Objective To investigate the predictive value of preoperative combined detection of neutrophil-to-lymphocyte ratio (NLR) and prothrombin time-international normalized ratio to albumin ratio (PTAR) for early abdominal infection after liver transplantation. Methods Clinical data of 287 recipients who underwent liver transplantation at the Liver Transplant Center of Beijing Friendship Hospital, Affiliated to Capital Medical University, from January 2020 to April 2024 were retrospectively analyzed. The patients were divided into infection group (n=60) and non-infection group (n=227) based on whether abdominal infection occurred within 30 days after surgery. The distribution characteristics of pathogens and infection time in infected patients were analyzed. Spearman correlation analysis was used to assess the correlation between NLR, PTAR, Child-Pugh score and preoperative model for end-stage liver disease (MELD) score. Univariate and multivariate logistic regression analyses were performed to identify risk factors for abdominal infection. Receiver operating characteristic (ROC) curves were plotted for NLR, PTAR, and the combined prediction model to evaluate their predictive efficacy for abdominal infection after liver transplantation. Based on the cutoff value of the combined model, recipients were divided into low-risk and high-risk groups, and Kaplan-Meier analysis was used to compare the cumulative incidence of abdominal infection within 30 days after surgery between the two groups. Results Among the 287 recipients who underwent liver transplantation, 60 developed bacterial or fungal abdominal infections postoperatively. A total of 86 strains were isolated from infected patients, with Gram-negative bacteria accounting for 58%, Gram-positive bacteria for 36%, and fungi for 5%. Preoperative NLR and PTAR were positively correlated with Child-Pugh and MELD scores (all 1 > r > 0, P < 0.05). Logistic regression analysis showed that preoperative NLR, preoperative PTAR, postoperative ICU stay duration and postoperative biliary leakage were risk factors for abdominal infection within 30 days after surgery. The area under the curve (AUC) for NLR, PTAR, Child-Pugh score and MELD score were 0.771, 0.735, 0.650 and 0.741, respectively. The AUC for the combined NLR and PTAR prediction model was 0.824 (95% confidence interval: 0.763-0.885, P < 0.001), with a cutoff value of 0.168. Kaplan-Meier analysis showed that the cumulative incidence of abdominal infection within 30 days after surgery was lower in the low-risk group than in the high-risk group, with statistically significant difference (P < 0.001). Conclusions Preoperative NLR and PTAR are independent risk factors for abdominal infection within 30 days after liver transplantation. The combined prediction model of NLR and PTAR may effectively identify high-risk recipients for early abdominal infection after liver transplantation, providing basis for early intervention.

Osteoporosis （OP） is a skeletal metabolic disease characterized by bone loss and destruction of bone microstructure. Changes in estrogen levels are not the only pathogenic factors for the occurrence and development of OP. MicroRNA （miRNA） plays an important regulatory role in cells. The complementary sequences of miRNA and targeted mRNA combine to inhibit the expression of targeted mRNA through post-transcriptional regulation， forming a complex regulatory network. Research suggests that miRNA is closely related to the occurrence and development of various diseases， including inflammatory diseases， metabolic diseases， and cancer. Targeted mRNA participates in post-transcriptional gene expression regulation in OP， mainly regulating the balance among bone construction， bone resorption， and osteoblast differentiation. Therefore， miRNA-based gene therapy is a rapidly developing disease treatment strategy. Traditional Chinese medicine can improve bone metabolism by intervening in miRNA differential expression to target and regulate osteogenic/osteoclast differentiation. This article summarized the targeting effects of miRNAs in physiological and developmental processes such as bone cell proliferation， differentiation， survival， and apoptosis， reviewed and classified their mechanisms of action and targets， and sorted out the current treatment methods of traditional Chinese medicine for preventing and treating OP and drugs that exert bone protective functions through miRNAs. This review is expected to provide theoretical reference and research guidance for future research on OP treatment by regulating miRNA.

The incidence and mortality rate of heart failure (HF) are increasing annually, resulting in a huge medical and economic burden worldwide. B-type natriuretic peptide (BNP) is the gold standard biomarker of HF recommended by national and international guidelines for the diagnosis and prognosis evaluation of HF. Recent studies suggest that BNP can be truncated in multiple forms by different enzymes rather than complete fragments in circulation, which can be contributing to the diagnosis and classification of HF. The immunoassay mostly used in clinics are unable to distinguish different truncated BNP forms due to cross-reactivity of antibody, while mass spectrometry is more accurate because it can easily distinguish through their mass-to-charge ratios. With the maturation of ambient ionization mass spectrometry and ion mobility mass spectrometry, it can help to simplify sample pre-treatment and improve the separation efficiency, in order to explore the clinical value of the heterogeneity of BNP truncated forms.

Trigeminal neuralgia is a manifestation of orofacial neuropathic pain disorder,always deemed to be an insurmountable peak in the field of pain research and treatment.The pain is recurrent,abrupt in onset and termination similar to an electric shock or described as shooting.A poor quality of life has been attributed to trigeminal neuralgia,as the paroxysms of pain may be triggered by innocuous stimuli on the face or inside the oral cavity,such as talking,washing face,chewing and brushing teeth in daily life.The pathogenesis of trigeminal neuralgia has not been fully elucidated,although the microvascular compression in the trigeminal root entry zone is generally considered to be involved in the emergence and progression of the pain disorder.In addition,orofacial neuropathic pain restricted to one or more divisions of the trigeminal nerve might be secondary to peripheral nerve injury.Based on current hypotheses regarding the potential causes,a variety of animal models have been designed to simulate the pathogenesis of trigeminal neuralgia,including models of compression applied to the trigeminal nerve root or trigeminal ganglion,chronic peripheral nerve injury,peripheral inflammatory pain and center-induced pain.However,it has not yet been possible to determine which model can be perfectly employed to explain the mechanisms.The selection of appropriate animal models is of great significance for the study of trigeminal neuralgia.Therefore,it is necessary to discuss the characteristics of the animal models in terms of animal strains,materials,operation methods and behavior observation,in order to gain insight into the research progress in animal models of trigeminal neuralgia.In the future,animal models that closely resemble the features of human trigeminal neuralgia pathogenesis need to be developed,with the aim of making valuable contributions to the relevant basic and translational medical research.

BACKGROUND:Seed cells are seeded on three-dimensional scaffold materials,and three-dimensional culture in bioreactors is a common in vitro tissue engineering culture method,but the changes in cell proliferation and metabolic patterns in bioengineered blood vessel construction are still unclear. OBJECTIVE:To explore the metabolic changes of cells such as oxygen consumption and their causes during the whole process of biological vascular tissue construction by in vitro bioreactor. METHODS:The self-built vascular bioreactor system was used as the platform;bovine vascular smooth muscle cells were used as the seed cells,and a conventional CO2 incubator provided the external gas environment for the cultivation process.Seed cells were seeded on a tubular porous polyglycolic acid scaffold material for three-dimensional culture,and the whole process included a one-week resting period and a seven-week pulsating tensile stress stimulation loading period.A non-invasive monitoring system was built,and the optical dissolved oxygen patch method was used to monitor the changes of dissolved oxygen in the culture solution in the reactor,and the glucose consumption and lactic acid production were measured by regular sampling.CCK-8 assay was used to determine the proliferation of smooth muscle cells on polyglycolic acid three-dimensional scaffold materials.Nicotinamide adenine dinucleotide oxidation state and reduction state ratio(NAD+/NADH)was utilized to understand cell proliferation and metabolism in the early stage of culture.RT-qPCR and western blot assay were applied to detect the expression of proliferation-related genes(Ki67)and glycolysis-related genes(GLUT-1,LDHA). RESULTS AND CONCLUSION:(1)The dissolved oxygen level in the culture solution was(4.314±0.380)mg/L from the cell injection to the end of the resting period(the first week),and gradually stabilized at(1.960±0.866)mg/L after the tensile stress stimulation(the last seven weeks);the two had significant changes(P<0.05).(2)The ratio of glucose consumption to lactic acid production in the cell culture medium YL/G increased rapidly after the cells were injected,and the highest value was above 1 on the fifth day,and then slow down to 0.5(The mean value of YL/G in the resting period was 0.89 and the mean value in the pressurized period was 0.57,P<0.05).(3)CCK-8 assay results showed that A450 value gradually increased after the cells were injected,and reached the highest value on the fifth day,reaching 3.17,and then slowly decreased.At the same time,it was found that Ki67 mRNA was up-regulated on the third day of culture,and then declined.The expression level of Ki67 protein was higher from the third day to the fifth day.(4)The detection of NAD+/NADH showed that the increase was obvious from the fifth to the seventh day after the injection of cells,and the expression of glycolysis-related genes(GLUT-1 and LDHA)was up-regulated and changed synchronously,and the relative expression was higher in the first five days.(5)The results showed that the tissue-engineered blood vessels were constructed using the vascular bioreactor and the smooth muscle cells in the early stage mainly proliferated and exhibited a metabolic feature of low oxygen consumption.The metabolic characteristics of high oxygen consumption were observed during the pulsatile tensile stress stimulation stage.

BACKGROUND:Osteoarthritis is a common chronic inflammation of joints caused by degenerative changes of articular cartilage.More and more studies have shown that mechanical stress is closely related to the development of osteoarthritis.The Hippo pathway is not only involved in the development of tissue cells,but also an effecting factor of mechanical stress,which is involved in the regulation of bone metabolism and cartilage metabolism. OBJECTIVE:Regulation of the Hippo pathway may become one of the new targets for intervention in osteoarthritis.Therefore,this paper reviewed the research on the effect of mechanical stress regulation of the Hippo pathway on osteoarthritis to provide ideas for the pathogenesis of osteoarthritis and provide a new theoretical basis for the treatment of osteoarthritis. METHODS:PubMed,Web of Science,Embase,CNKI,VIP,and WanFang databases were used for a literature search for articles published from inception to 2023 concerning the influence of mechanical stress on osteoarthritis and mechanical stress,Hippo pathway,and osteoarthritis.A total of 75 articles were finally reviewed. RESULTS AND CONCLUSION:(1)Different mechanical stresses may play different roles in cell proliferation,apoptosis and differentiation,osteoarthritis inflammation,and vascular homeostasis in osteoarthritis.(2)Hard extracellular matrix,low cell density,medium shear force,medium tensile force,and compression force can achieve cell proliferation,osteogenic differentiation,and vascular homeostasis,and inhibit inflammatory response by activating YAP/TAZ.(3)Soft extracellular matrix,high cell density,excessive shear force,excessive tensile force,and compressive force inhibit cell proliferation,enhance cartilage differentiation,disrupt vascular homeostasis,and promote inflammation through inactivation of YAP/TAZ,thus promoting the process of osteoarthritis.

ObjectiveTo investigate the prevalence of stroke in Songjiang District from 2017 to 2022, to analyze the epidemiological characteristics of stroke incidence, so as to provide a scientific basis for the formulation of stroke prevention and control policies. MethodsData of new stroke incidence from 2017 to 2022 in Songjiang District were obtained from the Shanghai Stroke and Acute Myocardial Infarction Registration and Reporting Information System. In addition, different classifications such as time of onset, gender, age group and types of stroke, were statistically analyzed. Statistical indicators, such as the number of incidence, crude incidence rate, standardized incidence rate and average age of incidence were calculated simultaneously. Joinpoint software were used to calculate the annual change percentage (APC) and the trend of stroke incidence in Songjiang District. ResultsFrom 2017 to 2022, the newly reported cases of stroke were 12 988 in Songjiang District, the crude incidence rate was 325.76/10⁵, and the standardized incidence rate was 127.58/10⁵. The crude incidence rate and standardized incidence rate in males were 363.45/10⁵ and 157.17/10⁵, respectively, but 288.68/10⁵ and 99.02/10⁵ in females. The mean age of onset was (73.12±11.75) years, of which the mean age of onset was (70.86±11.96) years for men and (75.91±10.85) years for women. The incidence of stroke increased with age, rising rapidly after 60 years and reaching a peak in the age group of ≥ 80 years old. The crude incidence rate and standardized incidence rate of stroke in Songjiang District showed a downward trend from 2017 to 2022, with an APC of -6.20% and -8.01%, respectively (P=0.018, 0.007). The newly reported stroke was dominated by ischemic stroke, accounting for 82.81% of the total cases, with a crude incidence rate of 269.77/10⁵ and a standardized rate of 103.84/10⁵. The incidence of stroke presented seasonal characteristics, with the highest incidence in winter, accounting for 26.11% of the whole year. ConclusionThe incidence rate of stroke in Songjiang District shows a declined trend, but the overall incidence is still at a high level. The situation of prevention and control is still serious, with a heavy disease burden. It is necessary to strengthen health education and disease management for the elderly.

Objective:To analyze the relationship between health belief and the stages of parental decision-making on childhood 13-valent pneumococcal conjugate vaccine (PCV13) immunization in China.Methods:Cross-sectional multistage survey sampling method was used to select study subjects. The study subjects were parents who were aged 20-45 years and had one and more children ≤5 years old in three cities in China. A self-administered questionnaire designed based on health belief model was used to collect the information. Multinomial logistic regression analysis was used to assess the relationships between perceived susceptibility, perceived severity of illness, perceived effect of PCV13 and stages of parental decision-making on childhood PCV13 immunization.Results:A total of 1 716 valid questionnaires were returned (89.33%). The average age of the study subjects was (35.33±4.95) years, and 79.60% of them were women. In the study subjects, 48.31% had in action, 21.79% were in contemplation and 29.90% were in pre-contemplation. The multinominal logistic regression analysis indicated that high perceived susceptibility ( OR=0.14, 95% CI:0.09-0.22; OR=0.54, 95% CI:0.39-0.76), high perceived severity of illness ( OR=0.55, 95% CI:0.42-0.73), and high perceived effect of PCV13 ( OR=0.27, 95% CI:0.18-0.40; OR=0.51, 95% CI:0.32-0.81) were significantly lower in those who were in contemplation or pre-compared with those who had in action. For study subjects with low perceived susceptibility, high perceived effect of PCV13 might decrease the probabilities of contemplation ( OR=0.53, 95% CI:0.32-0.87) and pre-contemplation ( OR=0.27, 95% CI:0.18-0.41). For those with high perceived susceptibility, perceived severity of illness might decrease the probability of contemplation ( OR=0.43, 95% CI:0.23-0.82). Conclusions:Childhood PCV13 vaccination willingness and level is low in China. It is important to pay greater attention to the intervention on health belief in child parents, such as perceived effect of PCV13, perceived severity of illness, and perceived susceptibility, in health policy development and health promotion.
