OBJECTIVE To investigate the potential mechanism by which Juanxiao decoction improves bronchial asthma （hereinafter referred to as “asthma”） based on the nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3） inflammasome signaling pathway. METHODS Female SD rats were randomly assigned to normal group， model group and Juanxiao decoction low-， medium- and high-dose groups （0.36， 0.72 and 1.44 g/kg， calculated based on crude drug weight）， as well as positive control group （Dexamethasone acetate tablets， 0.2 mg/kg）， with 10 rats in each group. Except for the normal group， asthma models were established in the remaining groups via intraperitoneal injection of ovalbumin combined with aluminum hydroxide， followed by nebulized inhalation of ovalbumin. On day 14 of the experiment， rats in each group received intragastric administration of the corresponding solution or normal saline， once a day， for 7 consecutive days. Following the final administration， the following parameters were measured in each group： lung function indexes （forced vital capacity， forced expiratory volume in 0.3 second， peak expiratory flow）， serum levels of inflammatory markers （interleukin-1β， interleukin- 18）， and the percentages of inflammatory cells （lymphocytes， eosinophils， neutrophils） in bronchoalveolar lavage fluid. Histopathological changes in lung tissue were observed， and the protein and mRNA expressions of nuclear factor-kappa B （NF- κB）， NLRP3 and caspase-1 in lung tissue were detected. RESULTS Compared with the normal group， pathological changes such as alveolar wall thickening and inflammatory cell infiltration were observed in rats in the model group. All pulmonary function indicators were significantly reduced in rats in the model group and the administration groups. The levels of inflammatory markers， the percentages of inflammatory cells， and the protein and mRNA expressions of NF-κB， NLRP3 and caspase-1 were significantly elevated or up-regulated （P＜0.05）. Compared with the model group， pathological changes in rats in each dosage group of Juanxiao decoction were significantly alleviated， and all quantitative indicators showed dose-dependent improvements （P＜0.05）. CONCLUSIONS Juanxiao decoction can reduce airway inflammatory responses in asthmatic rats， alleviate lung function impairment， and improve pathological changes such as inflammatory cell infiltration. Those effects may be related to the inhibition of the NLRP3 inflammasome signaling pathway.

BACKGROUND: The American Heart Association (AHA) introduced the concept of cardiovascular-kidney-metabolic (CKM) health and stage, reflecting the interaction among metabolism, chronic kidney disease (CKD), and the cardiovascular system. However, the association between CKM stage and the long-term risk of cardiovascular disease (CVD) has not been validated. This study aimed to evaluate the long-term CVD risk associated with CKM health metrics and CKM stage using data from a population-based cohort study. METHODS: In total, 5293 CVD-free participants were followed up to around 13 years in the Chinese Multi-provincial Cohort Study (CMCS). Considering the pathophysiologic progression of CKM health metrics abnormalities (comprising obesity, central adiposity, prediabetes, diabetes, hypertriglyceridemia, CKD, and metabolic syndrome), participants were divided into CKM stages 0, 1, and 2. The time-dependent Cox regression models were used to estimate the cardiovascular risk associated with CKM health metrics and stage. Additionally, broader CVD outcomes were examined, with a specific assessment of the impact of stage 3 in 2581 participants from the CMCS-Beijing subcohort. RESULTS: Among participants, 91.2% (4825/5293) had at least one abnormal CKM health metric, 8.8% (468/5293), 13.3% (704/5293), and 77.9% (4121/5293) were in CKM stages 0, 1, and 2, respectively; and 710 incident CVD cases occurred during a median follow-up time of 13.3 years (interquartile range: 12.1 to 13.6 years). Participants with each poor CKM health metric exhibited significantly higher CVD risk. Compared with stage 0, the hazard ratio (HR) (95% confidence interval [CI]) for CVD incidence was 1.31 (0.84-2.04) in stage 1 and 2.27 (1.57-3.28) in stage 2. Significant interactive impacts existed between CKM stage and age or sex, with higher CVD risk related to increased CKM stages in participants aged <60 years or females. CONCLUSION These findings highlight the contribution of CKM health metrics and CKM stage to the long-term risk of CVD, suggesting the importance of multi-component recognition and management of poor CKM health in CVD prevention.

Objective:To explore the difference of blood pressure compliance rate in patients with continuous ambulatory peritoneal dialysis (CAPD) in the internet of things (IoT) follow-up and conventional care.Methods:CAPD patients from 3 peritoneal dialysis centers from May 2019 to October 2019 were included in this retrospective cohort study. They were divided into IoT group and conventional care group according to the way of follow-up. The difference in blood pressure compliance rate during 1 year of follow-up between the two groups was observed. The primary outcome was defined as the proportion of patients with blood pressure compliance rate≥85%.Results:A total of 75 patients were included in this study, in during 32 patients in IoT group and 43 patients in conventional care group. The comparison of baseline data between the two groups showed that the dialysis age of patients in IoT group was shorter ( P<0.01). After a median of 9(9, 12) months follow-up, the median blood pressure compliance rate was 85.2% (65.2%, 95.1%), and 25 patients (65.6%) in IoT group had met the target of blood pressure compliance rate≥85%, which was significantly higher than that in the conventional care group (17 cases, 39.5%) ( χ2=4.996, P=0.025). The cumulative probability of the target of blood pressure compliance rate≥85% was 97%, 90%, 90% and 52%, respectively in IoT group, while 95%, 86%, 55% and 34%, respectively in conventional care group after 3, 6, 9 and 12 months of follow-up, and the different between the two groups was significant (Log-rank χ2=4.774, P=0.029). Adjusted for age, sex and dialysis age, the multivariate Cox proportional risk regression model showed that serum creatinine level(for every 1 μmol/L increase, HR=1.002, 95% CI 1.000-1.003, P=0.033), follow-up mode (IoT follow-up vs conventional care, HR=0.023, 95% CI 0.003-0.210, P=0.001), follow-up times (for each additional time, HR=0.879, 95% CI 0.823-0.939, P<0.001) and the rate of weight compliance (for each increase of 1%, HR=0.964, 95% CI 0.939-0.991, P=0.008) was the independent influencing factors for the blood pressure compliance rate<85%. The results of subgroup analysis showed that patients with shorter dialysis age (<10 months) and in the centers where the nurses finished the PD follow-up work as part-time job had better blood pressure control in IoT follow-up. Conclusions:IoT follow-up is helpful to improve CAPD patients' blood pressure compliance rate. Elevated serum creatinine level at baseline is the independent risk factor associated with poor blood pressure compliance. However, IoT follow-up, more follow-up times and the elevated rate of weight compliance are the protective factors for blood pressure compliance. IoT follow-up mode is more recommended for patients with short dialysis age and for dialysis centers where most of the nurses are part-time.

Objective To investigate the expression of neurotrophins receptor 75NTR in human breast cancer resistant cell line and its correlation with multidrug resistance. Methods Western blot was used to detect the expression level of p75NTR protein in various breast cancer cell lines and multidrug resistant cell lines. The over-expression vector and siRNA vector of p75NTR were constructed by gene recombination method. Western blot was used to detect the expression levels of p75NTR protein in transfected p75NTR and p75NTR - siRNA breast cancer resistant cell line MDA-MB-231/ADR;the sensitivity of MDA-MB-231 and MDA-MB-231/ADR to different chemotherapeutic anticancer drug (PTX ,ADM ,GEM ,DDP ,OXA) and the multi-drug resistance effects in over-expression and knock-down p75NTR MDA-MB-231/ADR were detected by CCK-8 assay. Results Western blot result showed that the expressions of p75NTR protein in the multidrug-resistant breast cancer cell lines MDA-MB-231/ADR and MCF-7/5-FU were higher than that of other breast cancer cell lines. Over-expression of p75NTRcan up-regulate the expression of p75NTR protein in MDA-MB-231/ADR;the CCK-8 assay indicated that over-expression of p75NTR can effectively enhance the resistance of MDA-MB-231/ADR cells to ADM,GEM and OXA. Conclusion The expression of p75NTR in breast cancer resistant cell line is higher than that of its parental cell line;over-expression of p75NTR can reduce the sensitivity to chemotherapeutic drugs and promote its multidrug resistance.

Objective To explore the effect of evidence-based nursing intervention in senile patients with long-term nasal feeding.Methods Totals of 180 senile patients with long-term nasal feeding who were hospitalized from January, 2013 to June, 2015 were selected as the research objects and were randomly divided into observation group and control group according to the order of admission. Patients in the observation group were given nursing intervention and patients in the control group were given routine care. Complications of nasal feeding, amount of nasal feeding in single time and interval time of nasal feeding were compared between the two groups.Results There was no significant difference in the complications of nasal feeding between the two groups (P>0.05). But compared with the control group, the workload of the nasal feeding in the observation group was significantly reduced and the resting time of the digestive system of patients was prolonged obviously. Conclusions Application of evidence-based nursing intervention in senile patients with long-term nasal feeding can effectively reduce the workload of clinical nurses and reduce hungry sensation of patients.

Objective To introduce improved program for traction wire production in endoscopic submucosal dis-section assisted by oral traction. Methods A retrospective analysis was performed on 40 patients who received en-doscopy intervention. Through the use of improved traction and normal traction, they were divided into experimental group and control group. Then analyze and compare their clinical data like gender, age, traction line installed perfect time, fixed lesions after hemostatic clip off times, one-time complete resection, enbloc resection rate, bleeding and perforation and other complications and other clinical conditions. Results The improvement time was (53.30 ±12.85) s in experimental group, it was significantly shorter than that in control group (105.00 ± 11.68) s ( = 3.42, <0.05). The experimental group fixed lesions after hemostatic clamp off times were significantly less than that in con-trol group (χ2=2.37, <0.05). Conclusions Using innovative methods, adequate preoperative preparation, the op-erator's tacit understanding of nursing cooperation, close attention to the disease after surgery is the key to achieve the desired results of endoscopic surgery.
