By reviewing the physical biological research on the activation of acupoint effects by acupuncture， this paper explains the activation mechanism from the perspective of the generation and transmission of mechanical signals caused by acupuncture， and reveals the physical-chemical coupling processes in the acupoint microenvironment. Future research should focus on locally mechanosensitive cells， further exploring how acupuncture mechanical signals trigger dynamic changes in cells and molecules in the acupoints， and the physical-chemical information transduction mechanism， which will provide scientific evidence for the acupoint activation during acupuncture. Related studies will contribute to a deeper understanding of the scientific principles behind acupuncture and promote its clinical application and development.

Objective:To investigate the relationship between protein tyrosine phosphatase non-receptor type 1 (PTPN1) gene polymorphism and the risk of gestational diabetes mellitus (GDM).Methods:In this case-control study, 4 835 pregnant women who delivered from March, 2012 to July, 2014 in the Department of Gynecology and Obstetrics at the First Hospital of Shanxi Medical University were consecutively enrolled. Among them, 789 cases were diagnosed with GDM. A simple random sampling method was used to select 334 pregnant women with GDM as the case group, and 334 healthy pregnant women matched by maternal age, gestation time and residence were set as control. The DNA genotyping was performed in the subjects, and those with genotyping deletions10% were excluded; and finally, 322 and 317 subjects were included in case and control group, respectively. Under the codominant, dominant, recessive, and allelic genetic models, the unconditional logistic regression model was used to check the relationship between 13 candidate single nucleotide polymorphism (snp) loci in PTPN1 gene and the risk of GDM. The Haploview was used to analyze the relationship between haplotypes and risk of GDM, and multiple comparisons were adjusted with the false discovery rate (FDR) method.Results:The age of the 639 pregnant women analyzed in this study was (30.28±4.32) years. The proportions of pre-pregnancy body mass index (BMI)≥24.0 kg/m 2 and having a family history of diabetes were significantly higher in the GDM group compared to those in the control group (29.19% vs 16.72% and 13.04% vs 6.31%, respectively, both P0.05). The rs6096644 locus was positively associated with increased risk of GDM in co-dominant (GG vs AA, OR=2.76, 95% CI: 1.18-6.44) and recessive (GG vs AA+AG, OR=2.78, 95% CI: 1.20-6.46) genetic models (all q0.2). The rs6096655 locus was positively associated with increased risk of GDM in codominant (AA vs GG, OR=5.90, 95% CI: 1.27-27.36) and recessive (AA vs GG+GA, OR=5.50, 95% CI: 1.19-25.38) and alleles (A vs G, OR=1.51, 95% CI: 1.09-2.08) genetic models (all q0.2). The rs6013317 locus was associated with an increased risk of GDM in the allele (A vs G, OR=1.74, 95% CI: 1.15-2.63) genetic model (all q0.2). The GAGG haplotype and GGAG haplotype in haplotype block 1 (rs4811262, rs6096646, rs6096655, rs6013317), and the GGGA haplotype in haplotype block 2 (rs6068018, rs6123105, rs6013324, rs2869621) of the PTPN1 gene were all positively associated with an increased risk of GDM (all P0.05). Conclusion:PTPN1 gene polymorphisms may associated with risk of GDM, moreover, complex haplotype structures within the gene influence the risk of GDM.

A 67-year-old male had undergone bilateral lung transplantation for chronic obstructive pulmonary disease 11 months before the current presentation. He was admitted with a 5-day history of cough with sputum, and a 2-day history of fever. Computed tomography (CT) of the chest revealed rapidly progressive bilateral diffuse "ground glass" opacities. Despite anti-infective therapy and methylprednisolone pulse therapy, his condition deteriorated, necessitating endotracheal intubation with mechanical ventilation and veno-venous extracorporeal membrane oxygenation (V-V ECMO) for life support. A bedside cryobiopsy was undertaken, with pathology confirming the organizing pneumonia diagnosis. Comprehensive treatment was continued: methylprednisolone, tacrolimus for immunosuppression, and prophylactic anti-infectives. His partial pressure of oxygen in the blood by the fraction of inspired oxygen ratio and imaging findings improved gradually. ECMO support was discontinued after 2 weeks, and he was discharged 1-month later, resuming normal daily activities. At 2-month follow-up, he exhibited improved exercise tolerance. Chest CT showed bilateral upper-lobe emphysema (predominantly upper-lobe reticular shadows) and significant bilateral upper-lobe pleural thickening. After 12 months of fllow-up, a diagnosis of chronic lung allograft dysfunction was made based on imaging findings and the trajectory of pulmonary function.

Objective To establish a pediatric rare disease catalog,analyze the current status of therapeutic drugs and their coverage of the medical insurance in China,and propose strategies to enhance drug accessibility.Methods Pediatric rare diseases were identified from China's two national rare disease catalogs combined with the EU Orphanet database,US FDA orphan drug database,and the Diagnosis and Treatment Standards for Rare Diseases in Children.We created a specialized drug catalog for pediatric rare diseases,then analyzed drug types(ATC classification),pricing,and medical insurance coverage using descriptive statistics based on Yaozhi.com drug bidding prices and the 2024 Drug of List National Basic Medical Insurance(NBMIDL).Drug affordability was assessed through annual treatment cost calculations.Results The national catalogs included 151 pediatric rare diseases(72.95%of listed conditions),spanning 13 disease systems.We identified 94 dedicated orphan drugs(by generic name)for these conditions,among which 43 were approved internationally but unavailable in China.The average unit price per package was 6 113.53 yuan.Overall NBMIDL coverage was 68.83%,but drugs priced above 7 000 yuan per unit had only 7.69%coverage.Annual treatment costs reached 4.54 million for laronidase(mucopolysaccharidosis).Conclusions Critical gaps persist in China's pediatric rare disease treatment landscape,including catalog deficiencies,inadequate coverage for high-cost drugs and insufficient domestic innovation.It is recommended to establish a list of orphan drugs for pediatric rare diseases,accelerate the import of foreign drugs and the local innovative drugs through policy incentives,optimizing medical insurance reimbursement mechanisms for pediatric rare disease drugs to comprehensively improve therapeutic accessibility.

Objective:To investigate the effects of soybean isoflavones(SIF)on immune function of rats with ulcerative colitis(UC)by regulating high-mobility group protein B1(HMGB1)/receptor for advanced glycation end products(RAGE)signal pathway.Methods:Sixty SD rats were randomly grouped into Model group,low dose SIF group(SIF-L group,300 mg/kg SIF),high dose SIF group(SIF-H group,450 mg/kg SIF),high dose SIF+HMGB1 inhibitor glycyrrhizic acid group(SIF-H+glycyrrhizic acid group,450 mg/kg SIF+30 mg/kg glycyrrhizic acid)and Control group,with 12 rats in each group.The UC rat model was established by TNBS/ethanol combined enema.Body weight changes of rats in each group were measured,and disease activity index(DAI)was determined in each group.Histopathological changes of colon were observed by HE staining;levels of superoxide dismutase(SOD)and malondial-dehyde(MDA)in colon tissue of rats were measured by colorimetry;serum levels of IL-1β,TNF-α and IL-4 were determined by ELISA;flow cytometry was used to determine the percentages of CD3+T,CD4+T and CD8+T lymphocytes in peripheral blood mononuclear cells;levels of serum IgA and IgG were measured by automatic specific protein analyzer;expressions of HMGB1 and RAGE in colon tissues were determined by Western blot and immunohistochemistry.Results:Compared with Control group,levels of DAI,serum TNF-α,IL-1β,IgA,IgG,MDA in colon tissue,HMGB1 and RAGE protein expressions in colon tissue of Model group were obviously higher(P<0.05),while SOD level,IL-4,CD3+T,CD4+T and CD8+T lymphocyte percentages,CD4+/CD8+T were obviously lower(P<0.05),the mucosa of colon tissue was damaged.Compared with Model group,changes of relevant indexes in SIF-H group were contrary to the above(P<0.05),and the damage of colon tissue was alleviated.Conclusion:SIF may enhance the immune function of UC rats by inhibiting HMGB1/RAGE signal pathway.

Objective:To study the risk factors of unplanned reoperation within 30 days after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 207 patients who underwent LPD in the Lihuili Hospital Affiliated to Ningbo University from February 2017 to October 2022 were retrospectively analyzed. There were enrolled 118 males and 89 females, aged (65.1±11.1) years old. Patients were divided into the reoperation group ( n=15) and non-reoperation group ( n=192) based on whether unplanned reoperation was performed within 30 days after LPD. The risk factors of unplanned reoperation were analyzed with univariate and multivariate logistic regression analysis. Results:The rate of unplanned reoperation within 30 days after LPD was 7.2%(15/207). The unplanned reoperation group exhibited a higher incidence of complications 80% (12/15), mortality 13.3% (2/15), and extended hospital stay (32.9±20.1)d compared to the non-reoperation group, which incidences of complications, mortality and extended hospital stay were 40.1% (77/192)( χ2=9.04, P=0.003), 0.5%(1/192)( χ2=8.28, P=0.004), and (17.9±8.6)d ( t=-2.79, P=0.014), respectively. Unplanned reoperation was associated with diabetes, intraoperative bleeding >130 ml, preoperative serum prealbumin <0.15 g/L, pancreatic texture and pancreatic duct diameter (all P<0.05). Multivariate logistic regression analysis identified diabetes ( OR=4.991, 95% CI: 1.431-17.415), preoperative serum prealbumin <0.15 g/L ( OR=4.06, 95% CI: 1.178-14.043), soft pancreatic texture ( OR=3.900, 95% CI: 1.146-13.272) and pancreatic duct diameter ≤3 mm ( OR=3.449, 95% CI: 1.009-11.789) as independent risk factors for unplanned reoperation within 30 days. Conclusion:Preoperative diabetes, preoperative serum prealbumin levels <0.15 g/L, soft pancreatic texture and pancreatic duct diameter ≤3 mm were independent risk factors for unplanned reoperation within 30 days after LPD.
