Objective:To evaluate the effect of continuous pump ropivacaine in rectus sheath in the postoperative analgesia after abdominoplasty.Methods:Patients with abdominoplasty who were admitted to the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from August 2020 to December 2021 were retrospectively analyzed. They were divided into 2 groups: the control group received patient-controlled intravenous analgesia (PCIA) after the operation, sufentanil 100 μg + normal saline diluted to 100 ml, the rate was 2 ml/h, lasted for 48 h, locking time 15 min, Bolus: 0.5 ml; the study group underwent postoperative rectus abdominis intrathecal intubation and continuously infused 0.262 5% ropivacaine saline mixture 100 ml, the rate was 2 ml/h, lasted for 48 h, the locking time is 15 min, Bolus: 0.5 ml. The method of catheter placement in the study group: a catheter was placed unilaterally in the anterior sheath of the rectus abdominis under direct vision, and an incision was made 2 cm below the umbilical plane. The other end is pierced from the umbilicus and connected to the analgesic pump. The visual analogue scale (VAS) for pain and the number of analgesic pump boluses at 24 h and 48 h after operation, the occurrence of postoperative adverse drug reactions and the patient satisfaction at 1 month after operation were collected. The normally distributed measurement data were expressed as Mean±SD, and the comparison between the two groups was analyzed by t-test; the count data was expressed by the frequency (percentage), and the Fisher’s test was used for analysis. Results:A total of 56 patients were included, including 9 males and 47 females, ranging in age from 27 to 53 years old, with ASA graded from 1 to 2, body mass index (BMI) ranged from 26 to 33 kg/m 2. Their rectus abdominis separation ranged from 3 to 7 cm. Compared with the control group, the pain VAS score of the study group at 48 hours after the operation was lower (3.9±1.5 vs. 5.2±1.4, P<0.05), and the number of analgesic boluses was reduced (2.9±0.3 vs. 3.9±0.4, P<0.05), the incidence of adverse reactions such as nausea, vomiting decreased( P<0.05). The satisfaction rate 1 month after operation in the study group was significantly higher than that in the control group [100.0% (30/30) vs. 42.3% (11/26), P<0.05]. Conclusions:Continuous infusion of ropivacaine through anterior rectus intrathecal cannula can effectively relieve abdominal pain after total abdominoplasty, reduce adverse reactions caused by postoperative analgesics, improve patient comfort during hospitalization, and improve overall surgical satisfaction.

ERK pathway regulated the programmed death ligand-1 (PD-L1) expression which was linked to the response of programmed death-1 (PD-1)/PD-L1 blockade therapy. So it is deducible that ERK inhibitor could enhance the efficacy of PD-1 inhibitor in cancer immunotherapy. In this study, PD0325901, an oral potent ERK inhibitor, strongly enhanced the efficacy of PD-1 antibody

Objective To investigate the change of the nutritional status of elderly patients in Chinese major hospitals dynamically with nutritional risk screening 2002 (NRS 2002) and subjective global assessment (SGA) during hospitalization.Methods A prospective,multi-center survey was conducted on over 65 years old patients who were admitted in departments of gastroenterology,respiratory medicine,general surgery,geriatrics,thoracic surgery,neurology,orthopedics and medical oncology of 9 large hospitals in China for 7-30 days between June 2014 and September 2014.On admission and within 24 hours after discharge,the clinical data were recorded,physical indices were measured,and laboratory examination were conducted.NRS 2002 and SGA were used to make an evaluation.The nutritional supports and clinical outcomes were also recorded and then the correlation between nutritional status and clinical outcomes were analyzed.Results A total of 2558 patients above 65 years old were included into the study.Compared with their status on admission,their grip strength,upper arm circumference and crural circumference were reduced significantly at discharge (P＜0.05).The total protein,albumin and hemoglobin levels were significantly lower than those on admission (P＜0.05).The incidence of nutritional risk (NRS 2002 score ≥ 3) and malnutrition (SGA B + C) on admission were lower than those at discharge (51.1％ vs 53.0％,32.6％ vs 35.6％).The hospitalization time and medical expenses were higher in patients with malnutrition on admission than in those with normal nutrition intakes.The nutritional status at discharge was negatively correlated with hospitalization time and medical expenses.61.3％ patients having nutritional risk did not take nutritional support during the hospital stay,while utilization rate of parenteral nutrition was higher than that of enteral nutrition in patients receiving nutritional support (19.6％ vs 11.9％).Conclusion Elderly patients have higher possibilities of facing nutritional risk or malnutrition on admission,these are associated with poor clinical outcomes and their nutritional status will not improve significantly at discharge.Therefore,the screening and evaluation of nutritional status in elderly patients during hospitalization should be conducted and their nutritional intervention should be standardized so as to improve the clinical outcomes.

Objective To set up and apply a standardized communication system of adolescents and young adults (AYAs) cancer patients,in order to improve AYAs cancer patients' psychological distress and other negative emotions,as well as promote social support and quality of life of patients.Methods A AYAs cancer patients standardized communication system,suitable for China's national conditions,was preliminarily built.Using randomized controlled trials,a total of 171 subjects,selected from 486 cases of AYAs cancer patients,in the Third Xiangya Hospital of Central South University and Hunan Cancer Hospital from August to September in 2016,were intervened with a set of standardized communication system.The Mental Distress Thermometer (DT),Hospital Anxiety and Depression Scale (HADS),Social Support Rating Scale (SSRS) and Concise Health Status Questionnaire (SF-36) were used as evaluation indexes to observe the psychological distress,emotion,social support and quality of life of the three groups of subjects before intervention,immediately after intervention,1 month after intervention and 3 months after intervention.Results At the follow-up of 3 months after intervention,38 cases were lost,14 cases in communication group (final n =43),11 cases in music therapy group (final n =46),and 13 cases in routine group (final n =44)..There was no significant difference in the evaluation indexes between the communication group,music treatment group and the routine group before intervention (P ＞ 0.05).There were statistically significant differences in scores of psychological pain,anxiety and depression,and social support in the 3 groups,before and immediately after intervention,1 month and 3 months after intervention (P ＜ 0.05).The scores of psychological pain,anxiety and depression,social support and quality of life in the communication group 1 month after intervention were statistically significant compared with those in the music group and the routine group (P ＜ 0.05).Conclusions Compared to music therapy and regular care,the standardized communication system has significant effect on improving the psychological distress of AYAs with cancer,and can also improve their social support level and quality of life.The clinical validation of the standardized communication system can provide reference for psychological rehabilitation of cancer survivors.

Objective To analyze the clinical characteristics and laboratory indexes of pneumonia complicated with pertussis syndrome in Suzhou area in order to provide the basis for rational treatment.Methods Children who had been hospitalized at Department of Respiratory,Children's Hospital of Soochow University during January 2012 to October 2016 were enrotled and diagnosed as pneumonia complicated with pertussis syndrome.A total of 236 cases were enrolled.Multiple pathogen detection and clinical information were collected in all patients.The subjects were divided into 28 days-＜ 3 months group,3-＜ 6 months old group,6-＜ 12 months old group and ≥ 12 months old group.The clinical data of children in each age group were retrospectively analyzed.Results Pneumonia complicated with pertussis syndrome was easy to occur within 6 months of infants,with the highest incidence in the 3-＜ 6 months group,there was a significant difference among the different age groups (x2 =231.870,P ＜ 0.05) [28 d-＜ 3 months group:5.3％ (102/1 910 cases),3-＜6 months group:5.7％ (76/1 341 cases),6-＜ 12 months group:2.0％ (36/1 762 cases),≥12 months group:0.4％ (22/5 304 cases)].The patients could become sick all the year round,with the highest incidence in summer[2.6％ (72/2 740 cases)in spring,3.7％ (96/2 611 cases)in summer,2.1％ (56/2 749 cases) in autumn,and 0.48％ (12/2 487 cases)in winter],and there were significant differences among the different seasons (x2 =62.380,P ＜0.001).Clinical symptoms were paroxysmal spasmodic cough,33.0％ (78/236 cases) of the performance with wheezing,mainly in the older than 3 months group.The incidence of fever was positively correlated with age(x2 =12.938,P ＜ 0.05).Peripheral white blood cell count and lymphocyte percentage increased,and the 3-＜ 6 months old group increased markedly.White blood cell count as high as (19.01 ± 11.99) × 109/L,the highest percentage of lymphocytes was up to 0.80,platelets were significantly increased in more than 80％ of children.The incidence of C-reactive protein (CRP) was negatively correlated with age,28 days-＜ 3 months group more prone to have high CRP.Pulmonary inflammatory pathology showed multiple pulmonary involvement by chest radiography,and it was more likely to occur in 28 d-＜ 3 months group.Viruses,bacteria and mycoplasma pneumoniae (MP) could cause pneumonia associated with pertussis syndrome,and mixed infection occurred in 56 cases.The top three pathogens were rhinovirus,MP and Streptococcus pneumoniae,and mixed infection was more prone to occur in 28 d-＜ 3 months group.Conclusion Pneumonia complicated with pertussis syndrome is easy to occur within 6 months of infants,with the highest incidence in summer.Viruses,bacteria and MP all could cause pneumonia associated with pertussis syndrome,and mixed infection could occur in some cases.The top three pathogens are rhinovirus,MP and Streptococcus pneumoniae.

Objective To understand the health literacy status,influencing factors and demand carrying out the health education based on the mobile terminal among college students to provide a new idea for formulating and implementing the health literacy promotion plan for university students.Methods The multi-stage stratified cluster random sampling method was adopted to extract 1 949 students from partial universities in Nanjing City and conduct the investigation by adopting the Rapid Estimate System of Health Literacy and Health Education Demand Based on the Mobile Terminal Questionnaire of College Students.The influence factors were analyzed by using the univariate analysis and ordinal multi-classification Logistic regression analy sis.Results The university students with high,marginal and low health literacy level accounted for 31.3％,48.9％ and 19.8％ respectively.The proportions of the students with high health literacy in the four dimensions,including health knowledge,health behaviors,health skill and health status,were 57.9％,18.3％,61.0％ and 44.5％ respectively.The ordinal multi-classification Logistic regression analysis showed that the major influence factors affecting the health literacy of university students were gender,education background of mothers,majors,grades,electively taking the health education course.81.2 ％ of university students wanted to or urgently wanted to understand the health literacy knowledge.The main route getting the health literacy knowledge by the university students was network(83.8％).91.8％ of students were willing to learn the health literacy knowledge through mobile terminal.87.1％ of students believed that the WeChat was suitable to learn the health knowledge,81.3％ of students hoped to use the WeChat platform for learning the health knowledge,73.8％ of students hoped the Wechat to push the health knowledge with the modes of words combined with images and video.It was recommended that the health knowledge pushing for 1-3 times per week was suitable.Conclusion The health literacy of university students is at the marginal level.The health behaviors literacy is most lacking and the demand for the health education based on the mobile terminal is stronger.The health literacy intervention of university students should sufficiently apply the new media platform superiority and the emphasis should be placed on the populations of males,low education background mothers,non-medicine major,low grade and without electively taking the health education course.

Objective: To observe the distribution of occupational activity disorders of extremely severe mass burn patients in recovery period after injury. Methods: From December 2014 to December 2015, 65 extremely severe burn patients conforming to the inclusion criteria involved in August 2 Kunshan factory aluminum dust explosion accident were admitted to Kunshan Rehabilitation Hospital. They received comprehensive rehabilitation treatment after burns, including wearing pressure clothes, ultrasound treatment, semiconductor laser and red light irradiation, motor function training, and so on. Over 2 years after injury, a cross-sectional survey was conducted on the patients′ occupational activity disorders. Modified Barthel index (MBI) was used to assess the degree of activities of daily living (ADL) disorder of patients and to grade the independent level of completing each item of MBI, and then the independent level of patients completing self-care MBI items (bathing, dressing, grooming, eating, going to the toilet, urine control, and stool control) was compared with that of mobility items (going up and down stairs, bed and chair transfer, and walking). The Canadian Occupational Performance Measure (COPM) was used to assess the distribution of occupational activity disorders of patients. The distribution of the five most serious occupational activity disorders was counted, then the frequency and probability of which with frequency greater than or equal to 16 times were calculated. Data were processed with Pearson Chi-square test. Results: Over 2 years after injury, the MBI score of patients was (76±22) points, and the ADL of 83.08% (54/65) patients reached completely self-care or light ADL disorder level. The MBI items arranged according to the completing independent level of patients from high to low were urine control/stool control, walking, bed and chair transfer, going up and down stairs, going to the toilet, eating, grooming, dressing, and bathing. The independent level of patients completing self-care MBI items was lower than that of mobility items (χ²=62.298, P<0.001). Over 2 years after injury, the five most serious occupational activity disorders in COPM dimension were mainly concentrated in the self-care dimension, accounting for 55.38% (180/325), followed by 22.46% (73/325) of production activities and 22.15% (72/325) of recreational activities, and the centrally distributed item was the personal self-care item under self-care dimension, accounting for 42.46% (138/325). Over 2 years after injury, the five most serious occupational activity disorders with frequency greater than or equal to 16 times were dressing and undressing, bathing, perineal cleaning, wearing pressure clothes, caring for children, visiting relatives and friends, 31, 25, 16, 17, 18, and 22 times respectively, with a probability of 47.69%, 38.46%, 24.62%, 26.15%, 27.69%, and 33.85% respectively. Conclusions: Over 2 years after injury, most of the patients with extremely severe burns caused by the aluminum dust explosion were completely or basically self-care in their daily life. The disorder of self-care ADL was more serious than that of mobility, and the disorder of individual self-care activity was still the most serious occupational activity disorder of patients in this stage.
