Objective To evaluate the effect of Ganoderma lucidum on drug resistance of the cisplantin-resistant ovarian cancer cell line(A2780CP).Methods The A2780CP cells were randomly divided into control group and test group.The cells in control group and test group were incubated in culture media alone and in culture media containing Ganoderma lucidum 0.5 mg/ml for 48 h respectively.The resistance index(RI) of A2780CP was determined by WST-1 assay.The expression of Akt,Bcl-2 and p53 protein was measured by Western blot.Results The RI was significantly deeressed,the expression of Akt and Bcl-2 protein was down-regulated,while p53 protein expression was up-regulated in test group as compared with control group(P<0.05).Conclusion Ganoderma lueidum can reduce the resistance of A2780 CP cells to cisplantin by down-regulating the expression of Akt and Bcl-2 and up-regulating p53 expression in A2780CP cells.

Objective To analyze the quality of life of patients with active rheumatoid arthritis (RA) and its relationship with other clinical and functional parameters used for the evaluation of disease activity. Methods The quality of life was assessed in 127 patients with active RA using SF-36 and was compared with non-active RA and the general population. The correlation between the quality of life and the clinical measures of disease, including morning stiffness, pain, fatigue, patient's global assessment (PGA) physician's global assessment , SJC/SJ1, TJC/TJI, DAS28, HAQ were measured. Results The patients with active RA reported significantly decreased scores in all dimensions of SF-36. Fatigue, PGA, physician's global assess-ment, DAS28 and HAQ significantly correlated with the scores in all dimensions of SF-36. Pain was correlated with the scores in all dimensions of SF-36 except RE. TJI was correlated with six dimensions. TJC was correlated with five dimensions. ESR was correlated with three dimensions. Conclusion The quality of life in patients with active RA is significantly declined compared with non-active RA and the general population. Disease activity and functional status of patients with active RA is closely correlated with the quality of life.

Objective To investigate the prevalence of fatigue in rheumatoid arthritis (RA) and its relationship with other clinical and functional parameters used for the evaluation of disease activity and health related quality of life. Methods The fatigue was assessed in 230 patients with RA using visual analogue scale (VAS). The correlation between fatigue and the clinical disease activity including morning stiffness, pain, PGA, physician's global assessment, TJC, TJI, SJC, SJI, DAS28, HAQ and health-related quality of life were assessed. Results The prevalence of fatigue was 85.7% and the fatigue score of 51.7% patients was higher than 50 mm. After controlled for the possible confounding factors such as age, gender and disease duration, it was found that fatigue was highly correlated with pain, disease activity, functional disability, physical health and mental health. Conclusion Fatigue is an important symptom of RA and is correlated with pain, disease activity, functional disability and health-related quality of life.

Objective To investigate the feasibility and safety of surgical device closure of doubly committed sub-arterial ventricular septal defect via left sub-axillary.Methods A total of 45 patients diagnosed as doubly committed sub-arterial ventricular septal defect (dcVSD) with transthoracic echocardiography (TTE) and transesophageal echocardiography(TEE) were enrolled from June 2014 to August 2016 in Henan Children Heart Center,Henan Provincial People's Hospital.There were 39 males and 6 females,with the mean age of (2.2 ±2.1) years old(0.5-8.0 years),the body weight (13.8 ± 7.1) kg(7.0-34.1 kg),the defect size (4.5 ± 1.0) mm (3.0-8.0 mm).After general anesthesia,the patients were in supine and evaluated by TEE which indicated whether they were fit to closure.Then,they were turned to the right lateral position while this technique was determined.A vertical incision of 2-3 cm was made between the third and the fifth intercostal space and invasion in thoracic space via fourth intercostal space.Puncture was done at the anterior surface of right ventricular outlet tract to build a delivery tract.The occluder was released and the VSD was occluded under transesophageal echocardiography guidance.Results Forty-one patients had a successful surgical dcVSD closure with asymmetric occluders sized (6.0 ± 1.5) mm(4-10 mm).Among 4 failure cases,2 cases (4.4％) were switched to open-heart surgical repair,1 case (2.2％) due to device related aortic regurgitation,the rest 1 case (2.2％) experienced a dislocation of occluder into pulmonary artery and was converted to surgical repair after retrieve of occluder.Trivial residual shunt was detected in 2 cases (4.4％) postoperatively,a spontaneous closure was observed by 1 month follow-up and 3 months follow-ups,respectively.All the patients were discharged 5 to 8 days after the operation.With a follow-up of (10.4 ±5.0) months [3-24 months],there were no complications such as pericardial effusion,displacement of device,atrioventricular block or new valvular dysfunction.Conclusions Minimally invasive device closure of doubly committed sub-arterial ventricular septal defect via left sub-axillary is a feasible and safe treatment for closure of dcVSD.This technique has advantages of minor wound,less exudation,covert incision,however,long term follow-up is necessary.

Objective:To investigate the effects of human placenta tablets combined with active folic acid and compound nutrient tablets on Th1 cytokines and hormone levels in pregnant patients with threatened miscarriage.Methods:A total of 226 pregnant patients with threatened miscarriage who received treatment in Linyi Traditional Chinese Medicine Hospital from April to September 2021 were included in this study. They were randomly divided into a control group and an observation group, with 113 patients in each group. The control group was treated with human placenta tablets. The observation group was treated with human placenta tablets combined with active folic acid and compound nutrient tablets. All patients were treated for 4 weeks. Before and after treatment, serum levels of Th1 cytokines, β-human chorionic gonadotropin, progesterone, and estradiol as well as the rate of success of protection against miscarriage, adverse reactions, and perinatal complications were compared between the two groups.Results:After 4 weeks of treatment, serum levels of interleukin-2, tumor necrosis factor-α, and interferon-γ in the observation group were significantly lower than those in the control group ( t = 27.53, 20.99, 31.69, all P < 0.001). Serum levels of β-human chorionic gonadotropin, progesterone, and estradiol in the observation group were (143.79 ± 9.56) IU/L, (36.43 ± 4.71) ng/L, (234.72 ± 13.29) pmol/L, which were significantly higher than (122.53 ± 7.47) IU/L, (29.32 ± 4.22) ) ng/L, (167.86 ± 8.93) pmol/L in the control group ( t = 18.63, 11.95, 44.39, all P < 0.001). The rate of success of protection against miscarriage in the observation group was significantly higher than that in the control group (92.9% vs. 76.1%, χ2 = 12.20, P < 0.05). There were no significant differences in the incidences of adverse reactions and perinatal compilations between the two groups (both P > 0.05). Conclusion:Human placenta tablets combined with active folic acid and compound nutrient tablets can improve serum levels of Th1 cytokines and hormones, and increase the rate of success of protection against miscarriage, without increasing the incidences of adverse reactions and perinatal complications.

Objective? To establish a digital protection system for incontinence-associated dermatitis based on earlier prevention to reduce the incidence of incontinence-associated dermatitis. Methods? Based on the informationization of nursing platform, we run the digital protection system module of incontinence-related dermatitis based on the forward moving of the prevention gateway in Zhejiang Provincial People＇s Hospital. Through comparative study, 108 patients with incontinence and incontinence-related dermatitis from January to March 2018 were randomly selected as the pre-operation data, and 108 patients with incontinence and incontinence-related dermatitis from January to March 2019 as the post-operation data. The nurses of the two groups were observed and compared in terms of their assessment accuracy in patients＇ incontinence risk, position and Incontinence Associated Dermatitis Severity(IADS), clinical staging, and implementation of prevention strategies. Meanwhile, the incidence of incontinence-related dermatitis among all inpatients in the hospital from January to March in 2018 was compared with the same period of 2019. Results? After the operation of the digital protection system for incontinence-related dermatitis based on earlier prevention, the nursing staff's accuracy rate in the risk assessment of incontinence (χ2=38.095,P＜0.01), IADS (χ2=64.901,P＜0.01), clinical staging accuracy (χ2=42.424,P＜0.01) and the implementation of protective measures (χ2=50.000, P＜0.01) had significant statistical differences. The incidence of incontinence-related dermatitis in hospitalized patients decreased from 0.35% before operation to 0.06% after operation with statistical significance(χ2=41.031, P＜0.01). Conclusions? The operation of the digital protection system for incontinence-associated dermatitis based on earlier prevention can reduce the incidence of incontinence-associated dermatitis and improve the prevention and management competence of nursing staff.

Objective To investigate the effects of esketamine on hypoxic-ischemic myocardial injury in neonatal rats based on glycogen synthase kinase-3β/NOD-like receptor thermal protein domain-containing protein 3 (GSK-3β/NLRP3) pathway. Methods Thirty neonatal rats were randomly divided into sham operation group, model group and esketamine group, with 10 rats in each group. The rats in the sham operation group underwent a median incision in the neck to expose the bilateral common carotid arteries; the rats in the model group and the esketamine group underwent ligation of the common carotid arteries combined with a hypoxic environment to establish a model ofischemia and hypoxia; the rats in the esketamine group were given esketamine intervention (50 mg/kg). Left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), serum creatine kinase isoenzyme (CK-MB), cardiac troponin I (cTnI), lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1β levels, myocardial injury, myocardial cell apoptosis and apoptosis protein caspase 1/3/9 levels, neutrophil infiltration in myocardial tissue, and changes in GSK-3β and NLRP3 protein levels in myocardial tissue were detected in each group. Results Compared with the sham operation group, the LVEF and LVFS were significantly decreased and the LVEDD and LVESD were significantly increased in the model group, while the LVEF and LVFS were significantly higher and the LVEDD and LVESD were significantly lower in the esketamine group than in the model group (P < 0.05). The serum levels of CK-MB, cTnI, LDH, TNF-α, IL-6, IL-1β, myocardial injury and apoptosis, caspase 1/3/9 protein levels in myocardial tissue sections, neutrophil counts, and GSK-3β and NLRP3 protein levels were significantly increased in the model group, and these indicators were significantly lower in the esketamine group than in the model group (P < 0.05). Conclusion Esketamine improves hypoxic-ischemic myocardial injury in neonatal rats by inhibiting inflammation, and its mechanism of action is related to the GSK-3β/NLRP3 pathway.

Objective:To analyze common respiratory pathogens epidemiology in hospitalized children with lower respiratory tract infection (LRTI) in a single center in Shanghai, and to provide the basic data support for clinical diagnosis and treatment of children with LRTI in Shanghai.Methods:Children with LRTI in Children′s Hospital of Fudan University were enrolled from January 1, 2015 to December 31, 2019, and respiratory samples were collected and tested by direct immunofluorescence assay and real time polymerase chain reaction. The epidemiological characteristics of different respiratory pathogens were analyzed. Chi-square test was used for statistical analysis.Results:A total of 18 716 children were included, the total detection rate of respiratory pathogens was 36.96% (6 918/18 716), and the most frequent detected pathogen was Mycoplasma pneumoniae (MP) (15.31%(2 866/18 716)), followed by respiratory syncytial virus (RSV) (10.40%(1 946/18 716)) and parainfluenza virus Ⅲ (PIV-Ⅲ) (4.65%(871/18 716)). The detection rate of pathogens in female was significantly higher than that in male (38.48%(2 936/7 630) vs 35.92%(3 982/11 086), χ2=12.72, P<0.001). RSV and influenza virus A (Flu-A) infections peaked in winter. The detection rates of influenza virus B (Flu-B) and human metapneumovirus (MPV) were higher in winter and spring. PIV-Ⅲ infection peaked in spring and summer. The peak of PIV-Ⅱ infection occurred in summer and autumn. The infections of adenovirus (ADV), MP, Chlamydia trachomatis (CT) and PIV-Ⅰ were prevalent throughout the year without significant seasonality. The detection rate of RSV declined with age, while the detection rate of MP increased with age. The co-infection rate was 1.65%(309/18 716), and the predominant co-infection type was MP and RSV (0.37%(70/18 716)). Conclusions:A variety of pathogens lead to children′s LRTI in Shanghai from 2015 to 2019, with the common infection of MP, RSV and PIV-Ⅲ. Different pathogens showed different epidemiological characteristics in age and season distributions.
