Based on the close structural and functional associations of the Shaoyang （少阳） channel and related zang-fu （脏腑） organs with the brain and the pharynx， this paper proposes that the pathogenesis of post-stroke dysphagia involves constraint and stagnation of the pivot mechanism， binding of phlegm and stasis， frenetic stirring of ministerial fire， and incoordination of the spirit mechanism， ultimately leading to loss of pharyngeal function. An acupuncture therapy centered on regulating the pivot and unblocking the orifice is established. Acupoints of the Shaoyang channel， including Fengchi （GB 20）， Wangu （GB 12）， Yifeng （SJ 17）， and Waiguan （SJ 5）， are selected to regulate the pivot and treat the root； acupoints of the Du （督） and Ren （任） channels， including Fengfu （GV 16）， Lianquan （CV 23）， and Tiantu （CV 22）， are used to unblock the orifice and treat the branch. In addition， staged treatment can be applied according to syndrome differentiation. In the acute stage with predominant phlegm turbidity， Fenglong （ST 40）， Yinlingquan （SP 9）， Jinjin （EX-HN 12）， and Yuye （EX-HN 13） are added to resolve phlegm and facilitate orifice function. During the recovery stage with excess ministerial fire scorching the pharynx， Zulinqi （GB 41） and Zhaohai （KI 6） are added to drain fire and nourish yin； when ministerial fire disturbs the spirit， Tongli （HT 5） and Neiguan （PC 6） are added to calm the spirit and the heart. During the chronic stage with blood deficiency and collateral stasis， Zusanli （ST 36） and Sanyinjiao （SP 6） are added to nourish blood and unblock collaterals. In clinical practice， the angle and depth of needling are adjusted based on the stage of dysphagia， with the combination of elongated needles and medicinal moxibustion are used to enhance the therapeutic effect.

Objective To investigate the association between dietary patterns and adolescent development in girls in Pudong New Area，Shanghai. Methods Using a stratified cluster sampling method, a total of 998 girls were selected from the cohort of growth, development, and health of children and adolescents in Pudong New Area of Shanghai. Physical development examinations and dietary surveys were conducted on these girls. Principal component analysis was used to determine girls' dietary patterns, and their relationship with adolescent development was analyzed using logistic regression. Results Among the 998 participants, 770 (77.15%) were pubertal girls. The factor analysis identified three dietary patterns, fungi and algae~nuts~legumes pattern, meat-vegetables and fruits-cereals pattern, and milk-eggs pattern. Logistic regression analysis revealed that after adjusting for age, waist circumference, residential district, mother's education level, and father's education level, the Q2 level (OR=0.54, 95% CI: 0.30-0.99), Q3 level (OR=0.50, 95% CI: 0.27-0.91), and Q4 level (OR=0.49, 95% CI: 0.26-0.90) of the fungi and algae-nuts-legumes pattern were negatively correlated with adolescent development. The Q2 level (OR=0.48, 95% CI: 0.27-0.87) and Q3 level (OR=0.49, 95% CI: 0.27-0.88) of the milk-eggs pattern were also negatively correlated with adolescent development. Conclusion The fungi and algae~nuts~legumes pattern and milk-eggs patterns are inversely related to pubertal development.

Objective To understand the equity and influencing factors of maternal health service utilization in Changning District, Shanghai. Methods A convenience sampling method was used to conduct a questionnaire survey among mothers of children aged 1 to 1.5 years old who received health services from the child health care clinics and EPI clinics of 10 community health service centers in Changning District, Shanghai from March to April 2022. Count data was expressed by frequency and percentage. Chi-square analysis, binomial logistic regression analysis, and multivariate logistic regression analysis were used to analyze fairness-related factors. Rate difference, rate ratio and concentration index were used to represent fairness. Results A total of 696 subjects were investigated, with an average age of (33.35±4.76) years. There were statistically significant differences in service utilization among women with different household registrations only in early pregnancy registration (χ²=11.026, P=0.001) and postpartum visits (χ²=4.989, P=0.026). Women with a career showed differently in folic acid supplement (χ²=6.247, P=0.012), early pregnancy registration (χ²=12.989, P=0.002), physical examination in 42 days postpartum (χ²=4.446, P=0.035) and postpartum contraception (χ²=4.061, P=0.044), and the differences were statistically significant. Women with different monthly family income had a statistically significant difference in pre-pregnancy examination (χ²=8.977, P=0.030) and postpartum visit (χ²=16.114, P=0.001). There was a statistically significant difference between women with maternity insurance or not in the early pregnancy registration (χ²=10.576, P=0.001) and physical examination in 42 days postpartum (χ²=8.166, P=0.004). The results of the multivariate analysis showed that occupation (OR=2.616, 95% CI: 1.142-5.990) and maternity insurance (OR=4.490, 95% CI: 1.992~10.120) affected the utilization of service in early pregnancy registration. The monthly household income (OR=0.278, 95% CI: 0.124-0.625) affected the utilization of services in postpartum visit. At the same time, the monthly household income (10,000-19,999: OR=0.286, 95% CI: 0.090-0.907; ≥30,000: OR=0.180, 95% CI: 0.041-0.801) also affected the utilization of service in physical examination in 42 days postpartum. Conclusion The equity of maternal health care service utilization overall is good in central area in Shanghai, but there is still room for improvement. It is necessary to strengthen community mobilization, propagandize maternal health services, and expand the coverage of maternity insurance to improve the equity of maternal health service utilization and provide equal access to maternity health services.

Persistent inflammation plays a pivotal role in the initiation and progression of renal fibrosis. Activation of the pattern recognition receptor retinoic acid-inducible gene-I (RIG-I) is implicated in the initiation of inflammation. This study aimed to investigate the upstream mechanisms that regulates the activation of RIG-I and its downstream signaling pathway. Eight-week-old male C57BL/6 mice were used to establish unilateral ureteral obstruction (UUO)-induced renal fibrosis model, and the renal tissue samples were collected 14 days later for analysis. Transforming growth factor-β (TGF-β)-treated mouse renal tubular epithelial cells were used in in vitro studies. The results demonstrated that, compared to the control group, UUO kidney exhibited significant fibrosis, which was accompanied by the increases of RIG-I, p-NF-κB p65 and inflammatory cytokines, such as TNF-α and IL-1β. Additionally, the protein level of the E3 ubiquitin ligase RNF125 was significantly downregulated and predominantly localized in the renal tubular epithelial cells. Similarly, the treatment of tubular cells with TGF-β induced the increases in RIG-I, p-NF-κB p65 and inflammatory cytokines while decreasing RNF125. Co-immunoprecipitation (Co-IP) assays confirmed that RNF125 was able to interact with RIG-I. Overexpression of RNF125 promoted the ubiquitination of RIG-I, and accelerated its degradation via the ubiquitin-proteasome pathway. Overexpression of RNF125 in UUO kidneys and in vitro tubular cells effectively mitigated the inflammatory response and renal fibrosis. In summary, our results demonstrated that the decrease in RNF125 under pathological conditions led to reduction in RIG-I ubiquitination and degradation, activation of the downstream NF-κB signaling pathway and increase in inflammatory cytokine production, which promoted the progression of renal fibrosis.

In order to clarify the effects of drought stress training on the quality and drought resistance of Codonopsis pilosula, this study used PEG to simulate drought stress and employed potting with water control for the drought stress training of C. pilosula plants. The polysaccharide content, secondary metabolites, antioxidant system, and photosynthetic pigment system of C. pilosula after drought stress training were analyzed. The results showed that the content of fructans in the root of C. pilosula increased after two rounds of drought stress treatment, and it was significantly higher than that of the control group. The accumulation of fructans in the root of C. pilosula showed an upward trend during the rehydration treatment. The content of lobetyolin and tangshenoside Ⅰ increased after drought stress treatment compared with that of the control group. The rehydration treatment caused first increasing and then decreasing in the content of lobetyolin, while it had no significant effect on the tangshenoside Ⅰcontent. The content of photosynthetic pigments decreased after drought stress treatment, and it gradually increased during the first round of rehydration and the second round of rehydration. Moreover, the increase was faster in the second round of rehydration than in the first round of rehydration. The content of the peroxidation product malondialdehyde(MDA) and the activities of superoxide dismutase(SOD), peroxidase(POD), and catalase(CAT) increased after drought stress treatment compared with those of the control group, and they showed a tendency of decreasing during rehydration. Moreover, the decrease was faster in the second round of rehydration than in the first round of rehydration. When the plants of C. pilosula after drought stress training were again subjected to severe drought stress, the wilting rate decreased significantly, and the biomass increases significantly. This study showed that the drought stress training could promote the accumulation of polysaccharides and secondary metabolites in the root of C. pilosula. When encountering drought stress again, C. pilosula plants could quickly regulate the antioxidant system and delay the decomposition of chlorophyll to respond to drought stress. The findings provide a theoretical basis for the ecological cultivation of C. pilosula in arid and semi-arid areas.

Amber and subfossil resins are subjects of interdisciplinary research across multiple fields. However, due to their diverse origins and complex compositions, different disciplines vary in their definitions and functional interpretations. In traditional Chinese medicine(TCM), amber has been utilized as a medicinal material since ancient time, with extensive historical documentation. However, its classification, provenance, and nomenclature remain ambiguous, and authentic medicinal amber artifacts are exceedingly rare. This study employed Fourier-transform infrared spectroscopy(FTIR) to characterize amber and subfossil resins from various geological sources and commercially "medicinal amber". Additionally, historical literature and market surveys were analyzed to explore their provenance, composition, and functional attributes. The results indicate that amber and subfossil resins from different sources and with different compositions exhibit distinct fingerprint characteristics in the FTIR spectral range of 1 800-700 cm~(-1). "Medicinal amber" available in the market primarily consists of subfossil or modern resins, significantly differing in composition and structure from geological amber. This study highlights the importance of interdisciplinary research on amber identification and resource management. It is essential to establish a systematic database of amber and subfossil resin characteristics and integrate modern analytical techniques to enhance research on their composition, pharmacological mechanisms, and potential therapeutic effects, thereby promoting the standardized utilization of amber resources and advancing the modernization of TCM.

Cinnabar(HgS) was widely used in ancient times for medicinal purposes, religious rituals, and pigments. A group of bright red powdery clumps was excavated from Mawangdui Tomb No.3 of the Han Dynasty. Early studies considered the clumps as evidence of cinnabar's medicinal use during the Qin-Han period. This study employed a range of archaeometric techniques, including extended-depth-of-field stereo imaging, micro-CT, scanning electron microscopy-energy dispersive spectroscopy, Raman spectroscopy, and Fourier transform infrared spectrometry FTIR, to systematically analyze the material composition and structural characteristics of these remains. The results revealed that the cinnabar particles were granular, finely ground, and tightly bound to silk matrix, with no detectable excipients typically associated with medicinal formulations. Micro-CT imaging indicated a well-preserved textile structure, with clear signs of sedimentary accumulation and mechanical damage. Based on historical and archaeological studies, this study suggested that these remains were more likely degraded accumulations of cinnabar-colored silk textiles rather than medicinal cinnabar. By clarifying the diversity of ancient cinnabar applications and preservation states, this study provides new insights for the archaeological identification of mineral medicinal materials and contributes to the standardized study of Chinese medicinal materials and understanding of the historical use of cinnabar.

Objective To quantify the association between obesity and erectile dysfunction (ED) risk through a meta-analysis. Methods Following PRISMA guidelines, systematic searches of Chinese and English databases (up to March 2025) were conducted to include observational studies (cohort, cross-sectional, case-control). Adjusted effect sizes (OR and 95% CI) were extracted. Study quality was assessed using the Agency for Healthcare Research and Quality(AHRQ) scale, and a random-effects model was applied to pool effect sizes. Subgroup analyses (geographic region, obesity definitions) and sensitivity analyses were performed to validate robustness. Results Ten studies (n=230 744), including nine cross-sectional studies, were included. The meta-analysis revealed that obesity significantly increased ED risk (random-effects OR=1.80, 95% CI: 1.29-2.51), with high heterogeneity (I2=99.9%). Subgroup analyses indicated stronger associations in USA populations (OR=2.10, 95% CI: 1.23-3.60) than in Chinese populations (OR=1.16, 95% CI: 1.05-1.28). The highest effect size was observed when using BMI≥25 kg/m3 as the obesity threshold (OR=3.05, 95% CI: 2.06-4.51). Sensitivity analyses confirmed robust results (OR: 1.60-1.94 after excluding any single study). Conclusions Obesity is a critical risk factor for ED, with effect strength influenced by geographic region and obesity definitions. Interventions targeting BMI≥30 kg/m2 in Western populations and metabolic risks at BMI≥25 kg/m3 in Asian populations are recommended.

Background and aims:Hepatocellular carcinoma(HCC)is a malignant tumor with a high mortality rate,but there are still no effective treatments.The aim of this study was to investigate the anticancer po-tential of the combined use of brefeldin A(BFA)and tunicamycin(TM)in HepG2 cells,as well as the underlying mechanisms.Methods:HepG2 cells were treated with different concentrations of BFA(0.1-2.5 mg/L)and TM(1-5 mg/L)for 24 h.DMSO(0.1％,v/v)was used as a vehicle control.Cell viability and cell migration were measured using MTT assay and scratch wound assay,respectively.Apoptosis was detected using flow cytometry and acridine orange(AO)staining.The protein and mRNA levels of various factors involved in apoptosis(poly(ADP-ribose)polymerase-1(PARP-1),caspase-12,caspase-3,and stearoyl-CoA desaturase 1)and endoplasmic reticulum(ER)stress(binding immunoglobulin protein(BiP),protein kinase R-like endoplasmic reticulum kinase(PERK),p-PERK,phosphorylation of eukaryotic translation initiation factor 2alpha(p-eIF2α),activating transcription factor(ATF)4,and C/EBP homologous protein(CHOP))were measured using Western blotting and qRT-PCR,respectively.Results:Both BFA and TM alone significantly reduced the viability of HepG2 cells in a dose-dependent way.The co-incubation with TM(1 mg/L)further significantly reduced the viability of HepG2 cells treated with BFA(0.25 mg/L)alone(P＜0.05).BFA significantly increased the protein and mRNA levels of caspase-3 and PARP-1(P＜0.05)compared to control and DMSO-treated cells,indicating that BFA induced apoptosis in HepG2 cells by increasing the expression of caspase-3 and PARP-1.The induction of apoptosis by BFA could be further significantly enhanced by co-incubation with TM.In addition,BFA significantly increased the mRNA levels of BiP,PERK and ATF4(P＜0.05)compared to control and DMSO-treated cells.After co-incubation of BFA and TM,the protein levels of BiP,p-PERK,p-eIF2α and CHOP were significantly increased,indicating that TM could enhance BFA-induced ER stress in HepG2 cells through the PERK-eIF2α-ATF4-CHOP pathway.Conclusions:BFA could induce apoptosis and ER stress,and TM could enhance the ability of BFA to induce apoptosis and ER stress in HepG2 cells through the PERK-eIF2α-ATF4-CHOP pathway.The findings highlight the therapeutic potential of the combined use of BFA and TM in treating HCC.

Objective To analyze the effect of Hsa-circ-0101216 on gemcitabine(GEM)chemotherapy resistance in pancreatic cancer and its mechanism.Methods Differentially expressed circRNAs between GEM-resistant pancreatic cancer cells and parent cells were screened using the GEO database.Pancreatic cancer GEM resistant cell lines(BxPC-3-GEM and Capan-1-GEM)were constructed by intermittent concentration gradient method.qRT-PCR was used to detect the expression of Hsa-circ-0101216 in cells.GEM resistant pancreatic cancer cell lines were taken and divided into sh-circ-0101216 group(knockdown of circ-0101216),sh-NC group(transfected with sh-NC),and blank control group(untreated).CCK-8 assay and EdU proliferation assay were used to detect the half inhibitory concentration(IC50)of GEM and proliferation ability of cells in each group.Western blotting was performed to detect the expression of multidrug resistance-related protein 1(MRP1),breast cancer resistance protein(BCRP),and human equilibrative nucleoside transporter-1(hENT-1).A subcutaneous xenograft tumor model of human pancreatic cancer in nude mice was constructed,and sh-NC+GEM group and sh-circ-0101216+GEM group(n=6)were set up.The volume and weight of xenograft tumor in nude mice were compared between the two groups.Western blotting and immunohistochemistry were used to detect the expression of MRP1,BCRP,and hENT-1 proteins in xenograft tumor tissues,and EDU proliferation assay was used to detect the proliferation ability of tumor cells.Results The GEO database screening showed that Hsa-circ-0101216 was up-regulated in GEM-resistant pancreatic cancer cell lines.Pancreatic cancer GEM-resistant cell lines were successfully constructed,and the expression levels of Hsa-circ-0101216 and the IC50 value in GEM-resistant pancreatic cancer cells BxPC-3-GEM and Capan-1-GEM were significantly higher than those in parental cells(P<0.05).In sh-circ-0101216 group,the IC50 values of GEM,cell viability,EdU positivity rate,and the expression levels of MRP1 and BCRP proteins in GEM-resistant pancreatic cancer cells BxPC-3-GEM and Capan-1-GEM were significantly lower than those in blank control group and sh-NC group,while the expression level of hENT-1 protein was significantly higher(P<0.05 or P<0.001).In sh-circ-0101216+GEM group,the weight and volume of subcutaneous xenograft tumors in nude mice,the expression levels and positive expression rates of MRP1 and BCRP proteins in tumor tissues,and the EdU positive rate were significantly lower than those in sh-NC+GEM group,while the expression level and positive expression rate of hENT-1 protein were significantly higher(P<0.05).Conclusions Hsa-circ-0101216 is highly expressed in GEM-resistant pancreatic cancer cell lines.Its knockdown can inhibit the proliferation of pancreatic cancer cells and enhance the chemosensitivity of pancreatic cancer cells to GEM.The mechanism may be related to the regulation of transmembrane transporter protein expression.
