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.

Bile-processed Coptidis Rhizoma（B-pCR）， first documented in Shengji Zonglu， is a unique processed products of Coptidis Rhizoma（CR） characterized by "mutual enhancement processing" and "enhancing the cold property of cold-natured herbs". Pig bile can enhance the bitter and cold properties of CR， yielding potent effects in purging excess fire from the liver and gallbladder. The processing increases the dissolution of alkaloids such as berberine， coptisine， and palmatine， while introducing bile acids from pig bile， including taurine-type and glycine-type cholic acids. This enhances its pharmacological effects， such as antipyretic activity， regulation of glucose and lipid metabolism disorders， and intestinal absorption. Traditional processing techniques and quality standards for B-pCR are outlined in the Shanghai Traditional Chinese Medicine（TCM） Decoction Pieces Processing Standard and the Gansu TCM Processing Standard. However， incomplete specifications for critical process parameters and quality criteria significantly impact its production and clinical application. A review of research over the past two decades on the processing history， process optimization， quality evaluation， material basis， and changes in pharmacological effects and properties of B-pCR reveals that the pretreatment method and dosage of pig bile， and processing temperature are key factors influencing its quality. Furthermore， current quality standards lack specific indicators. Additionally， the enhancement of the cold property and medicinal efficacy direction of B-pCR is not only associated with changes in alkaloid groups but also depend on the synergistic effects of bile acids. This review can provide insights for improving the quality evaluation system of B-pCR.

Objective: To investigate the factors influencing the co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia, so as to provide a data foundation and theoretical basis for developing targeted intervention measures. Methods: In September and October 2024, a stratified cluster random sampling method was employed to select 139 102 students from 539 schools across 12 leagues/cities and 103 banners/counties in Inner Mongolia Autonomous Region. Participants who were diagnosed with allergic rhinitis by a doctor at least once within one year and had a body mass index ≥ 28 kg/m 2 were considered to have comorbid conditions. Results: The coprevalence rate of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia was 6.4% (8 931 cases). Lasso-Logistic regression revealed that nonboarding status, higher maternal education, consuming high protein foods ≥1 time daily, occasionally or never eating breakfast, engaging in moderate to vigorous physical activity for ≥60 minutes on fewer than half of holidays, and having been exposed to second hand smoke in person within the past seven days were associated with higher odds ratios for co-prevalence of allergic rhinitis and obesity( OR = 1.23 , 1.22-1.63, 1.20, 1.19, 1.38, 1.35); being female, higher grade level, residence in flag/county/district areas, non only child status, never having consumed a full glass of alcohol, non hypertensive status, and households without pets were associated with lower co-prevalence risks ( OR =0.65, 0.67-0.77, 0.81, 0.87, 0.73, 0.41, 0.68) (all P <0.05). The ROC curve indicated an area under the curve of 0.64 for the predictive model, demonstrating satisfactory discriminatory ability. The calibration curve showed consistency between predicted and actual occurrence probabilities. Conclusions The co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia is closely associated with demographic characteristics, dietary behaviours, and lifestyle habits. Future prevention and control strategies should prioritize these factors to implement targeted interventions.

ObjectiveTo investigate the therapeutic efficacy of Danggui Shaoyaosan （DSS） on renal injury in db/db mice and its impact on endoplasmic reticulum stress （ERS） in renal tissues. MethodsThirty 8-week-old male db/db mice and six db/m mice were acclimated for one week， after which urinary microalbumin and blood glucose levels were monitored to establish a diabetic kidney disease （DKD） model. The model mice were randomly divided into a model group， an irbesartan group， and three DSS treatment groups with different doses （16.77， 33.54， and 67.08 g·kg^-1·d^-1）. A normal group was set as control. Each group was intragastrically administered with the corresponding drugs or saline for 8 weeks. After the intervention， general conditions were observed. Serum cystatin C （Cys-C）， 24-hour urinary total protein （24 h-UTP）， 24-hour urinary microalbumin （24 h-UMA）， urinary creatinine （Ucr）， and urea nitrogen （UUN） were measured. Transmission electron microscopy （TEM） was used to observe glomerular basement membrane （GBM） and ultrastructural changes of the endoplasmic reticulum （ER） in glomerular endothelial cells. Western blot， real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and immunohistochemistry were used to analyze renal tissue structure and the expression of GRP78， CHOP， and related markers. ResultsCompared with the normal group， the mice in the model group showed curled posture， sluggish response， poor fur condition， increased levels of Cys-C， 24 h-UTP， 24 h-UMA， and UUN （P<0.05）， while Ucr decreased （P<0.05）. The GBM was significantly thickened， with podocyte and foot process fusion. The protein expressions of GRP78， CHOP， and ATF6 were significantly upregulated （P<0.05）， the mRNA levels of GRP78 and CHOP increased （P<0.05）， and immunohistochemistry showed an enhanced GRP78 signal （P<0.05）. After treatment， the mice exhibited improved behavior， normalized GBM and podocyte structure， improved ER morphology and markedly better biochemical indicators. Western blot， Real-time PCR， and immunohistochemistry indicated that the ERS-related markers were downregulated in the DSS treatment groups （P<0.05）， suggesting alleviated ERS and improved renal function. ConclusionDSS can effectively ameliorate renal pathological damage in db/db mice， possibly by regulating ERS in glomerular endothelial cells， although the underlying signaling mechanisms require further investigation.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

BackgroundPatients with colorectal cancer are frequently comorbid with depression， which severely affects the quality of life and treatment compliance， while compromising the efficacy of anticancer treament and prognosis. Current therapeutic strategies still have notable limitations， particularly the lack of systematic and targeted synergistic regimens that integrate oncological management and anti-depressive intervention. It is of great clinical significance to explore a safe and effective new comprehensive intervention protocol and clarify its underlying mechanism of action. ObjectiveTo explore the effectiveness and safety of Shugan Yunpi Decoction in alleviating depressive and anxiety symptoms in colorectal cancer patients with depressive disorder through the PI3K-AKT signaling pathway， in order to provide references for the comprehensive treatment of colorectal cancer and depressive disorder. MethodsThis study was a randomized controlled trial. A total of 106 patients admitted to the Baoding No.1 Hospital of traditional Chinese medicine from November 2023 to July 2025 were enrolled， who met the diagnostic criteria for the Chinese protocol of diagnosis and treatment of colorectal cancer （2023 edition） and the diagnostic criteria for depressive disorder as specified in the Chinese Classification and Diagnostic Criteria of Mental Disease， third edition （CCMD-3）. Patients were divided into the study group and the control group using a random number table， with 53 cases in each group. The control group received conventional chemotherapy combined with traditional Chinese medicine five-element music therapy， while the study group received conventional chemotherapy combined with Shugan Yunpi Decoction therapy. Both groups were treated for 8 weeks. Depressive and anxiety symptoms were assessed using the Hamilton Depression Scale-17 item（HAMD-17） and Hamilton Anxiety Scale （HAMA）， respectively. Western blot protein immunoblotting was used to detect the expression levels of PI3K， AKT， and pAKT. Real-time fluorescence quantitative reverse transcription polymerase chain reaction （qRT-PCR） was used to detect the expression levels of PI3K mRNA and AKT mRNA. Adverse reactions were recorded using a self-designed adverse reaction record form. ResultsRepeated measures analysis of variance showed that the time effects （F=139.336， 234.747）， group effects （F=43.900， 101.266）， and time-group interaction effects （F=13.409， 43.216） for HAMD-17 and HAMA scores in both groups were statistically significant （P<0.01）. After 4 and 8 weeks of treatment， the HAMD-17 and HAMA scores in both groups were lower than those before treatment， with statistically significant differences （P<0.05）. HAMD-17 and HAMA scores in the study group were lower than those in the control group （P<0.05）. The time effects （F=571.356， 309.266， 414.492）， group effects （F=6.901， 26.361， 39.362）， and time-group interaction effects （F=18.592， 19.266， 33.484） for the protein expression levels of PI3K， AKT， and pAKT in both groups were all statistically significant （P<0.01）. After 8 weeks of treatment， the protein expression levels of PI3K and pAKT in the study group were lower than those in the control group， while the AKT protein expression level was higher than that in the control group（P<0.01）. The time effects （F=338.555， 225.059）， group effects （F=5.429， 9.726）， and time-group interaction effects （F=12.953， 21.214） for PI3K mRNA and AKT mRNA expression levels in two groups were all statistically significant （P<0.01）. After 8 weeks of treatment， the expression levels of PI3K mRNA and AKT mRNA in the study group were lower than those in the control group （P<0.05）. The incidence of adverse reactions in the study group was lower than that in the control group （χ²=4.810， P<0.05）. ConclusionShugan Yunpi Decoction may help to ameliorate depressive and anxiety symptoms in colorectal cancer patients with depressive disorder by regulating the PI3K-AKT signaling pathway， decreasing the levels of PI3K， pAKT， PI3K mRNA， and AKT mRNA， with a favorable safety profile. ［Funded by Baoding City Science and Technology Planning Project （number， 2341ZF291）］

Phacoemulsification represents the mainstream, efficient, and safe surgical modality for cataract treatment, and continuous technological advances have further improved the safety profile of this procedure in ordinary patients. However, patients with high myopia feature inherent anatomical abnormalities of the eyeball, leading to a fundamental incompatibility with conventional phacoemulsification protocols. Such patients face a markedly elevated risk of both anterior and posterior segment perioperative complications, posing a persistent clinical challenge in cataract surgery. Focusing on the unique ocular anatomical characteristics associated with high myopia, this review systematically summarizes the distinct traumatic effects and pathological impacts of phacoemulsification on the anterior and posterior ocular segments of affected patients. Moving beyond generalized discussions of routine cataract management, it consolidates clinical evidence specific to this special-population patients, aiming to provide refined references for perioperative risk prevention and control in cataract patients complicated with high myopia.

This review delves into the pivotal role of necrotic apoptosis in Alzheimer's disease(AD),with a focus on treatment strategies,drug development,prospects,and challenges,highlighting its significance in the progression of the disease.Firstly,necrotic apoptosis plays a crucial role in the pathogenesis of AD,particularly in association with the abnormal metabolism of β-amyloid(Aβ)and Tau proteins.The primary focus of drug design is to regulate the metabolism pathways of these two proteins to slow down or inhibit the progression of necrotic apoptosis.Secondly,the progress in drug development further emphasizes the importance of necrotic apoptosis in treating AD.Current research mainly focuses on drugs that affect the metabolism of Aβ and Tau proteins,such as lecanemab.Still,inconsistent result underscore the necessity for a more comprehensive understanding of the molecular mechanisms of necrotic apoptosis.Finally,the prospects and challenges of necrotic apoptosis research in AD are thoroughly discussed.A deeper understanding of necrotic apoptosis contributes to a better comprehension of the pathological mechanisms of AD but also may reveal new therapeutic targets.However,challenges such as multifactorial influences and the selection of treatment timing necessitate further in-depth research in the future.In conclusion,this review advocates for future research to deepen the understanding of the molecular mechanisms of necrotic apoptosis,enhance research on treatment strategies,gain a deeper understanding of its cross-regulation with other cell death pathways,and promote collaboration between basic research and clinical practice to advance the comprehensive understanding and treatment of Alzheimer's disease and necrotic apoptosis.

Objective To explore the molecular mechanism by which SOS Ras/Rac guanine nucleotide exchange factor 1-intronic transcript 1(SOS1-IT1)affects enhancer of zeste homolog 2(EZH2)protein expression in endometrial cancer cells Ishikawa and RL95-2.Methods Lentiviral transfection of short hairpin RNA(shRNA)and overexpression plasmid were used in Ishikawa and RL95-2 cell lines to knock down and overexpress SOS1-IT1.The mechanism of EZH2 expression regulation was studied using Real-time PCR,Western blotting,and chromatin immunoprecipitation.Results The expression of SOS1-IT1 and EZH2 genes was positively correlated in endometrial cancer tissues.Knocking down SOS1-IT1 significantly reduces the expression of EZH2,inhibited the proliferation and migration of Ishikawa and RL95-2 cells,and could reduced the acetylation of histone H3 at position 27(H3K27)and the enrichment of CREB binding protein(CBP)in the EZH2 gene promoter region.Overexpression of SOS1-IT1 could increased the expression of EZH2 and enhance the acetylation of H3K27 and the enrichment of CBP.CBP could bind to SOS1-IT1 RNA,and this binding ability was weakened when CBP was knocked down.Conclusion SOS1-IT1 can promote the expression level of EZH2 in endometrial cancer cells Ishikawa and RL95-2 by regulating the acetylation modification level of the EZH2 gene promoter region,thereby affecting the proliferation and migration ability of endometrial cancer cells.

Objective:To compare the effects of manual acupuncture(MA),electroacupuncture(EA),and moxibustion on knee joint cartilage morphology,serum inflammatory factors interleukin(IL)-6 and IL-10,matrix metalloproteinase 13(MMP13),and intestinal flora composition in knee osteoarthritis(KOA)model rats.Methods:Forty male specific-pathogen-free Sprague-Dawley rats aged seven weeks were randomly divided into a normal group(n=8)and a KOA modeling group(n=32).The KOA model was established using sodium iodoacetate induction.The KOA modeling rats were further randomly divided into a model group,an MA group,an EA group,and a moxibustion group,with 8 rats in each group.In the MA,EA,and moxibustion groups,interventions targeting the right Futu(ST32)and Zusanli(ST36)were performed for 15 min,once every other day,for 14 sessions.The normal and model groups were bundled on the self-made fixation frame for 15 min.The rat knee joint diameter was measured on the 8th day of adaptive feeding,after successful modeling,and after the 14th intervention.Lequesne behavioral scoring was performed after successful modeling and after the 14th intervention.After the 14th intervention,hematoxylin-eosin(HE)staining and Masson staining were performed with the cartilage sections of the right knee joint.The pathomorphological changes of the rat joint cartilage were observed and quantified by Mankin's score.Enzyme-linked immunosorbent assay was used to detect the rat serum levels of IL-6,IL-10,and MMP13.Additionally,16S rDNA sequencing was used to detect the composition of rat fecal flora.Results:Compared to the normal group,the right knee joint diameter and the Lequesne score were significantly increased in the model group(P<0.01).Compared to the model group,the right knee joint diameter and the Lequesne score of rats in the MA,EA,and moxibustion groups were significantly reduced(P<0.01),with no significant differences among the three intervention groups(P>0.05).HE staining and Masson staining revealed disordered cartilage structure in the model group,which was improved following interventions in the MA group,EA group,and moxibustion group.Mankin's score was significantly higher in the model group versus the normal group(P<0.05)while significantly lower in the MA,EA,and moxibustion groups versus the model group(P<0.05).Serum analysis showed elevated IL-6 and MMP13 levels and reduced IL-10 level in the model group versus the normal group(P<0.05).Compared to the model group,the serum IL-6 level was significantly reduced(P<0.05),and the IL-10 level was significantly increased(P<0.05)in the MA,EA,and moxibustion groups,but without statistical differences among the three intervention groups(P>0.05);moreover,the MMP13 level in the moxibustion group was significantly lower than that in the model group(P<0.05).The alpha diversity analysis of intestinal flora showed no statistical difference in the number of operational taxonomic units(OTUs)and alpha diversity index among groups(P>0.05).Intestinal flora beta diversity analysis revealed significant differences among groups(P<0.05).Intestinal flora composition analysis showed significantly increased relative abundance of Lactobacillus(P<0.05)and significantly decreased relative abundance of Eubacterium_coprostanoligenes(P<0.05)in the model group compared to the normal group;compared to the model group,the relative abundances of Firmicutes,Lactobacillus,and Romboutsia in the MA,EA,and moxibustion groups were significantly reduced(P<0.05);the relative abundance of Bacteroidetes and Lachnospiraceae_NK4A136 in the MA group increased significantly(P<0.05);Bacteroidetes and Ruminococcaceaae_UGC-005 increased significantly in the moxibustion group(P<0.05).Conclusion:MA,EA,and moxibustion effectively reduced knee joint swelling,improved cartilage tissue morphology,optimized intestinal flora composition,down-regulated expression levels of serum pro-inflammatory factors IL-6 and MMP13,and increased expression level of anti-inflammatory factor IL-10 in KOA rats.Among them,moxibustion exhibited the most obvious regulatory effect on inflammatory factors.
