ObjectiveTo investigate the influencing factors for traditional Chinese medicine （TCM） syndromes in pancreatic cancer by analyzing 608 cases， and to provide a theoretical reference for TCM syndrome differentiation and standardized treatment of pancreatic cancer. MethodsA total of 608 patients with a pathological or clinical diagnosis of pancreatic cancer who were admitted to Shanxi Institute of Traditional Chinese Medicine， The Affiliated Hospital of Shanxi University of Chinese Medicine， and Shanxi Provincial Hospital of Integrated Traditional Chinese and Western Medicine from January 2019 to December 2023 were enrolled， and TCM syndrome differentiation was performed. The chi-square test was used for comparison of categorical data between groups. The clinical data with statistical significance between groups were included in the regression analysis， and the unordered polytomous logistic regression model was used to investigate the influencing factors for the TCM syndrome of pancreatic cancer. ResultsFor the 608 patients with pancreatic cancer， common initial symptoms included abdominal pain （32.40%）， abdominal distension （23.85%）， fatigue （16.12%）， and emaciation （10.03%）， and the main clinical symptoms included poor appetite （75.97%）， abdominal pain （67.27%）， fatigue （61.84%）， abdominal distension （57.40%）， and emaciation （53.62%）. There were significant differences between the patients with different TCM syndromes of pancreatic cancer in sex （χ²=62.823， P<0.001）， disease duration （χ²=14.868， P=0.011）， clinical stage （χ²=21.006， P<0.001）， lymph node metastasis （χ²=2.205， P=0.032）， surgery （χ²=38.008， P<0.001）， chemotherapy （χ²=21.384， P<0.001）， radiotherapy （χ²=17.510， P=0.004）， and immunotherapy （χ²=18.573， P=0.002）. The logistic regression analysis showed that male sex was a protective factor against Qi and blood deficiency syndrome （odds ratio ［OR］=0.081， 95% confidence interval ［CI］： 0.031‍ ‍—‍ ‍0.213， P<0.001）， Qi stagnation and blood stasis syndrome （OR=0.100， 95%CI： 0.041‍ ‍—‍ ‍0.247， P<0.001）， and syndrome of Yin deficiency with internal heat （OR=0.158， 95%CI： 0.057‍ ‍—‍ ‍0.444， P<0.001）， while it was a risk factor for the syndrome of damp-heat accumulation （OR=2.378， 95%CI： 1.074‍ ‍—‍ ‍5.266， P=0.033）； the course of the disease of<1 year was a protective factor against Qi and blood deficiency syndrome （OR=0.167， 95%CI： 0.073‍ ‍—‍ ‍0.383， P<0.001）， syndrome of spleen-kidney Yang deficiency （OR=0.183， 95%CI： 0.089‍ ‍—‍ ‍0.378， P<0.001）， and syndrome of Yin deficiency and internal heat （OR=0.164， 95%CI： 0.070‍ ‍—‍ ‍0.385， P<0.001）； clinical stage Ⅰ/Ⅱ/Ⅲ was a risk factor for damp-heat accumulation （OR=2.793， 95%CI： 1.259‍ ‍—‍ ‍6.196， P=0.012） and Qi stagnation and blood stasis syndrome （OR=7.863， 95%CI： 2.808‍ ‍—‍ ‍22.020， P<0.001）； lymph node metastasis was a risk factor for Qi and blood deficiency syndrome （OR=4.005， 95%CI： 1.477‍ ‍—‍ ‍10.861， P=0.006）； surgical treatment was a risk factor for Qi and blood deficiency syndrome （OR=4.151， 95%CI： 1.916‍ ‍—‍ ‍8.995， P<0.001）， syndrome of spleen-kidney yang deficiency （OR=5.352， 95%CI： 2.436‍ ‍—‍ ‍11.759， P<0.001）， Qi stagnation and blood stasis syndrome （OR=2.334， 95%CI： 1.071‍ ‍—‍ ‍5.088， P=0.033）， and syndrome of Yin deficiency and internal heat （OR=4.167， 95%CI： 1.789‍ ‍—‍ ‍9.707， P<0.001）； chemotherapy was a protective factor against damp-heat accumulation （OR=0.188， 95%CI： 0.082‍ ‍—‍ ‍0.428， P<0.001）； radiotherapy was a risk factor for damp-heat accumulation （OR=2.571， 95%CI： 1.151‍ ‍—‍ ‍5.746， P=0.021） and syndrome of Yin deficiency with internal heat （OR=8.384， 95%CI： 3.348‍ ‍—‍ ‍20.997， P<0.001）； immunotherapy was a risk factor for Qi and blood deficiency syndrome （OR=2.114， 95%CI： 1.021‍ ‍—‍ ‍4.379， P=0.044）. ConclusionSex， course of the disease， clinical stage， presence or absence of lymph node metastasis， surgery， chemotherapy， radiotherapy， and immunotherapy are the main influencing factors for the TCM syndrome of pancreatic cancer.

Tubal ciliary movement is one of the essential transport mechanisms for female fertility, playing a key role in facilitating oocyte pickup and transporting the fertilized ovum. This movement is mediated by multiciliated cells and regulated by specific proteins and hormones that modulate ciliary number, length, polarity, beat frequency, and amplitude to ensure proper function. Genetic mutations, inflammatory stimuli, and hormonal fluctuations can impair ciliary activity or induce ciliary apoptosis, leading to ciliary dysfunction. Disorders of tubal ciliary movement are frequently observed in primary ciliary dyskinesia, pelvic inflammatory disease, polycystic ovary syndrome, and endometriosis, conditions commonly associated with female infertility. These disorders manifest as structural abnormalities of cilia, disrupted polarity, shortened ciliary length, reduced ciliary count, and decreased beat frequency and amplitude. Understanding the role of tubal ciliary movement in female infertility-related diseases, through immunohistochemistry and ultrastructural analysis, helps clarify underlying infertility mechanisms. Identifying abnormal inflammatory factors, hormonal environments, and gene expression, combined with advanced techniques for measuring ciliary protein and beat frequency, may offer novel clinical targets for early prevention and treatment of female infertility.

The αPD-L1 antibody-based immune checkpoint blockade therapy is still limited by the poor clinical response rate as it is mainly utilized to block surface PD-L1 on tumor cells while ignoring abundant PD-L1 exosomes secreted in the environment, causing tumor immune evasion. Here, we proposed an exosome biogenesis inhibition strategy to suppress tumor exosomes secretion from the source, reducing the inhibitory effect on T cells and enhancing chemo-immunotherapy efficacy. We developed sulfafurazole homodimers (SAS) with disulfide linkages, effectively releasing the drug in response to glutathione (GSH) and inhibiting 4T1 tumor-derived exosomes secretion. Subsequently, gemcitabine (Gem) was encapsulated to induce immunogenic cell death (ICD). Consequently, Gem@SAS inhibited the secretion of tumor exosomes by more than 70%, increased proliferation and granzyme B secretion ability of T cells by more than 2 times, and showed superior efficacy in breast cancer treatment as well as lung metastasis of breast cancer.

Gene therapy, harnessing the power of CRISPR-Cas9 and/or DNAzyme systems, stands as a pivotal approach in cancer therapy, enabling the meticulous manipulation of genes pivotal to tumorigenesis and immunity. However, the pursuit of precise gene therapy encounters formidable hurdles. Herein, a near-infrared upconversion theranostic nanomachine is devised and tailors for CRISPR-Cas9/DNAzyme systems mediate precise gene therapy. An ingenious logic DNAzyme system consists of Chain 1 (C1)/Chain 2 (C2) and endogenous lncRNA is designed. We employ manganese modified upconversion nanoparticles for carrying ultraviolet-responsive C1-PC linker-C2 (C₂P) chain and Cas9 ribonucleoprotein (RNP), with outermost coats with hyaluronic acid. Upon reaching tumor microenvironment (TME), the released Mn²⁺ ions orchestrate a trifecta: facilitating endosomal escape, activating cGAS-STING signaling, and enabling T1-magnetic resonance imaging. Under near-infrared irradiation, Cas9 RNP/C₂P complex dissociates, releasing Cas9 RNP into the nucleus to perform gene editing of Ptpn2, while C1/C2 chains self-assemble with endogenous lncRNA to form a functional DNAzyme system, targeting PD-L1 mRNA for gene silencing. This strategy remodels the TME by activating cGAS-STING signaling and dual immune checkpoints blockade, thus realizing tumor elimination. Our theranostic nanomachine armed with the CRISPR-Cas9/DNAzyme logic systems, represents a resourceful and promising strategy for advancing cancer systemic immunotherapy and precise gene therapy.

Objective:To analyze the effects of changes in the spectrum of deaths from malignant tumors on the life expectancies of residents of different ages, sexes, and regions (urban or rural) in Tianjin from 1999 to 2019.Methods:The Abridged Life Table method and the Arriaga's decomposition method were used to calculate the effects of changes in spectrum of deaths from malignant tumors on the life expectancies of Tianjin residents of different ages, sexes, and regions.Results:During 1999-2019, the life expectancies increased by 4.96 years and 5.69 years for males and females, respectively, in Tianjin. The decreases in the mortalities from malignant neoplasms contributed 0.12 year (3.30%) and 0.03 year (0.77%) for males and females, respectively, to the increase during 1999-2007, and 0.05 year (3.13%) and 0.12 year (6.08%) for males and females, respectively, during 2007-2019. The decreases in the mortality rates of malignant tumors contributed the most to the increase among residents in the 60-69 years group, and the decreases in mortality rates of lung, gastric, esophageal, and liver cancers had relatively larger contribution. Lung cancer had a negative effect on the life expectancies of men and rural residents, but a positive effect on those of women and urban residents. The significant increases in the mortality rates of lung, colorectal, and pancreatic cancers in the ≥85 years group had a large negative effect on the overall life expectancy. Breast and ovarian cancers contributed negatively to the life expectancy of female residents.Conclusion:The overall increase in the life expectancy in Tianjin from 1999 to 2019 was mainly attributed to the elderly and the decreases in the mortality rates of gastric, esophageal, and liver cancers, among other malignancies, while the increases in the mortality rates of lung, colorectal, gallbladder, pancreatic, and breast cancers were the most significant factors hindering the increase of the life expectancy in Tianjin.

Objective To investigate the effect of continuous intraoperative insulin infusion on my-ocardial blood perfusion after cardiac surgery under cardiopulmonary bypass(CPB).Methods Forty-eight patients,21 males and 27 females,aged 55-80 years,BMI 18-28 kg/m2,ASA physical status Ⅱ-Ⅳ,who underwent elective cardiac surgery with CPB were selected and randomly divided into two groups:the insulin group(group I,n = 25)and the control group(group C,n = 23).The same anesthesia protocol was implemented in both groups.After induction of anesthesia,group Ⅰ received intravenously infusion of in-sulin 30 mU·kg-1·h-1,glucose 0.12 g·kg-1·h-1,and potassium chloride 0.06 mmol·kg-1·h-1,and group C received saline 10 ml/h,all of which were infused until the end of surgery.The targeted blood glucose range for both groups was set at 6.1-11.1 mmol/L.Transesophageal echocardiography(TEE)was performed 10 minutes after induction of general anesthesia(T2)and before the end of surgery(T6)to ex-amine the coronary sinus(CS)flow spectrum and diameter,pulmonary venous flow spectrum,and calculate CS net antegrade flow velocity time integral(VTI).Femoral mean arterial pressure(MAP),central venous pressure(CVP),stroke volume(SV),cardiac index(CI)and peripheral vascular resistance index(SVRI)were recorded at T2,2 minutes before CPB(T3),the end of CPB(T5),and T6.The concentra-tions of blood glucose and lactate 5 minutes before anesthesia induction(T1),T3,30 minutes after CPB(T4),T5,T6,6 hours after surgery(T7),12 hours after surgery(T8),and 24 hours after surgery(T9)were recorded.The levels of high-sensitivity C-reactive protein(hs-CRP),high-sensitivity troponin I(hs-TnI),and creatine kinase isoenzyme(CK-MB)were recorded 1 day preoperatively,1 and 2 days post-operatively.Results Compared with group C,in group I,CS net antegrade flow VTI and blood flow per minute were significantly increased(P<0.05),and pulmonary venous peak atrial reversal wave velocity(ARp)was significantly reduced at T6(P<0.05),SV and CI were significantly increased and SVRI was significantly decreased at T5 and T6(P<0.05),lactate concentration was significantly decreased at T7 and T8(P<0.05),hs-CRP and CKMB were significantly decreased 1 and 2 days postoperatively(P<0.05),hs-TnI was significantly reduced 2 days postoperatively(P<0.05).Conclusion Continuous insulin admin-istration during cardiac surgery with CPB while maintaining blood glucose at 6.1-11.1 mmol/L can enhance myocardial blood perfusion,mitigate postoperative inflammatory response,and reduce myocardial injury.

Objective:To quantify the impact of injury-related deaths on the gender gap in life expectancy (GGLE).Methods:Abbreviated life table was used to analyse Tianjin residents' cause of death surveillance data from 2003 to 2021, and life expectancy was calculated by gender. SPSS 24.0 software was applied to calculate the injury-standardised mortality rate of Tianjin residents. The Arriaga decomposition method was used to calculate the effects of injury-related deaths on age-specific and urban-rural GGLE in 2003 and 2021.Results:The GGLE in Tianjin from 2003 to 2021 ranged from 2.63 to 4.47 years. Injury mortality rates declined significantly in males and showed no significant change in females. the incremental increase in life expectancy over the 19 years was 0.47 years (13.68%) for males, significantly higher than that for females (0.06 years, 1.09%). The GGLE caused by injury deaths in 2021 (0.34 years, 7.64%) decreased compared with 2003 (0.54 years, 20.40%) and decreased more in rural areas. Compared to 2003, the most significant reduction in the contribution rate of injury deaths on the GGLE was observed in the 5-49 age group in 2021, with a cumulative reduction of 12.11%. The contribution rates of transport accidents excluding motor vehicles, motor vehicle traffic accidents, drowning, accidental poisoning, and electrocution all decreased, with only motor vehicle traffic accidents increasing in rank, taking the first place in the injury contribution rates for 2021. The contribution rate of suicide was significantly higher in the 25-29 age group. The contribution of accidental falls was higher in the 50-79 age group and lower in the ≥85 age group, and that of other accidents and adverse effects was significantly lower in the ≥85 age group.Conclusions:Injury interventions for females in Tianjin should receive more attention, especially in preventing unintentional falls and other accidents and adverse effects among elderly females aged ≥85. Injury prevention for males should not be neglected, and efforts should be made to reduce the mortality rate of motor vehicle traffic accidents among males in rural areas of Tianjin. Attention should be paid to suicide intervention for males, especially those aged 25-29, and to prevent accidental falls among middle-aged and elderly males aged 50-79.
