OBJECTIVE:To study the inhibitory effects of ampelopsin sodium (AMP-Na) combined with carboplatin on the proliferation of Lewis cell of lung cancer. METHODS:6.25,12.5,25,50 and 100 μg/ml AMP-Na and 3.125,6.25,12.5,25 and 50 μg/ml carboplatin were used to culture the cells for 4 h,and the cell viability was determined and the inhibition rate and half in-hibition concentration(IC50)were calculated. 12.5,25,50 and 100 μg/ml AMP-Na and 12.5 μg/ml carboplatin were used to culture the cells for 12 h,and the flow cytometry was used to determine the expression of Caspase-3. RESULTS:AMP-Na with serial con-centrations combined with carboplatin with serial concentrations had obvious inhibitory effects on the cell proliferation. With the in-crease of mass concentration,the IC50 of carboplatin on the Lewis cells was gradually decreased;when the AMP-Na of 6.25-50μg/ml was combined with carboplatin of 3.125-25 μg/ml,it showed the strongest inhibitory effects on the Lewis cell proliferation. When cells were cultured with AMP-Na and carboplatin for 24 h,the expression of Caspase-3 increased significantly. CONCLU-SIONS:AMP-Na combined with carboplatin has synergistic inhibitory effect on the Lewis cell proliferation by a mechanism that may be related to the apoptosis induced by Caspase-3 activated by AMP-Na.

Objective:To explore the effect of therapeutic communication on infusion safety, disease uncertainty, coping styles, anxiety and depression in patients with emergency infusion.Methods:A total of 126 patients treated with infusion patients in emergency department in Jiangsu Provincial People's Hospital, the First Affiliated Hospital of Nanjing Medical University from July 2019 to December 2019 were selected and divided into two groups by random digits table method with 63 cases in each group. Patients in the control group received routine nursing, and patients in the intervention group received therapeutic communication nursing intervention on this basis. The incidence of adverse events of infusion during the intervention of the two groups of patients was observed. The disease uncertainty, coping styles, anxiety and depression were evaluated by Mishel's Uncertainty in Illness Scale (MUIS), Medical Coping Mode Questionnaire (MCMQ), Self-rating Anxiety Scale (SAS) and Self-rating Depressive Scale (SDS) before and after intervention.Results:The final collection of 109 patients with complete questionnaire, the recovery rate was 86.51% (109/126), including 55 cases in the intervention group, 54 cases in the control group. The incidence of adverse events of infusion was 16.36%(9/55) in the intervention group and 29.63%(16/54) in the control group, and there was significant difference( χ2 value was 5.057, P<0.05). There was no significant difference in the score of MUIS, MCMQ, SAS, SDS before the intervention between the two groups ( P>0.05). After the intervention, the uncertainty, unpredictability, lack of information and complexity dimension of the intervention group patients' MUIS scores were respectively (17.76 ± 2.49), (12.03 ± 2.51), (11.82 ± 2.12), (11.74 ± 2.24), which were lower than those in the control group (24.72 ± 2.94), (16.31 ± 2.27), (16.13 ± 2.51), (15.39 ± 2.31), the differences were significant( t values were -13.346- -8.375, P<0.05). The confront score of the intervention group patients' MCMQ was (19.13 ± 2.62) higher than that in the control group(13.79 ± 1.96), the avoidance and yield scores were respectively (8.71 ± 1.34), (9.81 ± 1.17), which were lower than those in the control group (14.57 ± 1.93), (15.12 ± 1.86), the differences were significant( t values were 12.031, -18.441, -17.875, P<0.05). The scores of SAS and SDS in the intervention group were (29.43 ± 3.62), (27.67 ± 3.11) respectively, which were lower than those in the control group (37.44 ± 5.31), (40.12 ± 4.92), the differences were significant( t values were -9.216, -15.821, P<0.05). Conclusions:Therapeutic communication can reduce the risk of emergency infusion, reduce the uncertainty of patients to the disease, improve patients' countermeasures to the disease, relieve patients' anxiety and depression, and improve the nursing quality of emergency infusion patients.

ObjectiveTo study the characteristics in negative energy balance in different-aged patients with metabolic syndrome (MS) and come out with nursing countermeasures.Methods Twenty-four hour dietary data reviewing and the international physical activity questionnaire were used to investigate energy intake and consumption among 384 MS patients.The fat content,fat percentage and lean body mass were measured by the human body composition analyzer.Body mass index (BMI),waist/height,fat percentage,lean body mass,energy intake and energy consumption were compared between different ages and sexes.Results In the group aged over 51 years,the waist/height of female MS patients was significantly smaller than their male counterparts (P<0.05).For all groups of different ages,the percentage of fat in the female patients was significantly larger,their lean body mass was less(P<0.01), their intake of energy was significantly lower than that of the males (P<0.05).The intake of energy among the male patients at the group aged 21~30was significantly larger than the males of other age groups and so it was with the energy intake of the males aged 21-70 years as compared to the males aged 71~80 years (P<0.05).Conclusion Education on disease knowledge should be strengthened among healthy people so as to realize the negative energy balance based on the rate of waist/height,body composition,energy intake and energy consumption,which is of great significance for the prevention and control of metabolic syndromes.

Objective To explore a method of subsection adjustment for the proportion of three capacity nutrients in patients with metabolic syndrome (MS).Methods Totally 334 MS patients who were diagnosed in the physical examination center and the department of endocrinology and nutrition of Xi'an Central Hospital Affiliated to Xi'an Jiaotong University of School of Medicine were enrolled in this study.According to calculator random digital method,the patients were divided into intervention group (n=168) and the control group (n=166).The energy of two groups were calculated according to the following formula,y =13.5-0.025x1 + 0.215x2-0.006x3+0.342x4-0.268x5+0.623x6 (x1:age,x2:activity intensity index,x3:waist circumference,x4:environmental temperature,x5:BMI,x6:sex).The limit of daily energy was set to 5.02-7.53 MJ.The proportion of the three major nutrients for energy was adjusted of different energy segments of intervention group.When the daily energy was 5.02 MJ,the protein energy ratio was 30％,and the energy increased by 0.42 MJ per time while the protein energy supply ratio was reduced by 2.5％.The energy ratio of carbohydrate was 40％,and the energy increased 0.42 MJ per time while the energy ratio increased by 2.5％.The energy ratio of fat was 30％ on various stages of energy supply.The energy proportions of the three major nutrients in the control group were as follows:protein 15％,fat 25％,and carbohydrate 60％.Results After the intervention by 6 months,the 2-hour postprandial blood glucose of intervention group decreased from (9.22±5.57) mmol/L to (6.05±4.68) mmol/L,the hemoglobin A 1 c decreased from (6.79 ± 1.12) ％ to (5.56± 1.32) ％,and the triglyceride decreased from (3.14±1.73) mmol/L to (1.72±1.17) mmol/L.There was significant difference compared with those in control group (P =0.000,0.027,0.034).Conclusion The proportions of the three major nutrients in MS can remarkably improve the glucose and lipid metabolism in MS patients.

Objective To understand the characteristics and relation of clinical stage and outcome of severe cases on hand,foot and mouth disease (HFMD) and to establish the evaluation method for understanding severity of this disease.Methods According to factors as geographical location,economic and epidemic levels,five provinces (Henan,Shandong,Yunnan,Zhejiang and Sichuan provinces) were selected.Reported severe cases of HFMD from the National Notifiable Diseases Reporting System were selected randomly in the five provinces.Basic epidemiological information,clinical data,and pathogen testing results in the involved hospitals were collected.Clinical stages on all the patients were decided in accordance with "the clinical expert consensus on diagnosis and treatment for severe case of enterovirus type 71 (EV71) infections (2011 edition)".Data were analyzed using SPSS software 18.0 and other epidemiological methods.Results A total of 657 severe HFMD cases were investigated,with 326 cases positive of EV71,accounting for 91.3％ (326/357) among all the laboratory-confirmed cases.Of the 657 cases,542 cases (82.5％,95％CI:79.4％-85.3％) were diagnosed as in stage 2 (with nervous system involvement),99 cases (15.1％,95％CI:12.4％-18.0％) in stage 3 (early phase of function failure on heart and lung),and 16 cases (2.4％,95％CI:1.4％-3.9％) were in stage 4 (function failure of heart and lung).11 cases (1.7％,95％CI:0.9％-3.0％) were with squeal when discharged from hospital with 8 cases (1.2％,95％CI:0.6％-2.3％) died.When comparing the proportions among stage 2,stage 3 and stage 4,significant differences were found between age groups (x2=22.632,P=0.012).The younger the patient was the lower the proportions of stage 2 and the more proportion of stage 3 appeared.When comparing the proportions of clinical stages among the five provinces,significant differences (x2=41.481,P =0.000) were noticed.Proportions of different clinical stages in gender,ethnicity,occupation,place of residence types and the type of pathogen appeared no significant differences,respectively.However,the proportions of squeal and death in stage 2,stage 3 and stage 4 showed significant differences (sequela:x2=12.960,P=0.001;Death:x 2=16.850,P=0.001),respectively.Conclusions The pcrccntage of clinical stages of severe HFMD patients related to the rate of squeal and death.Clinical staging can be used for assessing the clinical severity of complications and the effectiveness of treatment,of HFMD.

China has classified the Corona Virus Disease 2019(COVID-19) as a statutory category B infectious disease and managed it according to Category B since January 8, 2023.In view that Omicron variant is currently the main epidemic strain in China, in order to guide the treatment of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection in children with the times, refer to the Diagnosis and Treatment Protocol for Novel Coronavirus Infection (Trial 10 th Edition), Expert Consensus on Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fourth Edition) and the Diagnosis and Treatment Strategy for Pediatric Related Viral Infections.The Expert Consensus on the Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fifth Edition) has been formulated and updated accordingly on related etiology, epidemiology, pathogenic mechanism, clinical manifestations, auxiliary examination, diagnosis and treatment, and added key points for the treatment of COVID-19 related encephalopathy, fulminating myocarditis and other serious complications for clinical reference.

Nasopharyngeal carcinoma (NPC) is the third most common malignancy with a high recurrence and metastasis rate in South China. Natural compounds extracted from traditional Chinese herbal medicines have been developed and utilized for the treatment of a variety of cancers with modest properties and slight side effects. Maackiain (MA) is a type of flavonoid that was first isolated from leguminous plants, and it has been reported to relieve various nervous system disorders and exert anti-allergic as well as anti-inflammatory effects. In this study, we demonstrated that MA inhibited proliferation, arrested cell cycle and induced apoptosis in nasopharyngeal carcinoma CNE1 and CNE2 cells in vitro and in vivo. The expression of the related proteins associated with these processes were consistent with the above effects. Moreover, transcriptome sequencing and subsequent Western blot experiments revealed that inhibition of the MAPK/Ras pathway may be responsible to the anti-tumor effect of MA on NPC cells. Therefore, the effects of MA and an activator of this pathway, tertiary butylhydroquinone (TBHQ), alone or combination, were investigated. The results showed TBHQ neutralized the inhibitory effects of MA. These data suggest that MA exerts its anti-tumor effect by inhibiting the MAPK/Ras signaling pathway and it has the potential to become a treatment for patients with NPC.
