Objective To probe the spatial distribution of respiratory-related nuclei throughout the whole brain,and to investigate the circuit and projection links between the paraventricular hypothalamic nucleus (PVN)and the preB?tzinger complex (preB?tC)in mice.Methods Using a retrograde tracing strategy from peripheral to central,pseudorabies viruses (PRV)were microinjected into the diaphragm of mice to retrogradely label the upstream inputs brain regions from spinal respiratory phrenic motor neurons. The anterograde non-transsynaptic tracing viruses (AAV2/9-EGFP)were microinjected into the PVN to label the downstream brain region of the PVN;And using the Cre/loxP gene expression strategy,Dio-EGFP and Retro-Cre viruses were injected in the PVN and preB?tC,respectively,to validate the PVN-preB?tC circuit and the projection relationship between the two.Results The results of PRV-mediated retrograde tracing showed that PRV-EGFP-positive neurons were distributed in several brain regions such as PVN,preB?tC,nucleus tractus solitarii (NTS),locus coeruleus (LC)and periaqueductal grey (PAG).Except for the medulla oblongata region,the PVN brain region had the highest percentage of PRV-EGFP-positive neurons (P<0.0001 ).After AAV2/9-EGFP viruses were injected in the PVN,green neurofibrils were observed in the preB?tC brain region after viral infection;Dio-EGFP and Retro-Cre viruses were injected in the PVN and preB?tC,respectively,and green neuronal cells were seen in the brain region of the PVN after viral infection.Conclusion PVN is an important upstream input nucleus of spinal respiratory phrenic motor neurons,and has the potential to regulate respiration through direct projections from PVN-preB?tC circuit.

Objective:To investigate the prevalence of sarcopenia as defined by the third lumbar skeletal muscle index (L3-SMI) and explore its impact on drug therapy in patients with inflammatory bowel disease (IBD).Methods:The baseline abdominal CT images of 230 patients with IBD hospitalized in the First Hospital of Shanxi Medical University from December 2018 to December 2022 were retrospectively analyzed to obtain L3-SMI. The optimal cut-off value of L3-SMI to define sarcopenia was determined using receiver operating characteristic curve analysis. The IBD group included 164 cases of ulcerative colitis (UC) and 66 cases of Crohn's disease (CD), compared with 100 cases of the normal control. The clinical data and biochemical indicators, such as body mass index (BMI), albumin (ALB), pre-albumin (PA), disease activity and therapeutic drugs, were collected. Outcomes were followed up, including the optimization of baseline drug therapy, the initiation of additional biological agents or combined drug therapy. Multivariate logistic regression analysis was used to identify risk factors for the escalation of drug therapy, and the nomogram was constructed and evaluated for the prediction of drug regimen escalation in patients with IBD.Results:The prevalence of sarcopenia in the IBD population in this study was 39.6%, among whom 36.0% were with ulcerative colitis and 48.5% with Crohn's disease. The prevalence of malnutrition (BMI<18.5) in IBD patients was 18.7%, whereas 69.2% of patients with concurrent IBD and sarcopenia had a BMI≥18.5 . The median L3-SMI of IBD patients was significantly lower than that of normal controls (36.30 cm 2/m 2vs. 39.37 cm 2/m 2, P=0.004). Sarcopenia ( OR=3.33, 95% CI: 1.06 to 10.50, P=0.040) was associated with the escalation of drug therapy in patients with IBD. Based on the patient's age, presence or absence of sarcopenia, albumin and BMI, the nomogram prediction model was established, with the area under the curve (AUC) of 0.762 (95% CI: 0.691 to 0.834), showing good discriminating performance. The calibration curve and Hosmer-Lemeshow goodness-of-fit test demonstrated good consistency between the predicted and observed data ( χ2 =11.906, P=0.156). Decision curve analysis showed potential benefits of the prediction model in clinical settings. Conclusion:Sarcopenia is common in patients with IBD, which is related to the escalation of drug therapy in patients with IBD.

Objective To analyze the recurrence factors of the patients with intermediate risk papillary thyroid carcinoma(PTC)after radioactive iodine treatment(RAIT).Methods A total of 254 intermediate risk PTC patients after RAIT from January 2018 to May 2020 in our hospital were enrolled into this study.Chi square test and multivariate analysis were applied to analyze the main recurrence factors after RAIT.Results Thirty four(13.4%)patients with intermediate risk PTC relapsed after RAIT.The primary tumor size,lymph node metastasis staging,and pre-ablation stimulated thyroglobulin(psTg)were associated with tumor recurrence.According to the receiver operating characteristic(ROC)curve,psTg 25.6 μg/L was the best cutoff value for predicting recurrence.Further multivariate analysis revealed that lymph node metastasis staging and psTg levels were independent factors of predicting PTC recurrence.When the patients with N1b and psTg≥25.6 μg/L,the incidence of tumor recurrence after RAIT was 58.3%.While the patients with N1a and psTg<25.6 μg/L,the incidengce of tumor recurrence was only 2.3%.Conclusions Lymph node metastasis staging and psTg level are the important indicators of PTC recurrence,and combining these two indicators can help predict tumor recurrence after RAIT.

Objective:To observe the effect of large pushing Tianheshui manipulation intervention on the body temperature of young rabbits with endotoxin-induced fever and discuss its antipyretic mechanism.Methods:Thirty-two young rabbits meeting the standards were selected from 40 ordinary young male New Zealand rabbits after being adapted for 7 d,and randomly divided into a normal group,a model group,a large pushing Tianheshui group,and an ibuprofen group according to the random number table method,with 8 rabbits in each group.Rabbits in the model group,the large pushing Tianheshui group,and the ibuprofen group were subjected to preparing the endotoxin-induced fever model by intravenous lipopolysaccharide from the marginal ear vein.Rabbits in the large pushing Tianheshui group received Tuina(Chinese therapeutic massage)manipulation intervention 1.5 h and 2.5 h after modeling,respectively.Rabbits in the ibuprofen group were intragastrically given ibuprofen suspension 1.5 h after modeling.The dynamic changes in body temperature were observed for the young rabbits after fever modeling.Enzyme-linked immunosorbent assay was used to determine the content changes in positive mediators of hypothalamic body temperature,including prostaglandin(PG)E2 and cyclic adenosine monophosphate(cAMP),as well as negative mediators of hypothalamic body temperature,including arginine vasopressin(AVP)and α-melanocyte stimulating hormone(α-MSH).Results:The body temperature of the young rabbits in the model group was significantly higher than that in the normal group at 0.5-4.0 h,5.0 h,and 5.5 h after modeling(P＜0.01),showing two obvious fever peaks in the model group at 1.5 h and 3.0 h after modeling,respectively,with the highest peak at 1.5 h.Compared with the model group,body temperatures of the large pushing Tianheshui group and the ibuprofen group decreased significantly after 0.5 h of intervention(P＜0.05).Compared with the normal group,the contents of PGE2 and cAMP were significantly increased(P＜0.05),and the contents of AVP and α-MSH were significantly decreased(P＜0.01)in the hypothalamus of the model group.Compared with the model group,the contents of PGE2 and cAMP were significantly decreased(P＜0.01),and the levels of AVP and α-MSH were significantly increased(P＜0.01)in the hypothalamus in the large pushing Tianheshui group and the ibuprofen group.There were no significant differences in the PGE2,cAMP,AVP,and α-MSH contents in the hypothalamus between the ibuprofen group and the large pushing Tianheshui group(P＞0.05).Conclusion:Large pushing Tianheshui manipulation has a significant antipyretic effect on endotoxin-induced fever in young rabbits.The mechanism may be related to inhibiting the positive regulators(PGE2 and cAMP)and promoting the negative regulators(AVP and α-MSH)of hypothalamic control of body temperature.
