in renal tissues were determined by Western blot. ResultsCompared with the normal group, the model group showed significantly increased body weight, FBG, and 24 h UTP levels (P<0.01), elevated serum IL-1β and IL-6 levels, enlarged glomerular volume, diffuse mesangial expansion, increased mesangial matrix, and marked collagen fiber proliferation in renal tissues. SOD activity was decreased, while MDA, ROS, RhoA, ROCK1, and NF-κB p65 mRNA expression levels were increased (P<0.01), and the protein expression levels of FN, Col Ⅳ, TGF-β1, RhoA, ROCK, and NF-κB p65 were also elevated (P<0.01). Compared with the model group, the DSS low-, medium-, and high-dose groups and the irbesartan group showed reductions in body weight, FBG, and 24 h UTP, decreased serum IL-1β and IL-6 levels, varying degrees of improvement in renal histopathology, increased SOD activity, decreased MDA levels, reduced ROS expression, and significantly downregulated RhoA, ROCK1, and NF-κB p65 mRNA expression (P<0.05, P<0.01), as well as reduced protein expression levels of FN, Col Ⅳ, TGF-β1, RhoA, ROCK, and NF-κB p65 (P<0.05, P<0.01). ConclusionDSS can alleviate oxidative stress and inflammation, reduce extracellular matrix deposition, and delay renal fibrosis progression in db/db mice. Its mechanism may be related to the inhibition of the RhoA/ROCK/NF-κB signaling pathway, thereby exerting a therapeutic effect on DKD.

The paper summarizes Professor YANG Jun's experience in treatment of refractory facial paralysis with the refined mode of acupuncture and moxibustion, so as to provide new ideas and methods for the disease treated with acupuncture and moxibustion. Professor YANG Jun puts forward the refined mode of diagnosis and treatment of acupuncture and moxibustion for refractory facial paralysis. On the basis of syndrome/pattern differentiation of TCM, combined with meridian theory and modern anatomy, the symptom differentiation and meridian differentiation are performed accurately. By selecting local acupoints (e.g. Touwei [ST8], Sibai [ST2], Cuanzhu [BL2] and Yangbai [GB14]), distal acupoints (e.g. Zusanli [ST36], Hegu [LI4] and Jinsuo [GV8]), specific acupoints (e.g.Qianzheng [EX-HN16] and Touqiaoyin [GB11]) and the acupoints for regulating the mind (e.g. Dazhui [GV14] and Shuigou [GV26]), the prescription is composed. The different needling techniques are delivered at the acupoints (e.g. point-to-point needling with long needle, stuck needling by lifting and dragging, and balance needling on the healthy side). Besides, the facial rehabilitation is considered as the adjuvant treatment. This mode of treatment obtains the precise diagnosis and treatment to achieve the utmost therapeutic effects.

To introduce and analyze guideline terminology related to clinical question formulation, evidence retrieval and appraisal, and recommendation development. A systematic search was conducted in guideline development manuals and relevant methodological literature, covering publications up to October 25, 2024. Terminology related to the three aforementioned stages of related to guideline development was extracted from the included literature, standardized, and refined through consensus meetings to finalize a comprehensive terminology list and definitions. A total of 30 guideline development manuals and 15 methodological articles were included, and 23 core terms were identified. It is recommended to develop a standardized and scientifically sound guideline terminology system with unified naming, clear definitions, and alignment with the linguistic environment and usage habits in China. At the same time, it is essential to strengthen terminology training for both guideline developers and users based on this system, in order to deepen their correct understanding and proper application of guideline terminology.

OBJECTIVE:
To evaluate the effect of palliative care on drug use, medical service utilization and medical expenditure of patients with advanced cancer.
METHODS:
A cohort of patients including pal-liative care and standard care was constructed using the medical records of the patients in Peking University Cancer Hospital from 2018 to 2020, and coarsened exact matching was used to match the two groups of patients. The average monthly opioid consumption, hospitalization rate, intensive care unit (ICU) rate and operation rate, and the average monthly total cost were selected to evaluate drug use, medical service utilization and medical expenditure. Chi-square test and Wilcoxon signed rank test were used to compare the differences between the two groups before and after exposure and the change in the palliative care group. The net impact of palliative care on the patients was calculated using the difference-in-differences analysis.
RESULTS:
In this study, 180 patients in the palliative care group and 3 101 patients in the stan-dard care group were finally included in the matching, and the matching effect of the two groups was good (L1 < 0.1). Before and after exposure, the average monthly opioid consumption in the palliative care group was significantly higher than that in the standard care group (Before exposure: 0.3 DDD/person-month vs. 0.1 DDD/person-month, P < 0.01; After exposure: 0.7 DDD/person-month vs. 0.1 DDD/person-month, P < 0.01; DDD refers to defined daily dose), palliative care significantly increased the average monthly opioid consumption in the patients (0.3 DDD/person-month, P < 0.01). The hospitalization rate (48.9% vs. 74.3%, P < 0.01) and operation rate (3.9% vs. 8.8%, P < 0.01) of the patients in palliative care group were significantly lower than those in standard care group, and the ICU rate became similar between the two groups (1.1% vs. 1.6%, P=0.634). Palliative care significantly reduced the patients ' hospitalization rate (-25.6%, P < 0.01), ICU rate (-4.9%, P < 0.01) and operation rate (-14.5%, P < 0.01). Before and after exposure, the average monthly total costs of pal-liative care group were slightly higher than those of standard care group (Before exposure: 20 092.3 yuan vs. 19 132.8 yuan, P=0.725; After exposure: 9 719.8 yuan vs. 8 818.8 yuan, P=0.165). Palliative care increased the average monthly total cost by 2 208.8 yuan, but it was not statistically significant (P=0.316).
CONCLUSION
Palliative care can increase the opioid consumption in advanced cancer patients, reduce the rates of hospitalization, ICU and surgery, but has no significant effect on medical expenditure.

Given that ovarian stimulation is vital for assisted reproductive technology (ART) and results in elevated serum estrogen levels, exploring the impact of elevated estrogen exposure on oocytes and embryos is necessary. We investigated the effects of various ovarian stimulation treatments on oocyte and embryo morphology and gene expression using a mouse model and estrogen-treated mouse embryonic stem cells (mESCs). Female C57BL/6J mice were subjected to two types of conventional ovarian stimulation and ovarian hyperstimulation; mice treated with only normal saline served as controls. Hyperstimulation resulted in high serum estrogen levels, enlarged ovaries, an increased number of aberrant oocytes, and decreased embryo formation. The messenger RNA (mRNA)-sequencing of oocytes revealed the dysregulated expression of lysine-specific demethylase 6b (Kdm6b), which may be a key factor indicating hyperstimulation-induced aberrant oocytes and embryos. In vitro, Kdm6b expression was downregulated in mESCs treated with high-dose estrogen; treatment with an estrogen receptor antagonist could reverse this downregulated expression level. Furthermore, treatment with high-dose estrogen resulted in the upregulated expression of histone H3 lysine 27 trimethylation (H3K27me3) and phosphorylated H2A histone family member X (γ-H2AX). Notably, knockdown of Kdm6b and high estrogen levels hindered the formation of embryoid bodies, with a concomitant increase in the expression of H3K27me3 and γ-H2AX. Collectively, our findings revealed that hyperstimulation-induced high-dose estrogen could impair the demethylation of H3K27me3 by reducing Kdm6b expression. Accordingly, Kdm6b could be a promising marker for clinically predicting ART outcomes in patients with ovarian hyperstimulation syndrome.

OBJECTIVES:
This study aims to investigate factors influencing dental arch development in patients aged 0-6 years with cleft palate after Sommerlad-Furlow (SF) palatoplasty.
METHODS:
A total of 183 patients who underwent primary SF repair for cleft lip and palate before 18 months of age were included. Follow-ups were conducted at different ages, and digital dental casts of the maxillary dental arch were obtained using 3-matic Research 12.0 software. The length and width of the dental arch and palate were measured to explore developmental changes in the maxillary dental arch of the patients after the procedure. The study also investigated the influence of gender, age, cleft palate type, and relaxation incision on maxillary dental arch development.
RESULTS:
After SF, maxillary dental arch measurements showed statistically significant differences between children aged 0-2 years and those aged 3-6 years (P<0.05). However, no statistically significant differences were observed among different age groups within the 3-6 years range. Statistically significant differences were detected between males and females, with males having greater width of the posterior dental arch and palate (P=0.001) and shorter length of the anterior dental arch and entire dental arch (P<0.05). The unilateral cleft lip and palate group had shorter dental arch length (P<0.01) and wider posterior palate (P<0.01) than the cleft palate only group. Maxillary dental arch measurements had no statistically significant differences between groups with or without a relaxing incision.
CONCLUSIONS
Gender and age influence the width of the maxillary dental arch in children aged 0-6 years after SF, while age and cleft palate type affect dental arch length.

In recent years, the exploration and development of artificial intelligence (AI) technology in clinical trials for liver diseases have promoted the continuous innovation of research methods and processes in this field. AI has gradually become an important technical tool for various links of clinical trial including patient selection, risk stratification, endpoint evaluation, and result interpretation. Nevertheless, the standardized integration of AI into clinical trials still faces the methodological challenges such as data quality control, model interpretability, and causal inference. From the perspective of methodology, this article systematically reviews the principal application scenarios of AI as an object under investigation (validation trials) and as a research tool (supportive trials) in clinical trials for liver diseases, as well as the major methodological challenges of AI-related clinical trials along and the corresponding solution strategies, in order to provide methodological guidance for promoting the scientific and standardized implementation of AI technologies.

Objective:To explore the effect of ultrasound-guided stellate ganglion block (SGB) combined with cognitive behavioral therapy for insomnia (CBT-I) in the treatment of chronic insomnia.Methods:A total of 69 patients with chronic insomnia admitted to the Nanjing First Hospital from January 2023 to February 2024 were selected and randomly divided into the CBT-I alone group (simple group, 34 cases) and the SGB combined with CBT-I group (combined group, 35 cases) using a random number table. Both groups received treatment for 8 weeks. The simple group was treated with CBT-I twice a week, 1 hour each time. The combined group, on the basis of the simple group, received ultrasound-guided SGB with 4 ml of 1% lidocaine, which was performed once a day, alternately on the left and right sides, for 7 consecutive days each time, with a total of 14 injections in the 1st and 5th weeks. One week before treatment and 8 weeks after treatment, the Pittsburgh Sleep Quality Index (PSQI) and sleep diary were used to record patients′ subjective sleep quality; Actigraph was used to record objective sleep status; the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were used to assess patients′ emotional status. Adverse reactions such as hoarseness, pneumothorax, bleeding, and infection were recorded.Results:After 8 weeks of treatment, the effective rate was 76.5%(26/34) in the simple group and 94.3%(33/35) in the combined group, with a statistically significant difference (χ 2=8.433, P<0.05). Before treatment, there was no significant difference in PSQI scores between the two groups ( P>0.05). After 8 weeks of treatment, the PSQI scores of both groups were lower than those before treatment, and the PSQI score of the combined group was lower than that of the simple group, with a statistically significant difference ( P<0.05). Before treatment, there were no significant differences in sleep parameters from sleep diaries and Actigraph between the two groups (all P>0.05). Compared with before treatment, after treatment, the total sleep time and time in bed were prolonged, and sleep efficiency, the proportion of deep sleep, and the proportion of rapid eye movement sleep were increased in both groups; these indicators in the combined group were better than those in the simple group, with statistically significant differences (all P<0.05). Compared with before treatment, the sleep onset latency was shortened and the number of awakenings was reduced in both groups after treatment, and the combined group was better than the simple group, with statistically significant differences (all P<0.05). Before treatment, there were no significant differences in SAS and SDS scores between the two groups (all P>0.05). After treatment, the SAS and SDS scores of both groups were lower than those before treatment, and the SAS and SDS scores of the combined group were lower than those of the simple group, with statistically significant differences (all P<0.05). During treatment, 2 cases in the combined group developed hoarseness, which relieved spontaneously after 2 hours, and no other complications occurred. Conclusions:Ultrasound-guided SGB combined with CBT-I can significantly improve the nighttime sleep quality of patients with chronic insomnia.
