Objective:To analyze the individual and cumulative effects of unhealthy lifestyle on the prevalence of hypertension, diabetes and dyslipidemia in old adults in China, and find out the critical lifestyle in the network.Methods:Based on the baseline data of Yunnan Behavior and Disease Surveillance Cohort in 2021, a total of 16 763 older adults aged ≥60 years were included in our study. The unhealthy lifestyle factors including smoking, drinking, unhealthy eating habit, lower physical activity level, abnormal BMI and abnormal waist circumference. We calculated the unhealthy lifestyle score by using the cumulative exposures of each participant. Multiple logistic regression and mixed graphical models were used to describe the association between unhealthy lifestyle and the prevalence of hypertension, diabetes and dyslipidemia.Results:The prevalence of hypertension, diabetes and dyslipidemia were 57.0%, 11.5% and 37.0%, respectively. Most of the unhealthy lifestyles included in the study were risk factors for hypertension, diabetes and dyslipidemia, and the risks of disease increased with the increase of the unhealthy lifestyle score. The participants with the highest score (score: 6) had significantly higher prevalence of hypertension ( OR=3.99, 95% CI: 1.81-8.80), diabetes ( OR=4.64, 95% CI: 1.64-13.15) and dyslipidemia ( OR=4.26, 95% CI: 2.08-8.73) compared with those with lowest score (score: 0). In the network constructed by mixed graphical model, abnormal waist circumference (bridge strength=0.81) and hypertension (bridge strength=0.55) were vital bridge nodes connecting unhealthy lifestyle and hypertension, diabetes and dyslipidemia. Conclusions:The unhealthy lifestyle score was associated with risks for hypertension, diabetes and dyslipidemia. Abnormal waist circumference was the key factor for chronic diseases in old adults.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: To investigate the attitudes and demands of parents of children in Luzhou towards family based child sexual abuse prevention education. Methods: A self administered anonymous questionnaire survey was conducted among parents of children in Luzhou City who were selected from stratified cluster sampling. Multiple linear regression model was used to analyze parents attitudes. Results: Parents attitude towards prevention of sexual assault education was positive (average score 16.70± 3.67 ). The results of multiple regression analysis showed that parents of only child ( β =0.30), parents who participated in related activities ( β =1.28), communicated with relatives and friends ( β =0.81), and lived in urban areas ( β =0.49) had more positive attitudes. In terms of parental factors, average annual family income higher than 100 000 yuan ( β =0.39), mothers of young children ( β =0.88), and parents with a high level of knowledge about sexual assault prevention education ( β =0.98), the mother being a teacher or a medical staff ( β =0.52), and educational background of the mother being high school/secondary school ( β =1.03), college/undergraduate or above ( β =1.42) were associated with more positive attitudes( P <0.01). The results of demand analysis showed that parents had high demand for child s self protection (96.86%). Conclusion Parents of young children in Luzhou City show generally positive attitude and high demand towards family based sexual abuse prevention. Knowledge training and publicity regarding child sexual abuse should be improved for children who had siblings, from rural and township areas, and whose parents with low educational background.

Nucleotide-binding oligomerization domain containing protein 2 (NOD2) is a member of intracellular pattern recognition receptor. After being activated, it will induce the release of inflammatory factors through a series of signal cascade transduction, thus playing an important role in the innate immune response. The abnormal NOD2 signaling pathway is involved in the occurrence and development of many diseases, especially the single nucleotide polymorphisms (SNPs) of the NOD2 gene have been identified to be closely associated with autoinflammatory diseases (AIDs). Therefore, inhibitors targeting NOD2 pathway have great potential in the treatment of inflammatory immune diseases. This review presents the recent progress of NOD2 receptor-mediated signal transduction pathways and its regulation mechanisms, the relationship between NOD2 and AIDs, and the inhibitors of NOD2 pathway.

Violet root rot is one of the main root diseases in the production process of Pseudostellaria heterophylla. To clarify the pathogenic species that cause the violet root rot of P. heterophylla in Fujian province, the roots and the sclerotia with violet root rot symptoms were collected from the main producing areas of P. heterophylla(Fujian province) from 2017 to 2021, and the pathogens were isolated by tissue separation method and identified by morphology and multi-gene phylogenetic analysis. Additionally, the biological characteristics of the pathogens were studied and the fungicides were determined. The results showed that 78 strains of violet root rot were isolated from the collected root samples, which belonged to one type after preliminary morphological identification. Two represen-tative strains were selected from the pathogens for multi-gene phylogenetic analysis, and they were clustered with Helicobasidium mompa together. The suitable culture conditions for the mycelium were OA medium, 25 ℃, pH 6, and ammonium oxalate as the nitrogen source. The lethal temperature of the mycelium was 50 ℃ for 10 minutes. Moreover, 99.1% propiconazole and 98.7% azoxystrobin had the optimal bacteriostatic effect, and the concentrations with the 50% bacteriostatic rate were 16.85 and 12.24 μg·mL~(-1), respectively. On the basis of the above results, the pathogen causing violet root rot of P. heterophylla in Fujian province was H. mompa. The medium type, growth temperature, pH value, nitrogen source, etc. had significant effect on the growth of mycelium.

To study the residue and dietary risk of propiconazole in Panax notoginseng and the effects on physiological and bioche-mical properties of P. notoginseng, we conducted foliar spraying of propiconazole on P. notoginseng in pot experiments. The physiolo-gical and biochemical properties studied included leaf damage, osmoregulatory substance content, antioxidant enzyme system, non-enzymatic system, and saponin content in the main root. The results showed that at the same application concentration, the residual amount of propiconazole in each part of P. notoginseng increased with the increase in the times of application and decreased with the extension of harvest interval. After one-time application of propiconazole according to the recommended dose(132 g·hm~(-2)) for P. ginseng, the half-life was 11.37-13.67 days. After 1-2 times of application in P. notoginseng, propiconazole had a low risk of dietary intake and safety threat to the population. The propiconazole treatment at the recommended concentration and above significantly increased the malondialdehyde(MDA) content, relative conductivity, and osmoregulatory substances and caused the accumulation of reactive oxygen species in P. notoginseng leaves. The propiconazole treatment at half(66 g·hm~(-2)) of the recommended dose for P. ginseng significantly increased the activities of superoxide dismutase(SOD), peroxidase(POD), and catalase(CAT) in P. notoginseng leaves. The propiconazole treatment at 132 g·hm~(-2) above inhibited the activities of glutathione reductase(GR) and glutathione S-transferase(GST), thereby reducing glutathione(GSH) content. Proconazole treatment changed the proportion of 5 main saponins in the main root of P. notoginseng. The treatment with 66 g·hm~(-2) propiconazole promoted the accumulation of saponins, while that with 132 g·hm~(-2) and above propiconazole significantly inhibited the accumulation of saponins. In summary, using propiconazole at 132 g·hm~(-2) to prevent and treat P. notoginseng diseases will cause stress on P. notoginseng, while propiconazole treatment at 66 g·hm~(-2) will not cause stress on P. notoginseng but promote the accumulation of saponins. The effect of propiconazole on P. notoginseng diseases remains to be studied.

Lung cancer is the leading cause of cancer death, and non-small cell lung cancer (NSCLC) accounts for 85%. Immunotherapy has significantly improved the clinical prognosis of patients with NSCLC. However, because of the complexity and heterogeneousness of the tumor microenvironment, only a subset of individuals can benefit from immunotherapy. Therefore, it is necessary to explore effective predictive biomarkers for immunotherapy of NSCLC. Tertiary lymphoid structure (TLS) is an ectopic lymphoid organ that is highly similar to secondary lymphoid organs (SLO), and the presence of TLS has been found to be closely associated with a good prognosis in immunotherapy for a variety of solid tumors, including NSCLC. This article provides a review of the prognostic role of tertiary lymphoid structures in immunotherapy of NSCLC, in order to offer references for screening suitable candidates for immunotherapy of NSCLC and develop personalized and precise treatment plans.

Aim To establish stable and reliable animal models of Blau syndrome (BS) in vivo. Methods C57BL/6J mice were intraperitoneally injected with muramyl dipeptide (MDP) or L18-MDP to induce systemic inflammatory model of BS. Meanwhile, positive drug etanercept (ETN) was set to investigate the response of the model to evaluate effectiveness. SD rats were intravitrealiy injected with MDP to establish BS-associated uveitis model. Serum levels of TNF-a, IL-6 and IL-8 were detected by enzyme linked immunosorbent assay (ELISA). Histopathologic al changes of rat eyeballs were detected by HE staining and the expressions of p65, p-ERK, p-p38, p-JNK, TNF-a, IL-6 and IL-8 in vitreous were determined by immunohistochem-istry (IHC) staining. Results The serum level of TNF-a in mice increased after intraperitoneal injection of MDP (P < 0.05), and increased significantly after L18-MDP injection (P < 0.01). Meanwhile, the levels of IL-6 and IL-8 were also markedly induced by L18-MDP (P < 0. 01, P < 0. 01). ETN treatment evidently inhibited the increased levels of these above cytokines induced by L18-MDP (P < 0. 05, P < 0. 01). After the intravitreous injection of MDP in SD rats, there were numerous inflammatory cells infiltrated in retina and vitreous, and the retina was seriously damaged. The staining levels of p65, p-ERK, p-p38, p-JNK, TNF-a, IL-6 and IL-8 in eyeball tissues were significantly enhanced. Conclusions The systemic animal model of BS can be successfully established by intraperitoneal injection of L18-MDP in C57BL/6J mice, and the good BS-relat-ed uveitis can be induced by intravitreous injection of MDP in SD rats, which provides the simple, convenient, repeatable and i-deal animal models for exploring the pathogenesis of BS and e-valuating the efficacy of drugs.

Aim To explore the effect of Buyang Huanwu Decoction on cerebral ischemia-reperfusion injury in rats by regulating autophagy through PI3K/AKT pathway. Methods The rats were randomly divided into five groups(n=10): sham operation group(Sham), model group(Model), Buyang Huanwu Decoction group(BYHWD), PI3K inhibitor group(LY294002)and Vehicle group(Vehicle). Except Sham group, the other groups were treated with 2h ischemia and 72 h reperfusion for modeling. The Zea Longa score was used to assess the neurological defects, HE was used to observe brain injury in the ischemic penumbra(IP), immunofluorescence was employed to detect LC3, and Western blot was used to detect pathway and autophagy marker proteins. Results Compared BYHWD group with model group, the neurological score of rats decreased, cerebral infarction volume decreased, the pathological lesions of brain IP were relieved, PI3K and p-AKT/AKT expression increased, and LC3Ⅱ/ decreased and p62 increased(P<0.05). The regulatory effect of BYHWD was weakened by LY294002(P<0.05). Conclusion Buyang Huanwu Decoction alleviates cerebral ischemia-reperfusion injury in rats by activating PI3K/AKT pathway to inhibit autophagy.
