ObjectiveTo investigate the mechanism by which Shenqi Yiliu prescription reverses cisplatin resistance in ovarian cancer cells by regulating the phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway-mediated glycolysis. MethodsThe human ovarian cancer A2780 cell line was intervened with progressively increasing doses of cisplatin （1 g·L^-1） to establish the cisplatin-resistant cell line A2780cisR， and the cell sensitivity to cisplatin was examined by the cell counting kit-8 （CCK-8） assay. High， medium， and low （39.9， 19.95， 9.98 g·kg^-1） doses of Shenqi Yiliu prescription-containing sera were used to treat A2780cisR cells for 48 h. Glucose consumption and lactate production were measured by the cuvette assay. Enzyme-linked immunosorbent assay （ELISA） was employed to determine the activities of glucose transporter （GLUT）， phosphofructokinase （PFK）， and pyruvate kinase （PK）. Terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL） staining was used to detect apoptosis. Western blot was employed to quantify the protein levels of phosphorylated （p）-PI3K， p-Akt， p-mTOR， hexokinase 2 （HK2）， pyruvate kinase M2 （PKM2）， B-cell lymphoblastoma-2 （Bcl-2）， Bcl-2-associated X-protein （Bax）， and B-lymphoblastoma-2 gene-related promoter （Bad）. Real-time PCR was conducted to determine the mRNA levels of HK2， PKM2， Bax， Bcl-2， and Bad. ResultsThe median inhibitory concentration （IC₅₀） of cisplatin on A2780cisR cells was nearly 3 times that on A2780P cells. Compared with A2780P cells， A2780cisR cells showed increased glucose consumption， lactate production， GLUT， PFK， and PK activities， and mRNA and protein levels of p-PI3K， Akt， p-mTOR， HK2， PKM2， Bax （P<0.05）， and decreased apoptosis rate and Bcl-2 expression （P<0.05）. Compared with A2780cisR cells， medium- and high-dose Shenqi Yiliu prescription reduced the glucose consumption， lactate production， GLUT， PFK， and PK activities， and mRNA and protein levels of p-PI3K， Akt， p-mTOR， HK2， PKM2， Bax， and Bad （P<0.05）， while increasing the apoptosis rate and Bcl-2 expression （P<0.05）. ConclusionShenqi Yiliu prescription can inhibit glycolysis mediated by the PI3K/Akt/mTOR pathway to promote apoptosis， thereby reversing cisplatin resistance in ovarian cancer cells.

BACKGROUND:Titanium elastic intramedullary nailing for the treatment of significantly displaced midshaft clavicle fractures has the characteristics of minimally invasive and elastic fixation.The displacement of the fracture is closely related to the later function.However,there are few studies on the three-dimensional displacement analysis of the fracture ends before surgery and after intramedullary fixation such as titanium elastic intramedullary nailing.OBJECTIVE:To explore the three-dimensional displacement of fracture ends after midshaft clavicle fracture and fixation with titanium elastic intramedullary nails,and to analyze the risk factors.METHODS:A total of 91 patients with midshaft clavicle fracture(fracture end shortening ≥15 mm)admitted to Wendeng Orthopedic Hospital of Shandong Province from April 2019 to April 2024 were selected,including 57 males and 34 females,aged(51.73±10.21)years old.All patients received closed reduction and internal fixation with titanium elastic intramedullary nail.CT scans of the affected clavicle were performed before and on the first day after surgery.The CT data were imported into Mimics software for modeling.The length of the clavicle,lateral displacement of the fracture end,and rotation of the distal end of the fracture along the X,Y,and Z axes were measured and recorded before and after surgery.Pearson correlation coefficient was used for correlation analysis of various parameters,and generalized linear regression was used to evaluate risk factors.RESULTS AND CONCLUSION:(1)Preoperatively,the variable that increased the risk of lateral displacement was the number of comminuted bone fragments,the variable that increased the risk of shortening displacement was male patients,and the variable that increased the risk of Z-axis rotation was the left limb.Shortening displacement was significantly positively correlated with lateral displacement(r=0.715,P＜0.001);shortening displacement was significantly positively correlated with X-axis rotation displacement and Y-axis rotation displacement(r=0.265,P=0.028;r=0.303,P=0.011);lateral displacement was significantly positively correlated with Y-axis rotation and Z-axis rotation(r=0.258,P=0.032;r=0.250,P=0.038);X-axis rotation was significantly positively correlated with Y-axis rotation(r=0.382,P=0.001),and Z-axis rotation was significantly positively correlated with Y-axis rotation(r=0.280,P=0.020).(2)Postoperatively:The number of scapula fractures and comminuted bone fragments were variables that increased the risk of postoperative shortening and lateral displacement:Preoperative X-,Y-,and Z-axis rotation displacements were risk variables that increased postoperative X-,Y-,and Z-axis rotation displacements,respectively.Postoperative lateral displacement was significantly positively correlated with postoperative shortening and displacement(r=0.584,P=0.000),and postoperative lateral displacement was also significantly positively correlated with postoperative Y axis rotation and Z axis rotation(r=0.360,P=0.002;r=0.250,P=0.038).Postoperative Y axis rotation was significantly positively correlated with postoperative Z axis rotation(r=0.248,P=0.040).(3)The results showed that the three-dimensional displacement of the clavicle end before and after surgery was affected by many factors,especially the number of comminuted bone fragments,scapula fractures,gender,and original rotation displacement.At the same time,there were complex correlations between various displacements,especially the correlation between shortening displacement and lateral displacement was the strongest.

Objective To analyze the epidemiological characteristics and disease burden of malignant tumors in Shijiazhuang in 2021. Methods Based on data from the Shijiazhuang City Cancer Registry, incidence and mortality indicators for malignant tumors were calculated, including crude rates, age-standardized rates (using Chinese and world standard populations), and the cumulative rate (0−74 years old), to describe the epidemiological profile. The disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) were calculated to estimate the disease burden of malignant tumors. Results In 2021, a total of 13250 new cancer cases were recorded. The crude incidence rate was 275.50/10⁵, the ASR China was 177.17/10⁵, the ASR world was 172.11/10⁵, and the cumulative rate (0–74 years old) was17.77%. The age-specific incidence of malignant tumors reached its peak in the age group of 80–84 years old. A total of 7165 deaths were noted, and the crude mortality rate was 148.98/10⁵. The ASR China was 85.13/10⁵, the ASR world was 84.52/10⁵, and the cumulative rate (0–74 years old) was 9.49%. The age-specific mortality of malignant tumors reached its peak in the age group of above 85 years old. Lung cancer and breast cancer were the most common malignant tumors in males and females. The DALYs of malignant tumors were 87725.29 person-years, and the DALY rate was 18.24‰. YLL was 85392.09 person-years (97.34%), and YLD was 2333.19 person-years (2.66%). Lung cancer had the heaviest disease burden with DALY of 22687.12 person-years, accounting for 25.86% of all malignant tumors, followed by gastric, liver, colorectal and esophageal cancers. Conclusion Cancers of the lung, liver, female breast, stomach, and colorectum are the major health threats in Shijiazhuang. Malignant tumor brings heavy burden to residents of Shijiazhuang city. To decrease the disease burden of cancer, scholars should pay more attention, and implement preventive measures early.

OBJECTIVE: To investigate the current status of clinical genetics specialization development and the diagnostic and therapeutic capabilities for hereditary diseases across medical institutions in Shanghai, and to assess the necessity and feasibility of establishing training bases for clinical genetics specialists. METHODS: By employing a cross-sectional survey design, the Clinical Genetics Committee of Shanghai Medical Association has conducted questionnaire surveys from March to April 2025 across 54 healthcare institutions in Shanghai (including 33 tertiary hospitals and 21 secondary hospitals). The survey involved administrative departments and medical personnel from 15 clinical specialties. The survey has covered current genetic disease diagnosis and treatment practices, relevant and specialised disease types, genetic department establishment, testing capabilities, personnel teams, and training requirements. RESULTS: The results revealed that 78.0% of clinical departments surveyed had treated patients with hereditary disorders. Shanghai possesses diagnostic and therapeutic expertise for over 95% of hereditary diseases listed in its rare disease catalogue, reflecting both the practical clinical demand for such conditions and the city's overall diagnostic and therapeutic strengths in this field. Nevertheless, significant disparities exist in the development of genetics departments across different tiers of healthcare institutions. Resources for genetic testing capabilities (including molecular, cellular, and biochemical testing) are also unevenly distributed across different tiers of hospitals. The survey further revealed that only 26.0% of departments believe that their current physician structure fully meets the diagnostic and treatment demands. Over 90% of departments consider standard training for clinical genetic specialists necessary, with 74.0% expressing willingness to participate in establishing training bases. Based on above findings and thorough deliberation, the Clinical Genetics Committee of the Shanghai Medical Association proposes advancing specialist training and discipline development through establishing a standard training system. The committee has drafted a three-year training protocol featuring a "joint training"-centered model, recommending a pilot-first, dynamically optimized strategy for steadily advancing training base development. CONCLUSION Shanghai faces substantial demand for genetic disease diagnosis and treatment, yet exhibits shortcomings in clinical genetics specialization development, resource allocation, and talent pipeline cultivation. To establish a standard training system holds significant practical importance and is underpinned by a broad demand.

Obesity and its related metabolic diseases have become a major global public health threat, and its rising incidence significantly increases the risk of cardiovascular and cerebrovascular diseases, diabetes and other complications. Pancreatic lipase is a key enzyme that converts food-borne lipids into triglycerides and fatty acids, and the effective inhibition of its activity has become an important strategy for the treatment of obesity. This paper discusses the screening methods of pancreatic lipase inhibitors, and summarizes and reviews the basic principles, advantages and disadvantages and application status of traditional screening methods, modern new screening methods and virtual screening methods. In view of the problems faced by the screening methods of pancreatic lipase inhibitors, future research urgently needs to move towards a collaborative innovation path of multi-technology integration, intelligent screening and complex systematization of traditional Chinese medicine, so as to open up new research paradigms.

AIM: To investigate the correlation between different severity grades of obstructive sleep apnea-hypopnea syndrome(OSAHS)and visual field defects as well asvisual evoked potential(VEP)parameters in patients with anterior ischemic optic neuropathy(AION). METHODS: A retrospective case-control study. Patients diagnosed with AION complicated by OSAHS at the Department of Ophthalmology, the Affiliated Xuzhou Municipal Hospital of Xuzhou Medical University, between June 2022 and October 2025 were selected as the study subjects. According to the AHI and mSaO2, the patients were divided into three groups: a mild group(AHI 5-15 events/h, mSaO2 85%-90%), moderate group(AHI 16-30 events/h, mSaO2 80%-85%), and severe group(AHI >30 events/h, mSaO2 <80%). General demographic data, retinal nerve fiber layer(RNFL)thickness, visual field defect indicators including mean defect(MD)and pattern standard deviation(PSD), as well as VEP parameters(P100 latency and amplitude)were compared among the three groups. RESULTS: This study included a total of 110 patients with AION complicated by OSAHS. Based on the severity of OSAHS, the patients were divided into a mild group of 37 patients(21 men and 16 women, mean age 62.15±9.37 y), a moderate group of 35 patients(20 men, 15 women; mean age 61.82±8.94 y), and a severe group of 38 patients(22 men, 16 women; mean age 63.02±9.61 y). There were no significant differences among the three groups in terms of age, sex, TG, TC, LDL-C, HDL-C levels, or AION severity(all P>0.05); however, there were significant differences in history of hypertension, history of diabetes, systolic blood pressure, diastolic blood pressure, and FPG levels(all P<0.05). The mean RNFL thickness in the severe group(63.27±5.58 μm)was significantly lower than that in the moderate group(74.14±6.28 μm)and the mild group(83.22±7.02 μm), and the moderate group was lower than the mild group(all P<0.05); The MD value(-11.57±1.82 dB)and PSD value(7.35±0.87 dB)in the severe group were both higher than those in the moderate group [(-7.62±1.31 dB),(4.89±0.62 dB)] and the mild group [(-4.38±1.05 dB),(2.57±0.45 dB)](all P<0.05); the P100 latency in the severe group(132.41±8.57 ms)was longer than that in the moderate group(118.75±7.32 ms)and the mild group(105.62±6.14 ms), and the amplitude(7.65±1.53 μV)was lower than that of the moderate group(11.24±1.89 μV)and the mild group(15.38±2.11 μV)(all P<0.05). Spearman's correlation analysis revealed that the severity of OSAHS was negatively correlated with the MD value(rs=-0.901, P<0.05)and positively correlated with the PSD value and P100 latency(rs=0.947, 0.807, P<0.05), and was negatively correlated with P100 amplitude(rs=-0.878, P<0.05). CONCLUSION:The severity of OSAHS is closely associated with RNFL thickness, visual field defects, and VEP parameters in patients with AION; the more severe the OSAHS, the more pronounced the structural and functional damage to the optic nerve. Monitoring AHI and mSaO2 can aid in assessing the condition of patients with AION and developing personalized intervention plans.

Autotransplantation of teeth (ATT) is a surgical technique that involves transplanting a non-functional tooth (donor tooth) within the oral cavity to an edentulous area (recipient site). This procedure not only demonstrates reliable long-term success and survival rates but also possesses unique osteoinductive capacity and soft tissue preservation advantages, making it particularly suitable for the restoration of dental defects in adolescents. However, ATT is highly technique-sensitive, and its successful implementation depends on the operator’s comprehensive mastery of multidisciplinary knowledge, including alveolar surgery, periodontology, endodontics, prosthodontics, and orthodontics, as well as the precise design and execution of personalized surgical plans. Preoperative systematic evaluation is required to assess the root development stage of the donor tooth, the bone volume condition of the recipient site, and the compatibility between the donor tooth and the recipient site. For teeth with an open apex, pulpal healing through revascularization is often achievable with a high success rate, whereas those with a closed apex typically require root canal treatment 2-4 weeks postoperatively to minimize complications. Utilizing cone beam computed tomography, intraoral scanning, and virtual surgical planning enables accurate assessment of donor-recipient matching and the design of the transplantation plan. Intraoperatively, careful attention must be paid to minimizing tissue trauma through precise planning and gentle manipulation, strictly limiting the extra-oral time of the donor tooth to within 15 min, and maintaining the root surface moist at all times to protect the periodontal ligament and improve surgical outcomes. The application of tools, such as 3D-printed personalized surgical guides, donor tooth replicas, and customized osteotomes, has enhanced the precision of socket preparation. Further, emerging technologies, such as dynamic navigation, surgical robotics, and artificial intelligence, have also demonstrated promising potential in the field of ATT.

Objective To investigate the mechanism of autophagy induced by House dust mites(HDM)on airway epithelial tight junction through β-catenin-Snail signaling pathway.Methods Human bronchial epithelial cells(16HBE)were stimulated with HDM at different time points(0,3,6,12,24,48 h)and different concen-trations(0,40,100,200 μg/mL)to screen the appropriate stimulation concentration and stimulation time.16HBE cells were treated with oxidative stress inhibitor N-acetylcysteine(NAC),autophagy inhibitor 3-methylad-enine(3-MA),HDM,and their combinations.Cells were transfected with mCherry-EGFP-LC3B,Beclin-1-siRNA,and ATG14-siRNA lentivirus and then stimulated with NAC and HDM.Immunofluorescence was used to detect the expression levels of autophagy-related protein LC3B,tight junction-related proteins Occludin,and ZO-1 in airway epithelial cells.The level of reactive oxygen species(ROS)was detected by using DCFH-DA in each group.The protein expression levels of Occludin,ZO-1,LC3B,Beclin-1,ATG5,ATG14,P62,Snail,β-catenin and p-β-catenin were detected by Western blot method.Results Immunofluorescence results showed that compared with the control group,200 μg/mL HDM stimulation induced cellular autophagy,increased the expression level of LC3B protein,and promoted the level of ROS,all with statistical significances(all P<0.05).Compared with the HDM group,the HDM+3-MA,HDM+ATG14-si,and HDM+Beclin-1-si groupsall showed significantincreases in the expression levels of tight junction-related proteins Occludin and ZO-1(P<0.05).The HDM+NAC group demonstrated significant decreases both in the level of ROS andin the expression level of LC3B protein.Western blot results revealed that compared with HDM,3-MA and autophagy protein low-expression beads(Beclin-1-si,ATG14-si)attenuated HDM-induced cellular autophagy(P<0.05),inhibited HDM-induced upregulation of Snail and p-β-catenin expression,and improved HDM-induced decreases in Occludin and ZO-1(P<0.05).Moreover,compared with the HDM group,the NAC+HDM group exhibited significant decreases both in the conversion of LC3BⅠ to LC3BⅡ(P<0.001)in the protein levels of Snail,p-β-catenin,Beclin-1 and ATG14(P<0.01),but significant increases in the protein levels of Occludin and ZO-1(P<0.05).Conclusion HDM affects the tight connections between airway epithelial cells by inducing autophagy,which may be attributed to the β-catenin-Snail signaling pathway.

Aim To investigate the effect of tetrameth-ylpyrazine(TMP)on neuroinflammation after cerebral ischemia and hypoxia via mannose-binding lectin(MBL).Methods Patients diagnosed with ischaemic stroke at Shanxi Provincial People's Hospital were in-cluded in the study,and their clinicopathological data,as well as blood and urine samples,were collected with the consent of the patients and their families.Using these biological samples,differential proteins and tar-gets were identified by proteomic analysis and subse-quently verified with animal experiments.The mice were divided into the sham,dMCAO,and TMP(10,20,40 mg·kg-1)treatment groups.After seven days of drug administration,the modified neurological sever-ity score(mNSS)was used to assess the neurological function.TTC staining was used to detect the volume of cerebral infarction.Motor function was evaluated be-haviourally,and ELISA was used to detect MASP1,sC5b-9,TNF-α,IL-6,and IL-1β.Western blot was used to determine the expression of relevant proteins,such as MBL2,MASP2,and C3.Results Compared with the sham group,the dMCAO group exhibited in-creased neurological impairment,which was signifi-cantly ameliorated by TMP treatment.The expression levels of MBL2,C3 and MASP2 were elevated in the dMCAO group and were reduced following TMP treat-ment.Additionally,the dMCAO group showed elevat-ed expression of inflammatory factors IL-1 β,IL-6 and TNF-α,which were then suppressed by TMP treat-ment.Conclusion TMP inhibits the inflammatory re-sponse after ischemia and hypoxia by regulating MBL,thus attenuating brain injury.
