ABSTRACT
Objective:To investigate the status and the influencing factors of influenza vaccination during the COVID-19 pandemic among community-dwelling elderly in Shanghai.Methods:A questionnaire survey on influenza vaccination among community-dwelling elderly was conducted in Shanghai Taikang elderly community in November 2020. The information on demographic characteristics, reasons for refusal of vaccination, and measures for increasing vaccination rates were collected. Multiple logistic regression was used to analyze the correlation between influenza vaccination and sociodemographic and health-related characteristics.Results:Among 520 respondents, the vaccination rate was 30.58% (159/520). Compared with unvaccinated group, elderly in vaccinated group was older ( t=16.04, P=0.003)and more educated(χ2=8.16, P=0.043). The elderly with comorbid heart disease, chronic obstructive pulmonary disease, tumor, asthma, Parkinson′s disease were likely to have vaccination ( OR=1.45, 2.16, 1.23, 1.64, 5.83; all P<0.05).The reasons for the elderly not to be vaccinated were concerns of side effects (46.26%, 167/361), lack of doctors′ recommendations (24.10%, 87/361), and unnecessary for people with good health conditions (19.39%, 70/361). The independent factors of influenza vaccine awareness rate were healthcare providers′ recommendations ( OR=9.18, 95% CI:5.47-16.32), vaccination at home( OR=11.79, 95% CI:6.87-21.66),vaccination available in community( OR=8.08, 95% CI:8.08-15.45),the mandatory requirement ( OR=4.61,95% CI:4.61-10.11),free of charge( OR=7.48, 95% CI:4.08-15.12). Conclusion:Influenza vaccination coverage among the elderly in Shanghai is still low even during the COVID-19 pandemic. Policy interventions, awareness education and strengthening the primary healthcare resources may contribute to achieving a high influenza vaccine coverage rate in the community-dwelling elderly
ABSTRACT
Objective:To explore the effect of nutritional status on pulmonary infection in patients with severe stroke, and to identify the nutrition-related risk factors of pulmonary infection, so as to provide reference for the prevention and treatment of pulmonary infection from the perspective of nutrition.Methods:The clinical data of 122 patients admitted to the neuro-intensive care unit (NICU) of the First Affiliated Hospital of Chongqing Medical University from August 2019 to February 2020 were retrospectively analyzed. Patients with severe stroke were divided into two groups according to whether they had pulmonary infection during hospitalization in NICU, and there were 25 patients in case group and 97 patients in control group. Nutritional Risk Screening (NRS2002), Nutrition Risk in the Critically ill (NUTRIC) score and malnutrition criteria, combined with anthropometry, clinical comprehensively history and laboratory data were used to evaluate the nutritional status of patients. Logistic regression was used to identify nutrition-related risk factors for pulmonary infection in patients with severe stroke.Results:The incidence of pulmonary infection in severe stroke patients was 20.5% (25/122). Univariate analysis showed that the difference of chronic obstructive pulmonary disease, endotracheal intubation, nasogastric tube use, NUTRIC ≥ 5, the Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ, Sequential Organ Failure Assessment (SOFA), Glasgow Coma Scale (GCS), and creatinine levels, duration of enteral nutrition, length NICU stay, and length of hospital stay between the two groups were statistically significant ( χ2 value was 7.542-34.403, t value was 2.207, Z value was -3.511, 3.083 and 3.115, P<0.05 or 0.01). Multivariate Logistic regression analysis showed that NUTRIC≥5 ( OR= 12.202, 95% CI 2.342-63.568) and nasogastric tube use ( OR=16.990, 95% CI5.343-54.024) were independent risk factors of pulmonary infection in patients with severe stroke ( P<0.01). Conclusions:NUTRIC score≥ 5, high nutritional risk and nasogastric tube use were independent risk factors of pulmonary infection in patients with severe stroke, which should be given early nutritional assessment and individualized care.
ABSTRACT
Objective To observe the clinical characteristics in schoolchildren diagnosed with allergic rhi-nitis(AR)and nonallergic rhinitis(NAR)three years ago,and to compare the prevalence of asthma and chronic cough among them and the impacts of AR and NAR on the quality of life. Methods Totally 146 AR children and 108 NAR ones diagnosed between September 2013 and March 2014 were surveyed using a questionnaire by tele-phone and all the children were not complicated with chronic cough and asthma. The statistical analysis was per-formed by a professional statistician using SPSS 12.0 statistical software. Results A total of 111 questionnaires were completed in AR group and 76 in NAR group. The prevalence of asthma was 11.7%(13/111)in AR group while 6.6%(5/76)in NAR group and there was no statistically significant difference(χ2=1.366,P=0.242). The prevalence of chronic cough was 26.1%(29/111)in AR group and 13.2%(10/76)in NAR group and there was sta-tistically significant difference(χ2=4.596,P=0.032). The score of rhinitis visual scale(VAS)and rhinoconjunc-tivitis quality of life questionnaire(RQLQ)was significant higher in AR group than that in NAR group(t = 2.570 and 2.467,P=0.012 and 0.016). Conclusions Children with NAR may also have the risk for the development of asthma as those with AR. The prevalence of chronic cough is higher in children with AR than in those with NAR. AR might bring more impacts on children′s quality of life than NAR.
ABSTRACT
Objective To understand the current development situation and the existing problems and deficiencies of the exercise cardiopulmonary rehabilitation development in Level 2 and above the general hospitals in Chongqing, and to analyze and find out the factors restricting the development of cardiopul-monary rehabilitation in Chongqing, and put forward suggestions for reform and development. Methods Through literature research, field visits and questionnaire survey, the condition of 115 Level Two compre-hensive hospital's rehabilitation and exercise cardiopulmonary rehabilitation development in Chongqing was understood. Among them, 500 questionnaires were sent to 6 hospitals concerned with cardiopulmonary rehabilitation service, and 483 questionnaires were received with 351 valid questionnaires. Epidata3.1 and SPSS 13.0 statistical software were used to gather research data. Results The settings rate of 115 secondary general hospital rehabilitation was 41.7％, while only 6 hospitals carried out cardiac rehabilitation and cardio pulmonary rehabilitation. There were few rehabilitation beds, the basic staffing was inadequate and the medical staff ratio was only 2 to 2.6. Besides, there is a severe shortage of full-time health instructors.Conclusion The clinical sports cardiopulmonary rehabilitation in Chongqing is as following: The construc-tion of hospital related policies is lagging behind, the overall development of rehabilitation therapy is unbal-anced, the development is late and the level of operation is low. While the lack of professional health movement means that instructors and medical staff have cognitive impairment, residents have low accep-tance of sports rehabilitation therapy and there are insufficient pathogens, which are the main factors that restrict the development of cardiopulmonary rehabilitation.
ABSTRACT
Objective To investigate the role of epidermal growth factor receptor 3 (ErbB3) and insulin-like growth factor-1 receptor (IGF1R) in enhancing the resistance of Herceptin in human breast cancer.Methods HRG (Heregulin,the ligand of ErbB3) or IGF2 (insulin-like growth factor2,the ligand of IGF1R) was correspondingly added into breast cancer cells SKBR3 and BT474,and then 3-(4,5-dimenthylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay and were performed in these cells to evaluate the sensitivity of these cells to Herceptin.Furthermore,we used HRG or IGF2 antibodies to inhibit their joint receptors in Herceptin-resistant breast cancer cells SKBR3/POOL2 and BT474/HR20.Finally,the sensitivity of these treated cells to Herceptin was detected via MTS assay.HRG or IGF2 was added into breast cancer cell BT474,and co-IP assay was used to detect the expressions of ErbB3 and IGF1R which combined with ErbB2.Results The treatment groups used HRG or IGF2 enhanced the resistance of Herceptin in Herceptin-sensitive breast cancer cells.On the other hand,we used antibodies of HRG and IGF2 to block their combining with their receptors in Herceptin-resistant breast cancer cells,the cells became more sensitive to Herceptin.BT474 cell was treated with HRG or IGF2.The expressions of ErbB3 and IGF1R which combined with ErbB2 were increased.Conclusions The formation of heterodimers ErbB2/ErbB3 and ErbB2/IGF1R might enhance the resistance of Herceptin in ErbB2-overexpression human breast cancers.
ABSTRACT
Objective To explore the application effect of strengthened pulmonary rehabilitation exercise in lung cancer patients with severe pulmonary ventilation dysfunction during perioperative period. Methods A total of 96 patients receiving lung cancer radical treatment under thoracoscope in our hospital during March 2013 to April 2015 were collected, and for all these patients, pulmonary function test before treatment showed that there was severe pulmonary ventilation dysfunction. The patients were divided into the routine group and the intervention group by random digital table method, with 48 patients in each group;patients in the routine group received routine perioperative nursing, and those in the intervention group received the strengthened pulmonary rehabilitation intervention plan; change in pulmonary function before treatment, duration of mechanical ventilation, time of oxygen therapy, retaining time of chest tube, length of hospital stay and occurrence of complications after treatment were compared between the two groups. Results After strengthened pulmonary rehabilitation intervention in the intervention group, the FVC was (2.63±0.47) L, the MVV was(53.14±9.40) L, the DLCO was(19.26±2.63) ml·min-1·mmHg-1, the VO2 was (23.15±4.36) ml/kg and the O2Pulse was(10.98±2.52) ml·min-1·times-1, Which were significantly improved compared with those before treatment, (2.41±0.40) L,(46.98±8.91) L,(17.56±2.83) ml·min -1·mmHg -1, (20.17±4.35)ml/kg and(9.82±2.07) ml·min-1·times-1, t=2.521, 3.512, 3.112, 3.421, 2.515, P<0.01 or 0.05. While there was no obvious change in the above- mentioned indexes of those in the routine group. After treatment of patients in the intervention group the duration of mechanical ventilation was (9.42±3.17) hours, time of oxygen therapy was (76.23±21.18) hours, retaining time of chest tube was (3.58±1.44) days and length of hospital stay was (6.62±2.14) days, which were significantly shorter than those in the routine group, (17.29±4.79) hours,(92.14±24.29) hours, (4.73±2.15) days and(8.68±2.96) days. The occurrence rates of complications such as pulmonary infection, pulmonary atelectasis and respiratory failure were 12.50%(6/48),10.42%(5/48) and 4.17%(2/48)in the intervention group, significantly lower than those in the routine group, 41.67%(20/48),29.17%(14/48) and 18.75%(9/48), χ2=10.338, 5.315, 5.031, P <0.01 or 0.05. Conclusions Strengthened pulmonary rehabilitation intervention can improve pulmonary function of lung cancer patients with severe pulmonary ventilation dysfunction before treatment, reduce the occurrence rate of post- operative complications and enhance safety during the perioperative period; it is worth of being further promoted clinically.
ABSTRACT
BACKGROUND:Previous studies have demonstrated that total saponins of panax notoginseng can inhibit the ethanol-induced adipogenic differentiation of rabbit bone marrow stromal cells and confirmed that total saponins of panax notoginseng promoted the proliferation and differentiation of rabbit osteoblasts, and improved the osteoprotegerin mRNA relative expression in osteoblasts so as to inhibit receptor activator of nuclear factor kappa B ligand mRNA expression. OBJECTIVE:To observe effects of total saponins of panax notoginseng on the ultrastructure of the rabbit models of alcoholic avascular necrosis of the femoral head. METHODS:New Zealand rabbit models of alcohol-induced avascular necrosis of the femoral head were established by gavage of spirit. Successful rabbit models were separately injected with saline, compound bone peptide and total saponins of panax notoginseng group, 0.1 mL/kg, once a day, for 4 consecutive weeks. The ultrastructure of each group were observed by transmission electron microscope. RESULTS AND CONCLUSON:Transmission electron microscopy showed that osteocytes after alcoholic avascular necrosis of the femoral head presented mitochondrial swel ing and fuzzy crista structure, and degranulation of polysomes on rough endoplasmic reticulum. Lipid droplets were seen in osteocytes. Compared with saline group, mitochondria swel ing subsided, cristae appeared, the number of polysomes increased on rough endoplasmic reticulum, but the number of lipid droplet decreased in total saponins of panax notoginseng group. Morphological changes in ultrastructure were similar between compound bone peptide group and total saponins of panax notoginseng group. Morphological changes in ultrastructure were more significant in the total saponins of panax notoginseng and compound bone peptide groups compared with saline group (P<0.05). Results verified that total saponins of panax notoginseng could effectively restore ultrastructure of osteocytes of rabbit models of alcoholic avascular necrosis of the femoral head in the early stage.
ABSTRACT
Pain is one of the common symptoms of cancer which seriously affects the quality of life of the patients. Cancer pain is mainly treated with the three-step method, biological therapy or nerve block therapy based on antitumor therapy. However, up to 50 percent of patients with cancer-related pain do not receive adequate pain relief, affecting their physical and psychological well-being, and leading to a lower quality of life for the patient after conventional treatment. Clinical observation suggests that traditional Chinese medicine may alleviate cancer-related pain either by oral administration, topical administration, acupuncture or other means with continuing non-addictive and non-drug-resistant qualities. However, scientific evaluation of the efficacy of herbs in the treatment of pain is insufficient; the underlying mechanisms are unclear and, safety and toxicity remain a concern.
