ObjectiveTo explore the effect and mechanism of Qigui Didang decoction， formulated based on the principle of Tonifying Deficiency and Unblocking Collaterals， on improving metabolic memory of db/db mice with diabetic nephropathy （DN） through silent information regulator 1 signal regulator 1 （Sirt1）/p53/nuclear factor kappa-B （NF-κB） p65 pathway. MethodsFifteen db/db mice were randomly divided into model group （10 mL·kg^-1·d^-1）， resveratrol group （20 mg·kg^-1·d^-1）， and Qigui Didang decoction group （3.34 g·kg^-1·d^-1） Another five db/m mice were selected as the normal group （10 mL·kg^-1·d^-1）. After the intervention， the kidney weight of each group was measured， and the kidney index （KI） was calculated. Fasting blood glucose （FBG）， creatinine （CRE）， β2-microglobulin （β2-MG）， blood urea nitrogen （BUN）， and cystatin C （CysC） were measured. Renal pathology was observed by hematoxylin-eosin （HE） staining and Masson staining. The mRNA and protein expression levels of Sirt1， NF-κB， tumor suppressor gene p53， interleukin-1β （IL-1β）， and cysteine aspartate protease-3 （Caspase-3） were detected using real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultsCompared with the normal group， the model group showed disordered renal structure， obvious renal damage， and markedly elevated levels of renal function indexes （CRE， β2-MG， BUN， and CysC） （P<0.01）. The KI and blood glucose were significantly increased （P<0.01）， while Sirt1 expression was markedly decreased （P<0.01）. Expression levels of NF-κB p65， p53， IL-1β， and Caspase-3 were increased significantly （P<0.05）. Compared with those in the model group， DN mice treated with Qigui Didang decoction exhibited significantly decreased FBG， improved renal function， and markedly decreased KI （P<0.01）， along with reduced CRE， β2-MG， BUN， and CysC levels （P<0.05）. Protein expression of Sirt1 was significantly upregulated （P<0.05）， while that of NF-κB p65， p53， IL-1β， and Caspase-3 was markedly decreased （P<0.05）. The mRNA expression levels of NF-κB p65， p53， IL-1β， and Caspase-3 were significantly decreased （P<0.05）. The staining results indicate improved renal fibrosis， significantly decreased fiber deposition （P<0.05）， and less inflammatory infiltration in the Qigui Didang decoction group. ConclusionThe findings suggest that Qigui Didang decoction can alleviate the metabolic memory effect of DN， thereby inhibiting renal cell apoptosis and inflammatory response in mice， and improving renal function. The mechanism of action is closely related to the Sirt1/p53/NF-κB p65 signaling pathway.

Objective: To analyze the serotypes and drug resistance of Salmonella isolated from food-borne disease surveillance samples in Longwan District, Wenzhou City, Zhejiang Province, so as to provide evidence for the prevention and treatment of Salmonella infection. Methods: Salmonella strains isolated from feces or anal swabs of patients with foodborne diarrhea in Longwan District People's Hospital from 2018 to 2024 were collected. After re-identification, slide agglutination test was used to identify serotypes. The drug susceptibility test of live Salmonella strains was performed using the broth microdilution method, and the resistance patterns were analyzed. Results: A total of 2 293 samples were collected, and 186 strains of Salmonella were isolated, with a detection rate of 8.11%. The detection rate was higher from May to October. A total of 28 Salmonella serotypes were identified, with S. typhimurium (72 isolates, 38.71%), S. enteritidis (31 isolates, 16.67%), and S. London (30 isolates, 16.13%) being dominant. Among the 121 Salmonella live strains, 20 strains were susceptible to 14 antibacterial drugs. A total of 101 strains were resistant to antibacterial drugs, and the drug resistance rate was 1.65%-67.77%, with the drug resistance rate of ampicillin being the highest, and the drug resistance rate of imipenem was the lowest. S. typhimurium had the highest resistance rate to tetracycline (78.26%). S. enteritidis had the highest resistance rate to ampicillin (100.00%). S. London had the highest resistance rate to tetracycline (66.67%). Fifty-five types of drug resistance patterns were detected, showing a number of drug resistance of 1-10, of which 76 strains were multi-drug resistant, accounting for 75.25%. The predominant multidrug resistance patterns were ampicillin/sulbactam-cefazolin-ampicillin-nalidixic acid (10.53%), tetracycline-ampicillin-nalidixic acid (9.21%), and ampicillin/sulbactam-ampicillin-nalidixic acid (7.89%). Conclusions Salmonella strains isolated from foodborne diseases in Longwan District were mainly detected in summer and autumn. S. typhimurium, S. enteritidis, and S. London were the predominant serotypes. The drug resistance of Salmonella to different antibacterial drugs was different, and the drug resistance spectrum showed diversity.

OBJECTIVE To explore the short-term efficacy,safety and related influencing factors of subcutaneous immunotherapy(SCIT)in children with allergic rhinitis(AR).METHODS Retrospective analyzed the clinical data of 147 children with AR who underwent SCIT at Shenzhen Hospital of Southern Medical University from August 2020 to May 2024.The clinical characteristics and laboratory parameters were collected,the visual analogue scale(VAS),total symptom score(TSS),total medication score(TMS)and combined symptom medication score(CSMS)were compared at the baseline and 3,6 and 12 months after treatment.The incidence of local adverse reactions(LRs)and systemic adverse reactions(SRs)during treatment was also documented.RESULTS A total of 147 children with AR aged 5-18 years were included in the study.A significant reduction was observed in VAS,TSS,TMS and CSMS at months 3,6 and 12 of follow up compared with baseline(all P<0.001),and the short-term onset time was months 3 after treatment.The level of VitD3 in the effective group was significantly higher than that in the ineffective group(P<0.001).Serum VitD3 level was negatively correlated with clinical symptom(R=-0.3,P=0.026).The total number of injections in 147 children was 3201.LRs occurred in 52 children(35.4％),the number of injections was 69(2.2％).SRs occurred in 21 children(14.3％),and the number of injections was 34(1.1％).No grade Ⅲ or Ⅳ SRs occurred.In the logistic regression analysis,body mass index(BMI)was a risk factor for LRs(OR:2.220,95％CI:1.009-4.887,P=0.048).CONCLUSION SCIT demonstrates significant early efficacy and a favorable safety profile safety in children with AR.Serum Vitamin D3 deficiency can affect the short-term efficacy of SCIT.Overweight and obese children are prone to develop local adverse reactions.

Objective To investigate the effect of patient's body shape and image acquisition mode on the radiation dose and image quality in percutaneous coronary angiography.Methods A total of 40 patients,who received selective percutaneous coronary angiography at the Ningbo Medical Center Lihuili Hospital of China between January 2022 and June 2023,were selected for this study.The patients were randomly divided into conventional group(including 11 males and 9 females,using coronary angiography mode to make image acquisition)and low-dose group(including 14 males and 6 females,using electrophysiological mode to make image acquisition).The patient's basic information,body size data,and the various radiation dose data were collected.The image quality rating scale for assessing the image quality was formulated.The independent sample t-test and Mann-Whitney U test were used for the comparison between the two groups.Pearson correlation analysis method was used to make correlation analysis.Results The larger the patient's chest circumference was,the higher the radiation dose would be,there was a positive linear relationship between the patient's chest circumference and the radiation dose.All the radiation dose parameters in the low-dose group were significantly lower than those in the conventional group(P＜0.01),and its reduction percentage was 48.51％-60.74％.No statistically significant difference in image quality score existed between the two groups(P＞0.0l),and in both groups the image quality was rated as good or better,meeting the requirements of intervention procedures.Conclusion In percutaneous coronary angiography the radiation dose is influenced by multiple factors including patient's body shape,image acquisition mode,exposure time,etc.Optimizing the image acquisition mode can remarkably reduce the radiation dose while maintaining the image quality and protecting the health of patients and operators.(J Intervent Radiol,2024,33:599-603)

Then the authors sorted out the existing problems of medical insurance payment for exercise prescription in China, and put forward such suggestions, as strengthening the standardized management of medical service items for exercise prescription, enhancing the enthusiasm of hospitals to apply exercise prescription, guaranteeing the seamless transition of the implementation of exercise prescription both inside and outside the hospitals, perfecting the evaluation system of the effect of exercise prescription medical service as well as advancing the medical insurance payment for exercise prescription.

Objective:To explore the application of OTD (observation, teaching and discussion) teaching combined with clinical pathway in nursing standardized training in operating room.Methods:A total of 50 nurses who were trained in the Operating Room of The First Affiliated Hospital of Air Force Medical University from August 2017 to June 2020 were selected and divided into control group and study group according to the rotation order, with 25 nurses in each group. Traditional teaching was used in the control group, and OTD teaching combined with clinical pathway was used in the study group. After the rotation training, the teaching effect was evaluated through the assessment of theoretical knowledge and clinical practice comprehensive ability, teaching satisfaction, and the satisfaction scores of participating surgeons and patients. SPSS 22.0 was used for t-test and chi-square test. Results:The results of theoretical assessment, clinical skill assessment and comprehensive ability assessment of operating room of the rotating nurses in the study group were higher than those in the control group, with significant difference ( P < 0.05). The study group was significantly better than the control group in 8 aspects, including learning initiative, stimulating learning interest, problem-solving ability, communication ability, clinical thinking ability, teamwork ability, critical thinking ability and teaching satisfaction ( P<0.05). The satisfaction scores of doctors [(94.06±2.67) vs. (92.17±2.75)] and patients [(94.90±3.22) vs. (91.25±3.10)] in the study group were significantly higher than those in the control group ( P<0.05). Conclusion:OTD teaching combined with clinical pathway can help to improve the theoretical knowledge, clinical practice comprehensive skills and teaching satisfaction of nursing students in operating room, and then improve the teaching quality.

Objective:To understand the work experiences of vaccination nurses in western China under the background of free vaccination with COVID-19 vaccine of the entire population, and provide references for these nurses to better their performance in large-scale COVID-19 vaccination.Methods:Semi-structured interviews were conducted on working experience of COVID-19 vaccination with 11 community outpatient nurses who participated in the " Second Western Immunization Planning and Health Summit Forum" held in Chongqing on April 16 to 18, 2021. The sample size was set as information saturation, and the 7-step Colaizzi analytical methods was used in data clarification and analysis.Results:Such interviews extracted three themes: difficulties and challenges, psychological experience, organization and coordination. Difficulties and challenges included shortage of nursing human resources, shortage of resources for routine vaccination, imperfect online appointments, and epidemic prevention and control risks brought by mass vaccination; psychological experience included strong sense of responsibility, accumulation of anxiety, and lack of social identity; organizational coordination included organizational and the overall integration of vaccination resources.Conclusions:Community vaccination nurses have demonstrated a high sense of responsibility and mission in the work of the COVID-19 vaccination. Software and hardware facilities should be enhanced for higher efficiency; vaccination nurses deserve more psychological assistance to help ease their tension; the localities are recommended to organize their vaccination work to fit local conditions.

Objective:To explore the association between chest high resolution CT (HRCT) scoring and prognostic factors of interstitial lung disease (ILD) in patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis (DM).Methods:The patients with DM admitted to Kailuan General Hospital between January 2017 and December 2019 were included into the study including 13 patients with positiveanti-MDA5 antibody (7 survivors, 6 deaths) and 18 patients with anti-synthase (ARS)-antibody positive. All patients underwent chest HRCT prior to treatment. The consolidation, ground-glass opacity (GGO) and fibrosis were scored to assess HRCT findings. The clinical manifestations were compared between the two groups. Cox regression analysis adjusted for age and sex was used to determine the prognostic factors for anti-MDA5 antibody-related ILD.Results:Compared with ARS patients, glutamyl transferase (GGT) and ferritin levels were significantly higher in MDA5-ILD patients [70.0(37.0, 122.5) vs 21.0(16.5, 33.5), Z=-3.37, P=0.001; 977.0(502.5, 1 366.0) vs 307.1(72.3, 546.9) , Z=-3.44, P=0.001]. The cumulative survival rate was significantly lower in patients with positive anti-MDA5 antibody than in those with positive anti-ARS antibody (100% vs 70%, P=0.001). The DM complicated with acute/subacute interstitial pneumonia (A/SIP) were found to significantly relate to death. There were no significant differences in chest HRCT scoringbetween the survivors and the deceased patients [ HR=1.08, 95% CI(0.95, 1.23), P=0.229; HR=0.97, 95% CI(0.72, 1.30), P=0.814]. Conclusion:Anti-MDA5 antibody is an important index for early diagnosis of DM complicated with acute/subacute interstitial pneumonia (A/SIP). The chest HRCT scoreis is not associated with the prognosis of anti-MDA5 antibody-related ILD patients.

Objective:To explore the effects of perianesthesia position nursing model based on enhanced recovery after surgery (ERAS) in patients undergoing thoracoscopic surgery.Methods:Totally 100 patients undergoing thoracoscopic pulmonary surgery in Huzhou Central Hospital between July and December 2019 were selected by convenient sampling and divided into the control group and the experimental group according to the random number table, with 50 cases in each group. Patients in the experimental group received perianesthesia position nursing, while patients in the control group received conventional position nursing. The time of position placement, number of placement personnel, intubation time, comfort and pain were compared between the two groups.Results:There were statistically significant differences in the placement time and number of placement personnel between the two groups ( P<0.05) . The GCQ score of the experimental group was higher, while the VAS score was lower than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The perianesthesia position nursing model based on ERAS can shorten the time of posture placement, reduce the pain, and improve the comfort in patients undergoing thoracoscopic surgery.

Objective To investigate the correlation between cumulative serum uric acid (cumUA) and brachial-ankle pulse wave velocity (baPWV).Methods Among the workers who participated in the four health check-up of Kailuan Group from 2010 to 2017,subjects who completed one PWV test were selected.The subjects who met the selection criteria were 20 688,subjects who lacked the first three uric acid tests and sex data were excluded.The subjects who had ischemic stroke (excluding lacunar infarction),transient ischemic attack and myocardial infarction were excluded.Decreased subjects were excluded and the extreme value were also excluded,20 295 subjects eventually meet the inclusion criteria and were included for statistical analysis.Stepwise linear regression,multivariate logistic regression and natural spline function were used to analyze the relationship between cumUA and baPWV and the influence of cumUA on baPWV.Results Among 20 295 subjects,the incidence of baPWV ≥ 14 m/s (criteria for judging atherosclerosis) increased with the increase of cumUA.There was significant difference in the incidence of baPWV ≥ 14 m/s (53.07％,54.35％,56.42％,58.41％,61.91％) among different cumUA partition groups (β=0.11,P＜0.01).In stepwise linear regression analysis,after adjusting for other confounding factors,it was found that cumUA was positively correlated with baPWV.In multivariate logistic regression analysis,after adjusting for other confounding factors,the results showed that baPWV ≥aPWVm were all risk factors for the third,fourth and fifth subgroups of cumUA compared with the first subgroup,and the OR05％CI) was 1.35(1.13,1.62) (P=0.01),1.60(1.29,1.97) (P＜0.01) and 2.14(1.64,2.80) (P＜0.01),respectively.Natural spline analysis exhibited a similar J curve relationship between cumUA and increased baPWV.Conclusion CumUA is a risk factor for increased baPWV.
